A.The
Company and each Buyer are executing and delivering this Agreement in reliance upon the exemption from securities registration
afforded by Section 4(a)(2) of the Securities Act of 1933, as amended (the “1933 Act”), and Rule 506(b) of

stock, par value $0.0001 per share (the “Common Stock”) (the shares of Common Stock issuable pursuant to the

Schedule A (which aggregate principal amount of Notes for all Buyers shall be $1,500,000), and (ii) Warrants, in substantially
the form attached hereto as Exhibit B (the “Warrants”), representing the right to acquire that number

NOW,
THEREFORE, the Company and each Buyer hereby agree as follows:


 


1.PURCHASE
AND SALE OF NOTES AND WARRANTS.


 


(a)Purchase
of Notes and Warrants. Subject to the satisfaction (or waiver) of the conditions set forth in Sections 6 and 7 below, the
Company shall issue and sell to each Buyer, and each Buyer severally, but not jointly, agrees to purchase from the Company on
the Closing Date (as defined below), (x) a Note in the principal amount as is set forth opposite such Buyer’s name in column
(3) on the Schedule of Buyers and (y) a Warrant to acquire up to that number of Warrant Shares as is set forth opposite such Buyer’s
name in column (4) on the Schedule of Buyers.


 


(b)Closing.
The date and time of the closing (the “Closing”) shall be 10:00 a.m., New York City time, on the date hereof

(c)Purchase
Price. The aggregate purchase price for the Notes and the Warrants to be purchased by each Buyer at the Closing (the “Purchase

Buyer shall pay $1,000 for each $1,000 of principal amount of Notes and related Warrants to be purchased by such Buyer at the
Closing. The Buyers and the Company agree that the Notes and the Warrants constitute an “investment unit” for purposes
of Section 1273(c)(2) of the Internal Revenue Code of 1986, as amended (the “Code”). The Buyers and the Company
mutually agree that the allocation of the issue price of such investment unit between the Notes and the Warrants in accordance
with Section 1273(c)(2) of the Code and Treasury Regulation Section 1.1273-2(h) shall be $49.30 per $1,000 of Purchase Price to
be allocated to the Warrants and the balance of each $1,000 of Purchase Price to be allocated to the Notes, and neither the Buyers
nor the Company shall take any position inconsistent with such allocation in any tax return or in any judicial or administrative
proceeding in respect of taxes.


 


(d)Form
of Payment. On the Closing Date, (i) each Buyer shall pay its Purchase Price to the Company for the Notes and the Warrants
to be issued and sold to such Buyer at the Closing by wire transfer of immediately available funds in accordance with the Company’s
written wire instructions and (ii) the Company shall deliver to each Buyer the Notes (allocated in the principal amounts as such
Buyer shall request) which such Buyer is then purchasing hereunder along with the Warrants (allocated in the amounts as such Buyer
shall request) which such Buyer is purchasing hereunder, in each case duly executed on behalf of the Company and registered in
the Company record in the name of such Buyer or its designee.


 


2.BUYER’S
REPRESENTATIONS AND WARRANTIES. Each Buyer, severally and not jointly, represents and warrants with respect to only itself
that:


 


(a)No
Public Sale or Distribution. Such Buyer (i) is acquiring the Notes and the Warrants, (ii) upon issuance of the Conversion
Shares pursuant to the terms of the Notes and upon exercise of the Warrants will acquire the Conversion Shares and the Warrant
Shares, respectively, and (iii) upon issuance of the Additional Warrants, if any, pursuant to the terms of this Agreement and
upon exercise of such Additional Warrants, if any, will acquire the Additional Warrant Shares issuable upon exercise of such Additional
Warrants, if any, for its own account and not with a view towards, or for resale in connection with, the public sale or distribution
thereof, except pursuant to sales registered or exempted under the 1933 Act; provided, however, that by making the
representations herein, such Buyer does not agree to hold any of the Securities for any minimum or other specific term and reserves
the right to dispose of the Securities at any time in accordance with or pursuant to a registration statement or an exemption
under the 1933 Act. Such Buyer is acquiring the Securities hereunder in the ordinary course of its business. Such Buyer does not
presently have any agreement or understanding, directly or indirectly, with any Person (as defined below) to distribute any of
the Securities. For purposes of this Agreement, “Person” means an individual, a limited liability company,
a partnership, a joint venture, a corporation, a trust, an unincorporated organization and a government or any department or agency
thereof.

(b)Accredited
Investor Status. Such Buyer is an “accredited investor” as that term is defined in Rule 501(a) of Regulation D.
Such Buyer has executed and delivered to the Company a questionnaire (the “Investor Questionnaire”), substantially
in the form attached hereto as Exhibit D, which such Buyer represents and warrants is true, correct and complete.


 


(c)Reliance
on Exemptions. Such Buyer understands that the Securities are being offered and sold to it in reliance on specific exemptions
from the registration requirements of United States federal and state securities laws and that the Company is relying in part
upon the truth and accuracy of, and such Buyer’s compliance with, the representations, warranties, agreements, acknowledgments
and understandings of such Buyer set forth herein in order to determine the availability of such exemptions and the eligibility
of such Buyer to acquire the Securities.


 


(d)Information.
Such Buyer and its advisors, if any, have been furnished with all materials relating to the business, finances and operations
of the Company and materials relating to the offer and sale of the Securities that have been requested by such Buyer. Such Buyer
and its advisors, if any, have been afforded the opportunity to ask questions of the Company. Neither such inquiries nor any other
due diligence investigations conducted by such Buyer or its advisors, if any, or its representatives shall modify, amend or affect
such Buyer’s right to rely on the Company’s representations and warranties contained herein. Such Buyer understands
that its investment in the Securities involves a high degree of risk and is able to afford a complete loss of such investment.
Such Buyer has sought such accounting, legal and tax advice as it has considered necessary to make an informed investment decision
with respect to its acquisition of the Securities. Such Buyer confirms and agrees that (i) it has independently evaluated the
investment risks and the merits of its decision to purchase the Securities, (ii) it has not relied on the advice of, or any representations
by, any other Person, other than the Company and its officers and directors, in making such decision, and (iii) no Person, other
than the Company and its officers and directors, has any responsibility with respect to the completeness or accuracy of any information
or materials furnished to such Buyer in connection with the transactions contemplated hereby.


 


(e)No
Governmental Review. Such Buyer understands that no United States federal or state agency or any other government or governmental
agency has passed on or made any recommendation or endorsement of the Securities or the fairness or suitability of the investment
in the Securities nor have such authorities passed upon or endorsed the merits of the offering of the Securities.


 


(f)Transfer
or Resale. Such Buyer understands that except as provided in Section  4 (q) (i) the Securities have not been and are not being
registered under the 1933 Act or any state securities laws, and may not be offered for sale, sold, assigned or transferred unless
(A) subsequently registered thereunder, (B) such Buyer shall have delivered to the Company an opinion of counsel, in form and
substance reasonably acceptable to the Company, to the effect that such Securities to be sold, assigned or transferred may be
sold, assigned or transferred pursuant to an exemption from such registration, or (C) such Buyer provides the Company with reasonable
assurance that such Securities can be sold, assigned or transferred pursuant to Rule 144 promulgated under the 1933 Act (“Rule
144”) or Rule 144A promulgated under the 1933 Act (“Rule 144A”) (or successor rules thereto) (collectively,
“Resale Exemptions”); (ii) any sale of the Securities made in reliance on the Resale Exemptions may be made
only in accordance with the terms of Rule 144 or Rule 144A, as applicable, and further, if a Resale Exemption is not applicable,
any resale of the Securities under circumstances in which the seller (or the Person) through whom the sale is made) may be deemed
to be an underwriter (as that term is defined in the 1933 Act) may require compliance with some other exemption under the 1933
Act or the rules and regulations of the SEC thereunder; and (iii) neither the Company nor any other Person is under any obligation
to register the Securities under the 1933 Act or any state securities laws or to comply with the terms and conditions of any exemption
thereunder. Notwithstanding the foregoing, the Securities may be pledged in connection with a bona fide margin account or other
loan or financing arrangement secured by the Securities and such pledge of Securities shall not be deemed to be a transfer, sale
or assignment of the Securities hereunder, and no Buyer effecting a pledge of Securities shall be required to provide the Company
with any notice thereof or otherwise make any delivery to the Company pursuant to this Agreement or any other Transaction Document
(as defined in Section  3 (b)), including, without limitation, this Section  2 (f).


 


(g)Legends.


 


(i)Such
Buyer understands that the certificates or other instruments representing the Notes, the Warrants and the Additional Warrants,
if any, and, until such time as the resale of the Conversion Shares, the Warrant Shares and the Additional Warrant Shares, if
any, have been registered under the 1933 Act, the stock certificates representing the Conversion Shares, the Warrant Shares and
the Additional Warrant Shares, if any, except as set forth below, shall bear any legend as required by the “blue sky”
laws of any state and a restrictive legend in substantially the following form (and a stop-transfer order may be placed against
transfer of such stock certificates or other instruments):


 


[NEITHER
THE ISSUANCE AND SALE OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE NOR THE SECURITIES INTO WHICH THESE SECURITIES [MAY
BE CONVERTIBLE] [ARE EXERCISABLE] HAVE BEEN][THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT
BEEN] REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY
NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED (I) IN THE ABSENCE OF (A) AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES
UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR (B) AN OPINION OF COUNSEL, IN FORM AND SUBSTANCE REASONABLY ACCEPTABLE TO THE
COMPANY, THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT OR (II) UNLESS SOLD PURSUANT TO RULE 144 OR RULE 144A UNDER SAID ACT.

    	 	- 3 -	 



    


    


  


The
legend set forth above shall be removed and the Company shall issue a certificate or other instrument without such legend to the
holder of the Securities upon which it is stamped or issue to such holder by electronic delivery at the applicable balance account
at The Depository Trust Company (“DTC”), if, unless otherwise required by state securities laws, (i) such
Securities are registered for resale under the 1933 Act (in which case an alternate prospectus delivery legend may apply), (ii)
in connection with a sale, assignment or other transfer, such holder provides the Company with an opinion of counsel, in form
and substance reasonably acceptable to the Company, to the effect that such sale, assignment or transfer of the Securities may
be made without registration under the applicable requirements of the 1933 Act, or (iii) the Securities can be sold, assigned
or transferred pursuant to Rule 144 or Rule 144A. The Company shall be responsible for the fees of its transfer agent and all
DTC fees associated with such issuance.


 


(ii)Such
Buyer understands that the certificates or other instruments representing the Notes, the Warrants and the Additional Warrants,
if any, shall also bear the legend required by the Subordination Agreement, until such time as the Subordination Agreement is
no longer applicable to the Notes, the Warrants and the Additional Warrants, if any.


 


(h)Validity;
Enforcement. This Agreement has been duly and validly authorized, executed and delivered on behalf of such Buyer and shall
constitute the legal, valid and binding obligations of such Buyer enforceable against such Buyer in accordance with their respective
terms, except as such enforceability may be limited by general principles of equity or to applicable bankruptcy, insolvency, reorganization,
moratorium, liquidation and other similar laws relating to, or affecting generally, the enforcement of applicable creditors’
rights and remedies.


 


(i)No
Conflicts. The execution, delivery and performance by such Buyer of this Agreement and the consummation by such Buyer of the
transactions contemplated hereby and thereby will not (i) result in a violation of the organizational documents of such Buyer
or (ii) conflict with, or constitute a default (or an event which with notice or lapse of time or both would become a default)
under, or give to others any rights of termination, amendment, acceleration or cancellation of, any agreement, indenture or instrument
to which such Buyer is a party, or (iii) result in a violation of any law, rule, regulation, order, judgment or decree (including
federal and state securities laws) applicable to such Buyer, except in the case of clauses (ii) and (iii) above, for such conflicts,
defaults, rights or violations which would not, individually or in the aggregate, reasonably be expected to have a material adverse
effect on the ability of such Buyer to perform its obligations hereunder.


 


(j)Short
Sales. Between the time such Buyer learned about the offering contemplated by this Agreement and the public announcement of
the offering, such Buyer has not engaged in any short sales or similar transactions with respect to the Common Stock, nor has
such Buyer, directly or indirectly, caused any Person to engage in any short sales or similar transactions with respect to the
Common Stock. Such Buyer shall not engage in any short sales involving the Securities in violation of the 1933 Act. Notwithstanding
the foregoing, in the case of a Buyer that is a multi-managed investment vehicle whereby separate portfolio managers manage separate
portions of such Buyer’s assets and the portfolio managers have no direct knowledge of the investment decisions made by
the portfolio managers managing other portions of such Buyer’s assets, the representation set forth above shall apply only
with respect to the portion of assets managed by the portfolio managers that have knowledge about the financing transaction contemplated
by this Agreement.

3.REPRESENTATIONS
AND WARRANTIES OF THE COMPANY.


 


The
Company represents and warrants, as of the Closing Date (unless otherwise provided herein), to each of the Buyers that:


 


(a)Organization
and Qualification. Each of the Company and its “Subsidiaries” (which for purposes of this Agreement means
any entity in which the Company, directly or indirectly, owns any of the capital stock or holds an equity or similar interest)
are entities duly organized and validly existing in good standing under the laws of the jurisdiction in which they are formed,
and have the requisite power and authorization to own their properties and to carry on their business as now being conducted.
Each of the Company and its Subsidiaries is duly qualified as a foreign entity to do business and is in good standing in every
jurisdiction in which its ownership of property or the nature of the business conducted by it makes such qualification necessary,
except to the extent that the failure to be so qualified or be in good standing would not reasonably be expected to have a Material
Adverse Effect. As used in this Agreement, “Material Adverse Effect” means any material adverse effect on the
business, properties, assets, operations, results of operations, condition (financial or otherwise) or prospects of the Company
and its Subsidiaries, taken as a whole, or on the transactions contemplated hereby or on the other Transaction Documents or by
the agreements and instruments to be entered into in connection herewith or therewith, or on the authority or ability of the Company
to perform its obligations under the Transaction Documents. The Company has no Subsidiaries except as set forth on Schedule
 3 (a).

Agreement, the Notes, the Warrants, the Irrevocable Transfer Agent Instructions (as defined in Section  5 (b)), the Subordination
Agreement and each of the other agreements entered into by the parties hereto in connection with the transactions contemplated
by this Agreement (collectively, the “Transaction Documents”) and to issue the Securities in accordance with
the terms hereof and thereof. The execution and delivery of the Transaction Documents by the Company and the consummation by the
Company of the transactions contemplated hereby and thereby, including, without limitation, the issuance of the Notes, the Warrants
and the Additional Warrants, if any, and the reservation for issuance and the issuance of the Conversion Shares,the Warrant Shares
and the Additional Warrant Shares, if any, have been duly authorized by the Company’s Board of Directors and (other than
filings as may be required by state securities agencies) no further filing, consent, or authorization is required by the Company,
its Board of Directors or its stockholders. This Agreement and the other Transaction Documents have been duly executed and delivered
by the Company, and constitute the legal, valid and binding obligations of the Company, enforceable against the Company in accordance
with their respective terms, except as such enforceability may be limited by general principles of equity or applicable bankruptcy,
insolvency, reorganization, moratorium, liquidation or similar laws relating to, or affecting generally, the enforcement of applicable
creditors’ rights and remedies.


 






    	 	- 5 -	 



    


    

 


(c)Issuance
of Securities. The issuance of the Notes, the Warrants and the Additional Warrants, subject to the conditions set forth in
Section 4(r), are duly authorized and, upon issuance, shall be validly issued free from all preemptive or similar rights, taxes,
liens and charges with respect to the issue thereof. Assuming the accuracy of each of the representations and warranties set forth
in Section 2 of this Agreement, the offer and issuance by the Company of the Securities is exempt from registration under the
1933 Act.


 


(d)No
Conflicts. The execution, delivery and performance of the Transaction Documents by the Company and the consummation by the
Company of the transactions contemplated hereby and thereby (including, without limitation, the issuance of the Notes, the Warrants
and the Additional Warrants, if any, and reservation for issuance and issuance of the Conversion Shares, the Warrant Shares and
the Additional Warrant Shares) will not (i) result in a violation of the Certificate of Incorporation (as defined in Section 3(p))
or Bylaws (as defined in Section 3(p)), any memorandum of association, certificate of incorporation, certificate of formation,
bylaws, any certificate of designations or other constituent documents of the Company or any of its Subsidiaries, any capital
stock of the Company or any of its Subsidiaries or the articles of association or bylaws of the Company or any of its Subsidiaries
or (ii) conflict with, or constitute a default (or an event which with notice or lapse of time or both would become a default)
in any respect under, or give to others any rights of termination, amendment, acceleration or cancellation of, any material agreement,
indenture or instrument to which the Company or any of its Subsidiaries is a party, or (iii) result in a violation of any
law, rule, regulation, order, judgment or decree (including other foreign, federal and state securities laws and regulations and
the rules and regulations of the OTCQB (the “Principal Market”) and including all applicable laws of the State
of Delaware and any foreign, federal and state laws, rules and regulations) applicable to the Company or any of its Subsidiaries
or by which any property or asset of the Company or any of its Subsidiaries is bound or affected.


 


(e)Consents.

or registration with, any court, governmental agency or any regulatory or self-regulatory agency or any other Person in order
for it to execute, deliver or perform any of its obligations under or contemplated by the Transaction Documents, in each case
in accordance with the terms hereof or thereof. The Company is not in violation of the requirements of the Principal Market and
has no knowledge of any facts that would reasonably lead to delisting or suspension of the Common Stock in the foreseeable future.
The issuance by the Company of the Securities shall not have the effect of delisting or suspending the Common Stock from the Principal
Market.


 


(f)Acknowledgment
Regarding Buyer’s Purchase of Securities. The Company acknowledges and agrees that each Buyer is acting solely in the
capacity of an arm’s length purchaser with respect to the Transaction Documents and the transactions contemplated hereby
and thereby. The Company further acknowledges that no Buyer is acting as a financial advisor or fiduciary of the Company or any
of its Subsidiaries (or in any similar capacity) with respect to the Transaction Documents and the transactions contemplated hereby
and thereby, and any advice given by a Buyer or any of its representatives or agents in connection with the Transaction Documents
and the transactions contemplated hereby and thereby is merely incidental to such Buyer’s purchase of the Securities. The
Company further represents to each Buyer that the Company’s decision to enter into the Transaction Documents has been based
solely on the independent evaluation by the Company and its representatives.


 


(g)No
General Solicitation; Fees and Commissions. Neither the Company, nor any of its Subsidiaries or affiliates, nor any Person
acting on its or their behalf, has engaged in any form of general solicitation or general advertising (within the meaning of Regulation
D) in connection with the offer or sale of the Securities. The Company shall be responsible for the payment of any placement agent’s
fees, financial advisory fees, or brokers’ commissions (other than for persons engaged by any Buyer or its investment advisor)
relating to or arising out of the transactions contemplated hereby. The Company shall pay, and hold each Buyer harmless against,
any liability, loss or expense (including, without limitation, attorney’s fees and out-of-pocket expenses) arising in connection
with any such claim. Notwithstanding the foregoing, neither the Company nor any of its Subsidiaries has engaged any placement
agent or other agent in connection with the sale of the Securities. 


 


(h)No
Integrated Offering. None of the Company, its Subsidiaries, any of their affiliates, and any Person acting on 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 require registration of any of the Securities under the 1933 Act, whether through integration with prior offerings
or otherwise. None of the Company, its Subsidiaries, their affiliates and any Person acting on their behalf will take any action
or steps referred to in the preceding sentence that would require registration of any of the Securities under the 1933 Act.

of Takeover Protections; Rights Agreement. The Company and its Board of Directors have taken all necessary action, if any,
in 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 Certificate of Incorporation or the laws of the jurisdiction
of its formation which is or could become applicable to any Buyer as a result of the transactions contemplated by this Agreement,
including, without limitation, the Company’s issuance of the Securities and any Buyer’s ownership of the Securities.
The Company has not adopted a stockholder rights plan or similar arrangement relating to accumulations of beneficial ownership
of Common Stock or a change in control of the Company.

of the Securities Exchange Act of 1934, as amended (the “1934 Act”) (all of the foregoing filed prior to the
date hereof, and all exhibits included therein and financial statements, notes and schedules thereto and documents incorporated

Buyers or their respective representatives true, correct and complete copies of the SEC Documents not available on the EDGAR system.

and the rules and regulations of the SEC promulgated thereunder applicable to the SEC Documents, and none of the SEC Documents,
at the time they were filed with the SEC, contained any untrue statement of a material fact or omitted to state a material fact
required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which
they were made, not misleading. As of their respective filing dates, the financial statements of the Company included in the SEC
Documents complied as to form in all material respects with applicable accounting requirements and the published rules and regulations
of the SEC with respect thereto. Such financial statements have been prepared in accordance with generally accepted accounting
principles, consistently applied, during the periods involved (“GAAP”) (except (i) as may be otherwise indicated

of the Company as of the dates thereof and the results of its operations and cash flows for the periods then ended (subject, in
the case of unaudited statements, to normal year-end audit adjustments).


 


(k)Absence
of Certain Changes, Undisclosed Events, Liabilities or Developments. Except as disclosed in Schedule  3 (k)
or as set forth in the SEC Documents, since June 30, 2016, (i) there has been no event, occurrence or development that would,
to the Company’s knowledge, reasonably be expected to result in a Material Adverse Effect, (ii) neither the Company nor
any of its Subsidiaries has incurred any liabilities (contingent or otherwise) other than (A) trade payables and accrued expenses

the Company’s financial statements pursuant to GAAP or disclosed in filings made with the SEC, (iii) the Company has not
altered its method of accounting, (iv) the Company has not (A) declared or paid any dividends, (B) sold any assets, individually

under any certificate of designations of any outstanding series of preferred stock of the Company (if any), its Certificate of
Incorporation or Bylaws or their organizational charter or memorandum of association or certificate of incorporation or articles
of association or bylaws, respectively. Neither the Company nor any of its Subsidiaries is in violation of any judgment, decree
or order or any statute, ordinance, rule or regulation applicable to the Company or any of its Subsidiaries, and neither the Company
nor any of its Subsidiaries will conduct its business in violation of any of the foregoing, except for possible violations which
could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. Without limiting the generality
of the foregoing, the Company is not in violation of any of the rules, regulations or requirements of the Principal Market and
has no knowledge of any facts or circumstances that would reasonably lead to delisting or suspension of the Common Stock by the
Principal Market in the foreseeable future. Except as set forth in Schedule  3 (l), during the one (1) year
prior to the date hereof, the Common Stock has been designated for quotation on the Principal Market. Except as set forth in Schedule
 3 (l), during the one (1) year prior to the date hereof, (i) trading in the Common Stock has not been suspended
by the SEC or the Principal Market and (ii) the Company has received no communication, written or oral, from the SEC or the Principal

in the judgment of the Company’s officers, has or is expected to have a Material Adverse Effect. Schedule  3

(x) “Indebtedness” of any Person means, without duplication (A) all indebtedness for borrowed money, (B) all
obligations issued, undertaken or assumed as the deferred purchase price of property or services, including, without limitation,
“capital leases” in accordance with GAAP (other than trade payables entered into in the ordinary course of business
consistent with past practice), (C) all reimbursement or payment obligations with respect to letters of credit, surety bonds and
other similar instruments, (D) all obligations evidenced by notes, bonds, debentures or similar instruments, including obligations
so evidenced incurred in connection with the acquisition of property, assets or businesses, (E) all indebtedness created or arising
under any conditional sale or other title retention agreement, or incurred as financing, in either case with respect to any property
or assets acquired with the proceeds of such indebtedness (even though the rights and remedies of the seller or bank under such
agreement in the event of default are limited to repossession or sale of such property), (F) all monetary obligations under any
leasing or similar arrangement which, in connection with GAAP, consistently applied for the periods covered thereby, is classified
as a capital lease, (G) all indebtedness referred to in clauses (A) through (F) above secured by (or for which the holder of such
Indebtedness has an existing right, contingent or otherwise, to be secured by) any mortgage, lien, pledge, charge, security interest
or other encumbrance upon or in any property or assets (including accounts and contract rights) owned by any Person, even though
the Person which owns such assets or property has not assumed or become liable for the payment of such indebtedness, and (H) all
Contingent Obligations in respect of indebtedness or obligations of others of the kinds referred to in clauses (A) through (G)
above; and (y) “Contingent Obligation” means, as to any Person, any direct or indirect liability, contingent
or otherwise, of that Person with respect to any Indebtedness, lease, dividend or other obligation of another Person if the primary
purpose or intent of the Person incurring such liability, or the primary effect thereof, is to provide assurance to the obligee
of such liability that such liability will be paid or discharged, or that any agreements relating thereto will be complied with,
or that the holders of such liability will be protected (in whole or in part) against loss with respect thereto.


