THIS IMPLEMENTATION AGREEMENT is made on 13 February 2014

BETWEEN:

(1)                                 AMEC PLC (registered in England and Wales with registered number 1675285) whose registered office is at Booths Park, ▇▇▇▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇, ▇▇▇▇ ▇▇▇, ▇▇ (“AMEC”); and

(2)                                 ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ AG (registered in Switzerland with registered number CHE-114.603.783) whose registered office is at ▇▇▇▇▇▇▇▇▇▇▇▇▇ ▇▇, ▇▇▇▇ ▇▇▇▇, (▇▇▇▇▇▇ ▇▇ ▇▇▇), ▇▇▇▇▇▇▇▇▇▇▇ (the “Company”),

each a “party” and together, the “parties”.

WHEREAS:

(A)                               The parties intend to announce the recommended cash and stock acquisition of the entire issued and to be issued share capital of the Company by AMEC on the terms and subject to the conditions referred to in this agreement (the “Agreement”) and as set out in the Offer Documents.

(B)                               The Company Board has determined in good faith that this Agreement and the Offer are in the best interests of the Company and fair to the Company Shareholders.

(C)                               The AMEC Board has determined in good faith that this Agreement and the Offer are in the best interests of AMEC and fair to the AMEC Shareholders.

(D)                               The parties desire to make certain warranties, arrangements and covenants in relation to the Acquisition as contemplated in this Agreement.

(E)                                Subject to the terms and conditions of this Agreement and applicable Laws, it is the parties’ intention that, following the purchase of the Company Shares in the Offer, the Company will merge with and into MergeCo, with MergeCo as the surviving corporation in such merger, as described in further detail in clause 4 of this Agreement.

(F)                                 For United States federal income tax purposes, the parties intend upon completion of the Offer to undertake the Squeeze-Out Merger, such transactions to be integrated and to qualify as a “reorganization” within the meaning of Section 368(a) of the United States Internal Revenue Code of 1986, as amended (the “Code”), and that this Agreement constitutes a “plan of reorganization” for purposes of Sections 354, 361 and 368 of the Code.

(G)                               Unless otherwise stated, words and expressions used in this Agreement shall have the meaning given to them in, and be interpreted in accordance with, Schedule 1.

NOW THEREFORE, in consideration of the mutual covenants and agreements set forth herein, the parties agree as follows:

1.                                      THE OFFER

1.1                               Immediately following the execution of this Agreement or at an alternative time and date as may be agreed by the parties, the parties shall procure the release of their respective Press Announcements.

1.2                               In accordance with the Timetable, AMEC agrees and undertakes to the Company to commence, or to cause a direct wholly-owned subsidiary to commence, (within the meaning

of Rule 14d-2 under the Exchange Act) a public exchange offer to acquire all of the issued and to be issued Company Shares. In the Offer, each Company Share accepted by AMEC or its direct wholly-owned subsidiary shall be exchanged for the right to receive from AMEC a combination (at the election of such holder in accordance with clause 1.3) of (a) $16.00 in cash plus (b) 0.8998 Offer Securities (the aggregate of such consideration per Company Share, or any greater amount per Company Share, paid pursuant to the Offer being hereinafter referred to as the “Offer Price”), in each case, less any Taxes required to be withheld as set out in clause 1.13; on the terms and subject to the conditions referred to in this Agreement (such offer, as may be amended from time to time as permitted by this Agreement, the “Offer”). Holders of Company Shares who validly accept the Offer may elect to vary the proportions in which they receive Share Consideration and Cash Consideration in accordance with clause 1.3.

1.3                               Subject to clause 1.3(e), each holder of Company Shares may elect to receive Cash Consideration or Share Consideration (in either case without interest) in exchange for each of such holder’s Company Shares in accordance with the procedures set forth in this clause 1.3:

(a)                                 The letter of transmittal included in the Offer Documents shall permit the holder to specify: (i) the number of such holder’s Company Shares with respect to which such holder elects to receive 1.7996 Offer Securities for each such Company Share (the “Share Consideration”), including whether in the form of ADSs or AMEC Shares (such election, a “Share Election” and any shares subject to such election, “Share Election Shares”), (ii) the number of such holder’s Company Shares with respect to which such holder elects to receive $32.00 in cash for each such Company Share (such amount, the “Cash Consideration”, such election, a “Cash Election” and any shares subject to such election, “Cash Election Shares”) and (iii) in the event the holder’s Company Shares are Share Consideration Designated Shares, whether such holder prefers ADSs or AMEC Shares. A holder may elect to receive the Share Consideration or the Cash Consideration, or make no election, for any number of such holder’s Company Shares (any shares not subject to any election, “No Election Shares”);

(b)                                 In connection with the Offer Closing, AMEC shall cause the Exchange Agent to effect the allocation among the holders of Company Shares of rights to receive Cash Consideration or Share Consideration pursuant to the Offer in accordance with the letters of transmittal as follows:

(i)                 If the aggregate cash amount that would be paid in consideration for all Company Shares with respect to which a Cash Election was made is greater than the product of (x) the Total Cash Available and (y) the Acceptance Fraction, then:

(A)                               all Share Election Shares and No Election Shares shall be exchanged for the right to receive the Share Consideration;

(B)                               the Exchange Agent shall then select from among the Cash Election Shares, by a pro rata selection process, a sufficient number of shares, which shall be treated as Share Election Shares (such shares being the “Share Consideration Designated Shares”) such that the aggregate cash amount that will be paid in the Offer equals as closely as practicable to an amount equal to the product of (x) the Total Cash Available and (y) the Acceptance Fraction, and all Share Consideration Designated Shares shall be exchanged for the right to receive the Share Consideration; and

2

(C)                               the Cash Election Shares that are not Share Consideration Designated Shares will be exchanged for the Cash Consideration;

(ii)              If the aggregate number of Offer Securities that would be issued in consideration for all Company Shares with respect to which a Share Election was made is greater than the product of (x) the Total Share Elections Available and (y) the Acceptance Fraction, then:

(A)                               all Cash Election Shares and No Election Shares shall be exchanged for the Cash Consideration;

(B)                               the Exchange Agent shall then select from among the Share Election Shares, by a pro rata selection process, a sufficient number of shares, which shall be treated as Cash Election Shares (such shares being the “Cash Consideration Designated Shares”) such that the aggregate number of Offer Securities that will be issued equals as closely as practicable a number of Offer Securities equal to the product of (x) the Total Share Elections Available and (y) the Acceptance Fraction, and all Cash Consideration Designated Shares shall be exchanged for the right to receive the Cash Consideration; and

(C)                               the Share Election Shares that are not Cash Consideration Designated Shares shall be exchanged for the right to receive the Share Consideration;

(iii)           In the event that neither clause 1.3(b)(i) nor clause 1.3(b)(ii) is applicable,

(A)                               (1) all Cash Election Shares shall be exchanged for the Cash Consideration and (2) all Share Election Shares shall be exchanged into the right to receive the Share Consideration; and

(B)                               subsequent to the allocation by the Exchange Agent of consideration pursuant to clause 1.3(b)(iii)(A), all holders of No Election Shares shall be entitled to receive the Cash Consideration and the Share Consideration in proportion to the respective Total Cash Available and respective Total Share Elections Available, and to the extent there is no Total Cash Available or no Total Share Elections Available, in each case, reduced by a fraction equal to the Acceptance Fraction, such holders shall receive such consideration as remains available.

(c)                                  The pro rata selection process to be used by the Exchange Agent shall consist of such equitable pro ration processes as shall be mutually and reasonably determined by AMEC and the Company;

(d)                                In connection with any Subsequent Offering Period initiated by AMEC pursuant to clause 2.2, AMEC shall cause the Exchange Agent to effect the allocation of rights to receive Share Consideration or Cash Consideration among the holders of the Company Shares that validly tender such Company Shares on each day of such Subsequent Offering Period in accordance with the procedures provided in clause 1.3 above, provided that the Acceptance Fraction for each day of such Subsequent Offering Period shall be the fraction, expressed as a percentage, equal to (x) the total number of Company Shares tendered on the relevant day of such Subsequent Offering Period over (y) the total issued and to be issued Company Shares immediately prior to the Offer;

3

(e)                                  In no event shall the aggregate Cash Consideration paid in the Offer be greater than the Total Cash Consideration, nor the aggregate Share Consideration issued in the Offer be greater than the Total Share Elections Consideration.

1.4                               In accordance with the Timetable, AMEC will prepare and file a registration statement on (i) Form F-4 with the SEC to register the Offer Securities to be issued in connection with the Offer and (ii) Form F-6 registering the ADSs issuable upon deposit of the Offer Securities registered on the Form F-4 (such Form F-4 and Form F-6, together with any amendments, supplements and exhibits thereto, the “Registration Statements”). The Registration Statement on Form F-4 will include a preliminary prospectus containing the information required under Rule 14d-4(b) under the Exchange Act (the “Preliminary Prospectus”), the AMEC Circular, the AMEC Prospectus and the Company Proxy Statement. The Company will be given a reasonable opportunity to review and comment on the Registration Statements prior to filing with the SEC. AMEC shall use all reasonable endeavours to have the Registration Statements declared effective by the SEC as promptly as reasonably practicable after the filing thereof with the SEC and to keep the Registration Statements effective as long as is necessary to consummate the Offer and the transactions contemplated by this Agreement. Following the time that the Registration Statement on Form F-4 is declared effective, AMEC shall file the final prospectus included therein under Rule 424(b) of the Securities Act. AMEC shall (a) ensure that the Registration Statements, Preliminary Prospectus and the final prospectus referred to above comply in all material respects as to form with the applicable requirements of the Securities Act, the Exchange Act and all other applicable Laws, (b) cause the Registration Statements, the Preliminary Prospectus and the final prospectus referred to above to be disseminated to the Company Shareholders as an Offer Document to the extent required by applicable Laws, and (c) advise the Company of the time when the Registration Statements have become effective, of the issuance of any stop order with respect to the Registration Statements or the suspension of any qualification of the ADSs.

1.5                               In accordance with the Timetable, AMEC shall use all reasonable endeavours to obtain the approval of the UK Listing Authority in relation to the AMEC Circular and AMEC Prospectus and issue the AMEC Circular (together with the relevant forms of proxy) and AMEC Prospectus to the AMEC Shareholders and others entitled to receive the same, in each case in accordance with (as to both issuance and content) applicable Laws.

1.6                               In accordance with the Timetable, AMEC shall, or shall cause any direct wholly-owned subsidiary making the Offer to, commence the Offer and file the Schedule TO with the SEC and cause the Offer Documents to be disseminated to the Company Shareholders as and to the extent required by applicable Laws (including the Exchange Act). The Schedule TO shall contain, or incorporate by reference, the Preliminary Prospectus, the offer to purchase and forms of the related letter of transmittal, summary advertisement, notices to brokers, dealers and clients, and all other ancillary documents with respect to the Offer (collectively, together with all amendments, supplements and exhibits thereto, the “Offer Documents”), and AMEC shall ensure that the Offer Documents comply in all material respects as to form with the requirements of the Securities Act, the Exchange Act, the applicable rules and regulations of the NASDAQ Stock Market and all other applicable Laws.

1.7                               In accordance with the Timetable, on the date the Offer Documents are filed with the SEC (or as soon as practicable thereafter), the Company shall file with the SEC and disseminate to the Company Shareholders as and to the extent required by the Exchange Act, a Tender Offer Solicitation/Recommendation Statement on Schedule 14D-9 with respect to the Offer (together with any amendments and supplements thereto, the “Schedule 14D-9”) that shall reflect, subject to clause 6.2, the Company Recommendation.  The Company shall ensure that the Schedule 14D-9 complies in all material respects as to form with the requirements of the Exchange Act, the applicable rules and regulations of the NASDAQ

4

Stock Market and all other applicable Laws.  Subject to clause 6.2, the Company consents to the inclusion of the Company Recommendation in the Offer Documents and to inclusion of a copy of the Schedule 14D-9 with the Offer Documents mailed or furnished to the Company Shareholders.  As soon as reasonably practicable after the Company Proxy Statement is cleared by the SEC, the Company shall mail the Company Proxy Statement to the Company Shareholders and others entitled to receive the same.

1.8                               In accordance with the Timetable, AMEC will prepare and submit to a National Securities Exchange an application covering the ADSs being issued in the Offer and will use all reasonable endeavours to cause the ADSs to be approved for listing (subject to notice of issuance) for trading on such National Securities Exchange at or prior to the Offer Closing.  Except for procedures of the applicable clearing and settlement system and other customary limitations applicable to American depositary receipt programs for a public listed company incorporated in England and Wales with its primary listing on the LSE which will be disclosed in (or incorporated by reference into) the Registration Statements, the ADSs will have the same rights and privileges as the AMEC Shares, and will entitle the holder thereof to receive (upon deposit of ADSs with the depositary for cancellation, and payment of any applicable fees, charges and Taxes) the corresponding number of AMEC Shares.

