REASONS FOR OUR SOLICITATION

As one of the largest shareholders of Eaton Vance Senior Income Trust, Saba Capital has nominated a slate of three highly-qualified and independent Nominees (the Proposal).

We urge you to support our Proposal by voting the GOLD proxy card today, which we believe will help hold EVF accountable to drive value for shareholders.

______________________

PROPOSAL NO. 1
ELECTION OF TRUSTEES

The Board is currently composed of eleven (11) trustees, three (3) of whom we anticipate are up for election at the Annual Meeting by holders of Common Shares and Auction Preferred Shares, $0.01 par value per share, liquidation preference $25,000 per share (“APS”) of the Fund, voting together as a single class, as Class I trustees for a term expiring at the annual meeting of shareholders to be held in 2023 (the “2023 Annual Meeting”) and until their successors have been duly elected and qualified. We are seeking your support at the Annual Meeting to elect our three (3) Nominees in opposition to EVF’s Class I trustee nominees, to serve a three-year term expiring at the 2023 Annual Meeting. Our Nominees, if elected, will constitute a minority of the Board.

OUR NOMINEES

The following information sets forth the name, age, business address, present principal occupation, and employment and material occupations, positions, or offices for the past five (5) years of each of our Nominees. The nominations were made in a timely manner and in compliance with the applicable provisions of EVF’s governing instruments. The specific experience, qualifications, attributes and skills that led us to conclude that our Nominees should serve as trustees of EVF are set forth below.

Your vote to elect the Nominees will have the legal effect of replacing three incumbent trustees of EVF with our Nominees. The election of the Nominees requires the affirmative vote of a majority of the Fund’s shares outstanding and entitled to vote with respect to such nominee in order to be elected.

In the event that our Nominees are not elected to the Board at the Annual Meeting, Saba intends to consider all available options in the future with respect to EVF, including, without limitation, nominating trustee candidates or submitting shareholder proposals.

For additional information concerning our Nominees, see Appendix A – Information Concerning the Nominees and Participants (which is incorporated herein by reference).

WE URGE YOU TO VOTE FOR THE ELECTION OF OUR NOMINEES ON THE ENCLOSED GOLD PROXY CARD.

______________________

INFORMATION CONCERNING THE ANNUAL MEETING

VOTING AND PROXY PROCEDURES

EVF has set the close of business on [__] as the record date for determining shareholders entitled to notice of and to vote at the Annual Meeting (the “Record Date”). Shareholders of record at the close of business on the Record Date will be entitled to vote at the Annual Meeting. According to EVF, as of the Record Date, there were [__] Common Shares outstanding, and [__] APS shares outstanding.

Shareholders, including those who expect to attend the Annual Meeting, are urged to vote their shares today by following the instructions for Internet voting detailed on the enclosed GOLD proxy card, by calling the toll-free number contained therein, or by signing, dating and mailing the enclosed GOLD proxy card in the enclosed return envelope to Saba Capital Management, L.P., c/o InvestorCom, Inc., in the enclosed postage-paid envelope.

Authorized proxies will be voted at the Annual Meeting as marked and, in the absence of specific instructions, will be voted FOR the election of Saba’s Nominees, and in the discretion of the persons named as proxies on all other matters as may properly come before the Annual Meeting.

QUORUM

A quorum of shareholders is required to take action at the Annual Meeting. A quorum requires the presence, in person or by proxy, of a majority of the outstanding shares of EVF entitled to vote. Votes cast by proxy or in person at the Annual Meeting will be tabulated by the inspectors of election appointed for the Annual Meeting. The inspectors of election will determine whether or not a quorum is present at the Annual Meeting. The independent inspector of election will treat all shares that are voted, votes to withhold and shares represented by “broker non-votes”, if any, as present for purposes of establishing a quorum. However, broker non-votes and votes to withhold have no effect on the outcome of the trustee election, except, in the case of a contested election, they will reduce the likelihood of any nominee receiving the affirmative vote of a majority of eligible shares outstanding. Any adjournment of the Annual Meeting to permit further solicitation of proxies will require the affirmative vote of the holders of a majority of the shares present or by proxy at the session of the Annual Meeting to be adjourned.

