(b)           No
Public Sale or Distribution. Such Buyer (i) is acquiring its Note, and (ii) upon conversion of its Note will acquire the Conversion

with, the public sale or distribution thereof in violation of applicable securities laws, except pursuant to sales registered or
exempted under the 1933 Act; provided, however, by making the representations herein, such Buyer does not agree, or make any representation
or warranty, to hold any of the Securities for any minimum or other specific term and reserves the right to dispose of the Securities
at any time in accordance with or pursuant to a registration statement or an exemption under the 1933 Act. Such Buyer does not
presently have any agreement or understanding, directly or indirectly, with any Person (as defined below) to distribute any of
the Securities in violation of applicable securities laws.

from the registration requirements of United States federal and state securities laws and that the Company is relying in part upon
the truth and accuracy of, and such Buyer’s compliance with, the representations, warranties, agreements, acknowledgments
and understandings of such Buyer set forth herein in order to determine the availability of such exemptions and the eligibility
of such Buyer to acquire the Securities.

 

(e)           Information.
Such Buyer and its advisors, if any, have been furnished with the Company’s private placement memorandum dated February 25,
2016 (the “Private Placement Memorandum”) and with all other materials relating to the business, finances and
operations of the Company and materials relating to the offer and sale of the Securities which have been requested by such Buyer.

that its investment in the Securities involves a high degree of risk. Such Buyer has sought such accounting, legal and tax advice
as it has considered necessary to make an informed investment decision with respect to its acquisition of the Securities.

Governmental Review. Such Buyer understands that no United States federal or state agency or any other government or governmental
agency has passed on or made any recommendation or endorsement of the Securities or the fairness or suitability of the investment

for sale, sold, assigned or transferred unless (A) subsequently registered thereunder, (B) such Buyer shall have delivered to the
Company (if requested by the Company) an opinion of counsel to such Buyer, in a form reasonably acceptable to the Company, to the
effect that such Securities to be sold, assigned or transferred may be sold, assigned or transferred pursuant to an exemption from
such registration, or (C) such Buyer provides the Company with reasonable assurance and documentation as may be requested by the
Company or its legal counsel that such Securities can be sold, assigned or transferred pursuant to Rule 144 or Rule 144A promulgated
under the 1933 Act (or a successor rule thereto) (collectively, “Rule 144”); (ii) any sale of the Securities
made in reliance on Rule 144 may be made only in accordance with the terms of Rule 144, and further, if Rule 144 is not applicable,
any resale of the Securities under circumstances in which the seller (or the Person through whom the sale is made) may be deemed
to be an underwriter (as that term is defined in the 1933 Act) may require compliance with some other exemption under the 1933
Act or the rules and regulations of the SEC promulgated thereunder; and (iii) neither the Company nor any other Person is under
any obligation to register the Securities under the 1933 Act or any state securities laws or to comply with the terms and conditions
of any exemption thereunder.

Enforcement. This Agreement and the other Transaction Documents executed by the Buyer have been duly and validly authorized,
executed and delivered on behalf of such Buyer and constitutes the legal, valid and binding obligations of such Buyer enforceable

Conflicts. The execution, delivery and performance by such Buyer of this Agreement and the other Transaction Documents executed
by the Buyer and the consummation by such Buyer of the transactions contemplated hereby and thereby will not (i) result in a violation
of the organizational documents of such Buyer, (ii) conflict with, or constitute a default (or an event which with notice or lapse
of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation
of, any agreement, indenture or instrument to which such Buyer is a party or (iii) result in a violation of any law, rule, regulation,
order, judgment or decree (including federal and state securities laws) applicable to such Buyer, except in the case of clauses

be expected to have a material adverse effect on the ability of such Buyer to perform its obligations hereunder.

 

(j)            Buyer’s
Principal Residence/Office. The address of Buyer’s principal residence, if Buyer is a natural Person, or principal office,
if Buyer is a non-natural Person, such as a corporation, limited liability company or other entity, is set forth on the Buyer’s

makes such qualification necessary, except to the extent that the failure to be so qualified or be in good standing would not be
reasonably expected to have a Material Adverse Effect. “Material Adverse Effect” means any material adverse
effect on (i) the business, properties, assets, liabilities, operations (including results thereof) or condition (financial or
otherwise) of the Company, either individually or taken as a whole, (ii) the transactions contemplated hereby or in any of the
other Transaction Documents, or (iii) the authority or ability of the Company to perform any of its obligations under any of the
Transaction Documents. The Company has no Subsidiaries. “Subsidiaries” means any Person in which the Company,
directly or indirectly, owns a majority of the outstanding capital stock or holds any equity or similar interest of such Person,
and each of the foregoing, is individually referred to herein as a “Subsidiary.” Additionally, to the extent
that any Subsidiary is hereafter created, and the context of the provision of this Agreement would ordinarily include a Subsidiary,
then the term “Company” will be deemed to include such Subsidiary.

Agreement and the other Transaction Documents and to issue the Securities in accordance with the terms hereof and thereof. The
execution and delivery of this Agreement and the other Transaction Documents by the Company, and the consummation by the Company
of the transactions contemplated hereby and thereby (including, without limitation, the issuance of the Notes and the reservation
for issuance and issuance of the Conversion Shares issuable upon conversion of the Notes) have been duly authorized by the Company’s
board of directors or other governing body, as applicable, and (other than the filing with the SEC of one or more Registration
Statements (as defined in the Registration Rights Agreement) in accordance with the requirements of the Registration Rights Agreement,
a Form D with the SEC and any other filings as may be required by any state securities agencies) no further filing, consent or
authorization is required by the Company, its respective boards of directors or the stockholders or other governing body. This
Agreement has been, and the other Transaction Documents will be prior to the Closing, duly executed and delivered by the Company,
and each constitutes the legal, valid and binding obligations of the Company, enforceable against the Company in accordance with
its respective terms, except as such enforceability may be limited by general principles of equity or applicable bankruptcy, insolvency,
reorganization, moratorium, liquidation or similar laws relating to, or affecting generally, the enforcement of applicable creditors’
rights and remedies and except as rights to indemnification and to contribution may be limited by federal or state securities law.
“Transaction Documents” means, collectively, this Agreement, the Notes, the Security Documents, the Registration
Rights Agreement, the Irrevocable Transfer Agent Instructions (as defined in the Registration Rights Agreement) and each of the
other agreements and instruments entered into or delivered by any of the parties hereto in connection with the consummation of
the transactions contemplated hereby and thereby, as may be amended from time to time.

 

(c)           Issuance

fully paid and non-assessable and free from all preemptive or similar rights, taxes, liens, charges and other encumbrances with
respect to the issue thereof under the terms thereof, with the holders being entitled to all rights accorded to a holder of Common
Stock. The Company shall have reserved from its duly authorized capital stock not less than one hundred ten percent (110%) of the
maximum number of Conversion Shares issuable upon conversion of the Notes in accordance with their terms. Subject to the accuracy
of the representations and warranties of the Buyers in this Agreement, the offer and issuance by the Company of the Securities
is exempt from registration under the 1933 Act.

 

(d)           No
Conflicts. The execution, delivery and performance of the Transaction Documents by the Company and the consummation by the
Company of the transactions contemplated hereby and thereby (including, without limitation, the issuance of the Notes, the Conversion
Shares upon conversion of the Notes, the reservation for issuance of the Conversion Shares and the creation of the security interests
represented by the Security Documents) will not (i) result in a violation of the Certificate of Incorporation (as defined below)
(including, without limitation, any certificate of designation contained therein) or other organizational documents of the Company,
any capital stock of the Company or Bylaws (as defined below) of the Company, (ii) conflict with, or constitute a default (or an
event which with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment,
acceleration or cancellation of, any agreement, indenture or instrument to which the Company is a party, including, without limitation,
the 2015 Convertible Notes, or (iii) result in a violation of any law, rule, regulation, order, judgment or decree (including,
without limitation, foreign, federal and state securities laws and regulations) applicable to the Company or by which any property
or asset of the Company is bound or affected except, in the case of clause (ii) or (iii) above, to the extent such violations that
could not reasonably be expected to have a Material Adverse Effect.

Other than the consent of the Earlier Investors, the Company is not required to obtain any consent from, authorization or order
of, or make any filing or registration with (other than the filing with the SEC of one or more Registration Statements in accordance
with the requirements of the Registration Rights Agreement, a Form D with the SEC and any other filings as may be required by any
state securities agencies), any court, governmental agency or any regulatory or self-regulatory agency or any other Person in order
for it to execute, deliver or perform any of its respective obligations under, or contemplated by, the Transaction Documents, in
each case, in accordance with the terms hereof or thereof. All consents, authorizations, orders, filings and registrations which
the Company is required to obtain at or prior to the Closing have been or will be obtained or made on or prior to the Closing Date,
and the Company is not aware of any facts or circumstances which might prevent the Company from obtaining or effecting any of the
registration, application or filings contemplated by the Transaction Documents.

 

(f)            Acknowledgment
Regarding Buyer’s Purchase of Securities. The Company acknowledges that no Buyer is acting as a financial advisor or
fiduciary of the Company (or in any similar capacity) with respect to the Transaction Documents and the transactions contemplated
hereby and thereby, and any advice given by a Buyer or any of its representatives or agents in connection with the Transaction
Documents and the transactions contemplated hereby and thereby is merely incidental to such Buyer’s purchase of the Securities.
The Company further represents to each Buyer that the Company’s decision to enter into the Transaction Documents to which
it is a party has been based solely on the independent evaluation by the Company and its respective representatives.

 

(g)           No
General Solicitation; Placement Agent’s Fees. Neither the Company nor any Person acting on its behalf, has engaged in
any form of general solicitation or general advertising (within the meaning of Regulation D) in connection with the offer or sale
of the Securities. The Company shall be responsible for the payment of any Placement Agent’s fees, financial advisory fees,
or brokers’ commissions (other than for Persons engaged by any Buyer or its investment advisor) relating to or arising out
of the transactions contemplated hereby. Other than the Placement Agent, to which a cash fee of 10% of the gross proceeds and a
warrant equal to 10% of the Conversion Shares, the Company has not engaged any placement agent or other broker or dealer in connection
with the offer or sale of the Securities.

Integrated Offering. None of the Company or, to its knowledge, any of its affiliates, nor any Person acting on its behalf has,
directly or indirectly, made any offers or sales of any security or solicited any offers to buy any security, under circumstances
that would require registration of the issuance of any of the Securities under the 1933 Act, whether through integration with prior
offerings or otherwise, or cause this offering of the Securities to require approval of stockholders of the Company under any applicable
stockholder approval provisions. None of the Company, nor its affiliates nor any Person acting on their behalf will take any action
or steps that would require registration of the issuance of any of the Securities under the 1933 Act or cause the offering of any
of the Securities to be integrated with other offerings of securities of the Company.

 

(i)            Dilutive
Effect. The Company understands and acknowledges that the number of Conversion Shares may increase in certain circumstances.
The Company further acknowledges that its obligation to issue the Conversion Shares upon conversion of the Notes in accordance
with this Agreement and the Notes is absolute and unconditional, regardless of the dilutive effect that such issuance may have
on the ownership interests of other stockholders of the Company.

 

    	 	7	 

     

    

 

(j)            Application
of Takeover Protections; Rights Agreement. The Company and its board of directors have taken all necessary action, if any,
in order to render inapplicable any control share acquisition, interested stockholder, business combination, poison pill (including,
without limitation, any distribution under a rights agreement) or other similar anti-takeover provision under the Certificate of
Incorporation, Bylaws or other organizational documents which is or could become applicable to any Buyer as a result of the consummation
of the transactions contemplated by this Agreement, including, without limitation, the Company’s issuance of the Securities
and any Buyer’s ownership of the Securities. The Company and its board of directors have taken all necessary action, if any,
in order to render inapplicable any stockholder rights plan or similar arrangement relating to accumulations of beneficial ownership
of shares of Common Stock or a change in control of the Company.

 

(k)           Placement
Documents; Financial Statements. The Private Placement Memorandum provided to the Buyers in connection with the sale of the
Notes, at the time of the date thereon, as it may be amended from time to time, did not contain any untrue statement of a material
fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the
light of the circumstances under which they were made, not misleading. The financial statements, including the notes thereto, included
in the Private Placement Memo fairly present the financial position and the results of operations of the Company at the dates and
for the periods to which they apply; and such financial statements have been prepared in conformity with generally accepted accounting
principles, consistently applied throughout the periods involved. No other information provided by or on behalf of the Company
to any of the Buyers taken together with such Private Placement Memorandum contains any untrue statement of a material fact or
omits to state any material fact necessary in order to make the statements therein not misleading, in the light of the circumstance
under which they are or were made.

 

(l)            Absence
of Certain Changes. Since the date of the Company’s most recent financial statements contained in the Private Placement
Memorandum provided to the Buyers in connection with the sale of the Notes, there has been no material adverse change and no material
adverse development in the business, assets, liabilities, properties, operations (including results thereof) or condition (financial

dividends (whether by cash, property or securities), (ii) sold any assets, individually or in the aggregate, outside of the ordinary
course of business or (iii) made any capital expenditures, individually or in the aggregate, outside of the ordinary course of
business. The Company has not taken any steps to seek protection pursuant to any law or statute relating to bankruptcy, insolvency,
reorganization, receivership, liquidation or winding up, nor does the Company have any knowledge or reason to believe that any
of its creditors intend to initiate involuntary bankruptcy proceedings or any actual knowledge of any fact which would reasonably
lead a creditor to do so. The Company is not as of the date hereof, and after giving effect to the transactions contemplated hereby
to occur at the Closing, will not be Insolvent (as defined below). “Insolvent” means (i) the present fair saleable
value of the Company’s assets is less than the amount required to pay the Company’s total Indebtedness (as defined
below) as it becomes due, (ii) the Company is unable to pay its debts and liabilities, subordinated, contingent or otherwise, as
such debts and liabilities become absolute and matured or (iii) the Company intends to incur or believe that it will incur debts
that would be beyond its ability to pay as such debts mature.

3(n) attached to the Disclosure Letter, the Company possess all certificates, authorizations and permits issued by the appropriate
regulatory authorities necessary to conduct their respective businesses, except where the failure to possess such certificates,
authorizations or permits would not have, individually or in the aggregate, a Material Adverse Effect, and the Company has not
received any notice of proceedings relating to the revocation or modification of any such certificate, authorization or permit.

 

(o)           Foreign
Corrupt Practices. The Company and none of its directors, officers, agents, employees or other Persons acting on behalf of

consistently applied for the periods covered thereby, is classified as a capital lease (in accordance with generally accepted accounting
principles as in effect on the Closing Date), (G) all indebtedness referred to in clauses (A) through (F) above secured by (or
for which the holder of such Indebtedness has an existing right, contingent or otherwise, to be secured by) any mortgage, lien,

to in clauses (A) through (G) above. “Contingent Obligation” means, as to any Person, any direct or indirect
liability, contingent or otherwise, of that Person with respect to any indebtedness, lease, dividend or other obligation of another
Person if the primary purpose or intent of the Person incurring such liability, or the primary effect thereof, is to provide assurance

of Litigation. Except as set forth on Schedule 3(t) attached to the Disclosure Letter, there is no action, suit, proceeding,
inquiry or investigation before or by any court, public board, government agency, self-regulatory organization or body pending

respect to their services to the Company or material to the Company; or (ii) that questions the validity of this Agreement or the
right of the Company to enter into this Agreement or to consummate the transactions contemplated hereby. There has not been, and

Except as set forth in Schedule 3(u) attached to the Disclosure Letter, the Company is insured by insurers of recognized
financial responsibility against such losses and risks and in such amounts as management of the Company believes to be prudent
and customary in the businesses in which the Company is engaged. The Company has not been refused any insurance coverage sought
or applied for, and the Company has no any reason to believe that it will be unable to renew its existing insurance coverage as
and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business
at a cost that would not have a Material Adverse Effect.

 

(v)           Employee
Relations. The Company is not a party to any collective bargaining agreement and does not employ any member of a union. No
executive officer (as defined in Rule 501(f) promulgated under the 1933 Act) or other key employee of the Company has notified

of any material term of any employment contract, confidentiality, disclosure or proprietary information agreement, non-competition
agreement, or any other contract or agreement or any restrictive covenant, and the continued employment of each such executive
officer or other key employee (as the case may be) does not subject the Company to any liability with respect to any of the foregoing
matters. The Company is in compliance with all federal, state, local and foreign laws and regulations respecting labor, employment
and employment practices and benefits, terms and conditions of employment and wages and hours, except where failure to be in compliance
would not, either individually or in the aggregate, reasonably be expected to result in a Material Adverse Effect.

 

(w)           Title.
The Company has good and marketable title to all personal property owned by it which is material to the business of the Company,

and do not interfere with the use made and proposed to be made of such property by the Company.

as presently proposed to be conducted. None of the Company’s Intellectual Property Rights have expired, terminated or been
abandoned, or are expected to expire, terminate or be abandoned, within three years from the date of this Agreement. The Company

state, local or foreign laws relating to pollution or protection of human health or the environment (including, without limitation,
ambient air, surface water, groundwater, land surface or subsurface strata), including, without limitation, laws relating to emissions,

Status. After the date the Company becomes subject to the periodic reporting requirements under Sections 13 or 15(d) of the
1934 Act, as amended from time to time, together with the regulations promulgated thereunder (a “Reporting Company”),
and until the date on which the Buyers shall have sold all of the Registrable Securities (such period, to end in any event, whether
or not such securities have been sold, not later than five years after such date, the “Reporting Period”), the
Company shall use commercially reasonable efforts to timely file all reports required to be filed with the SEC pursuant to the
1934 Act, and the Company shall not terminate its status as an issuer required to file reports under the 1934 Act even if the 1934
Act or the rules and regulations thereunder would no longer require or otherwise permit such termination unless such termination
is approved by the holders of a majority stockholders of the voting power of the Company, or unless no Buyer has demand registration
rights under the Registration Rights Agreement or unless no Buyer is a holder of record of Conversion Shares (collectively, the
“Termination Conditions”).

 

(d)           Use
of Proceeds. The Company shall use the proceeds from the sale of the Securities for general corporate purposes as set forth

affiliates.

 

(e)           [Reserved.]

 

(f)            Listing.
If the Company becomes a Reporting Company, the Company shall in connection with any proper demand for registration of Registrable
Securities under the Registration Rights Agreement (if the same has not previously occurred) promptly secure the listing or designation
for quotation (as the case may be) of all of the Registrable Securities upon each national securities exchange and automated quotation
system, if any, upon which the Common Stock is then listed or designated for quotation (as the case may be) (subject to official
notice of issuance) and shall thereafter maintain such listing or designation for quotation (as the case may be) of all Registrable
Securities from time to time issuable under the terms of the Transaction Documents on such national securities exchange or automated
quotation system unless one of the Termination Conditions has occurred. During any period that the Common Stock is listed or designated,
the Company shall use commercially reasonable efforts to maintain the Common Stock’s listing or designation for quotation
(as the case may be) on The New York Stock Exchange, the NYSE MKT, the Nasdaq Global Select Market, the Nasdaq Global Market or
the Nasdaq Capital Market (each, an “Eligible Market”). During the Reporting Period, the Company shall use commercially
reasonable efforts not to take any action which could be reasonably expected to prevent a listing or result in the delisting or
suspension of the Common Stock from an Eligible Market. The Company shall pay all fees and expenses in connection with satisfying
its obligations under this Section 4(f).

 

(g)           Fees.
The Company shall be responsible for the payment of any placement agent’s fees, financial advisory fees, or broker’s
commissions (other than for Persons engaged by any Buyer) relating to or arising out of the transactions contemplated hereby and
resulting from the retention by the Company of any placement agent, financial advisor or broker (including, without limitation,
any fees payable to the Placement Agent, who is the Company’s sole placement agent in connection with the transactions contemplated
by this Agreement). Except where Buyer has breached Section 2(k) hereof, the Company shall pay, and hold each Buyer harmless against,
any liability, loss or expense (including, without limitation, reasonable attorneys’ fees and out-of-pocket expenses) arising
in connection with any claim relating to any such payment. Except as otherwise set forth in the Transaction Documents, each party
to this Agreement shall bear its own expenses in connection with the sale of the Securities to the Buyers.

 

    	 	17	 

     

    

 

(h)           Pledge
of Securities. Notwithstanding anything to the contrary contained in this Agreement, the Company acknowledges and agrees that
the Securities may be pledged by a Buyer in connection with a bona fide margin agreement or other bona fide loan or financing arrangement
that is secured by the Securities. The pledge of Securities shall not be deemed to be a transfer, sale or assignment of the Securities
hereunder, and no Buyer making a pledge of Securities shall be required to provide the Company with any notice thereof or otherwise
make any delivery to the Company pursuant to this Agreement or any other Transaction Document. The Company hereby agrees to execute
and deliver such documentation as a holder of the Securities may reasonably request in connection with a pledge of the Securities
to such pledgee by a Buyer.

 

(i)            Reservation
of Shares. The Company will take all action necessary to at all times have authorized, and reserved for the purpose of issuance,
no less than one hundred ten percent (110%) of the maximum number of Conversion Shares issuable upon conversion of the Notes.

 

(j)            Conduct
of Business. So long as any of the Securities are held by the Buyers and their successors in interest and assigns, the business
of the Company shall not be conducted in violation of any law, ordinance or regulation of any governmental entity, except where
such violations would not result, either individually or in the aggregate, in a Material Adverse Effect.

 

(k)           Subsequent
Placements. Except as set forth on Schedule 4(k) attached to the Disclosure Letter, so long as the Notes are outstanding,
the Company shall, without the prior written consent of the Required Buyers (as defined below), be prohibited from effecting or
entering into an agreement to effect any offering or placement of equity or equity linked securities or debt of the Company (“Subsequent
Placement”), other than (i) a firm commitment underwritten initial public offering through a registered broker-dealer
(an “IPO”); (ii) prior to the “IPO Outside Date” (as defined in the Senior Secured Convertible
Notes), with LVP’s prior written consent, a Subsequent Placement (or series of Subsequent Placements) in which in the aggregate
gross proceeds to the Company do not exceed $2 million; (iii) prior to the IPO Outside Date, without the consent of LVP, a Subsequent
Placement (or series of Subsequent Placements) to one or more of the Company’s industry partners and/or customers (including,
without limitation, an Original Equipment Manufacturer, Integrated Device Manufacturer, and/or foundry) in a transaction, the principal
purpose of which is not to raise equity capital; or (iv) shares of Common Stock or Convertible Securities issued to employees or
directors of, or consultants or advisors to, the Company or any of its subsidiaries pursuant to its Stock Incentive Plan (as defined
below).

