require the registration of any such securities under the Securities Act, or (ii) any applicable shareholder approval provisions
of any Trading Market on which any of the securities of the Company are listed or designated.

(aa)           Solvency.
Based on the consolidated financial condition of the Company as of the Closing Date, after giving effect to the receipt by the
Company of the proceeds from the sale of the Shares hereunder: (i) the fair saleable value of the Company’s assets exceeds
the amount that will be required to be paid on or in respect of the Company’s existing debts and other liabilities (including
known contingent liabilities, but excluding milestones and contingent payments that may be payable pursuant to material agreement
to which the Company is a party and which have been filed as exhibits to the SEC Reports) as they mature, (ii) the Company’s
assets do not constitute unreasonably small capital to carry on its business as now conducted and as proposed to be conducted including
its capital needs taking into account the particular capital requirements of the business conducted by the Company, consolidated
and projected capital requirements and capital availability thereof, and (iii) the current cash flow of the Company, together with
the proceeds the Company would receive, were it to liquidate all of its assets, after taking into account all anticipated uses
of the cash, would be sufficient to pay all amounts on or in respect of its liabilities when such amounts are required to be paid.
The Company does not intend to incur debts beyond its ability to pay such debts as they mature (taking into account the timing
and amounts of cash to be payable on or in respect of its debt). The Company has no knowledge of any facts or circumstances which
lead it to believe that it will file for reorganization or liquidation under the bankruptcy or reorganization laws of any jurisdiction
within one year from the Closing Date. Neither the Company nor any Subsidiary has any Indebtedness, except as disclosed in the
SEC Reports. For the purposes of this Agreement, “Indebtedness” means (x) any liabilities for borrowed money
or amounts owed in excess of $50,000 (other than trade accounts payable incurred in the ordinary course of business), (y) all guaranties,
endorsements and other contingent obligations in respect of indebtedness of others, whether or not the same are or should be reflected
in the Company’s consolidated balance sheet (or the notes thereto), except guaranties by endorsement of negotiable instruments
for deposit or collection or similar transactions in the ordinary course of business; and (z) the present value of any lease payments
in excess of $50,000 due under leases required to be capitalized in accordance with GAAP. Neither the Company nor any Subsidiary
is in default with respect to any Indebtedness.

income and all foreign income and franchise tax returns, reports and declarations required by any jurisdiction to which it is subject,
(ii) has paid all taxes and other governmental assessments and charges that are material in amount, shown or determined to be due
on such returns, reports and declarations, except those being contested in good faith, with respect to which adequate reserves
have been set aside on the books of the Company and (iii) has set aside on its books provision reasonably adequate for the payment
of all material taxes for periods subsequent to the periods to which such returns, reports or declarations apply. There are no
unpaid taxes in any material amount claimed to be due by the taxing authority of any jurisdiction, and the officers of the Company
or of any Subsidiary know of no basis for any such claim.

General Solicitation. Neither the Company nor any person acting on behalf of the Company has offered or sold any of the Shares

unlawful payment to foreign or domestic government officials or employees or to any foreign or domestic political parties or campaigns
from corporate funds, (iii) failed to disclose fully any contribution made by the Company or any Subsidiary (or made by any person

not constitute a breach of any of the Transaction Documents.

3.2           Representations
and Warranties of the Purchasers. Each Purchaser, for itself and for no other Purchaser, hereby represents and warrants as
of the date hereof and as of the Closing Date to the Company as follows (unless as of a specific date therein):

 

