After receipt by the Company of a notice from the Collateral Agent that the Collateral Agent has notified, intends to notify, or has enforced or intends to enforce the Company’s rights against the account debtors or obligors under any Accounts as referred to in the proviso to the immediately preceding sentence, (A) all amounts and proceeds (including Instruments) received by the Company in respect of the Accounts shall be received in trust for the benefit of the Collateral Agent hereunder, shall be segregated from other funds of the Company and shall be forthwith paid over to the Collateral Agent in the same form as so received (with any necessary endorsement) to be applied as specified in Section 7(b) hereof, and (B) the Company will not adjust, settle or compromise the amount or payment of any Account or release wholly or partly any account debtor or obligor thereof or allow any credit or discount thereon. In addition, upon the occurrence and during the continuance of an Event of Default, the Collateral Agent may (in its sole and absolute discretion) direct any or all of the banks and financial institutions with which the Company either maintains a Deposit Account or a lockbox or deposits the proceeds of any Accounts to send immediately to the Collateral Agent by wire transfer (to such account as the Collateral Agent shall specify, or in such other manner as the Collateral Agent shall direct) all or a portion of such securities, cash, investments and other items held by such institution. Any such securities, cash, investments and other items so received by the Collateral Agent shall be applied as specified in accordance with Section 7(b) hereof.

          (iii) Upon the occurrence and during the continuance of any breach or default under any material License referred to in Schedule II hereto by any party thereto other than the Company, the Company will, promptly after obtaining knowledge thereof, give the Collateral Agent written notice of the nature and duration thereof, specifying what action, if any, it has taken and proposes to take with respect thereto and thereafter will take reasonable steps to protect and preserve its rights and remedies in respect of such breach or default, or will obtain or acquire an appropriate substitute License.

          (iv) The Company will, at its expense, promptly deliver to the Collateral Agent a copy of each notice or other communication received by it by which any other party to any material License referred to in Schedule II hereto purports to exercise any of its

-12-

rights or affect any of its obligations thereunder, together with a copy of any reply by the Company thereto.

          (v) The Company will exercise promptly and diligently each and every right which it may have under each material License (other than any right of termination) and will duly perform and observe in all respects all of its obligations under each material License and will take all action reasonably necessary to maintain such Licenses in full force and effect. The Company will not, without the prior written consent of the Collateral Agent, cancel, terminate, amend or otherwise modify in any respect, or waive any provision of, any material License referred to in Schedule II hereto.

     (g) Transfers and Other Liens.

          (i) The Company will not sell, assign (by operation of law or otherwise), lease, license, exchange or otherwise transfer or dispose of any of the Collateral, except (A) Inventory in the ordinary course of business, and (B) worn out or obsolete assets, not necessary to the business.

          (ii) The Company will not create, suffer to exist or grant any Lien upon or with respect to any Collateral other than a Permitted Lien.

     (h) Intellectual Property.

          (i) If applicable, the Company shall, upon the Collateral Agent’s written request, duly execute and deliver the applicable Assignment for Security in the form attached hereto as Exhibit A. The Company (either itself or through licensees) will, and will cause each licensee thereof to, take all action necessary to maintain all of the Intellectual Property in full force and effect, including, without limitation, using the proper statutory notices and markings and using the Trademarks on each applicable trademark class of goods in order to so maintain the Trademarks in full force and free from any claim of abandonment for non-use, and the Company will not (nor permit any licensee thereof to) do any act or knowingly omit to do any act whereby any Intellectual Property may become invalidated; provided, however, that so long as no Event of Default has occurred and is continuing, the Company shall have no obligation to use or to maintain any Intellectual Property (A) that relates solely to any product or work, that has been, or is in the process of being, discontinued, abandoned or terminated, (B) that is being replaced with Intellectual Property substantially similar to the Intellectual Property that may be abandoned or otherwise become invalid, so long as the failure to use or maintain such Intellectual Property does not materially adversely affect the validity of such replacement Intellectual Property and so long as such replacement Intellectual Property is subject to the Lien created by this Agreement or (C) that is substantially the same as another Intellectual Property that is in full force, so long the failure to use or maintain such Intellectual Property does not materially adversely affect the validity of such replacement Intellectual Property and so long as such other Intellectual Property is subject to the Lien and security interest created by this Agreement. The Company will cause to be taken all necessary steps in any proceeding before the United States Patent and Trademark Office and the United States Copyright Office or any similar office or agency in any other country or political subdivision thereof to maintain each registration of the Intellectual Property (other than the Intellectual Property described in the proviso to the immediately preceding sentence), including,