1.9                               AMEC reserves the right to waive, in whole or in part, any Condition, to increase the Offer Price or to make any other changes to the terms and conditions of the Offer as it may determine in its sole discretion; provided, however, that, without the prior written consent of the Company, AMEC shall not:

(a)                                 reduce the number of Company Shares subject to the Offer;

(b)                                 reduce the Offer Price (or alter the cash or share components thereof described in clause 1.2, other than as expressly contemplated by clause 1.3);

(c)                                  amend, modify or waive the Minimum Tender Condition below 66 2/3 per cent.;

(d)                                 amend, modify or waive (i) the UK Listing Condition, (ii) the SEC Registration Condition or (iii) the US Listing Condition;

(e)                                  add to the Conditions or amend, modify or supplement any Condition in any manner adverse to the Company or the Company Shareholders in the context of the implementation of the Acquisition;

(f)                                   except as expressly provided in clause 2, terminate, extend or otherwise amend or modify the Expiration Time;

(g)                                  change the form of consideration payable pursuant to the Offer, except as otherwise determined by clause 1.3; or

(h)                                 otherwise amend, modify or supplement any of the terms of the Offer in a manner which is adverse to the Company or the Company Shareholders (other than to an extent which is not material).

1.10                        Subject only to the satisfaction or waiver of the Conditions, AMEC shall, or shall cause any direct wholly-owned subsidiary making the Offer to, consummate the Offer in accordance with its terms and applicable Laws, and shall accept for payment and pay for all Company Shares validly tendered and not withdrawn pursuant to the Offer promptly after the Expiration Time (or, in the case of Company Shares so validly tendered during a Subsequent Offering Period, promptly after such Company Shares are tendered) and in any event in compliance with Rule 14d-10 and Rule 14e-1(c) under the Exchange Act.  The Cash

5

Consideration shall be paid to each Company Shareholder in cash and the Share Consideration shall be paid to each Company Shareholder in validly issued Offer Securities pursuant to the terms and conditions of this Agreement and the Offer Documents.  The Offer Price shall be equitably adjusted to the extent appropriate to reflect the effect of any of the following transactions with respect to either AMEC or the Company and their respective equity share capital:

(a)                                 stock split, division or subdivision, reverse stock split, consolidation or combination, reclassification, recapitalisation, repayment of capital, issuance of options, convertible securities and other rights for the issuance of equity share capital, capital increases, sale of treasury shares at a discount or any other similar transaction (in each case, save for, in relation to the Company: the grant of Company Awards under the Company Omnibus Plan in accordance with clause 8.4 and the satisfaction of Company Awards and Company Awards outstanding under the Company Omnibus Plan as at the date of this Agreement, and in relation to AMEC: the grant of AMEC Awards and AMEC Options and the satisfaction of AMEC Awards and AMEC Options outstanding under the AMEC Employee Share Plans as at the date of this Agreement); or

(b)                                 cash dividend or stock dividend or any other distribution of any kind (including any dividend or distribution of securities convertible into equity securities), in each case occurring or having a record date on or after the date of this Agreement and prior to the Expiration Time, save for and not including the Permitted ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Dividend (which, for the avoidance of doubt, shall not give rise to any adjustment to the Offer Price) or (subject to the next sentence) any Permitted AMEC Dividend. If the record date for the dividend referred to in (b) of the definition of “Permitted AMEC Dividend” (the “Second Record Date”) is prior to the Expiration Time, then (i) the terms of the Offer shall be amended by AMEC (or AMEC shall procure they are amended) such that the Total Cash Consideration is increased by the amount of the dollar equivalent on the Second Record Date of the amount of such dividend per AMEC Share multiplied by the Total Share Elections Consideration (the “Additional Entitlement”) and the Cash Consideration shall be increased by the dollar equivalent (on such record date) of the amount of such dividend multiplied by 0.8998, or (ii) if ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ elects in writing at least five (5) Business Days prior to the Second Record Date, ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ shall be entitled to pay an additional cash dividend (“Additional ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Dividend”) equal in aggregate to the Additional Entitlement.  AMEC agrees that the Second Record Date shall not fall between the Expiration Date and the date of issuance of Offer Securities in respect of Company Shares accepted for exchange in the Offer. AMEC will not change the Second Record Date from 28 November 2014 without giving at least ten (10) Business Days notice to the Company.

The Company agrees that no Company Shares held by the Company or any of its subsidiaries will be tendered pursuant to the Offer or sold or otherwise disposed of or in any way encumbered after the date hereof, and that no Company Shares will be purchased by the Company or any of its subsidiaries, except in connection with the satisfaction of existing entitlements under the Company Omnibus Plan.

1.11                        No fractional Offer Securities will be issued in the Offer to any Company Shareholder. Notwithstanding any other provision of this Agreement, each Company Shareholder who would otherwise have been entitled to receive a fraction of an Offer Security (after aggregating each of all fractional ADSs and all fractional AMEC Shares issuable to such Company Shareholder in the Offer) shall receive from the Exchange Agent, in lieu thereof, cash (without interest) in an amount representing such Company Shareholder’s

6

proportionate interest in the net proceeds from the sale by the Exchange Agent on behalf of all such Company Shareholders of the aggregate number of ADSs or AMEC Shares, as appropriate, which would otherwise be issued (the “Excess ADSs” and “Excess AMEC Shares”, respectively). The sale of all the Excess ADSs by the Exchange Agent shall be executed on a National Securities Exchange, through one or more member firms of such National Securities Exchange, and the sale of all of the Excess AMEC Shares shall be executed on the LSE, through one or more member firms of the LSE, and each shall be executed in round lots to the extent practicable. Until the net proceeds of such sales have been distributed to the Company Shareholders, the Exchange Agent shall hold such proceeds in trust absolutely for such Company Shareholders (the “Fractional Interests Trust”). AMEC shall pay all commissions, transfer taxes and other out-of-pocket transaction costs incurred in connection with such sale of the Excess ADSs and Excess AMEC Shares. The Exchange Agent shall determine the portion of the Fractional Interests Trust to which each Company Shareholder shall be entitled, if any, by multiplying the amount of the aggregate net proceeds comprising the Fractional Interests Trust by a fraction, the numerator of which is the amount of fractional interests to which such Company Shareholder is entitled and the denominator of which is the aggregate amount of fractional interests to which all Company Shareholders are entitled. As soon as practicable after the determination of the amount in cash, if any, to be paid to Company Shareholders in lieu of fractional interests, the Exchange Agent shall make available such amounts to such Company Shareholders. Any such sale shall be made within ten (10) Business Days or such shorter period as may be required by applicable Laws after the Expiration Time (or, in the case of Company Shares validly tendered during a Subsequent Offering Period, after the expiration thereof).  AMEC and the Company acknowledge that payment of cash consideration in lieu of issuing fractional ADSs or AMEC Shares was not separately bargained for consideration but represents merely a mechanical rounding-off for purposes of simplifying complications that could otherwise be caused by the issuance of fractional shares of ADSs or AMEC Shares.

1.12                        AMEC and the Company shall enter into an Exchange Agency Agreement with the Exchange Agent (the “Exchange Agency Agreement”), which agreement shall set forth the duties, responsibilities and obligations of the Exchange Agent consistent with the terms of this Agreement.  By no later than the Offer Closing, AMEC shall deposit with the Exchange Agent cash in an amount equal to the cash payable at the Offer Closing pursuant to clause 1.3 and shall subsequently deposit with the Exchange Agent cash in an amount equal to the cash payable in any Subsequent Offering Period pursuant to clause 1.3. By no later than the Offer Closing, AMEC shall allot and issue to each holder of Company Shares who has surrendered Company Shares the number of Offer Securities to be allotted and issued to such person pursuant to clause 1.3 and shall subsequently allot and issue to each holder of Company Shares in any Subsequent Offering Period who has surrendered Company Shares the number of Offer Securities to be allotted and issued to such person pursuant to clause 1.3. The Offer Securities will be issued fully paid and free from all liens, charges, equitable interests, encumbrances, rights of pre-emption and other third party rights of any nature whatsoever and together with all rights attaching to them. The Offer Securities will rank equally in all respects with the existing AMEC Shares, including the right to receive all dividends and other distributions declared, made or paid by AMEC by reference to a record date falling on or after the issuance thereof.

1.13                        AMEC shall be entitled to deduct and withhold from the consideration otherwise payable in respect of the Company Shares such amounts as it is required to deduct and withhold with respect to the making of such payment under any applicable Tax Law.  To the extent that amounts are so withheld by AMEC, such withheld amounts shall be treated for all purposes of this Agreement and the Offer as having been paid to the Company Shareholder in respect of which such deduction and withholding was made by AMEC.

7

2.                                      OFFER PERIOD

2.1                               The Offer shall expire at 11:59 p.m., New York City time, at the end of the twentieth (20th) Business Day following the commencement (for this purpose calculated in accordance with Rule 14d-1(g)(3) under the Exchange Act) of the Offer (the “Initial Expiration Time”).

2.2                               Notwithstanding anything else to the contrary in this Agreement:

(a)                                 if, at the Initial Expiration Time or any subsequent scheduled expiration of the Offer, any Condition shall not have been satisfied or waived, AMEC shall extend the Offer on one or more occasions, in consecutive increments of up to ten (10) Business Days (or such other period as the parties hereto may agree) each, until such time as all of the Conditions shall have been satisfied (or, to the extent permitted, waived); and

(b)                                 without prejudice to clause 2.2(a), AMEC shall extend the Offer for the minimum period required by any rule, regulation, interpretation or position of the SEC or the staff thereof or of a National Securities Exchange, or any other applicable Laws,

provided, however, that (i) AMEC shall (to the extent clause 2.2(a) does not already so provide) on a single occasion cause the Offer to be extended for a five (5) Business Day period following the first date on which all Conditions other than the Minimum Tender Condition are satisfied or waived (and, as required, the Longstop Date shall be extended through such five (5) Business Day period) and (ii) in each case, AMEC shall not be required to extend the Offer beyond the Longstop Date, except as the Longstop Date is extended in accordance with the definition thereof or pursuant to sub-clause (i) of this proviso (it being agreed and understood that if the Longstop Date is extended in accordance with the definition thereof, the provisions of this clause 2.2 (including sub-clause (i) of this proviso) shall continue to apply and the Offer shall be extended accordingly). The Initial Expiration Time or, in the event the Initial Expiration Time has been extended pursuant to this Agreement (other than in connection with a Subsequent Offering Period as described in the following sentence), the date and time to which the Offer has been so extended is referred to herein as the “Expiration Time”. For the avoidance of doubt, AMEC shall have the right to (and shall upon the Company’s reasonable request), following the Offer Closing, extend the Offer for a reasonable “subsequent offering period”, in accordance with Rule 14d-11 under the Exchange Act and to the extent permissible under applicable Law (such period the “Subsequent Offering Period”). AMEC shall comply (subject to applicable Law) with any reasonable request from the Company as to the length of such Subsequent Offering Period to take into account the need for Company optionholders to have a reasonable opportunity to tender into the Offer.

2.3                               AMEC shall not, and shall not permit any wholly-owned subsidiary making the Offer to, terminate the Offer prior to the Expiration Time without the prior written consent of the Company except in the event that this Agreement is validly terminated pursuant to clause 15.  If this Agreement is validly terminated in accordance with clause 15, the Offer shall be terminated and AMEC shall promptly return, and shall cause any depository acting on behalf of AMEC to return, all tendered Company Shares to the registered holders thereof.

3.                                      SATISFACTION OF THE CONDITIONS AND OTHER CLEARANCES

3.1                               Unless and until this Agreement is validly terminated in accordance with clause 15 (and without prejudice to the additional covenants and agreements set forth herein), each party shall, in accordance with the terms and conditions herein, use all reasonable endeavours to achieve satisfaction of the Conditions as promptly as practicable and to implement the Acquisition and each stage thereof in accordance with the Timetable.

