	(b)		Such Lien Grantor will maintain its Material Intellectual Property in a commercially reasonable, prudent manner consistent with its past practices and with respect to any Material Intellectual Property which has been infringed, misappropriated or diluted, in each case in a material respect, by a third party, the relevant Lien Grantor will, unless such Lien Grantor shall reasonably determine that such action would be of negligible value, economic or otherwise, take commercially reasonable steps consistent with its past practices to ▇▇▇ for infringement, misappropriation or dilution and to recover any and all damages for such infringement, misappropriation or dilution, and/or take such other actions as such Lien Grantor shall reasonably deem appropriate under the circumstances to protect such Material Intellectual Property.

SECTION 6. SECURITIES AND OTHER INVESTMENTS

Each Lien Grantor represents and warrants, at the times set forth below, and covenants, where indicated below, as follows:

	(a)		Certificated Securities. Such Lien Grantor represents and warrants that, as of the Effective Date, such Lien Grantor has delivered to the Collateral Agent as Collateral hereunder all certificates representing (i) any Pledged certificated Securities of any Subsidiary (the “Pledged Certificated Securities”) and (ii) any other Pledged Certificated Securities owned as of such date by such Lien Grantor and not credited to a Securities Account having a fair market value in excess of $3,000,000 (other than Securities evidencing Equity Interests constituting minority investments in privately held companies). Such Lien Grantor covenants that whenever such Lien Grantor acquires any certificate representing a Pledged Certificated Security described in clauses (i) or (ii) of the immediately preceding sentence, such Lien Grantor will as promptly as practicable deliver such certificate to the Collateral Agent as Collateral hereunder, provided that such Lien Grantor shall not be required to deliver Pledged Certificated Security which such Lien Grantor intends to sell within 90 days of its acquisition thereof until the 91^st day following such acquisition provided that no Event of Default shall have occurred and is continuing.

	(b)		Uncertificated Securities. On or prior to April 30, 2006 (or such later date as to which the Collateral Agent may consent in its sole discretion), in respect of each pledged uncertificated Security owned by such Lien Grantor and not credited to a Securities Account evidencing a Pledged uncertificated Security of such Lien Grantor, such Lien Grantor shall (i) in the case of any Pledged uncertificated Security held at a depository institution or securities intermediary whose jurisdiction is in Canada, give written instructions to the relevant depository institution or other applicable Person, together with a written copy thereof to the Collateral Agent, sufficient for the depository institution or other applicable Person to record in its book entry system that the Collateral Agent is the pledgee of such pledged uncertificated Security (“Pledged Uncertificated Securities”) then owned by such Lien Grantor as of such date and as of such date not being credited to a Securities Account having a fair market value in excess of $5,000,000 as of such date, (ii) in the case of any Pledged Uncertificated Security owned by such Lien Grantor as of such date and held at a Securities Intermediary whose jurisdiction is in the United States of America and having a fair market value in excess of $5,000,000, enter into a Securities Account Control Agreement to the extent required by Section 6(c) and (iii) in the case of any other Pledged Uncertificated Securities owned by such Lien Grantor as of such date and issued by a person whose jurisdiction of formation or incorporation is in the United States of America and having a fair market value in excess of $5,000,000, enter into an Issuer Control Agreement on or prior to April 30, 2006 (or such later date as to which the Collateral Agent may consent in its sole discretion) in respect of each such Pledged Uncertificated Security, and deliver each such Issuer Control Agreement to the Collateral Agent (which shall enter into the same); provided that none of the requirements set forth above shall apply to Securities evidencing

			Equity Interests in Subsidiaries and Equity Interests constituting minority investments in privately held companies. Each Lien Grantor represents and warrants that, as of the Effective Date, no Pledged Equity Interests of any U.S. Subsidiary or any Canadian Subsidiary of any Lien Grantor is an Uncertificated Security. Such Lien Grantor covenants that whenever such Lien Grantor acquires any other Pledged Uncertificated Securities described in clauses (i) or (ii) of the immediately preceding sentence, such Lien Grantor shall give written instructions to the relevant depository institution or other applicable Person, together with a written copy thereof to the Collateral Agent, sufficient for the depository institution or other Person to record in its book entry system that the Collateral Agent is the pledgee of such after-acquired Pledged Uncertificated Securities, 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 or, if the issuer under any such agreement is a Subsidiary, the Issuer.

