2.  Amendment to Section 2(b).  The first three sentences of Section 2(b) of the Agreement are hereby deleted and replaced with the following:

“The 2013-2015 Time-Vested Restricted Shares shall vest, and the Repurchase Option with respect to such vested 2013-2015 Time-Vested Restricted Shares shall lapse, in three equal installments on each of the first three anniversaries of the 2013-2015 Reference Date, subject to the continued employment of the Grantee with the Company through the applicable anniversary.  For the purposes of this Agreement, the “2013-2015 Reference Date” shall be January 20, 2012.  In addition, if (i) the Grantee’s employment with the Company shall be terminated by the Company without Cause (as defined in the LTIP) or (ii) a Change in Control (as defined below) shall occur, then any unvested 2013-2015 Time-Vested Restricted Shares shall become fully vested, and the Repurchase Option with respect thereto shall lapse, as of the date of such termination or the date of the consummation of such Change in Control, as the case may be.  The 2013-2015 Time-Vested Restricted Shares, to the extent unvested, may not be sold, assigned, transferred, pledged, hypothecated or otherwise disposed of, except by will or the laws of descent and distribution.”
