Each Pledgor represents and warrants that the Collateral Agent has a perfected first priority security interest in all uncertificated Pledged Securities pledged by it hereunder that are in existence on the date hereof. Each Pledgor hereby agrees that if any of the Pledged Securities of a Wholly Owned Subsidiary that constitute “Securities” as defined in Section 8-102(a)(15) of the UCC are at any time not evidenced by certificates of ownership, then each applicable Pledgor shall, to the extent permitted by applicable law, cause the issuer to execute and deliver to the Collateral Agent an acknowledgment of the pledge of such Pledged Securities substantially in the form of Exhibit 1 hereto or such other form that is reasonably satisfactory to the Collateral Agent.

SECTION 3.3. Financing Statements and Other Filings; Maintenance of Perfected Security Interest. Each Pledgor represents and warrants that all financing statements, agreements, instruments and other documents necessary to perfect the security interest granted by it to the Collateral Agent on the date hereof in respect of the Pledged Collateral have been delivered, subject to the second paragraph of Section 11.2, to the Collateral Agent in completed and duly executed form for filing in each governmental, municipal or other office specified in Schedule 4 to the Perfection Certificate. Each Pledgor agrees that at the sole cost and expense of the Pledgors, such Pledgor will maintain the security interest created by this Agreement in the Pledged Collateral as a perfected first priority security interest subject only to Liens permitted under the definition of Permitted Liens.

SECTION 3.4. Other Actions. In order to further ensure the attachment, perfection and priority of, and the ability of the Collateral Agent to enforce, the Collateral Agent’s security interest in the Pledged Collateral, each Pledgor represents and warrants (as to itself) as follows and agrees, in each case at such Pledgor’s own expense, to take the following actions with respect to the following Pledged Collateral:

(a) Instruments and Tangible Chattel Paper. As of the date hereof, no amounts payable in excess of $500,000 (or solely with respect to intercompany Indebtedness of the Pledgors, no amounts payable) under or in connection with any of the Pledged Collateral are evidenced by any Instrument or Tangible Chattel Paper, other than such Instruments and Tangible Chattel Paper listed in Schedule 8 to the Perfection Certificate. Each Instrument and each item of Tangible Chattel Paper listed in Schedule 8 to the Perfection Certificate has been properly endorsed, assigned and delivered to the Collateral Agent, accompanied by instruments of transfer or assignment duly executed in blank. If any amount then payable under or in connection with any of the Pledged Collateral shall be evidenced by any Instrument or Tangible Chattel Paper, and such amount, together with all amounts payable evidenced by any Instrument or Tangible Chattel Paper not previously delivered to the Collateral Agent, exceeds $500,000 in the aggregate for all Pledgors (provided that solely with respect to intercompany Indebtedness of the Pledgors, such minimum threshold shall not apply), the Pledgor acquiring such Instrument or Tangible Chattel Paper shall promptly (but in any event within 15 days after receipt thereof or such longer period as the Collateral Agent may agree to in its sole discretion) endorse, assign and deliver the same to the Collateral Agent, accompanied by such instruments of transfer or assignment duly executed in blank as the Collateral Agent may from time to time reasonably request.

-12-

(b) Deposit Accounts. As of the date hereof, no Pledgor has any Deposit Accounts other than Excluded Deposit Accounts and those accounts listed in Schedule 11 to the Perfection Certificate. The Collateral Agent has a security interest in each such Deposit Account (other than Excluded Deposit Accounts), which security interest, when required by Section 6.17 of the Credit Agreement, will be perfected by Control. No Pledgor shall hereafter establish and maintain any Deposit Account unless (1) it shall have given the Collateral Agent 10 days’ prior written notice of its intention to establish such new Deposit Account with a Bank and (2) such Bank and such Pledgor shall have duly executed and delivered to the Collateral Agent a Deposit Account Control Agreement with respect to such Deposit Account. The Collateral Agent agrees with each Pledgor that the Collateral Agent shall not give any instructions directing the disposition of funds from time to time credited to any Deposit Account or withhold any withdrawal rights from such Pledgor with respect to funds from time to time credited to any Deposit Account unless an Event of Default has occurred and is continuing, and notice shall have been given by the Collateral Agent to the Issuer of its intent to exercise such rights. Each Pledgor agrees that once the Collateral Agent sends an instruction or notice to a Bank exercising its Control over any Deposit Account (other than Excluded Deposit Accounts) (with a copy of such instruction or notice to the Issuer) such Pledgor shall not give any instructions or orders with respect to such Deposit Account including, without limitation, instructions for distribution or transfer of any funds in such Deposit Account. No Pledgor shall grant Control of any Deposit Account to any person other than the Collateral Agent and the Administrative Agent.

(c) Securities Accounts and Commodity Accounts. (i) As of the date hereof, no Pledgor has any Securities Accounts or Commodity Accounts other than those listed in Schedule 11 to the Perfection Certificate. The Collateral Agent has a security interest in each such Securities Account and Commodity Account, which security interest, when required by Section 6.17 of the Credit Agreement, is perfected by Control. No Pledgor shall hereafter establish and maintain any Securities Account or Commodity Account with any Securities Intermediary or Commodity Intermediary unless (1) it shall have given the Collateral Agent 10 days’ prior written notice of its intention to establish such new Securities Account or Commodity Account with such Securities Intermediary or Commodity Intermediary and (2) such Securities Intermediary or Commodity Intermediary, as the case may be, and such Pledgor shall have duly executed and delivered a Control Agreement with respect to such Securities Account or Commodity Account, as the case may be. Each Pledgor shall accept any cash and Investment Property in trust for the benefit of the Collateral Agent and within one (1) Business Day of actual receipt thereof, deposit any and all cash and Investment Property received by it into a Deposit Account or Securities Account subject to Collateral Agent’s Control. The Collateral Agent agrees with each Pledgor that the Collateral Agent shall not give any Entitlement Orders or instructions or directions to any issuer of uncertificated securities, Securities Intermediary or Commodity Intermediary, and shall not withhold its consent to the exercise of any withdrawal or dealing rights by such Pledgor, unless an Event of Default has occurred and is continuing or, after giving effect to any such investment and withdrawal rights, would occur, and notice shall have been given by the Collateral Agent to the Issuer of its intent to exercise such rights. Each Pledgor agrees that once the

-13-

Collateral Agent sends an instruction or notice to a Securities Intermediary or Commodity Intermediary exercising its Control over any Securities Account and Commodity Account (with a copy of such instruction or notice to the Issuer) such Pledgor shall not give any instructions or orders with respect to such Securities Account and Commodity Account including, without limitation, instructions for investment, distribution or transfer of any Investment Property or Financial Asset maintained in such Securities Account or Commodity Account. No Pledgor shall grant Control over any Investment Property to any person other than the Collateral Agent and the Administrative Agent.

