| 2.     | Based on my knowledge, this annual report    does not contain any untrue statement of a material fact or omit to state a    material fact necessary to make the statements made, in light of the    circumstances under which such statements were made, not misleading with    respect to the period covered by this annual report.  3. 
Based on my knowledge, the financial    statements, and other financial information included in this annual report,    fairly present in all material respects the financial condition, results of    operations and cash flows of the registrant as of, and for, the periods    presented in this annual report.  4. 
The registrant's other certifying officers    and I are responsible for establishing and maintaining disclosure controls    and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e))    for the registrant and we have:    a. 
designed such disclosure controls and    procedures, or    caused such disclosure controls and procedures to be designed under our    supervision, to ensure that material information    relating to the registrant, including its consolidated subsidiaries, is made    known to us by others within those entities, particularly during the period    in which this annual report is being prepared;     b. 
    evaluated the effectiveness of the registrant's disclosure controls and    procedures andpresented in this annual report    our conclusions about the effectiveness of the disclosure controls and    procedures, as of the end of the period covered by this    annual report based on such evaluation;    and    c. 
disclosed in this    annual report any change in the registrant's internal control over financial    reporting that occurred during the registrant's fourth fiscal quarter that    has materially affected, or is reasonably likely to materially affect, the    registrant's internal control over financial reporting.  5. 
The registrant's other certifying officers    and I have disclosed, based on    our most recent evaluation of internal control over    financial reporting, to the registrant's auditors    and the audit committee of the registrant's board of directors (or persons    performing the equivalent function):     a. 
all significant deficiencies    and material weaknesses in the design or operation of    internal controls over financial reporting which    are reasonably likely to adversely affect the    registrant's ability to record, process, summarize and report financial data    and have identified for the registrant's auditors any material weaknesses in    internal controls; and     b. 
any fraud, whether or not material, that    involves management or other employees who have a significant role in the    registrant's internal controls.           Date: February 25, 2005. "Dan Amadori" (signed)                        Dan Amadori    Chief Financial Officer |
