(the 'Global Offer').

The Global Offer has raised gross proceeds of £700 million (prior to any

(at a price of £1 per ordinary share) and 70,000,000 warrants with a

Commenting on the Company's successful listing, Michael Queen, Managing Partner,
Head of Infrastructure, 3i, said:

'We are delighted with the successful completion of the largest IPO of an
infrastructure investment company in Europe. We are particularly pleased with
the quality of investors who have recognised the strength of 3i's infrastructure
proposition and who have invested despite the current turbulent equity market
conditions. 3i's Infrastructure team looks forward to delivering a quality
portfolio of global infrastructure assets.'

Also commenting on the amount raised in the Global Offer, Peter Sedgwick,
non-executive Chairman of the Company, said:

'The Board of Directors are delighted by the successful completion of the offer.
We look forward to working with the 3i Infrastructure team for the benefit of
the new shareholders.'

The Company intends to make equity (or equivalent) investments in infrastructure
businesses and assets, with an initial focus on Europe, North America and Asia.
It intends to invest the initial net proceeds of the Global Offer over the
two-year period following Admission.  3i Investments plc ('3i Investments'), a

Background

  • The Company will be advised on investment matters by 3i Investments,
    through its infrastructure investment team led by Michael Queen.

  • 3i Group is a leading European private equity and venture capital group
    with a specialist infrastructure investment team. 3i Group is listed on the
    London Stock Exchange and is a constituent of the FTSE 100 Index.   As at 30
    September 2006, 3i Group had £7 billion of assets under management. With
    over 300 investment professionals and offices in 14 countries worldwide, 3i
    Group has both local and global presence.

  • The Company will acquire an initial portfolio of UK infrastructure
    investments from 3i Group (the 'Initial Portfolio') for a purchase price
    proposed by 3i Group and accepted by the directors of the Company. The
    Company's independent valuation adviser has reported on the fairness and
    reasonableness of the proposed purchase price. The Initial Portfolio
    comprises an interest in substantially all of 3i Group's unrealised
    infrastructure investments:

     -  an investment in Anglian Water, the fourth largest water supply and
        waste water company in England and Wales, measured by regulatory capital 
        value, with approximately 4.2 million water and 5.4 million waste water 
        customers;

    -   an interest in Infrastructure Investments LP, one of the largest UK
        equity funds investing in secondary PFI projects; and

    -   investments in two other PFI projects:

        •  Norfolk and Norwich Hospital

        •  Alpha Schools, Scotland.

  • The Company intends to make investments with an overall objective of
    providing its shareholders with a total return (comprising the increase in
    net asset value, plus distributions, per share) of approximately 12% on the
    initial net proceeds of the Global Offer, to be achieved over the long-term.
    There can be no assurance that the Company will achieve its investment
    objective.  Within this overall objective, the Company will target an annual
    distribution yield of approximately 5% on the initial net proceeds of the
    Global Offer, once fully invested, through a combination of regular
    dividends and capital returns. Thereafter, the Company will target a
    progressive distribution policy (meaning that, if followed, the annual
    distributions would steadily increase in absolute terms over time).

  • The Company has an independent Board of non-executive directors consisting
    of Peter Wagner, Philip Austin, Martin Dryden and chaired by Peter Sedgwick.
    It is proposed that Paul Waller, a member of 3i Group's management
    committee, will also join the Board in due course.

  • Citigroup Global Markets Limited is acting as Sole Global Co-ordinator,
    Sponsor and Underwriter for the Global Offer.

  • The Company has granted to Citigroup, for stabilisation purposes, an
    over-allotment option in connection with the Global Offer (up to a maximum
    of 10% of the total number of ordinary shares and warrants comprised in the
    Global Offer), which may result in the issue of additional ordinary shares
    and warrants at the offer price.
