case without further consent of Borrower or such nominee The provisions of this paragraph shall not apply to any financial assets credited to a securities account for which Lender is the securities intermediary.

4.05 Electronic Chattel Paper and Transferable Records. If Borrower at any time holds or acquires an interest in any electronic chattel paper or any “transferable record,” as that term is defined in Section 201 of the Federal Electronic Signatures in Global and National Commerce Act, or in Section 16 of the Uniform Electronic Transactions Act as in effect in any relevant jurisdiction, Borrower will promptly notify Lender thereof and, at the request of Lender, will take such action as Lender may reasonably request to vest control in Lender, under Section 9-105 of the Uniform Commercial Code, of such electronic chattel paper or control under Section 201 of the Federal Electronic Signatures in Global and National Commerce Act or, as the case may be, Section 16 of the Uniform Electronic Transactions Act, as so in effect in such jurisdiction, of such transferable record.

4.08 Other Actions as to any and all Collateral. Borrower further agrees to take any other action reasonably requested by Lender to insure the attachment, perfection

4

10. Insurance.

10.01 Maintenance of Insurance. Borrower will maintain with financially sound and reputable insurers insurance with respect to its properties and business against such casualties and contingencies as shall be in accordance with general practices of businesses engaged in similar activities in similar geographic areas. Such insurance shall be in such minimum amounts that Borrower will not be deemed a co-insurer under applicable insurance laws, regulations and policies and otherwise shall be in such

6

amounts, contain such terms, be in such forms and be for such periods as may be reasonably satisfactory to Lender. In addition, all such insurance shall be payable to Lender as loss payee under a standard loss payee clause. Without limiting the foregoing, Borrower will (i) keep all of its physical property insured with casualty or physical hazard insurance on an “all risks” basis, with electronic data processing coverage, with a full replacement cost endorsement and in an amount equal to 100% of the full replacement cost of such property, (ii) maintain all such workers’ compensation or similar insurance as may be required by law and (iii) maintain, in amounts and with deductibles equal to those generally maintained by businesses engaged in similar activities in similar geographic areas, general public liability insurance against claims of bodily injury, death or property damage occurring, on, in or about the properties of Borrower; business interruption insurance; and product liability insurance.

10.02 Insurance Proceeds. The proceeds of any casualty insurance in respect of any casualty loss of any of the Collateral shall, subject to the rights, if any, of other parties with a prior interest in the property covered thereby, (i) so long as no Default or Event of Default has occurred and is continuing and to the extent that the amount of such proceeds is less than $1,000,000, be disbursed to Borrower for direct application by Borrower solely to the repair or replacement of Borrower’s property so damaged or destroyed and (ii) in all other circumstances, be held by Lender as cash collateral for the Obligations. Lender may, at its sole option, disburse from time to time all or any part of such proceeds so held as cash collateral, upon such terms and conditions as Lender may reasonably prescribe, for direct application by Borrower solely to the repair or replacement of Borrower’s property so damaged or destroyed, or Lender may apply all or any part of such proceeds to the Obligations with the Commitments (if not then terminated) being reduced by the amount so applied to the Obligations.

10.03 Notice of Cancellation, etc. All policies of insurance will provide for at least 30 days prior written cancellation notice to Lender. In the event of failure by Borrower to provide and maintain insurance as herein provided, Lender may, at its option, provide such insurance and charge the amount thereof to Borrower. Borrower will furnish Lender with certificates of insurance and copies policies evidencing compliance with the foregoing insurance provision.

11. Collateral Protection Expenses; Preservation of Collateral.

11.01 Expenses Incurred by Lender. In its discretion, Lender may discharge taxes and other encumbrances at any time levied or placed on any of the Collateral, make repairs thereto and pay any necessary filing fees or, if the debtor fails to do so, insurance premiums. Borrower agrees to reimburse Lender on demand for any and all expenditures so made. Lender has no obligation to Borrower to make any such expenditures, and the making thereof will not relieve Borrower of any default.

11.02 Lender’s Obligations and Duties. Anything herein to the contrary notwithstanding, Borrower will remain liable under each contract or agreement comprised in the Collateral to be observed or performed by Borrower thereunder. Lender shall not have any obligation or liability under any such contract or agreement by reason

7

of or arising out of this Agreement or the receipt by Lender of any payment relating to any of the Collateral, nor shall Lender be obligated in any manner to perform any of the obligations of Borrower under or pursuant to any such contract or agreement, to make inquiry as to the nature or sufficiency of any payment received by Lender in respect of the Collateral or as to the sufficiency of any performance by any party under any such contract or agreement, to present or file any claim, to take any action to enforce any performance or to collect the payment of any amounts which may have been assigned to Lender or to which Lender may be entitled at any time or times. Lender’s sole duty with respect to the custody, safe keeping and physical preservation of the Collateral in its possession, under Section 9-207 of the Uniform Commercial Code of the State or otherwise, is to deal with such Collateral in the same manner as Lender deals with similar property for its own account.

