2.4 Stock Appreciation Rights
2.4.1 Grant. Stock appreciation rights may be granted to eligible recipients in such number and at such times during the term of the Plan as the Committee may determine; provided, however, that the maximum number of shares of Common Stock as to which stock appreciation rights may be granted under the Plan to any eligible recipient in any one fiscal year may not exceed 150,000 shares (as adjusted pursuant to the provisions of Section 1.6.3).
2.4.2 Exercise Price. The exercise price per share with respect to each stock appreciation right will be determined by the Committee but will not be less than the Fair Market Value of the Common Stock. Unless otherwise noted in the Award Agreement, the Fair Market Value of the Common Stock will be its closing price on the New York Stock Exchange on the date of grant of the Award of stock appreciation rights.
2.4.3 Term of Stock Appreciation Right. In no event will any stock appreciation right be exercisable after the expiration of 10 years from the date on which the Stock Appreciation Right is granted.
2.4.4 Exercise of Stock Appreciation Right and Delivery of Shares. Each stock appreciation right may be exercised in such installments as may be determined in the Award Agreement at the time the stock appreciation right is granted. Subject to any limitations in the applicable Award Agreement, any stock appreciation rights not exercised on the applicable installment date may be exercised thereafter at any time before the final expiration of the stock appreciation right. To exercise a stock appreciation right, the Grantee must give written notice to NBTY specifying the number of stock appreciation rights to be exercised. Upon exercise of stock appreciation rights, shares of Common Stock with a Fair Market Value equal to (a) the excess of (1) the Fair Market Value of the Common Stock on the date of exercise over (2) the exercise price of such stock appreciation right multiplied by (b) the number of stock appreciation rights exercised will be delivered to the Grantee. Any person exercising a stock appreciation right will make such representations and agreements and furnish such information as the Committee may in its discretion deem necessary or desirable to assure compliance by NBTY, on terms acceptable to NBTY, with the provisions of the Securities Act and any other applicable legal requirements. If a Grantee so requests, shares purchased may be issued in the name of the Grantee and another jointly with the right of survivorship.
2.4.5 Repricing. Except as otherwise permitted by Section 1.6.3, reducing the exercise price of stock appreciation rights issued and outstanding under the Plan, including through amendment, cancellation in exchange for the grant of a substitute Award or repurchase for cash or other consideration (in each case that has the effect of reducing the exercise price), will require approval of the stockholders of NBTY.
2.4.6 Repayment if Conditions Not Met. If the Committee determines that all terms and conditions of the Plan and a Grantee's stock appreciation right Award Agreement in respect of exercised stock appreciation rights were not satisfied, then the Grantee will be obligated to pay the Company immediately upon demand therefor, an amount equal to the excess of the Fair Market Value (determined at the time of exercise) of the shares of Common Stock subject to the exercised stock appreciation rights over the exercise price therefor, without reduction for any amount applied to satisfy withholding tax or other obligations in respect of such stock appreciation rights.
