FOR VALUE RECEIVED, AIR INDUSTRIES

assigns (the “Holder”), without demand, the sum of__________ Dollars ($ ), together with accrued interest
on the unpaid principal amount thereof, on December 31, 2020 (the “Maturity Date”), or such earlier date as the
same may become due as provided in Section 3 hereof.

 

Interest on the unpaid principal amount
of this Note shall accrue and shall be paid on the Maturity Date or, at the option of the Holder, upon conversion of this Note
into shares of Common Stock as provided below. If interest is paid in cash, it will accrue and be paid at the rate of six percent

is payable.

 

This Note is one of a series of the Company’s
6% subordinated convertible notes due December 31, 2020 (together with any other Notes issued as contemplated by this Note, the
“Notes”) issued upon amendment of previously outstanding 8% Subordinated Convertible Notes of the Company.

 

This Note may be prepaid in whole or in
part at any time but only with the prior consent of the Holder. All payments made pursuant to this Note shall be applied first
to reimbursable expenses, interest accrued, if any, and then principal.

 

The following is a statement of rights
of the Holder and the conditions to which this Note is subject, and to which the Holder, by acceptance of this Note, agrees:

 

1. Subordination. (a) This
Note will be subordinate and inferior to the Company’s Senior Indebtedness (as hereinafter defmed). The Company for
itself, its successors and assigns, covenants and agrees and the Holder of this Note, for himself, his successors and
assigns, by his acceptance of this Note likewise covenants and agrees that, to the extent provided below, the payment of all
amounts due pursuant to this Note is hereby expressly subordinated and junior in right of payment to the extent and in the
manner hereinafter set forth, to the Company’s Senior Indebtedness. As used herein, the term “Senior
Indebtedness” shall mean the principal of, and interest and premium, if any, on any and all, (i) indebtedness of the
Company for borrowed money or obligations with respect to which the Company is a guarantor, to banks, insurance companies, or
other financial institutions or entities regularly engaged in the business of lending money, in each case as in effect as of
the date hereof (other than the Notes), or as may be borrowed hereafter, including without limitation, indebtedness incurred
by one or more of the Company’s subsidiaries under the Amended and Restated Revolving Credit, Term Loan, Equipment Line
and Security Agreement, dated as of June 27, 2013 among Air Industries Machining, Corp., Welding Metallurgy, Inc., Nassau
Tool Works, Inc., Woodbine Products Inc., Eur-Pac Corporation, Electronic Connection Corporation, The Sterling Engineering
Corporation, and PNC Bank, National Association, as agent for the various lenders named therein, as amended as of the date
hereof (the “Loan Agreement”), the payment of which has been guaranteed by the Company and Air Realty Group, LLC
(the “Guarantors”), (ii) any such indebtedness or any debentures, notes or other evidence of indebtedness issued
in exchange for or to refinance such Senior Indebtedness, or any indebtedness arising from the satisfaction of such Senior
Indebtedness by a Guarantor, provided that such indebtedness issued in exchange for or to refinance Senior Indebtedness or
arising from the satisfaction of Senior Indebtedness by a Guarantor is on commercially reasonable terms as of the date of
incurrence not to exceed the principal amount under such Senior Indebtedness and provided further that the Company provides
the Holder with prior written notice of such action.

 

    	 	 	 

     

    

 

(b) Upon the acceleration
of any Senior Indebtedness or upon the maturity of all or any portion of the principal amount of any Senior Indebtedness by lapse
of time, acceleration or otherwise, all such Senior Indebtedness which has been so accelerated or matured shall first indefeasibly
be paid in full before any payment is made by the Company or any person acting on behalf of the Company on account of any obligations
evidenced by this Note.

 

(c) The
Company shall not pay any principal portion of this Note, or interest accrued hereon, if at such time there exists a Blockage Event
(as hereafter defined) and written notice thereof has been given to the Company and the Holder by the holders of the Senior Indebtedness.

