from their 10k:

We have cash requirements for ongoing operating expenses, capital expenditures, working capital, and general corporate purposes, which we may be unable to obtain.

Accordingly, our stockholders may not be able to realize a fair price from their shares when they determine to sell them or may have to hold them for a substantial period of time until the market for our common stock improves.
