SECURITIES
PURCHASE AGREEMENT

 

SECURITIES
PURCHASE AGREEMENT (the "Agreement"), dated as of May 7, 2015, by and among Ener-Core, Inc., a Nevada corporation,
with headquarters located at 9400 Toledo Way, Irvine, California 92618 (the "Company"), and the investors listed
on the Schedule of Buyers attached hereto (individually, a "Buyer" and collectively, the "Buyers").

 

WHEREAS:

 

A.The
Company and each Buyer is 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 Regulation
D ("Regulation D") as promulgated by the United States Securities and Exchange Commission (the "SEC")
under the 1933 Act.

 

B.The
Company had previously entered into that certain Securities Purchase Agreement (the “April 2015 SPA”) dated
April 22, 2015 with seven accredited investors (the “April 2015 Investors”) pursuant to which the Company issued
senior secured promissory notes with an aggregate principal amount of $3,100,000 (the “April 2015 Notes”) and
warrants for the purchase of up to an aggregate 6,813,186 (“April 2015 Warrants”) in exchange for the April
2015 Investors’ payment of an aggregate $3,100,000 (the financing transaction contemplated under the April 2015 SPA is hereinafter
referred as the “April 2015 Financing”).

 

C.Pursuant
to the terms of the April 2015 SPA, as amended by that certain First Amendment to the Securities Purchase Agreement dated May
7, 2015 by and among the Company, the Collateral Agent and four April 2015 Investors (the “April 2015 Required Holders”)
holding, in the aggregate, a majority of the April 2015 Conversion Shares and April 2015 Warrant Shares (as both terms are defined
below)(the “April 2015 SPA Amendment”, and together with the April 2015 SPA, hereinafter collectively referred
to as the “Amended April 2015 SPA”), the April 2015 Investors agreed to allow the Company to issue an additional
$1,900,000 principal amount senior secured promissory notes with the same percentage of warrants as was issuable under the terms
of the April 2015 Warrants (the “Additional Subscription”) on substantially the same terms as the April 2015
Notes and April 2015 Warrants, but in any event with no terms more favorable to the investors in the Additional Subscription than
those of the April 2015 Investors in the April 2015 Financing.

 

D.The
Company now desires to enter into the Additional Subscription with the Buyers and thus the Company has authorized the issuance
of additional senior secured notes and warrants of the Company, in substantially the forms attached hereto as Exhibit A
(the "Notes") and Exhibit B (the “Warrants”), which Notes and Warrants have substantially
the same terms as those set forth in the April 2015 Notes and April 2015 Warrants.

 

E.The
Notes shall be convertible into the Company's common stock, par value $0.0001 per share (the "Common Stock")
(the shares of Common Stock issuable pursuant to the terms of the Notes, including, without limitation, upon conversion, upon
payment of interest, or otherwise, collectively, the "Conversion Shares"), in accordance with the terms of the
Notes.

 

    	- 1 -

    	 

    

 

F.Each
Buyer wishes to purchase, and the Company wishes to sell, upon the terms and conditions stated in this Agreement, (i) that aggregate
principal amount of Notes set forth opposite such Buyer's name in column (3) on the Schedule of Buyers attached hereto (which
aggregate principal amount of Notes for all Buyers shall be up to $1,900,000), and (ii) Warrants, in substantially the form attached
hereto as Exhibit B (the " Warrants"), representing the right to acquire that number of shares of Common
Stock set forth opposite such Buyer's name in column (4) on the Schedule of Buyers (as exercised, collectively, the "Warrant
Shares").

 

G.The
Notes will rank pari passu with the April 2015 Notes and will rank senior to all other outstanding and future indebtedness
of the Company, and its Subsidiaries (as defined below), will be guaranteed by all direct and indirect Subsidiaries (as defined
in Section 3(a)) of the Company, currently formed or formed in the future, as evidenced by that certain Guaranty Agreement dated
April 23, 2015 executed by Ener-Core Power, Inc., as amended by that certain First Amendment to the Guaranty dated May 7, 2015
(the “Guaranty Amendment”) by and among Ener-Core Power, Inc. and the April 2015 Investors (as may be further
amended or modified from time to time in accordance with its terms, collectively, the "Guaranty Agreement"),
substantially in the forms attached hereto as Exhibit C, and will be secured by a first priority perfected security interest
(subject to Permitted Liens under and as defined in the Notes) in all of the current and future assets of the Company and all
direct and indirect Subsidiaries of the Company, except for the “Excluded Assets” (as such term is defined in the
Security Agreement), currently formed or formed in the future, as evidenced by that certain Pledge and Security Agreement dated
April 23, 2015 by and among the Company and the Collateral Agent, as amended by that certain First Amendment to the Pledge and
Security Agreement dated May 7, 2015 (the “Security Agreement Amendment”) by and among the Company and the
Collateral Agent (as may be further amended or modified from time to time in accordance with its terms, collectively, the "Security
Agreement" and together with the Guaranty Agreement and any ancillary documents related thereto, collectively, the "Security
Documents"), substantially in the forms attached hereto as Exhibit D.

