Part 3

Notes to resolutions

The following pages give an explanation of the proposed resolutions.

All resolutions will be proposed as ordinary resolutions, which means that, assuming a quorum is present, each such resolution will be approved if the number of votes cast in favour exceed the number of votes cast against such proposal.

Notes to Resolution 1 - Reports and accounts

The Board of Directors will present its reports and the accounts for the year ended 31 December 2016, which are contained in the Company's 2016 Annual Report, including the strategic report, the directors' report and the auditor's report, and the 20-F Form 2017. The 20-F Form was made public on 28 February 2017.

The Board recommends voting "For" this proposal.

Notes to Resolutions 2 and 3 – Directors' remuneration report and directors' remuneration policy

In accordance with The Large and Medium-sized Companies and Groups (Accounts and Reports) Regulations 2008, the directors' remuneration report in the Company’s 2016 Annual Report contains:

· a statement by Mr Jackson Robinson, Chair of the Company's Compensation Committee (“CC”);

· the annual report on remuneration, which sets out payments made in the financial year ended 31 December 2016; and

· the directors' remuneration policy in relation to future payments to the directors and former directors.

Shareholders will be invited to approve, by way of an advisory vote, the directors' remuneration report other than the directors' remuneration policy, which shareholders will be invited to approve by way of a binding vote.

The statement by the Chair of the CC and the annual report on remuneration can be found in the Company's 2016 Annual Report. The annual report on remuneration gives details of the directors' remuneration for the financial year ended 31 December 2016, and includes the directors' remuneration set out as single figures, including the Chief Executive Officer´s remuneration, and the directors' shareholdings in the Company.

Resolution 2 to approve these items is an advisory vote only and does not affect the actual remuneration paid to any director.

The Company auditors, Deloitte LLP, have audited those parts of the directors' remuneration report which are required to be audited and their report can be found in the Company's 2016 Annual Report. The report has been approved by the Board based on the recommendation of the CC and signed on its behalf by the Chief Executive Officer.

The Board recommends voting "For" this proposal.

Great West House, GW1, 17th Floor, Great West Road, Brentford TW8 9DF , London, UK, T + 44 203 547 8055 7

The directors' remuneration policy is set out in full in the 2016 Annual Report on pages 42 to 49. The directors' remuneration policy sets out the Company's proposed forward looking policy on directors' remuneration (including the approach to exit payments to directors), the Chief Executive Officer's remuneration and the management team and key personnel and employees' remuneration policy.

The principal change to the current remuneration policy relates to certain termination payments to key executives, including the Chief Executive Officer. In order to protect the Company's know-how and to ensure continuity in terms of attainment of business objectives, under the new policy, the Company may agree with certain executives with strategic and key responsibilities in the Company, including the Chief Executive Officer, to make payments for loss of office or employment in addition to the severance payment under the prevailing labour and legal conditions in their contracts or countries where they are employed if they should leave (by loss of office or employment) the Company within two years of a change in control. The payment will represent six months of remuneration and will be adjusted to ensure that total payment including severance payment required under prevailing laws represent at least 12 months of remuneration (including salary, benefits, long term incentive plans and variable pay), but never more than 24 months of remuneration, unless required by local law.

A change of control means that a third party or coordinated parties (i) acquire directly or indirectly by any means a number of shares in the Company which (together with the shares that such party may already hold in the Company) amount to more than 50% of the share capital of the Company; or (ii) appoint or have the right to appoint at least half of the members of the Board of Directors of the Company.

No other changes are to be made to the remuneration policy.

Resolution 3 to approve the directors' remuneration policy is a binding vote. If approved by shareholders, the directors’ remuneration policy will take effect immediately after the end of the AGM and all payments by the Company to directors and any former directors must be made in accordance with the policy (unless a payment has been separately approved by a shareholder resolution or was agreed before the AGM or before the person became a director). If the directors’ remuneration policy is approved and remains unchanged, it will remain in effect for up to three years without further shareholder approval being required. If the Company wishes to change the policy within three years, it will need to put the revised policy to shareholders before it can implement the new policy.

