other party than Assignor or Affiliates of Assignor. Assignor and Assignee intend for this license to be limited to the Assigned

sales volume that is equal to the sales of the Affiliate in question during the full calendar year immediately prior to the year
during which the Affiliate ceased to be an Affiliate, allowing * annual growth.

life of such applicable Sublicensable Patents or any shorter period, at Assignor’s sole discretion, and Assignor may grant
such sublicenses without a consent from or accounting to Assignor. If such a sublicense is granted to any of the Unlicensed Companies,
Assignor shall provide notice to Assignee within * (*) days of the sublicense grant; otherwise, Assignor has no obligation to provide
notice of a sublicense grant. Nothing in this Agreement shall imply or be construed as any obligation for Assignor to exploit such
right to grant sublicenses or to grant a sublicense to any person or entity. The Parties further agree that no laches, equitable
estoppel, or similar legal doctrine will apply to Assignee or Assignor as a result of Assignor’s action or inaction in the
exercise of such right. Assignor and Assignee intend for this right and any sublicenses granted under this right to be limited
to the applicable claims of the Sublicensable Patents, and Assignor expressly acknowledges that it excludes any rights under any
legal or equitable theory, including patent exhaustion, to any of the other Assigned Patents that are not Sublicensable Patents

and will not now or hereafter divulge any of this information thereof to any third party except (a) with the prior written consent
of the other Party; (b) as otherwise may be required by law or legal or administrative process, or pursuant to Generally Accepted

time if ten (10) days notice is not reasonably possible under the circumstances, written notice of such disclosure, if permitted
by law or administrative, accounting or legal process; and provided further that, in (e) above, to the extent permitted by law,
the Assignee will use all reasonable and legal means available to minimize the disclosure to third parties, including, without
limitation, seeking a confidential treatment request or protective order whenever appropriate or available.

EXHIBIT D – COMMON INTEREST
AGREEMENT 


 


THIS COMMON
INTEREST AGREEMENT ("Agreement") is entered into and effective as of _________, 20__ by and between Inventergy,
Inc., a Delaware corporation, having offices at 19925 Stevens Creek Boulevard, Suite 100, Cupertino, California, 95014 United States
of America (“Inventergy”) and Nokia Corporation, a Finnish  corporation having a principal place of business
at Karakaari 7, 02610 Espoo Finland (“Company”). (Inventergy and Company each a “Party” and together
the “Parties”).


 


1. Background.


 


Each of Inventergy and
Company have entered into a PATENT PURCHASE AGREEMENT (the “PPA”) having an effective date of __________, 20__ in connection
with certain patent rights acquired by Inventergy from Company and certain licenses retained under such patents by Company (the
"Patent Rights," and matters related to any of the Patent Rights, the "Patent Matters").


 


The Parties have a common
legal interest in upholding the validity and enforceability of the Patent Rights for purposes of enforcement. 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.


 


The Parties have a common,
joint and mutual legal interest in the monetization of valid and enforceable patents. In furtherance of that common interest, the
Parties will 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.


 


In order to further their
common interest, 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 of 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.

CONFIDENTIAL







 


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 PPA, 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 termination or expiration of PPA, or 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.

EXHIBIT F – LICENSING STATEMENT


 


Nokia
reaffirms licensing commitments for standard essential patents


08
April 2014


 


 


Over the last two decades,
Nokia has developed a large number of fundamental technologies and made significant contributions to the development of wireless
communication standards. This research and development investment has resulted in a significant portfolio of standard essential
patents (SEPs), which Nokia has agreed to license on fair, reasonable and non-discriminatory (FRAND) terms, in line with the intellectual
property rights policies of the relevant standard setting organizations.


 


To date, in line with those
undertakings, we have successfully agreed licenses with more than 60 companies, enabling them to benefit from our innovations to
build products that work to the standards, fostering increased competition and more choice for consumers. From time to time, Nokia
has shared information on the Nokia licensing program with competition or antitrust authorities in connection with specific cases
or investigations. No authority has ever requested Nokia to change the way Nokia licenses its SEPs.