8

3.2                               With respect to the Antitrust Clearances that are required for the satisfaction of the Conditions, it is agreed that:

(a)                                 without prejudice to clause 3.3 or the other provisions of this clause 3.2, the parties shall use all reasonable endeavours to procure that Condition 2 is fulfilled as soon as reasonably practicable after the date of this Agreement;

(b)                                 the parties shall cooperate with each other in order to allow for AMEC, the Company or AMEC and the Company jointly, as may be required, to make the necessary filings as soon as reasonably practicable and, in any event, in accordance with the Timetable, and to ensure that all information necessary or desirable for the making of (or responding to any requests for further information and other enquiries) any filings (including draft versions) is supplied accurately, promptly, diligently and to the best of each party’s ability or knowledge and is not intentionally misleading or incomplete;

(c)                                  each party shall:

(i)                   commence any pre-notification processes, as applicable, in respect of the filings required to satisfy Condition 2 as soon as reasonably practicable following the date of this Agreement with such filings to be made as promptly as is reasonably practicable thereafter in accordance with clause 3.2(b) (and for the avoidance of doubt, in accordance with clause 17, all AMEC’s costs and expenses (including all filing fees) in relation to such filings shall be borne by AMEC);

(ii)                promptly notify the other party’s external counsel sufficiently in advance of any notification, submission, response or other communication (excluding communications of an administrative nature) which it proposes to make or submit to any Relevant Antitrust Authority and at the same time provide the other party’s external counsel with copies thereof and any supporting documentation or information reasonably requested by the other party’s external counsel; provided, however, that nothing in this clause 3.2 shall require AMEC to provide the Company with any confidential information or business secrets;

(iii)            subject to clause 3.2(c)(ii), on reasonable request, provide the other party with information and documents relating to its business, as well as reasonable access to its management and employees, both to the extent reasonably necessary or desirable to facilitate the parties’ ability to satisfy Condition 2, provided that such information, documents and access is provided diligently and to the best of each party’s ability or knowledge and is not intentionally misleading or incomplete;

(iv)           provide the other party with a reasonable opportunity to provide comments on drafts of any filings or other material documentation prior to their submission to the Relevant Antitrust Authority and consider and take due consideration of such comments prior to submitting any filing or other material documentation to the Relevant Antitrust Authority (it being acknowledged that certain such drafts and/or documents may be shared on a confidential outside counsel to counsel basis only);

(v)              submit no filings or other material documentation to a Relevant Antitrust Authority in relation to a filing made jointly by AMEC and the Company without reasonably considering the views of the other party;

9

(vi)           not, without reasonably considering the views of the other party, withdraw a filing made to the Relevant Antitrust Authority;

(vii)        give the other party and its advisers reasonable notice of and reasonable opportunity to participate, where appropriate, in all meetings, and material communications and material conferences with the Relevant Antitrust Authority to the extent not prohibited by applicable Laws;

(viii)     respond as soon as reasonably practicable to all inquiries received from the Relevant Antitrust Authority for additional information or documentation and supplement such filings as reasonably requested by the Relevant Antitrust Authority, and to keep the other party informed of material contact with the Relevant Antitrust Authority and, to the extent not prohibited by applicable Laws, provide the other party with copies of all material relevant documentation in relation thereto (to the extent such information relates to the party’s Group); and

(ix)           notify the other party within two (2) Business Days after receipt of each such Antitrust Clearance required to satisfy Condition 2 and provide such information as the other party may reasonably require in respect of the satisfaction of such Condition.

3.3                               AMEC, in order to satisfy or procure the satisfaction of Condition 2, shall be obliged to use all reasonable endeavours to implement or satisfy, or agree to implement or satisfy, any disposals, conditions, obligations, terms or undertakings and take all other reasonable steps that may be required, or imposed or proposed by a Relevant Antitrust Authority, as a basis for that Relevant Antitrust Authority giving its consent to, or clearance for, the Acquisition (collectively, “Remedies”) where any such Remedy is required in order to ensure that Condition 2 is fulfilled before the Longstop Date. Notwithstanding anything in this Agreement to the contrary, AMEC shall not be required to license, sell, divest, transfer or dispose of, or to agree to license, sell, divest, transfer or dispose of, any of its (or of its affiliates’) or any of the Company’s (or any of its affiliates’) assets (including any contract rights), shareholdings, businesses, licenses or personnel to the extent that the revenues generated by, or attributable to, any and all such asset(s), shareholding(s), business(es), license(s) or personnel were in excess of $200,000,000 in aggregate in the fiscal year ended on 31 December 2013 (the loss of such amount of revenues to be considered a “Material Adverse Impact”). Nor shall AMEC and/or the Company be required to commit to any behavioural commitments or restrictions that in aggregate and together with any Remedy or Remedies, would be reasonably likely to have a Material Adverse Impact on any of AMEC’s (or of its affiliates’) and/or the Company’s (or of its affiliates’) businesses, considered separately or together.  Nor shall AMEC and/or the Company be required as a condition of CFIUS Approval to consent to any mitigation agreement or condition that would deprive AMEC of functional control, including the ability to direct business operations, enter into or terminate contracts, and appoint or dismiss a majority of directors, officers, or senior managers, of any of its (or any of its affiliates) or the Company’s (or any of its affiliates’) US assets.

3.4                               Each party undertakes to the other party to cooperate using all reasonable endeavours in relation to obtaining any and all Additional Antitrust Clearances and other Clearances and satisfying any and all obligations in connection with the Acquisition as promptly as practicable and in particular (to the extent that such steps have not already been taken prior to the date hereof and to the extent permissible under applicable Laws):

(a)                                 to make as promptly as reasonably practicable and, in any event, in accordance with the Timetable and within any relevant time limit, all such filings with any appropriate

10

Governmental Authorities, jointly or separately, as are necessary or desirable for the purposes of obtaining such Additional Antitrust Clearances and other Clearances;

(b)                                 to provide as promptly as practicable, in consultation with the other party, such information and assistance as may be reasonably requested by a Governmental Authority or by a party making a filing to a Governmental Authority in connection with such Additional Antitrust Clearances and other Clearances; and

(c)                                  to promptly notify the other party of, and provide copies of, any material communications with a Governmental Authority in connection with the obtaining of such Additional Antitrust Clearances and other Clearances, save in respect of any information the disclosure of which would, in the reasonable opinion of the party concerned, adversely affect its legitimate business interests.

3.5                               Each party undertakes to keep the other informed reasonably promptly of developments which are material or potentially material to the obtaining of the Antitrust Clearances, Additional Antitrust Clearances or other Clearances which would materially affect the implementation of the Acquisition (other than the matters contemplated by clause 11, which shall be governed by clause 11, the other provisions hereof that relate to clause 11 or that are referred to in clause 11).

4.                                      SQUEEZE-OUT

4.1                               As soon as reasonably practicable after the Offer Closing Date (or such other date agreed in writing by AMEC and the Company) and provided that (i) at such time AMEC directly or indirectly has acquired or controls at least 90 per cent. of the issued Company voting rights, (ii) no actions or proceedings are pending with respect to the exercisability of voting rights with respect to Company Shares acquired or controlled by AMEC and (iii) no other legal impediment to the launch or consummation of the Squeeze-Out Merger (as defined below) then exists (sub-clauses (i), (ii) and (iii), the “Squeeze-Out Prerequisites”), AMEC shall cause an eligible legal entity that is a wholly-owned subsidiary of AMEC organised under Swiss Law that is treated as disregarded as an entity separate from AMEC for US federal Tax purposes (“MergeCo”) to, propose to the Company to merge the Company with and into MergeCo (with MergeCo being the surviving entity in such merger) and to launch a squeeze-out merger pursuant to articles 8 para 2 and 18 para 5 of the Merger Act (the “Squeeze-Out Merger”), whereby the then-remaining Company Shareholders (other than the Company and its affiliates) would receive compensation pursuant to article 8 para 2 of the Merger Act as consideration for their outstanding Company Shares (the “Squeeze-Out Offer”); provided, that if a subsidiary of AMEC has made the Offer, then such subsidiary shall be treated, or shall have validly elected to be so treated from the date of its formation, as disregarded as an entity separate from AMEC for US federal Tax purposes.

4.2                               Subject to applicable Laws and the satisfaction of the Squeeze-Out Prerequisites, AMEC shall use all reasonable endeavours to:

(a)                                 cause the Acquisition to qualify for US federal income tax purposes as a reorganization within the meaning of Section 368(a) of the Code and will not take any action for the purpose of causing the Acquisition not so to qualify; and

(b)                                 cause this Agreement to constitute a “plan of reorganization” for the purposes of Sections 354, 361 and 368 of the Code.

4.3                               For the avoidance of doubt, nothing in this Agreement (including the obligations of AMEC under clauses 4.1 and 4.2):

11

(a)                                 shall oblige AMEC to pay aggregate consideration to acquire all of the issued and to be issued Company Shares (whether pursuant to the Offer, any Squeeze-Out Merger, or otherwise) greater than the Total Cash Consideration and the Total Share Elections Consideration;

(b)                                 shall restrict AMEC from acquiring any Company Shares not tendered into the Offer using such form of consideration as may be necessary to acquire such Company Shares; or

(c)                                  shall oblige AMEC to incur any Taxes or other expenditure (other than advisers’ fees or other immaterial expenditure) in satisfying its obligations under clauses 4.1 and 4.2.

5.                                      OBLIGATIONS OF THE PARTIES

5.1                               Subject to clause 5.11, AMEC shall:

(a)                                 once approved by the UK Listing Authority, and save as may be required by applicable Laws or any Governmental Authority (including but not limited to the UK Listing Authority), not seek to revise, alter or modify the AMEC Circular (including the AMEC Resolution and, subject to clause 6.4, the AMEC Recommendation, each contained therein) or the AMEC Prospectus in a manner which is adverse to the Company or the Company Shareholders (save to the extent that such revision, alteration or modification is not material) without the Company’s written approval (not to be unreasonably withheld or delayed);

(b)                                 prior to the AMEC General Meeting and subject to applicable Laws, keep the Company informed, on a regular basis or as soon as reasonably practicable following each request from the Company, of the number of proxy votes received in respect of the AMEC Resolution and of any communications received by AMEC or its representatives or advisers indicating that a shareholder beneficially holding 1 per cent. or more of AMEC’s issued share capital is proposing to vote against, or withhold its vote on, the AMEC Resolution;

(c)                                  if requested in writing by the Company prior to the date of the AMEC General Meeting, promptly after the date of such request, take reasonable steps (subject to applicable Laws) to encourage AMEC Shareholders to vote in favour of the AMEC Resolution (including engaging a proxy solicitation agent to contact AMEC Shareholders and encourage them to duly complete and return forms of proxy);

(d)                                 subject to clause 5.2, in accordance with applicable Laws and the Charter Documents of AMEC, convene the AMEC General Meeting and hold such AMEC General Meeting at the time and date specified in the AMEC Circular and propose the AMEC Resolution (such resolution to be voted on by way of a poll) without amendment; provided, however, the Company’s advisers and representatives shall be entitled to attend the AMEC General Meeting;

(e)                                  not propose any resolution or take any other action that would result in the revocation or invalidity of the AMEC Resolution such that the Acquisition cannot be implemented in accordance with its terms;

(f)                                   pay (or procure the payment of) the Due Amounts in accordance with the terms of this Agreement and the Offer Documents; and

12

(g)                                  as promptly as reasonably practicable and in accordance with the Timetable, prepare, publicise, distribute, file and submit any other Acquisition Documents.

5.2                               Subject to clause 6.4, AMEC agrees not to adjourn the AMEC General Meeting from the time and date specified in the AMEC Circular without the prior written consent of the Company (not to be unreasonably withheld or delayed) unless it is not reasonably practicable to seek such consent because the motion to adjourn is only moved at the AMEC General Meeting by AMEC Shareholders (other than the AMEC Directors).  Notwithstanding any provision of this Agreement to the contrary, AMEC may, in its sole discretion, adjourn, recess or postpone the AMEC General Meeting (a) after consultation with the Company, to the extent necessary to ensure that any required supplement or amendment to any Acquisition Document is provided to the AMEC Shareholders within a reasonable amount of time in advance of the AMEC General Meeting, (b) to the extent required by applicable Laws or any Governmental Authority or (c) if as of the time for which the AMEC General Meeting is originally scheduled (as set forth in the AMEC Circular) there are an insufficient number of AMEC Shares represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of the AMEC General Meeting or to the extent that at such time AMEC has not received proxies sufficient to allow the receipt of the AMEC Shareholder Approval at the AMEC General Meeting.  If the AMEC General Meeting is adjourned to another day than that for which it was originally convened, it shall be adjourned for as short a period as is reasonably practicable and permissible (or such longer period as the Company may agree in writing, such agreement not to be unreasonably withheld or delayed).  AMEC shall not induce or encourage any person to seek to adjourn the AMEC General Meeting.  The AMEC Resolution shall be submitted to the AMEC Shareholders at the AMEC General Meeting whether or not the AMEC Board shall have effected a Change of AMEC Recommendation.

