The $500,000 threshold described in clause (iii)(A) of the preceding sentence as it relates to any deposit account shall be measured by reference to the closing balance of such deposit account as of each Business Day.

such Grantor of any material property for which additional filings or recordings are necessary to perfect and maintain the Collateral Agent’s security interest therein (to the extent perfection of the security interest in such property is required hereby or by the terms of the Indenture). Each Grantor agrees not to effect or permit any change referred to in the preceding sentence unless all filings are promptly made under the Uniform Commercial Code or other applicable law that are required in order for the Collateral Agent to continue at all times following such change to have a valid, legal and perfected, security interest (subject to the terms of each Intercreditor Agreement (if any) and subject to Permitted Liens) in the Collateral for its benefit and the benefit of the other Secured Parties.

(e) Change in Location of Collateral. No Grantor shall (i) maintain any Collateral with a Fair Market Value in excess of $2,500,000 (other than Inventory in transit, consignments of Inventory not in excess of $2,500,000, rolling stock, equipment in transit between locations set forth in Exhibit A, equipment at other locations for purposes of maintenance or repair and Collateral in the Collateral Agent’s possession or the possession of any ABL Collateral Agent) at any location other than those locations listed on Exhibit A, (ii) otherwise change or add to any of such locations, or (iii) change the location of its jurisdiction of organization from the location identified in Exhibit A, unless in each case it gives the Collateral Agent prompt written notice thereof but in any event described in clause (iii) not later than 30 days prior thereto, and executes or authorizes the filing of any and all financing statements and other documents that are necessary or that the Collateral Agent reasonably requests in connection therewith. In the event any Grantor changes or adds any location of Collateral, such Grantor shall prepare and promptly deliver to the Collateral Agent a revised Exhibit A, which shall automatically be adopted as Exhibit A for all purposes. Each Grantor agrees not to effect or permit any change referred to in the preceding sentences unless all filings are promptly made under the Uniform Commercial Code or other applicable law that are required in order for the Collateral Agent to continue at all times following such change to have a valid, legal and perfected security interest (subject to the terms of each Intercreditor Agreement (if any) and subject to Permitted Liens) in the Collateral for its benefit and the benefit of the other Secured Parties.

Section 4.2 Perfection and Protection of Security Interest.

(a) Perfection and Protection.

To the extent permitted by any Requirement of Law and each Intercreditor Agreement (if any), the Collateral Agent may file, without any Grantor’s signature, one or more financing statements disclosing the Collateral Agent’s Liens. Each Grantor hereby authorizes the Collateral Agent to attach each Amendment to this Agreement and agrees that all additional collateral set forth in such Amendments shall be considered to be part of the Collateral.

(b) Collateral in Other’s Possession. If at any time any Collateral with a Fair Market Value in excess of $2,500,000 (other than ABL First Lien Collateral, unless (i) no Senior Liens on such Collateral are outstanding or (ii) the applicable ABL Collateral Agent shall also have obtained such waiver or subordination from such landlord) is located at any operating facility of a Grantor which is not owned by such Grantor, such Grantor shall, upon request, use commercially reasonable efforts to obtain written landlord lien waivers or subordinations, in form and substance reasonably satisfactory to the Collateral Agent, of all present and future Liens to which the owner or lessor of such premises may be entitled to assert against such Collateral.

(c) Confirmatory Instruments. From time to time, subject to each Intercreditor Agreement (if any), each Grantor shall, upon the Collateral Agent’s request, execute and deliver confirmatory written instruments pledging to the Collateral Agent, for the benefit of the Secured Parties, the Collateral with respect to such Grantor, but the failure to do so shall not affect or limit any security interest or any other rights of the Secured Parties in and to the Collateral with respect to such Grantor.

Section 4.3 Electronic Chattel Paper. If any Grantor at any time holds or acquires an interest in any Electronic Chattel Paper or any “transferable record”, as that term is defined in Section 201 of the Federal Electronic Signatures in Global and National Commerce Act, or in Section 16 of the Uniform Electronic Transactions Act as in effect in any relevant jurisdiction, such Grantor shall promptly notify the Collateral Agent thereof and (other than if such Electronic Chattel Paper constitutes ABL First Lien Collateral for which Senior Liens are outstanding) shall take such action as is necessary to vest in the Collateral Agent Control under UCC Section 9-105 of such Electronic Chattel Paper or control (to the extent the meaning of “control” has not been clearly established under such provisions, “control” in this paragraph (d) to have such meaning as the Collateral Agent shall reasonably specify in writing after

consultation with the Issuer) under Section 201 of the Federal Electronic Signatures in Global and National Commerce Act or, as the case may be, Section 16 of the Uniform Electronic Transactions Act, as so in effect in such jurisdiction, of such transferable record. The Collateral Agent agrees with such Grantor that the Collateral Agent will arrange, pursuant to procedures reasonably satisfactory to the Collateral Agent and so long as such procedures will not result in the Collateral Agent’s loss of Control or control, as applicable, which may be established to the satisfaction of the Collateral Agent pursuant to the delivery to it by the Grantor of an Officers’ Certificate or an Opinion of Counsel, for the Grantor to make alterations to the Electronic Chattel Paper or transferable record permitted under UCC Section 9-105 or, as the case may be, Section 201 of the Federal Electronic Signatures in Global and National Commerce Act or Section 16 of the Uniform Electronic Transactions Act for a party in Control to allow without loss of Control or control, as applicable, unless an Event of Default has occurred and is continuing or would occur after taking into account any action by such Grantor with respect to such Electronic Chattel Paper or transferable record.

Section 4.4 Maintenance of Property. Except as otherwise permitted hereunder or pursuant to the Indenture Documents, each Grantor shall maintain all of its property necessary and useful in the conduct of its business, in reasonable operating condition and repair, ordinary wear and tear excepted.

Each Grantor will promptly give to the Collateral Agent copies of any material notices or other material communications received by it with respect to any Investment Property Collateral registered in the name of such Grantor (provided, that if such Investment Property Collateral constitutes ABL First Lien Collateral only so long as no Senior Liens are outstanding on such Collateral). Following the occurrence and during the continuance of an Event of Default, the Collateral Agent shall at all times have the right to exchange the certificates representing Investment Property Collateral for certificates of smaller or larger denominations for any purpose consistent with this Agreement (provided, that if such Investment Property Collateral constitutes ABL First Lien Collateral only so long as no Senior Liens are outstanding on such Collateral).

(b) Voting Rights, Distributions, Etc. in Respect of Investment Property Collateral.