 

(d) A
“Blockage Event” is deemed to exist for the period of time commencing on the date of receipt by the Company of written
notice of the occurrence of a Default or an Event of Default (as defined in the instruments evidencing the Senior Indebtedness),
provided that the failure to pay accrued interest on this Note or the other Notes when due shall not give rise to a Blockage Event
in the absence of another Default or Event of Default, which notice shall specify such Default or Event of Default, and ending
on:

 

(i) the
date such Default or Event of Default under the Senior Indebtedness, as applicable, is cured or waived, provided that such Default
or Event of Default is the result of the failure to pay any amount due thereunder; or

 

( ) in
the case of any other Default or Event of Default under the Senior Indebtedness, the earlier of (A) the date on which Holder has
received written notice of such Default or Event of Default shall have been cured or waived and (B) the date that is 365 days after
the occurrence of such Default or Event of Default, provided that a Blockage Event with respect to a single specified Default or
Event of Default may be deemed to occur only once for each twelve-month period, provided, further, that no Default or Event of
Default that existed at the commencement of, or during the pendency of, a Blockage Event shall serve as the basis for the institution
of any subsequent Blockage Event.

 

A Blockage Event shall not be deemed to
have existed during the period of time commencing on the date upon which the holder of this Note or holders of other Notes accelerate
payment of the principal amount of this Note or such other Notes as a result of any Event of Default hereunder or under such other
Notes and ending on the 365th day after written notice of such acceleration given by the holder or such other holders
to the Company and the holders of the instruments evidencing the Senior Indebtedness; provided that in no event shall the Company
pay the holder of this Note or the holders of any other Notes the principal amount so accelerated if a Blockage Event then exists
until the Senior Indebtedness has been paid in full.

 

(e) At any time
there exists a Blockage Event, (i) the Company shall not, directly or indirectly, make any payment of any part of this Note,
(ii) the Holder shall not demand or accept from the Company or any other person any such payment or cancel, set-off or
otherwise discharge any part of the indebtedness represented by this Note, and (iii) neither the Company nor the Holder shall
otherwise take or permit any action prejudicial to or inconsistent with the priority position of any holder of Senior
Indebtedness over the Holder of this Note.

 

(f) No right of
any holder of Senior Indebtedness to enforce the subordination provisions of this obligation shall be impaired by any act or
failure to act by the Company or the Holder or by their failure to comply with this Note or any other agreement or document
evidencing, related to or securing the obligations hereunder. Without in any way limiting the generality of the preceding
sentence, the holders of Senior Indebtedness may, at any time and from time to time, without the consent of or notice to the
Holder, without incurring responsibility to the Holder and without impairing or releasing the subordination provided in this
Note or the obligations of the Holder to the holders of Senior Indebtedness, do any one or more of the following: (i) change
the manner, place or terms of payment of any Senior Indebtedness provided that such change does not materially impact Holder
in an adverse manner; (ii) sell, exchange, release or otherwise deal with any property pledged, mortgaged or otherwise
securing any Senior Indebtedness; (iii) release any person or entity liable in any manner for the collection of any Senior
Indebtedness; and (iv) exercise or refrain from exercising any rights against the Company or any other person or entity.

 

    	 	2	 

     

    

 

(g) In
the event that the Company shall make any payment or prepayment to the Holder on account of the obligations under this Note which
is prohibited by this Section, such payment shall be held by the Holder, in trust for the benefit of, and shall be paid forthwith
over and delivered to, the holders of Senior Indebtedness (pro rata as to each of such holders on the basis of the respective amounts
and priorities of Senior Indebtedness held by them) to the extent necessary to pay all Senior Indebtedness due to such holders
of Senior Indebtedness in full in accordance with its terms (whether or not such Senior Indebtedness is due and owing), after giving
effect to any concurrent payment or distribution to or for the holders of such Senior Indebtedness.

 

(h) After
all Senior Indebtedness indefeasibly is paid in full and until the obligations under the Note are paid in full, the Holder shall
be subrogated to the rights of holders of Senior Indebtedness to the extent that distributions otherwise payable to the Holder
have been applied to the payment of Senior Indebtedness. For purposes of such subrogation, no payments or distributions to holders
of such Senior Indebtedness of any cash, property or securities to which the Holder would be entitled except for the provisions
of this Section and no payment over pursuant to the provisions of this Section to holders of such Senior Indebtedness by the Holder,
shall, as between the Company, its creditors other than holders of such Senior Indebtedness, and the Holder, be deemed to be a
payment by the Company to or on account of such Senior Indebtedness, it being understood that the provisions of this Section are
solely for the purpose of defining the relative rights of the holders of such Senior Indebtedness, on the one hand and the Holder,
on the other hand.

