Stock by the Conversion Price. Holders shall effect conversions by providing the Corporation with the form of conversion notice
attached hereto as Annex A (a “Notice of Conversion”). Each Notice of Conversion shall specify the number
of shares of Preferred Stock to be converted, the number of shares of Preferred Stock owned prior to the conversion at issue, the
number of shares of Preferred Stock owned subsequent to the conversion at issue and the date on which such conversion is to be
effected, which date may not be prior to the date the applicable Holder delivers by facsimile such Notice of Conversion to the

Notice of Conversion shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice
of Conversion form be required. The calculations and entries set forth in the Notice of Conversion shall control in the

Stock represented thereby are so converted, in which case such Holder shall deliver the certificate representing such shares of
Preferred Stock promptly following the Conversion Date at issue. Shares of Preferred Stock converted into Common Stock or redeemed
in accordance with the terms hereof shall be canceled and shall not be reissued.


 






    	7



    	 



    

 


b)                 
Conversion Price. The conversion price for the Preferred Stock shall equal $1.00, subject to adjustment herein

c)                 
Mechanics of Conversion



 


                                                                
i.                             
Delivery of Conversion Shares Upon Conversion. Not later than three (3) Trading Days after each Conversion Date (the
“Share Delivery Date”), the Corporation shall deliver, or cause to be delivered, to the converting Holder the
number of Conversion Shares being acquired upon the conversion of the Preferred Stock, which, on or after the earlier of (i) the
six month anniversary of the Original Issue Date or (ii) the Effective Date, shall be free of restrictive legends and trading restrictions.
On or after the earlier of (i) the six month anniversary of the Original Issue Date or (ii) the Effective Date, the Corporation
shall deliver the Conversion Shares required to be delivered by the Corporation under this Section 6 electronically through the
Depository Trust Company or another established clearing corporation performing similar functions.


 


                                                                 
ii.                       
Failure to Deliver Conversion Shares. If, in the case of any Notice of Conversion, such Conversion Shares are not
delivered to or as directed by the applicable Holder by the Share Delivery Date, the Holder shall be entitled to elect by written
notice to the Corporation at any time on or before its receipt of such Conversion Shares, to rescind such Conversion, in which
event the Corporation shall promptly return to the Holder any original Preferred Stock certificate delivered to the Corporation
and the Holder shall promptly return to the Corporation the Conversion Shares issued to such Holder pursuant to the rescinded Conversion
Notice.


 


                                                               
iii.                       
Obligation Absolute; Partial Liquidated Damages. The Corporation’s obligation to issue and deliver the Conversion
Shares upon conversion of Preferred Stock in accordance with the terms hereof are absolute and unconditional, irrespective of any
action or inaction by a Holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of
any judgment against any Person or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination,
or any breach or alleged breach by such Holder or any other Person of any obligation to the Corporation or any violation or alleged
violation of law by such Holder or any other person, and irrespective of any other circumstance which might otherwise limit such
obligation of the Corporation to such Holder in connection with the issuance of such Conversion Shares; provided, however,
that such delivery shall not operate as a waiver by the Corporation of any such action that the Corporation may have against such
Holder. In the event a Holder shall elect to convert any or all of the Stated Value of its Preferred Stock, the Corporation may
not refuse conversion based on any claim that such Holder or any one associated or affiliated with such Holder has been engaged
in any violation of law, agreement or for any other reason, unless an injunction from a court, on notice to Holder, restraining
and/or enjoining conversion of all or part of the Preferred Stock of such Holder shall have been sought and obtained, and the Corporation
posts a surety bond for the benefit of such Holder in the amount of 150% of the Stated Value of Preferred Stock which is subject
to the injunction, which bond shall remain in effect until the completion of arbitration/litigation of the underlying dispute and
the proceeds of which shall be payable to such Holder to the extent it obtains judgment. In the absence of such injunction, the
Corporation shall issue Conversion Shares and, if applicable, cash, upon a properly noticed conversion. If the Corporation fails
to deliver to a Holder such Conversion Shares pursuant to Section 6(c)(i) on the second Trading Day after the Share Delivery Date
applicable to such conversion, the Corporation shall pay to such Holder, in cash, as liquidated damages and not as a penalty, for
each $5,000 of Stated Value of Preferred Stock being converted, $50 per Trading Day (increasing to $100 per Trading Day on the
third Trading Day and increasing to $200 per Trading Day on the sixth Trading Day after such damages begin to accrue) for each
Trading Day after such second Trading Day after the Share Delivery Date until such Conversion Shares are delivered or Holder rescinds
such conversion. Nothing herein shall limit a Holder’s right to pursue actual damages or declare a Triggering Event pursuant
to Section 10 hereof for the Corporation’s failure to deliver Conversion Shares within the period specified herein and such
Holder shall have the right to pursue all remedies available to it hereunder, at law or in equity including, without limitation,
a decree of specific performance and/or injunctive relief. The exercise of any such rights shall not prohibit a Holder from seeking
to enforce damages pursuant to any other Section hereof or under applicable law.

