SPECIAL PROVISIONS CONCERNING ACCOUNTS; CONTRACT RIGHTS; SECURITIES; INSTRUMENTS; CHATTEL PAPER AND CERTAIN OTHER COLLATERAL

Section 3.1 Additional Representations and Warranties.

As of the time when each of its Accounts arises, each Assignor shall be deemed to have represented and warranted that each such Eligible Account, and all records, papers and documents relating thereto (if any) are genuine and what they purport to be, and that all papers and documents (if any) relating thereto (i) will, to the knowledge of a Responsible Officer of such Assignor, represent the genuine, legal, valid and binding obligation of the account debtor evidencing indebtedness unpaid and owed by the respective account debtor arising out of the performance of labor or services or the sale or lease and delivery of the merchandise listed therein, enforceable against the account debtor in accordance with its terms, subject to applicable bankruptcy, insolvency or other similar laws generally affecting creditors’ rights and equitable principles, or both, (ii) will be the only original writings evidencing and embodying such obligation of the account debtor named therein (other than copies created for general accounting purposes or other ordinary corporate purposes), and (iii) will be in compliance and will conform in all material respects with all applicable federal, provincial and local laws and applicable laws of any relevant foreign jurisdiction.

Section 3.2 Maintenance of Records.

Each Assignor will keep and maintain at its own cost and expense accurate records of its Accounts and Contracts, in accordance with Section 9.02 of the Credit Agreement, and such Assignor will make the same available on such Assignor’s premises to the Collateral Agent for inspection in accordance with Section 9.02 the Credit Agreement. Upon the occurrence and during the continuance of an Event of Default and at the request of the Collateral Agent, such Assignor shall, at its own cost and expense, deliver copies (or, if requested by the Collateral Agent after the occurrence and during the continuance of an Event of Default, originals) of all tangible evidence of its Accounts and Contract Rights (including, all documents evidencing the Accounts and all Contracts) and such books and records to the Collateral Agent or to its representatives (copies of such evidence and books and records may be retained by such Assignor). Upon the occurrence and during the continuance of an Event of Default and if the Collateral Agent so directs, such Assignor shall legend, in form and manner reasonably satisfactory to the Collateral Agent, the Accounts and the Contracts, as well as books, records and documents (if any) of such Assignor evidencing or pertaining to such Accounts and Contracts with an appropriate reference to the fact that such Accounts and Contracts have been assigned to the Collateral Agent and that the Collateral Agent has a security interest therein.

Section 3.3 Direction to Account Debtors; Contracting Parties; etc.

Upon the occurrence and during the continuance of an Event of Default (but without limiting the provisions of the Credit Agreement), if the Collateral Agent so directs any Assignor, such Assignor agrees (A) to cause all payments on account of the Accounts and Contracts to be made directly to the Cash Collateral Account, (B) that the Collateral Agent may, at its option, directly notify the obligors with respect to any Accounts and/or under any Contracts to make payments with respect thereto as provided in the preceding clause (A), and (C) that the Collateral Agent may enforce collection of any such Accounts and Contracts and may adjust, settle or compromise the amount of payment thereof, in the same manner and to the same extent as such Assignor. Without notice to or assent by any Assignor, the Collateral Agent may, upon the occurrence and during the continuance of an Event of Default, apply any or all amounts then in, or thereafter deposited in, the Cash Collateral Account toward the payment

- 14 -

of the Obligations in the manner provided in Section 5.6 of this Agreement. The reasonable out-of-pocket costs and expenses of collection (including reasonable out-of-pocket attorneys’ fees), whether incurred by an Assignor or the Collateral Agent, shall be borne by the relevant Assignor. The Collateral Agent shall deliver a copy of each notice given to any such obligors referred to in the preceding clause (B) to the relevant Assignor, provided that (x) the failure by the Collateral Agent to so notify such Assignor shall not affect the effectiveness of such notice or the other rights of the Collateral Agent created by this Section 3.3 and (y) no such notice shall be required if an Event of Default of the type described in Section 11.05 of the Credit Agreement has occurred and is continuing.

Section 3.4 Modification of Terms; etc.

