Item 1.01  Entry into a Material Definitive Agreement.

On February 25, 2013, Cubic Corporation (NYSE “CUB”) (“Cubic”) entered into a Registration Rights Agreement (the “Agreement”) with Zable Survivor’s Trust dated September 18, 1978, Zable Marital QTIP Trust dated September 18, 1978, Zable Reverse QTIP Marital Trust dated September 18, 1978, and Zable Trust dated September 18, 1978 (the “Shareholders”), pursuant to which Cubic granted, subject to certain conditions and limitations, registration rights to the Shareholders with respect to their shares of Cubic common stock. In addition, for offerings effected in connection with the following rights, Cubic has agreed to indemnify the selling Shareholders and the underwriters, except with respect to certain information provided by them.

Subject to specified limitations, the Shareholders may require that Cubic register all or a portion of their registrable securities for sale under the Securities Act of 1933, as amended (the “Securities Act”), on a Form S-1 registration statement. Cubic is obligated to effect one such registration on Form S-1, but has also agreed to effect one additional registration on Form S-1 under specified circumstances. The Shareholders are also entitled to certain Form S-3 registration rights, commencing on the date that Cubic becomes eligible to register securities on Form S-3. In addition, if at any time Cubic proposes to register any of its securities under the Securities Act for sale to the public, except with respect to registration statements on Forms S-4, S-8 or another form not available for registering the sale of Cubic’s common stock to the public for cash, the Shareholders are entitled to notice of such registration and are entitled to include their shares of common stock in the registration, subject to certain limitations.

The foregoing summary of the Agreement is qualified in its entirety by the terms of the Agreement, which is attached as Exhibit 4.1 hereto and incorporated herein by reference.