(i) Unless an Event of Default exists and subject to each Intercreditor Agreement (if any), (A) each Grantor shall be entitled to exercise any and all voting and other consensual rights (including, the right to give consents, waivers, and notifications in respect of any securities) pertaining to its Investment Property Collateral or any part thereof; provided, however, that without the prior written consent of the Collateral Agent and the Trustee obtained in accordance with the Indenture (provided, that if such

Investment Property Collateral constitutes ABL First Lien Collateral only so long as no Senior Liens are outstanding on such Collateral), no vote shall be cast or consent, waiver, or ratification given or action taken which would amend, modify, or waive any term, provision, or condition of the certificate of incorporation, bylaws, certificate of formation, or other charter document or other agreement relating to, evidencing or providing for the issuance of any such Investment Property Collateral, in any manner that would materially impair such Investment Property Collateral, the transferability thereof, or the Collateral Agent’s Liens therein, and (B) each Grantor shall be entitled to receive and retain any and all dividends, interest paid and other cash distributions in respect of any of such Investment Property Collateral (unless otherwise required by the Indenture).

(ii) During the existence of an Event of Default, subject to each Intercreditor Agreement (if any) and the rights of any applicable ABL Collateral Agent and any ABL Secured Parties thereunder, (A) the Collateral Agent may, after delivery of notice to the applicable Grantor, exercise all voting and corporate rights at any meeting of any corporation, partnership, or other business entity issuing any of the Investment Property Collateral and the proceeds thereof (in cash or otherwise) held by the Collateral Agent hereunder, and any and all rights of conversion, exchange, subscription, or any other rights, privileges, or options pertaining to any of the Investment Property Collateral as if it were the absolute owner thereof, including, the right to exchange at its discretion any and all of the Investment Property Collateral upon the merger, consolidation, reorganization, recapitalization, or other readjustment of any Investment Property Issuer or upon the exercise by any such issuer or the Collateral Agent of any right, privilege, or option pertaining to any of the Investment Property Collateral, and in connection therewith, to deposit and deliver any and all of the Investment Property Collateral with any committee, depositary, transfer agent, registrar, or other designated agency upon such terms and conditions as it may determine, all without liability except to account for property actually received by it, but the Collateral Agent shall have no duty to exercise any of the aforesaid rights, privileges, or options, and the Collateral Agent shall not be responsible for any failure to do so or delay in so doing, (B) all rights of any Grantor to exercise the voting and other consensual rights which it would otherwise be entitled to exercise pursuant to Section 4.5(b)(i) and to receive the dividends, interest, and other distributions which it would otherwise be authorized to receive and retain thereunder shall be suspended until such Event of Default shall no longer exist or as the Collateral Agent shall otherwise specify, and all such rights shall, until such Event of Default shall no longer exist or as the Collateral Agent shall otherwise specify, thereupon become vested in the Collateral Agent which shall thereupon have the sole right, but no duty, to exercise such voting and other consensual rights and to receive and hold as Investment Property Collateral such dividends, interest, and other distributions, (C) all dividends, interest, and other distributions which are received by any Grantor contrary to the provisions of this Section 4.5(b)(ii) shall be received in trust for the benefit of the Collateral Agent, shall be segregated from other funds of such Grantor and shall be forthwith paid over to the Collateral Agent as Collateral in the same form as so received (with any necessary endorsement), and (D) each Grantor shall execute and deliver (or cause to be executed and delivered) to the Collateral Agent all such proxies and other instruments as the Collateral Agent may reasonably request for the purpose of enabling the Collateral Agent to exercise the voting and other rights which it is entitled to exercise

pursuant to this Section 4.5(b)(ii) and to receive the dividends, interest, and other distributions which it is entitled to receive and retain pursuant to this Section 4.5(b)(ii). The foregoing shall not in any way limit the Collateral Agent’s power and authority granted pursuant to Section 7.4. After all Events of Default have been cured or waived and the applicable Grantor shall have delivered to the Collateral Agent certificates to that effect, the Collateral Agent shall, promptly after all such Events of Default have been cured or waived, repay to each Grantor (without interest) all dividends or other distributions that such Grantor would otherwise be permitted to retain pursuant to the terms of Section 4.5(b)(i) above and that remain in such account.

(c) The Grantors will cause or permit the Collateral Agent from time to time to cause the appropriate Investment Property Issuers (and, if held with a securities intermediary, such securities intermediary) of uncertificated securities or other types of Investment Property Collateral not represented by certificates to ▇▇▇▇ their books and records with the numbers and face amounts of all such uncertificated securities or other types of Investment Property Collateral not represented by certificates and all rollovers and replacements therefor to reflect the Lien of the Collateral Agent granted pursuant to this Agreement. The Grantors will take any actions reasonably necessary to cause (a) the Investment Property Issuers of uncertificated securities which are Investment Property Collateral, and (b) any securities intermediary which is the holder of any Investment Property Collateral, to cause the Collateral Agent to have and retain Control over such Investment Property Collateral.

Section 4.6 Proprietary Rights.

Section 4.7 Inventory. Each Grantor shall keep its Inventory (other than returned or obsolete Inventory) in good and marketable condition, except for damaged or defective goods arising in the ordinary course of such Grantor’s business.

Section 4.8 Commercial Tort Claims. If any Grantor shall at any time, acquire a Commercial Tort Claim, the recovery from which could reasonably be expected to exceed $500,000, such Grantor shall promptly notify the Collateral Agent thereof in a writing, therein providing a reasonable description and summary thereof, and upon delivery thereof to the Collateral Agent, together with an Amendment as contemplated by Section 4.2(a)(iii), such Grantor shall be deemed thereby to grant to the Collateral Agent a security interest in such Commercial Tort Claim (subject to each Intercreditor Agreement (if any)).

Section 4.9 No Interference. Each Grantor agrees that it will not interfere with any right, power and remedy of the Collateral Agent provided for in this Agreement or now or hereafter existing at law or in equity or by statute or otherwise, or the exercise or beginning of the exercise by the Collateral Agent of any one or more of such rights, powers or remedies.

Certificates of insurance of the policies shall be delivered to the Collateral Agent if requested.

(c) The Issuer shall promptly provide written notice to the Collateral Agent of any loss, damage, or destruction to the Collateral in excess of (A) $1,500,000 if covered by insurance or (B) $500,000 if not covered by insurance. During the existence of an Event of Default, subject to each Intercreditor Agreement (if any) and the rights of any applicable ABL Collateral Agent and any ABL Secured Parties thereunder, the Collateral Agent is hereby authorized to directly collect all insurance proceeds in respect of Collateral and to apply such proceeds in accordance with Section 5.3.

(d) Unless the Grantors provide the Collateral Agent with evidence of the insurance coverage on the Collateral required by this Section 4.10, subject to each Intercreditor Agreement (if any), the Collateral Agent may, upon sixty (60) days’ prior notice, purchase insurance at the applicable Grantor’s expense to protect the Collateral Agent’s Lien on such Collateral owned by the applicable Grantor. This insurance may, but need not, protect the interests of the Grantors. The coverage that the Collateral Agent purchases may (but shall not be required to) pay any claim that the Grantors make or any claim that is made against the Grantors in connection with said Collateral. The Grantors may later cancel any insurance purchased by the Collateral Agent but only after providing the Collateral Agent with evidence that the Grantors have obtained insurance as required by this Agreement. If the Collateral Agent purchases such insurance, the applicable Grantor will be responsible for the costs of that insurance, including interest and any other reasonable charges the Collateral Agent may impose in connection with the placement of insurance, until the effective date of the cancellation or expiration of the insurance. The costs of the insurance shall be added to the Obligations. The costs of the insurance may be more than the cost of insurance that the Grantors may be able to obtain on their own.

