( 1 )On May 4, 2017, pursuant to the agreement and plan of merger dated December 9, 2016 (the "Merger Agreement"), among the Issuer, Sibanye Gold Limited, a public company organized under the laws of South Africa ("Sibanye"), Thor US HoldCo Inc., a Delaware corporation and an indirect wholly owned subsidiary of Sibanye ("US Holdco"), and Thor Mergco Inc., a Delaware corporation and a direct wholly owned subsidiary of US Holdco ("Merger Sub") Merger Sub was merged with and into the Issuer (the "Merger"), with the Issuer as the surviving corporation. Upon closing of the Merger, each of the Issuer's shares of Common Stock, par value $0.01 per share (the "Shares"), not owned directly or indirectly by the Issuer, Sibanye, or any of their direct or indirect subsidiaries, was converted into the right to receive $18.00 in cash (the "Merger Consideration"). The amount of the Reporting Person's common stock listed in Table I includes 1,753 shares maintained in a 409A account. ( 2 )Represents Shares underlying Deferred Share Units ("DSUs") outstanding immediately prior to the closing of the Merger. Pursuant to the Merger Agreement, any vesting conditions applicable to each outstanding DSU automatically accelerated in full, each such DSU was canceled, and the Reporting Person was entitled to receive (without interest) an amount in cash equal to the product of (x) the total number of Shares subject to the DSU, multiplied by (y) the Merger Consideration.