If your shares are owned directly in your name with EVF’s transfer agent, you are considered a registered holder of those shares. If you are the beneficial owner of shares held by a broker or other custodian, you hold those shares in “street name” and are not a registered shareholder.

VOTES REQUIRED FOR APPROVAL

Election of Trustees – Pursuant to the Fund’s Amended and Restated By-Laws (the “By-Laws”), with respect to any election of trustees other than a contested election, a nominee must receive the affirmative vote of a plurality of votes cast at any meeting at which a quorum is present to be elected. A plurality means that the trustee nominee receiving the greatest number of votes will be elected. With respect to a contested election, a nominee must receive the affirmative vote of a majority of the Fund’s shares outstanding and entitled to vote with respect to such nominee in order to be elected. The By-Laws define a “contested election” as any election of trustees in which the number of persons validly nominated for election as trustees with respect to a given class or classes of Fund shares exceeds the number of trustees to be elected with respect to such class or classes. Because Saba has nominated the Nominees to be elected by the holders of the Common Shares and APS (voting together) at the upcoming Annual Meeting, the election of trustees is a contested election and, as such, each of the Nominees must receive the affirmative vote of a majority of the Fund’s shares outstanding and entitled to vote with respect to such Nominee to be elected at the Annual Meeting.

The information set forth above regarding the vote required to elect trustees is based on information contained in EVF’s proxy statement for the Annual Meeting. The incorporation of this information in this Proxy Statement should not be construed as an admission by us that such process and procedures are legal, valid or binding. 

Saba disputes the validity of the majority voting standard that EVF contends would apply in a contested election of trustees at the Annual Meeting. Saba believes that EVF’s amendments to the By-Laws to adopt the purported majority voting standard are unlawful, and that these amendments were not lawfully adopted by the Board. Saba has filed counterclaims in Massachusetts court challenging its legality.

On August 27, 2020, Saba Capital Master Fund, Ltd. filed a counterclaim in the Massachusetts Superior Court against EVF, Eaton Vance Senior Floating-Rate Trust, Eaton Vance Floating-Rate Income Trust, Eaton Vance Limited Duration Income Fund (collectively, the “Trusts”), Eaton Vance Management (“the Adviser”), and trustees Thomas E. Faust, Jr., Mark R. Fetting, Cynthia E. Frost, George J. Gorman, Valerie A. Mosley, William H. Park, Helen Frame Peters, Keith Quinton, Marcus L. Smith, Susan J. Sutherland, and Scott E. Wennerholm in their capacity as trustees (collectively, the “Trustees”) seeking, among other things, declaratory relief on the basis that the Trustees adopted unlawful amendments to the By-Laws, including an amendment purportedly changing the threshold for replacing trustees from a plurality of shares actually voted to a majority of all outstanding shares in contested elections, and publicly filed the amended By-Laws with the SEC only after Saba provided notice to EVF that it intended to nominate a slate of three individuals for election to the Board at the Annual Meeting. 

BROKER NON-VOTES

Broker-dealer firms holding shares of EVF in “street name” for the benefit of their customers and clients will request the instructions of such customers and clients on how to vote their shares on the proposals before the Annual Meeting. Under the rules of the New York Stock Exchange (“NYSE”), if you do not give specific voting instructions to your broker, generally your broker will have discretion to vote your shares on routine matters but will not have discretion to vote your shares on non-routine matters. When the broker exercises its discretion to vote on routine matters in the absence of voting instructions from you, a “broker non-vote” occurs with respect to the non-routine matters since the broker will not have discretion to vote on such non-routine matters. Given the contested nature of the Proposal, your broker may not vote your shares on such Proposal at the Annual Meeting. Additional information regarding when a “broker non-vote” occurs with respect to non-routine matters may be found in EVF’s proxy statement. We urge you to instruct your broker or other nominee to vote your shares for the GOLD proxy card so that your votes may be counted.

Broker-dealers who are not members of the NYSE may be subject to other rules, which may or may not permit them to vote your shares without instruction. We urge you to provide instructions to your broker or nominee to vote your shares for the GOLD proxy card so that your votes may be counted. For purposes of determining the approval of the Proposal to elect trustees of EVF, broker non-votes will have no effect.

