2.4Shared Revenue.
In addition to the Purchase Payment of Section 2.1, Assignee shall pay Assignor Shared Revenue of * percent (*%) (“Net Revenue
Percentage”) of Net Revenue. Beginning with the first calendar quarter following the Effective Date of this Agreement, and
continuing each quarter thereafter, Assignee shall provide Assignor with a statement, accompanied with reasonable sufficient supporting
documentation for the defined revenue and expense calculations of Section 1.12, of the amount of Net Revenue received during the
immediately preceding calendar quarter along with the Shared Revenue payment due, if any. Such statement and Shared Revenue payments
shall be due within thirty (30) calendar days following the last day of each quarter. If Huawei * any of its * as set forth in
Section *, then for each such *, the * will be reduced for * (or earlier if that particular * ends earlier (pursuant to particular
provisions of Section *)) in the following fashion: if only * is currently in effect during any period, the * will be * at Year
*, another * at Year *, and yet another * at Year *, the * will be reduced to *% from the beginning of year * to the beginning
of year *; to *% between the start of Year * to Year *; *% between Year * and the start of Year *; back up to *% between the start
of Year * and the start of Year * (because the next * is then the primary existing * after the previous * ends and therefore reduces
the * by *% rather than the previous *%); increases to *% between the start of Year * and Year * (the final * now being primary),
and thereafter back * to the *%.


 


(a) For any
potential transaction in which Net Revenue may be realized and for which the transaction involves a mixture of Transferred Patents
and other patents owned by Assignee, the Parties agree to negotiate in good faith for the appropriate apportionment of the revenue
as well as the expenses per Section 1.12 prior to concluding such a transaction


 


(b)
For any * of any of the Transferred Patents by Assignee, Assignor is granted * for such action, except in cases of (i) * and (ii)
*).


 


2.5Taxes. All payments
to be made by the Assignee to the Assignor under this Section 2 shall be made without any set-off, counterclaim, withholding or
deduction, be it tax-related or otherwise, unless specifically required by any applicable laws and/or regulations as reasonably
determined by Parties.  In the event that a withholding tax or tax deduction is required, the Assignee can make the payment
to the Assignor net of the withholding tax or tax deduction, subject to the following requirements under this Section.


 


(a) Both the
Assignee and the Assignor shall use commercially reasonable efforts to do all such things and acts and to sign all such documents
as will enable them to take advantage of any benefits under the applicable treaties or agreements between or otherwise recognized
by their respective jurisdiction.

(b) The Assignee
shall supply to the Assignor evidence to the reasonable satisfaction of the Assignor that the Assignee has accounted to the appropriate
governmental authorities for the tax withheld or deducted, and shall provide all such assistance as may be requested by the Assignor
in recovering, or otherwise obtaining any benefits on account of, the tax withheld or deducted. In particular, the Assignee shall
be responsible for obtaining a tax clearance certificate from appropriate governmental tax authorities and provide it to the Assignor
within 60 days after such taxes shall become due and payable.


 


(c) If the
Assignee intends to make a payment to the Assignor in accordance with Section 2.1(b)(“Second Payment”) and 2.4(“Shared
Revenue”), the Assignee will first notify Assignor of such intent and Assignor will notify Assignee within ten (10) business
days of whether the Assignee should or should not withhold or deduct any taxes. Assignee is deemed by this Agreement to have the
intent not to pay any withholding tax for the $4,000,000 First Payment set forth in Section 2.1(a), as appropriate notice to Assignor
for this Section’s purposes. If the Assignee, based on a foregoing notice of Assignor, makes a payment to Assignor without
withholding or deducting any taxes and a subsequent audit or other examination identifies that a withholding or deduction should
have been made from the payment, the Assignor shall be solely and exclusively liable to bear and settle with the appropriate governmental
authorities the taxes not withheld or deducted, along with any interest, penalties and other charges associated therewith the taxes
and determined based upon the taxes.


 


2.6Audit of
Records.  No more than once each calendar year and upon reasonable advance written notice, Assignor may have an independent
auditor audit the applicable records, at Assignor’s request and expense, to verify the accuracy of the calculations of shared
revenue due to Assignor under this Agreement. All such records shall be treated as confidential information by the independent
auditor and shall not be disclosed to Assignor except insofar as necessary to verify to Assignor the accuracy of Assignee’s
payments to Assignor. Any payment adjustments (whether due to under- or over-payments) shall be incorporated with the next quarterly
payment under this Agreement. Should any payment be underpaid by 5% or more, without reasonable explanation, then Assignee shall
pay the reasonable expense of such audit, if any, along with a late payment fee of interest on the under-payment amount at an annual
interest rate of * (*%) or the maximum interest rate permitted by law, whichever is lesser, paid with the next quarterly
payment due under this Agreement. Assignee shall preserve and maintain all such books and records required for audit for a period
of five (5) years after the calendar quarter for which the books and records apply.

obligation set forth in Section 2.1), and the agreements, rights, duties, and obligations between Assignor or its Affiliates and
its or their licensees, Assignee agrees to compel its successors in interest, assigns and exclusive licensees of each Transferred
Patent to abide by the terms of this Agreement.