-13-

without limitation, filing of renewals, affidavits of use, affidavits of incontestability and opposition, interference and cancellation proceedings and payment of maintenance fees, filing fees, taxes or other governmental fees. If any Intellectual Property (other than Intellectual Property described in the proviso to the first sentence of subsection (i) of this clause (h)) is infringed, misappropriated, diluted or otherwise violated in any material respect by a third party, the Company shall (x) upon learning of such infringement, misappropriation, dilution or other violation, promptly notify the Collateral Agent and (y) to the extent the Company shall deem appropriate under the circumstances, promptly sue for infringement, misappropriation, dilution or other violation, seek injunctive relief where appropriate and recover any and all damages for such infringement, misappropriation, dilution or other violation, or take such other actions as the Company shall deem appropriate under the circumstances to protect such Intellectual Property. The Company shall furnish to the Collateral Agent from time to time upon its request statements and schedules further identifying and describing the Intellectual Property and Licenses and such other reports in connection with the Intellectual Property and Licenses as the Collateral Agent may reasonably request, all in reasonable detail and promptly upon request of the Collateral Agent, following receipt by the Collateral Agent of any such statements, schedules or reports, the Company shall modify this Agreement by amending Schedule II hereto, as the case may be, to include any Intellectual Property and License, as the case may be, which becomes part of the Collateral under this Agreement and shall execute and authenticate such documents and do such acts as shall be necessary or, in the reasonable judgment of the Collateral Agent, desirable to subject such Intellectual Property and Licenses to the Lien and security interest created by this Agreement. Notwithstanding anything herein to the contrary, upon the occurrence and during the continuance of an Event of Default, the Company may abandon or otherwise permit any Intellectual Property to become invalid without the prior written consent of the Collateral Agent, and if any Intellectual Property is infringed, misappropriated, diluted or otherwise violated in any material respect by a third party, the Company will take such action as the Collateral Agent shall deem appropriate under the circumstances to protect such Intellectual Property.

          (ii) In no event shall the Company, either itself or through any agent, employee, licensee or designee, file an application for the registration of any Trademark or Copyright or the issuance of any Patent with the United States Patent and Trademark Office or the United States Copyright Office, as applicable, or in any similar office or agency of the United States or any country or any political subdivision thereof unless it gives the Collateral Agent prior written notice thereof. Upon request of the Collateral Agent, the Company shall execute, authenticate and deliver any and all assignments, agreements, instruments, documents and papers as the Collateral Agent may reasonably request to evidence the Collateral Agent’s security interest hereunder in such Intellectual Property and the General Intangibles of the Company relating thereto or represented thereby, and the Company hereby appoints the Collateral Agent its attorney-in-fact to execute and/or authenticate and file all such writings for the foregoing purposes, all acts of such attorney being hereby ratified and confirmed, and such power (being coupled with an interest) shall be irrevocable until the indefeasible payment in full in cash of all of the Obligations in full.

     (i) Deposit, Commodities and Securities Accounts. Upon the Collateral Agent’s written request and subject to Section 10(f) of the Note, the Company shall cause each bank and other financial institution with an account referred to in Schedule IV hereto to execute and deliver to the Collateral Agent a control agreement, in form and substance reasonably

