Dear Shareholders and Depositary Interest Holders

2016 SCRIP DIVIDEND SCHEME – INTERIM DIVIDEND 2017

I am writing to confirm that following the announcement of the Company's results for the six-month period ended 30 June 2017, the Company intends to pay an interim dividend of 9.5p per ordinary share on 13 September 2017 to shareholders registered on 11 August 2017.

Following the resolution that was passed at the Annual General Meeting of the Company on 19 May 2016, the Directors are again offering a scrip dividend alternative in respect of any future interim or final dividends. If you would like to take up this offer then please complete the Scrip Dividend Mandate form and return it to our registrars at the address below by 18 August 2017. If you have previously elected for a scrip dividend then you do not need to take any further action. The terms and conditions of this Scrip Dividend Scheme are contained in the circular dated 14 April 2016 which is available to view on the Company's website www.hiscoxgroup.com (the 'Circular').

Scrip dividends are attractive because they enable shareholders and Depositary Interest Holders to increase their holding or interest in the Company in a simple manner without incurring any dealing costs. At the same time, the Company can retain more cash for reinvestment in its business, which would otherwise be paid as a dividend.

The tax treatment in respect of those shareholders who are resident (or in the case of individual shareholders, domiciled and resident) in the UK for UK tax purposes, who hold shares as investments and who are the absolute beneficial owners of shares and who take up new shares under the 2016 Scrip Dividend Scheme was described in paragraph 14 of the Circular. This only provides an outline of the UK tax implications for UK shareholders and your own tax treatment will depend on your individual circumstances. You are therefore recommended to seek advice from your solicitor, accountant or other professional adviser before taking any action.

Those shareholders who have completed a Scrip Mandate Form will automatically receive new ordinary shares in respect of any future interim or final dividends to the extent a scrip dividend alternative applies.

Accordingly we are now sending to those shareholders who have not previously elected to receive scrip dividends a Scrip Mandate Form. If you wish to receive future dividends in the form of shares and you have not previously elected to do so you should sign and return the Scrip Mandate Form to Capita Asset Services, Corporate Actions, The Registry, 34 Beckenham Road, Beckenham, Kent BR3 4TU, United Kingdom by the close of business on 18 August 2017. If you wish to receive your dividends in cash in the usual way, then you need take no action. If you have previously elected to receive dividends in the form of shares and now wish to change those instructions you should contact Capita Asset Services on 0371 664 0321*. Depositary Interest Holders should make an election via the CREST system.

In order to be effective Scrip Dividend Mandate forms must be received by no later than the date advised by the Company when a dividend is announced to the extent a scrip dividend alternative is then offered. Details of the expected timetable for any such dividend will be published at the same time as a dividend is announced. As indicated in the Circular the Company intends that the last date for electing for any scrip dividend under the 2016 Scrip Dividend Scheme and therefore for receipt of any Scrip Mandate Forms or an electronic election via the CREST system will be prior to the date on which the scrip reference share price is determined. As a result if you wish to receive future dividends in the form of shares and you have not previously elected to do so, you should sign and return a Scrip Mandate Form to Capita Asset Services as indicated above.

Yours faithfully

Jeremy Pinchin Company Secretary
