Exhibit 4.1


 


CERTIFICATE OF DESIGNATION OF

SERIES B CONVERTIBLE PREFERRED STOCK


OF BIOHITECH GLOBAL, INC.


 


BioHiTech Global, Inc.,
a corporation organized and existing under the laws of the State of Delaware ("Company"), hereby certifies that
the Board of Directors of the Company (the "Board of Directors" or the "Board"), pursuant to
authority of the Board of Directors as required by applicable corporate law, and in accordance with the provisions of its certificate
of incorporation and bylaws, has and hereby authorizes a series of the Company's previously authorized Preferred Stock, par value
$0.0001 per share (the "Preferred Stock"), and hereby states the designation and number of shares, and fixes the
rights, preferences, privileges, powers and restrictions thereof, as follows: 


 


1.             Designation
and Number of Shares. There shall hereby be created and established a series of preferred stock of the Company designated as
“Series B Convertible Preferred Stock” (the “Preferred Shares”). The authorized number of Preferred
Shares shall be one million one hundred eleven thousand two hundred (1,111,200) shares. Each Preferred Share shall have a par value
of $0.0001. Capitalized terms not defined herein shall have the meanings as set forth in Section 23 below.


 


2.             Ranking.
The Preferred Shares shall rank junior to any existing and future Indebtedness or series of preferred stock of senior rank to the
Preferred Shares, including a yet to be designated class of Series C Convertible Preferred Stock; in respect of the preferences
as to dividends, distributions and payments upon the liquidation, dissolution and winding-up of the Company (collectively, the
“Senior Securities”) or any future series of existing Indebtedness or preferred stock of pari passu rank to
the Preferred Shares in respect of the preferences as to dividends, distributions and payments upon the liquidation, dissolution
and winding-up of the Company (collectively, the “Parity Stock”), all shares of capital stock of the Company
shall be junior in rank to all Preferred Shares with respect to the preferences as to dividends, distributions and payments upon
the liquidation, dissolution and winding-up of the Company (collectively, the “Junior Stock”). The rights of
all such shares of capital stock of the Company shall be subject to the rights, powers, preferences and privileges of the Preferred
Shares. In the event of the merger or consolidation of the Company with or into another corporation, the Preferred Shares shall
maintain their relative rights, powers, preferences, privileges, and designations provided for herein and no such merger or consolidation
shall result inconsistent therewith.


 


3.             Dividends.


 


(a)           From
and after the date of issuance of any Preferred Shares (the “Initial Issuance Date”), each holder of such Preferred
Shares (each, a “Holder” and collectively, the “Holders”) shall be entitled to receive dividends
(the “Dividends”), which Dividends shall be paid by the Company out of funds legally available therefor, payable,
subject to the conditions and other terms hereof, in shares of Common Stock or cash on the Stated Value of such Preferred Shares
at the Dividend Rate which shall be cumulative and shall continue to accrue whether or not declared and whether or not in any fiscal
year there shall be net profits or surplus available for the payment of dividends in such fiscal year. Dividends on the Preferred
Shares shall commence accumulating on the Initial Issuance Date and shall be computed on the basis of a 365-day year and actual
days elapsed. Subject to Section 4(c), Dividends shall be payable on the Maturity Date (the “Dividend Date”).
If the Dividend Date is not a Business Day (as defined below), then the Dividend shall be due and payable on the Business Day immediately
following such Dividend Date.


 




    	 	1	 



     


    

 


(b)           Dividends
shall be payable on the Dividend Date, to the Holders of record of the Preferred Shares on the applicable Dividend Date, in shares
of Common Stock (the “Dividend Shares”) so long as there has been no Equity Conditions Failure and so long as
the delivery of Dividend Shares would not violate the provisions of Section 4(e); provided, however, that the Company
may, at its option, pay Dividends on any Dividend Date in cash (the “Cash Dividends”) or in a combination of
Cash Dividends and, so long as there has been no Equity Conditions Failure, Dividend Shares. The Company shall deliver a written
notice (each, a “Dividend Election Notice”) to each Holder on the Dividend Notice Due Date (the date such notice
is delivered to all of the Holders, the “Dividend Notice Date”), which notice (1) either (A) confirms that Dividends
to be paid on such Dividend Date shall be paid entirely in Dividend Shares or (B) elects to pay Dividends as Cash Dividends, Dividend
Shares, or as a combination of Dividend Shares and Cash Dividends and, in any event, specifies the amount of Dividends that shall
be paid as Cash Dividends and the amount of Dividends, if any, that shall be paid in Dividend Shares and (2) certifies that there
has been no Equity Conditions Failure as of such time, if any portion of the Dividends shall be paid in Dividend Shares. Notwithstanding
anything herein to the contrary, if no Equity Conditions Failure has occurred as of the Dividend Notice Date but an Equity Conditions
Failure occurs at any time prior to the Dividend Date, (A) the Company shall provide each Holder a subsequent notice to that effect
and (B) unless such Holder waives the Equity Conditions Failure, the Dividend payable to such Holder on such Dividend Date shall
be paid as Cash Dividends to be paid to each Holder on a Dividend Date in Dividend Shares shall be paid in a number of fully paid
and non-assessable shares (rounded to the nearest whole share, with 0.50 or more of a share being rounded up to the nearest whole
share and 0.49 or less of a share being rounded down to the nearest whole share) of Common Stock equal to the quotient of (1) the
amount of Dividends payable to such Holder on such Dividend Date less any Cash Dividends paid and (2) the Conversion Price in effect
on the applicable Dividend Date.