 

(i) In
any insolvency, receivership, bankruptcy, dissolution, liquidation or reorganization proceeding, or in any other proceeding, whether
voluntary or involuntary, by or against the Company under any bankruptcy or insolvency law or laws relating to relief of debtors,
to compositions, extensions or readjustments of indebtedness:

 

(i) the
claims of any holders of Senior Indebtedness against the Company shall be paid indefeasibly in full in cash or such payment shall
have been provided for in a manner acceptable to the holders of at least a majority of the then outstanding principal amount of
the Senior Indebtedness before any payment is made to the Holder;

 

(ii) until
all Senior Indebtedness is indefeasibly paid in full in cash or such payment shall have been provided for in a manner acceptable
to the holders of at least a majority of the then outstanding principal amount of the Senior Indebtedness before any payment is
made to the Holder, any distribution to which the Holder would be entitled but for this Section shall be made to holders of Senior
Indebtedness, except for distribution of securities issued by the Company which are subordinate and junior in right of payment
to the Senior Indebtedness; and

 

(iii) holders
of Senior Indebtedness shall have the right to enforce, collect and receive every such payment or distribution and give acquittance
therefor. If, in or as a result of any action, case or proceeding under Title 11 of the United States Code, as amended from time
to time, or any comparable statute, relating to the Company, the holders of the Senior Indebtedness return, refund or repay to
the Company, or any trustee or committee appointed in such case or proceeding receive any payment or proceeds of any collateral
in connection with such action, case or proceeding alleging that the receipt of such payments or proceeds by the holders of the
Senior Indebtedness was a transfer voidable under state or federal law, then the holders of the Senior Indebtedness shall not be
deemed ever to have received such payments or proceeds for purposes of this Note in determining whether and when all Senior Indebtedness
has been paid in full and the Company shall pay or cause to be paid, and the Holder shall be entitled to receive any such funds,
proceeds or collateral to satisfy all amounts due hereunder. In the event the holders of Senior Indebtedness receive amounts in
excess of payment in full (cash) of amounts outstanding in respect of Senior Indebtedness (without giving effect to whether claims
in respect of the Senior Indebtedness are allowed in any insolvency proceeding), the holders of Senior Indebtedness shall pay such
excess amounts to the Holder.

 

(k) By
its acceptance of this Note, the Holder agrees to execute and deliver such documents as may be reasonably requested from time to
time by the Company or the holder of any Senior Indebtedness in order to implement the foregoing provisions of this Section.

2. Conversion
At the Option of the Holder.

 

(a) (1) The
Holder shall have the option at any time while this Note remains outstanding to convert the unpaid principal amount and
accrued interest thereon into shares of the Company’s Common Stock at a conversion price of One Dollar and Fifty Cents
($1.50) per share, subject to adjustment as provided in Section 2(c) below (the “Conversion Price”). The number
of shares of Common Stock issuable upon any conversion of this Note shall equal the outstanding principal amount of this Note
to be converted, plus the amount of any accrued but unpaid interest on this Note through the date (the “Conversion
Date”) the Company receives a notice of conversion in the form of Schedule I annexed hereto (a “Conversion
Notice”), divided by the Conversion Price on the Conversion Date. The Holder shall effect conversions under this
Section 2(a)(1) by delivering to the Company a Conversion Notice, together with a schedule in the form of Schedule II annexed
hereto (the “Conversion Schedule”). If the Holder is converting less than all of the principal amount of this
Note, the Company shall promptly deliver to the Holder a Conversion Schedule indicating the principal amount (and accrued
interest) which has not been converted.

