(c) Upon the termination of a Purchase Right, all amounts held in the Participant’s Account shall be refunded to the Participant.

4.2 Exercise of Purchase Rights.

(a) Unless previously terminated, Purchase Rights will be exercised automatically on the last day of the Purchase Right Period.

(i) Deposited at the beginning of a Purchase Right Period; and/or

(ii) Accumulated through payroll deductions made during the Purchase Right Period.

(c) If the balance of the Participant’s Account on the date of purchase exceeds the purchase price of the whole number of shares to be acquired, the surplus shall be applied to the next Purchase Right Period, unless the Participant elects to receive a refund by submitting a form prescribed by the Committee to the People Services Department of the Company.

(d) Following the end of each Purchase Right Period, the number of shares of Common Stock purchased by each Participant shall be deposited into an account established in the Participant’s name at the Plan Broker, or otherwise transferred to or for the account of the Participant.

(e) A Participant shall be free to make a disposition (as that term is defined in Code Section 424(c)) of the shares in the Participant’s account at the Plan Broker at any time, whether by sale, exchange, gift, or other transfer of legal title, but in the absence of such a disposition of the shares, the shares must remain in the Participant’s account at the Plan Broker until the holding period set forth in Code Section 423(a) has been satisfied. With respect to shares for which the holding period set forth in Code Section 423(a) has been satisfied, the Participant may move such shares to another brokerage account of the Participant’s choice or request that such shares otherwise be transferred to or for the account of the Participant. (As of the effective date of this 2007 Amendment and Restatement of the Plan, the holding period set forth in Code Section 423(a) is the longer of two (2) years after the first day of the Purchase Right Period and one (1) year after the last day of the Purchase Right Period during which the shares were purchased by the Participant.)

(b) The Purchase Right Period in which a Termination Event occurs shall terminate and all Purchase Rights shall be automatically exercised immediately preceding the Termination Event. In the case of a Termination Event described in Section 4.3(a)(i) or 4.3(a)(ii) above, for purposes of determining the amount under Section 3.4(b), the Fair Market Value of the Common Stock on the last day of the Purchase Right Period shall be deemed to be equal to the per share consideration received in the transaction by the holders of the Common Stock.
