- 7 - Administrative Agent from time to time, promptly (but in any event within five (5) Business Days after receipt of request) take whatever actions are requested by Administrative Agent in regard thereto, including, in the case of Consignments made by such Credit Party, to cause such Credit Party’s security interest in and to such consigned Goods to be perfected (with such priority as Administrative Agent may require) in accordance with the UCC and assigned to Administrative Agent in accordance with the UCC. Without limiting the generality of the foregoing, at Administrative Agent’s reasonable request, for any Consignments made by such Credit Party, such Credit Party shall (i) file a Financing Statement in respect of such Inventory naming itself as “Consignor” and such Person as “Consignee” thereon, in the jurisdiction of such Consignee’s incorporation (or organization), and assign such Financing Statement to Administrative Agent, (ii) cause such Consignee (and, if requested by Administrative Agent, any secured lender to, or landlord (or mortgagee) of, such Consignee to execute and deliver to Administrative Agent a Third Party Claimant Agreement in form and content satisfactory to Administrative Agent in respect of such Inventory.

Without limitation of the foregoing, anything contained herein to the contrary notwithstanding, (a) each Credit Party shall remain liable under any contracts and agreements included in the Collateral, to the extent set forth therein, to perform all of its duties and obligations thereunder to the same extent as if this Agreement had not been executed, (b) the exercise by Administrative Agent of any of its rights hereunder shall not release any Credit Party from any of its duties or obligations under the contracts and agreements included in the Collateral, and (c) Administrative Agent shall not have any obligation or liability under any contracts, licenses, and agreements included in the Collateral by reason of this Agreement, nor shall Administrative Agent be obligated to perform any of the obligations or duties of any Credit Party thereunder or to take any action to collect or enforce any claim for payment assigned hereunder.

At any time after the occurrence of the Springing Covenant Date, if any Credit Party acquires any Material Real Estate or any Real Estate becomes Material Real Estate through an appraisal or otherwise, the Credit Parties shall execute and deliver to Administrative Agent (or such trustee) all Mortgages and Mortgage Documents in form and substance reasonably satisfactory to Administrative Agent in connection with such acquired or other Material Real Estate within ninety (90) days after the date of such acquisition or other event (or such later date as may be agreed to by the Administrative Agent in writing in its discretion). All Mortgages shall be executed by the applicable Credit Party in favor of Administrative Agent (or its trustee created for such purpose), for the benefit of Secured Parties, and in each case shall be duly recorded, at Credit Parties’ expense, in each office where such recording is required to constitute a fully perfected, first priority Lien upon such Material Real Estate covered thereby (subject

- 8 - to Permitted Real Estate Encumbrances and other Permitted Liens) as security for the payment or performance of the Obligations, together with receipt (and recording, as applicable) by Administrative Agent of all applicable Mortgage Documents in connection therewith. Section 8. Power of Attorney. Each Credit Party hereby constitutes and appoints Administrative Agent (and all Persons so designated from time to time by Administrative Agent) as such Credit Party’s true and lawful attorney (and agent-in-fact) for the purposes provided in this Section 8, which power of attorney is coupled with an interest and is, therefore, irrevocable.