 

(2) Upon
conversion of this Note, the Company shall promptly (but in no event later than three (3) trading days after the Conversion Date)
issue or cause to be issued and cause to be delivered to or upon the written order of the Holder and in such name or names as the
Holder may designate a certificate for the shares of Common Stock issuable upon such conversion (the “Conversion Shares”).
The Holder, or any person so designated by the Holder to receive the Conversion Shares, shall be deemed to have become holder of
record of such Conversion Shares as of the Conversion Date. The Company shall, upon request of the Holder, use its reasonable best
efforts to deliver the Conversion Shares electronically through DTC.

 

(0) The
Holder shall not be required to deliver the original Note in order to effect a conversion hereunder. Execution and delivery of
the Conversion Notice shall have the same effect as cancellation of the original Note and issuance of a new Note representing the
remaining outstanding principal amount; provided that the cancellation of the original Note shall not be deemed effective
until a certificate for the Conversion Shares is delivered to the Holder, or the Holder or its designee receives a credit for the
Conversion Shares to its balance account with DTC through its Deposit Withdrawal Agent Commission System. The Holder shall deliver
the original Note to the Company within thirty (30) days after the conversion of the entire Note hereunder, provided, that
the Holder’s failure to so deliver the original Note shall not affect the validity of such conversion or any of the Company’s
obligations under this Note, and the Company’s sole remedy for the Holder’s failure to deliver the original Note shall
be to obtain an affidavit of lost Note from the Holder.

 

(0) The
Company’s obligations to issue and deliver Conversion Shares upon conversion of this Note in accordance with the terms and
subject to the conditions hereof are absolute and unconditional, irrespective of any action or inaction by the Holder to enforce
the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against any person or any action
to enforce the same, or any set-off, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by the
Holder or any other person of any obligation to the Company or any violation or alleged violation of law by the Holder or any other
person, and irrespective of any other circumstance which might otherwise limit such obligation of the Company to the Holder in
connection with the issuance of such Conversion Shares (other than such limitations contemplated by this Note).

 

(0) If
by the fifth (5d1) trading day after a Conversion Date the Company fails to deliver or cause to be delivered to the
Holder such Conversion Shares in such amounts and in the manner required pursuant to Section 2(a)(2), then the Holder will have
the right to rescind such conversion.

 

(1) If by the
third (3”) trading day after a Conversion Date the Company fails to deliver or cause to be delivered to the
Holder such Conversion Shares in such amounts and in the manner required pursuant to Section 2(a)(2), and if after such third
(3rd) trading day the holder purchases (in an open market transaction or otherwise) shares of common stock to deliver in
satisfaction of a sale by the holder of the Conversion Shares which the Holder anticipated receiving upon such conversion (a
“buy-in”), then the Company shall, at the option of the Holder (in his or its sole discretion), either (i) pay
cash to the Holder (in addition to any other remedies available to or elected by the Holder) in an amount equal to the
Holder’s total purchase price (including brokerage commissions, if any) for the shares of common stock so purchased
(the “buy-in price”), at which point the Company’s obligation to deliver such certificate (and to issue
such common stock) shall terminate, or (ii) promptly honor its obligation to deliver to the Holder a certificate or
certificates representing such common stock and pay cash to the holder in an amount equal to the excess (if any) of the
buy-in price over the product of (a) such number of shares of common stock, times (b) the closing price on the date of the
event giving rise to the Company’s obligation to deliver such certificate.

 

    	 	4	 

     

    

 

(7) Each certificate for Conversion Shares
shall bear a restrictive legend and any certificate issued at any time in exchange or substitution for any certificate bearing
such legend, shall also bear such legend.

 

(b) No
Fractional Shares. No fractional shares or scrip representing fractional shares shall be issued upon the conversion of this
Note. As to any fraction of a share which a Holder would otherwise be entitled to purchase upon such conversion, the Company shall
at its election, either pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied
by the volume weighted average price on the Conversion Date or round up to the next whole share.

 

(c) Adjustments
to Conversion Price. The Conversion Price is subject to adjustment from time to time as set forth in this Section 2(c).

