Each Grantor will, if so requested by the Agent, deliver to the Agent original or duplicate policies or certificates of such insurance provided by the insurance companies and, as often as the Agent may reasonably request, a report of a reputable insurance broker with respect to such insurance. Further, each Grantor will, at the request of the Agent, duly execute and deliver instruments of assignment of such insurance policies to comply with the requirements of this Section 8 and use reasonable efforts to cause the insurers to acknowledge notice of such assignment.

(b) Reimbursement under any liability insurance maintained by any Grantor pursuant to this Section 8 may be paid directly to the Person who shall have incurred liability covered by such insurance. In case of any loss involving damage to Equipment or Inventory when subsection (c) of this Section 8 is not applicable, the applicable Grantor will make or cause to be made the necessary repairs to or replacements of such Equipment or Inventory, and any proceeds of insurance properly received by or released to such Grantor shall be used by such Grantor, except as otherwise required hereunder or by the Securities Purchase Agreement, to pay or as reimbursement for the costs of such repairs or replacements.

(c) So long as no Event of Default shall have occurred and be continuing, all insurance payments received by the Agent in connection with any loss, damage or destruction of any Inventory or Equipment will be released by the Agent to the applicable Grantor for the repair, replacement or restoration thereof, subject to such terms and conditions with respect to the release thereof as the Agent may reasonably require. To the extent that (i) the amount of any such insurance payments exceeds the cost of any such repair, replacement or restoration, or (ii) such insurance payments are not otherwise required by the applicable Grantor to complete any such repair, replacement or restoration required hereunder, the Agent will not be required to release the amount thereof to such Grantor and may hold or continue to hold such amount as additional security for the Secured Obligations of such Grantor (except that the Agent will release to such Grantor any such amount if and to the extent that any prepayment of the Notes is required under the Securities Purchase Agreement in connection with the receipt of such amount and such prepayment has been made). Upon the occurrence and during the continuance of any Event of Default, all insurance payments in respect of such Equipment or Inventory shall be paid to the Agent and shall, in the Agent’s sole discretion, (i) be released to the applicable Grantor to be applied as set forth in the first sentence of this subsection (c) or (ii) be held as additional Collateral hereunder or applied as specified in Section 16(b).

SECTION 9. Place of Perfection; Records; Collection of Receivables.

(a) No Grantor will change its name, type of legal entity, federal tax identification number, organizational identification number or location from those set forth in Section 5(a) and Section 5(b) without first giving at least 30 days’ advance written notice to the Agent and taking all action required by the Agent for the purpose of perfecting or protecting the liens granted by this Agreement. Each Grantor will also keep the originals of the Related Contracts to which such Grantor is a party and all originals of all chattel paper that evidence Receivables of such Grantor, at the location therefor specified in Section 5(a) or, upon 30 days’ prior written notice to the Agent, at such other location in a jurisdiction where all actions

required by Section 6 shall have been taken with respect to the Collateral of such Grantor (and, upon the taking of such action in such jurisdiction, Schedule III hereto shall be automatically amended to include such other location). Each Grantor will hold and preserve its records relating to the Collateral, the Related Contracts and chattel paper and will permit representatives of the Agent at any time during normal business hours and with reasonable prior notice to inspect and make abstracts from such records and other documents.

(b) Except as otherwise provided in this subsection (b), each Grantor will continue to collect, at its own expense, all amounts due or to become due to such Grantor under the Receivables and the Related Contracts. In connection with such collections, such Grantor may take (and, at the Agent’s direction upon the occurrence and during the continuance of an Event of Default, will take) such action as such Grantor or the Agent may deem reasonably necessary or advisable to enforce collection of the Receivables and the Related Contracts; provided that the Agent shall have the right at any time, upon the occurrence and during the continuance of an Event of Default, to notify the obligors (each individually, a “Contract Obligor” and collectively, the “Contract Obligors”) under any Receivables or Related Contracts of the assignment of such Receivables or Related Contracts to the Agent and to direct such Contract Obligors to make payment of all amounts due or to become due to such Grantor thereunder directly to the Agent and, upon such notification and at the expense of such Grantor, to enforce collection of any such Receivables or Related Contracts, and to adjust, settle or compromise the amount or payment thereof, in the same manner and to the same extent as such Grantor might have done. Upon the occurrence and during the continuance of an Event of Default, (i) all amounts and proceeds (including instruments) received by such Grantor in respect of the Receivables and the Related Contracts of such Grantor shall be received in trust for the benefit of the Agent hereunder, shall be segregated from other funds of such Grantor and shall be forthwith paid over to the Agent in the same form as so received (with any necessary endorsement) to be held as cash collateral and shall be applied as provided in Section 16(b) and (ii) such Grantor will not adjust, settle or compromise the amount or payment of any Receivable, release wholly or partly any Contract Obligor thereof, or allow any credit or discount thereon. No Grantor will permit or consent to the subordination of its right to payment under any of the Receivables or the Related Contracts to any other indebtedness or obligations of the Contract Obligor thereof.

