(b) No Public Sale
or Distribution. Such Buyer (i) is acquiring its Shares, and (ii) upon conversion of its Shares will acquire the Conversion
Shares issuable upon conversion thereof, in each case, for its own account and not with a view towards, or for resale in connection
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.


 


(c) Accredited Investor
Status. Such Buyer is an “accredited investor” as that term is defined in Rule 501(a) of Regulation D.


 


(d) Reliance on Exemptions.
Such Buyer understands that the Securities are being offered and sold to it in reliance on specific exemptions 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

such Buyer set forth herein in order to determine the availability of such exemptions and the eligibility of such Buyer to acquire
the Securities.

Such Buyer and its advisors, if any, have been furnished with the Company’s private placement memorandum, dated March 7,
2018, (the “Private Placement Memorandum”), and 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. Such Buyer and its advisors, if any, have been afforded the opportunity to ask questions of the Company. Such Buyer understands
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, and it
is not relying on any statements or representations of the Company or its agents for legal advice with respect to this investment
or the transactions contemplated by this Agreement. Such Buyer believes that it has received all the information such Buyer considers
necessary or appropriate for deciding whether to purchase the Securities. Such Buyer understands that such discussions, as well
as any information provided by the Company, including the Private Placement Memorandum, were intended to describe certain aspects
of the Company’s business and prospects, but were not necessarily a thorough or exhaustive description. The foregoing provisions
of this Section 2(e), however, do not limit or modify the representations and warranties of the Company in Section 3 of this Agreement
or the right of the Buyers to rely thereon.

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 in the
Securities nor have such authorities passed upon or endorsed the merits of the offering of the Securities.


 


(g) Transfer or Resale.
Such Buyer understands that except as provided in the Registration Rights Agreement or Section 4(g) hereof: (i) the Securities
have not been and are not being registered under the 1933 Act or any state securities laws, and may not be offered 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.

THE COMPANY.

and is in good standing in every jurisdiction in which its ownership of property or the nature of the business conducted by it
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

Person or (II) controls or operates all or any part of the business, operations or administration of such Person, and each of the

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.

capacity of an arm’s length purchaser with respect to the Transaction Documents and the transactions contemplated hereby
and thereby and that no Buyer is (i) an “affiliate” (as defined in Rule 144) of the Company or (ii) to its knowledge,
a “beneficial owner” of more than ten percent (10%) of the shares of Common Stock (as defined for purposes of Rule
13d-3 of the Securities and Exchange Act of 1934 Act, as amended (“1934 Act”)). The Company further 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

the Company has not engaged any placement agent or other broker or dealer in connection with the offer or sale of the Securities.


 




    6


     


    

 


(h) No Integrated
Offering. None of the Company or, to the Company’s 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 (other than
any required approval of holders of a majority of the outstanding common stock of the Company received before the Initial Closing)
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 Shares in accordance with this Agreement
and the Certificate is absolute and unconditional, regardless of the dilutive effect that such issuance may have on the ownership
interests of other stockholders of the Company.


 


(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 or the laws of the jurisdiction of its incorporation or otherwise 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.
The Private Placement Memorandum provided to the Buyers in connection with the sale of the Shares, 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. 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 Private Placement Memorandum, there has been no material adverse change and
no material adverse development in the business, assets, liabilities, properties, operations (including results thereof), condition
(financial or otherwise) or prospects of the Company. Since the date of the Company’s Private Placement Memorandum, the Company

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 their respective 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 each 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), (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

adverse effect on any Buyer’s investment hereunder or (ii) could have a Material Adverse Effect.

(s) Indebtedness
and Other Contracts. The Company, except as disclosed on Schedule 3(s) attached to the Disclosure Letter or in the Private
Placement Memorandum, (i) has no outstanding Indebtedness (as defined below), (ii) is not a party to any contract, agreement or
instrument, the violation of which, or default under which, by the other party(ies) to such contract, agreement or instrument could
reasonably be expected to result in a Material Adverse Effect, (iii) is not in violation of any term of, or in default under, any
contract, agreement or instrument relating to any Indebtedness, except where such violations and defaults would not result, individually
or in the aggregate, in a Material Adverse Effect, or (iv) is not a party to any contract, agreement or instrument relating to
any Indebtedness, the performance of which, in the judgment of the Company’s officers, has or is expected to have a Material
Adverse Effect. “Indebtedness” of any Person means, without duplication (A) all indebtedness for borrowed
money, (B) all obligations issued, undertaken or assumed as the deferred purchase price of property or services (including, without
limitation, “capital leases” in accordance with generally accepted accounting principles) (other than trade payables
entered into in the ordinary course of business), (C) all reimbursement or payment obligations with respect to letters of credit,
surety bonds and other similar instruments, (D) all obligations evidenced by notes, bonds, debentures or similar instruments, including
obligations so evidenced incurred in connection with the acquisition of property, assets or businesses, (E) all indebtedness created
or arising under any conditional sale or other title retention agreement, or incurred as financing, in either case with respect
to any property or assets acquired with the proceeds of such indebtedness (even though the rights and remedies of the seller or
bank under such agreement in the event of default are limited to repossession or sale of such property), (F) all monetary obligations
under any leasing or similar arrangement which, in connection with generally accepted accounting principles, consistently applied
for the periods covered thereby, is classified as a capital lease, (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, pledge, charge, security interest or other encumbrance upon or in any property or assets (including accounts
and contract rights) owned by any Person, even though the Person which owns such assets or property has not assumed or become liable
for the payment of such indebtedness, and (H) all Contingent Obligations in respect of indebtedness or obligations of others of
the kinds referred 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 to the obligee of such liability that such liability will be paid or discharged, or that any agreements
relating thereto will be complied with, or that the holders of such liability will be protected (in whole or in part) against loss
with respect thereto. “Person” means an individual, a limited liability company, a partnership, a joint
venture, a corporation, a trust, an unincorporated organization, any other entity and a government or any department or agency
thereof.

or directors which is outside of the ordinary course of business or individually or in the aggregate material to the Company. There

Act) or other key employee of the Company has notified the Company that such officer intends to leave the Company or otherwise
terminate such officer’s employment with the Company. To the Company’s knowledge, no executive officer or other key
employee of the Company is, or is now expected to be, in violation 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.

has no knowledge of any infringement by the Company of Intellectual Property Rights of others. There is no claim, action or proceeding
being made or brought, or to the knowledge of the Company, being threatened, against the Company regarding their Intellectual Property

in good faith and (iii) has set aside on its books provision reasonably adequate for the payment of all taxes for periods subsequent
to the periods to which such returns, reports or declarations apply. There are no unpaid taxes in any material amount claimed to
be due by the taxing authority of any jurisdiction, and the officers of the Company know of no basis for any such claim. The Company

Internal Revenue Code of 1986, as amended.

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 Shares for general corporate purposes, as set forth in the Private Placement
Memorandum; provided, however, that the Company shall not use any of the proceeds to make or repay loans to any officer or director

(e) Listing.
In connection with the Company becoming 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

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

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.


 


(h) Reservation of
Shares. The Company shall take all action necessary to at all times have authorized, and reserved for the purpose of issuance,

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.


 


(j) Subsequent Placements.

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 of the Company, including without limitation any shares of Series A Preferred Stock
that remain authorized and unissued following the termination of the offering pursuant to this Agreement (“Subsequent
Placement”). The Required Buyers Consent may include the Required Buyers requiring the Company to provide additional
rights to the Holders in connection with any Subsequent Placement including, without limitation, right of participation, increase
in the amount of the Stated Value (as defined in the Certificate) and additional redemption rights. Notwithstanding anything to
the contrary herein, the term “Subsequent Placement” shall not include (i) a firm commitment underwritten
initial public offering through a registered broker-dealer (an “IPO”), (ii) with the prior written consent
of Liquid Venture Partners, LLC, an affiliate of the Placement Agent (“LVP”), a placement (or series
of placements), based on a pre-issuance valuation of the Company of at least the product of: (A) the total number of issued and
outstanding Common Stock and Common Stock Equivalents (on a converted basis) immediately prior to the Subsequent Placement issuance,
multiplied by (B) the product of: (x) the Per Share Purchase Price, multiplied by (y) two, and in which in the aggregate gross
proceeds to the Company do not exceed $2 million, or (iii) the issuance of equity or equity linked securities, other than Series
A Preferred Stock, based on a pre-issuance valuation of the Company of at least the product of: (A) the total number of issued
and outstanding Common Stock and Common Stock Equivalents (on a converted basis) immediately prior to the Subsequent Placement
issuance, multiplied by (B) the product of: (x) the Per Share Purchase Price, multiplied by (y) two, to one or more of the Company’s
strategic partners and/or licensors in consideration of non-cash assets or license rights from the strategic partner or licensor,
which issuances in the aggregate shall not exceed securities worth $5 million. All shares of Common Stock issued or issuable pursuant
to the securities of the Company issued under this Section 4(j) shall be subject to the 12 month lock-up set forth in Section 4(t).
“Common Stock Equivalents” means any securities of the Company which would entitle the holder thereof

(k) Change of Control.
Prior to an IPO, the Company may not effect a Change of Control without the prior written consent of the Required Buyers. “Change
of Control” means (x) the acquisition of the Company by another entity by means of any transaction (including, without
limitation, any stock acquisition, reorganization, merger or consolidation) that contemplates an enterprise value of the Company
of less than the product of: (A) the total number of issued and outstanding Common Stock and Common Stock Equivalents (on a converted
basis) immediately prior to the effective date of the Change of Control, multiplied by (B) the product of: (i) the Per Share Purchase
Price, multiplied by (ii) two, or (y) a sale of all or substantially all of the assets of the Company (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 for an aggregate purchase price of less than the product of:
(A) the total number of issued and outstanding Common Stock and Common Stock Equivalents (on a converted basis) immediately prior
to the effective date of the Change of Control, multiplied by (B) the product of: (i) the Per Share Purchase Price, multiplied
by (ii) two.). In the event of a Change of Control, each Buyer shall have the right but not the obligation, by providing a written
request to the Company prior to the effective date of the Change of Control event, to require the Company to purchase some or all
of such Buyer’s Shares outstanding at a purchase price per Share equal to the product of: (A) two, multiplied by (B) the
Per Share Purchase Price (the “Put Option Right”). The Company shall not enter into any Change of Control
transaction pursuant to which it would be unable to purchase back all of the issued and outstanding Shares then held by the Buyers
(including their assignees) at the time of proposed Change of Control event pursuant to a full exercise by all of the Buyers (including
their assignees) of their Put Option Right.


 


(l) Variable Rate
Transaction. Notwithstanding anything in this Agreement to the contrary, until the later of none of the Shares not having been
converted to Conversion Shares or 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 (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). Each Buyer 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. Notwithstanding the foregoing, the offer or sale of the Series A Preferred
Stock shall not be deemed to be a Variable Rate Transaction.


 




    16


     


    

 


(m) 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.


 


(n) Restriction on
Redemption and Cash Dividends. So long as any Shares are outstanding and have not been converted to Conversion Shares, the
Company shall not, directly or indirectly, redeem, 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.

hundred twenty (120) days of the Effective Date, have a board of directors and committees thereof that conform to the requirements
of Nasdaq Listing Rule 5605 applicable to smaller reporting companies. So long as the Shares are outstanding, LVP shall have the
right to advise and require its written consent on all board of director nominees, provided however, such consent shall not be
unreasonably withheld. Subject to any legal rights under Delaware law of the stockholders, the board of directors of the Company
and committees thereof shall conform to Nasdaq Listing Rule 5605 and the foregoing sentence for so long as any Shares are outstanding
and have not been converted to Conversion Shares, except as approved by LVP, which approval may be withheld in its discretion and
subject to reasonable conditions, including the requirement of additional independent directors.


 


(q) Intellectual
Property Strategy. Within three months following the Effective Date, the Company will adopt an intellectual property strategy
reasonably acceptable to LVP, and provide a written summary of the strategy to the Placement Agent.