 


6Representations
and Warranties


 


As of the Effective
Date of this Agreement, each Party represents and warrants to the other party that:


 


6.1It is a company
duly formed and validly existing under the laws of the jurisdiction of its formation and has the full corporate power and authority
to enter into, execute and deliver this Agreement and perform the obligations contained herein and it has obtained all necessary
consents, approvals, and/or other authorizations required to enter into this Agreement and to carry out its obligations hereunder;

6.2The execution
and delivery by such Party of this Agreement and the performance by such Party of its obligations contemplated in this Agreement
have been duly authorized by any necessary corporate or other action of such Party;


 


6.3Neither Party
has made any agreement with any third party which would entitle such third party to claim any fee, commission or reimbursement
of expenses from the other Party or any of its Affiliates as a result of such Party entering into this Agreement. That is, for
example, Assignee has not made an agreement that obligates Assignor to make any further payments to a third party as a result of
this Agreement beyond the obligations provided for in this Agreement.


 


As of the Effective
Date of this Agreement, Assignor makes the representations and warranties in Sections 6.4 through 6.8 to Assignee:


 


6.4Assignor owns
all right, title and interest to the Transferred Patents existing as of the Effective Date, including, without limitation, all
right, title and interest to sue for infringement of the Transferred Patents and has the right to make the assignments provided
in Section 3.


 


6.5To the Knowledge
of Assignor, all such Transferred Patents are free from all liens, claims, mortgages, security interests or other encumbrances,
or restrictions, except as listed on Exhibit C.


 


6.6Assignor is
responsible for the payment of all maintenance fees, annuities and other like fees for such Transferred Patents that having a due
date on or before the later of (i) the Closing Date and (ii) May 31, 2013, and Assignee shall be responsible for the payment of
all such fees due after such date above.


 


6.7To the Knowledge
of Assignor, except as listed on Exhibit C, there has been no litigation or suit filed and/or pending, or written assertion, (i)
by or against Assignor concerning the ownership, validity, registrability, enforceability or use of any Transferred Patents, or
(ii) contesting or challenging the ownership, validity, registrability or enforceability of Assignor’s right to use any Transferred
Patents. To the Knowledge of Assignor, except as listed on Exhibit C, none of the Transferred Patents has ever been found invalid,
unpatentable, or unenforceable for any reason in any administrative, arbitration, judicial or other proceeding, and Assignor has
no Knowledge of and has not received any notice or information of any kind from any source suggesting that the Transferred Patents
may be invalid, unpatentable, or unenforceable. None of the Transferred Patents has been or is currently involved in any reexamination,
reissue, interference proceeding, or any similar proceeding except as noted in Exhibit A, and no such proceedings are pending or
threatened. If any of the Transferred Patents are terminally disclaimed to another patent or patent application, all patents and
patent applications subject to such terminal disclaimer are included in this transaction. To the extent “small entity”
fees were paid to the United States Patent and Trademark Office for any Transferred Patent, such reduced fees were then appropriate
because the payor qualified to pay “small entity” fees at the time of such payment and specifically had not licensed
rights in any of the Transferred Patents to an entity that was not a “small entity.”

6.8To the Knowledge
of Assignor and after conducting a review of Assignor’s legal department database of patent license agreements with regard
to the Transferred Patents, Assignor has not executed a patent license agreement with any third parties which expressly granted
a patent license under any and/or or all Transferred Patents to any third party (the date indicated in parentheses next to each
such party is expiring date), nor agreed to grant any such license in the future, except as disclosed in Exhibit C. For the avoidance
of doubt the foregoing statements in this Section do not apply to (i) any mandatory license to any governmental authority or equivalent
entity implied under any applicable law, (ii) any agreement between the Assignor or one of its Affiliates and its or their direct
or indirect suppliers, customers or partners in connection with the supply, development, sale, license, or distribution, by or
on behalf of Assignor, of products, software, technology or services, (iii) any obligation described in Section 5.5.