 


(r)Litigation.
There is no action, suit, proceeding, inquiry or investigation before or by the Principal Market, any court, public board, government
agency, self-regulatory organization or body pending or, to the knowledge of the Company, threatened against or affecting the

or its Subsidiaries’ officers or directors, whether of a civil or criminal nature or otherwise, in their capacities as such,
except as set forth in Schedule  3 (r). The matters set forth in Schedule  3 (r) would
not reasonably be expected to have a Material Adverse Effect.

(s)Insurance.

risks and in such amounts as management of the Company believes to be prudent and customary in the businesses in which the Company
and its Subsidiaries are engaged. Neither the Company nor any such Subsidiary has been refused any insurance coverage sought or
applied for and neither the Company nor any such Subsidiary has any reason to believe that it will not be able to renew its existing
insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to
continue its business at a cost that would not have a Material Adverse Effect.


 


(t)Employee
Relations.


 


(i)Neither
the Company nor any of its Subsidiaries is a party to any collective bargaining agreement or employs any member of a union. The
Company and its Subsidiaries believe that their relations with their employees are good. No executive officer (as defined in Rule
501(f) under the 1933 Act) of the Company or any of its Subsidiaries has notified the Company or any such Subsidiary that such
officer intends to leave the Company or any such Subsidiary or otherwise terminate such officer’s employment with the Company
or any such Subsidiary. No executive officer of the Company or any of its Subsidiaries, to the knowledge of the Company or any
of its Subsidiaries, is, or is now expected to be, in violation of any material term of any employment contract, confidentiality,
disclosure or proprietary information agreement, non-competition agreement, or any other contract or agreement or any restrictive
covenant, and the continued employment of each such executive officer does not subject the Company or any of its Subsidiaries
to any liability with respect to any of the foregoing matters.


 


(ii)The
Company and its Subsidiaries are in compliance with all federal, state, local and foreign laws and regulations respecting labor,
employment and employment practices and benefits, terms and conditions of employment and wages and hours, except where failure
to be in compliance would not, either individually or in the aggregate, reasonably be expected to result in a Material Adverse
Effect.


 


(u)[Reserved.]


 


(v)Intellectual
Property Rights. The Company and its Subsidiaries own or possess adequate rights or licenses to use all trademarks, trade
names, service marks, service mark registrations, service names, original works of authorship, patents, patent rights, copyrights,
inventions, licenses, approvals, governmental authorizations, trade secrets and other intellectual property rights and all applications
and registrations therefor (“Intellectual Property Rights”) necessary to conduct their respective businesses
as now conducted. None of the Company’s Intellectual Property Rights have expired or terminated or have been abandoned or
are expected to expire or terminate or are expected to be abandoned, within three years from the date of this Agreement. The Company
does not have any knowledge of any infringement by the Company or its Subsidiaries of Intellectual Property Rights of others.
There is no claim, action or proceeding being made or brought, or to the knowledge of the Company or any of its Subsidiaries,
being threatened, against the Company or any of its Subsidiaries regarding its Intellectual Property Rights. Neither the Company
nor any of its Subsidiaries is aware of any facts or circumstances that might give rise to any of the foregoing infringements
or claims, actions or proceedings. The Company and its Subsidiaries have taken reasonable security measures to protect the secrecy,
confidentiality and value of all of their Intellectual Property Rights.

Laws. Except as would not reasonably be expected, individually or in the aggregate, to have a Material Adverse Effect: (i)
neither the Company nor its Subsidiaries is in violation of any Environmental Laws (as hereinafter defined), (ii) the Company
and its Subsidiaries have received all permits, licenses or other approvals required of them under applicable Environmental Laws
to conduct their respective businesses and (iii) the Company and its Subsidiaries are in compliance with all terms and conditions
of any such permit, license or approval. The term “Environmental Laws” means all federal, state, local or foreign
laws relating to pollution or protection of human health or the environment (including, without limitation, ambient air, surface
water, groundwater, land surface or subsurface strata), including, without limitation, laws relating to emissions, discharges,
releases or threatened releases of chemicals, pollutants, contaminants, or toxic or hazardous substances or wastes (collectively,
“Hazardous Materials”) into the environment, or otherwise relating to the manufacture, processing, distribution,
use, treatment, storage, disposal, transport or handling of Hazardous Materials, as well as all authorizations, codes, decrees,
demands or demand letters, injunctions, judgments, licenses, notices or notice letters, orders, permits, plans or regulations
issued, entered, promulgated or approved thereunder.

Company Status. Neither the Company nor any Subsidiary is, and upon consummation of the sale of the Securities, and for so

controls and procedures (as such term is defined in Rule 13a-15 under the 1934 Act) that are effective in ensuring that information
required to be disclosed by the Company in the reports that it files or submits under the 1934 Act is recorded, processed, summarized
and reported, within the time periods specified in the rules and forms of the SEC, including, without limitation, controls and
procedures designed to ensure that information required to be disclosed by the Company in the reports that it files or submits
under the 1934 Act is accumulated and communicated to the Company’s management, including its principal executive officer
or officers and its principal financial officer or officers, as appropriate, to allow timely decisions regarding required disclosure.

the Securities for any specified term; (ii) any Buyer, and counter-parties in “derivative” transactions to which any
such Buyer is a party, directly or indirectly, presently may have a “short” position in the Common Stock, and (iii)
each Buyer shall not be deemed to have any affiliation with or control over any arm’s length counter-party in any “derivative”

at various times during the period that the Securities are outstanding and (b) such hedging and/or trading activities, if any,
can reduce the value of the existing stockholders’ equity interest in the Company both at and after the time the hedging
and/or trading activities are being conducted. Subject to the provisions of Section 2(j) and Section 4(m), the Company acknowledges
that such aforementioned hedging and/or trading activities do not constitute a breach of this Agreement, the Notes, the Warrants,

information. No Buyer shall have any liability to the Company, its Subsidiaries, or any of its or their respective officers, directors,
affiliates, employees, stockholders or agents for any such disclosure. To the extent that the Company delivers any material, non-public
information to a Buyer without such Buyer’s consent, the Company hereby covenants and agrees that such Buyer shall not have
any duty of confidentiality to the Company, any of its Subsidiaries or any of their respective officers, directors, employees,
affiliates or agents with respect to, or a duty not to trade on the basis of, such material, non-public information. Subject to
the foregoing, neither the Company, its Subsidiaries nor any Buyer shall issue any press releases or any other public statements
with respect to the transactions contemplated hereby; provided, however, that the Company shall be entitled, without the prior
approval of any Buyer, to make any press release or other public disclosure with respect to such transactions (i) in substantial
conformity with the 8-K Filing and contemporaneously therewith and (ii) as is required by applicable law and regulations (provided
that in the case of clause (i) each Buyer shall be consulted by the Company in connection with any such press release or other
public disclosure prior to its release). Except for the Registration Statement required to be filed pursuant to Section 4(q) or
as required by applicable law, without the prior written consent of any applicable Buyer, neither the Company nor any of its Subsidiaries
or affiliates shall disclose the name of such Buyer in any filing, announcement, release or otherwise.

failure to satisfy the current public information requirement under Rule 144(c) or (ii) if the Company has ever been an issuer
described in Rule 144(i)(1)(i) or becomes such an issuer in the future, and the Company shall fail to satisfy any condition set

thirtieth day (pro rated for periods totaling less than thirty days) thereafter until the earlier of (i) the date such Public

Neither the Subordinated Agent nor any of its officers, directors, employees and agents shall have any liability to any Buyer
for any action taken or omitted to be taken in connection hereof except to the extent caused by its own gross negligence or willful

indirect or consequential, arising from or in connection with the performance by such Subordinated Agent Indemnitee of the duties
and obligations of Subordinated Agent pursuant hereto in the event that such losses, damages, liabilities, obligations, penalties,
actions, judgments, suits, fees, costs or expenses are a direct result of such Buyer’s breach of this Agreement or the Subordination
Agreement.

(ii)The
Subordinated Agent shall be entitled to rely upon any written notices, statements, certificates, orders or other documents or
any telephone message believed by it in good faith to be genuine and correct and to have been signed, sent or made by the proper
Person, and with respect to all matters pertaining to this Agreement or any of the other Transaction Documents and its duties
hereunder or thereunder, upon advice of counsel selected by it.


 


(iii)The
Subordinated Agent may resign from the performance of all its functions and duties hereunder and under the Notes at any time by
giving at least ten (10) Business Days prior written notice to the Company and each holder of the Notes. Such resignation shall
take effect upon the acceptance by a successor Subordinated Agent of appointment as provided below. Upon any such notice of resignation,
the holders of a majority of the outstanding principal amount of Notes shall appoint a successor Subordinated Agent. Upon the
acceptance of the appointment as Subordinated Agent, such successor Subordinated Agent shall succeed to and become vested with
all the rights, powers, privileges and duties of the retiring Subordinated Agent, and the retiring Subordinated Agent shall be
discharged from its duties and obligations under this Agreement and the Notes. After any Subordinated Agent’s resignation
hereunder, the provisions of this Section 4(o) shall inure to its benefit. If a successor Subordinated Agent shall not have been
so appointed within said ten (10) Business Day period, the retiring Subordinated Agent shall then appoint a successor Subordinated
Agent who shall serve until such time, if any, as the holders of a majority of the outstanding principal amount of Notes appoints

sole discretion, including, without limitation, by paying all fees of such successor Subordinated Agent, by having the Company
agree to indemnify any successor Subordinated Agent and by each of the Company executing an agency or similar agreement reasonably
requested or required by the successor Subordinated Agent.

of outstanding principal of the Notes held by such Buyer as of such 91st day after the date of issuance of such Note, which shall

5.REGISTER;
TRANSFER AGENT INSTRUCTIONS.


 


(a)Register.
The Company shall maintain at its principal executive offices (or such other office or agency of the Company as it may designate
by notice to each holder of Securities), a register for the Notes, the Warrants and the Additional Warrants, if any, in which
the Company shall record the name and address of the Person in whose name the Notes, the Warrants and the Additional Warrants,
if any, have been issued (including the name and address of each transferee), the principal amount of Notes held by such Person,
the number of Conversion Shares issuable pursuant to the terms of the Notes, the number of Warrant Shares issuable upon exercise
of the Warrants held by such Person and the number of Additional Warrant Shares issuable upon exercise of the Additional Warrants
held by such Person, if any. The Company shall keep the register open and available at all times during business hours for inspection
of any Buyer or its legal representatives.


 


(b)Transfer
Agent Instructions. The Company shall issue irrevocable instructions to its transfer agent, and any subsequent transfer agent,
in the form of Exhibit E attached hereto (the “Irrevocable Transfer Agent Instructions”) to issue certificates
or credit shares to the applicable balance accounts at DTC, registered in the name of each Buyer or its respective nominee(s),
for the Conversion Shares, the Warrant Shares or the Additional Warrant Shares, if any, issued at the Closing or pursuant to the
terms of the Notes or exercise of the Warrants or Additional Warrants, if any, in such amounts as specified from time to time
by each Buyer to the Company upon conversion of the Notes or exercise of the Warrants. The Company warrants that no instruction
other than the Irrevocable Transfer Agent Instructions referred to in this Section  5 (b), and stop transfer instructions to give
effect to Section  2 (f) hereof, will be given by the Company to its transfer agent with respect to the Securities, and that the
Securities shall otherwise be freely transferable on the books and records of the Company as and to the extent provided in this
Agreement and the other Transaction Documents. If a Buyer effects a sale, assignment or transfer of the Securities in accordance
with Section  2 (f), the Company shall permit the transfer and shall promptly instruct its transfer agent to issue one or more
certificates or credit shares to the applicable balance accounts at DTC in such name and in such denominations as specified by
such Buyer to effect such sale, transfer or assignment. In the event that such sale, assignment or transfer involves the Conversion
Shares, the Warrant Shares or the Additional Warrant Shares, if any, sold, assigned or transferred pursuant to an effective registration
statement or pursuant to Rule 144, the transfer agent shall issue such Securities to the Buyer, assignee or transferee, as the
case may be, without any restrictive legend. The Company acknowledges that a breach by it of its obligations hereunder will cause
irreparable harm to a Buyer. Accordingly, the Company acknowledges that the remedy at law for a breach of its obligations under
this Section  5 (b) will be inadequate and agrees, in the event of a breach or threatened breach by the Company of the provisions
of this Section  5 (b), that a Buyer shall be entitled, in addition to all other available remedies, to an order and/or injunction
restraining any breach and requiring immediate issuance and transfer, without the necessity of showing economic loss and without
any bond or other security being required.

8.MISCELLANEOUS.


