                                                 then current Exchange Ratio, as adjusted by the then current
                                                 Exchange Factor. See also "Antidilution Adjustments" below.

                                                 ("MS & Co.").

Antidilution Adjustments....................     The Exchange Factor shall be adjusted by the Calculation
                                                 Agent as follows:

                                                     1. If Home Depot Stock is subject to a stock split or
                                                 reverse stock split, then once such split has become
                                                 effective, the Exchange Factor shall be adjusted to equal
                                                 the product of the prior Exchange Factor and the number of
                                                 shares issued in such stock split or reverse stock split
                                                 with respect to one share of Home Depot Stock.

                                                     2. If Home Depot Stock is subject (i) to a stock
                                                 dividend (issuance of additional shares of Home Depot Stock)
                                                 that is given ratably to all holders of shares of Home Depot
                                                 Stock or (ii) to a distribution of Home Depot Stock as a
                                                 result of the triggering of any provision of the corporate
                                                 charter of Home Depot, then once the dividend has become
                                                 effective and Home Depot Stock is trading ex-dividend, the
                                                 Exchange Factor shall be adjusted so that the new Exchange
                                                 Factor shall equal the prior Exchange Factor plus the
                                                 product of (i) the number of shares issued with respect to
                                                 one share of Home Depot Stock and (ii) the prior Exchange
                                                 Factor.

                                                     3. There shall be no adjustments to the Exchange
                                                 Factor to reflect cash dividends or other distributions paid
                                                 with respect to Home Depot Stock other than distributions
                                                 described in clauses (i) and (v) of paragraph 5 below and
                                                 Extraordinary Dividends as described below. A cash dividend
                                                 or other distribution with respect to Home Depot Stock shall
                                                 be deemed to be an "Extraordinary Dividend" if such dividend
                                                 or other distribution exceeds the immediately preceding non-
                                                 Extraordinary Dividend for Home Depot Stock by an amount
                                                 equal to at least 10% of the Market Price of Home Depot
                                                 Stock (as adjusted for any subsequent corporate event

                                                 preceding the ex-dividend date for the payment of such
                                                 Extraordinary Dividend (the "ex-dividend date"). If an
                                                 Extraordinary Dividend occurs with respect to Home Depot
                                                 Stock, the Exchange Factor with respect to Home Depot Stock
                                                 shall be adjusted on the ex-dividend date with respect to
                                                 such Extraordinary Dividend so that the new Exchange Factor
                                                 shall equal the product of (i) the then current Exchange
                                                 Factor and (ii) a fraction, the numerator of which is the
                                                 Market Price on the Trading Day preceding the ex-dividend
                                                 date, and the denominator of which is the amount by which
                                                 the Market Price on the Trading Day preceding the
                                                 ex-dividend date exceeds the Extraordinary Dividend Amount.
                                                 The "Extraordinary Dividend Amount" with respect to an
                                                 Extraordinary Dividend for Home Depot Stock shall equal (i)
                                                 in the case of cash dividends or other distributions that
                                                 constitute regular dividends, the amount per share of such
                                                 Extraordinary Dividend minus the amount per share of the
                                                 immediately preceding non-Extraordinary Dividend for Home
                                                 Depot Stock or (ii) in the case of cash dividends or other
                                                 distributions that do not constitute regular dividends, the
                                                 amount per share of such Extraordinary Dividend. To the
                                                 extent an Extraordinary Dividend is not paid in cash, the
                                                 value of the non-cash component shall be determined by the
                                                 Calculation Agent, whose determination shall be conclusive.
                                                 A distribution on the Home Depot Stock described in clauses
                                                 (i) and (v) of paragraph 5 below that also constitutes an
                                                 Extraordinary Dividend shall cause an adjustment to the
                                                 Exchange Factor pursuant only to clause (i) or clause (v) of
                                                 paragraph 5, as applicable.

