                                (the "Company")                                

                          Director/PDMR Shareholding                           

Cubus Lux plc announces that, pursuant to the exercise of a share option
agreement dated 7 June 2004, it has allotted 210,000 ordinary shares of 1p each
in the Company for a consideration of 1p each to Eli Abramovich, a director of
the Company, conditional on the admission of these shares to trading on AIM.
Application has been made for the 210,000 shares to be admitted to AIM, which
is expected to become effective on 26 September 2007.

Following the above allotments, Mr Abramovich has an interest in 240,000
ordinary shares in the Company, representing 0.25 per cent. of the Company's
total voting rights. Mr Abramovich also has 1,000,000 share options, which were
issued on 27 April 2006, exercisable at a price of 10p and expiring on 26 April
2011.

The 30,000 ordinary shares of 1p each in the Company in which Mr Abramovich
held an interest prior to the exercise of options described above were acquired
on 30 November 2006 at a price of 19p, which purchase was not notified to the
market as a result of an error by the Company.

Following the issue of equity described above, the enlarged issued share
capital of the Company comprises 97,662,518 ordinary shares of 1p each.

The option agreement referred to above was granted on 7 June 2004, and provided
that the shares would vest in three equal tranches over three years, the last
of which on 7 June 2007. It also provided that the option would immediately
cease to be exercisable if not exercised in full by midnight on 7 June 2007. In
March 2007, the board of the Company extended the exercise period of this
option by three months as it believed that 7 June 2007 fell during a close
period which would preclude the exercise of the option. Mr Abramovich wrote to
the board in August 2007 to confirm his intention to exercise the option and
the board met on 20 September 2007 to approve the exercise and the allotment of
these shares.
