Investools Cautionary Statements

3 The Securities and Exchange Commission’s Regulation G applies to any public disclosure or release of material information that includes a non-GAAP financial measure. In the event of such a disclosure or release, Regulation G requires: (i) the presentation of the most directly comparable financial measure calculated and presented in accordance with GAAP and (ii) a reconciliation of the differences between the non-GAAP financial measure presented and the most directly comparable financial measure calculated and presented in accordance with GAAP. The required presentations and reconciliations are contained herein and can be found at our website, www.investools.com, under “Investor Relations”, “Webcasts and Presentations”. Investools Education Group uses the non-GAAP financial measure “sales transaction volume” or “STV,” which is defined as revenue plus deferred revenue, to assess the operating results and effectiveness of the Company and its business segments. STV is consistent with the selling activities in the period reported and with the level of a majority of the cost components of cost of revenue. Given the impact of accounting for deferred revenue and for costs associated with deferred revenue, the Company also uses the non-GAAP financial measure “Adjusted EBITDA” as a valuable representation of the Company’s operating performance. Adjusted EBITDA is defined as net income (loss) plus depreciation and amortization, interest income, special charges, other non-cash items, and the net change in deferred revenue. The Company believes that the non-GAAP financial measures described above are also useful to investors, financial analysts and others to evaluate the operating and financial performance of the Company. These non-GAAP financial measures may not be comparable to similarly titled measurements used by other companies and should not be used generally as a substitute for revenue, net income (loss) or other GAAP operating measurements. The acquisition by Investools Inc. of thinkorswim Group, Inc. and its subsidiaries occurred on February 15, 2007. The pro forma information has been prepared by combining the relevant consolidated financial information of each of Investools Inc. and thinkorswim Group, Inc. for the time periods presented. The unaudited pro forma consolidated financial information is provided for informational purposes only. In addition, the unaudited pro forma consolidated financial information does not purport to project our future financial position, operating results or sales. No effect has been given in the unaudited pro forma consolidated statement of income for synergistic benefits that may be realized through the combination of the two companies or the costs that may be incurred in integrating the companies acquired in such acquisition. In addition, no adjustments have been made to give pro forma effect as if the merger had occurred at the beginning of the period presented, which adjustments are typically found in pro forma financial statements. The unaudited pro forma consolidated financial information should be read in conjunction with our historical financial statements and related notes and the historical financial statements of thinkorswim, which are included in our current report on Form 8-K filed with the Securities and Exchange Commission on February 22, 2007, Form 10-K filed with the Securities and Exchange Commission on March 17, 2008, and Form 10-Qs filed with the Securities and Exchange Commission on May 10, 2007, November 14, 2007 and November 21, 2007.