 


(r) Incentive Equity.
The Company has adopted an incentive stock or equity award plan (the “Plan”) that is attached hereto
as Exhibit E and which provides for awards of up to 1,630,000 shares of Common Stock. As of the Effective Date, 1,630,000
shares of Common Stock remain eligible for issuance under the Plan for future issuance (the “Reserved Shares”).
The Company hereby agrees that prior to the closing of the IPO, the Company shall only issue “Options” (as defined
in the Plan) under the Plan and that the exercise price per share for any Options issued prior to the final Closing shall not be
less than the Per Share Purchase Price. Following the completion of the Offering, up to and including the date of an IPO, the Reserved
Shares shall not represent in excess of fifteen percent (15%) of the number of fully diluted shares of Common Stock. The Plan will
not be amended to increase the number of shares subject thereto until the Company becomes a Reporting Company or with the approval
of the Required Buyers. By each Buyer’s execution and delivery of this Agreement, each Buyer hereby consents to the adoption
by the Company of the Plan attached hereto as Exhibit E as of the date each Buyer acquires the Shares purchased by each
such Buyer.


 


(s) Independent Accountants.
Within three months after the date of initial issuance of the Shares, the Company will engage independent certified public accountants,
which firm is actively registered with the PCAOB, to perform an audit of the financial statements that would be necessary and sufficient
to meet the filing requirements of a registration statement for the registration of securities of the Company either for issuance
by the Company or resale of the Conversion Shares, which audit will be completed no later than nine (9) months after the date of
the initial issuance of the Shares.


 




    17


     


    

 


(t) Lock Up.
In connection with the IPO, the Company will use its best efforts to obtain lock-up agreements from all officers, directors and
employees of the Company and Parent, any direct or beneficial owner of five percent (5%) or more of the Common Stock (excluding
any Conversion Shares for purposes of calculating the five percent (5%)), and National Securities Corporation (“NSC”)
and any beneficial holders of shares of Common Stock who are affiliates of NSC in respect of shares of Common Stock issued upon
exercise of any warrants issued in connection with the offering by the Company of the Shares (the “Financing Shares”)
(for clarity, the lock up for NSC and its affiliates will not apply to any other shares of Common Stock, including any shares of
Common Stock acquired in the public markets); the foregoing lock up to extend for a period of 12 months after the effective date
of the registration statement for the IPO.


 


(u) Investor Market
Stand-Off. In connection with the IPO, if any, each Buyer hereby agrees that, for one hundred eighty (180) days from the effective
date of such registration (the “Restricted Period”), it will not (i) offer, pledge, sell, contract to
sell, sell 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; 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 Common Stock or any securities convertible
into or exercisable or exchangeable for any Common 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. In order to enforce the restrictions agreed to by Buyer in this Section 4(u), 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(u).


 


(v) IPO Commitment.
The Company shall, no later than the date that is seven (7) months following the final Closing Date of the Offering, subject to
extension upon the prior written approval of the Required Holders (such date, hereinafter, the “Form S-1 Filing Due
Date”), file with or submit confidentially to the SEC a registration statement on Form S-1 (or any successor from
thereto) to register and sell Common Stock in an IPO and complete the IPO no later than the date that is the 14 month anniversary
of the Form S-1 Filing Due Date, subject to extension upon the prior written approval of the Required Holders.


 


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 Shares and, if issued, the Conversion Shares in which the Company shall
record the name and address of the Person in whose name the Shares and/or Conversion Shares have been issued (including the name
and address of each transferee), the aggregate number of Shares or 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.


 




    18


     


    

 


(b) Transfer Agent
Instructions. If a Buyer effects a sale, assignment or transfer of the Conversion Shares, the Company shall permit the transfer
and shall promptly instruct its transfer agent to issue one or more certificates or 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 stock certificates):


 


[NEITHER THE ISSUANCE AND SALE
OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE 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.


 




    19


     


    

 


(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) while a registration statement (including a 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 (assuming the transferor is not an affiliate of the
Company), (iii) if such Securities are eligible to be sold, assigned or transferred under Rule 144 (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 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 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 a reasonable description of the authority Buyer is relying upon). 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 two (2) 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 such Buyer’s or its designee’s balance account 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 Buyer, a certificate representing such Securities
that is free from all restrictive and other legends, registered in the name of such Buyer or its designee (the date by which such
credit is so required to be made to the balance account of such Buyer’s or such Buyer’s nominee with DTC or such certificate
is required to be delivered to such Buyer pursuant to the foregoing is referred to herein as the “Required Delivery
Date”).


 


(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 Buyer 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 Buyer’s
or such Buyer’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, then, in addition to all other remedies available to such Buyer, 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 the shares of
Common Stock so purchased (including brokerage commissions and other out-of-pocket expenses, if any) (the “Buy-In Price”),
at which point the Company’s obligation to so deliver such certificate or credit such Buyer’s balance account shall
terminate and such shares shall be cancelled, or (y) promptly honor its obligation to so deliver to such Buyer a certificate or
certificates or credit such Buyer’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 Buyer by the Required Delivery Date multiplied by (B) the lowest closing sale price of the Common Stock on any
Business Day during the period commencing on the date of the delivery by such Buyer to the Company of the applicable Conversion
Shares and ending on the date of such delivery and payment under this clause (y).

    23


     


    

 


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.


 


(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.


 




    24


     


    

 


(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, 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, and 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 Shares. 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 having Purchase Prices in the aggregate that are at least equal to a majority of the aggregate Purchase Price for
all Buyers.

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 of 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 Shares
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, (ii) any transaction
financed or to be financed in whole or in part, directly or indirectly, with the proceeds of the issuance of the Securities, or
(iii) the status of such Buyer or holder of the Securities either as an investor in the Company pursuant to 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.


 




    27


     


    

 


(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.


 


(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.


 




    28


     


    

 


(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.

declared by the Board of Directors.

    38


     


    

 


5. Registration of
Series A Preferred Stock. The Corporation or its transfer agent (the “Transfer Agent”) shall register shares
of the Series A Preferred Stock, upon records to be maintained by the Corporation or its Transfer Agent, as the case may be, for
that purpose (the “Series A Preferred Stock Register”), in the name of the record Holders thereof from time
to time. To the fullest extent permitted by law, the Corporation may deem and treat the registered Holder of shares of Series A
Preferred Stock as the absolute owner thereof for the purpose of any conversion hereof or any distribution to such Holder, and
for all other purposes, absent actual written notice to the contrary from the registered Holder.


 


6. Registration of
Transfers. The Corporation or its Transfer Agent shall register the transfer of any shares of Series A Preferred Stock in the
Series A Preferred Stock Register, upon surrender of certificates evidencing such shares to the Corporation at its address specified
in Section 15 of this Certificate of Incorporation. Upon any such registration or transfer, a new certificate evidencing the shares
of Series A Preferred Stock so transferred shall be issued to the transferee and a new certificate evidencing the remaining portion
of the shares not so transferred, if any, shall be issued to the transferring Holder; provided that if the Corporation does not
so record an assignment, transfer or sale (as the case may be) within two (2) Business Days of its receipt of such a request, then
the Series A Preferred Stock Register shall be automatically updated to reflect such assignment, transfer or sale (as the case
may be).


 


7. Liquidation.
In the event of any liquidation, dissolution or winding up of the Corporation, either voluntary or involuntary (a “Liquidation
Event”), the Holders shall be entitled to receive, prior and in preference to any distribution of any of the assets or
surplus funds of the Corporation to the holders of Junior Securities by reason of their ownership thereof, an amount per share
in cash equal to the greater of (x) the Stated Value for each share of Series A Preferred Stock then held by them (as adjusted
for any stock split, stock dividend, stock combination or other similar transactions with respect to the Series A Preferred Stock),
plus all accrued and unpaid dividends on such Series A Preferred Stock as of the date of such event, or (y) the amount payable
per share of Common Stock that such Holder of Series A Preferred Stock would have received if such Holder had converted to Common
Stock immediately prior to the Liquidation Event all of the shares of Series A Preferred Stock then held by such Holder together
with all accrued but unpaid dividends on such Series A Preferred Stock as of the date of such event (the “Series A Stock
Liquidation Preference”). If, upon the occurrence of a Liquidation Event, the funds thus distributed among the Holders
shall be insufficient to permit the payment to such Holders of the full Series A Stock Liquidation Preference, then the entire
assets and funds of the Corporation legally available for distribution shall be distributed ratably among the Holders in proportion
to the aggregate Series A Stock Liquidation Preference that would otherwise be payable to each of such Holders. Such payment shall
constitute payment in full to the holders of the Series A Preferred Stock upon the Liquidation Event. After such payment shall
have been made in full, or funds necessary for such payment shall have been set aside by the Corporation in trust for the account
of the Holders, so as to be immediately available for such payment, such Holders shall be entitled to no further participation
in the distribution of the assets of the Corporation. The sale of all or substantially all of the assets of the Corporation, or
merger, tender offer or other business combination to which the Corporation is a party in which the voting stockholders of the
Corporation prior to such merger, tender offer or other business combination do not own a majority of the voting securities of
the resulting entity or by which any person or group acquires beneficial ownership of 50% or more of the voting securities of the
Corporation or resulting entity shall, for the purposes of this Certificate of Incorporation, be deemed to be a Liquidation Event.


 




    39


     


    

 


8. Conversion.
The Series A Preferred Stock held by a Holder may be converted into validly issued, fully paid and non-assessable shares of
Common Stock on the terms and conditions set forth in this Section 8.


 


(a) Mandatory
Conversion.


 


(i) IPO.
Upon consummation of the IPO, each share of Series A Preferred Stock shall automatically convert, through no further action on
the part of the Corporation or the Holder, into that number of shares of Common Stock equal to the quotient of (i) the Conversion
Amount divided by (ii) the Conversion Price. For the purpose of this Section 8(a)(i), the “Conversion Price”
shall be equal to fifty percent (50%) of the IPO Price to Public (rounded to two decimal places).


 


(ii) Financing.
Upon consummation of a Subsequent Placement approved by the Required Holders pursuant to Section 4(j) of the Securities Purchase
Agreement, each share of Series A Preferred Stock shall automatically convert, through no further action on the part of the Corporation
or the Holder, 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 8(a)(ii), the “Conversion Price” shall be equal to fifty
percent (50%) of the purchase price of the securities being sold by the Corporation in such Subsequent Placement (rounded to two
decimal places).


 


(b) Optional
Conversion. At any time after the Issuance Date and until ten (10) calendar days prior to the consummation of the IPO
(as set forth in the IPO Notice), each Holder shall be entitled to convert its Series A Preferred Stock 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 8(b), the “Conversion Price” shall be equal to $2.50, as adjusted for stock splits, stock dividends,
stock combinations, recapitalizations, or the like that occur after the Issuance Date in accordance with Section 13.


 


(c) Mechanics
of Conversion.


 


(i) Mechanics
of Mandatory Conversion. Upon the occurrence of an event specified in Section 8(a)(i) or 8(a)(ii) above, the outstanding shares
of Series A Preferred Stock shall be converted into Common Stock automatically without the need for any further action by the Holders
and whether or not the certificates representing such shares are surrendered to the Corporation or its Transfer Agent; provided,
however, that the Corporation shall not be obligated to issue certificates evidencing the shares of Common Stock issuable upon
such conversion unless the certificates evidencing such shares of Series A Preferred Stock are either delivered to the Corporation
or its transfer agent as provided below, or the Holder notifies the Corporation or its Transfer Agent that such certificates have
been lost, stolen or destroyed and executes an agreement satisfactory to the Corporation to indemnify the Corporation from any
loss incurred by it in connection with such certificates. Upon the occurrence of such automatic conversion of the Series A Preferred
Stock, the Holders shall surrender the certificates representing such shares at the office of the Corporation or the Transfer Agent.
Thereupon, there shall be issued and delivered to such holder promptly at such office and in its name as shown on such surrendered
certificate or certificates a certificate or certificates for the number of shares of Common Stock into which the shares of Series
A Preferred Stock surrendered were convertible on the date on which such automatic conversion occurred.


