system of internal accounting controls as required by MI 52-109. The Company has established disclosure controls and procedures as required by MI

Reports, there have been no significant changes in the Companys internal disclosure controls and procedures or its internal control over
financial reporting (as such terms are defined in Section 1.1 of MI 52-109) or, to the Companys knowledge, in other factors that could

differ from the foregoing, the Company is in compliance with all such requirements, except as would not have a Material Adverse Effect.