satisfactory to the Collateral Agent, duly executed by the Company and such bank or financial institution, or enter into other arrangements in form and substance satisfactory to the Collateral Agent, pursuant to which such institution shall irrevocably agree, inter alia, that (i) it will comply at any time with the instructions originated by the Collateral Agent to such bank or financial institution directing the disposition of cash, Commodity Contracts, securities, Investment Property and other items from time to time credited to such account, without further consent of the Company, which instructions the Collateral Agent will not give to such bank or other financial institution in the absence of a continuing Event of Default under Sections 3(a)(i), 3(a)(ii), 3(a)(iii) and 3(a)(iv) of the Note, (ii) all Commodity Contracts, securities, Investment Property and other items of the Company deposited with such institution shall be subject to a perfected, first priority security interest in favor of the Collateral Agent, (iii) any right of set off (other than recoupment of standard fees), banker’s Lien or other similar Lien, security interest or encumbrance shall be fully waived as against the Collateral Agent, and (iv) upon receipt of written notice from the Collateral Agent during the continuance of an Event of Default, such bank or financial institution shall immediately send to the Collateral Agent by wire transfer (to such account as the Collateral Agent shall specify, or in such other manner as the Collateral Agent shall direct) all such cash (not to exceed, in any event, the Obligations), the value of any Commodity Contracts, securities, Investment Property and other items held by it. Without the prior written consent of the Collateral Agent, the Company shall not make or maintain any Deposit Account, Commodity Account or Securities Account except for the accounts set forth in Schedule IV hereto. The provisions of this paragraph 5(i) shall not apply to (i) Deposit Accounts for which the Collateral Agent is the depositary and (ii) Deposit Accounts specially and exclusively used for payroll, payroll taxes and other employee wage and benefit payments to or for the benefit of the Company’s salaried or hourly employees.

     (j) Titled Collateral. At the request of the Collateral Agent’s written request, the Company shall (i) cause all Collateral, now owned or hereafter acquired by the Company, which under applicable law are required to be registered, to be properly registered in the name of the Company, (ii) cause all Titled Collateral, to be properly titled in the name of the Company, and if requested by the Collateral Agent, with the Collateral Agent’s Lien noted thereon and (iii) if requested by the Collateral Agent, promptly deliver to the Collateral Agent (or its custodian) originals of such Certificates of Title or certificates of ownership for such Titled Collateral, with the Collateral Agent’s Lien noted thereon, and take such other actions as may be reasonably required by the Collateral Agent.

     (k) Control. The Company hereby agrees to take any or all action that may be necessary or that the Collateral Agent may reasonably request in order for the Collateral Agent to obtain control in accordance with Sections 9-105 – 9-107 of the Code with respect to the following Collateral: (i) Electronic Chattel Paper, (ii) Investment Property, and (iii) Letter-of-Credit Rights.

     (l) Inspection and Reporting. The Company shall permit the Collateral Agent, or any agent or representatives thereof or such professionals or other Persons as the Collateral Agent may designate, during normal business hours, after reasonable notice in the absence of an Event of Default, and charge such costs for one visit per year to the Company therefor, (i) to examine and make copies of and abstracts from the Company’s records and books of account, (ii) to visit and inspect its properties, (iii) to verify materials, leases, Instruments,

The Company shall also permit the Collateral Agent, or any agent or representatives thereof or such professionals or other Persons as the Collateral Agent may designate to discuss the Company’s affairs, finances and accounts with any of its directors, officers, managerial employees, independent accountants or any of its other representatives.

     (m) Future Subsidiaries. Future Subsidiaries. If the Company shall hereafter create or acquire (i) any Subsidiary with assets in excess of $1,000,000, simultaneously with the creation or acquisition of such Subsidiary, or (ii) if any Subsidiary so created or acquired shall subsequently acquire obtain assets such that the total assets of such Subsidiary exceed $1,000,000, then within 5 Business Days, the Company shall (x) execute and deliver to the Collateral Agent, a pledge agreement, in form and substance satisfactory to the Collateral Agent, pursuant to which the Company shall pledge the securities, partnership, membership or other equity interests of such Subsidiary to the Collateral Agent as additional collateral for the payment and performance of the Obligations, together with (A) certificates, if any, evidencing all of the securities, partnership, membership or other equity interests of such Subsidiary, (B) undated stock powers or other appropriate instruments of assignment executed in blank with signature guaranteed, (C) such opinion of counsel and such approving certificate of such Subsidiary as the Collateral Agent may reasonably request in respect of complying with any legend on any such certificate or any other matter relating to such shares and (D) such other agreements, instruments, approvals, legal opinions or other documents requested by the Collateral Agent, (y) cause such Subsidiary to duly execute and deliver a guaranty of the Obligations in favor of the Collateral Agent in form and substance reasonably acceptable to the Collateral Agent, and (z) shall duly execute and/or deliver such opinions of counsel and other documents, in form and substance reasonably acceptable to the Collateral Agent, as the Collateral Agent shall reasonably request with respect thereto, provided that the Company that acquires a subsidiary on or within two days after the Closing Date shall have 10 Business Days in which to satisfy the requirements of this Section 5(m).

