        This Amendment No. 1 amends and supplements the Schedule 13D (the "Schedule 13D") originally filed with the Securities and Exchange Commission on August 29, 2003 by Cubic Corporation, a Delaware corporation ("Cubic") and CDA Acquisition Corporation, a Delaware corporation and wholly owned subsidiary of Cubic ("CDA"), relating to (i) the Agreement and Plan of Merger, dated as of August 20, 2003 (the "Merger Agreement") by and among Cubic, CDA and ECC International Corp (the "Issuer"), and (ii) those certain Stockholder Tender Agreements by and between Cubic and certain stockholders of the Issuer (the "Stockholders"), who were affiliates of the Issuer (the "Stockholder Tender Agreements").

        The Merger Agreement provides for, among other things, (i) the offer by CDA to purchase all the outstanding shares of common stock, par value $0.10 per share, of the Issuer at a price of $5.25 per share, net to the seller in cash, without interest thereon, upon the terms and subject to the conditions set forth in the Offer to Purchase, dated August 27, 2003, and the related Letter of Transmittal (which together with any amendments or supplements thereto, collectively constitute the "Offer") and (ii) the subsequent merger of CDA with and into the Issuer (the "Merger"), with the Issuer surviving the Merger as a wholly owned subsidiary of Cubic. The Stockholder Tender Agreements provide for, among other things, the tender pursuant to the Offer by each Stockholder and certain of their affiliates, of all of their shares of Issuer common stock, as well as any additional shares of Issuer common stock that they may acquire.

Item 4. Purpose of the Transaction

        At midnight, New York City time on September 24, 2003, the Offer expired. On September 25, 2003, in accordance with the Merger Agreement, CDA accepted for payment 7,399,138 shares of Issuer common stock (approximately 93.3% of all outstanding shares) in the Offer. After the expiration of the Offer, CDA commenced a subsequent offering period (the "Subsequent Offering Period") which began at 9:00 a.m., New York City time, on September 25, 2003, and will expire at 5:00 p.m., New York City time, on October 10, 2003. During the Subsequent Offering Period, CDA will accept for payment all shares of Issuer common stock that are validly tendered at a price of $5.25 per share and promptly pay for such shares of Issuer common stock after such shares are tendered. Through September 30, 2003, CDA had accepted for payment 18,383 additional shares of Issuer common stock (approximately 0.3% of all outstanding shares) pursuant to the Subsequent Offering Period. After the expiration of the Subsequent Offering Period, Cubic, CDA and Issuer will proceed, as promptly as practicable, to complete the Merger, pursuant to which CDA will acquire the remaining outstanding shares of Issuer common stock for $5.25 per share in cash, subject to appraisal rights. Pursuant to the terms of the Merger Agreement, effective upon acceptance of and payment for the shares of Issuer common stock pursuant to the Offer, Cubic designated four persons who were appointed to Issuer's board and who constitute a majority of the total number of directors on Issuer's board. If the Merger is consummated, (i) Issuer will become a wholly-owned subsidiary of Cubic, (ii) the Certificate of Incorporation of Issuer will be amended and restated, (iii) the bylaws of Issuer will be replaced with the bylaws of CDA, and (iv) the directors and officers of CDA will become the directors and officers of Issuer, as the surviving corporation in the Merger.

Item 5. Interest in Securities of the Issuer

        As a result of CDA's acceptance of 7,417,521 shares of Issuer common stock upon expiration of the Offer and pursuant to the Subsequent Offering Period, CDA acquired beneficial ownership of all those shares or approximately 93.6% of Issuer's total outstanding shares. CDA has sole voting and dispositive power with respect to such shares.
