For years beginning January 1, 2008 and January 1, 2009, prior to January 1 of each such Plan Year, an Eligible Employee may elect to make a Bonus Deferral Contribution with respect to any Bonus scheduled to be paid in the second succeeding calendar year.

For a fiscal year of the Company beginning on and after October 1, 2010, an Eligible Employee may elect to make a Bonus Deferral Contribution prior to the first day of such fiscal year with respect to any Bonus for the performance period of the Company’s fiscal year scheduled to be paid no later than December 15 of the next succeeding fiscal year.

For example, prior to January 1, 2009, an Eligible Employee may make a Bonus Deferral Contribution election with respect to any Bonus to be earned in 2009 that is scheduled to be paid in 2010. Prior to January 1, 2010, an Eligible Employee may make a Bonus Deferral Contribution election with respect to any Bonus for the performance period from January 1, 2010 through September 30, 2010.
