11

(h) Accounts and Contracts. Each Debtor shall, in accordance with its usual business practices in effect from time to time, endeavor to collect or cause to be collected from each account debtor under its Accounts, as and when due, any and all amounts owing under such Accounts.

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 the Agent upon request with evidence reasonably satisfactory to the Agent that each such Debtor is at all times in compliance with this

12

paragraph. Upon the occurrence and during the continuance of a Default or an Event of Default, the Agent may, at its option, 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, the Agent may, at its option, 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, (i) 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 priority Lien in favor of the Agent and such repurchase of assets shall occur within 180 days of such Debtor receiving the Insurance Proceeds); and (ii) 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 the 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 priority Lien in favor of the Agent); or, upon written request of such Debtor (accompanied by reasonable supporting documentation), for such other use or purpose as approved by the Agent in its reasonable discretion, it being understood and agreed in connection with any release of funds under this subparagraph (ii), that the Agent may impose reasonable and customary conditions on the disbursement of such Insurance Proceeds; provided further that if such proceeds are not, as applicable, used by the Debtors to repurchase assets or released by the Agent to the Debtors under this clause (a) within 180 days, or if at any time prior to the end of such 180 day period, a Default or Event of Default has occurred, such proceeds shall be applied to the Indebtedness in accordance with clause (b) below; 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 in the manner specified in the Credit Agreement.

Section 4.5 Corporate Changes; Books and Records; Inspection Rights. (a) No Debtor shall change its respective name, identity, corporate structure or jurisdiction of organization, or identification number 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, (b) each Debtor shall keep the Records at the location specified on Schedule 3.2 as the location of such books and records or as otherwise specified in writing to the Agent and (c) the Debtors shall permit the Agent, the Lenders, and their respective agents and representatives to conduct inspections, discussion and audits of the Collateral in accordance with the terms of the Credit Agreement.

Section 4.6 Notification of Lien; Continuing Disclosure. (a) Each Debtor shall promptly notify the Agent in writing of any Lien, encumbrance or claim (other than a Permitted Lien, 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; and (b) concurrently with delivery of the Covenant Compliance Report for each fiscal year, Debtors shall execute and deliver to the Agent a Collateral Compliance Report in the form attached hereto as Exhibit C.

(A) Each Debtor shall be entitled to exercise any and all voting and other consensual rights (including, without limitation, the right to give consents, waivers and ratifications) pertaining to any of the Pledged Shares or any part thereof; provided, however, that no vote shall be cast or consent, waiver or ratification given or action taken without the prior written consent of the Agent which would violate any provision of this Agreement or the Credit Agreement; and

(B) Except as otherwise provided by the Credit Agreement, such Debtor shall be entitled to receive and retain any and all dividends, distributions and interest paid in respect to any of the Pledged Shares.

(ii) Upon the occurrence and during the continuance of a Default or an Event of Default:

(A) The Agent may, without notice to such Debtor, transfer or register in the name of the Agent or any of its nominees, for the equal and ratable benefit of the Lenders, any or all of the Pledged Shares and the Proceeds thereof (in cash or otherwise) held by the Agent hereunder, and the Agent or its nominee may thereafter, after delivery of notice to such Debtor, exercise all voting and corporate rights at any meeting of any corporation 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.

(B) All rights of such Debtor to exercise the voting and other consensual rights which it would otherwise be entitled to exercise pursuant to Section 4.7(a)(i)(A) and to receive the dividends, interest and other distributions which it would otherwise be authorized to receive and retain pursuant to Section 4.7(a)(i)(B) 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.

(C) All dividends, interest and other distributions which are received by such Debtor contrary to the provisions of this Section 4.7(a)(ii) 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).

(D) Each Debtor shall execute and deliver (or cause to be executed and delivered) to the Agent all such proxies and other instruments as the Agent may reasonably

14

request for the purpose of enabling the Agent to exercise the voting and other rights which it is entitled to exercise pursuant to this Section 4.7(a)(ii) and to receive the dividends, interest and other distributions which it is entitled to receive and retain pursuant to this Section 4.7(a)(ii). The foregoing shall not in any way limit the Agent’s power and authority granted pursuant to the other provisions of this Agreement.