 

(l)            Change
of Control. Prior to the IPO Outside Date, the Company may not effect a Specified Change of Control without the prior written
consent of the Required Buyers. “Specified Change in Control” means (x) the acquisition of the Company
by another entity by means of any transaction to which the Company is a party (including, without limitation, any merger or consolidation)
that contemplates an enterprise value of the Company of less than $75 million, or (y) a sale of all or substantially all of the
assets of the Company for an aggregate purchase price of less than $75 million (including, for purposes of this section, the sale
or exclusive license of intellectual property rights which, in the aggregate, constitutes substantially all of the corporation’s
material intellectual property assets).

 

    	 	18	 

     

    

 

(m)           Variable
Rate Transaction. Notwithstanding anything in this Agreement to the contrary, until the later of (i) none of the Notes being
outstanding or (ii) three years after the Company becomes a Reporting Company, the Company shall be prohibited from effecting or
entering into any Subsequent Placement involving a Variable Rate Transaction. “Variable Rate Transaction”
means a transaction in which the Company (i) issues or sells any Convertible Securities either (A) at a conversion, exercise or
exchange rate or other price that is based upon and/or varies with the trading prices of, or quotations for, the shares of Common
Stock at any time after the initial issuance of such Convertible Securities, or (B) with a conversion, exercise or exchange price
that is subject to being reset at some future date after the initial issuance of such Convertible Securities or upon the occurrence
of specified or contingent events directly or indirectly related to the business of the Company or the market for the Common Stock,
other than pursuant to a customary “weighted average” anti-dilution provision or in connection with any stock dividend,
stock split, combination or other similar recapitalization or (ii) enters into any agreement (including, without limitation, an
“equity line of credit” or an “at the market offering”) whereby the Company may sell securities at a future
determined price (other than standard and customary “preemptive” or “participation” rights). The Buyers,
by action of the Required Buyers, shall be entitled to obtain injunctive relief against the Company to preclude any such issuance,
which remedy shall be in addition to any right to collect damages.

 

(n)           Passive
Foreign Investment Company. For the period ending on the third year anniversary after the Company becomes a Reporting Company,
the Company shall conduct its business in such a manner as will ensure that the Company will not be deemed to constitute a passive
foreign investment company within the meaning of Section 1297 of the U.S. Internal Revenue Code of 1986, as amended.

 

(o)           Restriction
on Redemption and Cash Dividends. So long as any Notes are outstanding, the Company shall not, directly or indirectly, redeem
(other than repurchases of stock from former employees, advisors, directors, consultants or other persons who provided services
on behalf of the Company or a Subsidiary at the original purchase price thereof), or declare or pay any cash dividend or distribution
on, any securities of the Company without the prior express written consent of the Required Buyers.

 

(p)           Corporate
Existence. So long as any Notes are outstanding, the Company shall maintain its corporate existence.

 

(q)           [Reserved.]

 

(r)            [Reserved.]

 

(s)           Incentive
Equity. The Company will take the necessary actions to amend its stock incentive plan (the “Stock Incentive Plan”)
to provide that the number of shares of Common Stock reserved for issuance thereunder, together with any stock that may be awarded
for performance bonuses related to a successful IPO, shall equal to no more than fifteen percent (15%) of the number of fully diluted
shares of Common Stock (based on an assumed conversion price of the Notes (including the 2015 Convertible Notes) of $6.60) during
the period up to and including the date of the IPO and giving effect to the IPO and debt conversions triggered by the IPO, unless
otherwise mutually agreed between the Company and LVP in writing. From and after the Effective Date and through and including the
consummation of the IPO, the Company shall not issue any options or other equity awards under the Stock Incentive Plan or otherwise
to any employee, officer or director of the Company as of the Effective Date, except as disclosed in the Private Placement Memorandum,
unless otherwise mutually agreed between the Company and LVP in writing.

(t)            [Reserved.]

 

(u)           Lock-Up.
In connection with any IPO, the Company will use its best efforts to obtain lock-up agreements in a form reasonably acceptable
to the Placement Agent from the persons indicated in the below tables, covering themselves and their affiliates, in respect of
the securities issued by the Company held at the commencement of the IPO of the Company, including any common stock into which
those securities may be converted, exercised or exchanged into shares of Common Stock, for the time periods as indicated in the
below tables (for clarity, the lock-up does not apply to any of the securities to be offered to the public in the IPO through an
underwriter or selling group member or any securities acquired in the public market in, or at any time after, the IPO):

 

(A) 365 Day Lock-Up Table

 

For the period commencing on the offering
date of the IPO of the Company and extending for 365 days thereafter:

 

		·	Officers and directors serving in such capacities at the commencement of the IPO (for clarity,
if any director and officer who executed a formal lock-up agreement for a 365 day lock-up period is no longer a director or officer
at the time of the IPO, such person will be fully released from the agreement at the time of the IPO, provided that they execute
a substitute lock-up agreement as provided below under the terms of the General Lock Up Table); and

		·	The Placement Agent, provided, however the Placement Agent or its affiliates may exercise their
respective warrants to convert them into shares of Common Stock during the 365 day lock-up period.

For the period commencing on the offering
date of the IPO of the Company and extending thereafter as indicated below:

 

		·	All Employees (other than officers);

Under the General Lock-Up, those persons
named above will be prohibited from offering, selling, transferring directly or indirectly, pledging, or offering to do any of
the same directly or indirectly, any of the securities of the Company (including any securities convertible, exercisable or exchangeable
into shares of Common Stock), for a period of 180 days following the effective date of the registration statement for the IPO (the
“IPO Commencement Date”), and on the 181st day following the IPO Commencement Date and on every subsequent
31st day thereafter, 15% of the securities shall be released from the General Lock-Up until the 366th day
following the IPO Commencement Date when all such prohibitions shall have been removed. For purpose of clarity, below is a summary
of the lock-up period.

any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend
or otherwise transfer or dispose of any shares of Common Stock or any securities convertible into or exercisable or exchangeable
for Common Stock, whether now owned or hereafter acquired or with respect to which such Buyer has or hereafter acquires the power
of disposition, other than any of the securities to be offered to the public in the IPO through an underwriter or selling group
member or any securities acquired in the public market in, or at any time after, the IPO (collectively, “Restricted Stock”);
or (ii) enter into any swap or other agreement, arrangement or transaction that transfers to another, in whole or in part, directly
or indirectly, any of the economic consequence of ownership of any Restricted Stock, whether any transaction described in clause
(i) or (ii) is to be settled by delivery of Common Stock, other securities, in cash or otherwise, without the prior written consent
of the managing or lead underwriter of such offering; provided, however that, (A) on the 181st day following the IPO
Commencement Date and on every subsequent 31st day thereafter, 15% of the securities shall be released from this lock-up
provision until the 366th day following the date of the IPO Commencement Date when all such prohibitions shall have
been removed (for purpose of clarity, the table below contains a summary of the lock-up period); and (B) notwithstanding the foregoing,
if during the last seventeen (17) days of the one hundred eighty (180) day period following the IPO Commencement Date (the “FINRA

occurs, or prior to the expiration of the FINRA Restricted Period the Company announces that it will release earnings results during
the sixteen (16) day period beginning on the last day of the restricted period, then, upon the request of the managing or lead
underwriter, to the extent required by any FINRA rules, the restrictions imposed by this Section 4(v) shall continue to apply until
the end of the third (3rd) trading day following the expiration of the fifteen (15) day period beginning on the issuance
of the earnings release or the occurrence of the material news or material event. In order to enforce the restrictions agreed to
by Buyer in this Section 4(v), the Company may impose stop-transfer instructions with respect to any security acquired under or
subject to this Agreement until the end of the Restricted Period. The Company’s underwriters shall be third-party beneficiaries
of the restrictions set forth in this Section 4(v).

Commitment. The Company shall use its best efforts to file with the SEC a registration statement on Form S-1 (or any successor
form thereto) to register and sell Common Stock in an IPO (the “IPO Registration Statement”) by no later than
December 31, 2016. In the event that the Company has not filed the IPO Registration Statement with the SEC within five (5) months
of the Closing Date, then the Company shall not file the IPO Registration Statement with the SEC until at least six (6) months
and one (1) day after the Closing Date.

 

5.           REGISTER;
TRANSFER AGENT INSTRUCTIONS; LEGEND.

 

(a)           Register.
The Company shall maintain at its principal executive offices (or such other office or agency of the Company as it may designate
by notice to each holder of Securities), a register for the Notes and, if issued, the Conversion Shares in which the Company shall
record the name and address of the Person in whose name the Notes and/or Conversion Shares have been issued (including the name
and address of each transferee), the principal amount of the Notes or aggregate number of Conversion Shares held by such Person,
and any tax related information required to be maintained. The Company shall keep the register open and available at all times
during business hours for inspection of any Buyer or its legal representatives.

 

    	 	22	 

     

    

 

(b)           Transfer
Agent Instructions. If a Buyer effects a sale, assignment or transfer of the Conversion Shares in compliance with all applicable
securities laws, the Company shall permit the transfer and shall promptly issue, or shall promptly instruct its transfer agent
to issue, as applicable, one or more certificates or, if the Conversion Shares are eligible for legend removal under Section 5(d),
credit shares to the applicable balance accounts at the Depository Trust Company (“DTC”) in such name and in
such denominations as specified by such Buyer to effect such sale, transfer or assignment. In the event that such sale, assignment
or transfer involves Conversion Shares sold, assigned or transferred pursuant to an effective registration statement or in compliance
with Rule 144, the transfer agent shall issue such shares to such Buyer, assignee or transferee (as the case may be) without any
restrictive legend in accordance with Section 5(d) below. The Company acknowledges that a breach by it of its obligations under
this Section 5(b) will cause irreparable harm to each Buyer. Accordingly, the Company acknowledges that the remedy at law for a
breach of its obligations under this Section 5(b) will be inadequate and agrees, in the event of a breach or threatened breach
by the Company of the provisions of this Section 5(b), that each Buyer shall be entitled, in addition to all other available remedies,
to an order and/or injunction restraining any breach and requiring immediate issuance and transfer, without the necessity of showing
economic loss and without any bond or other security being required. The Company shall cause its counsel to issue the legal opinion
referred to in the Irrevocable Transfer Agent Instructions to the Company’s transfer agent on each Effective Date (as defined
and provided in the Registration Rights Agreement), provided that the applicable Buyer(s) or its or their representatives and/or
brokers have provided the documentation to counsel reasonably necessary or required for the basis of such legal opinion. Any fees
(with respect to the transfer agent, counsel to the Company or otherwise) associated with the issuance of such opinion or the removal
of any legends on any of the Securities shall be borne by the Company.

 

(c)           Legends.
Each Buyer understands that the Securities have been issued (or will be issued in the case of the Conversion Shares) pursuant to
an exemption from registration or qualification under the 1933 Act and applicable state securities laws, and except as set forth
below, the Securities shall bear any legend as required by the “Blue Sky” laws of any state and a restrictive legend
in substantially the following form (and a stop-transfer order may be placed against transfer of such Securities):

 

[NEITHER THE ISSUANCE AND SALE
OF THE SECURITIES REPRESENTED HEREBY NOR THE SECURITIES INTO WHICH THESE SECURITIES ARE CONVERTIBLE HAVE BEEN]/[THE SECURITIES
REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN] REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES
LAWS. THE SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED (I) IN THE ABSENCE OF (A) AN EFFECTIVE REGISTRATION
STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR (B) AN OPINION OF COUNSEL TO THE HOLDER (IF REQUESTED
BY THE COMPANY), IN A FORM REASONABLY ACCEPTABLE TO THE COMPANY, THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT OR (II) UNLESS
SOLD OR ELIGIBLE TO BE SOLD PURSUANT TO RULE 144 OR RULE 144A UNDER SAID ACT. NOTWITHSTANDING THE FOREGOING, THE SECURITIES MAY
BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN OR FINANCING ARRANGEMENT SECURED BY THE SECURITIES.

 

    	 	23	 

     

    

 

(d)           Removal
of Legends. Certificates evidencing Securities shall not be required to contain the legend set forth in Section 5(c) above
or any other legend (i) following any sale of such Securities pursuant to an effective registration statement covering the resale
of such Securities is effective under the 1933 Act, (ii) following any sale of such Securities pursuant to Rule 144, (iii) if such
Securities are eligible to be sold, assigned or transferred under Rule 144(b)(1) (provided that a Buyer provides the Company with
reasonable assurances that such Securities are eligible and will remain for sale, assignment or transfer under Rule 144(b)(1) which
shall not include an opinion of counsel), (iv) in connection with a sale, assignment or other transfer (other than under Rule 144),
provided that such Buyer provides the Company with an opinion of counsel to such Buyer, in a generally acceptable form, to the
effect that such sale, assignment or transfer of the Securities may be made without restrictive legends and thereafter made without
registration under the applicable requirements of the 1933 Act, or (v) if such legend is not required under applicable requirements
of the 1933 Act (including, without limitation, controlling judicial interpretations and pronouncements issued by the SEC, provided
that Buyer provides the Company with an opinion of counsel to such effect). If the Company is a Reporting Company and a legend
is not required pursuant to the foregoing, the Company, at its expense, shall no later than three (3) Business Days following the
delivery by a Buyer to the Company or the transfer agent (with notice to the Company) of a legended certificate representing such
Securities (endorsed or with stock powers attached, signatures guaranteed, and otherwise in form necessary to affect the reissuance
and/or transfer, if applicable), together with any other deliveries from such Buyer as may be required above in this Section 5(d),
as directed by such Buyer, either: (A) provided that the Company’s transfer agent is participating in the DTC Fast Automated
Securities Transfer Program and such Securities are Conversion Shares, credit the aggregate number of shares of Common Stock to
which such Buyer shall be entitled to the balance account of such Buyer or the purchaser of such Conversion Shares, as the case
may be (the “Designated Recipient”) with the DTC through its Deposit/Withdrawal at Custodian system or (B) if
the Company’s transfer agent is not participating in the DTC Fast Automated Securities Transfer Program, issue and dispatch
for delivery (via reputable overnight courier) to such Designated Recipient, a certificate representing such Securities that is
free from all restrictive and other legends, registered in the name of such Designated Recipient (the date by which such credit
is so required to be made to the balance account of such Designated Recipient with DTC or such certificate is required to be delivered
to such Designated Recipient pursuant to the foregoing is referred to herein as the “Required Delivery Date”).

 

    	 	24	 

     

    

 

(e)           Failure
to Timely Deliver; Buy-In. If the Company is a Reporting Company and the Company improperly fails to (i) issue and dispatch
for delivery (or cause to be so dispatched) to a Designated Recipient by the Required Delivery Date a certificate representing
the Securities so delivered to the Company by such Buyer that is free from all restrictive and other legends or (ii) credit the
balance account of such Designated Recipient’s or such Designated Recipient’s nominee with DTC for such number of Conversion
Shares so delivered to the Company, and if on or after the business day immediately following the Required Delivery Date such Buyer
(or any other Person in respect, or on behalf, of such Buyer) purchases (in an open market transaction or otherwise) shares of
Common Stock to deliver in satisfaction of a sale by such Buyer of all or any portion of the number of shares of Common Stock,
or a sale of a number of shares of Common Stock equal to all or any portion of the number of shares of Common Stock, that such
Buyer so anticipated receiving from the Company without any restrictive legend (the “Buy-In Shares”), then the
Company shall, within five (5) Business Days after such Buyer’s request and in such Buyer’s sole discretion, either
(x) pay cash to such Buyer in an amount equal to such Buyer’s total purchase price (including brokerage commissions and other
out of pocket expenses, if any) for such Buy-In Shares (the “Buy-In Price”), at which point the Company’s
obligation to so deliver such certificate or credit such Designated Recipient’s balance account shall terminate and such
shares shall be cancelled, or (y) promptly honor its obligation to so deliver to such Designated Recipient a certificate or certificates
or credit such Designated Recipient’s DTC account representing such number of shares of Common Stock that would have been
so delivered if the Company timely complied with its obligations hereunder and pay cash to such Buyer in an amount equal to the
excess (if any) of the Buy-In Price over the product of (A) such number of shares of Conversion Shares that the Company was required
to deliver to such Designated Recipient by the Required Delivery Date multiplied by (B) the lowest closing sale price of the Common
Stock on the Business Days during the period commencing on the date of the delivery by such Designated Recipient to the Company
of the applicable Conversion Shares and ending on the date of such delivery and payment under this clause (y).

written agreement of the Buyers and the Company; or

either the Company or a Buyer (as to itself but no other Buyer) upon written notice to the other, if the Closing shall not have

8(a)(ii) shall not be available to any party whose failure to comply with its obligations under this Agreement has been the cause
of or resulted in the failure of the Closing to occur on or before such time.

 

    	 	28	 

     

    

 

(b)           No
termination of this Agreement shall affect any obligation of the Company under this Agreement to reimburse such Buyer for the expenses
described in Section 4(g) above. Nothing contained in this Section 8 shall be deemed to release any party from any liability for
any breach by such party of the terms and provisions of this Agreement or the other Transaction Documents or to impair the right
of any party to compel specific performance by any other party of its obligations under this Agreement or the other Transaction
Documents.

 

9.           MISCELLANEOUS.

 

(a)           Governing
Law; Jurisdiction; Jury Trial. All questions concerning the construction, validity, enforcement and interpretation of this
Agreement shall be governed by the internal laws of the State of New York, without giving effect to any choice of law or conflict
of law provision or rule (whether of the State of New York or any other jurisdictions) that would cause the application of the
laws of any jurisdictions other than the State of New York. Each party hereby irrevocably submits to the exclusive jurisdiction
of the state and federal courts sitting in The City of New York, Borough of Manhattan, for the adjudication of any dispute hereunder
or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees
not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court,
that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such suit, action or proceeding is
improper. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit,
action or proceeding by mailing a copy thereof to such party at the address for such notices to it under this Agreement and agrees
that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be
deemed to limit in any way any right to serve process in any manner permitted by law. Nothing contained herein shall be deemed
or operate to preclude any Buyer from bringing suit or taking other legal action against the Company in any other jurisdiction
to collect on the Company’s obligations to such Buyer or to enforce a judgment or other court ruling in favor of such Buyer.
EACH PARTY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE TO, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION
OF ANY DISPUTE HEREUNDER OR IN CONNECTION WITH OR ARISING OUT OF THIS AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREBY.

 

(b)           Counterparts.
This Agreement may be executed in two or more identical counterparts, all of which shall be considered one and the same agreement
and shall become effective when counterparts have been signed by each party and delivered to the other party. In the event that
any signature is delivered by facsimile transmission or by an e-mail which contains a portable document format (.pdf) file of an
executed signature page, such signature page shall create a valid and binding obligation of the party executing (or on whose behalf
such signature is executed) with the same force and effect as if such signature page were an original thereof.

 

    	 	29	 

     

    

 

(c)           Headings;
Gender. The headings of this Agreement are for convenience of reference and shall not form part of, or affect the interpretation
of, this Agreement. Unless the context clearly indicates otherwise, each pronoun herein shall be deemed to include the masculine,
feminine, neuter, singular and plural forms thereof. The terms “including,” “includes,” “include”
and words of like import shall be construed broadly as if followed by the words “without limitation.” The terms “herein,”
“hereunder,” “hereof” and words of like import refer to this entire Agreement instead of just the provision
in which they are found.

 

(d)           Severability.
If any provision of this Agreement is prohibited by law or otherwise determined to be invalid or unenforceable by a court of competent
jurisdiction, the provision that would otherwise be prohibited, invalid or unenforceable shall be deemed amended to apply to the
broadest extent that it would be valid and enforceable, and the invalidity or unenforceability of such provision shall not affect
the validity of the remaining provisions of this Agreement so long as this Agreement as so modified continues to express, without
material change, the original intentions of the parties as to the subject matter hereof and the prohibited nature, invalidity or
unenforceability of the provision(s) in question does not substantially impair the respective expectations or reciprocal obligations
of the parties or the practical realization of the benefits that would otherwise be conferred upon the parties. The parties will
endeavor in good faith negotiations to replace the prohibited, invalid or unenforceable provision(s) with a valid provision(s),
the effect of which comes as close as possible to that of the prohibited, invalid or unenforceable provision(s). Notwithstanding
anything to the contrary contained in this Agreement or any other Transaction Document (and without implication that the following
is required or applicable), it is the intention of the parties that in no event shall amounts and value paid by the Company, or
payable to or received by any of the Buyers, under the Transaction Documents (including without limitation, any amounts that would
be characterized as “interest” under applicable law) exceed amounts permitted under any applicable law. Accordingly,
if any obligation to pay, payment made to any Buyer, or collection by any Buyer pursuant the Transaction Documents is finally judicially
determined to be contrary to any such applicable law, such obligation to pay, payment or collection shall be deemed to have been
made by mutual mistake of such Buyer, and the Company and such amount shall be deemed to have been adjusted with retroactive effect
to the maximum amount or rate of interest, as the case may be, as would not be so prohibited by the applicable law. Such adjustment
shall be effected, to the extent necessary, by reducing or refunding, at the option of such Buyer, the amount of interest or any
other amounts which would constitute unlawful amounts required to be paid or actually paid to such Buyer under the Transaction
Documents. For greater certainty, to the extent that any interest, charges, fees, expenses or other amounts required to be paid
to or received by such Buyer under any of the Transaction Documents or related thereto are held to be within the meaning of “interest”
or another applicable term to otherwise be violative of applicable law, such amounts shall be pro-rated over the period of time
to which they relate.