Section 4.11 Condemnation. Subject to each Intercreditor Agreement (if any) and the rights of any applicable ABL Collateral Agent and any ABL Secured Parties thereunder, each Grantor shall, promptly upon learning of the institution of any proceeding for the condemnation or other taking of any of its property with a Fair Market Value in excess of $500,000, notify the Collateral Agent of the pendency of such proceeding.

reasonably request to carry out the terms and conditions of this Agreement and the other Indenture Documents. Upon the acquisition by any Grantor of any After-Acquired Property (but subject to the limitations, if applicable, set forth herein, in the Indenture or in each Intercreditor Agreement (if any)), such Grantor shall execute and deliver such security instruments, financing statements and certificates and opinions of counsel as shall be reasonably necessary to vest in the Collateral Agent a perfected security interest or other Lien in such After-Acquired Property and to have such After-Acquired Property added to the Collateral and shall promptly deliver such Officers’ Certificates and Opinions of Counsel as are customary in secured financing transactions in the relevant jurisdiction(s) or as are reasonably requested by the Trustee or the Collateral Agent (subject to customary assumptions, exceptions and qualifications), and thereupon all provisions of this Agreement relating to the Collateral, shall be deemed to relate to such After-Acquired Property to the same extent and with the same force and effect. If any property or assets of the Issuer or any Grantor originally deemed to be an Excluded Asset at any point ceases to be an Excluded Asset pursuant to such defined term, all or the applicable portion of such property and assets shall be deemed to be After-Acquired Property and shall be added to the Notes Collateral in accordance with the Indenture and this Agreement and each Intercreditor Agreement (if any). Subject to each Intercreditor Agreement (if any), such security interests and Liens will be created under security agreements and other instruments and documents in form reasonably satisfactory to the Collateral Agent, and the Grantors shall deliver or cause to be delivered to the Collateral Agent and the Trustee all such instruments and documents (including legal opinions, Officers’ Certificates, title insurance policies and lien searches) as are necessary or that the Collateral Agent shall reasonably request to evidence compliance with this Section 4.12. The Grantors shall furnish to the Collateral Agent each year at the time of delivery of the annual report required to be delivered by the Company pursuant to Section 4.02(a) of the Indenture, an Officer’s Certificate setting forth the information required pursuant to the Perfection Certificate or confirming that there has been no change in such information since the Effective Date or the date of the most recent certificate delivered pursuant to this Section 4.12.

ARTICLE V

REMEDIES

Section 5.1 Remedies.

(a) If an Event of Default has occurred and is continuing:

(i) the Collateral Agent shall have, for the benefit of the Secured Parties, in addition to all other rights of the Collateral Agent and the Trustee, the rights and remedies of a secured party under the UCC (whether or not the UCC applies to the affected Collateral) or under any other applicable law when a debtor is in default under a security agreement;

(ii) the Collateral Agent may, at any time, take possession of the Collateral and keep it on any Grantor’s premises, at no cost to the Collateral Agent, the Trustee or any other Secured Party or remove any part of it to such other place or places as the Collateral Agent may desire, or any Grantor shall, upon the Collateral Agent’s demand, at such Grantor’s cost, assemble the Collateral and make it available to the Collateral Agent at a place reasonably convenient to the Collateral Agent;

(iii) the Collateral Agent may sell and deliver any Collateral at public or private sales, for cash, upon credit, or otherwise, at such prices and upon such terms as the Collateral Agent deems advisable, in its sole discretion, and may, if the Collateral Agent deems it reasonable, postpone or adjourn any sale of the Collateral by an announcement at the time and place of sale or of such postponed or adjourned sale without giving a new notice of sale; provided, that in connection with any such sale of Collateral, the Collateral Agent shall use its reasonable commercial efforts to maintain the confidentiality of any proprietary information of the Grantors (consistent with the confidentiality obligations of the Holders of the Securities as required by the Indenture Documents).

(iv) the Collateral Agent may give notice of sole control or any other instruction under any Account Control Agreement and take any action provided therein with respect to the applicable Collateral;

(v) the Collateral Agent may, concurrently with or following written notice to the Grantors, transfer and register in its name or in the name of its nominee the whole or any part of the Investment Property Collateral, exchange certificates or instruments representing or evidencing Investment Property Collateral for certificates or instruments of smaller or larger denominations, exercise the voting and all other rights as a holder with respect thereto, collect and receive all cash dividends, interest, principal and other distributions made thereon and otherwise act with respect to the Investment Property Collateral as though the Collateral Agent was the outright owner thereof.

(b) Without in any way requiring notice to be given in the following manner, each Grantor agrees that any notice by the Collateral Agent of sale, disposition, or other intended action hereunder or in connection herewith, whether required by the UCC or otherwise, shall constitute reasonable notice to the Grantors if such notice is mailed by registered or certified mail, return receipt requested, postage prepaid, or is delivered personally against receipt, at least ten (10) Business Days prior to such action to the Grantors’ address specified in or pursuant to Section 8.1.

(c) If any Collateral is sold on terms other than payment in full at the time of sale, no credit shall be given against the Obligations until the Collateral Agent receives payment, and if the buyer defaults in payment, the Collateral Agent may resell the Collateral without further notice to any Grantor.

(d) In the event the Collateral Agent seeks to take possession of all or any portion of the Collateral by judicial process, each Grantor irrevocably waives: (i) the posting of any bond, surety, or security with respect thereto which might otherwise be required; (ii) any demand for possession prior to the commencement of any suit or action to recover the Collateral; and (iii) any requirement that the Collateral Agent retain possession and not dispose of any Collateral until after trial or final judgment.

(e) If an Event of Default occurs and is continuing, each Grantor hereby waives all rights to a hearing prior to the exercise by the Collateral Agent of the Collateral Agent’s rights to repossess the Collateral without judicial process or to replevy, attach, or levy upon the Collateral.

(f) Each Grantor acknowledges and agrees that the Collateral Agent has no obligation to preserve rights to the Collateral or marshal any Collateral for the benefit of any Person.

(g) Each Grantor acknowledges and agrees that the compliance by the Collateral Agent, on behalf of the Secured Parties, with any applicable state or federal law requirements may be required in connection with a disposition of the Collateral and such compliance will not be considered to adversely affect the commercial reasonableness of any sale of the Collateral.

(h) The Collateral Agent shall have the right upon any public sale or sales and, to the extent permitted by law, upon any private sale or sales, to purchase for the benefit of the Collateral Agent and the other Secured Parties, the whole or any part of the Collateral so sold, free of any right of equity redemption, which equity redemption each Grantor hereby expressly releases.