 


(c)           When
any Dividend Shares are to be paid on a Dividend Date to any Holder, the Company shall (i) (A) provided that (x) the Company’s
transfer agent (the “Transfer Agent”) is participating in the Depository Trust Company (“DTC”)
Fast Automated Securities Transfer Program and (y) such Dividend Shares to be so issued are eligible for resale pursuant to Rule
144 (as defined in the Securities Purchase Agreement), credit such aggregate number of Dividend Shares to which such Holder shall
be entitled to such Holder’s or its designee’s balance account with DTC through its Deposit and Withdrawal at Custodian
system, or (B) if either of the immediately preceding clauses (x) or (y) is not satisfied, issue and deliver on the applicable
Dividend Date, to the address set forth in the register maintained by the Company for such purpose pursuant to the Securities Purchase
Agreement or to such address as specified by such Holder in writing to the Company at least two (2) Business Days prior to the
applicable Dividend Date, a certificate, registered in the name of such Holder or its designee, for the number of Dividend Shares
to which such Holder shall be entitled and (ii) with respect to each Dividend Date, pay to such Holder, in cash by wire transfer
of immediately available funds, the amount of any Cash Dividend. The Company shall pay any and all taxes that may be payable with
respect to the issuance and delivery of Dividend Shares.

4.            Conversion.
Each Preferred Share shall be convertible into validly issued, fully paid and non-assessable shares of Common Stock (as defined
below) on the terms and conditions set forth in this Section 4.


 


(a)           Holder’s
Conversion Right. Subject to the provisions of Section 4(e), at any time or times after the Initial Issuance Date (the “Initial
Conversion Date”) each Holder shall be entitled to convert any whole number of Preferred Shares into validly issued,
fully paid and non-assessable shares of Common Stock in accordance with Section 4(d) at the Conversion Rate (as defined below).


 


(b)           Mandatory
Redemption. On the Mandatory Redemption Date, the Preferred Shares shall automatically convert into validly issued, fully paid
and non-assessable shares of Common Stock in accordance with Section 4(d) at the Conversion Rate (as defined below).


 


(c)           Conversion
Rate. The number of validly issued, fully paid and non-assessable shares of Common Stock issuable upon conversion (the “Conversion
Shares”) of each Preferred Share pursuant to Section 4(a) shall be determined according to the following formula (the
“Conversion Rate”):


 


Conversion Amount

Conversion Price


 


No fractional
shares of Common Stock are to be issued upon the conversion of any Preferred Shares. If the issuance would result in the issuance
of a fraction of a share of Common Stock, the Company shall round such fraction of a share of Common Stock up to the nearest whole
share.


 


(d)           Mechanics
of Conversion. The conversion of each Preferred Share shall be conducted in the following manner:


 


(i)          Holder’s
Conversion. Subject to the provisions of Section 4(f), to convert Preferred Shares into validly issued, fully paid and non-assessable
shares of Common Stock on any date (a “Conversion Date”), a Holder shall deliver (via electronic mail), for
receipt on or prior to 11:59 p.m., New York time, on such date, a copy of an executed notice of conversion of Preferred Shares
subject to such conversion in the form attached hereto as Exhibit A (the “Conversion Notice”)
to the Company, which Conversion Notice shall be subject to an adjustment pursuant to Section 8 to the Conversion Price set forth
on such Conversion Notice upon the close of the Principal Market on the Conversion Date. If required by Section 4(d)(vi), within
three (3) Trading Days following a conversion of any such Preferred Shares as aforesaid, such Holder shall surrender to a nationally
recognized overnight delivery service for delivery to the Company the original certificates representing the share(s) of Preferred
Shares (the “Preferred Share Certificates”) so converted as aforesaid.


 




    	 	3	 



     


    

 


(ii)         Company’s
Response. On or before the first (1st) Trading Day following the date of receipt of a Conversion Notice, the Company
shall transmit by facsimile or electronic mail an acknowledgment of confirmation, in the form attached hereto as Exhibit
B, of receipt of such Conversion Notice to such Holder and the Transfer Agent, which confirmation shall constitute an instruction
to the Transfer Agent to process such Conversion Notice in accordance with the terms herein. On or before the second (2nd)
Trading Day following the date of receipt by the Company of such Conversion Notice, the Company shall (1) provided that (x) the
Transfer Agent is participating in DTC Fast Automated Securities Transfer Program and (y) such Conversion Shares and Dividend Shares
(as applicable) to be so issued are eligible for resale pursuant to Rule 144 credit such aggregate number of Conversion Shares
and Dividend Shares (as applicable) to which such Holder shall be entitled to such Holder’s or its designee’s balance
account with DTC through its Deposit/Withdrawal at Custodian system, or (2) if either of the immediately preceding clauses (x)
or (y) are not satisfied, issue and deliver (via reputable overnight courier) to the address as specified in such Conversion Notice,
a certificate, registered in the name of such Holder or its designee, for the number of Conversion Shares and Dividend Shares (as
applicable) to which such Holder shall be entitled. If the number of Preferred Shares represented by the Preferred Share Certificate(s)
submitted for conversion pursuant to Section 4(c)(vi) is greater than the number of Preferred Shares being converted, then the
Company shall if requested by such Holder, as soon as practicable and in no event later than three (3) Trading Days after receipt
of the Preferred Share Certificate(s) and at its own expense, issue and deliver to such Holder (or its designee) a new Preferred
Share Certificate representing the number of Preferred Shares not converted.


 


(iii)        Record
Holder. The Person or Persons entitled to receive the shares of Common Stock issuable upon a conversion of Preferred Shares
shall be treated for all purposes as the record holder or holders of such shares of Common Stock on the Conversion Date.


 




    	 	4	 



     


    

 


 


