Dear shareholder,

Annual General Meeting

1. Introduction

The Annual General Meeting of the Company will be held at 16 Palace Street, London SW1E 5JD on Tuesday 8 July 2014 at 11.00am. The business to be considered at the Annual General Meeting is contained in the formal notice convening the Annual General Meeting on pages 5 and 6 of this document. A brief explanation of each resolution to be considered is set out below.

Voting on all of the proposed resolutions at the Annual General Meeting will, again, be conducted on a poll rather than a show of hands. Voting on a poll is seen as best practice as it gives all shareholders the same opportunity to participate in company decisions and have their votes recorded.

2. Resolutions at the Annual General Meeting

Resolution 1: The Directors are required to lay the Company's accounts and the auditors' report before the members at a general meeting. A copy of the Company's accounts for the financial year ended 31 March 2014 (the "2014 Accounts") is enclosed (except for those shareholders who have previously consented to receive e-communications only).

Resolution 2: Listed companies incorporated in the UK are required to prepare a Directors' remuneration report and put a resolution to approve the report to the shareholders at the Annual General Meeting. Although 3i Infrastructure plc is incorporated in Jersey, and has only non-executive Directors, the Board has chosen to ask shareholders to approve the Directors' remuneration report, a copy of which is set out on page 61 of the 2014 Accounts. The vote on the remuneration report is advisory in nature, meaning that payments already made to Directors will not have to be repaid in the event that the resolution is not passed. However, in respect of the proposed increase to the additional fee paid to the Senior Independent Director, this increase will not be implemented unless Resolution 2 is passed.

Resolution 3: The Directors are pleased to recommend, and the shareholders are requested to declare, a final dividend of 3.35p per Ordinary Share, payable to those shareholders whose names appear on the Register of Members at close of business on 20 June 2014. If the final dividend is approved, it is proposed to be paid on 11 July 2014.

Resolutions 4, 5, 6, 7, 8 and 9: The Company's Articles of Association contain provisions for the periodic retirement of Directors. However, in accordance with current best practice in the UK Corporate Governance Code, the Board has decided that all Directors wishing to serve as Directors for the forthcoming year stand for election or re-election (as appropriate) as Directors at this Annual General Meeting. Each Director elected or re-elected (as appropriate) will hold office until he or she retires, or otherwise ceases to be a Director in accordance with the Company's Articles of Association or by operation of law, or until he or she resigns.

The UK Corporate Governance Code recommends that the Board should undertake a formal annual evaluation of its own performance and that of its committees and individual Directors. During the year, the Board conducted its annual evaluation of its own performance and effectiveness and that of its committees and individual Directors. All Board members gave personal views to me in my role as Chairman and I gave feedback to the Board. These processes also involved evaluation by members of the Audit Committee of their performance. The Senior Independent Director also led a review by the Directors of my performance as Chairman.

The Board's policy is to refresh its composition through time in a planned way that provides it with the desired skill set. Two new directors have joined the Board in the last year, and it is expected that new directors will join over the coming year. In line with the Company's policy on diversity, the Company will continue to search for a suitable female candidate as part of those appointments.

Following the review process of all Directors, and in accordance with Section B.7.2 of the UK Corporate Governance Code, I will propose their election or re-election, as appropriate, at the forthcoming Annual General Meeting. The Board believes that each Director standing for election or re-election (as appropriate) should be elected or re-elected (as appropriate), as each has an appropriate level of experience in the infrastructure market or in management of investment vehicles similar to the Company. The Board further believes that each Director's performance continues to be effective and demonstrates commitment to their respective roles.

3i Infrastructure plc Notice of Annual General Meeting 2014 03

Part I continued

Brief details of those Directors seeking shareholder approval for election or re-election (as appropriate) are set out below.

Peter Sedgwick

Between 2000 and 2006, Peter was a member of the management committee and a Vice President of the European Investment Bank ("EIB"), one of the largest multinational lending institutions in the world. He was also a director of the European Investment Fund from 2002 to 2006. Before joining the EIB, he was a career HM Treasury civil servant in the UK.

