Q1 2010 Financial Results Conference Call Slides May 6, 2010

Safe harbor summary These slides and accompanying oral presentation contain forward-looking statements including our guidance for the second quarter of 2010 and the full year 2010, the expected release dates of Rosetta Stone Version 4 TOTALe and Rosetta Stone iPhone/iPod Touch, the costs of our launch of Rosetta Stone Version 4 TOTALe and our litigation with Google. These statements relate to future events or to future financial performance and involve known and unknown risks, uncertainties, and other factors that may cause our actual results, levels of activity, performance, or achievements to be materially different from any future results, levels of activity, performance, or achievements expressed or implied by these forward-looking statements. In some cases, you can identify forward-looking statements by the use of words such as “may,” “could,” “expect,” “intend,” “plan,” “seek,” “anticipate,” “believe,” “estimate,” “predict,” “potential,” or “continue” or the negative of these terms or other comparable terminology. You should not place undue reliance on forward-looking statements because they involve known and unknown risks, uncertainties and other factors that are, in some cases, beyond our control and that could materially affect actual results, levels of activity, performance, or achievements. Factors that could materially affect actual results, levels of activity, performance or achievements include those listed under the caption “Risk Factors” of Rosetta Stone’s Form 10-K dated March 10, 2010. If any of these risks or uncertainties materialize, or if our underlying assumptions prove to be incorrect, actual results may vary significantly from what we projected. Any forward-looking statement you see or hear during this presentation reflects our current views with respect to future events and is subject to these and other risks, uncertainties, and assumptions relating to our operations, results of operations, growth strategy, and liquidity. We assume no obligation to publicly update or revise these forward-looking statements for any reason, whether as a result of new information, future events, or otherwise.

Use of non-GAAP measures This presentation contains five non-GAAP financial measures: non-GAAP net income, non-GAAP net income per share, Adjusted EBITDA, Operating EBITDA and non-GAAP operating income. These measures differ from GAAP in that they exclude amortization primarily related to acquired intangibles, stock-based compensation expenses, IPO-related compensation expenses, and fees associated with the company’s canceled secondary stock offering in August 2009. Adjusted EBITDA is GAAP net income or loss plus interest expense, income tax expense, depreciation, amortization and stock-based compensation expenses. Operating EBITDA is Adjusted EBITDA plus the change in deferred revenue. An additional non-GAAP financial measure in this press release is total sales bookings, which represents executed sales contracts received by the company that are either recorded immediately as revenue or as deferred revenue.
