      Discussion of Forward-Looking Statements
    
    
      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 in the merger (“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. Factors may also include the costs and 
      expenses of developing, maintaining and protecting intellectual 
      property, including judgments or settlements paid or received in 
      connection with intellectual property or employment or other litigation 
      and their related costs, and certain financial risks, including the 
      possibility of future losses and negative cash flow from operations, 
      risks of obtaining financing and risks of the resulting leverage, as 
      well as interest and currency rate fluctuations.
    
    
      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 
      screen-assisted, 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.
    
    
      We believe that all forward-looking statements are based upon reasonable 
      assumptions when made. However, we caution that it is impossible to 
      predict actual results or outcomes or the effects of risks, 
      uncertainties or other factors on anticipated results or outcomes and 
      that accordingly you should not place undue reliance on these 
      statements. Forward-looking statements speak only as of the date when 
      made and we undertake no obligation to update these statements in light 
      of subsequent events or developments.
