The parties agree as follows:

1 ACCOUNTING AND OTHER TERMS

Accounting terms not defined in this Agreement shall be construed following GAAP. Calculations and determinations must be made following GAAP. Notwithstanding the foregoing, all financial calculations (whether for pricing, covenants, or otherwise) shall be made with regard to Borrower only and not on a consolidated basis. The term “financial statements” includes the notes and schedules. The terms “including” and “includes” always mean “including (or includes) without limitation,” in this or any Loan Document. Capitalized terms not otherwise defined in this Agreement shall have the meanings set forth in Section 13. All other terms contained in this Agreement, unless otherwise indicated, shall have the meanings provided by the Code, to the extent such terms are defined therein.

2 LOAN AND TERMS OF PAYMENT

2.1 Promise to Pay. Borrower hereby unconditionally promises to pay Bank the unpaid principal amount of all Advances hereunder with all interest, fees and finance charges due thereon as and when due in accordance with this Agreement.

2.1.1 Financing of Accounts.

(a) Availability.

(i) Subject to the terms of this Agreement, Borrower may request that Bank finance specific Eligible Accounts. Bank may, in its good faith business discretion, finance such Eligible Accounts by extending credit to Borrower in an amount equal to the result of the Advance Rate multiplied by the face amount of the Eligible Account. Bank may, in its sole discretion, change the percentage of the Advance Rate for a particular Eligible Account on a case by case basis.

(ii) Subject to the terms of this Agreement after the occurrence of the Sale Event, and provided that Borrower is Streamline Facility Eligible, Borrower may request that Bank finance Eligible Accounts on an aggregate basis (the “Aggregate Eligible Accounts”). Bank may,

in its good faith business discretion, finance Aggregate Eligible Accounts by extending credit to Borrower in an amount equal to the result of the Advance Rate multiplied by the face amount of the Aggregate Eligible Accounts. Bank may, in its sole discretion, change the percentage of the Advance Rate for the Aggregate Eligible Accounts on a case by case basis.

(iii) Any extension of credit made pursuant to the terms of subsections (i) or (ii) above shall hereinafter be referred to as an “Advance”. When Bank makes an Advance, the Eligible Account or the Aggregate Eligible Accounts each become a separate “Financed Receivable”.

(b) Maximum Advances. The aggregate face amount of all Financed Receivables outstanding at any time may not exceed the Facility Amount. In addition and notwithstanding the foregoing, (i) prior to the occurrence of the Sale Event, the aggregate amount of Advances outstanding hereunder together with all Advances (as defined in the Exim Agreement) outstanding under the Exim Agreement may not exceed Five Million Dollars ($5,000,000.00) at any time, and (ii) the aggregate amount of Advances outstanding hereunder at any time may not exceed Three Million Dollars ($3,000,000.00).

(c) Borrowing Procedure. Borrower will deliver an Advance Request and Invoice Transmittal in the form attached hereto as Exhibit C signed by a Responsible Officer for each Advance it requests, accompanied by an accounts receivable aging, with respect to Advances based upon Aggregate Eligible Accounts, or by invoices (and any other documentation related thereto as requested by Bank), with respect to Advances based upon Eligible Accounts. Bank may rely on information set forth in or provided with the Advance Request and Invoice Transmittal.

(d) Credit Quality; Confirmations. Bank may, at its option, conduct a credit check of the Account Debtor for each Account requested by Borrower for financing hereunder in order to approve any such Account Debtor’s credit before agreeing to finance such Account. Bank may also verify directly with the respective Account Debtors the validity, amount and other matters relating to the Accounts (including confirmations of Borrower’s representations in Section 5.3) by means of mail, telephone or otherwise, either in the name of Borrower or Bank from time to time in its sole discretion.

(e) Accounts Notification/Collection. Bank may notify any Person owing Borrower money of Bank’s security interest in the funds and verify and/or collect the amount of the Account; provided, however, while Borrower is Streamline Facility Eligible, Bank will provide notice to Borrower of any such verification and/or collection.

(f) Early Termination. This Agreement may be terminated prior to the Maturity Date as follows: (i) by Borrower, effective three Business Days after written notice of termination is given to Bank; or (ii) by Bank at any time after the occurrence of an Event of Default, without notice, effective immediately. If this Agreement is terminated (A) by Bank in accordance with clause (ii) in the foregoing sentence, or (B) by Borrower for any reason, and at the time of such termination the Exim Agreement has been terminated or matured, Borrower shall pay to Bank a termination fee in an amount equal to Eighty Thousand Dollars ($80,000.00) (the “Early Termination Fee”). The Early Termination Fee shall be due and payable on the effective date of such termination and thereafter shall bear interest at a rate equal to the highest rate applicable to any of the Obligations. Notwithstanding the foregoing, Bank agrees to waive the Early Termination Fee if Bank agrees to refinance and redocument this Agreement under another division of Bank (in its sole and exclusive discretion) prior to the Maturity Date.

