DISCLOSURE REGARDING CONTROLS AND PROCEDURES

A.    Disclosure Controls and Procedures

        As of the end of the Registrant's fiscal year ended December 31, 2008, an evaluation of the effectiveness of the Registrant'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 the Registrant's principal executive officer and principal financial officer.

NOTICES PURSUANT TO REGULATION BTR

        None.

AUDIT COMMITTEE FINANCIAL EXPERT

        The board of directors of EnerMark Inc., on behalf of the Registrant, has determined that Mr. Robert B. Hodgins, a member and the chairman of the Registrant's Audit & Risk Management Committee, is an "audit committee financial expert" (as such term is defined by the rules and regulations of the Securities and Exchange Commission) and is "independent" (as that term is defined by the New York Stock Exchange's listing standards applicable to the Registrant).

        The Securities and Exchange Commission has indicated that the designation or identification of a person as an "audit committee financial expert" does not (i) mean that such person is an "expert" for any purpose, including without limitation for purposes of Section 11 of the Securities Act of 1933, (ii) impose on such person any duties, obligations or liability that are greater than the duties, obligations and liability imposed on such person as a member of the audit committee and the board of directors in the absence of such designation or identification, or (iii) affect the duties, obligations or liability of any other member of the audit committee or the board of directors.

---

CODE OF ETHICS

        The Registrant has adopted a "code of ethics" (as that term is defined by the rules and regulations of the Securities and Exchange Commission), entitled the "Code of Business Conduct", that applies to each director, officer (including its principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions), employee and consultant of the Registrant. The Code of Business Conduct is available for viewing on the Registrant's website at www.enerplus.com under "Corporate Governance". There were not any amendments to any provision of the Code of Business Conduct during the fiscal year ended December 31, 2008. Further, during the fiscal year ended December 31, 2008, there were not any waivers, including implicit waivers, granted from any provision of the Code of Business Conduct that applied to the Registrant's principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions.

PRINCIPAL ACCOUNTANT FEES AND SERVICES AND
PRE-APPROVAL POLICIES AND PROCEDURES

        The aggregate fees paid by the Registrant to Deloitte & Touche LLP, Independent Registered Chartered Accountants, the Registrant's principal accountant, for professional services rendered in the Registrant's last two fiscal years are as follows:

---

(1)

Audit fees were for professional services rendered by Deloitte & Touche LLP for the audit of the Registrant's annual financial statements and reviews of the Registrant's quarterly financial statements, as well as services provided in connection with statutory and regulatory filings or engagements.

(2)

Audit-related fees are fees for assurance and related services reasonably related to the performance of the audit or review of the Registrant's financial statements and not reported under "Audit Fees" above.

(3)

Tax fees were for tax compliance, tax advice and tax planning. The fees were for services performed by Deloitte & Touche LLP's tax division except those tax services related to the audit.

(4)

All other fees are fees for products and services provided by Deloitte & Touche LLP other than those described as "Audit fees", "Audit-related fees" and "Tax fees".

        The Registrant's Audit & Risk Management Committee has implemented a policy restricting the services that may be provided by the Registrant's auditors and the fees paid to the Registrant's auditors. Prior to the engagement of the Registrant's auditors to perform both audit and non-audit services, the Audit & Risk Management Committee pre-approves the provision of the services. In making their determination regarding non-audit services, the Audit & Risk Management Committee considers the compliance with the policy and the provision of non-audit services in the context of avoiding an adverse impact on auditor independence. All audit and non-audit fees paid to Deloitte & Touche LLP in 2007 and 2008 were pre-approved by the Registrant's Audit & Risk Management 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. Based on the Audit & Risk Management Committee's discussions with management and the independent auditors, the committee is of the view that the provision of the non-audit services by Deloitte & Touche LLP described above is compatible with maintaining that firm's independence from the Registrant.
