Of these Exchangeable Bonds, £20,000 in principal amount have been exchanged under the terms of the Exchangeable Bonds for a pro rata share of the Exchange Property. In respect of £9,260,000 in principal amount of Exchangeable Bonds, BAE SYSTEMS has exercised its right under Condition 6(b) to purchase such Exchangeable Bonds at a purchase price equal to the Cash Value of the pro rata share of the Exchange Property. Accordingly, the aggregate principal amount of Exchangeable Bonds presently outstanding is £676,680,000. BAE SYSTEMS determined on 10th April, 2000, in accordance with the provisions of Condition 7(h) of the Exchangeable Bonds, that an adjustment should be made to the Exchange Rights under the terms of the Exchangeable Bonds to reflect the proposed sale of Mannesmann shares to Vodafone pursuant to the arrangements described above.

With immediate effect the Exchange Property has been adjusted so that it comprises 477,195,908 Vodafone shares. The Exchange Property per Exchangeable Bond is accordingly 7,052.017 Vodafone shares. 10th April, 2000 Issued by British Aerospace Public Limited Company