(iv)        Company’s
Failure to Timely Convert. If the Company shall fail, for any reason or for no reason, to issue to a Holder within three (3)
Trading Days after the Company’s receipt of a Conversion Notice (whether via facsimile or otherwise) (the “Share
Delivery Deadline”), a certificate for the number of shares of Common Stock to which such Holder is entitled and register
such shares of Common Stock on the Company’s share register or to credit such Holder’s or its designee’s balance
account with DTC for such number of shares of Common Stock to which such Holder is entitled upon such Holder’s conversion
of any Preferred Shares (as the case may be) (a “Conversion Failure”), then, in addition to all other remedies
available to such Holder, such Holder, upon written notice to the Company, may void its Conversion Notice with respect to, and
retain or have returned (as the case may be) any Preferred Shares that have not been converted pursuant to such Holder’s
Conversion Notice, provided that the voiding of a Conversion Notice shall not affect the Company’s obligations to make any
payments which have accrued prior to the date of such notice pursuant to the terms of this Certificate of Designation or otherwise.
In addition to the foregoing, if within two (2) Trading Days after the Company’s receipt of a Conversion Notice (whether
via facsimile or otherwise), the Company shall fail to issue and deliver a certificate to such Holder and register such shares
of Common Stock on the Company’s share register or credit such Holder’s or its designee’s balance account with
DTC for the number of Conversion Shares and Dividend Shares (as applicable) to which such Holder is entitled upon such Holder’s
conversion hereunder (as the case may be), and if on or after such second (2nd) Trading Day such Holder (or any other
Person in respect, or on behalf, of such Holder) purchases (in an open market transaction or otherwise) shares of Common Stock
to deliver in satisfaction of a sale by such Holder of all or any portion of the number of shares of Common Stock, or a sale of
a number of shares of Common Stock equal to all or any portion of the number of shares of Common Stock, issuable upon such conversion
that such Holder so anticipated receiving from the Company, then, in addition to all other remedies available to such Holder, the
Company shall, within three (3) Business Days after such Holder’s request, which request shall include reasonable documentation
of all fees, costs and expenses, and in such Holder’s discretion, either (i) pay cash to such Holder in an amount equal to
such Holder’s total purchase price (including brokerage commissions and other out-of-pocket expenses, if any) for the shares
of Common Stock so purchased (including, without limitation, by any other Person in respect, or on behalf, of such Holder) (the
“Buy-In Price”), at which point the Company’s obligation to so issue and deliver such certificate or credit
such Holder’s balance account with DTC for the number of shares of Common Stock to which such Holder is entitled upon such
Holder’s conversion hereunder (as the case may be) (and to issue such shares of Common Stock) shall terminate, or (ii) promptly
honor its obligation to so issue and deliver to such Holder a certificate or certificates representing such shares of Common Stock
or credit such Holder’s balance account with DTC for the number of shares of Common Stock to which such Holder is entitled
upon such Holder’s conversion hereunder (as the case may be) and pay cash to such Holder in an amount equal to the excess
(if any) of the Buy-In Price over the product of (A) such number of shares of Common Stock multiplied by (B) the lowest Closing
Sale Price of the Common Stock on any Trading Day during the period commencing on the date of the applicable Conversion Notice
and ending on the date of such issuance and payment under this clause (ii). Immediately following the voiding of a Conversion Notice
as aforesaid, the Conversion Price of any Preferred Shares returned or retained by such Holder for failure to timely convert shall
be adjusted to the lesser of (I) the Conversion Price relating to the voided Conversion Notice and (II) the lowest average VWAP
of the Common Stock during the period beginning on the Conversion Date and ending on the date such Holder voided the Conversion
Notice, subject to further adjustment as provided in this Certificate of Designation.


 




    	 	5	 



     


    

 


(v)         Pro
Rata Conversion; Disputes. In the event the Company receives a Conversion Notice from more than one Holder for the same Conversion
Date and the Company can convert some, but not all, of such Preferred Shares submitted for conversion, the Company shall convert
from each Holder electing to have Preferred Shares converted on such date a pro rata amount of such Holder’s Preferred Shares
submitted for conversion on such date based on the number of Preferred Shares submitted for conversion on such date by such Holder
relative to the aggregate number of Preferred Shares submitted for conversion on such date. In the event of a dispute as to the
number of shares of Common Stock issuable to a Holder in connection with a conversion of Preferred Shares, the Company shall issue
to such Holder the number of shares of Common Stock not in dispute and resolve such dispute in accordance with Section 22.


 


(vi)        Book-Entry.
Notwithstanding anything to the contrary set forth in this Section 4, upon conversion of any Preferred Shares in accordance with
the terms hereof, no Holder thereof shall be required to physically surrender the certificate representing the Preferred Shares
to the Company following conversion thereof unless (A) the full or remaining number of Preferred Shares represented by the certificate
are being converted (in which event such certificate(s) shall be delivered to the Company as contemplated by this Section 4(d)(vi))
or (B) such Holder has provided the Company with prior written notice (which notice may be included in a Conversion Notice) requesting
reissuance of Preferred Shares upon physical surrender of any Preferred Shares. Each Holder and the Company shall maintain records
showing the number of Preferred Shares so converted by such Holder and the dates of such conversions or shall use such other method,
reasonably satisfactory to such Holder and the Company, so as not to require physical surrender of the certificate representing
the Preferred Shares upon each such conversion. A Holder and any transferee or assignee, by acceptance of a certificate, acknowledge
and agree that, by reason of the provisions of this paragraph, following conversion of any Preferred Shares, the number of Preferred
Shares represented by such certificate may be less than the number of Preferred Shares stated on the face thereof. Each certificate
for Preferred Shares shall bear the following legend:


 


ANY TRANSFEREE OR ASSIGNEE OF THIS
CERTIFICATE SHOULD CAREFULLY REVIEW THE TERMS OF THE COMPANY’S CERTIFICATE OF DESIGNATION RELATING TO THE SHARES OF SERIES
B PREFERRED STOCK REPRESENTED BY THIS CERTIFICATE, INCLUDING SECTION 4(c)(vi) THEREOF. THE NUMBER OF SHARES OF SERIES B PREFERRED
STOCK REPRESENTED BY THIS CERTIFICATE MAY BE LESS THAN THE NUMBER OF SHARES OF SERIES B PREFERRED STOCK STATED ON THE FACE HEREOF
PURSUANT TO SECTION 4(c)(vi) OF THE CERTIFICATE OF DESIGNATION RELATING TO THE SHARES OF SERIES B PREFERRED STOCK REPRESENTED BY
THIS CERTIFICATE.


 




    	 	6	 



     


    

 


(e)           Taxes.
The Company shall pay any and all documentary, stamp, transfer (but only in respect of the registered holder thereof), issuance
and other similar taxes that may be payable with respect to the issuance and delivery of shares of Common Stock upon the conversion
of Preferred Shares.


 


(f)            Limitation
on Beneficial Ownership.


