DISCLOSURE CONTROLS AND PROCEDURES

Vermilion Energy Inc. (the "Registrant")
maintains disclosure controls and procedures designed to ensure that information required to be disclosed in the Registrant's filings
under the Securities Exchange Act of 1934, as amended (the "Exchange Act") is recorded, processed, summarized and reported
within the time period specified in the rules and forms of the Securities and Exchange Commission (the "Commission").
Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required
to be disclosed by the Registrant in the reports that it files or submits under the Exchange Act is accumulated and communicated
to the issuer's management, including its principal executive and principal financial officers, or persons performing similar functions,
as appropriate to allow timely decisions regarding required disclosure. The Registrant's Chief Executive Officer and Chief Financial
Officer, after having evaluated the effectiveness of the Registrant's disclosure controls and procedures (as defined in Exchange
Act Rules 13a-15(e) and 15d-15(e)) as of the end of the period covered by this report have concluded that, as of such date, the

NOTICES REQUIRED BY RULE 104 OF REGULATION
BTR



None



AUDIT COMMITTEE FINANCIAL EXPERT



The Registrant's Board of Directors has determined
that it has at least one audit committee financial expert (as such term is defined in the rules and regulations of the Commission)
serving on its Audit Committee. Catherine L. Williams has been determined to be such audit committee financial expert and is independent
(as such term is defined by the New York Stock Exchange's corporate governance standards).



The Commission has indicated that the designation
of Catherine L. Williams as an audit committee financial expert does not make her an "expert" for any purpose, impose
on her any duties, obligations or liability that are greater than the duties, obligations or liability imposed on her as a member
of the Audit Committee and the Board of Directors in absence of such designation, or affect the duties, obligations or liability
of any other member of the Audit Committee or Board of Directors.



CODE OF ETHICS



The Registrant has adopted a written “code
of ethics” (as that term is defined in Form 40-F) that applies to its directors, officers and employees, including its principal
executive officer, principal financial officer, principal accounting officer or controller, and persons performing similar functions. 
A copy of such code of ethics is available upon request or on the Registrant’s website at www.vermilionenergy.com.
In 2017, there were no amendments to the code of ethics or waivers, including implicit waivers, from any provision of the code
of ethics.





PRINCIPAL ACCOUNTANT FEES AND SERVICES



See page 59
of the Annual Information Form for the year ended December 31, 2017 included as Exhibit 99.1 to this report.



The Audit Committee pre-approves all audit related
fees. The auditors present the estimate for the annual audit related services to the Audit Committee for approval prior to undertaking
the annual audit of the financial statements.



All non-audit fees were pre-approved by the
Audit Committee and none were approved on the basis of the de minimis exemption set forth in Rule 2-01(c)(7)(i)(C) of Regulation
S-X .



OFF-BALANCE SHEET ARRANGEMENTS



The Registrant has not entered into any off
balance sheet arrangements that have or are reasonably likely to have a current or future effect on its financial condition, changes
in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that
are material to investors.

IDENTIFICATION OF THE AUDIT COMMITTEE



The Registrant’s Board of Directors has
a separately designated standing Audit Committee established in accordance with Section 3(a)(58)(A) of the Exchange Act which
satisfies the requirements of Exchange Act Rule 10A-3. The Registrant’s Audit Committee is comprised of Catherine L. Williams
(Chair), Stephen P. Larke, Larry J. Macdonald, and Robert B. Michaleski, all of whom, in the opinion of the Registrant’s
Board of Directors are independent (as determined under Rule 10A-3 of the Exchange Act and the corporate governance standards of
the NYSE) and are financially literate.





NYSE STATEMENT OF GOVERNANCE DIFFERENCES



As a Canadian corporation with securities listed
on the Toronto Stock Exchange (“TSX”) and the New York Stock Exchange (“NYSE”), the Registrant is required
to comply with all applicable Canadian requirements adopted by the Canadian Securities Administrators and the TSX, and applicable
rules for foreign private issuers adopted by the Commission which give effect to the provisions of the Sarbanes-Oxley Act of 2002
(“Sarbanes-Oxley”).



The Registrant’s corporate governance
practices meet or exceed all applicable Canadian and Sarbanes-Oxley requirements and also incorporate many “best practices”
derived from those required to be followed by U.S. domestic companies under the NYSE listing standards. In accordance with Section
303A.11 of the NYSE Listed Company Manual, the Registrant has prepared a summary of the significant ways in which its corporate
governance practices differ from those required to be followed by U.S. domestic companies under the NYSE’s corporate governance
standards, which is accessible on the Registrant’s website at http://www.vermilionenergy.com/about/governance.cfm.
