 public companies in the energy sector, including her current experience as President and Chief Executive Officer of Marathon Petroleum and MPLX LP, with oversight of the largest refinery in the U.S., enables her to contribute important insights to the Board regarding international business strategy and management of public companies. As the Company continues on its transformation journey, Ms. Mannen’s extensive executive-level experience provides valuable knowledge and guidance to the Board as the Company executes on the Masonite integration and streamlines operations to reduce duplicate spending and leveraging the Company’s enterprise scale for future growth. Additionally, Ms. Mannen’s role as President and Chief Executive Officer of Marathon Petroleum and MPLX LP, which includes oversight responsibilities for matters related to health, environment, safety and security, provides the Board with additional insights into the Company’s sustainability strategy and initiatives. As the former Chief Financial Officer of Marathon Petroleum and TechnipFMC, she brings extensive financial and risk management experience to the Board, which is important as the Company navigates growth and strengthens its core markets. Ms. Mannen’s financial expertise and strong knowledge of accounting systems and controls enable her to provide the Board and management with strong oversight of the management of the Company’s assets and specifically in her role as Chair of the Audit Committee. 
 Ms. Mannen’s financial management experience and extensive knowledge of accounting led to her designation as an “audit committee financial expert” and Chair of the Audit Committee.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
 *Our Board views Ms. Mannen’s service on the board of MPLX LP, which is a wholly-owned subsidiary of Ms. Mannen’s current employer, as an extension of her senior executive role with its parent company and not as a separate outside board because her responsibilities substantially overlap and require minimum extra work to her current responsibilities at Marathon Petroleum.