(a)           Organization;
Authority. Such Purchaser is either an individual or an entity duly incorporated or formed, validly existing and in good standing
under the laws of the jurisdiction of its incorporation or formation with full right, corporate, partnership, limited liability
company or similar power and authority to enter into and to consummate the transactions contemplated by the Transaction Documents
and otherwise to carry out its obligations hereunder and thereunder. The execution and delivery of the Transaction Documents and
performance by such Purchaser of the transactions contemplated by the Transaction Documents have been duly authorized by all necessary
corporate, partnership, limited liability company or similar action, as applicable, on the part of such Purchaser. Each Transaction
Document to which it is a party has been duly executed by such Purchaser, and when delivered by such Purchaser in accordance with
the terms hereof, will constitute the valid and legally binding obligation of such Purchaser, enforceable against it in accordance
with its terms, except: (i) as limited by general equitable principles and applicable bankruptcy, insolvency, reorganization, moratorium
and other laws of general application affecting enforcement of creditors’ rights generally, (ii) as limited by laws relating
to the availability of specific performance, injunctive relief or other equitable remedies and (iii) insofar as indemnification
and contribution provisions may be limited by applicable law.

 

    	 	19	 

     

    

 

(b)           Own
Account. Such Purchaser understands that the Shares are “restricted securities” and have not been registered under
the Securities Act or any applicable state securities law and is acquiring the Shares as principal for its own account and not
with a view to or for distributing or reselling such Shares or any part thereof in violation of the Securities Act or any applicable
state securities law, has no present intention of distributing any of such Shares in violation of the Securities Act or any applicable
state securities law and has no direct or indirect arrangement or understandings with any other persons to distribute or regarding
the distribution of such Shares in violation of the Securities Act or any applicable state securities law (this representation
and warranty not limiting such Purchaser’s right to sell the Shares pursuant to the Registration Statement or otherwise in
compliance with applicable federal and state securities laws). Such Purchaser is acquiring the Shares hereunder in the ordinary
course of its business.

 

(c)           Purchaser
Status. At the time such Purchaser was offered the Shares, it was, and as of the date hereof it is either: (i) an “accredited
investor” as defined in Rule 501(a)(1), (a)(2), (a)(3), (a)(5), (a)(6), (a)(7) or (a)(8) under the Securities Act or (ii)
a “qualified institutional buyer” as defined in Rule 144A(a) under the Securities Act. Such Purchaser is not required
to be registered as a broker-dealer under Section 15 of the Exchange Act.

 

(d)           Experience
of Such Purchaser. Such Purchaser, either alone or together with its representatives, has such knowledge, sophistication and
experience in business and financial matters so as to be capable of evaluating the merits and risks of the prospective investment
in the Shares, and has so evaluated the merits and risks of such investment. Such Purchaser is able to bear the economic risk of
an investment in the Shares and, at the present time, is able to afford a complete loss of such investment.

 

(e)           General
Solicitation. Such Purchaser is not purchasing the Shares as a result of any advertisement, article, notice or other communication
regarding the Shares published in any newspaper, magazine or similar media or broadcast over television or radio or presented at
any seminar or any other general solicitation or general advertisement.

 

(f)           Access
to Information. Such Purchaser acknowledges that it has had the opportunity to review the Transaction Documents (including
all exhibits and schedules thereto) and the SEC Reports and has been afforded (i) the opportunity to ask such questions as it has
deemed necessary of, and to receive answers from, representatives of the Company concerning the terms and conditions of the offering
of the Shares and the merits and risks of investing in the Shares; (ii) access to information about the Company and its financial
condition, results of operations, business, properties, management and prospects sufficient to enable it to evaluate its investment;
and (iii) the opportunity to obtain such additional information that the Company possesses or can acquire without unreasonable
effort or expense that is necessary to make an informed investment decision with respect to the investment.

 

(g)           Brokers
and Finders. No Person will have, as a result of the transactions contemplated by this Agreement, any valid right, interest
or claim against or upon the Company or any Purchaser for any commission, fee or other compensation pursuant to any agreement,
arrangement or understanding entered into by or on behalf of the Purchaser.