     SECTION 6. Additional Provisions Concerning the Collateral.

     (a) To the maximum extent permitted by applicable law, and for the purpose of taking any action that the Collateral Agent may deem necessary or advisable to accomplish the purposes of this Agreement, the Company hereby (i) authorizes the Collateral Agent to execute any such agreements, instruments or other documents in the Company’s name and to file such agreements, instruments or other documents in the Company’s name and in any appropriate filing office, (ii) authorizes the Collateral Agent at any time and from time to time to file, one or more financing or continuation statements, and amendments thereto, relating to the Collateral (including, without limitation, any such financing statements that (A) describe the Collateral as “all assets” or “all personal property” (or words of similar effect) or that describe or identify the Collateral by type or in any other manner as the Collateral Agent may determine regardless of whether any particular asset of the Company falls within the scope of Article 9 of the Uniform Commercial Code or whether any particular asset of the Company constitutes part of the Collateral, and (B) contain any other information required by Part 5 of Article 9 of the Code for the sufficiency or filing office acceptance of any financing statement, continuation statement or amendment, including, without limitation, whether the Company is an organization, the type of

organization and any organizational identification number issued to the Company ) and (iii) ratifies such authorization to the extent that the Collateral Agent has filed any such financing or continuation statements, or amendments thereto, prior to the date hereof. A photocopy or other reproduction of this Agreement or any financing statement covering the Collateral or any part thereof shall be sufficient as a financing statement where permitted by law.

     (b) The Company hereby irrevocably appoints the Collateral Agent as its attorney-in-fact and proxy, with full authority in the place and stead of the Company and in the name of the Company or otherwise, from time to time in the Collateral Agent’s discretion, so long as an Event of Default shall have occurred and is continuing, to take any action and to execute any instrument which the Collateral Agent may reasonably deem necessary or advisable to accomplish the purposes of this Agreement (subject to the rights of the Company under Section 5 hereof), including, without limitation, (i) to obtain and adjust insurance required to be paid to the Collateral Agent pursuant to Section 5(e) hereof, (ii) to ask, demand, collect, sue for, recover, compound, receive and give acquittance and receipts for moneys due and to become due under or in respect of any Collateral, (iii) to receive, endorse, and collect any drafts or other instruments, documents and chattel paper in connection with clause (i) or (ii) above, (iv) to file any claims or take any action or institute any proceedings which the Collateral Agent may deem necessary or desirable for the collection of any Collateral or otherwise to enforce the rights of the Collateral Agent and the Buyers with respect to any Collateral, and (v) to execute assignments, licenses and other documents to enforce the rights of the Collateral Agent and the Buyers with respect to any Collateral. This power is coupled with an interest and is irrevocable until all of the Obligations are indefeasibly paid in full in cash.

     (c) For the purpose of enabling the Collateral Agent to exercise rights and remedies hereunder, at such time as the Collateral Agent shall be lawfully entitled to exercise such rights and remedies, and for no other purpose, the Company hereby grants to the Collateral Agent, to the extent assignable, an irrevocable, non-exclusive license (exercisable without payment of royalty or other compensation to the Company) to use, assign, license or sublicense any Intellectual Property now owned or hereafter acquired by the Company, wherever the same may be located, including in such license reasonable access to all media in which any of the licensed items may be recorded or stored and to all computer programs used for the compilation or printout thereof. Notwithstanding anything contained herein to the contrary, but subject to the provisions of the Securities Purchase Agreement that limit the right of the Company to dispose of its property, and Section 5(g) and Section 5(h) hereof, so long as no Event of Default shall have occurred and be continuing, the Company may exploit, use, enjoy, protect, license, sublicense, assign, sell, dispose of or take other actions with respect to the Intellectual Property in the ordinary course of its business. In furtherance of the foregoing, unless an Event of Default shall have occurred and be continuing, the Collateral Agent shall from time to time, upon the request of the Company, execute and deliver any instruments, certificates or other documents, in the form so requested, which the Company shall have certified are appropriate (in the Company’s judgment) to allow it to take any action permitted above (including relinquishment of the license provided pursuant to this clause (c) as to any Intellectual Property). Further, upon the indefeasible payment in full in cash of all of the Obligations, the Collateral Agent (subject to Section 10(e) hereof) shall release and reassign to the Company all of the Collateral Agent’s right, title and interest in and to the Intellectual Property, and the Licenses, all without recourse, representation or warranty whatsoever. The exercise of rights and remedies hereunder by the

Collateral Agent shall not terminate the rights of the holders of any licenses or sublicenses theretofore granted by the Company in accordance with the second sentence of this clause (c). The Company hereby releases the Collateral Agent from any claims, causes of action and demands at any time arising out of or with respect to any actions taken or omitted to be taken by the Collateral Agent under the powers of attorney granted herein other than actions taken or omitted to be taken through the Collateral Agent’s gross negligence or willful misconduct, as determined by a final determination of a court of competent jurisdiction.

     (d) If the Company fails to perform any agreement or obligation contained herein, the Collateral Agent may itself perform, or cause performance of, such agreement or obligation, in the name of the Company or the Collateral Agent, and the expenses of the Collateral Agent incurred in connection therewith shall be payable by the Company pursuant to Section 8 hereof and shall be secured by the Collateral.

     (e) The powers conferred on the Collateral Agent hereunder are solely to protect its interest in the Collateral and shall not impose any duty upon it to exercise any such powers. Except for the safe custody of any Collateral in its possession and the accounting for moneys actually received by it hereunder, the Collateral Agent shall have no duty as to any Collateral or as to the taking of any necessary steps to preserve rights against prior parties or any other rights pertaining to any Collateral.

     (f) Anything herein to the contrary notwithstanding (i) the Company shall remain liable under the Licenses and otherwise with respect to any of the Collateral to the extent set forth therein to perform all of its obligations thereunder to the same extent as if this Agreement had not been executed, (ii) the exercise by the Collateral Agent of any of its rights hereunder shall not release the Company from any of its obligations under the Licenses or otherwise in respect of the Collateral, and (iii) the Collateral Agent shall not have any obligation or liability by reason of this Agreement under the Licenses or with respect to any of the other Collateral, nor shall the Collateral Agent be obligated to perform any of the obligations or duties of the Company thereunder or to take any action to collect or enforce any claim for payment assigned hereunder.

     SECTION 7. Remedies Upon Event of Default. If any Event of Default shall have occurred and be continuing:

     (a) The Collateral Agent may exercise in respect of the Collateral, in addition to any other rights and remedies provided for herein or otherwise available to it, all of the rights and remedies of a secured party upon default under the Code (whether or not the Code applies to the affected Collateral), and also may (i) take absolute control of the Collateral, including, without limitation, transfer into the Collateral Agent’s name or into the name of its nominee or nominees (to the extent the Collateral Agent has not theretofore done so) and thereafter receive, for the benefit of the Collateral Agent, all payments made thereon, give all consents, waivers and ratifications in respect thereof and otherwise act with respect thereto as though it were the outright owner thereof, (ii) require the Company to, and the Company hereby agrees that it will at its expense and upon request of the Collateral Agent forthwith, assemble all or part of its respective Collateral as directed by the Collateral Agent and make it available to the Collateral Agent at a place or places to be designated by the Collateral Agent that is reasonably convenient