 


(a)Governing

Agreement shall be governed by the internal laws of the State of New York, without giving effect to any choice of law or conflict
of law provision or rule (whether of the State of New York or any other jurisdictions) that would cause the application of the
laws of any jurisdictions other than the State 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, and hereby irrevocably waives, and
agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any
such court, that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such suit, action or
proceeding is improper. 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 to such party at the address for such 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 manner permitted by law. EACH PARTY HEREBY IRREVOCABLY
WAIVES ANY RIGHT IT MAY HAVE, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION
WITH OR ARISING OUT OF THIS AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREBY.


 


(b)Counterparts.
This Agreement and any amendments hereto may be executed and delivered in two or more counterparts, and by the different parties
hereto in separate counterparts, each of which when executed shall be deemed to be an original, but all of which taken together
shall constitute one and the same agreement, and shall become effective when counterparts have been signed by each party hereto
and delivered to the other parties hereto, it being understood that all parties need not sign the same counterpart. In the event
that any signature to this Agreement or any amendment hereto 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. No party hereto shall raise the use of a facsimile machine or e-mail delivery of a “.pdf”
format data file to deliver a signature to this Agreement or any amendment hereto or the fact that such signature was transmitted
or communicated through the use of a facsimile machine or e-mail delivery of a “.pdf” format data file as a defense
to the formation or enforceability of a contract and each party hereto forever waives any such defense


 


(c)Headings.
The headings of this Agreement are for convenience of reference and shall not form part of, or affect the interpretation of, this
Agreement.


 






    	 	- 19 -	 



    


    

 


(d)Severability.
If any provision of this Agreement is prohibited by law or otherwise determined to be invalid or unenforceable by a court of competent
jurisdiction, the provision that would otherwise be prohibited, invalid or unenforceable shall be deemed amended to apply to the
broadest extent that it would be valid and enforceable, and the invalidity or unenforceability of such provision shall not affect
the validity of the remaining provisions of this Agreement so long as this Agreement as so modified continues to express, without
material change, the original intentions of the parties as to the subject matter hereof and the prohibited nature, invalidity
or unenforceability of the provision(s) in question does not substantially impair the respective expectations or reciprocal obligations
of the parties or the practical realization of the benefits that would otherwise be conferred upon the parties. The parties will
endeavor in good faith negotiations to replace the prohibited, invalid or unenforceable provision(s) with a valid provision(s),
the effect of which comes as close as possible to that of the prohibited, invalid or unenforceable provision(s).


 


(e)Entire
Agreement; Amendments. This Agreement and the other Transaction Documents supersede all other prior oral or written agreements
between the Buyers, the Company, their affiliates and Persons acting on their behalf with respect to the matters discussed herein,
and this Agreement, the other Transaction Documents and the instruments referenced herein and therein contain the entire understanding
of the parties with respect to the matters covered herein and therein and, except as specifically set forth herein or therein,
neither the Company nor any Buyer makes any representation, warranty, covenant or undertaking with respect to such matters. Provisions
of this Agreement may be amended and the observance thereof may be waived (either generally or in a particular instance and either
retroactively or prospectively), only with the written consent of the Company and the holders of at least a majority of the aggregate
number of the Conversion Shares and the Warrant Shares issued or issuable under the Notes (calculated using the Assumed Conversion
Price) and Warrants (without regard to any limitation on conversion or exercise set forth therein) (as adjusted for any stock
dividend, stock split, stock combination, reclassification or similar transaction occurring after the date thereof) (the “Required
Holders”); provided that any such amendment or waiver that complies with the foregoing but that disproportionately,
materially and adversely affects the rights and obligations of any Buyer relative to the comparable rights and obligations of
the other Buyers shall require the prior written consent of such adversely affected Buyer. Any amendment or waiver effected in
accordance with this Section  8 (e) shall be binding upon each Buyer and holder of Securities and the Company. No such amendment
shall be effective to the extent that it applies to less than all of the Buyers or holders of Securities. No consideration shall
be offered or paid to any Person to amend or consent to a waiver or modification of any provision of any of the Transaction Documents
unless the same consideration (other than the reimbursement of legal fees) also is offered to all of the parties to the Transaction
Documents, holders of Notes or holders of the Warrants, as the case may be. The Company has not, directly or indirectly, made
any agreements with any Buyers relating to the terms or conditions of the transactions contemplated by the Transaction Documents
except as set forth in the Transaction Documents. Without limiting the foregoing, the Company confirms that, except as set forth
in this Agreement, no Buyer has made any commitment or promise or has any other obligation to provide any financing to the Company
or otherwise.

or (c) any cause of action, suit or claim brought or made against such Indemnitee by a third party (including for these purposes
a derivative action brought on behalf of the Company) and arising out of or resulting from (i) the execution, delivery, performance
or enforcement of the Transaction Documents or any other certificate, instrument or document contemplated hereby or thereby, (ii)
any transaction financed or to be financed in whole or in part, directly or indirectly, with the proceeds of the issuance of the
Securities or (iii) the status of such Buyer or holder of the Securities as an investor in the Company pursuant to the transactions
contemplated by the Transaction Documents, except, in each case, with respect to any Indemnified Liabilities that resulted from
any Indemnitee’s gross negligence, willful misconduct or fraud. To the extent that the foregoing undertaking by the Company
may be unenforceable for any reason, the Company shall make the maximum contribution to the payment and satisfaction of each of
the Indemnified Liabilities that is permissible under applicable law.

(ii)Promptly
after receipt by an Indemnitee under this Section 8(k) of notice of the commencement of any action or proceeding (including any
governmental action or proceeding) involving an Indemnified Liability, such Indemnitee shall, if a claim for indemnification in
respect thereof is to be made against any indemnifying party under this Section 8(k), deliver to the indemnifying party a written
notice of the commencement thereof, and the indemnifying party shall have the right to participate in, and, to the extent the
indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume control of the defense thereof
with counsel mutually satisfactory to the indemnifying party and the Indemnitee; provided, however, that an Indemnitee
shall have the right to retain its own counsel with the fees and expenses of not more than one counsel for such Indemnitee to
be paid by the indemnifying party, if, in the reasonable opinion of the Indemnitee, the representation by such counsel of the
Indemnitee and the indemnifying party would be inappropriate due to actual or potential differing interests between such Indemnitee
and any other party represented by such counsel in such proceeding. Legal counsel referred to in the immediately preceding sentence
shall be selected by the Buyer holding at least a majority of the aggregate principal amount of the Notes. The Indemnitee shall
cooperate fully with the indemnifying party in connection with any negotiation or defense of any such action or Indemnified Liabilities
by the indemnifying party and shall furnish to the indemnifying party all information reasonably available to the Indemnitee that
relates to such action or Indemnified Liabilities. The indemnifying party shall keep the Indemnitee fully apprised at all times
as to the status of the defense or any settlement negotiations with respect thereto. No indemnifying party shall be liable for
any settlement of any action, claim or proceeding effected without its prior written consent, provided, however,
that the indemnifying party shall not unreasonably withhold, delay or condition its consent. No indemnifying party shall, without
the prior written consent of the Indemnitee, which consent shall not be unreasonably withheld conditioned or delayed, consent
to entry of any judgment or enter into any settlement or other compromise which (i) does not include as an unconditional term
thereof the giving by the claimant or plaintiff to such Indemnitee of a release from all liability in respect to such Indemnified
Liabilities or litigation, (ii) requires any admission of wrongdoing by such Indemnitee, or (iii) obligates or requires an Indemnitee
to take, or refrain from taking, any action. Following indemnification as provided for hereunder, the indemnifying party shall
be subrogated to all rights of the Indemnitee with respect to all third parties, firms or corporations relating to the matter
for which indemnification has been made. The failure to deliver written notice to the indemnifying party within a reasonable time
of the commencement of any such action shall not relieve such indemnifying party of any liability to the Indemnitee under this
Section 8(k), except to the extent that the indemnifying party is prejudiced in its ability to defend such action.


 






    	 	- 22 -	 



    


    

 


(iii)The
indemnification required by this Section 8(k) 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 Indemnified Liabilities are incurred.


 


(iv)The
indemnity agreements contained herein shall be in addition to (x) any cause of action or similar right of the Indemnitee against
the indemnifying party or others, and (y) any liabilities the indemnifying party may be subject to pursuant to the law.


 


(l)No
Strict Construction. The language used in this Agreement will be deemed to be the language chosen by the parties to express
their mutual intent, and no rules of strict construction will be applied against any party.


 


(m)Remedies.
Each Buyer and each holder of the Securities shall have all rights and remedies set forth in the Transaction Documents and all
rights and remedies which such holders have been granted at any time under any other agreement or contract and all of the rights
which such holders have under any law. Any Person having any rights under any provision of this Agreement shall be entitled to
enforce such rights specifically (without posting a bond or other security), to recover damages by reason of any breach of any
provision of this Agreement and to exercise all other rights granted by law. Furthermore, the Company recognizes that in the event
that it fails to perform, observe, or discharge any or all of its obligations under the Transaction Documents, any remedy at law
may prove to be inadequate relief to the Buyers. The Company therefore agrees that the Buyers shall be entitled to seek temporary
and permanent injunctive relief in any such case without the necessity of proving actual damages and without posting a bond or
other security.


 


(n)Rescission
and Withdrawal Right. Notwithstanding anything to the contrary contained in (and without limiting any similar provisions of)
the Transaction Documents, whenever any Buyer 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 Buyer 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.


 


(o)Payment
Set Aside. To the extent that the Company makes a payment or payments to the Buyers hereunder or pursuant to any of the other
Transaction Documents or the Buyers enforce or exercise their rights hereunder or 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, foreign, 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.


 


(p)Independent
Nature of Buyers’ Obligations and Rights. The obligations of each Buyer under any Transaction Document are several and
not joint with the obligations of any other Buyer, and no Buyer shall be responsible in any way for the performance of the obligations
of any other Buyer under any Transaction Document. Nothing contained herein or in any other Transaction Document, and no action
taken by any Buyer pursuant hereto or thereto, shall be deemed to constitute the Buyers as, and the Company acknowledges that
the Buyers do not so constitute, a partnership, an association, a joint venture or any other kind of entity, or create a presumption
that the Buyers are in any way acting in concert or as a group, and the Company shall not assert any such claim with respect to
such obligations or the transactions contemplated by the Transaction Documents and the Company acknowledges that the Buyers are
not acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Documents.
The Company acknowledges and each Buyer confirms that it has independently participated in the negotiation of the transaction
contemplated hereby with the advice of its own counsel and advisors. Each Buyer shall be entitled to independently protect and
enforce its rights, including, without limitation, the rights arising out of this Agreement or out of any other Transaction Documents,
and it shall not be necessary for any other Buyer to be joined as an additional party in any proceeding for such purpose.


 


(q)Subordination
Agreement. The Company and each Buyer acknowledge and agree that, notwithstanding anything to the contrary herein, the rights
of the Buyer pursuant to the terms of each of the Transaction Documents are subject to the prohibitions on cash payments to the
Buyer by the Company set forth in the Subordination Agreement, except as explicitly permitted in the Subordination Agreement.

Ener-Core,
Inc., a company incorporated under the laws of Delaware (the “Company”), hereby certifies that, for good and
valuable consideration, the receipt and sufficiency of which are hereby acknowledged,
[HOLDER], the registered holder hereof or its permitted assigns (the “Holder”), is entitled, subject
to the terms set forth below, to purchase from the Company, at the Exercise Price (as defined below) then in effect, at any time
or times on or after the Issuance Date, but not after 11:59 p.m., New York time, on the Expiration Date, (as defined below), ______________
(_____________) fully paid nonassessable shares of Common Stock (as defined below), subject to adjustment as provided herein
(the “Warrant Shares”). Except as otherwise defined herein, capitalized terms in this Warrant to Purchase
Common Stock (including any Warrants to Purchase Common Stock issued in exchange, transfer or replacement hereof, this “Warrant”),
shall have the meanings set forth in Section 16. This Warrant is one of the Warrants to purchase Common Stock (the “Additional
Warrants”) issued pursuant to Section 4(r) of that certain Securities Purchase Agreement, dated as of September 1, 2016
(the “Subscription Date”), by and among the Company and the investors (the “Buyers”)
referred to therein (the “Securities Purchase Agreement”).


