AGGREKO PLC NOTICE OF ANNUAL GENERAL MEETING 2017

Letter from the Chairman

24 March 2017

To the holders of Ordinary Shares

DEAR SHAREHOLDER

I am pleased to be writing to you with details of our Annual General Meeting, which we are holding at the Radisson Blu Hotel, 301 Argyle Street, Glasgow G2 8DL on Thursday 27 April 2017 at 11.00 am. The formal notice of Annual General Meeting is set out on pages 5 and 6 of this document.

If you would like to vote on the resolutions to be considered at the Annual General Meeting but cannot attend the meeting, you can appoint a proxy to exercise all or any of your rights to attend, speak and vote at the meeting by completing the form of proxy sent to you with this circular and returning it to our Registrar at the address stated on the form. They must receive it by 11.00 am on Tuesday 25 April 2017. Alternatively, you may appoint a proxy electronically by logging on to the Registrar's website, http://shares.aggreko.com, provided that they receive details of your appointment by 11.00 am on Tuesday 25 April 2017.

The Aggreko plc Annual Report and Accounts for the year ended 31 December 2016 and a copy of this circular have been published on the Company's website at ir.aggreko.com/investors. If you have elected to receive Shareholder correspondence in hard copy form, then a copy of the Annual Report and Accounts will accompany this circular. Should you wish to change your election at any time, or if you wish to request a hard copy of the Annual Report and Accounts, you can do so by contacting our Registrar.

The following paragraphs provide an explanation of the resolutions to be considered at the Annual General Meeting.

Resolutions 1 to 19 will be proposed as ordinary resolutions. This means that for each of those resolutions to be passed, more than half of the votes cast must be in favour of the resolution. Resolutions 20 to 23 will be proposed as special resolutions. This means that for each of those resolutions to be passed, at least three-quarters of the votes cast must be in favour of the resolution.

ANNUAL REPORT AND ACCOUNTS (RESOLUTION 1)

This resolution deals with the receipt and adoption of the accounts for the financial year ended 31 December 2016 and the associated reports of the Directors and Auditors.

ANNUAL STATEMENT AND ANNUAL REPORT ON REMUNERATION (RESOLUTION 2)

Resolution 2 seeks approval of the Annual Statement by the Remuneration Committee Chairman set out on pages 94 to 98 and the Annual Report on Remuneration set out on pages 106 to 114 of the Annual Report and Accounts for the year ended 31 December 2016 ('Annual Report 2016').

We are required by law to seek Shareholders' approval in respect of the Annual Statement and Annual Report on Remuneration on an annual basis. The current Directors' Remuneration Policy was approved by Shareholders at the 2015 Annual General Meeting, and sets out the Company's policy applied to Directors' remuneration in 2016. The full Directors' Remuneration Policy is available on ir.aggreko.com/investors.

This vote is advisory in respect of the overall remuneration package and the Directors' entitlements to remuneration are not conditional upon this resolution being passed.

APPROVAL OF NEW REMUNERATION POLICY (RESOLUTION 3)

Resolution 3 seeks approval, on a binding basis, of a new Directors' Remuneration Policy set out on pages 99 to 105 of the Annual Report 2016. If Resolution 3 is approved, the new Directors' Remuneration Policy will remain in effect (unless further altered by shareholder vote) for three years commencing from the date of the 2017 Annual General Meeting. Once the Directors' Remuneration Policy is approved, the Company will not be able to make a remuneration payment to a current or prospective Director or a payment for loss of office, unless that payment is consistent with the Directors' Remuneration Policy or has otherwise been approved by a resolution of the Shareholders of the Company.

Aggreko's current Directors' Remuneration Policy was approved by Shareholders at the Annual General Meeting in 2015 and has governed the way the Company has paid its directors over the last two years. Although we are able to operate the current Directors' Remuneration Policy for an additional year, the Remuneration Committee has taken the opportunity over the last six months or so to undertake a comprehensive review, with the aim of ensuring that pay reinforces the Company's strategy, whilst continuing to motivate and retain executive talent at this critical time for Aggreko. In particular, the Remuneration Committee has noted outcomes from the recent Investment Association Remuneration Working Group (IARWG) consultation, and the call for flexibility in determining a remuneration policy which is more tailored to individual company circumstances.

As a result of this review, and having regard to the IARWG recommendations and Aggreko's strategy, the Remuneration Committee is asking Shareholders to approve a new remuneration policy for our Executive Directors, which the Remuneration Committee and the Board as a whole, consider to be appropriate for Aggreko at this time; incentivising short and long-term performance through continued use of the annual bonus and Long Term Incentive Plan respectively (albeit with lower opportunities) and using awards of restricted shares and much higher personal shareholding requirements to support shareholder alignment and talent retention. Further detail on the background to, and the reasons for, the proposed changes to the Directors' Remuneration Policy are included on pages 94 to 98 of the Annual Report 2016.

AGGREKO PLC NOTICE OF ANNUAL GENERAL MEETING 2017
03

We are asking Shareholders to approve a new Restricted Share Plan separately under Resolution 18.

