| | -- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | a) | Designed such disclosure controls and procedures, or caused such disclosure
          controls and procedures to be designed under our supervision, to ensure that

               of the small business issuers board of directors (or persons performing
               the equivalent functions):
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | a) | All significant deficiencies and material weaknesses in the design or operation
          of internal controls over financial reporting which are reasonably likely to
          adversely affect the small business issuer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 small business issuers internal control
          over financial reporting.
