                         (iii) Grantors acknowledge and agree that the Lender Group shall have no duties with respect to the Trademarks, Patents, Copyrights, or Intellectual Property Licenses.

Each Grantor acknowledges and agrees that, to the extent permitted by applicable law, all of the Collateral shall remain personal property regardless of the manner of its attachment or affixation to real property;

               (j) Transfers and Other Liens. Grantors shall not (i) sell, assign (by operation of law or otherwise) or otherwise dispose of, or grant any option with respect to, any of the Collateral, except expressly permitted by the Credit Agreement, or (ii) create or permit to exist any Lien upon or with respect to any of the Collateral of any of Grantors, except for Permitted Liens. The inclusion of Proceeds in the Collateral shall not be deemed to constitute Agent’s consent to any sale or other disposition of any of the Collateral except as expressly permitted in this Agreement or the other Loan Documents; and

               (k) Other Actions as to Any and All Collateral. Each Grantor shall promptly (and in any event within 2 Business Days of acquiring or obtaining such Collateral) notify Agent in writing upon (i) acquiring or otherwise obtaining any Collateral after the date hereof consisting of Trademarks, Patents, Copyrights, Intellectual Property Licenses, Investment Related Property, Chattel Paper (electronic, tangible or otherwise), documents (as defined in Article 9 of the Code), promissory notes (as defined in the Code, or instruments (as defined in the Code) or (ii) any amount payable under or in connection with any of the Collateral being or becoming evidenced after the date hereof by any Chattel Paper, documents, promissory notes, or instruments and, in each such case upon the request of Agent and in accordance with Section 8 hereof, promptly execute such other documents, or if applicable, deliver such Chattel Paper, other documents or certificates evidencing any Investment Related Property in accordance with Section 6 hereof and do such other acts or things deemed necessary or desirable by Agent to protect Agent’s Security Interest therein; and

The provisions of the Copyright Security Agreements, Trademark Security Agreements, and Patent Security Agreements are supplemental to the provisions of this Agreement, and nothing contained in the Copyright Security Agreements, Trademark Security Agreements, or the Patent Security Agreements shall limit any of the rights or remedies of Agent hereunder.

     8. Further Assurances.

               (a) Each Grantor agrees that from time to time, at its own expense, such Grantor will promptly execute and deliver all further instruments and documents, and take all further action, that may be necessary or that Agent may reasonably request, in order to perfect and protect any Security Interest granted or purported to be granted hereby or to enable Agent to exercise and enforce its rights and remedies hereunder with respect to any of the Collateral.

               (b) Each Grantor authorizes the filing by Agent financing or continuation statements, or amendments thereto, and such Grantor will execute and deliver to Agent such other instruments or notices, as may be necessary or as Agent may reasonably request, in order to perfect and preserve the Security Interest granted or purported to be granted hereby.

               (c) Each Grantor authorizes Agent at any time and from time to time to file, transmit, or communicate, as applicable, financing statements and amendments (i) describing the Collateral as “all personal property of debtor” or “all assets of debtor” or words of similar effect, (ii) describing the Collateral as being of equal or lesser scope or with greater detail, or (iii) that contain any information required by part 5 of Article 9 of the Code for the sufficiency or filing office acceptance. Each Grantor also hereby ratifies any and all financing statements or amendments previously filed by Agent in any jurisdiction.

               (d) Each Grantor acknowledges that it is not authorized to file any financing statement or amendment or termination statement with respect to any financing statement filed in connection with this Agreement without the prior written consent of Agent, subject to such Grantor’s rights under Section 9-509(d)(2) of the Code.

     9. Agent’s Right to Perform Contracts. Upon the occurrence and during the continuance of an Event of Default, Agent (or its designee) may proceed to perform any and all of the obligations of any Grantor contained in any contract, lease, or other agreement and exercise any and all rights of any Grantor therein contained as fully as such Grantor itself could.