 


6.9Except as expressly
set forth in this Section 6, the Parties acknowledge and understand that the Transferred Patents are being sold “AS IS”
in all respects and with all faults, and without warranties or representations of any kind, express or implied, with respect to
the Transferred Patents. Assignor does not represent or warrant that the Transferred Patents are or are not of any particular scope,
valid, enforceable, or infringed by any product, service or method. Assignor further does not represent or warrant that the subject
matter disclosed in the Transferred Patents does or does not infringe the patent rights of any patent owner.

7.1Notwithstanding
any provision to the contrary, Assignee shall indemnify and hold Assignor and its Affiliates harmless against all losses, costs
and expenses (including employee time and attorneys’ fees) arising from Assignee’s activities relating to defense,
enforcement or licensing of any Transferred Patents.


 


7.2EXCEPT IN THE
CASE OF ANY (1) BREACH OF CONFIDENTIALITY, OR (2) INTENTIONAL MISREPRESENTATION BY ANY PARTY:

concerning the Transferred Patents shall be treated as Confidential Information. The Parties shall strictly perform confidentiality
obligations specified in the Non-Disclosure Agreement entered into by the Parties on December 20, 2012 and the Common Interest
Agreement executed by the Parties together with this Agreement. Notwithstanding the foregoing provisions of this Section 8.2, nothing
in this Agreement restricts or limits Assignee’s or Assignor’s ability to disclose that Assignee is the owner of the

COMMON INTEREST AGREEMENT


 


THIS COMMON
INTEREST AGREEMENT ("Agreement") is entered into by and between Huawei Technologies Co., Ltd., a Chinese Corporation,
having offices at Administration Building Huawei Technologies Co., Ltd. Bantian Longgang District, Shenzhen 518129, P. R. China
(“Assignor”), and Inventergy, Inc., a Delaware corporation, having offices at 19925 Stevens Creek Boulevard, Suite
100, Cupertino, California, 95014 United States of America (“Assignee”) (Assignee and Assignor each a “Party”
and together the “Parties”).


 


1. Background.


 


Each of Inventergy and
Huawei have entered into a Patent Rights Assignment Agreement (PRA) in connection with certain patent and other intellectual property
rights of Inventergy and/or Huawei (the "Patent Rights," and matters related to the Patent Rights, the "Patent Matters").


 


The parties share a common
legal interest in upholding the validity and enforceability of the Transferred Patents for purposes of Assignee’s licensing
and enforcement activities.  The parties anticipate that Inventergy will enforce inherent rights of the Patent Rights against
third parties through licensing activities and possibly as well through litigation. The parties have agreed to treat their communications
and those of their counsel relating to the Patent Matters as protected by the common interest doctrine. Furtherance of the Patent
Matters requires the exchange of proprietary documents and information, the joint development of legal strategies and the exchange
of privileged information and attorney work product developed by the parties and their respective counsel.


 


2. Common Interest.


 


In furtherance of their
common interest, the parties may continue to cooperate with each other, to the extent permitted by law, and subject to each party's
discretion, to share information protected by the attorney-client privilege, the work product doctrine, or other applicable privilege
or immunity with respect to the Patent Matters.  Any counsel or consultant retained by a party or their counsel to assist
in the Patent Matters shall be bound by, and entitled to the benefits of this Agreement.  Subject to the PRA, upon further
agreed by parties in writing, the parties and their counsel may continue to exchange privileged and work product information, orally
and in writing, including, without limitation, factual analyses, mental impressions, legal memoranda, source materials, draft legal
documents, evidence of use materials, claims charts, prosecution history files and other information (hereinafter "Common
Interest Materials"). The sole purpose of the exchange of the Common Interest Materials is to support the parties’
common interest with respect to the enforcement for the Patent Matters. Any Common Interest Materials exchanged shall continue
to be protected under all applicable privileges and no such exchange shall constitute a waiver of any applicable privilege or protection.
Nothing in this Agreement requires a party to share information with the other party. Nothing in this Agreement shall constitute
nor cause any obligation or liability to Assignor.


 


 


 


 


 


 


 





*Please note parts of this Agreement are
designated with an asterisk which indicates that material has been omitted and filed separately with the Securities and Exchange
Commission pursuant to a request for confidential treatment.







 






    	 	Huawei Inventergy Confidential	 46 / 65



    	 



    

 


		CONFIDENTIAL
    TREATMENT REQUESTED	 



 


 


Unless otherwise expressly specified under
PRA or further agreed by parties in writing, Assignor and inventors of the Transferred Patents shall not be obligated to assist
in prosecution, maintenance, litigation or licensing of the Transferred Patents or to execute or have executed additional oaths,
declarations or any other assistance after the assignment date.