 

(1) Stock
Dividends and Splits. If the Company, at any time while this Note is outstanding, (i) pays a stock dividend on its Common Stock
or otherwise makes a distribution of Common Stock on its Common Stock, (ii) subdivides outstanding shares of Common Stock into
a larger number of shares, or (iii) combines outstanding shares of Common Stock into a smaller number of shares, then in each such
case the Conversion Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock
outstanding immediately before such event and of which the denominator shall be the number of shares of Common Stock outstanding
immediately after such event. Any adjustment made pursuant to clause (i) of this Section shall become effective immediately after
the record date for the determination of stockholders entitled to receive such dividend or distribution, and any adjustment pursuant
to clause (ii) or (iii) of this Section shall become effective immediately after the effective date of such subdivision or combination.

 

(2) Pro
Rata Distributions. If the Company, at any time while this Note is outstanding, distributes to all holders of Common Stock
(i) evidences of its indebtedness, (ii) any security (other than a distribution of Common Stock described in Section 2(c)(1)(i)),
(iii) rights or warrants to subscribe for or purchase any security, or (iv) cash or any other asset (in each case, “Distributed
Property”), then the Company shall deliver to the Holder (on the effective date of such distribution), the Distributed Property
that the Holder would have been entitled to receive in respect of the Conversion Shares for which this Note could have been converted
immediately prior to the date on which holders of Common Stock became entitled to receive such Distributed Property.

 

(3) Fundamental
Changes. If, at any time while this Note is outstanding, (i) the Company, directly or indirectly, in one or more related
transactions effects any merger or consolidation of the Company with or into another Person, (ii) the Company, directly or
indirectly, effects any sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially
all of its assets in one or a series of related transactions, (iii) any, direct or indirect, purchase offer, tender offer or
exchange offer (whether by the Company or another Person) is completed pursuant to which holders of Common Stock are
permitted to sell, tender or exchange their shares for other securities, cash or property and has been accepted by the
holders of 50% or more of the outstanding Common Stock, (iv) the Company, directly or indirectly, in one or more related
transactions effects any reclassification, reorganization or recapitalization of the Common Stock or any compulsory share
exchange pursuant to which the Common Stock is effectively converted into or exchanged for other securities, cash or
property, or (v) the Company, directly or indirectly, in one or more related transactions consummates a stock or share
purchase agreement or other business combination (including, without limitation, a reorganization, recapitalization, spin-off
or scheme of arrangement) with another Person or group of Persons whereby such other Person or group acquires more than 50%
of the outstanding shares of Common Stock (not including any shares of Common Stock held by the other Person or other Persons
making or party to, or associated or affiliated with the other Persons making or party to, such stock or share purchase
agreement or other business combination) (each a “Fundamental Transaction”), then, upon any subsequent
conversion of this Note, the Holder shall have the right to receive, for each share of Common Stock that would have been
issuable upon such conversion immediately prior to the occurrence of such Fundamental Transaction, at the option of the
Holder, the number of shares of Common Stock of the successor or acquiring corporation or of the Company, if it is the
surviving corporation, and any additional consideration (the “Alternate Consideration”) receivable as a result of
such Fundamental Transaction by a holder of the number of shares of Common Stock into which this Note may be converted
immediately prior to such Fundamental Transaction. For purposes of any such conversion, the determination of the Conversion
Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration
issuable in respect of one share of Common Stock in such Fundamental Transaction, and the Company shall apportion the
Conversion Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different
components of the Alternate Consideration. If holders of Common Stock are given any choice as to the securities, cash or
property to be received in a Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate
Consideration it receives upon any conversion of this Note following such Fundamental Transaction. The Company shall cause
any successor entity in a Fundamental Transaction in which the Company is not the survivor (the “Successor
Entity”) to assume in writing all of the obligations of the Company under this Note and the other Transaction
Documents in accordance with the provisions of this Section pursuant to written agreements in form and substance reasonably
satisfactory to the Holder and approved by the Holder (without unreasonable delay) prior to such Fundamental Transaction and
shall, at the option of the Holder, deliver to the Holder in exchange for this Note a security of the Successor Entity
evidenced by a written instrument substantially similar in form and substance to this Note which is convertible into a
corresponding number of shares of capital stock of such Successor Entity (or its parent entity) equivalent to the shares of
Common Stock acquirable and receivable upon conversion of this Note (without regard to any limitations on the conversion of
this Note) prior to such Fundamental Transaction, and with conversion price which applies the conversion price hereunder to
such shares of capital stock (but taking into account the relative value of the shares of Common Stock pursuant to such
Fundamental Transaction and the value of such shares of capital stock, such number of shares of capital stock and such
exercise price being for the purpose of protecting the economic value of this Note immediately prior to the consummation of
such Fundamental Transaction), and which is reasonably satisfactory in form and substance to the Holder. Upon the occurrence
of any such Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after
the date of such Fundamental Transaction, the provisions of this Note and the other Transaction Documents referring to the
“Company” shall refer instead to the Successor Entity), and may exercise every right and power of the Company and
shall assume all of the obligations of the Company under this Note and the other Transaction Documents with the same effect
as if such Successor Entity had been named as the Company herein.

