(a) Lockbox. Not later than the Seventh Amendment Effective Date, Borrower shall (i) establish a lockbox arrangement with Lender (the “Lockbox”), which shall be governed by a Master Agreement, and, within ten days after the Seventh Amendment Effective Date, shall request in writing and otherwise take such reasonable steps to ensure that all Account Debtors forward all Collections directly to the Lockbox (if Borrower fails to notify any Account Debtor to remit all such Collections to the

All Collections from sales of Inventory or from Account Debtors sent to the Lockbox shall be deposited directly on a daily basis, and in any event no later than the first Business Day after the date of receipt thereof, into the Cash Collateral Account in the identical form in which such Collections were made (except for any necessary endorsements) whether by cash or check. All amounts deposited in the Cash Collateral Account from the Lockbox or any other source shall be under the sole and exclusive control of Lender. Borrower shall have no interest in or control over such funds. The Cash Collateral Account shall not be subject to any deduction, set off, banker’s lien or any other right in favor of any Person other than Lender.

(c) Operating Account. Borrower shall maintain, in its name, an Operating Account with Lender, into which Lender shall, from time to time, deposit proceeds of Advances made to Borrower for use by Borrower in accordance with this Agreement. Unless otherwise agreed by Lender and Borrower, any Advance requested by Borrower and made under this Agreement shall be deposited into the Operating Account. Borrower shall not accumulate or maintain cash in the Operating Account or payroll or other such accounts, as of any date of determination, in excess of checks outstanding against the Controlled Disbursement Account (or Controlled Disbursement Accounts) and other Deposit Accounts approved by Lender (such as medical benefit accounts, flexible spending accounts and automated clearing house accounts) as of that date, and amounts necessary to meet minimum balance requirements.

(d) Controlled Disbursement Account. Borrower shall maintain a Controlled Disbursement Account with Lender. Borrower may maintain more than one Controlled Disbursement Account. Borrower shall base its requests for Advances on, among other things, the daily balance of the Controlled Disbursement Account (or Controlled Disbursement Accounts). Borrower shall not maintain cash in any Controlled Disbursement Account, as of any date of determination, in excess of checks outstanding against such account as of that date, and amounts necessary to meet minimum balance requirements.

(e) Lockbox and Security Accounts. The lockbox established pursuant to the Lockbox Agreement and the Cash Collateral Account, the Operating Account and the Controlled Disbursement Accounts shall be Security Accounts, with all cash, checks and other similar items of payment in such accounts securing payment of the Indebtedness.

(f) Costs of Collection. All service charges and costs related to the establishment and maintenance of the Security Accounts shall be the sole responsibility

of Borrower, whether the same are incurred by Lender or Borrower. Borrower hereby indemnifies and holds Lender harmless from and against any loss or damage with respect to any deposits made in the Security Accounts which are dishonored or returned for any reason. If any deposits are dishonored or returned unpaid for any reason, Lender, in its sole discretion, may charge the amount thereof against the Cash Collateral Account or any other Security Account or other Deposit Account of Borrower. Lender shall not be liable for any loss or damage resulting from any error, omission, failure or negligence on the part of Lender, except losses or damages resulting from Lender’s gross negligence or willful misconduct, as determined by a final judgment of a court of competent jurisdiction.

(g) Return of Funds. Upon the payment in full of the Indebtedness (other than continuing indemnification obligations) and the termination of any commitment to lend by Lender hereunder, (i) Lender’s security interests and other rights in funds in the Security Accounts shall terminate, (ii) all rights to such funds shall revert to Borrower, and (iii) Lender will, at Borrower’s expense, take such steps as Borrower may reasonably request to evidence the termination of such security interests and to effect the return to Borrower of such funds.

(h) Attorney-in-Fact to Endorse Documents. Lender, or Lender’s designated agent, is hereby constituted and appointed attorney-in-fact for Borrower with authority and power to endorse any and all instruments, documents, and chattel paper upon the failure of Borrower to do so. Such authority and power, being coupled with an interest, shall be (i) irrevocable until all of the Indebtedness is paid, (ii) exercisable by Lender at any time and without any request upon Borrower by Lender to so endorse, and (iii) exercisable in the name of Lender or Borrower. Borrower hereby waives presentment, demand, notice of dishonor, protest, notice of protest, and any and all other similar notices with respect thereto, regardless of the form of any endorsement thereof. Lender shall not be bound or obligated to take any action to preserve any rights therein against prior parties thereto.

RECORD OF ADVANCES; APPLICATION OF COLLECTIONS.

(a) Maintenance of Record of Advances. Lender shall maintain records in respect of Borrower that shall reflect (i) the aggregate outstanding principal amount of Loans and accrued interest, and (ii) all other Indebtedness that shall have become payable hereunder (the “Advance Record”). Each entry by Lender in the Advance Record shall be, to the extent permitted by applicable law and absent manifest error, prima facie evidence of the data entered. Such entries by Lender shall not be a condition to Borrower’s obligation to repay the Indebtedness.

(b) Charges, Credits and Reports. Borrower hereby authorizes Lender to charge the Advance Record with all Loans and all other Indebtedness and other obligations of Borrower to Lender. The Advance Record will be credited in accordance with the provisions of this Agreement with all payments received by Lender directly from Borrower or otherwise for the account of Borrower pursuant to this Agreement.

Lender shall send Borrower monthly statements in accordance with Lender’s standard procedures. Any and all such periodic or other statements or reconciliations of the Advance Record shall be final, binding and conclusive upon Borrower in all respects, absent manifest error, unless Lender receives specific written objection thereto from Borrower within thirty (30) Business Days after such statements or reconciliation shall have been received by Borrower.