 


(ii) Mechanics
of Optional Conversion. To convert Series A Preferred stock pursuant to Section 8(b) above into shares of Common Stock on any
date (a “Conversion Date”), the Holder shall surrender the certificate or certificates therefor, duly endorsed,
at the office of the Corporation or the Transfer Agent, or notify the Corporation or its Transfer Agent that such certificates
have been lost, stolen or destroyed and execute an agreement satisfactory to the Corporation to indemnify the Corporation from
any loss incurred by it in connection with such certificates, and shall deliver at such office a copy of a properly and fully-completed
and executed notice of conversion in the form attached hereto as Exhibit A (the “Conversion Notice”).
Thereupon, the Corporation shall promptly issue and deliver to such Holder a certificate or certificates for the number of shares
of Common Stock to which such holder is entitled upon such conversion. Such conversion shall be deemed to have been made immediately
prior to the close of business on the date of such surrender of the certificate or certificates representing the shares of Series
A Preferred Stock to be converted, and the person entitled to receive the shares of Common Stock issuable upon such conversion
shall be treated for all purposes as the record holder of such shares of Common Stock on such date.


 




    40


     


    

 


(d) No
Fractional Shares; Transfer Taxes. The Corporation 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 Corporation shall round such fraction
of a share of Common Stock up to the nearest whole share. The Corporation 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.


 


(e) Announcement
of Initial Public Offering. After such time as the Corporation determines that it will consummate an IPO, it shall send a notice
to the Holders (the “IPO Notice”) of the proposed consummation date of the IPO (the expected date of such consummation
is the “Announced IPO Date”), but such IPO Notice shall be dispatched in any event no later than ten (10) calendar
days prior to such Announced IPO Date. To the extent that the Announced IPO Date is subsequently advanced or delayed, the Corporation
shall send an amended IPO Notice of the revised proposed consummation date of the IPO to the Holders; provided, however, the Corporation
may not advance the Announced IPO Date to a date less than five (5) Business Days after the date of the latest amending IPO Notice.
If any Announced IPO Date is delayed, the amending IPO Notice will be deemed the establishment of a new Announced IPO Date and
any Conversion Notice given based on a previously Announced IPO Date will be deemed cancelled unless the Holder providing such
Conversion Notice affirms in writing the Conversion Notice as given.


 


9. Redemption Rights.


 


(a) No Optional Redemption.
The Corporation shall have no right to redeem the Series A Preferred Stock except as set forth in this Section 9.


 


(b) Mandatory Cash
Redemption. On the date that is the 21 month anniversary of the final Closing Date of the Offering, subject to extension upon
the prior written approval of the Required Holders (the “Mandatory Redemption Date”), the Corporation shall
repurchase all of the outstanding shares of Series A Preferred Stock at a redemption price for each Holder equal to the sum of:
(i) the product of (A) two, multiplied by (B) the aggregate Stated Value of all of the Series A Preferred Stock shares then held
by such Holder (as adjusted for any stock split, stock dividend, stock combination or other similar transactions with respect to
the Series A Preferred Stock), plus (ii) all accrued but unpaid dividends on such shares of Series A Preferred Stock to the date
of payment (the “Redemption Price”), in cash (“Mandatory Cash Redemption”).


 


(c) Redemption In-Kind.
Upon an Event of Default, and while the Event of Default is continuing, the Required Holders may elect in writing to cause the
Corporation (“Mandatory Redemption Notice”) to repurchase the Series A Preferred Stock through the Corporation’s
distribution of the assets of the Corporation having a value equal to the Redemption Price to the Holders or, upon the election
of the Required Holders, a trust or other entity established by the Required Holders for purposes of receiving the assets of the
Corporation (“Mandatory In-Kind Redemption”). Within ten days of the Corporation’s receipt of the Mandatory
Redemption Notice, the Corporation shall hire an independent nationally recognized valuation firm (“Valuation Firm”)
not unacceptable to the Required Holders for purposes of determining the fair market value of the Corporation’s assets (“Valuation”).
The Valuation Firm shall conduct the Valuation using such criteria and methodologies as are proposed by the Valuation Firm and
not unacceptable to the Corporation or the Required Holders. The Valuation shall assign fair market values to each significant
group of assets (each an “Asset Class”) of the Corporation. The Valuation Firm shall deliver the Valuation no
later than thirty (30) days of its engagement. In the event that the Valuation is less than the aggregate Redemption Price for
all Holders, the Corporation shall distribute to the Holders all of the assets of the Corporation within ten (10) days of the Valuation
Firm’s delivery of the Valuation. If the Valuation is greater than the aggregate Redemption Price for all Holders, the Corporation
shall distribute to the Holders a proportional amount of each Asset Class equal to the Valuation amount assigned to each Asset
Class by the Valuation Firm multiplied by a fraction the denominator of which is the Valuation and the numerator is the aggregate
Redemption Price for all Holders. Each Holder shall be entitled to receive its proportional share of distributed assets in each
Asset Class equal to the Valuation amount assigned to the distributed assets in each Asset Class multiplied by a fraction the denominator
of which is the aggregate Redemption Price for all Holders and the numerator is the Redemption Price for such Holder. From the
time of the Corporation’s receipt of the Mandatory Redemption Notice until the Corporation’s distribution of the assets
in accordance with this Section 9(c), the Corporation shall take no action to sell, transfer or diminish the assets of the Corporation
except (i) in the ordinary course of business or (ii) as approved in writing by the required Holders.


 




    41


     


    

 


(d) Mechanics of
Redemption. Upon receipt of payment of the Redemption Price by the Holders of Series A Preferred Stock in the event of a Mandatory
Cash Redemption or the Holders’ receipt of their proportional share of the assets of the Corporation in the event of a Mandatory
In-Kind Redemption, each Holder will deliver the certificate(s) evidencing the Series A Preferred Stock to be redeemed by the Corporation,
unless such Holder is awaiting receipt of a new certificate evidencing such shares from the Corporation pursuant to another provision
hereof.


 


(e) Insufficient
Legally Available Assets. If the assets of the Corporation legally available for redemption are insufficient to effect the
distributions contemplated by Section 9(c), those assets that are legally available shall be used to redeem the maximum possible
number of shares of Series A Preferred Stock pro rata among the Holders to be redeemed pursuant to Section 9(c) based upon the
Redemption Price held by each such Holder. At any time thereafter when additional assets of the Corporation are legally available
for the redemption of Series A Preferred Shares pursuant to Section 9(c), such assets shall immediately be used to redeem the balance
of the Series A Preferred Shares that the Corporation has become obligated to redeem pursuant to Section 9(c), but which it has
not redeemed.


 


10. Reservation of
Common Stock. The Corporation shall at all times reserve and keep available for issuance upon the conversion of shares of Series
A Preferred Stock, such number of its authorized but unissued shares of Common Stock as will from time to time be sufficient to
permit the conversion of all outstanding shares of Series A Preferred Stock, and shall take all action to increase the authorized
number of shares of Common Stock if at any time there shall be insufficient authorized but unissued shares of Common Stock to permit
such reservation or to permit the conversion of all outstanding shares of Series A Preferred Stock.


 


11. Charges, Taxes
and Expenses. The issuance of certificates for shares of Series A Preferred Stock and for Underlying Shares issued upon conversion
of (or otherwise in respect of) the Series A Preferred Stock shall be made without charge to the Holders for any issue or transfer
tax, withholding tax, transfer agent fee or other incidental tax or expense in respect of the issuance of such certificates, all
of which taxes and expenses shall be paid by the Corporation; provided, however, that the Corporation shall not be
required to pay any tax that may be payable in respect of any transfer involved in the registration of any certificates for Common
Stock or Series A Preferred Stock in a name other than that of the Holder of such certificates. The Holder shall be responsible
for all other tax liability that may arise as a result of holding or transferring the Series A Preferred Stock or receiving Underlying
Shares in respect of the Series A Preferred Stock.


 




    42


     


    

 


12. Replacement Certificates.
If any certificate evidencing Series A Preferred Stock or Underlying Shares is mutilated, lost, stolen or destroyed, the Corporation
shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof, or in lieu of and substitution
for such certificate, a new certificate, but only upon receipt of evidence reasonably satisfactory to the Corporation of such loss,
theft or destruction and customary and reasonable indemnity, if requested. Applicants for a new certificate under such circumstances
shall also comply with such other reasonable regulations and procedures and pay such other reasonable third-party costs as the
Corporation may prescribe.


 


13. Certain Adjustments.
The Conversion Price is subject to adjustment from time to time as set forth in this Section 13.


 


(a) Stock Dividends
and Splits. If the Corporation, at any time while any shares of Series A Preferred Stock are outstanding, (i) pays a stock
dividend on its Common Stock or otherwise makes a distribution on any class of capital stock that is payable in shares of Common
Stock, (ii) subdivides outstanding shares of Common Stock into a larger number of shares, or (iii) combines outstanding
shares of Common Stock into a smaller number of shares, then in each such case the Conversion Price shall be multiplied by a fraction
of which the numerator shall be the number of shares of Common Stock outstanding immediately before such event and of which the
denominator shall be the number of shares of Common Stock outstanding immediately after such event. Any adjustment made pursuant
to clause (i) of this paragraph shall become effective immediately following the close of business on the record date for the determination
of stockholders entitled to receive such dividend or distribution, and any adjustment pursuant to clause (ii) or (iii) of this
paragraph shall become effective immediately following the close of business on the effective date of such subdivision or combination.


 


(b) Fundamental Transactions.
If, at any time while any shares of Series A Preferred Stock are outstanding, (i) the Corporation effects any merger of the Corporation
into or consolidation of the Corporation with another Person, (ii) the Corporation effects any sale of all or substantially all
of its assets in one or a series of related transactions, or (iii) the Corporation effects any reclassification of the Common Stock
or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for other securities,
cash or property (other than as a result of a subdivision or combination of shares of Common Stock covered by Section 13(a) above)
(in any such case, a “Fundamental Transaction”), then upon any subsequent conversion of Series A Preferred Stock,
each Holder shall have the right to receive, for each Underlying Share that would have been issuable upon such conversion absent
such Fundamental Transaction, the same kind and amount of securities, cash or property as it would have been entitled to receive
upon the occurrence of such Fundamental Transaction if it had been, immediately prior to such Fundamental Transaction, the record
holder of such Underlying Shares immediately prior to such record date (the “Alternate Consideration”). For
purposes of any such conversion, the determination of the Conversion Price shall be appropriately adjusted to apply to such Alternate
Consideration based on the amount of Alternate Consideration issuable in respect of one share of Common Stock in such Fundamental
Transaction, and the Corporation shall apportion the Conversion Price among the Alternate Consideration in a manner reasonably
acceptable to the holders of a majority of the outstanding shares of Series A Preferred Stock reflecting the relative value of
any different components of the Alternate Consideration. If holders of Common Stock are given any choice as to the securities,
cash or property to be received in a Fundamental Transaction, then each Holder shall be given the same choice as to the Alternate
Consideration it receives upon any conversion of Series A Preferred Stock following such Fundamental Transaction. To the extent
necessary to effectuate the foregoing provisions, any successor to the Corporation or surviving entity in such Fundamental Transaction
shall issue to the Holders a new series of preferred stock consistent with the foregoing provisions and evidencing the Holders’
right to convert such preferred stock into Alternate Consideration. The terms of any agreement pursuant to which a Fundamental
Transaction is effected shall include terms requiring any such successor or surviving entity to comply with the provisions of this
Section 13 and insuring that the Series A Preferred Stock (or any such replacement security) will be similarly adjusted upon any
subsequent transaction analogous to a Fundamental Transaction.


 




    43


     


    

 


(c) Calculations.
All calculations under this Section 13 shall be made to the nearest cent or the nearest 1/100th of a share, as applicable. The
number of shares of Common Stock outstanding at any given time shall not include shares owned or held by or for the account of
the Corporation, and the disposition of any such shares shall be considered an issue or sale of Common Stock.


 


(d) Notice of Adjustments.
Upon the occurrence of each adjustment pursuant to this Section 13, the Corporation at its expense will promptly compute such adjustment
in accordance with the terms hereof and prepare a certificate describing in reasonable detail such adjustment and the transactions
giving rise thereto, including all facts upon which such adjustment is based. Upon written request, the Corporation will promptly
deliver a copy of each such certificate to each Holder.