     10. Agent Appointed Attorney-in-Fact. Each Grantor hereby irrevocably appoints Agent its attorney-in-fact, with full authority in the place and stead of such Grantor and in the name of such Grantor or otherwise, at such time as an Event of Default has occurred and is continuing under the Credit Agreement, to take any action and to execute any instrument which Agent may reasonably deem necessary or advisable to accomplish the purposes of this Agreement, including:

               (a) to ask, demand, collect, sue for, recover, compromise, receive and give acquittance and receipts for moneys due and to become due under or in connection with the Accounts or any other Collateral of such Grantor;

               (b) to receive and open all mail addressed to such Grantor and to notify postal authorities to change the address for the delivery of mail to such Grantor to that of Agent;

               (c) to receive, indorse, and collect any drafts or other instruments, documents, Negotiable Collateral or Chattel Paper;

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

               (e) to repair, alter, or supply goods, if any, necessary to fulfill in whole or in part the purchase order of any Person obligated to such Grantor in respect of any Account of such Grantor;

               (f) to use any labels, Patents, Trademarks, trade names, URLs, domain names, industrial designs, Copyrights, advertising matter or other industrial or intellectual property rights, in advertising for sale and selling Inventory and other Collateral and to collect any amounts due under Accounts, contracts or Negotiable Collateral of such Grantor; and

               (g) Agent on behalf of the Lender Group shall have the right, but shall not be obligated, to bring suit in its own name to enforce the Trademarks, Patents, Copyrights and Intellectual Property Licenses and, if Agent shall commence any such suit, the appropriate Grantor shall, at the request of Agent, do any and all lawful acts and execute any and all proper documents reasonably required by Agent in aid of such enforcement.

     To the extent permitted by law, each Grantor hereby ratifies all that such attorney-in-fact shall lawfully do or cause to be done by virtue hereof. This power of attorney is coupled with an interest and shall be irrevocable until this Agreement is terminated.

     11. Agent May Perform. If any of Grantors fails to perform any agreement contained herein, Agent may itself perform, or cause performance of, such agreement, and the reasonable expenses of Agent incurred in connection therewith shall be payable, jointly and severally, by Grantors.

     12. Agent’s Duties. The powers conferred on Agent hereunder are solely to protect Agent’s interest in the Collateral, for the benefit of the Lender Group and the Bank Product Provider, and shall not impose any duty upon Agent to exercise any such powers. Except for the safe custody of any Collateral in its actual possession and the accounting for moneys actually received by it hereunder, 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. Agent shall be deemed to have exercised reasonable care in the custody and preservation of any Collateral in its actual possession if such Collateral is accorded treatment substantially equal to that which Agent accords its own property.

     13. Collection of Accounts, General Intangibles and Negotiable Collateral. At any time upon the occurrence and during the continuation of an Event of Default, Agent or Agent’s designee may (a) notify Account Debtors of any Grantor that the Accounts, General Intangibles, Chattel Paper or Negotiable Collateral have been assigned to Agent, for the benefit of the Lender Group and the Bank Product Provider, or that Agent has a security interest therein, and (b) collect the Accounts, General Intangibles and Negotiable Collateral directly, and any collection costs and expenses shall constitute part of such Grantor’s Secured Obligations under the Loan Documents.

     14. Disposition of Pledged Interests by Agent. None of the Pledged Interests existing as of the date of this Agreement are, and none of the Pledged Interests hereafter acquired on the date of acquisition thereof will be, registered or qualified under the various federal or state securities laws of the United States and

disposition thereof after an Event of Default may be restricted to one or more private (instead of public) sales in view of the lack of such registration. Each Grantor understands that in connection with such disposition, Agent may approach only a restricted number of potential purchasers and further understands that a sale under such circumstances may yield a lower price for the Pledged Interests than if the Pledged Interests were registered and qualified pursuant to federal and state securities laws and sold on the open market. Each Grantor, therefore, agrees that: (a) if Agent shall, pursuant to the terms of this Agreement, sell or cause the Pledged Interests or any portion thereof to be sold at a private sale, Agent shall have the right to rely upon the advice and opinion of any nationally recognized brokerage or investment firm (but shall not be obligated to seek such advice and the failure to do so shall not be considered in determining the commercial reasonableness of such action) as to the best manner in which to offer the Pledged Interest or any portion thereof for sale and as to the best price reasonably obtainable at the private sale thereof; and (b) such reliance shall be conclusive evidence that Agent has handled the disposition in a commercially reasonable manner.

