PART II -- RULES 12b-25(b) AND (c)

If the subject report could not be filed without unreasonable effort or expense
and the registrant seeks relief pursuant to Rule 12b-25(b), the following should
be completed. (Check box if appropriate)

         (a) The reasons described in reasonable detail in Part III of this form
             could not be eliminated without unreasonable effort or expense;

[X]      (b) The subject annual report, semi-annual report, transition report on
             Form 10-K, Form 10KSB, 20-F, 11-K or Form N-SAR, or portion
             thereof, will be filed on or before the fifteenth calendar day
             following the prescribed due date; or the subject quarterly report
             or transition report on Form 10-Q, 10QSB or portion thereof, will
             be filed on or before the fifth calendar day following the
             prescribed due date; and

         (c) The accountant's statement or other exhibit required by Rule
             12b-25(c) has been attached if applicable.

PART III -- NARRATIVE

         The registrant will not file its Form 10-K by March 16, 2005, because
it will be unable to complete the preparation of its consolidated financial
statements by the initial filing date without unreasonable effort or expense
due, in part, to the additional work that was required to complete management's
assessment of internal controls over financial reporting in accordance with
Section 404 of Sarbanes-Oxley. The registrant continues to dedicate significant
resources to the audit of the financial statements. The registrant currently
anticipates that it will be able to file its complete Annual Report on Form 10-K
by March 31, 2005.

PART IV -- OTHER INFORMATION

(1)      Name and telephone number of person to contact in regard to this
         notification:

           Richard T. Kelecy              352                 395-1351
         ---------------------      --------------      --------------------
                (Name)                (Area Code)         (Telephone Number)

(2)      Have all other periodic reports under Section 13 or 15(d) of the
         Securities Exchange Act of 1934 or Section 30 of the Investment Company
         Act of 1940 during the preceding twelve months or for such shorter
         period that the registrant was required to file such report(s) been
         filed? If the answer is no, identify report(s).          [X] YES [ ] NO

(3)      Is it anticipated that any significant change in results of operations
         from the corresponding period for the last fiscal year will be
         reflected by the earnings statements to be included in the subject
         report, or portion thereof?                              [X] YES [ ] NO

         If so, attach an explanation of the anticipated change, both
         narratively and quantitatively, and, if appropriate, state the reasons
         why a reasonable estimate of the results cannot be made.

         The registrant estimates that it will have a net loss for fiscal year
2004 of approximately $19 million, as compared to net income of $2.9 million for
fiscal year 2003, due in large part to discontinued operations, and write-downs
as a result of impairment of fixed and intangible assets, as more fully
described in the registrant's Form 10-Q for the quarter ended September 30,
2004.
