Safe Harbor
This written communication contains “forward-looking statements” made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. In some cases, you can identify forward-looking statements by words such as “may,” “hope,” “will,” “should,” “expect,” “plan,” “anticipate,” “intend,” “believe,” “estimate,” “predict,” “potential,” “continue,” “could,” “future” or the negative of those terms or other words of similar meaning. You should carefully read forward-looking statements, including statements that contain these words, because they discuss our future expectations or state other “forward-looking” information. Forward-looking statements are subject to numerous assumptions, risks and uncertainties which change over time. ICE and NYSE Euronext caution readers that any forward-looking statement is not a guarantee of future performance and that actual results could differ materially from those contained in the forward-looking statement.
Forward-looking statements include, but are not limited to, statements about the benefits of the proposed merger involving ICE and NYSE Euronext, including future financial results, ICE’s and NYSE Euronext’s plans, objectives, expectations and intentions, the expected timing of completion of the transaction and other statements that are not historical facts. Important factors that could cause actual results to differ materially from those indicated by such forward-looking statements are set forth in ICE’s and NYSE Euronext’s filings with the U.S. Securities and Exchange Commission (the “SEC”). These risks and uncertainties include, without limitation, the following: the inability to close the merger in a timely manner; the inability to complete the merger due to the failure of NYSE Euronext stockholders to adopt the merger agreement or the failure of ICE stockholders to approve the issuance of ICE common stock in connection with the merger; the failure to satisfy other conditions to completion of the merger, including receipt of required regulatory and other approvals; the failure of the proposed transaction to close for any other reason; the possibility that any of the anticipated benefits of the proposed transaction will not be realized; the risk that integration of NYSE Euronext’s operations with those of ICE will be materially delayed or will be more costly or difficult than expected; the challenges of integrating and retaining key employees; the effect of the announcement of the transaction on ICE’s, NYSE Euronext’s or the combined company’s respective business relationships, operating results and business generally; the possibility that the anticipated synergies and cost savings of the merger will not be realized, or will not be realized within the expected time period; the possibility that the merger may be more expensive to complete than anticipated, including as a result of unexpected factors or events; diversion of management’s attention from ongoing business operations and opportunities; general competitive, economic, political and market conditions and fluctuations; actions taken or conditions imposed by the United States and foreign governments or regulatory authorities; and adverse outcomes of pending or threatened litigation or government investigations. In addition, you should carefully consider the risks and uncertainties and other factors that may affect future results of the combined company, as are described in the section entitled “Risk Factors” in the joint proxy statement/prospectus filed by ICE with the SEC, and as described in ICE’s and NYSE Euronext’s respective filings with the SEC that are available on the SEC’s web site located at www.sec.gov, including the sections entitled “Risk Factors” in ICE’s Form 10-K for the fiscal year ended December 31, 2012, as filed with the SEC on February 6, 2013, and “Risk Factors” in NYSE Euronext’s Form 10-K for the fiscal year ended December 31, 2012, as filed with the SEC on February 26, 2013. You should not place undue reliance on forward-looking statements, which speak only as of the date of this written communication. Except for any obligations to disclose material information under the Federal securities laws, ICE undertakes no obligation to publicly update any forward-looking statements to reflect events or circumstances after the date of this written communication.

What to Expect - Product and Exchange Operating Model
Post-closing we will look to ensure that the markets for the Liffe soft commodity contracts are stable, well managed, liquid markets that facilitate the convergence of the futures market to the cash market
US-based contracts will remain traded and cleared in the US
London-based soft contracts (coffee, sugar and cocoa) will remain traded and cleared in London
Other European commodity contracts (e.g. Milling Wheat) will be included in potential Euronext IPO
London-based soft contracts clearing will have transitioned from LCH to ICE Clear Europe in mid-2013
Institute product committees for Liffe Coffee, Sugar and Cocoa, similar to those that ICE Futures U.S. operate. Committees will be consulted with respect to:
Shorten/align trading hours
Address cash-futures convergence issues (e.g. quality terms -premiums & discounts, grading and warehousing provisions)
Identify appropriate trading currency for cocoa
Develop new contracts and efficient arbitrage vehicles
Design strategy to maximize collateral efficiency
