UNIT
SUBSCRIPTION AGREEMENT

 

The
undersigned, [__________________________] (“Subscriber”), hereby agrees with Quantum Materials Corp., a Nevada
corporation (“Company”), as follows:

 

1.Reference
is made to that certain Private Placement Memorandum of the Company, dated March 2016, pursuant to which the Company is offering
for sale (the “Offering”) 3,000 units of the Company (each, a “Unit”), each consisting of
(a) a $1,000 Unsecured Convertible Promissory Note (the “Note,” and together with each other Note issued pursuant
to the Offering, the “Notes”) and (b) a warrant (the “Warrant,” and together with each other
Warrant issued pursuant to the Offering, the “Warrants”) to purchase 4,166 shares of the Common Stock, par
value $0.001 per share, of the Company (“Common Stock”) at a purchase price of $0.15 per share.

 

2.Subscriber
hereby subscribes for [___________] Units, and in consideration thereof, Subscriber hereby pays the Company an aggregate amount
of $[__________]. The minimum subscription is 50 Units unless waived by the Company. 

 

3.Subscriber
acknowledges, represents and warrants to the Company as follows:

 

(a)Subscriber
understands that the Units have not been registered under the Securities Act of 1933, as amended from time to time (the “Federal
Act”), or any state securities laws, by reason of specific exemptions under the provisions thereof which depend in part
upon the representations made by Subscriber in this Agreement. Subscriber understands that the Company is relying upon Subscriber’s
representations and agreements contained in this Agreement (and any supplemental information furnished by Subscriber) for the
purpose of determining whether this transaction meets the requirements for such exemptions.

 

(b)Subscriber
has such knowledge, skill and experience in business, financial and investment matters so that Subscriber is capable of evaluating
the merits and risks of an investment in the Units. Subscriber is an “accredited investor” within the meaning of Rule
501 of Regulation D of the Federal Act and is a sophisticated investor with knowledge and experience in business and financial
matters. To the extent that Subscriber has deemed it appropriate to do so, Subscriber has retained, and relied upon, appropriate
professional advice regarding the tax, legal and financial merits and consequences of the investment in the Units.

 

(c)Subscriber
understands that the Units are “restricted securities” under applicable Federal securities laws and that the Federal
Act and the rules of the Securities and Exchange Commission provide in substance that Subscriber may dispose of the Units only
pursuant to an effective registration statement under the Federal Act or an exemption from such registration if available. Subscriber
further understands that the Company has no obligation or intention to register any of the Units under or to take action so as
to permit sales pursuant to the Federal Act. Accordingly, Subscriber may dispose of the Units only in certain transactions which
are exempt from registration under the Federal Act, including “private placements,” in which event the transferee
will acquire “restricted securities” subject to the same limitations as in the hands of the Subscriber. Subscriber
further understands that state securities laws allow sales of the Units only if the Units are registered or the transaction is
subject to an applicable exemption. As a consequence, Subscriber understands that Subscriber must bear the economic risks of the
investment in the Units for an indefinite period of time.

 

    	 	 	 

     

    

 

(d)Subscriber
hereby confirms that Subscriber is acquiring the Units for investment only and not with a view to or in connection with any resale
or distribution of the Units. Subscriber hereby affirms that Subscriber has no present intention of making any sale, assignment,
pledge, gift, transfer or other disposition of the Units or any interest therein.

 

(e)Subscriber
has not directly or indirectly, nor has any person acting on behalf of or pursuant to any understanding with such Subscriber,
engaged in any transactions in the securities of the Company (including, without limitations, any Short Sales involving the Company’s
securities) since the earlier to occur of (i) the time that Subscriber was first contacted by the Company, Roth Capital Partners,
LLC, or any other person regarding an investment in the Company and (ii) the thirtieth (30th) day prior to the date of this Agreement.
Subscriber covenants that neither it nor any person acting on its behalf or pursuant to any understanding with it will engage
in any transactions in the securities of the Company (including Short Sales) prior to the time that the transactions contemplated
by this Agreement are publicly disclosed. For purposes hereof, “Short Sales” include, without limitation, all “short
sales” as defined in Rule 200 promulgated under Regulation SHO under the Securities Exchange Act of 1934, as amended, and
all types of direct and indirect stock pledges, forward sale contracts, options, puts, calls, short sales, swaps and similar arrangements
(including on a total return basis), and sales and other transactions through non-US broker dealers or foreign regulated brokers.

