securities governed by Article 8 of the Uniform Commercial Code as in effect in any relevant jurisdiction.

 

		(4)	For so long as the Company shall have the right to vote the Pledged Interests owned by it, the
Company covenants and agrees that it will not, without the prior written consent of the Secured Parties, vote or take any consensual
action with respect to such Pledged Interests which would materially adversely affect the rights of the Secured Parties or the
value of the Pledged Interests.

 

4.04       Events
of Default, etc.  During the period during which an Event of Default shall have occurred and be continuing:

 

		a.	the Company shall, at the request of the Agent, assemble the Collateral owned by it at such place
or places, reasonably convenient to both the Agent and the Company, designated in its request;

 

		b.	the Agent may make any reasonable compromise or settlement deemed desirable with respect to any
of the Collateral and may extend the time of payment, arrange for payment in installments, or otherwise modify the terms of, any
of the Collateral;

 

    	 	8	 

     

    

  

		c.	the Agent shall have all of the rights and remedies with respect to the Collateral of a secured
party under the Uniform Commercial Code (whether or not said Code is in effect in the jurisdiction where the rights and remedies
are asserted) and such additional rights and remedies to which a secured party is entitled under the laws in effect in any jurisdiction
where any rights and remedies hereunder may be asserted, including, without limitation, the right, to the maximum extent permitted
by law, to exercise all voting, consensual and other powers of ownership pertaining to the Collateral as if the Agent were the
sole and absolute owner thereof (and the Company agrees to take all such action as may be appropriate to give effect to such right);

 

		d.	the Agent in its discretion may, in its name or in the name of the Company or otherwise, demand,
sue for, collect or receive any money or property at any time payable or receivable on account of or in exchange for any of the
Collateral, but shall be under no obligation to do so; and

 

		e.	the Agent may, upon ten (10) Business Days’ prior written notice to the Company of the time
and place, with respect to the Collateral or any part thereof which shall then be or shall thereafter come into the possession,
custody or control of the Agent, or any of its respective agents, sell, lease, assign or otherwise dispose of all or any of such
Collateral, at such place or places as the Agent deems best, and for cash or on credit or for future delivery (without thereby
assuming any credit risk), at public or private sale, without demand of performance or notice of intention to effect any such disposition
or of time or place thereof (except such notice as is required above or by applicable statute and cannot be waived) and the Agent
or anyone else may be the purchaser, lessee, assignee or recipient of any or all of the Collateral so disposed of at any public
sale (or, to the extent permitted by law, at any private sale), and thereafter hold the same absolutely, free from any claim or
right of whatsoever kind, including any right or equity of redemption (statutory or otherwise), of the Company, any such demand,
notice or right and equity being hereby expressly waived and released. In the event of any sale, assignment, or other disposition
of any of the Trademark Collateral, the goodwill of the Business connected with and symbolized by the Trademark Collateral subject
to such disposition shall be included, and the Company shall supply to the Agent or its designee, for inclusion in such sale, assignment
or other disposition, all Intellectual Property relating to such Trademark Collateral. The Agent may, without notice or publication,
adjourn any public or private sale or cause the same to be adjourned from time to time by announcement at the time and place fixed
for the sale, and such sale may be made at any time or place to which the same may be so adjourned.

 

The proceeds of each collection, sale or
other disposition under this Section 4.04, including by virtue of the exercise of the license granted to the Agent in Section 4.03(a)(1)
hereof, shall be applied in accordance with Section 4.07 hereof.

 

4.05     Deficiency.  If
the proceeds of sale, collection or other realization of or upon the Collateral pursuant to Section 4.04 hereof are insufficient
to cover the costs and expenses of such realization and the payment in full of the Secured Obligations, the Company shall remain
liable for any deficiency.

 

4.06      Removals,
etc.  Without at least thirty (30) days’ prior written notice to the Agent or unless otherwise
required by law, the Company shall not (i) maintain any of its books or records with respect to the Collateral at any office or
maintain its chief executive office or its principal place of business at any place, or permit any Inventory or Equipment to be
located anywhere other than at one of the locations identified in Annex 3 hereto
or in transit from one of such locations to another; or (ii) change its corporate
name, or the name under which it does business, from the name shown on the signature page hereto.

 

    	 	9	 

     

    

  

4.07       Application
of Proceeds.  Except as otherwise herein expressly provided, the proceeds of any collection, sale
or other realization of all or any part of the Collateral pursuant hereto, and any other cash at the time held by the Agent under
this Section 4, shall be applied by the Agent:

 

First,
to the payment of the costs and expenses of such collection, sale or other realization, including reasonable out-of-pocket costs
and expenses of the Agent and the fees and expenses of its agents and counsel, and all expenses, and advances made or incurred
by the Agent in connection therewith;

 

Next,
to the payment in full of the Secured Obligations in each case equally and ratably in accordance with the respective amounts thereof
then due and owing to each of the Secured Parties; and

 

Finally,
to the payment to the Company, or its successors or assigns, or as a court of competent jurisdiction may direct, of any surplus
then remaining.

 

As used in this Section 4, “proceeds”
of Collateral shall mean cash, securities and other property realized in respect of, and distributions in kind of, Collateral,
including any thereof received under any reorganization, liquidation or adjustment of debt of the Company or any issuer of or obligor
on any of the Collateral.