(i) Until the Collateral Agent is able to effect a sale, lease, transfer or other disposition of Collateral, the Collateral Agent shall have the right, but no duty or obligation, to hold or use Collateral, or any part thereof, to the extent that it deems appropriate for the purpose of preserving Collateral or the value of the Collateral, or for any other purpose deemed appropriate by the Collateral Agent. The Collateral Agent may, if it so elects, but shall have no obligation to, seek the appointment of a receiver or keeper to take possession of Collateral and to enforce any of the Collateral Agent’s remedies (for the benefit of the Collateral Agent and Secured Parties), with respect to such appointment without prior notice or hearing as to such appointment.

(j) Each Grantor recognizes that the Collateral Agent may be unable to effect a public sale of any or all of the Collateral consisting of securities to be sold by reason of certain prohibitions contained in the laws of any jurisdiction outside the United States or in applicable federal or state securities laws but may be compelled to resort to one or more private sales thereof to a restricted group of purchasers who will be obliged to agree, among other things, to acquire such Collateral or other property to be sold for their own account for investment and not with a view to the distribution or resale thereof. Each Grantor acknowledges and agrees that any such private sale may result in prices and other terms less favorable to the seller than if such sale were a public sale and, notwithstanding such circumstances, agrees that any such private sale shall not, by virtue thereof, be deemed to have been made in a commercially unreasonable manner. Unless required by a Requirement of Law, the Collateral Agent shall not be under any obligation to delay a sale of any of the Collateral or other property to be sold for the period of time necessary to permit the issuer of such securities to register such securities under the laws of any jurisdiction outside the United States or under any applicable federal or state securities laws, even if such issuer would agree to do so. Each Grantor further agrees to do or cause to be done, at its own cost and expense, to the extent that such Grantor may do so under Requirements of Law, all such other acts and things as may be necessary to make such sales or resales of any portion or all of the Collateral or other property to be sold valid and binding and in compliance with any and all Requirements of Law at the Grantors’ expense.

(k) Any remedy or enforcement action to be taken hereunder by the Collateral Agent with respect to the Collateral shall be at the written direction of the Majority Holders.

(l) Notwithstanding the foregoing, any rights and remedies provided in this Section 5.1 shall be subject to each Intercreditor Agreement (if any).

Section 5.2 Grant of Intellectual Property License. Effective only upon the occurrence and during the continuance of an Event of Default, for the purpose of enabling the Collateral Agent to exercise the rights and remedies under this Article V at such time as the Collateral Agent shall be lawfully entitled to exercise such rights and remedies, subject to the terms of each Intercreditor Agreement (if any), each Grantor hereby grants to the Collateral Agent a non-exclusive license or other right to use, without charge, each Grantor’s labels, patents, copyrights, name, trade secrets, trade names, trademarks, and advertising matter, or any similar property, to the extent constituting Collateral in completing production of, advertising or selling any Collateral, and, subject to the rights of any licensor or franchisor under such agreements and to the extent not in violation of such agreements, each Grantor’s rights under all licenses and all franchise agreements shall inure to the Collateral Agent’s benefit for such purpose.

Section 5.3 Application of Proceeds. Subject to each Intercreditor Agreement (if any), the Collateral Agent shall apply the proceeds of any collection, sale, foreclosure or other realization upon any Collateral, as well as any Collateral consisting of cash, as follows:

FIRST, to the payment of all reasonable costs and expenses incurred by the Collateral Agent (in its capacity as such hereunder or under the Indenture or any other Indenture Document) and the Trustee in connection with such collection, sale, foreclosure or realization or reasonable costs, expenses, claims or liabilities of the Collateral Agent or the Trustee otherwise relating to or arising in connection with this Agreement, the Indenture or any other Indenture Document or any of the Obligations, including all court costs and the reasonable fees and expenses of its agents and legal counsel, the repayment of all advances made by the Collateral Agent or the Trustee hereunder or under the Indenture or any other Indenture Document on behalf of any Grantor, any other reasonable costs or expenses incurred by the Collateral Agent or the Trustee in connection with the exercise of any remedy hereunder or under the Indenture or any other Indenture Document, and any indemnification of the Collateral Agent and the Trustee required by the terms hereunder, under the Indenture or any other Indenture Document;

SECOND, to the interest due in respect of the Obligations which such Collateral secures;

THIRD, to the remaining Obligations which such Collateral secures; and

FOURTH, to the applicable Grantors, their successors or assigns, or as a court of competent jurisdiction may otherwise direct.

Except as otherwise provided herein, the Collateral Agent shall have absolute discretion as to the time of application of any such proceeds, moneys or balances in accordance with this Agreement and each Intercreditor Agreement (if any). Upon any sale of Collateral by the Collateral Agent (including pursuant to a power of sale granted by statute or under a judicial proceeding), the receipt of the Collateral Agent or of the officer making the sale shall be a sufficient discharge to the purchaser or purchasers of the Collateral so sold and such purchaser or purchasers shall not be obligated to see to the application of any part of the purchase money paid over to the Collateral Agent or such officer or be answerable in any way for the misapplication thereof.

ARTICLE VI

Section 6.1 Reliance by Collateral Agent; Indemnity Against Liabilities, etc.

(a) Whenever in the performance of its duties under this Agreement or any other Indenture Document, the Collateral Agent shall deem it necessary or desirable that a matter be proved or established with respect to the Grantors or any other Person in connection with the taking, suffering or omitting of any action hereunder by the Collateral Agent, such matter may be conclusively deemed to be proved or established by a certificate executed by an Officer of such Person, including an Officers’ Certificate or an Opinion of Counsel, and the Collateral Agent shall have no liability with respect to any action taken, suffered or omitted in reliance thereon. The Collateral Agent may at any time solicit written confirmatory instructions, including a direction of the Trustee, any Grantor or an order of a court of competent jurisdiction as to any action that it may be requested or required to take or that it may propose to take in the performance of any of its obligations under this Agreement or any other Indenture Document and shall be fully justified in failing or refusing to act hereunder or under any Indenture Document until it shall have received such requisite instruction.

(b) The Collateral Agent shall be fully protected in relying upon any note, writing, affidavit, electronic communication, fax, resolution, statement, certificate, instrument, opinion, report, notice (including any notice of an Event of Default or of the cure or waiver thereof), request, consent, order or other paper or document or oral conversation (including, telephone conversations) which it in good faith believes to be genuine and correct and to have been signed, presented or made by the proper party. The Collateral Agent may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any notice, certificate or opinion furnished to the Collateral Agent in connection with this Agreement or any other Indenture Document and upon advice and statements of legal counsel (including counsel to the Issuer or any Grantor, independent accountants and other agents consulted by the Collateral Agent).