 










 






    

    


    

 


1. EXERCISE
OF WARRANT.





 


(a) Mechanics
of Exercise. Subject to the terms and conditions hereof (including, without limitation, the limitations set forth in Section
1(f)), this Warrant may be exercised by the Holder at any time or times on or after the Issuance Date, in whole or in
part, by delivery (whether via facsimile, electronic mail or otherwise) of a written notice, in the form attached hereto as Exhibit
A (the “Exercise Notice”), of the Holder’s election to exercise this Warrant. Within two (2)
days following the date of delivery of the Exercise Notice, the Holder shall make payment to the Company of an amount equal
to the Exercise Price in effect on the date of such exercise multiplied by the number of Warrant Shares as to which this
Warrant is being exercised (the “Aggregate Exercise Price”) in cash by wire transfer of immediately
available funds or, if the provisions of Section 1(d) are applicable, by notifying the Company that this Warrant is being
exercised pursuant to a Cashless Exercise (as defined in Section 1(d)). The Holder shall not be required to deliver the
original Warrant in order to effect an exercise hereunder, nor shall any ink-original signature or medallion guarantee (or
other type of guarantee or notarization) with respect to any Exercise Notice be required. Execution and delivery of the
Exercise Notice with respect to less than all of the Warrant Shares shall have the same effect as cancellation of the
original Warrant and issuance of a new Warrant evidencing the right to purchase the remaining number of Warrant Shares. On or
before the first (1st) Trading Day following the date on which the Company has received the applicable Exercise
Notice, the Company shall transmit by facsimile or electronic mail an acknowledgment of confirmation of receipt of the
Exercise Notice, in the form attached to the Exercise Notice, to the Holder and the Company’s transfer agent (the
“Transfer Agent”). So long as the Holder delivers the Aggregate Exercise Price (or notice of a Cashless
Exercise) on or prior to the second (2nd) Trading Day following the date on which the Exercise Notice has been
delivered to the Company, then on or prior to the earlier of (i) the third (3rd) Trading Day following the date on
which the Exercise Notice has been delivered to the Company and (ii) the number of Trading Days comprising the Standard
Settlement Period (but in no event sooner than the 2nd Trading Day following the date on which the Exercise Notice has been
delivered to the Company, unless the Holder has elected to deliver a notice of a Cashless Exercise), or, if the Holder does
not deliver the Aggregate Exercise Price (or notice of a Cashless Exercise) on or prior to the second (2nd)
Trading Day following the date on which the Exercise Notice has been delivered to the Company, then on or prior to the second
(2nd) Trading Day following the date on which the Aggregate Exercise Price (or notice of a Cashless Exercise) is
delivered (the “Share Delivery Date”), the Company shall (X) provided that the Transfer Agent is
participating in The Depository Trust Company (“DTC”) Fast Automated Securities Transfer Program, credit
such aggregate number of Warrant Shares to which the Holder is entitled pursuant to such exercise to the Holder’s or
its designee’s balance account with DTC through its Deposit / Withdrawal At Custodian system, or (Y) if the Transfer
Agent is not participating in the DTC Fast Automated Securities Transfer Program, issue and dispatch by overnight courier to
the address as specified in the Exercise Notice, a certificate, registered in the Company’s share register in the name
of the Holder or its designee, for the number of Warrant Shares to which the Holder is entitled pursuant to such exercise.
The Company shall be responsible for all fees and expenses of the Transfer Agent and all fees and expenses with respect to
the issuance of Warrant Shares via DTC, if any, including without limitation for same day processing. Upon delivery of the
Exercise Notice, the Holder shall be deemed for purposes of Rule 200(b) of Regulation SHO to have become the owner of the
Warrant Shares with respect to which this Warrant has been exercised, irrespective of the date such Warrant Shares are
credited to the Holder’s DTC account or the date of delivery of the certificates evidencing such Warrant Shares, as the
case may be, provided that the Holder delivers the Aggregate Exercise Price (or a duly executed notice of a Cashless
Exercise) on or prior to the second (2nd) Trading Day following the date on which the Exercise Notice has been
delivered to the Company. If this Warrant is physically delivered to the Company in connection with any exercise pursuant to
this Section 1(a) and the number of Warrant Shares represented by this Warrant submitted for exercise is greater than the
number of Warrant Shares being acquired upon an exercise, then the Company shall as soon as practicable and in no event
later than three (3) Trading Days after any exercise and at its own expense, issue and deliver to the Holder (or its
designee) a new Warrant (in accordance with Section 7(d)) representing the right to purchase the number of Warrant Shares
issuable immediately prior to such exercise under this Warrant, less the number of Warrant Shares with respect to which this
Warrant is exercised. No fractional Warrant Shares are to be issued upon the exercise of this Warrant, but rather the number
of Warrant Shares to be issued shall be rounded to the nearest whole number. The Company shall pay any and all transfer,
stamp, issuance and similar taxes, costs and expenses (including, without limitation, fees and expenses of the Transfer
Agent) which may be payable with respect to the issuance and delivery of Warrant Shares upon exercise of this Warrant. The
Company’s obligations to issue and deliver Warrant Shares in accordance with the terms and subject to the conditions
hereof are absolute and unconditional, irrespective of any action or inaction by the Holder to enforce the same, any waiver
or consent with respect to any provision hereof, the recovery of any judgment against any Person or any action to enforce the
same, or any setoff, counterclaim, recoupment, limitation or termination; provided, however, that the Company
shall not be required to deliver Warrant Shares with respect to an exercise prior to the Holder’s delivery of the
Aggregate Exercise Price (or notice of a Cashless Exercise) with respect to such exercise. As used herein, “Standard
Settlement Period” means the standard settlement period, expressed in a number of Trading Days, on the
Company’s primary trading market or quotation system with respect to the Company’s Common Stock that is in effect
on the date of receipt of an applicable Exercise Notice.


 






    	 	- 2 -	 



    


    

 


(b)
Exercise Price. For purposes of this Warrant, “Exercise Price” means $4.00, subject to adjustment as
provided herein.


 


(c) Company’s
Failure to Timely Deliver Securities. If either (I) the Company shall fail for any reason or for no reason to issue to
the Holder on or prior to the applicable Share Delivery Date, if (x) the Transfer Agent is not participating in the DTC Fast
Automated Securities Transfer Program, a certificate for the number of shares of Common Stock to which the Holder is entitled
and register such Common Stock on the Company’s share register or (y) the Transfer Agent is participating in the DTC
Fast Automated Securities Transfer Program, to credit the Holder’s balance account with DTC, for such number of shares
of Common Stock to which the Holder is entitled upon the Holder’s exercise of this Warrant or (II) a registration
statement covering the resale of the Warrant Shares that are the subject of the Exercise Notice (the “Exercise
Notice Warrant Shares”) is not available for the resale of such Exercise Notice Warrant Notice Shares and (x) the
Company fails to promptly, but in no event later than one (1) Business Day after such registration statement becomes
unavailable, to so notify the Holder and (y) the Company is unable to deliver the Exercise Notice Warrant Shares
electronically without any restrictive legend by crediting such aggregate number of Exercise Notice Warrant Shares to the
Holder’s or its designee’s balance account with DTC through its Deposit / Withdrawal At Custodian system (the
event described in the immediately foregoing clause (II) is hereinafter referred to as a “Notice Failure”
and together with the event described in clause (I) above, an “Exercise Failure”), then, in addition to
all other remedies available to the Holder, if on or prior to the applicable Share Delivery Date either (I) if the Transfer
Agent is not participating in the DTC Fast Automated Securities Transfer Program, the Company shall fail to issue and deliver
a certificate to the Holder and register such shares of Common Stock on the Company’s share register or, if the
Transfer Agent is participating in the DTC Fast Automated Securities Transfer Program, credit the Holder’s balance
account with DTC for the number of shares of Common Stock to which the Holder is entitled upon the Holder’s exercise
hereunder or pursuant to the Company’s obligation pursuant to clause (ii) below or (II) if a Notice Failure occurs, and
if on or after such Trading Day the Holder purchases (in an open market transaction or otherwise) Common Stock to deliver in
satisfaction of a sale by the Holder of shares of Common Stock issuable upon such exercise that the Holder anticipated
receiving from the Company (a “Buy-In”), then the Company shall, within three (3) Trading Days after the
Holder’s request and in the Holder’s discretion, either (i) pay cash to the Holder in an amount equal to the
Holder’s total purchase price (including brokerage commissions and other out-of-pocket expenses, if any) for the shares
of Common Stock so purchased (the “Buy-In Price”), at which point the Company’s obligation to
deliver such certificate (and to issue such shares of Common Stock) or credit such Holder’s balance account with DTC
for such shares of Common Stock shall terminate, or (ii) promptly honor its obligation to deliver to the Holder a certificate
or certificates representing such shares of Common Stock or credit such Holder’s balance account with DTC, as
applicable, and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over the product of (A)
such number of shares of Common Stock, times (B) any trading price of the Common Stock selected by the Holder in writing as
in effect at any time during the period beginning on the applicable Exercise Date and ending on the applicable Share Delivery
Date. Nothing shall limit the Holder’s right to pursue any other remedies available to it hereunder, at law or in
equity, including, without limitation, a decree of specific performance and/or injunctive relief with respect to the
Company’s failure to timely deliver certificates representing Warrant Shares (or to electronically deliver such Warrant
Shares) upon the exercise of this Warrant as required pursuant to the terms hereof. While this Warrant is outstanding, the
Company shall cause its transfer agent to participate in the DTC Fast Automated Securities Transfer Program. In addition
to the foregoing rights, if the Company fails to deliver the applicable number of Warrant Shares upon an exercise pursuant to
Section 1 by the applicable Share Delivery Date, then the Holder shall have the right to rescind such exercise in whole or in
part and retain and/or have the Company return, as the case may be, any portion of this Warrant that has not been exercised
pursuant to such Exercise Notice; provided that the rescission of an exercise shall not affect the Company’s
obligation to make any payments that have accrued prior to the date of such notice pursuant to this Section 1(c) or
otherwise, and (ii) if a registration statement covering the resale of the Warrant Shares that are subject to an Exercise
Notice is not available for the resale of such Exercise Notice Warrant Shares and the Holder has submitted an Exercise Notice
prior to receiving notice of the non-availability of such registration statement and the Company has not already delivered
the Warrant Shares underlying such Exercise Notice electronically without any restrictive legend by crediting such aggregate
number of Warrant Shares to which the Holder is entitled pursuant to such exercise to the Holder’s or its
designee’s balance account with DTC through its Deposit / Withdrawal At Custodian system, the Holder shall have the
option, by delivery of notice to the Company, to (x) rescind such Exercise Notice in whole or in part and retain or have
returned, as the case may be, any portion of this Warrant that has not been exercised pursuant to such Exercise Notice; provided
that the rescission of an Exercise Notice shall not affect the Company’s obligation to make any payments that have
accrued prior to the date of such notice pursuant to this Section 1(c) or otherwise, and/or (y) switch some or all of such
Exercise Notice from a cash exercise to a Cashless Exercise.

(d) Cashless
Exercise.  Notwithstanding anything contained herein to the contrary, unless all of the Warrant Shares that are
subject to an Exercise Notice are registered for resale pursuant to an effective registration statement and are issuable
without any restrictive legends, the Holder may, in its sole discretion, exercise this Warrant in whole or in part and, in
lieu of making the cash payment otherwise contemplated to be made to the Company upon such exercise in payment of the
Aggregate Exercise Price, elect instead to receive upon such exercise the “Net Number” of shares of Common Stock
determined according to the following formula (a “Cashless Exercise”):


 


Net
Number = (A x B) - (A x C)

For
purposes of the foregoing formula:


 





	 	A
    =	the
    total number of shares with respect to which this Warrant is then being  exercised.
	 	 	 
	 	B
    =	the
    arithmetic average of the Closing Sale Prices of the Common Stock for the five (5) consecutive Trading Days ending on the
    date immediately preceding the date of the Exercise Notice.
	 	 	 
	 	C
    =	the
    Exercise Price then in effect for the applicable Warrant Shares at the time of such exercise.
	 	 	 
	 	D
    =	as
    applicable: (i) the Closing Sale Price of the Common Stock on the Trading Day immediately preceding the date of the applicable
    Exercise Notice if such Exercise Notice is (1) both executed and delivered pursuant to Section 1(a) hereof on a day that
    is not a Trading Day or (2) both executed and delivered pursuant to Section 1(d) hereof on a Trading Day prior to the
    opening of “regular trading hours” (as defined in Rule 600(b)(64) of Regulation NMS promulgated under the federal
    securities laws) on such Trading Day, (ii) the Bid Price of the Common Stock as of the time of the Holder’s execution
    of the applicable Exercise Notice if such Exercise Notice is executed during “regular trading hours” on a Trading
    Day and is delivered within two (2) hours thereafter pursuant to Section 1(a) hereof, or (iii) the Closing Sale Price
    of the Common Stock on the date of the applicable Exercise Notice if the date of such Exercise Notice is a Trading Day and
    such Exercise Notice is both executed and delivered pursuant to Section 1(a) hereof after the close of “regular
    trading hours” on such Trading Day.




