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

3.REPRESENTATIONS
AND WARRANTIES OF THE COMPANY.


 


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


 


(a)Organization
and Qualification. Each of the Company and its “Subsidiaries” (which for purposes of this Agreement means

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

to perform its obligations under the Transaction Documents. The Company has no Subsidiaries except as set forth on Schedule

the SEC of a Form D and any other 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. Each of the Subsidiaries party to any of the Transaction
Documents has the requisite power and authority to enter into and perform its obligations under such Transaction Documents., as
applicable The execution and delivery by the Subsidiaries party to any of the Transaction Documents of such Transaction Documents
and the consummation by such Subsidiaries of the transactions contemplated thereby have been duly authorized by such Subsidiaries’

agencies) no further filing, consent, or authorization is required by such Subsidiaries, their respective boards of directors
(or other applicable governing body) or stockholders (or other applicable owners of equity of such Subsidiaries). The Transaction
Documents to which any of the Subsidiaries are parties have been duly executed and delivered by such Subsidiaries, and constitute
the legal, valid and binding obligations of such Subsidiaries, enforceable against them 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.

of Common Stock shall have been duly authorized and reserved for issuance which equals or exceeds (the “Required Reserved
Amount) the sum of (i) the maximum number of Conversion Shares issued and issuable pursuant to the Notes to be issued in such
Closing based on the initial Conversion Price (as defined in the Notes) of $2.50 (as adjusted for any stock dividend, stock split,

limitations on the issuance thereof pursuant to the terms of the Notes) (the “Initial Conversion Price”) plus
(ii) the maximum number of Warrant Shares issued and issuable pursuant to the Warrants to be issued in such Closing, each as of

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,

securities agencies), 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. All consents, authorizations, orders, filings and registrations which the Company
or any of its Subsidiaries is required to obtain pursuant to the preceding sentence have been obtained or effected on or prior
to the Initial Closing Date, and the Company and its Subsidiaries are unaware of any facts or circumstances that might prevent
the Company or any of its Subsidiaries from obtaining or effecting any of the registration, application or filings pursuant to
the preceding sentence. The Company is not in violation of the listing 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.

or obligations of others of the kinds referred to in clauses (A) through (G) above; and (y) “Contingent Obligation”

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.

(s)Absence
of 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 Company or any of its Subsidiaries, the Common Stock or any of the Company’s Subsidiaries or any
of the Company’s 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(s). The matters set forth in Schedule 3(s) would not

(t)Insurance.
The Company and each of its Subsidiaries are insured by insurers of recognized financial responsibility against such losses and
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.


 


(u)Employee
Relations.


 


(i)

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.




 






    	 	- 16 - 	 



     


    

 


(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

Adverse Effect.




 


(v)Title.
The Company and its Subsidiaries have good and marketable title in fee simple to all real property and good and marketable title
to all personal property owned by them which is material to the business of the Company and its Subsidiaries, in each case free
and clear of all liens, encumbrances and defects except for Permitted Liens which do not materially affect the value of such property
and do not interfere with the use made and proposed to be made of such property by the Company and any of its Subsidiaries. Any
real property and facilities held under lease by the Company and any of its Subsidiaries are held by them under valid, subsisting
and enforceable leases with such exceptions as are not material and do not interfere with the use made and proposed to be made
of such property and buildings by the Company and its Subsidiaries.


 


(w)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 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,

no basis for any such claim.


 


(bb)Internal
Accounting and Disclosure Controls. Except as set forth in Schedule 3(bb) or as set forth in the SEC Documents, the
Company and each of its Subsidiaries maintain a system of internal accounting controls sufficient to provide reasonable assurance

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” transaction. The Company further understands and acknowledges that one or

or any of the documents executed in connection herewith.

representations in effecting transactions in securities of the Company. All disclosure provided to the Buyers regarding the Company,
or any of its Subsidiaries, their business and the transactions contemplated hereby, including the disclosure schedules to this
Agreement, furnished by or on behalf of the Company is true and correct and does not contain any untrue statement of a material
fact or omit to state any material fact necessary in order to make the statements made therein, in the light of the circumstances
under which they were made, not misleading. Each press release issued by the Company or any of its Subsidiaries during the twelve

or omit 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. No event or circumstance has occurred or information exists with
respect to the Company or any of its Subsidiaries or its or their business, properties, prospects, operations or financial conditions,
which, under applicable law, rule or regulation, requires public disclosure or announcement by the Company but which has not been
so publicly announced or disclosed. The Company acknowledges and agrees that no Buyer makes or has made any representations or
warranties with respect to the transactions contemplated hereby other than those specifically set forth in Section 2.

9.MISCELLANEOUS.


 


(a)Governing
Law; Jurisdiction; Jury Trial. All questions concerning the construction, validity, enforcement and interpretation of this
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 may be executed in two or more identical counterparts, all of which shall be considered one and the same agreement
and shall become effective when counterparts have been signed by each party and delivered to the other party; provided that a
facsimile or “.pdf” electronic format signature shall be considered due execution and shall be binding upon the signatory
thereto with the same force and effect as if the signature were an original, not a facsimile or “.pdf” electronic
format signature.


