The Board at any time, and from time to time, may amend or terminate this Plan. However, except as provided in Section 11 relating to adjustments upon changes in Common Stock, Section 13.3 and Section 14.2 , no amendment shall be effective unless approved by the stockholders of the Company to the extent stockholder approval is necessary to satisfy any applicable law or securities exchange listing requirements. At the time of such amendment, the Board shall determine, upon advice from counsel, whether such amendment will be contingent on stockholder approval.