5.3                               If so requested by AMEC, the Company undertakes to use, at the sole expense of AMEC and subject to clause 5.9, all reasonable endeavours prior to the Offer Closing Date in seeking (on terms approved in writing, or as reasonably requested, by AMEC) amendments to or waivers of those terms of any credit facility of the Company or its Group where any such credit facility becomes or may become required to be repaid, the subject of cash cover and/or cancelled (as applicable) as a result of the consummation of the Acquisition.

5.4                               Without prejudice to the other provisions of this Agreement, each of AMEC and the Company undertakes that it shall procure that each member of its Group (for the avoidance of doubt, including MergeCo following its formation) shall, as promptly as reasonably practicable:

(a)                                 comply with the obligations and restrictions set out in this Agreement that are expressed to be applicable to or relate to such member of its Group; and

(b)                                 use all reasonable endeavours to take or cause to be taken all such steps as are within such member of its Group’s power and reasonably necessary to implement the Acquisition in accordance with the Timetable.

5.5                               In connection with the Offer, the Company shall:

(a)                                 once cleared by the SEC, and save as may be required by applicable Laws or any other Governmental Authority, not seek to revise, alter or modify the Company Proxy Statement (or, subject to clause 6.2, the Company Recommendation contained therein) in a manner which is adverse to AMEC or the AMEC Shareholders (save to the extent that such revision, alteration or modification is not material) without AMEC’s written approval (not to be unreasonably withheld or delayed);

13

(b)                                 prior to the Company General Meeting and subject to applicable Laws, keep AMEC informed, on a regular basis or as soon as reasonably practicable following a request from AMEC, of the number of proxy votes received in respect of the Company Resolutions and of any communications received by the Company or its representatives or advisers indicating that a shareholder beneficially holding 1 per cent. or more of the Company’s issued share capital is proposing to vote against, or withhold its vote on, the Company Resolutions;

(c)                                  if requested in writing by AMEC prior to the date of the Company General Meeting, promptly after the date of such request, take reasonable steps (subject to applicable Laws) to encourage Company Shareholders to vote in favour of the Company Resolutions (including engaging a proxy solicitation agent to contact the Company Shareholders and encourage them to duly complete and return forms of proxy in favour of the Company Resolutions);

(d)                                 subject to clause 5.7, in accordance with applicable Laws and the Charter Documents of the Company, convene the Company General Meeting and hold such Company General Meeting (on a date after the AMEC General Meeting) at the time and date specified in the Company Proxy Statement and propose the Company Resolutions without amendment; provided, however, that AMEC’s advisers and representatives shall be entitled to attend the Company General Meeting;

(e)                                  if approved by the Company General Meeting and promptly upon satisfaction or waiver of all Conditions but for Condition 5, file for registration with the competent commercial register the amendments to the Company’s articles of association removing the transfer restrictions according to article 8 para. 5 and the voting limitations according to article 16 para. 3 and, in each case, related provisions of the articles of association of the Company, and procure the satisfaction of Condition 5 in accordance with the standard required in clause 3.1;

(f)                                   prior to the Offer Closing Date, convene and hold a Company Board meeting to resolve, and the Company Board shall resolve, to register AMEC and any of its affiliates (effective as of Offer Closing) in the Company’s share register as a shareholder with voting rights with respect to all Company Shares any of them has acquired or may acquire in the Offer subject to all Conditions other than Conditions 5 and 6 having been satisfied or waived; provided, however, that this shall not in any way limit any of the Company’s obligations under clause 5.5(e); and

(g)                                  procure that prior to the Company General Meeting, the Resigning Company Board Members resign from office with effect from the Offer Closing, the Remaining Company Board Members enter into — and do not subsequently terminate — a Mandate Agreement subject only to, and with effect from, the Offer Closing, and the Company shall file the Resigning Company Board Members’ resignation and, in furtherance of their election at the Company General Meeting, the New Company Board Members election for registration, with the competent commercial register immediately upon Offer Closing.

5.6                               Subject to the Offer Closing and subject to there having been no fraudulent behaviour, wilful misconduct and gross negligence of such Company Director or officer, AMEC undertakes that it shall, and it shall procure that its affiliates shall, at the relevant ordinary (annual) general meeting of shareholders, vote any Company Shares they each acquire in or outside of the Offer and for which they have been registered in the Company’s share register as shareholders with voting rights in favour of granting discharge (pursuant to article 698, para. 2, clause 5 of the Swiss Code of Obligations) to the Company Directors and officers for the period from the end of the Company’s last fiscal year (ending 31 December

14

2013) until the Offer Closing Date.  Subject to the Offer Closing, AMEC undertakes to pay or to cause its affiliates (including after Offer Closing, the Company) to promptly pay to each Company Director any and all amounts owing to such Company Director as at the Offer Closing Date.

5.7                               Subject to clause 6.2, the Company agrees not to adjourn the Company General Meeting from the time and date specified in the Company Proxy Statement without the prior written consent of AMEC (not to be unreasonably withheld or delayed) unless it is not reasonably practicable to seek such consent because the motion to adjourn is only moved at the Company General Meeting by Company Shareholders (other than the Company Directors). Notwithstanding any provision of this Agreement to the contrary, the Company may, in its sole discretion, adjourn, recess or postpone the Company General Meeting (a) after consultation with AMEC, to the extent necessary to ensure that any required supplement or amendment to the Company Proxy Statement is provided to the Company Shareholders within a reasonable amount of time in advance of the Company General Meeting, (b) to the extent required by applicable Laws or any Governmental Authority, (c) to the extent that the AMEC General Meeting is adjourned or postponed, or (d) if as of the time for which the Company General Meeting is originally scheduled (as set forth in the Company Proxy Statement) there are an insufficient number of Company Shares represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of the Company General Meeting or to the extent that at such time the Company has not received proxies sufficient to allow the receipt of the Company Shareholder Approval at the Company General Meeting. If the Company General Meeting is adjourned to another day than that for which it was originally convened, it shall be adjourned for as short a period as is reasonably practicable and permissible (or such longer period as AMEC may agree in writing, such agreement not to be unreasonably withheld or delayed). The Company shall not induce or encourage any person to seek to adjourn the Company General Meeting.  The Company Resolutions shall be submitted to the Company Shareholders at the Company General Meeting whether or not the Company Board shall have effected a Change of Company Recommendation.

5.8                               The Company undertakes to use all reasonable endeavours to provide, at the sole expense of AMEC, all assistance as may be reasonably requested by AMEC in connection with the Financing Document including, without limitation, assisting AMEC with AMEC’s efforts to obtain long-term corporate credit ratings from Standard & Poor’s Ratings Services and ▇▇▇▇▇’▇ Investors Service Limited and assisting AMEC by providing any documentation and other evidence reasonably requested by AMEC to comply with the “know your customer” or other similar checks required in connection with the Financing Document; and providing to AMEC all such information about itself and its subsidiaries as may be reasonably requested from the Company by AMEC in relation thereto, provided, however, that nothing herein shall require such cooperation to the extent it would:

(a)                                 interfere unreasonably with the business or operations of any member of the Company Group;

(b)                                require any member of the Company Group to take any action that will conflict with or violate its Charter Documents or any Laws or result in the contravention of, or that would reasonably be expected to result in a violation or breach of, or default under, any material contract to which it is a party; or

(c)                                  require any member of the Company Group to approve or enter into definitive credit documentation in relation to any financing that would be effective prior to the Offer Closing Date.

15

5.9                               AMEC shall indemnify and hold harmless each Company Relevant Person from and against any and all liabilities, losses, damages, claims, costs, expenses, interest, awards, judgments and penalties suffered or incurred by them in connection with the arrangement of debt financing under the Financing Document, including any action taken in accordance with clauses 5.3 or 5.8 and any information utilised in connection therewith in each case prior to the Offer Closing Date, except to the extent that such liabilities, losses, damages, claims, costs, expenses, interest, awards, judgments and penalties arise out of or in connection with the gross negligence, wilful misconduct, bad faith or fraud by such Company Relevant Person.

5.10                        Each party undertakes to use all reasonable endeavours to provide such assistance to the other party as may be reasonably requested by the other party for the preparation of the Acquisition Documents to be prepared by the other party (including, without limitation, the preparation of the Schedule 14D-9) including, without limitation, providing, all such information about itself and its subsidiaries as may be reasonably requested, including constitutional documents, financial statements, pro formas, reconciliations, information required to prepare working capital reports and verification notes with respect to information to be included in the Acquisition Documents to be prepared by the other party, including access to, and ensuring the provision of reasonable assistance by, its management or relevant professional advisers.

5.11                        Each party and its respective advisers shall be given a reasonable opportunity to review and comment on drafts of each Acquisition Document that has been prepared by, or that is required to be filed, published or distributed by, the other party prior to filing, publication or distribution thereof. Each party shall procure that all drafts of Acquisition Documents prepared by it, or that it is required to file, publish or distribute, are provided to the other party and its advisers and the parties shall cooperate and consult in good faith with each other and consider, in good faith, the comments of the other party and its advisers in relation to each Acquisition Document.  Without prejudice to the foregoing, to the extent that any Acquisition Document that has been prepared by, or that is required to be filed, published or distributed by, (a) AMEC, contains Company Information, or (b) the Company, contains AMEC Information, such party will seek the approval of the other party (such approval not to be unreasonably withheld or delayed) in relation to such information in the content of the relevant Acquisition Document and afford the other party sufficient time to consider such information in order to give its approval.

5.12                        AMEC shall provide the Company and its advisers with any comments, whether written or oral, that AMEC or its advisers may receive from time to time from the SEC or the UK Listing Authority or the LSE, or any of their respective staff, with respect to the Registration Statements, the Offer Documents or the Acquisition Documents, and the Company shall provide AMEC and its advisers with any comments, whether written or oral, that the Company may receive from time to time from the SEC or its staff with respect to the Schedule 14D-9 or the Company Proxy Statement. Each of the parties shall use all reasonable endeavours to resolve, and each party agrees to consult and cooperate with the other party in resolving, all such comments as promptly as practicable after receipt thereof. Promptly after a party’s receipt of any such comments, such party shall promptly consult with the other party and its advisers prior to responding to any such comments and provide the other party with copies of all such written responses (or if oral responses, summaries thereof).

5.13                        Each party hereto shall ensure that none of the information it supplies or has supplied for inclusion or incorporation by reference in any Acquisition Document, at the time such document is filed with the SEC or the UK Listing Authority, at any time it is amended or supplemented or at the time it is first published, contains any untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading in any material respect. Each party shall promptly notify the

16

other party if any of the information supplied by it contains such a misstatement or omission, or otherwise has become false or misleading in any material respect, and shall supply such information to the other party as shall be necessary to correct the misstatement or omission. Without limiting the foregoing, whenever any party hereto becomes aware of any event or change which is required to be set forth in an amendment or supplement to an Acquisition Document in respect of which either party has filing or preparation responsibility hereunder (including as a result of a misstatement or omission of the kind described in the immediately preceding sentence), as applicable, such party shall promptly inform the other party thereof and shall take all such action, with the cooperation of the other party, to prepare, file with the relevant Governmental Authority and/or (as and to the extent required by applicable Laws), disseminate to the Company Shareholders and/or AMEC Shareholders (as the case may be) such amendment or supplement (including to correct such misstatement or omission), which filing and dissemination shall be made and done, as promptly as practicable.

5.14                        Between the date of this Agreement and the Offer Closing Date, each of the parties to this Agreement shall promptly notify the other party in writing if it becomes aware of the occurrence of any material breach of any of its covenants in this Agreement or of the occurrence of any event that may make the satisfaction of any Condition impossible or reasonably unlikely.  The delivery of any notice pursuant to this clause 5.14 shall not (a) cure any breach of, or non-compliance with, any other provision of this Agreement or (b) limit the remedies available to the party receiving such notice.

5.15                        The Company shall give prompt notice to AMEC, and AMEC shall give prompt notice to the Company, of any suit, claim, action or proceeding commenced or, to such party’s knowledge, threatened against, relating to or involving or otherwise affecting such party or any of its subsidiaries which relate to the Offer, the Company Resolutions, the AMEC Resolution or the transactions contemplated by this Agreement. Without limiting the foregoing, in the event that any shareholder or derivative action related to this Agreement, the Offer, the Company Resolutions (in the case of the Company), the AMEC Resolution (in the case of AMEC) or the transactions contemplated by this Agreement is brought, or, to the knowledge of the applicable party, threatened in writing (it being agreed and understood that law firm press releases and other similar general communications to the public shall not constitute a threat in writing for the purposes hereof), against a party and/or the members of the Company Board (in the case of the Company) or the AMEC Directors (in the case of AMEC) prior to the Offer Closing Date, the party against which such action is brought or threatened shall promptly notify the other party of any such suit, claim, action or proceeding or threat and shall keep the other party reasonably informed with respect to the status thereof. The notifying party shall reasonably consult with the other party with respect to the defence or settlement of any such action or threat, and no settlement thereof shall be agreed to without such other party’s prior written consent (not to be unreasonably withheld, delayed or conditioned).

