effect on the value of the Intellectual Property Collateral. To the knowledge of such Debtor, the right, title and interest of the applicable Debtor in, to and under each Patent License, Copyright License and Trademark License constituting Intellectual Property Collateral is not subject to any defense, offset, counterclaim or claim.

In the case of all such insurance policies, each such Debtor shall designate the Agent, as mortgagee or lender loss payee and such policies shall provide that any loss be payable to the Agent, as mortgagee or lender loss payee, as its interests may appear. Further, upon the request of the Agent, each such Debtor shall deliver certificates evidencing such policies, including all endorsements thereon and those required hereunder, to Agent; and each such Debtor assigns to Agent, as additional security hereunder, all its rights to receive proceeds of insurance with respect to the Collateral. All such insurance shall, by its terms, provide that the applicable carrier shall, prior to any cancellation before the expiration date thereof, mail thirty (30) days’ prior written notice to the Agent of such cancellation. Each Debtor further shall provide Agent upon request with evidence reasonably satisfactory to Agent that each such Debtor is at all times in compliance with this paragraph. Upon the occurrence and during the continuance of a Default or an Event of Default, Agent may act as each such Debtor’s attorney-in-fact in obtaining, adjusting, settling and compromising such insurance and endorsing any drafts. Upon such Debtor’s failure to insure the Collateral as required in this covenant, Agent may procure such insurance and its costs therefor shall be charged to such Debtor, payable on demand, with interest at the highest rate set forth in the Credit Agreement and added to the Indebtedness secured hereby. The disposition of proceeds payable to such Debtor of any insurance on the Collateral (the “Insurance Proceeds”) shall be governed by the following:

(a) provided that no Default or Event of Default has occurred and is continuing hereunder, (a) if the amount of Insurance Proceeds in respect of any loss or casualty does not exceed One Hundred Thousand Dollars ($100,000), such Debtor shall be entitled, in the event of such loss or casualty, to receive all such Insurance Proceeds and to apply the same toward the replacement of the Collateral affected thereby or to the purchase of other assets to be used in such Debtor’s business (provided that such assets shall be subjected to a first lien in favor of Agent); and (b) if the amount of Insurance Proceeds in respect of any loss or casualty exceeds One Hundred Thousand Dollars ($100,000), such Insurance Proceeds shall be paid to and received by Agent, for release to such Debtor for the replacement of the Collateral affected thereby or to the purchase of other assets to be used in such Debtor’s business (provided that such assets shall be subjected to a first lien in favor of Agent); or, upon written request of such Debtor (accompanied by reasonable supporting documentation), for such other use or purpose as approved by the Majority Banks, in their reasonable discretion, it being understood and agreed in connection with any release of funds under this subparagraph (b), that the Agent and the Majority Banks may impose reasonable and customary conditions on the disbursement of such Insurance Proceeds; and

(b) if a Default or Event of Default has occurred or is continuing and is not waived as provided in the Credit Agreement, all Insurance Proceeds in respect of any loss or casualty shall be paid to and received by the Agent, to be applied by the Agent against the Indebtedness and/or to be held by the Agent as cash collateral for the Indebtedness, as the Majority Banks may direct in their sole discretion.

Section 4.6 Furnishing of Information and Inspection Rights. Each Debtor will, at any time and from time to time during regular business hours, upon reasonable advance notice (except if any Default or Event of Default has occurred and is continuing, when no prior notice shall be required), permit the Agent, or its agents or representatives, to examine and make copies of and abstracts from all Records, to visit the offices and properties of such Debtor for the purpose of examining such Records, and to discuss matters relating to Debtor’s performance hereunder and under the other Credit Agreement with any of the officers, directors, employees or independent public accountants of such Debtor having knowledge of such matters; provided, however, that the Agent acknowledges that, in exercising the rights and privileges conferred in this Section 4.6, it or its agents and representatives may, from time to time, obtain knowledge of information, practices, books, correspondence and records of a confidential nature and in which such Debtor has a proprietary interest. The Agent agrees that all such information, practices, books, correspondence and records are to be regarded as confidential information and agrees that it shall be subject to Section 14.11 of the Credit Agreement. Notwithstanding anything to the contrary in this Agreement or in Section 14.11 of the Credit Agreement, the Agent may reply to a request from any Person for information related to any Collateral referred to in any financing statement filed to perfect the security interest and liens established hereby, to the extent necessary to maintain the perfection or priority of such security interests or liens, or otherwise required under applicable law. Furthermore, such Debtor shall permit the Agent and its representatives to examine, inspect and audit the Collateral and to examine, inspect and audit such Debtor’s books and Records to the extent provided under the Credit Agreement.

