RE:

Subadvisory Agreement

Ladies and Gentlemen:

Virtus Managed Account Completion Shares (MACS) Trust (the “Trust”) is an open-end investment company of the series type registered under the Investment Company Act of 1940, as amended (the “Act”), and is subject to the rules and regulations promulgated thereunder. The shares of the Trust are offered or may be offered in several series (sometimes hereafter referred to as the “Series”), including ▇▇▇▇▇▇ ▇▇▇▇▇ Harbor EMD MACS and ▇▇▇▇▇▇ ▇▇▇▇▇ Harbor EMD Sovereign MACS.

Virtus Investment Advisers, Inc. (the “Adviser”) evaluates and recommends series advisers for the Series and is responsible for the day-to-day management of the Series.

Appointment as a Subadviser. The Adviser, being duly authorized, hereby appoints Stone Harbor Investment Partners, a division of Virtus Fixed Income Advisers LLC (the “Subadviser”) as a discretionary series adviser to invest and reinvest the assets of the Series designated by the Adviser as set forth on Schedule E attached hereto (the “Designated Series”) on the terms and conditions set forth herein. The services of the Subadviser hereunder are not to be deemed exclusive; the Subadviser may render services to others and engage in other activities that do not conflict in any material manner with the Subadviser’s performance hereunder.

Acceptance of Appointment; Standard of Performance. The Subadviser accepts its appointment as a discretionary series adviser of the Designated Series and agrees, subject to the oversight of the Board of Trustees of the Trust (the “Board”) and the Adviser, to use its best professional judgment to make investment decisions for the Designated Series in accordance with the provisions of this Agreement and as set forth in Schedule C attached hereto and made a part hereof. The Subadviser shall for all purposes herein be deemed to be an independent contractor and shall, except as expressly provided or authorized (whether herein or otherwise), have no authority or obligation to act for or represent the Adviser, the Trust or the Series in any way.

Services of Subadviser. In providing management services to the Designated Series, the Subadviser shall be subject to the investment objectives, policies and restrictions of the Trust as they apply to the Designated Series and as set forth in the Trust’s then current prospectus (“Prospectus”) and statement of additional information (“Statement of Additional Information”) filed with the Securities and Exchange Commission (the “SEC”) as part of the Trust’s registration statement (the “Registration Statement”), as may be periodically amended and provided to the Subadviser by the Adviser, and to the investment restrictions set forth in the Act and the Rules thereunder, to the supervision and control of the Board, and to instructions from the Adviser. The Subadviser shall not, without the Trust’s prior written approval, effect any transactions that would cause the Designated Series at the time of the transaction to be out of compliance with any of such restrictions or policies.

Transaction Procedures. All series transactions for the Designated Series shall be consummated by payment to, or delivery by, the custodian(s) from time to time designated by the Trust (the “Custodian”), or such depositories or agents as may be designated by the Custodian in writing, of all cash and/or securities due to or from the Designated Series. The Subadviser shall not have possession or custody of such cash and/or securities or any responsibility or liability with respect to such custody. The Subadviser shall advise the Custodian and confirm in writing to the Trust all investment orders for the Designated Series placed by it with brokers and dealers at the time and in the manner set forth in Schedule A hereto (as amended from time to time). The Trust shall issue to the Custodian such instructions as may be appropriate in connection with the settlement of any transaction initiated by the Subadviser. The Trust shall be responsible for all custodial arrangements and the payment of all custodial charges and fees, and, upon giving proper instructions to the Custodian, the Subadviser shall have no responsibility or liability with respect to custodial arrangements or the acts, omissions or other conduct of the Custodian.

Allocation of Brokerage. The Subadviser shall have authority and discretion to select brokers and dealers to execute Designated Series transactions initiated by the Subadviser, and to select the markets on or in which the transactions will be executed.

In placing orders for the sale and purchase of Designated Series securities for the Trust, the Subadviser’s primary responsibility shall be to seek the best execution of orders at the most favorable prices. However, this responsibility shall not obligate the Subadviser to solicit competitive bids for each transaction or to seek the lowest available commission cost to the Trust, as long as the Subadviser reasonably believes that the broker or dealer selected by it can be expected to obtain a “best execution” market price on the particular transaction and determines in good faith that the commission cost is reasonable in relation to the value of the brokerage and research services (as defined in Section 28(e)(3) of the Securities Exchange Act of 1934, as amended) provided by such broker or dealer to the Subadviser, viewed in terms of either that particular transaction or of the Subadviser’s overall responsibilities with respect to its clients, including the Trust, as to which the Subadviser exercises investment discretion, notwithstanding that the Trust may not be the direct or exclusive beneficiary of any such services or that another broker may be willing to charge the Trust a lower commission on the particular transaction.