6.                                      BOARD APPROVALS AND RECOMMENDATIONS

6.1                               The Company confirms that the Company Board has by way of a unanimous board resolution (a) determined that this Agreement and the Offer are in the best interests of the Company and fair to Company Shareholders, (b) approved this Agreement, and (c) resolved to recommend to the Company Shareholders acceptance of the Offer.  Subject to clause 6.2, the Company agrees that the relevant Offer Documents requiring such disclosure shall incorporate a recommendation from the Company Board to the Company Shareholders to accept the Offer (the “Company Recommendation”).

6.2                               The Company further undertakes that it will not at any time make any Change of Company Recommendation, except to the extent that a majority of the Company Directors has determined in good faith (having taken appropriate financial and legal advice) (i) in the

17

case of a Change of Company Recommendation relating to a Competing Proposal, that such Competing Proposal is or is reasonably likely to constitute a Superior Proposal, or (ii) in any other case, that it is necessary to do so in order for the Company Directors to comply with their fiduciary duties and provided that the Company shall notify AMEC as soon as reasonably practicable of any Change of Company Recommendation.  For the avoidance of doubt, it is agreed and understood that any “stop, look and listen” or similar commitments of the type contemplated by Rule 14d-9(f) of the Exchange Act shall not be deemed to be a Change of Company Recommendation under this Agreement.

6.3                               AMEC confirms that the AMEC Board has by way of unanimous board resolution (a) determined that this Agreement, the Offer and the transactions contemplated hereby and thereby are in the best interests of AMEC and fair to the AMEC Shareholders, (b) approved this Agreement, and (c) resolved to recommend to the AMEC Shareholders the approval of the transactions contemplated by this Agreement.  Subject to clause 6.4, AMEC agrees that the AMEC Circular shall incorporate a recommendation from the AMEC Board to the AMEC Shareholders to vote in favour of the Acquisition and the AMEC Resolution to be proposed at the AMEC General Meeting (the “AMEC Recommendation”).

6.4                               AMEC further undertakes that it will not at any time make any Change of AMEC Recommendation, except to the extent that a majority of the AMEC Directors has determined in good faith (having taken appropriate financial and legal advice) that it is necessary to do so in order for the AMEC Directors to comply with their fiduciary duties and provided that AMEC shall notify the Company as soon as reasonably practicable of any Change of AMEC Recommendation.

7.                                      BOARD CHANGES AND APPOINTMENT RIGHTS

7.1                               AMEC shall procure that two (2) of the current non-executive directors of the Company shall be appointed as non-executive directors of AMEC upon the Offer Closing Date. The Company shall consult with AMEC regarding the identity, qualification and suitability of the persons to be so appointed, and such persons shall be identified pursuant to such consultation as soon as reasonably practicable after the date of this Agreement.

7.2                               AMEC shall procure that the persons appointed to the AMEC Board pursuant to clause 7.1 (the “Nominee Directors”) are proposed for re-election at the first AMEC annual general meeting following their appointment.

7.3                               The terms of appointment of each of the Nominee Directors shall be no less favourable than the terms of the existing non-executive directors of AMEC including as regards directors’ fees, directors and officers insurance and indemnities and AMEC agrees that it shall ensure that such insurance and indemnities also extend to any continuing role of the Nominee Directors as directors of the Company following Offer Closing as anticipated by clause 5.5(g).

7.4                               If the Nominee Directors are required to take responsibility for all or part of the AMEC Prospectus or any other Acquisition Document pursuant to applicable Laws, AMEC shall ensure that: (a) the Nominee Directors are given a reasonable opportunity to review and comment on drafts of such Acquisition Documents and to attend drafting and verification sessions in relation to such Acquisition Documents; (b) the Nominee Directors are given, to the extent reasonably requested by such Nominee Directors in order to obtain comfort in relation to the content of the relevant Acquisition Document, access to, and reasonable assistance from, AMEC management or relevant professional advisers; (c) the Nominee Directors receive the same reports, comfort letters and advice as is received by the other AMEC Directors in relation to the content and preparation of such Acquisition Document (including, but not limited to, accountant’s and other professional adviser’s reports and legal

18

advice) and where such items are addressed to the AMEC Directors such items shall also be addressed to the Nominee Directors as prospective Directors; and (d) the Nominee Directors are given the same rights (both as prospective directors and upon appointment as AMEC Directors) to indemnification, advancement of expenses and exculpation, and rights under directors’ and officers’ liability insurance as the AMEC Directors in relation to both matters arising from the date of this Agreement until the Nominee Directors are appointed as AMEC Directors and thereafter.

8.                                      RIGHTS UNDER SHARE PLANS

8.1                               The parties intend that, subject to the applicable rules of the Company Omnibus Plan, the applicable award agreements, employment agreements and any applicable Laws, the treatment of outstanding Company Awards will be as set out in this clause 8.1 and the parties will take all reasonable action to give effect to that intention:

(a)                                 in relation to outstanding Company Awards granted on or before 8 November 2012:

(i)                                all outstanding Options and RSUs will vest in full on the Offer Closing Date;

(ii)                all outstanding PRSUs will vest on the Offer Closing Date, to the extent that the Committee (as defined in the rules of the Company Omnibus Plan) determines that the applicable performance condition has been met as at the last practicable measurement date prior to the Offer Closing Date (with closing TSR calculated in a manner that is consistent with the applicable award agreements), and shall lapse as to the balance. For the avoidance of doubt, the Committee will not exercise any discretion to adjust the level of vesting having applied the numerical performance condition;

(iii)             the Company may elect to satisfy all vested Company Awards by delivery of Company Shares or by payment of a cash sum calculated by multiplying the number of Company Shares that have vested under the Company Award by the closing price of a Company Share on the last trading day prior to the Offer Closing Date less, in the case of Options only, any amount a participant would have been required to pay to exercise the Option.  Any such cash sum shall be paid no later than ten (10) Business Days after the Offer Closing Date and shall be subject to any applicable withholding Taxes.  For the avoidance of doubt, where the above calculation would result in a negative figure, then the cash payment is deemed to be nil; and

(iv)            to the extent that outstanding Company Awards are satisfied with Company Shares, the Company will take such steps as are reasonably necessary to enable participants to discharge their liability in respect of any applicable withholding Taxes (including arranging the sale of Company Shares on the participant’s behalf) and shall otherwise ensure those Company Shares are acquired from participants for the Offer Price pursuant to the Squeeze-Out Offer;

(b)                                 in relation to outstanding Company Awards granted after 8 November 2012:

(i)                                equivalent awards over AMEC Shares (the “Replacement Awards”) will be granted by AMEC in replacement for such Company Awards;

19

(ii)                the number of AMEC Shares subject to each Replacement Award will be calculated in accordance with the following formula:

A x 1.7996 = Z

where,

A is the number of Company Shares subject to the Company Award immediately prior to the Offer Closing Date, save that in the case of PRSUs only, A shall be 50% of the maximum award, and

Z is the number of AMEC Shares, rounded down to the nearest whole number, subject to the Replacement Award.

(iii)             in the case of an option, the total exercise price payable to exercise the Replacement Award will to the greatest extent possible be the same as the corresponding total exercise price for the Company Option which it replaces;

(iv)            Replacement Awards granted in respect of PRSUs will not be subject to any performance conditions; and

(v)               subject to clause 8.1(b)(iii) above, the terms of the Replacement Awards will be equivalent in all material respects to those of the Company Awards which they replace, but references to the Company shall be treated as references to AMEC. Subject to clause 8.1(b)(iv) above, the Replacement Award will vest, be exercisable and lapse at the same times as the Company Award it replaces. For the avoidance of doubt, in case of an option offered to a US participant, the terms of such Replacement Awards will comply with the requirements under US Treasury Regulation Section 1.409A-1(b)(5)(v)(D) or any successor provision thereto.

8.2                               The Company will procure that no adjustment will be made to Company Awards in respect of the cash dividend permitted pursuant to clause 14.1(g) and that no other modifications are made to Company Awards without the prior written consent of AMEC which would affect the entitlements of participants contemplated by this clause 8.

8.3                               Company Awards over approximately 636,475 Company Shares are due to vest in the ordinary course on 8 March 2014 with further awards over in aggregate approximately 129,141 Company Shares due to vest in May, August and September 2014. No other awards are expected to vest prior to the Offer Closing Date save in good leaver circumstances in accordance with the rules of the Company Omnibus Plan and any award agreements thereunder.

8.4                               The Company will make grants under the Company Omnibus Plan in March 2014. These and any other future grants will be in the ordinary course and grant criteria (size of individual grants, vesting schedule, participant population, performance conditions) will be consistent with normal practice (save that the terms of the Company Awards granted in 2014 will be such that Replacement Awards granted in respect of such Company Awards will vest on a pro-rata basis if the Offer Closing Date occurs in 2014 and a participant is involuntarily terminated in 2014), and subject to prior consultation with AMEC.  The overall cash value of grants under the Company Omnibus Plan (including to Section 16 Officers) in March 2014 (including the Company Award already granted to ▇▇ ▇▇▇▇▇ in 2014) will not exceed the total value of grants under the Company Omnibus Plan in 2013 (including to Section 16

20

Officers), in each case calculated at the relevant date of grant.  For the avoidance of doubt, Company Awards granted in March 2014 will be subject to the provisions of this clause 8.

8.5                               The Company will not, without prior consultation with AMEC or as otherwise contemplated by this clause 8, exercise any discretion whatsoever in relation to Company Awards granted under the Company Omnibus Plan.

9.                                      MANAGEMENT AND EMPLOYEES

9.1                               AMEC agrees that during the 12 month period from the Offer Closing Date it will not reduce any of the base salary, target and maximum opportunity under the Bonus Schemes, severance programs or any terms regarding future pension accrual/contributions of, or applicable to, any Company Group Employee, as in effect at such date (the “Key Employment Provisions”), or otherwise amend the terms of the Key Employment Provisions to the detriment of any Company Group Employee (other than by agreement with or as a consequence of an election by the individual concerned).

9.2                               In relation to all Welfare Benefit Plans which are in force as at the date of this Agreement, AMEC agrees that, subject to clause 9.3, either:

(a)                                 all such Welfare Benefit Plans will continue to apply to all relevant Company Group Employees on the same terms and conditions until the earlier of 12 months after the Offer Closing Date or the expiry of the relevant Welfare Benefit Plan; or

(b)                                 if any Welfare Benefit Plan is terminated prior to the earlier of 12 months after the Offer Closing Date or the expiry of the relevant Welfare Benefit Plan, AMEC shall replace it with a plan which provides broadly similar benefits to the relevant Company Group Employees and shall use its reasonable endeavours (subject to there being no material increase in the cost incurred by AMEC or any member of the AMEC Group compared to the Company Group) to ensure that:

(i)                  each relevant Company Group Employee is, to the extent relevant and subject to applicable Law and applicable Tax qualification, credited with his length of service with the Company Group for the purposes of eligibility to participate and vesting (except that no such service credit will be required if it results in a duplication of benefits);

(ii)               the relevant benefit provider or insurer waives all limitations as to pre-existing conditions, exclusions and waiting periods and actively-at-work requirements with respect to participation and coverage requirements applicable to Company Group Employees under such plan to the extent waived under the corresponding Company Welfare Benefit Plan; and

(iii)            each relevant Company Group Employee and his or her eligible dependants and beneficiaries is provided with credit under such replacement plan for any deductibles and similar expenses paid by such Company Group Employee under corresponding Company Benefit Plans in the calendar year in which such Company Group Employee (or his or her eligible dependants or beneficiaries) become eligible to participate in such replacement plan for the purpose of applying any applicable deductible, out-of-pocket or similar requirements as though such amounts had been paid in accordance with the terms and conditions of the applicable plan.

21

9.3                               The provisions of clauses 9.2(a) and 9.2(b) are subject to any changes, terms and/or conditions required or imposed by any relevant benefit plan provider or insurer or by law from time to time.