 


After the pending acquisition
announced on September 3, 2013 of substantially all of Nokia’s Devices & Services business by Microsoft is closed, Nokia
will retain its world-leading patent portfolio and Nokia’s previous FRAND undertakings remain in force. In addition to other
customary closing conditions, the transaction with Microsoft is subject to regulatory approvals, a process which has involved thorough
review of Nokia’s licensing practices by several competition authorities around the world. During that process, no authority
has challenged Nokia’s compliance with its FRAND undertakings or requested that Nokia make changes to its licensing program
or royalty terms.


 


In connection with this
transaction with Microsoft, some of our competitors have suggested to regulators that after the transaction Nokia could try to
abuse its position as a strong SEP holder. As we have no intention to do so and plan to continue to honor our FRAND undertakings
in the future, we are prepared to voluntarily reaffirm Nokia’s continuing commitment to FRAND licensing principles.

Our statement below provides
clarity on how Nokia will continue to license its SEPs. It does not reflect or introduce any changes to Nokia’s existing
licensing program, royalty terms or practices. The statement has been provided to the Ministry of Commerce of the People’s
Republic of China, in order to facilitate the approval process for Microsoft’s acquisition of substantially all of Nokia’s
Devices & Services business. It applies equally to prospective licensees irrespective of their domicile.


 


		1.	Nokia confirms its continued commitment to honor its undertakings to standard-setting organizations
(SSOs) to license its standard-essential patents (SEPs) on (fair), reasonable and non-discriminatory (FRAND) terms pursuant to
IPR policies of such SSOs. This commitment prevents Nokia from imposing licensing terms for its SEPs that would be inconsistent
with such FRAND undertakings.



 


		2.	Nokia confirms its support for a principle that, subject to reciprocity, injunctions with SEPs
should not be enforced to prevent the implementation of a standard subject to FRAND undertakings, unless a patent holder has made
a FRAND license available and the prospective licensee has been unwilling to enter into such FRAND license or to comply with its
terms.



 


		3.	Subject to reciprocity and the evolution of SSO IPR policies and judicial interpretations thereof,
Nokia acknowledges that the willingness of a party without undue delay to submit the resolution of a possible dispute whether license
terms offered by Nokia are inconsistent with Nokia's FRAND undertakings to an independent adjudicator that is reasonably acceptable
to both parties, to be bound by such adjudication, to enter into FRAND license resulting from such adjudication, and to pay any
potential award and FRAND royalties resulting from such adjudication and agreement, can be a relevant factor for an enforcing body
to determine whether a party is a willing licensor or licensee.



 


		4.	Subject to reciprocity and Nokia’s FRAND undertakings to respective SSOs, Nokia makes its
SEPs covered under such undertakings available for licensing pursuant to the IPR policies of such SSOs without subjecting the availability
of such licenses to the licensees also taking licenses to Nokia’s patents not covered by such undertakings.

		5.	Whenever Nokia transfers SEPs to a new owner in the future, Nokia will pass on the FRAND undertakings
with respect to such SEPs to such new owner by only assigning such SEPs subject to the existing FRAND undertakings given by Nokia
to SSOs (including what is reconfirmed herein).



 


		6.	Nokia’s current practice of valuing each FRAND license in its full context takes into account,
without limitation, the patents or portfolios licensed, the term, the products licensed, the business model for selling or distributing
such products, the standards covered, the extent of market adoption of the standardized functionalities, the agreement structure,
the value of any grant back license or any other non-monetary compensation, payment arrangements, and the field of use that are
intended to be covered in each situation, as applicable. Following the closing of Microsoft transaction and subject to reciprocity,
Nokia will not depart from its currently generally offered FRAND per unit running royalty rates for Nokia’s current portfolios
of cellular communication SEPs, as and to the extent applicable, except where merited by differences in the above factors.



 


		7.	Only for the avoidance of doubt and without intention to allow circumvention of the commitments
made herein, nothing in these commitments is intended to (a) have any impact on Nokia’s rights or obligations beyond the
extent to which Nokia’s SEPs are covered by its existing FRAND undertakings, (b) limit Nokia’s legitimate right to
license or divest any of its patents, (c) amend or cause amendment of any contract between Nokia and any third party, or (d) create
any obligation for Nokia to take licenses to technologies that Nokia does not use.



