Amendment to Merger Agreement

        On December 13, 2007, Saifun Semiconductors Ltd. (“Saifun”) and Spansion Inc. (“Spansion”) issued a joint press release announcing that the boards of directors of each of Spansion and Saifun have approved, and Spansion and Saifun have executed, an amendment to their merger agreement providing for an approximately $31.4 million increase in the cash distribution, which would result in a cash distribution of approximately $6.05 per share in cash based on Saifun’s current capitalization. The cash distribution will be funded solely from Saifun’s existing cash on hand prior to or on the closing of the transaction. The exchange ratio that each outstanding share of Saifun common stock would receive in the merger remains 0.7429 shares of Spansion common stock. In connection with this amendment, Saifun will send to Saifun shareholders and file with the Securities and Exchange Commission additional solicitation materials.