12. Securities and Deposits. Lender may at any time at its option, transfer to itself or any nominee, for Collateral purposes, any securities constituting Collateral, receive any income thereon and if an Event of Default has occurred and is continuing, hold such income as additional Collateral or apply it to the Obligations. Whether or not any Obligations are due, Lender may demand, sue for, collect, or make any settlement or compromise which it deems desirable with respect to the Collateral. Regardless of the adequacy of Collateral or any other security for the Obligations, any deposits or other sums at any time credited by or due from Lender to Borrower may at any time be applied to or set off against any of the Obligations then due and owing.

13. Notification to Account Debtors and Other Persons Obligated on Collateral. If an Event of Default has occurred and is continuing, Borrower will, at the request of Lender, notify account debtors and other persons obligated on any of the Collateral of the security interest of Lender in any account, chattel paper, general intangible, instrument or other Collateral and that payment thereof is to be made directly to Lender or to any financial institution designated by Lender as Lender’s agent therefor, and Lender may itself, if an Event of Default has occurred and is continuing, without notice to or demand upon Borrower, so notify account debtors and other persons obligated on Collateral. After the making of such a request or the giving of any such notification, Borrower will hold any proceeds of collection of accounts, chattel paper, general intangibles, instruments and other Collateral received by Borrower as trustee for Lender without commingling the same with other funds of Borrower and will turn the same over to Lender in the identical form received, together with any necessary endorsements or assignments. Lender will apply the proceeds of collection of accounts, chattel paper, general intangibles, instruments and other Collateral received by Lender to the Obligations, such proceeds to be immediately entered after final payment in cash or other immediately available funds of the items giving rise to them.

14. Power of Attorney.

14.01 Appointment and Powers of Lender. Borrower hereby irrevocably constitutes and appoints Lender and any officer or agent thereof, with full power of substitution, as its true and lawful attorneys-in-fact with full irrevocable power and authority in the place and stead of Borrower or in Lender’s own name, for the purpose of carrying out the terms of this Agreement, to take any and all appropriate action and to

8

execute any and all documents and instruments that may be necessary or desirable to accomplish the purposes of this Agreement; provided, however, the Lender will not exercise any of the aforementioned rights unless a Default has occurred and is continuing. Without limiting the generality of the foregoing, hereby gives said attorneys the power and right, on behalf of Borrower, without notice to or assent by Borrower, to do the following:

(a) upon the occurrence and during the continuance of an Event of Default, generally to sell, transfer, pledge, make any agreement with respect to or otherwise deal with any of the Collateral in such manner as is consistent with the Uniform Commercial Code of the State and as fully and completely as though Lender were the absolute owner thereof for all purposes, and to do at Borrower’s expense, at any time, or from time to time, all acts and things which Lender deems necessary to protect, preserve or realize upon the Collateral and Lender’s security interest therein, in order to effect the intent of this Agreement, all as fully and effectively as Borrower might do, including, without limitation, (i) the filing and prosecuting of registration and transfer applications with the appropriate federal or local agencies or authorities with respect to trademarks, copyrights and patentable inventions and processes, (ii) upon written notice to Borrower, the exercise of voting rights with respect to voting securities, which rights may be exercised, if Lender so elects, with a view to causing the liquidation in a commercially reasonable manner of assets of the issuer of any such securities and (iii) the execution, delivery and recording, in connection with any sale or other disposition of any Collateral, of the endorsements, assignments or other instruments of conveyance or transfer with respect to such Collateral; and

(b) to the extent that Borrower’s authorization given in Section 3 is not sufficient, to file such financing statements with respect hereto, with or without Borrower’s signature, or a photocopy of this Agreement in substitution for a financing statement, as Lender may deem appropriate and to execute and/or file in Borrower’s name such financing statements and amendments thereto and continuation statements which may require Borrower’s signature.

14.02 Ratification by Borrower. To the extent permitted by law, Borrower hereby ratifies all that said attorneys lawfully do or cause to be done by virtue of this Agreement. This power of attorney is a power coupled with an interest and is irrevocable.

14.03 No Duty on Lender. The powers conferred on Lender hereunder are solely to protect its interests in the Collateral and do not impose any duty upon it to exercise any such powers. Lender will be accountable only for the amounts that it actually receives as a result of the exercise of such powers and neither it nor any of its officers, directors, employees or agents shall be responsible to Borrower for any act or failure to act, except for Lender’s own gross negligence or willful misconduct.

15. Remedies. If an Event of Default has occurred and is continuing, Lender may, without notice to or demand upon Borrower, declare this Agreement to be in default, and Lender shall thereafter have in any jurisdiction in which enforcement hereof is sought, in addition to all

9

other rights and remedies, the rights and remedies of a secured party under the Uniform Commercial Code of the State or of any jurisdiction in which Collateral is located, including, without limitation, the right to take possession of the Collateral, and for that purpose Lender may, so far as Borrower can give authority therefor, enter upon any premises on which the Collateral may be situated and remove the same therefrom. Lender may in its discretion require Borrower to assemble all or any part of the Collateral at such location or locations within the jurisdictions of Borrower’s principal office(s) or at such other locations as Lender may reasonably designate. Unless the Collateral is perishable or threatens to decline speedily in value or is of a type customarily sold on a recognized market, Lender will give to Borrower at least 10 Business Days prior written notice of the time and place of any public sale of Collateral or of the time after which any private sale or any other intended disposition is to be made. Borrower hereby acknowledges that 10 Business Days prior written notice of such sale or sales is reasonable notice. In addition, Borrower waives any and all rights that it may have to a judicial hearing in advance of the enforcement of any of Lender’s rights hereunder, including, without limitation, its right following an Event of Default to take immediate possession of the Collateral and to exercise its rights with respect thereto.