 


(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.


 


(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).


 






    	 	- 35 - 	 



     


    

 


(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 Initial Conversion
Price) and Warrants (without regard to any limitation on conversion or exercise set forth therein) and shall include Empery so
long as Empery or any of its affiliates holds any Securities (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; provided, further, that the provisions of Section 4(q) cannot be amended
without the additional prior written approval of the Collateral Agent or its successor. Any amendment or waiver effected in accordance
with this Section 9(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.

(g)Successors
and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their respective successors

or obligations hereunder without the prior written consent of the Required Holders, including by way of a Fundamental Transaction
(unless the Company is in compliance with the applicable provisions governing Fundamental Transactions set forth in the Notes
and the Warrants). A Buyer may assign some or all of its rights hereunder without the consent of the Company, in which event such

(i)Survival.

    	 	- 38 - 	 



     


    

 


(j)Further
Assurances. Each party shall do and perform, or cause to be done and performed, all such further acts and things, and shall
execute and deliver all such other agreements, certificates, instruments and documents, as any other party may reasonably request
in order to carry out the intent and accomplish the purposes of this Agreement and the consummation of the transactions contemplated
hereby, including without limitation taking such reasonable action as is necessary or desirable to perfect a security interest
in the Company’s or one or more of its Subsidiaries’ Intellectual Property. Also, without limiting the generality
of the requirements of the Company set forth in the Transaction Documents, the Company hereby covenants and agrees to provide
prompt notice to the Collateral Agent upon the issuance of any patents in the name of the Company or any of their Subsidiaries
anywhere in the world.


 


(k)Indemnification.
In consideration of each Buyer’s execution and delivery of the Transaction Documents and acquiring the Securities thereunder
and in addition to all of the Company’s other obligations under the Transaction Documents, the Company shall defend, protect,
indemnify and hold harmless each Buyer and each other holder of the Securities and all of their stockholders, partners, members,
officers, directors, employees and direct or indirect investors and any of the foregoing Persons’ agents or other representatives
(including, without limitation, those retained in connection with the transactions contemplated by this Agreement) (collectively,
the “Indemnitees”) from and against any and all actions, causes of action, suits, claims, losses, costs, penalties,
fees, liabilities and damages, and expenses in connection therewith (irrespective of whether any such Indemnitee is a party to
the action for which indemnification hereunder is sought), and including reasonable attorneys’ fees and disbursements (the
“Indemnified Liabilities”), incurred by any Indemnitee as a result of, or arising out of, or relating to (a)
any misrepresentation or breach of any representation or warranty made by the Company in the Transaction Documents or any other
certificate, instrument or document contemplated hereby or thereby, (b) any breach of any covenant, agreement or obligation of
the Company contained in the Transaction Documents or any other certificate, instrument or document contemplated hereby or thereby
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, (iii) any disclosure made by such Buyer pursuant to Section 4(j), or (iv) 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. 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. Except as otherwise
set forth herein, the mechanics and procedures with respect to the rights and obligations under this Section 9(k) shall be the
same as those set forth in Section 6 of the Registration Rights Agreement.


 






    	 	- 39 - 	 



     


    

 


(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

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.

GUARANTY


 


GUARANTY,
dated as of November 23, 2016, made by each of the undersigned (each a “Guarantor”, and collectively, the “Guarantors”),
in favor of the “Buyers” (as defined below) party to the Securities Purchase Agreement referenced below.


 


W
I T N E S S E T H :


 


WHEREAS,
Ener-Core, Inc., a Delaware corporation (the ”Company”), each party listed as a “Buyer” on
the Schedule of Buyers attached to the Securities Purchase Agreement and each “Subsequent Buyer”, if any, that is
party to a joinder agreement with respect to the Securities Purchase Agreement (each a “Buyer”, and collectively,
the “Buyers”) are parties to that certain Securities Purchase Agreement, dated as of November 23, 2016 (the
“Securities Purchase Agreement”), pursuant to which, among other things, the Buyers shall purchase from the
Company certain senior secured convertible “Notes” (as defined in the Securities Purchase Agreement) (collectively,
the “Notes”);


 


WHEREAS,
the Buyers have requested, and the Guarantors have agreed, that the Guarantors shall execute and deliver to the Buyers, a guaranty
guaranteeing all of the obligations of the Company under the Securities Purchase Agreement, the Notes and the other “Transaction
Documents” (as defined in the Securities Purchase Agreement, the “Transaction Documents”);


 


WHEREAS,
pursuant to a Pledge and Security Agreement, dated as of April 22, 2015 (as the same has been, and may be, amended from time to
time, the “Security Agreement”), the Company and the Guarantors have granted to Empery Tax Efficient, LP, as
collateral agent for the Buyers (in such capacity, the “Collateral Agent”), a security interest in and lien
on selected assets to secure their respective obligations under this Guaranty, the Securities Purchase Agreement, the Notes and
the other Transaction Documents; and


 


WHEREAS,
each Guarantor has determined that the execution, delivery and performance of this Guaranty directly benefits, and is in the best
interest of, such Guarantor.