SECTION 10. As to Intellectual Property Collateral.

(a) With respect to each item of its Intellectual Property Collateral (except with respect to any items of Intellectual Property Collateral which such Grantor, in its reasonable business judgment, deems not to be material to the ongoing business of such Grantor), each Grantor agrees to take, at its expense, all necessary steps, including, without limitation, in the U.S. Patent and Trademark Office, the U.S. Copyright Office and any other governmental authority, to (i) maintain the validity and enforceability of each such item of Intellectual Property Collateral and maintain each such item of Intellectual Property Collateral in full force and effect, and (ii) pursue the registration and maintenance of each patent, trademark, or copyright registration or application, now or hereafter included in the Intellectual Property Collateral of such Grantor, including, without limitation, the payment of required fees and taxes, the filing of responses to office actions issued by the U.S. Patent and Trademark Office, the U.S. Copyright Office or other governmental authorities, the filing of applications for renewal or extension, the

filing of affidavits under Sections 8 and 15 of the U.S. Trademark Act, the filing of divisional, continuation, continuation-in-part, reissue and renewal applications or extensions, the payment of maintenance fees and the participation in interference, reexamination, opposition, cancellation, infringement and misappropriation proceedings. Each Grantor shall give the Agent prompt written notice of any applications or registrations of the Intellectual Property Collateral of such Grantor filed with the U.S. Patent and Trademark Office, including the date of such filing and the registration or application numbers, if any, and each Grantor shall give the Agent not less than 30 days prior written notice of the filing of any applications or registrations of the Intellectual Property Collateral of such Grantor filed with the U.S. Copyright Office, including the title of such Intellectual Property Collateral to be registered, as such title will appear on such applications or registrations, and the date such applications or registrations will be filed. No Grantor shall, without the written consent of the Agent, discontinue use of or otherwise abandon any Intellectual Property Collateral, or abandon any right to file an application for letters patent, trademark, or copyright, unless such Grantor shall have previously determined that such use or the pursuit or maintenance of such Intellectual Property Collateral is no longer desirable in the conduct of such Grantor’s business, in which case, such Grantor will give prompt notice of any such abandonment to the Agent.

(b) Except as provided in this Section regarding the discontinuation of use or abandonment of any Intellectual Property Collateral, each Grantor agrees promptly to notify the Agent if such Grantor learns (i) that any item of the Intellectual Property Collateral may have become abandoned, placed in the public domain, invalid or unenforceable, or of any adverse determination or development regarding such Grantor’s ownership of any of the Intellectual Property Collateral or its right to register the same or to keep and maintain and enforce the same, or (ii) of any adverse determination or the institution of any proceeding (including, without limitation, the institution of any proceeding in the U.S. Patent and Trademark Office or any court) regarding any item of the Intellectual Property Collateral.

(c) In the event that any Grantor becomes aware that any item of the Intellectual Property Collateral material to the business of such Grantor is being infringed or misappropriated by a third party, such Grantor shall promptly notify the Agent and shall take such actions, at its expense, as such Grantor or the Agent deems reasonable and appropriate under the circumstances to protect such Intellectual Property Collateral, including, without limitation, suing for infringement or misappropriation and for an injunction against such infringement or misappropriation.

