If such corporation publishes reports of condition at least annually, pursuant to law or to the requirements of the supervising or examining authority referred to above, then, for the purposes of this Section 3.01(a)(ii), the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. (b) If at any time the Guarantee Trustee shall cease to be eligible to so act under Section 3.01(a), the Guarantee Trustee shall immediately resign in the manner and with the effect set out in Section 3.02(c). (c) If the Guarantee Trustee has or shall acquire any "conflicting interest" within the meaning of Section 310(b) of the Trust Indenture Act, the Guarantee Trustee and Guarantor shall in all respects comply with the provisions of Section 310(b) of the Trust Indenture Act.

The Guarantee Trustee may resign from office (without need for prior or subsequent accounting) by an instrument in writing executed by the Guarantee Trustee and delivered to the Guarantor, which resignation shall not take effect until a Successor Guarantee Trustee has been appointed and has accepted such appointment by instrument in writing executed by such Successor Guarantee Trustee and delivered to the Guarantor and the resigning Guarantee Trustee. (d) If no Successor Guarantee Trustee shall have been appointed and accepted appointment as provided in this Section 3.02 within 60 days after delivery of an instrument of removal or resignation, the Guarantee Trustee resigning or being removed may petition, at the expense of the Guarantor, any court of competent jurisdiction for appointment of a Successor Guarantee Trustee. Such court may thereupon, after -15- prescribing such notice, if any, as it may deem proper, appoint a Successor Guarantee Trustee. (e) No Guarantee Trustee shall be liable for the acts or omissions to act of any Successor Guarantee Trustee. (f) Upon termination of this Guarantee or removal or resignation of the Guarantee Trustee pursuant to this Section 3.02, and before the appointment of any Successor Guarantee Trustee, the Guarantor shall pay to the Guarantee Trustee all amounts to which it is entitled to the date of such termination, removal or resignation. ARTICLE IV GUARANTEE Section 4.01. Guarantee. (a) The Guarantor irrevocably and unconditionally agrees with the Guarantee Trustee, the Initial Holder and the Holders from time to time of the Company Preferred Securities, subject to the limitations set forth in this Guarantee, to pay in full to the Initial Holder and each subsequent Holder of Company Preferred Securities, whether such rights under this Guarantee are asserted by the Guarantee Trustee or directly by any such Holder (without duplication of amounts theretofore paid to the Holders of the Company Preferred Securities by the Company), regardless of any defense, right of set-off or counterclaim that the Company may have or assert: (i) on each Mandatory Dividend Payment Date, Dividends on the Company Preferred Securities in an amount equal to the Mandatory Dividend Payment Amount; (ii) on each other Dividend Payment Date, Dividends (if any) on the Company Preferred Securities that have become Definitive Dividends as to such Dividend Payment Date because the Guarantor did not deliver a No Dividend Instruction (as defined in the LLC Agreement); (iii) on each Redemption Date, the Redemption Price payable with respect to the Company Preferred Securities called for redemption by the Company; (iv) upon any voluntary or involuntary dissolution, liquidation or winding up of the Company, the Liquidation Distribution; and (v) any Additional Amounts payable by the Company with respect to the payment set forth in clauses (i) through (iv), above, under the LLC Agreement; -16- (collectively, the "Guarantee Payments"); provided that, if a Bankruptcy Event has occurred as to the Guarantor, the Guarantee Payments payable under clause (i), (ii), (iii) and (iv) above of this Section 4.01 shall be an amount equal to the lesser of (A) the aggregate amount of Guarantee Payments pursuant to such clause of this Section 4.01 without giving effect to this proviso and (B) an amount calculated as (1) the remaining assets of the Guarantor in the related bankruptcy or insolvency proceeding after satisfaction of all claims which, as a matter of law, are prior to those of holders of this Guarantee or any Parity Guarantee multiplied by (2) a fraction, (x) the numerator of which is the aggregate amount of Guarantee Payments pursuant to such clause of this Section 4.01 without giving effect to this proviso and (y) the denominator of which is the aggregate principal or face amount of all claims under this Guarantee and the Parity Guarantees. All Guarantee Payments shall include interest accrued on such Guarantee Payments, at a rate per annum equal to the stated Dividend Rate of the Company Preferred Securities, since the date of the claim asserted under this Guarantee relating to such Guarantee Payments. (b) The Guarantor's obligation to make any of the payments listed in (i) through (iii) of subsection (a) above may be satisfied by direct