after October 31, 2016, Borrower shall have raised a cumulative amount of equity capital that exceeds $15,000,000 but is $25,000,000
or less, Borrower shall prepay an amount equal to 30% of the amount raised over $15,000,000 and under $25,000,000 (not to exceed
the balance of principal and interest outstanding on this Note); and

 

(ii)         If
after October 31, 2016, Borrower shall have raised a cumulative amount of equity capital that exceeds $25,000,000, Borrower shall
prepay an amount equal to 50% of the amount over $25,000,000 (not to exceed the balance of principal and interest outstanding on
this Note).

 

Borrower shall make any such
mandatory prepayments on a monthly basis pro-rata as funds are raised over the applicable threshold. Notwithstanding the foregoing,
Borrower may request Lender’s consent upon at least 10 days' notice prior to the date of the capital raise to defer all or
any part of such mandatory prepayment with Lender's written approval; provided, however, that if Borrower elects to defer any such
prepayment, the Fixed Rate shall immediately increase to 8% for the remainder of the term of the Note. Any remaining amounts due
will be payable in a balloon payment at Maturity. Any amounts that are prepaid may not be re-borrowed.

  

5.           Interest
Rates. Until Maturity, the unpaid principal of this Note shall bear interest at the Fixed Rate; provided, however, that
during the continuance of an Event of Default (regardless of any subsequent cure), such principal balance shall bear interest at
the Overdue Rate. After Maturity, such principal balance shall bear interest at the Overdue Rate.

 

6.           Method

or become due and payable (whether at scheduled Maturity or by acceleration). This provision shall not be subject to any cure period,
except with respect to prepayments under Section 4(c).

 

(b)          If
Borrower or Subsidiary fails to perform any other material obligation, covenant,
or agreement to Lender under this Note or any other Loan Document, or if there occurs a material event of default, whether by Borrower
or Subsidiary, under and as defined in any Loan Document (including, without limitation, any Collateral Document) or in any other
agreement, document, or instrument that has been given or in the future is given to Lender to evidence or secure any Lender Indebtedness.

 

    	 	-11-	 

     

    

 

(c)          If
any warranty or representation that Borrower or Subsidiary has made or in the future makes to Lender in this Note or any other
Loan Document, shall have been false in any material respect when made.

 

(d)          If
Borrower or Subsidiary dissolves, becomes insolvent, or makes an assignment for the benefit of creditors.

 

(e)          If
any Collateral Document shall for any reason fail to create a valid and perfected first priority security interest or mortgage
lien on any Collateral, except as permitted by the terms of such Collateral Document or due to any act or omission by Lender; if
any Collateral Document shall fail to remain in full force and effect without the consent of Lender; if Borrower, Subsidiary, or
any Affiliate of Borrower or Subsidiary takes any action to discontinue or to assert the invalidity or unenforceability of any
Collateral Document; or if any action by any other party successfully discontinues or successfully asserts the invalidity or unenforceability
of any such Collateral Document, including, without limitation, if any guaranty that now or in the future secures payment of all
or any part of the Lender Indebtedness is terminated or limited for any reason without the written consent of Lender.

 

(f)          If
any material provision in any other Loan Document shall for any reason cease to be valid, binding, and enforceable in accordance
with its terms; if Borrower, Subsidiary, or any Affiliate of Borrower or Subsidiary takes any action to discontinue or to assert
the invalidity or unenforceability of other Loan Document; or if any action by any other party successfully discontinues or successfully
asserts the invalidity or unenforceability of any such Loan Document.

 

(g)          If
Borrower defaults in the payment of any Indebtedness that Borrower at any time owes to any third party aggregating more than $5,000
and such default entitles the holder of the Indebtedness to accelerate Indebtedness of Borrower in excess of $50,000.

 

If an Event of Default is capable of being cured, then Borrower
may cure the same during the thirty-day period that begins on the date on which Borrower receives notice from Lender, or otherwise
has actual knowledge, of the event (the “Cure Period”). An Event of Default will not be deemed to have occurred
as a result of an event during the Cure Period for that event or, if the event is cured during the Cure Period, thereafter. Notwithstanding
anything else, no notice shall be required, and Borrower shall have no cure rights, with respect to a failure to perform any obligation
set forth in Sections 13(c)(1), (n) or (o) of this Note or any failure that is not capable of being cured.

  

Upon the occurrence of
any Event of Default, at the option of Lender, all or any part of the Indebtedness that this Note evidences and all or any part
of all other Lender Indebtedness and other obligations that Borrower then owes to Lender shall become immediately due and payable
without notice or demand, which Borrower waives. If (1) a voluntary or involuntary case in bankruptcy, receivership, or insolvency
is at any time begun by or against Borrower or Subsidiary and, if involuntary, is not dismissed within 60 days, or (2) any
levy, writ of attachment, garnishment, execution, or similar process is issued against or placed upon any property of Borrower
or Subsidiary (other than with respect to a Permitted Lien) and is not terminated or released within 60 days, then all Indebtedness
that this Note evidences and all other Lender Indebtedness and other obligations that Borrower then owes to Lender shall automatically
and without notice or demand, which Borrower waives, become immediately due and payable.

 

    	 	-12-	 

     

    

 

12.          Place
and Application of Payments. Principal and interest payments under this Note shall be paid by wire transfer of immediately
available funds pursuant to wire instructions provided by Lender to Borrower. Each payment under this Note may be applied in the
following order: accrued interest, principal, fees, charges, and advanced costs. If Borrower at any time owes Lender any Indebtedness
or obligation in addition to the Indebtedness that this Note evidences and if any Indebtedness that Borrower owes to Lender is
then in default, then any payment made by, or collected from, Borrower shall be applied first to amounts then due and payable under
this Note, except as the parties otherwise agree.

 

13.          Additional
Covenants. Until the Lender Indebtedness is repaid in full and Lender has no obligation to advance loans to Borrower, Borrower
shall:

 

(a)          Furnish
to Lender, within 120 days after the end of each of Borrower's fiscal years, beginning with its fiscal year ending December 31,
2016, an audited financial report prepared by CPAs in accordance with GAAP, containing: (1) Borrower's balance sheet as of the
end of that year, its related profit and loss and reconciliation of surplus statements for that year, and its statement of cash
flows for that year, together with any management letters that those CPAs prepare, and (2) all comments and financial details that
are customarily included in reports of that type.

 

(b)          Furnish
to Lender, within 45 days after the end of each fiscal quarter of Borrower, beginning with the fiscal quarter ending March 31,
2017, a financial report, the accuracy of which is certified to by a Certifying Agent, prepared in accordance with GAAP (subject
to GAAP Exceptions), containing Borrower's balance sheet as of the end of the period and its income statement showing the results
of its operations for the portion of its fiscal year then elapsed, and its statement of cash flows for the period.

 

(c)          (1)
Permit an agent of Lender reasonably acceptable to Borrower to observe all meetings of the board of directors of Borrower, and
(2) provide to Lender copies of all materials submitted to Borrower's board of directors in connection with such meetings as and
when such materials are provided to Borrower's board of directors, until such time after December 1, 2019, when the total amount
of the outstanding Lender Indebtedness is less than $5,000,000. Borrower shall also furnish to Lender, within 30 days after the
end of each calendar quarter, a statement of Borrower's financial performance as compared to Borrower's annual budget submitted
to Borrower's board of directors. The observer will execute a non-disclosure agreement in such form as is reasonably acceptable
to Borrower. Notwithstanding anything to the contrary in this subparagraph, Lender shall not receive materials, and the observer
shall be automatically recused from discussions by Borrower’s board of directors, that relate to customers or potential customers
of Borrower that are in competition with Lender or any projects relating to such competitive customers.

 

    	 	-13-	 

     

    

 

(d)          Promptly
inform Lender of the occurrence of any Event of Default or upon gaining knowledge of any event that could reasonably be expected
to be an Unmatured Event of Default or any event that has, or could reasonably be expected to have, a Material Adverse Effect;
grant or cause Subsidiary to grant to Lender and its representatives the right to examine Borrower's and Subsidiary's books and
records at any reasonable time or times; maintain and cause Subsidiary to maintain complete and accurate books and records of its
transactions in accordance with good accounting practices; and furnish or cause Subsidiary to furnish to Lender any information
that Lender reasonably requests concerning Borrower's or Subsidiary's financial affairs within 10 days after Lender requests that
information.

 

(e)          Pay
and discharge or cause to be paid and discharged, as often as they are due and payable, all taxes and assessments of whatever nature
that are levied or assessed against Borrower or Subsidiary or any of Borrower's or Subsidiary's properties, unless and to the extent
only that (1) in a jurisdiction where payment of taxes and assessments is abated during the period of any contest, those taxes
or assessments are being contested in good faith by appropriate proceedings, and (2) Borrower or Subsidiary shall have set
aside on its books adequate reserves with respect to those taxes and assessments.

 

(f)          Maintain
Borrower's and Subsidiary's existence in good standing in their current jurisdiction of organization and their qualification in
good standing in every other jurisdiction in which the failure to be qualified or authorized to do business could reasonably be
expected to have a Material Adverse Effect; continue to operate exclusively in the business of developing, manufacturing and selling
graphene nanoplatets, engineered products containing graphene nanoplatets, and similar products; and comply and cause Subsidiary
to comply in all material respects with all governmental laws, rules, regulations, and orders that apply to it.

 

(g)          Maintain
or cause to be maintained insurance, including, without limitation, "special form" (f/k/a "all risk") property
insurance, flood insurance (if required), workers' compensation insurance, and commercial general liability coverage with responsible
insurance companies on its and Subsidiary's properties, including, without limitation, the Collateral, and against the risks and
in the amounts required by the Collateral Documents (or, in the absence of a requirement, that similar businesses customarily maintain);
(2) furnish to Lender upon its request the details with respect to that insurance and satisfactory evidence of that insurance coverage;
and (3) within 60 days after Lender requests, obtain or cause to be obtained any additional insurance that Lender reasonably requests.
As soon after closing as is reasonably practicable, each insurance policy that this Section 13(g) requires shall be written
or endorsed in a manner that makes losses, if any, payable to Borrower and Lender or Subsidiary and Lender, as applicable, as their
respective interests appear and shall include, as applicable, an additional insured endorsement or a standard mortgage clause or
standard lender's loss payable endorsement in favor of Lender in form and substance satisfactory to Lender.

 

(h)          Act
prudently and in accordance with customary industry standards in managing and operating its assets, properties, business, and investments;
and use commercially reasonable efforts to keep in good working order and condition, ordinary wear and tear excepted, all of its
tangible assets and properties that are necessary to the conduct of its business.

 

    	 	-14-	 

     

    

 

(i)           Engage,
and cause Subsidiary to engage, in good faith discussions with Lender regarding Borrower's provision to Lender, with favored pricing,
of technology rights and/or volume supply commitments; and engage, and cause Subsidiary to engage, in good faith discussions with
Lender regarding the out-license of graphene related technology to Lender.

 

(j)           Not
make loans or advances to any individuals or entities in excess of $5,000 in the aggregate, other than with respect to accounts
receivable incurred in the ordinary course of business.

 

(k)          Not
guarantee, endorse, assume, or otherwise incur or suffer to exist any contingent liability in respect of any obligation of any
other individual or entity, except in favor of Lender or by the endorsement of negotiable instruments for deposit or collection
in the ordinary course of business.

 

(l)           Not
issue, incur, assume, or permit to remain outstanding any Indebtedness in excess of $200,000 in the aggregate, or allow Subsidiary
to do so, except for Subordinated Indebtedness, Lender Indebtedness, and Indebtedness secured by Purchase Money and Lease Liens
(subject to the limitations set forth in the definition of Purchase Money and Lease Liens in Section 1 of this Note).

 

(m)         Not
enter into any merger, consolidation, reorganization, or recapitalization, or purchase or otherwise acquire all, or substantially
all, of the assets, obligations, or capital stock or other ownership interests of any entity; or amend, modify, or waive any of
its rights under, its articles of incorporation, bylaws, any shareholder agreement relating to shares of Borrower, or any other
charter documents; unless in any such case Lender consents in writing, which consent shall not be unreasonably withheld.

 

(n)          Not
permit Subsidiary to enter into any merger, consolidation, reorganization, or recapitalization, or purchase or otherwise acquire
all, or substantially all, of the assets, obligations, or membership interest or other ownership interests of any entity; or amend,
modify, or waive any of Subsidiary's rights under, Subsidiary's articles of organization, operating agreement, or any other charter
documents; unless in any such case Lender consents in writing, which consent shall not be unreasonably withheld.

 

(o)          Not,

related to such Indebtedness.

 

    	 	-15-	 

     

    

 

(p)          Not,
and not permit Subsidiary to, change its name, fiscal year, or method of accounting, except as GAAP requires; provided, however,
that Borrower or Subsidiary may change its name if Borrower or Subsidiary gives Lender 60 days' prior written notice of the
name change and takes any action that Lender considers necessary to continue the perfection of the security interests and liens
that the Collateral Documents may in the future grant to Lender.

 

(q)          Not,
and not permit Subsidiary to, engage in any transaction with an Affiliate on terms that are less favorable to Borrower or Subsidiary
than Borrower or Subsidiary could obtain at the time in a comparable transaction in an arm's-length dealing with an individual
or entity other than an Affiliate.

 

(r)          Not
permit to occur any change in the ownership of Subsidiary.

 

(s)          Not
make any payment to any shareholder of Borrower, whether in connection with a dividend, stock redemption, or otherwise, except

equity in Borrower), or (3) with Lender's prior written consent.

 

(t)          Not
sell or out-license any assets of Borrower of Subsidiary, other than in the ordinary course of business, which shall be deemed
to include the licensing of intellectual property, entering into joint development projects, and other related activities in the
ordinary course of business or in connection with strategic initiatives approved by the board of directors of Borrower, in which
case Lender will be informed in advance (unless a memorandum of understanding, term sheet, letter of intent, or similar agreement
is signed, then at that time) in writing by Borrower.

 

(u)          Notify
Lender in writing within 10 days after Borrower or any Affiliate of Borrower receives any notice of the beginning of (1) any
proceeding or investigation by a federal or state environmental agency against Borrower or the Affiliate, or (2) any other
judicial or administrative proceeding or litigation by or against Borrower or any Affiliate that, if adversely decided, could reasonably
be expected to have a Material Adverse Effect.

 

(v)         Sign
and deliver, or cause to be signed and delivered, any and all other agreements, instruments, assurances, or other documentation,
and take, or caused to be taken, all other action, as Lender deems necessary in its reasonable discretion from time to time to
give full effect to the Loan Documents and the transactions contemplated by this Note.

 

Notwithstanding the foregoing,
neither the covenants in this Section 13 nor in any Loan Document shall prohibit Borrower from licensing its intellectual
property, entering into joint development projects, or other related activities in the ordinary course of business or in connection
with strategic initiatives approved by the board of directors of Borrower, in which case Lender will be informed in advance (unless
a memorandum of understanding, term sheet, letter of intent, or similar agreement is signed, then at that time) in writing by Borrower.

 

    	 	-16-	 

     

    

 

14.          Remedies.
Lender shall have all rights and remedies provided by law and by agreement of Borrower or Subsidiary. Lender shall have the right
at any time to set off any indebtedness that Lender then owes to Borrower against any Lender Indebtedness that is then due and
payable. Lender shall also have all rights and remedies set forth in each other Loan Document.

