Commitments and Contingencies Disclosure [Text Block]	*17.* Commitments and Contingencies On March 19, 2021, a putative class action complaint, captioned Litwin v. Cleveland BioLabs, Inc. et al., Case 2021-0242, was filed in the Delaware Court of Chancery in connection with the Merger (the “Litwin Action”). The Litwin Action names as defendants Cleveland BioLabs, each director on the Cleveland BioLabs board of directors, and the Vice President of Finance of Cleveland BioLabs. The complaint in the Litwin Action alleges that Defendants omitted and/or provided misleading information in the registration statement on Form S-4 filed with the SEC in connection with the Merger, of which this proxy statement/prospectus forms a part, in breach of their fiduciary duties. The Litwin Action seeks, among other things, an injunction preventing the closing of the Merger, rescission of the merger if it is consummated, the dissemination by Cleveland BioLabs of a revised registration statement on Form S-4 and an award of plaintiffs’ attorneys’ and experts’ fees. Plaintiff in the Litwin Action has filed a motion for expedited proceedings, which Defendants have opposed. Plaintiff’s motion for expedited proceedings was granted in part and denied in part by the court on April 30, 2021. Defendants have also filed a motion to dismiss the Litwin Action. On July 7, 2021, Plaintiff filed a stipulation and proposed order voluntarily dismissing the case but reserving the right to seek attorneys’ fees. On July 8, 2021, the Delaware Court of Chancery entered an order dismissing the case but reserving jurisdiction to determine whether to award Plaintiff’s counsel any fees, should Plaintiff’s counsel file a motion for such. As of the balance sheet date management believes that it is probable that a settlement will be reached. Management estimates the likely settlement amount to be $275,000, therefore we have accrued this amount in accounts payable and accrued expenses.
