STANDSTILL AGREEMENT

This Standstill Agreement (the “Agreement”) is made and entered into effective as of 5:00 p.m., Eastern time, on the 18th day of July 2019 by and between Massachusetts Financial Services Company (“MFS”), having its principal place of business at 111 Huntington Avenue, Boston, MA 02199 and Saba Capital Management, L.P., having its principal place of business at 405 Lexington Avenue, 58^th Floor, New York, NY 10174 (together with Boaz R.

WHEREAS, on January 23, 2019, Saba and Boaz R.

WHEREAS, the parties to this Agreement wish to memorialize and agree to certain terms and conditions regarding the Proposal;

NOW, THEREFORE, in consideration of the mutual promises and covenants contained in this Agreement, and other good and valuable consideration, the parties agree as follows:

1. Recommendation to Trustees. On or before July 19, 2019, MFS shall recommend that the Board of Trustees of the Trust (the “Board”) approve the termination and liquidation of the Trust.

2. Saba’s Obligations. Subject to Board approval, upon public announcement by the Trust of its intention to liquidate the Trust (the “Announcement”):

Saba hereby agrees to vote at the Trust’s 2019 annual shareholder meeting FOR the slate of Trustees nominated by the Board and to vote against any shareholder proposals not recommended for shareholder approval by the Board;

Saba shall, for a period commencing on the date of the Announcement and through the date that is the earlier of (x) the day after the date of the completion of the last annual meeting (or special meeting in lieu thereof) held during calendar 2020, including any adjournments or postponements thereof, of an MFS Closed-End Fund listed on Appendix A hereto (including without limitation with respect to the Trust’s annual shareholder meeting to be held in calendar 2019), and (y) the date that is 60 days prior to the last date that a shareholder proposal pursuant to Rule 14a-8 under the Securities Exchange Act of 1934 (the “Exchange Act”) or a Trustee nomination is permitted to be submitted to the Trust for the Trust’s annual meeting of shareholders to be held during calendar 2021 (such period, the “Term Period”), (i) refrain from directly or indirectly making, supporting or encouraging any shareholder proposals concerning any MFS Closed-End Fund; (ii) vote in accordance with the Board’s recommendations on nominees for election as Trustees of the MFS Closed-End Funds; (iii) vote in accordance with the Board’s recommendations on any other matters affecting any MFS Closed-End Fund; (iv) refrain from directly or indirectly soliciting or encouraging others to vote against the Board’s recommendations on any matters affecting any MFS Closed-End Fund; (v) refrain from proposing any nominees for election to the Board of any MFS Closed-End Fund; (vi) refrain from directly or indirectly proposing, or making any filing with respect to, any form of business combination, restructuring, recapitalization, dissolution or similar transaction involving any MFS Closed-End Fund, including, without limitation, a merger, tender or exchange offer, open-ending, share repurchase or liquidation of any MFS Closed-End Fund’s assets; (vii) refrain from granting a proxy with respect to shares of any MFS Closed-End Fund other than to officers of, or other persons named as proxies by, such MFS Closed-End Fund; (viii) refrain from executing any written consent with respect to the shares of any MFS Closed-End Fund other than as may be solicited by such MFS Closed-End Fund; (ix) refrain from depositing any securities of an MFS Closed-End Fund in any voting trust or subjecting any securities of any MFS Closed-End Fund to any arrangement or agreement with respect to the voting securities of an MFS Closed-End Fund, including, without limitation, through lending any securities of an MFS Closed-End Fund to any person or entity; (x) refrain from knowingly joining or participating in any “group” (within the meaning of Section 13(d)(3) of the Exchange Act and Rule 13d-5(b)(1) thereunder) concerning any MFS Closed-End Fund; (xi) refrain from seeking the removal of any member of the Board of any MFS Closed-End Fund; (xii) refrain from seeking control or influence over the management or policies of any MFS Closed-End Fund; (xiii) refrain from making a request for a shareholder list or other books or records of an MFS Closed-End Fund under Massachusetts law or any other statutory or regulatory provision; (xiv) refrain from publicly disclosing any intention, plan, proposal or arrangement or other matter inconsistent with its obligations under this subparagraph 2(b) (except as required under Schedule 13D); and (xv) refrain from requesting, directly or indirectly, any amendment or waiver of any provision of this subparagraph 2(b) (including this sentence).

