The information contained in Item 4 of the Schedule 13D is hereby amended to delete the last three paragraphs thereof and supplemented to include the following information: On September 26, 2025, the Reporting Person entered into a Stock Exchange Agreement (the "Exchange Agreement") with the Issuer pursuant to which, among other things, at the closing of the transactions contemplated thereby (the "Closing"), and on the terms and subject to the conditions set forth therein, the Reporting Person will exchange (the "Exchange") the 31,928,301 shares of Series B Convertible Preferred Stock, par value $0.001 per share ("Series B Preferred Stock"), of the Issuer currently owned by the Reporting Person for (i) 4,223,621 shares of a new series of convertible preferred stock to be designated as Series C Convertible Preferred Stock, par value $0.001 per share ("Series C Preferred Stock"), and (ii) 3,286,825 shares of Common Stock. As of the Closing, the shares of Series C Preferred Stock will originally be convertible into shares of Common Stock on a one-to-one basis. The shares of Series C Preferred Stock will have the terms and conditions set forth in the Certificate of Designations for the Series C Preferred Stock. Also on September 26, 2025, in connection with the execution of the Exchange Agreement, the Reporting Person entered into a Stockholder Support Agreement with the Issuer (the "Support Agreement"), pursuant to which, among other things, the Reporting Person agreed to, at a meeting of the Issuer's stockholders, vote in favor of the approval of (a) the issuance of Series C Preferred Stock and Common Stock in the Exchange, (b) a Certificate of Amendment to the Issuer's Amended and Restated Certificate of Incorporation and (c) any other proposal put forth by the Issuer in connection with the Exchange, except that the Reporting Person will vote to "abstain" on any proposal seeking approval of the disinterested stockholders of the Issuer. Under the Support Agreement, the Reporting Person has agreed not to, directly or indirectly, Transfer (as defined in the Support Agreement) any shares of Common Stock or Series B Preferred Stock that the Reporting Person is entitled to vote on the matters submitted to the Issuer's stockholders at the stockholders meeting. The Support Agreement terminates upon the termination of the Exchange Agreement. In connection with the Closing, the Issuer, Charter Communications Holding Company, LLC ("Charter") and Pine Investor, LLC ("Pine" and, together with the Reporting Person and Charter, referred to herein collectively as the "Stockholders") will enter into a Second Amended and Restated Stockholders Agreement (the "Second Amended and Restated SHA"), pursuant to which, among other things, immediately following the Closing, the Issuer is obligated to take all necessary action to ensure that the board of directors of the Issuer (the "Board") and certain committees thereof consist of the individuals set forth in the Second Amended and Restated SHA, including the applicable designees of each Stockholder, in each case, as more particularly set forth in the Second Amended and Restated SHA. Upon Closing, the Board will consist of seven total directors: one designee of each Stockholder, one Additional Director (as defined in the Second Amended and Restated SHA), and three directors who are not (a) a designee of any Stockholder or (b) for so long as the Stockholders have the ability to designate at least one director pursuant to the Second Amended and Restated SHA, an individual who is an affiliate of such Stockholders, including the chief executive officer of the Issuer. At the Closing, the Issuer will also amend its Registration Rights Agreement, dated as of March 10, 2021, by and among the Issuer and the other parties thereto (the "RRA", and such amendment, the "RRA Amendment"). The RRA Amendment, among other things, will amend the definition of "Registrable Securities" under the RRA to include shares of Series C Preferred Stock and shares of Common Stock issued upon conversion of the Series C Preferred Stock. The foregoing summary of the Exchange Agreement, the Support Agreement, the Second Amended and Restated SHA and the RRA Amendment does not purport to be complete and is subject to, and is qualified in its entirety by, the full text of the Exchange Agreement and the substantially final form of the Second Amended and Restated SHA, which are included as Exhibit 7(a) hereto, the full text of the Support Agreement, which is included as Exhibit 7(b) hereto, and the full text of the substantially final form of the RRA Amendment, which is included as Exhibit 7(c) hereto, and are incorporated herein by reference. The shares of Common Stock beneficially owned by the Reporting Person and described in this Statement are being held by the Reporting Person for investment purposes. Other than as set forth in this Amendment, the Reporting Person does not have any present plans or proposals which relate to or would result in: (i) any acquisition by any person of additional securities of the Issuer, or any disposition of securities of the Issuer; (ii) any extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving the Issuer or any of its subsidiaries; (iii) any sale or transfer of a material amount of assets of the Issuer or any of its subsidiaries; (iv) any change in the board or management of the Issuer, including any plans or proposals to change the number or term of directors or to fill any vacancies on the board; (v) any material change in the present capitalization or dividend policy of the Issuer; (vi) any other material change in the Issuer's business or corporate structure; (vii) any change in the Issuer's charter or bylaws or other actions which may impede the acquisition of control of the Issuer by any person; (viii) any delisting from a national securities exchange or any loss of authorization for quotation in an inter-dealer quotation system of a registered national securities association of a class of securities of the Issuer; (ix) any termination of registration pursuant to Section 12(g)(4) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), of a class of equity securities of the Issuer; or (x) any action similar to any of those enumerated above. Notwithstanding the foregoing, the Reporting Person may determine to change its intentions with respect to the Issuer at any time in the future and may, for example, elect (i) to acquire additional securities of the Issuer in open market or privately negotiated transactions or (ii) to dispose of all or a portion of the Reporting Person's holdings of securities of the Issuer. In reaching any determination as to its future course of action, the Reporting Person will take into consideration various factors, such as the Issuer's business and prospects, other developments concerning the Issuer, other business opportunities available to the Reporting Person, tax considerations, liquidity needs and general economic and stock market conditions, including, but not limited to, the market prices of the securities.
