Option.


 


THIS CERTIFIES THAT, in consideration of $___ duly paid by or on behalf of _________ (“Holder”),
as registered owner of this Purchase Option, to Opes Acquisition Corp. (“Company”), Holder is entitled,
at any time or from time to time upon the later of the consummation of a Business Combination or ____________, 2019 (“Commencement

Date”) of the Company’s registration statement (“Registration Statement”) pursuant
to which Units are offered for sale to the public (“Offering”), but not thereafter (“Expiration
Date”), to subscribe for, purchase and receive, in whole or in part, up to ______________ (_______) units (“Units”)
of the Company, each Unit consisting of one share of common stock of the Company, par value $0.0001 per share (“Common
Stock”), and one warrant (“Warrant(s)”), each warrant to purchase one share of Common Stock.
Each Warrant is the same as the warrant included in the Units being registered for sale to the public by way of the Registration
Statement (“Public Warrants”). If the Expiration Date is a day on which banking institutions are authorized
by law to close, then this Purchase Option may be exercised on the next succeeding day which is not such a day in accordance with
the terms herein. Notwithstanding anything to the contrary, the Holder agrees that it will not be permitted to exercise this Purchase
Option or the Warrants underlying this Purchase Option after the five year anniversary of the Effective Date. During the period
beginning on the date hereof and ending on the Expiration Date, the Company agrees not to take any action that would terminate
the Purchase Option. This Purchase Option is initially exercisable at $10.00 per Unit so purchased; provided, however, that upon
the occurrence of any of the events specified in Section 6 hereof, the rights granted by this Purchase Option, including the exercise
price per Unit and the number of Units (and shares of Common Stock and Warrants) to be received upon such exercise, shall be adjusted
as therein specified. The term “Exercise Price” shall mean the initial exercise price or the adjusted
exercise price, depending on the context.


 




     


     


    

 


2.           Exercise.


 


2.1         Exercise
Form. In order to exercise this Purchase Option, the exercise form attached hereto must be duly executed and completed
and delivered to the Company, together with this Purchase Option and payment of the Exercise Price for the Units being purchased
payable in cash or by certified check or official bank check. If the subscription rights represented hereby shall not be exercised
at or before 5:00 p.m., Eastern time, on the Expiration Date this Purchase Option shall become and be void without further force
or effect, and all rights represented hereby shall cease and expire.


 


2.2         Legend.
Each certificate for the securities purchased under this Purchase Option shall bear a legend as follows unless such securities
have been registered under the Securities Act of 1933, as amended (“Act”):


 


“The securities represented by this certificate have not
been registered under the Securities Act of 1933, as amended (“Act”) or applicable state law. The securities may not
be offered for sale, sold or otherwise transferred except pursuant to an effective registration statement under the Act, or pursuant
to an exemption from registration under the Act and applicable state law.”


 


2.3         Cashless
Exercise.


 