Philip Austin

Philip has spent most of his career in banking with HSBC in the UK and Jersey and, from 1997 to 2001, was Deputy Chief Executive of the bank's business in the Offshore Islands. In 2001, he became the founding CEO of Jersey Finance Ltd, the body set up as a joint venture between the Government of Jersey and its Finance Industry, to represent and promote the Industry in Jersey and internationally. Between 2006 and 2009, he was at Equity Trust where he had direct responsibility for Jersey, Guernsey and Switzerland as well as being a member of the Group Executive Committee. He has since taken a number of directorships in companies in the financial services sector. He is a Fellow of the Chartered Institute of Bankers and a Fellow of the Institute of Management. He is resident in Jersey.

Sir John Collins

Sir John Collins was previously Chairman of DSG International plc, National Power Limited, and Shell UK plc. He was a non-executive director of Rothschild Continuation Holdings AG and The Peninsular and Oriental Steam Navigation Company plc. He has also served as Chairman of the Advisory Committee on Business and the Environment, Chairman of the DTI's Energy Advisory Panel, Chairman of the DTI/DEFRA's Sustainable Energy Policy Advisory Board, President of the Energy Institute and as a Governor of Wellington College. He is resident in Guernsey.

Paul Masterton

Paul spent most of his career in the printing and communications industry, holding various appointments in the UK, the US and Asia. From 2008 to 2013 Paul was the chief executive of the Durrell Wildlife Conservation Trust, an international wildlife charity. Paul has a number of directorships in banking, insurance and property development and, in 2012, was appointed as the founding chairman for Digital Jersey, a partnership between the Government of Jersey and the digital sector to represent and promote the industry. He is resident in Jersey.

Steven Wilderspin

Steven has been the Principal of Wilderspin Independent Governance, which provides independent directorship services, since April 2007. He was previously a director of fund administrator Maples Finance Jersey Limited. He has served on a number of private equity, property and hedge fund boards as well as the boards of special purpose companies engaged in structured finance transactions. Before that, from 1997, he acted as Head of Accounting at Perpetual Fund Management (Jersey) Limited. He is a qualified Chartered Accountant. He is resident in Jersey.

Ian Lobley

Ian is standing for election to the Board of the Company for the first time. Ian joined 3i Group in 1987 and has been a Partner since 1994. In his current role, Ian has responsibility for investments in companies across a variety of sectors and is an experienced board member across multiple geographies. Ian is a member of the 3i Group Investment Committee and of the BVCA UK and European Capital Committee and is the 3i Group nominee to the Company's Board. He is resident in the UK.

Resolutions 10 and 11: Shareholders will be asked to confirm the re-appointment of Ernst & Young LLP as the Company's auditors until the conclusion of the next annual general meeting due to be held in 2015 and to grant authority to the Board to determine their remuneration.

Resolution 12: This resolution gives the Board the authority, in accordance with Article 115 of the Company's Articles of Association, to offer the holders of Ordinary Shares of the Company, to the extent and in the manner determined by the Directors, the right to elect to receive new Ordinary Shares (credited as fully paid) instead of cash, in respect of all or part of any dividend declared or paid in the period between the passing of this resolution and conclusion of the annual general meeting of the Company due to be held in 2015 (the "Scrip Dividend Scheme").

Resolution 13: This resolution gives the Board the authority, in accordance with the Company's Articles of Association, to capitalise the appropriate nominal amounts of new Ordinary Shares of the Company to be allotted pursuant to any elections under the Scrip Dividend Scheme out of the sums standing to the credit of any reserve or account of the Company, to apply such sum in paying up such Ordinary Shares in the Company in full and to allot such Ordinary Shares to the shareholders of the Company making such elections.

Resolution 14: For legal, regulatory and practical reasons there may be occasions when the Directors will need the flexibility to issue shares without a pre-emptive offer to existing shareholders. This resolution gives the Board authority to allot equity securities (being Ordinary Shares or rights to subscribe for, or to convert securities into, Ordinary Shares) for cash without first offering them to existing shareholders on a pro-rata basis. The limit on the number of equity securities which may be so allotted is equity securities representing 5% of the issued ordinary share capital of the Company as at 28 May 2014 (representing 44,067,578 Ordinary Shares). The authority expires at close of business on the date falling 15 months after the date of passing of this resolution or the conclusion of the next annual general meeting of the Company, whichever is the earlier.