 


(i)          Notwithstanding
anything to the contrary contained in this Certificate of Designation, the Preferred Shares held by a Holder shall not be convertible
by such Holder, and the Company shall not affect any conversion of any Preferred Shares held by such Holder, to the extent (but
only to the extent) that such Holder or any of its affiliates would beneficially own in excess of 4.99% (the “Maximum
Percentage”) of the then issued and outstanding shares of Common Stock. To the extent the above limitation applies,
the determination of whether the Preferred Shares held by such Holder shall be convertible (vis-à-vis other convertible,
exercisable or exchangeable securities owned by such Holder or any of its affiliates) and of which such securities shall be convertible,
exercisable or exchangeable (as among all such securities owned by such Holder and its affiliates) shall, subject to such Maximum
Percentage limitation, be determined on the basis of the first submission to the Company for conversion, exercise or exchange (as
the case may be). No prior inability of a Holder to convert Preferred Shares, or of the Company to issue shares of Common Stock
to such Holder, pursuant to this Section 4(f) shall have any effect on the applicability of the provisions of this Section 4(f) with
respect to any subsequent determination of convertibility or issuance (as the case may be). For purposes of this Section 4(f),
beneficial ownership and all determinations and calculations (including, without limitation, with respect to calculations of percentage
ownership) shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder.
The provisions of this Section 4(f) shall be implemented in a manner otherwise in strict conformity with the terms of this Section
4(f) to correct this Section 4(f) (or any portion hereof) which may be defective or inconsistent with the intended Maximum Percentage
beneficial ownership limitation herein contained or to make changes or supplements necessary or desirable to properly give effect
to such Maximum Percentage limitation. The limitations contained in this Section 4(f) shall apply to a successor holder of Preferred
Shares. For any reason at any time, upon the written or oral request of a Holder, the Company shall within one (1) Business Day
confirm orally and in writing to such Holder the number of shares of Common Stock then outstanding, including by virtue of any
prior conversion or exercise of convertible or exercisable securities into Common Stock, including, without limitation, pursuant
to this Certificate of Designation or securities issued pursuant to the other Transaction Documents (as defined in the Securities
Purchase Agreement). Notwithstanding anything to the contrary contained herein, by written notice to the Company, any Holder may
increase or decrease the Maximum Percentage to any other percentage not in excess of 9.99% specified in such notice; provided that
(i) any such increase will not be effective until the 61st day after such notice is delivered to the Company, and (ii)
any such increase or decrease will apply only to such Holder sending such notice and not to any other Holder.


 




    	 	7	 



     


    

 


Notwithstanding
anything contained in this Section 4(f) to the contrary, the Holder may, at its option and in its sole discretion, determine (A)
whether the Preferred Shares held by such Holder shall be convertible (vis-à-vis other convertible, exercisable or exchangeable
securities owned by such Holder or any of its affiliates) and (B) of which such securities shall be convertible, exercisable or
exchangeable (as among all such securities owned by such Holder and its affiliates) on any basis, order, or amounts for conversion,
exercise or exchange (as the case may be).


 


(ii)         Principal
Market Regulation. Notwithstanding anything herein to the contrary, the Company shall not issue any shares of Common Stock
upon conversion of any Preferred Shares or otherwise pursuant to this Certificate of Designation, until the Company obtains the
Stockholder Approval, if and to the extent such Stockholder Approval is necessary for such issuance.


 


(g)           Anti-Dilution.
If, at any time while the Preferred Shares are outstanding, the Company sells or grants any option to purchase or sells or grants
any right to reprice, or otherwise disposes of or issues, any Common Stock or Common Stock Equivalents entitling any Person to
acquire shares of Common Stock at or with a conversion formula that creates an effective price per share that is lower than the
then Conversion Price (such lower price or conversion formula, the “Base Conversion Price” and such issuances, collectively,
a “Dilutive Issuance”) (if the holder of the Common Stock or Common Stock Equivalents so issued shall at any time,
whether by operation of purchase price adjustments, reset provisions, floating conversion, exercise or exchange prices or otherwise,
or due to warrants, options or rights per share which are issued in connection with such issuance, be entitled to receive shares
of Common Stock at an effective price per share that is lower than the Conversion Price, such issuance shall be deemed to have
occurred for less than the Conversion Price on such date of the Dilutive Issuance), then the Conversion Price shall be reduced
to equal the Base Conversion Price. Such adjustment shall be made whenever such Common Stock or Common Stock Equivalents are issued.
Notwithstanding the foregoing, no adjustment will be made under this Section 4(g) in respect of an Exempt Issuance. The Company
shall notify the Holders in writing, no later than the Trading Day following the issuance of any Common Stock or Common Stock Equivalents
subject to this Section 4(g), indicating therein the applicable issuance price, or applicable reset price, exchange price, conversion
price, conversion formula and other pricing terms (such notice, the “Dilutive Issuance Notice”). For the avoidance
of doubt, whether or not the Company provides a Dilutive Issuance Notice pursuant to this Section 4(g), upon the occurrence of
any Dilutive Issuance, the Holders will be entitled to receive a number of Conversion Shares based upon the Base Conversion Price
on or after the date of such Dilutive Issuance, regardless of whether the Holder accurately refers to the Base Conversion Price
in the Notice of Conversion.