     15. Voting Rights.

               (a) Upon the occurrence and during the continuation of an Event of Default, (i) Agent may, at its option, and with 2 Business Days prior notice to any Grantor, and in addition to all rights and remedies available to Agent under any other agreement, at law, in equity, or otherwise, exercise all voting rights, and all other ownership or consensual rights in respect of the Pledged Interests owned by such Grantor, but under no circumstances is Agent obligated by the terms of this Agreement to exercise such rights, and (ii) if Agent duly exercises its right to vote any of such Pledged Interests, each Grantor hereby appoints Agent, such Grantor’s true and lawful attorney-in-fact and IRREVOCABLE PROXY to vote such Pledged Interests in any manner Agent deems advisable for or against all matters submitted or which may be submitted to a vote of shareholders, partners or members, as the case may be. The power-of-attorney granted hereby is coupled with an interest and shall be irrevocable.

               (b) For so long as any Grantor shall have the right to vote the Pledged Interests owned by it, such Grantor covenants and agrees that it will not, without the prior written consent of Agent, vote or take any consensual action with respect to such Pledged Interests which would materially adversely affect the rights of Agent and the other members of the Lender Group with respect to the Pledged Interests or the value of the Pledged Interests.

     16. Remedies. Upon the occurrence and during the continuance of an Event of Default:

               (a) Agent may exercise in respect of the Collateral, in addition to other rights and remedies provided for herein, in the other Loan Documents, or otherwise available to it, all the rights and remedies of a secured party on default under the Code or any other applicable law. Without limiting the generality of the foregoing, each Grantor expressly agrees that, in any such event, Agent without demand of performance or other demand, advertisement or notice of any kind (except a notice specified below of time and place of public or private sale) to or upon any of Grantors or any other Person (all and each of which demands, advertisements and notices are hereby expressly waived to the maximum extent permitted by the Code or any other applicable law), may take immediate possession of all or any portion of the Collateral and (i) require Grantors to, and each Grantor hereby agrees that it will at its own expense and upon request of Agent forthwith, assemble all or part of the Collateral as directed by Agent and make it available to Agent at one or more locations where such Grantor regularly maintains Inventory, and (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 Agent’s offices or elsewhere, for cash, on credit, and upon such other terms as Agent may deem commercially reasonable. Each Grantor agrees that, to the extent notice of sale shall be required by law, at least 10 days notice to any of Grantors 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 and specifically such notice shall constitute a reasonable “authenticated notification of disposition” within the meaning of Section 9-611 of the Code. Agent shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. 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) Agent is hereby granted a license or other right to use, without liability for royalties or any other charge, each Grantor’s labels, Patents, Copyrights, rights of use of any name, trade secrets, trade names, Trademarks, service marks and advertising matter, URLs, domain names, industrial designs, other industrial or intellectual property or any property of a similar nature, whether owned by any of Grantors or with respect to which any of Grantors have rights under license, sublicense, or other agreements, as it pertains to the Collateral, in preparing for sale, advertising for sale and selling any Collateral, and each Grantor’s rights under all licenses and all franchise agreements shall inure to the benefit of Agent.

               (c) Any cash held by Agent as Collateral and all cash proceeds received by Agent in respect of any sale of, collection from, or other realization upon all or any part of the Collateral shall be applied against the Secured Obligations in the order set forth in the Credit Agreement. In the event the proceeds of Collateral are insufficient to satisfy all of the Secured Obligations in full, each Grantor shall remain jointly and severally liable for any such deficiency.

               (d) Each Grantor hereby acknowledges that the Secured Obligations arose out of a commercial transaction, and agrees that if an Event of Default shall occur and be continuing Agent shall have the right to an immediate writ of possession without notice of a hearing. Agent shall have the right to the appointment of a receiver for the properties and assets of each of Grantors, and each Grantor hereby consents to such rights and such appointment and hereby waives any objection such Grantors may have thereto or the right to have a bond or other security posted by Agent.

     17. Remedies Cumulative. Each right, power, and remedy of Agent as provided for in this Agreement or in the other Loan Documents or now or hereafter existing at law or in equity or by statute or otherwise shall be cumulative and concurrent and shall be in addition to every other right, power, or remedy provided for in this Agreement or in the other Loan Documents or now or hereafter existing at law or in equity or by statute or otherwise, and the exercise or beginning of the exercise by Agent, of any one or more of such rights, powers, or remedies shall not preclude the simultaneous or later exercise by Agent of any or all such other rights, powers, or remedies.

