 Item 1A. RISK FACTORS
  RISK FACTORS RELATING TO OUR BUSINESS AND THE INDUSTRY IN WHICH WE OPERATE
 We have experienced net losses in prior periods. Future losses are possible.
  We may need to raise additional capital in the future to fund our operations. We may be unable to
raise funds when needed or on acceptable terms.
  20

##### Table of Contents



A significant portion of our sales is to customers in foreign countries. We may lose revenues,
market share, and profits due to exchange rate fluctuations and other factors related to our
foreign business.
   We currently rely on two distributors for a significant percentage of our sales. If our
relationship with these distributors were to deteriorate, our sales may materially decline.
  Our financial results could be adversely impacted by recording impairment losses or incurring
capital losses on stock sales in connection with our ownership of HAPC common stock.
 Accounting for Certain
Investments in Debt and Equity Securities
 RISK FACTORS RELATED SPECIFICALLY TO OUR COMMON STOCK
 The average trading volume for our common stock is relatively low when compared to most larger
companies. As a result, there may be less liquidity and more volatility associated with our common
stock, even if our business is doing well.
