Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On May 17, 2012, at the 2012 Annual Meeting of Shareholders (the “2012 Annual Meeting”) of LoJack Corporation (the “Company”), the Company’s shareholders approved an amendment and restatement of the Company’s 2008 Stock Incentive Plan (the “2008 Plan”). Pursuant to the amendment and restatement, the 2008 Plan was amended primarily to:

In addition, to ensure that certain awards (including cash bonuses) granted under the 2008 Plan to a “Covered Employee” (as defined in the Internal Revenue Code of 1986, as amended (the “Code”)) qualify as “performance-based” compensation under Section 162(m) of the Code, the 2008 Plan provides that the Compensation, Organization and Succession Committee of the Company’s Board of Directors may require that vesting of such awards be conditioned on the satisfaction of certain performance criteria described in the 2008 Plan. The Committee will select the particular performance criteria within 90 days following the commencement of a performance cycle. Subject to adjustments for stock splits and similar events, the maximum award granted to any individual in any year will not exceed 400,000 shares of the Company’s common stock. If the performance-based award is payable in cash to any Covered Employee, it cannot exceed $2 million for any performance cycle.

The 2008 Plan is included as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference. A detailed summary of the 2008 Plan is set forth in the Company’s definitive proxy statement filed with the Securities and Exchange Commission (the “SEC”) on April 5, 2012 (the “Proxy Statement”) under the caption “Proposal No. 2 - Amendment and Restatement of the LoJack Corporation 2008 Stock Incentive Plan.” Such description is incorporated herein by reference and is qualified in its entirety by reference to the full text of the 2008 Plan.

Also, as previously disclosed in the Company’s Current Report on Form 8-K filed with the SEC on November 8, 2011, Richard T. Riley retired as an employee from the Company as of the date of the 2012 Annual Meeting and resigned from his position as Executive Chairman of the Board of Directors. On May 17, 2012, the Board of Directors elected Rory J. Cowan to serve as the non-executive Chairman of the Board. As the non-executive Chairman, Mr. Cowan’s principal duties, in addition to his regular duties as a director, will be to preside at all meetings of the directors, to coordinate the agenda for the Board meetings with the President and Chief Executive Officer, to convene and preside at meetings of the independent directors and to perform such other non-executive Board administrative duties as the Board may from time to time determine. Mr. Cowan, who formerly served in the role of Lead Director, has been determined by the Board to be “independent” based on the application of the Company’s independence standards and under applicable rules and regulations of the SEC and the NASDAQ Global Select Market.