FINAL DIVIDEND (RESOLUTION 4)

Shareholders are being asked to approve a final dividend of 17.74 pence per Ordinary Share for the year ended 31 December 2016. If Shareholders approve the recommended final dividend, it will be paid on 24 May 2017 to all Ordinary Shareholders who are on the register of members on 21 April 2017.

ELECTION AND RE-ELECTION OF DIRECTORS (RESOLUTIONS 5 TO 14)

The Company's Articles of Association require that all newly appointed Directors retire at the first Annual General Meeting following their appointment. Resolutions 5 and 6 refer to the Directors appointed since the last Annual General Meeting in 2016. Resolutions 7 to 14 refer to the Directors standing for re-election in line with the UK Corporate Governance Code, which states that all directors of FTSE 350 companies should be subject to annual election by Shareholders.

Biographical details for each of the Directors seeking election and re-election are set out in Appendix 1 on pages 10 and 11 of this document and are also available to view online at ir.aggreko.com/investors. The Board unanimously recommends the elections of Barbara Jeremiah and Miles Roberts (both were appointed to the Board on 7 March 2017). The Board also confirms that, following a formal performance evaluation, each of the Directors standing for re-election continues to perform effectively, demonstrates commitment to their role, and has the capacity to discharge their responsibilities fully, given their existing time commitments to other organisations. Therefore, the Board unanimously recommends the re-election of the Directors proposed.

EXTERNAL AUDITOR (RESOLUTIONS 15 AND 16)

These resolutions deal with the re-appointment of KPMG LLP as auditors of the Company and the authorisation of the Audit Committee to determine their remuneration.

AUTHORITY TO ALLOT SHARES (RESOLUTION 17)

In line with last year, this resolution will authorise the Directors to allot Ordinary Shares up to an aggregate nominal value of £4,126,149 (representing 85,376,067 Ordinary Shares of 4½/5% pence each). This amount represents approximately one-third of the issued ordinary share capital of the Company as at 7 March 2017, being the latest practicable date prior to the publication of this circular. As at 7 March 2017, the Company held no treasury shares and there were no warrants over Ordinary Shares.

The authority sought under this resolution will expire on the earlier of 30 June 2018 (the latest date by which the Company must hold an Annual General Meeting in 2018) or the conclusion of the Annual General Meeting of the Company to be held in 2018.

The Directors have no present intention to issue new shares other than in relation to the issue of shares under the Company's executive and employee share schemes.

RESTRICTED SHARE PLAN (RESOLUTION 18)

Following a thorough review of the Executive Directors' remuneration arrangements by the Remuneration Committee we are proposing to introduce the Aggreko 2017 Restricted Share Plan (the "RSP"), a summary of which is set out in Appendix 2 on pages 12 to 14 of this document. The new RSP forms an important element of the new Directors' Remuneration Policy which we are asking Shareholders to approve under Resolution 3. Further detail on the background to, and the reasons for, the proposal to seek Shareholder approval for the RSP are included on pages 94 to 98 of the Annual Report 2016. As required by the Listing Rules, we also are asking for separate approval of the new RSP under this resolution.

EMPLOYEE SHARESAVE PLANS (RESOLUTION 19)

The Aggreko UK Sharesave Plan 2007, the Aggreko International Sharesave Plan 2007 and the Aggreko US Employee Stock Purchase Plan (together the "2007 Sharesave Plans"), which were approved by Shareholders in 2007, will all expire on 25 April 2017. We are therefore proposing to introduce and are seeking Shareholder approval for the Aggreko UK Sharesave Plan 2017, the Aggreko International Sharesave Plan 2017 and the Aggreko US Employee Stock Purchase Plan 2017 (together the "2017 Sharesave Plans") to replace the 2007 Sharesave Plans.

The Directors consider all-employee share ownership and equity participation to be a key feature and successful component of the Company's overall remuneration strategy, as it has done for the last twenty years, allowing the Company to better align the interests of employees and Shareholders, whilst at the same time helping the Company to recruit, retain and motivate employees at all levels within the group and on a multi-jurisdictional basis. The Aggreko UK Sharesave Plan 2017 and the Aggreko US Employee Stock Purchase Plan also offer tax-advantages to participants in the UK and the US respectively in accordance with the legislation in those two jurisdictions. The 2017 Sharesave Plans are substantially similar to the 2007 Sharesave Plans, which they will replace. The 2017 Sharesave Plans also form an important element of the new Directors' Remuneration Policy, for which separate Shareholder approval is being sought. A summary of the principal terms of the 2017 Sharesave Plans is set out in Appendix 3 on pages 16 and 17 of this document.

