Item 4.

Purpose of Transaction.

On March 6, 2019, Mangrove Partners, Bluescape Energy Partners LLC, a Delaware limited liability company (“Bluescape Energy Partners”), and Cove Key Bluescape Holdings entered into a Cooperation Agreement (the “Cooperation Agreement”) whereby, among other things, they agreed to coordinate and cooperate in certain activities related to their ownership of the common shares of the Issuer any other voting or equity securities of the Issuer, any securities convertible into voting or equity securities of the Issuer, and derivative contracts. The foregoing description of the Cooperation Agreement is qualified in its entirety by reference to the full text of the Cooperation Agreement, which is attached as Exhibit B hereto and is incorporated herein by reference.

Accordingly, the Reporting Persons may be deemed a group (such group, the “Group”) for the purposes of Section 13(d)(3) of the Act. Each of the Reporting Persons expressly disclaims beneficial ownership of any shares of Common Stock of the Issuer, any other voting or equity securities of the Issuer, any securities convertible into voting or equity securities of the Issuer, and derivative contracts acquired or held by the other members of the Group.

On March 12, 2019, Mangrove Partners and Cove Key Bluescape Holdings entered into a Share Purchase Agreement (the “Share Purchase Agreement”), pursuant to which Mangrove Partners sold 6,591,154 shares of Common Stock to Cove Key Bluescape Holdings for a total purchase price of USD $40,000,000. The foregoing description of the Share Purchase Agreement is qualified in its entirety by reference to the full text of the Share Purchase Agreement, which is attached as Exhibit C hereto and is incorporated herein by reference.

The Group entered into the Cooperation Agreement and purchased the shares of Common Stock reported herein based on its belief that such shares were undervalued and that the Issuer can create significantly more value for shareholders through improved execution and focus. Members of the Group have spoken to, and intend to continue to speak with, representatives of the Issuer’s board of directors and management to discuss enhancing shareholder value and seeking board representation.

The Group believes that there exist numerous opportunities to increase shareholder value, including through operational and cost excellence, asset optimization, capital allocation and broader strategic initiatives.

The Group believes that Charles John Wilder, Jr. and his team have directly relevant experience in effecting such improvements at non-regulated electricity generation and energy marketing companies as well as a long track record of creating value for all shareholders. The Group looks forward to holding discussions with the Issuer’s board of directors to address these opportunities as well as to implement appropriate board-level oversight.

Depending upon other factors, including overall market conditions, other investment opportunities available to the Reporting Persons, and the availability of securities of the Issuer at prices that would make the purchase or sale of such shares desirable, the Group may endeavor (i) to increase or decrease their respective positions in the Issuer through, among other things, the purchase or sale of securities of the Issuer on the open market or in private transactions or otherwise on such terms and at such times as the Group may deem advisable and/or (ii) to enter into transactions that increase or hedge their economic exposure to the shares of Common Stock without affecting their beneficial ownership of shares of Common Stock. The Group is also evaluating the nomination of one or more individuals for election as directors of the Issuer at the 2019 annual meeting of stockholders of the Issuer.

No Reporting Person has any present plan or proposal which would relate to or result in any of the matters set forth in subparagraphs (a) - (j) of Item 4 of Schedule 13D except as set forth herein or such as would occur upon or in connection with completion of, or following, any of the actions discussed herein. The Reporting Persons may take positions regarding or make precatory, conditional or binding proposals with respect to, or with respect to potential changes in, the Issuer’s: operations, management, certificate of incorporation and bylaws, composition of the board of directors of the Issuer or its committees, ownership, capital or corporate structure, dividend policy, potential acquisitions or sales, businesses or assets, including the sales thereof, strategy and/or plans of the Issuer as a means of enhancing stockholder value. The Reporting Persons may change their intention with respect to any and all matters referred to in Item 4. The Reporting Persons intend to review their investment in the Issuer on an ongoing basis and may from time to time in the future express their views to and/or meet with management, the board of directors of the Issuer, other stockholders or third parties, including, potential acquirers, service providers and financing sources, and/or may formulate plans or proposals regarding the Issuer, its assets or its securities.
