LoJack Corporation 2003 Stock Incentive Plan

Stock Option Agreement

This Stock Option Agreement and the preceding Certificate of Stock Option Grant (“Version 1”) (the “Certificate” and together with this document, the “Option Agreement”) made as of the date stated on the Certificate (the “Grant Date”) by and between LoJack Corporation, a Massachusetts corporation (the “Company”), and the Optionee.

WITNESSETH THAT:

WHEREAS, the Company has instituted the LoJack Corporation 2003 Stock Incentive Plan (the “Plan”); and

WHEREAS, the Stock Incentive Plan Subcommittee of the Compensation Committee (the “Committee”) has authorized the grant of a stock option upon the terms and conditions set forth below and pursuant to the Plan, a copy of which is attached hereto and incorporated herein;

NOW, THEREFORE, in consideration of the premises and the mutual covenants and agreements herein contained and for other good and valuable consideration the receipt and adequacy of which are hereby acknowledged, the Company and the Optionee agree as follows.

1. Grant. Subject to the terms of the Plan and this Option Agreement, the Company hereby grants to the Optionee a stock option (the “Option”) to purchase from the Company the amount of Common Stock (“Stock”) shown on the Certificate under “Option to Purchase.” If so provided in the “Type of Option” shown on the Certificate, this Option is intended to constitute an incentive stock option and to qualify for special federal income tax treatment under Section 422 of the Code.

2. Grant Price. This Option may be exercised at the “Grant Price” per share shown on the Certificate, subject to adjustment as provided herein and in the Plan.

3. Term and Exercisability of Option. This Option shall expire on the “Grant Expiration Date” shown on the Certificate, unless the Option expires earlier pursuant to this Section 3 or any provision of the Plan. At any time before its expiration, this Option may be exercised to the extent vested, as shown on the Certificate, provided that:

(a) at the time of exercise the Optionee is not in violation of any Employee Confidentiality and Non-Competition Agreement with the Company;

(b) the Optionee’s employment, contractual or other service relationship with the Company (“Relationship”) must be in effect on a given date in order for any scheduled increment in vesting, as set forth in the “Vesting Schedule” on the Certificate, to become effective; and

(c) except as otherwise provided in the Plan, this Option may not be exercised after the ninetieth (90th) day following the date of termination of the Relationship between the

Optionee and the Company, except that if the Relationship terminates by reason of the Optionee’s death or total and permanent disability (as determined by the Board on the basis of medical advice satisfactory to it), the unexercised portion of the Option that is otherwise exercisable on the date of termination of the Relationship shall remain exercisable thereafter for one (1) year.

For purposes of this Section 3, the term “Company” refers to the Company and all Subsidiaries.

4. Method of Exercise. Prior to its expiration and to the extent that the right to purchase shares of Stock has vested hereunder, this Option may be exercised from time to time by notice acceptable to the Company stating the number of shares with respect to which this Option is being exercised and accompanied by payment of the option price by certified or bank check or money order or, with the approval of the Committee, as otherwise provided in Section 5(c) of the Plan. The Company, or the Committee, may from time to time designate one or more forms or methods of providing notice of the exercise of an Option and in that event the Optionee agrees to utilize such form or method. As soon as practicable after its receipt of such notice, the Company shall, without transfer or issue tax to the Optionee (or other person entitled to exercise this Option), deliver to the Optionee (or other person entitled to exercise this Option), at the principal executive offices of the Company or such other place as shall be mutually acceptable, a stock certificate or certificates for such shares out of theretofore authorized but unissued shares or reacquired shares of its Stock as the Company may elect; provided, however, that the time of such delivery may be postponed by the Company for such period as may be required for it with reasonable diligence to comply with any applicable requirements of law. If the Optionee (or other person entitled to exercise this Option) fails to pay for and accept delivery of all of the shares specified in such notice upon tender of delivery thereof, his right to exercise this Option with respect to such shares not paid for may be terminated by the Company.