AGGREKO PLC NOTICE OF ANNUAL GENERAL MEETING 2017

Letter from the Chairman

DISAPPLICATION OF STATUTORY PRE-EMPTION RIGHTS (RESOLUTIONS 20 AND 21)

Resolution 20 will be proposed as a special resolution and will authorise the Directors to disapply the statutory pre-emption rights of Shareholders on allotment of equity securities for cash up to an aggregate nominal value of £618,922 (representing 12,806,410 Ordinary Shares of 45th/5th pence each), being approximately 5% of the issued ordinary share capital of the Company as at 7 March 2017, being the latest practicable date prior to the publication of this circular. This resolution also disapplies statutory pre-emption rights to the extent necessary to facilitate rights issues.

Resolution 21 will also be proposed as a special resolution and will authorise the Directors to allot a further 5% of the issued ordinary share capital of the Company otherwise than in connection with a pre-emptive offer to existing Shareholders for the purpose of financing a transaction (or refinancing within six months of the transaction) which the Directors determine to be an acquisition or other capital investment contemplated by the Pre-Emption Group's revised Statement of Principles, published on 12 March 2015 (the "PEG Principles").

This additional disapplication authority is in line with the PEG Principles, and provides the Company with greater flexibility by allowing the Company to allot shares with a nominal value of £618,922 (representing 5% of the issued ordinary share capital of the Company as at 7 March 2017) for cash pursuant to this authority where that allotment is in connection with an acquisition or specified capital investment (as described in the PEG Principles) which is announced at the same time as the allotment, or which has taken place in the preceding six-month period and is disclosed in the announcement of that allotment.

The Board does not intend to allot shares for cash on a non-pre-emptive basis above 7.5% of the total issued ordinary share capital of the Company over a rolling three-year period without consulting Shareholders first. This complies with the PEG Principles.

The authority under these Resolutions will expire at the conclusion of the Annual General Meeting to be held in 2018 or on 30 June 2018, whichever is the earlier. The Directors intend to seek renewal of this power at subsequent Annual General Meetings.

PURCHASE OF OWN SHARES (RESOLUTION 22)

The Directors recommend that Shareholders renew the authority of the Company to purchase its own Ordinary Shares. Accordingly, this resolution will be proposed as a special resolution seeking authority to make such purchases in the market. The Directors will only use this authority when they consider it to be in the best interests of Shareholders generally and an improvement in earnings per share would result. Any Ordinary Shares purchased under this authority will either be cancelled (and the number of Ordinary Shares in issue reduced) or be held in treasury.

This resolution specifies the maximum number of Ordinary Shares which may be purchased (representing approximately 10% of the Company's issued ordinary share capital as at 7 March 2017, being the latest practicable date prior to the publication of this circular) and the minimum and maximum prices at which they may be bought, reflecting the requirements of the Companies Act 2006 and of the Financial Conduct Authority, as set out in the Listing Rules. The Directors intend to seek renewal of this power at subsequent Annual General Meetings.

As at 7 March 2017, there were options over 1,866,723 Ordinary Shares in the capital of the Company which represented 0.73% of the Company's issued ordinary share capital at that date. If the authority to purchase the Company's Ordinary Shares were exercised in full, these options would represent 0.81% of the Company's issued ordinary share capital.

NOTICE OF GENERAL MEETINGS (RESOLUTION 23)

Under the Companies Act 2006, all general meetings of the Company must be held on 21 clear days' notice unless Shareholders agree to a shorter notice period on an annual basis and certain other conditions are met. The Company is currently able to call general meetings (other than Annual General Meetings) on 14 clear days' notice. The Board is proposing this resolution as a special resolution at the Annual General Meeting so that the Company can continue to be able to convene general meetings on 14 clear days' notice. The Board intends that this shorter notice period would not be used as a matter of routine, but would only be used where the flexibility was justified by the business of the meeting and it would be to the advantage of Shareholders as a whole. If this resolution is passed, the authority to convene general meetings on 14 clear days' notice will remain effective until the Company's next Annual General Meeting, when it is intended that a similar resolution will be proposed. The notice period for Annual General Meetings will remain 21 clear days.

RECOMMENDATION

The Board considers that all the resolutions to be considered at the Annual General Meeting are in the best interests of the Company and its Shareholders as a whole. Your Board will be voting in favour of them and unanimously recommends that you do so as well.

Yours sincerely

Ken Hanna
Chairman

Notes

5. Appointment of a proxy through CREST

CREST members who wish to appoint a proxy or proxies through the CREST electronic proxy appointment service may do so by using the procedures described in the CREST Manual and by logging on to the following website: www.euroclear.com/CREST. 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 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 (available via www.euroclear.com/CREST). 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 Registrar (CREST ID RA10) no later than 48 hours (excluding non-working days) before the time of the Annual General Meeting or any adjournment of that 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 Application Host) from which the Registrar 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 provider(s) should note that Euroclear UK & Ireland Limited does not make available special procedures in CREST for any particular message. 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/her 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 system 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.

6. Appointment of a proxy by joint holders

In the case of joint holders, where more than one of the joint holders purports to appoint one or more proxies, only the purported 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).

7. Corporate representatives

Any corporation which is a member can appoint one or more corporate representatives. Members can only appoint more than one corporate representative where each corporate representative is appointed to exercise rights attached to different shares. Members cannot appoint more than one corporate representative to exercise the rights attached to the same share(s).