Except (w) in accordance with such Assignor’s ordinary course of business, (x) as otherwise in such Assignor’s reasonable business judgment, (y) as permitted by the Credit Agreement or (z) as permitted by Section 3.5 hereof, no Assignor shall rescind or cancel any indebtedness evidenced by any Account or under any Contract, or modify any term thereof or make any adjustment with respect thereto, or extend or renew the same, or compromise or settle any dispute, claim, suit or legal proceeding relating thereto, or sell any Account or Contract, or interest therein, without the prior written consent of the Collateral Agent. Except to the extent otherwise permitted by this Agreement or the Credit Agreement, no Assignor will do anything to impair the rights of the Collateral Agent in the Accounts or Contracts.

Section 3.5 Collection.

Except as such Assignor otherwise determines in its reasonable business judgment, each Assignor shall endeavor in accordance with reasonable business practices to cause to be collected from the account debtor named in each of its Accounts or obligor under any Contract, as and when due (including, amounts which are delinquent, such amounts to be collected in accordance with generally accepted lawful collection procedures) any and all amounts owing under or on account of such Account or Contract, and apply promptly upon receipt thereof all such amounts as are so collected to the outstanding balance of such Account or under such Contract. Except as otherwise directed by the Collateral Agent after the occurrence and during the continuation of an Event of Default, any Assignor may allow in the ordinary course of business as adjustments to amounts owing under its Accounts and Contracts (i) an extension or renewal of the time or times of payment, or settlement for less than the total unpaid balance, which such Assignor finds appropriate in accordance with its reasonable business judgment, (ii) a refund or credit due as a result of returned or damaged merchandise or improperly performed services or for other reasons which such Assignor finds appropriate in accordance with its reasonable business judgment and (iii) such other adjustments which such Assignor finds appropriate in accordance with its reasonable business judgment.

Section 3.6 Securities and Instruments.

(a) Annex G and Annex H list all Securities and Instruments owned or held by such Assignor on the date of this Agreement. Annex G sets out, for each class of Securities listed in the schedule, the percentage amount that such Securities represent of all issued and outstanding Securities of that class and whether the Securities are certificated securities or uncertificated securities.

(b) Securities and Instruments that are Collateral have been, where applicable, duly and validly issued and acquired and are fully paid and non-assessable (subject to the assessibility of any ULC Shares) and are subject to no options to purchase or similar rights.

- 15 -

(c) Except as described in Annex G or Annex H, no transfer restrictions apply to the Securities and Instruments listed in Annex G or Annex H. Each Assignor has delivered to the Collateral Agent copies of all shareholder, partnership or trust agreements applicable to each issuer of such Securities and Instruments which are in such Assignor’s possession and confirms that any interest in a partnership or limited liability company that now, or at any time, forms part of the Collateral is, and will be, a “security” for the purposes of the STA.

(d) The Securities and Instruments that are Collateral constitute, where applicable, the legal, valid and binding obligation of such Assignor of such Securities and Instruments, enforceable in accordance with their terms, subject only to any limitation under applicable laws relating to (i) bankruptcy, insolvency, fraudulent conveyance, arrangement, reorganization or creditors’ rights generally, and (ii) the discretion that a court may exercise in the granting of equitable remedies.

(e) The security interests created under this Agreement (when executed and delivered by all parties hereto) are effective to create in favour of the Collateral Agent, for the benefit of the Secured Creditors, a legal, valid and enforceable security interest in all right, title and interest of the Assignors in all of the Collateral, and when proper PPSA financing change statements have been filed in the appropriate filing offices against each Assignor, the Collateral Agent, for the benefit of the Secured Creditors, shall have a perfected security interest in all Collateral to the extent such security interest can be perfected by filing a PPSA financing change statement under the PPSA subject to no security interests of any other Person (other than Permitted Liens (it being understood that the Permitted Liens described in Section 10.02(s) of the Credit Agreement are subject to the terms of the Intercreditor Agreement at any time that Permitted Additional Secured Indebtedness is outstanding), subject to the terms of the Intercreditor Agreement at any times that Permitted Additional Secured Indebtedness is outstanding, Permitted Liens described in Section 10.01(s) of the Credit Agreement).

(f) Such Assignor has not consented to, will not consent to, and has no knowledge of any control by any person with respect to any Collateral other than the Collateral Agent.

(g) Such Assignor will notify the Collateral Agent immediately upon becoming aware of any change in an “issuer’s jurisdiction” in respect of any uncertificated Securities that are Collateral or any change in a “securities intermediary’s jurisdiction” in respect of any security entitlements, financial assets or Securities Accounts that are Collateral.

