Amendment and Termination. The Board may amend, suspend or terminate the Plan. However, the Company will obtain stockholder approval for any amendment to the Plan to the extent required to comply with applicable laws and New York Stock Exchange listing requirements.
Generally, no action by the Board or stockholders may alter or impair any outstanding award under the Plan without the written consent of the holder of such award. Unless we seek a stockholder-approved extension of the Plan term, awards may be granted under the Plan only until October 16, 2016.
