Director/PDMR Shareholding

Directors' Shareholding & Notification of Interests

Hampson Industries PLC ("the Company") announces that an award made to a Director of the Company, Howard Kimberley, under its Performance Share Plan in November 2008 which, having in part achieved its performance targets, has now partially vested. In order to cover income tax and national insurance payable on vesting, Mr Kimberley has sold ordinary shares of 25 pence each as detailed below:

In addition the Company has made awards under its Performance Share Plan to two directors of the Company, Norman Jordan and Howard Kimberley over 1,170,491 ordinary shares and 465,116 ordinary shares respectively.

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.
