PROMISSORY NOTE


 


	US $15,000,000	October
19, 2015


 


FOR VALUE
RECEIVED, Wave Sync Corp., a Delaware corporation (the “Company”), promises to pay to Jie Yang (the “Holder”),
the principal sum of Fifteen Million DOLLARS ($15,000,000) (the “Principal”) in lawful money of the United States
of America, without interest.  The principal amount hereof shall be paid in full to the Holder on the two (2) year anniversary
of the date hereof (the “Maturity Date”).


 


Capitalized
terms used herein but not defined herein shall have the meaning ascribed to it in that certain Share Purchase Agreement, dated
of even date herewith (the “SPA”), pursuant to which the Holder is acquiring this Note.


 


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


 


1.           Principal
Repayment.  The outstanding principal amount of this Note shall be payable on the Maturity Date, without interest,
unless this Note has been earlier converted as described below.


 


2.           Ranking.   Except
for the indebtedness of the Company and its Subsidiaries in existence on the date hereof as described in the SPA (including the
financial statements that form a part thereof), and subject to the terms and conditions of this Note, the obligations of the Company
under this Note shall rank senior with respect to all existing indebtedness of the Company as
of the date hereof and to any and all indebtedness incurred hereafter. The term “indebtedness”
as used in this Section 2, refers to all unsecured debts and obligations of the Company, including trade payables.  


 


3.           Conversion.


 


(a)           Generally.  The
holder of this Note shall have the right, exercisable at any time after thirty (30) days following the issuance of this Note but
prior to the Maturity Date, at the election of the holder of this Note, to convert all, but not less than all, of the principal
amount then outstanding into shares of the Company’s common stock, par value $0.001 per share (the “Common
Stock) at a conversion price (the “Conversion Price”) equal to $1.00 per share (the Common Stock underlying
the Note being referred to herein as the “Shares”), provided that the Company has effectuated a reverse split
at a ratio of one (1) for twenty (20) of all of the issued and outstanding Common Stock as of the date of this Note (the “Reverse
Split”).


 


(b)           Mechanics
of Conversion.  The conversion of this Note shall be conducted in the following manner: upon any conversion of all
but not less than all of the outstanding principal amount of this Note, plus all accrued but unpaid interest thereon: (i)
the Holder shall deliver a completed and executed Notice of Conversion attached hereto as Exhibit A and surrender
and deliver this Note, duly endorsed, to the Company’s office or such other address which the Company shall designate against
delivery of the certificates presenting the Shares to be delivered; (ii) in exchange for the surrendered Note, the Company shall prepare
and deliver irrevocable instructions addressed to the Company’s transfer and exchange agent, as applicable, to issue
such required number of Shares as set forth in the Conversion Notice which Shares shall be delivered to the Holder within
five (5) Business Days of the delivery of the documentation to the Company; and (iii) upon delivery of the Shares, this Note
shall become fully paid and satisfied.   


 






     

    


    

 


(c)           Adjustments
to Conversion Price.


 


(i)            Adjustments
for Stock Splits and Combinations and Stock Dividends.  If the Company shall at any time or from time to time
after the date hereof, effect a stock split (other than the Reverse Split contemplated by this Note) or combination of the outstanding
Common Stock or pay a stock dividend in shares of Common Stock, then the Conversion Price shall be proportionately adjusted. Any
adjustments under this Section 3(c)(i) shall be effective at the close of business on the date the stock split or combination becomes
effective or the date of payment of the stock dividend, as applicable.


 


(ii)           Merger
Sale, Reclassification, etc. In case of any (A) consolidation or merger (including a merger in which the Company
is the surviving entity), (B) sale or other disposition of all or substantially all of the Company’s assets or distribution
of property to shareholders (other than distributions payable out of earnings or retained earnings), or reclassification, change
or conversion of the outstanding securities of the Company or of any reorganization of the Company (or any other corporation the
stock or securities of which are at the time receivable upon the conversion of this Note) or any similar corporate reorganization
on or after the date hereof, then and in each such case the Holder of this Note, upon the conversion hereof at any time thereafter
shall be entitled to receive, in lieu of the stock or other securities and property receivable upon the conversion hereof prior
to such consolidation, merger, sale or other disposition, reclassification, change, conversion or reorganization, the stock or
other securities or property to which such Holder would have been entitled upon such consummation if such Holder had converted
this Note immediately prior thereto.