9.4                               The Company warrants and represents that the Bonus Schemes comprise formula-based corporate or business performance criteria and discretionary individual performance criteria.  AMEC agrees that it shall operate the Bonus Schemes for all eligible Company Group Employees for the calendar year in which the Offer Closing Date falls (the “Bonus Year”). Subject to clause 9.5, such bonuses shall be determined following the end of the Bonus Year at the normal time in accordance with the Company Group’s past practice in relation to the full Bonus Year based on the Company’s actual results at end of the Bonus Year.

9.5                               Without prejudice to any alternative treatment provided for in a Company Group Employee’s existing employment agreement, the parties agree that Company Group Employees whose employment is terminated involuntarily and without cause by AMEC (or by the Company at the request of AMEC), including, for the avoidance of doubt any Company Group Employee who is constructively dismissed (as determined by a court or tribunal of competent jurisdiction, after any appeal process is exhausted), on or before 31 December 2014 (each, a “Good Leaver”), shall be entitled to receive a bonus for the Bonus Year, pro-rated on a time basis up to the date on which their employment with the Company Group terminates (each, a “Good Leaver Bonus”). The parties agree that the performance criteria for such Good Leaver Bonuses shall be calculated by reference to results as at the last complete financial quarter prior to the Offer Closing Date. Good Leaver Bonuses shall be determined in accordance with and subject to any relevant Bonus Schemes by the Nominee Directors and shall be payable as soon as is reasonably practicable following the date on which the employment of the relevant Good Leaver is terminated by AMEC (or by the Company at AMEC’s request) or as soon as reasonably practicable following the date on which a court or tribunal of competent jurisdiction (after any appeals process is exhausted) determines that the relevant Good Leaver Employee has been constructively dismissed. In accordance with the Company Group’s existing practice all Good Leaver Bonuses shall be subject to the Company Group’s normal rules regarding clawback.

9.6                               Existing rights under the Company Omnibus Plan will be treated in accordance with clause 8 and, subject to clause 8, no further awards will be granted under the Company Omnibus Plan. Following the Offer Closing Date, Company Group Employees will be eligible to be considered for participation in the AMEC Employee Share Plans, subject to the rules and participation criteria of such plans from time to time.

9.7                               Prior to the Offer Closing, the Company (acting through its compensation committee or a committee of the Company Board that meets the requirements under Rule 14d-10(d)(2) under the Exchange Act) will take all such steps necessary to cause any negotiation, execution or amendment of an employment compensation, severance or other employee benefit arrangement (or payments made or to be made or benefits granted or to be granted according to such an arrangement) with respect to any Company Shareholder to be approved as an “employment compensation, severance or other employee benefit arrangement” within the meaning of Rule 14d-10(d)(1) under the Exchange Act and to otherwise satisfy the requirements of the non-exclusive safe harbour set forth in Rule 14d-10(d) under the Exchange Act.

9.8                               AMEC and the Company agree that, if a Company Group Employee who has unvested retirement contributions under a qualified defined contribution or defined benefit retirement plan maintained in the United States is terminated involuntarily and without cause, provided that it is permissible under and does not affect the applicable Tax qualification, such

22

steps shall be taken to the extent reasonably necessary and practicable to ensure that those retirement contributions vest and are not forfeited by the Company Group Employee.

10.                               DIRECTORS’ AND OFFICERS’ INDEMNIFICATION AND INSURANCE

10.1                        AMEC agrees that all rights to indemnification, advancement of expenses and exculpation by the Company Group now existing in favour of each person who is now, or has been at any time prior to the date hereof or who becomes prior to the Offer Closing Date an officer or director of the Company or any of its subsidiaries (each, a “D&O Indemnified Party”) as provided in the Company’s or any such subsidiary’s Charter Documents, in each case as in effect on the date of this Agreement, or pursuant to any other agreements in effect on the date hereof, shall remain in full force and effect in accordance with their terms and will not be amended, repealed or otherwise modified for the D&O Coverage Period (and, in the event that any relevant proceeding is pending or asserted or any relevant claim made during such period, until the final disposition of such proceeding or claim).

10.2                        From and after the Offer Closing, and for the D&O Coverage Period (and, in the event that any relevant proceeding is pending or asserted or any relevant claim made during such period, until the final disposition of such proceeding or claim), AMEC shall cause the Company or any of its successors or assigns to indemnify, defend and hold harmless each D&O Indemnified Party to the same extent such D&O Indemnified Party is indemnified as of the date of this Agreement (including with respect to advancement of expenses) by the Company pursuant to the Company’s or any subsidiary’s Charter Documents and indemnification agreements, if any, in existence on the date of this Agreement with such D&O Indemnified Party for acts or omissions occurring prior to the Offer Closing.

10.3                        The Company shall obtain as of the Offer Closing Date “tail” insurance policies with a claims period of the D&O Coverage Period (and, in the event that any relevant proceeding is pending or asserted or any relevant claim made during such period, until the final disposition of such proceeding or claim), and, with respect to coverage and amounts and other material terms and conditions, substantially equivalent, and no less favourable in the aggregate, to the directors and officers of the Company and its subsidiaries, in each case with respect to claims arising out of or relating to events which occurred on or prior to the Offer Closing Date (including in connection with the transactions contemplated by this Agreement), than the Company’s current policies of directors’ and officers’ liability insurance maintained by the Company Group as of the date hereof (the “Current D&O Cover”); provided, however, that in no event will the Company Group be required to expend a premium for such coverage in excess of two hundred and fifty per cent. (250%) of the last annual premium paid by the Company Group for such insurance prior to the date of this Agreement (the “Maximum Premium”); provided, further, that if such insurance coverage cannot be obtained at a premium equal to or less than the Maximum Premium, the Company Group will obtain that amount of directors’ and officers’ insurance (or “tail” coverage) obtainable for a premium equal to the Maximum Premium.  If requested to do so by the Company, AMEC agrees that it will pay, directly, the premium in respect of the policies referred to in this clause, up to but not exceeding the Maximum Premium.

10.4                        The agreements and covenants contained herein shall not be deemed to be exclusive of any other rights to which any D&O Indemnified Party is entitled, whether pursuant to Law, contract or otherwise.  Nothing in this Agreement is intended to, shall be construed to or shall release, waive or impair any rights to directors’ and officers’ insurance claims under any policy that is or has been in existence with respect to the Company or its subsidiaries or any of their respective officers, directors and employees, it being understood and agreed that the indemnification provided for in this clause 10 is not prior to, or in substitution for, any such claims under any such policies.

23

10.5                        In the event the Company or any of its successors or assigns (a) consolidates with or merges into any other person and shall not be the continuing or surviving corporation or entity in such consolidation or merger or (b) transfers all or substantially all of its properties and assets to any person, then, and in either case, proper provision shall be made so that the successors and assigns of the Company (in particular as a result of the Squeeze-Out Merger) shall assume all of the obligations of the Company and its subsidiaries set forth in this clause 10. Without limiting the foregoing, throughout the D&O Coverage Period AMEC shall ensure that the Company (or its successors or assigns) have sufficient funds to enable it to pay the $1 million deductible in the manner such deductible currently exists and applies in respect of the Side B and Side C Current D&O Cover.

11.                               NON-SOLICITATION

11.1                        Except as expressly permitted by this clause 11, from the date hereof and continuing until the Offer Closing Date or, if earlier, the termination of this Agreement in accordance with clause 15, the Company undertakes that:

(a)                                 it shall, and shall cause its subsidiaries to, and shall direct its and their respective directors, officers, employees, agents, Company Financial Advisers, counsel and other advisers (collectively, the “Company Representatives”) to, immediately cease and cause to be terminated all existing solicitations, discussions, negotiations and communications with any persons with respect to any Competing Proposal and shall request that each such person and any other persons who have made or have indicated an intention to make a Competing Proposal promptly return or destroy any confidential information previously furnished by the Company; and

(b)                                 it shall not, and it shall cause its subsidiaries and the Company Representatives not to, directly or indirectly:

(i)                  grant any waiver or release under, or terminate, any “standstill” or similar obligation with respect to the Company or any of its subsidiaries;

(ii)               encourage, solicit, initiate or facilitate any discussions or negotiations with any person or persons (other than AMEC or any affiliate or associate of AMEC) concerning any Competing Proposal or otherwise seeking to procure any Competing Proposal;

(iii)            furnish to any person other than AMEC any non-public information regarding the Company or any of its subsidiaries, afford to any person (other than AMEC or designees of AMEC) access to the business or to the properties, assets, books, records or non-public information, or to any personnel, of the Company or any of its subsidiaries, in any such case that would reasonably be expected to result in the making, submission or announcement of, or for the purpose of encouraging, soliciting, initiating, facilitating or otherwise procuring, a Competing Proposal or any inquiries that would reasonably be expected to lead to a Competing Proposal;

(iv)           approve, endorse, recommend, execute or enter into any agreement, letter of intent or contract with respect to a Competing Proposal or otherwise relating to or that is intended to or would reasonably be expected to lead to any Competing Proposal or enter into any agreement, arrangement, or understanding requiring it to abandon, modify, amend, terminate or fail to consummate the Offer or any other transactions contemplated by this Agreement;

24

(v)              submit any Competing Proposal or any matter related thereto to the vote of the Company Shareholders unless and until there has been a Change of Company Recommendation in accordance with clause 6.2;

(vi)           participate in any discussions or negotiations with any third party with respect to any Competing Proposal;

(vii)        adopt, authorise or approve a Competing Proposal or publicly propose to recommend any Competing Proposal; or

(viii)     subject to clause 6.2, authorise, propose, commit, resolve or agree to do any of the foregoing;

provided, however, that nothing contained in this clause 11 shall prohibit the Company or any of the Company Representatives or the Company Board from (A) taking and disclosing to the Company Shareholders, or any third parties or Governmental Authorities, a position with respect to a Competing Proposal initiated by a third party (including a position contemplated by Rule 14d-9, Rule 14e-2(a) or Item 1012(a) of Regulation M-A promulgated under the Exchange Act) or (B) from making such other disclosure to the Company Shareholders, or any third parties or Governmental Authorities to the extent in the case of either (A) or (B), if the Company Board determines in good faith, after consultation with outside legal counsel, that the failure to make such disclosure would reasonably be expected to be inconsistent with the Company Directors’ fiduciary duties under applicable Laws; provided, however, that no such disclosure shall (a) have the substantive effect of withholding, withdrawing or amending or modifying the Company Recommendation in a manner adverse to AMEC or (b) fail to reaffirm the Company Recommendation, if such disclosure is to Company Shareholders or in a public announcement and in each case in circumstances in which the reaffirmation of the Company Recommendation would be reasonably expected, in each case, unless in accordance with clause 6.2.

11.2                        Notwithstanding anything to the contrary contained in this clause 11, if at any time following the date hereof and prior to the Offer Closing: (a) the Company has received a bona fide written Competing Proposal from a third party that did not result from the Company’s material breach of this clause 11, which Competing Proposal was made on or after the date hereof, and such Competing Proposal has not been withdrawn, and (b) the Company Board determines in good faith (after consultation with its outside counsel and outside financial advisers) that (i) failure to take any of the actions described in clauses (A) through (E) below would likely constitute or would reasonably be expected to result in a breach of its fiduciary duties under applicable Laws or (ii) such Competing Proposal constitutes or is reasonably likely to lead to a Superior Proposal, then the Company may (A) furnish information with respect to the Company and its subsidiaries, and afford access to the business or to the properties, assets, books, records or non-public information, or to any personnel, of the Company and its subsidiaries, to the person making such Competing Proposal and its representatives; (B) initiate or participate in discussions or negotiations with the person making such Competing Proposal and its representatives regarding such Competing Proposal; (C) grant any waiver or release under, or terminate, any “standstill” or similar obligation with respect to the Company or any of its subsidiaries to the extent required in connection with making (but not consummating) such Competing Proposal; (D) take any other action in connection with such Competing Proposal that any court of competent jurisdiction orders the Company to take; and (E) propose, resolve or agree to do any of the foregoing; provided, however, that the Company will not, will not permit its subsidiaries to, and will not authorise the Company Representatives to, disclose any non-public information regarding the Company to such person without first entering into an Acceptable Confidentiality Agreement with such person.  The Company will (1) promptly (and in any event within one (1) Business Day

25

following receipt) provide written notice to AMEC of the receipt of any Competing Proposal, which notification shall include (i) the applicable written Competing Proposal (or, if oral, the material terms and conditions of such Competing Proposal) and (ii) the identity of the person making such Competing Proposal and (2) promptly provide to AMEC any material information concerning the Company or its subsidiaries provided or made available to such other person (or its representatives) that was not previously provided or made available to AMEC.

