The provisions of this Section 10 shall survive the Closing. In the event final figures have not been reached on any of the adjustments, prorations or costs, as a result of unavailability of information or otherwise, which are to be adjusted at or prior to Closing pursuant to this Section 10, the parties shall close using adjustments and prorations reasonably estimated by Seller and Purchaser, subject to later readjustment when such final figures have been obtained. If more current information is not available, estimates shall be based upon the prior operating history of the Property, as shown on the most recent bills or payments available. The parties hereto agree that they shall seek to determine the amounts of all prorations and adjustments required hereunder on or before the Closing Date, if possible, and to the extent not then obtainable, as soon as practicable thereafter.