                                                     4. If Home Depot issues rights or warrants to all
                                                 holders of Home Depot Stock to subscribe for or purchase
                                                 Home Depot Stock at an exercise price per share less than
                                                 the Market Price of the Home Depot Stock on both (i) the
                                                 date the exercise price of such rights or warrants is
                                                 determined and (ii) the expiration date of such rights or
                                                 warrants, and if the expiration date of such rights or
                                                 warrants precedes the maturity of this Reset PERQS, then the
                                                 Exchange Factor shall be adjusted to equal the product of
                                                 the prior Exchange Factor and a fraction, the numerator of

                                                 shall be determined by multiplying such total number of
                                                 shares offered by the exercise price of such rights or

                                                 (collectively, the "Exchange Property") in an amount with a
                                                 value equal to the product of the final Exchange Ratio and
                                                 the Transaction Value. In addition, following a

                                                 (ii) the then current Exchange Ratio adjusted as if such
                                                 date were the next to occur of either the First Year
                                                 Determination Date or the second scheduled Trading Day prior

                                                 type of property, the holder of this Reset PERQS shall
                                                 receive at maturity a pro rata share of each such type of
                                                 Exchange Property. If Exchange Property includes a cash
                                                 component, the holder of this Reset PERQS will not receive
                                                 any interest accrued on such cash component. "Transaction

                                                 Value is determined, per share of such security multiplied
                                                 by the quantity of such security received for each share of
                                                 Home Depot Stock, as adjusted by the Exchange Factor at the
                                                 time of such Reorganization Event. In the event Exchange
                                                 Property consists of securities, those securities will, in
                                                 turn, be subject to the antidilution adjustments set forth
                                                 in paragraphs 1 through 5.

                                                 For purposes of paragraph 5 above, in the case of a
                                                 consummated tender or exchange offer or going-private
                                                 transaction involving Exchange Property of a particular
                                                 type, Exchange Property shall be deemed to include the
                                                 amount of cash or other property paid by the offer or in the
                                                 tender or exchange offer with respect to such Exchange
                                                 Property (in an amount determined on the basis of the rate
                                                 of exchange in such tender or exchange offer or a
                                                 going-private transaction). In the event of a tender or
                                                 exchange offer or going-private transaction with respect to
                                                 Exchange Property in which an offeree may elect to receive
                                                 cash or other property, Exchange Property shall be deemed to
                                                 include the kind and amount of cash and other property
                                                 received by offerees who elect to receive cash.

                                                 No adjustments to the Exchange Factor shall be required
                                                 unless such adjustment would require a change of at least
                                                 0.1% in the Exchange Factor then in effect. The Exchange
                                                 Factor resulting from any of the adjustments specified above
                                                 will be rounded to the nearest one hundred-thousandth with
                                                 five one-millionths being rounded upward.

                                                 No adjustments to the Exchange Factor or method of
                                                 calculating the Exchange Ratio shall be made other than
                                                 those specified above.

                                                 Notwithstanding the foregoing, the amount payable by the
                                                 Issuer at maturity with respect to this Reset PERQS,

its successors and assigns, the "Issuer"), for value received, hereby promises

(or other Exchange Property), as determined in accordance with the provisions
set forth under "Exchange at Maturity" above, due with respect to
the principal sum of U.S.$                          (UNITED STATES
DOLLARS                     ) on the Maturity Date specified above (except to
     the extent redeemed or repaid prior to maturity) and to pay interest
thereon at the Interest Rate per annum specified above, from and including the
Interest Accrual Date specified above until the principal hereof is paid or
duly made available for payment weekly, monthly, quarterly, semiannually or
annually in arrears as specified above as the Interest Payment Period on each
Interest Payment Date (as specified above), commencing on the Interest Payment
Date next succeeding the Interest Accrual Date specified above, and at maturity
(or on any redemption or repayment date); provided, however, that if the
Interest Accrual Date occurs between a Record Date, as defined below, and the
next succeeding Interest Payment Date, interest payments will commence on the
second Interest Payment Date succeeding the Interest Accrual Date to the
registered holder of this Note on the Record Date with respect to such second
Interest Payment Date; and provided, further, that if this Note is subject to
"Annual Interest Payments," interest payments shall be made annually in arrears
and the term "Interest Payment Date" shall be deemed to mean the first day of
March in each year.