DISCRETIONARY VOTING

Shares held in “street name” and held of record by banks, brokers or nominees may not be voted by such banks, brokers or nominees unless the beneficial owners of such shares provide them with instructions on how to vote. In the event that there are no routine matters to be voted on, there will be no broker non-votes and shares held in street name for which voting instructions have not been received will be treated identically to shares held by a record holder who does not appear at the meeting in person or by proxy, i.e., the holder of those shares is not present for purposes of a quorum. A decision to withhold your vote (or a direction to your broker-dealer to do so) will be counted towards quorum but will have no effect on the outcome of the trustee election, except, in the case of a contested election, it will reduce the likelihood of any nominee receiving the affirmative vote of a majority of eligible shares outstanding.

REVOCATION OF PROXIES

Shareholders of EVF may revoke their proxies at any time prior to exercise by attending the Annual Meeting and voting in person (although attendance at the Annual Meeting will not in and of itself constitute revocation of a proxy), by delivering a later-dated proxy by Internet, by telephone or by mail, or by delivering a written notice of revocation. The delivery of a later-dated proxy which is properly completed will constitute a revocation of any earlier proxy. The revocation may be delivered either to Saba in care of InvestorCom, Inc. (“InvestorCom”) at the address set forth on the back cover of the Proxy Statement or to EVF’s Secretary c/o Eaton Vance Senior Income Trust, Two International Place, Boston, Massachusetts 02110, or to any other address provided by EVF. Although a revocation is effective if delivered to EVF, Saba requests that either the original or photostatic copies of all revocations be mailed to Saba Capital Management, L.P., c/o InvestorCom, 19 Old Kings Highway S., Suite 210, Darien, CT 06820, so that Saba will be aware of all revocations and can more accurately determine if and when proxies have been received from the holders of record on the record date of a majority of the outstanding shares. If you hold your shares in street name, please check your voting instruction card or contact your bank, broker or nominee for instructions on how to change or revoke your vote. Additionally, InvestorCom may use this information to contact shareholders who have revoked their proxies in order to solicit later-dated proxies for the election of the Nominees as described herein.

SOLICITATION OF PROXIES

The solicitation of proxies pursuant to the Proxy Statement is being made by Saba. Proxies may be solicited by mail, facsimile, telephone, Internet, in person and by advertisements.

Saba has entered into an agreement with InvestorCom for solicitation and advisory services in connection with this solicitation, for which InvestorCom will receive a fee not to exceed $25,000, together with reimbursement for its reasonable out-of-pocket expenses, and will be indemnified against certain liabilities and expenses, including certain liabilities under the federal securities laws. InvestorCom will solicit proxies from individuals, brokers, banks, bank nominees and other institutional holders. Saba has requested banks, brokerage houses and other custodians, nominees and fiduciaries to forward all solicitation materials to the beneficial owners of the shares they hold of record. It is anticipated that InvestorCom will employ up to 25 persons to solicit EVF’s shareholders for the Annual Meeting.

The entire expense of soliciting proxies is being borne by Saba. Because Saba believes that EVF’s shareholders will benefit from this solicitation, Saba intends to seek reimbursement from EVF, to the fullest extent permitted by law, of all expenses it incurs in connection with this solicitation. Saba does not intend to submit the question of such reimbursement to a vote of security holders of EVF unless otherwise required by law. Costs of this solicitation of proxies are currently estimated to be approximately $[__]. We estimate that through the date hereof, its expenses in connection with this solicitation are approximately $[__].

SHAREHOLDER PROPOSALS

According to EVF’s proxy statement for the Annual Meeting, to be considered for presentation at EVF’s 2021 Annual Meeting of Shareholders, a shareholder proposal submitted pursuant to Rule 14a-8 under the Securities Exchange Act of 1934 must be received at the Fund’s principal office c/o the Secretary of the Fund on or before [__], 2021. Written notice of a shareholder proposal submitted outside of the processes of Rule 14a-8 must be delivered to the Fund’s principal office c/o the Secretary of the Fund no later than the close of business on [__], 2021 and no earlier than [__], 2021. In order to be included in the Fund’s proxy statement and form of proxy, a shareholder proposal must comply with all applicable legal requirements. Timely submission of a proposal does not guarantee that such proposal will be included.

The information set forth above regarding the procedures for submitting shareholder nominations and proposals for consideration at the 2021 Annual Meeting is based on information contained in EVF’s proxy statement for the Annual Meeting. The incorporation of this information in the Proxy Statement should not be construed as an admission by us that such procedures are legal, valid or binding.

