Shares Subject to the Plan
The Board of Trustees has reserved 60,000 shares for issuance under the 2008 Plan, subject to adjustment to reflect any increase or decrease in the number of issued shares resulting from a share split, share consolidation, share dividend or similar change in the capitalization of PREIT. Restricted shares that are forfeited to PREIT before they are fully vested will remain available for future grants.
The following table shows the aggregate number of shares that could be received by PREITs non-employee trustees pursuant to the plan.
