("SUPPLEMENTAL INDENTURE"), to the Indenture dated as of February 12, 2001 (as
amended, modified or supplemented from time to time in accordance therewith, the
"INDENTURE"), by and among MASCO CORPORATION, a Delaware corporation (the
"COMPANY") and J.P. MORGAN TRUST COMPANY, NATIONAL ASSOCIATION (successor in
interest to Bank One Trust Company, National Association) as trustee (the
"TRUSTEE").

         Each party agrees as follows for the benefit of the other party and for
the equal and ratable benefit of the holders of Notes (as defined herein):

         WHEREAS, the Company and the Trustee have duly authorized the execution
and delivery of the Indenture to provide for the issuance from time to time of
senior debt securities (the "SECURITIES") to be issued in one or more series as
in the Indenture provided;

         WHEREAS, the Company desires and has requested the Trustee to join it
in the execution and delivery of this Supplemental Indenture in order to
establish and provide for the issuance by the Company of a series of Securities
designated as its Zero Coupon Convertible Senior Notes, Series B Due 2031 in the
aggregate principal amount at maturity of up to $1,874,975,000 (but not to
exceed the aggregate principal amount at maturity of the Company's Zero Coupon
Convertible Senior Notes Due 2031 exchanged for the Notes), substantially in the
form attached hereto as Exhibit A (the "NOTES"), on the terms set forth herein;

         WHEREAS, Section 2.01 of the Indenture provides that a supplemental
indenture may be entered into by the Company and the Trustee for such purpose
provided certain conditions are met;

         WHEREAS, the conditions set forth in the Indenture for the execution
and delivery of this Supplemental Indenture have been complied with; and

         WHEREAS, all things necessary to make this Supplemental Indenture a
valid agreement of the Company and the Trustee, in accordance with its terms,
and a valid amendment of, and supplement to, the Indenture have been done;

         NOW, THEREFORE:

         In consideration of the premises and the purchase and acceptance of the
Notes by the holders thereof, the Company covenants and agrees with the Trustee,
for the equal and ratable benefit of the holders, that the Indenture is
supplemented and amended, to the extent expressed herein, as follows:

                                    ARTICLE 1
                    SCOPE OF SUPPLEMENTAL INDENTURE; GENERAL

         The changes, modifications and supplements to the Indenture effected
by this Supplemental Indenture shall be applicable only with respect to, and
govern the terms of, the Notes, which shall be limited in aggregate principal
amount at maturity of up to $1,874,975,000 in one series, and shall not apply
to any other Securities that may be issued under the Indenture

<PAGE>

unless a supplemental indenture with respect to such other Securities
specifically incorporates such changes, modifications and supplements. Pursuant
to this Supplemental Indenture, there is hereby created and designated a series
of Securities under the Indenture entitled "Zero Coupon Convertible Senior
Notes, Series B Due 2031." The Notes shall be in the form of Exhibit A hereto.

         The aggregate Principal Amount of the Notes shall be payable on the
Final Maturity Date unless the Accreted Value or the Restated Principal Amount
has been earlier repaid or the Notes have been converted in accordance with this
Supplemental Indenture.

         The Notes shall be issued at an Initial Principal Amount of
$[_________] per $1,000 Principal Amount. Except as provided for in Sections
4.08 and 4.10 and paragraphs 1, 5 and 10 of the Notes, there shall be no
periodic payments of interest on the Notes. The calculation of the Accreted
Value in the period during which each Note remains outstanding shall be on a
semi-annual bond equivalent basis using a 360-day year composed of twelve 30-day
months, and such accrual shall commence on the Issue Date of the Notes. In the
event of the maturity, conversion, purchase by the Company at the option of the
Holder, or redemption of a Note, Accreted Value, if any, shall cease to accrue
on such Note, under the terms and subject to the conditions of this Supplemental
Indenture.

         The Notes shall be payable and may be presented for payment, purchase,
conversion, registration of transfer and exchange, without service charge, at
the office of the Company maintained for such purpose in New York, New York,
which shall initially be the office or agency of the Trustee.

                                    ARTICLE 2

contingent interest, if any, payable on the Redemption Date. The Company shall
give the Notice to the Trustee provided for in this Section 4.01(a) at least 30
days but not more than 60 days before the Redemption Date.

         (b) Selection of Notes to Be Redeemed. If any Note selected for partial
redemption is thereafter surrendered for conversion in part before termination
of the conversion right with respect to the portion of the Note so selected, the
converted portion of such Note shall be deemed (so far as may be), solely for
purposes of determining the aggregate Principal Amount of Notes to be redeemed
by the Company, to be the portion selected for redemption. Notes which have been
converted during a selection of Notes to be redeemed may be treated by the
Trustee as outstanding for the purpose of such selection. Nothing in this
Section 4.01(b) shall affect the right of any Holder to convert any Note
pursuant to Sections 4.05, 4.06 and 4.07 before the termination of the
conversion right with respect thereto.

         (c) Notice of Redemption. At least 30 days but not more than 60 days
before a Redemption Date, the Company shall provide Notice of redemption
("Redemption Notice") to the Trustee and to each Holder of Notes to be redeemed.

         The Notice shall identify the Notes to be redeemed and shall state:

                  (ii) the Redemption Price and, to the extent known at the time
         of such Notice, the amount of contingent interest, if any, payable on
         the Redemption Date;

                  (iv) the name and address of the Paying Agent and the
         Conversion Agent;

                  (v) that Notes called for redemption must be presented and
         surrendered to the Paying Agent to collect the Redemption Price and
         contingent interest, if any;

                                       10
<PAGE>

                  (vi) that the Notes called for redemption may be converted at
         any time before the close of business on the Business Day prior to the
         Redemption Date;

                  (vii) that Holders who wish to convert Notes must comply with
         the procedures in paragraph 9 of the Notes;

                  (viii) that, unless the Company defaults in making payment of
         such Redemption Price and contingent interest, if any, Accreted Value
         and interest (including contingent interest), if any, on the Notes
         called for redemption will cease to accrue on and after the Redemption
         Date and the only remaining right of the Holder will be to receive
         payment of the Redemption Price upon presentation and surrender to the
         Paying Agent of the Notes;

                  (ix) if fewer than all the outstanding Notes are to be
         redeemed, the certificate number and Principal Amounts at Final
         Maturity of the particular Notes to be redeemed; and

                  (x) the CUSIP number or numbers for the Notes called for
         redemption.

         At the Company's request, the Trustee shall give the Notice of
redemption in the Company's name and at the Company's expense.

         (d) Effect of Notice of Redemption. Once Notice of redemption is given,
Notes called for redemption become due and payable on the Redemption Date and at
the Redemption Price (together with accrued and unpaid contingent interest, if
any) stated in the Notice, except for Notes that are converted in accordance
with the provisions of Sections 4.05, 4.06 and 4.07. Upon presentation and
surrender to the Paying Agent, Notes called for redemption shall be paid at the
Redemption Price (together with accrued contingent interest, if any).

         (e) Sinking Fund. There shall be no sinking fund provided for the
Notes.

         (f) Deposit of Redemption Price. On or before 11:00 a.m. (New York City
time) on the Redemption Date, the Company shall deposit with the Trustee or with
the Paying Agent (or, if the Company or an Affiliate of the Company is acting as
the Paying Agent, shall segregate and hold in trust) an amount of money
sufficient to pay the aggregate Redemption Price of, and any accrued and unpaid
contingent interest with respect to, all the Notes to be redeemed on that date
other than the Notes or portions thereof called for redemption which on or prior
thereto have been delivered by the Company to the Trustee for cancellation or
have been converted in accordance with the provisions hereof. The Trustee and
the Paying Agent shall, as promptly as practicable, return to the Company any
money not required for that purpose because of conversion of the Notes in
accordance with the provisions of Sections 4.05, 4.06 and 4.07. If such money is
then held by the Company or a Subsidiary in trust and is not required for such
purpose, it shall be discharged from such trust.

                                       11
<PAGE>

Stock (the "ADDITIONAL SHARES") as described below; provided that if the Stock
Price is greater than $50.00 (the "STOCK PRICE CAP") or less than $25.51 (the
"STOCK PRICE THRESHOLD") (subject in each case to adjustment as described
below), the number of Additional Shares shall be zero. The Additional Shares
shall be in addition to, and not in substitution for, any cash or shares of
Common Stock otherwise due to Holders of Notes upon conversion, as described in
this Supplemental Indenture. Holders will not be entitled to receive Additional
Shares if a Holder elects to convert Notes in connection with a Change of
Control after January 20, 2007.

         The number of Additional Shares shall be determined by reference to the
table set forth below, based on the effective date of such Change of Control
transaction (the "EFFECTIVE DATE") and the Stock Price.

         Notwithstanding the foregoing, in no event shall the total number of
shares of Common Stock issuable upon conversion exceed 47.91 shares per $1,000
Principal Amount, subject to adjustment in the same manner as the Conversion
Rate as set forth in Section 4.06.

         Any Conversion of Notes in connection with a Change of Control as
provided in this Section and the settlement thereof shall be as set forth in

</TABLE>

         The exact Stock Price and Effective Dates may not be set forth on the
table, in which case, if the Stock Price is between two Stock Prices on the
table or the Effective Date is between two Effective Dates on the table, the
Additional Shares shall be determined by straight-line interpolation between
Additional Shares amounts set forth for the higher and lower Stock Prices and
the two Effective Dates, as applicable, based on a 365-day year. The Stock
Prices set forth in the column headers are subject to adjustment pursuant to
Section 4.06.

         (b) Public Acquirer Change of Control. In lieu of adjusting the
Conversion Rate as set forth above in Section 4.02(a), in the case of a Public
Acquirer Change of Control, the Company may elect that, from and after the
Effective Date of such Public Acquirer Change of Control, the right to convert a
Note into Cash and Common Stock will be changed into a right to convert a Note
into a number of shares of Acquirer Common Stock. The Conversion Rate following
the Effective Date of such transaction will be a number of shares of Acquirer
Common Stock equal to the product of:

                                       12
<PAGE>

                  (i) the Conversion Rate in effect immediately prior to the
         Effective Date of such Public Acquirer Change of Control, times

                  (ii) the average of the quotients obtained, for each Trading
         Day in the five consecutive Trading Day period commencing on the
         Trading Day next succeeding the Effective Date of such Public Acquirer
         Change of Control (the "VALUATION PERIOD"), of:

                           (A) the Acquisition Value of the Common Stock on each
                  such Trading Day in the Valuation Period, divided by

                           (B) the Sale Price of the Acquirer Common Stock on
                  each such Trading Day in the Valuation Period.