 


NOW,
THEREFORE, in consideration of the premises and the agreements herein and for other consideration, the sufficiency of which is
hereby acknowledged, each Guarantor hereby agrees with each Buyer as follows:


 


1. Definitions.
Reference is hereby made to the Securities Purchase Agreement and the Notes for a statement of the terms thereof. All terms used
in this Guaranty, which are defined in the Securities Purchase Agreement or the Notes and not otherwise defined herein, shall
have the same meanings herein as set forth therein.


 


2. Guaranty.
The Guarantors, jointly and severally, hereby unconditionally and irrevocably, guaranty (a) the punctual payment, as and when
due and payable, by stated maturity or otherwise, of all obligations and any other amounts now or hereafter owing by the Company
in respect of the Securities Purchase Agreement, the Notes and the other Transaction Documents, including, without limitation,
all interest that accrues after the commencement of any proceeding commenced by or against any the Company or any Guarantor under
any provision of the Bankruptcy Code (Chapter 11 of Title 11 of the United States Code) or under any other bankruptcy or
insolvency law, assignments for the benefit of creditors, formal or informal moratoria, compositions, or extensions generally
with creditors, or proceedings seeking reorganization, arrangement, or other similar relief (an “Insolvency Proceeding”),
whether or not the payment of such interest is unenforceable or is not allowable due to the existence of such Insolvency Proceeding,
and all fees, commissions, expense reimbursements, indemnifications and all other amounts due or to become due under any of the
Transaction Documents, and any and all expenses (including reasonable counsel fees and expenses) reasonably incurred by the Buyers
or the Collateral Agent in enforcing any rights under this Guaranty (such obligations, to the extent not paid by the Company,
being the “Guaranteed Obligations”) and (b) the punctual and faithful performance, keeping, observance and
fulfillment by the Company of all of the agreements, conditions, covenants and obligations of the Company contained in the Securities
Purchase Agreement, the Notes and the other Transaction Documents. Without limiting the generality of the foregoing, each Guarantor’s
liability hereunder shall extend to all amounts that constitute part of the Guaranteed Obligations and would be owed by the Company
to the Buyers under the Securities Purchase Agreement and the Notes but for the fact that they are unenforceable or not allowable
due to the existence of an Insolvency Proceeding involving any Guarantor or the Company (each, a “Transaction Party”).


 






     

     


    

 


3. Guaranty
Absolute; Continuing Guaranty; Assignments.


 


(a) The
Guarantors, jointly and severally, guaranty that the Guaranteed Obligations will be paid strictly in accordance with the terms
of the Transaction Documents, regardless of any law, regulation or order now or hereafter in effect in any jurisdiction affecting
any of such terms or the rights of the Buyers with respect thereto. The obligations of each Guarantor under this Guaranty are
independent of the Guaranteed Obligations, and a separate action or actions may be brought and prosecuted against any Guarantor
to enforce such obligations, irrespective of whether any action is brought against any Transaction Party or whether any Transaction
Party is joined in any such action or actions. The liability of any Guarantor under this Guaranty shall be irrevocable, absolute
and unconditional irrespective of, and each Guarantor hereby irrevocably waives, to the extent permitted by law, any defenses
it may now or hereafter have in any way relating to, any or all of the following:


 


(i)
any lack of validity or enforceability of any Transaction Document or any agreement or instrument relating thereto;


 


(ii) any
change in the time, manner or place of payment of, or in any other term of, all or any of the Guaranteed Obligations, or any other
amendment or waiver of or any consent to departure from any Transaction Document, including, without limitation, any increase
in the Guaranteed Obligations resulting from the extension of additional credit to any Transaction Party or otherwise;


 


(iii) any
taking, exchange, release or non-perfection of any collateral with respect to the Guaranteed Obligations, or any taking, release
or amendment or waiver of or consent to departure from any other guaranty, for all or any of the Guaranteed Obligations; or


 


(iv) any
change, restructuring or termination of the corporate, limited liability company or partnership structure or existence of any
Transaction Party.


 






    	 	- 2 -	 



     


    

 


This
Guaranty shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of the Guaranteed
Obligations is rescinded or must otherwise be returned by any Buyer or any other Person upon the insolvency, bankruptcy or reorganization
of any Transaction Party or otherwise, all as though such payment had not been made.


