(d) Commodity Accounts. Each Lien Grantor covenants to enter into (and cause the relevant Commodity Intermediary to enter into) on or prior to April 30, 2006 (or such later date as to which the Collateral Agent may consent in its sole discretion) a Commodity Account Control Agreement in respect of each Pledged Commodity Account owned by it at such time and will deliver such Commodity Account Control Agreement to the Collateral Agent (which shall enter into the same) so long as Pledged Commodity Contracts with a fair market value in excess of $3,000,000 are credited to such account at such time unless such agreement has not been entered into solely other than as a result of any action or inaction on the part of such Lien Grantor; provided that the Lien Grantors shall only be required to comply with this covenant with respect to Commodity Accounts for which the relevant Commodity Intermediary’s jurisdiction is in the United States. Such Lien Grantor covenants that such Lien Grantor will thereafter cause, as promptly as practicable, each Pledged Commodity Contract owned by it with a fair market value in excess of $3,000,000 to be carried at all times in a Controlled Commodity Account; provided that the Lien Grantors shall not be so obligated if the jurisdiction of the Commodity Intermediary for the Commodity Account in which such Commodities Contract is carried is not in the United States.

(e) Perfection as to Certificated Securities. Such Lien Grantor represents and warrants that, at the time that such Lien Grantor delivers the certificate representing any Pledged Certificated Security owned by it to the Collateral Agent in the United States and complies with Section 6(j) in connection with such delivery, (i) the Transaction Lien on such Pledged Certificated Security will be perfected, subject to no prior Liens or rights of others, and (ii) the Collateral Agent will have Control of such Pledged Certificated Security.

(f) Perfection as to Uncertificated Securities. Such Lien Grantor represents and warrants that, at the time that such Lien Grantor, the Collateral Agent and the U.S. issuer of any Pledged Uncertificated Security owned by such Lien Grantor enter into an Issuer Control Agreement with respect thereto, (i) the Transaction Lien on such Pledged Uncertificated Security will be perfected, subject to no prior Liens or rights of others and (ii) the Collateral Agent will have Control of such Pledged Uncertificated Security.

(g) Perfection as to Security Entitlements. Such Lien Grantor represents and warrants that, at the time that the Financial Asset underlying any Pledged Security Entitlement owned by such Lien Grantor is credited to the applicable Controlled Securities Account, (i) the Transaction Lien on such Pledged Security Entitlement will be perfected, subject to no prior Liens or rights of others (except Liens and rights of the relevant Securities Intermediary that are Permitted Liens or rights of set-off) other than Liens existing on the date of this Agreement that are Permitted Liens and (ii) the Collateral Agent will have Control of such Pledged Security Entitlement; provided that NNI shall be deemed to have made this representation and warranty only with respect to Securities Accounts for which the relevant Securities Intermediary’s jurisdiction is in the United States.

(h) Perfection as to Commodity Accounts. Each Lien Grantor covenants that so long as any Commodity Account is subject to a Commodity Account Control Agreement (i) the Transaction Liens on such Pledged Commodity Account and all Pledged Commodity Contracts carried therein will be perfected, subject to no prior Liens or rights of others (except Liens and rights of the relevant Commodity Intermediary permitted by such Commodity Account Control Agreement) other than Liens existing on the date of this Agreement that are Permitted Liens and the Collateral Agent will have Control of such Commodity Account and all Commodity Contracts carried therein from time to time; provided that the Lien Grantors shall be deemed to have made this representation and warranty only with respect to Commodity Accounts for which the relevant Commodity Intermediary’s jurisdiction is in the United States.

(i) Agreement as to Applicable Jurisdiction. Each Lien Grantor covenants that in respect of all Pledged Security Entitlements owned by such Lien Grantor, and all Securities Accounts to which the related Financial Assets are credited, the Securities Intermediary’s jurisdiction (determined as provided in UCC Section 8-110(e)) will at all times be located in the United States. In respect of all Commodity Contracts owned by such Lien Grantor and all Commodity Accounts in which such Commodity Contracts are carried, the Commodity Intermediary’s jurisdiction (determined as provided in UCC Section 9-305(b)) will at all times be located in the United States.

(j) Delivery of Pledged Certificates. Each Lien Grantor covenants that all Pledged Certificates, when delivered to the Collateral Agent, will be in suitable form for transfer by delivery, or accompanied by duly executed instruments of transfer or assignment in blank, all in form and substance satisfactory to the Collateral Agent.

Section 7. Controlled Deposit Accounts. Each Lien Grantor covenants as follows:

(a) Such Lien Grantor covenants that, no later than April 30, 2006 (or such later date as to which the Collateral Agent may consent in its sole discretion), it will deliver to the Collateral Agent duly executed Deposit Account Control Agreements with respect to each account listed on Schedule 5. Each Lien Grantor agrees that the Deposit Accounts listed on Schedule 5 are the principal cash management Deposit Accounts of the Lien Grantors with Depositary Banks’ whose jurisdictions are in the United States. Upon the occurrence and during the continuance of a Specified Event of Default, all cash owned by such Lien Grantor (other than cash which is subject to a Lien incurred in reliance on Section 19(e)) will be deposited, upon or promptly after the receipt thereof, in one or more Controlled Deposit Accounts. Each Controlled Deposit Account will be operated as provided in Section 9.

