Any person subsequently offering, selling or recommending the Notes (a "distributor") should take into consideration the manufacturer's target market assessment; however, a distributor subject to MiFID II is responsible for undertaking its own target market assessment in respect of the Notes (by either adopting or refining the manufacturer's target market assessment) and determining appropriate distribution channels.
U.K. MiFIR PRODUCT GOVERNANCE / PROFESSIONAL INVESTORS AND ECPs ONLY TARGET MARKET - Solely for the purposes of each manufacturer's product approval process, the target market assessment in respect of the Notes has led to the conclusion that: (i) the target market for the Notes is only eligible counterparties, as defined in the FCA Handbook Conduct of Business Sourcebook ("COBS"), and professional clients, as defined in Regulation (EU) No 600/2014 as it forms part of domestic law by virtue of the European Union (Withdrawal) Act 2018 ("U.K. MiFIR"); and (ii) all channels for distribution of the Notes to eligible counterparties and professional clients are appropriate. Any person subsequently offering, selling or recommending the Notes (a "distributor") should take into consideration each manufacturer's target market assessment; however, a distributor subject to the FCA Handbook Product Intervention and Product Governance Sourcebook (the "U.K. MiFIR Product Governance Rules") is responsible for undertaking its own target market assessment in respect of the Notes (by either adopting or refining each manufacturer's target market assessment) and determining appropriate distribution channels.
ADB does not fall under the scope of application of MiFID II or U.K. MiFIR. Consequently, ADB does not qualify as an "investment firm", "manufacturer" or "distributor" for the purposes of either MiFID II or U.K. MiFIR.

ANNEX
A.
Provisions relating to the determination of the Rate of Interest

The Rate of Interest for each relevant Interest Period shall be determined by the Calculation Agent on each Interest Determination Date in accordance with the following provisions. The Rate of Interest for each Interest Period shall apply with effect from the Reset Date for that Interest Period.

The "Rate of Interest" means for each Interest Period, subject as provided below, the Compounded SOFR plus the Margin.

"Interest Period" means each period from, and including, each Interest Payment Date (or, in the case of the first Interest Period, the Interest Commencement Date) to, but excluding, the next Interest Payment Date (or, in the case of the final Interest Period, the Maturity Date), or in the case of the Notes becoming due and payable, the date on which the Notes become due and payable. In each case, as adjusted in accordance with the relevant Business Day Convention.

"SOFR" means the daily secured overnight financing rate as provided by the SOFR Administrator on the SOFR Administrator's Website (currently at https://www.newyorkfed.org/markets/reference-rates/sofr).

"SOFR Administrator" means the Federal Reserve Bank of New York as administrator of SOFR (or any successor administrator of SOFR or the SOFR Index).

"SOFR Administrator's Website" means the website of the SOFR Administrator, or any successor source.

"Compounded SOFR" means, for any Interest Period and subject to the Compounded SOFR Fallback Provisions set out below, the rate determined by the Calculation Agent on each Interest Determination Date calculated in accordance with the formula below and the resulting percentage being rounded, if necessary, to the nearest one hundred-thousandth of a percentage point, with 0.000005 being rounded upwards (e.g., 9.876541% (or 0.09876541) being rounded down to 9.87654% (0.0987654) and 9.876545% (or 0.09876545) being rounded up to 9.87655% (or 0.0987655):


where:

"Observation Period" means, in respect of each Interest Period, the period from, and including, the date which is five U.S. Government Securities Business Days preceding the first date of such Interest Period to, but excluding, the date which is five U.S. Government Securities Business Days preceding the Interest Payment Date for such Interest Period (or in the final Interest Period, the Maturity Date).

9
"SOFR IndexStart" means the SOFR Index value on the day which is five U.S. Government Securities Business Days preceding the first date of the relevant Interest Period.

"SOFR IndexEnd" means the SOFR Index value on the day which is five U.S. Government Securities Business Days preceding the Interest Payment Date relating to such Interest Period (or in the final Interest Period, the Maturity Date).

"dc" means the number of calendar days in the Observation Period relating to such Interest Period.

"SOFR Index", with respect to any U.S. Government Securities Business Day, means:

(1)
the SOFR Index value as published by the SOFR Administrator as such index appears on the SOFR Administrator's Website (currently at https://apps.newyorkfed.org/markets/autorates/sofr-avg-ind) on or about 3:00 p.m. (New York time) on such U.S. Government Securities Business Day (the "SOFR Index Determination Time"); provided that in the event that the value originally published by the SOFR Administrator on or about 3:00 p.m. (New York time) on any U.S. Government Securities Business Day is subsequently corrected and such corrected value is published by the SOFR Administrator on the original date of publication, then such corrected value, instead of the value that was originally published, shall be deemed the SOFR Index as of the SOFR Index Determination Time in relation to such U.S. Government Securities Business Day; and


(2)
if a SOFR Index value does not so appear as specified in (1) above, then:


a.
if a Benchmark Transition Event and its related Benchmark Replacement Date have not occurred with respect to SOFR, then Compounded SOFR shall be the rate determined pursuant to the "SOFR Index Unavailable" provisions; or


b.
if a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to SOFR, then Compounded SOFR shall be the rate determined pursuant to the "Effect of a Benchmark Transition Event" provisions.

"Reset Date" means the first day of each Interest Period.

"U.S. Government Securities Business Day" means any day other than a Saturday, a Sunday or a day on which the Securities Industry and Financial Markets Association ("SIFMA") recommends that the fixed income departments of its members be closed for the entire day for purposes of trading in U.S. government securities.

