THE SECURITIES REPRESENTED BY THIS CERTIFICATE MAY NOT BE OFFERED
FOR SALE, SOLD OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT FILED UNDER THE SECURITIES ACT OF
1933, AS AMENDED, OR PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT.


 


This certifies that, for good and valuable
consideration, receipt of which is hereby acknowledged, Joseph Stone Capital, LLC (“Holder”) is entitled to
purchase, subject to the terms and conditions of this Warrant, from BAIKANG BIOLOGICAL GROUP HOLDINGS LIMITED, a British Virgin
Islands company (the “Company”), up to [        ] fully paid
and nonassessable shares of the Company’s common share, $0.001 par value per share (“Common Shares”)
of the Company, in accordance with Section 2 hereof during the period commencing on [        ]
[180 days from the commencement of the public offering] (the “Commencement Date”) and ending at
5:00 p.m. New York time, [        ] [three (3) years from the commencement date
of the public offering] (the “Expiration Date”), at which time this Warrant will expire and become void
unless earlier terminated as provided herein. The Common Shares of the Company for which this Warrant is exercisable, as adjusted
from time to time pursuant to the terms hereof, are hereinafter referred to as the “Shares.”


 


1.            Exercise
Price. The initial purchase price for the Shares shall be $[        ] per
share. Such price shall be subject to adjustment pursuant to the terms hereof (such price, as adjusted from time to time, is hereinafter
referred to as the “Exercise Price”).


 


2.            Exercise
and Payment.


 


(a)          Cash
Exercise. At any time after the Commencement Date, this Warrant may be exercised, in whole or in part, from time to time
by the Holder, during the term hereof, by surrender of this Warrant and the Notice of Exercise annexed hereto duly completed and
executed by the Holder to the Company at the principal executive offices of the Company, together with payment in the amount obtained
by multiplying the Exercise Price then in effect by the number of Shares thereby purchased, as designated in the Notice of Exercise.
Payment may be in cash or by check payable to the order of the Company.


 


(b)          Net
Issuance. In lieu of payment of the Exercise Price described in Section 2(a), the Holder may elect to receive, without
the payment by the Holder of any additional consideration, shares equal to the value of this Warrant or any portion hereof by the
surrender of this Warrant or such portion to the Company, with the Notice of Exercise duly executed and electing the cashless exercise
option, at the principal executive offices of the Company. Thereupon, the Company shall issue to the Holder such number of fully
paid and nonassessable Shares as is computed using the following formula:


 


		where:	X = Y (A-B)



 


X =        the number
of Shares to be issued to the Holder pursuant to this Section 2.


Y =        the number
of Shares covered by this Warrant in respect of which the net issuance election is made pursuant to this Section 2.


A =        the fair market
value of one share of Common Share, as determined in accordance with the provisions of this Section 2.


B =        the Exercise
Price in effect under this Warrant at the time the net issuance election is made pursuant to this Section 2.


 






    	 	 	 



     


    

 


For purposes of this Section 2, the “fair market value”
per share of the Common Share shall mean:


 


(i)           If
the Common Share is traded on a national securities exchange or admitted to unlisted trading privileges on such an exchange, or
is listed on the Nasdaq Global Select Market, Nasdaq Global Market or Nasdaq Capital Market, or an over-the-counter quotation system,
the fair market value shall be the last reported sale price of the Common Share on such exchange, the Nasdaq Global Select Market,
Nasdaq Global Market, the Nasdaq Capital Market or over-the-counter quotation system on the last business day before the effective
date of exercise of the Net Issuance Election or if no such sale is made on such day, the mean of the closing bid and asked prices
such day on such exchange, the Nasdaq Global Select Market, the Nasdaq Global Market, the Nasdaq Capital Market or over-the-counter
quotation system; and


 


(ii)          If
the Common Share is not so listed or admitted to unlisted trading privileges and bid and ask prices are not reported, the fair
market value shall be the price per share which the Company could obtain from a willing buyer for shares sold by the Company for
authorized but unissued shares, as such price shall be determined by mutual agreement of the Company and the Holder of this Warrant.


 


3.            Reservation
of Shares. The Company hereby agrees that at all times during the term of this Warrant there shall be reserved for issuance
and delivery upon exercise of this Warrant such number of Common Shares or other shares of capital stock of the Company from time
to time issuable upon exercise of this Warrant. All such shares shall be duly authorized, and when issued upon such exercise, shall
be validly issued, fully paid and non-assessable, free and clear of all liens, security interests, charges and other encumbrances
or restrictions on sale and free and clear of all preemptive rights.