If the directors' remuneration policy is not approved for any reason, the Company will, if and to the extent permitted by the Companies Act 2006, continues to make payments to directors in accordance with existing contractual arrangements and will seek shareholder approval again at the next AGM or an earlier general meeting.

The Board recommends voting "For" this proposal.

Great West House, GW1, 17th Floor, Great West Road, Brentford TW8 9DF , London, UK, T + 44 203 547 8055 8

Notes to Resolutions 4 and 5 – Re-appointment of auditors and auditors' remuneration

It is the Company’s policy to ensure that, at least once every ten years, the audit services contract is put out to tender to enable the Audit Committee of the Company (“AC”) to compare the quality and effectiveness of the services provided by the incumbent auditor with those of the other audit firms.

The AC has the direct and sole responsibility for the appointment, compensation, retention, oversight and replacement, if necessary, of the external, independent auditor. The AC also considers and makes recommendations to the Board, to be put to shareholders for approval at the annual general meeting, in relation to the appointment, re-appointment and removal of the Company's external auditor and their remuneration, whether fees for audit or non-audit services, and that the level of fees is appropriate to enable an effective and high quality audit to be conducted.

The AC annually reviews the audit fee structure and terms of engagement.  Fees paid for Company external auditor services for 2016 were US$ 1,674,000 (see the Company’s 2016 Annual Report page 87 Auditor's remuneration).

In the AC meeting held on 10 March 2017, the members of the AC approved the re-appointment of Deloitte LLP and Deloitte S.L. as the Company's auditors.

Resolution 4, which is recommended by the AC, confirms this re-appointment of Deloitte LLP and Deloitte S.L. to hold office until the next general meeting at which accounts are laid before the Company.

The Board recommends voting "For" this proposal.

Resolution 5 seeks authority for the AC to determine the auditors' remuneration.

The Board recommends voting "For" this proposal.

Additionally, a director who retires at any annual general meeting shall be eligible for election or re-election unless the director resolves otherwise not later than the date of the notice of such annual general meeting.

· Proxy Statement: this Proxy Statement summarizes information about the proposals to be considered at the AGM and other information you may find useful in determining how to vote.

In addition to solicitations by mail, our directors, officers and regular employees, without additional remuneration, may solicit proxies by telephone, e-mail and personal interviews.

We are mailing the notice of 2017 AGM, the Proxy Statement and the Proxy Card to our shareholders of record as of 21 April 2017. In this mailing, we are also including our 2016 Annual Report for the year ended 31 December 2016 ("2016 Annual Report”).

Great West House, GW1, 17th Floor, Great West Road, Brentford TW8 9DF , London, UK, T + 44 203 547 8055 13

Questions and Answers about Voting

1.      Why am I receiving these materials?

We have sent you this Proxy Statement and the Proxy Card because our Board is soliciting your proxy to vote at the AGM, including at any adjournments or postponements of the AGM. You are invited to attend the AGM to vote on the proposals described in this Proxy Statement. However, you do not need to attend the AGM to vote your shares. Instead, you may simply complete, sign and return the enclosed Proxy Card.

We intend to mail this Proxy Statement and accompanying Proxy Card on or about 28 April 2017 to all shareholders of record entitled to vote at the AGM.

2.      Who can vote at the AGM?

Only shareholders of record at the close of business on the record date, 19 June 2017, (“Vote Record Date”) will be entitled to vote at the AGM.

Shareholder of Record: Shares Registered in Your Name

If, on the Vote Record Date, your shares were registered directly in your name with the transfer agent, Computershare Trust Company, NA ("Computershare") then you are the shareholder of record. As a shareholder of record, you may vote in person at the AGM or vote by proxy. Whether or not you plan to attend the AGM, we urge you to fill out and return the enclosed Proxy Card to ensure your vote is counted.