8. Entitlement to attend and vote

To be entitled to attend and vote at the Annual General Meeting (and for the purpose of determining the votes they may cast), members must be registered in the Company's register of members at 5.00 pm on Tuesday 26 April 2016 (or, if the Annual General Meeting is adjourned, at 5.00 pm on the day two days prior to the adjourned meeting). Changes to the register of members after the relevant deadline will be disregarded in determining the rights of any person to attend and vote at the Annual General Meeting.

9. Nominated persons

Any person to whom this notice is sent who is a person nominated under Section 146 of the Companies Act 2006 (the "Act") to enjoy information rights (a "Nominated Person") may, under an agreement between him/her and the member 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 member as to the exercise of voting rights.

AGGREKO PLC NOTICE OF ANNUAL GENERAL MEETING 2017

Appendix 2

SUMMARY OF THE PRINCIPAL TERMS OF THE AGGREKO 2017 RESTRICTED SHARE PLAN

Operation

The Remuneration Committee of the Board of Directors of the Company (the "Committee") will supervise the operation of the Aggreko 2017 Restricted Share Plan (the "Plan").

Eligibility

Any employee (including an Executive Director) of the Company and its subsidiaries will be eligible to participate in the Plan at the discretion of the Committee.

Grant of awards

The Committee may grant awards to acquire ordinary shares in the Company ("Shares") within six weeks of shareholder approval of the Plan. The Committee may also grant awards within six weeks following the Company's announcement of its results for any period, the end of a closed period, the date of approval by Shareholders of a new Directors' Remuneration Policy or at any other time when the Committee considers there are sufficiently exceptional circumstances which justify the granting of awards. It is intended that the first awards will be made shortly following the adoption of the Plan.

The Committee may grant awards as conditional shares, nil (or nominal) cost options or as forfeitable shares. The Committee may also decide to grant cash-based awards of an equivalent value to share-based awards or to satisfy all or part of share-based awards in cash, although it does not currently intend to do so. This is likely where there are restrictions on the issue of shares or particular circumstances such as where exchange control restrictions in a country do not allow the use of share-based awards.

An award may not be granted more than 10 years after shareholder approval of the Plan.

No payment is required for the grant of an award. Awards are not transferable, except on death. Awards are not pensionable.

Individual limit for Executive Directors

An Executive Director may not receive awards under the Plan in any financial year over Shares having a market value in excess of 75 per cent. of his or her annual base salary (as at the time of grant) in that financial year, or such higher (or lower) percentage of annual salary that is permitted under the shareholder approved Directors' Remuneration Policy that is in force at that time.

Individual limit for below Board employees

The aggregate market value of Shares over which awards are granted in a financial year to an employee who is not an Executive Director (at grant) will normally be limited to an amount up to 100 per cent. of annual base salary (as at the time of grant) for which purposes salary may include salary supplementary allowance for employees in India only. If, however, the Committee determine that the circumstances are sufficiently exceptional, including but not limited to the recruitment or retention of a key employee, the Committee may grant awards to an employee (other than an Executive Director) over Shares that have an aggregate market value worth up to 200 per cent. of annual base salary in a financial year.

Performance conditions

The vesting of awards may be subject to performance conditions set by the Committee. There is currently no intention to impose any performance conditions to any award granted to an Executive Director under the Plan.

Performance related awards to the Executive Directors will normally be granted under the Aggreko 2015 Long Term Incentive Plan, which was approved by Shareholders in 2015 or such other replacement plan.

Awards (including to Executive Directors) may be subject to a general performance underpin. If the performance underpin is not satisfied, the Committee may scale back the vesting of awards (including to zero).

To the extent that a performance condition does apply the Committee may vary, or waive and replace, that performance condition if an event has occurred which causes the Committee to consider that it would be appropriate to amend, or waive and replace, the performance condition. Any varied or replacement condition must, in the opinion of the Committee, be fair and reasonable and not materially less challenging than the original condition.

Vesting of awards

Awards normally vest three years after grant provided the participant is still an officer or employee within the Company's group and, if a performance condition applies, to the extent that the condition has been satisfied. An award granted to an employee who is not also an Executive Director (on grant) may under normal circumstances vest earlier or later than the third anniversary of the date of grant to the extent determined by the Committee on or before the grant of that award.

Vested awards that have been structured as options are exercisable up until the tenth anniversary of grant unless they lapse earlier.

Holding periods

Unless the Committee determines otherwise, the Company's Executive Directors will normally be required to retain any Shares acquired on the vesting or exercise of an award (less a number of shares that have an aggregate market value on vesting or, in the case of an option, exercise equal to the tax liability due on vesting or exercise) until the expiry of a holding period set by the Committee at grant. The holding period applying to initial awards granted to the Company's Executive Directors will normally end on the fifth anniversary of the date of grant of the award under which the Shares were acquired or if earlier the second anniversary of the date of Vesting of the relevant award (for example, where an award vests early on cessation of employment).