	(c)		Security Entitlements. Each Lien Grantor covenants to enter into (and cause the relevant Securities Intermediary to enter into) a Securities Account Control Agreement on or prior to April 30, 2006 (or such later date as to which the Collateral Agent may consent in its sole discretion) (the “Required Securities Account Control Agreement Date”) in respect of any Pledged Security Entitlement that is credited to a Securities Account and that is owned by it at such time with a fair market value (together with all other Financial Assets credited to the same Securities Account) in excess of $5,000,000 and will deliver such Securities Account Control Agreement to the Collateral Agent (which shall enter into the same) 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 the covenant with respect to Securities Accounts for which the relevant Securities Intermediary’s jurisdiction is in the United States. Except as permitted by Section 19, such Lien Grantor shall not, on or prior to the Required Securities Account Control Agreement Date, transfer Pledged Security Entitlements out of any Securities Account for the principal purpose of preventing the Collateral Agent from having a perfected lien in such Pledged Security Entitlements (it being understood that nothing herein shall prevent any Lien Grantor from withdrawing cash from any Securities Account for any other purpose). Such ▇▇▇▇ ▇▇▇▇▇ covenants that whenever such Lien Grantor acquires any other Pledged Security Entitlements that are credited to a Securities Account and the underlying Financial Assets of which, together with all other Financial Assets credited to the same Securities Account, have an aggregate fair market value in excess of $5,000,000, such Lien Grantor will, as promptly as practicable, cause the underlying Financial Asset to be credited to a Controlled Securities Account; provided that the Lien Grantors shall not be so obligated if the jurisdiction of the relevant Securities Intermediary is not in the United States.

	(d)		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 Securities owned by it to the Collateral

			Agent in Canada and complies with subsection 6(e) in connection with such delivery, (i) the Transaction Lien on the Pledged Certificated Securities will be perfected by possession, provided that the Collateral Agent takes possession of the Pledged Certificated Securities and that possession thereof as collateral is retained by the Collateral Agent or a person on its behalf other than such Lien Grantor or its agent, and (ii) provided that the Collateral Agent is acting in good faith and has no notice of any adverse claim affecting the Pledged Certificated Securities, the Transaction Lien on the Pledged Certificated Securities has priority over any other security interest in the Pledged Certificated Securities perfected by registration or temporarily perfected under the PPSA.

	(e)		Perfection as to Uncertificated Securities. Such Lien Grantor represents and warrants that (i) the Transaction Lien on the Pledged Uncertificated Securities held at a depository institution of Securities intermediary whose jurisdiction is in Canada has been perfected by all necessary filings in Canada and (ii) provided that the Collateral Agent is acting in good faith and has no notice of any adverse claim affecting the Pledged Uncertificated Securities, the Transaction Lien on the Pledged Uncertificated Securities has priority over any other security interest in the Pledged Uncertificated Securities perfected by registration or temporarily perfected under the PPSA. 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 and of the type described in clause (iii) of Section 6(b) 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.

	(f)		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.

	(g)		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.

	(h)		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.

	(i)		ULC Shares.

	(i)		The parties hereto acknowledge that certain of the Pledged Equity Interests may consist of shares of stock or other Pledged Equity Interests (“ULC Shares”) of one or more unlimited liability companies (each, a “ULC”) under the Companies Act (Nova Scotia) and/or the Business Corporations Act (Alberta) and, to best ensure that neither the Collateral Agent nor any of the Secured Parties could, under any circumstances prior to realization be held to be a “member” or a “shareholder”, as applicable, of the ULC for the purposes of the Companies Act (Nova Scotia) and/or the Business Corporations Act (Alberta), certain provisions of this Agreement are to apply differently insofar as any Pledged Equity Interests consists of ULC Shares.