5. Withholding Taxes. The Optionee hereby agrees, as a condition to any exercise of this Option, to provide to the Company an amount sufficient to satisfy the Company’s obligation to withhold federal, state, local and other taxes arising by reason of such exercise (the “Withholding Amount”), if any, by (a) authorizing the Company and/or any Subsidiary to withhold the Withholding Amount from his cash compensation or (b) remitting the Withholding Amount to the Company in cash; provided, however, that to the extent that the Withholding Amount is not provided by one or a combination of such methods, the Company may at its election withhold from the Stock that would otherwise be delivered upon exercise of this Option that number of shares having a Fair Market Value on the date of exercise sufficient to eliminate any deficiency in the Withholding Amount; and provided, further, that the Fair Market Value of Stock withheld shall not exceed an amount in excess of the minimum required withholding.

6. Non-assignability of Option. During the life of the Optionee, this Option shall be exercisable only by him, by a conservator or guardian duly appointed for him by reason of the Optionee’s incapacity or by the person appointed by the Optionee in a durable power of attorney acceptable to the Company’s counsel. This Option shall not be assignable or transferable by the Optionee except by will or by the laws of descent and distribution or as permitted by the Committee in its discretion pursuant to the third sentence of Section 5(i) or Section 6 of the Plan.

7. Compliance with Securities Act; Lock-Up Agreement. The Company shall not be obligated to sell or issue any shares of Stock or other securities pursuant to the exercise of this Option unless the shares of Stock or other securities with respect to which this Option is being exercised are at that time effectively registered or exempt from registration under the Securities Act and applicable state

securities laws. In the event shares or other securities shall be issued that shall not be so registered, the Optionee hereby represents, warrants and agrees that he will receive such shares or other securities for investment and not with a view to their resale or distribution, and will execute an appropriate investment letter satisfactory to the Company and its counsel. The Optionee further hereby agrees that as a condition to the purchase of shares upon exercise of this Option, he will execute an agreement in a form acceptable to the Company to the effect that the shares shall be subject to any underwriter’s lock-up agreement in connection with a public offering of any securities of the Company that may from time to time apply to shares held by officers and employees of the Company, and such agreement or a successor agreement must be in full force and effect.

8. Legends. The Optionee hereby acknowledges that the stock certificate or certificates evidencing shares of Stock or other securities issued pursuant to any exercise of this Option may bear a legend setting forth the restrictions on their transferability described in Section 7 hereof, if such restrictions are then in effect.

9. Rights as Stockholder. The Optionee shall have no rights as a stockholder with respect to any shares covered by this Option until the date of issuance of a stock certificate to him for such shares. No adjustment shall be made for dividends or other rights for which the record date is prior to the date such stock certificate is issued.

10. Termination or Amendment of Plan. The Board may terminate or amend the Plan at any time. No such termination or amendment will affect rights and obligations under this Option, to the extent it is then in effect and unexercised.

11. Effect Upon Employment and Performance of Services. Nothing in this Option or the Plan shall be construed to impose any obligation upon the Company or any Subsidiary to employ or utilize the services of the Optionee or to retain the Optionee in its employ or to engage or retain the services of the Optionee.

12. Time for Acceptance. Unless the Optionee shall evidence his acceptance of this Option by electronic or other execution of the Certificate within thirty (30) days after its delivery to him, the Option shall be null and void.

13. Notice of Disqualifying Disposition. If the Option is designated under “Type of Option” as an ISO, the Optionee agrees to notify the Company promptly in the event that he sells, transfers, exchanges or otherwise disposes of any shares of Stock issued upon exercise of the Option before the later of (a) the second anniversary of the date of grant of the Option and (b) the first anniversary of the date the shares were issued upon his exercise of the Option.

14. Right of Repayment. In the event that the Optionee accepts employment with or provides services for a competitor of the Company within two (2) years after the date of exercise of this Option or any portion of it, the Optionee shall pay to the Company an amount equal to the excess of the Fair Market Value of the Stock as of the date of exercise over the price paid for such shares; provided, however, that the Committee in its discretion may release the Optionee from the requirement to make such payment, if the Committee determines that the Optionee’s acceptance of such employment or performance of such services is not inimical to the best interests of the Company. The Company may deduct the amount of payment due under the preceding sentence from any compensation or other amount payable by the Company to the Optionee. For purposes of this Section 14, the term “Company” refers to the Company and all Subsidiaries.
