 - 2 - 








 
that by making the representations herein, such Buyer does not agree to hold any of the Securities for any minimum or other specific term and reserves the

 (d) Reliance on Exemptions. Such Buyer
understands that the Securities are being offered and sold to it in reliance on specific exemptions from the registration requirements of United States federal and state securities laws and that the Company is relying in part upon the truth and

obligation to register the Securities under the 1933 Act or any state securities laws or to comply with the terms and conditions of any exemption thereunder. The Securities may be pledged pursuant to an available exemption from registration under
the 1933 Act in connection with a bona fide margin account or other loan or financing arrangement secured by the Securities and such pledge of Securities shall not be deemed to be a transfer, sale or assignment of the Securities hereunder, and no
Buyer effecting a pledge of Securities shall be required to provide the Company with any notice thereof or otherwise make any delivery to the Company pursuant to this Agreement or any other Transaction Document (as defined in Section 3(b)),
including, without limitation, this Section 2(f).

legend as required by the “blue sky” laws of any state and a restrictive legend in substantially the following form (and a stop-transfer order may be placed against transfer of such stock certificates): 
  
 NEITHER THE ISSUANCE AND SALE OF THE SECURITIES REPRESENTED BY THIS
CERTIFICATE NOR THE SECURITIES INTO WHICH THESE SECURITIES ARE [CONVERTIBLE] [EXERCISABLE] HAVE BEEN] [THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN] REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE
SECURITIES LAWS. THE SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED (I) IN THE ABSENCE OF (A) AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND APPLICABLE STATE
SECURITIES LAWS, OR (B) AN OPINION OF COUNSEL, IN A GENERALLY ACCEPTABLE FORM, THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT AND APPLICABLE STATE SECURITIES LAWS OR (II) UNLESS SOLD PURSUANT TO RULE 144(K) UNDER SAID ACT.

certificate without such legend to the holder of the Securities upon which it is stamped, if, unless otherwise required by state securities laws, (i) such Securities are registered for resale under the 1933 Act, (ii) in connection with a
sale, assignment or other transfer, such holder provides the Company with an

transferred pursuant to Rule 144(k). 
  
 (i)
Validity; Enforcement. This Agreement and the Registration Rights Agreement to which such Buyer is a party have been duly and validly authorized, executed and delivered on behalf of such Buyer and shall constitute the legal, valid and binding
obligations of such Buyer enforceable against such Buyer in accordance with their respective terms, except as such enforceability may be limited by general principles of equity or to applicable bankruptcy, insolvency, reorganization, moratorium,
liquidation and other similar laws relating to, or affecting generally, the enforcement of applicable creditors’ rights and remedies. 
  
 (j) No Conflicts. The execution, delivery and performance by such Buyer of this Agreement and the Registration Rights Agreement to
which such Buyer is a party and the consummation by such Buyer of the transactions contemplated hereby and thereby will not (i) result in a violation of the organizational documents of such Buyer or (ii) conflict with, or constitute a
default (or an event which with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, any agreement, indenture or instrument to which such Buyer is a
party, or (iii) result in a violation of any law, rule, regulation, order, judgment or decree (including federal and state securities laws) applicable to such Buyer, except in the case of clauses (ii) and (iii) above, for such
conflicts, defaults, rights or violations which would not, individually or in the aggregate, reasonably be expected to have a material adverse effect on the ability of such Buyer to perform its obligations hereunder.

making investment decisions for such Buyer, is a resident of that jurisdiction specified below its address on the Schedule of Buyers. 
  
 3. REPRESENTATIONS AND WARRANTIES OF THE COMPANY. 
  
 Except as set forth on the Schedule of Exceptions attached hereto as Exhibit H (the “Schedule of Exceptions”) delivered to the
Buyers in connection with this Agreement, the Company represents and warrants to each of the Buyers that: 
  
 (a) Organization and Qualification. The Company and its “Subsidiaries” (which for purposes of this Agreement means
any entity in which the Company, directly or indirectly, owns 50% or more of the capital stock or similar interest) are entities duly organized and validly existing in good standing under the laws of the jurisdiction in which they are formed, and
have the requisite power and authorization to own their properties and to carry on their business as now being conducted. Each of the Company and its Subsidiaries is duly qualified as a foreign entity to do business and is in good standing in every
jurisdiction in which its ownership of property or the nature of the business conducted by it makes such qualification necessary, except to the extent that the failure to be so qualified or be in good standing would not have a Material Adverse
Effect. As used in this Agreement, “Material Adverse Effect” means 

  

 - 5 - 








 
any material adverse effect on the business, properties, assets, operations, results of operations, or condition (financial or otherwise) of the Company and
its Subsidiaries, taken as a whole, or on the transactions contemplated hereby and by the other Transaction Documents or by the agreements and instruments to be entered into in connection herewith or therewith, or on the authority or ability of the
Company to perform its obligations under the Transaction Documents (as defined below). The Company has no Subsidiaries. 
  
 (b) Authorization; Enforcement; Validity. The Company has the requisite corporate power and authority to enter into and perform its
obligations under this Agreement, the Notes, the Warrants, the Registration Rights Agreement, the Irrevocable Transfer Agent Instructions (as defined in Section 5(b)), and each of the other agreements entered into by the parties hereto in
connection with the transactions contemplated by this Agreement (collectively, the “Transaction Documents”) and to issue the Securities in accordance with the terms hereof and thereof. The execution and delivery of the Transaction
Documents by the Company and the consummation by the Company of the transactions contemplated hereby and thereby, including, without limitation, the issuance of the Notes, the reservation for issuance and the issuance of the Conversion Shares
issuable upon conversion of the Notes, the issuance of the Warrants and the reservation for issuance and issuance of the Warrant Shares issuable upon exercise of the Warrants, have been duly authorized by the Company’s Board of Directors and
(other than the filing with the SEC of one or more Registration Statements in accordance with the requirements of the Registration Rights Agreement and any other filings as may be required by any state securities agencies) no further filing,
consent, or authorization is required by the Company, its Board of Directors or its stockholders. This Agreement and the other Transaction Documents of even date herewith have been duly executed and delivered by the Company, and constitute the
legal, valid and binding obligations of the Company, enforceable against the Company in accordance with their respective terms, except as such enforceability may be limited by general principles of equity or applicable bankruptcy, insolvency,
reorganization, moratorium, liquidation or similar laws relating to, or affecting generally, the enforcement of applicable creditors’ rights and remedies. 
  