	(ii)		Notwithstanding any provisions to the contrary contained in this Agreement, or any Credit Agreement, where a Lien Grantor is the sole registered and beneficial owner of ULC Shares which are Pledged Equity Interests, such Lien Grantor will remain the sole registered and beneficial owner of such ULC Shares until such time as such ULC Shares are effectively transferred into the name of the Collateral Agent, any Secured Party or any other Person on the books and records of such ULC. Accordingly, such Lien Grantor shall be entitled to receive and retain for its own account any dividend on or other distribution, if any, in respect of such ULC Shares (except insofar as such Lien Grantor has granted a security interest in such dividend on or other distribution, and any shares which are Pledged Equity Interests shall be delivered to the Collateral Agent to hold as Pledged Equity Interests hereunder) and shall have the right to vote such ULC Shares and to control the direction, management and policies of the ULC to the same extent as the Lien Grantor would if such ULC Shares were not pledged to the Collateral Agent (for its own benefit and for the benefit of the Secured Parties) pursuant hereto. Nothing in this Agreement or any Credit Agreement is intended to, and nothing in this Agreement or any Credit Agreement shall, constitute the Collateral Agent, any of the Secured Parties or any Person other than the Lien Grantor, a member of a ULC for the purposes of the Companies Act (Nova Scotia) or a shareholder of a ULC for the purposes of the Business Corporations Act (Alberta), as applicable (whether listed or unlisted, registered or beneficial), until such time as notice is given to the Lien Grantor and further steps are taken pursuant hereto or thereto so as to

			register the Collateral Agent or such other Person, as specified in such notice, as the holder of the ULC Shares. To the extent any provision hereof would have the effect of constituting the Collateral Agent or any of the Secured Parties as a member or a shareholder, as applicable, of any ULC prior to such time, such provision shall be severed herefrom and shall be ineffective with respect to ULC Shares which are Pledged Equity Interests without otherwise invalidating or rendering unenforceable this Agreement or invalidating or rendering unenforceable such provision insofar as it relates to Pledged Equity Interests which are not ULC Shares.

	(iii)		Except upon the exercise of rights to sell, transfer or otherwise dispose of the Pledged Equity Interests issued by a ULC following the occurrence and during the continuance of an Event of Default or a Specified Event of Default pursuant to Section 12, no Lien Grantor shall cause or permit, or enable any ULC in which it holds ULC Shares which are Pledged Equity Interests to cause or permit, the Collateral Agent or any other Secured Party to: (a) be registered by the ULC as members or shareholders, as applicable, of such ULC; (b) have any notation entered by the ULC in their favour in the share register of such ULC; (c) be held out as members or shareholders, as applicable, of such ULC; or (d) be paid, directly or indirectly, any dividends, property or other distributions from the ULC by reason of the Collateral Agent or the Secured Parties holding a security interest in the ULC Shares; or (e) to act as a member or shareholder, as applicable, of the ULC, or exercise any rights of a member or shareholder, as applicable, including the right to attend a meeting of, or to vote the shares of, the ULC.

SECTION 7. CONTROLLED DEPOSIT ACCOUNTS.

	(i)		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 of which is held at a depository institution whose jurisdiction is in the United States as determined pursuant to UCC Section 9-304. 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.

	(ii)		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 UCC is in effect.

	(iii)		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.

	(iv)		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.

	(v)		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).

SECTION 9. OPERATION OF CASH COLLATERAL ACCOUNTS; CARE AND USE OF COLLATERAL

	(a)		All Cash Distributions received with respect to assets held in any Cash 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 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 Cash Collateral Account to any other account owned by an NNC Company unless such other account is a Cash 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 Cash 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 Cash 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 Cash 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.

To the extent permitted by applicable law, any Receiver appointed by the Collateral Agent will (for purposes relating to responsibility for the Receiver’s acts or omissions) be considered to be the agent of the applicable Lien Grantor and not of the Collateral Agent or the Secured Parties.

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(a) in respect of a Contingent Secured Obligation, the Collateral Agent shall not apply any monies to pay such Contingent Secured Obligation but 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, 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; (iii) 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 (iv) 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 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 wilful misconduct or a breach of any duty that the Collateral Agent has under this Agreement (after giving effect to Section 17 and Section 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, withholding 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 comply with the provisions of the PPSA.

