              Title
                    Commitment.  Seller shall make arrangements with Buffalo Land Title, LLC, , 7306 South Lewis Avenue, Tulsa, Oklahoma 74136 (the “Closing





                    Agent” or the “Title Company”) to furnish Buyer, within ten (10) days after the Effective Date, with commitment for the
                  issuance of an ALTA extended coverage owner’s policy of title insurance on the Property, issued by a title insurance company selected by, or acceptable to, Buyer in the amount of the Purchase Price, and describing the state of title to
                  such Property with copies of instruments referenced in any requirements or exceptions to title.

            


    

    
      
        
          


      

      
      	
              b.

            	
              UCC Searches. 





                  Seller shall, within ten (10) days after the Effective Date, obtain and deliver to Buyer Uniform Commercial Code Search Certificates naming Seller, as Debtor, from the Missouri Secretary of State - UCC Division (the “UCC Certificate”).

            


    

    
      	
              c.

            	
              Title
                    Examination.  Buyer shall have a period of ten (10) days from date on which it has received the Title Commitment and the UCC Certificate (collectively, referred to as the “Title Evidence”) in which to have such Title Evidence examined and to furnish Seller written notice of any objections to the requirements or title exceptions set forth in the Title
                  Commitment (“Buyer’s Title Objections Notice”).

            


    

    
      	
              i.

            	
              If Buyer fails to provide its required Title Objections Notice with respect to any title exception within the
                  time allowed, then Buyer shall be deemed to have waived objection to such title exception.  Seller, upon receipt of Buyer’s Title Objection Notice, shall have ten (10) days, or such additional time as may be agreed to in writing by Seller
                  and Buyer, in which to attempt to cure and satisfy all unwaived objections and deliver written notice to Buyer (“Seller’s Title Objections
                    Response”) of Seller’s election either (i) to take such action as shall be required to cause the Title Company to remove Buyer’s objectionable items prior to the Closing or (ii) to refrain from removing one or more of such Buyer
                  objectionable items.  Seller’s failure to deliver Seller’s Title Objections Response within the time allowed shall constitute an election by Seller not to cure Buyer’s objectionable items.

            


    

    
      	
              ii.

            	
              If Seller notifies Buyer that it elects to do anything other than unconditionally cure all
                  of Buyer’s title objections, then, Buyer shall have the right either (i) to agree to accept the Property subject to any of Buyer’s objectionable items that will not be cured by Seller or (ii) to terminate this Agreement.
