5.1          Due Organization and Authorization.

Borrower and each Subsidiary is duly existing and in good standing in its state of formation and qualified and licensed to do business in, and in good standing in, any state in which the conduct of its business or its ownership of property requires that it be qualified, except where the failure to do so could not reasonably be expected to cause a Material Adverse Change. Borrower has not changed its state of formation or its organizational structure or type or any organizational number (if any) assigned by its jurisdiction of formation.

The execution, delivery and performance of the Loan Documents have been duly authorized, and do not conflict with Borrower’s formation documents, nor constitute an event of default under any material agreement by which Borrower is bound. Borrower is not in default under any agreement to which or by which it is bound in which the default could reasonably be expected to cause a Material Adverse Change.

5.2          Collateral.

Borrower has good title to the Collateral, free of Liens except Permitted Liens or Borrower has Rights to each asset that is Collateral. Borrower has no other deposit account, other than the deposit accounts described in the Schedule. The Accounts are bona fide, existing obligations, and the service or property has been performed or delivered to the account debtor or its agent for immediate shipment to and unconditional acceptance by the account debtor. The Collateral is not in the possession of any third party bailee (such as at a warehouse). In the event that Borrower, after the date hereof, intends to store or otherwise deliver the Collateral to such a bailee, then Borrower will receive the prior written consent of Bank and such bailee must acknowledge in writing that the bailee is holding such Collateral for the benefit of Bank. Borrower has no notice of any actual or imminent Insolvency Proceeding of any account debtor whose accounts are an Eligible Account in any Borrowing Base Certificate. All Inventory is in all material respects of good and marketable quality, free from material defects.

5.3          Litigation.

Except as shown in the Schedule, there are no actions or proceedings pending or, to the knowledge of Borrower’s Responsible Officers, threatened by or against Borrower or any Subsidiary in which a likely adverse decision could reasonably be expected to cause a Material Adverse Change.

5.4          No Material Adverse Change in Financial Statements.

All consolidated financial statements for Borrower, and any Subsidiary, delivered to Bank fairly present in all material respects Borrower’s consolidated financial condition and Borrower’s consolidated results of operations. There has not been any material deterioration in Borrower’s consolidated financial condition since the date of the most recent financial statements submitted to Bank.

4

5.5          Solvency.

The fair salable value of Borrower’s assets (including goodwill minus disposition costs) exceeds the fair value of its liabilities; the Borrower is not left with unreasonably small capital after the transactions in this Agreement; and Borrower is able to pay its debts (including trade debts) as they mature.

5.6          Regulatory Compliance.

Borrower is not an “investment company” or a company “controlled” by an “investment company” under the Investment Company Act.

Borrower has complied in all material respects with the Federal Fair Labor Standards Act. Borrower has not violated any laws, ordinances or rules, the violation of which could reasonably be expected to cause a Material Adverse Change.

Borrower and each Subsidiary has timely filed all required tax returns and paid, or made adequate provision to pay, all material taxes, except those being contested in good faith with adequate reserves under GAAP. Borrower and each Subsidiary has obtained all consents, approvals and authorizations of, made all declarations or filings with, and given all notices to, all government authorities that are necessary to continue its business as currently conducted, except where the failure to do so could not reasonably be expected to cause a Material Adverse Change.

5.7          Investments in Subsidiaries.

Borrower does not own any stock, partnership interest or other equity securities except for Permitted Investments.

5.8          Full Disclosure.

No written representation, warranty or other statement of Borrower in any certificate or written statement given to Bank (taken together with all such written certificates and written statements to Bank) contains any untrue statement of a material fact or omits to state a material fact necessary to make the statements contained in the certificates or statements not misleading.

