UNAUDITED PRO FORMA COMBINED CONSOLIDATED FINANCIAL INFORMATION

The accompanying unaudited pro forma combined consolidated financial statements present financial information from the ISCO and Clarity unaudited pro forma combined consolidated statement of operations for the nine months ended September 30, 2007 and for the year ended December 31, 2006 and the unaudited pro forma combined consolidated balance sheet as of September 30, 2007 is based on the historical balance sheets of ISCO and Clarity as of that date. The unaudited pro forma combined consolidated statement of operations is presented as if the Merger had occurred on the first day of the period (i.e., October 1, 2007). The unaudited pro forma combined consolidated balance sheet gives effect to the transaction as if it occurred on September 30, 2007. The unaudited pro forma combined consolidated financial data are based on estimates and assumptions, which are preliminary and subject to change, as set forth in the notes to such statements and which are provided for information purposes only. The unaudited pro forma combined consolidated financial data are not necessarily indicative of the financial position or operating results that would have been achieved had the Merger been consummated as of the dates indicated, nor are they necessarily indicative of future financial position or operating results. This information should be read in conjunction with the historical financial statements and related notes of ISCO included in ISCO's Annual Report on Form 10-K and Quarterly Reports on Form 10-Q and Clarity included this Current Report on Form 8-K.