 

15.          Fees
and Expenses. Borrower shall pay, or reimburse Lender for, all expenses incurred by Lender (including, but not limited to,
search fees and fees and expenses of legal counsel, other professional advisers, consultants and experts) in connection with (1)
the negotiation, preparation, and execution of this Note and the other Loan Documents (including legal fees not to exceed $25,000),
each amendment to, or waiver of any provision of, this Note and the other Loan Documents, and each refinancing or restructuring
of this Note, (2) the administration of this Note and the other Loan Documents, including, without limitation, making filings and
recordings in public offices to perfect or give notice of liens in favor of Lender and obtaining financing statement searches,
tax lien searches, inspections, audits, and assessments, (3) obtaining advice of counsel or other professional advisers, consultants,
and experts regarding any aspect of this Note and the other Loan Documents, (4) the enforcement of any provision of this Note or
the other Loan Documents, and (5) the collection of any amount at any time owing to Lender by Borrower under this Note or the other
Loan Documents.

 

16.          Relationship.
The relationship between Borrower and Lender under this Note is solely that of debtor and creditor. Lender does not have any fiduciary
responsibilities to Borrower. Lender does not and shall not have any responsibility to review, or to inform Borrower of any matter
in connection with, any aspect of Borrower's business, operations, or properties or any other security for the Lender Indebtedness.
Borrower shall rely entirely upon its own judgment with respect to each such matter.

 

17.          Waivers.
No delay by Lender in the exercise of any right or remedy shall be a waiver of that right or remedy. No single or partial exercise
by Lender of any right or remedy shall preclude any other or future exercise of that or any other right or remedy. No waiver by
Lender of any default or of any provision of this Note or the other Loan Documents shall be effective unless it is in writing and
signed by Lender. No waiver of any right or remedy on one occasion shall be a waiver of that right or remedy on any future occasion.
Borrower waives demand for payment, presentment, notice of dishonor, and protest of this Note and consents to any extension or
postponement of time of its payment.

 

18.          Notices.
Any notice or other communication that this Note requires or permits shall be in writing and shall be served either personally,

THIS SECURITY AGREEMENT
(“Agreement”) is made as of __________, by and between XG Sciences, Inc., a Michigan corporation,
of 3101 Grand Oak Drive, Lansing, Michigan 48911 (“Debtor”), and The Dow Chemical Company, of 2030 Dow Center,
Midland, Michigan 48674 (“Secured Party”), for itself and as agent for the benefit of all other affiliates of
Secured Party (each, an “Affiliate”), pursuant to a certain Draw Loan Note and Agreement (as amended, supplemented,
restated or otherwise modified from time to time, “Note”) dated as of December 7, 2016, between Debtor
and Secured Party.

 

1.           Grant
of Security Interest. Debtor grants to Secured Party a continuing security interest in all business assets of Debtor, including
without limitation:

 

(a)          all
machinery and equipment (including vehicles) and fixtures, wherever located, whether now owned or hereafter acquired by Debtor,
and all chattel paper evidencing any past, present or future leasing of the machinery, equipment or fixtures;

 

(b)          all
inventory, wherever located, whether now owned or hereafter acquired by Debtor; and any and all bills of lading, warehouse receipts
and other documents of title evidencing inventory; all rights of stoppage in transit of inventory; all chattel paper evidencing
any past, present or future leasing of inventory; and all letter of credit rights under all existing and future letters of credit

accounts, contract rights, chattel paper, instruments, investment property, general intangibles and letter of credit rights, wherever
located, whether now owned or hereafter acquired by Debtor;

 

(d)          all
deposit accounts, wherever located, whether now owned or hereafter acquired by Debtor;

 

(e)          all
trademarks, trade names, corporate names, business names, domain names, trade styles, trade dress, service marks, logos, source
identifiers, business identifiers, or designs of like nature now held or hereafter acquired by Debtor, any registration or recording
of the foregoing or any thereof, and any application in connection therewith, including without limitation, any such registration,

or agency of the United States, any state thereof or any country or political subdivision of such other country, and all extensions
or renewals of any of the foregoing;

 

(f)          any
letters patent of the United States or any country in which Debtor now or hereafter has title, all reissues, divisionals, continuations,
continuations-in-part, and extensions thereof, as well as any application for a letters patent in the United States or any other
country now or hereafter owned by Debtor, and all extensions or renewals of any of the foregoing;

 

     

     

    

 

(g)          any
copyright, copyrightable work, any registration or recording of any copyright or any copyrightable work to which Debtor now or
hereafter has title, and any application in connection with any copyright or copyrightable work owned by Debtor, including without
limitation, any such registration, recording or application in the United States Copyright Office or in any similar office or agency

(h)          all
know-how  trade secrets and business information, whether now owned or hereafter acquired by Debtor; 

 

(i)           all

together with (i) all proceeds of
the foregoing, including, without limitation, all cash, checks, drafts, accounts receivable, chattel paper, leases and instruments
received by Debtor in connection with any sale, lease, exchange or other disposition of any of the foregoing, and (ii) all
books, records (including computer software), and documents at any time evidencing or relating to any of the foregoing or any
proceeds thereof. All of the foregoing properties and assets of Debtor are referred to collectively in this Agreement as the “Collateral.”
Notwithstanding anything contained herein to the contrary, the term “Collateral” does not and shall not include
any patent rights within the meaning of that certain Restated and Amended Exclusive License Agreement between Michigan State University
and Debtor. 

 

2.           Indebtedness
Secured. The foregoing security interest is given to secure payment and performance of ALL OBLIGATIONS AND INDEBTEDNESS THAT
DEBTOR NOW AND IN THE FUTURE OWES TO SECURED PARTY AND ANY AFFILIATE under this Agreement and the Note, as well as under all other
security agreements, pledge agreements, assignments, mortgages, guaranties, notes, loan agreements, and other agreements, instruments
and documents that Debtor has signed or in the future signs relating thereto, and all extensions and renewals of such indebtedness
and obligations.

 

The indebtedness and obligations that this
Agreement secures are collectively called the “Indebtedness.”

 

3.           Warranties,
Representations, and Agreements. Debtor warrants and represents to Secured Party, and agrees, as follows:

 

(a)          Debtor
is the owner, leasee or licensee of the Collateral, and none of the Collateral is subject to a lien, security interest, encumbrance
or claim in favor of a third party (other than Subsidiary), and no financing statement is on file in a public office covering any
of the Collateral, except in favor of Secured Party or with respect to Permitted Liens, and except that certain financing statement
No. 2013142779-9 in favor of NMHG Financial Services, Inc., which Debtor shall cause to be discharged within 30 days of this Agreement.

  

    	 	2	 

     

    

 

(b)          Debtor
has full power and authority to enter into and perform its obligations under this Agreement.

 

(c)          This
Agreement is the valid and binding obligation of Debtor and is enforceable against Debtor in accordance with its terms.

 

(d)          All
information that Debtor has furnished or in the future furnishes to Secured Party concerning the Collateral, including, without
limitation, all information concerning the condition and quality of the Collateral, is and will be correct and complete.

 

(e)          Debtor’s
exact legal name is set forth in the first paragraph of this Agreement.

 

(f)          Debtor’s
address set forth on the first page of this Agreement is the location of Debtor’s chief executive office.

 

(g)          Any
part of the Collateral that consists of accounts or chattel paper does and shall evidence bona fide sales or leases to the parties
named in Debtor’s books, and Debtor is not aware of any existing defense to any account or chattel paper.

 

(h)          Exhibit
A to this Agreement contains a complete and accurate list of all of Debtor’s and its Subsidiary’s United States
intellectual property registrations, recordings and applications. Debtor shall provide Secured Party with an updated Exhibit A
(1) within thirty (30) days after the date of this Agreement to list international intellectual property registrations, recordings
and applications, and (2) from time to time for any additions or deletions to such list occurring after the date of this Agreement.
Except as disclosed on Exhibit A and except for business information, know-how and trade secrets, there is no intellectual property
that is material to Obligor or Borrower.

 

(i)           Each
current employee of Debtor is bound by a nondisclosure agreement in form and substance previously disclosed to Secured Party. 

 

    	 	3	 

     

    

 

4.           Agreements
of Debtor. Debtor agrees that:

 

(a)          Debtor
shall not cause or permit any lien, security interest or encumbrance to be placed on any Collateral (other than Permitted Liens),
except in favor of Secured Party and Debtor shall not sell, assign or transfer any Collateral or permit any Collateral to be transferred
by operation of law, except for any intellectual property assigned to Subsidiary, as permitted under the Note and sales of inventory
in the ordinary course of Debtor’s business. A sale in the ordinary course of business does not include a transfer in partial
or complete satisfaction of a debt.

 

(b)          Debtor
shall maintain all records concerning the Collateral at Debtor’s chief executive office.

 

(c)          Debtor
shall furnish to Secured Party all information regarding the Collateral that Secured Party from time to time reasonably requests
and shall allow Secured Party at any reasonable time to inspect the Collateral and Debtor’s records regarding the Collateral.

 

(d)          Debtor
shall sign, file, record or obtain from third persons all subordination agreements and other documents, and shall take all other
actions, that Secured Party reasonably considers necessary or appropriate to perfect, to continue perfection of, or to maintain
first priority (except with respect to Permitted Liens) of, Secured Party’s security interest in the Collateral and Debtor
shall place upon the Collateral and/or documents evidencing the Collateral any notice of Secured Party’s security interest
that Secured Party from time to time reasonably requires. Actions that Secured Party may require Debtor to take under
the preceding sentence include, without limitation, (1) obtaining from any third party who has possession of Collateral an acknowledgment
that the third party holds the Collateral for Secured Party and (2) obtaining agreements from banks, securities intermediaries,
issuers of letters of credit and others, and taking all other actions reasonably requested by Secured Party, to give Secured Party
control of any part of the Collateral consisting of investment property, deposit accounts, letter of credit rights or electronic
chattel paper.

 

(e)          Debtor
shall immediately notify Secured Party in writing of any change in Debtor’s name, identity or organizational structure, and
of any change in the location of Debtor’s place of business and of the location of each additional place of business that
Debtor establishes. Debtor shall not make a change in its name or its organizational structure or in the jurisdiction under the
laws of which Debtor is organized, without Secured Party’s prior written consent.

 

(f)          Debtor
shall indemnify Secured Party with respect to all losses, damages, liabilities and expenses (including attorney fees) that Secured
Party incurs by reason of a failure of Debtor to comply with an obligation under this Agreement or by reason of a warranty or representation
that Debtor makes to Secured Party in this Agreement being false in any material respect.

 

    	 	4	 

     

    

 

(g)          After
the occurrence of an Event of Default (subject to applicable cure periods), Debtor shall take all steps reasonably necessary to
permit Secured Party to contact its account debtors at any time for the purpose of verifying the existence, amount and collectability
of, and other information regarding, Debtor’s accounts, chattel paper, instruments or general intangibles.

 

(h)          Debtor
shall maintain all tangible Collateral in good condition and repair and maintain special form, replacement cost property insurance
covering all tangible Collateral. As soon after closing as reasonably practicable, but no later than 30 days after closing,
each insurance policy (1) shall provide that its proceeds shall be payable to Secured Party to the extent of Secured Party's
interest in the Collateral, (2) shall contain a standard lender's loss payable endorsement in favor of Secured Party, (3) shall
provide that the policy shall not be canceled, and the coverage shall not be reduced, without at least 10 days' prior written notice
by the insurer to Secured Party and (4) shall otherwise be in form and substance satisfactory to Secured Party. Debtor shall provide
Secured Party evidence of that insurance coverage. Upon Secured Party's request, Debtor shall deliver to Secured Party all policies
that provide for such insurance. Debtor agrees that Secured Party may act as agent for Debtor in obtaining, adjusting, and settling
that insurance and endorsing any draft evidencing proceeds of it.

 

(i)           To
the extent that applicable law at any time permits a secured party to file a financing statement that is not authenticated by Debtor,
Debtor authorizes Secured Party to file one or more financing statements containing an indication that such financing statement
covers the Collateral. The financing statements that Secured Party files to perfect its security interest in the Collateral may
describe the Collateral as “all assets” or “all personal property” that Debtor now owns or acquires in
the future. If Secured Party has previously filed one or more financing statements to perfect its security interest in the Collateral,
then Debtor approves and ratifies those filings.

 

(j)           Debtor
shall pay, before they become delinquent, all taxes and assessments upon the Collateral or for its use or operation and pay and
perform when due all indebtedness and obligations under all leases, land contracts or other agreements under which Debtor has possession
of any real property upon which any of the Collateral is at any time located and under any mortgage or mortgages at any time covering
that real property.

 

(k)          Debtor
shall prepare, execute, acknowledge and deliver to Secured Party an instrument in writing in recordable form for recording a lien
on and security interest in and to all of its right, title and interest in, to and under all new patent and trademark application
filings and any rights extending therefrom, either in the United States or any other country and all proceeds of any and all of
the foregoing, within one month after the filing of any such applications.

 

(l)           Debtor
shall timely enter into a nondisclosure agreement, in form and substance reasonably acceptable to Secured Party, with each new
employee, manager, director, and officer of Debtor, and all agents and other parties to whom trade secrets or other confidential
information of Debtor or any affiliate of Debtor may be disclosed.

 

    	 	5	 

     

    

 

(m)         Debtor
shall not commit any material breach or default under that certain license agreement between Debtor and Michigan State University
dated as of July 27, 2007 and amended on May 24, 2010 and May 27, 2011, as it may be amended, restated, renewed, extended, replaced,
or modified.

 

5.           Secured
Party’s Right to Perform. If Debtor fails to perform an obligation of Debtor under this Agreement, then Secured Party
may, without giving notice to or obtaining the consent of Debtor, perform that obligation on behalf of Debtor. Debtor shall reimburse
Secured Party on demand for any expense that Secured Party incurs in performing the obligation and shall pay to Secured Party interest
on each expense, from the date the expense was incurred by Secured Party, at 5% per annum (“Default Rate”).
Secured Party is not required to perform an obligation that Debtor has failed to perform. If Secured Party does so, then that shall
not be a waiver of Secured Party’s right to declare the Indebtedness immediately due and payable by reason of Debtor’s
failure to perform.

 

6.           Events
of Default and Acceleration. Any part or all of the Indebtedness shall, at the option of Secured Party, become immediately
due and payable without notice or demand upon the occurrence of any of the following events of default (each, an “Event
of Default”):

 

(a)          If
an Event of Default occurs under and as defined in the Note, including any default in the payment or performance of any of the
Indebtedness, when and as it is due and payable subject to applicable grace periods.

 

(b)          If
Debtor fails     to perform any other material obligation, covenant or agreement of Debtor to Secured Party under
this Agreement, under a promissory note or other instrument that at any time evidences any Indebtedness or under any other security
agreement, loan agreement, mortgage, assignment, guaranty or other agreement that now or in the future secures or relates to any
Indebtedness (“Security Documents”).

 

(c)          If
a warranty, representation, or statement that has been or in the future is made to Secured Party by Debtor or by a guarantor of
all or part of the Indebtedness (“Guarantor”) in this Agreement or in a Security Document shall have been false
in any material respect when made or furnished.

 

(d)          If
Debtor or a Guarantor dissolves, becomes insolvent or makes an assignment for the benefit of creditors.

 

(e)          If
a guaranty that now or in the future secures payment or performance of all or a part of the Indebtedness is terminated, revoked
or limited for any reason, without Secured Party’s written consent or agreement.

 

    	 	6	 

     

    

 

(f)          If
an attachment, garnishment, levy, execution or other legal process is at any time issued against or placed upon any of the Collateral
(other than with respect to Permitted Liens) and is not terminated or released within 30 days.

 

(g)          If
all or a substantial part of the tangible Collateral is destroyed or materially damaged by fire or other casualty, and cannot be
repaired or replaced within a commercially reasonable time, not to exceed 90 days, whether or not there is insurance coverage for
the damage or destruction.

