    FOR IMMEDIATE RELEASE

    23 May 2017

      Recommended all-share offer by John Wood Group PLC ("Wood Group") for Amec   
                      Foster Wheeler plc ("Amec Foster Wheeler")                   
             Publication of Prospectus and Circular (this "Announcement")          

    On 13 March 2017 the Boards of Wood Group and Amec Foster Wheeler jointly
    announced that they had reached agreement on the terms of a unanimously
    recommended all-share offer for Amec Foster Wheeler (the "Combination") (the "
    Original Announcement"). The Wood Group Board believes that the Combination
    will accelerate delivery of Wood Group's strategic objectives to improve its
    service offering in project delivery, to enhance capability across the value
    chain in core oil and gas markets, and to broaden and deepen end market and
    customer exposure.

    Unless otherwise defined in this Announcement, terms defined in Wood Group's
    Original Announcement of the Combination on 13 March 2017 have the same meaning
    where used in this Announcement.

    Under the terms of the Combination, Amec Foster Wheeler Shareholders will
    receive 0.75 new Wood Group Shares for each Amec Foster Wheeler Share. Based on
    the Closing Price of £7.52 per Wood Group Share on 10 March 2017, this
    represents a value of approximately £5.64 per Amec Foster Wheeler Share and a
    premium of 15.3 per cent. to the Closing Price of £4.89 on 10 March 2017 (being
    the last Business Day before the date of the Original Announcement).

    Today, Wood Group published a Circular and a Prospectus ahead of the Wood Group
    General Meeting, scheduled for 11.00 a.m. on 15 June 2017. Approval will be
    sought from Wood Group Shareholders for the Combination to be effected by a
    scheme of arrangement of Amec Foster Wheeler.  

    The Circular and the Prospectus have each been approved by the UK Listing
    Authority and are now available at www.woodgroup.com. A copy of each of the
    Circular and the Prospectus has been submitted to the National Storage
    Mechanism and will shortly be available for viewing at www.morningstar.co.uk/uk
    /nsm. Amec Foster Wheeler has separately published a Scheme Document ahead of
    its own General Meeting on 15 June 2017.

    The Combination is intended to result in:

      * the creation of a global leader in project, engineering and technical
        services delivery across a broad range of industrial markets, predominantly
        focussed on oil & gas which represents c. 55 per cent. of pro-forma
        revenues across upstream, midstream and downstream;  

      * accelerated delivery of Wood Group's strategic objectives to improve its
        asset life cycle service offering in project delivery, to enhance
        capability across the value chain in core oil and gas markets, and to
        broaden and deepen end market and customer exposure and reduce earnings
        volatility through oil and gas cycles;
       
      * Wood Group's measured risk appetite continuing in a flexible asset light
        model with revenues derived principally from reimbursable work; and
       
      * superior returns from the delivery of significant cost and revenue
        synergies. The level of annual pre-tax cost synergies arising from the
        transaction by the end of the third year following completion of the
        Combination ("Completion") was increased to £150m per annum from £110m per
        annum on 5 April 2017 and has been further increased to at least £165m per
        annum, again by the end of the third year following the completion of the
        Combination, in the Circular and the Prospectus released today.
       
        The Combined Group will be led by Robin Watson as Chief Executive and David
        Kemp as CFO. Ian Marchant will continue as Chair. As disclosed in the
        circular and the prospectus, on completion, certain members of the Amec
        Foster Wheeler Board will join the Board of the Combined Group. Roy
        Franklin will join as Deputy Chair and Senior Independent Director, and Ian
        McHoul and Linda Adamany will be appointed as non-executive directors.

    Update to the Wood Group Quantified Financial Benefits Statement

    The Quantified Financial Benefits Statement, containing statements of estimated
    cost savings and synergies arising from the Combination, is set out below:

    The Wood Group Directors are confident that, as a direct result of the
    Combination, the Combined Group could generate attractive synergies and create
    additional shareholder value.

