Explanation of Responses:

1. As previously reported, on February 25, 2015, the reporting person received a grant of 38,352 time-based restricted stock units that vest in one-third increments on each of the first, second and third anniversaries of the date of grant. The first anniversary occurred on February 25, 2016, resulting in the vesting and settlement of 12,784 shares of common stock. The second vesting date occurred on February 24, 2017 (the business day prior to the anniversary date which fell on a weekend), resulting in the vesting and settlement of 12,784 shares of common stock. The third vesting date occurred on February 23, 2018 (the business day prior to the anniversary date which fell on a weekend), resulting in the vesting and settlement of 12,784 shares of common stock, as shown in Table I.

2. Restricted stock units convert into common stock on a one-for-one basis.

3. Shares withheld for payment of taxes upon vesting of restricted stock units in accordance with Rule 16b-3.

4. On 2/25/15, the reporting person received a target grant of 38,352 performance-based RSUs that were subject to the Company's attainment of a specified one-year performance metric for the year then-ending 12/31/15. The actual number of stock units that could vest ranged from 0% to 200% of the target unit amount. The performance metric was exceeded & 164.7% of the target grant was awarded; therefore, these RSUs vest in 1/3 increments on each of the 1st, 2nd & 3rd anniversaries of the date of grant. The 1st anniversary occurred 2/25/16, resulting in the vesting & settlement of 21,056 shares of common stock. The 2nd vesting date occurred 2/24/17 (the business day prior to the anniversary date which fell on a weekend), resulting in the vesting & settlement of 21,056 shares of common stock. The 3rd vesting date occurred 2/23/18 (the business day prior to the anniversary date which fell on a weekend), resulting in the vesting & settlement of 21,054 shares of common stock as shown in Table I.

5. Both time-based restricted stock units and performance-based restricted stock units are settled in shares of the Company's common stock upon vesting.
