CALGARY - OBSIDIAN ENERGY LTD. (TSX: OBE) (OTCQX: OBELF) ('Obsidian Energy', 'we', or 'our') today wrote the following letter to Bonterra Energy Corp. ('Bonterra') shareholders to ensure they had a clear understanding of the benefits of being part of the Cardium Champion, they were aware of the actions of the Bonterra Board of Directors and that they were able to make their own, fully-informed decision on Obsidian Energy's offer (the 'Offer') to purchase all of the outstanding Bonterra common shares ('Bonterra Shares') in consideration for two Obsidian Energy common shares ('Obsidian Shares') for each Bonterra Share tendered to the Offer.

As set out in further detail in the Offer Documents, the Offer is subject to certain conditions, including: that the Bonterra Shares validly deposited to the Offer, and not withdrawn, represent at least 66 2/3% of the then outstanding Bonterra Shares (on a fully-diluted basis) and certain regulatory and third party approvals (as outlined in the Offer Documents) shall have been obtained, including Obsidian Energy shareholders approving, as required by the rules of the Toronto Stock Exchange, the issuance of the Obsidian Shares to be distributed by Obsidian Energy in connection with the Offer, and other customary conditions.

NON-GAAP MEASURES

This news release contains references to the terms EBITDA, Enterprise Value (or EV), Net Debt, Debt, funds flow, cash flow, free cash flow, and netbacks which do not have a standardized meaning prescribed by International Financial Reporting Standards and therefore are considered non-GAAP measures; accordingly, they may not be comparable to similar measures provided by other issuers. EBITDA is net earnings (loss) plus finance expenses (income), provisions for (recovery of) income taxes, and depletion, depreciation and amortization. Enterprise Value is a measure of total value of the applicable company calculated by aggregating the market value of its common shares at a specific date, adding its total Debt and subtracting its cash and cash and cash equivalents. Debt is bank debt, notes and, solely in respect of Bonterra, subordinated debt (including the subordinated note(s) issued by Bonterra to private related party investors). Net Debt is bank debt or long-term debt, plus net working capital (surplus)/deficit, and is a measure of leverage and liquidity. Funds flow is cash flow from operating activities before changes in non-cash working capital, decommissioning expenditures, onerous office lease settlements, the effects of financing related transactions from foreign exchange contracts and debt repayments, restructuring charges and certain other expenses and is representative of cash related to continuing operations. Funds flow is used to assess the combined entity's ability to fund planned capital programs. Cash flow is funds flow from operations before changes in any non-cash working capital changes and decommissioning expenditures. Free cash flow is funds flow from operations less capital and decommissioning expenditures. Netback is the per unit of production amount of revenue less royalties, operating expenses, transportation expenses and realized risk management gains and losses, and is used in capital allocation decisions and to economically rank projects.
