and other documents filed or furnished, as applicable, by the Company under the Exchange Act, including pursuant to Section 13(a)

their respective filing dates, the Company SEC Documents complied in all material respects with the requirements of the Securities
Act and the Exchange Act and the rules and regulations of the Securities and Exchange Commission (the “SEC”)
promulgated thereunder, and none of the Company SEC Documents, when filed, contained any untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary to make the statements therein in light of the circumstances
under which they were made not misleading. The consolidated financial statements contained in the Company SEC Documents: (i) complied
in all material respects with applicable accounting requirements and the published rules and regulations of the SEC applicable
thereto; (ii) were prepared in accordance with generally accepted accounting principles applied on a consistent basis throughout
the periods covered, except as may be indicated in the notes to such financial statements and (in the case of unaudited statements)
as permitted by Form 10-Q of the SEC, and except that unaudited financial statements may not contain footnotes and are subject
to year-end audit adjustments; and (iii) fairly present the consolidated financial position of the Company and its subsidiaries
as of the respective dates thereof and the consolidated results of operations cash flows and the changes in stockholders’
equity of the Company and its subsidiaries for the periods covered thereby. There is no transaction, arrangement, or other relationship
between the Company (or any of its subsidiaries) and an unconsolidated or other off balance sheet entity that is required to be
disclosed by the Company in its Exchange Act filings and is not so disclosed. Except as
set forth in the Company SEC Documents filed prior to the date hereof, subsequent to January

or entered into any material transactions, or declared or paid any dividends or made any distribution of any kind with respect
to its capital stock; and there has not been any change in the capital stock (other than a change in the number of outstanding
shares of Common Stock due to the issuance of equity compensation awards under the Company’s equity compensation plans or
shares upon the exercise of outstanding options or warrants or upon the conversion of outstanding shares of convertible preferred
stock), or any material change in the short-term or long-term debt, or any issuance of options, warrants, convertible securities
or other rights to purchase the capital stock, of the Company (other than issuances of equity compensation awards under the Company’s
equity compensation plans) or any of its subsidiaries, or any material adverse change in the condition (financial or otherwise),
business, prospects, management, properties, operations or results of operations of the Company and its subsidiaries, taken as
a whole (“Material Adverse Change”) or any development which could reasonably be expected to result in any Material
Adverse Change.


2.6


Capitalization. The
authorized capital stock of the Company consists of (i) 750,000,000 shares of Common Stock, of which (A) 29,765,702
shares were issued and 28,506,774 shares were outstanding as of the date of this Agreement, and (B) 7,140,717 shares were
reserved for issuance upon the exercise or conversion, as the case may be, of outstanding options, warrants or other
convertible securities (other than the Company’s convertible preferred stock discussed below) as of the date of this
Agreement; and (ii) 50,000,000 shares of preferred stock, 5,000,000 of which have been designated Series A Preferred Stock
(the “Series A Stock”), 2,000,000 of which have been designated Series B Preferred Stock (the
“Series B Stock”), 17,000,000 of which have been designated Series B1 Preferred Stock (the
“Series B1 Stock”) and 44,000 of which have been designated as Series C Convertible Preferred Stock (the

outstanding, (2) 8,407,492 shares of Series B Stock are issued and outstanding, (3) no shares of Series B1 Stock are issued
and outstanding, (4) 44,000 shares of Series C Convertible Preferred Stock are issued and outstanding, and (5) no shares of
Series A Stock, Series B Stock, Series B1 Stock, or Series C Stock are reserved for issuance upon the exercise or conversion,
as the case may be, of outstanding options, warrants or other convertible securities. All
of the issued and outstanding shares of capital stock of the Company, including the outstanding shares of Common Stock,
Series A Stock, Series B Stock and Series C Stock, are duly authorized and validly issued, fully paid and nonassessable, have
been issued in compliance with all federal and state and foreign securities laws, were not issued in violation of or subject
to any preemptive rights or other rights to subscribe for or purchase securities that have not been waived in writing, and
the holders thereof are not subject to personal liability by reason of being such holders. The Securities are duly
authorized and, when issued, sold and delivered and paid for in accordance with the terms of this Agreement, the Preferred
Stock or the Warrants, as the case may be, will be duly and validly authorized and issued, fully paid and nonassessable, free
from all taxes, liens, claims, encumbrances and charges with respect to the issue thereof and the holders thereof will not be
subject to personal liability to the Company or its stockholders by reason of being such holders; provided, however, that the
Securities may be subject to restrictions on transfer under state and/or federal securities laws or as otherwise set forth
herein. The issuance, sale and delivery of the Units and the Underlying Shares in accordance with the terms of this
Agreement, the Preferred Stock or the Warrant, as the case may be, will not be subject to preemptive rights of stockholders
of the Company. The Conversion Shares have been duly reserved for issuance pursuant to the terms set forth in the certificate
of designation of the Preferred Stock (the “Certificate of Designation”), in the form attached hereto as Exhibit
C. The Warrant Shares have been duly reserved for issuance upon exercise of the Warrants.
All of the issued and outstanding shares of capital stock of the Company’s subsidiaries have been duly and validly
authorized and issued and are fully paid and nonassessable, and, except as otherwise described in the Company SEC Documents,
the Company owns of record and beneficially, free and clear of any security interests, claims, liens, proxies, equities or
other encumbrances, all of the issued and outstanding shares of such stock. Except as described in the Company SEC Documents,
there are no options, warrants, agreements, contracts or other rights in existence to purchase or acquire from the Company or
any subsidiaries of the Company any shares of the capital stock of the Company or any subsidiaries of the Company (other than
issuances of equity compensation awards under the Company’s equity compensation plans). The description of the
Company’s stock option, stock bonus and other stock plans or arrangements, and the options or other rights granted
thereunder, set forth in the Company SEC Documents accurately and fairly presents the information required to be shown with
respect to such plans, arrangements, options and rights. There are no anti-dilution or price adjustment provisions,
co-sale rights, registration rights, rights of first refusal or other similar rights contained in the terms governing any
outstanding security of the Company that will be triggered by the issuance of the Securities, except as disclosed in the
SEC Documents.

the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015, the Company, directly or indirectly,
owns no capital stock or other equity or ownership or proprietary interest in any corporation, partnership, association, trust
or other entity.


2.8


Offering. Assuming
the accuracy of the representations of the Purchasers in Section 3.3 of this Agreement, on the Closing Date and solely as this
Section 2.8 relates to the issue and sale of (i) the Warrant Shares on the date(s) of exercise of the Warrant, and (ii) the Conversion
Shares on the date(s) of conversion of the Preferred Stock, the offer, issue and sale of the Units and issuance of the Warrant

requirements of the Securities Act and have been or will be registered or qualified (or are or will be exempt from registration
and qualification) under the registration, permit or qualification requirements of all applicable state securities laws. Neither
the Company, nor any of its affiliates, nor any person acting on its or their 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 under
the Securities Act of the issuance of the Units to the Purchasers, the issuance of the Warrant Shares upon exercise of the Warrants
or the issuance of the Conversion Shares upon the conversion of Preferred Stock. Other than the Company SEC Documents, the Company
has not distributed and will not distribute prior to the Closing Date any offering material in connection with the offering and
sale of the Units or Underlying Shares. The Company has not taken any action to sell, offer for sale or solicit offers to buy any
securities of the Company which would bring the offer, issuance or sale of the Units, the issuance of the Warrant Shares upon exercise

of the Securities Act, unless such offer, issuance or sale was or shall be within the exemptions of Section 4 of the Securities
Act. The issuance and sale of the Securities hereunder does not contravene the rules and regulations of the Principal Market.

employment with the Company nor any of its subsidiaries or actions undertaken by the employee while employed with the Company or

2.13


No Violations or
Defaults.  Neither the Company nor any of its subsidiaries is in violation of its respective
charter, by-laws or other organizational documents, or in breach of or otherwise in default, and no event has occurred which,
with notice or lapse of time or both, would constitute such a default in the performance of any material obligation, agreement
or condition contained in any bond, debenture, note, indenture, loan agreement or any other material contract, lease or other instrument
to which it is subject or by which any of them may be bound, or to which any of the material property or assets of the Company

with respect thereto, other than any which the Company or its subsidiaries is contesting in good faith. There is no pending dispute
with any taxing authority relating to any of such returns, and the Company has no knowledge of any liability for any tax to be
imposed upon the properties or assets of the Company for which there is not an adequate reserve reflected in the Company’s
financial statements included in the Company SEC Documents.

included or approved for listing on the Nasdaq Capital Market (the “Principal Market”) and
the Company has taken no action designed to, or likely to have the effect of, terminating the registration of the Common Stock
under the Exchange Act or delisting the Common Stock from the Principal Market nor has the Company received any notification that
the Commission or the Principal Market is contemplating terminating such registration or listing. The Company has complied in all
material respects with the applicable requirements of the Principal Market for maintenance of inclusion of the Common Stock thereon.



2.16


Internal
Controls. The Company and its subsidiaries maintain a system of internal accounting controls designed to provide reasonable
assurances that (i) transactions are executed in accordance with management’s general or specific authorization; (ii) transactions
are recorded as necessary to permit preparation of financial statements in conformity with generally accepted accounting principles
in the United States and to maintain accountability for assets; (iii) access to assets is permitted only in accordance with
management’s general or specific authorization; and (iv) the recorded accountability for assets is compared with existing
assets at reasonable intervals and appropriate action is taken with respect to any differences. Except as disclosed in the Company
SEC Documents, the Company’s internal control over financial reporting is effective and none of the Company, its board of
directors and audit committee is aware of any “significant deficiencies” or “material weaknesses” (each
as defined by the Public Company Accounting Oversight Board) in its internal control over financial reporting, or any fraud, whether
or not material, that involves management or other employees of the Company and its subsidiaries who have a significant role in
the Company’s internal controls; and since the end of the latest audited fiscal year, and except as otherwise disclosed in
the SEC Documents, there has been no change in the Company’s internal control over financial reporting (whether or not remediated)
that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial
reporting. The Company’s board of directors has, subject to the exceptions, cure periods and the phase in periods specified
in the applicable stock exchange rules (“Exchange Rules”), validly appointed an audit committee to oversee internal
accounting controls whose composition satisfies the applicable requirements of the Exchange Rules and the Company’s board
of directors and/or the audit committee has adopted a charter that satisfies the requirements of the Exchange Rules.

or other fee or commission in connection with the transactions contemplated by this Agreement based on arrangements made by the
Company.


2.18

Company carries, or is covered by, insurance from insurers with appropriately rated claims paying abilities in such amounts and
covering such risks as is adequate for the conduct of its business and the value of its properties and as is customary for companies

by the Company or any of its subsidiaries under any such policy or instrument as to which any insurance company is denying liability
or defending under a reservation of rights clause; neither the Company nor any of its subsidiaries have been refused any insurance
coverage sought or applied for; and neither the Company nor any of its subsidiaries has reason to believe that it will not be able
to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers
as may be necessary to continue its business at a cost that would not have a Material Adverse Effect.

claim would individually or in the aggregate, have a Material Adverse Effect; and the Company is not aware of any pending investigation
which might lead to such a claim. Neither the Company nor any of its subsidiaries anticipates incurring any material capital expenditures
relating to compliance with Environmental Laws.


2.26


Compliance with
Occupational Laws. The Company and its subsidiaries (A) are in compliance, in
all material respects, with any and all applicable foreign, federal, state and local laws, rules, regulations, treaties, statutes
and codes promulgated by any and all Governmental Authorities (including pursuant to the Occupational Health and Safety Act) relating
to the protection of human health and safety in the workplace (“Occupational Laws”); (B) have received all material
permits, licenses or other approvals required of it under applicable Occupational Laws to conduct its business as currently conducted;
and (C) are in compliance, in all material respects, with all terms and conditions of such permit, license or approval. No action,
proceeding, revocation proceeding, writ, injunction or claim is pending or, to the Company’s knowledge, threatened against
the Company or any of its subsidiaries relating to Occupational Laws, and the Company does not have knowledge of any facts, circumstances
or developments relating to its operations or cost accounting practices that could reasonably be expected to form the basis for
or give rise to such actions, suits, investigations or proceedings.


2.27


ERISA and Employee
Benefits Matters. (i) To the knowledge of the Company, no “prohibited transaction” as defined under Section 406
of ERISA or Section 4975 of the Code and not exempt under ERISA Section 408 and the regulations and published interpretations thereunder
has occurred with respect to any Employee Benefit Plan. At no time has the Company or any ERISA Affiliate maintained, sponsored,
participated in, contributed to or has or had any liability or obligation in respect of any Employee Benefit Plan subject to Part
3 of Subtitle B of Title I of ERISA, Title IV of ERISA, or Section 412 of the Code or any “multiemployer plan” as defined
in Section 3(37) of ERISA or any multiple employer plan for which the Company or any ERISA Affiliate has incurred or could incur
liability under Section 4063 or 4064 of ERISA. No Employee Benefit Plan provides or promises, or at any time provided or promised,
retiree health, life insurance, or other retiree welfare benefits except as may be required by the Consolidated Omnibus Budget
Reconciliation Act of 1985, as amended, or similar state law. Each Employee Benefit Plan is and has been operated in material compliance
with its terms and all applicable laws, including but not limited to ERISA and the Code and, to the knowledge of the Company, no
event has occurred (including a “reportable event” as such term is defined in Section 4043 of ERISA) and no condition
exists that would subject the Company or any ERISA Affiliate to any material tax, fine, lien, penalty or liability imposed by ERISA,
the Code or other applicable law. Each Employee Benefit Plan intended to be qualified under Code Section 401(a) is so qualified
and has a favorable determination or opinion letter from the IRS upon which it can rely, and any such determination or opinion
letter remains in effect and has not been revoked; to the knowledge of the Company, nothing has occurred since the date of any
such determination or opinion letter that is reasonably likely to adversely affect such qualification; (ii) with respect to each
Foreign Benefit Plan, such Foreign Benefit Plan (A) if intended to qualify for special tax treatment, meets, in all material respects,
the requirements for such treatment, and (B) if required to be funded, is funded to the extent required by applicable law, and
with respect to all other Foreign Benefit Plans, adequate reserves therefore have been established on the accounting statements
of the applicable Company or its subsidiaries; (iii) the Company does not have any obligations under any collective bargaining
agreement with any union and no organization efforts are underway with respect to Company employees. As used in this Agreement,
“Code” means the Internal Revenue Code of 1986, as amended; “Employee Benefit Plan” means
any “employee benefit plan” within the meaning of Section 3(3) of ERISA, including, without limitation, all stock purchase,
stock option, stock-based severance, employment, change-in-control, medical, disability, fringe benefit, bonus, incentive, deferred
compensation, employee loan and all other employee benefit plans, agreements, programs, policies or other arrangements, whether
or not subject to ERISA, under which (A) any current or former employee, director or independent contractor of the Company or any
of its subsidiaries has any present or future right to benefits and which are contributed to, sponsored by or maintained by the
Company or any of its subsidiaries or (B) the Company or any of its subsidiaries has had or has any present or future obligation
or liability; “ERISA” means the Employee Retirement Income Security Act of 1974, as amended; “ERISA
Affiliate” means any member of the company’s controlled group as defined in Code Section 414(b), (c), (m) or (o);
and “Foreign Benefit Plan” means any Employee Benefit Plan established, maintained or contributed to outside
of the United States of America or which covers any employee working or residing outside of the United States.

2.28


Labor Matters.
No labor problem or dispute with the employees of the Company or any of its subsidiaries exists or is threatened or imminent, and
the Company is not aware of any existing or imminent labor disturbance by the employees of any of its or its subsidiaries’
principal suppliers, contractors or customers, that could have a Material Adverse Effect.


2.29


Statistical Information.
Any third-party statistical and market-related data included in the Company SEC Documents are based on or derived from sources
that the Company believes to be reliable and accurate in all material respects.


2.30


Forward-looking
Statements.


2.31


Transfer Taxes.
On the Closing Date, all stock transfer or other taxes (other than income taxes) that are required to be paid in connection with
the sale and transfer of the Securities hereunder will be, or will have been, fully paid or provided for by the Company and the
Company will have complied with all laws imposing such taxes.


2.32


No General Solicitation.
Neither the Company, nor any of its affiliates, nor any person acting on its or their behalf, has engaged in any form of general
solicitation or general advertising (within the meaning of Regulation D promulgated under the Securities Act) in connection with
the offer or sale of the Securities.


2.33


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, business combination, poison pill (including any distribution under a rights
agreement) or other similar anti-takeover provision under the Company’s charter or the laws of the jurisdiction of its formation
which is or could become applicable to any Purchaser as a result of the transactions contemplated by this Agreement, including,
without limitation, the Company’s issuance of the Securities and any Purchaser’s ownership of the Securities. The Company
has not adopted a stockholder rights plan or similar arrangement relating to accumulations of beneficial ownership of Common Stock
or a change in control of the Company.

2.34


No Manipulation;
Disclosure of Information. The Company has not taken and will not take any action designed to or that might reasonably be expected
to cause or result in an unlawful manipulation of the price of the Common Stock or the Preferred Stock to facilitate the sale or
resale of the Units. The Company confirms that, with the exception of the proposed sale of the Securities as contemplated herein,
neither it nor any other person acting on its behalf has provided any of the Purchasers or their agents or counsel with any information
that constitutes or might constitute material, non-public information. The Company understands and confirms that the Purchasers
shall be relying on the foregoing representations in effecting transactions in securities of the Company. All disclosures provided
to the Purchasers regarding the Company, its business and the transactions contemplated hereby furnished by the Company are true
and correct and do not contain any untrue statement of a material fact or omit to state any material fact necessary in order to
make the statements made therein, in light of the circumstances under which they were made, not misleading.


