NEWMARK SECURITY PLC ('NEWMARK')

ALL SHARE OFFER FOR VEMA N.V. (THE 'OFFER')

OFFER DECLARED WHOLLY UNCONDITIONAL

Following a meeting of the board, Newmark announces that all of the conditions
of the Offer have now been satisfied or waived and consequently the Offer has
been declared unconditional in all respects.

As at 3.00 pm on 16 September 2002, valid acceptances had been received in
respect of 47,288,220 Vema N.V. ('Vema') GDRs, representing in aggregate,
approximately 65.67 per cent. of the Vema shares not already owned by Newmark.
Taking into account the 51 per cent. of Vema already owned by Newmark, Newmark
effectively controls approximately 83 per cent. of Vema's shares.

Following the Offer being declared unconditional today, the acquisition of
Grosvenor Technology Limited is expected to be completed on 19 September 2002.
Following this reverse takeover, trading in Newmark's shares on the Alternative
Investment Market of the London Stock Exchange plc ('AIM') will be cancelled on
19 September and the enlarged share capital of Newmark will be admitted to AIM
on 20 September 2002.

The Offer will remain open for acceptance until further notice.  Vema GDR
holders who wish to accept the Offer, but have not yet done so, are strongly
encouraged to return their completed Forms of Acceptance (and supporting
documents) as soon as possible.  Further Forms of Acceptance are available from
Capita IRG, Bourne House, Beckenham Road, Kent BR3 4TH (telephone number 0870
1623100).

The attention of Vema GDR holders is drawn to the fact that, as stated in the
Offer Document, the Offer having been declared unconditional, Vema intends to
apply for the de-listing of its GDRs from AIM.

The Offer is not being made, directly or indirectly, in or into, and may not be
accepted in or from, the United States, Canada, Australia or Japan.
Accordingly, copies of this announcement are not being, and must not be, mailed,
forwarded, transmitted or otherwise distributed or sent in, into or from the
United States, Canada, Australia or Japan.
