Such cost will equal (i) the lowest amount that a Qualified Financial Institution would charge to effect such assumption (or undertaking), plus (ii) the reasonable expenses (including reasonable attorneys’ fees) incurred by the Holder of this Security in preparing any documentation necessary for such assumption (or undertaking). During the Default Quotation Period, each Holder of this Security and the Company may request a

Qualified Financial Institution to provide a quotation of the amount it would charge to effect such assumption (or undertaking) and notify the other in writing of such quotation. If the Company or any Holder obtains a quotation, it must notify the other party in writing of the quotation. The amount referred to in clause (i) of this paragraph will equal the lowest (or, if there is only one, the only) quotation so obtained, and as to which notice is so given, during the Default Quotation Period; provided that, with respect to any quotation, the party not obtaining such quotation may object, on reasonable and significant grounds, to the effectuation of such assumption (or undertaking) by the Qualified Financial Institution providing such quotation and notify the other party in writing of such grounds within two Business Days after the last day of the Default Quotation Period, in which case such quotation will be disregarded in determining the Default Amount.

The “Default Quotation Period” shall be the period beginning on the day the Default Amount first becomes due and payable and ending on the third Business Day after such due date, unless no such quotation is obtained, or unless every such quotation so obtained is objected to within five Business Days after such due date as provided above, in which case the Default Quotation Period will continue until the third Business Day after the first Business Day on which prompt notice of a quotation is given as provided above, unless such quotation is objected to as provided above within five Business Days after such first Business Day, in which case, the Default Quotation Period will continue as provided in this sentence. Notwithstanding the foregoing, if the Default Quotation Period (and the subsequent two Business Day objection period) has not ended prior to the Final Valuation Date, then the Default Amount will equal the Principal Amount.

The “Final Valuation Date” will be the Trading Day that falls on September 3, 2041, subject to adjustment as provided in Section 3 hereof. If the Final Valuation Date is not a Trading Day, then such Final Valuation Date will be the next succeeding Trading Day, but such delay will not exceed three Trading Days.

1. Promise to Pay at Maturity, Upon Early Redemption, Upon Exercise of Call Right or Upon Acceleration

UBS AG, a corporation duly organized and existing under the laws of Switzerland (herein called the “Company,” which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay (or cause to be paid) to Cede & Co., as nominee for The Depository Trust Company, or registered assigns, the principal sum, calculated as provided under (i) “Early Redemption” and elsewhere on the face of this Security on the applicable Redemption Date, in the case of any Securities in respect of which a Holder exercises such Holder’s right to require the Company to redeem such Holder’s Securities prior to the Maturity Date, (ii) “Call Right” and elsewhere on the face of this Security on the Call Settlement Date, in the case of Securities subject to the Company’s exercise of its Call Right, (iii) “Acceleration upon Minimum Indicative Value” and elsewhere on the face of this Security on the Acceleration Settlement Date, in the case of Securities subject to acceleration upon minimum indicative value, or (iv) “Payment at Maturity” and elsewhere on the face of this Security on the Maturity Date, in the case of all other Securities.

If the Index Sponsor discontinues publication of or otherwise fails to publish the Index, and another entity publishes an index that the Calculation Agent determines to be comparable to the discontinued Index and the Calculation Agent approves such index as a Successor Index, then the Calculation Agent will determine the value of the Index on the applicable Valuation Date and the amount payable at maturity or call, upon acceleration or upon early redemption by reference to such Successor Index.

Upon any selection by the Calculation Agent of a Successor Index, the Calculation Agent will cause written notice thereof to be furnished to the trustee, to the Company and to the Holders of the Securities.

If the Calculation Agent determines that the publication of the Index is discontinued and there is no Successor Index, or that a Market Disruption Event or force majeure event has occurred and is continuing on the date on which the value of the Index is required to be determined, the Calculation Agent will determine the amount payable by a computation methodology that the Calculation Agent determines will as closely as reasonably possible replicate the Index.

If the Calculation Agent determines that the Index or the method of calculating the Index has been changed at any time in any respect, including whether the change is made by the Index Sponsor under its existing policies or following a modification of those policies, is due to the publication of a Successor Index, or is due to any other reason, then the Calculation Agent will be permitted (but not required) to make such adjustments to the Index

or method of calculating the Index as it believes are appropriate to ensure that the value of the Index used to determine the amount payable at maturity, call, acceleration or upon early redemption is equitable.

