 FORWARD-LOOKING STATEMENTS  This presentation contains forward-looking statements. These forward-looking statements include statements related to sales, improved profitability, margin expansion, operations improvement, cost reductions, participation in strategic transactions, our strategy to align into pure-play businesses and our expectations for full year 2017 and 2018 revenue, Adjusted EBITDA and capital expenditures. Our ability to achieve these forward-looking statements is based on certain assumptions, including our ability to execute on our business strategy, leveraging of multiple routes to market, expanded brand awareness for high-performance Internet infrastructure services and customer churn levels. These assumptions may prove inaccurate in the future. Because such forward-looking statements are not guarantees of future performance or results and involve risks and uncertainties, there are important factors that could cause INAP’s actual results to differ materially from those expressed or implied in the forward-looking statements, due to a variety of important factors. Such important factors include, without limitation: our ability to execute on our business strategy into a pure-play business and drive growth while reducing costs; our ability to maintain current customers and obtain new ones, whether in a cost-effective manner or at all; the robustness of the IT infrastructure services market; our ability to achieve or sustain profitability; our ability to expand margins and drive higher returns on investment; our ability to sell into new and existing data center space; the actual performance of our IT infrastructure services and improving operations; our ability to correctly forecast capital needs, demand planning and space utilization; our ability to respond successfully to technological change and the resulting competition; the geographic concentration of the company’s data centers in certain markets and any adverse developments in local economic conditions or the demand for data center space in these markets; ability to identify any suitable strategic transactions; INAP's ability to realize anticipated revenue, growth, synergies and cost savings from the acquisition of SingleHop; INAP's ability to successfully integrate SingleHop’s sales, operations, technology, and products generally; the availability of services from Internet network service providers or network service providers providing network access loops and local loops on favorable terms, or at all; failure of third party suppliers to deliver their products and services on favorable terms, or at all; failures in our network operations centers, data centers, network access points or computer systems; our ability to provide or improve Internet infrastructure services to our customers; our ability to protect our intellectual property; our substantial amount of indebtedness, our possibility to raise additional capital when needed, on attractive terms, or at all, our ability to service existing debt or maintain compliance with financial and other covenants contained in our credit agreement; our compliance with and changes in complex laws and regulations in the U.S. and internationally; our ability to attract and retain qualified management and other personnel; and volatility in the trading price of INAP common stock.These risks and other important factors discussed under the caption “Risk Factors” in our most recent Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”), and our other reports filed with the SEC could cause actual results to differ materially from those indicated by the forward-looking statements made in this presentation. Given these risks and uncertainties, investors should not place undue reliance on forward-looking statements as a prediction of actual results. All forward-looking statements attributable to INAP or persons acting on its behalf are expressly qualified in their entirety by the foregoing forward-looking statements. All such statements speak only as of the date made, and INAP undertakes no obligation to update or revise publicly any forward-looking statements, whether as a result of new information, future events or otherwise.   © 2017 Internap Corporation (INAP) 

 NON-GAAP MEASURES  In addition to results presented in accordance with GAAP, this presentation includes non-GAAP financial measures. INAP believes these non-GAAP financial measures provide additional information that is useful to investors in helping to understand our underlying performance and trends. Non-GAAP financial measures have inherent limitations, which are not required to be uniformly applied. Readers should be aware of these limitations and should be cautious with respect to the use of such measures. To compensate for these limitations, we use non-GAAP financial measures as comparative tools, together with GAAP financial measures, to assist in the evaluation of our operating performance or financial condition. Our method of calculating these non-GAAP financial measures may differ from methods used by other companies. These non-GAAP financial measures should not be considered in isolation or as a substitute for those financial measures prepared in accordance with GAAP.As required by SEC rules, we have provided in this presentation reconciliations of the non-GAAP financial measures included in this presentation to the most directly comparable GAAP financial measures. Reconciliations of non-GAAP financial measures are also available in the attachment to our fourth quarter 2017 earnings press release available on our website at www.ir.inap.com.  © 2017 Internap Corporation (INAP)