payment of the required amounts (which shall be in United States dollars) by the Guarantor to the Holders or by causing the Company to pay such amounts to the Holders. Section 4.02. Delivery of Guarantor Certificate. As of each (x) Dividend Payment Date with respect to which the Company has not paid the full amount of Dividends at the Dividend Rate payable as contemplated by clause (i) or (ii), as applicable, of Section 4.01(a) or (y) Redemption Date with respect to which the Company has not paid the Redemption Price in full, the Guarantor shall deliver an Officers' Certificate to the Guarantee Trustee within five Business Days after such Dividend Payment Date or Redemption Date, as applicable, substantially in the form attached as Exhibit A (the "Guarantor Certificate"). Section 4.03. Waiver of Notice and Demand. The Guarantor hereby waives notice of acceptance of this Guarantee and of any liability to which it applies or may apply, presentment, demand for payment, any right to require a proceeding first against the Company or any other Person before proceeding against the Guarantor, protest, notice of nonpayment, notice of dishonor, notice of redemption and all other notices and demands. Section 4.04. Obligations Not Affected. The obligations, covenants, agreements and duties of the Guarantor under this Guarantee shall in no way be affected or impaired by reason of the happening from time to time of any of the following: (a) the release or waiver, by operation of law or otherwise, of the performance or observance by the Company of any express or implied agreement, covenant, term or condition relating to the Company Preferred Securities to be performed or observed by the Company; -17- (b) the extension of time for the payment by the Company of all or any portion of the Dividends, Redemption Price, Liquidation Distribution or any other sums payable under the terms of the Company Preferred Securities or the extension of time for the performance of any other obligation under, arising out of, or in connection with, the Company Preferred Securities; provided that nothing in this Guarantee shall affect or impair any valid extension; (c) any failure, omission, delay or lack of diligence on the part of the Holders of the Company Preferred Securities to enforce, assert or exercise any right, privilege, power or remedy conferred on such Holders pursuant to the terms of the Company Preferred Securities, or any action on the part of the Company granting indulgence or extension of any kind; (d) the voluntary or involuntary liquidation, dissolution, sale of any collateral, receivership, insolvency, bankruptcy, assignment for the benefit of creditors, reorganization, arrangement, composition or readjustment of debt of, or other similar proceedings affecting, the Company or any of the assets of the Company; (e) any invalidity of, or defect or deficiency in, the Company Preferred Securities; (f) the settlement or compromise of any obligation guaranteed hereby or hereby incurred; or (g) any other circumstance whatsoever that might otherwise constitute a legal or equitable discharge or defense of a guarantor, it being the intent of this Section 4.04 that the obligations of the Guarantor hereunder shall be absolute and unconditional under any and all circumstances. There shall be no obligation of the Holders to give notice to, or obtain consent of, the Guarantor with respect to the happening of any of the foregoing. Section 4.05. Action Against Guarantor. The Guarantor waives any right or remedy to require that any action be brought first against the Company or any other person or entity before proceeding directly against the Guarantor. Section 4.06. Independent Obligations. The Guarantor acknowledges that its obligations hereunder are independent of the obligations of the Company with respect to the Company Preferred Securities, and that the Guarantor shall be liable as principal and as debtor hereunder to make Guarantee Payments pursuant to the terms of this Guarantee notwithstanding the occurrence of any event referred to in subsections (a) through (g), inclusive, of Section 4.04. It is further understood that all rights of a Holder of a Company Preferred Security against the Guarantor under this Guarantee, and all corresponding obligations of the Guarantor to such Holder, are separate and independent of the rights and corresponding obligations between the Guarantor and the respective Holders of the other Company Preferred Securities. -18- Section 4.07. Taxes. All payments in respect of the Guarantee Payments (including interest accrued thereon, if any) by the Guarantor shall be made without withholding or deduction for or on account of any Relevant Tax, unless the withholding or deduction of such Relevant Tax is required by law. In that event, the Guarantor shall pay, as further Guarantee Payments, such additional amounts as may be necessary in order that the net amounts received by a Holder (or a third party on its behalf) after such withholding or deduction will equal the amount which would have