(b) Possession; Reasonable Care. Regardless of whether a Default or an Event of Default has occurred or is continuing, the Agent shall have the right to hold in its possession all Pledged Shares pledged, assigned or transferred hereunder and from time to time constituting a portion of the Collateral. The Agent may appoint one or more agents (which in no case shall be a Debtor or an affiliate of a Debtor) to hold physical custody, for the account of the Agent, of any or all of the Collateral. The Agent shall be deemed to have exercised reasonable care in the custody and preservation of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which the Agent accords its own property, it being understood that the Agent shall not have any responsibility for (i) ascertaining or taking action with respect to calls, conversions, exchanges, maturities, tenders or other matters relative to any Collateral, whether or not the Agent has or is deemed to have knowledge of such matters, or (ii) taking any necessary steps to preserve rights against any parties with respect to any Collateral, except, subject to the terms hereof, upon the written instructions of the Lenders. Following the occurrence and continuance of an Event of Default, the Agent shall be entitled to take ownership of the Collateral in accordance with the UCC.

Such Debtor hereby (x) authorizes the Agent to attach each such amendment to this Agreement, (y) agrees that all such shares of stock, membership interests, partnership units, notes or instruments listed in any such amendment delivered to the Agent shall for all purposes hereunder constitute Pledged Shares, and (z) is deemed to have made, upon the delivery of each such amendment, the representations and warranties contained in Section 3.4 of this Agreement with respect to the Collateral covered thereby.

Except as otherwise expressly permitted by the terms of the Credit Agreement relating to disposition of assets and except for Permitted Liens (except for Pledged Shares, over which the only Lien shall be that Lien established under this Agreement), each Debtor agrees to maintain and preserve the Agent’s security interest in and pledge and collateral assignment of the Collateral hereunder and the priority thereof.

(b) Each Debtor hereby irrevocably authorizes the Agent at any time and from time to time to file in any filing office in any jurisdiction any initial financing statements and amendments thereto that (i) indicate any or all of the Collateral upon which the Debtors have granted a Lien, and (ii) provide any other information required by Part 5 of Article 9 of the UCC, including organizational information and in the case of a fixture filing or a filing for Collateral consisting of as-extracted collateral or timber to be cut, a sufficient description of real property to which the Collateral relates. Each Debtor agrees to furnish any such information required by the preceding paragraph to the Agent promptly upon request.

If any Debtor shall fail to perform any covenant or agreement contained in this Agreement, the Agent may (but shall not be obligated to) perform or attempt to perform such covenant or agreement on behalf of the Debtors, in which case Agent shall exercise good faith and make diligent efforts to give Debtors prompt prior written notice of such performance or attempted performance. In such event, the Debtors shall, at the request of the Agent, promptly pay any reasonable amount expended by the Agent in connection with such performance or attempted performance to the Agent, together with interest thereon at the interest rate set forth in the Credit Agreement, from and including the date of such expenditure to but excluding the date such expenditure is paid in full.

The Debtors shall pay or reimburse the Agent within five (5) Business Days after demand for all reasonable costs and expenses (including reasonable attorney’s and paralegal fees) incurred by it in connection with the enforcement, attempted enforcement, or preservation of any rights or remedies under this Agreement or any other Loan Document during the existence of an Event of Default or after acceleration of any of the Indebtedness (including in connection with any “workout” or restructuring regarding the Indebtedness, and including in any insolvency proceeding or appellate proceeding). The agreements in this Section 5.5 shall survive the payment in full of the Indebtedness. Notwithstanding the foregoing, the reimbursement of any fees and expenses incurred by the Lenders shall be governed by the terms and conditions of the Credit Agreement.

Section 5.6 Indemnification. The Debtors shall indemnify, defend and hold the Agent, and each Lender and each of their respective officers, directors, employees, counsel, agents and attorneys-in-fact (each, an “Indemnified Person”) harmless from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, charges, expenses and disbursements (including reasonable attorneys’ and paralegals’ fees) of any kind or nature whatsoever which may at any time (including at any time following repayment of the Indebtedness and the termination, resignation or replacement of the Agent or replacement of any Lender) be imposed on, incurred by or asserted against any such Indemnified Person in any way relating to or arising out of this Agreement or any other Loan Document or any document relating to or arising out of or referred to in this Agreement or any other Loan Document, or the transactions contemplated hereby, or any action taken or omitted by any such Indemnified Person under or in connection with any of the foregoing, including with respect to any investigation, litigation or proceeding (including any bankruptcy proceeding or appellate proceeding) related to or arising out of this Agreement or the Indebtedness or the use of the proceeds thereof, whether or not any Indemnified Person is a party thereto (all the foregoing, collectively, the “Indemnified Liabilities”); provided, that the Debtors shall have no obligation under this Section 5.6 to any Indemnified Person with respect to Indemnified Liabilities to the extent resulting from the gross negligence or willful misconduct of such Indemnified Person. The agreements in this Section 5.6 shall survive payment of all other Indebtedness.

