5.  Grantor's Covenants.  The Grantor covenants that it shall:
(a) from time to time and at all reasonable times and upon reasonable advance notice allow the Bank, by or through any of its officers, agents, attorneys, or accountants, to examine or inspect the Collateral, and obtain valuations and audits of the Collateral, at the Grantor's reasonable expense, wherever located.  The Grantor shall do, obtain, make, execute and deliver all such additional and further acts, things, deeds, assurances and instruments as the Bank may reasonably require to vest in and assure to the Bank its rights hereunder and in or to the Collateral, and the proceeds thereof, including waivers from landlords, warehousemen and mortgagees.  The Grantor agrees that upon an Event of Default, the Bank has the right to notify (on invoices or otherwise) account debtors and other obligors or payors on any Collateral of its collateral assignment to the Bank, and that all payments thereon should be made directly to the Bank, and that the Bank has full power and authority to collect, compromise, endorse, sell or otherwise deal with the Collateral in its own name or that of the Grantor;
(b) keep the Collateral consisting of tangible personal property in commercially reasonable good order and repair at all times and immediately notify the Bank of any event causing a material loss or decline in value of the Collateral, whether or not covered by insurance, and the amount of such loss or depreciation;
(c) only use or permit the Collateral to be used in accordance with all applicable federal, state, county and municipal laws and regulations; and
(d) have and maintain insurance in commercially reasonable amounts at all times with respect to all Collateral as required in the Credit Agreement.  In the event of failure to provide insurance as provided in the Credit Agreement, the Bank may, at its option, obtain such insurance and the Grantor shall pay to the Bank, on demand, the cost thereof.  Proceeds of casualty insurance may be applied by the Bank to reduce the Liabilities or to repair or replace Collateral, all in the Bank's sole discretion.

7.  Covenants for Accounts.  If accounts are included in the definition of Collateral:
(a) The Grantor will, promptly on the Bank's demand, make notations on its books and records showing the Bank's security interest and, in connection with an audit or inspection conducted pursuant to Section 5(a) hereof, make available to the Bank shipping and delivery receipts evidencing the shipment of the goods that gave rise to an account, completion certificates or other proof of the satisfactory performance of services that gave rise to an account, a copy of the invoice for each account and copies of any written contract or order from which an account arose.  The Grantor shall promptly notify the Bank if an account becomes evidenced or secured by an instrument or chattel paper and upon the Bank's request, will promptly deliver any such instrument or chattel paper to the Bank, including any letter of credit delivered to the Grantor to support a shipment of inventory by the Grantor.

(b) The Grantor will promptly advise the Bank whenever an account debtor refuses to retain or returns any goods from the sale of which an account arose and will comply with any instructions that the Bank may give regarding the sale or other disposition of such returns.  From time to time with such frequency as the Bank may reasonably request, the Grantor will report to the Bank all credits given to account debtors on all accounts, except for those early payment discounts in the ordinary course of business.
(c) [Intentionally Reserved].
(d) At any time after the occurrence and during the continuance of an Event of Default, and without notice to the Grantor, the Bank may direct any persons who are indebted to the Grantor on any Collateral consisting of accounts or general intangibles to make payment directly to the Bank of the amounts due.  At any time after the occurrence and during the continuance of an Event of Default, the Bank is authorized to collect, compromise, endorse and sell any such Collateral in its own name or in the Grantor's name and to give receipts to such account debtors for any such payments and the account debtors will be protected in making such payments to the Bank.  Upon the Bank's written request after and during the continuance of an Event of Default, the Grantor will establish with the Bank and maintain a lockbox account ("Lockbox") with the Bank and a depository account(s) ("Cash Collateral Account") with the Bank subject to the provisions of this subparagraph and such other related agreements as the Bank may require, and the Grantor shall notify its account debtors to remit payments directly to the Lockbox.  Thereafter, funds collected in the Lockbox shall be transferred to the Cash Collateral Account, and funds in the Cash Collateral Account shall be applied by the Bank, daily, to reduce the outstanding Liabilities.
8. Further Assurances.  By its signature hereon, the Grantor hereby irrevocably authorizes the Bank to execute (on behalf of the Grantor) and file against the Grantor one or more financing, continuation or amendment statements pursuant to the UCC in form reasonably satisfactory to the Bank, and the Grantor will pay the out-of-pocket cost of preparing and filing the same in all jurisdictions in which such filing is deemed by the Bank to be necessary or desirable in order to perfect, preserve and protect its security interests.  If required by the Bank, the Grantor will execute all documentation reasonably necessary for the Bank to obtain and maintain perfection of its security interests in the Collateral.  At the Bank's request, the Grantor will execute, in form reasonably satisfactory to the Bank, a Rider to Security Agreement - Copyrights (if any Collateral consists of registered or unregistered copyrights), a Rider to Security Agreement - Patents (if any Collateral consists of patents or patent applications), a Rider to Security Agreement - Trademarks (if any Collateral consists of trademarks, tradenames, tradestyles or trademark applications).  If any Collateral consists of letter of credit rights, electronic chattel paper, deposit accounts or supporting obligations not maintained with the Bank or one of its affiliates, or any securities entitlement, securities account, commodities account, commodities contract or other investment property, then promptly after the Bank's request the Grantor will execute, and will use its commercially reasonable efforts to cause the depository institution or securities intermediary upon whose books and records the ownership interest of the Grantor in such Collateral appears, to execute such Pledge Agreements, Notification and Control Agreements or other agreements as the Bank deems necessary in order to perfect, prioritize and protect its security interest in such Collateral, in each case in a form reasonably satisfactory to the Bank.
9. Events of Default.  The Grantor shall, at the Bank's option, and under the circumstances set forth in the Credit Agreement, be in default under this Agreement upon the happening and during the continuance of any Event of Default, as that term is defined in the Credit Agreement.