2.35


Certain Acknowledgements.
Anything in this Agreement or elsewhere herein to the contrary notwithstanding (except for Sections 3.7 and 6.11 hereof), it is
understood and acknowledged by the Company that: (i) none of the Purchasers has been asked by the Company to agree, nor has any
Purchaser agreed, to desist from purchasing or selling, long and/or short, securities of the Company, or “derivative”
securities based on securities issued by the Company or to hold the Securities for any specified term; (ii) past or future open
market or other transactions by any Purchaser, specifically including, without limitation, Short Sales (as defined below) or “derivative”
transactions, before or after the closing of this or future private placement transactions, may negatively impact the market price
of the Company’s publicly-traded securities; (iii) any Purchaser, and counter-parties in “derivative” transactions
to which any such Purchaser is a party, directly or indirectly, presently may have a “short” position in the Common
Stock, and (iv) each Purchaser shall not be deemed to have any affiliation with or control over any arm’s length counter-party
in any “derivative” transaction. The Company further understands and acknowledges that (y) one or more Purchasers
may engage in hedging activities at various times during the period that the Securities are outstanding, and (z) such hedging
activities (if any) could reduce the value of the existing stockholders’ equity interests in the Company at and after the
time that the hedging activities are being conducted. The Company acknowledges that such aforementioned hedging activities do
not constitute a breach hereof.


2.36


No Additional Agreements.
Other than with respect to closing mechanics, the Company has no other agreements or understandings (including, without limitation,
side letters) with any Purchaser or other person to purchase Securities on terms more favorable to such person than as set forth
herein.


2.37


No “Bad Actor”
Disqualification. The Company has exercised reasonable care, in accordance with SEC rules and guidance, and has conducted a
factual inquiry, the nature and scope of which reflect reasonable care under the relevant facts and circumstances, to determine
whether any Covered Person (as defined below) is subject to any of the “bad actor” disqualifications described in Rule
506(d)(1)(i) to (viii) under the Securities Act (“Disqualification Events”). To the Company’s knowledge,
after conducting such sufficiently diligent factual inquiries, no Covered Person is subject to a Disqualification Event, except
for a Disqualification Event covered by Rule 506(d)(2) or (d)(3) under the Securities Act. The Company has complied, to the extent
applicable, with any disclosure obligations under Rule 506(e) under the Securities Act. “Covered Persons” are
those persons specified in Rule 506(d)(1) under the Securities Act, including the Company; any predecessor or affiliate of the
Company; any director, executive officer, other officer participating in the offering, general partner or managing member of the
Company; any beneficial owner of 20% or more of the Company’s outstanding voting equity securities, calculated on the basis
of voting power; any promoter (as defined in Rule 405 under the Securities Act) connected with the Company in any capacity at the
time of the sale of the Units; and any person that has been or will be paid (directly or indirectly) remuneration for solicitation
of purchasers in connection with the sale of the Units (a “Solicitor”), any general partner or managing member
of any Solicitor, and any director, executive officer or other officer participating in the offering of any Solicitor or general
partner or managing member of any Solicitor.

3.


Representations and Warranties of the
Purchasers. Each Purchaser, severally and not jointly, hereby represents and warrants to the Company as follows:


3.1


Legal Power. 
If the Purchaser is a corporation, limited partnership, or limited liability company, such Purchaser is validly existing and has
all requisite corporate, partnership, or limited liability company power and authority to invest in the Units pursuant to this
Agreement. The Purchaser has the requisite authority to enter into this Agreement and to carry out and perform its obligations
under the terms of this Agreement. All action on the Purchaser’s part required for the lawful execution and delivery of this
Agreement have been or will be effectively taken prior to the Closing.


3.2


Due Execution. This
Agreement has been duly authorized, executed and delivered by the Purchaser, and, upon due execution and delivery by the Company,
this Agreement will be a valid and binding agreement of the Purchaser, except as rights to indemnity hereunder may be limited by
federal or state securities laws and except as such enforceability may be limited by bankruptcy, insolvency, reorganization or
similar laws affecting the rights of creditors generally and subject to general principles of equity.


3.3


Investment Representations.
In connection with the sale and issuance of the Securities, the Purchaser, for itself and no other Purchaser, makes the following
representations:


(a)


Investment for Own
Account. The Purchaser is acquiring the Securities for its own account, not as nominee or agent, and not with a view to, or
for resale in connection with, any distribution or public offering thereof within the meaning of the Securities Act, and such Purchaser
has no present intention of selling, granting any participation in, or otherwise distributing the same in violation of the Securities
Act; provided, however, that by making the representations herein, the Purchaser does not agree to hold any of the Units for any
minimum or 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 from the registration requirements of the Securities Act.


(b)


Transfer Restrictions;
Legends. The Purchaser understands that (i) the Securities have not been registered under the Securities Act; (ii) the Securities
are being offered and sold pursuant to an exemption from registration, based in part upon the Company’s reliance upon
the statements and representations made by the Purchasers in this Agreement, and that the Securities may be held by the
Purchaser indefinitely, and that the Purchaser may, therefore, bear the economic risk of such investment indefinitely, unless a
subsequent disposition thereof is registered under the Securities Act or is exempt from such registration; (iii) each Certificate
representing any of the Preferred Stock, the Warrants and the Underlying Shares will be endorsed with the following legend until
the earlier of (1) in the case of any of the Preferred Stock, the Warrants and the Underlying Shares, such date as the Preferred
Stock, Warrants or Underlying Shares, as the case may be, have been registered for resale by the Purchaser or (2) the date any
of the Preferred Stock, the Warrants or the Underlying Shares, as the case may be, are eligible for sale under Rule 144 under the
Securities Act:


THE SECURITIES REPRESENTED HEREBY
HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR UNDER THE SECURITIES
LAWS OF ANY STATES. THESE SECURITIES ARE SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AND RESALE AND MAY NOT BE TRANSFERRED OR RESOLD
EXCEPT AS PERMITTED UNDER THE SECURITIES ACT AND THE APPLICABLE STATE SECURITIES LAWS, PURSUANT TO REGISTRATION OR EXEMPTION THEREFROM.
UNLESS SOLD PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, THE ISSUER OF THESE SECURITIES MAY REQUIRE
AN OPINION OF COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER TO THE EFFECT THAT ANY PROPOSED TRANSFER OR RESALE IS IN
COMPLIANCE WITH THE SECURITIES ACT AND ANY APPLICABLE STATE SECURITIES LAWS.






    	 		Page 11



    	 



    

 


(iv) the Company will instruct any transfer
agent not to register the transfer of the Preferred Stock, Warrants or Underlying Shares (or any portion thereof) until the applicable
date set forth in clause (iii) above unless (A) the conditions specified in the foregoing legends are satisfied, (B) if the opinion
of counsel referred to above is to the further effect that such legend is not required in order to establish compliance with any
provisions of the Securities Act or this Agreement, (C) or (D) other satisfactory assurances of such nature are given to the Company.


The Company acknowledges
and agrees that a Purchaser may from time to time pledge, and/or grant a security interest in some or all of the Securities pursuant
to a bona fide margin agreement in connection with a bona fide margin account and, if required under the terms of such agreement
or account, the Purchaser may transfer pledged or secured Securities to the pledgees or secured parties. Such a pledge or transfer
shall not be subject to approval or consent of the Company and no legal opinion of legal counsel to the pledgee, secured party
or pledgor shall be required in connection with the pledge, but such legal opinion may be required in connection with a subsequent
transfer following default by the Purchaser transferee of the pledge. No notice shall be required of such pledge. At the appropriate
Purchaser’s expense, the Company will execute and deliver such reasonable documentation as a pledgee or secured party of
Securities may reasonably request in connection with a pledge or transfer of the Securities including the preparation and filing
of any required prospectus supplement under Rule 424(b)(3) of the Securities Act or other applicable provision of the Securities
Act to appropriately amend the list of Selling Stockholders thereunder.


Certificates
evidencing the Securities shall not contain any legend (including the legend set forth in this Section): (i) upon the effectiveness
of a registration statement (including the Registration Statement) covering the Securities (provided that the Purchaser agrees
to only sell such Securities during such time that such registration statement is effective and not withdrawn or suspended, and
only as permitted by such registration statement), or (ii) following a sale of such Securities pursuant to Rule 144, or (iii) while
such Securities are eligible for sale under Rule 144, if such Securities have been held for one year or more pursuant to the requirements
of Rule 144, or (iv) if such legend is not required under applicable requirements of the Securities Act (including judicial interpretations
and pronouncements issued by the Staff of the SEC). Following such time as restrictive legends are not required to be placed on
certificates representing Securities, the Company will, no later than three business days following the delivery by a Purchaser
to the Company or the Company’s transfer agent of a certificate representing Securities containing a restrictive legend and
such other documentation and representations as the Company, its legal counsel or Transfer Agent may reasonably request to confirm
compliance with the preceding sentence as applicable (provided, however, that neither the Company nor its legal counsel will require
a legal opinion in connection with any sale pursuant to Rule 144), deliver or cause to be delivered to such Purchaser a certificate
representing such Securities that is free from all restrictive and other legends. The Company shall cause its counsel to issue
a legal opinion to the Company’s transfer agent promptly after the effective date of a registration statement covering the
Securities if required by the Company’s transfer agent to effect the removal of the legend hereunder. The Company may not
make any notation on its records or give instructions to any transfer agent of the Company that enlarge the restrictions on transfer
set forth in this Section. Certificates for Securities subject to legend removal hereunder shall be transmitted by the transfer
agent of the Company to the Purchasers by crediting the account of the Purchaser’s prime broker with the Depository Trust
Company system. The Company will pay all fees and expenses of its transfer agent and the Depository Trust Company in connection
with the removal of legends pursuant to this Section 3.3(b).






    	 		Page 12



    	 



    

 


Each Purchaser,
severally and not jointly with the other Purchasers, agrees that the removal of the restrictive legend from certificates representing
Securities as set forth in this Section 3.3(b) is predicated upon the Company’s reliance that the Purchaser will sell
any Securities pursuant to either the registration requirements of the Securities Act, including any applicable prospectus delivery
requirements, or an exemption therefrom.


(c)


Financial Sophistication;
Due Diligence. The Purchaser has such knowledge and experience in financial or business matters that it is capable of evaluating
the merits and risks of the investment in connection with the transactions contemplated in this Agreement. Such Purchaser has,
in connection with its decision to purchase the Units, relied only upon the representations and warranties contained herein and
the information contained in the Company SEC Documents. Further, the Purchaser has
had such opportunity to obtain additional information and to ask questions of, and receive answers from, the Company, concerning
the terms and conditions of the investment and the business and affairs of the Company, as the Purchaser considers necessary in
order to form an investment decision. Such Purchaser acknowledges access to the Company
SEC Documents.


(d)


Accredited Investor Status. The Purchaser
is an “accredited investor” as such term is defined in Rule 501(a) of the rules and regulations promulgated under the
Securities Act.


(e)


Residency. The
Purchaser is organized under the laws of the jurisdiction set forth beneath such Purchaser’s name on the signature page attached
hereto, and its principal place of operations is in the state set forth beneath such Purchaser’s name on the signature page
attached hereto.


(f)


General Solicitation.
The Purchaser is not purchasing the Units as a result of any advertisement, article, notice or other communication regarding the
Units published in any newspaper, magazine or similar media or broadcast over the television or radio or presented at any seminar
or any other general solicitation or general advertisement. Prior to the time that the Purchaser was first contacted by the Company
or the Placement Agent such Purchaser had a pre-existing and substantial relationship with the Company or the Placement Agent.


(g)


Regulation M Confirmation
and Compliance With Registration Statement. The Purchaser is aware that the anti-manipulation rules of Regulation M under
the Exchange Act, may apply to sales of the Registrable Securities registered under the Registration Statement and other activities
with respect to the Securities by Purchaser. The Purchaser agrees to sell all Registrable Securities registered under the Registration
Statement and sold in connection therewith, in compliance with the plan of distribution set forth in such Registration Statement
and any and all applicable prospectus delivery requirements.


(h)


Opportunity to Ask
Questions. The Purchaser has had an opportunity to ask questions of and receive satisfactory answers from the Company, or persons
acting on behalf of the Company, concerning the terms and conditions of the Securities and the Company, and all such questions
have been answered to the full satisfaction of the Purchaser.


3.4


No Investment,
Tax or Legal Advice. Each Purchaser understands that nothing in the Company SEC Documents, this Agreement, or any other materials
presented to the Purchaser in connection with the purchase and sale of the Units constitutes legal, tax or investment advice.
Each Purchaser has consulted such legal, tax and investment advisors as it, in its sole discretion, has deemed necessary or appropriate
in connection with its purchase of Units. 






    	 		Page 13



    	 



    

 


3.5


Additional Acknowledgement.
Each Purchaser acknowledges that it has independently evaluated the merits of the transactions contemplated by this Agreement,
that it has independently determined to enter into the transactions contemplated hereby, that it is not relying on any advice from
or evaluation by any other person. Each Purchaser acknowledges that the Placement Agent has acted solely as placement agent for
the Company in connection with the Offering of the Units by the Company, that the information and data provided to the Purchaser
in connection with the transaction contemplated hereby has not been subjected to independent verification by the Placement Agent,
and that the Placement Agent has made no representation or warranty whatsoever with respect to the accuracy or completeness of
such information, data or other related disclosure material. Each Purchaser acknowledges that it has not taken any actions that
would deem the Purchasers to be members of a “group” for purposes of Section 13(d) of the Exchange Act.


3.6


Limited Ownership.
The purchase of the Units issuable to each Purchaser at the Closing will not result in such Purchaser (individually or together
with any other person or entity with whom such Purchaser has identified, or will have identified, itself as part of a “group”
in a public filing made with the SEC involving the Company’s securities) acquiring, or obtaining the right to acquire, in
excess of 19.999% of the outstanding shares of Common Stock or voting power of the Company on a post-transaction basis that assumes
that the Closing shall have occurred. Such Purchaser does not presently intend to, along or together with others, make a public
filing with the SEC to disclose that it has (or that it together with such other persons or entities have) acquired, or obtained
the right to acquire, as a result of the Closing (when added to any other securities of the Company that it or they then own or
have the right to acquire), in excess of 19.999% of the outstanding shares of Common Stock or the voting power of the Company on
a post-transaction basis that assumes that the Closing shall have occurred.


3.7


Short Sales and
Confidentiality Prior to the Date Hereof. Other than consummating the transactions contemplated hereunder, such Purchaser
has not directly or indirectly, nor has any person or entity acting on behalf of or pursuant to any understanding with such Purchaser,
executed any purchases or sales, including short sales as defined in Rule 200 of Regulation SHO under the Exchange Act (“Short
Sales”), of the securities of the Company during the period commencing from the time that such Purchaser first received
a term sheet (written or oral) from the Company or any other person representing the Company setting forth the material terms
of the transactions contemplated hereunder until the date hereof (“Discussion Time”). Notwithstanding the foregoing,
in the case of a Purchaser that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions
of such Purchaser’s assets and the portfolio managers have no direct knowledge of the investment decisions made by the portfolio
managers managing other portions of such Purchaser’s assets, the representation set forth above shall only apply with respect
to the portion of assets managed by the portfolio manager that made the investment decision to purchase the securities covered
by this Agreement. Other than to other persons party to this Agreement, such Purchaser has maintained the confidentiality of all
disclosures made to it in connection with this transaction (including the existence and terms of this transaction). Notwithstanding
the foregoing, for avoidance of doubt, nothing contained herein shall constitute a representation or warranty, or preclude any
actions, with respect to the identification of the availability of, or securing of, available shares to borrow in order to effect
short sales or similar transactions in the future.


4.

4.1

C Preferred Holder. The Company shall have received the consent and approval of the Series C Preferred holder for the designation
of the Preferred Stock and the liquidation preference set forth therein.


5.


Additional Covenants.


5.1


Reporting Status.
With a view to making available to the Purchasers the benefits of certain rules and regulations of the SEC which may permit
the sale of the Securities to the public without registration, the Company agrees to use commercially reasonable efforts to file
with the SEC, in a timely manner all reports and other documents required of the Company under the Exchange Act. The Company will
otherwise take such further action as a Purchaser may reasonably request, all to the extent required from time to time to enable
such Purchaser to sell the Securities without registration under the Securities Act or any successor rule or regulation adopted
by the SEC. If, at any time during the period commencing from the six-month anniversary of the date hereof and ending at such time
that all Registrable Securities (as defined below) may be sold without the requirement for the Company to be in compliance with
Rule 144(c)(1) and otherwise without restriction or limitation pursuant to Rule 144 (the “144 Sale Date”), the
Company fails to satisfy the current public information requirement of Rule 144(c) under the Securities Act, then the Company shall,
on the business day immediately following such failure and each 30th day thereafter until the 144 Sale Date, make a
payment to the Purchasers as partial liquidated damages for such failure equal to 1% of the Purchase Price paid for the Units and
Underlying Shares then owned by the Purchasers. Payments pursuant to this Section 5.1 will be prorated on a daily basis during
each 30-day period and will be paid to the Purchasers by wire transfer or check within five business days after the earlier of
(i) the end of each 30-day period following such failure to satisfy the current public information requirement or (ii) the
144 Sale Date. If the Company fails to pay any liquidated damages pursuant to this section in full within seven days after the
date payable, the Company will pay interest thereon at a rate of 12% per annum (or such lesser maximum amount that is permitted
to be paid by applicable law) to the Purchasers, accruing daily from the date such liquidated damages are due until such amounts,
plus all such interest thereon, are paid in full.

5.2


Listing. So
long as a Purchaser owns any of the Securities, the Company will use commercially reasonable efforts to maintain the listing of
its Common Stock, including the Underlying Shares, on the Principal Market or an alternative listing on the New York Stock Exchange
or the NYSE MKT, or any successor market, as applicable, and will comply in all material respects with the Company’s reporting,
filing and other obligations under the bylaws or rules of such exchanges, as applicable.


5.3


Adjustments in
Share Numbers and Prices.  In the event of any stock split, subdivision, dividend or distribution payable in shares of Common
Stock (or other securities or rights convertible into, or entitling the holder thereof to receive directly or indirectly shares
of Common Stock), combination or other similar recapitalization or event occurring after the date hereof, each reference in this
Agreement to a number of shares or price per share shall be amended appropriately to account for such event.


5.4


Non-Public Information.
The Company covenants and agrees that neither it nor any other person acting on its behalf will provide any Purchaser or its
agents or counsel with any information that the Company believes constitutes material non-public information, unless prior thereto
such Purchaser shall have executed a written agreement regarding the confidentiality and use of such information. The Company understands
and confirms that each Purchaser shall be relying on the foregoing representations in effecting transactions in securities of the
Company. Furthermore, if the Company has disclosed any material non-public information to the Purchaser, the Purchaser has no duty
to keep such information confidential following the public announcement of this transaction.