The Subadviser may manage other portfolios and expects that the Trust and other portfolios the Subadviser manages will, from time to time, purchase or sell the same securities. The Subadviser may aggregate orders for the purchase or sale of securities on behalf of the Designated Series with orders on behalf of other portfolios the Subadviser manages. Securities purchased or proceeds of securities sold through aggregated orders, as well as expenses incurred in the transaction, shall be allocated to the account of each portfolio managed by the Subadviser that bought or sold such securities in a manner considered by the Subadviser to be equitable and consistent with the Subadviser’s fiduciary obligations in respect of the Designated Series and to such other accounts.

The Subadviser shall not execute any transactions for the Designated Series with a broker or dealer that is an “affiliated person” (as defined in the Act) of (i) the Designated Series; (ii) another Series; (iii) the Adviser; (iv) the Subadviser or any other subadviser to the Designated Series; (v) a principal underwriter of the Trust’s shares; or (vi) any other affiliated person of the Designated Series, in each case, unless such transactions are permitted by applicable law or regulation and carried out in compliance with any applicable policies and procedures of the Trust. The Trust shall provide the Subadviser with a list of brokers and dealers that are “affiliated persons” of the Trust, the Adviser or the principal underwriter, and applicable policies and procedures. Upon the request of the Adviser, the Subadviser shall promptly, and in any event within three business days of a request, indicate whether any entity identified by the Adviser in such request is an “affiliated person,” as such term is defined in the Act, of (i) the Subadviser or (ii) any affiliated person of the Subadviser, subject in each case to any confidentiality requirements applicable to the Subadviser and/or its affiliates. Further, the Subadviser shall provide the Adviser with a list of (x) each broker-dealer entity that is an “affiliated person,” as such term is defined in the Act, of the Subadviser and (y) each affiliated person of the Subadviser that has outstanding publicly-issued debt or equity. Each of the Adviser and the Subadviser agrees promptly to update such list(s) whenever the Adviser or the Subadviser becomes aware of any changes that should be added to or deleted from such list of affiliated persons.

Consistent with its fiduciary obligations to the Trust in respect of the Designated Series and the requirements of best price and execution, the Subadviser may, under certain circumstances, arrange to have purchase and sale transactions effected directly between the Designated Series and another account managed by the Subadviser (“cross transactions”), provided that such transactions are carried out in accordance with applicable law or regulation and any applicable policies and procedures of the Trust. The Trust shall provide the Subadviser with applicable policies and procedures.

Proxies and Other Shareholder Actions.

Unless the Adviser or the Trust gives the Subadviser written instructions to the contrary, the Subadviser, or a third party designee acting under the authority and supervision of the Subadviser, shall review all proxy solicitation materials and be responsible for voting and handling all proxies in relation to the assets of the Designated Series. Unless the Adviser or the Trust gives the Subadviser written instructions to the contrary, provided that the Adviser has reviewed the Subadviser’s proxy voting procedures then in effect and determined them to comply with the requirements of the Trust’s proxy voting policy, the Subadviser will, in compliance with the Subadviser’s proxy voting procedures then in effect, vote or abstain from voting, all proxies solicited by or with respect to the issuers of securities in which assets of the Designated Series may be invested. The Adviser shall cause the Custodian, the Administrator or another party, to forward promptly to the Subadviser all proxies upon receipt, so as to afford the Subadviser a reasonable amount of time in which to determine how to vote such proxies. The Subadviser agrees to provide the Adviser in a timely manner with any changes to the Subadviser’s proxy voting procedures. The Subadviser further agrees to provide the Adviser in a timely manner with a record of votes cast containing all of the voting information required by Form N-PX in an electronic format to enable the Trust to file Form N-PX as required by Rule 30b1-4 under the Act. The Subadviser shall provide disclosure regarding its proxy voting policies and procedures in accordance with the requirements of Form N-1A for inclusion in the Registration Statement of the Trust. During any annual period in which the Subadviser has voted proxies for the Trust, the Subadviser shall, as may reasonably be requested by the Adviser, certify as to its compliance with its proxy voting policies and procedures and applicable federal statutes and regulations.

