                 Inc.
| | -- | ----------------------------------------------------------------------------------------------------

| | 2. | Based on my knowledge, this quarterly report does not contain any untrue
               statement of 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 registrant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 registrant and we have:
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (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 quarterly report is being prepared;
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (b) | evaluated the effectiveness of the registrants disclosure controls and
                    procedures and presented in this quarterly report our conclusions about the
                    effectiveness of the disclosure controls and procedures, as of the end of the
                    period covered by this quarterly report; and
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (c) | 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 that has materially affected, or is reasonably likely to
                    materially affect, the registrants internal control over financial
                    reporting.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 5. | The registrants other certifying officers 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 registrants board of
                    directors (or persons performing the equivalent function):
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (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.