         After the adjustment of the Conversion Rate in connection with a Public
Acquirer Change of Control, the Conversion Rate will be subject to further
similar adjustments if any of the events described above occur thereafter.

         (c) Calculation Agent. A Calculation Agent appointed from time to time
by the Company shall, on behalf of and on request by the Company, calculate (A)
the Stock Price and (B) the Additional Shares with respect to such Stock Price,
based on the Effective Date specified by the Company, and shall deliver its
calculation of the Stock Price and Additional Shares to the Company and the
Trustee within three Business Days of the request by the Company or the Trustee.
In addition, the Calculation Agent shall, on behalf of and upon request by the
Company or the Trustee, determine the Acquisition Value described in Section
4.02(b) above and deliver its calculations to the Company or the Trustee by 9:00
p.m., New York City time, within three Business Days after the end of the
Valuation Period. The Company, or at the Company's request, the Trustee in the
name and at the expense of the Company, shall provide a Notice to the Holders,
of the Stock Price and Additional Shares per Principal Amount with respect to a
Change of Control as part of the Change of Control Notice. Upon a Public
Acquirer Change of Control, whereby the Company has elected to change the
conversion consideration pursuant to Section 4.02(b) above, the Company, or at
the Company's request, the Trustee in the name and at the expense of the
Company, shall provide a Notice to the Holders, promptly within three Business
Days after the end of the Valuation Period, of the number of shares of Acquirer
Common Stock into which the Notes are convertible after the Effective Date. Any
Notice so given shall be conclusively presumed to have been duly given, whether
or not the Holder receives such Notice. The Company shall verify, in writing,
all calculations made by the Calculation Agent pursuant to this Section 4.03(c).

         (d) Adjustment Related to Additional Shares. Whenever the Conversion
Rate shall be adjusted from time to time by the Company pursuant to Section
4.06, the Stock Price Threshold and the Stock Price Cap shall be adjusted and
each of the Stock Prices set forth in the Additional Shares Table shall be
adjusted. The adjusted Stock Price Threshold, Stock Price Cap and Stock Prices
set forth in the Additional Shares Table shall equal the Stock Price Threshold,
Stock Price Cap and such Stock Prices, as the case may be, immediately prior to
such adjustment multiplied by a fraction, the numerator of which is the
Conversion Rate immediately prior to the adjustment giving rise to such
adjustment and the denominator of which is the Conversion Rate so adjusted.

                                       13
<PAGE>

         (e) Change of Control Notice. As promptly as practicable, but in no
event less than 15 days prior to the Effective Date of a Change of Control, the
Company shall provide Notice of Change of Control ("CHANGE OF CONTROL NOTICE")
to the Trustee and to each Holder of Notes and shall state:

                  (i) the Effective Date and, briefly, the events causing such
         Change in Control;

                  (ii) the procedures the Holders must follow to exercise rights
         under Section 4.03 and this Section 4.02

                  (ii) specify whether we will adjust the Conversion Rate or
         elect to modify the conversion obligation, in accordance with Section
         4.02(b);

                  (iii) the then current Conversion Rate;

                  (iv) the number of Additional Shares; and

                  (v) the name and address of the Conversion Agent.

         Section 4.03. Purchase of Notes at the Option of the Holder.

         (a) Purchase of Notes at the Option of the Holder. On each of January
20, 2005, January 20, 2007, July 20, 2011, July 20, 2016, July 20, 2021 and July
20, 2026 (each, a "PURCHASE DATE"), at the purchase price specified in paragraph
7 of the Notes (each, a "PURCHASE PRICE"), a Holder of Notes shall have the
option to require the Company to purchase any outstanding Notes, upon:

                  (i) delivery to the Paying Agent by the Holder of a written
         Notice of purchase (a "PURCHASE NOTICE") at any time from the opening
         of business on the date that is 30 Business Days prior to a Purchase
         Date until the close of business on such Purchase Date, stating:

                           (A) if certificated, the certificate numbers of the
                  Notes which the Holder shall deliver to be purchased;

                           (B) the portion of the Principal Amount of the Notes
                  which the Holder shall deliver to be purchased, which portion
                  must be $1,000 in Principal Amount or a multiple thereof; and

                           (C) that such Notes shall be purchased as of the
                  Purchase Date pursuant to the terms and conditions specified
                  in paragraph 7 of the Notes and in this Supplemental
                  Indenture.

                  (ii) delivery or book-entry transfer of such Note to the
         Paying Agent prior to, on or after the Purchase Date (together with all
         necessary endorsements) at the offices of the Paying Agent, such
         delivery or transfer being a condition to receipt by the Holder of the
         Purchase Price therefor; provided, however, that such Purchase Price
         shall be so paid pursuant to this Section 4.03 only if the Note so
         delivered or transferred to the Paying

                                       14
<PAGE>

         Agent shall conform in all respects to the description thereof in the
         related Purchase Notice.

         (b) Procedures. The Company shall purchase from the Holder thereof,
pursuant to this Section 4.03, a portion of a Note if the Principal Amount of
such portion is $1,000 or a multiple of $1,000 if so requested by the Holder.
Provisions of this Supplemental Indenture that apply to the purchase of all of a
Note also apply to the purchase of such portion of such Note.

         Any purchase by the Company contemplated pursuant to the provisions of
this Section 4.03 shall be consummated by the delivery of Cash (together with
accrued and unpaid contingent interest, if any) promptly following the later of
the Purchase Date and the time of delivery or book-entry transfer of the Note.

         Notwithstanding anything herein to the contrary, any Holder delivering
to the Paying Agent the Purchase Notice contemplated by Section 4.03(a) shall
have the right at any time prior to the close of business on the Purchase Date
to withdraw such Purchase Notice (in whole or in part) by delivery of a written
notice of withdrawal to the Paying Agent in accordance with Section 4.04(a).

         The Paying Agent shall promptly notify the Company of the receipt by it
of any Purchase Notice or written notice of withdrawal thereof.

         (c) Delivery of Officers' Certificate. At least five Business Days
before the Company Notice Date, the Company shall deliver an Officers'
Certificate to the Trustee specifying:

                  (i) the information required by Section 4.03(e); and

                  (ii) whether the Company desires the Trustee to give the
         Company Notice required by Section 4.03(e).

         (d) Purchase with Cash. The Purchase Price in respect of which a
Purchase Notice pursuant to Section 4.03(a) has been given, or a specified
percentage thereof, shall be paid by the Company with Cash equal to the
aggregate Purchase Price, or such specified percentage thereof, as the case may
be, of such Notes.

         (e) Notice. The Company shall send a notice (a "COMPANY NOTICE") to the
Holders (and to beneficial owners if required by applicable law) at their
addresses shown in the Note register maintained by the Registrar, and delivered
to the Trustee, not less than 30 Business Days prior to the Purchase Date (the
"COMPANY NOTICE Date"); provided, however that the Company shall not be required
to give such Company Notice with respect to the January 20, 2005 Purchase Date.
Such Company Notice shall state that payments shall be made in Cash and shall
include a form of Purchase Notice to be completed by a Holder and shall state:

                  (i) the Purchase Price, the Conversion Rate and, to the extent
         known at the time of such Notice, the amount of contingent interest, if
         any, that will be payable with respect to the Notes on the Purchase
         Date;

                  (ii) the name and address of the Paying Agent and the
         Conversion Agent;

                                       15
<PAGE>

                  (iii) that Notes as to which a Purchase Notice has been given
         may be converted only if the applicable Purchase Notice has been
         withdrawn in accordance with the terms of this Supplemental Indenture;

                  (iv) that Notes must be surrendered to the Paying Agent to
         collect payment of the Purchase Price and contingent interest, if any;

                  (v) that the Purchase Price for any Note as to which a
         Purchase Notice has been given and not withdrawn, together with any
         accrued contingent interest payable with respect thereto, shall be paid
         promptly following the later of the Purchase Date and the time of
         surrender of such Note as described in (iv);

                  (vi) the procedures the Holder must follow under Section 4.03;

                  (vii) briefly, the conversion rights of the Notes;

                  (viii) that, unless the Company defaults in making payment of
         such Purchase Price and contingent interest, if any, Accreted Value and
         interest (including contingent interest), if any, on Notes covered by
         any Purchase Notice (or interest, if the Notes have been converted into
         Cash Pay Notes pursuant to Section 4.08 of this Supplemental Indenture,
         if any) will cease to accrue on and after the Purchase Date;

                  (ix) the CUSIP or ISIN number of the Notes; and

                  (x) the procedures for withdrawing a Purchase Notice.

         At the Company's request and at the Company's expense, the Trustee
shall give the Company Notice in the Company's name; provided, however, that, in
all cases, the text of the Company Notice shall be prepared by the Company.

         (f) Covenants of the Company. All shares of Common Stock delivered upon
conversion of the Notes shall be newly issued shares or treasury shares, shall
be fully paid and nonassessable and shall be free from preemptive rights and
free of any lien or adverse claim.

         The Company shall cause to have listed or quoted all such shares of
Common Stock on each United States national securities exchange or
over-the-counter or other domestic market on which the Common Stock is then
listed or quoted.

         (g) Procedure upon Purchase. On or before 11:00 a.m. (New York City
time) on the Business Day immediately following the Purchase Date, the Company
shall deposit with the Paying Agent Cash sufficient to pay the aggregate
Purchase Price of, and any accrued and unpaid contingent interest with respect
to, the Notes to be purchased pursuant to this Section 4.03. If the Paying Agent
holds, in accordance with the terms of the Indenture, money sufficient to pay
the Purchase Price of such Note on the Business Day following the Purchase Date,
then, on and after such date, such Note shall cease to be outstanding and
Accreted Value on such Note shall cease to accrue, whether or not book-entry
transfer of such Note is made or such Note is delivered to the Paying Agent, and
all other rights of the Holder shall terminate (other than the right to receive
the Purchase Price upon delivery or transfer of the Note).