 


		8.	Notwithstanding the foregoing, the commitment in paragraph 6 does not apply with respect to any
company that asserts any patents against Nokia’s manufacture, sale or offering of mobile communication products or services.

FORWARD-LOOKING
STATEMENTS


It should be noted that
Nokia and its business are exposed to various risks and uncertainties and certain statements herein that are not historical facts
are forward-looking statements, including, without limitation, those regarding: A) the planned sale by Nokia of substantially all
of Nokia's Devices & Services business, including Smart Devices and Mobile Phones (referred to below as "Sale of the D&S
Business") pursuant to the Stock and Asset Purchase Agreement, dated as of September 2, 2013, between Nokia and Microsoft
International Holdings B.V.(referred to below as the "Agreement"); B) the closing of the Sale of the D&S Business;
C) receiving timely, if at all, necessary regulatory approvals for the Sale of the D&S Business; D) expectations, plans or
benefits related to or caused by the Sale of the D&S Business; E) expectations, plans or benefits related to Nokia's strategies,
including plans for Nokia with respect to its continuing businesses that will not be divested in connection with the Sale of the
D&S Business; F) expectations, plans or benefits related to changes in leadership and operational structure; G) expectations
and targets regarding our operational priorities, financial performance or position, results of operations and use of proceeds
from the Sale of the D&S Business; and H) statements preceded by "believe," "expect," "anticipate,"
"foresee," "sees," "target," "estimate," "designed," "aim", "plans,"
"intends," "focus," "will" or similar expressions. These statements are based on management's best
assumptions and beliefs in light of the information currently available to it. Because they involve risks and uncertainties, actual
results may differ materially from the results that we currently expect. Factors, including risks and uncertainties that could
cause these differences include, but are not limited to: 1) the inability to close the Sale of the D&S Business in a timely
manner, or at all, for instance due to the inability or delays in obtaining necessary regulatory approvals for the Sale of the
D&S Business, or the occurrence of any event, change or other circumstance that could give rise to the termination of the Agreement;
2) the potential adverse effect on the sales of our mobile devices, business relationships, operating results and business generally
resulting from the announcement of the Sale of the D&S Business or from the terms that we have agreed for the Sale of the D&S
Business; 3) any negative effect from the implementation of the Sale of the D&S Business, as we may forego other competitive
alternatives for strategies or partnerships that would benefit our Devices & Services business and if the Sale of the D&S
Business is not closed, we may have limited options to continue the Devices & Services business or enter into another transaction
on terms favorable to us, or at all; 4) our ability to effectively and smoothly implement planned changes to our leadership and
operational structure or maintain an efficient interim governance structure and preserve or hire key personnel; 5) any negative
effect from the implementation of the Sale of the D&S Business, including our internal reorganization in connection therewith,
which will require significant time, attention and resources of our senior management and others within the company potentially
diverting their attention from other aspects of our business; 6) disruption and dissatisfaction among employees caused by the plans
and implementation of the Sale of the D&S Business reducing focus and productivity in areas of our business; 7) the amount
of the costs, fees, expenses and charges related to or triggered by the Sale of the D&S Business; 8) any impairments or charges
to carrying values of assets or liabilities related to or triggered by the Sale of the D&S Business; 9) potential adverse effects
on our business, properties or operations caused by us implementing the Sale of the D&S Business; 10) the initiation or outcome
of any legal proceedings, regulatory proceedings or enforcement matters that may be instituted against us relating to the Sale
of the D&S Business, as well as the risk factors specified on pages 12-47 of Nokia's annual report on Form 20-F for the year
ended December 31, 2012 under Item 3D. "Risk Factors." and risks outlined in our fourth quarter and full year 2013 results
report available for instance at www.nokia.com/financials. Other unknown or unpredictable factors or underlying assumptions subsequently
proving to be incorrect could cause actual results to differ materially from those in the forward-looking statements. Nokia does
not undertake any obligation to publicly update or revise forward-looking statements, whether as a result of new information, future
events or otherwise, except to the extent legally required.
