Capital Power Income L.P. Acquisition Overview

On June 20, 2011, Atlantic Power, CPILP, CPI Income Services Ltd., the general partner of CPILP, and CPI Investments Inc., a unitholder of CPILP that is owned by EPCOR Utilities Inc. and Capital Power Corporation, entered into an Arrangement Agreement (the “Arrangement Agreement”), which provides that Atlantic Power will acquire, directly or indirectly, all of the issued and outstanding CPILP units pursuant to a plan of arrangement (the “Plan of Arrangement”) under the Canada Business Corporations Act. Under the terms of the Plan of Arrangement, CPILP unitholders will be permitted to exchange each of their CPILP units for, at their election, Cdn$19.40 in cash or 1.3 Atlantic Power common shares. All cash elections will be subject to proration if total cash elections exceed approximately Cdn$506.5 million and all share elections will be subject to proration if total share elections exceed approximately 31.5 million Atlantic Power common shares. In connection with Atlantic Power’s acquisition of CPILP, CPILP will sell its Roxboro and Southport facilities located in North Carolina (the “North Carolina Assets”) to an affiliate of Capital Power Corporation (TSX: CPX) (“Capital Power”). The Transaction values the North Carolina Assets at approximately Cdn$121 million. This Transaction will have the effect of reducing the number of CPILP units outstanding by approximately 6.2 million units.