(b) Such Lien Grantor covenants that, in respect of each Controlled Deposit Account, the Depositary Bank’s jurisdiction (determined as provided in UCC Section 9-304) will at all times be a jurisdiction in which Article 9 of the Uniform Commercial Code (including without limitation the UCC) is in effect.

(c) Such Lien Grantor covenants that, so long as the Collateral Agent has Control of a Controlled Deposit Account, the Transaction Lien on such Controlled Deposit Account will be perfected, subject to no prior Liens or rights of others (except the Depositary Bank’s rights of set-off and right to deduct its normal operating charges and fees and any uncollected funds previously credited thereto) other than Liens existing on the date of this Agreement that are Permitted Liens.

(d) Such Lien Grantor covenants that, if such Lien Grantor opens a new Deposit Account with a Depositary Bank whose jurisdiction is in the United States (determined as provided in UCC Section 9-304) that it intends to use as a principal cash management account for the NNC Companies (taken as a whole) as determined by such Lien Grantor in good faith, such Lien Grantor shall promptly notify the Collateral Agent thereof and will deliver to the Collateral Agent a duly executed Deposit Account Control Agreement with respect thereto; provided

that such Lien Grantor shall not be deemed in breach of this covenant if any such agreement shall fail to be finalized solely other than as a result of any action or inaction on the part of such Lien Grantor.

(e) Except as permitted by Section 19, such Lien Grantor shall not transfer cash out of any Controlled Deposit Account for the principal purpose of preventing the Collateral Agent from having a perfected lien in such cash (it being understood that nothing herein shall prevent any Lien Grantor from withdrawing cash from any Controlled Deposit Account for any other purpose).

Section 8. Cash Collateral Accounts. (a) If an Event of Default shall have occurred and is continuing and the Required Secured Lenders shall have so instructed the Collateral Agent, the Collateral Agent will establish with respect to each Lien Grantor an account (its “Cash Collateral Account”), in the name and under the exclusive control of the Collateral Agent, subject to subsection 8(d). Each Cash Collateral Account will be operated as provided in this Section 8 and Section 9.

(b) The Collateral Agent shall deposit the following amounts, as and when received by it, in each Lien Grantor’s Cash Collateral Account: each amount required to be deposited therein by any provision of any Credit Agreement or other Loan Document referred to therein, each Cash Distribution required by Section 12 to be deposited therein and each amount realized or otherwise received by the Collateral Agent with respect to assets of such Lien Grantor upon any exercise of remedies pursuant to any Security Document upon the occurrence and during the continuance of (x) with respect to Illiquid Collateral, an Event of Default and (y) with respect to Liquid Collateral, a Specified Event of Default.

(c) The Collateral Agent shall maintain such records and/or establish such sub-accounts as shall be required to enable it to identify the amounts held in each Cash Collateral Account from time to time pursuant to Section 8(b).

(d) Unless an Event of Default shall have occurred and is continuing and the Required Secured Lenders shall have instructed the Collateral Agent to stop withdrawing amounts from the Cash Collateral Accounts pursuant to this subsection 8(d), any Cash Distributions or other amounts deposited in the Cash Collateral Account shall, at the relevant Lien Grantor’s request, be withdrawn and applied to pay Secured Obligations that are then due and payable.

Section 9. Operation of Collateral Accounts. (a) All Cash Distributions received with respect to assets held in any Collateral Account shall be deposited therein promptly upon receipt thereof.

(b) Funds held in any Controlled Securities Account may, until withdrawn, be invested and reinvested as the relevant Lien Grantor shall determine from time to time; provided that, if a Specified Event of Default shall have occurred and is continuing, the Collateral Agent may select short term cash equivalents (and the Collateral Agent shall not be liable to any Lien Grantor or any Secured Party for any loss as a result of any disposition of any such short term cash equivalent prior to maturity ).

(c) So long as no Specified Event of Default shall have occurred and is continuing, funds held in any Controlled Deposit Account or Cash Collateral Account may, until withdrawn, be invested and reinvested as the relevant Lien Grantor shall determine from time to time; provided that (i) if a Specified Event of Default shall have occurred and is continuing, the Collateral Agent may select short term cash equivalents in which any available funds may be invested and (ii) if such amounts are to be held in a Securities Account, either (x) the Collateral Agent is the Entitlement Holder with respect to such amounts or (y) the relevant Entitlement Holder and the relevant Securities Intermediary shall have theretofore entered into a Securities Account Control Agreement with respect to such Securities Account and delivered it to the Collateral Agent (which shall enter into the same).

(d) With respect to each Collateral Account (except a Cash Collateral Account, as to which Section 8 applies), the Collateral Agent will, if requested by the applicable Lien Grantor, instruct the relevant Securities Intermediary or Depositary Bank that the relevant Lien Grantor may withdraw, or direct the disposition of, funds held therein unless and until the Collateral Agent rescinds such instruction. The Collateral Agent will not rescind such instructions unless a Specified Event of Default shall have occurred and is continuing.

(e) So long as a Specified Event of Default shall have occurred and is continuing, no Lien Grantor will cause funds to be transferred from a Collateral Account to any other account owned by an NNC Company unless such other account is a Collateral Account.

(f) If a Specified Event of Default shall have occurred and is continuing, the Collateral Agent may (i) retain, or instruct the relevant Securities Intermediary or Depositary Bank to retain, all cash and investments then held in any Collateral Account, (ii) liquidate, or instruct the relevant Securities Intermediary or Depositary Bank to liquidate, any or all investments held therein and/or (iii) withdraw any amounts held therein and apply such amounts as provided in Section 14.