 


4.            Delivery
of Shares.


 


(a)          Shares
purchased hereunder shall be transmitted by the Company’s transfer agent to the Holder by crediting the account of the Holder’s
prime broker with The Depository Trust Company through its Deposit or Withdrawal at Custodian system (“DWAC”)
if the Company is then a participant in such system and either (A) there is an effective registration statement permitting the
issuance of the Shares to or resale of the Shares by the Holder or (B) the shares are eligible for resale by the Holder without
volume or manner-of-sale limitations or the need for current public information pursuant to Rule 144, and otherwise by physical
delivery to the address specified by the Holder in the Notice of Exercise by the date that is five (5) Trading Day after the delivery
to the Company of the Notice of Exercise (provided, in the case of an exercise for cash pursuant to Section 2(a) hereof, the Company
has received the cash exercise price) (such date, the “Share Delivery Date”). The Shares shall be deemed to
have been issued, and Holder or any other person so designated to be named therein shall be deemed to have become a holder of record
of such shares for all purposes, as of the date the Warrant has been exercised, with payment to the Company of the Exercise Price
(or by cashless exercise, if permitted).


 


(b)          If
this Warrant shall have been exercised in part, the Company shall, at the request of a Holder and upon surrender of this Warrant
certificate, at the time of delivery of the Shares, deliver to the Holder a new Warrant evidencing the rights of the Holder to
purchase the unpurchased Shares called for by this Warrant, which new Warrant shall in all other respects be identical with this
Warrant.


 


5.            No
Fractional Shares. No fractional shares or scrip representing fractional shares will be issued upon exercise of this Warrant.
If upon any exercise of this Warrant a fraction of a share results, the Company will pay the Holder the difference between the
cash value of the fractional share and the portion of the Exercise Price allocable to the fractional share.


 


6.            Listing.
Prior to the issuance of any Common Shares upon exercise of this Warrant, the Company shall secure the listing of such Common Shares
upon each national securities exchange or automated quotation system, if any, upon which Common Shares are then listed (subject
to official notice of issuance upon exercise of this Warrant) and shall maintain, so long as any other Common Shares shall be so
listed, such listing of all Common Shares from time to time issuable upon the exercise of this Warrant; and the Company shall so
list on each national securities exchange or automated quotation system, and shall maintain such listing of, any other shares of
capital stock of the Company issuable upon the exercise of this Warrant if and so long as any shares of the same class shall be
listed on such national securities exchange or automated quotation system.


 


7.            Charges,
Taxes and Expenses. The Company shall pay all transfer taxes or other incidental charges, if any, in connection with the
transfer of the Shares purchased pursuant to the exercise hereof from the Company to the Holder.


 






    	 	 	 



     


    

 


8.            Loss,
Theft, Destruction or Mutilation of Warrant. Upon receipt by the Company of evidence reasonably satisfactory to it of the
loss, theft, destruction or mutilation of this Warrant, and in case of loss, theft or destruction, of indemnity or security reasonably
satisfactory to the Company, and upon reimbursement to the Company of all reasonable expenses incidental thereto, and upon surrender
and cancellation of this Warrant, if mutilated, the Company will make and deliver a new Warrant of like tenor and dated as of such
cancellation, in lieu of this Warrant.


 


9.            Saturdays,
Sundays, Holidays, Etc. If the last or appointed day for the taking of any action or the expiration of any right required
or granted herein shall be a Saturday or a Sunday or shall be a legal holiday, then such action may be taken or such right may
be exercised on the next succeeding weekday that is not a legal holiday.


 


10.          Adjustment
of Exercise Price and Number of Shares. The Exercise Price and the number of and kind of securities purchasable upon exercise
of this Warrant shall be subject to adjustment from time to time as follows:


 


(a)          Subdivisions,
Combinations and Other Issuances. If the Company shall at any time after the date hereof but prior to the expiration of
this Warrant subdivide its outstanding securities as to which purchase rights under this Warrant exist, by split-up or otherwise,
or combine its outstanding securities as to which purchase rights under this Warrant exist, the number of Shares as to which this
Warrant is exercisable as of the date of such subdivision, split-up or combination will be proportionately increased in the case
of a subdivision, or proportionately decreased in the case of a combination. Appropriate adjustments also will be made to the Exercise
Price, but the aggregate purchase price payable for the total number of Shares purchasable under this Warrant as of such date shall
remain the same.


 


(b)          Stock
Dividend. If at any time after the date hereof the Company declares a dividend or other distribution on Common Share payable
in Common Share or Convertible Securities without payment of any consideration by such holder for the additional Common Shares
or the Convertible Securities (including the additional Common Shares issuable pursuant to the terms thereof), then the number
of Common Shares for which this Warrant may be exercised shall be increased as of the record date (or the date of such dividend
distribution if no record date is set) for determining which holders of Common Share shall be entitled to receive such dividend,
in proportion to the increase in the number of outstanding shares (and Common Shares issuable pursuant to the terms of the Convertible
Securities) of Common Share as a result of such dividend, and the Exercise Price shall be adjusted so that the aggregate amount
payable for the purchase of all the Shares issuable hereunder immediately after the record date (or on the date of such distribution,
if applicable) for such dividend will equal the aggregate amount so payable immediately before such record date (or on the date
of such distribution, if applicable). As used herein, “Convertible Securities” means evidences of indebtedness,
shares of stock or other securities that are convertible into or exchangeable for, with or without payment of additional consideration,
Common Shares, either immediately or upon the arrival of a specified date or the happening of a specified event or both.