(c) Issuance of Securities. The issuance of the Notes and the Warrants are duly authorized and upon issuance in accordance with
the terms of the Transaction Documents shall be free from all taxes, liens and charges with respect to the issue thereof. As of the Closing, the Company shall have reserved from its duly authorized capital stock not less than the sum of
(i) 120% of the maximum number of shares of Common Stock issuable upon conversion of the Notes (assuming for purposes hereof, that the Notes are convertible at the Conversion Price and without taking into account any limitations on the
conversion of the Notes set forth in the Notes) and (ii) 120% of the maximum number of shares of Common Stock issuable upon exercise of the Warrants (without taking into account any limitations on the exercise of the Warrants set forth in the
Warrants). Upon issuance or conversion in accordance with the Notes or exercise in accordance with the Warrants, as the case may be, the Interest Shares, the Conversion Shares and the Warrant Shares, respectively, will be validly issued, fully paid
and nonassessable and free from all preemptive or similar rights, taxes, liens and charges with respect to the issue thereof, with the holders being entitled to all rights accorded to a holder of Common Stock. The offer and issuance by the Company
of the Securities is exempt from registration under the 1933 Act.

 (d) No Conflicts. The execution, delivery and performance of the Transaction
Documents by the Company and the consummation by the Company of the transactions contemplated hereby and thereby (including, without limitation, the issuance of the Notes, the Warrants, and reservation for issuance of the Conversion Shares and the
Warrant Shares and Interest Shares, if any) will not (i) result in a violation of the Certificate of Incorporation (as defined in Section 3(r)) of the Company or any of its Subsidiaries, any capital stock of the Company or Bylaws (as
defined in Section 3(r)) of the Company or any of its Subsidiaries or (ii) conflict with, or constitute a default (or an event which with notice or lapse of time or both would become a default) under, or give to others any rights of
termination, amendment, acceleration or cancellation of, any agreement, indenture or instrument to which the Company or any of its Subsidiaries is a party, except to the extent such conflict, default or termination right would not reasonably be
expected to have a Material Adverse Effect, or (iii) result in a violation of any law, rule, regulation, order, judgment or decree (including federal and state securities laws and regulations and the rules and regulations of the Nasdaq National
Market (the “Principal Market”)) applicable to the Company or any of its Subsidiaries or by which any property or asset of the Company or any of its Subsidiaries is bound or affected except to the extent such violation would not
reasonably be expected to have a Material Adverse Effect. 
  
 (e) Consents. The Company is not required to obtain any consent, authorization or order of, or make any filing or registration with, any court, governmental agency or any regulatory or self-regulatory agency or
any other Person in order for it to execute, deliver or perform any of its obligations under or contemplated by the Transaction Documents, in each case in accordance with the terms hereof or thereof. All consents, authorizations, orders, filings and
registrations which the Company is required to obtain pursuant to the preceding sentence have been obtained or effected on or prior to the Closing Date, and the Company and its Subsidiaries are unaware of any facts or circumstances which might
prevent the Company from obtaining or effecting any of the registration, application or filings pursuant to the preceding sentence. The Company is not in violation of the listing requirements of the Principal Market and has no knowledge of any facts
which would reasonably lead to delisting or suspension of the Common Stock in the foreseeable future. 
  
 (f) Acknowledgment Regarding Buyer’s Purchase of Securities. The Company acknowledges and agrees that each Buyer is acting
solely in the capacity of arm’s length purchaser with respect to the Transaction Documents and the transactions contemplated hereby and thereby and that no Buyer is (i) an officer or director of the Company, (ii) an
“affiliate” of the Company (as defined in Rule 144) or (iii) to the knowledge of the Company, a “beneficial owner” of more than 10% of the shares of Common Stock (as defined for purposes of Rule 13d-3 of the Securities
Exchange Act of 1934, as amended (the “1934 Act”)). The Company further acknowledges that no Buyer is acting as a financial advisor or fiduciary of the Company (or in any similar capacity) with respect to the Transaction Documents
and the transactions contemplated hereby and thereby, and any advice given by a Buyer or any of its representatives or agents in connection with the Transaction Documents and the transactions contemplated hereby and thereby is merely incidental to
such Buyer’s purchase of the Securities. The Company further represents to each Buyer that the Company’s decision to enter into the Transaction Documents has been based solely on the independent evaluation by the Company and its
representatives. 
  

 - 7 - 








 (g) No General Solicitation; Placement Agent’s Fees. Neither the Company, nor
any of its affiliates, nor any Person acting on its or their behalf, has engaged in any form of general solicitation or general advertising (within the meaning of Regulation D) in connection with the offer or sale of the Securities. The Company
shall be responsible for the payment of any placement agent’s fees, financial advisory fees, or brokers’ commissions (other than for persons engaged by any Buyer or its investment advisor) relating to or arising out of the transactions
contemplated hereby. The Company shall pay, and hold each Buyer harmless against, any liability, loss or expense (including, without limitation, attorney’s fees and out-of-pocket expenses) arising in connection with any such claim. The Company
acknowledges that it has engaged Rothschild Inc. as placement agent (the “Agent”) in connection with the sale of the Securities. Other than the Agent, the Company has not engaged any placement agent or other agent in connection with
the sale of the Securities. 
  
 (h) No
Integrated Offering. None of the Company, its Subsidiaries, any of their affiliates, and any Person acting on their behalf has, directly or indirectly, made any offers or sales of any security or solicited any offers to buy any security, under
circumstances that would require registration of any of the Securities under the 1933 Act or cause this offering of the Securities to be integrated with prior offerings by the Company for purposes of the 1933 Act or any applicable stockholder
approval provisions, including, without limitation, under the rules and regulations of any exchange or automated quotation system on which any of the securities of the Company are listed or designated. None of the Company, its Subsidiaries, their
affiliates and any Person acting on their behalf will take any action or steps referred to in the preceding sentence that would require registration of any of the Securities under the 1933 Act or cause the offering of the Securities to be integrated
with other offerings. 
  
 (i) Dilutive
Effect. The Company understands and acknowledges that the number of Conversion Shares issuable upon conversion of the Notes, and, the Warrant Shares issuable upon exercise of the Warrants, will increase in certain circumstances. The Company
further acknowledges that its obligation to issue Conversion Shares upon conversion of the Notes in accordance with this Agreement and the Notes and its obligation to issue the Warrant Shares upon exercise of the Warrants in accordance with this
Agreement and the Warrants is, in each case, absolute and unconditional regardless of the dilutive effect that such issuance may have on the ownership interests of other stockholders of the Company. 
  