(g) If a Specified Event of Default shall have occurred and is continuing, and immediately available cash on deposit in any Collateral Account is not sufficient to make any distribution or withdrawal to be made pursuant hereto, the Collateral Agent will cause to be liquidated, as promptly as practicable, such investments held in or credited to such Collateral Account as shall be required to obtain sufficient cash to make such distribution or withdrawal and, notwithstanding any other provision hereof, such distribution or withdrawal shall not be made until such liquidation has taken place.

Section 10. Transfer of Record Ownership. (a) At any time when an Event of Default shall have occurred and is continuing, the Collateral Agent may (and to the extent that action by it is required, the relevant Lien Grantor, if directed to do so by the Collateral Agent, will as promptly as practicable): cause each of the Pledged Certificated Securities (or any portion thereof specified in such direction) to be transferred of record into the name of the Collateral Agent or its nominee. Promptly upon receiving any such direction, the Collateral Agent will notify each relevant Lien Grantor thereof, and from time to time thereafter such Lien Grantor will take any and all actions reasonably requested by the Collateral Agent to facilitate compliance with this subsection 10(a).

(b) Communications after Transfer of Record Ownership. The Collateral Agent will promptly give to the relevant Lien Grantor copies of any notices and other communications received by the Collateral Agent with respect to Pledged Certificated Securities registered in the name of the Collateral Agent or its nominee.

Section 11. Right to Vote Securities. (a) Unless (i) (x) with respect to any Pledged Security not credited to a Securities Account other than any Uncertificated Security representing shares in a money market fund, an Event of Default shall have occurred and is continuing or (y) with respect to any Pledged Security credited to a Securities Account and any Financial Asset underlying any Pledged Security Entitlement owned by it and any Uncertificated Securities representing shares in a money market fund, a Specified Event of Default shall have occurred and is continuing and (ii) the Collateral Agent shall have provided notice to the Lien Grantor of the Collateral Agent’s election to terminate the right of such Lien Grantor to exercise such rights, each Lien Grantor will have the right, from time to time, to vote and to give consents, ratifications and waivers with respect to any Pledged Security owned by it and the Financial Asset underlying any Pledged Security Entitlement owned by it, and the Collateral Agent will, upon receiving a written request from such Lien Grantor, promptly deliver to such Lien Grantor or as specified in such request such proxies, powers of attorney, consents, ratifications and waivers in respect of any such Pledged Security that is registered in the name of the Collateral Agent or its nominee or any such Pledged Security Entitlement as to which the Collateral Agent or its nominee is the Entitlement Holder, in each case as shall be specified in such request and be in form and substance reasonably satisfactory to the Collateral Agent. Unless (i)(x) with respect to any Pledged Security not credited to a Securities Account other than any Uncertificated Security representing shares in a money market fund, an Event of Default shall have occurred and is continuing or (y) with respect to any Pledged Security credited to a Securities Account and any Financial Asset underlying any Pledged Security Entitlement owned by it and any Uncertificated Securities representing shares in a money market fund, a Specified Event of Default shall have occurred and is continuing and (ii) the Collateral Agent shall have provided notice to the Lien Grantor of the Collateral Agent’s election to terminate the right of such Lien Grantor to exercise such rights, the Collateral Agent will have no right to take any action which the owner of a Pledged Security, Pledged Partnership Interest or Pledged LLC Interest is entitled to take with respect thereto, except the right to receive payments and other distributions to the extent provided herein.

(b) If (i)(x) with respect to any Pledged Security not credited to a Securities Account other than any Uncertificated Security representing shares in any money market fund, an Event of Default shall have occurred and is continuing or (y) with respect to any Pledged Security credited to a Securities Account and any Financial Asset

underlying any Security Entitlement owned by it and any Uncertificated Securities consisting of shares in a money market fund , a Specified Event of Default shall have occurred and is continuing and (ii) the Collateral Agent shall have provided notice to the Lien Grantor of the Collateral Agent’s election to terminate the right of such Lien Grantor to exercise such rights,, the Collateral Agent will have the right to the extent permitted by law (and, in the case of a Pledged Security, Pledged Partnership Interest or Pledged LLC Interest, by the relevant partnership agreement, limited liability company agreement, operating agreement or other governing document) to vote, to give consents, ratifications and waivers and to take any other action with respect to the Pledged Investment Property, the other Pledged Equity Interests (if any) and the Financial Assets underlying the Pledged Security Entitlements, with the same force and effect as if the Collateral Agent were the absolute and sole owner thereof, and each Lien Grantor will take all such action as the Collateral Agent may reasonably request from time to time to give effect to such right.

Section 12. Certain Cash Distributions. Cash Distributions with respect to assets held in a Collateral Account shall be deposited and held therein, or withdrawn therefrom, as provided in Section 8 and Section 9. If a Specified Event of Default shall have occurred and is continuing, Cash Distributions (other than in amounts less than $3,000,000) with respect to any Pledged Equity Interest that is not held in a Collateral Account (whether held in the name of a Lien Grantor or in the name of the Collateral Agent or its nominee) shall be deposited, as soon as practicable upon receipt thereof, in a Controlled Deposit Account of the relevant Lien Grantor if such account exists at such time and otherwise, turned over to the Collateral Agent.