 

    	 	30	 

     

    

 

(e)          Entire
Agreement; Amendments. This Agreement, the other Transaction Documents and the schedules and exhibits attached hereto and thereto
and the instruments referenced herein and therein supersede all other prior oral or written agreements between the Buyers, the
Company, their affiliates and Persons acting on their behalf solely with respect to the matters contained herein and therein, and
this Agreement, the other Transaction Documents, the schedules and exhibits attached hereto and thereto and the instruments referenced
herein and therein contain the entire understanding of the parties solely with respect to the matters covered herein and therein;
provided, however, except as explicitly stated herein, nothing contained in this Agreement or any other Transaction Document shall
(or shall be deemed to) (i) have any effect on any agreements any Buyer has entered into with, or any instruments any Buyer has
received from, the Company prior to the date hereof with respect to any prior investment made by such Buyer in the Company or (ii)
waive, alter, modify or amend in any respect any obligations of the Company, or any rights of or benefits to any Buyer or any other
Person, in any agreement entered into prior to the date hereof between or among the Company and any Buyer, or any instruments any
Buyer received from the Company prior to the date hereof, and all such agreements and instruments shall continue in full force
and effect. Except as specifically set forth herein or therein, neither the Company nor any Buyer makes any representation, warranty,
covenant or undertaking with respect to such matters. For clarification purposes, the Recitals are part of this Agreement. No provision
of this Agreement may be amended other than by an instrument in writing signed by the Company and the Required Buyers. Any amendment
to any provision of this Agreement made in conformity with the provisions of this Section 9(e) shall be binding on all Buyers and
holders of Securities, as applicable, provided that no such amendment shall be effective to the extent that it (1) applies to less
than all of the holders of the Securities then outstanding or (2) imposes any obligation or liability on any Buyer without such
Buyer’s prior written consent (which may be granted or withheld in such Buyer’s sole discretion). No waiver shall be
effective unless it is in writing and signed by an authorized representative of the waiving party, provided that the Required Buyers
may waive any provision of this Agreement, and any waiver of any provision of this Agreement made in conformity with the provisions
of this Section 9(e) shall be binding on all Buyers and holders of Securities, as applicable, provided that no such waiver shall
be effective to the extent that it (1) applies to less than all of the holders of the Securities then outstanding (unless a party
gives a waiver as to itself only) or (2) imposes any obligation or liability on any Buyer without such Buyer’s prior written
consent (which may be granted or withheld in such Buyer’s sole discretion). No consideration shall be offered or paid to
any Person to amend or consent to a waiver or modification of any provision of any of the Transaction Documents unless the same
consideration also is offered to all of the parties to the Transaction Documents who are holders of Notes. The Company has not,
directly or indirectly, made any agreements with any Buyers relating to the terms or conditions of the transactions contemplated
by the Transaction Documents except as set forth in the Transaction Documents. Without limiting the foregoing, the Company confirms
that, except as set forth in this Agreement, no Buyer has made any commitment or promise or has any other obligation to provide
any financing to the Company or otherwise. As a material inducement for each Buyer to enter into this Agreement, the Company expressly
acknowledges and agrees that no due diligence or other investigation or inquiry conducted by a Buyer, any of its advisors or any
of its representatives shall affect such Buyer’s right to rely on, or shall modify or qualify in any manner or be an exception
to any of, the Company’s representations and warranties contained in this Agreement or any other Transaction Document. “Required
Buyers” means Buyers holding Notes and 2015 Convertible Notes having an aggregate outstanding principal amount that represents
a majority of the aggregate outstanding principal amount of all Notes and 2015 Convertible Notes.

(g)          Successors
and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their respective successors and
assigns, including, as contemplated below, any assignee of any of the Securities. The Company shall not assign this Agreement or
any rights or obligations hereunder without the prior written consent of the Required Buyers; except in the event of a Change in
Control (as defined in the Notes) where the Company repays in full the outstanding Notes of each Buyer or offers each Buyer an
election to be repaid in full under such outstanding notes contingent only upon consummation of such Change in Control. A Buyer
may assign some or all of its rights hereunder in connection with any transfer of any of its Securities without the consent of
the Company, in which event such assignee shall be deemed to be a Buyer hereunder with respect to such assigned rights.

 

(h)          No
Third Party Beneficiaries. This Agreement is intended for the benefit of the parties hereto and their respective permitted
successors and assigns, and is not for the benefit of, nor may any provision hereof be enforced by, any other Person, other than
the Indemnitees referred to in Section 9(k).

 

(i)          Survival.
The representations, warranties, agreements and covenants shall survive the Closing and shall expire on the conversion of the Notes
into Conversion Shares. Each Buyer shall be responsible only for its own representations, warranties, agreements and covenants
hereunder.

 

(j)          Further
Assurances. Each party shall do and perform, or cause to be done and performed, all such further acts and things, and shall
execute and deliver all such other agreements, certificates, instruments and documents, as any other party may reasonably request
in order to carry out the intent and accomplish the purposes of this Agreement and the consummation of the transactions contemplated
hereby.

 

(k)          Indemnification.
In consideration of each Buyer’s execution and delivery of the Transaction Documents and acquiring the Securities thereunder
and in addition to all of the Company’s other obligations under the Transaction Documents, the Company shall defend, protect,
indemnify and hold harmless each Buyer and each holder of any Securities and all of their stockholders, partners, members, officers,
directors, employees and direct or indirect investors and any of the foregoing Persons’ agents or other representatives (including,
without limitation, those retained in connection with the transactions contemplated by this Agreement) (collectively, the “Indemnitees”)
from and against any and all actions, causes of action, suits, claims, losses, costs, penalties, fees, liabilities and damages,
and expenses in connection therewith (irrespective of whether any such Indemnitee is a party to the action for which indemnification
hereunder is sought), and including reasonable attorneys’ fees and disbursements for one (1) counsel to all the Buyers (the
“Indemnified Liabilities”), incurred by any Indemnitee as a result of, or arising out of, or relating to (a)
any misrepresentation or breach of any representation or warranty made by the Company in any of the Transaction Documents, (b)
any breach of any covenant, agreement or obligation of the Company contained in any of the Transaction Documents, or (c) any cause
of action, suit, proceeding or claim brought or made against such Indemnitee by a third party (including for these purposes a derivative
action brought on behalf of the Company) or which otherwise involves such Indemnitee that arises out of or results from (i) the
execution, delivery, performance or successful enforcement of any of the Transaction Documents, or (ii) the status of such Buyer
as a Note holder as a result of the transactions contemplated by the Transaction Documents or as a party to this Agreement (including,
without limitation, as a party in interest or otherwise in any action or proceeding for injunctive or other equitable relief).
To the extent that the foregoing undertaking by the Company may be unenforceable for any reason, the Company shall make the maximum
contribution to the payment and satisfaction of each of the Indemnified Liabilities which is permissible under applicable law.
Except as otherwise set forth herein, the mechanics and procedures with respect to the rights and obligations under this Section
9(k) shall be the same as those set forth in Section 6 of the Registration Rights Agreement. No Indemnitee shall be entitled to
indemnification under this Section 9(k) to the extent an Indemnified Liability arises out of the gross negligence or willful misconduct
of such Indemnitee. The Company shall not be obligated hereunder for any settlement entered into by an Indemnitee without the Company’s
prior written consent; provided, however, that the Company shall not unreasonably withhold, delay or condition its consent.

 

    	 	33	 

     

    

 

(l)          Construction.
The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and
no rules of strict construction will be applied against any party. No specific representation or warranty shall limit the generality
or applicability of a more general representation or warranty. Each and every reference to share prices, shares of Common Stock
and any other numbers in this Agreement that relate to the Common Stock shall be automatically adjusted for stock dividends, stock
splits, stock combinations and other similar transactions that occur with respect to the Common Stock after the date of this Agreement.

 

(m)          Remedies.
Each Person having any rights under any provision of this Agreement shall have all rights and remedies set forth in the Transaction
Documents and all rights and remedies which such holders have been granted at any time under any other agreement or contract and
all of the rights which such holders have under any law. Any Person having any rights under any provision of this Agreement shall
be entitled to enforce such rights specifically (without posting a bond or other security), to recover damages by reason of any
breach of any provision of this Agreement and to exercise all other rights granted by law. Furthermore, the Company recognizes
that in the event that it fails to perform, observe, or discharge any or all of its obligations under the Transaction Documents,
any remedy at law may prove to be inadequate relief to the Buyers. The Company therefore agrees that the Buyers shall be entitled
to seek specific performance and/or temporary, preliminary and permanent injunctive or other equitable relief from any court of
competent jurisdiction in any such case without the necessity of proving actual damages and without posting a bond or other security.

 

(n)          Withdrawal
Right. Notwithstanding anything to the contrary contained in (and without limiting any similar provisions of) the Transaction
Documents, whenever any Buyer exercises a right, election, demand or option under a Transaction Document and the Company does not
timely perform its related obligations within the periods therein provided, then such Buyer may rescind or withdraw, in its sole
discretion from time to time upon written notice to the Company, any relevant notice, demand or election in whole or in part without
prejudice to its future actions and rights.

 

    	 	34	 

     

    

 

(o)          Payment
Set Aside; Currency. To the extent that the Company makes a payment or payments to any Buyer hereunder or pursuant to any of
the other Transaction Documents or any of the Buyers enforce or exercise their rights hereunder or thereunder, and such payment
or payments or the proceeds of such enforcement or exercise or any part thereof are subsequently invalidated, declared to be fraudulent
or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the Company,
a trustee, receiver or any other Person under any law (including, without limitation, any bankruptcy law, foreign, state or federal
law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally
intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such enforcement
or setoff had not occurred. Unless otherwise expressly indicated, all dollar amounts referred to in this Agreement and the other
Transaction Documents are in United States Dollars (“U.S. Dollars”), and all amounts owing under this Agreement
and all other Transaction Documents shall be paid in U.S. Dollars. All amounts denominated in other currencies (if any) shall be
converted into the U.S. Dollar equivalent amount in accordance with the Exchange Rate on the date of calculation. “Exchange
Rate” means, in relation to any amount of currency to be converted into U.S. Dollars pursuant to this Agreement,
the U.S. Dollar exchange rate as published in The Wall Street Journal on the relevant date of calculation.

 

(p)          Independent
Nature of Buyers’ Obligations and Rights. The obligations of each Buyer under the Transaction Documents are several and
not joint with the obligations of any other Buyer, and no Buyer shall be responsible in any way for the performance of the obligations
of any other Buyer under any Transaction Document. Nothing contained herein or in any other Transaction Document, and no action
taken by any Buyer pursuant hereto or thereto, shall be deemed to constitute the Buyers as, and the Company acknowledges that the
Buyers do not so constitute, a partnership, an association, a joint venture or any other kind of group or entity, or create a presumption
that the Buyers are in any way acting in concert or as a group or entity with respect to such obligations or the transactions contemplated
by the Transaction Documents or any matters, and the Company acknowledges that the Buyers are not acting in concert or as a group,
and the Company shall not assert any such claim, with respect to such obligations or the transactions contemplated by the Transaction
Documents. The decision of each Buyer to purchase Securities pursuant to the Transaction Documents has been made by such Buyer
independently of any other Buyer. Each Buyer acknowledges that no other Buyer has acted as agent for such Buyer in connection with
such Buyer making its investment hereunder and that no other Buyer will be acting as agent of such Buyer in connection with monitoring
such Buyer’s investment in the Securities or enforcing its rights under the Transaction Documents. The Company and each Buyer
confirms that each Buyer has independently participated with the Company in the negotiation of the transaction contemplated hereby
with the advice of its own counsel and advisors. Each Buyer shall be entitled to independently protect and enforce its rights,
including, without limitation, the rights arising out of this Agreement or out of any other Transaction Documents, and it shall
not be necessary for any other Buyer to be joined as an additional party in any proceeding for such purpose. The use of a single
agreement to effectuate the purchase and sale of the Securities contemplated hereby was solely in the control of the Company, not
the action or decision of any Buyer, and was done solely for the convenience of the Company and not because it was required or
requested to do so by any Buyer. It is expressly understood and agreed that each provision contained in this Agreement and in each
other Transaction Document is between the Company and a Buyer, solely, and not between the Company and the Buyers collectively
and not between and among the Buyers.

ATOMERA
INCORPORATED

 

Senior
Secured Convertible Note

 

	Issuance Date:  April 1, 2016	Principal Amount: U.S. $_________

 

FOR VALUE RECEIVED,
Atomera Incorporated, a Delaware corporation (the “Company”), hereby promises to pay to the order of ____________
or its registered assigns (“Holder”) the amount set out above as the Principal Amount (the “Principal”)
when due, whether upon the Maturity Date (as defined below), acceleration, prepayment or otherwise (in each case in accordance
with the terms hereof) and to pay interest (“Interest”) on the outstanding Principal at the applicable Interest
Rate (as defined below) from the date set out above as the Issuance Date (the “Issuance Date”) until
the same becomes due and payable, whether upon the Maturity Date or acceleration, conversion, prepayment or otherwise (in each
case in accordance with the terms hereof). This Senior Secured Convertible Note (this “Note”) is one of an issue
of Senior Secured Convertible Notes issued either (i) pursuant to the Securities Purchase Agreement (as defined below) on the Closing
Date (as defined below); or (ii) pursuant to that certain securities purchase agreement, dated as of March 17, 2015, by and among
Atomera Incorporated (f/k/a Mears Technologies, Inc.) and the investors listed on the Schedule of Buyers attached thereto (collectively,
the “Other Notes” and together with this Note, the “Notes”). Certain capitalized terms used
herein are defined in Section 22. All other capitalized terms not defined herein shall have the meaning given to such terms in
the Securities Purchase Agreement.

 

1.          PREPAYMENT.
The Company may, at any time prior to the Maturity Date, prepay this Note in full, and in part, including all unpaid and accrued
interest thereon, provided however that the written consent of the Required Holders shall be required if prepaid before the IPO
Outside Date. In the event the Company wishes to prepay this Note on or before the IPO Outside Date, it shall notify the Holder
and the holders of the Other Notes to obtain the requisite consents. A prepayment made pursuant to this Section 1 shall be made
pro rata among all Note holders.

 

2.          INTEREST
RATE. So long as no Event of Default shall have occurred and be continuing, Interest on this Note shall accrue at a rate equal
to ten percent (10%) simple interest per annum. Interest shall be payable on the Maturity Date, or such earlier date as is required
pursuant to this Note. If an Event of Default shall have occurred and be continuing, the Interest Rate shall automatically be increased
to twelve percent (12%) simple interest during the period of such Event of Default, until such Event of Default is later cured.
Interest due on this Note shall be computed on the basis of a three hundred sixty-five (365)-day year.

 

     

     

    

 

3.          CONVERSION
OF NOTES. This Note shall be convertible into validly issued, fully paid and non-assessable shares of Common Stock (as defined
below), on the terms and conditions set forth in this Section 3. 

 

(a)          Mandatory
Conversion - IPO. Upon consummation of the IPO (as defined below), this Note shall automatically convert, through no further
action on the part of the Company or the Holder, into that number of shares of Common Stock equal to the quotient of (A) the Conversion
Amount (as defined below) divided by (B) the Conversion Price. For the purpose of this Section 3(a), the “Conversion Price”
shall be equal to fifty percent (50%) of the IPO Price to Public (as defined below) (rounded to two decimal places); provided;
however, that in no event shall the Conversion Price be greater than $7.362 or nor less than $3.681, in each case as adjusted
for stock splits, stock dividends, stock combinations, recapitalizations, or the like that occur after the Issuance Date in accordance
with Section 5.

 

(b)          Optional
Conversion – Financing. Upon consummation of a Subsequent Placement other than the IPO pursuant to Section 4(k) of the
Securities Purchase Agreement, the Holder shall be entitled to elect to convert all of the Notes into shares of Common Stock. In
the event that the Holder so elects to convert, this Note shall convert into that number of shares of Common Stock equal to the
quotient of (A) the Conversion Amount divided by (B) the Conversion Price. For the purposes of this Section 3(b), the “Conversion
Price” shall be equal to fifty percent (50%) of the purchase price of the securities being sold by the Company in such
Subsequent Placement (rounded to two decimal places); provided; however, that in no event shall the Conversion Price
be greater than $7.362 or nor less than $3.681, in each case as adjusted for stock splits, stock dividends, stock combinations,
recapitalizations, or the like that occur after the Issuance Date in accordance with Section 5. 

 

(c)          Optional
Conversion. At any time after the Issuance Date and until ten (10) calendar days prior to the consummation of the IPO, the
Holder shall be entitled to elect to convert all of this Note into shares of Common Stock. In the event that the Holder so elects
to convert, this Note shall convert into that number of shares of Common Stock equal to the quotient of (A) the Conversion Amount
divided by (B) the Conversion Price. For the purposes of this Section 3(c), the “Conversion Price” shall be
equal to $7.362, as adjusted for stock splits, stock dividends, stock combinations, recapitalizations, or the like that occur after
the Issuance Date in accordance with Section 5. 

 

(d)          Mechanics
of Conversion.

 

(i)          Conversion;
Issuance of Shares. To convert the Notes pursuant to Sections 3(b) or 3(c) above into shares of Common Stock on any date (a
“Conversion Date”), the Holder shall deliver (whether via facsimile or otherwise) a copy of a properly and fully-completed
and executed notice of conversion in the form attached hereto as Exhibit I (the “Conversion Notice”)
to the Company and to each other holder of a Note. Promptly following the date of receipt of such Conversion Notice, or, with respect
to a mandatory conversion pursuant to Section 3(a), upon the consummation of the IPO, and following the Holder’s delivery
of this original Note to the Company for cancellation, the Company shall issue and deliver (via reputable overnight courier) to
the Holder a certificate, registered in the name of the Holder or its designee, for the number of shares of Common Stock to which
the Holder shall be entitled, with the legends required by the Securities Purchase Agreement or applicable law. 

 

    	 	2	 

     

    

 

(ii)         Registration.
The Company shall maintain a register (the “Register”) for the recordation of the names and addresses of the
holders of each Note and the principal amount of the Notes held by such holders (the “Registered Notes”). The
entries in the Register shall be conclusive and binding for all purposes absent manifest error. The Company and the holders of
the Notes shall treat each Person whose name is recorded in the Register as the owner of a Note for all purposes (including, without
limitation, the right to receive payments of Principal and Interest hereunder) notwithstanding notice to the contrary. A Registered
Note may be assigned, transferred or sold in whole or in part only by registration of such assignment or sale on the Register.
Upon its receipt of a written request to assign, transfer or sell all or part of any Registered Note by the holder thereof and
subject to the holder’s compliance with Section 11, the Company shall record the information contained therein in the Register
and issue one or more new Registered Notes in the same aggregate principal amount as the principal amount of the surrendered Registered
Note to the designated assignee or transferee pursuant to Section 12, provided that if the Company does not so record an assignment,
transfer or sale (as the case may be) of all or part of any Registered Note within two (2) Business Days of its receipt of such
a request, then the Register shall be automatically updated to reflect such assignment, transfer or sale (as the case may be).
The Holder and the Company shall maintain records showing the Principal and Interest converted and/or paid (as the case may be)
and the dates of such conversion and/or payments (as the case may be) or shall use such other method, reasonably satisfactory to
the Holder and the Company, so as not to require physical surrender of this Note upon conversion.

 

(iii)        No
Fractional Shares; Transfer Taxes. The Company shall not issue any fraction of a share of Common Stock upon any conversion.
If the issuance would result in the issuance of a fraction of a share of Common Stock, the Company shall round such fraction of
a share of Common Stock up to the nearest whole share. The Company shall pay any and all transfer, stamp, issuance and similar
taxes that may be payable with respect to the issuance and delivery of Common Stock upon any conversion.

 

4.          RIGHTS
UPON EVENT OF DEFAULT.

 

(a)          Event
of Default. Each of the following events shall constitute an “Event of Default”:

 

(i)          the
Company’s failure to pay to the Holder any amount of Principal or Interest when and as due if such failure remains uncured
for a period of at least five (5) Business Days;

insolvency, reorganization or other proceedings for the relief of debtors shall be instituted against the Company and shall not

reorganization or other similar law or the consent by it to the entry of a decree, order, judgment or other similar document in
respect of the Company in an involuntary case or proceeding under any applicable federal, state or foreign bankruptcy, insolvency,
reorganization or other similar law or to the commencement of any bankruptcy or insolvency case or proceeding against it, or the
filing by it of a petition or answer or consent seeking reorganization or relief under any applicable federal, state or foreign
law, or the consent by it to the filing of such petition or to the appointment of or taking possession by a custodian, receiver,
liquidator, assignee, trustee, sequestrator or other similar official of the Company or of any substantial part of its property,
or the making by it of an assignment for the benefit of creditors, or the execution of a composition of debts, or the occurrence
of any other similar federal, state or foreign proceeding, or the admission by it in writing of its inability to pay its debts
generally as they become due, the taking of corporate action by the Company in furtherance of any such action;

 

    	 	3	 

     

    

 

(v)         the

receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or of any substantial part of its
property, or ordering the winding up or liquidation of its affairs, and the continuance of any such decree, order, judgment or
other similar document or any such other decree, order, judgment or other similar document unstayed and in effect for a period
of sixty (60) consecutive days;

 

(vi)        a
final judgment or judgments for the payment of money aggregating in excess of $250,000 are rendered against the Company and which
judgments are not, within sixty (60) days after the entry thereof, satisfied, bonded, discharged or stayed pending appeal, or are
not satisfied, bonded or discharged within sixty (60) days after the expiration of such stay; 

 

(vii)       the
Company fails to pay, when due, or within any applicable grace period, any payment with respect to any Indebtedness in excess of
$250,000 due to any third party (other than, with respect to unsecured Indebtedness only, payments contested by the Company in
good faith by proper proceedings and with respect to which adequate reserves have been set aside for the payment thereof in accordance
with GAAP) or is otherwise in breach or violation of any agreement for monies owed or owing by the Company in an amount in excess
of $250,000, which breach or violation permits the other party thereto to declare a default or otherwise accelerate amounts due
thereunder;

 

(viii)      other

or condition of any Transaction Document, if such breach remains uncured for a period of thirty (30) days after actual knowledge
of the Company of such breach, or any representation or warranty made by the Company in any Transaction Document is not accurate
in any material respect when made or deemed made;

 

(ix)         the
validity or enforceability of any provision of any Transaction Document shall be contested by the Company, or a proceeding shall
be commenced by the Company seeking to establish the invalidity or unenforceability thereof;

 

(x)          the
Security Documents shall for any reason, except (A) to the extent permitted by the terms hereof or thereof, or (B) as a result
of the act or omission of Holder or the holder of any Other Note and not materially related to the failure of the Company to satisfy
or tender to satisfy its obligations under the Security Documents, fail or cease to create a separate valid and perfected first
priority Lien on the Collateral (as defined in the Security Agreement) in favor of each of the Secured Parties (as defined in the
Security Agreement) and such breach remains uncured for a period of ten (10) Business Days after notice from Holder or the holder
of any Other Note of such failure or ceasing; or

 

    	 	4	 

     

    

 

(xi)         any
Event of Default (as defined in the Other Notes) occurs with respect to any of the Other Notes.

of an Event of Default. Upon the occurrence of an Event of Default with respect to this Note or any Other Note, the Company
shall within five (5) Business Days deliver written notice thereof via facsimile and overnight courier (with next day delivery
specified) (an “Event of Default Notice”) to the Holder. At any time after the occurrence of an Event of Default,
the Required Holders may, by notice to the Company, declare all of the Notes to be forthwith due and payable, whereupon the Principal
and all accrued and unpaid Interest thereon, plus all costs of enforcement and collection (including court costs and reasonable
attorney’s fees), shall immediately become and be forthwith due and payable, without presentment, demand, protest or further
notice of any kind, all of which are hereby expressly waived by the Company. 