(ii) As between the Collateral Agent and the Pledgors, the Pledgors shall bear the investment risk with respect to the Investment Property and Pledged Securities, and the risk of loss of, damage to, or the destruction of the Investment Property and Pledged Securities, whether in the possession of, or maintained as a Security Entitlement or deposit by, or subject to the Control of, the Collateral Agent, a Securities Intermediary, a Commodity Intermediary, any Pledgor or any other person.

(d) Electronic Chattel Paper and Transferable Records. As of the date hereof, no amount under or in connection with any of the Pledged Collateral is evidenced by 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) other than such Electronic Chattel Paper and transferable records (i) listed in Schedule 8 to the Perfection Certificate or (ii) whose value does not exceed $500,000 in the aggregate for all Pledgors. If any amount payable under or in connection with any of the Pledged Collateral shall be evidenced by any Electronic Chattel Paper or any transferable record, the Pledgor acquiring such Electronic Chattel Paper or transferable record shall promptly notify the Collateral Agent thereof and shall take such action to vest in the Collateral Agent control of such Electronic Chattel Paper under Section 9-105 of the UCC or control 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, or such transferable record. The requirement in the preceding sentence shall not apply to the extent that such amount, together with all amounts payable evidenced by Electronic Chattel Paper or any transferable record in which the Collateral Agent has not been vested control within the meaning of the statutes described in the immediately preceding sentence, does not exceed $500,000 in the aggregate for all Pledgors. The Collateral Agent agrees with such Pledgor 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, for the Pledgor to make alterations to the Electronic Chattel Paper or transferable record permitted under Section 9-105 of the UCC 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, unless an Event of Default has occurred and is continuing or would occur after taking into account any action by such Pledgor with respect to such Electronic Chattel Paper or transferable record.

-14-

(e) Letter-of-Credit Rights. If any Pledgor is at any time a beneficiary under a Letter of Credit now or hereafter issued in favor of such Pledgor that is not a Supporting Obligation, such Pledgor shall promptly notify the Collateral Agent thereof and such Pledgor shall, pursuant to an agreement (which shall be, prior to the Discharge of the Credit Agreement Obligations, substantially identical to the form delivered under the Credit Agreement Documents), either (i) use commercially reasonable efforts to arrange for the issuer and any confirmer of such Letter of Credit to consent to an assignment to the Collateral Agent of the proceeds of any drawing under the Letter of Credit or (ii) use commercially reasonable efforts to arrange for the Collateral Agent to become the transferee beneficiary of such Letter of Credit, with the Collateral Agent agreeing, in each case, that the proceeds of any drawing under the Letter of Credit are to be paid to the applicable Pledgor unless an Event of Default has occurred and is continuing. The actions in the preceding sentence shall not be required to the extent that the amount of any such Letter of Credit, together with the aggregate amount of all other Letters of Credit for which the actions described above in clauses (i) and (ii) have not been taken, does not exceed $500,000 in the aggregate for all Pledgors.

(f) Commercial Tort Claims. As of the date hereof, each Pledgor hereby represents and warrants that it holds no Commercial Tort Claims other than those listed in Schedule 10 to the Perfection Certificate. If any Pledgor shall at any time hold or acquire a Commercial Tort Claim, such Pledgor shall promptly (but in any event within 15 days or such longer period as the Collateral Agent may agree, in its sole discretion) notify the Collateral Agent in writing signed by such Pledgor of the brief details thereof and grant to the Collateral Agent in such writing a security interest therein and in the Proceeds thereof, all upon the terms of this Agreement (with such writing to be, prior to the Discharge of the Credit Agreement Obligations, in a form substantially identical to the form delivered under the Credit Agreement Documents). The requirement in the preceding sentence shall not apply to the extent that the amount of such Commercial Tort Claim, together with the amount of all other Commercial Tort Claims held by any Pledgor in which the Collateral Agent does not have a security interest, does not exceed $500,000 in the aggregate for all Pledgors.

SECTION 3.5. Joinder of Additional Guarantors. The Pledgors shall cause each Subsidiary of the Issuer which, from time to time, after the date hereof shall be required to pledge any assets to the Collateral Agent for the benefit of the Secured Parties pursuant to the provisions of the Indenture, to execute and deliver to the Collateral Agent a Joinder Agreement substantially in the form of Exhibit 3 hereto, within thirty (30) days of the date on which it was acquired or created and, upon such execution and delivery, such Subsidiary shall constitute a “Guarantor” and a “Pledgor” for all purposes hereunder with the same force and effect as if originally named as a Guarantor and Pledgor herein. The execution and delivery of such Joinder Agreement shall not require the consent of any Pledgor hereunder. The rights and obligations of each Pledgor hereunder shall remain in full force and effect notwithstanding the addition of any new Guarantor and Pledgor as a party to this Agreement.

SECTION 3.6. Supplements; Further Assurances. Each Pledgor shall take such further actions, and execute and/or deliver to the Collateral Agent such additional financing

-15-

statements, amendments, assignments, agreements, supplements, powers and instruments, as may be necessary or as the Collateral Agent may reasonably request in order to create, perfect, preserve and protect the security interest in the Pledged Collateral as provided herein and the rights and interests granted to the Collateral Agent hereunder, to carry into effect the purposes hereof or better to assure and confirm the validity, enforceability and priority of the Collateral Agent’s security interest in the Pledged Collateral or permit the Collateral Agent to exercise and enforce its rights, powers and remedies hereunder with respect to any Pledged Collateral, including the filing of financing statements, continuation statements and other documents (including this Agreement) under the Uniform Commercial Code (or other similar laws) in effect in any jurisdiction with respect to the security interest created hereby and the execution and delivery of Control Agreements, in such offices (including the United States Patent and Trademark Office and the United States Copyright Office) wherever required by law to perfect, continue and maintain the validity, enforceability and priority of the security interest in the Pledged Collateral as provided herein and to preserve the other rights and interests granted to the Collateral Agent hereunder, as against third parties, with respect to the Pledged Collateral (each of which shall be, prior to the Discharge of the Credit Agreement Obligations, in a form substantially identical to the form delivered or performed under the Credit Agreement Documents). If an Event of Default has occurred and is continuing, the Collateral Agent may institute and maintain, in its own name or in the name of any Pledgor, such suits and proceedings as the Collateral Agent may be advised by counsel shall be necessary or expedient to prevent any impairment of the security interest in or the perfection thereof in the Pledged Collateral. All of the foregoing shall be at the sole cost and expense of the Pledgors.

