Barclays Recommended Merger with ABN AMRO – 30 Day Announcement

This announcement is being made pursuant to Dutch securities laws governing the Offer, more specifically article 9g paragraph 1under a of the Dutch Securities Market Supervision Decree (Besluit toezicht effectenverkeer 1995). In accordance with this article, within 30 calendar days after the announcement that was made by Barclays and ABN AMRO on 23 April 2007, an announcement must be made in order to update investors on the Offer.

Further to the announcement of 23 April 2007, outlining the terms of the agreed merger between Barclays PLC (“Barclays”) and ABN AMRO Holding N.V, (“ABN AMRO”), Barclays and ABN AMRO today announce that they are making excellent progress with the key regulatory filings required to proceed with Barclays offer to ABN AMRO shareholders (the “Offer”) and expect to publish Offer documentation in July.

Each of the Boards of ABN AMRO and Barclays has unanimously resolved to recommend the transaction to their shareholders. The proposed merger of ABN AMRO and Barclays will create a strong and competitive combination for its clients with superior products and extensive distribution. The merged group is expected to generate significant and sustained future incremental earnings growth for shareholders.

As set out in the joint Barclays and ABN AMRO announcement of 23 April 2007, ABN AMRO ordinary shareholders will receive 3.225 ordinary shares in Barclays for each existing ABN AMRO ordinary share. Under the terms of the Offer, Barclays existing ordinary shareholders will own approximately 52 per cent. and ABN AMRO existing ordinary shareholders will own approximately 48 per cent. of the combined group.

Regulatory Approvals

In connection with the Offer there are 108 regulatory authorities in 53 countries with whom a change of control filing needs to be made. A change of control consent is required from 55 of these regulatory authorities to enable closing of the Offer.





Barclays and ABN AMRO are making excellent progress in respect of these regulatory processes and by the end of May expect to have completed substantially all of the relevant filings where a consent or notification is required prior to closing of the public offer. The applications for the UK and the Netherlands, being the two most significant jurisdictions given the location of incorporation and lead regulation of the two groups, have already been filed with the relevant regulators.

Competition Authority Approvals

Barclays and ABN AMRO are also at an advanced state of preparation in relation to the various merger control filings that will be needed. The parties have jointly carried out a detailed competition analysis and are confident that there are no substantive anti-trust issues to address. Barclays and ABN AMRO therefore anticipate that merger control issues will not have any impact on the Offer timetable.

Timetable

The posting of formal Offer documentation remains conditional upon satisfaction or waiver of the pre-Offer conditions referred to in the announcement of 23 April 2007. Barclays and ABN AMRO intend to publish formal Offer documentation in six weeks.

Good progress has been made to date on fulfilment of significant pre-Offer conditions such as the regulatory and anti-trust filings referred to above, the required tax clearances, and the consultation with the representative bodies of the employees. Furthermore the UK Financial Services Authority (“FSA”) and De Nederlandsche Bank have agreed, as mentioned in the announcement of 23 April 2007, that the FSA will be lead supervisor of the combined group. However, significant matters still need to be progressed over the next six weeks, particularly in relation to regulatory approval of the Offer documentation by AFM, UKLA and SEC and the approval by the relevant US authorities required to complete the agreement with Bank of America to acquire LaSalle.

John Varley, the CEO of Barclays, said:

“Barclays recommended Offer for ABN AMRO will create a world leading bank, better able to serve our customers with more and better products thus creating additional value for the shareholders of both our companies for many years to come. The Barclays Offer provides ABN AMRO shareholders certainty, deliverability and value.”

This announcement is made in accordance with article 9g paragraph 1 under a of the Dutch Securities Market Supervision Decree (Besluit toezicht effectenverkeer 1995).