                                       16
<PAGE>

         (h) Taxes. Nothing herein shall preclude any income tax withholding
required by law or regulations.

         Section 4.04. Further Conditions for Purchase at the Option of Holders.

         (a) Effect of Purchase Notice. Upon receipt by the Company of the
Purchase Notice specified in Section 4.03(a), the Holder of the Note in respect
of which such Purchase Notice was given shall (unless such Purchase Notice is
withdrawn as specified in the following two paragraphs) thereafter be entitled
to receive solely the Purchase Price and any accrued and unpaid contingent
interest, if any, with respect to such Note. Such Purchase Price and contingent
interest, if any, shall be paid to such Holder promptly following the later of
(x) the Purchase Date with respect to such Note (provided the conditions in
Section 4.03(a), have been satisfied) and (y) the time of delivery or book-entry
transfer of such Note to the Paying Agent by the Holder thereof in the manner
required by Section 4.03(a). Notes in respect of which a Purchase Notice has
been given by the Holder thereof may not be converted for shares of Common Stock
on or after the date of the delivery of such Purchase Notice, unless such
Purchase Notice has first been validly withdrawn as specified in the following
two paragraphs.

         A Purchase Notice may be withdrawn by means of a written notice of
withdrawal delivered to the office of the Paying Agent at any time prior to the
close of business on the Purchase Date to which it relates specifying:

                  (i) if certificated, the certificate number of the Notes in
         respect of which such notice of withdrawal is being submitted;

                  (ii) the Principal Amount of the Notes with respect to which
         such notice of withdrawal is being submitted; and

                  (iii) the Principal Amount, if any, of the Notes which remain
         subject to the original Purchase Notice and which has been or shall be
         delivered for purchase by the Company.

         A written notice of withdrawal of a Purchase Notice may be in the form
of a conditional withdrawal containing the information set forth in the
preceding paragraph and contained in a written notice of withdrawal delivered to
the Paying Agent as set forth in the preceding paragraph.

         There shall be no purchase of any Notes pursuant to Section 4.03 or
redemption pursuant to Section 4.01 if there has occurred prior to, on or after,
as the case may be, the giving, by the Holders of such Notes, of the required
Purchase Notice, or the giving by the Company of the required Redemption Notice,
and is continuing an Event of Default (other than an Event of Default that is
cured by the payment of the Purchase Price, and any accrued and unpaid
contingent interest with respect to all such Notes). The Paying Agent will
promptly return to the respective Holders thereof any Notes (x) with respect to
which a Purchase Notice, has been withdrawn in compliance with this Supplemental
Indenture, or (y) held by it during the continuance of an Event of Default
(other than an Event of Default that is cured by the payment of the Purchase
Price, and any accrued and unpaid contingent interest with respect to all such
Notes) in which case, upon such return, the Purchase Notice with respect thereto
shall be deemed to have been withdrawn.

                                       17
<PAGE>

         (b) Notes Purchased in Part. Any Note that is to be purchased only in
part shall be surrendered at the office of the Paying Agent (with, if the
Company or the Trustee so requires, due endorsement by, or a written instrument
of transfer in form satisfactory to the Company and the Trustee duly executed
by, the Holder thereof or such Holder's attorney duly authorized in writing) and
the Company shall execute and the Trustee shall authenticate and deliver to the
Holder of such Note, without service charge, a new Note or Notes, of any
authorized denomination as requested by such Holder in aggregate Principal
Amount equal to, and in exchange for, the portion of the Principal Amount of the
Note so surrendered which is not purchased or redeemed.

         (c) Covenant to Comply with Securities Laws upon Purchase of Notes. In
connection with any offer to purchase Notes under Section 4.03, the Company
shall (i) comply with Rules 13e-4 and 14e-1 (which terms, as used herein,
include any successor provision thereto) under the Exchange Act, if applicable;
(ii) file the related Schedule TO (or any successor schedule, form or report)
under the Exchange Act, if applicable; and (iii) otherwise comply with all
federal and state securities laws so as to permit the rights and obligations
under Section 4.03 to be exercised in the time and in the manner specified in
Section 4.03.

         (d) Repayment to the Company. The Trustee and the Paying Agent shall
return to the Company any Cash remains unclaimed as provided in paragraph 14 of
the Notes, together with interest that the Trustee has agreed to pay on the Cash
held by them for the payment of a Purchase Price or contingent interest, if any;
provided, however, that to the extent that the aggregate amount of Cash
deposited by the Company pursuant to Section 4.04(b) exceeds the aggregate
Purchase Price of, and any accrued and unpaid contingent interest with respect
to, the Notes or portions thereof which the Company is obligated to purchase as
of the Purchase Date, then promptly after the Business Day following the
Purchase Date, the Trustee and the Paying Agent shall return any such excess to
the Company together with interest that the Trustee has agreed to pay, if any,
while such Cash is held by the Trustee or the Paying Agent.

         Section 4.05. Conversion of Notes.

         (a) Right to Convert. A Holder of a Note may convert such Note at any
time during which the conditions stated in paragraph 9 of the Notes are met.
Subject to certain exceptions described under clause (d)(3) of in paragraph 9 of
the Notes, if a Holder surrenders its Notes for conversion, such holder will
receive, in respect of each $1,000 of Principal Amount:

                  (i) Cash in an amount (the "PRINCIPAL RETURN") equal to the
         lesser of (A) the Applicable Accreted Value and (B) the Conversion
         Value; and

                  (ii) if the Conversion Value is greater than the Applicable
         Accreted Value, a number of shares of Common Stock (the "NET SHARES")
         equal to the sum of the Daily Share Amounts (calculated as described
         below) for each Trading Day during the Applicable Conversion Reference
         Period (the "NET SHARE AMOUNT"); provided that, in lieu of the delivery
         of Net Shares, the Company may, at its option, deliver Cash or a
         combination of Cash and shares of Company Common Stock equal to the
         value of the sum of the Daily Share Amounts. For this purpose, the
         value of each Daily Share Amount shall be calculated using the Sale
         Price of Company Common Stock on each Trading Day in the Applicable
         Conversion Reference Period. If and to the extent that the Company

                                       18
<PAGE>

         makes such an election, references herein to "Net Share Amount" shall
         be deemed to be references to such amount in Cash or combination of
         Cash and Common Stock, as applicable.

         A Holder may convert a portion of the Principal Amount of a Note if the
portion is $1,000 or a multiple of $1,000. Provisions of this Supplemental
Indenture that apply to conversion of all of a Note also apply to conversion of
a portion of a Note.

         (b) Conversion Procedures. To convert a Note a Holder must satisfy the
requirements in paragraph 9 of the Notes. The date on which the Holder of Notes
satisfies all those requirements is the conversion date (the "CONVERSION DATE").
As soon as practicable, but in no event later than the third Business Day
following the determination of the Applicable Stock Price the Company shall
deliver to the Holder, through the Conversion Agent, the Principal Return, Net
Share Amount, if applicable, and Cash in lieu of any fractional share determined
pursuant to Section 4.05(c). The Person in whose name any Common Stock
certificate is registered shall be treated as a stockholder of record on and
after the Conversion Date; provided, however, that no surrender of a Note on any
date when the stock transfer books of the Company shall be closed shall be
effective to constitute the Person or Persons entitled to receive the Net Share
Amount upon such conversion as the record holder or holders of such shares of
Common Stock on such date, but such surrender shall be effective to constitute
the Person or Persons entitled to receive such shares of Common Stock as the
record holder or holders thereof for all purposes at the close of business on
the next succeeding day on which such stock transfer books are open; such
conversion shall be at the Conversion Rate in effect on the date that such Note
shall have been surrendered for conversion, as if the stock transfer books of
the Company had not been closed. Upon conversion of a Note, such Person shall no
longer be a Holder of such Note.

         No payment or adjustment shall be made for dividends on or other
distributions with respect to any Common Stock except as provided in Section
4.06. On conversion of a Note, that portion of Accreted Value (or interest, if
the Company has exercised its option to convert the Notes to Cash Pay Notes
pursuant to Section 4.08) attributable to the period from the Issue Date of the
Note to the Conversion Date and accrued contingent interest with respect to the
converted Note shall not be canceled, extinguished or forfeited, but rather
shall be deemed to be paid in full (except as contemplated in paragraph 10 of
the Notes) to the Holder thereof through delivery of the Principal Amount and
Net Share Amount, if applicable (together with the Cash payment, if any, in lieu
of fractional shares) in exchange for the Note being converted.

         If a Holder converts more than one Note at the same time, the Principal
Return, the Net Share Amount (together with the Cash payment, if any, in lieu of
fractional shares) shall be based on the total Principal Amount of the Notes
converted.

         Upon surrender of a Note that is converted in part, the Company shall
execute, and the Trustee shall authenticate and deliver to the Holder, a new
Note in an authorized denomination equal in Principal Amount (or the Restated
Principal Amount, if applicable) to the unconverted portion of the Note
surrendered.

         If the last day on which a Note may be converted is a legal holiday in
a place where a Conversion Agent is located, the Note may be surrendered to that
Conversion Agent on the next succeeding day that it is not a legal holiday.

                                       19

         (c) Cash Payments in Lieu of Fractional Shares. The Company shall not
issue a fractional share of Common Stock upon conversion of a Note. Instead the
Company shall deliver Cash for the current market value of the fractional share.
The current market value of a fractional share shall be determined to the
nearest 1/10,000th of a share by multiplying the Sale Price of a full share of
Common Stock on the Trading Day immediately preceding the Conversion Date by the
fractional amount and rounding the product to the nearest whole cent.

         (d) Taxes on Conversion. If a Holder converts a Note, the Company shall
pay any documentary, stamp or similar issue or transfer tax due on the issue of
shares of Common Stock upon the conversion. However, the Holder shall pay any
such tax which is due because the Holder requests the shares to be issued in a
name other than the Holder's name. The Conversion Agent may refuse to deliver
the certificates representing the Common Stock being issued in a name other than
the Holder's name until the Conversion Agent receives a sum sufficient to pay
any tax which shall be due because the shares are to be issued in a name other
than the Holder's name. Nothing herein shall preclude any tax withholding
required by law or regulations.

