      (2) Have all other periodic reports required under Section 13 or 15(d) of

      (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.

      In December, 2001 the Company determined that $5,802,000 of goodwill
associated with its OSS business unit was impaired and as such recorded an
impairment loss. This assessment was based on the continued decline in sales and
losses generated by the business unit over the past several years and the
prospects for additional sales of the products based on the older technology
that originally gave rise to the goodwill.