The Subadviser is authorized to deal with reorganizations, exchange offers and other voluntary corporate actions with respect to securities held in the Designated Series in such manner as the Subadviser deems advisable, unless the Trust or the Adviser otherwise specifically directs in writing. It is acknowledged and agreed that the Subadviser shall not be responsible for the filing of claims (or otherwise causing the Trust to participate) in class action settlements or similar proceedings in which shareholders may participate related to securities currently or previously associated with the Designated Series. With the Adviser’s approval, on a case-by-case basis the Subadviser may obtain the authority and take on the responsibility to: (i) identify, evaluate and pursue legal claims, including commencing or defending suits, affecting the securities held at any time in the Designated Series, including claims in bankruptcy, class action securities litigation and other litigation; (ii) participate in such litigation or related proceedings with respect to such securities as the Subadviser deems appropriate to preserve or enhance the value of the Designated Series, including filing proofs of claim and related documents and serving as “lead plaintiff” in class action lawsuits; (iii) exercise generally any of the powers of an owner with respect to the supervision and management of such rights or claims, including the settlement, compromise or submission to arbitration of any claims, the exercise of which the Subadviser deems to be in the best interest of the Designated Series or required by applicable law, including ERISA, and (iv) employ suitable agents, including legal counsel, and to pay their reasonable fees, expenses and related costs from the Designated Series.

Prohibited Conduct. In accordance with Rule 12d3-1 and Rule 17a-10 under the 1940 Act and any other applicable law or regulation, the Subadviser’s responsibility regarding investment advice hereunder is limited to the Designated Series, and the Subadviser will not consult with any other investment advisory firm that provides investment advisory services to the Trust or any other investment company sponsored by Virtus Investment Partners, Inc. or its affiliates regarding transactions in securities or other assets for the Trust. The Trust shall provide the Subadviser with a list of investment companies sponsored by Virtus Investment Partners, Inc. and its affiliates, and the Subadviser shall be in breach of the foregoing provision only if the investment company is

included in such a list provided to the Subadviser prior to such prohibited action. The Subadviser, and its affiliates and agents, shall refrain from making any written or oral statements concerning the Designated Series, the Trust, any other investment company sponsored by Virtus Investment Partners, Inc. or its affiliates, and any substantially similar products, that are reasonably likely to mislead investors regarding either (i) the services rendered by the Subadviser to the Designated Series or the Trust, or (ii) the Designated Series, including without limitation with respect to the investment strategies and/or risks, and/or the performance thereof. In addition, the Subadviser shall not, without the prior written consent of the Trust and the Adviser, delegate any obligation assumed pursuant to this Agreement to any affiliated or unaffiliated third party. The parties acknowledge and agree that the Subadviser may, in its discretion, utilize personnel employed by affiliates of the Subadviser to perform services pursuant to this Agreement by way of a “participating affiliate” agreement in accordance with, and to the extent permitted by, the Act and the Investment Advisers Act of 1940, as amended (the “Advisers Act”), including the published interpretations thereof by the SEC or its staff. Such participating affiliate agreement shall subject the personnel providing such services to the Subadviser’s compliance and other programs with respect to their activities on behalf of the Designated Series. For the avoidance of doubt, it is acknowledged and agreed that the Subadviser assumes full responsibility for all actions, and any failure to act, by each person utilized by the Subadviser to perform services under this Agreement.

Information and Reports.

The Subadviser shall keep the Trust and the Adviser informed of developments relating to its duties as Subadviser of which the Subadviser has, or should have, knowledge that would materially affect the Designated Series. In this regard, the Subadviser shall provide the Trust, the Adviser and their respective officers with such periodic reports concerning the obligations the Subadviser has assumed under this Agreement as the Trust and the Adviser may from time to time reasonably request. In addition, prior to each meeting of the Board, the Subadviser shall provide the Adviser and the Board with reports regarding the Subadviser’s management of the Designated Series during the most recently completed quarter, which reports: (i) shall include Subadviser’s representation that its performance of its investment management duties hereunder is in compliance with the Designated Series’ investment objectives and practices, the Act and applicable rules and regulations under the Act, and the diversification and minimum “good income” requirements of Subchapter M under the Internal Revenue Code of 1986, as amended, and (ii) otherwise shall be in such form as may be reasonably required by the Adviser.