         (e) Company to Provide Stock. The Company shall, prior to issuance of
any Notes hereunder, and from time to time as may be necessary, reserve out of
its authorized but unissued Common Stock a sufficient number of shares of Common
Stock to permit the conversion of the Notes.

         All shares of Common Stock delivered upon conversion of the Notes shall
be newly issued shares or treasury shares, shall be duly and validly issued and
fully paid and nonassessable and shall be free from preemptive rights and free
of any lien or adverse claim.

         The Company shall endeavor promptly to comply with all federal and
state securities laws regulating the order and delivery of shares of Common
Stock upon the conversion of Notes, if any, and shall cause to have listed or
quoted all such shares of Common Stock on each United States national securities
exchange or over-the-counter or other domestic market on which the Common Stock
is then listed or quoted.

         Section 4.06. Adjustments to Conversion Rate.

         The Conversion Rate shall be adjusted from time to time by the Company
as follows:

         (a) In case the Company shall (i) pay a dividend, or make a
distribution, in shares of Common Stock or other capital stock, on Common Stock;
(ii) subdivide its outstanding Common Stock into a greater number of shares; or
(iii) combine its outstanding Common Stock into a smaller number of shares, the
Conversion Rate in effect immediately prior thereto shall be adjusted so that
the holder of any Note thereafter surrendered for conversion shall be entitled
to receive the number of shares of Common Stock which such holder would have
owned or have been entitled to receive after the happening of any of the events
described above had such Note been converted immediately prior to the happening
of such event. If any dividend or distribution of the type described in clause
(i) above is not so paid or made, the Conversion Rate shall again be adjusted to
the Conversion Rate which would then be in effect if such dividend or
distribution had not been declared. An adjustment made pursuant to this Section
4.06 shall become effective immediately after the Common Stock Record Date in
the case of a dividend and shall become effective immediately after the
effective date in the case of subdivision or combination.

                                       20
<PAGE>

         (b) In case the Company shall issue rights or warrants to all holders
of any class or series of its Common Stock entitling them (for a period expiring
within 60 days after the date fixed for determination of stockholders entitled
to receive such rights or warrants) to subscribe for or purchase Common Stock at
a price per share less than the Sale Price per share of Common Stock on the day
preceding the date of announcement of the Common Stock Record Date for the
determination of stockholders entitled to receive such rights or warrants, the
Conversion Rate in effect immediately prior thereto shall be adjusted so that
the same shall equal the Conversion Rate determined by multiplying the
Conversion Rate in effect immediately prior to the date of the issuance of such
rights or warrants by a fraction of which the numerator shall be the number of
shares of Common Stock outstanding on the date of issuance of such rights or
warrants plus the number of additional shares of Common Stock offered for
subscription or purchase, and of which the denominator shall be the number of
shares of Common Stock outstanding on the date of issuance of such rights or
warrants plus the number of shares which the aggregate offering price of the
total number of shares so offered would purchase at such Sale Price. Such
adjustment shall be made successively whenever any such rights or warrants are
issued, and shall become effective immediately after the opening of business on
the day following the Common Stock Record Date for the determination of the
stockholders entitled to receive such rights or warrants. To the extent that
shares of Common Stock are not delivered after the expiration of such rights or
warrants, the Conversion Rate shall be readjusted to the Conversion Rate which
would then be in effect had the adjustments made upon the issuance of such
rights or warrants been made on the basis of delivery of only the number of
shares of Common Stock actually delivered. If such rights or warrants are not so
issued, the Conversion Rate shall again be adjusted to be the Conversion Rate
which would then be in effect if such Common Stock Record Date for the
determination of stockholders entitled to receive such rights or warrants had
not been fixed. In determining whether any rights or warrants entitle the
holders to subscribe for or purchase shares of Common Stock at less than such
Sale Price, and in determining the aggregate offering price of such shares of
Common Stock, there shall be taken into account any consideration received by
the Company for such rights or warrants, the value of such consideration, if
other than cash, to be determined by the Board of Directors.

         (c) In case the Company shall, by dividend or otherwise, distribute to
all holders of its Common Stock (excluding any distribution in connection with
the liquidation, dissolution or winding up of the Company, whether voluntary or
involuntary) any evidences of its indebtedness or assets (other than Cash
dividends or other Cash distributions from the Company's current or retained
earnings) or rights or warrants to subscribe for or purchase any of its
securities (excluding those referred to in Section 4.06(b)) (any of the
foregoing hereinafter in this Section 4.06(c) called the "DISTRIBUTED
SECURITIES"), then, the Conversion Rate shall be adjusted so that the same shall
equal the Conversion Rate determined by multiplying the Conversion Rate in
effect immediately prior to the date of such distribution by a fraction of which
the numerator shall be the Market Price per share of the Common Stock on the
Common Stock Record Date mentioned below, and the denominator shall be the Sale
Price per share of the Common Stock on such Common Stock Record Date less the
fair market value on such Common Stock Record Date (as determined by the Board
of Directors, whose determination shall be conclusive, and described in a
certificate filed with the Trustee) of the Distributed Securities so distributed
applicable to one share of Common Stock. Such adjustment shall become effective
immediately after the Common Stock Record Date for the determination of
stockholders entitled to receive such distribution. Notwithstanding the
foregoing, in the event (a) the then fair market value (as so determined) of the
portion of the Distributed Securities so distributed applicable to one share

                                       21
<PAGE>

of Common Stock is equal to or greater than the Market Price of the Common Stock
on the Common Stock Record Date or (b) such Market Price exceeds the fair market
value of such Distributed Securities by less than $1.00, in lieu of the
foregoing adjustment, adequate provision shall be made so that each Holder shall
have the right to receive upon conversion the amount of Distributed Securities
such Holder would have received had such Holder converted each Note on such
Common Stock Record Date. In the event that such distribution is not so paid or
made, the Conversion Rate shall again be adjusted to the Conversion Rate which
would then be in effect if such distribution had not been declared. If the Board
of Directors determines the fair market value of any distribution for purposes
of this Section 4.06(c) by reference to the actual or when issued trading market
for any securities, it must in doing so consider the prices in such market on
the same day used in computing the Sale Price of the Common Stock.

         Notwithstanding the foregoing provisions of this Section 4.06(c), no
adjustment shall be made thereunder for any distribution of Distributed
Securities if the Company makes proper provision so that each Holder of a Note
who converts such Note (or any portion thereof) after the Common Stock Record
Date for such distribution shall be entitled to receive upon such conversion, in
addition to the shares of Common Stock issuable upon such conversion, the amount
and kind of Distributed Securities that such Holder would have been entitled to
receive if such Holder had, immediately prior to such Common Stock Record Date,
converted such Note for Common Stock; provided that, with respect to any
Distributed Securities that are convertible, exchangeable or exercisable, the
foregoing provision shall only apply to the extent (and so long as) the
Distributed Securities receivable upon conversion of such Note would be
convertible, exchangeable or exercisable, as applicable, without any loss of
rights or privileges for a period of at least 60 days following conversion of
such Note.

         (d) In case the Company shall, by dividend or otherwise, distribute to
all holders of any class of its Common Stock Cash (excluding any Cash that is
distributed upon a merger or consolidation to which Section 4.07(f) applies) in
an aggregate amount that, combined together with (i) the aggregate amount of any
other such distributions to all holders of any class of its Common Stock made
exclusively in Cash within the 12 months preceding the date of payment of such
distribution, and in respect of which no adjustment pursuant to this Section
4.06(d) has been made, and (ii) the aggregate of any Cash plus the fair market
value of other consideration (as so determined by the Board of Directors, whose
determination shall be conclusive, and described in a certificate filed with the
Trustee) payable in respect of any tender offer by the Company for all or any
portion of any class of its Common Stock concluded within the 12 months
preceding the date of payment of such distribution, and in respect of which no
adjustment pursuant to Section 4.06(e) has been made, unless, beginning July 20,
2007, the annualized amount per share of Common Stock of any such dividend or
distribution made on or after July 20, 2007 exceeds 10% of the product of the
Sale Price on the day preceding the date of declaration of such dividend or
distribution times the number of shares of Common Stock outstanding on such
date, then, and in each such case, immediately after the close of business on
such date, the Conversion Rate shall be increased so that the same shall equal
the Conversion Rate determined by multiplying the Conversion Rate in effect
immediately prior to the Common Stock Record Date by a fraction of which the
numerator shall be such Sale Price of the Common Stock and the denominator shall
be such Sale Price of the Common Stock less the amount of Cash and the fair
market value (as so determined) of such other consideration so distributed (and
not excluded as provided above) applicable to one share of Common Stock, such
increase to be effective immediately prior to the opening of business on the day
following the Common Stock Record Date; provided, however,

                                       22
<PAGE>

that no adjustment will be made in respect of any such dividends and
distributions that are paid during any period for which the Company is paying
contingent interest to Holders; provided, further, that, if the portion of the
cash so distributed applicable to one share of Common Stock is (i) equal to or
greater than the Market Price of the Common Stock on the day preceding the date
of declaration of such dividend or distribution or (ii) the Market Price of the
Common Stock on the day preceding the date of declaration of such dividend or
distribution is greater than the fair market value of the consideration
distributed pursuant to Section 4.06(e) by less than $1.00, then, in lieu of the
foregoing adjustment, adequate provision shall be made so that each Holder shall
have the right to receive upon conversion, in addition to the shares of Common
Stock, Cash and other consideration the Holder would have received had such
Holder converted such Note immediately prior to such Common Stock Record Date.
If such dividend or distribution is not so paid or made, the Conversion Rate
shall again be adjusted to be the Conversion Rate which would then be in effect
if such dividend or distribution had not been declared. If any adjustment is
required to be made as set forth in this Section 4.06(d) as a result of a
distribution that is a quarterly dividend, such adjustment shall be based upon
the amount by which such distribution exceeds the amount of the quarterly cash
dividend permitted to be excluded pursuant hereto. If an adjustment is required
to be made as set forth in this Section 4.06(d) above as a result of a
distribution that is not a quarterly dividend, such adjustment shall be based
upon the full amount of the distribution.

