Forward-Looking Statements This release contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934 and the Private Securities Litigation Reform Act of 1995. These forward-looking statements include statements regarding our strategy, prospects,customer demand, application adoption and our financial outlook for the second quarter of, and full year, 2018. Forward-looking statements are subject to known and unknown risks and uncertainties and are based on potentially inaccurate assumptions that could cause actual results to differ materially from those expected or implied by the forward-looking statements. Actual results may differ materially from the results predicted, and reported results should not be considered as an indication of future performance. The potential risks and uncertainties that could cause actual results to differ from the results predicted include, among others, those risks and uncertainties included under the caption "Risk Factors" and elsewhere in our filings with the U.S. Securities and Exchange Commission, including, without limitation, the Form 10-K filed with the SEC on February 21, 2018.  All information provided in this release and in the attachments is as of the date hereof, and we undertake no duty to update this information unless required by law.

Non-GAAP Financial Measures To supplement our condensed consolidated financial statements, which are prepared and presented in accordance with Generally Accepted Accounting Principles in the United States of America (GAAP), we use the following non-GAAP financial measures: non-GAAP gross margin, non-GAAP operating loss, non-GAAP net loss per basic and diluted share, and free cash flow. In computing these measures, with the exception of free cash

flow, we exclude the effects of stock-based compensation expense, acquisition-related expenses, and amortization of acquisition-related intangible assets. We define free cash flow as net cash used in operating activities, less the purchases of property and equipment. The presentation of this non-GAAP financial information is not intended to be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP, and our non-GAAP measures may be different from non-GAAP measures used by other companies.

We use these non-GAAP financial measures for financial and operational decision-making and as a means to evaluate period-to-period comparisons. Our management believes that these non-GAAP financial measures provide meaningful supplemental information regarding our performance and liquidity by excluding certain expenses and expenditures that may not be indicative of our ongoing core business operating results. We believe that both management and investors benefit from referring to these non-GAAP financial measures in assessing our performance and when analyzing historical performance and liquidity and planning, forecasting, and analyzing future periods.

For a reconciliation of these non-GAAP financial measures to GAAP measures, please see the tables captioned "Results of Operations GAAP to Non-GAAP Reconciliation" included at the end of this release. We have not reconciled guidance for non-GAAP metrics to their most directly comparable GAAP measures because such items that impact these measures are not within our control or cannot be reasonably predicted.