Each of the Adviser and the Subadviser shall provide the other party with a list, to the best of the Adviser’s or the Subadviser’s respective knowledge, of each affiliated person (and any affiliated person of such an affiliated person) of the Adviser or the Subadviser, as the case may be, and each of the Adviser and Subadviser agrees promptly to update such list whenever the Adviser or the Subadviser becomes aware of any changes that should be added to or deleted from the list of affiliated persons.

The Subadviser shall also provide the Adviser with any information reasonably requested by the Adviser regarding its management of the Designated Series required for any shareholder report, amended Registration Statement, or Prospectus supplement to be filed by the Trust with the SEC.

The Subadviser shall promptly notify the Adviser and the Trust in the event that any of the Subadviser’s employees or contractors raise any issues concerning any actual or potential material violation of any law, regulation or internal policy of the Subadviser, in each case actually or potentially affecting the Designated Series.

Fees for Services. No fee shall be payable to the Subadviser for its services under this Agreement.

10.

Limitation of Liability. Absent the Subadviser’s breach of this Agreement or the willful misconduct, bad faith, gross negligence, or reckless disregard of the obligations or duties hereunder on the part of the Subadviser, or its officers, directors, partners, agents, employees and controlling persons, the Subadviser shall not be liable for any act or omission in the course of, or connected with, rendering services hereunder or for any losses that may be sustained in the purchase, holding or sale of any position; provided, however, that the Subadviser shall be responsible for, and shall indemnify and hold the Trust and the Adviser and each of their respective directors

or trustees, members, officers, employees and shareholders, and each person, if any, who controls the Trust or the Adviser within the meaning of Section 15 of the Securities Act of 1933, as amended (the “Securities Act”), harmless against, any and all Losses (as defined below) arising out of or resulting from a “Trade Error” (as defined in the compliance policies and procedures of the Trust), as the same may be amended from time to time) caused by the negligent action or negligent omission of the Subadviser or its agent. The Adviser agrees to provide prior written notice to the Subadviser of any material changes to the definition of Trade Error becoming effective with respect to the Designated Series unless, in the reasonable discretion of the Adviser, such change must become effective earlier due to any applicable law, rule, regulation or court order. It is acknowledged and agreed that any Trade Error that results in a gain to the Designated Series shall inure to the benefit of the Designated Series. For the avoidance of doubt, it is acknowledged and agreed that the Designated Series is a third party beneficiary of the indemnity granted in this Section 10, and the indemnity is intended to cover claims by the Designated Series, the Trust (on behalf of the Designated Series), or the Adviser against the Subadviser for recovery pursuant to this section.

11.

Confidentiality. Subject to the duty of the Subadviser and the Trust to comply with applicable law, including any demand of any regulatory or taxing authority having jurisdiction, the parties hereto shall treat as confidential all information pertaining to the Designated Series and the actions of the Subadviser and the Trust in respect thereof. Notwithstanding the foregoing, the Trust and the Adviser agree that the Subadviser may (i) disclose in marketing materials and similar communications that the Subadviser has been engaged to manage assets of the Designated Series pursuant to this Agreement, and (ii) include performance statistics regarding the Designated Series in composite performance statistics regarding one or more groups of Subadviser’s clients published or included in any of the foregoing communications, provided that the Subadviser does not identify any performance statistics as relating specifically to the Designated Series.

12.

Assignment. This Agreement shall terminate automatically in the event of its assignment, as that term is defined in Section 2(a)(4) of the Act. The Subadviser shall notify the Trust and the Adviser in writing sufficiently in advance of any proposed change of control, as defined in Section 2(a)(9) of the Act, as will enable the Trust to consider whether an assignment as defined in Section 2(a)(4) of the Act will occur, and to take the steps necessary to enter into a new contract with the Subadviser.

13.

Representations, Warranties and Agreements of the Subadviser. The Subadviser represents, warrants and agrees that:

It is duly organized, validly existing, and in good standing under the laws of the jurisdiction of its organization, and is qualified to do business in each jurisdiction in which failure to be so qualified would reasonably be expected to have a material adverse effect upon it. It (i) is registered as an “investment adviser” under the Investment Advisers Act of 1940, as amended (“Advisers Act”) and will continue to be so registered for so long as this Agreement remains in effect; (ii) is not prohibited by the Act or the Advisers Act from performing the services contemplated by this Agreement; provided, however, that the Subadviser makes no representation or warranty with regard to the approval of this Agreement by the Board under Section 15 of the Act; (iii) has appointed a Chief Compliance Officer under Rule 206(4)-7 under the Advisers Act; (iv) has adopted written policies and procedures that are reasonably designed to prevent violations of the Advisers Act from occurring, and correct promptly any violations that have occurred, and will provide notice promptly to the Adviser of any material violations relating to the Trust; (v) has materially met and will seek to continue to meet for so long as this Agreement remains in effect, any other applicable federal or state requirements, or the applicable requirements of any regulatory or industry self-regulatory agency.

