AGREEMENT AND PLAN OF MERGER

This Agreement and Plan of Merger ("Agreement") is made and entered into as of August 20, 2003, by and among: Cubic Corporation, a Delaware corporation ("Parent"); CDA Acquisition Corporation, a Delaware corporation and a wholly owned subsidiary of Parent ("Acquisition Sub"); and ECC International Corp., a Delaware corporation (the "Company"). Certain capitalized terms used in this Agreement are defined in Exhibit A.

RECITALS

A. The Boards of Directors of Parent, Acquisition Sub and the Company have each determined that it is in the best interests of their respective stockholders for Parent to acquire the Company upon the terms and subject to the conditions set forth herein.

B. It is proposed that Acquisition Sub make a cash tender offer (the "Offer") to acquire all of the outstanding shares of Company Common Stock (the "Shares") for $5.25 per share (such amount, or any greater amount per share paid pursuant to the Offer, being the "Per Share Amount"), net to the seller in cash, upon the terms and subject to the conditions of this Agreement.

C. In furtherance of the acquisition of the Company by Parent, the Boards of Directors of Parent, Acquisition Sub and the Company have each approved a merger (the "Merger") of Acquisition Sub with and into the Company, with the Company as the surviving corporation (the "Surviving Corporation"), upon the terms and subject to the conditions hereof.

D. The Board of Directors of the Company has, in light of and subject to the terms and conditions hereof, resolved to recommend that the stockholders of the Company tender their shares pursuant to the Offer.

E. In order to induce Parent and Acquisition Sub to enter into this Agreement and to consummate the Transaction, concurrently with the execution and delivery of this Agreement certain stockholders of the Company are executing agreements to tender their shares of Company Common Stock and to vote against certain transactions (the "Stockholder Tender Agreements") in favor of Parent and Acquisition Sub.

AGREEMENT

The parties to this Agreement, intending to be legally bound, agree as follows:

Section 1. THE OFFER

1.1 The Offer.

(a) Provided that none of the events set forth in Annex I shall have occurred or are continuing (other than the requirements set forth in clauses "(i)," "(ii)," "(iii)(e)" and "(iii)(f)" of Annex I), as promptly as practicable after the date of this Agreement (but in no event more than five business days after the public announcement of the execution of this Agreement), Acquisition Sub shall commence (within the meaning of Rule 14d-2 under the Exchange Act) the Offer.

(b) The obligation of Acquisition Sub to accept for payment and to pay for any shares of Company Common Stock tendered pursuant to the Offer shall be subject only to (i) the condition that there shall be validly tendered a number of shares of Company Common Stock which, together with any outstanding shares of Company Common Stock with respect to which Parent has sole beneficial ownership, represents at least a majority of the Fully Diluted Number of Company Shares (the "Minimum Condition") and (ii) the other conditions set forth in Annex I. Acquisition Sub expressly reserves the right to increase the Per Share Amount or to make any other changes in the terms and conditions of the Offer not inconsistent with the

provisions of this Agreement; provided, however, that without the prior written consent of the Company, (i) the Minimum Condition may not be amended or waived; and (ii) no change may be made that changes the form of consideration to be paid, decreases the price per share of Company Common Stock or the number of shares of Company Common Stock sought in the Offer, imposes conditions to the Offer in addition to those set forth in Annex I, or extends the expiration date of the Offer beyond the initial expiration date of the Offer (except as provided in (c), below). Notwithstanding anything to the contrary contained in this Agreement, the Offer may not be withdrawn prior to the expiration date (or any rescheduled expiration date) of the Offer.

(c) The Offer shall initially be scheduled to expire 20 business days following the commencement thereof. If, at any then-scheduled expiration date, the conditions to the Offer have not been satisfied or waived (other than conditions which are not capable of being satisfied), Acquisition Sub shall be entitled to extend the Offer for such amount of time as Acquisition Sub reasonably believes is necessary to cause such Offer conditions to be satisfied; provided, however, that Acquisition Sub shall not be entitled to extend the Offer to any date occurring after 60 business days following the commencement of the Offer without the prior written consent of the Company. Notwithstanding anything to the contrary contained in this Agreement: (i) Acquisition Sub may, without the consent of the Company or any other Person (A) extend the Offer for any period required by any rule or regulation of the SEC applicable to the Offer and (B) if more than a majority of the Fully Diluted Number of Company Shares but less than 90% of the Fully Diluted Number of Company Shares shall have been validly tendered pursuant to the Offer as of the scheduled or extended expiration date, extend the Offer for an additional period of not more than 20 business days, provided, however, that Acquisition Sub shall not be entitled to extend the Offer pursuant to this clause (B) to any date occurring after 60 business days following the commencement of the Offer without the prior written consent of the Company; and (ii) Acquisition Sub may, without the consent of the Company or any other Person, elect to provide for a subsequent offering period (and one or more extensions thereof) pursuant to, and in accordance with the terms of, Rule 14d-11 under the Exchange Act.

