Notification of Interests in Directors and Connected Persons - 
NICHOLAS KELVIN BROOKES and MY ENGU CHUNG

On 21 October 1996 Mr Brookes was granted 15,886 options over Ordinary shares of
3 1/3 pence each at the option price of 108.56 pence under the Company's Save As
You Earn Share Option Scheme (the 'Scheme'). The options granted were
exercisable in the six-month period up to 30 June 2002, however, Mr Brookes has
decided to allow the options to lapse.  Mr Brookes therefore no longer has an
interest in the 15,886 options under the Scheme. The total number of outstanding
options over Spirent Ordinary shares of 3 1/3p each held by Mr Brookes is now
1,910,135.

Also, on 1 July 2002 the Company was advised that Mr Chung had been allocated 58
Spirent American Depositary Receipts ('ADRs', one ADR is equal to four Ordinary
shares) following the re-investment in shares of the Company's final dividend
for 2001 to the participants in the Company's U.S. Employee Stock Purchase Plan.
The market value at the time of the purchase was $6.1076 per ADR. Mr Chung's
total holding of Spirent ADRs now stands at 2,086.