(g) Maturity. This Agreement shall terminate and all Obligations outstanding hereunder shall be immediately due and payable on the Maturity Date.

(h) Suspension of Advances. Borrower’s ability to request that Bank finance Eligible Accounts and Aggregate Eligible Accounts hereunder will terminate if, in Bank’s sole discretion, there has been a material adverse change in the general affairs, management, results of operation, condition (financial or otherwise) or the prospect of repayment of the Obligations, or there has been any material adverse deviation by Borrower from the most recent business plan of Borrower presented to and accepted by Bank prior to the execution of this Agreement.

(i) End of Streamline Facility Eligible Status. On any day that Borrower ceases to be Streamline Facility Eligible, all outstanding Advances made based on Aggregate Eligible Accounts shall be immediately due and payable, together with all Finance Charges accrued thereon. Provided no Event of Default then exists hereunder and subject to the terms of this Agreement, Bank may, in its good faith business discretion, agree to refinance the outstanding principal amount of such Advances with new Advances made based on specific Eligible Accounts (in accordance with this Agreement, including, without limitation, Section 2.1.1 hereof). In connection with same, Borrower shall deliver to Bank an Advance Request and Invoice Transmittal in the form attached hereto as Exhibit C containing detailed invoice reporting, signed by a Responsible Officer together with a current accounts receivable aging and a copy of each invoice, all in accordance with Section 6.2(g) hereof and Bank, in its good faith business discretion, may finance same (in accordance with this Agreement, including, without limitation, Section 2.1.1 hereof) and each Eligible Account financed shall thereafter be deemed to be a Financed Receivable for purposes of this Agreement. If, following such determination, the outstanding principal amount of the Obligations exceeds the amount of Advances Bank has agreed to make based on specific Eligible Accounts, Borrower shall immediately pay to Bank the excess and, in connection with same, hereby irrevocably authorizes Bank to debit any account of Borrower maintained by Borrower with Bank or any of Bank’s Affiliates for the amount of such excess.

(j) Commencement of Streamline Facility Eligible Status. On any day that Borrower becomes Streamline Facility Eligible, Borrower may request that Bank refinance the principal amount of all outstanding Advances made based upon Eligible Accounts as Advances made based upon Aggregate Eligible Accounts. In connection with such request, Borrower shall deliver to Bank an Advance Request and Invoice Transmittal in the form attached hereto as Exhibit C containing a current accounts receivable aging and Bank may, in its good faith business discretion, agree to finance same (in accordance with this Agreement, including, without limitation, Section 2.1.1 hereof) and the Aggregate Eligible Accounts financed shall thereafter be deemed to be a Financed Receivable for purposes of this Agreement. At the time of such refinancing, all accrued Financed Charges and Collateral Handling Fees accrued on the refinanced Advances shall be immediately due and payable. If, following such determination, the outstanding principal amount of the Obligations exceeds the amount of Advances Bank has agreed to make based on Aggregate Eligible Accounts, Borrower shall immediately pay to Bank the excess and, in connection with same, hereby irrevocably authorizes Bank to debit any account of Borrower maintained by Borrower with Bank for the amount of such excess.

2.1.2 Term Loan. The existing term loan made pursuant to the Prior Agreement shall be repaid as set forth herein.

(a) Outstanding Amount. Borrower hereby acknowledges that it currently has Six Hundred Eighty Thousand Five Hundred Fifty Five and 62/100 Dollars ($680,555.62) outstanding (the “Term Loan”) pursuant to the Prior Agreement, which will not be paid off at the time of the closing of this Agreement. As of the Effective Date, no further advances or extensions of credit with respect to the Term Loan may be requested or made, even if all or a portion of the Term Loan is prepaid.

(b) Interest.

(i) Interest Rate. The principal amount outstanding under the Term Loan shall accrue interest at a floating per annum rate equal to the Prime Rate plus one and three-quarters of one percent (1.75%).

(ii) Default Rate. Immediately upon the occurrence and during the continuance of an Event of Default, Obligations with respect to the Term Loan shall bear interest at a per annum rate which is five percentage points (5.0%) above the rate that is otherwise applicable thereto. Payment or acceptance of the increased interest rate provided in this Section 2.1.2(b) is not a permitted alternative to timely payment and shall not constitute a waiver of any Event of Default or otherwise prejudice or limit any rights or remedies of Bank.

