 For Executive Employee Agreements 
  
 Notwithstanding anything contained herein to the contrary, if (i) this option
is continued, assumed, converted or substituted for immediately following the Change in Control and (ii) within one year after a Change in Control the Optionee’s Business Relationship is terminated by the Company or its successor without Good
Cause or by the Optionee for Good Reason, all of the Option Shares shall be vested and this option may be exercised at any time within 12 months following such termination, but not later than the Final Exercise Date. Furthermore and notwithstanding
anything contained herein to the contrary, if this option is not continued, assumed, converted or substituted for immediately following the Change in Control, the Optionee shall receive a lump sum cash payment within 30 days after the Change in
Control in an amount equal to the result of multiplying the Option Shares which have not been exercised by the difference between (x) the Fair Market Value of one Share on the day immediately preceding the Change in Control and (y) the per share
exercise price of the option. This option shall be considered to be continued, assumed, converted or substituted for: 
  

	 	(A)	if there is no change in the number of outstanding Shares and the Change in Control does not result from the consummation of a merger, consolidation, statutory share exchange,
reorganization or similar form of corporate transaction, there are no changes to the terms and conditions of this option that materially and adversely affect this option, including the number of Option Shares and the exercise price of the option; or

  

	 	(B)	if there is a change in the number of outstanding Shares and/or the Change in Control does result from the consummation of a merger, consolidation, statutory share exchange,
reorganization or similar form of corporate transaction: (1) the Option Shares and the exercise price of the option are adjusted in a manner which is not materially less favorable than as provided under Section 424(a) of the Code and regulations
thereunder, (2) if applicable, the Option Shares are converted into the common stock of the Parent Corporation or, if there is no Parent Corporation, the Surviving Corporation (as such terms are defined below), and (3) there are no other changes to
the terms and conditions of this option that materially and adversely affect this option. 

  
 For purposes of this Agreement: 
  
 “Change in Control” means the occurrence of any one of the following events: 
  
 (i) individuals who, on the Grant Date, constitute the Board (the “Incumbent Directors”) cease for any reason to constitute at least a majority
of the Board, provided that any person becoming a director subsequent to the initial public offering whose election or nomination for election was approved by a vote of at least a majority of the Directors then on the Board (either 

  

 
by a specific vote or by approval of the proxy statement of the Company in which such person is named as a nominee for director, without written objection to
such nomination) shall be an Incumbent Director; provided, however, that no individual initially elected or nominated as a director of the Company as a result of an actual or threatened election contest with respect to directors or as
a result of any other actual or threatened solicitation of proxies by or on behalf of any person other than the Board shall be deemed to be an Incumbent Director; 
  
 (ii) any “person” (as such term is defined in the Exchange Act and as used in Sections 13(d)(3) and 14(d)(2) of
the Exchange Act) is or becomes a “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the Company representing 35% or more of the combined voting power of the Company’s then
outstanding securities eligible to vote for the election of the Board (the “Company Voting Securities”); provided, however, that the event described in this paragraph (ii) shall not be deemed to be a Change in Control by
virtue of any of the following acquisitions: (A) by the Company or any subsidiary, (B) by any employee benefit plan (or related trust) sponsored or maintained by the Company or any subsidiary, (C) by any underwriter temporarily holding securities
pursuant to an offering of such securities, (D) pursuant to a Non-Qualifying Transaction, as defined in paragraph (iii), or (E) by any person of Voting Securities from the Company, if a majority of the Incumbent Board approves in advance the
acquisition of beneficial ownership of 35% or more of Company Voting Securities by such person; 
  
 (iii) the consummation of a merger, consolidation, statutory share exchange, reorganization or similar form of corporate transaction involving the Company
or any of its subsidiaries that requires the approval of the Company’s stockholders, whether for such transaction or the issuance of securities in the transaction (a “Business Combination”), unless immediately following such Business
Combination: (A) more than 40% of the total voting power of (x) the corporation resulting from such Business Combination (the “Surviving Corporation”), or (y) if applicable, the ultimate parent corporation that directly or indirectly has
beneficial ownership of 100% of the voting securities eligible to elect directors of the Surviving Corporation (the “Parent Corporation”), is represented by Company Voting Securities that were outstanding immediately prior to such Business
Combination (or, if applicable, is represented by shares into which such Company Voting Securities were converted pursuant to such Business Combination), and such voting power among the holders thereof is in substantially the same proportion as the
voting power of such Company Voting Securities among the holders thereof immediately prior to the Business Combination, (B) no person (other than any employee benefit plan (or related trust) sponsored or maintained by the Surviving Corporation or
the Parent Corporation), is or becomes the beneficial owner, directly or indirectly, of 35% or more of the total voting power of the outstanding voting securities eligible to elect directors of the Parent Corporation (or, if there is no Parent
Corporation, the Surviving Corporation) and (C) at least half of the members of the board of directors of the Parent Corporation (or, if there is no Parent Corporation, the Surviving Corporation) following the consummation of the Business
Combination were Incumbent Directors at the time of the Board’s approval of the execution of the initial agreement providing for such Business Combination (any Business Combination which satisfies all of the criteria specified in (A), (B) and
(C) above shall be deemed to be a “Non-Qualifying Transaction”); 
  

 (iv) the stockholders of the Company approve a plan of complete liquidation or dissolution of the Company
or the consummation of a sale of all or substantially all of the Company’s assets; or 
  
 (v) the occurrence of any other event that the Board determines by a duly approved resolution constitutes a Change in Control. 
  

