Effect of Exercise of Tandem Right. If a Stock Appreciation Right is issued in tandem with an Option, the exercise of the Stock Appreciation Right or the related Option will result in an equal reduction in the number of corresponding Shares subject to the Option or Stock Appreciation Right, as applicable, that were granted in tandem with such Stock Appreciation Right or Option.

Tandem Stock Option/Stock Appreciation Rights. A Stock Appreciation Right may be granted in tandem with a Stock Option, either at the time of grant or at any time thereafter during the term of the Stock Option. A tandem Stock Option/Stock Appreciation Right will entitle the holder to elect, as to all or any portion of the number of Shares subject to such Stock Option/Stock Appreciation Right, to exercise either the Stock Option or the Stock Appreciation Right, resulting in the reduction of the corresponding number of Shares subject to the right so exercised as well as the tandem right not so exercised. A Stock Appreciation Right granted in tandem with a Stock Option hereunder shall have a base price per Share equal to the Exercise Price of the Stock Option, will be vested and exercisable at the same time or times that a related Stock Option is vested and exercisable, and will expire no later than the time at which the related Stock Option expires.

Tandem Stock Appreciation Rights. Any Tandem Stock Appreciation Right may be granted at the same time as the related Option is granted. Any Tandem Stock Appreciation Right related to an Option may be exercised only when the related Option would be exercisable and the Fair Market Value of the Shares subject to the related Option exceeds the exercise price at which Shares can be acquired pursuant to the Option. In addition, if a Tandem Stock Appreciation Right exists with respect to less than the full number of Shares covered by a related Option, then an exercise or termination of such Option shall not reduce the number of Shares to which the Tandem Stock Appreciation Right applies until the number of Shares then exercisable under such Option equals the number of Shares to which the Tandem Stock Appreciation Right applies. Any Option related to a Tandem Stock Appreciation Right shall no longer be exercisable to the extent the Tandem Stock Appreciation Right has been exercised, and any Tandem Stock Appreciation Right shall no longer be exercisable to the extent the related Option has been exercised.

A Tandem Stock Appreciation Right granted in connection with an Incentive Stock Option # may be exercised at, and only at, the times and to the extent the related Incentive Stock Option is exercisable; # expires upon the termination of the related Incentive Stock Option; # may not exceed 100% of the difference between the exercise price of the related Incentive Stock Option and the Fair Market Value of the Shares subject to the related Incentive Stock Option at the time the Tandem Stock Appreciation Right is exercised (and otherwise does not have economic and tax consequences upon exercise that are more favorable than exercise of the option followed by an immediate sale of the related Shares); # may be exercised at, and only at, such times as the Fair Market Value of the Shares subject to the related Incentive Stock Option exceeds the exercise price of the related Incentive Stock Option; and # may be transferred at, and only at, the times and to the extent the related stock option is transferable. If a Tandem Stock Appreciation Right is granted, there shall be surrendered and canceled from the related option at the time of exercise of the Tandem Stock Appreciation Right, in lieu of exercise under the related option, that number of Shares as shall equal the number of Shares as to which the Tandem Stock Appreciation Right shall have been exercised.

Each Tandem Stock Appreciation Right shall be subject to the same terms and conditions as the related stock option, including limitations on transferability and vesting, and shall be exercisable only to the extent such option is exercisable and shall terminate or lapse and cease to be exercisable when the related option terminates or lapses. A Tandem Stock Appreciation Right may be granted at the time of the grant of the related stock option or, if the related stock option is a Nonqualified Stock Option, at any time thereafter during the term of the stock option.