         Interest on this Note will accrue from and including the most recent
date to which interest has been paid or duly provided for, or, if no interest
has been paid or duly provided for, from and including the Interest Accrual
Date, until, but excluding the date the principal hereof has been paid or duly
made available for payment. The interest so payable, and punctually paid or
duly provided for, on any Interest Payment Date will, subject to certain
exceptions described herein, be paid to the person in whose name this Note (or
one or more predecessor Notes) is registered at the close of business on the
date 15 calendar days prior to such Interest Payment Date (whether or not a
Business Day (as defined below)) (each such date a "Record Date"); provided,
however, that interest payable at maturity (or any redemption or repayment
date) will be payable to the person to whom the principal hereof shall be
payable. As used herein, "Business Day" means any day, other than a Saturday or
Sunday, (a) that is neither a legal holiday nor a day on which banking
institutions are authorized or required by law or regulation to close (x) in
The City of New York or (y) if this Note is denominated in a Specified Currency
other than U.S. dollars, Australian dollars or euro, in the principal financial
center of the country of the Specified Currency, or (z) if this Note is

denominated in euro, that is also a day on which the Trans-European Automated
Real-time Gross Settlement Express Transfer System ("TARGET") is operating (a
"TARGET Settlement Day").

         Payment of the principal of this Note, any premium and the interest
due at maturity (or any redemption or repayment date), unless this Note is
denominated in a Specified Currency other than U.S. dollars and is to be paid
in whole or in part in such Specified Currency, will be made in immediately
available funds upon surrender of this Note at the office or agency of the
Paying Agent, as defined on the reverse hereof, maintained for that purpose in
the Borough of Manhattan, The City of New York, or at such other paying agency
as the Issuer may determine, in U.S. dollars. U.S. dollar payments of interest,
other than interest due at maturity or on any date of redemption or

                                      A-16

repayment, will be made by U.S. dollar check mailed to the address of the
person entitled thereto as such address shall appear in the Note register. A
holder of U.S. $10,000,000 (or the equivalent in a Specified Currency) or more
in aggregate principal amount of Notes having the same Interest Payment Date,
the interest on which is payable in U.S. dollars, shall be entitled to receive
payments of interest, other than interest due at maturity or on any date of
redemption or repayment, by wire transfer of immediately available funds if
appropriate wire transfer instructions have been received by the Paying Agent
in writing not less than 15 calendar days prior to the applicable Interest
Payment Date.

         If this Note is denominated in a Specified Currency other than U.S.
dollars, and the holder does not elect (in whole or in part) to receive payment
in U.S. dollars pursuant to the next succeeding paragraph, payments of
interest, principal or any premium with regard to this Note will be made by
wire transfer of immediately available funds to an account maintained by the
holder hereof with a bank located outside the United States if appropriate wire
transfer instructions have been received by the Paying Agent in writing, with
respect to payments of interest, on or prior to the fifth Business Day after
the applicable Record Date and, with respect to payments of principal or any
premium, at least ten Business Days prior to the Maturity Date or any
redemption or repayment date, as the case may be; provided that, if payment of
interest, principal or any premium with regard to this Note is payable in euro,
the account must be a euro account in a country for which the euro is the
lawful currency, provided, further, that if such wire transfer instructions are
not received, such payments will be made by check payable in such Specified
Currency mailed to the address of the person entitled thereto as such address
shall appear in the Note register; and provided, further, that payment of the
principal of this Note, any premium and the interest due at maturity (or on any
redemption or repayment date) will be made upon surrender of this Note at the
office or agency referred to in the preceding paragraph.