    The Original Announcement included statements of estimated pre-tax cost
    synergies expected to arise from the Combination of at least £110m per annum,
    by the end of the third year following Completion. On 5 April 2017, the Wood
    Group Directors updated an estimate of the pre-tax cost synergies expected to
    arise from the Combination from at least £110m per annum to at least £150m per
    annum by the end of the third year following Completion. The Wood Group
    Directors have now further increased their estimate of pre-tax cost synergies
    to at least £165m per annum, again by the end of the third year following
    Completion. In US$, the pre-tax cost synergies have increased from
    approximately US$134m per annum to approximately US$200m per annum, using the
    same US dollar:sterling exchange rate of 1.2171:1 as set out in the Original
    Announcement. The Wood Group Directors believe that these pre-tax cost
    synergies further enhance the attractiveness of the Combination.

    The increase in the expected level of pre-tax cost synergies is attributable to
    a more developed assessment of the synergy opportunity carried out since the
    Original Announcement, which has enabled a refinement of the synergy
    initiatives and the related risk adjustments incorporated in the underlying
    calculations.

    The expected sources of quantified cost synergies, which are in addition to
    synergies previously targeted and already underway by Wood Group and Amec
    Foster Wheeler separately, comprise:

      * operating efficiencies: approximately 50 per cent. of the identified cost
        synergies are expected to be generated from economies of scale in
        addressable operating cost, efficiencies in operational procurement spend
        and the reduction of duplicate costs across country and regional
        leadership;
       
      * corporate efficiencies: approximately 20 per cent. of the identified cost
        synergies are expected to be generated from the reduction of duplicate
        costs across board and executive leadership teams, in addition to other
        corporate and group functional costs; and
       
      * administration efficiencies: approximately 30 per cent. of the identified
        cost synergies are expected to be generated from the consolidation of
        overlapping office locations, the elimination of duplicated IT systems and
        the reduction of duplicate costs across central support functions.
       
        Approximately 30 per cent. of the identified cost synergies are expected to
        be realised by the end of the first year following Completion, rising to 70
        per cent. by the end of the second year following Completion and to 100 per
        cent. by the end of the third year following Completion.
       
        These anticipated cost synergies, which are reported under the City Code as
        set out in Appendix I of the Scheme Document, reflect both the beneficial
        elements and the costs, and will accrue as a direct result of the
        Combination and would not be achieved on a standalone basis.
       
        Wood Group estimates that realisation of these cost synergies would give
        rise to one-off costs of approximately £190 million (US$231 million)
        incurred in the first three years post-Completion.
       
        Aside from the one-off costs referred to above, the Wood Group Directors do
        not expect any material dis-synergies to arise in connection with the
        Combination.  Paragraph 17 of Part II of the Scheme Document describes the
        proposal of a remedy commitment that Wood Group has made to the CMA. Should
        such proposed remedy commitment be agreed with the CMA and implemented, it
        is anticipated that approximately £25m per annum of the pre-tax cost
        synergies would not be achieved. Furthermore, approximately £25m of the
        one-off costs to realise the cost synergies would not be incurred. In US$,
        the reduction in cost synergies would be approximately US$30m per annum and
        the reduction in one-off costs approximately US$30m, using the same US
        dollar:sterling exchange rate of 1.2171:1 as set out in the original
        announcement of the Combination on 13 March 2017.
       
        Over the longer term, the Wood Group Board believes that the Combined Group
        would also have the potential to realise additional revenue synergies that
        are not included in the Quantified Financial Benefits Statement, from the
        delivery of an expanded range of services to an enlarged customer base, a
        broader offering in the core oil and gas market, cross selling, pull
        through opportunities and insourcing by the Combined Group of currently
        outsourced activity.
       
        None of the statements contained above is intended as a profit forecast and
        should not be interpreted as such.
       