(iii) 360-Day Year. Interest in respect of the Term Loan shall be computed on the basis of a 360-day year for the actual number of days elapsed.

(iv) Adjustment to Interest Rate. Changes to the interest rate based on changes to the Prime Rate shall be effective on the effective date of any change to the Prime Rate and to the extent of any such change.

(c) Repayment. Commencing on December 1, 2009, and continuing on the first calendar day of each month thereafter, Borrower shall repay the Term Loan in (i) seven (7) monthly installments of principal in an amount equal to (A) Ninety Seven Thousand Two Hundred Twenty Two and 22/100 Dollars ($97,222.22) for each of the first six (6) payments, and (B) Ninety Seven Thousand Two Hundred Twenty Two and 30/100 Dollars ($97,222.30) for the seventh (7th) payment, plus (ii) monthly payments of accrued interest. Borrower’s final payment, due on June 1, 2010, shall include all outstanding principal and accrued and unpaid interest under the Term Loan.

(d) Cash Security. As of the Effective Date and thereafter until the Sale Event occurs, Borrower shall provide and maintain at Bank at all times a first priority security interest in cash in a segregated account in an amount equal to the full amount of the outstanding Obligations with respect to the Term Loan.

2.2 Collections, Finance Charges, Remittances and Fees. The Obligations shall be subject to the following fees and Finance Charges. Unpaid fees and Finance Charges may, in Bank’s discretion, accrue interest and fees as described in Section 9.2 hereof.

2.2.1 Collections. Collections will be credited to the Financed Receivable Balance for such Financed Receivable, but if there is an Event of Default, Bank may apply Collections to the Obligations in any order it chooses. If Bank receives a payment for both a Financed Receivable and a non-Financed Receivable, the funds will first be applied to the Financed Receivable and, if there is no Event of Default then existing, the excess will be remitted to Borrower, subject to Section 2.2.7.

2.2.2 Facility Fee. A fully earned, non-refundable facility fee of Twenty Thousand Dollars ($20,000.00) is due upon execution of this Agreement (the “Facility Fee”).

2.2.3 Finance Charges. In computing Finance Charges on the Obligations under this Agreement, all Collections received by Bank shall be deemed applied by Bank on account of the Obligations three (3) Business Days after receipt of the Collections. Borrower will pay a finance charge (the “Finance Charge”) on the Financed Receivable Balance which is equal to the Applicable Rate divided by 360 multiplied by the number of days each such Financed Receivable is outstanding multiplied by (a) with respect to Financed Receivables based on Eligible Accounts, the outstanding Financed Receivable Balance, and (b) with respect to Financed Receivables based on Aggregate Eligible Accounts, the outstanding Streamline Account Balance. Except as otherwise provided in Section 2.1.1(i), Section 2.1.1(j) and Section 2.3.1(b)(i), the Finance Charge is payable when the Advance made based on such Financed Receivable is payable in accordance with Section 2.3 hereof. After an Event of Default, the Applicable Rate will increase an additional five percent (5.0%) per annum effective immediately upon the occurrence of such Event of Default. In the event that the aggregate amount of Finance Charges earned by Bank in any Reconciliation Period during which Borrower is not Streamline Facility Eligible under this Agreement and the Exim Agreement is less than the Minimum Finance Charge, Borrower shall pay to Bank an additional Finance Charge equal to (i) the Minimum Finance Charge minus (ii) the aggregate amount of all Finance Charges earned by Bank under this Agreement and the Exim Agreement in such Reconciliation Period. Such additional Finance Charge shall be payable on the first day of the next Reconciliation Period.

2.2.4 Collateral Handling Fee. With respect to Financed Receivables based upon Eligible Accounts, Borrower will pay to Bank a collateral handling fee equal to 0.30% per month of the Financed Receivable Balance for each such Financed Receivable outstanding based upon a 360 day year (the “Collateral Handling Fee”). This fee is charged on a daily basis which is equal to the Collateral Handling Fee divided by 30, multiplied by the number of days each such Financed Receivable is outstanding, multiplied by the outstanding Financed Receivable Balance. Except as otherwise provided in Section 2.1.1(j), the Collateral Handling Fee is payable when the Advance made based on such Financed Receivable is payable in accordance with Section 2.3 hereof. In computing Collateral Handling Fees under this Agreement, all Collections received by Bank shall be deemed applied by Bank on account of Obligations three (3) Business Days after receipt of the Collections. After an Event of Default, the Collateral Handling Fee will increase an additional 0.50% effective immediately upon such Event of Default.