AGGREKO PLC NOTICE OF ANNUAL GENERAL MEETING 2017 13

The holding period may also apply to Shares held by participants who are below Executive Director level.

The relevant holding period will end early on or shortly prior to:

(a) the occurrence of a takeover, scheme of arrangement or winding-up of the Company (excluding an internal reorganisation where awards are exchanged for replacement awards, in which circumstances the holding period shall apply to the replacement securities);

(b) the death of a participant; or

Participants in the Plan who are subject to a holding period shall not be restricted or prevented during the relevant holding period from taking up any shareholder rights that they may have in relation to the Shares subject to the holding period. The terms and basis upon which Shares must be held during the holding period shall be determined by the Committee.

Dividend equivalents

The Committee may decide that participants will receive a payment (in cash and/or Shares), on or shortly following the vesting or exercise of their awards, of an amount equivalent to the dividends that would have been paid on those Shares between the time when the awards were granted and the time when they vest or, in the case only of Shares held under an option that is subject to a holding period, the earlier of the exercise date of that option and the date on which the applicable holding period ends. This amount may assume the reinvestment of dividends. Alternatively, participants may have their awards increased as if dividends were paid on the Shares subject to their award and then reinvested in further Shares.

Leaving or transferring employment

The treatment of awards held by leavers will depend upon whether or not the participant left the Company's group within one year of the award being granted and the reason for leaving.

(a) Leaving employment within one year of an award being granted

An award will normally lapse upon a participant ceasing to hold employment or be a Director within the Company's group for any reason within one year of that award being granted unless the Committee determines that the circumstances are, in its opinion, sufficiently exceptional, in which case an award may vest on any date, as determined by the Committee, and to the extent determined by the Committee (having regard to any performance conditions and the period during which the participant was employed from grant) and subject to any other additional terms and conditions that the Committee may determine.

(b) Leaving employment a year or more after an award has been granted

An award will lapse upon a participant ceasing to hold employment or be a Director within the Company's group one year or more after that award has been granted unless the participant leaves as a 'good leaver' (see below).

A participant will be treated as a good leaver if he or she ceases to be an employee or a Director by reason of his or her death, injury, ill-health, disability, retirement, redundancy, his or her employing company or the business for which he or she works being sold or transferred out of the Company's group or in other circumstances at the discretion of the Committee. If a participant is a good leaver, then his or her award will vest when it would have vested if he or she had not ceased such employment or office, unless the Committee determines otherwise, in which case the award will vest earlier upon such cessation occurring (or shortly thereafter). The extent to which an award will vest in these situations will depend upon two factors: (i) the extent to which any performance conditions have been satisfied over the original performance period or (if the award is to vest early) over such shorter period determined by the Committee; and (ii) the pro-rating of the award to reflect the reduced period of time between its grant and the date of cessation relative to the original vesting period, although the Committee can decide not to pro-rate an award (or to vary the time pro rata reduction) if it regards it as appropriate to do so in the particular circumstances.

The Committee retains discretion to vary (up or down) the extent and the time when awards vest upon a participant ceasing to be a Director or employee within the Company's group on a case-by-case basis, to ensure fairness for both Shareholders and participants.

The Committee may, in its discretion, also permit an award to vest early in the event that a participant's office or employment, or place of work, is to be transferred within the group and such transfer is likely to give rise to adverse tax consequences. In these circumstances, the extent to which an award vests and the date of vesting will be determined by the Committee in its discretion.

Corporate events

In the event of a takeover, or another company acquires control of the Company under a scheme of arrangement, or upon a winding-up of the Company (not being an internal corporate reorganisation or reconstruction) (a "Corporate Event"), all awards held for less than one year at the time of the relevant Corporate Event will lapse, unless the Committee determines that the circumstances are, in its opinion, sufficiently exceptional, in which case an award may vest to the extent determined by the Committee (having regard to any performance conditions) and subject to any other additional terms and conditions. Awards that have been held for at least one year at the time of the relevant Corporate Event will vest early subject to the extent that any performance conditions have been satisfied at that time or, in the opinion of the Committee, would have been satisfied were it not for that event.

In the event of an internal corporate reorganisation or reconstruction or merger, awards will be replaced by equivalent new awards over shares in a new holding company unless the Committee decides that awards should vest on the basis which would apply in the case of a takeover.

If a demerger is proposed which, in the opinion of the Committee, would affect the market price of Shares to a material extent, then the Committee may, in its discretion, decide that awards will vest (irrespective of when they were granted) to the extent that, in the opinion of the Committee, any performance conditions have been satisfied or would have been satisfied and on such terms decided by the Committee.

AGGREKO PLC NOTICE OF ANNUAL GENERAL MEETING 2017

Appendix 2

The Committee retains discretion to vary (up or down) the extent to which and the time when awards vest upon the occurrence of a Corporate Event or a demerger on a case-by-case basis, following a review of the circumstances, to ensure fairness for both Shareholders and participants.