iv.                       
Compensation for Buy-In on Failure to Timely Deliver Conversion Shares Upon Conversion. In addition to any other
rights available to the Holder, if the Corporation fails for any reason to deliver to a Holder the applicable Conversion Shares
by the Share Delivery Date pursuant to Section 6(c)(i), and if after such Share Delivery Date such Holder is required by its brokerage
firm to purchase (in an open market transaction or otherwise), or the Holder’s brokerage firm otherwise purchases, shares
of Common Stock to deliver in satisfaction of a sale by such Holder of the Conversion Shares which such Holder was entitled to
receive upon the conversion relating to such Share Delivery Date (a “Buy-In”), then the Corporation shall (A)
pay in cash to such Holder (in addition to any other remedies available to or elected by such Holder) the amount, if any, by which
(x) such Holder’s total purchase price (including any brokerage commissions) for the Common Stock so purchased exceeds (y)
the product of (1) the aggregate number of shares of Common Stock that such Holder was entitled to receive from the conversion
at issue multiplied by (2) the actual sale price at which the sell order giving rise to such purchase obligation was executed (including
any brokerage commissions) and (B) at the option of such Holder, either reissue (if surrendered) the shares of Preferred Stock
equal to the number of shares of Preferred Stock submitted for conversion (in which case, such conversion shall be deemed rescinded)
or deliver to such Holder the number of shares of Common Stock that would have been issued if the Corporation had timely complied
with its delivery requirements under Section 6(c)(i). For example, if a Holder purchases shares of Common Stock having a total
purchase price of $11,000 to cover a Buy-In with respect to an attempted conversion of shares of Preferred Stock with respect to
which the actual sale price of the Conversion Shares (including any brokerage commissions) giving rise to such purchase obligation
was a total of $10,000 under clause (A) of the immediately preceding sentence, the Corporation shall be required to pay such Holder
$1,000. The Holder shall provide the Corporation written notice indicating the amounts payable to such Holder in respect of the
Buy-In and, upon request of the Corporation, evidence of the amount of such loss. Nothing herein shall limit a Holder’s right
to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific
performance and/or injunctive relief with respect to the Corporation’s failure to timely deliver the Conversion Shares upon
conversion of the shares of Preferred Stock as required pursuant to the terms hereof.

v.                       
Reservation of Shares Issuable Upon Conversion. The Corporation covenants that it will at all times reserve and keep
available out of its authorized and unissued shares of Common Stock for the sole purpose of issuance upon conversion of the Preferred
Stock, free from preemptive rights or any other actual contingent purchase rights of Persons other than the Holder (and the other
holders of the Preferred Stock), not less than such aggregate number of shares of the Common Stock as shall (subject to the terms
and conditions set forth in the Purchase Agreement) be issuable (taking into account the adjustments and restrictions of Section
7) upon the conversion of the then outstanding shares of Preferred Stock. The Corporation covenants that all shares of Common Stock
that shall be so issuable shall, upon issue, be duly authorized, validly issued, fully paid and nonassessable and, if the Conversion
Shares Registration Statement is then effective under the Securities Act, shall be registered for public resale in accordance with
such Conversion Shares Registration Statement (subject to such Holder’s compliance with its obligations under the Registration
Rights Agreement).


