EXPLANATORY NOTE

A total of 6,000,000 shares of common stock of UST Inc. (the "Company" or
"Registrant") were registered in connection with the Company's Amended and
Restated Stock Incentive Plan (the "2001 Plan") by a registration statement on
Form S-8, File No. 333-60698, filed on May 11, 2001 (as amended by
Post-Effective Amendment No. 2, filed on May 9, 2003, the "2001 Form S-8"). On
May 3, 2005, the stockholders of the Company approved the Company's 2005 Long
Term Incentive Plan (the "2005 Plan"), reserving 10,000,000 shares for
options, restricted stock, and a variety of other types of awards. As of the
date hereof, of the 6,000,000 shares registered in connection with the 2001
Plan, 3,502,470 shares (i) have not been issued and are not subject to
issuance upon the exercise of outstanding awards granted or (ii) were subject
to outstanding awards that subsequently ceased to be subject to such awards
(as a result of cancellations, termination, forfeitures or expirations of
options).

This Post-Effective Amendment No. 2 to the 2001 Form S-8 is filed to provide
that up to 3,502,470 shares available for issuance under the 2001 Plan will no
longer be available for offer and sale under the 2001 Plan, but will be
available for offer and sale under the 2005 Plan. On or about the date hereof,
the Company is filing a registration statement (the "2005 Form S-8") which is
carrying forward the 3,502,470 shares under the 2001 Plan and 5 shares of
common stock registered in connection with the UST Inc. Nonemployee Directors'
Stock Option Plan (the "1995 Plan") by a registration statement on Form S-8,
File No. 033-59229, filed on May 11, 1995 (the "1995 Form S-8").

Pursuant to Instruction E to Form S-8 and the telephonic interpretation of the
Securities and Exchange Commission set forth at pages 123-124 of the Division
of Corporation Finance's Manual of Publicly Available Telephone
Interpretations, dated July 1997 (see G. Securities Act Forms, number 89)
3,502,470 shares of common stock registered on the 2001 Form S-8 are carried
forward to, and deemed covered by, the 2005 Form S-8. In addition, 5 shares of
common stock registered on the 1995 Form S-8 are carried forward to, and
deemed covered by, the 2005 Form S-8, by a Post-Effective Amendment No. 1 to
the 1995 Form S-8 filed on or about the date hereof. No additional
registration fee is due with respect to the shares covered being carried
forward as all were covered by prior Forms S-8.

In addition, any shares that are not issued pursuant to outstanding options
granted under the 2001 Plan, such as when a currently outstanding option
expires, is cancelled, terminated or is forfeited, will be carried forward for
issuance in connection with the 2005 Plan and deemed covered by this
Post-Effective Amendment No. 2 to the 2001 Form S-8.

Shares remain subject to outstanding options previously granted under the 2001
Plan and the 1995 Plan and consequently the 2001 Form S-8 and the 1995 Form
S-8 will remain in effect to cover the potential exercise of such outstanding
options.