16. Standards for Exercising Remedies. To the extent that applicable law imposes duties on Lender to exercise remedies in a commercially reasonable manner, Borrower acknowledges and agrees that it is not commercially unreasonable for Lender (a) to fail to incur expenses reasonably deemed significant by Lender to prepare Collateral for disposition or otherwise to complete raw material or work in process into finished goods or other finished products for disposition, (b) to fail to obtain third party consents for access to Collateral to be disposed of, or to obtain or, if not required by other law, to fail to obtain governmental or third party consents for the collection or disposition of Collateral to be collected or disposed of, (c) to fail to exercise collection remedies against account debtors or other persons obligated on Collateral or to remove liens or encumbrances on or any adverse claims against Collateral, (d) to exercise collection remedies against account debtors and other persons obligated on Collateral directly or through the use of collection agencies and other collection specialists, (e) to advertise dispositions of Collateral through publications or media of general circulation, whether or not the Collateral is of a specialized nature, (f) to contact other persons, whether or not in the same business as Borrower, for expressions of interest in acquiring all or any portion of the Collateral, (g) to hire one or more professional auctioneers to assist in the disposition of Collateral, whether or not the collateral is of a specialized nature, (h) to dispose of Collateral by utilizing internet sites that provide for the auction of assets of the types included in the Collateral or that have the reasonable capability of doing so, or that match buyers and sellers of assets, (i) to dispose of assets in wholesale rather than retail markets, (j) to disclaim disposition warranties, (k) to purchase insurance or credit enhancements to insure Lender against risks of loss, collection or disposition of Collateral or to provide to Lender a guaranteed return from the collection or disposition of Collateral, or (l) to the extent deemed appropriate by Lender, to obtain the services of other brokers, investment bankers, consultants and other professionals to assist Lender in the collection or disposition of any of the Collateral. Borrower acknowledges that the purpose of this Section 16 is to provide non-exhaustive indications of what actions or omissions by Lender would not be commercially unreasonable in Lender’s exercise of remedies against the Collateral and that other actions or omissions by Lender shall not be deemed commercially unreasonable solely on account of not being indicated in this Section 16. Without limitation upon the foregoing, nothing contained in this Section 16 shall be construed to grant any rights to Borrower or to impose any duties on Lender that would not have been granted or imposed by this Agreement or by applicable law in the absence of this Section 16.

10

17. No Waiver by Lender, etc. Lender shall not be deemed to have waived any of its rights upon or under the Obligations or the Collateral unless such waiver shall be in writing and signed by Lender. No delay or omission on the part of Lender in exercising any right shall operate as a waiver of such right or any other right. A waiver on any one occasion will not be construed as a bar to or waiver of any right on any future occasion. All rights and remedies of Lender with respect to the Obligations or the Collateral, whether evidenced hereby or by any other instrument or papers, will be cumulative and may be exercised singularly, alternatively, successively or concurrently at such time or at such times as Lender deems expedient.

18. Suretyship Waivers by Borrower. Borrower waives demand, notice, protest, notice of acceptance of this Agreement, notice of loans made, credit extended, Collateral received or delivered or other action taken in reliance hereon and all other demands and notices of any description. With respect to both the Obligations and the Collateral, Borrower assents to any extension or postponement of the time of payment or any other indulgence, to any substitution, exchange or release of or failure to perfect any security interest in any Collateral, to the addition or release of any party or person primarily or secondarily liable, to the acceptance of partial payment thereon and the settlement, compromising or adjusting of any thereof, all in such manner and at such time or times as Lender may deem advisable. Lender will have no duty as to the collection or protection of the Collateral or any income thereon, nor as to the preservation of rights against prior parties, nor as to the preservation of any rights pertaining thereto beyond the safe custody thereof as set forth in Section 11.02. Borrower further waives any and all other suretyship defenses.

19. Marshaling. Lender will not be required to marshal any present or future collateral security (including but not limited to this Agreement and the Collateral) for, or other assurances of payment of, the Obligations or any of them or to resort to such collateral security or other assurances of payment in any particular order, and all of its rights hereunder and in respect of such collateral security and other assurances of payment are cumulative and in addition to all other rights, however existing or arising. To the extent that it lawfully may, Borrower hereby agrees that it will not invoke any law relating to the marshalling of collateral which might cause delay in or impede the enforcement of Lender’s rights under this Agreement or under any other instrument creating or evidencing any of the Obligations or under which any of the Obligations is outstanding or by which any of the Obligations is secured or payment thereof is otherwise assured, and, to the extent that it lawfully may, Borrower hereby irrevocably waives the benefits of all such laws.