 

If an      Event of Default  is
capable of being cured, then Debtor may cure the same during the thirty-day period that begins on the date on which Debtor
receives notice from Secured Party or otherwise has actual knowledge,  of the event  (the “Cure Period”). An Event of Default that is capable of being cured will not be deemed to
have occurred as a result of an event during the Cure Period for that event or, if the event is cured during the Cure
Period, thereafter.

 

If a voluntary or involuntary case in bankruptcy,
receivership or insolvency is at any time begun by or against Debtor or a Guarantor or if any attachment, garnishment, levy, execution
or other legal process is at any time issued against or placed upon Collateral and not terminated or released within 30 days, then
the entire Indebtedness shall automatically become immediately due and payable, without notice or demand. All or part of the Indebtedness
also may become, or may be declared to be, immediately due and payable under the terms of the Note or a note that at any
time evidences any Indebtedness or under a Security Document that has been or in the future is entered into between Debtor and
Secured Party.

 

7.           Secured
Party’s Rights and Remedies. Secured Party shall have all rights and remedies of a secured party under applicable laws.
Without limiting those rights and remedies, upon the occurrence of an Event of Default (subject to applicable cure periods):

 

(a)          (1)
Without notice or demand to Debtor, Secured Party shall be entitled to notify Debtor’s account debtors and obligors to make
all payments directly to Secured Party, and Secured Party shall have the right to take all actions that Secured Party reasonably
considers necessary or desirable to collect upon the Collateral, including, without limitation, prosecuting actions against, or
settling or compromising disputes and claims with, Debtor’s account debtors and obligors, (2) without notice or demand
to Debtor, Secured Party may receive, open, dispose of and notify the postal authorities to change the address of, mail directed
to Debtor, and (3) upon Secured Party’s demand, Debtor shall immediately deliver to Secured Party, at the place that
Secured Party designates, all proceeds of the Collateral and all books, records, agreements, leases, documents and instruments
that evidence or relate to the Collateral.

 

(b)          Debtor,
upon Secured Party’s demand, shall assemble the Collateral and proceeds of Collateral at Debtor’s place of business,
and Secured Party may dispose of the Collateral in any commercially reasonable manner. Any notification that Secured Party is required
to give to Debtor regarding sale or other disposition of Collateral shall be considered reasonable if it is mailed at least 10
days before the sale or other disposition. In connection with a disposition of Collateral, Secured Party may comply with the requirements
of an applicable state or federal law or regulation, and such compliance shall not cause the disposition to not be commercially
reasonable.

 

    	 	7	 

     

    

 

(c)          Secured
Party shall have the right (but no obligation) to continue or complete the manufacturing or processing of, or other operations
in connection with, any part of the Collateral, and, for that purpose, to enter and remain upon or in any land or buildings
that are possessed by Debtor or that Debtor has the right to possess. Debtor shall reimburse Secured Party on demand for any net
expense that Secured Party incurs in connection with those activities and shall pay to Secured Party interest on each net expense,
from the date on which Secured Party incurred the expense, at the Default Rate.

 

The proceeds of any collection or disposition
of Collateral shall be applied first to Secured Party's attorney fees and expenses, as provided in Paragraph 8 of this Agreement,
then to the unpaid interest accrued on the Indebtedness and then to the principal of the Indebtedness, and Debtor shall be liable
for any deficiency. Secured Party does not have any obligation to prepare or process any Collateral for sale or other disposition.
If Secured Party sells any of the Collateral on credit, then Debtor will be credited only with payments that the purchaser actually
makes and that Secured Party receives and applies to the unpaid balance of the purchase price of the Collateral. If the purchaser
fails to pay for the Collateral, then Secured Party may again dispose of the Collateral and apply the proceeds in accordance with
this paragraph. All rights and remedies of Secured Party under this Agreement, whether or not exercisable only on default, shall
be cumulative and may be exercised from time to time. No delay by Secured Party in the exercise of any right or remedy shall operate
as a waiver thereof, and no single or partial exercise of any right or remedy shall preclude other or further exercise thereof
or the exercise of any other right or remedy.

 

8.           Expenses.
Debtor shall reimburse Secured Party on demand for all reasonable attorney fees, legal expenses, and other expenses that Secured
Party incurs in perfecting (subject to the $25,000 limitation in the Note), protecting and enforcing its interest in the Collateral
and its rights under this Agreement. This includes fees and expenses incurred in trying to take possession of Collateral from Debtor,
a trustee or receiver in bankruptcy, or any other person. Secured Party may apply any proceeds of collection or disposition of
Collateral to Secured Party's attorney fees, legal expenses and other out-of-pocket expenses.

 

9.           Amendments
and Waivers. No provision of this Agreement may be modified or waived except by a written agreement signed by Secured
Party and Debtor. Secured Party will continue to have all of its rights under this Agreement even if it does not fully and
promptly exercise them on all occasions. Secured Party may, at its option: waive any default; defer an action on any default; extend
or modify the time or manner of payment of the Indebtedness or waive or modify any term or condition relating to the Indebtedness;
release Collateral or other security for the Indebtedness; release any person liable for any of the Indebtedness, including Debtor;
or make advances or other extensions of credit secured hereby; all without giving Debtor notice or obtaining Debtor's consent.
Any such action by Secured Party will not release or impair its security interest in the Collateral or Debtor's obligations
under this Agreement. Secured Party's security interest in the Collateral and Debtor's obligations under this Agreement will not
be released or impaired if Secured Party fails to obtain, perfect, or secure priority of any other security for the Indebtedness
that is agreed to be given, or is given, by anyone else. Secured Party is not required to sue upon or otherwise enforce payment
of the Indebtedness or any other security before exercising its rights under this Agreement.

 

    	 	8	 

     

    

 

10.         Notices.
Any notices or communications required or permitted under this Agreement shall be governed by the Note.

 

11.         Terminology;
Conflicts. Capitalized terms that are not otherwise defined in this Agreement shall have the meanings set forth in the Note.
Other terms used in this Agreement shall have the meanings set forth in the Uniform Commercial Code as in effect in the State of
Michigan on the date of this Agreement. In the event of a conflict between the terms of this Agreement and the Note, the terms
of the Note control.

 

12.         Binding
Effect. This Agreement shall be binding upon and inure to the benefit of Debtor and Secured Party and their respective successors
and assigns.

 

13.         Termination.
Upon the payment in full and termination of the Note and the Security Documents, this Agreement shall terminate and Secured
Party shall execute, acknowledge and deliver to Debtor an instrument in writing, prepared by debtor, in recordable

Exhibit A

 

List of Intellectual Property

 

Michigan State University License

 

We have acquired an exclusive license for a number of
inventions from Michigan State University. These rights are embodied in a Technology Licensing Agreement between XGS and
Michigan State University dated July 27, 2007 and amended on May 24, 2010 and May 27, 2011, which owns the rights to all
intellectual property resulting from research performed at the University. This Agreement gives us the exclusive worldwide
rights to the subject intellectual property in its field. In exchange for the rights to the technology covered by this
Agreement, we paid MSU an initial fee and agreed to pay ongoing royalties on the basis of material sold by us in future
years. Under a previous version of the Licensing Agreement, we also awarded a small amount of common stock to MSU. The
intellectual property covered by the Agreement is in various stages of development and legal protection. Because there is an
active research program underway in this area, we also anticipate that we may add other MSU inventions to our Agreement. In
some limited cases, depending on the source of research funds, other parties may have limited rights to use the inventions
covered by these agreements. This is typical in the case of research funded by U.S. government agencies and is sometimes the
case when research has been funded or partially funded by private corporations.

 

As of November 1, 2016 the following technologies were included
in the MSU License Agreements with XGS and were being actively prosecuted at the U.S. Patent Office:

 

		·	U.S. Patent Application No. 12/587,645. “Electrically Conductive, Optically Transparent Films of Exfoliated Graphite

XG, LLC and in (1) all securities, equity interests, membership interests, security entitlements and other financial assets,
instruments and other property (“Additional Property”) that Debtor at any time receives or is entitled to receive
by reason of a dividend, equity split, recapitalization, reclassification, merger, consolidation, liquidation, exchange, renewal,

to in this Agreement as “Collateral.”

 

2.          Indebtedness
Secured. Debtor gives this security interest to secure payment and performance of ALL OBLIGATIONS AND INDEBTEDNESS THAT
DEBTOR NOW AND IN THE FUTURE OWES TO SECURED PARTY AND ANY AFFILIATE under this Agreement, and the Note, as well as under all
other agreements, instruments and documents that Debtor has signed or in the future signs relating thereto, and all extensions
or renewals of that indebtedness and obligations.

 

The indebtedness and obligations
that this security interest secures are collectively called the “Indebtedness.”

 

3.          Warranties
and Representations. Debtor represents and warrants to, and agrees with, Secured Party as follows:

 

(a)          Debtor
owns the Collateral and has the unqualified right to transfer the Collateral to Secured Party, and it is not subject to a lien,
encumbrance or other claim in favor of a third party, or to a right or option of a third party to acquire Collateral.

 

(b)          Each
instrument, security and other financial asset included in the Collateral is genuine and what it purports to be and has not been
materially altered. Each security included in the Collateral is validly issued, fully paid and not subject to calls or assessments.

 

     

     

    

 

(c)          Debtor’s
address on the first page of this Agreement is the location of Debtor’s chief executive office.

 

(d)          Debtor
is a corporation and is incorporated and validly existing in good standing under the laws of the State of Michigan; Debtor has
full power and authority to enter into and perform its obligations under this Agreement; the signing, delivery and performance
of this Agreement have been duly authorized by all necessary action of Debtor’s shareholders and directors and will not violate
XG, LLC’s operating agreement.

 

(e)          Debtor
at all times during the terms of this Agreement will own 100% of the outstanding membership interests of XG, LLC.

 

4.          Agreements
of Debtor. Debtor agrees that:

 

(a)          Debtor
must not sell, lease, transfer or assign Collateral or an interest in Collateral or permit Collateral to be transferred by operation
of law.

 

(b)          Debtor
must pay promptly when due all taxes and assessments upon the Collateral or for its use or ownership.

 

(c)          Debtor
must furnish to Secured Party all information regarding the Collateral that Secured Party requests and must allow Secured Party

    	 	-2-	 

     

    

 

(c)          Without
limitation of any other provision of this Agreement, if any of the Collateral of Debtor (whether now owned or hereafter acquired)
which is intended to be subjected to the security interests hereof is an uncertificated security, Debtor shall, as soon as reasonably
practicable after closing, cause XG, LLC to create a registration book for the registration of each such “uncertificated
security” and duly register Debtor as the owner and note the pledge in favor of Secured Party in a manner that provides control
with respect to such uncertificated security. Debtor further agrees to take such actions as the Secured Party deems reasonably
necessary or desirable to effect the foregoing and to permit the Secured Party to exercise any of its rights and remedies hereunder
in respect thereof, and agrees to provide an opinion of counsel reasonably satisfactory to the Secured Party with respect to any
such pledge of any of the securities described above, promptly upon the request of the Secured Party. Debtor further agrees not
to amend the operating agreement of XG, LLC in a manner that results in an “opt out” of Article 8 of the Michigan Uniform
Commercial Code.

 

6.          Secured
Party’s Rights.

 

(a)          If
Debtor fails to perform an obligation of Debtor under this Agreement, then Secured Party may, without giving Debtor notice, to
or obtaining Debtor’s consent, perform that obligation on Debtor’s behalf. Debtor must reimburse Secured Party on demand
for each expense that Secured Party incurs in performing an obligation and must pay to Secured Party interest on the expense, from
the date on which Secured Party incurred the expense, at an annual rate equal to 5 percent.

 

Secured Party is
not required to perform an obligation that Debtor has failed to perform. If Secured Party does so, then that will not be a waiver
of Secured Party’s right to declare the Indebtedness immediately due and payable because of Debtor’s failure to perform.

 

(b)          With
respect to the custody and preservation of Collateral in its possession, Secured Party’s only duty will be to use reasonable
care. Secured Party will not have an obligation to take steps necessary to preserve rights against prior parties. Secured Party
will not have a duty to sell Collateral even if its value declines. Secured Party must not have an obligation to exercise, or to
notify Debtor of, a conversion or redemption right or to take similar action with regard to any Collateral.

 

    	 	-3-	 

     

    

 

(c)          Each
of Debtor and XG, LLC agrees to comply with all instructions originated by Secured Party directing it to transfer, redeem or
otherwise act with respect to the Collateral (“Instructions”), subject to this Section 6(c) and the other
provisions of this Agreement. Prior to the occurrence of an Event of Default, Instructions shall require the consent of
Debtor. After the occurrence of an Event of Default, Instructions shall not require the consent of Debtor except to the
extent required by MCL 440.9620 (Acceptance of collateral in full or partial satisfaction of obligation; compulsory
disposition of collateral).

 

7.          Default
and Acceleration. If any of the following (each an “Event of Default”) occurs, then the Indebtedness will,
at Secured Party's option, become immediately due and payable, without notice or demand to Debtor:

 

(a)          If
an Event of Default shall occur under and as defined in the Note, including any default in the payment or performance of all or
part of the Indebtedness, when and as it is due and payable subject to applicable grace periods.

 

(b)          If
Debtor fails  to perform any other material obligation, covenant or agreement of Debtor under this Agreement or
under another security agreement, loan agreement, mortgage, assignment, guaranty or other agreement that now or in the future secures
or relates to the Indebtedness (“Security Documents”).

 

(c)          If
a warranty, representation or other statement that has been or in the future is made to Secured Party by Debtor, XG, LLC, or by
a guarantor of all or part of the Indebtedness (“Guarantor”) in this Agreement or in a Security Document, shall
have been false in a material respect when made or furnished.

 

(d)          If
a lien, security interest or other encumbrance or a writ of attachment, garnishment, levy, execution or other legal process is
at any time issued against or placed upon the Collateral and is not terminated or released within 30 days.

 

(e)          If
Debtor or a Guarantor dissolves, becomes insolvent, or makes an assignment for the benefit of creditors.

 

(f)          If
a guaranty that now or in the future secures payment or performance of the Indebtedness is terminated or limited, without the written
consent or agreement of Secured Party.

 

    	 	-4-	 

     

    

 

(g)          If
the issuer of or obligor on the Collateral materially defaults in an obligation of the issuer or obligor under the terms of that
Collateral or under an agreement that gives Secured Party control over the Collateral or if a warranty or representation made by
the issuer or obligor in such an agreement shall have been false in a material respect or if a petition for relief is filed by
or against the issuer or obligor under the federal Bankruptcy Code.

 

(h)          If
a securities intermediary materially defaults in the performance of an obligation under an existing or future agreement that gives
Secured Party control over Collateral or if a warranty or representation that the securities intermediary in any such agreement
shall have been false in a material respect when made or if a petition for relief is filed by or against the securities intermediary
under the federal Bankruptcy Code.

 

(i)          If
an  Event of Default  is capable of being cured, then Debtor may cure the same during the thirty-day period that begins on
the date on which Debtor receives notice from Secured Party or otherwise has actual knowledge,  of the event  (the “Cure Period”). An Event of Default will not be deemed to have
occurred as a result of an event during the Cure Period for that event or, if the event is cured during the Cure Period,
thereafter.

 

If a voluntary or involuntary
case in bankruptcy, receivership or insolvency is begun by or against Debtor or any Guarantor, and not terminated or released within
30 days, then the entire Indebtedness will automatically become immediately due and payable, without notice or demand. The Indebtedness
also may become immediately due and payable under the terms of a note that at any time evidences the Indebtedness or of a Security
Document that has been or in the future is entered into between Debtor and Secured Party.