 

H.The
Notes, the Conversion Shares, the Warrants and the Warrant Shares collectively are referred to herein as the "Securities".
The shares of Common Stock issuable pursuant to the terms of the April 2015 Notes, including, without limitation, upon conversion,
upon payment of interest, or otherwise, are hereinafter referred to as the “April 2015 Conversion Shares”.
The “April 2015 Assumed Conversion Price” means the “Assumed Conversion Price” as such term is
defined in the April 2015 Notes. The shares of Common Stock issuable pursuant to the terms of the April 2015 Warrants are hereinafter
referred to as the “April 2015 Warrant Shares”. The April 2015 Notes, the April 2015 Conversion Shares, the

(c)Reliance
on Exemptions. Such Buyer understands that the Securities are being offered and sold to it in reliance on specific exemptions

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

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,

3.REPRESENTATIONS
AND WARRANTIES OF THE COMPANY.

 

The
Company represents and warrants to each of the Buyers 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, individually or 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

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. 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' respective boards of directors (or other applicable governing body) and (other than filings as may be required by
state securities agencies) no further filing, consent, or authorization is required by such Subsidiaries, their respective boards
of directors (or other applicable governing body) or shareholders (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,

rights and remedies.

 

(c)Issuance
of Securities. The issuance of the Notes and the Warrants are duly authorized and, upon issuance, shall be validly issued

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. 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 Closing Date, and the Company and its Subsidiaries are unaware of any facts or circumstances that might prevent the Company

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.

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

thereto, or (ii) in the case of unaudited interim statements, to the extent they may exclude footnotes or may be condensed or
summary statements) and fairly present in all material respects the financial position 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). No other information provided by or on behalf of the Company to the Buyers which is not included
in the SEC Documents, including, without limitation, information referred to in Section 2(d) of this Agreement or in the disclosure
schedules to this Agreement, contains any untrue statement of a material fact or omits to state any material fact necessary in

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(m), during the two (2) years prior to the date hereof,

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

(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.

 

(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

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 reasonably be expected
to have a Material Adverse Effect.

 

(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)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 of the Company or
any of its Subsidiaries (as defined in Rule 501(f) of the 1933 Act) 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.

 

(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. Each of patents owned by the Company or any of its Subsidiaries is listed on Schedule 3(w)(i). Except
as set forth in Schedule 3(w)(ii), 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 which 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.

respective businesses and (iii) are in compliance with all terms and conditions of any such permit, license or approval where,
in each of the foregoing clauses (i), (ii) and (iii), the failure to so comply could be reasonably expected to have, individually
or in the aggregate, a Material Adverse Effect. 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

in any material amount claimed to be due by the taxing authority of any jurisdiction, and the officers of the Company know of
no basis for any such claim.

 

(bb)Internal
Accounting and Disclosure Controls. Except as set forth in Schedule 3(bb), the Company and each of its Subsidiaries
maintain a system of internal accounting controls sufficient to provide reasonable assurance that (i) transactions are executed
in accordance with management's general or specific authorizations, (ii) transactions are recorded as necessary to permit preparation
of financial statements in conformity with generally accepted accounting principles and to maintain asset and liability accountability,
(iii) access to assets or incurrence of liabilities is permitted only in accordance with management's general or specific authorization
and (iv) the recorded accountability for assets and liabilities is compared with the existing assets and liabilities at reasonable
intervals and appropriate action is taken with respect to any difference. The Company maintains disclosure 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. During the twelve months
prior to the date hereof neither the Company nor any of its Subsidiaries has received any notice or correspondence from any accountant
relating to any material weakness in any part of the system of internal accounting controls of the Company or any of its Subsidiaries.

or that otherwise would be reasonably likely to have a Material Adverse Effect.

 

(dd)Ranking
of Notes. Except for the April 2015 Notes or as set forth in Schedule 3(dd), no Indebtedness of the Company or any

as may be necessary or, in the opinion of the Collateral Agent, desirable to perfect the security interests purported to be created
by the Security Agreement, together with copies of such financing statements, none of which, except as otherwise agreed in writing
by the Collateral Agent, shall cover any of the Collateral, and the results of searches for any tax lien and judgment lien filed
against such person or its property, which results, except as otherwise agreed to in writing by the Collateral Agent, shall not
show any such liens.

 

(xiii)The
Collateral Agent shall have received the Security Agreement, duly executed by the Company and each of its Subsidiaries, together
with the original stock certificates representing all of the equity interests and all promissory notes required to be pledged
thereunder, accompanied by undated stock powers and allonges executed in blank and other proper instruments of transfer.

(xiv)The
Company shall have delivered to such Buyer such other documents relating to the transactions contemplated by this Agreement as
such Buyer or its counsel may reasonably request.

 

8.TERMINATION.
In the event that the Closing shall not have occurred with respect to a Buyer on or before five (5) Business Days from the date
hereof due to the Company's or such Buyer's failure to satisfy the conditions set forth in Sections 6 and 7 above (and the nonbreaching
party's failure to waive such unsatisfied condition(s)), the nonbreaching party shall have the option to terminate this Agreement
with respect to such breaching party at the close of business on such date by delivering a written notice to that effect to each
other party to this Agreement and without liability of any party to any other party.

 

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.

 

    	- 30 -

    	 

    

 

(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 sum
of (1) 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), and
(2) the aggregate number of the April 2015 Conversion Shares and the April 2015 Warrant Shares issued or issuable under the April
2015 Notes (calculated using the April 2015 Assumed Conversion Price) and April 2015 Warrants (without regard to any limitation
on conversion or exercise set forth therein), and shall include Empery Asset Master, Ltd. (the April 2015 Financing lead investor
and hereinafter referred to as “Empery”) so long as Empery or any of its affiliates holds any April 2015 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(r) 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
and assigns, including any purchasers of the Notes or the Warrants. The Company shall not assign this Agreement or any rights
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
assignee shall be deemed to be a Buyer hereunder with respect to such assigned rights.