Notwithstanding the foregoing, a Change in Control shall not be deemed to occur solely because any person acquires beneficial ownership of more than 35% of the Company
Voting Securities as a result of the acquisition of Company Voting Securities by the Company which reduces the number of Company Voting Securities outstanding; provided, that if after such acquisition by the Company such person becomes
the beneficial owner of additional Company Voting Securities that increases the percentage of outstanding Company Voting Securities beneficially owned by such person, a Change in Control of the Company shall then occur. 
  
 “Good Cause” is as defined in Section 4(c). 
  
 “Good Reason” means: 
  
 (i) a reduction by the Company or its successor of more than 10% in
Optionee’s rate of annual base salary as in effect immediately prior to such Change in Control; 
  
 (ii) a reduction by the Company or its successor of more than 10% of the Optionee’s individual annual target or bonus opportunity, except under
circumstances where the Company or its successor implement changes to the bonus structure of similarly situated employees, including but not limited to changes to the bonus structure designed to integrate the Company’s personnel with other
personnel of the Surviving Corporation; 
  
 (iii) a significant
and substantial reduction by the Company or its successor of the Optionee’s responsibilities and authority, as compared with the Optionee’s responsibilities and authority in effect immediately preceding the Change in Control; or

  
 (iv) any requirement of the Company that Optionee be based
anywhere more than fifty (50) miles from Optionee’s primary office location at the time of the Change in Control.Securities Purchase Agreement, dated as of November 24, 2004

Subsidiaries is duly qualified to conduct business and is in good standing as a foreign corporation or other entity in each jurisdiction in which the nature of the business conducted or property owned by it makes such qualification necessary, except

material adverse effect on the results of operations, assets, business or financial condition of the Company and the Subsidiaries, taken as a whole, or (iii) a material adverse effect on the Company’s ability to perform in any material respect

 to which it is a party and the consummation by it of the transactions contemplated thereby have been duly
authorized by all necessary action on the part of the Company and no further action is required by the Company in connection therewith other than in connection with the Required Approvals. Each Transaction Document to which it is a party has been
(or upon delivery will have been) duly executed by the Company and, when delivered in accordance with the terms hereof, will constitute the valid and legally binding obligation of the Company enforceable against the Company in accordance with its
terms except (i) as limited by 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) as the rights to indemnification or contribution hereunder and thereunder may be limited by applicable law. 
  
 (d) No Conflicts. The execution, delivery and performance by the Company of the Transaction Documents
to which it is a party, the issuance and sale of the Shares and the consummation by the Company of the other transactions contemplated thereby do not and will not (i) conflict with or violate any provision of the Company’s or any
Subsidiary’s certificate or articles of incorporation, bylaws or other organizational or charter documents, or (ii) conflict with, or constitute a default (or an event that with notice or lapse of time or both would become a default) under,

Subsidiary is bound, or (iii) subject to the Required Approvals, conflict with or result in a violation of any law, rule, regulation, order, judgment, injunction, decree or other restriction of any court or governmental authority to which the
Company or a Subsidiary is subject (including federal and state securities laws and regulations), or by which any property or asset of the Company or a Subsidiary is bound, or (iv) violate the terms of any agreement by which the Company or any
Subsidiary is bound or to which any property or asset of the Company or any Subsidiary is bound; except in the case of each of clauses (ii), (iii) and (iv), such as would not have or reasonably be expected to result in a Material Adverse Effect.

  
 (e) Filings, Consents and Approvals.
The Company is not required to obtain any consent, waiver, authorization or order of, give any notice to, or make any filing or registration with, any court or other federal, state, local or other governmental authority or other Person in connection

Except as a result of the purchase and sale of the Securities, there are no outstanding options, warrants, script rights to subscribe to, calls or commitments of any character whatsoever relating to, or securities, rights or obligations convertible

additional shares of Common Stock, or securities or rights convertible or exchangeable into shares of Common Stock. The issue and sale of the Securities will not obligate the Company to issue shares of Common Stock or other securities to any Person
(other than the Purchasers) and will not result in a right of any holder of Company securities to adjust the exercise, conversion, exchange or reset price under such securities. All of the outstanding shares of capital stock of the Company are
validly issued, fully paid and nonassessable, have been issued in compliance with all federal and state securities laws, and none of such outstanding shares were issued in violation of any preemptive rights or similar rights to subscribe for or
purchase securities. No further approval or authorization of any shareholder, the Board of Directors of the Company or others is required for the issuance and sale of the Shares. Except as disclosed in the SEC Reports, there are no shareholders

There has not been, and to the knowledge of the Company, there is not pending, any investigation by the Commission involving the Company or any current or former director or officer of the Company. The Commission has not issued any stop order or
other order suspending the effectiveness of any registration statement filed by the Company or any Subsidiary under the Exchange Act or the Securities Act. 
  
