ADDITIONAL DISCLOSURE



Certifications and Disclosure Regarding Controls and Procedures.



| | (a) | Certifications. See Exhibits 99.5, 99.6, 99.7 and 99.8 to this Annual Report on Form 40-F.
| | --- | ------------------------------------------------------------------------------------------



| | (b) | Disclosure Controls and Procedures. As of the end of Bellatrix’s fiscal year ended December 31, 2016, an evaluation
of the effectiveness of Bellatrix’s “disclosure controls and procedures” (as such term is defined in Rules 13a-15(e)
and 15d-15(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) was carried out by Bellatrix’s
management, with the participation of its principal executive officer and principal financial officer. Based upon that evaluation,
Bellatrix’s principal executive officer and principal financial officer have concluded that as of the end of that fiscal
year, Bellatrix’s disclosure controls and procedures are effective to ensure that information required to be disclosed by
Bellatrix in reports that it files or submits under the Exchange Act is (i) recorded, processed, summarized and reported within
the time periods specified in Securities and Exchange Commission (the “Commission”) rules and forms and (ii) accumulated
and communicated to Bellatrix’s management, including its principal executive officer and principal financial officers, to
allow timely decisions regarding required disclosure.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



It should be noted that while Bellatrix’s principal
executive officer and principal financial officer believe that Bellatrix’s disclosure controls and procedures provide a reasonable
level of assurance that they are effective, they do not expect that Bellatrix’s disclosure controls and procedures or internal
control over financial reporting will prevent all errors and fraud. A control system, no matter how well conceived or operated,
can provide only reasonable, not absolute, assurance that the objectives of the control system are met.



| | (c) | Management’s Annual Report on Internal Control Over Financial Reporting. The required disclosure is included under
the heading "Controls and Procedures - Management's Annual Report on Internal Control over Financial Reporting" in Bellatrix’s
Management Discussion and Analysis for the fiscal year ended December 31, 2016, filed as Exhibit 99.2 to this Annual Report on

are consistent with the requirements of Section 303A.09 of the NYSE Listed Company Manual, and which are described under the heading

NYSE Statement of Governance Differences



As a Canadian corporation listed on the New York Stock Exchange,
Bellatrix is not required to comply with most of the NYSE’s corporate governance standards, so long as it complies with Canadian
and Toronto Stock Exchange corporate governance requirements. In order to claim such an exemption, however, Bellatrix must disclose
the significant difference between its corporate governance practices and those required to be followed by U.S. domestic companies
under the New York Stock Exchange’s corporate governance standards.



Bellatrix 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 New York
Stock Exchange’s corporate governance standards, and that summary, entitled “Significant Differences in Bellatrix’s
Corporate Governance Practices Compared to NYSE Corporate Governance Standards”, is available for viewing on Bellatrix’s
website at www.bellatrixexploration.com.



Bellatrix’s corporate governance practices meet or exceed
all applicable Canadian requirements. They also incorporate some best practices derived from the New York Stock Exchange rules
and comply with applicable United States securities laws and rules adopted by the Commission. Further information about Bellatrix’s
corporate governance practices is included under the heading “Statement of Corporate Governance Practices” in Bellatrix’s
Information Circular prepared in respect of its annual meetings of shareholders.
