For purposes of this Agreement, the term “Knowledge” means, with respect to each party, the

reasonable knowledge of the individuals respectively indicated on Exhibit F hereto, after and/or assuming due inquiry.

     Section 2.6 SEC Filings. The Company has filed all periodic reports (including exhibits and all other information incorporated by reference) required to be filed by it with the SEC since December 31, 2005 (such reports, as respectively amended since the time of their respective filings, “Company SEC Reports”). The Company SEC Reports (a) were prepared in accordance with, and complied in all material respects with, the requirements of the Exchange Act and the rules and regulations promulgated thereunder applicable to such Company SEC Reports, and (b) did not at the time they were filed contain any untrue statement of a material fact or omit 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, except in the case of each of the preceding clauses (a) and (b) to the extent corrected on or prior to the date of this Agreement, by the filing of the applicable amending or superseding Company SEC Reports.

any commitment to become a party to, any “off-balance sheet arrangements” (as defined in Item 303(a) of Regulation S-K of the SEC).

     Section 2.8 Internal Controls. The Company has established and maintains a system of internal controls over financial reporting required by Rules 13a-15(f) or 15d-15(f) under the Exchange Act designed to provide reasonable assurances regarding the reliability of financial reporting and the preparation of its consolidated financial statements in accordance with GAAP and including those policies and procedures that: (a) require the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company and its subsidiaries; (b) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that receipts and expenditures of the Company and its subsidiaries are being made only in accordance with authorizations of management and the Company’s board of directors; and (c) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the assets of the Company and its subsidiaries that could have a material effect on Company’s financial statements, including, without limitation, the Company Financials. There are no “material weaknesses” (as defined by the Public Company Accounting Oversight Board) in the design or operation of the Company’s internal controls, and there is no series of multiple “significant deficiencies” (as defined by the Public Company Accounting Oversight Board) that collectively represent a “material weakness” in the design or operation of Parent’s internal controls. Since March 31, 2008 neither the Company nor any of its subsidiaries (including any current employee or service provider thereof) nor, to the Company’s Knowledge, the Company’s independent auditors have identified or been made aware of (a) any significant deficiency or material weakness in the system of internal controls utilized by the Company and its subsidiaries, (b) any fraud, whether or not material, that involves the Company’s management or other employees who have a role in the preparation of financial statements or the internal controls utilized by the Company and its subsidiaries or (c) any material claim or allegation regarding any of the foregoing.

     Section 2.9 Absence of Certain Changes or Events

          (a) Since the date of the Company Balance Sheet, the business of the Company and its subsidiaries has been conducted in the ordinary course consistent with past practices and there has not been, accrued or arisen any event, change or development that has had or could reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect.

          (b) Since the date of the Company Balance Sheet through the date of this Agreement, the Company’s board of directors has not authorized or taken any action to authorize and the Company has not taken any other steps or action, and no other event, change or development has occurred that, if occurring after the filing of the Certificate of Designation and the issuance of the Preferred Shares would, pursuant to the Certificate of Designation or applicable law, (i) require the vote of the holders of the Preferred Shares, (ii) require or permit the conversion of the Preferred Shares, or (iii) require or permit any adjustment in the number of Preferred Shares or the number of Common Shares issuable upon conversion thereof.

          (c) Since the date of the Company Balance Sheet, the Company’s board of directors has not authorized or taken any action to authorize any amendments to the Company’s certificate of incorporation or by-laws.

     Section 2.10 Validity of the Shares. The Preferred Shares to be issued pursuant to this Agreement and the shares of Common Stock that may be issued upon conversion thereof will, as of the date hereof and as of the date of issue of any such Common Stock, when issued in accordance with the terms hereof and of the Certificate of Designation, be duly authorized, validly issued, fully paid and non-assessable, with the holder being entitled to all rights accorded to a holder thereof pursuant to this Agreement, the Company’s certificate of incorporation, the Company’s by-laws and the Certificate of Designation and the Associated Agreements, as the case may be, and are free from all preemptive or similar rights, taxes, liens and charges with respect to the issue thereof, whether created by statute, the Company’s certificate of incorporation or by-laws or any agreement to which the Company is a party or by which it or any of its assets or property is bound.

     Section 2.11 No Registration Rights. Other than as disclosed in the Company SEC Reports, there are no outstanding rights which permit the holder thereof to cause the Company to file a registration statement under the Securities Act or which permit the holder thereof to include securities of the Company in a registration statement filed by the Company under the Securities Act, and there are no outstanding agreements or other commitments which otherwise relate to the registration of any securities of the Company under the Securities Act.

     Section 2.12 NASDAQ Filings. The Company has duly and timely filed with the NASDAQ Global Select Market, in accordance with the rules and regulations of the NASDAQ Global Select Market, a Notification of Listing of Additional Shares (or such other form as may be required by the NASDAQ Global Select Market) with respect to the proposed issuance of the Preferred Shares contemplated by this Agreement.

     Section 2.13 Investment Company Act. The Company is not and, after giving effect to the offering and sale of the Preferred Shares and the application of the proceeds thereof as described in this Agreement will not be an “investment company” as defined in the United States Investment Company Act of 1940 (the “Investment Company Act”).

     Section 2.14 No General Solicitation; Private Offering. Neither the Company, nor any of its subsidiaries, nor any person acting on its or their behalf, has engaged or will engage in any form of general solicitation or general advertising (within the meaning of Regulation D under the Securities Act) in connection with the offer or sale of the Preferred Shares or in any other action (including any offering of any securities of the Company under circumstances which would require the integration of such offering with the offering of the Preferred Shares under the Securities Act) which might subject the offering, issuance or sale of the Preferred Shares to the registration requirements of Section 5 of the Securities Act.
