Subject to satisfaction of the relevant conditions for Closing, the Buyer shall reimburse direct or cause the Company to reimburse to the Seller upon the Closing Date the reasonable costs of the supervision of construction of the Rigs incurred by the Company or Seller in the period between the date of this Agreement and Closing Date.

Furthermore, the Seller shall ensure that neither the Company nor any Affiliate shall negotiate or enter into any agreement or understanding with any third party for the sale or disposal of the Shares or the Rigs or its rights and interests under the Construction Contracts or Vendor Agreements, or enter into any agreement or understanding which is contrary to the Buyer’s interests in relation to the transactions contemplated under this Agreement or the Buyer’s interest in the Drillship Option, in the period from the date hereof until the Cancellation Date.

The Seller acknowledges and agrees that the Buyer may disclose such information, including terms and conditions, from or relating to this Agreement and the Material Contracts as it sees fit in connection with seeking Stockholder Approval and financing.