 

    	 	20	 

     

    

 

(h)           Limited
Ownership. The purchase by such Purchaser of the Shares issuable to it at the Closing will not result in such Purchaser (individually
or together with other Person with whom such Purchaser has identified, or will have identified, itself as part of a “group”
in a public filing made with the Commission involving the Company’s securities) acquiring, or obtaining the right to acquire,
in excess of 19.99% 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. Such Purchaser does not presently intend to, alone or together with others, make
a public filing with the Commission to disclose that it has (or that it together with such other Persons 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 19.99% 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.

 

(i)           Independent
Investment Decision. Such Purchaser has independently evaluated the merits of its decision to purchase Shares pursuant to the
Transaction Documents, and such Purchaser confirms that it has not relied on the advice of any other Purchaser’s business
and/or legal counsel in making such decision. Such Purchaser understands that nothing in this Agreement or any other materials
presented by or on behalf of the Company to the Purchaser in connection with the purchase of the Shares constitutes legal, tax
or investment advice. Such 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 the Shares.

 

(j)           No
Governmental Review. Such Purchaser understands that no United States federal or state agency or any other government or governmental
agency has passed on or made any recommendation or endorsement of the Shares or the fairness or suitability of the investment in
the Shares nor have such authorities passed upon or endorsed the merits of the offering of the Shares.

 

(k)           Reliance
on Exemptions. Such Purchaser understands that the Shares being offered and sold to it in reliance on specific exemptions from
the registration requirements of United States federal and state securities laws and that the Company is relying in part upon the
truth and accuracy of, and such Purchaser’s compliance with, the representations, warranties, agreements, acknowledgements
and understandings of such Purchaser set forth herein in order to determine the availability of such exemptions and the eligibility
of such Purchaser to acquire the Shares.

 

(l)           Certain
Transactions and Confidentiality. Other than consummating the transactions contemplated hereunder, such Purchaser has not directly
or indirectly, nor has any Person acting on behalf of or pursuant to any understanding with such Purchaser, executed any purchases
or sales, including Short Sales, of the securities of the Company during the period commencing as of 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 and ending immediately prior to the execution hereof. 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 Shares covered by this
Agreement. Other than to other Persons party to this Agreement and its legal and accounting advisers, 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.

 

    	 	21	 

     

    

 

The Company acknowledges and agrees that
the representations contained in Section 3.2 shall not modify, amend or affect such Purchaser’s right to rely on the
Company’s representations and warranties contained in this Agreement or any representations and warranties contained in any
other Transaction Document or any other document or instrument executed and/or delivered in connection with this Agreement or the
consummation of the transaction contemplated hereby.

 

ARTICLE IV.

OTHER AGREEMENTS OF THE PARTIES

 

4.1           Transfer
Restrictions.

 

(a)           The
Shares may only be disposed of in compliance with state and federal securities laws. In connection with any transfer of Shares
other than pursuant to an effective registration statement or Rule 144, to the Company or to an Affiliate of a Purchaser or in
connection with a pledge as contemplated in Section 4.1(b), the Company may require the transferor thereof to provide to
the Company an opinion of counsel selected by the transferor and reasonably acceptable to the Company, the fees and expenses of
which shall be borne by the Company, to the effect that such transfer does not require registration of such transferred Shares
under the Securities Act. As a condition of transfer, any such transferee shall agree in writing to be bound by the terms of this
Agreement and the Registration Rights Agreement and shall have the rights and obligations of a Purchaser under this Agreement and
the Registration Rights Agreement.

 

(b)           The
Purchasers agree to the imprinting, so long as is required by this Section 4.1, of a legend on any of the Shares in the
following form:

 

[NEITHER] THIS SECURITY [NOR
THE SECURITIES INTO WHICH THIS SECURITY IS EXERCISABLE] HAS [NOT] BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR
THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED
(THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT
UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS
OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL TO THE
TRANSFEROR TO SUCH EFFECT, THE SUBSTANCE OF WHICH SHALL BE REASONABLY ACCEPTABLE TO THE COMPANY. THIS SECURITY [AND THE SECURITIES
ISSUABLE UPON EXERCISE OF THIS SECURITY] MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT WITH A REGISTERED BROKER-DEALER
OR OTHER LOAN WITH A FINANCIAL INSTITUTION THAT IS AN “ACCREDITED INVESTOR” AS DEFINED IN RULE 501(a) UNDER THE SECURITIES
ACT OR OTHER LOAN SECURED BY SUCH SECURITIES.

