The Option may be exercised in whole (but not in part) at any time after the date hereof and on or prior to the first anniversary of the date hereof (such first anniversary, the "Option Expiration Date") in the event that (i) a Specified Event (as defined in Section 1(b) below) shall have occurred on or prior to the Option Expiration Date and (ii) the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the "HSR Act") with respect to the exercise of the Option shall have expired or been terminated.

(c) In the event that Sub wishes to exercise the Option, Sub may do so by giving written notice (the date of such notice being herein called the "Notice Date") to each of the Stockholders specifying that all the Subject Shares are to be purchased and specifying the place, time and date (not earlier than two trading days, nor later than 10 trading days, from the Notice Date) for the closing of the purchase by Sub pursuant to such exercise. In the event that any share of Common Stock is accepted for payment, and paid for, by Sub pursuant to the Offer, Sub shall be obligated to exercise the Option no later than two trading days following the date of such payment and close the purchase of and pay for such Subject Shares within two trading days following the date of such exercise. A "trading day" shall mean any date on which the New York Stock Exchange shall be open for business. 2.