 (j) Application of Takeover Protections; Rights
Agreement. The Company and its Board of Directors have taken all necessary action, if any, in order to render inapplicable any control share acquisition, business combination, poison pill (including any distribution under a rights agreement) or
other similar anti-takeover provision under the Certificate of Incorporation or the laws of the jurisdiction of its formation which is or could become applicable to any Buyer as a result of the transactions contemplated by this Agreement, including,
without limitation, the Company’s issuance of the Securities and any Buyer’s ownership of the Securities. 
  
 (k) SEC Documents; Financial Statements. During the two (2) years prior to the date hereof, the Company has filed all reports,
schedules, forms, statements and other documents required to be filed by it with the SEC pursuant to the reporting requirements of the 1934 Act (all of the foregoing filed prior to the date hereof and all exhibits included therein and financial
statements, notes and schedules thereto and documents incorporated by reference therein being hereinafter referred to as the “SEC Documents”). The Company has delivered to 

  

 - 8 - 








 
the Buyers or their respective representatives true, correct and complete copies of each of the SEC Documents not available on the EDGAR system that have
been requested by each Buyer. As of their respective dates, the SEC Documents complied in all material respects with the requirements of the 1934 Act and the rules and regulations of the SEC promulgated thereunder applicable to the SEC Documents,
and none of the SEC Documents, at the time they were filed with the SEC, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in the
light of the circumstances under which they were made, not misleading. As of their respective dates, the financial statements of the Company included in the SEC Documents complied as to form in all material respects with applicable accounting
requirements and the published rules and regulations of the SEC with respect thereto as in effect as of the time of filing. Such financial statements have been prepared in accordance with generally accepted accounting principles, consistently
applied, during the periods involved (except (i) as may be otherwise indicated in such financial statements or the notes thereto, or (ii) in the case of unaudited interim statements, to the extent they may exclude footnotes or may be
condensed or summary statements) and fairly present in all material respects the financial position of the Company as of the dates thereof and the results of its operations and cash flows for the periods then ended (subject, in the case of unaudited
statements, to normal year-end audit adjustments). 
  
 (l) Absence of Certain Changes. Except as disclosed in Section 3(l) of the Schedule of Exceptions, since September 30, 2005, there has been no material adverse change and no material adverse development in the business,
assets, properties, operations, condition (financial or otherwise) or results of operations of the Company. Since September 30, 2005, and except as otherwise disclosed in the SEC Documents, the Company has not (i) declared or paid any
dividends, (ii) sold any assets, individually or in the aggregate, in excess of $100,000 outside of the ordinary course of business or (iii) had capital expenditures, individually or in the aggregate, in excess of $100,000. The Company has

would reasonably lead a creditor to do so. The Company is not as of the date hereof, and after giving effect to the transactions contemplated hereby to occur at the Closing, will not be Insolvent (as defined below). For purposes of this
Section 3(l), “Insolvent” means (i) the present fair saleable value of the Company’s assets is less than the amount required to pay the Company’s total Indebtedness (as defined in Section 3(s)),
(ii) the Company is unable to pay its debts and liabilities, subordinated, contingent or otherwise, as such debts and liabilities become absolute and matured, (iii) the Company intends to incur or believes that it will incur debts that
would be beyond its ability to pay as such debts mature or (iv) the Company has unreasonably small capital with which to conduct the business in which it is engaged as such business is now conducted and is proposed to be conducted. 

 
 (m) No Undisclosed Events, Liabilities, Developments
or Circumstances. No event, liability, development or circumstance has occurred or exists with respect to the Company, its Subsidiaries or their respective business, properties, operations or financial condition, that would be required to be
disclosed by the Company under applicable securities laws on a registration statement on Form S-1 filed with the SEC relating to an issuance and sale by the Company of its Common Stock and which has not been publicly announced.

Subsidiaries is in violation of any term of or in default under its Certificate of Incorporation or Bylaws or their organizational charter or certificate of incorporation or bylaws, respectively. Neither the Company nor any of its Subsidiaries is in
violation of any judgment, decree or order or any statute, ordinance, rule or regulation applicable to the Company or its Subsidiaries, and neither the Company nor any of its Subsidiaries will conduct its business in violation of any of the
foregoing, except in all cases for possible violations which would not, individually or in the aggregate, have a Material Adverse Effect. Without limiting the generality of the foregoing, the Company is not in violation of any of the rules,
regulations or requirements of the Principal Market and has no knowledge of any facts or circumstances that would reasonably lead to delisting or suspension of the Common Stock by the Principal Market in the foreseeable future. During the two

has received no communication, written or oral, from the SEC or the Principal Market regarding the suspension or delisting of the Common Stock from the Principal Market. The Company and its Subsidiaries possess all certificates, authorizations and
permits issued by the appropriate regulatory authorities necessary to conduct their respective businesses, except where the failure to possess such certificates, authorizations or permits would not have, individually or in the aggregate, a Material
Adverse Effect, and neither the Company nor any such Subsidiary has received any notice of proceedings relating to the revocation or modification of any such certificate, authorization or permit. 
  
 (o) Foreign Corrupt Practices. Neither the Company

Company’s Certificate of Incorporation, as amended and as in effect on the date hereof (the “Certificate of Incorporation”), and the Company’s Bylaws, as amended and as in effect on the date hereof (the
“Bylaws”), and the terms of all securities convertible into, or exercisable or exchangeable for, shares of Common Stock and the material rights of the holders thereof in respect thereto. 
  
 (s) Indebtedness and Other Contracts. Neither the
Company nor any of its Subsidiaries (i) has any outstanding Indebtedness (as defined below), (ii) is in violation of any term of or in default under any contract, agreement or instrument relating to any Indebtedness, 

  