 

    	 	22	 

     

    

 

The Company
acknowledges and agrees that a Purchaser may from time to time pledge pursuant to a bona fide margin agreement with a registered
broker-dealer or grant a security interest in some or all of the Shares to a financial institution that is an “accredited
investor” as defined in Rule 501(a) under the Securities Act and who agrees to be bound by the provisions of this Agreement
and the Registration Rights Agreement and, if required under the terms of such arrangement, such Purchaser may transfer pledged
or secured Shares to the pledgees or secured parties. Such a pledge or transfer would not be subject to approval of the Company
and no legal opinion of legal counsel of the pledgee, secured party or pledgor shall be required in connection therewith. Further,
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 Shares may reasonably request in connection with a pledge or transfer
of the Shares, including, if the Shares are subject to registration pursuant to the Registration Rights Agreement, the preparation
and filing of any required prospectus supplement under Rule 424(b)(3) under the Securities Act or other applicable provision of
the Securities Act to appropriately amend the list of Selling Stockholders (as defined in the Registration Rights Agreement) thereunder.

 

(c)           Certificates
evidencing the Shares shall not contain any legend (including the legend set forth in Section 4.1(b) hereof): (i) while
a registration statement (including the Registration Statement) covering the resale of such security is effective under the Securities
Act, (ii) following any sale of such Shares pursuant to Rule 144, (iii) if such Shares are eligible for sale under 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 Commission). The Company shall cause its counsel to issue a legal opinion to the Transfer
Agent promptly if required by the Transfer Agent to effect the removal of the legend hereunder. The Company agrees that following
such time as such legend is no longer required under this Section 4.1(c), it will, no later than three Trading Days following
the delivery by a Purchaser to the Company or the Transfer Agent of a certificate representing Shares, as applicable, issued with
a restrictive legend (such third Trading Day, the “Legend Removal Date”), deliver or cause to be delivered to
such Purchaser a certificate representing such shares that is free from all restrictive and other legends. The Company may not
make any notation on its records or give instructions to the Transfer Agent that enlarge the restrictions on transfer set forth
in this Article IV. Certificates for Shares subject to legend removal hereunder shall be transmitted by the Transfer Agent
to the Purchaser by crediting the account of the Purchaser’s prime broker with the Depository Trust Company System as directed
by such Purchaser.

 

(d)           In
addition to such Purchaser’s other available remedies, the Company shall pay to a Purchaser, in cash, as partial liquidated
damages and not as a penalty, for each $2,000 of Shares (based on the VWAP of the Common Stock on the date such Shares are submitted
to the Transfer Agent) delivered for removal of the restrictive legend and subject to Section 4.1(c), $5 per Trading Day
for each Trading Day after the 2nd Trading Day following the Legend Removal Date until such certificate is delivered
without a legend. Nothing herein shall limit such Purchaser’s right to pursue actual damages for the Company’s failure
to deliver certificates representing any Shares as required by the Transaction Documents, and such Purchaser shall have the right
to pursue all remedies available to it at law or in equity including, without limitation, a decree of specific performance and/or
injunctive relief.