Section 6.2 Exercise of Remedies. The remedies of the Collateral Agent hereunder and under the other Security Documents shall include, but not be limited to, the disposition of the Collateral by foreclosure or other sale and the exercising of all remedies of a secured lender under the UCC, bankruptcy laws or similar laws of any applicable jurisdiction.

Section 6.3 Authorized Investments. Any and all funds held by the Collateral Agent in its capacity as Collateral Agent, whether pursuant to any provision hereof or of any other Security Document or otherwise, shall, to the extent reasonably practicable following receipt by the Collateral Agent from the Issuer of specific written instructions in form and substance reasonably satisfactory to the Collateral Agent delivered to the Collateral Agent at least three (3) business days prior to the proposed investment, be invested by the Collateral Agent within a reasonable time in the Cash Equivalents identified in such written instructions. Any interest earned on such funds shall be disbursed (i) during an Event of Default, in accordance with Section 5.3 and (ii) at all other times, as the Issuer shall direct. To the extent that the interest rate payable with respect to any such account varies over time, the Collateral Agent may use an average interest rate in making the interest allocations among the respective Secured Parties. In the absence of gross negligence or willful misconduct, the Collateral Agent shall not be responsible for any investment losses in respect of any funds invested in accordance with this Section 6.3. The Collateral Agent shall have no duty or obligation regarding the reinvestment of any such funds in the absence of updated written instructions from the Issuer in form and substance reasonably satisfactory to the Collateral Agent.

Section 6.4 Bankruptcy Proceedings. The following provisions shall apply during any Bankruptcy Proceeding of any Grantor:

(a) The Collateral Agent shall represent all Secured Parties in connection with all matters directly relating to the Collateral, including, any use, sale or lease of Collateral, use of cash collateral, request for relief from the automatic stay and request for adequate protection.

(b) Each Secured Party shall be free to act independently on any issue not affecting the Collateral. Each Secured Party shall give prior notice to the Collateral Agent of any such action that could materially affect the rights or interests of the Collateral Agent or the other Secured Parties to the extent that such notice is reasonably practicable. If such prior notice is not given, such Secured Party shall give prompt notice following any action taken hereunder.

(c) Any proceeds of the Collateral received by any Secured Party as a result of, or during, any Bankruptcy Proceeding will be delivered promptly to the Collateral Agent for distribution in accordance with Section 5.3.

LIABILITIES; ATTORNEY IN FACT; PROXY

Section 7.1 The Collateral Agent’s and the Trustee’s Rights, Duties, and Liabilities.

(a) The Grantors assume all responsibility and liability arising from or relating to the use, maintenance, storage, sale, collection, foreclosure, realization on, conveyance or other disposition of or involving the Collateral. The Obligations shall not be affected by any failure of any Grantor, the Collateral Agent or the Trustee to take any steps to perfect the Collateral Agent’s Liens or to collect or realize upon the Collateral, nor shall loss of or damage to the Collateral release any Grantor from any of the Obligations. Following the occurrence and

during the continuation of an Event of Default, the Collateral Agent may (but shall not be required to), and at the direction of the Trustee shall, subject to each Intercreditor Agreement (if any) and the terms of the Indenture, without notice to or consent from any Grantor ▇▇▇ upon or otherwise collect, extend the time for payment of, modify or amend the terms of, compromise or settle for cash, credit, or otherwise upon any terms, grant other indulgences, extensions, renewals, compositions, or releases, and take or omit to take any other action with respect to the Collateral, any security therefor, any agreement relating thereto, any insurance applicable thereto, or any Person liable directly or indirectly in connection with any of the foregoing, without discharging or otherwise affecting the liability of any Grantor for the Obligations or under the Indenture, any other Indenture Document or any other agreement now or hereafter existing between any Secured Party and any Grantor.

(b) It is expressly agreed by the Grantors that, anything herein to the contrary notwithstanding, each of the Grantors shall remain liable under each of its contracts and each of its licenses to observe and perform all the conditions and obligations to be observed and performed by it thereunder. The Collateral Agent and the Trustee shall not have any obligation or liability under any contract or license by reason of or arising out of this Agreement or the granting herein of a Lien thereon or the receipt by the Collateral Agent or the Trustee of any payment relating to any contract or license pursuant hereto that is applied as required herein. The Collateral Agent and the Trustee shall not be required or obligated in any manner to perform or fulfill any of the obligations of any Grantor under or pursuant to any contract or license, or to make any payment, or to make any inquiry as to the nature or the sufficiency of any payment received by it or the sufficiency of any performance by any party under any contract or license, or to present or file any claims, or to take any action to collect or enforce any performance or the payment of any amounts which may have been assigned to it or to which it may be entitled at any time or times.

Section 7.2 Right to Cure. The Collateral Agent may, (but shall not be required to) in its reasonable discretion, subject to each Intercreditor Agreement (if any), pay any reasonable amount or do any reasonable act required of any Grantor hereunder or under any other Indenture Document in order to preserve, protect, maintain, or enforce the Obligations, the Collateral or the Collateral Agent’s Liens therein, and which any Grantor fails to timely pay or do, including payment of any judgment against any Grantor, any insurance premium, any warehouse charge, any finishing or processing charge, any landlord’s or bailee’s claim, and any other Lien upon or with respect to the Collateral. All payments that the Collateral Agent makes under this Section 7.2 and all reasonable out-of-pocket costs and expenses that the Collateral Agent pays or incurs in connection with any action taken by it hereunder shall be promptly reimbursed by such Grantor. Any payment made or other action taken by the Collateral Agent under this Section 7.2 shall be without prejudice to any right to assert an Event of Default hereunder and to proceed thereafter as herein provided.

Section 7.3 Confidentiality.

(a) The Collateral Agent, in its individual capacity and as Collateral Agent, and the Trustee, in its individual capacity and as Trustee, agree and acknowledge that all information provided to the Collateral Agent or the Trustee by any Grantor may be considered to be proprietary and confidential information (“Confidential Information”). The Trustee and the

Collateral Agent each agrees to take all reasonable precautions necessary to keep such information confidential, which precautions shall be no less stringent than those that the Collateral Agent and the Trustee, as applicable, employs to protect its own confidential information. Each of the Collateral Agent and the Trustee shall not disclose to any third party other than as set forth herein, and shall not use for any purpose other than the exercise of the Collateral Agent’s and the Trustee’s rights and the performance of its respective obligations under this Agreement, any such information without the prior written consent of such Grantor, as applicable. Each of the Collateral Agent and the Trustee shall limit access to such information received hereunder to (a) its directors, officers, managers and employees and (b) its legal advisors, to each of whom disclosure of such information is necessary for the purposes described above; provided, however, that in each case such party has expressly agreed to maintain such information in confidence under terms and conditions substantially identical to the terms of this Section 7.3(a).

