herewith is complete, accurate and truthful. I believe that it will not
cause any misunderstanding and does not omit any important information
that needs to be disclosed. Moreover, I also certify that :

accurate information regarding the performance and the cash flow of the
Company and its subsidiaries.

effective disclosure system that will assure the Company discloses all
true and important information of the Company and its subsidiaries and
for ensuring compliance.

communicated our internal control assessment as of December 31, 2003 to
the external auditor; this assessment included any default, change and

subsidiaries’ financial statements.
