“As the Director of the Company or the top Management of the Finance and
Accounting Division, I have revised this Annual Information Disclosure
document with caution and certify that the information disclosed
herewith is complete, accurate, truthful, does not mistake and no
essential element is missing. In addition, I hereby certify that:

(1) The Financial Statements and Financial Information summarized in the
Annual Report display accurate and complete essential element on the
financial status, performance and cash flows of the Company and its
subsidiary.

(2) I am responsible for ensuring that the Company has a good
information disclosure system and that essential element of the Company
and its subsidiary is disclosed accurately and completely. I am also
responsible for ensuring compliance with such system.

(3) I am responsible for ensuring that the Company has a good internal
    control system and that it complies with such system. I reported the
    information about the internal control assessment on February 22,
    2007 to the Company’s auditor and the Audit Committee. This
    assessment included any default, change and misconduct which may
    affect the reporting of the Company and its subsidiary’s Financial
    Statements.

Therefore, as evidence that these documents constitute the entire set
that I have certified, I have authorized Mrs. Duangthip Eamrungroj to
initial all pages. If any page is without Mrs. Duangthip Eamrungroj’s
initial, I do not certify that the information given is the true copy.”