Each Credit Party further hereby authorizes Administrative Agent to file one or more financing or continuation statements, and amendments thereto, relative to all or any part of the Collateral without notice to, or consent of, any Credit Party (it being understood by the parties hereto that, with respect to any financing statements to be filed for As-Extracted Collateral, as of the Closing Date, Credit Parties have only provided information regarding Material Real Estate and Material Leased Real Estate for purposes of filing financing statements covering As-Extracted Collateral). Section 12. Particular Covenants Relating to Accounts. Until Payment in Full of the Obligations, each Credit Party shall, and shall cause each Subsidiary, as applicable, to: (a) Taxes. During the existence of an Event of Default, authorize Administrative Agent, if an Account of any Credit Party includes a charge for any unpaid Taxes, to pay the amount thereof (and any penalty thereon) to the proper taxing authority for the account of such Credit Party and to charge Borrowers’ account therefor; provided, however, that Administrative Agent shall not be obligated to pay, or otherwise be liable, for any Taxes that may be due from any Credit Party or with respect to any Collateral. (b) Account Verification. Cooperate fully with Administrative Agent in facilitating Administrative Agent’s verification of the validity, amount, or any other matter relating to any Accounts of Credit Parties, and each Credit Party, for itself and on behalf of each of its Subsidiaries, grants Administrative Agent the right, after an Event of Default has occurred and is continuing, and in the name of Administrative Agent, any designee of Administrative Agent, or such Credit Party or Subsidiary, to complete such verification by mail, telephone, or otherwise. (c) Assignments of Accounts. If so requested by Administrative Agent from time to time during the existence of an Event of Default, promptly (but in any event within five (5) Business Days after requested to do so), execute and deliver to Administrative Agent formal, written assignments of all of such Credit Parties’ Accounts which have not, as of such date been included in any such formal, written assignment. Section 13. Particular Covenants Regarding Inventory. Until Payment in Full of the Obligations, each Credit Party shall, and shall cause each Subsidiary, as applicable, to: (a) Records and Reports of Inventory. Keep accurate and complete records of its Inventory, including costs and daily withdrawals and additions. (b) Inventory Examinations. Conduct a physical inventory at least once per calendar year (and, during the existence of an Event of Default, at such other time or times as may be requested by Administrative Agent, as soon as practicable but in any event within thirty (30) days after such request) and periodic cycle counts consistent with historical practices and, if requested by Administrative Agent, provide to Administrative Agent a report based on each such physical inventory and count promptly upon completion thereof (but in any event within five (5) Business Days after completion), with such supporting

- 12 - information as Administrative Agent may request. Administrative Agent may (but shall have no duty to) participate in and observe each physical inventory and cycle count. (c) [Reserved].

(i) Keep accurate and complete records of its Equipment; and (ii) promptly upon reasonable request (but in any event within five (5) Business Days after receipt of request) by Administrative Agent, deliver to Administrative Agent evidence of Credit Parties’ or Subsidiaries’ ownership or interests in any such Equipment. (b) Condition of Equipment. (i) Keep all Equipment in good operating condition and repair, and make all necessary replacements and repairs so that the value and operating efficiency of the Equipment is preserved at all times, reasonable wear and tear excepted; (ii) ensure that the Equipment is mechanically and structurally sound and capable of performing the functions for which it was designed in accordance with manufacturer specifications; and (iii) prevent any material Equipment from becoming affixed to Real Estate unless each applicable Third Party Claimant shall have executed and delivered a Third Party Claimant Agreement in regard thereto. Section 15. Remedies upon Default. (a) In addition to (and not in lieu of) the rights and remedies specified in Section 11.2 of the Credit Agreement, at any time and from time to time during the existence of any Event of Default, Administrative Agent may (and, at the written direction of the Required Lenders, shall) do any one or more or all of the following: (i) (A) take possession of any Collateral; (B) on demand, require Credit Parties to assemble Collateral, at Credit Parties’ expense, and make it available to Administrative Agent (or its designee) at a time and place designated by Administrative Agent; (C) enter any premises where Collateral is located and store Collateral on such premises until sold (and if the premises are owned or leased by a Credit Party, such Credit Party shall not charge for such storage, and will reimburse Administrative Agent for any such charges imposed by any other Person in regard thereto); (D) sell, lease, or otherwise dispose of any Collateral in its then condition or after the refurbishing, restoration, repair, or further manufacturing or processing thereof (at Credit Parties’ expense), at public or private sale, with only such notice as may be required by Applicable Law, in lots or in bulk, and at such locations, all as Administrative Agent, in its discretion, deems advisable, and at such prices or terms as Administrative Agent may deem reasonable, for cash, upon credit, or for future delivery; (E) demand, collect, invoice, and sue for all amounts owed pursuant to Accounts, General Intangibles, Chattel Paper, Instruments, or Documents or for Proceeds of any Collateral (either in a Credit Party’s name or Administrative Agent’s or any Lender’s name, at

