Seller and Buyer agree

that the damages resulting to Seller as a result of such default by Buyer as of the date of this Agreement are difficult or impossible to ascertain and the liquidated damages set forth in the preceding sentence constitute Buyer’s and Seller’s reasonable estimate of such damages.