 

(h)No
Third Party Beneficiaries. This Agreement is intended for the benefit of the parties hereto and their respective permitted

(i)Survival.
Unless this Agreement is terminated under Section 8, the representations and warranties of the Company and the Buyers contained

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.

 

    	- 33 -

    	 

    

 

(k)Indemnification.
(i)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 shareholders, 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.

 

    	- 34 -

    	 

    

 

(ii)Promptly
after receipt by an Indemnitee under this Section 9(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 9(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 9(k), except to the extent that the indemnifying party is prejudiced in its ability to defend such action.

 

(iii)The
indemnification required by this Section 9(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.

 

    	- 35 -

    	 

    

 

(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.

GUARANTY

 

GUARANTY,
dated as of April 22, 2015, 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 Nevada corporation (the "Company"), and each party listed as a "Buyer" on the
Schedule of Buyers attached to the Securities Purchase Agreement (each a "Buyer", and collectively, the "Buyers")
are parties to that certain Securities Purchase Agreement, dated as of April 21, 2015 (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 the date hereof (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:

 

SECTION
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.

 

    	 

    	 

    

 

SECTION
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").

 

SECTION
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.

 

    	 

    	 

    

 

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).

 

SECTION
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.

 

    	 

    	 

    

 

SECTION
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.

 

SECTION
6.    Representations, Warranties and Covenants.

 

(a)
          Each Guarantor hereby represents and warrants as of the date first written

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

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.

 

(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

(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

of the Company or the other Transaction Parties that may come under the control of the Collateral Agent or any Buyer.

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.

 

    	 

    	 

    

 

SECTION
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.

SECTION
9.    CONSENT TO JURISDICTION; SERVICE OF PROCESS
AND VENUE. ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS GUARANTY OR ANY OTHER TRANSACTION 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 FOR THE SOUTHERN DISTRICT
OF NEW YORK, AND, BY EXECUTION AND DELIVERY OF THIS AGREEMENT, EACH GUARANTOR HEREBY IRREVOCABLY ACCEPTS IN RESPECT OF ITS PROPERTY,

THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE JURISDICTION OR LAYING OF VENUE OF
ANY SUCH LITIGATION BROUGHT IN ANY SUCH COURT REFERRED TO ABOVE AND ANY CLAIM THAT ANY SUCH LITIGATION HAS BEEN BROUGHT IN AN

OTHERWISE) WITH RESPECT TO ITSELF OR ITS PROPERTY, EACH GUARANTOR HEREBY IRREVOCABLY WAIVES SUCH IMMUNITY IN RESPECT OF ITS OBLIGATIONS
UNDER THIS GUARANTY AND THE OTHER TRANSACTION DOCUMENTS.

 

    	 

    	 

    

 

SECTION
10.    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 ANY SUCH ACTION, PROCEEDING OR COUNTERCLAIM
SHALL BE TRIED BEFORE A COURT AND NOT BEFORE A JURY. EACH GUARANTOR CERTIFIES THAT NO OFFICER, REPRESENTATIVE, AGENT OR ATTORNEY
OF ANY BUYER HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT ANY BUYER WOULD NOT, IN THE EVENT OF ANY ACTION, PROCEEDING OR COUNTERCLAIM,
SEEK TO ENFORCE THE FOREGOING WAIVERS. EACH GUARANTOR HEREBY ACKNOWLEDGES THAT THIS PROVISION IS A MATERIAL INDUCEMENT FOR THE
BUYERS ENTERING INTO THE OTHER TRANSACTION DOCUMENTS.

 

SECTION
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,

 

    	 

    	 

    

 

(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.

 

SECTION
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)           No
amendment or waiver of any provision of this Guaranty and no consent to any departure by any Guarantor therefrom shall in any
event be effective unless the same shall be in writing and signed by each Guarantor and each Buyer, and then such waiver or consent
shall be effective only in the specific instance and for the specific purpose for which given.

 

    	 

    	 

    

 

(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.

This

Agreement”). Capitalized terms used herein and not otherwise defined shall have the meaning assigned to them in the
Purchase Agreement.

                                         Back-up Officer’s Certificate executed by the Company as of May __, 2015, covering
                                         various factual matters as to which the opinions herein relate (the “Opinion
                                         Certificate”).

 

Items
(a) through (i) are sometimes hereinafter referred to collectively as the “Agreements”.

 

We
have also examined such other matters of law, and originals or copies of such other documents, corporate records and other materials,
that we consider relevant for purposes of this opinion. In giving this opinion, we have assumed, with your permission, the genuineness
of all signatures, the legal capacity of natural persons and the authenticity and completeness of all documents we have examined.
As to questions of fact relevant to this opinion, with your permission and without any independent investigation or verification,
we have relied upon, and assumed the accuracy of, the representations and warranties of each party in the Agreements and have
relied upon certificates of officers of the Company and written statements of certain public officials which we consider necessary
or advisable for the purpose of rendering this opinion.