ARTICLE 6

Default

Section 6.1 Rights and Remedies. If an Event of Default shall have occurred and be continuing, the Agent shall have the following rights and remedies subject to the direction and/or consent of the Lenders as required under the Credit Agreement:

(a) The Agent may exercise any of the rights and remedies set forth in this Agreement (including, without limitation, Article 5 hereof), in the Credit Agreement, or in any other Loan Document, or by applicable law.

(b) In addition to all other rights and remedies granted to the Agent in this Agreement, the Credit Agreement or by applicable law, the Agent shall have all of the rights and remedies of a secured party under the UCC (whether or not the UCC applies to the affected Collateral) and the Agent may also, without previous demand or notice except as specified below or in the Credit Agreement, sell the Collateral or any part thereof in one or more parcels at public or private sale, at any exchange, broker’s board or at any of 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,

18

deem commercially reasonable or otherwise as may be permitted by law. Without limiting the generality of the foregoing, the Agent may (i) 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 (ii) 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 Lenders 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 the 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 Collateral subject to such disposition shall be included, and the Debtors shall supply to the Agent or its designee the

19

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 a Default or an Event of Default (and thereafter if Agent succeeds to any of the Collateral pursuant to an enforcement proceeding or voluntary arrangement with Debtors), 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, the 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, the 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 the 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 the Agent’s acceptance of the highest offer (including its own offer, or the offer of any of the Lenders 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) Notwithstanding anything to the contrary in this Agreement, in the case of any Event of Default under Section 9.1(i) of the Credit Agreement, immediately following the occurrence thereof, and in the case of any other Event of Default, (w) upon the termination of any commitments to extend credit under the Credit Agreement, (x) upon the acceleration of any Indebtedness arising under the Credit Agreement, (y) at the option of Agent or (z) upon the request of the Majority Lenders after

20

the commencement of any remedies hereunder, there shall be established by each Debtor with the Agent, for the benefit of the Lenders 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 Lenders; provided, however, that the Cash Collateral Account may be an interest-bearing account with a commercial bank (including Comerica or any other Lender which is a commercial bank) if determined by the Agent, in its reasonable discretion, to be practicable, invested by the 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 the Agent, acting at the request of the Lenders, may establish and maintain) at such Debtor’s sole expense a United States Post Office lock box (the “Lock Box”), to which the Agent shall have exclusive access and control. Each Debtor expressly authorizes the 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 such Debtor (a) other than by electronic funds transfer, shall be remitted, for the credit of such Debtor, to the Lock Box, and such Debtor shall include a like statement on all invoices, and (b) by electronic funds transfer, shall be remitted to the Cash Collateral Account, and such 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 the 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) Notwithstanding anything to the contrary in this Agreement, in the case of any Event of Default under Section 9.1(i) of the Credit Agreement, immediately following the occurrence thereof, and in the case of any other Event of Default, (w) upon the termination of any commitments to extend credit under the Credit Agreement, (x) upon the acceleration of any Indebtedness arising under the Credit Agreement, (y) at the option of Agent or (z) upon the request of the Majority Lenders after the commencement of any remedies hereunder, 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 the Agent, properly endorsed, where required, so that such items may be collected by the 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 the Agent until delivery is made to the Agent. All items or amounts which are remitted to a Lock Box or otherwise delivered by or for the benefit of a Debtor to the Agent on account of partial or full payment of, or any other amount payable with respect to, any of the Collateral shall, at the 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 the Agent a first security interest in and Lien on all funds on deposit in such account. Each Debtor hereby irrevocably authorizes and directs the 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.

21

For purposes of this Agreement “environmental condition” includes, without limitation, conditions existing with respect to the surface or ground water, drinking water supply, land surface or subsurface strata and the ambient air.

