(a) The guarantee contained in this Article 3 shall continue to be effective, or be reinstated, as the case may be, if at any time payment, or any part thereof, of any of the Obligations is rescinded or recovered directly or indirectly from Lender or its respective successors, indorsees, transferees, and assignees as a preference, fraudulent transfer or otherwise, or must otherwise be restored or returned by Lender upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of Borrower or any Guarantor, or upon or as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for, Borrower or any Guarantor or any substantial part of its property, or otherwise, all as though such payments had not been made.

(b) So long as any Obligations remain outstanding, no Guarantor shall, without the prior written consent of Lender, commence or join with any other Person in commencing any bankruptcy, reorganization or insolvency case or proceeding of or against Borrower or any other Guarantor.

To effectuate the foregoing intention, Lender and the Guarantors hereby irrevocably agree that the obligations of such Guarantor shall be limited to the maximum amount that shall, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this Article 3, result in the obligations of such Guarantor under its Subsidiary Guarantee not constituting a fraudulent transfer or conveyance.

5.2 Perfection of Security Interests

(a) Filing of Financing Statements. Without limiting any rights of Lender under the UCC, each Grantor hereby authorizes Lender to file one or more financing or continuation statements, and amendments thereto, including one or more financing statements indicating that such financing statements cover all assets or all personal property (or words of similar effect) of such Grantor, in each case without the signature of such Grantor, and regardless of whether any particular asset described in such financing statements falls within the scope of the UCC or the granting clause of this Agreement.

(b) PTO Filings. On a continuing basis, each Grantor shall make, execute, acknowledge and deliver, and file and record in the proper filing and recording places, all such instruments and documents, including any documents for filing with the PTO, the Copyright Office or any applicable state office as Lender may reasonably request. Lender may record this Agreement, an abstract thereof, or any other document describing Lender’s interest in the Collateral with the PTO or the Copyright Office at the expense of Lender.

5.3 Duration of Security Interest

. Each Grantor agrees that this Agreement shall create a continuing security interest in the Collateral which shall remain in effect until the payment in full and the satisfaction of all Obligations, whereupon such security interest shall terminate. Notwithstanding anything to the contrary herein, the security interest created by this Agreement (including all representations, warranties and covenants contained herein) shall continue to be effective or be reinstated, as the case may be, if at any time any amount received by Lender in respect of the Obligations is rescinded or must otherwise be restored or returned by Lender or its respective successors, indorsees, transferees and assignees as a preference, fraudulent transfer or otherwise, or must be restored or redeemed by Lender upon or as a result of, the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for any Grantor or any substantial part of its property, or otherwise, all as though such payments had not been made. Upon termination of the security interest, Lender shall, at the Grantors’ sole cost and expense, execute such further documents and take such further actions as may be necessary to effect the release contemplated by this Section 5.3, including duly executing and delivering termination statements for filing in all relevant jurisdictions under the UCC. Notwithstanding anything to the contrary herein, upon the factoring of any of the Grantor’s accounts and receivables in the ordinary course of business and consistent with past practices, Lender’s security interest in such accounts and receivables will be automatically released and of no further force and effect.

- 17 -

5.4 Possession of Collateral

. So long as no Event of Default has occurred and is continuing, each Grantor shall remain in full possession, enjoyment and control of its Collateral (except only as may be otherwise required by Lender for perfection of its security interest therein) and shall be entitled to manage, operate and use the same and each part thereof with the rights and franchises appertaining thereto; provided, however, that the possession, enjoyment, control and use of the Collateral shall at all times be subject to the observance and performance of the terms of this Agreement.

5.5 Delivery of Additional Documentation Required

. Each Grantor shall from time to time execute and deliver to Lender, all documents Lender may reasonably request, in form satisfactory to Lender, to perfect and continue Lender’s first priority, perfected security interests in the Collateral (subject to Permitted Liens) and in order to consummate fully all of the transactions contemplated under the Loan Documents.

5.7 Authorization to Supplement

Such Grantor(s) shall give prompt notice in writing to Lender with respect to any such new Intellectual Property rights. Without limiting the Grantors’ obligations under this Section 5.7, each Grantor authorizes Lender unilaterally to modify this Agreement by amending Schedule 6.8 to include any such new patent rights.