2.2.5 Accounting. After each Reconciliation Period, Bank will provide an accounting of the transactions for that Reconciliation Period, including the amount of all Financed Receivables, all Collections, Adjustments, Finance Charges, Collateral Handling Fees and the Facility Fee. If Borrower does not object to the

accounting in writing within thirty (30) days it shall be considered accurate. All Finance Charges and other interest and fees are calculated on the basis of a 360 day year and actual days elapsed.

2.2.6 Deductions. Bank may deduct fees, Finance Charges, Advances which become due pursuant to Section 2.3, and other amounts due pursuant to this Agreement from any Advances made or Collections received by Bank.

2.2.7 Lockbox; Account Collection Services.

(a) Borrower shall direct each Account Debtor (and each depository institution where proceeds of Accounts are on deposit) to remit payments with respect to the Accounts to a lockbox account established with Bank or to wire transfer payments to a cash collateral account that Bank controls (collectively, the “Lockbox”). It will be considered an immediate Event of Default if the Lockbox is not set-up and operational on the Effective Date.

(b) For any time at which such Lockbox is not established, the proceeds of the Accounts shall be paid by the Account Debtors to an address consented to by Bank. Upon receipt by Borrower of such proceeds, Borrower shall immediately transfer and deliver same to Bank, along with a detailed cash receipts journal. Provided no Event of Default exists or an event that with notice or lapse of time will be an Event of Default, within three (3) days of receipt of such amounts by Bank, Bank will turn over to Borrower the proceeds of the Accounts other than Collections with respect to Financed Receivables and the amount of Collections in excess of the amounts for which Bank has made an Advance to Borrower, less any amounts due to Bank, such as the Finance Charge, the Facility Fee, payments due to Bank, other fees and expenses, or otherwise; provided, however, Bank may hold such excess amount with respect to Financed Receivables as a reserve until the end of the applicable Reconciliation Period if Bank, in its discretion, determines that other Financed Receivable(s) may no longer qualify as an Eligible Account or an Aggregate Eligible Account at any time prior to the end of the subject Reconciliation Period. This Section 2.2.7 does not impose any affirmative duty on Bank to perform any act other than as specifically set forth herein. All Accounts and the proceeds thereof are Collateral and if an Event of Default occurs, Bank may apply the proceeds of such Accounts to the Obligations.

2.2.8 Bank Expenses. Borrower shall pay all Bank Expenses (including reasonable attorneys’ fees and expenses, plus expenses, for documentation and negotiation of this Agreement) incurred through and after the Effective Date, when due.

2.3 Repayment of Obligations; Adjustments.

2.3.1 Repayment.

(a) With respect to Advances made based on specific Eligible Accounts, Borrower will repay each Advance on the earliest of: (i) the date on which payment is received of the Financed Receivable with respect to which the Advance was made, (ii) the date on which the Financed Receivable is no longer an Eligible Account, (iii) the date on which any Adjustment is asserted to the Financed Receivable (but only to the extent of the Adjustment if the Financed Receivable remains otherwise an Eligible Account), (iv) the date on which there is a breach of any warranty or representation set forth in Section 5.3, or a breach of any covenant in this Agreement, (v) the Maturity Date (including any early termination), or (vi) as required pursuant to Section 2.1.1(j). Each payment will also include all accrued Finance Charges and Collateral Handling Fees with respect to such Advance and all other amounts then due and payable hereunder.

(b) With respect to Advances made based on Aggregate Eligible Accounts:

(i) Borrower will pay to Bank, on the first day of each Reconciliation Period, all accrued Finance Charges on the Advances made based on the Aggregate Eligible Accounts;

(ii) Borrower will pay the principal amount of each Advance made based on Aggregate Eligible Accounts on the earliest of: (A) the date the Financed Receivable (or any portion thereof) is no longer an Eligible Account, or an Adjustment has been made to any portion of the Aggregate Eligible Accounts, or any Account comprising the Aggregate Eligible Accounts has been paid by the Account Debtor (but in each case only up to the portion of Advances such

that the aggregate Financed Receivable Balance (net of any Accounts that are paid, not Eligible Accounts, or subject to an Adjustment) is not less than 125% of the aggregate Advances made thereon), (B) the date on which there is a breach of any warranty or representation set forth in Section 5.3 or a breach of any covenant in this Agreement, (C) the Maturity Date (including any early termination), or (D) as required pursuant to Section 2.1.1(i). Each payment shall also include all accrued Finance Charges with respect to such Advance and all other amounts then due and payable hereunder; and

(iii) In addition to the foregoing, Borrower hereby authorizes Bank to, up to one (1) time per Reconciliation Period, refinance all outstanding Advances which are made based upon Aggregate Eligible Accounts. Each such refinancing shall consist of the creation of a new “placeholder note” on the books of Bank which evidences the Financed Receivable Balance with respect to all Advances which are outstanding which are based upon Aggregate Eligible Accounts.