 


(b)
This Guaranty is a continuing guaranty and shall (i) remain in full force and effect until the complete conversion of all of the
Company’s obligations under the Notes to equity securities of the Company and/or indefeasible payment in full in cash of
all obligations under the Notes (together with any matured indemnification obligations as of the date of such conversion and/or
payment, but excluding any inchoate or unmatured contingent indemnification obligations) and payment of all other amounts payable
under this Guaranty (excluding any inchoate or unmatured contingent indemnification obligations) and (ii) be binding upon each
Guarantor and its respective successors and assigns. This Guaranty shall inure to the benefit of and be enforceable by the Buyers
and their respective successors, and permitted pledgees, transferees and assigns. Without limiting the generality of the foregoing
sentence, any Buyer may pledge, assign or otherwise transfer all or any portion of its rights and obligations under and subject
to the terms of any Transaction Document to any other Person, and such other Person shall thereupon become vested with all the
benefits in respect thereof granted to such Buyer herein or otherwise, in each case as provided in the Securities Purchase Agreement
or such Transaction Document. Notwithstanding the foregoing and for the avoidance of doubt, this Guaranty will expire and each
Guarantor will be released from its obligation hereunder upon the complete conversion of all of the Company’s obligations
under the Notes to equity securities of the Company and/or indefeasible payment in full in cash of all obligations under the Notes
(together with any matured indemnification obligations as of the date of such conversion and/or payment, but excluding any inchoate
or unmatured contingent indemnification obligations) and payment of all other amounts payable under this Guaranty (excluding any
inchoate or unmatured contingent indemnification obligations).


 


4. Waivers.
To the extent permitted by applicable law, each Guarantor hereby waives promptness, diligence, notice of acceptance and any other
notice with respect to any of the Guaranteed Obligations and this Guaranty and any requirement that the Buyers or the Collateral
Agent exhaust any right or take any action against any Transaction Party or any other Person or any Collateral (as defined in
the Security Agreement). Each Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements
contemplated herein and that the waiver set forth in this Section 4 is knowingly made in contemplation of such benefits.
The Guarantors hereby waive any right to revoke this Guaranty, and acknowledge that this Guaranty is continuing in nature and
applies to all Guaranteed Obligations, whether existing now or in the future.


 


5. Subrogation.
No Guarantor may exercise any rights that it may now or hereafter acquire against any Transaction Party or any other guarantor
that arise from the existence, payment, performance or enforcement of any Guarantor’s obligations under this Guaranty, including,
without limitation, any right of subrogation, reimbursement, exoneration, contribution or indemnification and any right to participate
in any claim or remedy of the Buyers or the Collateral Agent against any Transaction Party or any other guarantor or any Collateral
(as defined in the Security Agreement), whether or not such claim, remedy or right arises in equity or under contract, statute
or common law, including, without limitation, the right to take or receive from any Transaction Party or any other guarantor,
directly or indirectly, in cash or other property or by set-off or in any other manner, payment or security solely on account
of such claim, remedy or right, unless and until the complete conversion of all of the Company’s obligations under the Notes
to equity securities of the Company and/or indefeasible payment in full in cash of all obligations under the Notes (together with
any matured indemnification obligations as of the date of such conversion and/or payment, but excluding any inchoate or unmatured
contingent indemnification obligations) and payment of all other amounts payable under this Guaranty (excluding any inchoate or
unmatured contingent indemnification obligations). If any amount shall be paid to a Guarantor in violation of the immediately
preceding sentence at any time prior to the later of the payment in full in cash of the Guaranteed Obligations and all other amounts
payable under this Guaranty, such amount shall be held in trust for the benefit of the Buyers and shall forthwith be paid ratably
to the Buyers to be credited and applied to the Guaranteed Obligations and all other amounts payable under this Guaranty, whether
matured or unmatured, in accordance with the terms of the Transaction Documents, or to be held as collateral for any Guaranteed
Obligations or other amounts payable under this Guaranty thereafter arising. If (a) any Guarantor shall make payment to the
Buyers of all or any part of the Guaranteed Obligations, and (b) the Buyers receive the complete conversion of all of the
Company’s obligations under the Notes to equity securities of the Company and/or indefeasible payment in full in cash of
all obligations under the Notes (together with any matured indemnification obligations as of the date of such conversion and/or
payment, but excluding any inchoate or unmatured contingent indemnification obligations) and payment of all other amounts payable
under this Guaranty (excluding any inchoate or unmatured contingent indemnification obligations), the Buyers will, at such Guarantor’s
request and expense, execute and deliver to such Guarantor appropriate documents, without recourse and without representation
or warranty, necessary to evidence the transfer by subrogation to such Guarantor of an interest in the Guaranteed Obligations
resulting from such payment by such Guarantor.

good standing under the laws of the jurisdiction of its organization as set forth on the signature pages hereto, (B) has all requisite
corporate, limited liability company or limited partnership power and authority to conduct its business as now conducted and as
presently contemplated and to execute and deliver this Guaranty and each other Transaction Document to which the Guarantor is
a party, and to consummate the transactions contemplated hereby and thereby and (C) is duly qualified to do business and is in
good standing in each jurisdiction in which the character of the properties owned or leased by it or in which the transaction
of its business makes such qualification necessary except where the failure to be so qualified would not result in a Material
Adverse Effect.