(c) Application of Specific Payments. Except for the crediting to the Advance Record of Collections deposited to the Cash Collateral Account as provided below, Borrower shall make all other payments to be made by Borrower under this Agreement with respect to the Indebtedness not later than 2:00 P.M. (Eastern time) on the day when due, without setoff, counterclaim, defense or deduction of any kind. Payments received after 2:00 P.M. (Eastern time) shall be deemed to have been received on the next Business Day. Prior to the occurrence of an Event of Default, Borrower may specify to Lender the Indebtedness to which such payment is to be applied. If Borrower does not specify an application for such payment or if an Event of Default has occurred, Lender shall apply such payment in its discretion.

(d) Crediting of Collections. For the purpose of calculating interest on the Indebtedness and determining the aggregate amount of Loans outstanding and the availability for additional Loans, all Collections shall be credited to the account of Borrower (as reflected in the Advance Record) on the next Business Day after the Business Day on which Lender has received notice of the deposit of the proceeds of such Collections into the Cash Collateral Account (including automated clearinghouse and federal wire transfers); provided that, immediately available funds shall be applied on the same Business Day. Collections shall be credited as follows: (i) first to any costs and expenses due under this Agreement, (ii) second to the Loans. From time to time, upon advance written notice to Borrower, Lender may adopt such additional or modified regulations and procedures as Lender may deem reasonable and appropriate with respect to the operation of the Cash Collateral Account and not substantially inconsistent with the terms of this Agreement.

(e) Application of Deposits in Cash Collateral Account. Deposits of Collections to the Cash Collateral Account shall be credited to the Advance Record of Borrower in accordance with subsection (d) above, and thereby reduce the principal outstanding on the Loans as Lender may choose, in its reasonable credit judgment.

8. Amendment to Unused Fee. The Third Amendment to Loan Agreement and Allonge to Promissory Note, dated August 9, 2005, by and between Borrower and Lender, is hereby amended to delete the Unused Line of Credit Fee section therefrom and to insert in place thereof the following:

Borrower shall pay to Lender, as a consideration for the Lender’s commitment to lend under this Agreement, a commitment fee from the Seventh Amendment Effective Date through the Expiration Date, payable monthly, at a rate per annum equal to (a) one-eight percent (1/8%) per annum, multiplied by (b) (i) the

average daily Maximum Revolving Amount in effect during such month, minus (ii) the average daily borrowings of Borrower under this Agreement during such month. The commitment fee shall be payable in arrears on the first Business Day of each calendar month, and on the Expiration Date.

9. Waiver of Specific Covenants. Borrower has notified Lender that Borrower has failed to comply with the Operating Cash Flow to Fixed Charge Ratio financial covenant set forth in the Financial Covenants section of the Loan Agreement for the period ending June 30, 2007 (the “Violation”). Borrower has requested that Lender waive the Default and Event of Default that exists solely by virtue of the Violation. Lender hereby waives the aforesaid Default and Event of Default on the conditions that, after giving effect to the terms of this Amendment, no Default or Event of Default shall exist under the Loan Agreement or any other Related Document as of the Seventh Amendment Effective Date. This Amendment shall serve as evidence of such waiver.

This payment due on November 15, 2007, will be for all principal and all accrued interest not yet paid. In addition, Borrower will pay regular monthly payments of all accrued unpaid interest due as of each payment date, beginning September 1, 2007, with all subsequent interest payments to be due on the same day of each month after that. Unless otherwise agreed or required by applicable law, payments will be applied first to any accrued unpaid interest; then to principal; then to any unpaid collection costs; and then to any late charges. The annual interest rate for this Note is computed on a 365/360 basis; that is, by applying the ratio of the annual interest rate over a year of 360 days, multiplied by the outstanding principal balance, multiplied by the actual number of days the principal balance is outstanding. Borrower will pay Lender at Lender’s address shown above or at such other place as Lender may designate in writing.

VARIABLE INTEREST RATE. The interest rate on this Note is subject to change from time to time based on changes in an index which is the Prime Rate announced by Lender (the “Index”).

If the Index becomes unavailable during the term of this loan, Lender may designate a substitute index after notifying Borrower. Lender will tell Borrower the current Index rate upon Borrower’s request. The interest rate change will not occur more often than each day that the Index changes. The interest rate will change automatically and correspondingly on the date of each announced change of the Index by Lender. Borrower understands that Lender may make loans based on other rates as well. The Index currently is 8.25% per annum. The interest rate to be applied to the unpaid principal balance of this Note will be at a rate of 0.250 percentage points under the Index, resulting in an initial rate of 8.00% per annum. NOTICE: Under no circumstances will the interest rate on this Note be more than the maximum rate allowed by applicable law.

PREPAYMENT. Borrower agrees that all loan fees and other prepaid finance charges are earned fully as of the date of the loan and will not be subject to refund upon early payment (whether voluntary or as a result of default), except as otherwise required by law. Except for the foregoing, Borrower may pay without penalty all or a portion of the amount owed earlier than it is due. Early payments will not, unless agreed to by Lender in writing, relieve Borrower of Borrower’s obligation to continue to make payments under the payment schedule. Rather, early payments will reduce the principal balance due. Borrower agrees not to send Lender payments marked “paid in full”, “without recourse”, or similar language. If Borrower sends such a payment, Lender may accept it without losing any of Lender’s rights under this Note, and Borrower will remain obligated to pay any further amount owed to Lender. All written communications concerning disputed amounts, including any check or other payment instrument that indicates that the payment constitutes “payment in full” of the amount owed or that is tendered with other conditions or limitations or as full satisfaction of a disputed amount must be mailed or delivered to: KeyBank National Association, 000 Xxxxxx Xxxxxx, Xxxxxxxxx, Xxxx 00000.
