(h)    Upon the occurrence and during the continuance of an Event of Default, the Administrative Agent shall have the right at any time to give notice of the security interest created hereby to account debtors obligated to any Grantor and to take over and direct collection of the Accounts, the Chattel Paper and the Electronic Chattel Paper, to notify such account debtors to make payment directly to the Administrative Agent, to enforce payment of the Accounts, the Chattel Paper and the Electronic Chattel Paper and to enforce such Grantor's contract rights.

(l)    Each Grantor shall at any time and from time to time, take such commercially reasonable steps as the Administrative Agent may reasonably request (i) to cause any bailee having possession of any of the Collateral with a value in excess of Five Hundred Thousand and 00/100 Dollars ($500,000.00) or any landlord of such Grantor’s leased real property locations where Collateral with a value in excess of Five Hundred Thousand and 00/100 Dollars ($500,000.00) is located to provide to the Administrative Agent a written acknowledgement of the Lenders' security interest in such Collateral, in form and substance satisfactory to the Administrative Agent, (ii) to cause the Administrative Agent to obtain "control" of any Investment Property, Deposit Accounts, Letter-of-Credit Rights or Electronic Chattel Paper including, but not limited to, causing any issuer of a letter of credit with respect to the Letter-of-Credit Rights to consent to the Lenders' security interest therein and including an appropriate legend on Chattel Paper arising from the sale of Inventory identifying the Lenders' security interest therein, and (iii) otherwise to ensure the Lenders' security interest in any of the Collateral is a Prior Security Interest.

(ix)    Sign the name of such Grantor to verifications of Accounts and notices of Accounts sent by account debtors to such Grantor; or

(x)    Take all other actions necessary or desirable to protect such Grantor's interest(s) in the Accounts.

Each Grantor ratifies and approves all acts of said attorneys and agrees that said attorneys shall not be liable for any acts of commission or omission, nor for any error of judgment or mistake of fact or law, other than liability arising under the Code and to the extent caused by gross negligence or willful misconduct of said attorneys as determined by a final non-appealable judgment of a court of competent jurisdiction. This power, being coupled with an interest, is irrevocable until the Obligations are Paid in Full. Each Grantor further agrees to assist the Administrative Agent in the collection and enforcement of the Accounts and will not hinder, delay or impede the Administrative Agent in any manner in its collection and enforcement of the Accounts.

Section 6.    Preservation and Protection of Security Interest. Each Grantor represents and warrants that it has (or will have upon its acquisition of such Collateral), and covenants and agrees that at all times during the term of this Security Agreement it will have, good and valid title to the Collateral from time to time owned or acquired by it free and clear of all Liens, except Permitted Liens, and shall defend the Collateral against the claims and demands of all Persons whomsoever other than the holders of any Permitted Liens. Each Grantor covenants and agrees that it shall not (i) borrow against the Collateral or any portion of the Collateral from any other Person except as may otherwise be permitted under the Credit Agreement or (ii) grant or create or permit to attach or exist any Lien on, of or in any of the Collateral or any portion of the Collateral except Permitted Liens. Each Grantor shall faithfully preserve and protect the Lenders' security interest in the Collateral and shall, at its own cost and expense, cause or assist the Administrative Agent to cause that security interest to be perfected and continue perfected so long as the Obligations or any portion of the Obligations are outstanding, unpaid or executory. For purposes of the perfection of the Lenders' security interest in the Collateral in accordance with the requirements of this Security Agreement, each Grantor authorizes the Administrative Agent, at any time and from time to time, to file financing statements, continuation statements and amendments thereto that describe the Collateral as all assets of such Grantor or words of similar effect and which contain any other information required by the Code for the sufficiency or filing office acceptance of any financing statement, continuation statement or amendment. If any such financing statement, continuation statement or amendment requires the signature of such Grantor, it may be signed by the Administrative Agent on behalf of such Grantor. Each Grantor shall from time to time at the request of the Administrative Agent file or record, or cause to be filed or recorded, such other instruments, documents and notices, including financing statements, assignments and certificates of title, as the Administrative Agent may reasonably deem necessary or advisable from time to time in order to perfect and continue perfected such security interest. Each Grantor shall do all such other acts and things, shall execute and deliver all such other instruments and documents, including further security agreements, control agreements, pledges, endorsements, assignments, certificates of title and notices, and shall furnish any other information as the Administrative Agent, in its reasonable discretion, may deem necessary or advisable from time to time in order to perfect and preserve the priority of such security interest as a Prior Security Interest. Notwithstanding anything to the contrary contained herein, unless an Event of Default has occurred and is continuing and the Administrative Agent has requested the Grantors to do so, the Grantors shall not be required to cause or assist the Administrative Agent to perfect any security interest in any Collateral consisting of goods subject to a certificate of title. Each Grantor irrevocably appoints the Administrative Agent (and any of the Administrative Agent's designated officers, employees and/or agents) as the attorney-in-fact of the Grantor to take such action as the Administrative Agent may deem necessary from time to time to preserve, perfect and continue perfected the Lenders' security interest in the Collateral in accordance with the requirements of this Security Agreement including, but not limited to, signing any certificates of title, financing statements or amendments to financing statements evidencing the Administrative Agent's security interest in the Collateral for and on behalf of such Grantor. Each Grantor agrees that a carbon, photographic or other reproduction of this Security Agreement or financing statement is sufficient as a financing statement and may be filed instead of the original. Each Grantor hereby ratifies any and all financing statements and amendments to financing statements evidencing the Administrative Agent's security interest in the Collateral filed prior to the date hereof.

Section 7.    Insurance. Risk of loss of, damage to, or destruction of the Equipment and Inventory is on the Grantors. The Grantors shall insure the Equipment and Inventory against such risks and casualties and in such amounts and with such insurance companies as is set forth in the Credit Agreement. If the Grantors fail to effect and keep in full force and effect such insurance, or fail to pay the premiums when due, the Administrative Agent may (but shall not be obligated to) do so for the account of the Grantors and add the cost thereof to the Obligations. Subject to the terms and conditions of the Credit Agreement, (i) each Grantor assigns and sets over to the Administrative Agent all monies which may become payable on account of such insurance and directs the insurers to pay the Administrative Agent any amount so due, (ii) the Administrative Agent is irrevocably appointed attorney‑in‑fact of each Grantor to endorse any draft or check that may be payable to such Grantor in order to collect the proceeds of such insurance and (iii) any balance of insurance proceeds remaining in the possession of the Administrative Agent after Payment In Full shall be paid over to such Grantor or its order.

Section 8.    Maintenance and Repair; Control. If any Grantor fails to maintain the Equipment and Inventory in accordance with the terms of the Credit Agreement, the Administrative Agent may (but shall not be obligated to) pay the cost of such repairs or maintenance and such taxes, levies or impositions for the account of such Grantor and add the amount of such payments to the Obligations.

Section 9.    Preservation of Rights Against Third Parties; Preservation of Collateral in the Administrative Agent's Possession. Until such time as the Administrative Agent exercises its right during the continuance of an Event of Default to effect direct collection of the Accounts, the Chattel Paper and the Electronic Chattel Paper and to effect the enforcement of the Grantors' contract rights, each Grantor shall take any and all steps necessary to preserve their rights in respect of the Accounts, the Chattel Paper and the Electronic Chattel Paper and their contracts against third parties. The Administrative Agent shall be deemed to have exercised reasonable care in the custody and preservation of such of the Collateral as may come into its possession from time to time if the Administrative Agent takes such action for that purpose as each Grantor shall request in writing, provided that such requested action shall not, in the judgment of the Administrative Agent, impair the security interest of the Administrative Agent and the Lenders in the Collateral or their rights in, or the value of, the Collateral, and provided further that the Administrative Agent receives such written request in sufficient time to permit the Administrative Agent to take the requested action.

Section 10.    Events of Default and Remedies.

(a)    Upon the occurrence and during the continuance of an Event of Default, the Administrative Agent may then in any way permitted by Law foreclose the Lien in the Collateral granted hereby including, without limitation, upon ten (10) days prior written notice to the Grantors, Administrative Agent may sell any or all Collateral at private sale at any time or place in one or more sales, at such price or prices and upon such terms, either for cash or on credit, as the Administrative Agent and the Lenders, in their sole discretion, may elect, or sell any or all Collateral at public auction, either for cash or on credit, as the Administrative Agent and the Lenders, in their sole discretion, may elect, and at any such sale, the Administrative Agent may bid for and become the purchaser of any or all such Collateral. Pending any such action, the Administrative Agent may liquidate the Collateral.

(b)    Upon the occurrence and during the continuance of an Event of Default, the Administrative Agent may then grant extensions to or adjust claims of, or make compromises or settlements with, debtors, the Grantors or any other Persons with respect to the Collateral or any securities, guarantees or insurance applying thereon, without notice to or the consent of any Grantor, without affecting the Grantor's liability under this Security Agreement, the Credit Agreement or the other Loan Documents. Each Grantor waives notice of acceptance, of nonpayment, protest or notice of protest of any Accounts, Chattel Paper or Electronic Chattel Paper or any of its contract rights and any other notices to which the Grantor may be entitled.

(c)    Upon the occurrence and during the continuance of an Event of Default, then in any such event, the Administrative Agent and the Lenders shall have such additional rights and remedies in respect of the Collateral or any portion thereof as are provided by the Code (whether or not the Code applies to the affected Collateral) and such other rights and remedies in respect thereof which they may have at Law or in equity or under the Loan Documents including, without limitation, the right to enter any premises where Equipment and/or Inventory are located and take possession and control thereof without demand or notice and without prior judicial hearing or legal proceedings, which each Grantor expressly waives.