If the Index is not published on a Trading Day, or if a Market Disruption Event or a force majeure event has occurred or is occurring, and such event affects that Index, any futures contract underlying the Index and/or the ability of the Company to hedge the Index, the Calculation Agent may (but is not required to) make determinations and/or adjustments to the Index or method of calculating the Index. The determination of the value of this Security on a Valuation Date, including the Final Valuation Date, may be postponed if the Calculation Agent determines that a Market Disruption Event or force majeure event has occurred or is continuing on such Valuation Date. In that event, the applicable Valuation Date will be the next following Trading Day on which a Market Disruption Event or force majeure event does not occur and is not continuing. In no event, however, will a Valuation Date be postponed by more than three Trading Days. If a Valuation Date is postponed until the third Trading Day following the scheduled Valuation Date but a Market Disruption Event or force majeure event occurs or is continuing on such day, that day will nevertheless be the Valuation Date and the Calculation Agent will make a good faith estimate in its sole discretion of the value of the Index for such day. All determinations and adjustments to be made by the Calculation Agent may be made in the Calculation Agent’s sole discretion.

If the Calculation Agent determines that a Market Disruption Event or force majeure event occurs or is continuing on September 3, 2041, then the Final Valuation Date will be the first following Trading Day on which the Calculation Agent determines that a Market Disruption Event or force majeure event does not occur and is not continuing. In no event will the Final Valuation Date be posptoned by more than three Trading Days. If the third Trading Day before September 3, 2041 does not qualify as the Final Valuation Date because the Calculation Agent has determined that a Market Disruption Event or force majeure event has occurred or is continuing, then the Maturity Date will be the third Trading Day following the Final Valuation Date.

4. Payment at Maturity, Upon Early Redemption, on the Call Settlement Date or on the Acceleration Settlement Date

The payment of this Security that becomes due and payable on the Maturity Date, a Redemption Date, the Acceleration Date or the Call Settlement Date, as the case may be, shall be the cash amount that must be paid to redeem this Security as provided herein under “Payment at Maturity,” “Early Redemption,” “Acceleration upon Minimum Indicative Value” and “Call Right,” respectively. The payment of this Security that becomes due and payable upon acceleration of the Maturity Date hereof after an Event of Default has occurred pursuant to the Indenture shall be the Default Amount. When the principal referred to in either of the two preceding sentences has been paid as provided herein (or such payment has been made available), the principal of this Security shall be deemed to have been paid in full, whether or not this Security shall have been surrendered for payment or cancellation. References to the payment at maturity, acceleration or upon early redemption or call of this Security on any day shall be deemed to mean the payment of cash that is payable on such day as provided in this Security. This Security shall cease to be Outstanding as provided in the

definition of such term in the Indenture when the principal of this Security shall be deemed to have been paid in full as provided above.

Subject to the minimum redemption amount provided under “Early Redemption,” the Holder may require the Company to redeem the Holder’s Securities during the term of the Securities on any Redemption Date on or after September 19, 2011 to and including August 30, 2041, provided that such Holder instructs its broker or other person through whom the Securities are held to (i) deliver a redemption notice to the Company via email no later than 12:00 noon (New York City time) on the Trading Day immediately preceding the applicable Valuation Date; (ii) deliver the signed redemption confirmation to the Company via facsimile in the specified form by 5:00 p.m. (New York City time) on the same day; (iii) instruct the Holder’s DTC custodian to book a delivery versus payment trade with respect to the Holder’s Securities on the applicable Valuation Date at a price equal to the Redemption Amount; and (iv) cause the Holder’s DTC custodian to deliver the trade as booked for settlement via DTC prior to 10:00 a.m. (New York City time) on the applicable Redemption Date.

The Securities are subject to redemption upon not less than ten (10) calendar days’ prior notice on any Trading Day on or after September 12, 2012 through and including the Maturity Date, as a whole and not in part, at the election of the Company. If the Company elects to redeem the Securities on the Call Settlement Date, the Holder will receive a cash payment equal to the Call Settlement Amount.

