Notice of EGM

Spirent PLC
01 October 2004

                                                            836 - 1 October 2004

                                  SPIRENT PLC

NOTICE OF EXTRAORDINARY GENERAL MEETING IN RESPECT OF PROPOSED ELIMINATION OF 
                       DEFICIT IN DISTRIBUTABLE RESERVES 

Spirent plc (LSE: SPT; NYSE: SPM), a leading communications technology company,
today announces that it has initiated the process required to effect the
elimination of the deficit in its distributable reserves.

The proposal will involve the cancellation of the Company's share premium
account and capital redemption reserve (the 'Cancellation') in order to
eliminate the deficit in the Company's distributable reserves.  The Cancellation
is subject to shareholder approval at an Extraordinary General Meeting ('EGM')
to be held on 26 October 2004 and an order of the High Court.  The effect of the
Cancellation will be to put the Company in a position where it could pay
dividends out of future distributable profits.  However, the Company's current
borrowing terms prohibit it from paying a dividend until certain financial
requirements are satisfied.  No decision has been taken by the Board to resume
dividend payments and any decision to be taken in the future will be made after
due consideration of all relevant circumstances including trading conditions,
the availability of cash and any alternative opportunities.

A circular containing the Notice convening the EGM in respect of the
Cancellation has been sent to the Company's shareholders today.

Commenting, Anders Gustafsson, Chief Executive, said:

'We have been working towards putting the Company on a more conventional
financial footing and this process will enable Spirent to manage its capital
base more effectively.'

Two copies of the circular to shareholders, including the Notice of EGM and the
Form of Proxy, have been submitted to the UK Listing Authority and will shortly
be available for inspection at the UK Listing Authority's Document Viewing
Facility which is situated at:
