          On November 22, 1998, UNUM Corporation (the "Company") executed
an amendment (the "Amendment") to the Rights Agreement, dated as of March
13, 1992, as amended (the "Rights Agreement"), between the Company and
First Chicago Trust Company of New York, as Rights Agent. The Amendment
provides that neither Provident Companies, Inc., a Delaware corporation
("Provident"), nor any of its respective Affiliates or Associates will
become an Acquiring Person (as that term is defined in the Rights
Agreement) as a result of the occurrence of any of the following: (i) the
execution of the Agreement and Plan of Merger dated as of November 22,
1998, between the Company and Provident, (the "Merger Agreement"), the
execution of the Stockholders Agreement (as defined in the Merger
Agreement) or the Option Agreements (as defined in the Merger Agreement),
(ii) the announcement of the Merger (as defined in the Merger Agreement),
(iii) the acquisition of Common Stock of the Company pursuant to the
Merger, the Merger Agreement or the Option Agreements or (iv) the
consummation of the Merger or of the other transactions contemplated by the
Merger Agreement, the Stockholders Agreement or the Option Agreements. The
Amendment further provides that, despite the occurrence of any of the
events described under (i), (ii), (iii) or (iv) above, a Distribution Date,
Triggering Event or Stock Acquisition Date (as such terms are defined in
the Rights Agreement) will not occur, no Rights will separate from the
shares of Common Stock or otherwise become exercisable and no adjustment
will be made pursuant to Sections 11 or 13 of the Rights Agreement.

          The foregoing description of the Amendment is qualified in its
entirety by reference to the full text of the Amendment attached hereto as
Exhibit A and incorporated herein by reference, to the Amendment No. 1 to
the Rights Agreement attached as an exhibit to the Form 8-A/A filed on June