Section 13. Remedies upon Event of Default or Specified Event of Default. (a) If (x) with respect to Illiquid Collateral, an Event of Default shall have occurred and is continuing or (y) with respect to Liquid Collateral, a Specified Event of Default shall have occurred and is continuing, the Collateral Agent may exercise (or cause its sub-agents to exercise) any or all of the remedies available to it (or to such sub-agents) under the Security Documents with respect to Illiquid Collateral or Liquid Collateral, as applicable. Without limiting the generality of the foregoing, if (x) with respect to Illiquid Collateral, an Event of Default shall have occurred and is continuing or (y) with respect to Liquid Collateral, a Specified Event of Default shall have occurred and is continuing, the Collateral Agent may exercise on behalf of the Secured Parties all the rights of a secured party under the UCC (whether or not in effect in the jurisdiction where such rights are exercised) with respect to Illiquid Collateral or Liquid Collateral, as applicable, and, in addition, the Collateral Agent may, if a Specified Event of Default shall have occurred and is continuing, without being required to give any notice, except as herein provided or as may be required by mandatory provisions of law, withdraw all cash held in the Collateral Accounts and apply such cash as provided in Section 14 and, if there shall be no such cash or if such cash shall be insufficient to pay all the Secured Obligations in full, sell, lease, license or otherwise dispose of (x) if a Event of Default has occurred and is continuing, the Illiquid Collateral or any part thereof and (y) if Specified Event of Default shall have occurred and is continuing, the Liquid Collateral or any part thereof. Notice of any such sale or other disposition shall be given to the relevant Lien Grantor(s) as required by Section 16.

(b) Without limiting the generality of the foregoing, if a Specified Event of Default shall have occurred and is continuing: the Collateral Agent may license or sublicense, whether general, special or otherwise, and whether on an exclusive or non-exclusive basis, any Pledged Intellectual Property (including any Pledged Recordable Intellectual Property) throughout the world for such term or terms, on such conditions and in such manner as the Collateral Agent shall in its sole discretion determine; provided that the Collateral Agent shall notify the relevant Lien Grantor of any license or sublicenses so granted (but failure to give such notice shall not effect the validity of such license) and that such licenses or sublicenses do not conflict with any existing license or applicable law; the Collateral Agent may (without assuming any obligation or liability thereunder), at any time and from time to time, in its sole and reasonable discretion, enforce (and shall have the exclusive right to enforce) against any licensee or sublicensee all rights and remedies of any Lien Grantor in, to and under any of its Pledged Intellectual Property and take or refrain from taking any action under any thereof, and each Lien Grantor releases the Collateral Agent and each other Secured Party from liability for, and agrees to hold the Collateral Agent and each other Secured Party free and harmless from and against any claims and reasonable expenses arising out of, any lawful action so taken or omitted to be taken with respect thereto, except for claims and reasonable expenses arising from the Collateral Agent’s or such Secured Party’s gross negligence or willful misconduct; and upon request by the Collateral Agent (which shall not be construed as implying any limitation on rights or powers), each Lien Grantor will execute and deliver to the Collateral Agent a power of attorney, in form and substance satisfactory to the Collateral Agent, for the implementation of any sale, lease, license or other disposition of any of such Lien Grantor’s

Pledged Intellectual Property or any action related thereto. In connection with any such disposition, but subject to any confidentiality restrictions imposed on such Lien Grantor in any license or similar agreement, such Lien Grantor will supply to the Collateral Agent its know-how and expertise relating to the relevant Intellectual Property or the products or services made or rendered in connection with such Intellectual Property, and its customer lists and other records relating to such Intellectual Property and to the distribution of said products or services.

Section 14. Application of Proceeds. (a) The Collateral Agent may (i) if a Specified Event of Default shall have occurred and is continuing, apply any cash held in the Collateral Accounts and (ii) if (x) with respect to Illiquid Collateral, an Event of Default shall have occurred and is continuing or (y) with respect to Liquid Collateral, a Specified Event of Default shall have occurred and is continuing, apply the proceeds of any sale or other disposition of all or any part of the Illiquid Collateral or Liquid Collateral, as applicable, in either case in the following order of priorities:

(1) to pay the expenses of such sale or other disposition, including reasonable compensation to agents of and counsel for the Collateral Agent, and all reasonable expenses, liabilities and advances incurred or made by the Collateral Agent in connection with the Security Documents, and any other amounts then due and payable to the Collateral Agent pursuant to Section 15 or any amounts owing to the Indenture Trustee under Section 5.05 of the 1988 Indenture, or any amounts owing to EDC under the EDC Support Facility and consisting of reimbursement obligations with respect to fees and expenses incurred by EDC;

(2) to pay the due and unpaid principal, face amount or termination amount of the Secured Obligations ratably, on the basis of the principal or face amount of such Secured Obligations (or, with respect to Contingent Secured Obligations, provide for the payment thereof pursuant to Section 14(b)), until payment in full of the principal of all Secured Obligations shall have been made (or, with respect to Contingent Secured Obligations, so provided for);

(3) to pay ratably the due and unpaid interest accrued on the Secured Obligations in accordance with the provisions of the applicable Secured Agreement, as applicable;

(4) to pay all other due and unpaid Secured Obligations and all due and unpaid commitment fees and participation fees under each Credit Agreement ratably (or, with respect to Contingent Secured Obligations, provide for the payment thereof pursuant to Section 14(b)), until payment in full of all such other Secured Obligations and fees shall have been made (or, with respect to Contingent Secured Obligations, so provided for); and

