Vesting

Vesting/Lapse of Forfeiture Restrictions

(a) As soon as administratively practicable after the last day of the Performance Period, the Committee shall determine the EBIT, Ending Shareholders' Equity and Return on Equity for the Performance Period. The Committee's determinations pursuant to the preceding sentence shall be certified by the Committee in writing and delivered to the Secretary of the Company. For purposes of the preceding sentence, approved minutes of the Committee meeting in which the certification is made shall be treated as a written certification. At the time of such certification and based on the Return on Equity for the Performance Period, the Restricted Performance Shares shall Vest in accordance with the following schedule (rounded to the nearest whole share):

Return on Equity for the Performance Period	Percentage of Restricted Performance Shares Vesting
At or above the Full Vesting XXX Percentage	100%
Above the Threshold Vesting XXX Percentage but less than the Full Vesting XXX Percentage	Interpolated percentage between 20% and 100%
At the Threshold Vesting XXX Percentage	20%
Below the Threshold Vesting XXX Percentage	0%

The interpolated percentage referred to in the schedule above shall be determined by increasing the 20% Vesting percentage for a Return on Equity equal to the Threshold Vesting XXX Percentage by the Incremental Percentage for each one-tenth of one percent (0.1%) by which the Return on Equity exceeds the Threshold Vesting XXX Percentage. To illustrate, if, for the Performance Period, the Full Vesting XXX Percentage is 18.0%, the Threshold Vesting XXX Percentage is 12.0%, and the Return on Equity is 15.6%, then the Incremental Percentage is 1⅓% (80% divided by (10 multiplied by (18.0% minus 12.0%))). Since the Return on Equity exceeds the Threshold Vesting XXX Percentage in this example by 3.6% (or 36 one-tenth of one percent increments), the Vesting percentage shall be 68% (20% plus (1⅓% multiplied by 36)).

(b) Notwithstanding any provision of Section 4.1(a) to the contrary and except as provided in Section 4.2 and Section 4.3, no Restricted Performance Shares shall Vest if Participant's Service is terminated prior to the last day of the Performance Period for reasons other than death

Acceleration of Vesting

. In the event of a Change in Control prior to the last day of a Performance Period and while Participant is in the Service of the Company or a Subsidiary (or in the event of a termination of Participant's Service for any reason whatsoever prior to the last day of a Performance Period and upon the date upon which a Change in Control occurs), all of the Restricted Performance Shares with respect to such Performance Period shall Vest as of the effective date of such Change in Control.
Effect of Termination of Service on Vesting.

Delivery of Restricted Performance Shares

Delivery of Restricted Performance Shares

. As soon as practicable after the Restricted Performance Shares become Vested, and subject to the tax withholding referred to in Section 7.4, the Company shall deliver to Participant stock certificates issued in Participant's name for the number of such Vested Restricted Performance Shares.
Status of Restricted Performance Shares and Restrictions
1. Status of Restricted Performance Shares
  
  . With respect to the status of the Restricted Performance Shares, at the time of execution of this Agreement Participant understands and agrees to all of the following:
2. Certificates and Shareholder Rights
  
  . Restricted Performance Shares shall not constitute issued and outstanding shares of Common Shares until issued and delivered in accordance with this Agreement and the Plan. Prior to the time the Restricted Performance Shares are issued and delivered, Participant will not have the right to vote any Restricted Performance Shares, to receive or retain any dividends or distributions paid or distributed on issued and outstanding shares of Common Shares or to exercise any other rights, powers and privileges of a shareholder with respect to any Restricted Performance Shares. In accordance with the provisions of Article V, the Company shall deliver to Participant stock certificates issued in Participant's name for the number of Restricted Performance Shares that have become Vested.
3. Corporate Acts
. The existence of the Restricted Performance Share awards shall not affect in any way the right or power of the Supervisory Board or the shareholders of the Company to make or authorize any adjustment, recapitalization, reorganization or other change in the Company's capital structure or its business, any merger or consolidation of the Company, any issue of debt or equity securities, the dissolution or liquidation of the Company or any sale, lease, exchange or other disposition of all or any part of its assets or business or any other corporate act or proceeding; provided, however, that in the event of a stock split, stock dividend paid in shares, or similar reorganization affecting all or substantially all of the Company's shares, the Restricted Shares shall similarly and automatically be split or reorganized without further action or decision by the Company or the Committee. The prohibitions of Section 3.1 shall not apply to the transfer of Restricted Share awards pursuant to a plan of reorganization of the Company, but the stock, securities or other property received in exchange therefor shall also become subject to the Forfeiture Restrictions and provisions governing the lapsing of such Forfeiture Restrictions applicable to the original Restricted Performance Shares for all purposes of this Agreement.
Miscellaneous
1. Service Relationship
  
  . For purposes of this Agreement, any question as to whether and when there has been a termination of Participant's Service, and the cause of such termination, shall be determined by the Committee, and its determination will be final.

The Company shall not be required (i) to transfer on its books any shares that will have been transferred in violation of this Agreement or (ii) to treat as owner of such shares, to accord the right to vote as such owner, or to pay dividends to any transferee to whom such shares will have been so transferred.
4. Withholding of Tax
  
  . To the extent that the receipt of Restricted Performance Shares or the lapse of any Forfeiture Restriction results in compensation income to Participant for federal or state income tax purposes, Participant shall deliver to the Company at the time of such event such amount of money or Common Shares as the Company may require to meet all obligations under applicable tax laws or regulations, and, if Participant fails to do so, the Company is authorized to withhold or cause to be withheld from any cash or Common Shares remuneration then or thereafter payable to Participant any tax required to be withheld by reason of such resulting compensation income.
5. No Employment Rights Conferred
  
  . No provision of this Agreement shall confer any right upon Participant to continued employment with the Company or any Subsidiary.

  . No provision of this Agreement shall be construed to give Participant or any other person any interest in any fund or in any specified asset or assets of the Company or a Subsidiary.
