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

be the date that such Notice of Conversion to the Corporation is deemed delivered hereunder. The calculations and entries set forth
in the Notice of Conversion shall control in the absence of manifest or mathematical error. No ink-original 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. To effect conversions of shares of Preferred Stock, a Holder shall not be required to surrender the certificate(s)
representing the shares of Preferred Stock to the Corporation unless all of the shares of Preferred 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.

 

b)           Conversion
Price. The conversion price for the Preferred Stock shall equal $0.70, subject to adjustment herein (the “Conversion
Price”).

 

		c)	Mechanics of Conversion

 

i.           Delivery
of Certificate 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 (A) a certificate or certificates
representing the Conversion Shares 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 (other than those which may then be required
by the Purchase Agreement) representing the number of Conversion Shares being acquired upon the conversion of the Preferred Stock
(including, if the Corporation has given continuous notice pursuant to Section 3(b) for payment of dividends in shares of Common
Stock at least 20 Trading Days prior to the date on which the Notice of Conversion is delivered to the Corporation, shares of Common
Stock representing the payment of accrued dividends otherwise determined pursuant to Section 3(a) but assuming that the Dividend
Notice Period is the 20 Trading Days period immediately prior to the date on which the Notice of Conversion is delivered to the
Corporation and excluding for such issuance the condition that the Corporation deliver the Dividend Share Amount as to such dividend
payment prior to the commencement of the Dividend Notice Period), and (B) a bank check in the amount of accrued and unpaid dividends
(if the Corporation has elected or is required to pay accrued dividends in cash). On or after the earlier of (i) the six month
anniversary of the Original Issue Date or (ii) the Effective Date, the Corporation shall use its best efforts to deliver any certificate
or certificates 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 Certificates. If, in the case of any Notice of Conversion, such certificate or certificates 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 certificate or certificates, 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 Common Stock certificates 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 certificate or certificates 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 certificates 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 Certificates 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 certificate or certificates 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 certificates representing shares of
Common Stock upon conversion of the shares of Preferred Stock as required pursuant to the terms hereof.

 

    	 	 

     

    

 

v.          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 in connection with
any conversion of Preferred Stock issued pursuant to the Purchase Agreement, that would exceed 1,193,058 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 Warrants 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 Warrants and the amount of shares issued to such Holder pursuant to such Holder’s
Preferred Stock and Warrants was less than such Holder’s pro-rata share of the Issuable Maximum.

 

vi.         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 and payment
of dividends on the Preferred Stock, each as herein provided, 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
and payment of dividends hereunder. 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).

 

vii.        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.

 

    	 	 

     

    

 

viii.       Transfer
Taxes and Expenses. The issuance of certificates for shares of the Common Stock 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 certificates, 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 certificate 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 certificates 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.

 

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 (such Persons, “Attribution Parties”)) 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 and Attribution Parties 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 or Attribution Parties 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 or Attribution Parties.  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 Attribution Parties) 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 Attribution Parties) 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 or Attribution Parties since the
date as of which such number of outstanding shares of Common Stock was reported. The “Beneficial Ownership Limitation”
shall be 4.99% 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 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 in the Beneficial Ownership Limitation 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.

 

    	 	 

     

    

 

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.

 

    	 	 

     

    

 

b)           RESERVED.

 

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 of 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).

 

d)           Pro
Rata Distributions. 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 by facsimile or e-mail 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
by facsimile or email to each Holder at its last facsimile number or email 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.

subscribe for or acquire any shares of Common Stock, or contracts, commitments, understandings or arrangements by which the Company
or any Subsidiary is or may become bound to issue additional shares of Common Stock or Common Stock Equivalents. The issuance and

the Purchasers) and will not result in a right of any holder of Company securities to adjust the exercise, conversion, exchange
or reset price under any of such securities. All of the outstanding shares of capital stock of the Company are duly authorized,

the Company’s capital stock to which the Company is a party or, to the knowledge of the Company, between or among any of

in favor of any third party, and the continued employment of each such executive officer does not subject the Company or any of
its Subsidiaries to any liability with respect to any of the foregoing matters. The Company and its Subsidiaries are in compliance
with all applicable U.S. federal, state, local and foreign laws and regulations relating to employment and employment practices,
terms and conditions of employment and wages and hours, except where the failure to be in compliance could not, individually or

any notice of proceedings relating to the revocation or modification of any Material Permit.

 

(n)         Title

None of, and neither the Company nor any Subsidiary has received a notice (written or otherwise) that any of, the Intellectual
Property Rights has expired, terminated or been abandoned, or is expected to expire or terminate or be abandoned, within two (2)
years from the date of this Agreement. Neither the Company nor any Subsidiary has received, since the date of the latest audited

no existing infringement by another Person of any of the Intellectual Property Rights. The Company and its Subsidiaries have taken
reasonable security measures to protect the secrecy, confidentiality and value of all of their intellectual properties, except

confirms that neither it nor any other Person acting on its behalf has provided any of the Purchasers or their agents or counsel
with any information that it believes constitutes or might constitute material, non-public information. The Company understands
and confirms that the Purchasers will rely on the foregoing representation in effecting transactions in securities of the Company.
All of the disclosure furnished by or on behalf of the Company to the Purchasers regarding the Company and its Subsidiaries, their
respective businesses and the transactions contemplated hereby, including the Disclosure Schedules to this Agreement, is true and
correct and does not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make

Based on the consolidated financial condition of the Company as of the applicable Closing Date, assuming and giving effect to the
receipt by the Company of the proceeds from the sale of all of the Securities hereunder: (i) the fair saleable value of the Company’s
assets exceeds the amount that will be required to be paid on or in respect of the Company’s existing debts and other liabilities
(including known contingent liabilities) as they mature, (ii) the Company’s assets do not constitute unreasonably small capital
to carry on its business as now conducted and as proposed to be conducted including its capital needs taking into account the particular
capital requirements of the business conducted by the Company, consolidated and projected capital requirements and capital availability
thereof, and (iii) the current cash flow of the Company, together with the proceeds the Company would receive, were it to liquidate
all of its assets, after taking into account all anticipated uses of the cash, would be sufficient to pay all amounts on or in
respect of its liabilities when such amounts are required to be paid. The Company does not intend to incur debts beyond its ability
to pay such debts as they mature (taking into account the timing and amounts of cash to be payable on or in respect of its debt).
The Company has no knowledge of any facts or circumstances which lead it to believe that it will file for reorganization or liquidation
under the bankruptcy or reorganization laws of any jurisdiction within one year from the applicable Closing Date.

of the date hereof and as of the applicable Closing Date to the Company as follows (unless as of a specific date therein):

 

    	 	 23	 

     

    

 