2.3.1           Determination
of Amount. In lieu of the payment of the Exercise Price multiplied by the number of Units for which this Purchase Option is
exercisable (and in lieu of being entitled to receive shares of Common Stock and Warrants) in the manner required by Section 2.1,
and subject to Section 6.1 hereof, the Holder shall have the right (but not the obligation) to convert on a cashless basis any
exercisable but unexercised portion of this Purchase Option into Units (“Cashless Exercise Right”) as
follows: upon exercise of the Cashless Exercise Right, the Company shall deliver to the Holder (without payment by the Holder
of any of the Exercise Price in cash) that number of Units (or that number of shares of Common Stock and Warrants comprising that
number of Units) equal to the number of Units to be exercised multiplied by the quotient obtained by dividing (x) the “Value”
(as defined below) of the portion of the Purchase Option being exercised by (y) the Current Market Value (as defined below). The
“Value” of the portion of the Purchase Option being exercised shall equal the remainder derived from subtracting (a)
(i) the Exercise Price multiplied by (ii) the number of Units underlying the portion of this Purchase Option being exercised from
(b) the Current Market Value of a Unit multiplied by the number of Units underlying the portion of the Purchase Option being exercised.
As used herein, the term “Current Market Value” per Unit at any date means: (A) in the event that the Units, Common
Stock and Public Warrants are still trading, (i) if the Units are listed on a national securities exchange or quoted on the OTC
Bulletin Board (or successor exchange), the average reported last sale price of the Units in the principal trading market for
the Units as reported by the exchange, Nasdaq or the Financial Industry Regulatory Authority (“FINRA”),
as the case may be, for the three trading days preceding the date in question; or (ii) if the Units are not listed on a national
securities exchange or quoted on the OTC Bulletin Board (or successor exchange), but is traded in the residual over-the-counter
market, the average reported last sale price for Units for the three trading days preceding the date in question for which such
quotations are reported by the Pink Sheets, LLC or similar publisher of such quotations; (B) in the event that the Units are not
still trading but the Common Stock and Public Warrants underlying the Units are still trading, the aggregate of (i) the product
of (x) the Current Market Price of the Common Stock and (y) the number of shares of Common Stock underlying one Unit plus (ii)
the product of (x) the Current Market Price of the Public Warrants and (y) the number of the Warrants included in one Unit; or
(C) in the event that neither the Units nor Public Warrants are still trading, the aggregate of (i) the product of (x) the Current
Market Price of the Common Stock and (y) the number of shares of Common Stock underlying one Unit plus (ii) the remainder derived
from subtracting (x) the exercise price of the Warrants multiplied by the number of shares of Common Stock issuable upon exercise
of the Warrants underlying one Unit from (y) the product of (aa) the Current Market Price of the Common Stock multiplied by (bb)
the number of shares of Common Stock underlying the Warrants included in each such Unit. The “Current Market Price”
shall mean (i) if the Common Stock (or Public Warrants, as the case may be) is listed on a national securities exchange or quoted
on the OTC Bulletin Board (or successor exchange), the average reported last sale price of the Common Stock (or Public Warrants)
in the principal trading market for the Common Stock (or Public Warrants) as reported by the exchange, Nasdaq or FINRA, as the
case may be, for the three trading days preceding the date in question; (ii) if the Common Stock (or Public Warrants, as the case
may be) is not listed on a national securities exchange or quoted on the OTC Bulletin Board (or successor exchange), but is traded
in the residual over-the-counter market, the average reported last sale price for the Common Stock (or Public Warrants) on for
the three trading days preceding the date in question for which such quotations are reported by the Pink Sheets, LLC or similar
publisher of such quotations; and (iii) if the fair market value of the Common Stock cannot be determined pursuant to clause (i)
or (ii) above, such price as the Board of Directors of the Company shall determine, in good faith. In the event the Public Warrants
have expired and are no longer exercisable, no “Value” shall be attributed to the Warrants underlying this Purchase
Option or Common Stock issuable upon exercise of the Warrant.

2.3.2           Mechanics
of Cashless Exercise. The Cashless Exercise Right may be exercised by the Holder on any business day on or after the Commencement
Date and not later than the Expiration Date by delivering the Purchase Option with the duly executed exercise form attached hereto
with the cashless exercise section completed to the Company, exercising the Cashless Exercise Right and specifying the total number
of Units the Holder will purchase pursuant to such Cashless Exercise Right.


 


2.4         No
Obligation to Net Cash Settle. Notwithstanding anything to the contrary contained in this Purchase Option, in no event will
the Company be required to net cash settle the exercise of the Purchase Option or the Warrants underlying the Purchase Option.
The holder of the Purchase Option and the Warrants underlying the Purchase Option will not be entitled to exercise the Purchase
Option or the Warrants underlying such Purchase Option unless it exercises such Purchase Option pursuant to the Cashless Exercise
Right or a registration statement is effective, or an exemption from the registration requirements is available at such time and,
if the holder is not able to exercise the Purchase Option or underlying Warrants, the Purchase Option and/or the underlying Warrants,
as applicable, will expire worthless.


 


3.           Transfer.


 


3.1         General
Restrictions. The registered Holder of this Purchase Option, by its acceptance hereof, agrees that it will not sell, transfer,
assign, pledge or hypothecate this Purchase Option (or the Common Stock and Warrants underlying this Purchase Option) for a period
of 180 days pursuant to FINRA Conduct Rule 5110(g)(1) following the Effective Date to anyone other than (i) EBC or an underwriter
or selected dealer in connection with the Offering, or (ii) a bona fide officer or partner of EBC or of any such underwriter
or selected dealer. Additionally, pursuant to FINRA Conduct Rule 5110(g), the Purchase Option (or the Common Stock and Warrants
underlying this Purchase Option) will not be the subject of any hedging, short sale, derivative, put or call transaction that would
result in the economic disposition of the securities by any person for a period of 180 days immediately following the Effective
Date. On and after the 181st day following the Effective 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
the assignment form attached hereto duly executed and completed, together with the Purchase Option and payment of all transfer
taxes, if any, payable in connection therewith. The Company shall within five business days transfer this Purchase Option on the
books of the Company and shall execute and deliver a new Purchase Option or Purchase Options of like tenor to the appropriate assignee(s)
expressly evidencing the right to purchase the aggregate number of Units purchasable hereunder or such portion of such number as
shall be contemplated by any such assignment.