 

4.08       Attorney-in-Fact.  Without
limiting any rights or powers granted by this Agreement to the Agent while no Event of Default has occurred and is continuing,
upon the occurrence and during the continuance of any Event of Default, the Agent is hereby appointed the attorney-in-fact of the
Company for the purpose of carrying out the provisions of this Section 4 and taking any action and executing any instruments which
the Agent may deem necessary or advisable to accomplish the purposes hereof, which appointment as attorney-in-fact is irrevocable
and coupled with an interest. Without limiting the generality of the foregoing, so long as the Secured Parties shall be entitled
under this Section 4 to make collections in respect of the Collateral, the Agent shall have the right and power to receive, endorse
and collect all checks made payable to the order of the Company representing any dividend, payment, or other distribution in respect
of the Collateral or any part thereof and to give full discharge for the same.

 

4.09       Perfection.  Prior
to or concurrently with the execution and delivery of this Agreement, the Company shall file such financing statements and other
documents in such offices as the Agent may request to perfect or maintain the security interests granted by Section 3 of this Agreement;
and without limiting the Company’s obligations with respect to perfection of the security interests, the Company hereby authorizes
the Agent to file all such financing statements and other documents and, at Agent’s option, to describe the Collateral in
any such financing statement as “all personal property”.

 

4.10       Termination.  When
all Secured Obligations shall have been paid in full under the Subscription Agreements, this Agreement shall terminate, and the
Agent shall forthwith cause to be assigned, transferred and delivered, against receipt but without any recourse, warranty or representation
whatsoever, any remaining Collateral and money received in respect thereof, to or on the order of the Company and to be released
and cancelled all licenses and rights referred to in Section 4.03(a)(1) hereof. The Agent shall also execute and deliver to the
Company upon such termination such Uniform Commercial Code termination statements and such other documentation as shall be reasonably
requested by the Company to effect the termination and release of the liens on the Collateral.

 

4.11       Expenses.  The
Company agrees to pay to the Agent all out-of-pocket expenses (including reasonable expenses for legal services of every kind)
of, or incident to, the enforcement of any of the provisions of this Section 4, or performance by the Agent of any obligations
of the Company in respect of the Collateral which the Company has failed or refused to perform upon reasonable notice, or any actual
or attempted sale, or any exchange, enforcement, collection, compromise or settlement in respect of any of the Collateral, and
for the care of the Collateral and defending or asserting rights and claims of the Agent in respect thereof, by litigation or otherwise,
including expenses of insurance, and all such expenses shall be Secured Obligations to the Agent secured under Section 3 hereof.
Each Secured Party agrees to advance to the Agent his/her/its pro rata share of any funds requested by the Agent to carry out the
intent and purposes of this Agreement according to each Secured Party’s pro rata share of the total aggregate principal amount
outstanding under the Notes at the time such request for advance is made. Any such advances will be refunded to the Secured Parties
to the extent the Company reimburses the Agent for its expenses or the Agent makes recoveries from the disposition of the Company’s
assets.

 

    	 	10	 

     

    

  

4.12       Further
Assurances.  The Company agrees that, from time to time upon the written request of the Agent, the
Company will execute and deliver such further documents and do such other acts and things as the Agent may reasonably request in
order fully to effect the purposes of this Agreement.

the other provisions hereof shall remain in full force and effect in such jurisdiction and shall be liberally construed

The
Patent Rights within the meaning of that certain Restated and Amended Exclusive License Agreement between Michigan State University
and the Company.

 

     

     

    

 

SECOND AMENDED AND RESTATED SECURITY
AGREEMENT

 

ANNEX
2 - EXCEPTIONS FOR COPYRIGHTS, PATENTS AND TRADEMARKS

 

The
Company has distribution agreements with sales agents and other companies that allow the use of the Company’s trademarks
n the normal course of business.

 

The
Company has licensed the below listed production and manufacturing technology to the following licensees:

 

Cabot
Corporation – production technology for the production of graphene nanoplatelets as more fully defined in the LICENSE AGREEMENT
BETWEEN

CABOT
CORPORATION AND XG SCIENCES INC. dated November 1, 2011 and amended on January 23, 2013

 

POSCO
- production technology for the production of graphene nanoplatelets as more fully defined in the LICENSE AGREEMENT between XG
Sciences, Inc. and POSCO dated June 8, 2011

 

In
November of 2011, the Company entered into a license agreement between the Company and Cabot Corporation (“Cabot”),
a copy of which has been supplied to AAOF (the “License Agreement”). Subsequent to the execution of the License Agreement,
Michigan State University (“MSU”) expressed concern regarding the form of the License Agreement, including whether
any MSU technology might have been included in the License Agreement. After discussions among Cabot, MSU, and the Company, Cabot
drafted a First Amendment to the License Agreement Between Cabot and the Company (the “Amendment”). The Amendment contains
warranties, attested by both the Company and its Chief Scientist, Dr. Lawrence Drzal, asserting that no MSU technology had been
improperly transferred to Cabot. The Company executed the Amendment on January 29, 2013, and has provided a copy to AAOF. The Company
understood that this matter was closed when it provided the Amendment to AAOF. However, the Company subsequently learned that Cabot
has not yet signed the Amendment because a new Vice President had been appointed. Additionally, the Company received a letter from
MSU dated March 20, 2013 stating that MSU wanted to review this issue. The Company, Cabot, and MSU are currently renegotiating
the Amendment. MSU is currently engaged in an audit of the technology transfer package associated with the Cabot License Agreement.