For
purposes of this opinion, we are assuming that the Buyers have all requisite power and authority, and have taken any and all necessary
corporate, partnership or limited liability company action, to execute and deliver the Agreements, and we are assuming that the
representations and warranties made by the Buyers in the Agreements and pursuant thereto are true and correct. We are also assuming
that the Buyers have purchased the Notes and Warrants for value, in good faith and without notice of any adverse claims within
the meaning of the UCC in effect in the State of Delaware (“Delaware UCC”) and that there are no other extrinsic
agreements or understandings among the parties to the Agreements that would modify or otherwise interpret the terms thereof. We
also have assumed, with your permission and without any independent verification, compliance by each party to the Agreements with
its agreements in the respective Agreements, and that each of the Agreements constitutes the legal, valid and binding obligation
of each party to it (other than the Company and the Subsidiary) and is enforceable against each such party in accordance with
its terms.

 

We
note that some of the Agreements provide that they are to be governed by the law of the State of New York. Except with respect
to those portions of the Agreements that are governed by the Delaware General Corporation Law, our opinions regarding the validity,
binding effect, and enforceability of the Agreements are given as though each of the Agreements were governed by the internal
laws of the State of California. We call your attention to the fact that the Company is incorporated in the State of Nevada and
the Subsidiary is incorporated in the State of Delaware and that the Company and the Subsidiary may hold assets in foreign countries
and own securities of companies organized under the laws of foreign jurisdictions. For purposes of this opinion, we have assumed
with your permission that the laws of the State of Nevada are identical to those of the State of California. We render no opinion
with regard to the applicability of any foreign laws. We express no opinion except to the extent that Article 9 of the Delaware
UCC governs the creation or perfection of the security interests referred to in this opinion.

 

As
used in this opinion, the expression “to our knowledge”, “known to us” or similar language with reference
to matters of fact means that, after an examination of documents made available to us by the Company, and after inquiries of officers
of the Company, but without any further independent factual investigation, we find no reason to believe that the opinions expressed
herein are factually incorrect. When reference is made in this opinion to our “knowledge” of certain matters or to
matters “known to us”, it means the actual present knowledge and conscious awareness of those matters by the attorneys
at our firm involved in acting as counsel to the Company. Except to the extent expressly set forth herein, we have not undertaken
any independent investigation to determine the existence or absence of any fact, and no inference as to our knowledge of the existence
or absence of any fact should be drawn from our representation of the Company or the rendering of the opinion set forth below.

 

    	 

    	 

    

May __, 2015

Our
opinion set forth in paragraph 1 below with respect to the Company is given as of the date of, and is based solely upon, a Certificate
of Good Standing from the Secretary of State of Nevada dated April 30, 2015, and the State of California dated April 29, 2015.

 

Our
opinion set forth in paragraph 1 below with respect to the Subsidiary is given as of the date of, and is based solely upon, a
Certificate of Good Standing from the Secretary of State of Delaware dated April 29, 2015, and the State of California dated April
29, 2015.

 

For
purposes of the opinions contained in paragraph 10 below, we have assumed that each of the Company and the Subsidiary has rights
in its personal property collateral.

 

No
opinion is being rendered (i) whether the properties described in any security agreement are the properties and interests intended
to be covered thereby; (ii) the priority of any security interest; or (ii) with respect to a security interest in collateral consisting
of a debtor's rights under any rule of law, statute or regulation, or contract, permit, license, franchise or other agreement
containing any term, that prohibits, restricts, or requires the consent of any individual or entity (“Person”)
to, the assignment or transfer of, or creation, attachment, or perfection of, a security interest in any such rights, and such
prohibition or restriction has not been waived by, or such consent obtained from, such Person, or such prohibition or restriction
is not ineffective pursuant to Sections 9-406 through 9-409 of the Delaware UCC.

 

In
addition we call your attention to the following insofar as Article 9 of the Delaware UCC is applicable:

 

		(i)	the
                                         effectiveness of financing statements generally lapses five years from the date of filing
                                         unless a continuation statement is filed within six months prior to such termination
                                         in accordance with Section 9-515;
	 	 	 
		(ii)	Section
                                         9-507(c) provides that if the name that a filed financing statement provides for a debtor
                                         becomes insufficient as the name of the debtor under Section 9-503(a) so that a filed
                                         financing statement becomes seriously misleading under Section 9-506, the filing is not
                                         effective to perfect a security interest in collateral acquired by the debtor more than
                                         four months after such change unless an amendment to the financing statement which renders
                                         the financing statement not seriously misleading is filed before the expiration of that
                                         period;
	 	 	 
		(iii)	if
                                         the difference between the name of an original debtor and a new debtor that acquires
                                         an interest in the collateral of the original debtor causes a filed financing statement
                                         naming the original debtor to become seriously misleading under Section 9-506, Section
                                         9-508(b) provides that (i) the filing is effective to perfect a security interest in
                                         collateral acquired by the new debtor before and within the four months after the new
                                         debtor acquires such an interest, and (ii) the filing is not effective to perfect a security
                                         interest in collateral acquired more than four months after the new debtor acquires such
                                         an interest unless an initial financing statement providing the name of the new debtor
                                         is filed before the expiration of that time;

                                         collateral is transferred to a person that thereby becomes a debtor and such person is
                                         located in another jurisdiction, Section 9-316 requires that a new financing statement
                                         be filed in such new jurisdiction within one year after such transfer of collateral to
                                         continue perfection of the security interest;

 

		(v)	if
                                         collateral is acquired by the debtor subject to a security interest created by another
                                         person that was perfected at the time of such transfer, under Section 9-325 the security
                                         interest in such collateral granted by the debtor may be subordinate to the security
                                         interest in such collateral granted by such other person;

 