 


3.2         Restrictions
Imposed by the Act. The securities evidenced by this Purchase Option shall not be transferred unless and until (i) the
Company has received the opinion of counsel for the Holder that the securities may be transferred pursuant to an exemption from
registration under the Act and applicable state securities laws, the availability of which is established to the reasonable satisfaction
of the Company (the Company hereby agreeing that the opinion of Graubard Miller shall be deemed satisfactory evidence of the availability
of an exemption), or (ii) a registration statement or a post-effective amendment to the Registration Statement relating to
such securities has been filed by the Company and declared effective by the Securities and Exchange Commission (the “Commission”)
and compliance with applicable state securities law has been established.

Purchase Options to be Issued.


 


4.1         Partial

whole or in part.  In the event of the exercise or assignment hereof in part only, upon surrender of this Purchase Option
for cancellation, together with the duly executed exercise or assignment form and funds sufficient to pay any Exercise Price (except
to the extent that the Holder elects to exercise this Purchase Option by means of a cashless exercise as provided in Section 2.3
above) and/or transfer tax, the Company shall cause to be delivered to the Holder without charge a new Purchase Option of like
tenor to this Purchase Option in the name of the Holder evidencing the right of the Holder to purchase the number of Units purchasable
hereunder as to which this Purchase Option has not been exercised or assigned.


 


4.2         Lost
Certificate. Upon receipt by the Company of evidence satisfactory to it of the loss, theft, destruction or mutilation of this
Purchase Option and of reasonably satisfactory indemnification or the posting of a bond, the Company shall execute and deliver
a new Purchase Option of like tenor and date. Any such new Purchase Option executed and delivered as a result of such loss, theft,
mutilation or destruction shall constitute a substitute contractual obligation on the part of the Company.


    


5.           Registration
Rights.


 


5.1         Demand
Registration.


 


5.1.1           Grant
of Right. The Company, upon written demand (“Initial Demand Notice”) of the Holder(s) of at least
51% of the Purchase Options and/or the underlying Units and/or the underlying securities (“Majority Holders”),
agrees to use its best efforts to register (the “Demand Registration”) under the Act on one occasion,
all or any portion of the Purchase Options requested by the Majority Holders in the Initial Demand Notice and all of the securities
underlying such Purchase Options, including the Units, Common Stock, the Warrants and the Common Stock underlying the Warrants
(collectively, the “Registrable Securities”). On such occasion, the Company will use its best efforts
to file a registration statement or a post-effective amendment to the Registration Statement covering the Registrable Securities
within sixty (60) days after receipt of the Initial Demand Notice and use its best efforts to have such registration statement
or post-effective amendment declared effective as soon as possible thereafter. The demand for registration may be made at any
time during a period of five years beginning on the Effective Date. The Initial Demand Notice shall specify the number of shares
of Registrable Securities proposed to be sold and the intended method(s) of distribution thereof. The Company will notify all
holders of the Purchase Options and/or Registrable Securities of the demand within ten (10) days from the date of the receipt
of any such Initial Demand Notice. Each holder of Registrable Securities who wishes to include all or a portion of such holder’s
Registrable Securities in the Demand Registration (each such holder including shares of Registrable Securities in such registration,
a “Demanding Holder”) shall so notify the Company within fifteen (15) days after the receipt by the
holder of the notice from the Company. Upon any such request, the Demanding Holders shall be entitled to have their Registrable
Securities included in the Demand Registration, subject to Section 5.1.4. The Company shall not be obligated to effect more than
one (1) Demand Registration under this Section 5.1 in respect of all Registrable Securities.


 


5.1.2           Effective
Registration. A registration will not count as a Demand Registration until the registration statement filed with the Commission
with respect to such Demand Registration has been declared effective and the Company has complied with all of its obligations under
this Agreement with respect thereto.


 


5.1.3           Underwritten
Offering. If the Majority Holders so elect and such holders so advise the Company as part of the Initial Demand Notice, the
offering of such Registrable Securities pursuant to such Demand Registration shall be in the form of an underwritten offering.
In such event, the right of any holder to include its Registrable Securities in such registration shall be conditioned upon such
holder’s participation in such underwriting and the inclusion of such holder’s Registrable Securities in the underwriting
to the extent provided herein. All Demanding Holders proposing to distribute their securities through such underwriting shall enter
into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting by the Majority
Holders.


