Item 2.    Subject Company Information

(a)    Name and Address

        The issuer, Spirent plc ("Spirent" or the "Company"), is a company organized under the laws of England and Wales with its principal executive office at Spirent House, Crawley Business Quarter, Fleming Way, Crawley, West Sussex RH10 9QL, United Kingdom. The telephone number at that address is +44 (0) 1293 767 676. The information set forth in the Option Exchange Offer in the sections under the heading "Particulars of the Offer" entitled "11. Information concerning Spirent" is incorporated herein by reference.

(b)    Securities

        This Tender Offer Statement on Schedule TO relates to an offer by Spirent to exchange (the "Option Exchange Program" or "OEP") options to purchase an aggregate of 49,752,367 shares of the Company's Ordinary shares (or, if relevant, ADRs), whether vested or unvested, that have been granted under the Spirent Stock Option Plan, as amended (the "SSOP") and that are held by optionholders (excluding executive directors of the Company) who reside in the United States of America, Canada, France, Germany, Hong Kong, the Netherlands, Sweden or the United Kingdom and who are employed within Spirent's Communications group business ("Eligible Employees"). Eligible Employees who, as at the record date of August 15, 2003, hold outstanding options under the SSOP with an exercise price of £1.40 per share or greater ("Underwater Options") are eligible to participate in the OEP. Under the OEP, participants waive their Underwater Options in return for the grant of new options ("Replacement Options") to acquire shares in the Company (or, if relevant, ADRs). The Replacement Options will be granted under the amended SSOP, as set forth in Exhibit (d)(1) to this Schedule TO. As at August 6, 2003, there were Underwater Options outstanding (whether vested or unvested) in respect of 49,752,367 Ordinary shares of the Company. Underwater Options may be exchanged for Replacement Options, upon the terms and subject to the conditions set forth in (i) the Option Exchange Offer and (ii) the Option Election Agreement. These documents, as they may be amended or supplemented from time to time, are attached to this Schedule TO as Exhibits (a)(1)(i) and (a)(1)(ii), respectively. In order to participate in the OEP, Eligible Employees must be employed continuously by the Company, from the date of this Option Exchange Offer through the date on which the Replacement Options are granted. The actual number of Ordinary shares to be issued under the OEP depends on the number of Ordinary shares subject to Underwater Options tendered by Eligible Employees and which are accepted for exchange.
