(b)
That the Investor, either alone or with the assistance of the Investor’s own professional advisor, has such knowledge and
experience in financial and business matters that the Investor is capable of evaluating the merits and risk of an investment in
the Securities and has the net worth to undertake such risks;

 

(c)
That the Investor has obtained, to the extent the Investor deems necessary, the Investor’s own personal professional advice
with respect to the risks inherent in the investment in the Securities, and the suitability of an investment in the Securities
in light of the Investor’s financial condition and investment needs;

 

(d)
That the Investor believes that an investment in the Securities is suitable for the Investor based upon the Investor’s investment
objectives and financial needs, and the Investor has adequate means for providing for the Investor’s current financial needs
and personal contingencies and has no need for liquidity of investment with respect to the Securities;

 

(e)

Investor deems necessary and a reasonable person would deem necessary, to make an informed investment decision, and has relied

That the Investor recognizes that the Securities as an investment involve a high degree of risk, including, but not limited to,
the risk of economic losses from operations of the Company;

 

(g)

investment in the event of an emergency, or pledge the Securities as collateral for a loan;

 

    	-2-

    	 

    

 

(h)
That the Investor realizes that (i) the purchase of the Securities is a long-term investment; (ii) the purchaser of the Securities
must bear the economic risk of investment for an indefinite period of time because the Securities have not been registered under
the Securities Act or under the securities laws of any state and, therefore, the Securities cannot be resold unless they are subsequently
registered under said laws or exemptions from such registrations are available; and (iii) the transferability of the Securities
requires conformity with the restrictions contained in Section 4 below and legends will be placed on the certificate(s) representing
the Securities, referring to the applicable restrictions on transferability;

 

(i)
That a legend will be placed on the Note, Warrants or other instrument(s) representing the Securities substantially to the following
effect:

in connection with the transactions contemplated by this Agreement.

 

4.
Transfer Restrictions. The Investor has been advised that the Securities have not been registered under the Securities
Act or applicable state securities laws and that the Securities are being offered and sold pursuant to exemptions from such laws
and that the Company’s reliance upon such exemptions is predicated in part on the Investor’s representations as contained

7.
Knowledge and Experience. The Investor further represents and warrants that the Investor has such knowledge and experience
in financial and business matters so as to be capable of evaluating the merits and risks of an investment in the Securities and
protecting the Investor’s own interests in this transaction, and does not desire to utilize the services of any other person
in connection with evaluating such merits and risks.

 

8.
Money Laundering. The Investor further represents and warrants that it is not, nor is any person or entity controlling,
controlled by or under common control with the Investor, a Prohibited Person (as defined below), and that the funds used by the
Investor exclude any funds received or derived from a Prohibited Person. All information provided with respect to the identity
of the Investor is accurate, and all evidence of such identity is genuine. The Investor agrees to provide any information that
may be requested by the Company or any other person with responsibility for implementing measures to prevent money laundering
or terrorist financing to comply with its anti-money laundering program and related responsibilities from time to time. “Prohibited
Person” means a person involved in money laundering or terrorist activities, including those persons or entities
that are included on any relevant lists maintained by the U.S. Treasury Department’s Office of Foreign Assets Control, any
senior foreign political figures, their immediate family members and close associates, and any foreign shell bank.

 

9.
Need for Additional Financing. The Investor acknowledges and understands that the Company may need to raise additional
financing (either through private or public offerings of equity or convertible debt securities of the Company or through loans,
lines of credit and other forms of indebtedness by the Company). The issuance of additional equity or convertible debt securities
will have the effect of reducing the relative interests of the Investor and may require the grant of certain rights, preferences
or privileges superior to those of the Investor. In the event the Company is required to raise additional funds, the Investor
acknowledges and understands that there is no assurance that the Company will be able to obtain the additional funds necessary
on terms favorable to the Company, or at all, and that, if adequate funds are not available or are not available on acceptable
terms, the Company may not be able to continue as a going-concern.

 

10.
Reliance on Representations and Warranties; Changes in Information. The Investor is informed of the significance to the
Company of the foregoing representations, agreements and consents, and they are made with the intention that the Company will
rely on them. The Investor further represents and warrants that the Investor’s representations and warranties do not contain
any untrue statement of material fact or omit to state a material fact necessary in order to make said representations and warranties
not misleading. The Investor further agrees that, if there should be any change in the information provided by the Investor to
the Company (whether pursuant to this Agreement or otherwise), the undersigned will immediately furnish such revised or corrected
information in writing to the Company.

to carry out the provisions of this Agreement and the exhibits hereto and to carry on its business as presently conducted. The
Company is duly qualified to do business and is in good standing as a foreign corporation in all jurisdictions in which the nature

as amended, or of any provision of any mortgage, indenture, contract, lease, agreement, instrument or contract to which it is

adverse effect on the Company. The execution, delivery, and performance of and compliance with this Agreement, and the issuance
and sale of the Securities will not, with or without the passage of time or giving of notice, result in any such material violation,
or be in conflict with or constitute a material default under any such term or provision, or result in the creation of any mortgage,
pledge, lien, encumbrance or charge upon any of the properties or assets of the Company or the suspension, revocation, impairment,
forfeiture or nonrenewal of any permit, license, authorization or approval applicable to the Company, its business or operations

Company enforceable in accordance with their terms.

 

(d)
Compliance with Laws; Permits. The Company is not in violation of any applicable statute, rule, regulation, order or restriction
of any domestic or foreign government or any instrumentality or agency thereof in respect of the conduct of its business or the

condition, operations or prospects of the Company. No governmental orders, permissions, consents, approvals or authorizations
are required to be obtained and no registrations or declarations are required to be filed in connection with the execution and
delivery of this Agreement, except such as have been duly and validly obtained or filed, or with respect to any filings that must

necessary for the conduct of its business as now being conducted by it.

all in accordance with GAAP, expressly subject to fiscal year-end adjustments (the effect of which will not, individually or in

in the respective balance sheets).

    	-13-

    	 

    

 

C.
This Note is convertible into securities of the Company as provided herein.

 

The
following is a statement of the rights of the Holder and certain conditions to which this Note is subject, and to which the Holder,
by the acceptance of this Note, agrees:

 

1.
Definitions. As used in this Note, the following capitalized terms have the following meanings:

 

(a)
“Business Day” means a day (i) other than Saturday or Sunday, and (ii) on which commercial banks are open for
business in the State of California.

 

(b)
“Default Rate” means an interest rate of eighteen percent (18%) per annum.

 

(c)
“Event of Default” has the meaning given in Section 6 hereof.

 

(d)
“Highest Lawful Rate” means the maximum non-usurious rate of interest, as in effect from time to time, which
may be charged, contracted for, reserved, received or collected by the Holder in connection with this Note under applicable law.

 

(e)
“Holder” shall mean the person or entity specified in the introductory paragraph of this Note or any person
or entity who shall at the time be the registered holder of this Note.

 

(f)
“Note” shall mean this 10% Subordinated Convertible Promissory Note (Series O-2).

 

(g)
“Obligations” means all debts, liabilities and obligations of the Company to the Holder under this Note and
the Security Agreement, including all unpaid Principal of this Note, all Interest accrued hereon, and all other amounts payable
by the Company to the Holder hereunder and under the Security Agreement, whether due or to become due, absolute or contingent,
liquidated or unliquidated, determined or undetermined.

 

2.
Interest. Interest shall accrue on all outstanding Principal from the date hereof until paid at a rate of Ten Percent (10%)
per annum (“Interest”). Interest shall be computed on the basis of the actual number of days elapsed and a
year of three hundred sixty (360) days. During the existence of an Event of Default, Interest shall accrue on all outstanding
Principal at the Default Rate.

 

3.
Prepayment. The Principal and Interest may not be prepaid by the Company without the prior written consent of the
Holder.

 

4.
Conversion.

 

(a)
Automatic Conversion. All outstanding principal and accrued interest under the Note will be automatically converted into shares
of common stock of the Company at the closing of a Qualifying Equity Offering, provided such Qualifying Equity Offering closes
prior to the one-year anniversary of issuance of the Note (the “Automatic Conversion Date”), based upon a conversion
price equal to $2.00 per share (the “Conversion Rate”).

 

(b)
No more than five (5) days before the Automatic Conversion Date, the Company shall provide written notification to the Holder
the Qualifying Equity Offering will be closing, as well as a description of the number of shares of common stock to be issued
to Holder based upon the then outstanding principal and accrued interest under the Note divided by the Conversion Rate. At the
closing of the Qualifying Equity Financing, the Company shall issue instructions to the transfer agent to issue the applicable
number of shares of common stock to Holder.