(5) to pay to the relevant Lien Grantor, or as a court of competent jurisdiction may direct, any surplus then remaining from the proceeds of the Collateral owned by it;

provided that Collateral owned by any Subsidiary Lien Grantor and any proceeds thereof shall be applied pursuant to the foregoing clauses (1), (2), (3) and (4) of this Section 14 to the Secured Obligations of such Subsidiary Lien Grantor only up to an aggregate amount equal to the largest amount that would not render such application of Collateral or proceeds subject to avoidance under Section 548 of the United States Bankruptcy Code or any comparable provisions of applicable law. The Collateral Agent may make such distributions hereunder in cash or in kind or, on a ratable basis, in any combination thereof.

(b) If at any time any portion of any monies collected or received by the Collateral Agent would, but for the provisions of this Section 14(b), be payable pursuant to Section 14 in respect of a Contingent Secured Obligation, the Collateral Agent shall not apply any monies to pay such Contingent Secured Obligation but shall

instead (x) notify the holder of such Contingent Secured Obligation and (y) with respect to the holder of such Contingent Secured Obligations excluding the holder of any Bond Obligation, request the holder thereof, at least 10 days before each proposed distribution hereunder, to notify the Collateral Agent as to the maximum amount of such Contingent Secured Obligation if then ascertainable (e.g., in the case of a letter of credit, the maximum amount available for subsequent drawings thereunder). If the holder of such Contingent Secured Obligation (excluding the holder of any Bond Obligation) does not notify the Collateral Agent of the maximum ascertainable amount thereof at least two Business Days before such distribution, such holder will not be entitled to share in such distribution. If such holder does so notify the Collateral Agent as to the maximum ascertainable amount thereof, or if such holder is the holder of any Bond Obligation (regardless of whether such holder has provided any notice to the Collateral Agent), the Collateral Agent will allocate to such holder a portion of the monies to be distributed in such distribution, calculated as if such Contingent Secured Obligation were outstanding in such maximum ascertainable amount. However, the Collateral Agent will not apply such portion of such monies to pay such Contingent Secured Obligation, but instead will hold such monies and invest such monies in short term cash equivalents selected by the Collateral Agent. All such monies and short term cash equivalents and all proceeds thereof will constitute Collateral hereunder, but will be subject to distribution in accordance with this Section 14(b) rather than Section 14(a). The Collateral Agent will hold all such monies and short term cash equivalents and the net proceeds thereof in trust until all or part of such Contingent Secured Obligation becomes a Non-Contingent Secured Obligation, whereupon the Collateral Agent at the request of the relevant Secured Party will apply the amount so held in trust to pay such Non-Contingent Secured Obligation; provided that, if the other Secured Obligations theretofore paid pursuant to the same clause of Section 14(a) (i.e., clause (2) or (3)) were not paid in full, the Collateral Agent will apply the amount so held in trust to pay the same percentage of such Non-Contingent Secured Obligation as the percentage of such other Secured Obligations theretofore paid pursuant to the same clause of Section 14(a). If (i) the holder of such Contingent Secured Obligation shall advise the Collateral Agent that no portion thereof remains in the category of a Contingent Secured Obligation and (ii) the Collateral Agent still holds any amount held in trust pursuant to this Section 14(b) in respect of such Contingent Secured Obligation (after paying all amounts payable pursuant to the preceding sentence with respect to any portions thereof that became Non-Contingent Secured Obligations), such remaining amount will be applied by the Collateral Agent in the order of priorities set forth in Section 14(a).

(c) With respect to any Bond Obligation, whether or not a Contingent Secured Obligation, including, without limitation, the principal outstanding of and interest on such Bond Obligation, an amount (the “Determined Amount”) with respect to such Bond Obligation shall be required to be paid or held by the Collateral Agent with respect to each of Sections 14(a)(2), 14(a)(3) and 14(a)(4) (each, a “Level”) equal to (x) the Ratio multiplied by (y) the sum of (A) the proceeds of any sale or other disposition of Collateral that are, in fact, being applied by the Collateral Agent to amounts owed under the Credit Agreements at the applicable Level, plus (B) the proceeds of such Collateral proposed to be held by the Collateral Agent pursuant to Section 14(b) to cover the Contingent Secured Obligations relating to the Credit Agreements at such Level in accordance with Section 14(b). Notwithstanding the foregoing, if the amount to be applied to the Bond Obligations at any Level would be greater if the Ratio were calculated by reference to a Secured Obligation (other than the principal under the Credit Agreements) that constitutes “Funded Debt” under the 1988 Indenture, such Secured Obligation shall be used in order to determine the amount to be applied to the Bond Obligations at such Level. Section 14 of this Agreement (including this Section 14(c)) is intended to comply with the equal and ratable negative pledge provisions of the 1988 Indenture and shall be construed to give effect to such intention. The Collateral Agent shall be obligated to offer to pay to the Indenture Trustee any portion of the Determined Amounts that are, in fact, due and payable at such time as such Determined Amounts are calculated, and the Collateral Agent shall deposit any remaining portion of such Determined Amounts and any amounts not accepted by the Indenture Trustee in a segregated account solely for the benefit of the holders of the Bond Obligations (and all amounts on deposit in such account shall be invested in short term cash equivalents).