(d) As promptly as practicable on the date of commencement of the Offer, Parent and Acquisition Sub shall (i) file with the SEC a Tender Offer Statement on Schedule TO with respect to the Offer that will contain or incorporate by reference the offer to purchase and form of the related letter of transmittal and (ii) cause the offer to purchase and related documents to be disseminated to holders of shares of Company Common Stock. Parent and Acquisition Sub agree that they shall cause the Schedule TO and all exhibits, amendments or supplements thereto (which together constitute the "Offer Documents") filed by either Parent or Acquisition Sub with the SEC to comply in all material respects with the Exchange Act and the rules and regulations thereunder and other applicable laws (except that Parent and Acquisition Sub shall have no obligation with respect to any information in the Offer Documents supplied by the Company or its Representatives in writing). Each of Parent, Acquisition Sub and the Company agrees to respond promptly to any comments of the SEC or its staff and to promptly correct any information provided by it for use in the Offer Documents if and to the extent that such information shall have become false or misleading in any material respect, and Parent further agrees to take all steps necessary to cause the Offer Documents as so corrected to be filed with the SEC and the other Offer Documents as so corrected to be disseminated to holders of shares of Company Common Stock, in each case as and to the extent required by applicable federal securities laws. The Company shall promptly furnish to Parent and Acquisition Sub all information concerning the Acquired Corporations and the Company's stockholders (i) that may be required in connection with any action contemplated by this Section 1.1(d) within two business days after the public announcement of

the execution of this Agreement and (ii) reasonably requested in connection with any action contemplated by this Section 1.1(d) within two business days after such request. The Company and its counsel shall be given reasonable opportunity to review and comment on the Offer Documents prior to the filing thereof with the SEC. Parent and Acquisition Sub agree to provide the Company and its counsel with any comments Parent, Acquisition Sub or their counsel may receive from the SEC or its staff with respect to the Offer Documents promptly after receipt of such comments.

1.2 Company Actions.

(a) The Company hereby consents to the Offer and represents that its Board of Directors, at a meeting duly called and held, has (i) by the unanimous vote of all directors of the Company, determined that this Agreement and the transactions contemplated hereby, including the Offer and the Merger, are fair to and in the best interests of the Company's stockholders, (ii) by unanimous vote of all directors of the Company, approved and adopted this Agreement and the transactions contemplated hereby, including the Offer and the Merger, in accordance with the requirements of the DGCL, (iii) by unanimous vote of all directors of the Company declared that this Agreement is advisable and (iv) by unanimous vote of all directors of the Company, resolved to recommend that stockholders of the Company accept the Offer and tender their shares of Company Common Stock pursuant to the Offer and adopt this Agreement and approve the Merger (the recommendation of the Company's Board of Directors that the stockholders of the Company accept the Offer and tender their shares of Company Common Stock pursuant to the Offer and adopt this Agreement and approve the Merger being referred to as the "Company Board Recommendation").

(c) As promptly as practicable on the day that the Offer is commenced, the Company shall file with the SEC and disseminate to holders of shares of Company Common Stock, in

each case as and to the extent required by applicable federal securities laws, a Solicitation/Recommendation Statement on Schedule 14D-9 (together with any exhibits, amendments or supplements thereto, the "Schedule 14D-9") that, subject to Section 1.2(b), shall reflect the Company Board Recommendation. The Company agrees that it shall cause the Schedule 14D-9 to comply in all material respects with the Exchange Act and the rules and regulations thereunder and other applicable laws (except that the Company shall have no obligation with respect to any information in the Schedule 14D-9 supplied by Parent or Acquisition Sub or their Representatives in writing). Each of Parent, Acquisition Sub and the Company agrees to respond promptly to any comments of the SEC or its staff and to promptly to correct any information provided by it for use in the Schedule 14D-9 if and to the extent that such information shall have become false or misleading in any material respect, and the Company further agrees to take all steps necessary to cause the Schedule 14D-9 as so corrected to be filed with the SEC and to be disseminated to holders of shares of Company Common Stock, in each case as and to the extent required by applicable federal securities laws. Parent and its counsel shall be given reasonable opportunity to review and comment on the Schedule 14D-9 and any amendment thereto prior to the filing thereof with the SEC. The Company agrees to provide Parent and its counsel with any comments the Company or its counsel may receive from the SEC or its staff with respect to the Schedule 14D-9 promptly after receipt of such comments.