2.3.2 Repayment on Event of Default. When there is an Event of Default, Borrower will, if Bank demands (or, upon the occurrence of an Event of Default under Section 8.5, immediately without notice or demand from Bank) repay all of the Advances. The demand may, at Bank’s option, include the Advance for each Financed Receivable then outstanding and all accrued Finance Charges, Collateral Handling Fees, attorneys’ and professional fees, court costs and expenses, and any other Obligations.

2.3.3 Debit of Accounts. Bank may debit any of Borrower’s deposit accounts for payments or any amounts Borrower owes Bank hereunder. Bank shall promptly notify Borrower when it debits Borrower’s accounts. These debits shall not constitute a set-off.

2.3.4 Adjustments. If, at any time during the term of this Agreement, any Account Debtor asserts an Adjustment, Borrower issues a credit memorandum, or any of the representations and warranties in Section 5.3 or covenants in this Agreement are no longer true in all material respects, Borrower will promptly advise Bank.

2.4 Power of Attorney. Borrower irrevocably appoints Bank and its successors and assigns as attorney-in-fact and authorizes Bank, to: (a) following the occurrence of an Event of Default, (i) sell, assign, transfer, pledge, compromise, or discharge all or any part of the Financed Receivables; (ii) demand, collect, xxx, and give releases to any Account Debtor for monies due and compromise, prosecute, or defend any action, claim, case or proceeding about the Financed Receivables, including filing a claim or voting a claim in any bankruptcy case in Bank’s or Borrower’s name, as Bank chooses; and (iii) prepare, file and sign Borrower’s name on any notice, claim, assignment, demand, draft, or notice of or satisfaction of lien or mechanics’ lien or similar document; and (b) regardless of whether there has been an Event of Default, (i) notify all Account Debtors to pay Bank directly; (ii) receive, open, and dispose of mail addressed to Borrower; (iii) endorse Borrower’s name on checks or other instruments (to the extent necessary to pay amounts owed pursuant to this Agreement); and (iv) execute on Borrower’s behalf any instruments, documents, financing statements to perfect Bank’s interests in the Financed Receivables and Collateral and do all acts and things necessary or expedient, as determined solely and exclusively by Bank, to protect or preserve, Bank’s rights and remedies under this Agreement, as directed by Bank.

Any such financing statements may indicate the Collateral as “all assets of the Debtor” or words of similar effect, or as being of an equal or lesser scope, or with greater detail, all in Bank’s discretion.

5 REPRESENTATIONS AND WARRANTIES

Borrower represents and warrants as follows:

5.1 Due Organization and Authorization. Borrower and each of its Subsidiaries are duly existing and in good standing as Registered Organizations in their respective jurisdictions of formation and are qualified and licensed to do business and are in good standing in any jurisdiction in which the conduct of their respective business or ownership of property requires that they be qualified except where the failure to do so could not reasonably be expected to have a material adverse effect on Borrower’s business. Borrower has previously delivered to Bank the Perfection Certificate. Borrower represents and warrants to Bank that (a) Borrower’s exact legal name is that indicated on the Perfection Certificate and on the signature page hereof; (b) Borrower is an organization of the type and is organized in the jurisdiction set forth in the Perfection Certificate; (c) the Perfection Certificate accurately sets forth Borrower’s organizational identification number or accurately states that Borrower has none; (d) the Perfection Certificate accurately sets forth Borrower’s place of business, or, if more than one, its chief executive office as well as Borrower’s mailing address (if different than its chief executive office); (e) Borrower (and each of its predecessors) has not, in the past five (5) years, changed its jurisdiction of formation, organizational structure or type, or any organizational number assigned by its jurisdiction; and (f) all other information set forth on the Perfection Certificate pertaining to Borrower and each of its Subsidiaries is accurate and complete (it being understood and agreed that Borrower may from time to time update certain information in the Perfection Certificate after the Effective Date to the extent permitted by one or more specific provisions in this Agreement). If Borrower is not now a Registered Organization but later becomes one, Borrower shall promptly notify Bank of such occurrence and provide Bank with Borrower’s organizational identification number.

The execution, delivery and performance by Borrower of the Loan Documents to which it is a party have been duly authorized, and do not (i) conflict with any of Borrower’s organizational documents, (ii) contravene, conflict with, constitute a default under or violate any material Requirement of Law, (iii) contravene, conflict or violate any applicable order, writ, judgment, injunction, decree, determination or award of any Governmental Authority by which Borrower or any of its Subsidiaries or any of their property or assets may be bound or affected, (iv) require any action by, filing, registration, or qualification with, or Governmental Approval from, any Governmental Authority (except such Governmental Approvals which have already been obtained and are in full force and effect), or (v) constitute an event of default under any material agreement by which Borrower is bound.

