The foregoing summary of the Declassification Proposal Letter does not purport to be complete and is qualified in its entirety by reference to the full text of the Declassification Proposal Letter, a copy of which is attached as Exhibit 2 and is incorporated by reference herein.

DECLASSIFICATION PROPOSAL LETTER

March 17, 2023

Via Electronic Mail and Courier

Ms. Diane Bono, Secretary

c/o Ecofin Sustainable and Social Impact Term Fund

6363 College Boulevard, Suite 100A

Overland Park, KS 66211

Re:Ecofin Sustainable and Social Impact Term Fund (the "Fund")

Dear Ms. Bono,

Saba Capital Management, L.P. (the "Proponent" or "Saba") is the investment adviser to Saba Capital Master Fund, Ltd., the owner of 402,002 shares of common stock, par value $0.001 per share of the Fund (the "Common Shares"), which has held continuously for more than one year shares representing a market value of $25,000 or more prior to and including the date hereof.

In accordance with Rule 14a-8 promulgated under the Securities and Exchange Act of 1934, as amended (the "Exchange Act"), the Proponent submits the following proposal for presentation to the Fund's stockholders at the Fund's 2024 annual meeting of stockholders, including any postponement or adjournment or special meeting held in lieu thereof (the "Meeting").

The Proponent's proposal pursuant to Rule 14a-8 of the Exchange Act (the "Proposal") is as follows:

PROPOSAL

RESOLVED, that the shareholders of Ecofin Sustainable and Social Impact Term Fund  (the "Fund") request that the Board of Directors of the Fund (the "Board") take all necessary steps in its power to declassify the Board so that all directors are elected on an annual basis starting at the next annual meeting of shareholders.  Such declassification shall be completed in a manner that does not affect the unexpired terms of the previously elected directors.

SUPPORTING STATEMENT

Saba believes that the annual election of all directors encourages board accountability to a company's shareholders which, in turn, boosts a board's performance thereby creating greater value for the shareholders it serves.  This view is shared by many, if not the overwhelming majority of, proxy advisory firms, institutional investors and large shareholders.  Companies that are attentive to their shareholder base and care about good governance have taken note, with ~90% of the S&P 500 and ~73% of the S&P 1,500 electing all of their board members annually.¹

^{____________________________________
1}Additionally, ~60% of the companies in the Russell 3,000 elect all their board members annually. See Matteo Tonello et al., Corporate Board Practices in the Russell 3000, S&P 500 and S&P Mid-Cap 400 (Nov. 2022) and Ernst & Young, EY Center for Board Matters: Corporate Governance by the Numbers (Mar. 2022).

Saba is committed to improving the corporate governance of the Fund for the benefit of all shareholders.  Currently, the Board is divided into three classes serving staggered three-year terms.  A classified board protects the incumbents and leads to entrenchment, which in turn limits accountability to shareholders and makes the board less responsive to shareholder concerns.  Empirical studies have found a statistically significant correlation between the presence of a classified board structure and a decline in firm value, with the effect even more pronounced where board classification is enshrined in a company's charter, as is the case with the Fund.²

Saba's proposal to declassify the Board is geared toward encouraging the Board to take positive steps towards the implementation of good governance and productive shareholder engagement, the totality of which, Saba believes, will allow the Fund to achieve its optimal valuation and unlock value for the Fund's shareholders.

For a greater voice in the Fund's corporate governance and to increase the accountability of the Board to shareholders, Saba urges you to vote FOR this proposal.

END OF PROPOSAL

Saba hereby represents that Saba has continuously and beneficially owned Common Shares with a market value of not less than $25,000 for at least one year prior to the date of the submission of Proposal, and intends to continue to hold the requisite number of Common Shares through the date of the Meeting. A letter from Saba's broker confirming the above ownership will be submitted under separate cover.

In accordance with Rule 14a-8(b)(1)(iii) of the Exchange Act, the Proponent represents that its representatives are able to meet with the Fund via teleconference no less than 10 calendar days, nor more than 30 calendar days, after submission of the Proposal. The Proponent will assume that the regular business hours of the Fund's principal executive offices, which are located in Kansas, are between 9:00 a.m. and 5:30 p.m. CDT, unless otherwise notified by the Fund. To that end, certain representatives of the Proponent are available to discuss the Proposal during the following business days and at the following times by teleconference:

• April 11, 2023, between 10:00 a.m. and 2:00 p.m. EST
• April 12, 2023, between 10:00 a.m. and 2:00 p.m. EST
• April 13, 2023, between 2:00 p.m. and 4:00 p.m. EST