 


(ii)
The execution, delivery and performance by each Guarantor of this Guaranty and each other Transaction Document to which such Guarantor
is a party (A) have been duly authorized by all necessary corporate, limited liability company or limited partnership action,
(B) do not and will not contravene its charter or by-laws, its limited liability company or operating agreement or its certificate
of partnership or partnership agreement, as applicable, or any applicable law or any contractual restriction binding on the Guarantor
or its properties do not and will not result in or require the creation of any lien (other than pursuant to any Transaction Document)
upon or with respect to any of its properties, and (C) do not and will not result in any default, noncompliance, suspension, revocation,
impairment, forfeiture or nonrenewal of any material permit, license, authorization or approval applicable to it or its operations
or any of its properties.


 






    	 	- 4 -	 



     


    

 


(iii)
No authorization or approval or other action by, and no notice to or filing with, any governmental authority is required in connection
with the due execution, delivery and performance by the Guarantor of this Guaranty or any of the other Transaction Documents to
which the Guarantor is a party (other than expressly provided for in any of the Transaction Documents).


 


(iv)
Each of this Guaranty and the other Transaction Documents to which the Guarantor is or will be a party, when delivered, will be,
a legal, valid and binding obligation of the Guarantor, enforceable against the Guarantor in accordance with its terms, except
as may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance, suretyship or other
similar laws and equitable principles (regardless of whether enforcement is sought in equity or at law).


 


(v)
There is no pending or, to the best knowledge of the Guarantor, threatened action, suit or proceeding against the Guarantor or
to which any of the properties of the Guarantor is subject, before any court or other governmental authority or any arbitrator
that (A) if adversely determined, could reasonably be expected to have a Material Adverse Effect or (B) relates to this
Guaranty or any of the other Transaction Documents to which the Guarantor is a party or any transaction contemplated hereby or
thereby.


 


(vi)
The Guarantor (A) has read and understands the terms and conditions of the Securities Purchase Agreement, the Notes and the other
Transaction Documents, and (B) now has and will continue to have independent means of obtaining information concerning the
affairs, financial condition and business of the Company and the other Transaction Parties, and has no need of, or right to obtain
from the Collateral Agent or any Buyer, any credit or other information concerning the affairs, financial condition or business
of the Company or the other Transaction Parties that may come under the control of the Collateral Agent or any Buyer.


 


(b)
The Guarantor covenants and agrees that until the complete conversion of all of the Company’s obligations under the Notes
to equity securities of the Company and/or indefeasible payment in full in cash of all obligations under the Notes (together with
any matured indemnification obligations as of the date of such conversion and/or payment, but excluding any inchoate or unmatured
contingent indemnification obligations) and payment of all other amounts payable under this Guaranty (excluding any inchoate or
unmatured contingent indemnification obligations), it will comply with each of the covenants (except to the extent applicable
only to a public company) which are set forth in Section 4 of the Securities Purchase Agreement as if the Guarantor
were a party thereto.


 






    	 	- 5 -	 



     


    

 


7. Right
of Set-off. Upon the occurrence and during the continuance of any Event of Default, the Collateral Agent and any Buyer
may, and is hereby authorized to, at any time and from time to time, without notice to the Guarantors (any such notice being expressly
waived by each Guarantor) and to the fullest extent permitted by law, set-off and apply any and all deposits (general or special,
time or demand, provisional or final) at any time held and other indebtedness at any time owing by any Buyer to or for the credit
or the account of any Guarantor against any and all obligations of the Guarantors now or hereafter existing under this Guaranty
or any other Transaction Document, irrespective of whether or not Collateral Agent or any Buyer shall have made any demand under
this Guaranty or any other Transaction Document and although such obligations may be contingent or unmatured. Collateral Agent
and each Buyer agrees to notify the relevant Guarantor promptly after any such set-off and application made by such Buyer, provided
that the failure to give such notice shall not affect the validity of such set-off and application. The rights of the Collateral
Agent or any Buyer under this Section 7 are in addition to other rights and remedies (including, without limitation,
other rights of set-off) which the Collateral Agent or such Buyer may have under this Guaranty or any other Transaction Document
in law or otherwise.

DOCUMENT MAY BE BROUGHT IN THE COURTS OF THE STATE OF NEW YORK IN THE COUNTY OF NEW YORK OR OF THE UNITED STATES DISTRICT COURT

WAIVER OF JURY TRIAL, ETC. EACH GUARANTOR HEREBY WAIVES ANY RIGHT TO A TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM
CONCERNING ANY RIGHTS UNDER THIS GUARANTY OR THE OTHER TRANSACTION DOCUMENTS, OR UNDER ANY AMENDMENT, WAIVER, CONSENT, INSTRUMENT,
DOCUMENT OR OTHER AGREEMENT DELIVERED OR WHICH IN THE FUTURE MAY BE DELIVERED IN CONNECTION HEREWITH OR THEREWITH, OR ARISING
FROM ANY FINANCING RELATIONSHIP EXISTING IN CONNECTION WITH THIS GUARANTY OR THE OTHER TRANSACTION DOCUMENTS, AND AGREES THAT

THAT THIS PROVISION IS A MATERIAL INDUCEMENT FOR THE BUYERS ENTERING INTO THE OTHER TRANSACTION DOCUMENTS.