 

    	-14-

    	 

    

 

(c)
Voluntary Conversion. The Holder may, at any time following the issuance of this Note and prior to the Closing of a Qualifying
Equity Financing, convert all or some of the outstanding principal and accrued interest under this Note at a conversion price
equal to $2.00 per share (the “Voluntary Conversion”). To effectuate the conversion, Holder shall complete
and execute the Notice of Conversion attached hereto as Exhibit A attached hereto and return it along with the original Note to
the Company at its principal place of business. For interest calculation purposes, the Holder will accrue interest on this Note
through the date the Notice of Conversion is received by the Company, upon which the Note will be converted into shares of common
stock and the Company will issue instructions to the transfer agent to issue the applicable number of shares of common stock to
Holder.

 

(d)
If the Company shall at any time from the date hereof through the repayment of this Note in full or the earlier conversion in
full hereof, by reclassification or otherwise, change the Company’s common stock into the same or a different number of
securities of any class or classes, or effect a split or reverse split of the Company’s common stock, this Note, as to the
unpaid Principal and Interest, shall thereafter be deemed to evidence the right to be issued (upon the conversion of this Note)
an adjusted number of shares of common stock as would have been issuable as a result of such change with respect to the Company’s
common stock if the Holder held such shares of common stock prior to such change. Whenever any event referenced in the first sentence
of this subsection shall become effective or be earlier approved by the Board of Directors of the Company, the Company shall promptly
mail by registered or certified mail, return receipt requested, to the Holder of this Note notice of such adjustment or adjustments
setting forth the adjustment to the Conversion Rate, and setting forth a brief statement of the facts requiring such adjustment
and setting forth the computation by which such adjustment was made. Such notice, in the absence of manifest error, shall be conclusive
evidence of the correctness of such adjustment.

 

(e)
The Company covenants that until the repayment in full of this Note or the earlier conversion in full hereof, the Company will
reserve from its respective authorized and unissued shares of common stock a sufficient number of shares, free of preemptive rights,
to provide for the issuance of the shares of common stock upon the full conversion of this Note. The Company is required to have
authorized and reserved such number of shares of Company common stock as is actually issuable upon full conversion of the Note
and exercise of the detachable common stock purchase warrant (“Warrant”) that are included with the purchase of the
Note that are exercisable into that number of shares of common stock equal to the following formula: 100% of the original principal
amount of the Note, divided by $3.00 per share. The Company represents that the shares of common stock (i) into which the Notes
may be converted, and (ii) issuable upon exercise of the Warrant may be exercised, shall be duly and validly issued, fully paid,
and nonassessable. In addition, if the Company shall issue any securities or make any change to its capital structure which would
change the number of shares issuable upon conversion of the Note and exercise of the Warrant, then in such event the Company shall,
at the same time make proper provision so that thereafter there shall be a sufficient number of shares of common stock authorized
and reserved, free from preemptive rights, for conversion of the Note and exercise of the Warrant. The Company agrees that its
issuance of this Note shall constitute full authority to the respective officers and agents of the Company who are charged with
the duty of executing certificates, if any, to execute and issue the necessary shares of common stock in accordance with the terms
and conditions of this Note relating to conversion of the Note.

 

(f)
Upon any partial conversion of this Note pursuant to Section 3(c), a new Note containing the same date, terms, and provisions
shall, at the request of the Holder, be issued by the Company to the Holder for the Principal balance of this Note and the Interest
which shall not have theretofore been converted or paid.

 

    	-15-

    	 

    

 

(g)
No fractional shares of common stock will be issued upon conversion, but the number of such shares issuable shall be rounded to
the nearest whole share.

 

(h)
Nothing contained in this Note shall be construed as conferring upon the Holder or any other person or entity the right to vote
or to consent or to receive notice as a shareholder in respect of meeting of shareholders for the election of directors of the
Company or any other matters or any rights whatsoever as a shareholder of the Company; and no dividends shall be payable or accrued
in respect of this Note.

 

5.
Highest Lawful Rate. Notwithstanding any provision to the contrary contained herein, if during any period for which Interest
is computed hereunder, the amount of Interest computed on the basis provided for in this Note, together with all fees, charges
and other payments which are treated as interest under applicable law, as provided for herein or in any other document executed
in connection herewith, would exceed the amount of such Interest computed on the basis of the Highest Lawful Rate, the Company
shall not be obligated to pay, and the Holder shall not be entitled to charge, collect, receive, reserve or take Interest in excess
of the Highest Lawful Rate, and during any such period the Interest payable hereunder shall be computed on the basis of the Highest
Lawful Rate.

 

6.
Make Good Provision. During the term of this Note, including at any time prior to an Automatic Conversion or Voluntary
Conversion of this Note by Holder, if the Company elects to undertake another convertible debt financing on terms more favorable
to the terms of the Note and the Warrant, then in such event the terms of the Note and the Warrant shall be modified to reflect
the more favorable convertible debt financing terms.

 

7.
Events of Default. Any of the following events which shall occur shall constitute an “Event of Default”:

 

(a)
the Company shall fail to pay when due any amount of principal or interest hereunder or other amount payable hereunder or under
the Security Agreement, where such failure continues for five (5) days after receipt of written notice from Holder specifying
such failure; or

 

(b)

take or approve any action for the purpose of effecting any of the foregoing; or

 

(c)

(d)
a default or event of default under any agreement of the Company shall occur that gives the holder of any other indebtedness for
borrowed money of the Company the right to accelerate the maturity of such indebtedness (subject to any applicable cure periods
set forth therein, if any); or

 

(e)
the Company shall fail to observe or perform any other covenant, obligation, condition or agreement contained in this Note or
the Security Agreement and (i) such failure shall continue for fifteen (15) days, or (ii) if such failure is not curable within
such fifteen (15) day period, but is reasonably capable of cure within thirty (30) days, either (A) such failure shall continue

initial fifteen (15) day period; or

 

(f)
any representation or warranty made or furnished by or on behalf of Company to Holder in writing in connection with this Note

Upon
the occurrence of any Event of Default, (x) the Holder may at any time declare all unpaid Obligations to be immediately due and
payable without presentment, demand, protest or any other notice of any kind, all of which are hereby expressly waived by the
Company; (y) the Holder may exercise all rights and remedies available to the Holder hereunder and under the Security Agreement
and applicable law, and (z) in the case of an Event of Default described in Section 7(b) or 7(c), all unpaid Obligations

all of which are hereby expressly and irrevocably waived by the Company.

 

8.
Successors and Assigns. Subject to the restrictions on transfer described in Section 10, the rights and obligations
of the Company and the Holder hereunder shall be binding upon and inure to the benefit of the successors, assigns, heirs, administrators
and transferees of the parties. Due to the reliance by the Company on the exemption from registration provided by Rule 506 of
Regulation D, as promulgated pursuant to the Securities Act, and the representation by Holder to the Company that Holder is an
“accredited investor” as such term is defined by Rule 501(a) of Regulation D, no assignment of this Note shall be
made to any person who is not an “accredited investor”, where any assignment or transfer of this Note, or any attempt
thereof, shall be null and void.

 

9.
Amendments and Waivers. This Note may not be amended or modified, nor may any of its terms be waived, except by written
instruments signed by the Company and Holder. Each waiver or consent under any provision hereof shall be effective only in the
specific instances for the purpose for which given.

 

10.

or on behalf of the Company. Prior to presentation of this Note for registration of transfer, the Company shall treat the registered
Holder hereof as the owner and the Holder of this Note for the purpose of receiving all payments of Principal and Interest hereon
and for all other purposes whatsoever, whether or not this Note shall be overdue and the Company shall not be affected by notice
to the contrary.

 

11.
Assignment or Delegation by the Company. Neither this Note nor any of the rights, interests or obligations hereunder may
be assigned or delegated in whole or in part by the Company without the prior written consent of Holder.

 

12.
Notices. Except as otherwise provided herein, all notices, requests, demands, consents, instructions or other communications
to or upon the Company or Holder under this Note shall be in writing and mailed or delivered to each party to its address set
forth in the Security Agreement (or to such other address as the recipient of any notice shall have notified the other in writing).
All such notices and communications shall be effective (a) when sent by a commercially recognized means of overnight delivery
providing confirmation of receipt, on the business day following the deposit with such service; (b) when mailed, by registered
or certified mail, first class postage prepaid and addressed as aforesaid through the United States Postal Service, upon receipt;
and (c) when delivered by hand, upon delivery.

13.
Expenses; Waivers. If action is instituted to collect this Note, the Company promises to pay on demand all costs and expenses,
including reasonable attorneys’ fees and costs, incurred in connection with such action. The Company hereby waives notice
of default, presentment or demand for payment, protest or notice of nonpayment or dishonor and all other notices or demands relative
to this instrument.

 

14.
Further Assurance. Each party shall execute, acknowledge, deliver, file, notarize and register (at its own expense) all
documents, instruments, certificates, agreements and assurances and provide all information and take or forbear from all such
action as the other party may reasonably deem necessary or appropriate to achieve the purposes of the Note or satisfy the obligations
of the Company hereunder.