11.3                        AMEC and the Company acknowledge and hereby agree that any violation of the restrictions set forth in this clause 11 by any of the Company Representatives (in the case of any such Company Representative who is an investment banker, financial adviser, attorney, accountant or other adviser, to the extent that such Company Representative is or has been engaged by the Company in connection with the transactions contemplated hereby whether or not the engagement has terminated) shall be deemed to be a breach of this clause 11 by the Company.

11.4                        Notwithstanding anything herein to the contrary, at any time prior to the Expiration Time, the Company Board may (in addition to the rights of the Company to take the actions referred to in clause 11.2 in the circumstances contemplated therein), take any of the actions listed in clause 11.1(b) if: (a) the Company notifies AMEC, in writing, at least three (3) Business Days (the “Notice Period”) before taking any such action, of its intention to take such action with respect to a Superior Proposal, which notice shall state the Company has received a Competing Proposal (that did not result from a material breach of this clause 11) which the Company Board intends to declare a Superior Proposal; (b) the Company offers AMEC the opportunity to negotiate during the Notice Period in good faith to make such adjustments to the terms and conditions of this Agreement so that such Competing Proposal ceases to be a Superior Proposal (it being understood and agreed that in the event of an amendment altering any material term or terms of such Superior Proposal: (i) upon each of the first and second such amendments, the Company shall notify AMEC in writing and AMEC shall have an additional one (1) Business Day period from the date of such notice to so negotiate; and (ii) in the event of any further amendments thereafter, the Company shall not be obliged to notify AMEC and AMEC shall not have any additional period to so negotiate); and (c) the Company Board determines in good faith (after consultation with outside counsel and outside financial advisers) that such Competing Proposal, taking into account any changes to the terms and conditions of this Agreement proposed by AMEC during the Notice Period (and by the relevant third party in respect of its Competing Proposal), constitutes a Superior Proposal.

12.                               CONFIDENTIALITY

Each party shall keep all information relating to the other party, any member of the other party’s Group or any part of the other party’s business or assets obtained by them pursuant to this Agreement confidential in accordance with the provisions of the confidentiality agreement, dated 26 August 2013 (the “Confidentiality Agreement”), between AMEC and the Company.

13.                               CERTAIN FUNDS

13.1                        AMEC warrants and represents to the Company that:

(a)                                 subject to satisfaction or waiver of the Conditions, it will be in a position to satisfy full implementation of the Acquisition and pay the amount equal to the Due Amounts as and when required;

26

(b)                                 it has available loan facilities under the Financing Document which will at Offer Closing provide in immediately available funds the necessary cash resources to pay the Due Amounts due at that time;

(c)                                  it has made available to the Company a complete and accurate copy of the Financing Document and the CP confirmation letter from Bank of America ▇▇▇▇▇▇▇ ▇▇▇▇▇ International Limited to AMEC plc dated 13 February 2014 (the “CP Confirmation Letter”);

(d)                                 the status of the conditions precedent to be satisfied by AMEC plc pursuant to, and with respect to the initial utilisation under, the Financing Document is as set out in the CP Confirmation Letter, and there are no other conditions precedent to initial utilisation except as set out in such CP Confirmation Letter and Part 1 of Schedule 2 of the Financing Document;

(e)                                  it believes that it will be able to satisfy on a timely basis any outstanding condition precedent to be satisfied by it pursuant to, and with respect to the initial utilisation under, the Financing Document; and

(f)                                   there are no material terms, pre-conditions or conditions relating to the debt financing (other than fee and syndication arrangements) included in any contract, agreement or other binding instrument or arrangement other than those terms or conditions contained in the Financing Document.

13.2                        AMEC undertakes to the Company that:

(a)                                 it will or will procure that all actions required to be taken by it under this Agreement and the Financing Document as and when required pursuant to the terms thereof are taken, including the exercise in full of the rights under the Financing Document so as to enable it to receive in sufficient time such amounts as are necessary to enable it to satisfy the Due Amounts;

(b)                                 it will take all such reasonable steps as are within its power as may be necessary to ensure that there will be no breach of any representation, warranty or covenant given, or to be given, by it or any member of its Group in the Financing Document which would entitle the relevant debt provider or providers, to refuse to provide funds under the Financing Document and, in particular, it will take all such reasonable steps as are within its power to procure that no event of default or Drawstop Event occurs which would permit the relevant lenders to decline to make advances or payments under the Financing Document as necessary to enable satisfaction of the Due Amounts; and

(c)                                  until the Offer Closing, it will not exercise any right to amend, terminate, cancel or rescind the Financing Document (or any provision thereof) in a manner prejudicial to AMEC’s ability to satisfy the Due Amounts without the Company’s prior written consent.

13.3                        For the avoidance of doubt, it is understood and agreed that AMEC’s obligation to consummate the Acquisition and to purchase and pay for the Company Shares pursuant to this Agreement and the Offer Documents is not conditioned on AMEC obtaining any debt, equity or other financing.

14.                               CONDUCT OF BUSINESS

14.1                        From the date of this Agreement until the Offer Closing Date, the Company covenants and agrees as to itself and its subsidiaries (unless AMEC shall otherwise approve in

14.3                        Prior to making any written or oral communications to the directors, officers, employees or independent contractors of the Company or any of its subsidiaries pertaining to compensation or benefit matters that are affected by the transactions contemplated by this Agreement, the Company shall, subject to applicable Laws, reasonably consult with AMEC in relation thereto.

(a)                                 as agreed in writing by the Company and AMEC at any time prior to the Expiration Time;

(ii)               the Company shall have, within ten (10) Business Days after the public announcement of a Competing Proposal, failed to reaffirm (publicly, if requested by AMEC) the Company Recommendation (it being agreed and understood that communications of the kind described in the final sentence of clause 6.2 shall not trigger the termination right contemplated by this clause (ii));

32

(iii)            at a duly convened and held Company General Meeting (or any adjournment or postponement thereof), the Company Resolutions are voted upon but not passed by the Company Shareholders;

(iv)           the Company Board shall have effected a Change of Company Recommendation or the Company shall have, within ten (10) Business Days after the public announcement of a Competing Proposal, failed to reaffirm (publicly, if requested by AMEC) the Company Recommendation (it being agreed and understood that communications of the kind described in the final sentence of clause 6.2 shall not trigger the termination right contemplated by this clause 15.1(c)(iv));

(v)              AMEC fails to consummate the Offer in accordance with clause 1.10 upon satisfaction or waiver of the Conditions;

(vi)           any Competing Proposal becomes or is declared wholly unconditional or is completed; or

(vii)        an AMEC Material Adverse Effect has occurred;

(d)                                 upon service of a written termination by either party on the other if prior to the Expiration Time:

(i)                  (A) either AMEC or the Company (the relevant party, the “Breaching Party”) has breached or failed to perform any of its covenants or agreements contained in this Agreement, in any case, such that such breach or failure to perform would cause a Condition not to be satisfied; (B) the non-breaching party shall have delivered to the Breaching Party written notice of such breach or failure to perform; and (C) either such breach or failure to perform is not capable of cure (which cure would permit the satisfaction of such Condition) or at least thirty (30) days shall have elapsed since the date of delivery of such written notice to the Breaching Party and such breach or failure to perform shall not have been cured; provided, however, that the non-breaching party shall not be permitted to terminate this Agreement pursuant to this clause 15.1(d)(i) if the non-breaching party is then in breach or has failed to perform any of its covenants or agreements contained in this Agreement, in any case, such that a Condition would not be satisfied;

(ii)               any Condition which is incapable of waiver is incapable of satisfaction;

(iii)            any Condition which has not been waived, is incapable of satisfaction and that, notwithstanding that AMEC has the right to waive such Condition, it notifies the Company in writing that it will not do so;

(iv)           the Conditions have not been satisfied (or, to the extent permitted, waived) by the Longstop Date; or

(v)              if any court of competent jurisdiction or other applicable Governmental Authority has issued a final order, decree or ruling or taken any other final action restraining, enjoining or otherwise prohibiting the Offer and such order, decree, ruling or other action has become final and non-appealable; provided, however, that the terms of this clause 15.1(d)(v) will not be available to any party (x) where such party’s actions or omissions (whether in breach of this Agreement or otherwise) caused any such order, decree, ruling or action or (y) unless such party will have used all reasonable endeavours to

33

oppose any such order, decree, ruling or other action or to have the same vacated or made inapplicable to the Offer;

provided, however, that the rights of termination under clauses 15.1(d)(i) to 15.1(d)(iv) (inclusive) shall not be available to a party whose material breach of this Agreement has been the cause of, or otherwise resulted in, such Condition having become incapable of satisfaction, or, not having been satisfied, by the Longstop Date.

15.2                        If this Agreement is terminated pursuant to clause 15.1 above, this Agreement, except for the provisions of this clause 15 and clauses 12, 16, 17, 18, 19, 20 (including, for the avoidance of doubt, such clauses referenced in clause 20.6 as surviving termination of this Agreement) and 21 and Schedule 1, shall forthwith become void and have no effect, without any liability on the part of any party or its directors, officers or shareholders; provided, however, that the termination of this Agreement shall be without prejudice to, and shall not affect, any rights, remedies, obligations or liabilities of the parties that have accrued up to the date of termination, including the rights provided for under clause 20.3.

15.3                        Save as expressly provided in this Agreement, neither party shall be entitled to rescind or terminate this Agreement in any circumstances whatsoever (whether before or after the Offer Closing Date).  This shall not exclude any liability for (or remedy in respect of) fraud or fraudulent misrepresentation.

16.                               COST REIMBURSEMENT

16.1                        The parties agree that the Cost Reimbursement will become payable in the circumstances set out in clauses 16.2 and 16.3. The applicable fixed compensation sum shall represent a lump sum payment for the purpose of compensating the relevant party for certain internal expenditures and external costs incurred in connection with the preparation for and in consideration of the realisation of the Acquisition, and is not intended in any way whatsoever to coerce a party into completing the Acquisition.

16.2                        The Company undertakes that it will, upon written demand by AMEC, pay to AMEC the Cost Reimbursement in the event:

(a)                                 that this Agreement is terminated pursuant to clauses 15.1(b)(i), 15.1(b)(ii) or 15.1(c)(iv) provided that an AMEC Material Adverse Effect has not occurred prior to such termination;

(b)                                 that this Agreement is terminated pursuant to clauses 15.1(b)(v), or 15.1(c)(vi); or

(c)                                  (i) a Competing Proposal is announced after the date hereof, (ii) thereafter, this Agreement is terminated by either AMEC or the Company pursuant to clause 15 (other than termination (A) by the Company pursuant to clauses 15.1(c)(i), 15.1(c)(ii), 15.1(c)(v) or 15.1(c)(vii) (B) by the Company pursuant to clause 15.1(d)(i) or (C) either party pursuant to 15.1(d)(ii), 15.1(d)(iii) or 15.1(d)(iv) in respect of Conditions 1, 2, 9, 10 or 11); and (iii) within nine (9) months of such termination, the Company or any of its subsidiaries executes an alternative acquisition agreement with respect to, or consummates, approves or recommends to the Company Shareholders to accept, any such Competing Proposal made after the date of this Agreement and prior to the date of the termination of this Agreement.

16.3                        AMEC undertakes that it will, upon written demand by the Company, pay to the Company the Cost Reimbursement in the event that this Agreement is terminated:

34

(a)                                 pursuant to clauses 15.1(c)(i) or 15.1(c)(v), provided that a Company Material Adverse Effect has not occurred prior to such termination; or

(b)                                 pursuant to clauses 15.1(d)(ii), 15.1(d)(iii) or clause 15.1(d)(iv), in each case, in circumstances where Condition 2 has not been satisfied (or waived), provided that a Company Material Adverse Effect has not occurred prior to such termination.

16.4                        The applicable party shall pay the Cost Reimbursement by no later than three (3) Business Days after the date of the written demand that causes it to become payable pursuant to clause 16.2 or 16.3 (as applicable).

16.5                        All sums payable under this clause 16 shall be paid in the form of an electronic funds transfer for same day value to such bank account as may be notified by the party entitled to receive such sums in writing to the party responsible for payment and shall be paid in full free from any deduction or withholding whatsoever (save only as may be required by applicable Laws) and without regard to any lien, right of set-off, counterclaim or otherwise.