 


11.
Taxes.


 


(a)
All payments made by any Guarantor hereunder or under any other Transaction Document shall be made in accordance with the terms
of the respective Transaction Document and shall be made without set-off, counterclaim, deduction or other defense. All such payments
shall be made free and clear of and without deduction for any present or future taxes, levies, imposts, deductions, charges or
withholdings, and all liabilities with respect thereto, excluding taxes imposed on the net income of any Buyer by the jurisdiction
in which such Buyer is organized or where it has its principal lending office (all such nonexcluded taxes, levies, imposts, deductions,
charges, withholdings and liabilities, collectively or individually, “Taxes”). If any Guarantor shall be required
to deduct or to withhold any Taxes from or in respect of any amount payable hereunder or under any other Transaction Document:


 


(i)
the amount so payable shall be increased to the extent necessary so that after making all required deductions and withholdings
(including Taxes on amounts payable to any Buyer pursuant to this sentence) each Buyer receives an amount equal to the sum it
would have received had no such deduction or withholding been made,


 






    	 	- 7 -	 



     


    

 


(ii)
such Guarantor shall make such deduction or withholding,


 


(iii)
such Guarantor shall pay the full amount deducted or withheld to the relevant taxation authority in accordance with applicable
law, and


 


(iv) as
promptly as possible thereafter, such Guarantor shall send the Buyers an official receipt (or, if an official receipt is not available,
such other documentation as shall be satisfactory to the Buyers, as the case may be) showing payment.  In addition, each
Guarantor agrees to pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar
levies that arise from any payment made hereunder or from the execution, delivery, registration or enforcement of, or otherwise
with respect to, this Agreement or any other Transaction Document (collectively, “Other Taxes”).


 


(b)
Each Guarantor hereby indemnifies and agrees to hold the Collateral Agent and each Buyer (each an “Indemnified Party”)
harmless from and against Taxes or Other Taxes (including, without limitation, any Taxes or Other Taxes imposed by any jurisdiction
on amounts payable under this Section 11) paid by any Indemnified Party  as a result of any payment made hereunder
or from the execution, delivery, registration or enforcement of, or otherwise with respect to, this Agreement or any other Transaction
Document, and any liability (including penalties, interest and expenses for nonpayment, late payment or otherwise) arising therefrom
or with respect thereto, whether or not such Taxes or Other Taxes were correctly or legally asserted.  This indemnification
shall be paid within 30 days from the date on which such Buyer makes written demand therefor, which demand shall identify the
nature and amount of such Taxes or Other Taxes.


 


(c) If
any Guarantor fails to perform any of its obligations under this Section 11, such Guarantor shall indemnify the Collateral
Agent and each Buyer for any taxes, interest or penalties that may become payable as a result of any such failure. The obligations
of the Guarantors under this Section 11 shall survive the termination of this Guaranty and the payment of the Obligations
and all other amounts payable hereunder.


 


12.
Miscellaneous.


 


(a)
Each Guarantor will make each payment hereunder in lawful money of the United States of America and in immediately available funds
to each Buyer, at such address specified by such Buyer from time to time by notice to the Guarantors.


 


(b)
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 Required Holders (as defined
in the Securities Purchase Agreement). Any amendment or waiver effected in accordance with this Section 12 shall be binding upon
each Buyer and holder of Securities and the Company.


 






    	 	- 8 -	 



     


    

 


(c)
No failure on the part of the Collateral Agent or any Buyer to exercise, and no delay in exercising, any right hereunder or under
any other Transaction Document shall operate as a waiver thereof, nor shall any single or partial exercise of any right hereunder
or under any Transaction Document preclude any other or further exercise thereof or the exercise of any other right. The rights
and remedies of the Collateral Agent and the Buyers provided herein and in the other Transaction Documents are cumulative and
are in addition to, and not exclusive of, any rights or remedies provided by law. The rights of the Collateral Agent and the Buyers
under any Transaction Document against any party thereto are not conditional or contingent on any attempt by the Collateral Agent
or any Buyer to exercise any of their respective rights under any other Transaction Document against such party or against any
other Person.


 


(d)
Any provision of this Guaranty that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the remaining portions hereof or affecting the validity
or enforceability of such provision in any other jurisdiction.


 


(e)
This Guaranty shall (i) be binding on each Guarantor and its respective successors and assigns, and (ii) inure, together with
all rights and remedies of the Collateral Agent and the Buyers hereunder, to the benefit of the Collateral Agent and the Buyers
and their respective successors, transferees and assigns. Without limiting the generality of clause (ii) of the immediately preceding
sentence, the Collateral Agent and any Buyer may assign or otherwise transfer its rights and obligations under the Securities
Purchase Agreement or any other Transaction Document to any other Person in accordance with the terms thereof, and such other
Person shall thereupon become vested with all of the benefits in respect thereof granted to the Collateral Agent or such Buyer,
as the case may be, herein or otherwise. None of the rights or obligations of any Guarantor hereunder may be assigned or otherwise
transferred without the prior written consent of each Buyer.