         (e) In case a tender offer made by the Company or any of its
subsidiaries for all or any portion of any class of its Common Stock expires and
such tender offer (as amended upon the expiration thereof) requires the payment
to stockholders (based on the acceptance (up to any maximum specified in the
terms of the tender offer) of Purchased Shares) for an aggregate consideration
having a fair market value (as determined by the Board of Directors, whose
determination shall be conclusive and described in a resolution of the Board of
Directors) that, combined together with (a) the aggregate of the Cash plus the
fair market value (as determined by the Board of Directors, whose determination
shall be conclusive and described in a resolution of the Board of Directors), as
of the expiration of such tender offer, of consideration payable in respect of
any other tender offers, by the Company or any of its subsidiaries for all or
any portion of any class of its Common Stock expiring within the 12 months
preceding the expiration of such tender offer and in respect of which no
adjustment pursuant to this Section 4.06(e) has been made, and (b) the aggregate
amount of any distributions to all holders of the Common Stock made exclusively
in Cash within 12 months preceding the expiration of such tender offer and in
respect of which no adjustment pursuant to Section 4.06(d) has been made (except
as excluded by the first parenthetical phrase thereof), exceeds 10% of the
product of the Market Price (determined as provided herein) as of the last time
(the "EXPIRATION TIME") tenders could have been made pursuant to such tender
offer (as it may be amended) times the number of shares of Common Stock
outstanding (including any tendered shares) at the Expiration Time, then, and in
each such case, immediately prior to the opening of business on the day after
the date of the Expiration Time, the Conversion Rate shall be increased so that
the same shall equal the Conversion Rate determined by multiplying the
Conversion Rate in effect immediately prior to the Expiration Time by a fraction
of which the numerator shall be the sum of (x) the fair market value (determined
as aforesaid) of the aggregate consideration payable to stockholders based on
the acceptance (up to an maximum specified in the terms of the tender or
exchanged offer) of all shares validly tendered or exchanged and not withdrawn
as of the Expiration Time (the shares deemed so accepted, up to any such
maximum, being referred to as the "PURCHASED SHARES") and (y) the product of the
number of shares of Common Stock outstanding (less any Purchased

                                       23
<PAGE>

Shares) on the Expiration Time and the Market Price of the Common Stock on the
Trading Day next succeeding the Expiration Time and the denominator shall be the
number of shares of Common Stock outstanding (including any tendered or
exchanged shares) on the Expiration Time multiplied by the Market Price of the
Common Stock on the Trading Day next succeeding the Expiration Time, such
increase (if any) to become effective immediately prior to the opening of
business on the day following the Expiration Time. If the Company is obligated
to purchase shares pursuant to any such tender offer, but the Company is
permanently prevented by applicable law from effecting any such purchases or all
such purchases are rescinded, the Conversion Rate shall again be adjusted to be
the Conversion Rate which would then be in effect if such tender offer had not
been made.

         (f) If prior to July 20, 2007 the Company makes a dividend or other
distribution consisting exclusively of Cash to all holders of Common Stock, the
Conversion Rate will be adjusted based on the following formula:

             SP
               0
CR = CR x  -------
  1    0   SP - ED
             0

where,

     CR   = the Conversion Rate in effect immediately prior to the Common
       0    Stock Record Date for such Cash dividend or distribution;

     CR   = the Conversion Rate in effect immediately after the ex dividend
       1    date for such Cash dividend or distribution;

     SP   = the average of the Sale Prices of Common Stock for the ten
       0    consecutive Trading Days prior to the Trading Day immediately
            preceding the ex dividend date of such Cash dividend or
            distribution; and

     ED   = the amount by which such Cash dividend or distribution together
            with all other such Cash dividends or distributions made during the
            fiscal quarter (and for which no adjustment has been made), exceeds
            $0.18 per share (appropriately adjusted from time to time for any
            share dividends on or subdivisions of Common Stock).

         (g) For purposes of this Section 4.06, the number of shares of Common
Stock at any time outstanding shall not include shares held in the treasury of
the Company but shall include shares issuable in respect of scrip certificates
issued in lieu of fractions of shares of Common Stock. The Company shall not pay
any dividend or make any distribution on shares of Common Stock held in the
treasury of the Company.

         Section 4.07.  Miscellaneous Provisions Relating to Conversion.

         (a) When Adjustment May be Deferred. No adjustment in the Conversion
Rate need be made unless the adjustment would require an increase or decrease of
at least 1% in the Conversion Rate then in effect; provided that any adjustment
that would otherwise be required to be made shall be carried forward and taken
into account in any subsequent adjustment. Except as stated in Section 4.06, the
Conversion Rate will not be adjusted for the issuance of Common

                                       24
<PAGE>

Stock or any securities convertible into or exchangeable for Common Stock or
carrying the right to purchase any of the foregoing. Any adjustments that are
made shall be carried forward and taken into account any subsequent adjustment.
All calculations under Sections 4.05, 4.06 and 4.07 shall be made to the nearest
cent or to the nearest 1/10,000th of a share, as the case may be.

         (b) When No Adjustment Required. No adjustment need be made for rights
to purchase Common Stock pursuant to a Company plan for reinvestment of
dividends or interest. No adjustment need be made for a change in the par value
or no par value of the Common Stock. To the extent the Notes become convertible
into cash, assets or property (other than securities of the Company or another
Person), no adjustment need be made thereafter as to the cash, assets or
property. Interest shall not accrue on the Cash.

         No adjustment need be made for a transaction referred to in Section
4.06(a), (b), (c), (d) or (e) if Holders participate in the transaction (without
converting their Notes) by receiving the same Cash, assets, property or
securities that they would have received had they converted their Notes
immediately prior to the Common Stock Record Date or the effective date of the
transaction as the case may be.

         (c) Notice of Adjustment. Whenever the Conversion Rate is adjusted, the
Company shall promptly provide to Holders a Notice of the adjustment. The
Company shall file with the Trustee and the Conversion Agent such Notice. The
certificate shall, absent manifest error, be conclusive evidence that the
adjustment is correct. Neither the Trustee nor any Conversion Agent shall be
under any duty or responsibility with respect to any such certificate except to
exhibit the same to any Holder desiring inspection thereof.

         (d) Voluntary Increase. The Company may make such increases in the
Conversion Rate, in addition to those required by Section 4.06, as the Board of
Directors considers to be advisable to avoid or diminish any income tax to
holders of Common Stock or rights to purchase Common Stock resulting from any
dividend or distribution of stock (or rights to acquire stock) or from any event
treated as such for income tax purposes. To the extent permitted by applicable
law, the Company may from time to time increase the Conversion Rate by any
amount for any period of time if the period is at least 20 days, the increase is
irrevocable during the period and the Board of Directors shall have made a
determination that such increase would be in the best interests of the Company,
which determination shall be conclusive. Whenever the Conversion Rate is so
increased, the Company shall provide to Holders and file with the Trustee and
the Conversion Agent a Notice of such increase. Neither the Trustee nor any
Conversion Agent shall be under any duty or responsibility with respect to any
such certificate except to exhibit the same to any holder desiring inspection
thereof. The Company shall provide the Notice at least 15 days before the date
the increased Conversion Rate takes affect. The Notice shall state the increased
Conversion Rate and the period it shall be in effect.

         (e) Notice to Holders Prior to Certain Actions. In case:

                  (i) the Company shall declare a dividend (or any other
         distribution) on its Common Stock that would require an adjustment in
         the Conversion Rate pursuant to Section 4.06;

                                       25
<PAGE>

                  (ii) the Company shall authorize the granting to all or
         substantially all the Holders of its Common Stock of rights or warrants
         to subscribe for or purchase any share of any class or any other rights
         or warrants to purchase Common Stock;

                  (iii) of any reclassification or reorganization of the Common
         Stock of the Company (other than a subdivision or combination of its
         outstanding Common Stock, or a change in par value, or from par value
         to no par value, or from no par value to par value), or of any
         consolidation or merger to which the Company is a party and for which
         approval of any shareholders of the Company is required, or of the sale
         or transfer of all or substantially all of the assets of the Company
         (other than a Change of Control); or

                  (iv) of the voluntary or involuntary dissolution, liquidation
         or winding-up of the Company,

the Company shall cause to be filed with the Trustee and to be provided to
Holders of Notes, as promptly as possible but in any event at least 20 days
prior to the applicable date hereinafter specified, a Notice stating (x) the
date on which a record is to be taken for the purpose of such dividend,
distribution or rights or warrants, or, if a record is not to be taken, the date
as of which the holders of Common Stock of record to be entitled to such
dividend, distribution, or rights or warrants are to be determined or (y) the
date on which such reclassification, consolidation, merger, sale, transfer,
dissolution, liquidation or winding-up is expected to become effective or occur,
and the date as of which it is expected that holders of Common Stock of record
shall be entitled to exchange their Common Stock for securities or other
property deliverable upon such reclassification, consolidation, merger, sale,
transfer, dissolution, liquidation or winding-up. Failure to give such Notice,
or any defect therein, shall not affect the legality or validity of such
dividend, distribution, reclassification, consolidation, merger, sale, transfer,
dissolution, liquidation or winding-up.

         (f) Effect of Reclassification, Consolidation, Merger or Sale. If any
of the following events occur, namely (i) any reclassification or change of
outstanding shares of Common Stock (other than a change in par value, or from
par value to no par value, or from no par value to par value, or as a result of
a subdivision or combination); (ii) any consolidation, merger or combination of
the Company with another corporation as a result of which holders of Common
Stock shall be entitled to receive stock, securities or other property or assets
(including Cash) with respect to or in exchange for such Common Stock; or (iii)
any sale or conveyance of the properties and assets of the Company as, or
substantially as, an entirety to any other corporation as a result of which
holders of Common Stock shall be entitled to receive stock, securities or other
property or assets (including Cash) with respect to or in exchange for such
Common Stock, then, unless the provisions of Section 4.02 hereof shall apply to
such transaction, the Company or the successor or purchasing corporation, as the
case may be, shall execute with the Trustee a supplemental indenture, providing
that each Note shall be convertible into the kind and amount of shares of stock
and other securities or property or assets (including Cash) receivable upon such
reclassification, change, consolidation, merger, combination, sale or conveyance
by a holder of a number of shares of Common Stock issuable upon conversion of
such Notes immediately prior to such reclassification, change, consolidation,
merger, combination, sale or conveyance. Such supplemental indenture shall
provide for adjustments which shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Section 4.07(f).