5.2 Collateral. Borrower has good title, has rights in, and the power to transfer each item of the Collateral upon which it purports to xxxxx x Xxxx hereunder, free and clear of any and all Liens except Permitted Liens. Borrower has no deposit accounts other than the deposit accounts with Bank, the deposit accounts, if any, described in the Perfection Certificate delivered to Bank in connection herewith, or of which Borrower has given Bank notice and taken such actions as are necessary to give Bank a perfected security interest therein. The Accounts are bona fide, existing obligations of the Account Debtors.

All Inventory is in all material respects of good and marketable quality, free from material defects.

The Collateral is not in the possession of any third party bailee (such as a warehouse) except as otherwise provided in the Perfection Certificate. None of the components of the Collateral shall be maintained at locations other than as provided in the Perfection Certificate or as permitted pursuant to Section 7.2. In the event that Borrower, after the date hereof, intends to store or otherwise deliver any portion of the Collateral to a bailee, then Borrower will first receive the written consent of Bank and such bailee must execute and deliver a bailee agreement in form and substance satisfactory to Bank in its sole discretion.

Except as noted on the Perfection Certificate, Borrower is not a party to, nor is bound by, any material license or other agreement with respect to which Borrower is the licensee (a) that prohibits or otherwise restricts Borrower from granting a security interest in Borrower’s interest in such license or agreement or any other property, or (b) for which a default under or termination of could interfere with Bank’s right to sell any Collateral. Without prior consent from Bank, Borrower shall not enter into, or become bound by, any such license or agreement which is reasonably likely to have a material impact on Borrower’s business or financial condition. Borrower shall take such steps as Bank requests to obtain the consent of, or waiver by, any person whose consent or waiver is necessary for

all such licenses or contract rights to be deemed “Collateral” and for Bank to have a security interest in it that might otherwise be restricted or prohibited by law or by the terms of any such license or agreement, whether now existing or entered into in the future.

(i) Bank has the right to endorse and/or require Borrower to endorse all payments received on Financed Receivables and all proceeds of Collateral; and

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

5.4 Litigation. Except as set forth on Schedule 5.4 attached hereto, there are no actions or proceedings pending or, to the knowledge of Borrower’s Responsible Officers, threatened in writing by or against Borrower or any Subsidiary in which an adverse decision could reasonably be expected to cause a Material Adverse Change.

5.5 No Material Deterioration in Financial Statements. All consolidated financial statements for Borrower and any Subsidiaries 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.

5.6 Solvency. The fair salable value of Borrower’s assets (including goodwill minus disposition costs) exceeds the fair value of its liabilities; 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.

5.7 Regulatory Compliance. Borrower is not an “investment company” or a company “controlled” by an “investment company” under the Investment Company Act of 1940, as amended. Borrower is not engaged as one of its important activities in extending credit for margin stock (under Regulations X, T and U of the Federal Reserve Board of Governors). Neither Borrower nor any of its Subsidiaries is a “holding company” or an “affiliate” of a “holding company” or a “subsidiary company” of a “holding company” as each term is defined and used in the

Public Utility Holding Company Act of 2005. 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. None of Borrower’s or any Subsidiary’s properties or assets has been used by Borrower or any Subsidiary or, to the best of Borrower’s knowledge, by previous Persons, in disposing, producing, storing, treating, or transporting any hazardous substance other than legally. Borrower and each of its Subsidiaries have 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 their respective businesses as currently conducted.

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

5.9 Tax Returns and Payments; Pension Contributions. Borrower and each Subsidiary have timely filed all required tax returns and reports, and Borrower and each Subsidiary have timely paid all foreign, federal, state and local taxes, assessments, deposits and contributions owed by Borrower and each Subsidiary. Borrower may defer payment of any contested taxes, provided that Borrower (a) in good faith contests its obligation to pay the taxes by appropriate proceedings promptly and diligently instituted and conducted, (b) notifies Bank in writing of the commencement of, and any material development in, the proceedings, and (c) posts bonds or takes any other steps required to prevent the governmental authority levying such contested taxes from obtaining a Lien upon any of the Collateral that is other than a “Permitted Lien”. Borrower is unaware of any claims or adjustments proposed for any of Borrower's prior tax years which could result in additional taxes becoming due and payable by Borrower. Borrower has paid all amounts necessary to fund all present pension, profit sharing and deferred compensation plans in accordance with their terms, and Borrower has not withdrawn from participation in, and has not permitted partial or complete termination of, or permitted the occurrence of any other event with respect to, any such plan which could reasonably be expected to result in any liability of Borrower, including any liability to the Pension Benefit Guaranty Corporation or its successors or any other governmental agency.