 




    	 	 4	 



     


    

 


5.1.4           Reduction
of Offering. If the managing underwriter or underwriters for a Demand Registration that is to be an underwritten offering advises
the Company and the Demanding Holders in writing that the dollar amount or number of shares of Registrable Securities which the
Demanding Holders desire to sell, taken together with all other Common Stock or other securities which the Company desires to sell
and the Common Stock, if any, as to which registration has been requested pursuant to written contractual piggy-back registration
rights held by other stockholders of the Company who desire to sell, exceeds the maximum dollar amount or maximum number of shares
that can be sold in such offering without adversely affecting the proposed offering price, the timing, the distribution method,
or the probability of success of such offering (such maximum dollar amount or maximum number of shares, as applicable, the “Maximum
Number of Shares”), then the Company shall include in such registration: (i) first, the Registrable Securities
as to which Demand Registration has been requested by the Demanding Holders (pro rata in accordance with the number of shares that
each such Person has requested be included in such registration, regardless of the number of shares held by each such Person (such
proportion is referred to herein as “Pro Rata”)) that can be sold without exceeding the Maximum Number
of Shares; (ii) second, to the extent that the Maximum Number of Shares has not been reached under the foregoing clause (i),
the Common Stock or other securities that the Company desires to sell that can be sold without exceeding the Maximum Number of
Shares; (iii) third, to the extent that the Maximum Number of Shares has not been reached under the foregoing clauses (i)
and (ii), the Common Stock or other securities registrable pursuant to the terms of the Registration Rights Agreement between the
Company and the initial investors in the Company, dated as of ____________, 2018 (the “Registration Rights Agreement”
and such registrable securities, the “Investor Securities”) as to which “piggy-back” registration
has been requested by the holders thereof, Pro Rata, that can be sold without exceeding the Maximum Number of Shares; and (iv) fourth,
to the extent that the Maximum Number of Shares have not been reached under the foregoing clauses (i), (ii), and (iii), the
Common Stock or other securities for the account of other persons that the Company is obligated to register pursuant to written
contractual arrangements with such persons and that can be sold without exceeding the Maximum Number of Shares.


 


5.1.5           Withdrawal.
If a majority-in-interest of the Demanding Holders disapprove of the terms of any underwriting or are not entitled to include all
of their Registrable Securities in any offering, such majority-in-interest of the Demanding Holders may elect to withdraw from
such offering by giving written notice to the Company and the underwriter or underwriters of their request to withdraw prior to
the effectiveness of the registration statement filed with the Commission with respect to such Demand Registration. If the majority-in-interest
of the Demanding Holders withdraws from a proposed offering relating to a Demand Registration, then the Company does not have to
continue its obligations under Section 5.1 with respect to such proposed offering.


 


5.1.6           Terms.
The Company shall bear all fees and expenses attendant to registering the Registrable Securities, including the
expenses of any legal counsel selected by the Holders to represent them in connection with the sale of the Registrable Securities,
but the Holders shall pay any and all underwriting commissions. The Company agrees to use its reasonable best efforts to qualify
or register the Registrable Securities in such states as are reasonably requested by the Majority Holder(s); provided, however,
that in no event shall the Company be required to register the Registrable Securities in a state in which such registration would
cause (i) the Company to be obligated to qualify to do business in such state, or would subject the Company to taxation as a foreign
corporation doing business in such jurisdiction or (ii) the principal stockholders of the Company to be obligated to escrow their
shares of Common Stock of the Company. The Company shall use its best efforts to cause any registration statement or post-effective
amendment filed pursuant to the demand rights granted under Section 5.1.1 to remain effective for a period of nine (9) consecutive
months from the effective date of such registration statement or post-effective amendment.

5.2         Piggy-Back
Registration.


 


5.2.1           Piggy-Back
Rights. If at any time during the seven (7) year period commencing on the Effective Date the Company proposes to file a registration
statement under the Act with respect to an offering of equity securities, or securities or other obligations exercisable or exchangeable
for, or convertible into, equity securities, by the Company for its own account or for stockholders of the Company for their account
(or by the Company and by stockholders of the Company including, without limitation, pursuant to Section 5.1), other than a registration
statement (i) filed in connection with any employee share option or other benefit plan, (ii) for an exchange offer or offering
of securities solely to the Company’s existing stockholders, (iii) for an offering of debt that is convertible into equity
securities of the Company or (iv) for a dividend reinvestment plan, then the Company shall (x) give written notice of such proposed
filing to the holders of Registrable Securities as soon as practicable but in no event less than ten (10) days before the anticipated
filing date, which notice shall describe the amount and type of securities to be included in such offering, the intended method(s)
of distribution, and the name of the proposed managing underwriter or underwriters, if any, of the offering, and (y) offer to
the holders of Registrable Securities in such notice the opportunity to register the sale of such number of shares of Registrable
Securities as such holders may request in writing within five (5) days following receipt of such notice (a “Piggy-Back
Registration”). The Company shall cause such Registrable Securities to be included in such registration and shall
use its best efforts to cause the managing underwriter or underwriters of a proposed underwritten offering to permit the Registrable
Securities requested to be included in a Piggy-Back Registration on the same terms and conditions as any similar securities of
the Company and to permit the sale or other disposition of such Registrable Securities in accordance with the intended method(s)
of distribution thereof. All holders of Registrable Securities proposing to distribute their securities through a Piggy-Back Registration
that involves an underwriter or underwriters shall enter into an underwriting agreement in customary form with the underwriter
or underwriters selected for such Piggy-Back Registration.