5.             Reserved.


 


6.             Rights
Upon Fundamental Transactions. The Company shall not enter into or be party to a Fundamental Transaction unless (i) the Successor
Entity assumes in writing all of the obligations of the Company under this Certificate of Designation and the other Transaction
Documents in accordance with the provisions of this Section 6 pursuant to written agreements in form and substance satisfactory
to the Required Holders and approved by the Required Holders prior to such Fundamental Transaction, including agreements to deliver
to each holder of Preferred Shares in exchange for such Preferred Shares a security of the Successor Entity evidenced by a written
instrument substantially similar in form and substance to this Certificate of Designation, including, without limitation, having
a Stated Value and Dividend Rate equal to the stated value and dividend rate of the Preferred Shares held by the Holders and having
similar ranking to the Preferred Shares, and reasonably satisfactory to the Required Holders and (ii) the Successor Entity
(including its Parent Entity) is a publicly traded corporation whose shares of common stock are quoted on or listed for trading
on an Eligible Market. Upon the occurrence of any Fundamental Transaction, the Successor Entity shall succeed to, and be substituted
for (so that from and after the date of such Fundamental Transaction, the provisions of this Certificate of Designation and the
other Transaction Documents referring to the “Company” shall refer instead to the Successor Entity), and may exercise
every right and power of the Company and shall assume all of the obligations of the Company under this Certificate of Designation
and the other Transaction Documents with the same effect as if such Successor Entity had been named as the Company herein and therein.
In addition to the foregoing, upon consummation of a Fundamental Transaction, the Successor Entity shall deliver to each Holder
confirmation that there shall be issued upon conversion of the Preferred Shares at any time after the consummation of such Fundamental
Transaction, in lieu of the shares of Common Stock (or other securities, cash, assets or other property (except such items still
issuable under Sections 7(a) and 12, which shall continue to be receivable thereafter)) issuable upon the conversion of the Preferred
Shares prior to such Fundamental Transaction, such shares of publicly traded common stock (or their equivalent) of the Successor
Entity (including its Parent Entity) which each Holder would have been entitled to receive upon the consummation of such Fundamental
Transaction had all the Preferred Shares held by each Holder been converted immediately prior to such Fundamental Transaction (without
regard to any limitations on the conversion of the Preferred Shares contained in this Certificate of Designation), as adjusted
in accordance with the provisions of this Certificate of Designation. The provisions of this Section 6 shall apply similarly and
equally to successive Fundamental Transactions and shall be applied without regard to any limitations on the conversion of the
Preferred Shares.





 




    	 	9	 



     


    

 


7.             Rights
Upon Issuance of Purchase Rights and Other Corporate Events.


 


(a)          Purchase
Rights. In addition to any adjustments pursuant to Section 8 below, if at any time the Company grants, issues or sells any
Options, Convertible Securities or rights to purchase stock, warrants, securities or other property pro rata to the record holders
of any class of Common Stock (the “Purchase Rights”), then each Holder will be entitled to acquire, upon the
terms applicable to such Purchase Rights, the aggregate Purchase Rights which such Holder could have acquired if such Holder had
held the number of shares of Common Stock acquirable upon complete conversion of all the Preferred Shares (without taking into
account any limitations or restrictions on the convertibility of the Preferred Shares) held by such Holder immediately before the
date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date
as of which the record holders of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights (provided,
however, to the extent that such Holder’s right to participate in any such Purchase Right would result in such Holder exceeding
the Maximum Percentage, then such Holder shall not be entitled to participate in such Purchase Right to such extent (or beneficial
ownership of such shares of Common Stock as a result of such Purchase Right to such extent) and such Purchase Right to such extent
shall be held in abeyance for such Holder until such time, if ever, as its right thereto would not result in such Holder exceeding
the Maximum Percentage).


 


(b)          Other
Corporate Events. In addition to and not in substitution for any other rights hereunder, prior to the consummation of any Fundamental
Transaction pursuant to which holders of shares of Common Stock are entitled to receive securities or other assets with respect
to or in exchange for shares of Common Stock (a “Corporate Event”), the Company shall make appropriate provision
to insure that each Holder will thereafter have the right to receive upon a conversion of all the Preferred Shares held by such
Holder (i) in addition to the shares of Common Stock receivable upon such conversion, such securities or other assets to which
such Holder would have been entitled with respect to such shares of Common Stock had such shares of Common Stock been held by such
Holder upon the consummation of such Corporate Event (without taking into account any limitations or restrictions on the convertibility
of the Preferred Shares contained in this Certificate of Designation) or (ii) in lieu of the shares of Common Stock otherwise receivable
upon such conversion, such securities or other assets received by the holders of shares of Common Stock in connection with the
consummation of such Corporate Event in such amounts as such Holder would have been entitled to receive had the Preferred Shares
held by such Holder initially been issued with conversion rights for the form of such consideration (as opposed to shares of Common
Stock) at a conversion rate for such consideration commensurate with the Conversion Rate. The provisions of this Section 7 shall
apply similarly and equally to successive Corporate Events and shall be applied without regard to any limitations on the conversion
of the Preferred Shares contained in this Certificate of Designation.


 




    	 	10	 



     


    

 


8.            Adjustment
of Conversion Price upon Subdivision or Combination of Common Stock. Without limiting any provision of Section 7 or Section
12, if the Company at any time on or after the First Closing subdivides (by any stock split, stock dividend, recapitalization or
otherwise) one or more classes of its outstanding shares of Common Stock into a greater number of shares, the Conversion Price
in effect immediately prior to such subdivision will be proportionately reduced. Without limiting any provision of Section 7 or
Section 12, if the Company at any time on or after the First Closing combines (by combination, reverse stock split or otherwise)
one or more classes of its outstanding shares of Common Stock into a smaller number of shares, the Conversion Price in effect immediately
prior to such combination will be proportionately increased. Any adjustment pursuant to this Section 8 shall become effective immediately
after the effective date of such subdivision or combination. If any event requiring an adjustment under this Section 8 occurs during
the period that a Conversion Price is calculated hereunder, then the calculation of such Conversion Price shall be adjusted appropriately
to reflect such event.