                                       26
<PAGE>

         The Company shall cause Notice of the execution of such supplemental
indenture to be provided to Holders of Notes, within 20 days after execution
thereof. Failure to deliver such Notice shall not affect the legality or
validity of such supplemental indenture.

         The above provisions of this Section shall similarly apply to
successive reclassifications, changes, consolidations, mergers, combinations,
sales and conveyances.

         If this Section 4.07(f) applies to any event or occurrence, Section
4.06 shall not apply.

         (g) Responsibility of Trustee. The Trustee and any other Conversion
Agent shall not at any time be under any duty or responsibility to any Holder of
Notes to either calculate the Conversion Rate or determine whether any facts
exist which may require any adjustment of the Conversion Rate, or with respect
to the nature or extent or calculation of any such adjustment when made, or with
respect to the method employed, or herein or in any supplemental indenture
provided to be employed, in making the same and shall be protected in relying
upon an Officer's Certificate with respect to the same. The Trustee and any
other Conversion Agent shall not be accountable with respect to the validity or
value (or the kind or amount) of any shares of Common Stock, or of any
securities or property, which may at any time be issued or delivered upon the
conversion of any Note and the Trustee and any other Conversion Agent make no
representations with respect thereto. Subject to the provisions of Article Six
of the Indenture, neither the Trustee nor any Conversion Agent shall be
responsible for any failure of the Company to issue, transfer or deliver any
shares of Common Stock or stock certificates or other securities or property or
Cash upon the surrender of any Note for the purpose of conversion or to comply
with any of the duties, responsibilities or covenants of the Company contained
in this Section. Without limiting the generality of the foregoing, neither the
Trustee nor any Conversion Agent shall be under any responsibility to determine
the correctness of any provisions contained in any supplemental indenture
entered into pursuant to Section 4.07(f) relating either to the kind or amount
of shares of stock or securities or property (including Cash) receivable by
Holders upon the conversion of their Notes after any event referred to in such
Section 4.07(f) or to any adjustment to be made with respect thereto, but,
subject to the provisions of Article Six of the Indenture, may accept as
conclusive evidence of the correctness of any such provisions, and shall be
protected in relying upon, the Officer's Certificate (which the Company shall be
obligated to file with the Trustee prior to the execution of any such
supplemental indenture) with respect thereto.

            (h) Simultaneous Adjustments. In the event that Sections 4.05, 4.06
or 4.07 require adjustments to the Conversion Rate under more than one of
Section 4.06(a), (b), (c) or (d), and the Common Stock Record Dates for the
distributions giving rise to such adjustments shall occur on the same date, then
such adjustments shall be made by applying, first, the provisions of Section
4.06(c), second, the provisions of Section 4.06(d), third, the provisions of
Section 4.06(a), and fourth, the provisions of Section 4.06(b).

         (i) Successive Adjustments. After an adjustment to the Conversion Rate
under Sections 4.05, 4.06 or 4.07, any subsequent event requiring an adjustment
under Sections 4.05, 4.06 or 4.07 shall cause an adjustment to the Conversion
Rate as so adjusted.

         (j) General Considerations. Whenever successive adjustments to the
Conversion Rate are called for pursuant to Sections 4.05, 4.06 or 4.07, such
adjustments shall be made to the Sale

                                       27
<PAGE>

Price or Market Price as may be necessary or appropriate to effectuate the
intent of Sections 4.05, 4.06 or 4.07 and to avoid unjust or inequitable results
as determined in good faith by the Board of Directors.

         (k) Stockholder Rights Plans. Upon conversion of the Notes the Holders
shall receive, in addition to the Common Stock issuable upon such conversion,
any rights issued under any stockholder rights plan the Company shall have
implemented (notwithstanding the occurrence of an event causing such rights to
separate from the Common Stock at or prior to the time of conversion).

         Section 4.08. Optional Conversion to Semi-Annual Cash Pay Note Upon Tax
Event.

         From and after (i) the date (the "TAX EVENT DATE") of the occurrence of
a Tax Event and (ii) the date the Company exercises its option set forth in this
4.08, whichever is later (the "OPTION EXERCISE DATE"), at the option of the
Company, cash interest in lieu of future Accreted Value shall accrue at the rate
of 3.125% per annum on a restated principal amount per $1,000 original Principal
Amount (the "RESTATED PRINCIPAL AMOUNT") equal to its Accreted Value on the
Option Exercise Date and shall be payable semi-annually on July 20 and January
20 of each year (each an "INTEREST PAYMENT DATE") to holders of record at the
close of business on July 1 and January 1 (each a "REGULAR RECORD DATE")
immediately preceding such Interest Payment Date. Interest will be computed on
the basis of a 360-day year comprised of twelve 30-day months and will accrue
from the most recent date on which interest has been paid or, if no interest has
been paid, from the Option Exercise Date. Within 15 days of the occurrence of a
Tax Event, the Company shall deliver a written Notice of such Tax Event by
facsimile and first-class mail to the Trustee and within 15 days of their
exercise of such option the Company shall deliver a written Notice of the Option
Exercise Date by facsimile and first-class mail to the Trustee and provide
Notice to the Holders of the Notes. From and after the Option Exercise Date, (i)
the Company shall be obligated to pay at Maturity or upon a Redemption Date or
Purchase Date, in lieu of the Principal Amount or Accreted Value, as applicable,
of a Note, the Restated Principal Amount thereof plus accrued and unpaid
interest and (ii) contingent interest shall cease to accrue on the Notes. Notes
authenticated and delivered after the Option Exercise Date may, and shall if
required by the Trustee, bear a notation in a form approved by the Trustee as to
the conversion of the Notes to Cash Pay Notes.

         Section 4.09. Calculation of Original Issue Discount for U.S. Federal
Income Tax Purposes.

         The Company agrees, and each Holder and any beneficial holder of a Note
by its purchase thereof shall be deemed to agree, to treat (in the absence of an
administrative determination or judicial ruling to the contrary), for United
States federal income tax purposes, the Notes as contingent payment debt
instruments subject to Section 1.1275-4 of the Treasury Regulations. For United
States federal income tax purposes, interest will accrue on the Notes as
original issue discount according to the "noncontingent bond method," set forth
in Section 1.1275- (b) of the Treasury Regulations, based on a comparable yield
of 8.125% compounded semi-annually and the projected payment schedule attached
hereto as Exhibit B.

         The Company acknowledges and agrees, and each Holder and any beneficial
holder of a Note by its purchase thereof shall be deemed to acknowledge and
agree, that (i) the comparable

                                       28
<PAGE>

yield means the annual yield the Company would pay, as of the Issue Date, on a
fixed-rate cash pay nonconvertible debt security with no contingent payments,
but with terms and conditions otherwise comparable to those of the Notes; (ii)
the schedule of projected payments attached hereto as Exhibit B is determined on
the basis of the comparable yield and an assumption of linear growth of the
stock price and a constant dividend yield; (iii) the comparable yield and the
schedule of projected payments are not determined for any purpose other than for
the determination of interest accruals and adjustments thereof in respect of the
Notes for United States federal income tax purposes; and (iv) the comparable
yield and the schedule of projected payments do not constitute a projection or
representation regarding the future stock price or the amounts payable on the
Notes.

         Section 4.10. Payment of Interest.

         (a) Paying Agent to Hold Money in Trust. Prior to 11:00 a.m. (New York
City time) on any applicable Interest Payment Date, the Company shall deposit
with the Paying Agent (or if the Company or a Subsidiary is acting as Paying
Agent, segregate and hold in trust for the benefit of the Persons entitled
thereto) a sum sufficient to pay semi-annual or contingent interest when due.
The Company shall require each Paying Agent (other than the Trustee) to agree in
writing that the Paying Agent shall hold in trust for the benefit of Holders or
the Trustee all money held by the Paying Agent for the payment of principal or
interest on the Notes and shall notify the Trustee of any default by the Company
in making any such payment. The Company at any time may require a Paying Agent
to pay all money held by it to the Trustee and to account for any funds
disbursed by the Paying Agent. Upon complying with this Section, the Paying
Agent shall have no further liability for the money delivered to the Trustee.

         (b) Holder Lists. The Trustee shall preserve in as current a form as is
reasonably practicable the most recent list available to it of the names and
addresses of Holders. If the Trustee is not the Registrar, the Company shall
furnish, or cause the Registrar to furnish, to the Trustee, in writing at least
five Business Days before each Interest Payment Date and at such other times as
the Trustee may request in writing, a list in such form and as of such date as
the Trustee may reasonably require of the names and addresses of Holders.

         (c) Payment of Interest; Interest Rights Preserved.

                  (i) Semi-annual or contingent interest on any Note that is
         payable, and is punctually paid or duly provided for, on any Interest
         Payment Date shall be paid to the Person in whose name that Note is
         registered at the close of business on the Regular Record Date or
         accrual date, as the case may be, for such interest at the office or
         agency of the Company maintained for such purpose. Each installment of
         semi-annual or contingent interest on any Note shall be paid in
         same-day funds by transfer to an account maintained by the payee
         located inside the United States. In the case of a Global Note,
         semi-annual or contingent interest payable on any applicable payment
         date will be paid to the depository, with respect to that portion of
         such Global Note held for its account by Cede & Co. for the purpose of
         permitting such party to credit the interest received by it in respect
         of such Global Note to the accounts of the beneficial owners thereof.

                  (ii) Except as otherwise specified with respect to the Notes,
         any semi-annual or contingent interest on any Note that is payable, but
         is not punctually paid or duly

                                       29
<PAGE>

         provided for, within 30 days following any applicable payment date
         (herein called "DEFAULTED INTEREST", which term shall include any
         accrued and unpaid interest that has accrued on such defaulted amount
         in accordance with paragraph 1 of the Notes), shall forthwith cease to
         be payable to the registered Holder thereof on the relevant Regular
         Record Date or accrual date, as the case may be, by virtue of having
         been such Holder, and such Defaulted Interest may be paid by the
         Company, at its election in each case, as provided in clause (A) or (B)
         below.