10. Remedies.  Upon the occurrence of any such Event of Default and at any time during the continuance thereof, the Bank may declare all Liabilities secured hereby immediately due and payable and shall have, in addition to any remedies provided herein or by any applicable law or in equity, all the remedies of a secured party under the UCC. The Bank's remedies include, but are not limited to, the right to (a) peaceably by its own means or with judicial assistance enter the Grantor's premises and take possession of the Collateral without prior notice to the Grantor or the opportunity for a hearing, (b) render the Collateral unusable, (c) dispose of the Collateral on the Grantor's premises, (d) require the Grantor to assemble the Collateral and make it available to the Bank at a place designated by the Bank, and (e) notify the United States Postal Service to send the Grantor's mail to the Bank.  Unless the Collateral is perishable or threatens to decline speedily in value or is of a type customarily sold on a recognized market, the Bank will give the Grantor reasonable notice of the time and place of any public sale thereof or of the time after which any private sale or any other intended disposition thereof is to be made; any such sale shall be made in the manner prescribed in the UCC.  The requirements of commercially reasonable notice shall be met if such notice is sent to the Grantor at least ten (10) days before the time of the intended sale or disposition.  Expenses of retaking, holding, preparing for disposition, disposing or the like shall include the Bank's reasonable attorneys' fees and legal expenses, incurred or expended by the Bank to enforce any payment due it under this Agreement either as against the Grantor, or in the prosecution or defense of any action, or concerning any matter growing out of or connection with the subject matter of this Agreement and the Collateral pledged hereunder.  The Grantor waives all relief from all appraisement or exemption laws now in force or hereafter enacted. In exercising its remedies hereunder, the Bank will act in good faith and in a commercially reasonable manner.
11. Power of Attorney.  The Grantor does hereby make, constitute and appoint any officer or agent of the Bank as the Grantor's true and lawful attorney-in-fact, with power to (a) endorse the name of the Grantor or any of the Grantor's officers or agents upon any notes, checks, drafts, money orders, or other instruments of payment or Collateral that may come into the Bank's possession in full or part payment of any Liabilities; (b) sue for, compromise, settle and release all claims and disputes with respect to, the Collateral; and (c) sign, for the Grantor, such documentation required by the UCC, or supplemental intellectual property security agreements; granting to the Grantor's said attorney full power to do any and all things necessary to be done in and about the premises as fully and effectually as the Grantor might or could do; provided that (a), (b) and (c) only apply after an Event of Default has occurred.  The Grantor hereby ratifies all that said attorney shall lawfully do or cause to be done by virtue hereof.  This power of attorney is coupled with an interest, and is irrevocable.
12. Payment of Expenses.  At its option, after advance written notice to the Grantor, the Bank may discharge taxes, liens, security interests or such other encumbrances as may attach to the Collateral (other than Permitted Liens), and, without prior notice, may pay for required insurance on the Collateral and may pay for the maintenance, appraisal or reappraisal, and preservation of the Collateral, as determined by the Bank to be necessary.  The Grantor will reimburse the Bank on demand for any payment so made or any expense incurred by the Bank pursuant to the foregoing authorization, and the Collateral also will secure any advances or payments so made or expenses so incurred by the Bank.
13. Notices.  All notices, demands, requests, consents, approvals and other communications required or permitted hereunder ("Notices") must be in writing and will be effective upon receipt.  Notices may be given in any manner to which the parties have agreed pursuant to the Credit Agreement.
14. Preservation of Rights.  No delay or omission on the Bank's part to exercise any right or power arising hereunder will impair any such right or power or be considered a waiver of any such right or power, nor will the Bank's action or inaction impair any such right or power.  The Bank's rights and remedies hereunder are cumulative and not exclusive of any other rights or remedies which the Bank may have under other agreements, at law or in equity.

15. Illegality.  If any provision contained in this Agreement should be invalid, illegal or unenforceable in any respect, it shall not affect or impair the validity, legality and enforceability of the remaining provisions of this Agreement.
16. Changes in Writing.  No modification, amendment or waiver of, or consent to any departure by the Grantor from, any provision of this Agreement will be effective unless made in a writing signed by the Bank and the Grantor, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given.
17. Entire Agreement.  This Agreement (including the documents and instruments referred to herein) constitutes the entire agreement and supersedes all other prior agreements and understandings, both written and oral, between the parties with respect to the subject matter hereof.
18. Counterparts.  This Agreement may be signed in any number of counterpart copies and by the parties hereto on separate counterparts, but all such copies shall constitute one and the same instrument.  Delivery of an executed counterpart of signature page to this Agreement by facsimile transmission shall be effective as delivery of a manually executed counterpart.  Any party so executing this Agreement by facsimile transmission shall promptly deliver a manually executed counterpart, provided that any failure to do so shall not affect the validity of the counterpart executed by facsimile transmission.
19. Successors and Assigns.  This Agreement will be binding upon and inure to the benefit of the Grantor and the Bank and their respective heirs, executors, administrators, successors and assigns; provided, however, that the Grantor may not assign this Agreement in whole or in part without the Bank's prior written consent and the Bank at any time may assign this Agreement in whole or in part, provided such assignee assumes in writing or otherwise becomes liable for all obligations of the Bank hereunder.