 

4.Subscriber
acknowledges and agrees that the Company does not currently have adequate shares of Common Stock in its treasury to permit the
conversion of the Notes or the Warrants comprising the Units. As such, the Subscriber acknowledges and agrees that the Company
will undertake to amend its certificate of incorporation, which action will require approval of the Company’s stockholders,
and will use commercially reasonable efforts to amend its certificate of incorporation; provided however, that there can be no
assurance that the Company will be successful in its efforts to obtain shareholder approval for the amendment to the Company’s
certificate of incorporation to increase the authorized number of shares of Common Stock, such that there will be an adequate
number of shares of Common Stock to permit the conversion of the Notes and the exercise of the Warrants. Accordingly, the Subscriber
acknowledges and agrees that it may not be able to convert the Notes or exercise the Warrants in the foreseeable future.

 

5.Subscriber
acknowledges and agrees that the certificate(s) evidencing the shares of Common Stock issued by the Company to Subscriber pursuant
to the terms and conditions of the Units will bear the following legend:

 

The shares represented by this certificate have not been registered under the Securities Act of 1933 or any state securities laws and may not be sold or transferred in the absence of such registration or an exemption therefrom under the Securities Act of 1933 and applicable state securities laws.

 

6.Subscriber
acknowledges that neither the Company nor any person acting on its behalf has offered or sold the Units to Subscriber by any form
of general solicitation, general or public media advertising or mass mailing.

7.With
the written consent of the Company and the record holders of a majority of the principal amount of Notes then outstanding (“Majority
in Interest”), the obligations of the Company and the rights of the holders of the Notes may be waived (either generally
or in a particular instance, either retroactively or prospectively and either for a specified period of time or indefinitely),
and with the same consent, such parties may amend this Agreement and the Notes. Without limiting the generality of the above,
the Company and a Majority in Interest may require a conversion of all Notes into equity, extend the maturity of all Notes, and
amend the applicable conversion rate of all Notes. The affirmative consent of each Noteholder would be required for any amendment
of such Noteholder’s principal amount and interest rate. Upon the effectuation of any waiver, consent, agreement, amendment
or modification set forth above, the Company shall promptly give written notice thereof to the record holders of the Notes who
have not previously consented thereto in writing.

 

8.The
Company covenants and agrees that it may not, without the consent of a Majority in Interest, voting as a single class: (a) amend
the terms of the Notes, except in accordance with Section 7 above; (b) authorize additional sales of Notes; (c) amend the Certificate
of Incorporation or Bylaws of the Company in any manner which would impair or reduce the rights of the holders of the Notes; (d)
liquidate or dissolve the Company; (e) enter into any line of business other than a business substantially similar or related
to the existing business of the Company; or (f) dispose of any material assets of the Company with a total value in excess of
$3 million. 

 

9.The
Notes shall be treated on a parri passu basis. All payments shall be made on a pro rata basis, based upon
the outstanding principal balance of the Notes.

 

10.Subscriber
covenants and agrees to, simultaneously with Subscriber’s execution and delivery of this Agreement, complete and deliver
the Investor Questionnaire set forth on Exhibit A hereto. The Company covenants and agrees to, simultaneously with the
Company’s acceptance of this Agreement, execute and deliver to Subscriber the Note substantially in the form set forth on
Exhibit B. The Company and Subscriber covenant and agree to, simultaneously with their execution and delivery (or acceptance)
of this Agreement, execute and deliver the Warrant substantially in the form set forth on Exhibit C.

PROSPECTIVE
PURCHASER QUESTIONNAIRE

 

Quantum
Materials Corp., a Nevada corporation (the “Company”), is offering shares of Common Stock (the “Securities”)
under the exemption from the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”),
for a private offering of securities pursuant to Rule 506 of Regulation D, as amended, promulgated by the Securities and Exchange
Commission under the Securities Act (“Regulation D”). Regulation D provides certain guidelines for complying
with that exemption. In order to comply with those guidelines, the Company must have reasonable grounds to believe that each prospective
purchaser of the Securities has such knowledge and experience in financial, investment and business matters so as to be capable
of evaluating the merits and risks of the prospective investment and/or is deemed to be an “accredited investor” under
Regulation D. The purpose of this questionnaire (this “Questionnaire”) is to obtain certain information from
each prospective purchaser of Securities in order to enable the Company to satisfy its obligations under the requirements of that
exemption. Prior to the Company issuing the Securities, each prospective purchaser must satisfy the Company with respect to, among
other things, the prospective purchaser’s ability to bear the economic risks of an investment in the Securities.

 

If
the Securities are to be issued in joint names (for example, in the names of both husband and wife), please answer the questions
on behalf of both such prospective purchasers. Separate Questionnaires need not be completed by each such person unless so directed
in response to question number 3 below. If additional space is needed to respond to any particular question, supplemental sheets
should be attached.