(d) Each Grantor shall use proper statutory notice in connection with its use of each item of its Intellectual Property Collateral. Except with respect of any item of Intellectual Property Collateral, which such Grantor, in the reasonable exercise of its business judgment, deems not to be material to the ongoing business of such Grantor, no Grantor shall do or permit any act or knowingly omit to do any act whereby any of its Intellectual Property Collateral may lapse or become invalid or unenforceable or placed in the public domain.

(e) Except with respect to any item of Intellectual Property Collateral, which such Grantor, in the reasonable exercise of its business judgment, deems not to be material to the ongoing business of such Grantor, each Grantor shall take all steps which it or the Agent deems reasonable and appropriate under the circumstances to preserve and protect each item of its

Intellectual Property Collateral, including, without limitation, maintaining the quality of any and all products or services used or provided in connection with any of the Trademarks, consistent with the quality of the products and services as of the date hereof, and taking all steps necessary to ensure that all licensed users of any of the Trademarks use such consistent standards of quality.

(f) With respect to its Intellectual Property Collateral, each Grantor agrees to execute an agreement, in substantially the form set forth in Exhibit B hereto (an “Intellectual Property Security Agreement”), for recording the security interest granted hereunder to the Agent in such Intellectual Property Collateral with the U.S. Patent and Trademark Office, the U.S. Copyright Office and any other governmental authorities necessary to perfect the security interest hereunder in such Intellectual Property Collateral.

(g) Each Grantor agrees that, should it obtain an ownership interest in any item of the type set forth in Section 1(g) which is not on the date hereof a part of the Intellectual Property Collateral (the “After-Acquired Intellectual Property”), (i) the provisions of Section 1 shall automatically apply thereto, (ii) any such After-Acquired Intellectual Property and, in the case of trademarks, the goodwill of the business connected therewith or symbolized thereby, shall automatically become part of the Intellectual Property Collateral subject to the terms and conditions of this Agreement with respect thereto, (iii) such Grantor shall give prompt written notice thereof to the Agent in accordance herewith and (iv) such Grantor shall execute and deliver to the Agent an IP Security Agreement Supplement covering such After-Acquired Intellectual Property as “Additional Collateral” thereunder and as defined therein, and shall record such IP Security Agreement Supplement with the U.S. Patent and Trademark Office, the U.S. Copyright Office and any other governmental authorities necessary to perfect the security interest hereunder in such After-Acquired Intellectual Property.

SECTION 11. Voting Rights; Dividends; Etc.

(a) So long as no Event of Default shall have occurred and be continuing:

(i) Each Grantor shall be entitled to exercise any and all voting and other consensual rights pertaining to the Security Collateral of such Grantor or any part thereof for any purpose; provided that such Grantor will not exercise or refrain from exercising any such right if such action would have a material adverse effect on the value of the Security Collateral or any part thereof.

(ii) Each Grantor shall be entitled to receive and retain any and all dividends, interest and other distributions paid in respect of the Security Collateral of such Grantor if and to the extent that the payment thereof is not otherwise prohibited by the terms of the Note Purchase Documents; provided that any and all dividends, interest and other distributions paid or payable other than in cash in respect of, and instruments and other property received, receivable or otherwise distributed in respect of, or in exchange for, any Security Collateral received after the date hereof, shall be, and shall be forthwith delivered to the Agent to hold as, Security Collateral and shall, if received by such Grantor, be received in trust for the benefit of the Agent, be segregated from the other property or funds of such Grantor and be forthwith delivered to the Agent as Security Collateral in the same form as so received (with any necessary endorsement).

(iii) The Agent will execute and deliver (or cause to be executed and delivered) to each Grantor all such proxies and other instruments as such Grantor may reasonably request for the purpose of enabling such Grantor to exercise the voting and other rights that it is entitled to exercise pursuant to paragraph (i) above and to receive the dividends or interest payments that it is authorized to receive and retain pursuant to paragraph (ii) above.

(b) Upon the occurrence and during the continuance of an Event of Default:

(i) All rights of each Grantor (x) to exercise or refrain from exercising the voting and other consensual rights that it would otherwise be entitled to exercise pursuant to Section 11(a)(i) shall, upon notice to such Grantor by the Agent, cease and (y) to receive the dividends, interest and other distributions that it would otherwise be authorized to receive and retain pursuant to Section 11(a)(ii) shall automatically cease, and all such rights shall thereupon become vested in the Agent, which shall thereupon have the sole right to exercise or refrain from exercising such voting and other consensual rights and to receive and hold as Security Collateral such dividends, interest and other distributions.

