Dear Stockholder:

     You recently received the 2004 UST Inc. Annual Report and 2005 Proxy materials. Unfortunately, we have discovered that the Proxy materials sent to some of our stockholders included defective proxy cards. These cards inadvertently omitted a box entitled “Abstain” with respect to Stockholder Proposal No. 4, which relates to the way the Company promotes its tobacco products on the internet.

     In order to ensure that you have been provided a complete set of accurate Proxy material, we have enclosed a corrected proxy card along with another copy of the 2004 UST Inc. Annual Report and 2005 Proxy. If you have not yet voted your 2005 Proxy and wish to vote by mail or if you have voted by mail and wish to change your vote by mail, you should use the enclosed, revised proxy card and return it promptly in the enclosed postage paid envelope. In addition, if you wish to vote by mail and abstain with regard to Stockholder Proposal No. 4, you must use the enclosed, revised proxy card. If you have voted your 2005 Proxy by internet or by telephone or you have already voted by mail and do not wish to change your vote, you may disregard this notice.

     We apologize for any inconvenience this error may have caused. If you have any questions regarding voting your 2005 Proxy, please refer to the enclosed Proxy materials. If you require further assistance, please call the Inspector of Election, Joshua McGinn, at (781) 575-2404.