Malus and clawback

The Plan includes malus and clawback provisions under which the Committee may, in its discretion, reduce the number of Shares held under an award before it vests. The Committee may also seek to recover any overpayment, or Shares that have vested, under the Plan within three years of that award vesting. In particular, the malus and clawback provisions may be operated by the Committee where there has been a material misstatement of the Company's results or accounts and/or an error is made in assessing the satisfaction of a performance condition and such material misstatement and/or error resulted (directly or indirectly) in an award being granted over a larger number of Shares and/or an award vesting to a greater degree than would otherwise have been the case. The Committee may also operate malus and clawback where a participant has committed an act of gross misconduct or where other exceptional circumstances have arisen which, in the opinion of the Committee, justify the operation of malus and clawback.

Participants' rights

Awards of conditional Shares and options will not confer any shareholder rights until the awards have vested or the options have been exercised and the participants have received their Shares. Holders of awards of forfeitable Shares will have shareholder rights from when the awards are made except they may be required to waive their rights to receive dividends.

Rights attaching to Shares

Any Shares allotted when an award vests or is exercised will rank equally with Shares then in issue (except for rights arising by reference to a record date prior to their allotment).

Variation of capital

In the event of any variation of the Company's share capital or in the event of a demerger, payment of a special dividend or similar event which materially affects the market price of the Shares, the Committee may make such adjustment as it considers appropriate to the number of Shares subject to an award and/or the exercise price payable (if any).

Overall Plan limits

The Plan may operate over new issue Shares, treasury Shares (i.e. Shares held by the Company in treasury) or Shares purchased in the market.

In any 10 calendar year period, the Company may not issue (or grant rights to issue) more than:

(a) 10 per cent. of the issued Ordinary Share capital of the Company under the Plan and any other employee share plan adopted by the Company; and
(b) 5 per cent. of the issued Ordinary Share capital of the Company under the Plan and any other executive share plan adopted by the Company.

Treasury Shares will count as new issue Shares for the purposes of these limits unless institutional investors decide that they need not count.

Alterations to the Plan

The Committee may, at any time, amend the Plan or the terms of an award in any respect, provided that the prior approval of Shareholders is obtained for any amendments that are to the material advantage of participants in respect of the rules governing eligibility, limits on participation, the overall limits on the issue of Shares or the transfer of treasury Shares, the basis for determining a participant's entitlement to, and the terms of, the Shares or cash to be acquired and the adjustment of awards.

The requirement to obtain the prior approval of Shareholders will not, however, apply to any minor alteration made to benefit the administration of the Plan or an award, to take account of a change in legislation or to obtain or maintain favourable tax, exchange control or regulatory treatment for participants or for any company in the Company's group. Shareholder approval will also not be required for any amendments to any performance condition applying to an award.

Overseas Plans

The Plan also incorporates a separate schedule for employees who are residents of the State of California on the date of grant of an Award (the "CA Schedule"). The CA Schedule is required to comply with the requirements of Section 25102(o) of the California Corporate Securities Law of 1968, as amended or re-enacted, and the regulations issued thereunder by the California Commissioner of Corporations. Awards issued to employees under the CA Schedule will be granted subject to the same limits and performance conditions and on substantially the same terms as those applying to awards granted under the main body of the Plan.

The shareholder resolution to approve the Plan will also allow the Board to establish further plans and/or schedules to the Plan for other overseas territories, any such plan and/or schedule to be similar to the Plan, but modified to take account of local tax, exchange control or securities laws, provided that any Shares made available under such further plans are treated as counting against the limits on individual and overall participation in the Plan. In particular, the Plan authorises the Committee or the Board of Directors to approve and adopt a French schedule to the Plan under which either French-qualified share options or French-qualified conditional share awards may be granted in compliance with the relevant provisions of The French Commercial Code.

Appendix 3

SUMMARY OF THE PRINCIPAL TERMS OF THE AGGREKO UK SHARESAVE PLAN 2017, THE AGGREKO INTERNATIONAL SHARESAVE PLAN 2017 AND THE AGGREKO US EMPLOYEE STOCK PURCHASE PLAN 2017

Introduction

The following is a summary of the principal terms of the Aggreko UK Sharesave Plan 2017 (the "UK Plan"), the Aggreko International Sharesave Plan 2017 (the "International Plan") and the Aggreko US Employee Stock Purchase Plan 2017 (the "US Plan" and together with the UK Plan and the International Plan known as the "Plans").

The Plans will replace the Aggreko UK Sharesave Plan 2007, the Aggreko International Sharesave Plan 2007 and the Aggreko US Employee Stock Purchase Plan 2007, which were approved by Shareholders in 2007 and will expire on 25 April 2017.

The principal terms of the Plans are substantially the same unless expressly indicated to the contrary.

Operation

The operation of the Plans will be supervised by the Board of Directors of the Company or an authorised committee of (or approved by) the Board of Directors (the "Board").

The UK Plan is a UK tax advantaged share option scheme and is intended to comply with the requirements of Schedule 3 to the Income Tax (Earnings and Pensions) Act 2003 ("Schedule 3"), as amended and re-enacted from time to time.