For the purpose of this Section 3.6, (i) references to the term “Instrument” shall be limited to subsection (i) and (v) of the definition of “Instrument” and shall only refer to Instruments with a value equal to US$3,000,000 or more constituting Collateral and (ii) references to the term “Securities” shall be limited to Securities in the Subsidiaries of such Assignor.

Section 3.7 Voting.

Unless and until there shall have occurred and be continuing any Event of Default, each Assignor shall be entitled to exercise any and all voting and other rights pertaining to the Collateral owned by it, and to give consents, waivers or ratifications in respect thereof; provided that, in each case, no vote shall be cast or any consent, waiver or ratification given or any action taken or omitted to be taken which would violate, or result in a breach of any covenant contained in, any of the terms of any Secured Debt

- 16 -

Agreement, or in a manner adverse to the interests of the Collateral Agent or any other Secured Creditor in the Collateral in any material respect, unless permitted by the terms of any Secured Debt Agreements. For greater certainty, nothing in this paragraph is intended to suggest that an Assignor pledging ULC Shares would not have the rights provided for in this subsection in the absence of this subsection. Except in the case of ULC Shares, all such rights of each Assignor to vote and to give consents, waivers and ratifications shall cease following written notice from the Collateral Agent in case an Event of Default has occurred and is continuing (provided that no such notice shall be required if any Event of Default under Section 11.05 of the Credit Agreement has occurred and is continuing), and Section 5.1 hereof shall become applicable.

Section 3.8 Dividends and Other Distributions.

Except with respect to any ULC Shares, unless and until there shall have occurred and be continuing an Event of Default and following written notice from the Collateral Agent (provided that no such notice shall be required if any Event of Default under Section 11.05 of the Credit Agreement has occurred and is continuing), all cash dividends, cash distributions, cash Proceeds and other cash amounts payable in respect of the Collateral shall be paid to the respective Assignor. For greater certainty, nothing in this paragraph is intended to suggest that an Assignor pledging ULC Shares would not have the rights provided for in this section in the absence of this section. The Assignor shall be entitled to receive (except in the case of proceeds of ULC Shares) directly, subject to the other terms of this Agreement:

(i) all other or additional stock, notes, certificates, limited liability company, partnership interests, instruments or other securities or property (including, but not limited to, cash dividends other than as set forth above) paid or distributed by way of dividend or otherwise in respect of the Collateral;

(ii) all other or additional stock, notes, certificates, limited liability company interests, partnership interest, instruments or other securities or property (including, but not limited to, cash subject to the first sentence of this Section 3.8) paid or distributed in respect of the Collateral by way of stock-split, spin-off, split-up, reclassification, combination of shares or similar rearrangement; and

(iii) all other or additional stock, notes, certificates, limited liability company interests, partnership interest, instruments or other securities or property (including, but not limited to, cash) which may be paid in respect of the Collateral by reason of any consolidation, amalgamation, merger, exchange of stock, conveyance of assets, liquidation or similar corporate or other reorganization.

If an Assignor which has pledged ULC Shares receives any of the property described in the preceding paragraphs (i), (ii) and (iii) such Assignor shall deliver such property to the Collateral Agent to hold as Collateral hereunder.

All cash dividends, cash distributions or other cash payments which are received by any Assignor contrary to the provisions of this Section 3.8 or Section 5.1, with the exception of any dividends, distributions and other payments that are received pertaining to ULC Shares, shall be received in trust for the benefit of the Collateral Agent, shall be segregated from other property or funds of such Assignor and shall be promptly paid over to the Collateral Agent as Collateral in the same form as so received (with any necessary endorsement).

- 17 -

Section 3.9 Assignors Remain Liable Under Accounts.

Anything herein to the contrary notwithstanding, the Assignors shall remain liable under each of the Accounts to observe and perform all of the conditions and obligations to be observed and performed by them thereunder, all in accordance with the terms of any agreement giving rise to such Accounts. Neither the Collateral Agent nor any other Secured Creditor shall have any obligation or liability under any Account (or any agreement giving rise thereto) by reason of or arising out of this Agreement or the receipt by the Collateral Agent or any other Secured Creditor of any payment relating to such Account pursuant hereto, nor shall the Collateral Agent or any other Secured Creditor be obligated in any manner to perform any of the obligations of any Assignor under or pursuant to any Account (or any agreement giving rise thereto), to make any payment, to make any inquiry as to the nature or the sufficiency of any payment received by them or as to the sufficiency of any performance by any party under any Account (or any agreement giving rise thereto), to present or file any claim, to take any action to enforce any performance or to collect the payment of any amounts which may have been assigned to them or to which they may be entitled at any time or times.