5.5


Restrictions on
Future Transactions. The Company will not, from the date of this Agreement through the date that is 90 days after the date
the Registration Statement (as defined below) becomes effective (the “Lock-Up Period”), (i) offer, pledge, announce
the intention to sell, 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 or otherwise transfer or dispose of, directly or indirectly, any shares of Common
Stock or any securities convertible into or exercisable or exchangeable for Common Stock or (ii) enter into any swap or other agreement
that transfers, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such transaction
described in clause (i) or (ii) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise,
except (1) pursuant to this Agreement, (2) pursuant to employee stock option or equity plans as existing on the date of this Agreement
and filed as an exhibit to or incorporated by reference in the Company SEC Documents, (3) pursuant to acquisitions of businesses
or assets in transactions approved by the Company’s Board of Directors that are not for the primary purpose of raising capital
or (4) upon the exercise of warrants or the conversion or exchange of convertible or exchangeable securities outstanding as of
the date of this Agreement and filed as an exhibit to or incorporated by reference in or described or referenced in the Company
SEC Documents in accordance with the terms of such securities as of the date hereof. The Company agrees not to accelerate the vesting
of any option or warrant or the lapse of any repurchase right prior to the expiration of the Lock-Up Period. Except to the extent
necessary to comply with the Company’s obligations hereunder and the registration rights set forth in the SEC Documents,
the Company will not file any registration statement during the Lock-up Period. The Company has caused to be delivered to the Placement
Agent prior to the date of this Agreement a letter, in the form of Exhibit F hereto (the “Lock-Up Agreement”),
from each of the Company’s directors and officers. The Company will enforce the terms of each Lock-Up Agreement and issue
stop-transfer instructions to the transfer agent for the Common Stock with respect to any transaction or contemplated transaction
that would constitute a breach of or default under the applicable Lock-Up Agreement.


5.6


Restriction on
Variable Rate Transactions. From the date hereof until the one-year anniversary of the Closing Date, the Company shall be
prohibited from effecting or entering into an agreement to effect any issuance by the Company or any of its subsidiaries of Common
Stock or any outstanding convertible instruments, options or warrants or similar securities (or a combination of units thereof)
involving a Variable Rate Transaction. “Variable Rate Transaction” means a transaction in which the Company
(i) issues or sells any debt or equity securities that are convertible into, exchangeable or exercisable for, or include the right
to receive additional shares of Common Stock either (A) at a conversion price, exercise price 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 debt or equity 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 debt or equity security 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 or (ii) enters into any
agreement, including, but not limited to, an agreement for an equity line of credit or “at-the-market” offering, whereby
the Company may issue securities at a future determined price (other than standard and customary “preemptive” or “participation”
rights and excluding any agreement by the Company to issue shares of its Common Stock as consideration in an acquisition, merger
or similar business combination transaction). For the avoidance of doubt, the issuance of a security which is subject to customary
anti-dilution protections, including where the conversion, exercise or exchange price is subject to adjustment as a result of
stock splits, reverse stock splits and other similar recapitalization or reclassification events, shall not be deemed to be a
“Variable Rate Transaction.” Any Purchaser 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.


5.7


Equal Treatment
of Purchasers. No consideration (including any modification of this Agreement and any other documents or agreements executed
in connection with the transaction contemplated hereunder) shall be offered or paid to any person to amend or consent to a waiver
or modification of any provision of this Agreement unless the same consideration is also offered to all of the parties to this
Agreement. For clarification purposes, this provision constitutes a separate right granted to each Purchaser by the Company and
negotiated separately by each Purchaser, and is intended for the Company to treat the Purchasers as a class and shall not in any
way be construed as the Purchasers acting in concert or as a group with respect to the purchase, disposition or voting of securities
of the Company or otherwise.

6.


Registration Rights.



6.1


Registration Procedures
and Expenses. 


(a)


The Company shall
prepare and file with the SEC, as promptly as reasonably practicable following Closing, but in no event later than 30 days following
Closing, a registration statement on Form S-1 (or any successor to Form S-1), covering the resale of the Registrable Securities
(as defined below) (the “S-1 Registration Statement”) and as soon as reasonably practicable thereafter, but
in no event later than 90 days following Closing (120 days following Closing in the event of a “full review” of the
Registration Statement by the SEC) (the “Required Effective Date”), effect such registration and any related
qualification or compliance with respect to all Registrable Securities held by the Purchasers. For purposes of this Agreement,
the term “Registrable Securities” shall mean (i) the Underlying Shares and (ii) any Common Stock of the Company
issued as (or issuable upon the conversion or exercise of any warrant, right or other security which is issued as) a dividend
or other distribution with respect to, or in exchange for or in replacement of, any Underlying Shares, subject to reductions in
the Registrable Securities pursuant to the limitations described below in connection with a Reduction in Registrable Securities.
In the event that Form S-1 (or any successor form) is or becomes unavailable to register the resale of the Registrable Securities
at any time prior to the expiration of the Purchasers’ registration rights pursuant to Section 6.1(b)(i), the Company shall
prepare and file with the SEC, as promptly as reasonably practicable following the date that Form S-1 is no longer available to
register the Registrable Securities (or unsold portion thereof) a registration statement on any successor to Form S-1 covering
the resale of the Registrable Securities (the “Successor Registration Statement”), provided that if any time
in the future Form S-3 becomes available to the Company to register the Registrable Securities, the Company may amend the S-1
Registration Statement to instead be on Form S-3 (the “S-3 Registration Statement” and collectively the S-3 Registration
Statement, the Successor Registration Statement and the S-1 Registration Statement, the “Registration Statement”)
and as soon as reasonably practicable thereafter to effect registration of the Registrable Securities (or any unsold portion thereof)
and any related qualification or compliance with respect to all Registrable Securities held by the Purchasers. If the Registration
Statement has not been declared effective by the SEC on or before the Required Effective Date, or if, after the Registration Statement
has been declared effective, it ceases to be effective and available for use for more than (y) 10 consecutive trading days, or
(z) an aggregate of 45 days (which need not be consecutive) during any 12-month period, the Company shall, on the business day
immediately following the Required Effective Date and each 30th day thereafter, make a payment to the Purchasers as
partial liquidated damages for such delay (together, the “Late Registration Payments”) equal to 1% of the Purchase
Price paid for the Units then owned by the Purchasers until the Registration Statement is declared effective by the SEC, up to
an annual maximum of 6% of the aggregate Purchase Price. Late Registration Payments will be prorated on a daily basis during each
30-day period and will be paid to the Purchasers by wire transfer or check within five business days after the earlier of (i) the
end of each 30-day period following the Required Effective Date or (ii) the effective date of the Registration Statement.
If the Company fails to pay any liquidated damages pursuant to this section in full within seven days after the date payable,
the Company will pay interest thereon at a rate of 12% per annum (or such lesser maximum amount that is permitted to be paid by
applicable law) to the Purchasers, accruing daily from the date such liquidated damages are due until such amounts, plus all such
interest thereon, are paid in full. “Business day” means any day except Saturday, Sunday and any day that is
a federal legal holiday in the United States. Notwithstanding the obligations set forth above, if (i) any SEC guidance; or (ii)
any comments received from the SEC, sets forth a limitation on the number of securities permitted to be registered on behalf of
the Purchaser in the Registration Statement (provided that the Company shall not be prohibited from including the resale of other
securities on such Registration Statement), the number of Registrable Securities to be included on such Registration Statement
for the benefit of all of the Purchasers will be reduced pro rata between the Purchasers whose securities are included in such
Registration Statement and all Conversion Shares shall be registered prior to all Warrant Shares (a “Limitation in Registrable
Securities”). In the case of a Limitation in Registrable Securities, the Company shall take action to file additional
registration statements at the written request of the holders of a majority in interest of the Preferred Stock shares after the
effectiveness of the Registration Statement, subject to SEC rules and guidance and the requirements set forth above, provided,
however, that the Company shall not be required to file more than one additional Registration Statement in any rolling six month
period. For the sake of clarity, the Registrable Securities required to be included in the Registration Statement shall be the
total Registrable Securities reduced by any Limitation in Registrable Securities.

(b)


The Company shall
use its commercially reasonable best efforts to:


(i)


prepare and file
with the SEC such amendments and supplements to the Registration Statement and the prospectus forming part thereof (the “Prospectus”)
used in connection therewith as may be necessary or advisable to keep the Registration Statement current and effective for the
Registrable Securities held by a Purchaser for a period ending on the earliest of (i) the second anniversary of the Closing Date,
(ii) the date on which all Registrable Securities may be sold pursuant to Rule 144 under the Securities Act or any successor rule
(“Rule 144”) during any three-month period without the requirement for the Company to be in compliance with
the current public information required under Rule 144(c)(1) or (iii) such time as all Registrable Securities have been sold pursuant
to a registration statement or Rule 144. At such time the Company is no longer required to keep the Registration Statement current
and effective for the Registrable Securities held by a Purchaser (the “Registration Statement Termination Date”),
that Purchaser will no longer accrue any additional liquidated damages payments pursuant to Sections 6.1(a) or 6.2(c); however,
the Company shall still be obligated to make all payments under Sections 6.1(a) or 6.2(c) that were not made prior to the Registration
Statement Termination Date for that Purchaser. The Company shall notify each Purchaser promptly upon the Registration Statement
and each post-effective amendment thereto, being declared effective by the SEC and advise each Purchaser that the form of Prospectus
contained in the Registration Statement or post-effective amendment thereto, as the case may be, at the time of effectiveness meets
the requirements of Section 10(a) of the Securities Act or that it intends to file a Prospectus pursuant to Rule 424(b) under the
Securities Act that meets the requirements of Section 10(a) of the Securities Act;


(ii)


furnish to the Purchaser
with respect to the Registrable Securities registered under the Registration Statement such number of copies of the Registration
Statement and the Prospectus (including supplemental prospectuses) filed with the SEC in conformance with the requirements of the
Securities Act and other such documents as the Purchaser may reasonably request, in order to facilitate the public sale or other
disposition of all or any of the Registrable Securities by the Purchaser;


(iii)


make any necessary
blue sky filings;


(iv)


pay the expenses
incurred by the Company and the Purchasers in complying with Section 6, including, all registration and filing fees, FINRA fees,
exchange listing fees, printing expenses, fees and disbursements of counsel for the Company, blue sky fees and expenses and the
expense of any special audits incident to or required by any such registration (but excluding attorneys’ fees of any Purchaser
and any and all underwriting discounts and selling commissions applicable to the sale of Registrable Securities by the Purchasers);


(v)


advise the Purchasers,
promptly after it shall receive notice or obtain knowledge of the issuance of any stop order by the SEC delaying or suspending
the effectiveness of the Registration Statement or of the initiation of any proceeding for that purpose; and it will promptly use
its commercially reasonable best efforts to prevent the issuance of any stop order or to obtain its withdrawal at the earliest
possible moment if such stop order should be issued; and






    	 		Page 19



    	 



    

 


(vi)


with a view to making
available to the Purchaser the benefits of Rule 144 and any other rule or regulation of the SEC that may at any time permit the
Purchaser to sell Registrable Securities to the public without registration, the Company covenants and agrees to use its commercially
reasonable efforts to: (i) make and keep public information available, as those terms are understood and defined in Rule 144, until
the earlier of (A) such date as all of the Registrable Securities qualify to be resold immediately pursuant to Rule 144 or any
other rule of similar effect during any three-month period without the requirement for the Company to be in compliance with the
current public information required under Rule 144(c)(1) or (B) such date as all of the Registrable Securities shall have been
resold pursuant to Rule 144 (and may be further resold without restriction); (ii) file with the SEC in a timely manner all
reports and other documents required of the Company under the Securities Act and under the Exchange Act; and (iii) furnish to the
Purchaser upon request, as long as the Purchaser owns any Registrable Securities, (A) a written statement by the Company as to
whether it has complied with the reporting requirements of the Securities Act and the Exchange Act, (B) a copy of the Company’s
most recent Annual Report on Form 10-K or Quarterly Report on Form 10-Q, and (C) such other information as may be reasonably requested
in order to avail the Purchaser of any rule or regulation of the SEC that permits the selling of any such Registrable Securities
without registration.


(c)


The Company shall
not less than three (3) business days prior to the filing of a Registration Statement and not less than one (1) business day prior
to the filing of any related Prospectus or any amendment or supplement thereto (except for Annual Reports on Form 10-K, Quarterly
Reports on Form 10-Q and Current Reports on Form 8-K and any similar or successor reports and except for amendments which do not
materially amend the disclosures included in any immediately prior filing relating to the Purchasers or the securities registered
therein), furnish to the Purchaser copies of such Registration Statement, Prospectus or amendment or supplement thereto, as proposed
to be filed, which documents will be subject to the review of such Purchaser (it being acknowledged and agreed that if a Purchaser
does not object to or comment on the aforementioned documents within such three (3) business day or one (1) business day period,
as the case may be, then the Purchaser shall be deemed to have consented to and approved the use of such documents). The Company
shall not file any Registration Statement or amendment or supplement thereto in a form to which a Purchaser reasonably objects
in good faith, provided that, the Company is notified of such objection in writing within the three (3) business day or one (1)
business day period described above, as applicable.


The Company understands
that the Purchasers disclaim being an underwriter, but acknowledges that a determination by the SEC that a Purchaser is deemed
an underwriter shall not relieve the Company of any obligations it has hereunder.


6.2


Transfer of Shares
After Registration; Suspension. 


(a)


Except in the event
that Section 6.2(b) applies, the Company shall: (i) if deemed necessary or advisable by the Company, prepare and file from time
to time with the SEC a post-effective amendment to the Registration Statement or a supplement to the related Prospectus or a supplement
or amendment to any document incorporated therein by reference or file any other required document so that such Registration Statement
will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary
to make the statements therein not misleading, and so that, as thereafter delivered to purchasers of the Registrable Securities
being sold thereunder, such Prospectus will not contain an untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were
made, not misleading; (ii) provide the Purchasers copies of any documents filed pursuant to Section 6.2(a)(i); and (iii) upon
request, inform each Purchaser who so requests that the Company has complied with its obligations in Section 6.2(b)(i) (or that,
if the Company has filed a post-effective amendment to the Registration Statement which has not yet been declared effective, the
Company will notify the Purchaser to that effect, will use its commercially reasonable best efforts to secure the effectiveness
of such post-effective amendment as promptly as possible and will promptly notify the Purchaser pursuant to Section 6.2(b)(i)
when the amendment has become effective).






    	 		Page 20



    	 



    

 


(b)


Subject to Section
6.2(c), in the event: (i) of any request by the SEC or any other federal or state governmental authority during the period of effectiveness
of the Registration Statement for amendments or supplements to the Registration Statement or related Prospectus or for additional
information; (ii) of the issuance by the SEC or any other federal or state governmental authority of any stop order suspending
the effectiveness of the Registration Statement or the initiation of any proceedings for that purpose; (iii) of the receipt by
the Company of any notification with respect to the suspension of the qualification or exemption from qualification of any of the
Registrable Securities for sale in any jurisdiction or the initiation of any proceeding for such purpose; or (iv) of any event
or circumstance which necessitates the making of any changes in the Registration Statement or Prospectus, or any document incorporated
or deemed to be incorporated therein by reference, so that, in the case of the Registration Statement, it will not contain any
untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements
therein not misleading, and that in the case of the Prospectus, it will not contain any untrue statement of a material fact or
omit 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; then the Company shall promptly deliver a certificate in writing to the Purchasers
(the “Suspension Notice”) to the effect of the foregoing and, upon receipt of such Suspension Notice, the Purchasers
will refrain from selling any Registrable Securities pursuant to the Registration Statement (a “Suspension”)
until the Purchasers are advised in writing by the Company that the current Prospectus may be used, and have received copies from
the Company of any additional or supplemental filings that are incorporated or deemed incorporated by reference in any such Prospectus.
Such Suspension Notice shall not contain any material non-public information. In the event of any Suspension, the Company will
use its best efforts to cause the use of the Prospectus so suspended to be resumed as soon as reasonably practicable after delivery
of a Suspension Notice to the Purchasers. In addition to and without limiting any other remedies (including, without limitation,
at law or at equity) available to the Company and the Purchaser, the Company and the Purchasers shall be entitled to specific performance
in the event that the other party fails to comply with the provisions of this Section 6.2(b).


(c)


Notwithstanding the
foregoing paragraphs of this Section 6.2, the Company shall use its commercially reasonable best efforts to ensure that (i) a Suspension
shall not exceed 10 days individually, (ii) Suspensions covering no more than 45 days, in the aggregate, shall occur during any
twelve-month period and (iii) each Suspension shall be separated by a period of at least 30 days from a prior Suspension (each
Suspension that satisfies the foregoing criteria being referred to herein as a “Qualifying Suspension”). In
the event that there occurs a Suspension (or part thereof) that does not constitute a Qualifying Suspension, the Company shall
pay to the Purchaser the amounts set forth in Section 6.1(a).


(d)


If a Suspension is
not then in effect, the Purchasers may sell Registrable Securities under the Registration Statement, provided that they sell such
Registrable Securities during such time that the registration statement is effective and not withdrawn or suspended and only as
permitted by such registration statement, and provided that they comply with any applicable prospectus delivery requirements. Upon
receipt of a request therefor, the Company will provide an adequate number of current Prospectuses to a Purchaser and to any other
parties reasonably requiring such Prospectuses.


(e)


The Company agrees
that it shall, immediately prior to the Registration Statement being declared effective, deliver to its transfer agent an opinion
letter of counsel, opining that at any time the Registration Statement is effective, the transfer agent may issue, in connection
with the sale of the Registrable Securities, certificates representing such Registrable Securities without restrictive legend,
provided the Registrable Securities are to be sold pursuant to the prospectus contained in the Registration Statement and applicable
prospectus delivery requirements. Upon receipt of such opinion, the Company shall cause the transfer agent to confirm that no further
opinion of counsel is required at the time of transfer in order to issue such Registrable Securities without restrictive legend.






