Material Terms of Trading Arrangement

Securities Trading Plans of Executive Officers and Directors

Rule 10b5-1 under the Exchange Act provides an affirmative defense that enables pre-arranged transactions in securities in a manner that avoids concerns about initiating transactions at a future date while possibly in possession of material nonpublic information. Our Securities Trading and Disclosure of Confidential Information policy permits our officers and directors to enter into trading plans designed to comply with Rule 10b5-1.

On November 25, 2024, Lasse Petterson, Director and President and Chief Executive Officer, adopted a Rule 10b5-1 trading arrangement that is intended to satisfy the affirmative defense of Rule 10b5-1 (c) and provides for the sale of up to 250,000 shares of our common stock by May 25, 2025. On November 13, 2024, Eleni Beyko, Senior Vice President, Offshore Energy, adopted a Rule 10b5-1 trading plan arrangement that is intended to satisfy the affirmative defense of Rule 10b5-1 (c) and provides for the sale of 50% of the net shares of our common stock delivered to Dr. Beyko upon the vesting of certain of her outstanding equity awards prior to December 31, 2025.

During the quarterly period ended December 31, 2024, none of our other officers (as defined in Rule 16a-1(f) under the Exchange Act) or directors adopted or terminated a Rule 10b5-1 trading plan or adopted or terminated a non-Rule 10b5-1 trading arrangement (as defined in Item 408(c) of Regulation S-K).
