(f) Section 10.04(a) of the Base Indenture is hereby amended and restated in its entirety as follows:

“Section 10.04 Additional Amounts. (a) Unless otherwise specified in the terms of Dated Subordinated Debt Securities of a series in accordance with Section 3.01, the Company will pay any amounts to be paid by the Company on any series of Dated Subordinated Debt Securities without deduction or withholding for, or on account of, any and all present or future income, stamp and other taxes, levies, imposts, duties, charges, fees, deductions or withholdings (“Taxes”) now or hereafter imposed, levied, collected, withheld or assessed by or on behalf of the United Kingdom or any political subdivision or authority thereof or therein having the power to tax (each, a “Taxing Jurisdiction”), unless the deduction or withholding is required by law. Unless otherwise specified in the terms of the Dated Subordinated Debt Securities of a series in accordance with Section 3.01, if at any time a Taxing Jurisdiction requires the Company to deduct or withhold Taxes, the Company will pay the additional amounts of, or in respect of, any interest (but not principal or any premium) on such series of Dated Subordinated Debt Securities (“Additional Amounts”) that are necessary so that the net amounts in respect of interest paid to the Holders of such series of Dated Subordinated Debt Securities, after the deduction or withholding, shall equal the amounts in respect of interest which would have been payable in respect of such series of Dated Subordinated Debt Securities had no such deduction or withholding been required. However, the Company will not pay Additional Amounts for Taxes:

(i) that are payable because the Holder or the Beneficial Owner of the Dated Subordinated Debt Securities is a domiciliary, national or resident of, or engages in business or maintains a permanent establishment or is physically present in, a Taxing Jurisdiction requiring that deduction or withholding, or otherwise has some connection with the Taxing Jurisdiction other than the holding or ownership of the relevant Dated Subordinated Debt Securities, or the collection of any payment of, or in respect of any interest on, any Dated Subordinated Debt Securities of the relevant series;

(ii) that are payable because (except in the case of a winding up of the Company in England) the relevant Dated Subordinated Debt Securities are presented for payment in the United Kingdom;

(iii) that are payable because the relevant Dated Subordinated Debt Securities are presented for payment more than thirty (30) days after the date payment became due or was provided for, whichever is later, except to the extent that the Holder would have been entitled to the Additional Amounts on presenting the Dated Subordinated Debt Security for payment at the close of such thirty-day (30-day) period;

(iv) that are payable because the Holder or the Beneficial Owner of the relevant Dated Subordinated Debt Securities or the beneficial owner of any payment of, or in respect of, any interest on such Dated Subordinated Debt Securities failed to make any necessary claim or to comply with any certification, identification or other requirements concerning the nationality, residence, identity or connection with the Taxing Jurisdiction of such Holder, Beneficial Owner or beneficial owner, if such claim or compliance is required by statute, treaty, regulation or administrative practice of the Taxing Jurisdiction as a condition to relief or exemption from such Taxes; or

5

(v) if such Taxes would not have been so imposed, or would have been excluded pursuant to clauses (i) through (iv) above inclusive, if the beneficial owner of, or person ultimately entitled to obtain an interest in, such Dated Subordinated Debt Securities had been the Holder of such Dated Subordinated Debt Securities.

Whenever in this Dated Subordinated Debt Securities Indenture there is mentioned, in any context, the payment of any interest on, or in respect of, any Dated Subordinated Debt Security of any series, such mention shall be deemed to include mention of the payment of Additional Amounts provided for in this Section to the extent that, in context, Additional Amounts are, were or would be payable in respect thereof pursuant to the provisions of this Section and as if express mention of the payment of Additional Amounts (if applicable) were made in any provisions hereof where such express mention is not made.”

(g) Sections 11.02, 11.03, 11.04, 11.08(a) and 11.09(a) of the Base Indenture are hereby amended by replacing the reference to “thirty (30)” appearing therein by “fifteen (15).”

(h) Section 11.10 of the Base Indenture is hereby amended and restated in its entirety as follows:

“Section 11.10 Limitations on Redemption. Notwithstanding any other provision in this Dated Subordinated Debt Securities Indenture and unless otherwise provided as contemplated by Section 3.01 with respect to any series of Dated Subordinated Debt Securities, the Company may redeem any series of Dated Subordinated Debt Securities before their Stated Maturity (and give notice thereof to the Holders of the relevant Dated Subordinated Debt Securities) only if the Company has obtained the prior consent of the PRA and/or the Relevant U.K. Resolution Authority (in either case, if such consent is then required by the Capital Regulations) for the redemption of the Dated Subordinated Debt Securities. In addition, any such redemption of any series of Dated Subordinated Debt Securities shall be subject to the additional conditions set out in Section 11.13.”