Section 3.10 Assignors Remain Liable Under Contracts.

Anything herein to the contrary notwithstanding, the Assignors shall remain liable under each of the Contracts to observe and perform all of the conditions and obligations to be observed and performed by them thereunder, all in accordance with and pursuant to the terms and provisions of each Contract. Neither the Collateral Agent nor any other Secured Creditor shall have any obligation or liability under any Contract by reason of or arising out of this Agreement or the receipt by the Collateral Agent or any other Secured Creditor of any payment relating to such Contract pursuant hereto, nor shall the Collateral Agent or any other Secured Creditor be obligated in any manner to perform any of the obligations of any Assignor under or pursuant to any Contract, to make any payment, to make any inquiry as to the nature or the sufficiency of any performance by any party under any Contract, to present or file any claim, to take any action to enforce any performance or to collect the payment of any amounts which may have been assigned to them or to which they may be entitled at any time or times.

Section 3.11 Letter-of-Credit Rights.

If any Assignor is at any time a beneficiary under a letter of credit constituting Collateral in respect of Eligible Accounts or Eligible Inventory, with a stated amount of $10,000,000 (or such lesser amount as may be required pursuant to the terms of the 2014 Term Facility or any other Permitted Additional Secured Indebtedness) or more in the aggregate, such Assignor shall no later than the next date required to deliver a compliance certificate pursuant to Section 9.01(d) of the Credit Agreement (or such earlier date that any such action is required to be taken pursuant to the terms of the 2014 Term Facility or any other Permitted Additional Secured Indebtedness, and, in any event, as such date may be extended from time to time by the Administrative Agent in its sole discretion), notify the Collateral Agent thereof and, at the request of the Collateral Agent, such Assignor shall, pursuant to an agreement in form and substance reasonably satisfactory to the Collateral Agent, use its commercially reasonable efforts to (i) arrange for the issuer and any confirmer of such letter of credit to consent to an assignment to the Collateral Agent of the proceeds of any drawing under such letter of credit or (ii) arrange for the Collateral Agent to become the transferee beneficiary of such letter of credit, with the Collateral Agent agreeing, in each case, that the proceeds of any drawing under the letter of credit are retained by the Collateral Agent and to be applied as provided in this Agreement only after the occurrence and during the continuance of an Event of Default.

- 18 -

Section 3.12 Further Actions.

Each Assignor will, at its own expense, take such actions as are required by Section 9.12(a) of the Credit Agreement.

ARTICLE 4
PROVISIONS CONCERNING ALL COLLATERAL

Section 4.1 Protection of Collateral Agent’s Security.

Except as otherwise not prohibited by the Credit Documents, no Assignor will do anything to impair the rights of the Collateral Agent in the Collateral. Each Assignor will at all times maintain insurance, at such Assignor’s own expense to the extent and in the manner provided in the Credit Agreement. Except to the extent otherwise permitted to be retained by such Assignor or applied by such Assignor pursuant to the terms of the Credit Agreement, the Collateral Agent shall, at the time any proceeds of such insurance are distributed to the Secured Creditors, apply such proceeds in accordance with Section 5.6 hereof. Each Assignor assumes all liability and responsibility in connection with the Collateral acquired by it and the liability of such Assignor to pay the Obligations shall in no way be affected or diminished by reason of the fact that such Collateral may be lost, destroyed, stolen, damaged or for any reason whatsoever unavailable to such Assignor.

Section 4.2 Additional Information.

Each Assignor will, at its own expense, from time to time upon the reasonable request of the Collateral Agent, promptly (and in any event within 10 days after its receipt of the respective request) furnish to the Collateral Agent such information with respect to the Collateral (including the identity of the Collateral or such components thereof as may have been requested by the Collateral Agent, the value and location of such Collateral, etc.) as may be requested by the Collateral Agent. Without limiting the forgoing, each Assignor agrees that it shall promptly (and in any event within 10 days after its receipt of the respective request) furnish to the Collateral Agent such updated Annexes hereto as may from time to time be reasonably requested by the Collateral Agent.