16.6                        The parties anticipate, and shall use all reasonable endeavours to procure, that the Cost Reimbursement is not and will not be treated as consideration for a taxable supply for VAT purposes. If, however, the Cost Reimbursement is determined by any Tax authority to be consideration in whole or part for a taxable supply for VAT purposes, and VAT is chargeable thereon, then:

(a)                                 if the Cost Reimbursement is determined by a relevant Tax authority to be consideration for a taxable supply in respect of which the recipient of the Cost Reimbursement (the “Payee”) or the representative member of any VAT group of which the Payee is a member for VAT purposes is liable to account for VAT, then:

(i)                  if and to the extent that such VAT is not recoverable by the payer of the Cost Reimbursement (the “Payer”) or the representative member of any VAT group of which the Payer is a member for VAT purposes (the “Payer Representative Member”) by repayment, credit, deduction or refund, the Payer and Payer Representative Member having used all reasonable endeavours to recover such VAT no additional amount shall be paid in respect of VAT and the Cost Reimbursement shall be VAT inclusive to that extent; and/or

(ii)               if and to the extent that such VAT is recoverable by the Payer or the Payer Representative Member by repayment, credit, deduction or refund (whether under domestic rules, Council Directives 2008/9/EC or 86/560/EEC or otherwise), the amount of the Cost Reimbursement shall be increased to the extent necessary to take account of such recoverable VAT; and

(b)                                 if under a reverse charge mechanism the Cost Reimbursement is determined by a relevant Tax authority to be consideration for a taxable supply in respect of which the Payer or the Payer Representative Member is liable to account for VAT then, to the extent that any VAT chargeable on the supply is not recoverable by the Payer or the Payer Representative Member by repayment, credit, deduction or refund, the Payer and Payer Representative Member having used all reasonable endeavours to recover such VAT, the amount of the Cost Reimbursement shall be reduced to the extent necessary to take account of any such irrecoverable VAT;

such that after making any such adjustments the aggregate of (i) the total amount of the Cost Reimbursement paid to the Payee (including any amount in respect of VAT), plus (ii) any irrecoverable VAT incurred under a reverse charge mechanism (together with any related

35

interest or penalties in respect of such reverse charge VAT but excluding any interest or penalties arising as a result of the unreasonable delay or default of the Payer or relating to any period after the Payee has accounted to the Payer for any reduction in the Cost Reimbursement pursuant to this clause), less (iii) any repayment, credit, deduction or refund obtained as referred to in clause 16.6(a)(ii), shall be equal to the amount that the Cost Reimbursement would have been in the absence of any such VAT.

16.7                        Such adjusting payment or payments as may be required between the parties to give effect to clause 16.6 above shall be made five (5) Business Days after the date on which the determination by the relevant Tax authority which results in such payment being required has been communicated to the party required to make the payment (together with such evidence of it as is reasonable in the circumstances to provide and, where clause 16.6(a) applies, together with the provision of a valid VAT invoice) or, if later, (in the case of clause 16.6(a)(ii)) five (5) Business Days after the VAT is recovered or (in the case of clause 16.6(b)) five (5) Business Days before the VAT is required to be accounted for.

16.8                        Notwithstanding anything in this Agreement to the contrary, in the event that a party (the “Notifying Party”) notifies the other party (the “Receiving Party”) that it wishes to receive the Cost Reimbursement pursuant to and in accordance with clause 16.2 or 16.3 (as applicable) and the Receiving Party duly discharges said amount pursuant to clauses 16.4 and 16.5, the Cost Reimbursement shall constitute the sole and exclusive remedy of the Notifying Party, with respect to any and all claims against the Receiving Party, as the case may be, of whatever nature and whenever arising, relating to or arising out of this Agreement, the Offer or the Acquisition. Nothing in this clause 16.8 shall limit or exclude any liability for fraud or fraudulent misrepresentation. In no event shall a party be required to pay the Cost Reimbursement on more than one occasion.

17.                               FEES AND EXPENSES

Subject to clauses 1.11, 5.3, 5.8 and 16 and without prejudice to its other rights pursuant to this Agreement (or in relation to a breach by either party of the terms of this Agreement), each party shall pay its own costs and expenses in connection with or incidental to the Acquisition.

18.                               PUBLIC DISCLOSURE

Without prejudice to the other provisions of this Agreement, AMEC (and its affiliates) and the Company (and its affiliates) will consult with each other and agree on the desirability, timing and substance of any press release, public announcement, publicity statement or other disclosure relating to the Acquisition and, subject to applicable Laws, stock exchange rules and the requirements of any Governmental Authority, neither AMEC (or its affiliates) nor the Company (or its affiliates) will make any public disclosures without the prior consent of the other party (which consent shall not be unreasonably withheld or delayed) as to the timing of such disclosure, extent of distribution and form and substance thereof.

19.                               NOTICES

All notices, requests, claims, demands and other communications hereunder shall be in writing in English and shall be delivered by hand, fax, email, registered post or courier using an internationally recognised courier company. A notice, request, claim, demand or other communication shall be effective upon receipt and shall be deemed to have been received (a) at the time of delivery, if delivered by hand, registered post or courier or (b) at the time of transmission if delivered by fax or email provided that, in either case, where delivery occurs outside Working Hours, notice shall be deemed to have been received at the start of Working Hours on the next following Business Day.

20.                               MISCELLANEOUS

20.1                        This Agreement constitutes the entire agreement between the parties relating to the Acquisition and supersedes any previous agreement whether written or oral between the parties in relation to the Acquisition, except that (a) the confidentiality provisions in the Confidentiality Agreement shall remain in full force and effect in accordance with the terms of such agreement, (b) clause 7.2 of the Confidentiality Agreement (as it relates to customers, suppliers, contractors and sub-contractors) shall remain in full force and effect until the Offer Closing Date and (c) clauses 9 and 10 of the Confidentiality Agreement shall remain in full force and effect until the commencement of the Offer by AMEC as contemplated by clause 1.6. The parties agree that the non-solicitation agreement entered into between the parties on 12 January 2014 shall terminate and have no further effect upon the signing of this Agreement.

20.2                        Each of the Company and AMEC acknowledge that in entering into this Agreement it is not relying upon any pre-contractual statement that is not set out in this Agreement. AMEC agrees and undertakes to the Company (the Company contracting for itself and on behalf of each other Company Relevant Persons) that neither it nor any other member of the AMEC Group shall have any right of action against, and will waive and shall not make any claim against, the Company and/or any other Company Relevant Person arising out of or in connection with any pre-contractual statement except for a claim against the Company to the extent that such pre-contractual statement is repeated in this Agreement. Except for any liability in respect of a breach by a party of this Agreement, no Company Relevant Person shall owe any duty of care or have any liability in tort or otherwise to any member of the AMEC Group or any of their respective employees, directors, officers, agents or advisers. Without prejudice to the Company’s obligations under clauses 3.2 and 3.4, no Company Relevant Person shall have any personal liability to any member of the AMEC Group in relation to any statements made or information provided pursuant to clauses 3.2 and 3.4. The Company agrees and undertakes to AMEC (AMEC contracting for itself and on behalf of each other AMEC Relevant Person) that neither it nor any other member of the Company Group shall have any right of action against, and will waive and shall not make any claim against, AMEC and/or any other AMEC Relevant Persons arising out of or in connection with any pre-contractual statement except for a claim against AMEC to the extent that such pre-contractual statement is repeated in this Agreement. Except for any liability in respect of a breach by a party of this Agreement, no AMEC Relevant Person shall owe any duty of care or have any liability in tort or otherwise to any member of the Company Group or any of their respective employees, directors, officers, agents or advisers.  In accordance with clause 20.6, the provisions of this clause 20.2 may be relied upon and enforced by each Company Relevant Person.  For the purposes of this clause, “pre-contractual statement” means any draft, agreement, undertaking, representation, warranty, promise, assurance or arrangement of any nature whatsoever, or information or data provided, whether or not in writing, relating to the subject matter of this Agreement made or given by any person at any time prior to the date of this Agreement.  Nothing in this clause 20.2 shall exclude any liability for (or remedy in respect of) fraud or fraudulent misrepresentation.

20.3                        Subject to clause 16.8 and without prejudice to any other rights and remedies which either party may have; (a) each party acknowledges and agrees that damages would not be an adequate remedy for any breach by either party of the provisions of this Agreement (including

38

in particular clause 13) and either party shall be entitled to seek the remedies of injunction, specific performance and other equitable relief (and neither party shall contest the appropriateness or availability thereof), for any threatened or actual breach of any such provision of this Agreement by any party and no proof of special damages will be necessary for the enforcement by any party of the rights under this Agreement; and (b) the remedies available to either party pursuant to this clause 20.3 shall be cumulative and in addition to any other remedy to which that party is otherwise entitled under this Agreement, at law or in equity, and the election by either party to pursue an injunction, specific performance or other equitable relief (including damages in the event the other party opposes the granting of an injunction, specific performance or other equitable relief) shall not restrict, impair or otherwise limit that party from terminating this Agreement, nor shall such election restrict, impair or otherwise limit that party from seeking damages.

20.4                        No failure or delay by a party in exercising any right or remedy provided by Law or under this Agreement or any Acquisition Document shall impair such right or remedy or operate or be construed as a waiver or variation of it or preclude its exercise at any subsequent time and no single or partial exercise of any such right or remedy shall preclude any further exercise of it or the exercise of any other remedy.

20.5                        Neither of the parties to this Agreement may (or purport to) assign, transfer, charge or otherwise deal with all or any of its rights under this Agreement nor grant, declare, create or dispose of any right or interest in it without the prior written consent of the other party.

2.4                               AMEC Reports; Financial Statements

(a)                                 AMEC has filed or furnished, as applicable, on a timely basis all circulars, notices, prospectuses, resolutions, reports and other documents (including notifications to a RIS (as defined in the Listing Rules)) required to be filed or furnished by it under the Listing Rules and/or the prospectus rules made by the UK Listing Authority under Part VI of the Financial Services and Markets ▇▇▇ ▇▇▇▇ and/or the disclosure and transparency rules made by the UK Listing Authority under Part VI of the Financial Services and Markets ▇▇▇ ▇▇▇▇ since the Applicable Date (collectively, the “AMEC Reports”). Each of the AMEC Reports, at the time of its filing or being furnished, or if amended prior to the date hereof, as of the date of such amendment, complied as to form in all material respects with the applicable requirements of the UK Listing Authority and other applicable Laws. As of their respective dates, the AMEC Reports did not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements made therein, in light of the circumstances in which they were made, not misleading, except to the extent that the information in such AMEC Report has been amended or superseded by a later AMEC Report filed prior to the date hereof.

(b)                                 AMEC is in compliance in all material respects with the applicable listing and corporate governance rules and regulations of the LSE.

(c)                                  AMEC maintains a system of internal controls, including, but not limited to, disclosure controls and procedures, internal controls over accounting matters and financial reporting, an internal audit function, and legal and regulatory compliance controls (collectively, “Internal Controls”), that comply in all material respects with applicable Laws and are sufficient to provide reasonable assurances that (i) transactions are executed in accordance with management’s general or specific authorisations, (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with IFRS and to maintain accountability for assets, (iii) access to assets is permitted only in accordance with management’s general or specific authorisation, (iv) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences and (v) AMEC understands the nature of the responsibilities and obligations of its directors under the Listing Rules and the disclosure and transparency rules made by the UK Listing Authority under Part VI of the Financial Services and Markets ▇▇▇ ▇▇▇▇. The Internal Controls are overseen by the audit committee of the AMEC Board (the “AMEC Audit Committee”). In the last three years, AMEC has not publicly disclosed or reported to the AMEC Audit Committee or the AMEC Board, a significant deficiency, material weakness or material change in Internal Controls or fraud involving management or other employees who have a significant role in Internal Controls, any violation of, or failure to comply with, applicable Laws, or any matter which, in each such case, if determined adversely, either individually or in the aggregate, would have an AMEC Material Adverse Effect.

2.6                               Compliance with Laws

The businesses of each of AMEC and its subsidiaries have not been since the Applicable Date, and are not being, conducted in violation of any Laws, except for violations that, individually or in the aggregate, are not reasonably likely to have an AMEC Material Adverse Effect. Except with respect to the Antitrust Clearances and Clearances, no investigation or review by any Governmental Authority with respect to AMEC or any of its subsidiaries is pending or, to the knowledge of AMEC, threatened in writing, except for those the outcomes of which are not, individually or in the aggregate, reasonably likely to have an AMEC Material Adverse Effect.

2.7                               Anti-Corruption Laws

(a)                                 Since December 31, 2008, to the knowledge of AMEC, neither AMEC nor any of its subsidiaries nor any of its directors, officers or employees, nor any other person acting (or who has acted) on the behalf of AMEC or its subsidiaries, has engaged in any activity or conduct that has resulted or will result in a material violation of:
