6.625% Senior Note Due July 15, 2012

      UST INC., a corporation duly organized and existing under the laws of Delaware (herein called the “Company”, which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to Cede & Co., or registered assigns, the principal sum of Five Hundred Million Dollars on July 15, 2012, and to pay interest thereon from July 15, 2002, or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually on January 15 and July 15 in each year, commencing January 15, 2003, at the rate of 6.625% per annum, until the principal hereof is paid or made available for payment; provided, however, that if (i) the Company has not filed a registration statement (the “Exchange Registration Statement”) under the Securities Act of 1933, as amended (the “Securities Act”), registering a security substantially identical to this Security (except that such Security will not contain terms with respect to the Special Interest payments described below or transfer restrictions) pursuant to an exchange offer (the “Exchange Offer”) within 120 days after the Securities are initially issued (or, in lieu thereof if such obligation arises pursuant to the Indenture, a registration statement registering this Security for resale (a “Resale Registration Statement”) within 30 days after the time such obligation arises), or (ii) the Exchange Registration Statement relating to the Exchange Offer has not become or been declared effective within 180 days after the Securities are initially issued (or, if applicable, the Resale Registration Statement has not become or been declared effective within 120 days after filing), or (iii) the Exchange Offer has not been completed within 210 days after the securities are initially issued (if the Exchange Offer is then required to be made pursuant to the Exchange and Registration Rights Agreement (the “Exchange and Registration Rights Agreement”), dated as of July 15, 2002, by and between the Company, the Purchasers (as defined therein) and the Holders from time to time of the Securities) or (iv) either the Exchange Registration Statement or, if applicable, the Resale Registration Statement is filed and declared effective (except as specifically permitted therein) but shall thereafter cease to be effective without being succeeded promptly by an additional registration statement filed and declared effective, in each case (i) through (iv) upon the terms and conditions set forth in the Exchange and Registration Rights Agreement (each such event referred to in clauses (i) through (iv), a “Registration Default”), then special interest (“Special Interest”) will accrue (in addition to the stated interest on the Securities) at a per annum rate of 0.25% for the first 90 days, determined daily, on the principal amount of the Securities, for the period from the occurrence of the Registration Default until such time as no Registration Default is in effect and, provided, further, that if either the Exchange Offer has not been consummated or, if applicable, the Resale Registration Statement has not become or been declared effective, in each case within this first 90 days, then the per annum rate of such Special Interest shall increase by an additional 0.25% per annum for each subsequent 90-day period (provided that the rate of Special Interest shall not exceed 1.0% per annum in the aggregate) and Special Interest will be payable at such increased rate until such time as the Company consummates the Exchange Offer or, if applicable, the Resale Registration Statement becomes or has been declared effective (after which such interest rate will be restored to its initial rate). Interest accruing as a result of Registration Default (which shall be computed on the basis of a 365-day year) is referred to herein as “Special Interest.” Accrued Special Interest, if any, shall be paid semi-annually on January 1 and July 1, in each year; and the amount of accrued Special Interest shall be determined on the basis of the number of days actually elapsed. Any accrued and unpaid interest (including Special Interest) on this Security upon the issuance of an Exchange Security (as defined in the Indenture) in exchange for this Security shall cease to be payable to the Holder hereof but such accrued and unpaid interest (including Special Interest) shall be payable on the next Interest Payment Date for such Exchange Security to the Holder thereof on the related Regular Record Date.

      The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, which shall be the January 1 or July 1 (whether or not a Business Day), as the case may be, next preceding such Interest Payment Date.

[Reverse of Security ]

      This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Indenture, dated as of May 27, 1999 (herein called the “Indenture”, which term shall have the meaning assigned to it in such instrument), between the Company and State Street Bank and Trust Company, as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof, limited in aggregate principal amount to $600,000,000.

      The Securities may be redeemed, in whole or from time to time in part, at the option of the Company at a redemption price equal to the greater of:

plus, in the case of both clause (1) and clause (2) above, accrued and unpaid interest on the principal amount of the Securities being redeemed to that redemption date. Notwithstanding the foregoing, payments of interest on the Securities that are due and payable on or prior to a date fixed for redemption of the Securities will be payable to the holders of those Securities registered as such at the close of business on the relevant record dates according to the terms of the Securities and the terms and provisions of the Indenture.

      “Treasury Rate” means, with respect to any redemption date for the Securities,

The Treasury Rate shall be calculated on the third Business Day preceding the applicable redemption date. As used in the immediately preceding sentence and in the definition of “Reference Treasury Dealer Quotations” below, the term “Business Day” means each Monday, Tuesday, Wednesday, Thursday and Friday that is not a day on which banking institutions in The City of New York are authorized or obligated by law, regulation or executive order to close.

      “Comparable Treasury Issue” means, with respect to any redemption date for the Securities, the United States Treasury security selected by the Independent Investment Banker as having a maturity comparable to the remaining term of the Securities to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Securities to be redeemed.

5

      “Comparable Treasury Price” means, with respect to any redemption date for the Securities, (1) the average of four Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (2) if the Trustee obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations.

      “Final Maturity Date” means July 15, 2012.

      “Independent Investment Banker” means, with respect to any redemption date for the Securities, Morgan Stanley & Co. Incorporated and its successors or Goldman, Sachs & Co. and its successors, whichever shall be selected by the Trustee after consultation with the Company, or, if both such firms or the respective successors, if any, to such firms, as the case may be, are unwilling or unable to select the Comparable Treasury Issue, an independent investment banking institution of national standing appointed by the Trustee after consultation with the Company.

      “Reference Treasury Dealers” means, with respect to any redemption date for the Securities, Goldman, Sachs & Co. and Morgan Stanley & Co. Incorporated and their respective successors (provided, however, that if any such firm or any such successor, as the case may be, shall cease to be a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), the Trustee, after consultation with the Company, shall substitute therefor another Primary Treasury Dealer), and two other Primary Treasury Dealers selected by the Trustee after consultation with the Company.

      “Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date for the Securities, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by that Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding that redemption date.

      Notice of any redemption will be mailed at least 30 days but not more than 60 days before the redemption date to each holder of the Securities to be redeemed at the holder’s registered address. If less than all of the Securities are to be redeemed at the Company’s option, the Trustee will select, in a manner it deems fair and appropriate, the Securities, or portions of the Securities, to be redeemed.

      Unless the Company defaults in payment of the redemption price due in respect of the Securities on any redemption date, on and after the redemption date, interest will cease to accrue on the Securities or portions of the Securities called for redemption on that redemption date.

      In the event of redemption of this Security in part only, a new Security or Securities of this series and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.

      The Securities do not have the benefit of any sinking fund obligations.

      The Indenture contains provisions for defeasance at any time of the entire indebtedness of this Security or certain restrictive covenants and Events of Default with respect to this Security, in each case upon compliance with certain conditions set forth in the Indenture.

      If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

      The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of 66 2/3% in principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or

      As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or Trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount of the Securities of this series at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee shall not have received from the Holders of a majority in principal amount of Securities of this series at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein.

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

      As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of and any premium and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

      The Securities of this series are issuable only in registered form without coupons in denominations of $1000 and any integral multiple thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

      No service charge shall be made to a Holder for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

      Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

      All terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture.
