Dear Wayne:


 


Inventergy, Inc. (the “Company”)
is pleased to offer you employment on the following terms:


 


1.          Position.
Your initial title will be VP and General Counsel, and you will initially report to the Company’s CEO, currently Joe Beyers.
This is a full-time position, beginning on the closing date of the initial equity purchase of the Company’s Series A Preferred
Stock (the “Commencement Date”), which is currently expected to be on or about May 10, 2013. While you render
services to the Company, you will not engage in any other employment, consulting or other business activity (whether full-time
or part-time) that would create a conflict of interest with the Company. By signing this letter agreement (the “Agreement”),
you confirm to the Company that you have no contractual commitments or other legal obligations that would prohibit you from performing
your duties for the Company. It is understood and agreed that your outside activities include those listed in Exhibit A.


 


2.          Cash
Compensation. The Company will pay you a starting salary at the rate of $21,875.00 per month, payable in accordance with the
Company’s standard payroll schedule. This salary will be subject to adjustment pursuant to the Company’s employee compensation
policies in effect from time to time. Your monthly salary will increase to $29,166.67 after the completion of a Next Round of Financing
in which the Company’s Board of Directors determines that such an increase complies with all limitations imposed on the Company
pursuant to the terms and conditions of the Series A Preferred Stock investment and the documentation with respect thereto (the
“Approved Milestone”).


 


You will receive a lump-sum
cash bonus (the “Incentive Bonus”) upon the earliest to occur of (a) achievement of the Approved Milestone or
(b) a Change in Control of the Company (such event, the “Trigger Date”), provided you remain continuously employed
by the Company through the date of such event (except as provided under Section 7 below). The amount of the Incentive Bonus will
be equal to 1/3rd of your monthly base salary at the rate then in effect multiplied by the number of months (or
fraction thereof, but in any case, capped at twelve) of full-time employment completed between the Commencement Date and the Trigger
Date.


 


You will also receive an
initial signing bonus in the amount of $56,250.00 on or about the Commencement Date. In addition, you will receive an additional
signing bonus of $18,750.00 to be paid at the earlier of (a) the achievement of the Approved Milestone or (b) the point in which
the Company has received proceeds from the sale by the Company of its equity or debt securities in sufficient amounts such that
the Company’s Board of Directors determine that the Company is able to provide all or portions of this additional signing
bonus and still comply with the limitations imposed by the terms and conditions of the Series A Preferred Stock investment.

3.          Employee
Benefits. As a regular employee of the Company, you will be eligible to participate in a number of Company-sponsored benefits.
In addition, you will be entitled to paid vacation in accordance with the Company’s vacation policy, as in effect from time
to time. The primary place of employment will be at the Company’s Cupertino offices, which may change from time to time at
the Company’s discretion.


 


4.          Equity.
You have been granted 1,500,000 shares of the Company’s Common Stock pursuant to the terms of one or more Stock Grant Agreements
between you and the Company, which such Stock Grant Agreements shall remain in full force and effect (the "Equity Award").
The Equity Award does not guarantee your continued employment for any period of time or your right to receive a future equity grant.


 


5.          Proprietary
Information and Inventions Agreement. Like all Company employees, you will be required, as a condition of your employment with
the Company, to sign the Company’s standard Proprietary Information and Inventions Agreement, a copy of which is attached
hereto as Exhibit B.


 


6.          Employment
Relationship. Employment with the Company is for no specific period of time. Your employment with the Company will be “at
will,” meaning that either you or the Company may terminate your employment at any time and for any reason, with or without
Cause. Any contrary representations, whether written or oral, that may have been made to you are superseded by this Agreement.
This is the full and complete agreement between you and the Company on this term. Although your job duties, title, compensation
and benefits, as well as the Company’s personnel policies and procedures, may change from time to time, the “at will”
nature of your employment may only be changed in an express written agreement signed by you and a duly authorized officer of the
Company (other than you). You agree to abide by all Company policies and procedures as set forth in the Inventergy Employment Manual,
which may be modified from time to time in the Company’s discretion.


