公司治理框架手册

Issue Date: February 2021

1. Introduction Corporate governance is a system of policies, procedures, and rules that direct and control a business’s behaviour. It is the framework that defines the relationship between the investors, management, board of directors and other key stakeholders of the company. Good corporate governance fosters a culture of integrity and sustainable business practices within an organization and has been proven to lead to an organization’s positive performance. Good governance signals to the market that an organisation is well managed and that the interests of management are aligned with the broader stakeholders of the business. As such, it can provide businesses with a competitive advantage and is essential for the long-term success of any company. 2. Applicability & Adoption The Board of Managers (the “GP Board”) of Stonepeak DEA Cayman GP LLC (the “Company”), acting in its capacity as the general partner of DEA TopCo LP (the “Partnership” and, together with its subsidiaries and the Company, the “Partnership Group”), has adopted the following Corporate Governance Guidelines (these “Guidelines”) to emphasize the GP Board’s strong commitment to good governance practices. DEA TopCo LP, is an exempted limited partnership formed in the Cayman Island pursuant to an Amended and Restated Exempted Limited Partnership Agreement (the “Partnership Agreement”), dated January 3, 2020, by and among the Company, Stonepeak DEA Holdings (Cayman) LLC (the “Stonepeak Limited Partner”), and the other parties listed as limited partners on Schedule I thereto (collectively with the Stonepeak Limited Partners, the “Limited Partners”). By contract, the Limited Partners do not participate in the management of the Partnership, nor in the selection or election of directors to the GP Board. The basic charter document for the General Partner is its First Amended and Restated Limited Liability Company Agreement, dated January 3, 2020, as may be amended from time to time (the “LLC Agreement”). The sole member of the Company has delegated to the GP Board its power and authority to manage and control the business and affairs of the Partnership Group. Pursuant to these agreements, the corporate governance of the Company is, in effect, the corporate governance of the Partnership. These Guidelines have been adopted by the GP Board and, together with with the Partnership Agreement, the LLC Agreement, the charters of the GP Board’s committees and other written governance policies of the Partnership Group, are designed to provide a framework for the functioning of the GP Board and its committees, as well as the overall management of the Partnership Group. Guidelines 3.1 Mission The Partnership Group aspires to achieve the highest standards of ethical conduct, reporting results with accuracy and transparency, and maintaining full compliance with the laws, rules and regulations that govern the Partnership Group’s businesses. 3.2 Board of Managers The principal decision-making body of the Partnership is the Company, through its GP Board. The number of managers that constitutes the GP Board will be fixed from time to time pursuant to the LLC Agreement and Partnership Agreement. The GP Board has responsibility for setting the strategic direction of the Partnership and for ensuring that risk is managed effectively. The GP Board is accountable to the Partnership for the group’s financial and operational performance. Pursuant to the Partnership Agreement, the GP Board is supported by two committees: The Compensation Committee and the CapEx Committee. The GP Board has delegated responsibility for implementing the operational decisions and the day-to-day management of the business to the Chief Executive Officer (“CEO”). The CEO has constituted seven subcommittees to aid in the formulation and execution of day-to-day management decisions. 3.3 Role of the GP Board The role of the GP Board is to provide leadership of the Partnership and direction for management. The GP Board is collectively responsible and accountable to the Partnership’s unitholders and other stakeholders for the long-term sustainable success of the group, for generating value, contributing to wider society and for ensuring the group is appropriately managed and operates responsibly, with effective controls, as it pursues its objectives. The GP Board reviews the performance of management and the operating and financial performance of the group. In particular, the GP Board is responsible for establishing the Partnership’s purpose and values and setting strategy, determining risk appetite, ensuring appropriate risk management and internal controls are in place, ensuring good governance, decision making and promoting the desired culture. The GP Board also ensures that plans are in place for orderly succession for appointments to the board and to senior management, to maintain an appropriate balance of skills and experience within the Partnership and on the GP Board. 3.4 Selection and Role of Chairman The GP Board selects the Chairman of the Board amongst its members in the manner set forth in the Partnership Agreement. The Chairman is not entitled to a second or casting vote at any meeting of the GP Board. The Chairman leads the GP Board and is responsible for ensuring an effective board and effective contributions from individual managers, particularly non-executive managers, based on a culture of mutual respect, openness, debate and constructive challenge. To achieve this, the Chairman seeks to facilitate and encourage open communication and constructive working relations between the GP Board and management of the Partnership. The Chairman is responsible for setting the GP Board’s agenda and ensuring that there is adequate time to discuss all agenda items. In addition, the Chairman monitors, with assistance from the Company Secretary, the information distributed to the board to ensure it is of high quality, accurate, clear, and timely. The GP Board has no policy with respect to the separation of the offices of Chairman and Chief Executive Officer. The GP Board believes that this issue is part of the succession planning process and that it is in the best interests of the Partnership and its unitholders for the GP Board to decide each time it elects a new Chief Executive Officer, or at such other times as when consideration of the matter is warranted under the circumstances. With that said, there is a clear division between the Chairman’s responsibilities for running the board and the Chief Executive’s role for the running of the business. This division of responsibilities is established in a written statement which can be found in Schedule 1 of these Guidelines. 