Explanatory Notes:

This Amendment No. 1 amends and supplements the Schedule 13D, filed jointly by the Reporting Persons on December 3, 2014 (the “Original Statement”). Unless otherwise indicated, all capitalized terms used herein shall have the same meaning as set forth in the Original Statement. Except as set forth below, there are no changes to the information set forth in the Original Statement.

Item 2. Identity and Background.

On December 31, 2014, a Reporting Person, PTES Acquisition Corp., merged with and into PTES Acquisition II Corp., with PTES Acquisition II Corp. as the surviving entity. Accordingly, PTES Acquisition II Corp. is a successor by merger to PTES Acquisition Corp.

Item 4. Purpose of the Transaction.

Item 4 of the Original Statement is hereby supplemented as follows:

On December 31, 2014, the Reporting Persons caused the Issuer to be merged with and into PTES Acquisition II Corp., a Nevada corporation and a wholly-owned subsidiary of the Reporting Persons, pursuant to Section 92A.180 of the Nevada Revised Statutes and that certain Plan and Agreement of Merger, dated as of December 31, 2014, by and between the Issuer and PTES Acquisition II Corp., a Nevada corporation and a wholly-owned subsidiary of Pioneer Power Solutions, Inc., with PTES Acquisition II Corp. as the surviving entity (the “Merger”). Prior to the Merger, the Reporting Persons had completed the acquisition of 100% of the Series D Convertible Preferred Stock from 24 individual stockholders and owned 96% of the outstanding shares of the Issuer’s capital stock entitled to vote on a merger.

Upon the effectiveness of the Merger, the Issuer ceased to exist as a separate entity, and each outstanding share of the Issuer’s common stock was cancelled and converted into the right to receive the merger consideration of $0.0007 per share of the Issuer’s common stock. As a result of the Merger, the Issuer ceased to be a public reporting company and its common stock is no longer quoted for trading.

SIGNATURE

After reasonable inquiry and to the best of my knowledge and belief, I certify that the information set forth in this statement is true, complete and correct.
