On August 3, 2015, SolarCity Corporation, a Delaware corporation (“SolarCity”), entered into a Stock Purchase Agreement (the “Agreement”) with Solar Explorer, LLC, a Delaware limited liability company and a wholly-owned subsidiary of SolarCity (“First Purchaser”), Solar Voyager, LLC, a Delaware limited liability company and a wholly-owned subsidiary of SolarCity (“Second Purchaser” and collectively with SolarCity and First Purchaser, “Purchasers”), ILIOSSON, S.A. de C.V., a joint stock corporation of variable capital formed and existing with the laws of Mexico (“ILIOSS”), and the stockholders of ILIOSS (“Sellers”), pursuant to which Purchasers are to acquire 100% of the capital stock of ILIOSS in exchange for (i) $9.5 million in cash, subject to adjustments as set forth in the Agreement (the “Closing Consideration”), (ii) an additional $5 million upon the successful achievement of a battery storage deployment milestone as set forth in the Agreement, subject to adjustments as set forth in the Agreement, and (iii) additional cash consideration based on megawatt deployments in Mexico from the closing date through December 31, 2019, subject to adjustments as set forth in the Agreement (the consideration payable pursuant to clauses (ii) and (iii) of the foregoing, the “Earnout Consideration”). The Earnout Consideration may become payable to the Sellers, if at all, following the achievement by the ILIOSS business unit of specified post-closing operations, and subject in each case to the continuing employment of the Sellers (or their designated affiliates). Following the Acquisition, ILIOSS continue to operate as a business unit of SolarCity.

The Agreement contains customary representations and warranties of each of Purchasers and Sellers. The representations and warranties of each party set forth in the Agreement have been made solely for the benefit of the other parties to the Agreement, and such representations and warranties should not be relied on by any other person. In addition, such representations and warranties (1) have been qualified by disclosure schedules that the parties have exchanged in connection with the execution of the Agreement, (2) are subject to the materiality standards set forth in the Agreement, which may differ from what may be viewed as material by investors, (3) in certain cases, were made as of a specific date, and (4) may have been used for purposes of allocating risk between the respective parties rather than establishing matters of fact. Accordingly, no person should rely on the representations and warranties as characterizations of the actual state of facts. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the execution of the Agreement.

Pursuant to the Agreement, following the consummation of the Acquisition, the Sellers have agreed to indemnify SolarCity, its officers, directors, affiliates, stockholders, employees, agents and representatives for any losses related to specified matters, including, among other things, inaccuracies, misrepresentations and breaches of representations or warranties of Sellers contained in the Agreement and related certificates or other instruments delivered by or on behalf of ILIOSS or Sellers, any failure by Sellers to perform or comply with any covenant applicable to them contained in the Agreement and related certificates or other instruments delivered by or on behalf of ILIOSS or Sellers, and for other customary matters.

The closing of the Acquisition is subject to customary closing conditions, and the Agreement contains certain termination rights for both SolarCity and Sellers. The parties intend to consummate the transaction as soon as practicable and currently anticipate that the closing will occur in early August, 2015.

The foregoing description of the Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Agreement. The Agreement is filed as Exhibit 2.1 hereto and incorporated herein by reference.