(ii) All dividends, interest and other distributions that are received by any Grantor contrary to the provisions of paragraph (i) of this Section 11(b) shall be received in trust for the benefit of the Agent, shall be segregated from other funds of such Grantor and shall be forthwith paid over to the Agent as Security Collateral in the same form as so received (with any necessary endorsement).

SECTION 12. Transfers and Other Liens; Additional Shares.

(a) Each Grantor agrees that it will not (i) sell, assign or otherwise dispose of, or grant any option with respect to, any of the Collateral, other than sales, assignments and other dispositions of Collateral, and options relating to Collateral, permitted under the terms of the Securities Purchase Agreement, or (ii) create or suffer to exist any Lien upon or with respect to any of the Collateral of such Grantor except for the pledge, assignment and security interest created under this Agreement and Permitted Liens.

(b) Each Grantor agrees that it will (i) cause each issuer of the Pledged Shares pledged by such Grantor not to issue any stock or other securities in addition to or in substitution for the Pledged Shares issued by such issuer, except to such Grantor, and (ii) pledge hereunder, immediately upon its acquisition (directly or indirectly) thereof, any and all additional shares of stock or other securities.

SECTION 13. Agent Appointed Attorney in Fact. Each Grantor hereby irrevocably appoints the Agent such Grantor’s attorney in fact, with full authority in the place and stead of such Grantor and in the name of such Grantor or otherwise, from time to time, upon the occurrence and during the continuance of an Event of Default, in the Agent’s discretion, to take any action and to execute any instrument that the Agent may deem necessary or advisable to accomplish the purposes of this Agreement, including, without limitation:

(a) to obtain and adjust insurance required to be paid to the Agent pursuant to Section 8,

(b) to ask for, demand, collect, ▇▇▇ for, recover, compromise, receive and give acquittance and receipts for moneys due and to become due under or in respect of any of the Collateral,

(c) to receive, endorse and collect any drafts or other instruments, documents and chattel paper, in connection with clause (a) or (b) above, and

(d) to file any claims or take any action or institute any proceedings that the Agent may deem necessary or desirable for the collection of any of the Collateral or otherwise to enforce the rights of the Agent with respect to any of the Collateral.

SECTION 14. Agent May Perform. If any Grantor fails to perform any agreement contained herein, the Agent may, as the Agent deems necessary to protect the security interest granted hereunder in the Collateral or to protect the value thereof, but without any obligation to do so and without notice, itself perform, or cause performance of, such agreement, and the expenses of the Agent incurred in connection therewith shall be payable by such Grantor under Section 17(b).

SECTION 15. The Agent’s Duties.

(a) The powers conferred on the Agent hereunder are solely to protect the Purchasers’ 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 Agent shall have no duty as to any Collateral, as to ascertaining or taking action with respect to calls, conversions, exchanges, maturities, tenders or other matters relative to any Collateral, whether or not any Purchaser has or is deemed to have knowledge of such matters, or as to the taking of any necessary steps to preserve rights against any parties or any other rights pertaining to any Collateral. The Agent shall be deemed to have exercised reasonable care in the custody and preservation of any Collateral in its possession if such Collateral is accorded treatment substantially equal to that which it accords its own property.

(b) Anything contained herein to the contrary notwithstanding, the Agent may from time to time, when the Agent deems it to be necessary, appoint one or more subagents (each a “Subagent”) for the Agent hereunder with respect to all or any part of the Collateral. In the event that the Agent so appoints any Subagent with respect to any Collateral, (i) the assignment and pledge of such Collateral and the security interest granted in such Collateral by each Grantor hereunder shall be deemed for purposes of this Agreement to have been made to such Subagent, in addition to the Agent, for the ratable benefit of the Purchasers, as security for the Secured Obligations of such Grantor, (ii) such Subagent shall automatically be vested, in addition to the Agent, with all rights, powers, privileges, interests and remedies of the Agent hereunder with respect to such Collateral, and (iii) the term “Agent,” when used herein in relation to any rights, powers, privileges, interests and remedies of the Agent with respect to such Collateral, shall include such Subagent; provided that no such Subagent shall be authorized to take any action with respect to any such Collateral unless and except to the extent expressly authorized in writing by the Agent.