		(vi)	if
                                         the location of a debtor changes to a jurisdiction in which a financing statement has
                                         not been filed, Section 9-316 requires that a new financing statement be filed in such
                                         new jurisdiction within four months after such change to continue perfection of the security
                                         interest;

 

		(vii)	under
                                         certain circumstances described in Section 9-315, perfection of, and the rights of a
                                         secured party to enforce a security interest in, proceeds of collateral may be limited;

 

		(viii)	under
                                         certain circumstances, including those described in Sections 9-320, 9-323, 9-330, and
                                         9-331, buyers of collateral may take such collateral free of a perfected security interest;

 

		(ix)	Section
                                         552 of the United States Bankruptcy Code (11 U.S.C. §552) limits the extent to which
                                         property acquired by a debtor after the commencement of a case under the Bankruptcy Code
                                         may be subject to a lien resulting from any security agreement entered into by the debtor
                                         before the commencement of the case; and

 

		(x)	Section
                                         9-301 provides that while a debtor is located in a jurisdiction, the local law of that
                                         jurisdiction governs perfection, the effect of perfection or nonperfection, and the priority
                                         of a security interest in collateral. Section 9-307(e) states that a registered organization
                                         that is organized under the law of a state is located in that state. Section 9-102(71)
                                         provides that, a “registered organization” means an organization organized
                                         solely under the law of a single state or the United States and as to which the state
                                         or the United States must maintain a public record showing the organization to have been
                                         organized.

 

Based
upon and subject to the foregoing and the comments and qualifications set forth below, except as set forth in the schedules of
exceptions to the Agreements, if any, we are of the opinion that:

 

1.Each
of the Company and the Subsidiary is an entity duly formed and validly existing under the laws of the state of its formation and
is in good standing under such laws. Each of the Company and the Subsidiary has the requisite power to own, lease and operate
its properties and to conduct its business as presently conducted. Each of the Company and the Subsidiary is duly qualified to
do business and is in good standing in each jurisdiction in which the Company and the Subsidiary, respectively, conducts business.

of termination, cancellation or acceleration under, (i) the Articles or the Company’s Bylaws or the organizational documents
of the Subsidiary, (ii) any other agreement, note, lease, mortgage, deed or other instrument to which the Company or the Subsidiary

containing anti-dilution or similar provisions that will be triggered by the issuance of the Notes, the Warrants, the Conversion

6.Subject
to the accuracy of the representations and warranties made by the Buyers in the Purchase Agreement, the offer and sale of the
Notes and the Warrants in accordance with the Purchase Agreement and the issuance and delivery of the Conversion Shares and the
Warrant Shares in accordance with the Agreements constitute transactions exempt from the registration requirements of the Securities
Act of 1933, as amended (the “1933 Act”).

 

7.No

10.The
Amended Security Agreement creates a valid security interest in favor of the Collateral Agent for the benefit of the Buyers and
the April 2015 Buyers (applied ratably to the Buyers and the April 2015 Buyers based on the aggregate principal amount of outstanding
Notes and April 2015 Notes, taken as a whole) in the Collateral purported to be covered thereby as security for the obligations
purported to be secured thereby. Each Financing Statement filed in the states set forth on Schedule A hereto (each, a “State”)
as delivered to us by Buyers’ counsel was in appropriate form for filing, and upon filing in the offices of the Secretary
of State of the applicable State, resulted in the perfection of the security interests in the Collateral covered by such Financing
Statement to the extent that such Collateral consists of the type of property in which a security interest may be created under
Article 9 of the Delaware UCC as currently in effect and in which a security interest may be perfected by the filing of a financing
statement in Delaware.

 

11.The
Company is the owner of the Pledged Shares (as defined in the Security Agreement) in existence on the date hereof, free and clear
of any Lien (as defined in the Security Agreement) except for the Lien created by the Security Agreement and except for Permitted
Liens (as defined in the Security Agreement). The Pledged Shares have been duly authorized and validly issued, are fully paid
and nonassessable and constitute 100% of the issued and outstanding shares of share capital of the Subsidiary. The Collateral
Agent shall have a perfected security interest in the Pledged Shares represented by certificates described in Schedule VIII of
the Security Agreement upon delivery of such certificates to the Collateral Agent in, and while located in, the State of New York,
together with undated stock powers duly endorsed in blank with respected thereto by an effective endorsement.

 

The
foregoing opinions are subject to the following comments and qualifications:

 

a.The
enforceability of each of the Agreements to which it is a party against the Company or the Subsidiary may be limited by bankruptcy,
insolvency, fraudulent conveyance, fraudulent transfer, reorganization, moratorium and other similar laws relating to or affecting
creditors’ rights generally and by general equitable principles (regardless of whether enforcement is sought in equity or
at law), including, without limitation, principles regarding good faith and fair dealing.

                                         or violation of securities or other laws, to the extent the provisions thereof are or
                                         may be subject to limitations of public policy and the effect of applicable statutes

Ener-Core,
Inc.

Re:    Ener-Core,
Inc. - Lock-Up Agreement

 

Dear
Sirs:

 

This
Lock-Up Agreement is being delivered to you in connection with the Securities Purchase Agreement (the "Purchase Agreement"),
dated as of April 22, 2015 (the "Subscription Date") by and among Ener-Core, Inc. (the "Company")
and the investors party thereto (the "Buyers"), with respect to the issuance of (i) senior secured notes of the
Company (the "Notes") pursuant to which shares of the Company's common stock, par value $0.0001 per share (the
"Common Stock") may be issued and (ii) warrants (the "Warrants") which Warrants will be exercisable
to purchase Common Stock. Capitalized terms used herein and not otherwise defined
herein shall have the respective meanings set forth in the Purchase Agreement.