The Calculation Agent will be solely responsible for all determinations and calculations regarding the value of the Securities, including at maturity, acceleration or upon early redemption or call, Market Disruption Events, force majeure events, Business Days, Trading Days, the Daily Index Factor, the Tracking Fee, the Redemption Fee and the Current Principal Amount, the payment at maturity, if any, that the Company will pay the Holder at maturity, the Acceleration Amount, if any, that the Company will pay the Holder on the Acceleration Settlement Date, the Redemption Fee, if any, that the Company will pay the Holder upon redemption, if applicable, the Call Settlement Amount, if any, that the Company will pay the Holder in the event that the Company calls the Securities and all such other matters as may be specified elsewhere herein as matters to be determined by the Calculation Agent. The Calculation Agent shall make all such determinations and calculations in its sole discretion, and absent manifest error, all determinations of the Calculation Agent shall be final and binding on the Company, the Holder and all other Persons having an interest in this Security, without liability on the part of the Calculation Agent. The Holder of this Security shall not be entitled to any compensation from the Company for any loss suffered as a result of any determinations or calculations made by the Calculation Agent.

The Company shall take such action as shall be necessary to ensure that there is, at all relevant times, a financial institution serving as the Calculation Agent hereunder.

The Company may, in its sole discretion at any time and from time to time, upon written notice to the Trustee, but without notice to the Holder of this Security, terminate the appointment of any Person serving as the Calculation Agent and appoint another Person (including any Affiliate of the Company) to serve as the Calculation Agent. Insofar as this Security provides for the Calculation Agent to determine Market Disruption Events, force majeure events, Business Days, Trading Days, the Daily Index Factor, the Tracking Fee, the Redemption Fee and the Current Principal Amount, the payment at maturity, if any, that the Company will pay the Holder at maturity, the Acceleration Amount, if any, that the Company will pay the Holder on the Acceleration Settlement Date, and all such other matters as may be specified elsewhere herein as matters to be determined by the Calculation Agent on any date or other information from any institution or other source, the Calculation Agent may do so from any source or sources of the kind contemplated or otherwise permitted hereby notwithstanding that any one or more of such sources are the Calculation Agent, affiliates of the Calculation Agent or affiliates of the Company.

By its purchase of this Security, the Holder, on behalf of itself and any other Person having a beneficial interest in this Security, hereby agrees with the Company (in the absence of a statutory, regulatory, administrative or judicial ruling to the contrary) to treat this Security for all U.S. federal income tax purposes as a pre-paid derivative contract with respect to the Index.

If the Current Principal Amount on any Business Day is above $400.00, the Company may, but shall not be required to, initiate a 4-for-1 split of the Securities. If the Current Principal Amount on any Business Day is below $100.00, the Company may, but shall not be required to, initiate a 1-for-4 reverse split of the Securities.

If the Securities are split, the terms of the Securities (including without limitation the Current Principal Amount) will be adjusted accordingly as described below. If the Securities undergo a 4-for-1 split, each Holder of a Security on the relevant record date will, after the split, hold four Securities. The record date for any split shall be the 9th Business Day after the day on which the Company’s right to initiate a split was triggered by the Current Principal Amount being above $400.00. The Current Principal Amount on such record date would be divided by four to reflect the 4-for-1 split of the Securities. Any adjustment of the Current Principal Amount will be rounded to eight decimal places. Settlement of any split shall be on a standard T+3 basis.

In the case of a reverse split, the Company may address odd numbers of Securities in a manner determined by it in its sole discretion. If the Securities undergo a 1-for-4 reverse split, each Holder who holds four Securities on the relevant record date will, after the reverse split, hold only one Security and adjustments will be made as described below. The record date for any reverse split shall be the 9th Business Day after the day on

which the Company’s right to initiate a reverse split was triggered by the Current Principal Amount being below $100.00. The Current Principal Amount on such record date would be multiplied by four to reflect the 1-for-4 reverse split of the Securities. Any adjustment of the Current Principal Amount will be rounded to eight decimal places. Settlement of any split shall be on a standard T+3 basis.

In the case of a reverse split, Holders who own a number of Securities on the record date which is not evenly divisible by four will receive the same treatment as all other Holders for the maximum number of Securities they hold which is evenly divisible by four, and the Company will have the right to compensate Holders for their remaining or “partial” Securities in a manner determined by it in its sole discretion.