     18. Marshaling. Agent shall not be required to marshal any present or future collateral security (including but not limited to the Collateral) for, or other assurances of payment of, the Secured Obligations or any of them or to resort to such collateral security or other assurances of payment in any particular order, and all of its rights and remedies hereunder and in respect of such collateral security and other assurances of payment shall be cumulative and in addition to all other rights and remedies, however existing or arising. To the extent that it lawfully may, each Grantor 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 Agent’s rights and remedies under this Agreement or under any other instrument creating or evidencing any of the Secured Obligations or under which any of the Secured Obligations is outstanding or by which any of the Secured Obligations is secured or payment thereof is otherwise assured, and, to the extent that it lawfully may, each Grantor hereby irrevocably waives the benefits of all such laws.

     19. Indemnity and Expenses.

               (a) Each Grantor agrees to indemnify Agent and the other members of the Lender Group from and against all claims, lawsuits and liabilities (including reasonable attorneys fees) growing out of or resulting from this Agreement (including enforcement of this Agreement) or any other Loan Document to which such Grantor is a party, except claims, losses or liabilities resulting from the gross negligence or willful misconduct of the party seeking indemnification as determined by a final non-appealable order of a court of

competent jurisdiction. This provision shall survive the termination of this Agreement and the Credit Agreement and the repayment of the Secured Obligations.

               (b) Grantors, jointly and severally, shall, upon demand, pay to Agent (or Agent, may charge to the Loan Account) all the Lender Group Expenses which Agent may incur in connection with (i) the administration of this Agreement, (ii) the custody, preservation, use or operation of, or, upon an Event of Default, the sale of, collection from, or other realization upon, any of the Collateral in accordance with this Agreement and the other Loan Documents, (iii) the exercise or enforcement of any of the rights of Agent hereunder or (iv) the failure by any of Grantors to perform or observe any of the provisions hereof.

     20. Merger, Amendments; Etc. THIS WRITTEN AGREEMENT, TOGETHER WITH THE OTHER LOAN DOCUMENTS, REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN AGREEMENTS BETWEEN THE PARTIES. No waiver of any provision of this Agreement, and no consent to any departure by any of Grantors herefrom, shall in any event be effective unless the same shall be in writing and signed by Agent, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given. No amendment of any provision of this Agreement shall be effective unless the same shall be in writing and signed by Agent and each of Grantors to which such amendment applies.

     21. Addresses for Notices. All notices and other communications provided for hereunder shall be given in the form and manner and delivered to Agent at its address specified in the Credit Agreement, and to any of the Grantors at their respective addresses specified in the Credit Agreement or Guaranty, as applicable, or, as to any party, at such other address as shall be designated by such party in a written notice to the other party.

     22. Continuing Security Interest: Assignments under Credit Agreement. This Agreement shall create a continuing security interest in the Collateral and shall (a) remain in full force and effect until the Obligations have been paid in full in cash in accordance with the provisions of the Credit Agreement and the Commitments have expired or have been terminated, (b) be binding upon each of Grantors, and their respective successors and assigns, and (c) inure to the benefit of, and be enforceable by, Agent, and its successors, transferees and assigns. Without limiting the generality of the foregoing clause (c), any the Lender may, in accordance with the provisions of the Credit Agreement, assign or otherwise transfer all or any portion of its rights and obligations under the Credit Agreement to any other Person, and such other Person shall thereupon become vested with all the benefits in respect thereof granted to such the Lender herein or otherwise. Upon payment in full in cash of the Obligations in accordance with the provisions of the Credit Agreement and the expiration or termination of the Commitments, the Security Interest granted hereby shall terminate and all rights to the Collateral shall revert to Grantors or any other Person entitled thereto. At such time, Agent will authorize the filing of appropriate termination statements to terminate such Security Interests. No transfer or renewal, extension, assignment, or termination of this Agreement or of the Credit Agreement, any other Loan Document, or any other instrument or document executed and delivered by any Grantor to Agent nor any additional Advances or other loans made by any the Lender to any Borrower, nor the taking of further security, nor the retaking or re-delivery of the Collateral to Grantors, or any of them, by Agent, nor any other act of the Lender Group or the Bank Product Provider, or any of them, shall release any of Grantors from any obligation, except a release or discharge executed in writing by Agent in accordance with the provisions of the Credit Agreement. Agent shall not by any act, delay, omission or otherwise, be deemed to have waived any of its rights or remedies hereunder, unless such waiver is in writing and signed by Agent and then only to the extent therein set forth. A waiver by Agent of any right or remedy on any occasion shall not be construed as a bar to the exercise of any such right or remedy which Agent would otherwise have had on any other occasion.