 

15.
Severability. Whenever possible, each provision of this Note shall be interpreted in such manner as to be effective and
valid under all applicable laws and regulations. If, however, any provision of this Note shall be prohibited by or be invalid
under any such law or regulation in any jurisdiction, it shall, as to such jurisdiction, be deemed modified to conform to the
minimum requirements of such law or regulation, or, if for any reason it is not deemed so modified, it shall be ineffective and
invalid only to the extent of such prohibition or invalidity without affecting the remaining provisions of this Note, or the validity
or effectiveness of such provision in any other jurisdiction.

 

16.
Cumulative Rights, etc. The rights, powers and remedies of Holder under this Note and the Security Agreement shall be in
addition to all rights, powers and remedies given to Holder by virtue of any applicable law, rule or regulation of any governmental
authority, the Security Agreement or any other agreement, all of which rights, powers, and remedies shall be cumulative and may
be exercised successively or concurrently without impairing Holder’s rights hereunder. The Company waives any right to require
Holder to proceed against any person or entity or to exhaust any collateral or to pursue any remedy in Holder’s power.

 

17.
No Waiver. No course of dealing between the Company and the Holder or any delay on the part of the Holder in exercising
any rights or remedies shall operate as a waiver of any such right or remedy of the Holder.

 

18.
Construction. Each of the Security Agreement and this Note is the result of negotiations among, and has been reviewed by,
the Company, Holder and their respective counsel. Accordingly, this Note and the Security Agreement shall be deemed to be the
product of all parties hereto, and no ambiguity shall be construed in favor of or against the Company or Holder.

 

19.
Other Interpretive Provisions. References in this Note and the Security Agreement to any document, instrument or agreement
(a) includes all exhibits, schedules and other attachments thereto, (b) includes all documents, instruments or agreements issued
or executed in replacement thereof, and (c) means such document, instrument or agreement, or replacement or predecessor thereto,
as amended, modified and supplemented from time to time and in effect at any given time. The words “hereof,” “herein”
and “hereunder” and words of similar import when used in this Note or the Security Agreement refer to this Note or
the Security Agreement, as the case may be, as a whole and not to any particular provision of this Note or the Security Agreement,
as the case may be. The words “include” and “including” and words of similar import when used in this
Note or the Security Agreement shall not be construed to be limiting or exclusive.

BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEVADA, WITHOUT REGARD TO THE CONFLICTS OF LAW RULES OF
THE STATE OF NEVADA OR OF ANY OTHER JURISDICTION. THE HOLDER HEREBY IRREVOCABLY AND UNCONDITIONALLY SUBMITS TO THE NON-EXCLUSIVE
JURISDICTION OF THE COURTS OF THE STATE OF CALIFORNIA. THE HOLDER AGREES THAT ALL ACTIONS OR PROCEEDINGS ARISING OUT OF OR RELATING
TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY MUST BE LITIGATED EXCLUSIVELY IN ANY SUCH STATE OR FEDERAL COURT, AND

THE
SECURITIES REPRESENTED BY THIS WARRANT CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS
AMENDED (THE “SECURITIES ACT”), OR ANY APPLICABLE STATE SECURITIES LAWS, AND MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED
OR HYPOTHECATED OR OTHERWISE TRANSFERRED IN THE ABSENCE OF A REGISTRATION STATEMENT IN EFFECT WITH RESPECT TO THE SHARES UNDER
THE SECURITIES ACT OR AN EXEMPTION FROM THE SECURITIES ACT. ANY SUCH TRANSFER MAY ALSO BE SUBJECT TO COMPLIANCE WITH APPLICABLE
STATE SECURITIES LAWS AND THE LAWS OF OTHER APPLICABLE JURISDICTIONS.

 

	W-____
    	COMMON
    STOCK PURCHASE WARRANT

 

For
the Purchase of

_______________
Shares

of
Common Stock, $0.001 par value 

of 

QuantumSphere,
Inc.,

A
Nevada Corporation

 

For
value received, __________________________ (the “Holder”), or Holder’s assigns, is entitled to, for a
period of five (5) years from the date of issuance (the “Exercise Period”), exercise this Common Stock Purchase Warrant
(the “Warrant”) to purchase and be issued that number of fully paid and nonassessable shares of the common stock,
$0.001 par value (the “Common Stock”), of QuantumSphere, Inc., a Nevada corporation (the “Company”), represented
by 100% of the face value of the 10% Subordinated Convertible Promissory Note (Series O-2) (the “Note”) purchased
by Holder from the Company divided by $3.00 per share (“Exercise Price”).

 

1.
Exercise of Warrant. This Warrant may be exercised in whole or in part, from time to time, during the Exercise Period,
by presentation and surrender hereof to the Company, with the Notice of Exercise annexed hereto duly executed and accompanied
by payment by bank check or wire transfer of the Exercise Price for the number of shares specified in such form, together with
all federal and state taxes applicable upon such exercise, if any. If this Warrant should be exercised in part only, the Company
shall, upon surrender of this Warrant for cancellation, execute and deliver a new Warrant evidencing the right of the Holder to
purchase the balance of the shares purchasable hereunder. Upon receipt by the Company of this Warrant and the Exercise Price at
the office of the Company, in proper form for exercise, the Holder shall be deemed to be the holder of record of the shares of
Common Stock issuable upon such exercise, notwithstanding that certificates representing such shares of Common Stock shall not
then be actually delivered to the Holder. If the subscription rights represented hereby shall not be exercised at or before 5:00
P.M., Pacific Time, on the expiration date specified above, this Warrant shall become void and without further force or effect,
and all rights represented hereby shall cease and expire.

 

2.
Call Provision. The Company may call the Warrant at any time if, for a period of ten (10) consecutive trading days, the
average closing bid price of the Company’s Common Stock is $3.60 or more (as reported by a national securities exchange
or the OTCQB), upon providing written notice to Holder (the “Redemption Notice”) of its intention to redeem the Warrant.
The Holder shall have a period of thirty (30) days to exercise the Warrant from the date of the Redemption Notice (the “Redemption
Notice Date”). The Holder may exercise this Warrant, including any portion subject to a Redemption Notice, at any time and
from time to time during the period from the Redemption Notice Date through the date on which the redemption price for such Warrants
is paid by the Company (and thereafter if such redemption price is not paid), and the Company shall honor all tendered exercises
of the Warrant during such period. All Redemption Notices under this Section 2 shall be irrevocable. In the event the Warrant
is not exercised in full during the 30-day period, then in such event the Company may redeem the Warrant, at a redemption price
equal to $0.01 per share of Common Stock.

 

    	-23-

    	 

    

 

3.
Rights of the Holder. Prior to exercise of this Warrant, the Holder shall not, by virtue hereof, be entitled to any rights
of a shareholder in the Company, either at law or equity, and the rights of the Holder are limited to those expressed in this
Warrant and are not enforceable against the Company except to the extent set forth herein.

 

4.
Adjustment in Number of Shares.

 

(A)
Adjustment for Reclassifications. In case at any time, or from time to time, after the date of issue (“Issue Date”),
the holders of the Common Stock of the Company (or any shares of stock or other securities at the time receivable upon the exercise
of this Warrant) shall have received, or, on or after the record date fixed for the determination of eligible stockholders, shall
have become entitled to receive, without payment therefore, other or additional stock or other securities or property (including
cash) by way of stock-split, spinoff, reclassification, combination of shares or similar corporate rearrangement (exclusive of
any stock dividend of its or any subsidiary’s capital stock), then and in each such case the Holder(s) of this Warrant,
upon the exercise hereof as provided in Section 1, shall be entitled to receive the amount of stock and other securities and property
which such Holder(s) would hold on the date of such exercise if on the Issue Date they had been the holder of record of the number
of shares of Common Stock of the Company called for on the face of this Warrant and had thereafter, during the period from the
Issue Date, to and including the date of such exercise, retained such shares and/or all other or additional stock and other securities
and property receivable by them as aforesaid during such period, giving effect to all adjustments called for during such period.
In the event of a declaration of a dividend payable in shares of any equity security of a subsidiary of the Company, then the
Company may cause to be issued a warrant to purchase shares of the subsidiary (“Springing Warrant”) in an amount equal
to such number of shares of the subsidiary’s securities to which the Holders would have been entitled, but conditioned upon
the exercise of this Warrant as a prerequisite to receiving the shares issuable pursuant to the Springing Warrant.

 

(B)
Adjustment for Reorganization, Consolidation, Merger. In case of any reorganization of the Company (or any other corporation
the stock or other securities of which are at the time receivable on the exercise of this Warrant) after the Issue Date, or in
case, after such date, the Company (or any such other corporation) shall consolidate with or merge into another corporation or
convey all or substantially all of its assets to another corporation, then and in each such case the Holder(s) of this Warrant,
upon the exercise hereof as provided in Section 1, at any time after the consummation of such reorganization, consolidation, merger
or conveyance, shall be entitled to receive, in lieu of the stock or other securities and property receivable upon the exercise
of this Warrant prior to such consummation, the stock or other securities or property to which such Holder(s) would be entitled
had the Holders exercised this Warrant immediately prior thereto, all subject to further adjustment as provided herein; in each
such case, the terms of this Warrant shall be applicable to the shares of stock or other securities or property receivable upon
the exercise of this Warrant after such consummation.

