Block Listing Applications

Further to the announcement on 28 July 2017 regarding the completion of its refinancing, Premier provides notification that two block listing applications have been made for a total of 82,615,928 ordinary shares of 12.5 pence each in the Company to be admitted to the Official List and to trading on the London Stock Exchange's main market for listed securities.

The shares will be issued from time to time to satisfy the exercise of outstanding warrants issued as part of the refinancing:

· Up to 64,518,909 ordinary shares in the Company pursuant to the issue of equity warrants to its Private Lenders and Retail Bondholders; and

· Up to 18,097,019 ordinary shares in the Company pursuant to the issue of equity warrants to its Convertible Bondholders.

Holders of equity warrants may elect for cashless exercise of all or any number of their equity warrants, in which case, the number of shares issued on exercise shall be reduced accordingly to account for the exercise price which would otherwise have been paid.

When issued, these shares will rank pari passu in all respects with all existing ordinary shares in the Company. It is expected that admission will become effective on 10 August 2017.

Following the admission of these shares, the exercise of equity warrants will be covered by a block listing. The Company will provide updates regarding the total number of shares in issue and the number of warrants outstanding at the end of each month and at other such times as required by the Listing Rules.