 


(c)          Other
Distributions. If at any time after the date hereof the Company distributes to holders of its Common Share, other than
as part of its dissolution or liquidation or the winding up of its affairs, any shares of its capital stock, any evidence of indebtedness
or any of its assets (other than cash, Common Share or Convertible Securities), then the Company may, at its option, either (i) decrease
the Exercise Price of this Warrant by an appropriate amount based upon the value distributed on each share of Common Share as determined
in good faith by the Company's board of directors or (ii) provide by resolution of the Company's board of directors that on
exercise of this Warrant, the Holder hereof shall thereafter be entitled to receive, in addition to the Common Shares otherwise
receivable on exercise hereof, the number of shares or other securities or property which would have been received had this Warrant
at the time been exercised.


 


(d)          Merger.
If at any time after the date hereof there shall be a merger or consolidation of the Company with or into another corporation when
the Company is not the surviving corporation, then the Holder shall thereafter be entitled to receive upon exercise of this Warrant,
during the period specified herein and upon payment of the aggregate Exercise Price then in effect, the number of shares or other
securities or property of the successor corporation resulting from such merger or consolidation, which would have been received
by Holder for the Shares subject to this Warrant had this Warrant been exercised at such time.


 






    	 	 	 



     


    

 


(e)          Reclassification,
Etc. If at any time after the date hereof there shall be a change or reclassification of the securities as to which purchase
rights under this Warrant exist into the same or a different number of securities of any other class or classes, then the Holder
shall thereafter be entitled to receive upon exercise of this Warrant, during the period specified herein and upon payment of the
Exercise Price then in effect, the number of shares or other securities or property resulting from such change or reclassification,
which would have been received by Holder for the Shares subject to this Warrant had this Warrant been exercised at such time.


 


11.          Notice
of Adjustments; Notices. Whenever the Exercise Price or number of Shares purchasable hereunder is adjusted pursuant to
Section 10 hereof, the Company must execute and deliver to the Holder a certificate setting forth, in reasonable detail, the event
requiring the adjustment, the amount of the adjustment, the method by which such adjustment was calculated and the Exercise Price
and number of and kind of securities purchasable hereunder after giving effect to such adjustment, and must cause a copy of such
certificate to be mailed (by first class mail, postage prepaid) to the Holder.


 


12.          Rights
As Stockholder; Notice to Holders. Nothing contained in this Warrant will be construed as conferring upon the Holder or
his or its permitted transferees the right to vote or to receive dividends or to consent or to receive notice as a shareholder
in respect of any meeting of shareholders for the election of directors of the Company or of any other matter, or any rights whatsoever
as shareholders of the Company. The Company will notify the Warrant Holder by registered mail if at any time prior to the expiration
or exercise in full of the Warrant, any of the following events occur:


 


(a)          a
dissolution, liquidation or winding up of the Company shall be proposed;


 


(b)          a
capital reorganization or reclassification of the Common Share (other than a subdivision or combination of the outstanding Common
Share and other than a change in the par value of the Common Share) or any consolidation or merger of the Company with or into
another corporation (other than a consolidation or merger in which the Company is the continuing corporation and that does not
result in any reclassification or change of Common Share outstanding) or in the case of any sale or conveyance to another corporation
of the property of the Company as an entirety or substantially as an entirety; or


 


(c)          a
taking by the Company of a record of the holders of any class of securities for the purpose of determining the holders thereof
who are entitled to receive any dividend (other than a cash dividend) or other distribution, any right to subscribe for, purchase
or otherwise acquire any shares of stock of any class or any other securities or property, or to receive any other rights.


 


Such giving of notice will be simultaneous with
the giving of notice to holders of Common Share. Such notice must specify the record date or the date of closing the stock transfer
books, as the case may be. Failure to provide such notice will not affect the validity of any action taken in connection with such
dividend, distribution or subscription rights, or proposed merger, consolidation, sale, conveyance, dissolution, liquidation or
winding up.


 


13.          Restricted
Securities. The Holder understands that if a Registration Statement is not in effect to register this Warrant or the Common
Share issuable upon exercise of this Warrant, this Warrant and, subject to the last sentence of this Section 13, the Shares purchasable
hereunder will constitute “restricted securities” under the federal securities laws inasmuch as they are, or will be,
acquired from the Company in transactions not involving a public offering and accordingly may not, under such laws and applicable
regulations, be resold or transferred without registration under the Securities Act of 1933, as amended (the “1933 Act”)
or an applicable exemption from such registration. If a Registration Statement is not in effect, unless the Shares are subsequently
registered pursuant to Section 16 of this Warrant, the Holder further acknowledges that the securities legend on Exhibit A to the
Notice of Exercise attached hereto shall be placed on any Shares issued to the Holder upon exercise of this Warrant. Notwithstanding
the foregoing, if a Holder exercises a net issuance under Section 2(b), the Shares will be deemed to be purchased under Section
3(a)(9) of the 1933 Act and will not be “restricted securities” or subject to legend if the Warrant has been held for
a period of one year or more.