    	 		Page 21



    	 



    

 


The Company shall
cause its transfer agent to issue a certificate without any restrictive legend to a purchaser of any Registrable Securities from
the Purchasers, if no Suspension is in effect at the time of sale, and (a) the sale of such Registrable Securities is registered
under the Registration Statement (including registration pursuant to Rule 415 under the Securities Act); (b) the holder has provided
the Company with an opinion of counsel, in form, substance and scope customary for opinions of counsel in comparable transactions,
to the effect that a public sale or transfer of such Registrable Securities may be made without registration under the Securities
Act; or (c) such Registrable Securities are or may be sold in compliance with Rule 144 under the Securities Act.


6.3


Indemnification.
For the purpose of this Section 6.3:


(a)


the term “Selling
Stockholder” shall mean a Purchaser, its general partners, managing members, managers, executive officers and directors
and each person, if any, who controls that Purchaser within the meaning of Section 15 of the Securities Act or Section 20 of the
Exchange Act;


(b)


the term “Registration
Statement” shall include any final Prospectus, exhibit, supplement or amendment included in or relating to, and any document
incorporated by reference in, the Registration Statement (or deemed to be a part thereof) referred to in Section 6.1; and


(c)


the term “untrue
statement” shall mean any untrue statement or alleged untrue statement of a material fact, or any omission or alleged
omission to state in the Registration Statement 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.


(d)


The Company agrees
to indemnify and hold harmless each Selling Stockholder from and against any losses, claims, damages or liabilities to which such
Selling Stockholder may become subject (under the Securities Act or otherwise) insofar as such losses, claims, damages or liabilities
(or actions or proceedings in respect thereof) arise out of, or are based upon (i) any untrue statement of a material fact contained
in the Registration Statement, (ii) any inaccuracy in the representations and warranties of the Company contained in this Agreement
or the failure of the Company to perform its obligations hereunder or (iii) any failure by the Company to fulfill any undertaking
included in the Registration Statement, and the Company will reimburse such Selling Stockholder for any reasonable legal expense
or other actual accountable out of pocket expenses reasonably incurred in investigating, defending or preparing to defend any such
action, proceeding or claim; provided, however, that the Company shall not be liable in any such case to the extent that such loss,
claim, damage or liability arises out of, or is based upon, an untrue statement made in such Registration Statement in reliance
upon and in conformity with written information furnished to the Company by or on behalf of such Selling Stockholder specifically
for use in preparation of the Registration Statement or the failure of such Selling Stockholder to comply with its covenants and
agreements contained herein or any statement or omission in any Prospectus that is corrected in any subsequent Prospectus that
was delivered to the Selling Stockholder prior to the pertinent sale or sales by the Selling Stockholder.


(e)


Each Purchaser severally
(as to itself), and not jointly, agrees to indemnify and hold harmless the Company (and each person, if any, who controls the
Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, each officer of the Company
who signs the Registration Statement and each director of the Company) from and against any losses, claims, damages or liabilities
to which the Company (or any such officer, director or controlling person) may become subject (under the Securities Act or otherwise),
insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of, or are based
upon, (i) any failure by that Purchaser to comply with the covenants and agreements contained in this Section 6 or (ii) any untrue
statement of a material fact contained in the Registration Statement if, and only if, such untrue statement was made in reliance
upon and in conformity with written information furnished by or on behalf of that Purchaser specifically for use in preparation
of the Registration Statement, and that Purchaser will reimburse the Company (or such officer, director or controlling person,
as the case may be), for any reasonable legal expense or other reasonable actual accountable out-of-pocket expenses reasonably
incurred in investigating, defending or preparing to defend any such action, proceeding or claim. The obligation to indemnify
shall be limited to the net amount of the proceeds received by the Purchaser from the sale of the Registrable Securities pursuant
to the Registration Statement.






    	 		Page 22



    	 



    

 


(f)


Promptly after receipt
by any indemnified person of a notice of a claim or the beginning of any action in respect of which indemnity is to be sought against
an indemnifying person pursuant to this Section 6.3, such indemnified person shall notify the indemnifying person in writing of
such claim or of the commencement of such action, but the omission to so notify the indemnifying party will not relieve it from
any liability which it may have to any indemnified party under this Section 6.3 (except to the extent that such omission materially
and adversely affects the indemnifying party’s ability to defend such action) or from any liability otherwise than under
this Section 6.3. Subject to the provisions hereinafter stated, in case any such action shall be brought against an indemnified
person, the indemnifying person shall be entitled to participate therein, and, to the extent that it shall elect by written notice
delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, shall be entitled
to assume the defense thereof, with counsel reasonably satisfactory to such indemnified person. After notice from the indemnifying
person to such indemnified person of its election to assume the defense thereof (unless it has failed to assume the defense thereof
and appoint counsel reasonably satisfactory to the indemnified party), such indemnifying person shall not be liable to such indemnified
person for any legal expenses subsequently incurred by such indemnified person in connection with the defense thereof; provided,
however, that if there exists or shall exist a conflict of interest that would make it inappropriate, in the reasonable opinion
of counsel to the indemnified person, for the same counsel to represent both the indemnified person and such indemnifying person
or any affiliate or associate thereof, the indemnified person shall be entitled to retain its own counsel (who shall not be the
same as the opining counsel) at the expense of such indemnifying person; provided, however, that no indemnifying person shall be
responsible for the fees and expenses of more than one separate counsel (together with appropriate local counsel) for all indemnified
parties. In no event shall any indemnifying person be liable in respect of any amounts paid in settlement of any action unless
the indemnifying person shall have approved the terms of such settlement; provided that such consent shall not be unreasonably
withheld. No indemnifying person shall, without the prior written consent of the indemnified person, effect any settlement of any
pending or threatened proceeding in respect of which any indemnified person is or could reasonably have been a party and indemnification
could have been sought hereunder by such indemnified person, unless such settlement includes an unconditional release of such indemnified
person from all liability on claims that are the subject matter of such proceeding.


(g)


If the indemnification
provided for in this Section 6.3 is unavailable to or insufficient to hold harmless an indemnified party under subsection (d)
or (e) above in respect of any losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred
to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect
the relative fault of the Company on the one hand and the liable Purchaser on the other in connection with the statements or omissions
or other matters which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any
other relevant equitable considerations. The relative fault shall be determined by reference to, among other things, in the case
of an untrue statement, whether the untrue statement relates to information supplied by the Company on the one hand or the liable
Purchaser on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or
prevent such untrue statement. The Company and the Purchasers agree that it would not be just and equitable if contribution pursuant
to this subsection (g) were determined by pro rata allocation (even if the Purchasers were treated as one entity for such purpose)
or by any other method of allocation which does not take into account the equitable considerations referred to above in this subsection
(g). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions
in respect thereof) referred to above in this subsection (g) shall be deemed to include any legal or other expenses reasonably
incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the
provisions of this subsection (g), no Purchasers shall be required to contribute any amount in excess of the amount by which the
net amount received by that Purchaser from the sale of the Registrable Securities to which such loss relates exceeds the amount
of any damages which that Purchaser has otherwise been required to pay to the Company by reason of such untrue statement. No person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution
from any person who was not guilty of such fraudulent misrepresentation. The Purchasers’ obligations in this subsection
to contribute are several in proportion to their sales of Registrable Securities to which such loss relates and not joint.

(h)


The parties to this
Agreement hereby acknowledge that they are sophisticated business persons who were represented by counsel during the negotiations
regarding the provisions hereof including, without limitation, the provisions of this Section 6.3, and are fully informed regarding
said provisions. They further acknowledge that the provisions of this Section 6.3 fairly allocate the risks in light of the ability
of the parties to investigate the Company and its business in order to assure that adequate disclosure is made in the Registration
Statement as required by the Securities Act and the Exchange Act.


(i)


The obligations of
the Company and of the Purchasers under this Section 6.3 shall survive completion of any offering of Registrable Securities in
such Registration Statement for a period of two years from the completion of such offering. No indemnifying party, in the defense
of any such claim or litigation, shall, except with the consent of each indemnified party, consent to entry of any judgment or
enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such
indemnified party of a release from all liability in respect to such claim or litigation.


6.4


Termination of
Conditions and Obligations. The conditions precedent imposed by Section 3 or this Section 6 upon the transferability of the
Registrable Securities shall cease and terminate as to any particular number of the Registrable Securities when such Registrable
Securities shall have been effectively registered under the Securities Act and sold or otherwise disposed of in accordance with
the intended method of disposition set forth in the Registration Statement covering such Registrable Securities or at such time
as an opinion of counsel satisfactory to the Company shall have been rendered to the effect that such conditions are not necessary
in order to comply with the Securities Act. The Company shall request an opinion of counsel promptly upon receipt of a request
therefor from Purchaser.


6.5


Information Available.
So long as the Registration Statement is effective covering the resale of Registrable Securities owned by a Purchaser, the
Company will furnish (or, to the extent such information is available electronically through the Company’s filings with the
SEC, the Company will make available via the SEC’s EDGAR system or any successor thereto) to each Purchaser:


(a)


as soon as practicable
after it is available, one copy of (i) its Annual Report to Stockholders (which Annual Report shall contain financial statements
audited in accordance with generally accepted accounting principles by a national firm of certified public accountants) and (ii)
if not included in substance in the Annual Report to Stockholders, its Annual Report on Form 10-K (the foregoing, in each case,
excluding exhibits);


(b)


upon the request
of the Purchaser, all exhibits excluded by the parenthetical to subparagraph (a)(ii) of this Section 6.5 as filed with the SEC
and all other information that is made available to stockholders; and


(c)


upon the reasonable
request of the Purchaser, an adequate number of copies of the Prospectuses to supply to any other party requiring such Prospectuses;
and the Company, upon the reasonable request of a Purchaser, will meet with each Purchaser or a representative thereof at the
Company’s headquarters during the Company’s normal business hours to discuss all information relevant for disclosure
in the Registration Statement covering the Registrable Securities and will otherwise reasonably cooperate with the Purchasers
conducting an investigation for the purpose of reducing or eliminating the Purchasers’ exposure to liability under the Securities
Act, including the reasonable production of information at the Company’s headquarters; provided, that the Company shall
not be required to disclose any confidential information to or meet at its headquarters with a Purchaser until and unless that
Purchaser shall have entered into a confidentiality agreement in form and substance reasonably satisfactory to the Company with
the Company with respect thereto.

6.6


Public Statements;
Limitation on Information. The Company agrees to disclose on a Current Report on Form 8-K the existence of the Offering and
the material terms, thereof, including pricing, within one business day after the date hereof. Such Current Report on Form 8-K
shall include a form of this Agreement (and all exhibits and schedules thereto) as an exhibit thereto. The Company will not issue
any public statement, press release or any other public disclosure listing a Purchaser as one of the purchasers of the Units, or
otherwise naming the Purchaser or its affiliates or investment advisers, without that Purchaser’s prior written consent,
except as may be required by applicable law or rules of any exchange on which the Company’s securities are listed. The Company
shall not provide, and shall cause each of its subsidiaries and the respective officers, directors, employees and agents of the
Company and each of its subsidiaries not to provide, the Purchasers with any material nonpublic information regarding the Company
or any subsidiary from and after the date the Company files, or is required by this Section to file, the Current Report on Form
8-K with the SEC without the prior express written consent of the Purchaser.


6.7


Limits on Additional
Issuances. Without limiting the provisions of Section 5.5, the Company will not, for a period of 90 days following the Closing
Date offer for sale or sell any securities unless, in the opinion of the Company’s counsel, such offer or sale does not jeopardize
the availability of exemptions from the registration and qualification requirements under applicable securities laws with respect
to the Offering. Except as disclosed in the SEC Documents, and except for the issuance of equity awards under the Company’s
equity compensation plans, the issuance of Common Stock upon exercise of outstanding options and warrants, the issuance of Common
Stock purchase warrants, the issuance of Common Stock as part of acquisitions approved by the board of directors of the Company,
the issuance of Common Stock upon conversion of outstanding shares of Preferred Stock, the issuance of Series B Stock in-kind to
the holders of the Series B Stock, and the offering contemplated hereby, the Company has not engaged in any offering of equity
securities during the six months prior to the date of this Agreement. The foregoing provisions shall not prevent the Company from
filing a resale registration statement or registration statements under the Securities Act.


6.8


Form D and
State Securities Filings. The Company will file with the SEC a Notice of Sale of Securities on Form D with respect to
the Units, as required under Regulation D under the Securities Act, no later than 15 days after the Closing Date. The Company
will promptly and timely file all documents and pay all filing fees required by any states’ securities laws in connection
with the sale of Securities.


6.9


Assignment of Registration
Rights. The rights to cause the Company to register Registrable Securities pursuant to this Section 6 may be assigned by a
Purchaser to a party that acquires, other than pursuant to the Registration Statement or Rule 144, any of Registrable Securities.


6.10


Selling Stockholder
Questionnaire. Each Purchaser agrees to furnish to the Company a completed questionnaire in the form attached to this Agreement
as Exhibit E (a “Selling Holder Questionnaire”). The Company shall not be required to include the Registrable
Securities of a Purchaser in a Registration Statement and shall not be required to pay any liquidated or other damages hereunder
to any such Purchaser who fails to furnish to the Company a fully completed Selling Holder Questionnaire at least three business
days prior to the filing of the Registration Statement.

6.11


Short Sales and
Confidentiality After the Date Hereof. Each Purchaser, severally and not jointly with the other Purchasers, covenants that
neither it, nor any affiliate acting on its behalf or pursuant to any understanding with it will execute any purchases or sales,
including Short Sales, of any of the Company’s securities during the period commencing with the Discussion Time and ending
at such time the transactions contemplated by this Agreement are first publicly announced. Each Purchaser, severally and not jointly
with the other Purchasers, covenants that until such time as the transactions contemplated by this Agreement are publicly disclosed
by the Company, such Purchaser will maintain the confidentiality of the existence and terms of this transaction. Notwithstanding
the foregoing, and notwithstanding anything contained in this Agreement to the contrary, the Company expressly acknowledges and
agrees that (i) no Purchaser makes any representation, warranty or covenant hereby that it will not engage in effecting transactions
in any securities of the Company after the time that the transactions contemplated by this Agreement are first publicly announced,
(ii) no Purchaser shall be restricted or prohibited from effecting any transactions in any securities of the Company in accordance
with applicable securities laws from and after the time that the transactions contemplated by this Agreement are first publicly
announced and (iii) no Purchaser shall have any duty of confidentiality to the Company or its subsidiaries with respect to the
transactions contemplated by this Agreement after the issuance of the Current Report on Form 8-K as described in Section 6.6. Notwithstanding
the foregoing, in the case of a Purchaser that is a multi-managed investment vehicle whereby separate portfolio managers manage
separate portions of such Purchaser’s assets and the portfolio managers have no direct knowledge of the investment decisions
made by the portfolio managers managing other portions of such Purchaser’s assets, the covenants set forth above shall only
apply with respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase the
securities covered by this Agreement.

Independent Nature
of Purchasers’ Obligations and Rights. The obligations of each Purchaser under this Agreement are several and not joint
with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance of the obligations
of any other Purchaser under this Agreement. Nothing contained herein, and no action taken by any Purchaser pursuant hereto, shall
be deemed to constitute the Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create
a presumption that the Purchasers are in any way acting in concert or as a group with respect to such obligations or the transactions
contemplated by this Agreement. Each Purchaser confirms that it has independently participated in the negotiation of the transaction
contemplated hereby with the advice of its own counsel and advisors. Each Purchaser shall be entitled to independently protect
and enforce its rights, including, without limitation, the rights arising out of this Agreement, and it shall not be necessary
for any other Purchaser to be joined as an additional party in any proceeding for such purpose. It is expressly understood and
agreed that each provision contained in this Agreement is between the Company and a Purchaser, solely, and not between the Company
and the Purchasers collectively and not between and among the Purchasers.

7.12


Termination.
This Agreement may be terminated and the sale and purchase of the Units abandoned at any time prior to the Closing by either the
Company or any Purchaser (with respect to itself only) upon written notice to the other, if the Closing has not been consummated
on or prior to 5:00 p.m., New York City time, on the fifteenth (15th) day following the date of this Agreement; provided,
however, that the right to terminate this Agreement under this Section 7.12 shall not be available to any person whose failure
to comply with its obligations under this Agreement has been the cause of or resulted in the failure of the Closing to occur on
or before such time. Nothing in this Section 7.12 shall be deemed to release any party from any liability for any breach by such
party of the terms and provisions of this Agreement or to impair the right of any party to compel specific performance by any other
party of its obligations under this Agreement. In the event of a termination pursuant to this Section, the Company shall promptly
notify all non-terminating Purchasers. Upon a termination in accordance with this Section, the Company and the terminating Purchaser(s)
shall not have any further obligation or liability (including arising from such termination) to the other, and no Purchaser will
have any liability to any other Purchaser under this Agreement as a result therefrom.

4.999% Blocker:


By marking the box below, the Purchaser
requests and the Company agrees, that this Agreement will contain the following 4.999% “blocker” provision:


☐  Notwithstanding
anything to the contrary contained in this Purchase Agreement or Warrant, (i) the number of Warrant Shares that may be acquired
by the Purchaser (or the Holder as defined in the Warrant) upon any exercise of the Warrant (or otherwise in respect hereof), and
(ii) the number of Conversion Shares that may be acquired by the Purchaser (or the holder of the Preferred Stock transferred from
the Holder) upon the conversion of the Preferred Stock, each shall be limited to the extent necessary to insure that, following
such exercise, conversion or other issuance, the total number of shares of Common Stock then beneficially owned by such Purchaser
(or Holder) and its affiliates and any other persons whose beneficial ownership of Common Stock would be aggregated with the Purchaser’s
(or Holder’s) for purposes of Section 13(d) of the Exchange Act, does not exceed 4.999% of the total number of issued and
outstanding shares of Common Stock (including for such purpose the shares of Common Stock issuable upon such exercise, conversion
or other issuance).  For such purposes, beneficial ownership shall be determined in accordance with Section 13(d) of the Exchange
Act and the rules and regulations promulgated thereunder.  This provision shall not restrict the number of shares of Common
Stock which the Purchaser (or Holder) may receive or beneficially own in order to determine the amount of securities or other consideration
that such Purchaser (or Holder) may receive in the event of a Fundamental Transaction as contemplated in Section 9 of the Warrant
or a Recapitalization Event as contemplated in Section 5 of the Certificate of Designation. By written notice to the Company, the
Purchaser (or Holder) may waive the provisions of this paragraph, but any such waiver will not be effective until the 61st day
after delivery of such notice, nor will any such waiver effect any other holder thereof.

the total number of shares of Common Stock then beneficially owned by such Holder and its affiliates (as defined under Rule 144,
“Affiliates”) and any other persons whose beneficial ownership of Common Stock would be aggregated with the
Holder’s for purposes of Section 13(d) of the Exchange Act, does not exceed 9.999% of the total number of issued and outstanding
shares of Common Stock (including for such purpose the shares of Common Stock issuable upon such exercise).  For such purposes,
beneficial ownership shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated
thereunder.  This provision shall not restrict the number of shares of Common Stock which a Holder may receive or beneficially
own in order to determine the amount of securities or other consideration that such Holder may receive in the event of a Fundamental
Transaction as contemplated in Section 9 of this Warrant.  This restriction may not be waived.


