[1] Reflects the grant of restricted shares to our executive officers.

[2] Reflects the grant of performance share units (“PSUs”) to our executive officers. The estimated fair value of the PSUs on grant date was determined using a Monte Carlo simulation model. The PSUs provide for an award based on the performance of our common stock over a three-year period with the maximum award being 200% of the original awarded PSUs and the minimum amount being zero. The vested PSUs will be settled in an equivalent number of shares of our common stock unless the Compensation Committee of our Board of Directors elects to pay in cash.

[3] Reflects the grant of restricted shares to certain members of our Board of Directors who have made an election to take their quarterly fees in stock in lieu of cash.