account of the Company, and the disposition of any such shares shall be considered an issue or sale of Common Stock.

 

(5) Notice
of Adjustments. Upon the occurrence of each adjustment pursuant to this Section 2(c), the Company at its expense will promptly
compute such adjustment in accordance with the terms hereof and prepare and deliver to the Holder a certificate describing in reasonable
detail such adjustment and the transactions giving rise thereto, including all facts upon which such adjustment is based.

capital stock of the Company, (ii) authorizes or approves, enters into any agreement contemplating or solicits stockholder approval
for a Fundamental Change or (iii) authorizes the voluntary dissolution, liquidation or winding up of the affairs of the Company,
then the Company shall deliver to the holders of the Notes a notice describing the material terms and conditions of such transaction,
at least twenty (20) trading days prior to the applicable record or effective date on which a Person would need to hold Common
Stock in order to participate in or vote with respect to such transaction, and the Company will take all steps reasonably necessary
in order to ensure that the holders of the Notes are given the practical opportunity to convert the Notes prior to such time so
as to participate in or vote with respect to such transaction.

ADDENDUM TO

ASSET EXCHANGE AGREEMENT

 

THIS ADDENDUM TO ASSET
EXCHANGE AGREEMENT (this “Addendum”) is made as of this 3rd day of October, 2018 (the “Effective Date”),
by and among C Media Limited, a corporation organized under the laws of the Cayman Islands (“C Media”), Luokung
Technology Corp., a corporation organized under the laws of the British Virgin Islands and formerly known as Kingtone Wirelessinfo
Solution Holding Ltd. (“Luokung”), and Topsky Info-tech Holdings Pte Ltd., a corporation organized under the
laws of Singapore (“Topsky”). C Media, Luokung and Topsky are sometimes referred to herein individually as a
“Party” and collectively as the “Parties”. Capitalized terms in this Addendum that are not
otherwise defined have the meanings given those terms in the Agreement (as defined below).

 

WHEREAS, C Media and
Luokung are party to that certain Asset Exchange Agreement, dated January 25, 2018 (the “Agreement”), pursuant
to which the Parties agreed to exchange substantially all of their assets through the exchange of the equity interests in the Parties’
wholly-owned subsidiaries (the “Asset Exchange”);

 

WHEREAS, the Parties
executed that Closing Acknowledgment, dated August 17, 2018 (the “Acknowledgement”), whereby the Parties acknowledged
the fulfillment or waiver of all conditions to the closing of the Asset Exchange (the “Exchange Closing”); and

 

WHEREAS, as of the
date hereof, Luokung has not completed the transfer of the issued and outstanding equity interests of Topsky, its wholly-owned
subsidiary (the “Topsky Interests”), to C Media as contemplated by the Agreement, and Luokung desires to retain
the Topsky Interests but complete the transfer to C Media of all the issued and outstanding equity interests of Xi’an Softech
Co., Ltd. (“Xi’an Softech”), a wholly-owned subsidiary of Topsky, together with all equity and contractual
ownership interests of the subsidiaries and contractually-controlled entities of Xi’an Softech (collectively, the “Softech
Interests”), and C Media desires that Luokung retain the Topsky Interests and complete the transfer of the Softech Interests,
under the terms and subject to the conditions described in the Agreement and herein.