 

8.          Remedies.
Secured Party shall have all of the rights and remedies of a secured party under applicable law. All rights and remedies of Secured
Party are cumulative and may be exercised from time to time. Without limiting those rights and remedies, upon the occurrence of
an Event of Default (subject to applicable cure periods), then:

 

(a)          Subject
to Section 6(a) above, Secured Party shall have the right, but no obligation, without notice to Debtor and without
Debtor’s consent, to vote or give consent with regard to any of the collateral that consists of securities.  Secured Party
will have the right, but no obligation, (1) to revoke and terminate rights that Secured Party shall have given to Debtor, or
permitted Debtor to retain, to control any uncertificated security, security entitlement or securities account that is
included in the Collateral and (2) to exercise exclusive control over the Collateral.

 

(c)          Secured
Party will have the right, but no obligation, to exercise and enforce Debtor's rights and remedies with respect to the Collateral,
including, but not limited to, the right to demand, enforce payment of, collect and receive all dividends, interest, principal
payments and other sums that are at any time owing with respect to any of the Collateral and to apply the sums to the Indebtedness
in the manner that Secured Party reasonably determines.

 

    	 	-5-	 

     

    

 

(d)          Secured
Party may sell or otherwise dispose of the Collateral in a commercially reasonable manner. A notification that Secured Party is
required to give to Debtor regarding any sale or other disposition of Collateral will be considered reasonable if Secured Party
mails or otherwise sends or delivers it to Debtor at least ten (10) days before the sale or other disposition.

 

(e)          Secured
Party will apply the proceeds of a collection or disposition of Collateral first to Secured Party's attorney fees and expenses,
as provided in Paragraph 8 of this Agreement, and then to the Indebtedness, in the manner that Secured Party determines,
and Debtor will be liable for any deficiency remaining.

 

All rights and remedies of
Secured Party are cumulative and may be exercised from time to time.

 

9.          Expenses.
Debtor must reimburse Secured Party on demand for all attorney fees and other expenses that Secured Party incurs in preparing and
perfecting (subject to the $25,000 limitation in the Note), and protecting and enforcing Secured Party's rights under this Agreement.
This includes fees and expenses incurred in trying to obtain possession of Collateral from Debtor, a trustee or receiver in bankruptcy
or another person. Secured Party may apply proceeds of collection or disposition of Collateral to Secured Party's reasonable attorney
fees and other expenses.

 

10.         Amendments
and Waivers. A provision of this Agreement may not be modified or waived except by a written agreement signed by Secured Party
and Debtor. Secured Party will continue to have all of Secured Party's rights under this Agreement even if Secured Party does not
fully and promptly exercise them on all occasions. Debtor waives all defenses based on suretyship or impairment of collateral.
Without limiting the generality of the preceding sentence, (a) Secured Party may, at Secured Party's option, waive a default, defer
an action on a default; extend or modify the time or manner of payment of the Indebtedness or waive or modify a term or condition
relating to the Indebtedness; release Collateral or other security for the Indebtedness; release anyone that is liable for the
Indebtedness, including Debtor or a Guarantor; or make advances or other extensions of credit secured by this Agreement; all without
giving Debtor notice or obtaining Debtor's consent; and any of those actions by Secured Party shall not release or impair Secured
Party's security interest in the Collateral or Debtor's obligations under this Agreement, (b) Secured Party's security interest
in the Collateral and Debtor's obligations under this Agreement will not be released or impaired if Secured Party fails to obtain,
perfect or secure priority of, other security for the Indebtedness that anyone else gives or agrees to give and (c) Secured Party
is not required to sue upon or otherwise enforce payment of the Indebtedness or other security before exercising Secured Party's
rights under this Agreement.

11.         Notices.
A notice to Debtor or Secured Party will be considered to have been given if and when it is mailed, with postage prepaid, to the
address of Debtor or Secured Party on the first page of this Agreement or if and when it is delivered personally.

 

12.         Terminology;
Conflicts. Capitalized terms that are not otherwise defined in this Agreement shall have the meanings set forth in the
Note. Other terms used in this Agreement shall have the meanings set forth in the Uniform Commercial Code as in effect in the State
of Michigan on the date of this Agreement. In the event of a conflict between the terms of this Agreement
and the Note, the terms of the Note will control. 

 

13.         Binding
Effect. This Agreement will be binding upon and inure to the benefit of Debtor and Secured Party and their successors and assigns.

 

14.         Termination.
Upon the payment in full and termination of the Note and the Security Documents, this Agreement shall terminate and Secured
Party shall execute, acknowledge and deliver to Debtor an instrument in writing, prepared by Debtor, in recordable
form releasing its liens and security interests in the Collateral under this Agreement.

SECURITY AGREEMENT

(XG Sciences IP, LLC)

 

THIS SECURITY AGREEMENT
(“Agreement”) is made as of __________, 2016, by and between XG Sciences IP, LLC, a Michigan limited liability
company, of 3101 Grand Oak Drive, Lansing, Michigan 48911 (“Obligor”), and The Dow Chemical Company, of 2030
Dow Center, Midland, Michigan 48674 (“Secured Party”), for itself and as agent for the benefit of all other
affiliates of Secured Party (each, an “Affiliate”). Obligor is a wholly-owned subsidiary of XG Sciences, Inc.,
a Michigan corporation (“Borrower”). Borrower has entered into a certain Draw Loan Note and Agreement (as amended,
supplemented, restated or otherwise modified from time to time, “Note”) dated as of the date of this Agreement,
between Borrower and Secured Party. This Agreement is a condition to the terms of the Note.

 

1.          Grant
of Security Interest. Obligor grants to Secured Party a continuing security interest in all business assets of Obligor, including
without limitation:

 

(a)          all
machinery and equipment (including vehicles) and fixtures, wherever located, whether now owned or hereafter acquired by Obligor,
and all chattel paper evidencing any past, present or future leasing of the machinery, equipment or fixtures;

 

(b)          all
inventory, wherever located, whether now owned or hereafter acquired by Obligor; and any and all bills of lading, warehouse receipts
and other documents of title evidencing inventory; all rights of stoppage in transit of inventory; all chattel paper evidencing
any past, present or future leasing of inventory; and all letter of credit rights under all existing and future letters of credit
securing all or part of the purchase price of inventory that has been or is in the future sold by Obligor;

 

(c)          all
accounts, contract rights, chattel paper, instruments, investment property, general intangibles and letter of credit rights, wherever
located, whether now owned or hereafter acquired by Obligor;

 

(d)          all
deposit accounts, wherever located, whether now owned or hereafter acquired by Obligor;

 

(e)          all
trademarks, trade names, corporate names, business names, domain names, trade styles, trade dress, service marks, logos, source
identifiers, business identifiers, or designs of like nature now held or hereafter acquired by Obligor, any registration or recording
of the foregoing or any thereof, and any application in connection therewith, including without limitation, any such registration,
recording or application in the United States Patent and Trademark Office (“U.S. PTO”) or in any similar office
or agency of the United States, any state thereof or any country or political subdivision of such other country, and all extensions
or renewals of any of the foregoing;

 

     

     

    

  

(f)          any
letters patent of the United States or any country in which Obligor now or hereafter has title, all reissues, divisionals, continuations,
continuations-in-part, and extensions thereof, as well as any application for a letters patent in the United States or any other
country now or hereafter owned by Obligor, and all extensions or renewals of any of the foregoing;

 

(g)          any
copyright, copyrightable work, any registration or recording of any copyright or any copyrightable work to which Obligor now or
hereafter has title, and any application in connection with any copyright or copyrightable work owned by Obligor, including without
limitation, any such registration, recording or application in the United States Copyright Office or in any similar office or agency
of the United States, any state thereof, or any other country, and any renewal of any of the foregoing;

 

(h)          all
know-how, trade secrets, and business information, whether now owned or hereafter acquired by Obligor;

 

(i)          all
rights in computer programs and software applications and source codes of Obligor and all other proprietary information of Obligor;

 

together with (i) all proceeds of
the foregoing, including, without limitation, all cash, checks, drafts, accounts receivable, chattel paper, leases and instruments
received by Obligor in connection with any sale, lease, exchange or other disposition of any of the foregoing, and (ii) all
books, records (including computer software), and documents at any time evidencing or relating to any of the foregoing or any proceeds
thereof. All of the foregoing properties and assets of Obligor are referred to collectively in this Agreement as the “Collateral.”
Notwithstanding anything contained herein to the contrary, the term “Collateral” does not and shall not include
any patent rights within the meaning of that certain Restated and Amended Exclusive License Agreement between Michigan State University
and Borrower.

 

2.          Indebtedness
Secured. The foregoing security interest is given to secure payment and performance of ALL OBLIGATIONS AND INDEBTEDNESS THAT
EITHER OBLIGOR OR BORROWER NOW AND IN THE FUTURE OWES TO SECURED PARTY AND ANY AFFILIATE under this Agreement, and all obligations
and indebtedness of Borrower to Secured Party under the Note, as well as all obligations and indebtedness of either Obligor or
Borrower under all other security agreements, pledge agreements, assignments, mortgages, guaranties, notes, loan agreements, and
other agreements, instruments and documents that either Obligor or Borrower has signed or in the future signs related thereto,
and all extensions and renewals of such indebtedness and obligations.

 

The indebtedness and obligations that this
Agreement secures are collectively called the “Indebtedness.”

 

3.          Warranties,
Representations, and Agreements. Obligor warrants and represents to Secured Party, and agrees, as follows:

 

    2 

     

    

  

(a)          Obligor
is the owner of the Collateral, and none of the Collateral is subject to a lien, security interest, encumbrance or claim in favor
of a third party (other than Borrower), and no financing statement is on file in a public office covering any of the Collateral,
except in favor of Secured Party or with respect to Permitted Liens.

 

(b)          Obligor
has full power and authority to enter into and perform its obligations under this Agreement.

 

(c)          This
Agreement is the valid and binding obligation of Obligor and is enforceable against Obligor in accordance with its terms.

 

(d)          All
information that Obligor has furnished or in the future furnishes to Secured Party concerning the Collateral, including, without
limitation, all information concerning the condition, and quality of the Collateral, is and will be correct and complete.

 

(e)          Obligor’s
exact legal name is set forth in the first paragraph of this Agreement.

 

(f)          Obligor’s
address set forth on the first page of this Agreement is the location of Obligor’s chief executive office.

 

(g)          Any
part of the Collateral that consists of accounts or chattel paper does and shall evidence bona fide sales or leases to the parties
named in Obligor’s books, and Obligor is not aware of any existing defense to any account or chattel paper.

 

(h)          Exhibit
A to this Agreement contains a complete and accurate list of all of Obligor’s and Borrower's United States intellectual
property registrations, recordings and applications. Obligor shall provide Secured Party with an updated Exhibit A (1) within thirty
(30) days after the date of this Agreement to list international intellectual property registrations, recordings and applications,
and (2) from time to time for any additions or deletions to such list occurring after the date of this Agreement. Except as disclosed
on Exhibit A and except for business information, know-how and trade secrets, there is no intellectual property that is material
to Obligor or Borrower.

 

(i)          Each
current employee of Obligor is bound by a nondisclosure agreement in form and substance previously disclosed to Secured Party.

 

4.          Agreements
of Obligor. Obligor agrees that:

 

(a)          Obligor
shall not cause or permit any lien, security interest or encumbrance to be placed on any Collateral (other than Permitted Liens),
except in favor of Secured Party and Obligor shall not sell, assign or transfer any Collateral or permit any Collateral to be transferred
by operation of law, except for intellectual property licensed to Borrower, as permitted under the Note and sales of inventory
in the ordinary course of Obligor’s business. A sale in the ordinary course of business does not include a transfer in partial
or complete satisfaction of a debt.

 

    3 

     

    

  

(b)          Obligor
shall maintain all records concerning the Collateral at Obligor’s chief executive office.

 

(c)          Obligor
shall furnish to Secured Party all information regarding the Collateral that Secured Party from time to time reasonably requests
and shall allow Secured Party at any reasonable time to inspect the Collateral and Obligor’s records regarding the Collateral.

 

(d)          Obligor
shall sign, file, record or obtain from third persons all subordination agreements and other documents, and shall take all other
actions, that Secured Party reasonably considers necessary or appropriate to perfect, to continue perfection of, or to maintain
first priority (except with respect to Permitted Liens) of, Secured Party’s security interest in the Collateral and
Obligor shall place upon the Collateral and/or documents evidencing the Collateral any notice of Secured Party’s security
interest that Secured Party from time to time reasonably requires. Actions that Secured Party may require Obligor to
take under the preceding sentence include, without limitation, (1) obtaining from any third party who has possession of Collateral
an acknowledgment that the third party holds the Collateral for Secured Party and (2) obtaining agreements from banks, securities
intermediaries, issuers of letters of credit and others, and taking all other actions reasonably requested by Secured Party, to
give Secured Party control of any part of the Collateral consisting of investment property, deposit accounts, letter of credit
rights or electronic chattel paper.

 

(e)          Obligor
shall immediately notify Secured Party in writing of any change in Obligor’s name, identity or organizational structure,
and of any change in the location of Obligor’s place of business and of the location of each additional place of business
that Obligor establishes. Obligor shall not make a change in its name or its organizational structure or in the jurisdiction under
the laws of which Obligor is organized, without Secured Party’s prior written consent.

 

(f)          Obligor
shall indemnify Secured Party with respect to all losses, damages, liabilities and expenses (including attorney fees) that Secured
Party incurs by reason of a failure of Obligor to comply with an obligation under this Agreement or by reason of a warranty or
representation that Obligor makes to Secured Party in this Agreement being false in any material respect.

 

(g)          After
the occurrence of an Event of Default (subject to applicable cure periods), Obligor shall take all steps reasonably necessary to
permit Secured Party to contact its account Obligors at any time for the purpose of verifying the existence, amount and collectability
of, and other information regarding, Obligor’s accounts, chattel paper, instruments or general intangibles.

 

    4 

     

    

  

(h)          Obligor
shall maintain all tangible Collateral in good condition and repair and maintain special form, replacement cost property insurance
covering all tangible Collateral. As soon after closing as reasonably practicable, but no later than 30 days after closing,
each insurance policy (1) shall provide that its proceeds shall be payable to Secured Party to the extent of Secured Party's
interest in the Collateral, (2) shall contain a standard lender's loss payable endorsement in favor of Secured Party, (3) shall
provide that the policy shall not be canceled, and the coverage shall not be reduced, without at least 10 days' prior written notice
by the insurer to Secured Party and (4) shall otherwise be in form and substance satisfactory to Secured Party. Obligor shall provide
Secured Party evidence of that insurance coverage. Upon Secured Party's request, Obligor shall deliver to Secured Party all policies
that provide for such insurance. Obligor agrees that Secured Party may act as agent for Obligor in obtaining, adjusting, and settling
that insurance and endorsing any draft evidencing proceeds of it.

 

(i)          To
the extent that applicable law at any time permits a secured party to file a financing statement that is not authenticated by Obligor,
Obligor authorizes Secured Party to file one or more financing statements containing an indication that such financing statement
covers the Collateral. The financing statements that Secured Party files to perfect its security interest in the Collateral may
describe the Collateral as “all assets” or “all personal property” that Obligor now owns or acquires in
the future. If Secured Party has previously filed one or more financing statements to perfect its security interest in the Collateral,
then Obligor approves and ratifies those filings.

 

(j)          Obligor
shall pay, before they become delinquent, all taxes and assessments upon the Collateral or for its use or operation and pay and
perform when due all indebtedness and obligations under all leases, land contracts or other agreements under which Obligor has
possession of any real property upon which any of the Collateral is at any time located and under any mortgage or mortgages at
any time covering that real property.