 


7.          Severance
Benefits.


 


(a)          General.
If you are subject to an Involuntary Termination, then you will be entitled to the benefits described in this Section 7. However,
this Section 7 will not apply unless you (i) have returned all Company property in your possession, (ii) have resigned
as a member of the Board of Directors of the Company and all of its subsidiaries, to the extent applicable, and (iii) have
executed a general release of all claims that you may have against the Company or persons affiliated with the Company. The release
must be in the form prescribed by the Company, without alterations. You must execute and return the release on or before the date
specified by the Company in the prescribed form (the “Release Deadline”). The Release Deadline will in no event
be later than 50 days after your Separation. If you fail to return the release on or before the Release Deadline, or if you revoke
the release, then you will not be entitled to the benefits described in this Section 7.

(b)          Salary
Continuation. If you are subject to an Involuntary Termination, then, following your Separation, the Company will (i) continue
to pay your monthly base salary during the Severance Period (the “Salary Continuation”) and (ii) if such Involuntary
Termination occurs prior to a Trigger Date, pay you the Incentive Bonus, but only to the extent that the Company’s Board
of Directors determines that such Incentive Bonus payment at the time of your Involuntary Termination complies with all limitations
imposed on the Company pursuant to the terms and conditions of the Series A Preferred Stock investment and the documentation with
respect thereto. The Salary Continuation will be paid at the rate in effect at the time of your Separation and in accordance with
the Company’s standard payroll procedures. The payments under this Section 7 will commence or be paid within 60 days after
your Separation and, once they commence, will include any unpaid amounts accrued from the date of your Separation. However, if
the 60-day period described in the preceding sentence spans two calendar years, then the payments will in any event begin in the
second calendar year. The Severance Period shall be (a) three months if you are subject to an Involuntary Termination prior to
June 1, 2014 and (b) six months if you are subject to an Involuntary Termination on or following June 1, 2014.


 


8.          Tax
Matters.


 


(a)          Withholding.
All forms of compensation referred to in this Agreement are subject to reduction to reflect applicable withholding and payroll
taxes and other deductions required by law.


 


(b)          Tax
Advice. You are encouraged to obtain your own tax advice regarding your compensation from the Company. You agree that the Company
does not have a duty to design its compensation policies in a manner that minimizes your tax liabilities, and you will not make
any claim against the Company or its Board of Directors related to tax liabilities arising from your compensation.


 


(c)          Section
409A. For purposes of Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), each
payment under Section 7(b) is hereby designated as a separate payment. If the Company determines that you are a “specified
employee” under Section 409A(a)(2)(B)(i) of the Code at the time of your Separation, then (i) the payments under
Section 7(b), to the extent that they are subject to Section 409A of the Code, will commence on the first business day
following (A) expiration of the six-month period measured from your Separation or (B) the date of your death and (ii) the
installments that otherwise would have been paid prior to such date will be paid in a lump sum when the salary continuation payments
commence.


 


9.          Interpretation,
Amendment and Enforcement. This Agreement and Exhibit A supersede and replace any prior agreements, representations or understandings
(whether written, oral, implied or otherwise) between you and the Company and constitute the complete agreement between you and
the Company regarding the subject matter set forth herein. This Agreement may not be amended or modified, except by an express
written agreement signed by both you and a duly authorized officer of the Company. The terms of this Agreement and the resolution
of any disputes as to the meaning, effect, performance or validity of this Agreement or arising out of, related to, or in any way
connected with, this Agreement, your employment with the Company or any other relationship between you and the Company (the “Disputes”)
will be governed by California law, excluding laws relating to conflicts or choice of law. You and the Company submit to the exclusive
personal jurisdiction of the federal and state courts located in Santa Clara County in connection with any Dispute or any claim
related to any Dispute.