(d) The Company shall promptly furnish Parent with a list of its stockholders, mailing labels and any available listing or computer file containing the names and addresses of all record holders of shares of Company Common Stock and lists of securities positions of shares of Company Common Stock held in stock depositories, in each case true and correct as of the most recent practicable date, and shall provide to Parent such additional information (including updated lists of stockholders, mailing labels and lists of securities positions) and such other assistance as Parent may reasonably request in connection with the Offer. Parent and Acquisition Sub and their agents shall hold in confidence the information contained in any such labels, listings and files, shall use such information only in connection with the Offer and the Merger and, if this Agreement shall be terminated, shall, upon request, deliver, and shall use their reasonable efforts to cause their agents to deliver, to the Company (or destroy) all copies and any extracts or summaries from such information then in their possession or control.

The Company shall take all action necessary to cause Parent's designees to be elected or appointed to the Company's Board of Directors, including increasing the number of directors and seeking and accepting resignations of incumbent directors. At such time, to the extent requested by Parent, the Company shall also cause individuals designated by Parent to constitute at least the same percentage (rounded up to the next whole number) on (i) each committee of the Board and (ii) each Board of Directors of each Subsidiary of the Company (and each committee thereof) as the number of directors designated by Parent represents on the Company's Board of Directors; provided that if Parent and/or Acquisition Sub acquires 85% or more of the shares of the Company Common Stock outstanding then Parent shall be entitled to designate all members of (i) each committee of the Board and (ii) each Board of Directors of each Subsidiary of the Company (and each committee thereof).

(b) The Company's obligations to appoint Parent's designees to the Company's Board of Directors shall be subject to Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder.

The

Merger shall become effective upon the date and time of the filing of such certificate of merger with the Secretary of State of the State of Delaware (the "Effective Time").

(a) the Certificate of Incorporation of the Surviving Corporation shall be amended and restated immediately after the Effective Time to conform to Exhibit B;

(b) the Bylaws of the Surviving Corporation shall be amended and restated as of the Effective Time to conform to the Bylaws of Acquisition Sub as in effect immediately prior to the Effective Time; and

(c) the directors and officers of the Surviving Corporation immediately after the Effective Time shall be the respective individuals who are directors and officers of Acquisition Sub immediately prior to the Effective Time.

2.5 Conversion of Shares.

(a) At the Effective Time, by virtue of the Merger and without any further action on the part of Parent, Acquisition Sub, the Company or any stockholder of the Company:

(i) any shares of Company Common Stock then held by the Company or any wholly owned Subsidiary of the Company (or held in the Company's treasury) shall be canceled and retired and shall cease to exist, and no consideration shall be delivered in exchange therefor;

(ii) any shares of Company Common Stock then held by Parent, Acquisition Sub or any other wholly owned Subsidiary of Parent shall be canceled and retired and shall cease to exist, and no consideration shall be delivered in exchange therefor;

(iii) except as provided in clauses "(i)" and "(ii)" above and subject to Section 2.5(b), each share of Company Common Stock then outstanding (other than any Dissenting Shares, as defined below) shall be converted into the right to receive the Per Share Amount (the "Merger Consideration"), without interest;

(iv) each share of the common stock, $0.001 par value per share, of Acquisition Sub then outstanding shall be converted into one share of common stock of the Surviving Corporation; and

(v) all then outstanding Company Options shall be terminated.

(b) If, between the date of this Agreement and the Effective Time, the outstanding shares of Company Common Stock are changed into a different number or class of shares by reason of any stock split, division or subdivision of shares, stock dividend, reverse stock split, consolidation of shares, reclassification, recapitalization or other similar transaction, then the Merger Consideration shall be appropriately adjusted.

2.6 Surrender of Certificates; Stock Transfer Books.

(a) Prior to the Effective Time, Parent shall designate a bank or trust company reasonably acceptable to the Company to act as agent (the "Paying Agent") for the holders of shares of Company Common Stock to receive the funds to which holders of such shares shall become entitled pursuant to Section 2.5. Such funds shall be invested by the Paying Agent as directed by the Surviving Corporation.