been received in respect of the Guarantee Payments (including interest accrued thereon, if any) in the absence of such withholding or deduction ("Guarantee Additional Amounts"), except that no such Guarantee Additional Amounts shall be payable to a Holder (or a third party on its behalf) with respect to any Guarantee Payments (including interest accrued thereon, if any), (i) to the extent that such Relevant Tax is imposed or levied by virtue of such Holder (or the beneficial owner of Company Preferred Securities to which such Guarantee Payments relate) (other than the Trust) having some connection with the Relevant Jurisdiction, other than being a Holder of Company Preferred Securities (or beneficial owner of Company Preferred Securities) or (ii) to the extent that such the Relevant Tax is imposed or levied by virtue of such Holder (or beneficial owner) (other than the Trust) not having made a declaration of non-residence in, or other lack of connection with, the Relevant Jurisdiction or any similar claim for exemption, if the Guarantor or its agent has provided the beneficial owner of such Company Preferred Securities or its nominee with at least 60 days' prior written notice of any opportunity to make such a declaration or claim. Section 4.08. Rights Not Separately Transferable. This Guarantee is a guarantee for the benefit of each Holder from time to time of Company Preferred Securities with respect to each Company Preferred Security held by such Holder. Upon transfer of any Company Preferred Securities to a third party, a Holder thereof shall no longer have any rights hereunder with respect to such Company Preferred Securities. The rights under this Guarantee with respect to a Company Preferred Security are not separately transferable from such Company Preferred Security. The Initial Holder, by its execution of this Guarantee, hereby accepts the rights under this Guarantee as initial purchaser and acquirer of the Company Preferred Securities with the understanding that such rights shall be transferred by operation of law to any subsequent Holder acquiring a Company Preferred Security from the Initial Holder or from a subsequent Holder of Company Preferred Securities. ARTICLE V LIMITATIONS OF TRANSACTIONS; RANKING Section 5.01. Section 5.01. Limitation of Transactions. -19- (a) The Guarantor, for so long as any Company Preferred Securities remain outstanding, shall not issue any preferred or preference shares ranking senior on liquidation to its obligations under this Guarantee or give any guarantee in respect of any preferred securities or preferred or preference shares issued by any of its subsidiaries if such guarantee would rank senior to this Guarantee, unless this Guarantee is amended to give the Holders of the Company Preferred Securities such rights and entitlements as are contained in or attached to such other guarantee so that this Guarantee ranks pari passu with such guarantee and pari passu on liquidation with any declared dividend or declared liquidation payments of such preferred or preference shares. (b) The Guarantor shall pay all amounts required to be paid pursuant to this Guarantee in respect of any Dividends on the Company Preferred Securities payable in respect of the most recent Dividend Period prior to any dividend or other payment (except dividends in the form of the Ordinary Shares) upon the Ordinary Shares. (c) The Guarantor, for so long as any Trust Preferred Securities or Company Preferred Securities remain outstanding, shall not (i) issue any liquidation preference participation rights (not being capital stock) ranking senior to or pari passu with the right to liquidation payments under its Parity Preferred Shares, (ii) create, incur or permit to exist any debt junior to its obligations under this Guarantee or (iii) create, incur or permit to exist any debt that ranks pari passu with this Guarantee unless such debt contains a provision substantially similar to proviso contained in Section 4.01. (d) The Guarantor, for so long as any Trust Preferred Securities or Company Preferred Securities remain outstanding, shall (i) maintain, or shall cause any one or more Qualified Subsidiaries (each, a "Potential Securityholder") to maintain, 100% ownership of the Company Common Securities. The Guarantor may transfer or permit the transfer of the Company Common Securities from one Potential Securityholder to another Potential Securityholder; provided that prior to such transfer it has received an opinion of a nationally recognized U.S. law firm experienced in such matters to the effect that (A) the Company will continue to be treated as a partnership for United States federal income tax purposes and such transfer will not cause the Company to be classified as an association or publicly traded partnership taxable as a corporation for United States federal income tax purposes, (B) such transfer will not cause the Company or the Trust to be required to register under the Investment Company Act and (C) such transfer will not adversely affect the limited liability