(“ConvergeOne” or the “Company”) by which ConvergeOne will become a subsidiary of Forum (the “Transaction”). No Offer or Solicitation This Presentation is for informational purposes only and is neither an offer to purchase, nor a solicitation of an offer to sell, subscribe for or buy any securities or the solicitation of any vote in any jurisdiction pursuant to the proposed Transaction or otherwise, nor shall there be any sale, issuance or transfer or securities in any jurisdiction in contravention of applicable law. No offer of securities shall be made except by means of a prospectus meeting the requirements of Section 10 of the Securities Act of 1933, as amended. Forward-Looking Statements This Presentation includes “forward‐looking statements” regarding ConvergeOne, its financial condition and its results of operations that reflect ConvergeOne’s current views and information currently available. This information is, where applicable, based on estimates, assumptions and analysis that ConvergeOne believes, as of the date hereof, provide a reasonable basis for the information contained herein. Forward‐looking statements can generally be identified by the use of forward‐looking words such as “may”, “will”, “would”, “could”, “expect”, “intend”, “plan”, “aim”, “estimate”, “target”, “anticipate”, “believe”, “continue”, “objectives”, “outlook”, “guidance” or other similar words, and include statements regarding ConvergeOne’s plans, strategies, objectives, targets and expected financial performance. These forward‐looking statements involve known and unknown risks, uncertainties and other factors, many of which are outside the control of Forum, ConvergeOne and their respective officers, employees, agents or associates. Actual results, performance or achievements may differ materially, and potentially adversely, from any projections and forward‐looking statements and the assumptions on which those vary from forward‐looking statements are based. There can be no assurance that the data contained herein is reflective of future performance to any degree. You are cautioned not to place undue reliance on forward‐looking statements as a predictor of future performance as projected financial information, cost savings, synergies and other information are based on estimates and assumptions that are inherently subject to various significant risks, uncertainties and other factors, many of which are beyond our control. All information herein speaks only as of (1) the date hereof, in the case of information about ConvergeOne, or (2) the date of such information, in the case of information from persons other than ConvergeOne. ConvergeOne undertakes no duty to update or revise the information contained herein. Forecasts and estimates regarding ConvergeOne’s industry and end markets are based on sources we believe to be reliable, however there can be no assurance these forecasts and estimates will prove accurate in whole or in part. Use of Projections This Presentation contains financial forecasts with respect to, among other things, ConvergeOne’s revenue, Adjusted EBITDA, Pro Forma Adjusted EBITDA, Free Cash Flow and certain ratios and other metrics derived therefrom for the fiscal years 2017 and 2018. These unaudited financial projections have been provided by ConvergeOne’s management, and ConvergeOne’s independent auditors have not audited, reviewed, compiled, or performed any procedures with respect to the unaudited financial projections for the purpose of their inclusion in this Presentation, and accordingly, do not express an opinion or provided any other form of assurance with respect thereto for the purpose of this Presentation. These unaudited financial projections should not be relied upon as being necessarily indicative of future results. The inclusion of the unaudited financial projections in this Presentation is not an admission or representation by ConvergeOne or Forum that such information is material. The assumptions and estimates underlying the unaudited financial projections are inherently uncertain and are subject to a wide variety of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the unaudited financial projections. There can be no assurance that the prospective results are indicative of the future performance of Forum or ConvergeOne or that actual results will not differ materially from those presented in the unaudited financial projections. Inclusion of the unaudited financial projections in this Presentation should not be regarded as a representation by any person that the results contained in the unaudited financial projections will be achieved. Industry and Market Data The information contained herein also includes information provided by third parties, such as market research firms. None of Forum, Forum Investors I, LLC, the sponsor of Forum, ConvergeOne, Clearlake Capital Group L.P. (“Clearlake”), and their respective affiliates and any third parties that provide information to Forum, such as market research firms, guarantee the accuracy, completeness, timeliness or availability of any information. None of Forum, ConvergeOne, Clearlake and their respective affiliates and any third parties that provide information to Forum, such as market research firms, are responsible for any errors or omissions (negligent or otherwise), regardless of the cause, or the results obtained from the use of such content. None of Forum, ConvergeOne, Clearlake and their respective affiliates give any express or implied warranties, including, but not limited to, any warranties of merchantability or fitness for a particular purpose or use, and they expressly disclaim any responsibility or liability for direct, indirect, incidental, exemplary, compensatory, punitive, special or consequential damages, costs expenses, legal fees or losses (including lost income or profits and opportunity costs) in connection with the use of the information herein. Non-GAAP Financial Measures This Presentation includes certain financial measures not presented in accordance with generally accepted accounting principles (“GAAP”) including, but not limited to, Adjusted EBITDA and Pro Forma Adjusted EBITDA and certain ratios and other metrics derived therefrom. These non‐GAAP financial measures are not measures of financial performance in accordance with GAAP and may exclude items that are significant in understanding and assessing ConvergeOne’s financial results. Therefore, these measures should not be considered in isolation or as an alternative to net income, cash flows from operations or other measures of profitability, liquidity or performance under GAAP. You should be aware that ConvergeOne’s presentation of these measures may not be comparable to similarly‐titled measures used by other companies. You can find the reconciliation of these measures to the nearest comparable GAAP measures elsewhere in this Presentation. ConvergeOne believes that these non-GAAP measures of financial results provide useful information to management and investors regarding certain financial and business trends relating to ConvergeOne’s financial condition and results of operations. ConvergeOne’s management uses these non-GAAP measures to compare ConvergeOne’s performance to that of prior periods for trend analyses, for purposes of determining management incentive compensation, and for budgeting and planning purposes. These measures are used in monthly financial reports prepared for management and ConvergeOne’s board of directors. ConvergeOne believes that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends. Management of ConvergeOne does not consider these non-GAAP measures in isolation or as an alternative to financial measures determined in accordance with GAAP.
