(3) The restricted stock units vest, subject to continued employment with the Issuer through each vesting date, as to 1/6th of the units for each calendar year during 2013 - 2018 based on the achievement of total stockholder return hurdles on either a relative or an absolute basis for the applicable calendar year. If neither of the total stockholder return hurdles are achieved for an applicable year during the performance period, those units will remain eligible to vest in a subsequent year (ending on December 31, 2018) if the Issuer achieves a cumulative total stockholder return goal as of the end of that year.

If neither of the total stockholder return hurdles are achieved for an applicable year during the performance period, those units will remain eligible to vest in a subsequent year (ending on December 31, 2019) if the Issuer achieves a cumulative total stockholder return goal as of the end of that year.