 

5.
Officer’s Certificate. Whenever the number of shares of Common Stock issuable upon exercise of this Warrant or the
Exercise Price shall be adjusted as required by the provisions hereof, the Company shall forthwith file in the custody of its
Secretary at its principal office, an officer’s certificate showing the adjusted number of shares of Common Stock or Exercise
Price determined as herein provided and setting forth in reasonable detail the facts requiring such adjustment. Each such officer’s
certificate shall be made available at all reasonable times for inspection by the Holder(s) and the Company shall, forthwith after
each such adjustment, deliver a copy of such certificate to the Holder(s). Such certificate shall be conclusive as to the correctness
of such adjustment.

 

    	-24-

    	 

    

 

6.
Restrictions on Transfer. Certificates for the shares of Common Stock to be issued upon exercise of this Warrant shall
bear the following legend:

 

THE
SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED
(THE “SECURITIES ACT”), OR ANY APPLICABLE STATE SECURITIES LAWS, AND MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR
HYPOTHECATED OR OTHERWISE TRANSFERRED IN THE ABSENCE OF A REGISTRATION STATEMENT IN EFFECT WITH RESPECT TO THE SHARES UNDER THE
SECURITIES ACT OR AN EXEMPTION FROM THE SECURITIES ACT. ANY SUCH TRANSFER MAY ALSO BE SUBJECT TO COMPLIANCE WITH APPLICABLE STATE
SECURITIES LAWS AND THE LAWS OF OTHER APPLICABLE JURISDICTIONS.

 

The
Holder, by acceptance hereof, agrees that, absent an effective registration statement under the Securities Act of 1933, as amended
(the “Act”), covering the disposition of this Warrant or the Common Stock issued or issuable upon exercise hereof,
such Holder(s) will not sell or transfer any or all of this Warrant or such Common Stock without first providing the Company with
an opinion of counsel reasonably satisfactory to the Company to the effect that such sale or transfer will be exempt from the
registration and prospectus delivery requirements of the Act. The Holder agrees that the certificates evidencing the Warrant and
Common Stock which will be delivered to the Holder by the Company shall bear substantially the legend set forth above in this
Section 6. The Holder of this Warrant, at the time all or a portion of such Warrant is exercised, agrees to make such written
representations to the Company as counsel for the Company may reasonably request, in order that the Company may be reasonably
satisfied that such exercise of the Warrant and consequent issuance of Common Shares will not violate the registration and prospectus
delivery requirements of the Act, or other applicable state securities laws.

 

7.
Loss or Mutilation. Upon receipt by the Company of evidence satisfactory to it (in the exercise of reasonable discretion)
of the ownership of and the loss, theft, destruction or mutilation of any Warrant and (in the case of loss, theft or destruction)
of indemnity satisfactory to it (in the exercise of reasonable discretion), and (in the case of mutilation) upon surrender and
cancellation thereof, the Company will execute and deliver in lieu thereof a new Warrant of like tenor.

 

8.
Reservation of Common Stock. The Company shall at all times reserve and keep available for issue upon the exercise of the
Warrant such number of its authorized but unissued shares of Common Stock as will be sufficient to permit the exercise in full
of all outstanding Warrants.

 

9.
Notices. All notices and other communications from the Company to the Holder of this Warrant shall be mailed by first class
registered or certified mail, postage prepaid, to the address furnished to the Company in writing by the Holder.

 

10.
Change; Waiver. Neither this Warrant nor any term hereof may be changed, waived, discharged or terminated orally but only
by an instrument in writing signed by the party against which enforcement of the change, waiver, discharge or termination is sought.

 

11.
Law Governing. This Warrant shall be construed and enforced in accordance with and governed by the laws of Nevada.

REGISTRATION
RIGHTS AGREEMENT

 

THIS
REGISTRATION RIGHTS AGREEMENT (the “Agreement”) is dated May 28, 2015 by and between QuantumSphere, Inc., a
Nevada corporation (the “Company”), and each of the signatories hereto (collectively, the “Investor”).

 

RECITALS

 

WHEREAS,
to induce the Investor to invest in the Offering described in the accompanying Note Purchase Agreement, the Company has agreed
to provide certain registration rights under the Securities Act of 1933, as amended, and the rules and regulations thereunder,
or any similar successor statute (collectively, the “Securities Act”), and applicable state securities laws.

 

NOW,
THEREFORE, in consideration of the premises and the mutual covenants contained herein and other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, the Company and the Investor hereby agree as follows:

 

AGREEMENT

 

1.DEFINITIONS.

 

As
used in this Agreement, the following terms shall have the following meanings:

 

a.“Person”
means a corporation, a limited liability company, an association, a partnership, an organization, a business, an individual, a
governmental or political subdivision thereof or a governmental agency.

 

b.“Register,”
“registered,” and “registration” refer to a registration effected by preparing and filing one or more
Registration Statements (as defined below) in compliance with the Securities Act and pursuant to Rule 415 under the Securities
Act or any successor rule providing for offering securities on a continuous or delayed basis (“Rule 415”), and the
declaration or ordering of effectiveness of such Registration Statement(s) by the United States Securities and Exchange Commission
(the “SEC”).

 

c.“Registrable
Securities” means shares of common stock issuable to Investor upon conversion of the 10% Subordinated Convertible Promissory
Notes in the Offering (the “Shares”), and the shares of common stock issuable upon exercise of the warrants
issued to Investor pursuant to the Offering (“Warrant Shares”).

 

d.“Registration
Statement” means a registration statement filed with the SEC, pursuant to the Securities Act, that includes the Registrable
Securities.

 

2.REGISTRATION.

 

a.Piggyback
Registration Rights. Investor shall be afforded unlimited piggyback registration rights with respect to the Shares and Warrant
Shares. The Company shall notify the Investor in writing no less than fifteen (15) calendar days prior to the filing of any Registration
Statement on Form S-1 or S-3 of its intention to file such registration statement with the Securities and Exchange Commission.
The Investor shall have a period of ten (10) calendar days to notify the Company of its intention to have its Registrable Securities
included in such Registration Statement.

 

    	-37-

    	 

    

 

b.Sufficient
Number of Shares Registered. The number of shares of common stock included in a Registration Statement filed pursuant to Section
2(a) shall be sufficient to cover all of the Registrable Securities.

 

3.RELATED
OBLIGATIONS.

 

a.The
Company shall keep the Registration Statement effective pursuant to Rule 415 at all times until the date on which the Investor
shall have sold all the Registrable Securities covered by such Registration Statement (the “Registration Period”),
which Registration Statement (including any amendments or supplements thereto and prospectuses contained therein) shall not contain
any untrue statement of a material fact or omit to a material fact required to be stated therein, or necessary to make the statements
therein, in light of the circumstances in which they were made, not misleading.

 

b.The
Company shall prepare and file with the SEC such amendments (including post-effective amendments) and supplements to a Registration
Statement and the prospectus used in connection with such Registration Statement, which prospectus is to be filed pursuant to
Rule 424 promulgated under the Securities Act, as may be necessary to keep such Registration Statement effective at all times
during the Registration Period, and, during such period, comply with the provisions of the Securities Act with respect to the
disposition of all Registrable Securities of the Company covered by such Registration Statement until such time as all of such
Registrable Securities shall have been disposed of in accordance with the intended methods of disposition by the seller or sellers
thereof as set forth in such Registration Statement. In the case of amendments and supplements to a Registration Statement which
are required to be filed pursuant to this Agreement (including pursuant to this Section 3(b)) by reason of the Company’s
filing a report on Form 10-K, Form 10-Q or Form 8-K or any analogous report under the Securities Exchange Act of 1934, as amended
(the “Exchange Act”), the Company shall have incorporated such report by reference into the Registration Statement,
if applicable, or shall file such amendments or supplements with the SEC on the same day on which the Exchange Act report is filed
which created the requirement for the Company to amend or supplement the Registration Statement.

 

c.The
Company shall furnish to the Investor without charge, (i) at least one (1) copy of such Registration Statement as declared effective
by the SEC and any amendment(s) thereto, including financial statements and schedules, all documents incorporated therein by reference,
all exhibits and each preliminary prospectus, (ii) one (1) copy of the final prospectus included in such Registration Statement
and all amendments and supplements thereto (or such other number of copies as such Investor may reasonably request) and (iii)
such other documents as such Investor may reasonably request from time to time in order to facilitate the disposition of the Registrable
Securities owned by such Investor.

