Item 1. Security and Issuer. The class of equity security to which this Schedule 13D relates is the common stock, $0.0001 par value (the "Common Stock"), of SeeBeyond Technology Corporation, a Delaware corporation (the "Issuer"). The principal executive offices of the Issuer are located at 800 E. Royal Oaks Drive, Monrovia, California, 91016. Item 2. Identity and Background. The name of the person filing this Schedule 13D is Sun Microsystems, Inc., a Delaware Corporation ("Sun"). The principal business of Sun is providing products and services for network computing, including network computing infrastructure solutions that comprise computer systems (hardware and software), network storage systems (hardware and software), support services, client solutions (formerly known as professional services) and knowledge services. Sun's principal executive offices are located at 4150 Network Circle, Santa Clara, California 95054. The name, citizenship, principal occupation and address of each executive officer and director of Sun are set forth in Schedule I, which is incorporated by reference herein. During the last five years, none of the persons or entities referred to in this Item 2 (including those persons listed on Schedule I) has been (i) convicted in a criminal proceeding (excluding traffic violations and similar misdemeanors) or (ii) a party to a civil proceeding or a judicial or administrative body of competent jurisdiction and as a result of such proceeding, was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws. Item 3. Source and Amount of Funds or Other Consideration. Sun has entered into a voting agreement, dated June 27, 2005, with each of the directors and executive officers of the Issuer, as described in more detail below. The voting agreements were entered into in consideration of the execution and delivery of the Merger Agreement (as defined in Item 4 below) and Sun did not pay any additional consideration in connection with the execution and delivery of the voting agreements. Item 4. Purpose of Transaction. On June 27, 2005, the Issuer, Sun and Big Bear Acquisition Corporation, a Delaware corporation and direct wholly-owned subsidiary of Sun ("AcquisitionCo"), entered into an Agreement and Plan of Merger (the "Merger Agreement") pursuant to which the Issuer will become a subsidiary of Sun. The Merger Agreement contemplates that AcquisitionCo will merge with and into the Issuer (the "Merger") and each share of the Issuer's Common Stock (the "Shares"), except for treasury shares and dissenting shares, will be converted into the right to receive $4.25 in cash per share (the "Merger Consideration") following the satisfaction or waiver of the conditions set forth in the Merger Agreement, including obtaining Issuer stockholder approval for the transactions contemplated thereby. In connection with the Merger Agreement, and as a condition and inducement to Sun's willingness to enter into the Merger Agreement, James T. Demetriades, Alexander Demetriades, H. Carvel Moore, Raymond J. Lane, John W. Buckley, Salah M. Hassanein, Steven A. Ledger and Barry J. Plaga (the "Principal Stockholders") entered into Voting Agreements with Sun, each dated as of June 27, 2005 (each a "Voting Agreement") with respect to all Shares over which each such Principal Stockholder exercises voting or investment power (as determined pursuant to Rule 13d-3 under the Securities Exchange Act of 1934, as amended) (collectively, the "Owned Shares"). The Owned Shares include any shares of the Issuer as to which a Principal Stockholder acquires beneficial ownership after the execution of the Voting Agreement. Pursuant to the Voting Agreements, each of the Principal Stockholders appointed Sun and any designee of Sun as such Principal Stockholder's proxy and attorney-in-fact to vote and act on each such Principal Stockholder's behalf and in each such Principal Stockholder's name, place and stead with respect to such Principal Stockholder's Owned Shares, at any annual, special or other meeting of the stockholders of the Issuer and at any adjournment or postponement of any such meeting and to act by written consent with respect to each such Principal Stockholder's Owned Shares. Each Principal Stockholder affirmed that the proxy is coupled with an interest and shall be irrevocable and agreed not to grant any subsequent proxy with respect to such Principal Stockholder's Owned Shares. Each Principal Stockholder further irrevocably and unconditionally agreed (i) to vote or consent, or cause to be voted or consented, the Owned Shares in favor of the Merger Agreement and the consummation of the Merger if Sun is unable to vote the Owned Shares at such meeting; (ii) to execute and deliver or cause to be executed and delivered any written consent in favor of the Merger with respect to all of the Owned Shares; and (iii) with respect to any Owned Shares, to vote or execute and deliver any written consent against any Acquisition Proposal (as defined in the Merger Agreement) or action that would be inconsistent with or frustrate the purposes of the Voting Agreement, the Merger Agreement or any of the transactions contemplated by the Merger Agreement. Each Principal Stockholder also agreed that he will not, without the prior written consent of Sun, (a) directly or indirectly, sell, transfer, pledge, assign or otherwise dispose of, or enter into any contract, option, commitment or other arrangement or understanding with respect to the disposition of, any of the Owned Shares or any securities convertible into or exchangeable for Shares, or (b) take any action that would prohibit, prevent or preclude such Principal Stockholder from performing his or its obligations under the Voting Agreement, including, without limitation, granting a power of attorney with respect to the Owned Shares, depositing the Owned Shares in a voting trust or entering into any other stockholder voting agreements with respect to the Owned Shares. Each Principal Stockholder further agreed that the Voting Agreement and each Principal Stockholder's obligations thereunder attached to the Owned Shares and shall be binding upon any person or entity to which legal or beneficial ownership of such Owned Shares may pass. The Voting Agreements (other than the Voting Agreements with James Demetriades) terminate on the earlier of (i) the closing of the Merger and (ii) the termination of the Merger Agreement in accordance with its terms. The Voting Agreements with James Demetriades terminates on the earlier of (i) the closing of the Merger and (ii) six months following the termination of the Merger Agreement in accordance with its terms; provided that the restrictions contained in such Voting Agreement shall apply only to 16,423,245 Shares after the termination of the Merger Agreement in accordance with its terms.