 

This
Questionnaire will be reviewed and retained by the Company. The Company will maintain the confidentiality of the information contained
in this Questionnaire, subject to any requirement that the Company establish the availability of the exemption from registration
or compliance with the accreditation standards referred to above or compliance with the applicable provisions of law.

 

In
connection with the private offering of the Securities, the undersigned represents and warrants as follows, upon the accuracy
and completeness of which representations and warranties the Company may rely in determining whether the offering is exempt from
registration and satisfies certain other requirements of applicable federal and state securities laws (questions that do not apply
to particular investors should be left blank):

CERTAIN UNIT SUBSCRIPTION AGREEMENT AMONG QUANTUM MATERIALS CORP., A NEVADA CORPORATION (THE “COMPANY”), AND
THE PERSON IDENTIFIED AT THE END OF THIS INSTRUMENT AS THE INVESTOR (THE “INVESTOR”), DATED AS OF THE DATE
HEREOF, AS THE SAME MAY BE AMENDED FROM TIME TO TIME (THE “UNIT SUBSCRIPTION AGREEMENT”).

 

NEITHER
THE WARRANTS GRANTED HEREIN NOR THE UNDERLYING SECURITIES HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
“SECURITIES ACT”), OR ANY STATE OR OTHER SECURITIES LAW. THE HOLDER HEREOF, BY ACQUIRING THIS INSTRUMENT, AGREES

This

and payment of such Exercise Price to the Company, but subject to the conditions set forth herein. Payment of the Exercise Price
shall be made in immediately available funds and shall be accompanied by the Form of Exercise attached hereto properly completed
by the holder.

 

The
Warrants evidenced hereby shall be exercisable at any time and from time to time for Applicable Securities upon the exercise thereof
in accordance with the terms hereof; provided however, that the Warrants may not be exercised after (and shall expire

the Company transfer greater than 50% of the then issued and outstanding equity securities of Company.

 

    	 	 	 

     

    

 

The
Applicable Securities issued upon the exercise of the Warrants shall be subject to, and have all the benefits of, the rights,
preferences and privileges of such series of securities.

 

Exercise
of Warrants

 

The
holder of Warrants evidenced hereby may exercise them, in part or in whole, by surrendering this instrument, with the Form of
Exercise attached hereto properly completed and executed, and paying the Exercise Price. In the event that upon any exercise of
Warrants evidenced hereby the number of Warrants exercised shall be less than the total number of Warrants evidenced hereby, there
shall be issued to the holder hereof a new instrument evidencing the number of Warrants not exercised. No adjustment to the Exercise
Price will be made for any declared and unpaid dividends or distributions on any Applicable Securities issuable upon exercise
of Warrants evidenced hereby.

 

The
Company shall, to the extent necessary, issue fractional Applicable Securities upon exercise of Warrants or pay the cash equivalent
thereof, at the Company’s option.

 

Taxes
upon Exercise

Company shall pay any documentary, stamp or similar issue or transfer tax due on the issue of the Applicable Securities upon exercise

number of Warrants evidenced hereby.

 

The
certificates for Applicable Securities issued upon exercise, if any, may have notations, legends or endorsements required by law,
stock exchange rule, agreements to which the Company is subject or as the Company may deem necessary or desirable. By acceptance
of a certificate representing any Applicable Securities issued upon exercise of Warrants, the holder hereof acknowledges any restrictions
on transfer set forth on such certificate and agrees that such holder will transfer such Applicable Securities only as provided
thereon.

 

    	 	 	 

     

    

 

All
Applicable Securities delivered upon exercise of Warrants shall be newly issued, duly authorized, validly issued, fully paid and
non-assessable and free from any lien or adverse claim. The Company will endeavor promptly to comply with all federal and state
securities laws regulating the offer and delivery of Applicable Securities upon exercise of Warrants, if any.

 

(a)Adjustments
for Subdivisions, Combinations or Consolidations.

 

(i)Subdivisions.
In the event that the Company shall effect a subdivision of outstanding Applicable Securities, the number of Applicable Securities
issuable upon exercise of this Warrant immediately prior to such subdivision shall be proportionately increased, and the Exercise
Price in effect immediately prior to such subdivision shall concurrently with such subdivision be proportionately decreased.

 

(ii)Combinations
or Consolidations. In the event that the outstanding Applicable Securities shall be combined or consolidated, by reclassification
or otherwise, into a lesser number of Applicable Securities, the number of Applicable Securities issuable upon exercise of this
Warrant immediately prior to such combination or consolidation shall be proportionately decreased, and the Exercise Price in effect
immediately prior to such combination or consolidation shall, concurrently with the effectiveness of such combination or consolidation,
be proportionately increased.