 

5.          ADJUSTMENT
OF CONVERSION PRICE.

 

(a)          Adjustment
of Conversion Price Collar upon Subdivision or Combination of Common Stock. If the Company subdivides (by any stock split,
stock dividend, recapitalization or otherwise) one or more classes of its outstanding shares of Common Stock into a greater number
of shares, the Conversion Price (and the minimum and maximum amounts of the Conversion Price) in effect immediately prior to such
subdivision will be proportionately reduced. If the Company at any time combines (by combination, reverse stock split or otherwise)
one or more classes of its outstanding shares of Common Stock into a smaller number of shares, the Conversion Price (and the minimum
and maximum amounts of the Conversion Price) in effect immediately prior to such combination will be proportionately increased.
Any adjustment pursuant to this Section 5(a) shall become effective immediately after the effective date of such subdivision or
combination. 

 

(b)          Other
Events. In the event that the Company shall take any action to which the provisions of Section 5(a) are not strictly applicable,
or, if applicable, would not operate to protect the Holder from dilution or if any event occurs of the type contemplated by the
provisions of this Section 5 but not expressly provided for by such provisions, then the Company’s Board of Directors shall
in good faith determine and implement an appropriate adjustment in the Conversion Price so as to protect the rights of the Holder,
provided that no such adjustment pursuant to this Section 5(b) will increase the Conversion Price as otherwise determined pursuant
to this Section 5, provided further that if the Holder does not accept such adjustments as appropriately protecting its interests
hereunder against such dilution, then the Company’s Board of Directors and the Holder shall agree, in good faith, upon an
independent investment bank of nationally recognized standing to make such appropriate adjustments, whose determination shall be
final and binding and whose fees and expenses shall be borne by the Company.

 

    	 	5	 

     

    

 

6.          NONCIRCUMVENTION.
The Company hereby covenants and agrees that the Company will not, by amendment of its Certificate of Incorporation or Bylaws or
through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issue or sale of securities,
or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Note, and will
at all times in good faith carry out all of the provisions of this Note and take all action as may be required to protect the rights
of the Holder of this Note. Without limiting the generality of the foregoing, so long as any of the Notes remain outstanding, the
Company (i) shall not increase the par value of any shares of Common Stock receivable upon conversion of this Note above the
Conversion Price then in effect and (ii) shall take all such actions as may be necessary or appropriate in order that the
Company may validly and legally issue fully paid and non-assessable shares of Common Stock upon the conversion of this Note, including
without limitation complying with Section 7(b) hereof.

 

7.          RESERVATION
OF AUTHORIZED SHARES.

 

(a)          Reservation.
The Company shall at all times during which the Notes are outstanding reserve and keep available out of its authorized but unissued
shares Common Stock, solely for the purpose of effecting the conversion of the Notes, no less than one hundred ten percent (110%)
of the maximum number of shares issuable on conversion of the Notes (the “Required Reserve Amount”). 

 

(b)          Insufficient
Authorized Shares. If, notwithstanding Section 7(a), and not in limitation thereof, at any time while any of the Notes remain
outstanding the Company does not have a sufficient number of authorized and unreserved shares of Common Stock to satisfy its obligation
to reserve a number of shares of Common Stock equal to the Required Reserve Amount (an “Authorized Share Failure”),
then the Company shall as soon as reasonably practicable take all action within its power necessary to increase the Company’s
authorized shares of Common Stock to an amount sufficient to allow the Company to reserve the Required Reserve Amount for the Notes
then outstanding, including without limitation using its best efforts to secure necessary Board of Directors and stockholder approvals,
as further described below, to appropriately amend the Company’s Certificate of Incorporation to provide for such increase.
Without limiting the generality of the foregoing sentence, if not earlier approved by written consent of the stockholders, as soon
as practicable after the date of the occurrence of an Authorized Share Failure, but in no event later than seventy (70) days after
the occurrence of such Authorized Share Failure, the Company shall hold a meeting of its stockholders for the approval of an increase
in the number of authorized shares of Common Stock; in connection with any such meeting, the Company shall provide each stockholders
with a proxy statement and shall use its best efforts to solicit its stockholders’ approval of such increase in authorized
shares of Common Stock and to cause its Board of Directors to recommend to the stockholders that they approve such proposal.

 

8.          COVENANTS.
Until all of the Notes have been converted or otherwise satisfied in accordance with their terms:

 

(a)          Rank.
All payments due under this Note shall rank pari passu with all Other Notes. 

 

(b)          New
Subsidiaries. Simultaneously with the acquisition or formation of each New Subsidiary, other than a Foreign Subsidiary, the
Company shall cause such New Subsidiary to execute, and deliver to each holder of Notes, all joinders to, or as applicable additional,
Security Documents (as defined in the Security Agreement) as requested by the Holder. The Company shall not, directly or indirectly,
acquire or form any New Subsidiary if such New Subsidiary would not be wholly-owned, directly or indirectly, by the Company. 

 

9.          SECURITY.
This Note and the Other Notes are secured to the extent and in the manner set forth in the Transaction Documents (including, without
limitation, the Security Agreement and the other Security Documents).

 

10.         AMENDING
THE TERMS OF THIS NOTE. No provision of this Note may be amended other than by an instrument in writing signed by the Company
and the Required Holders, and any amendment to any provision of this Note made in conformity with the provisions of this Section
10 shall be binding on all Holders, provided that no such amendment shall be effective to the extent that it (1) applies to less
than all of the holders of the Notes then outstanding or (2) imposes any obligation or liability on any Holder without such Holder’s
prior written consent (which may be granted or withheld in such Holder’s sole discretion). No waiver of any provision of
this Note shall be effective unless it is in writing and signed by an authorized representative of the waiving party, provided
that the Required Holders may waive any provision of this Note, and any waiver of any provision of this Note made in conformity
with the provisions of this Section 10 shall be binding on all Holders, provided that no such waiver shall be effective to the
extent that it (1) applies to less than all of the holders of the Notes then outstanding (unless a party gives a waiver as to itself
only) or (2) imposes any obligation or liability on any Holder without such Holder’s prior written consent (which may be

This Note and any shares of Common Stock issued upon conversion of this Note (the “Conversion Shares”) may be
offered, sold, assigned or transferred by the Holder without the consent of the Company, subject only to the provisions of Section
2(g) of the Securities Purchase Agreement and any other restrictions that may be mutually agreed by the Company and the Holder
hereof. Notwithstanding anything in this Note to the contrary, neither this Note nor any Conversion Shares may be sold, assigned
or transferred by the Holder unless the recipient of such agrees in writing to be bound by the terms and conditions of the Securities
Purchase Agreement and the Registration Rights Agreement. 

 

12.         REISSUANCE
OF THIS NOTE.

 

(a)          Transfer.
If this Note is to be transferred, the Holder shall surrender this Note to the Company, whereupon the Company will forthwith issue
and deliver upon the order of the Holder a new Note (in accordance with Section 12(d)), registered as the Holder may request, representing
the outstanding Principal being transferred by the Holder and, if less than the entire outstanding Principal is being transferred,
a new Note (in accordance with Section 12(d)) to the Holder representing the outstanding Principal not being transferred. 

 

(b)          Lost,
Stolen or Mutilated Note. Upon receipt by the Company of evidence reasonably satisfactory to the Company of the loss, theft,
destruction or mutilation of this Note (as to which a written certification and the indemnification contemplated below shall suffice
as such evidence), and, in the case of loss, theft or destruction, of any indemnification undertaking by the Holder to the Company
in customary and reasonable form and, in the case of mutilation, upon surrender and cancellation of this Note, the Company shall
execute and deliver to the Holder a new Note (in accordance with Section 12(d)) representing the outstanding Principal.

 

(c)          Note
Exchangeable for Different Denominations. This Note is exchangeable, upon the surrender hereof by the Holder at the principal
office of the Company, for a new Note or Notes (in accordance with Section 12(d) and in principal amounts of at least $1,000) representing
in the aggregate the outstanding Principal of this Note, and each such new Note will represent such portion of such outstanding
Principal as is designated by the Holder at the time of such surrender.

 

(d)          Issuance
of New Notes. Whenever the Company is required to issue a new Note pursuant to the terms of this Note, such new Note (i) shall
be of like tenor with this Note, (ii) shall represent, as indicated on the face of such new Note, the Principal remaining outstanding
(or in the case of a new Note being issued pursuant to Section 12(a) or Section 12(c), the Principal designated by the Holder which,
when added to the principal represented by the other new Notes issued in connection with such issuance, does not exceed the Principal
remaining outstanding under this Note immediately prior to such issuance of new Notes), (iii) shall have an issuance date, as indicated
on the face of such new Note, which is the same as the Issuance Date of this Note, (iv) shall have the same rights and conditions
as this Note, and (v) shall represent accrued and unpaid Interest on the Principal of this Note, from the Issuance Date.

 

    	 	7	 

     

    

 

13.         REMEDIES,
CHARACTERIZATIONS, OTHER OBLIGATIONS, BREACHES AND INJUNCTIVE RELIEF. The remedies provided in this Note shall be cumulative
and in addition to all other remedies available under this Note and any of the other Transaction Documents at law or in equity
(including a decree of specific performance and/or other injunctive relief); provided, the Holder shall not be entitled to any
duplication or multiplication of damages. The Company covenants to the Holder that there shall be no characterization concerning
this instrument other than as expressly provided herein. Amounts set forth or provided for herein with respect to payments, conversion
and the like (and the computation thereof) shall be the amounts to be received by the Holder and shall not, except as expressly
provided herein or in the other Transaction Documents, be subject to any other obligation of the Company (or the performance thereof).
The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Holder and that the
remedy at law for any such breach may be inadequate. The Company therefore agrees that, in the event of any such breach or threatened
breach, the Holder shall be entitled, in addition to all other available remedies, to an injunction restraining any such breach
or any such threatened breach, without the necessity of showing economic loss and without any bond or other security being required.
The Company shall provide all information and documentation to the Holder that is reasonably requested by the Holder to enable
the Holder to confirm the Company’s compliance with the terms and conditions of this Note (including, without limitation,
compliance with Section 5). 

 

14.         PAYMENT
OF COLLECTION, ENFORCEMENT AND OTHER COSTS. If (a) this Note is placed in the hands of an attorney for collection or enforcement
of the debt evidenced hereby or is collected or enforced through any legal proceeding or the Holder otherwise takes action to collect
amounts due under this Note or to enforce the provisions of this Note or (b) there occurs any bankruptcy, reorganization, receivership
of the Company or other proceedings affecting Company creditors’ rights and involving a claim under this Note, then the Company
shall pay the reasonable costs incurred by the Holder for such collection, enforcement or action or in connection with such bankruptcy,
reorganization, receivership or other proceeding, including, without limitation, reasonable attorneys’ fees and disbursements.

 

15.         CONSTRUCTION;
HEADINGS. This Note shall be deemed to be jointly drafted by the Company and the Holder and shall not be construed against
any Person as the drafter hereof. The headings of this Note are for convenience of reference and shall not form part of, or affect
the interpretation of, this Note. 

 

16.         FAILURE
OR INDULGENCE NOT WAIVER. No failure or delay on the part of the Holder in the exercise of any power, right or privilege hereunder
shall operate as a waiver thereof, nor shall any single or partial exercise of any such power, right or privilege preclude other
or further exercise thereof or of any other right, power or privilege. No waiver shall be effective unless it is in writing and
signed by an authorized representative of the waiving party.

 

17.         DISPUTE
RESOLUTION. If the Holder and the Company are unable to agree as to the arithmetic calculation of the Conversion Price the
Holder and the Company will confer in good faith to resolve such disagreement and the Company shall promptly issue upon conversion
of this Note at the number of shares of Common Stock that are uncontested. Thereafter, the Company and Holder will confer in good
faith to attempt to reach agreement regarding the Conversion Price with the Required Holders; if the Required Holders and the Company
agree in writing upon a Conversion Price, that agreement will be binding on Holder and all holders of the Other Notes.

AMENDED AND RESTATED REGISTRATION
RIGHTS AGREEMENT 

 

THIS AMENDED AND
RESTATED REGISTRATION RIGHTS AGREEMENT (this “Agreement”) is made as of April 1, 2016 by and among Atomera
Incorporated, a Delaware corporation (the “Company”), and the persons listed on Schedule A hereto, referred
to individually as the “Holder” and collectively as the “Holders”.

 

A.           Pursuant
to that certain securities purchase agreement, dated March 17, 2015 (as amended, restated, supplemented, or otherwise modified
from time to time, including all schedules and exhibits thereto, collectively the “2015 Purchase Agreement”),
by and among the Company (f/k/a Mears Technologies, Inc.) and the investors listed on the Schedule of Buyers attached thereto (the
“Existing Noteholders”), the Company has sold, and each of the Existing Noteholders have purchased, severally
and not jointly, certain senior secured convertible notes in the aggregate original principal amount of up to $14,750,000 (the
“2015 Offering Notes”).

 

B.           In
respect of the 2015 Offering Notes, the Company, pursuant to this registration rights agreement, originally dated March 17, 2015
(the “2015 Registration Rights Agreement”), by and among the Company and the Existing Noteholders, provided
to the Existing Noteholders, and their assignees or successors in interest, certain rights to provide for the registration for
resale of their Conversion Shares by means of a Registration Statement under the Securities Act (as those terms are defined in
the 2015 Registration Rights Agreement).

 

C.           Pursuant
to that certain securities purchase agreement, dated even date herewith (as may be amended, restated, supplemented, or otherwise
modified from time to time, including all schedules and exhibits thereto, collectively, the “2016 Purchase Agreement”),
by and among the Company and the investors listed on the Schedule of Buyers attached thereto (the “New Noteholders”),
the Company has agreed to sell, and each of the New Noteholders have agreed to purchase, severally and not jointly, certain senior
secured convertible notes in the aggregate original principal amount of up to $6,000,000 (the “2016 Offering Notes”).

 

D.           To
induce the New Noteholders to purchase, severally and not jointly, the 2016 Offering Notes as provided for in the 2016 Purchase
Agreement, the Company has agreed to provide to the New Noteholders, and their assignees or successors in interest, certain rights
to provide for the registration for resale of their Conversion Shares by means of a Registration Statement under the Securities
Act (as those terms are defined below).

 

E.           The
Existing Noteholders have consented to allow the 2016 Offering Notes to be, in all respects, pari passu with the 2015 Offering
Notes in respect of this Agreement, and the Existing Noteholders now wish to amend and restate the 2015 Registration Rights Agreement
to allow each New Noteholder to become a party hereto. Accordingly, for purposes of this Agreement, the term “Holders”
shall mean both the Existing Noteholders and the New Noteholders.

 

F.           Unless
otherwise provided in this Agreement, capitalized terms used herein shall have the respective meanings set forth in Section 13
hereof.

 

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

 

     

     

    

 

1.          Registration.

 

(a)          Piggyback
Registrations Rights. If, at any time after the Company shall become subject to the periodic reporting obligations (a “Reporting
Company”) under the Securities Exchange Act through the date that is five years after the date the Company becomes a
Reporting Company, there is not an effective Registration Statement covering the Registrable Securities and the Company shall determine
to prepare and file with the Commission a Registration Statement relating to an offering for its own account or the account of
others under the Securities Act of any of its equity securities (other than on Form S-4 or Form S-8, each as promulgated under
the Securities Act, or their then equivalent relating to equity securities to be issued solely in connection with any acquisition
of any entity or business or equity securities issuable in connection with stock option or other employee benefit plans), then
the Company shall send to the Holders a written notice of such determination at least twenty (20) days prior to the filing of any
such Registration Statement and shall include in such Registration Statement all Registrable Securities requested by any Holder
hereunder to be included in the registration within ten (10) days after the Company sends such notice to the Holders (the “Piggyback
Shares”) for resale and offer on a continuous basis pursuant to Rule 415; provided, that (i) if, at any time after giving
written notice of its intention to register any securities and prior to the effective date of the Registration Statement filed
in connection with such registration, the Company determines for any reason not to proceed with or terminate such registration,
the Company will be relieved of its obligation to register any Registrable Securities in connection with such registration, (ii)
in case of a determination by the Company to delay registration of its securities, the Company will be permitted to delay the registration
of Registrable Securities for the same period as the delay in registering such other securities, (iii) each Holder is subject to
confidentiality obligations and shall not use or disclose any information gained in this process or any other material non-public
information he, she or it obtains, (iv) each Holder or assignee or successor in interest shall comply with all applicable laws
relating to insider trading or similar restrictions; and (v) if all of the Registrable Securities of the Holders cannot be so included
due to Commission Comments, Commission Guidance or Underwriter Cutbacks, then the Company may reduce, in accordance with the provisions
of Section 1(c) hereof, the number of Piggyback Shares included in such Registration Statement required to comply with such Commission
Comments, Commission Guidance or Underwriter Cutbacks.

 

(b)          Initial
Registration Statement. At the election of each Holder, the Company shall be required to include up to all Piggyback Shares
held by such Holder for resale and offer on a continuous basis pursuant to Rule 415 in the first Registration Statement filed after
the date that it becomes a Reporting Company (the “Initial Registration Statement”); provided, however,
that if all of the Piggyback Shares of the Holders cannot be so included due to Commission Comments, Commission Guidance or Underwriter
Cutbacks, then the Company may reduce, in accordance with the provisions of Section 1(c) hereof, the number of Piggyback Shares
included in such Registration Statement required to comply with such Commission Comments, Commission Guidance or Underwriter Cutbacks.

 

(c)          Cutback
Provisions. In the event all of the Registrable Securities cannot be or are not included in a Registration Statement due to
Commission Comments, Commission Guidance or Underwriter Cutbacks, the Company and the Holders agree that securities shall be removed
from such Registration Statement in the following order until no further removal is required by Commission Comments, Commission
Guidance or Underwriter Cutbacks:

 

(i)          First,
any securities held by any former employee, consultant or affiliate of the Company shall be removed, pro rata based on the number
of securities being registered for such former employees, consultants or affiliates held by all of the former employees of the
Company and any of their affiliates and successors in interest, whether pursuant to agreement or otherwise and any other person
with any registration rights outstanding on the date hereof;

 

    	 	2	 

     

    

 

(ii)         Second,
the securities held by National Securities Corporation (“National Securities”) and its members and affiliates,
if any, obtained solely by reason of providing services to the Company, which are being registered pursuant to any registration
rights agreement or otherwise (for clarity, any securities held by National Securities or its members or affiliates which were
acquired upon payment of a purchase price in cash or property will not be subject to this provision (c)(ii)); and

 

(iii)        Third,
the Registrable Securities held by the Holders that are requested to be included in the Registration Statement shall be removed,
pro rata based on the number of Registrable Shares held by each Holder in comparison to the number of Registrable Securities held
by all Holders who have requested to include any Registrable Securities in the Registration Statement.

 

(d)          Filing;
Content. The Company will use its commercially reasonable efforts to cause each Registration Statement pursuant to which any
Registrable Securities are included, including the Initial Registration Statement, to contain the Plan of Distribution substantially
similar to that attached hereto as Schedule B. The Company shall use its commercially reasonable efforts to cause any Registration
Statement filed under this Section 1, including the Initial Registration Statement, to be declared effective under the Securities
Act as promptly as practicable after the filing thereof and shall keep such Registration Statement continuously effective under
the Securities Act until the earlier of (i) one year after its Effective Date (provided, however, the one year period shall be
extended for any Grace Period), (ii) such time as all of the Registrable Securities covered by such Registration Statement have
been publicly sold by the Holders, or (iii) such time as all of the Registrable Securities covered by such Registration Statement
may be sold by the Holders pursuant to Rule 144 without regard to both the volume limitations for sales as provided in Rule 144
and the limitations for such sales provided in Rule 144(i), if applicable, as determined by the counsel to the Company pursuant
to a written opinion letter to such effect, addressed and acceptable to the Company's transfer agent and the affected Holder (“Effectiveness
Period”). By 5:00 p.m. (New York City time) on the business day immediately following the Effective Date of a Registration
Statement, the Company shall file with the Commission in accordance with Rule 424 under the Securities Act the final Prospectus
to be used in connection with sales pursuant to such Registration Statement (whether or not such filing is technically required
under such Rule). Notwithstanding the foregoing portion of this Section 1(e), the Company shall have the right in its sole discretion
to withdraw any Registration Statement filed under this Section 1 prior to its effectiveness.

 

(e)          Termination
of Piggyback Registration Rights. The registration rights afforded to each Holder under this Section 1 shall terminate on the
earliest date when all Registrable Securities of the Holder either: (i) have been publicly sold by the Holder pursuant to a Registration
Statement, (ii) have been covered by an effective Registration Statement which has been effective for an aggregate period of sixteen
(16) months (whether or not consecutive), provided, however, the time period shall be calculated so as to exclude any Grace Period,
or (iii) may be sold by the Holder pursuant to Rule 144 without regard to both the volume limitations for sales as provided in
Rule 144 and the limitations for such sales provided in Rule 144(i), if applicable, as determined by the counsel to the Company
pursuant to a written opinion letter to such effect, addressed and acceptable to the Company’s transfer agent and the affected
Holder in its reasonable discretion.