For the purposes of holding any security granted by any Lien Grantors pursuant to the laws of the Province of Quebec, each Secured Party hereby irrevocably appoints and authorizes JPMorgan Chase Bank, N.A. to act as the person holding the power of attorney (in such capacity, the “fondé de pouvoir”) of such Secured Parties and as contemplated under Article 2692 of the Civil Code of Quebec, and to enter into, to take and to hold on their behalf, and for their benefit, each hypothec granted by the Lien Grantors under the Civil Code of Quebec (a “Hypothec”), and to exercise such powers and duties which are conferred upon the fondé de pouvoir under each Hypothec. Moreover, without prejudice to such appointment and authorization to act as the Person holding the power of attorney as aforesaid, each Secured Party hereby irrevocably appoints and authorizes JPMorgan Chase Bank, N.A., as Collateral Agent (in such capacity, the “Custodian”) to act as agent and custodian for and on behalf of such Secured Parties to hold and to be the sole registered holder of any debenture or bond which may be issued under any Hypothec, the whole notwithstanding Section 32 of the Act Respecting the Special Powers of Legal Persons (Quebec) or any other applicable Law. In this respect, (i) records shall be kept indicating the names and addresses of, and the pro rata portion of the obligations and indebtedness secured by any pledge of any such debenture or bond and owing to, each Secured Party, and (ii) each Secured Party will be entitled to the benefits of any Collateral covered by any Hypothec and will participate in the proceeds of realization of any such Collateral, the whole in accordance with the terms hereof. Each of the fondé de pouvoir and the Custodian shall (a)

exercise, in accordance with the terms hereof, all rights and remedies given to the fondé de pouvoir and the Custodian (as applicable) with respect to the Collateral under any Hypothec, any debenture or bond or pledge thereof relating to any Hypothec, applicable laws or otherwise, (b) benefit from and be subject to all provisions hereof with respect to the Collateral Agent mutatis mutandis, including, without limitation, all such provisions with respect to the liability or responsibility to and indemnification by the Secured Parties, and (c) be entitled to delegate from time to time any of its powers or duties under any Hypothec, any debenture or bond or pledge thereof relating to any Hypothec, applicable laws or otherwise and on such terms and conditions as it may determine from time to time. Any Person who becomes a Secured Party shall be deemed to have consented to and confirmed: (i) the fondé de pouvoir as the Person holding the power of attorney as aforesaid, and to have ratified, as of the date it acquired its Secured Obligations, all actions taken by the fondé de pouvoir as the Person holding the power of attorney as aforesaid; and (ii) the Custodian as the agent and custodian as aforesaid and to have ratified, as the date it acquired its Secured Obligations, all actions taken by the Custodian in such capacity. JPMorgan Chase Bank, N.A. accepts the foregoing appointments as fondé de pouvoir and Custodian and agrees to act in such capacities.

The execution by the fondé de pouvoir, as the person holding the power of attorney, prior to the Canadian Security Agreement, of any deed of hypothec or other security document is hereby ratified and confirmed.

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 wilful 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 PPSA 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 bank serving as 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 wilful 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 wilful 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, 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 17(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 (x) 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 Securities 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 other investments 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).

Any Person may become a party hereto by signing and delivering to the Collateral Agent a Security Agreement Supplement, whereupon such Person shall become a “Lien Grantor” as defined herein.

SECTION 21. ADDITIONAL SECURED OBLIGATIONS

Each Lien Grantor may from time to time designate its obligations under any Hedging Agreement (a “Designated Hedging Agreement”) with any Lender or Affiliate of a Lender as an additional Secured Obligation for purposes hereof by delivering to the Collateral Agent a certificate signed by a financial officer that (i) identifies such Hedging Agreement, specifying the name and address of the other party thereto, the notional principal amount thereof and the expiration date thereof and (ii) states that such Lien Grantor’s obligations (as applicable) thereunder are designated as Secured Obligations for purposes hereof; provided that the holder of such Designated Hedging Agreement shall have provided a supplement to this Agreement agreeing to be bound by the terms hereof that are applicable to it including, without limitation, Section 18.

