AMENDMENT TO THE 2006 OMNIBUS LONG TERM INCENTIVE PLAN

Exhibit 10(l)

AMENDMENT TO THE 2006 OMNIBUS LONG TERM INCENTIVE PLAN

The Company adopted the 2006 Omnibus Long-term Incentive Plan (“Plan”) in order to provide for a wide array of stock-based and other long-term incentives for its employees and members of the Board. Under this Plan, the Compensation Committee of the Board grants Deferred Stock Units (“DSUs”) to certain nonemployee members of the Board.

Under the terms of the DSU Agreements, in the event of death all non-forfeitable DSUs will be paid to the estate of the Participant. In order to provide flexibility for Participants in the designation of a beneficiary, the following amendment to the Plan is proposed that will permit a Participant to name a beneficiary other than the estate.
