The information in this release contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Such statements are based upon current expectations that involve risks and uncertainties. Any statements contained herein that are not statements of historical fact may be deemed to be forward-looking statements. For example, words such as “may,” “will,” “should,” “estimates,” “predicts,” “potential,” “continue,” “strategy,” “believes,” “anticipates,” “plans,” “expects,” “intends” and similar expressions are intended to identify forward-looking statements.

The actual results of eSpeed, BGC or the combined company (“we”, “our” or the “combined  company”) and the outcome and timing of certain events may differ significantly from the expectations discussed in the forward-looking statements. Factors that might cause or contribute to such a discrepancy for eSpeed, BGC and/or the combined company include, but are not limited to, the combined company’s relationship with Cantor and its affiliates and any related conflicts of interests, competition for and retention of brokers and other managers and key employees, pricing and commissions and market position with respect to any of our products, and that of the combined company’s respective competitors, the effect of industry concentration and consolidation, and market conditions, including trading volume and volatility, as well as economic or geopolitical conditions or uncertainties.

Results may also be impacted by the extensive regulation of our respective businesses and risks relating to compliance matters, as well as factors related to specific transactions or series of transactions, including credit, performance and unmatched principal risk as well as counterparty failure.

Discrepancies may also result from such factors as the ability to enter new markets or develop new products, trading desks, marketplaces or services and to induce customers to use these products, trading desks, marketplaces or services, to secure and maintain market share, to enter into marketing and strategic alliances, and other transactions, including acquisitions, dispositions, reorganizations, partnering opportunities, and joint ventures, and the integration of any completed transactions, to hire new personnel, to expand the use of technology for screenassisted, voice-assisted and fully electronic trading and to effectively manage any growth that may be achieved. Results are also subject to risks relating to the proposed Merger,  separation of the BGC businesses and the relationship between the various entities, financial reporting, accounting and internal control factors, including identification of any material weaknesses in our internal controls, our ability to prepare historical and pro forma financial statements and reports in a timely manner, and other factors, including those that are discussed under “Risk Factors” in each of eSpeed’s Annual Report on Form 10-K for the year ended December 31, 2006 filed with the SEC on March 15, 2007 and BGC’s Registration Statement on Form S-1 filed with the SEC on February 8, 2007 (Registration No. 333-140531) to the extent applicable.