10
B.
Compounded SOFR Fallback Provisions

SOFR Index Unavailable:

If a SOFR IndexStart or SOFR IndexEnd is not published on the associated Interest Determination Date and a Benchmark Transition Event and its related Benchmark Replacement Date have not occurred with respect to SOFR Index or SOFR, then "Compounded SOFR" means, for the applicable Interest Period for which such index is not available, the rate of return on a daily compounded interest investment calculated by the Calculation Agent in accordance with the formula for SOFR Averages, and definitions required for such formula, published on the SOFR Administrator's Website at https://www.newyorkfed.org/markets/treasury-repo-reference-rates-information. For the purposes of this provision, references in the SOFR Averages compounding formula and related definitions to "calculation period" shall be replaced with "Observation Period" and the words "that is, 30-, 90-, or 180- calendar days" shall be removed. If the daily SOFR ("SOFRi") does not so appear for any day, "i" in the Observation Period, SOFRi for such day "i" shall be the SOFR published in respect of the first preceding U.S. Government Securities Business Day for which SOFR was published on the SOFR Administrator's Website.

Effect of a Benchmark Transition Event:

If ADB determines on or prior to the relevant Reference Time that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to the then-current Benchmark, the Benchmark Replacement will replace the then-current Benchmark for all purposes relating to the Notes in respect of all determinations on such date and for all determinations on all subsequent dates.

In connection with the implementation of a Benchmark Replacement, ADB will have the right to make Benchmark Replacement Conforming Changes from time to time.

Any determination, decision or election that may be made by ADB pursuant to this section, including any determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action or any selection:


(1)
will be conclusive and binding absent manifest error;

(2)
will be made in the sole discretion of ADB; and

(3)
notwithstanding anything to the contrary in the documentation relating to the Notes described herein, shall become effective without consent from the holders of the Notes or any other party.

"Benchmark" means, initially, SOFR Index; provided that if ADB determines on or prior to the Reference Time that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to SOFR Index (or the published daily SOFR used in the calculation thereof) or the then-current Benchmark, then "Benchmark" means the applicable Benchmark Replacement.

11
"Benchmark Replacement" means the first alternative set forth in the order below that can be determined by ADB as of the Benchmark Replacement Date:


(1)
the sum of: (a) the alternate rate of interest that has been selected or recommended by the Relevant Governmental Body as the replacement for the then-current Benchmark and (b) the Benchmark Replacement Adjustment;

(2)
the sum of: (a) the ISDA Fallback Rate and (b) the Benchmark Replacement Adjustment; or

(3)
the sum of: (a) the alternate rate of interest that has been selected by ADB as the replacement for the then-current Benchmark giving due consideration to any industry-accepted rate of interest as a replacement for the then-current Benchmark for U.S. dollar-denominated floating rate notes at such time and (b) the Benchmark Replacement Adjustment.

"Benchmark Replacement Adjustment" means the first alternative set forth in the order below that can be determined by ADB as of the Benchmark Replacement Date:


(1)
the spread adjustment, or method for calculating or determining such spread adjustment, (which may be a positive or negative value or zero) that has been selected or recommended by the Relevant Governmental Body for the applicable Unadjusted Benchmark Replacement;

(2)
if the applicable Unadjusted Benchmark Replacement is equivalent to the ISDA Fallback Rate, the ISDA Fallback Adjustment; or

(3)
the spread adjustment (which may be a positive or negative value or zero) that has been selected by ADB giving due consideration to any industry-accepted spread adjustment, or method for calculating or determining such spread adjustment, for the replacement of the then-current Benchmark (or the daily published component used in the calculation thereof) with the applicable Unadjusted Benchmark Replacement for U.S. dollar-denominated floating rate notes at such time.

"Benchmark Replacement Conforming Changes" means, with respect to any Benchmark Replacement, any technical, administrative or operational changes (including changes to the timing and frequency of determining rates and making payments of interest, rounding of amounts or tenors, and other administrative matters) that ADB decides may be appropriate to reflect the adoption of such Benchmark Replacement in a manner substantially consistent with market practice (or, if ADB decides that adoption of any portion of such market practice is not administratively feasible or if ADB determines that no market practice for use of the Benchmark Replacement exists, in such other manner as ADB determines is reasonably necessary).

"Benchmark Replacement Date" means the earliest to occur of the following events with respect to the then-current Benchmark (or the daily published component used in the calculation thereof):


(1)
in the case of clause (1) or (2) of the definition of "Benchmark Transition Event," the later of (a) the date of the public statement or publication of information referenced therein and (b) the date on which the administrator of the Benchmark permanently or indefinitely ceases to provide the Benchmark (or such component); or

12

(2)
in the case of clause (3) of the definition of "Benchmark Transition Event," the later of (a) the date of the public statement or publication of information referenced therein and (b) the first date on which such Benchmark (or such component) is no longer representative per such statement or publication.

For the avoidance of doubt, if the event that gives rise to the Benchmark Replacement Date occurs on the same day as, but earlier than, the Reference Time in respect of any determination, the Benchmark Replacement Date will be deemed to have occurred prior to the Reference Time for such determination.

"Benchmark Transition Event" means the occurrence of one or more of the following events with respect to the then-current Benchmark (or the daily published component used in the calculation thereof):


(1)
a public statement or publication of information by or on behalf of the administrator of the Benchmark (or such component) announcing that such administrator has ceased or will cease to provide the Benchmark (or such component), permanently or indefinitely, provided that, at the time of such statement or publication, there is no successor administrator that will continue to provide the Benchmark (or such component); or


(2)