______________________

OTHER MATTERS AND ADDITIONAL INFORMATION

Saba is unaware of any other matters to be considered at the Annual Meeting. However, should other matters, which Saba is not aware of a reasonable time before this solicitation, be brought before the Annual Meeting, the persons named as proxies on the enclosed GOLD proxy card will vote on such matters in their discretion.

We are asking you to vote FOR the election of our Nominees. The enclosed GOLD proxy card may only be voted for our Nominees and does not confer voting power with respect to EVF’s nominees.

Saba has omitted from this proxy statement certain disclosure required by applicable law that is already included in EVF’s proxy statement. This disclosure includes, among other things, biographical information on EVF’s trustees and executive officers, the dollar range of shares owned by trustees of EVF and information on committees of the Board. Shareholders should refer to EVF’s proxy statement in order to review this disclosure.

According to EVF’s proxy statement, EVF’s investment adviser and administrator is Eaton Vance Management (the “Adviser”), located at Two International Place, Boston, Massachusetts 02110. The Adviser is a subsidiary of Eaton Vance Corp., an investment management firm.

The information concerning EVF contained in this Proxy Statement and the appendices attached hereto has been taken from, or is based upon, publicly available information.

APPENDIX A

INFORMATION CONCERNING THE NOMINEES AND PARTICIPANTS

Saba has nominated three (3) highly-qualified individuals for election as trustees at the Annual Meeting: Stephen G. Flanagan, Frederic Gabriel and Christopher A. Klepps.

This proxy solicitation is being made by (i) Saba Capital Management, L.P. (“Saba Capital”); (ii) Saba Capital Master Fund, Ltd. (“SCMF”); (iii) Saba II AIV, L.P., (“AIV”); (iv) Saba Capital Master Fund III, L.P. (“SCMF3”); (v) Saba Capital Carry Neutral Tail Hedge Master Fund Ltd. (“CNTH”); (vi) Saba Capital R Fund, Ltd. (“R Fund”); (vii) Saba Capital CEF Opportunities 1, Ltd. (“CEF 1”); (viii) Saba Capital CEF Opportunities 3, Ltd. (“CEF 3”); (ix) Saba Capital Special Opportunities Fund, Ltd. (“SSOF”); (x) certain separately managed accounts managed by Saba Capital (together with SCMF, AIV, SCMF3, CNTH, R Fund, CEF 1, CEF 3 and SSOF, the “Saba Entities”); (xi) Boaz R. Weinstein, principal of Saba Capital (“Mr. Weinstein,” and together with Saba Capital and the Saba Entities, “Saba”); and (xii) the Nominees. The entities and individuals listed in this paragraph may each be deemed a “Participant” and, collectively, the “Participants.”

As of the close of business on [__], the Participants may be deemed to “beneficially own” (within the meaning of Rule 13d-3 or Rule 16a-1 under the Exchange Act for the purposes of this Appendix A), in the aggregate, 7,864,642 Common Shares, par value $0.01 per share, of EVF (the “Common Shares”), representing approximately 21% of EVF’s outstanding Common Shares. The percentages used herein are based upon [__] Common Shares outstanding as of the Record Date for the Annual Meeting, [__]. Saba Capital may be deemed to beneficially own 7,864,642 Common Shares.

As of the date of this Proxy Statement, none of the Nominees beneficially own any Common Shares, nor do any of the Nominees beneficially own any other securities of EVF and have not engaged in any transactions in securities of EVF during the past two (2) years. None of the Nominees nor any of their Immediate Family Members owns beneficially or of record any class of securities in (i) EVF’s investment adviser, principal underwriter or Sponsoring Insurance Company; or (ii) any person (other than a registered investment company) directly or indirectly controlling, controlled by, or under common control with EVF’s investment adviser, principal underwriter, or Sponsoring Insurance Company. Each of our Nominees specifically disclaims beneficial ownership of the securities that he does not directly own. For information regarding purchases and sales of securities of EVF during the past two (2) years by certain members of Saba, see Appendix B – Transactions in Securities of EVF During the Past Two Years (which is incorporated herein by reference).