Beneficial Owner: Shares Registered in the Name of a Broker, Bank or Other Agent

If, on the Vote Record Date, your shares were held in an account at a brokerage firm, bank, dealer or other similar organization, then you are the beneficial owner of shares held in “street name” and these proxy materials are being forwarded to you by that organization. The organization holding your account is considered the shareholder of record for purposes of voting at the AGM. As a beneficial owner, you have the right to direct your broker or other agent on how to vote the shares in your account. You are also invited to attend the AGM. However, because you are not the shareholder of record, you may not vote your shares in person at the AGM unless you request and obtain a valid legal proxy card from your broker or agent.

3.      What constitutes a quorum?

For the purposes of the AGM, a quorum is present if at least two persons entitled to vote upon the business to be transacted, each being a member or a proxy for a member or a duly authorized representative of a corporation which is a member (including for this purpose two persons who are proxies or corporate representatives of the same member), between them, holding or representing by proxy at least one-third in nominal value of the issued shares.

Great West House, GW1, 17th Floor, Great West Road, Brentford TW8 9DF , London, UK, T + 44 203 547 8055 14

4.      How do I vote my shares?

Please note that voting on all resolutions will be conducted by way of poll rather than a show of hands. This is a more transparent method of voting as member votes are to be counted according to the number of shares held and is in accordance with the Company's Articles of Association.

If you hold shares in “street name” - you should follow the directions provided by your broker, bank or other nominee. You may submit instructions by telephone or via the internet to your broker, bank or other nominee, or request and return a paper Proxy Card to your broker, bank or other nominee. We will distribute physical ballots to anyone who wants to vote in person at the AGM. If you hold shares in “street name” and wish to vote at the AGM, you must obtain a legal proxy from your broker, bank or other nominee and present it to the inspector of election of the AGM with your ballot.

If you are a “shareholder of record” - you may appoint a proxy to vote on your behalf by marking, signing and dating the Proxy Card and returning it in the prepaid envelope provided or return it to Vote Processing, c/o Broadridge, 51 Mercedes Way, Edgewood, NY 11717; by 1.30 pm (London time) on 21 June 2017. Alternatively, you can vote in person by physical ballot at the AGM.

If you properly give instructions as to your proxy appointment by executing and returning a paper Proxy Card, and your proxy appointment is not subsequently revoked, your shares will be voted in accordance with your instructions.

5.      Who can be appointed as proxy?

A proxy does not need to be a member of the Company but must attend the AGM to represent you.  Your proxy could be the Chairman, another director of the Company or another person who has agreed to attend to represent you.

A member of the Company which is a corporation may authorise a person or persons to act as its representative(s) at the AGM. In accordance with the provisions of the Companies Act 2006, each such representative may exercise (on behalf of the corporation) the same powers as the corporation could exercise if it were an individual member of the Company, provided that they do not do so in relation to the same shares.

6.      How will my shares be voted if I do not specify how they should be voted?

If you sign and send your Proxy Card but do not indicate how you want your shares to be voted, your shares will be voted by the persons appointed as proxies in accordance with the recommendations of our Board of Directors.

7.      Can I change my vote or revoke a proxy?

A shareholder of record can revoke his or her proxy 48 hours before the time of voting at the AGM in several ways by:

(1) mailing a revised Proxy Card dated later than the prior Proxy Card;

Great West House, GW1, 17th Floor, Great West Road, Brentford TW8 9DF , London, UK, T + 44 203 547 8055 15

(2) voting in person at the AGM; or

(3) notifying our Company Secretary in writing that you are revoking your proxy. Your revocation must be received before the AGM to be effective.

If you hold shares in “street name” - you may change or revoke your voting instructions by contacting the broker, bank or other nominee holding the shares or by obtaining a legal proxy from such institution and voting in person at the AGM as described above under “How do I vote my shares?” See also “What if I plan to attend the AGM?”