 


5.2.2           Reduction
of Offering. If the managing underwriter or underwriters for a Piggy-Back Registration that is to be an underwritten offering
advises the Company and the holders of Registrable Securities in writing that the dollar amount or number of shares of Common Stock
which the Company desires to sell, taken together with Common Stock, if any, as to which registration has been demanded pursuant
to written contractual arrangements with persons other than the holders of Registrable Securities hereunder, the Registrable Securities
as to which registration has been requested under this Section 5.2, and the Common Stock, if any, as to which registration has
been requested pursuant to the written contractual piggy-back registration rights of other stockholders of the Company, exceeds
the Maximum Number of Shares, then the Company shall include in any such registration:


 


(a)           If
the registration is undertaken for the Company’s account: (A) first, the Common Stock or other securities that the Company
desires to sell that can be sold without exceeding the Maximum Number of Shares; (B) second, to the extent that the Maximum
Number of Shares has not been reached under the foregoing clause (A), the Common Stock or other securities, if any, comprised

of Shares; (B) second, to the extent that the Maximum Number of Shares has not been reached under the foregoing clause (A),
the Common Stock or other securities that the Company desires to sell that can be sold without exceeding the Maximum Number of
Shares; (C) third, to the extent that the Maximum Number of Shares has not been reached under the foregoing clauses (A)
and (B), the shares of Registrable Securities, Pro Rata, as to which registration has been requested pursuant to the terms hereof,
that can be sold without exceeding the Maximum Number of Shares; and (D) fourth, to the extent that the Maximum Number of
Shares has not been reached under the foregoing clauses (A), (B) and (C), the Common Stock or other securities for the account
of other persons that the Company is obligated to register pursuant to written contractual arrangements with such persons, that
can be sold without exceeding the Maximum Number of Shares; and


 




    	 	 6	 



     


    

 


(c)           If
the registration is a Demand Registration undertaken at the demand of persons other than either the holders of Registrable Securities
or of Investor Securities, (A) first, the Common Stock or other securities for the account of the demanding persons that can be
sold without exceeding the Maximum Number of Shares; (B) second, to the extent that the Maximum Number of Shares has not been reached
under the foregoing clause (A), the Common Stock or other securities that the Company desires to sell that can be sold without
exceeding the Maximum Number of Shares; (C) third, to the extent that the Maximum Number of Shares has not been reached under the
foregoing clauses (A) and (B), collectively the Common Stock or other securities comprised of Registrable Securities and Investor
Securities, Pro Rata, as to which registration has been requested pursuant to the terms hereof and of the Registration Rights Agreement,
as applicable, that can be sold without exceeding the Maximum Number of Shares; and (D) fourth, to the extent that the Maximum
Number of Shares has not been reached under the foregoing clauses (A), (B) and (C), the Common Stock or other securities for the
account of other persons that the Company is obligated to register pursuant to written contractual arrangements with such persons,
that can be sold without exceeding the Maximum Number of Shares.


 


5.2.3           Withdrawal.
Any holder of Registrable Securities may elect to withdraw such holder’s request for inclusion of Registrable Securities
in any Piggy-Back Registration by giving written notice to the Company of such request to withdraw prior to the effectiveness
of the registration statement. The Company (whether on its own determination or as the result of a withdrawal by persons making
a demand pursuant to written contractual obligations) may withdraw a registration statement at any time prior to the effectiveness
of the registration statement. Notwithstanding any such withdrawal, the Company shall pay all expenses incurred by the holders
of Registrable Securities in connection with such Piggy-Back Registration as provided in Section 5.2.4.


 


5.2.4           Terms.
The Company shall bear all fees and expenses attendant to registering the Registrable Securities, including the
expenses of any legal counsel selected by the Holders to represent them in connection with the sale of the Registrable Securities
but the Holders shall pay any and all underwriting commissions related to the Registrable Securities. In the event of such a proposed
registration, the Company shall furnish the then Holders of outstanding Registrable Securities with not less than fifteen (15)
days written notice prior to the proposed date of filing of such registration statement. Such notice to the Holders shall continue
to be given for each applicable registration statement filed (during the period in which the Purchase Option is exercisable) by
the Company until such time as all of the Registrable Securities have been registered and sold. The Holders of the Registrable
Securities shall exercise the “piggy-back” rights provided for herein by giving written notice, within ten (10) days
of the receipt of the Company’s notice of its intention to file a registration statement. The Company shall use its best
efforts to cause any registration statement filed pursuant to the above “piggy-back” rights to remain effective for
at least nine (9) months from the date that the Holders of the Registrable Securities are first given the opportunity to sell all
of such securities.