(a)         Organization;
Authority. Such Purchaser is either an individual or an entity duly incorporated or formed, validly existing and in good standing
under the laws of the jurisdiction of its incorporation or formation with full right, corporate, partnership, limited liability
company or similar power and authority to enter into and to consummate the transactions contemplated by the Transaction Documents
and otherwise to carry out its obligations hereunder and thereunder. The execution and delivery of the Transaction Documents and
performance by such Purchaser of the transactions contemplated by the Transaction Documents have been duly authorized by all necessary
corporate, partnership, limited liability company or similar action, as applicable, on the part of such Purchaser. Each Transaction
Document to which it is a party has been duly executed by such Purchaser, and when delivered by such Purchaser in accordance with
the terms hereof, will constitute the valid and legally binding obligation of such Purchaser, enforceable against it in accordance
with its terms, except: (i) as limited by general equitable principles and applicable bankruptcy, insolvency, reorganization, moratorium
and other laws of general application affecting enforcement of creditors’ rights generally, (ii) as limited by laws relating
to the availability of specific performance, injunctive relief or other equitable remedies and (iii) insofar as indemnification
and contribution provisions may be limited by applicable law.

 

(b)         Understandings
or Arrangements. Such Purchaser is acquiring the Securities as principal for its own account and has no direct or indirect
arrangement or understandings with any other persons to distribute or regarding the distribution of such Securities (this representation
and warranty not limiting such Purchaser’s right to sell the Securities pursuant to the Registration Statement or otherwise
in compliance with applicable federal and state securities laws). Such Purchaser is acquiring the Securities hereunder in the ordinary
course of its business. Such Purchaser understands that the Preferred Stock, the Conversion Shares underlying the Preferred Stock,
the Warrants and Warrant Shares are “restricted securities” and have not been registered under the Securities Act or
any applicable state securities law and is acquiring such Securities as principal for its own account and not with a view to or
for distributing or reselling such Securities or any part thereof in violation of the Securities Act or any applicable state securities
law, has no present intention of distributing any of such Securities in violation of the Securities Act or any applicable state
securities law and has no direct or indirect arrangement or understandings with any other persons to distribute or regarding the
distribution of such Securities in violation of the Securities Act or any applicable state securities law (this representation
and warranty not limiting such Purchaser’s right to sell such Securities pursuant to a registration statement or otherwise
in compliance with applicable federal and state securities laws).

 

(c)         Purchaser
Status. At the time such Purchaser was offered the Securities, it was, and as of the date hereof it is, and on each date on
which it exercises any Warrants or converts any shares of Preferred Stock it will be an “accredited investor” as defined
in Rule 501(a)(1), (a)(2), (a)(3), (a)(7) or (a)(8) under the Securities Act.

 

    	 	 24	 

     

    

 

(d)         Experience
of Such Purchaser. Such Purchaser, either alone or together with its representatives, has such knowledge, sophistication and
experience in business and financial matters so as to be capable of evaluating the merits and risks of the prospective investment
in the Securities, and has so evaluated the merits and risks of such investment. Such Purchaser is able to bear the economic risk
of an investment in the Securities and, at the present time, is able to afford a complete loss of such investment. Such Purchaser
and its advisors, if any, have been furnished with all materials relating to the business, financial condition and results of operations
of the Company, and materials relating to the offer and sale of the Securities, that have been requested by such Purchaser or its
advisors, if any. Such Purchaser acknowledges and understands that its investment in the Securities involves a significant degree
of risk.

 

(e)         Access
to Information. Such Purchaser acknowledges that it has had the opportunity to review the Transaction Documents (including
all exhibits and schedules thereto) and the SEC Reports and has been afforded (i) the opportunity to ask such questions as it has
deemed necessary of, and to receive answers from, representatives of the Company concerning the terms and conditions of the offering
of the Securities and the merits and risks of investing in the Securities; (ii) access to information about the Company and its
financial condition, results of operations, business, properties, management and prospects sufficient to enable it to evaluate
its investment; and (iii) the opportunity to obtain such additional information that the Company possesses or can acquire without
unreasonable effort or expense that is necessary to make an informed investment decision with respect to the investment. 
Such Purchaser acknowledges and agrees that neither the Placement Agent nor any Affiliate of the Placement Agent has provided such
Purchaser with any information or advice with respect to the Securities nor is such information or advice necessary or desired. 
Neither the Placement Agent nor any Affiliate has made or makes any representation as to the Company or the quality of the Securities
and the Placement Agent and any Affiliate may have acquired non-public information with respect to the Company which such Purchaser
agrees need not be provided to it.  In connection with the issuance of the Securities to such Purchaser, neither the Placement
Agent nor any of its Affiliates has acted as a financial advisor or fiduciary to such Purchaser.

 

(f)         Certain
Transactions and Confidentiality. Other than consummating the transactions contemplated hereunder, such Purchaser has not directly
or indirectly, nor has any Person acting on behalf of or pursuant to any understanding with such Purchaser, executed any purchases
or sales, including Short Sales, of the securities of the Company during the period commencing as of the time that such Purchaser
first received a term sheet (written or oral) from the Company or any other Person representing the Company setting forth the material
terms of the transactions contemplated hereunder and ending immediately prior to the execution hereof. Notwithstanding the foregoing,
in the case of a Purchaser that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions
of such Purchaser’s assets and the portfolio managers have no direct knowledge of the investment decisions made by the portfolio
managers managing other portions of such Purchaser’s assets, the representation set forth above shall only apply with respect
to the portion of assets managed by the portfolio manager that made the investment decision to purchase the Securities covered
by this Agreement. Other than to other Persons party to this Agreement, such Purchaser has maintained the confidentiality of all
disclosures made to it in connection with this transaction (including the existence and terms of this transaction). Notwithstanding
the foregoing, for avoidance of doubt, nothing contained herein shall constitute a representation or warranty, or preclude any
actions, with respect to the identification of the availability of, or securing of, available shares to borrow in order to effect
Short Sales or similar transactions in the future.

 

    	 	 25	 

     

    

 

(g)         General
Solicitation. Such Purchaser is not purchasing the Securities as a result of any advertisement, article, notice or other communication
regarding the Securities published in any newspaper, magazine or similar media or broadcast over television or radio or presented
at any seminar or any other general solicitation or general advertisement.

 

The Company acknowledges and agrees that the
representations contained in Section 3.2 shall not modify, amend or affect such Purchaser’s right to rely on the Company’s
representations and warranties contained in this Agreement or any representations and warranties contained in any other Transaction
Document or any other document or instrument executed and/or delivered in connection with this Agreement or the consummation of
the transaction contemplated hereby.

 

ARTICLE IV.

