Upon approval by STCN's stockholders, the Series E Preferred Stock will be convertible into an aggregate of 184,891,318 shares of common stock, par value $0.01 per share, of STCN (the "STCN Common Shares"), subject to adjustment as set forth in the Certificate of Designation, and will vote together with the STCN Common Shares and participate in any dividends paid on the STCN Common Shares (except as described below), in each case, on an as-converted basis. Stockholders' Agreement Concurrently with the execution of the Exchange Agreement, the Company, Steel Excel, WebFinancial, WHX CS, LLC, WF Asset Corp., Steel Partners Ltd., Warren G. Lichtenstein and Jack L. Howard (together, the "SP Investors") and STCN entered into a Stockholders' Agreement dated as of April 30, 2023 (the "Stockholders' Agreement"). Pursuant to the Stockholders' Agreement, the parties agreed to certain aspects of STCN's governance, including the creation of an Independent Audit Committee or Disinterested Audit Committee (as defined therein). The Stockholders' Agreement further provides that (A) prior to September 1, 2025 the prior approval of the Independent Audit Committee or the Disinterested Audit Committee, as applicable, is required for the following: (i) a voluntary delisting of the STCN Common Shares from the applicable stock exchange or a transaction (including a merger, recapitalization, stock split or otherwise) which results in the delisting of the STCN Common Shares, STCN ceasing to be an SEC reporting company, or STCN filing a Form 25 or Form 15 or any similar form with the SEC; (ii) an amendment to the terms of the Management Services Agreement (the "Services Agreement") dated June 14, 2019, by and between STCN and Steel Services Ltd.; and (iii) any related party transaction between STCN and the SP Investors and their subsidiaries and affiliates; (B) prior to September 1, 2028, the prior approval of the Independent Audit Committee or the Disinterested Audit Committee, as applicable, is required for the Board to approve a going private transaction pursuant to which Steel Partners or its subsidiaries or affiliates acquires the outstanding STCN Common Shares they do not own (or any alternative transaction that would have the same impact); and (C) until the Final Sunset Date, the prior approval of the Independent Audit Committee or the Disinterested Audit Committee, as applicable, is required (i) for the Board to approve a short-form or squeeze-out merger between STCN and the SP Investors; or (ii) prior to any transfer of equity interests in STCN by the members of the SP Group (as defined in the Stockholders' Agreement) if such transfers would result in 80% of the voting power and value of the equity interests in STCN that are held by the members of the SP Group being held by one corporate entity. The Stockholders' Agreement also provides that 70% of the net proceeds received by STCN upon resolution of the Reith litigation will be distributed to STCN's stockholders with the SP Investors agreeing to waive their portion of any such distribution to the extent of any STCN Common Shares held as of the date of the Stockholders' Agreement or issuable upon conversion of the Series E Preferred Stock held by the SP Investors and the Series C Convertible Preferred Stock, par value $0.01 per share, of STCN, and the STCN Note. Any amendment to the Stockholders' Agreement by STCN prior to the date that any person or group of related persons owns 100% of the equity securities of STCN requires the prior approval of the Independent Audit Committee or the Disinterested Audit Committee, as applicable. Voting Agreement Concurrently with the execution of the Exchange Agreement, the SP Investors and STCN entered into a Voting Agreement, dated as of April 30, 2023 (the "Voting Agreement"). Pursuant to the terms and conditions set forth in the Voting Agreement, each SP Investor has agreed to (i) vote, or cause to be voted, all securities of STCN beneficially owned by each such SP Investor for the approval of the Nasdaq Proposal and against any transaction or proposal that may delay, impair or nullify the approval of the Nasdaq Proposal; (ii) not enter into an agreement to vote in a manner inconsistent with the foregoing; and (iii) not transfer such STCN Common Shares and Subject Shares (as defined in the Stockholders' Agreement), without the prior consent of STCN's audit committee, subject to certain standard exceptions. As the SP Investors currently own more than a majority of the voting power of STCN, approval of the Nasdaq Proposal is assured. The STCN Board of Directors (the "STCN Board"), acting on the unanimous recommendation of a strategic planning committee of the STCN Board consisting solely of independent and disinterested directors of STCN (the "Strategic Planning Committee"), approved the Transaction. The Strategic Planning Committee exclusively negotiated the terms of the Transaction with Steel Partners, with the assistance of its independent legal counsel and financial advisors, which also issued a fairness opinion with respect to the Transaction.