 


                                                               
vi.                       
Fractional Shares. No fractional shares or scrip representing fractional shares shall be issued upon the conversion
of the Preferred Stock. As to any fraction of a share which the Holder would otherwise be entitled to purchase upon such conversion,
the Corporation shall at its election, either pay a cash adjustment in respect of such final fraction in an amount equal to such
fraction multiplied by the Conversion Price or round up to the next whole share.


 


                                                             
vii.                       
Transfer Taxes and Expenses. The issuance of Conversion Shares on conversion of this Preferred Stock shall be made
without charge to any Holder for any documentary stamp or similar taxes that may be payable in respect of the issue or delivery
of such Conversion Shares, provided that the Corporation shall not be required to pay any tax that may be payable in respect of
any transfer involved in the issuance and delivery of any such Conversion Shares upon conversion in a name other than that of the
Holders of such shares of Preferred Stock and the Corporation shall not be required to issue or deliver such Conversion Shares
unless or until the Person or Persons requesting the issuance thereof shall have paid to the Corporation the amount of such tax
or shall have established to the satisfaction of the Corporation that such tax has been paid. The Corporation shall pay all Transfer
Agent fees required for same-day processing of any Notice of Conversion and all fees to the Depository Trust Company (or another
established clearing corporation performing similar functions) required for same-day electronic delivery of the Conversion Shares.

d)                
Beneficial Ownership Limitation. The Corporation shall not effect any conversion of the Preferred Stock,
and a Holder shall not have the right to convert any portion of the Preferred Stock, to the extent that, after giving effect to
the conversion set forth on the applicable Notice of Conversion, such Holder (together with such Holder’s Affiliates, and
any Persons acting as a group together with such Holder or any of such Holder’s Affiliates) would beneficially own in excess
of the Beneficial Ownership Limitation (as defined below).  For purposes of the foregoing sentence, the number of shares
of Common Stock beneficially owned by such Holder and its Affiliates shall include the number of shares of Common Stock issuable
upon conversion of the Preferred Stock with respect to which such determination is being made, but shall exclude the number of
shares of Common Stock which are issuable upon (i) conversion of the remaining, unconverted Stated Value of Preferred Stock beneficially
owned by such Holder or any of its Affiliates and (ii) exercise or conversion of the unexercised or unconverted portion of any
other securities of the Corporation subject to a limitation on conversion or exercise analogous to the limitation contained herein
(including, without limitation, the Preferred Stock or the Warrants) beneficially owned by such Holder or any of its Affiliates. 
Except as set forth in the preceding sentence, for purposes of this Section 6(d), beneficial ownership shall be calculated in
accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. To the extent that the
limitation contained in this Section 6(d) applies, the determination of whether the Preferred Stock is convertible (in relation
to other securities owned by such Holder together with any Affiliates) and of how many shares of Preferred Stock are convertible
shall be in the sole discretion of such Holder, and the submission of a Notice of Conversion shall be deemed to be such Holder’s
determination of whether the shares of Preferred Stock may be converted (in relation to other securities owned by such Holder
together with any Affiliates) and how many shares of the Preferred Stock are convertible, in each case subject to the Beneficial
Ownership Limitation. To ensure compliance with this restriction, each Holder will be deemed to represent to the Corporation each
time it delivers a Notice of Conversion that such Notice of Conversion has not violated the restrictions set forth in this paragraph
and the Corporation shall have no obligation to verify or confirm the accuracy of such determination. In
addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d) of
the Exchange Act and the rules and regulations promulgated thereunder.
For purposes of this Section 6(d), in determining the number of outstanding shares of Common Stock, a Holder may rely
on the number of outstanding shares of Common Stock as stated in the most recent of the following: (i) the Corporation’s
most recent periodic or annual report filed with the Commission, as the case may be, (ii) a more recent public announcement by
the Corporation or (iii) a more recent written notice by the Corporation or the Transfer Agent setting forth the number of shares
of Common Stock outstanding.  Upon the written or oral request of a Holder, the Corporation shall within two Trading Days
confirm orally and in writing to such Holder the number of shares of Common Stock then outstanding.  In any case, the number
of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the
Corporation, including the Preferred Stock, by such Holder or its Affiliates since the date as of which such number of outstanding
shares of Common Stock was reported. The “Beneficial Ownership Limitation” shall be 9.99% of the number of
shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock issuable upon
conversion of Preferred Stock held by the applicable Holder. A Holder, upon not less than 61 days’ prior notice to the Corporation,
may increase or decrease the Beneficial Ownership Limitation provisions of this Section 6(d) applicable to its Preferred Stock
provided that the Beneficial Ownership Limitation in no event exceeds 9.99% of the number of shares of the Common Stock outstanding
immediately after giving effect to the issuance of shares of Common Stock upon conversion of this Preferred Stock held by the
Holder and the provisions of this Section 6(d) shall continue to apply. Any such increase or decrease will not be effective until
the 61st day after such notice is delivered to the Corporation and shall only apply to such Holder and no other Holder.
The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms
of this Section 6(d) to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended
Beneficial Ownership Limitation contained herein or to make changes or supplements necessary or desirable to properly give effect
to such limitation. The limitations contained in this paragraph shall apply to a successor
holder of Preferred Stock.