OTHER AGREEMENTS OF THE PARTIES

 

4.1         Transfer Restrictions.

 

(a)         The Securities
may only be disposed of in compliance with state and federal securities laws. In connection with any transfer of Securities other
than pursuant to an effective registration statement or Rule 144, to the Company or to an Affiliate of a Purchaser or in connection
with a pledge as contemplated in Section 4.1(b), the Company may require the transferor thereof to provide to the Company an opinion
of counsel selected by the transferor and reasonably acceptable to the Company, the form and substance of which opinion shall be
reasonably satisfactory to the Company, to the effect that such transfer does not require registration of such transferred Securities
under the Securities Act. As a condition of transfer, any such transferee shall agree in writing to be bound by the terms of this
Agreement and the Registration Rights Agreement and shall have the rights and obligations of a Purchaser under this Agreement and
the Registration Rights Agreement.

 

(b)         The Purchasers
agree to the imprinting, so long as is required by this Section 4.1, of a legend on any of the Securities in the following form:

 

[NEITHER] THIS
SECURITY [NOR THE SECURITIES INTO WHICH THIS SECURITY IS [EXERCISABLE] [CONVERTIBLE]] HAS [NOT] BEEN REGISTERED WITH THE SECURITIES
AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES
ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN
EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT
TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS. THIS SECURITY
[AND THE SECURITIES ISSUABLE UPON [EXERCISE] [CONVERSION] OF THIS SECURITY] MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN
ACCOUNT WITH A REGISTERED BROKER-DEALER OR OTHER LOAN WITH A FINANCIAL INSTITUTION THAT IS AN “ACCREDITED INVESTOR”
AS DEFINED IN RULE 501(a) UNDER THE SECURITIES ACT OR OTHER LOAN SECURED BY SUCH SECURITIES.

 

    	 	 26	 

     

    

 

The Company acknowledges
and agrees that a Purchaser may from time to time pledge pursuant to a bona fide margin agreement with a registered broker-dealer
or grant a security interest in some or all of the Securities to a financial institution that is an “accredited investor”
as defined in Rule 501(a) under the Securities Act and, if required under the terms of such arrangement, such Purchaser may transfer
pledged or secured Securities to the pledgees or secured parties. Such a pledge or transfer would not be subject to approval of
the Company and no legal opinion of legal counsel of the pledgee, secured party or pledgor shall be required in connection therewith.
Further, no notice shall be required of such pledge. At the appropriate Purchaser’s expense, the Company will execute and
deliver such reasonable documentation as a pledgee or secured party of Securities may reasonably request in connection with a pledge
or transfer of the Securities, including, if the Securities are subject to registration pursuant to the Registration Rights Agreement,
the preparation and filing of any required prospectus supplement under Rule 424(b)(3) under the Securities Act or other applicable
provision of the Securities Act to appropriately amend the list of Selling Stockholders (as defined in the Registration Rights
Agreement) thereunder.

 

(c)         Certificates
evidencing the Underlying Shares shall not contain any legend (including the legend set forth in Section 4.1(b) hereof): (i) while
a registration statement (including the Registration Statement) covering the resale of such security is effective under the Securities
Act, (ii) following any sale of such Underlying Shares pursuant to Rule 144, (iii) if such Underlying Shares are eligible for sale
under Rule 144, without the requirement for the Company to be in compliance with the current public information required under
Rule 144 as to such Underlying Shares and without volume or manner-of-sale restrictions or (iv) if such legend is not required
under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff
of the Commission). The Company shall cause its counsel to issue a legal opinion to the Transfer Agent promptly after the Effective
Date if required by the Transfer Agent to effect the removal of the legend hereunder. If all or any shares of Preferred Stock are
converted or any portion of a Warrant is exercised at a time when there is an effective registration statement to cover the resale
of the Underlying Shares, or if such Underlying Shares may be sold under Rule 144 and the Company is then in compliance with the
current public information required under Rule 144, or if the Underlying Shares may be sold under Rule 144 without the requirement
for the Company to be in compliance with the current public information required under Rule 144 as to such Underlying Shares and
without volume or manner-of-sale restrictions or if such legend is not otherwise required under applicable requirements of the
Securities Act (including judicial interpretations and pronouncements issued by the staff of the Commission) then such Underlying
Shares shall be issued free of all legends. The Company agrees that following the Effective Date or at such time as such legend
is no longer required under this Section 4.1(c), it will, no later than the earlier of (i) three (3) Trading Days and (ii) the
number of Trading Days comprising the Standard Settlement Period (as defined below) following the delivery by a Purchaser to the
Company or the Transfer Agent of a certificate representing Underlying Shares, as applicable, issued with a restrictive legend
(such third Trading Day, the “Legend Removal Date”), deliver or cause to be delivered to such Purchaser a certificate
representing such shares that is free from all restrictive and other legends, provided that, upon written request by the Company,
the Purchaser delivers a certificate as to the factual basis for removing the legend at the time of such request. The Company may
not make any notation on its records or give instructions to the Transfer Agent that enlarge the restrictions on transfer set forth
in this Section 4. Certificates for Underlying Shares subject to legend removal hereunder shall be transmitted by the Transfer
Agent to the Purchaser by crediting the account of the Purchaser’s prime broker with the Depository Trust Company System
as directed by such Purchaser. As used herein, “Standard Settlement Period” means the standard settlement period,
expressed in a number of Trading Days, on the Company’s primary Trading Market with respect to the Common Stock as in effect
on the date of delivery of a certificate representing Underlying Shares, as applicable, issued with a restrictive legend.

 

    	 	 27	 

     

    

 

(d)         In addition
to such Purchaser’s other available remedies, the Company shall pay to a Purchaser, in cash, (i) as partial liquidated damages
and not as a penalty, for each $1,000 of Underlying Shares (based on the VWAP of the Common Stock on the date such Securities are
submitted to the Transfer Agent) delivered for removal of the restrictive legend and subject to Section 4.1(c), $10 per Trading
Day (increasing to $20 per Trading Day five (5) Trading Days after such damages have begun to accrue) for each Trading Day after
the Legend Removal Date until such certificate is delivered without a legend and (ii) if the Company fails to (a) issue and deliver
(or cause to be delivered) to a Purchaser by the Legend Removal Date a certificate representing the Securities so delivered to
the Company by such Purchaser that is free from all restrictive and other legends and (b) if after the Legend Removal Date such
Purchaser purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by
such Purchaser 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 that such Purchaser anticipated receiving from the Company without
any restrictive legend, then, an amount equal to the excess of such Purchaser’s total purchase price (including brokerage
commissions and other out-of-pocket expenses, if any) for the shares of Common Stock so purchased (including brokerage commissions
and other out-of-pocket expenses, if any) (the “Buy-In Price”) over the product of (x) such number of Underlying
Shares that the Company was required to deliver to such Purchaser by the Legend Removal Date multiplied by (y) the lowest closing
sale price of the Common Stock on any Trading Day during the period commencing on the date of the delivery by such Purchaser to
the Company of the applicable Underlying Shares (as the case may be) and ending on the date of such delivery and payment under
this clause (ii). 