 


(e) Notice of Corporate
Events. If the Corporation (i) declares a dividend or any other distribution of cash, securities or other property in respect
of its Junior Stock, including, without limitation, any granting of rights or warrants to subscribe for or purchase any capital
stock of the Corporation or any subsidiary, or (ii) authorizes or approves, enters into any agreement contemplating or solicits
stockholder approval for any Liquidation Event or Fundamental Transaction then the Corporation shall deliver to each Holder a notice
that shall specify (A) the record date for the purposes of such dividend, distribution of cash, securities or property or vote
of the stockholders of the Corporation, or if a record is not to be taken, the date as of which the holders of shares of Common
Stock of record to be entitled to such dividend, distribution of cash, securities or other property or vote of the stockholders
is to be determined, (B) the date on which such Liquidation Event or Fundamental Transaction is expected to become effective, and
(C) the material terms and conditions of such transaction, at least ten Business Days prior to the applicable record or effective
date on which a Person would need to hold Common Stock in order to participate in or vote with respect to such transaction, and
the Corporation will take all steps reasonably necessary in order to insure that each Holder is given the practical opportunity
to convert its Series A Preferred Stock prior to such time so as to participate in or vote with respect to such transaction; provided,
however, that the failure to deliver such notice or any defect therein shall not affect the validity of the corporate action required
to be described in such notice.


 


14. Fractional Shares.
The Corporation shall not be required to issue or cause to be issued fractional Underlying Shares upon conversion of Series A Preferred
Stock. If any fraction of an Underlying Share would, except for the provisions of this Section, be issuable upon conversion of
Series A Preferred Stock, the number of Underlying Shares to be issued will be rounded up to the nearest whole share.


 


15. Notices.
Any and all notices or other communications or deliveries hereunder (including without limitation any Conversion Notice) shall
be in writing and shall be deemed given and effective on the earliest of (i) the date of transmission, if such notice or communication
is delivered via facsimile at the facsimile number specified in this Section prior to 3:30 p.m. (Texas time) on a Business Day,
(ii) the next Business Day after the date of transmission, if such notice or communication is delivered via facsimile at the facsimile
number specified in this Section on a day that is not a Business Day or later than 3:30 p.m. (Texas time) on any Business Day,
(iii) the Business Day following the date of mailing, if sent by nationally recognized overnight courier service, or (iv) upon

to the address or facsimile number appearing on the Corporation’s stockholder records or such other address or facsimile
number as such Holder may provide to the Corporation in accordance with this Section 15.


 




    44


     


    

 


16. Dispute Resolution.
In the case of a dispute as to the determination of the fair value of consideration other than cash or securities, or the arithmetic
calculation of the Conversion Rate or the Redemption Price, the Corporation shall, as soon as practicable upon discovery, and following
a good faith effort to resolve the dispute with the Holder, submit (a) the disputed determination of the fair value of consideration
other than cash or securities to an independent, reputable investment bank selected by the Corporation or (b) the disputed
arithmetic calculation of the Conversion Rate or the Redemption Price to the Corporation’s independent, outside accountant.
The Corporation, at the Corporation’s expense, shall cause the investment bank or the accountant, as the case may be, to
perform the determinations or calculations and notify the Corporation and the Holder of the results no later than five (5) Business
Days from the time it receives the disputed determinations or calculations. Such investment bank’s or accountant’s
determination or calculation, as the case may be, shall be binding upon all parties absent demonstrable error.

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

any of the provisions hereof.


 


(b) No provision of

REGISTRATION RIGHTS AGREEMENT FOR
INVESTORS


 


THIS
REGISTRATION RIGHTS AGREEMENT (this “Agreement”) is made as of [●],
2018,1 by and
among TFF Pharmaceuticals, Inc., a Delaware corporation (“Company”), and the persons listed on Schedule
A hereto, referred to individually as the “Stockholder” and collectively as the “Stockholders”.


 


A.
In connection with the Securities Purchase Agreement by and among the parties hereto, dated as of [●],
2018 (the “Securities Purchase Agreement”), the Company has agreed, upon the terms and subject to the
conditions of the Securities Purchase Agreement, to issue and sell to each Investor Shares (as defined in the Securities Purchase
Agreement), which will be convertible into Conversion Shares (as defined in the Securities Purchase Agreement) in accordance with
the terms of the Series A Preferred Stock, par value $0.001 (the “Series A Preferred Stock”), set forth
in the Company’s Amended and Restated Certificate of Incorporation (the “Certificate”).


 


B. To induce the Stockholders
to consummate the transactions contemplated by the Securities Purchase Agreement, the Company has agreed to provide certain registration
rights under the Securities Act, and applicable state securities laws to the Stockholders, and their assignees or successors in
interest, certain rights to provide for the registration for resale of the Conversion Shares by means of a Registration Statement
under the Securities Act, pursuant to the terms of this Agreement. Such Conversion Shares acquired by the Stockholders and their
assignees or successors in interest, are referred to collectively as the “Registrable Securities”.


 


C. 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 Stockholder 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 and Exchange Act of 1934, as amended (the “1934 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 Stockholders 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 Stockholder hereunder to be included in the registration within ten (10) days after
the Company sends such notice to the Stockholders (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 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 Stockholder is subject to confidentiality obligations with respect to any
information gained in this process or any other material non-public information he, she or it obtains, (iv) each Stockholder or
assignee or successor in interest is subject to all applicable laws relating to insider trading or similar restrictions; and (v)
if all of the Registrable Securities of the Stockholders cannot be so included due to Commission Comments or Underwriter Cutbacks,
then the Company may reduce, in accordance with the provisions of Section 1(c) hereof, the number of securities covered by such
Registration Statement to the maximum number which would enable the Company to conduct such offering in accordance with the provisions
of Rule 415.


 





 






		1	The Agreement will be dated as of the Initial Closing Date.



 




    51


     


    

 


(b) Initial Registration
Statement. At the election of each Stockholder, the Company shall be required to include up to all Piggyback Shares held by
such Stockholder 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 Registrable Securities of the Stockholders cannot be so included due to Commission Comments or Underwriter Cutbacks,
then the Company may reduce, in accordance with the provisions of Section 1(c) hereof, the number of securities covered by the
Initial Registration Statement to the maximum number which would enable the Company to conduct such offering in accordance with
the provisions of Rule 415.


 


(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
or Underwriter Cutbacks, the Company and the Stockholders agree that securities shall be removed from such Registration Statement
in the following order until no further removal is required by Commission Comments 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;


 


(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 Stockholders 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 Stockholder in comparison to the number of Registrable Securities held by
all Stockholders who have requested to include any Registrable Securities in the Registration Statement.


 


(d) Mandatory Registrations.
In the event all of the Piggyback Shares of the Stockholders are not included in a Registration Statement due to Commission Comments
or Underwriter Cutbacks, the Company shall prepare and file an additional Registration Statement (the “Follow-up Registration
Statement”) with the Commission within sixty (60) days following the effectiveness of the previously filed Registration
Statement; provided, however, that the time period for filing the Follow-up Registration shall be extended to the extent
that the Commission publishes written Commission Guidance or the Company receives written Commission Guidance which provides for
a longer period before a Follow-up Registration Statement may be filed. The Follow-up Registration Statement shall cover the resale
of all of the Registrable Securities that were excluded from any previously filed Registration Statement. In the event that all
of the Piggyback Shares have not been registered in a Registration Statement after the Follow-up Registration Statement has been
declared effective, the Company shall use commercially reasonable efforts thereafter to register any remaining unregistered Registrable
Securities, subject to the provisions of Section 1(e) hereof.


 




    52


     


    

 


(e) 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 or Follow-up 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 and Follow-up 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 Stockholders, or (iii) such time as all of the Registrable Securities covered by such
Registration Statement may be sold by the Stockholders 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 Stockholder (“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).


 


(f) Termination of
Registration Rights. The registration rights afforded to the Stockholders under this Section 1 shall terminate on the earliest
date when all Registrable Securities of the Stockholder either: (i) have been publicly sold by the Stockholder 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 Stockholder 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
Stockholder.


 


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 Stockholders 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 Stockholders (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 Stockholders 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.


 






    53


     


    

 


(b) Inclusion of
Other Registrable Shares and Cutback Provisions. If as a result of Commission Comments, 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 Stockholders 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 Stockholders 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 Stockholders 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 Stockholder under this Section 2 shall terminate on the
earliest date when all Registrable Securities of the Stockholder either: (i) have been publicly sold by the Stockholder pursuant
to a Registration Statement, or (ii) may be sold by the Stockholder 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 until such time as all of such Registrable Securities shall have
been disposed of in accordance with the intended methods of disposition by the seller or sellers thereof as set forth in 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.


 






    54


     


    

 


(c) The Company shall
furnish to each Stockholder holding 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) 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.


 


(e) The Company shall
use its 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 Stockholders
holding 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 Stockholder 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 deliver ten (10) copies of such supplement or amendment to the Stockholder
(or such other number of copies as the Stockholder may reasonably request).


 






    55


     


    

 


(g) The Company shall
promptly notify the Stockholder 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 Stockholder by 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 Stockholder
is required under applicable securities laws to be described in a Registration Statement as an underwriter, at the reasonable request
of such Stockholder, the Company shall use its best efforts to furnish to such Stockholder, on the date of the effectiveness of
such Registration Statement and thereafter from time to time on such dates as the Stockholder 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 Stockholder, 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 Stockholder.


 


(i) If the Stockholder
is required under applicable securities laws to be described in a Registration Statement as an underwriter, then at the request
of such Stockholder in connection with such Stockholder’s due diligence requirements, the Company shall make available for
inspection by (i) the Stockholder, (ii) the Stockholder’s legal counsel, and (iii) one firm of accountants or other agents
retained by the Stockholder (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 Stockholder) 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 disclosure of such Records is necessary to avoid or correct a misstatement or omission in any Registration Statement or is
otherwise required under the Securities Act, (b) 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 (c) 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 Stockholder 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 Stockholder) shall be deemed to limit the
Stockholder’s ability to sell Registrable Securities in a manner which is otherwise consistent with applicable laws and regulations.


 


(j) The Company shall
hold in confidence and not make any disclosure of information concerning the Stockholder 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 Stockholder 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 Stockholder is sought in or by a court or
governmental body of competent jurisdiction or through other means, give prompt written notice to the Stockholder if permitted
by applicable law or regulation and allow the Stockholder, at the Stockholder’s expense, to undertake appropriate action
to prevent disclosure of, or to obtain a protective order for, such information.


 






    56


     


    

 


(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 Stockholder, the Company shall (i) as soon as practicable incorporate in a Prospectus supplement or post-effective amendment
such information as the Stockholder reasonably requests to be included therein relating to the sale and distribution of Registrable
Securities, including, without limitation, information with respect to the number of 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 Stockholder holding any Registrable
Securities.


 


(m) The Company shall
cooperate with each Stockholder 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 Stockholder may reasonably request and registered in such names as the Stockholder may request.


 


(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 in Section 3(d)
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 Stockholder 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).


 






    57


     


    

 


(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 Stockholder 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 Stockholder 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 Stockholder) and the date on which the Grace Period
will begin, and (ii) notify the Stockholder 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 Stockholder
receives the notice referred to in clause (i) and shall end on and include the later of the date the Stockholder 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 Stockholder in connection with any sale of Registrable Securities with respect to which the Stockholder
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 Stockholder’s receipt of the notice
of a Grace Period or, if earlier, Stockholders knowledge of the material, non-public information concerning the Company that gave
rise to the Grace Period, and for which the Stockholder has not yet settled.


 


4. Obligations of
the Stockholders.


 


(a) At least five (5)
business days prior to the first anticipated filing date of a Registration Statement, the Company shall notify the Stockholders
in writing of the information the Company requires from each Stockholder if the Stockholder’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 Stockholder that the Stockholder
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.


