Except as permitted by the Credit Agreement, none of the Debtors shall create, permit, or suffer to exist, and each of the Debtors shall defend the Collateral against, any Lien on the Collateral except the pledge and security interest of the Administrative Agent hereunder and except for Permitted Liens, and shall defend the Debtors’ rights in the Collateral and the Administrative Agent’s security interest in the Collateral against the claims of all persons and entities (other than any person or entity claiming by, through or under the Administrative Agent or any obligee of the Secured Obligations).

4.2 Sale of Collateral. None of the Debtors shall sell, assign, or otherwise dispose of the Collateral or any part thereof except as permitted by the Credit Agreement.

4.3 Perfection of Security Interest. Each Debtor shall execute and deliver to the Administrative Agent such agreements, assignments or instruments (including affidavits, notices, reaffirmations and amendments and restatements of existing documents, as the Administrative Agent may reasonably request) and do all such other things as the Administrative Agent may reasonably deem necessary (i) to assure to the Administrative Agent the effectiveness and priority of its security interests hereunder, including (A) such instruments as the Administrative Agent may from time to time reasonably request in order to perfect and maintain the security interests granted hereunder in accordance with the UCC, (B) with regard to Copyrights, a Notice of Grant of Security Interest in Copyrights for filing with the United States Copyright Office in the form of Schedule 4.3(a) attached hereto, (C) with regard to Patents, a Notice of Grant of Security Interest in Patents for filing with the United States Patent and Trademark Office in the form of Schedule 4.3(b) attached hereto and (D) with regard to Trademarks registered with the United States Patent and Trademark Office and all applications for Trademarks filed with the United States Patent and Trademark Office, a Notice of Grant of Security Interest in Trademarks for filing with the United States Patent and Trademark Office in the form of Schedule 4.3(c) attached hereto, (ii) to consummate the transactions contemplated hereby and (iii) to otherwise protect and assure the Administrative Agent of its rights and interests hereunder. To that end, each Debtor authorizes the Administrative Agent to file one or more financing statements (with collateral descriptions broader, including without limitation “all assets” and/or “all personal property” collateral descriptions, and/or less specific than the description of the Collateral contained herein) disclosing the Administrative Agent’s security interest in any or all of the Collateral of such Debtor without such Debtor’s signature thereon, and further each Debtor also hereby irrevocably makes, constitutes and appoints the Administrative Agent, its nominee or any other Person whom the Administrative Agent may designate, as such Debtor’s attorney-in-fact with full power and for the limited purpose to sign and/or file in the name of such Debtor any such financing statements (including renewal statements), amendments and supplements, notices or any similar documents that in the Administrative Agent’s reasonable discretion would be necessary or appropriate in order to perfect and maintain perfection of the security interests granted hereunder, such

power, being coupled with an interest, being and remaining irrevocable so long as the Secured Obligations remain unpaid and until the commitments relating thereto shall have been terminated. Each Debtor hereby agrees that a photographic or other reproduction of this Agreement or any such financing statement is sufficient for filing as a financing statement by the Administrative Agent without notice thereof to such Debtor wherever the Administrative Agent may in its sole discretion desire to file the same. In the event for any reason the Law of any jurisdiction other than New York becomes or is applicable to the Collateral of any Debtor or any part thereof, or to any of the Secured Obligations, such Debtor agrees to execute and deliver all such instruments and to do all such other things as the Administrative Agent reasonably deems necessary to preserve, protect and enforce the security interests of the Administrative Agent granted hereunder under the Law of such other jurisdiction (and, if a Debtor shall fail to do so promptly upon the request of the Administrative Agent, then the Administrative Agent may execute any and all such requested documents on behalf of such Debtor pursuant to the power of attorney granted hereinabove). If any Collateral is in the possession or control of a Debtor’s agents and the Administrative Agent so requests, such Debtor agrees to notify such agents in writing of the Administrative Agent’s security interest therein and, upon the Administrative Agent’s request, instruct them to hold all such Collateral for the account of the Secured Parties and subject to the Administrative Agent’s instructions.

