The terms and conditions of the Notes and related matters are set forth in the Indenture, dated as of November 9, 2010, by and between Spansion LLC, as issuer, the Company and Spansion Technology LLC, as guarantors, and Wells Fargo Bank, National Association, as trustee (the “Indenture”).

The Company will use its commercially reasonable efforts to cause the exchange offer registration statement to be declared effective by the SEC under the Securities Act and to consummate the exchange offer by no later than August 5, 2011. In certain circumstances, the Company may also be obligated to file a shelf registration statement in lieu of or in addition to the exchange offer registration statement. If the Company does not meet the above deadline (a “Registration Default”) then, subject to certain exceptions, the interest rate borne by the Notes will be increased by 0.25% per annum for the first 90 day period and thereafter by 0.50% per annum.