SECTION 3.7. Information Regarding Collateral. Each Pledgor shall provide to the Collateral Agent not less than 30 days’ prior written notice (in the form of a certificate of a Responsible Officer), or such lesser notice period agreed to by the Collateral Agent, of its intention so to do, describing such change and providing such other information in connection therewith as the Collateral Agent may reasonably request, before effecting any change (i) in any Pledgor’s legal name, (ii) in the location of any Pledgor’s chief executive office, (iii) in any Pledgor’s identity or organizational structure, (iv) in any Pledgor’s Federal Taxpayer Identification Number or organizational identification number, if any, or (v) in any Pledgor’s jurisdiction of organization (in each case, including by merging with or into any other entity, reorganizing, dissolving, liquidating, reorganizing or organizing in any other jurisdiction), it being understood that the Issuer shall take, and the Issuer shall cause each applicable Pledgor to take, all action necessary or reasonably requested by the Collateral Agent to maintain the perfection and priority of the security interest of the Collateral Agent for the benefit of the Secured Parties in the Pledged Collateral, if applicable. The Issuer agrees to promptly provide the Collateral Agent with certified Organizational Documents reflecting any of the changes described in the preceding sentence.

PROPERTY COLLATERAL

SECTION 6.1. Grant of Intellectual Property License. For the purpose of enabling the Collateral Agent, during the continuance of an Event of Default, to exercise rights and remedies under Article IX hereof at such time as the Collateral Agent shall be lawfully entitled to exercise such rights and remedies, and for no other purpose, each Pledgor hereby grants to the Collateral Agent, to the extent assignable, an irrevocable, non-exclusive license to use, assign, license or sublicense any of the Intellectual Property Collateral now owned or hereafter acquired by such Pledgor, wherever the same may be located. Such license shall include access to all media in which any of the licensed items may be recorded or stored and to all computer programs used for the compilation or printout hereof. Nothing in this Section 6.1 shall require Pledgors to grant any license that is prohibited by any requirement of law, or is prohibited by, or constitutes a breach or default under or results in the termination of or gives rise to any right of acceleration, modification or cancellation under any Contract (for as long as, such prohibition is not terminated or rendered unenforceable or otherwise deemed ineffective by the Uniform Commercial Code, any other requirement of law or principles of equity); provided, further, that such licenses to be granted hereunder with respect to Trademarks shall be subject to the maintenance of quality standards with respect to the goods and services on which such Trademarks are used sufficient to preserve the validity of such Trademarks.

SECTION 6.2. Protection of Collateral Agent’s Security. Except where the failure to do so could not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect, on a continuing basis, each Pledgor shall, at its sole cost and expense, (i) promptly following its becoming aware thereof, notify the Collateral Agent of any adverse determination in any proceeding in any federal, state or local court or administrative body or in the United States Patent and Trademark Office or the United States Copyright Office regarding any Material Intellectual Property Collateral, such Pledgor’s right to register such Material Intellectual Property Collateral or its right to keep and maintain such registration in full force and effect, (ii) maintain all Material Intellectual Property Collateral as presently used and operated, (iii) not permit to lapse or become abandoned any Material Intellectual Property Collateral, and not settle or compromise any pending or future litigation or administrative proceeding with respect to any such Material Intellectual Property Collateral, in either case except as shall be consistent with commercially reasonable business judgment, (iv) following such Pledgor obtaining knowledge thereof, promptly notify the Collateral Agent in writing of any event which may be reasonably expected to materially and adversely affect the value or utility of any Material Intellectual Property Collateral or the rights and remedies of the Collateral Agent in relation thereto including a levy or threat of levy or any legal process against any Material Intellectual Property Collateral, (v) not license any Intellectual Property Collateral other than licenses entered into by such Pledgor in, or incidental to, the ordinary course of business, or amend or permit the amendment of any of the licenses in a manner that materially and adversely affects the right to receive payments thereunder, or in any manner that would materially impair the value of any Intellectual Property Collateral or the Lien on and security interest in the Intellectual Property Collateral created therein hereby, without the consent of the Collateral Agent,

-21-

(vi) diligently keep adequate records respecting all Intellectual Property Collateral and (vii) furnish to the Collateral Agent from time to time upon the Collateral Agent’s reasonable request therefor, reasonably detailed statements and amended schedules further identifying and describing the United States federal registered and applied for Intellectual Property Collateral and such other materials evidencing or reports pertaining to any Intellectual Property Collateral.

SECTION 6.3. After-Acquired Property. If any Pledgor shall at any time after the date hereof (i) obtain any rights to any additional Intellectual Property Collateral or (ii) become entitled to the benefit of any additional Intellectual Property Collateral or any renewal or extension thereof, including any reissue, division, continuation, or continuation-in-part of any Intellectual Property Collateral, or any improvement on any Intellectual Property Collateral, or if any intent-to use trademark application is no longer subject to clause (vi) of the definition of “Excluded Property,” the provisions hereof shall automatically apply thereto and any such item enumerated in the preceding clause (i) or (ii) shall automatically constitute Intellectual Property Collateral as if such would have constituted Intellectual Property Collateral at the time of execution hereof and be subject to the Lien and security interest created by this Agreement without further action by any party. Each Pledgor shall promptly provide to the Collateral Agent written notice of any of the foregoing and confirm the attachment of the Lien and security interest created by this Agreement to any rights described in clauses (i) and (ii) above by execution of an instrument and the filing of any instruments or statements as shall be reasonably necessary to create, preserve, protect or perfect the Collateral Agent’s security interest in such Intellectual Property Collateral (each of which shall be, prior to the Discharge of the Credit Agreement Obligations, in a form substantially identical to the form delivered under the Credit Agreement Documents). Further, the Collateral Agent is hereby irrevocably authorized by each Pledgor (but shall not be obligated) to modify this Agreement by amending Schedules 9(a) and 9(b) to the Perfection Certificate to include any Intellectual Property Collateral that is registered, or whose registration has been applied for, with the United States Patent and Trademark Office or United States Copyright Office (or any successor office) of such Pledgor acquired or arising after the date hereof.

