In June 1984, Mr. Gonnella established Interamerican Trade Corporation (ITC). ITC established US subsidiaries for off-shore manufacturers of automotive parts and managed their distribution to OEM and aftermarket channels.

From June 1989 to August 1992, Mr. Gonnella was President of the Automotive Products Group of Amcast Industrial Corporation, which was a manufacturer of structural aluminum components for the US automotive industry. Here, Mr. Gonnella had full P&L responsibility and led multiple US-based manufacturing facilities.

Neither Mr. Gonnella nor Mr. Ford has yet been appointed to serve on any committees of our Board of Directors. We have not entered into any arrangements or understandings with either Mr. Gonnella or Mr. Ford, and there are no arrangements or understandings between Mr. Gonnella or Mr. Ford and any other person pursuant to which Mr. Gonnella or Mr. Ford were elected as directors. Other than as disclosed in the Form 8-K, there are no transactions in which Mr. Gonnella or Mr. Ford have an interest requiring disclosure under Item 404(a) of Regulation S-K.

As disclosed in the Form 8-K, prior to the Merger, Enerpulse granted Mr. Ford certain options in consideration for his service as a director of Enerpulse under an equity incentive plan. In substitution for the options granted under the Enerpulse plan that have been terminated, Mr. Ford has been granted options under our 2013 Equity Incentive Plan (the “Plan”), which Plan was adopted by the our Board of Directors in connection with the Merger. Immediately following the Merger, options to purchase 14,916 shares of our common stock, of which options to purchase 11,601 shares are fully vested, were granted to Mr. Ford under the Plan.