Since the beginning of EVF’s last two completed fiscal years, no officer of an investment adviser, principal underwriter, or Sponsoring Insurance Company of EVF, or of a person directly or indirectly controlling, controlled by, or under common control thereby, serves, or has served, on the board of directors of a company of which any of the Nominees is an officer.

None of the Nominees nor any of their Immediate Family Members (as such term is defined in the Investment Company Act) has or has had any direct or indirect interest, the value of which exceeded or is to exceed $120,000, during the past five years, in (i) EVF’s investment adviser, principal underwriter or Sponsoring Insurance Company; or (ii) any person (other than a registered investment company) directly or indirectly controlling, controlled by, or under common control with EVF’s investment adviser, principal underwriter, or Sponsoring Insurance Company. In addition, none of the Nominees or any of their Immediate Family Members has, or has had since the beginning of EVF’s last two completed fiscal years, or has currently proposed, any direct or indirect relationship, in which the amount involved exceeds $120,000, with any of the persons specified in paragraphs (b)(8)(i) through (b)(8)(viii) of Item 22 of Schedule 14A.

Saba believes that each Nominee presently is, and if elected as a trustee of EVF, will be, an “independent director” within the meaning of (i) applicable New York Stock Exchange listing standards applicable to board composition, including Rule 303A.02, and (ii) Section 301 of the Sarbanes-Oxley Act of 2002, as amended. Notwithstanding the foregoing, no trustee of a NYSE listed company qualifies as “independent” under the NYSE listing standards unless the board of trustees affirmatively determines that such trustee is independent under such standards. Accordingly, if the Nominees are elected, the determination of the Nominees’ independence under the NYSE listing standards ultimately rests with the judgment and discretion of the Board. No Nominee is a member of EVF’s compensation, nominating or audit committees that is not independent under any such committee’s applicable independence standards.

Each of the Nominees has entered into a nominee agreement pursuant to which Saba has agreed to pay the costs of soliciting proxies in connection with the Annual Meeting and to defend and indemnify such Nominees against, and with respect to, any losses that may be incurred by them in connection with their nomination as candidates for election to the Board and the solicitation of proxies in support of their election. Each of the nominee agreements provide customary confidentiality obligations and other restrictions, on the part of the Nominees, including that such Nominees will not transact in securities of EVF without the prior consent of Saba Capital. Pursuant to the nominee agreements and in connection with their nominations, the Nominees may receive a nominal advancement not to exceed $2,500, the purposes of which is to cover the reimbursement of fees in connection with each such Nominee’s nomination, subject to termination for cause. The Nominees will not receive any compensation from Saba for their services as trustees of EVF if elected for any other reason. If elected, the Nominees will be entitled to such compensation from EVF as is consistent with EVF’s practices for services of trustees who are not “interested persons” of EVF.

The Participants entered into a Joint Filing and Solicitation Agreement (the “Joint Filing and Solicitation Agreement”) in which, among other things, (i) the Participants agree to the joint filing on behalf of each of them of statements on Schedule 13D, and any amendments thereto, with respect to the Common Shares, (ii) the Participants agree to solicit proxies or written consents in favor of the election of the Nominees to the Board at the Annual Meeting, (iii) each of the Nominees agree to provide Saba advance notice prior to effecting any purchase, sale, acquisition or disposal of any securities of the Fund of which he has, or would have, direct or indirect beneficial ownership, (iv) each of the Nominees agree that he shall not undertake or effect any purchase, sale, acquisition or disposal of any securities of the Fund without the prior consent of Saba, and (v) Saba agrees to pay directly all pre-approved expenses in connection with the solicitation.

Other than as stated herein, there are no arrangements or understandings among members of Saba and any of the Nominees or any other person or persons pursuant to which the nomination of our Nominees described herein is to be made, other than the consent by each Nominee to be named in this Proxy Statement and to serve as a trustee of EVF, if elected as such at the Annual Meeting. None of our Nominees is a party adverse to EVF, or any of its subsidiaries, or has a material interest adverse to EVF, or any of its subsidiaries, in any material pending legal proceeding.

