Explanatory Note

This Amendment No. 3 filed by Simcoe Partners, L.P., Simcoe Management Company, LLC, Jeffrey Jacobowitz and Elisheva Jacobowitz (the “Reporting Persons”), amends the Schedule 13D filed with respect to the common stock of Telular Corporation (the “Company”) by the Reporting Persons with the Securities and Exchange Commission on December 1, 2008, as amended (the “Original Schedule 13D”). This amendment amends and restates Item 5 of the Original Schedule 13D in its entirety.

Item 5.

Interest in the Securities of the Issuer

(a) As of May 12, 2010, Simcoe beneficially owns 900,000 shares of Common Stock of the Issuer, representing approximately 6.0% of the Issuer’s outstanding shares of Common Stock, which percentage is based upon the 14,949,792 shares of Common Stock issued and outstanding as of March 31, 2010 as reported in a press release filed with an 8-K filed by the Issuer with the Securities and Exchange Commission on May 4, 2010.

As the general partner of Simcoe, Simcoe Management may be deemed to beneficially own the 900,000 shares of Common Stock owned by Simcoe, representing approximately 6.0% of the outstanding shares.

As the manager of Simcoe Management, Jeffrey Jacobowitz may be deemed to beneficially own the 900,000 shares of Common Stock owned by Simcoe. Mr. Jacobowitz disclaims beneficial ownership of any such shares except to the extent of his pecuniary interest therein. In addition, Mr. Jacobowitz beneficially owns 130,600 shares of Common Stock, representing 0.9% of the outstanding shares, over which he has shared voting and dispositive power with his wife, Elisheva Jacobowitz.

Elisheva Jacobowitz beneficially owns 130,600 shares of Common Stock, representing 0.9% of the outstanding shares, over which she has shared voting and dispositive power with her husband, Jeffrey Jacobowitz.

Each of Simcoe, Simcoe Management and Jeffrey Jacobowitz may be deemed to have sole voting and dispositive power over the 900,000 shares of Common Stock reported as beneficially owned by such persons by virtue of each person’s relationship to the other as described in Item 2. Each may be deemed to have sole voting and dispositive power with respect to the shares each reports as beneficially owned by such person, regardless of the fact that multiple Reporting Persons within the same chain of ownership report sole voting and dispositive power with respect to such shares. Except to the extent expressly stated herein, each Reporting Person disclaims beneficial ownership of any shares of Common Stock beneficially owned by any other Reporting Person, in each case, except to the extent of such Reporting Person’s pecuniary interest therein.