5.


Delivery of Warrant
Shares. 


(a)


To effect exercises
hereunder, the Holder shall not be required to physically surrender this Warrant unless the aggregate Warrant Shares represented
by this Warrant are being exercised. Upon delivery of the Exercise Notice (in the form attached hereto) to the Company (with the
attached Warrant Shares Exercise Log) at its address for notice set forth herein and subject to the payment terms described below,
the Company shall promptly (but in no event later than three Trading Days after the Date of Exercise (as defined herein)) issue
and deliver to the Holder, a certificate for the Warrant Shares issuable upon such exercise, which, shall include restrictive
legends unless the applicable Warrant Shares are (i) registered pursuant to an effective registration statement under the Securities
Act and under applicable state securities or blue sky laws or (ii) eligible for resale without volume or manner-of-sale restrictions
or current public information requirements pursuant to Rule 144 of the Securities Act, provided that the Company may require,
as a condition to the issuance of Warrant Shares exempt from registration pursuant to Rule 144, that the Holder of this Warrant,
comply with applicable requirements to confirm an exemption from registration and provide the Company and/or its legal counsel
with reasonable and customary confirmations in order to confirm compliance with Rule 144. Prior to delivery of the Warrant Shares
(but in no event later than two Trading Days after the Date of Exercise (as defined herein)), the Holder shall have delivered
to the Company, if such Holder is not utilizing the cashless exercise provisions set forth in this Warrant, payment of the Exercise
Price multiplied by the number of Warrant Shares that the Holder intends to purchase hereunder. The Company shall, upon request
of the Holder and subsequent to the date on which a registration statement covering the resale of the Warrant Shares has been
declared effective by the Securities and Exchange Commission, use its reasonable best efforts to deliver Warrant Shares hereunder
electronically through the Depository Trust Corporation or another established clearing corporation performing similar functions,
if available, provided, that, the Company may, but will not be required to change its transfer agent if its current transfer agent
cannot deliver Warrant Shares electronically through the Depository Trust Corporation. A “Date of Exercise”
means the date on which the Holder shall have delivered to the Company the Exercise Notice (with the Warrant Exercise Log attached
to it), appropriately completed and duly signed.

(b)


If by the third Trading
Day after a Date of Exercise the Company fails to deliver the required number of Warrant Shares in the manner required pursuant
to Section 5(a), then the Holder will have the right to rescind such exercise.


(c)


If by the third Trading
Day after a Date of Exercise the Company fails to deliver the required number of Warrant Shares in the manner required pursuant
to Section 5(a), and if after such third Trading Day and prior to the receipt of such Warrant Shares, the Holder purchases (in
an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Holder of the Warrant
Shares which the Holder anticipated receiving upon such exercise (a “Buy-In”), then the Company shall (1) pay
in cash to the Holder the amount by which (x) the Holder’s total purchase price (including brokerage commissions, if any)
for the shares of Common Stock so purchased exceeds (y) the amount obtained by multiplying (A) the number of Warrant Shares that
the Company was required to deliver to the Holder in connection with the exercise at issue by (B) the closing bid price of the
Common Stock at the time of the obligation giving rise to such purchase obligation and (2) at the option of the Holder, either
reinstate the portion of the Warrant and equivalent number of Warrant Shares for which such exercise was not honored or deliver
to the Holder the number of shares of Common Stock that would have been issued had the Company timely complied with its exercise
and delivery obligations hereunder. The Holder shall provide the Company written notice indicating the amounts payable to the Holder
in respect of the Buy-In.


(d)


The Company’s
obligations to issue and deliver Warrant Shares in accordance with the terms hereof are absolute and unconditional, irrespective
of any action or inaction by the Holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery
of any judgment against any person or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination,
or any breach or alleged breach by the Holder or any other person of any obligation to the Company or any violation or alleged
violation of law by the Holder or any other person, and irrespective of any other circumstance which might otherwise limit such
obligation of the Company to the Holder in connection with the issuance of Warrant Shares. Nothing herein shall limit a Holder’s
right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific
performance and/or injunctive relief with respect to the Company’s failure to timely deliver certificates representing Warrant
Shares upon exercise of the Warrant as required pursuant to the terms hereof.


6.


Charges, Taxes and
Expenses. Issuance and delivery of Warrant Shares upon exercise of this Warrant shall be made without charge to the Holder
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 Company; provided, however, that the Company shall not
be required to pay any tax which may be payable in respect of any transfer involved in the registration of any certificates for
Warrant Shares or Warrants in a name other than that of the Holder. The Holder shall be responsible for all other tax liability
that may arise as a result of holding or transferring this Warrant or receiving Warrant Shares upon exercise hereof.


7.


Replacement of Warrant.
If this Warrant is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution
for and upon cancellation hereof, or in lieu of and substitution for this Warrant, a New Warrant, but only upon receipt of evidence
reasonably satisfactory to the Company of such loss, theft or destruction and customary and reasonable indemnity (which shall not
include a surety bond), if requested. Applicants for a New Warrant under such circumstances shall also comply with such other reasonable
regulations and procedures and pay such other reasonable third-party costs as the Company may prescribe. If a New Warrant is requested
as a result of a mutilation of this Warrant, then the Holder shall deliver such mutilated Warrant to the Company as a condition
precedent to the Company’s obligation to issue the New Warrant.






    	 		Page B- 4



    	 



    

 


8.


Reservation of Warrant
Shares. The Company covenants that it will at all times reserve and keep available out of the aggregate of its authorized but
unissued and otherwise unreserved Common Stock, solely for the purpose of enabling it to issue Warrant Shares upon exercise of
this Warrant as herein provided, the number of Warrant Shares which are then issuable and deliverable upon the exercise of this
entire Warrant, free from preemptive rights or any other contingent purchase rights of Persons other than the Holder (taking into
account the adjustments and restrictions of Section 9). The Company covenants that all Warrant Shares so issuable and deliverable
shall, upon issuance and the payment of the applicable Exercise Price in accordance with the terms hereof, be duly and validly
authorized, issued and fully paid and nonassessable.


9.


Certain Adjustments.
The Exercise Price and number of Warrant Shares issuable upon exercise of this Warrant are subject to adjustment from time to time
as set forth in this Section 9.


(a)


Stock Dividends
and Splits. If the Company, at any time while this Warrant is 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 Exercise Price shall be adjusted to equal the product obtained by multiplying the then-current
Exercise Price 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 after 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 after the effective date of such subdivision or combination.


(b)


Fundamental Transactions.
If, at any time while this Warrant is outstanding there is a Fundamental Transaction, then the Holder shall have the right thereafter
to receive, upon exercise of this Warrant, the same amount and kind of securities, cash or property as it would have been entitled
to receive upon the occurrence of such Fundamental Transaction if it had been, immediately prior to such Fundamental Transaction,
the holder of the number of Warrant Shares then issuable upon exercise in full of this Warrant (the “Alternate Consideration”).
For purposes of any such exercise, the determination of the Exercise Price shall be appropriately adjusted to apply to such Alternate
Consideration based on the amount of Alternate Consideration issuable in respect of one share of Common Stock in such Fundamental
Transaction, and the Company shall apportion the Exercise Price among the Alternate Consideration in a reasonable manner reflecting
the relative value of any different components of the Alternate Consideration. If holders of Common Stock are given any choice
as to the securities, cash or property to be received in a Fundamental Transaction, then the Holder shall be given the same choice
as to the Alternate Consideration it receives upon any exercise of this Warrant following such Fundamental Transaction. At the
Holder’s option and request, any successor to the Company or surviving entity in such Fundamental Transaction shall, either
(1) issue to the Holder a new warrant substantially in the form of this Warrant and consistent with the foregoing provisions and
evidencing the Holder’s right to purchase the Alternate Consideration for the aggregate Exercise Price upon exercise thereof,
or (2) purchase the Warrant from the Holder for a purchase price, payable in cash within five Trading Days after such request (or,
if later, on the effective date of the Fundamental Transaction), equal to the Black Scholes Value of the remaining unexercised
portion of this Warrant on the date of such request. The terms of any agreement pursuant to which a Fundamental Transaction is
effected shall include terms requiring any such successor or surviving entity to comply with the provisions of this paragraph (b)
and insuring that the Warrant (or any such replacement security) will be similarly adjusted upon any subsequent transaction analogous
to a Fundamental Transaction.






    	 		Page B- 5



    	 



    

 


(c)


Number of Warrant
Shares. Simultaneously with any adjustment to the Exercise Price pursuant to this Section 9, the number of Warrant Shares that
may be purchased upon exercise of this Warrant shall be increased or decreased proportionately, so that after such adjustment the
aggregate Exercise Price payable hereunder for the adjusted number of Warrant Shares shall be the same as the aggregate Exercise
Price in effect immediately prior to such adjustment.


(d)


Calculations. 
All calculations under this Section 9 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 Company, and the disposition of any such shares shall be considered an issue or sale of Common Stock.


(e)


Notice of Adjustments.
Upon the occurrence of each adjustment pursuant to this Section 9, the Company at its expense will promptly compute such adjustment
in accordance with the terms of this Warrant and prepare a certificate setting forth such adjustment, including a statement of
the adjusted Exercise Price and adjusted number or type of Warrant Shares or other securities issuable upon exercise of this Warrant
(as applicable), describing the transactions giving rise to such adjustments and showing in detail the facts upon which such adjustment
is based. Upon written request, the Company will promptly deliver a copy of each such certificate to the Holder and to the Company’s
Transfer Agent.


10.


Payment of Exercise
Price.  The Holder may pay the Exercise Price in one of the following manners:


(a)


Cash Exercise.
The Holder may deliver immediately available funds; or


(b)


Cashless Exercise.
If an Exercise Notice is delivered at a time when a registration statement permitting the Holder to resell the Warrant Shares is
not then effective or the prospectus forming a part thereof is not then available to the Holder for the resale of the Warrant Shares,
then the Holder may notify the Company in an Exercise Notice of its election to utilize cashless exercise, in which event the Company
shall issue to the Holder the number of Warrant Shares determined as follows:


X = Y [(A-B)/A]  


where:  


X = the
number of Warrant Shares to be issued to the Holder.  


Y = the
number of Warrant Shares with respect to which this Warrant is being exercised.  


A = the average of the Closing
Prices for the five Trading Days immediately prior to (but not including) the Exercise Date.  


B = the Exercise Price.  


For purposes of Rule 144 promulgated
under the Securities Act, it is intended, understood and acknowledged that the Warrant Shares issued in a cashless exercise transaction
shall be deemed to have been acquired by the Holder, and the holding period for the Warrant Shares shall be deemed to have commenced,
on the date this Warrant was originally issued.


11.


No Fractional Shares.
 No fractional shares of Warrant Shares will be issued in connection with any exercise of this Warrant. In lieu of any fractional
shares which would, otherwise be issuable, the Company shall either (a) pay cash equal to the product of such fraction multiplied
by the Closing Price of one Warrant Share on the date of exercise; or (b) issue the Holder one (1) additional share of Common Stock
in lieu of such fractional share.






    	 		Page B- 6



    	 



    

 


12.


Notices.
Any and all notices or other communications or deliveries hereunder (including, without limitation, any Exercise Notice)
shall be in writing and shall be deemed given and effective if provided pursuant to the Purchase Agreement. In
case any time: (1) the Company shall declare any cash dividend on its capital stock; (2) the Company shall pay any dividend
payable in stock upon its capital stock or make any distribution to the holders of its capital stock; (3) the Company shall
offer for subscription pro rata to the holders of its capital stock any additional shares of stock of any class or other
rights; (4) there shall be any capital reorganization, or reclassification of the capital stock of the Company, or
consolidation or merger of the Company with, or sale of all or substantially all of its assets to, another corporation; or
(5) there shall be a voluntary or involuntary dissolution, liquidation or winding up of the Company; then, in any one or more
of said cases, the Company shall give prompt written notice to the Holder. Such notice shall also specify the date as of
which the holders of capital stock of record shall participate in such dividend, distribution or subscription rights, or
shall be entitled to exchange their capital stock for securities or other property deliverable upon such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation or winding up, or conversion or redemption, as the
case may be. Such written notice shall be given at least 20 days prior to the action in question and not less than 20 days
prior to the record date or the date on which the Company’s transfer books are closed in respect thereto.


13.


Registration Rights.
The Holder shall be entitled to the registration rights set forth in Section 6 of the Purchase Agreement.


14.


Miscellaneous. 


(a)


This Warrant shall
be binding on and inure to the benefit of the parties hereto and their respective successors and assigns. Subject to the preceding
sentence, nothing in this Warrant shall be construed to give to any Person other than the Company and the Holder any legal or equitable
right, remedy or cause of action under this Warrant. This Warrant may be amended only in writing signed by the Company and the
Holder and their successors and assigns.

remaining terms and provisions of this Warrant shall not in any way be affected or impaired thereby and the parties will attempt

Exhibit 3.1


 


FORM OF CERTIFICATE OF
DESIGNATION


OF


VERTEX ENERGY, INC.


ESTABLISHING THE DESIGNATION, PREFERENCES,


LIMITATIONS AND RELATIVE RIGHTS OF ITS


SERIES B1 PREFERRED STOCK


 


Pursuant to Section 78.1955
of the Nevada Revised Statutes (the “NRS”), Vertex Energy, Inc., a company organized and existing under
the State of Nevada (the “Corporation”),


 


DOES HEREBY CERTIFY
that pursuant to the authority conferred upon the Board of Directors by the Articles of Incorporation of the Corporation, as amended,
and pursuant to Section 78.1955 of the NRS, the Board of Directors, by unanimous written consent of all members of the Board of
Directors on May 9, 2016, duly adopted a resolution providing for the issuance of 17,000,000 shares of Series B1 Preferred Stock,
which resolution is and reads as follows:


 


RESOLVED, that pursuant
to the authority expressly granted to and invested in the Board of Directors by the provisions of the Articles of Incorporation
of the Corporation, as amended and Section 78.1955 of the NRS, a series of the preferred stock, par value $0.001 per share, of
the Corporation be, and it hereby is, established; and


 


FURTHER RESOLVED,
that the series of preferred stock of the Corporation be, and it hereby is, given the distinctive designation of “Series
B1 Preferred Stock”; and


 


FURTHER RESOLVED,
that the Series B1 Preferred Stock shall consist of 17,000,000 shares; and


 


FURTHER RESOLVED,
that the Series B1 Preferred Stock shall have the powers and preferences, and the relative, participating, optional and other rights,
and the qualifications, limitations, and restrictions thereon set forth in this Certificate of Designation (the “Designation”
or the “Certificate of Designation”):


 


1.                 
Ranking. The Series B1 Preferred Stock shall,
with respect to dividend rights, rights of redemption and rights upon liquidation, winding up or dissolution, rank equally with
the Corporation’s Series B Preferred Stock issued pursuant to that certain Amended and Restated Certificate of
Designation of Vertex Energy, Inc. Establishing the Designation, Preferences, Limitations and Relative Rights of Its Series B Convertible
Preferred Stock, previously filed by the Corporation with the Secretary of State of Nevada on June 23, 2015, as may be amended
from time to time (the “Series B Preferred Stock”), senior to the Common Stock and the Series C Preferred
Stock, and each other class or series of shares of the Corporation that the Corporation may issue in the future the terms of which
do not expressly provide that such class or series ranks equally with, or senior to, the Series B1 Preferred Stock, with respect
to dividend rights, rights of redemption and/or rights upon liquidation, winding up or dissolution.


The Series B1 Preferred
Stock shall, with respect to dividend rights, rights of redemption and rights upon liquidation, winding up or dissolution, rank
equally with each other class or series of shares of the Corporation that the Corporation may issue in the future the terms of
which expressly provide that such class or series shall rank equally with the Series B1 Preferred Stock with respect to dividend
rights, rights of redemption and rights upon liquidation, winding up or dissolution.



    	Vertex Energy: Series B1 Certificate of Designation
	 	12



     

    




The Series B1 Preferred
Stock shall, with respect to dividend rights, rights of redemption and rights upon liquidation, winding up or dissolution, rank
junior to each class or series of shares of the Corporation that the Corporation may issue in the future the terms of which expressly
provide that such class or series shall rank senior to the Series B1 Preferred Stock with respect to dividend rights and rights
upon liquidation, winding up or dissolution. The Series B1 Preferred Stock shall also rank junior to the Senior Securities and
the Corporation’s existing and future indebtedness.


2.                 
Dividends. 


2.1             
Dividends in General. Dividends shall accrue quarterly on the Series B1 Preferred Stock
beginning on the Closing Date, based on the Original Issue Price, at the Dividend Rate, until such Series B1 Preferred Stock is
no longer outstanding either due to conversion, redemption or otherwise as provided herein (“Dividends”).



2.2             
Payment of Dividends. The Corporation shall, in accordance with the terms set forth
herein, pay the Holder of the Series B1 Preferred Stock the Accrued Dividends in cash, in shares of Common Stock (as discussed
in Section 2.7) or in shares of Series B1 Preferred Stock (as discussed in Section 2.7), within five Business Days
of the end of each fiscal quarter of the Corporation (currently March 31, June 30, September 30 and December 31, each, as applicable
a “Dividend Payable Date”), for so long as the Series B1 Preferred Stock remains outstanding. If the
Corporation is prohibited from paying the Accrued Dividends in cash (pursuant to the Senior Credit Agreement), or registered common
stock, the Accrued Dividends will be paid in kind in Series B1 Preferred Stock. 


