**Item 4. Purpose of Transaction**

Pursuant to the SPA, as further described in Item 6, effective as of August 19, 2025, (a) the Reporting Person was appointed as the Chief Executive Officer and a member of the Issuer's Board of Directors, and (b) Justin Hall resigned as the Chief Executive Officer of the Issuer, though he will remain a named executive officer of the Issuer and serve as the Vice President of Business Development, General Counsel and Corporate Secretary of the Issuer and continue to serve on the Issuer's Board of Directors.

In addition to the Reporting Person being appointed as a director and Chief Executive Officer of the Issuer in connection with the transactions described in Item 6, pursuant to the SPA, the Reporting Person will have certain one-time contractual rights involving the Issuer's Board of Directors. These rights include: (i) a one-time contractual right to recommend to the Issuer one (1) individual to be nominated for election at the Issuer's 2025 annual meeting of stockholders (the "Annual Meeting") to serve as a director on the board, provided that at the time this right is exercised, the Reporting Person continues to own his shares of Series D Preferred Stock; (ii) subject to the Stockholder Approval (as defined in the SPA) and the Final Closing occurring, a one-time contractual right to nominate up to three (3) individuals (the "Additional Purchaser Nominees") to be qualified (including satisfying director "independence" requirements set forth in the NYSE American Company Guide) and appointed to serve as directors on the Issuer's Board of Directors after the resignation of the current directors (other than the Continuing Director (as defined below), following the Stockholder Approval, the approval of certain equity consideration to the resigning non-employee directors (the "Equity Consideration Approval")) and the Final Closing occurring, as provided in such resigning director's release agreements; and (iii) subject to the Stockholder Approval and the Final Closing occurring, a one-time contractual right to be appointed as the Chair of the Issuer's Board of Directors.

The Reporting Person does not have 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 Person intends to review his investment in the Issuer on a continuing basis. Depending on various factors including, without limitation, the Issuer's financial position and investment strategy, the price levels of the Shares, conditions in the securities markets and general economic and industry conditions, the Reporting Person may in the future take such actions with respect to his investment in the Issuer as he deems appropriate including, without limitation, engaging in additional communications with management and the Issuer's Board of Directors, engaging in discussions with stockholders of the Issuer or other third parties about the Issuer and the Reporting Person's investment, including potential business combinations or dispositions involving the Issuer or certain of its businesses, making recommendations or proposals to the Issuer concerning changes to the capitalization, ownership structure, board structure (including board composition), potential business combinations or dispositions involving the Issuer or certain of its businesses, or suggestions for improving the Issuer's financial and/or operational performance, purchasing additional Shares, selling some or all of his Shares, engaging in short selling of or any hedging or similar transaction with respect to the Shares, including swaps and other derivative instruments, or changing his intention with respect to any and all matters referred to in Item 4.

On August 19, 2025, the Issuer, the Reporting Person, and each of Mr. Jed Fakhry, an individual, Poplar Point Capital Management LLC, Poplar Point Capital Partners LP, and Poplar Point Capital GP LLC (such entities other than the Issuer and the Reporting Person, collectively, the "Poplar Entities"), entered into a Voting Agreement (the "Voting Agreement"), which became effective upon the execution and effectiveness of the SPA and will have a two year term.

Pursuant to the terms of the Voting Agreement, the Poplar Entities have agreed to (1) vote all of their shares of Common Stock at the Annual Meeting in favor of the proposals recommended by the Issuer's Board of Directors in order to facilitate the investment contemplated by the SPA (the "Meeting Proposals"), (2) the appointment of the Issuer as an irrevocable proxy for the Poplar Entities for the duration of the Voting Agreement, and (3) the ability of the Issuer to appoint a successor proxy for the Poplar Entities, in the event the Issuer is unable or unwilling to serve as the proxy, and in return, the Poplar Entities will benefit from the Issuer completing the investment contemplated by the SPA. The Voting Agreement provides for, among other things, a standstill provision relating to the Poplar Entities that ensures they will (i) not effect, offer or propose to purchase any additional securities or assets of the Issuer (including derivative rights), engage in any tender, merger, recapitalization, liquidation, or other business combination transaction, solicit proxies or otherwise act to control or influence the management of the Issuer's Board of Directors, (ii) not take any action (or enter into any discussions) that may force the Issuer to make a public announcement of the matters set forth in (i) above, (iii) not request that the Issuer (or directors, management, employees or agents) amend or waive any provision of the standstill and (iv) not dispose of any shares of the Issuer until (1) the Poplar Entities have voted their shares of Common Stock at the Annual Meeting in favor of the Meeting Proposals and (2) such proposals at the Annual Meeting have passed. Notwithstanding the standstill provision, the Poplar Entities can make proposals to the Issuer's Board of Directors or special committee of the same, the Chairman, and/or the Chief Executive Officer of the Issuer on a confidential, non-public basis for each of (a) the pursuit of a proposed transaction between the Issuer, the Reporting Person and the Poplar Entities, so long as the Issuer would not reasonably be expected to publicly disclose such a proposal and (b) a waiver of the standstill provision.

The Reporting Person disclaims formation of a group with Jed Fakhry and the Poplar Entities, and of any shared beneficial ownership with such parties.

The foregoing description of the Voting Agreement does not purport to be complete and is qualified in its entirety by the reference to the Voting Agreement, which is filed as an exhibit to this Schedule 13D, and is incorporated by reference herein.

On August 19, 2025, the Issuer entered into the SPA with the Reporting Person, pursuant to which the Reporting Person agreed to acquire from the Issuer (i) an aggregate of 481,250 shares of Series D Preferred Stock convertible into an aggregate of 77.0 million shares (the "Series D Conversion Shares") of the Issuer's Common Stock for $3.85 million and (ii) an aggregate of 268,750 shares of Series E Preferred Stock, convertible into an aggregate of 43.0 million shares (the "Series E Conversion Shares", and, together with the Series D Conversion Shares, the "Conversion Shares") of Common Stock for an additional $2.15 million.

Pursuant to the SPA, the Reporting Person has the right to assign and transfer the Series D Preferred Stock, the Series E Preferred Stock and the Conversion Shares and/or his right to acquire such securities (collectively, the "Securities Purchase Rights"), or the option to sell the Securities Purchase Rights, subject to the Reporting Person and the transferee satisfying certain requirements under to the SPA.

The SPA contains customary representations, warranties and agreements of the Issuer and the Reporting Person, limitations, and conditions regarding sales of the Common Stock, indemnification rights and other obligations of the parties.

Furthermore, the Issuer and Reporting Person agree to be bound by certain covenants pursuant to the SPA, as more fully set forth therein. The Issuer also granted the Reporting Persona right to participate in subsequent financing transactions where the Issuer issues Common Stock or Common Stock equivalents for cash consideration, indebtedness or a combination thereof.

The  Issuer's Board of Directors has adopted resolutions (i) exempting the Reporting Person's acquisition of the Common Stock from Section 16(b) of the Exchange Act of 1934, as amended, pursuant to Rule 16b-3 and (ii) granting the Reporting Person the right to sell, assign or otherwise transfer either the Series D Preferred Stock or Series E Preferred Stock (as well as any Common Stock underlying any such Series D Preferred Stock or Series E Preferred Stock) or his rights to acquire the Series D Preferred Stock or Series E Preferred Stock (as well as any Common Stock underlying any such securities) pursuant to the SPA (the "Securities Purchase Rights"), including by way of option for the Reporting Person to sell and/or a transferee thereof to purchase, the Securities Purchase Rights.