 

    	 	 28	 

     

    

 

(e)         Each Purchaser,
severally and not jointly with the other Purchasers, agrees with the Company that such Purchaser will sell or transfer any Securities
pursuant to either the registration requirements of the Securities Act, including any applicable prospectus delivery requirements,
or an exemption therefrom, and that if Securities are sold pursuant to a Registration Statement, they will be sold in compliance
with the plan of distribution set forth therein, and acknowledges that the removal of the restrictive legend from certificates
representing Securities as set forth in this Section 4.1 is predicated upon the Company’s reliance upon this understanding.

 

4.2         Acknowledgment
of Dilution. The Company acknowledges that the issuance of the Securities may result in dilution of the outstanding shares
of Common Stock, which dilution may be substantial under certain market conditions. The Company further acknowledges that its obligations
under the Transaction Documents, including, without limitation, its obligation to issue the Underlying Shares pursuant to the Transaction
Documents, are unconditional and absolute and not subject to any right of set off, counterclaim, delay or reduction, regardless
of the effect of any such dilution or any claim the Company may have against any Purchaser and regardless of the dilutive effect
that such issuance may have on the ownership of the other stockholders of the Company.

 

4.3         Furnishing of
Information; Public Information.

 

(a)         Until
no Purchaser owns Securities, the Company covenants to maintain the registration of the Common Stock under Section 12(b) or 12(g)
of the Exchange Act and to timely file (or obtain extensions in respect thereof and file within the applicable grace period) all
reports required to be filed by the Company after the date hereof pursuant to the Exchange Act even if the Company is not then
subject to the reporting requirements of the Exchange Act. As long as any Purchaser owns Securities, if the Company is not required
to file reports pursuant to the Exchange Act, it will prepare and furnish to the Purchasers and make publicly available in accordance
with Rule 144(c) such information as is required for the Purchasers to sell the Securities, including without limitation, under
Rule 144. The Company further covenants that it will take such further action as any holder of Securities may reasonably request,
to the extent required from time to time to enable such Person to sell such Securities without registration under the Securities
Act, including without limitation, within the requirements of the exemption provided by Rule 144.

 

    	 	 29	 

     

    

 

(b)          At any
time during the period commencing from the six (6) month anniversary of the date hereof and ending at such time that all of the
Securities may be sold without the requirement for the Company to be in compliance with Rule 144(c)(1) and otherwise without restriction
or limitation pursuant to Rule 144, if the Company shall fail for any reason to satisfy the current public information requirement
under Rule 144(c) (a “Public Information Failure”) then, in addition to such Purchaser’s other available
remedies, the Company shall pay to a Purchaser, in cash, as partial liquidated damages and not as a penalty, by reason of any such
delay in or reduction of its ability to sell the Securities, an amount in cash equal to two percent (2.0%) of the aggregate Subscription
Amount of such Purchaser’s Securities on the day of a Public Information Failure and on every thirtieth (30th)
day (pro rated for periods totaling less than thirty days) thereafter until the earlier of (a) the date such Public Information
Failure is cured and (b) such time that such public information is no longer required  for the Purchasers to transfer the
Underlying Shares pursuant to Rule 144.  The payments to which a Purchaser shall be entitled pursuant to this Section 4.3(b)
are referred to herein as “Public Information Failure Payments.”  Public Information Failure Payments
shall be paid on the earlier of (i) the last day of the calendar month during which such Public Information Failure Payments
are incurred and (ii) the third (3rd) Business Day after the event or failure giving rise to the Public Information
Failure Payments is cured.  In the event the Company fails to make Public Information Failure Payments in a
timely manner, such Public Information Failure Payments shall bear interest at the rate of 1.5% per month (prorated for
partial months) until paid in full. Nothing herein shall limit such Purchaser’s right to pursue actual damages for the Public
Information Failure, and such Purchaser shall have the right to pursue all remedies available to it at law or in equity including,
without limitation, a decree of specific performance and/or injunctive relief.

 

4.4         Integration.
The Company shall not sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined
in Section 2 of the Securities Act) that would be integrated with the offer or sale of the Securities in a manner that would require
the registration under the Securities Act of the sale of the Securities or that would be integrated with the offer or sale of the
Securities for purposes of the rules and regulations of any Trading Market such that it would require shareholder approval prior
to the closing of such other transaction unless shareholder approval is obtained before the closing of such subsequent transaction.

 

4.5         Conversion and
Exercise Procedures. Each of the form of Notice of Exercise included in the Warrants and the form of Notice of Conversion included
in the Certificate of Designation set forth the totality of the procedures required of the Purchasers in order to exercise the
Warrants or convert the Preferred Stock. Without limiting the preceding sentences, no ink-original Notice of Exercise or Notice
of Conversion shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice of
Exercise or Notice of Conversion form be required in order to exercise the Warrants or convert the Preferred Stock. No additional
legal opinion, other information or instructions shall be required of the Purchasers to exercise their Warrants or convert their
Preferred Stock. The Company shall honor exercises of the Warrants and conversions of the Preferred Stock and shall deliver Underlying
Shares in accordance with the terms, conditions and time periods set forth in the Transaction Documents.

any of their respective officers, directors, employees or agents in connection with the transactions contemplated by the Transaction

any such public statement without the prior consent of the Company, with respect to any press release of any Purchaser, or without
the prior consent of each Purchaser, with respect to any press release of the Company, which consent shall not unreasonably be
withheld or delayed, except if such disclosure is required by law, in which case the disclosing party shall promptly provide the
other party with prior notice of such public statement or communication. Notwithstanding the foregoing, the Company shall not publicly
disclose the name of any Purchaser, or include the name of any Purchaser in any filing with the Commission or any regulatory agency
or Trading Market, without the prior written consent of such Purchaser, except: (a) as required by federal securities law in connection
with (i) any registration statement contemplated by the Registration Rights Agreement and (ii) the filing of final Transaction
Documents with the Commission and (b) to the extent such disclosure is required by law or Trading Market regulations, in which
case the Company shall provide the Purchasers with prior notice of such disclosure permitted under this clause (b).