 - 11 - 








 
except where such violations and defaults would not result, individually or in the aggregate, in a Material Adverse Effect, or (iii) is a party to any
contract, agreement or instrument relating to any Indebtedness, the performance of which, in the judgment of the Company’s officers, has or is expected to have a Material Adverse Effect. Section 3(s) of the Schedule of Exceptions provides
a detailed description of the material terms of any such outstanding Indebtedness. For purposes of this Agreement: (x) “Indebtedness” of any Person means, any indebtedness, whether or not Contingent Obligations (as defined
below), (i) in respect of borrowed money (ii) evidenced by bonds, notes, debentures or similar instruments or letters of credit (or reimbursement agreements in respect thereof), (iii) in respect of capital lease obligations, and
(iv) all indebtedness created or arising under any conditional sale or other title retention agreement, or incurred as financing, in either case with respect to any property or assets acquired with the proceeds of such indebtedness (even though
the rights and remedies of the seller or bank under such agreement in the event of default are limited to repossession or sale of such property) including, without limitation, any indebtedness representing the balance deferred and unpaid of the
purchase price of any property, except any such balance that constitutes an accrued expense or trade payable, in the cases of (i) through (iv) if and only to the extent any of the preceding items would appear as a liability upon a balance
sheet prepared in accordance with GAAP. In addition, the term “Indebtedness” includes (i) all indebtedness of others secured by a lien on any asset of the Company or its Subsidiaries, measured by the lesser of the amount of such
indebtedness and the net book value of assets so encumbered and (ii) to the extent not otherwise included, the express guaranty of any indebtedness of any Person; (y) “Contingent Obligation” means, as to any Person, any
direct or indirect liability, contingent or otherwise, of that Person with respect to any indebtedness, lease, dividend or other obligation of another Person if the primary purpose or intent of the Person incurring such liability, or the primary
effect thereof, is to provide assurance to the obligee of such liability that such liability will be paid or discharged, or that any agreements relating thereto will be complied with, or that the holders of such liability will be protected (in whole
or in part) against loss with respect thereto; and (z) “Person” means an individual, a limited liability company, a partnership, a joint venture, a corporation, a trust, an unincorporated organization and a government or any
department or agency thereof. 
  
 (t) Absence
of Litigation. There is no action, suit, proceeding, inquiry or investigation before or by the Principal Market, any court, public board, government agency, self-regulatory organization or body pending or, to the knowledge of the Company,
threatened against or affecting the Company, the Common Stock or any of the Company’s Subsidiaries or any of the Company’s or its Subsidiaries’ officers or directors, that could, individually or in the aggregate, reasonably be
expected to result in a Material Adverse Effect. 
  
 (u) Insurance. The Company and each of its Subsidiaries are insured by insurers of recognized financial responsibility against such losses and risks and in such amounts as management of the Company believes to be prudent and
customary in the businesses in which the Company and its Subsidiaries are engaged. Neither the Company nor any such Subsidiary has been refused any insurance coverage sought or applied for and neither the Company nor any such 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 at a cost that would not have a
Material Adverse Effect. 
  

 - 12 - 








 (v) Employee Relations. (i) Neither Company nor any of its Subsidiaries is a
party to any collective bargaining agreement or employs any member of a union. The Company and its Subsidiaries believe that their relations with their employees are good. No executive officer of the Company or any of its Subsidiaries (as defined in
Rule 501(f) of the 1933 Act) has notified the Company or any such Subsidiary that such officer intends to leave the Company or any such Subsidiary or otherwise terminate such officer’s employment with the Company or any such Subsidiary. No
executive officer of the Company or any of its Subsidiaries, to the knowledge of the Company or any such Subsidiary, is in violation of any material term of any employment contract, confidentiality, disclosure or proprietary information agreement,
non-competition agreement, or any other contract or agreement or any restrictive covenant, and the continued employment of each such executive officer does not subject the Company or any such Subsidiary to any liability with respect to any of the
foregoing matters. 
  
 (ii) The Company and its
Subsidiaries are in compliance with all federal, state, local and foreign laws and regulations respecting labor, employment and employment practices and benefits, terms and conditions of employment and wages and hours, except where failure to be in
compliance would not, either individually or in the aggregate, reasonably be expected to result in a Material Adverse Effect. 
  
 (w) Title. The Company and its Subsidiaries have good and marketable title in fee simple to all real property and good and
marketable title to all personal property owned by them which is material to the business of the Company and its Subsidiaries, in each case free and clear of all liens, encumbrances and defects except such as do not materially affect the value of
such property and do not interfere with the use made and proposed to be made of such property by the Company and any of its Subsidiaries. Any real property and facilities held under lease by the Company and any of its Subsidiaries are held by them
under valid, subsisting and enforceable leases with such exceptions as are not material and do not interfere with the use made and proposed to be made of such property and buildings by the Company and its Subsidiaries. 
  
 (x) Intellectual Property Rights. The Company and its
Subsidiaries own or possess adequate rights or licenses to use all trademarks, trade names, service marks, service mark registrations, service names, patents, patent rights, copyrights, inventions, licenses, approvals, governmental authorizations,
trade secrets and other intellectual property rights (“Intellectual Property Rights”) necessary to conduct their respective businesses as now conducted except where the failure to so own or possess would not reasonably be expected
to result in a Material Adverse Effect. None of the Company’s Intellectual Property Rights have expired or terminated, or are expected to expire or terminate, within three years from the date of this Agreement. The Company does not have any
knowledge of any infringement by the Company or its Subsidiaries of Intellectual Property Rights of others. There is no claim, action or proceeding being made or brought, or to the knowledge of the Company, being threatened, against the Company or
its Subsidiaries regarding its Intellectual Property Rights. The Company is unaware of any facts or circumstances which might give rise to any of the foregoing infringements or claims, actions or proceedings. The Company and its Subsidiaries have
taken reasonable security measures to protect the secrecy, confidentiality and value of all of their intellectual properties. 
  

 - 13 - 








 (y) Environmental Laws. The Company and its Subsidiaries (i) are in
compliance with any and all Environmental Laws (as hereinafter defined), (ii) have received all permits, licenses or other approvals required of them under applicable Environmental Laws to conduct their respective businesses and (iii) are
in compliance with all terms and conditions of any such permit, license or approval where, in each of the foregoing clauses (i), (ii) and (iii), the failure to so comply could be reasonably expected to have, individually or in the aggregate, a
Material Adverse Effect. The term “Environmental Laws” means all federal, state, local or foreign laws relating to pollution or protection of human health or the environment (including, without limitation, ambient air, surface
water, groundwater, land surface or subsurface strata), including, without limitation, laws relating to emissions, discharges, releases or threatened releases of chemicals, pollutants, contaminants, or toxic or hazardous substances or wastes
(collectively, “Hazardous Materials”) into the environment, or otherwise relating to the manufacture, processing, distribution, use, treatment, storage, disposal, transport or handling of Hazardous Materials, as well as all
authorizations, codes, decrees, demands or demand letters, injunctions, judgments, licenses, notices or notice letters, orders, permits, plans or regulations issued, entered, promulgated or approved thereunder. 
  
 (z) Subsidiary Rights. The Company or one of its
Subsidiaries has the unrestricted right to vote, and (subject to limitations imposed by applicable law) to receive dividends and distributions on, all capital securities of its Subsidiaries as owned by the Company or such Subsidiary. 
  