e)                 
Issuance Limitations. Notwithstanding anything herein to the contrary, if the Corporation has not obtained
Shareholder Approval, then the Corporation may not issue, upon conversion of the Preferred Stock, a number of shares of Common
Stock which, when aggregated with any shares of Common Stock issued on or after the Original Issue Date and prior to such Conversion
Date (i) in connection with any conversion of Preferred Stock issued pursuant to the Purchase Agreement, (ii) with any conversion
of Series D-1 Preferred Stock issued pursuant to the Purchase Agreement, (iii) in connection with the Shares issued pursuant to
the Purchase Agreement, and (iv) in connection with the exercise of any warrants issued to any registered broker-dealer as a fee
in connection with the issuance of the Securities pursuant to the Purchase Agreement, would exceed 6,712,993 shares of Common Stock
(subject to adjustment for forward and reverse stock splits, recapitalizations and the like) (such number of shares, the “Issuable
Maximum”). Each Holder shall be entitled to a portion of the Issuable Maximum equal to the quotient obtained by dividing
(x) the original Stated Value of such Holder’s Preferred Stock by (y) the aggregate Stated Value of all Preferred Stock issued
on the Original Issue Date to all Holders. In addition, each Holder may allocate its pro-rata portion of the Issuable Maximum among
Preferred Stock and Series D-1 Preferred Stock held by it in its sole discretion. Such portion shall be adjusted upward ratably
in the event a Holder no longer holds any Preferred Stock or Series D-1 Preferred Stock and the amount of shares issued to such
Holder pursuant to such Holder’s Preferred Stock and Series D-1 Preferred Stock was less than such Holder’s pro-rata
share of the Issuable Maximum. For avoidance of doubt, unless and until any required Shareholder Approval is obtained and effective,
warrants issued to any registered broker-dealer as a fee in connection with the Securities issued pursuant to the Purchase Agreement
as described in clause (iii) above shall provide that such warrants shall not be allocated any portion of the Issuable Maximum
and shall be unexercisable unless and until such Shareholder Approval is obtained and effective.


 


Section 7. Certain
Adjustments.