 


If
Warrant Shares are issued in such a cashless exercise, the Company acknowledges and agrees that in accordance with Section 3(a)(9)
of the Securities Act of 1933, as amended (the “1933 Act”), the Warrant Shares shall take on the characteristics
of the Warrants being exercised, and the holding period of the Warrants being exercised may be tacked on to the holding period
of the Warrant Shares. The Company agrees not to take any position contrary to this Section 1(d).


 


(e) Disputes.
In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the Warrant Shares,
the Company shall promptly issue to the Holder the number of Warrant Shares that are not disputed and resolve such dispute in
accordance with Section 11.

(f) Beneficial
Ownership. Notwithstanding anything to the contrary contained herein, the Company shall not effect the exercise of any
portion of this Warrant, and the Holder shall not have the right to exercise any portion of this Warrant, pursuant to the
terms and conditions of this Warrant and any such exercise shall be null and void and treated as if never made, to the extent
that after giving effect to such exercise, the Holder together with the other Attribution Parties collectively would
beneficially own in excess of 9.99% (the “Maximum Percentage”) of the number of shares of Common Stock
outstanding immediately after giving effect to such exercise. For purposes of the foregoing sentence, the aggregate number of
shares of Common Stock beneficially owned by the Holder and the other Attribution Parties shall include the number of shares
of Common Stock held by the Holder and all other Attribution Parties plus the number of shares of Common Stock issuable upon
exercise of this Warrant with respect to which the determination of such sentence is being made, but shall exclude the number
of shares of Common Stock which would be issuable upon (A) exercise of the remaining, unexercised portion of this Warrant
beneficially owned by the Holder or any of the other Attribution Parties and (B) exercise or conversion of the unexercised or
unconverted portion of any other securities of the Company (including, without limitation, any convertible notes or
convertible preferred stock or warrants, including the other Additional Warrants) beneficially owned by the Holder or any
other Attribution Party subject to a limitation on conversion or exercise analogous to the limitation contained in this
Section 1(f). For purposes of this Section 1(f), beneficial ownership shall be calculated in accordance with Section 13(d) of
the Securities Exchange Act of 1934, as amended (the “1934 Act”). For purposes of this Warrant, in
determining the number of outstanding shares of Common Stock the Holder may acquire upon the exercise of this Warrant without
exceeding the Maximum Percentage, the Holder may rely on the number of outstanding shares of Common Stock as reflected in (x)
the Company’s most recent Annual Report on Form 10-K, Quarterly Report on Form 10-Q and Current Reports on Form 8-K or
other public filing with the Securities and Exchange Commission (the “SEC”), as the case may be, (y) a
more recent public announcement by the Company or (3) any other written notice by the Company or the Transfer Agent setting
forth the number of shares of Common Stock outstanding (the “Reported Outstanding Share Number”). If the
Company receives an Exercise Notice from the Holder at a time when the actual number of outstanding shares of Common Stock is
less than the Reported Outstanding Share Number, the Company shall (i) notify the Holder in writing of the number of shares
of Common Stock then outstanding and, to the extent that such Exercise Notice would otherwise cause the Holder’s
beneficial ownership, as determined pursuant to this Section 1(f), to exceed the Maximum Percentage, the Holder must notify
the Company of a reduced number of Warrant Shares to be purchased pursuant to such Exercise Notice (the number of shares by
which such purchase is reduced, the “Reduction Shares”) and (ii) as soon as reasonably practicable, the
Company shall return to the Holder any exercise price paid by the Holder for the Reduction Shares. For any reason at any
time, upon the written or oral request of the Holder, the Company shall within one (1) Business Day confirm orally and in
writing or by electronic mail to the Holder the number of shares of Common Stock then outstanding. In any case, the number of
outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the
Company, including this Warrant, by the Holder and any other Attribution Party since the date as of which the Reported
Outstanding Share Number was reported. In the event that the issuance of Common Stock to the Holder upon exercise of this
Warrant results in the Holder and the other Attribution Parties being deemed to beneficially own, in the aggregate, more than
the Maximum Percentage of the number of outstanding shares of Common Stock (as determined under Section 13(d) of the 1934
Act), the number of shares so issued by which the Holder’s and the other Attribution Parties’ aggregate
beneficial ownership exceeds the Maximum Percentage (the “Excess Shares”) shall be deemed null and void
and shall be cancelled ab initio, and the Holder shall not have the power to vote or to transfer the Excess Shares. As
soon as reasonably practicable after the issuance of the Excess Shares has been deemed null and void, the Company shall
return to the Holder the exercise price paid by the Holder for the Excess Shares. Upon delivery of a written notice to the
Company, the Holder may from time to time increase or decrease the Maximum Percentage to any other percentage not in excess
of 9.99% as specified in such notice; provided that (i) any such increase in the Maximum Percentage will not be effective
until the sixty-first (61st) day after such notice is delivered to the Company and (ii) any such increase or
decrease will apply only to the Holder and the other Attribution Parties and not to any other holder of Warrants that is not
an Attribution Party of the Holder. For purposes of clarity, the shares of Common Stock issuable pursuant to the terms of
this Warrant in excess of the Maximum Percentage shall not be deemed to be beneficially owned by the Holder for any purpose
including for purposes of Section 13(d) or Rule 16a-1(a)(1) of the 1934 Act. No prior inability to exercise this Warrant
pursuant to this paragraph shall have any effect on the applicability of the provisions of this paragraph with respect to any
subsequent determination of exercisability. The provisions of this paragraph shall be construed and implemented in a manner
otherwise than in strict conformity with the terms of this Section 1(f) to the extent necessary to correct this paragraph or
any portion of this paragraph which may be defective or inconsistent with the intended beneficial ownership limitation
contained in this Section 1(f) or to make changes or supplements necessary or desirable to properly give effect to such
limitation. The limitation contained in this paragraph may not be waived and shall apply to a successor holder of this
Warrant.


 






    	 	- 5 -	 



    


    

 


(g) Required
Reserve Amount.  So long as this Warrant remains outstanding, the Company shall at all times keep reserved for
issuance under this Warrant a number of shares of Common Stock at least equal to 100% of the maximum number of shares of
Common Stock as shall be necessary to satisfy the Company’s obligation to issue shares of Common Stock under the
Warrants then outstanding (without regard to any limitations on exercise) (the “Required Reserve Amount”); provided
that at no time shall the number of shares of Common Stock reserved pursuant to this Section 1(g) be reduced other than in
connection with any exercise of Warrants or such other event covered by Section 2(c) below. The Required Reserve Amount
(including, without limitation, each increase in the number of shares so reserved) shall be allocated pro rata among the
holders of the Warrants based on the number of shares of Common Stock issuable upon exercise of Warrants held by each holder
thereof on the Issuance Date (without regard to any limitations on exercise) (the “Authorized Share
Allocation”). In the event that a holder shall sell or otherwise transfer any of such holder’s Warrants, each
transferee shall be allocated a pro rata portion of such holder’s Authorized Share Allocation. Any shares of Common
Stock reserved and allocated to any Person which ceases to hold any Warrants shall be allocated to the remaining holders of
Warrants, pro rata based on the number of shares of Common Stock issuable upon exercise of the Warrants then held by such
holders thereof (without regard to any limitations on exercise).


 


(h) Insufficient
Authorized Shares. If at any time while this Warrant remains outstanding the Company does not have a sufficient number
of authorized and unreserved shares of Common Stock to satisfy its obligation to reserve for issuance the Required Reserve
Amount (an “Authorized Share Failure”), then the Company shall immediately take all action necessary to
increase the Company’s authorized shares of Common Stock to an amount sufficient to allow the Company to reserve the
Required Reserve Amount for this Warrant then outstanding. Without limiting the generality of the foregoing sentence, as soon
as practicable after the date of the occurrence of an Authorized Share Failure, but in no event later than seventy-five (75)
days after the occurrence of such Authorized Share Failure, the Company shall hold a meeting of its stockholders for the
approval of an increase in the number of authorized shares of Common Stock. In connection with such meeting, the Company
shall provide each stockholder with a proxy statement and shall use its best efforts to solicit its stockholders’
approval of such increase in authorized shares of Common Stock and to cause its board of directors to recommend to the
stockholders that they approve such proposal. Notwithstanding the foregoing, if any such time of an Authorized Share Failure,
the Company is able to obtain the written consent of a majority of the shares of its issued and outstanding shares of Common
Stock to approve the increase in the number of authorized shares of Common Stock, the Company may satisfy this obligation by
obtaining such consent and submitting for filing with the SEC an Information Statement on Schedule 14C.


 


2. ADJUSTMENT
OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES. The Exercise Price and the number of Warrant Shares shall be adjusted
from time to time as follows:


 


(a)Voluntary
Adjustment By Company. The Company may at any time during the term of this Warrant reduce the then current Exercise Price
to any amount and for any period of time deemed appropriate by the Board of Directors of the Company.


 


(b) Adjustment
Upon Subdivision or Combination of Common Stock. If the Company at any time on or after the Subscription Date subdivides
(by any stock split, stock dividend, recapitalization or otherwise) one or more classes of its outstanding shares of Common
Stock into a greater number of shares, the Exercise Price in effect immediately prior to such subdivision will be
proportionately reduced and the number of Warrant Shares will be proportionately increased. If the Company at any time on or
after the Subscription Date combines (by combination, reverse stock split or otherwise) one or more classes of its
outstanding shares of Common Stock into a smaller number of shares, the Exercise Price in effect immediately prior to such
combination will be proportionately increased and the number of Warrant Shares will be proportionately decreased. Any
adjustment under this Section 2(b) shall become effective at the close of business on the date the subdivision or
combination becomes effective.


 


(c) Other
Events. If any event occurs of the type contemplated by the provisions of this Section 2 but not expressly provided for
by such provisions (including, without limitation, the granting of stock appreciation rights, phantom stock rights or other
rights with equity features), then the Company’s Board of Directors will make an appropriate adjustment in the Exercise
Price and the number of Warrant Shares, as mutually determined by the Company’s Board of Directors and the Required
Holders, so as to protect the rights of the Holder; provided that no such adjustment pursuant to this Section 2(c)
will increase the Exercise Price or decrease the number of Warrant Shares as otherwise determined pursuant to this Section
2.


 






    	 	- 6 -	 



    


    

 


3.
RIGHTS UPON DISTRIBUTION OF ASSETS. In addition to any adjustments pursuant to Section 2 above, if, on or after the Subscription
Date and on or prior to the Expiration Date, the Company shall declare or make any dividend or other distribution of its assets
(or rights to acquire its assets) to holders of shares of Common Stock, by way of return of capital or otherwise (including, without
limitation, any distribution of cash, stock or other securities, property, options, evidence of indebtedness or any other assets
by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction)
(a “Distribution”), at any time after the issuance of this Warrant, then, in each such case, the Holder shall
be entitled to participate in such Distribution to the same extent that the Holder would have participated therein if the Holder
had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant (without regard to any limitations
or restrictions on exercise of this Warrant, including without limitation, the Maximum Percentage) immediately before the date
of which a record is taken for such Distribution, or, if no such record is taken, the date as of which the record holders of shares
of Common Stock are to be determined for the participation in such Distribution (provided, however, that to the
extent that the Holder’s right to participate in any such Distribution would result in the Holder and the other Attribution
Parties exceeding the Maximum Percentage, then the Holder shall not be entitled to participate in such Distribution to such extent
(and shall not be entitled to beneficial ownership of such shares of Common Stock as a result of such Distribution (and beneficial
ownership) to such extent) and the portion of such Distribution shall be held in abeyance for the benefit of the Holder until
such time or times as its right thereto would not result in the Holder and the other Attribution Parties exceeding the Maximum
Percentage, at which time or times the Holder shall be granted such Distribution (and any Distributions declared or made on such
initial Distribution or on any subsequent Distribution held similarly in abeyance) to the same extent as if there had been no
such limitation).