 


9.            Authorized
Shares.


 


(a)          Reservation.
The Company shall initially reserve out of its authorized and unissued Common Stock a number of shares of Common Stock equal to
100% of the Conversion Rate with respect to the Conversion Amount of each Preferred Share as of the Initial Issuance Date (assuming
for purposes hereof, that all the Preferred Shares issuable pursuant to the Securities Purchase have been issued, such Preferred
Shares are convertible at the Conversion Price and without taking into account any limitations on the conversion of such Preferred
Shares set forth in herein) (assuming for purposes hereof, that all the Preferred Shares issuable pursuant to the Securities Purchase
Agreement have been issued and without taking into account any limitations on the issuance of securities set forth herein). So
long as any of the Preferred Shares are outstanding, the Company shall take all action necessary to reserve and keep available
out of its authorized and unissued shares of Common Stock, solely for the purpose of effecting the conversion of the Preferred
Shares, as of any given date, 100% of the number of shares of Common Stock as shall from time to time be necessary to effect the
conversion of all of the Preferred Shares issued or issuable pursuant to the Securities Purchase Agreement assuming for purposes
hereof, that all the Preferred Shares issuable pursuant to the Securities Purchase Agreement have been issued and without taking
into account any limitations on the issuance of securities set forth herein, provided that at no time shall the number of shares
of Common Stock so available be less than the number of shares required to be reserved by the previous sentence (without regard
to any limitations on conversions contained in this Certificate of Designation) (the “Required Amount”). The
initial number of shares of Common Stock reserved for conversions of the Preferred Shares and each increase in the number of shares
so reserved shall be allocated pro rata among the Holders based on the number of Preferred Shares held by each Holder on the Initial
Issuance Date or increase in the number of reserved shares (as the case may be) (the “Authorized Share Allocation”).
In the event a Holder shall sell or otherwise transfer any of such Holder’s Preferred Shares, each transferee shall be allocated
a pro rata portion of such Holder’s Authorized Share Allocation. Any shares of Common Stock reserved and allocated to any
Person which ceases to hold any Preferred Shares shall be allocated to the remaining Holders of Preferred Shares, pro rata based
on the number of Preferred Shares then held by such Holders.

(b)          Insufficient
Authorized Shares. If, notwithstanding Section 9(a) and not in limitation thereof, at any time while any of the Preferred Shares
remain outstanding the Company does not have a sufficient number of authorized and unissued shares of Common Stock to satisfy its
obligation to have available for issuance upon conversion of the Preferred Shares at least a number of shares of Common Stock equal
to the Required Amount (an “Authorized Share Failure”), then the Company shall immediately take all action necessary
to increase the Company’s authorized shares of Common Stock to an amount sufficient to allow the Company to reserve and have
available the Required Amount for all of the Preferred Shares then outstanding. Without limiting the generality of the foregoing
sentence, as soon as practicable after the date of the occurrence of an Authorized Share Failure, but in no event later than ninety
(90) days after the occurrence of such Authorized Share Failure, the Company shall hold a meeting or obtain written consent of
its stockholders for the approval of an increase in the number of authorized shares of Common Stock. In connection with such meeting,
the Company shall provide each stockholder with a proxy statement or information statement, as applicable, and shall use its best
efforts to solicit its stockholders’ approval of such increase in authorized shares of Common Stock and to cause its Board
to recommend to the stockholders that they approve such proposal.


 


10.           Voting
Rights. Holders of Preferred Shares shall have no voting rights, except as required by law (including, without limitation,
the DGCL) and as expressly provided in this Certificate of Designation. To the extent that under the DGCL the vote of the holders
of the Preferred Shares, voting separately as a class or series as applicable, is required to authorize a given action of the Company,
the affirmative vote or consent of the holders of two-thirds of the Preferred Shares, voting together in the aggregate and not
in separate series unless required under the DGCL, represented at a duly held meeting at which a quorum is presented or by written
consent of all of the Preferred Shares (except as otherwise may be required under the DGCL), voting together in the aggregate and
not in separate series unless required under the DGCL, shall constitute the approval of such action by both the class or the series,
as applicable. Subject to Section 4(f), to the extent that under the DGCL holders of the Preferred Shares are entitled to vote
on a matter with holders of shares of Common Stock, voting together as one class, each Preferred Share shall entitle the holder
thereof to cast that number of votes per share as is equal to the number of shares of Common Stock into which it is then convertible
(subject to the ownership limitations specified in Section 4(f) hereof) using the record date for determining the stockholders
of the Company eligible to vote on such matters as the date as of which the Conversion Price is calculated. Holders of the Preferred
Shares shall be entitled to written notice of all stockholder meetings or written consents (and copies of proxy materials and other
information sent to stockholders) with respect to which they would be entitled by vote, which notice would be provided pursuant
to the Company’s bylaws and the DGCL).


 


11.           Liquidation,
Dissolution, Winding-Up. In the event of a Liquidation Event, the Holders shall be entitled to receive in cash out of the assets
of the Company, whether from capital or from earnings available for distribution to its stockholders (the “Liquidation
Funds”), before any amount shall be paid to the holders of any of shares of Junior Stock, an amount per Preferred Share
equal to the Stated Value on the date of such payment, provided that if the Liquidation Funds are insufficient to pay the full
amount due to the Holders and holders of shares of Parity Stock, then each Holder and each holder of Parity Stock shall receive
a percentage of the Liquidation Funds equal to the full amount of Liquidation Funds payable to such Holder and such holder of Parity
Stock as a liquidation preference, in accordance with their respective certificate of designations (or equivalent), as a percentage
of the full amount of Liquidation Funds payable to all holders of Preferred Shares and all holders of shares of Parity Stock. To
the extent necessary, the Company shall cause such actions to be taken by each of its Subsidiaries so as to enable, to the maximum
extent permitted by law, the proceeds of a Liquidation Event to be distributed to the Holders in accordance with this Section 11.
All the preferential amounts to be paid to the Holders under this Section 11 shall be paid or set apart for payment before the
payment or setting apart for payment of any amount for, or the distribution of any Liquidation Funds of the Company to the holders
of shares of Junior Stock in connection with a Liquidation Event as to which this Section 11 applies.


 




    	 	12	 



     


    

 


12.           Participation.
In addition to any adjustments pursuant to Section 8, the Holders shall, as holders of Preferred Shares, be entitled to receive
such dividends paid and distributions made to the holders of shares of Common Stock to the same extent as if such Holders had converted
each Preferred Share held by each of them into shares of Common Stock (without regard to any limitations on conversion herein or
elsewhere) and had held such shares of Common Stock on the record date for such dividends and distributions. Payments under the
preceding sentence shall be made concurrently with the dividend or distribution to the holders of shares of Common Stock (provided,
however, to the extent that a Holder’s right to participate in any such dividend or distribution would result in such Holder
exceeding the Maximum Percentage, then such Holder shall not be entitled to participate in such dividend or distribution to such
extent (or the beneficial ownership of any such shares of Common Stock as a result of such dividend or distribution to such extent)
and such dividend or distribution to such extent shall be held in abeyance for the benefit of such Holder until such time, if ever,
as its right thereto would not result in such Holder exceeding the Maximum Percentage).


