REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
 
 Internal ControlIntegrated Framework
     
    
    The Company did not maintain effective entity level controls and procedures to prevent
certain accounting entries from being recorded prior to formal documentation of the arrangements
being obtained.  Specifically, the Company lacked effective policies and procedures for the review
and recognition of revenue associated with certain sales contracts and the accurate recording of
that revenue. Additionally, the Company lacked effective policies and procedures to insure use
of an appropriate measurement date for the valuation of certain share-based payments. These
deficiencies resulted in more than a remote likelihood that a material misstatement of the annual
or interim financial statements would not be prevented or detected.
    
    The Company did not maintain effective policies and procedures related to the assessment
of reserves for possible liability arising from certain litigation matters.  These deficiencies

    The warrants issued in connection with the February 2003,
September 2005, December 2005, February 2006, May 2006, July 2006 and
October 2006 convertible issuances meet the criteria of EITF 00-19 for
equity classification, as they do not contain similar registration
rights obligations with respect to the underlying shares. Accordingly,
the conversion features do not require derivative accounting. The
September 2005, February 2006, May 2006, July 2006 and October 2006
issuances do have a beneficial conversion feature; however, the
February 2003 and December 2005 issuances have no beneficial
conversion feature. 17
