• 1. You will need to state clearly on each proxy form the number of shares in relation to which the proxy is appointed. A failure to specify the number of shares to which each proxy appointment relates or specifying a number of shares in excess of those held by the member will result in the proxy appointment being invalid.
• 1. The return of a completed proxy form or any CREST Proxy Instruction (as described in paragraph 11 below) will not prevent a shareholder attending the Annual General Meeting and voting in person if he/she wishes to do so.
• 1. In the case of joint holders, where more than one of the joint holders purports to appoint a proxy, only the appointment submitted by the most senior holder will be accepted. Seniority is determined by the order in which the names of the joint holders appear in the Company's Register of Members in respect of the joint holding (the first-named being the most senior).

Nominated Persons

• 1. Any person to whom this Notice is sent who is a person nominated under section 146 of the Companies Act 2006 to enjoy information rights (a "Nominated Person") may, under an agreement between him/her and the shareholder by whom he/she was nominated, have a right to be appointed (or to have someone else appointed) as a proxy for the Annual General Meeting. If a Nominated Person has no such proxy appointment right or does not wish to exercise it, he/she may, under any such agreement, have a right to give instructions to the shareholder as to the exercise of voting rights.
• 1. The statement of the rights of shareholders in relation to the appointment of proxies in paragraphs 1, 2 and 3 above does not apply to Nominated Persons.The rights described in those paragraphs can only be exercised by shareholders of the Company.

To be entitled to attend and vote at the Annual General Meeting (and for the purpose of the determination by the Company of the votes they may cast), shareholders must be registered in the Register of Members of the Company at 6.00 p.m. on 18 July 2017 (or, in the event of any adjournment, 6.00 p.m. on the date which is two days before the time of the adjourned meeting). Changes to the Register of Members after the relevant deadline shall be disregarded in determining the rights of any person to attend and vote at the meeting.

Total voting rights

1. As at 7 June 2017 (being the last practicable date prior to the publication of this Notice), the Company's issued share capital consists of 157,912,351 ordinary shares.

CREST members

• 1. 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 and any adjournment(s) of the meeting by using the procedures described in the CREST Manual(available via www.euroclear.com). CREST Personal Members or other CREST sponsored members, and those CREST members who have appointed a 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.
• 1. 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 Euroclear UK & Ireland Limited's specifications and must contain the information required for such instruction, as described in the CREST Manual.The message (regardless of whether it constitutes the appointment of a proxy or is 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 Company's agent(ID 3RA50) by the latest time for receipt of proxy appointments set out in paragraph 2 above. 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 Company's agent is able to retrieve the message by enquiry to CRESTin 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.
• 1. CREST members and, where applicable, their CREST sponsor or voting service providers should note that Euroclear UK & Ireland Limited does not make available special procedures in CRESTfor 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 any 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.

EXPLANATORY NOTES ON THE RESOLUTIONS TO THE NOTICE OF ANNUAL GENERAL MEETING

Resolutions 1 to 15 are ordinary resolutions. These resolutions will be passed if more than 50% of the votes cast for or against are in favour.

RESOLUTION 1: Report and Accounts

The Directors are required by the Companies Act 2006 to present to shareholders at a general meeting the Directors' Report and Accounts and the Auditors' Report for the year ended 31 March 2017.

RESOLUTION 2: Directors' Remuneration Report

Following changes to the Companies Act 2006 which took effect on 1 October 2013, the Directors' remuneration report is now divided into two parts:(i) a statement by the chairman of the Remuneration Committee, starting at page 70 of the Directors' Report and Accounts, and an annual report on remuneration, starting at page 75 of the Directors' Report and Accounts; and (ii)the Directors' remuneration policy, starting at page 72 of the Directors' Report and Accounts (together, the "Directors' Remuneration Report").

The Companies Act 2006 requires the Company to seek shareholder approval for the Directors' Remuneration Report(other than the part containing the Directors' remuneration policy) on an annual basis at the general meeting before which the Company's annual accounts are laid.This is sought in resolution 2.The vote on the Directors' Remuneration Report(other than the Directors' remuneration policy)is "advisory": that is, the Directors' entitlement to remuneration is not conditional on the report being approved.