of the Holders of the Company Preferred Securities. (e) The Guarantor, for so long as any Trust Preferred Securities or Company Preferred Securities remain outstanding, (i) shall use its commercially reasonable efforts to ensure that the Company will not be an association or a publicly traded partnership taxable as a corporation for United States federal income tax purposes, (ii) shall cause the Company to remain a limited liability company and not to voluntarily dissolve, wind up, liquidate or be terminated, except as permitted by the LLC Agreement and (iii) shall use its commercially reasonable efforts to ensure that the Trust will not be classified as other than a grantor trust for United States federal income tax purposes. -20- (f) The Guarantor, for so long as any of the Company Preferred Securities are outstanding, shall, to the fullest extent permitted by law, not permit, or take any action to cause, the dissolution, liquidation, termination or winding up of the Company, unless the Guarantor is itself in liquidation. (g) If the Company Preferred Securities are distributed to Holders of Trust Preferred Securities in connection with the involuntary or voluntary dissolution, winding-up or liquidation of the Trust, the Guarantor shall use its commercially reasonable efforts to cause the Company Preferred Securities to be listed on the Luxembourg Stock Exchange or on such other national securities exchange or similar organization as the Trust Preferred Securities are then listed or quoted on. Section 5.02. Ranking. (a) The Guarantee will constitute a general and unsecured obligation of UBS AG and, in liquidation of UBS AG, will rank, both as to payment and in liquidation: (i) subordinate and junior to all deposits and other liabilities of the Guarantor (including those in respect of bonds, notes and debentures that do not expressly rank pari passu with the obligations of the Guarantor under this Agreement); and (ii) senior to the Ordinary Shares and any other securities of the Guarantor expressed to rank junior to the most senior preference shares of the Guarantor (if any) from time to time outstanding. The foregoing liabilities that rank senior to the Guarantee are collectively called "UBS AG Senior Liabilities". (b) Payments under this Guarantee (other than payments upon a winding-up or dissolution, by bankruptcy or otherwise, in Switzerland of the Guarantor) are conditional upon the Guarantor not being in default in the payment of UBS AG Senior Liabilities and being Solvent at the time of payment. A report as to the insolvency of the Guarantor by two persons, each being a managing director, director or other authorized officer or agent of the Guarantor or employees of the independent accountants of the Guarantor will, in the absence of manifest error be treated and accepted by the Guarantor, the holders of Company Preferred Securities and all other interested parties as correct and sufficient evidence thereof. -21- ARTICLE VI TERMINATION Section 6.01. Termination. This Guarantee shall terminate upon, and be of no further force and effect from the earlier of (i) full payment of the Redemption Price of all Company Preferred Securities or purchase and cancellation of all Company Preferred Securities or (ii) upon full payment of the Liquidation Distribution, plus Additional Amounts thereon, if any, as payable upon liquidation of the Company. Notwithstanding the foregoing, this Guarantee will continue to be effective or will be reinstated, as the case may be, if at any time any Holder of Company Preferred Securities must restore payment of any sums paid under the Company Preferred Securities or under this Guarantee for any reason whatsoever. ARTICLE VII INDEMNIFICATION Section 7.01. Exculpation. (a) No Indemnified Person shall be liable, responsible or accountable in damages or otherwise to the Guarantor or any Covered Person for any loss, liability, expense, damage or claim incurred by reason of any act or omission performed or omitted by such Indemnified Person in good faith in accordance with this Guarantee and in a manner that such Indemnified Person reasonably believed to be within the scope of the authority conferred on such Indemnified Person by this Guarantee or by law, except that an Indemnified Person shall be liable for any such loss, liability, expense, damage or claim incurred by reason of such Indemnified Person's negligence or willful misconduct with respect to such acts or omissions. (b) An Indemnified Person shall be fully protected in relying in good faith upon the records of the Guarantor and upon such information, opinions, reports or statements presented to the Guarantor by any Person as to matters the Indemnified Person reasonably believes are within such other Person's professional or expert competence and who has been selected with reasonable care by or on behalf of the Guarantor, including information, opinions, reports or statements as to the value and amount of the assets, liabilities, profits, losses, or any other facts pertinent to the existence and amount