- 13 - Administrative Agent’s option), with the right to enforce, compromise, settle, or discharge any such amounts; and (F) on demand, require or cause all invoices and statements sent to any Account Debtor to state that the Accounts and such other obligations have been assigned to Administrative Agent and are payable directly and only to Administrative Agent and Credit Parties shall deliver to Administrative Agent such originals of documents evidencing the sale and delivery of Goods or the performance of services giving rise to any Accounts as Administrative Agent may require; and (ii) exercise such other rights and remedies which may be available to it under this Agreement, the other Loan Documents, and agreements relating to Bank Products, and Applicable Law (including all rights of a secured party under Article 9 of the UCC), all of which shall be cumulative. (b) Administrative Agent shall not be liable or responsible in any way for the safekeeping of any Collateral, for any loss or damage thereto while Collateral is in Administrative Agent’s (or its designee’s) possession or control (including Article 9 Control), for any diminution in the value thereof, or for any act or default of any warehouseman, carrier, forwarding agency, or other Person whatsoever, and all of the same shall be at Credit Parties’ sole risk. (c) Each Credit Party hereby acknowledges that the Obligations arise out of a commercial transaction, and agrees that if an Event of Default shall occur and be continuing Administrative Agent shall have the right to an immediate writ of possession of any Collateral on an ex parte basis and without notice of a hearing. Section 16. Commercially Reasonable Sale. Each Credit Party agrees that notice of any proposed sale or other disposition of Collateral by Administrative Agent conducted pursuant to Section 15 hereof shall be deemed to be “commercially reasonable” if such notice is delivered as provided in Section 15.1 of the Credit Agreement at least ten (10) days before the action to be taken, and Credit Parties waive any other notice in regard thereto. Administrative Agent shall have the right to conduct such sales or other dispositions of Collateral on any Credit Party’s premises, without charge, and such sales or other dispositions may be adjourned by Administrative Agent from time to time in accordance with Applicable Law. Administrative Agent (acting individually or through its designee) may purchase any Collateral at any public sale or, if permitted by Applicable Law, at any private sale and, in lieu of actual full payment of the purchase price, may set off the amount of such price against all or such portion of the Obligations as Administrative Agent may elect. Each Credit Party shall be liable for any deficiencies, with interest at the highest interest rate provided for in the Credit Agreement in regard thereto (including interest arising after commencement any Credit Party’s Insolvency Proceeding, whether or not such interest is allowed in such Insolvency Proceeding) and all costs and expenses of collection and enforcement, including attorneys’ fees and expenses, if the Proceeds of the disposition of the Collateral do not result in Payment in Full of all Obligations. To the extent that Applicable Law imposes any duties on Administrative Agent to exercise remedies in a “commercially reasonable” manner which duties cannot be waived under Applicable Law(provided that, for the avoidance of any doubt, to the extent that any such duties that can be waived under Applicable Law the foregoing are hereby waived by each of the Credit Parties), each Credit Party acknowledges and agrees that it is not commercially unreasonable for Administrative Agent (a) to fail to obtain third party consents for access to Collateral to be disposed of, or to obtain or, if not required by Applicable Law, to fail to obtain consents of any Governmental Authority or other third party for the collection or disposition of Collateral to be collected or disposed of; (b) to fail to exercise collection remedies against Account Debtors, secondary obligors or other Persons obligated on Collateral or to remove Liens on or any adverse claims against, Collateral; (c) to exercise collection remedies against Account Debtors and other Persons obligated on Collateral directly or through the use of collection agencies and other collection specialists; (d) to advertise dispositions of Collateral through publications or media of general circulation, whether or not the Collateral is of a specialized nature; (e) to contact other Persons, whether or not in the same business as any Credit Party, for expressions of interest in acquiring all or any