Section 4.7 Corporate Changes. Each Debtor shall not change its name, identity, corporate structure or jurisdiction of organization in any manner that might make any financing statement filed in connection with this Agreement seriously misleading within the meaning of Section 9-506 of the UCC unless such Debtor shall have given the Agent thirty (30) days prior written notice with respect to any change in such Debtor’s corporate structure, jurisdiction of organization, name or identity and shall have taken all action deemed reasonably necessary by the Agent under the circumstances to protect its Liens and the perfection and priority thereof. Such Debtor shall give prompt written notice of any change in its principal place of business, chief executive office or place where it keeps its books and records.

(b) Each Debtor shall maintain the Equipment and Inventory in accordance with the terms of the Credit Agreement.

Section 4.10 Notification. Each Debtor shall promptly notify the Agent in writing of any Lien, encumbrance or claim (other than a Permitted Lien or other Liens permitted under Section 8.2 of the Credit Agreement, to the extent not otherwise subject to any notice requirements under the Credit Agreement) that has attached to or been made or asserted against any of the Collateral upon becoming aware of the existence of such Lien, encumbrance or claim.

Section 4.11 Collection of Accounts. So long as no Default or Event of Default has occurred and is continuing and except as otherwise provided in this Section 4.11 and Section 6.3, each Debtor shall have the right to collect and receive payments on its Accounts, and to use and expend the same in its operations in each case in compliance with the terms of each of the Credit Agreement.

issuing any of the Pledged Shares and any and all rights of conversion, exchange, subscription or any other rights, privileges or options pertaining to any of the Pledged Shares as if the Agent were the absolute owner thereof, including, without limitation, the right to exchange, at its discretion, any and all of the Pledged Shares upon the merger, consolidation, reorganization, recapitalization or other readjustment of any corporation issuing any of such Pledged Shares or upon the exercise by any such issuer or the Agent of any right, privilege or option pertaining to any of the Pledged Shares, and in connection therewith, to deposit and deliver any and all of the Pledged Shares with any committee, depositary, transfer Agent, registrar or other designated agency upon such terms and conditions as the Agent may determine, all without liability except to account for property actually received by it, but the Agent shall have no duty to exercise any of the aforesaid rights, privileges or options, and the Agent shall not be responsible for any failure to do so or delay in so doing.

(ii) All rights of such Debtor to exercise the voting and other consensual rights which it would otherwise be entitled to exercise pursuant to Subsection 4.12(a)(i) and to receive the dividends, interest and other distributions which it would otherwise be authorized to receive and retain pursuant to Subsection 4.12(a)(ii) shall be suspended until such Default or Event of Default shall no longer exist, and all such rights shall, until such Default or Event of Default shall no longer exist, thereupon become vested in the Agent which shall thereupon have the sole right to exercise such voting and other consensual rights and to receive, hold and dispose of as Pledged Shares such dividends, interest and other distributions.

(iii) All dividends, interest and other distributions which are received by such Debtor contrary to the provisions of this Subsection 4.12(b) shall be received in trust for the benefit of the Agent, shall be segregated from other funds of such Debtor and shall be forthwith paid over to the Agent as Collateral in the same form as so received (with any necessary endorsement).

Without limiting the generality of the foregoing, the Agent may (A) without demand or notice to the Debtors (except as required under the Credit Agreement or applicable law), collect, receive or take possession of the Collateral or any part thereof, and for that purpose the Agent (and/or its Agents, servicers or other independent contractors) may enter upon any premises on which the Collateral is located and remove the Collateral therefrom or render it inoperable, and/or (B) sell, lease or otherwise dispose of the Collateral, or any part thereof, in one or more parcels at public or private sale or sales, at the Agent’s offices or elsewhere, for cash, on credit or for future delivery, and upon such other terms as the Agent may, in its reasonable discretion, deem commercially reasonable or otherwise as may be permitted by law. The Agent and, subject to the terms of the Credit Agreement, each of the Banks shall have the right at any public sale or sales, and, to the extent permitted by applicable law, at any private sale or sales, to bid (which bid may be, in whole or in part, in the form of cancellation of indebtedness) and become a purchaser of the Collateral or any part thereof free of any right of redemption on the part of the Debtors, which right of redemption is hereby expressly waived and released by the Debtors to the extent permitted by applicable law. The Agent may require the Debtors to assemble the Collateral and make it available to the Agent at any place designated by the Agent to allow Agent to take possession or dispose of such Collateral. The Debtors agree that the Agent shall not be obligated to give more than five (5) days prior written notice

