Europe Limited ("H.E.C."), from the shareholders of H.E.C. (the "Sellers"), for the aggregate consideration of approximately $367 million, which would include the assumption of certain indebtedness payable in the form of a combination of debt, the assignment of certain accounts receivables, cash and shares of the Issuer’s Common Stock (the "Consideration Shares"), which would represent approximately 33% of the issued and outstanding Common Stock of the Issuer after giving effect to the issuance (the “Transaction”). The Issuer stated that the Sellers were companies owned and controlled by the Issuer’s founder and former Head of Corporate Development Dimitris Melisanidis, and certain members of his family, and members of the Agiostratitis family (collectively, the "Seller Owners"). In connection with the Agreement, the Issuer also announced proposed changes to the Board upon the closing of the Transaction in which the Sellers, subject to certain conditions, would designate two nominees for appointment or election to the Board, and the Issuer would appoint one additional independent director to the Board effective as of the closing of the Transaction, thereby creating an eight-member Board. The Issuer further stated that the Transaction did not require approval from shareholders under its Articles of Incorporation.

On March 7, 2018, Messrs. Baron, Moore and Roth contributed all of their Shares, except for 1,000 Shares each, to RBM Holdings LLC (“RBM”), in exchange for limited liability company interests in RBM. Mr. Baron is the manager of RBM.

On March 8, 2018, RBM filed an action for a temporary restraining order (the “TRO”) in the United States District Court in the Southern District of New York to seek to enjoin the Transaction based on, among other factors, its likelihood to dilute and disenfranchise the Issuer’s existing shareholders . On March 12, 2018, Judge Preska granted the TRO and enjoined the proposed Transaction for fourteen days. On March 16, 2018, Judge Preska extended the TRO until April 9, 2018 and granted the Reporting Persons’ motion for expedited discovery. The parties to the litigation agreed to temporarily stay the proceeding and filed a stipulation and scheduling order on March 20, 2018, setting out the terms of the temporary stay.

On March 27, 2018, the Issuer announced the expiration of the Agreement since the contractual deadline of March 27, 2018 for obtaining all necessary approvals for the Agreement had not been waived, and that the Agreement therefore had terminated in accordance with its terms.