 

    	 	3	 

     

    

 

2.          Demand
Registration Rights.

 

(a)          Demand
Right. Commencing on the date that is one hundred eighty (180) days after the Company becomes a Reporting Company, the Holders
as a group representing at least 50% of the Registrable Securities (a “Requesting Group”) shall have a separate
one-time right, by written notice to the Company, signed by such Holders (the “Demand Notice”), to request the
Company to register for resale all Registrable Securities included by the Requesting Group in the Demand Notice (the “Demand
Shares”) under and in accordance with the provisions of the Securities Act by filing with the Commission a Registration
Statement covering the resale of such Demand Shares (the “Demand Registration Statement”). A copy of the Demand
Notice also shall be provided by the Company to each of the other Holders who will have fifteen (15) days to notify the Company
in writing to include their Registrable Securities as part of the Demand Shares, the failure of which, however, shall not in any
way affect the rights of the Requesting Group pursuant to this Section 2(a). The Demand Registration Statement required hereunder
shall be on any form of registration statement then available for the registration of the Registrable Securities, as selected by
the Company in accordance with applicable law and regulation. The Company will use its commercially reasonable efforts to file
the Demand Registration Statement within forty-five (45) days of the receipt of the Demand Notice, provided if the Demand Notice
is given within the forty-five (45) days after the prior fiscal year end, then the Company will use its reasonably commercial efforts
to file the Demand Registration Statement within ninety (90) days of the fiscal year end of the Company. The Company shall use
its commercially reasonable efforts to cause the Demand Registration Statement to be declared effective under the Securities Act
as promptly as practicable after the filing thereof and to keep the Demand Registration Statement continuously effective under
the Securities Act during the Effectiveness Period.

 

(b)          Inclusion
of Other Registrable Shares and Cutback Provisions. If as a result of Commission Comments or Commission Guidance, not all shares
are included that are desired to be included in a Registration Statement for the Demand Shares, the provisions of Section 1(c)
shall apply, subject to the Demand Priority (as defined below) of the Requesting Group. Pursuant to the piggyback registration
rights granted under this Agreement, the Company may include the Registrable Shares of the other Holders which will be subject
to the provision of Section 1(c) hereof, except that under Section 1(c)(iii), there will be no cutback of the Registrable Securities
of the Requesting Group until the Holders of Piggyback Shares and the shares of any other person exercising piggyback rights under
any other registration rights agreement (except for National Securities and their current and former affiliates, which shall have
the priority established in Section 1(c)) have been removed, and thereafter if any further Registrable Securities have to be removed
then those of the Requesting Group will be removed pro rata (the “Demand Priority”). Notwithstanding the foregoing,
if any other securities of any person other than the Holders or the Requesting Group or National Securities and their current and
former affiliates are included on the Demand Registration Statement, such securities will be removed, if required pursuant to Commission
Comments, after removal of the securities indicated in Section 1(c)(i) and before the securities indicated in Section 1(c)(ii),
as such persons decide among themselves, and if there is no agreement at to such removal provided to the Company within a reasonable
time, time being of the essence, then all the such securities will be removed.

 

(c)          Termination
of Demand Registration Rights. The registration rights afforded to each Holder under this Section 2 shall terminate on the
earliest date when all Registrable Securities of the Holder either: (i) have been publicly sold by the Holder pursuant to a Registration
Statement, (ii) have been covered by an effective Registration Statement which has been effective for an aggregate period of sixteen
(16) months (whether or not consecutive), provided, however, the time period shall be calculated so as to exclude
any Grace Period, or (iii) may be sold by the Holder pursuant to Rule 144 without regard to both the volume limitations for sales
as provided in Rule 144 and the limitations for such sales provided in Rule 144(i), if applicable, as determined by the counsel
to the Company pursuant to a written opinion letter to such effect, addressed and acceptable to the Company’s transfer agent
and the affected Holder in its reasonable discretion.

3.          Registration
Procedures. Whenever any Registrable Securities are to be registered pursuant to this Agreement, the Company shall use its
commercially reasonable efforts to effect the registration and sale of such Registrable Securities in accordance with the intended
method of disposition thereof, and pursuant thereto the Company shall have the following obligations:

 

(a)          The
Company shall prepare and file with the Commission a Registration Statement with respect to such Registrable Securities and use
its commercially reasonable efforts to cause such Registration Statement to become effective.

 

(b)          The
Company shall prepare and file with the Commission such amendments (including post-effective amendments) and supplements to a Registration
Statement and the Prospectus used in connection with such Registration Statement, which Prospectus is to be filed pursuant to Rule
424 promulgated under the Securities Act, as may be necessary to keep such Registration Statement effective at all times during
the Effectiveness Period, and, during such period, comply with the provisions of the Securities Act with respect to the disposition
of all Registrable Securities of the Company covered by such Registration Statement. In the case of amendments and supplements
to a Registration Statement which are required to be filed pursuant to this Agreement by reason of the Company filing a report
on Forms 10-K, 10-Q or Current Report on Form 8-K, or any analogous report under the Securities Exchange Act, the Company shall
have incorporated such report by reference into such Registration Statement, if applicable, or shall file such amendments or supplements
with the Commission on the same day on which the Securities Exchange Act report is filed which created the requirement for the
Company to amend or supplement such Registration Statement.

 

(c)          The
Company shall furnish to each Holder of Registrable Securities in any Registration Statement, without charge, (i) promptly after
the same is prepared and filed with the Commission at least one copy of such Registration Statement and any amendment(s) thereto,
including financial statements and schedules, all documents incorporated therein by reference, if requested by such seller, all
exhibits and each preliminary Prospectus, (ii) unless such Holder is exempt from the prospectus delivery requirements pursuant
to Rule 172 of the Securities Act, upon the effectiveness of any Registration Statement, ten (10) copies of the Prospectus included
in such Registration Statement and all amendments and supplements thereto (or such other number of copies as such seller may reasonably
request), and (iii) such other documents, including copies of any preliminary or final Prospectus, as such seller may reasonably
request from time to time in order to facilitate the disposition of the Registrable Securities owned by such seller.

 

(d)          The
Company shall use its commercially reasonable efforts to (i) register and qualify, unless an exemption from registration and qualification
applies, the resale by any seller of the Registrable Securities covered by a Registration Statement under such other securities
or “blue sky” laws of all applicable jurisdictions in the United States, (ii) prepare and file in those jurisdictions,
such amendments (including post-effective amendments) and supplements to such registrations and qualifications as may be necessary
to maintain the effectiveness thereof during the Effectiveness Period, (iii) take such other actions as may be necessary to maintain
such registrations and qualifications in effect at all times during the Effectiveness Period, and (iv) take all other actions reasonably
necessary or advisable to qualify the Registrable Securities for sale in such jurisdictions; provided, however, that
the Company shall not be required in connection therewith or as a condition thereto to (x) qualify to do business in any jurisdiction
where it would not otherwise be required to qualify but for this Section 3(d), (y) subject itself to general taxation in any such
jurisdiction, or (z) file a general consent to service of process in any such jurisdiction.

 

    	 	5	 

     

    

 

(e)          The
Company shall use its reasonable best efforts to prevent the issuance of any stop order or other suspension of effectiveness of
a Registration Statement, or the suspension of the qualification of any of Registrable Securities for sale in any jurisdiction
and, if such an order or suspension is issued, to obtain the withdrawal of such order or suspension at the earliest practicable
time and to notify the Holder of any Registrable Securities included in the offering under such Registration Statement of such
order and the resolution thereof or its receipt of actual notice of the initiation or threat of any proceeding for such purpose.

 

(f)          The
Company shall notify the Holder in writing of the happening of any event, as promptly as practicable after becoming aware of such
event, as a result of which the Prospectus included in a Registration Statement, as then in effect, includes an untrue statement
of a material fact or omission to state a material fact required to be stated therein or necessary to make the statements therein,
in the light of the circumstances under which they were made, not misleading (provided that in no event shall such notice contain
any material, nonpublic information), and, subject to Section 3(r), promptly prepare a supplement or amendment to such Registration
Statement to correct such untrue statement or omission, and, unless such Holder is exempt from the prospectus delivery requirements
pursuant to Rule 172 of the Securities Act, deliver ten (10) copies of such supplement or amendment to the Holder (or such other
number of copies as the Holder may reasonably request).

 

(g)          The
Company shall promptly notify the Holder in writing (i) when a Prospectus or any Prospectus supplement or post-effective amendment
has been filed, and when a Registration Statement or any post-effective amendment has become effective (notification of such effectiveness
shall be delivered to the Holder by email or facsimile on the same day of such effectiveness or by overnight delivery), (ii) of
any request by the Commission for amendments or supplements to a Registration Statement or related Prospectus or related information,
and (iii) of the Company’s reasonable determination that a post-effective amendment to a Registration Statement would be
appropriate.

 

(h)          If
the Holder is required under applicable Commission Guidance to be described in a Registration Statement as an underwriter, at the
reasonable request of such Holder, the Company shall use its best efforts to furnish to such Holder, on the date of the effectiveness
of such Registration Statement and thereafter from time to time on such dates as the Holder may reasonably request (i) a letter,
dated such date, from the Company’s independent certified public accountants in form and substance as is customarily given
by independent certified public accountants to underwriters in an underwritten public offering, addressed to the Holder, and (ii)
an opinion, dated as of such date, of counsel representing the Company for purposes of such Registration Statement, in form, scope
and substance as is customarily given in an underwritten public offering, addressed to the Holder.

 

(i)          If
the Holder is required under applicable Commission Guidance to be described in a Registration Statement as an underwriter, then
at the request of such Holder in connection with such Holder’s due diligence requirements, the Company shall make available
for inspection by (i) the Holder, (ii) the Holder’s legal counsel, and (iii) one firm of accountants or other agents retained
by the Holder (collectively, the “Inspectors”), all pertinent financial and other records, and pertinent corporate
documents and properties of the Company (collectively, the “Records”), as shall be reasonably deemed necessary
by each Inspector, and cause the Company’s officers, directors and employees to supply all information which any Inspector
may reasonably request; provided, however, that each Inspector shall agree to hold in strict confidence and shall
not make any disclosure (except to the Holder) or use of any Record or other information which the Company determines in good faith
to be confidential, and of which determination the Inspectors are so notified, unless (a) the release of such Records is ordered
pursuant to a final, non-appealable subpoena or order from a court or government body of competent jurisdiction, or (b) the information
in such Records has been made generally available to the public other than by disclosure in violation of this or any other agreement
of which the Inspector has knowledge. Each Holder agrees that it shall, upon learning that disclosure of such Records is sought
in or by a court or governmental body of competent jurisdiction or through other means, give prompt notice to the Company and allow
the Company, at its expense, to undertake appropriate action to prevent disclosure of, or to obtain a protective order for, the
Records deemed confidential. Nothing herein (or in any other confidentiality agreement between the Company and the Holder) shall
be deemed to limit the Holder’s ability to sell Registrable Securities in a manner which is otherwise consistent with applicable
laws and regulations. Notwithstanding the foregoing, each Holder acknowledges that the Records may contain material non-public
information and agrees that it shall strictly comply with the insider trading rules prohibiting the purchasing, selling or the
Company’s securities while in the possession of any such material non-public information.

 

    	 	6	 

     

    

 

 

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

 

(k)         The
Company shall (i) if applicable, use its best efforts to cause all of the Registrable Securities covered by a Registration Statement
to be listed on each securities exchange on which securities of the same class or series issued by the Company are then listed,
if any, if the listing of such Registrable Securities is then permitted under the rules of such exchange, or (ii) otherwise, use
its commercially reasonable efforts to secure designation and quotation of all of the Registrable Securities covered by a Registration
Statement on any one of the different levels of The NASDAQ Stock Market, or (iii) if, despite the Company’s best efforts
or commercially reasonable efforts, as applicable, to satisfy, the preceding clauses (i) and (ii) the Company is unsuccessful in
satisfying the preceding clauses (i) and (ii), to instead secure the inclusion for quotation on the Over-the-Counter Bulletin Board
for such Registrable Securities and, without limiting the generality of the foregoing, to use its commercially reasonable efforts
to encourage at least two market makers to register with the Financial Industry Regulatory Authority, Inc. (“FINRA”)
as such with respect to such Registrable Securities. For the avoidance of doubt, subject to and in accordance with Section 5, the
Company shall pay all fees and expenses of the Company in connection with satisfying its obligation under this Section 3(k).

 

(l)          If
requested by the Holder, and permissible under Commission Guidance, the Company shall (i) as soon as practicable incorporate in
a Prospectus supplement or post-effective amendment such information as the Holder reasonably requests to be included therein relating
to the sale and distribution of Registrable Securities, including, without limitation, information with respect to the Registrable
Securities being offered or sold, the purchase price being paid therefor and any other terms of the offering of the Registrable
Securities to be sold in such offering; (ii) as soon as practicable make all required filings of such Prospectus supplement or
post-effective amendment after being notified of the matters to be incorporated in such Prospectus supplement or post-effective
amendment; and (iii) as soon as practicable, supplement or make amendments to any Registration Statement if reasonably requested
by the Holder holding any Registrable Securities.

 

(m)        The
Company shall cooperate with each Holder who holds Registrable Securities being offered and, to the extent applicable, facilitate
the timely preparation and delivery of certificates (not bearing any restrictive legend) representing the Registrable Securities
to be offered pursuant to a Registration Statement and enable such certificates to be in such denominations or amounts, as the
case may be, as the Holder may reasonably request and registered in such names as the Holder may request.

 

    	 	7	 

     

    

 

(n)         The
Company shall use its commercially reasonable efforts to cause the Registrable Securities covered by a Registration Statement to
be registered with or approved by such other U.S. governmental agencies or authorities, but only in matters not contemplated Section
3(d) by or reasonably related to such matters (which matters are to be governed exclusively by Section 3(d)), as may be strictly
necessary to consummate the disposition of such Registrable Securities by the Holder strictly in accordance with the Plan of Distribution
included in the Registration Statement (as such Plan of Distribution may be modified from time to time in any filing with the Commission).

 

(o)         The
Company shall make generally available to its security holders as soon as practicable, but not later than ninety (90) days after
the close of the period covered thereby (or, if different, within the period permitted for the filing of reports on Forms 10-K
or 10-Q), an earnings statement (in form complying with, and in the manner provided by, the provisions of Rule 158 under the Securities
Act) covering a twelve-month period beginning not later than the first day of the Company’s fiscal quarter next following
the Effective Date of a Registration Statement.

 

(p)         The
Company shall otherwise use its commercially reasonable efforts to comply with all applicable rules and regulations of the Commission
in connection with any registration hereunder.

 

(q)         Within
two (2) business days after a Registration Statement which covers Registrable Securities is ordered effective by the Commission,
the Company shall deliver, and shall cause legal counsel for the Company to deliver, to the transfer agent for such Registrable
Securities (with copies to the Holder whose Registrable Securities are included in such Registration Statement) confirmation that
such Registration Statement has been declared effective by the Commission in the form attached hereto as Exhibit A and the
Irrevocable Transfer Agent Instructions in the form attached hereto as Exhibit B.

 

(r)          Notwithstanding
anything to the contrary herein, at any time after the Effective Date of a Registration Statement, the Company may delay the disclosure
of material, non-public information concerning the Company the disclosure of which at the time is not, in the good faith opinion
of the Board of Directors of the Company, in the best interest of the Company and not, after consultation with legal counsel, otherwise
required (a “Grace Period”); provided, that the Company shall promptly (i) notify the Holder in writing of the
existence of material, non-public information giving rise to a Grace Period (provided that in each notice the Company will not
disclose the content of such material, non-public information to the Holder) and the date on which the Grace Period will begin,
and (ii) notify the Holder in writing of the date on which the Grace Period ends; and, provided further, that no Grace Period shall
exceed sixty (60) consecutive days and during any three hundred sixty-five (365) day period such Grace Periods shall not exceed
an aggregate of one hundred twenty (120) days (each, an “Allowable Grace Period”). For purposes of determining
the length of a Grace Period above, the Grace Period shall begin on and include the date the Holder receives the notice referred
to in clause (i) and shall end on and include the later of the date the Holder receives the notice referred to in clause (ii) and
the date referred to in such notice. The provisions of Section 3(f) hereof shall not be applicable during the period of any Allowable
Grace Period. Upon expiration of the Grace Period, the Company shall again be bound by Section 3(f) with respect to the information
giving rise thereto unless such material, non-public information is no longer applicable. Notwithstanding anything to the contrary,
the Company shall cause its transfer agent to deliver unlegended shares of Common Stock to a transferee of the Holder in connection
with any sale of Registrable Securities with respect to which the Holder has entered into a contract for sale, and delivered a
copy of the Prospectus included as part of the applicable Registration Statement (unless an exemption from such Prospectus delivery
requirements exists), prior to the Holder’s receipt of the notice of a Grace Period or, if earlier, Holders knowledge of
the material, non-public information concerning the Company that gave rise to the Grace Period, and for which the Holder has not
yet settled.

4.           Obligations
of the Holders.

 

(a)          At
least five (5) business days prior to the first anticipated filing date of a Registration Statement, the Company shall notify the
Holders in writing of the information the Company requires from each Holder if the Holder’s Registrable Securities are to
be included in such Registration Statement. It shall be a condition precedent to the obligations of the Company to complete the
registration pursuant to this Agreement with respect to any Registrable Securities of the Holder that the Holder shall furnish
to the Company such information regarding itself, the Registrable Securities held by it and the intended method of disposition
of the Registrable Securities held by it as shall be reasonably required to effect the effectiveness of the registration of such
Registrable Securities and shall execute such documents in connection with such registration as the Company may reasonably request.

 

(b)          The
Holder, by the Holder’s acceptance of the Registrable Securities, agrees to cooperate with the Company as reasonably requested
by the Company in connection with the preparation and filing of any Registration Statement hereunder, unless the Holder has notified
the Company in writing of the Holder's election to exclude all of the Holder’s Registrable Securities from such Registration
Statement.

 

(c)          The
Holder agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in Sections
3(e) or 3(f) or of a Grace Period under Section 3(r), the Holder will immediately discontinue disposition of Registrable Securities
pursuant to any Registration Statement(s) covering such Registrable Securities until the Holder’s receipt of the copies of
the supplemented or amended Prospectus contemplated by Sections 3(e) or 3(f) or receipt of notice that no supplement or amendment
is required. Notwithstanding anything to the contrary, the Company shall cause its transfer agent to deliver unlegended shares
of Common Stock to a transferee of the Holder in connection with any sale of Registrable Securities with respect to which the Holder
has entered into a contract for sale prior to the Holder’s receipt of a notice from the Company of the happening of any event
of the kind described in Sections 3(e) or 3(f) or of any Grace Period, or, if earlier, Holders knowledge of the material, non-public
information concerning the Company or the facts or circumstances that gave rise to the Grace Period or of the Section 3(e) or 3(f)
event, and for which the Holder has not yet settled.

 

(d)          The
Holder covenants and agrees that it will comply with the Prospectus delivery requirements of the Securities Act as applicable to
it or an exemption therefrom in connection with sales of Registrable Securities pursuant to a Registration Statement.

 

5.           Registration
Expenses. All expenses incident to the Company’s performance of or compliance with this Agreement, including without
limitation all registration and filing fees, fees and expenses of compliance with securities or blue sky laws, printing expenses,
messenger and delivery expenses, fees and disbursements of custodians, and fees and disbursements of counsel for the Company and
all independent certified public accountants, underwriters retained by the Company (excluding discounts, commissions and placement
agent fees) and other Persons retained by the Company (all such expenses being herein called “Registration Expenses”),
shall be borne by the Company. Further, the Company shall pay its internal expenses (including, without limitation, all salaries
and expenses of its officers and employees performing legal or accounting duties), the expense of any annual audit or quarterly
review, the expense of any liability insurance and the expenses and fees for listing the securities to be registered on each securities
exchange on which similar securities issued by the Company are then listed.

6.           Indemnification.

 

In the event any Registrable
Securities are included in a Registration Statement under this Agreement:

 

(a)          To
the fullest extent permitted by law, the Company will, and hereby does, indemnify, hold harmless and defend the Holder, the directors,
officers, members, partners, employees, agents, representatives of, and each Person, if any, who controls the Holder within the
meaning of the Securities Act or the Securities Exchange Act (each, an “Indemnified Person”), against any losses,
claims, damages, liabilities, judgments, fines, penalties, charges, costs, reasonable attorneys’ fees, amounts paid in settlement
or expenses, joint or several, (collectively, “Claims”) incurred in investigating, preparing or defending any
action, claim, suit, inquiry, proceeding, investigation or appeal taken from the foregoing by or before any court or governmental,
administrative or other regulatory agency, body or the Commission, whether pending or threatened, whether or not an indemnified
party is or may be a party thereto (“Indemnified Damages”), to which any of them may become subject insofar
as such Claims (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon:
(i) any untrue statement or alleged untrue statement of a material fact in a Registration Statement or any post-effective amendment
thereto or in any filing made in connection with the qualification of the offering under the securities or other “blue sky”
laws of any jurisdiction in which Registrable Securities are offered, or the omission or alleged omission to state a material fact
required to be stated therein or necessary to make the statements therein not misleading, (ii) any untrue statement or alleged
untrue statement of a material fact contained in any preliminary Prospectus if used prior to the effective date of such Registration
Statement, or contained in the final Prospectus (as amended or supplemented, if the Company files any amendment thereof or supplement
thereto with the Commission) or the omission or alleged omission to state therein any material fact necessary to make the statements
made therein, in the light of the circumstances under which the statements therein were made, not misleading, (iii) any violation
or alleged violation by the Company of the Securities Act or the Securities Exchange Act, any other law, including, without limitation,
any state securities law, or any rule or regulation thereunder relating to the offer or sale of the Registrable Securities pursuant
to a Registration Statement or (iv) any violation of this Agreement (the matters in the foregoing clauses (i) through (iv) being,
collectively, “Violations”). Subject to Section 6(c), the Company shall reimburse the Indemnified Persons, promptly
as such expenses are incurred and are due and payable, for any legal fees or other reasonable expenses incurred by them in connection
with investigating or defending any such Claim. Notwithstanding anything to the contrary contained herein, the indemnification
agreement contained in this Section 6(a): (i) shall not apply to a Claim by an Indemnified Person arising out of or based upon
a Violation which occurs based on a Holder’s material breach of its covenants or agreements in Section 4(c) or (d) or in
reliance upon and in conformity with information furnished in writing to the Company by such Indemnified Person or by a Related
Information Provider expressly for use in connection with the preparation of the Registration Statement or any such amendment thereof
or supplement thereto and (ii) shall not be available to the extent such Claim is based on a failure of the Holder to deliver or
to cause to be delivered the Prospectus made available by the Company, including a corrected Prospectus, if such Prospectus or
corrected Prospectus was timely made available by the Company pursuant to Section 3(c); and (iii) shall not apply to amounts paid
in settlement of any Claim if such settlement is effected without the prior written consent of the Company, which consent shall
not be unreasonably withheld or delayed. Such indemnity shall remain in full force and effect regardless of any investigation made
by or on behalf of the Indemnified Person and shall survive the transfer of the Registrable Securities by the Holder pursuant to
Section 10. “Related Information Provider” means, in respect of any Indemnified Person, the Holder to which
such Indemnified Person is related or another Indemnified Person that is related to the Holder to which such Indemnified Person
is related.