 

d.The
Company shall use its best efforts to (i) register and qualify the Registrable Securities covered by a Registration Statement
under such other securities or “blue sky” laws of such jurisdictions in the United States as the Investor reasonably
requests, (ii) prepare and file in those jurisdictions, such amendments (including post-effective amendments) and supplements
to such registrations and qualifications as may be necessary to maintain the effectiveness thereof during the Registration Period,
(iii) take such other actions as may be necessary to maintain such registrations and qualifications in effect at all times during
the Registration Period, and (iv) take all other actions reasonably necessary or advisable to qualify the Registrable Securities
for sale in such jurisdictions; provided, however, that the Company shall not be required in connection therewith or as a condition
thereto to (w) make any change to its certificate of incorporation or by-laws, (x) qualify to do business in any jurisdiction
where it would not otherwise be required to qualify but for this Section 3(d), (y) subject itself to general taxation in any such
jurisdiction, or (z) file a general consent to service of process in any such jurisdiction. The Company shall promptly notify
the Investor of the receipt by the Company of any notification with respect to the suspension of the registration or qualification
of any of the Registrable Securities for sale under the securities or “blue sky” laws of any jurisdiction in the United
States or its receipt of actual notice of the initiation or threat of any proceeding for such purpose.

 

    	-38-

    	 

    

 

e.As
promptly as practicable after becoming aware of such event or development, the Company shall notify the Investor in writing of
the happening of any event as a result of which the prospectus included in a Registration Statement, as then in effect, includes
an untrue statement of a material fact or omission to state a material fact required to be stated therein or necessary to make
the statements therein, in light of the circumstances under which they were made, not misleading (provided that in no event shall
such notice contain any material, nonpublic information), and promptly prepare a supplement or amendment to such Registration
Statement to correct such untrue statement or omission, and deliver one (1) copy of such supplement or amendment to each Investor.
The Company shall also promptly notify the Investor in writing (i) when a prospectus or any prospectus supplement or post-effective
amendment has been filed, and when a Registration Statement or any post-effective amendment has become effective (notification
of such effectiveness shall be delivered to the Investor by facsimile on the same day of such effectiveness), (ii) of any request
by the SEC for amendments or supplements to a Registration Statement or related prospectus or related information, and (iii) of
the Company’s reasonable determination that a post-effective amendment to a Registration Statement would be appropriate.

 

f.The
Company shall use its best efforts to prevent the issuance of any stop order or other suspension of effectiveness of a Registration
Statement, or the suspension of the qualification of any of the Registrable Securities for sale in any jurisdiction within the
United States of America and, if such an order or suspension is issued, to obtain the withdrawal of such order or suspension at
the earliest possible moment and to notify the Investor of the issuance of such order and the resolution thereof or its receipt
of actual notice of the initiation or threat of any proceeding for such purpose.

 

g.At
the reasonable request of the Investor, the Company shall furnish to the Investor, on the date of the effectiveness of the Registration
Statement and thereafter from time to time on such dates as the Investor may reasonably request (i) a letter, dated such date,
from the Company’s independent certified public accountants in form and substance as is customarily given by independent
certified public accountants to underwriters in an underwritten public offering, if any, and (ii) an opinion, dated as of such
date, of counsel representing the Company for purposes of such Registration Statement, in form, scope and substance as is customarily
given in an underwritten public offering (if applicable), addressed to the Investor.

 

h.The
Company shall hold in confidence and not make any disclosure of information concerning the Investor provided to the Company unless
(i) disclosure of such information is necessary to comply with federal or state securities laws, (ii) the disclosure of such information
is necessary to avoid or correct a misstatement or omission in any Registration Statement, (iii) the release of such information
is ordered pursuant to a subpoena or other final, non-appealable order from a court or governmental body of competent jurisdiction,
or (iv) such information has been made generally available to the public other than by disclosure in violation of this Agreement
or any other agreement. The Company agrees that it shall, upon learning that disclosure of such information concerning the Investor
is sought in or by a court or governmental body of competent jurisdiction or through other means, give prompt written notice to
the Investor and allow the Investor, at the Investor’s expense, to undertake appropriate action to prevent disclosure of,
or to obtain a protective order for, such information.

 

    	-39-

    	 

    

 

i.The
Company shall use its best efforts either to cause all the Registrable Securities covered by a Registration Statement (i) to be
listed on each securities exchange on which securities of the same class or series issued by the Company are then listed, if any,
if the listing of such Registrable Securities is then permitted under the rules of such exchange or to secure the inclusion for
quotation on the Over-The Counter Bulletin Board for such Registrable Securities. The Company shall pay all fees and expenses
in connection with satisfying its obligation under this Section 3(i).

 

j.The
Company shall cooperate with the Investor to the extent applicable, to facilitate the timely preparation and delivery of certificates
(not bearing any restrictive legend) representing the Registrable Securities to be offered pursuant to a Registration Statement
and enable such certificates to be in such denominations or amounts, as the case may be, as the Investor may reasonably request
and registered in such names as the Investor may request; provided, however, delivery of such certificates shall not be made until
such Registration Statement is declared effective by the SEC and all applicable state securities regulatory agencies.

 

k.The
Company shall use its best efforts to cause the Registrable Securities covered by the applicable Registration Statement to be
registered with or approved by such other governmental agencies or authorities as may be necessary to consummate the disposition
of such Registrable Securities.

 

l.The
Company shall otherwise use its best efforts to comply with all applicable rules and regulations of the SEC in connection with
any registration hereunder.

 

m.Within
two (2) business days after a Registration Statement which covers Registrable Securities is ordered effective by the SEC, the
Company shall deliver, and shall cause legal counsel for the Company to deliver, to the transfer agent for such Registrable Securities
(with copies to the Investor) confirmation that such Registration Statement has been declared effective by the SEC in the form
attached hereto as Exhibit 1.

 

n.The
Company shall take all other reasonable actions necessary to expedite and facilitate disposition by the Investors of Registrable
Securities pursuant to a Registration Statement.

 

4.OBLIGATIONS
OF THE INVESTOR.

 

The
Investor agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section
3(f) or the first sentence of 3(e), the Investor will immediately discontinue disposition of Registrable Securities pursuant to
any Registration Statement(s) covering such Registrable Securities until the Investor’s receipt of a copy of the supplemented
or amended prospectus contemplated by Section 3(e) or receipt of notice that no supplement or amendment is required. Notwithstanding
anything to the contrary, the Company shall cause its transfer agent to deliver unlegended certificates for shares of Common Stock
to a transferee of the Investor in accordance with the terms of the Offering in connection with any sale of Registrable Securities
with respect to which the Investor has entered into a contract for sale prior to the Investor’s receipt of a notice from
the Company of the happening of any event of the kind described in Section 3(f) or the first sentence of 3(e) and for which the
Investor has not yet settled. All selling expenses relating to the Registrable Securities shall be borne exclusively by the Investor.

 

    	-40-

    	 

    

 

5.EXPENSES
OF REGISTRATION.

 

All
expenses incurred in connection with registrations, filings or qualifications pursuant to Sections 2 and 3, including, without
limitation, all registration, listing and qualifications fees, printers, legal and accounting fees shall be paid by the Company.

 

6.INDEMNIFICATION.

 

With
respect to Registrable Securities which are included in a Registration Statement under this Agreement:

 

