Interest Payment Amounts (as defined in the Conditions) shall be payable subject to and in accordance with terms and conditions set out in the "Terms and Conditions of the Capital Securities" (the "Conditions") on the Prevailing Principal Amount (as defined in the Conditions) of the Capital Securities from (and including) the Issue Date to (but excluding) 21 October 2026 (the "First Reset Date") at a rate of 6.000 per cent. per annum. If the Capital Securities are not redeemed in accordance with the Conditions on or prior to the First Reset Date, Interest Payment Amounts shall continue to be payable from (and including) the First Reset Date subject to and in accordance with the Conditions at a fixed rate, to be reset on the First Reset Date and every six years thereafter, equal to the Relevant Six-Year Reset Rate (as defined in the Conditions) plus a margin of 5.597 per cent. per annum. Interest Payment Amounts will (subject to the occurrence of a Non-Payment Event (as defined in, and as more particularly provided in, Condition 6.1 (Interest Cancellation – Non-Payment Event))) be payable semi-annually in arrear on 21 April and 21 October in each year, commencing on 21 April 2021 (each, an "Interest Payment Date"). Payments on the Capital Securities will be made free and clear of, without withholding or deduction for, or on account of any present or future taxes, duties, assessments or governmental charges of whatever nature, imposed, levied, collected, withheld or assessed by or within the Tax Jurisdiction (as defined in the Conditions) (the "Taxes") to the extent described under Condition 12 (Taxation). All payments by the Issuer in respect of the Capital Securities shall be conditional upon satisfaction of the Solvency Conditions (as defined in the Conditions) and no bankruptcy order in respect of the Issuer having been issued by a court in the United Arab Emirates, as more particularly described in Condition 4 (Status and Subordination) (see, in particular, "Risk Factors – Factors which are material for the purpose of assessing the risks associated with the Capital Securities - The Capital Securities are subordinated, conditional and unsecured obligations of the Issuer"). If a Non-Viability Event (as defined in the Conditions) occurs, a Write-down (as defined in the Conditions) shall occur on the relevant Non-Viability Event Write-down Date (as defined in the Conditions), as more particularly described in Condition 10 (Write-down at the Point of Non-Viability). In such circumstances, the Capital Securities shall automatically be deemed to be irrevocably and unconditionally written-down by the relevant Write-down Amount (as defined in the Conditions) and, in the case of the Write-down Amount corresponding to the full Prevailing Principal Amount of the Capital Securities then outstanding, the Capital Securities shall be cancelled (see "Risk Factors – Factors which are material for the purpose of assessing the risks associated with the Capital Securities - The right to receive repayment of the principal amount of the Capital Securities and the right for any further interest will be permanently written-down upon the occurrence of a Non-Viability Event"). The Issuer may elect, in its sole discretion, and in certain circumstances shall be required, not to pay interest falling due on the Capital Securities. Any Interest Payment Amounts not paid as aforesaid will not accumulate and the holder of a Capital Security shall not have any claim in respect thereof. The Capital Securities are undated and have no final maturity. Unless the Capital Securities have previously been redeemed or purchased and cancelled as provided in the Conditions, the Capital Securities may, at the option of the Issuer, subject to the prior approval of the Regulator (as defined in the Conditions), be redeemed (in whole but not in part) at the Early Redemption Amount (as defined in the Conditions) on 21 April 2026 and on any date thereafter up to and including the First Reset Date or on any Interest Payment Date following the First Reset Date. In addition, the Capital Securities may, upon the occurrence of a Tax Event or Capital Event (each as defined in the Conditions), be redeemed (in whole but not in part) at the Tax Redemption Amount or the Capital Event Redemption Amount (each as defined in the Conditions), respectively, subject to the prior approval of the Regulator and subject to the Conditions. The payment obligations of the Issuer under the Capital Securities (i) constitute direct, unsecured, conditional (as described in Conditions 4.2(b) (Subordination of the Capital Securities) and 4.3 (Solvency Conditions)) and subordinated obligations of the Issuer that rank pari passu and without preference or priority amongst themselves; (ii) rank subordinate and junior to all Senior Obligations (as defined in the Conditions) (but not further or otherwise); (iii) rank pari passu with all Pari Passu Obligations (as defined in the Conditions); and (iv) rank in priority only to all Junior Obligations (as defined in the Conditions). Notwithstanding any other provisions in the Conditions, to the extent that any of the Solvency Conditions are not satisfied at the relevant time or if a bankruptcy order in respect of the Issuer has been issued by a court in the United Arab Emirates, all claims of the holders of the Capital Securities under the Capital Securities will be extinguished and the Capital Securities will be cancelled without any further payment to be made by the Issuer under the Capital Securities. Upon the occurrence of an Enforcement Event (as defined in the Conditions), any holder of the Capital Securities may give written notice to the Issuer at the specified office of the Fiscal Agent (as defined in the Conditions), effective upon the date of receipt thereof by the Fiscal Agent, that such Capital Security is due and payable, whereupon the same shall, subject to Condition 10 (Write down at the point of Non-Viability) and Condition 11.4 (Enforcement Events – Restrictions) become forthwith due and payable at its Early Redemption Amount (as defined in the Conditions), without presentation, demand, protest or other notice of any kind.