 


14.          Certification
of Investment Purpose. Unless a current registration statement under the 1933 Act shall be in effect with respect to the
securities to be issued upon exercise of this Warrant, the Holder covenants and agrees that, at the time of exercise hereof, it
will deliver to the Company a written certification executed by the Holder that the securities acquired by him upon exercise hereof
are for the account of such Holder and acquired for investment purposes only and that such securities are not acquired with a view
to, or for sale in connection with, any distribution thereof.


 






    	 	 	 



     


    

 


15.          Disposition
of Shares; Transferability.


 


(a)          Holder
hereby agrees not to make any disposition of any Warrants purchased hereunder unless and until:


 


(i)           Holder
shall have notified the Company of the proposed disposition and provided a written summary of the terms and conditions of the proposed
disposition; and


 


(ii)          Holder
shall have complied with all requirements of this Warrant applicable to the disposition of the Warrant.


 


The Company shall not be required (i) to
transfer on its books any Warrants which have been sold or transferred in violation of the provisions of this Section 15 or (ii) to
treat as the owner of the Warrants, or otherwise to accord voting or dividend rights to, any transferee to whom the Shares have
been transferred in contravention of the terms of this Warrant.


 


(b)          Transfer.
This Warrant shall be transferable only on the books of the Company maintained at its principal office in c/o Baikang Biological
Group Holdings Limited, Ginkgo Biomedical Science & Technology Industrial Park, Pizhou, Jiangsu Province, People’s Republic
of China 221300 or wherever its principal office may then be located, upon delivery thereof duly endorsed by the Holder or by its
duly authorized attorney or representative, accompanied by proper evidence of succession, assignment or authority to transfer.
Upon any registration of transfer, the Company shall execute and deliver new Warrants to the person entitled thereto.


 


(c)          Limitations
on Transfer. The registered Holder of this Warrant and the Common Share issuable upon exercise hereof agrees by his, her
or its acceptance hereof, that such Holder will not: (a) sell, transfer, assign, pledge or hypothecate this Warrant for a period
of one hundred eighty (180) days following the Effective Date to anyone other than: (i) to a placement agent or, if applicable,
a selected dealer participating in the Offering, or (ii) a bona fide officer or partner of Joseph Stone Capital, LLC or of any
such placement agent or selected dealer, in each case in accordance with Financial Industry Regulatory Authority (“FINRA”)
Conduct Rule 5110(g)(1), or (b) cause this Warrant or the securities issuable hereunder to be the subject of any hedging, short
sale, derivative, put or call transaction that would result in the effective economic disposition of this Warrant or the securities
hereunder (any such action, a “Transfer”), except as provided for in FINRA Conduct Rule 5110(g)(2). On and after
180 days after the Commencement Date, transfers to others may be made subject to compliance with or exemptions from applicable
securities laws. In order to make any permitted assignment, the Holder must deliver to the Company an assignment form duly executed
and completed, together with the Warrant and payment of all transfer taxes, if any, payable in connection therewith. The Company
shall within five (5) Business Days transfer this Warrant on the books of the Company and shall execute and deliver a new Warrant
to the appropriate assignee(s) expressly evidencing the right to purchase the aggregate number of Common Shares purchasable hereunder
or such portion of such number as shall be contemplated by any such assignment. This Warrant may be divided or combined, upon request
to the Company by the Holder, into a certificate or certificates representing the right to purchase the same aggregate number of
Shares. If at the time of a Transfer, a Registration Statement is not in effect to register this Warrant, the Company may require
the Holder to make such representations, and may place such legends on certificates representing this Warrant, as may be reasonably
required in the opinion of counsel to the Company to permit a Transfer without such registration.


 






    	 	 	 



     


    

 


16.          Registration
Rights.


 


(a)          Piggyback
Registration. If at any time prior to the Expiration Date a Registration Statement is not in effect to register this Warrant
and the Common Shares issuable upon exercise of this Warrant, the Company determines to register for its own account or the account
of others under the 1933 Act any of its equity securities, other than on Form S-4 or Form S-8 or their then equivalents relating
to equity securities to be issued solely in connection with any acquisition of any entity or business, or equity securities issuable
in connection with stock option or other employee benefit plans, the Company shall send to each Holder of Warrants or Shares written
notice of such determination and, if within twenty (20) days after receipt of such notice, such Holder shall so request in writing
(hereafter a “Selling Holder”), the Company shall use commercially reasonable efforts to include in such Registration
Statement all or any part of the Shares issuable or issued upon exercise of the Warrants (the “Registrable Securities”)
such Selling Holder requests to be registered. The obligations of the Company under this Section 16(a) may be waived by Holders
holding a majority in interest of the Registrable Securities. If in connection with any primary underwritten public offering for
the account of the Company, the managing underwriter thereof shall, in its reasonable discretion, impose a limitation on the number
of Common Shares underlying the Warrants which may be included in the registration statement because, in such underwriter’s
judgment, marketing or other factors dictate such limitation is necessary to facilitate public distribution, then the Company shall
be obligated to include in such registration statement only such limited portion of the Registrable Securities with respect to
which the Selling Holder requested inclusion hereunder as the underwriter shall reasonably permit. Any exclusion of Registrable
Securities shall be made pro rata among the Holders seeking to include Registrable Securities in proportion to the number of Registrable
Securities sought to be included by such Holders; provided, however, that the Company shall not exclude any Registrable Securities
unless the Company has first excluded all outstanding securities, the holders of which are not entitled to inclusion of such securities
in such registration statement or are not entitled to pro rata inclusion with the Registrable Securities.