Section 7.13 Release of Collateral. The Agent shall, upon the written request of the Debtors, execute and deliver to the Debtors a proper instrument or instruments acknowledging the release of the security interest and Liens established hereby on any Collateral (other than the Pledged Shares): (a) if the sale or other disposition of

23

such Collateral is permitted under the terms of the Credit Agreement and, at the time of such proposed release, both before and after giving effect thereto, no Default or Event of Default has occurred and is continuing, (b) if the sale or other disposition of such Collateral is not permitted under the terms of the Credit Agreement, provided that the requisite Lenders under the Credit Agreement shall have consented to such sale or disposition in accordance with the terms thereof, or (c) if such release has been approved by the requisite Lenders in accordance with Section 13.9 of the Credit Agreement.

Section 7.14 WAIVER OF JURY TRIAL. EACH DEBTOR AND THE AGENT ACKNOWLEDGE THAT THE RIGHT TO TRIAL BY JURY IS A CONSTITUTIONAL ONE, BUT THAT IT MAY BE WAIVED UNDER CERTAIN CIRCUMSTANCES. TO THE EXTENT PERMITTED BY LAW, EACH DEBTOR AND THE AGENT, AFTER CONSULTING (OR HAVING HAD THE OPPORTUNITY TO CONSULT) WITH COUNSEL OF ITS CHOICE, KNOWINGLY AND VOLUNTARILY, AND FOR THE MUTUAL BENEFIT OF ALL PARTIES, WAIVES ANY RIGHT TO TRIAL BY JURY IN THE EVENT OF LITIGATION ARISING OUT OF OR RELATED TO THIS AGREEMENT OR ANY OTHER DOCUMENT, INSTRUMENT OR AGREEMENT BETWEEN THE DEBTORS AND THE AGENT.

(a) In the event that the jury trial waiver contained in this Section 7.14 is not enforceable, the parties elect to proceed as follows:

(b) With the exception of the items specified in clause (c), below, any controversy, dispute or claim (each, a “Claim”) between the parties arising out of or relating to this Agreement or any other Loan Document will be resolved by a reference proceeding in California in accordance with the provisions of Section 638 et seq. of the California Code of Civil Procedure (“CCP”), or their successor sections, which shall constitute the exclusive remedy for the resolution of any Claim, including whether the Claim is subject to the reference proceeding. Except as otherwise provided in the Agreement, venue for the reference proceeding will be in the state or federal court in the county or district where venue is otherwise appropriate under applicable law (the “Court”).

(c) The matters that shall not be subject to a reference are the following: (i) foreclosure of any security interests in real or personal property, (ii) exercise of self-help remedies (including, without limitation, set-off), (iii) appointment of a receiver and (iv) temporary, provisional or ancillary remedies (including, without limitation, writs of attachment, writs of possession, temporary restraining orders or preliminary injunctions). This Section does not limit the right of any party to exercise or oppose any of the rights and remedies described in clauses (i) and (ii) or to seek or oppose from a court of competent jurisdiction any of the items described in clauses (iii) and (iv). The exercise of, or opposition to, any of those items does not waive the right of any party to a reference pursuant to this Section.

(d) The referee shall be a retired judge or justice selected by mutual written agreement of the parties. If the parties do not agree within ten (10) days of a written request to do so by any party, then, upon request of any party, the referee shall be selected by the Presiding Judge of the Court (or his or her representative). A request for appointment of a referee may be heard on an ex parte or expedited basis, and the parties agree that irreparable harm would result if ex parte relief is not granted. Pursuant to CCP § 170.6, each party shall have one peremptory challenge to the referee selected by the Presiding Judge of the Court (or his or her representative).

(e) The parties agree that time is of the essence in conducting the reference proceedings. Accordingly, the referee shall be requested, subject to change in the time periods specified herein for good cause shown, to (a) set the matter for a status and trial-setting conference within fifteen (15) days after the date of selection of the referee, (b) if practicable, try all issues of law or fact within one hundred twenty (120) days after the date of the conference and (c) report a statement of decision within twenty (20) days after the matter has been submitted for decision.

