|3. | Based on my knowledge, the financial statements, and other financial information included in this

| | (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

                  for external purposes in accordance with generally accepted accounting principles;

| | (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 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.