 

    	 	10	 

     

    

 

(b)          To
the fullest extent permitted by law, in connection with any Registration Statement in which a Holder’s Registrable Securities
are included or in which a Holder is otherwise participating, such Holder will severally and not jointly indemnify and hold harmless
the Company, each of its directors, each of its officers who has signed the Registration Statement, each Person, if any, who controls
the Company within the meaning of the Securities Act, any underwriter, any other Holder or other Person selling securities in such
Registration Statement and any controlling person of any such underwriter or other Holder or other Person (each an “Other
Indemnified Person”), against any Claims or Indemnified Damages to which any of them may become subject, under the Securities
Act, the Exchange Act or otherwise, insofar as such Claim or Indemnified Damages arise out of or are based upon any Violation,
in each case to the extent, and only to the extent, that such Violation occurs based on a Holder’s material breach of its
covenants or agreements in Section 4(c) or (d) or in reliance upon and in conformity with written information furnished by such
Holder or by a Related Information Provider expressly for use in connection with such Registration Statement; and each such Holder
will pay, as incurred, any legal or other expenses reasonably incurred by any Other Indemnified Person intended to be indemnified
pursuant to this Section 6(b), in connection with investigating or defending any such Claim; provided, however, that
the indemnity agreement contained in this Section 6(b) shall not apply to amounts paid in settlement of any such Claim if such
settlement is effected without the prior written consent of the Holder, which consent shall not be unreasonably withheld; provided,
further, however, that the Holder shall be liable under this Section 6(b) for only that amount of a Claim or Indemnified
Damages as does not exceed the net proceeds to the Holder as a result of the sale of Registrable Securities pursuant to such Registration
Statement, except in the case of fraud by such Holder. Such indemnity shall remain in full force and effect regardless of any investigation
made by or on behalf of such Other Indemnified Person and shall survive the transfer of the Registrable Securities by the Holder
pursuant to Section 10.

 

(c)          Promptly
after receipt by an Indemnified Person or Other Indemnified Person under this Section 6 of notice of the commencement of any action
or proceeding (including any governmental action or proceeding) involving a Claim, such Indemnified Person or Other Indemnified
Person shall, if a claim for indemnification in respect thereof is to be made against any indemnifying party under this Section
6, deliver to the indemnifying party a written notice of the commencement thereof, and the indemnifying party shall have the right
to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed,
to assume control of the defense thereof with counsel mutually satisfactory to the indemnifying party and reasonably satisfactory
to the Indemnified Person or the Other Indemnified Person, as the case may be; provided, however, that an Indemnified
Person or Other Indemnified Person shall have the right to retain its own counsel with the fees and expenses of not more than one
counsel for all such Indemnified Persons or all such Other Indemnified Persons to be paid by the indemnifying party, if, in the
reasonable opinion of counsel retained by the indemnifying party, the representation by such counsel of the Indemnified Person
or Other Indemnified Person and the indemnifying party would be inappropriate due to actual or potential differing interests between
such Indemnified Person or Other Indemnified Person and any other party represented by such counsel in such proceeding. The Other
Indemnified Person or Indemnified Person, as applicable, shall cooperate fully with the indemnifying party in connection with any
negotiation or defense of any such action or Claim by the indemnifying party and shall furnish to the indemnifying party all information
reasonably available to such Other Indemnified Person or such Indemnified Person which relates to such action or Claim. The indemnifying
party shall keep the Other Indemnified Person or Indemnified Person, as applicable, reasonably apprised at all times as to the
status of the defense or any settlement negotiations with respect thereto. No indemnifying party shall be liable for any settlement
of any action, claim or proceeding effected without its prior written consent; provided, however, that the indemnifying
party shall not unreasonably withhold, delay or condition its consent. No indemnifying party shall, without the prior written consent
of the Other Indemnified Person or Indemnified Person, as applicable, consent to entry of any judgment or enter into any settlement
or other compromise which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Other
Indemnified Person or such Indemnified Person of a release from all liability in respect to the Claim at issue, and such settlement
shall not include any admission as to fault on the part of such Other Indemnified Person or such Indemnified Person. Following
indemnification as provided for hereunder, the indemnifying party shall be subrogated to all rights of the Other Indemnified Person
or Indemnified Person, as applicable, with respect to all third parties, firms or corporations relating to the matter for which
indemnification has been made. The failure to deliver written notice to the indemnifying party within a reasonable time of the
commencement of any such action shall not relieve such indemnifying party of any liability to the Indemnified Person or Other Indemnified
Person, as applicable, under this Section 6, except to the extent that the indemnifying party is materially prejudiced in its ability
to defend such action.

 

    	 	11	 

     

    

 

(d)          The
indemnification required by this Section 6 shall be made by periodic payments of the amount thereof during the course of the investigation
or defense, as and when bills are received or Indemnified Damages are incurred, subject to an undertaking by the Indemnified Person
or the Other Indemnified Person, as applicable, to return such payments to the extent a court of competent jurisdiction or other
competent authority determines that such payments were unlawful or were not required under this Agreement.

 

(e)          Without
any duplication or multiplication of damages, the indemnity agreements contained herein shall be in addition to (i) any cause of
action or similar right of the Other Indemnified Person or Indemnified Person against the indemnifying party or others, and (ii)
any liabilities the indemnifying party may be subject to pursuant to the law.

 

(f)          Unless
suspended by the underwriting agreement applicable to any registration, the obligations of the Company and Holders under this Section
6 shall survive the completion of any offering of Registrable Securities in a Registration Statement under this Agreement, or otherwise.

 

7.           Contribution.
To the extent any indemnification by an indemnifying party is prohibited or limited by law, such indemnifying party agrees to make

Ladies and Gentlemen:

 

[We are][I am] counsel
to Atomera Incorporated, a Delaware corporation (the “Company”), and have represented the Company in connection with

Company filed a registration statement on Form S-[1] (File No. 333-_____________) (the “Registration Statement”) with
the Securities and Exchange Commission (the “SEC”) relating to the Registrable Securities which names the Holder as
a selling stockholder thereunder.

 

In connection with the
foregoing, [we][I] advise you that a member of the SEC’s staff has advised [us][me] by telephone that the SEC has entered
an order declaring the Registration Statement effective under the 1933 Act at [ENTER TIME OF EFFECTIVENESS] on [ENTER DATE OF EFFECTIVENESS]
and [we][I] have no knowledge, after telephonic inquiry of a member of the SEC’s staff, that any stop order suspending its
effectiveness has been issued or that any proceedings for that purpose are pending before, or threatened by, the SEC and the Registrable
Securities are available for resale under the 1933 Act pursuant to the Registration Statement.

 

If applicable, you may
receive notices from the Company pursuant to the Company’s rights or obligations under the Registration Rights Agreement
in connection with stop orders or other restrictions on transfer of the shares included in such Registration Statement, but [we][I]
[are][am] not obligated to update this letter or otherwise inform you of any such stop order or restriction.

Attention:[________________________]

 

Ladies and Gentlemen:

 

Reference is made to
that certain Amended and Restated Registration Rights Agreement, dated as of April 1, 20116 (the “Agreement”),
by and among Atomera Incorporated, a Delaware corporation (the “Company”), _________________________ (the “Holder”)
and certain other securityholders of the Company, pursuant to which the Company is obligated to register certain shares held by
the Holder (the “Holder Shares”) of Common Stock of the Company, par value $0.001 per share (the “Common
Stock”).

 

This letter shall serve
as our irrevocable authorization and direction to you (provided that you are the transfer agent of the Company at such time) to
issue shares of Common Stock upon transfer or resale of the Holder Shares, unless we have otherwise informed you of the termination
of effectiveness of the registration statement in which the Holder Shares are included, a stop order or another transfer restriction.
We may also later inform you that after the termination of effectiveness of such registration statement that a registration statement
in which the Holder’s Shares are included, or that such stop order has been lifted or that such transfer restriction is not
applicable, in which case this authorization and direction shall be reinstated and be effective.

 

You acknowledge and agree
that so long as you have previously received (a) written confirmation from the Company's legal counsel that either (i) a registration
statement covering resales of the Holder Shares has been declared and remains effective by the Securities and Exchange Commission
(the “SEC”) under the Securities Act of 1933, as amended (the “1933 Act”), or (ii) sales
of the Holder Shares may be made in conformity with Rule 144 under the 1933 Act (“Rule 144”), (b) if applicable,
a copy of such registration statement, and (c) notice from legal counsel to the Company or any Holder that a transfer of Holder
Shares has been effected either pursuant to the registration statement (and a prospectus delivered to the transferee) or pursuant
to Rule 144, then as promptly as practicable, you shall issue the certificates representing the Holder Shares registered
in the names of such transferees, and such certificates shall not bear any legend restricting transfer of the Common Stock evidenced
thereby and should not be subject to any stop-transfer restriction; provided, however, that if such shares of Common Stock and
are not registered for resale under the 1933 Act or able to be sold under Rule 144, then the certificates for such Common Shares
shall bear the following legend:

 

    	 	B-1	 

     

    

 

THE SECURITIES REPRESENTED BY
THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS. THE
SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED (I) IN THE ABSENCE OF (A) AN EFFECTIVE REGISTRATION STATEMENT

THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT OR (II) UNLESS SOLD PURSUANT TO RULE 144 OR RULE 144A UNDER SAID ACT. NOTWITHSTANDING
THE FOREGOING, THE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN OR FINANCING ARRANGEMENT
SECURED BY THE SECURITIES.

 

A form of written confirmation
from the Company’s outside legal counsel that a registration statement covering resales of the Holder Shares has been declared
effective by the SEC under the 1933 Act is attached hereto. We will inform you of any stop orders or other transfer restrictions.

SELLING STOCKHOLDERS

 

The shares of common
stock being offered by the selling stockholders are those issuable to the selling stockholders upon [conversion of the notes and
exercise of the warrants]. For additional information regarding the issuance of the [notes and the warrants], see “Private
Placement of Notes” above. We are registering the shares of common stock in order to permit the selling stockholders to offer
the shares for resale [from time to time]. Except for the ownership of [the notes issued pursuant to and in connection with the
Securities Purchase Agreement, and the warrants issued pursuant to and the agreements governing our engagement of National Securities
Corporation as a placement agent for the private placement of the notes and the engagement of National Securities Corporation as
an underwriter for a public offering of common stock by the Company] the selling stockholders have not had any material relationship
with us within the past three years.

 

The table below lists
the selling stockholders and other information regarding the beneficial ownership (as determined under Section 13(d) of the Securities
Exchange Act of 1934, as amended, and the rules and regulations thereunder) of the shares of common stock held by each of the selling
stockholders. The second column lists the number of shares of common stock beneficially owned by the selling stockholders, based
on their respective ownership of shares of common stock [, notes and warrants,] as of ________, 20__, [assuming conversion of the
notes and exercise of the warrants held by each such selling stockholder on that date but taking account of any limitations on
conversion and exercise set forth therein].

 

The third column lists
the shares of common stock being offered by this prospectus by the selling stockholders [and does not take into account any limitations
on (i) conversion of the notes set forth therein or (ii) exercise of the warrants set forth therein].

 

In accordance with
the terms of a registration rights agreement with the holders of the notes and the warrants, this prospectus generally covers the
resale of [(i) the shares of common stock issued upon conversion of the notes and (ii) the maximum number of shares of common stock
issuable upon exercise of the warrants, in each case, determined as if the outstanding notes and warrants were converted or exercised
(as the case may be) in full (without regard to any limitations on conversion or exercise contained therein) as of the trading
day immediately preceding the date this registration statement was initially filed with the SEC]. Because the conversion price
of the notes and the exercise price of the warrants may be adjusted, the number of shares that will actually be issued may be more
or less than the number of shares being offered by this prospectus. The fourth column assumes the sale of all of the shares offered
by the selling stockholders pursuant to this prospectus.

Distribution.”

fees and expenses incident to our obligation to register the shares of common stock.

may sell all or a portion of the shares of common stock held by them and offered hereby [from time to time] [directly or] through
one or more underwriters, broker-dealers or agents. If the shares of common stock are sold through underwriters or broker-dealers,
the selling stockholders will be responsible for underwriting discounts or commissions or agent’s commissions. The shares
of common stock may be sold in one or more transactions at fixed prices, at prevailing market prices at the time of the sale, at
varying prices determined at the time of sale or at negotiated prices. These sales may be effected in transactions, which may involve
crosses or block transactions, pursuant to one or more of the following methods:

 

		·	on any national securities exchange or quotation service on which the securities may be listed
or quoted at the time of sale;

		·	in the over-the-counter market;

		·	in transactions otherwise than on these exchanges or systems or in the over-the-counter market;

		·	through the writing or settlement of options, whether such options are listed on an options exchange
or otherwise;

		·	ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

		·	block trades in which the broker-dealer will attempt to sell the shares as agent but may position
and resell a portion of the block as principal to facilitate the transaction;

		·	purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

		·	an exchange distribution in accordance with the rules of the applicable exchange;

		·	privately negotiated transactions;

		·	short sales made after the date the Registration Statement is declared effective by the SEC;

		·	broker-dealers may agree with a selling security holder to sell a specified number of such shares
at a stipulated price per share;

		·	a combination of any such methods of sale; and

		·	any other method permitted pursuant to applicable law.

 

The selling stockholders
may also sell shares of common stock under Rule 144 promulgated under the Securities Act of 1933, as amended, if available, rather
than under this prospectus. In addition, the selling stockholders may transfer the shares of common stock by other means not described
in this prospectus. If the selling stockholders effect such transactions by selling shares of common stock to or through underwriters,
broker-dealers or agents, such underwriters, broker-dealers or agents may receive commissions in the form of discounts, concessions
or commissions from the selling stockholders or commissions from purchasers of the shares of common stock for whom they may act
as agent or to whom they may sell as principal (which discounts, concessions or commissions as to particular underwriters, broker-dealers
or agents may be in excess of those customary in the types of transactions involved). In connection with sales of the shares of
common stock or otherwise, the selling stockholders may enter into hedging transactions with broker-dealers, which may in turn
engage in short sales of the shares of common stock in the course of hedging in positions they assume. The selling stockholders
may also sell shares of common stock short and deliver shares of common stock covered by this prospectus to close out short positions
and to return borrowed shares in connection with such short sales. The selling stockholders may also loan or pledge shares of common
stock to broker-dealers that in turn may sell such shares.

 

     

     

    

 

The selling stockholders
may pledge or grant a security interest in some or all of the [notes, warrants or] shares of common stock owned by them and, if
they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of
common stock from time to time pursuant to this prospectus or any amendment to this prospectus under Rule 424(b)(3) or other applicable
provision of the Securities Act amending, if necessary, the list of selling stockholders to include the pledgee, transferee or
other successors in interest as selling stockholders under this prospectus. The selling stockholders also may transfer and donate
the shares of common stock in other circumstances in which case the transferees, donees, pledgees or other successors in interest
will be the selling beneficial owners for purposes of this prospectus.

 

To the extent required
by the Securities Act and the rules and regulations thereunder, the selling stockholders and any broker-dealer participating in
the distribution of the shares of common stock may be deemed to be “underwriters” within the meaning of the Securities
Act, and any commission paid, or any discounts or concessions allowed to, any such broker-dealer may be deemed to be underwriting
commissions or discounts under the Securities Act. At the time a particular offering of the shares of common stock is made, a prospectus
supplement, if required, will be distributed, which will set forth the aggregate amount of shares of common stock being offered
and the terms of the offering, including the name or names of any broker-dealers or agents, any discounts, commissions and other
terms constituting compensation from the selling stockholders and any discounts, commissions or concessions allowed or re-allowed
or paid to broker-dealers.

 

Under the securities
laws of some states, the shares of common stock may be sold in such states only through registered or licensed brokers or dealers.
In addition, in some states the shares of common stock may not be sold unless such shares have been registered or qualified for
sale in such state or an exemption from registration or qualification is available and is complied with.

 

There can be no assurance
that any selling stockholder will sell any or all of the shares of common stock registered pursuant to the registration statement,
of which this prospectus forms a part.

 

The selling stockholders
and any other person participating in such distribution will be subject to applicable provisions of the Securities Act of 1933,
as amended, and the Securities Exchange Act of 1934, as amended, and in each case together with the rules and regulations thereunder,
including, without limitation, to the extent applicable, Regulation M of the Exchange Act, which may limit the timing of purchases
and sales of any of the shares of common stock by the selling stockholders and any other participating person. To the extent applicable,
Regulation M may also restrict the ability of any person engaged in the distribution of the shares of common stock to engage in
market-making activities with respect to the shares of common stock. All of the foregoing may affect the marketability of the shares
of common stock and the ability of any Person to engage in market-making activities with respect to the shares of common stock.

 

We will pay all expenses
of the registration of the shares of common stock pursuant to the registration rights agreement, estimated to be $[     ]
in total, including, without limitation, Securities and Exchange Commission filing fees and expenses of compliance with state securities
or “blue sky” laws; provided, however, a selling stockholder will pay all underwriting discounts and selling commissions,
if any. We will indemnify the selling stockholders against liabilities, including some liabilities under the Securities Act in
accordance with the registration rights agreements or the selling stockholders will be entitled to contribution. We may be indemnified
by the selling stockholders against civil liabilities, including liabilities under the Securities Act that may arise from any written
information furnished to us by the selling stockholder specifically for use in this prospectus, in accordance with the related
registration rights agreements or we may be entitled to contribution.

     

     

    

 

Once sold under the
registration statement, of which this prospectus forms a part, the shares of common stock will be freely tradable in the hands
of persons other than our affiliates.

3.            Acceptance
by Escrow Agent. The Escrow Agent hereby accepts and agrees to perform its obligations hereunder, provided that:

 

    	 	2	 

     

    

 

(a)          The
Escrow Agent may act in reliance upon any signature believed by it to be genuine, and may assume that any person who has been designated
by Placement Agent or the Company to give any written instructions, notice or receipt, or make any statements in connection with
the provisions hereof has been duly authorized to do so. Escrow Agent shall have no duty to make inquiry as to the genuineness,
accuracy or validity of any statements or instructions or any signatures on statements or instructions. The names and true signatures
of each individual authorized to act singly on behalf of the Company and Placement Agent are stated in Schedule II, which
is attached hereto and made a part hereof. The Company and Placement Agent may each remove or add one or more of its authorized
signers stated on Schedule II by notifying the Escrow Agent of such change in accordance with this Agreement, which notice
shall include the true signature for any new authorized signatories.

 

(b)          The
Escrow Agent may act relative hereto in reliance upon advice of counsel in reference to any matter connected herewith. The Escrow
Agent shall not be liable for any mistake of fact or error of judgment or law, or for any acts or omissions of any kind, unless
caused by its willful misconduct or gross negligence.

 

(c)          The
Placement Agent and the Company agree to indemnify and bold the Escrow Agent harmless from and against any and all claims, losses,
costs, liabilities, damages, suits, demands, judgments or expenses (including but not limited to reasonable attorney’s fees)
claimed against or incurred by Escrow Agent arising out of or related, directly or indirectly, to this Escrow Agreement unless
caused by the Escrow Agent’s gross negligence or willful misconduct.

 

(d)          In
the event that the Escrow Agent shall be uncertain as to its duties or rights hereunder, the Escrow Agent shall be entitled to
(i) refrain from taking any action other than to keep safely the Escrow Funds until it shall be directed otherwise by a court of
competent jurisdiction, or (ii) deliver the Escrow Funds to a court of competent jurisdiction.

 

(e) The Escrow Agent
shall have no duty, responsibility or obligation to interpret or enforce the terms of any agreement other than Escrow Agent’s
obligations hereunder, and the Escrow Agent shall not be required to make a request that any monies be delivered to the Escrow
Account, it being agreed that the sole duties and responsibilities of the Escrow Agent shall be to the extent not prohibited by
applicable law (i) to accept checks or other instruments for the payment of money and wire transfers delivered to the Escrow Agent
for the Escrow Account and deposit said checks and wire transfers into the non-interest bearing Escrow Account, and (ii) to disburse
or refrain from disbursing the Escrow Funds as stated above, provided that the checks received by the Escrow Agent have been collected
and are available for withdrawal.

 

4.            Escrow
Account Statements and Information. The Escrow Agent agrees to send to the Company and/or the Placement Agent a copy of the
Escrow Account periodic statement, upon request in accordance with the Escrow Agent’s regular practices for providing account
statements to its non-escrow clients and to also provide the Company and/or Placement Agent, or their designee, upon request other
deposit account information, including Escrow Account balances, by telephone or by computer communication, to the extent practicable.
The Company and Placement Agent agree to complete and sign all forms or agreements required by the Escrow Agent for that purpose.
The Company and Placement Agent each consent to the Escrow Agent’s release of such Escrow Account information to any of the
individuals designated by Company or Placement Agent, which designation has been signed in accordance with section 3(a) by any
of the persons in Schedule II. Further, the Company and Placement Agent have an option to receive e-mail notification of incoming
and outgoing wire transfers. If this e-mail notification service is requested and subsequently approved by the Escrow Agent, the
Company and/or Placement Agent agrees to provide a valid e-mail address and other information necessary to set-up this service
and sign all forms and agreements required for such service. The Company and Placement Agent each consent to the Escrow Agent’s
release of wire transfer information to the designated e-mail address(es). The Escrow Agent’s liability for failure to comply
with this section shall not exceed the cost of providing such information.