It is either registered as a commodity trading advisor or duly exempt from such registration with the U.S. Commodity Futures Trading Commission (“CFTC”), and it will maintain such registration or exemption continuously during the term of this Agreement or, alternatively, will become a commodity trading advisor duly registered with the CFTC and will be a member in good standing with the National Futures Association.

It will maintain, keep current and preserve on behalf of the Trust, records in the manner required or permitted by the Act and the Rules thereunder including the records identified in Schedule B (as Schedule B may be amended from time to time). The Subadviser agrees that such records are the property of the Trust, and shall be surrendered to the Trust or to the Adviser as agent of the Trust promptly upon request of either. The Trust acknowledges that the Subadviser may retain copies of all records required to meet the record retention requirements imposed by law and regulation.

It shall maintain a written code of ethics (the “Code of Ethics”) complying with the requirements of Rule 204A-1 under the Advisers Act and Rule 17j-1 under the Act and shall provide the Trust and the Adviser with a copy of the Code of Ethics and evidence of its adoption. It shall institute procedures reasonably necessary to prevent Access Persons (as defined in Rule 17j-1) from violating its Code of Ethics. The Subadviser acknowledges receipt of the written code of ethics adopted by and on behalf of the Trust. Each calendar quarter while this Agreement is in effect, a duly authorized compliance officer of the Subadviser shall certify to the Trust and to the Adviser that the Subadviser has complied with the requirements of Rules 204A-1 and 17j-1 during the previous calendar quarter and that there has been no material violation of its Code of Ethics, or of Rule 17j-1(b), or that any persons covered under its Code of Ethics has divulged or acted upon any material, non-public information, as such term is defined under relevant securities laws, and if such a violation of the code of ethics of the Trust has occurred, or if such a violation of its Code of Ethics has occurred, that appropriate action was taken in response to such violation. The Subadviser shall notify the Adviser promptly of any material violation of the Code of Ethics involving the Trust. The Subadviser will provide such additional information regarding violations of the Code of Ethics directly affecting the Trust as the Trust or its Chief Compliance Officer on behalf of the Trust or the Adviser may reasonably request in order to assess the functioning of the Code of Ethics or any harm caused to the Trust from a violation of the Code of Ethics. Further, the Subadviser represents that it has policies and procedures regarding the detection and prevention of the misuse of material, nonpublic information by the Subadviser and its employees. The Subadviser will explain what it has done to seek to ensure such compliance in the future. Annually, the Subadviser shall furnish to the Trust and the Adviser a written report which complies with the requirements of Rule 17j-1 concerning the Subadviser’s Code of Ethics. The Subadviser shall permit the Trust and the Adviser to examine the reports required to be made by the Subadviser under Rules 204A-1(b) and 17j-1(d)(1) and this subparagraph.

It has adopted and implemented, and throughout the term of this Agreement shall maintain in effect and implement, policies and procedures reasonably designed to prevent, detect and correct violations by the Subadviser and its supervised persons, and, to the extent the activities of the Subadviser in respect of the Trust could affect the Trust, by the Trust, of “federal securities laws” (as defined in Rule 38a-1 under the Act), and that the Subadviser has provided the Trust with true and complete copies of its policies and procedures (or summaries thereof) and related information reasonably requested by the Trust and/or the Adviser. The Subadviser agrees to cooperate with periodic reviews by the Trust’s and/or the Adviser’s compliance personnel of the Subadviser’s policies and procedures, their operation and implementation and other compliance matters and to provide to the Trust and/or the Adviser from time to time such additional information and certifications in respect of the Subadviser’s policies and procedures, compliance by the Subadviser with federal securities laws and related matters as the Trust’s and/or the Adviser’s compliance personnel may reasonably request. The Subadviser agrees to promptly notify the Adviser of any compliance violations which affect the Designated Series.

