            The following constitutes Amendment No. 4 ("Amendment No. 4") to the
Schedule 13D filed by the undersigned.  This Amendment No. 4 amends the Schedule
13D as specifically set forth.

            Items 2 and 4 are hereby amended to add the following:

            At the Special Meeting of Shareholders of the Issuer held on October
11, 2005, the shareholders  approved the Committee's proposals (1) to remove all
the existing directors serving on the Issuer's Board of Directors without cause,
(2) to fix the number of members of the Issuer's Board of Directors at five, and
(3) to elect the Committee's slate of director nominees, Eric Rosenfeld, Karl L.
Meyer, Robert F. Walters, Frank J. Tanki and Willem van Rijn, based on certified
voting  results  that  were  announced  by  the  Issuer  on  October  18,  2005.
Accordingly,  the Section 13D group comprised of the Reporting  Persons has been
disbanded effective October 19, 2005 and FAS Trust, RLS Trust, Family Trust, RLS
Investments,  Richard L.  Scott,  Stephen T.  Braun,  Karl L.  Meyer,  Robert F.
Walters,  Frank J. Tanki and Willem  van Rijn are no longer  Reporting  Persons.
There are currently no agreements between or among FAS Trust, RLS Trust,  Family
Trust,  RLS  Investments,  Richard L. Scott,  Stephen T.  Braun,  Karl L. Meyer,
Robert F.  Walters,  Frank J. Tanki and Willem van Rijn nor  between any of them
and Crescendo Partners II, Crescendo  Investments II or Eric Rosenfeld regarding
the  securities  of the  Issuer.  As  disclosed  in the proxy  statement  of the
Committee with respect to the  solicitation  of proxies at the Special  Meeting,
Crescendo  Partners II and RLS Investments  intend to seek  reimbursement of the
costs of the  solicitation  from the Issuer.  Crescendo  Partners II,  Crescendo
Investments II and Eric Rosenfeld will continue filing as a group  statements on
Schedule 13D with respect to their  beneficial  ownership of  securities  of the
Issuer to the extent required by law.

            Item 5(a) is hereby amended and restated as follows:

            The  aggregate  percentage of Shares  reported  owned by each person
named herein is based upon  31,427,849  Shares  outstanding,  which is the total
number of Shares  reported to be  outstanding in the Issuer's  definitive  proxy
statement on Schedule 14A, as filed with the Securities and Exchange  Commission
on September 14, 2005.

            As of the close of business on October 20, 2005,  Crescendo Partners
II beneficially owned 2,401,600 Shares,  constituting  approximately 7.6% of the
Shares  outstanding.  As the general partner of Crescendo Partners II, Crescendo
Investments II may be deemed to beneficially  own the 2,401,600  Shares owned by
Crescendo   Partners  II,   constituting   approximately   7.6%  of  the  Shares
outstanding.  As the managing member of Crescendo  Investments II, which in turn
is the general partner of Crescendo  Partners II, Mr. Rosenfeld may be deemed to
beneficially  own the  2,401,600  Shares owned by Crescendo  Partners II, which,
together with the 10,000 Shares underlying an option awarded to Mr. Rosenfeld as
discussed below, constitutes  approximately 7.7% of the Shares outstanding.  Mr.
Rosenfeld  has sole voting and  dispositive  power with respect to the 2,401,600
Shares  owned by  Crescendo  Partners II by virtue of his  authority to vote and
dispose of such Shares.  Crescendo  Investments  II and Mr.  Rosenfeld  disclaim
beneficial  ownership of the Shares held by Crescendo Partners II, except to the
extent of their pecuniary interest therein.

Mr.  Scott has sole  voting and  dispositive  power with  respect to the 333,996
Shares  owned  by FAS  Trust,  constituting  approximately  1.1%  of the  Shares
outstanding. Mr. Braun has sole voting and dispositive power with respect to the
aggregate of 491,004  Shares owned by RLS Trust and Family  Trust,  constituting

the  Issuer,  effective  October 18,  2005,  each of Messrs.  Rosenfeld,  Meyer,
Walters,  Tanki and van Rijn was awarded an  immediately  exercisable  option to
purchase  10,000 Shares pursuant to the Issuer's 1991  Non-Qualified  Directors'
Stock  Option  Plan.  Messrs.  Meyer,  Walters,  Tanki  and  van  Rijn  and  RLS
Investments do not otherwise own any securities of the Issuer.

            Item 5(c) is hereby amended to add the following:

            There have been no  transactions  in the securities of the Issuer by
the  Reporting  Persons  since the filing of Amendment No. 3 to the Schedule 13D
other than the option awards discussed in Item 5(a).

Walters,  Frank J. Tanki and Willem van Rijn ceased to be the beneficial  owners
of more than 5% of the Shares of the Issuer.

            Item 6 is hereby amended to add the following:

            Effective October 19, 2005, the Reporting  Persons  terminated their
obligations under the Joint Filing and Solicitation Agreement.

            Item 7 is hereby amended to add the following exhibit:

            8.   Joint  Filing  Agreement  by and among  Crescendo  Partners II,