SECTION 23. NO IMPLIED WAIVERS; REMEDIES NOT EXCLUSIVE

No failure by the Collateral Agent or any Secured Party to exercise, and no delay in exercising and no course of dealing with respect to, any right or remedy under any Security Document shall operate as a waiver thereof; nor shall any single or partial exercise by the Collateral Agent or any Secured Party of any right or remedy under any Loan Document preclude any other or further exercise thereof or the exercise of any other right or remedy. The rights and remedies specified in the Loan Documents are cumulative and are not exclusive of any other rights or remedies provided by law.

SECTION 24. SUCCESSORS AND ASSIGNS

This Agreement is for the benefit of the Collateral Agent and the Secured Parties. If all or any part of any Secured Party’s interest in any Secured Obligation is assigned or otherwise transferred in accordance with the transfer provisions applicable thereto, the transferor’s rights hereunder, to the extent applicable to the obligation so transferred, shall be automatically transferred with such obligation. This Agreement shall be binding on the Lien Grantors and their respective successors and assigns.

SECTION 25. AMENDMENTS AND WAIVERS

Except as expressly provided herein, neither this Agreement nor any provision hereof may be waived, amended, modified or terminated except pursuant to an agreement or agreements in writing entered into by the parties hereto, with the consent of the Required Secured Lenders.

SECTION 26. CHOICE OF LAW

This Agreement shall be construed in accordance with and governed by the laws of the Province of Ontario and the federal laws of Canada applicable therein, except as otherwise required by mandatory provisions of law.

SECTION 27. JUDGMENT CURRENCY

If for the purpose of obtaining judgment in any court it is necessary to convert a sum due from a Lien Grantor in the currency expressed to be payable in any Loan Document (the “specified currency”) into another currency, the parties hereto agree, to the fullest extent that they may effectively do so, that the rate of exchange used shall be that at which in accordance

with normal banking procedures the Collateral Agent could purchase the specified currency with such other currency at the Collateral Agent’s Toronto office on the domestic Business Day preceding that on which final judgment is given. The obligations of the Lien Grantor in respect of any sum due to the Collateral Agent hereunder shall, notwithstanding any judgment in a currency other than the specified currency, be discharged only to the extent that on the domestic Business Day following receipt by the Collateral Agent of any sum adjudged to be so due in such other currency the Collateral Agent may in accordance with normal banking procedures purchase the specified currency with such other currency; if the amount of the specified currency so purchased is less than the sum originally due to the Collateral Agent, in the specified currency, the Lien Grantor agrees, to the fullest extent that it may effectively do so, as a separate obligation and notwithstanding any such judgment, to indemnify the Collateral Agent, against such loss, and if the amount of the specified currency so purchased exceeds the sum originally due to the Collateral Agent, in the specified currency, then the Collateral Agent agrees to remit such excess to the Lien Grantor.

SECTION 28. INTEREST ACT

For purposes of disclosure pursuant to the Interest Act (Canada), the annual rates of interest or fees to which the rates of interest or fees provided in any Credit Agreement and in this Agreement (and stated herein as applicable to be computed on the basis of a 365 day year or any other period of time less than a calendar year) are equivalent are the rates so determined multiplied by the actual number of days in the applicable calendar year and divided by 365 or such other period of time.

SECTION 29. WAIVER OF JURY TRIAL

EACH PARTY HERETO IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO ANY SECURITY DOCUMENT OR ANY TRANSACTION CONTEMPLATED THEREBY AND FOR ANY COUNTERCLAIM THEREIN (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR COUNSEL OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

SECTION 30. SEVERABILITY

If any provision of any Security Document is invalid or unenforceable in any jurisdiction, then, to the fullest extent permitted by law, (a) the other provisions of the Security Documents shall remain in full force and effect in such jurisdiction and shall be liberally construed in favour of the Collateral Agent and the Secured Parties in order to carry out the intentions of the parties thereto as nearly as may be possible and (b) the invalidity or unenforceability of such provision in such jurisdiction shall not affect the validity or enforceability thereof in any other jurisdiction.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed by their respective authorized officers as of the day and year first above written.