4.4 Instruments/Tangible Chattel Paper/Documents. If any amount payable under and constituting Collateral shall be or become evidenced by any Instrument or Tangible Chattel Paper, or if any property constituting Collateral shall be stored or shipped subject to a Document, such Debtor shall (i) ensure that such Instrument, Tangible Chattel Paper or Document is either in the possession of such Debtor at all times or, if requested by the Administrative Agent, is promptly delivered to the Administrative Agent, duly endorsed in a manner satisfactory to the Administrative Agent and (ii) ensure that any Collateral consisting of Tangible Chattel Paper is marked with a legend acceptable to the Administrative Agent indicating the Administrative Agent’s security interest in such Tangible Chattel Paper.

4.6 Notification. Each of the Debtors shall promptly after it has knowledge thereof, notify the Administrative Agent of (i) any Lien upon or claim made or threatened against the Collateral other than Permitted Liens, (ii) any change in its name, state of incorporation or organization, its type of entity or its taxpayer identification number and (iii) a merger, consolidation or similar change in structure.

4.8 Books and Records. Each of the Debtors shall xxxx its books and records to reflect the security interest of the Administrative Agent for the benefit of the Secured Parties.

5.1 Power of Attorney. Each of the Debtors hereby irrevocably and with the power of substitution constitutes and appoints the Administrative Agent on behalf of the Secured Parties and any officer or agent thereof, with full power of substitution, as its true and lawful attorney-in-fact with full irrevocable power and authority in the place and stead and in the name of such Debtor or in its own name, from time to time in the Administrative Agent’s discretion during the continuance of an Event of Default and prior to the Collateral Termination Date, to take any and all action and to execute any and all documents and instruments which may be necessary or desirable to accomplish the purposes of this Agreement and, without limiting the generality of the foregoing, hereby gives the Administrative Agent the power and right on behalf of such Debtor and in its own name to do any of the following after the occurrence and during the continuance of an Event of Default and to the extent permitted by applicable Laws, without notice to or the consent of the Debtor:

(a)

to demand, xxx for, collect, or receive in the name of such Debtor or in its own name, any money or property at any time payable or receivable on account of or in exchange for any of the Collateral and, in connection therewith, endorse checks, notes, drafts, acceptances, money orders, or any other instruments for the payment of money under the Collateral;

agency upon such terms as the Administrative Agent may determine; (viii) to add or release any guarantor, endorser, surety, or other party to any of the Collateral or the Secured Obligations; (ix) to sell, transfer, pledge, make any agreement with respect to or otherwise deal with any of the Collateral as fully and completely as though the Administrative Agent were the absolute owner thereof for all purposes, and to do, at the Administrative Agent’s option and the Debtors’ expense (jointly and severally), at any time, or from time to time, all acts and things which the Administrative Agent deems necessary to protect, preserve, or realize upon the Collateral and the Administrative Agent’s security interest; (x) to execute and deliver all assignments, conveyances, statements, financing statements, renewal financing statements, security and pledge agreements, affidavits, notices and other agreements, instruments and documents that the Administrative Agent may reasonably deem appropriate in order to perfect and maintain the security interests and liens granted in this Agreement and in order to fully consummate all of the transactions contemplated herein; and (xi) to vote for a shareholder resolution, or to sign an instrument in writing, sanctioning the transfer of any or all of the Collateral into the name of the Administrative Agent or one or more of the Secured Parties or into the name of any transferee to whom the Collateral or any part thereof may be sold pursuant to Section 6.2 hereof.

This power of attorney is a power coupled with an interest and shall be irrevocable. The Administrative Agent shall be under no duty to exercise or withhold the exercise of any of the rights, powers, privileges, and options expressly or implicitly granted to the Administrative Agent in this Agreement, and shall not be liable for any failure to do so or any delay in doing so. The Administrative Agent shall not be liable for any act or omission or for any error of judgment or any mistake of fact or Law in its individual capacity or in its capacity as attorney-in-fact except acts or omissions constituting or resulting from its willful misconduct or gross negligence. This power of attorney is conferred on the Administrative Agent solely to protect, preserve, and realize upon its security interest in the Collateral.