 

(k)          Obligor
shall prepare, execute, acknowledge and deliver to Secured Party an instrument in writing in recordable form for recording a lien
on and security interest in and to all of its right, title and interest in, to and under all new patent and trademark application
filings and any rights extending therefrom, either in the United States or any other country and all proceeds of any and all of
the foregoing, within one month after the filing of any such applications.

 

(l)          Obligor
shall timely enter into a nondisclosure agreement, in form and substance reasonably acceptable to Secured Party, with each new
employee, manager, director, and officer of Obligor, and all agents and other parties to whom trade secrets or other confidential
information of Obligor or any affiliate of Obligor may be disclosed.

 

(m)          Obligor
shall not commit any material breach or default under that certain license agreement between Obligor and Michigan State University
dated as of July 27, 2007 and amended on May 24, 2010 and May 27, 2011, as it may be amended, restated, renewed, extended, replaced,
or modified.

 

    5 

     

    

  

5.          Secured
Party’s Right to Perform. If Obligor fails to perform an obligation of Obligor under this Agreement, then Secured Party
may, without giving notice to or obtaining the consent of Obligor, perform that obligation on behalf of Obligor. Obligor shall
reimburse Secured Party on demand for any expense that Secured Party incurs in performing the obligation and shall pay to Secured
Party interest on each expense, from the date the expense was incurred by Secured Party, at 5% per annum (“Default Rate”).
Secured Party is not required to perform an obligation that Obligor has failed to perform. If Secured Party does so, then that
shall not be a waiver of Secured Party’s right to declare the Indebtedness immediately due and payable by reason of Obligor’s
failure to perform.

 

6.          Events
of Default and Acceleration. Any part or all of the Indebtedness shall, at the option of Secured Party, become immediately
due and payable without notice or demand upon the occurrence of any of the following events of default (each, an “Event
of Default”):

 

(a)          If
an Event of Default occurs under and as defined in the Note, including any default occurs in the payment or performance of any
of the Indebtedness, when and as it is due and payable subject to applicable grace periods.

 

(b)          If
Debtor fails to perform any other material obligation, covenant or agreement of Obligor or Borrower to Secured Party under this
Agreement, under a promissory note or other instrument that at any time evidences any Indebtedness or under any other security
agreement, loan agreement, mortgage, assignment, guaranty or other agreement that now or in the future secures or relates to any
Indebtedness (“Security Documents”).

 

(c)          If
a warranty, representation, or statement that has been or in the future is made to Secured Party by Obligor, Borrower or by a guarantor
of all or part of the Indebtedness (“Guarantor”) in this Agreement or in a Security Document shall have been
false in any material respect when made or furnished.

 

(d)          If
Obligor, Borrower or a Guarantor dissolves, becomes insolvent or makes an assignment for the benefit of creditors.

 

(e)          If
a guaranty that now or in the future secures payment or performance of all or a part of the Indebtedness is terminated, revoked
or limited for any reason, without Secured Party’s written consent or agreement.

 

(f)          If
an attachment, garnishment, levy, execution or other legal process is at any time issued against or placed upon any of the Collateral
(other than with respect to Permitted Liens) and is not terminated or released within 30 days.

 

(g)          If
all or a substantial part of the tangible Collateral is destroyed or materially damaged by fire or other casualty, and cannot be
repaired or replaced within a commercially reasonable time, not to exceed 90 days, whether or not there is insurance coverage for
the damage or destruction.

 

If an Event of Default is capable
of being cured, then Obligor may cure the same during the thirty-day period that begins on the date on which Obligor receives notice
from Secured Party, or otherwise has actual knowledge, of the event (the “Cure Period”). An Event of Default
that is capable of being cured will not be deemed to have occurred as a result of an event during the Cure Period for that event
or, if the event is cured during the Cure Period, thereafter. 

 

    6 

     

    

  

If a voluntary or involuntary case in bankruptcy,
receivership or insolvency is at any time begun by or against Obligor, Borrower or a Guarantor or if any attachment, garnishment,
levy, execution or other legal process is at any time issued against or placed upon Collateral and not terminated or released within
30 days, then the entire Indebtedness shall automatically become immediately due and payable, without notice or demand. All or
part of the Indebtedness also may become, or may be declared to be, immediately due and payable under the terms of the Note or
a note that at any time evidences any Indebtedness or under a Security Document that has been or in the future is entered into
between Obligor and Secured Party.

 

7.          Secured
Party’s Rights and Remedies. Secured Party shall have all rights and remedies of a secured party under applicable laws.
Without limiting those rights and remedies, upon the occurrence of an Event of Default (subject to applicable cure periods):

 

(a)          (1)
Without notice or demand to Obligor, Secured Party shall be entitled to notify Obligor’s account debtors and obligors to
make all payments directly to Secured Party, and Secured Party shall have the right to take all actions that Secured Party reasonably
considers necessary or desirable to collect upon the Collateral, including, without limitation, prosecuting actions against, or
settling or compromising disputes and claims with, Obligor’s account debtors and obligors, (2) without notice or demand
to Obligor, Secured Party may receive, open, dispose of and notify the postal authorities to change the address of, mail directed
to Obligor, and (3) upon Secured Party’s demand, Obligor shall immediately deliver to Secured Party, at the place that
Secured Party designates, all proceeds of the Collateral and all books, records, agreements, leases, documents and instruments
that evidence or relate to the Collateral.

 

(b)          Obligor,
upon Secured Party’s demand, shall assemble the Collateral and proceeds of Collateral at Debtor’s place of business,
and Secured Party may dispose of the Collateral in any commercially reasonable manner. Any notification that Secured Party is required
to give to Obligor regarding sale or other disposition of Collateral shall be considered reasonable if it is mailed at least 10
days before the sale or other disposition. In connection with a disposition of Collateral, Secured Party may comply with the requirements
of an applicable state or federal law or regulation, and such compliance shall not cause the disposition to not be commercially
reasonable.

 

(c)          Secured
Party shall have the right (but no obligation) to continue or complete the manufacturing or processing of, or other operations
in connection with, any part of the Collateral, and, for that purpose, to enter and remain upon or in any land or buildings
that are possessed by Obligor or that Obligor has the right to possess. Obligor shall reimburse Secured Party on demand for any
net expense that Secured Party incurs in connection with those activities and shall pay to Secured Party interest on each net expense,
from the date on which Secured Party incurred the expense, at the Default Rate.

 

    7 

     

    

  

The proceeds of any collection or disposition
of Collateral shall be applied first to Secured Party's attorney fees and expenses, as provided in Paragraph 8 of this Agreement,
then to the unpaid interest accrued on the Indebtedness and then to the principal of the Indebtedness, and Obligor shall be liable
for any deficiency. Secured Party does not have any obligation to prepare or process any Collateral for sale or other disposition.
If Secured Party sells any of the Collateral on credit, then Obligor will be credited only with payments that the purchaser actually
makes and that Secured Party receives and applies to the unpaid balance of the purchase price of the Collateral. If the purchaser
fails to pay for the Collateral, then Secured Party may again dispose of the Collateral and apply the proceeds in accordance with
this paragraph. All rights and remedies of Secured Party under this Agreement, whether or not exercisable only on default, shall
be cumulative and may be exercised from time to time. No delay by Secured Party in the exercise of any right or remedy shall operate
as a waiver thereof, and no single or partial exercise of any right or remedy shall preclude other or further exercise thereof
or the exercise of any other right or remedy.

 

8.          Expenses.
Obligor shall reimburse Secured Party on demand for all reasonable attorney fees, legal expenses, and other expenses that Secured
Party incurs in perfecting (subject to the $25,000 limitation in the Note), protecting and enforcing its interest in the Collateral
and its rights under this Agreement. This includes fees and expenses incurred in trying to take possession of Collateral from Obligor,
a trustee or receiver in bankruptcy, or any other person. Secured Party may apply any proceeds of collection or disposition of
Collateral to Secured Party's attorney fees, legal expenses and other out-of-pocket expenses.

 

9.          Amendments
and Waivers. No provision of this Agreement may be modified or waived except by a written agreement signed by Secured
Party and Obligor. Secured Party will continue to have all of its rights under this Agreement even if it does not fully and
promptly exercise them on all occasions. Secured Party may, at its option: waive any default; defer an action on any default; extend
or modify the time or manner of payment of the Indebtedness or waive or modify any term or condition relating to the Indebtedness;
release Collateral or other security for the Indebtedness; release any person liable for any of the Indebtedness, including Obligor;
or make advances or other extensions of credit secured hereby; all without giving Obligor notice or obtaining Obligor's consent.
Any such action by Secured Party will not release or impair its security interest in the Collateral or Obligor's obligations
under this Agreement. Secured Party's security interest in the Collateral and Obligor's obligations under this Agreement will not
be released or impaired if Secured Party fails to obtain, perfect, or secure priority of any other security for the Indebtedness
that is agreed to be given, or is given, by anyone else. Secured Party is not required to sue upon or otherwise enforce payment
of the Indebtedness or any other security before exercising its rights under this Agreement.

 

10.         Notices.
Any notices or communications required or permitted under this Agreement shall be governed by the Note.

 

11.         Terminology;
Conflicts. Capitalized terms that are not otherwise defined in this Agreement shall have the meanings set forth in the Note.
Other terms used in this Agreement shall have the meanings set forth in the Uniform Commercial Code as in effect in the State of
Michigan on the date of this Agreement. In the event of a conflict between the terms of this Agreement and the Note, the terms
of the Note will control.

 

    8 

     

    

  

12.         Binding
Effect. This Agreement shall be binding upon and inure to the benefit of Obligor and Secured Party and their respective successors
and assigns. This Agreement is provided to Secured Party as an inducement to Secured Party to make the loans to Borrower that are
contemplated by the Note, and in consideration of the loans by Secured Party to Borrower pursuant to the Note, and for other good
and valuable consideration. Obligor derives substantial benefit from the loans to Borrower under the Note.

 

13.         Termination.
Upon the payment in full and termination of the Note and the Security Documents, this Agreement shall terminate and Secured Party
shall execute, acknowledge and deliver to Obligor an instrument in writing, prepared by Debtor, in recordable form releasing its
liens and security interests in the Collateral under this Agreement.

 

SECURED PARTY AND
OBLIGOR EACH IRREVOCABLY AND UNCONDITIONALLY WAIVES ITS RIGHT TO A TRIAL BY JURY IN ANY ACTION, INCLUDING A CLAIM, COUNTERCLAIM,

Exhibit A

 

List of Intellectual Property

 

Michigan State University License

 

We have acquired an exclusive license for a number of
inventions from Michigan State University. These rights are embodied in a Technology Licensing Agreement between XGS and
Michigan State University dated July 27, 2007 and amended on May 24, 2010 and May 27, 2011, which owns the rights to all
intellectual property resulting from research performed at the University. This Agreement gives us the exclusive worldwide
rights to the subject intellectual property in its field. In exchange for the rights to the technology covered by this
Agreement, we paid MSU an initial fee and agreed to pay ongoing royalties on the basis of material sold by us in future
years. Under a previous version of the Licensing Agreement, we also awarded a small amount of common stock to MSU. The
intellectual property covered by the Agreement is in various stages of development and legal protection. Because there is an
active research program underway in this area, we also anticipate that we may add other MSU inventions to our Agreement. In
some limited cases, depending on the source of research funds, other parties may have limited rights to use the inventions
covered by these agreements. This is typical in the case of research funded by U.S. government agencies and is sometimes the
case when research has been funded or partially funded by private corporations.

 

As of November 1, 2016 the following technologies were included
in the MSU License Agreements with XGS and were being actively prosecuted at the U.S. Patent Office:

 

		·	U.S. Patent Application No. 12/587,645. “Electrically Conductive, Optically Transparent Films of Exfoliated Graphite
NanoParticles & Methods of Making the Same”

 

		·	U.S. Patent Application No. 13/199,086. “PI Coupling Agents for Dispersion of Graphene NanoPlatelets in Polymers”,

COMMON STOCK PURCHASE
WARRANT

 

	Certificate No: __________	Warrants to Purchase
	 	________ Shares of Common Stock
	 	December __, 2016

 

This Common Stock Purchase Warrant (this
"Warrant") certifies that, for value received, The Dow Chemical Company or its registered assignees
(the "Holder") is entitled, upon the terms and subject to the limitations on exercise and the conditions hereinafter
set forth, at any time on or after the date hereof (the "Initial Exercise Date") and on or prior to 5:00 PM Eastern
Time on December __, 2023, (the "Expiration Date") but not thereafter, to purchase from XG Sciences, Inc.,
a Michigan corporation with offices at 3101 Grand Oak Dr., Lansing, MI 48911 (the "Company"), up to ___________
shares (the "Shares" and each, a "Share") of the Company's common stock, no par value per share
(the "Common Stock"), at a price of $______ per Share, as adjusted in accordance with Section 4 below (the "Purchase
Price").

 

This Warrant is issued in connection with
the Draw Loan Note and Agreement, dated as of December 7, 2016, by and among the Company, and Holder (the "Note
Agreement"). Certain capitalized terms used herein that are not otherwise defined herein shall have the meanings set forth
in the Note Agreement.

 

Section 1.          Exercise
of Warrants.

 

(a)          Upon
presentation and surrender at the principal executive office of the Company of this Warrant prior to the Expiration Date together
with a check to the Company in the amount of the Purchase Price multiplied by the number of Shares of Common Stock being purchased,
and compliance with the other requirements of Section 1(e) and this Warrant, the Company will issue to the Holder, Shares of Common
Stock which in the aggregate represent the number of Shares of Common Stock being purchased. This Warrant may be partially exercised
and, in the case of such partial exercise, the Company, upon surrender hereof, will deliver to the Holder a new Warrant representing
the number of Shares which have not been exercised.

 

     

     

    

 

(b)          In
lieu of exercising this Warrant, the Holder may elect to receive Shares equal to the value of this Warrant (or the portion thereof
being canceled) by surrender of this Warrant at the principal office of the Company along with the other documents required by
Section 1(e) and compliance with the requirements of this Warrant, in which event the Company shall issue to the Holder a number
of Shares computed using the following formula:

 

	 	Y (A-B)
	X = 	 
	 	A

 

"X"equals
the number of Shares to be issued to the Holder.

 

"Y"equals
the number of Shares purchasable under this Warrant.

 

"A"equals
the fair market value of one Share on the date of determination.

 

"B"equals
the per share Purchase Price (as adjusted to the date of such calculation).

 

(c)          Fair
Market Value. For purposes of this Section 1, the per share fair market value of the Shares means:

 

(i)          If
the Common Stock is publicly traded, the per share fair market value of the Shares shall be (a) the daily volume weighted average
price of the Common Stock for such date (or the nearest preceding date) on the trading market (including, without limitation, the
OTCQX and OTCQB markets maintained by the OTC Markets Group, Inc. and any successor-entities) which the Common Stock is then listed
or quoted as reported by Bloomberg L.P. (based on a trading day from 9:30 a.m. (New York City time) to 4:02 p.m. (New York City
time)), (b) if the OTC Bulletin Board is not a trading market, the volume weighted average price of the Common Stock for such date
(or the nearest preceding date) on the OTC Bulletin Board, (c) if the Common Stock is not then listed or quoted for trading on
the OTC Bulletin Board and if prices for the Common Stock are then reported in the "Pink Sheets" published by Pink OTC
Markets, Inc. (or a similar organization or agency succeeding to its functions of reporting prices), the most recent bid price
per share of the Common Stock so reported; or

 

(i)          If
the Common Stock is not so publicly traded, the per share fair market value of the Shares shall be such fair market value as is
determined in good faith by the Board of Directors of the Company after taking into consideration factors it deems appropriate,
including, without limitation, recent sale and offer prices of the capital stock of the Company in private transactions negotiated
at arm's length.

