Bonus amounts under the 2009 Executive Bonus Plan are based on Quicksilver's performance for the year relative to the performance targets and weightings so established. The Compensation Committee has discretion to adjust a named executive officer's potential award or awards based on qualitative individual performance measures; provided that the discretion may be used only to reduce or eliminate a potential award.
