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
sale of the Securities will not obligate the Company to issue shares of Common Stock or other securities to any Person (other than

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 stockholders.

such registration. Except as set forth on Schedule 3.1(w), the Company has not, in the 12 months preceding the date hereof,
received notice from any Trading Market on which the Common Stock is or has been listed or quoted to the effect that the Company

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

neither the Company, nor any of its Affiliates, nor any Person acting on its or their behalf has, directly or indirectly, made
any offers or sales of any security or solicited any offers to buy any security, under circumstances that would cause this offering
of the Securities to be integrated with prior offerings by the Company for purposes of any applicable shareholder approval provisions
of any Trading Market on which any of the securities of the Company are listed or designated.

Based on the consolidated financial condition of the Company as of the Closing Date, after giving effect to the receipt by the
Company of the proceeds from the sale 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 Closing Date.

S-3 Eligibility. The Company is eligible to register the resale of the Underlying Shares for resale by the Purchaser on Form
S-3 promulgated under the Securities Act.


 


3.2          Representations
and Warranties of the Purchasers. Each Purchaser, for itself and for no other Purchaser, hereby represents and warrants as
of the date hereof and as of the Closing Date to the Company as follows (unless as of a specific date therein):


 


(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 Series A-4 Preferred Stock, the Conversion Shares underlying the Series
A-4 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).


 




    	23



    	 



    

 


(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.


 


(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)          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.


 




    	24



    	 



    

 


(f)          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           Underlying
Shares. The shares of Common Stock underlying the Series A-3 Preferred Stock shall be issued free of legends. If (i) all or
any shares of Series A-4 Preferred Stock are converted at a time when there is an effective registration statement to cover the
issuance or resale of the Conversion Shares underlying the Series A-4 Preferred Stock or Rule 144 is available for resale of such
Conversion Shares underlying the Series A-4 Preferred Stock, the Conversion Shares underlying the Series A-4 Preferred Stock issued
pursuant to any such conversion shall be issued free of all legends and (ii) all or any portion of a Warrant is exercised at a
time when there is an effective registration statement to cover the issuance or resale of the Warrant Shares or if the Warrant
is exercised via cashless exercise, the Warrant Shares issued pursuant to any such exercise shall be issued free of all legends.
If at any time following its effective date, the Resale Registration Statement (or any subsequent registration statement registering
the sale or resale of Conversion Shares underlying the Series A-4 Preferred Stock or the Warrant Shares) is not effective or is
not otherwise available for the sale or resale of the Conversion Shares underlying the Series A-4 Preferred Stock or the Warrant
Shares, the Company shall immediately notify the holders of the Series A-4 Preferred Stock and the Warrants in writing that such
Resale Registration Statement or other registration statement is not then effective and thereafter shall promptly notify such holders
when such Resale Registration Statement or other registration statement is effective again and available for the sale or resale
of the Conversion Shares underlying the Series A-4 Preferred Stock and the Warrant Shares (it being understood and agreed that
the foregoing shall not limit the ability of the Company to issue, or any Purchaser to sell, any of the Conversion Shares underlying
the Series A-4 Preferred Stock and the Warrant Shares in compliance with applicable federal and state securities laws). The Company
shall use best efforts to keep the Resale Registration Statement registering the issuance or resale of the Warrant Shares effective
during the period beginning on its effective date until the expiration of the Warrants. Upon a cashless exercise of a Warrant,
the holding period for purposes of Rule 144 shall tack back to the original date of issuance of such Warrant.


 




    	25



    	 



    

 


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.


 


(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.


 




    	26



    	 



    

 


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.


 


4.6          Securities
Laws Disclosure; Publicity. The Company shall, by 9:00 a.m. (New York City time) on the Trading Day immediately following the
date hereof, file a Current Report on Form 8-K and press release disclosing the material terms of the transactions contemplated
hereby, including the Transaction Documents as exhibits thereto. From and after the issuance of such press release, the Company
represents to the Purchasers that it shall have publicly disclosed all material, non-public information delivered to any of the
Purchasers by the Company or any of its Subsidiaries, or any of their respective officers, directors, employees or agents in connection
with the transactions contemplated by the Transaction Documents. The Company and each Purchaser shall consult with each other in
issuing any other press releases with respect to the transactions contemplated hereby, and neither the Company nor any Purchaser
shall issue any such press release nor otherwise make 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).


 




    	27



    	 



    

 


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. Except as set forth on Schedule 4.9 attached hereto, the Company shall use the net proceeds from the sale
of the Securities hereunder for working capital purposes and shall not use such proceeds: (a) for the satisfaction of any portion
of the Company’s debt (other than payment of trade payables in the 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.


 




    	28



    	 



    

 


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.


 


(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.


 




    	29



    	 



    

 


(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.