 






    58


     


    

 


(b) The Stockholder,
by the Stockholder’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 Stockholder has
notified the Company in writing of the Stockholder's election to exclude all of the Stockholder’s Registrable Securities
from such Registration Statement.


 


(c) The Stockholder
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 Stockholder will immediately discontinue disposition of Registrable Securities
pursuant to any Registration Statement(s) covering such Registrable Securities until the Stockholder’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 Stockholder in connection with any sale of Registrable Securities with respect to which
the Stockholder has entered into a contract for sale prior to the Stockholder’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, Stockholders 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 Stockholder has not yet settled.


 


(d) The Stockholder
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 (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.


 






    59


     


    

 


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 Stockholder, the directors, officers,
members, partners, employees, agents, representatives of, and each Person, if any, who controls the Stockholder 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 (“Blue Sky Filing”), 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 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 Stockholder 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 Stockholder pursuant to Section 10. “Related Information
Provider” means, in respect of any Indemnified Person, the Stockholder to which such Indemnified Person is related
or another Indemnified Person that is related to the Stockholder to which such Indemnified Person is related.


 


(b) To the fullest extent
permitted by law, in connection with any Registration Statement in which a Stockholder’s Registrable Securities are included
or in which a Stockholder is otherwise participating, such Stockholder 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 Stockholder or other Person selling securities
in such Registration Statement and any controlling person of any such underwriter or other Stockholder 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 in reliance upon and
in conformity with written information furnished by such Stockholder or by a Related Information Provider expressly for use in
connection with such Registration Statement; and each such Stockholder 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
Stockholder, which consent shall not be unreasonably withheld; provided, further, however, that the Stockholder
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 Stockholder as a result of the sale of Registrable Securities pursuant to such Registration Statement, except in the case
of fraud by such Stockholder. 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 Stockholder 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.


 






    61


     


    

 


(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 Stockholders 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
the maximum contribution with respect to any amounts for which it would otherwise be liable under Section 6 to the fullest extent
permitted by law; provided, however, that: (i) no Person involved in the sale of Registrable Securities which Person
is guilty of fraudulent misrepresentation (within the meaning of Section 10(f) of the Securities Act) in connection with such sale
shall be entitled to contribution from any Person involved in such sale of Registrable Securities who was not guilty of fraudulent
misrepresentation; and (ii) contribution by any seller of Registrable Securities shall be limited in amount to the net amount of
proceeds received by such seller from the sale of such Registrable Securities pursuant to such Registration Statement


 


8. No Delay of Registration.
No Stockholder shall have any right to obtain or seek an injunction restraining or otherwise delaying any registration as the result
of any controversy that might arise with respect to the interpretation or implementation of this Agreement.


 


9. Reports under
Securities Exchange Act. With a view to making available to the Stockholder the benefits of Rule 144 promulgated under the
Securities Act or any other similar rule or regulation of the Commission that may at any time permit the Stockholder to sell securities
of the Company to the public without registration, once the Company becomes a Reporting Company, the Company agrees to use its
commercially reasonable efforts to continue to be a Reporting Company for five years and further during such time it is a Reporting

assignment; (ii) the Company is, within a reasonable time after such transfer or assignment, furnished with written notice of (a)
the name and address of such transferee or assignee, and (b) the securities with respect to which such registration rights are

by the transferee or assignee is or might be restricted under the Securities Act and applicable state securities laws; and (iv)

[We are][I am] counsel

with that certain Registration Rights Agreement with _____________ (the “Stockholder”) (the “Registration Rights

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

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.

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 Stockholder Shares, unless we have otherwise informed you of the termination
of effectiveness of the registration statement in which the Stockholder 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

a transfer of Stockholder 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 Stockholder 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:


 


THE SECURITIES REPRESENTED BY
THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS. THE

SELLING STOCKHOLDERS


 


The shares of common stock being offered
by the selling stockholders are those issuable to the selling stockholders upon [conversion of the Series A Convertible Preferred
Stock and exercise of the warrants]. For additional information regarding the issuance of the [Series A Convertible Preferred Stock
and the warrants], see “Private Placement of Series A Convertible Preferred Stock” 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 Series A Convertible Preferred Stock 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 Series A Convertible Preferred Stock and the engagement of National Securities Corporation
as an underwriter for a public offering of common stock by the Company, and our engagement of an affiliate of National Securities
Corporation as a consultant in respect of our patents and intellectual property] 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 [, Series A Convertible Preferred Stock and warrants,] as of ________, 20__, [assuming conversion
of the Series A Convertible Preferred Stock 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 Series A Convertible Preferred Stock or (ii) exercise of the warrants set forth therein].


 


In accordance with the terms of a registration
rights agreement with the holders of the Series A Convertible Preferred Stock and the warrants, this prospectus generally covers
the resale of [(i) the shares of common stock issued upon conversion of the Series A Convertible Preferred Stock and (ii) the maximum
number of shares of common stock issuable upon exercise of the warrants, in each case, determined as if the outstanding Series
A Convertible Preferred Stock 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 Series A Convertible Preferred Stock 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.


 


See “Plan of Distribution.”

PLAN OF DISTRIBUTION


 


We are registering the shares of common
stock issued upon conversion of the Series A Convertible Preferred Stock to permit the resale of these shares of common stock by
the holders of Common Stock from time to time after the date of this prospectus. We will not receive any of the proceeds from the
sale by the selling stockholders of the shares of common stock. We will bear all fees and expenses incident to our obligation to
register the shares of common stock.


 


The selling stockholders 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.


 






    77


     


    

 


The selling stockholders may pledge or
grant a security interest in some or all of the [Series A Convertible Preferred Stock, 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.

ESCROW
AGREEMENT


 




    79


     


    

 


SUBSCRIPTION ESCROW AGREEMENT


 


This Subscription
Escrow Agreement (the “Escrow Agreement”), dated as of the effective date (the “Effective Date”) set forth
on Schedule 1 attached hereto (“Schedule 1”), by and among the corporation identified on Schedule 1 (the “Issuer”),
the corporation identified on Schedule 1 (the “Depositor”) and Delaware Trust Company, as escrow agent hereunder (the
“Escrow Agent”).


 


WHEREAS, the Issuer will offer to
certain accredited investors, pursuant to a Securities Purchase Agreement, as may be subsequently amended, the subscription and
sale of up to $14 million of shares of Series A Convertible Preferred Stock, $0.001 par value (the “Shares”), at a
price of $2.50 per Share; and


 


WHEREAS, the Depositor has been
named as the placement agent in connection with the proposed offering of the Shares.


 


NOW
THEREFORE, in consideration of the foregoing and of the mutual covenants hereinafter set forth, the parties hereto agree
as follows:


 


1. Appointment. The Issuer and Depositor
hereby appoint the Escrow Agent as their escrow agent for the purposes set forth herein, and the Escrow Agent hereby accepts such
appointment under the terms and conditions set forth herein.


 


2. Escrow Fund. All funds received
by the Depositor and the Issuer in connection with the sale of Shares shall be deposited with the Escrow Agent (the “Escrow
Deposit”). The Escrow Agent shall, subject to the terms and conditions hereof, hold the Escrow Deposit and any proceeds thereof
(the “Escrow Fund”) as directed in Section 3.


 


3. Investment of Escrow Fund.
During the term of this Escrow Agreement, the Escrow Fund shall be held in a non-interest bearing account by the Escrow Agent as
indicated on Schedule 1 or such other non-interest bearing investments as shall be directed in writing jointly by the Issuer and
the Depositor and as shall be acceptable to the Escrow Agent. The Escrow Agent may earn compensation in the form of short-term
interest (“float”) on items like uncashed distribution checks (from the date issued until the date cashed), funds that
it is directed not to invest, deposits awaiting investment direction or received too late to be invested overnight in previously
directed investments.


 


4. Disposition and Termination.
The Depositor and the Issuer agree to jointly notify the Escrow Agent in writing of the closing date of the offering (the “Offering
Closing Date”) and whether or not the Issuer received subscriptions that will result in the Issuer receiving gross proceeds
of at least $8,000,000 (the “Minimum Subscription Amount”). Upon receipt of such written notification the following
procedure will take place.


 


		(i)	If the Escrow Agent receives into the Escrow Fund subscriptions
for the Minimum Subscription Amount on or before June 30, 2018, subject to extension by the mutual written agreement of the Company
and Depositor to a date no later than December 31, 2018 (“Outside Date”) , the Escrow Fund will be promptly paid to
or credited to the accounts of, or otherwise transferred to, the Issuer and the Depositor pursuant to the joint-instructions from
the Issuer and the Depositor.



 






    80


     


    

 


		(ii)	If the Issuer does not receive into the Escrow Fund subscriptions
for the Minimum Subscription Amount by the Outside Date, or if any subscription is not accepted by the Issuer or the offering
is abandoned or terminated, the Escrow Agent shall be provided by Depositor with suitable notice and a list containing the amount
received from each subscriber whose funds have been deposited with the Escrow Agent (with respect to each subscriber the “Subscriber
Investment Amount”) and the name, address and Taxpayer Identification Number (“TIN”) of each subscriber. The
aggregate of all Subscriber Investment Amounts shall not exceed the amount of the Escrow Fund on the Offering Closing Date. The
Escrow Agent shall distribute to each subscriber the appropriate Subscriber Investment Amount without interest or deduction within
10 days of receipt of the information described in this Section 4(ii).



 


Upon delivery of the Escrow Fund to the
Issuer or the subscribers as the case may be, by the Escrow Agent, this Escrow Agreement shall terminate, subject to the provisions
of Section 8.


 


5. Escrow Agent. The Escrow Agent
undertakes to perform only such duties as are expressly set forth herein and no duties shall be implied. The Escrow Agent shall
have no liability under and no duty to inquire as to the provisions of any agreement other than this Escrow Agreement. The Escrow
Agent may rely upon and shall not be liable for acting or refraining from acting upon any written notice, instruction or request
furnished to it hereunder and believed by it to be genuine and to have been signed or presented by the proper party or parties.
The Escrow Agent shall be under no duty to inquire into or investigate the validity, accuracy or content of any such document.
The Escrow Agent shall have no duty to solicit any payments which may be due it or the Escrow Fund. The Escrow Agent shall not
be liable for any action taken or omitted by it in good faith except to the extent that a court of competent jurisdiction determines
that the Escrow Agent’s gross negligence or willful misconduct was the primary cause of any loss to the Issuer or Depositor. The
Escrow Agent may execute any of its powers and perform any of its duties hereunder directly or through agents or attorneys (and
shall be liable only for the careful selection of any such agent or attorney) and may consult with counsel, accountants and other
skilled persons to be selected and retained by it. The Escrow Agent shall not be liable for anything done, suffered or omitted
in good faith by it in accordance with the advice or opinion of any such counsel, accountants or other skilled persons. In the
event that the Escrow Agent shall be uncertain as to its duties or rights hereunder or shall receive instructions, claims or demands
from any party hereto which, in its opinion, conflict with any of the provisions of this Escrow Agreement, it shall be entitled
to refrain from taking any action and its sole obligation shall be to keep safely all property held in escrow until it shall be
directed otherwise in writing by all of the other parties hereto or by a final order or judgment of a court of competent jurisdiction.
Anything in this Escrow Agreement to the contrary notwithstanding, in no event shall the Escrow Agent be liable for special, indirect
or consequential loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Escrow Agent has
been advised of the likelihood of such loss or damage and regardless of the form of action.


 


6.Succession. The Escrow Agent may
resign and be discharged from its duties or obligations hereunder by giving 10 days advance notice in writing of such resignation
to the other parties hereto specifying a date when such resignation shall take effect. The Escrow Agent shall have the right to
withhold an amount equal to any amount due and owing to the Escrow Agent, plus any costs and expenses the Escrow Agent shall reasonably
believe may be incurred by the Escrow Agent in connection with the termination of the Escrow Agreement. Any corporation or association
into which the Escrow Agent may be merged or converted or with which it may be consolidated shall be the Escrow Agent under this
Escrow Agreement without further act.


