to amend the Schedule 13D, as amended (the "Schedule 13D") which
was originally filed on August 26, 1988. This Amendment No. 28 is

Item 5 to Schedule 13D is amended, in pertinent part, as
follows:
(a) The aggregate number and percentage of Securities to
which this Schedule 13D relates is 3,128,568 shares, representing
18.42% of the 16,985,613 shares outstanding as reported in the
Issuer's most recently filed Form 10-Q for the quarter ended
September 30, 1996. The Reporting Persons beneficially own those

(b) Each of the Reporting Persons and Covered Persons has
the sole power to vote or direct the vote and sole power to dispose
or to direct the disposition of the Securities reported for it,
either for its own benefit or for the benefit of its investment
clients or its partners, as the case may be, except that GAMCO
Investors, Inc. does not have authority to vote 102,233 of the
reported shares, and except that GFI has sole dispositive and
voting power with respect to the 742,200 shares of the Issuer held
by the the Funds, so long as the aggregate voting interest of all
joint filers does not exceed 25% of their total voting interest in
the Issuer and in that event, the Proxy Voting Committee of each of
the Funds shall respectively vote that Fund's shares, and except
that, at any time, the Proxy Voting Committee of each such Fund may
take and exercise in its sole discretion the entire voting power
with respect to the shares held by such Fund under special
circumstances such as regulatory considerations, and except that
the power of Mr. Gabelli and GFI is indirect with respect to
Securities beneficially owned directly by other Reporting Persons.
