Director/PDMR Shareholding

HAMPSON INDUSTRIES PLC

Notification of Director Shareholding

Hampson Industries PLC ('the Company') announces the following change to the interests of directors in the Company's ordinary shares ("Shares").

On 27 September 2011, pursuant to Listing Rule 9.4.2(2), one-off restricted stock awards were made to two directors of the Company, Norman Jordan and Ram Swamy, over 2,606,758 Shares and 1,463,443 Shares, respectively.

The award to Norman Jordan was made to facilitate Mr Jordan's retention as Chief Executive of the Company. The vesting of his award will be conditional on the Company successfully arranging material refinancing of its debt during the vesting period, in a form and to the extent determined by the Remuneration Committee to be sufficient in its absolute discretion.

The award to Ram Swamy was made to facilitate Mr Swamy's recruitment (on 13 June 2011) as Finance Director of the Company.

Each of the awards will normally vest during September 2014, provided that the director is still employed by the Company.

In addition, the Company announces that it has made awards under its Performance Share Plan and Co-Investment Plan to Norman Jordan over 2,606,758 ordinary shares and 506,856 ordinary shares respectively and an award under the Performance Share Plan to Ram Swamy over 1,463,443 ordinary shares

The shares comprised in these awards will only vest if the performance targets are satisfied as follows:

1. 50% of the award is dependent on the Company's relative total shareholder return ("TSR") performance compared with the TSR of those of a group of selected aerospace and specialist engineering companies. Shares are only receivable if the Company's TSR is above the median TSR compared with that peer group. If the Company's TSR performance is at or below median performance in the peer group, nothing will be received. If the Company's TSR performance is equal to the peer group median plus 13% per annum compound, full vesting will occur. For intermediate performance, vesting will occur on a straight-line basis.

2. 50% of the award will be based on the Company's earnings per share ("EPS"). If the growth in EPS over the performance period is less or equal to 5% per annum, nothing will be received. If the growth in EPS over the performance period is greater than or equal to 15% per annum, full vesting will occur. For intermediate performance, vesting will occur on a straight-line basis.

During the financial year 2010/2011, the Company implemented restructuring and improvement actions aimed at securing positive progress and improved results in the current and future years. The awards have been made to secure the executive team necessary to achieve these actions.

The awards will be satisfied by the transfer of existing Shares from the Company's Employee Benefit Trust ("EBT"). The EBT is a discretionary trust for the benefit of employees of the Company and its subsidiaries and is registered in the name of Kleinwort Benson (Jersey) Trustees Limited.

In accordance with Listing Rule 9.4.3, further details of the awards will be disclosed in the Company's Annual Report for the year ended 31 March 2012.

The notification of the awards is made in accordance Rule 3.1.4 of the Disclosure and Transparency Rules.
