enforceable and there is no existing infringement by another Person of any of the Intellectual Property Rights, except as could
not have or reasonably be expected to not have a Material Adverse Effect. The Company and its Subsidiaries have taken reasonable

all applicable requirements of the Sarbanes-Oxley Act of 2002 that are effective as of the date hereof, and any and all applicable

order to render inapplicable any control share acquisition, business combination, poison pill (including any distribution under
a rights agreement) or other similar anti-takeover provision under the Company’s certificate of incorporation (or similar
charter documents) or the laws of its state of incorporation that is or could become applicable to the Purchasers as a result
of the Purchasers and the Company fulfilling their obligations or exercising their rights under the Transaction Documents, including
without limitation as a result of the Company’s issuance of the Securities and the Purchasers’ ownership of the Securities.

 

(z)
Disclosure. Except with respect to the material terms and conditions of the transactions contemplated by the Transaction
Documents, 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

fact necessary in order to make the statements made therein, in light of the circumstances under which they were made, not misleading.
The press releases disseminated by the Company during the twelve months preceding the date of this Agreement taken as a whole
do not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary
in order to make the statements therein, in light of the circumstances under which they were made and when made, not misleading.
The Company acknowledges and agrees that no Purchaser makes or has made any representations or warranties with respect to the
transactions contemplated hereby other than those specifically set forth in Section 3.2 hereof.

No Integrated Offering. Assuming the accuracy of the Purchasers’ representations and warranties set forth in Section
3.2, 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 (i) the Securities Act which would
require the registration of any such securities under the Securities Act, or (ii) any applicable shareholder approval provisions
of any Trading Market on which any of the securities of the Company are listed or designated.

the bankruptcy or reorganization laws of any jurisdiction within one year from the applicable Closing Date. Schedule 3.1(bb)
and the SEC Reports sets forth as of the date hereof all outstanding secured and unsecured Indebtedness of the Company or
any Subsidiary, or for which the Company or any Subsidiary has commitments. For the purposes of this Agreement, “Indebtedness”
means (x) any liabilities for borrowed money or amounts owed in excess of $150,000 (other than trade accounts payable incurred

ordinary course of business; and (z) the present value of any lease payments in excess of $150,000 due under leases required to

the Company or of any Subsidiary know of no basis for any such claim.

or otherwise, other than indebtedness secured by purchase money security interests (which is senior only as to underlying assets
covered thereby) and capital lease obligations (which is senior only as to the property covered thereby).

Acknowledgment Regarding Purchasers’ Purchase of Securities. The Company acknowledges and agrees that each of the
Purchasers is acting solely in the capacity of an arm’s length purchaser with respect to the Transaction Documents and the
transactions contemplated thereby. The Company further acknowledges that no Purchaser is acting as a financial advisor or fiduciary
of the Company (or in any similar capacity) with respect to the Transaction Documents and the transactions contemplated thereby
and any advice given by any Purchaser or any of their respective representatives or agents in connection with the Transaction
Documents and the transactions contemplated thereby is merely incidental to the Purchasers’ purchase of the Securities.

Transaction Documents has been based solely on the independent evaluation of the transactions contemplated hereby by the Company
and its representatives.

Acknowledgment Regarding Purchaser’s Trading Activity. Anything in this Agreement
or elsewhere herein to the contrary notwithstanding (except for Sections 3.2(f) and 4.15 hereof), it is understood and acknowledged
by the Company that: (i) none of the Purchasers has been asked by the Company to agree, nor has any Purchaser agreed, to desist
from purchasing or selling, long and/or short, securities of the Company, or “derivative” securities based on securities
issued by the Company or to hold the Securities for any specified term, (ii) past or future open market or other transactions
by any Purchaser, specifically including, without limitation, Short Sales or “derivative” transactions, before or
after the closing of this or future private placement transactions, may negatively impact the market price of the Company’s
publicly-traded securities, (iii) any Purchaser, and counter-parties in “derivative” transactions to which any such
Purchaser is a party, directly or indirectly, may presently have a “short” position in the Common Stock and (iv) each
Purchaser shall not be deemed to have any affiliation with or control over any arm’s length counter-party in any “derivative”
transaction. The Company further understands and acknowledges that (y) one or more Purchasers may engage in hedging activities
at various times during the period that the Securities are outstanding, including, without limitation, during the periods that
the value of the Warrant Shares deliverable with respect to Securities are being determined, and (z) such hedging activities (if
any) could reduce the value of the existing stockholders’ equity interests in the Company at and after the time that the
hedging activities are being conducted. The Company acknowledges that such aforementioned hedging activities do not constitute
a breach of any of the Transaction Documents.

