Reconciliation of Non-GAAP Measures

LINN Energy

NASDAQ:LINE • NASDAQ:LNCO

The Company defines adjusted EBITDA as net income (loss) plus the following adjustments:

Net operating cash flow from acquisitions and divestitures, effective date through closing date;

Interest expense;

Depreciation, depletion and amortization;

Impairment of long-lived assets;

Write-off of deferred financing fees;

(Gains) losses on sale of assets and other, net;

Provision for legal matters;

Loss on extinguishment of debt;

Unrealized (gains) losses on commodity derivatives;

Unrealized (gains) losses on interest rate derivatives;

Realized (gains) losses on interest rate derivatives;

Realized (gains) losses on canceled derivatives;

Realized gains on recovery of bankruptcy claim;

Unit-based compensation expenses;

Exploration costs; and

Income tax expense (benefit).

Adjusted EBITDA is a measure used by Company management to indicate (prior to the establishment of any reserves by its Board of Directors) the cash distributions the Company expects to make to its unitholders. Adjusted EBITDA is also a quantitative measure used throughout the investment community with respect to publicly-traded partnerships and limited liability companies.

Adjusted net income is a performance measure used by Company management to evaluate its operational performance from oil and natural gas properties, prior to unrealized (gains) losses on derivatives, realized (gains) losses on canceled derivatives, realized gain on recovery of bankruptcy claim, impairment of long-lived assets, loss on extinguishment of debt and (gains) losses on sale of assets, net.

LINN Energy

NASDAQ:LINE • NASDAQ:LNCO

The U.S. Securities and Exchange Commission (“SEC”) permits oil and gas companies, in their filings with the SEC, to disclose only resources that qualify as “reserves” as defined by SEC rules. We use terms describing hydrocarbon quantities in this presentation including “inventory” and “resource potential” that the SEC’s guidelines prohibit us from including in filings with the SEC. These estimates are by their nature more speculative than estimates of reserves prepared in accordance with SEC definitions and guidelines and accordingly are substantially less certain. Investors are urged to consider closely the reserves disclosures in LINN Energy’s Annual Report on Form 10-K for the year ended December 31, 2012, available from LINN Energy at 600 Travis, Suite 5100, Houston, Texas 77002 (Attn: Investor Relations). You can also obtain this report from the SEC by calling 1-800-SEC-0330 or from the SEC’s website at www.sec.gov.

In this communication, the terms other than “proved reserves” refer to the Company’s internal estimates of hydrocarbon volumes that may be potentially discovered through exploratory drilling or recovered with additional drilling or recovery techniques. Those estimates may be based on economic assumptions with regard to commodity prices that may differ from the prices required by the SEC to be used in calculating proved reserves. In addition, these hydrocarbon volumes may not constitute reserves within the meaning of the Society of Petroleum Engineer’s Petroleum Resource Management System or the SEC’s oil and gas disclosure rules. Unless otherwise stated, hydrocarbon volume estimates have not been risked by Company management. Factors affecting ultimate recovery include the scope of our ongoing drilling program, which will be directly affected by the availability of capital, drilling and production costs, commodity prices, availability of drilling services and equipment, drilling results, lease expirations, transportation constraints, regulatory approvals and other factors, and actual drilling results, including geological and mechanical factors affecting recovery rates. Accordingly, actual quantities that may be ultimately recovered from the Company’s interests may differ substantially from the Company’s estimates of potential resources. In addition, our estimates of reserves may change significantly as development of the Company’s resource plays and prospects provide additional data.
