Termination and Amendment
The 2003 Plan will terminate by its terms and without any action by the Board on April 28, 2013. No awards may be made after that date. Awards outstanding on April 28, 2013 will remain valid in accordance with their terms.
Subject to certain limitations, the Compensation Committee may from time to time, alter, amend, suspend or terminate the 2003 Plan as it deems advisable. However, neither the Compensation Committee nor the Board will be able to amend the 2003 Plan, without the approval of the Stockholders, to increase the number of shares of common stock that may be the subject of awards granted under the 2003 Plan (except for certain adjustments necessary to prevent dilution or enlargements of benefits available under the 2003 Plan with respect to a recapitalization, merger, consolidation or similar corporate transaction affecting the shares of common stock underlying awards granted under the 2003 Plan). In addition, no amendments to or termination of the 2003 Plan shall in any way impair the rights of a participant under any award previously granted without such participant's consent.