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 each Closing Date to the Company as follows (unless as of a specific date therein,
in which case they shall be accurate as of such date):

 

(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

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. The Purchaser’s execution, delivery
and performance of this Agreement and the other Transaction Documents and the consummation by it of the transactions contemplated
hereby do not and will not (i) conflict with or violate any provision of the Purchaser’s certificate or articles of incorporation,
bylaws or other organizational or charter documents, or (ii) conflict with or result in a violation of any law, rule, regulation,
order, judgment, injunction, decree or other restriction of any court or governmental authority to which the Purchaser is subject
(including federal and state securities laws and regulations), or by which any property or asset of the Purchaser is bound or
affected.

 

(b)
Own Account. Such Purchaser understands that the Securities are “restricted securities” and have not been registered
under the Securities Act or any applicable state securities law and is acquiring the 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 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.

 

(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 Debentures it will be an “accredited investor” as defined
in Rule 501 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
understands that nothing in the Transaction Documents or any other materials presented to such Purchaser in connection with the
purchase and sale of the Shares constitutes legal, tax or investment advice.

 

(e)
General Solicitation. Such Purchaser is not, to such Purchaser’s knowledge, 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, to the knowledge of such Purchaser, any other
general solicitation or general advertisement.

 

(f)
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

with this Agreement or the consummation of the transactions contemplated hereby. Notwithstanding the foregoing, for the avoidance

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.

 

    	 	27	 

    	 

    

 

(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.

 

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.

 

    	 	28	 

    	 

    

 

(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 (assuming cashless exercise of the
Warrants), (iii) if such Underlying Shares are eligible for sale under Rule 144 (assuming cashless exercise of the Warrants),
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 or the Purchaser promptly after the Effective Date if required by the Transfer Agent to effect the removal of the
legend hereunder, or if requested by a Purchaser, respectively. If all or any portion of a Warrant is exercised or Debenture is
converted 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 without the requirement for the Company to be in compliance with the current public
information required under Rule 144 (assuming cashless exercise of the Warrants) 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 two Trading Days 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 second
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 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.

 

(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 seventh Trading Day following 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 (A) such number of Underlying Shares that the Company was required to deliver to
such Purchaser by the Legend Removal Date multiplied by (B) the lowest closing sale price of the Common Stock on any Trading Day
during the period commencing on the date of the 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).

 

    	 	29	 

    	 

    

 

(e)
Each Purchaser, severally and not jointly with the other Purchasers, agrees with the Company that such Purchaser will sell 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

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 (i) shall fail for any reason to satisfy the current public information
requirement under Rule 144(c) or (ii) has ever been an issuer described in Rule 144 (i)(1)(i) or becomes an issuer in the future,
and the Company shall fail to satisfy any condition set forth in Rule 144(i)(2) (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 such Purchaser’s aggregate Subscription Amount of such Purchaser’s Securities
then held 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.

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
Exercise Procedures. 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 Debentures set forth the totality of the procedures required of
the Purchasers in order to exercise the Warrants or convert the Debentures. 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 Debentures. No additional legal opinion, other information or instructions shall be required of the Purchasers to exercise
their Warrants or convert their Debentures. The Company shall honor exercises of the Warrants and conversions of the Debentures

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

Minimum on such date, 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.