 

4.7         Shareholder Rights
Plan. No claim will be made or enforced by the Company or, with the consent of the Company, any other Person, that any Purchaser
is an “Acquiring Person” under any control share acquisition, business combination, poison pill (including any distribution
under a rights agreement) or similar anti-takeover plan or arrangement in effect or hereafter adopted by the Company, or that any
Purchaser could be deemed to trigger the provisions of any such plan or arrangement, by virtue of receiving Securities under the
Transaction Documents or under any other agreement between the Company and the Purchasers.

 

4.8         Non-Public Information.
Except with respect to the material terms and conditions of the transactions contemplated by the Transaction Documents, the Company
covenants and agrees that neither it, nor any other Person acting on its behalf, will provide any Purchaser or its agents or counsel
with any information that the Company believes constitutes material non-public information, unless prior thereto such Purchaser
shall have entered into a written agreement with the Company regarding the confidentiality and use of such information. The Company
understands and confirms that each Purchaser shall be relying on the foregoing covenant in effecting transactions in securities
of the Company.

 

4.9         Use of Proceeds.
The Company shall use the net proceeds from the sale of the Securities hereunder for working capital purposes and shall not use

ordinary course of the Company’s business and prior practices), (b) for the redemption of any Common Stock or Common Stock
Equivalents, (c) for the settlement of any outstanding litigation or (d) in violation of FCPA or OFAC regulations.

 

    	 	 31	 

     

    

 

4.10         Indemnification
of Purchasers. Subject to the provisions of this Section 4.10, the Company will indemnify and hold each Purchaser and its directors,
officers, shareholders, members, partners, employees and agents (and any other Persons with a functionally equivalent role of a
Person holding such titles notwithstanding a lack of such title or any other title), each Person who controls such Purchaser (within
the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, shareholders,
agents, members, partners or employees (and any other Persons with a functionally equivalent role of a Person holding such titles
notwithstanding a lack of such title or any other title) of such controlling persons (each, a “Purchaser Party”)
harmless from any and all losses, liabilities, obligations, claims, contingencies, damages, costs and expenses, including all judgments,
amounts paid in settlements, court costs and reasonable attorneys’ fees and costs of investigation that any such Purchaser
Party may suffer or incur as a result of or relating to (a) any breach of any of the representations, warranties, covenants or
agreements made by the Company in this Agreement or in the other Transaction Documents or (b) any action instituted against Purchaser
Parties in any capacity, or any of them or their respective Affiliates, by any stockholder of the Company who is not an Affiliate
of such Purchaser Party, with respect to any of the transactions contemplated by the Transaction Documents (unless such action
is based upon a breach of such Purchaser Party’s representations, warranties or covenants under the Transaction Documents
or any agreements or understandings such Purchaser Party may have with any such stockholder or any violations by such Purchaser
Party of state or federal securities laws or any conduct by such Purchaser Party which constitutes fraud, gross negligence, willful
misconduct or malfeasance). If any action shall be brought against any Purchaser Party in respect of which indemnity may be sought
pursuant to this Agreement, such Purchaser Party shall promptly notify the Company in writing, and the Company shall have the right
to assume the defense thereof with counsel of its own choosing reasonably acceptable to the Purchaser Party. Any Purchaser Party
shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses
of such counsel shall be at the expense of such Purchaser Party except to the extent that (i) the employment thereof has been specifically
authorized by the Company in writing, (ii) the Company has failed after a reasonable period of time to assume such defense and
to employ counsel or (iii) in such action there is, in the reasonable opinion of counsel, a material conflict on any material issue
between the position of the Company and the position of such Purchaser Party, in which case the Company shall be responsible for
the reasonable fees and expenses of no more than one such separate counsel. The Company will not be liable to any Purchaser Party
under this Agreement (y) for any settlement by a Purchaser Party effected without the Company’s prior written consent, which
shall not be unreasonably withheld or delayed; or (z) to the extent, but only to the extent that a loss, claim, damage or liability
is attributable to any Purchaser Party’s breach of any of the representations, warranties, covenants or agreements made by
such Purchaser Party in this Agreement or in the other Transaction Documents. The indemnification required by this Section 4.10
shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are
received or are incurred. The indemnity agreements contained herein shall be in addition to any cause of action or similar right
of any Purchaser Party against the Company or others and any liabilities the Company may be subject to pursuant to law.

 

4.11         Reservation
and Listing of Securities.

 

(a)         The Company
shall maintain a reserve from its duly authorized shares of Common Stock for issuance pursuant to the Transaction Documents in
such amount as may then be required to fulfill its obligations in full under the Transaction Documents.

 

    	 	 32	 

     

    

 

(b)         If, on
any date, the number of authorized but unissued (and otherwise unreserved) shares of Common Stock is less than 130% of (i) the
Required Minimum on such date, minus (ii) the number of shares of Common Stock previously issued pursuant to the Transaction Documents,
then the Board of Directors shall use commercially reasonable efforts to amend the Company’s certificate or articles of incorporation
to increase the number of authorized but unissued shares of Common Stock to at least the Required Minimum at such time (minus the
number of shares of Common Stock previously issued pursuant to the Transaction Documents), as soon as possible and in any event
not later than the 75th day after such date; provided that the Company will not be required at any time to authorize
a number of shares of Common Stock greater than the maximum remaining number of shares of Common Stock that could possibly be issued
after such time pursuant to the Transaction Documents.

 

(c)         The Company
shall, if applicable: (i) in the time and manner required by the principal Trading Market, prepare and file with such Trading Market
an additional shares listing application covering a number of shares of Common Stock at least equal to the Required Minimum on
the date of such application, (ii) take all steps necessary to cause such shares of Common Stock to be approved for listing or
quotation on such Trading Market as soon as possible thereafter, (iii) provide to the Purchasers evidence of such listing or quotation
and (iv) maintain the listing or quotation of such Common Stock on any date at least equal to the Required Minimum on such date
on such Trading Market or another Trading Market. The Company agrees to maintain the eligibility of the Common Stock for electronic
transfer through the Depository Trust Company or another established clearing corporation, including, without limitation, by timely
payment of fees to the Depository Trust Company or such other established clearing corporation in connection with such electronic
transfer. In addition, the Company shall hold a special meeting of shareholders (which may also be at the annual meeting of shareholders)
on or before March 31, 2017 for the purpose of obtaining Shareholder Approval, with the recommendation of the Company’s Board
of Directors that such proposal be approved, and the Company shall solicit proxies from its shareholders in connection therewith
in the same manner as all other management proposals in such proxy statement and all management-appointed proxyholders shall vote
their proxies in favor of such proposal. The Company shall use its reasonable best efforts to obtain such Shareholder Approval.
If the Company does not obtain Shareholder Approval at the first meeting, the Company shall call a meeting every four months thereafter
to seek Shareholder Approval until the earlier of the date Shareholder Approval is obtained or the Preferred Stock is no longer
outstanding.

