ARTICLE 5. BORROWER’S REPRESENTATIONS AND WARRANTIES .

To induce the Lender to enter into this Agreement and to extend the Revolving Loan to Borrower and to issue Letters of Credit, Borrower, jointly and severally, makes the following representations and warranties to the Lender:

5.1 Corporate Authority; Subsidiaries . Borrower and each of its Subsidiaries (i) is a corporation or limited liability company duly organized, validly existing, and in good standing under the laws of its State of organization, (ii) is qualified to do business as a foreign corporation and is in good standing in all jurisdictions where its activities or ownership of property require such qualification,

-16-

except for any such failure to be so qualified which may reasonably be expected to result in a Material Adverse Change, and (iii) has the full and unrestricted power and authority, corporate and otherwise, to own, operate and lease its properties, to carry on its business as currently conducted, to execute and deliver and perform the Loan Documents to which it is a party, to incur the obligations provided for herein and therein, and to perform the transactions contemplated hereby and thereby, all of which have been duly and validly authorized by all proper and necessary action (all of which actions are in full force and effect). Except as set forth in Schedule 4.1 hereof, Borrower has no Subsidiaries.

5.2 Approvals . Borrower has provided Lender with a true and accurate certificate of the resolutions adopted by its governing body authorizing the loan transactions contemplated by this Agreement. No further approval, consent, notice to or other action by any other Person (including, without limitation, the stockholders or other equity holders of Borrower or any of its Subsidiaries or any Governmental Authority) is or will be necessary to permit the valid execution, delivery or performance by Borrower of this Agreement or any of the other Loan Documents.

5.3 Binding Effect, No Violations . Each of the Loan Documents, upon its execution and delivery, will constitute a legal, valid and binding obligation of Borrower and its Subsidiaries party thereto, enforceable against Borrower and its Subsidiaries in accordance with its terms, except as may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ rights generally and by general principles of equity (regardless of whether enforcement is sought in a proceeding in equity or at law). The execution, delivery and performance of the Loan Documents will not (i) violate, conflict with or constitute a default (with due notice, lapse of time or both) under any law, regulation, order or any other requirement of any court, tribunal, arbitrator or other Governmental Authority, any terms of the Governance Documents of Borrower or any of its Subsidiaries, or any contract, agreement or other arrangement binding upon or affecting Borrower or any of its Subsidiaries or any of their respective properties, or (ii) result in the creation, imposition or acceleration of any indebtedness or any Encumbrance of any nature upon, or with respect to, Borrower or any of its Subsidiaries or any of their respective properties.

5.4 Litigation . Without limiting Borrower’s representation and warranty in Section 5.21 hereof, except as previously disclosed to the Lender in writing or in filings made by Borrower with the SEC, there is no judgment, order, claim, litigation, proceeding or investigation pending or, to the knowledge of Borrower, threatened against or affecting Borrower or any of its Subsidiaries, their respective properties or business or this Agreement or any of the other Loan Documents or any of the transactions contemplated hereby or thereby before or by any court, tribunal, arbitrator or other Governmental Authority involving an aggregate amount in dispute in excess of Two Million Dollars ($2,000,000.00).

5.5 Title to and Condition of Assets . Borrower and each of its Subsidiaries has good, valid and marketable title to all of its properties and assets (whether real or personal) free and clear of all Encumbrances other than Permitted Liens. All personal property of Borrower or any of its Subsidiaries which is necessary for Borrower’s or its Subsidiary’s operations is in good operating condition and repair, normal wear and tear excepted, and is suitable and adequate for the uses for which it is being used.

5.6 Loan Application . The statements (other than projections) made and the documents delivered by Borrower or any of its Subsidiaries to the Lender (including, without limitation, any financial statements) in connection with its application for the Revolving Loan, when taken as a whole, are true, correct and complete in all material respects, omit no material facts, are not misleading, and present fairly the condition (financial or otherwise) of Borrower and its Subsidiaries. The projections contained in the materials referenced above are based upon reasonable estimates and assumptions, all of which are reasonable in light of the conditions which existed at the time the projections were made, and reflect the good faith estimate of the Borrower of the results of operations and other information projected therein, provided that no representation is made that the assumptions will prove to be correct.

5.7 No Change . No Material Adverse Change has occurred since June 30, 2007.

5.8 Taxes . Borrower and each of its Subsidiaries has timely filed all tax returns and other material reports required by any Governmental Authority to be filed by Borrower and its Subsidiaries, and such returns and reports are, after due inquiry, reasonably believed to be true and correct at the time of filing thereof. Borrower and each of its Subsidiaries has paid all taxes, assessments and other government charges imposed upon it or its income, profits or properties, or upon any part thereof, other than those presently payable without penalty or interest (or as are being contested in good faith by appropriate proceedings and with respect to which adequate reserves are being maintained), and Borrower and each of its Subsidiaries has timely filed all claims for refunds to which it is entitled. The amounts reserved as a liability for income and other taxes payable in the most recent financial statements of Borrower and its Subsidiaries provided to the Lender are sufficient for the payment of all unpaid federal, state, county and local income, excise, property and other taxes, whether or not disputed, of Borrower and its Subsidiaries accrued for or applicable to the period and on the dates of such financial statements and all years and periods prior thereto, and for which Borrower or any of its Subsidiaries may be liable in its own right or as a transferee of the assets of, or as successor to, any other Person.

5.9 No Event of Default . As of the date on which this representation and warranty is made (or remade), no Event of Default, and no event which with notice, lapse of time or both would constitute an Event of Default, has occurred and is continuing.

5.10 Compliance with Laws, Governance Documents and Agreements . Without limiting the provisions of Section 5.3 , Borrower and each of its Subsidiaries has complied and is in full compliance with (a) each agreement binding upon or affecting Borrower, its Subsidiaries or any of their respective properties except to the extent the failure to comply with such agreements would not have a Material Adverse Effect, (b) all applicable laws, ordinances, rules, regulations, judgments, orders, writs, injunctions, decrees, rules,

awards and other requirements of each Governmental Authority, court, tribunal, commission, board, bureau, arbitration panel or arbitrator except to the extent the