 


5.3         General
Terms.


 


5.3.1           Indemnification.
The Company shall, to the fullest extent permitted by applicable law, indemnify the Holder(s) of the Registrable Securities to

arising out of any action between the underwriter and the Company or between the underwriter and any third party or otherwise)
to which any of them may become subject under the Act, the Exchange Act or otherwise, arising from such registration statement
but only to the same extent and with the same effect as the provisions pursuant to which the Company has agreed to indemnify the

any, who controls the Company within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, against all loss,
claim, damage, expense or liability (including all reasonable attorneys’ fees and other expenses reasonably incurred in investigating,
preparing or defending against any claim whatsoever) to which they may become subject under the Act, the Exchange Act or otherwise,
arising from information furnished by or on behalf of such Holders, or their successors or assigns, in writing, for specific inclusion
in such registration statement to the same extent and with the same effect as the provisions contained in Section 5 of the Underwriting

    	 	 7	 



     


    

 


5.3.2           Exercise

or the effectiveness thereof.


 


5.3.3           Documents
Delivered to Holders. The Company shall furnish EBC, as representative of the Holders participating in any of the foregoing
offerings, a signed counterpart, addressed to the participating Holders, of (i) an opinion of counsel to the Company, dated the
effective date of such registration statement (and, if such registration includes an underwritten public offering, an opinion dated
the date of the closing under any underwriting agreement related thereto), and (ii) if such registration statement is filed in
connection of an underwritten public offering, a “cold comfort” letter dated the effective date of such registration
statement (and, if such registration includes an underwritten public offering, a letter dated the date of the closing under the
underwriting agreement) signed by the independent public accountants who have issued a report on the Company’s financial
statements included in such registration statement, in each case covering substantially the same matters with respect to such registration
statement (and the prospectus included therein) and, in the case of such accountants’ letter, with respect to events subsequent
to the date of such financial statements, as are customarily covered in opinions of issuer’s counsel and in accountants’
letters delivered to underwriters in underwritten public offerings of securities. The Company shall also deliver promptly to EBC,
as representative of the Holders participating in the offering, the correspondence and memoranda described below and copies of
all correspondence between the Commission and the Company, its counsel or auditors and all memoranda relating to discussions with
the Commission or its staff with respect to the registration statement and permit EBC, as representative of the Holders, to do
such investigation, upon reasonable advance notice, with respect to information contained in or omitted from the registration statement
as it deems reasonably necessary to comply with applicable securities laws or rules of FINRA. Such investigation shall include
access to books, records and properties and opportunities to discuss the business of the Company with its officers and independent
auditors, all to such reasonable extent and at such reasonable times and as often as EBC, as representative of the Holders, shall
reasonably request. The Company shall not be required to disclose any confidential information or other records to EBC, as representative
of the Holders, or to any other person, until and unless such persons shall have entered into reasonable confidentiality agreements
(in form and substance reasonably satisfactory to the Company), with the Company with respect thereto.


 


5.3.4           Underwriting
Agreement. The Company shall enter into an underwriting agreement with the managing underwriter(s), if any, selected by any
Holders whose Registrable Securities are being registered pursuant to this Section 5, which managing underwriter shall be reasonably
acceptable to the Company. Such agreement shall be reasonably satisfactory in form and substance to the Company, each Holder and
such managing underwriters, and shall contain such representations, warranties and covenants by the Company and such other terms
as are customarily contained in agreements of that type used by the managing underwriter. The Holders shall be parties to any underwriting
agreement relating to an underwritten sale of their Registrable Securities and may, at their option, require that any or all the
representations, warranties and covenants of the Company to or for the benefit of such underwriters shall also be made to and for
the benefit of such Holders. Such Holders shall not be required to make any representations or warranties to or agreements with
the Company or the underwriters except as they may relate to such Holders and their intended methods of distribution. Such Holders,
however, shall agree to such covenants and indemnification and contribution obligations for selling stockholders as are customarily
contained in agreements of that type used by the managing underwriter. Further, such Holders shall execute appropriate custody
agreements and otherwise cooperate fully in the preparation of the registration statement and other documents relating to any offering
in which they include securities pursuant to this Section 5. Each Holder shall also furnish to the Company such information regarding
itself, the Registrable Securities held by it, and the intended method of disposition of such securities as shall be reasonably
required to effect the registration of the Registrable Securities.