(d)    Upon the occurrence and during the continuance of an Event of Default, the Grantors shall promptly, following demand by the Administrative Agent, assemble the Equipment and Inventory and make them available to the Administrative Agent at a place or places reasonably designated by the Administrative Agent. The right of the Administrative Agent under this paragraph to have the Equipment and Inventory assembled and made available to it is of the essence of this Security Agreement and the Administrative Agent may, at its election, enforce such right by an action in equity for injunctive relief or specific performance.

(e)    Upon the occurrence and during the continuance of an Event of Default, then in any event, the Administrative Agent shall have the right to use and operate under all trade names under which each Grantor does business.

Section 11.    Continuing Validity of Obligations. Until the earlier of the Release Date or Payment In Full, the agreements and obligations of the Grantors hereunder are continuing agreements and obligations, and are absolute and unconditional irrespective of the genuineness, validity or enforceability of the Credit Agreement, the Notes or any other instrument or instruments now or hereafter evidencing the Obligations or any part thereof or of the Loan Documents or any other agreement or agreements now or hereafter entered into by the Administrative Agent or any Lender and any Grantor pursuant to which the Obligations or any part thereof is issued or of any other circumstance which might otherwise constitute a legal or equitable discharge of such agreements and obligations. Without limitation upon the foregoing, such agreements and obligations of a Grantor hereunder shall continue in full force and effect as long as the Obligations or any part thereof remain outstanding and unpaid and shall remain in full force and effect without regard to and shall not be released, discharged or in any way affected by (i) any renewal, refinancing or refunding of the Obligations in whole or in part, (ii) any extension of the time of payment of the Notes or other instrument or instruments now or hereafter evidencing the Obligations, or any part thereof, (iii) any compromise or settlement with respect to the Obligations or any part thereof, or any forbearance or indulgence extended to any Grantor, (iv) any amendment to or modification of the terms of the Notes or other instrument or instruments now or hereafter evidencing the Obligations or any part thereof or any other agreement or agreements now or hereafter entered into by the Administrative Agent or any Lender and any Grantor pursuant to which the Obligations or any part thereof is issued or secured, (v) any substitution, exchange, or release of a portion of, or failure to preserve, perfect or protect, or other dealing in respect of, any of the Collateral or any other property or any security for the payment of the Obligations or any part thereof, (vi) any bankruptcy, insolvency, arrangement, composition, assignment for the benefit of creditors or similar proceeding commenced by or against any Grantor, (vii) any dissolution, liquidation or termination of any Grantor for any reason whatsoever or (viii) any other matter or thing whatsoever whereby the agreements and obligations of the Grantors hereunder, would or might otherwise be released or discharged, in whole or in part. Each Grantor hereby waives notice of the acceptance of this Security Agreement by the Administrative Agent.

Section 12.    Defeasance. Notwithstanding anything to the contrary contained in this Security Agreement, upon the earlier of the Release Date or Payment In Full, this Security Agreement shall terminate and be of no further force and effect and at the request of the Grantors, the Administrative Agent shall thereupon terminate the Lenders' security interest in the Collateral and promptly file requested releases and/or termination statements with respect to the Collateral. Until such time, however, this Security Agreement shall be binding upon and inure to the benefit of the parties, their respective successors and assigns, provided that the Grantors may not assign this Security Agreement or any of their rights under this Security Agreement or delegate any of their duties or obligations under this Security Agreement and any such attempted assignment or delegation shall be null and void. This Security Agreement is not intended and shall not be construed to obligate the Administrative Agent to take any action whatsoever with respect to the Collateral or to incur expenses or perform or discharge any obligation, duty or disability of the Grantors.

Section 13.    Joinder. Upon the execution and delivery by any other Person of a Guarantor Joinder that occurs prior to the Release Date, (i) such Person shall become a "Grantor" hereunder with the same force and effect as if it were originally a party to this Security Agreement and named as a "Grantor" on the signature pages hereto and (ii) the Exhibits to this Security Agreement shall be deemed updated by the supplemental Exhibits to this Security Agreement delivered pursuant to the terms of such Guarantor Joinder. The execution and delivery of any such Guarantor Joinder shall not require the consent of any other Grantor hereunder, and the rights and obligations of each Grantor hereunder shall remain in full force and effect notwithstanding the addition of any new Grantor as a party to this Security Agreement.

Section 14.    Miscellaneous.

If any provision of this Security Agreement shall for any reason be held invalid or unenforceable, in whole or in part, in any jurisdiction, such provision shall, as to such jurisdiction, be ineffective only to the extent of such invalidity or unenforceability without in any manner affecting the validity or enforceability of such provision in any other jurisdiction or any other provision of this Security Agreement in any jurisdiction.
