AUDIT COMMITTEE

TERMS OF REFERENCE

ORGANIZATION

Enerflex Ltd. (the “Corporation”) has established an Audit Committee of the Board of Directors. These terms of reference govern the operations of the Audit Committee (the “Committee”), as approved by the Board of Directors (the “Board”) of the Corporation. The Committee shall review and reassess the terms of reference annually. The Committee shall be appointed by the Board and shall be comprised of at least three directors, each of whom are independent (as defined by applicable legislation and the applicable rules of any stock exchange on which securities of the Corporation are listed and posted for trading). All Committee members shall have a sufficient level of financial literacy to understand the issues to be raised in the Corporation's financial statements, and at least one Committee member shall have accounting or related financial expertise.

Principal duties of the Committee include oversight responsibility for: financial statements and related disclosures, reports to shareholders and other related communications, establishment of appropriate financial policies, the integrity of accounting systems and internal controls, approval of all audit and non-audit services provided by the independent auditor, consultation with the auditor independent of management and overseeing the work of the independent auditor, and monitoring and directing, as appropriate, the activities of the Internal Audit group.

STATEMENT OF POLICY

The Committee will provide assistance to the Board in fulfilling their oversight responsibility relating to the integrity of the Corporation's financial statements and the financial reporting process, the systems of internal accounting, internal control over financial reporting (“ICFR”), financial controls, the annual independent audit of the Corporation's financial statements and ICFR, and any legal compliance or ethics programs as established by management and the Board. In so doing, it is the responsibility of the Committee to maintain free and open communication between the Committee, the independent auditor and management of the Corporation. In discharging its oversight role, the Committee is empowered to investigate any matter brought to its attention with full access to all books, records, facilities, and personnel of the Corporation and the power to retain and pay outside counsel, or other experts it determines necessary to carry out its duties.

RESPONSIBILITIES AND PROCESSES

The primary responsibility of the Audit Committee is to oversee the Corporation's financial reporting process on behalf of the Board and report the results of their activities to the Board. Management is responsible for the preparation, presentation and integrity of the Corporation's financial statements and for the appropriateness of the accounting principles and reporting policies that are used by the Corporation. The independent auditor is responsible for auditing those financial statements. The Committee, in carrying out its responsibilities, believes its policies and procedures should remain flexible, in order to best react to changing conditions and circumstances. The Committee should take the appropriate actions to set the overall corporate "tone" for quality financial reporting, sound business risk practices, and ethical behaviour.

The following shall be the principal recurring processes of the Committee in carrying out its oversight responsibilities. The processes are set forth as a guide with the understanding that the Committee may supplement them as appropriate.

The Committee shall assure itself that the external auditor is independent from management and the Corporation and will have access to all information about the audit firm's relationship with the Corporation that is necessary to come to a reasonable conclusion.