 


4.
PURCHASE RIGHTS; FUNDAMENTAL TRANSACTIONS.


 


(a)Purchase
Rights. In addition to any adjustments pursuant to Section 2 above, if at any time on or after the Subscription Date and on
or prior to the Expiration Date the Company grants, issues or sells any Options, Convertible Securities or rights to purchase
stock, warrants, securities or other property pro rata to the record holders of any class of Common Stock (the “Purchase
Rights”), then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate
Purchase Rights which the Holder could have acquired if the Holder had held the number of shares of Common Stock acquirable upon
complete exercise of this Warrant (without regard to any limitations or restrictions on exercise of this Warrant, including without
limitation, the Maximum Percentage) immediately before the date on which a record is taken for the grant, issuance or sale of
such Purchase Rights, or, if no such record is taken, the date as of which the record holders of Common Stock are to be determined
for the grant, issuance or sale of such Purchase Rights (provided, however, that to the extent that the Holder’s
right to participate in any such Purchase Right would result in the Holder and the other Attribution Parties exceeding the Maximum
Percentage, then the Holder shall not be entitled to participate in such Purchase Right to such extent (and shall not be entitled
to beneficial ownership of such Common Stock as a result of such Purchase Right (and beneficial ownership) to such extent) and
such Purchase Right to such extent shall be held in abeyance for the benefit of the Holder until such time or times as its right
thereto would not result in the Holder and the other Attribution Parties exceeding the Maximum Percentage, at which time or times
the Holder shall be granted such right (and any Purchase Right granted, issued or sold on such initial Purchase Right or on any
subsequent Purchase Right to be held similarly in abeyance) to the same extent as if there had been no such limitation).


 






    	 	- 7 -	 



    


    

 


(b)The
Company shall not enter into or be party to a Fundamental Transaction unless the Successor Entity assumes in writing all of the
obligations of the Company under this Warrant in accordance with the provisions of this Section 4(b), including agreements to
deliver to the Holder in exchange for this Warrant a security of the Successor Entity evidenced by a written instrument substantially
similar in form and substance to this Warrant, including, without limitation, which is exercisable for a corresponding number
of shares of capital stock equivalent to the shares of Common Stock acquirable and receivable upon exercise of this Warrant (without
regard to any limitations on the exercise of this Warrant) prior to such Fundamental Transaction, and with an exercise price which
applies the exercise price hereunder to such shares of capital stock (but taking into account the relative value of the shares
of Common Stock pursuant to such Fundamental Transaction and the value of such shares of capital stock, such adjustments to the
number of shares of capital stock and such exercise price being for the purpose of protecting the economic value of this Warrant
immediately prior to the consummation of such Fundamental Transaction). Upon the consummation of each Fundamental Transaction,
the Successor Entity shall succeed to, and be substituted for (so that from and after the date of the applicable Fundamental Transaction,
the provisions of this Warrant and the other Transaction Documents referring to the “Company” shall refer instead
to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the
Company under this Warrant with the same effect as if such Successor Entity had been named as the Company herein. Upon consummation
of each Fundamental Transaction, the Successor Entity shall deliver to the Holder confirmation that there shall be issued upon
exercise of this Warrant at any time after the consummation of the applicable Fundamental Transaction, in lieu of the shares of
Common Stock (or other securities, cash, assets or other property (except such items still issuable under Sections 3 and 4(a)
above, which shall continue to be receivable thereafter)) issuable upon the exercise of this Warrant prior to the applicable Fundamental
Transaction, such shares of common stock (or its equivalent) of the Successor Entity (including its Parent Entity) which the Holder
would have been entitled to receive upon the happening of the applicable Fundamental Transaction had this Warrant been exercised
immediately prior to the applicable Fundamental Transaction (without regard to any limitations on the exercise of this Warrant),
as adjusted in accordance with the provisions of this Warrant. Notwithstanding the foregoing, and without limiting the provisions
of Section 1(f) hereof, the Holder may elect, at its sole option, by delivery of written notice to the Company to waive this Section
4(b) to permit the Fundamental Transaction without the assumption of this Warrant. In addition to and not in substitution for
any other rights hereunder, prior to the consummation of each Fundamental Transaction pursuant to which holders of shares of Common
Stock are entitled to receive securities or other assets with respect to or in exchange for shares of Common Stock (a “Corporate
Event”), the Company shall make appropriate provision to ensure that the Holder will thereafter have the right to receive
upon an exercise of this Warrant at any time after the consummation of the applicable Fundamental Transaction but prior to the
Expiration Date, in lieu of the shares of the Common Stock (or other securities, cash, assets or other property (except such items
still issuable under Sections 3 and 4(a) above, which shall continue to be receivable thereafter)) issuable upon the exercise
of the Warrant prior to such Fundamental Transaction, such shares of stock, securities, cash, assets or any other property whatsoever
(including warrants or other purchase or subscription rights) (collectively, the “Corporate Event Consideration”)
which the Holder would have been entitled to receive upon the happening of the applicable Fundamental Transaction had this Warrant
been exercised immediately prior to the applicable Fundamental Transaction (without regard to any limitations on the exercise
of this Warrant). The provision made pursuant to the preceding sentence shall be in a form and substance reasonably satisfactory
to the Holder.


 


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


 


6.
WARRANT HOLDER NOT DEEMED A STOCKHOLDER. Except as otherwise specifically provided herein, the Holder, solely in such Person’s
capacity as a holder of this Warrant, shall not be entitled to vote or receive dividends or be deemed the holder of capital stock
of the Company for any purpose, nor shall anything contained in this Warrant be construed to confer upon the Holder, solely in
such Person’s capacity as the Holder of this Warrant, any of the rights of a stockholder of the Company or any right to
vote, give or withhold consent to any corporate action (whether any reorganization, issue of stock, reclassification of stock,
consolidation, merger, conveyance or otherwise), receive notice of meetings, receive dividends or subscription rights, or otherwise,
prior to the issuance to the Holder of the Warrant Shares which such Person is then entitled to receive upon the due exercise
of this Warrant. In addition, nothing contained in this Warrant shall be construed as imposing any liabilities on the Holder to
purchase any securities (upon exercise of this Warrant or otherwise) or as a stockholder of the Company, whether such liabilities
are asserted by the Company or by creditors of the Company. Notwithstanding this Section 6, the Company shall provide the Holder
with copies of the same notices and other information given to the stockholders of the Company generally, contemporaneously with
the giving thereof to the stockholders.

7. REISSUANCE
OF WARRANTS.


 


(a)Transfer
of Warrant. If this Warrant is to be transferred, the Holder shall surrender this Warrant to the Company, whereupon the Company
will forthwith issue and deliver upon the order of the Holder a new Warrant (in accordance with Section 7(d)), registered as the
Holder may request, representing the right to purchase the number of Warrant Shares being transferred by the Holder and, if less
than the total number of Warrant Shares then underlying this Warrant is being transferred, a new Warrant (in accordance with Section
7(d)) to the Holder representing the right to purchase the number of Warrant Shares not being transferred.


 


(b)
Lost, Stolen or Mutilated Warrant. Upon receipt by the Company of evidence reasonably satisfactory to the Company of the
loss, theft, destruction or mutilation of this Warrant, and, in the case of loss, theft or destruction, of any indemnification
undertaking by the Holder to the Company in customary form (but without the obligation to post a bond) and, in the case of mutilation,
upon surrender and cancellation of this Warrant, the Company shall execute and deliver to the Holder a new Warrant (in accordance
with Section 7(d)) representing the right to purchase the Warrant Shares then underlying this Warrant.


 


(c) Exchangeable
for Multiple Warrants. This Warrant is exchangeable, upon the surrender hereof by the Holder at the principal office of
the Company, for a new Warrant or Warrants (in accordance with Section 7(d)) representing in the aggregate the right to
purchase the number of Warrant Shares then underlying this Warrant, and each such new Warrant will represent the right to
purchase such portion of such Warrant Shares as is designated by the Holder at the time of such surrender; provided, however,
that no Additional Warrants for fractional Warrant Shares shall be given.


 


(d)
Issuance of New Warrants. Whenever the Company is required to issue a new Warrant pursuant to the terms of this Warrant,
such new Warrant (i) shall be of like tenor with this Warrant, (ii) shall represent, as indicated on the face of such new Warrant,
the right to purchase the Warrant Shares then underlying this Warrant (or in the case of a new Warrant being issued pursuant to
Section 7(a) or Section 7(c), the Warrant Shares designated by the Holder which, when added to the number of shares of Common
Stock underlying the other new Warrants issued in connection with such issuance, does not exceed the number of Warrant Shares
then underlying this Warrant), (iii) shall have an issuance date, as indicated on the face of such new Warrant which is the same
as the Issuance Date, and (iv) shall have the same rights and conditions as this Warrant.


 


8. NOTICES.
Whenever notice is required to be given under this Warrant, unless otherwise provided herein, such notice shall be given in
writing, (i) if delivered (a) from within the domestic United States, by first-class registered or certified airmail, or
nationally recognized overnight express courier, postage prepaid, electronic mail or by facsimile or (b) from outside the

(ii)
if to the Holder, at such address or other contact information delivered by the Holder to Company or as is on the books and
records of the Company.


 


The
Company shall provide the Holder with prompt written notice of all actions taken pursuant to this Warrant, including in reasonable
detail a description of such action and the reason therefor. Without limiting the generality of the foregoing, the Company will
give written notice to the Holder (i) immediately upon any adjustment of the Exercise Price, setting forth in reasonable detail,
and certifying, the calculation of such adjustment and (ii) at least fifteen (15) days prior to the date on which the Company
closes its books or takes a record (A) with respect to any dividend or distribution upon the shares of Common Stock, (B) with
respect to any grants, issuances or sales of any Options, Convertible Securities or rights to purchase stock, warrants, securities

specified by the Holder in each Exercise Notice shall be definitive and may not be disputed or challenged by the Company.


 


9.
AMENDMENT AND WAIVER. Except as otherwise provided herein, the provisions of this Warrant may be amended or waived and
the Company may take any action herein prohibited, or omit to perform any act herein required to be performed by it, only if the
Company has obtained the written consent of the holder(s) of then-outstanding Additional Warrants exercisable for at least a majority
of the shares of Common Stock underlying such then-outstanding Additional Warrants.


 


10.
GOVERNING LAW; JURISDICTION; JURY TRIAL. This Warrant shall be governed by and construed and enforced in accordance with,
and all questions concerning the construction, validity, interpretation and performance of this Warrant shall be governed by,
the internal laws of the State of New York, without giving effect to any choice of law or conflict of law provision or rule (whether
of the State of New York or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than
the State of New York. The Company 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, and hereby irrevocably waives, and agrees not to assert in any suit,
action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action
or proceeding is brought in an inconvenient forum or that the venue of such suit, action or proceeding is improper. The Company
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 to the Company at the address set forth in Section 8(i) above or such other address as the Company subsequently
delivers to the Holder 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 manner permitted by law. Nothing
contained herein shall be deemed or operate to preclude the Holder from bringing suit or taking other legal action against the
Company in any other jurisdiction to collect on the Company’s obligations to the Holder, to realize on any collateral or
any other security for such obligations, or to enforce a judgment or other court ruling in favor of the Holder. THE COMPANY
HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER
OR IN CONNECTION WITH OR ARISING OUT OF THIS WARRANT OR ANY TRANSACTION CONTEMPLATED HEREBY.


 


11. DISPUTE
RESOLUTION. In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the
Warrant Shares, the Company shall submit the disputed determinations or arithmetic calculations via facsimile or electronic
mail within two (2) Business Days of receipt of the Exercise Notice or other event giving rise to such dispute, as the case
may be, to the Holder. If the Holder and the Company are unable to agree upon such determination or calculation of the
Exercise Price or the Warrant Shares within three (3) Business Days of such disputed determination or arithmetic calculation
being submitted to the Holder, then the Company shall, within two (2) Business Days submit via facsimile or electronic mail
(a) the disputed determination of the Exercise Price to an independent, reputable investment bank selected by the Company and
approved by the Holder or (b) the disputed arithmetic calculation of the Warrant Shares to the Company’s independent,
outside accountant. The Company shall cause at its expense the investment bank or the accountant, as the case may be, to
perform the determinations or calculations and notify the Company and the Holder of the results no later than ten (10)
Business Days from the time it receives the disputed determinations or calculations. Such investment bank’s or
accountant’s determination or calculation, as the case may be, shall be binding upon all parties absent demonstrable
error.

12. REMEDIES,
OTHER OBLIGATIONS, BREACHES AND INJUNCTIVE RELIEF. The remedies provided in this Warrant shall be cumulative and in
addition to all other remedies available under this Warrant and any other Transaction Documents, at law or in equity
(including a decree of specific performance and/or other injunctive relief), and nothing herein shall limit the right of the
Holder to pursue actual damages for any failure by the Company to comply with the terms of this Warrant. The Company
acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Holder and that the remedy
at law for any such breach may be inadequate. The Company therefore agrees that, in the event of any such breach or
threatened breach, the holder of this Warrant shall be entitled, in addition to all other available remedies, to an
injunction restraining any breach, without the necessity of showing economic loss and without any bond or other security
being required.