 


a)                 
Stock Dividends and Stock Splits. If the Corporation, at any time while this Preferred Stock is outstanding: (i)
pays a stock dividend or otherwise makes a distribution or distributions payable in shares of Common Stock on shares of Common
Stock or any other Common Stock Equivalents (which, for avoidance of doubt, shall not include any shares of Common Stock issued
by the Corporation upon conversion of, or payment of a dividend on, this Preferred Stock), (ii) subdivides outstanding shares of
Common Stock into a larger number of shares, (iii) combines (including by way of a reverse stock split) outstanding shares of Common
Stock into a smaller number of shares, or (iv) issues, in the event of a reclassification of shares of the Common Stock, any shares
of capital stock of the Corporation, then the Conversion Price shall be multiplied by a fraction of which the numerator shall be
the number of shares of Common Stock (excluding any treasury shares of the Corporation) outstanding immediately before such event,
and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event. Any adjustment
made pursuant to this Section 7(a) shall become effective immediately after the record date for the determination of stockholders
entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of
a subdivision, combination or re-classification.


 






    	12



    	 



    

 


b)                 
Subsequent Equity Sales. From the date hereof until such date immediately following the 20 consecutive Trading Days
wherein (i) the VWAP for each Trading Day during such 20 consecutive Trading Day period exceeds $1.50 (subject
to adjustment for forward and reverse stock splits and the like) and (iii) there is an effective registration statement
(including the Registration Statement) of the Corporation that permits the Holder to resell all of the Conversion Shares thereunder,
if, at any time while this Preferred Stock is outstanding, the Corporation or any Subsidiary, as applicable sells or grants any
option to purchase or sells or grants any right to reprice, or otherwise disposes of or issues (or announces any sale, grant or
any option to purchase or other disposition), any Common Stock or Common Stock Equivalents entitling any Person to acquire shares
of Common Stock at an effective price per share that is lower than the then Conversion Price (such lower price, 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 7(b) in respect of an Exempt Issuance. If the Corporation enters into a Variable Rate Transaction, despite the prohibition
set forth in the Purchase Agreement, the Corporation shall be deemed to have issued Common Stock or Common Stock Equivalents at
the lowest possible conversion price at which such securities may be converted or exercised. The Corporation 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 7(b), indicating therein the applicable issuance price, or applicable reset price, exchange price, conversion price and
other pricing terms (such notice, the “Dilutive Issuance Notice”). For purposes of clarification, whether or
not the Corporation provides a Dilutive Issuance Notice pursuant to this Section 7(b), upon the occurrence of any Dilutive Issuance,
the Holders are 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 a Holder accurately refers to the Base Conversion Price in the Notice of Conversion.


 


c)                 
Subsequent Rights Offerings. In addition to any adjustments pursuant to Section 7(a) above, if at any time the Corporation
grants, issues or sells any Common Stock Equivalents or rights to purchase stock, warrants, securities or other property pro rata
to the record holders of any class of shares of Common Stock (the “Purchase Rights”), then the Holder will be
entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have
acquired if the Holder had held the number of shares of Common Stock acquirable upon complete conversion of such Holder’s
Preferred Stock (without regard to any limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation)
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 shares of Common Stock are to be determined for the grant, issue or
sale of such Purchase Rights (provided, however, to the extent that the Holder’s right to participate in any such Purchase
Right would result in the Holder exceeding the Beneficial Ownership Limitation, then the 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 the Holder until such time, if ever, as its
right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation).


 






    	13



    	 



    

 


d)                
Pro Rata Distributions. Subject to Section 3, during such time as this Preferred Stock is outstanding, if the Corporation
declares or makes any dividend or other distribution of its assets (or rights to acquire its assets) to holders of shares of Common
Stock, by way of return of capital or otherwise (including, without limitation, any distribution of cash, stock or other securities,
property or options by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar
transaction) (a "Distribution"), at any time after the issuance of this Preferred Stock, then, in each such case,
the Holder shall be entitled to participate in such Distribution to the same extent that the Holder would have participated therein
if the Holder had held the number of shares of Common Stock acquirable upon complete Conversion of this Preferred Stock (without
regard to any limitations on Conversion hereof, including without limitation, the Beneficial Ownership Limitation) immediately
before the date of which a record is taken for such Distribution, or, if no such record is taken, the date as of which the record
holders of shares of Common Stock are to be determined for the participation in such Distribution (provided, however,
to the extent that the Holder's right to participate in any such Distribution would result in the Holder exceeding the Beneficial
Ownership Limitation, then the Holder shall not be entitled to participate in such Distribution to such extent (or in the beneficial
ownership of any shares of Common Stock as a result of such Distribution to such extent) and the portion of such Distribution shall
be held in abeyance for the benefit of the Holder until such time, if ever, as its right thereto would not result in the Holder
exceeding the Beneficial Ownership Limitation).


 


e)                 
Fundamental Transaction. If, at any time while this Preferred Stock is outstanding, (i) the Corporation, directly
or indirectly, in one or more related transactions effects any merger or consolidation of the Corporation with or into another
Person, (ii) the Corporation, directly or indirectly, effects any sale, lease, license, assignment, transfer, conveyance or other
disposition of all or substantially all of its assets in one or a series of related transactions, (iii) any, direct or indirect,
purchase offer, tender offer or exchange offer (whether by the Corporation or another Person) is completed pursuant to which holders
of Common Stock are permitted to sell, tender or exchange their shares for other securities, cash or property and has been accepted
by the holders of 50% or more of the outstanding Common Stock, (iv) the Corporation, directly or indirectly, in one or more related
transactions effects any reclassification, reorganization or recapitalization of the Common Stock or any compulsory share exchange
pursuant to which the Common Stock is effectively converted into or exchanged for other securities, cash or property, or (v) the
Corporation, directly or indirectly, in one or more related transactions consummates a stock or share purchase agreement or other
business combination (including, without limitation, a reorganization, recapitalization, spin-off or scheme of arrangement) with
another Person whereby such other Person acquires more than 50% of the outstanding shares of Common Stock (not including any shares
of Common Stock held by the other Person or other Persons making or party to, or associated or affiliated with the other Persons
making or party to, such stock or share purchase agreement or other business combination) (each a “Fundamental Transaction”),
then, upon any subsequent conversion of this Preferred Stock, the Holder shall have the right to receive, for each Conversion Share
that would have been issuable upon such conversion immediately prior to the occurrence of such Fundamental Transaction (without
regard to any limitation in Section 6(d) and Section 6(e) on the conversion of this Preferred Stock), the number of shares of Common
Stock of the successor or acquiring corporation or of the Corporation, if it is the surviving corporation, and any additional consideration
(the “Alternate Consideration”) receivable as a result of such Fundamental Transaction by a holder of the number
of shares of Common Stock for which this Preferred Stock is convertible immediately prior to such Fundamental Transaction (without
regard to any limitation in Section 6(d) and Section 6(e) on the conversion of this Preferred Stock). For purposes of any such
conversion, the determination of the Conversion Price shall be appropriately adjusted to apply to such Alternate Consideration
based on the amount of Alternate Consideration issuable in respect of one share of Common Stock in such Fundamental Transaction,
and the Corporation shall apportion the Conversion Price among the Alternate Consideration in a reasonable manner reflecting the
relative value of any different components of the Alternate Consideration. If holders of Common Stock are given any choice as to
the securities, cash or property to be received in a Fundamental Transaction, then the Holder shall be given the same choice as
to the Alternate Consideration it receives upon any conversion of this Preferred Stock following such Fundamental Transaction.
To the extent necessary to effectuate the foregoing provisions, any successor to the Corporation or surviving entity in such Fundamental
Transaction shall file a new Certificate of Designation with the same terms and conditions and issue to the Holders new preferred
stock consistent with the foregoing provisions and evidencing the Holders’ right to convert such preferred stock into Alternate
Consideration. The Corporation shall cause any successor entity in a Fundamental Transaction in which the Corporation is not the
survivor (the “Successor Entity”) to assume in writing all of the obligations of the Corporation under this
Certificate of Designation and the other Transaction Documents (as defined in the Purchase Agreement) in accordance with the provisions
of this Section 7(e) pursuant to written agreements in form and substance reasonably satisfactory to the Holder and approved by
the Holder (without unreasonable delay) prior to such Fundamental Transaction and shall, at the option of the holder of this Preferred
Stock, deliver to the Holder in exchange for this Preferred Stock a security of the Successor Entity evidenced by a written instrument
substantially similar in form and substance to this Preferred Stock which is convertible for a corresponding number of shares of
capital stock of such Successor Entity (or its parent entity) equivalent to the shares of Common Stock acquirable and receivable
upon conversion of this Preferred Stock (without regard to any limitations on the conversion of this Preferred Stock) prior to
such Fundamental Transaction, and with a conversion price which applies the conversion price hereunder to such shares of capital
stock (but taking into account the relative value of the shares of Common Stock pursuant to such Fundamental Transaction and the
value of such shares of capital stock, such number of shares of capital stock and such conversion price being for the purpose of
protecting the economic value of this Preferred Stock immediately prior to the consummation of such Fundamental Transaction), and
which is reasonably satisfactory in form and substance to the Holder. Upon the occurrence of any such Fundamental Transaction,
the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction,
the provisions of this Certificate of Designation and the other Transaction Documents referring to the “Corporation”
shall refer instead to the Successor Entity), and may exercise every right and power of the Corporation and shall assume all of
the obligations of the Corporation under this Certificate of Designation and the other Transaction Documents with the same effect
as if such Successor Entity had been named as the Corporation herein.

