Item 9B. Other Information.

As disclosed in this Report under “Business -- Legal Proceedings," following receipt of information regarding potential improper payments being made by third party sales representatives of our Refining Solutions business, we promptly retained outside counsel and forensic accountants to investigate potential violations of our Code of Conduct, the Foreign Corrupt Practices Act and other potentially applicable laws. Based on this internal investigation, we voluntarily self-reported potential issues relating to the use of third party sales representatives in our Refining Solutions business to the DOJ and the SEC and intend to cooperate with the DOJ and the SEC in their review of these matters.

Our Board of Directors has determined, as a prudent governance measure while the investigation is pending, to condition payment of each Named Executive Officer’s (as defined below) cash incentive bonus for the fiscal year 2017 (the “2017 cash incentive”) on each Named Executive Officer executing a clawback agreement applicable to the 2017 cash incentive. Accordingly, on February 26, 2018, the Company entered into a clawback agreement with each of Ms. Narwold and Messrs. Kissam, Tozier, Juneau and LaBauve (each a "Named Executive Officer"). The clawback agreements supplement the Company’s existing clawback policy and provide that each Named Executive Officer's 2017 cash incentive is subject to clawback by the Company in the event that the Executive Compensation Committee of the Board determines that, with respect to the Company’s internal investigation or the government’s review of these matters following such self-report, the Named Executive Officer: (1) engaged in unlawful conduct or misconduct; (2) failed to cooperate in any related investigation; (3) violated the Company’s Code of Conduct or any other Company policy; or (4) failed to exercise appropriate supervision or oversight.
