     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 appropriate box.)

[X]     (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, 20-F, 11-K or Form N-SAR, or portion thereof will be filed on
        or before the 15th calendar day following  the  prescribed  due date; or

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


                               Part III. Narrative

State below in reasonable  detail the reasons why Form 10-K,  11-K,  20-F, 10-Q,
N-SAR or the  transition  report  portion  thereof could not be filed within the
prescribed time period.

Registrant  and its  auditors  are in the  process  of  determining  the  proper
accounting treatment of the issuance of inducement shares in connection with the
conversion  of  convertible  preferred  stock as a condition to a recent  equity
transaction. The resolution of this issue may impact the calculation of net loss
available to common stock. As a result,  Registrant's  independent auditors have
been unable to complete their audit of the Registrant's financial statements for
the fiscal year ended December 31, 2001.

                      Part IV.  Other Information

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

          Jack Jaiven            561               640-3105
             (Name)          (Area Code)      (Telephone Number)


        (2) Have all other periodic  reports  required 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 12 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.

Registrant  expects to report in its Form 10-K a net loss of $14 million for the
year ended  December 31, 2001 as compared to a net loss of $21.9 million for the
year ended December 31, 2000. Included in the 2001 operating results is a fourth
quarter  write-down  of $2.5  million  resulting  from a  valuation  of  certain
inventory. Included in the 2000 operating results was a $12 million write-off of
unamortized  goodwill  attributable  to a 1999  acquisition  and a $1.4  million
inventory write-down.