 


Notwithstanding the provisions of this Section 16, the Company shall
have the right at any time after it shall have given written notice pursuant to this Section 16 (irrespective of whether any written
request for inclusion of Registrable Securities shall have already been made) to elect not to file any such proposed Registration
Statement, or to withdraw the same after the filing but prior to the effective date thereof, without incurring any liability to
any Holder of Registrable Securities


 


(b)          Obligations
of the Holders. In connection with the registration of the Registrable Securities pursuant to Section 16(a), the Selling
Holders shall have the following obligations:


 


(i)           It
shall be a condition precedent to the obligations of the Company to take any action pursuant to this Agreement with respect to
each Selling Holder that such Selling Holder shall furnish to the Company such information regarding itself, the Registrable Securities
held by it and the intended method of disposition of the Registrable Securities held by it as shall be reasonably required to effect
the registration of the Registrable Securities and shall execute such documents in connection with such registration as the Company
may reasonably request. At least fifteen (15) days prior to the first anticipated filing date of the Registration Statement, the
Company shall notify each Selling Holder of the information the Company requires from each such Selling Holder (the “Requested
Information”) if such Selling Holder elects to have any of such Selling Holder's Registrable Securities included in the
Registration Statement in the case of a Registration Statement being prepared pursuant to Section 16(a).


 


(ii)          Each
Selling Holder by such Selling Holder's acceptance of the Registrable Securities agrees to cooperate with the Company as reasonably
requested by the Company in connection with the preparation and filing of the Registration Statement hereunder, unless such Selling
Holder has notified the Company in writing of such Selling Holder's election to exclude all of such Selling Holder's Registrable
Securities from the Registration Statement; and


 


(iii)         No
Selling Holder may participate in any underwritten registration hereunder unless such Selling Holder (i) agrees to sell such
Selling Holder's Registrable Securities on the basis provided in any underwriting arrangements approved by the Selling Holders
entitled hereunder to approve such arrangements, (ii) completes and executes all questionnaires, powers of attorney, indemnities,
underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements, and (iii) agrees
to pay its pro rata share of all underwriting discounts and commissions and other fees and expenses of investment bankers and any
manager or managers of such underwriting, except as provided in Section 16(d) below.


 


(c)          Obligations
of the Company. If and whenever the Company is required to use its best efforts to take action pursuant to any Federal
or state law or regulation to permit the sale or other disposition of any Shares purchasable upon exercise of this Warrant that
are then held or that may be acquired upon exercise of the Warrants in order to effect or cause the registration of any Registrable
Securities under the 1933 Act as provided in this Section 16, the Company shall, as expeditiously as practicable:


 






    	 	 	 



     


    

 


(i)           Prepare
and file with the SEC a Registration Statement or Registration Statements relating to the registration on any appropriate form
under the 1933 Act, which form shall be available for the sale of the Registrable Securities in accordance with the intended method
or methods of distribution thereof, and use its best efforts to cause such Registration Statements to become effective; provided
that before filing a Registration Statement or Prospectus or any amendment or supplements thereto, including documents incorporated
by reference after the initial filing of any Registration Statement, the Company will furnish to the Holders of the Registrable
Securities covered by such Registration Statement and the underwriters, if any, copies of all such documents provided to be filed,
which documents will be subject to the review of such Holders and underwriters;


 


(ii)          prepare
and file with the SEC such amendments and post-effective amendments to a Registration Statement as may be necessary to keep such
Registration Statement effective for a reasonable period or as otherwise provided herein; cause the related Prospectus to be supplemented
by any required Prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 under the 1933 Act; and comply with
the provisions of the 1933 Act with respect to the disposition of all securities covered by such Registration Statement during
such period in accordance with the intended methods of disposition by the sellers thereof set forth in such Registration Statement
or supplement to such Prospectus;


 


(iii)         notify
the selling Holders of Registrable Securities and the managing underwriters, if any, promptly, and (if requested by any such Person)
confirm such advice in writing, (A) when a Prospectus or any Prospectus supplement or post-effective amendment has been filed,
and, with respect to a Registration Statement or any post-effective amendment, when the same has become effective; (B) of
any request by the SEC for amendments or supplements to a Registration Statement or related Prospectus or for additional information;
(C) of the issuance by the SEC of any stop order suspending the effectiveness of a Registration Statement or the initiation
of any proceedings for that purpose; (D) if at any time the representations and warranties of the Company contemplated by
paragraph (xiv) below ceases to be true and correct in all material respects; (E) of the receipt by the Company of any
notification with respect to the suspension of the qualification of any of the Registrable Securities for sale in any jurisdiction
or the initiation or threatening of any proceeding for such purpose; and (F) of the happening of any event that makes any
statement of a material fact made in the Registration Statement, the Prospectus or any document incorporated therein by reference
untrue or which requires the making of any changes in the Registration Statement or Prospectus so that they will not contain any
untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements
therein not misleading;