(b) Promptly after the Effective Time, the Surviving Corporation shall cause to be mailed to each Person who was, at the Effective Time, a holder of record of shares of Company Common Stock entitled to receive the Merger Consideration pursuant to Section 2.5 a form of

letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the certificates evidencing such shares (the "Certificates") shall pass, only upon proper delivery of the Certificates to the Paying Agent) and instructions for use in effecting the surrender of the Certificates pursuant to such letter of transmittal. Upon surrender to the Paying Agent of a Certificate, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other documents as may be required pursuant to such instructions, the holder of such Certificate shall be entitled to receive in exchange therefor the Merger Consideration for each share of Company Common Stock formerly evidenced by such Certificate, and such Certificate shall then be canceled. No interest shall accrue or be paid on the Merger Consideration payable upon the surrender of any Certificate for the benefit of the holder of such Certificate. If the payment equal to the Merger Consideration is to be made to a Person other than the Person in whose name the surrendered Certificate formerly evidencing shares of Company Common Stock is registered on the stock transfer books of the Company, it shall be a condition of payment that the Certificate so surrendered shall be endorsed properly or otherwise be in proper form for transfer and that the Person requesting such payment shall have paid all transfer and other similar Taxes required by reason of the payment of the Merger Consideration to a Person other than the registered holder of the Certificate surrendered, or shall have established to the satisfaction of the Surviving Corporation that such Taxes either have been paid or are not applicable.

(c) At any time following the sixth month after the Effective Time, the Surviving Corporation shall be entitled to require the Paying Agent to deliver to it any funds which had been made available to the Paying Agent and not disbursed to holders of shares of Company Common Stock (including, without limitation, all interest and other income received by the Paying Agent in respect of all funds made available to it), and, thereafter, such holders shall be entitled to look to the Surviving Corporation (subject to abandoned property, escheat and other similar laws) only as general creditors thereof with respect to any Merger Consideration that may be payable upon due surrender of the Certificates held by them. Notwithstanding the foregoing, neither the Surviving Corporation nor the Paying Agent shall be liable to any holder of a share of Company Common Stock for any Merger Consideration delivered in respect of such share to a public official pursuant to any abandoned property, escheat or other similar law.

(d) At the close of business on the day of the Effective Time, the stock transfer books of the Company with respect to the shares of Company Common Stock shall be closed and thereafter there shall be no further registration of transfers of shares of Company Common Stock on the records of the Company. From and after the Effective Time, the holders of shares of Company Common Stock outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such shares except as otherwise provided herein or by applicable law.

(e) The Surviving Corporation, Parent and Acquisition Sub shall be entitled to deduct and withhold (or cause the Paying Agent to deduct and withhold) from the Merger Consideration payable to any holder of shares of Company Common Stock or Company Options such amounts as it is required by any Legal Requirement to deduct and withhold with respect to Taxes. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the shares of Company Common Stock or Company Options in respect of which such deduction and withholding was made.

2.7 Appraisal Rights. If the Merger is effectuated pursuant to Section 253 of the DGCL, shares of Company Common Stock outstanding immediately prior to the Effective Time and held

by a holder who is entitled to demand and properly demands appraisal for such shares of Company Common Stock in accordance with the DGCL (the "Dissenting Shares") shall not be converted into the right to receive Parent Common Stock, unless such holder fails to perfect or withdraws or otherwise loses his or her right to appraisal. If after the Effective Time such holder (a "Dissenting Stockholder") fails to perfect or withdraws or loses his or her right to appraisal, each such share of Company Common Stock shall be treated as if it had been converted as of the Effective Time into a right to receive the Merger Consideration without any interest thereon (less any amounts entitled to be deducted or withheld pursuant to Section 2.6(e)). The Company shall give Parent prompt notice of any demands received by the Company for appraisal of shares of Company Common Stock, and Parent shall have the right to participate in all negotiations and proceedings with respect to such demands. The Company shall not, without the prior written consent of Parent, make any payment with respect to, or settle or offer to settle, any such demands.

2.8 Further Action. If, at any time after the Effective Time, any further action is reasonably determined by Parent to be necessary or desirable to carry out the purposes of this Agreement or to vest the Surviving Corporation with full right, title and possession of and to all rights and property of Acquisition Sub and the Company, the officers and directors of the Surviving Corporation and Parent shall be fully authorized (in the name of Acquisition Sub, in the name of the Company and otherwise) to take such action.

6.5 Indemnification of Officers and Directors.

(a) All rights to indemnification existing in favor of those Persons who are directors and officers of the Company as of the date of this Agreement (the "Indemnified Persons") for their acts and omissions occurring prior to the Effective Time, as provided in the Company's bylaws (as in effect as of the date of this Agreement) and as provided in the indemnification agreements between the Company and said Indemnified Persons (as in effect as of the date of this Agreement) in the forms disclosed by the Company to Parent prior to the date of this Agreement, shall survive the Merger and shall be observed by the Surviving Corporation to the fullest extent available under Delaware law for a period of six years from the Effective Time, and any claim made requesting indemnification pursuant to such indemnification rights within such six-year period shall continue to be subject to this Section 6.5(a) and the indemnification rights provided under this Section 6.5(a) until disposition of such claim.