5.10 Full Disclosure. No written representation, warranty or other statement of Borrower in any certificate or written statement given to Bank, as of the date such representation, warranty, or other statement was made, taken together with all such written certificates and written statements given 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 (it being recognized by Bank that projections and forecasts provided by Borrower in good faith and based upon reasonable assumptions are not viewed as facts and that actual results during the period or periods covered by such projections and forecasts may differ from the projected or forecasted results).

After the occurrence of an Event of Default, Bank may audit Borrower’s Collateral, including, but not limited to, Borrower’s Accounts at Borrower’s expense and at Bank’s sole and exclusive discretion and without notification and authorization from Borrower.

Borrower shall make, and cause each Subsidiary to make, timely payment of all federal, state, and local taxes or assessments (other than taxes and assessments which Borrower is contesting in good faith, with adequate reserves maintained in accordance with GAAP) and will deliver to Bank, on demand, appropriate certificates attesting to such payments.

6.4 Insurance. Keep its business and the Collateral insured for risks and in amounts standard for companies in Borrower’s industry and location, and as Bank may reasonably request.

All property policies shall have a lender’s loss payable endorsement showing Bank as the sole lender loss payee and waive subrogation against Bank, and all liability policies shall show, or have endorsements showing, Bank as an additional insured. All policies (or the loss payable and additional insured endorsements) shall provide that the insurer must give Bank at least twenty (20) days notice before canceling, amending, or declining to renew its policy. At Bank’s request, Borrower shall deliver certified copies of policies and evidence of all premium payments. Proceeds payable under any policy shall, at Bank’s option, be payable to Bank on account of the Obligations. Notwithstanding the foregoing, (a) so long as no Event of Default has occurred and is continuing, Borrower shall have the option of applying the proceeds of any casualty policy up to Two Hundred Fifty Thousand Dollars ($250,000.00) with respect to any loss, but not exceeding Five Hundred Thousand Dollars ($500,000.00) in the aggregate for all losses under all casualty policies in any one year, toward the replacement or repair of destroyed or damaged property; provided that any such replaced or

repaired property (i) shall be of equal or like value as the replaced or repaired Collateral and (ii) shall be deemed Collateral in which Bank has been granted a first priority security interest, and (b) after the occurrence and during the continuance of an Event of Default, all proceeds payable under such casualty policy shall, at the option of Bank, be payable to Bank on account of the Obligations. If Borrower fails to obtain insurance as required under this Section 6.4 or to pay any amount or furnish any required proof of payment to third persons and Bank, Bank may make all or part of such payment or obtain such insurance policies required in this Section 6.4, and take any action under the policies Bank deems prudent.

In addition, for each such account that Borrower or Guarantor at any time opens or maintains, Borrower shall, at Bank’s request and option, pursuant to an agreement in form and substance acceptable to Bank, cause the depository bank or securities intermediary to agree that such account is the collateral of Bank pursuant to the terms hereunder, which control agreement may not be terminated without the prior written consent of Bank. The provisions of the previous sentence shall not apply to deposit accounts exclusively used for payroll, payroll taxes and other employee wage and benefit payments to or for the benefit of Borrower’s employees.

(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) demand that Borrower (i) deposits cash with Bank in an amount equal to the aggregate amount of any letters of credit remaining undrawn, as collateral security for the repayment of any future drawings under such letters of credit, and Borrower shall forthwith deposit and pay such amounts, and (ii) pay in advance all letter of credit fees scheduled to be paid or payable over the remaining term of any letters of credit;

(d) settle or adjust disputes and claims directly with Account Debtors for amounts, on terms and in any order that Bank considers advisable and notify any Person owing Borrower money of Bank’s security interest in such funds and verify the amount of such account. Borrower shall 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;

(e) make any payments and do any acts it considers necessary or reasonable to protect its security interest in the Collateral. Borrower shall assemble the Collateral if Bank requests 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;

(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. Bank is hereby granted a non-exclusive, royalty-free license or other right to use, without charge, Borrower’s labels, patents, copyrights, mask works, rights of use of any name, trade secrets, trade names, trademarks, service marks, and advertising matter, or any similar property as it pertains to the Collateral, in completing production of, advertising for sale, and selling any Collateral and, in connection with Bank’s exercise of

its rights under this Section 9.1, Borrower’s rights under all licenses and all franchise agreements inure to Bank’s benefit;

(h) place a “hold” on any account maintained with Bank and/or 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;

(i) demand and receive possession of Borrower’s Books; and

(j) exercise all rights and remedies available to Bank under the Loan Documents or at law or equity, including all remedies provided under the Code (including disposal of the Collateral pursuant to the terms thereof).