 

4.12         Adjustment to
Repriced Securities; Extension of Warrants.

 

(a)         Adjustment to Repriced Securities.

 

(1)         Immediate
Warrant Adjustment. Immediately upon execution of this Agreement, exercise price of the Common Stock Purchase Warrants set
forth on Schedule I attached hereto under the title “Immediately Repriced Warrants” shall be reduced to $0.92
provided that such warrants shall be non-exercisable for 6 months and 1 day following the date hereof and the Termination Date
thereof shall be extended for 6 months and 1 day.

 

    	 	 33	 

     

    

 

(2)         Shareholder
Approval Adjustment. Within two business days of the date that Shareholder Approval is approved and deemed effective (“Shareholder
Approval Date”), the conversion price or exercise price, as applicable, of all Repriced Securities shall be reduced,
and only reduced, to equal $0.70 (“Reset Price”), subject to adjustment for reverse and forward stock splits,
stock dividends, stock combinations and other similar transactions of the Common Stock that occur after the date of this Agreement.
Additionally, on the Shareholder Approval Date, the Company shall issue to the Purchaser, for no additional consideration thereon,
additional shares of Common Stock (“Reprice Shares”) in respect of any conversions or exercises made by such
Purchaser in respect of any Repriced Security after December 19, 2016 (“Prior Conversions”, which Prior Conversions
shall be deemed to include the requested conversions into 550,000 shares of Common Stock made immediately following December 19,
2016) equal to the number of shares of Common Stock, in the aggregate, that would have been issued in such Prior Conversions at
the Reset Price, less any shares of Common Stock actually issued. Within two business days of the Shareholder Approval Date, the
Company shall file any required prospectus supplements in respect of the Repriced Securities and the Reprice Shares shall be issued
free of any legends or resale restrictions. Delivery of Reprice Shares shall otherwise be governed by Section 4.1 as if such Reprice
Securities were Underlying Securities. In implementation of the foregoing, to the extent that an issuance of Reprice Shares would
result in a Purchaser or any of its affiliates beneficially owning in excess of 4.99% (the “Maximum Percentage”)
of the Common Stock, then the Company shall initially issue only such number of Reprice Shares that would result in such Purchaser
(together with such Purchaser’s affiliates) beneficially owning the Maximum Percentage of the Common Stock, and, except as
otherwise provided below, no other Reprice Shares shall be issuable under this Section 4.12 but instead held in abeyance by the
Company for the benefit of the Purchaser. After such initial issuance, and until all Reprice Shares which otherwise would have
been issued under this Section 4.12 have been issued, from time to time the Company will issue such number of such unissued Reprice
Shares so that such Purchaser (together such Purchaser’s affiliates) will beneficially own only the Maximum Percentage of
the Common Stock. Such Purchaser shall make written representations and warranties to the Company regarding its (together with
its affiliates’) beneficial ownership to effectuate the foregoing. The Maximum Percentage limitation contained in this paragraph
and the limitation on exercise contained in Section 2(e) of the Warrants issued to such Purchaser pursuant to this Agreement shall
be coordinated so that the aggregate beneficial ownership of such Purchaser (together with its affiliates) does not exceed the
Maximum Percentage limitation. The provisions of this paragraph shall be implemented in a manner otherwise than in strict conformity
with the terms of this paragraph to correct this paragraph (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 paragraph shall apply
to assignees of such Purchaser hereunder. For the purposes of this paragraph, 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.

 

    	 	 34	 

     

    

 

(b)         Extended
Warrants. The Common Stock Purchase Warrants set forth on Schedule I under the heading “Extended Warrants”
are hereby extended such that the Termination Date thereof is June 28, 2022. Within two business days of the date hereof, the Company
shall file any required prospectus supplements to any resale registration statement registering such Common Stock Purchase Warrants
reflecting such extension.

 

(c)         Replacement
Warrants. The Company covenants that upon receipt by the Company of a request of a Purchaser of a new certificate evidencing
any Repriced Securities that are Common Stock Purchase Warrants amended under this Section 4.12, and upon surrender of such Common
Stock Purchase Warrant certificate, the Company will make and deliver a new Common Stock Purchase Warrant certificate reflecting
the terms amended under this Section 4.12.

 

(d)         The Company
understands and confirms that each Purchaser shall be relying on the foregoing covenantS in effecting transactions in securities
of the Company after the date hereof.

 

4.13         Subsequent Equity
Sales.

 

(a)         From the
date hereof until the date that is the earlier of (1) provided that the Resale Regitration Statement is then effective as to all
of the Registration Securities (as defined in the Registration Rights Agreement), one hundred fifty (150) days after the Closing
Date and (2) 60 days following the Effective Date, neither the Company nor any Subsidiary shall issue, enter into any agreement
to issue or announce the issuance or proposed issuance of any shares of Common Stock or Common Stock Equivalents, provided that,
following the ninetieth (90th) day after the effective date of the Resale Registration Statement, on any date that the
Purchasers hold less than 50% in interest of the Preferred Stock issued at each Closing, this Section 4.13(a) shall no longer apply.

 

(b)         From the
date hereof until such time as no Purchaser holds any of the Warrants, the Company shall be prohibited from effecting or entering
into an agreement to effect any issuance by the Company or any of its Subsidiaries of Common Stock or Common Stock Equivalents
(or a combination of units thereof) involving a Variable Rate Transaction. “Variable Rate Transaction” means
a transaction in which the Company (i) issues or sells any debt or equity securities that are convertible into, exchangeable or
exercisable for, or include the right to receive, additional shares of Common Stock either (A) at a conversion price, exercise
price or exchange rate or other price that is based upon, and/or varies with, the trading prices of or quotations for the shares
of Common Stock at any time after the initial issuance of such debt or equity securities or (B) with a conversion, exercise or
exchange price that is subject to being reset at some future date after the initial issuance of such debt or equity security or
upon the occurrence of specified or contingent events directly or indirectly related to the business of the Company or the market
for the Common Stock or (ii) enters into any agreement, including, but not limited to, an equity line of credit, whereby the Company
may issue securities at a future determined price. For purposes of clarity, a Variable Rate Transaction shall include any drawdown
on any existing or future at-the-market facility or equity line agreement of the Company. Any Purchaser shall be entitled to obtain
injunctive relief against the Company to preclude any such issuance, which remedy shall be in addition to any right to collect
damages.

 

    	 	 35	 

     

    

 

(c)         Unless
Shareholder Approval has been obtained and deemed effective, neither the Company nor any Subsidiary shall make any issuance whatsoever
of Common Stock or Common Stock Equivalents. Any Purchaser shall be entitled to obtain injunctive relief against the Company to
preclude any such issuance, which remedy shall be in addition to any right to collect damages.