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)

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 the Transaction Documents unless the
same consideration is also offered to all of the parties to such Transaction Documents. Further, the Company shall not make any
payment of principal or interest on the Debentures in amounts which are disproportionate to the respective principal amounts outstanding
on the Debentures at any applicable time. 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 or duty not to trade in the securities of the Company
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.

 

    	 	35	 

    	 

    

 

4.16
Form D; Blue Sky Filings. The Company agrees to timely file a Form D with respect to the Securities as required under Regulation
D and to provide a copy thereof, promptly upon request of any Purchaser. The Company shall take such action as the Company shall
reasonably determine is necessary in order to obtain an exemption for, or to qualify the Securities for, sale to the Purchasers
at each Closing under applicable securities or “Blue Sky” laws of the states of the United States, and shall provide
evidence of such actions promptly upon request of any Purchaser.

 

4.17
Capital Changes. Except as may be required to maintain the listing of the Common Stock on a national stock exchange, until
the one year anniversary of the Effective 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 at least a majority in principal amount outstanding
of the Debentures.

 

4.18
Security Agreement Acknowledgement. The Company hereby acknowledges and agrees that (a) the security interests granted
to the holders of the Existing Debentures pursuant to the Security Agreement applies to and covers the obligations of the Company
to the Purchasers evidenced by the Debentures and (b) the Debentures rank first in priority to all other Indebtedness of the Company;
provided, however, Debentures issued in exchange for the Existing Debentures hereunder shall have seniority over
the Debentures issued for cash-consideration on the date hereof, which Debentures issued for cash-consideration on the date hereof
shall be junior in liquidation to the Debentures received in exchange for the Exchange Debentures. Additionally, the Debenture
constitutes an “Obligation” under the Subsidiary Guarantee as if the Debentures were Additional Debentures issued
pursuant to the Purchase Agreement. Each Purchaser that is a party to the Security Agreement hereby consents and agrees to permit
the novation to the Security Agreement of any Purchaser’s hereunder that are not parties to the Security Agreement on the
date hereof.

 

4.19
Amendment to Exercise Price of Existing Warrants. The Company and each Purchaser hereby agree to amend the “Exercise
Price” of the Warrant to equal $6.00, subject to adjustment thereunder and to delete the following provision in Section
3(e) of the Warrant which shall no longer be of any force or effect: “Notwithstanding anything to the contrary, in the
event of a Fundamental Transaction, the Company or any Successor Entity (as defined below) shall, at the Holder’s option,
exercisable at any time concurrently with, or within 30 days after, the consummation of the Fundamental Transaction (or, if later,
the date of the public announcement of the applicable Fundamental Transaction), purchase this Warrant from the Holder by paying
to the Holder an amount of cash equal to the Black Scholes Value of the remaining unexercised portion of this Warrant on the date
of the consummation of such Fundamental Transaction. “Black Scholes Value” means the value of this Warrant
based on the Black and Scholes Option Pricing Model obtained from the “OV” function on Bloomberg, L.P. (“Bloomberg”)
determined as of the day of consummation of the applicable Fundamental Transaction for pricing purposes and reflecting (A) a risk-free
interest rate corresponding to the U.S. Treasury rate for a period equal to the time between the date of the public announcement
of the applicable Fundamental Transaction and the Termination Date, (B) an expected volatility equal to the greater of 100% and
the 100 day volatility obtained from the HVT function on Bloomberg as of the Trading Day immediately following the public announcement
of the applicable Fundamental Transaction, (C) the underlying price per share used in such calculation shall be the sum of the
price per share being offered in cash, if any, plus the value of any non-cash consideration, if any, being offered in such Fundamental
Transaction and (D) a remaining option time equal to the time between the date of the public announcement of the applicable Fundamental
Transaction and the Termination Date. The payment of the Black Scholes Value will be made by wire transfer of immediately available
funds within five Business Days of the Holder’s election (or, if later, on the effective date of the Fundamental Transaction).”
This amendment shall be effective immediately upon the execution of this Agreement. At the request of a holder of the Existing
Warrant, the Company shall deliver a restated and amended Existing Warrant certificate reflecting these amendments within 3 Trading
Days of such request.