Nothing in this Agreement shall be deemed to prohibit Saba and its affiliates from communicating privately with the trustees, officers, and advisors of any MFS Closed-End Fund (including their adviser) so long as such private communications would not be reasonably determined to trigger public disclosure obligations for any party.

Notwithstanding anything herein to the contrary, the covenants set forth in this Section 2 shall not be deemed to (i) include or (ii) prevent the voting of, any Common Shares held by any open-ended investment company registered under the Investment Company Act of 1940 (the “1940 Act”) advised or sub-advised by Saba (the “ETF”). The shares of the ETF shall be voted proportionately in accordance with the method prescribed in the second clause of Section 12(d)(1)(E)(iii)(aa) of the 1940 Act (“Mirror Voting”) and in accordance with the proxy voting policy of the ETF.

3. Termination

Notwithstanding anything herein to the contrary, if (i) the Board fails to approve the liquidation of the Trust and the Announcement is not made on or before July 26, 2019 or (ii) the liquidation of the Trust is not completed on or before October 31, 2019, this Agreement shall terminate and be of no further force or effect.

Otherwise, this Agreement shall remain in full force and effect until the earlier of:

the end of the Term Period; and

ii.

such other date as may be established by mutual written agreement of the Trust and Saba.

4. No Disparagement. During the Term Period, each party hereto shall refrain from directly or indirectly disparaging, impugning, or taking any action reasonably likely to damage the reputation of the other party, their members, partners, directors, officers, employees or affiliates, or any members of the Board with respect any matters affecting any MFS Closed-End Fund. The foregoing shall not apply to any compelled testimony or production of information, either by legal process, subpoena, or as part of a response to a request for information from any governmental authority with jurisdiction over the party from whom information is sought.

5. Third Party Beneficiaries. The parties agree that the MFS Closed-End Funds are intended as third party beneficiaries of this Agreement, and that any MFS Closed-End Fund is entitled to rely on and may enforce the terms and provisions hereof directly as if it were a party hereto.

6. No Assignment. This Agreement shall be binding upon the parties and their respective legal successors and permitted assigns. Neither party may assign this Agreement without the prior written consent of the other party and any such attempted assignment shall be void.

7. Applicable Law. The validity of this Agreement, the construction and enforcement of its terms, and the interpretations of the rights and duties of the parties shall be governed by the laws of the State of New York, without regard to conflicts of law rules. The parties hereto agree that the state and federal courts of the State of New York, county of New York shall be the proper forums for any legal controversy arising in connection with this Agreement, and the parties hereby irrevocably and unconditionally consent to the exclusive jurisdiction of such courts for such purposes.

8. Waiver of Jury Trial. To the fullest extent permitted by applicable law, each of the parties hereto hereby irrevocably waives any and all right to trial by jury in any suit, action or proceeding arising under this Agreement.

9. Injunctive Relief: Each party acknowledges that a breach of its obligations under this Agreement may result in irreparable harm to the other party for which monetary damages may not be sufficient. Each party hereto agrees that, in the event of a breach or threatened breach by the other party of its obligations under this Agreement, the non-breaching party shall be entitled, in addition to its other rights and remedies hereunder or at law, to seek injunctive or other equitable relief, and such further relief as may be proper from a court of competent jurisdiction, including specific performance of the obligations set forth in Paragraph 2 of this Agreement.

10. Modification. No modification, amendment, supplement to or waiver of this Agreement of any of its provisions shall be binding upon the parties hereto unless made in writing and duly signed by all parties.

11. Invalidity. In the event that any one or more of the provisions of this Agreement shall for any reason be held to be invalid, illegal, or unenforceable, the remaining provisions of this Agreement shall be unimpaired, and the invalid, illegal or unenforceable provision shall be replaced by a mutually acceptable provision, which being valid, legal and enforceable, comes closest to the economic effect and intent of the parties underlying the invalid, illegal or unenforceable provision.

12. No Waiver. A waiver of a breach or default under this Agreement shall not be a waiver of any other or subsequent breach or default. The failure or delay in enforcing compliance with any term or condition of this Agreement shall not constitute a waiver of such term or condition unless such term or condition is expressly waived in writing.

13. Counterparts. This Agreement may be executed in counterparts transmitted by facsimile or other electronic means, and each counterpart shall have the effect of an original.

14. Confidentiality/Public Disclosure.
