In addition to the foregoing, Purchaser will provide Seller copies of any official correspondence from governmental authorities relating to the issuance of requested Permits and governmental approvals for the Restart Production.

If Purchaser (or its Affiliate) has timely applied for and is diligently pursuing such consents and approvals in accordance with the terms of this Agreement, but a consent or approval is withheld, delayed or conditioned by the applicable governmental authority, Purchaser shall promptly notify Seller of the circumstances of same so that the Parties may, subject to the terms of this Agreement and applicable Laws, consider potential further actions in respect thereof.”

Without limitation to Section 11.12, during the period extending from the Closing until such time as (i) such bonds, guarantees or other financial security are posted by Purchaser (or its Affiliate on its behalf) with and accepted by the applicable governmental authority, (ii) any related security provided by Seller has been released, and (iii) all such approvals by the BOEM or other governmental authorities have been obtained, Purchaser shall name Seller as an additional insured on Purchaser’s insurance policies.” f.