                           (A) The Company may elect to make payment of any
                  Defaulted Interest to the Persons in whose names the Notes are
                  registered at the close of business on a date for the payment
                  of such Defaulted Interest (the "SPECIAL RECORD DATE"), which
                  shall be fixed in the following manner: The Company shall
                  notify the Trustee in writing of the amount of Defaulted
                  Interest proposed to be paid on each Note and the date of the
                  proposed payment (which shall not be less than 20 days after
                  such Notice is received by the Trustee), and at the same time
                  the Company shall deposit with the Trustee an amount of money
                  equal to the aggregate amount proposed to be paid in respect
                  of such Defaulted Interest or shall make arrangements
                  satisfactory to the Trustee for such deposit on or prior to
                  the date of the proposed payment, such money when deposited to
                  be held in trust for the benefit of the Persons entitled to
                  such Defaulted Interest as in this clause provided. Thereupon
                  the Trustee shall fix a Special Record Date for the payment of
                  such Defaulted Interest which shall be not more than 15 days
                  and not less than 10 days prior to the date of the proposed
                  payment and not less than 10 days after the receipt by the
                  Trustee of the Notice of the proposed payment. The Trustee
                  shall promptly notify the Company of such Special Record Date
                  and, in the name and at the expense of the Company, shall
                  cause Notice of the proposed payment of such Defaulted
                  Interest and the Special Record Date therefor to be mailed,
                  first-class postage prepaid, to each Holder of Notes at his
                  address as it appears on the list of Holders maintained
                  pursuant to this Supplemental Indenture not less than 10 days
                  prior to such Special Record Date. Notice of the proposed
                  payment of such Defaulted Interest and the Special Record Date
                  therefor having been mailed as aforesaid, such Defaulted
                  Interest shall be paid to the Persons in whose names the Notes
                  are registered at the close of business on such Special Record
                  Date and shall no longer be payable pursuant to the following
                  clause (B).

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

         Subject to the foregoing provisions of this Section 4.10, each Note
delivered under this Supplemental Indenture upon registration of transfer of or
in exchange for or in lieu of any other Note shall carry the rights to
semi-annual or contingent interest accrued and unpaid to, and to accrue, which
were carried by such other Note.

1. INTEREST

         This Note shall not bear periodic interest, except as specified in this
paragraph and in paragraphs 5 and 10 hereof. If the Principal hereof or any
portion of such Principal is not paid when due (whether upon acceleration
pursuant to the Indenture, upon the date set for payment of the Redemption Price
pursuant to paragraph 6 hereof, upon the date set for payment of a Purchase
Price pursuant to paragraph 7 hereof or upon the Final Maturity of this Note) or
if interest (including contingent interest, if any) due hereon or any portion of
such interest is not paid when due in accordance with paragraph 5 or 10 hereof,
then in each such case the overdue amount shall bear interest at the rate of
3.125% per annum, compounded semiannually (to the extent that the payment of
such interest shall be legally enforceable), which interest shall accrue from
the date such overdue amount was due to the date payment of such amount,
including interest thereon, has been made or duly provided for. All such
interest shall be payable on demand. The accrual of such interest on overdue
amounts shall be in lieu of, and not in addition to, the continued accretion.

         The Notes shall increase in Accreted Value commencing on the Issue
Date.

         "ACCRETED VALUE" means, at any date of determination, (1) prior to such
time as this Note is converted to a Cash Pay Note, the sum of (x) the Initial
Principal Amount of this Note and (y) the portion of the excess of the Principal
Amount of this Note over the Initial Principal Amount which shall have been
amortized by the Company in accordance with GAAP through such date, such amount
to be so amortized on a daily basis and compounded semi-annually on each July 20
and January 20 at the rate of 3.125% per annum from the Issue Date through the
date of determination compounded on the basis of a 360-day year and twelve
30-day months and (2) at or after such time as this Note is converted to a Cash
Pay Note, its Restated Principal Amount.

2. METHOD OF PAYMENT

         Subject to the terms and conditions of the Indenture, the Company shall
make payments in respect of the Notes to the Persons who are registered Holders
of Notes at the close of business on the Business Day preceding the Redemption
Date or Final Maturity, as the case may be, or at the close of business on a
Purchase Date. Holders must surrender Notes to a Paying Agent to collect such
payments in respect of the Notes. The Company shall pay cash amounts in money of
the United States that at the time of payment is legal tender for payment of
public and private debts. However, the Company may make such cash payments by
check payable in such money.

3. PAYING AGENT, CONVERSION AGENT, BID AGENT AND REGISTRAR

         Initially, J.P. Morgan Trust Company, National Association (the
"TRUSTEE"), shall act as Paying Agent, Conversion Agent, Bid Agent and
Registrar. The Company may appoint and

                                  Exhibit A-4
<PAGE>

change any Paying Agent, Conversion Agent, Bid Agent, Registrar or co-registrar
without Notice, other than Notice to the Trustee except that the Company will
maintain at least one Paying Agent in the State of New York, The City of New
York, Borough of Manhattan, which shall initially be an office or agency of the
Trustee. The Company or any of its Subsidiaries or any of their Affiliates may
act as Paying Agent, Conversion Agent, Bid Agent, Registrar or co registrar.

4. INDENTURE

         The Company issued the Notes under an Indenture dated as of February
12, 2001 between the Company and Trustee, as supplemented by a Supplemental
Indenture relating to the Notes between the Company and Trustee dated December
___, 2004 (together, the "INDENTURE"). The terms of the Notes include those
stated in the Indenture and those made part of the Indenture by reference to the
Trust Indenture Act of 1939 ("TIA") as in effect on the date of the Indenture.
The Notes are subject to all such terms, and Holders are referred to the
Indenture and the Act for a statement of them. Capitalized terms not defined
herein have the meanings given to those terms in the Indenture.

         The Company will furnish to any Holder upon written request and without
charge a copy of the Indenture and the applicable Authorizing Resolution or
supplemental indenture. Requests may be made to: Masco Corporation, 21001 Van
Born Road, Taylor, Michigan 48180, Attention: Corporate Secretary.

5. CONTINGENT INTEREST

         Subject to the accrual and Common Stock Record Date provisions
specified in this paragraph 5, the Company shall pay contingent interest to the
Holders during any six-month period (a "CONTINGENT INTEREST PERIOD") from
January 20 to July 19 and from July 20 to January 19, commencing January 20,
2007, if the average Note Price for the Five-Day Period with respect to such
Contingent Interest Period equals 120% or more of the Accreted Value of such
Note to the Trading Day immediately preceding the first day of the relevant
Contingent Interest Period.

         The amount of contingent interest payable per $1,000 Principal Amount
hereof in respect of any Contingent Interest Period shall equal the greater of
(x) Cash Dividends paid by the Company per share of Common Stock during that
Contingent Interest Period multiplied by the number of shares of Common Stock
equal to the sum of (A) the number of shares of Common Stock with a value equal
to the Principal Return as of the accrual date for such contingent interest and
(B) the Net Share Amount as of the accrual date for such contingent interest and
(y) 0.125% of the average Note Price for the Five-Day Period with respect to
such Contingent Interest Period.

         Contingent interest, if any, will accrue and be payable to Holders as
of the Common Stock Record Date for the related Cash Dividend or, if no Cash
Dividend is paid by the Company during a Contingent Interest Period, to Holders
as of the 15th day preceding the last day of the relevant Contingent Interest
Period. Such payments shall be paid on the payment date of the related Cash
Dividend or, if no Cash Dividend is paid by the Company during a Contingent
Interest Period, on the last day of the relevant Contingent Interest Period. In

                                  Exhibit A-5
<PAGE>

addition, on any Purchase Date or Redemption Date that occurs during a
Contingent Interest Period for which a Holder is entitled to contingent interest
pursuant to clause (y) of the preceding paragraph, contingent interest will be
payable to such Holder in an amount equal to the amount that would have been
otherwise payable to such Holder on the last day of such Contingent Interest
Period divided by the actual number of days from the first day of such
Contingent Interest Date to the Purchase Date or Redemption Date, as the case
may be, using a 360-day year composed of twelve 30-day months.

         "FIVE-DAY PERIOD" means, with respect to any Contingent Interest
Period, the five Trading Days ending on the second Trading Day immediately
preceding the first day of such Contingent Interest Period; provided, however,
if the Company shall have declared a Cash Dividend on its Common Stock that is
payable during such Contingent Interest Period but for which the Common Stock
Record Date for determining stockholders entitled thereto precedes the first day
of such Contingent Interest Period, then "FIVE-DAY PERIOD" means, with respect
to such Contingent Interest Period, the five Trading Days ending on the second
Trading Day immediately preceding such Common Stock Record Date.

         "CASH DIVIDENDS" means all cash dividends on the Common Stock (whether
regular, periodic, extraordinary, special, nonrecurring or otherwise) as
declared by the Company's Board of Directors as part of its cash dividend
payment practices.

         "NOTE PRICE" means, as of any date of determination, the average of the
secondary market bid quotations per Note obtained by the Bid Agent for $10
million Principal Amount of Notes at approximately 4:00 p.m. (New York City
time) on such determination date from three recognized securities dealers in The
City of New York (none of which shall be an Affiliate of the Company) selected
by the Company; provided, however, if (a) at least three such bids are not
obtained by the Bid Agent or (b) in the Company's reasonable judgment, the bid
quotations are not indicative of the secondary market value of the Notes as of
such determination date, then the Note Price for such determination date shall
equal (i) the Conversion Rate in effect as of such determination date multiplied
by (ii) the average Sale Price of Common Stock for the five Trading Days ending
on such determination date, appropriately adjusted to take into account the
occurrence, during the period commencing on the first of such Trading Days
during such five Trading Day period and ending on such determination date, of
any event described in Section 4.06(a), 4.06(b) or 4.06(c) (subject to the
conditions set forth in Sections 4.07(a) and 4.07(b)) of the Supplemental
Indenture.

         Upon determination that Holders will be entitled to receive contingent
interest which may become payable during a Contingent Interest Period, on or
prior to the first day of such Contingent Interest Period, the Company shall
issue a press release and publish such information on its web site at

to be purchased as of the Purchase Date, is deposited with the Paying Agent on
the Business Day immediately following the Purchase Date, such Notes will cease
to accrete and interest (including, where applicable, contingent interest), if
any, will cease to accrue on such Notes (or portions thereof) on and after such
date, and the Holder thereof shall have no other rights as such (other than the
right to receive the Purchase Price, and, where applicable, accrued and unpaid
contingent interest, if any, upon surrender or such Note).