5.2 Performance by the Administrative Agent of the Debtors’ Secured Obligations. On failure of any Debtor to perform any of the covenants and agreements contained herein, the Administrative Agent may, at its sole option and in its sole discretion, upon notice to the Debtors, perform the same and in so doing may expend such sums as the Administrative Agent may reasonably deem advisable in the performance thereof, including, without limitation, the payment of any insurance premiums, the payment of any taxes, a payment to obtain a release of a Lien or potential Lien, expenditures made in defending against any adverse claim and all other expenditures that the Administrative Agent may reasonably make for the protection of the security hereof or that it may be compelled to make by operation of Law. All such sums and amounts so expended shall be repayable by the Debtors on a joint and several basis (subject to Section 7.16 hereof) promptly upon timely notice thereof and demand therefor, shall constitute additional Secured Obligations and shall bear interest from the date said amounts are expended at the Default Rate. No such performance of any covenant or agreement by the Administrative Agent on behalf of any Debtor, and no such advance or expenditure therefor, shall relieve the Debtors of any default under the terms of this Security Agreement, the other Loan Documents or any other documents relating to the Secured Obligations. The Administrative Agent may make any payment hereby authorized in accordance with any xxxx, statement or estimate procured from the appropriate public office or holder of the claim to be discharged without inquiry into the accuracy of such xxxx, statement or estimate or into the validity of any tax assessment, sale, forfeiture, tax lien, title or claim except to the extent such payment is being contested in good faith by a Debtor in appropriate proceedings and against which adequate reserves are being maintained in accordance with GAAP.

5.3 The Administrative Agent’s Duty of Care. Other than the exercise of reasonable care in the physical custody of the Collateral while held by the Administrative Agent hereunder, the Administrative Agent shall have no responsibility for or obligation or duty with respect to all or any part

of the Collateral or any matter or proceeding arising out of or relating thereto, including, without limitation, any obligation or duty to collect any sums due in respect thereof or to protect or preserve any rights against prior parties or any other rights pertaining thereto, it being understood and agreed that the Debtors shall be responsible for preservation of all rights in the Collateral. Without limiting the generality of the foregoing, the Administrative Agent shall be conclusively deemed to have exercised reasonable care in the custody of the Collateral if the Administrative Agent takes such action, for purposes of preserving rights in the Collateral, as any of the Debtors may reasonably request in writing, but no failure or omission or delay by the Administrative Agent in complying with any such request by such Debtor, and no refusal by the Administrative Agent to comply with any such request by such Debtor, shall of itself be deemed to be a failure to exercise reasonable care.

5.4 Rights of Debtors; Debtors Remain Liable.

(a) Any term of this Agreement to the contrary notwithstanding, until written notice shall be given to any of the Debtors that the Administrative Agent is exercising its rights under this Section 5, such Debtor shall have the right, subject to the prohibitions contained in the Credit Agreement to possess, retain, enjoy and use the Collateral, to give consents, waivers or notifications with respect to the Collateral, to exercise its rights, powers and privileges under the Collateral, to agree to any modification of any of the terms of the Collateral, to dispose of any of the Collateral (it being agreed that the Lien of this Agreement shall attach to the proceeds thereof), and otherwise to act with respect to the Collateral in the ordinary course of business, in each case other than with respect to any Cash Collateral held by the Administrative Agent.