 

(d)         Notwithstanding
the foregoing, this Section 4.13 shall not apply in respect of an Exempt Issuance, except that no Variable Rate Transaction shall
be an Exempt Issuance. 

 

4.14         Equal Treatment
of Purchasers. No consideration (including any modification of any Transaction Document) shall be offered or paid to any Person
to amend or consent to a waiver or modification of any provision of this Agreement unless the same consideration is also offered
to all of the parties to this Agreement. For clarification purposes, this provision constitutes a separate right granted to each
Purchaser by the Company and negotiated separately by each Purchaser, and is intended for the Company to treat the Purchasers as
a class and shall not in any way be construed as the Purchasers acting in concert or as a group with respect to the purchase, disposition
or voting of Securities or otherwise.

 

4.15         Certain Transactions
and Confidentiality. Each Purchaser, severally and not jointly with the other Purchasers, covenants that neither it, nor any
Affiliate acting on its behalf or pursuant to any understanding with it will execute any purchases or sales, including Short Sales,
of any of the Company’s securities during the period commencing with the execution of this Agreement and ending at such time
that the transactions contemplated by this Agreement are first publicly announced pursuant to the initial press release as described
in Section 4.6.  Each Purchaser, severally and not jointly with the other Purchasers, covenants that until such time as the
transactions contemplated by this Agreement are publicly disclosed by the Company pursuant to the initial press release as described
in Section 4.6, such Purchaser will maintain the confidentiality of the existence and terms of this transaction and the information
included in the Transaction Documents and the Disclosure Schedules. Notwithstanding the foregoing, and notwithstanding anything
contained in this Agreement to the contrary, the Company expressly acknowledges and agrees that (i) no Purchaser makes any representation,
warranty or covenant hereby that it will not engage in effecting transactions in any securities of the Company after the time that
the transactions contemplated by this Agreement are first publicly announced pursuant to the initial press release as described
in Section 4.6, (ii) no Purchaser shall be restricted or prohibited from effecting any transactions in any securities of the Company
in accordance with applicable securities laws from and after the time that the transactions contemplated by this Agreement are
first publicly announced pursuant to the initial press release as described in Section 4.6 and (iii) no Purchaser shall have any
duty of confidentiality to the Company or its Subsidiaries after the issuance of the initial press release as described in Section
4.6.  Notwithstanding the foregoing, in the case of a Purchaser that is a multi-managed investment vehicle whereby separate
portfolio managers manage separate portions of such Purchaser’s assets and the portfolio managers have no direct knowledge
of the investment decisions made by the portfolio managers managing other portions of such Purchaser’s assets, the covenant
set forth above shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment
decision to purchase the Securities covered by this Agreement.

 

    	 	 36	 

     

    

 

4.16         Capital Changes.
Until the one year anniversary of the Second Closing Date, the Company shall not undertake a reverse or forward stock split or
reclassification of the Common Stock without the prior written consent of the Purchasers holding a majority in interest of the
shares of Preferred Stock, provided that this Section 4.16 shall not apply solely in connection with any reverse stock split that
is conducted in order to meet or maintain compliance with the listing standards of any Trading Market.

 

ARTICLE V.

MISCELLANEOUS

 

5.1         Termination. 
This Agreement may be terminated by any Purchaser, as to such Purchaser’s obligations hereunder only and without any effect
whatsoever on the obligations between the Company and the other Purchasers, by written notice to the other parties, if the First
Closing has not been consummated on or before December 28, 2016; provided, however, that such termination will not
affect the right of any party to sue for any breach by any other party (or parties).

 

5.2         Fees and Expenses.
Except as expressly set forth in the Transaction Documents to the contrary, each party shall pay the fees and expenses of its advisers,
counsel, accountants and other experts, if any, and all other expenses incurred by such party incident to the negotiation, preparation,
execution, delivery and performance of this Agreement. The Company shall pay all Transfer Agent fees (including, without limitation,
any fees required for same-day processing of any instruction letter delivered by the Company and any conversion or exercise notice
delivered by a Purchaser), stamp taxes and other taxes and duties levied in connection with the delivery of any Securities to the
Purchasers.

 

5.3         Entire Agreement.
The Transaction Documents, together with the exhibits and schedules thereto, contain the entire understanding of the parties with
respect to the subject matter hereof and thereof and supersede all prior agreements and understandings, oral or written, with respect
to such matters, which the parties acknowledge have been merged into such documents, exhibits and schedules.

 

    	 	 37

5.5         Amendments; Waivers.
No provision of this Agreement may be waived, modified, supplemented or amended except in a written instrument signed, in the case
of an amendment, by the Company and the Purchasers holding at least 67% in interest of the Preferred Stock based on the initial
Subscription Amounts hereunder or, in the case of a waiver, by the party against whom enforcement of any such waived provision
is sought. No waiver of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to
be a continuing waiver in the future or a waiver of any subsequent default or a waiver of any other provision, condition or requirement
hereof, nor shall any delay or omission of any party to exercise any right hereunder in any manner impair the exercise of any such
right.

 

5.6         Headings.
The headings herein are for convenience only, do not constitute a part of this Agreement and shall not be deemed to limit or affect
any of the provisions hereof.

 

5.7         Successors and
Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their successors and permitted assigns.
The Company may not assign this Agreement or any rights or obligations hereunder without the prior written consent of each Purchaser
(other than by merger). Any Purchaser may assign any or all of its rights under this Agreement to any Person to whom such Purchaser
assigns or transfers any Securities, provided that such transferee agrees in writing to be bound, with respect to the transferred
Securities, by the provisions of the Transaction Documents that apply to the “Purchasers.”

Beneficiaries. The Placement Agent shall be third party beneficiaries with respect to the representations and warranties of
the Company in Section 3.1 hereof and the representations and warranties of the Purchasers in Section 3.2 hereof. This Agreement
is intended for the benefit of the parties hereto and their respective successors and permitted assigns and is not for the benefit
of, nor may any provision hereof be enforced by, any other Person, except as otherwise set forth in Section 4.10 and this Section
5.8.

