Remarks
Following the transactions contemplated by the Merger Agreement, the reporting person is no longer subject to Section 16 in connection with his transactions in the equity securities of Hornbeck Offshore Services, Inc. (formerly named Helix Energy Solutions Group, Inc.) and therefore will no longer report any such transactions on Form 4 or Form 5. Capitalized terms used herein without definition have the meanings ascribed to them in the Merger Agreement.
