such reduction, the aggregate amount of capital held by the Group as of the first Balance Sheet Date immediately following receipt of the relevant Reduction Confirmation that qualifies as Progressive Capital Component as of such Balance Sheet Date
exceeds the relevant Reduced Minimum Progressive Capital Component Requirement.

| | (iii) | An Alignment Event shall be deemed to have occurred if, as the result of any change in the National Regulations at any time after the Issue Date, any Relevant Swiss Issuer would be permitted to issue,
or has issued, a capital instrument that (A) qualifies as Tier 2 Capital and Progressive Capital Component, and (B) has terms and conditions that (x) include a write-down feature, and (y) contain one or more provisions that are,
in the reasonable opinion of the Issuer, different in any material respect from those in these Terms and Conditions, which provisions, if they had been included in these Terms and Conditions, would have prevented the Notes from qualifying as Tier 2
Capital and Progressive Capital Component immediately prior to such change in the National Regulations.

For the avoidance of doubt, it is understood
that, if, upon the occurrence of a Tax Event, Regulatory Event, Change in Progressive Capital Component Requirement or Alignment Event, the Issuer does not elect to early redeem the Notes pursuant to this Condition 5, nothing in this Condition 5

|6. | CONTINGENT WRITE-DOWN
|-- | ---------------------



| | (a) | Trigger Event
| | --- | -------------



| | (i) | Upon the occurrence of a Trigger Event, a Contingent Write-down shall occur on the Trigger Event Write-down Date in accordance with clause (d) of this Condition 6.

immediately preceding such Publication Date, except
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



43

| | pursuant to the conversion of a security into, or the exchange of a security for, any Core Capital Instruments, or as a Permitted Transaction,
| | ----------------------------------------------------------------------------------------------------------------------------------------------

the Issuer shall, subject to clauses (b)(ii) and (b)(iii) of this Condition 6, give a Trigger Event Write-down Notice to the Holders
(x) if such Publication Date is an Ordinary Publication Date, within five Business Days of such Publication Date (such fifth Business Day, the Trigger Breach Determination Date, and the date of such notice, the
Ordinary Trigger Event Notice Date), and (y) if such Publication Date is an Extraordinary Publication Date, on such Publication Date (the Extraordinary Trigger Event Notice Date), in each case in accordance
with Condition 12 (Notices).



| | (ii) | If the Issuer is required to give a Trigger Event Write-down Notice pursuant to clause (b)(i) of this Condition 6, and on the relevant Publication Date any High-Trigger Contingent Capital is outstanding with respect to
which either (x) no High-Trigger Write-down/Conversion Notice has been given prior to the Trigger Event Notice Date or (y) a High-Trigger Write-down/Conversion Notice has been given prior to the Trigger Event Notice Date, but the Trigger
Event Write-down Date is scheduled to occur prior to the relevant High-Trigger Write-down/Conversion Date,
| | ---- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (A) | in the case of clause (x) above, the Issuer shall postpone giving such Trigger Event Write-down Notice until the date on which a High-Trigger Write-down/Conversion Notice has been given with respect to all such
outstanding High-Trigger Contingent Capital and such date shall be deemed to be the Trigger Event Notice Date; and
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (B) | in the case of clauses (x) and (y) above, if the Trigger Event Write-down Date is scheduled to occur prior to the High-Trigger Write-down/Conversion Date (or, in the case of more than one High-Trigger
Write-down/Conversion Date, the latest High-Trigger Write-down/Conversion Date), the Trigger Event Write-down Date shall be postponed to the High-Trigger Write-down/Conversion Date (or the latest High-Trigger Write-down/Conversion Date, as
applicable) and such postponement shall be specified in such Trigger Event Write-down Notice.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | If (A) the Issuer is required to give a Trigger Event Write-down Notice pursuant to clause (b)(i) of this Condition 6 in relation to an Ordinary Publication Date, and (B) prior to the earlier of the Ordinary
Trigger Event Notice Date and the Trigger Breach Determination Date, the FINMA, upon the request of UBS AG, has agreed in writing that a Contingent Write-down is not required as a result of actions taken by the Group or circumstances or events, in
each case, that have had, or imminently will have, the effect of restoring the CET1 Ratio as of the Balance Sheet Date relating to the relevant Ordinary Publication Date, after giving pro forma effect to such actions, circumstances or events, to a
level above the Write-down Threshold that the FINMA and UBS AG deem, in their sole discretion, to be adequate at such time, the Issuer (x) shall not give such Trigger Event Write-down Notice pursuant to clause (b)(i) of this Condition 6 in
relation to the relevant Ordinary Publication Date, and (y) shall give notice to the Holders on or prior to the Trigger Breach Determination Date in accordance with Condition 12 (Notices), which notice shall state that no Contingent
Write-down shall occur in relation to the relevant Ordinary Publication Date.
| | ----- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | Viability Event
| | --- | ---------------



| | (i) | Upon the occurrence of a Viability Event, (A) the Issuer shall give notice to the Holders in accordance with Condition 12 (Notices) within
three days of the date on which such Viability Event occurred, which notice shall (x) state that a Viability Event has occurred and a Contingent Write-down will take place and
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



