If the purchases for all Participants would otherwise cause the aggregate number of Common Shares to be sold under the Plan to exceed the number specified in Section 10.03, each Participant shall be allocated a pro rata portion of the Common Shares to be sold.

Section 4.02  Purchase Price . The purchase price for any Purchase Period shall be the lesser of (a) 85% of the Fair Market Value of the Common Shares on the first business day of that Purchase Period or (b) 85% of the Fair Market Value of the Common Shares on the last business day of that Purchase Period, in each case rounded up to the next higher full cent.

ARTICLE V. EXERCISE OF RIGHT

Section 5.01  Purchase of Shares . On the last business day of a Purchase Period, the entire credit balance in each Participant's Share Purchase Account will be used to purchase the largest number of whole Common Shares purchasable with such amount (subject to the limitations of Section 4.01), unless the Participant has filed with the Company, in advance of that date and subject to such terms and conditions as the Committee in its sole discretion may impose, a form provided by the Company which requests the distribution of the entire credit balance in cash.

Section 5.02  Cash Distributions . Any amount remaining in a Participant's Share Purchase Account after the last business day of a Purchase Period will be paid to the Participant in cash in a timely fashion after the end of that Purchase Period.

ARTICLE VI. WITHDRAWAL FROM PLAN; SALE OF SHARES

Section 6.01  Voluntary Withdrawal . A Participant may, in accordance with such terms and conditions as the Committee in its sole discretion may impose, withdraw from the Plan and cease making payroll deductions by filing with the Company a form provided for this purpose.

Section 6.02  Death . Subject to such terms and conditions as the Committee in its sole discretion may impose, upon the death of a Participant, no further amounts shall be credited to the Participant's Share Purchase Account. Thereafter, on the last business day of the Purchase Period during which such Participant's death occurred and in accordance with Section 5.01, the entire credit balance in such Participant's Share Purchase Account will be used to purchase Common Shares, unless such Participant's estate has filed with the Company, in advance of that day and subject to such terms and conditions as the Committee in its sole discretion may impose, a form provided by the Company which elects to have the entire credit balance in such Participant's Shares Account distributed in cash within 30 days after the end of that Purchase Period or at such earlier time as the Committee in its sole discretion may decide. Each Participant, however, may designate one or more beneficiaries who, upon death, are to receive the Common Shares or the amount that otherwise would have been distributed or paid to the Participant's estate and may change or revoke any such designation from time to time. No such designation, change or revocation will be effective unless made by the Participant in writing and filed with the Company during the Participant's lifetime. Unless the Participant has otherwise specified the beneficiary designation, the beneficiary or beneficiaries so designated will become fixed as of the date of the death of the Participant so that, if a beneficiary survives the Participant but dies before the receipt of the payment due such beneficiary, the payment will be made to such beneficiary's estate.

Section 6.03  Termination of Employment . Subject to such terms and conditions as the Committee in its sole discretion may impose, upon a Participant's normal or early retirement with the consent of the Company under any pension or retirement plan of the Company or Participating Affiliate, no further amounts shall be credited to the Participant's Share Purchase Account. Thereafter, on the last business day of the Purchase Period during which such Participant's approved retirement occurred and in accordance with Section 5.01, the entire credit balance in such Participant's Share Purchase Account will be used to purchase Common Shares, unless such Participant has filed with the Company, in advance of that day and subject to such terms and conditions as the Committee in its sole discretion may impose, a form provided by the Company which elects to receive the entire credit balance in such Participant's Share Purchase Account in cash within 30 days after the end of that Purchase Period, provided that such Participant shall have no right to purchase Common Shares in the event that the last day of such a Purchase Period occurs more than three months following the termination of such Participant's employment with the Company by reason of such an approved retirement. In the event of any other termination of employment (other than death) with the Company or a Participating Affiliate, participation in the Plan will cease on the date the Participant ceases to be a Full-Time Employee for any reason. In such event, the entire credit balance in such Participant's Share Purchase Account will be paid to the Participant in cash within 30 days. For purposes of this Section 6.03, a transfer of employment to any Affiliate, or a leave of absence which has been approved by the Committee, will not be deemed a termination of employment as a Full-Time Employee.
