     WHEREAS, Buyer and Seller entered into that certain Asset Purchase Agreement, dated effective as of December 14, 2005 (the “Agreement”);

     WHEREAS, Buyer and Seller desire to amend the Agreement as set forth below; and

     WHEREAS, all capitalized terms used but not otherwise defined shall have the meaning given such terms in the Asset Purchase Agreement;

     NOW, THEREFORE, in consideration of the premises, the respective representations, warranties, covenants and agreements contained herein, and other good and valuable consideration, the legal sufficiency of which is hereby acknowledged, the parties hereto agree as follows:

All references to Burris Run Company and/or Red Clay Minerals in the Agreement and in the exhibits and schedules thereto are hereby deemed deleted ab initio. The parties understand that such deletions mean that, among other things, Burris Run Company and Red Clay Minerals are no longer deemed to have made any representations, warranties, indemnities or covenants under the Agreement.

     2. In Section 1.2(a) of the Agreement, the phrase “EIGHTY SIX MILLION SIX HUNDRED SEVENTY THOUSAND AND 00/100 DOLLARS ($86,670,000.00)” is hereby deleted and replaced with the following: “EIGHTY SIX MILLION ONE HUNDRED ELEVEN THOUSAND EIGHT HUNDRED NINE AND 00/100 DOLLARS ($86,111,809.00)”.

     3. In the first (1^st) sentence of Section 2.5(d) of the Agreement, the phrase “Except for Buyer’s remedies under this Agreement for a breach of Seller’s representation contained in Section 3.19,” is hereby deleted.

     8. This Amendment may be executed in counterparts, each of which will constitute an original, but all of which, when taken together, will constitute but one agreement. If the parties sign separate counterparts of this Amendment, then a signature page signed by one party and a signature page signed by another party may be placed together in a complete counterpart of this Amendment and such two signature pages, together with the remainder of such complete counterpart of this Amendment, will constitute one complete and fully-executed original of this Amendment. Executed copies hereof may be delivered by telecopier or electronic mail and upon receipt will be deemed originals and binding upon the parties hereto, regardless of whether originals are delivered thereafter.

     IN WITNESS WHEREOF, the parties hereto have duly executed this Amendment as of the date first above written.