 


13. RESTRICTIONS
ON TRANSFER; LEGEND. This Warrant and the Warrant Shares may be offered for sale, sold, transferred, pledged or assigned
without the consent of the Company.


 


(a)
The Holder understands that (i) the Warrant and Warrant Shares have not been and are not being registered under the 1933 Act
or any state securities laws, and may not be offered for sale, sold, assigned or transferred unless (A) subsequently
registered thereunder, (B) the Holder shall have delivered to the Company an opinion of counsel, in a generally acceptable
form, to the effect that such Warrant or Warrant Shares to be sold, assigned or transferred may be sold, assigned or
transferred pursuant to an exemption from such registration, or (C) such Holder provides the Company with reasonable
assurance that such Warrant or Warrant Shares can be sold, assigned or transferred pursuant to Rule 144 or Rule 144A, as
promulgated under the 1933 Act and then in effect (or a successor rule thereto) (collectively, “Rule
144”); (ii) any sale of the Warrant or Warrant Shares made in reliance on Rule 144 may be made only in accordance
with the terms of Rule 144 and further, if Rule 144 is not applicable, any resale of the Securities under circumstances in
which the seller (or the Person) through whom the sale is made) may be deemed to be an underwriter (as that term is defined
in the 1933 Act) may require compliance with some other exemption under the 1933 Act or the rules and regulations of the SEC
thereunder; and (iii) neither the Company nor any other Person is under any obligation to register the Warrant or Warrant
Shares under the 1933 Act or any state securities laws or to comply with the terms and conditions of any

and no Holder effecting such a pledge shall be required to provide the Company with any notice thereof or otherwise make any
delivery to the Company pursuant to this Warrant.


 


(b)

with a sale, assignment or other transfer, such holder provides the Company with an opinion of counsel, in a generally acceptable
form, to the effect that such sale, assignment or transfer of the Warrant Shares may be made without registration under the applicable
requirements of the 1933 Act, or (iii) the Warrant Shares can be sold, assigned or transferred pursuant to Rule 144 or Rule 144A.
The Company shall be responsible for the fees of its transfer agent and all DTC fees associated with such issuance. If the Company

a certificate without such legend to the holder or to issue such Warrant Shares to such holder by electronic delivery at the applicable
balance account at DTC, and if on or after such Trading Day the holder purchases (in an open market transaction or otherwise)
shares of Common Stock to deliver in satisfaction of a sale by the holder of such Warrant Shares that the Holder anticipated receiving
without legend from the Company, then the Company shall, within three (3) Trading Days after the Holder’s request and in
the Holder’s discretion, either (i) pay cash to the Holder in an amount equal to the Holder’s total purchase price
(including brokerage commissions, if any) for the shares of Common Stock so purchased (the “Legend Buy-In Price”),
at which point the Company’s obligation to deliver such unlegended Warrant Shares shall terminate, or (ii) promptly honor
its obligation to deliver to the holder such unlegended Warrant Shares as provided above and pay cash to the Holder in an amount
equal to the excess (if any) of the Legend Buy-In Price over the product of (A) such number of shares of Common Stock, times
(B) the Closing Bid Price on the date of the occurrence of any of clauses (i) through (iii), as applicable. In addition, the Company
shall cause its legal counsel to issue a legal opinion to the Transfer Agent, if required by the Company or such Transfer Agent,
to effect the removal of the restrictive legends hereunder, at such time as the Warrant Shares may be sold pursuant to Rule 144
or an effective registration statement, provided that, with respect to legend removal in reliance upon the availability
of Rule 144, the Holder provides the Company and such legal counsel with such information as may be reasonably required by such
legal counsel that provides reasonable assurance that the Warrant Shares can be sold assigned or transferred pursuant to Rule
144 as of the date in question.


 


14. SEVERABILITY;
CONSTRUCTION; HEADINGS.If any provision of this Warrant
is prohibited by law or otherwise determined to be invalid or unenforceable by a court of competent jurisdiction, the provision
that would otherwise be prohibited, invalid or unenforceable shall be deemed amended to apply to the broadest extent that it would

provisions of this Warrant so long as this Warrant as so modified continues to express, without material change, the original
intentions of the parties as to the subject matter hereof and the prohibited nature, invalidity or unenforceability of the provision(s)
in question does not substantially impair the respective expectations or reciprocal obligations of the parties or the practical
realization of the benefits that would otherwise be conferred upon the parties. The parties will endeavor in good faith negotiations
to replace the prohibited, invalid or unenforceable provision(s) with a valid provision(s), the effect of which comes as close

Investor
Questionnaire


 


This
investor questionnaire is being submitted by the undersigned to Ener-Core, Inc., a Delaware corporation (“Issuer”)
in order to determine whether the undersigned qualifies as an “accredited investor” under Regulation D promulgated
under the Securities Act of 1933 (the “Securities Act”). The undersigned understands that Issuer will rely
upon the accuracy and completeness of the information provided in this questionnaire in determining whether certain issuances
of securities of Issuer may qualify for an exemption from the registration requirements of the Securities Act. Please return your
completed questionnaire and executed signature page hereto with your signature page to the Securities Purchase Agreement.


 


I.Accredited
Investor: The undersigned hereby represents and warrants that the undersigned is an “accredited investor” under
Regulation D promulgated under the Securities Act. ☐ (please check box if you are an accredited investor)


 


The
undersigned is an “accredited investor” for one of the following reasons (check whichever applies):


 


Individuals. If the undersigned
is a natural person (ignoring any revocable grantor trust), then the undersigned hereby represents and warrants as follows (check
whichever applies):


 


		☐	The
                                         undersigned is a director, executive officer, or general partner of the Issuer, or a
                                         director, executive officer, or general partner of a general partner of the Issuer.
	 	 	 
		☐	The
                                         undersigned has a net worth (either individually or jointly with the undersigned’s
                                         spouse) in excess of $1,000,000 (see calculation guidance below).
	 	 	 
		☐	The
                                         undersigned (i) either (A) had an individual annual income (exclusive of spousal income)
                                         in excess of $200,000 or (B) had a joint income with the undersigned’s spouse in
                                         excess of $300,000 in each of the two preceding tax years, and (ii) reasonably expects
                                         to have the same income level (individually or jointly, as applicable) in the current
                                         tax year (see calculation guidance below).



 


The
term “net worth” means the excess of total assets over total liabilities. In calculating “net worth,”
the Investor must exclude the value of the Investor’s principal residence as an asset. The value of the principal residence
should be calculated as the fair market value of the residence, less any debt secured by such residence. To the extent that the
amount of debt secured by the primary residence exceeds the fair market value of such residence, this excess amount of debt should
be considered a liability for purposes of calculating net worth. The term “individual income” means
adjusted gross income, as reported for federal income tax purposes, less any income attributable to a spouse or property owned
by a spouse, increased by the amount (if not attributable to a spouse or property owned by a spouse) of any tax-exempt shares
received, losses claimed as a partner in an entity treated as a partnership for tax purposes, any deduction claimed for depletion,
any deduction for long term capital gains. The term “joint income” is defined in the same manner as “individual
income,” except that income attributable to a spouse or property owned by a spouse is included.


 


Trusts.
If the undersigned is a trust, then the undersigned hereby represents and warrants that the undersigned is (check whichever
applies):


 


		☐	A
                                         revocable trust (such as a living trust) or a trust formed for the purpose of acquiring
                                         the securities and for which, in either case, each grantor is an accredited investor.
                                         Indicate each grantor and the category that describes how each such grantor itself is

This
letter shall serve as our irrevocable authorization and direction to you (provided that you are the transfer agent of the Company
at such time):


 


(i)to
issue shares of Common Stock upon conversion of the Notes (the “Conversion Shares”) to or upon the order
of a Holder from time to time upon delivery to you of a properly completed and duly executed Conversion Notice, in the form attached
hereto as Exhibit I, which has been acknowledged by the Company as indicated by the signature of a duly authorized officer
of the Company thereon; and


 


(ii)to

(Litigation)


 


On
June 13, 2016, SAIL Venture Partners LLC, SAIL Capital Management LLC and all SAIL affiliates owning shares of the Company (collectively,
“SAIL”) filed a Schedule 13D in which it set forth various complaints and demands with respect to the Company
(EDGAR Link). The Company has disputed all such complaints and demands.


 


Schedule
3(aa)


(Internal
Accounting and Disclosure Controls)


 


As
of December 31, 2015, the Company’s management, under the supervision and with the participation of its Chief Executive
Officer and Chief Financial Officer, performed an evaluation of the effectiveness of its disclosure controls and procedures (as
defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended).


 


Based
on such evaluation, the disclosure controls and procedures of the Company and the Subsidiary as of December 31, 2015 were ineffective
at the reasonable assurance level due to the following material weaknesses in internal control over financial reporting:


 


		1.	We
                                         do not have written documentation of our internal control policies and procedures. Management
                                         evaluated the impact of our failure to have written documentation of our internal controls
                                         and procedures on our assessment of our disclosure controls and procedures and has concluded
                                         that the control deficiency that resulted represented a material weakness.



 


		2.	We
                                         do not have sufficient segregation of duties within accounting functions, which is a
                                         basic internal control. Due to our size and nature, segregation of all conflicting duties
                                         may not always be possible and may not be economically feasible. However, to the extent
                                         possible, the initiation of transactions, the custody of assets and the recording of
                                         transactions should be performed by separate individuals. Management evaluated the impact
                                         of our failure to have segregation of duties on our assessment of our disclosure controls
                                         and procedures and has concluded that the control deficiency that resulted represented
                                         a material weakness.



 


		3.	For
                                         the year ending December 31, 2015, we did not have a sufficient, integrated purchasing
                                         and accounting system to allow for proper tracking, control and costing of our prototype
                                         KG2 Powerstation costs carried as a fixed asset and Powerstations currently under construction
                                         for sale and carried in inventory. Although we believe that our costing is accurate,
                                         based on additional review and procedures, to the extent we sell additional units, we
                                         will need to enhance our controls over our inventory systems. Management evaluated the
                                         impact of our failure to have adequate inventory accounting systems, coupled with the
                                         risk associated with costing our inventory, and the expected future activity for our
                                         inventory costing system and has concluded that the control deficiency that resulted
                                         represented a material weakness.



 


		4.	For
                                         the year ending December 31, 2014 we did not have a majority of our Directors considered
                                         to be independent Directors. Until December 1, 2014, we had a majority of our Board of
                                         Directors considered to be not independent. Between December 1, 2014 and May 18, 2015
                                         our Board was split evenly between independent Directors and non-independent Directors.
                                         Management evaluated the impact of our failure to have a fully independent Board of Directors,
                                         on our assessment of our disclosure controls and procedures and has concluded that the
                                         control deficiency that resulted represented a material weakness.

		5.	For
                                         the year ending December 31, 2014 and until July 2015, our Audit Committee consisted
                                         of the Chairman of the committee only. Until July 2015 we did not have a formal Compensation
                                         Committee or Nominating and Corporate Governance Committee. Management evaluated the
                                         impact of our failure to have an adequate Audit Committee and an internal audit function
                                         on our assessment of our disclosure controls and procedures and has concluded that the
                                         control deficiency that resulted represented a material weakness.



 


		6.	For
                                         the year ending December 31, 2015, management concluded that the Company’s management
                                         information systems and information technology internal control design was deficient
                                         because the potential for unauthorized access to certain information systems and software
                                         applications existed during 2015 in several departments, including corporate accounting.
                                         Additionally, certain key controls for maintaining the overall integrity of systems and
                                         data processing were not properly designed and operating effectively. These deficiencies
                                         increased the likelihood of potential material errors in our financial reporting. Management
                                         evaluated the impact of our failure to have adequate information technology controls,
                                         on our assessment of our disclosure controls and procedures and has concluded that the
                                         control deficiency that resulted represented a material weakness.



 


As
of June 30, 2016, the Company’s management, under the supervision and with the participation of its Chief Executive Officer
and Chief Financial Officer, performed an evaluation of the effectiveness of its disclosure controls and procedures (as defined
in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended). Based on the evaluation, the Company’s
Chief Executive Officer and Chief Financial Officer concluded that, as of June 30, 2016, the Company’s disclosure controls
and procedures were ineffective at the reasonable assurance level. Such conclusion is due to the presence of material weaknesses
in internal control over financial reporting. The Company’s management anticipates that its disclosure controls and procedures
will remain ineffective until such material weaknesses are remediated.
