Item 3. Source and Amount of Funds or Other Consideration.

As more fully described under Item 4 below, the Company (known as eOn Communications Corporation prior to the Merger, and for purposes of this statement, referred to as “eOn” when referencing the pre-Merger entity), Inventergy, Inc., a Delaware corporation (“Inventergy”), and Inventergy Merger Sub, Inc., a wholly owned subsidiary of the Company (“Merger Sub”) entered into an Agreement of Merger and Plan of Reorganization (as amended, the “Merger Agreement”), pursuant to which the Reporting Person, Monte Securities Trust (of which the Reporting Person is the beneficiary) and Montalvo Investments, LLC (an entity controlled by the Reporting Person) received an aggregate of 6,716,025 shares of Common Stock of the Company. The consideration for the issuance of such securities was the merger pursuant to the Merger Agreement.

Item 4. Purpose of Transaction.

The Reporting Person acquired the Common Stock based on the Reporting Person’s belief that such an investment represented an attractive investment opportunity. The Reporting Person may purchase additional securities, if the Reporting Person deems that such a transaction represents an attractive investment opportunity, or may similarly dispose of such securities to meet its investment objectives.

Pursuant to the Merger Agreement, on June 6, 2014, Merger Sub merged (the “Merger”) with and into Inventergy with Inventergy continuing as the surviving entity (the “Surviving Subsidiary”). As a result of the Merger, the Surviving Subsidiary became a wholly owned subsidiary of the Company and the name of the Company was changed from “eOn Communications Corporation” to “Inventergy Global, Inc.”

Upon consummation of the Merger, (i) each share of Inventergy common stock was exchanged for 1.4139 shares of Company common stock on a post one-for-two reverse split basis (the “Exchange Ratio”); (ii) the Inventergy Series A Preferred Stock was exchanged for a like number of newly-created Company Series A Preferred Stock; (iii) options and restricted shares of Inventergy common stock awarded pursuant to the Inventergy 2013 Stock Plan and outstanding immediately prior to the consummation of the Merger were converted into awards of options to purchase Company common stock and restricted shares of Company common stock with terms and conditions identical to the terms and conditions of the corresponding options to purchase Inventergy common stock and awards of restricted shares of Inventergy common stock (as adjusted for the Exchange Ratio); and (iv) outstanding warrants to purchase Inventergy common stock were exchanged for warrants to acquire Company common stock with terms and conditions identical to the terms and conditions of the corresponding warrants to purchase Inventergy common stock (as adjusted for the Exchange Ratio). Additionally, certain notes issued by Inventergy to investors were assumed by the Company.

Furthermore and in connection with the Merger, on December 17, 2013, eOn, Cortelco Systems Holding Corp., a Delaware corporation and wholly-owned subsidiary of eOn (“Cortelco Holding”), eOn Communications Systems, Inc., a Delaware corporation and wholly-owned subsidiary of eOn (“eOn Subsidiary”), and Cortelco, Inc., a Delaware corporation and wholly-owned subsidiary of Cortelco Holding (“Cortelco”) entered into a transition agreement (the “Transition Agreement”). The Transition Agreement provided for several transactions among eOn and its subsidiaries in connection with, and subject to the completion of, the Merger. Each of these transactions were consummated at the time the Merger became effective (the “Effective Time”), including the following (collectively, the “Transition Transactions”): (1) eOn and Cortelco each transferred certain contracts and other assets to eOn Subsidiary, and eOn Subsidiary assumed the liabilities associated with such contracts on and after the date of assumption; (2) eOn Subsidiary purchased from Cortelco certain inventory for a purchase price equal to Cortelco’s book value of such inventory; (3) eOn and Cortelco Holding redeemed in full those certain contingent notes in the maximum initial amount of $11 million (collectively, the “Contingent Note”) in consideration of paying the holders of the Contingent Note (the “Noteholders”) either cash in the aggregate amount of $300,000 or shares of Cortelco Holding owned by eOn; (4) Cortelco entered into a fulfillment services agreement with eOn Subsidiary providing for certain services to be conducted on behalf of eOn Subsidiary after the Merger; (5) the Company transferred to Cortelco Holding (i) all of its ownership in Cortelco Systems Puerto Rico, Inc., and Symbio Investment Corp., and (ii) eOn’s right to require David S. Lee, former Chairman of eOn, to purchase its investment in Symbio Investment Corp.; and (6) the Company and Cortelco Holding entered into an indemnity agreement providing that Cortelco will indemnify the Company from and against any future losses arising from the Contingent Note and certain other matters.

Upon completion of the Merger and the Transition Transactions, the Company owns all of the outstanding stock of Inventergy and eOn Subsidiary and has transferred certain assets held prior to the Merger and no longer owns an interest in Cortelco Holding, Cortelco, Cortelco Systems Puerto Rico, Inc., or Symbio Investment Corp.

Immediately following the consummation of the Merger, the Company had 20,018,028 shares of common stock, 6,176,748 shares of Series A Preferred Stock and 2,231 shares of Series B Preferred Stock issued and outstanding. In addition, it had warrants to purchase 700,937 shares of common stock outstanding and 238,412 placement agent warrants outstanding. The former common stockholders of Inventergy received 18,260,022 shares of Company Common Stock as a result of the Merger representing approximately 91% of the Company’s then issued and outstanding Common Stock.

This transaction may be deemed to have resulted in a change in control of the Company from the former stockholders of eOn to the former stockholders of Inventergy.  In connection with the change in control, the Reporting Person, Francis P. Barton, Marshall Phelps, Jr., Robb Knie, W. Frank King and Robert A. Gordon were nominated and elected to the Board of Directors of the Company. The Reporting Person was appointed as the Chief Executive Officer of the Company, Wayne Sobon was appointed Senior Vice President, General Counsel and Secretary of the Company, Jon Rortveit was appointed Senior Vice President, Acquisition and IP Licensing and Stephen Huang was appointed Chief Financial Officer. Each of the executive officers of eOn resigned from their positions at the time the transaction was consummated.  Such appointments and resignations of the officers of the Company were effective on the Closing Date.

The foregoing descriptions of the Merger Agreement and the transactions contemplated thereby are subject to the more detailed provisions set forth in the Merger Agreement and each of the agreements contemplated thereby, which is attached as Exhibit 2.1 to the Current Report on Form 8-K filed by the Company on December 18, 2013, March 25, 2014 (First Amendment) and April 24, 2014 (Second Amendment).
