Stockholder acknowledges that the intent of the foregoing sentence is to ensure that the Shares and any New Shares are voted in accordance with the terms hereof.

5. Share Legends. If so requested by Spansion, Stockholder agrees that the Shares and any New Shares shall bear a legend stating that they are subject to this Agreement.