 

    	 	 38	 

     

    

 

5.9         Governing Law.
All questions concerning the construction, validity, enforcement and interpretation of the Transaction Documents shall be governed
by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the principles of
conflicts of law thereof. Each party agrees that all legal proceedings concerning the interpretations, enforcement and defense
of the transactions contemplated by this Agreement and any other Transaction Documents (whether brought against a party hereto
or its respective affiliates, directors, officers, shareholders, partners, members, employees or agents) shall be commenced exclusively
in the state and federal courts sitting in the City of New York. Each party hereby irrevocably submits to the exclusive jurisdiction
of the state and federal courts sitting in the City of New York, Borough of Manhattan for the adjudication of any dispute hereunder
or in connection herewith or with any transaction contemplated hereby or discussed herein (including with respect to the enforcement
of any of the Transaction Documents), and hereby irrevocably waives, and agrees not to assert in any action, suit or proceeding,
any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is improper
or is an inconvenient venue for such proceeding. Each party hereby irrevocably waives personal service of process and consents
to process being served in any such suit, action or proceeding by mailing a copy thereof via registered or certified mail or overnight
delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Agreement and agrees that
such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed
to limit in any way any right to serve process in any other manner permitted by law. If either party shall commence an action,
suit or proceeding to enforce any provisions of the Transaction Documents, then, in addition to the obligations of the Company
under Section 4.10, the prevailing party in such action, suit or proceeding shall be reimbursed by the other party for its reasonable
attorneys’ fees and other costs and expenses incurred with the investigation, preparation and prosecution of such action
or proceeding.

 

5.10         Survival.
The representations and warranties contained herein shall survive the applicable Closing and the delivery of the Securities.

 

5.11         Execution.
This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered one and the same
agreement and shall become effective when counterparts have been signed by each party and delivered to each other party, it being
understood that the parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission
or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and binding obligation of the
party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or “.pdf”
signature page were an original thereof.

 

5.12         Severability.
If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, illegal,
void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full
force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall use their commercially
reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated
by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the parties that
they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be
hereafter declared invalid, illegal, void or unenforceable.

 

    	 	 39	 

     

    

 

5.13         Rescission and
Withdrawal Right. Notwithstanding anything to the contrary contained in (and without limiting any similar provisions of) any
of the other Transaction Documents, whenever any Purchaser exercises a right, election, demand or option under a Transaction Document
and the Company does not timely perform its related obligations within the periods therein provided, then such Purchaser may rescind
or withdraw, in its sole discretion from time to time upon written notice to the Company, any relevant notice, demand or election
in whole or in part without prejudice to its future actions and rights; provided, however, that in the case of a
rescission of a conversion of the Preferred Stock or exercise of a Warrant, the applicable Purchaser shall be required to return
any shares of Common Stock subject to any such rescinded conversion or exercise notice concurrently with the return to such Purchaser
of the aggregate exercise price paid to the Company for such shares and the restoration of such Purchaser’s right to acquire
such shares pursuant to such Purchaser’s Warrant (including, issuance of a replacement warrant certificate evidencing such
restored right).

 

5.14         Replacement
of Securities. If any certificate or instrument evidencing any Securities is mutilated, lost, stolen or destroyed, the Company
shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof (in the case of mutilation), or
in lieu of and substitution therefor, a new certificate or instrument, but only upon receipt of evidence reasonably satisfactory
to the Company of such loss, theft or destruction. The applicant for a new certificate or instrument under such circumstances shall
also pay any reasonable third-party costs (including customary indemnity) associated with the issuance of such replacement Securities.

 

5.15         Remedies.
In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, each of
the Purchasers and the Company will be entitled to specific performance under the Transaction Documents. The parties agree that
monetary damages may not be adequate compensation for any loss incurred by reason of any breach of obligations contained in the
Transaction Documents and hereby agree to waive and not to assert in any action for specific performance of any such obligation
the defense that a remedy at law would be adequate.

 

5.16         Payment Set
Aside. To the extent that the Company makes a payment or payments to any Purchaser pursuant to any Transaction Document or
a Purchaser enforces or exercises its rights thereunder, and such payment or payments or the proceeds of such enforcement or exercise
or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside, recovered from, disgorged
by or are required to be refunded, repaid or otherwise restored to the Company, a trustee, receiver or any other Person under any
law (including, without limitation, any bankruptcy law, state or federal law, common law or equitable cause of action), then to
the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and continued
in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred.

 

5.17         [RESERVED]

 

    	 	 40	 

     

    

 

5.18         Independent
Nature of Purchasers’ Obligations and Rights. The obligations of each Purchaser under any Transaction Document are several
and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance
or non-performance of the obligations of any other Purchaser under any Transaction Document. Nothing contained herein or in any
other Transaction Document, and no action taken by any Purchaser pursuant hereto or thereto, shall be deemed to constitute the
Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers
are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction
Documents. Each Purchaser shall be entitled to independently protect and enforce its rights, including, without limitation, the
rights arising out of this Agreement or out of the other Transaction Documents, and it shall not be necessary for any other Purchaser
to be joined as an additional party in any proceeding for such purpose. Each Purchaser has been represented by its own separate
legal counsel in its review and negotiation of the Transaction Documents. For reasons of administrative convenience only, each
Purchaser and its respective counsel have chosen to communicate with the Company through EGS. EGS does not represent any of the
Purchasers and only represents the Placement Agent. The Company has elected to provide all Purchasers with the same terms and Transaction
Documents for the convenience of the Company and not because it was required or requested to do so by any of the Purchasers.

 

5.19         Liquidated Damages.
The Company’s obligations to pay any partial liquidated damages or other amounts owing under the Transaction Documents is
a continuing obligation of the Company and shall not terminate until all unpaid partial liquidated damages and other amounts have
been paid notwithstanding the fact that the instrument or security pursuant to which such partial liquidated damages or other amounts
are due and payable shall have been canceled.

 

5.20         Saturdays, Sundays,
Holidays, etc.         If the last or appointed day for the taking of any action or the expiration of any right required or granted
herein shall not be a Business Day, then such action may be taken or such right may be exercised on the next succeeding Business
Day.

 

5.21         Construction.
The parties agree that each of them and/or their respective counsel have reviewed and had an opportunity to revise the Transaction
Documents and, therefore, the normal rule of construction to the effect that any ambiguities are to be resolved against the drafting
party shall not be employed in the interpretation of the Transaction Documents or any amendments thereto. In addition, each and
every reference to share prices and shares of Common Stock in any Transaction Document shall be subject to adjustment for reverse
and forward stock splits, stock dividends, stock combinations and other similar transactions of the Common Stock that occur after
the date of this Agreement.

 

5.22         WAIVER OF
JURY TRIAL. IN ANY ACTION, SUIT, OR PROCEEDING IN ANY JURISDICTION BROUGHT BY ANY PARTY AGAINST ANY OTHER PARTY, THE PARTIES
EACH KNOWINGLY AND INTENTIONALLY, TO THE GREATEST EXTENT PERMITTED BY APPLICABLE LAW, HEREBY ABSOLUTELY, UNCONDITIONALLY, IRREVOCABLY
AND EXPRESSLY WAIVES FOREVER TRIAL BY JURY.
