|                              |   | (a) all significant deficiencies and material   weaknesses in the design or operation of internal control over financial   reporting which are reasonably likely to adversely affect the company’s   ability to record, process, summarize and report financial information; and |
|                              |   |   |
|                              |   | (b) any fraud, whether or not material, that   involves management or other employees who have a significant role in the   company’s internal control over financial reporting. |