 (aa) Investment Company. The Company is not, and is
not an affiliate of, an “investment company” within the meaning of the Investment Company Act of 1940, as amended. 
  
 (bb) Tax Status. The Company and each of its Subsidiaries (i) has made or filed all foreign, federal and state income and all
other 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 and (iii) has set aside on its books provision reasonably adequate for the payment of all taxes for periods subsequent to the periods to which such returns, reports or
declarations apply. There are no unpaid taxes in any material amount claimed to be due by the taxing authority of any jurisdiction, and the officers of the Company know of no basis for any such claim. 
  
 (cc) Internal Accounting and Disclosure Controls. The
Company maintains 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 generally accepted accounting principles and to maintain asset and liability accountability, (iii) access to assets or incurrence of liabilities is permitted
only in accordance with management’s general or specific authorization and (iv) the recorded accountability for assets and liabilities is compared with the existing assets and liabilities at reasonable intervals and appropriate action is
taken with respect to any difference. The Company maintains disclosure controls and procedures (as such term is defined in Rule 13a-14 under the 1934 Act) that are designed to ensure that information required to be disclosed by the Company in the
reports that it files or submits under the 1934 Act is recorded, processed, summarized and reported, within the time periods specified in the rules and forms of the SEC, including, without 

  

 - 14 - 








 
limitation, controls and procedures designed in to ensure that information required to be disclosed by the Company in the reports that it files or submits
under the 1934 Act is accumulated and communicated to the Company’s management, including its principal executive officer or officers and its principal financial officer or officers, as appropriate, to allow timely decisions regarding required
disclosure. Except as disclosed in the Company’s Form 10-K for the period ending December 31, 2004, which weaknesses have been corrected, during the twelve months prior to the date hereof neither the Company nor any of its Subsidiaries
have received any notice or correspondence from any accountant relating to any potential material weakness in any part of the system of internal accounting controls of the Company or any of its Subsidiaries. 
  
 (dd) Off Balance Sheet Arrangements. There is no
transaction, arrangement, or other relationship between the Company and an unconsolidated or other off balance sheet entity that is required to be disclosed by the Company in its Exchange Act filings and is not so disclosed or that otherwise would
be reasonably likely to have a Material Adverse Effect. 
  
 (ee) Ranking of Notes. No Indebtedness of the Company outstanding as of the date hereof is senior to or ranks pari passu with the Notes in right of payment, whether with respect of payment of
redemptions, interest, damages or upon liquidation or dissolution or otherwise. 
  
 (ff) Form S-3 Eligibility. The Company is eligible to register the Conversion Shares, the Warrant Shares and the Interest Shares
for resale by the Buyers using Form S-3 promulgated under the 1933 Act. 
  
 (gg) Manipulation of Price. The Company has not, and to its knowledge no one acting on its behalf has, (i) taken, directly or indirectly, any action designed to cause or to result in the stabilization or
manipulation of the price of any security of the Company to facilitate the sale or resale of any of the Securities, (ii) other than the Agent, sold, bid for, purchased, or paid any compensation for soliciting purchases of, any of the
Securities, or (iii) other than the Agent, paid or agreed to pay to any person any compensation for soliciting another to purchase any other securities of the Company. 
  
 (hh) Disclosure. The Company confirms that neither it nor any other Person acting on its behalf has
provided any of the Buyers or their agents or counsel with any information that constitutes or could reasonably be expected to constitute material, nonpublic information other than as set forth in the following sentence. The Company understands and
confirms that each of the Buyers will rely on the foregoing representations in effecting transactions in securities of the Company. All disclosure provided to the Buyers regarding the Company, its business and the transactions contemplated hereby,
including the Schedule of Exceptions, furnished by or on behalf of the Company is true and correct and does 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 the light of the circumstances under which they were made, not misleading. Each press release issued by the Company during the twelve (12) months preceding the date of this Agreement was, at the time of release, accurate in all
material respects.

states of the United States following the Closing Date.

Stock is then listed (subject to official notice of issuance) and shall maintain such listing of all Registrable Securities from time to time issuable under the terms of the Transaction Documents. The Company shall use reasonably best efforts to
maintain the Common Stocks’ authorization for quotation on the Principal Market. Neither the Company nor any of its Subsidiaries shall take any action which would be reasonably expected to result in the delisting or suspension of the Common
Stock on the Principal Market. The Company shall pay all fees and expenses in connection with satisfying its obligations under this Section 4(f).

Registration Rights Agreement) in connection with a bona fide margin agreement or other loan or financing arrangement that is secured by the Securities. The pledge of Securities shall not be deemed to be a transfer, sale or assignment of the
Securities hereunder, and no Investor effecting a pledge of Securities shall be required to provide the Company with any notice thereof or otherwise make any delivery to the Company pursuant to this Agreement or any other Transaction Document,
including, without limitation, Section 2(f) hereof; provided that an Investor and its pledgee shall be required to comply with the provisions of Section 2(f) hereof in order to effect a sale, transfer or assignment of Securities to such
pledgee. The Company hereby agrees to execute and deliver such documentation as a pledgee of the Securities may reasonably request in connection with a pledge of the Securities to such pledgee by an Investor.

 - 17 - 








 
Company shall file a Current Report on Form 8-K describing the terms of the transactions contemplated by the Transaction Documents in the form required by
the 1934 Act and attaching the material Transaction Documents (including, without limitation, this Agreement (and all schedules to this Agreement), the form of Notes, the form of Warrant and the Registration Rights Agreement) (including all
attachments, the “8-K Filing”). From and after the filing of the 8-K Filing with the SEC, the Company shall have disclosed any material nonpublic information delivered to the Buyers by the Company or any of its Subsidiaries, or any
of their respective officers, directors, employees or agents. The Company shall not, and shall cause each of its Subsidiaries and its and each of their respective officers, directors, employees and agents, not to, provide any Buyer with any
material, nonpublic information regarding the Company or any of its Subsidiaries from and after the filing of the 8-K Filing with the SEC without the express written consent of such Buyer. Except as otherwise set forth in the Registration Rights
Agreement, in the event of a breach of the foregoing covenant by the Company, or any of its Subsidiaries, or any of its or their respective officers, directors, employees and agents, in addition to any other remedy provided herein or in the
Transaction Documents, a Buyer shall notify the Company, and if the Company does not make public disclosure of such material nonpublic information within five (5) Business Days of such notification, such Buyer shall have the right to make a
public disclosure, in the form of a press release, public advertisement or otherwise, of such material, nonpublic information without the prior approval by the Company, its Subsidiaries, or any of its or their respective officers, directors,
employees or agents. No Buyer shall have any liability to the Company, its Subsidiaries, or any of its or their respective officers, directors, employees, stockholders or agents, for any such disclosure. Subject to the foregoing, neither the
Company, its Subsidiaries nor any Buyer shall issue any press releases or any other public statements with respect to the transactions contemplated hereby; provided, however, that the Company shall be entitled, without the prior
approval of any Buyer, to make any press release or other public disclosure with respect to such transactions (i) in substantial conformity with the 8-K Filings and contemporaneously therewith and (ii) as is required by applicable law and
regulations (provided that in the case of clause (i) each Buyer shall be consulted by the Company in connection with any such press release or other public disclosure prior to its release). Without the prior written consent of any applicable
Buyer, the Company shall not disclose the name of any Buyer in any filing, announcement, release or otherwise. 
  