 (k) Labor Relations. No material labor dispute exists or, to the knowledge of the Company, is imminent with respect to any of the
employees of the Company or any Subsidiary which would reasonably be expected to result in a Material Adverse Effect. 
  
 (l) Compliance. Neither the Company nor any Subsidiary (i) is in default under or in violation of (and no event has occurred that
has not been waived that, with notice or lapse of time or both, would result in a default by the Company or any Subsidiary under), nor has the Company or any Subsidiary received written notice of a claim that it is in default under, any indenture,
loan or credit agreement or any other agreement or instrument to which it is a party or by which it or any of its properties is bound (whether or not such default or violation has been waived), (ii) is in violation of any order of any court,
arbitrator or governmental body, or (iii) is in violation of any statute, rule or regulation of any governmental authority, including without limitation all foreign, federal, state and local laws applicable to its business, except in each case as
would not have a Material Adverse Effect. 
  
 (m)
Regulatory Permits. The Company and the Subsidiaries possess all certificates, authorizations and permits issued by the appropriate federal, state, local or foreign regulatory authorities necessary to conduct their respective businesses as
described in the SEC Reports, except where the failure to possess such permits would not have or reasonably be expected to result in a Material Adverse Effect (“Material Permits”), and neither the Company nor any Subsidiary has
received any written notice of proceedings relating to the revocation or modification of any Material Permit. 
  
 (n) Title to Assets. The Company and the Subsidiaries have good, marketable and fee simple title to all real property owned by them
that is material to the business of the Company and the Subsidiaries and valid title in all personal property owned by them that is material to the business of the Company and the 
  

 10 

 Subsidiaries, in each case free and clear of all Liens, except for Liens as do not materially affect the
value of such property and do not materially interfere with the use made and proposed to be made of such property by the Company and the Subsidiaries and Liens for the payment of federal, state or other taxes, the payment of which is neither
delinquent nor subject to penalties. Any real property and facilities held under lease by the Company and the Subsidiaries are held by them under valid, subsisting and enforceable leases and no landlord for any such real property or facility has
notified the Company or any such Subsidiary that any of them are in default under any such lease. 
  
 (o) Patents and Trademarks. The Company and the Subsidiaries have, or have rights to use, all patents, patent applications,
trademarks, trademark applications, service marks, trade names, copyrights, licenses and other similar rights necessary or material for use in connection with their respective businesses as described in the SEC Reports and which the failure to so
have would have a Material Adverse Effect (collectively, the “Intellectual Property Rights”). Neither the Company nor any Subsidiary has received a written notice that the Intellectual Property Rights used by the Company or any
Subsidiary violates or infringes upon the rights of any Person. To the knowledge of the Company, all such Intellectual Property Rights are enforceable and there is no known existing infringement by another Person of any of the Intellectual Property
Rights of others which would have a Material Adverse Effect. 
  
 (p) Insurance. The Company and the Subsidiaries are insured by insurers of recognized financial responsibility against such losses and risks and in such amounts as the Company believes are prudent and customary
in the businesses in which the Company and the Subsidiaries are engaged. Neither the Company nor any Subsidiary has any 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 without a significant increase in cost. 
  
 (q) Transactions With Affiliates and Employees. Except as set forth in the SEC Reports, none of the officers or directors of the
Company and, to the knowledge of the Company, none of the employees of the Company is presently a party to any transaction with the Company or any Subsidiary (other than for services as employees, officers and directors), including any contract,
agreement or other arrangement providing for the furnishing of services to or by, providing for rental of real or personal property to or from, or otherwise requiring payments to or from any officer, director or such employee or, to the knowledge of
the Company, any entity in which any officer, director, or any such employee has a substantial interest or is an officer, director, trustee or partner, in each case in excess of $60,000 other than (i) for payment of salary or consulting fees for
services rendered, (ii) reimbursement for expenses incurred on behalf of the Company and (iii) for other benefits under benefit or pension plans sponsored by the Company, including without limitation stock option agreements under any stock option
plan of the Company. 
  

 11 

 (r) Sarbanes-Oxley; Internal Accounting Controls. The Company is in material
compliance with all provisions of the Sarbanes-Oxley Act of 2002 which are applicable to it as of the Closing Date. The Company and the Subsidiaries maintain a system of internal accounting controls sufficient to provide reasonable assurance that
(i) transactions are executed in accordance with management’s general or specific authorizations, (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to maintain asset
accountability, (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 the existing assets at reasonable intervals and
appropriate action is taken with respect to any differences. The Company has established disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the Company and designed such disclosure controls and
procedures to ensure that material information relating to the Company, including its Subsidiaries, is made known to the certifying officers by others within those entities. The Company’s certifying officers have evaluated the effectiveness of
the Company’s controls and procedures as of the end of the period covered by its most recently filed periodic report under the Exchange Act (the date of such evaluation, the “Evaluation Date”). The Company presented in its most
recently filed periodic report under the Exchange Act the conclusions of the certifying officers about the effectiveness of the disclosure controls and procedures based on their evaluations as of the Evaluation Date. Since the Evaluation Date, there
have been no significant changes in the Company’s internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) or, to the best of the Company’s knowledge, in other factors that could significantly
affect the Company’s internal controls. 
  