2.3             
Cash Dividend Payments. All Dividends payable in cash hereunder shall be made in lawful
money of the United States of America to each Holder in whose name the Series B1 Preferred Stock is registered as set forth on
the books and records of the Corporation. Such payments shall be made by wire transfer of immediately available funds to the account
such Holder may from time to time designate by written notice to the Corporation or by Corporation cashier’s check, without
any deduction, withholding or offset for any reason whatsoever except to the extent required by law.


2.4             
Participation. Subject to the rights of the holders, if any, of any shares of the Series
A Convertible Preferred Stock or Series B Preferred Stock, the Holders shall, as holders of Series B1 Preferred Stock, be entitled
to such dividends paid and Distributions made to the holders of Common Stock to the same extent as if such Holders had converted
the Series B1 Preferred Stock into Common Stock (without regard to any limitations on conversion herein or elsewhere) and had held
such shares of Common Stock on the record date for such dividends and Distributions. Payments under the preceding sentence shall
be made concurrently with the dividend or Distribution to the holders of Common Stock. Following the occurrence of a Liquidation
Event (as hereinafter defined) and the payment in full to a Holder of its applicable Liquidation Preference, such Holder shall
cease to have any rights hereunder to participate in any future dividends or distributions made to the holders of Common Stock.
No Distributions shall be made with respect to the Common Stock until all past due, if any, and/or declared Dividends on the Series
B1 Preferred Stock have been paid or set aside for payment to the Holders. Notwithstanding the foregoing, the Holders shall have
no right of participation in connection with dividends or Distributions made to the Common Stock shareholders consisting solely
of shares of Common Stock. 



    	Vertex Energy: Series B1 Certificate of Designation
	 	13



     

    




2.5             
Non-Cash Distributions. Whenever a Distribution provided for in this Section 2
shall be payable in property other than cash, the value of such Distribution shall be deemed to be the fair market value of such
property as determined in good faith by the Board of Directors.


2.6             
Other Distributions. Subject to the terms of this Certificate of Designation, and to
the fullest extent permitted by the NRS, the Corporation shall be expressly permitted to redeem, repurchase or make distributions
on the shares of its capital stock in all circumstances other than where doing so would cause the Corporation to be unable to pay
its debts as they become due in the usual course of business or at any time that any amounts are outstanding and claimed under
the Senior Credit Agreement (unless consent to such redemption, repurchase or distribution is provided by the lenders thereunder).


2.7             
Stock Dividend Payments. In lieu of paying the Accrued Dividends in cash, at the option
of the Corporation, the Corporation may pay Accrued Dividends in shares of Common Stock of the Corporation (“Dividend
Shares”), provided that the Corporation shall not issue Dividend Shares to any Holder if such issuance would cause
the Holder to exceed the Maximum Percentage described in Section 4.1(e) below. The total Dividend Shares issuable in connection
with the payment by the Corporation of the Accrued Dividends in shares of Common Stock shall be equal to the total amount of Accrued
Dividends which the Corporation has decided to pay in shares of Common Stock divided by the Dividend Shares Conversion Price on
the applicable Dividend Payable Date. The payment of any Dividends in shares of Common Stock shall be subject in all cases to the
Dividend Conversion Limitation. Notwithstanding any other provision of this Section, the Dividend Shares may only be issued in
the event the Dividend Shares are covered by a valid and effective registration under the Securities Act that permits the unrestricted
resale of the Dividend Shares at the time of receipt and any time thereafter. In the event the Corporation is prohibited from paying
the Accrued Dividends in cash or shares of Common Stock, the Accrued Dividends shall be paid in shares of Series B1 Preferred Stock
(“PIK Shares”) equal to the total amount of Accrued Dividends which the Corporation is paying in shares
of Series B1 Preferred Stock divided by the Original Issue Price. At the time any payment of Accrued Dividends is required in the
form of additional shares of Series B1 Preferred Stock, if the number of authorized but unissued shares of Series B1 Preferred
Stock shall not be sufficient to effect such payment in additional shares of Series B1 Preferred Stock, in addition to such other
remedies as shall be available to the holders of Series B1 Preferred Stock, the Corporation will take such corporate action as
may, in the opinion of its counsel, be necessary to increase its authorized but unissued shares of Series B1 Preferred Stock to
such number of shares as shall be sufficient for such purpose including, without limitation, engaging in commercially reasonable
best efforts to obtain the requisite stockholder approval of any necessary amendment to the Certificate of Incorporation or this
Certificate of Designation.

3.                 
Liquidation Rights. 


3.1             
Liquidation Preference. In
the event of any liquidation, dissolution or winding up of the Corporation, either voluntary or involuntary (each a “Liquidation
Event”), the holders of Series B1 Preferred Stock shall be entitled to receive pari passu with any Distribution of
any of the assets of the Corporation to the holders of the Corporation’s Series B Preferred Stock and prior and in preference
to any Distribution of any of the assets of the Corporation to the holders of the Corporation’s securities other than Senior
Securities by reason of their ownership of such stock, but not prior to any holders of the Corporation’s Senior Securities,
which holders of the Senior Securities shall have priority to the Distribution of any assets of the Corporation, an amount per
share for each share of Series B1 Preferred Stock held by them equal to the sum of (i) the Liquidation Preference, and (ii) all
Accrued Dividends and all declared but unpaid dividends on such share of Series B1 Preferred Stock. If upon the liquidation, dissolution
or winding up of the Corporation, the assets of the Corporation legally available for distribution to the holders of the Series
B1 Preferred Stock (i.e., after payment of the Corporation’s liabilities and payment to any holders of the Corporation’s
Senior Securities and pari passu with the holders of the Series B Preferred Stock) are insufficient to permit the payment to such
holders of the full amounts specified in this Section then the entire assets of the Corporation legally available for distribution
shall be distributed with equal priority and pro rata among the holders of the Series B Preferred Stock and Series B1 Preferred
Stock in proportion to the full amounts they would otherwise be entitled to receive pursuant to this Section and applicable law.


3.2             
Remaining Assets. After the payment to the Holders of Series B Preferred Stock and
Series B1 Preferred Stock of the full preferential amounts specified above, the entire remaining assets of the Corporation legally
available for distribution by the Corporation shall be distributed with equal priority and pro rata among the holders of Common
Stock and other junior securities in proportion to the number of shares of Common Stock and junior securities held by them. 


3.3             
Reorganization. For purposes of this Section 3, a Liquidation Event shall be
deemed to occur upon (a) a sale, lease, exclusive license or other conveyance of all or substantially all of the assets of the
Corporation or (b) any transaction or series of related transactions (including, without limitation, any reorganization, share
exchange, consolidation or merger of the Corporation with or into any other entity but excluding any sale of capital stock by the
Corporation for capital raising purposes) (i) in which the holders of the Corporation’s outstanding capital stock immediately
before the first such transaction do not, immediately after any other such transaction, retain stock or other equity interests
representing at least 50% of the voting power of the surviving entity of such transaction or (ii) in which at least 50% of the
Corporation’s outstanding capital stock (calculated on an as-converted to Common Stock basis) is transferred; provided any
transaction or event approved by a Majority In Interest shall not be considered a Liquidation Event hereunder 


3.4             
Valuation of Non-Cash Consideration. If any assets of the Corporation distributed to
stockholders in connection with any liquidation, dissolution, or winding up of the Corporation are other than cash, then the value
of such assets shall be their fair market value as determined in good faith by the Board of Directors. In the event of a merger
or other acquisition of the Corporation by another entity, the Distribution date shall be deemed to be the date such transaction
closes.

4.                 
Conversion. The holders of the Series B1 Preferred
Stock shall have conversion rights as follows (the “Conversion Rights”): 


4.1             
Holder Conversion. 


(a)               
Each share of Series B1 Preferred Stock and all Accrued Dividends shall be convertible, at
the option of the holder thereof (a “Holder Conversion”), at any time following the Closing Date, at
the office of the Corporation or any Transfer Agent for the Series B1 Preferred Stock, into that number of fully-paid, nonassessable
shares of Common Stock determined by dividing (i) the Original Issue Price for the Series B1 Preferred Stock by the Conversion
Price and (ii) the total Accrued Dividends desired to be converted divided by the Dividend Shares Conversion Price calculated as
of the date of the Notice of Conversion, subject to the Dividend Conversion Limitation (such shares of Common Stock issuable upon
a Conversion, the “Holder Conversion Shares”). In order to effectuate the Holder Conversion under this
Section 4.1, the Holder must provide the Corporation a written notice of conversion in the form of Exhibit A hereto
(the “Notice of Conversion”). The Notice of Conversion must be dated no earlier than three Business Days
from the date the Notice of Conversion is actually received by the Corporation.


(b)              
Mechanics of Conversion. In order to effect an Conversion, a holder shall fax or email
a copy of the fully executed Notice of Conversion to the Corporation (or in the discretion of the Corporation, with notice to the
Holder, the Transfer Agent)(Attention: Chris Carlson, Corporate Secretary, 1331 Gemini Street, Suite 250, Houston, Texas 77058,
Fax: , Email: chrisc@vertexenergy.com,
with a copy to (which shall not constitute notice) The Loev Law Firm, PC, Attn: David M. Loev, Esq., 6300 West Loop South, Suite
280, Bellaire, Texas 77401, Fax: (713) 524-4122, Email: dloev@loevlaw.com).
Upon receipt by the Corporation (or the Transfer Agent) of a facsimile or emailed copy of a Notice of Conversion from a Holder,
the Corporation (or the Transfer Agent) shall promptly send, via facsimile or email, a confirmation to such Holder stating that
the Notice of Conversion has been received, the date upon which the Corporation (or the Transfer Agent) expects to deliver the
Common Stock issuable upon such conversion and the name and telephone number of a contact person at the Corporation (or the Transfer
Agent) regarding the Conversion. The holder shall surrender, or cause to be surrendered, the Preferred Stock Certificates being
converted, duly endorsed, to the Corporation (or the Transfer Agent) at the address listed above within three Business Days of
delivering the fully executed Notice of Conversion. The Corporation (or the Transfer Agent) shall not be obligated to issue shares
of Common Stock upon a Conversion unless either (x) the Preferred Stock Certificates; or (y) the Lost Certificate Materials described
in Section 12, below have been previously received by the Corporation or its Transfer Agent. In the event the Holder has
lost or misplaced the certificates evidencing the Preferred Stock, the Holder shall be required to provide the Corporation or the
Corporation’s Transfer Agent (as applicable) with whatever documentation and fees each may require to re-issue the Preferred
Stock Certificates and shall be required to provide such re-issued Preferred Stock Certificates to the Corporation (or the Transfer
Agent) within three Business Days of delivering the Notice of Conversion. Unless the Holder Conversion Shares are covered by a
valid and effective registration under the Securities Act or the Notice of Conversion provided by the Holder includes a valid opinion
from an attorney stating that such shares of Common Stock issuable in connection with the Notice of Conversion can be issued free
of restrictive legend, which shall be determined by the Corporation (or the Transfer Agent) in its sole discretion, such shares
shall be issued as Restricted Shares. 



    	Vertex Energy: Series B1 Certificate of Designation
	 	16



     

    




(c)               
Delivery of Common Stock upon Conversion. Upon the receipt of a Notice of Conversion,
the Corporation (itself, or through its Transfer Agent) shall, no later than the third Business Day following the date of such
receipt (subject to the surrender of the Preferred Stock Certificates by the holder within the period described in Section 4.1(b)
or, in the case of lost, stolen or destroyed certificates, after provision of the Lost Certificate Materials) (the “Delivery
Period”), issue and deliver (i.e., deposit with a nationally recognized overnight courier service postage prepaid)
to the Holder or its nominee (x) a certificate representing the Holder Conversion Shares and (y) a certificate representing
the number of shares of Series B1 Preferred Stock not being converted, if any. Notwithstanding the foregoing, if the Corporation’s
Transfer Agent is participating in the Depository Trust Corporation (“DTC”) Fast Automated Securities
Transfer program, and so long as the certificates therefor do not bear a legend and the holder thereof is not then required to
return such certificate for the placement of a legend thereon, the Corporation shall cause its Transfer Agent to promptly electronically
transmit the Common Stock issuable upon conversion to the Holder by crediting the account of the Holder or its nominee with DTC
through its Deposit Withdrawal Agent Commission system (“DTC Transfer”). If the aforementioned conditions
to a DTC Transfer are not satisfied, the Corporation shall deliver as provided above to the Holder physical certificates representing
the Common Stock issuable upon Holder Conversion. Further, a Holder may instruct the Corporation to deliver to the Holder physical
certificates representing the Common Stock issuable upon conversion in lieu of delivering such shares by way of DTC Transfer. 


(d)              
Failure to Provide Preferred Stock Certificates. In the event the Holder provides the
Corporation with a Notice of Conversion, but fails to provide the Corporation with the Preferred Stock Certificates or the Lost
Certificate Materials (as defined in Section 12 below), by the end of the Delivery Period, the Notice of Conversion shall
be considered void and the Corporation shall not be required to comply with such Notice of Conversion. Provided that if the Notice
of Conversion only relates to the conversion of Accrued Dividends, the Holder shall not be required to provide the Corporation
any Preferred Stock Certificates. 


(e)               
Beneficial Ownership Limitation for Holder Conversions and Voting. No Holder Conversion
shall result in the conversion of more than that number of shares of Series B1 Preferred Stock, if any, such that, upon such Holder
Conversion, the aggregate beneficial ownership of the Corporation’s Common Stock (calculated pursuant to Rule 13d-3 of the
Exchange Act) of such Holder and all persons affiliated with such Holder as described in Rule 13d-3 is more than 9.999% of the
Corporation’s Common Stock then outstanding (the “Maximum Percentage”). In the event any Holder
Conversion would result in the issuance of shares of Common Stock to any Holder in excess of the Maximum Percentage, only that
number of shares of Series B1 Convertible Preferred Stock which when Converted would not result in such Holder exceeding the Maximum
Percentage shall be subject to such applicable Holder Conversion, if any, and Holder shall continue to hold any remaining shares
of Series B1 Preferred Stock, the conversion of which would result in Holder exceeding the Maximum Percentage. The Corporation’s
Transfer Agent shall be authorized to promptly disclose the total outstanding shares of Common Stock of the Corporation to the
Holder from time to time at the request of the Holder in order for the Holder to determine its compliance with the Maximum Percentage.
The provisions of this Section 4.1(e) shall not be construed and implemented in a manner otherwise than in strict conformity
with the terms of this Section 4.1(e) to correct this Section (or any portion hereof) which may be defective or inconsistent
with the intended Maximum Percentage herein contained or to make changes or supplements necessary or desirable to properly give
effect to such limitation. The Corporation shall not be required to verify or investigate or confirm whether any Holder Conversion
would exceed the Maximum Percentage, and instead the Corporation shall be able to rely on any Notice of Holder Conversion as prima
facie evidence of, and as a representation by, the applicable Holder, that such applicable conversion described in the Notice of
Holder Conversion would not result in a violation of the Maximum Percentage Additionally, in no event shall any Holder have the
right pursuant to Section 6.1 below, to vote, on any matter presented to the shareholders of the Corporation for their action
or consideration at any meeting of shareholders of the Corporation (or by written consent of shareholders in lieu of meeting),
a number of voting shares in excess of the Maximum Percentage.

4.2             
Automatic Conversion. 


(a)               
At such time, if ever, following the earlier of (i) six months from the Closing Date or (ii)
the effective date of a valid and effective registration statement under the Securities Act covering the resale of the Common Stock
issuable upon conversion of the Series B1 Preferred Stock, each share of Series B1 Preferred Stock, shall automatically and without
any required action by any Holder, be converted into that number of fully-paid, non-assessable shares of Common Stock as determined
by dividing the Original Issue Price by the Conversion Price, provided, that the Closing Sales Price of the Corporation’s
Common Stock is equal to at least $3.90 per share of Common Stock as adjusted for Recapitalizations (the “Trading Price”)
for a period of at least 20 consecutive Trading Days (an “Automatic Conversion” and together with a Holder
Conversion, each a “Conversion”).


(b)              
Following an Automatic Conversion, the Corporation shall within two Business Days, deliver
notice to each Holder that an Automatic Conversion has occurred, at the address of each Holder which the Corporation then has on
record (an “Automatic Conversion Notice”); provided, that the Corporation is not required to receive
any confirmation that such Automatic Conversion Notice was received by a Holder, but instead assuming such Automatic Conversion
Notice was sent to the address which the Corporation then has on record for such Holder, the Automatic Conversion Notice shall
be treated as received by the Holder for all purposes on the third Business Day following the date such notice was sent by the
Corporation (the “Automatic Conversion Notice Receipt Date”). Within three Business Days following the
Automatic Conversion Notice Receipt Date, the Corporation shall pay each Holder the total amount of Accrued Dividends owed on such
Series B1 Preferred Stock, if any (the “Automatic Conversion Dividends”) in cash (subject to the terms
of the Senior Credit Agreement) or at the option of the Corporation, in shares of Common Stock equal to the total Accrued Dividends
divided by the Dividend Shares Conversion Price calculated on the applicable Automatic Conversion Notice Receipt Date, subject
to the Dividend Conversion Limitation, and issue to each Holder all shares of Common Stock which such Holder is due in connection
with the Automatic Conversion (the “Automatic Conversion Shares”, and together with the Holder Conversion
Shares, the “Shares”) and promptly deliver such Automatic Conversion Shares (and if applicable, cash
in an amount equal to the Accrued Dividends) to the address of Holder which the Corporation then has on record (a “Delivery”).
The Automatic Conversion Shares issuable in connection with an Automatic Conversion shall be fully-paid, non-assessable shares
of Common Stock. Unless the Automatic Conversion Shares are covered by a valid and effective registration under the Securities
Act or the Holder provides a valid opinion from an attorney stating that such Automatic Conversion Shares can be issued free of
restrictive legend, which shall be determined by the Corporation in its sole discretion, prior to the issuance date of such Automatic
Conversion Shares, such Automatic Conversion Shares shall be issued as Restricted Shares. 