8.      Who counts the votes?

Broadridge Financial Solutions ("Broadridge") has been engaged as our independent agent to tabulate shareholder votes. If you are a shareholder of record, your executed Proxy Card is returned directly to Broadridge for tabulation. If you hold your shares through a broker, your broker will return one Proxy Card to Broadridge on behalf of all of its clients.

9.      How are votes counted?

Votes will be counted by Broadridge, who will separately count “for” and “against” votes and abstentions. In addition, with respect to the election of directors, Broadridge will count the number of “withheld” votes received for the nominees. If your shares are held in “street name,” you will need to obtain a proxy form from the institution that holds your shares and follow the instructions included on that form regarding how to instruct your broker to vote your shares.

10.    How many votes do I have?

On each matter to be voted upon, every member who is present in person or by proxy shall have one vote for each ordinary share as of the Vote Record Date.

11.    What if I plan to attend the AGM?

Attendance at the AGM will be limited to shareholders as of the Vote Record Date. Each shareholder may be asked to present valid picture identification, such as a driver’s licence or passport. Shareholders holding shares in “street name” through brokerage accounts or by a bank or other nominee are required to show a brokerage statement or account statement reflecting share ownership as of the Vote Record Date in order to obtain admittance to the AGM. However, if you hold shares in "street name" you will not be allowed to vote at the AGM unless you obtain a legal proxy from your broker, bank or other nominee holding the shares.

12.    What if I return a Proxy Card but do not make specific choices?

If we receive a signed and dated Proxy Card and the Proxy Card does not specify how your shares are to be voted, your shares will be voted “for” the matters submitted for approval at the AGM.

Great West House, GW1, 17th Floor, Great West Road, Brentford TW8 9DF , London, UK, T + 44 203 547 8055 16

13.    How do you solicit proxies?

The initial solicitation of proxies may be supplemented by additional mail communications and by telephone, fax, e-mail, internet and personal solicitation by our directors, officers or other employees. No additional compensation for soliciting proxies will be paid to our directors, officers or other employees for their proxy solicitation efforts.

14.    What do I do if I receive more than one notice or Proxy Card?

If you hold your shares in more than one account, you will receive a notice or Proxy Card for each account. To ensure that all of your shares are voted, please sign, date and return all Proxy Cards. Please be sure to vote all of your shares.

15.    What if I have questions during the AGM?

If you wish to ask a question, please tell the Company Secretary on entry to the auditorium.

Please endeavour to keep your questions short and relevant to the resolution being discussed. In the interests of orderly conduct of the meeting, we will allocate a slot for shareholders' questions towards the end of the meeting and in light of time constraints would ask shareholders to limit questions to one question per shareholder.  Of course, if shareholders have further questions the Chairman will endeavour to accommodate these.

16.    May I bring a guest to the AGM?

The AGM is a private meeting of shareholders and their representatives. Guests are not entitled to attend the meeting as of right but they may be permitted entry at the absolute discretion of the Company.

Shareholders wishing to bring a guest must notify us in advance. Any shareholders wishing to bring a guest should contact Broadridge. Please see "Who is the transfer agent?" below for contact details. All guests must bring photographic proof of identity and enter the meeting at the same time as the shareholder.

17.    As a member, which materials can I require to the Company to publish on its website?

Members satisfying the thresholds in section 527 of the Companies Act 2006 can require the Company to publish a statement on its website setting out any matter relating to (a) the audit of the Company's accounts (including the auditor's report and the conduct of the audit) that are to be laid before the AGM; or (b) any circumstances connected with an auditor of the Company ceasing to hold office, that the members propose to raise at the AGM.  The Company cannot require the members requesting the publication to pay its expenses.  Any statement placed on the website must also be sent to the Company's auditors no later than the time it makes its statement available on the website.  The business which may be dealt with at the meeting includes any such statement that the Company has been required to publish on its website.