Consents and Waivers of Purchasers. The Company acknowledge and agrees that the following Events of Default exist or will
exist under the Existing Debentures and Debentures:

 

(a)
The Company was late filing its Annual Report on Form 10-K for the year ended June 30, 2018 of the Company (the “2018
Annual Report”) expects that it will be late in filing its Annual Report on Form 10-K for the year ended June 30, 2019
(the “2019 Annual Report”) and its Quarterly Report on Form 10-Q for the quarter ended September 30, 2019 (the
“Q1 Quarterly Report”). Each Purchaser, severally and not jointly with the other Purchasers, hereby waives
the Event of Default resulting from the failure to timely file the 2018 Annual Report by Company and the Events of Default that
will result from the failure to timely file the 2019 Annual Report and the Q1 Quarterly Report by the Company, and agrees not
to exercise any of the rights and remedies available to the Holder as a result of such Event of Defaults; provided, however,
the Company shall be current in its periodic filings with the Commission on or before March 31, 2020 and the failure to become
current by such date shall be deemed an Event of Default under the Debentures.

 

(b)
The Company failed to make an interest payment under the Existing Debenture which was due on July 1, 2019 (the “July
2019 Interest Payment”), an interest payment due on October 1, 2019 (the “October 2019 Interest Payment”)
and expect to fail to make the interest payment on January 1, 2020 (the “January 2020 Interest Payment”), which
failures constitute Events of Default under the Existing Debentures. Each Purchaser, severally and not jointly with the other
Purchasers, hereby waives the Event of Default resulting from the failure by the Company to make the July 2019 Interest Payment
and the Event of Default resulting from the failure by the Company to make the October 2019 Interest Payment and the Event of
Default that will result from the Company’s failure to make the January 2020 Interest Payment, and agrees not to exercise
any of the rights and remedies available to the Holder as a result of such Event of Defaults. In lieu of cash payment of the July
2019 Interest Payment, October 2019 Interest Payment and January 2020 Interest Payment, at the election of the Holder, such amounts
shall be either (i) issued in shares of Common Stock at a price of $_____, which is the average of the VWAPs for the 10 consecutive
Trading Days as of the most recent Trading Day that is immediately prior to the date hereof or (ii) added to the principal amount
of the Debentures issued hereunder.

 

    	 	37	 

    	 

    

 

(c)
The Company is entering into the Merger Agreement pursuant to which SES Merger Sub, Inc., a Delaware corporation and a wholly-owned
subsidiary of the Company (“Merger Sub”) will merge with and into Australian Future Energy PTY LTD, an Australian
proprietary limited company (“AFE”), upon the terms and subject to the conditions of the Merger Agreement (the
“Merger”). Upon the consummation of the Merger, the Merger Sub will cease to exist, and AFE will continue as
a wholly-owned subsidiary of the Company. At the closing of the Merger, the Company will issue to the shareholders of AFE 3,875,000
shares of Common Stock. The Merger constitutes a “Fundamental Transaction” as defined in the Existing Debentures and
Debentures and the Existing Debentures and Debentures require the repayment in full of the principal and interest under the Existing
Debentures and Debentures. Each Purchaser, severally and not jointly with the other Purchasers, hereby consents and agrees that,
notwithstanding any limitations in the Existing Debentures or Debentures to the contrary, the Company is permitted to consummate
the Merger without repaying the Existing Debenture or Debentures in full.

 

(d)
In order to cover operating expenses and the expenses of the Company and AFE associated with the Merger, the Company is entering
into this Agreement which provides for the issuance of Debentures and Warrants for additional cash Subscription Amounts, provided
that the Debentures issued for cash Subscription Amounts shall be junior in priority to the Debentures issued in exchange for
the Exchange Debentures (“Interim Funding”). Each Purchaser, severally and not jointly with the other Purchasers,
hereby consents and agrees that, notwithstanding any limitations in the Existing Debentures or Debenture to the contrary, the
Company is permitted to consummate the Interim Funding and issue the Debentures and Warrants hereunder.

