If you tendered shares to Eaton Vance Senior Income Trust, a Massachusetts business trust registered under the Investment Company Act of 1940, as amended, as a closed-end management investment company (the “Fund”), in connection with the offer by the Fund to purchase for cash up to 1,753,886 (i.e., up to 10%) of its issued and outstanding common shares of beneficial interest, with par value of $.01 per share (the “Shares”), upon the terms and subject to the conditions set forth in the Offer to Purchase dated September 26, 2023 and the related Letter of Transmittal (which, together with any amendments or supplements thereto, collectively constitute the “Offer”), and you wish to withdraw your tender of all or any of your Shares, please fill out the attached Notice of Withdrawal. If your Shares are registered in the name of your broker, dealer, commercial bank, trust company or other nominee (“Nominee Holder”), please contact that Nominee Holder to withdraw your tendered Shares.

1. Withdrawal. If you have tendered your Shares pursuant to the Offer, you may withdraw your Shares previously tendered by completing, executing and sending the attached “Notice of Withdrawal” to any one of the addresses set forth on the first page of the Notice of Withdrawal. If your Shares are registered in the name of your Nominee Holder, please contact that Nominee Holder to withdraw your tendered Shares.

2. Delivery of Notice of Withdrawal. Equiniti Trust Company, LLC (the “Depositary”) must receive the Notice of Withdrawal prior to 5:00 p.m., Eastern Time, on October 25, 2023 (the “Expiration Date”), or if the Offer period is extended, by the close of regular trading of the New York Stock Exchange on the newly designated expiration date (the later of October 25, 2023 and the latest time or date to which the Offer is extended is hereafter called the “Expiration Date”). The method of delivery of any documents related to a withdrawal is at the option and risk of the withdrawing holder of Shares. Any documents related to a withdrawal will be deemed delivered only when actually received by the Depositary. If delivery is by mail, registered mail with return receipt requested, properly insured, is recommended. In all cases, sufficient time should be allowed to ensure timely delivery. If your Shares are registered in the name of your Nominee Holder, you may need to allow such Nominee Holder additional time to withdraw your tendered Shares on or before the Expiration Date. You should consult your Nominee Holder to determine if there is an earlier deadline by which you must inform such Nominee Holder of any decision to withdraw your tendered Shares.

3. Procedures and Signatures. The Notice of Withdrawal must specify the name of the person who tendered the Shares to be withdrawn and the number of Shares to be withdrawn and the name of the registered holder of Shares, if different from that of the person who tendered such Shares. The Notice of Withdrawal must specify the name and number of the account at the book-entry transfer facility to be credited with the withdrawn Shares (which must be the same name, number, and book-entry transfer facility from which the Shares were tendered), and must comply with the procedures of The Depository Trust Company. If this Notice of Withdrawal is signed by trustees, executors, administrators, guardians, agents, attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity, such persons should so indicate when signing, should indicate location of signing and must submit proper evidence satisfactory to the Fund of their authority to so act.
