EXHIBIT 99.1

                         PRO FORMA FINANCIAL INFORMATION

The design and assets that are the subject of the disposition being reported by
this Form 8-K were acquired by the Company in connection with the acquisition of
certain assets from Tecmar Technologies International, Inc., and certain of its
affiliates, effective February 23, 2000 (the "Tecmar Acquisition"). The pro
forma statements of operations have been presented to give effect to the sale
transaction as if it had occurred at the beginning of the periods presented.
However, because the Company did not own the assets related to the disposition
until February 23, 2000, the following Unaudited Pro Forma Condensed
Consolidated Statement of Operations for the fiscal year ended June 30, 2000
present the results for the Company as if that acquisition had not occurred. The
Unaudited Pro Forma Condensed Consolidated Balance Sheet as of March 31, 2001
gives effect to the disposition as if it had occurred on March 31, 2001.

This Pro Forma Financial Information is presented for illustrative purposes
only. It is not necessarily indicative of the results of the remaining
operations or financial position which actually would have been reported had
the disposition occurred as the beginning of the periods presented, nor is it
necessarily indicative of the Company's future financial results of
operations.
