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. 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 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 and provided that Borrower is Streamline Facility Eligible, Borrower may request that Bank finance Eligible Accounts on an aggregate basis. Bank may, in its good faith business discretion, finance Eligible Accounts on an aggregate basis by extending credit to Borrower in an amount equal to the result of the Advance Rate multiplied by the aggregate face amount of a summary listing of Eligible Accounts provided to Bank (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 Credit Extension made pursuant to the terms of subsection (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, the aggregate amount of Advances outstanding at any time hereunder, together with the Aggregate Amount of Advances (as defined in the EXIM Agreement) outstanding at any time pursuant to the EXIM Agreement, may not exceed Fourteen Million Dollars ($14,000,000.00).

(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, if Borrower is then Streamline Facility Eligible, or by invoices, if Borrower is not Streamline Facility Eligible. 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, in consultation with Borrower (provided that such consultation will not be required upon the occurrence and during the continuance of an Event of Default), 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 (such verifications are to be done in consultation with Borrower, provided that such consultation will not be required upon the occurrence and during the continuance of an Event of Default) and/or collect the amount of the Account.

(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 and during the continuance of an Event of Default, without notice, effective immediately. If this Agreement is terminated for any reason prior to the Maturity Date, and at such time the Exim Agreement and the Term Loan Agreement have been terminated or have matured pursuant to their terms, Borrower shall pay to Bank a termination fee in an amount equal to One Hundred Fifty Thousand Dollars ($150,000.00) (the “Early Termination Fee”); provided that, in no event shall the Early Termination Fee and/or the Prepayment Fee (as defined in the Term Loan Agreement) paid by Borrower under this Agreement, the Exim Agreement and the Term Loan Agreement exceed, in the aggregate, One Hundred Fifty Thousand Dollars ($150,000.00). 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, 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 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(h) hereof and Bank may, in its good faith business discretion, 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.

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 in accordance with Section 2.2.7, but if there is an Event of Default, Bank may apply Collections to the Obligations in any order it chooses.

2.2.2                     Loan Fees.

(a)                                  A fully earned, non-refundable facility fee of One Hundred Seventy-Five Thousand Dollars ($175,000.00) is due upon execution of this Agreement (the “Facility Fee”).

(b)                                 A fully earned, non-refundable anniversary fee of One Hundred Seventy-Five Thousand Dollars ($175,000.00) (the “Anniversary Fee”) shall be earned as of the date hereof, and shall be due and payable on the date that is one year from the Closing Date.

The Facility Fee and the Anniversary Fee are hereinafter collectively referred to as the “Loan Fees”.

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 each Financed Receivable which is equal to the Applicable Rate divided by 360 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 2.3.1(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 has occurred and is continuing, 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 and Collateral Handling Fees earned by Bank under this Agreement and the Exim Agreement in any fiscal quarter 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 and Collateral Handling Fees earned by Bank in such fiscal quarter. Such additional Finance Charge shall be payable on the first day of the next fiscal quarter.

2.2.4.                  Collateral Handling Fee. Borrower will pay to Bank a Collateral handling fee equal to 0.50% per month of the Financed Receivable Balance for each Financed Receivable outstanding based

upon a 360 day year (the “Collateral Handling Fee”); provided, however, for any Subject Month (as of the first calendar day of such month), to the extent that Borrower maintained Liquidity of at least Two Million Five Hundred Thousand Dollars ($2,500,000.00) at all times during the applicable Testing Month, the Collateral Handling Fee shall be equal to 0.35% per month of the Financed Receivable Balance for each Financed Receivable outstanding based upon a 360 day year; provided further, however, for any Subject Month (as of the first calendar day of such month), to the extent that Borrower maintained Liquidity of greater than Four Million Dollars ($4,000,000.00) at all times during the applicable Testing Month, the Collateral Handling Fee shall be equal to 0.10% per month of the Financed Receivable Balance for each Financed Receivable outstanding based upon a 360 day year. 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 2.3.1 (b)(i), 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 has occurred and is continuing, 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 Fee and the Loan Fees. 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)                                  As and when directed by Bank from time to time, at Bank’s option and at the sole and exclusive discretion of Bank (regardless of whether an Event of Default has occurred), 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 within thirty (30) days of the Closing 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, (i) if Borrower is not then Streamline Facility Eligible, 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 Loan Fees, payments due to Bank, other fees and expenses, or otherwise (other than with respect to any Financed Receivable that is not currently due), and (ii) if Borrower is then Streamline Facility Eligible, within three (3) days of receipt of such amounts by Bank, Bank will turn over to Borrower the proceeds of the Accounts other than amounts which are necessary to pay to Bank any principal amount due pursuant to Section 2.3.1(b)(ii); 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 at any time prior to the end of the subject Reconciliation Period. This Section 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                     Good Faith Deposit. Borrower has paid to Bank a deposit of Twenty-Five Thousand Dollars ($25,000.00) (the “Good Faith Deposit”) to initiate Bank’s due diligence review process. Any portion of the Good Faith Deposit not utilized to pay Bank Expenses shall be applied to the Facility Fee.

