Notwithstanding the foregoing, TSR for any Acquired Company (as defined in Section 2.6, below) will be a percentage equal to the difference between (x) the product of (I) 100% plus the “Independent Period TSR” (as defined below) multiplied by (II) 100% plus the “Index Return” (as defined below), minus (y) 100%.

(ii)“Independent Period Value Change” shall mean:

Failed Companies (as defined below), Delisted Companies (as defined below), and Acquired Companies (as defined below) shall remain as Peer Companies, with Failed Companies and Delisted Companies treated in the manner set forth in Section 2.7, and the TSR of any Acquired Companies calculated in accordance with Section 2.4(b), above. “Failed Companies,” shall mean Peer Companies that cease to be publicly traded on a national securities exchange as of the end of the Performance Period as a result of a liquidation commenced under Chapter 7 of the Bankruptcy Code, an assignment of the Company’s assets for the benefit of creditors under applicable state law, or the commencement of a reorganization proceeding under Chapter 11 of the Bankruptcy Code. “Delisted Companies” shall mean Peer Companies that cease to be publicly traded on a national securities exchange at any time during the Performance Period (irrespective of whether they again become publicly traded on a national securities exchange during the Performance Period) as a result of any involuntary failure to meet the listing requirements of such national securities exchange (such as any failure to

meet the minimum common stock price requirement of the exchange), but shall not include any Peer Company that does not meet the listing requirements as a result of any voluntary going private or similar transaction. “Acquired Companies” shall mean Peer Companies that cease to be independently publicly traded on a national securities exchange during the Performance Period as a result of being acquired by another entity (irrespective of whether such acquiring entity is itself publicly traded), or that do not meet the listing requirements of any national securities exchange as a result of any voluntary going private or similar transaction. No companies may be added to the list during the Performance Period.

2.7Award Determination.

(a)General. At the end of the Performance Period, the Peer Companies and the Company shall be ranked together based on their TSR for the Performance Period with the highest TSR being number 1 and the lowest TSR being the number of Peer Companies, including the Company, remaining in the group at the end of the Performance Period, with any and all Failed Companies and Delisted Companies being ranked in last place on the list. Based on the Company's relative TSR rank among the Peer Companies for the Performance Period, Executive will have earned Performance Shares as determined by the Company's rank as follows:

• If the Company is ranked at or above the 90^th percentile of the Peer Companies, including the Company, 200% of the Target Award

• If the Company is ranked at the 50^th percentile or median of the Peer Companies, including the Company, 100% of the Target Award

• If the Company is ranked at the 25^th percentile of the Peer Companies, including the Company, 50% of the Target Award

• If the Company is ranked below the 25^th percentile of the Peer Companies, including the Company, no award will be paid

If the Company is ranked between any of these payout levels, the percentage multiple of the Target Award will be interpolated based on the actual percentile ranking of the Company (rounded to the nearest whole percentile) in relation to the payout levels.

(b)Cap if TSR is Negative. Notwithstanding Section 2.7(a), if the Company's overall TSR is negative for the Performance Period, then the number of Performance Shares earned will be the lesser of (i) one hundred percent (100%) of the Target Award, or (ii) the number of Performance Shares determined in accordance with Section 2.7(a) based on the Company’s relative TSR rank during the Performance Period.

[(a)    Voluntary or Involuntary Termination Prior to Change in Control.

(i)General. Except as provided below, if the Executive voluntarily terminates Continuous Service or if the Company terminates the Executive's Continuous Service during the Performance Period, in either case before a Change in Control, all Performance Shares will be immediately forfeited.

(ii)Termination without Cause; Resignation for Good Reason prior to a Change in Control. Notwithstanding the foregoing, in the event that prior to a Change in Control Executive’s Continuous Service is terminated by the Company without “Cause” or by Executive for “Good Reason” (each as defined in the Company severance plan in which Executive is a participant), then the Executive may be eligible to receive payment of all or a portion of the Performance Shares, if any, that Executive would have received at the end of the Performance Period (based on achievement of the Performance Metric) had Executive not terminated Continuous Service (the “Potential Shares”). Within forty-five days of the date of termination, the Committee shall determine, in its sole and absolute discretion, the portion, if any, of the Potential Shares that Executive shall be entitled to receive, which determination shall be based on such factors as the Committee deems relevant, including, but not limited to, the length of Executive’s Continuous Service during the Performance Period and the circumstances surrounding Executive’s termination. Notwithstanding the foregoing, the Committee shall maintain discretion at any time prior to payment to reduce or eliminate the payment to which Executive is otherwise due based on Executive’s failure to comply with any post-termination restrictive covenants.][ALTERNATIVE 2 – FOR EXECUTIVES IN THE SEVERANCE PLAN.]

Notwithstanding the foregoing, if the triggering event is due to a death that occurs during the first two (2) years of the Performance Period, such pro-rata number of Performance Shares will be based on actual results through the date of death with the Performance Metric calculated with reference to the Average Share Price for the twenty (20) business days prior to the date of death.
