|2. | Based on my knowledge, this quarterly report does not contain any untrue
          statements 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 quarterly

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

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

|4. | As the registrants certifying officer, I am responsible for establishing
          and maintaining disclosure controls and procedures (as defined in Exchange Act
          Rules 13a-14 and 15d-14) for the registrant and have:
|-- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | a) | designed such disclosure controls and procedures to ensure that material
               information relating to the registrant, including its consolidated subsidiaries,
               is made known to me by others within those entities, particularly during the
               period in which this quarterly report is being prepared;
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | b) | evaluated the effectiveness of the registrants disclosure controls and
               procedures as of a date within 90 days prior to the filing date of this
               quarterly report (the Evaluation Date); and
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | c) | presented in this quarterly report my conclusions about the effectiveness of the
               disclosure controls and procedures based on my evaluation as of the Evaluation
               Date.
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|5. |  | I
have disclosed, based on my most recent evaluation, to the registrants
          auditors and the registrants board of directors:
|-- |  | -------------------------------------------------------------------------------------------------------------------------------------

| | a) | all significant deficiencies in the design or operation of internal controls
               which could adversely affect the registrants ability to record, process,
               summarize and report financial data and have identified for the
               registrants auditors any material weaknesses in internal controls; and
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | b) | any fraud, whether or not material, that involves management or other employees
               who have a significant role in the registrants internal controls; and
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------

|6. | I have indicated in this quarterly report whether there were significant changes
          in internal controls or in other factors that could significantly affect
          internal controls subsequent to the date of my most recent evaluation, including
          any corrective actions with regard to significant deficiencies and material
          weaknesses.
