AND CONSENT AGREEMENT


 


THIS

by and between QUANTUM MATERIALS, INC., a Nevada corporation (the “Company”), and LINCOLN PARK CAPITAL
FUND, LLC, an Illinois limited liability company (the “Investor”).


 


WHEREAS,
the Investor and Company entered into a Securities Purchase Agreement, dated as of November 7, 2016 (the “LPC Securities
Purchase Agreement”) and, pursuant thereto, the Company issued and sold to the Investor a Non-Negotiable Unsecured Convertible
Promissory Note (the “LPC Note”) (Capitalized terms used herein and not otherwise defined herein shall have the meanings
ascribed to them in the LPC Securities Purchase Agreement or the LPC Note, as applicable); and


 


WHEREAS,
the Company subsequently entered into certain transactions referred to herein as the “Subject Transaction:” (i)
an Equity Purchase Agreement, dated as of March 29, 2017 (the “Equity Purchase Agreement”), by and between the Company
and L2 Capital, LLC, a Kansas limited liability company (“L2”), and SBI Investments LLC, 2014-1, a statutory series
of Delaware limited liability company (“SBI”), (ii) promissory notes dated March 29, 2017 issued to L2 and SBI in
connection with the transactions contemplated by the Equity Purchase Agreement (collectively, the “EPA Notes”), (iii)
each of those certain Securities Purchase Agreements, dated as of March 29, 2017 (collectively, the “Securities Purchase
Agreements”), by and between the Company and each of L2 and SBI, and (iv) each of the promissory notes dated March 29, 2017
issued to L2 and SBI in connection with the transactions contemplated by the Securities Purchase Agreements (collectively, the
“SPA Notes”); and


 


WHEREAS,
the Company desires to obtain the Investor’s waiver and consent with respect to the Subject Transaction and the Investor
desires to grant such waiver and consent.


 


NOW
THEREFORE, IN CONSIDERATION of the mutual covenants contained in this Agreement, and for other good and valuable consideration,
the receipt and adequacy of which are hereby acknowledged, the Company and the Investor agree as follows:


 


1.
CONSENT TO EQUITY PURCHASE AGREEMENT 


 


(a)
The Investor agrees to waive the application of Section 17 of the LPC Securities Purchase Agreement solely with respect to the
Subject Transaction and hereby consents to the consummation of the Subject Transaction by the Company as dieclosed in the SEC
filing of April 4, 2017 on form 8-k; provided, however, that such waiver and consent shall apply only to the Subject
Transaction, and the Company and LPC hereby acknowledge and agree that such waiver and consent shall not be deemed to waive the
application of Section 17 of the LPC Securities Purchase Agreement or to consent to any other issuance of Common Stock or Common
Stock Equivalents or any other securities by the Company to the investors of the Subject Transaction or to any other Person in
any other transaction or series of transactions.


 


(b)
Except as otherwise expressly provided herein with respect to the Subject Transaction only, the LPC Securities Purchase Agreement
and the LPC Note each shall continue to be in full force and effect and each is hereby ratified and confirmed in all respects,
including, without limitation Section 17 of the LPC Securities Purchase Agreement.


 




    	 	 	 



     


    

 


(c)
In consideration for this waiver and consent, the Company shall issue to the Investor 1,000,000 shares of Common Stock on the
date hereof (“Consent Shares”).


 


	 	●	Legends.
    The Consent Shares may only be disposed of in compliance with state and federal securities laws. In connection with any transfer
    of Consent Shares other than pursuant to an effective registration statement or Rule 144 (as defined below), to the Company
    or to an affiliate of the Investor, the Company may require the transferor thereof to provide to the Company an opinion of
    counsel selected by the transferor and reasonably acceptable to the Company, the form and substance of which opinion shall
    be reasonably satisfactory to the Company, to the effect that such transfer does not require registration of such transferred
    securities under the 1933 Act. The Investor understands that the Consent Shares, except as set forth below, shall bear any
    legends as required by applicable state securities or “Blue Sky” laws in addition to a restrictive legend in substantially
    the following form (and a stop-transfer order may be placed against transfer of such stock certificates): 
	 	 	 
	 	 	THE
    ISSUANCE AND SALE OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
    AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED
    (I) IN THE ABSENCE OF (A) AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OF 1933, AS AMENDED,
    OR (B) AN OPINION OF COUNSEL TO THE HOLDER (IF REQUESTED BY THE COMPANY), IN A FORM REASONABLY ACCEPTABLE TO THE COMPANY,
    THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT OR (II) UNLESS SOLD OR ELIGIBLE TO BE SOLD PURSUANT TO RULE 144 OR RULE 144A
    UNDER SAID ACT. NOTWITHSTANDING THE FOREGOING, THE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT
    OR OTHER LOAN OR FINANCING ARRANGEMENT SECURED BY THE SECURITIES.