SECTION 6.4. Litigation. Except where the failure to do so could not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect, each Pledgor agrees to take all commercially reasonable actions necessary, whether by suit, proceeding or other action, to prevent the infringement, counterfeiting, unfair competition, dilution, diminution in value of or other damage to any of the Material Intellectual Property Collateral owned by such Pledgor.

SECTION 6.5. Permitted Disposal of Intellectual Property Collateral. Nothing in this Agreement prevents any Pledgor from disposing of, discontinuing the use or maintenance of, failing to pursue or otherwise allowing to lapse, terminate or put into the public domain any of its Intellectual Property Collateral to the extent permitted by the Indenture if such Pledgor determines in its reasonable business judgment that such action is desirable in the conduct of its business.

Each Pledgor shall, at such Pledgor’s sole cost and expense, upon the Collateral Agent’s demand made at any time after the occurrence and during the continuance of any Event of Default, deliver all tangible evidence of Receivables, including all documents evidencing Receivables and any books and records relating thereto to the Collateral Agent or to its representatives (copies of which evidence and books and records may be retained by such Pledgor). Upon the occurrence and during the continuance of any Event of Default, the Collateral Agent may transfer a full and complete copy of any Pledgor’s books, records, credit information, reports, memoranda and all other writings relating to the Receivables to and for the use by any person that has acquired or is contemplating acquisition of an interest in the Receivables or the Collateral Agent’s security interest therein without the consent of any Pledgor.

SECTION 7.2. Legend. After the occurrence and during the continuance of an Event of Default and after notice thereof is given to the Pledgors by the Administrative Agent or by the Collateral Agent (which shall be given at the request of the Holders in accordance with the Indenture), each Pledgor shall legend the Receivables and the other books, records and documents of such Pledgor evidencing or pertaining to the Receivables with an appropriate reference to the fact that the Receivables have been assigned to the Collateral Agent for the benefit of the Secured Parties and that the Collateral Agent has a security interest therein.

TRANSFERS

ARTICLE IX

REMEDIES

SECTION 9.1. Remedies. Upon the occurrence and during the continuance of any Event of Default, the Collateral Agent may from time to time exercise in respect of the Pledged Collateral, in addition to the other rights and remedies provided for herein or otherwise available to it, the following remedies:

(i) Personally, or by agents or attorneys, immediately take possession of the Pledged Collateral or any part thereof, from any Pledgor or any other person who then

-23-

has possession of any part thereof with or without notice or process of law, and for that purpose may enter upon any Pledgor’s premises where any of the Pledged Collateral is located, remove such Pledged Collateral, remain present at such premises to receive copies of all communications and remittances relating to the Pledged Collateral and use in connection with such removal and possession any and all services, supplies, aids and other facilities of any Pledgor;

(ii) Demand, ▇▇▇ for, collect or receive any money or property at any time payable or receivable in respect of the Pledged Collateral including instructing the obligor or obligors on any agreement, instrument or other obligation constituting part of the Pledged Collateral to make any payment required by the terms of such agreement, instrument or other obligation directly to the Collateral Agent, and in connection with any of the foregoing, compromise, settle, extend the time for payment and make other modifications with respect thereto; provided, however, that in the event that any such payments are made directly to any Pledgor, prior to receipt by any such obligor of such instruction, such Pledgor shall segregate all amounts received pursuant thereto in trust for the benefit of the Collateral Agent and shall promptly (but in no event later than one (1) Business Day after receipt thereof) pay such amounts to the Collateral Agent;

(iii) Sell, assign, grant a license to use or otherwise liquidate, or direct any Pledgor to sell, assign, grant a license to use or otherwise liquidate, any and all investments made in whole or in part with the Pledged Collateral or any part thereof, and take possession of the proceeds of any such sale, assignment, license or liquidation;

(iv) Take possession of the Pledged Collateral or any part thereof, by directing any Pledgor in writing to deliver the same to the Collateral Agent at any place or places so designated by the Collateral Agent, in which event such Pledgor shall at its own expense: (A) forthwith cause the same to be moved to the place or places designated by the Collateral Agent and therewith delivered to the Collateral Agent, (B) store and keep any Pledged Collateral so delivered to the Collateral Agent at such place or places pending further action by the Collateral Agent and (C) while the Pledged Collateral shall be so stored and kept, provide such security and maintenance services as shall be necessary to protect the same and to preserve and maintain them in good condition. Each Pledgor’s obligation to deliver the Pledged Collateral as contemplated in this Section 9.1(iv) is of the essence hereof. Upon application to a court of equity having jurisdiction, the Collateral Agent shall be entitled to a decree requiring specific performance by any Pledgor of such obligation;

(v) Withdraw all moneys, instruments, securities and other property in any bank, financial securities, deposit or other account of any Pledgor constituting Pledged Collateral for application to the Obligations as provided in Article X hereof;

(vi) Retain and apply the Distributions to the Obligations as provided in Article X hereof;

-24-

(vii) Exercise any and all rights as beneficial and legal owner of the Pledged Collateral, including perfecting assignment of and exercising any and all voting, consensual and other rights and powers with respect to any Pledged Collateral; and