(b) Anything herein to the contrary notwithstanding, (i) each of the Debtors shall remain liable under the contracts and agreements included in the Collateral to the extent set forth therein (and subject to any defenses thereto), to perform all of its duties and obligations thereunder to the same extent as if this Agreement had not been executed, (ii) the exercise by the Administrative Agent of any of the rights hereunder shall not release any of the Debtors from any of its duties or obligations under the contracts and agreements included in the Collateral, and (iii) the Administrative Agent shall not have any obligation or liability under the contracts and agreements included in the Collateral solely by reason of this Agreement, nor shall the Administrative Agent be obligated to perform any of the obligations or duties of the Debtors thereunder or to take any action to collect or enforce any claim for payment assigned hereunder, in each case, solely by reason of this Agreement.

SECTION 6. Events of Default and Remedies.

6.1 Events of Default. The Debtors shall be in default under this Agreement upon the occurrence of and during the continuation of any of the events or conditions defined as Events of Default in the Credit Agreement (an “Event of Default”).

6.2 Rights and Remedies. Prior to the Collateral Termination Date, upon the occurrence of an Event of Default and so long as the same shall be continuing, the Administrative Agent shall have the following rights and remedies to the extent not prohibited by applicable Laws:

(a)

In addition to all other rights and remedies granted to the Administrative Agent in this Agreement and in any other instrument or agreement securing, evidencing, or relating to the Secured Obligations, the Administrative Agent shall have all of the rights and remedies of a secured party under the UCC of the jurisdiction applicable to the affected Collateral. Without limiting the generality of the foregoing, the Administrative Agent may (i) without demand or notice to the Debtors, collect, receive, or take possession of the Collateral or any part thereof, (ii) sell or otherwise dispose of the Collateral, or any

part thereof, in one or more parcels at public or private sale or sales, at the Administrative Agent’s offices or elsewhere, for cash, on credit, or for future delivery without assumption of any credit risk, and/or (iii) bid and become a purchaser at any such sale free of any right or equity of redemption in any of the Debtors, which right or equity is hereby expressly waived and released by all of the Debtors. Upon the request of the Administrative Agent, any of the Debtors shall assemble the Collateral and make it available to the Administrative Agent at any place designated by the Administrative Agent that is reasonably convenient to such Debtor and the Administrative Agent. Each of the Debtors agrees that the Administrative Agent shall not be obligated to give more than ten (10) days’ prior written notice of the time and place of any public sale or of the time after which any private sale may take place and that such notice shall constitute reasonable notice of such matters. Each of the Debtors shall be liable, jointly and severally, for all reasonable expenses of retaking, holding, preparing for sale, or the like, and all reasonable attorneys’ fees and other reasonable expenses incurred by the Administrative Agent in connection with the collection of the Secured Obligations and the enforcement of the Administrative Agent’s rights under this Agreement, in each case during the continuance of an Event of Default, all of which expenses and fees shall constitute additional Secured Obligations secured by this Agreement. The Administrative Agent may apply the Collateral against the Secured Obligations then due and payable in such order and manner as it shall elect in its sole discretion. Each of the Debtors shall remain liable for any deficiency (subject to Section 7.16 hereof) together with interest thereon at the Default Rate if the proceeds of any sale or disposition of the Collateral are insufficient to pay the Secured Obligations. Each of the Debtors waives all rights of marshaling in respect of the Collateral.

(b)

The Administrative Agent may cause any or all of the Collateral held by it to be transferred into the name of the Administrative Agent or the name or names of the Administrative Agent’s nominee or nominees (in each case as pledgee hereunder).

6.3 Access. In addition to the rights and remedies hereunder, upon the occurrence of an Event of Default and during the continuation thereof, the Administrative Agent shall have the right to enter and remain upon the various premises of the Debtors without cost or charge to the Administrative Agent, and use the same, together with materials, supplies, books and records of the Debtors for the purpose of collecting and liquidating the Collateral, or for preparing for sale and conducting the sale of the Collateral, whether by foreclosure, auction or otherwise. In addition, the Administrative Agent may remove Collateral, or any part thereof, from such premises and/or any records with respect thereto, in order to effectively collect or liquidate such Collateral.

