This presentation and the accompanying oral commentary contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. All statements other than statements of historical fact could be deemed forward-looking, including, but not limited to, any statements about or relating to expectations, projections, trends, plans, ambitions, strategies, and objectives of management for the future; potential markets or market size, technology or business developments, including the anticipated launch of new products, capabilities and technologies, and the adoption or expansion of RAIN technologies by end users; enforceability of our intellectual property rights or our position within the industry; the impact of silicon wafer and reader component availability and supply; and any statements of assumptions underlying any of the foregoing.

Forward-looking statements are based on estimates and information available to us at the time of this presentation and are not guarantees of future performance. These forward-looking statements speak only as of the date hereof. Except as required by law, we assume no obligation and do not intend to update forward-looking statements or to conform these statements to actual results or to changes in our expectations. This presentation also contains statistical data, estimates and forecasts that are based on

independent industry publications or reports or other publicly available information, as well as other information based on our internal sources.

Actual results could differ materially from those expressed in forward-looking statements or in data or estimates made by independent parties or by us. Forward-looking statements, and any statistical data, estimates and forecasts contained in this presentation, are subject to significant risks, uncertainties and assumptions including those identified in the "Risk Factors" section and elsewhere in our most recent filings on Forms 10-K and 10-Q with the Securities and Exchange Commission (SEC).

In addition to our results determined in accordance with generally accepted accounting principles ("GAAP"), this presentation includes certain non-GAAP financial measures. Among other non-GAAP financial measures, this presentation uses (1) Adjusted EBITDA, which we calculate as GAAP net income (loss), excluding if applicable for the periods presented, the effects of stock-based compensation; depreciation; restructuring costs; settlement and related costs; induced conversion expense; other income, net; interest expense; loss on debt extinguishment; income tax benefit (expense); and acquisition transaction expense and related purchase accounting adjustments; (2) non-GAAP gross margin,

which we calculate as GAAP gross margin, excluding if applicable for the periods presented, the effects of depreciation, and the effects of stock-based compensation; and (3) Non-GAAP Net Income, which we calculate as net income (loss), adjusted for, if applicable for the periods presented, the effects of stock-based compensation; depreciation; restructuring costs; settlement and related costs; induced conversion expense; amortization of debt discount related to the equity component of our convertible notes; prepayment penalty on debt extinguishment; acquisition transaction expense and related purchase accounting adjustments; and the corresponding income tax impacts of adjustments to net income (loss). These non-GAAP financial measures are in addition to, and not as a substitute for or superior to measures of financial performance prepared in accordance with GAAP. There are a number of limitations related to the use of these non-GAAP financial measures versus their nearest GAAP equivalents, and our non-GAAP measures may be different from similarly termed non-GAAP measures used by other companies. See the appendix for a reconciliation of those measures to the most directly comparable GAAP measures.
