EXHIBIT 4

Standstill Agreement

This Agreement is entered into as of August 3, 2022 (this "Agreement" (including the exhibits hereto)), by and among Saba Capital Management, L.P. ("Saba") and Salient Capital Advisors, LLC (the "Advisor" and, together with Saba, the "Parties" and individually a "Party").

Whereas, Salient Midstream & MLP Fund (the "Fund") has announced that its Board of Trustees (the "Board") has approved a reorganization of the Fund (the "Reorganization") with and into Salient MLP & Energy Infrastructure Fund, a series of Salient MF Trust (the "Surviving Fund", and together with the Fund, the "Funds"), and the Advisor is the advisor of both the Fund and the Surviving Fund.

Whereas, the Advisor expects the Reorganization to be completed by September 30, 2022;

Whereas, the board of trustees of Salient MF Trust (together with the Board, the "boards") has approved a reorganization transaction for Salient MF Trust on behalf of the Surviving Fund (the "Surviving Fund Transaction") in connection with a sale by the parent company of the Advisor and certain of its Affiliates of substantially all of their respective assets in a transaction with Westwood Holdings Group, Inc., and has approved the solicitation of Surviving Fund shareholders to approve the Surviving Fund Transaction; and

Whereas, as of the close of business on the date hereof, Saba may be deemed to be the beneficial owner (as such term is used in Rule 13d-3 under the Securities Exchange Act of 1934, as amended (the "Exchange Act")) of, in the aggregate, 4,216,057 common shares of beneficial interest of the Fund, $0.01 par value (the "Common Shares"), which includes Common Shares held by one or more private funds and accounts managed by Saba (the "Saba Private Funds") and one or more public funds registered under the Investment Company Act of 1940 (the "Saba RICs"). For the avoidance of doubt, the Saba RICs are not a party to, are not restricted by and are not governed by, the terms of this Agreement.

Now, Therefore, in consideration of the mutual covenants and agreements contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties hereto hereby agree as follows:

(a) The Advisor represents and warrants that the Fund has declared a special distribution in the aggregate amount of $300,000 expected to be paid after the Reorganization is approved by Fund shareholders and before the consummation of the Reorganization (the "Special Distribution"), such Special Distribution to be paid no later than the earlier of (i) the next scheduled distribution and (ii) September 30, 2022.

Fund Press Release

SALIENT MIDSTREAM & MLP FUND ANNOUNCES THIRD QUARTER 2022 DISTRIBUTION AND ACCOMPANYING SPECIAL DISTRIBUTION, NET ASSET VALUE AS OF JULY 31, 2022 AND RECORD DATE FOR REORGANIZATION

HOUSTON, TX - August , 2022 - Salient Midstream & MLP Fund (the "Fund") (NYSE: SMM) today announced a distribution of $0.0875 per share for the third quarter ending August 31, 2022. The Fund also announced a special distribution of $0.0169 per share, for an aggregate amount of $300,000, in connection with the Fund's potential reorganization and an anticipated payment by the Advisor. These distributions will be payable on August 30, 2022 to common shareholders of record on August 18, 2022. It is anticipated that these distributions will be a combination of return of capital and ordinary income for tax purposes. The final tax status of the distribution may differ substantially from this preliminary information, and the final determination of such amount will be made after the end of the fiscal year.

In addition, the Fund announced that August 10 will be the record date for determining shareholders entitled to vote on the reorganization of the Fund into Salient MLP & Energy Infrastructure Fund ("SMAPX"), an open-end fund that is a series of Salient MF Trust and has a similar investment strategy. The Fund and SMAPX are both managed by Salient Capital Advisors, LLC. As previously announced, on June 28, 2022, after consideration of a variety of factors and alternatives, the Board of Trustees determined that it would be in the best interest of shareholders to reorganize SMM into SMAPX. The proposal to reorganize SMM into SMAPX will require the approval of SMM shareholders.

At the close of business on July 31, 2022, the Fund's total assets were $215.7 million and the Net Asset Value (NAV) per share was $8.89.¹

The Fund's quarterly distributions per share over the past year are shown below:²

$0.0875		August 30, 2022	August 17, 2022	August 18, 2022

¹ Past performance is not indicative of future results. Current performance may be higher or lower than the data shown. The data shown are unaudited. Returns do not reflect the deduction of taxes that shareholders may have to pay on Fund distributions or upon the sale of Fund shares.

² The amount of distributions may vary depending on a number of factors. As portfolio and market conditions change, the rate of distributions on Fund common shares could change. A portion of the Fund's returns may be comprised of ordinary income, return of capital and net realized capital gains. The Fund will determine the tax characteristics of all Fund distributions after the end of the calendar year and will provide shareholders such information at that time.

Since the Fund's inception, the portfolio management team has focused on generating top-tier total returns rather than focusing on maximizing distributions. The Fund's performance over multiple time periods versus its peers is provided in the table below along with a ranking of SMM vs. peers.

All investments are subject to investment risk, including loss of principal invested. The chart above in no way represents performance as it relates to SMAPX.

Since inception in 2012, SMM is the second best performing closed-end fund on market price and the third best on NAV in the peer group of eleven funds.

SMM's inception to date (ITD) annualized total return (based on market price) of -1.4% has outperformed the RIC Average of -4.5% and C-Corp average of -3.7%. Likewise, on a NAV basis, SMM's ITD return of -0.8% compares favorably to the -2.8% return for the peer group of RIC Funds and -2.1% for C-Corp Funds.

July Market Commentary

Energy infrastructure equities rebounded strongly in July after a difficult June. The energy infrastructure industry was up 10.9% as measured by the Alerian Midstream Energy Select Index (AMEI).³ The strong market rebound was driven by multiple factors with many analysts citing "peak inflation" expectations as a proximate cause for the rally. We believe that healthy second quarter earnings expectations combined with dividend payments (about 65% of the AMEI goes ex-dividend in late July and early August ⁴) also played a role in the energy infrastructure industry's monthly performance. For the balance of 2022, we remain positive on the industry as 1) free cash flow after dividends is growing at a healthy pace, 2) hydrocarbon volumes are growing as drilling activity improves and 3) capital allocation remains mostly focused on returning excess cash to investors through buybacks and potential dividend increases.⁵

⁵ Free cash flow after distributions represents the cash a company generates after accounting for cash outflows to support operations and maintain its capital assets. Hydrocarbon a compound of hydrogen and carbon, such as any of those which are the chief components of petroleum and natural gas. Share buybacks are when a company buys its own outstanding shares to reduce the number of shares available on the open market.

Crude oil as measured by the West Texas Intermediate (WTI) benchmark was down 6.8% for the month of July but is now up 31.1% for the year.⁴ Recent crude oil price weakness is in part driven by fears that a recession could negatively impact crude oil demand and thus weigh on prices. During the past two recessions, crude oil demand declined, and we think investors have priced in some of those expectations today. Looking at past recessions, demand doesn't always decline - in both the 2001 and 1991 recessions global crude oil demand actually continued to grow.⁴ We will look to additional data points in coming months to determine whether demand is being impacted, however, based on data in hand it still appears that demand continues to outstrip supply and that global inventories are continuing to decline at this time.⁴ Longer term, we view crude oil prices in the $70-$80 range as being positive for investment in the American energy industry. Commodity analysts continue to see a tight supply environment for both crude oil and natural gas in 2022 and potentially in 2023. We believe that current prices are sufficient to lead to U.S. volume growth this year. The promise of these incremental volumes should be supportive of midstream companies.