 

    	 	3	 

     

    

 

5.            Resignation
and Termination of the Escrow Agent. The Escrow Agent may resign at any time by giving thirty (30) days’ prior written
notice of such resignation to Placement Agent and the Company. Upon providing such notice, the Escrow Agent shall have no further
obligation hereunder except to hold as depositary the Escrow Funds that it receives until the end of such thirty (30)-day period.
In such event, the Escrow Agent shall not take any action, other than receiving and depositing Subscribers checks and wire transfers
in accordance with this Agreement, until the Company has designated a banking corporation, trust company, attorney or other person
as successor. Upon receipt of such written designation signed by Placement Agent and the Company, the Escrow Agent shall promptly
deliver the Escrow Funds to such successor and shall thereafter have no further obligations hereunder. If such instructions are
not received within 30 days following the effective date of such resignation, then the Escrow Agent may deposit the Escrow Funds
held by it pursuant to this Agreement with a clerk of a court of competent jurisdiction pending the appointment of a successor.
In either case provided for in this section, the Escrow Agent shall be relieved of all further obligations and released from all
liability thereafter arising with respect to the Escrow Funds.

 

6.            Termination.
The Company and Placement Agent may terminate the appointment of the Escrow Agent hereunder upon written notice specifying the
date upon which such termination shall take effect, which date shall be at least 30 days from the date of such notice. In the event
of such termination, the Company and Placement Agent shall, within 30 days of such notice, appoint a successor escrow agent and
the Escrow Agent shall, upon receipt of written instructions signed by the Company and Placement Agent, turn over to such successor
escrow agent all of the Escrow Funds; provided, however, that if the Company and Placement Agent fail to appoint a successor
escrow agent within such 30-day period, such termination notice shall be null and void and the Escrow Agent shall continue to be
bound by all of the provisions hereof. Upon receipt of the Escrow Funds, the successor escrow agent shall become the escrow agent
hereunder and shall be bound by all of the provisions hereof and Escrow Agent shall be relieved of all further obligations and
released from all liability thereafter arising with respect to the Escrow Funds and under this Agreement.

 

7.            Investment.
All funds received by the Escrow Agent shall be held only in non-interest bearing bank accounts at Escrow Agent.

 

8.            Compensation.
The Escrow Agent shall be entitled, for the duties to be performed by it hereunder, to a fee of $4,000.00, which fee shall be paid
by the Company upon the signing of this Agreement. In addition, the Company shall be obligated to reimburse Escrow Agent for all
fees, costs and expenses incurred or that become due in connection with this Agreement or the Escrow Account, including reasonable
attorney’s fees. Neither the modification, cancellation, termination or rescission of this Agreement nor the resignation
or termination of the Escrow Agent shall affect the right of Escrow Agent to retain the amount of any fee which has been paid,
or to be reimbursed or paid any amount which has been incurred or becomes due, prior to the effective date of any such modification,
cancellation, termination, resignation or rescission. To the extent the Escrow Agent has incurred any such expenses, or any such
fee becomes due, prior to any closing, the Escrow Agent shall advise the Company and the Company shall direct all such amounts
to be paid directly at any such closing.

 

9.            Notices.
All notices, requests, demands and other communications required or permitted to be given hereunder shall be in writing and shall

AMENDED AND RESTATED SECURITY AGREEMENT

 

This AMENDED AND RESTATED
SECURITY AGREEMENT (this “Agreement”), dated as of April 1, 2016, is made by and among Atomera Incorporated,
a Delaware corporation (the “Grantor”), Robert Clifford, as the Collateral Agent, and the secured parties listed
on Schedule A annexed hereto (collectively, the “Secured Parties” and each, individually, a “Secured
Party”).

 

RECITALS

 

WHEREAS, pursuant
to that certain securities purchase agreement, dated March 17, 2015 (as amended, restated, supplemented, or otherwise modified
from time to time, including all schedules and exhibits thereto, collectively the “2015 Purchase Agreement”),
by and among the Grantor (f/k/a Mears Technologies, Inc.) and the investors listed on the Schedule of Buyers attached thereto (the
“Existing Noteholders”), the Grantor has sold, and each of the Existing Noteholders have purchased, severally
and not jointly, certain senior secured convertible notes in the aggregate original principal amount of up to $14,750,000 (the
“2015 Offering Notes”); and

 

WHEREAS, in respect
of the 2015 Offering Notes, the Grantor has, pursuant to this security agreement, originally dated March 17, 2015 (the “2015
Security Agreement”), by and among Grantor and the Existing Noteholders, granted a continuing security interest in and
to the Collateral (as defined in the 2015 Security Agreement) in order to secure the prompt and complete payment, observance and
performance of the Secured Obligations (as defined in the 2015 Security Agreement); and

 

WHEREAS, pursuant
to that certain securities purchase agreement, dated even date herewith (as may be amended, restated, supplemented, or otherwise
modified from time to time, including all schedules and exhibits thereto, collectively, the “2016 Purchase Agreement”),
by and among the Grantor and the investors listed on the Schedule of Buyers attached thereto (the “New Noteholders”),

WHEREAS, a majority

in respect of the Investment Related Property pledged hereunder which are received by the Grantor shall be held by the Grantor
in trust for the benefit of the Secured Parties segregated from the Grantor’s other property, and the Grantor shall deliver
it promptly to the Collateral Agent (on behalf of all Secured Parties) in the exact form received;

 

(iii)        The
Grantor shall promptly deliver to the Secured Parties a copy of each material notice or other written communication received by
it in respect of any Pledged Interests;

 

(iv)        The
Grantor shall not make or consent to any material amendment or other modification or waiver with respect to any Pledged Interests,
Pledged Operating Agreement, or Pledged Partnership Agreement or enter into any agreement or permit to exist any restriction with
respect to any Pledged Interests, in each case, that could reasonably be expected to materially adversely affect the Collateral
Agent or the Secured Parties;

 

(v)         The
Grantor agrees that it will cooperate with the Secured Parties in obtaining all necessary approvals and making all necessary filings
under federal and state law, and, upon the request of the Collateral Agent during the continuance of an Event of Default, under
foreign law, in connection with the Security Interests on the Investment Related Property pledged hereunder or any sale or transfer
thereof; and

 

(vi)        As
to all limited liability company or partnership interests issued under any Pledged Operating Agreement or Pledged Partnership Agreement,
the Grantor hereby represents, warrants and covenants that the Pledged Interests issued pursuant to such agreement (A) shall not
be dealt in or traded on securities exchanges or in securities markets, (B) will not constitute investment company securities,
and (C) will not be held by the Grantor in a securities account. In addition, none of the Pledged Operating Agreements, the
Pledged Partnership Agreements, or any other agreements governing any of the Pledged Interests issued under any Pledged Operating
Agreement or Pledged Partnership Agreement, shall provide that such Pledged Interests are securities governed by Article 8 of the
Uniform Commercial Code as in effect in any relevant jurisdiction.

 

    	 	12	 

     

    

  

(h)          Transfers
and Other Liens. The Grantor shall not (i) sell, lease, license, assign (by operation of law or otherwise), transfer or otherwise
dispose of, or grant any option with respect to, any of the Collateral, except for Permitted Transfers or as expressly permitted
by this Agreement and the other Transaction Documents, or (ii) except for Permitted Liens, create or permit to exist any Lien upon
or with respect to any of the Collateral without the consent of the Collateral Agent. The inclusion of Proceeds in the Collateral
shall not be deemed to constitute consent by any Secured Party to any sale or other disposition of any of the Collateral except
as expressly permitted in this Agreement or the other Transaction Documents. Notwithstanding anything contained in this Agreement
to the contrary, Permitted Liens (other than Permitted Liens granted to the Secured Parties) shall not be permitted with respect
to any Pledged Interests.

 

(i)          Preservation
of Existence.  The Grantor shall maintain and preserve its existence, rights and privileges, and become or remain
duly qualified and in good standing in each jurisdiction in which the character of the properties owned or leased by it or in which
the transaction of its business makes such qualification necessary, except where failure to be so qualified could not reasonably
be expected to have a Material Adverse Effect (as defined in the Securities Purchase Agreement).

 

(j)          Maintenance
of Properties. The Grantor shall maintain and preserve all of its properties which are reasonably necessary in the proper
conduct of its business in good working order and condition, ordinary wear and tear excepted.

 

(k)          Maintenance
of Insurance. The Grantor shall maintain insurance with responsible and reputable insurance companies or associations
(including, without limitation, comprehensive general liability, property, hazard, rent and business interruption insurance) with
respect to all of its assets and properties (including, without limitation, all real properties leased or owned by it and any and
all Inventory and Equipment) and business, in such amounts and covering such risks as is required by any governmental authority
having jurisdiction with respect thereto or as is carried generally in accordance with sound business practice by companies in
similar businesses similarly situated, in each case, reasonably acceptable to the Collateral Agent (on behalf of all Secured Parties).

 

    	 	13	 

     

    

  

(l)          Other
Actions as to Any and All Collateral. The Grantor shall promptly (and in any event within five (5) Business Days of acquiring
or obtaining such Collateral) notify the Secured Parties in writing upon (i) acquiring or otherwise obtaining any Collateral after
the date hereof consisting of Investment Related Property, Chattel Paper (electronic, tangible or otherwise), documents (as defined
in Article 9 of the Code), promissory notes (as defined in the Code) or instruments (as defined in the Code) collectively having
an aggregate value in excess of $100,000 or (ii) any amount payable under or in connection with any of the Collateral being or
becoming evidenced after the date hereof by any Chattel Paper, documents, promissory notes, or instruments and, in each such case
upon the request of the Collateral Agent (on behalf of all Secured Parties), promptly execute such other documents, or if applicable,
deliver such Chattel Paper, other documents or certificates evidencing any Investment Related Property and do such other acts or
things deemed reasonably necessary or desirable by the Collateral Agent (on behalf of all Secured Parties) to protect the Secured
Parties’ respective Security Interests therein.

 

7.          Relation
to Other Transaction Documents. In the event of any conflict between any provision in this Agreement and any provision in the
Securities Purchase Agreement or the Notes, such provision of the Securities Purchase Agreement or the Notes shall control, except
to the extent the applicable provision in this Agreement is more restrictive with respect to the rights of the Grantor or imposes
more burdensome or additional obligations on the Grantor, in which event the applicable provision in this Agreement shall control.

 

8.          Further
Assurances.

 

(a)          The
Grantor agrees that from time to time, at its own expense, it will promptly execute and deliver all further instruments and documents,
and take all further action, that may be reasonably necessary or that the Collateral Agent (on behalf of all Secured Parties) may
reasonably request, in order to perfect and protect the Security Interests granted or purported to be granted hereby or to enable
the Secured Parties to exercise and enforce their rights and remedies hereunder with respect to any of the Collateral.

 

(b)          The
Grantor authorizes the filing by the Collateral Agent (on behalf of all Secured Parties) of financing or continuation statements,
or amendments thereto, including, but not limited to, the recordation of the security interests granted hereunder in Patents, Trademarks
and Copyrights in the United States Patent and Trademark Office and the United States Copyright Office, and Grantor will execute
and deliver to the Collateral Agent such other instruments or notices, as may be reasonably necessary or as the Collateral Agent
may reasonably request, in order to perfect and preserve the Security Interests granted or purported to be granted hereby. Upon
the Satisfaction in Full of the Secured Obligations, the Collateral Agent shall (at Grantor’ expense) file a termination
statement and/or other necessary documents terminating and releasing any and all financing statements or Liens on the Collateral
pursuant to Section 24 within five (5) Business Days following a written request therefor from Grantor.

 

(c)          The
Grantor authorizes the Collateral Agent (on behalf of all Secured Parties) at any time and from time to time to file, transmit,
or communicate, as applicable, financing statements and amendments (i) describing the Collateral as “all assets of debtor”
or words of similar effect, (ii) describing the Collateral as being of equal or lesser scope or with greater detail, or (iii) that
contain any information required by part 5 of Article 9 of the Code for the sufficiency or filing office acceptance. The Grantor
also hereby ratifies any and all financing statements or amendments previously filed by the Collateral Agent in any jurisdiction.

 

    	 	14	 

     

    

  

(d)          Subject
to Section 8(b), the Grantor acknowledges that it is not authorized to file any financing statement or amendment or termination
statement with respect to any financing statement filed in connection with this Agreement without the prior written consent of
the Collateral Agent (on behalf of all Secured Parties), subject to the Grantor’s rights under Section 9-509(d)(2) of the
Code.

 

(e)          Upon
five (5) Business Day’s advance notice, the Grantor shall permit each Secured Party (at such Secured Party’s expense)
or its employees, accountants, attorneys or agents, access to examine and inspect any Collateral or any other property of the Grantor
at any time during ordinary business hours, but no more than once per calendar year unless an Event of Default has occurred and
is continuing.

 

9.          Collateral
Agent’s Right to Perform Contracts, Exercise Rights, etc. Upon the occurrence and during the continuance of an Event
of Default, the Collateral Agent (on behalf of all Secured Parties) (a) may proceed to perform any and all of the obligations of
the Grantor contained in any contract, lease, or other agreement and exercise any and all rights of the Grantor therein contained
as fully as the Grantor itself could, (b) shall have the right to use the Grantor’s rights under Intellectual Property Licenses
in connection with the enforcement of the Secured Parties’ rights hereunder, including the right to prepare for sale and
sell any and all Inventory and Equipment now or hereafter owned by the Grantor and now or hereafter covered by such licenses, and
(c) shall have the right to request that any Stock that is pledged hereunder be registered in the name of the Secured Parties or
any of their nominees.

 

10.         Collateral
Agent Appointed Attorney-in-Fact. The Grantor, on behalf of itself and each New Subsidiary of the Grantor, hereby irrevocably
appoints the Collateral Agent (on behalf of all Secured Parties) as the attorney-in-fact of the Grantor and each such New Subsidiary
upon the occurrence and during the continuance of an Event of Default. In the event the Grantor or any New Subsidiary fails to
execute or deliver in a timely manner any Transaction Document or other agreement, document, certificate or instrument which the
Grantor or New Subsidiary now or at any time hereafter is required to execute or deliver pursuant to the terms of the Securities
Purchase Agreement or any other Transaction Document, upon the occurrence and during the continuance of an Event of Default, the
Collateral Agent (on behalf of all Secured Parties) shall have full authority in the place and stead of the Grantor or New Subsidiary,
and in the name of the Grantor, such New Subsidiary or otherwise, to execute and deliver each of the foregoing. Without limitation
of the foregoing, upon the occurrence and during the continuance of an Event of Default, the Collateral Agent (on behalf of all
Secured Parties) shall have full authority in the place and stead of the Grantor and each New Subsidiary, and in the name of any
the Grantor, any such New Subsidiary or otherwise, to take any action and to execute any instrument which the Collateral Agent
(on behalf of all Secured Parties) may reasonably deem necessary or advisable to accomplish the purposes of this Agreement, including,
without limitation:

 

(a)          to
ask, demand, collect, sue for, recover, compromise, receive and give acquittance and receipts for moneys due and to become due
under or in connection with any Collateral of the Grantor or New Subsidiary;

 

    	 	15	 

     

    

  

(b)          to
receive and open all mail addressed to the Grantor or New Subsidiary and to notify postal authorities to change the address for
the delivery of mail to the Grantor or New Subsidiary to that of an address approved by the Collateral Agent (on behalf of all
Secured Parties);

 

(c)          to
receive, indorse, and collect any drafts or other instruments, documents, Negotiable Collateral or Chattel Paper;

 

(d)          to
file any claims or take any action or institute any proceedings which the Collateral Agent (on behalf of all Secured Parties) may
deem reasonably necessary or desirable for the collection of any of the Collateral of the Grantor or New Subsidiary or otherwise
to enforce the rights of the Secured Parties with respect to any of the Collateral; and

 

(e)          to
use any labels, Patents, Trademarks, trade names, URLs, domain names, industrial designs, Copyrights, customer lists, advertising
matter or other industrial or intellectual property rights, in advertising for the exclusive purpose of sale and selling Inventory
and other Collateral and to collect any amounts due under Accounts, contracts or Negotiable Collateral of the Grantor or New Subsidiary.

 

To the extent permitted by law, the Grantor
hereby ratifies, for itself and each New Subsidiary, all that such attorney-in-fact shall lawfully do or cause to be done by virtue
hereof. Such power-of-attorney granted pursuant to this Section 10 is coupled with an interest and shall be irrevocable until this
Agreement is terminated.

 

11.         Collateral
Agent May Perform. If the Grantor fails to perform any agreement contained herein, upon the occurrence and during the continuance
of an Event of Default, the Collateral Agent (on behalf of all Secured Parties) may perform, or cause performance of, such agreement,
and the reasonable expenses of the Collateral Agent incurred in connection therewith shall be payable by the Grantor.

 

12.         Collateral
Agent’s Duties; Bailee for Perfection. The powers conferred on the Collateral Agent hereunder are solely to protect the
Secured Parties’ respective interests in the Collateral and shall not impose any duty upon the Collateral Agent in favor
of the Grantor or any other Secured Party to exercise any such powers. Except for the safe custody of any Collateral in its actual
possession and the accounting for moneys actually received by it hereunder, the Collateral Agent shall not have any duty to the
Grantor or any other Secured Party as to any Collateral or as to the taking of any necessary steps to preserve rights against prior
parties or any other rights pertaining to any Collateral. The Collateral Agent shall be deemed to have exercised reasonable care
in the custody and preservation of any Collateral in its actual possession if such Collateral is accorded treatment substantially
equal to that which is accorded to its own property. The Collateral Agent agrees that, with respect to any Collateral at any time
or times in its possession and in which any other Secured Party has a Lien, the Collateral Agent shall be the bailee of each other
Secured Party solely for purposes of perfecting (to the extent not otherwise perfected) each other Secured Party’s Lien in
such Collateral, provided that the Collateral Agent shall not be obligated to obtain or retain possession of any such Collateral.

 

    	 	16	 

     

    

  

13.         Collection
of Accounts, General Intangibles and Negotiable Collateral. At any time upon the occurrence and during the continuation of
an Event of Default, the Collateral Agent (on behalf of all Secured Parties) may (a) notify Account Debtors of the Grantor that
the Accounts, General Intangibles, Chattel Paper or Negotiable Collateral have been assigned to the Collateral Agent (on behalf
of all Secured Parties) or that the Collateral Agent (on behalf of all Secured Parties) has a security interest therein, and (b)
collect the Accounts, General Intangibles and Negotiable Collateral directly, and any collection costs and expenses shall constitute
part of the Secured Obligations.

 

14.         Disposition
of Pledged Interests by Secured Parties. None of the Pledged Interests hereafter acquired on the date of acquisition thereof
will be registered or qualified under the various federal, state or other securities laws of the United States or any other jurisdiction,
and disposition thereof after an Event of Default may be restricted to one or more private (instead of public) sales in view of
the lack of such registration. The Grantor understands that in connection with such disposition, the Collateral Agent (on behalf
of all Secured Parties) may approach only a restricted number of potential purchasers and further understands that a sale under
such circumstances may yield a lower price for the Pledged Interests than if the Pledged Interests were registered and qualified
pursuant to federal, state and other securities laws and sold on the open market. The Grantor, therefore, agrees that: (a) if the
Collateral Agent (on behalf of all Secured Parties) shall, pursuant to the terms of this Agreement, sell or cause the Pledged Interests
or any portion thereof to be sold at a private sale, the Collateral Agent (on behalf of all Secured Parties) shall have the right
to rely upon the advice and opinion of any nationally recognized brokerage or investment firm (but shall not be obligated to seek
such advice and the failure to do so shall not be considered in determining the commercial reasonableness of such action) as to
the best manner in which to offer the Pledged Interest or any portion thereof for sale and as to the best price reasonably obtainable
at the private sale thereof; and (b) such reliance shall be conclusive evidence that the Collateral Agent has handled the disposition
in a commercially reasonable manner.

 

15.         Voting
Rights.

 

(a)          Upon
the occurrence and during the continuation of an Event of Default, (i) the Collateral Agent (on behalf of all Secured Parties)
may, at its option, and with two (2) Business Days prior notice to the Grantor, and in addition to all rights and remedies available
to the Secured Parties under any other agreement, at law, in equity, or otherwise, exercise all voting rights, and all other ownership
or consensual rights in respect of the Pledged Interests, but under no circumstances is the Collateral Agent obligated by the terms
of this Agreement to exercise such rights, and (ii) if the Collateral Agent (on behalf of all Secured Parties) duly exercises its
right to vote any of such Pledged Interests, the Grantor hereby appoints the Collateral Agent (on behalf of all Secured Parties)
as the Grantor’s true and lawful attorney-in-fact and IRREVOCABLE PROXY to vote such Pledged Interests in any manner that
the Collateral Agent (on behalf of all Secured Parties) deem advisable for or against all matters submitted or which may be submitted
to a vote of shareholders, partners or members, as the case may be. Such power-of-attorney granted pursuant to this Section 15
is coupled with an interest and shall be irrevocable until this Agreement is terminated.