 

    	 	23	 

     

    

 

(e)           While
a Registration Statement remains effective, each Purchaser hereunder may sell the shares in accordance with the plan of distribution
contained in such Registration Statement and if it does so it will comply therewith and with the related prospectus delivery requirements
unless an exemption therefrom is available. Each Purchaser, severally and not jointly with the other Purchasers, agrees that if
it is notified by the Company at any time after the date any legend is removed pursuant to the Registration Rights Agreement that
no Registration Statement is effective or that the prospectus included in any such Registration Statement no longer complies with
the requirements of Section 10 of the Securities Act, the Purchaser will refrain from selling such Shares until such time as the
Purchaser is notified by the Company that a Registration Statement is effective or such prospectus is compliant with Section 10
of the Exchange Act, unless such Purchaser is able to, and does, sell such Shares pursuant to an available exemption from the registration
requirements of Section 5 of the Securities Act. Each Purchaser further acknowledges that the removal of the restrictive legend
from certificates representing Shares as set forth in this Section 4.1 is predicated upon the Company’s reliance upon
the Purchaser’s acknowledgements and agreements contained in this paragraph.

 

4.2           Furnishing
of Information; Public Information. Until the earliest of the time that no Purchaser owns Shares, the Company covenants to
maintain the registration of the Common Stock under Section 12(b) or 12(g) of the Exchange Act and to timely file (or obtain extensions
in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date
hereof pursuant to the Exchange Act even if the Company is not then subject to the reporting requirements of the Exchange Act.

 

4.3           Integration.
The Company shall not sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined
in Section 2 of the Securities Act) that would be integrated with the offer or sale of the Shares in a manner that would require
the registration under the Securities Act of the sale of the Shares or that would be integrated with the offer or sale of the Shares
for purposes of the rules and regulations of any Trading Market such that it would require shareholder approval prior to the closing
of such other transaction unless shareholder approval is obtained before the closing of such subsequent transaction.

 

4.4           Securities
Laws Disclosure; Publicity. The Company shall by 9:00 a.m. (New York City time) on the Trading Day immediately following the
date hereof, (a) issue a press release disclosing the material terms of the transactions contemplated hereby, and (b) file a Current
Report on Form 8-K, including the Transaction Documents as exhibits thereto, with the Commission. From and after the issuance of
such press release, the Company represents to the Purchasers that it shall have publicly disclosed all material, non-public information
delivered to any of the Purchasers by the Company or any of its Subsidiaries, or any of their respective officers, directors, employees
or agents in connection with the transactions contemplated by the Transaction Documents. Notwithstanding the foregoing, the Company
shall not publicly disclose the name of any Purchaser, or include the name of any Purchaser in any filing with the Commission or
any regulatory agency or Trading Market, without the prior written consent of such Purchaser, except: (a) as required by federal
securities law in connection with (i) any registration statement contemplated by the Registration Rights Agreement and (ii) the
filing of final Transaction Documents with the Commission and (b) to the extent such disclosure is required by law or Trading Market
regulations, in which case the Company shall provide the Purchasers with prior notice of such disclosure permitted under this clause
(b).

 

    	 	24	 

     

    

 

4.5           Shareholder
Rights Plan. No claim will be made or enforced by the Company or, with the consent of the Company, any other Person, that any
Purchaser is an “Acquiring Person” under any control share acquisition, business combination, poison pill (including
any distribution under a rights agreement) or similar anti-takeover plan or arrangement in effect or hereafter adopted by the Company,
or that any Purchaser could be deemed to trigger the provisions of any such plan or arrangement, by virtue of receiving Shares
under the Transaction Documents or under any other agreement between the Company and the Purchasers.

 

4.6           Non-Public
Information. Except with respect to the material terms and conditions of the transactions contemplated by the Transaction Documents,
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 entered into a written agreement with the Company regarding the confidentiality and use of such information.
The Company understands and confirms that each Purchaser shall be relying on the foregoing covenant in effecting transactions in
securities of the Company.

 

4.7           Use of Proceeds.
The Company shall use the net proceeds from the sale of the Shares hereunder for working capital purposes and shall not use such
proceeds: (a) for the satisfaction of any portion of the Company’s debt (other than payment of trade payables in the ordinary
course of the Company’s business and prior practices), (b) for the redemption of any Common Stock or Common Stock Equivalents,
(c) to pay any dividends on any of the Company’s capital stock, (d) for the settlement of any outstanding litigation or (d)
in violation of FCPA or OFAC regulations.

