      Caution Regarding Forward-looking Statements
    
    
      This press release contains “forward-looking 
      statements” within the meaning of the Private 
      Securities Litigation Reform Act of 1995. Forward-looking statements may 
      be identified by words such as expects, anticipates, plans, believes, 
      estimates, will or words of similar meaning and include statements 
      regarding the plans and expectations for the future. The forward-looking 
      statements contained in this press release include statements about the 
      conduct of Freescale after the transaction and the anticipated timing of 
      the transaction. Forward-looking statements are based on management’s 
      current expectations and assumptions, which are subject to inherent 
      uncertainties, risks and changes in circumstances that are difficult to 
      predict and could cause actual outcomes to differ materially from the 
      expectations of Freescale and its management. For example, if SigmaTel’s 
      stockholders do not approve the transaction, or if the necessary 
      regulatory approvals are not obtained, the transaction will not be 
      consummated. The following factors, among others, could cause actual 
      results to differ materially from those described in the forward-looking 
      statements: risks associated with uncertainty as to whether the 
      transaction will be completed, costs and potential litigation associated 
      with the transaction, the failure to obtain SigmaTel’s 
      stockholder approval, the inability to obtain, or meet specific 
      conditions imposed for applicable regulatory approvals relating to the 
      transaction, the failure of either party to meet the closing conditions 
      set forth in the merger agreement, the extent and timing of regulatory 
      approvals and the risk factors discussed from time to time by the 
      company in reports filed with the Securities and Exchange Commission. We 
      urge you to carefully consider the risks which are described in Freescale’s 
      and SigmaTel’s filings with the Securities 
      and Exchange Commission (including Freescale’s 
      Registration Statement on Form S-4/A filed on June 22, 2007 and Freescale’s 
      and SigmaTel’s filings on Forms 10-K, 10-Q 
      and 8-K). SigmaTel undertakes no obligation to publicly update any 
      forward-looking statement, whether as a result of new information, 
      future developments or otherwise.
