                                  SPIRENT PLC

             PROPOSED DIVESTMENT OF INTERESTS IN THE WAGO COMPANIES


Introduction

Spirent announces that members of the Spirent Group have entered into agreements
with members of the Hohorst family and companies controlled by them for the sale
of Spirent's 51 per cent interests in WAGO, its  interconnection  joint venture,
for a total  consideration  of GBP60.7 million  (comprising  EUR83.0 million and
CHF7.4 million) payable in cash, in full, on completion (the 'Divestment').

The Hohorst family is Spirent's joint venture partner in WAGO.  Members of and
companies controlled by the Hohorst family own the remaining 49 per cent
interests in WAGO and have joint management control rights with Spirent over the
WAGO business.  Established in 1974 between members of the Hohorst family and
Spirent, WAGO manufactures and markets a range of innovative electrical wire
interconnection and termination systems.  These products are marketed and sold
globally under the WAGO brand name.

In view of the size of the Divestment and since Spirent's interests in WAGO are
to be sold to members of the Hohorst family and companies controlled by them,
including Wolfgang Hohorst and Sven-Michael Hohorst, both of whom are directors
of certain of the companies comprised in the WAGO group (and are therefore
deemed to be related parties under the Listing Rules of the UK Listing
Authority), the Divestment is conditional, inter alia, on the approval of
Spirent's shareholders.  This will be sought at an Extraordinary General Meeting
of the Company to be held on 31 March 2003.

Information on the WAGO Companies

The WAGO companies comprise WAGO Kontakttechnik GmbH and WAGO-Verwaltungs GmbH,
both based in Germany (together with their respective subsidiaries, 'WAGO
Germany'), and WAGO Contact S.A., based in Switzerland, together with a number
of directly or indirectly owned subsidiary companies in Western and Eastern
Europe, North America, India and the Far East.  At 31 December 2002, WAGO had
operations in 16 countries and employed approximately 2,800 people worldwide.

Since 1974, WAGO has grown organically through international expansion and the
development of its product range.  WAGO's core business is the design,
manufacture and marketing of a wide range of innovative electrical wire
interconnection and termination systems featuring WAGO's spring or screwless
pressure technology.  WAGO's products are used in a broad range of applications
and industries, including ventilation and heating systems, machine tool
manufacture, building installations, automotive engineering, power supply, the
steel industry and the food industry.  The products are marketed globally under
the WAGO brand name and are sold either directly or through independent sales
agencies.

Members of the Hohorst family and Spirent have joint management control rights
over the WAGO companies.  Accordingly, and due to the requirements of Financial
Reporting Standard 9 in relation to associates and joint ventures, Spirent's
interests in WAGO are accounted for as a joint venture under the gross equity
method of accounting in the consolidated accounts of Spirent.

For the year to 31 December 2002, Spirent's attributable 51 per cent share of
WAGO's turnover was GBP75.6 million and Spirent's attributable 51 per cent share
of WAGO's profit after taxation was GBP4.0 million.  At 31 December 2002,
Spirent's attributable 51 per cent share of the net assets of the WAGO companies
amounted to GBP50.1 million.

Terms of the Divestment

Spirent has entered into a series of agreements for the sale of its interests in
the WAGO companies to members of the Hohorst family and companies  controlled by
them for a total cash  consideration  of  GBP60.7  million  (comprising  EUR83.0
million  for WAGO  Germany  and  Spirent's  nominal  holdings  in certain  other
companies  owned by the Hohorst family and CHF7.4 million for WAGO Contact S.A.)
payable in cash, in full, on completion.

Financial Effects of the Divestment and use of Proceeds

From   completion  of  the   Divestment,   the  income  derived  from  Spirent's
attributable share of WAGO will no longer be included in Spirent's  consolidated
financial statements.  The only contribution to Spirent's cashflow from WAGO for
the year to 31  December  2002 was a dividend  of GBP0.2  million  (2001  GBP1.6
million;  2000  GBP1.1  million).  Accordingly,  apart from the  proceeds of the
Divestment, the Divestment will not have a material effect on Spirent's cashflow
on an ongoing basis.

The  Divestment  requires  the  consent of the  holders of  Spirent's  US dollar
denominated  loan notes (the  'Loan  Notes')  and the  lenders  under  Spirent's
syndicated  multi-currency credit facility (the 'Syndicated Bank Facility').  In
addition, to provide the Spirent Group with an increase in the level of headroom
available in relation to certain of the financial  covenants,  amendments to the
terms of the Loan Notes and the Syndicated Bank Facility have been agreed. These
consents and amendments are  conditional on completion of the Divestment and the
application  of  the  proceeds,   net  of  any  tax  and  expenses,  to  pre-pay
approximately   GBP45.8  million  of  the  Loan  Notes  and  pay  an  associated
contractual make-whole amount of approximately GBP12.4 million.

Extraordinary General Meeting

A circular convening the Extraordinary General Meeting to approve the Divestment
and giving further information on the Divestment will be posted to shareholders
shortly.

The Extraordinary General Meeting will be held at Spirent House, Crawley
Business Quarter, Fleming Way, Crawley, West Sussex, RH10 9QL at 11.00 am on 31
March 2003.