SECTION 16. Remedies. If any Event of Default shall have occurred and be continuing:

(a) The Agent may exercise in respect of the Collateral, in addition to other rights and remedies provided for herein or otherwise available to it, all the rights and remedies of a Purchaser upon default under the UCC and also may: (i) require each Grantor to, and each Grantor hereby agrees that it will at its expense and upon request of the Agent forthwith, assemble all or part of the Collateral as directed by the Agent and make it available to the Agent at a place and time to be designated by the Agent that is reasonably convenient to both parties; (ii) without notice except as specified below, sell the Collateral or any part thereof in one or more parcels at public or private sale, 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 deem commercially reasonable; (iii) occupy any premises owned or leased by any of the Grantors where the Collateral or any part thereof is assembled or located for a reasonable period in order to effectuate its rights and remedies hereunder or under law, without obligation to such Grantor in respect of such occupation; and (iv) exercise any and all rights and remedies of any of the Grantors under or in connection with the Receivables and the Related Contracts or otherwise in respect of the Collateral, including, without limitation, any and all rights of such Grantor to demand or otherwise require payment of any amount under, or performance of any provision of, the Receivables and the Related Contracts. Each Grantor agrees that, to the extent notice of sale shall be required by law, at least ten days’ notice to such Grantor of the time and place of any public sale or the time after which any private sale is to be made shall constitute reasonable notification. The Agent shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. The 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.

(b) Any cash held by or on behalf of the Agent and all cash proceeds received by or on behalf of the Agent in respect of any sale of, collection from, or other realization upon all or any part of the Collateral may, in the discretion of the Agent, be held by the Agent as collateral for, and/or then or at any time thereafter applied (after payment of any amounts payable to the Agent pursuant to Section 17) in whole or in part by the Agent for the ratable benefit of the Purchasers against, all or any part of the Secured Obligations, in the following manner:

(i) first, to the Agent for any amounts as shall be required to reimburse the Agent for all reasonable costs and expenses incidental to the collection of the Liabilities and the enforcement or protection of the Agent’s security interest in the Collateral; and

(ii) second, to the payment in full of the other Secured Obligations, in each case equally and ratably in accordance with their respective amounts thereof then due and owing or as the Purchasers (including the Agent in respect of its Notes) holding the same may otherwise agree.

Any surplus of such cash or cash proceeds held by or on the behalf of the Agent and remaining after payment in full of all the Secured Obligations shall be paid over to the applicable Grantor or to whosoever may be lawfully entitled to receive such surplus.

(c) All payments received by any Grantor in respect of the Collateral shall be received in trust for the benefit of the Agent, shall be segregated from other funds of such Grantor and shall be forthwith paid over to the Agent in the same form as so received (with any necessary endorsement).

(d) The Agent may, without notice to any Grantor except as required by law and at any time or from time to time, charge, set off and otherwise apply all or any part of the Secured Obligations against any funds held in any deposit account of such Grantor.

(e) In the event of any sale or other disposition of any of the Intellectual Property Collateral of any Grantor, the goodwill of the business connected with and symbolized by any Trademarks subject to such sale or other disposition shall be included therein, and such Grantor shall supply to the Agent or its designee such Grantor’s know-how and expertise, and documents and things relating to any Intellectual Property Collateral subject to such sale or other disposition, and such Grantor’s customer lists and other records and documents relating to such Intellectual Property Collateral and to the manufacture, distribution, advertising and sale of products and services of such Grantor.