a.To
the fullest extent permitted by law, the Company will, and hereby does, indemnify, hold harmless and defend the Investor, the
directors, officers, partners, employees, agents, representatives of, and each Person, if any, who controls the Investor within
the meaning of the Securities Act or the Exchange Act (each, an “Indemnified Person”), against any losses, claims,
damages, liabilities, judgments, fines, penalties, charges, costs, reasonable attorneys’ fees, amounts paid in settlement
or expenses, joint or several (collectively, “Claims”) incurred in investigating, preparing or defending any action,
claim, suit, inquiry, proceeding, investigation or appeal taken from the foregoing by or before any court or governmental, administrative
or other regulatory agency, body or the SEC, whether pending or threatened, whether or not an indemnified party is or may be a
party thereto (“Indemnified Damages”), to which any of them may become subject insofar as such Claims (or actions
or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon: (i) any untrue statement
or alleged untrue statement of a material fact in a Registration Statement or any post-effective amendment thereto or in any filing
made in connection with the qualification of the offering under the securities or other “blue sky” laws of any jurisdiction
in which Registrable Securities are offered (“Blue Sky Filing”), or the omission or alleged omission to state a material
fact required to be stated therein or necessary to make the statements therein not misleading; (ii) any untrue statement or alleged
untrue statement of a material fact contained in any final prospectus (as amended or supplemented, if the Company files any amendment
thereof or supplement thereto with the SEC) or the omission or alleged omission to state therein any material fact necessary to
make the statements made therein, in light of the circumstances under which the statements therein were made, not misleading;
or (iii) any violation or alleged violation by the Company of the Securities Act, the Exchange Act, any other law, including,
without limitation, any state securities law, or any rule or regulation there under relating to the offer or sale of the Registrable
Securities pursuant to a Registration Statement (the matters in the foregoing clauses (i) through (iii) being, collectively, “Violations”).
The Company shall reimburse the Investor and each such controlling person promptly as such expenses are incurred and are due and
payable, for any legal fees or disbursements or other reasonable expenses incurred by them in connection with investigating or
defending any such Claims. Notwithstanding anything to the contrary contained herein, the indemnification agreement contained
in this Section 6(a): (x) shall not apply to a Claim by an Indemnified Person arising out of or based upon a Violation which occurs
in reliance upon and in conformity with information furnished in writing to the Company by such Indemnified Person expressly for
use in connection with the preparation of the Registration Statement or any such amendment thereof or supplement thereto; (y)
shall not be available to the extent such Claim is based on a failure of the Investor to deliver or to cause to be delivered the
prospectus made available by the Company, if such prospectus was timely made available by the Company pursuant to Section 3(e);
and (z) shall not apply to amounts paid in settlement of any Claim if such settlement is effected without the prior written consent
of the Company, which consent shall not be unreasonably withheld. Such indemnity shall remain in full force and effect regardless
of any investigation made by or on behalf of the Indemnified Person. In connection with a Registration Statement, the Investor
agrees to indemnify, hold harmless and defend, to the same extent and in the same manner as is set forth in this Section 6(a),
the Company, each of its directors, each of its officers who signs the Registration Statement and each Person, if any, who controls
the Company within the meaning of the Securities Act or the Exchange Act (each an “Indemnified Party”), against any
Claim or Indemnified Damages to which any of them may become subject, under the Securities Act, the Exchange Act or otherwise,
insofar as such Claim or Indemnified Damages arise out of or is based upon any Violation, in each case to the extent, and only
to the extent, that such Violation occurs in reliance upon and in conformity with written information furnished to the Company
by the Investor expressly for use in connection with such Registration Statement; and, subject to Section 6(d), the Investor will
reimburse any legal or other expenses reasonably incurred by them in connection with investigating or defending any such Claim;
provided, however, that the indemnity agreement contained in this Section 6(b) and the agreement with respect to contribution
contained in Section 7 shall not apply to amounts paid in settlement of any Claim if such settlement is effected without the prior
written consent of the Investor, which consent shall not be unreasonably withheld; provided, further, however, that the Investor
shall be liable under this Section 6(b) for only that amount of a Claim or Indemnified Damages as does not exceed the net proceeds
to the Investor as a result of the sale of Registrable Securities pursuant to such Registration Statement. Such indemnity shall
remain in full force and effect regardless of any investigation made by or on behalf of such Indemnified Party. Notwithstanding
anything to the contrary contained herein, the indemnification agreement contained in this Section 6 with respect to any prospectus
shall not inure to the benefit of any Indemnified Party if the untrue statement or omission of material fact contained in the
prospectus was corrected and such new prospectus was delivered to the Investor prior to the Investor’s use of the prospectus
to which the Claim relates.

 

    	-41-

    	 

    

 

b.Promptly
after receipt by an Indemnified Person or Indemnified Party under this Section 6 of notice of the commencement of any action or
proceeding (including any governmental action or proceeding) involving a Claim, such Indemnified Person or Indemnified Party shall,
if a Claim in respect thereof is to be made against any indemnifying party under this Section 6, 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 Indemnified Person or the Indemnified Party, as the
case may be; provided, however, that an Indemnified Person or Indemnified Party shall have the right to retain its own counsel
with the fees and expenses of not more than one counsel for such Indemnified Person or Indemnified Party to be paid by the indemnifying
party, if, in the reasonable opinion of counsel retained by the indemnifying party, the representation by such counsel of the
Indemnified Person or Indemnified Party and the indemnifying party would be inappropriate due to actual or potential differing
interests between such Indemnified Person or Indemnified Party and any other party represented by such counsel in such proceeding.
The Indemnified Party or Indemnified Person shall cooperate fully with the indemnifying party in connection with any negotiation
or defense of any such action or claim by the indemnifying party and shall furnish to the indemnifying party all information reasonably
available to the Indemnified Party or Indemnified Person that relates to such action or claim. The indemnifying party shall keep
the Indemnified Party or Indemnified Person 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 Indemnified Party or Indemnified Person, consent
to entry of any judgment or enter into any settlement or other compromise which does not include as an unconditional term thereof

to such claim or litigation. Following indemnification as provided for hereunder, the indemnifying party shall be subrogated to
all rights of the Indemnified Party or Indemnified Person 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 Indemnified Person
or Indemnified Party under this Section 6, except to the extent that the indemnifying party is prejudiced in its ability to defend
such action.

 

c.The
indemnification required by this Section 6 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 Damages are incurred.

 

d.The
indemnity agreements contained herein shall be in addition to (i) any cause of action or similar right of the Indemnified Party
or Indemnified Person against the indemnifying party or others, and (ii) any liabilities the indemnifying party may be subject
to pursuant to the law.

 

7.CONTRIBUTION.

 

To
the extent any indemnification by an indemnifying party is prohibited or limited by law, the indemnifying party agrees to make
the maximum contribution with respect to any amounts for which it would otherwise be liable under Section 6 to the fullest extent
permitted by law; provided, however, that: (i) no seller of Registrable Securities guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any seller of Registrable Securities
who was not guilty of fraudulent misrepresentation; and (ii) contribution by any seller of Registrable Securities shall be limited
in amount to the net amount of proceeds received by such seller from the sale of such Registrable Securities.

 

8.REPORTS

b.file
with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange
Act so long as the Company remains subject to such requirements (it being understood that nothing herein shall limit the Company’s
obligations under Section 6 hereof) and the filing of such reports and other documents is required for the applicable provisions
of Rule 144; and

 

c.furnish
to the Investor, so long as the Investor owns Registrable Securities, promptly upon request, (i) a written statement by the Company

Re:QUANTUMSPHERE,

Ladies
and Gentlemen:

 

We
are counsel to QuantumSphere, Inc., a Nevada corporation (the “Company”), and have represented the Company in connection
with that certain private placement (the “Offering”), pursuant to which the Company issued to ____________________________________
(the “Investor”) 10% Subordinated Convertible Promissory Notes convertible into shares of its common stock, $0.001
par value (the “Common Stock”) and detachable warrants to purchase shares of common stock (the “Warrant”).
Pursuant to the Offering, the Company also has entered into a Registration Rights Agreement with the Investors (the “Registration
Rights Agreement”) pursuant to which the Company agreed, among other things, to register the Registrable Securities (as
defined in the Registration Rights Agreement) under the Securities Act of 1933, as amended (the “Securities Act”).
In connection with the Company’s obligations under the Registration Rights Agreement, on ____________ ____, the Company
filed a Registration Statement on Form ________ (File No. 333-_____________) (the “Registration Statement”) with the
Securities and Exchange Commission (the “SEC”) relating to the Registrable Securities which names the Investor as
a selling stockholder thereunder.

 

In
connection with the foregoing, we advise you that a member of the SEC’s staff has advised us by telephone that the SEC has
entered an order declaring the Registration Statement effective under the Securities Act at [ENTER TIME OF EFFECTIVENESS]
on [ENTER DATE OF EFFECTIVENESS] and we have no knowledge, after telephonic inquiry of a member of the SEC’s staff,
that any stop order suspending its effectiveness has been issued or that any proceedings for that purpose are pending before,
or threatened by, the SEC and the Registrable Securities are available for resale under the Securities Act pursuant to the Registration
Statement.

INTERCREDITOR
AND COLLATERAL AGENT AGREEMENT

 

THIS
INTERCREDITOR AND COLLATERAL AGENT AGREEMENT (this “Agreement”), is entered into as of __________________, 2013 by
and among QuantumSphere, Inc., a California corporation (“Borrower”), David Nemelka, Jr., an individual (the
“Collateral Agent”), and each of the secured parties whose name appears on the signature pages to this Agreement
(individually, a “Secured Party” and, collectively, the “Secured Parties”).

 

RECITALS

 

WHEREAS,
each of the Secured Parties has loaned, is loaning or will be loaning monies to Borrower, as evidenced by 10% Secured Convertible
Promissory Notes (collectively, the “Notes”) and as more particularly described in the Note Purchase Agreement
entered into or to be entered into by and between Borrower and each Secured Party; and

 

WHEREAS,
the Notes shall be secured by certain Collateral, as such term is defined in that certain Security Agreement dated of even date
herewith among Borrower and the Secured Parties (the “Security Agreement”); and

 

WHEREAS,
it is the intention of each of the Secured Parties that his, her or its security interests and liens against the Collateral be
of equal priority position, notwithstanding the different dates and times of his, her or its acquisition of the Notes; and

 

WHEREAS,
it is desirable to provide for the orderly administration of the Collateral by requiring each Secured Party to appoint the Collateral
Agent, and the Collateral Agent has agreed to accept such appointment and to receive, hold and deliver the Collateral, all upon
the terms and subject to the conditions hereinafter set forth; and

 

WHEREAS,
it is desirable to allocate the enforcement of certain rights of the Secured Parties under the Notes for the orderly administration
thereof.