 (i) Additional Notes; Variable Securities; Dilutive Issuances. For so long as any Notes or Warrants remain outstanding, the Company
shall not, in any manner, issue or sell any rights, warrants or options to subscribe for or purchase Common Stock or directly or indirectly convertible into or exchangeable or exercisable for Common Stock at a conversion, exchange or exercise price
which varies or may vary after issuance with the market price of the Common Stock, including by way of one or more reset(s) to any fixed price unless the conversion, exchange or exercise price of any such security cannot be less than the then
applicable Conversion Price (as defined in the Notes) with respect to the Common Stock into which any Note is convertible or the then applicable Exercise Price (as defined in the Warrants) with respect to the Common Stock into which any Warrant is
exercisable. For purposes of clarification, this does not prohibit the issuance of securities with customary “weighted average” or “full ratchet” anti-dilution adjustments which adjust a fixed conversion or exercise price of
securities sold by the Company in the future. For so long as any Notes or Warrants remain outstanding, the Company shall not, in any manner, enter into or affect any Dilutive Issuance (as defined in the Notes) if the effect of such Dilutive Issuance
is to cause the Company to be 

  

 - 18 - 








 
required to issue upon conversion of any Note or exercise of any Warrant any shares of Common Stock in excess of that number of shares of Common Stock which
the Company may issue upon conversion of the Notes and exercise of the Warrants without breaching the Company’s obligations under the rules or regulations of the Principal Market. 
  
 (j) Conduct of Business. The business of the Company and its Subsidiaries shall not be conducted in
violation of any law, ordinance or regulation of any governmental entity, except where such violations would not result, either individually or in the aggregate, in a Material Adverse Effect. 
  
 (k) Additional Issuances of Securities. 
  
 (i) For purposes of this Section 4(k), the following
definitions shall apply. 
  
 (1)
“Convertible Securities” means any stock or securities (other than Options) convertible into or exercisable or exchangeable for shares of Common Stock. 
  
 (2) “Options” means any rights, warrants or options to subscribe for or purchase shares of
Common Stock or Convertible Securities. 
  
 (3)
“Common Stock Equivalents” means, collectively, Options and Convertible Securities. 
  
 (ii) From the date hereof until ninety (90) days after the Effective Date (as defined in the Registration Rights Agreement) the Company
will not, directly or indirectly, file any registration statement with the SEC other than the Registration Statement (as defined in the Registration Rights Agreement). From the date hereof until the Effective Date, the Company will not, directly or
indirectly, offer, sell, grant any option to purchase, or otherwise dispose of (or announce any offer, sale, grant or any option to purchase or other disposition of) any of its or its Subsidiaries’ equity or equity equivalent securities,
including without limitation any debt, preferred stock or other instrument or security that is, at any time during its life and under any circumstances, convertible into or exchangeable or exercisable for shares of Common Stock or Common Stock
Equivalents (any such offer, sale, grant, disposition or announcement being referred to as a “Subsequent Placement”). 
  
 (iii) From the Closing Date until the date twelve months after the Closing Date, the Company will not, directly or indirectly, effect any
Subsequent Placement unless the Company shall have first complied with this Section 4(k)(iii). 
  
 (1) The Company shall deliver to each Buyer a written notice (the “Offer Notice”) of any proposed or intended
issuance or sale or exchange (the “Offer”) of the securities being offered (the “Offered Securities”) in a Subsequent Placement, which Offer Notice shall (w) identify and describe the Offered Securities,
(x) describe the price and other terms upon which they are to be issued, sold or exchanged, and the number or amount of the Offered Securities to be issued, sold or exchanged, and (y) offer to issue and sell to or exchange with such Buyers
at least 30% of 

  

 - 19 - 








 
the Offered Securities, allocated among such Buyers (a) based on such Buyer’s pro rata portion of the aggregate principal amount of Notes purchased
hereunder (the “Basic Amount”), and (b) with respect to each Buyer that elects to purchase its Basic Amount, any additional portion of the Offered Securities attributable to the Basic Amounts of other Buyers as such Buyer shall
indicate it will purchase or acquire should the other Buyers subscribe for less than their Basic Amounts (the “Undersubscription Amount”). 
  
 (2) To accept an Offer, in whole or in part, such Buyer must deliver a written notice to the Company prior to the end of the tenth
(10th) Business Day after such Buyer’s receipt of the Offer Notice (the “Offer Period”),
setting forth the portion of such Buyer’s Basic Amount that such Buyer elects to purchase and, if such Buyer shall elect to purchase all of its Basic Amount, the Undersubscription Amount, if any, that such Buyer elects to purchase (in either
case, the “Notice of Acceptance”). If the Basic Amounts subscribed for by all Buyers are less than the total of all of the Basic Amounts, then each Buyer who has set forth an Undersubscription Amount in its Notice of Acceptance
shall be entitled to purchase, in addition to the Basic Amounts subscribed for, the Undersubscription Amount it has subscribed for; provided, however, that if the Undersubscription Amounts subscribed for exceed the difference between
the total of all the Basic Amounts and the Basic Amounts subscribed for (the “Available Undersubscription Amount”), each Buyer who has subscribed for any Undersubscription Amount shall be entitled to purchase only that portion of
the Available Undersubscription Amount as the Basic Amount of such Buyer bears to the total Basic Amounts of all Buyers that have subscribed for Undersubscription Amounts, subject to rounding by the Company to the extent its deems reasonably
necessary. 
  
 (3) The Company shall have thirty
(30) days from the expiration of the Offer Period above to offer, issue, sell or exchange all or any part of such Offered Securities as to which a Notice of Acceptance has not been given by the Buyers (the “Refused
Securities”), but only upon terms and conditions (including, without limitation, unit prices and interest rates) that are not more favorable to the acquiring person or persons or less favorable to the Company than those set forth in the
Offer Notice. 
  