 


(iv)         make
every reasonable effort to obtain the withdrawal of any order suspending the effectiveness of a Registration Statement at the earliest
possible moment;


 


(v)          if
reasonably requested by the managing underwriters, immediately incorporate in a Prospectus supplement or post-effective amendment
such information as the managing underwriters believe (on advice of counsel) should be included therein as required by applicable
law relating to such sale of Registrable Securities, including, without limitation, information with respect to the purchase price
being paid for the Registrable Securities by such underwriters and with respect to any other terms of the underwritten (or “best-efforts”
underwritten) offering; and make all required filings of such Prospectus supplement or post-effective amendment as soon as notified
of the matters to be incorporated in such Prospectus supplement or post-effective amendment;


 


(vi)         deliver
to each selling Holder of Registrable Securities and the underwriters, if any, without charge, as many copies of the Prospectus
or Prospectuses (including each preliminary Prospectus) any amendment or supplement thereto as such Persons may reasonably request;
the Company consents to the use of such Prospectus or any amendment or supplement thereto by each of the selling Holders of Registrable
Securities and the underwriters, if any, in connection with the offering and sale of the Registrable Securities covered by such
Prospectus or any Amendment or supplement thereto;


 


(vii)        prior
to any public offering of Registrable Securities, cooperate with the selling Holders of Registrable Securities, the underwriters,
if any, and their respective counsel in connection with the registration or qualification of such Registrable Securities for offer
and sale under the securities or Blue Sky laws of such jurisdictions within the United States as any selling Holder (at such Holder’s
expense) or underwriter (at Company’s expense) reasonably requests in writing, keep each such registration or qualification
effective during the period such Registration Statement is required to be kept effective and do any and all other acts or things
necessary or advisable to enable the disposition in such jurisdictions of the Registrable Securities covered by the applicable
Registration Statement; provided that the Company will not be required to qualify to do business in any jurisdiction where it is
not then so qualified or to take any action which would subject the Company to general service of process in any jurisdiction where
it is not at the time so subject;


 






    	 	 	 



     


    

 


(viii)       cooperate
with the selling Holders of Registrable Securities and the managing underwriters, if any, to facilitate the timely preparation
and delivery of certificates representing Registrable Securities to be sold and not bearing any restrictive legends; and enable
such Registrable Securities to be in such denominations and registered in such names as the managing underwriters may request at
least two Business Days prior to any sale of Registrable Securities to the underwriters;


 


(ix)         use
its best efforts to cause the Registrable Securities covered by the applicable Registration Statement to be registered with or
approved by such other governmental agencies or authorities within the United States as may be necessary to enable the seller or
sellers thereof or the underwriters, if any, to consummate the disposition of such Registrable Securities;


 


(x)          upon
the occurrence of any event contemplated by Section 16(d)(iii)(F) above, prepare a supplement or post-effective amendment
to the applicable Registration Statement or related Prospectus or any document incorporated therein by reference or file any other
required document so that, as thereafter delivered to the purchasers of the Registrable Securities being sold thereunder, such
Prospectus will not contain an untrue statement of a material fact or omit to state any material fact necessary to make the statements
therein not misleading;


 


(xi)         with
respect to each issue or class of Registrable Securities, use its best efforts to cause all Registrable Securities covered by the
Registration Statements to be listed on each securities exchange, if any, on which similar securities issued by the Company are
then listed if requested by the Holders of a majority of such issue or class of Registrable Securities;


 


(xii)        enter
into such agreements (including an underwriting agreement) and take all such other action reasonably required in connection therewith
in order to expedite or facilitate the disposition of such Registrable Securities and in such connection, if the registration is
in connection with an underwritten offering (A) make such representations and warranties to the underwriters, in such form,
substance and scope as are customarily made by issuers to underwriters in underwritten offering and confirm the same if and when
requested; (B) obtain opinions of counsel to the Company and updates thereof (which counsel and opinions in form, scope and
substance shall be reasonably satisfactory to the underwriters and selling Holders of Registrable Securities) addressed to the
underwriters and selling Holders of Registrable Securities covering the matters customarily covered in opinions requested in underwritten
offerings and such other matters as may be reasonably requested by such underwriters and selling Holders of Registrable Securities;
(C) obtain “comfort letters” and updates thereof from the Company's accountants addressed to the underwriters
and selling Holders of Registrable Securities, such letters to be in customary form and covering matters of the type customarily
covered in “comfort letters” in connection with underwritten offerings; (D) set forth in full in any underwriting
agreement entered into the indemnification provisions and procedures of Section 16(f) hereof with respect to all parties to
be indemnified pursuant to said Section; and (E) deliver such documents and certificates as may be reasonably requested by
the underwriters to evidence compliance with clause (i) above and with any customary conditions contained in the underwriting agreement
or other agreement entered into by the Company; the above shall be done at each closing under such underwriting or similar agreement
or as and to the extent required hereunder;


