To holders of Ordinary Shares in the Company ("Shareholders")

Dear Shareholder,

CIRCULAR TO SHAREHOLDERS AND NOTICE OF EXTRAORDINARY GENERAL MEETING

Introduction

As a matter of good corporate governance, the Board is seeking the approval of Shareholders for the proposed acquisition (the "Acquisition") of an interest in the AquaSure Victorian Desalination PPP Project near Melbourne in the State of Victoria, Australia (the "AquaSure Project") from the InfraRed Environmental Infrastructure Fund, a fund also managed by InfraRed Capital Partners Limited (the "Investment Adviser"), the Company's investment adviser.

Consequently, the Board is convening an extraordinary general meeting (the "EGM") for 3:30p.m. on 15 April 2014 in order to put an ordinary resolution approving the Acquisition to Shareholders ("Resolution"). The purpose of this Circular is to explain the background to, and reasons for, the Acquisition. Notice of the EGM is set out at the end of this Circular.

The Acquisition

Introduction

The Company continues to seek new investments which will allow for the development and diversification of its portfolio and has identified the AquaSure Project as being a suitable addition to the Company's portfolio. It is proposed that the Company will purchase a 5.85 per cent. equity interest in the AquaSure Project for consideration of approximately AUD\$84.5million. The Company has agreed in principle the key commercial terms of the Acquisition and, subject to signing a sale and purchase agreement with the seller and the satisfaction of certain other completion conditions, it is anticipated that the Acquisition will be completed by June 2014.

The AquaSure Project is currently part of a portfolio of investments held by the InfraRed Environmental Infrastructure Fund, a fund managed by the Company's Investment Adviser. While the Acquisition would not constitute a related party transaction for the purposes of the Financial Conduct Authority's Listing Rules, the Board has concluded that this connection to the Investment Adviser makes it appropriate, in the interests of sound corporate governance, to seek the prior approval of Shareholders for the Acquisition at the EGM.

Further details of the AquaSure Project and the "rules of engagement" that have been implemented to manage the potential conflicts of interest are set out below.

Information on the AquaSure Project

The AquaSure Project was procured under the State of Victoria's Partnerships Victoria Policy and is the largest desalination plant in the southern hemisphere capable of producing 444ML of drinking water per day (150GL/year). The AquaSure Project reached financial close in September 2009 and became fully operational in December 2012. The term of the AquaSure Project ends on 30 September 2039.

Construction of the AquaSure Project was undertaken by a construction joint venture of Theiss Pty Ltd and Degrémont Pty Ltd. It is now being operated and maintained by an operations joint venture of Degrémont Pty Ltd and Theiss Services Pty Ltd. The total construction cost was approximately AUD\$3.5 billion. The AquaSure Project is being managed by a directly employed management team of ten.

Rules of Engagement

Since the launch of the Company in 2006, it has been anticipated that some of the Company's investments will be investments that have been originated and developed by the Investment Adviser, and may be acquired from the Investment Adviser or any other funds managed by the Investment Adviser.

In order to manage conflicts of interest, detailed procedures have been established for transactions between the Company, the Investment Adviser and funds managed by the Investment Adviser. The Board has ensured that these procedures, which form part of the Company's stated investment policy, were adopted in connection with the proposed Acquisition. In particular:

• The Investment Adviser established a "buyside" committee and a "sellside" committee to consider the terms of the Acquisition and information barriers were put in place between each committee.
• The "buyside" committee has conducted an independent due diligence process on the AquaSure Project and the Board commissioned an independent third party to prepare a report on the fair market value for the Acquisition. This is the same party that gives the Directors of the Company an independent valuation validation every six months when the Directors publish their valuation of the Company's portfolio.

The Board has had the opportunity to ask questions of the "buyside" committee and to review the fair market value report prepared by the independent expert prior to the terms of the Acquisition being agreed, to ensure that it is satisfied that they have been negotiated on an arm's length basis.

Risks relating to the Acquisition

As the Acquisition falls within the Company's investment policy, the types of risks attributable to the AquaSure Project are consistent with the types of risks attributable to other projects in the Company's investment portfolio.

Action to be taken

Shareholders will receive a Form of Proxy for use by Shareholders at the EGM. Whether or not you propose to attend the EGM in person, you are requested either to complete the Form of Proxy and return it to PXS 1, 34 Beckenham Road, Beckenham, Kent BR3 4ZF in accordance with the instructions printed on it, or, if you hold your Ordinary Shares in CREST, to utilise the CREST electronic proxy appointment service in accordance with the procedures set out on the Form of Proxy. In each case, proxy votes should be returned as soon as possible, but in any event not later than 48 hours before the time appointed for the EGM or any adjournment of that meeting. Completion and return of Forms of Proxy will not prevent you from attending and voting in person at the EGM should you wish to do so. All Shareholders are entitled to attend, speak and vote at the EGM and to appoint a proxy or corporate representative to exercise that right.