        Bases of belief
       
        In preparing the Quantified Financial Benefits Statement, Amec Foster
        Wheeler has provided Wood Group with certain operating and financial
        information to facilitate a detailed analysis in support of evaluating the
        potential synergies available from the Combination. In circumstances where
        data has been limited for commercial or other reasons, Wood Group
        management has made estimates and assumptions to aid its development of
        individual synergy initiatives.
       
        The cost base used as the basis for the quantified exercise is Amec Foster
        Wheeler's 2016 cost base, consistent with Amec Foster Wheeler's 2016
        unaudited full year trading update provided by Amec Foster Wheeler to Wood
        Group and released by Amec Foster Wheeler on 13 March 2017. Wood Group
        adjusted this information to take into account recent cost savings
        announced by Amec Foster Wheeler on 27 October 2016.
       
        The assessment and quantification of the expected synergies have in turn
        been informed by Wood Group management's industry experience as well as
        their experience of executing and integrating past acquisitions.
       
        In arriving at the estimate of synergies set out in this Announcement, the
        Wood Group Board has assumed that Amec Foster Wheeler's support function
        activities, such as Finance and Human Resources, will transition onto Wood
        Group's existing systems.
       
        In general, the synergy assumptions have in turn been risk adjusted,
        exercising a degree of prudence in the calculation of the estimated synergy
        benefit set out above.
       
        The Wood Group Board has, in addition, made the following assumptions, all
        of which are outside the influence of the Wood Group Board:
       
      * there will be no material impact on the underlying operations of either
        company or their ability to continue to conduct their businesses;
       
      * there will be no material change to macroeconomic, political, regulatory or
        legal conditions in the markets or regions in which Wood Group and Amec
        Foster Wheeler operate that materially impact on the implementation or
        costs to achieve the proposed cost savings;
       
      * there will be no material change in current foreign exchange rates; and
       
      * there will be no change in tax legislation or tax rates or other
        legislation or regulation in the countries in which Wood Group and Amec
        Foster Wheeler operate that could materially impact the ability to achieve
        any benefits.
       
        This analysis assumes no business disposal other than as referred to above.
       
        Reports
       
        As required by Rule 28.1(a) of the City Code, PwC, as reporting accountants
        to Wood Group, and J.P. Morgan Cazenove and Credit Suisse, as financial
        advisers to Wood Group, have provided the opinions required under that Rule
        relating to the Quantified Financial Benefits Statement set out above.
         Copies of these reports are set out below.  Any references to anticipated
        synergies should be read in conjunction with these reports. PwC, J.P.
        Morgan Cazenove and Credit Suisse have each given and have not withdrawn
        their consent to the publication of their respective report in the form and
        context in which it is included.
       
        Notes
       
        The statements of estimated synergies relate to future actions and
        circumstances which, by their nature, involve risks, uncertainties and
        contingencies. As a result, the synergies referred to may not be achieved,
        or may be achieved later or sooner than estimated, or those achieved could
        be materially different from those estimated.
       
        Due to the scale of the Combined Group, there may be additional changes to
        the Combined Group's operations. As a result, and given the fact that the
        changes relate to the future, the resulting synergies may be materially
        greater or less than those estimated.
       
        No statement in the Quantified Financial Benefits Statement or in this
        Announcement generally should be interpreted to mean that earnings,
        earnings per share or income, cash flow from operations or free cash flow
        for the Combined Group for the current or future financial years would
        necessarily match or exceed the historical published earnings, earnings per
        share or income, cash flow from operations or free cash flow for Wood
        Group, Amec Foster Wheeler or the Combined Group (as appropriate).

        Dear Ladies and Gentlemen,
       
        Updated Quantified Financial Benefits Statement by John Wood Group PLC
       
        We report on the quantified financial benefits statement (the "Statement")
        by the Directors included in the Scheme Document dated 23 May 2017 (the "
        Investment Circular") to the effect that:
       
        "The JWG Directors are confident that, as a direct result of the
        Combination, the Combined Group could generate attractive synergies and
        create additional shareholder value.
       
