    Recommended All-Share Offer by John Wood Group PLC ("Wood Group" or "JWG") for 
                    Amec Foster Wheeler plc ("Amec Foster Wheeler")                

                Wood Group completes acquisition of Amec Foster Wheeler            

    Wood Group is pleased to announce that it has completed the acquisition of Amec
    Foster Wheeler. Wood Group's new ordinary shares will be admitted to the
    premium segment of the Official List and to trading on the main market for
    listed securities of the London Stock Exchange with effect from 8.00 a.m.
    (London time) today, 9 October 2017.

    Robin Watson, Chief Executive of Wood Group commented:

    "This transformational acquisition creates a global leader in the delivery of
    project, engineering and technical services to energy and industrial markets.

    We become a business of significant scale and enhanced capability delivering
    services across a broader range of geographies and sectors, differentiated by
    the quality of our people, enabling technology and know-how.  Wood is better
    placed to serve customers than ever before, with a more comprehensive range of
    capabilities and the potential to deliver efficient integrated solutions with
    fewer customer interfaces.

    We expect to deliver significant cost synergies and incremental revenue
    synergies in a less cyclical business which retains a predominantly
    reimbursable, asset light model with a balanced risk appetite.

    Our integration planning is well progressed and we have ensured that
    appropriate risk management and control processes are in place from Day 1. We
    have a clear organisational structure, my Executive Leadership team and their
    direct reports have been announced and we are now focussing on implementing a
    best of both approach for the wider organisation. "

    Admission of new ordinary shares and cancellation of the listing of Amec Foster
    Wheeler shares

    Holders of ordinary shares of 50 pence each in the capital of Amec Foster
    Wheeler ("Amec Foster Wheeler Shares") on the register at the Scheme record
    time, being 6.00 p.m. on 6 October 2017, will receive 0.75 of an ordinary share
    of 4 2/7 pence each in the capital of Wood Group ("New JWG Shares") in exchange
    for each Amec Foster Wheeler Share. As a result, 294,510,216 New JWG Shares
    will be listed on the Premium Listing segment of the Official List of the UK
    Listing Authority and will be admitted to trading on the London Stock
    Exchange's main market from 8.00 a.m. today.

    Following the admission to trading of the New JWG Shares, the Wood Group's
    issued share capital will consist of 677,685,600 ordinary shares with each
    share carrying the right to one vote. Wood Group holds no ordinary shares in
    treasury. The total number of voting rights in Wood Group will therefore be
    677,685,600. This figure may be used by shareholders as the denominator for the
    calculations by which they will determine if they are required to notify their
    interest, or a change to their interest, in Wood Group under the FCA's
    Disclosure Guidance and Transparency Rules.

    The admission of Amec Foster Wheeler Shares to the premium segment of the
    Official List and to trading on the main market for listed securities of the
    London Stock Exchange will be cancelled with effect from 8.00 a.m. (London
    time) today.

    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 JWG and certain plans and objectives of the combined group. 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 JWG in light
    of its experience and its perception of historical trends, current conditions,
    future developments and other factors it believes 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 JWG 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.
