DISCLOSURE CONTROLS AND PROCEDURES

A. Evaluation of Disclosure Controls and Procedures



Vermilion Energy Inc. (the "Registrant")
maintains disclosure controls and procedures and internal control over financial reporting 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 an issuer 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 Registrant's disclosure controls and procedures are effective.

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
andregulations of the Commission) serving on its Audit Committee. Joseph F. Killi 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 Joseph F. Killias an audit committee financial expert does not make him an "expert"
for any purpose, impose on him any duties, obligations or liability that are greater than the duties, obligations or liability
imposed on him 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. A copy of such code of ethics is available upon request or on the Registrant’s website at www.vermilionenergy.com.



PRINCIPAL
ACCOUNTANT FEES AND SERVICES

50 of the Annual Information Form for the year ended December 31, 2014 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

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 Joseph F. Killi
(Chair), W. Kenneth Davidson, Claudio A. Ghersinich, Larry J. Macdonald and William F. Madison, 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.
