(c) Actions Against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability that it may have otherwise than on account of this indemnity agreement.

If an indemnifying party assumes the defense of such action, the indemnifying party shall not be liable for any fees and expenses of counsel for the indemnified parties incurred thereafter in connection with such action. An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying party be liable for fees and expenses of more than one counsel (in addition to any one firm of local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the -23- same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party. (d) Settlement Without Consent If Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for reasonable fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

In order to provide for just and equitable contribution in circumstances under which the indemnification provided for in Section 6 hereof is for any reason held to be unenforceable by an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the UBS Entities on the one hand and the Underwriters on the other hand from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the UBS Entities on the one hand and of the Underwriters on the other hand in connection with the statements or omissions that resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations. The relative benefits received by the UBS Entities on the one hand and the Underwriters on the other hand in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses but after deducting the total underwriting commission received by the -24- Underwriters) received by the UBS Entities and the total underwriting commission received by the Underwriters, in each case as set forth on the cover of the Prospectus, bear to the aggregate initial public offering price of the Securities as set forth on such cover. The relative fault of the UBS Entities on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the UBS Entities or by the Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The UBS Entities and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to above in this Section 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission. Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Trust Preferred Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 7, each person, if any, who controls an Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act shall have the same rights to contribution as such Underwriter, and each director or Supervisory or Managing Board member or the equivalent of the UBS Entities, the Trustee, each officer of the UBS Entities who signed the Registration Statement, and each person, if any, who controls any of the UBS Entities within the meaning of Section 15 of the Act or Section 20 of the Exchange Act shall have the same rights to contribution as the UBS Entities. The Underwriters' respective obligations to contribute pursuant to this Section 7 are several in proportion to the number of Trust Preferred Securities set forth opposite their respective names in Schedule A hereto and not joint. -25- SECTION 8. Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements contained in this Agreement or in certificates of officers of the UBS Entities or any of their subsidiaries submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or controlling person, or by or on behalf of the UBS Entities, and shall survive delivery of the Trust Preferred Securities to the Underwriters. SECTION 9. Termination of Agreement. (a) Termination; General. The Representative may terminate this Agreement, by notice to the Guarantor, at any time at or prior to the time of purchase if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Registration Statement, Pre-Pricing Prospectus, Permitted Free Writing Prospectus, if any, and the Prospectus, any material adverse change in the condition, financial or otherwise, or in the earnings or business affairs or business prospects of the UBS Entities and their subsidiaries, considered as one enterprise, whether or not arising in the ordinary course of business, or (i) if there has occurred any material adverse change in the international financial markets or the financial markets in the United States or Switzerland, or any outbreak of hostilities or escalation thereof affecting the United States or Switzerland or other calamity or crisis, or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Representative (after discussion with the Guarantor to the extent practicable), impracticable to market the Trust Preferred Securities or to enforce contracts for the sale of the Trust Preferred Securities, or (ii) if trading in any securities of the UBS Entities has been suspended or materially limited by the Commission, the New York Stock Exchange or [insert applicable stock exchanges] or (iii) if trading generally on the American Stock Exchange or the New York Stock Exchange or the [insert applicable stock exchanges] or in the Nasdaq National Market has been suspended or limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any such exchanges or by such system or by order of the Commission, the National Association of Securities Dealers, Inc. or any other governmental authority, or (iv) if trading in any securities of the Guarantor has been suspended or limited on any stock exchange in Switzerland, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required by any such stock exchange or any competent governmental authority in or of Switzerland, or (v) if a banking moratorium has been declared by either Federal or New York, or Swiss authorities, or (vi) if there has occurred a change or an official announcement by a competent authority of a forthcoming change in Swiss taxation materially adversely affecting the Guarantor or the Guarantee or the transfer thereof or the imposition of exchange controls by the United States or Switzerland. (b) Liabilities. If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in -26- Section 4 hereof, and provided further that Sections 1, 6, 7 and 8 shall survive such termination and remain in full force and effect. SECTION 10. Default by One or More of the Underwriters. If one or more of the Underwriters shall fail at the time of purchase to purchase the Trust Preferred Securities that it or they are obligated to purchase under this Agreement (the "Defaulted Securities"), the Representative shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representative shall not have completed such arrangements within such 24-hour period, then: (i) if the number of Defaulted Securities does not exceed 10% of the aggregate number of the Trust Preferred Securities to be purchased hereunder, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters, or (ii) if the number of Defaulted Securities exceeds 10% of the aggregate number of the Trust Preferred Securities to be purchased hereunder, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter. No action taken pursuant to this Section shall relieve any defaulting Underwriter from liability in respect of its default. In the event of any such default that does not result in a termination of this Agreement, either the Representative or the Guarantor shall have the right to postpone the time of purchase for a period not exceeding seven days in order to effect any required changes in the Registration Statement or Prospectus or in any other documents or arrangements. As used herein, the term "Underwriter" includes any person substituted for an Underwriter under this Section 10. SECTION 11. Notices. All notices, requests, statements and other communications hereunder shall be in writing and shall be delivered or sent by mail, messenger or any standard form of telecommunication. Notices to the Underwriters shall be directed to the Representative c/o UBS Securities LLC, Attention: Debt Syndicate Manager, Facsimile No. [(203) 719-0495]; and notices to the Guarantor shall be directed to UBS AG, Attention: General Counsel, Facsimile No. [212) 821-5804]. Any such notice, request, statement or communication shall be effective upon receipt thereof. -27- SECTION 12. Parties. This Agreement shall inure to the benefit of and be binding upon the Underwriters and the UBS Entities and their respective successors. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Underwriters and the UBS Entities and their respective successors and the controlling persons and officers and directors and Supervisory and Managing Board members or the equivalent referred to in Sections 6 and 7, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the Underwriters and the UBS Entities and their respective successors, and said controlling persons and officers and directors and Supervisory and Managing Board members or the equivalent, and for the benefit of no other person, firm or corporation. No purchaser of Trust Preferred Securities from any Underwriter shall be deemed to be a successor by reason merely of such purchase. SECTION 13. Governing Law, Submission for Jurisdiction. (a) Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. EXCEPT AS OTHERWISE SET FORTH HEREIN, SPECIFIED TIMES OF DAY REFER TO NEW YORK CITY TIME. (b) Submission to Jurisdiction. Each of the parties hereto irrevocably (i) agrees that any legal suit, action or proceeding against the UBS Entities brought by any Underwriter or by any person who controls any Underwriter arising out of or based upon this Agreement or the transactions contemplated hereby may be instituted in any Federal court located in the State of New York, (ii) waives, to the fullest extent it may effectively do so, any objection that it may now or hereafter have to the laying of venue of any such proceeding and (iii) submits to the non-exclusive jurisdiction of such courts in any such suit, action or proceeding. The Guarantor irrevocably waives any immunity to jurisdiction to which it may otherwise be entitled or become entitled (including sovereign immunity, immunity to pre-judgment attachment, post-judgment attachment and execution) in any legal suit, action or proceeding against it arising out of or based on this Agreement or the transactions contemplated hereby that is instituted in any New York court or in any competent court in Switzerland.

