To Brokers, Dealers, Commercial Banks, Trust Companies and Other Nominees:

We have been engaged by Lexus Acquisition Sub, Inc. (“Purchaser”), a Massachusetts corporation and a wholly-owned subsidiary of CalAmp Corp., a Delaware corporation (“CalAmp”), to act as Information Agent in connection with its offer to purchase all outstanding shares of common stock, par value $0.01 per share (the “Shares”), of LoJack Corporation, a Massachusetts corporation (“LoJack”), at $6.45 per Share, net to the seller in cash, without interest and less any applicable withholding taxes, upon the terms and subject to the conditions set forth in the Offer to Purchase dated February 16, 2016 (the “Offer to Purchase”) and the related letter of transmittal that accompanies the Offer to Purchase (the “Letter of Transmittal” which, together with the Offer to Purchase, as each may be amended or supplemented from time to time, collectively constitute the “Offer”).

Consummation of the Offer is conditioned upon, among other things, immediately prior to expiration of the Offer: (i) there being validly tendered and not withdrawn a number of Shares that, considered together with all other Shares then owned by CalAmp and its subsidiaries (including Purchaser), represents at least two-thirds (66 ⅔%) of the total number of outstanding Shares on a fully diluted basis; (ii) the applicable waiting period (or any extension thereof) or approval under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR Act"), or other antitrust laws having expired or been terminated or obtained; and (iii) no governmental body having enacted, issued, promulgated, enforced or entered any law or order that is then in effect and has the effect of enjoining or otherwise preventing or prohibiting the making of the Offer or consummation of the merger of Purchaser with and into LoJack pursuant to the Agreement and Plan of Merger, dated as of February 1, 2016. On February 12, 2016, the Federal Trade Commission granted early termination of the waiting period under the HSR Act applicable to the Offer and the Merger. With such early termination, the condition of the Offer relating to the expiration or termination of the HSR Act waiting period has been satisfied.

(the “Depositary”) for the Offer, or if the procedures for book-entry transfer cannot be completed, by the expiration of the Offer;

4. A form of letter which may be sent to your clients for whose accounts you hold Shares registered in your name or in the name of your nominee, with space provided for obtaining such clients’ instructions with regard to the Offer; and
