    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.