of the time and place of any public sale or of the time after which any private sale may take place and that such notice shall constitute reasonable notice of such matters. The foregoing shall not require notice if none is required by applicable law. The Agent shall not be obligated to make any sale of Collateral if, in the exercise of its reasonable discretion, it shall determine not to do so, regardless of the fact that notice of sale of Collateral may have been given. The Agent may, without notice or publication (except as required by applicable law), adjourn any public or private sale or cause the same to be adjourned from time to time by announcement at the time and place fixed for sale, and such sale may, without further notice, be made at the time and place to which the same was so adjourned. The Debtors shall be liable for all reasonable expenses of retaking, holding, preparing for sale or the like, and all reasonable attorneys’ fees, legal expenses and other costs and expenses incurred by the Agent in connection with the collection of the Indebtedness and the enforcement of the Agent’s rights under this Agreement and the Credit Agreement. The Debtors shall, to the extent permitted by applicable law, remain liable for any deficiency if the proceeds of any such sale or other disposition of the Collateral (conducted in conformity with this clause (ii) and applicable law) applied to the Indebtedness are insufficient to pay the Indebtedness in full. The Agent shall apply the proceeds from the sale of the Collateral hereunder against the Indebtedness in such order and manner as provided in the Credit Agreement.

(c) The Agent may cause any or all of the Collateral held by it to be transferred into the name of the Agent or the name or names of the Agent’s nominee or nominees.

(d) The Agent may exercise any and all rights and remedies of the Debtors under or in respect of the Collateral, including, without limitation, any and all rights of the Debtors to demand or otherwise require payment of any amount under, or performance of any provision of any of the Collateral and any and all voting rights and corporate powers in respect of the Collateral.

(e) On any sale of the Collateral, the Agent is hereby authorized to comply with any limitation or restriction with which compliance is necessary (based on a reasoned opinion of the Agent’s counsel) in order to avoid any violation of applicable law or in order to obtain any required approval of the purchaser or purchasers by any applicable Governmental Authority.

(f) The Agent may direct account debtors and any other parties liable for any payment under any of the Collateral to make payment of any and all monies due and to become due thereunder directly to the Agent or as the Agent shall direct.

(g) In the event of any sale, assignment or other disposition of the Intellectual Property Collateral, the goodwill of the business connected with and symbolized by any Trademark Collateral subject to such disposition shall be included, and the Debtors shall supply to the Agent or its designee the Debtors’ know-how and expertise related to the Intellectual Property Collateral subject to such disposition, and the Debtors’ notebooks, studies, reports, records, documents and things embodying the same or relating to the inventions, processes or ideas covered by and to the manufacture of any products under or in connection with the Intellectual Property Collateral subject to such disposition.

(h) For purposes of enabling the Agent to exercise its rights and remedies under this Section 6.1 and enabling the Agent and its successors and assigns to enjoy the full benefits of the Collateral, the Debtors hereby grant to the Agent an irrevocable, nonexclusive license (exercisable without payment of royalty or other compensation to the Debtors) to use, assign, license or sublicense any of the Intellectual Property Collateral, Computer Records or Software (including in such license reasonable access to all media in which any of the licensed items may be recorded or stored and all computer programs used for the completion or printout thereof), exercisable upon the occurrence and during the continuance of an Event of Default (and thereafter if Agent succeeds to any of the Collateral pursuant to an enforcement proceeding or voluntary arrangement with Debtor), except as may be prohibited by any licensing agreement relating to such Computer Records or Software. This license shall also inure to the benefit of all successors, assigns, transferees of and purchasers from the Agent.

Section 6.2 Private Sales.

(a) In view of the fact that applicable securities laws may impose certain restrictions on the method by which a sale of the Pledged Shares may be effected after an Event of Default, Debtors agree that upon the occurrence and during the continuance of an Event of Default, Agent may from time to time attempt to sell all or any part of the Pledged Shares by a private sale in the nature of a private placement, restricting the bidders and prospective purchasers to those who will represent and agree that they are “accredited investors” within the meaning of Regulation D promulgated pursuant to the Securities Act of 1933, as amended (the “Securities Act”), and are purchasing for investment only and not for distribution. In so doing, Agent may solicit offers for the Pledged Shares, or any part thereof, from a limited number of investors who might be interested in purchasing the Pledged Shares. Without limiting the methods or manner of disposition which could be determined to be commercially reasonable, if Agent hires a firm of regional or national reputation that is engaged in the business of rendering investment banking and brokerage services to solicit such offers and facilitate the sale of the Pledged Shares, then Agent’s acceptance of the highest offer (including its own offer, or the offer of any of the Banks at any such sale) obtained through such efforts of such firm shall be deemed to be a commercially reasonable method of disposition of such Pledged Shares. The Agent shall not be under any obligation to delay a sale of any of the Pledged Shares for the period of time necessary to permit the issuer of such securities to register such securities under the laws of any jurisdiction outside the United States, under the Securities Act or under any applicable state securities laws, even if such issuer would agree to do so.