        The Announcement included statements of estimated pre-tax cost synergies
        expected to arise from the Combination of at least £110 million per annum
        by the end of the third year following completion of the Combination. On 5
        April 2017, the JWG Directors updated this estimate of the pre-tax cost
        synergies expected to arise from the Combination from at least £110 million
        per annum to at least £150 million per annum by the end of the third year
        following completion of the Combination. The JWG Directors have now further
        increased their estimate of pre-tax cost synergies to at least £165 million
        per annum by the end of the third year following completion of the
        Combination.
       
        In US dollars, the pre-tax cost synergies have increased from approximately
        US$134 million per annum to approximately US$200 million per annum, using
        the same US dollar:sterling exchange rate of 1.2171:1 as set out in the
        Announcement. The JWG Directors believe that these pre-tax cost synergies
        further enhance the attractiveness of the Combination.
       
        The increase in the expected level of pre-tax cost synergies is
        attributable to a more developed assessment of the synergy opportunity
        carried out since the Announcement, which has enabled a refinement of the
        synergy initiatives and the related risk adjustments incorporated in the
        underlying calculations.
       
        The expected sources of quantified cost synergies, which are in addition to
        synergies previously targeted and already underway by JWG and Amec Foster
        Wheeler separately, comprise:
       
        (i) operating efficiencies: approximately 50 per cent. of the identified
        cost synergies are expected to be generated from economies of scale in
        addressable operating cost, efficiencies in operational procurement spend
        and the reduction of duplicate costs across country and regional
        leadership;
       
        (ii) corporate efficiencies: approximately 20 per cent. of the identified
        cost synergies are expected to be generated from the reduction of duplicate
        costs across board and executive leadership teams, in addition to other
        corporate and group functional costs; and
       
        (iii) administration efficiencies: approximately 30 per cent. of the
        identified cost synergies are expected to be generated from the
        consolidation of overlapping office locations, the elimination of
        duplicated IT systems and the reduction of duplicate costs across central
        support functions.
       
        Approximately 30 per cent.of the identified cost synergies are expected to
        be realised by the end of the first year following completion of the
        Combination, rising to 70 per cent. by the end of the second year following
        completion of the Combination and to 100 per cent. by the end of the third
        year following completion of the Combination.
       
        These anticipated cost synergies, which are reported under the City Code as
        set out in Appendix I of this document, reflect both the beneficial
        elements and the costs, and will accrue as a direct result of the
        Combination and would not be achieved on a standalone basis.
       
        JWG estimates that realisation of these cost synergies would give rise to
        one-off costs of approximately £190 million (US$231 million) incurred in
        the first three years post-completion of the Combination.
       
        Aside from the one-off costs referred to above, the JWG Directors do not
        expect any material dis-synergies to arise in connection with the
        Combination. Paragraph 17 of this Part II of this document describes the
        proposal of a remedy commitment that JWG has made to the CMA. Should such
        proposed remedy commitment be agreed with the CMA and implemented, it is
        anticipated that approximately £25 million per annum of the pre-tax cost
        synergies would not be achieved. Furthermore, approximately £25 million of
        the one-off costs to realise the cost synergies would not be incurred. In
        US dollars, the reduction in cost synergies would be approximately US$30
        million per annum and the reduction in one-off costs approximately US$30
        million, using the same US dollar:sterling exchange rate of 1.2171:1 as set
        out in the Announcement."
       
        This Statement has been made in the context of disclosure in the Investment
        Circular setting out the bases of belief of the Directors supporting the
        Statement and their analysis and explanation of the underlying constituent
        elements.
       
        This report is required by Rule 28.1(a)(i) of the City Code on Takeovers
        and Mergers (the "Code") and is given for the purpose of complying with
        that rule and for no other purpose.
       
