The Company has established disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the Company and designed such disclosure controls and procedures to ensure that material information relating to the Company is made known to the Company’s certifying officers by others within the Company, particularly during the period in which the Company’s Form 10-K or 10-Q, as the case may be, are being prepared. The Company’s certifying officers have evaluated the effectiveness of the Company’s controls and procedures as of the end of the reporting period covered by the Company’s Form 10-K and each of the Company’s Forms 10-Q filed with the Commission (each such date, the “Evaluation Date”) and presented in each such report their conclusions about the effectiveness of the Company’s disclosure controls and procedures based on their evaluations as of the applicable Evaluation Date. Since the Evaluation Date of the Company’s most recently filed Form 10-K or Form 10-Q, there have been no significant changes in the Company’s disclosure controls and procedures, the Company’s internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) or 15d-15(f)) or, to the Company’s knowledge, in other factors that could significantly affect the Company’s internal controls over financial reporting.
