|   | 3. | Based          on my knowledge, the financial statements, and other financial information          included in this report, fairly present in all material respects the          financial condition, results of operations and cash flows of the registrant          as of, and for, the periods presented in this report; |
|--------|----|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | 4. | The          registrant’s other certifying officer(s) and I are responsible          for establishing and maintaining disclosure controls and procedures          (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) and internal          control over financial reporting (as defined in Exchange Act Rules 13a-15(f)          and 15d-15(f)) for the registrant and have: |
|--------|----|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | a. | Designed          such disclosure controls and procedures, or caused such disclosure controls          and procedures to be designed under our supervision, to ensure that          material information relating to the registrant, including its consolidated          subsidiaries, is made known to us by others within those entities, particularly          during the period in which this report is being prepared; |
|--------|----|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | b. | Designed          such internal control over financial reporting, or caused such internal          control over financial reporting to be designed under our supervision,          to provide reasonable assurance regarding the reliability of financial          reporting and the preparation of financial statements for external purposes          in accordance with generally accepted accounting principles; |
|--------|----|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | c. | Evaluated          the effectiveness of the registrant’s disclosure controls and procedures          and presented in this report our conclusions about the effectiveness          of the disclosure controls and procedures, as of the end of the period          covered by this report based on such evaluation; and |
|--------|----|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | d. | Disclosed          in this report any change in the registrant’s internal control          over financial reporting that occurred during the registrant’s          most recent fiscal quarter (the registrant’s fourth fiscal quarter          in the case of an annual report) that has materially affected, or is          reasonably likely to materially affect, the registrant’s internal          control over financial reporting; and |
|--------|----|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | 5. | The          registrant’s other certifying officer(s) and I have disclosed,          based on our most recent evaluation of internal control over financial          reporting, to the registrant’s auditors and the audit committee          of the registrant’s board of directors (or persons performing the          equivalent functions): |
|--------|----|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | 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 registrant’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 registrant’s internal control          over financial reporting. |