The US Plan is a US tax advantaged share option plan and is intended to comply with section 423 of the US Internal Revenue Code of 1986 (the "Code"), as amended and re-enacted from time to time.

Eligibility

The UK Plan provides that employees and full-time Directors of the Company and any designated participating subsidiary who are UK resident taxpayers, are eligible to participate. The Board may in its discretion extend participation under the UK Plan to other employees or directors of participating members of the Group who do not meet these requirements.

The International Plan provides that employees of the Company and any designated participating subsidiary in any jurisdiction are eligible to participate in the International Plan at the discretion of the Board.

The US Plan requires that employees and full-time Directors of the Company and any designated participating subsidiary in the United States of America are eligible to participate in the US Plan.

The Plans provide that the Board may require employees to have completed a qualifying period of employment (a "Qualifying Period") before they may apply for the grant of an option. In particular, under the UK Plan and the US Plan the Board may specify a Qualifying Period of up to 5 years and 2 years respectively. The Qualifying Period under the International Plan is determined by the Board at its discretion.

The intention is that participation in the UK Plan will be limited to eligible employees of the Company and its UK based subsidiaries who are resident in the UK; participation in the US Plan will be limited to eligible employees of the Company's US subsidiaries; and, participation in the International Plan may be offered to eligible employees who do not qualify to participate in either the UK Plan or the US Plan, and who are employed by subsidiaries of the Company, and work in jurisdictions chosen by the Board, in its discretion. As a general rule, employees will not be invited to participate in more than one of the Plans in a financial year.

Grant of options

Options to acquire ordinary shares in the capital of the Company (a "Share") can only be granted to employees who agree to enter into a savings contract under which monthly savings are normally made out of net income over a period of three or five years, or two years only under the US Plan.

The International Plan only also has the facility for the Board to allow eligible employees to agree to sacrifice a portion of their gross salary and for eligible employees to pay into a pension or other investment fund or savings vehicle approved by the Board. Furthermore, under the terms of the International Plan only the Board may also decide to grant cash-based awards of an equivalent value to share-based awards or to satisfy share-based awards in cash. The Board may also decide to grant or settle an option under the International Plan only as a share appreciation right.

Options will normally be granted within 30 days (or 42 days if applications are scaled back) of the first day by reference to which the option price is set. The number of Shares over which an option is granted will be such that the total option price payable for those Shares will correspond to the proceeds on maturity of the related savings contract (or, in the case only of the International Plan, the aggregate deductions made from salary over the relevant savings period or the aggregate contributions to the relevant pension or investment vehicle).

No invitation may be issued under the Plans more than 10 years after the Plans are approved by Shareholders.

Timing of invitations

Invitations to participate in the Plans may be issued within 42 days after (i) the approval of the Plans by Shareholders; (ii) the announcement of the Company's results for any period, (iii) the date on which any change to the legislation affecting UK Schedule 3 sharesave schemes takes effect, (iv) the date on which a new UK savings contract prospectus is announced or takes effect, or (v) the end of a closed period. Invitations may also be issued at any other time at which the Board determines that the circumstances are sufficiently exceptional to justify the grant of options.

Invitations to participate in the Plans will normally be made at or around the same time to all eligible employees and, in respect of the International Plan, to employees chosen by the Board.

AGGREKO PLC NOTICE OF ANNUAL GENERAL MEETING 2017

Appendix 3

If, for any reason, an invitation is mistakenly not issued to an employee under the International Plan who the Board determined should have been invited (the "original invitation") then the Board may, in its discretion, within three months of the date of grant of the option under the original invitation, re-issue the original invitation to that eligible employee only on terms which will allow them to participate on substantially the same terms as the original invitation (including at the same option price).

Individual participation

Subject to the limits set out below, the Board will determine the maximum amount that an employee may contribute under a savings contract linked to options granted under the Plans.

Monthly savings by an employee under the UK Plan and all savings contracts linked to options granted under any Schedule 3 tax advantaged scheme may not exceed the statutory maximum (currently £500 per month in aggregate). Similarly, monthly savings by an employee under the International Plan and all savings contracts linked to options granted under the International Plan and any other similar sharesave scheme established by the Company may not normally exceed the overseas equivalent of the statutory maximum amount as may from time to time be permitted under the UK Plan.

Monthly savings by an employee under the US Plan and all savings contracts linked to options granted under the US Plan and any other similar plan established by the Company in accordance with the Code may also not normally exceed the US equivalent of the statutory maximum under the UK Plan, subject to an overall cap of US$1,000 per month in aggregate or such other amount as may from time to time be determined by the Board and is permitted under the Code.

The Board may allow participants under the US Plan and the International Plan to save in any currency permitted by the Board and as specified in the invitation. The Board may also allow participants under the US Plan (to the extent permitted by the Code) and the International Plan to make up for any missed contributions at the end of the savings contract (subject to a maximum of six missed monthly contributions) and to top-up their savings so that they may exercise their option in full, for example, to take account of any exchange rate fluctuations which have reduced the value of their savings.

