Certain of the statements contained in this news release are forward-looking and reflect management’s expectations regarding the Fund’s future growth, results of operations, performance and business based on information currently available to the Fund. Forwardlooking statements are provided for the purpose of presenting information about management's current expectations and plans relating to the future and readers are cautioned that such statements may not be appropriate for other purposes. These statements use forward-looking words, such as “anticipate”, “continue”, “could”, “expect”, “may”, “will”, “estimate”, “believe” or other similar words, and include, among other things, statements relating to the Fund’s conversion to a dividend-paying corporation (the “Conversion”), the Fund’s distributions and distribution policy; and the anticipated dividend policy of Macquarie Power and Infrastructure Corporation (“MPIC”).

The forward-looking statements in this news release are based on information currently available and what the Fund currently believes are reasonable assumptions, including the material assumptions for each of the Fund’s assets set out in the Fund’s 2009 Annual Report under the heading “Outlook” on page 42, as updated in subsequently filed Quarterly Financial Reports of the Fund (such documents are available on the Canadian Securities Administrators’ System for Electronic Document Analysis and Retrieval (“SEDAR”) at www.sedar.com). Other material factors or assumptions that were applied in formulating the forward-looking statements contained herein include the assumption that the business and economic conditions affecting the Fund’s operations will continue substantially in their current state, including, with respect to industry conditions, general levels of economic activity, regulations, weather, taxes and interest rates and that there will be no unplanned material changes to the Fund’s facilities, equipment or contractual arrangements.

Although the Fund believes that it has a reasonable basis for the expectations reflected in these forward-looking statements, actual results may differ from those suggested by the forward-looking statements for various reasons, including risks related to: power infrastructure (operational performance; power purchase agreements; fuel costs and supply; contract performance; development risk; technology risk; default under credit agreements; land tenure and related rights; regulatory regime and permits; environmental, health and safety; climate change and the environment; force majeure; the Fund (changes in federal tax rules for flow-through entities; other tax-related risks; variability of distributions; geographic concentration and non-diversification; dependence on Macquarie Power Management Ltd. (“MPML” or the “Manager”) and potential conflicts of interest; insurance; environmental, health and safety regime; availability of financing; unitholder dilution; volatile market price for units; international financial reporting standards; nature of units; unitholder liability). There are also a number of risks related to the Fund’s Plan of Arrangement (the “Arrangement”) providing for the conversion and to the activities of MPIC or the ownership of MPIC common shares, including risks relating to: changes to the Arrangement structure; the assessment of fair market value of the Fund units and MPIC common shares; the satisfaction of conditions precedent to the Arrangement; the receipt of regulatory approvals affecting the Arrangement; the realization of the anticipated benefits of the Arrangement; the impact on the Fund’s unit price and future business operations of the Fund should the Arrangement not be completed; dilution of MPIC shareholders; the payment of dividends by MPIC, which are not guaranteed; and unpredictability and volatility of the common share price of MPIC.

For a more comprehensive description of these and other possible risks, please see the Fund’s Annual Information Form dated March 25, 2010 for the year ended December 31, 2009 as updated in subsequently filed Quarterly Financial Reports and other filings of the Fund with the Canadian securities regulators.