    	Vertex Energy: Series B1 Certificate of Designation
	 	18



     

    




(c)               
The issuance and Delivery by the Corporation of the Automatic Conversion Shares (and if applicable,
the cash Accrued Dividends) shall fully discharge the Corporation from any and all further obligations under or in connection with
the Series B1 Preferred Stock and shall automatically, and without any required action by the Corporation or the Holder, result
in the cancellation, termination and invalidation of any outstanding Series B1 Preferred Stock and Preferred Stock Certificates
held by Holder or his, her or its assigns and shall upon the payment of the Automatic Conversion Dividends, fully discharge any
and all requirement for the Corporation to pay Dividends on such Series B1 Preferred Stock shares converted, which Series B1 Preferred
Stock converted shall cease accruing Dividends upon an Automatic Conversion. 


(d)              
Without limiting the obligation of each Holder set forth herein (including in the subsequent
clause (e)), the Corporation and/or the Corporation’s Transfer Agent shall be authorized to take whatever action necessary,
if any, following the issuance and Delivery of the Automatic Conversion Shares to reflect the cancellation of the Series B1 Preferred
Stock subject to the Automatic Conversion, which shall not require the approval and/or consent of any Holder (a “Cancellation”).



(e)               
Notwithstanding the above, each Holder, by accepting such Preferred Stock Certificates hereby
covenants that it will, whenever and as reasonably requested by the Corporation and the Transfer Agent, at the Corporation’s
sole cost and expense, do, execute, acknowledge and deliver any and all such other and further acts, deeds, assignments, transfers,
conveyances, confirmations, powers of attorney and any instruments of further assurance, approvals and consents as the Corporation
or the Transfer Agent may reasonably require in order to complete, insure and perfect the Cancellation, if such may be reasonably
required by the Corporation and/or the Corporation’s Transfer Agent.


(f)               
In the event that the Delivery of any Automatic Conversion Shares (or any cash Accrued Dividends)
is unsuccessful and/or any Holder fails to accept such Automatic Conversion Shares (or applicable cash Accrued Dividends), such
Automatic Conversion Shares (and if applicable, cash Accrued Dividends) shall be held by the Corporation and/or the Transfer Agent
in trust (without accruing interest) and shall be released to such Holder upon reasonable evidence to the Corporation or the Transfer
Agent that such Holder is the legal owner of such Automatic Conversion Shares, provided that the Holder’s failure to accept
such Automatic Conversion Shares, cash Accrued Dividends and/or the Corporation’s inability to Deliver such shares or dividends
shall in no event effect the validity of the Cancellation.



    	Vertex Energy: Series B1 Certificate of Designation
	 	19



     

    




(g)              
The Automatic Conversion Right shall supersede and take priority over the Holder’s Optional
Conversion Right in the event that there are any conflicts between such rights.


(h)              
The Maximum Percentage ownership limitation described in Section 4.1(e) above shall
not apply to an Automatic Conversion, provided that the Automatic Conversion Shares, including any shares issuable in consideration
for Accrued Dividends shall be subject to the Share Cap. In the event any Automatic Conversion would result, if Converted in full,
in the Corporation exceeding the Share Cap, the maximum number of shares of Common Stock allowable under the Share Cap shall be
issued pro rata to each Holder and, and subject to the terms of the Senior Credit Agreement, the remaining Series B1 Preferred
Stock shares and/or Accrued Dividends shall be immediately redeemed by the Corporation as if such remaining portion of Series B1
Preferred Stock and/or Accrued Dividends was subject to a Mandatory Redemption on such Automatic Conversion Notice Receipt Date
(as provided in Section 8 hereof, substituting the Automatic Conversion Notice Receipt Date for the Required Redemption
Date in Section 8). 


4.3             
Fractional Shares. If any Conversion of Series B1 Preferred Stock would result in the
issuance of a fractional share of Common Stock (aggregating all shares of Series B1 Preferred Stock being converted pursuant to
a given Notice of Conversion), then subject to the terms of the Senior Credit Agreement, such fractional share shall be payable
in cash based upon the market value of the Common Stock on the trading day immediately prior to the date of conversion (as determined
in good faith by the Board of Directors) and the number of shares of Common Stock issuable upon conversion of the Series B1 Preferred
Stock shall be the next lower whole number of shares. If the Corporation elects not to, or is unable to, make such a cash payment,
the Holder shall be entitled to receive, in lieu of the final fraction of a share, one whole share of Common Stock. 


4.4             
Taxes. The Corporation shall not be required to pay any tax which may be payable
in respect to any transfer involved in the issue and delivery of shares of Common Stock upon Conversion in a name other than that
in which the shares of the Series B1 Preferred Stock so converted were registered, and no such issue or delivery shall be made
unless and until the person requesting such issue or delivery has paid to the Corporation the amount of any such tax, or has established,
to the satisfaction of the Corporation, that such tax has been paid. The Corporation shall withhold from any payment due whatsoever
in connection with the Series B1 Preferred Stock any and all required withholdings and/or taxes the Corporation, in its sole discretion
deems reasonable or necessary, absent an opinion from Holder’s accountant or legal counsel, acceptable to the Corporation
in its sole determination, that such withholdings and/or taxes are not required to be withheld by the Corporation.


4.5             
No Impairment. The Corporation will not through any reorganization, transfer of assets,
merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance
of any of the terms to be observed or performed hereunder by the Corporation but will at all times in good faith assist in the
carrying out of all the provisions of this Section 4 and in the taking of all such action as may be necessary or appropriate
in order to protect the Conversion Rights of the holders of Series B1 Preferred Stock against impairment. Notwithstanding the foregoing,
nothing in this Section shall prohibit the Corporation from amending its Articles of Incorporation with the requisite consent of
its stockholders and the Board of Directors, provided that such amendment will not prohibit the Corporation from having sufficient
authorized shares of Common Stock to permit conversion hereunder. 



    	Vertex Energy: Series B1 Certificate of Designation
	 	20



     

    




4.6             
Reservation of Stock Issuable Upon Conversion. The Corporation shall at all times reserve
and keep available out of its authorized but unissued shares of Common Stock solely for the purpose of effecting the conversion
of the shares of the Series B1 Preferred Stock, such number of its shares of Common Stock as shall from time to time be sufficient
to effect the conversion of all then outstanding shares of the Series B1 Preferred Stock; and if at any time the number of authorized
but unissued shares of Common Stock shall not be sufficient to effect the conversion of all then outstanding shares of the Series
B1 Preferred Stock, the Corporation will use its commercially reasonable efforts to take such corporate action as may, in the opinion
of its counsel, be necessary to increase its authorized but unissued shares of Common Stock to such number of shares as shall be
sufficient for such purpose. 


4.7             
Cap on Shares of Common Stock. Notwithstanding anything herein to the contrary, the
maximum number of shares of Common Stock to be issued in connection with the Conversion of all of the outstanding shares of Series
B1 Preferred Stock shares (and upon conversion or exercise of any other securities required to be aggregated with the Series B1
Preferred Stock pursuant to the applicable rules and requirements of the NASDAQ Capital Market), or otherwise as provided herein,
shall not exceed such number of shares of Common Stock that would violate applicable listing rules of the NASDAQ Capital Market
in the event the Corporation’s stockholders do not approve the issuance of the Common Stock issuable in connection with a
Conversion (and upon conversion or exercise of any other securities required to be aggregated with the Series B1 Preferred Stock
pursuant to the applicable rules and requirements of the NASDAQ Capital Market), or otherwise as provided herein (the “Share
Cap”). In the event the number of shares of Common Stock to be issued hereunder (and upon conversion or exercise
of any other securities required to be aggregated with the Series B1 Preferred Stock pursuant to the applicable rules and requirements
of the NASDAQ Capital Market) in connection with a Conversion or otherwise, exceeds the Share Cap, then subject to the terms of
the Senior Credit Agreement, the Corporation shall instead (i) immediately redeem such portion of Series B1 Preferred Stock, the
conversion of which would exceed the Share Cap, in cash as if such applicable Series B1 Preferred Stock shares were subject to
a Mandatory Redemption (as provided in Section 8 hereof); and (ii) pay any Accrued Dividends and future Dividends in cash,
or shall otherwise first obtain the approval of the stockholders of the Corporation under applicable rules and requirements of
the NASDAQ Capital Market prior to issuing such shares of Common Stock in excess of the Share Cap.


5.                 
Adjustments for Recapitalizations.


5.1             
Equitable Adjustments for Recapitalizations. (a) The Liquidation Preference and the
Original Issue Price (each, as and if applicable) (the “Preferred Stock Adjustable Provisions”); (b)
the Conversion Price, Dividend Shares Conversion Price and Trading Price (as and if applicable) (the “Common Stock
Adjustable Provisions”), and (c) any and all other terms, conditions, amounts and provisions of this Designation
which (i) pursuant to the terms of this Designation provide for equitable adjustment in the event of a Recapitalization (the “Other
Equitable Adjustable Provisions”); or (ii) the Board of Directors of the Corporation determines in their reasonable
good faith judgment is required to be equitably adjusted in connection with any Recapitalizations, shall each be subject to equitable
adjustment as provided in Sections 5.2 through 5.3, below, as determined by the Board of Directors in their sole
and reasonable discretion.



    	Vertex Energy: Series B1 Certificate of Designation
	 	21



     

    




5.2             
Adjustments for Subdivisions or Combinations of Common Stock. In the event the outstanding
shares of Common Stock shall be subdivided (by stock split, by payment of a stock dividend or otherwise), into a greater number
of shares of Common Stock, without a corresponding subdivision of the Series B1 Preferred Stock, the applicable Common Stock Adjustable
Provisions and the Other Equitable Adjustable Provisions (if any) in effect immediately prior to such subdivision shall, concurrently
with the effectiveness of such subdivision, be proportionately and equitably adjusted. In the event the outstanding shares of Common
Stock shall be combined (by reclassification or otherwise) into a lesser number of shares of Common Stock, without a corresponding
combination of the Series B1 Preferred Stock, the Common Stock Adjustable Provisions and the Other Equitable Adjustable Provisions
(if any) in effect immediately prior to such combination shall, concurrently with the effectiveness of such combination, be proportionately
and equitably adjusted. 


5.3             
Adjustments for Subdivisions or Combinations of Series B1 Preferred Stock. In the event
the outstanding shares of Series B1 Preferred Stock shall be subdivided (by stock split, by payment of a stock dividend or otherwise),
into a greater number of shares of Series B1 Preferred Stock, the applicable Preferred Stock Adjustable Provisions, Common Stock
Adjustable Provisions and the Other Equitable Adjustable Provisions (if any) in effect immediately prior to such subdivision shall,
concurrently with the effectiveness of such subdivision, be proportionately adjusted. In the event the outstanding shares of Series
B1 Preferred Stock shall be combined (by reclassification or otherwise) into a lesser number of shares of Series B1 Preferred Stock,
the applicable Preferred Stock Adjustable Provisions, Common Stock Adjustable Provisions and the Other Equitable Adjustable Provisions
(if any) in effect immediately prior to such combination shall, concurrently with the effectiveness of such combination, be proportionately
adjusted. 


5.4             
Adjustments for Reclassification, Exchange and Substitution. 


(a)Except to the
extent such Recapitalization Event is subject to Sections 5.1 through 5.3, above (the “Recapitalization
and Adjustment Rights”), and/or Section 3 (“Liquidation Rights”), if at any time
or from time to time after the Closing Date there shall occur any capital reorganization, recapitalization, reclassification, share
exchange, restructuring, consolidation, combination or merger involving the Corporation in which the Common Stock (but not the
Series B1 Preferred Stock) is converted into or exchanged for shares of stock or other securities or property (including cash)
of the Corporation or otherwise (other than a transaction covered by the Recapitalization and Adjustment Rights or Liquidation
Rights) (each a “Recapitalization Event”), provision shall be made so that each Series B1 Preferred Holder
shall thereafter be entitled to receive upon conversion of the shares of Series B1 Preferred Stock held by such Series B1 Preferred
Holder the kind and number of shares of stock or other securities or property (including cash or any combination thereof) of the
Corporation or otherwise, to which a Common Stock shareholder holding the number of shares of Common Stock into which the shares
of Series B1 Preferred Stock held by such Series B1 Preferred Holder are convertible immediately prior to such reorganization,
recapitalization, reclassification, consolidation or merger (without regard for the Maximum Percentage) would have been entitled
upon such event.

	 	22



     

    




(b)In the event
that the holders of Common Stock have the opportunity to elect the form of consideration to be received in the business combination,
then the Corporation shall make adequate provision whereby the holders of Series B1 Preferred Stock shall have the opportunity
to determine the form of consideration into which all of the Series B1 Preferred Stock, treated as a single class, shall be convertible
from and after the effective date of such business combination. If such opportunity is granted, such determination shall be based
on the determination at a meeting duly called or via a written consent to action of a Majority In Interest, shall be subject to
any limitations to which all holders of Common Stock are subject, such as pro rata reductions applicable to any portion of the
consideration payable in such business combination, and shall be conducted in such a manner as to be completed by the date which
is the earliest of (1) the deadline for elections to be made by holders of Common Stock and (2) two Business Days prior to the
anticipated effective date of the business combination. Further, the Corporation shall not effect any such consolidation, merger
or sale, unless prior to the consummation thereof, the successor entity (if other than the Corporation) resulting from consolidation
or merger or the entity purchasing such assets assumes by written instrument, the obligation to deliver to each such holder such
shares of stock, securities or assets as, in accordance with the foregoing provisions, such holder may be entitled to acquire.


(c)If a conversion
of Series B1 Preferred Stock is to be made in connection with a transaction contemplated by this Section 5.3 or a similar
transaction affecting the Corporation (other than a tender or exchange offer), the conversion of any shares of Series B1 Preferred
Stock may, at the election of the Holder thereof, be conditioned upon the consummation of such transaction, in which case such
conversion shall not be deemed to be effective until such transaction has been consummated. In connection with any tender or exchange
offer for shares of Common Stock, Holders of Series B1 Preferred Stock shall have the right to tender (or submit for exchange)
shares of Series B1 Preferred Stock in such a manner so as to preserve the status of such shares as Series B1 Preferred Stock until
immediately prior to such time as shares of Common Stock are to be purchased (or exchanged) pursuant to such offer, at which time
that portion of the shares of Series B1 Preferred Stock so tendered which is convertible into the number of shares of Common Stock
to be purchased (or exchanged) pursuant to such offer shall be deemed converted into the appropriate number of shares of Common
Stock. Any shares of Series B1 Preferred Stock not so converted shall be returned to the Holder as Series B1 Preferred Stock.


(d)None of the
foregoing provisions shall affect the right of a Holder of shares of Series B1 Preferred Stock to convert such Holder’s shares
of Series B1 Preferred Stock into shares of Common Stock prior to the effective date of such business combination, subject to the
terms of this Designation.


(e)In the event
of any Recapitalization Event falling under this Section 5.3, in such case, appropriate adjustment shall be made in the
application of the provisions of this Section 5.3 with respect to the rights and interests of the Series B1 Preferred Holders
after such events to the end that the provisions of this Section 5.3 (including, but not limited to, adjustment of the Conversion
Price in respect of any shares of Series B1 Preferred Stock then in effect and the number of shares issuable upon conversion of
all such shares of Series B1 Preferred Stock) shall be applicable after that event as nearly reasonably as may be. The Corporation
may not become a party to any such transaction unless its terms are consistent with the preceding requirements and such transaction
is otherwise effected in accordance with this Designation.

5.5             
Certificate as to Adjustments. Upon the occurrence of each adjustment or readjustment
pursuant to this Section 5, the Corporation at its expense shall promptly compute such adjustment or readjustment in accordance
with the terms hereof and furnish to each holder of Series B1 Preferred Stock a certificate setting forth such adjustment or readjustment
and showing in detail the facts upon which such adjustment or readjustment is based. The Corporation shall, upon the reasonable
written request at any time of any holder of Series B1 Preferred Stock, furnish or cause to be furnished to such holder a like
certificate setting forth (i) such adjustments and readjustments, (ii) the Conversion Price at the time in effect, and (iii) the
number of shares of Common Stock and the amount, if any, of other property which at the time would be received upon the conversion
of the Series B1 Preferred Stock. 


6.                 
Voting. 


6.1             
Restricted Class Voting. In addition to any class or series voting rights provided
to the holders of Series B1 Preferred Stock herein or required by law, on any matter presented to the shareholders of the Corporation
for their action or consideration at any meeting of shareholders of the Corporation (or by written consent of shareholders in lieu
of meeting), each holder of outstanding shares of Series B1 Preferred Stock shall be entitled to cast the number of votes equal
to the number of whole shares of Common Stock into which the shares of Series B1 Preferred Stock held by such holder are convertible
as of the record date for determining shareholders entitled to vote on such matter, subject in all cases to the Maximum Percentage
(i.e., in no event shall any Holder have the right to vote more voting shares in connection with the terms of this Section 6.1
than as equals its individual Maximum Percentage (when aggregated with all other voting shares beneficially owned by such Holder
as of such applicable record date)), and shall be entitled, notwithstanding any provision hereof, to notice of any shareholders’
meeting in accordance with the bylaws of the Corporation. Fractional votes shall not, however, be permitted and any fractional
voting rights available on an as-converted to Common Stock basis (after aggregating all fractional shares into which shares of
Series B1 Preferred Stock held by each holder could be converted) shall be rounded to the nearest whole share (with one-half being
rounded upward). Except as provided by law or by the other provisions of the Articles of Incorporation or this Designation, holders
of Series B1 Preferred Stock shall vote together with the holders of Common Stock
as a single class. In the event any Holder’s voting rights under this Section 6.1 are limited by the Maximum Percentage,
the total number of voting shares eligible to be voted on the applicable matter shall similarly be decreased. For the sake of clarity,
the purpose of this Section 6.1 is to limit the maximum voting rights of the Series B1 Preferred Stock shares held by any
individual Holder, to the lesser of (a) 9.99% of the Corporation’s Common Stock then outstanding; and (b) such number of
voting shares of the Corporation, if any, that, when added together with the other voting securities of the Corporation beneficially
owned (as calculated pursuant to Rule 13d-3 of the Exchange Act) by such Holder, totals 9.99% of the Corporation’s then outstanding
Common Stock.