 (s) Certain Fees. Except for amounts to be paid to The Shemano Group, no brokerage or finder’s fees or commissions are or will be payable by the Company or any Subsidiary to any broker, financial advisor or consultant, finder,
placement agent, investment banker, bank or other Person with respect to the transactions contemplated by this Agreement. To the knowledge of the Company, the Purchasers shall have no obligation with respect to any fees or with respect to any claims
made by or on behalf of other Persons for fees of a type contemplated in this Section that may be due in connection with the transactions contemplated by this Agreement. 
  
 (t) Private Placement. Assuming the accuracy of the Purchasers representations and warranties set
forth in Section 3.2, no registration under the Securities Act is required for the offer and sale of the Securities by the Company to the Purchasers as contemplated hereby. The issuance and sale of the Securities hereunder does not contravene
the rules and regulations of the Trading Market. 
  
 (u) Investment Company. The Company is not, and is not an Affiliate of, and immediately after receipt of payment for the Shares, will not be or be an Affiliate of, an “investment company” within the meaning of the
Investment Company Act of 1940, as amended. 
  

 12 

 (v) Registration Rights. No Person has any right to cause the Company to effect
the registration under the Securities Act of any securities of the Company. 
  
 (w) Listing and Maintenance Requirements. The Company’s Common Stock is registered pursuant to Section 12(g) of the Exchange Act, and the Company has taken no action designed to, or which to its knowledge
is likely to have the effect of, terminating the registration of the Common Stock under the Exchange Act nor has the Company received any written notification that the Commission is contemplating terminating such registration. The Company has not,
in the 12 months preceding the date hereof, received written notice from any Trading Market on which the Common Stock is or has been listed or quoted to the effect that the Company is not in compliance with the listing or maintenance requirements of
such Trading Market. The Company is currently in compliance with all such listing and maintenance requirements. 
  
 (x) Application of Takeover Protections. 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 Certificate of Incorporation (or similar
charter documents) or the laws of its state of incorporation that is or could become applicable to the Purchasers as a result of the Purchasers and the Company fulfilling their obligations or exercising their rights under the Transaction Documents,
including without limitation the Company’s issuance of the Securities and the Purchasers’ ownership of the Securities. 
  
 (y) Disclosure. Except as set forth in the Disclosure Schedule and except for terms of the Transaction Documents and the fact that
the Company is considering consummating the transactions contemplated therein, the Company confirms that, neither the Company 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 will rely on the foregoing representations and covenants in effecting transactions in securities of the
Company. All disclosure provided to the Purchasers regarding the Company, its business and the transactions contemplated hereby, including the Schedules to this Agreement, furnished by or on behalf of the Company with respect to the representations
and warranties made herein are true and correct with respect to such representations and warranties 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. The Company acknowledges and agrees that no Purchaser makes or has made any representations or warranties with respect to the transactions contemplated hereby other than those
specifically set forth in Section 3.2 hereof. 
  

 13 

 (z) No Integrated Offering. Assuming the accuracy of the Purchasers’
representations and warranties set forth in Section 3.2, 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 cause this offering of the Securities to be integrated with prior offerings by the Company for purposes of the Securities Act or any applicable shareholder approval provisions, including,
without limitation, under the rules and regulations of the Trading Market. 
  
 (aa) Solvency. Based on the 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 Securities hereunder, (i) the
Company’s fair saleable value of its 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) as they mature; (ii) the
Company’s assets do not constitute unreasonably small capital to carry on its business for the current fiscal year 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, 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 debt 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). 
  
 (bb) Form S-3 Eligibility. The Company is eligible to register the resale of its Common Stock by the Purchasers under Form S-3
promulgated under the Securities Act. 
  
 (cc)
Taxes. Except for matters that would not, individually or in the aggregate, have or reasonably be expected to result in a Material Adverse Effect, the Company and each Subsidiary has filed all necessary federal, state and foreign income and
franchise tax returns and has paid or accrued all taxes shown as due thereon, and the Company has no knowledge of a tax deficiency which has been asserted or threatened against the Company or any Subsidiary. 
  
 (dd) General Solicitation. Neither the Company nor
any person acting on behalf of the Company has offered or sold any of the Shares by any form of general solicitation or general advertising. The Company has offered the Shares for sale only to the Purchasers and certain other “accredited
investors” within the meaning of Rule 501 under the Securities Act. 
  

 14 

 (ee) Foreign Corrupt Practices. Neither the Company, nor to the knowledge of the
Company, any agent or other person acting on behalf of the Company, has (i) directly or indirectly, used any corrupt funds for unlawful contributions, gifts, entertainment or other unlawful expenses related to foreign or domestic political activity,
(ii) made any 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 made
by any person acting on its behalf of which the Company is aware) which is in violation of law, or (iv) violated in any material respect any provision of the Foreign Corrupt Practices Act of 1977, as amended. 
  