When an Event of Default occurs and continues Bank may, without notice or demand, do any or all of the following:

(a)           Declare all Obligations immediately due and payable (but if an Event of Default described in Section 8.5 occurs all Obligations are immediately due and payable without any action by Bank);

(b)           Stop advancing money or extending credit for Borrower’s benefit under this Agreement or under any other agreement between Borrower and Bank;

(c)           Settle or adjust disputes and claims directly with account debtors for amounts, on terms and in any order that Bank considers advisable; notify any Person owing Borrower money of Bank’s security interest in the

9

funds and verify the amount of the Account. Borrower must collect all payments in trust for Bank and, if requested by Bank, immediately deliver the payments to Bank in the form received from the account debtor, with proper endorsements for deposit;

(d)           Make any payments and do any acts it considers necessary or reasonable to protect its security interest in the Collateral. Borrower will assemble the Collateral if Bank requires and make it available as Bank designates. Bank may enter premises where the Collateral is located, take and maintain possession of any part of the Collateral, and pay, purchase, contest, or compromise any Lien which appears to be prior or superior to its security interest and pay all expenses incurred. Borrower grants Bank a license to enter and occupy any of its premises, without charge, to exercise any of Bank’s rights or remedies;

(e)           Bank may place a “hold” on any account maintained with Bank and deliver a notice of exclusive control, any entitlement order, or other directions or instructions pursuant to any control agreement or similar agreements providing control of any Collateral;

(f)            Apply to the Obligations any (i) balances and deposits of Borrower it holds, or (ii) any amount held by Bank owing to or for the credit or the account of Borrower;

(g)           Ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, advertise for sale, and sell the Collateral; and

(h)           Dispose of the Collateral according to the Code.

9.2          Power of Attorney.

Effective only when an Event of Default occurs and continues, Borrower irrevocably appoints Bank as its lawful attorney to: (i) endorse Borrower’s name on any checks or other forms of payment or security; (ii) sign Borrower’s name on any invoice or bill of lading for any Account or drafts against account debtors, (iii) make, settle, and adjust all claims under Borrower’s insurance policies; (iv) settle and adjust disputes and claims about the Accounts directly with account debtors, for amounts and on terms Bank determines reasonable; and (v) transfer the Collateral into the name of Bank or a third party as the Code permits. Bank may exercise the power of attorney to sign Borrower’s name on any documents necessary to perfect or continue the perfection of any security interest regardless of whether an Event of Default has occurred. Bank’s appointment as Borrower’s attorney in fact, and all of Bank’s rights and powers, coupled with an interest, are irrevocable until all Obligations have been fully repaid and performed and Bank’s obligation to provide Credit Extensions terminates.

9.3          Bank Expenses.

If Borrower fails to pay any amount or furnish any required proof of payment to third persons, Bank may make all or part of the payment or obtain insurance policies required in Section 6.5, and take any action under the policies Bank deems prudent. Any amounts paid by Bank are Bank Expenses and immediately due and payable, bearing interest at the then applicable rate and secured by the Collateral. No payments by Bank are deemed an agreement to make similar payments in the future or Bank’s waiver of any Event of Default.

9.4          Bank’s Liability for Collateral.

If Bank complies with reasonable banking practices and Section 9-207 of the Code, it is not liable for: (a) the safekeeping of the Collateral; (b) any loss or damage to the Collateral; (c) any diminution in the value of the Collateral; or (d) any act or default of any carrier, warehouseman, bailee, or other person. Except as provided above, Borrower bears all risk of loss, damage or destruction of the Collateral.

10

9.5          Remedies Cumulative.

Bank’s rights and remedies under this Agreement, the Loan Documents, and all other agreements are cumulative. Bank has all rights and remedies provided under the Code, by law, or in equity. Bank’s exercise of one right or remedy is not an election, and Bank’s waiver of any Event of Default is not a continuing waiver. Bank’s delay is not a waiver, election, or acquiescence. No waiver is effective unless signed by Bank and then is only effective for the specific instance and purpose for which it was given.

9.6          Demand Waiver.

Borrower waives demand, notice of default or dishonor, notice of payment and nonpayment, notice of any default, nonpayment at maturity, release, compromise, settlement, extension, or renewal of accounts, documents, instruments, chattel paper, and guarantees held by Bank on which Borrower is liable.

10           NOTICES

All notices or demands by any party about this Agreement or any other related agreement must be in writing and be personally delivered or sent by an overnight delivery service, by certified mail, postage prepaid, return receipt requested, or by telefacsimile to the addresses set forth at the beginning of this Agreement. A party may change its notice address by giving the other party written notice.
