– SIGNIFICANT CUSTOMERS, CONCENTRATION OF CREDIT RISK, AND GEOGRAPHIC INFORMATION

We have no outstanding debt nor do we utilize auction rate securities or derivative financial instruments in our investment portfolio.

Cash and other investments

may

be in excess of FDIC insurance limits.

Our financial results could be affected by changes in foreign currency exchange rates or weak economic conditions in foreign markets. As all sales are currently made in U.S. dollars, a strengthening of the dollar could make our products less competitive in foreign markets.