 


13.           Vote to Change
the Terms of or Issue Preferred Shares. In addition to any other rights provided by law, except where the vote or written consent
of the holders of a greater number of shares is required by law or by another provision of the Certificate of Incorporation, without
first obtaining the affirmative vote at a meeting duly called for such purpose or the written consent without a meeting of the
Required Holders, voting together as a single class, the Company shall not amend or repeal any provision of, or add any provision
to, its Certificate of Incorporation or bylaws, or file any certificate of designations or articles of amendment of any series
of shares of preferred stock, if such action would adversely alter or change in any respect the preferences, rights, privileges
or powers, or restrictions provided for the benefit, of the Preferred Shares, regardless of whether any such action shall be by
means of amendment to the Certificate of Incorporation or by merger, consolidation or otherwise; provided, however, the Company
shall be entitled, without the consent of the Required Holders unless such consent is otherwise required by the DGCL, to (a) amend
the Certificate of Incorporation to effectuate one or more reverse stock splits of its issued and outstanding Common Stock for
purposes of maintaining compliance with the rules and regulations of the Principal Market; (b) purchase, repurchase or redeem any
shares of capital stock of the Company junior in rank to the Preferred Shares (other than pursuant to equity incentive agreements
(that have in good faith been approved by the Board) with employees giving the Company the right to repurchase shares upon the
termination of services); or (c) issue any preferred stock that is junior in rank to the Preferred Shares.


 




    	 	13	 



     


    

 


14.           Lost
or Stolen Certificates. Upon receipt by the Company of evidence reasonably satisfactory to the Company of the loss, theft,
destruction or mutilation of any certificates representing Preferred Shares (as to which a written certification and the indemnification
contemplated below shall suffice as such evidence), and, in the case of loss, theft or destruction, of an indemnification undertaking
by the applicable Holder to the Company in customary and reasonable form and, in the case of mutilation, upon surrender and cancellation
of the certificate(s), the Company shall execute and deliver new certificate(s) of like tenor and date.


 


15.           Remedies,
Characterizations, Other Obligations, Breaches and Injunctive Relief. The remedies provided in this Certificate of Designation
shall be cumulative and in addition to all other remedies available under this Certificate of Designation and any of the other
Transaction Documents, at law or in equity (including a decree of specific performance and/or other injunctive relief), and no
remedy contained herein shall be deemed a waiver of compliance with the provisions giving rise to such remedy. Nothing herein shall
limit any Holder’s right to pursue actual and consequential damages for any failure by the Company to comply with the terms
of this Certificate of Designation. The Company covenants to each Holder that there shall be no characterization concerning this
instrument other than as expressly provided herein. Amounts set forth or provided for herein with respect to payments, conversion
and the like (and the computation thereof) shall be the amounts to be received by a Holder and shall not, except as expressly provided
herein, be subject to any other obligation of the Company (or the performance thereof). The Company acknowledges that a breach
by it of its obligations hereunder will cause irreparable harm to the Holders and that the remedy at law for any such breach may
be inadequate. The Company therefore agrees that, in the event of any such breach or threatened breach, each Holder shall be entitled,
in addition to all other available remedies, to an injunction restraining any such breach or any such threatened breach, without
the necessity of showing economic loss and without any bond or other security being required, to the extent permitted by applicable
law. The Company shall provide all information and documentation to a Holder that is requested by such Holder to enable such Holder
to confirm the Company’s compliance with the terms and conditions of this Certificate of Designation.


 


16.           Noncircumvention.
The Company hereby covenants and agrees that the Company will not, by amendment of its Certificate of Incorporation, bylaws or
through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issue or sale of securities,
or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Certificate of
Designation, and will at all times in good faith carry out all the provisions of this Certificate of Designation and take all action
as may be required to protect the rights of the Holders. Without limiting the generality of the foregoing or any other provision
of this Certificate of Designation, the Company (i) shall not increase the par value of any shares of Common Stock receivable
upon the conversion of any Preferred Shares above the Conversion Price then in effect, (ii) shall take all such actions as
may be necessary or appropriate in order that the Company may validly and legally issue fully paid and non-assessable shares of
Common Stock upon the conversion of Preferred Shares and (iii) shall, so long as any Preferred Shares are outstanding, take all
action necessary to reserve and keep available out of its authorized and unissued shares of Common Stock, solely for the purpose
of effecting the conversion of the Preferred Shares, the maximum number of shares of Common Stock as shall from time to time be
necessary to effect the conversion of the Preferred Shares then outstanding (without regard to any limitations on conversion contained
herein).


 




    	 	14	 



     


    

 


17.           Failure
or Indulgence Not Waiver. No failure or delay on the part of a Holder in the exercise of any power, right or privilege hereunder
shall operate as a waiver thereof, nor shall any single or partial exercise of any such power, right or privilege preclude other
or further exercise thereof or of any other right, power or privilege. No waiver shall be effective unless it is in writing and
signed by an authorized representative of the waiving party. This Certificate of Designation shall be deemed to be jointly drafted
by the Company and all Holders and shall not be construed against any Person as the drafter hereof.


 


18.           Notices.
The Company shall provide each Holder of Preferred Shares with prompt written notice of all actions taken pursuant to the terms
of this Certificate of Designation, including in reasonable detail a description of such action and the reason therefor. Whenever
notice is required to be given under this Certificate of Designation, unless otherwise provided herein, such notice must be in
writing and shall be given in accordance with the signature page of the Securities Purchase Agreement. Without limiting the generality
of the foregoing, the Company shall give written notice to each Holder (i) promptly following any adjustment of the Conversion
Price, setting forth in reasonable detail, and certifying, the calculation of such adjustment and (ii) at least fifteen (15) days
prior to the date on which the Company closes its books or takes a record (A) with respect to any dividend or distribution upon
the Common Stock, (B) with respect to any grant, issuances, or sales of any Options, Convertible Securities or rights to purchase
stock, warrants, securities or other property to all holders of shares of Common Stock as a class or (C) for determining rights
to vote with respect to any Fundamental Transaction, dissolution or liquidation, provided, in each case, that such information
shall be made known to the public prior to, or simultaneously with, such notice being provided to any Holder.