 

    	 	2	 

     

    

 

(d)          If
this Warrant shall be deemed "in the money" on the Expiration Date and the Holder has not exercised his, her or its rights
hereunder, the Company shall automatically effect a cashless exercise of this Warrant on behalf of the Holder in accordance with
the formula hereinabove, provided that the Holder must promptly thereafter comply with the other requirements of Section 1(e) and
this Warrant.

 

(e)          The
rights represented by this Warrant may be exercised by the Holder, in whole or in part (with respect to Shares of Common Stock),
subject to the conditions contained herein and at any time prior to the Expiration Date, by: (i) surrender of this Warrant for
cancellation at the principal executive office of the Company (or at such other office or agency of the Company as it may designate
by notice in writing to the Holder at the address of the Holder appearing on the books of the Company); (ii) payment to the Company
of the Purchase Price for the number of Shares of Common Stock specified in the Notice of Exercise form; (iii) delivery to the
Company of a duly executed agreement signed by the person(s) designated in the Notice of Exercise form to the effect that such
person(s) agree(s) to be bound by all of the terms and conditions of this Warrant; (iv) delivery to the Company of a duly executed
Notice of Exercise form attached hereto as Exhibit A and Investment Representation Statement form attached hereto as Exhibit
D to the extent such Investment Representation Statement remains applicable; and (v) delivery to the Company of duly executed
adoption agreements for the Shareholder Agreement and the Voting Agreement (each as defined in Section 2(b)) as and to the extent
required by Section 8(g). This Warrant shall be deemed to have been exercised, in whole or in part to the extent specified, immediately
prior to the close of business on the date on which all of the applicable provisions of this Section 1(e) are reasonably satisfied,
and the person(s) designated in the Notice of Exercise form shall become the holder(s) of record of the Shares of Common Stock
issuable upon such exercise at that time and date.

 

(f)          As
soon as possible after any full or partial exercise of this Warrant, but in any event no more than ten (10) business days, the
Company, at its expense, will instruct its transfer agent to issue as soon as possible in the name of and delivered to the Holder
of this Warrant, the number of fully paid and non-assessable Shares of Common Stock to which that Holder shall be entitled on such
exercise. No fractional shares will be issued on exercise of this Warrant. If, on any exercise of this Warrant, a fractional share
results, the Company will pay the cash value of that fractional share, calculated on the basis of the Purchase Price. The Company
may issue certificates for Shares or, if consistent with the Company’s generally applicable practice, may issue uncertificated
Shares as permitted under the Michigan Business Corporation Act. Any certificates evidencing the Shares shall bear restrictive
legends to the extent required by this Warrant.

 

Section 2.          Legends.

 

(a)          Until
the date on which a registration statement filed by the Company under the Securities Act of 1933, as amended (the "Securities
Act") covering the issuance and sale or the resale of the Shares is declared effective by the U.S. Securities and Exchange
Commission (the "SEC"), any certificates evidencing the Shares shall bear a legend substantially in the following
form:

 

    	 	3	 

     

    

 

"These
securities have not been registered under the Securities Act of 1933, as amended, or registered or qualified under applicable state
securities laws and may not be offered for resale or resold unless registered pursuant to the provisions of the securities act
and registered or qualified pursuant to the provisions of applicable state securities laws, unless an exemption from such registration
or qualification is available."

 

(b)          Any
certificates evidencing the Shares shall bear legends to the extent required by the Company’s shareholder agreement dated
March 18, 2013 and amended effective as of April 13, 2016 (the “Shareholder Agreement”) and the Company’s
voting agreement dated January 15, 2014 (the “Voting Agreement”).

 

(c)          Any
certificates evidencing the Shares shall bear legends substantially in the following form to the extent reasonably required by
the Company:

 

“The
shares of stock represented by this certificate are subject to agreements set forth in the Bylaws of the Corporation among the
shareholders of the Corporation pursuant to Section 488 of the Michigan Business Corporation Act. A copy of the Bylaws is on file
with the Secretary of the Corporation. By acceptance of this certificate, the holder hereof agrees to be bound by the terms of
said agreements.”

 

(d)          The
Holder consents to the Company making a notation on its records and giving instructions to any transfer agent in order to implement
the restrictions on transfer established in this Warrant (including in the foregoing contemplated legends), the Shareholder Agreement
or the Voting Agreement. The Company will not be required to (i) transfer on its books any securities that have been transferred
in violation of any provisions of this Warrant, the Shareholder Agreement, the Voting Agreement or applicable law, or (ii) to treat
as owner of such securities, or accord the right to vote or pay dividends to any purchaser, donee or other transferee to whom such
securities may have been so transferred.

 

Section 3.          Charges,
Taxes and Expenses. Issuance of Shares shall be made without charge to the Holder for any issue or transfer tax or other incidental
expense in respect of the issuance of such Shares, all of which expenses shall be paid by the Company, and such Shares shall be
issued in the name of the Holder or in such name or names as may be directed by the Holder; provided, however, that in the event
certificates for Shares are to be issued in a name other than the name of the Holder, this Warrant when surrendered for exercise
shall be accompanied by the Assignment Form attached hereto duly executed by the Holder, the assignee, and the Company may require,
as a condition thereto, the payment of a sum sufficient to reimburse it for any expenses incidental thereto.

 

    	 	4	 

     

    

 

Section 4.          Certain
Adjustments.

 

(a)          Stock
Dividends and Stock Splits. If the Company, at any time after the date hereof: (A) shall pay a stock dividend or otherwise
make a distribution or distributions on shares of its Common Stock in shares of Common Stock, (B) subdivide outstanding shares
of Common Stock into a larger number of shares, or (C) combine (including by way of reverse stock split) outstanding shares of
Common Stock into a smaller number of shares, then the Purchase Price shall be multiplied by a fraction of which the numerator
shall be the number of shares of Common Stock outstanding before such event and of which the denominator shall be the number of
shares of Common Stock outstanding after such event. Any adjustment made pursuant to this Section shall become effective immediately
after the record date for the determination of stockholders entitled to receive such dividend or distribution and shall become
effective immediately after the effective date in the case of a subdivision, combination or re-classification, and the number of
Shares issuable upon exercise of this Warrant shall be proportionately adjusted such that the aggregate Purchase Price of this
Warrant shall remain unchanged.

 

(b)          Fundamental
Transaction. If, at any time while this Warrant is outstanding, (A) the Company effects any merger or consolidation of the
Company with or into another person, (B) the Company effects any sale of all or substantially all of its assets in one or a series
of related transactions, (C) any tender offer or exchange offer (whether by the Company or another person) is completed pursuant
to which holders of Common Stock are permitted to tender or exchange their shares for other securities, cash or property, or (D)
the Company effects any reclassification of the Common Stock or any compulsory share exchange pursuant to which the Common Stock
is effectively converted into or exchanged for other securities, cash or property (in any such case, a "Fundamental Transaction"),
then upon any subsequent exercise of this Warrant, the Holder shall have the right to receive, for each Share of Common Stock that
would have been issuable upon such conversion absent such Fundamental Transaction, the same kind and amount of securities, cash
or property as it would have been entitled to receive upon the occurrence of such Fundamental Transaction if it had been, immediately
prior to such Fundamental Transaction, the holder of one share of Common Stock (the "Alternate Consideration").
For purposes of any such conversion, the determination of the Purchase Price shall be appropriately adjusted to apply to such Alternate
Consideration based on the amount of Alternate Consideration issuable in respect of one share of Common Stock in such Fundamental
Transaction, and the Company shall apportion the Purchase Price among the Alternate Consideration in a reasonable manner reflecting
the relative value of any different components of the Alternate Consideration. If holders of Common Stock are given any choice
as to the securities, cash or property to be received in a Fundamental Transaction, then the Holder shall be given the same choice
as to the Alternate Consideration it receives upon any exercise of this Warrant following such Fundamental Transaction. To the
extent necessary to effectuate the foregoing provisions, any successor to the Company or surviving entity in such Fundamental Transaction
shall issue to the Holder a new warrant consistent with the foregoing provisions and evidencing the Holder's right to exercise
such warrant for the Alternate Consideration. The terms of any agreement pursuant to which a Fundamental Transaction is effected
shall include terms requiring any such successor or surviving entity to comply with the provisions of this paragraph (b) and insuring
that this Warrant (or any such replacement security) will be similarly adjusted upon any subsequent transaction analogous to a
Fundamental Transaction.

Section 5.          Transfer
of Warrant. Subject to the requirements of this Warrant, compliance with the Securities Act and other federal and state law,
and the Company’s Articles of Incorporation and Bylaws, all rights hereunder are transferable, in whole or in part, upon
surrender of this Warrant at the principal executive office of the Company or its designated agent, together with a written assignment
of this Warrant substantially in the form attached hereto as Exhibit B and the Investment Representation Statement attached
hereto as Exhibit D to the extent such Investment Representation Statement remains applicable, duly executed by the Holder
or its agent or attorney and funds sufficient to pay any transfer taxes payable upon the making of such transfer. Upon such surrender
and, if required, such payment, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or
assignees, as applicable, and in the denomination or denominations specified in such instrument of assignment, and shall issue
to the assignor a new Warrant evidencing the portion of this Warrant not so assigned, and this Warrant shall promptly be cancelled.
The Warrant, if properly assigned in accordance herewith, may be exercised by a new holder for the purchase of Warrant Shares without
having a new Warrant issued.

 

Section 6.           Representations
and Warranties.

 

(a)          Common Stock.
The Company hereby represents and warrants to the Holder that all Shares that may be issued upon the exercise of the purchase rights
represented by this Warrant, and all securities, shall, upon issuance, be duly authorized, validly issued, fully paid and nonassessable,
and free of any liens and encumbrances. The Company hereby agrees that it shall at all times reserve and keep available out of
its authorized but unissued Common Stock, solely for the purpose of effecting the exercise of this Warrant, a number of shares
of Common Stock equal to the number of shares as shall from time to time be sufficient to effect the exercise of this entire Warrant
at the Purchase Price.

 

(b)          Notice of
Certain Events. If the Company proposes at any time (i) to declare any dividend or distribution upon its Common Stock, whether
in cash, property, stock, or other securities and whether or not a regular cash dividend; (ii) to offer for subscription pro rata
to the holders of any class or series of its stock any additional shares of stock of any class or series or other rights; (iii)
to effect any reclassification or recapitalization of Common Stock; (iv) to merge or consolidate with or into any other corporation,
or sell, lease, license, or convey all or substantially all of its assets, or to liquidate, dissolve or wind up, or to effect an
acquisition; or (v) to offer holders of registration rights the opportunity to participate in an underwritten public offering of
the company’s securities for cash, then, in connection with each such event, the Company shall give Holder (1) at least 20
days prior written notice of the date on which a record will be taken for such dividend, distribution, or subscription rights (and
specifying the date on which the holders of Common Stock will be entitled thereto) or for determining rights to vote, if any, in
respect of the matters referred to in (i) and (ii) above; (2) in the case of the matters referred to in (iii) and (iv) above at
least 20 days prior written notice of the date when the same will take place (and specifying the date on which the holders of Common
Stock will be entitled to exchange their Common Stock for securities or other property deliverable upon the occurrence of such
event); and (3) in the case of the matter referred to in (v) above, the same notice as is given to the holders of such registration
rights.

 

    	 	6	 

     

    

 

(c)          Investment
Representation Statement. The Holder hereby makes to the Company each of the representations and warranties in the Investment
Representation Statement form attached hereto as Exhibit D.

 

Section 7.          Indemnification.
Without limitation of any other provision of this Warrant or any other agreement between the Holder and the Company, the Company
agrees to defend, indemnify and hold Holder, its respective affiliates and direct and indirect partners (including partners of
partners and stockholders and members of partners), members, stockholders, directors, officers, employees and agents and each person
who controls any of them within the meaning of Section 15 of the Securities Act, or Section 20 of the Securities Exchange Act of
1934, as amended (the "Exchange Act") (collectively, the "Holder Indemnified Parties" and, individually,
a "Holder Indemnified Party") harmless from and against any and all damages, liabilities, losses, taxes, fines,
penalties, reasonable costs and expenses (including, without limitation, reasonable fees of a single counsel representing the Holder
Indemnified Parties), as the same are incurred, of any kind or nature whatsoever (whether or not arising out of third-party claims
and including all amounts paid in investigation, defense or settlement of the foregoing) which may be sustained or suffered by
any such Holder Indemnified Party ("Losses"), based upon, arising out of, or by reason of (a) any breach of any
representation or warranty made by the Company in this Warrant, the Note Agreement, or any other agreement executed in connection
herewith, (b) any breach of any covenant or agreement made by the Company in this Warrant, the Note Agreement, or any other agreement
executed in connection herewith, or (c) any third party or governmental claims relating in any way to such Holder Indemnified
Party’s status as a security holder, creditor, director, agent, representative or controlling person of the Company or otherwise
relating to such Holder Indemnified Party’s involvement with the Company (including, without limitation, any and all Losses
under the Securities Act, the Exchange Act or other federal or state statutory law or regulation, at common law or otherwise, which
relate directly or indirectly to the registration, purchase, sale or ownership of any securities of the Company or to any fiduciary
obligation owed with respect thereto), including, without limitation, in connection with any third party or governmental action
or claim relating to any action taken or omitted to be taken or alleged to have been taken or omitted to have been taken by any
Holder Indemnified Party as security holder, director, agent, representative or controlling person of the Company or otherwise,
alleging so-called control person liability or securities law liability. The term "Losses" shall specifically
exclude loss of profits and all punitive, incidental, consequential, special or indirect damages, except to the extent paid to
a third party, and shall include diminution of value. The rights of the parties hereunder shall be in addition to, and not in lieu
of, any other rights and remedies which may be available to it by law; provided, however, that the Company will not
be liable to the extent that such Losses arise from and are based on conduct by a Holder Indemnified Party that constitutes fraud,
gross negligence or willful misconduct.

 

Section 8.          Miscellaneous.

 

(a)          No
Rights as Stockholder Until Exercise. This Warrant does not entitle the Holder to any voting rights, dividends or other rights
as a stockholder of the Company prior to the exercise hereof.

 

    	 	7	 

     

    

 

(b)          Loss,
Theft, Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company of evidence reasonably
satisfactory to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the Shares,
and in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (which, in the case of the Warrant,
shall not include the posting of any bond), and upon surrender and cancellation of such Warrant or stock certificate, if mutilated,
the Company will make and deliver a new Warrant or stock certificate of like tenor and dated as of such cancellation, in lieu of
such Warrant or stock certificate.

 

(c)          Saturdays,
Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required or
granted herein shall not be a business day (because it is a Saturday, Sunday or U.S. federal holiday), then such action may be
taken or such right may be exercised on the next succeeding business day.

 

(d)          Authorized
Shares. The Company covenants that, during the period the Warrant is outstanding, it will reserve from its authorized and unissued
Common Stock a sufficient number of shares of Common Stock to provide for the issuance of the Shares upon the exercise of any purchase
rights under this Warrant. The Company further covenants that its issuance of this Warrant shall constitute full authority to its
officers who are charged with the duty of executing stock certificates to execute and issue the necessary certificates for the
Shares upon the exercise of the purchase rights under this Warrant. The Company will take all such reasonable action as may be
necessary to assure that such Shares may be issued as provided herein without violation of any applicable law or regulation, or
of any requirements of any trading market upon which the Common Stock may be listed. The Company covenants that all Shares which
may be issued upon the exercise of the purchase rights represented by this Warrant will, upon exercise of the purchase rights represented
by this Warrant and payment for such Shares in accordance herewith, be duly authorized, validly issued, fully paid and nonassessable
and free from all taxes, liens and charges created by the Company in respect of the issue thereof (other than taxes in respect
of any transfer occurring contemporaneously with such issue).