3.5 Selection of GP Board Members The GP Board nominates board candidates for election taking into consideration the requirements of the Partnership Agreement. Non-Executive Board Members The role of the non-executive board member is to scrutinise management’s performance in meeting agreed goals and objectives and to monitor how that performance is reported. They must also be satisfied with the integrity of the group’s financial information on the effectiveness of financial controls and risk management systems. As members of the GP Board, the non-executive board members bring independent judgment and a range of experience to the board and therefore have a key role in constructively challenging in all areas. This is vital to the independence and objectivity of the board’s deliberations and decision making and is particularly important in helping develop proposals on strategy. The non-executive board members’ role is to support the decisions that have been taken and to support the executive team in their delivery. Executive Board Members Executive board members have specific responsibilities relating to the Group’s business, however, as board members their duties extend beyond their own businesses to include the whole of the Group’s operations and activities. Company Secretary The Company Secretary is secretary to the GP Board and its committees. The Company Secretary reports to the Chairman on board governance matters and, together with the Chairman, keeps the efficacy of the Partnership’s and the GP Board’s governance processes under review and recommends improvements where necessary. The Company Secretary is also responsible to the board for compliance with board procedures and, through the Chairman, for advising and keeping the board up to date on all legislative, regulatory and governance matters and developments applicable to the business of the Partnership. 3.6 Board Members’ Responsibilities The basic responsibility of each board member, when causing the Partnership to act in its capacity as general partner of the Partnership, is to act in good faith, as that term is used in the Partnership Agreement. In discharging this obligation, board members should be entitled to rely on the honesty and integrity of the senior executives and the outside advisors and auditors for the Partnership Group. GP Board members are expected to attend GP Board meetings and meetings of committees on which they serve and to spend the time needed and meet as frequently as necessary to properly discharge their responsibilities. Information and data that are important to the GP Board’s understanding of the business to be conducted at a GP Board or committee meeting should generally be distributed in writing to the directors before the meeting, and board members should review these materials in advance of the meeting. GP Board members’ attendance at GP Board and committee meetings should be considered by the full GP Board in assessing each director’s performance. 3.7 Decisions Making at the Board All matters which are not specifically described in the Partnership Agreement as requiring some other specified approval, shall be approved by the GP Board acting through a majority. The GP Board is also authorized to act by unanimous decision via circular resolution. 3.8 Board Reserved Matters Details of the decisions which can only be taken by the GP Board and the role and duties of the committees are more fully set out in the Partnership Agreement.

3.9 Board Meetings GP Board members are expected to attend board meetings and to spend the time needed and meet as frequently as necessary to properly discharge their responsibilities. Information and materials that are important to the GP Board’s understanding of the business to be conducted at a GP Board meeting should be distributed to the members at least five (5) business days prior to regularly scheduled board meetings and two (2) business days prior to special board meetings, to provide ample time for review beforehand. The Chairman shall establish a calendar of standard agenda items to be discussed at each meeting scheduled to be held over the course of the ensuing year and shall also establish the agenda for each GP Board meeting. Each GP Board member is free to suggest items for inclusion on the agenda or to raise subjects that are not on the agenda for that meeting. Board Meetings – Frequency The GP Board will generally hold five (5) regularly scheduled meetings per year and will hold additional special meetings, as necessary. Each GP Board member is expected to attend both scheduled and special meetings, except if unusual circumstances make attendance impractical. Board Meetings – Agenda The CEO, in consultation with the Chairman, will set the agenda for each GP Board meeting taking into account suggestions from other GP Board members. Board Meetings – Minutes Minutes with respect to actions/decisions taken at each meeting of the GP Board shall be recorded by the Company Secretary and will be circulated within five (5) business days of the meeting to the Chairman for review and approval. Once approved, the minutes will be circulated to all GP Board members and included in the papers for the next full GP Board meeting for noting. 3.10 Annual Strategic Review The GP Board shall review the Partnership’s long-term strategic plans and the principal issues that it expects the Partnership Group may face in the future during at least one GP Board meeting each year. 3.11 Access to Senior Management The GP Board shall have full and free access to senior management and other employees of the Partnership Group. Any meetings or contacts that a GP Board member wishes to initiate may be arranged through the CEO or the Company Secretary or directly by the GP Board member.

