2. Represents the exercise price of the Stock Option.

3. Of the amount shown, 112,900 shares are held in the qualified pension plan account of the reporting person, which number was incorrectly reported on previous filings by 144 shares on a stock split-adjusted basis due to an administrative error that occurred in February 2009.

These total ownership figures are also corrected from previous filings to reflect gifts of shares made by the reporting person between April 2012 and November 2013, the details of which are reported on a Form 5 for the fiscal year ended Decenber 31, 2014 filed on the same date as this amendment.

4. Represents 20,071 shares withheld to cover the exercise price of the Stock Option and 30,868 shares withheld to satisfy minimum statutory tax withholding obligations upon exercise of the Stock Option.

5. Fair market value of the shares, as of the market closing price on August 21, 2014, which is the day prior to the exercise of the Stock Option.

6. The previous filing incorrectly omitted shares indirectly held by the reporting person.

7. The previous filing inadvertently placed the amount of shares exercised under the "Acquired" column.

8. Represents the date to which vesting of the Stock Option was accelerated, as approved by the Company's Board of Directors.

9. Represents the amount of underlying shares subject to the full exercise of the Stock Option.