 






    81


     


    

 


7. Fees. The Issuer agrees to (i)
pay the Escrow Agent upon execution of this Escrow Agreement and from time to time thereafter reasonable compensation for the services
to be rendered hereunder, which unless otherwise agreed in writing shall be as described in Schedule 1 attached hereto, and (ii)
pay or reimburse the Escrow Agent upon request for all expenses, disbursements and advances, including reasonable attorney’s fees
and expenses, incurred or made by it in connection with the preparation, execution, performance, delivery, modification and termination
of this Escrow Agreement. Provided the Minimum Subscription Amount is received and an Offering Closing Date is established, upon
such closing the Escrow Agent is authorized to deduct such fees from the Escrow Fund without prior authorization from the Issuer
or Depositor.


 


8. Indemnity. The Issuer and the
Depositor shall jointly and severally indemnify, defend and save harmless the Escrow Agent and its directors, officers, agents
and employees (the “indemnitees”) from all loss, liability or expense (including the fees and expenses of in house or
outside counsel) arising out of or in connection with (i) the Escrow Agent’s execution and performance of this Escrow Agreement,
except in the case of any indemnitee to the extent that such loss, liability or expense is due to the gross negligence or willful
misconduct of the Escrow Agent, or (ii) its following any instructions or other directions from the Issuer or the Depositor, except
to the extent that its following any such instruction or direction is expressly forbidden by the terms hereof. The parties hereto
acknowledge that the foregoing indemnities shall survive the resignation or removal of the Escrow Agent or the termination of this
Escrow Agreement. The parties hereby grant the Escrow Agent a lien on, right of set-off against and security interest in the Escrow
Fund for the payment of any claim for indemnification, compensation, expenses and amounts due hereunder.


 


9. TINs. The Issuer and the Depositor
represent that its correct Taxpayer Identification Number (“TIN”) assigned by the Internal Revenue Service or any other
taxing authority is set forth in Schedule 1. All interest or other income earned under the Escrow Agreement, if any, shall be allocated
to the Issuer and reported, to the extent required by law, by the Escrow Agent to the IRS or any other taxing authority, as applicable,
on IRS form 1099 or 1042S (or other appropriate form) as income earned from the Escrow Fund by the Issuer whether or not said income
has been distributed during the year.  Unless otherwise indicated in writing by the parties hereto, no taxes or other withholdings
are required to be made under applicable law or otherwise with respect to any payment to be made by Escrow Agent. All documentation
necessary to support a claim of exemption or reduction in such taxes or other withholdings has been timely collected by Issuer
and copies will be provided to Escrow Agent promptly upon a request therefor. Unless otherwise agreed to in writing by Escrow Agent,
all tax returns required to be filed with the IRS and any other taxing authority as required by law with respect to payments made
hereunder shall be timely filed and prepared by Issuer, including but not limited to, any applicable reporting or withholding pursuant
to the Foreign Account Tax Reporting Act (“FATCA”).  The parties hereto acknowledge and agree that the Escrow Agent
shall have no responsibility for the preparation and/or filing of any tax return or any applicable FATCA reporting with respect
to the Escrow Fund.  The Escrow Agent shall withhold any taxes it deems appropriate, including but not limited to required
withholding in the absence of proper tax documentation, and shall remit such taxes to the appropriate authorities as it determines
may be required by any law or regulation in effect at the time of the distribution.


 


10. Notices. All communications
hereunder shall be in writing and shall be deemed to be duly given and received:


 


(i) upon delivery if delivered
personally or upon confirmed transmittal if by facsimile or by other electronic means;


 


(ii) on the next Business Day
(as hereinafter defined) if sent by overnight courier; or


 


(iii) four (4) Business Days after
mailing if mailed by prepaid registered mail, return receipt requested, to the appropriate notice address set forth on Schedule
1 or at such other address as any party hereto may have furnished to the other parties in writing by registered mail, return receipt
requested.


 






    82


     


    

 


Notwithstanding the above, in the case
of communications delivered to the Escrow Agent pursuant to (ii) and (iii) of this Section 10, such communications shall be deemed
to have been given on the date received by the Escrow Agent. In the event that the Escrow Agent, in its sole discretion, shall
determine that an emergency exists, the Escrow Agent may use such other means of communication as the Escrow Agent deems appropriate.
“Business Day” shall mean any day other than a Saturday, Sunday or any other day on which the Escrow Agent located at
the notice address set forth on Schedule 1 is authorized or required by law or executive order to remain closed.


 


11. Security Procedures. In the
event Escrow Fund transfer instructions are given (other than in writing at the time of execution of this Escrow Agreement), whether
in writing, by telecopier or otherwise, the Escrow Agent is authorized to seek confirmation of such instructions by telephone call-back
to the person or persons designated on schedule 2 hereto (“Schedule 2”), and the Escrow Agent may rely upon the confirmation
of anyone purporting to be the person or persons so designated. The persons and telephone numbers for call-backs may be changed
only in a writing actually received and acknowledged by the Escrow Agent. The Escrow Agent and the beneficiary’s bank in any funds
transfer may rely solely upon any account numbers or similar identifying numbers provided by the Issuer or the Depositor to identify
(i) the beneficiary, (ii) the beneficiary’s bank, or (iii) an intermediary bank. The Escrow Agent may apply any of the escrowed
funds for any payment order it executes using any such identifying number, even where its use may result in a person other than
the beneficiary being paid, or the transfer of funds to a bank other than the beneficiary’s bank or an intermediary bank designated.
The parties to this Escrow Agreement acknowledge that these security procedures are commercially reasonable.


 


12. Miscellaneous. The provisions
of this Escrow Agreement may be waived, altered, amended or supplemented, in whole or in part, only by a writing signed by all
of the parties hereto. Neither this Escrow Agreement nor any right or interest hereunder may be assigned in whole or in part by
any party, except as provided in Section 6, without the prior consent of the other parties. This Escrow Agreement shall be governed
by and construed under the laws of the State of Delaware. Each party hereto irrevocably waives any objection on the grounds of
venue, forum non-conveniens or any similar grounds and irrevocably consents to service of process by mail or in any other manner
permitted by applicable law and consents to the jurisdiction of the courts located in the State of Delaware. The parties further
hereby waive any right to a trial by jury with respect to any lawsuit or judicial proceeding arising or relating to this Escrow
Agreement. No party to this Escrow Agreement is liable to any other party for losses due to, or if it is unable to perform its
obligations under the terms of this Escrow Agreement because of, acts of God, fire, floods, strikes, equipment or transmission
failure, or other causes reasonably beyond its control. This Escrow Agreement may be executed in one or more counterparts, each
of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

of Section 162(m) of the Code. The Committee, if established, will act by majority approval of the members (unanimous approval

consistent with applicable corporate law of the Company’s jurisdiction of incorporation, the Committee may delegate to any
officers of the Company the duties, power and authority of the Committee under the Plan (other than those that must be exercised
by the Committee to satisfy the requirements of Section 162(m) of the Code) pursuant to such conditions or limitations as the Committee
may establish; provided, however, that only the Committee may exercise such duties, power and authority with respect to Eligible
Recipients who are subject to Section 16 of the Exchange Act. The Committee may exercise its duties, power and authority under
the Plan in its sole and absolute discretion without the consent of any Participant or other party, unless the Plan specifically
provides otherwise. Each determination, interpretation or other action made or taken by the Committee pursuant to the provisions
of the Plan will be conclusive and binding for all purposes and on all persons, and no member of the Committee will be liable for
any action or determination made in good faith with respect to the Plan or any Incentive Award granted under the Plan.


 






    91


     


    

 


3.2. Authority of the Committee.


 


(a) In accordance with and subject
to the provisions of the Plan, the Committee will have the authority to determine all provisions of Incentive Awards as the Committee
may deem necessary or desirable and as consistent with the terms of the Plan, including, without limitation, the following: (i)
the Eligible Recipients to be selected as Participants; (ii) the nature and extent of the Incentive Awards to be made to each Participant
(including the number of shares of Common Stock to be subject to each Incentive Award, any exercise price, the manner in which
Incentive Awards will vest or become exercisable and whether Incentive Awards will be granted in tandem with other Incentive Awards)
and the form of written agreement, if any, evidencing such Incentive Award; (iii) any Performance Criteria applicable to any Incentive
Awards; (iv) the time or times when Incentive Awards will be granted and, where applicable, settled; (v) the duration of each Incentive
Award; (vi) the restrictions and other conditions to which the payment or vesting of Incentive Awards may be subject. In addition,
the Committee will have the authority under the Plan in its sole discretion to pay the economic value of any Incentive Award in
the form of cash, Common Stock or any combination of both.


 


(b) Subject to Section 3.2(d),
below, the Committee will have the authority under the Plan to amend or modify the terms of any outstanding Incentive Award in
any manner, including, without limitation, the authority to modify the number of shares or other terms and conditions of an Incentive
Award, extend the term of an Incentive Award, accelerate the exercisability or vesting or otherwise terminate any restrictions
relating to an Incentive Award other than an Incentive Award intended to qualify as “performance-based” compensation
within the meaning of Section 162(m) of the Code, accept the surrender of any outstanding Incentive Award or, to the extent not
previously exercised or vested, authorize the grant of new Incentive Awards in substitution for surrendered Incentive Awards; provided,
however that the amended or modified terms are permitted by the Plan as then in effect and that any Participant adversely affected
by such amended or modified terms has consented to such amendment or modification. Notwithstanding the foregoing, no Performance
Award (or any other Incentive Award) that is subject to the requirements and restrictions of Section 409A of the Code may be amended
in a manner that would violate Section 409A of the Code.


 


(c) In the event of (i) any reorganization,
merger, consolidation, recapitalization, liquidation, reclassification, stock dividend, stock split, combination of shares, rights
offering, extraordinary dividend or divestiture (including a spin-off) or any other change in corporate structure or shares; (ii)
any purchase, acquisition, sale, disposition or write-down of a significant amount of assets or a significant business; (iii) any
change in accounting principles or practices, tax laws or other such laws or provisions affecting reported results; or (iv) any
other similar change, in each case with respect to the Company or any other entity whose performance is relevant to the grant or
vesting of an Incentive Award, the Committee (or, if the Company is not the surviving corporation in any such transaction, the
board of directors of the surviving corporation) may, without the consent of any affected Participant, amend or modify the vesting
criteria (including Performance Criteria) of any outstanding Incentive Award that is based in whole or in part on the financial
performance of the Company (or any Subsidiary or division or other subunit thereof) or such other entity so as equitably to reflect
such event, with the desired result that the criteria for evaluating such financial performance of the Company or such other entity
will be substantially the same (in the sole discretion of the Committee or the board of directors of the surviving corporation)
following such event as prior to such event; provided, however, that the amended or modified terms are permitted by the Plan as
then in effect.


 


(d) Notwithstanding any other
provision of this Plan other than Section 4.3, the Committee may not, without prior approval of the Company’s stockholders,
seek to effect any re-pricing of any previously granted, “underwater” Option by: (i) amending or modifying the terms
of the Option to lower the exercise price; (ii) canceling the underwater Option and granting either (A) replacement Options
having a lower exercise price; (B) Restricted Stock Awards; or (C) Performance Awards in exchange; or (iii) repurchasing
the underwater Options and granting new Incentive Awards under this Plan. For purposes of this Section 3.2(d) and Section 11.4,
an Option will be deemed to be “underwater” at any time when the Fair Market Value of the Common Stock is less than
the exercise price of the Option.


 






    92


     


    

 


3.3 Annual Award Limitation.
The total number of Restricted Stock Awards, Restricted Stock Units and other shares of Common Stock subject to or underlying Options
or Performance Awards awarded to any Participant during any year may not exceed 250,000 shares. A Performance Award, as measured
on the date of grant, paid to a Participant with respect to any Performance Period may not exceed $500,000 times the number of
years in the Performance Period.


