Each Party shall devise and maintain a system of internal accounting controls sufficient to meet the accounting requirements and satisfy the laws of the country where it is incorporated. Each Party shall inform the other Party, if not prohibited by applicable laws, of any situation of which it becomes aware that may result in a breach of this Clause.

This includes offering, making, promising, or authorizing any benefit or advantage, directly or indirectly, to any employee, officer, official, agent or representative of the other Party, to any actual or potential customer of either Party, or to any “Government Official” under any circumstances where one could reasonably anticipate such action may potentially impact a business decision of either Party in the context of this Agreement or the subject matter hereof. For the purpose of this Agreement, “Government Official” means (a) an officer or employee of any national, regional, local, or other government of any country, (b) an officer or employee of any department, agency or instrumentality of said government, including any elected or appointed official in any branch (executive, legislative, or judiciary), (c) an officer or employee of a company or enterprise owned or controlled by or performing a function of a government, (d) an officer or employee of a public or state-sponsored university or research organization, (e) an officer or employee of a public international organization, (f) a candidate for political office, (g) a political party or political party official, (h) a member of a royal family or member of the military, (i) an individual otherwise categorized as a Government Official under applicable local laws, and (j) to any other person, individual or entity at the suggestion, request or direction or for the benefit of, or any other person acting in an official capacity for or on behalf of, any of the persons described in (a) through (i) above.

If either Party has reason to believe based on credible evidence that any of the representations or warranties regarding compliance with laws in this Agreement are or become inaccurate or misleading, such Party may suspend all performance under this Agreement until it has received confirmation to its satisfaction that no breach has occurred or is likely to occur and may request additional representations and warranties reasonably