 


(f)
This Guaranty reflects the entire understanding of the transaction contemplated hereby and shall not be contradicted or qualified
by any other agreement, oral or written, entered into before the date hereof.


 


(g)
Section headings herein are included for convenience of reference only and shall not constitute a part of this Agreement for any
other purpose.


 


(h)
This Guaranty may be executed by each party hereto on a separate counterpart, each of which when so executed and delivered shall
be an original, but all of which together shall constitute one agreement. Delivery of an executed counterpart by facsimile or
other method of electronic transmission shall be equally effective as delivery of an original executed counterpart.


 


(i)
This Guaranty shall be governed by and construed in accordance with the law of the State
of New York applicable to contracts made and to be performed therein without regard to conflict of law principles.

ACCREDITED
INVESTOR QUESTIONNAIRE 


PLEASE
READ CAREFULLY 


 


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. o (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
                                         qualified as an “accredited investor”:
	 	 	 
	 	 	 



 


		☐	A
                                         trust which has total assets in excess of $5,000,000, not formed for the specific purpose
                                         of acquiring securities, whose purchase is directed by a “sophisticated person”
                                         within the meaning of Regulation D who has such knowledge and experience in financial
                                         and business matters as to be capable of evaluating the merits and risks of an investment

(Information)


 


From
May 18, 2015 until March 30, 2016, Erik Helenek, a Managing Director of the Placement Agent, served as a member of the Company’s
Board of Directors. Mr. Helenek was paid an annual fee of $40,000 and on May 18, 2015, the Company issued Mr. Helenek an option
to purchase 6,000 shares of Common Stock at an exercise price per share of $9.50, with 1/4 of the grant vesting on May 18, 2016
and 1/48 of the grant vesting ratably each month thereafter. No portion of the option granted was vested upon Mr. Helenek’s
resignation. For additional information regarding Mr. Helenek’s departure, see Current Report on Form 8-K filed April 5,
2016 (EDGAR Link), incorporated by reference herein. Subject to final approval of the Board of Directors, and in exchange
for his unpaid financial market advice and direction prior to his appointment as a director as well as his continued advice after
his resignation, the Company intends to issue Mr. Helenek a warrant to purchase 1,500 shares of common stock at an exercise price
of not less than $5.00, exercisable for three years from the date of Mr. Helenek’s resignation.

(Absence

Since
December 31, 2015, capital expenditures, individually or in the aggregate, in excess of $100,000:


 


		●	In
                                         2015, the Company had capitalized approximately $318,000 into fixed assets for payments
                                         made to Dresser-Rand in 2015 related to advance deposits and monthly lease payments for
                                         a leased turbine to be used in the Full Scale Acceptance Test (“FSAT”) unit.
                                         The Company had anticipated using that turbine after completion of testing and either
                                         selling or leasing the completed FSAT Powerstation. The turbine was returned to Dresser-Rand
                                         in August 2016 at which time it was determined that the leased turbine was not going
                                         to be incorporated into the finished Powerstation. We expect to recover some or all of
                                         the advance payments written off. However, due to uncertainty surrounding the amount
                                         and likelihood of the recovery of the advance payments, during the preparation of the
                                         Company’s Quarterly Report on Form 10-Q for the fiscal quarter ended September
                                         30, 2016, it was determined that the $318,000 capitalized in 2015 should be written off
                                         to expense. Any recovery will be accounted for prospectively as an expense reduction
                                         or an addition to fixed assets, or inventory, as appropriate, with a corresponding gain
                                         for the amount of the recovery. GAAP accounting precludes recording a contingent gain
                                         for this recovery based on information available as of November 10, 2016. The Company
                                         capitalized approximately $655,000 into fixed assets for additional expenditures and
                                         costs associated with the FSAT unit between January 1, 2015 and September 30, 2016.

See
Schedule 2.1(d) disclosure.


 


Pursuant
to the terms of that certain Securities Purchase Agreement (the “September Purchase Agreement”), dated as of
September 1, 2016, by and among the Company, Longboard Capital Advisors LLC, in its capacity as agent for the investors in their

On
September 1, 2016, we entered into a securities purchase agreement and related note agreements and warrant agreements whereby
we issued unsecured convertible promissory notes (the “Junior Notes”) and detachable five-year warrants to
purchase an aggregate of 124,999 shares of the Company’s common stock at an exercise price of $4.00 per share (the “September
2016 Financing”). The Company received total gross proceeds of $1,250,000, less transaction expenses of $20,000 consisting
of legal costs for net proceeds of $1,230,000. The Junior Notes bear interest at a rate of 12% per annum and mature on September
1, 2017, however such maturity date shall be concurrently extended with the consummation of the transactions contemplated by the
current securities purchase agreement and the related amendments agreements for the Senior Notes (as defined below). In connection
with the September 2016 Financing, on September 1, 2016, the Company and its wholly-owned subsidiary, Ener-Core Power, Inc. also
entered into a Subordination and Intercreditor Agreement with the investors, an investor who has agreed to serve as subordinated
agent, a senior lender with respect to a letter of credit for the benefit of the Company, and the collateral agent for certain
senior noteholders.