f)                  
Calculations. All calculations under this Section 7 shall be made to the nearest cent or the nearest 1/100th of a
share, as the case may be. For purposes of this Section 7, the number of shares of Common Stock deemed to be issued and outstanding
as of a given date shall be the sum of the number of shares of Common Stock (excluding any treasury shares of the Corporation)
issued and outstanding.


 


g)                 
Notice to the Holders.


 


                                                                   
i.                       
Adjustment to Conversion Price. Whenever the Conversion Price is adjusted pursuant to any provision of this Section
7, the Corporation shall promptly deliver to each Holder a notice setting forth the Conversion Price after such adjustment and
setting forth a brief statement of the facts requiring such adjustment.


 


                                                                 
ii.                       
Notice to Allow Conversion by Holder. If (A) the Corporation shall declare a dividend (or any other distribution
in whatever form) on the Common Stock, (B) the Corporation shall declare a special nonrecurring cash dividend on or a redemption
of the Common Stock, (C) the Corporation shall authorize the granting to all holders of the Common Stock of rights or warrants
to subscribe for or purchase any shares of capital stock of any class or of any rights, (D) the approval of any stockholders of
the Corporation shall be required in connection with any reclassification of the Common Stock, any consolidation or merger to which
the Corporation is a party, any sale or transfer of all or substantially all of the assets of the Corporation, or any compulsory
share exchange whereby the Common Stock is converted into other securities, cash or property or (E) the Corporation shall authorize
the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Corporation, then, in each case, the
Corporation shall cause to be filed at each office or agency maintained for the purpose of conversion of this Preferred Stock,
and shall cause to be delivered to each Holder at its last address as it shall appear upon the stock books of the Corporation,
at least twenty (20) calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x)
the date on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if
a record is not to be taken, the date as of which the holders of the Common Stock of record to be entitled to such dividend, distributions,
redemption, rights or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger, sale,
transfer or share exchange is expected to become effective or close, and the date as of which it is expected that holders of the
Common Stock of record shall be entitled to exchange their shares of the Common Stock for securities, cash or other property deliverable
upon such reclassification, consolidation, merger, sale, transfer or share exchange, provided that the failure to deliver such
notice or any defect therein or in the delivery thereof shall not affect the validity of the corporate action required to be specified
in such notice. To the extent that any notice provided hereunder constitutes, or contains, material, non-public information regarding
the Corporation or any of the Subsidiaries, the Corporation shall simultaneously file such notice with the Commission pursuant
to a Current Report on Form 8-K. The Holder shall remain entitled to convert the Conversion Amount of this Preferred Stock (or
any part hereof) during the 20-day period commencing on the date of such notice through the effective date of the event triggering
such notice except as may otherwise be expressly set forth herein.
