All of the Shares to which this Statement relates were purchased on behalf of the Reporting Persons using the investment capital of the respective Reporting Person. The aggregate amount of funds used for the purchase of the securities held by the Esopus Reporting Persons was approximately $7,682,748, including commissions. The aggregate amount of funds used for the purchase of the securities held by the Hutch Reporting Persons was approximately $12,186,314, including commissions.

The Reporting Persons acquired the securities disclosed herein based on the Reporting Persons’ belief that the securities, when acquired, were undervalued and represented an attractive investment opportunity. The Reporting Persons had previously acted as a group which was dissolved in May of 2020.

On February 22nd, 2021 the Reporting Persons held a video meeting with the Issuer's Chief Executive Officer, Chief Financial Officer, its lead Director, and a representative from the Issuer's largest shareholder. As described in the attached presentation (the “Presentation”), the Reporting Persons recommended that the Issuer undertake a recapitalization with a $150 million common stock repurchase through a modified Dutch tender auction with a proposed minimum price of $6.50 per Share up to a proposed maximum price of $7.25 per share, depending upon additional terms and conditions. The Reporting Persons suggested funding for the tender should consist of $50 million of balance sheet cash and the issuance of up to $100 million of preferred shares. The Reporting Persons noted that such a Dutch tender program, depending upon price and the number of Shares tendered, could result in the retirement of up to approximately 23 million Shares of Common Stock or up to approximately 30% of the Common Stock outstanding. The Reporting Persons believe that market conditions are such that the Issuer may be able to successfully offer up to $100 million worth of preferred stock to institutional investors in light of the approximately $400 million worth of unexercised options, held by the U.S. Government, to purchase additional courses of the Issuer's FDA approved biodefense drug, TPOXX, the smallpox antiviral currently supplied by the Issuer to the U.S. Strategic National Stockpile.

 At this stage none of the Reporting Persons intend to tender their Shares.

At the conclusion of the February 22nd meeting, the Reporting Persons requested a follow-up meeting with the same parties to further discuss the proposal once the Issuer's Board of Directors, Management and any relevant financial advisors have had a sufficient opportunity to properly consider the Reporting Persons' proposal.

Depending upon 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 securities desirable, the Reporting Persons may endeavor from time to time (i) to increase or decrease its position 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 Reporting Persons may deem advisable and/or (ii) to enter into transactions that increase or hedge its economic exposure to the securities of the Issuer without affecting its beneficial ownership.

Except as otherwise disclosed in this Item 4 or the Presentation, the Reporting Persons do 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 completion of any of the actions discussed herein. The Reporting Persons intend to review their investment in the Issuer on a periodic basis and may from time to time engage in discussions with management and the Board and other shareholders and potential shareholders of the Issuer concerning, among other things, the business, operations and future plans of the Issuer. Depending on various factors including, without limitation, the Issuer’s financial position and investment strategy, the price levels of the securities of the Issuer, conditions in the securities markets and general economic and industry conditions, the Reporting Persons may in the future take such actions with respect to their respective investments in the Issuer as they deem appropriate including, without limitation, making proposals concerning changes to the capitalization, ownership structure, Board composition or operations of the Issuer, purchasing additional securities of the Issuer, selling some or all of its securities of the Issuer, engaging in short selling of or any hedging or similar transaction with respect to the securities of the Issuer, or changing its intention with respect to any and all matters referred to in this Item 4.