The Companies Act requires the Company to seek shareholder approval of its Directors' remuneration policy at least every three years. Following its initial approval at the Company's annual general meeting in 2014, a revised policy was put to a shareholder vote at the annual general meeting in 2015.The Directors' remuneration policy is binding: after it takes effect, all payments to Directors by way of remuneration or for loss of office must be consistent with the Directors' remuneration policy (unless separately approved by a shareholder resolution). A remuneration policy will be put to shareholders again no later than the 2018 annual general meeting.

RESOLUTION 3: Declaration of Final Dividend

The Board are recommending a final dividend of 14.1 pence per ordinary share of which 10.5 pence will be a property income dividend ("PID"). Subject to approval by the shareholders, the final dividend will be paid on 27 July 2017 to shareholders on the register as at 6.00 p.m. on 23 June 2017.

RESOLUTIONS 4 to 12: Re-election of Directors

In accordance with the UK Corporate Governance Code, all of the Directors will stand for re election, including Vince Niblett who was appointed as a Director by resolution of the Board on 1 June 2017.

Each of the Directors (other than Vince Niblett) has undergone, during the year, a performance evaluation and has demonstrated that he or she remains committed to the role and continues to be an effective and valuable member of the Board of Directors. Biographical details of each of the Directors can be found in Appendix 1 to this Notice.

RESOLUTION 13: Appointment of Auditors

As explained in the annual report and accounts for the year ended 31 March 2016, in light of the new provision in the UK Corporate Governance Code regarding auditor rotation, the Audit Committee undertook a competitive tender process for the Company's external audit services during 2016. Given the regulatory changes, the Directors and Deloitte LLP mutually agreed that Deloitte LLP would not participate in the tender process.

Deloitte LLP will accordingly retire as the Company's auditor at the 2017 AGM. As required by section 519 of the Companies Act 2006, the retiring auditor has provided the following statement of reasons which the Company is required to distribute to members under section 520 of the Companies Act 2006. The statement was appended to Deloitte's letter of resignation dated 1 June 2017.

Statement of reasons relating to the intention of Deloitte LLP not to seek re-appointment as auditors to Big Yellow Group PLC at the conclusion of our term of office

We have tendered our resignation as auditors of Big Yellow Group PLC at the request of the Board.The Board put the audit out to tender but did not invite Deloitte LLP to participate.There are no matters that Deloitte considers need to be brought to the attention of members or creditors of the Company.

Deloitte LLP – Audit registration C009201919

1 June 2017

The Company is required to appoint auditors at each general meeting at which accounts are laid, to hold office until the conclusion of the next such meeting. Resolution 13 therefore proposes the appointment of KPMG LLP as the Company's auditor to hold office until the conclusion of the next annual general meeting of the Company.

RESOLUTION 14: Auditors' Remuneration

This resolution gives the Directors the authority to determine the remuneration of the auditors for the audit work to be carried out by them in the next financial year.The amount of the remuneration paid to the auditors for the next financial year will be disclosed in the next audited accounts of the Company.

RESOLUTION 15: Authority to the Directors to Allot Shares

Under the Companies Act 2006, the Directors may only allot shares if authorised to do so. If passed, this resolution will authorise the Directors to allot the Company's unissued shares up to a maximum nominal amount of £10,527,490.00 (up to 105,274,900 ordinary shares of 10 pence each), which is equal to approximately two-thirds of the issued ordinary share capital of the Company (excluding treasury shares) as at 7 June 2017, being the latest practicable date prior to the publication of the Notice.

As provided in paragraph (a) ofthe resolution, up to half ofthis authority (equalto approximately one-third ofthe issued ordinary share capital ofthe Company (excluding treasury shares)) will enable the Directors to allot and issue new shares in whatever mannerthey see fit. Paragraph (b) ofthe resolution provides thatthe remainder ofthe authority (equalto approximately a further one-third) may only be used in connection with a rights issue in favour of ordinary shareholders. As paragraph (a)imposes no restrictions on the way the authority may be exercised, it could be used in conjunction with paragraph (b) so as to enable the whole two-thirds authority to be used in connection with a rights issue.Where usage ofthis authority exceeds one-third ofthe issued share capital, the Directors intend to follow best practice as regards its use (including as to the requirementfor Directors to stand for re-election).

