|  
|2. |  | Based on my knowledge, this quarterly 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

|  
|4. |  | The registrants other certifying officers and I are responsible for
establishing and maintaining disclosure controls and procedures (as
defined in Exchange Act Rules 13a-14 and 15d-14) for the registrant and

| | a) |  | designed such disclosure controls and procedures to ensure
that material information relating to the registrant, including its

those entities, particularly during the period in which this
quarterly report is being prepared;
| | -- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|

controls and procedures as of a date within 90 days prior to the

| | a) |  | all significant deficiencies in the design or operation of
internal controls which could adversely effect 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. |  | The registrants other certifying officers and I have indicated in
