Termination Because of Total Disability. If an Optionees employment or other service relationship with the Company terminates because of a Total Disability, as defined below, then the Optionees vested Options (determined as of the termination) shall not expire (and any ISOs will not cease to be treated as ISOs) until the sooner of (i) the end of the 12-month period following such termination or (ii) the normal expiration date of the Option. For purposes of this Plan, Total Disability means a mental or physical impairment that (a) causes an individual to be unable to engage in any substantial gainful activity, after reasonable accommodation, and (b) is expected to result in death or has lasted or is expected to last for a continuous period of 12 months or more. The status of Total Disability will be determined by the Administrator and, if requested by the affected Optionee, two independent physicians, and shall be deemed to exist on the first day after the Administrator (and the two independent physicians, if applicable) reach the conclusion. The application of this Section 9.2 will not accelerate the vesting of Options.
