2. Restricted Stock Unit Award. This Agreement specifies the terms of the “Restricted Stock Unit Award” granted to the Participant.

3. Restricted Period. If the Date of Termination does not occur during the Restricted Period with respect to any Installment of the Covered Units, then the Participant shall become vested in such Installment at the end of such Restricted Period. With respect to all Covered Units, the “Restricted Period” for each Installment of Covered Units shall begin on the Grant Date. The Restricted Period with respect to each Installment shall end as described in the

following schedule (but only if the Date of Termination has not occurred before the end of the Restricted Period):

The Restricted Period shall end prior to the date specified in the foregoing schedule to the extent set forth below:

(a)For Installments as to which the Restricted Period has not otherwise ended prior to the Date of Termination, the Restricted Period for such Installments shall end upon the Participant’s Date of Termination, if the Date of Termination occurs by reason of the Participant’s Disability or death or by reason of a Qualifying Termination.

(b)If the Participant’s Date of Termination occurs because of Retirement, then for Installments as to which the Restricted Period has not otherwise ended prior to the Date of Termination, the Participant shall be vested on the Date of Termination (and the Restricted Period shall end) with respect to the Installment (if any) that would vest on or after the Date of Termination, determined as though the Participant had remained employed through such vesting date(s), but subject to paragraph 17(j) (relating to the definition of Retirement); provided, however, the number of Covered Units that shall be delivered with respect to each Installment on or after the Date of Termination due to Retirement, shall be further multiplied by the Retirement Percentage (with such percentage converted to a number by dividing such percentage by 100) and, if such Retirement Percentage is less than one hundred percent (100%), any Covered Units that do not remain eligible to become vested pursuant to this sentence shall be immediately forfeited on the Date of Termination.

4. Transfer of Shares and Forfeiture of Units. On the Delivery Date, the Participant shall receive one share of Stock for each Unit in which the Participant is then vested, and such shares shall be free of restrictions otherwise imposed by this Agreement, subject to the terms of this Agreement applicable after such Delivery Date (including, without limitation, paragraph 9) and the Plan. As of the date of distribution of Shares with respect to any Units, such Units shall be canceled. If the Restricted Period with respect to any Installments does not end on or before the Participant’s Date of Termination, then as of the Participant’s Date of Termination, the Participant shall forfeit such Installments. However, the Committee, in its sole discretion, may accelerate the end of the Restricted Period or provide for the vesting of the Covered Units under

circumstances that such vesting would not otherwise occur in its sole discretion, based on such factors as the Committee deems appropriate.

5. Change in Control. In the event of a Change in Control, the Company, or the entity that is the surviving entity or successor to the Company following such transaction, may elect to (a) to continue this Restricted Stock Unit Award subject to the terms of this Agreement and the Plan and subject to such adjustments, if any, by the Committee as permitted by Section 5.2(f) of the Plan; or (b), if the Change in Control also satisfies the definition of “change in control event” as set forth in Treas. Reg. 1.409A-3(i)(5), to terminate this Restricted Stock Unit Award and distribute shares of Stock consistent with Treas. Reg. 1.409A-3(j)(4)(ix)(B). In the event that the Company or its successor chooses to terminate this award and make a distribution of shares of Stock as provided in clause (b) of the previous sentence (in which case the Change in Control is a Vesting Change in Control), the Participant shall be entitled to receive one share of Stock for each Unit which has not previously been forfeited and the date of the Vesting Change in Control shall be treated as the Delivery Date for purposes of this Agreement. The shares of Stock received by a Participant pursuant to this Section 5 shall be free of restrictions otherwise imposed by this Agreement and the Plan; provided, however, that the shares of Stock shall remain subject to the terms of this Agreement expressly applicable after the Delivery Date (including, without limitation, Section 10).

6. Withholding. All deliveries and distributions under this Agreement are subject to withholding of all applicable taxes. At the election of the Participant, and subject to such rules and limitations as may be established by the Committee from time to time, such withholding obligations may be satisfied through the surrender of shares of Stock which the Participant already owns, or to which the Participant is otherwise entitled under the Plan; provided, however, that such shares of Stock may be used to satisfy not more than the maximum individual tax rate for the Participant in applicable jurisdiction for such Participant (based on the applicable rates of the relevant tax authorities (for example, federal, state, and local), including the Participant’s share of payroll or similar taxes, as provided in tax law, regulations, or the authority’s administrative practices, not to exceed the highest statutory rate in that jurisdiction, even if that rate exceeds the highest rate that may be applicable to the specific Participant).

7. Transferability. Except as otherwise provided by the Committee, the Restricted Stock Unit Award may not be sold, assigned, transferred, pledged or otherwise encumbered during the Restricted Period.

8. Dividends. To the extent that the Covered Units have not otherwise been forfeited or cancelled prior to the Delivery Date, the Participant will be paid a cash payment on the Delivery Date equal to the number of shares of Stock delivered pursuant to Sections 4 or 5, multiplied by the total amount of dividend payments made in relation to one share of Stock with respect to record dates occurring during the period between the Grant Date and the Delivery Date.

9. Voting. The Participant shall not be a shareholder of record with respect to the Units and shall have no voting rights with respect to the Units during the Restricted Period or prior to the Delivery Date.

10. Cancellation and Rescission of Restricted Stock Unit Award.

(a)The Committee may cancel, rescind, suspend, withhold, or otherwise limit or restrict the Restricted Stock Unit Award at any time if the Participant engages in any Detrimental Activity or if the Participant engages in any conduct that constitutes Cause or, in the case of a Participant whose Date of Termination has occurred due to Retirement, if the Participant engages in any Post-Retirement Activity.

(b)At the Delivery Date with respect to an Installment and prior to the transfer of the shares of Stock to the Participant, the Participant shall certify, to the extent required by the Committee, in a manner acceptable to the Committee, that the Participant is not engaging and has not engaged in any Detrimental Activity and, in the case of a Participant whose Date of Termination has occurred due to Retirement, that the Participant is not engaging and has not engaged in any Post-Retirement Activity. In the event a Participant has engaged in any Detrimental Activity or, if applicable, any Post-Retirement Activity, prior to or during the twelve months after the Delivery Date with respect to such Installment of Covered Units, the right to delivery of shares with respect to such Installment may be rescinded by the Committee within two years thereafter. In the event of any such rescission, the Participant shall pay to the Company the amount of any gain realized as a result of the prior delivery of shares applicable to the rescinded Installment(s), in such manner and on such terms and conditions as may be required by the Company, and the Company shall be entitled to set-off against the amount of any such gain any amount owed to the Participant by the Company and/or Subsidiary.

11. Heirs and Successors.

The “Designated Beneficiary” shall be the beneficiary or beneficiaries designated by the Participant in a writing filed with the Committee in such form and at such time as the Committee shall require. If a deceased Participant fails to designate a beneficiary, or if the Designated Beneficiary does not survive the Participant, any rights that would have been exercisable by the Participant and any benefits distributable to the Participant shall be distributed to the legal representative on behalf of the estate of the Participant. If a deceased Participant designates a beneficiary and the Designated Beneficiary survives the Participant but dies before the complete distribution of benefits to the Designated Beneficiary under this Agreement, then any benefits distributable to the Designated Beneficiary shall be distributed to the legal representative on behalf of the estate of the Designated Beneficiary. Any benefits deliverable following the death of the Participant to the Designated Beneficiary or the legal representative on behalf of the estate will be made as soon as administratively possible following the date that the Company determines to whom such benefits should be made pursuant to this Section 11 and in any event within the period required pursuant to Section 409A of the Code.