 


(iii)          Adjustments
for Issuance of Additional Shares of Common Stock.


 


(A)          In
the event the Company, shall, at any time, from time to time, issue or sell any additional shares of Common Stock (other than pursuant
to Common Stock Equivalents (hereafter defined) granted or issued prior to the issuance date of this Note) (“Additional
Shares of Common Stock”), at a price per share less than the Conversion Price then in effect or without consideration,
then the Conversion Price upon each such issuance shall be adjusted to that price (rounded to the nearest cent) determined by multiplying
the Conversion Price then in effect by a fraction: 


 


(1)           the
numerator of which shall be equal to the sum of (x) the number of shares of Common Stock outstanding immediately prior to the issuance
of such Additional Shares of Common Stock plus (y) the number of shares of Common Stock (rounded to the nearest
whole share) which the aggregate consideration for the total number of such Additional Shares of Common Stock so issued would purchase
at a price per share equal to the Conversion Price then in effect, and


 


(2)           the
denominator of which shall be equal to the number of shares of Common Stock outstanding immediately after the issuance of such
Additional Shares of Common Stock.


 


(B)          The
provisions of paragraph (A) of Section 3(iii) shall not apply to any issuance of Additional Shares of Common Stock for which an
adjustment is provided elsewhere in this Section 3).  No adjustment of the number of Shares for which this Note shall
be convertible shall be made under this clause (iii) upon the issuance of any Additional Shares of Common Stock which are issued
pursuant to the exercise of any Common Stock Equivalents, if any such adjustment shall previously have been made upon the issuance
of such Common Stock Equivalents pursuant to the other provisions of this Section 3.


 


(C)           Issuance
of Common Stock Equivalents.  The provisions of this Section 3(iii) shall apply if (a) the Company, at any time after
the issuance date of this Note, shall issue any securities convertible into or exchangeable for, directly or indirectly, Common
Stock (“Convertible Securities”), other than the Note, or (b) any rights or warrants or options to purchase
any such Common Stock or Convertible Securities (collectively, the “Common Stock Equivalents”) shall be issued
or sold.  If the price per share for which Additional Shares of Common Stock may be issuable pursuant to any such Common
Stock Equivalent shall be less than the applicable Conversion Price then in effect, or if, after any such issuance of Common Stock
Equivalents, the price per share for which Additional Shares of Common Stock may be issuable thereafter is amended or adjusted,
and such price as so amended shall be less than the applicable Conversion Price in effect at the time of such amendment or adjustment,
then the applicable Conversion Price upon each such issuance or amendment shall be adjusted as provided in the first sentence of
subsection (iii)(A) of this Section 3.  No adjustment shall be made to the Conversion Price upon the issuance of Common
Stock pursuant to the exercise, conversion or exchange of any Convertible Security or Common Stock Equivalent where an adjustment
to the Conversion Price was made as a result of the issuance or purchase of any Convertible Security or Common Stock Equivalent.

(D)          Certain
Issues Excepted.  Anything herein to the contrary notwithstanding, the Company shall not be required to make any
adjustment to the Conversion Price under this Section 3 in connection with securities of the Company issued: (i) in connection
with a merger, acquisition or consolidation, (ii) in connection with bona fide joint venture, strategic license or similar business
partnering arrangements (provided that the transaction or arrangement is not primarily for the purpose of raising capital from
Person whose primary business is investing in securities), and (iii) in connection with any share split, share dividend, recapitalization
or similar transaction by the Company for which adjustment is made pursuant to this Section 3.


 


(e)           Elimination
of Fractional Interests.  No fractional shares of Common Stock shall be issued upon conversion of this Note, nor
shall the Company be required to pay cash in lieu of fractional interests, it being the intent of the parties that all fractional
interests shall be eliminated and that all issuances of Common Stock shall be rounded up to the nearest whole share.

to or acquiesced in by the Company or shall result in the entry of an order for relief;