Option price

The option price per Share under the UK Plan and the International Plan will be the market value of a Share when invitations to participate in the UK Plan and International Plan are issued less a discount of up to 20 per cent (or, in the case of an option to subscribe, the nominal value of a Share if higher), or such other maximum discount permitted under the governing legislation. Market value is determined as the average of the middle market quotations of a Share as derived from the Daily Official List of the London Stock Exchange over the three dealing days before invitations to participate in the UK Plan and International Plan are sent out or, if the Board so decides, the average of the middle market quotation on the last dealing day before invitations are issued, or such other date permitted by HMRC.

The option price per Share under the US Plan will be the average fair market value of a Share over the three dealing days immediately prior to the date of grant of an option, or the fair market value of a Share on or preceding the grant date (or such other dates permitted under the Code) as determined by the Board in accordance with the Code less a discount of up to 15 per cent or such other maximum discount permitted under the Code.

In respect of the US Plan and the International Plan the Board may convert the option exercise price into US dollars or any other currency chosen by the Board either at or around the date of an invitation or the grant of an option on such basis as the Board decides. Alternatively, the Board may convert the option exercise price into another currency at the end of the savings contract on such basis as the Board decides.

Exercise and lapse of options

Options granted under the UK Plan and the International Plan will normally be exercisable for a six month period from the end of the relevant three or five year savings contract.

Options granted under the US Plan will normally become exercisable from the second anniversary of the date of deduction of the first contribution to the savings contract and will remain exercisable until the expiry of the period of 27 months from the date of grant of the option or such other period permitted under the Code.

Any options not exercised within the relevant exercise period will lapse.

An option may be exercised before the end of the relevant savings period, for a limited period, on the death of a participant or on his or her ceasing to hold office or employment within the group or with an associated company by reason of injury, disability, redundancy, retirement, the sale or transfer out of the group of his or her employing company or business, their employer ceasing to be an associated company or (in the case of the UK Plan and the International Plan) for any other reason (provided in such case the option was granted more than three years previously).

Takeovers and Liquidations

Rights to exercise options early for a limited period also arise if another company acquires control of the Company as a result of a takeover or upon a scheme of arrangement or becomes bound or entitled to acquire shares under the compulsory acquisition provisions. An option may be exchanged for an option over shares in the acquiring company if the participant so wishes and the acquiring company agrees.

If the Company passes a resolution for a voluntary winding-up, any subsisting option must be exercised within a period of up to six months of the passing of that resolution or it lapses.

AGGREKO PLC NOTICE OF ANNUAL GENERAL MEETING 2017 17

Satisfying options and overall plan limits

The Plans may operate over new issue Shares, treasury Shares or Shares purchased in the market.

In any ten calendar year period, the Company may not issue (or create the possibility of issuing) more than 10 per cent. of the issued ordinary share capital of the Company under the Plans and any other employee share plan adopted by the Company.

Treasury Shares will count as new issue Shares for the purposes of these limits unless institutional investors decide that they need not count.

Variation of capital

In the event of any variation in the share capital of the Company, adjustments to the number of Shares subject to options and the exercise price may be made by the Board in such manner and with effect from such date as the Board may determine to be appropriate.

Rights attaching to Shares

Until options are exercised, option holders have no voting or other rights in respect of the Shares subject to their options.

Shares issued or transferred pursuant to the Plans shall rank pari passu in all respects with the Shares already in issue except that they will not rank for any dividend or other distribution paid or made by reference to a record date falling prior to the date of exercise of the option.

Benefits obtained under the Plan shall not be pensionable.

Options are not assignable or transferable.

Alterations to the Plans

The Board may, at any time, amend the provisions of the Plans in any respect, provided that the prior approval of Shareholders is obtained for any amendments that are to the material advantage of participants in respect of the rules governing eligibility, limits on participation, the overall limits on the issue of Shares or the transfer of treasury Shares, the basis for determining a participant's entitlement to, and the terms of, the Shares to be acquired and the adjustment of options.

The requirement to obtain the prior approval of Shareholders will not, however, apply to any change required to ensure that the UK Plan and the US Plan comply with Schedule 3 and the Code respectively, securities laws or to any minor alteration made to benefit the administration of the Plans, to take account of a change in legislation or to obtain or maintain favourable tax, exchange control or regulatory treatment for participants or for any company in the Company's group.

Overseas plans

The Board may, without further Shareholder approval, establish further plans or schedules to the International Plan for overseas territories, any such plan or schedule to be similar to the International Plan, but modified to take account of local tax, exchange control, securities laws and other relevant local laws, regulation and practice, provided that any Shares made available under such further plans are treated as counting against the limits on individual and overall participation in the International Plan. In particular, the Plan authorises the Committee or the Board of Directors to approve and adopt a French Schedule to the Plan under which French-qualified share options may be granted in compliance with the relevant provisions of the French Commercial Code.

The US Plan incorporates a separate schedule for employees who are resident in the State of California in compliance with Californian state securities laws.