ISSUER CONTROL AGREEMENT dated as of [the date of execution hereof] among ___(the “Lien Grantor”), JPMORGAN CHASE BANK, N.A., as Collateral Agent (the “Secured Party”), and ___(the “Issuer”). All references herein to the “UCC” refer to the Uniform Commercial Code as in effect from time to time in [Issuer’s jurisdiction of incorporation].

W I T N E S S E T H :

WHEREAS, the Lien Grantor is the registered holder of [specify Pledged Uncertificated Securities issued by the Issuer] issued by the Issuer (the “Securities”);

WHEREAS, pursuant to a Security Agreement dated as of February 14, 2006 (as such agreement may be amended and/or supplemented from time to time, the “Security Agreement”), the Lien Grantor has granted to the Secured Party a continuing security interest (the “Transaction Lien”) in all right, title and interest of the Lien Grantor in, to and under the Securities, whether now existing or hereafter arising; and

WHEREAS, the parties hereto are entering into this Agreement in order to perfect the Transaction Lien on the Securities;

NOW, THEREFORE, the parties hereto agree as follows:

SECTION 1. Nature of Securities. The Issuer confirms that (i) the Securities are “uncertificated securities” (as defined in Section 8 102 of the UCC) and (ii) the Lien Grantor is registered on the books of the Issuer as the registered holder of the Securities.

SECTION 2. Instructions. The Issuer agrees to comply with any “instruction” (as defined in Section 8 102 of the UCC) originated by the Secured Party and relating to the Securities without further consent by the Lien Grantor or any other person. The Lien Grantor consents to the foregoing agreement by the Issuer.

SECTION 3. Waiver of Lien; Waiver of Set-off. The Issuer waives any security interest, lien or right of setoff that it may now have or hereafter acquire in or with respect to the Securities. The Issuer’s obligations in respect of the Securities will not be subject to deduction, set off or any other right in favour of any person other than the Secured Party.

SECTION 4. Choice of Law. This Agreement shall be governed by the laws of [Issuer’s jurisdiction of incorporation].

SECTION 5. Conflict with Other Agreements. There is no agreement (except this Agreement) between the Issuer and the Lien Grantor with respect to the Securities [except for [identify any existing other agreements] (the “Existing Other Agreements”)].

SECTION 6. Amendments. No amendment or modification of this Agreement or waiver of any right hereunder shall be binding on any party hereto unless it is in writing and is signed by all the parties hereto.

SECTION 7. Notice of Adverse Claims. Except for the claims and interests of the Secured Party and the Lien Grantor in the Securities, the Issuer does not know of any claim to, or interest in, the Securities.

SECTION 8. Maintenance of Securities. In addition to, and not in lieu of, the obligation of the Issuer to honour instructions as agreed in Section 2 hereof, the Issuer agrees as follows:

So long as the Issuer has not received a Notice of Exclusive Control (as defined below), the Issuer shall comply with instructions of the Lien Grantor or any duly authorized agent of the Lien Grantor in respect of the Securities. After the Issuer receives a written notice from the Secured Party that it is exercising exclusive control over the Securities (a “Notice of Exclusive Control”), the Issuer will cease complying with instructions of the Lien Grantor or any of its agents.

(ii) Non Cash Dividends and Distributions. After the Issuer receives a Notice of Exclusive Control, the Issuer shall deliver to the Secured Party all dividends, interest and other distributions paid or made upon or with respect to the Securities.

(iii) Voting Rights. Until the Issuer receives a Notice of Exclusive Control, the Lien Grantor shall be entitled to direct the Issuer with respect to voting the Securities.

(iv) Statements and Confirmations. The Issuer will promptly send copies of all statements and other correspondence concerning the Securities simultaneously to each of the Lien Grantor and the Secured Party at their respective addresses specified in Section 11 hereof.

(v) Tax Reporting. All items of income, gain, expense and loss recognized in respect of the Securities shall be reported to the Internal Revenue Service and all state and local taxing authorities under the name and taxpayer identification number of the Lien Grantor.