 

4.8           Indemnification
of Purchasers. Subject to the provisions of this Section 4.8, the Company will indemnify and hold each Purchaser and
its directors, officers, shareholders, members, partners, employees, consultants and agents (and any other Persons with a functionally
equivalent role of a Person holding such titles notwithstanding a lack of such title or any other title), each Person who controls
such Purchaser (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors,
officers, shareholders, agents, members, partners, consultants or employees (and any other Persons with a functionally equivalent
role of a Person holding such titles notwithstanding a lack of such title or any other title) of such controlling persons (each,
a “Purchaser Party”) harmless from any and all losses, liabilities, obligations, claims, contingencies, damages,
costs and expenses, including all judgments, amounts paid in settlements, court costs and reasonable attorneys’ fees and
costs of investigation that any such Purchaser Party may suffer or incur as a result of or relating to (a) any breach of any of
the representations, warranties, covenants or agreements made by the Company in this Agreement or in the other Transaction Documents
or (b) any action instituted against the Purchaser Parties in any capacity, or any of them or their respective Affiliates, by any
stockholder of the Company who is not an Affiliate of such Purchaser Party, with respect to any of the transactions contemplated
by the Transaction Documents (unless such action is based upon a breach of such Purchaser Party’s representations, warranties
or covenants under the Transaction Documents or any agreements or understandings such Purchaser Party may have with any such stockholder
or any violations by such Purchaser Party of state or federal securities laws or any conduct by such Purchaser Party which constitutes
fraud, gross negligence, willful misconduct or malfeasance). If any action shall be brought against any Purchaser Party in respect
of which indemnity may be sought pursuant to this Agreement, such Purchaser Party shall promptly notify the Company in writing,
and the Company shall have the right to assume the defense thereof with counsel of its own choosing reasonably acceptable to the
Purchaser Party. Any Purchaser Party shall have the right to employ separate counsel in any such action and participate in the
defense thereof, but the fees and expenses of such counsel shall be at the expense of such Purchaser Party except to the extent
that (i) the employment thereof has been specifically authorized by the Company in writing, (ii) the Company has failed after a
reasonable period of time to assume such defense and to employ counsel or (iii) in such action there is, in the reasonable opinion
of counsel, a material conflict on any material issue between the position of the Company and the position of such Purchaser Party,
in which case the Company shall be responsible for the reasonable fees and expenses of no more than one such separate counsel.
The Company will not be liable to any Purchaser Party under this Agreement (y) for any settlement by a Purchaser Party effected
without the Company’s prior written consent, which shall not be unreasonably withheld or delayed; or (z) to the extent, but
only to the extent that a loss, claim, damage or liability is attributable to any Purchaser Party’s breach of any of the
representations, warranties, covenants or agreements made by such Purchaser Party in this Agreement or in the other Transaction
Documents. The indemnification required by this Section 4.8 shall be made by periodic payments of the amount thereof during
the course of the investigation or defense, as and when bills are received or are incurred. The indemnity agreements contained
herein shall be in addition to any cause of action or similar right of any Purchaser Party against the Company or others and any
liabilities the Company may be subject to pursuant to law.

 

    	 	25	 

     

    

 

4.9           Equal Treatment
of Purchasers. No consideration (including any modification of any Transaction Document) 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 Shares or otherwise.

 

4.10           Certain
Transactions and Confidentiality. 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 (other than the purchases of shares pursuant to this Agreement) during the
period commencing with the execution of this Agreement and ending at such time that the transactions contemplated by this Agreement
are first publicly announced pursuant to the initial press release as described in Section 4.4.  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 pursuant to the initial press release as described in Section 4.4, such Purchaser will
maintain the confidentiality of the existence and terms of this transaction and the information included in the Transaction Documents
and the Disclosure Schedules. 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 pursuant to the initial press release as described in Section 4.4, (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
pursuant to the initial press release as described in Section 4.4 and (iii) no Purchaser shall have any duty of confidentiality
to the Company or its Subsidiaries after the issuance of the initial press release as described in Section 4.4.  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 covenant 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
Shares covered by this Agreement.

