Deferral. The Committee may defer payment of Awards, or any portion thereof, to Covered Employees as the Committee, in its discretion, determines to be necessary or desirable to preserve the deductibility of such amounts under Section 162(m). In addition, the Committee, in its sole discretion, may permit a Participant to defer receipt of the payment of cash that would otherwise be delivered to a Participant under the Plan. Any such deferral elections shall be subject to such rules and procedures as shall be determined by the Committee in its sole discretion.
