                             RULE 12b-25(b) and (c)

     If the subject report could not be filed without unreasonable effort or

     following should be completed. (Check box if appropriate)

[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 or semi-annual report, transition report on
     Form 10-K, 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 the

                                    PART III
                                    NARRATIVE

     State below in reasonable detail the reasons why the 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.

     The Company has recently completed an offering of its convertible senior
secured debentures in the principal amount of approximately $12.3 million (the
"Offering"). The completion of the Offering was announced by press release dated
February 10, 2004. The Company has also recently executed an asset purchase
agreement, which, subject to certain conditions, including the receipt of
approval of the Company's shareholders, provides for the Company's sale of
substantially all of its assets located at its Congers, New York facilities (the
"Asset Sale"). The execution of the asset purchase agreement was announced by
press release dated March 24, 2004. Due to the time-consuming nature of the
Offering and the Asset Sale, the completion of the Company's financial
statements for year ended December 31, 2003 and the Form 10-K has been delayed.
Management anticipates that filing of the Company's annual report on Form 10-K
for the fiscal year ended December 31, 2003 will occur on or before the 15th
calendar day following its prescribed due date.



                                     PART IV

(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                  [X] Yes No [ ]

     answer is no, please identify
     report(s).


(3)  Is it anticipated that any
     significant change in results of
     operations from the corresponding
     period for the last fiscal year                    [ ] Yes  No [X]
     will be reflected by the earnings

     subject report or portion thereof?

     If so: attach an explanation of the anticipated change, both narratively
     and quantitatively, and, if appropriate, state the reasons why a reasonable