The results of the review of GP Board performance shall be summarized and presented to the GP Board. 3.16 Term Limits The GP Board does not believe it should limit the number of terms for which an individual may serve as a board member. Members who have served on the GP Board for an extended period are able to provide valuable insight into the operations and future of the Partnership based on their experience with and understanding of the Partnership’s history, policies, and objectives. The GP Board believes that, as an alternative to term limits, it can ensure that the GP Board continues to evolve and adopt new viewpoints through the evaluation and development process described in these guidelines. 3.17 Board Committees The GP Board has two committees: The Compensation Committee and the CapEx Committee to which it delegates certain tasks. Each committee shall be composed of three members of the GP Board, each of whom is to be appointed in accordance with the terms of the Partnership Agreement. Each Committee member shall be appointed until such time as the member has resigned or has been otherwise removed by the GP Board. No one other than the board committee chairman and committee members is entitled to be present at committee meetings. Others may attend, but only by invitation. The GP Board may establish additional committees as necessary or appropriate. 3.18 Committee Charters Each committee will have its own charter setting forth the authority and responsibilities of the committee as well as qualifications for committee membership, procedures for committee member appointment and removal, committee structure and operations and committee reporting to the GP Board. Other committees established by the GP Board may also have committee charters setting forth similar provisions. 3.19 Committee Meetings The Chairman of each committee, in consultation with the committee members, will determine the frequency and length of the committee meetings consistent with any requirements set forth in the committee’s charter. The Chairman of each committee, in consultation with the appropriate members of the committee and management, will develop the committee’s agenda. Committee members are free to suggest the inclusion of items on the agenda and may raise at any Committee meeting subjects that are not on the agenda for that meeting. The GP Board shall ensure that its committees are provided with sufficient resources to undertake their duties, including access to the services of the Company Secretary as required. Each committee has the authority to seek any information that it requires from any officer or employee of the Partnership or its subsidiaries. Each committee is also authorised by the GP Board to take independent advice (including legal or other professional advice), at the Partnership’s expense, as it considers necessary. Each committee may request information from, or commission investigations by, external advisers. The committees formally report to the GP Board on their proceedings after each meeting and generally on all matters and activities for which they are responsible through the committee chairmen and via committee minutes. 3.20 Annual Performance Evaluation of the Committees Each year, the GP Board will conduct the annual performance review of the GP Board’s standing committees. As part of this process, the Chairman of each standing committee will report to the full GP Board about the committee’s annual evaluation of its performance and evaluation of its charter. 3.21 Code of Conduct The Partnership has adopted a Business Code of Conduct (the “Code”) and other internal policies and guidelines, consistent with the Partnership’s purpose and values, and to comply with the laws, rules and regulations that govern the Partnership Group’s business operations. The Code applies to all employees, temporary workers and other independent contractors and consultants when engaged by, or otherwise representing, the Partnership and its interests. The GP Board shall monitor compliance with the Code of Conduct on an on-going basis. 3.22 Conflict of Interest No member of GP Board shall derive any personal profit or gain, directly or indirectly, by reason of his or her participation with the Partnership (other than his or her holding units in the Partnership itself). This shall also include the GP Board member’s business or other non-profit affiliations, family and/or significant other, employer, or close associates who may stand to receive a benefit or gain. Each individual GP Board member and CEO shall disclose to the full GP Board any personal interests which he or she may have in any matter pending before the organization and shall refrain from participation in any discussion or decision on such matter. 3.23 Investments GP Board members and members of senior management may not invest in partnerships or other investment opportunities sponsored, or otherwise made available, by the Partnership, unless their participation is approved in advance by the GP Board or is otherwise allowed by the Partnership Agreement. GP Board members and members of senior management may not invest in a third-party entity when the investment opportunity is made available to him or her as a result of such individual’s status as a GP Board member or member of senior management of the Partnership, except as otherwise may be allowed under the Partnership Agreement. 3.24 Role of CEO The GP Board has delegated responsibility for implementing operational decisions and the day-to-day management of the business to the CEO who, in turn, is supported by seven sub-committees formed under the direction of the CEO. Chief Executive Officer The CEO has the broad authority from the GP Board to run the day-to-day operations of the Partnership Group and he is accountable for, and reports to the GP Board on, how it is performing. The CEO also has a key role in the process for the setting and review of strategy. In addition, he is responsible for ensuring that the executive managers’ views on business issues and views from the workforce on relevant issues are shared with the board in a fair and balanced way. Executive committees Although the CEO is responsible for implementing the day-to-day management of the operations of the Partnership Group, the CEO has established seven sub-committees to assist him with setting and implementing the strategic goals and day-to-day operational decisions of the Partnership. Decision making at each subcommittee is determined by majority of the Committee Members in attendance, provided however, the CEO shall have a casting vote on those committees on which he serves as well as a veto over all decisions made by the committees. In the event the CEO has exercised his veto powers, the CEO shall issue a veto statement to the committee and the matter so vetoed shall be sent back to the relevant committee for further evaluation and discussion until such time as a decision can be made in accordance with the committee charter. The scope and responsibility of each executive sub-committee is briefly described below.