 


4.12        Participation
in Future Financing.


 


(a)          From
the date hereof until the date that is the 12 month anniversary of the Effective Date, upon any issuance by the Company or any
of its Subsidiaries of Common Stock, Common Stock Equivalents for cash consideration, Indebtedness or a combination of units hereof
(a “Subsequent Financing”), each Purchaser shall have the right to participate in up to an amount of the Subsequent
Financing equal to 100% of the Subsequent Financing (the “Participation Maximum”) on the same terms, conditions
and price provided for in the Subsequent Financing.


 


(b)          Approximately
five (5) Trading Days prior to the closing of the Subsequent Financing, the Company shall deliver to each Purchaser a written notice
of its intention to effect a Subsequent Financing (a “Subsequent Financing Notice”). The Subsequent Financing
Notice shall describe in reasonable detail the proposed terms of such Subsequent Financing, the amount of proceeds intended to
be raised thereunder and the Person or Persons through or with whom such Subsequent Financing is proposed to be effected and shall
include a term sheet or similar document relating thereto as an attachment.


 


(c)          Any
Purchaser desiring to participate in such Subsequent Financing must provide written notice to the Company by not later than 5:30
p.m. (New York City time) on the third (3rd) Trading Day after all of the Purchasers have received the Subsequent Financing Notice
that the Purchaser is willing to participate in the Subsequent Financing, the amount of such Purchaser’s participation, and
representing and warranting that such Purchaser has such funds ready, willing, and available for investment on the terms set forth
in the Subsequent Financing Notice. If the Company receives no such notice from a Purchaser as of such third (3rd) Trading Day,
such Purchaser shall be deemed to have notified the Company that it does not elect to participate.


 


(d)          If
by 5:30 p.m. (New York City time) on the third (3rd ) Trading Day after all of the Purchasers have received the Subsequent
Financing Notice, notifications by the Purchasers of their willingness to participate in the Subsequent Financing (or to cause
their designees to participate) is, in the aggregate, less than the total amount of the Subsequent Financing, then the Company
may effect the remaining portion of such Subsequent Financing on the terms and with the Persons set forth in the Subsequent Financing
Notice.


 




    	30



    	 



    

 


(e)          If
by 5:30 p.m. (New York City time) on the third (3rd) Trading Day after all of the Purchasers have received the Subsequent Financing
Notice, the Company receives responses to a Subsequent Financing Notice from Purchasers seeking to purchase more than the aggregate
amount of the Participation Maximum, each such Purchaser shall have the right to purchase its Pro Rata Portion (as defined below)
of the Participation Maximum.  “Pro Rata Portion” means the ratio of (x) the Subscription Amount of Securities
purchased on the Closing Date by a Purchaser participating under this Section 4.12 and (y) the sum of the aggregate Subscription
Amounts of Securities purchased on the Closing Date by all Purchasers participating under this Section 4.12.


 


(f)          The
Company must provide the Purchasers with a second Subsequent Financing Notice, and the Purchasers will again have the right of
participation set forth above in this Section 4.12, if the Subsequent Financing subject to the initial Subsequent Financing Notice
is not consummated for any reason on the terms set forth in such Subsequent Financing Notice within thirty (30) Trading Days after
the date of the initial Subsequent Financing Notice.


 


(g)          The
Company and each Purchaser agree that if any Purchaser elects to participate in the Subsequent Financing, the transaction documents
related to the Subsequent Financing shall not include any term or provision whereby such Purchaser shall be required to agree
to any restrictions on trading as to any of the Securities purchased hereunder or be required to consent to any amendment to or
termination of, or grant any waiver, release or the like under or in connection with, this Agreement, without the prior written
consent of such Purchaser.


 


(h)          Notwithstanding
anything to the contrary in this Section 4.12 and unless otherwise agreed to by such Purchaser, the Company shall either confirm
in writing to such Purchaser that the transaction with respect to the Subsequent Financing has been abandoned or shall publicly
disclose its intention to issue the securities in the Subsequent Financing, in either case in such a manner such that such Purchaser
will not be in possession of any material, non-public information, by the seventh (7th) Business Day following delivery
of the Subsequent Financing Notice. If by such seventh (7th) Business Day, no public disclosure regarding a transaction
with respect to the Subsequent Financing has been made, and no notice regarding the abandonment of such transaction has been received
by such Purchaser, such transaction shall be deemed to have been abandoned and such Purchaser shall not be deemed to be in possession
of any material, non-public information with respect to the Company or any of its Subsidiaries. 



 


(i)          Notwithstanding
the foregoing, this Section 4.12 shall not apply in respect of an Exempt Issuance.


