Attn: Joseph Beyers

Dear Mr. Beyers:

This Non Binding Letter of Intent (this “Letter of Intent”) outlines the general terms and conditions pursuant to which Inventergy Global, Inc. (“you” and, together with your subsidiaries, the “Company”) have proposed that DBD Credit Funding LLC and its affiliates (“we” or “DBD”) consider agreeing to a restructuring of the obligations of the Company under that certain Amended and Restated Revenue Sharing and Note Purchase Agreement dated as of October 1, 2014 (as amended and in effect, the “Agreement” and such existing obligations, the “Obligations” and the proposed restructuring, the “Proposed Restructuring”). What we understand to be the material terms of the Proposed Restructuring are set forth in the proposed Summary Term Sheet attached as Exhibit A hereto. Terms used in the Summary Term Sheet and not defined shall have the meanings provided in the Agreement.

If we have correctly described the Proposed Restructuring, please indicate your agreement by countersigning below.

This Letter of Intent constitutes a non binding indication of willingness on our part to explore the Proposed Restructuring, and your agreement to pay our expenses in connection with such exploration regardless whether the Proposed Restructuring is consummated. In furtherance of, and as evidence of our willingness to explore, the Proposed Restructuring, we have agreed to an amendment to the Agreement that extends the time for performance of certain of the Company’s obligations under the Agreement from September 30, 2016 to October 30, 2016.

Notwithstanding any provision of this Letter of Intent, or any other action of the parties, we are not bound to the Proposed Restructuring unless and until definitive documentation is agreed to by both we and you (“Definitive Documentation”), and until any conditions to the completion of the Proposed Restructuring that are set forth in the Definitive Documentation have been satisfied.

Without limiting the foregoing this Letter of Intent may not be relied upon by the Company or any other party as the basis for a contract by estoppel or otherwise. Moreover, no past, present or future action, course of conduct, or failure to act relating to the Proposed Restructuring or relating to the negotiation of the terms of such transaction will give rise to or serve as the basis for any obligation or other liability on the part of DBD or any of its affiliates. Any such agreement by the parties shall only be provided for in the Definitive Documentation, if and when such Definitive Documentation has been agreed to and executed.

No party shall be entitled to rely on this Letter of Intent for any reason, and the Company agrees to fully indemnify and hold DBD harmless from any third party claims, including the expenses of defense. Without limiting the foregoing, the parties agree, confirm and acknowledge that no shareholder or other investor in, or lender to, the Company, and no prospective shareholder or other investor in, or lender to, the Company, shall have any rights, derivative or otherwise, under this Letter of Intent, and the parties do not intend for any third party reliance to be created under this Letter of Intent.

This Letter of Intent may be executed in any number of counterparts and any party hereto may execute any such counterpart, each of which when executed and delivered will be deemed to be an original and all of which counterparts when taken together will constitute but one and the same instrument.

This Letter of Intent, the rights and obligations of the parties hereto, and any claims or disputes relating thereto, will be governed by and construed under and in accordance with the laws of the State of New York, without regard to any conflicts of law principles that would result in the application of any law other than the laws of the State of New York. Each party to this Letter of Intent hereby irrevocably and unconditionally submits, for itself and its property, to the exclusive jurisdiction of the United States District Court, or if such court does not have jurisdiction, any New York State court, in either case sitting in New York, New York, and any appellate court thereof, in any action or proceeding arising out of or relating to this Letter of Intent or for recognition or enforcement of any judgment relating thereto, and each of the parties hereby irrevocably and unconditionally (a) agrees not to commence any such action or proceeding except in such courts, (b) agrees that any claim in respect of any such action or proceeding may be heard and determined in such court, (c) waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any such action or proceeding in any such court, and (d) waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.

Please acknowledge your acceptance of and agreement to the foregoing by signing and returning to the undersigned as soon as possible a counterpart of this Letter of Intent.

ACCEPTED AND AGREED TO AS OF