 


4. Shares Available for Issuance.


 


4.1. Maximum Number of Shares
Available; Certain Restrictions on Awards. Subject to adjustment as provided in Section 4.3 of the Plan, the maximum number
of shares of Common Stock that will be available for issuance under the Plan will be 1,630,000, and the maximum number of shares
of Common Stock that will be available for issuance in connection with Incentive Stock Options is 1,630,000. The shares available
for issuance under the Plan may, at the election of the Committee, be either treasury shares or shares authorized but unissued,
and, if treasury shares are used, all references in the Plan to the issuance of shares will, for corporate law purposes, be deemed
to mean the transfer of shares from treasury.


 


4.2. Accounting for Incentive
Awards. Shares of Common Stock that are issued under the Plan or that are subject to outstanding Incentive Awards will be applied
to reduce the maximum number of shares of Common Stock remaining available for issuance under the Plan; provided, however, that
shares subject to an Incentive Award that lapses, expires, is forfeited (including issued shares forfeited under a Restricted Stock
Award) or for any reason is terminated unexercised or unvested or is settled or paid in cash or any form other than shares of Common
Stock will automatically again become available for issuance under the Plan. To the extent that the exercise price of any Option
and/or associated tax withholding obligations are paid by tender or attestation as to ownership of Previously Acquired Shares,
or to the extent that such tax withholding obligations are satisfied by withholding of shares otherwise issuable upon exercise
of the Option, only the number of shares of Common Stock issued net of the number of shares tendered, attested to or withheld will
be applied to reduce the maximum number of shares of Common Stock remaining available for issuance under the Plan.


 


4.3. Adjustments to Shares
and Incentive Awards. In the event of any reorganization, merger, consolidation, recapitalization, liquidation, reclassification,
stock dividend, stock split, combination of shares or any other change in the corporate structure or shares of the Company, the
Committee (or, if the Company is not the surviving corporation in any such transaction, the board of directors of the surviving
corporation) will make appropriate adjustment (which determination will be conclusive) as to the number and kind of securities
or other property (including cash) available for issuance or payment under the Plan and, in order to prevent dilution or enlargement
of the rights of Participants, the number and kind of securities or other property (including cash) subject to outstanding Incentive
Awards and the exercise price of outstanding Options.


 


5. Participation.


 


Participants in the
Plan will be those Eligible Recipients who, in the judgment of the Committee, have contributed, are contributing or are expected
to contribute to the achievement of economic objectives of the Company or its Subsidiaries. Eligible Recipients may be granted
from time to time one or more Incentive Awards, singly or in combination or in tandem with other Incentive Awards, as may be determined
by the Committee in its sole discretion. Incentive Awards will be deemed to be granted as of the date specified in the grant resolution
of the Committee, which date will be the date of any related agreement with the Participant.


 






    93


     


    

 


6. Options.


 


6.1. Grant. An Eligible
Recipient may be granted one or more Options under the Plan, and such Options will be subject to such terms and conditions, consistent
with the other provisions of the Plan, as may be determined by the Committee in its sole discretion. The Committee may designate
whether an Option is to be considered an Incentive Stock Option or a Non-Statutory Stock Option. To the extent that any Incentive
Stock Option granted under the Plan ceases for any reason to qualify as an “incentive stock option” for purposes of
Section 422 of the Code, such Incentive Stock Option will continue to be outstanding for purposes of the Plan but will thereafter
be deemed to be a Non-Statutory Stock Option.


 


6.2. Exercise Price. The
per share price to be paid by a Participant upon exercise of an Option will be determined by the Committee in its discretion at
the time of the Option grant; provided, however, that such price will not be less than 100% of the Fair Market Value of one share
of Common Stock on the date of grant with respect to any Incentive Stock Option (110% of the Fair Market Value with respect to
an Incentive Stock Option if, at the time such Incentive Stock Option is granted, the Participant owns, directly or indirectly,
more than 10% of the total combined voting power of all classes of stock of the Company or any parent or subsidiary corporation
of the Company).


 


6.3. Exercisability and Duration.
An Option will become exercisable at such times and in such installments and upon such terms and conditions as may be determined
by the Committee in its sole discretion at the time of grant (including without limitation (i) the achievement of one or more of
the Performance Criteria and/or (ii) that the Participant remain in the continuous employ or service of the Company or a Subsidiary
for a certain period); provided, however, that if the Committee does not specify the expiration date of the Option, the expiration
date shall be 10 years from the date on which the Option was granted. In no case may an Option may be exercisable after 10 years
from its date of grant (five years from its date of grant in the case of an Incentive Stock Option if, at the time the Incentive
Stock Option is granted, the Participant owns, directly or indirectly, more than 10% of the total combined voting power of all
classes of stock of the Company or any parent or subsidiary corporation of the Company).


 


6.4. Payment of Exercise Price.
The total purchase price of the shares to be purchased upon exercise of an Option will be paid entirely in cash (including check,
bank draft or money order); provided, however, that the Committee, in its sole discretion and upon terms and conditions established
by the Committee, may allow such payments to be made, in whole or in part, by tender of a Broker Exercise Notice, by tender, or
attestation as to ownership, of Previously Acquired Shares that have been held for the period of time necessary to avoid a charge
to the Company’s earnings for financial reporting purposes and that are otherwise acceptable to the Committee, or by a combination
of such methods. For purposes of such payment, Previously Acquired Shares tendered or covered by an attestation will be valued
at their Fair Market Value on the exercise date.


 


6.5. Manner of Exercise.
An Option may be exercised by a Participant in whole or in part from time to time, subject to the conditions contained in the Plan
and in the agreement evidencing such Option, by delivery in person, by facsimile or electronic transmission or through the mail
of written notice of exercise to the Company at its legal department and by paying in full the total exercise price for the shares
of Common Stock to be purchased in accordance with Section 6.4 of the Plan.


 


7. Restricted Stock Awards and Restricted
Stock Units.


 


7.1. Grant. An Eligible
Recipient may be granted one or more Restricted Stock Awards or Restricted Stock Units under the Plan, and such Restricted Stock
Awards and Restricted Stock Units will be subject to such terms and conditions, consistent with the other provisions of the Plan,
as may be determined by the Committee in its sole discretion. The Committee may impose such restrictions or conditions, not inconsistent
with the provisions of the Plan, to the vesting of such Restricted Stock Awards and Restricted Stock Units as it deems appropriate,
including, without limitation, (i) the achievement of one or more of the Performance Criteria and/or (ii) that the Participant
remain in the continuous employ or service of the Company or a Subsidiary for a certain period.


 






    94


     


    

 


7.2. Rights as a Stockholder;
Transferability. Except as provided in Sections 7.1, 7.3, 7.4 and 12.3 of the Plan, a Participant will have all voting, dividend,
liquidation and other rights with respect to shares of Common Stock issued to the Participant as a Restricted Stock Award or pursuant
to a Restricted Stock Unit under this Section 7 upon the Participant becoming the holder of record of such shares as if such Participant
were a holder of record of shares of unrestricted Common Stock.


 


7.3. Dividends and Distributions.
Unless the Committee determines otherwise in its sole discretion (either in the agreement evidencing the Restricted Stock Award
at the time of grant or at any time after the grant of the Restricted Stock Award), any dividends or distributions (other than
regular quarterly cash dividends) paid with respect to shares of Common Stock subject to the unvested portion of a Restricted Stock
Award will be subject to the same restrictions as the shares to which such dividends or distributions relate. The Committee will
determine in its sole discretion whether any interest will be paid on such dividends or distributions. A Participant to whom Restricted
Stock Units have been granted will have no rights to receive any dividends or distributions with respect to the shares of Common
Stock underlying the Restricted Stock Units unless and until the Restricted Stock Units is settled and the Participant becomes
the holder of record of any shares of Common Stock delivered in settlement of such Restricted Stock Units.


 


7.4. Enforcement of Restrictions.
To enforce the restrictions referred to in this Section 7, the Committee may place a legend on the stock certificates referring
to such restrictions and may require the Participant, until the restrictions have lapsed, to keep the stock certificates, together
with duly endorsed stock powers, in the custody of the Company or its transfer agent, or to maintain evidence of stock ownership,
together with duly endorsed stock powers, in a certificateless book-entry stock account with the Company’s transfer agent.

8.1. Grant. An Eligible
Recipient may be granted one or more Performance Awards under the Plan, and such Performance Awards will be subject to such terms
and conditions, if any, consistent with the other provisions of the Plan, as may be determined by the Committee in its sole discretion.

is at or above the minimum level, but falls short of full achievement of the specified Performance Criteria. The grant of Performance

that the Performance Criteria have been satisfied.


 


8.4. Settlement – Time

time.


 


(c) To the extent the agreement
does not provide for the settlement of vested Performance Awards on or before the date that is 2-1/2 months after the end of the
year in which the Performance Award (or the relevant portion thereof) vests, the agreement will provide for payment to occur: (a)
upon the Eligible Recipient’s separation from service, death or disability; (b) upon a change in control of the Company;
or (c) upon a specified date or pursuant to a specified schedule. In all cases in which payment is to be made in accordance with

or distributions with respect to the Shares subject to a Performance Award unless and until the Performance Award is settled and

termination of employment or service, and Restricted Stock Awards, Restricted Stock Units and Performance Awards then held by such
Participant may vest and/or continue to vest or become free of restrictions and conditions to issuance, as the case may be, following
such termination of employment or service, in each case in the manner determined by the Committee.


 


9.5. Effects of Actions Constituting

acting in its sole discretion, to have committed any action which would constitute Cause as defined in Section 2.3, irrespective

or other service will, for purposes of the Plan, be deemed to have terminated on the date recorded on the personnel or other records
of the Company or the Subsidiary for which the Participant provides employment or service, as determined by the Committee in its
sole discretion based upon such records.


 


10. Payment of Withholding Taxes.


 


10.1. General Rules. The
Company is entitled to (a) withhold and deduct from future wages of the Participant (or from other amounts that may be due and
owing to the Participant from the Company or a Subsidiary), or make other arrangements for the collection of, all legally required
amounts necessary to satisfy any and all federal, foreign, state and local withholding and employment-related tax requirements
attributable to an Incentive Award, including, without limitation, the grant, exercise or vesting of, or payment of dividends with
respect to, an Incentive Award or a disqualifying disposition of stock received upon exercise of an Incentive Stock Option, or
(b) require the Participant promptly to remit the amount of such withholding to the Company before taking any action, including
issuing any shares of Common Stock, with respect to an Incentive Award.

10.2. Special Rules. The
Committee may, in its sole discretion and upon terms and conditions established by the Committee, permit or require a Participant
to satisfy, in whole or in part, any withholding or employment-related tax obligation described in Section 10.1 of the Plan by
electing to tender, or by attestation as to ownership of, Previously Acquired Shares that have been held for the period of time
necessary to avoid a charge to the Company’s earnings for financial reporting purposes and that are otherwise acceptable
to the Committee, by delivery of a Broker Exercise Notice or a combination of such methods. For purposes of satisfying a Participant’s
withholding or employment-related tax obligation, Previously Acquired Shares tendered or covered by an attestation will be valued
at their Fair Market Value.


 


11. Change in Control.


 


11.1. A “Change in Control”
shall be deemed to have occurred if the event set forth in any one of the following paragraphs has occurred:


 


(a) the sale, lease, exchange
or other transfer, directly or indirectly, of substantially all of the assets of the Company (in one transaction or in a series
of related transactions) to any Successor;


 


(b) the approval by the stockholders
of the Company of any plan or proposal for the liquidation or dissolution of the Company;


 


(c) any Successor (as defined
in Section 11.2 below), other than a Bona Fide Underwriter (as defined in Section 11.2 below), becomes after the effective date
of the Plan the “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of (i)
25% or more, but not 50% or more, of the combined voting power of the Company’s outstanding securities ordinarily having
the right to vote at elections of directors, unless the transaction resulting in such ownership has been approved in advance by
the Continuity Directors (as defined in Section 11.2 below), or (ii) more than 50% of the combined voting power of the Company’s
outstanding securities ordinarily having the right to vote at elections of directors (regardless of any approval by the Continuity
Directors);


 


(d) a merger or consolidation
to which the Company is a party if the stockholders of the Company immediately prior to effective date of such merger or consolidation
have “beneficial ownership” (as defined in Rule 13d-3 under the Exchange Act), immediately following the effective
date of such merger or consolidation, of securities of the surviving corporation representing (i) 50% or more, but not more than
80%, of the combined voting power of the surviving corporation’s then outstanding securities ordinarily having the right
to vote at elections of directors, unless such merger or consolidation has been approved in advance by the Continuity Directors,
or (ii) less than 50% of the combined voting power of the surviving corporation’s then outstanding securities ordinarily
having the right to vote at elections of directors (regardless of any approval by the Continuity Directors); or


 


(e) the Continuity Directors cease
for any reason to constitute at least 50% or more of the Board.


