Notwithstanding this provision, neither Principal nor Holder agrees to indemnify Purchaser against any third-party claims related to the Nelton Court Project;

(iv) the Holder and the Principal shall assume and resolve, at their sole cost and expense, all other claims or liabilities arising out of or related to the KBE Agreement or the Nelton Court Project; provided that the Holder and the Principal may at their sole discretion use the Retainage to offset such claims or liabilities; and