 




    	 	 	 



     


    

 


	 	 	The
    Company shall use its reasonable best efforts to cause its transfer agent to remove the legend set forth above and to issue
    a certificate without such legend to the holder of the Consent Shares upon which it is stamped, or to issue to such holder
    by electronic delivery at the applicable balance account at the Depository Trust Company (“DTC”), unless otherwise
    required by state securities or “blue sky” laws, at such time as (i) such Consent Shares are registered for resale
    under the 1933 Act, (ii) in connection with a sale, assignment or other transfer, such holder provides the Company with an
    opinion of counsel, in a form generally acceptable to the Company’s legal counsel, to the effect that such sale, assignment
    or transfer of the securities may be made without registration under the 1933 Act, or (iii) such holder provides the Company
    and its legal counsel with reasonable assurance in writing that the Consent Shares can be sold, assigned or transferred pursuant
    to Rule 144 or Rule 144A. In furtherance of the foregoing, the Company agrees that, following the effective date of a registration
    statement covering the resale of such Consent Shares or at such time as such legend is not required pursuant to this Section,
    the Company shall, no later than three Trading Days following the delivery by the Investor to the Company or the Company’s
    transfer agent of a certificate representing the Consent Shares issued with a restrictive legend (such third Trading Day,
    the “Legend Removal Date”), either: (A) issue and deliver (or cause to be issued and delivered) to the Investor
    a certificate representing such Consent Shares that is free from all restrictive and other legends or (B) cause the Company’s
    transfer agent to credit the Investor’s or its designee’s account at DTC through its Deposit/Withdrawal at Custodian
    (DWAC) system with a number of Common Shares equal to the number of Consent Shares represented by the certificate so delivered
    by the Investor. If the Company fails on or prior to the Legend Removal Date to either (i) issue and deliver (or cause to
    be issued and delivered) to the Investor a certificate representing the Consent Shares that is free from all restrictive and
    other legends or (ii) cause the Company’s transfer agent to credit the balance account of the Investor or its designee
    at DTC through its Deposit/Withdrawal at Custodian (DWAC) system with a number of Common Shares equal to the number of Consent
    Shares, represented by the certificate delivered by the Investor pursuant hereto, then, in addition to all other remedies
    available to the Investor, the Company shall pay in cash to the Investor on each day after the Legend Removal Date that the
    issuance or credit of such shares is not timely effected an amount equal to 1.0% of the product of (A) the sum of the number
    of Consent Shares not issued to the Investor on a timely basis and to which the Investor is entitled and (B) the VWAP for
    the five Trading Day period immediately preceding the Legend Removal Date. In addition to the foregoing, if the Company fails
    to so properly deliver such unlegended certificates or so properly credit the account of the Investor or its designee at DTC
    by the Legend Removal Date, and if on or after the Legend Removal Date the Investor purchases (in an open market transaction
    or otherwise) Common Stock to deliver in satisfaction of a sale by the Investor of Consent Shares that the Investor anticipated
    receiving from the Company without any restrictive legend, then the Company shall, within three Trading Days after the Investor’s
    request, pay cash to the Investor in an amount equal to the Investor’s total purchase price (including brokerage commissions,
    if any) for the Common Stock so purchased, at which point the Company’s obligation to deliver a certificate or credit
    the Investor’s or its designee’s account at DTC for such Consent Shares shall terminate and such shares shall
    be cancelled.


 




    	 	 	 



     


    

 


 


	 	●	Rule
    144 Availability; Public Information. Commencing May 31, 2017, at all times during the period commencing on the Effective
    Date and ending at such time that all of the Consent Shares can be sold without the requirement to be in compliance with Rule
    144(c)(1) under the 1933 Act and otherwise without restriction or limitation pursuant to Rule 144 under the 1933 Act, the
    Company shall use its reasonable best efforts to ensure the availability of Rule 144 under the 1933 Act to the Investor with
    regard to the Consent Shares including compliance with Rule 144(c)(1) under the 1933 Act. If, (i) at any time the Investor
    owns any Consent Shares, the Company shall fail for any reason to satisfy the current public information requirement under
    Rule 144(c) under the 1933 Act (a “Public Information Failure”), or (ii) the Company shall fail to take such action
    as is reasonably requested by the Investor to enable the Investor to sell the Consent Shares pursuant to Rule 144 under the
    1933 Act (including, without limitation, delivering all such legal opinions, consents, certificates, resolutions and instructions
    to the Company’s transfer agent as may be reasonably requested from time to time by the Investor and otherwise fully
    cooperate with Investor and Investor’s broker to effect such sale of securities pursuant to Rule 144 under the 1933
    Act), then, in either case, in addition to the Investor’s other available remedies, the Company shall pay to a Investor,
    in cash, as liquidated damages and not as a penalty, by reason of any such delay in or reduction of its ability to sell the
    Consent Shares, an amount in cash equal to one percent (1.0%) of the aggregate value of the Investor’s Consent Shares
    on the day of a Public Information Failure and on every thirtieth (30th) day (prorated for periods totaling less than thirty
    days) thereafter until the earlier of (a) the date such Public Information Failure is cured and (b) such time that such public
    information is no longer required for the Investor to transfer the Consent Shares pursuant to Rule 144 under the 1933 Act.
    The payments to which the Investor shall be entitled pursuant to this Section are referred to herein as “Rule 144 Failure
    Payments.” Rule 144 Failure Payments shall be paid on the earlier of (i) the last day of the calendar month during which
    such Rule 144 Failure Payments are incurred and (ii) the third (3rd) Trading Day after the event or failure giving rise to
    the Rule 144 Failure Payments is cured.
	 	 	 
	 	●	Valid
    Issuance of the Consent Shares; The Consent Shares are duly authorized and, when issued in accordance with this Agreement,
    will be validly issued, fully-paid and non-assessable, and free and clear of all Liens imposed by the Company other than restrictions
    on transfer under this Agreement and under applicable state and federal securities laws. The issuance of the Consent Shares
    to the Investor pursuant to this Agreement is exempt from registration under the 1933 Act.