6.2             
No Series Voting. Other than as provided herein or required by law, there shall be
no series voting.

of redemption, or increase the authorized number of shares of any additional class or series of capital stock unless the same ranks
junior to (and not pari passu with) the Series B1 Preferred Stock with respect to the distribution of assets on the liquidation,
dissolution or winding up of the Corporation, the payment of dividends and rights of redemption, in each such case, other than
issuances of (or in connection with issuances of) shares of Series B1 Preferred Stock pursuant to the Purchase Agreement and PIK
Shares;


(d)              
Issue, incur or obligate itself to issue or incur any indebtedness that is convertible into,
or exchangeable for, any equity security of the Corporation or instruments derivative of any equity security of the Corporation;


(e)               
Grant any rights to require a mandatory repurchase, retirement or redemption by the Corporation
of any of the Corporation’s equity securities or instruments derivative of its equity securities on or prior to the Required
Redemption Date, or issue, incur or obligate the Corporation to issue or incur, any indebtedness with a maturity date on or prior

(i)                
Alter or change the rights, preferences or privileges of the shares of Series B1 Preferred
Stock so as to affect adversely the shares of such series; or 


(j)                
Amend or waive any provision of the Corporation’s Articles of Incorporation or Bylaws
relative to the Series B1 Preferred Stock so as to affect adversely the shares of Series B1 Preferred Stock in any material respect
as compared to holders of other series of shares. 


8.                 
Redemption Rights. 


8.1             
Optional Corporation Redemption. Subject to the terms of the Senior Credit Agreement,
the Corporation shall have the option, exercisable from time to time after the Corporation Redemption Triggering Date, to redeem
all or any portion of the outstanding shares of Series B1 Preferred Stock (a “Corporation Redemption”)
which have not been previously Converted into Common Stock (as provided above in Section 4) (the “Corporation
Redemption Rights”), by paying each applicable Holder, an amount equal to (a) 110% of the Original Issue Price multiplied
by the number of Series B1 Preferred Stock shares held by each applicable Holder, subject to the Corporation Redemption; plus (b)
the Accrued Dividends (the “Corporation Redemption Amount”). 


(a)               
In the event the Corporation exercises its Corporation Redemption Rights, it shall redeem
and repurchase Series B1 Preferred Stock pari passu with the Series B Preferred Stock and pro rata between all Holders based on
the Pro Rata Amount.


(b)              
To exercise the Corporation Redemption Right, the Corporation shall deliver to each Holder
an irrevocable written notice (a “Corporation Redemption Notice”), indicating the date the Corporation
intends to pay the Corporation Redemption Amount (as applicable, the “Corporation Redemption Date”),
which date may not be less than ten days nor more than 20 days from the date the Corporation Redemption Notice is delivered to
a Holder. In the event the applicable aggregate Corporation Redemption Amount is not paid to the Holders on the applicable Corporation
Redemption Date, the Corporation Redemption Notice shall be considered void and of no force or effect. 


(c)               
Notwithstanding the foregoing, the Series B1 Preferred Stock may not be redeemed unless and
until all amounts outstanding and claimed under the Senior Credit Agreement have been paid in full in cash.


8.2             
Mandatory Corporation Redemption. Notwithstanding the Corporation Redemption Rights
set forth in Section 8.1, above, the Corporation shall, subject to the terms of the Senior Credit Agreement, be required
to redeem all then outstanding shares of Series B1 Preferred Stock within two Business Days of the Required Redemption Date (“Mandatory
Redemption” and together with a Corporation Redemption, a “Redemption”). A Mandatory Redemption
shall be effected by the Corporation, within two Business Days of the Required Redemption Date (the “Post-Redemption
Triggering Period”), by paying each Holder an amount in cash equal to (a) the Original Issue Price multiplied by
the number of Series B1 Preferred Stock shares held by each applicable Holder, subject to the Mandatory Redemption; plus (b) the
Accrued Dividends (the “Mandatory Redemption Amount” and together with the Corporation Redemption Amount,
each as applicable, a “Redemption Amount”) and promptly delivering such Mandatory Redemption Amount to
the address of Holder which the Corporation then has on record. The date of such Redemption Delivery (as defined below) shall be
defined herein as the “Mandatory Redemption Date”). The Holders shall be prohibited from Converting the
Series B1 Preferred Stock during the Post-Redemption Triggering Period, unless the Corporation shall allow such Conversion, at
the Corporation’s sole option and its sole discretion.

8.3             
Effect of Redemption. The payment by the Corporation to each Holder (at each such Holder’s
address of record) (or if the Holder fails to deliver the Preferred Stock Certificates and/or Lost Certificate Materials required
to be delivered as discussed below in connection with such Redemption, upon the Corporation setting aside such Redemption Amount
in trust for the benefit of the Holder) of the Corporation Redemption Amount or Mandatory Redemption Amount (as applicable, a “Redemption
Delivery”) in connection with a Corporation Redemption or Mandatory Redemption, as applicable, and effective as of
the Corporation Redemption Date or the Mandatory Redemption Date, as applicable, shall fully discharge the Corporation from any
and all further obligations under the Series B1 Preferred Stock shares redeemed and shall automatically, and without any required
action by the Corporation or the Holder or his, her or its assigns (including the requirement that the Holder provide the Corporation
or the Corporation’s Transfer Agent the Preferred Stock Certificates relating to such Corporation Redemption), result in
the cancellation, termination and invalidation of any outstanding Series B1 Preferred Stock and related Preferred Stock Certificates
held by a Holder which are subject to a Corporation Redemption or Mandatory Redemption, as applicable and shall upon the payment
of the applicable Redemption Amount, fully discharge any and all requirement for the Corporation to pay further Dividends, and
which Series B1 Preferred Stock shall cease accruing Dividends upon a Redemption. 


8.4             
Further Actions Following Redemption. Without limiting the obligation of each Holder
set forth herein (including in the subsequent Section 8.5), the Corporation and/or the Corporation’s Transfer Agent shall
be authorized to take whatever action necessary, if any, following the payment of the Corporation Redemption Amount or Mandatory
Redemption Amount, to reflect the cancellation of the Series B1 Preferred Stock subject to the applicable Redemption, which shall
not require the approval and/or consent of any Holder, and provided that by agreeing to the terms and conditions of this Designation
and the acceptance of the Series B1 Preferred Stock, each Holder hereby agrees to release the Corporation and the Corporation’s
Transfer Agent from any and all liability whatsoever in connection with the cancellation of the Series B1 Preferred Stock subject
to and following a Corporation Redemption and/or a Mandatory Redemption, regardless of the return to the Corporation or the Transfer
Agent of any Preferred Stock Certificates evidencing such Series B1 Preferred Stock subject to the Corporation Redemption and/or
Mandatory Redemption, as applicable, which as stated above, shall be automatically cancelled upon the payment of the Corporation
Redemption Amount and Mandatory Redemption Amount, as applicable to the Holder, or if the provisions of Section 8.6 apply
and the Holder fails to deliver the Preferred Stock Certificates and/or Lost Certificate Materials, upon the Corporation setting
aside such Redemption Amount in trust for the benefit of the Holder (a “Redemption Cancellation”). 



    	Vertex Energy: Series B1 Certificate of Designation
	 	27



     

    




8.5             
Further Redemption Assurances. Notwithstanding the above, each Holder, by accepting
such Preferred Stock Certificates hereby covenants that it will (a) deliver to the Corporation or the Corporation’s Transfer
Agent, promptly upon the receipt of any Corporation Redemption Notice, but in any case prior to the applicable Corporation Redemption
Date, and/or promptly upon the occurrence of the Required Redemption Date, the applicable Preferred Stock Certificates relating
to the Corporation Redemption and Mandatory Redemption, as applicable (or Lost Certificate Materials associated therewith); and
(b) whenever and as reasonably requested by the Corporation and the Corporation’s Transfer Agent, at the Corporation’s
sole cost and expense, do, execute, acknowledge and deliver any and all such other and further acts, deeds, assignments, transfers,
conveyances, confirmations, powers of attorney and any instruments of further assurance, approvals and consents as the Corporation
or the Transfer Agent may reasonably require in order to complete, insure and perfect a Redemption Cancellation, if such may be
reasonably required by the Corporation and/or the Corporation’s Transfer Agent.


8.6             
Additional Redemption Procedures. In the event that (a) Redemption Delivery is
unsuccessful notwithstanding the fact that the Corporation has mailed such applicable Corporation Redemption Amount and/or Mandatory
Redemption Amount to the correct address of the Holder as set forth in the records of the Corporation; or (b) any Holder fails
to timely deliver to the Corporation for cancellation the Preferred Stock Certificates evidencing the Series B1 Preferred Stock
subject to such Corporation Redemption and/or Mandatory Redemption, or Lost Certificate Materials associated therewith, and the
Corporation therefore refrains from completing a Redemption Delivery, such Corporation Redemption Amount and/or Mandatory Redemption
Amount shall be held by the Corporation in trust and such Redemption Amount shall be released to such Holder upon reasonable evidence
to the Corporation or the Transfer Agent that such Holder is (y) the legal owner of such Corporation Redemption Amount and/or Mandatory
Redemption Amount and/or (z) the delivery to the Corporation or its Transfer Agent of the applicable Preferred Stock Certificates,
as applicable, or Lost Certificate Materials, provided that the Holder’s failure to accept such Corporation Redemption Amount
and/or Mandatory Redemption Amount, the Corporation’s inability to pay any Holder its applicable Redemption Amount, and/or
the Holder’s failure to deliver the Preferred Stock Certificates or Lost Certificate Materials, under either of such circumstances
shall in no event effect the validity of the Corporation Redemption Cancellation, Redemption Cancellation, or the consequences
of a Corporation Redemption Delivery or Mandatory Redemption Delivery as described in Section 8.1 and Section 8.2
hereof. Furthermore, the Holder shall be due no interest on the Corporation Redemption Amount and/or Mandatory Redemption Amount
while being held by the Corporation in trust and any and all interest, if any, which shall accrue on such amount shall be the sole
property of the Corporation.


8.7             
Further Holder Redemption Assurances. Notwithstanding the above, each Holder, by accepting
such Preferred Stock Certificates will whenever and as reasonably requested by the Corporation and the Corporation’s Transfer
Agent, at its sole cost and expense, do, execute, acknowledge and deliver any and all such other and further acts, deeds, assignments,
transfers, conveyances, confirmations, powers of attorney and any instruments of further assurance, approvals and consents as the
Corporation or the Transfer Agent may reasonably require in order to complete, insure and perfect the cancellation of such Holder’s
shares in the event of a Corporation Redemption and/or Mandatory Redemption, if such may be reasonably required by the Corporation
and/or the Corporation’s Transfer Agent.

Effect of All Redemptions. The Series B1 Preferred Stock subject to a Corporation Redemption
and/or Mandatory Redemption shall cease accruing any Dividends and shall have all Conversion rights immediately terminate effective
as of the Corporation Redemption Date or the Mandatory Redemption Date, unless otherwise agreed in the sole discretion of the Corporation.



8.9             
Redemption Failure. In the event the Corporation is prohibited from completing a Mandatory
Redemption by the Senior Credit Agreement, the Series B1 Preferred Stock shall remain outstanding until such time as the Corporation
is no longer prohibited by the Senior Credit Agreement from completing a Mandatory Redemption and at that time the Corporation
shall immediately redeem the Series B1 Preferred Stock pursuant to this Section 8. During the period the Corporation is
prohibited from completing a Mandatory Redemption by the Senior Credit Agreement, the term “Dividend Rate” shall mean
10%.

selling stockholders may pledge or grant a security interest in some or all of the 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.


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.


The
selling stockholders will sell their shares of common stock subject to the following:


·  all
or a portion of the shares of common stock beneficially owned by the selling stockholders or their perspective pledgees, donees,
transferees or successors in interest, may be sold on the OTC Market, any national securities exchange or quotation service on
which the shares of our common stock may be listed or quoted at the time of sale, in the over-the counter market, in privately
negotiated transactions, through the writing of options, whether such options are listed on an options exchange or otherwise, short
sales or in a combination of such transactions;


·   each
sale may be made at market price prevailing at the time of such sale, at negotiated prices, at fixed prices or at carrying prices
determined at the time of sale;


·     some
or all of the shares of common stock may be sold through one or more broker-dealers or agents and may involve crosses, block transactions
or hedging transactions. The selling stockholders may enter into hedging transactions with broker-dealers or agents, which may
in turn engage in short sales of the 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 to close out short positions or loan or pledge shares
of common stock to broker-dealers or agents that in turn may sell such shares; and


·     in
connection with such sales through one or more broker-dealers or agents, such broker-dealers or agents may receive compensation
in the form of discounts, concessions or commissions from the selling stockholders and may receive commissions from the purchasers
of the shares of common stock for whom they act as broker-dealer or agent or to whom they sell as principal (which discounts, concessions
or commissions as to particular broker-dealers or agents may be in excess of those customary in the types of transaction involved).
Any broker-dealer or agent participating in any such sale may be deemed to be an “underwriter” within the meaning of
the Securities Act and will be required to deliver a copy of this prospectus to any person who purchases any share of common stock
from or through such broker-dealer or agent. We have been advised that, as of the date hereof, none of the selling stockholders
have made any arrangements with any broker-dealer or agent for the sale of their shares of common stock.


The
selling stockholder 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 profits realized by the selling stockholders and
any commissions 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. In addition, any shares of common stock covered by this prospectus which qualify for sale
pursuant to Rule 144 may be sold under Rule 144 rather than pursuant to this prospectus. A selling stockholder may also transfer,
devise or gift the shares of common stock by other means not covered in this prospectus in which case the transferee, devisee
or giftee will be the selling stockholder under this prospectus.

If
required at the time a particular offering of the shares of common stock is made, a prospectus supplement or, if appropriate, a
post-effective amendment to the shelf registration statements of which this prospectus is a part, 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-deals or agents, any discounts, commissions or concessions allowed or reallowed 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 shelf 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 Exchange
Act and the rules and regulations thereunder, including, without limitation, 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. 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 or entity to engage in market-making activities with respect to the shares
of common stock.


We will bear all expenses of the registration
of the shares of common stock including, without limitation, Securities and Exchange Commission filing fees and expenses of compliance
with the state securities of “blue sky” laws. The selling stockholders will pay all underwriting discounts and selling
commissions and expenses, brokerage fees and transfer taxes, as well as the fees and disbursements of counsel to and experts for
the selling stockholders, if any. We will indemnify the selling stockholders against liabilities, including some liabilities under
the Securities Act, in accordance with the registration rights agreement or the selling stockholder will be entitled to contribution.
We will 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 stockholders for use in this prospectus, in accordance with
the related securities purchase agreement or will be entitled to contribution. Once sold under this 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.

Dear Sirs or Madams:


As an inducement
to Craig-Hallum Capital Group LLC (the “Agent”) to act as placement agent in connection with a private
placement (the “Offering”) of preferred stock (the “Preferred Stock”) and warrants
to purchase common stock of Vertex Energy, Inc., a Nevada corporation, and
any successor (by merger or otherwise) thereto (the “Company”), the undersigned hereby agrees that without,
in each case, the prior written consent of the Agent during the period specified in the second succeeding paragraph (the “Lock-Up
Period”), the undersigned will not (1) offer, pledge, announce the intention to sell, 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, make
any short sale or otherwise transfer or dispose of, directly or indirectly, any shares of the Preferred Stock or common stock of
the Company (the “Common Stock”) or any securities convertible into, exercisable or exchangeable for
or that represent the right to receive the Preferred Stock or Common Stock (including, without limitation, the Preferred Stock
or Common Stock which may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of
the Securities and Exchange Commission and securities which may be issued upon exercise of a stock option or warrant) whether now
owned or hereafter acquired (the “Undersigned’s Securities”) or (2) enter into any swap or other
agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Undersigned’s Securities,
whether any such transaction described in clause (1) or clause (2) above is to be settled by delivery of the Preferred Stock or
Common Stock or such other securities, in cash or otherwise. The foregoing restriction is expressly agreed to preclude the undersigned
from engaging in any hedging or other transaction which is designed to or which reasonably could be expected to lead to or result
in a sale or disposition of the Undersigned’s Securities even if such securities would be disposed of by someone other than
the undersigned. Such prohibited hedging or other transactions would include, without limitation, any short sale or any purchase,
sale or grant of any right (including, without limitation, any put or call option) with respect to any of the Undersigned’s
Securities or with respect to any security that includes, relates to or derives any significant part of its value from such Securities.


In addition, the
undersigned agrees that, without the prior written consent of the Agent, it
will not, during the Lock-Up Period, make any demand for or exercise any right with respect to, the registration of any of the
Preferred Stock or Common Stock or any security convertible into or exercisable or exchangeable for the Preferred Stock or Common
Stock.


The initial Lock-Up
Period will commence on the date of this Agreement and continue to and include the date that is 90 days after the date on which
the resale registration statement registering the securities sold in the Offering becomes effective.


Notwithstanding the
foregoing, the undersigned may transfer the Undersigned’s Securities (i) as a bona fide gift or gifts and (ii) to
any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned; provided, in
each case, that (x) such transfer shall not involve a disposition for value, (y) the transferee agrees in writing with the Agent
to be bound by the terms of this Lock-Up Agreement and (z) no filing by any party under Section 16(a) of the Securities Exchange
Act of 1934, as amended (the “Exchange Act”), shall be required or shall be made voluntarily in connection
with such transfer. For purposes of this Agreement, “immediate family” shall mean any relationship by blood, marriage
or adoption, nor more remote than first cousin.


In addition, the
foregoing restrictions shall not apply to (i) the exercise of stock options granted pursuant to the Company’s equity
incentive plans; provided that it shall apply to any of the Undersigned’s Securities issued upon such exercise or
(ii) the establishment of any contract, instruction or plan (a “Plan”) that satisfies all of the
requirements of Rule 10b5-1(c)(1)(i)(B) under the Exchange Act; provided that no sales of the Undersigned’s Securities
shall be made pursuant to such a Plan prior to the expiration of the Lock-Up Period, and such a Plan may only be established if
no public announcement of the establishment or existence thereof and no filing with the Securities and Exchange Commission or
other regulatory authority in respect thereof or transactions thereunder or contemplated thereby, by the undersigned, the Company
or any other person, shall be required, and no such announcement or filing is made voluntarily, by the undersigned, the Company
or any other person, prior to the expiration of the Lock-Up Period.