(i) Section 11.12 of the Base Indenture is hereby amended and restated in its entirety as follows:

“Section 11.12 Condition to Repurchase. Unless otherwise provided as contemplated by Section 3.01 with respect to any series of Dated Subordinated Debt Securities, the Company or any member of the Group may purchase or otherwise acquire any Outstanding Dated Subordinated Debt Securities of any series at any price in the open market or otherwise in accordance with the Capital Regulations, and subject to the prior consent of the PRA and/or the Relevant U.K. Resolution Authority (in either case, if such consent is then required by the Capital Regulations). In addition, any such repurchase of Outstanding Dated Subordinated Debt Securities shall be subject to the additional conditions set out in Section 11.13.”

(j) A new Section 11.13 is hereby inserted into the Base Indenture as follows:

“Section 11.13 Additional Conditions Relating to Redemption and Repurchase of Dated Subordinated Debt Securities. Any early redemption or repurchase of a particular series of Dated Subordinated Debt Securities shall be subject to:

6

(a) one of the following conditions in (i) or (ii) below being met, as applicable to such Dated Subordinated Debt Securities, in each case, if and to the extent then required by the Capital Regulations:

(i) before or at the same time as such redemption or repurchase of the Dated Subordinated Debt Securities, the Company replaces such Dated Subordinated Debt Securities with “own funds instruments” of equal or higher quality at terms that are sustainable for the Company’s income capacity; or

(ii) the Company has demonstrated to the satisfaction of the PRA that its “own funds” and “eligible liabilities” would, following such redemption or repurchase, exceed the relevant requirements for its own funds and eligible liabilities laid down in U.K. CRD and in the U.K legislation that implemented EU Directive 2014/59/EU, as amended from time to time, by a margin that the PRA considers necessary.

(b) in the case of any such early redemption or repurchase of a particular series of Dated Subordinated Debt Securities before five years after the date of issuance of the relevant series of Dated Subordinated Debt Securities, one of the following conditions in (i), (ii), (iii) or (iv) below being met, in each case, if and to the extent then required by the Capital Regulations:

(i) in the case of redemption due to the occurrence of a change in the regulatory classification of the relevant Dated Subordinated Debt Securities that does or would be likely to result in their exclusion from own funds or reclassification as own funds of lower quality (A) the PRA considers such change to be sufficiently certain and (B) the Company demonstrates to the satisfaction of the PRA that such regulatory reclassification was not reasonably foreseeable at the time of the issuance of the relevant Dated Subordinated Debt Securities; or

(ii) in the case of redemption due to the occurrence of a Tax Event, the Company demonstrates to the satisfaction of the PRA that such Tax Event is material and was not reasonably foreseeable at the time of issuance of the relevant Dated Subordinated Debt Securities; or

(iii) before or at the same time as such redemption or repurchase of the relevant Dated Subordinated Debt Securities, the Company replaces such Dated Subordinated Debt Securities with own funds instruments of equal or higher quality at terms that are sustainable for the Company’s income capacity and the PRA has permitted that action on the basis of the determination that it would be beneficial from a prudential point of view and justified by exceptional circumstances; or

(iv) the relevant Dated Subordinated Debt Securities are repurchased for market making purposes.

Notwithstanding the conditions set out above, if, at the time of any such redemption or repurchase, the Capital Regulations permit the redemption or repurchase of a particular series of Dated Subordinated Debt Securities only after compliance with one or more alternative or additional pre-conditions to those set out above, the Company will comply with such other and/or, as appropriate, additional pre-condition(s).”

7

(k) Section 13.01(a) of the Base Indenture is hereby amended by adding “or the Trustee on behalf of the Holders of the Dated Subordinated Debt Securities,” after “Notwithstanding and to the exclusion of any other term of the Dated Subordinated Debt Securities or any other agreements, arrangements, or understandings between the Company and any Holder or Beneficial Owner of the Dated Subordinated Debt Securities” and before “by acquiring any Dated Subordinated Debt Securities, each Holder and Beneficial Owner of the Dated Subordinated Debt Securities acknowledges, accepts, agrees to be bound by, and consents to the exercise of, any U.K. Bail-in Power by the Relevant U.K. Resolution Authority”.