(d) In making the payments and allocations required by this Section 14, the Collateral Agent may rely upon information supplied to it pursuant to Section 18(e). All distributions made by the Collateral Agent pursuant to this Section 14 shall be final (except in the event of manifest error) and the Collateral Agent shall have no duty to inquire as to the application by any Secured Party of any amount distributed to it.

Section 15. Fees and Expenses. Each Lien Grantor will forthwith upon demand pay to the Collateral Agent: the amount of any taxes that the Collateral Agent may have been required to pay by reason of the Transaction Liens or to free any Collateral from any other Lien thereon; the amount of any and all reasonable

out-of-pocket expenses, including transfer taxes and reasonable fees and expenses of outside counsel and other experts, that the Collateral Agent may incur (except (x) so long as no Specified Event of Default shall have occurred and is continuing, any filing fees with respect to Intellectual Property Filings other than with respect to Material Recordable Intellectual Property and (y) Intellectual Property Filings with respect to Trademarks which are not Material Recordable Intellectual Property) in connection with (i) the administration or enforcement of the Security Documents, including such reasonable out-of-pocket expenses as are incurred to preserve the value of the Collateral or the validity, perfection, rank or value of any Transaction Lien, (ii) the collection, sale or other disposition of any Collateral or (iii) the exercise by the Collateral Agent of any of its rights or powers under the Security Documents; the amount of any fees that the Borrower shall have agreed in writing to pay to the Collateral Agent and that shall have become due and payable in accordance with such written agreement and the amount required to indemnify the Collateral Agent for, or hold it harmless and defend it against, any loss, liability or expense (including the reasonable fees and out-of-pocket expenses of its counsel and any experts or sub-agents appointed by it hereunder) incurred or suffered by the Collateral Agent in connection with the Security Documents (except (x) so long as no Specified Event of Default shall have occurred and is continuing, any filing fees with respect to or arising in connection with Intellectual Property Filings other than with respect to Material Recordable Intellectual Property and (y) Intellectual Property Filings with respect to Trademarks which are not Material Recordable Intellectual Property), except to the extent that such loss, liability or expense arises from the Collateral Agent’s gross negligence or willful misconduct or a breach of any duty that the Collateral Agent has under this Agreement (after giving effect to Sections 17 and 18). Any such amount not paid to the Collateral Agent as soon as practicable will bear interest for each day thereafter until paid at a rate per annum equal to the sum of 2% plus the highest rate applicable to the base rate loans under the 2006 Credit Agreement, if it shall not have been terminated, or 2% plus the overnight federal funds rate if the 2006 Credit Agreement shall have been terminated. If any transfer tax, documentary stamp tax or other tax is payable in connection with any transfer or other transaction provided for in the Security Documents, the Lien Grantors will pay such tax and provide any required tax stamps to the Collateral Agent or as otherwise required by law.

Section 16. Authority to Administer Collateral. Each Lien Grantor irrevocably appoints the Collateral Agent its true and lawful attorney, with full power of substitution, in the name of such Lien Grantor, any Secured Party or otherwise, for the sole use and benefit of the Secured Parties, but at NNL’s expense, to the extent permitted by law to exercise, at any time and from time to time while (x) an Event of Default with respect to Illiquid Collateral and (y) a Specified Event of Default with respect to Liquid Collateral shall have occurred and is continuing, all or any of the following powers with respect to all or any of such Lien Grantor’s Collateral:

(a) to demand, ▇▇▇ for, collect, receive and give acquittance for any and all monies due or to become due upon or by virtue thereof;

(b) to settle, compromise, compound, prosecute or defend any action or proceeding with respect thereto;

(c) to sell, lease, license or otherwise dispose of the same or the proceeds or avails thereof, as fully and effectually as if the Collateral Agent were the absolute owner thereof; and

(d) to extend the time of payment of any or all thereof and to make any allowance or other adjustment with reference thereto;

provided that, except in the case of Collateral that is perishable or threatens to decline speedily in value or is of a type customarily sold on a recognized market, the Collateral Agent will give the relevant Lien Grantor at least ten days’ prior written notice of the time and place of any public sale thereof or the time after which any private sale or other intended disposition thereof will be made. Any such notice shall (i) contain the information specified in UCC Section 9-613, (ii) be Authenticated and (iii) be sent to the parties required to be notified pursuant to UCC Section 9-611(c); provided that, if the Collateral Agent fails to comply with this sentence in any respect, its liability for such failure shall be limited to the liability (if any) imposed on it as a matter of law under the UCC.

Section 17. Limitation on Duty in Respect of Collateral. Beyond the exercise of reasonable care in the custody and preservation thereof, the Collateral Agent will have no duty as to any Collateral in its possession or control or in the possession or control of any sub-agent or bailee selected by it in good faith or any income therefrom or as to the preservation of rights against prior parties or any other rights pertaining thereto. The Collateral Agent

will be deemed to have exercised reasonable care in the custody and preservation of the Collateral in its possession or Control if such Collateral is accorded treatment substantially equal to that which it accords its own property, and will not be liable or responsible for any loss or damage to any Collateral, or for any diminution in the value thereof, by reason of any act or omission of any sub-agent or bailee selected by the Collateral Agent in good faith, except to the extent that such liability arises from the Collateral Agent’s gross negligence or willful misconduct.