 

NOW, THEREFORE, in
consideration of the mutual promises contained herein, the parties agree as follows:

 

1. Retained
Assets. Luokung and C Media hereby agree that the Softech Interests shall be transferred to C Media in accordance with the
Agreement, and that Luokung shall retain the Topsky Interests in consideration for the payment by Luokung of all expenses associated
with the transfer of the Softech Interests to C Media and assume the rights and obligations of Softech or its subsidiaries or contractually-controlled
entities in and to all contracts and agreements incorporating or using the Intellectual Property (as defined below).

 

2. Intellectual
Property. Luokung confirms that Topsky has the ownership of, or exclusive rights to, all of the intellectual property assets
and rights listed on Schedule 1 hereto (the “Intellectual Property”). For the avoidance of doubt, immediately
following the consummation of the transactions contemplated by this Addendum (the “Closing”), (i) Topsky shall
have the ownership of, or exclusive rights to, all the Intellectual Property, (ii) Luokung shall have retained the Topsky Interests,
and (iii) C Media shall hold the Softech Interests.

 

     

     

    

 

3. Assumption
of Contracts. In connection with Luokung’s retention of the Topsky Interests, the parties agree that Topsky shall retain
all of the rights, title and interests held by Softech or any of its subsidiaries or contractually-controlled entities in and to
all contracts and agreements incorporating or using the Intellectual Property (collectively, the “Contracts”),
and Topsky hereby accepts the obligations under the Contracts, and agrees to observe and perform all of the duties, obligations,
terms, provisions and covenants, and to pay and discharge all of the liabilities of Softech or any of its subsidiaries or contractually-controlled
entities to be observed, performed, paid or discharged under the Contracts.

 

4. Commercially
Reasonable Efforts. Subject to the terms and conditions herein provided, each of the Parties hereto shall use commercially
reasonable efforts to take, or cause to be taken, all actions, and to do, or cause to be done, all things reasonably necessary,
proper or advisable under applicable laws, rules and regulations to consummate and make effective the transactions contemplated
by this Addendum. In the event that at any time after the Closing any further action is necessary to carry out the purposes of
this Addendum, including without limitation obtaining any necessary assignments, consents or approvals, the Parties shall take
all such actions without any further consideration therefore.

 

5. Incorporated
by Reference. Except as specifically described herein, this Addendum is made subject to the terms of the Agreement, which terms
are incorporated herein by this reference, and each Party acknowledges and agrees that the representations, warranties, covenants,
agreements and indemnities contained in the Agreement shall remain in full force and effect to the full extent provided therein.
In the event of a conflict between the terms and conditions of this Addendum and the terms and conditions of the Agreement, the
terms and conditions of this Addendum shall prevail. If any provision of this Addendum, or the application of such provision to
any person or circumstance, shall be held invalid, illegal or unenforceable in any respect by a court of competent jurisdiction,
such invalidity, illegality or unenforceability shall not affect any other provision hereof.

 

6. Counterparts.
This Addendum may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together
shall constitute one and the same instrument.

 

7. Governing
Law; Jurisdiction. All questions concerning the construction, validity, enforcement and interpretation of the Addendum shall
be governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the
principles of conflicts of law thereof. Each Party agrees that all legal Actions concerning the interpretations, enforcement and
defense of the transactions contemplated by this Addendum (whether brought against a party hereto or its respective affiliates,
directors, officers, shareholders, partners, members, employees or agents) shall be commenced exclusively in the state and federal
courts sitting in the City of New York. Each Party hereby irrevocably submits to the exclusive jurisdiction of the state and federal
courts sitting in the City of New York, Borough of Manhattan for the adjudication of any dispute hereunder or in connection herewith
or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any
Action, any claim that it is not personally subject to the jurisdiction of any such court, that such Action is improper or is an
inconvenient venue for such Action. Each Party hereby irrevocably waives personal service of process and consents to process being
served in any such Action by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery)
to such party at the address in effect for notices to it under this Addendum and agrees that such service shall constitute good
and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to
serve process in any other manner permitted by law.