        Responsibilities
       
        It is the responsibility of the John Wood Group PLC Board to make the
        Statement in accordance with the Code.
       
        It is our responsibility to form our opinion as required by Rule 28.1(a)(i)
        of the Code, as to whether the Statement has been properly compiled on the
        basis stated.
       
        Save for any responsibility which we may have to those persons to whom this
        report is expressly addressed or to the shareholders of John Wood Group PLC
        as a result of the inclusion of this report in the Announcement, and for
        any responsibility arising under Rule 28.1(a)(i) of the Code to any person
        as and to the extent therein provided, to the fullest extent permitted by
        law we do not assume any responsibility and will not accept any liability
        to any other person for any loss suffered by any such other person as a
        result of, arising out of, or in connection with this report or our
        statement, required by and given solely for the purposes of complying with
        Rule 23.2(b) of the Code, consenting to its inclusion in the Investment
        Circular.
       
        Basis of Opinion
       
        We conducted our work in accordance with the Standards for Investment
        Reporting issued by the Auditing Practices Board in the United Kingdom. We
        have discussed the Statement together with the relevant bases of belief
        (including sources of information and assumptions) with the John Wood Group
        PLC Board and with the Financial Advisers. Our work did not involve any
        independent examination of any of the financial or other information
        underlying the Statement.
       
        Since the Statement and the assumptions on which it is based relate to the
        future and may therefore be affected by unforeseen events, we can express
        no opinion as to whether the actual benefits achieved will correspond to
        those anticipated in the Statement and the differences may be material.
       
        Our work has not been carried out in accordance with auditing or other
        standards and practices generally accepted in the United States of America
        or other jurisdictions and accordingly should not be relied upon as if it
        had been carried out in accordance with those standards and practices.
       
        Opinion
       
        In our opinion, on the basis of the foregoing, the Statement has been
        properly compiled on the basis stated.

    AB11 6EQ

    23 May 2017

    Dear Ladies and Gentlemen,

    Updated Quantified Financial Benefits Statement by John Wood Group PLC ("JWG")

    We refer to the quantified financial benefits statement, the bases of belief
    thereof and the notes thereto (together, the "Statement") made by JWG, set out
    in the scheme document dated 23 May 2017 (the "Scheme Document"), for which the
    Board of Directors of JWG (the "Directors") are solely responsible under Rule
    28.1(a)(ii) of the City Code on Takeovers and Mergers (the "Code").

    We have discussed the Statement (including the assumptions, accounting
    policies, bases of calculation and sources of information referred to therein),
    with the Directors and those officers and employees of JWG who have developed
    the underlying plans as well as with PricewaterhouseCoopers LLP.  The Statement
    is subject to uncertainty as described in the announcement and our work did not
    involve an independent examination of any of the financial or other information
    underlying the Statement.

    We have relied upon the accuracy and completeness of all the financial and
    other information provided to us by or on behalf of JWG and/or Amec Foster
    Wheeler, or otherwise discussed with or reviewed by us, and we have assumed
    such accuracy and completeness for the purposes of providing this letter.

    We do not express any view as to the achievability of the quantified financial
    benefits identified by the Directors.

    We have also reviewed the work carried out by PricewaterhouseCoopers LLP and
    have discussed with it its opinion addressed to you and us on this matter and
    which is set out in the Scheme Document, and the accounting policies and bases
    of calculation for the Statement.

    On the basis of the foregoing, we consider that the Statement, for which the
    Directors are solely responsible, for the purposes of the Code, has been
    prepared with due care and consideration.