(f) The referee will have power to expand or limit the amount and duration of discovery. The referee may set or extend discovery deadlines or cutoffs for good cause, including a party’s failure to

24

provide requested discovery for any reason whatsoever. Unless otherwise ordered, no party shall be entitled to “priority” in conducting discovery, depositions may be taken by either party upon seven (7) days written notice, and all other discovery shall be responded to within fifteen (15) days after service. All disputes relating to discovery which cannot be resolved by the parties shall be submitted to the referee whose decision shall be final and binding.

(g) Except as expressly set forth in this Section, the referee shall determine the manner in which the reference proceeding is conducted including the time and place of hearings, the order of presentation of evidence, and all other questions that arise with respect to the course of the reference proceeding. All proceedings and hearings conducted before the referee, except for trial, shall be conducted without a court reporter, except that when any party so requests, a court reporter will be used at any hearing conducted before the referee, and the referee will be provided a courtesy copy of the transcript. The party making such a request shall have the obligation to arrange for and pay the court reporter. Subject to the referee’s power to award costs to the prevailing party, the parties will equally share the cost of the referee and the court reporter at trial.

(h) The referee shall be required to determine all issues in accordance with existing case law and the statutory laws of the State of California. The rules of evidence applicable to proceedings at law in the State of California will be applicable to the reference proceeding. The referee shall be empowered to enter equitable as well as legal relief, enter equitable orders that will be binding on the parties and rule on any motion which would be authorized in a trial, including without limitation motions for summary judgment or summary adjudication. The referee shall issue a decision at the close of the reference proceeding which disposes of all claims of the parties that are the subject of the reference. Pursuant to CCP § 644, such decision shall be entered by the Court as a judgment or an order in the same manner as if the action had been tried by the Court and any such decision will be final, binding and conclusive. The parties reserve the right to appeal from the final judgment or order or from any appealable decision or order entered by the referee. The parties reserve the right to findings of fact, conclusions of laws, a written statement of decision, and the right to move for a new trial or a different judgment, which new trial, if granted, is also to be a reference proceeding under this provision.

(i) If the enabling legislation which provides for appointment of a referee is repealed (and no successor statute is enacted), any dispute between the parties that would otherwise be determined by reference procedure will be resolved and determined by arbitration. The arbitration will be conducted by a retired judge or Justice, in accordance with the California Arbitration Act § 1280 through § 1294.2 of the CCP as amended from time to time. The limitations with respect to discovery set forth above shall apply to any such arbitration proceeding.

THE PARTIES RECOGNIZE AND AGREE THAT ALL DISPUTES RESOLVED UNDER THIS REFERENCE PROVISION WILL BE DECIDED BY A REFEREE AND NOT BY A JURY. AFTER CONSULTING (OR HAVING HAD THE OPPORTUNITY TO CONSULT) WITH COUNSEL OF THEIR OWN CHOICE, EACH PARTY KNOWINGLY AND VOLUNTARILY, AND FOR THE MUTUAL BENEFIT OF ALL PARTIES, AGREES THAT THIS REFERENCE PROVISION WILL APPLY TO ANY CONTROVERSY, DISPUTE OR CLAIM BETWEEN OR AMONG THEM WHICH ARISES OUT OF OR IS RELATED TO THE AGREEMENT.

Section 7.15 Consistent Application. The rights and duties created by this Agreement shall, in all cases, be interpreted consistently with, and shall be in addition to (and not in lieu of), the rights and duties created by the Credit Agreement or the other Loan Documents. In the event that any provision of this Agreement shall be inconsistent with any provision of the Credit Agreement, such provision of the Credit Agreement shall govern.

Section 7.16 Continuing Lien. The security interest granted under this Security Agreement shall be a continuing security interest in every respect (whether or not the outstanding balance of the Indebtedness is from time to time temporarily reduced to zero) and the Agent’s security interest in the Collateral as granted herein shall continue in full force and effect for the entire duration that the Credit Agreement remains in effect and until all of the Indebtedness are repaid and discharged in full, and no commitment (whether optional or obligatory) to extend any credit under the Credit Agreement remain outstanding.

25

Section 7.17 Amendment and Restatement. This Agreement amends, restates and replaces in its entirety the security agreement included in the Prior Credit Agreement (the “Prior Security Agreement”), and nothing contained herein shall be deemed to alter or impair the liens and security interest established by the Prior Security Agreement, which liens and security interest remain in full force and effect with all priorities unchanged.