 (ff) Auditor. The Company’s auditors are set
forth on Schedule 3.1(ff) of the Disclosure Schedule. To the Company’s knowledge, such auditors are independent auditors as required by the Securities Act. 
  
 (gg) Acknowledgment Regarding Purchasers’ Purchase of Shares. The Company acknowledges and
agrees that each of the Purchasers is acting solely in the capacity of an arm’s length purchaser with respect to the Transaction Documents and the transactions contemplated hereby. The Company further acknowledges that no Purchaser is acting as
a financial advisor or fiduciary of the Company (or in any similar capacity) with respect to this Agreement and the transactions contemplated hereby. 
  
 3.2 Representations and Warranties of the Purchasers. Each Purchaser hereby, for itself and for no other Purchaser, represents and warrants as of
the date hereof and as of the Closing Date to the Company as follows: 
  
 (a) Organization; Authority. Such Purchaser is an entity duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization with full right, corporate or partnership
power and authority to enter into and to consummate the transactions contemplated by the Transaction Documents and otherwise to carry out its obligations thereunder. The execution, delivery and performance by such Purchaser of the transactions
contemplated by this Agreement have been duly authorized by all necessary corporate or similar action on the part of such Purchaser. Each Transaction Document to which it is 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. 
  
 (b) Investment Intent. Such Purchaser understands that the Securities are “restricted securities” and have not been
registered under the Securities Act or any 
  

 15 

 applicable state securities law and is acquiring the Securities as principal for its own account for
investment purposes only and not with a view to or for distributing or reselling such Securities or any part thereof, has no present intention of distributing any of such Securities and has no arrangement or understanding with any other persons
regarding the distribution of such Securities (this representation and warranty not limiting such Purchaser’s right to sell the Securities pursuant to the Registration Statement or otherwise in compliance with applicable federal and state
securities laws). Such Purchaser is acquiring the Securities hereunder in the ordinary course of its business. Such Purchaser does not have any agreement or understanding, directly or indirectly, with any Person to distribute any of the Securities.

  
 (c) Purchaser Status. At the time such
Purchaser was offered the Securities, it was, and at the date hereof it is, and on each date on which it exercises any Warrants, it will be either: (i) an “accredited investor” as defined in Rule 501(a)(1), (a)(2), (a)(3), (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 Securities, 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 Securities and, at the present time, is able to afford a complete loss of such investment. 
  
 (e) General Solicitation. Such Purchaser is not
purchasing the Securities as a result of any advertisement, article, notice or other communication regarding the Securities 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. 
  
 The
Company acknowledges and agrees that each Purchaser does not make or has not made any representations or warranties with respect to the transactions contemplated hereby other than those specifically set forth in this Section 3.2. 

 
 ARTICLE IV. 
 OTHER AGREEMENTS OF THE PARTIES 
  
 4.1 Transfer Restrictions. 
  
 (a) Each of the Purchasers hereby acknowledges that the Securities may only be disposed of in compliance with state and federal securities laws. In connection with any transfer of Securities other than pursuant to an
effective registration statement or Rule 144, to the Company or to an Affiliate of a 
  

 16 

 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 form and substance of such opinion shall be reasonably satisfactory to the Company, to the effect
that such transfer does not require registration of such transferred Securities under the Securities Act. As a condition of any such transfer, any such transferee shall agree in writing to be bound by the terms of this Agreement and shall have the
rights of a Purchaser under this Agreement and the Registration Rights Agreement and/or a Holder (as defined in the Warrants) under the Warrants, as applicable. 
  
 (b) The Purchasers agree to the imprinting, so long as is required by this Section 4.1(b), of a
legend on any of the Securities in the following form: 
  
 THESE
SECURITIES HAVE 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. THESE SECURITIES 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. 
  
 (c) 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 Securities 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 Securities 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 
  

 17 

 documentation as a pledgee or secured party of Securities may reasonably request in connection with a
pledge or transfer of the Securities, including, if the Securities 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 thereunder. 
  
 (d) Certificates evidencing the Shares and Warrant Shares shall not contain any legend (including the legend set forth in Section
4.1(b)), (i) while a registration statement (including the Registration Statement) covering the resale of such security is effective under the Securities Act, or (ii) following any sale of such Shares or Warrant Shares pursuant to Rule 144, or
(iii) if such Shares or Warrant Shares are eligible for sale under Rule 144(k), 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 Company’s transfer agent promptly after the Effective Date if required by the Company’s transfer agent to effect the removal of the legend hereunder. If
all or any portion of a Warrant is exercised at a time when there is an effective registration statement to cover the resale of the Warrant Shares, such Warrant Shares shall be issued free of all legends. The Company agrees that following the
Effective Date or at such time as such legend is no longer required under this Section 4.1(d), it will, no later than seven (7) Trading Days following the delivery by a Purchaser to the Company or the Company’s transfer agent of a
certificate representing Shares or Warrant Shares, as the case may be, issued with a restrictive legend (such date, the “Legend Removal Date”), 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 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.