    This letter is provided to you solely in connection with Rule 28.1(a)(ii) of
    the Code and for no other purpose.  We accept no responsibility to JWG, Amec
    Foster Wheeler or their shareholders or any person other than the Directors of
    JWG in respect of the contents of this letter.  We are acting exclusively as
    financial advisers to JWG and no one else in connection with the Combination
    between JWG and Amec Foster Wheeler and it was for the purpose of complying
    with Rule 28.1(a)(ii) of the Code that JWG requested J.P. Morgan Limited and
    Credit Suisse International to prepare this report on the Statement.  No person
    other than the Directors of JWG can rely on the contents of, or the work
    undertaken in connection with, this letter, and to the fullest extent permitted
    by law, we expressly exclude and disclaim all liability (whether in contract,
    tort or otherwise) to any other person, in respect of this letter, its contents
    or the work undertaken in connection with this letter or any of the results
    that can be derived from this letter or any written or oral information
    provided in connection with this letter.

    Yours faithfully,

    Cautionary Note Regarding Forward-Looking Statements

    This Announcement contains certain forward-looking statements with respect to
    the financial condition, results of operations and business of Amec Foster
    Wheeler and certain plans and objectives of Wood Group with respect thereto. 
    These forward-looking statements can be identified by the fact that they do not
    relate only to historical or current facts.  Forward-looking statements often
    use words such as "anticipate", "target", "expect", "estimate", "intend",
    "plan", "goal", "believe", "hope", "aims", "continue", "will", "may", "should",
    "would", "could", or other words of similar meaning.  These statements are
    based on assumptions and assessments made by Amec Foster Wheeler, and/or Wood
    Group in light of their experience and their perception of historical trends,
    current conditions, future developments and other factors they believe
    appropriate.  By their nature, forward-looking statements involve risk and
    uncertainty, because they relate to events and depend on circumstances that
    will occur in the future and the factors described in the context of such
    forward-looking statements in this Announcement could cause actual results and
    developments to differ materially from those expressed in or implied by such
    forward-looking statements.  Although it is believed that the expectations
    reflected in such forward-looking statements are reasonable, no assurance can
    be given that such expectations will prove to have been correct and you are
    therefore cautioned not to place undue reliance on these forward-looking
    statements which speak only as at the date of this Announcement.  Neither Amec
    Foster Wheeler nor Wood Group assumes any obligation to update or correct the
    information contained in this Announcement (whether as a result of new
    information, future events or otherwise), except as required by applicable law.

    There are several factors which could cause actual results to differ materially
    from those expressed or implied in forward-looking statements.  Among the
    factors that could cause actual results to differ materially from those
    described in the forward-looking statements are changes in the global,
    political, economic, business, competitive, market and regulatory forces,
    future exchange and interest rates, changes in tax rates and future business
    combinations or dispositions.

    Additional risk factors that may affect future results are contained in Amec
    Foster Wheeler's Form 20-F for the year ended 31 December 2016 (available at
    www.amecfw.com and www.sec.gov). These risk factors expressly qualify all
    forward-looking statements contained in this Announcement and should also be
    considered by the reader.

    For a discussion of important factors which could cause actual results to
    differ from forward-looking statements relating to Wood Group and the WG Group,
    refer to Wood Group's annual report and accounts for the year ended 31 December
    2016. Each forward-looking statement speaks only as of the date of this
    Announcement. None of Wood Group, the WG Group, Amec Foster Wheeler or the Amec
    Foster Wheeler Group undertakes any obligation to publicly update or revise any
    forward-looking statement as a result of new information, future events or
    otherwise, except to the extent legally required. In light of these risks,
    results could differ materially from those stated, implied or inferred from the
    forward-looking statements contained in this Announcement.

