REVERSE OF SECURITY

The Home Depot, Inc.

Floating Rate Senior Note due December 16, 2009

This Security is one of a duly authorized issue of debt securities of the Company, issued or to be issued in one or more series pursuant to an indenture dated as of May 4, 2005 (the “Indenture”), duly executed and delivered by the Company to The Bank of New York Trust Company, N.A., as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture). Reference is hereby made to the Indenture and all indentures supplemental thereto for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the holders (the words “holders” or “holder” meaning the registered holders or registered holder) of the Securities of this series.

This Security will bear interest from December 19, 2006 or from the most recent interest payment date on which the Company has paid or provided for interest on the Security. The interest rate per annum will be reset quarterly on the first day of each “interest period” (defined below) and will be equal to LIBOR (as defined below) plus 0.125% as determined by the calculation agent. The Security will bear interest until final Maturity at a “daily interest amount” which will be calculated by dividing the interest rate in effect for that day by 360 and multiplying the result by the principal amount of the Security. The amount of interest to be paid on the Security for each interest period will be calculated by adding the daily interest amounts for each day in the interest period. The Company will pay interest on overdue principal of, premium, if any, and to the extent lawful, interest on overdue installments of interest, at the same rate. If any Interest Payment Date would fall on a day that is not a Business Day (other than an Interest Payment Date that is also the Maturity), that Interest Payment Date will be postponed to the following day that is a Business Day, except that if such next Business Day is in a different month, then that payment date will be the immediately preceding day that is a Business Day. If the Maturity for the Security is not a Business Day, payment of principal and interest will be made on the following day that is a Business Day and no interest will accrue for the period from and after such Maturity.

In case an Event of Default, as defined in the Indenture, shall have occurred and be continuing with respect to this series of Securities, the principal of all the outstanding Securities of this series may be declared due and payable, in the manner and with the effect, and subject to the conditions, provided in the Indenture. The Indenture provides that in certain events such declaration and its consequences may be waived by the holders of a majority in aggregate Principal Amount of the Securities of this series then outstanding and that, prior to any such declaration, such holders may waive any past default under the Indenture and its consequences except a default in the payment of principal of, premium, if any, or

(Face of Global Security continued on next page)

interest on any of the Securities of this series. Any such consent or waiver by the holder of this Security (unless revoked as provided in the Indenture) shall be conclusive and binding upon such holder and upon all future holders and owners of this Security and any Security of this series which may be issued in exchange or substitution herefor, whether or not any notation thereof is made upon this Security or such other Securities of this series.

The Indenture permits, with certain exceptions as therein provided, the Company and the Trustee, with the consent of the holders of at least a majority in aggregate Principal Amount of the Securities at the time outstanding, evidenced as provided in the Indenture, to execute supplemental indentures adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or modifying in any manner the rights of the holders of the Securities.

Notwithstanding the foregoing, without the consent of any holder of Securities of this series, the Company and the Trustee may amend or supplement the Indenture or the Securities of this series to cure any ambiguity, defect or inconsistency to provide for uncertificated Securities of this series in addition to or in place of certificated Securities of this series, to provide for the assumption of the Company’s obligations to holders of Securities of this series in the case of a transaction described in Section 10.01 of the Indenture, to evidence and provide for the acceptance of appointment by a successor trustee and to add to or change any of the provisions of the Indenture necessary to provide for or facilitate the administration of the trusts by more than one trustee, to make any change that would provide any additional rights or benefits to the holders of Securities of this series or that does not adversely affect the legal rights under the Indenture of any such holder, or to comply with requirements of the Commission in order to maintain the qualification of the Indenture under the Trust Indenture Act.

No reference herein to the Indenture and no provision of this Security shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of, premium, if any, and interest on this Security at the place, times, and rate, and in the currency, herein prescribed.

The Securities of this series are issuable only as registered Securities without coupons in denominations of $2,000 and any multiple of $1,000.

At the office or agency of the Company referred to on the face hereof and in the manner and subject to the limitations provided in the Indenture and this Security, Securities of this series may be exchanged for a like aggregate principal amount of Securities of this series of other authorized denominations.

Upon due presentment for registration of transfer of this Security at the above-mentioned office or agency of the Company, a new Security or Securities of this series of authorized denominations, for a like aggregate principal amount, will be issued to the transferee as provided in the Indenture. No service charge

shall be made for any such transfer, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto.

The Securities of this series are redeemable in whole or in part, at the option of the Company at any time and from time to time, after June 16, 2008 and prior to the maturity of the Securities, on not less than 30 or more than 60 days’ prior notice mailed to the holders of the Securities, at a redemption price equal to 100% of the principal amount of such notes, plus any accrued and unpaid interest thereon to the date of redemption.

“LIBOR,” with respect to an interest period, shall be the rate (expressed as a percentage per annum) for deposits in United States dollars for a three-month period beginning on the second London Banking Day after the Determination Date (as defined below) that appears on Telerate Page 3750 (as defined below) as of 11:00 a.m., London time, on the Determination Date. If Telerate Page 3750 does not include this rate or is unavailable on the Determination Date, the calculation agent will obtain such rate from Bloomberg’s page “BBAM.” If neither Telerate Page 3750 nor Bloomberg L.P. page “BBAM” includes such rate, the calculation agent will request the principal London office of each of four major banks in the London interbank market, as selected by the calculation agent (in consultation with us), to provide that bank’s offered quotation (expressed as a percentage per annum) as of approximately 11:00 a.m., London time, on the Determination Date to prime banks in the London interbank market for deposits in a Representative Amount (as defined below) in United States dollars for a three-month period beginning on the second London Banking Day after the Determination Date. If at least two offered quotations are so provided, LIBOR for the interest period will be the arithmetic mean of those quotations. If fewer than two quotations are so provided, the calculation agent will request each of three major banks in New York City, as selected by the calculation agent, to provide that bank’s rate (expressed as a percentage per annum), as of approximately 11:00 a.m., New York City time, on the Determination Date for loans in a Representative Amount in United States dollars to leading European banks for a three-month period beginning on the second London Banking Day after the Determination Date. If at least two rates are so provided, LIBOR for the interest period will be the arithmetic mean of those rates. If fewer than two rates are so provided, then LIBOR for the interest period will be LIBOR in effect with respect to the immediately preceding interest period.

“Determination Date” with respect to an interest period will be the second London Banking Day preceding the first day of the interest period.

“London Banking Day” is any day in which dealings in United States dollars are transacted or, with respect to any future date, are expected to be transacted in the London interbank market.

If the Company is redeeming less than all the Securities, the Trustee must select the Securities to be redeemed by such method as the Trustee deems fair and appropriate in accordance with methods generally used at the time of selection by fiduciaries in similar circumstances. Subject to payment by the Company of a sum sufficient to pay the amount due on redemption, interest on this Security (or portion hereof if this Security is redeemed in part) shall cease to accrue upon the date duly fixed for redemption of this Security (or portion hereof if this Security is redeemed in part). In the event of redemption of this Security in part only, a new Security or Securities of this series for the unredeemed portion hereof will be issued in the name of the holder hereof upon the cancellation hereof.

If a Change of Control Triggering Event (as defined below) occurs, unless the Company has exercised its right to redeem the Securities as described above, holders of Securities will have the right to require the Company to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of their Securities pursuant to the offer described below (the “Change of Control Offer”).