 

NOW,
THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are mutually acknowledged, each of the Secured
Parties hereby agree as follows:

 

1.Definitions.
All capitalized terms not otherwise defined herein shall the meanings ascribed to them in the Notes and the Security Agreement.

 

2.Pari
Passu Ranking. Notwithstanding the dates and times of perfection of the security interest issued in favor of each Secured
Party pursuant to the Security Agreement, each Secured Party’s security interest in and lien against the collateral referred
to in Schedule A of the Notes (the “Collateral”) shall rank pari passu, and, accordingly, have the same
and equal priority position.

 

	 	a.	Seniority.
    As of the date hereof, subject to subsection (b) below, the Notes and the Secured Obligations (as defined in the Security
    Agreement) shall be senior to all other obligations of Borrower other than trade debt and other debt incurred in the ordinary
    course of business.
	 	 	 
	 	b.	Subordination.
    The Collateral Agent and the Secured Parties expressly agree to the subordination of the Notes and the Secured Obligations
    (as defined in the Security Agreement) to that certain financing to be secured by Borrower from Novus Capital in the proposed
    amount of Seven Hundred Fifty Dollars ($750,000.00) (the “Novus Capital Financing”), where no further action
    need to be taken by Borrower other than written notice from Borrower as to the funding of the Novus Capital Financing and
    the subordination of the Notes and the Secured Obligations thereby.

 

    	 	 	 

    	 	 	 

    

 

3.Appointment
of the Collateral Agent. The Secured Parties hereby appoint the Collateral Agent (and the Collateral Agent hereby accepts
such appointment) to take any action including, without limitation, the registration of any Collateral in the name of the Collateral
Agent or its nominees prior to or during the continuance of an Event of Default (as defined in the Notes), the exercise of rights
upon the occurrence and during the continuance of an Event of Default, the application of any cash collateral received by the
Collateral Agent to the payment of the Notes, the making of any demand under the Notes or the Security Agreement, the exercise
of any remedies given to the Secured Parties pursuant to the Notes and the exercise of any authority pursuant to the appointment
of the Collateral Agent as an attorney-in-fact pursuant to the Notes that the Collateral Agent deems necessary or proper for the
administration of the Collateral pursuant to the Notes. The Collateral Agent may also exercise in respect of the Collateral, in
addition to other rights and remedies provided for in the Notes and the Security Agreement or otherwise available to it, all the
rights and remedies of a secured party under the California Uniform Commercial Code. Upon disposition of the Collateral in accordance
with the Notes and the Security Agreement, the Collateral Agent shall promptly distribute any cash or Collateral in accordance
with the Notes. Borrower must notify the Collateral Agent in writing of the issuance of Notes to the Secured Parties. The Collateral
Agent will not be required to act hereunder in connection with Notes the issuance of which was not disclosed in writing to the
Collateral Agent nor will the Collateral Agent be required to act on behalf of any assignee of Notes without the written consent
of the Collateral Agent.

 

4.Action
by the Majority in Interest.

 

	 	a.	Certain
    Actions. Each of the Secured Parties covenants and agrees that only a Majority in Interest shall have the right, but not
    the obligation, to undertake the following actions (it being expressly understood that less than a Majority in Interest hereby
    expressly waive the following rights that they may otherwise have under the Notes and the Security Agreement:

 

	 	(i)	Acceleration.
    If an Event of Default occurs, after the applicable cure period, if any, a Majority in Interest may, on behalf of all the
    Secured Parties, instruct the Collateral Agent to provide to Borrower notice to cure such default and/or declare the unpaid
    principal amount of the Notes to be due and payable, together with any and all accrued interest thereon and all costs payable
    pursuant to such Notes;

 

(ii)Enforcement.
Upon the occurrence of any Event of Default after the applicable cure period, if any, a Majority in Interest may instruct the
Collateral Agent to proceed to protect, exercise and enforce, on behalf of all the Secured Parties, their rights and remedies
under the Notes and Security Agreement against Borrower, and such other rights and remedies as are provided by law or equity;

 

(iii)Waiver
of Past Defaults. A Majority in Interest may instruct the Collateral Agent to waive any Event of Default by written notice
to Borrower, and the other Secured Parties, but not waive damages accrued or accruing until the effective date of such waiver.

 

    	 	 	 

    	 	 	 

    

 

	 	b.	Permitted
    Subordination and Release. A Majority in Interest may instruct the Collateral Agent to agree to release in whole or in
    part or to subordinate any Collateral to any claim or other actual or proposed security interest and may enter into any agreement
    with Borrower to evidence such subordination; provided, however, that subsequent to any such release or subordination,
    each Note shall remain pari passu with the other Notes held by the Secured Parties.
	 	 	 
	 	c.	Further
    Actions. A Majority in Interest may instruct the Collateral Agent to take any action that it may take under this Agreement
    by instructing the Collateral Agent in writing to take such action on behalf of all the Secured Parties.
	 	 	 
	 	d.	Majority

    percent (50.1%) of the outstanding principal amount of the Notes, excluding any principal amount of Notes held beneficially
    or of record by Borrower.
	 	 	 
	 	e.	Effect
    of Instruction. The Collateral Agent shall be bound by, and subject to, any limitation or restrictions on the exercise of
    its rights, powers or discretion set forth in any instruction it receives from a Majority in Interest (it being understood
    that a Majority in Interest shall, upon consultation with the Collateral Agent, have the right to direct and control the election,
    exercise and enforcement of the Secured Parties’ rights and remedies under the Notes and the Security Agreement against
    Borrower (including without limitation the commencement, conduct or settlement of any litigation, foreclosure or other action
    or proceeding, and the voting of any securities) without unduly restricting the Collateral Agent’s ability to conduct
    the orderly marketing and sale of any assets or securities of Borrower that may be subject to sale upon foreclosure, settlement
    or otherwise.

 

5.Power
of Attorney.

 

	 	a.	To
    effectuate the terms and provisions hereof, the Secured Parties hereby appoint the Collateral Agent as their attorney-in-fact
    (and the Collateral Agent hereby accepts such appointment) for the purpose of carrying out the provisions of this Agreement
    including, without limitation, taking any action on behalf of, or at the instruction of, the Majority in Interest at the written
    direction of the Majority in Interest and executing any consent authorized pursuant to this Agreement and taking any action
    and executing any instrument that the Collateral Agent may deem necessary or advisable (and lawful) to accomplish the purposes
    hereof.
	 	 	 
	 	b.	All
    acts done under the foregoing authorization are hereby ratified and approved and neither the Collateral Agent nor any designee
    nor agent thereof shall be liable for any acts of commission or omission, for any error of judgment, for any mistake of fact
    or law except for acts of gross negligence or willful misconduct.
	 	 	 
	 	c.	This
    power of attorney, being coupled with an interest, is irrevocable while this Agreement remains in effect.

 

6.Reliance
on Documents and Experts. The Collateral Agent shall be entitled to rely upon any notice, consent, certificate, affidavit,
statement, paper, document, writing or communication (which may be by telegram, cable, telex, telecopier, or telephone) reasonably
believed by it to be genuine and to have been signed, sent or made by the proper person or persons, and upon opinions and advice
of its own legal counsel, independent public accountants and other experts selected by the Collateral Agent.

 

    	 	 	 

    	 	 	 

    

 

7.Actions.

 

	 	a.	The
    Secured Parties agree (which agreement shall survive any termination of this Agreement) to indemnify the Collateral Agent,
    from and against any and all liabilities, obligations, losses, damages, claims, penalties, actions, judgments, suits, costs,
    expenses or disbursements of any kind or nature whatsoever which may at any time be imposed on, incurred by, or asserted against
    the Collateral Agent in any way relating to or arising out of this Agreement, the Notes and any other agreement relating thereto,
    including the reimbursement of the Collateral Agent for all reasonable out-of-pocket expenses (including attorneys’
    fees and expenses) incurred by the Collateral Agent hereunder or in connection herewith or in enforcing the obligations of
    Borrower under this Agreement and the Notes, in all cases as to which the Collateral Agent is not reimbursed by Borrower;
    provided, that none of the Secured Parties, expressly excluding the Collateral Agent, shall be liable for the payment of any
    portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements
    determined by a court of competent jurisdiction in a final proceeding to have resulted solely from the Collateral Agent’s
    gross negligence or willful misconduct. The Collateral Agent shall not be required to take or omit to take any action hereunder
    or under the Notes, or to prosecute or defend any suit in respect of this Agreement or any of the Notes, or any other agreement
    relating thereto, unless indemnified to its satisfaction by the Secured Parties against loss, costs, liability, and expense.
    The Collateral Agent may delegate its duties hereunder to affiliates, agents, attorneys-in-fact and receivers (which term
    includes receivers as managers) selected in good faith by the Collateral Agent.
	 	 	 
	 	b.	Exculpation.

