(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 reports been filed? If answer is no,
identify report(s).

    [ ] Yes     [X] No

The Registrant's Annual Report on Form 10-K for the fiscal year ended December
31, 2002 has not been filed.

(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.

Explanation:

The Registrant expects to report net sales for its 2003 first quarter of
approximately $4.8 million, as compared to $7.9 million for its 2002 first
quarter. This decline in net sales, along with, among other things,
deteriorating pricing conditions, negatively impacted financial performance
which was offset by cost reductions implemented by the Company. The Registrant
expects to report net income (loss) for its 2002 first quarter of approximately
($4 million) as compared to net income (loss) for its 2002 first quarter of
($4.1 million). The aforementioned anticipated financial results are subject to
change between the date hereof and the date the Registrant's quarterly report on
Form 10-Q is filed.