 


5.3.5           Rule
144 Sale. Notwithstanding anything contained in this Section 5 to the contrary, the Company shall have no obligation pursuant to Sections
5.1 or 5.2 to use its best efforts to obtain the registration of Registrable Securities held by any Holder (i) where such Holder
would then be entitled to sell under Rule 144 within any three (3)-month period (or such other period prescribed under Rule 144
as may be provided by amendment thereof) all of the Registrable Securities then held by such Holder, and (ii) where the number
of Registrable Securities held by such Holder is within the volume limitations under paragraph (e) of Rule 144 (calculated as if
such Holder were an affiliate within the meaning of Rule 144).


 




    	 	 8	 



     


    

 


5.3.6           Supplemental
Prospectus. Each Holder agrees, that upon receipt of any notice from the Company of the happening of any event as a result
of which the prospectus included in the registration statement, as then in effect, includes an untrue statement of a material fact
or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light
of the circumstances then existing, such Holder will immediately discontinue disposition of Registrable Securities pursuant to
the registration statement covering such Registrable Securities until such Holder’s receipt of the copies of a supplemental
or amended prospectus, and, if so desired by the Company, such Holder shall deliver to the Company (at the expense of the Company)
or destroy (and deliver to the Company a certificate of such destruction) all copies, other than permanent file copies then in
such Holder’s possession, of the prospectus covering such Registrable Securities current at the time of receipt of such notice.


 


6.           Adjustments.


 


6.1         Adjustments
to Exercise Price and Number of Securities. The Exercise Price and the number of Units underlying the Purchase Option shall
be subject to adjustment from time to time as hereinafter set forth:


 


6.1.1           Share
Dividends - Split-Ups. If after the date hereof, and subject to the provisions of Section 6.3 below, the number of outstanding
shares of Common Stock is increased by a share dividend payable in Common Stock or by a split-up of Common Stock or other similar
event, then, on the effective date thereof, the number of shares of Common Stock underlying each of the Units purchasable hereunder
shall be increased in proportion to such increase in outstanding shares. In such case, the number of shares of Common Stock, and
the exercise price applicable thereto, underlying the Warrants underlying each of the Units purchasable hereunder shall be adjusted
in accordance with the terms of the Warrants.


 


6.1.2           Aggregation
of Shares. If after the date hereof, and subject to the provisions of Section 6.3, the number of outstanding shares of Common
Stock is decreased by a consolidation, combination or reclassification of Common Stock or other similar event, then, on the effective
date thereof, the number of shares of Common Stock underlying each of the Units purchasable hereunder shall be decreased in proportion
to such decrease in outstanding shares. In such case, the number of shares of Common Stock, and the exercise price applicable thereto,
underlying the Warrants underlying each of the Units purchasable hereunder shall be adjusted in accordance with the terms of the
Warrants.


 


6.1.3           Replacement
of Securities upon Reorganization, etc. In case of any reclassification or reorganization of the outstanding Common Stock other
than a change covered by Section 6.1.1 or 6.1.2 hereof or that solely affects the par value of such Common Stock, or in the case
of any merger or consolidation 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 reorganization of the outstanding Common
Stock), or in the case of any sale or conveyance to another corporation or entity of the property of the Company as an entirety
or substantially as an entirety in connection with which the Company is dissolved, the Holder of this Purchase Option shall have
the right thereafter (until the expiration of the right of exercise of this Purchase Option) to receive upon the exercise hereof,
for the same aggregate Exercise Price payable hereunder immediately prior to such event, the kind and amount of shares or other
securities or property (including cash) receivable upon such reclassification, reorganization, merger or consolidation, or upon
a dissolution following any such sale or transfer, by a Holder of the number of shares of Common Stock of the Company obtainable
upon exercise of this Purchase Option and the underlying Warrants immediately prior to such event; and if any reclassification
also results in a change in Common Stock covered by Section 6.1.1 or 6.1.2, then such adjustment shall be made pursuant to Sections
6.1.1, 6.1.2 and this Section 6.1.3. The provisions of this Section 6.1.3 shall similarly apply to successive reclassifications,
reorganizations, mergers or consolidations, sales or other transfers.


 




    	 	 9	 



     


    

 


6.1.4           Changes
in Form of Purchase Option. This form of Purchase Option need not be changed because of any change pursuant to this Section,
and Purchase Options issued after such change may state the same Exercise Price and the same number of Units as are stated in the
Purchase Options initially issued pursuant to this Agreement. The acceptance by any Holder of the issuance of new Purchase Options
reflecting a required or permissive change shall not be deemed to waive any rights to an adjustment occurring after the Commencement
Date or the computation thereof.


