The Company has no knowledge of any federal, state or other governmental tax deficiency, penalty or assessment which has been or might be asserted or threatened against it which would reasonably be expected to have a Material Adverse Effect.
2.18      Intellectual Property. The Company and the Subsidiaries own or possess adequate enforceable rights to use all patents, patent applications, trademarks (both registered and unregistered), service marks, trade names, trademark registrations, service mark registrations, copyrights, licenses and know-how (including trade secrets and other unpatented and/or unpatentable proprietary or confidential information, systems or procedures) (collectively, the “Intellectual Property”), necessary for the conduct of their respective businesses as conducted as of the date of this Agreement, except to the extent that the failure to own or possess adequate rights to use such Intellectual Property would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect; the Company and the Subsidiaries have not received any written notice of any claim of infringement or conflict which asserted Intellectual Property rights of others, which infringement or conflict, if the subject of an unfavorable decision, would reasonably be expected to result in a Material Adverse Effect; there are no pending, or to the Company’s knowledge, threatened judicial proceedings or interference proceedings against the Company or its Subsidiaries challenging the Company’s or any of its Subsidiary’s rights in or to or the validity of the scope of any of the Company’s or any Subsidiary’s patents, patent applications or proprietary information, except for such right or claim that would not, individually or in the aggregate, reasonably be expected to result in a Material Adverse Effect; to the Company’s knowledge no other entity or individual has any right or claim in any of the Company’s or any of its Subsidiary’s patents, patent applications or any patent to be issued therefrom by virtue of any contract, license or other agreement entered into between such entity or individual and the Company or any Subsidiary or by any non-contractual obligation, other than by written licenses granted by the Company or any Subsidiary, except for such right or claim that would not, individually or in the aggregate, reasonably be expected to result in a Material Adverse Effect; the Company and the Subsidiaries have not received any written notice of any claim challenging the rights of the Company or its Subsidiaries in or to any Intellectual Property owned, licensed or optioned by the Company or any Subsidiary which claim, if the subject of an unfavorable decision, would reasonably be expected to result in a Material Adverse Effect. 
2.19      Disclosure Controls. The Company maintains systems of internal accounting controls designed to provide reasonable assurance that (a) transactions are executed in accordance 

10

with management’s general or specific authorizations; (b) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to maintain asset accountability; (c) access to assets is permitted only in accordance with management’s general or specific authorization; and (d) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences. Except as disclosed in the SEC Reports, the Company is not aware of any material weakness in its internal control over financial reporting. Since the date of the latest audited financial statements of the Company included within the SEC Reports, there has been no change in the Company’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting. The Company has established disclosure controls and procedures (as defined in Exchange Act Rules 13a-15 and 15d-15) for the Company and designed such disclosure controls and procedures to ensure that material information relating to the Company and the Subsidiaries is made known to the certifying officers by others within those entities, particularly during the period in which the Company’s Annual Report on Form 10-K or Quarterly Report on Form 10-Q, as the case may be, is being prepared. The Company’s certifying officers have evaluated the effectiveness of the Company’s controls and procedures as of a date within 90 days prior to the filing date of the Annual Report on Form 10-K for the fiscal year most recently ended (such date, the “Evaluation Date”). The Company presented in its Annual Report on Form 10-K for the fiscal year most recently ended the conclusions of the certifying officers about the effectiveness of the disclosure controls and procedures based on their evaluations as of the most recent Evaluation Date. Since the most recent Evaluation Date, there have been no significant changes in the Company’s internal controls (as such term is defined in Item 307(b) of Regulation S-K under the Securities Act) or, to the Company’s knowledge, in other factors that would significantly adversely affect the Company’s internal controls. 
2.20      No “Bad Actor” Disqualifying Events.  No “Bad Actor” disqualifying event described in Rule 506(d)(1)(i) to (viii) of the Securities Act (a “Disqualification Event”) is applicable to the Company, except for a Disqualification Event as to which Rule 506(d)(2)(ii–iv) or (d)(3), is applicable; provided that, for purposes of this representation and warranty, the Company relied exclusively on completed and executed questionnaires delivered to the Company by its directors and executive officers and beneficial owners of twenty percent (20%) or more of the Company’s outstanding voting equity securities. 
2.21      Environmental Laws. The Company (i) is in compliance with any and all Environmental Laws (as hereinafter defined), (ii) has received all permits, licenses or other approvals required of it under applicable Environmental Laws to conduct its business and (iii) is in compliance with all terms and conditions of any such permit, license or approval except where, in each of the foregoing clauses (i), (ii) and (iii), the failure to so comply would reasonably be expected to result in 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 