The Subadviser will immediately notify the Trust and the Adviser of the occurrence of any event which would disqualify the Subadviser from serving as an investment adviser of an investment company pursuant to Section 9 of the Act or otherwise. The Subadviser will also immediately notify the Trust and the Adviser if it is served or otherwise receives notice of any action, suit, proceeding, inquiry or investigation, at law or in equity, before or by any court, public board or body, including but not limited to the SEC and the CFTC, involving the affairs of the Designated Series.

To the best of its knowledge, there are no material pending, threatened, or contemplated actions, suits, proceedings, or investigations before or by any court, governmental, administrative or self-regulatory body, board of trade, exchange, or arbitration panel to which it or any of its directors, officers, employees, partners, shareholders, members or principals, or any of its affiliates is a party or to which it or its affiliates or any of its or its affiliates’ assets are subject, nor has it or any of its affiliates received any notice of an investigation, inquiry, or dispute by any court, governmental, administrative, or self-regulatory body, board of trade, exchange, or arbitration panel regarding any of its or their activities, which might reasonably be expected to result in (i) a material adverse effect on the Trust or (ii) a material adverse change in the Subadviser’s condition (financial or otherwise) or business, or which might reasonably be expected to materially impair the Subadviser’s ability to discharge its obligations under this Agreement. The Subadviser will also immediately notify the Trust and the Adviser if the representation in this Section 13.G is no longer accurate.

The Subadviser shall promptly notify the Adviser of any changes in its executive officers, partners or in its key personnel, including, without limitation, any change in the portfolio manager(s) responsible for the Designated Series or if there is an actual or expected change in control or management of the Subadviser.

14.

No Personal Liability. Reference is hereby made to the Declaration of Trust establishing the Trust, a copy of which has been filed with the SEC, and to any and all amendments thereto so filed or hereafter filed. The name “Virtus Managed Account Completion Shares (MACS) Trust” refers to the Board under said Declaration of Trust, as trustees and not personally, and no trustee, shareholder, officer, agent or employee of the Trust shall be held to any personal liability in connection with the affairs of the Trust; only the trust estate under said Declaration of Trust is liable. Without limiting the generality of the foregoing, neither the Subadviser nor any of its officers, directors, partners, shareholders or employees shall, under any circumstances, have recourse or cause or willingly permit recourse to be had directly or indirectly to any personal, statutory, or other liability of any shareholder, Trustee, officer, agent or employee of the Trust or of any successor of the Trust, whether such liability now exists or is hereafter incurred for claims against the trust estate.

15.

Entire Agreement; Amendment. This Agreement, together with the Schedules attached hereto, constitutes the entire agreement of the parties with respect to the subject matter hereof and supersedes any prior written or oral agreements pertaining to the subject matter of this Agreement. This Agreement may be amended at any time, but only by written agreement among the Subadviser, the Adviser and the Trust, which amendment, other than amendments to Schedules A, B, D, E and F, is subject to the approval of the Board (including those trustees who are not “interested persons” of the Trust) and, if required by the Act or applicable SEC rules and regulations, a vote of a majority of the Designated Series’ outstanding voting securities; provided, however, that, notwithstanding the foregoing, this Agreement may be amended or terminated in accordance with any exemptive order issued to the Adviser, the Trust or its affiliates.

16.

Effective Date; Term. This Agreement shall become effective on the date set forth on the first page of this Agreement, and shall continue in effect for an initial period of two years. The Agreement shall continue from year to year thereafter only so long as its continuance has been specifically approved at least annually (i) by a vote of the Board of the Trust or by vote of a majority of outstanding voting securities of the Designated Series and (ii) by vote of a majority of the trustees who are not interested persons of the Trust (as defined in the Act) or of any person party to this Agreement, cast in person (or otherwise, as consistent with applicable laws, regulations and related guidance and relief) at a meeting called for the purpose of such approval.

17.

