Macquarie Power & Infrastructure Income Fund to Provide Additional Time for Confirmation of Residency by Non-Tendering Clean Power Income Fund Unitholders

TORONTO, ONTARIO (June 28, 2007) – Following the successful completion of its acquisition of Clean Power Income Fund (“CPIF”) on June 26, 2007, Macquarie Power & Infrastructure Income Fund (TSX: MPT.UN – “MPT” or the “Fund”) today announced that the Canadian Depositary for Securities (“CDS”) has agreed to extend the period during which former holders of units (“CPIF Units”) of CPIF who did not tender their units to MPT’s offer to purchase dated May 18, 2007 (the “Offer”) may provide confirmation of their Canadian residency.

As described below, any non-tendering CPIF Unitholder who is a resident of Canada and who wishes to receive MPT Units (rather than the net proceeds of the sale thereof as contemplated below) and CVRs is advised to contact such person’s broker or investment dealer in sufficient time to permit such broker or investment dealer to confirm the Canadian residency of such person to MPT and the depositary prior to 4 p.m. (Toronto time) on Friday, June 29, 2007.

Former CPIF Unitholders who tendered their CPIF Units under the Offer and who are residents of Canada do not need to take any further action. As described in MPT’s take-over bid circular dated May 18, 2007 (the “Circular”), each such person was issued 0.5581 of a trust unit (a “MPT Unit”) and one contingency value receipt (“CVR”) of MPT for each CPIF Unit tendered.

On June 26, 2007, MPT completed both the Offer and the subsequent acquisition transaction described in its Circular. Pursuant to the subsequent acquisition transaction, all but one of the 35,847,828 issued and outstanding CPIF Units were redeemed in exchange for a redemption price equal in value to, and in the same form as, the consideration offered under the Offer. The sole remaining issued and outstanding CPIF Unit is held by MPT. For each CPIF Unit redeemed pursuant to the subsequent acquisition transaction, 0.5581 of a MPT Unit and one CVR (a “CVR”) was issued, as described in the Circular. As disclosed in the Circular, former CPIF Unitholders who are resident in jurisdictions outside of Canada are not entitled to receive MPT Units or CVRs in connection with MPT’s Offer or the subsequent acquisition transaction, unless it is established to the satisfaction of MPT, whose determination is final and binding, that the MPT Units and CVRs can be offered and delivered in the applicable non-Canadian jurisdiction on a basis acceptable to MPT in its sole discretion. All MPT Units otherwise payable to former CPIF Unitholders who are unable to satisfy MPT on such a basis will be sold through the facilities of the Toronto Stock Exchange, through a registered broker or investment dealer. Each former CPIF Unitholder whose MPT Units are to be sold in such a manner will be forwarded a payment in cash in an amount equal to such former CPIF Unitholder's pro rata interest in the net proceeds of such sale or sales, after commissions, expenses and any applicable withholding taxes, as soon as practicable after completion of such sale or sales. In effecting the sale of MPT Units as described above, the registered broker or investment dealer will exercise its sole judgment as to the timing and manner of any sale or sales and will not be obligated to seek or obtain a minimum price. The sale price of such MPT Units will fluctuate with the market price of the MPT Units and no assurance can be given that any particular amount will be received upon any such sale.

In addition, the CVRs otherwise distributable to such former CPIF Unitholders who are resident in jurisdictions outside of Canada will be issued to an escrow agent until payment, if any, on the CVRs is made, at which time each such former CPIF Unitholder will be forwarded a payment in cash in an amount equal to such former CPIF Unitholder's pro rata portion of the payment amount, if any, net of all costs related to such arrangements and any applicable withholding taxes.

Unless it is established prior to Friday, June 29, 2007 at 4 p.m. (Toronto time) to the satisfaction of MPT and the depositary under the Offer, whose determination shall be final and binding, that a former CPIF Unitholder is a resident of Canada, it will be assumed that such unitholder is a resident of a non-Canadian jurisdiction.

The request for confirmation of residency for Canadian resident former CPIF Unitholders prior to the completion of the subsequent acquisition transaction was previously communicated in a formal bulletin from CDS to all CDS intermediaries on June 19, 2007 and in a news release issued by MPT dated June 25, 2007.