If you have a query concerning this document or the EGM, please telephone Capita Asset Services between 9.00 a.m. and 5.00 p.m. (London time) Monday to Friday on 0871 6640300 from within the UK or +44 20 8639 3399 if calling from outside the UK. Calls to the 0871 6640300 number cost 10 pence per minute from a BT landline (other network providers' costs may vary). Calls to this line from outside the UK will be charged at applicable international rates. Different charges may apply to calls from mobile telephones and calls may be recorded and randomly monitored for security and training purposes. The helpline cannot give any financial, legal or tax advice.

Recommendation

The Board believes that the Acquisition is in the best interests of the Company and Shareholders as a whole and unanimously recommends that Shareholders vote in favour of the Resolution, as all of the Directors intend to do in respect of their own beneficial holdings of Ordinary Shares which amount in aggregate to 756,670 Ordinary Shares (representing approximately 0.06 per cent. of the existing issued ordinary share capital of the Company).

Yours sincerely,

Graham Picken Chairman

Notes:

• 1.A member of the Company who is entitled to attend, speak and vote at the Extraordinary General Meeting is entitled to appoint one or more proxies to attend, speak and on a poll or otherwise to vote in his or her place. A proxy does not need to be a member of the Company but must attend the meeting to represent you. Details of how to appoint the Chairman of the meeting or another person as your proxy using the proxy form are set out in the notes to the proxy form. If you wish your proxy to speak on your behalf at the meeting you will need to appoint your own choice of proxy (not the Chairman) and give your instructions directly to them.
• 2.Shareholders will have received, or will shortly receive, a form of proxy which should be completed in accordance with the instructions. To be valid, the form of proxy (together with the power of attorney or other authority (if any) under which it is signed or a notarially certified copy of such authority) must be deposited with the Company's UK Transfer Agent, PXS 1, 34 Beckenham Road, Beckenham, Kent BR3 4ZF not later than 48 hours before the time appointed for the Extraordinary General Meeting or any adjournment of that meeting at which the person named in the instrument proposes to vote. Completion of the form of proxy will not preclude a member from attending and voting in person.
• 3.To change your proxy instructions simply submit a new proxy form using the methods set out above and in the notes to the proxy form. Note that the cut-off date and time for receipt of a proxy form (see above) do not apply in relation to amended instructions given to a proxy validly appointed prior to the relevant cut-off date. If you submit more than one valid proxy form, the form received last before the latest time for the receipt of proxies will take precedence.
• 4.In order to revoke a proxy instruction you will need to inform the Company by sending a signed hard copy notice clearly stating your intention to revoke your proxy appointment to Company's UK Transfer Agent. In the case of a member which is an individual, the revocation notice must be under the hand of the appointer or of his attorney duly authorised in writing or, in the case of a member which is a company, the revocation notice must be executed under its common seal or under the hand of an officer of the company or an attorney duly authorised. Any power of attorney or any other authority under which the revocation notice is signed (or a notarially certified copy of such power or authority) must be included with the revocation notice.
• 5.The revocation notice must be received by the commencement of the Extraordinary General Meeting or any adjournment of that meeting. If you attempt to revoke your proxy appointment but the revocation is received after the time specified then, subject to the paragraph directly below, your proxy appointment will remain valid.
• 6.Appointment of a proxy does not preclude you from attending the meeting and voting in person. If you have appointed a proxy and attend the meeting in person, your proxy appointment will automatically be terminated.

Additional Notes:

CREST members who wish to appoint a proxy or proxies by utilising the CREST electronic proxy appointment service may do so for the Extraordinary General Meeting to be held at 3:30p.m.. on 15 April 2014 and any adjournment(s) thereof by utilising the procedures described in the CREST Manual. CREST Personal Members or other CREST sponsored members, and those CREST members who have appointed a voting service provider(s), should refer to their CREST sponsor or voting service provider(s), who will be able to take the appropriate action on their behalf.

In order for a proxy appointment made by means of CREST to be valid, the appropriate CREST message (a "CREST Proxy Instruction") must be properly authenticated in accordance with Euroclear UK & Ireland Limited's specifications and must contain the information required for such instructions, as described in the CREST Manual. The message must be transmitted so as to be received by the issuer's agent (RA10) by the latest time for receipt of proxy appointments specified in this notice of meeting. For this purpose, the time of receipt will be taken to be the time (as determined by the timestamp applied to the message by the CREST Applications Host) from which the issuer's agent is able to retrieve the message by enquiry to CREST in the manner prescribed by CREST.

CREST members and, where applicable, their CREST sponsors or voting service providers should note that Euroclear UK & Ireland Limited does not make available special procedures in CREST for any particular messages. Normal system timings and limitations will therefore apply in relation to the input of CREST Proxy Instructions. It is the responsibility of the CREST member concerned to take (or, if the CREST member is a CREST personal member or sponsored member or has appointed a voting service provider(s), to procure that his CREST sponsor or voting service provider(s) take(s)) such action as shall be necessary to ensure that a message is transmitted by means of the CREST system by any particular time. In this connection, CREST members and, where applicable, their CREST sponsors or voting service providers are referred, in particular, to those sections of the CREST Manual concerning practical limitations of the CREST system and timings. The Company may treat as invalid a CREST Proxy Instruction in the circumstances set out in Regulation 35(5)(a) of the Uncertificated Securities Regulations 2001.
