Explanation of Responses:	
(1) 	Each restricted stock unit (RSU) represents a right to receive one share of the Issuer's common stock. This award represents RSUs received under the short-term incentive bonus plan which are fully vested upon grant. The award was assumed by Tesla in the merger and converted into fully vested restricted stock units representing a right to receive an aggregate of 328 shares of the Common Stock of Tesla.	
(2) 	These units do not expire.	
(3) 	Each restricted stock unit (RSU) represents a right to receive one share of the Issuer's common stock. The RSU, which vests in annual installments over 4 years beginning February 20, 2019, was assumed by Tesla in the merger and converted into restricted stock units representing a contingent right to receive an aggregate of 434 shares of the Common Stock of Tesla on the same terms and conditions (including with respect to vesting and exercisability) as were applicable to the RSU prior to the consummation of the merger.	
(4) 	Each market stock unit (MSU) represents a right to receive one share of the Issuer's common stock. The MSUs vest based on performance of the Company's common stock compared to the Nasdaq Composite Index over a period of three years. Depending on the level of performance actually achieved, the number of shares that may vest under this award will vary. The amount included in the table above represents the target number of shares which vest upon a change in control, and therefore vest in connection with the Merger Agreement and are assumed by Tesla in the merger and converted into fully vested restricted stock units representing a right to receive an aggregate of 434 shares of the Common Stock of Tesla.	
(5) 	Each restricted stock unit (RSU) represents a right to receive one share of the Issuer's common stock. The RSU, which vests in annual installments over 4 years beginning February 20, 2018, was assumed by Tesla in the merger and converted into restricted stock units representing a contingent right to receive an aggregate of 361 shares of the Common Stock of Tesla on the same terms and conditions (including with respect to vesting and exercisability) as were applicable to the RSU prior to the consummation of the merger.	
(6) 	Each market stock unit (MSU) represents a right to receive one share of the Issuer's common stock. The MSUs vest based on performance of the Company's common stock compared to the Nasdaq Composite Index over a period of three years. Depending on the level of performance actually achieved, the number of shares that may vest under this award will vary. The amount included in the table above represents the target number of shares which vest upon a change in control, and therefore vest in connection with the Merger Agreement and are assumed by Tesla in the merger and converted into fully vested restricted stock units representing a right to receive an aggregate of 458 shares of the Common Stock of Tesla.	
(7) 	Each restricted stock unit (RSU) represents a right to receive one share of the Issuer's common stock. The RSU, which vests in annual installments over 4 years beginning January 15, 2017, was assumed by Tesla in the merger and converted into restricted stock units representing a contingent right to receive an aggregate of 185 shares of the Common Stock of Tesla on the same terms and conditions (including with respect to vesting and exercisability) as were applicable to the RSU prior to the consummation of the merger.	
(8) 	Each restricted stock unit (RSU) represents a right to receive one share of the Issuer's common stock. The RSU, which vests in annual installments over 4 years beginning March 13, 2016, was assumed by Tesla in the merger and converted into restricted stock units representing a contingent right to receive an aggregate of 35 shares of the Common Stock of Tesla on the same terms and conditions (including with respect to vesting and exercisability) as were applicable to the RSU prior to the consummation of the merger.