 

In
order to induce the Buyers to enter into the Purchase Agreement, the undersigned agrees that, commencing on the date of pricing
of the first underwritten public offering by the Company occurring after the date here and ending on the date that is ninety days
after the consummation of such underwritten public offering (the "Lock-Up
Period"), the undersigned will not, and will cause all affiliates (as defined in Rule 144 promulgated under the
Securities Act of 1933, as amended) ("affiliates") of the undersigned or any person in privity with the undersigned
or any affiliate of the undersigned not to, (i) sell, offer to sell, contract or agree
to sell, hypothecate, pledge, grant any option to purchase, make any short sale or
otherwise dispose of or agree to dispose of, directly or indirectly, any shares of
Common Stock or Common Stock Equivalents, or
establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section
16 of the Securities and Exchange Act of 1934, as amended and the rules and regulations of the Securities and Exchange Commission
promulgated thereunder with respect to any shares of Common Stock or Common
Stock Equivalents owned directly by the undersigned (including holding as a custodian) or
with respect to which the undersigned has beneficial ownership within the rules and regulations of the Securities and Exchange
Commission (collectively, the "Undersigned's Shares"), or (ii) enter into any swap or other arrangement
that transfers to another, in whole or in part, any of the economic consequences of ownership of any
of the Undersigned's Shares, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery
of shares of Common Stock or other securities, in cash or otherwise, (iii) make any demand for or exercise any right or cause
to be filed a registration statement, including any amendments thereto, with respect to the registration of any shares of Common
Stock or Common Stock Equivalents or (iv)
publicly disclose the intention to do any of the foregoing. As used herein, (x) "Convertible Securities" means
any stock or securities (other than Options) convertible into or exercisable or exchangeable for shares of Common Stock, (y) "Options"
means any rights, warrants or options to subscribe for or purchase Common Stock or Convertible Securities and (z) "Common
Stock Equivalents" means, collectively, Options and Convertible Securities.

 

    	 

    	 

    

 

The
foregoing restriction is expressly agreed to preclude the undersigned, and any affiliate of the undersigned and
any person in privity with the undersigned or any affiliate of the undersigned, from engaging
in any hedging or other transaction which is designed to or which reasonably could be expected to lead to or result in a sale
or disposition of the Undersigned's Shares even if the Undersigned's Shares would be disposed of by someone other than the undersigned.
Such prohibited hedging or other transactions would include, without limitation, any short sale or any purchase, sale or grant
of any right (including, without limitation, any put or call option) with respect to any of the Undersigned's Shares or with respect
to any security that includes, relates to, or derives any significant part of its value from the Undersigned's Shares.

 

Notwithstanding
the foregoing, the undersigned may transfer the Undersigned's Shares (i) as a bona fide gift or gifts, provided that the
donee or donees thereof agree to be bound in writing by the restrictions set forth herein or (ii) to any trust for the direct
or indirect benefit of the undersigned or the immediate family of the undersigned, provided that the trustee of the trust agrees
to be bound in writing by the restrictions set forth herein, and provided further that any such transfer shall not involve a disposition
for value. For purposes of this Lock-Up Agreement, "immediate family" shall mean any relationship by blood, marriage
or adoption, not more remote than first cousin. The undersigned now has, and, except as contemplated by the immediately preceding
sentence, for the duration of this Lock-Up Agreement will have, good and marketable title to the Undersigned's Shares, free and
clear of all liens, encumbrances, and claims whatsoever. The undersigned also agrees and consents to the entry of stop transfer
instructions with the Company's transfer agent (the "Transfer Agent") and registrar against the transfer of the
Undersigned's Shares except in compliance with the foregoing restrictions.

 

The
undersigned hereby represents and warrants to the Company that it is an "affiliate"
(as such term is defined in Rule 144 promulgated under the Securities Act of 1933, as amended) of
the Company and acknowledges and agrees that it is subject to the restrictions on sales applicable to affiliates of an issuer
under Rule 144, including without limitation, the limitations on the amount of securities to be sold under Rule 144(e). The undersigned
also acknowledges and agrees that any purchaser or transferee of any securities from the undersigned, while the undersigned is
an affiliate of the Company (other than sales by the undersigned in compliance with Rule 144), will receive "restricted securities"
(as such term is defined under Rule 144(a)). The undersigned further covenants and agrees that regardless of whether or not the
undersigned remains an "affiliate" of the Company, at all times during the six month period beginning on the date hereof,
that it will treat all sales of securities under Rule 144 as if the undersigned was and is an "affiliate" of the Company,
including limiting the amount of securities to be sold to that permitted under Rule 144(e), regardless of whether or not Rule
144(e) is applicable to the undersigned at the time of any such sale.

 

In
order to enforce this covenant, the Company shall impose irrevocable stop-transfer instructions preventing the Transfer Agent
from effecting any actions in violation of this Lock-Up Agreement.

 

    	 

    	 

    

 

The
undersigned acknowledges that the execution, delivery and performance of this Lock-Up Agreement is a material inducement to each
Buyer to complete the transactions contemplated by the Purchase Agreement and that the Company shall be entitled to specific performance
of the undersigned's obligations hereunder. The undersigned hereby represents that the undersigned has the power and authority
to execute, deliver and perform this Lock-Up Agreement, that the undersigned has received adequate consideration therefor and
that the undersigned will indirectly benefit from the closing of the transactions contemplated by the Purchase Agreement.