 

    	 	26	 

     

    

 

4.11           Form D;
Blue Sky Filings. The Company agrees to timely file a Form D with respect to the Shares as required under Regulation D and
to provide a copy thereof, promptly upon request of any Purchaser. The Company shall take such action as the Company shall reasonably
determine is necessary in order to obtain an exemption for, or to qualify the Shares for, sale to the Purchasers at the Closing
under applicable securities or “Blue Sky” laws of the states of the United States, and shall provide evidence of such
actions promptly upon request of any Purchaser.

5.5           Amendments;
Waivers. No provision of this Agreement may be waived, modified, supplemented or amended except in a written instrument signed,
in the case of an amendment, by the Company and the Purchasers holding at least two-thirds in interest of the Shares then outstanding
or, in the case of a waiver, by the party against whom enforcement of any such waived provision is sought. No waiver of any default
with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future
or a waiver of any subsequent default or a waiver of any other provision, condition or requirement hereof, nor shall any delay
or omission of any party to exercise any right hereunder in any manner impair the exercise of any such right.

5.6           Headings.
The headings herein are for convenience only, do not constitute a part of this Agreement and shall not be deemed to limit or affect
any of the provisions hereof.

 

5.7           Successors
and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their successors and permitted
assigns. The Company may not assign this Agreement or any rights or obligations hereunder without the prior written consent of
each Purchaser (other than by merger). Any Purchaser may assign any or all of its rights under this Agreement to any Person to
whom such Purchaser assigns or transfers any Shares, provided that such transferee agrees in writing to be bound, with respect
to the transferred Shares, by the provisions of the Transaction Documents that apply to the “Purchasers.”

 

5.8           No Third-Party
Beneficiaries. This Agreement is intended for the benefit of the parties hereto and their respective successors and permitted
assigns and is not for the benefit of, nor may any provision hereof be enforced by, any other Person, except as otherwise set forth
in Section 4.8.

 

5.9           Governing
Law. All questions concerning the construction, validity, enforcement and interpretation of the Transaction Documents shall
be governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the
principles of conflicts of law thereof. Each party agrees that all legal proceedings concerning the interpretations, enforcement
and defense of the transactions contemplated by this Agreement and any other Transaction Documents (whether brought against a party
hereto or its respective affiliates, directors, officers, shareholders, partners, members, employees or agents) shall be commenced
exclusively in the state and federal courts sitting in the City of New York. Each party hereby irrevocably submits to the exclusive
jurisdiction of the state and federal courts sitting in the City of New York, Borough of Manhattan for the adjudication of any
dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein (including with respect
to the enforcement of any of the Transaction Documents), and hereby irrevocably waives, and agrees not to assert in any suit, action
or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding
is improper or is an inconvenient venue for such proceeding. Each party hereby irrevocably waives personal service of process and
consents to process being served in any such suit, action or proceeding by mailing a copy thereof via registered or certified mail
or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Agreement
and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein
shall be deemed to limit in any way any right to serve process in any other manner permitted by law. If either party shall commence
an action, suit or proceeding to enforce any provisions of the Transaction Documents, then, in addition to the obligations of the
Company under Section 4.8, the prevailing party in such action, suit or proceeding shall be reimbursed by the other party
for its reasonable attorneys’ fees and other costs and expenses incurred with the investigation, preparation and prosecution
of such action or proceeding.

 

5.10           Survival.
The representations and warranties contained herein shall survive the Closing and the delivery of the Shares.

 

5.11           Execution.
This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered one and the same
agreement and shall become effective when counterparts have been signed by each party and delivered to each other party, it being
understood that the parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission
or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and binding obligation of the
party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or “.pdf”
signature page were an original thereof.

