(a) Payments under the Securities will be made without deduction or withholding for or on account of any present or future tax, duty, assessment or governmental charge imposed upon or as a result of such payments by a Relevant Jurisdiction (“Taxes”), unless required by law. To the extent any such Taxes are so levied or imposed, the Company will, subject to the exceptions and limitations set forth below, pay such additional amounts (“Additional Amounts”) to the Holder of any Security who is not a resident of the Relevant Jurisdiction as may be necessary in order that every net payment of the principal of and interest on such Security and any other amounts payable on such Security, after withholding for or on account of such Taxes imposed upon or as a result of such payment, will not be less than the amount provided for in such Security to be then due and payable.

(b) Notwithstanding the provisions of Section 2.04(a), the Company will not be required to make any payment of Additional Amounts in relation to any Security:

(1) to a Holder who is liable to such Taxes on that Security as a result of having some connection with the Relevant Jurisdiction other than its mere ownership or possession of the Security or the receipt of principal or interest in respect thereof;

(2) that is presented for payment more than 30 days after the Relevant Date except to the extent that the Holder would have been entitled to receive the Additional Amounts if it had presented the Security for payment on the last day of the 30-day period;

(3) where such withholding or deduction is imposed on a payment and is required to be made pursuant to laws enacted by 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 April 3, 2020, or otherwise changing the Swiss federal withholding tax system from an issuer-based system to a paying-agent-based system pursuant to which a Person other than the Company is required to withhold tax on any interest payments;

(4) on account of any such Taxes which would not have been so imposed but for the existence of any present or former connection between such Holder (or between a fiduciary, settler, beneficiary, member or shareholder of such Holder, if such Holder is an estate, a trust, a partnership or a corporation) and the United States including, without limitation, such Holder (or such fiduciary, settler, beneficiary, member or shareholder) being or having been a citizen or resident thereof or being or having been engaged in a trade or business or present therein or having, or having had, a permanent establishment therein;

(5) on account of any estate, inheritance, gift, sales, transfer or personal property tax or any similar tax, duty, assessment or governmental charge;

(6) on account of any Taxes which are payable otherwise than by withholding or deduction from payments on or in respect of any Security;

(7) on account of any Taxes which would not have been imposed but for the failure of a Holder, or any intermediary, custodian or broker, to comply with certification, information or other reporting requirements concerning the nationality, residence or identity of the holder or beneficial owner of such Security, if such compliance is required by statute or by regulation of or on behalf of the United States as a precondition to relief or exemption from such tax, assessment or other governmental charge;

(8) on account of any Taxes imposed solely because the Holder is a bank purchasing the Security in the ordinary course of its lending business;

(9) on account of any Taxes required to be deducted or withheld by any paying agent from a payment on the Security if such payment can be made without such deduction or withholding by a paying agent other than the one required to make such a deduction or withholding;

(10) on account of any Taxes imposed on (A) a Holder that actually or constructively owns 10% or more of the combined voting power of all classes of stock of the Company entitled to vote; or (B) contingent interest as described in section 871(h)(4) of the Code; or

nor shall Additional Amounts be paid with respect to any payment on a Security to a Holder who is a fiduciary or partnership or other than the sole beneficial owner of such payment to the extent such payment would be required to be included in the income, for tax purposes, of a beneficiary or settlor with respect to such fiduciary or a member of such partnership or a beneficial owner who would not have been entitled to the Additional Amounts had such beneficiary, settlor, member or beneficial owner been the Holder of the Security.

“Relevant Date” means the date on which the payment first becomes due. If the full amount of the moneys payable on the due date has not been received by the Trustee on or before the due date, then “Relevant Date” means the date on which notice to the effect that the full amount of the money due has been received by the Trustee is given to Holders.

Notwithstanding any other provisions contained herein, the Company shall be permitted to withhold or deduct any amounts required by the rules of Section 871(m) of the U.S. Internal Revenue Code of 1986, as amended (the “Code”) or any amended or successor provisions (relating to withholding or dividend equivalents) or Sections 1471 through 1474 of the Code, or any amended or successor provisions, pursuant to any inter-governmental agreement or implementing legislation adopted by another jurisdiction in connection with these provisions, or pursuant to any agreement with the U.S. Internal Revenue Service (“FATCA withholding”) as a result of a holder, beneficial owner or an intermediary not being entitled to receive payments free of FATCA withholding. The Company will have no obligation to pay additional amounts or otherwise indemnify an investor for any such withholding deducted or withheld by the Company, the Paying Agent, the Trustee, or any other party.

(c) The provisions of this Section 2.04 shall also apply to any Taxes imposed by (i) any jurisdiction in which a Person into which the Company has merged or to which the Company has

conveyed, transferred or leased its property is a resident for tax purposes, and (ii) after giving effect to any Issuing Branch Substitution (unless Company is acting through UBS Head Office immediately after giving effect to such Issuing Branch Substitution), the jurisdiction of establishment of the Branch through which the Company is acting immediately after giving effect to such Issuing Branch Substitution, and, in each case, such jurisdiction shall thereafter be treated in the same manner as a Relevant Jurisdiction for purposes of this Section 2.04.

(d) For purposes of this Section 2.04, any references to principal of and/or interest on the Securities shall be deemed to include a reference to any relevant premium and/or Additional Amounts payable in respect of such Securities.

(a) The Company shall not consolidate with or merge into any other Person or convey, transfer or lease its properties and assets substantially as an entirety to any Person, and the Company shall not permit any Person to consolidate with or merge into the Company or convey, transfer or lease its properties and assets substantially as an entirety to the Company, unless:

(2) immediately after giving effect to such transaction and treating any indebtedness which becomes an obligation of the Company or any Subsidiary as a result of such transaction as having been incurred by the Company or such Subsidiary at the time of such transaction, no Event of Default, and no event which, after notice or lapse of time or both, would become an Event of Default, shall have happened and be continuing;

(3) if, as a result of any such consolidation or merger or such conveyance, transfer or lease, properties or assets of the Company would become subject to a mortgage, pledge, lien, security interest or other encumbrance which would not be permitted by the Indenture, the Company or such successor Person, as the case may be, shall take such steps as shall be necessary effectively to secure the Securities equally and ratably with (or prior to) all indebtedness secured thereby; and

Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount of the Securities of this series at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee shall not have received from the Holders of a majority in principal amount of Securities of this series at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of and any premium and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.
