As previously reported on a Current Report on Form 8-K filed on December 29, 2016, on December 22, 2016, Inventergy Global, Inc. (the “Parent”), Inventergy Inc., a wholly-owned subsidiary of Parent (the “Owner”), and the other subsidiaries of the Parent (together with the Parent and Owner, the “Company”) entered into a Restructuring Agreement (the “Restructuring Agreement”) with certain entities owned by funds managed by Fortress Investment Group, LLC (“Fortress”) to amend that certain Amended and Restated Revenue Sharing and Note Purchase Agreement, which was originally entered into by the Parent, Owner and Fortress on October 1, 2014.

On March 31, 2017, the parties entered into the First Amendment to the Restructuring Agreement (the “Amendment”), which provides that the Company has until April 30, 2017 to obtain the required approvals to assign the patents covered by the Restructuring Agreement to a newly-created special purpose entity, INVT SPE LLC, a Delaware limited liability company (“INVT SPE”), and for INVT SPE to be in full force and effect. The Amendment also (i) defers any amortization payments on the notes held by Fortress until May 1, 2017, and (ii) suspends the Company’s minimum liquidity covenant until May 1, 2017, each to permit time for the Company to obtain the required approvals and to effect the INVT SPE structure.

The foregoing description of the Amendment does not purport to be complete and is qualified in its entirety by reference to the complete text of such agreement, which is incorporated herein by reference and attached hereto as Exhibit 10.1.

The disclosure set forth in Item 1.01 of this Current Report on Form 8-K is incorporated by reference herein.