 

The
undersigned understands and agrees that this Lock-Up Agreement is irrevocable and shall be binding upon the undersigned's heirs,
legal representatives, successors, and assigns.

 

This
Lock-Up Agreement may be executed in two counterparts, each of which shall be deemed an original but both of which shall be considered
one and the same instrument.

 

This
Lock-Up Agreement will be governed by and construed in accordance with the laws of the State of New York, without giving effect
to any choice of law or conflicting provision or rule (whether of the State of New York, or any other jurisdiction) that would
cause the laws of any jurisdiction other than the State of New York to be applied. In furtherance of the foregoing, the internal
laws of the State of New York will control the interpretation and construction of this Lock-Up Agreement, even if under such jurisdiction's
choice of law or conflict of law analysis, the substantive law of some other jurisdiction would ordinarily apply.

On
August 14, 2013, the Company failed to file its Form 10-Q filing for the quarter ended June 30, 2013 on time and failed to file
an extension for its Form 10-Q filing on August 15, 2013. The Company resolved the filing delinquency by filing a Form 12b-25
on August 16, 2013 and completed its Form 10-Q filing on August 19, 2013.

 

Schedule

(Material
Adverse Change/Development since December 31, 2014)

 

None, except

On
March 24, 2015 the Company reduced the exercise price of warrants (the “April 2014 Warrants”) for the purchase
of up to 4,097,015 issued in April 2014 from $0.50 per share to $0.11 per share. On April 2, 2015, the Company entered in an Exchange
Agreement (the “Exchange Agreement”) with each holder of the April 2014 Warrants (the “April 2014
Investors”) whereby the Company agreed to issue an aggregate 3,687,316 shares of the Company’s common stock in
exchange for the cancellation of all of the April 2014 Warrants (the “Warrant Exchange”). The completion of
the delivery of the Exchange Shares and the closing of the Warrant Exchange occurred on April 17, 2015. See also our Current Report
on Form 8-K filed with the Securities and Exchange Commission (“SEC”) on April 7, 2015 and Exhibit 10.1 thereto
and our Current Report on Form 8-K filed with the SEC on April 17, 2015. The Exchange Shares to be issued are subject to certain
lockup provisions until the earlier of 60 days after April 17, 2015, or the date that the weighted average price of the Company’s
common stock equals or exceeds $0.30 per share for ten consecutive trading days. See also Exhibit 10.2 to the Form 8-K filed April

On

to 21,000,000 shares from 14,000,000 shares.

 

    	 

    	 

    

 

As
disclosed in the Company’s current report on Form 8-K filed with the Securities and Exchange Commission on April 23, 2015
(the “April Form 8-K”), on April 22, 2015, the Company entered into a Securities Purchase Agreement (“Purchase
Agreement”) with seven accredited investors (the “April Investors”). At the closing of the transactions contemplated
under the Purchase Agreement (the “April 2015 Financing”), which occurred on April 23, 2015 (the “April Closing”),
the Company sold and issued to the April Investors, the Company’s senior secured promissory notes with an aggregate principal
amount of $3,100,000 (the “Notes”) and warrants to purchase up to 6,813,186 shares of the Company’s common stock
(the “Warrants”).  The material terms and conditions of the Purchase Agreement, Notes and Warrants are further
described in the April Form 8-K and the exhibits thereto.

 

On
May 1, 2015, the Company entered into a Securities Purchase Agreement and Registration Rights Agreement with thirty accredited

the Company sold to the May 2015 Investors an aggregate of 5,400,000 shares (the “Shares”) of the registrant’s
common stock, at a per share purchase price of $0.15 per share. At the Closing, the Company received gross proceeds of approximately
$810,000 from the sale of the Shares. The material terms and conditions of the Securities Purchase Agreement and Registration
Rights Agreement are further described in the Company’s current report on Form 8-K filed with the Securities Exchange Commission
on May 1, 2015.

The
Company entered into additional capital leases totaling $13,680 payable to Dell Computers in January, 2015.

 

The
Company is obligated to enter into a performance bond of $2,100,000 (the “Bond”) payable for the benefit of
Dresser-Rand in order to secure performance on delivery of two Power Oxidizer units. The Bond is required within 45 days of the
placement of an order for the Power Oxidizer units.

 

Pursuant
to the Exchange Agreement, the Company granted the April 2014 Investors a right of first refusal to participate in any future
sale of the Company’s equity or equity equivalent securities on a pro rata basis up to 50% of the securities offered in
such sale, from the closing date of the Warrant Exchange (April 17, 2015) until April 16, 2016 except for a registered underwritten
public offering. In the event that the Company engages in a registered underwritten public offering of its common stock and the
offering price per share in such registered offering is more than 85% of the closing sale price of the registrant’s common
stock on the date of pricing of such offering, then the participation right shall be 20% of the securities offered in such registered
offering. Such participation rights are also more fully described in our Current Report on Form 8-K filed with the SEC April 7,
2015 and in Section 4(b)(xvii) of the form of Exchange Agreement attached as Exhibit 10.1 to such Current Report.