 


The
terms of the Junior Notes and the related warrants, including the related agreements, are described in the Company’s Current
Report on Form 8-K, filed September 2, 2016 (EDGAR Link), incorporated by reference herein.

On
September 23, 2016 AMTRA ENGINEERING B.V. filed a civil lawsuit (Case number 30-2016-00877078-CU-BC-CJC) in the Superior Court,
County of Orange, California against Ener-Core Power, Inc. alleging breach of contract and breach of warranty. To date, the Company
has not been legally served on this matter. The lawsuit is due to a billing dispute surrounding a contractor for the Attero 250Kw
unit delivered in June 2014 to the Netherlands. The Company has accrued $50,000 for this disputed amount as of December 31, 2015
based solely on billings received. In the event of service, the Company believes it has a substantial defense including proper
jurisdiction, will dispute all demands, and has a counter-claim against the contractor for $30,000.


 


Schedule
3(bb)


(Internal
Accounting and Disclosure Controls)


 


As
of December 31, 2015, as updated on September 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 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 full and complete written documentation of our internal control policies
                                         and procedures, primarily for controls related to our inventory procurement and management.
                                         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.



 






    	 	- 7 -	 



    


    

 


		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.



 


Between
January 1, 2016 and September 30, 2016 the Company’s management updated portions of control deficiency points #1 and #3
above to partially remediate the control deficiency and fully remediated control deficiencies 4, and 5. However, as of September
30, 2016, based on the control deficiencies remaining, 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 September 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.

(No
Disqualification Events)


 


Oppenheimer
& Co. Inc. is serving as placement agent in connection with the current offering (the “Placement Agent”);
pursuant to Rule 506(e), the Company discloses that:


 


		1.	On
                                         February 26, 2010, the Placement Agent entered into a Consent Order with the Massachusetts
                                         Securities Division (the “Division”). The Order concerned alleged
                                         violations of the Massachusetts Uniform Securities Act with respect to Oppenheimer’s
                                         sale of auction rate securities. The order found that the Placement Agent violated Section
                                         204(a)(2)(G) of Chapter 110A of Massachusetts General Laws. The Placement Agent was required
                                         to buy back illiquid auction rate securities from investors and pay hearing costs in
                                         an amount totaling $250,000.



 


		2.	On
                                         July 9, 2007, the Placement Agent entered into a Consent Order with the Division. The
                                         Order alleged that the Placement Agent failed to supervise a registered representative
                                         who engaged in unlawful activities. The Division alleged that the Placement Agent made
                                         false and misleading filings to the Division during the course of its investigation of
                                         the matters addressed in the Order and accordingly violated Massachusetts General Laws,
                                         Chapter 110A, Section 404. The Placement Agent was required to pay a fine of $1,000,000,
                                         make restitution to the investor, cease and desist from further violations and retain
                                         an independent consultant.



 


		3.	On
                                         January 27, 2015, the Placement Agent entered into an order with the SEC pursuant to
                                         which the Placement Agent was censured and agreed to (i) pay $10 million, comprised of
                                         $4,168,400 in disgorgement, $753,471 in prejudgment interest and $5,078,129 in civil
                                         penalties; (ii) cease and desist from committing or causing any violations of Sections
                                         15(a) and 17(a) of the 1934 Act and Rules 17a-3 and 17a-8 adopted thereunder and of Section
                                         5 of the 1933 Act; and (iii) retain an independent consultant over a five-year period
                                         to conduct a review of the Placement Agent’s policies and procedures as they relate
                                         to compliance with Section 5 of the 1933 Act, the Bank Secrecy Act, the Patriot Act,
                                         the Placement Agent’s AML program and the proper recognition of liabilities and
                                         expenses associated with foreign entities trading on behalf of customers and U.S. customers
                                         trading through foreign financial institutions. This settlement was based on the Placement
                                         Agent’s conduct relating to two separate customer accounts. The first account involved
                                         aiding and abetting a customer’s violation of the broker-dealer registration requirements
                                         under the 1934 Act, failure to file Suspicious Activity Reports to report potential misconduct
                                         by this customer and failure to properly report, withhold and recognize backup withholding
                                         taxes. The second account involved failure to respond to red flags and conduct an inquiry
                                         into whether a customer’s unregistered sales of penny stocks were exempt from 1933
                                         Act registration requirements and failure to reasonably supervise with a view toward
                                         detecting and preventing violations of the registration provisions. The Placement Agent
                                         also agreed to pay an additional $10 million in civil penalties to settle a parallel
                                         action by the Treasury Department’s Financial Crimes Enforcement Network. The Placement
                                         Agent received an SEC order granting waiver of disqualification under Rule 506(d)(1)(ii)
                                         on January 27, 2015.