to both parties, and the Collateral Agent may enter into and occupy any premises owned or leased by the Company where the Collateral or any part thereof is located or assembled for a reasonable period in order to effectuate the Collateral Agent’s rights and remedies hereunder or under law, without obligation to the Company in respect of such occupation, and (iii) without notice except as specified below and without any obligation to prepare or process the Collateral for sale, (A) sell the Collateral or any part thereof in one or more parcels at public or private sale, at any of the Collateral Agent’s offices or elsewhere, for cash, on credit or for future delivery, and at such price or prices and upon such other terms as the Collateral Agent may deem commercially reasonable and/or (B) lease, license or dispose of the Collateral or any part thereof upon such terms as the Collateral Agent may deem commercially reasonable. The Company agrees that, to the extent notice of sale or any other disposition of its respective Collateral shall be required by law, at least ten (10) days’ notice to the Company of the time and place of any public sale or the time after which any private sale or other disposition of its respective Collateral is to be made shall constitute reasonable notification. The Collateral Agent shall not be obligated to make any sale or other disposition of any Collateral regardless of notice of sale having been given. The Collateral Agent may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned. The Company hereby waives any claims against the Collateral Agent and the Buyers arising by reason of the fact that the price at which its respective Collateral may have been sold at a private sale was less than the price which might have been obtained at a public sale or was less than the aggregate amount of the Obligations, even if the Collateral Agent accepts the first offer received and does not offer such Collateral to more than one offeree, and waives all rights that the Company may have to require that all or any part of such Collateral be marshaled upon any sale (public or private) thereof. The Company hereby acknowledges that (i) any such sale of its respective Collateral by the Collateral Agent shall be made without warranty, (ii) the Collateral Agent may specifically disclaim any warranties of title, possession, quiet enjoyment or the like, and (iii) such actions set forth in clauses (i) and (ii) above shall not adversely affect the commercial reasonableness of any such sale of Collateral. In addition to the foregoing, (1) upon written notice to the Company from the Collateral Agent after and during the continuance of an Event of Default, the Company shall cease any use of the Intellectual Property or any trademark, patent or copyright similar thereto for any purpose described in such notice; (2) the Collateral Agent may, at any time and from time to time after and during the continuance of an Event of Default, upon 10 days’ prior notice to the Company, license, whether general, special or otherwise, and whether on an exclusive or non-exclusive basis, any of the Intellectual Property, throughout the universe for such term or terms, on such conditions, and in such manner, as the Collateral Agent shall in its sole discretion determine; and (3) the Collateral Agent may, at any time, pursuant to the authority granted in Section 6 hereof (such authority being effective upon the occurrence and during the continuance of an Event of Default), execute and deliver on behalf of the Company, one or more instruments of assignment of the Intellectual Property (or any application or registration thereof), in form suitable for filing, recording or registration in any country.

     (b) Any cash held by the Collateral Agent as Collateral and all Cash Proceeds received by the Collateral Agent in respect of any sale of or collection from, or other realization upon, all or any part of the Collateral shall be applied (after payment of any amounts payable to the Collateral Agent pursuant to Section 8 hereof) by the Collateral Agent against, all or any part of the Obligations in such order as the Collateral Agent shall elect, consistent with the provisions

of the Securities Purchase Agreement. Any surplus of such cash or Cash Proceeds held by the Collateral Agent and remaining after the indefeasible payment in full in cash of all of the Obligations shall be paid over to whomsoever shall be lawfully entitled to receive the same or as a court of competent jurisdiction shall direct.

     (c) In the event that the proceeds of any such sale, collection or realization are insufficient to pay all amounts to which the Collateral Agent and the Buyers are legally entitled, the Company shall be liable for the deficiency, together with interest thereon at the highest rate specified in the Notes for interest on overdue principal thereof or such other rate as shall be fixed by applicable law, together with the costs of collection and the reasonable fees, costs, expenses and other client charges of any attorneys employed by the Collateral Agent to collect such deficiency.

     (d) The Company hereby acknowledges that if the Collateral Agent complies with any applicable state, provincial, or federal law requirements in connection with a disposition of the Collateral, such compliance will not adversely affect the commercial reasonableness of any sale or other disposition of the Collateral.

     (e) The Collateral Agent shall 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 the Collateral Agent’s rights hereunder and in respect of such collateral security and other assurances of payment shall be cumulative and in addition to all other rights, however existing or arising. To the extent that the Company lawfully may, the Company hereby agrees that it will not invoke any law relating to the marshaling of collateral which might cause delay in or impede the enforcement of the Collateral Agent’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, the Company hereby irrevocably waives the benefits of all such laws.

     SECTION 8. Indemnity and Expenses.