  


19.           Transfer
of Preferred Shares. Subject to the restrictions set forth in the Securities Purchase Agreement, a Holder may transfer some
or all of its Preferred Shares without the consent of the Company.


 


20.           Preferred
Shares Register. The Company shall maintain at its principal executive offices (or such other office or agency of the Company
as it may designate by notice to the Holders), a register for the Preferred Shares, in which the Company shall record the name,
address and facsimile number of the Persons in whose name the Preferred Shares have been issued, as well as the name and address
of each transferee. The Company may treat the Person in whose name any Preferred Shares is registered on the register as the owner
and holder thereof for all purposes, notwithstanding any notice to the contrary, but in all events recognizing any properly made
transfers.


 


21.           Amendment.
This Certificate of Designation or any provision hereof may be amended by obtaining the affirmative vote at a meeting duly called
for such purpose, or written consent without a meeting in accordance with the DGCL, of the Required Holders, voting separate as
a single class, and with such other stockholder approval, if any, as may then be required pursuant to the DGCL and the Certificate
of Incorporation.

Company or the applicable Holder (as the case may be) shall submit the dispute to the other party via facsimile (A) if by the Company,
within two (2) Business Days after the occurrence of the circumstances giving rise to such dispute or (B) if by such Holder at
any time after such Holder learned of the circumstances giving rise to such dispute. If such Holder and the Company are unable
to promptly resolve such dispute relating to such Closing Sale Price, such Conversion Price, such VWAP or such fair market value,
or the arithmetic calculation of such Conversion Rate (as the case may be), at any time after the second (2nd) Business
Day following such initial notice by the Company or such Holder (as the case may be) of such dispute to the Company or such Holder
(as the case may be), then such Holder may, at its sole option, select an independent, reputable investment bank to resolve such
dispute.


 


(ii) Such Holder
and the Company shall each deliver to such investment bank (A) a copy of the initial dispute submission so delivered in accordance
with the first sentence of this Section 22 and (B) written documentation supporting its position with respect to such dispute,
in each case, no later than 5:00 p.m. (New York time) by the fifth (5th) Business Day immediately following the date
on which such Holder selected such investment bank (the “Dispute Submission Deadline”) (the documents referred
to in the immediately preceding clauses (A) and (B) are collectively referred to herein as the “Required Dispute Documentation”)
(it being understood and agreed that if either such Holder or the Company fails to so deliver all of the Required Dispute Documentation
by the Dispute Submission Deadline, then the party who fails to so submit all of the Required Dispute Documentation shall no longer
be entitled to (and hereby waives its right to) deliver or submit any written documentation or other support to such investment
bank with respect to such dispute and such investment bank shall resolve such dispute based solely on the Required Dispute Documentation
that was delivered to such investment bank prior to the Dispute Submission Deadline). Unless otherwise agreed to in writing by
both the Company and such Holder or otherwise requested by such investment bank, neither the Company nor such Holder shall be entitled
to deliver or submit any written documentation or other support to such investment bank in connection with such dispute (other
than the Required Dispute Documentation) .

(iii) The Company
and such Holder shall cause such investment bank to determine the resolution of such dispute and notify the Company and such Holder
of such resolution no later than ten (10) Business Days immediately following the Dispute Submission Deadline. The fees and expenses
of such investment bank shall be borne solely by the Company, and such investment bank’s resolution of such dispute shall
be final and binding upon all parties absent manifest error.


 


(b)          Miscellaneous.


 


(i)          The
Company expressly acknowledges and agrees that (i) this Section 22 constitutes an agreement to arbitrate between the Company and
each Holder (and constitutes an arbitration agreement) under §7501, et seq. of the New York Civil Practice Law and Rules (“CPLR”)
and that any Holder is authorized to apply for an order to compel arbitration pursuant to CPLR §7503(a) in order to compel
compliance with this Section 22, (ii) the terms of this Certificate of Designation and each other applicable Transaction Document
shall serve as the basis for the selected investment bank’s resolution of the applicable dispute, such investment bank shall
be entitled (and is hereby expressly authorized) to make all findings, determinations and the like that such investment bank determines
are required to be made by such investment bank in connection with its resolution of such dispute and in resolving such dispute
such investment bank shall apply such findings, determinations and the like to the terms of this Certificate of Designation and
any other applicable Transaction Document, (iii) the applicable Holder (and only such Holder with respect to disputes solely relating
to such Holder), in its sole discretion, shall have the right to submit any dispute described in this Section 22 to any state or
federal court sitting in the City of New York, Borough of Manhattan, subject to any choice of law provision in the Securities Purchase
Agreement, in lieu of utilizing the procedures set forth in this Section 22 and (iv) nothing in this Section 22 shall limit such
Holder from obtaining any injunctive relief or other equitable remedies (including, without limitation, with respect to any matters
described in this Section 22).


 


(ii)         Whenever
any payment of cash is to be made by the Company to any Person pursuant to this Certificate of Designation, unless otherwise expressly
set forth herein, such payment shall be made in lawful money of the United States of America by a certified check drawn on the
account of the Company and sent via overnight courier service to such Person at such address as previously provided to the Company
in writing, provided that such Holder may elect to receive a payment of cash via wire transfer of immediately available funds by
providing the Company with prior written notice setting out such request and such Holder’s wire transfer instructions. Whenever
any amount expressed to be due by the terms of this Certificate of Designation is due on any day which is not a Business Day, the
same shall instead be due on the next succeeding day which is a Business Day. Any amount due hereunder which is not paid when due
shall result in a late charge being incurred and payable by the Company in an amount equal to interest on such amount at the rate
of nine percent (9%) per year from the date such amount was due until the same is paid in full (“Late Charge”).