(b) The Debtors further agree to do or cause to be done, to the extent that the Debtors may do so under applicable law, all such other reasonable acts and things as may be necessary to make such sales or resales of any portion or all of the Collateral valid and binding and in compliance with any and all applicable laws, regulations, orders, writs, injunctions, decrees or awards of any and all courts, arbitrators or governmental instrumentalities, domestic or foreign, having jurisdiction over any such sale or sales, all at the Debtors’ expense.

Section 6.3 Establishment of Cash Collateral Account; and Lock Box.

(a) Immediately upon the occurrence and during the continuance of an Event of Default (without the necessity of any notice hereunder), there shall be established by each Debtor with Agent, for the benefit of the Banks in the name of the Agent, a segregated non-interest bearing cash collateral account (the “Cash Collateral Account”) bearing a designation clearly indicating that the funds deposited therein are held for the benefit of the Agent and the Banks; provided, however, that the Cash Collateral Account may be an interest-bearing account with a commercial bank (including Comerica or any other Bank which is a commercial bank) if determined by the Agent, in its reasonable discretion, to be practicable, invested by Agent in its sole discretion, but without any liability for losses or the failure to achieve any particular rate of return. Furthermore, in connection with the establishment of a Cash Collateral Account under the first sentence of this Section 6.3 (and on the terms and within the time periods provided thereunder), (i) each Debtor agrees to establish and maintain (and Agent, acting at the request of the Banks, may establish and maintain) at Debtor’s sole expense a United States Post Office lock box (the “Lock Box”), to which Agent shall have exclusive access and control. Each Debtor expressly authorizes Agent, from time to time, to remove the contents from the Lock Box for disposition in accordance with this Agreement; and (ii) each Debtor shall notify all account debtors that all payments made to Debtor (a) other than by electronic funds transfer, shall be remitted, for the credit of Debtor, to the Lock Box, and Debtor shall include a like statement on all invoices, and (b) by electronic funds transfer, shall be remitted to the Cash Collateral Account, and Debtor shall include a like statement on all invoices. Each Debtor agrees to execute all documents and authorizations as reasonably required by the Agent to establish and maintain the Lock Box and the Cash Collateral Account. It is acknowledged by the parties hereto that any lockbox presently maintained or subsequently established by a Debtor with Agent may be used, subject to the terms hereof, to satisfy the requirements set forth in the first sentence of this Section 6.3.

(b) Immediately upon the occurrence and during the continuance of an Event of Default, any and all cash (including amounts received by electronic funds transfer), checks, drafts and other instruments for the payment of money received by each Debtor at any time, in full or partial payment of any of the Collateral consisting of Accounts or Inventory, shall forthwith upon receipt be transmitted and delivered to Agent, properly endorsed, where required, so that such items may be collected by Agent. Any such amounts and other items received by a Debtor shall not be commingled with any other of such Debtor’s funds or property, but will be held separate and apart from such Debtor’s own funds or property, and upon express trust for the benefit of Agent until delivery is made to Agent. All items or amounts which are remitted to a Lock Box or otherwise delivered by or for the benefit of a Debtor to Agent on account of partial or full payment of, or any other amount payable with respect to, any of the Collateral shall, at Agent’s option, be applied to any of the Indebtedness, whether then due or not, in the order and manner set forth in the Credit Agreement. No Debtor shall have any right whatsoever to withdraw any funds so deposited. Each Debtor further grants to Agent a first security

interest in and lien on all funds on deposit in such account. Each Debtor hereby irrevocably authorizes and directs Agent to endorse all items received for deposit to the Cash Collateral Account, notwithstanding the inclusion on any such item of a restrictive notation, e.g., “paid in full”, “balance of account”, or other restriction.

Section 6.4 Default Under Credit Agreement. Subject to any applicable notice and cure provisions contained in the Credit Agreement, the occurrence of any Event of Default (as defined in the Credit Agreement), including without limit a breach of any of the provisions of this Agreement, shall be deemed to be an Event of Default under this Agreement. This Section 6.4 shall not limit the Events of Default set forth in the Credit Agreement.