 


(xiii)       make
available for inspection by one or more representatives of the Holders of Registrable Securities being sold, any underwriter participating
in any disposition pursuant to such registration, and any attorney or accountant retained by such Holders or underwriter, all financial
and other records, pertinent corporate documents and properties of the Company, and cause the Company's officers, directors and
employees to supply all information reasonably requested by any such representatives, in connection with such; and


 


(xiv)       otherwise
use its best efforts to comply with all applicable Federal and state regulations; and take such other action as may be reasonably
necessary to or advisable to enable each such Holder and each such underwriter to consummate the sale or disposition in such jurisdiction
or jurisdiction in which any such Holder or underwriter shall have requested that the Registrable Securities be sold.


 






    	 	 	 



     


    

 


Except as otherwise provided in this Agreement, the Company shall
have sole control in connection with the preparation, filing, withdrawal, amendment or supplementing of each Registration Statement,
the selection of underwriters, and the distribution of any preliminary prospectus included in the Registration Statement, and may
include within the coverage thereof additional Common Shares or other securities for its own account or for the account of one
or more of its other security holders.


 


The Company may require each Seller of Registrable Securities as
to which any registration is being effected to furnish to the Company such information regarding the distribution of such securities
and such other information as may otherwise be required by the 1933 Act to be included in such Registration Statement.


 


(d)          Expenses
of Registration. All expenses (excluding fees and expenses of counsel for you and any other holder(s) and any underwriting
or selling commissions), other than underwriting discounts and commissions and other fees and expenses of investment bankers and
other than brokerage commissions, incurred in connection with registrations, filings or qualifications pursuant to Section 16(a),
including, without limitation, all registration, listing and qualifications fees, printers and accounting fees and the fees and
disbursements of counsel for the Company, shall be borne by the Company.


 


(e)          Indemnification.
In the event any Registrable Securities are included in a Registration Statement under this Agreement:


 


(i)           To
the extent permitted by law, the Company will indemnify and hold harmless each Selling Holder who holds such Registrable Securities,
the directors, if any, of such Selling Holder, the officers, if any, of such Selling Holder, each person, if any, who controls
any Selling Holder within the meaning of the 1933 Act, any underwriter (as defined in the 1933 Act) for the Selling Holders, the
directors, if any, of such underwriter and the officers, if any, of such underwriter, and each person, if any, who controls any
such underwriter within the meaning of the 1933 Act (each, an “Indemnified Person”), against any losses, claims,
damages, expenses or liabilities (joint or several) (collectively, “Claims”) to which any of them may become
subject under the 1933 Act or otherwise, insofar as such Claims (or actions or proceedings, whether commenced or threatened, in
respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in
the Registration Statement when it first became effective, or any related final prospectus, amendment or supplement thereto, or
the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which the statements therein were made, not misleading (a “Violation”).
The Company shall reimburse the Selling Holders and each such underwriter or controlling person, promptly as such expenses are
incurred and are due and payable, for any legal fees or other reasonable expenses incurred by them in connection with investigating
or defending any such Claim. Notwithstanding anything to the contrary contained herein, the indemnification agreement contained
in this Section 16(f)(1) shall not apply in such case to the extent any such Claim arising out of or based upon a Violation which
occurs in reliance upon and in conformity with information furnished in writing to the Company by any Indemnified Person or underwriter
for such Indemnified Person expressly for use in connection with the preparation of the Registration Statement or any such amendment
thereof or supplement thereto, and shall not apply to amounts paid in settlement of any Claim if such settlement is effected without
the prior written consent of the Company, which consent shall not be unreasonably withheld.


 


(ii)          In
connection with any Registration Statement in which a Selling Holder is participating, each such Selling Holder agrees to indemnify
and hold harmless, to the same extent and in the same manner set forth in Section 16(f)(i), the Company, each of its directors,
each of its officers who signs the Registration Statement, each person, if any, who controls the Company within the meaning of
the 1933 Act, any underwriter and any other stockholder selling securities pursuant to the Registration Statement or any of its
directors or officers or any person who controls such stockholder or underwriter within the meaning of the 1933 Act (collectively
and together with an Indemnified Person, an “Indemnified Party”), against any Claim to which any of them may
become subject, under the 1933 Act or otherwise, insofar as such Claim arises out of or is based upon any Violation, in each case
to the extent (and only to the extent) that such Violation occurs in reliance upon and in conformity with written information furnished
to the Company by such Selling Holder expressly for use in connection with such Registration Statement, and such Selling Holder
will reimburse any legal or other expenses reasonably incurred by them in connection with investigating or defending any such Claim;
provided, however, that the indemnity agreement contained in this Section 16(f)(ii) shall not apply to amounts paid in settlement
of any Claim if such settlement is effected without the prior written consent of such Selling Holder, which consent shall not be
unreasonably withheld.


