Forward-Looking Statements and Non-GAAP Financial Measures

This presentation contains forward-looking statements, including statements regarding our strategy, our ability to execute our brand promise, our long-term financial priorities, value creation for our stakeholders, and our target model

objectives. These forward-looking statements are based on our current assumptions and beliefs and involve risks and uncertainties that could cause our results to differ

materially from our forward-looking statements. Those risks and uncertainties include: a decline in client renewals, the loss of one or more of our key clients, the

contraction in our revenue from one or more of our key clients - either in the ordinary course of business or as a result of macroeconomic conditions resulting from the

COVID-19 pandemic - in each case resulting in churn, or our clients not expanding their relationships with us; economic or other adverse events or conditions affecting the technology industry, including as a result of the COVID-19 pandemic; and other risks and uncertainties described more fully in our periodic reports filed with the Securities and Exchange Commission, which can be obtained online at the Commission's website at http://www.sec.gov. All forward-looking statements in this press release are based on information currently available to us, and except as may

be legally required we assume no obligation to update these forward-looking statements.

This presentation also includes measures defined by the SEC as non-GAAP financial measures. ServiceSource believes these non-GAAP financial measures can provide

useful supplemental information to investors relating to its financial condition and results of operations when read in conjunction with the Company's reported results. These non-GAAP measures should not be considered a substitute for, or superior to, financial measures calculated in accordance with GAAP. Definitions of these non- GAAP financial measures and reconciliations to the closest GAAP financial measures are available in our earnings press releases posted on the Investor Relations portion of the ServiceSource website and at the end of the presentation.