 

    	 	17	 

     

    

 

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

 

16.         Remedies.
Upon the occurrence and during the continuance of an Event of Default:

 

(a)          The
Collateral Agent (on behalf of all Secured Parties) may exercise in respect of the Collateral, in addition to other rights and
remedies provided for herein, in the other Transaction Documents, or otherwise available to it, all the rights and remedies of
a secured party on default under the Code or any other applicable law. Without limiting the generality of the foregoing, the Grantor
expressly agrees that, in any such event, the Collateral Agent (on behalf of all Secured Parties) without any demand, advertisement,
or notice of any kind (except a notice specified below of time and place of public or private sale) to or upon the Grantor or any
other Person (all and each of which demands, advertisements and notices are hereby expressly waived to the maximum extent permitted
by the Code or by any other applicable law), may take immediate possession of all or any portion of the Collateral and (i) require
the Grantor to, and the Grantor hereby agrees that it will at its own expense and upon request of the Collateral Agent (on behalf
of all Secured Parties) promptly, assemble all or part of the Collateral as directed by the Collateral Agent (on behalf of all
Secured Parties) and make it available to the Collateral Agent (on behalf of all Secured Parties) at one or more locations where
the Grantor regularly maintains Inventory, and (ii) without notice except as specified below, sell the Collateral or any part thereof
in one or more parcels at public or private sale, at the Collateral Agent’s offices or elsewhere, for cash, on credit, and
upon such other terms as the Collateral Agent (on behalf of all Secured Parties) may deem commercially reasonable. The Grantor
agrees that, to the extent notice of sale shall be required by law, at least 10 Business Days’ notice of the time and place
of any public sale or the time after which any private sale is to be made shall constitute reasonable notification and specifically
such notice shall constitute a reasonable “authenticated notification of disposition” within the meaning of Section
9-611 of the Code. The Collateral Agent shall not be obligated to make any sale of Collateral regardless of notice of sale having
been given. The Collateral Agent (on behalf of all Secured Parties) may adjourn any public or private sale from time to time by
announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to
which it was so adjourned.

 

(b)          The
Collateral Agent (on behalf of all Secured Parties) is hereby granted a non-exclusive license or other right to use, without liability
for royalties or any other charge, the Grantor’s labels, Patents, Copyrights, rights of use of any name, trade secrets, trade
names, Trademarks, service marks and advertising matter, URLs, domain names, industrial designs, other industrial or intellectual
property or any property of a similar nature, whether owned by the Grantor or with respect to which the Grantor has rights under
license, sublicense, or other agreements (but only to the extent (i) such license, sublicense or agreement does not prohibit such
use by the Collateral Agent (on behalf of all Secured Parties), and (ii) the Grantor will not be in default under such license,
sublicense, or other agreement as a result of such use by the Collateral Agent (on behalf of all Secured Parties)), as it pertains
to the Collateral, for the exclusive purpose of preparing for sale, advertising for sale and effectuating the sale of any Collateral,
and the Grantor’s rights under all licenses and all franchise agreements shall inure to the benefit of the Collateral Agent
(on behalf of all Secured Parties).

 

    	 	18	 

     

    

  

(c)          Any
cash held by the Collateral Agent as Collateral and all proceeds received by the Collateral Agent in respect of any sale of, collection
from, or other realization upon all or any part of the Collateral shall be applied against the Secured Obligations in the order
set forth in Section 17 hereof. In the event the proceeds of Collateral are insufficient for the Satisfaction in Full of the Secured
Obligations (as defined below), the Grantor shall remain liable for any such deficiency.

 

(d)          The
Grantor hereby acknowledges that the Secured Obligations arose out of a commercial transaction, and agrees that if an Event of
Default shall occur and be continuing the Collateral Agent (on behalf of all Secured Parties) shall have the right to an immediate
writ of possession without notice of a hearing. The Collateral Agent (on behalf of all Secured Parties) shall have the right to
the appointment of a receiver for the properties and assets of the Grantor, and the Grantor hereby consents to such rights and
such appointment and hereby waives any objection it may have thereto or the right to have a bond or other security posted by the
Collateral Agent (on behalf of all Secured Parties).

 

(e)          The
Collateral Agent (on behalf of all Secured Parties) may, in addition to other rights and remedies provided for herein, in the other
Transaction Documents, or otherwise available to it under applicable law and without the requirement of notice to or upon the Grantor
or any other Person (which notice is hereby expressly waived to the maximum extent permitted by the Code or any other applicable
law), (i) with respect to the Grantor’s Deposit Accounts in which any Secured Party’s Liens are perfected by control
under Section 9-104 of the Code, instruct the bank maintaining such Deposit Account for the Grantor to pay the balance of such
Deposit Account to or for the benefit of the Collateral Agent (on behalf of all Secured Parties), and (ii) with respect to
the Grantor’s Securities Accounts in which any Secured Party’s Liens are perfected by control under Section 9-106 of
the Code, instruct the securities intermediary maintaining such Securities Account for the Grantor to (A) transfer any cash in
such Securities Account to or for the benefit of the Collateral Agent (on behalf of all Secured Parties), or (B) liquidate any
financial assets in such Securities Account that are customarily sold on a recognized market and transfer the cash proceeds thereof
to or for the benefit of the Collateral Agent (on behalf of all Secured Parties).

 

17.         Priority
of Liens; Application of Proceeds of Collateral. Each Secured Party hereby acknowledges and agrees that, notwithstanding the
time or order of the filing of any financing statement or other registration or document with respect to the Collateral and the
Security Interests, or any provision of this Agreement, any other Security Document, the Code or other applicable law, solely as
amongst the Secured Parties, the separate Security Interests of the Secured Parties shall have the same rank and priority; provided,
that, the foregoing shall not apply to any Security Interest of a Secured Party that is void or voidable as a matter of law. In
furtherance thereof, all proceeds of Collateral received by the Collateral Agent shall be applied as follows:

 

    	 	19	 

     

    

  

(a)          first,
ratably to pay any expenses due to the Collateral Agent (including, without limitation, the reasonable costs and expenses paid
or incurred to correct any default under or enforce any provision of the Transaction Documents, or after the occurrence and during
the continuance of any Event of Default in gaining possession of, maintaining, handling, preserving, storing, shipping, selling,
preparing for sale, or advertising to sell the Collateral, or any portion thereof, irrespective of whether a sale is consummated);

 

(b)          second,
to pay any indemnities then due to any of the Secured Parties under the Transaction Documents, until paid in full;

 

(c)          third,
ratably to pay any fees or premiums then due to any of the Secured Parties under the Transaction Documents, until paid in full;

 

(d)          fourth,
ratably to pay interest due in respect of the Secured Obligations then due to any of the Secured Parties, until paid in full;

 

(e)          fifth,
ratably to pay the principal amount of all Secured Obligations then due to any of the Secured Parties, until paid in full;

 

(f)          sixth,
ratably to pay any other Secured Obligations then due to any of the Secured Parties; and

 

(g)          seventh,
to Grantor or such other Person entitled thereto under applicable law.

 

18.         Remedies
Cumulative. Each right, power, and remedy of any Secured Party as provided for in this Agreement or in any other Transaction
Document or now or hereafter existing at law or in equity or by statute or otherwise shall be cumulative and concurrent and shall
be in addition to every other right, power, or remedy provided for in this Agreement or in the other Transaction Documents or now
or hereafter existing at law or in equity or by statute or otherwise, and the exercise or beginning of the exercise by any Secured
Party, of any one or more of such rights, powers, or remedies shall not preclude the simultaneous or later exercise by such Secured
Party of any or all such other rights, powers, or remedies.

 

19.         Marshaling.
No Secured Party shall be required to marshal any present or future collateral security (including but not limited to the Collateral)
for, or other assurances of payment of, the Secured Obligations or any of them or to resort to such collateral security or other
assurances of payment in any particular order, and all of its rights and remedies hereunder and in respect of such collateral security
and other assurances of payment shall be cumulative and in addition to all other rights and remedies, however existing or arising.
To the extent that it lawfully may, the Grantor hereby agrees that it will not invoke any law relating to the marshaling of collateral
which might cause delay in or impede the enforcement of any Secured Party’s rights and remedies under this Agreement or under
any other instrument creating or evidencing any of the Secured Obligations or under which any of the Secured Obligations is outstanding
or by which any of the Secured Obligations is secured or payment thereof is otherwise assured, and, to the extent that it lawfully
may, the Grantor hereby irrevocably waives the benefits of all such laws.

 

    	 	20	 

     

    

  

20.         Appointment
of Collateral Agent; Acknowledgment.

 

(a)          The
Secured Parties hereby appoint Robert Clifford to act as the initial collateral agent on behalf of all Secured Parties (the “Collateral
Agent”). Notwithstanding anything in this Agreement to the contrary, one or more Secured Parties (other than the then
Collateral Agent) holding a majority of the then aggregate outstanding principal balance of the Notes (excluding any Notes held
by the then acting Collateral Agent) may remove the then-acting Collateral Agent and appoint any other Secured Party to act as
the Collateral Agent under this Agreement. Upon such appointment such Secured Party shall act as Collateral Agent pursuant to the
terms of this Agreement.

 

(b)          No
Secured Party (which term, as used in this sentence, shall include reference to each Secured Party’s officers, directors,
employees, attorneys, agents and affiliates and to the officers, directors, employees, attorneys and agents of such Secured Party’s
affiliates) shall: (i) have any duties or responsibilities except those expressly set forth in this Agreement and the other
Security Documents or (ii) be required to take, initiate or conduct any enforcement action (including any litigation, foreclosure
or collection proceedings hereunder or under any of the other Security Documents). Without limiting the foregoing, no Secured Party
shall have any right of action whatsoever against any other Secured Party as a result of such Secured Party acting or refraining
from acting hereunder or under any of the Security Documents except as a result and to the extent of losses caused by such Secured
Party’s actual gross negligence or willful misconduct. No Secured Party assumes any responsibility for any failure or
delay in performance or breach by the Grantor or any other Secured Party of its obligations under this Agreement or any other Transaction
Document. No Secured Party makes to any other Secured Party any express or implied warranty, representation or guarantee with
respect to any Secured Obligations, Collateral, Transaction Document or the Grantor. No Secured Party nor any of its officers,
directors, employees, attorneys or agents shall be responsible to any other Secured Party or any of its officers, directors, employees,
attorneys or agents for: (i) any recitals, statements, information, representations or warranties contained in any of the
Transaction Documents or in any certificate or other document furnished pursuant to the terms hereof; (ii) the execution,
validity, genuineness, effectiveness or enforceability of any of the Transaction Documents; (iii) the validity, genuineness,
enforceability, collectability, value, sufficiency or existence of any Collateral, or the attachment, perfection or priority of
any Lien therein; or (iv) the assets, liabilities, financial condition, results of operations, business, creditworthiness
or legal status of the Grantor or any Account Debtor. No Secured Party nor any of its officers, directors, employees, attorneys
or agents shall have any obligation to any other Secured Party to ascertain or inquire into the existence of any default or Event
of Default, the observance or performance by the Grantor of any of its duties or agreements under any of the Transaction Documents
or the satisfaction of any conditions precedent contained in any of the Transaction Documents.

 

    	 	21	 

     

    

  

(d)          Each
Secured Party hereby acknowledges and represents that it has, independently and without reliance upon any other Secured Party,
and based upon such documents, information and analyses as it has deemed appropriate, made its own credit analysis of the Grantor
and its own decision to enter into the Transaction Documents and to purchase the Notes, and each Secured Party has made such
inquiries concerning the Transaction Documents, the Collateral and the Grantor as such Secured Party feels necessary and appropriate,
and has taken such care on its own behalf as would have been the case had it entered into the Transaction Documents without any
other Secured Party. Each Secured Party hereby further acknowledges and represents that the other Secured Parties have not made
any representations or warranties to it concerning the Grantor, any of the Collateral or the legality, validity, sufficiency or
enforceability of any of the Transaction Documents. Each Secured Party also hereby acknowledges that it will, independently and
without reliance upon the other Secured Parties, and based upon such financial statements, documents and information as it deems
appropriate at the time, continue to make and rely upon its own credit decisions in taking or refraining to take any other
action under this Agreement or the Transaction Documents. No Secured Party shall have any duty or responsibility to provide any
other Secured Party with any notices, reports or certificates furnished to such Secured Party by the Grantor or any credit or other
information concerning the affairs, financial condition, business or assets of the Grantor (or any of its affiliates) which may
come into possession of such Secured Party.

 

21.         Indemnity
and Expenses.

 

(a)          Without
limiting any obligations of the Grantor under the Securities Purchase Agreement, the Grantor agrees to indemnify all Secured Parties
from and against all claims, lawsuits and liabilities (including reasonable attorneys’ fees) arising out of or resulting
from this Agreement (including enforcement of this Agreement), except claims, losses or liabilities resulting from the gross negligence
or willful misconduct of the Secured Party seeking indemnification as determined by a final non-appealable order of a court of
competent jurisdiction. This provision shall survive the termination of this Agreement and the Transaction Documents and the Satisfaction
in Full of the Secured Obligations.

 

(b)          The
Grantor shall, upon demand, pay to the Collateral Agent all of the reasonable costs and expenses which the Collateral Agent may
incur in connection with the custody, preservation, use or operation of, or, upon an Event of Default, the sale of, collection
from, or other realization upon, any of the Collateral in accordance with this Agreement and the other Transaction Documents. The
Grantor shall, upon demand, pay to each Secured Party all of the reasonable costs and expenses which such Secured Party may incur
in connection with (i) the exercise or enforcement of any of the rights of such Secured Party hereunder or (ii) the failure by
the Grantor to perform or observe any of the provisions hereof.

 

    	 	22	 

     

    

  

22.         Merger,
Amendments; Etc. THIS AGREEMENT, TOGETHER WITH THE OTHER TRANSACTION DOCUMENTS, REPRESENTS THE FINAL AGREEMENT BETWEEN THE
PARTIES SOLELY WITH RESPECT TO THE SUBJECT MATTER HEREOF AND THEREOF AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS
OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN AGREEMENTS BETWEEN THE PARTIES. No provision of this Agreement
may be amended other than by an instrument in writing signed by the Grantor and the Collateral Agent, and any amendment to any
provision of this Agreement made in conformity with the provisions of this Section 22 shall be binding on all Secured Parties,
provided that no such amendment shall be effective to the extent that it (a) applies to less than all of the Secured Parties or
(b) imposes any obligation or liability on any Secured Party without such Secured Party’s prior written consent (which may
be granted or withheld in such Secured Party’s sole discretion). No waiver shall be effective unless it is in writing and
signed by an authorized representative of the waiving party, provided that the Collateral Agent may waive any provision of this
Agreement, and any waiver of any provision of this Agreement made in conformity with the provisions of this Section 22 shall be
binding on all Secured Parties, provided that no such waiver shall be effective to the extent that it (i) applies to less than
all the Secured Parties (unless a party gives a waiver as to itself only) or (ii) imposes any obligation or liability on any Secured
Party without such Secured Party’s prior written consent (which may be granted or withheld in such Secured Party’s
sole discretion).

 

23.         Addresses
for Notices. All notices and other communications provided for hereunder (a) shall be given in the form and manner set forth
in the Securities Purchase Agreement and (b) shall be delivered, (i) in the case of notice to the Grantor, by delivery of such
notice to the Grantor’s address specified in the Securities Purchase Agreement or at such other address as shall be designated
by the Grantor in a written notice to each of the Secured Parties in accordance with the provisions thereof, and (ii) in the case
of notice to any Secured Party, by delivery of such notice to such Secured Party at its address specified in the Securities Purchase
Agreement or at such other address as shall be designated by such Secured Party in a written notice to the Grantor and each other
Secured Party in accordance with the provisions thereof.

 

24.         Separate,
Continuing Security Interests; Assignments under Transaction Documents. This Agreement shall create a continuing security interest
in the Collateral in favor of the Collateral Agent on behalf of each Secured Party and shall (a) remain in full force and effect
until Satisfaction in Full of the Secured Obligations, (b) be binding upon the Grantor, and its permitted successors and permitted
assigns, and (c) inure to the benefit of, and be enforceable by, the Secured Parties and their respective successors, transferees
and assigns. Without limiting the generality of the foregoing clause (c), any Secured Party may, in accordance with the provisions
of the Transaction Documents, assign or otherwise transfer all or any portion of its rights and obligations under the Transaction
Documents to any other Person, and such other Person shall thereupon become vested with all the benefits in respect thereof granted
to such Secured Party herein or otherwise. Upon Satisfaction in Full of the Secured Obligations, the Security Interests granted
hereby shall terminate and all rights to the Collateral shall revert to the Grantor or any other Person entitled thereto. At such
time, the Collateral Agent and each Secured Party will authorize the filing of appropriate termination statements to terminate
such Security Interests. No transfer or renewal, extension, assignment, or termination of this Agreement or any other Transaction
Document, or any other instrument or document executed and delivered by the Grantor to any Secured Party nor any additional loans
made by any Secured Party to the Grantor, nor the taking of further security, nor the retaking or re-delivery of the Collateral
to the Grantor, or any of them, by any Secured Party, nor any other act of the Secured Parties, or any of them, shall release the
Grantor from any obligation, except a release or discharge executed in writing by all Secured Parties. No Secured Party shall by
any act, delay, omission or otherwise, be deemed to have waived any of its rights or remedies hereunder, unless such waiver is
in writing and signed by such Secured Party and then only to the extent therein set forth. A waiver by any Secured Party of any
right or remedy on any occasion shall not be construed as a bar to the exercise of any such right or remedy which such Secured
Party would otherwise have had on any other occasion.

 

    	 	23	 

     

    

  

25.         Governing
Law; Jurisdiction; Service of Process; Jury Trial. All questions concerning the construction, validity, enforcement and interpretation
of this Agreement shall be governed by the internal laws of the State of New York, without giving effect to any choice of law or
conflict of law provision or rule (whether of the State of New York or any other jurisdictions) that would cause the application
of the laws of any jurisdictions other than the State of New York. Each party hereby irrevocably submits to the exclusive jurisdiction
of the state and federal courts sitting in The City of New York, Borough of Manhattan, for the adjudication of any dispute hereunder
or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees
not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court,
that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such suit, action or proceeding is
improper; provided, however, any suit seeking enforcement against any Collateral or other property may be brought,
at any Secured Party’s option, in the courts of any jurisdiction where such Secured Party elects to bring such action or
where such Collateral or other property may be found. Each party hereby irrevocably waives personal service of process and consents
to process being served in any such suit, action or proceeding by mailing a copy thereof to such party at the address for such
notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice
thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law.
EACH PARTY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE TO, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION
OF ANY DISPUTE HEREUNDER OR IN CONNECTION WITH OR ARISING OUT OF THIS AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREBY. 

 

26.         Miscellaneous.

 

(a)          This
Agreement may be executed in two or more counterparts, all of which shall be considered one and the same agreement and shall become
effective when counterparts have been signed by each party and delivered to the other party. In the event that any signature is
delivered by facsimile transmission or by an e-mail which contains a portable document format (.pdf) file of an executed signature
page, such signature page shall create a valid and binding obligation of the party executing (or on whose behalf such signature
is executed) with the same force and effect as if such signature page were an original thereof. Any party delivering an executed
counterpart of this Agreement by facsimile or other electronic method of transmission also shall deliver an original executed counterpart
of this Agreement but the failure to deliver an original executed counterpart shall not affect the validity, enforceability, and
binding effect of this Agreement. The foregoing shall apply to each other Security Document mutatis mutandis.

 

    	 	24	 

     

    

  

(b)          Any
provision of this Agreement which is prohibited or unenforceable shall be ineffective to the extent of such prohibition or unenforceability
without invalidating the remaining provisions hereof in that jurisdiction or affecting the validity or enforceability of such provision
in any other jurisdiction.

 

(c)          Headings
used in this Agreement are for convenience only and shall not be used in connection with the interpretation of any provision hereof.

 

(d)          The
pronouns used herein shall include, when appropriate, either gender and both singular and plural, and the grammatical construction
of sentences shall conform thereto.

 

(e)          The
language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no
rules of strict construction will be applied against any party. For clarification purposes, the Recitals are part of this Agreement.

 

(f)          Unless
the context of this Agreement or any other Transaction Document clearly requires otherwise, references to the plural include the
singular, references to the singular include the plural, the terms “includes” and “including” are not limiting,
and the term “or” has, except where otherwise indicated, the inclusive meaning represented by the phrase “and/or.”
The words “hereof,” “herein,” “hereby,” “hereunder,” and similar terms in this
Agreement or any other Transaction Document refer to this Agreement or such other Transaction Document, as the case may be, as
a whole and not to any particular provision of this Agreement or such other Transaction Document, as the case may be. Section,
subsection, clause, schedule, and exhibit references herein are to this Agreement unless otherwise specified. Any reference in
this Agreement or in any other Transaction Document to any agreement, instrument, or document shall include all alterations, amendments,
changes, extensions, modifications, renewals, replacements, substitutions, joinders, and supplements, thereto and thereof, as applicable
(subject to any restrictions on such alterations, amendments, changes, extensions, modifications, renewals, replacements, substitutions,
joinders, and supplements set forth herein). “Satisfaction in Full of the Secured Obligations” shall mean the
indefeasible payment in full in cash and discharge, or other satisfaction in accordance with the terms of the Transaction Documents
(including, without limitation, conversion of the Notes into equity of the Company) and discharge, of all Secured Obligations in
full. Any reference herein to any Person shall be construed to include such Person’s permitted successors and permitted assigns.
Any requirement of a writing contained herein or in any other Transaction Document shall be satisfied by the transmission of a
Record and any Record so transmitted shall constitute a representation and warranty as to the accuracy and completeness of the
information contained therein.

dollar amounts referred to in this Agreement and the other Transaction Documents are in United States Dollars (“U.S. Dollars”),
and all amounts owing under this Agreement and all other Transaction Documents shall be paid in U.S. Dollars. All amounts denominated
in other currencies shall be converted into the U.S. Dollar equivalent amount in accordance with the Exchange Rate on the date
of calculation. “Exchange Rate” means, in relation to any amount of currency to be converted into U.S.
Dollars pursuant to this Agreement, the U.S. Dollar exchange rate as published in The Wall Street Journal on the relevant date
of calculation.

 

(h)          For
the avoidance of doubt, this Agreement hereby amends and restates the 2015 Security Agreement in its entirety.

RECITALS

 

A.           On
March 17, 2015, the Company issued senior secured convertible notes having an aggregate principal amount of $14,750,000 (the “2015

and the 2015 Convertible Note, with the holders of the 2016 Convertible Notes. In addition, the Company proposes to amend
and restate the Security Agreement and Registration Rights Agreement and enter into the amended and restated Security Agreement
and Registration Rights Agreement with the holders of the 2016 Convertible Notes.

D.           The

Convertible Notes and allow the 2016 Convertible Notes to be pari passu in all respects with the 2015 Convertible Notes,
(ii) amend and restate the Security Agreement and Registration Rights Agreement and (iii) make certain amendments to the 2015 Convertible
Notes and Securities Purchase Agreement.