11

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.
2.22      Foreign Corrupt Practices Act.  None of the Company, the Subsidiaries, or, to the knowledge of the Company, any agent or other person acting in the course of its actions on behalf of the Company or the Subsidiaries, has, directly or indirectly, (i) used any corporate funds, or will use any proceeds from the sale of the Securities, for unlawful contributions, gifts, entertainment or other unlawful expenses related to foreign or domestic political activity, (ii) made any unlawful influence payment to foreign or domestic government officials or to any foreign or domestic political parties or campaigns from corporate funds, or (iii) violated in any material respect any provision of the Foreign Corrupt Practices Act of 1977, as amended, and the rules and regulations thereunder which was or is applicable to the Company or any of the Subsidiaries.
2.23      Compliance with Anti-Money Laundering Laws. The operations of the Company are and have been conducted at all times in compliance with applicable financial recordkeeping and reporting requirements and all other applicable U.S. and non-U.S. anti-money laundering laws and regulations, including, but not limited to, those of the Currency and Foreign Transactions Reporting Act of 1970, as amended, the USA Patriot Act of 2001 and the applicable money laundering statutes of all applicable jurisdictions, the rules and regulations thereunder and any related or similar rules, regulations or guidelines, issued, administered or enforced by any governmental agency (collectively, the “Anti-Money Laundering Laws”), the Company has in place policies and procedures reasonably designed to ensure that its and its Subsidiaries’, if any, operations will continue to be conducted in compliance with all applicable Money Laundering Laws and no action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator involving the Company or the Subsidiaries with respect to the Anti-Money Laundering Laws is pending or, to the knowledge of the Company, threatened.
2.24      Sarbanes-Oxley Act. The Company is in compliance in all material respects with any and all applicable requirements of the Sarbanes-Oxley Act of 2002, as amended, that are effective as of the date hereof, and any and all applicable rules and regulations promulgated by the SEC thereunder that are effective as of the date hereof.
2.25      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, interested stockholder, business combination, poison pill (including any distribution under a rights agreement) or other similar anti-takeover provision under the Certificate of Incorporation, Bylaws or other organizational documents or the laws of the jurisdiction of its formation which is or could become applicable to any Purchaser as a result of the transactions contemplated by this Agreement, including, without limitation, the Company’s issuance of the Securities and any Purchaser’s ownership of the Securities. 
2.26      Insurance. The Company is 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 business in which the Company is engaged. The Company has not been refused any insurance coverage sought or applied for, the refusal of which would reasonably 

12

be expected to have a Material Adverse Effect. The Company has no 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 reasonably be expected to have a Material Adverse Effect.
2.27      Title. The Company has marketable title to all personal property owned by it which is material to the business of the Company, in each case free and clear of all Liens except for Liens which 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. Any real property and facilities held under material lease by the Company are held by it under valid and enforceable leases with such exceptions as are not material and do not materially interfere with the use made and proposed to be made of such property and buildings by the Company.
2.28      Third Party Indebtedness. Other than the Existing Convertible Notes and indebtedness incurred in the ordinary course of business, the Company does not have any indebtedness for borrowed money that is owed to a third party.

Section 13.      Fees and Expenses.  Except as otherwise provided in this Agreement, all expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party incurring such expenses; provided, however, that in the event the Closing does not occur solely due to the failure by the Company to obtain the written confirmation from Nasdaq as contemplated by Section 5.4, then the Company shall reimburse the Purchasers for their actual, reasonable and documented expenses incurred in connection with the transactions contemplated by this Agreement in an amount not to exceed an aggregate of $30,000.
Section 14.      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 jurisdiction or the validity or enforceability of any provision of this Agreement in any other jurisdiction.
Section 15.      Entire Agreement; Amendments.  This Agreement supersedes all other prior oral or written agreements between the Purchasers, the Company, their Affiliates and persons acting on their behalf with respect to the matters discussed herein, and this Agreement, the Notes, the Warrants and the instruments referenced herein 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, none of the Company or any of the Purchasers makes any representation, warranty, covenant or undertaking with respect to such matters.  No provision of this Agreement may be amended, waived or modified other than by an instrument in writing signed by the Company and: (a) prior to the Closing, the Purchasers purchasing at least a majority of the aggregate principal amount of the 

20

Notes, as set forth on SCHEDULE A hereto, or (b) after the Closing, the Purchasers holding at least a majority of the aggregate principal amount of the then-outstanding Notes.  Any such amendment, waiver or modification effected in accordance with this Section 15 shall be binding upon all Purchasers and each transferee of the Securities (or the Note Shares or Warrant Shares), each future holder of all such securities and the Company.

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: (a) upon receipt, when delivered personally; (b) upon receipt, when sent by e-mail (provided confirmation of transmission is mechanically or electronically generated and kept on file by the sending party); or (c) one calendar day (excluding Saturdays, Sundays, and national banking holidays in the United States) after deposit with an overnight courier service, in each case properly addressed to the party to receive the same.