Upon the occurrence and during the continuance of an Event of Default, to the extent permitted by law, each Grantor covenants that it will not at any time insist upon or plead, or in any manner whatever claim or take any benefit or advantage of, any stay or extension law now or at any time hereafter in force, nor claim, take nor insist upon any benefit or advantage of or from any law now or hereafter in force providing for the valuation or appraisement of the Collateral or any part thereof prior to any sale or sales thereof to be made pursuant to any provision herein contained, or to the decree, judgment or order of any court of competent jurisdiction; nor, after such sale or sales, claim or exercise any right under any statute now or hereafter made or enacted by any state or otherwise to redeem the Property so sold or any part thereof, and, to the full extent legally permitted, except as to rights expressly provided herein, hereby expressly waives for itself and on behalf of each and every Person, except decree or judgment creditors of such Grantor acquiring any interest in or title to the Collateral or any part thereof subsequent to the date of this Agreement, all benefit and advantage of any such law or laws, and covenants that it will not invoke or utilize any such law or laws or otherwise hinder, delay or impede the execution of any power herein granted and delegated to Lender, but will suffer and permit the execution of every such power as though no such power, law or laws had been made or enacted.

10.3 Lender to Hold in Trust

. Upon the occurrence and during the continuance of an Event of Default, each Grantor will, upon receipt by it of any revenue, income, profits or other sums in which a security interest is granted hereunder, payable pursuant to any agreement or otherwise, or of any check, draft, note, trade acceptance or other instrument evidencing an obligation to pay any such sum, hold the sum or instrument in trust for Lender, segregate such sum or instrument from its own assets and forthwith, without any notice, demand or other action whatsoever (all notices, demands, or other actions on the part of the Lender being expressly waived), endorse, transfer and deliver any such sums or instruments or both, to Lender to be applied to the repayment of the Loans in accordance with the provisions of this Agreement.

10.4 Effect of Sale

. Any sale, whether under any power of sale hereby given or by virtue of judicial proceedings, shall operate to divest all right, title, interest, claim and demand whatsoever, either at law or in equity, of Grantors in and to the Property sold, and shall be a perpetual bar, both at law and in equity, against Grantors, their successors and assigns, and against any and all Persons claiming the Property sold or any part thereof under, by or through Grantors, their successors or assigns.

10.5 Power of Attorney in Respect of the Collateral

. Each Grantor does hereby irrevocably appoint Lender (which appointment is coupled with an interest) on the occurrence and continuance of an Event of Default, the true and lawful attorney in fact of such Grantor with full power of substitution, for it and in its name: (a) to ask, demand, collect, receive, receipt for, ▇▇▇ for, compound and give acquittance for any and all rents, issues, profits, avails, distributions, income, payment draws and other sums in which a security interest is granted under Section 5 with full power to settle, adjust or compromise any

- 27 -

claim thereunder as fully as if Lender were a “Grantor” itself, (b) to receive payment of and to endorse the name of a Grantor to any items of Collateral (including checks, drafts and other orders for the payment of money) that come into Lender’s possession or under Lender’s control, (c) to make all demands, consents and waivers, or take any other action with respect to, the Collateral, (d) in Lender’s discretion to file any claim or take any other action or proceedings, either in its own name or in the name of such Grantor or otherwise, which Lender may reasonably deem necessary or appropriate to protect and preserve the right, title and interest of Lender in and to the Collateral, or (e) to otherwise act with respect thereto as though Lender were the outright owner of the Collateral.

10.6 Remedies Cumulative

. Lender’s rights and remedies under this Agreement, the Loan Documents, and all other agreements shall be cumulative. Lender shall have all other rights and remedies not inconsistent herewith as provided under the UCC, by law, or in equity. No exercise by Lender of one right or remedy shall be deemed an election, and no waiver by Lender of any Event of Default on Borrower’s part shall be deemed a continuing waiver. No delay by Lender shall constitute a waiver, election, or acquiescence by it.

10.7 Application of Collateral Proceeds

. The Proceeds of the Collateral, or any part thereof, and the proceeds and the avails of any remedy hereunder (as well as any other amounts of any kind held by Lender at the time of or received by Lender after, the occurrence of an Event of Default hereunder) shall be paid to and applied as follows:

(a) First, to the payment of any Lender’s Expenses;

(b) Second, to the payment to Lender of the amount then owing or unpaid on the Loans and all other Obligations with respect to each Loan, and if such proceeds shall be insufficient to pay in full the whole amount so due, owing or unpaid upon the Loans, then to the unpaid interest thereon, then to the unpaid principal amount of the Loans, and then to the payment of other amounts then payable to Lender under any of the Loan Documents; and

(c) Third, to the payment of the surplus, if any, to the applicable Grantor, its successors and assigns, or to whomsoever may be lawfully entitled to receive the same.

10.8 Reinstatement of Rights

. If Lender shall have proceeded to enforce any right under this Agreement or any other Loan Document by foreclosure, sale, entry or otherwise, and such proceedings shall have been discontinued or abandoned for any reason or shall have been determined adversely, then and in every such case (unless otherwise ordered by a court of competent jurisdiction), Lender shall be restored to its former position and rights hereunder with respect to the Property subject to the security interest created under this Agreement.