Termination. This Agreement may be terminated at any time without payment of any penalty (i) by the Board, or by a vote of a majority of the outstanding voting securities of the Designated Series, upon 60 days’ prior written notice to the Adviser and the Subadviser, (ii) by the Subadviser upon 60 days’ prior written notice to the Adviser and the Trust, or (iii) by the Adviser upon 60 days’ prior written notice to the Subadviser. This Agreement may also be terminated, without the payment of any penalty, by the Adviser

or the Board immediately (i) upon the material breach by the Subadviser of this Agreement or (ii) at the terminating party’s discretion, if the Subadviser or any officer, director or key portfolio manager of the Subadviser is accused in any regulatory, self-regulatory or judicial investigation or proceeding as having violated the federal securities laws or engaged in criminal conduct. This Agreement shall terminate automatically and immediately upon termination of the Advisory Agreement. This Agreement shall terminate automatically and immediately in the event of its assignment, as such term is defined in and interpreted under the terms of the 1940 Act and the rules promulgated thereunder. Termination of this Agreement will not affect any outstanding orders or transactions or any legal rights or obligations which may already have arisen. Transactions in progress at the date of termination will be completed by the Subadviser as soon as reasonably practicable. Provisions of this Agreement relating to indemnification and the preservation of records, as well as any responsibilities or obligations of the parties hereto arising from matters initiated prior to termination, shall survive any termination of this Agreement.

18.

Applicable Law. To the extent that state law is not preempted by the provisions of any law of the United States heretofore or hereafter enacted, as the same may be amended from time to time, this Agreement shall be administered, construed and enforced according to the laws of the State of Delaware applicable to contracts entered into and fully performed within the State of Delaware.

19.

Severability. If any term or condition of this Agreement shall be invalid or unenforceable to any extent or in any application, then the remainder of this Agreement shall not be affected thereby, and each and every term and condition of this Agreement shall be valid and enforced to the fullest extent permitted by law.

20.

OPERATIONAL PROCEDURES

In order to minimize operational problems, it will be necessary for a flow of information to be supplied in a secure manner by Subadviser to the Trust’s service providers, including: The Bank of New York Mellon (the “Custodian”), Virtus Fund Services, LLC (the “Fund Administrator”), BNY Mellon Investment Servicing (US) Inc., (the “Accounting Agent”), any Prime Broker to the Series, and all other Counterparties/Brokers as required.

The Subadviser must furnish the Trust’s service providers with required daily information as to executed trades in a format and time-frame agreed to by the Subadviser, Custodian, Fund Administrator, Accounting Agent and Prime Broker/Counterparties and designated persons of the Trust. Trade information sent to the Custodian, Fund Administrator, Accounting Agent and Prime Broker/Counterparties must include all necessary data within the required timeframes to allow such parties to perform their obligations to the Designated Series.

The Accounting Agent specifically requires a daily trade blotter with a summary of all trades, in addition to trade feeds, including, if no trades are executed, a report to that effect. Daily information as to executed trades for same-day settlement and future trades must be sent to the Accounting Agent no later than 5:00 p.m. (Eastern Time) on the day of the trade each day the Trust is open for business. All other executed trades must be delivered to the Accounting Agent on trade date +1 by 11:00 a.m. (Eastern Time) to ensure that they are part of the Designated Series’ NAV calculation. (Subadviser will be responsible for reimbursement to the Trust for any loss caused by the Subadviser’s failure to comply with the requirements of this Schedule A.) On fiscal quarter ends and calendar quarter ends, all trades must be delivered to the Accounting Agent by 4:30 p.m. (Eastern Time) for inclusion in the financial statements of the Designated Series. The data to be sent to the Accounting Agent and/or Fund Administrator will be as agreed by the Subadviser, Fund Administrator, Accounting Agent and designated persons of the Trust and shall include (without limitation) the following:

1.	Transaction type (e.g., purchase, sale, open, close, put call);
2.	Security type (e.g., equity, fixed income, swap, future, option, short, long);
3.	Security name;
4.	Exchange identifier (e.g., CUSIP, ISIN, Sedol, OCC Symbol) (as applicable);
5.	Number of shares and par, original face, contract amount, notional amount;
6.	Transaction price per share (clean if possible);
7.	Strike price;
8.	Aggregate principal amount;
9.	Executing broker;
10.	Settlement agent;
11.	Trade date;
12.	Settlement date;
13.	Aggregate commission or if a net trade;
14.	Interest purchased or sold from interest bearing security;
15.	Net proceeds of the transaction;

17.	Derivative terms;
18.	Non-deliverable forward classification (to be provided quarterly);
19.	Maturity/expiration date; and

When opening accounts with brokers for, and in the name of, the Trust, the account must be a cash account. No margin accounts are to be opened by the Subadviser in the name of the Trust or any Series except as specifically approved by the Trust and the Fund Administrator. Delivery instructions are as specified by the Custodian. The Custodian will supply the Subadviser daily with a cash availability report via access to the Custodian website, or by email or by facsimile and the Accounting Agent will provide a five-day cash projection. This will normally be done by email or, if email is unavailable, by another form of immediate written communication, so that the Subadviser will know the amount available for investment purposes.

