We are continuously evaluating our anti-corruption measures and performance. ANTI-CORRUPTION AND TRAINING All Kosmos employees, board members, and individual contractors are required to attend yearly anti- corruption training, and certify that they have read, understood, and will comply with our Anti-Corruption Compliance Policy. To further ensure comprehension, all of our employees are required to pass a test on the Anti-Corruption Compliance Policy. We exercise care in the selection of vendors, suppliers, and contractors, and we impose the same high standards of conduct that we observe in our own company. We use a risk-based process to evaluate third parties who will work on our behalf. We conduct background due diligence when appropriate to make sure we have obtained full disclosure. In addition to providing all third parties with copies of our Business Principles and Anti-Corruption Compliance Policy, we routinely conduct in-country contractor and supplier training on compliance and supplement in-person training with online training modules. We conduct rigorous due diligence on potential partners as we seek to expand our exploration portfolio. In some cases, we have decided not to pursue new ventures when we were uncomfortable with a potential partner’s standards. We conduct an annual internal audit of the company’s compliance with its business ethics policies and periodically conduct audits on third parties. We maintain a Whistleblower Hotline as a vehicle for employees, third parties and others to report, without risk of retaliation, potential violations of any Kosmos policy. TRANSPARENCY Kosmos continues to be an industry leader in promoting transparency by disclosing the terms of all of our petroleum agreements and reporting payments made to our host governments around the world. We are a Supporting Company of the Extractive Industries Transparency Initiative (EITI). Kosmos is a member of the EITI Steering Committees in Ghana and Mauritania and plays an active role in the EITI process in Senegal and São Tomé and Príncipe. We advocate for the adoption of EITI in all of the countries where we operate, where possible. Kosmos discloses payments to governments at a project level, as laid out in the European Union Accounting Directive, an initiative that aims to improve corporate accounting practices and transparency. Our project level disclosures are available on our website: http://www.kosmosenergy. com/responsibility/transparency.php. This type of disclosure is beneficial to investors, civil society, and local communities and reflects evolving international expectations. In October 2015, Kosmos submitted a comment letter to the United States Securities and Exchange Commission (SEC) as part of the SEC rulemaking process for Section 1504 of the Dodd-Frank Wall Street Reform and Consumer Protection Act, which proposes requiring U.S.-listed companies to disclose payments to U.S. and foreign governments as a standard part of their reporting to the SEC. In our comment letter to the SEC, we highlighted our commitment to transparency, including our project level disclosure in accordance with the EU Accounting Directive. We stated that we believe that this type of disclosure is beneficial to investors, civil society, and local communities, and reflects evolving international expectations. A copy of this letter is available on our website at responsibility/transparency.php. ETHICAL CONDUCT PRINCIPLE BUSINESS 2 “Kosmos is determined to operate in a corruption-free environment and we take great care to ensure that our co-venture partners, employees, contractors and vendors are all aware of their obligation to operate ethically. Having vocal support for this approach from the highest levels at the company enables us to instill an ethical mindset in every employee. RICHARD STEPHENS Manager, Legal Compliance Kosmos Energy All Kosmos employees – regardless of role or work location – are required to complete anti-corruption training.