 


11.2. Change in Control Definitions.
For purposes of this Section 11:


 


(a) “Continuity Directors”
of the Company will mean any individuals who are members of the Board on the effective date of the Plan and any individual who
subsequently becomes a member of the Board whose election, or nomination for election by the Company’s stockholders, was
approved by a vote of at least a majority of the Continuity Directors (either by specific vote or by approval of the Company’s
proxy statement in which such individual is named as a nominee for director without objection to such nomination).


 






    98


     


    

 


(b) “Bona Fide Underwriter”
means an entity engaged in business as an underwriter of securities that acquires securities of the Company through such entity’s
participation in good faith in a firm commitment underwriting until the expiration of 40 days after the date of such acquisition.


 


(c) “Successor”
means any individual, corporation, partnership, group, association or other “person,” as such term is used in Section
13(d) or Section 14(d) of the Exchange Act, other than the Company, any “affiliate” (as defined below) or any benefit
plan(s) sponsored by the Company or any affiliate that succeeds to, or has the practical ability to control (either immediately
or solely with the passage of time), the Company’s business directly, by merger, consolidation or other form of business
combination, or indirectly, by purchase of the Company’s outstanding securities ordinarily having the right to vote at the
election of directors or all or substantially all of its assets or otherwise. For this purpose, an “affiliate” is (i)
any corporation at least a majority of whose outstanding securities ordinarily having the right to vote at elections of directors
is owned directly or indirectly by the Company; (ii) any other form of business entity in which the Company, by virtue of a direct
or indirect ownership interest, has the right to elect a majority of the members of such entity’s governing body or (iii)
any entity that at the time of the approval of this Plan owns in excess of 10% of the Company’s common stock and its affiliates.


 


11.3. Acceleration of Vesting.
Without limiting the authority of the Committee under Sections 3.2 and 4.3 of the Plan, if a Change in Control of the Company occurs,
then, if approved by the Committee in its sole discretion either in an agreement evidencing an Incentive Award at the time of grant
or at any time after the grant of an Incentive Award: (a) all Options that have been outstanding for at least six months will become
immediately exercisable in full and will remain exercisable in accordance with their terms; and (b) all Restricted Stock Awards
and Restricted Stock Units that have been outstanding for at least six months will become immediately fully vested and non-forfeitable;
and (c) any conditions to the issuance of cash or shares of Common Stock pursuant to Performance Awards that have been outstanding
for at least six months will lapse.


 


11.4. Cash Payment. If
a Change in Control of the Company occurs, then the Committee, if approved by the Committee in its sole discretion either in an
agreement evidencing an Incentive Award at the time of grant or at any time after the grant of an Incentive Award, and without
the consent of any Participant affected thereby, may determine that:


 


(a) Some or all Participants holding
outstanding Options will receive, with respect to some or all of the shares of Common Stock subject to such Options (“Option
Shares”), either (i) as of the effective date of any such Change in Control, cash in an amount equal to the excess of the
Fair Market Value of such Option Shares on the last business day prior to the effective date of such Change in Control over the
exercise price per share of such Option Shares, (ii) immediately prior to such Change of Control, a number of shares of Common
Stock having an aggregate Fair Market Value equal to the excess of the Fair Market Value of the Option Shares as of the last business
day prior to the effective date of such Change in Control over the exercise price per share of such Option Shares; or (iii) any
combination of cash or shares of Common Stock with the amount of each component to be determined by the Committee not inconsistent
with the foregoing clauses (i) and (ii), as proportionally adjusted; and


 


(b) any Options which, as of the
effective date of any such Change in Control, are “underwater” (as defined in Section 3.2(d)) shall terminate as of
the effective date of any such Change in Control; and


 


(c) some or all Participants holding
Performance Awards will receive, with respect to some or all of the shares of Common Stock subject to such Performance Awards that
remain subject to issuance based upon the future achievement of Performance Criteria or other future event as of the effective
date of any such Change in Control of the Company, cash in an amount equal the Fair Market Value of such shares immediately prior
to the effective date of such Change in Control.


 






    99


     


    

 


11.5. Limitation on Change
in Control Payments. Notwithstanding anything in Section 11.3 or 11.4 of the Plan to the contrary, if, with respect to
a Participant, the acceleration of the exercisability of an Option as provided in Section 11.3 or the payment of cash or shares
of Common Stock in exchange for all or part of an Option as provided in Section 11.4 (which acceleration or payment could be deemed
a “payment” within the meaning of Section 280G(b)(2) of the Code), together with any other “payments”
that such Participant has the right to receive from the Company or any corporation that is a member of an “affiliated group”
(as defined in Section 1504(a) of the Code without regard to Section 1504(b) of the Code) of which the Company is a member,
would constitute a “parachute payment” (as defined in Section 280G(b)(2) of the Code), then the “payments”
to such Participant pursuant to Section 11.3 or 11.4 of the Plan will be reduced to the largest amount as will result in no portion
of such “payments” being subject to the excise tax imposed by Section 4999 of the Code; provided, however, that if
a Participant is subject to a separate agreement with the Company or a Subsidiary which specifically provides that payments attributable
to one or more forms of employee stock incentives or to payments made in lieu of employee stock incentives will not reduce any
other payments under such agreement, even if it would constitute an excess parachute payment, or provides that the Participant
will have the discretion to determine which payments will be reduced in order to avoid an excess parachute payment, then the limitations
of this Section 11.4 will, to that extent, not apply.


 


12. Rights of Eligible Recipients and
Participants; Transferability.


 


12.1. Employment or Service.
Nothing in the Plan will interfere with or limit in any way the right of the Company or any Subsidiary to terminate the employment
or service of any Eligible Recipient or Participant at any time, nor confer upon any Eligible Recipient or Participant any right
to continue in the employ or service of the Company or any Subsidiary.


 


12.2. Rights as a Stockholder.
As a holder of Incentive Awards (other than Restricted Stock Awards), a Participant will have no rights as a stockholder unless
and until such Incentive Awards are exercised for, or paid in the form of, shares of Common Stock and the Participant becomes the
holder of record of such shares. Except as otherwise provided in the Plan, no adjustment will be made for dividends or distributions
with respect to such Incentive Awards as to which there is a record date preceding the date the Participant becomes the holder
of record of such shares, except as the Committee may determine in its discretion.


 


12.3. Restrictions on Transfer.


 


(a) Except pursuant to testamentary
will or the laws of descent and distribution or as otherwise expressly permitted by subsections (b) and (c) below, no right or
interest of any Participant in an Incentive Award prior to the exercise (in the case of Options) or vesting (in the case of Restricted
Stock Awards) or settlement (in the case of Restricted Stock Units or Performance Awards) of such Incentive Award will be assignable
or transferable, or subjected to any lien, during the lifetime of the Participant, either voluntarily or involuntarily, directly
or indirectly, by operation of law or otherwise.


 


(b) A Participant will be entitled
to designate a beneficiary to receive an Incentive Award upon such Participant’s death, and in the event of such Participant’s
death, payment of any amounts due under the Plan will be made to, and exercise of any Options (to the extent permitted pursuant
to Section 9 of the Plan) may be made by, such beneficiary. If a deceased Participant has failed to designate a beneficiary, or
if a beneficiary designated by the Participant fails to survive the Participant, payment of any amounts due under the Plan will
be made to, and exercise of any Options (to the extent permitted pursuant to Section 9 of the Plan) may be made by, the Participant’s
legal representatives, heirs and legatees. If a deceased Participant has designated a beneficiary and such beneficiary survives
the Participant but dies before complete payment of all amounts due under the Plan or exercise of all exercisable Options, then
such payments will be made to, and the exercise of such Options may be made by, the legal representatives, heirs and legatees of
the beneficiary.

(c) Upon a Participant’s
request, the Committee may, in its sole discretion, permit a transfer of all or a portion of a Non-Statutory Stock Option, other
than for value, to such Participant’s child, stepchild, grandchild, parent, stepparent, grandparent, spouse, former spouse,
sibling, niece, nephew, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law, or sister-in-law, any person
sharing such Participant’s household (other than a tenant or employee), a trust in which any of the foregoing have more than
fifty percent of the beneficial interests, a foundation in which any of the foregoing (or the Participant) control the management
of assets, and any other entity in which these persons (or the Participant) own more than fifty percent of the voting interests.
Any permitted transferee will remain subject to all the terms and conditions applicable to the Participant prior to the transfer.
A permitted transfer may be conditioned upon such requirements as the Committee may, in its sole discretion, determine, including,
but not limited to execution and/or delivery of appropriate acknowledgements, opinion of counsel, or other documents by the transferee.


 


12.4. Non-Exclusivity of the
Plan. Nothing contained in the Plan is intended to modify or rescind any previously approved compensation plans or programs
of the Company or create any limitations on the power or authority of the Board to adopt such additional or other compensation
arrangements as the Board may deem necessary or desirable.


 


13. Securities Law and Other Restrictions.


 


Notwithstanding any
other provision of the Plan or any agreements entered into pursuant to the Plan, the Company will not be required to issue any
shares of Common Stock under this Plan, and a Participant may not sell, assign, transfer or otherwise dispose of shares of Common
Stock issued pursuant to Incentive Awards granted under the Plan, unless (a) there is in effect with respect to such shares a registration
statement under the Securities Act and any applicable securities laws of a state or foreign jurisdiction or an exemption from such
registration under the Securities Act and applicable state or foreign securities laws, and (b) there has been obtained any other
consent, approval or permit from any other U.S. or foreign regulatory body which the Committee, in its sole discretion, deems necessary
or advisable. The Company may condition such issuance, sale or transfer upon the receipt of any representations or agreements from
the parties involved, and the placement of any legends on certificates representing shares of Common Stock, as may be deemed necessary
or advisable by the Company in order to comply with such securities law or other restrictions.


 


14. Plan Amendment, Modification and
Termination.


 


The Board may suspend
or terminate the Plan or any portion thereof at any time, and may amend the Plan from time to time in such respects as the Board
may deem advisable in order that Incentive Awards under the Plan will conform to any change in applicable laws or regulations or
in any other respect the Board may deem to be in the best interests of the Company; provided, however, that no such amendments
to the Plan will be effective without approval of the Company’s stockholders if: (i) stockholder approval of the amendment
is then required pursuant to Section 422 of the Code or the rules of any stock exchange or the NASDAQ Global Select, Global or
Capital Market or similar regulatory body; or (ii) such amendment seeks to modify Section 3.2(d) hereof. No termination, suspension
or amendment of the Plan may adversely affect any outstanding Incentive Award without the consent of the affected Participant;
provided, however, that this sentence will not impair the right of the Committee to take whatever action it deems appropriate under
Sections 3.2(c), 4.3 and 11 of the Plan.


 


15. Effective Date and Duration of the
Plan.


 


The Plan is effective
as of the Effective Date. The Plan will terminate at midnight on January 24, 2028 and may be terminated prior to such time by Board
action. No Incentive Award will be granted after termination of the Plan. Incentive Awards outstanding upon termination of the
Plan may continue to be exercised, or become free of restrictions, according to their terms.

16. Miscellaneous.


 


16.1. Governing Law. Except
to the extent expressly provided herein or in connection with other matters of corporate governance and authority (all of which
shall be governed by the laws of the Company’s jurisdiction of incorporation), the validity, construction, interpretation,
administration and effect of the Plan and any rules, regulations and actions relating to the Plan will be governed by and construed
exclusively in accordance with the laws of the State of Delaware notwithstanding the conflicts of laws principles of any jurisdictions.
