Item 8.01. Other Events.

On August 3, 2018 (the “Closing Date”), Ribbon Communications Inc. (“Ribbon”) completed its acquisition of Edgewater Networks, Inc., a Delaware corporation (“Edgewater”), through the merger of Kansas Merger Sub, Inc., a Delaware corporation and a direct wholly-owned subsidiary of Ribbon (“Merger Sub”), with and into Edgewater, with Edgewater surviving such merger as a wholly-owned subsidiary of Ribbon (the “Merger”).  The Merger was completed in accordance with the terms and conditions of the Agreement and Plan of Merger, dated as of June 24, 2018, by and among Ribbon, Merger Sub, Edgewater and Shareholder Representative Services LLC, a Colorado limited liability company, solely in its capacity as the initial holder representative (the “Merger Agreement”).

Ribbon authorized the payment of $50 million in cash, subject to adjustment in accordance with the terms of the Merger Agreement, representing the cash consideration to be paid at the closing of the Merger (the “Closing Cash Consideration”). Ribbon funded the entirety of the Closing Cash Consideration through funds drawn down, on the Closing Date, from revolving credit facilities available pursuant to that certain Credit Agreement, dated as of December 21, 2017, as amended, with Silicon Valley Bank, as Administrative Agent, Issuing Lender, Swingline Lender and Lead Arranger, and the other lenders party thereto (the “Credit Facility”).  The material terms of the Credit Facility (including amendments thereto) are described in Ribbon’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (the “SEC”) on March 8, 2018 and Ribbon’s subsequent periodic reports filed with the SEC.

In addition, on the Closing Date and pursuant to the Merger Agreement, Ribbon authorized the issuance of up to 4,235,614 shares of Ribbon common stock (equivalent to $30 million, as calculated in accordance with the terms of the Merger Agreement) by American Stock Transfer & Trust Company LLC, as exchange agent, to certain holders of Edgewater common stock (“Edgewater Common Stock”) and preferred stock (“Edgewater Preferred Stock”, and, together with the Edgewater Common Stock, the “Edgewater Company Stock”), certain holders of in-the-money warrants to acquire Edgewater Company Stock and certain holders of vested, in-the-money options to acquire Edgewater Common Stock (collectively, the “Pre-Closing Holders”), in partial consideration for the Merger (the “Stock Consideration”).  The issuance of the Stock Consideration will be made in reliance on an exemption from the registration provisions of the Securities Act of 1933, as amended, set forth in Section 4(a)(2) thereof, relative to sales by an issuer not involving a public offering.  Pre-Closing Holders who are not “Accredited Investors” are not entitled to receive any Stock Consideration.

Pursuant to the Merger Agreement and subject to the terms and conditions contained therein, Ribbon has agreed to pay the Pre-Closing Holders (i) an additional $15 million in cash six months following the Closing Date, and (ii) an additional $15 million in cash as early as nine months following the Closing Date and no later than eighteen months following the Closing Date (the exact timing of which will depend on the amount of revenue generated from the sales of Edgewater products in 2018).