We do not expect that any of our Nominees will be unable to stand for election, but, in the event that any Nominee is unable to serve or, for good cause, will not serve, the shares represented by the enclosed GOLD proxy card will be voted for substitute nominee(s), to the extent this is not prohibited under the Bylaws and applicable law. In addition, we reserve the right to nominate substitute person(s) if EVF makes or announces any changes to the Bylaws or takes or announces any other action that has, or if consummated would have, the effect of disqualifying any Nominee, to the extent this is not prohibited under the Bylaws and applicable law. In any such case, the shares represented by the enclosed GOLD proxy card will be voted for such substitute nominee(s). We reserve the right to nominate additional person(s), to the extent this is not prohibited under the Bylaws and applicable law, if EVF increases the size of the Board above its existing size or increases the number of trustees whose terms expire at the Annual Meeting. Additional nominations made pursuant to the preceding sentence are without prejudice to the position of Saba that any attempt to increase the size of the current Board or to change the classifications of the Board would constitute an unlawful manipulation of EVF’s corporate machinery.

The principal business of Mr. Weinstein is investment management and serving as the Managing Member of Saba Capital Management GP, LLC, a Delaware limited liability company by virtue of its status as the general partner to Saba Capital. The principal business of Saba Capital is to serve as investment manager to various funds that directly hold the Common Shares reported in the aggregate herein. The principal business of the Saba Entities is to invest in securities. Information on the principal occupation of each of the Nominees is set forth in Proposal 1: Election Of Trustees.

The principal business address of each of Mr. Weinstein and Saba Capital is 405 Lexington Avenue, 58th Floor, New York, New York 10174. The principal business address of each of Messrs. Flanagan, Gabriel and Klepps is c/o Olshan Frome Wolosky LLP, 1325 Avenue of the Americas, New York, NY 10019, Attn: Adam Finerman.

Each of the Nominees is a citizen of the United States of America.

The relevant information provided above has been furnished to Saba by the Nominees.

Unless otherwise noted as shares held in record name by the Saba Entities, the Common Shares held by the Saba Entities are held in commingled margin accounts, which may extend margin credit to such parties from time to time, subject to applicable federal margin regulations, stock exchange rules and credit policies. In such instances, the positions held in the margin account are pledged as collateral security for the repayment of debit balances in the account. The margin accounts bear interest at a rate based upon the broker’s call rate from time to time in effect. Because other securities are held in the margin accounts, it is not possible to determine the amounts, if any, of margin used to purchase the Common Shares reported herein since margin may have been attributed to such other securities and since margin used is not disclosed on an individual per-security basis.

Except as set forth in this Proxy Statement (including the Appendices hereto), (i) during the past 10 years, no Participant in this solicitation has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors); (ii) no Participant and no associate or “Immediate Family Member” (as defined in Item 22 of Schedule 14A under the Exchange Act (“Item 22”)) of any Participant, is a record owner or direct or indirect beneficial owner of any securities of EVF, any parent or subsidiary of EVF, any investment adviser, principal underwriter, or “Sponsoring Insurance Company” (as defined in Item 22) of EVF, or in any registered investment companies overseen or to be overseen by the Participant within the same “Family of Investment Companies” (as defined in Item 22) that directly or indirectly controls, is controlled by or is under common control with an investment adviser, principal underwriter, or Sponsoring Insurance, or affiliated person of EVF; (iii) no Participant in this solicitation owns any securities of EVF which are owned of record but not beneficially; (iv) no Participant in this solicitation has purchased or sold any securities of EVF or EVF’s investment adviser during the past two years, nor from either entity’s “Parents” or “Subsidiaries” (as defined in Item 22); (v) no Participant has any “family relationship” for the purposes of Item 22 whereby a family member is an “Officer” (as defined in Item 22 ), director (or person nominated to become an Officer or director), employee, partner, or copartner of EVF, EVF’s investment adviser and/or a principal underwriter of any of the foregoing, or any Subsidiary or other potential affiliate of any of the foregoing; (vi) no part of the purchase price or market value of the securities of EVF owned by any Participant in this solicitation is represented by funds borrowed or otherwise obtained for the purpose of acquiring or holding such securities; (vii) no Participant in this solicitation is, or within the past year was, a party to any contract, arrangements or understandings with any person with respect to any securities of EVF, including, but not limited to, joint ventures, loan or option arrangements, puts or calls, guarantees against loss or guarantees of profit, division of losses or profits, or the giving or withholding of proxies;