 


3. Nondisclosure.


 


The parties and their counsel
shall use the Common Interest Materials solely in connection with the Patent Matters and the furtherance of the purposes and interests
of the PRA, and shall take appropriate steps to protect the privileged and confidential nature of the Common Interest Material.
Each party shall notify the other of any request, order and/or directive to produce such privileged documents as soon as practicable
and shall consult with the other party as to the appropriate response. Following such consultation, neither party nor their respective
counsel shall produce privileged documents unless or until required by law as determined by the relevant party's counsel. Except
as herein provided, in the event that either party or its counsel is requested or required in the context of a litigation, governmental,
judicial or regulatory investigation or other similar proceedings (by oral questions, interrogatories, requests for information
or documents, subpoenas, civil investigative demands or similar process) to disclose any Common Interest Materials, the party or
its counsel shall assert all applicable privileges, as determined by its counsel, including, without limitation, the common interest
doctrine, and, as soon as practicable, shall inform the other party and the other party's counsel of the request or requirement
to disclose.


 


4. Relationship; Additions;
Termination.


 


This Agreement
does not by itself create any agency or similar relationship among the parties. Through the term of the agreement between the parties,
or any other agreement requiring confidentiality (whichever term is longer), neither party
nor their respective counsel has the authority to waive any applicable privilege or doctrine on behalf of the other party.


 


Nothing in this Agreement
affects the separate and independent representation of each party by its respective counsel or creates an attorney-client relationship
between the counsel for a party and the other party to this Agreement.


 


This Agreement shall continue
until terminated upon the written request of either party. Upon termination, each party and their respective counsel shall return
any Common Interest Material furnished by the other party, unless otherwise required by law or regulation. Notwithstanding termination,
this Agreement shall continue to protect all Common Interest Materials disclosed prior to termination, including under applicable
attorney client privileges and/or work product doctrine, and sections 3 and 5 shall survive termination of this Agreement.


 


5. General Terms.


 


This Agreement is governed
by the laws of the State of California, without regard to its choice of law principles to the contrary. In the event any provision
of the Agreement is held by any court of competent jurisdiction to be illegal, void or unenforceable, the remaining terms shall
remain in effect. Failure of either party to enforce any provision of this Agreement shall not be deemed a waiver of future enforcement
of that or any other provision.

Section 6.Rights,
Duties and Immunities of Escrow Agent. Acceptance by Escrow Agent of its duties under this Agreement is subject to the following
terms and conditions, which all parties to this Agreement hereby agree shall govern and control the rights, duties and immunities
of Escrow Agent.


 


(a)The

obligations shall be inferred or implied. Escrow Agent shall not be liable except for the performance of such duties and obligations
as are expressly and specifically set out in this Agreement. Escrow Agent shall not be liable for the accuracy of any calculations
made by any Escrow Party or the sufficiency of any funds for any purpose.


 


(b)Escrow
Agent shall not be required to expend or risk any of its own funds or otherwise incur any liability, financial or otherwise, in
the performance of any of its duties hereunder.


 


(c)Escrow
Agent is not a party to, and is not bound by, or required to comply with any agreement or other document out of which this Agreement
may arise. Escrow Agent shall not be required to inquire as to the performance or observation of any obligation, term or condition
under any other agreements or arrangements between the Escrow Parties. Escrow Agent shall be under no liability to any party hereto
by reason of any failure on the part of either Escrow Party or any maker, guarantor, endorser or other signatory of any document
or any other third party to perform, such party’s obligations under any such document. Except for amendments to this Agreement
referred to herein, and except for notifications or instructions to Escrow Agent under this Agreement, Escrow Agent shall not be
obliged to recognize or be chargeable with knowledge of any of the terms or conditions of any agreement between the Escrow Parties,
notwithstanding that references thereto may be made herein and whether or not it has knowledge thereof.


 


(d)Escrow
Agent shall not have any responsibility to determine the authenticity or validity of any notice, direction, instruction, instrument,
document or other items delivered to it by any party, or for the identity, authority or rights of persons executing or delivering
any such notice, direction, instruction, instrument, document, or other items delivered to it by such party or parties. Escrow
Agent is authorized to comply with and rely upon any notice, direction, instruction or other communication reasonably believed
by it to have been sent or given by either Escrow Party and, in the absence of willful misconduct or gross negligence, shall be
fully protected in acting in accordance with such written direction or instructions given to it under, or pursuant to, this Agreement.