Payment of any amount payable on this Security will be made in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. Payment will be made to an account designated by the Holder (in writing to the Company and the Trustee on or before the applicable Valuation Date or Final Valuation Date) and acceptable to the Company or, if no such account is designated and acceptable as aforesaid, at the office or agency of the Company maintained for that purpose in The City of New York, provided, however, that payment on the Maturity Date, Call Settlement Date, Acceleration Settlement Date or any Redemption Date shall be made only upon surrender of this Security at such office or agency (unless the Company waives surrender). Notwithstanding the foregoing, if this Security is a Global Security, any payment may be made pursuant to the Applicable Procedures of the Depositary as permitted in said Indenture.

All dollar amounts related to the determination of the Current Principal Amount, the Redemption Amount, the Redemption Fee, the Tracking Fee, the Call Settlement Amount and the Acceleration Amount per Security, if any, will be rounded to the nearest ten-thousandth, with five one hundred-thousandths rounded upward (e.g., .76545 would be rounded up to .7655); and all dollar amounts paid on the aggregate principal amount of Securities per Holder will be rounded to the nearest cent, with one-half cent rounded upward.

Reference is hereby made to the further provisions of this Security set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place.

Unless the certificate of authentication hereon has been executed by the Trustee referred to on the reverse hereof by manual signature, this Security shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

This is one of the Securities of the series designated herein and referred to in the Indenture.

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”) issued and to be issued in one or more series under the Indenture, dated as of November 21, 2000, as amended and supplemented by the First Supplemental Indenture, dated as of February 28, 2006 (herein called the “Indenture,” which term shall have the meaning assigned to it in such instrument), between the Company and U.S. Bank Trust National Association, as Trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee, the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. Insofar as the provisions of the Indenture may conflict with the provisions set forth on the face of this Security, the latter shall control for purposes of this Security.

This Security is one of the series designated on the face hereof, limited to an aggregate initial offering price not to exceed $100,000,000 (or the equivalent thereof in any other currency or currencies or currency units), which amount may be increased at the option of the Company if in the future it determines that it may wish to sell additional Securities of this series. References herein to “this series” mean the series designated on the face hereof.

Payments under the Securities will be made without withholding or deduction for or on account of any present or future tax, duty, assessment or governmental charge (“Taxes”) imposed upon or as a result of such payments by Switzerland or any jurisdiction in which a branch of the Company through which the Securities are issued is located (or any political subdivision or taxing authority thereof or therein) (a “Relevant Jurisdiction”), 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 in Section 1007 of the Indenture, 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 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.

In addition to its ability to redeem this Security pursuant to the foregoing, if at any time as a result of any change in or amendment to the laws or regulations of a Relevant Jurisdiction affecting taxation, or a change in any application or interpretation of such laws or regulations (including the decision of any court or tribunal) either generally or in relation to any particular Securities, which change, amendment, application or interpretation becomes effective on or after the Initial Trade Date in making any payment of, or in respect of, the principal amount of the Securities, the Company would be required to pay any Additional Amounts with respect thereto, then the Securities will be redeemable upon not less than ten nor more

than sixty days’ notice by mail, at any time thereafter, in whole but not in part, at the election of the Company as provided in the Indenture at a redemption price determined by the Calculation Agent in a manner reasonably calculated to preserve the relative economic position of the Company and the Holders of Outstanding Securities.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of all series to be affected (considered together as one class for this purpose). The Indenture also contains provisions (i) permitting the Holders of a majority in principal amount of the Securities at the time Outstanding of all series to be affected under the Indenture (considered together as one class for this purpose), on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and (ii) permitting the Holders of a majority in principal amount of the Securities at the time Outstanding of any series to be affected under the Indenture (with each such series considered separately for this purpose), on behalf of the Holders of all Securities of such series, to waive certain past defaults under the Indenture and their consequences. 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 indemnity reasonably satisfactory to it, 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 sixty 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 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 this Security as herein provided.

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 this Security is 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. 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.

This Security, and any other Securities of this series and of like tenor, are issuable only in registered form without coupons in denominations of any multiple of $100.00. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

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.

This Security is a Global Security and is subject to the provisions of the Indenture relating to Global Securities, including the limitations in Section 305 thereof on transfers and exchanges of Global Securities.

This Security and the Indenture shall be governed by and construed in accordance with the laws of the State of New York.

All terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture.
