(iv)The Participant does not accept and does not intend to accept employment with a competitor of any business unit of the Corporation or any of its Subsidiaries and will so certify if required by the Committee or a delegate thereof; provided that the Committee or a delegate thereof may, in its sole discretion, waive such prohibitions.

3.    Dividend Equivalents. During the period of time between the Grant Date and the earlier of the date the Restricted Units vest or are forfeited, the Participant shall be entitled to receive dividend equivalent payments, in cash, from the Corporation on the Restricted Units. Payment of a dividend equivalent, if any, shall be made on or after, but not later than thirty (30) days after, such times as an ordinary quarterly cash dividend is paid on the Common Stock of the Corporation.

4.    Issuance of Shares. During the period of time between the Grant Date and the earlier of the date on which the Restricted Units vest or are forfeited, the Restricted Units will be evidenced by a credit to a bookkeeping account evidencing the unfunded and unsecured right of the Participant to receive shares of Common Stock, subject to the terms and conditions applicable to the Restricted Units under the Plan and this Award Agreement. Upon the vesting of all or a portion of the Participant’s Restricted Units pursuant to Section 2 of this Award Agreement, a number of shares of Common Stock equal to the number of vested Restricted Units shall be registered in the name of the Participant. Such registration shall occur on or after, but not later than thirty (30) days after, the date on which the Restricted Units vest. No fractional shares will be issued and any rights to fractional shares of Common Stock will be forfeited without compensation for such fractional shares.

    5.    Forfeiture or Repayment Resulting from Forfeiture Event.

Any Forfeiture Amount shall be paid by the Participant within sixty (60) days of receipt from the Corporation of written notice requiring payment of such Forfeiture Amount.

(c)     This Section 5 shall apply notwithstanding any provision of this Award Agreement to the contrary and is meant to provide the Corporation with rights in addition to any other remedy which may exist in law or in equity. This Section 5 shall not apply to the Participant following the effective time of a Change in Control.

Pursuant to Section 10 of the Plan, the Corporation or its designated representative (which may be a Subsidiary) shall have the right to withhold applicable taxes from the shares of Common Stock otherwise deliverable to the Participant due to the vesting of Restricted Units pursuant to Section 2 of this Award Agreement, or from other compensation payable to the Participant, at the time of the vesting of the Restricted Units and issuance of shares of Common Stock or such other time as may be required under applicable law, to sell or permit the sale of shares of Common Stock to pay such applicable taxes, or to take such other action as may be necessary in the opinion of the Corporation to satisfy all obligations for withholding.

7.    Nonassignability. Upon the Participant’s death, the Restricted Units shall vest and be issued in accordance with Sections 2(b) and 4 above, and shares of Common Stock shall be transferred to the Participant’s designated beneficiary on file with the Plan’s third party stock plan administrator or, if none, to the Participant’s estate. Otherwise, the Participant may not sell, transfer, assign, pledge or otherwise encumber any portion of the Restricted Units, and any attempt to sell, transfer, assign, pledge or encumber any portion of the Restricted Units shall have no effect.

8.    No Employment Guaranteed. Nothing in this Award Agreement shall give the Participant any rights to (or impose any obligations for) continued Employment by the Corporation or any Subsidiary or successor, nor shall it give such entities any rights (or impose any obligations) with respect to continued performance of duties by the Participant.

9.    Nature of the Grant. In accepting this Award Agreement, the Participant acknowledges that:

(a)    the grant of Restricted Units is voluntary and occasional and does not create any contractual or other right to receive future awards of Restricted Units, or benefits in lieu of Restricted Units even if Restricted Units have been awarded repeatedly in the past; and

(b)    Restricted Units are not part of normal or expected compensation or salary for any purpose, including, but not limited to, calculation of any severance, resignation, termination, redundancy, end of service payments, bonuses, long-service awards, pension or retirement benefits or similar payments and in no event should be considered as compensation for, or relating in any way to, past services for the Corporation or its Subsidiaries.
