It is possible that other executive officers and Directors of the Company may enter into similar stock trading plans in the future.  Except as may be required by law, the Company does not undertake to report on stock trading plans by other Company officers or Directors, nor report modifications, terminations or other activities under Mr. Perry’s Plan or the plan of any other individual.