         If so indicated on the face hereof, the holder of this Note, if
denominated in a Specified Currency other than U.S. dollars, may elect to
receive all or a portion of payments on this Note in U.S. dollars by
transmitting a written request to the Paying Agent, on or prior to the fifth
Business Day after such Record Date or at least ten Business Days prior to the
Maturity Date or any redemption or repayment date, as the case may be. Such
election shall remain in effect unless such request is revoked by written
notice to the Paying Agent as to all or a portion of payments on this Note at
least five Business Days prior to such Record Date, for payments of interest,
or at least ten days prior to the Maturity Date or any redemption or repayment
date, for payments of principal, as the case may be.

         If the holder elects to receive all or a portion of payments of
principal of and any premium and interest on this Note, if denominated in a
Specified Currency other than U.S. dollars, in U.S. dollars, the Exchange Rate
Agent (as defined on the reverse hereof) will convert such payments into U.S.
dollars. In the event of such an election, payment in respect of this Note will
be based upon the exchange rate as determined by the Exchange Rate Agent based
on the highest bid quotation in The City of New York received by such Exchange
Rate Agent at approximately 11:00 a.m., New York City time, on the second
Business Day preceding the applicable payment date from three recognized
foreign exchange dealers (one of which may be the Exchange Rate Agent unless
such

                                      A-17

Exchange Rate Agent is an affiliate of the Issuer) for the purchase by the
quoting dealer of U.S. dollars for the Specified Currency for settlement on
such payment date in the amount of the Specified Currency payable in the
absence of such an election to such holder and at which the applicable dealer
commits to execute a contract. If such bid quotations are not available, such
payment will be made in the Specified Currency. All currency exchange costs
will be borne by the holder of this Note by deductions from such payments.

         Reference is hereby made to the further provisions of this Note set
forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

         Unless the certificate of authentication hereon has been executed by
the Trustee referred to on the reverse hereof by manual signature, this Note
shall not be entitled to any benefit under the Senior Indenture, as defined on
the reverse hereof, or be valid or obligatory for any purpose.

Amended and Restated Senior Indenture, dated as of May 1, 1999, between the
Issuer and The Chase Manhattan Bank, as Trustee (the "Trustee," which term

Indenture and all indentures supplemental thereto reference is hereby made for
a statement of the respective rights, limitations of rights, duties and
immunities of the Issuer, the Trustee and holders of the Notes and the terms
upon which the Notes are, and are to be, authenticated and delivered. The
Issuer has appointed The Chase Manhattan Bank at its corporate trust office in
The City of New York as the paying agent (the "Paying Agent," which term
includes any additional or successor Paying Agent appointed by the Issuer) with
respect to the Notes. The terms of individual Notes may vary with respect to
interest rates, interest rate formulas, issue dates, maturity dates, or
otherwise, all as provided in the Senior Indenture. To the extent not
inconsistent herewith, the terms of the Senior Indenture are hereby
incorporated by reference herein.

         Unless otherwise indicated on the face hereof, this Note will not be
subject to any sinking fund and, unless otherwise provided on the face hereof
in accordance with the provisions of the following two paragraphs, will not be

         If so indicated on the face hereof, this Note may be redeemed in whole
or in part at the option of the Issuer on or after the Initial Redemption Date
specified on the face hereof on the terms set forth on the face hereof,
together with interest accrued and unpaid hereon to the date of redemption. If
this Note is subject to "Annual Redemption Percentage Reduction," the Initial
Redemption Percentage indicated on the face hereof will be reduced on each
anniversary of the Initial Redemption Date by the Annual Redemption Percentage
Reduction specified on the face hereof until the redemption price of this Note
is 100% of the principal amount hereof, together with interest accrued and
unpaid hereon to the date of redemption. Notice of redemption shall be mailed
to the registered holders of the Notes designated for redemption at their
addresses as the same shall appear on the Note register not less than 30 nor
more than 60 days prior to the date fixed for redemption or within the
Redemption Notice Period specified on the face hereof, subject to all the
conditions and provisions of the Senior Indenture. In the event of redemption

