The Seller further agrees, subject to the Buyer’s payment of the Deposit, to make the captain, chief engineer, ETO, and drilling superintendent of the Unit available for a period of five (5) consecutive calendar days to perform a walk through of the Unit with the Buyer’s project team and provide responses to Buyer’s reasonable inquiries regarding the status of the Unit.

(b)   The Seller agrees that, solely for the purpose of determining whether the Buyer shall have the obligation to close, the Unit is to be in, at the Closing Date, the same overall condition, irrespective of any class conditions or recommendations, as at the time of the Inspection, fair wear and tear excepted and subject to De Minimis Losses and the provisions of Article 9.2 (“Inspection Condition”); PROVIDED THAT if the Buyer fails to notify the Seller prior to the Closing Date that the Unit is not in such Inspection Condition, the Unit will be conclusively presumed to be in such Inspection Condition at the Closing Date for all purposes of this Agreement and the Buyer shall have no further rights hereunder in connection with the actual condition or composition of the Unit.  The Buyer shall provide written notice to the Seller prior to the Closing in the event that the Buyer believes that the Unit is not in the Inspection Condition, and/or that the composition of the Unit is not as required by this Agreement. Any such notice shall specifically list the deficiencies claimed by the Buyer and must be subject to reasonable verification by the Seller (with any actual deficiencies referred to herein as “Deficiencies”). In the event the Buyer notifies the Seller of Deficiencies, such Deficiencies shall be subject to the provisions of Article 9.2.  Under no circumstances shall the Seller be liable or obligated after the Closing Date to the Buyer with regard to the physical condition or composition of the Unit, the Onshore Unit Equipment or the Onboard Unit Equipment unless otherwise stated in Article 4.3 above, and the Buyer hereby agrees that all rights it may otherwise have in connection therewith shall be automatically and irrevocably waived from and after Closing without any further act of the Buyer or the Seller.
