Toronto, Ontario and Vancouver, British Columbia, Canada 08 December 2014 -- Norbord Inc. ("Norbord") (TSX: NBD) and Ainsworth Lumber Co. Ltd. ("Ainsworth") (TSX: ANS) today announced that they have signed a definitive agreement under which they will merge to create a leading global wood products company focused on oriented strand board ("OSB") across North America, Europe and Asia.

The combination of Norbord and Ainsworth will create one of the largest and lowest-cost OSB producers globally, with a portfolio of high-quality assets that produce a wide range of products for residential, industrial and specialty applications. The transaction is a compelling strategic fit and offers shareholders, customers, employees and other stakeholders of both companies a significant opportunity owing to the highly complementary nature of the respective operations.

Under the terms of the arrangement agreement announced today, Norbord has agreed to acquire all of the outstanding common shares of Ainsworth in an all-share transaction in which Ainsworth shareholders will receive 0.1321 of a Norbord share for each Ainsworth share pursuant to a plan of arrangement under the British Columbia Business Corporations Act. The transaction value represents a premium of 15% to Ainsworth's 20-day volume weighted average price (VWAP), and the transaction has been unanimously approved by the Independent Committees and Boards of Directors (with directors of each company affiliated with Brookfield Asset Management Inc. ("Brookfield") abstaining) of both Ainsworth and Norbord. This all-share transaction structure will allow both Norbord and Ainsworth shareholders to participate in the significant synergies and other benefits expected to result from this combination.

Brookfield and its affiliated entities, which control approximately 55% and 52% of the outstanding common shares of Ainsworth and Norbord respectively, have entered into a binding agreement in which they have committed to vote in favour of the transaction. Upon closing, the Brookfield entities will control approximately 53% of the outstanding common shares of the combined company.

On a pro forma basis, the combined company generated USD $1.63 billion in sales and USD $143 million in Adjusted EBITDA[i] for the 12 months ended September 27, 2014. The transaction is expected to be accretive to earnings and cash flow in the first year.

A Leading Global OSB Company

"This transaction unites two complementary businesses behind a common vision of enhanced service to our customers and growth in North America, Europe and Asia," said Peter Wijnbergen, Norbord's President and Chief Executive Officer. "Norbord and Ainsworth are each low-cost producers in their respective regions, and with our complementary operations and a more diverse range of specialty products, we will be better able to serve our customers across the globe. Ainsworth has excellent mills, a proven track record of innovation in value-added product development, and we look forward to working together. The growth potential we see in the combined company also offers significant value to our shareholders."

Said Jim Lake, Ainsworth's President and Chief Executive Officer: "The combination of the two companies will mean tremendous opportunities for our people and our customers. By joining with Norbord we will be able to leverage its commitment to low-cost operational excellence to expand and improve our existing range of products and enhance our customer relationships. For our shareholders, this transaction offers significant potential for continued value creation as investors in a larger and better-capitalized company with ongoing participation in the current U.S. housing recovery. This is an exciting transaction for Ainsworth and its stakeholders."

Compelling Strategic Fit:

• Geographically Complementary Operations - Norbord and Ainsworth are leading producers in each of their geographies, with minimal overlap. Norbord operates seven North American mills, principally in the U.S. southeast with one mill in Quebec, along with four mills in Europe principally serving the United Kingdom, Germany and the Benelux region. Ainsworth operates four Canadian mills, three in Western Canada and one in Ontario. Together, the combined company will be better positioned to serve national customer accounts and realize savings in freight and logistics costs. With total OSB capacity of approximately 7.7 billion square feet (3/8 inch basis), the combined company will be the largest in the global OSB industry.
• Balanced Portfolio of High Quality Assets - This transaction combines Norbord's low-cost operations and larger mill network with Ainsworth's innovation in value-added strand-based engineered wood products. This will support new product development and allow the combined company to expand the range of specialty products it can offer. The transaction also provides the opportunity to optimize product mix across a broader network of mills to lower manufacturing costs.
• Enhanced Market Diversification - The combined company will be better able to weather market cycles through increased geographic diversification. The transaction will enhance each company's strong North American presence with the more stable margin European operations of Norbord and Asia-focused export business of Ainsworth.
• Strong Financial Position - Norbord and Ainsworth believe that the combined company will have an enhanced credit profile and lower overall cost of capital. The merged entity will focus on maintaining a prudent balance sheet to provide financial flexibility and a solid capital base to support the business through periods of commodity price weakness.
• Growth Potential - The combined company will be well positioned to take advantage of the ongoing recovery in the U.S. housing market and growing OSB demand in Europe and Asia. Together, the company will have opportunities to increase capacity through the expansion of Norbord's OSB production in Western Europe, the restart of Norbord's two idled mills in North America, and the completion of Ainsworth's second line in Grand Prairie, Alberta.
• Improved Capital Markets Presence - The combined company will have a broader shareholder base with increased market liquidity and a larger public float. As of December 5, 2014 the combined company had a pro forma market capitalization of approximately CAD $2.0 billion. The combined company is expected to remain a member of the S&P/TSX Composite index which provides increased visibility and broader market participation.
• Synergies - Management expects that the combined company will deliver significant cost savings through substantial operating synergies estimated at approximately USD $45 million annually, achievable over an 18-24 month period. These savings are expected to come primarily from best practices and technology transfers in the companies' mills, sales and logistics improvements, and cost reductions.

The combined company will operate under the Norbord name, and Norbord's CEO Peter Wijnbergen will lead the business following the close of the transaction while drawing upon the extensive strategic, operating and financial experience of both Norbord and Ainsworth. Ainsworth's CEO Jim Lake has agreed to stay on with the combined company in an advisory capacity for a period of six months. As part of its strategy to continue growing exports to Asia, the combined company will maintain an office in Vancouver, B.C.

The Board of Directors of the combined company will have equal representation of independent directors from the current Norbord and Ainsworth Boards of Directors, with a majority of the Board comprised of directors who are not Brookfield nominees.