(f) If the Agent shall determine to exercise its right to sell all or any of the Security Collateral of any Grantor pursuant to this Section 16, such Security Collateral or the part thereof to be sold shall not, for any reason whatsoever, be effectively registered under Securities Act of 1933, as amended (as so amended the “Act”), the Agent may, in its discretion (subject only to applicable requirements of law), sell such Security Collateral or part thereof by private sale in such manner and under such circumstances as the Agent may deem necessary or advisable, but subject to the other requirements of this Section 16(f), and shall not be required to effect such registration or cause the same to be effected. Without limiting the generality of the foregoing, in any such event the Agent may, in its sole discretion, (i) in accordance with applicable securities laws, proceed to make such private sale notwithstanding that a registration statement for the purpose of registering such Security Collateral or part thereof could be or shall have been filed under the Act; (ii) approach and negotiate with a single possible purchaser to effect such sale; and (iii) restrict such sale to a purchaser who will represent and agree that such purchaser is purchasing for its own account, for investment, and not with a view to the distribution or sale of such Security Collateral or part thereof. In addition to a private sale as provided above in this Section 16(f), if any of such Security Collateral shall not be freely distributable to the public without registration under the Act at the time of any proposed sale hereunder, then the Agent shall not be required to effect such registration or cause the same to be effected but may, in its sole discretion (subject only to applicable requirements of law), require that any sale hereunder (including a sale at auction) be conducted subject to such restrictions as the Agent may, in its sole discretion, deem necessary or appropriate in order that such sale (notwithstanding any failure so to register) may be effected in compliance with the Debtor Relief Laws and other laws affecting the enforcement of creditors’ rights and the Act and all applicable state securities laws.

SECTION 17. Indemnity and Expenses.

(a) Each Grantor agrees to indemnify, defend and save and hold harmless the Agent and each other Purchaser and each of their respective Affiliates and their respective officers, directors, employees, agents, trustees and advisors (each, an “Indemnified Party”) from and against, and shall pay on demand, any and all claims, damages, losses, liabilities and expenses (including, without limitation, reasonable fees and expenses of counsel) that may be incurred by or asserted or awarded against any Indemnified Party, in each case arising out of or in connection with or resulting from this Agreement, except to the extent such claim, damage, loss, liability or expense resulted from such Indemnified Party’s gross negligence or willful misconduct.

(b) Each Grantor will upon demand pay to the Agent the amount of any and all reasonable expenses, including, without limitation, the reasonable fees and expenses of its counsel and of any experts and agents, that the Agent may incur in connection with (i) the administration of this Agreement, (ii) the custody, preservation, use or operation of, or the sale of, collection from or other realization upon, any of the Collateral of such Grantor, (iii) the exercise or enforcement of any of the rights of the Agent or the other Purchasers hereunder or (iv) the failure by such Grantor to perform or observe any of the provisions hereof.

SECTION 18. Amendments; Waivers; Additional Grantors; Etc.

(a) No amendment or waiver of any provision of this Agreement, and no consent to any departure by any Grantor herefrom, shall in any event be effective unless the same shall be in writing and signed by the Agent, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given. No failure on the part of the Agent or any other Purchaser to exercise, and no delay in exercising any right hereunder, 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.

(b) Upon the execution and delivery by any Person of a security agreement supplement in substantially the form of Exhibit A hereto (each a “Security Agreement Supplement”), (i) such Person shall be referred to as an “Additional Grantor” and shall be and become a Grantor hereunder and each reference in this Agreement and the other Note Purchase Documents to “Grantor” shall also mean and be a reference to such Additional Grantor, and (ii) the supplemental schedules I, II, III, IV, and V attached to each Security Agreement Supplement shall be incorporated into and become a part of and supplement Schedules I, II, III, IV, and V, respectively, hereto, and the Agent may attach such supplemental schedules to such Schedules; and each reference to such Schedules shall mean and be a reference to such Schedules as supplemented pursuant to each Security Agreement Supplement.

SECTION 19. Notices; Etc. All notices and other communications provided for hereunder shall be in writing and mailed, telecopied, e-mailed, or delivered to its address, telecopier number or e-mail address set forth opposite such Grantor’s or the Agent’s name on the signature pages hereto or on the signature page to the Security Agreement Supplement pursuant to which it became a party hereto; or, as to any party, at such other address, telecopier number or e-mail address as shall be designated by such party in a written notice to the other parties. All

such notices and other communications shall, when mailed, telecopied, e-mailed, or delivered, be effective when deposited in the mails or telecopied, sent by e-mail, or delivered, respectively, addressed as aforesaid; except that notices and other communications to the Agent shall not be effective until received by the Agent. Delivery by telecopier or by e-mail of an executed counterpart of any amendment or waiver of any provision of this Agreement or of any Security Agreement Supplement or Schedule hereto shall be effective as delivery of an original executed counterpart thereof.

