All rights reserved. 2 Forward Looking Statement Forward-looking statements in this Investor Presentation are subject to known and unknown risks, uncertainties and other factors which may cause our actual results, performance or achievements to be materially different from any future results, performance, or achievements expressed or implied by such forward-looking statements. These forward-looking statements were based on various factors and were derived utilizing numerous assumptions. Words such as “anticipates,” “estimates,” “expects,” “projects,” “intends,” “plans,” “believes” and words or terms of similar substance used in connection with any discussion of future operating results or financial performance identify forward-looking statements. These include, among others, statements relating to the timing and benefits of strategic initiatives. Factors that could cause actual results to differ materially from those contemplated by the forward-looking statements include, among others, the following factors: (i) the issuer's operating results may be lower than expected; (ii) the issuer's ability to implement its strategic initiatives and any consequences from its pursuit of its corporate strategy; (iii) competition, economic, political and market conditions and fluctuations, including interest rate risk; (iv) government and industry regulation; (v) adverse changes that may occur in the securities markets generally; or (vi) any loss by the issuer of significant trading volume or listed companies. Most of these factors are difficult to predict accurately and are generally beyond the issuer's control. You should consider the uncertainty and any risk resulting from such uncertainty in connection with any forward-looking statements that may be made herein. Readers are cautioned not to place undue reliance on these forward- looking statements, which speak only as of TODAY’S date. Readers should carefully review OUR PUBLIC FILINGS WITH THE SEC, INCLUDING OUR MOST RECENT FORM 10-K AND FORM 10-Q, including, but not limited to, the SECTIONS ENTITLED “RISK FACTORS,” “Management’s Discussion and Analysis of Financial Condition and Results of Operation,” financial statements and the accompanying notes. Except for our ongoing obligations to disclose material information under the federal securities laws, the issuer undertakes no obligation to release publicly any revisions to any forward-looking statements, to report events or to report the occurrence of unanticipated events. For any forward-looking statements contained in any document, the issuer claims the protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995. Non-GAAP Information In addition to disclosing results determined in accordance with U.S. generally accepted accounting principles (“GAAP”), NASDAQ OMX also discloses certain non- GAAP results of operations, including total expenses, operating income, net income and diluted earnings per share, that exclude certain charges that are described further in this presentation and in the reconciliation table of non-GAAP to GAAP information provided at the end of this presentation.

Management uses this non-GAAP information, along with GAAP information, in evaluating its historical operating performance. The non-GAAP information is not prepared in accordance with GAAP and may not be comparable to non-GAAP information used by other companies. The non-GAAP information should not be viewed as a substitute for, or superior to, other data prepared in accordance with GAAP.