(b) Each of the Collateral Agent and the Trustee agree that each Grantor does not have any responsibility whatsoever for any reliance on Confidential Information by the Collateral Agent or the Trustee or by any Person to whom such information is disclosed in connection with this Agreement, whether related to the purposes described above or otherwise. Without limiting the generality of the foregoing, each of the Collateral Agent and the Trustee agrees that the Grantor makes no representation or warranty whatsoever to it with respect to Confidential Information or its suitability for such purposes. Each of the Collateral Agent and the Trustee further agrees that it shall not acquire any rights against the Grantor or any employee, officer, director, manager, representative or agent of the Grantor (together with the Issuer, “Confidential Parties”) as a result of the disclosure of Confidential Information to the Trustee and that no Confidential Party has any duty, responsibility, liability or obligation to any Person as a result of any such disclosure.

(c) In the event the Collateral Agent or the Trustee is required to disclose any Confidential Information received hereunder in order to comply with any laws, regulations or court orders, it may disclose Confidential Information only to the extent necessary for such compliance; provided, however, that it shall give the Grantor, reasonable advance written notice of any such court proceeding in which such disclosure may be required pursuant to a court order so as to afford the Grantor full and fair opportunity to oppose the issuance of such order and to appeal therefrom and shall cooperate reasonably with the Grantor, as applicable, in opposing such order and in securing confidential treatment of any Confidential Information to be disclosed and/or obtaining a protective order narrowing the scope of such disclosure.

Section 7.4 Power of Attorney. Each Grantor, as to itself, hereby appoints the Collateral Agent and the Collateral Agent’s designee as such Grantor’s attorney, with power upon the occurrence and during the continuance of an Event of Default: (a) to endorse such Grantor’s name on any checks, notes, acceptances, money orders, or other forms of payment or security that come into the Collateral Agent’s or any Secured Parties’ possession; (b) to sign such Grantor’s name on any invoice, ▇▇▇▇ of lading, warehouse receipt, or other document of title relating to any Collateral, on drafts against customers, on assignments of Accounts, on notices of assignment, financing statements, and other public records and to file any such financing statements by electronic means with or without a signature as authorized or required by applicable law or filing procedure; (c) to notify the post office authorities to change the address

for delivery of such Grantor’s mail to an address designated by the Collateral Agent and to receive, open, and dispose of all mail addressed to such Grantor; (d) to send requests for verification of Accounts to customers or Account Debtors (but if any such Accounts constitute ABL First Lien Collateral, only so long as no Senior Liens are outstanding on such Collateral); (e) to clear Inventory through customs in such Grantor’s name, the Collateral Agent’s name, or the name of the Collateral Agent’s designee, and to sign and deliver to customs officials powers of attorney in such Grantor’s name for such purpose; and (f) to do all things the Collateral Agent reasonably determines are necessary to carry out the security interest provisions of the Indenture and the provisions of this Agreement. Each Grantor ratifies and approves all acts of such attorney. Notwithstanding anything in this Agreement or any Indenture Document to the contrary, none of the Trustee, the Collateral Agent, nor their attorneys, employees or Affiliates will be liable for any acts or omissions or for any error of judgment or mistake of fact or law other than any such liability arising from any such Person’s gross negligence or willful misconduct, as finally determined by a court of competent jurisdiction. Notwithstanding the foregoing, any rights and remedies provided in this Section 7.4 shall be subject to each Intercreditor Agreement (if any).

Section 7.5 NATURE OF APPOINTMENT; LIMITATION OF DUTY. THE APPOINTMENT OF THE COLLATERAL AGENT AS ATTORNEY-IN-FACT IN THIS ARTICLE VII IS COUPLED WITH AN INTEREST AND SHALL BE IRREVOCABLE UNTIL THE DATE ON WHICH THIS AGREEMENT IS TERMINATED IN ACCORDANCE WITH SECTION 8.13. NOTWITHSTANDING ANYTHING CONTAINED IN THIS AGREEMENT OR IN ANY INDENTURE DOCUMENT, NEITHER THE COLLATERAL AGENT, NOR ANY SECURED PARTY, NOR ANY OF THEIR RESPECTIVE AFFILIATES, OFFICERS, DIRECTORS, EMPLOYEES, AGENTS OR REPRESENTATIVES SHALL HAVE ANY DUTY TO EXERCISE ANY RIGHT OR POWER GRANTED HEREUNDER OR OTHERWISE OR TO PRESERVE THE SAME AND SHALL NOT BE LIABLE FOR ANY FAILURE TO DO SO OR FOR ANY DELAY IN DOING SO, EXCEPT TO THE EXTENT SUCH DAMAGES ARE ATTRIBUTABLE TO THEIR OWN GROSS NEGLIGENCE OR WILLFUL MISCONDUCT AS FINALLY DETERMINED BY A COURT OF COMPETENT JURISDICTION; PROVIDED THAT, IN NO EVENT SHALL THEY BE LIABLE FOR ANY PUNITIVE, EXEMPLARY, INDIRECT OR CONSEQUENTIAL DAMAGES.

Section 7.6 Additional Matters Relating to the Collateral Agent.

(a) The Collateral Agent. U.S. Bank National Association shall initially act as Collateral Agent for the Secured Parties and shall be authorized to appoint co-collateral agents as necessary in its sole discretion. U.S. Bank National Association, as Collateral Agent, is authorized and directed to (i) enter into the Indenture Documents, (ii) enter into Intercreditor Agreements, (iii) bind the Secured Parties on the terms as set forth in the Indenture Documents and any Intercreditor Agreement and (iv) perform and observe its obligations under the Indenture Documents and each Intercreditor Agreement (if any).

(b) Role of the Collateral Agent. The rights, duties, liabilities and immunities of the Collateral Agent and its appointment, resignation and replacement hereunder and under the Indenture and the other Indenture Documents shall be governed by this Agreement, Article 11 of the Indenture and the relevant provisions contained in the other Indenture Documents.

Without limiting the foregoing, the rights, privileges, protections and benefits given to the Collateral Agent under the Indenture are extended to, and shall be enforceable by, the Collateral Agent in connection with the execution, delivery and administration of this Agreement and the other Indenture Documents and any action taken or omitted to be taken by the Collateral Agent in connection with its appointment and performance under this Agreement and the other Indenture Documents to which it is a party.

(c) Absence of Fiduciary Relation. The Collateral Agent undertakes to perform or to observe only such of its agreements and obligations as are specifically set forth in this Agreement, the Indenture and the other Indenture Documents, and no implied agreements, covenants or obligations with respect to any Grantor or any Affiliate of any Grantor, any Secured Party or any other party shall be read into this Agreement against the Collateral Agent. The Collateral Agent in its capacity as such is not a fiduciary of and shall not owe or be deemed to owe any fiduciary duty to any Grantor or any Related Person of any Grantor.

(d) Exculpatory Provisions.

