 market value of the shares on the date the participant exercises the option.

Surrendered Shares. If the participant tenders (or attests to the ownership of) shares to pay the exercise price under an NSO, the following rules apply: To the extent the participant receives shares that are equal in number to the shares surrendered, the participant’s tax basis in the shares the participant receives will equal the participant’s tax basis in the surrendered shares, subject to certain adjustments. Shares are treated as being surrendered if the participant attested to ownership of the shares to pay the exercise price. To the extent the participant receives shares in excess of the number of shares the participant surrendered, the participant will recognize ordinary income, at the time of exercise, equal to the fair market value of the additional shares reduced by any cash the participant pays as part of the purchase price (unless the additional shares are restricted shares). The participant’s tax basis in the additional shares will be the sum of the amount the participant recognizes as ordinary income and any cash the participant pays as part of the purchase price.

Disposition of Option Shares. If the participant disposes of shares acquired by the exercise of an NSO, the participant generally will recognize gain (or, under certain conditions, loss) in the year of the disposition. The gain (or loss) will equal the difference between the amount the participant realizes on the disposition and the participant’s tax basis in the shares.

Ordinarily, the participant’s gain (or loss) will be capital gain (or loss). As explained under “Capital Gain” below, the rate at which capital gain is taxed depends on how long the participant holds the shares before disposing of them. The holding period generally is measured from the date on which the participant exercised the NSO and received the shares (or, if the participant receives restricted shares, on the date for which the participant recognizes income with respect to the restricted shares). If the participant surrendered shares (by tendering or attesting ownership) in order to exercise an option and received an equal number of shares in return, the capital gain holding period for those shares will include the holding period for the shares the participant surrendered. If the participant received shares in addition to the shares the participant surrendered, the holding period for the additional shares will begin just after the participant exercised the NSO. The holding period for restricted shares, including restricted shares the participant acquires by exercising an option, is determined as described below.