8. NOTICE OF REDEMPTION AT THE OPTION OF THE COMPANY

         Notice of redemption at the option of the Company shall be mailed at

9. CONVERSION

         A Holder of a Note may convert this Note for the Principal Return and,
if applicable, the Net Share Amount, at any time on or before the close of
business on July 20, 2031 if at least one of the following conditions is
satisfied:

         (a) the Twenty-Day Average Price on the Conversion Date is at least a
specified percentage of the Accreted Conversion Price, such percentage beginning
at 119% for the first year and declining 1/3% on July 20 each year thereafter,
reaching 110 1/3% for the year beginning July 20, 2030 and declining to 110% at
Final Maturity;

         (b) the credit rating assigned to the Notes by either Moody's Investors
Service, Inc. or Standard & Poor's Ratings Services is reduced to below
Investment Grade;

         (c) the Notes have been called for redemption by the Company, at any
time prior to the close of business on the Business Day prior to the Redemption
Date; or

         (d) (i) the Company elects to distribute to all holders of Common Stock
rights entitling them to purchase, for a period expiring within 60 days after
the date of such distribution, Common Stock at less than the Sale Price at the
time of such distribution, (ii) the Company elects to distribute to all holders
of Common Stock assets, debt, securities or rights to purchase securities of the
Company, which distribution has a per share value as determined by the Company's
Board of Directors exceeding 15% of the Sale Price of the Common Stock on the
day preceding the declaration date for such distribution, or (iii) in the event
the Company is a party to a consolidation, merger or binding share exchange
pursuant to which the Common Stock

                                  Exhibit A-9
<PAGE>
would be converted into cash, securities or other property, at any time from and
after the date which is 15 days prior to the date the Company announces as the
anticipated effective date until 15 days after the actual effective date of such
transaction. After the effective date, settlement of the Notes and the
Conversion Value and the Net Share Amount, will be based on the kind and amount
of Cash, securities or other property of the Company or another Person that the
Holder would have received had the Holder converted its Notes immediately prior
to the transaction, unless the Company shall have elected to adjust the
Conversion Rate for a Public Acquirer Change of Control in accordance with
Section 4.02 of the Supplemental Indenture. If a Holder elects to convert Notes
in accordance with Section 4.02 of the Supplemental Indenture and is are
entitled to an adjustment for Additional Shares in accordance with Section 4.02
of the Supplemental Indenture, conversion of the Notes will settle after the
effective date of such transaction.

         In the case of the foregoing clauses (d)(i) and (ii), the Company must
notify the Holders of Notes at least 20 days prior to the Ex-Dividend Date for
such distribution. Once the Company has given such Notice, Holders may surrender
their Notes for conversion at any time thereafter until the earlier of the close
of business on the Business Day prior to the Ex-Dividend Date or the Company's
announcement that such distribution will not take place.

         In the case of the foregoing clause (d)(iii), in the event of a Change
of Control, the Company must provide the Change of Control Notice in accordance
with Section 4.02(e) of the Supplemental Indenture.

         If this Note is called for redemption, the Holder may convert it at any
time before the close of business on the last Business Day prior to the
Redemption Date. A Note in respect of which a Holder has delivered a notice of
exercise of the option to require the Company to purchase such Note may be
converted only if the notice of exercise is withdrawn in accordance with the
terms of the Indenture.

         In the event the Company exercises its option pursuant to Section 4.08
of the Supplemental Indenture to convert the Notes to Cash Pay Notes, the Holder
will be entitled on conversion to receive the Principal Amount and Net Share
Amount such Holder would have received if the Company had not exercised such
option. If the Company exercises such option, Notes surrendered for conversion
during the period from the close of business on any Regular Record Date next
preceding any Interest Payment Date to the opening of business of such Interest
Payment Date (except Notes with respect to which the Company has provided a
Notice of redemption) must be accompanied by payment of an amount equal to the
interest thereon that the registered Holder is to receive. Except where Notes
surrendered for conversion are so surrendered after a Regular Record Date but
prior to the opening of business on the corresponding Interest Payment Date (in
which case such converting Holder shall receive a final interest payment on such
Interest Payment Date, which interest payment may be repayable to the Company
upon conversion as described in this paragraph), no interest on converted Notes
will be payable by the Company on any Interest Payment Date subsequent to the
date of conversion.

         Notes surrendered for conversion during the period from the close of
business on any date on which contingent interest accrues to the opening of
business on the date on which such contingent interest is payable (except Notes
with respect to which the Company has provided a Notice of redemption) must be
accompanied by payment of an amount equal to the contingent

                                  Exhibit A-10
<PAGE>

interest with respect thereto that the registered Holder is to receive. Except
where Notes surrendered for conversion are so surrendered during the period from
the close of business on any date on which contingent interest accrues to the
opening of business on the date on which such contingent interest is payable (in
which case such converting Holder shall receive a final contingent interest
payment on the date such contingent interest is payable, which contingent
interest payment may be repayable to the Company upon conversion as described in
this paragraph), no contingent interest on converted Notes will accrue after the
date of conversion.

         To convert this Note a Holder must (1) complete and manually sign the
conversion notice on the back of this Note (or complete and manually sign a
facsimile of such notice) and deliver such notice to the Conversion Agent at the
office maintained by the Conversion Agent for such purpose, (2) surrender this
Note to the Conversion Agent, (3) furnish appropriate endorsements and transfer
documents if required by the Conversion Agent, the Company or the Trustee, (4)
pay any transfer or similar tax, if required and (5) if required, pay any
interest on the Note such Holder is to receive on the next Interest Payment Date
by virtue of having been a Holder on the relevant Regular Record Date.

         A Holder may convert a portion of this Note only if the Principal
Amount of such portion is $1,000 or a multiple of $1,000. No payment or
adjustment shall be made for dividends on the Common Stock except as provided in
the Indenture. On conversion of this Note, that portion of Accreted Value (or,
interest, if the Company has exercised its option provided for in paragraph 10
hereof) attributable to the period from the Issue Date (or, if the Company has
exercised the option referred to in paragraph 10 hereof, the later of (x) the
date of such exercise and (y) the date on which interest was last paid) to the
Conversion Date and (except as provided above) accrued contingent interest with
respect to the converted portion of this Note shall not be canceled,
extinguished or forfeited, but rather shall be deemed to be paid in full to the
Holder thereof through the delivery of the Principal Return and Net Share Amount
(together with any cash payment in lieu of fractional shares) in exchange for
the portion of this Note being converted pursuant to the terms hereof; and the
fair market value of the Principal Return and Net Share Amount, if any (together
with any Cash payment in lieu of fractional shares) shall be treated as issued,
to the extent thereof, first in exchange for Accreted Value (or interest, if the
Company has exercised its option provided for in paragraph 10 hereof) accrued
through the Conversion Date and accrued contingent interest, and the balance, if
any, of such fair market value of such Cash, Net Share Amount (and any such cash
payment) shall be treated as issued in exchange for the Initial Principal Amount
of the Note being converted pursuant to the provisions hereof.

10.      TAX EVENT

         (a) From and after (i) the date (the "TAX EVENT DATE") of the
occurrence of a Tax Event and (ii) the date the Company exercises such option,
whichever is later (the "OPTION EXERCISE DATE"), at the option of the Company,
all of the Notes will cease to accrete, and cash interest shall accrue at the
rate of 3.125% per annum on the restated principal amount (the "RESTATED
PRINCIPAL AMOUNT"), equal to the Accreted Value on the Option Exercise Date, and
shall be payable semiannually on July 20 and January 20 of each year (each an
"INTEREST PAYMENT DATE") to holders of record at the close of business on July 1
or January 1 (each a "REGULAR RECORD DATE") immediately preceding such Interest
Payment Date. Interest will be computed on the basis of a 360-day year comprised
of twelve 30-day months and will accrue

                                  Exhibit A-11
<PAGE>

from the most recent date to which interest has been paid or, if no interest has
been paid, from the Option Exercise Date.

         (b) Interest on any Note that is payable, and is punctually paid or
duly provided for, on any Interest Payment Date shall be paid to the person in
whose name that Note is registered at the close of business on the Regular
Record Date for such interest at the office or agency of the Company maintained
for such purpose. Each installment of interest on any Note shall be paid in
same-day funds by transfer to an account maintained by the payee located inside
the United States.

         (c) From and after the Option Exercise Date, contingent interest
provided for in paragraph 5 hereof shall cease to accrue on this Note.

11.      DEFAULTED INTEREST

         Except as otherwise specified with respect to the Notes, any Defaulted
Interest on any Note shall forthwith cease to be payable to the registered
Holder thereof on the relevant Regular Record Date or accrual date, as the case
may be, by virtue of having been such Holder, and such Defaulted Interest may be
paid by the Company as provided for in Section 4.10(c)(ii) of the Supplemental
Indenture.

12.      DENOMINATIONS; TRANSFER; EXCHANGE

         The Notes are in registered form, without coupons, in denominations of
$1,000 of Principal Amount and multiples of $1,000. A Holder may transfer or
convert Notes in accordance with the Indenture. The Registrar may require a
Holder, among other things, to furnish appropriate endorsements and transfer
documents and to pay any taxes and fees required by law or permitted by the
Indenture. The Registrar need not transfer or exchange any Notes selected for
redemption (except, in the case of a Note to be redeemed in part, the portion of
the Note not to be redeemed) or any Notes in respect of which a Purchase Notice
has been given and not withdrawn (except, in the case of a Note to be purchased
in part, the portion of the Note not to be purchased) or any Notes for a period
of 15 days before any selection of Notes to be redeemed.

13.      PERSONS DEEMED OWNERS

for payment unless an abandoned property law designates another person.

*The comparable yield means the annual yield the Company would pay, as of the
Issue Date, on a fixed-rate cash-pay nonconvertible debt security with no
contingent payments but with terms and conditions otherwise comparable to those
of the Notes. The schedule of projected payments is determined on the basis of
the comparable yield and an assumption of linear growth of the Company's stock
price and a constant dividend yield. The comparable yield and the schedule of
projected payments are not determined for any purpose other than for the
determination of interest accruals and adjustment thereof in respect of the
Notes for United States federal income tax purposes. The comparable yield and
the schedule of projected payments do not constitute a projection or
representation regarding the future stock price or the amounts payable on the
Notes.
