As previously reported, on April 17, 2012, Enova Systems Inc. (NYSE AMEX: ENA) (AIM: ENV) (AIM: ENVS) (the "Company") received notice (the "April Notice") from the NYSE Amex LLC (the "Exchange") indicating that the Company was not in compliance with one of the Exchange's continued listing standards as set forth in Part 10 of the Exchange's Company Guide (the "Exchange Guide"), and the Company was therefore subject to the procedures and requirements of Section 1009 of the Exchange Guide. Specifically, the Company was not in compliance with Section 1003(a) (iii) of the Exchange Guide because the Company reported stockholders' equity of less than $6,000,000 for 2011 and the Company had incurred a loss from continuing operations and/or net losses for five consecutive years. As required by the April Notice, the Company submitted a Plan of Compliance to the Exchange on May 17, 2012 addressing how the Company intends to regain compliance with the continuing listing standards of the Exchange Guide within a maximum of 18 months (the "Plan Period").

By letter dated May 22, 2012, the Company received an additional notice from the Exchange stating that a review of the Company's Form 10-Q for the first quarter of fiscal 2012 indicated that the Company does not meet an additional listing requirement. Specifically, the Company is not in compliance with Exchange Guide Section 1003(a)(ii) because the Company reported stockholders' equity of less than $4,000,000 and losses from continuing operations and/or net losses in three of its four most recent fiscal years.

Due to the higher stockholders' equity requirement identified in the April Notice, the Company is not required by the Exchange to submit an additional Plan of Compliance in connection with the deficiency identified in the notice dated May 22, 2012. If the Plan of Compliance is accepted but the Company is not in compliance with the continued listing standards of the Company Guide by October 15, 2013 or if the Company is not making progress consistent with the plan during the Plan Period, the Exchange staff will initiate delisting procedures as appropriate. In such event, the Company may appeal an Exchange staff determination to initiate delisting proceedings in accordance with Section 1010 and Part 12 of the Company Guide.