 






    	 	 	 



     


    

 


(iii)         The
Company shall be entitled to receive indemnities from underwriters, selling brokers, dealer managers and similar securities industry
professionals participating in any distribution to the same extent as provided above, with respect to information furnished in
writing by such persons expressly for inclusion in the Registration Statement.


 


(iv)         Promptly
after receipt by an Indemnified Person or Indemnified Party under this Section 16(f) of notice of the commencement of any action
or proceeding (including any governmental action or investigation), such Indemnified Person or Indemnified Party shall, if a Claim
in respect thereof is made against any indemnifying party under this Section 16(f), deliver to the indemnifying party a written
notice of the commencement thereof and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying
party so desires, jointly with any other indemnifying party similarly noticed, to assume control of the defense thereof with counsel
mutually satisfactory to the indemnifying parties; provided, however, that an Indemnified Person or Indemnified Party shall have
the right to retain its own counsel, with the fees and expenses to be paid by the indemnifying party, if, in the reasonable opinion
of counsel retained by the indemnifying party, the representation by such counsel of the Indemnified Person or Indemnified Party
and the indemnifying party would be inappropriate due to actual or potential differing interests between such Indemnified Person
or Indemnified Party and any other party represented by such counsel in such proceeding. The Indemnifying Party shall pay for only
one separate legal counsel for the Indemnified Parties; such legal counsel shall be selected by the Indemnified Parties holding
a majority in interest of the Registrable Securities. The failure to deliver written notice to the indemnifying party within a
reasonable time of the commencement of any such action shall not relieve such indemnifying party of any liability to the Indemnified
Person or Indemnified Party under this Section 16(f), except to the extent that the indemnifying party is prejudiced in its
ability to defend such action. The indemnification required by this Section 16(f) shall be made by periodic payments of the amount
thereof during the course of the investigation or defense, as such expense, loss, damage or liability is incurred and is due and
payable.


 


(v)          Notwithstanding
any of the foregoing, if, in connection with an underwritten public offering of Registrable Securities, the Company, the Selling
Holders and the underwriter(s) enter into an underwriting or purchase agreement relating to such offering which contains provisions
covering indemnification and contribution among the parties, the indemnification and contribution provisions of this Section 16(f)
shall be deemed inoperative for purposes of such offering.


 


(f)          Contribution.
To the extent any indemnification by an indemnifying party is prohibited or limited by law, the indemnifying party agrees to make
the maximum contribution with respect to any amounts for which it would otherwise be liable under Section 16(f) to the fullest
extent permitted by law; provided, however, that (i) no contribution shall be made under circumstances where
the maker would not have been liable for indemnification under the fault standards set forth in Section 16(f), (ii) no
seller of Registrable Securities guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act)
shall be entitled to contribution from any seller of Registrable Securities who was not guilty of such fraudulent misrepresentation,
and (iii) contribution by any seller of Registrable Securities shall be limited in amount to the net amount of proceeds received
by such seller from the sale of such Registrable Securities.


 


(g)          Reports
Under Exchange Act. With a view to making available to the Holders the benefits of Rule 144 promulgated under the 1933
Act or any other similar rule or regulation of the SEC that may at any time permit the Holders to sell securities of the Company
to the public without registration (“Rule 144”), the Company agrees to:


 


(i)           make
and keep public information available, as those terms are understood and defined in Rule 144; and


 






    	 	 	 



     


    

 


(ii)          file
with the SEC in a timely manner all reports and other documents required of the Company under the 1933 Act and the Securities Exchange
Act of 1934, as amended (the “Exchange Act”); and


 


(iii)         furnish
to each Holder so long as such Holder owns Registrable Securities, promptly upon request, (i) a written statement by the Company
that it has complied with the reporting requirements of Rule 144, (ii) a copy of the most recent annual or quarterly report of
the Company and such other reports and documents so filed by the Company, and (iii) such other information as may be reasonably
requested to permit the Holders to sell such securities without registration pursuant to Rule 144 (excluding fees and expenses
incurred for obtaining legal opinion for such securities sales).


 


(h)          Assignment
of the Registration Rights. The rights to have the Company register Registrable Securities pursuant to this Agreement shall
be automatically assigned by the Holders to transferees or assignees of all or any portion of such securities only if: (i) the
Holder agrees in writing with the transferee or assignee to assign such rights, (ii) the Company is, within a reasonable time after
such transfer or assignment, furnished with written notice of the name and address of such transferee or assignee, (iii) such assignment
is in accordance with and permitted by law and all other agreements between the transferor or assignor and the Company, including
without limitation, stockholder's agreements, warrants and subscription agreements, and the transferor or assignor otherwise is
not in material default of any obligation to the Company under any such other agreement, and (iv) at or before the time the Company
received the written notice contemplated by clause (ii) of this sentence, the transferee or assignee agrees in writing with the
Company to be bound by all of the provisions contained herein.


 


17.          Miscellaneous.


 


(a)          Construction.
Unless the context indicates otherwise, the term “Holder” shall include any transferee or transferees of this
