The Placing Shares, in all respects, rank pari passu with the Company's ordinary shares.

The final number of Placing Shares to be placed by the Sellers and the price at which the Placing Shares are to be placed will be agreed by the Bookrunner and the Sellers at the close of the bookbuild process and the results of the Placing will be announced as soon as practicable thereafter.