 


4.13        Subsequent
Equity Sales.


 


(a)          From
the date hereof until the date that is 60 days after the Effective Date of the Resale Registration Statement, 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, however, that the prohibition set forth in this Section 4.13(a)
shall not apply to issuances of Common Stock or Common Stock Equivalents with an effective per share purchase price of at least
$3.04 (subject to adjustment for reverse and forward stock splits and like transactions after the date hereof).


 




    	31



    	 



    

 


(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.


 


(c)          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.


 




    	32



    	 



    

 


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.


 


4.16        Capital
Changes. Until the one year anniversary of the 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.


 


4.17        Transfer
Restrictions.


 


(a)          The
Securities may only be disposed of in compliance with state and federal securities laws. In connection with any transfer of any
Securities other than the Series A-3 Preferred Stock and shares issuable upon conversion thereof, or 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 4.17(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 the Series A-4 Preferred Stock,
the Conversion Shares underlying the Series A-4 Preferred Stock, the Warrants and Warrant Shares issuable upon exercise thereof
in the following form:


 




    	33



    	 



    

 


[NEITHER] THIS
SECURITY [NOR THE SECURITIES INTO WHICH THIS SECURITY IS [CONVERTIBLE] [EXERCISABLE]] 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 AS EVIDENCED BY
A LEGAL OPINION OF COUNSEL TO THE TRANSFEROR TO SUCH EFFECT, THE SUBSTANCE OF WHICH SHALL BE REASONABLY ACCEPTABLE TO THE COMPANY.
THIS SECURITY [AND THE SECURITIES ISSUABLE UPON [CONVERSION] [EXERCISE] 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


 


(c)          Certificates
evidencing (a) the Conversion Shares underlying the Series A-4 Preferred Stock and (b) the Warrant Shares issuable upon exercise
of the Warrants shall not contain any legend (including the legend set forth above): (i) while a registration statement covering
the resale of such security is effective under the Securities Act, (ii) following any sale of such Conversion Shares underlying
the Series A-4 Preferred Stock or Warrant Shares pursuant to Rule 144, (iii) if such Conversion Shares underlying the Series A-4
Preferred Stock or Warrant 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 Conversion Shares underlying the Series A-4 Preferred Stock
or Warrant 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 of the Resale Registration
Statement if required by the Transfer Agent to effect the removal of the legend hereunder. If a Warrant is exercised at a time
when there is an effective registration statement to cover the resale of the Warrant Shares issuable in respect thereof or the
Series A-4 Preferred Stock is converted at a time when there is an effective registration statement to cover the resale of the
Conversion Shares issuable in respect thereof, or if such Warrant Shares may be sold under Rule 144 and the Company is then in
compliance with the current public information required under Rule 144 or such Conversion Shares underlying the Series A-4 Preferred
Stock may be sold under Rule 144 and the Company is then in compliance with the current public information required under Rule
144, or if such Warrant 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 Warrant Shares and without volume or manner-of-sale restrictions
or such Conversion Shares underlying the Series A-4 Preferred Stock 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 Conversion 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 Conversion Shares underlying
the Series A-4 Preferred Stock and Warrant 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 4.17(c), it will, no later than three Trading Days
following the delivery by a Purchaser to the Company or the Transfer Agent of a certificate representing Conversion Shares underlying
the Series A-4 Preferred Stock or Warrant 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. 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 such Conversion Shares
underlying the Series A-4 Preferred Stock or Warrant 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.


 




    	34



    	 



    

 


(d)          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, for each $1,000 of Conversion Shares underlying the Series A-4 Preferred Stock or Warrant 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 4.16(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. Nothing herein shall limit such Purchaser’s right to pursue actual damages for the Company’s failure
to deliver certificates representing any Securities as required by the Transaction Documents, 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.


 


(e)          Each
Purchaser, severally and not jointly with the other Purchasers, agrees with the Company that such Purchaser will sell any restricted
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 4.17 is predicated upon the Company’s reliance upon this
understanding.

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 Closing
has not been consummated on or before July 1, 2014; 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, the Prospectus and the Prospectus Supplement,
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.


 


5.4           Notices.
Any and all notices or other communications or deliveries required or permitted to be provided hereunder shall be in writing and
shall be deemed given and effective on the earliest of: (a) the date of transmission, if such notice or communication is delivered
via facsimile at the facsimile number set forth on the signature pages attached hereto at or prior to 5:30 p.m. (New York City
time) on a Trading Day, (b) the next Trading Day after the date of transmission, if such notice or communication is delivered via

required to be given. The address for such notices and communications shall be as set forth on the signature pages attached hereto.


 


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.


 




    	36



    	 



    

 


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.”


 


5.8           No
Third-Party Beneficiaries. 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.


 


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 Closing and the delivery of the Securities.


 




    	37



    	 



    

 


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.


 


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.


 




    	38



    	 



    

 


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]


 


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. 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.


 




    	39



    	 



    

 


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.
