To date, the Company has repurchased $411,256,895 in Common Stock under the Company’s Share Repurchase Program, which is inclusive of the share repurchase described above. The timing and amount of future share repurchases under the Company’s Share Repurchase Program, including any additional repurchases from REH, will depend on market conditions and corporate, tax, regulatory and other relevant considerations. The Share Repurchase Program may be discontinued at any time by the Board of Directors of the Company.

The foregoing description of the Stock Purchase Agreement does not purport to be complete and is qualified in its entirety by reference to the Stock Purchase Agreement, a copy of which is filed herewith as Exhibit 10.1 and is incorporated by reference herein.