As at the date hereof, the Directors have no intention to exercise this authority, although they consider its grant to be appropriate in order to preserve maximum flexibility for the future. The Directors intend to comply with the Pre-Emption Group's Statement of Principles in relation to the cumulative three year cap regarding non-pre-emptive issues for cash.

This resolution is to be passed as a special resolution under Jersey law and so would require a majority of not less than 66%. However, under the Company's Articles of Association, this resolution requires a majority of 75%.

3i Infrastructure plc Notice of Annual General Meeting 2014

Part I continued

Resolution 15: This resolution renews the share buy-back authority that was given at the annual general meeting of the Company last year. Resolution 15 gives the Directors authority to make market purchases of the Company's own shares for cancellation, up to 14.99% of the Company's issued share capital as at 28 May 2014 (representing 132,114,600 Ordinary Shares). This authority will only be invoked if, after taking proper advice, the Directors consider that benefits will accrue to shareholders generally, either through enhancement of the Net Asset Value (NAV) per share or gauged by another measure deemed to be more relevant.

The resolution specifies the maximum and minimum prices at which shares may be bought. Any shares purchased in this way will be cancelled (and the number of shares in issue reduced accordingly). Given that the Company's shares do not have a nominal value, the Board has decided to provide for the minimum price in the buy-back resolution to be calculated by reference to market value, in order to mirror more closely the spread between minimum and maximum price of other listed companies that use the nominal value of their shares as their minimum price. The authority expires at close of business on the date falling 15 months after the date of passing of this resolution or the conclusion of the next annual general meeting of the Company, whichever is the earlier.

As at the date hereof, the Directors have no intention to exercise this authority, although they consider its grant to be appropriate in order to preserve maximum flexibility for the future.

There are no warrants to subscribe for equity shares outstanding as at 28 May 2014, as unexercised warrants expired on 13 March 2012. Resolution 15 is to be passed as a special resolution under Jersey law and so requires a majority of not less than 66%.

3. Action to be taken

You will find accompanying this document a Proxy Form for use in relation to the Annual General Meeting. Alternatively, you may register the appointment of a proxy for the Annual General Meeting by accessing the website www.capitashareportal.com or through the CREST electronic voting system. Guidance notes to assist you to complete the Proxy Form or to register the appointment of a proxy electronically are set out on pages 7 and 8 of this document.

Whether or not you intend to be present at the Annual General Meeting, you are requested to complete and sign the accompanying Proxy Form in accordance with the instructions printed thereon or to register the appointment of a proxy electronically. You are requested to return a completed Proxy Form to Capita Asset Services at PXS, 34 Beckenham Road, Beckenham, Kent BR3 4TU, or make your electronic proxy appointment by no later than 11.00am on Sunday 6 July 2014. The completion and return of the Proxy Form or the appointment of a proxy electronically will not prevent you from attending the Annual General Meeting and voting in person if you so wish and are so entitled.

If you have any questions relating to the completion and return of the Proxy Form, please telephone Capita Asset Services (Tel: 0871 664 0300 or, if calling from outside the UK, +44 20 8639 3399; calls made from a landline in the UK cost 10p per minute plus network extras). Please note that calls to these numbers may be monitored or recorded for quality and training purposes.

4. Recommendation

The Board considers that the resolutions proposed in this notice of Annual General Meeting are in the best interests of the Company and the shareholders as a whole. Accordingly, the members of the Board (other than, in the case of Resolutions 4 to 9, the Director proposed for election or re-election (as appropriate) in each resolution) unanimously recommend shareholders to vote in favour of the resolutions to be proposed at the Annual General Meeting, as all the Directors intend to do in respect of their own beneficial holdings totalling 143,868 Ordinary Shares (representing approximately 0.016% of the Company's issued share capital) as at 28 May 2014, being the latest practicable date prior to the publication of this document.

