(1) The Common Stock reported in this item was granted under the Company's 2009 Long-Term Incentive Plan (the "GMLTP") on December 31, 2010 upon the cancellation of the Restricted Stock Units ("RSUs") granted to the employee on March 15, 2010. These shares were fully vested upon grant but are subject to restrictions on sale until March 15, 2013.
(2) The Common Stock reported in this item was granted under the GMLTP on December 31, 2010. These shares were fully vested upon grant but are subject to restrictions on transfer until December 31, 2013.
(3) The RSUs reported in this item were cancelled upon the issuance of the Common Stock reported above. The RSUs did not have an expiration or exercise date or a conversion or exercise price.

Pursuant to the terms of the GMLTP, each issued and outstanding RSU was automatically converted into three RSUs, so that the employee was credited with a total of 19,473 RSUs granted on March 15, 2010.