  
 (e) 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 $1,000 of Shares or Warrant Shares (based on the Closing Price of the Common Stock on the date certificate(s)
representing such Securities are submitted to the Company’s transfer agent) subject to Section 4.1(d), $5 per Trading Day (increasing to $10 per Trading Day ten (10) Trading Days after such damages have begun to accrue) for each Trading
Day after the Legend Removal Date until such certificate is delivered to such Purchaser. Nothing herein shall limit such Purchaser’s right to pursue actual damages for the Company’s failure to deliver certificates representing any
Securities 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.

  
 (f) Each Purchaser, severally and not jointly
with the other Purchasers, agrees that the removal of the restrictive legend from certificates representing 
  

 18 

 Securities as set forth in this Section 4.1 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. 
  
 (g) Until 30 days after the Effective Date, the Company
shall not undertake a reverse or forward stock split or reclassification of the Common Stock without the prior written consent of the Purchasers holding a majority in interest of the Shares. 
  
 4.2 Furnishing of Information. As long as any Purchaser owns
Securities, the Company covenants 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. As long as any
Purchaser owns Securities, if the Company is no longer required to file reports pursuant to the Exchange Act (or if such filings are not otherwise generally available on the Internet free of charge), it will prepare and furnish to the Purchasers
(upon receipt of a written request) and make publicly available in accordance with Rule 144(c) such information as is required for the Purchasers to sell the Securities under Rule 144. The Company further covenants that it will take such further
action as any holder of Securities may reasonably request, all to the extent required from time to time to enable such Person to sell such Securities without registration under the Securities Act within the limitation of the exemptions provided by
Rule 144. 
  
 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 Securities in a manner that would require the
registration under the Securities Act of the sale of the Securities to the Purchasers or that would be integrated with the offer or sale of the Securities 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. Provided that the Company has received each item required to be delivered by each Purchaser pursuant
to Section 2.2(c), the Company shall, by 9:00 a.m. Eastern time on the Trading Day following the Closing Date, issue a press release or file a Current Report on Form 8-K in each case reasonably acceptable to Weiss, Peck & Greer
Investments, a division of Robeco USA, LLC (“WPG”), disclosing the material terms of the transactions contemplated hereby. Neither the Company nor any Purchaser shall issue any press release with respect to the transaction contemplated
hereby or otherwise make any such public statement without the prior consent of the Company, with respect to any press release of any Purchaser, or without the prior consent of WPG, with respect to any press release of the Company, which consent
shall not unreasonably be withheld, except if such disclosure is required by law, in which case the disclosing party shall promptly provide the other party with prior notice of such public statement or communication; provided, however,
that only such portions of any press release to be issued by the Company that specifically reference 
  

 19 

 the transactions contemplated by the Transaction Documents shall be provided to WPG and be subject to their prior
consultation and approval. 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 (i) as required by federal securities law in connection with the registration statement contemplated by the Registration Rights Agreement and (ii) 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 subclause (i) or (ii). 
  
 4.5 Shareholders Rights Plan. No claim will be made or enforced by the Company or, to the knowledge of the Company,
any other Person that any Purchaser is an “Acquiring Person” under any shareholders rights plan or similar 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 Securities under the Transaction Documents. 
  
 4.6 Non-Public Information. Except as may be required to comply with the terms and conditions of this Agreement, 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. 
  
 4.7 Use of Proceeds. Except as set forth on
Schedule 4.7 attached hereto, the Company shall use the net proceeds from the sale of the Securities hereunder for general corporate and strategic purposes, including, but not limited to, in connection with acquisitions, joint ventures and
other similar transactions, and not 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), to redeem any Company equity or
equity-equivalent securities or to settle any outstanding litigation. 
  
 4.8 Intentionally Omitted. 
  
 4.9 Indemnification of
Purchasers. Subject to the provisions of this Section 4.9, the Company will indemnify and hold the Purchasers and their directors, officers, shareholders, partners, employees and agents (each, a “Purchaser Party”)
harmless from any and all losses, liabilities, obligations, claims, contingencies, damages, costs and expenses, including without limitation 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 (i) a Purchaser, or any of them or their respective Affiliates or (ii) a Purchaser Party, by any shareholder of the Company who is not an Affiliate of such Purchaser or Purchaser Party, 
  

 20 

 with respect to any of the transactions contemplated by the Transaction Documents (unless such action is based upon a
breach of such Purchaser’s representation, warranties, covenants or agreements under the Transaction Documents or any agreements or understandings such Purchaser or a Purchaser Party may have with any such shareholder or any violations by the
Purchaser or a Purchaser Party of state or federal securities laws or any conduct by such Purchaser or a 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. 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 such separate counsel, a material conflict on any material issue between the position of the Company and the position of such Purchaser Party. The Company will not be liable to any Purchaser Party under this Agreement (i) for
any settlement by an Purchaser Party effected without the Company’s prior written consent, which shall not be unreasonably withheld or delayed; or (ii) 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 the Purchasers in this Agreement or in the other Transaction Documents. 
  