Repayment Date, this Note will be repayable in whole or in part in increments

authorized denomination hereof) at the option of the holder hereof at a price
equal to 100% of the principal amount to be repaid, together with interest

                                      A-20

Note with the form entitled "Option to Elect Repayment" below duly completed or

certificate number of this Note or a description of this Note's tenor and
terms, the principal amount hereof to be repaid, a statement that the option to
elect repayment is being exercised thereby and a guarantee that this Note,
together with the form entitled "Option to Elect Repayment" duly completed,
will be received by the Paying Agent not later than the fifth Business Day
after the date of such telegram, telex, facsimile transmission or letter;
provided, that such telegram, telex, facsimile transmission or letter shall

any redemption or repayment date) does not fall on a Business Day, payment of
interest, premium, if any, or principal otherwise payable on such date need not
be made on such date, but may be made on the next succeeding Business Day with
the same force and effect as if made on the Interest Payment Date or on the
Maturity Date (or any redemption or repayment date), and no interest on such
payment shall accrue for the period from and after the Interest Payment Date or
the Maturity Date (or any redemption or repayment date) to such next succeeding
Business Day.

Trustee and duly executed by the registered holder hereof in person or by the
holder's attorney duly authorized in writing, and thereupon the Trustee shall
issue in the name of the transferee or transferees, in exchange herefor, a new
Note or Notes having identical terms and provisions and having a like aggregate
principal amount in authorized denominations, subject to the terms and
conditions set forth herein; provided, however, that the Trustee will not be
required (i) to register the transfer of or exchange any Note that has been
called for redemption in whole or in part, except the unredeemed portion of
Notes being redeemed in part, (ii) to register the transfer of or exchange any
Note if the holder thereof has exercised his right, if any, to require the
Issuer to repurchase such Note in whole or in part, except the portion of such
Note not required to be repurchased, or (iii) to register the transfer of or
exchange Notes to the extent and during the period so provided in the Senior
Indenture with respect to the redemption of Notes. Notes are exchangeable at
said office for other Notes of other authorized denominations of equal
aggregate principal amount having identical terms and provisions. All such
exchanges and transfers of Notes will be free of charge, but the Issuer may
require payment of a sum sufficient to cover any tax or other governmental
charge in connection therewith. All Notes surrendered for exchange shall be
accompanied by a written instrument of transfer in form satisfactory to the
Trustee and executed by the registered holder in person or by the holder's
attorney duly authorized in writing. The date of registration of any Note
delivered upon any exchange or transfer of Notes shall be such that no gain or
loss of interest results from such exchange or transfer.

         In case this Note shall at any time become mutilated, defaced or be
destroyed, lost or stolen and this Note or evidence of the loss, theft or
destruction thereof (together with the indemnity hereinafter referred to and
such other documents or proof as may be required in the premises) shall be
delivered to the Trustee, the Issuer in its discretion may execute a new Note
of like tenor in exchange for this Note, but, if this Note is destroyed, lost
or stolen, only upon receipt of evidence satisfactory to the Trustee and the
Issuer that this Note was destroyed or lost or stolen and, if required, upon
receipt also of indemnity satisfactory to each of them. All expenses and
reasonable charges associated with procuring such indemnity and with the
preparation, authentication and delivery of a new Note shall be borne by the
owner of the Note mutilated, defaced, destroyed, lost or stolen.

         The Senior Indenture provides that (a) if an Event of Default (as
defined in the Senior Indenture) due to the default in payment of principal of,
premium, if any, or interest on, any series of debt securities issued under the
Senior Indenture, including the series of Senior Medium-Term Notes of which
this Note forms a part, or due to the default in the performance or breach of
any other covenant or warranty of the Issuer applicable to the debt securities
of such series but not applicable to all outstanding debt securities issued
under the Senior Indenture shall have occurred

