ITEM 30.INDEMNIFICATION

Under the terms of the Delaware Statutory Trust Act (“DSTA”) and the Registrant’s Amended and Restated Agreement and Declaration of Trust, as amended (“Declaration of Trust”), no officer or trustee of the Registrant shall have any liability to the Registrant, its shareholders, or any other party for damages, except to the extent such limitation of liability is precluded by Delaware law, the Declaration of Trust or the By-Laws of the Registrant.

Subject to the standards and restrictions set forth in the Declaration of Trust, DSTA, Section 3817, permits a statutory trust to indemnify and hold harmless any trustee, beneficial owner or other person from and against any and all claims and demands whatsoever.  DSTA, Section 3803 protects trustees, officers, managers and other employees, when acting in such capacity, from liability to any person other than the Registrant or beneficial owner for any act, omission or

13

obligation of the Registrant or any trustee thereof, except as otherwise provided in the Declaration of Trust.

Indemnification of the Trustees and officers of the Registrant is provided for in Article VII, Sections 2 through 4 of the Registrant’s Declaration of Trust effective as of September 28, 2004, as amended, as follows:

Section 2. Indemnification and Limitation of Liability. The Trustees shall not be responsible or liable in any event for any neglect or wrong-doing of any officer, agent, employee, Manager or Principal Underwriter of the Trust, nor shall any Trustee be responsible for the act or omission of any other Trustee, and, subject to the provisions of the Bylaws, the Trust out of its assets may indemnify and hold harmless each and every Trustee and officer of the Trust from and against any and all claims, demands, costs, losses, expenses, and damages whatsoever arising out of or related to such Trustee’s performance of his or her duties as a Trustee or officer of the Trust; provided that nothing herein contained shall indemnify, hold harmless or protect any Trustee or officer from or against any liability to the Trust or any Shareholder to which he or she would otherwise be subject by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his or her office.

Every note, bond, contract, instrument, certificate or undertaking and every other act or thing whatsoever issued, executed or done by or on behalf of the Trust or the Trustees or any of them in connection with the Trust shall be conclusively deemed to have been issued, executed or done only in or with respect to their or his or her capacity as Trustees or Trustee, and such Trustees or Trustee shall not be personally liable thereon.

Section 3.  Trustee’s Good Faith Action, Expert Advice, No Bond or Surety.  The exercise by the Trustees of their powers hereunder shall be binding upon everyone interested in or dealing with the Trust.  A Trustee shall be liable to the Trust and to any Shareholder solely for his or her own willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of the office of Trustee and shall not be liable for errors of judgment or mistakes of fact or law.  The Trustees may take advice of counsel or other experts with respect to the meaning and operation of this Declaration of Trust and shall be under no liability for any act or omission in accordance with such advice nor for failing to follow such advice.  The Trustees shall not be required to give any bond as such, nor any surety if a bond is required.

Section 4.  Insurance.  The Trustees shall be entitled and empowered to the fullest extent permitted by law to purchase with Trust assets insurance for liability and for all expenses, reasonably incurred or paid or expected to be paid by a Trustee or officer in connection with any claim, action, suit or proceeding in which he or she becomes involved by virtue of his or her capacity or former capacity with the Trust, whether or not the Trust would have the power to indemnify him or her against such liability under the provisions of this Article.

14

Indemnification of Registrant’s advisors, custodian, transfer agent, accounting services provider, administrator and distributor against certain stated liabilities is provided for in the following documents:

(a)Each Series’ investment advisory agreement between the Registrant, on behalf of the series, and the Advisor, all of which are incorporated herein by reference, as follows:

(1)Section 6 of the Investment Advisory Agreement on behalf of the UBS International Sustainable Equity Fund (f/k/a UBS Global Sustainable Equity Fund (f/k/a UBS International Equity Fund)), dated April 25, 1995, as amended;

(2)Section 7 of the Investment Advisory Agreement on behalf of the UBS U.S. Sustainable Equity Fund, dated July 1, 2002;

(3)Section 7 of the Investment Advisory Agreement on behalf of the UBS U.S. Small Cap Growth Fund, dated July 1, 2002;

(4)Section 7 of the Investment Advisory Agreement on behalf of the UBS Global Allocation Fund, dated July 1, 2002;

(12)Section 7 of the Investment Advisory Agreement on behalf of the UBS US Dividend Ruler Fund

15

(13)Section 7 of the Investment Advisory Agreement on behalf of the UBS US Quality Growth At Reasonable Price Fund

(c)Section 9(a) of the Amended and Restated Principal Underwriting Contract between UBS Asset Management (US) Inc. and the Registrant on behalf of each series dated November 5, 2001, as amended and restated on October 12, 2018 which is incorporated herein by reference.

(e)Sections 8 and 9 of the Administration Contract between UBS Asset Management (Americas) Inc. (f/k/a UBS Global Asset Management (Americas) Inc.) and the Registrant on behalf of each series, which is incorporated herein by reference.

Insofar as indemnification for liability arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
