1 ARR includes Literacy and Enterprise and Education. 2 See definitions of non-GAAP financial metrics in appendix 147 To learn more please visit: RosettaStone.com Appendix Definitions of Statistical Measures

§ Annualized recurring revenue (or “ARR”) is computed using the annualized value of active subscription arrangements at the end of the period. ARR is a performance metric used to assess the health and trajectory of our E&E Language and Literacy segments, which we believe aids investors in understanding our segment results. We present ARR as a statistical measure rather than a non-GAAP financial measure. ARR should be viewed independently of revenue and deferred revenue, as ARR is a performance metric and is not intended to be combined with either of these items.

15 0 Definitions of Non-GAAP Financial Measures

§ Bookings represent executed sales contracts received by the Company that are either recorded immediately as revenue or as deferred revenue. § Adjusted EBITDA is GAAP net income /(loss) plus interest income and expense, other income /expense, income tax benefit and expense, impairment, depreciation, amortization, stock-based compensation, and restructuring expenses. In addition, Adjusted EBITDA excludes “Other” items related to the litigation with Google Inc., consulting and other related costs associated with the development and implementation of the accelerated strategy and cost reductions, non-restructuring wind down and severance costs, and transaction and other costs associated with mergers and acquisitions, as well as all adjustments related to recording the non-cash tax valuation allowance for deferred tax assets. Adjusted EBITDA for prior periods has been revised to conform to current definition. § Free cash flow is cash flow from operating activities minus cash used in purchases of property and equipment.

15 1 Definitions of Non-GAAP Financial Measures

§ Segment contribution is calculated as segment revenue less expenses directly incurred by or allocated to the segment. Direct segment expenses include costs and expenses that are directly incurred by or allocated to the segment and include materials costs, service costs, customer care and coaching costs, sales and marketing expenses, and bad debt expense. In addition to the previously referenced expenses, the Literacy segment includes direct research and development expenses and Combined Language includes shared research and development expenses, costs of revenue, sales and marketing, and general and administrative expenses applicable to the Consumer Language and Enterprise & Education Language segments.
