PART IV--OTHER INFORMATION

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

             Arnold P. Agbayani               (408)             982-0700
     ------------------------------------  ----------- -------------------------

(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 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.

Operating results for fiscal year 1999 is a net loss of $5.2 million as compared
to net income for fiscal year 1998 of $6.1 million. The primary reason for the
decrease in operating results was related to the acquisition of Paradigm
Technologies, Inc., and the related write-off of goodwill, in-process-research
and development and related amortization in the amount of $10.4 million.

Revenues for fiscal year 1999 were $66.5 million as compared to $56.9 million,
or a 17% increase.  The increase is primarily related to approximately a 39%
increase in units shipped offset by a 16% decrease in average selling prices
comparing 1999 to 1998.  Gross margin for 1999 was 32% as compared to 33% in
1998.

For fiscal year ended 1999, research and development was $4.2 million or 6.3% of
net revenues as compared to $3.3 million or 5.8% of net revenues for fiscal year
1998.  The increase in dollar terms is related to higher engineering headcount
in 1999.  For 1999, selling, general, administrative expenses (SG&A) was $20.3
million of 30.4% as compared to $8.4 million or 14.7% of net sales in fiscal
year end 1998.  The increase reflects the $10.4 million write-off of goodwill
and in-process research and development and related amortization.

Interest expense was $993,000 for fiscal year end 1999 as compared to $431,000
for fiscal year end 1998. The increase is related to higher average borrowings
for 1999. Other income was $669,000 as compared to $3.5 million in 1998, which
included $3.7 million attributable to the settlement of a patent claim.
Provision for income taxes is 66% in 1999 as compared to 41% in 1998. The
increase in effective rate reflects the deductible portion of the Paradigm
write-off.