                                      A-22

<PAGE>

and be continuing, either the Trustee or the holders of not less than 25% in
principal amount of the debt securities of each affected series (voting as a
single class) may then declare the principal of all debt securities of all such
series and interest accrued thereon to be due and payable immediately and (b)
if an Event of Default due to a default in the performance of any other of the
covenants or agreements in the Senior Indenture applicable to all outstanding
debt securities issued thereunder, including this Note, or due to certain
events of bankruptcy or insolvency of the Issuer, shall have occurred and be
continuing, either the Trustee or the holders of not less than 25% in principal
amount of all debt securities issued under the Senior Indenture then
outstanding (treated as one class) may declare the principal of all such debt
securities and interest accrued thereon to be due and payable immediately, but
upon certain conditions such declarations may be annulled and past defaults may
be waived (except a continuing default in payment of principal (or premium, if
any) or interest on such debt securities) by the holders of a majority in
principal amount of the debt securities of all affected series then
outstanding.

         If the face hereof indicates that this Note is subject to "Modified
Payment upon Acceleration," then (i) if the principal hereof is declared to be
due and payable as described in the preceding paragraph, the amount of
principal due and payable with respect to this Note shall be limited to the
aggregate principal amount hereof multiplied by the sum of the Issue Price
specified on the face hereof (expressed as a percentage of the aggregate
principal amount) plus the original issue discount amortized from the Interest
Accrual Date to the date of declaration, which amortization shall be calculated
using the "interest method" (computed in accordance with generally accepted
accounting principles in effect on the date of declaration), (ii) for the
purpose of any vote of securityholders taken pursuant to the Senior Indenture
prior to the acceleration of payment of this Note, the principal amount hereof
shall equal the amount that would be due and payable hereon, calculated as set
forth in clause (i) above, if this Note were declared to be due and payable on
the date of any such vote and (iii) for the purpose of any vote of
securityholders taken pursuant to the Senior Indenture following the
acceleration of payment of this Note, the principal amount hereof shall equal
the amount of principal due and payable with respect to this Note, calculated
as set forth in clause (i) above.

         The Senior Indenture permits the Issuer and the Trustee, with the
consent of the holders of not less than a majority in aggregate principal
amount of the debt securities of all series issued under the Senior Indenture
then outstanding and affected (voting as one class), to execute supplemental
indentures adding any provisions to or changing in any manner the rights of the
holders of each series so affected; provided that the Issuer and the Trustee
may not, without the consent of the holder of each outstanding debt security
affected thereby, (a) extend the final maturity of any such debt security, or
reduce the principal amount thereof, or reduce the rate or extend the time of
payment of interest thereon, or reduce any amount payable on redemption or
repayment thereof, or change the currency of payment thereof, or modify or
amend the provisions for conversion of any currency into any other currency, or
modify or amend the provisions for conversion or exchange of the debt security
for securities of the Issuer or other entities (other than as provided in the
antidilution provisions or other similar adjustment provisions of the debt
securities or otherwise in accordance with the terms thereof), or impair or
affect the rights of any holder to institute suit for the payment thereof
without the consent of the holder of each debt security so affected or (b)
reduce the aforesaid

                                      A-23

<PAGE>

percentage in principal amount of debt securities the consent of the holders of
which is required for any such supplemental indenture.