    Overseas jurisdictions

    The release, publication or distribution of this Announcement in jurisdictions
    other than the United Kingdom may be restricted by law and therefore any
    persons who are subject to the laws of any jurisdiction other than the United
    Kingdom should inform themselves about, and observe any applicable
    requirements. In particular, the ability of persons who are not resident in the
    United Kingdom to vote their Amec Foster Wheeler shares with respect to the
    Scheme at the Court Meeting, or to execute and deliver Forms of Proxy
    appointing another to vote at the Court Meeting on their behalf, may be
    affected by the laws of the relevant jurisdictions in which they are located.
    Any failure to comply with such requirements may constitute a violation of the
    securities laws of any such jurisdiction.  To the fullest extent permitted by
    applicable law, the companies and other persons involved in the Combination
    disclaim any responsibility or liability for any violation of such restrictions
    by any person.  This Announcement has been prepared for the purpose of
    complying with English law and the City Code and the information disclosed may
    not be the same as that which would have been disclosed if this Announcement
    had been prepared in accordance with the laws of jurisdictions outside the
    United Kingdom.  Unless otherwise determined by Wood Group or required by the
    City Code, and permitted by applicable law and regulation, the Combination will
    not be made available directly or indirectly in, into or from any Restricted
    Jurisdiction or where to do so would violate the laws of a jurisdiction, and
    the Combination will not be capable of acceptance from or within a Restricted
    Jurisdiction.

    Copies of this Announcement and any documentation relating to the Combination
    are not being, and must not be, directly or indirectly, mailed, transmitted or
    otherwise forwarded, distributed or sent in or into or from any Restricted
    Jurisdiction and persons receiving such documents (including custodians,
    nominees and trustees) must not mail or otherwise forward, distribute or send
    it in or into or from any Restricted Jurisdiction where to do so would violate
    the laws in that jurisdiction, and persons receiving this Announcement and any
    documents relating to the Combination (including custodians, nominees and
    trustees) must not mail or otherwise distribute or send them in, into or from
    such jurisdictions where to do so would violate the laws in that jurisdiction.

    If the Combination is implemented by way of an Offer (unless otherwise
    permitted by applicable law and regulation), the Offer may not be made directly
    or indirectly, in or into, or by the use of mails or any means or
    instrumentality (including, but not limited to, facsimile, e-mail or other
    electronic transmission, telex or telephone) of interstate or foreign commerce
    of, or of any facility of a national, state or other securities exchange of any
    Restricted Jurisdiction and the Offer may not be capable of acceptance by any
    such use, means, instrumentality or facilities.

    The availability of New Wood Group Shares under the Combination to Amec Foster
    Wheeler Shareholders who are not resident in the United Kingdom or the ability
    of those persons to hold such shares may be affected by the laws or regulatory
    requirements of the jurisdiction in which they are resident.  Persons who are
    not resident in the United Kingdom should inform themselves of, and observe,
    any applicable legal or regulatory requirements.

    The New Wood Group Shares may not be offered, sold or delivered, directly or
    indirectly, in, into or from any Restricted Jurisdiction or to, or for the
    account or benefit of, any restricted overseas persons (being any Amec Foster
    Wheeler Shareholders resident in, or nationals or citizens of, Restricted
    Jurisdictions or who are nominees or custodians, trustees or guardians for,
    citizens, residents or nationals of such Restricted Jurisdictions) except
    pursuant to an applicable exemption from, or in a transaction not subject to,
    applicable securities laws of those jurisdictions. Further details in relation
    to any Amec Foster Wheeler Shareholders who are resident in, ordinarily
    resident in, or citizens of, jurisdictions outside the United Kingdom, are
    contained in the Scheme Document.

