We cannot assure you of the exact amount or timing of any distribution to our stockholders under the Plan of Dissolution.
The liquidation and dissolution process is subject to numerous uncertainties, may fail to create value to our stockholders and may not result in any remaining capital for distribution to our stockholders. The precise nature, amount and timing of any distribution to our stockholders will depend on and could be delayed by, among other things, sales of our non-cash assets, claim settlements with creditors, resolution of the outstanding lawsuit, and unexpected or greater than expected expenses. Furthermore, any amounts to be distributed to our stockholders may be less than the price or prices at which our common stock has recently traded or may trade in the future.
