Amendment No. 1 to Schedule 13D
The information reported previously in Unitrin's Schedule 13D, dated August
10, 1998 (the "August 1998 13D") is supplemented with the following information.
Capitalized terms used below and not otherwise defined have the meanings given
to such terms in the August 1998 13D.
Item 5. Interest in Securities of the Issue
On October 19, 1998, Unitrin acquired 14,717,667 shares of the Issuer's
Common Stock (the "Transferred Shares") from its wholly-owned subsidiary, United
Insurance Company of America, in an intercompany transaction. The Transferred
Shares were part of the shares as to which Unitrin reported shared voting and
dispositive powers in the August 1998 13D. As a result of the transfer, Unitrin
now has sole voting and dispositive powers with respect to the Transferred
Shares. Except for this intercompany transfer, Unitrin has not acquired or
disposed of any shares of the Issuer's Common Stock since the August 1998 13D.
This Amendment No. 1 reports one fewer share of the Issuer's Common Stock than
the August 1998 13D due to the surrender of a fractional share for cash. Another
of Unitrin's wholly-owned subsidiaries, Trinity Universal Insurance Company,
continues to hold 19,458,295 shares of the Issuer's Common Stock and shares
voting and dispositive powers with Unitrin, as reported in the August 1998 13D.
Accordingly, Unitrin's total beneficial ownership, direct and indirect, of the
Issuer's Common Stock remains constant at 34,175,962 shares.
Signature
After reasonable inquiry and to the best of my knowledge and belief, I
certify that the information set forth in this statement is true, complete and
correct.