- 14 - portion of the Collateral; (f) to hire one or more professional auctioneers to assist in the disposition of Collateral, whether or not the Collateral is of a specialized nature; (g) to dispose of Collateral by utilizing Internet sites that provide for the auction of assets of the types included in the Collateral or that have the reasonable capability of doing so or that match buyers and sellers of assets; (h) to dispose of assets in wholesale rather than retail markets; (i) to disclaim disposition and other warranties; (j) to purchase, at Credit Parties’ expense, insurance or credit enhancements to insure Administrative Agent against risks of loss, collection, or disposition of Collateral or to provide to Administrative Agent and the other Secured Parties a guaranteed return from the collection or disposition of Collateral; or (k) to obtain the services of other brokers, investment bankers, consultants, and other professionals to assist Administrative Agent in the collection or disposition of any of the Collateral. Each Credit Party further agrees that any sale of Collateral to a Licensor pursuant to the terms of a License is sufficient to constitute a commercially reasonable sale (including as to method, terms, manner, and time). Each Credit Party acknowledges that the purpose of this Section is to provide non-exhaustive indications of what actions or omissions by Administrative Agent would not be commercially unreasonable in the exercise by Administrative Agent of rights and remedies against the Collateral and that other actions or omissions by Administrative Agent shall not be deemed to be commercially unreasonable solely on account of not being expressly indicated in this Section. Without limitation of the foregoing, nothing contained in this Section shall be construed to grant any rights to any Credit Party or to impose any duties on Administrative Agent that would not have been granted or imposed by this Agreement, any other Loan Document, any agreement related to Bank Products, or by Applicable Law in the absence of this Section. Section 17. Miscellaneous; Governing Law; Submission to Jurisdiction. All terms of Section 15 of the Credit Agreement (Miscellaneous), as such Section 15 is in effect on the Closing Date, and as it may be modified or amended from time to time hereafter in accordance with Section 15.2 thereof, are herewith incorporated by reference into this Agreement and made an integral part hereof, as fully and completely as if set forth verbatim herein, with specific respect to this Agreement, such that each reference therein to “this Agreement” (and words of similar import) in said Section 15 shall mean and refer, for purposes hereof, to this Agreement, mutatis mutandis, unless and except to the extent otherwise expressly provided herein.

WITH RESPECT TO SUCH COURTS, EACH CREDIT PARTY IRREVOCABLY WAIVES ALL CLAIMS, OBJECTIONS, AND DEFENSES THAT IT MAY HAVE REGARDING PERSONAL OR SUBJECT MATTER JURISDICTION, VENUE, OR INCONVENIENT FORUM. EACH PARTY HERETO WAIVES PERSONAL SERVICE OF PROCESS OF ANY AND ALL PROCESS SERVED UPON IT AND IRREVOCABLY CONSENTS TO SERVICE OF PROCESS IN THE MANNER PROVIDED FOR THE GIVING OF NOTICES GENERALLY IN SECTION 15.1 OF THE credit agreement, SUCH SERVICE TO BE EFFECTIVE AT THE TIME SUCH NOTICE WOULD

- 15 - BE DEEMED DELIVERED UNDER SECTION 15.1 OF THE CREDIT AGREEMENT. NOTHING HEREIN SHALL LIMIT THE RIGHT OF ADMINISTRATIVE AGENT, OR ANY LENDER TO BRING PROCEEDINGS AGAINST ANY CREDIT PARTY IN ANY OTHER COURT OR JURISDICTION, NOR LIMIT THE RIGHT OF ADMINISTRATIVE AGENT OR ANY LENDER TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY APPLICABLE LAW. NOTHING IN THIS AGREEMENT SHALL BE DEEMED TO PRECLUDE ENFORCEMENT BY ADMINISTRATIVE AGENT OF ANY JUDGMENT OR ORDER OBTAINED IN ANY FORUM OR JURISDICTION. NOTHING CONTAINED HEREIN SHALL LIMIT THE RIGHT OF ADMINISTRATIVE AGENT OR ANY LENDER TO BRING PROCEEDINGS (INCLUDING ENFORCEMENT OF ANY JUDGMENT OR ORDER) AGAINST ANY CREDIT PARTY IN ANY OTHER JURISDICTION OR LIMIT THE RIGHT OF ANY SUCH PERSON TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY APPLICABLE LAW.