Yours sincerely,

P. N. Sedgwick

Peter Sedgwick
Chairman

Part III

Guidance notes for completion of the Proxy Form and Electronic Proxy Voting

1. Shareholders entitled to attend and vote at the Annual General Meeting are entitled to appoint one or more proxies to attend, speak, and, on a poll, to vote in their place. If you wish to appoint a proxy please use the Proxy Form enclosed with this document or the Electronic Proxy Voting systems described in paragraphs 2 and 3 below. In the case of joint shareholders, only one need sign the Proxy Form. The vote of the senior joint shareholder will be accepted to the exclusion of the votes of the other joint shareholders. For this purpose, seniority will be determined by the order in which the names of the shareholders appear in the register of members in respect of the joint shareholding. The completion and return of the Proxy Form will not stop you from attending and voting in person at the Annual General Meeting should you wish to do so and are so entitled. A proxy need not be a shareholder of the Company. You may appoint more than one proxy provided each proxy is appointed to exercise the rights attached to a different share or shares held by you.

To appoint more than one proxy you may photocopy the Proxy Form. Please indicate the proxy holder's name and number of shares in relation to which they are authorised to act as your proxy (which, in aggregate, should not exceed the number of shares held by you). Please also indicate if the proxy instruction is one of the multiple instructions being given. All forms must be signed and should be returned together in the same envelope.

1. Alternatively, shareholders are given the option to register the appointment of a proxy for the Annual General Meeting electronically by accessing the website www.capitashareportal.com. This website is operated by the Company's registrar, Capita Asset Services. Full details of the proxy voting procedure are given on the website and shareholders are advised to read the terms and conditions relating to the use of this facility before appointing a proxy. Electronic communication facilities are available to all shareholders and those who use them will not be disadvantaged in any way. Electronic proxy voting instructions are requested to be submitted using the website www.capitashareportal.com by no later than 11.00am on Sunday 6 July 2014. Any electronic communication sent by a shareholder that is suspected to contain a computer virus will not be accepted.

2. CREST members who wish to appoint a proxy or proxies through the CREST electronic proxy appointment service may do so for the Annual General Meeting to be held on Tuesday 8 July 2014 and any adjournment(s) thereof by using 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, should refer to their CREST sponsor or voting service provider, who will be able to take the appropriate action on their behalf.

In order for a proxy appointment or instruction made using the CREST service to be valid, the appropriate CREST message (a CREST Proxy Instruction) must be properly authenticated in accordance with CRESTCo's specifications and must contain the information required for such instructions, as described in the CREST Manual. The message, regardless of whether it constitutes the appointment of a proxy or an amendment to the instruction given to a previously appointed proxy, must, in order to be valid, be transmitted so as to be received by the issuer's agent (RA10) by the latest time for receipt of proxy appointments specified in the 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. After this time, any change of instructions to proxies appointed through CREST should be communicated to the appointee through other means.

CREST members and, where applicable, their CREST sponsors or voting service providers should note that CRESTCo 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, to procure that his CREST sponsor or voting service provider takes) 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 Articles 33-34 of the Companies (Uncertificated Securities) (Jersey) Order 1999. All messages relating to the appointment of a proxy or an instruction to a previously appointed proxy, which are to be transmitted through CREST, are required to be lodged no later than 11.00am on Sunday 6 July 2014.

1. You can appoint the Chairman of the Meeting, or any other person, as your proxy. If you wish to appoint someone other than the Chairman, cross out the words "the Chairman of the meeting" on the Proxy Form and insert the full name and address of your appointee.

2. You can instruct your proxy how to vote on each resolution on which a poll is taken by ticking the "For" or "Against" boxes as appropriate (or entering the number of shares which you are entitled to vote). If you wish to abstain from voting on any resolution on which a poll is taken please tick the box which is marked "Vote Withheld". It should be noted that a vote withheld is not a vote in law and will not be counted in the calculation of the proportion of the votes "For" and "Against" a resolution. If you do not indicate on the Proxy Form how your proxy should vote, he/she can exercise his/her discretion as to whether, and if so how, he/she votes on each resolution, as he/she will do in respect of any other business (including amendments to resolutions) which may properly be conducted at the Annual General Meeting.

3. A company incorporated in England & Wales or Northern Ireland should execute the Proxy Form under its common seal or otherwise in accordance with Section 44 of the Companies Act 2006 or by signature on its behalf by a duly authorised officer or attorney whose power of attorney or other authority should be enclosed with the Proxy Form.
