(1) Attributable to shareholders of Boralex for continuing operations

(2) Given that June 30, the scheduled date for payment of $8.3 million in interest on convertible debentures, fell on a Sunday before a statutory holiday, the payment was made on July 2, 2013. Adjusted cash flows from operations are thus $9.5 million.

The improvement in the Corporation's performance in the second quarter of 2013 resulted in large part from the contribution of the St-Patrick wind farm in France acquired in June 2012, as well as from better wind conditions in Canada and more favourable water flows in the U.S., which more than offset the impact of the shutdown of operations at the Kingsey Falls thermal power station. In the second quarter of 2013, these positive factors sparked improvements in the Corporation's production, revenues from energy sales, EBITDA and cash flows from operations(2) of 9%, 3%, 23% and 73%, respectively, compared with the same period of 2012.

In the second quarter of 2013, Boralex closed US$90 million in long-term financing secured by two of its U.S. power stations which will allow the Corporation to repay a US$70.7 million existing loan facility and free up funds to support its development. This non-recourse financing will bear interest at an annual rate of 3.51% and will be amortized by semi-annual payments over a 12-year period.

A GROWING COMPANY: SEVERAL SITES UNDER CONSTRUCTION

The Corporation continues to develop several projects in Canada and France, which will significantly influence its asset profile in the next few years. "Construction of Phase I of the Seigneurie de Beaupré Wind Farms is still on schedule despite a one-week work

shutdown caused by a general strike in Québec's construction industry last June," said Boralex President and CEO Patrick Lemaire. The first 272 MW will be commissioned in December 2013 followed by an additional 68 MW with the Phase II in December 2014. Elsewhere in Canada, construction is expected to begin on the Témiscouata I wind farm in the third quarter. Work is on schedule at the Jamie Creek hydroelectric site, which the Corporation expects to commission in early 2014.

In France, construction continues at the La Vallée and Vron wind farms, with commissioning still scheduled for late 2013. The Corporation is currently actively working at finalizing the financing for the Fortel-Bonnières and St-François projects.

As of June 30, 2013, Boralex can count on $128 million in available cash to fuel its growth.