 

    	 	28	 

     

    

 

5.12           Severability.
If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, illegal,
void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full
force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall use their commercially
reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated
by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the parties that
they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be
hereafter declared invalid, illegal, void or unenforceable.

 

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

 

5.14           Replacement
of Shares. If any certificate or instrument evidencing any Shares is mutilated, lost, stolen or destroyed, the Company shall
issue or cause to be issued in exchange and substitution for and upon cancellation thereof (in the case of mutilation), or in lieu
of and substitution therefor, a new certificate or instrument, but only upon receipt of evidence reasonably satisfactory to the
Company of such loss, theft or destruction. The applicant for a new certificate or instrument under such circumstances shall also
pay any reasonable third-party costs (including customary indemnity) associated with the issuance of such replacement Shares.

 

5.15           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 any
Transaction Document to a number of shares or a price per share shall be deemed to be amended to appropriately account for such
event.

 

5.16           Remedies.
In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, each of
the Purchasers and the Company will be entitled to specific performance under the Transaction Documents. The parties agree that
monetary damages may not be adequate compensation for any loss incurred by reason of any breach of obligations contained in the
Transaction Documents and hereby agree to waive and not to assert in any action for specific performance of any such obligation
the defense that a remedy at law would be adequate.

 

5.17           Payment
Set Aside. To the extent that the Company makes a payment or payments to any Purchaser pursuant to any Transaction Document
or a Purchaser enforces or exercises its rights thereunder, and such payment or payments or the proceeds of such enforcement or
exercise or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside, recovered from,
disgorged by or are required to be refunded, repaid or otherwise restored to the Company, a trustee, receiver or any other Person
under any law (including, without limitation, any bankruptcy law, state or federal law, common law or equitable cause of action),
then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived
and continued in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred.

 

    	 	29	 

     

    

 

5.18           Independent
Nature of Purchasers’ Obligations and Rights. The obligations of each Purchaser under any Transaction Document are several
and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance
or non-performance of the obligations of any other Purchaser under any Transaction Document. Nothing contained herein or in any
other Transaction Document, and no action taken by any Purchaser pursuant hereto or thereto, 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 the Transaction
Documents. Each Purchaser shall be entitled to independently protect and enforce its rights, including, without limitation, the
rights arising out of this Agreement or out of the other Transaction Documents, and it shall not be necessary for any other Purchaser
to be joined as an additional party in any proceeding for such purpose. Each Purchaser has been represented by its own separate
legal counsel in its review and negotiation of the Transaction Documents. The Company has elected to provide all Purchasers with
the same terms and Transaction Documents for the convenience of the Company and not because it was required or requested to do
so by any of the Purchasers.

 

5.19           Saturdays,
Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right
required or granted herein shall not be a Business Day, then such action may be taken or such right may be exercised on the
next succeeding Business Day.

 

5.20           Construction.
The parties agree that each of them and/or their respective counsel have reviewed and had an opportunity to revise the Transaction
Documents and, therefore, the normal rule of construction to the effect that any ambiguities are to be resolved against the drafting
party shall not be employed in the interpretation of the Transaction Documents or any amendments thereto. In addition, each and
every reference to share prices and shares of Common Stock in any Transaction Document shall be subject to adjustment for reverse
and forward stock splits, stock dividends, stock combinations and other similar transactions of the Common Stock that occur after
the date of this Agreement.

 

5.21           WAIVER
OF JURY TRIAL. IN ANY ACTION, SUIT, OR PROCEEDING IN ANY JURISDICTION BROUGHT BY ANY PARTY AGAINST ANY OTHER PARTY, THE PARTIES
EACH KNOWINGLY AND INTENTIONALLY, TO THE GREATEST EXTENT PERMITTED BY APPLICABLE LAW, HEREBY ABSOLUTELY, UNCONDITIONALLY, IRREVOCABLY
AND EXPRESSLY WAIVES FOREVER TRIAL BY JURY.
