<div align="left" style="font-size: 10pt; margin-top: 6pt">     Beginning in 2010, the Company transitioned from its historical practice of granting
certain senior Company employees annual restricted stock awards with time-based vesting provisions
only, to granting these employees the right to receive a designated number of shares of Company
common stock based on the achievement of specific performance criteria over a defined performance
period (the “Performance Stock Awards”). All Performance Stock Awards have been granted under the
Company’s 2003 Incentive Award Plan and are intended to qualify as performance-based compensation
under Section 162(m) of the Internal Revenue Code of 1986, as amended.
</div>
<div align="left" style="font-size: 10pt; margin-top: 6pt">     In February 2010, the Compensation Committee of the Board of Directors of the Company granted
certain senior Company employees Performance Stock Awards based on the Company’s 2010 revenues,
earnings per share and return on invested capital (collectively, the “2010 Performance Stock
Criteria”). Each recipient was eligible to receive between zero and 150% of the target number of
shares of Company common stock subject to the applicable award based on actual performance as
measured against the 2010 Performance Stock Criteria. In February 2011, the Company issued an
aggregate of approximately 37,500 shares of Company common stock to award recipients based on
actual performance. One-third of the issued shares vested on the date of issuance, one-third of the
shares will vest on the first anniversary of the date of issuance and one-third of the shares will
vest on the second anniversary of the date of issuance, as long as the award recipient is employed
by the Company on each such vesting date.
</div>
<div align="left" style="font-size: 10pt; margin-top: 6pt">     In February 2011, the Compensation Committee granted certain senior Company employees
Performance Stock Awards based on the Company’s adjusted relative stockholder return in comparison
to a defined market index over a three-year performance period (the “2011 Performance Stock
Criteria”). Each recipient is eligible to receive between zero and 200% of the target number of
shares of Company common stock subject to the applicable award based on actual performance as
measured against the 2011 Performance Stock Criteria. Performance under the awards will be measured
annually from January 1, 2011 for performance intervals of one, two and three years, with each
performance interval representing one-third of the total potential award. Shares issued following
each annual performance measurement will be immediately vested upon issuance. Award recipients will
be eligible to receive shares issued pursuant to such awards, as long as the award recipient is
employed by the Company on each such issuance date.

million of the Company’s common stock until December 31, 2011, through negotiated or open market
transactions. There is no minimum or maximum number of shares to be repurchased under the program.

<div align="left" style="font-size: 10pt; margin-top: 6pt">     In February 2010, the Company’s Board of Directors authorized the repurchase of up to $100.0
million of the Company’s common stock until December 31, 2010, through negotiated or open market
transactions. There was no minimum or maximum number of shares to be repurchased under the program.
The Company completed the program in December 2010, repurchasing and retiring approximately
2,165,000 shares since the program’s inception at an average price of $46.16 per share, or approximately
$99.9 million in total.