 (4) Upon the closing of the
issuance, sale or exchange of all or less than all of the Refused Securities, the Buyers shall acquire from the Company, and the Company shall issue to the Buyers, the number or amount of Offered Securities specified in the Notices of Acceptance, as
reduced pursuant to Section 4(k)(iii)(3) above if the Buyers have so elected, upon the terms and conditions specified in the Offer. Without in any way limiting the ability of the Company to complete transactions with other purchasers of Offered
Securities, the purchase by the Buyers of any Offered Securities is subject in all cases to the preparation, execution and delivery by the Company and the Buyers of a purchase agreement relating to such Offered Securities reasonably satisfactory in
form and substance to the Buyers and their respective counsel. 
  
 (5) Any Offered Securities not acquired by the Buyers or other persons in accordance with Section 4(k)(iii)(3) above may not be issued, sold or 

  

 - 20 - 








 
exchanged until they are again offered to the Buyers under the procedures specified in this Agreement. 
  
 (iv) The restrictions contained in subsections (ii) and
(iii) of this Section 4(k) shall not apply in connection with the issuance of any Excluded Securities (as defined in the Notes) or any security issued in a bona fide underwritten public offering by the Company or any of its Subsidiaries.

  
 5. REGISTER; TRANSFER AGENT INSTRUCTIONS. 
  
 (a) Register. The Company shall maintain at its
principal executive offices (or such other office or agency of the Company as it may designate by notice to each holder of Securities), a register for the Notes and the Warrants in which the Company shall record the name and address of the Person in
whose name the Notes and the Warrants have been issued (including the name and address of each transferee), the principal amount of Notes held by such Person, the number of Conversion Shares issuable upon conversion of the Notes and Warrant Shares
issuable upon exercise of the Warrants held by such Person. The Company shall keep the register open and available at all times during business hours for inspection of any Buyer or its legal representatives. 
  
 (b) Transfer Agent Instructions. The Company shall
issue irrevocable instructions to its transfer agent, and any subsequent transfer agent, to issue certificates or credit shares to the applicable balance accounts at The Depository Trust Company (“DTC”), registered in the name of
each Buyer or its respective nominee(s), for the Conversion Shares, the Interest Shares, if any, and the Warrant Shares in such amounts as specified from time to time by each Buyer to the Company upon conversion of the Notes or exercise of the
Warrants in the form of Exhibit D attached hereto (the “Irrevocable Transfer Agent Instructions”). The Company warrants that no instruction other than the Irrevocable Transfer Agent Instructions referred to in this
Section 5(b), and stop transfer instructions to give effect to Section 2(g) hereof, will be given by the Company to its transfer agent with respect to the Securities, and that the Securities shall otherwise be freely transferable on the
books and records of the Company, as applicable, and to the extent provided in this Agreement and the other Transaction Documents. If a Buyer effects a sale, assignment or transfer of the Securities in accordance with Section 2(g), the Company
shall permit the transfer and shall promptly instruct its transfer agent to issue one or more certificates or credit shares to the applicable balance accounts at DTC in such name and in such denominations as specified by such Buyer to effect such
sale, transfer or assignment. In the event that such sale, assignment or transfer involves Conversion Shares, Interest Shares, Warrant Shares sold, assigned or transferred pursuant to an effective registration statement or pursuant to Rule 144, the
transfer agent shall issue such Securities to the Buyer, assignee or transferee, as the case may be, without any restrictive legend. The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to a Buyer.
Accordingly, the Company acknowledges that the remedy at law for a breach of its obligations under this Section 5(b) will be inadequate and agrees, in the event of a breach or threatened breach by the Company of the provisions of this
Section 5(b), that a Buyer shall be entitled, in addition to all other available remedies, to an order and/or injunction restraining any breach and requiring immediate issuance and transfer, without the necessity of showing economic loss and
without any bond or other security being required.

condition(s)), the nonbreaching party shall have the option to terminate this Agreement with respect to such breaching party at the close of business on such date without liability of any party to any other party; provided, however, this if this
Agreement is terminated pursuant to this Section 8, the Company shall remain obligated to reimburse the non-breaching Buyers for the expenses described in Section 4(g) above. 
  
 9. MISCELLANEOUS. 
  
 (a) Governing Law; Jurisdiction; Jury Trial. All questions concerning the construction, validity, enforcement and interpretation of
this Agreement shall be governed by the internal laws of the State of New York, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of New York or any other jurisdictions) that would cause the
application of the laws of any jurisdictions other than the State of New York. Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in The City of New York, Borough of Manhattan, for the
adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not
personally subject to the jurisdiction of any such court, that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such suit, action or proceeding is improper. Each party hereby irrevocably waives personal
service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof to such party at the address for such notices to it under this Agreement and agrees that such service shall constitute good and
sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. EACH PARTY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE, AND AGREES NOT
TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION WITH OR ARISING OUT OF THIS AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREBY.  
  
 (b) Counterparts. This Agreement may be executed in two or more identical counterparts, all of which
shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party; provided that a facsimile signature shall be considered due execution and shall be binding
upon the signatory thereto with the same force and effect as if the signature were an original, not a facsimile signature. 
  
 (c) Headings. The headings of this Agreement are for convenience of reference and shall not form part of, or affect the
interpretation of, this Agreement. 
  
 (d)
Severability. If any provision of this Agreement shall be invalid or unenforceable in any jurisdiction, such invalidity or unenforceability shall not affect the validity or enforceability of the remainder of this Agreement in that

 (e) Entire Agreement; Amendments. This Agreement and the other Transaction
Documents supersede all other prior oral or written agreements between the Buyers, the Company, their Affiliates and Persons acting on their behalf with respect to the matters discussed herein, and this Agreement, the other Transaction Documents and
the instruments referenced herein and therein contain the entire understanding of the parties with respect to the matters covered herein and therein and, except as specifically set forth herein or therein, neither the Company nor any Buyer makes any
representation, warranty, covenant or undertaking with respect to such matters. No provision of this Agreement may be amended other than by an instrument in writing signed by the Company and the holders of at least a majority of the aggregate number
of Registrable Securities issued and issuable hereunder, and any amendment to this Agreement made in conformity with the provisions of this Section 9(e) shall be binding on all Buyers and holders of Securities, as applicable. No provision
hereof may be waived other than by an instrument in writing signed by the party against whom enforcement is sought. No such amendment shall be effective to the extent that it applies to less than all of the holders of the applicable Securities then
outstanding. No consideration shall be offered or paid to any Person to amend or consent to a waiver or modification of any provision of any of the Transaction Documents unless the same consideration also is offered to all of the parties to the
Transaction Documents, holders of Notes or holders of the Warrants, as the case may be. The Company has not, directly or indirectly, made any agreements with any Buyers relating to the terms or conditions of the transactions contemplated by the
Transaction Documents except as set forth in the Transaction Documents. 
  