 

(b)Adjustment
for Reclassification, Exchange or Substitution. If the Applicable Securities shall be changed into the same or a different
number of securities in any class or classes of securities, whether by capital reorganization, reclassification or otherwise (other
than a reorganization, merger, consolidation, or sale of assets provided for below), then and in each such event the holder of
each Warrant shall have the right thereafter to exercise such Warrant for the kind and amount of securities and other securities
and property receivable upon such reorganization, reclassification, or other change, by holders of the number of Applicable Securities
for which such Warrants might have been exercised immediately prior to such reorganization, reclassification or change, all subject
to further adjustment as provided herein.

 

(c)Adjustment
for Merger or Reorganization, etc. In case of any consolidation or merger of the Company with or into a corporation or another
entity or the conversion of the Company into a corporation by any other means, each Warrant shall thereafter be exercisable for
the kind and amount of equity interests or other securities or property to which a holder of the number of Applicable Securities
of the Company deliverable upon exercise of such Warrant would have been entitled upon such consolidation, merger or sale; and,
in such case, appropriate adjustment (as determined in good faith by the Board of Directors of the Company) shall be made in the
application of the provisions in this Paragraph (c) set forth with respect to the rights and interest thereafter of the holders
of the Warrants, to the end that the provisions set forth in this Section (including provisions with respect to changes in and
other adjustments of the number of Warrants evidenced hereby or the Exercise Price therefor) shall thereafter be applicable, as
nearly as reasonably may be, in relation to any equity interests or other property thereafter deliverable upon the exercise of
the Warrants.

 

    	 	 	 

     

    

 

(d)Certificate
as to Adjustments. Upon the occurrence of each adjustment or readjustment pursuant to paragraphs (a) - (d) hereof, the Company
at its expense shall promptly compute such adjustment or readjustment in accordance with the terms hereof and furnish to each
holder of a Warrant or Warrants a certificate setting forth such adjustment or readjustment and showing in detail the facts upon
which such adjustment or readjustment is based. The Company shall, upon the written request at any time of any holder of a Warrant,
furnish or cause to be furnished to such holder a similar certificate setting forth (i) such adjustments and readjustments, (ii)
the Exercise Price then in effect, and (iii) the number of Applicable Securities and the amount, if any, of other property which
then would be received upon the exercise of such Warrant.

 

Notice
of Certain Transactions

 

In
the event that (a) the Company takes any action which would require an adjustment in the Exercise Price, (b) the Company agrees
to undertake any transaction regarding an adjustment hereunder, or (c) there is a dissolution of liquidation of the Company, then
in each case, the Company shall mail to the holder a notice stating the proposed record or effective date, as the case may be.
The Company shall mail the notice at least five days before the earlier of the proposed record date or the proposed effective
date.

 

Transferability

 

This
instrument and the Warrants may not be transferred without the prior written consent of the Company, which may be granted or withheld
in the sole and absolute discretion of the Company. Without limiting the generality of the above, the Warrants evidenced hereby
are transferable only if either (x) they first shall have been registered under the Securities Act, or (y) the Company first shall
have been furnished with an opinion of legal counsel, reasonably satisfactory to the Company, to the effect that such sale or
transfer is exempt from the registration requirements of the Securities Act. Any permitted Transfer shall be effected upon surrender
of this instrument to the Company for such purpose, together with a written assignment on the Form of Assignment attached hereto,
or in other form satisfactory to the Company, duly executed by the holder hereof, together with funds to pay any transfer, documentary,
stamp or other taxes or government charges payable in connection with such transfer and any other amounts required pursuant to
this instrument. Upon the surrender of this instrument and payment as aforesaid, the Company will deliver a new instrument, in
the name of the assignee and evidencing Warrants in a permissible denomination or denominations specified in such instrument of
assignment. If less than all of the Warrants evidenced by this instrument are being transferred, the Company will deliver a new
instrument for the portion of the Warrants not being transferred.

 

No
Shareholder Rights

 

Nothing
contained in this instrument shall be construed as conferring upon the Investor or any other person the right to vote or to consent
or to receive notice as a shareholder in respect of meetings of shareholders for the election of members of the Board of Directors
of the Company or any other matters or any rights whatsoever as a shareholder of the Company; and no distributions shall be payable
or accrued in respect of this instrument or the interest represented hereby or the securities obtainable hereunder until, and
only to the extent that, the Warrants shall have been exercised.

and a Warrants Majority in Interest. “Warrants Majority in Interest” means the holders of warrants that were
issued pursuant to the Unit Subscription Agreement and the Offering contemplated thereunder (including the Warrants hereunder),
representing more than 50% of the equity interests that may be acquired thereunder.

 

Governing
Law; Consent to Jurisdiction

 

THIS
INSTRUMENT WILL BE INTERPRETED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE State of Texas.