(viii) Exercise all the rights and remedies of a secured party on default under the UCC, and the Collateral Agent may also, without notice except as specified in Section 9.2 hereof, sell, assign or grant a license to use the Pledged Collateral or any part thereof in one or more parcels at public or private sale, at any exchange, broker’s board or at any of the Collateral Agent’s offices or elsewhere, for cash, on credit or for future delivery, and at such price or prices and upon such other terms as may be obtained by the Collateral Agent. The Collateral Agent or any other Secured Party or any of their respective Affiliates may be the purchaser, licensee, assignee or recipient of the Pledged Collateral or any part thereof at any such sale and shall be entitled, for the purpose of bidding and making settlement or payment of the purchase price for all or any portion of the Pledged Collateral sold, assigned or licensed at such sale, to use and apply any of the Obligations owed to such person as a credit on account of the purchase price of the Pledged Collateral or any part thereof payable by such person at such sale. Each purchaser, assignee, licensee or recipient at any such sale shall acquire the property sold, assigned or licensed absolutely free from any claim or right on the part of any Pledgor, and each Pledgor hereby waives, to the fullest extent permitted by law, all rights of redemption, stay and/or appraisal which it now has or may at any time in the future have under any rule of law or statute now existing or hereafter enacted. The Collateral Agent shall not be obligated to make any sale of the Pledged Collateral or any part thereof regardless of notice of sale having been given. The Collateral Agent may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned. Each Pledgor hereby waives, to the fullest extent permitted by law, any claims against the Collateral Agent arising by reason of the fact that the price at which the Pledged Collateral or any part thereof may have been sold, assigned or licensed at such a private sale was less than the price which might have been obtained at a public sale, even if the Collateral Agent accepts the first offer received and does not offer such Pledged Collateral to more than one offeree.

SECTION 9.2. Notice of Sale. Each Pledgor acknowledges and agrees that, to the extent notice of sale or other disposition of the Pledged Collateral or any part thereof shall be required by law, ten (10) days’ prior notice to such Pledgor of the time and place of any public sale or of the time after which any private sale or other intended disposition is to take place shall be commercially reasonable notification of such matters. No notification need be given to any Pledgor if it has signed, after the occurrence of an Event of Default, a statement renouncing or modifying any right to notification of sale or other intended disposition.

SECTION 9.3. Waiver of Notice and Claims. Each Pledgor hereby waives, to the fullest extent permitted by applicable law, notice or judicial hearing in connection with the Collateral Agent’s taking possession or the Collateral Agent’s disposition of the Pledged Collateral or any part thereof, including any and all prior notice and hearing for any prejudgment remedy or remedies and any such right which such Pledgor would otherwise have under law, and

-25-

each Pledgor hereby further waives, to the fullest extent permitted by applicable law: (i) all damages occasioned by such taking of possession, (ii) all other requirements as to the time, place and terms of sale or other requirements with respect to the enforcement of the Collateral Agent’s rights hereunder and (iii) all rights of redemption, appraisal, valuation, stay, extension or moratorium now or hereafter in force under any applicable law. The Collateral Agent shall not be liable for any incorrect or improper payment made pursuant to this Article IX in the absence of gross negligence or willful misconduct on the part of the Collateral Agent. Any sale of, or the grant of options to purchase, or any other realization upon, any Pledged Collateral shall operate to divest all right, title, interest, claim and demand, either at law or in equity, of the applicable Pledgor therein and thereto, and shall be a perpetual bar both at law and in equity against such Pledgor and against any and all persons claiming or attempting to claim the Pledged Collateral so sold, optioned or realized upon, or any part thereof, from, through or under such Pledgor.

SECTION 9.4. Certain Sales of Pledged Collateral.

(a) Each Pledgor recognizes that, by reason of certain prohibitions contained in law, rules, regulations or orders of any Governmental Authority, the Collateral Agent may be compelled, with respect to any sale of all or any part of the Pledged Collateral, to limit purchasers to those who meet the requirements of such Governmental Authority. Each Pledgor acknowledges that any such sales may be at prices and on terms less favorable to the Collateral Agent than those obtainable through a public sale without such restrictions, and, notwithstanding such circumstances, agrees that any such restricted sale shall be deemed to have been made in a commercially reasonable manner and that, except as may be required by applicable law, the Collateral Agent shall have no obligation to engage in public sales.

(b) Each Pledgor recognizes that, by reason of certain prohibitions contained in the Securities Act, and applicable state securities laws, the Collateral Agent may be compelled, with respect to any sale of all or any part of the Securities Collateral and Investment Property, to limit purchasers to persons who will agree, among other things, to acquire such Securities Collateral or Investment Property for their own account, for investment and not with a view to the distribution or resale thereof. Each Pledgor acknowledges that any such private sales may be at prices and on terms less favorable to the Collateral Agent than those obtainable through a public sale without such restrictions (including a public offering made pursuant to a registration statement under the Securities Act), and, notwithstanding such circumstances, agrees that any such private sale shall be deemed to have been made in a commercially reasonable manner and that the Collateral Agent shall have no obligation to engage in public sales and no obligation to delay the sale of any Securities Collateral or Investment Property for the period of time necessary to permit the issuer thereof to register it for a form of public sale requiring registration under the Securities Act or under applicable state securities laws, even if such issuer would agree to do so.

(c) Notwithstanding the foregoing, each Pledgor shall, upon the occurrence and during the continuance of any Event of Default, at the reasonable request of the Collateral Agent, for the benefit of the Collateral Agent, cause any registration, qualification under or compliance with any Federal or state securities law or laws to be effected with respect to all or any part of the Securities Collateral as soon as practicable and at the sole cost and expense of the

-26-

Pledgors. Each Pledgor will use its commercially reasonable efforts to cause such registration to be effected (and be kept effective) and will use its commercially reasonable efforts to cause such qualification and compliance to be effected (and be kept effective) as may be so requested and as would permit or facilitate the sale and distribution of such Securities Collateral including registration under the Securities Act (or any similar statute then in effect), qualifications under applicable blue sky or other state securities laws and compliance with all other requirements of any Governmental Authority. Each Pledgor shall use its commercially reasonable efforts to cause the Collateral Agent to be kept advised in writing as to the progress of each such registration, qualification or compliance and as to the completion thereof, shall furnish to the Collateral Agent such number of prospectuses, offering circulars or other documents incident thereto as the Collateral Agent from time to time may reasonably request (it being understood that the Collateral Agent shall have no obligation to make such request) and shall indemnify and shall cause the issuer of the Securities Collateral to indemnify the Collateral Agent and all others participating in the distribution of such Securities Collateral against all claims, losses, damages and liabilities caused by any untrue statement (or alleged untrue statement) of a material fact contained therein (or in any related registration statement, notification or the like) or by any omission (or alleged omission) to state therein (or in any related registration statement, notification or the like) a material fact required to be stated therein or necessary to make the statements therein not misleading.

(d) If the Collateral Agent determines to exercise its right to sell any or all of the Securities Collateral or Investment Property, upon written request, the applicable Pledgor shall from time to time furnish to the Collateral Agent all such information as the Collateral Agent may reasonably request in order to determine the number of securities included in the Securities Collateral or Investment Property which may be sold by the Collateral Agent as exempt transactions under the Securities Act and the rules of the Securities and Exchange Commission thereunder, as the same are from time to time in effect.

(e) Each Pledgor further agrees that a breach of any of the covenants contained in this Section 9.4 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 breach and, as a consequence, that each and every covenant contained in this Section 9.4 shall be specifically enforceable against such Pledgor, and such Pledgor hereby waives and agrees not to assert any defenses against an action for specific performance of such covenants except for a defense that no Event of Default has occurred and is continuing.

SECTION 9.5. No Waiver; Cumulative Remedies.

(a) No failure on the part of the Collateral Agent to exercise, no course of dealing with respect to, and no delay on the part of the Collateral Agent in exercising, any right, power or remedy hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any such right, power, privilege or remedy hereunder preclude any other or further exercise thereof or the exercise of any other right, power, privilege or remedy; nor shall the Collateral Agent be required to look first to, enforce or exhaust any other security, collateral or guaranties. All rights and remedies herein provided are cumulative and are not exclusive of any rights or remedies provided by law or otherwise available.

-27-

(b) In the event that the Collateral Agent shall have instituted any proceeding to enforce any right, power, privilege or remedy under this Agreement or any other Notes Document by foreclosure, sale, entry or otherwise, and such proceeding shall have been discontinued or abandoned for any reason or shall have been determined adversely to the Collateral Agent, then and in every such case, the Pledgors, the Collateral Agent and each other Secured Party shall be restored to their respective former positions and rights hereunder with respect to the Pledged Collateral, and all rights, remedies, privileges and powers of the Collateral Agent and the other Secured Parties shall continue as if no such proceeding had been instituted.

SECTION 9.6. Certain Additional Actions Regarding Intellectual Property. If any Event of Default shall have occurred and be continuing, upon the written demand of the Collateral Agent, each Pledgor shall execute and deliver to the Collateral Agent an assignment or assignments of the registered Patents, Trademarks and/or Copyrights and Goodwill and such other documents as are necessary to carry out the intent and purposes hereof. Within five (5) Business Days of written notice thereafter from the Collateral Agent, each Pledgor shall use commercially reasonable efforts to make available to the Collateral Agent, to the extent within such Pledgor’s power and authority, such personnel in such Pledgor’s employ on the date of the Event of Default as the Collateral Agent may reasonably request to permit such Pledgor to continue, directly or indirectly, to produce, advertise and sell the products and services sold by such Pledgor under the registered Patents, Trademarks and/or Copyrights, and each Pledgor shall use commercially reasonable efforts to make such persons available to perform their prior functions on the Collateral Agent’s behalf.

ARTICLE X

APPLICATION OF PROCEEDS

SECTION 10.1. Application of Proceeds. The proceeds received by the Collateral Agent in respect of any sale of, collection from or other realization upon all or any part of the Pledged Collateral pursuant to the exercise by the Collateral Agent of its remedies shall be applied, together with any other sums then held by the Collateral Agent pursuant to this Agreement, in accordance with the Intercreditor Agreement.

ARTICLE XI

MISCELLANEOUS

SECTION 11.1. Concerning Collateral Agent.

(a) The Collateral Agent has been appointed as Collateral Agent pursuant to the Indenture. The actions of the Collateral Agent hereunder are subject to the provisions of the Indenture. The Collateral Agent shall have the right hereunder to make demands, to give notices, to exercise or refrain from exercising any rights, and to take or refrain from taking action (including the release or substitution of the Pledged Collateral), in accordance with this Agreement and the Indenture. The Collateral Agent may employ agents and attorneys-in-fact in connection herewith and shall not be liable for any acts or omissions of any such agents or attorneys-in-fact selected by it in good faith. The Collateral Agent may resign and a successor

-28-

Collateral Agent may be appointed in the manner provided in the Indenture. Upon the acceptance of any appointment as the Collateral Agent by a successor Collateral Agent, that successor Collateral Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Collateral Agent under this Agreement, and the retiring Collateral Agent shall thereupon be discharged from its duties and obligations under this Agreement. After any retiring Collateral Agent’s resignation, the provisions hereof shall inure to its benefit as to any actions taken or omitted to be taken by it under this Agreement while it was the Collateral Agent.

(b) The Collateral Agent shall be deemed to have exercised reasonable care in the custody and preservation of the Pledged Collateral in its possession if such Pledged Collateral is accorded treatment substantially equivalent to that which the Collateral Agent generally accords property consisting of similar instruments or interests held for the benefit of third parties, it being understood that neither the Collateral Agent nor any of the Secured Parties shall have responsibility for (i) ascertaining or taking action with respect to calls, conversions, exchanges, maturities, tenders or other matters relating to any Securities Collateral, whether or not the Collateral Agent or any other Secured Party has or is deemed to have knowledge of such matters or (ii) taking any necessary steps to preserve rights against any person with respect to any Pledged Collateral.

(c) The Collateral Agent shall be entitled to rely upon any written notice, statement, certificate, order or other document or any telephone message believed by it to be genuine and correct and to have been signed, sent or made by the proper person, and, with respect to all matters pertaining to this Agreement and its duties hereunder, upon advice of counsel selected by it.

(d) If any item of Pledged Collateral also constitutes collateral granted to the Collateral Agent under any other deed of trust, mortgage, security agreement, pledge or instrument of any type, in the event of any conflict between the provisions hereof and the provisions of such other deed of trust, mortgage, security agreement, pledge or instrument of any type in respect of such collateral, the provisions hereof shall control.

(e) The Collateral Agent may rely on a certificate of the Issuer as to whether any or all UCC financing statements of the Pledgors need to be amended as a result of any of the changes (i) in any Obligor’s legal name, (ii) in the location of any Obligor’s chief executive office, (iii) in any Obligor’s identity or organizational structure, (iv) in any Obligor’s Federal Taxpayer Identification Number or organizational identification number, if any, or (v) in any Obligor’s jurisdiction of organization (in each case, including by merging with or into any other entity, reorganizing, dissolving, liquidating, reorganizing or organizing in any other jurisdiction). If any Pledgor fails to provide information to the Collateral Agent about such changes on a timely basis, the Collateral Agent shall not be liable or responsible to any party for any failure to maintain a perfected security interest in such Pledgor’s property constituting Pledged Collateral, for which the Collateral Agent needed to have information relating to such changes. The Collateral Agent shall have no duty to inquire about such changes if any Pledgor does not inform the Collateral Agent of such changes, the parties acknowledging and agreeing that it would not be feasible or practical for the Collateral Agent to search for information on such changes if such information is not provided by any Pledgor.

-29-

(f) Notwithstanding anything contained herein to the contrary, the Collateral Agent shall be entitled to the same rights, protections, immunities and indemnities as set forth in the Indenture as if the provisions setting forth those rights, protections, immunities and indemnities are fully set forth herein.

SECTION 11.2. Intercreditor Agreement. Notwithstanding anything herein to the contrary, the Liens and security interests granted to the Collateral Agent pursuant to this Agreement and the exercise of any right or remedy by the Collateral Agent hereunder are subject to the terms of the Intercreditor Agreement. In the event of any conflict between the terms of the Intercreditor Agreement and the terms of this Agreement, the terms of the Intercreditor Agreement shall govern and control. Notwithstanding anything herein to the contrary, prior to the Discharge of the Credit Agreement Obligations, all requirements of any Pledgor pursuant to this Agreement to endorse, assign, transfer or otherwise deliver any Pledged Collateral to the Collateral Agent shall be deemed satisfied by endorsement, assignment or delivery of such Pledged Collateral to the Administrative Agent pursuant to the Credit Agreement Documents. Any endorsement, assignment, transfer or delivery to or Control by the Administrative Agent shall be deemed an endorsement, assignment, transfer or delivery to or Control by the Collateral Agent for all purposes hereunder.

THIS SECURITY AGREEMENT IS SUBJECT TO THE PROVISIONS OF THE INTERCREDITOR AGREEMENT DATED AS OF MAY 7, 2010 (AS AMENDED, SUPPLEMENTED OR OTHERWISE MODIFIED FROM TIME TO TIME), AMONG C.P. ATLAS ACQUISITION CORP. (TO BE MERGED WITH AND INTO AMERICAN RENAL HOLDINGS INC.), THE GRANTORS PARTY THERETO, BANK OF AMERICA, N.A., AS CREDIT AGREEMENT ADMINISTRATIVE AGENT, WILMINGTON TRUST FSB, AS SENIOR SECURED NOTES COLLATERAL AGENT AND EACH ADDITIONAL NOTES COLLATERAL AGENT FROM TIME TO TIME PARTY THERETO.

SECTION 11.3. Collateral Agent May Perform; Collateral Agent Appointed Attorney-in-Fact. If any Pledgor shall fail to perform any covenants contained in this Agreement or if any representation or warranty on the part of any Pledgor contained herein shall be breached, the Collateral Agent may (but shall not be obligated to) do the same or cause it to be done or remedy any such breach, and may expend funds for such purpose; provided, however, that the Collateral Agent shall in no event be bound to inquire into the validity of any tax, Lien, imposition or other obligation which such Pledgor fails to pay or perform as and when required hereby and which such Pledgor does not contest in accordance with the provisions of the Indenture. Any and all amounts so expended by the Collateral Agent shall be paid by the Pledgors in accordance with the provisions of Section 7.6 of the Indenture. Neither the provisions of this Section 11.3 nor any action taken by the Collateral Agent pursuant to the provisions of this Section 11.3 shall prevent any such failure to observe any covenant contained in this Agreement nor any breach of representation or warranty from constituting an Event of Default. Each Pledgor hereby appoints the Collateral Agent its attorney-in-fact, with full power

-30-

and authority in the place and stead of such Pledgor and in the name of such Pledgor, or otherwise, from time to time to take any action and to execute any instrument consistent with the terms of the Indenture, this Agreement and the other Security Documents which the Collateral Agent may deem necessary to accomplish the purposes hereof (but the Collateral Agent shall not be obligated to and shall have no liability to such Pledgor or any third party for failure to so do or take action). The foregoing grant of authority is a power of attorney coupled with an interest and such appointment shall be irrevocable for the term hereof. Each Pledgor hereby ratifies all that such attorney shall lawfully do or cause to be done by virtue hereof.

SECTION 11.4. Continuing Security Interest; Assignment. This Agreement shall create a continuing security interest in the Pledged Collateral and shall (i) be binding upon the Pledgors, their respective successors and assigns and (ii) inure, together with the rights and remedies of the Collateral Agent hereunder, to the benefit of the Collateral Agent and the other Secured Parties and each of their respective successors, transferees and assigns. No other persons (including any other creditor of any Pledgor) shall have any interest herein or any right or benefit with respect hereto. Without limiting the generality of the foregoing clause (ii), any Secured Party may assign or otherwise transfer any indebtedness held by it secured by this Agreement to any other person, and such other person shall thereupon become vested with all the benefits in respect thereof granted to such Secured Party, herein or otherwise, subject however, to the provisions of the Indenture. Each of the Pledgors agrees that its obligations hereunder and the security interest created hereunder shall continue to be effective or be reinstated, as applicable, if at any time payment, or any part thereof, of all or any part of the Obligations is rescinded or must otherwise be restored by the Secured Party upon the bankruptcy or reorganization of any Pledgor or otherwise.