(i) None of the Collateral Agent, the Trustee or any of their respective officers, directors, employees, agents, attorneys-in-fact or Related Persons shall be responsible or liable in any manner (A) to any Grantor or any of their respective Related Persons for any action taken or omitted to be taken by it under or in connection with this Agreement in compliance herewith, (B) to any Secured Party or any other Person for any recitals, statements, representations, warranties, covenants or agreements contained in this Agreement or in any Indenture Document or in any certificate, report, statement or other document referred to or provided for in, or received by the Collateral Agent under or in connection with, this Agreement or any Indenture Document, (C) to any Secured Party or any other Person for the validity, effectiveness, adequacy, genuineness or enforceability of this Agreement or any Indenture Document, or any Lien purported to be created hereunder or under any Indenture Document, (D) to any Secured Party or any other Person for the validity or sufficiency of the Collateral or the validity of the title of any Grantor to the Collateral, for insuring the Collateral or for the payment of taxes, charges, assessments or Liens upon the Collateral or otherwise as to the maintenance of the Collateral or (E) to any Secured Party or other Person for any failure of any Grantor to perform its obligations hereunder or of the Issuer to perform any of the Obligations.

(ii) Notwithstanding anything to the contrary contained in this Agreement, (A) in no event shall the Trustee or the Collateral Agent be responsible for or have any obligation, duty or liability with respect to the creation, perfection, priority, maintenance, protection or enforcement of any Lien on, security interest in, pledge or other encumbrance involving or relating to the Collateral or any other assets, properties or rights of the Grantors, provided, however that the Collateral Agent acknowledges that with respect to the enforcement of any Liens, its actions will be subject to each Intercreditor Agreement (if any), (B) none of the Trustee or the Collateral Agent shall be responsible for filing any financing or continuation statements or recording any documents or instruments in any public office at any time or times or otherwise perfecting or maintaining the perfection of any Liens in the Collateral and (C) none of the Trustee or the Collateral Agent shall be under any obligation to any Person to ascertain or

to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement or to inspect the properties or records of any Grantor. The permissive rights of the Collateral Agent to do things enumerated in this Agreement shall not be construed as a duty or obligation. The Collateral Agent may rely conclusively on any Opinions of Counsel rendered to the Collateral Agent under Section 11.02 of the Indenture and otherwise under the Indenture in determining any necessary or desirable actions under this Agreement. Notwithstanding anything to the contrary herein, the Collateral Agent’s sole duty with respect to the custody, safekeeping and physical preservation of the Collateral in its possession, under the UCC or otherwise, shall be to deal with it in the same manner as the Collateral Agent deals with similar property for its own account and the Collateral Agent shall be deemed to have exercised reasonable care in the custody and preservation of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which comparable secured parties accord comparable collateral. None of the Collateral Agent or the Trustee shall be liable for failure to demand, collect or realize upon any of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of any Grantor or any other Person or to take any other action whatsoever with regard to the Collateral or any part thereof.

(iii) Notwithstanding anything to the contrary contained herein, none of the Collateral Agent, the Trustee or any of their respective officers, directors, employees, agents, attorneys-in-fact, or Related Persons shall be exonerated from any liability arising from its or their own gross negligence or willful misconduct, as finally determined by a court of competent jurisdiction.

(e) Fees and Expenses. The Grantors agree that they shall, jointly and severally, upon demand pay to the Collateral Agent and any Secured Party the amount of any and all reasonable out-of-pocket fees, costs and expenses (including the reasonable fees and expenses of their respective counsel, any special consultants reasonably engaged (and, unless an Event of Default exists, engaged only with the consent of the Issuer), and any local counsel who might reasonably be retained by the Collateral Agent or any Secured Party, as the case may be, in connection with the transactions contemplated hereby) that the Collateral Agent or any Secured Party, as the case may be, may incur in connection with (i) any Event of Default, including the sale, lease, license or other disposition of, collection from, or other realization upon, any of the Collateral pursuant to the exercise or enforcement of any of their respective rights hereunder, (ii) the exercise of their respective rights under this Agreement or under any Indenture Document, including the custody, preservation, use or operation of, or the sale of, any of the Collateral (iii) performance by the Collateral Agent of any obligations of any Grantor that any Grantor has failed or refused to perform with respect to the Collateral, (iv) bankruptcy, insolvency, receivership, foreclosure, winding up or liquidation proceedings and defending or asserting rights and claims of the Collateral Agent in respect thereof, by litigation or otherwise, including expenses of insurance, or (v) the execution and delivery and administration of this Agreement, each Intercreditor Agreement and the other Indenture Documents and, any agreement supplemental hereto or thereto, and any instruments of amendment, waiver, further assurance, release or termination, including with respect to the termination and/or release of any or all of the Liens in the Collateral provided for in this Agreement and the other Security Documents. Any amounts payable by any Grantor pursuant to this Section 7.6 shall be payable on demand.

(h) No Responsibility for Investments. In no event shall the Collateral Agent or any Secured Party be liable or responsible for any funds or investments of funds held by any Grantor or any Affiliates thereof.

Section 7.7 Appointment of Co-Collateral Agent. In the event that the Collateral Agent appoints a Co-Collateral Agent, or Co-Collateral Agents, in accordance with the provisions of Section 7.6(a) of this Agreement, such Co-Collateral Agent(s) shall enter into a Co-Collateral Agent Appointment Agreement in a form satisfactory to the Collateral Agent and such Co-Collateral Agent, and upon acceptance of the appointment, such Co-Collateral Agent shall be entitled to all of the rights, privileges, limitations on liability and immunities afforded to and subject to all the duties of the Collateral Agent hereunder, and shall be deemed to be a party to this Agreement for all purposes provided in this Section 7.7, in each case, subject to the specific rights and duties vested in the Co-Collateral Agent pursuant to the Co-Collateral Agent Appointment Agreement and related Security Documents. It is accepted and acknowledged by the parties hereto that any Co-Collateral Agent appointed in accordance with Section 7.6(a) and this Section 7.7 shall be entitled to the payment of its fees and expenses as agreed to by the Issuer, and without limitation of any of the other provisions of this Agreement, shall be deemed to be an indemnified party under Section 8.17 of this Agreement with respect to any liability arising under this Agreement or the other Indenture Documents without need for further act by the Issuer or the Subsidiary Parties.

Any party hereto may change its address or facsimile number for notices and other communications hereunder by notice to the other parties hereto (and for this purpose a notice to the Issuer shall be deemed to be a notice to each Grantor). All notices and other communications given to any party hereto in accordance with the provisions of this Agreement shall be deemed to have been given on the date of receipt if delivered by hand or overnight courier service or sent by facsimile or on the date five (5) Business Days after dispatch by certified or registered mail if mailed, in each case delivered, sent or mailed (properly addressed) to such party as provided in this Section 8.1 or in accordance with the latest unrevoked direction from such party given in accordance with this Section 8.1. Notwithstanding the foregoing, notices to the Collateral Agent shall only be effective upon actual receipt.

Section 8.2 Waiver of Notices. Unless otherwise expressly provided herein, each Grantor hereby waives presentment, demand, protest or any notice (to the maximum extent permitted by applicable law) of any kind in connection with this Agreement or any Collateral.