Section 18. General Provisions Concerning the Collateral Agent. (a) Authority. Each Secured Party hereby appoints JPMorgan Chase Bank, N.A. to serve as Collateral Agent hereunder. The Collateral Agent is authorized to take such actions and to exercise such powers as are delegated to the Collateral Agent by the terms of the Security Documents, together with such actions and powers as are reasonably incidental thereto. The Collateral Agent agrees to hold that part of the Collateral that is in its possession or control (or in the possession or control of its agents or bailees), to the extent that possession thereof is taken to perfect a Lien thereon under the UCC for the benefit of and on behalf of the Secured Parties for the purpose of perfecting the security interest granted under the Security Documents, subject to the terms of this Section 18.

(b) Rights and Powers as a Secured Party. The bank serving as the Collateral Agent shall, in its capacity as a Secured Party, have the same rights and powers as any other Secured Party and may exercise the same as though it were not the Collateral Agent. Such bank and its affiliates may accept deposits from, lend money to and generally engage in any kind of business with any NNC Company as if it were not the Collateral Agent hereunder.

(c) Limited Duties and Responsibilities. The Collateral Agent shall not have any duties or obligations under the Security Documents except those expressly set forth therein. Without limiting the generality of the foregoing, (i) the Collateral Agent shall not be subject to any fiduciary or other implied duties, regardless of whether an Event of Default has occurred and is continuing, (ii) the Collateral Agent shall not be required to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers (x) which are expressly contemplated by the Security Documents and (y) which it has been instructed to exercise by the Required Secured Lenders and (iii) except as expressly set forth in the Loan Documents to which it is party, the Collateral Agent shall not have any duty to disclose, and shall not be liable for any failure to disclose, any information relating to any NNC Company that is communicated to or obtained by the Collateral Agent or any of its affiliates in any capacity. The Collateral Agent shall not be liable for any action taken or not taken by it with the consent or at the request of the Required Secured Lenders or in the absence of its own gross negligence or willful misconduct. The Collateral Agent shall not be responsible for the existence, genuineness or value of any Collateral or for the validity, perfection, priority or enforceability of any Transaction Lien, whether impaired by operation of law or by reason of any action or omission to act on its part under the Security Documents, in either case absent its own gross negligence or willful misconduct. The Collateral Agent shall be deemed not to have knowledge of any Event of Default unless and until written notice thereof is given to the Collateral Agent by any Lien Grantor or a Secured Party, and the Collateral Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with any Security Document, (ii) the contents of any certificate, report or other document delivered thereunder or in connection therewith other than by it, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth in any Security Document, (iv) the validity, enforceability, effectiveness or genuineness of any Security Document or any other agreement, instrument or document or (v) the satisfaction of any condition set forth in any Security Document.

(d) Authority to Rely on Certain Writings, Statements and Advice. The Collateral Agent shall be entitled to rely on, and shall not incur any liability for relying on, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be genuine and to have been signed or sent by the proper Person. The Collateral Agent also may rely on any statement made to it orally or by telephone and believed by it to be made by the proper Person, and shall not incur any liability for relying thereon. The Collateral Agent may consult with legal counsel (who may be counsel for any NNC Company), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountant or expert. The Collateral Agent may rely conclusively on advice from the Indenture Trustee as to whether at any time the maturity of the 2023 Notes has been accelerated.

(e) Sub-Agents and Related Parties. The Collateral Agent may perform any of its duties and exercise any of its rights and powers through one or more sub-agents appointed by it in good faith. The Collateral Agent and any such sub-agent may perform any of its duties and exercise any of its rights and powers through its directors, officers,

employees and agents (the “Related Parties”). The exculpatory provisions of Section 17 and this Section 18 shall apply to any such sub-agent and to the Related Parties of the Collateral Agent and any such sub-agent.

(f) Information as to Secured Obligations and Actions by Secured Parties. For all purposes of the Security Documents, including determining the amounts of the Secured Obligations and whether a Secured Obligation is a Contingent Secured Obligation or not, or whether any action has been taken under any Secured Agreement, the Collateral Agent will be entitled to rely on information from (i) its own records for information as to the Lenders, the Bank Obligations and actions taken by the Lenders, (ii) the Indenture Trustee for information as to the Bond Obligations and actions taken by the holders thereof, (iii) EDC for information as to the EDC Support Facility Obligations and actions taken by the holders thereof, (iv) any Secured Party for information as to its Secured Obligations and actions taken by it, to the extent that the Collateral Agent has not obtained such information from the foregoing sources and (v) NNI, to the extent that the Collateral Agent has not obtained information from the foregoing sources.

(g) The Collateral Agent may refuse to act on any notice, consent, direction or instruction from any Secured Parties or any agent, trustee or similar representative thereof that, in the Collateral Agent’s opinion, (i) is contrary to law or the provisions of any Security Document or (ii) may expose the Collateral Agent to liability (unless the Collateral Agent shall have been indemnified, to its reasonable satisfaction, for such liability by the Secured Parties that gave such notice, consent, direction or instruction).