SECTION 11.5. Termination; Release. When all the Obligations have been paid in full in accordance with the provisions of the Indenture, this Agreement shall terminate. The Liens securing the Notes Obligations, will, automatically and without the need for any further action by any Person be released, in whole or in part, as provided in Section 8.1 of the Indenture. Upon termination of this Agreement the Pledged Collateral shall be released from the Lien of this Agreement. Upon such release or any release of Pledged Collateral or any part thereof in accordance with the provisions of the Indenture or the other Notes Documents, the Collateral Agent shall, upon the request and at the sole cost and expense of the Pledgors, assign, transfer and deliver to Pledgor, against receipt and without recourse to or warranty by the Collateral Agent except as to the fact that the Collateral Agent has not encumbered the released assets, such of the Pledged Collateral or any part thereof to be released (in the case of a release) as may be in possession of the Collateral Agent and as shall not have been sold or otherwise applied pursuant to the terms hereof, and, with respect to any other Pledged Collateral, proper documents and instruments (including UCC-3 termination financing statements or releases) acknowledging the termination hereof or the release of such Pledged Collateral, as the case may be.

SECTION 11.6. Modification in Writing. No amendment, modification, supplement, termination or waiver of or to any provision hereof, nor consent to any departure by any Pledgor therefrom, shall be effective unless the same shall be made in accordance with the terms of the Indenture and unless in writing and signed by the Collateral Agent. Any

-31-

amendment, modification or supplement of or to any provision hereof, any waiver of any provision hereof and any consent to any departure by any Pledgor from the terms of any provision hereof in each case shall be effective only in the specific instance and for the specific purpose for which made or given. Except where notice is specifically required by this Agreement or any other document evidencing the Obligations, no notice to or demand on any Pledgor in any case shall entitle any Pledgor to any other or further notice or demand in similar or other circumstances.

SECTION 11.7. Notices. Unless otherwise provided herein or in the Indenture, any notice or other communication herein required or permitted to be given shall be given in the manner and become effective as set forth in the Indenture, as to any Pledgor, addressed to it at the address of the Issuer set forth in the Indenture and as to the Collateral Agent, addressed to it at the address set forth in the Indenture, or in each case at such other address as shall be designated by such party in a written notice to the other party complying as to delivery with the terms of this Section 11.7.

SECTION 11.8. Governing Law, Consent to Jurisdiction and Service of Process; Waiver of Jury trial. Sections 12.7 and 12.8 of the Indenture are incorporated herein, mutatis mutandis, as if a part hereof.

SECTION 11.9. Severability of Provisions. Any provision hereof which is invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without invalidating the remaining provisions hereof or affecting the validity, legality or enforceability of such provision in any other jurisdiction.

SECTION 11.10. Execution in Counterparts. This Agreement and any amendments, waivers, consents or supplements hereto may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed and delivered shall be deemed to be an original, but all such counterparts together shall constitute one and the same agreement.

SECTION 11.11. Business Days. In the event any time period or any date provided in this Agreement ends or falls on a day other than a Business Day, then such time period shall be deemed to end and such date shall be deemed to fall on the next succeeding Business Day, and performance herein may be made on such Business Day, with the same force and effect as if made on such other day.

SECTION 11.12. No Credit for Payment of Taxes or Imposition. Such Pledgor shall not be entitled to any credit against the principal, premium, if any, or interest payable under the Indenture, and such Pledgor shall not be entitled to any credit against any other sums which may become payable under the terms thereof or hereof, by reason of the payment of any Tax on the Pledged Collateral or any part thereof.

SECTION 11.13. No Claims Against Collateral Agent. Nothing contained in this Agreement shall constitute any consent or request by the Collateral Agent, express or implied, for the performance of any labor or services or the furnishing of any materials or other

-32-

property in respect of the Pledged Collateral or any part thereof, nor as giving any Pledgor any right, power or authority to contract for or permit the performance of any labor or services or the furnishing of any materials or other property in such fashion as would permit the making of any claim against the Collateral Agent in respect thereof or any claim that any Lien based on the performance of such labor or services or the furnishing of any such materials or other property is prior to the Lien hereof.

SECTION 11.14. No Release. Nothing set forth in this Agreement or any other Notes Document, nor the exercise by the Collateral Agent of any of the rights or remedies hereunder, shall relieve any Pledgor from the performance of any term, covenant, condition or agreement on such Pledgor’s part to be performed or observed under or in respect of any of the Pledged Collateral or from any liability to any person under or in respect of any of the Pledged Collateral or shall impose any obligation on the Collateral Agent or any other Secured Party to perform or observe any such term, covenant, condition or agreement on such Pledgor’s part to be so performed or observed or shall impose any liability on the Collateral Agent or any other Secured Party for any act or omission on the part of such Pledgor relating thereto or for any breach of any representation or warranty on the part of such Pledgor contained in this Agreement, the Indenture or the other Notes Documents, or under or in respect of the Pledged Collateral or made in connection herewith or therewith. Anything herein to the contrary notwithstanding, neither the Collateral Agent nor any other Secured Party shall have any obligation or liability under any contracts, agreements and other documents included in the Pledged Collateral by reason of this Agreement, nor shall the Collateral Agent or any other Secured Party be obligated to perform any of the obligations or duties of any Pledgor thereunder or to take any action to collect or enforce any such contract, agreement or other document included in the Pledged Collateral hereunder. The obligations of each Pledgor contained in this Section 11.14 shall survive the termination hereof and the discharge of such Pledgor’s other obligations under this Agreement, the Indenture and the other Notes Documents.

SECTION 11.15. Obligations Absolute. All obligations of each Pledgor hereunder shall be absolute and unconditional irrespective of:

(i) any bankruptcy, insolvency, reorganization, arrangement, readjustment, composition, liquidation or the like of any other Pledgor;

(ii) any lack of validity or enforceability of the Indenture, any other Notes Document, or any other agreement or instrument relating thereto;

(iii) any change in the time, manner or place of payment of, or in any other term of, all or any of the Obligations, or any other amendment or waiver of or any consent to any departure from the Indenture, any other Notes Document or any other agreement or instrument relating thereto;

(iv) any pledge, exchange, release or non-perfection of any other collateral, or any release or amendment or waiver of or consent to any departure from any guarantee, for all or any of the Obligations;

-33-

(v) any exercise, non-exercise or waiver of any right, remedy, power or privilege under or in respect hereof, the Indenture, any other Notes Document except as specifically set forth in a waiver granted pursuant to the provisions of Section 11.4 hereof; or

(vi) any other circumstances which might otherwise constitute a defense (other than a defense of payment in full of the Obligations) available to, or a discharge of, any Pledgor.