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 (v) the Maturity Date (including any early termination). 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 shall pay to Bank, on the first day of each Reconciliation Period, all accrued Finance Charges and Collateral Handling Fees on the Advances made based on the Aggregate Eligible Accounts;

(ii)           Borrower shall also 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; (C) the Maturity Date (including any early termination); or (D) as required pursuant to Section 2.1.1(i); 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 an Event of Default has occurred and is continuing, 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, the Early Termination Fee, 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 or if Borrower issues a credit memorandum or if any of the representations, warranties or covenants set forth in Section 5.3 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, sue, 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.

Collateral (subject only to Permitted Liens that are permitted to have superior priority to Bank’s security interest).

If the Agreement is terminated, Bank’s lien and security interest in the Collateral granted herein shall continue until Borrower fully satisfies its Obligations (other than inchoate indemnity obligations). Upon payment in full in cash of the Obligations (other than inchoate indemnity obligations) and at such time as this Agreement, the Term Loan Agreement and the Exim Agreement have been terminated, Bank’s Liens in the Collateral shall automatically terminate and all rights therein shall revert to Borrower and Bank shall, at Borrower’s sole cost and expense, deliver such documents and make such filings as Borrower may reasonably request to evidence such termination.

Notwithstanding the foregoing, it is expressly acknowledged and agreed that the security interest created in this Agreement only with respect to Export-Related Accounts Receivable, Export-Related Inventory and Export-Related General Intangibles (as such terms are defined in the Exim Agreement) is subject to and subordinate to the security interest granted to Bank in the Exim Agreement with respect to such Export-Related Accounts Receivable, Export-Related Inventory and Export-Related General Intangibles.

4.2                               Authorization to File Financing Statements. Borrower hereby authorizes Bank to file financing statements, without notice to Borrower, with all appropriate jurisdictions in order to perfect or protect Bank’s interest or rights hereunder, which 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, and may include a notice that any disposition of the Collateral, by Borrower or any other Person, shall be deemed to violate the rights of Bank under the Code.

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. In connection with this Agreement, Borrower has delivered to Bank a completed certificate signed by Borrower (the “Perfection Certificate”). Borrower represents and warrants to Bank that, except as may have been updated by a notification to Bank pursuant to Section 7.2: (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, except as indicated on the Perfection Certificate; and (f) all other information set forth on the Perfection Certificate pertaining to Borrower and each of its Subsidiaries is accurate and complete in all material respects. 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 its Subsidiaries or any of their property or assets may be bound, (iv) require any action by, filing, registration, or qualification with, or approval from any Governmental Authority (except such 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. Borrower is not in default under any agreement to which it is a party or by which it is bound in which the default could have a material adverse effect on Borrower’s business.

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 grant a Lien 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. To Borrower’s knowledge (provided, however, such knowledge qualifier shall not apply to Eligible Accounts which are Financed Receivables), the Accounts are bona fide, existing obligations of the Account Debtors.

The Collateral is not in the possession of any third party bailee (such as a warehouse) except as otherwise provided in the Perfection Certificate or as otherwise permitted under this Agreement. None of the components of the Collateral with a value in excess of One Hundred Fifty Thousand Dollars ($150,000.00) in the aggregate shall be maintained at locations other than as provided in the Perfection Certificate or as Borrower has given Bank notice 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 with a value in excess of One Hundred Fifty Thousand Dollars ($150,000.00) in the aggregate to a bailee other than those listed on the Perfection Certificate, 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 reasonable discretion.

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

Borrower is the sole owner of its intellectual property, except for non-exclusive licenses granted to its customers in the ordinary course of business. Each patent that is material to Borrower’s business is valid and enforceable, and no part of the intellectual property that is material to Borrower’s business has been judged invalid or unenforceable, in whole or in part, and to the best of Borrower’s knowledge, no claim has been made that any part of the intellectual property violates the rights of any third party except to the extent such claim could not reasonably be expected to have a material adverse effect on Borrower’s business. 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 the Bank’s right to sell any Collateral. Borrower shall provide written notice to Bank within ten (10) days of entering or becoming bound by any such license or agreement (other than over-the-counter software that is commercially available to the public). 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.

53                                  Financed Receivables. Borrower represents and warrants for each Financed Receivable:
