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

|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 under which such statements
                    were made, not misleading with respect to the period covered by this quarterly
                    report;
|-- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|3. |  | Based on my knowledge, the financial statements, and other financial information
                    included in this quarterly report, fairly present in all material respects the
                    financial condition, results of operations and cash flows of the registrant as
                    of, and for, the periods presented in this quarterly report;
|-- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|4. |  | The small business issuers other certifying officers and I are responsible
                    for establishing and maintaining disclosure controls and procedures (as defined
                    in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the small business issuer 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 small business issuer, including its
                    consolidated subsidiaries, is made known to us by others within those entities,
                    particularly during the period in which this quarterly report is being prepared;
| | -- |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | b) |  | Evaluated the effectiveness of the small business issuer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 quarterly report based on such evaluation; and
| | -- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | c) |  | Disclosed in this quarterly report any change in the small business
                    issuers internal control over financial reporting that occurred during the
                    small business issuers most recent fiscal quarter (the small business
                    issuers fourth fiscal quarter in the case of an quarterly report) that has
                    materially affected, or is reasonably likely to materially affect, the small
                    business issuers internal control over financial reporting; and
| | -- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|5. |  | The small business issuers other certifying officers and I have disclosed,
                    based on our most recent evaluation of internal control over financial
                    reporting, to the small business issuers auditors and the audit committee
                    of small business issuers board of directors (or persons performing the
                    equivalent function):
|-- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | a) |  | All significant deficiencies and material weaknesses in the design or operation
                    of internal controls over financial reporting which are reasonable 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.