44



---

| | (y) specify the date on which the Contingent Write-down will take place, which date shall be no later than 10 Business Days after the date of such notice (such specified date, the
Viability Event Write-down Date, and such notice, a Viability Event Write-down Notice), and (B) a Contingent Write-down shall occur on the Viability Event Write-down Date in accordance with clause
(d) of this Condition 6.
| | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | A Viability Event shall be deemed to have occurred if:
| | ---- | --------------------------------------------------------



| | (A) | the FINMA has notified UBS AG in writing that it has determined a write-down of the Notes, together with the conversion or write down, as applicable, of holders claims in respect of any other capital instruments
issued by any member of the Group that, pursuant to their terms or by operation of law, are capable of being converted into equity or written down at that time, is, because customary measures to improve UBS AGs capital adequacy are at the time
inadequate or infeasible, an essential requirement to prevent UBS AG from becoming insolvent, bankrupt, unable to pay a material part of its debts as they fall due or unable to carry on its business; or
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (B) | customary measures to improve UBS AGs capital adequacy being at the time inadequate or infeasible, UBS AG has received an irrevocable commitment of direct or indirect extraordinary support from the Public Sector
(beyond customary transactions and arrangements in the ordinary course) that has, or imminently will have, the effect of improving UBS AGs capital adequacy and without which, in the determination of (and as notified in writing by) the FINMA,
UBS AG would have become insolvent, bankrupt, unable to pay a material part of its debts as they fall due or unable to carry on its business.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

whether any of the conditions to the issuance of a Trigger Event Write-down Notice have been met.



| | (d) | Contingent Write-down

If the Issuer has given a Write-down Notice in accordance with
this Condition 6, then on the relevant Write-down Date,

accordingly;
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | the Holders shall be automatically deemed to irrevocably waive their right to receive, and no longer have any rights against the Issuer with respect to, repayment of the aggregate principal amount of the Notes written
down pursuant to clause (i) above (bedingter Forderungsverzicht);
| | ---- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | the Issuer shall pay (A) any accrued and unpaid interest on the Notes and (B) any Additional Amounts related to any interest on the Notes, in the case of each of subclauses (A) and (B) of this clause
(iii), if and only to the extent that such interest or Additional Amount, as applicable, became due and payable to the Holders prior to the relevant Write-down Notice Date; and
| | ----- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iv) | except as described in clause (iii) above, all rights of any Holder for payment of any amounts under or in respect of the Notes (including, without limitation, any amounts arising as a result of, or due and payable
upon the occurrence of, an Event of Default) shall become null and void, irrespective of whether such amounts have become due and payable prior to the relevant Write-down Notice Date or the Write-down Date.
| | ---- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (e) | Determination of CET1 Ratio and Trigger CET1 Ratio
| | --- | --------------------------------------------------

With respect to any Publication
Date, (i) the CET1 Ratio as of the relevant Balance Sheet Date, (ii) the Trigger CET1 Ratio as of such Publication Date and (iii) the components of both of the foregoing, in each case, as published on such Publication Date, shall be
final for purposes of this Condition 6, and any revisions, restatements or adjustments to any of the calculations described in subclauses (i) through (iii) of this clause (e) subsequently published shall have no effect for purposes of
this Condition 6.



|7. | PAYMENTS
|-- | --------



| | (a) | If the Scheduled Due Date for any payment under the Notes does not fall on a Business Day, the Issuer undertakes to effect payment for value on the Business Day immediately following such Scheduled Due Date, and the
Holders shall not be entitled to any additional sum in relation to such payment. All payments required to be made under the Notes (including any Additional Amounts) shall be made to the Holders in U.S dollars without collection costs, without any
restrictions and whatever the circumstances may be, irrespective of nationality, domicile or residence of the relevant Holder and without certification, affidavit or the fulfilment of any other formality.

| | (b) | The Issuer reserves the right to appoint or, after any such appointment, to terminate the appointment of, one or more paying agents to carry out any payment, calculation or other functions in respect of the Notes (each,
a Paying Agent). Any such appointment or termination of appointment shall only take effect not more than 45 and not less than 30 days after the Issuer has notified the Holders of such appointment or termination pursuant to
Condition 12 (Notices); provided, however, that, in the case of insolvency of any Paying Agent, any termination of such Paying Agent and appointment of any other Paying Agent shall take immediate effect. Notwithstanding the
foregoing, if legislation is enacted in Switzerland providing for the taxation of payments according to principles similar to those laid down in the draft legislation proposed by the Swiss Federal Council on 24 August 2011, the Issuer shall
appoint a Paying Agent outside of Switzerland if and to the extent that making such payments through such Paying Agent would eliminate any withholding tax that would otherwise apply to such payments pursuant to such legislation.

| | ----- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iv) | with respect to any Tax collected pursuant to the provisions of, or any laws or an agreement with any Tax Jurisdiction relating to, Sections 1471 through 1474 of the U.S. Internal Revenue Code (commonly referred to as

The Issuer may from time to time without the consent of the Holders
issue further notes and, providedthat such notes have the same terms and conditions as the Notes in all respects (or in all respects except for the issue date and/or first date on which interest is paid), such further notes shall be
consolidated and form a single series with the Notes. If the Issuer issues any such further notes pursuant to this Condition 14, references in these Terms and Conditions to Notes shall include such further notes, unless the

Issuer to the extent of the amount in U.S dollars that such Holder is able to purchase with the amount so received or recovered in such other currency on the date of such receipt or recovery (or, if it is not practicable to purchase U.S dollars with

obligation from the Issuers other obligations hereunder, (ii) give rise to a separate and independent cause of action, (iii) apply irrespective of any indulgence granted by any Holder and (iv) continue in full force and effect
despite any other judgment, order, claim or proof for a liquidated amount in respect of any amount due under the Notes or any other judgment or order.

connection with, the Notes.