9.2 Protective Payments. If Borrower fails to obtain insurance called for by Section 6.4 or fails to pay any premium thereon or fails to pay any other amount which Borrower is obligated to pay under this Agreement or by any other Loan Document, Bank may obtain such insurance or make such payment, and all amounts so paid by Bank are Bank Expenses and immediately due and payable, bearing interest at the then highest applicable rate, and secured by the Collateral. Bank will make reasonable effort to provide Borrower with notice of Bank obtaining such insurance at the time it is obtained or within a reasonable time thereafter. No payments by Bank are deemed an agreement to make similar payments in the future or Bank’s waiver of any Event of Default.

9.3 Bank’s Liability for Collateral. So long as Bank complies with reasonable banking practices regarding the safekeeping of Collateral in possession or under the control of Bank, Bank shall not be liable or responsible 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. Borrower bears all risk of loss, damage or destruction of the Collateral.

9.4 Remedies Cumulative. Bank’s failure, at any time or times, to require strict performance by Borrower of any provision of this Agreement or any other Loan Document shall not waive, affect, or diminish any right of Bank thereafter to demand strict performance and compliance herewith or therewith. No waiver hereunder shall be effective unless signed by Bank and then is only effective for the specific instance and purpose for which it is given. Bank’s rights and remedies under this Agreement and the other Loan Documents 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 in exercising any remedy is not a waiver, election, or acquiescence.

9.5 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.

11 CHOICE OF LAW, VENUE AND JURY TRIAL WAIVER

Massachusetts law governs the Loan Documents without regard to principles of conflicts of law. Borrower and Bank each submit to the exclusive jurisdiction of the State and Federal courts in Massachusetts; provided, however, that if for any reason Bank cannot avail itself of such courts in the Commonwealth of Massachusetts,

Borrower accepts jurisdiction of the courts and venue in Santa Xxxxx County, California. Notwithstanding the foregoing, nothing in this Agreement shall be deemed to operate to preclude Bank from bringing suit or taking other legal action in any other jurisdiction to realize on the Collateral or any other security for the Obligations, or to enforce a judgment or other court order in favor of Bank. Borrower expressly submits and consents in advance to such jurisdiction in any action or suit commenced in any such court, and Borrower hereby waives any objection that it may have based upon lack of personal jurisdiction, improper venue, or forum non conveniens and hereby consents to the granting of such legal or equitable relief as is deemed appropriate by such court. Borrower hereby waives personal service of the summons, complaints, and other process issued in such action or suit and agrees that service of such summons, complaints, and other process may be made by registered or certified mail addressed to Borrower at the address set forth in the preamble of this Agreement and that service so made shall be deemed completed upon the earlier to occur of Borrower’s actual receipt thereof or three (3) days after deposit in the U.S. mails, proper postage prepaid.

BORROWER AND BANK EACH WAIVE THEIR RIGHT TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION ARISING OUT OF OR BASED UPON THIS AGREEMENT, THE LOAN DOCUMENTS OR ANY CONTEMPLATED TRANSACTION, INCLUDING CONTRACT, TORT, BREACH OF DUTY AND ALL OTHER CLAIMS. THIS WAIVER IS A MATERIAL INDUCEMENT FOR BOTH PARTIES TO ENTER INTO THIS AGREEMENT. EACH PARTY HAS REVIEWED THIS WAIVER WITH ITS COUNSEL.

12 GENERAL PROVISIONS

12.1 Successors and Assigns. This Agreement binds and is for the benefit of the successors and permitted assigns of each party. Borrower may not assign this Agreement or any rights or obligations under it without Bank’s prior written consent which may be granted or withheld in Bank’s discretion.

12.2 Indemnification. Borrower agrees to indemnify, defend, and hold Bank and its officers, directors, employees, agents, attorneys or any other Person affiliated with or representing Bank (each, an “Indemnified Person”) harmless against: (a) all obligations, demands, claims, and liabilities (collectively, “Claims”) asserted by any other party in connection with the transactions contemplated by the Loan Documents; and (b) all losses or Bank Expenses incurred, or paid by such Indemnified Person from, following, or arising from transactions between Bank and Borrower (including reasonable attorneys’ fees and expenses), except for Claims and/or losses directly caused by such Indemnified Person’s gross negligence or willful misconduct.

12.3 Right of Set-Off.