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 October 31, 2019; provided, however, that such
termination will not affect the right of any party to sue for any breach by any other party (or parties). The Purchaser shall
have the right to terminate any of its obligations of each of the Second and Third Closings, as applicable, if the Second Closing
has not occurred on or before February 28, 2020 and the Third Closing has not occurred on or before May 31, 2020.

 

5.2
Fees and Expenses. At the First Closing, the Company has agreed to reimburse the Placement Agent the non-accountable sum
of $30,000 for its legal 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

5.3
Entire Agreement. The Transaction Documents, together with the exhibits and schedules thereto, contain the entire understanding

or written, with respect to such matters, which the parties acknowledge have been merged into such documents, exhibits and schedules.

 

5.4

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 Purchasers holding at least 50.1% in interest of the Debentures
then outstanding or, in the case of a waiver, by the party against whom enforcement of any such waived provision is sought, provided
that if any amendment, modification or waiver disproportionately and adversely impacts a Purchaser (or group of Purchasers), the
consent of such disproportionately impacted Purchaser (or group of Purchasers) shall also be required. 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. Any proposed amendment
or waiver that disproportionately, materially and adversely affects the rights and obligations of any Purchaser relative to the
comparable rights and obligations of the other Purchasers shall require the prior written consent of such adversely affected Purchaser,
Any amendment effected in accordance with accordance with this Section 5.5 shall be binding upon each Purchaser and holder of
Securities and the Company.

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

5.8
No Third Party Beneficiaries. The Placement Agent shall be the third party beneficiary of the representations and warranties
of the Company in Section 3.1 and the representations and warranties of the Purchasers in Section 3.2. 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

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

5.10
Survival. The representations and warranties contained herein shall survive each 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.

 

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 exercise of a Warrant, the applicable Purchaser shall be required to return any shares of
Common Stock subject to any such rescinded 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.

 

    	 	41	 

    	 

    

 

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
Usury. To the extent it may lawfully do so, the Company hereby agrees not to insist upon or plead or in any manner whatsoever
claim, and will resist any and all efforts to be compelled to take the benefit or advantage of, usury laws wherever enacted, now
or at any time hereafter in force, in connection with any Action or Proceeding that may be brought by any Purchaser in order to
enforce any right or remedy under any Transaction Document. Notwithstanding any provision to the contrary contained in any Transaction
Document, it is expressly agreed and provided that the total liability of the Company under the Transaction Documents for payments
in the nature of interest shall not exceed the maximum lawful rate authorized under applicable law (the “Maximum Rate”),
and, without limiting the foregoing, in no event shall any rate of interest or default interest, or both of them, when aggregated
with any other sums in the nature of interest that the Company may be obligated to pay under the Transaction Documents exceed
such Maximum Rate. It is agreed that if the maximum contract rate of interest allowed by law and applicable to the Transaction
Documents is increased or decreased by statute or any official governmental action subsequent to the date hereof, the new maximum
contract rate of interest allowed by law will be the Maximum Rate applicable to the Transaction Documents from the effective date
thereof forward, unless such application is precluded by applicable law. If under any circumstances whatsoever, interest in excess
of the Maximum Rate is paid by the Company to any Purchaser with respect to indebtedness evidenced by the Transaction Documents,
such excess shall be applied by such Purchaser to the unpaid principal balance of any such indebtedness or be refunded to the
Company, the manner of handling such excess to be at such Purchaser’s election.

 

    	 	42	 

    	 

    

 

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. It is expressly understood that each provision contained in this Agreement and in each other Transaction Document
is between the Company and a Purchaser, solely, and not between the Company and the Purchasers collectively and not between and
among 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.
