The effective time of the Merger is referred to herein as the "Effective Time".

(3) Reflects the acquisition of ROCE-based and TSR-based performance stock units and other performance-based stock awards (collectively, "PSUs") that were deemed to have been earned as of immediately prior to the Effective Time in accordance with the terms of the Merger Agreement.

(5) As a result of the Effective Time, each of the Shares that the reporting person previously reported as beneficially owned under the Company's 401(k) retirement plan was liquidated in exchange for the Per Share Merger Consideration.

(6) Immediately prior to the Effective Time, in accordance with the terms of the Merger Agreement, each of these stock options was converted into the right to receive an amount in cash equal to the positive difference, if any, between the Per Share Merger Consideration and the applicable exercise price, less any applicable tax withholdings.