     23. Governing Law.

               (a) THE VALIDITY OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS (UNLESS EXPRESSLY PROVIDED TO THE CONTRARY IN ANOTHER LOAN DOCUMENT IN RESPECT OF SUCH OTHER LOAN DOCUMENT), THE CONSTRUCTION, INTERPRETATION, AND ENFORCEMENT HEREOF AND THEREOF, AND THE RIGHTS OF THE PARTIES HERETO AND THERETO WITH RESPECT TO ALL MATTERS ARISING HEREUNDER OR THEREUNDER OR RELATED HERETO OR THERETO SHALL BE DETERMINED UNDER, GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF CALIFORNIA.

To the extent required by Section 5.16 of the Credit Agreement, any new direct or indirect Subsidiary (whether by acquisition or creation) of Grantor is required to enter into this Agreement by executing and delivering in favor of Agent a supplement to this Agreement in the form of Annex 1 attached hereto. Upon the execution and delivery of Annex 1 by such new Subsidiary, such Subsidiary shall become a Grantor hereunder with the same force and effect as if originally named as a Grantor herein. The execution and delivery of any instrument adding an additional Grantor as a party to this Agreement shall not require the consent of any Grantor hereunder. The rights and obligations of each Grantor hereunder shall remain in full force and effect notwithstanding the addition of any new Grantor hereunder.

     25. Agent. Each reference herein to any right granted to, benefit conferred upon or power exercisable by the “Agent” shall be a reference to Agent, for the benefit of the Lender Group and the Bank Product Provider.

Delivery of an executed counterpart of this Agreement by telefacsimile or other electronic method of transmission shall be

equally as effective as delivery of an original executed counterpart of this Agreement.

Any signatures delivered by a party by facsimile transmission or by e-mail transmission shall be deemed an original signature hereto.

     7. CONSTRUCTION. Unless the context of this Trademark Security Agreement or any other Loan Document clearly requires otherwise, references to the plural include the singular, references to the singular include the plural, the terms “includes” and “including” are not limiting, and the term “or” has, except where otherwise indicated, the inclusive meaning represented by the phrase “and/or.” The words “hereof,” “herein,” “hereby,” “hereunder,” and similar terms in this Trademark Security Agreement or any other Loan Document refer to this Trademark Security Agreement or such other Loan Document, as the case may be, as a whole and not to any particular provision of this Trademark Security Agreement or such other Loan Document, as the case may be. Section, subsection, clause, schedule, and exhibit references herein are to this Agreement unless otherwise specified. Any reference in this Trademark Security Agreement or in any other Loan Document to any agreement, instrument, or document shall include all alterations, amendments, changes, extensions, modifications, renewals, replacements, substitutions, joinders, and supplements, thereto and thereof, as applicable (subject to any restrictions on such alterations, amendments, changes, extensions, modifications, renewals, replacements, substitutions, joinders, and supplements set forth herein). Any

reference herein or in any other Loan Document to the satisfaction or repayment in full of the Obligations shall mean the repayment in full in cash (or cash collateralization in accordance with the terms hereof) of all Obligations other than unasserted contingent indemnification Obligations and other than any Bank Product Obligations that, at such time, are allowed by the applicable Bank Product Provider to remain outstanding and that are not required by the provisions of the Credit Agreement to be repaid or cash collateralized. Any reference herein to any Person shall be construed to include such Person’s successors and assigns. Any requirement of a writing contained herein or in any other Loan Document shall be satisfied by the transmission of a Record and any Record so transmitted shall constitute a representation and warranty as to the accuracy and completeness of the information contained therein.