Section 8.3 Limitation on Collateral Agent’s and Secured Party’s Duty with Respect to the Collateral. The Collateral Agent shall have no obligation to clean-up or otherwise prepare the Collateral for sale. The Collateral Agent and each Secured Party shall use reasonable care with respect to the Collateral in its possession or under its control. Neither the Collateral Agent nor any Secured Party shall have any other duty as to any Collateral in its possession or control or in the possession or control of any agent or nominee of the Collateral Agent or such Secured Party, or any income thereon (other than to account for proceeds therefrom) or as to the preservation of rights against prior parties or any other rights pertaining thereto. To the extent that applicable law imposes duties on the Collateral Agent to exercise remedies in a commercially reasonable manner, and to the extent permitted by applicable law, each Grantor acknowledges and agrees that it would be commercially reasonable for the Collateral Agent (i) to fail to incur expenses deemed significant by the Collateral Agent to prepare Collateral for disposition or otherwise to transform raw material or work in process into finished goods or other finished products for disposition, (ii) to fail to obtain third party consents for access to Collateral to be disposed of, or to obtain or, if not required by other law, to fail to obtain governmental or third party consents for the collection or disposition of Collateral to be collected or disposed of, (iii) to fail to exercise collection remedies against Account Debtors or other Persons obligated on Collateral or to remove Liens on or any adverse claims against Collateral, (iv) 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, (v) to advertise dispositions of Collateral through publications or media of general circulation, whether or not the Collateral is of a specialized nature, (vi) to contact other Persons, whether or not in the same business as the Grantor, for expressions of interest in acquiring all or any portion of such Collateral, (vii) to hire one or more professional auctioneers to assist in the disposition of Collateral, whether or not the Collateral is of a specialized nature, (viii) 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 capacity of doing so, or that match buyers and sellers of assets, (ix) to dispose of assets in wholesale rather than retail markets, (x) to disclaim disposition warranties, such as title, possession or quiet enjoyment, (xi) to purchase insurance or credit enhancements to insure the Collateral Agent against risks of loss, collection or disposition of Collateral or to provide to the Collateral Agent a guaranteed return from the collection or disposition of Collateral, or (xii) to the extent deemed appropriate by the Collateral Agent, to obtain the services of other brokers, investment bankers, consultants and other professionals to assist the Collateral Agent in the collection or disposition of any of the Collateral. Each Grantor acknowledges that the purpose of this Section 8.3 is to provide non-exhaustive indications of what actions or omissions by the Collateral Agent would be commercially reasonable in the Collateral Agent’s exercise of remedies against the Collateral and that other actions or omissions by the Collateral Agent shall not be deemed commercially unreasonable solely on account of not being indicated in this Section 8.3. Without limitation upon the foregoing, nothing contained in this Section 8.3 shall be construed to grant any rights to any Grantor or to impose any duties on the Collateral Agent that would not have been granted or imposed by this Agreement or by applicable law in the absence of this Section 8.3.

Section 8.4 Compromises and Collection of Collateral. Each Grantor and the Collateral Agent recognize that setoffs, counterclaims, defenses and other claims may be asserted by obligors with respect to certain of the Accounts, that certain of the Accounts may be or become uncollectible in whole or in part and that the expense and probability of success in

litigating a disputed Account may exceed the amount that reasonably may be expected to be recovered with respect to an Account. In view of the foregoing, each Grantor agrees that the Collateral Agent may at any time and from time to time if an Event of Default has occurred and is continuing, (provided that if such Account constitutes ABL First Lien Collateral only so long as no Senior Liens are outstanding in on such Collateral), compromise with the obligor on any Account, accept in full payment of any Account such amount as the Collateral Agent in its sole discretion shall determine or abandon any Account, and any such action by the Collateral Agent shall be commercially reasonable so long as the Collateral Agent acts in good faith based on information known to it at the time it takes any such action.

Section 8.5 Specific Performance of Certain Covenants. Each Grantor acknowledges and agrees that a breach of any of the covenants contained in Sections 4.2(a), 4.5, 4.6, 4.7, 4.8, 4.10, 4.12, 5.1(j), 7.6, 8.11, 8.17 and 8.18, will cause irreparable injury to the Collateral Agent and the other Secured Parties, that the Collateral Agent and the other Secured Parties have no adequate remedy at law in respect of such breaches and therefore agrees, without limiting the right of the Collateral Agent or the other Secured Parties to seek and obtain specific performance of other obligations of any Grantor contained in this Agreement, that the covenants of such Grantor contained in the Sections referred to in this Section 8.5 shall be specifically enforceable against such Grantor.

Section 8.6 Cumulative Remedies; No Prior Recourse to Collateral. The enumeration herein of the Collateral Agent’s and the Trustee’s rights and remedies is not intended to be exclusive, and such rights and remedies are in addition to and not by way of limitation of any other rights or remedies that the Collateral Agent and the Trustee may have under the UCC, other applicable law or the Indenture Documents. The Collateral Agent and the Trustee shall have the right, in their sole discretion, to determine which rights and remedies are to be exercised and in which order. The exercise of one right or remedy shall not preclude the exercise of any others, all of which shall be cumulative. The Collateral Agent and the Trustee may, without limitation, proceed directly against any Person liable therefor to collect the Obligations without any prior recourse to the Collateral. No failure to exercise and no delay in exercising, on the part of the Collateral Agent or the Trustee, any right, remedy, power, or privilege hereunder, shall operate as a waiver thereof, nor shall any single or partial exercise of any right, remedy, power, or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power, or privilege.

Section 8.7 Limitation by Law; Severability of Provisions. All rights, remedies and powers provided in this Agreement may be exercised only to the extent that the exercise thereof does not violate any applicable provision of law, and all the provisions of this Agreement are intended to be subject to all applicable mandatory provisions of law that may be controlling and to be limited to the extent necessary so that they shall not render this Agreement invalid, unenforceable or not entitled to be recorded or registered, in whole or in part. The illegality or unenforceability of any provision of this Agreement or any instrument or agreement required hereunder shall not in any way affect or impair the legality or enforceability of the remaining provisions of this Agreement or any instrument or agreement required hereunder.

Section 8.8 Reinstatement. This Agreement shall remain in full force and effect and continue to be effective should any petition be filed by or against any Grantor for liquidation or reorganization, should any Grantor become insolvent or make an assignment for the benefit of any creditor or creditors or should a receiver or trustee be appointed for all or any significant part of such Grantor’s assets. This Agreement shall continue to be effective or be reinstated, as the case may be, if at any time when there is or has been more than one Grantor payment and performance of the Obligations, or any part thereof, is, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by any obligee of the Obligations, whether as a “voidable preference,” “fraudulent conveyance,” or otherwise, all as though such payment or performance had not been made. In the event that any such payment, or any part thereof, is rescinded, reduced, restored or returned, the Obligations shall be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned.
