 the year of the “disqualifying disposition” equal to the excess of the fair market value of the shares on the date the participant exercised the option over the exercise price, and any amount the participant realizes above the fair market value of the shares on the date of exercise will be treated as capital gain.

If the amount the participant realizes in a “disqualifying disposition” is less than the fair market value of the shares on the date of exercise but greater than the exercise price, the participant will recognize ordinary income equal to the excess (if any) of the amount realized in the disposition over the exercise price, unless the disposition is a type of transaction in which the participant may not recognize loss for tax purposes (for example, a sale between certain related persons or a gift).

If the amount the participant realizes in a “disqualifying disposition” is less than the exercise price, the participant will not be required to recognize ordinary income and will be entitled to recognize a capital loss equal to the difference between the amount realized and the exercise price, unless the disposition is a type of transaction in which the participant may not recognize loss for tax purposes.

To the extent the participant receives shares that are equal in number to the shares surrendered, the participant’s holding period for the acquired shares will include the holding period for the surrendered shares, except for purposes of determining whether the participant has made a “disqualifying disposition.” Any shares the participant receives in excess of the number of shares the participant surrenders will have a holding period that begins on the date of exercise.

For purposes of determining whether the participant has made a “disqualifying disposition,” all shares the participant receives when the participant exercises the ISO will be subject to both the one-year and two-year holding periods described above. The time the participant held the surrendered shares will