     (a) The Company agrees to defend, protect, indemnify and hold the Collateral Agent and each of the Buyers, jointly and severally, harmless from and against any and all claims, damages, losses, liabilities, obligations, penalties, fees, costs and expenses (including, without limitation, reasonable legal fees, costs, expenses, and disbursements of such Person’s counsel) to the extent that they arise out of or otherwise result from this Agreement (including, without limitation, enforcement of this Agreement), except to the extent resulting from such Person’s gross negligence or willful misconduct, as determined by a final judgment of a court of competent jurisdiction.

     (b) The Company agrees to pay to the Collateral Agent upon demand the amount of any and all costs and expenses, including the reasonable fees, costs, expenses and disbursements of counsel for the Collateral Agent and of any experts and agents (including, without limitation, any collateral trustee which may act as agent of the Collateral Agent), which the Collateral Agent may incur in connection with (i) the preparation, negotiation, execution,

delivery, recordation, administration, amendment, waiver or other modification or termination of this Agreement, (ii) the custody, preservation, use or operation of, or the sale of, collection from, or other realization upon, any Collateral, (iii) the exercise or enforcement of any of the rights of the Collateral Agent hereunder, or (iv) the failure by the Company to perform or observe any of the provisions hereof.

     SECTION 9. Notices, Etc. All notices and other communications provided for hereunder shall be in writing and shall be mailed (by certified mail, postage prepaid and return receipt requested), telecopied, e-mailed or delivered if to the Company at its address below and if to the Collateral Agent to it, at its address specified on the signature pages below; or as to any such Person, at such other address as shall be designated by such Person in a written notice to all other parties hereto complying as to delivery with the terms of this Section 9. All such notices and other communications shall be effective (a) if sent by certified mail, return receipt requested, when received or three days after deposited in the mails, whichever occurs first, (b) if telecopied or e-mailed, when transmitted (during normal business hours) and confirmation is received, and otherwise, the day after the notice or communication was transmitted and confirmation is received, or (c) if delivered in person, upon delivery.

SECTION 10. Miscellaneous.

     (a) No amendment of any provision of this Agreement shall be effective unless it is in writing and signed by the Company and the Collateral Agent, and no waiver of any provision of this Agreement, and no consent to any departure by the Company therefrom, shall be effective unless it is in writing and signed by the Company and the Collateral Agent, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given.

     (b) No failure on the part of the Collateral Agent to exercise, and no delay in exercising, any right hereunder or under any of the other Transaction Documents shall operate as a waiver thereof; nor shall any single or partial exercise of any such right preclude any other or further exercise thereof or the exercise of any other right. The rights and remedies of the Collateral Agent or any Buyer provided herein and in the other Transaction Documents are cumulative and are in addition to, and not exclusive of, any rights or remedies provided by law. The rights of the Collateral Agent or any Buyer under any of the other Transaction Documents against any party thereto are not conditional or contingent on any attempt by such Person to exercise any of its rights under any of the other Transaction Documents against such party or against any other Person, including but not limited to, the Company.

     (c) Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining portions hereof or thereof or affecting the validity or enforceability of such provision in any other jurisdiction.

     (d) This Agreement shall create a continuing security interest in the Collateral and shall (i) remain in full force and effect until the indefeasible payment in full in cash of the Obligations, and (ii) be binding on the Company and all other Persons who become bound as debtor to this Agreement in accordance with Section 9-203(d) of the Code and shall inure,

together with all rights and remedies of the Collateral Agent and the Buyers hereunder, to the benefit of the Collateral Agent and the Buyers and their respective permitted successors, transferees and assigns. Without limiting the generality of clause (ii) of the immediately preceding sentence, without notice to the Company, the Collateral Agent and the Buyers may assign or otherwise transfer their rights and obligations under this Agreement and any of the other Transaction Documents, to any other Person and such other Person shall thereupon become vested with all of the benefits in respect thereof granted to the Collateral Agent and the Buyers herein or otherwise. Upon any such assignment or transfer, all references in this Agreement to the Collateral Agent or any such Buyer shall mean the assignee of the Collateral Agent or such Buyer. None of the rights or obligations of the Company hereunder may be assigned or otherwise transferred without the prior written consent of the Collateral Agent, and any such assignment or transfer without the consent of the Collateral Agent shall be null and void.