Judgment Currency. In respect of any judgment or order given or made for any amount due hereunder that is expressed and paid in a currency (the "judgment currency") other than United States dollars, the Guarantor will indemnify each Underwriter against any loss incurred by such Underwriter as a result of any variation as between (i) the rate of exchange at which the United States dollar amount is converted into the judgment currency for the purpose of such judgment or order and (ii) the rate of exchange at which an Underwriter is able to purchase United States dollars with the amount of the judgment currency actually received by such Underwriter. The foregoing indemnity shall constitute a separate and independent obligation of the Guarantor and shall continue in full force and effect notwithstanding any such judgment or order as aforesaid. The term "rate of exchange" shall include any premiums and costs of exchange payable in connection with the purchase of or conversion into United States dollars. In the event that any such Underwriter, as a result of any variation as noted in (i) or (ii) above, recovers an amount of United States dollars on conversion of a sum paid in a judgment currency, which amount is in excess of the judgment or order given or made in United States dollars, such Underwriter shall remit such excess to the Guarantor.

The statements in the Prospectus under the captions "The UBS Preferred Funding Trusts", "The UBS Preferred Funding Companies", "Description of Trust Preferred Securities", "Description of Company Preferred Securities", "Description of UBS AG Subordinated Guarantees" and "Description of Subordinated Notes of UBS AG" and the statements in the Prospectus Supplement under the captions "Summary", "Supplemental Information Regarding UBS Preferred Funding Trust ___ ", "Supplemental Information Regarding UBS Preferred Funding Company LLC ___ ", "Description of Trust Preferred Securities", "Description of Company Preferred Securities", and "Description of Subordinated Notes of UBS AG", insofar as such statements purport to constitute a summary of the terms of any of the Transaction Documents, constitute accurate summaries thereof in all material respects. 5.