 

    	 

    	 

    

 

As
described more fully in Schedule 3(m), at the April Closing of the April 2015 Financing, the Company sold and issued to the Investors,
Notes with an aggregate principal amount of $3,100,000 and Warrants to purchase up to 6,813,186 shares of the Company’s
common stock. The Notes mature on April 23, 2017 and bear an interest rate of 12.00% per annum (which increases to 18% in the
event of default) payable monthly in cash. The Notes are secured by a guaranty by our subsidiary Ener-Core Power, Inc. (“ECP”)
as well as current and future assets of the registrant and ECP (excluding certain intellectual property assets) pursuant to that
certain Pledge and Security Agreement dated April 23, 2015 entered into by the Company for the benefit of the Investors. In addition,
the Note holders have the following rights:

 

	 	●	The
    Notes are convertible under limited circumstances consisting solely of any time following an event of default under the terms
    of the Note (an "Event of Default Conversion Period") or during the period from the consummation of a Qualified
    Public Offering and continuing for thirty (30) days thereafter (a "QPO Conversion Period"). During an Event of Default
    Conversion Period, each holder is entitled to convert any portion of the outstanding principal on their Note, plus any accrued
    and unpaid interest and applicable late payment charges with respect to such principal (collectively, a “Conversion
    Amount”) into shares of the registrant’s common stock. During a QPO Conversion Period, each holder is entitled
    to convert up to 50% of their outstanding principal, and accrued and unpaid interest into common stock. The conversion rate
    shall be determined by dividing (1) the Conversion Amount by (2) a conversion price which shall be: (A) during an Event of
    Default Conversion Period, a price per share equal to 85% of the arithmetic average of the five (5) lowest weighted average
    prices of the Common Stock during the fifteen (15) consecutive trading day period ending on the trading day immediately preceding
    the applicable conversion date, (B) as of any conversion date occurring during a QPO Conversion Period, a price per share
    equal to the offering price to the public of the Common Stock offered for sale by the registrant in such Qualified Public
    Offering and (C) as to any conversion date occurring during a Conversion Period that is both an Event of Default Conversion
    Period and a QPO Conversion Period, the lower of (x) the price set forth in clause (A) and (y) the price set forth in clause
    (B). In addition, during a QPO Conversion Period, if the registrant issues any securities of the registrant directly or indirectly
    convertible, exchangeable or exercisable into Common Stock in connection with a Qualified Public Offering (“QPO Derivative
    Securities”), each holder, automatically and without having to pay any additional consideration to the registrant, shall
    receive the same number of QPO Derivative Securities per share of Common Stock receivable upon such conversion as was received
    by the holders in the applicable Qualified Public Offering. However, in any case, the registrant shall not be permitted to
    effect any conversion if, following such conversion, a holder would beneficially own more than 9.99% of the shares of Common
    Stock after giving effect to such conversion.

 

    	 

    	 

    

 

	 	●	Each
    holder may require the registrant to redeem the Notes at a price equal to 115% of the Conversion Amount being redeemed (a)
    upon the registrant’s default under the Notes, or (b) if the registrant enters into a merger or consolidation, or sell
    or assign all or substantially all of its assets. In addition, at any time from and after October 23, 2016, each holder shall
    have the right, in its sole and absolute discretion, at any time or times, to require that the registrant redeem all or any
    portion of the Conversion Amount of their Note then outstanding at price equal to 100% of the Conversion Amount of the portion
    of the Note being redeemed.

 

At
any time after the issuance of the Notes, other than (i) at any time during which an event of default has occurred and is continuing
or (ii) from the time the registrant publicly announces a Qualified Public Offering through and including the date that is thirty
(30) days immediately following the consummation of such Qualified Public Offering, the registrant has the right to redeem all
or any portion of the Conversion Amount then remaining under the Notes (a “Company Optional Redemption”); provided,
that the aggregate Conversion Amount under Notes being redeemed shall be at least $500,000, or such lesser amount that is then
outstanding under the Notes. The conversion price for such Company Optional Redemption shall be a price equal to 100% of the Conversion
Amount of the Notes being redeemed. See also the Company’s Current Report Form 8-K filed with the SEC on April 23, 2015
and in the exhibits thereto in connection with the April 2015 Financing.

 

The
Company expects to enter into up to $1 million of additional secured financings within the next 12 months consisting of approximately
$500,000 of capital lease financing for the Company’s multi-fuel test facility under construction and approximately $500,000
of secured financing for the 1.75MW power station prototype under development with Dresser-Rand.

                                         of any contract, agreement or instrument, the violation of which, or default under which,
                                         by the other party(ies) to such contract, agreement or instrument could reasonably be

(Internal
Accounting and Disclosure Controls)

 

As
of December 31, 2014, 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).

 

    	 

    	 

    

 

Based
on such evaluation, the disclosure controls and procedures of the Company and the Subsidiary as of December 31, 2014 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, 2014 we did not have accounting and finance staff with sufficient
                                         technical accounting training and experience capable to manage and process the Company’s
                                         derivative equity accounting including stock options and warrants.  In addition,
                                         the Company had 100% turnover during the year of accounting and finance management and
                                         staff.  This turnover resulted in periods of time where there was insufficient
                                         review of internal and external reports and proof of key internal controls. Management
                                         evaluated the impact of our failure to have inadequate technical accounting experience,
                                         coupled with the turnover, on our assessment of our disclosure controls and procedures
                                         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 the not independent.  Between December
                                         1, 2014 and December 31, 2014 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, our audit committee consisted of the Chairman of the
                                         committee only.  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, 2014, 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 2014 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
