Explanatory Note

As previously disclosed, on March 1, 2009, Spansion Inc. (the “Company”), Spansion Technology LLC, Spansion LLC, Cerium Laboratories LLC and Spansion International, Inc. (collectively, the “Debtors”) filed voluntary petitions in the United States Bankruptcy Court for the District of Delaware (the “Bankruptcy Court”) seeking relief under the provisions of Chapter 11 of Title 11 of the United States Code (the “Bankruptcy Code”). The Debtors continued to operate their businesses as debtors-in-possession under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code and the orders of the Bankruptcy Court.

On April 16, 2010, the Bankruptcy Court entered an order (the “Confirmation Order”) confirming and approving the Debtors’ Second Amended Joint Plan of Reorganization Dated April 7, 2010 (As Amended) (including all exhibits thereto, and as modified by the Confirmation Order, the “Plan”). A summary of the material features of the Plan, including the related rights offering (the “Rights Offering”) and financing arrangements, is contained in the Company’s Current Report on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) on April 22, 2010.

On May 10, 2010 (the “Effective Date”), the Plan became effective. The events described below occurred as a result of the consummation of the Plan.

On April 30, 2011, Spansion LLC (“Spansion”), a wholly owned subsidiary of the Company, entered into a Purchase Agreement (the “Agreement”) with SL Capital Appreciation Fund, L.L.C., Silver Lake Sumeru Fund, L.P. and Silver Lake Credit Fund, L.P. (collectively, the “Sellers”) to purchase all rights (the “Assigned Rights”) with respect to certain claims against the Debtors under the Chapter 11 Cases held by the Sellers. The aggregate purchase price to be paid by Spansion for the Assigned Rights is approximately $29.0 million.

Completion of the transactions contemplated by the Agreement will be consummated after entry of an order of the Bankruptcy Court under the Chapter 11 Cases approving the Agreement and the transactions thereunder.

The preceding description of the Agreement is qualified in its entirety by reference to the full text of the Agreement, which the Company intends to file as an exhibit to the Company’s Quarterly Report on Form 10-Q for the fiscal quarter ending June 26, 2011.

Messrs. Ajay Shah and Paul Mercadante, who are members of the Board of Directors of the Company, are each Managing Directors of Silver Lake Sumeru, an entity which is affiliated with the Sellers. Both Messrs. Shah and Mercadante recused themselves from voting when the Board of Directors approved entering into the Agreement.

On the Effective Date, the Company reserved for issuance 46,247,760 unregistered shares of the Company’s Class A Common Stock, par value $0.001 per share (the “Class A Common Stock”), to satisfy the allowed claims of certain unsecured creditors, as specified in the Plan, except for (1) certain classes of unsecured creditors as specified in the Plan, (2) holders of claims up to $2,000, who will receive cash for their claims, and (3) distributions to the holders of the exchangeable debentures of Spansion LLC, whose distributions are instead to be made to the holders of the senior notes of Spansion LLC in accordance with the subordination provisions of the exchangeable debentures.