(h) Resignation; Successor Collateral Agent. Subject to the appointment and acceptance of a successor Collateral Agent as provided in this subsection 18(h), the Collateral Agent may resign at any time by notifying EDC, the Lenders and NNI. Upon any such resignation, the Required Secured Lenders shall have the right to appoint a successor Collateral Agent reasonably acceptable to NNI. If no successor shall have been so appointed by the Required Secured Lenders and shall have accepted such appointment within 30 days after the retiring Collateral Agent gives notice of its resignation, then the retiring Collateral Agent may, on behalf of the Secured Parties, appoint a successor Collateral Agent reasonably acceptable to NNI, which shall be a bank with an office in New York, New York, or an affiliate of any such bank. Upon acceptance of its appointment as Collateral Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Collateral Agent hereunder, and the retiring Collateral Agent shall be discharged from its duties and obligations hereunder. The fees payable by NNI to a successor Collateral Agent shall be the same as those payable to its predecessor unless otherwise agreed by NNI and such successor. After the Collateral Agent’s resignation hereunder, the provisions of this Section 18 and Section 17 shall continue in effect for the benefit of such retiring Collateral Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring Collateral Agent was acting as Collateral Agent.

Section 19. Termination of Transaction Liens; Release of Collateral. (a) The Transaction Liens granted by each Lien Grantor shall terminate on the Bank Termination Date.

(b) Concurrently with any sale, exchange, assignment, lease, Financing Lease or other disposition of any item of Collateral by any Lien Grantor (except a lease or a sale, exchange, assignment, Financing Lease or other disposition to another Lien Grantor whose “Secured Obligations” hereunder include “Secured Obligations” of the Lien Grantor effecting such sale or other disposition) not expressly prohibited by the 2006 Credit Agreement or by this Agreement, the Transaction Liens on the assets sold or otherwise disposed of (but not in any Proceeds arising from such sale or other disposition) will cease immediately without any action by the Collateral Agent or any other Secured Party; provided that no Specified Event of Default shall have occurred and is continuing or would result therefrom.

(c) Upon any Collateral of any Lien Grantor becoming Transferred Receivables or Related Transferred Rights, the Transaction Lien thereon (but not in any Proceeds thereof) shall cease, and shall be deemed to have ceased immediately prior to such Collateral becoming Transferred Receivables or Related Transferred Rights, without any action by the Collateral Agent or any other Secured Party; provided that the Transaction Lien on any Transferred Receivable or Related Transferred Right shall not be released if (i) a Specified Event of Default shall have occurred and is continuing and (ii) the Required Secured Lenders have delivered a notice to the Collateral Agent instructing that no Transferred Receivable or Related Transferred Right be released from any Transaction Lien during the continuance of such Specified Event of Default. The Collateral Agent shall be fully protected in

relying on a certificate of the relevant Lien Grantor stating that any Collateral qualifies as Transferred Receivables or Related Transferred Rights.

(d) Upon any Collateral of any Lien Grantor consisting of Investment Property subject to a put/call arrangement not expressly prohibited by the terms of any Credit Agreement being transferred to any Person other than another Lien Grantor as a result of the exercise of such put/call arrangement, the Transaction Lien thereon (but not in any Proceeds thereof) will cease immediately without any action by the Collateral Agent or any other Secured Party; provided that no Specified Event of Default shall have occurred and is continuing or would result therefrom.

(e) Upon any Collateral of any Lien Grantor consisting of cash or Investment Property (any such Collateral, “Released Cash Collateral”) being deposited in a Deposit Account or Securities Account which is not subject to the Control of the Collateral Agent as security (a “Third Party Lien”) for the benefit of any Person other than a Lien Grantor in a transaction that does not contravene Section 5.09 of the 2006 Credit Agreement, the Transaction Lien thereon (but not any Proceeds thereof other than, to the extent they might otherwise constitute Proceeds, any amounts constituting payment on or with respect to any Released Cash Collateral, or any investments made with such Released Cash Collateral, in each case (x) made after the release of the Transaction Lien thereon in accordance with this paragraph (e) and (y) only to the extent that such Released Cash Collateral (or investments made with such Released Cash Collateral) remain subject to the Third Party Lien) will cease immediately without any action by the Collateral Agent or any other Secured Party; provided that no Specified Event of Default shall have occurred and is continuing or would result therefrom.

(f) If the continued pledge of any Pledged Equity Interests of any person results in a requirement of the inclusion of separate financial statements of such Person in the filings by any NNC Company under the Exchange Act (except to the extent such financial statements are currently being provided in the Exchange Act filings of any NNC Company on the Effective Date), the Transaction Lien thereon will cease immediately without any action by the Collateral Agent or any other Secured Party; provided that no Specified Event of Default shall have occurred and is continuing or would result therefrom.

(g) In addition to the foregoing, the Collateral Agent may release Collateral with the prior written consent of the Required Secured Lenders.

(h) Upon any termination of a Transaction Lien or release of Collateral, or change in the Secured Obligations of any Lien Grantor, the Collateral Agent will promptly, at the expense of the relevant Lien Grantor, execute and deliver to such Lien Grantor such documents as such Lien Grantor shall reasonably request to evidence the termination of such Transaction Lien or the release of such Collateral, or change in the Secured Obligations, as the case may be, and shall deliver to such Lien Grantor any documents or instruments, including without limitation stock certificates, evidencing any Collateral no longer subject to any Transaction Liens in each case subject only to (i) the delivery of the certificate referred to in paragraph (c) above and (ii) evidence reasonably satisfactory to the Collateral Agent that the Collateral purported to be released under any of paragraphs (b) through (f) above in fact qualifies for such release (which evidence may take the form of a certificate to that effect from NNL and NNI, and the Collateral Agent shall be fully protected in relying on any such certificate).
