Explanation of Responses:

( 1 )This price reflects the weighted average sale price for the shares, which were sold in multiple transactions. Upon request of the SEC staff, the issuer, or a security holder of the issuer, the reporting person will provide information regarding the number of shares sold at each separate price. ( 2 )Common stock sold to cover exercise price and income tax withholding related to stock options exercised. ( 3 )Stock settled stock appreciation rights granted under the Issuer's 2005 Incentive Plan. One-third of original grant vested annually, and all rights are currently vested. Rights expire seven years from the grant date, if not earlier terminated or exercised in full, subject to acceleration as provided in said Plan.

Remarks: Mr. Keller retired as an executive officer of the Company in March 2015 and as the Company's CEO in March 2013. As CEO, he was required by the Company's stock ownership guidelines to own Company stock with a value equal to at least six times his annual salary. As a non-employee director, Mr. Keller is required to own Company stock with a value at least equal to three times his annual cash retainer. While Mr. Keller intends to maintain a position in Company stock in excess of the stock ownership guidelines, he plans to sell Company stock in a series of quarterly transactions to diversify his investment portfolio as part of retirement planning.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
