Proposed Exchange of A&L Preference Shares for New Santander UK Preference Shares

Posting of Scheme Document and Prospectus

On 26 February 2010, A&L and Santander UK announced that the holders of the Series A Fixed/Floating Rate Non-Cumulative Callable Preference Shares of A&L (the "A&L Preference Shares") (ISIN XS0254788515) would be given the opportunity to exchange their A&L Preference Shares for new preference shares to be issued by Santander UK (the "New Santander UK Preference Shares") by means of a scheme of arrangement under Part 26 of the Companies Act 2006 (the "Preference Scheme").

A&L and Santander UK today announce that the following documents were posted to the registered holders of the A&L Preference Shares and the registered holders of A&L ordinary shares on 12 March 2010:

(i) the scheme document (the "Scheme Document") setting out the terms of the Preference Scheme and containing notices calling a court-convened meeting of the holders of the A&L Preference Shares, a general meeting of A&L, and a class meeting of holders of A&L Preference Shares (the "Meetings"); and

(ii) the prospectus issued by Santander UK in relation to the New Santander UK Preference Shares (the "Prospectus").

If all of the conditions to the Preference Scheme (which will include approval by holders of the A&L Preference Shares, holders of the A&L ordinary shares and the Court) are satisfied or, where applicable, waived, the Preference Scheme is expected to become effective on 28 April 2010 (the "Effective Date").

If you hold A&L Preference Shares through Euroclear or Clearstream in uncertificated form and wish to vote in respect of the Preference Scheme, Electronic Voting Instructions must be delivered to the Tabulation Agent through and in accordance with the procedures of Euroclear and Clearstream by 5.00 p.m. (London time) on Friday 26 March 2010 (or such earlier deadline as may be specified by Euroclear or Clearstream). Please refer to the Scheme Document for more details about the procedure for delivering Electronic Voting Instructions.

The Meetings will be held at 2 Triton Square, Regent's Place, London NW1 3AN on 30 March 2010. The court meeting of A&L Preference Shareholders will be held at 8:45 a.m., the general meeting of A&L at 8:50 a.m. (or as soon as the court meeting has been concluded or adjourned) and the class meeting of holders of A&L Preference Shares at 8:55 a.m. (or as soon as the court meeting and the general meeting have been concluded or adjourned).

The results of each meeting will be publicly announced via a Regulatory Information Service as soon as is practicable following the meeting, and by no later than 8.00 a.m. on the business day following the meeting.
