As described in Item 4, ET entered into the Support Agreement (as defined below) with Nautilus Merger Sub LLC, a Delaware limited liability company and a wholly owned subsidiary of ET (“Merger Sub”), the Issuer and WP SemGroup Holdco, LLC, a Delaware limited liability company (the “Stockholder”), as a condition of and material inducement to ET, Merger Sub and the Issuer entering into the Merger Agreement (as defined below). As a result of the Support Agreement, the Reporting Persons and the Stockholder may each be deemed to be a member of a group for purposes of Section 13(d). However, each Reporting Person disclaims beneficial ownership of any securities held by the Stockholder.

Item 4.

Purpose of Transaction.

Merger Agreement

On September 15, 2019, ET entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Merger Sub and the Issuer. Upon the terms and subject to the conditions set forth in the Merger Agreement, Merger Sub will merge with and into the Issuer (the “Merger”), with the Issuer continuing as the surviving entity and a subsidiary of ET. On September 15, 2019, the board of directors of LE GP, and the board of directors of the Issuer unanimously approved the Merger Agreement.


CUSIP No. 81663A105		13D

Pursuant to the Merger Agreement, at the effective time of the Merger, and as a result of the Merger:

•

each share of Class A Common Stock of the Issuer will be converted into the right to receive (i) $6.80 in cash, without interest, and (ii) 0.7275 of a common unit representing a limited partner interest in ET (collectively, the “Merger Consideration”);

•

each share of Series A Cumulative Perpetual Convertible Preferred Stock, par value $0.01 per share, of the Issuer (the “Preferred Stock”) will, at the election of the holders of a majority of such shares, either (i) convert into shares entitled to receive the Merger Consideration, (ii) be exchanged for a “substantially equivalent security” or (iii) be redeemed by the Issuer for cash at a price per share equal to 101% of the “liquidation preference”;

•

each award of restricted share units, vested or unvested (other than those held by non-employee directors of the Issuer), will be assumed by ET and converted into a restricted unit award to receive ET common units;

•

each restricted stock award (other than those held by non-employee directors of the Issuer) will be assumed by ET and converted into an ET restricted stock award;

•

each award of performance share units that is outstanding and vested will be cancelled in exchange for the payment of the Merger Consideration, and each award of performance share units that is unvested will be cancelled without consideration; and

•

each restricted stock award and restricted share unit that is held by a non-employee director of the Issuer will become fully vested and will be cancelled in exchange for the payment of the Merger Consideration.

The completion of the Merger is subject to the satisfaction or waiver of customary closing conditions, including: (i) adoption of the Merger Agreement by holders of a majority of the outstanding shares of Class A Common Stock and Preferred Stock (on an as-converted basis), voting as a single class, entitled to vote thereon, (ii) absence of any court order or regulatory injunction prohibiting completion of the Merger, (iii) expiration or termination of review under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), (iv) effectiveness of ET’s registration statement on Form S-4 to register the ET common units to be issued in the Merger, (v) subject to specified materiality standards, the accuracy of the representations and warranties of the other party, (vi) the authorization for listing of ET common units to be issued in the Merger on the New York Stock Exchange, and (vii) compliance by the other party in all material respects with its covenants.

ET and the Issuer have made customary representations and warranties in the Merger Agreement. The Merger Agreement also contains customary covenants and agreements, including covenants and agreements relating to (i) the conduct of each of ET’s and the Issuer’s business between the date of the signing of the Merger Agreement and the closing date of the Merger and (ii) the efforts of the parties to cause the Merger to be completed, including actions which may be necessary to cause the expiration or termination of the waiting period under the HSR Act.


CUSIP No. 81663A105		13D

The Merger Agreement contains certain termination rights for ET and the Issuer. The Merger Agreement further provides that, upon termination of the Merger Agreement under certain circumstances, the Issuer may be required to reimburse ET’s expenses up to $27.25 million or pay ET a termination fee equal to $54.5 million.

Support Agreement

Contemporaneously with the execution of the Merger Agreement, ET and Merger Sub entered into a Support Agreement (the “Support Agreement”) with the Issuer and the Stockholder. Pursuant to the Support Agreement, the Stockholder agreed to, among other things, vote all of its shares in the Issuer that it owns as of the record date for the Issuer’s stockholder meeting (i) in favor of the adoption of the Merger Agreement, (ii) against any acquisition proposal, and (iii) against any action, agreement, transaction or proposal that is intended, would reasonably be expected or the result of which would reasonably be expected, to materially impede, interfere with, delay, postpone, discourage, frustrate the purposes of or adversely affect the Merger or the other transactions contemplated by the Merger Agreement. In addition, the Stockholder has agreed not to dispose of its shares prior to the completion of the Merger and to grant ET an irrevocable proxy to vote its shares in favor of the Merger Agreement in the event that the Stockholder fails to vote in the manner described above.

The foregoing descriptions of the Merger Agreement and the Support Agreement do not purport to be complete and are qualified in their entirety by reference to the full text of such agreements filed as exhibits to this Schedule 13D, and incorporated herein by reference.