 


6.2         Substitute
Purchase Option. In case of any consolidation of the Company with, or merger of the Company with, or merger of the Company
into, another corporation (other than a consolidation or merger which does not result in any reclassification or change of the
outstanding Common Stock), the corporation formed by such consolidation or merger shall execute and deliver to the Holder a supplemental
Purchase Option providing that the holder of each Purchase Option then outstanding or to be outstanding shall have the right thereafter
(until the stated expiration of such Purchase Option) to receive, upon exercise of such Purchase Option, the kind and amount of
shares and other securities and property receivable upon such consolidation or merger, by a holder of the number of shares of Common
Stock of the Company for which such Purchase Option might have been exercised immediately prior to such consolidation, merger,
sale or transfer. Such supplemental Purchase Option shall provide for adjustments which shall be identical to the adjustments provided
in Section 6. The above provision of this Section shall similarly apply to successive consolidations or mergers.


 


6.3         Elimination
of Fractional Interests. The Company shall not be required to issue certificates representing fractions of shares of Common
Stock or Warrants upon the exercise of the Purchase Option, nor shall it be required to issue scrip or pay cash in lieu of any
fractional interests, it being the intent of the parties that all fractional interests shall be eliminated by rounding any fraction
up or down to the nearest whole number of Warrants or shares of Common Stock or other securities, properties or rights (or as otherwise
provided pursuant to the Warrants Agreement).


 


7.           Reservation
and Listing. The Company shall at all times reserve and keep available out of its authorized but unissued Common Stock, solely
for the purpose of issuance upon exercise of the Purchase Options or the Warrants underlying the Purchase Option, such number of
shares of Common Stock or other securities, properties or rights as shall be issuable upon the exercise thereof. The Company covenants
and agrees that, upon exercise of the Purchase Options and payment of the Exercise Price therefor, all shares of Common Stock and
other securities issuable upon such exercise shall be duly and validly issued, fully paid and non-assessable and not subject to
preemptive rights of any stockholder. The Company further covenants and agrees that upon exercise of the Warrants underlying the
Purchase Options and payment of the respective Warrant exercise price therefor, all shares of Common Stock and other securities
issuable upon such exercise shall be duly and validly issued, fully paid and non-assessable and not subject to preemptive rights
of any stockholder. As long as the Purchase Options shall be outstanding, the Company shall use its best efforts to cause all (i)
Units and Common Stock issuable upon exercise of the Purchase Options, (ii) Warrants issuable upon exercise of the Purchase Options
and (iii) Common Stock issuable upon exercise of the Warrants included in the Units issuable upon exercise of the Purchase Option
to be listed (subject to official notice of issuance) on all securities exchanges (or, if applicable on the OTC Bulletin Board
or any successor trading market) on which the Units, the Common Stock or the Public Warrants issued to the public in connection
herewith may then be listed and/or quoted.


 


8.           Certain
Notice Requirements.


 


8.1         Holder’s
Right to Receive Notice. Nothing herein shall be construed as conferring upon the Holders the right to vote or consent as a stockholder for
the election of directors or any other matter, or as having any rights whatsoever as a stockholder of the Company. If, however,
at any time prior to the expiration of the Purchase Options and their exercise, any of the events described in Section 8.2 shall
occur, then, in one or more of said events, the Company shall give written notice of such event at least fifteen (15) days prior
to the date fixed as a record date or the date of closing the transfer books for the determination of the stockholders entitled
to such dividend, distribution, conversion or exchange of securities or subscription rights, or entitled to vote on such proposed
dissolution, liquidation, winding up or sale. Such notice shall specify such record date or the date of the closing of the transfer
books, as the case may be. Notwithstanding the foregoing, the Company shall deliver to each Holder a copy of each notice given
to the other stockholders of the Company at the same time and in the same manner that such notice is given to the stockholders.

Requiring Notice. The Company shall be required to give the notice described in this Section 8 upon one or more of the following
events: (i) if the Company shall take a record of the holders of its Common Stock for the purpose of entitling them to receive
a dividend or distribution payable otherwise than in cash, or a cash dividend or distribution payable otherwise than out of retained
earnings, as indicated by the accounting treatment of such dividend or distribution on the books of the Company, or (ii) the Company
shall offer to all the holders of its Common Stock any additional shares of the Company or securities convertible into or exchangeable
for shares of the Company, or any option, right or warrant to subscribe therefor, or (iii) a dissolution, liquidation or winding
up of the Company (other than in connection with a consolidation or merger) or a sale of all or substantially all of its property,
assets and business shall be proposed.


 


8.3         Notice
of Change in Exercise Price. The Company shall, promptly after an event requiring a change in the Exercise Price pursuant
to Section 6 hereof, send notice to the Holders of such event and change (“Price Notice”). The Price
Notice shall describe the event causing the change and the method of calculating the change and shall be certified as being true
and accurate by the Company’s President and Chief Financial Officer.


 


8.4         Transmittal
of Notices. All notices, requests, consents and other communications under this Purchase Option shall be in writing and shall
be deemed to have been duly made when hand delivered, or mailed by express mail or private courier service: (i) if to the registered

9.6         Waiver,
