MORTGAGE-BACKED & US GOVERNMENT SECURITIES FUND FOR PUERTO

RICO RESIDENTS, INC.

AMENDED AND RESTATED INVESTMENT ADVISORY AGREEMENT

Amended and Restated Investment Advisory Agreement (the “Agreement”) made and entered into as of May 12, 2021, by and between Mortgage-Backed & US Government Securities Fund for Puerto Rico Residents, Inc. (the “Fund”), a corporation organized under the laws of the Commonwealth of Puerto Rico and a management investment company currently registering under the Investment Company Act of 1940, as amended (the “1940 Act”), and UBS Asset Managers of Puerto Rico, a division of UBS Trust Company of Puerto Rico (the “Adviser”), the Fund’s investment adviser, currently registering under the Investment Advisers Act of 1940, as amended (the “Advisers Act”).

WHEREAS, the Fund and the Adviser initially entered into the Investment Advisory Agreement as of November 4, 2004, when the Fund was registered under the Puerto Rico Investment Companies Act and subject to the rules and regulations thereunder;

WHEREAS, the Fund is registered under the 1940 Act as a closed-end management investment company and the Adviser is registered under the Advisers Act;

WHEREAS, the Fund desires to retain the Adviser as investment adviser to furnish investment advisory services to the Fund; and

WHEREAS, the Adviser has full capacity and is willing to provide investment advisory services to the Fund on the terms and conditions set forth herein.

NOW, THEREFORE, in consideration of the premises and mutual covenants herein contained, it is agreed between the parties hereto as follows.

1. Appointment. The Fund hereby appoints the Adviser as investment adviser of the Fund for the period and on the terms set forth in this Agreement. The Adviser accepts such appointment and agrees to render the services set forth herein for the compensation provided herein.

2. Duties as Investment Adviser.

(a) Subject to the supervision of the Fund’s Board of Directors (the “Board”), the Adviser will provide a complete and continuous investment program for the Fund, including investment research and management with respect to all securities and investments and cash equivalents of the Fund.

(b) The Adviser agrees that in placing orders with brokers and dealers, it will attempt to obtain the best net price and most favorable execution, provided that, subject to the provisions of the 1940 Act, the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and to the extent permitted by the Securities and Exchange Commission, (the “SEC”), the Adviser may purchase and sell portfolio securities to and from brokers who provide the Adviser with research analysis, statistical or pricing advice, or similar services. The Adviser will consider the

full range and quality of a broker’s or dealer’s services. Factors considered by the Adviser in selecting brokers and dealers may include the following: price, the broker’s or dealer’s facilities, the brokers or dealers reliability and financial responsibility, the ability of the broker or dealer to effect securities transactions, particularly with regard to such aspects as timing, order size and execution of orders, and the research and other services provided by that broker or dealer to the Adviser, notwithstanding that the Fund may not be the direct or exclusive beneficiary of those services. The Adviser will not be obligated to seek in advance competitive bidding or the most favorable commission rate applicable to any particular transaction for the Fund or to select any broker or dealer on the basis of its “posted” commission rate. The Adviser may cause the Fund to pay a commission for effecting a transaction for the Fund in excess of the amount another broker or dealer would have charged for effecting the transaction, provided that the Adviser determines in good faith that such commission is reasonable in relation to the value of the brokerage and/or research services provided by the broker or dealer to the Adviser. Research services furnished by the brokers or dealers through which the Fund effects securities transactions may be used by the Adviser in advising its other clients (including persons affiliated with the Adviser), and conversely, such research services furnished to the Adviser in connection with other clients may be used in advising the Fund. The Adviser will seek to allocate the opportunity to purchase or sell a security or other investment among advisory clients in accordance with the Adviser’s trade allocation policies and procedures so that accounts with like investment strategies are treated fairly and equitably overtime. In the event it is not possible to obtain the same price or time of execution for all of the securities or other investments purchased or sold for the Fund, transactions for the Fund may be reported by using the average price of these transactions. The Adviser may purchase or sell the same security for more than one client on an aggregated basis to obtain a favorable price to the extent permitted by applicable law. These orders may be averaged as to price and allocated as to amount according to each client’s daily purchase or sale orders or upon some other basis deemed equitable by the Adviser.

(c) Subject to the provisions of the 1940 Act, the Exchange Act and to the extent permitted by the SEC, the Adviser may engage on behalf of the Fund in securities and other transactions with its affiliates (or other dealers) and transactions in securities for which one of its affiliates is a member of the underwriting syndicate. In no instance will portfolio securities or other investments be purchased from or sold to the Adviser or any of its affiliates or with any party with whom the Adviser has entered into an agreement pursuant to Section 5 of this Agreement or affiliated person thereof, except in accordance with applicable law and the policies and procedures adopted by the Board.

(d) In compliance with the requirements of Rule 31a-3 under the 1940 Act, the Adviser ▇▇▇▇▇▇ agrees that all records which it maintains for the Fund are the property of the Fund and further agrees to surrender promptly to the Fund any such records upon the Fund’s request. Adviser further agrees to preserve for the periods prescribed by Rule 31a-2 under the 1940 Act the records required to be maintained by Rule 3la-1 under the 1940 Act.

(e) The Adviser will provide the Fund’s administrator with any assistance regarding the valuation of the Fund’s portfolio investments as the latter may reasonably request.

3. Custodian. The Adviser is authorized, in its capacity as investment adviser, to give instructions to the Fund’s custodian with respect to all investment decisions regarding the Fund.

4. Further Duties. In all matters relating to the performance of this Agreement, the Adviser will act in conformity with the Fund’s Certificate of Incorporation (the “Certificate”), as the Certificate may be amended from time to time, By-Laws, Code of Ethics, policies and procedures adopted by the Board, the then current prospectus, the 1940 Act and the rules and regulations thereunder, the Exchange Act and the rules and regulations thereunder, and any other applicable laws and regulations of the United States and Puerto Rico.

5. Retention by the Adviser of a Sub-Investment Adviser. The Adviser may from time to time, in its sole discretion to the extent permitted by applicable law, appoint one or more sub-advisers, including, without limitation, affiliates of the Adviser, to perform investment advisory services with respect to the Fund; provided, however, that the compensation of such person or persons shall be paid by the Adviser and that the Adviser shall be as fully responsible to the Fund for the acts and omissions of any sub-adviser as it is for its own acts and omissions. The Adviser may terminate any or all sub-advisers in its sole discretion at any time to the extent permitted by applicable law. The Adviser will disclose fully to the Board in advance the terms of any agreement entered into pursuant to this Section including, but not limited to, the compensation to be paid, and will notify the Board in advance of any change in the terms of such agreement.

6. Services Not Exclusive. The services furnished by the Adviser hereunder are not to be deemed exclusive and the Adviser shall be free to furnish smiler services to others so long as its services under this Agreement are not materially impaired thereby. Nothing in this Agreement shall limit or restrict the right of any director, officer, or employee of the Adviser, who may also be a director, officer, or employee of the Fund, to engage in any other business or to devote his or her time and attention in pan to the management or other aspects of any other business, whether of a similar nature or a dissimilar nature.