 4.10 Reservation of Common Stock. As of the date hereof, the Company
has reserved and the Company shall continue to reserve and keep available at all times, free of preemptive rights, a sufficient number of shares of Common Stock for the purpose of enabling the Company to issue Shares pursuant to this Agreement and
Warrant Shares pursuant to any exercise of the Warrants. 
  
 4.11
Listing of Common Stock. The Company hereby agrees to use commercially reasonable efforts to maintain the listing of the Common Stock on a Trading Market, and as soon as reasonably practicable following the Closing (but not later than the
earlier of the Effective Date and the first anniversary of the Closing Date) to list all of the Shares and Warrant Shares on such Trading Market. The Company further agrees, if the Company applies to have the Common Stock traded on any other Trading
Market, it will include in such application all of the Shares and Warrant Shares, and will take such other action as is necessary to cause all of the Shares and Warrant Shares to be listed on such other Trading Market as promptly as possible. The
Company will take all action commercially reasonable and necessary to (a) continue the listing and trading of its Common Stock on a Trading Market and (b) comply in all respects with the Company’s reporting, filing and other obligations under
the bylaws or rules of such Trading Market. 
  
 4.12 Equal
Treatment of Purchasers. No consideration shall be offered or paid to any Person to amend or consent to a waiver or modification of any provision of any of the Transaction Documents unless the same consideration is also offered to all of the

 parties to the Transaction Documents. 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 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 or otherwise. 
  
 4.13
Participation in Future Financing. From the date hereof until the earlier of the six month anniversary after the Effective Date or the date the first Subsequent Financing (as defined below) closes, if the Company desires to effect an offering
of its Common Stock or Common Stock Equivalents for an aggregate offering price of at least $6,071,988 (a “Subsequent Financing”), each Purchaser shall have the right to participate in such Subsequent Financing in its proportionate
amount of $6,071,988 of the Subsequent Financing based on such Purchaser’s proportionate amount of the Common Stock issued to all Purchasers at the Closing. At least four (4) Trading Days prior to the closing of the Subsequent Financing, the
Company shall deliver to each Purchaser a written notice of its intention to effect a Subsequent Financing (such notice, a “Subsequent Financing Notice”). The Subsequent Financing Notice shall describe in reasonable detail the
proposed terms of such Subsequent Financing, the amount of proceeds intended to be raised thereunder, the Person with whom such Subsequent Financing is proposed to be effected, and attached to which shall be a term sheet or similar document relating
thereto. If by 6:30 p.m. (New York City time) on the fourth Trading Day after the Purchasers have received the Subsequent Financing Notice (i) a Purchaser has notified the Company that it (or its affiliated designee) does not elect to participate in
the Subsequent Financing, or (ii) a Purchaser has notified the Company that its (or its affiliated designee’s) willingness to participate in the Subsequent Financing is less than the total amount of the Subsequent Financing, then the Company
may effect such Subsequent Financing or the remaining portion of such Subsequent Financing, as applicable, on the terms and to the Persons set forth in the Subsequent Financing Notice. If the Company receives no notice from a Purchaser as of such
fourth Trading Day after the Purchasers have received the Subsequent Financing Notice, such Purchaser shall be deemed to have notified the Company that it does not elect to participate. The Company must provide each Purchaser with a second
Subsequent Financing Notice, and each Purchaser will again have the right of participation set forth above in this Section 4.13, if the Subsequent Financing subject to the initial Subsequent Financing Notice is not consummated for any reason
on the terms set forth in such Subsequent Financing Notice within 60 days after the date of the initial Subsequent Financing Notice. Notwithstanding the foregoing, this Section 4.13 shall not apply to (a) shares of Common Stock or options to
consultants, employees, officers or directors of the Company pursuant to any stock or option plan duly adopted by the Company or to the issuance of Common Stock upon exercise of such options, (b) any equity securities issued pursuant to any
equipment leasing arrangement or debt financing from a bank or similar financial institution whose primary business is lending money and not investing in securities, (c) any equity securities issued in connection with strategic transactions
involving the Company and other entities, the primary purpose of which is not to raise capital, including (A) joint ventures, manufacturing, marketing or distribution arrangements or (B) technology transfer or development arrangements (provided that
the primary purpose of such transaction is not the raising of capital), (d) any securities issued for consideration other 
  

 22 

 than cash pursuant to a merger, consolidation, acquisition or similar business combination, (e) any securities issued in
connection with the settlement of pending or threatened litigation or similar proceeding, (f) shares of Common Stock issued in conjunction with any stock split, stock dividend or recapitalization of the Company, (g) any securities issuable upon the
exercise or conversion of, or pursuant to the anti-dilution provisions contained within, any agreement, option, restricted stock awards, preferred stock, promissory note, convertible promissory note or warrants outstanding on the date hereof (but
not to the extent amended hereafter), (h) any shares of Common Stock issuable under the Transaction Documents (including those issued pursuant to the anti-dilution provisions contained therein), and (i) shares of Common Stock issued to vendors in
exchange for services rendered to the Company. 
  
