[1] 25% of the issued shares vested immediately upon issuance.  In general, the remaining shares vest 25% on the first through third anniversaries of the date of issuance (subject to continuous employment through the applicable vesting date).

[2] On April 18, 2012, the Company entered into amended and restated employment agreements with the Company’s executive officers.  To induce the executives to agree to the substantial reduction in benefits upon certain terminations following a change of control as described in the agreements, the Company awarded an aggregate of 1,035,595 restricted common shares to the executives pursuant to the 2012 Plan.  None of these restricted common shares will vest prior to the third anniversary of the date of issuance.  Thereafter, 33.3% of each award of restricted common shares will vest on each of the third, fourth and fifth anniversaries of the date of issuance.  Vesting will accelerate upon a change of control or if the relevant executive’s employment with the Company were to terminate for any reason other than for cause (as defined in the agreements).