 

(e)          Warrant
Shares Report. In each case of any adjustment or readjustment in the Warrant Shares issuable upon the exercise of this Warrant,
the Company at its sole expense will upon request promptly compute such adjustment or readjustment in accordance with the terms
of this Warrant and, upon request in connection with the preparation of the Company’s quarterly financial statements, prepare
a report setting forth such adjustment or readjustment and showing in reasonable detail the method of calculation thereof and the
facts upon which such adjustment or readjustment is based, including a statement of (i) the consideration received or to be received
by the Company for any additional shares issued or sold or deemed to have been issued, (ii) the number of shares of Common Stock
outstanding or deemed to be outstanding, and (iii) the Purchase Price in effect immediately prior to such issue or sale and as
adjusted and readjusted on account thereof. The Company will forthwith mail a copy of each such report to Holder and will, upon
the written request at any time of Holder, furnish to Holder a like report setting forth the Purchase Price at the time in effect
and showing in reasonable detail how it was calculated. The Company will also keep copies of all such reports at its principal
executive office and will cause the same to be available for inspection at such office during normal business hours by Holder or
any prospective purchaser or assignee of this Warrant designated by the Holder.

 

    	 	8	 

     

    

 

(f)          Jurisdiction.
All questions concerning the construction, validity, enforcement and interpretation of this Warrant shall be determined in accordance
with the laws of the State of Michigan.

 

(g)          Restrictions.
The Holder acknowledges that the Shares acquired upon the exercise of this Warrant, if not registered, will have restrictions upon
resale and other matters imposed by state and federal securities laws, this Warrant, the Shareholder Agreement, and the Voting
Agreement to the extent applicable upon and following exercise of this Warrant. The Holder agrees, as a condition to exercise of
this Warrant, to become a party to and to be bound by the Shareholder Agreement and the Voting Agreement, and any subsequent amendments
to either, to the extent applicable upon and following the exercise of this Warrant. The parties acknowledge that the Shareholder
Agreement and Voting Agreement may contain provisions that terminate such documents upon the closing of a public offering of Common
Stock, among other provisions. To the extent that any such agreement is terminated or no longer applicable, the Holder shall not
be required to become a party to it or be bound by it.

 

(h)          Nonwaiver.
No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder shall operate as a waiver of
such right or otherwise prejudice the Holder's rights, powers or remedies.

 

(i)          Notices.
Any notice, request or other document required or permitted to be given or delivered to the Holder by the Company shall be delivered
to the Holder at the address provided herein by Holder in Exhibit C, attached hereto. if the Holder has not provided contact
information in Exhibit C, the Company shall be entitled to use the contact information of the Holder in the Company's books
and records.

 

(j)          Limitation
of Liability. No provision hereof, in the absence of any affirmative action by the Holder to exercise this Warrant to purchase
Shares, and no enumeration herein of the rights or privileges of the Holder, shall give rise to any liability of the Holder for
the purchase price of any Common Stock or as a stockholder of the Company, whether such liability is asserted by the Company or
by creditors of the Company.

 

(k)          Remedies.
The Holder, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will be entitled
to specific performance of its rights under this Warrant. The Company agrees that monetary damages would not be adequate compensation
for any loss incurred by reason of a breach by it of the provisions of this Warrant and hereby agrees to waive and not to assert
the defense in any action for specific performance that a remedy at law would be adequate.

 

(l)          Successors
and Assigns. Subject to the terms of this Warrant and applicable securities laws, this Warrant and the rights and obligations
evidenced hereby shall inure to the benefit of and be binding upon the successors and permitted assigns of the Company and the
successors and permitted assigns of Holder. The provisions of this Warrant are intended to be for the benefit of any Holder from
time to time of this Warrant and shall be enforceable by the Holder or holder of Shares.

 

    	 	9	 

     

    

 

(m)          Amendment.
This Warrant may only be modified or amended or the provisions hereof waived with the written consent of the Company and the Holder.

 

(n)          Severability.
Wherever possible, each provision of this Warrant shall be interpreted in such manner as to be effective and valid under applicable
law, but if any provision of this Warrant shall be prohibited by or invalid under applicable law, such provision shall be ineffective
to the extent of such prohibition or invalidity, without invalidating the remainder of such provisions or the remaining provisions
of this Warrant.

 

(o)          Headings.
The headings used in this Warrant are for the convenience of reference only and shall not, for any purpose, be deemed a part of
this Warrant.

INVESTMENT REPRESENTATION STATEMENT

 

	INVESTOR:	 	 

 

	COMPANY:	XG Sciences, Inc., a Michigan corporation
	 	 
	SECURITIES:	THE WARRANT ISSUED ON _________ (THE “WARRANT”) AND THE SECURITIES ISSUED OR ISSUABLE UPON EXERCISE THEREOF

 

	DATE:	 	 

 

In connection with
the purchase or acquisition of the above-listed Securities, the undersigned Investor represents and warrants to, and agrees with,
the Company as follows:

 

1.          No
Registration. The Investor understands that the Securities have not been, and will not be, registered under the Securities
Act of 1933, as amended (the “Securities Act”), by reason of a specific exemption from the registration
provisions of the Securities Act, the availability of which depends upon, among other things, the bona fide nature of the
investment intent and the accuracy of the Investor’s representations as expressed herein or otherwise made pursuant hereto.

 

2.          Investment
Intent. The Investor is acquiring the Securities for investment for its own account, not as a nominee or agent, and not with
a view to, or for resale in connection with, any distribution thereof. The Investor has no present intention of selling, granting
any participation in, or otherwise distributing the Securities, nor does it have any contract, undertaking, agreement or arrangement
for the same.

 

3.          Investment
Experience. The Investor has substantial experience in evaluating and investing in private placement transactions of securities
in companies similar to the Company, and has such knowledge and experience in financial or business matters so that it is capable
of evaluating the merits and risks of its investment in the Company and protecting its own interests.

 

4.          Speculative
Nature of Investment. The Investor understands and acknowledges that its investment in the Company is highly speculative and
involves substantial risks. The Investor can bear the economic risk of its investment and is able, without impairing its financial
condition, to hold the Securities for an indefinite period of time and to suffer a complete loss of its investment.

 

5.          Access
to Data. The Investor has had an opportunity to ask questions of officers of the Company, which questions were answered to
its satisfaction. The Investor understands that any such discussions, as well as any information issued by the Company, were intended
to describe certain aspects of the Company’s business and prospects, but were not necessarily a thorough or exhaustive description.
The Investor acknowledges that any business plans prepared by the Company have been, and continue to be, subject to change and
that any projections included in such business plans or otherwise are necessarily speculative in nature, and it can be expected
that some or all of the assumptions underlying the projections will not materialize or will vary significantly from actual results.

 

    	 	16	 

     

    

 

6.          Accredited
Investor. The Investor is an “accredited investor” within the meaning of Regulation D, Rule 501(a), promulgated
by the Securities and Exchange Commission and agrees to submit to the Company such further assurances of such status as may be
reasonably requested by the Company.

 

7.          Residency.
The residency of the Investor (or, in the case of a partnership or corporation, such entity’s principal place of business)
is correctly set forth on the signature page hereto.

 

8.          Restrictions
on Resales. The Investor acknowledges that the Securities must be held indefinitely unless subsequently registered under the
Securities Act or an exemption from such registration is available. The Investor is aware of the provisions of Rule 144 promulgated
under the Securities Act, which permit resale of shares purchased in a private placement subject to the satisfaction of certain
conditions, which may include, among other things, the availability of certain current public information about the Company; the
resale occurring not less than a specified period after a party has purchased and paid for the security to be sold; the number
of shares being sold during any three-month period not exceeding specified limitations; the sale being effected through a “broker’s
transaction,” a transaction directly with a “market maker” or a “riskless principal transaction”
(as those terms are defined in the Securities Act or the Exchange Act (as defined below), as amended, and the rules and regulations
promulgated thereunder); and the filing of a Form 144 notice, if applicable. The Investor acknowledges and understands that the
Company may not be satisfying the current public information requirement of Rule 144 at the time the Investor wishes to sell
the Securities and that, in such event, the Investor may be precluded from selling the Securities under Rule 144 even if the
other applicable requirements of Rule 144 have been satisfied. The Investor understands and acknowledges that, in the event
the applicable requirements of Rule 144 are not met, registration under the Securities Act or an exemption from registration
will be required for any disposition of the Securities. The Investor understands that, although Rule 144 is not exclusive,
the Securities and Exchange Commission has expressed its opinion that persons proposing to sell restricted securities received
in a private offering other than in a registered offering or pursuant to Rule 144 will have a substantial burden of proof
in establishing that an exemption from registration is available for those offers or sales and that those persons and the brokers
who participate in the transactions do so at their own risk. The Investor acknowledges that the Securities will have restrictions
upon resale and other matters imposed by the Company’s shareholder agreement and voting agreement, to the extent applicable.
The Investor agrees to become a party to and to be bound by the Shareholder Agreement and the Voting Agreement, and any subsequent
amendments to either, to the extent applicable.

 

9.          No
Public Market. The Investor understands and acknowledges that no public market now exists for any of the securities issued
by the Company and that the Company has made no assurances that a public market will ever exist for the Company’s securities.

 

    	 	17	 

     

    

 

10.         Brokers
and Finders. The Investor has not engaged any brokers, finders or agents in connection with the Securities, and the Company
has not incurred nor will incur, directly or indirectly, as a result of any action taken by the Investor, any liability for brokerage
or finders’ fees or agents’ commissions or any similar charges in connection with the Securities.

 

11.         Legal
Counsel. The Investor has had the opportunity to review the Warrant, the exhibits and schedules attached thereto and the transactions
contemplated by the Warrant with its own legal counsel. The Investor is not relying on any statements or representations of the
Company or its agents for legal advice with respect to this investment or the transactions contemplated by the Warrant.

 

12.         Tax
Advisors. The Investor has reviewed with its own tax advisors the U.S. federal, state and local and non-U.S. tax consequences
of this investment and the transactions contemplated by the Warrant. With respect to such matters, the Investor relies solely on
such advisors and not on any statements or representations of the Company or any of its agents, written or oral. The Investor understands
that it (and not the Company) shall be responsible for its own tax liability that may arise as a result of this investment or the
transactions contemplated by the Warrant.

 

The Investor is signing this Investment
Representation Statement on the date first written above.

other affiliates of Secured Party (each, an “Affiliate”), pursuant to a certain Draw Loan Note and
Agreement (as amended, supplemented, restated or otherwise modified from time to time, “Note”) dated as of
the December 7, 2016, between Debtor and Secured Party.

 

1.           Grant
of Security Interest. Debtor grants to Secured Party a continuing security interest in all business assets of Debtor, including
without limitation:

 

(a)          all
machinery and equipment (including vehicles) and fixtures, wherever located, whether now owned or hereafter acquired by Debtor,
and all chattel paper evidencing any past, present or future leasing of the machinery, equipment or fixtures;

accounts, contract rights, chattel paper, instruments, investment property, general intangibles and letter of credit rights, wherever
located, whether now owned or hereafter acquired by Debtor;

 

(d)          all
deposit accounts, wherever located, whether now owned or hereafter acquired by Debtor;

 

(e)          all
trademarks, trade names, corporate names, business names, domain names, trade styles, trade dress, service marks, logos, source

or renewals of any of the foregoing;

 

(f)          any
letters patent of the United States or any country in which Debtor now or hereafter has title, all reissues, divisionals, continuations,
continuations-in-part, and extensions thereof, as well as any application for a letters patent in the United States or any other
country now or hereafter owned by Debtor, and all extensions or renewals of any of the foregoing;

 

     

     

    

 

(g)          any

Notwithstanding anything contained herein to the contrary, the term “Collateral” does not and shall not include
any patent rights within the meaning of that certain Restated and Amended Exclusive License Agreement between Michigan State University
and Debtor. 

 

2.           Indebtedness
Secured. The foregoing security interest is given to secure payment and performance of ALL OBLIGATIONS AND INDEBTEDNESS THAT
DEBTOR NOW AND IN THE FUTURE OWES TO SECURED PARTY AND ANY AFFILIATE under this Agreement and the Note, as well as under all other
security agreements, pledge agreements, assignments, mortgages, guaranties, notes, loan agreements, and other agreements, instruments
and documents that Debtor has signed or in the future signs relating thereto, and all extensions and renewals of such indebtedness
and obligations.

 

The indebtedness and obligations that this
Agreement secures are collectively called the “Indebtedness.”

Representations, and Agreements. Debtor warrants and represents to Secured Party, and agrees, as follows:

 

(a)          Debtor
is the owner, leasee or licensee of the Collateral, and none of the Collateral is subject to a lien, security interest, encumbrance
or claim in favor of a third party (other than Subsidiary), and no financing statement is on file in a public office covering any
of the Collateral, except in favor of Secured Party or with respect to Permitted Liens, and except that certain financing statement
No. 2013142779-9 in favor of NMHG Financial Services, Inc., which Debtor shall cause to be discharged within 30 days of this Agreement.

intellectual property registrations, recordings and applications. Debtor shall provide Secured Party with an updated Exhibit A
(1) within thirty (30) days after the date of this Agreement to list international intellectual property registrations, recordings
and applications, and (2) from time to time for any additions or deletions to such list occurring after the date of this Agreement.
Except as disclosed on Exhibit A and except for business information, know-how and trade secrets, there is no intellectual property
that is material to Obligor or Borrower.

 

(i)           Each
current employee of Debtor is bound by a nondisclosure agreement in form and substance previously disclosed to Secured Party. 

 

    	 	3	 

     

    

 

4.           Agreements
of Debtor. Debtor agrees that:

 

(a)          Debtor
shall not cause or permit any lien, security interest or encumbrance to be placed on any Collateral (other than Permitted Liens),
except in favor of Secured Party and Debtor shall not sell, assign or transfer any Collateral or permit any Collateral to be transferred
by operation of law, except for any intellectual property assigned to Subsidiary, as permitted under the Note and sales of inventory
in the ordinary course of Debtor’s business. A sale in the ordinary course of business does not include a transfer in partial
or complete satisfaction of a debt.

 

(b)          Debtor
shall maintain all records concerning the Collateral at Debtor’s chief executive office.

 

(c)          Debtor
shall furnish to Secured Party all information regarding the Collateral that Secured Party from time to time reasonably requests
and shall allow Secured Party at any reasonable time to inspect the Collateral and Debtor’s records regarding the Collateral.

 

(d)          Debtor
shall sign, file, record or obtain from third persons all subordination agreements and other documents, and shall take all other
actions, that Secured Party reasonably considers necessary or appropriate to perfect, to continue perfection of, or to maintain
first priority (except with respect to Permitted Liens) of, Secured Party’s security interest in the Collateral and Debtor
shall place upon the Collateral and/or documents evidencing the Collateral any notice of Secured Party’s security interest
that Secured Party from time to time reasonably requires. Actions that Secured Party may require Debtor to take under
the preceding sentence include, without limitation, (1) obtaining from any third party who has possession of Collateral an acknowledgment
that the third party holds the Collateral for Secured Party and (2) obtaining agreements from banks, securities intermediaries,
issuers of letters of credit and others, and taking all other actions reasonably requested by Secured Party, to give Secured Party
control of any part of the Collateral consisting of investment property, deposit accounts, letter of credit rights or electronic
chattel paper.

 

(e)          Debtor
shall immediately notify Secured Party in writing of any change in Debtor’s name, identity or organizational structure, and
of any change in the location of Debtor’s place of business and of the location of each additional place of business that
Debtor establishes. Debtor shall not make a change in its name or its organizational structure or in the jurisdiction under the
laws of which Debtor is organized, without Secured Party’s prior written consent.