 


(e)Escrow
Agent shall not be bound by any waiver, modification, termination or rescission of this Agreement or any of the terms hereof, unless
evidenced in writing and delivered to Escrow Agent signed by each party’s Authorized Representative and, if the duties or
rights of Escrow Agent are affected, unless it shall give its prior written consent thereto. No person, firm or corporation will
be recognized by Escrow Agent as a successor or assignee of either Escrow Party until there shall be presented to Escrow Agent
evidence satisfactory to it of such succession or assignment. This Agreement shall not be deemed to create a fiduciary relationship
among the parties hereto under state or federal law.

(f)If
at any time Escrow Agent is served with any judicial or administrative order, judgment, decree, writ or other form of judicial
or administrative process which in any way affects the Escrow Assigments (including but not limited to orders of attachment or
any other forms of levies or injunctions or stays relating to the transfer of the Escrow Assignments), Escrow Agent is authorized
to comply therewith in any manner as it or its legal counsel of its own choosing deems appropriate; and if Escrow Agent complies
with any such judicial or administrative order, judgment, decree, writ or other form of judicial or administrative process, Escrow
Agent shall not be liable to any of the parties hereto or to any other person or entity even though such order, judgment, decree,
writ or process may be subsequently modified or vacated or otherwise determined to have been without legal force or effect.


 


(g)Escrow
Agent shall not be liable for any action taken or omitted or for any loss or damage resulting from its actions or its performance
of its duties hereunder in the absence of gross negligence or willful misconduct on its part, provided that Escrow Agent acts in
accordance with this Agreement. In no event shall Escrow Agent be liable (i) for acting in accordance with or relying upon any
instruction, notice, demand, certificate or document from either Escrow Party, or any entity acting on behalf of either, (ii) for
any consequential, punitive or special damages, (iii) for the acts or omissions of its nominees, designees, subagents or subcustodians,
or (iv) for an amount in excess of the value of the Escrow Assignments, valued as of the date of loss.


 


(h)In
the event of any ambiguity or uncertainty hereunder or in any notice or other communication received by Escrow Agent hereunder,
Escrow Agent is hereby authorized by the Escrow Parties to refrain from taking any action other than to retain possession of the
Escrow Assignments, unless Escrow Agent receives written instructions, signed by an Authorized Representative of both Escrow Parties
which eliminates such ambiguity or uncertainty.


 


(i)Escrow
Agent may consult with legal counsel of its own choosing (the fees of which shall be indemnifiable expenses pursuant to Section
9) as to any matter relating to this Agreement and Escrow Agent shall incur no liability and shall be fully protected in respect
of any action taken, omitted or suffered by it in good faith in accordance with the advice or opinion of such counsel.


 


(j)In
the event of any dispute or conflicting claim with respect to the payment, ownership or right of possession of the Escrow Account,
Escrow Agent shall be entitled, in its sole discretion, to refuse to comply with any and all claims, demands or instructions. Escrow
Agent is authorized and directed to retain in its possession, without liability to anyone, except for its own gross negligence
or willful misconduct, all or any part of the Escrow Assignments until such dispute shall have been settled either by mutual agreement
of the parties concerned or by final order, decree or judgment of a court or other tribunal of competent jurisdiction in the United
States of America (as notified to Escrow Agent in writing by the parties to the dispute or their authorized representatives and
setting forth the resolution of the dispute). Escrow Agent shall be under no duty whatsoever to institute, defend or partake in
such proceedings. The rights of Escrow Agent under this paragraph are in addition to all other rights which it may have by law
or otherwise including, without limitation, the right to file an action in interpleader.

(k)Escrow
Agent shall not incur liability for not performing any act or not fulfilling any duty, obligation or responsibility hereunder by
reason of any occurrence beyond the foreseeable control of Escrow Agent (including but not limited to any act or provision of any
present or future law or regulation or governmental authority, any act of God or war, terrorism or the unavailability of the Federal
Reserve Bank or other wire or communication facility).


 


(l)When
Escrow Agent acts on any communication (including, but not limited to, communication with respect to the delivery of securities
or the wire transfer of funds) sent by electronic transmission, Escrow Agent, absent gross negligence or willful misconduct, shall
not be responsible or liable in the event such communication is not an authorized or authentic communication of the party involved
or is not in the form the party involved sent or intended to send (whether due to fraud, distortion or otherwise). Escrow Agent
shall not be liable for any losses, costs or expenses arising directly or indirectly from Escrow Agent’s reliance upon and
compliance with such instructions notwithstanding such instructions conflict or are inconsistent with a subsequent written instruction. 
Buyer or the Seller Escrow Party, as the case may be, absent gross negligence or willful misconduct, agrees to assume all risks
arising out of the use of such electronic transmission to submit instructions and directions to Escrow Agent, including without
limitation the risk of Escrow Agent acting on unauthorized instructions, and the risk or interception and misuse by third parties.