of assets from which Dividends to Holders of Company Preferred Securities might properly be paid. Section 7.02. Indemnification. The Guarantor agrees to indemnify each Indemnified Person for, and to hold each Indemnified Person harmless against, any and all loss, liability, damage, claim or expense (including taxes other than taxes based on the income of any such Indemnified Person) incurred without negligence or bad faith on its -22- part, arising out of or in connection with the acceptance or administration of the trust or trusts hereunder, including the costs and expenses (including reasonable legal fees and expenses) of defending itself against, or investigating, any claim or liability in connection with the exercise or performance of any of its powers or duties hereunder. The obligation to indemnify as set forth in this Section 7.02 shall survive the termination of this Guarantee or the earlier resignation or removal of the Guarantee Trustee. ARTICLE VIII MISCELLANEOUS Section 8.01. Successors and Assigns. All guarantees and agreements contained in this Guarantee shall bind the successors, assigns, receivers, trustees and representatives of the Guarantor and shall inure to the benefit of the Holders of the Company Preferred Securities then outstanding. Section 8.02. Amendments. Except for those changes (i) required under Section 5.01(a) above, which may be made unilaterally by the Guarantor without the consent of the Holders of the Company Preferred Securities, or (ii) provided for in the two penultimate sentences of this paragraph, this Guarantee may be modified by the Guarantor and the Guarantee Trustee only with the prior approval of the Holders of not less than 662/3% in liquidation amount of the Company Preferred Securities (excluding any Company Preferred Securities held by the Guarantor or any of its Affiliates, other than Company Preferred Securities purchased or acquired by the Guarantor or its Affiliates in connection with transactions effected by or for the account of customers of the Guarantor or any of its Affiliates in connection with the distribution or trading of or market-making in connection with such securities and except that persons (other than Affiliates of the Guarantor) to whom the Guarantor or any of its subsidiaries have pledged Company Preferred Securities may vote or convert with respect to such pledged securities pursuant to the terms of such pledge). This Guarantee may be amended without the consent of the Holders of the Company Preferred Securities to (i) cure any ambiguity, (ii) correct or supplement any provision in this Guarantee that may be defective or inconsistent with any other provision of this Guarantee, (iii) add to the covenants, restrictions or obligations of the Guarantor, (iv) conform to any change in the Investment Company Act, the Trust Indenture Act or the rules or regulations of either such Act and (v) modify, eliminate and add to any provision of this Guarantee to such extent as may be necessary or desirable; provided that no such amendment made in reliance upon clause (v) above shall have a material adverse effect on the rights, preferences or privileges of the Holders of the Company Preferred Securities. Except as provided in the preceding sentence, Sections 4.01, 4.02, 4.07 and the form of Exhibit A may not be amended without the prior approval of each Holder of the Company Preferred Securities. Any amendment hereof in accordance with this Section 8.02 shall be binding on all Holders of Company Preferred Securities. Section 8.03.

(b) The obligations of the Guarantor in respect of any amount due to the Guarantee Trustee or any Holders under this Agreement shall, notwithstanding any judgment in a currency other than U.S. dollars, be discharged only to the extent that on the Business Day following receipt by the Guarantee Trustee or such Holders, as the case may be, of any amount adjudged to be so due in such other currency the Guarantee Trustee or such Holders, as the case may be, may in accordance with normal banking procedures purchase U.S. dollars with such other currency. (c) If the amount of U.S. dollars so purchased is less than the amount originally due to the Guarantee Trustee or such Holders, as the case may be, in U.S. dollars, the Guarantor agrees, to the fullest extent that it may effectively do so, as a separate obligation and notwithstanding any such judgment, to indemnify the Guarantee Trustee or such Holders, as the case may be, against such loss. (d) If the amount of dollars so purchased exceeds the amount originally due to the Guarantee Trustee or such Holders, as the case may be, in U.S. dollars, agree to remit any remaining amount to the Guarantor. Section 8.04. Assignment of the Guarantor. The Guarantor may not assign its obligations under the Guarantee, except in the case of a merger or consolidation where the Guarantor is not the surviving entity, or a sale of substantially all of its assets, and then only to the entity which is the survivor of such merger or consolidation or the Purchaser in such sale.
