Introductory Note

On September 25, 2023 (the “Closing Date”), Otter Merger Sub, LLC (“Merger Sub”), a Delaware limited liability company and wholly owned direct, subsidiary of ONEOK, Inc., an Oklahoma corporation (“ONEOK”), completed its merger (the “Merger”) with and into Magellan Midstream Partners, L.P. a Delaware limited partnership (“Magellan”), as a result of which Magellan became a wholly owned, direct, subsidiary of ONEOK. The Merger was effected pursuant to the Agreement and Plan of Merger (the “Merger Agreement”), dated May 14, 2023, by and among ONEOK, Merger Sub and Magellan.

Item 1.02 Termination of a Material Definitive Agreement.

Credit Facility

In connection with the closing of the Merger, on September 25, 2023, Magellan, at the direction of ONEOK, terminated all outstanding lender commitments, including commitments of the lenders to issue letters of credit, under the Second Amended and Restated Credit Agreement, dated as of October 26, 2017, among Magellan, Wells Fargo Bank, National Association, as Administrative Agent and an Issuing Bank, JPMorgan Chase Bank, N.A., as Co-Syndication Agent and an Issuing Bank, and Suntrust Bank, as Co-Syndication Agent and an Issuing Bank, and the other lenders party thereto (as amended by that certain First Amendment to Second Amended and Restated Credit Agreement dated as of May 17, 2019 and that certain Second Amendment to Amended and Restated Credit Agreement dated as of November 8, 2022 and as otherwise amended prior to the date hereof, the “Credit Agreement”). In connection with the termination of the Credit Agreement, on September 25, 2023, all outstanding obligations for principal, interest and fees under the Credit Agreement were paid off in full.

Item 2.01 Completion of Acquisition or Disposition of Assets.

The disclosure set forth in the Introductory Note above is incorporated into this Item 2.01 by reference. As a result of the Merger, each unit of Magellan (the “Magellan Units”) issued and outstanding immediately prior to the time the Merger became effective (the “Effective Time”), was converted into the right to receive (i) 0.667 shares of ONEOK common stock, par value $0.01 (each whole share, the “ONEOK common stock”) and (ii) cash in the amount of $25.00. No fractional shares of ONEOK common stock will be issued in the Merger, and holders of Magellan Units will, instead, receive cash in lieu of fractional shares of ONEOK common stock, if any, as provided in the Merger Agreement.

In addition, at the Effective Time:

(i)

each Partnership RSU Award (as defined in the Merger Agreement), whether vested or unvested, that was outstanding immediately prior to the Effective Time was assumed by ONEOK and converted into a phantom unit award relating to a number of shares of ONEOK common stock equal to the number of Magellan Units subject to such Partnership RSU Award immediately prior to the Effective Time multiplied by the Equity Exchange Ratio (as defined in the Merger Agreement), rounded up or down to the nearest whole share of ONEOK common stock and otherwise subject to the same terms and conditions of such Partnership RSU Award; and

(ii)

each Partnership PSU Award (as defined in the Merger Agreement), whether vested or unvested, that was outstanding immediately prior to the Effective Time was assumed by ONEOK and converted into a phantom unit award relating to a number of shares of ONEOK common stock equal to the number of Magellan Units subject to such Partnership PSU Award immediately prior to the Effective Time, assuming achievement of the applicable performance based vesting condition at the maximum level, multiplied by the Equity Exchange Ratio, rounded up or down to the nearest whole share of ONEOK common stock and otherwise subject to the same terms and conditions of such Partnership PSU Award (other than the performance-based vesting conditions); provided, however, such assumed award or the relevant portion thereof will be paid to the holder thereof no later than March 15th of the year following the calendar year in which any substantial risk of forfeiture, within the meaning of Internal Revenue Code Section 409A, lapses with respect to such assumed award or the relevant portion thereof.

The issuance of shares of ONEOK common stock in connection with the Merger was registered under the Securities Act of 1933, as amended (the “Securities Act”), pursuant to ONEOK’s registration statement on Form S-4 (File No. 33-272758) (the “Registration Statement”), declared effective by the Securities Exchange Commission (the “SEC”) on July 24, 2023.

Upon the Partnership’s request, on September 25, 2023, the NYSE filed a notification of removal of listing on Form 25 to delist Magellan Units from the NYSE and the deregistration of the Magellan Units under Section 12(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Magellan Units ceased being traded prior to the opening of the market on September 25, 2023, and are no longer listed on NYSE.

In addition, Magellan intends to file with the SEC a Form 15 requesting that the reporting obligations of Magellan under Sections 13(a) and 15(d) of the Exchange Act be suspended.
