                          Premier Energy and Water Trust PLC                       

                                          and                                      

                               PEWT Securities 2020 PLC                            

    The Board of Premier Energy and Water Trust PLC (the "Company") is pleased to
    announce that the name of the Company has changed to Premier Global
    Infrastructure Trust PLC in order to reflect a change of investment emphasis
    within the Company's portfolio. The name change has been registered at
    Companies House today and is effective immediately. The change will be
    reflected on the London Stock Exchange and trading in the Company's ordinary
    shares of 1 pence each will commence under the new trading instrument display
    mnemonic, "PGIT", from 8.00 a.m. on 2 November 2017.

    Simultaneously the name of the Company's subsidiary, PEWT Securities 2020 PLC,
    has been changed to PGIT Securities 2020 PLC and trading in its zero dividend
    preference shares of 1 pence each will commence under the new trading
    instrument display mnemonic, "PGIZ", from 8.00 a.m. on 2 November 2017.

    The Company's investment objectives, which remain unchanged, are to achieve a
    high income from and to realise long term growth in the capital value of its
    portfolio through investing principally in equity and equity related securities
    of companies operating primarily in the energy and water sectors as well as
    other infrastructure investments.

    The Company's energy and water investments represent a key infrastructure
    segment. The change of emphasis will involve an increase in exposure to
    non-utility infrastructure such as ports, toll roads and telecoms
    infrastructures.  Furthermore the UK content of the portfolio has over the last
    three years fallen from over 15% to under 10% and is expected to remain a
    relatively small part of the portfolio. The Board therefore consider the change
    of name to Premier Global Infrastructure Trust PLC will better reflect the
    positioning of the portfolio within its broader investment mandate which
    remains unchanged. The Directors are satisfied that the intended portfolio
    changes will not diminish the Company's ability to maintain and grow the
    dividend over the longer term.  

    No new share certificates are being issued in respect of existing ordinary
    shares of the Company or zero dividend preference shares of PEWT Securities
    2020 plc held in certificated form. Shareholders should retain their existing
    share certificates which will continue to be valid.