FORM OF SUB-CERTIFICATION

To:

Re:

Subadviser’s Form N-CSR Certification for the [Name of Designated Series].

From:

[Name of Subadviser]

Representations in support of Investment Company Act Rule 30a-2 certifications of Form N-CSR.

[Name of Designated Series].

In connection with your certification responsibility under Rule 30a-2 and Sections 302 and 906 of the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act of 2002, I have reviewed the following information presented in the schedule of investments for the period ended [Date of Reporting Period] (the “Report”) which forms part of the N-CSR , as applicable, for the Trust.

Schedule of Investments

Our organization has designed, implemented and maintained internal controls and procedures, designed for the purpose of ensuring the accuracy and completeness of relevant portfolio trade data transmitted to those responsible for the preparation of the Schedule of Investments. As of the date of this certification there have been no material modifications to these internal controls and procedures.

In addition, our organization has:

Designed such internal controls and procedures to ensure that material information is made known to the appropriate groups responsible for servicing the above-mentioned mutual fund.

Designed and implemented controls which ensure that all transactions provided to the fund’s custodians/prime broker and accounting agent (“vendors”) have been delivered in a secure manner by authorized persons, and that access to the fund’s records maintained by the fund’s vendors is restricted to authorized persons of our firm or, if applicable, any third party administrator utilized by our firm. Such controls include review of the authorized persons at least annually and prompt communication of any changes to authorized persons to the fund’s vendors.

Evaluated the effectiveness of our internal controls and procedures, as of a date within 90 days prior to the date of this certification and we have concluded that such controls and procedures are effective.

In addition, to the best of my knowledge, there has been no fraud, whether or not material, that involves our organization’s management or other employees who have a significant role in our organization’s control and procedures as they relate to our duties as subadviser to the Designated Series.

I have read the draft of the Report which I understand to be current as of [Date of Reporting Period] and based on my knowledge, such draft of the Report, including the Fund Summary and Asset Allocations (as applicable), does not, with respect to the Designated Series, contain any untrue statement of a material fact or omit to state a material fact necessary to make the information contained therein, in light of the circumstances under which such information is presented, not misleading with respect to the period covered by such draft Report.

I have disclosed, based on my most recent evaluation, to the Designated Series’ Chief Accounting Officer:

All significant changes, deficiencies and material weakness, if any, in the design or operation of the Subadviser’s internal controls and procedures which could adversely affect the Registrant’s ability to record, process, summarize and report financial data with respect to the Designated Series in a timely fashion;

Any fraud, whether or not material, that involves the Subadviser’s management or other employees who have a significant role in the Subadviser’s internal controls and procedures for financial reporting.

I certify that to the best of my knowledge:

The Subadviser’s Portfolio Manager(s) has/have complied with the restrictions and reporting requirements of the Code of Ethics (the “Code”). The term Portfolio Manager is as defined in the Code.

The Subadviser has complied with the Prospectus and Statement of Additional Information of the Designated Series and the Policies and Procedures of the Designated Series as adopted by the Designated Series Board of Trustees.

I have no knowledge of any compliance violations except as disclosed in writing to the Virtus Compliance Department by me or by the Subadviser’s compliance administrator.

The Subadviser has complied with the rules and regulations of the 33 Act and 40 Act, and such other regulations as may apply to the extent those rules and regulations pertain to the responsibilities of the Subadviser with respect to the Designated Series as outlined above.

Since the submission of our most recent certification there have not been any divestments of securities of issuers that conduct or have direct investments in business operations in Iran or Sudan.

The subadviser has disclosed to the Adviser or the Designated Series any holdings required to be disclosed under the Iran Threat Reduction and Syria Human Rights Act of 2012, the Comprehensive Iran Sanctions, Accountability, and Divestment Act of 2010, the Iran Sanctions Act of 1996, as Amended and Executive Orders 13224, and 13382.

This certification relates solely to the Designated Series named above and may not be relied upon by any other fund or entity.

The Subadviser does not maintain the official books and records of the above Designated Series. The Subadviser’s records are based on its own portfolio management system, a record-keeping system that is not intended to serve as the Designated Series official accounting system. The Subadviser is not responsible for the preparation of the Report.