10.9 Lender’s Liability for Collateral

- 28 -

. So long as Lender complies with its obligations, if any, under Section 9207 of the UCC, Lender shall not in any way or manner be liable or responsible for: (a) the safekeeping of the Collateral; (b) any loss or damage thereto occurring or arising in any manner or fashion from any cause; (c) any diminution in the value thereof; or (d) any act or default of any carrier, warehouseman, bailee, forwarding agency, or other Person whomsoever. All risk of loss, damage or destruction of the Collateral shall be borne by Grantors.

10.10 Demand; Protest

. Borrower waives demand, protest, notice of protest, notice of default or dishonor, notice of payment and nonpayment, notice of any default, nonpayment at maturity, release, compromise, settlement, extension, or renewal of accounts, documents, instruments, chattel paper, and guarantees at any time held by Lender on which Borrower may in any way be liable.

RECITALS

A. Lender has agreed to make certain advances of money from time to time and to extend certain financial accommodations to Borrower (the “Loan”) in the amount and manner set forth in that certain Second Loan and Security Agreement dated as of June 19, 2006 by and between Lender, Borrower and Guarantors (as the same may be amended, modified or supplemented from time to time, the “Loan Agreement”). Capitalized terms not otherwise defined herein shall have the meanings ascribed to such terms in the Loan Agreement. Lender is willing to make the Loan to Borrower, but only upon the condition, among others, that Borrower shall grant to Lender a security interest in all of its copyrights, trademarks and patents to secure the obligations of Borrower under the Loan Agreement.

B. Pursuant to the terms of the Loan Agreement, Borrower has granted to Lender a security interest in all of Borrower’s right, title and interest, whether presently existing or hereafter acquired, in, to and under all of the Collateral, including, without limitation, all of its copyrights, trademarks and patents.

NOW, THEREFORE, for good and valuable consideration, receipt of which is hereby acknowledged, and intending to be legally bound, as collateral security for the prompt and complete payment when due of its obligations under the Loan Agreement and the other Loan Documents, Borrower hereby represents, warrants, covenants and agrees as follows:

AGREEMENT

To secure its obligations under the Loan Documents and under all other agreements now existing or hereafter arising between Borrower and Lender, Borrower assigns to Lender for security purposes, and grants and pledges to Lender, a security interest in all of Borrower’s right, title and interest in, to and under its Intellectual Property Collateral (including, without limitation, those copyrights, patents and trademarks listed on Schedules A, B and C hereto), together with the goodwill of the businesses associated with the trademarks, and including, without limitation, all proceeds thereof (such as, by way of example but not by way of limitation, license royalties and proceeds of infringement suits), the right to ▇▇▇ for past, present and future infringements, all rights corresponding thereto throughout the world and all re-issues, re-examinations, divisions continuations, renewals, termination rights, extensions and continuations-in-part thereof.

This security interest is granted in conjunction with the security interest granted to Lender under the Loan Agreement. The rights and remedies of Lender with respect to the security interest granted hereby are in addition to those set forth in the Loan Agreement and the

A-

other Loan Documents, and those which are now or hereafter available to Lender as a matter of law or equity. Each right, power and remedy of Lender provided for herein or in the Loan Agreement or any of the Loan Documents, or now or hereafter existing at law or in equity shall be cumulative and concurrent and shall be in a addition to every right, power or remedy provided for herein and the exercise by Lender of any one or more of the rights, powers or remedies provided for in this Agreement, the Loan Agreement or any of the other Loan Documents, or now or hereafter existing at law or in equity, shall not preclude the simultaneous or later exercise by any person or entity, including Lender, of any or all other rights, powers or remedies.

Borrower represents and warrants that Schedules A, B, and C attached hereto set forth any and all intellectual property rights in connection to which Borrower has registered or filed an application with either the United States Patent and Trademark Office or the United States Copyright Office, as applicable.

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 counterparts together shall constitute one and the same instrument.

THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES UNDER THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE INTERNAL LAWS OF THE STATE OF CALIFORNIA WITHOUT GIVING EFFECT TO ANY CONFLICT OF LAW PROVISIONS, EXCEPT TO THE EXTENT GOVERNED BY FEDERAL LAW, IN WHICH CASE FEDERAL LAW SHALL APPLY.

This Agreement may not be amended, supplemented or modified, nor may the obligations of the parties hereto be waived, except pursuant to a writing signed by both Lender and Borrower.

Borrower may not assign its rights or obligations under this Agreement or otherwise encumber or hypothecate its Intellectual Property Collateral without the consent of Lender. This Agreement shall be binding upon and inure to the benefit of Lender and Borrower and their respective successors and permitted assigns.