6.4 Nonexclusive Nature of Remedies. Failure by the Administrative Agent or the holders of the Secured Obligations to exercise any right, remedy or option under this Agreement, any other Loan Document, any other documents relating to the Secured Obligations, or as provided by Law, or any delay by the Administrative Agent or the holders of the Secured Obligations in exercising the same, shall not operate as a waiver of any such right, remedy or option. No waiver hereunder shall be effective unless it is in writing, signed by the party against whom such waiver is sought to be enforced and then only to the extent specifically stated, which in the case of the Administrative Agent or the holders of the Secured Obligations shall only be granted as provided herein. To the extent permitted by Law, neither the Administrative Agent, the holders of the Secured Obligations, nor any party acting as attorney for the Administrative Agent or the holders of the Secured Obligations, shall be liable hereunder for any acts or omissions or for any error of judgment or mistake of fact or Law other than their gross negligence or willful misconduct hereunder. The rights and remedies of the Administrative Agent and the holders of the Secured Obligations under this Agreement shall be cumulative and not exclusive of any other right or remedy that the Administrative Agent or the holders of the Secured Obligations may have.

6.5 Retention of Collateral. To the extent permitted under applicable Law, in addition to the rights and remedies hereunder, upon the occurrence of an Event of Default, the Administrative Agent may, after providing the notices required by Sections 9-620 and 9-621 of the UCC or otherwise complying with the requirements of applicable Law of the relevant jurisdiction, accept or retain all or any portion of the Collateral in satisfaction of the Secured Obligations. Unless and until the Administrative Agent shall have provided such notices, however, the Administrative Agent shall not be deemed to have accepted or retained any Collateral in satisfaction of any Secured Obligations for any reason.

6.6 Application of Proceeds. Upon the occurrence and during the continuation of an Event of Default, any payments in respect of the Secured Obligations and any proceeds of the Collateral, when received by the Administrative Agent or any of the Secured Parties in cash or its equivalent, will be applied in reduction of the Secured Obligations in the order set forth in the Credit Agreement.

SECTION 7. Miscellaneous.

7.1 No Waiver, Cumulative Remedies. No failure on the part of the Administrative Agent on behalf of the Secured Parties to exercise and no delay in exercising, and no course of dealing with respect to, any right, power, privilege or remedy under this Agreement shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power, privilege or remedy under this Agreement preclude any other or further exercise thereof or the exercise of any other right, power, privilege or remedy. To the fullest extent permitted by applicable Laws, the rights, powers, privilege and remedies provided for in this Agreement are cumulative and not exclusive of any rights and remedies provided by Law. The Administrative Agent may exercise any right, power, privilege or remedy under this Agreement or under applicable Law against any Debtor without enforcing any rights, powers, privileges or remedies against any other Debtor under this Agreement or otherwise, each of the Debtors expressly waiving any rights or requirements that the Administrative Agent or any Lender first enforce any right, power, privilege or remedy against the Company, any other Debtor or any other Collateral for the Secured Obligations.

7.2 Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of each Debtor and the Administrative Agent and their respective successors, and assigns, except that none of the Debtors may assign any of its rights or obligations under this Agreement without the prior written consent of the Required Lenders under the Credit Agreement except to the extent permitted by the Credit Agreement. To the fullest extent permitted by Law, each Debtor hereby releases the Administrative Agent and each holder of the Secured Obligations, and their respective successors and assigns, from any liability for any act or omission relating to this Agreement or the Collateral, except for any liability arising from the gross negligence or willful misconduct of the Administrative Agent or such holder, or their respective officers, employees or agents.

EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PERSON HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PERSON WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

7.7 Survival of Representations and Warranties. All representations and warranties made in this Agreement or in any certificate delivered pursuant hereto shall survive the execution and delivery of this Agreement, and no investigation by the Administrative Agent or any Lender shall affect the representations and warranties or the right of the Administrative Agent or any Lender to rely upon them.

7.8 Amendments and Waivers. This Agreement and the provisions hereof may not be amended, waived, modified, changed, discharged or terminated except as set forth in Section 11.01 of the Credit Agreement.