 4.14
Delivery of Securities After Closing. The Company shall deliver, or cause to be delivered, the respective Shares and Warrants purchased by each Purchaser to such Purchaser within three (3) Trading Days of the Closing Date. 
  
 ARTICLE V. 
 MISCELLANEOUS 
  
 5.1 Fees and Expenses. Each party shall pay the fees and expenses of its advisers, counsel, accountants and other experts, if any, and all other expenses incurred by such party incident to the negotiation, preparation, execution,
delivery and performance of this Agreement, except that the Company shall pay up to an aggregate of $10,000 for the fees and expenses of TRP incurred in connection with the transactions contemplated hereby. The Company shall pay all stamp and other
taxes and duties levied in connection with the sale of the Securities. 
  
 5.2 Entire Agreement. The Transaction Documents, together with the exhibits and schedules thereto, contain the entire understanding of the parties with respect to the subject matter hereof and supersede all prior agreements and
understandings, oral or written, with respect to such matters, which the parties acknowledge have been merged into such documents, exhibits and schedules. 
  
 5.3 Notices. Any and all notices or other communications or deliveries required or permitted to be provided hereunder shall be in writing and shall
be deemed given and effective on the earliest of (a) the date of transmission, if such notice or communication is delivered via facsimile with confirmation of receipt at the facsimile number set forth on the signature pages attached hereto prior to
6:30 p.m. (New York City time) on a Trading Day, (b) the next Trading Day after the date of transmission, if such notice or communication is delivered via facsimile with confirmation of receipt at the facsimile number set forth on the signature
pages attached hereto on a day that is not a Trading Day or later than 6:30 p.m. (New York City time) on any Trading Day, (c) the second Trading Day following the date of mailing, if sent by a nationally recognized overnight courier service in the
United States, or (d) upon actual receipt by the party to whom such notice is required to be given. The address for such notices and communications shall be as set forth on the signature pages attached hereto. 
  

 23 

 5.4 Amendments; Waivers. No provision of this Agreement may be waived or amended except in a
written instrument signed, in the case of an amendment, by the Company and each Purchaser or, in the case of a waiver, by the party against whom enforcement of any such waiver 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 either
party to exercise any right hereunder in any manner impair the exercise of any such right. 
  
 5.5 Construction. 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. The language used in this
Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rules of strict construction will be applied against any party. 
  
 5.6 Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties hereto 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. Any Purchaser may assign any or all of its rights under this Agreement to
any Person to whom such Purchaser assigns or transfers any Securities, provided such transferee agrees in writing to be bound, with respect to the transferred Securities, by the provisions hereof that apply to the “Purchasers.” 

 
 5.7 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 4.9. 
  
 5.8 Governing Law. All questions concerning the construction,
validity, enforcement and interpretation of this Agreement 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 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 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 manner permitted by law. The parties hereby waive all rights to a trial by jury. If
either party shall commence an action or proceeding to enforce any provisions of this Agreement, then the prevailing 
  

 24 

 party in such action or proceeding shall be reimbursed by the other party for its reasonable attorneys fees and expenses
and other costs and expenses incurred with the investigation, preparation and prosecution of such action or proceeding. 
  
 5.9 Survival. The representations and warranties herein shall survive the Closing and delivery of the Shares and Warrant Shares until the third
anniversary hereof. 
  
 5.10 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 the other party, it being
understood that both parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission, 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 signature page were an original thereof. 
  
 5.11 Severability. If any provision of this Agreement is held to be invalid or unenforceable in any respect, the validity and enforceability of the
remaining terms and provisions of this Agreement shall not in any way be affected or impaired thereby and the parties will attempt to agree upon a valid and enforceable provision that is a reasonable substitute therefor, and upon so agreeing, shall
incorporate such substitute provision in this Agreement. 
  
 5.12
Rescission and Withdrawal Right. Notwithstanding anything to the contrary contained in (and without limiting any similar provisions of) the 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. 
  
 5.13 Replacement of Securities. If any certificate or instrument evidencing any Securities is mutilated, lost, stolen or destroyed, the Company
shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof, 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 and customary and reasonable indemnity, if requested. The applicants for a new certificate or instrument under such circumstances shall also pay any reasonable third-party costs associated with the issuance of such
replacement Securities. 
  
 5.14 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 described in the foregoing sentence and hereby agrees to waive in any action for specific performance of any such obligation the defense that a
remedy at law would be adequate. 
  

 25 

 5.15 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. 
  
 5.16 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 of the obligations of any other Purchaser under any Transaction Document. Nothing contained herein or in any Transaction Document, and no action taken by any Purchaser pursuant 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 Document. 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. 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 the Purchasers. 
  
 5.17 Liquidated Damages. The Company’s obligations to pay any partial liquidated damages or other amounts owing under the Transaction
Documents is a continuing obligation of the Company and shall not terminate until all unpaid partial liquidated damages and other amounts have been paid notwithstanding the fact that the instrument or security pursuant to which such partial
liquidated damages or other amounts are due and payable shall have been canceled.
