Successful Completion and Opening of Northern Diabolo Project

7 June 2012

International Public Partnerships ("INPP" or "the Company"), the FTSE 250 listed infrastructure investment company which invests in global public infrastructure projects developed under the public private partnerships (PPP), private finance initiative (PFI) and other similar procurement methods, today announces the official opening of the Northern Diabolo Project, the Company's largest asset.

The Belgium based project, which will provide greater rail access to Brussels airport is being opened today by King Albert II of Belgium. The five year project included the construction of a new tunnelled rail connection under the airport runway to link the airport to the new Brussels - Antwerp High Speed rail line.

Financial close was reached on the project in September 2007, and construction work finished on time and on budget on 25 February 2012. INPP's concession term lasts for 35 years.

Northern Diabolo Project is INPP's largest asset, representing approximately 12% of INPP's Net Asset Value (NAV). INPP holds a 75% stake in the Northern Diabolo Project, with consortium partners HSH Nordbank, via its investment company Feronia GmbH, holding the remaining (25%).

In common with other assets owned by INPP, the value of INPP's investment in the Diabolo project may (other factors being equal) be reviewed provided that the transition from the construction phase to the operational phase of the project continues to progress smoothly. To the extent they materialise, any such valuation effects can be expected to be realised over the next 12 to 18 months.

Following completion of the Diabolo construction works the portion of the INPP portfolio remaining in the construction phase reduces from approximately 24% to approximately 12%.

INPP is delighted to recognise the contribution made to the project by Infrabel (its Belgian state-owned client).

INPP is currently conducting an Open Offer, Offer for Subscription and Placing targeting the raising of a further £180m of capital to invest in a pipeline of further investments of which more details can be found in the prospectus available from the Company's website at www.internationalpublicpartnerships.com or in the National Storage Mechanism of the Financial Services Authority at www.morningstar.co.uk/uk/NSM (the "Prospectus")

Keith Dorrian, Chairman of International Public Partnerships commented; "We're delighted to have reached this significant milestone on one of our flagship assets. Northern Diabolo will greatly enhance the road and rail access to and from Brussels Airport and benefit thousands of international and local users every year. The hard work and commitment shown by the international consortium and government partners has enabled the project to be delivered smoothly and we look forward to operating the asset for the next thirty plus years."
