    Recommended All-Share Offer by John Wood Group PLC for Amec Foster Wheeler plc 

                        Court sanction of Scheme of Arrangement                    

    On 13 March 2017, the boards of John Wood Group PLC ("Wood Group") and Amec
    Foster Wheeler plc ("Amec Foster Wheeler") announced that they had reached
    agreement on the terms of a recommended all-share offer by Wood Group for Amec
    Foster Wheeler (the "Combination") to be effected by means of a scheme of
    arrangement under Part 26 of the Companies Act 2006 (the "Scheme").

    Wood Group and Amec Foster Wheeler are pleased to announce that, at a hearing
    earlier today, the High Court of Justice in England and Wales sanctioned the
    Scheme.

    Delivery of the court order to the Registrar of Companies is expected to take
    place tomorrow, at which point the Scheme will become effective.

    The last day of dealings in, and for registration of transfers of, Amec Foster
    Wheeler Shares will be tomorrow, 6 October 2017. No transfers of Amec Foster
    Wheeler Shares will be registered after 6.00 p.m. tomorrow.

    Upon the Scheme becoming effective, Scheme Shareholders will receive 0.75 of a
    new ordinary share of 4 2/7 pence each in the capital of Wood Group in exchange
    for each Amec Foster Wheeler Share held by them at the Scheme Record Time,
    being 6.00 p.m. (BST) tomorrow, 6 October 2017. As at 4 October 2017, being the
    last business day prior to this announcement, the closing price of each Wood
    Group ordinary share was 700p.

    It is expected that the cancellation of the admission to trading of Amec Foster
    Wheeler Shares on the London Stock Exchange's Main Market for listed securities
    and the cancellation of the listing of Amec Foster Wheeler Shares from the
    premium segment of the Official List of the UK Listing Authority will each take
    place by 8.00 a.m. on 9 October 2017.

    Capitalised terms used but not otherwise defined in this announcement have the
    meanings given to them in the scheme document published on 23 May 2017 in
    relation to the Combination.

    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.

    Disclosure requirements of the Takeover Code (the "Code")

    Under Rule 8.3(a) of the Code, any person who is interested in 1% or more of
    any class of relevant securities of an offeree company or of any securities
    exchange offeror (being any offeror other than an offeror in respect of which
    it has been announced that its offer is, or is likely to be, solely in cash)
    must make an Opening Position Disclosure following the commencement of the
    offer period and, if later, following the announcement in which any securities
    exchange offeror is first identified. An Opening Position Disclosure must
    contain details of the person's interests and short positions in, and rights to
    subscribe for, any relevant securities of each of (i) the offeree company and
    (ii) any securities exchange offeror(s). An Opening Position Disclosure by a
    person to whom Rule 8.3(a) applies must be made by no later than 3.30 pm
    (London time) on the 10th business day following the commencement of the offer
    period and, if appropriate, by no later than 3.30 pm (London time) on the 10th
    business day following the announcement in which any securities exchange
    offeror is first identified. Relevant persons who deal in the relevant
    securities of the offeree company or of a securities exchange offeror prior to
    the deadline for making an Opening Position Disclosure must instead make a
    Dealing Disclosure.

    Under Rule 8.3(b) of the Code, any person who is, or becomes, interested in 1%
    or more of any class of relevant securities of the offeree company or of any
    securities exchange offeror must make a Dealing Disclosure if the person deals
    in any relevant securities of the offeree company or of any securities exchange
    offeror. A Dealing Disclosure must contain details of the dealing concerned and
    of the person's interests and short positions in, and rights to subscribe for,
    any relevant securities of each of (i) the offeree company and (ii) any
    securities exchange offeror, save to the extent that these details have
    previously been disclosed under Rule 8. A Dealing Disclosure by a person to
    whom Rule 8.3(b) applies must be made by no later than 3.30 pm (London time) on
    the business day following the date of the relevant dealing.

    If two or more persons act together pursuant to an agreement or understanding,
    whether formal or informal, to acquire or control an interest in relevant
    securities of an offeree company or a securities exchange offeror, they will be
    deemed to be a single person for the purpose of Rule 8.3.

    Opening Position Disclosures must also be made by the offeree company and by
    any offeror and Dealing Disclosures must also be made by the offeree company,
    by any offeror and by any persons acting in concert with any of them (see Rules
    8.1, 8.2 and 8.4).

    Details of the offeree and offeror companies in respect of whose relevant
    securities Opening Position Disclosures and Dealing Disclosures must be made
    can be found in the Disclosure Table on the Takeover Panel's website at
    www.thetakeoverpanel.org.uk, including details of the number of relevant
    securities in issue, when the offer period commenced and when any offeror was
    first identified. If you are in any doubt as to whether you are required to
    make an Opening Position Disclosure or a Dealing Disclosure, you should contact
    the Panel's Market Surveillance Unit on +44 (0)20 7638 0129.
