2. Lapse of Restrictions; Restricted Period. Except as otherwise provided in the Recipient’s Employment Agreement with the Company, the restrictions set forth in Section 1 above shall lapse and a portion of the Restricted Shares shall become unrestricted and freely tradable only as follows: (i) 25% of the Restricted Shares on the day (the “First Measurement Date”) on which the Total Return to the Company’s shareholders for the period beginning      , 200      through the First Measurement Date shall equal at least      % for ten (10) consecutive Business Days; provided, however, the First Measurement Date shall not occur later than      , 20     ;

(ii) 25% of the Restricted Shares on the day (the “Second Measurement Date”) on which the Total Return to the Company’s shareholders for the period beginning      , 200     through the Second Measurement Date shall equal at least      % for ten (10) consecutive Business Days; provided, however, the Second Measurement Date shall not occur later than      , 20     ;

(iii) 25% of the Restricted Shares on the day (the “Third Measurement Date”) on which the Total Return to the Company’s shareholders for the period beginning      , 200     through the Third Measurement Date shall equal at least      % for ten (10) consecutive Business Days; provided, however, the Third Measurement Date shall not occur later than      , 20     ; and

(iv) 25% of the Restricted Shares on the day (the “Fourth Measurement Date”) on which the Total Return to the Company’s shareholders for the period beginning      , 200     through the Fourth Measurement Date shall equal at least      % for ten (l0) consecutive Business Days; provided, however, the Fourth Measurement Date shall not occur later than      , 20     .

In the event the First Measurement Date does not occur on or before      , 20     , Recipient shall forfeit 25% of the Restricted Shares on that date. In the event the Second Measurement Date does not occur on or before      , 20     , Recipient shall forfeit 25% of the Restricted Shares on that date. In the event the Third Measurement Date does not occur on or before      , 20     , Recipient shall forfeit 25% of the Restricted Shares on that date. In the event the Fourth Measurement Date does not occur on or before      , 20     , Recipient shall forfeit 25% of the Restricted Shares on that date.

For purposes of this Agreement, Sections 2(i), 2(ii), 2(iii) and 2(iv) shall be referred to collectively as the “Restricted Period” and “Total Return” shall mean, for the applicable period, the cumulative total return for the Restricted Shares over such period, as measured by (i) the sum of (a) the cumulative amount of dividends paid in respect of the Restricted Shares for such period (assuming that all cash dividends are reinvested in Common Stock as of the payment date for such dividend, based on the closing price of a share of Common Stock on the dividend payment date), and (b) an amount equal to (x) the closing price of a share of Common Stock at the end of such period, minus (y) the closing price of a share of Common Stock on      , 200     ($ ), divided by (ii) the closing price of a share of Common Stock on      , 200     ($ ).

3. Change of Control. The provisions of the Plan applicable to a Change of Control shall apply to the Restricted Stock, and in the event of a Change of Control, the Committee may take such actions as it deems appropriate pursuant to the Plan. Notwithstanding the preceding sentence, if a Change of Control occurs, all of the Restricted Stock shall become immediately unrestricted and freely transferable by the Recipient on the date of the Change of Control.

4. Rights of Stockholder. From and after the Date of Grant and for so long as the Restricted Stock is held by or for the benefit of the Recipient, the Recipient shall have all the rights of a stockholder of the Company with respect to the Restricted Stock, including but not limited to the right to receive dividends and the right to vote such Restricted Stock. Dividends paid on Restricted Stock shall be paid at the dividend payment date for the Common Stock in cash or shares of Common Stock. Stock distributed in connection with a Common Stock split or Common Stock dividend shall be subject to restrictions and a risk of forfeiture to the same extent as the Restricted Stock with respect to which such Common Stock has been distributed.

5. Termination of Employment. Except as otherwise provided in the Recipient’s Employment Agreement with the Company, in the event that Recipient ceases to be employed by the Company for any reason prior to the lapse of the Restricted Period, then the Restricted Stock and any accrued but unpaid dividends that are at that time subject to restrictions set forth herein shall be forfeited to the Company without payment of any consideration by the Company, and neither the Recipient or any of his or her successors, heirs, assigns, or personal representatives shall thereafter have any further rights or interests in such shares of Restricted Stock or certificates.