    Additional information for US investors

    Notice to US investors in Amec Foster Wheeler: the Combination relates to the
    shares of an English company and is being made by means of a scheme of
    arrangement provided for under English company law.  A transaction effected by
    means of a scheme of arrangement is not subject to the tender offer rules or
    the proxy solicitation rules under the US Exchange Act, and it is expected that
    any New Wood Group Shares to be issued pursuant to the Scheme to Amec Foster
    Wheeler Shareholders would be issued in reliance upon the exemption from the
    registration requirements under the US Securities Act, provided by Section 3(a)
    (10) thereof. Under applicable US securities laws, persons (whether or not US
    persons) who are or will be "affiliates" (within the meaning of Rule 144 of the
    US Securities Act) of Amec Foster Wheeler or Wood Group prior to, or of Wood
    Group after, the Effective Date, will be subject to certain transfer
    restrictions relating to the New Wood Group Shares received in connection with
    the Combination. Accordingly, the Combination is subject to the disclosure
    requirements and practices applicable in the United Kingdom to schemes of
    arrangement which differ from the disclosure requirements of United States
    tender offer and proxy solicitation rules and the US Securities Act.  If, in
    the future, Wood Group exercises the right to implement the Combination by way
    of a takeover offer and determines to extend the offer into the United States,
    the Combination will be made in compliance with applicable United States laws
    and regulations, including any applicable exemptions under the US Exchange
    Act.  Financial information included in this Announcement and the Scheme
    Document has been or will have been prepared in accordance with accounting
    standards applicable in the United Kingdom that may not be comparable to
    financial information of US companies or companies whose financial statements
    are prepared in accordance with generally accepted accounting principles in the
    United States.

    The receipt of consideration by a US holder for the transfer of its Amec Foster
    Wheeler shares pursuant to the Scheme may be a taxable transaction for United
    States federal income tax purposes and under applicable United States state and
    local, as well as foreign and other, tax laws. Each Amec Foster Wheeler
    shareholder is urged to consult his independent professional adviser
    immediately regarding the tax consequences of the Combination applicable to
    him.

    It may be difficult for US holders of Amec Foster Wheeler shares to enforce
    their rights and any claim arising out of the US federal laws, since Wood Group
    and Amec Foster Wheeler are located primarily in a non-US jurisdiction, and
    some or all of their officers and directors may be residents of a non-US
    jurisdiction.  US holders of Amec Foster Wheeler shares may not be able to sue
    a non-US company or its officers or directors in a non-US court for violations
    of the US securities laws.  Further, it may be difficult to compel a non-US
    company and its affiliates to subject themselves to a US court's judgement.

    Securities issued pursuant to the Scheme will not be registered under any US
    state securities laws and may only be issued to persons resident in a state
    pursuant to an exemption from the registration requirements of the securities
    laws of such state.

    For the purpose of qualifying for the exemption provided by Section 3(a)(10) of
    the US Securities Act, Amec Foster Wheeler will advise the Court that its
    sanctioning of the Scheme will be relied on by Wood Group as an approval of the
    Scheme following a hearing on its fairness to Amec Foster Wheeler Shareholders,
    at which Court hearing all Amec Foster Wheeler Shareholders are entitled to
    attend in person or though counsel to support or oppose the sanctioning of the
    Scheme and with respect to which notification will be given to all such
    holders.

    In accordance with normal UK practice and, if applicable, pursuant to Rule
    14e-5(b) of the US Exchange Act, Wood Group or its nominees, or its brokers
    (acting as agents), may from time to time make certain purchases of, or
    arrangements to purchase, Amec Foster Wheeler shares outside of the US, other
    than pursuant to the Combination, until the date on which the Scheme becomes
    effective or lapses or is otherwise withdrawn.  In addition, in accordance with
    the City Code, normal United Kingdom market practice and Rule 14e-5(b) of the
    US Exchange Act, J.P. Morgan Cazenove and Credit Suisse, while serving as
    financial advisers and brokers to Wood Group, will each continue to act as
    exempt principal traders in Amec Foster Wheeler shares on the London Stock
    Exchange.  These purchases and activities by exempt principal traders, which
    may occur either in the open market at prevailing prices or in private
    transactions at negotiated prices, and are required to be made public in the
    United Kingdom pursuant to the City Code, will be reported to a Regulatory
    Information Service and will be available on the London Stock Exchange website
    at www.londonstockexchange.com.

    Quantified Financial Benefits Statement

    The statements in the Quantified Financial Benefits Statement relate to future
    actions and circumstances which, by their nature, involve risks, uncertainties
