| | 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 related to CNET, including its consolidated subsidiaries,
                    is made known to us by others within those entities, particularly during the

                    financial reporting that occurred during CNETs most recent fiscal quarter

| | a) | all significant deficiencies and material weaknesses in the design or operation
                    of internal controls over financial reporting, which are reasonably likely to
                    adversely affect CNETs ability to record, process, summarize and report
                    financial data; and
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | b) | any fraud, whether or not material, that involves management or other employees
                    who have a significant role in CNETs internal control over financial reporting.