 (f) Notices. Any notices, consents, waivers or other communications required or permitted to be given under the terms of this Agreement must be in writing and will be deemed to have been delivered:

 (g)
Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their respective successors and assigns, including any purchasers of the Notes or the Warrants. The Company shall not assign this
Agreement or any rights or obligations hereunder without the prior written consent of the holders of at least a majority of the aggregate number of Registrable Securities issued and issuable hereunder, including by way of a Fundamental Transaction
(unless the Company is in compliance with the applicable provisions governing Fundamental Transactions set forth in the Notes and the Warrants). A Buyer may assign some or all of its rights hereunder in connection with transfer of any of its
Securities 

  

 - 26 - 








 
without the consent of the Company, in which event such assignee shall be deemed to be a Buyer hereunder with respect to such assigned rights. 
  
 (h) No Third Party Beneficiaries. This Agreement is
intended for the benefit of the parties hereto and their respective permitted successors and assigns, and is not for the benefit of, nor may any provision hereof be enforced by, any other Person. 
  
 (i) Survival. Unless this Agreement is terminated
under Section 8, the representations and warranties of the Company and the Buyers contained in Sections 2 and 3 and the agreements and covenants set forth in Sections 4, 5 and 9 shall survive the Closing. Each Buyer shall be responsible only
for its own representations, warranties, agreements and covenants hereunder. 
  
 (j) Further Assurances. Each party shall do and perform, or cause to be done and performed, all such further acts and things, and shall execute and deliver all such other agreements, certificates, instruments
and documents, as any other party may reasonably request in order to carry out the intent and accomplish the purposes of this Agreement and the consummation of the transactions contemplated hereby. 
  
 (k) Indemnification. In consideration of each
Buyer’s execution and delivery of the Transaction Documents and acquiring the Securities thereunder and in addition to all of the Company’s other obligations under the Transaction Documents, the Company shall defend, protect, indemnify and
hold harmless each Buyer and each other holder of the Securities and all of their stockholders, partners, members, officers, directors, employees and direct or indirect investors and any of the foregoing Persons’ agents or other representatives
(including, without limitation, those retained in connection with the transactions contemplated by this Agreement) (collectively, the “Indemnitees”) from and against any and all actions, causes of action, suits, claims, losses,
costs, penalties, fees, liabilities and damages, and expenses in connection therewith (irrespective of whether any such Indemnitee is a party to the action for which indemnification hereunder is sought), and including reasonable attorneys’ fees
and disbursements (the “Indemnified Liabilities”), incurred by any Indemnitee as a result of, or arising out of, or relating to (a) any misrepresentation or breach of any representation or warranty made by the Company in the
Transaction Documents or any other certificate, instrument or document contemplated hereby or thereby, (b) any breach of any covenant, agreement or obligation of the Company contained in the Transaction Documents or any other certificate,
instrument or document contemplated hereby or thereby or (c) any cause of action, suit or claim brought or made against such Indemnitee by a third party (including for these purposes a derivative action brought on behalf of the Company) and
arising out of or resulting from (i) the execution, delivery, performance or enforcement of the Transaction Documents or any other certificate, instrument or document contemplated hereby or thereby, (ii) any transaction financed or to be
financed in whole or in part, directly or indirectly, with the proceeds of the issuance of the Securities, (iii) any disclosure made by such Buyer pursuant to Section 4(i), or (iv) the status of such Buyer or holder of the Securities
as an investor in the Company pursuant to the transactions contemplated by the Transaction Documents. To the extent that the foregoing undertaking by the Company may be unenforceable for any reason, the Company shall make the maximum contribution to
the payment and satisfaction of each of the Indemnified Liabilities which is permissible under applicable law. Except as otherwise set forth herein, the mechanics and 

  

 - 27 - 








 
procedures with respect to the rights and obligations under this Section 9(k) shall be the same as those set forth in Section 6 of the Registration
Rights Agreement. 
  
 (l) No Strict
Construction. The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent. 
  
 (m) Remedies. Each Buyer and each holder of the Securities shall have all rights and remedies set forth in the Transaction
Documents and all rights and remedies which such holders have been granted at any time under any other agreement or contract and all of the rights which such holders have under any law. Any Person having any rights under any provision of this
Agreement shall be entitled to enforce such rights specifically (without posting a bond or other security), to recover damages by reason of any breach of any provision of this Agreement and to exercise all other rights granted by law. Furthermore,
the Company recognizes that in the event that it fails to perform, observe, or discharge any or all of its obligations under the Transaction Documents, any remedy at law may prove to be inadequate relief to the Buyers. The Company therefore agrees
that the Buyers shall be entitled to seek temporary and permanent injunctive relief in any such case without the necessity of proving actual damages and without posting a bond or other security. 
  
 (n) Payment Set Aside. To the extent that the Company
makes a payment or payments to the Buyers hereunder or pursuant to any of the other Transaction Documents or the Buyers enforce or exercise their rights hereunder or thereunder, and such payment or payments or the proceeds of such enforcement or
exercise or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the Company, a trustee, receiver or any
other Person under any law (including, without limitation, any bankruptcy law, foreign, state or federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to
be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred. 
  
 (o) Independent Nature of Buyers’ Obligations and Rights. The obligations of each Buyer under any Transaction Document are
several and not joint with the obligations of any other Buyer, and no Buyer shall be responsible in any way for the performance of the obligations of any other Buyer under any Transaction Document. Nothing contained herein or in any other
Transaction Document, and no action taken by any Buyer pursuant hereto or thereto, shall be deemed to constitute the Buyers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Buyers are in
any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Documents and the Company acknowledges that the Buyers are not acting in concert or as a group with respect to such
obligations or the transactions contemplated by the Transaction Documents. Each Buyer confirms that it has independently participated in the negotiation of the transaction contemplated hereby with the advice of its own counsel and advisors. Each
Buyer shall be entitled to independently protect and enforce its rights, including, without limitation, the rights arising out of this Agreement or out of any other Transaction Documents, and it shall not be necessary for any other Buyer to be
joined as an additional party in any proceeding for such purpose.