SECTION 20. Continuing Security Interest; Assignments under the Securities Purchase Agreement. This Agreement shall create a continuing security interest in the Collateral and shall (a) remain in full force and effect until the payment in full of the Secured Obligations, (b) be binding upon each Grantor, its successors and assigns and (c) inure, together with the rights and remedies of the Agent hereunder, to the benefit of the Purchasers and their respective successors, transferees and assigns. Without limiting the generality of the foregoing clause (c), any Purchaser may assign or otherwise transfer all or any portion of its rights and obligations under the Securities Purchase Agreement as permitted thereunder to any other Person, and such other Person shall thereupon become vested with all the benefits in respect thereof granted to such Purchaser herein or otherwise, in each case as provided in the Securities Purchase Agreement.

SECTION 21. Termination. Upon the payment in full of the Secured Obligations, the pledge, assignment and security interest granted hereby shall terminate and all rights to the Collateral shall revert to the applicable Grantor. Upon any such termination, the Agent will, at the applicable Grantor’s expense, execute and deliver to such Grantor such documents as such Grantor shall reasonably request to evidence such termination.

SECTION 22. Security Interest Absolute. The obligations of each Grantor under this Agreement are independent of the Secured Obligations or any other obligations of any other Grantor under or in respect of the Note Purchase Documents, and a separate action or actions may be brought and prosecuted against each Grantor to enforce this Agreement, irrespective of whether any action is brought against any other Grantor or whether such other Grantor is joined in any such action or actions. All rights of the Agent and the other Purchasers and the pledge, assignment and security interest hereunder, and all obligations of each Grantor hereunder, shall be irrevocable, absolute and unconditional irrespective of, and each Grantor hereby irrevocably waives (to the maximum extent permitted by applicable law) any defenses it may now have or may hereafter acquire in any way relating to, any or all of the following:

(a) any lack of validity or enforceability of any Note Purchase Document or any other agreement or instrument relating thereto;

(b) any change in the time, manner or place of payment of, or in any other term of, all or any of the Secured Obligations or any other obligations of any other Grantor under or in respect of the Note Purchase Documents or any other amendment or waiver of or any consent to any departure from any Note Purchase Document, including, without limitation, any increase in the Secured Obligations resulting from the extension of additional credit to Company or otherwise;

(c) any taking, exchange, release or non perfection of any Collateral or any other collateral, or any taking, release or amendment or waiver of or consent to departure from any guaranty, for all or any of the Secured Obligations;

(d) any manner of application of any Collateral or any other collateral, or proceeds thereof, to all or any of the Secured Obligations, or any manner of sale or other disposition of any Collateral or any other collateral for all or any of the Secured Obligations;

(e) any change, restructuring or termination of the corporate structure or existence of any Grantor;

(f) any failure of any Purchaser to disclose to any Grantor any information relating to the business, condition (financial or otherwise), operations, performance, assets, nature of assets, liabilities or prospects of any other Grantor now or hereafter known to such Purchaser (each Grantor waiving any duty on the part of the Purchasers to disclose such information);

(g) the failure of any other Person to execute this Agreement or any other Note Purchase Document, guaranty or agreement or the release or reduction of liability of any Grantor or any guarantor or surety with respect to the Secured Obligations; or

(h) any other circumstance (including, without limitation, any statute of limitations) or any existence of or reliance on any representation by any Purchaser that might otherwise constitute a defense available to, or a discharge of, such Grantor or any other Grantor or a third party grantor of a security interest.

This Agreement shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of the Secured Obligations is rescinded or must otherwise be returned by any Purchaser or by any other Person upon the insolvency, bankruptcy or reorganization of any Grantor or otherwise, all as though such payment had not been made.

SECTION 23. Execution in Counterparts. This Agreement may be executed in any number of counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page to this Agreement by telecopier shall be effective as delivery of an original executed counterpart of this Agreement.

SECTION 24. Governing Law. This Agreement shall be governed by, and construed in accordance with, the law of the State of New York without regard to principles thereof regarding conflict of laws.
