Purpose of the separation Sony aims to strengthen its business in the rapidly expanding optical disc drive market through the timely delivery of highly reliable and competitive products. By partitioning our optical disc drive business and merging with the optical disc drive operations of NEC, we believe that the technological and human resources strengths of both companies will be maximized and the new joint venture company will make an effective and speedy business start. 2. Overview of the separation (1) Schedule of the separation February 27, 2006 Approval of separation plan April 1, 2006 Date of separation April 3, 2006 Registration of separation *Pursuant to the provisions of Clause 1 of Article 374-6 of the Commercial Code, Sony shall perform the separation without approval of the separation agreement by its shareholders. **Consummation of the establishment the joint venture company remains subject to approvals of any governmental or regulatory authorities required in Japan and other countries. (2) Method of the separation 1. Method Sony will separate a part of its business and the new company, Sony NEC Optiarc Inc. will take over the separated part of the business. 2. Reason for adopting this method This method was chosen because it was determined to be the most efficient means by which to transfer the relevant business. (3)Allocation of shares The new company will issue 40,000 shares of common stock, and will allocate 22,000 shares to Sony and 18,000 shares to NEC. (4) Rights and obligations to be taken over by the new company The following items (i) and (ii) will be taken over by the new company.

(5) Prospects of paying debt obligations Based on the projected financial statement as of September 30, 2005, both Sony and new company have significantly more assets than liabilities. Additionally, both companies are expected not to post any significant matters from their operations after the separation that are serious enough to affect their financial capability to pay their respective debt obligations.