 

	 	(i)	The
    Collateral Agent shall have no duties or responsibilities except those expressly set forth in this Agreement, and the Collateral
    Agent shall not by reason of this Agreement or any of the Notes (or otherwise) be a trustee for any Secured Party or have
    any fiduciary obligation to any Secured Party or any of their affiliates. Neither the Collateral Agent nor any of its directors,
    partners, members, managers, officers, employees or agents (collectively, the “Related Parties”) shall be liable
    to any Secured Party for any action taken or omitted to be taken by it under this Agreement and the Notes, or in any agreements
    delivered in connection therewith, or in connection herewith or therewith, except for its own willful misconduct or gross
    negligence, nor shall the Collateral Agent or any Related Parties be responsible for any recitals or representations or warranties
    herein or therein or in any other agreement delivered in connection therewith, or for the effectiveness, enforceability, validity
    or due execution of any of this Agreement, the Notes or in any other agreement delivered in connection therewith, nor for
    the creation, perfection or priority of any security interests purported to be created under any of the Notes or the validity,
    genuineness, enforceability, existence, value or sufficiency of any Collateral, nor shall the Collateral Agent or any Related
    Parties be obligated to make any inquiry respecting the performance by Borrower of its obligations hereunder or thereunder
    or in any other agreement delivered in connection therewith. Any such inquiry by the Collateral Agent shall not obligate it
    to make any further inquiry or to take any action. The Collateral Agent shall be entitled to rely upon advice of counsel concerning
    legal matters and upon any notice, consent, certificate, statement, or writing which they believe to be genuine and to have
    been presented by a proper Person. The Collateral Agent shall not be responsible for the negligence or misconduct of any such
    agents or attorneys-in-fact selected by it with reasonable care.

 

    	 	 	 

    	 	 	 

    

 

(ii)The
Collateral Agent shall be entitled to rely upon any certification, notice or other communication (including any thereof by email,
telex, telecopy, telegram or cable) reasonably believed by it to be genuine and correct and to have been signed or sent by or
on behalf of the proper person or persons, and upon advice and statements of legal counsel (including counsel to Borrower), independent
accountants and other experts selected by the Collateral Agent with reasonable care. As to any matters not expressly provided
for by this Agreement, the Collateral Agent shall in all cases be fully protected in acting, or in refraining from acting, hereunder
in accordance with instructions signed by all Secured Parties, in its capacity as agent of the Secured Parties, and any action
taken or failure to act pursuant thereto, shall be binding on all of the Secured Parties.

 

iii)The
Collateral Agent shall not be required to take any action that is in its opinion contrary to law or to the terms of this Agreement
and the Notes, or which would in its opinion subject it or any of its Related Parties to liability. The Collateral Agent shall,
in all cases, be fully justified in failing or refusing to act hereunder and under the Notes unless it shall be fully indemnified
to its satisfaction against any and all liability and expense which may be incurred by it by reason of taking or continuing to
take any such action.

 

(iv)The
Collateral Agent may deem and treat the payee of any promissory note or other evidence of indebtedness relating to the Notes as
the owner thereof for all purposes hereof unless and until a written notice of the assignment or transfer thereof, signed by such
payee and in form reasonably satisfactory to the Collateral Agent, shall have been filed with the Collateral Agent. Any request,
authority or consent of any Person who at the time of making such request or giving such authority or consent is the holder of
any such note or other evidence of indebtedness shall be conclusive and binding on any subsequent holder, transferee or assignee
of such note or other evidence of indebtedness and of any note or notes or other evidences of indebtedness issued in exchange
therefor.

 

    	 	 	 

    	 	 	 

    

 

	 	c.	Successor.
    The Collateral Agent may resign at any time upon at least 30 days’ notice to the Secured Parties. If the Collateral
    Agent at any time shall resign, the Secured Parties, by majority consent, may appoint another mutually agreed Secured Party
    as a successor to the Collateral Agent. If the Secured Parties do not make such appointment within ten (10) business days
    prior to the scheduled resignation date of the Collateral Agent, the retiring Collateral Agent shall appoint a new Collateral
    Agent from the Secured Parties or, if no Secured Party accepts such appointment, from among commercial banking institutions
    or trust institutions generally. In furtherance of the foregoing, upon the announcement that the Collateral Agent will resign
    in its capacity as the Collateral Agent, each of the Secured Parties agrees to use its best efforts to promptly appoint another
    Collateral Agent. Upon the acceptance of any appointment as the Collateral Agent hereunder, such successor Collateral Agent
    shall be entitled to receive from the retiring Collateral Agent such documents of transfer and assignment as such successor
    Collateral Agent may reasonably request, and shall thereupon succeed to and become vested with all rights, powers, privileges
    and duties of the retiring Collateral Agent, and the retiring Collateral Agent shall be discharged from its duties and obligations
    under this Agreement and the Notes. After the retiring Collateral Agent’s resignation hereunder as the Collateral Agent,
    the provisions of this Section 3 shall inure to its benefit as to any actions taken or omitted to be taken by it while it
    was the Collateral Agent under this Agreement and the Notes, and any other agreement relating thereto.

 

8.Application
of Proceeds.

 

	 	a.	Any
    and all amounts actually received by the Collateral Agent in connection with the enforcement of the Notes, shall, promptly
    upon receipt by the Collateral Agent, be applied:

 

	 	(i)	First,
    to the payment in full of all amounts owing to the Collateral Agent in respect of any fees and expenses (including attorneys’
    fees and expenses and fees and expenses of its agents) incurred by or on behalf of the Collateral Agent as a result of administering
    this Agreement or the Collateral or exercising any rights (including foreclosure of the Collateral) in its capacity as Collateral
    Agent;

 

(ii)Second,
following payment of all obligations under clause (i), between and among each of the Secured Parties on a pro rata basis, computed
using the then outstanding indebtedness, of both principal and accrued interest, of Borrower to each of the Secured Parties, as
of the date of such distribution. Until the proceeds are so distributed, the Collateral Agent shall hold the proceeds in trust
for the benefit of each of the Secured Parties; and

 

(iii)Third,
to Borrower unless otherwise directed by a court of competent jurisdiction.

 

    	 	 	 

    	 	 	 

    

 

	 	b.	The
    priorities of allocation set forth in Section 4(a) above shall apply in all circumstances, including with respect to any distribution
    made in any case or proceeding under any bankruptcy law or insolvency law involving creditors’ rights generally.
	 	 	 
	 	c.	If
    any Secured Party (an “Excess Party”) shall obtain any payment or other recovery (whether voluntary, involuntary,
    by application of setoff, or otherwise) as a result of the realization, sale or other remedial disposition of, or foreclosure
    on, any Collateral in excess of the amount it is then entitled to receive under the terms of this Agreement, such Excess Party
    shall hold such amount in trust for the ratable benefit of the other Secured Parties in accordance with the terms of this
    Agreement and shall pay an amount equal to such excess to the Collateral Agent for distribution to the Secured Parties in
    accordance with the terms of this Agreement.

 

9.Ambiguity;

	 	a.	In
    the event of any ambiguity or uncertainty hereunder or in any notice, certificate, instruction or other communication received
    by the Collateral Agent hereunder, the Collateral Agent may, in its sole discretion, refrain from taking any action other
    than retain possession of the Collateral, unless the Collateral Agent receives written instructions, signed by the Majority
    in Interest, or an opinion of counsel of Borrower reasonably satisfactory to it, which eliminates such ambiguity or uncertainty.
	 	 	 
	 	b.	In
    the event of any dispute between or conflicting claims by or among Borrower, the Secured Parties and/or the Collateral Agent
    and/or any other person or entity with respect to any Collateral, the Collateral Agent shall be entitled, in its sole discretion,
    to refuse to comply with any and all claims, demands or instructions with respect to such Collateral so long as such dispute
    or conflict shall continue, and Collateral Agent shall not be or become liable in any way to Borrower or the Secured Parties
    for failure or refusal to comply with such conflicting claims, demands or instructions. The Collateral Agent shall be entitled
    to refuse to act until, in its sole discretion, such conflicting or adverse claims or demands shall have been determined by
    a final order, judgment or decree of a court of competent jurisdiction, which order, judgment or decree is not subject to
    appeal, or settled by agreement between the conflicting parties as evidenced in a writing satisfactory to Collateral Agent.
    The Collateral Agent may, in addition, elect, in its sole discretion, to commence an interpleader action or seek other judicial
    relief or orders as it may deem, in its sole discretion, necessary. The costs and expenses (including reasonable attorneys’
