|The Company's financial statements have been presented on the basis that it is a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The Company's significant operating losses and its working capital deficit and stockholders' deficit raise substantial doubt about its ability to continue as a going concern. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

|In January 1997, the Company entered into a manufacturing and marketing license agreement with Lawrence Livermore National Laboratories ("Lawrence Livermore") whereby the Company obtained the rights to Lawrence Livermore's patented Capacitive Deionization Technology ("CDT"). The Company has the rights to develop and manufacture a carbon aerogel CDT product for commercial use in the desalination, filtration and purification of water. The manufacturing and marketing license is effective for the life of the patents (up to 17 years). To maintain the license the Company must make contracted annual royalty payments to Lawrence Livermore beginning at $25,000 per year, then becoming a percentage of revenue.

|The Company applies the provisions of Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees" and related interpretations, in accounting for its stock-based compensation plans. Under Opinion 25, compensation cost is measured as the excess, if any, of the market price of the Company's stock at the date of the grant above the amount an employee must pay to acquire the stock. No compensation expense is recognized when the exercise price is equal to the market value of the stock on the day of the grant. The Financial Standards Board ("FASB") published SFAS No. 123, "Accounting for Stock-Based Compensation" (SFAS No. 123) on January 1, 1996 which encourages, but does not require, companies to recognize compensation expense for grants of stock, stock options and other equity instruments to employees based on new fair value accounting rules. Companies that choose not to adopt the new rules will continue to apply the existing rules, but will be required to disclose pro forma net income under the new method.
