1.    
          I have reviewed this Form 10-Q of the Company;

2.    
          Based on my knowledge, this report does not contain any untrue statement of a
          material fact or omit to state a material fact necessary to make the statements
          made, in light of the circumstances under which such statements were made, not
          misleading with respect to the period covered by this report;

3.    
          Based on my knowledge, the financial statements, and other financial information
          included in this report, fairly present in all material respects the financial

          the periods presented in this report;

4.    
          I am 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 Company and have:

a.       
          Designed such disclosure controls and procedures, or caused such disclosure
          controls and procedures to be designed under my supervision, to ensure that
          material information relating to the Company is made known to me 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 my 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 Companys disclosure controls and
          procedures and presented in this report my 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 Companys internal control over
          financial reporting that occurred during the Companys most recent fiscal
          quarter (the Companys fourth fiscal quarter in the case of an annual
          report) that has materially affected, or is reasonably likely to materially
          affect, the Companys internal control over financial reporting; and

5.    
          I have disclosed, based on my most recent evaluation of internal control over
          financial reporting, to the Companys auditors and the audit committee of
          the Company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 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.
