Clean Power Board Recommends Unitholders Accept Offer by Macquarie Power & Infrastructure Income Fund

  • Offer provides superior value for unitholders of Clean Power Income Fund
  • Expected by MPT to be accretive to unitholders in first year of combined operations

TORONTO, ONTARIO (April 18, 2007) – Macquarie Power & Infrastructure Income Fund (TSX: MPT.UN – “MPT” or the “Fund”) and Clean Power Income Fund (TSX: CLE.UN and CLE.DB) (“CPIF”) today announced that they have entered into a support agreement under which MPT has agreed to make an offer (the “Offer”) to acquire all of the outstanding units of CPIF. CPIF has agreed to support the Offer upon the terms and conditions set out in the MPT support agreement.

The Board of Trustees of Clean Power Operating Trust (“CPOT”), the sole beneficiary of which is CPIF, has unanimously approved the Offer and determined that the Offer is fair and in the best interests of CPIF and its unitholders. The Board of Trustees of CPOT has also received an opinion from its financial advisors that the consideration to be received under the Offer is fair, from a financial point of view, to CPIF unitholders, and has unanimously resolved to support MPT’s Offer. In addition, the Board of Trustees of CPOT has withdrawn its previous recommendation, no longer supports the offer previously announced by Algonquin Power Income Fund (“APIF”) and recommends that CPIF unitholders accept MPT’s Offer. CPIF unitholders that may have previously deposited their units under the APIF offer should withdraw their units by contacting their securities dealer or broker in order to tender to MPT’s Offer.

“Macquarie Power & Infrastructure Income Fund’s offer provides superior value for Clean Power unitholders as well as an opportunity to participate in a fund with a proven track record of stable performance, growth and value creation for unitholders,” said Mr. Gregory Smith, Chief Executive Officer of MPT. “We anticipate that this transaction will be accretive to distributions per unit in the first year of combined operations. In addition, the new MPT will have a significant platform to pursue further growth opportunities in the North American power infrastructure sector.”

Mr. Allen Jackson, Chairman of CPOT’s Board of Trustees, said, “MPT’s offer represents the best outcome from the continued investigation of unitholder value maximization opportunities subsequent to the APIF offer announced on February 26, 2007. The Board believes that the proposed transaction with MPT is in the best interest of CPIF unitholders and has agreed to support the MPT offer and recommend that CPIF unitholders accept the MPT offer over the previously announced APIF offer.”

As set out in the MPT support agreement, MPT has agreed to offer to CPIF unitholders 0.5581 MPT units and a contingency value receipt (“CVR”) for each unit of CPIF. Each CVR will entitle the holder, subject to certain conditions, to a payment in cash of an amount up to approximately $0.19 per CPIF unit; provided that if any refunds are received from Commonwealth Edison Co., the maximum amount payable under the CVR will increase. The CVRs will represent the right to receive an amount equal to 80% of the balance in the US$7.593 million reserve fund established by CPIF in connection with its sale of Gas Recovery Systems, LLC (“GRS”) together with any refunds received from Commonwealth Edison Co. relating to GRS after reduction for certain claims and costs and after specified adjustments.

Macquarie Power & Infrastructure Income Fund is not an authorised deposit taking institution for the purposes of the Banking Act (Cth) 1959 and Macquarie Power & Infrastructure Income Fund’s obligations do not represent deposits or other liabilities of Macquarie Bank Limited ABN 46 008 583 542. Macquarie Bank Limited does not guarantee or otherwise provide assurance in respect of the obligations of Macquarie Power & Infrastructure Income Fund.

A take-over bid circular containing the full terms of the Offer is expected to be mailed to CPIF’s unitholders and holders of its 6.75% convertible debentures, along with the circular of the Board of Trustees of CPOT and other related documents, in mid-May 2007. MPT’s Offer will be subject to customary closing conditions, including at least 66 2/3% of the outstanding CPIF units being validly deposited under the Offer and there not occurring any material adverse change in the business, facilities, operations, assets or liabilities of CPIF and its subsidiaries and affiliated entities.

MPT is not currently contemplating making an offer for CPIF’s outstanding 6.75% convertible debentures. However, if the Offer is successful, MPT is currently contemplating that a transaction would be undertaken that would result in these debentures becoming obligations of MPT.

The MPT support agreement also provides for, among other things, a non-solicitation covenant on the part of CPIF. In certain circumstances CPIF may terminate the support agreement and the Board of Trustees of CPOT may withdraw its recommendation to CPIF unitholders in accordance with the terms and conditions of the support agreement. In such circumstances, CPIF would be required to pay to MPT a termination fee of $7.0 million, plus up to $1.5 million in expenses.

The MPT support agreement allows CPIF to continue to declare and pay its regular monthly cash distributions to its unitholders and pay interest on its 6.75% convertible debentures, provided that all such payments are made in the normal course consistent with past practice and approved by the Board of Trustees of CPOT or the administrator of CPIF.

The execution of the MPT support agreement followed the announcement earlier today by APIF that it does not intend to exercise its right to match MPT’s previously announced proposal and the termination of the support agreement between APIF and CPIF in accordance with its terms. In connection with the termination of its support agreement, APIF is entitled to a termination fee of $1.75 million and reimbursement of its expenses to a maximum of $850,000 from CPIF.