         Except as set forth below, if the principal of, premium, if any, or
interest on, this Note is payable in a Specified Currency other than U.S.
dollars and such Specified Currency is not available to the Issuer for making
payments hereon due to the imposition of exchange controls or other
circumstances beyond the control of the Issuer or is no longer used by the
government of the country issuing such currency or for the settlement of
transactions by public institutions within the international banking community,
then the Issuer will be entitled to satisfy its obligations to the holder of
this Note by making such payments in U.S. dollars on the basis of the Market
Exchange Rate on the date of such payment or, if the Market Exchange Rate is
not available on such date, as of the most recent practicable date; provided,
however, that if the euro has been substituted for such Specified Currency, the
Issuer may at its option (or shall, if so required by applicable law) without
the consent of the holder of this Note effect the payment of principal of,
premium, if any, or interest on, any Note denominated in such Specified
Currency in euro in lieu of such Specified Currency in conformity with legally
applicable measures taken pursuant to, or by virtue of, the treaty establishing
the European Community (the "EC"), as amended by the treaty on European Union
(as so amended, the "Treaty"). Any payment made under such circumstances in
U.S. dollars or euro where the required payment is in an unavailable Specified
Currency will not constitute an Event of Default. If such Market Exchange Rate
is not then available to the Issuer or is not published for a particular
Specified Currency, the Market Exchange Rate will be based on the highest bid
quotation in The City of New York received by the Exchange Rate Agent at
approximately 11:00 a.m., New York City time, on the second Business Day
preceding the date of such payment from three recognized foreign exchange
dealers (the "Exchange Dealers") for the purchase by the quoting Exchange
Dealer of the Specified Currency for U.S. dollars for settlement on the payment
date, in the aggregate amount of the Specified Currency payable to those
holders or beneficial owners of Notes and at which the applicable Exchange
Dealer commits to execute a contract. One of the Exchange Dealers providing
quotations may be the Exchange Rate Agent unless the Exchange Rate Agent is an
affiliate of the Issuer. If those bid quotations are not available, the
Exchange Rate Agent shall determine the market exchange rate at its sole
discretion.

         The "Exchange Rate Agent" shall be Morgan Stanley & Co. Incorporated,
unless otherwise indicated on the face hereof.

         All determinations referred to above made by, or on behalf of, the
Issuer or by, or on behalf of, the Exchange Rate Agent shall be at such
entity's sole discretion and shall, in the absence of manifest error, be
conclusive for all purposes and binding on holders of Notes and coupons.

         So long as this Note shall be outstanding, the Issuer will cause to be
maintained an office or agency for the payment of the principal of and premium,
if any, and interest on this Note as herein provided in the Borough of
Manhattan, The City of New York, and an office or agency in said Borough of
Manhattan for the registration, transfer and exchange as aforesaid of the
Notes. The Issuer may designate other agencies for the payment of said
principal, premium and interest at such place or places (subject to applicable
laws and regulations) as the Issuer may decide. So long as

                                      A-24

<PAGE>

there shall be such an agency, the Issuer shall keep the Trustee advised of the
names and locations of such agencies, if any are so designated.

         With respect to moneys paid by the Issuer and held by the Trustee or
any Paying Agent for payment of the principal of or interest or premium, if
any, on any Notes that remain unclaimed at the end of two years after such
principal, interest or premium shall have become due and payable (whether at
maturity or upon call for redemption or otherwise), (i) the Trustee or such
Paying Agent shall notify the holders of such Notes that such moneys shall be
repaid to the Issuer and any person claiming such moneys shall thereafter look
only to the Issuer for payment thereof and (ii) such moneys shall be so repaid
to the Issuer. Upon such repayment all liability of the Trustee or such Paying
Agent with respect to such moneys shall thereupon cease, without, however,
limiting in any way any obligation that the Issuer may have to pay the
principal of or interest or premium, if any, on this Note as the same shall
become due.

         No provision of this Note or of the Senior Indenture shall alter or
impair the obligation of the Issuer, which is absolute and unconditional, to
pay the principal of, premium, if any, and interest on this Note at the time,
place, and rate, and in the coin or currency, herein prescribed unless
otherwise agreed between the Issuer and the registered holder of this Note.

         Prior to due presentment of this Note for registration of transfer,
the Issuer, the Trustee and any agent of the Issuer or the Trustee may treat
the holder in whose name this Note is registered as the owner hereof for all
purposes, whether or not this Note be overdue, and none of the Issuer, the
Trustee or any such agent shall be affected by notice to the contrary.

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

         This Note shall for all purposes be governed by, and construed in
accordance with, the laws of the State of New York.

         All terms used in this Note which are defined in the Senior Indenture
and not otherwise defined herein shall have the meanings assigned to them in
the Senior Indenture.