7.9 Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

7.10 Severability. Any provision of this Agreement which 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 provisions of this Agreement, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

7.11 Construction. The Debtors and the Administrative Agent acknowledge that each of them has had the benefit of legal counsel of its own choice and has been afforded an opportunity to review this Agreement with its legal counsel and that this Agreement shall be construed as if jointly drafted by the Debtors and the Administrative Agent.

7.12 Secured Obligations Absolute. The obligations of the Debtors under this Agreement shall be absolute and unconditional and shall not be released, discharged, reduced, or in any way impaired by any circumstance whatsoever, including, without limitation, any amendment, modification, extension, or renewal of this Agreement, the Secured Obligations, or any document or instrument evidencing, securing, or otherwise relating to the Secured Obligations, or any release, subordination, or impairment of collateral, or any waiver, consent, extension, indulgence, compromise, settlement, or other action or inaction in respect of this Agreement, the Secured Obligations, or any document or instrument evidencing, securing, or otherwise relating to the Secured Obligations, or any exercise or failure to exercise any right remedy, power, or privilege in respect of the Secured Obligations.

Upon such release and redelivery, this Agreement shall terminate.

7.14 ENTIRE AGREEMENT. THIS AGREEMENT, TOGETHER WITH THE OTHER LOAN DOCUMENTS, EMBODIES THE FINAL, ENTIRE AGREEMENT AMONG THE PARTIES HERETO AND SUPERSEDES ANY AND ALL PRIOR COMMITMENTS, AGREEMENTS, REPRESENTATIONS, AND UNDERSTANDINGS, WHETHER WRITTEN OR ORAL, RELATING TO THE SUBJECT MATTER HEREOF.

7.15 Other Security. To the extent that any of the Secured Obligations are now or hereafter secured by property other than the Collateral (including, without limitation, real and other personal property owned by a Debtor), or by a guarantee, endorsement or property of any other Person in favor of the Administrative Agent on behalf of the Secured Parties, then the Administrative Agent shall have the right to proceed against such other property, guarantee or endorsement upon the occurrence and during the continuance of any Event of Default, and the Administrative Agent shall have the right, in its sole discretion, to determine which rights, security, liens, security interests or remedies the Administrative Agent shall at any time pursue, relinquish, subordinate, modify or take with respect thereto, without in any way modifying or affecting any of them or the Secured Obligations or any of the rights of the Administrative Agent or the holders of the Secured Obligations under this Agreement, under any of the other Loan Documents or under any other document relating to the Secured Obligations.

7.16 Joint and Several Obligations of Debtors.

(a) Each of the Debtors is accepting joint and several liability hereunder in consideration of the financial accommodation to be provided by the holders of the Secured Obligations, for the mutual benefit, directly and indirectly, of each of the Debtors and in consideration of the undertakings of each of the Debtors to accept joint and several liability for the obligations of each of them.

(b) Each of the Debtors jointly and severally hereby irrevocably and unconditionally accepts, not merely as a surety but also as a co-debtor, joint and several liability with the other Debtors with respect to the payment and performance of all of the Secured Obligations arising under this Agreement, the other Loan Documents and any other documents relating to the Secured Obligations, it being the intention of the parties hereto that all the Secured Obligations shall be the joint and several obligations of each of the Debtors without preferences or distinction among them.

(c) Notwithstanding any provision to the contrary contained herein, in any other of the Loan Documents or in any other documents relating to the Secured Obligations, the obligations of each Guarantor under the Credit Agreement, the other Loan Documents and the documents relating to the Secured Obligations shall be limited to an aggregate amount equal to the largest amount that would not render such obligations subject to avoidance under Section 548 of the United States Bankruptcy Code or any comparable provisions of any applicable state Law.

(d) Each of the Debtors agree, among themselves, that the provisions of Sections 4.06 and 4.08 of the Credit Agreement apply to any liabilities hereunder.