The authority will expire 15 months after the date of passing of the resolution or, if earlier, at the conclusion of the annual general meeting of the Company to be held in 2018.

Passing this resolution will ensure that the Directors continue to have the flexibility to act in the best interests of shareholders, when opportunities arise, by issuing new shares.The Directors currently have no intention of issuing new shares, except for the purposes of the Company's employee share schemes.

As at 7 June 2017, being the latest practicable date prior to the publication of the Notice, the Company did not hold any shares in treasury.

Resolutions 16, 17, 18 and 19 are special resolutions. These resolutions will be passed if not less than 75% of the votes cast for or against are in favour.

RESOLUTIONS 16 and 17 – Disapplication of Statutory Pre-emption Rights

The Companies Act 2006 prescribes certain pre-emption rights under which, ifthe Company issues new shares, or grants rights to subscribe for orto convert any security into shares, for cash or sells any treasury shares for cash, it mustfirst offerthem to existing shareholders in proportion to their current holdings.

Under Resolution 16, it is proposed that the directors be authorised to issue shares for cash and/or sell shares from treasury (if any are so held)for cash without offering them first to existing shareholders in proportion to their current holdings:

• (a) up to an aggregate nominal amount of £789,561.70 (up to 7,895,617 new ordinary shares of 10 pence each).This amount represents approximately 5% of the Company's issued share capital(excluding shares held in treasury) as at 7 June 2017, the latest practicable date prior to the publication of the notice.This part of the authority is designed to provide the board with flexibility to raise further equity funding and to pursue acquisition opportunities as and when they may arise; or
• (b) in respect of a rights issue, open offer or other offer that generally provides existing shareholders with the opportunity to subscribe for new shares pro rata to their existing holdings.This part of the authority is designed to give the directors flexibility to exclude certain shareholders from such an offer where the directors consider it necessary or desirable to do so in order to avoid legal, regulatory or practical problems that would otherwise arise.

Under Resolution 17, it is proposed that the directors be authorised to disapply statutory pre-emption rights in respect of an additional 5% of the Company's issued share capital(as at 7 June 2017, the latest practicable date prior to the publication of the notice, and excluding shares held in treasury). In accordance with the Pre-Emption Group's Principles, the directors confirm that this authority will be used only in connection with an acquisition or specified capital investment that is announced contemporaneously with the issue, or that has taken place in the preceding six-month period and is disclosed in the announcement of the issue.

If passed, the authorities in Resolution 16 and Resolution 17 will expire at the same time as the authority to allot shares given pursuant to Resolution 15.

Excluding any shares issued in connection with an acquisition or specified capital investment as described above, the directors do not intend to issue more than 7.5% of the issued share capital on a non-pre-emptive basis in any rolling three-year period.

RESOLUTION 18: Purchase of Own Shares by the Company

This resolution will grant the Company authority to buy its own shares in the market, subject to the constraints set out in the resolution.The resolution limits the number of shares that may be purchased to 10% of the issued share capital of the Company (excluding treasury shares) as at 7 June 2017, being the latest practicable date prior to the publication of the Notice.The resolution sets out the maximum and minimum prices that can be paid.

The Directors' current intention is that shares purchased pursuant to this authority (to the extent statutory requirements are met and provided any treasury shares held do not exceed 10% of the issued share capital of the Company) will be held in treasury for future cancellation, sale for cash or(provided Listing Rule requirements are met)transfer to an employee share scheme. However, shares repurchased by the Company may, in the light of the circumstances existing at the time of the repurchase, also be immediately cancelled.The effect of any cancellation would be to reduce the number of shares in issue. For most purposes, while held in treasury, shares are treated as if they had been cancelled (for example, they carry no voting rights and do not rank for dividends).The Directors will only make purchases under this authority if they believe to do so would result in an increase in earnings per share and would be in the interests of shareholders generally.

As at 7 June 2017, being the latest practicable date priorto the publication ofthe Notice, options were outstanding over 1,548,066 ordinary shares of 10 pence each in the Company representing approximately 0.98% ofthe issued share capital ofthe Company (excluding treasury shares) atthat date.
