The Offer is being made on the terms and subject to the conditions contained in the tender offer memorandum dated 11 September 2017 (the Tender Offer Memorandum) prepared by the Company, and is subject to the offer restrictions set out below and as more fully described in the Tender Offer Memorandum.

For detailed terms of the Offer, please refer to the Tender Offer Memorandum, copies of which are (subject to distribution restrictions) available from the Tender Agent as set out below. Capitalised terms used in this announcement but not defined have the meanings given to them in the Tender Offer Memorandum.

Rationale for the Offer

The rationale for the Offer, and the intended issuance of New Capital Securities (as defined below), is to optimise the Company's cost of hybrid capital and balance sheet structure. The Company expects to finance the Offer from the partial proceeds of the intended issuance of New Capital Securities.

Under the terms and conditions of the Capital Securities, in the event that 80 per cent. or more of the aggregate principal amount of the Capital Securities have been purchased by the Company, its subsidiaries and/or its affiliates (pursuant to the Offer or otherwise), the Company may, at its option (subject to certain conditions), redeem all (but not some only) of the remaining Capital Securities at their principal amount together with any arrears of returns and any other accrued but unpaid periodic returns. As the Company is inviting Holders to tender any and all of the Capital Securities for purchase pursuant to the Offer, no assurance can be given that the 80 per cent. threshold described above will or will not be met following completion of the Offer and there can be no assurance, in the event that it is met, as to whether or when the Company will choose to exercise its option to redeem the Capital Securities. Any future decision by the Company to redeem the outstanding Capital Securities will depend on various factors existing at that time.

Capital Securities purchased by the Company pursuant to the Offer are expected to be cancelled and will not be re-issued or re-sold.
