Nonqualified Deferred Compensation

Our Nonqualified Deferred Compensation Plan is available to all of our employees whose annual compensation is greater than $90,000, including the named executive officers. Of the named executive officers, only Mr. O’Keefe and Mr. Lacourciere have deferred compensation under the Nonqualified Deferred Compensation Plan, and only Mr. Lacourciere deferred compensation under the plan during 2006. Participants may defer up to 100% of base salary and bonus prior to the year in which the compensation will be earned. Participant deferrals are credited to an account, which may earn returns based on the participant’s selection from a list of hypothetical investments. The investments generally mirror those provided in our 401(k) plan. The allocation of hypothetical investments may be changed once each year. The Nonqualified Deferred Compensation Plan is unfunded and therefore subject to the claims of creditors. We do not make any matching contributions to the Nonqualified Deferred Compensation Plan.

Generally, account balances under the Nonqualified Deferred Compensation Plan may be paid at the earliest of termination of employment, normal retirement, early retirement, or becoming disabled as a lump sum or systematic installments over ten years. Account balances may be distributed prior to retirement only in the event of a financial hardship due to an unforeseeable emergency, but not in excess of the amount needed to meet the hardship. Distributions from the Nonqualified Deferred Compensation Plan to our officers cannot be made until at least six months after termination of employment.