 

(f)          Debtor
shall indemnify Secured Party with respect to all losses, damages, liabilities and expenses (including attorney fees) that Secured
Party incurs by reason of a failure of Debtor to comply with an obligation under this Agreement or by reason of a warranty or representation
that Debtor makes to Secured Party in this Agreement being false in any material respect.

 

    	 	4	 

     

    

 

(g)          After
the occurrence of an Event of Default (subject to applicable cure periods), Debtor shall take all steps reasonably necessary to
permit Secured Party to contact its account debtors at any time for the purpose of verifying the existence, amount and collectability
of, and other information regarding, Debtor’s accounts, chattel paper, instruments or general intangibles.

 

(h)          Debtor
shall maintain all tangible Collateral in good condition and repair and maintain special form, replacement cost property insurance
covering all tangible Collateral. As soon after closing as reasonably practicable, but no later than 30 days after closing,
each insurance policy (1) shall provide that its proceeds shall be payable to Secured Party to the extent of Secured Party's
interest in the Collateral, (2) shall contain a standard lender's loss payable endorsement in favor of Secured Party, (3) shall
provide that the policy shall not be canceled, and the coverage shall not be reduced, without at least 10 days' prior written notice
by the insurer to Secured Party and (4) shall otherwise be in form and substance satisfactory to Secured Party. Debtor shall provide
Secured Party evidence of that insurance coverage. Upon Secured Party's request, Debtor shall deliver to Secured Party all policies
that provide for such insurance. Debtor agrees that Secured Party may act as agent for Debtor in obtaining, adjusting, and settling
that insurance and endorsing any draft evidencing proceeds of it.

 

(i)           To
the extent that applicable law at any time permits a secured party to file a financing statement that is not authenticated by Debtor,
Debtor authorizes Secured Party to file one or more financing statements containing an indication that such financing statement
covers the Collateral. The financing statements that Secured Party files to perfect its security interest in the Collateral may
describe the Collateral as “all assets” or “all personal property” that Debtor now owns or acquires in
the future. If Secured Party has previously filed one or more financing statements to perfect its security interest in the Collateral,
then Debtor approves and ratifies those filings.

 

(j)           Debtor
shall pay, before they become delinquent, all taxes and assessments upon the Collateral or for its use or operation and pay and
perform when due all indebtedness and obligations under all leases, land contracts or other agreements under which Debtor has possession
of any real property upon which any of the Collateral is at any time located and under any mortgage or mortgages at any time covering
that real property.

 

(k)          Debtor
shall prepare, execute, acknowledge and deliver to Secured Party an instrument in writing in recordable form for recording a lien
on and security interest in and to all of its right, title and interest in, to and under all new patent and trademark application
filings and any rights extending therefrom, either in the United States or any other country and all proceeds of any and all of
the foregoing, within one month after the filing of any such applications.

 

(l)           Debtor
shall timely enter into a nondisclosure agreement, in form and substance reasonably acceptable to Secured Party, with each new
employee, manager, director, and officer of Debtor, and all agents and other parties to whom trade secrets or other confidential
information of Debtor or any affiliate of Debtor may be disclosed.

 

    	 	5	 

     

    

 

(m)         Debtor
shall not commit any material breach or default under that certain license agreement between Debtor and Michigan State University
dated as of July 27, 2007 and amended on May 24, 2010 and May 27, 2011, as it may be amended, restated, renewed, extended, replaced,
or modified.

 

5.           Secured
Party’s Right to Perform. If Debtor fails to perform an obligation of Debtor under this Agreement, then Secured Party
may, without giving notice to or obtaining the consent of Debtor, perform that obligation on behalf of Debtor. Debtor shall reimburse
Secured Party on demand for any expense that Secured Party incurs in performing the obligation and shall pay to Secured Party interest
on each expense, from the date the expense was incurred by Secured Party, at 5% per annum (“Default Rate”).
Secured Party is not required to perform an obligation that Debtor has failed to perform. If Secured Party does so, then that shall
not be a waiver of Secured Party’s right to declare the Indebtedness immediately due and payable by reason of Debtor’s
failure to perform.

 

6.           Events
of Default and Acceleration. Any part or all of the Indebtedness shall, at the option of Secured Party, become immediately
due and payable without notice or demand upon the occurrence of any of the following events of default (each, an “Event
of Default”):

 

(a)          If
an Event of Default occurs under and as defined in the Note, including any default in the payment or performance of any of the
Indebtedness, when and as it is due and payable subject to applicable grace periods.

 

(b)          If
Debtor fails  to perform any other material obligation, covenant or agreement of Debtor to Secured Party under
this Agreement, under a promissory note or other instrument that at any time evidences any Indebtedness or under any other security
agreement, loan agreement, mortgage, assignment, guaranty or other agreement that now or in the future secures or relates to any
Indebtedness (“Security Documents”).

 

(c)          If
a warranty, representation, or statement that has been or in the future is made to Secured Party by Debtor or by a guarantor of
all or part of the Indebtedness (“Guarantor”) in this Agreement or in a Security Document shall have been false
in any material respect when made or furnished.

 

(d)          If
Debtor or a Guarantor dissolves, becomes insolvent or makes an assignment for the benefit of creditors.

 

(e)          If
a guaranty that now or in the future secures payment or performance of all or a part of the Indebtedness is terminated, revoked
or limited for any reason, without Secured Party’s written consent or agreement.

 

    	 	6	 

     

    

 

(f)          If
an attachment, garnishment, levy, execution or other legal process is at any time issued against or placed upon any of the Collateral
(other than with respect to Permitted Liens) and is not terminated or released within 30 days.

 

(g)          If
all or a substantial part of the tangible Collateral is destroyed or materially damaged by fire or other casualty, and cannot be
repaired or replaced within a commercially reasonable time, not to exceed 90 days, whether or not there is insurance coverage for
the damage or destruction.

 

If an  Event of Default  is capable
of being cured, then Debtor may cure the same during the thirty-day period that begins on the date on which Debtor receives
notice from Secured Party or otherwise has actual knowledge,  of the event  (the “Cure Period”). An Event of Default that is capable of being cured will not be deemed to
have occurred as a result of an event during the Cure Period for that event or, if the event is cured during the Cure
Period, thereafter.

 

If a voluntary or involuntary case in bankruptcy,
receivership or insolvency is at any time begun by or against Debtor or a Guarantor or if any attachment, garnishment, levy, execution
or other legal process is at any time issued against or placed upon Collateral and not terminated or released within 30 days, then
the entire Indebtedness shall automatically become immediately due and payable, without notice or demand. All or part of the Indebtedness
also may become, or may be declared to be, immediately due and payable under the terms of the Note or a note that at any
time evidences any Indebtedness or under a Security Document that has been or in the future is entered into between Debtor and
Secured Party.

 

7.           Secured
Party’s Rights and Remedies. Secured Party shall have all rights and remedies of a secured party under applicable laws.
Without limiting those rights and remedies, upon the occurrence of an Event of Default (subject to applicable cure periods):

 

(a)          (1)
Without notice or demand to Debtor, Secured Party shall be entitled to notify Debtor’s account debtors and obligors to make
all payments directly to Secured Party, and Secured Party shall have the right to take all actions that Secured Party reasonably
considers necessary or desirable to collect upon the Collateral, including, without limitation, prosecuting actions against, or
settling or compromising disputes and claims with, Debtor’s account debtors and obligors, (2) without notice or demand
to Debtor, Secured Party may receive, open, dispose of and notify the postal authorities to change the address of, mail directed
to Debtor, and (3) upon Secured Party’s demand, Debtor shall immediately deliver to Secured Party, at the place that
Secured Party designates, all proceeds of the Collateral and all books, records, agreements, leases, documents and instruments
that evidence or relate to the Collateral.

 

(b)          Debtor,
upon Secured Party’s demand, shall assemble the Collateral and proceeds of Collateral at Debtor’s place of business,
and Secured Party may dispose of the Collateral in any commercially reasonable manner. Any notification that Secured Party is required
to give to Debtor regarding sale or other disposition of Collateral shall be considered reasonable if it is mailed at least 10
days before the sale or other disposition. In connection with a disposition of Collateral, Secured Party may comply with the requirements
of an applicable state or federal law or regulation, and such compliance shall not cause the disposition to not be commercially
reasonable.

 

    	 	7	 

     

    

 

(c)          Secured
Party shall have the right (but no obligation) to continue or complete the manufacturing or processing of, or other operations
in connection with, any part of the Collateral, and, for that purpose, to enter and remain upon or in any land or buildings
that are possessed by Debtor or that Debtor has the right to possess. Debtor shall reimburse Secured Party on demand for any net
expense that Secured Party incurs in connection with those activities and shall pay to Secured Party interest on each net expense,
from the date on which Secured Party incurred the expense, at the Default Rate.

 

The proceeds of any collection or disposition
of Collateral shall be applied first to Secured Party's attorney fees and expenses, as provided in Paragraph 8 of this Agreement,
then to the unpaid interest accrued on the Indebtedness and then to the principal of the Indebtedness, and Debtor shall be liable
for any deficiency. Secured Party does not have any obligation to prepare or process any Collateral for sale or other disposition.
If Secured Party sells any of the Collateral on credit, then Debtor will be credited only with payments that the purchaser actually
makes and that Secured Party receives and applies to the unpaid balance of the purchase price of the Collateral. If the purchaser
fails to pay for the Collateral, then Secured Party may again dispose of the Collateral and apply the proceeds in accordance with
this paragraph. All rights and remedies of Secured Party under this Agreement, whether or not exercisable only on default, shall
be cumulative and may be exercised from time to time. No delay by Secured Party in the exercise of any right or remedy shall operate
as a waiver thereof, and no single or partial exercise of any right or remedy shall preclude other or further exercise thereof
or the exercise of any other right or remedy.

 

8.           Expenses.
Debtor shall reimburse Secured Party on demand for all reasonable attorney fees, legal expenses, and other expenses that Secured
Party incurs in perfecting (subject to the $25,000 limitation in the Note), protecting and enforcing its interest in the Collateral
and its rights under this Agreement. This includes fees and expenses incurred in trying to take possession of Collateral from Debtor,
a trustee or receiver in bankruptcy, or any other person. Secured Party may apply any proceeds of collection or disposition of
Collateral to Secured Party's attorney fees, legal expenses and other out-of-pocket expenses.

 

9.           Amendments
and Waivers. No provision of this Agreement may be modified or waived except by a written agreement signed by Secured
Party and Debtor. Secured Party will continue to have all of its rights under this Agreement even if it does not fully and
promptly exercise them on all occasions. Secured Party may, at its option: waive any default; defer an action on any default; extend
or modify the time or manner of payment of the Indebtedness or waive or modify any term or condition relating to the Indebtedness;
release Collateral or other security for the Indebtedness; release any person liable for any of the Indebtedness, including Debtor;
or make advances or other extensions of credit secured hereby; all without giving Debtor notice or obtaining Debtor's consent.
Any such action by Secured Party will not release or impair its security interest in the Collateral or Debtor's obligations
under this Agreement. Secured Party's security interest in the Collateral and Debtor's obligations under this Agreement will not
be released or impaired if Secured Party fails to obtain, perfect, or secure priority of any other security for the Indebtedness
that is agreed to be given, or is given, by anyone else. Secured Party is not required to sue upon or otherwise enforce payment
of the Indebtedness or any other security before exercising its rights under this Agreement.

 

    	 	8	 

     

    

 

10.         Notices.
Any notices or communications required or permitted under this Agreement shall be governed by the Note.

 

11.         Terminology;
Conflicts. Capitalized terms that are not otherwise defined in this Agreement shall have the meanings set forth in the Note.
Other terms used in this Agreement shall have the meanings set forth in the Uniform Commercial Code as in effect in the State of
Michigan on the date of this Agreement. In the event of a conflict between the terms of this Agreement and the Note, the terms
of the Note control.

 

12.         Binding
Effect. This Agreement shall be binding upon and inure to the benefit of Debtor and Secured Party and their respective successors
and assigns.

 

13.         Termination.
Upon the payment in full and termination of the Note and the Security Documents, this Agreement shall terminate and Secured
Party shall execute, acknowledge and deliver to Debtor an instrument in writing, prepared by debtor, in recordable
form releasing its liens and security interests in the Collateral under this Agreement.

 

SECURED PARTY AND
DEBTOR EACH IRREVOCABLY AND UNCONDITIONALLY WAIVES ITS RIGHT TO A TRIAL BY JURY IN ANY ACTION, INCLUDING A CLAIM, COUNTERCLAIM,
CROSS-CLAIM OR THIRD-PARTY CLAIM (“CLAIM”), THAT IS BASED UPON, ARISES OUT OF OR RELATES TO THIS SECURITY AGREEMENT
OR THE INDEBTEDNESS, INCLUDING, WITHOUT LIMITATION, ANY CLAIM THAT IS BASED UPON, ARISES OUT OF OR RELATES TO AN ACTION OR INACTION
OF SECURED PARTY IN CONNECTION WITH AN ACCELERATION OF THE INDEBTEDNESS OR AN ENFORCEMENT OF SECURED PARTY’S SECURITY INTEREST
IN THE COLLATERAL.

Exhibit A

 

List of Intellectual Property

 

Michigan State University License

 

We have acquired an exclusive license for a number of
inventions from Michigan State University. These rights are embodied in a Technology Licensing Agreement between XGS and
Michigan State University dated July 27, 2007 and amended on May 24, 2010 and May 27, 2011, which owns the rights to all
intellectual property resulting from research performed at the University. This Agreement gives us the exclusive worldwide
rights to the subject intellectual property in its field. In exchange for the rights to the technology covered by this
Agreement, we paid MSU an initial fee and agreed to pay ongoing royalties on the basis of material sold by us in future
years. Under a previous version of the Licensing Agreement, we also awarded a small amount of common stock to MSU. The
intellectual property covered by the Agreement is in various stages of development and legal protection. Because there is an
active research program underway in this area, we also anticipate that we may add other MSU inventions to our Agreement. In
some limited cases, depending on the source of research funds, other parties may have limited rights to use the inventions
covered by these agreements. This is typical in the case of research funded by U.S. government agencies and is sometimes the
case when research has been funded or partially funded by private corporations.

 

As of November 1, 2016 the following technologies were included
in the MSU License Agreements with XGS and were being actively prosecuted at the U.S. Patent Office:

 

		·	U.S. Patent Application No. 12/587,645. “Electrically Conductive, Optically Transparent Films of Exfoliated Graphite
NanoParticles & Methods of Making the Same”

 

		·	U.S. Patent Application No. 13/199,086. “PI Coupling Agents for Dispersion of Graphene NanoPlatelets in Polymers”,
allowed but not yet granted 

 

		·	U.S. Patent 8,834,959. “Method for the Preparation of Doped Single Graphene Sheets”

 

Our Patent Filings

 

In addition to the patent applications related to MSU technology
discussed above, we also file for patents on some of our own inventions. As of November 1, 2016 the following patents and patent
applications were being managed by us and our patent attorneys:

 

		·	U.S. Patent Application No. 15/155,558. “Process of Dry Milling Particulate Materials”

 

		·	U.S. Patent Application No. 13/686,961. “Single Mode Microwave Device for Producing Exfoliated Graphite”

 

		·	U.S. Patent Application No. 14/201,986. “Graphene Carbon Compositions”

Global Patent Filings

 

For each patent application filed in the US, we make a determination
on the nature and value of the patent. For many of the applications filed in the US, additional filings are made in other countries
such as the European Union, Japan, South Korea, China, Taiwan or other applicable countries. These filings and analyses are made
on a case-by-case basis. Typically, patents that are defensive in nature are not filed abroad, while those that are protective
of active XGS products or application areas are filed in relevant countries abroad. Granted/allowed patents only listed here.