Section 4.3 Financing Statements.

Each Assignor agrees to authorize, execute (where required by applicable law) and deliver (or cause to be executed and delivered) to the Collateral Agent such financing statements and financing change statements in form reasonably acceptable to the Collateral Agent, as the Collateral Agent may from time to time reasonably request or as are reasonably necessary or desirable in the opinion of, and at the request of, the Collateral Agent in order to establish and maintain a valid, enforceable, perfected security interest in the Collateral as provided herein and the other rights and security contemplated hereby. Each Assignor will pay any applicable filing fees, recordation taxes and related expenses relating to its Collateral. Each Assignor hereby authorizes the Collateral Agent to file any such financing statements or financing change statements without the signature of such Assignor where permitted by law (and such authorization includes describing the Collateral as “all assets” or “all personal property” of such Assignor or words of similar effect). Notwithstanding the foregoing, if reasonably requested by any Assignor, the Collateral Agent shall, at Assignor’s expense, make such filings as may be reasonably requested to evidence that the security interests hereunder do not attach to any property that constitutes Excluded Assets.

- 19 -

ARTICLE 5
REMEDIES UPON OCCURRENCE OF AN EVENT OF DEFAULT

Section 5.1 Remedies; Obtaining the Collateral Upon Default.

Subject to Section 5.3, each Assignor agrees that, if any Event of Default shall have occurred and be continuing, then and in every such case, the Collateral Agent, in addition to any rights now or hereafter existing under applicable law and under the other provisions of this Agreement, shall have all rights as a secured creditor under any PPSA, and such additional rights and remedies to which a secured creditor is entitled under the laws in effect in all relevant jurisdictions and may:

(i) personally, or by agents or attorneys, immediately take possession of the Collateral or any part thereof, from such Assignor or any other Person who then has possession of any part thereof with or without notice or process of law, and for that purpose may enter upon such Assignor’s premises where any of the Collateral is located and remove the same and use in connection with such removal any and all services, supplies, aids and other facilities of such Assignor;

(ii) instruct the obligor or obligors on any agreement, instrument or other obligation (including, the Accounts and the Contracts) constituting the Collateral to make any payment required by the terms of such agreement, instrument or other obligation directly to the Collateral Agent and may exercise any and all remedies of such Assignor in respect of such Collateral;

(iii) instruct all banks which have entered into a control agreement with the Collateral Agent to transfer all moneys, securities and instruments held by such depositary bank to the Cash Collateral Account;

(iv) sell, assign or otherwise liquidate any or all of the Collateral or any part thereof in accordance with Section 5.2 hereof, or direct such Assignor to sell, assign or otherwise liquidate any or all of the Collateral or any part thereof, and, in each case, take possession of the proceeds of any such sale or liquidation;

(v) take possession of the Collateral or any part thereof, by directing such Assignor in writing to deliver the same to the Collateral Agent at any reasonable place or places designated by the Collateral Agent, in which event such Assignor shall at its own expense:

(x) forthwith cause the same to be moved to the place or places so designated by the Collateral Agent and there delivered to the Collateral Agent;

(y) store and keep any Collateral so delivered to the Collateral Agent at such place or places pending further action by the Collateral Agent as provided in Section 5.2 hereof; and

(z) while the Collateral shall be so stored and kept, provide such security and maintenance services as shall be reasonably necessary to protect the same and to preserve and maintain it in good condition;

- 20 -

(vi) except with respect to ULC Shares prior to notice and transfer, exercising and enforcing all rights and remedies of a holder of the Collateral as if the Collateral Agent were the absolute owner thereof (including, if necessary, causing the Collateral to be registered in the name of the Collateral Agent or its nominee if not already done);

vii) collection of any proceeds arising in respect of the Collateral;

(viii) collection, realization or sale of, or other dealing with, accounts;

(ix) instruction or order to any issuer or securities intermediary pursuant to any control agreement that the Collateral Agent has with respect to the Collateral;

(x) exercise the rights granted under Section 1.2 hereof;

(xi) apply any moneys constituting Collateral or proceeds thereof in accordance with the provisions of Section 5.6 hereof;

(xii) appoint by instrument in writing a receiver (which term as used in this Agreement includes a receiver and manager) or agent of all or any part of the Collateral and remove or replace from time to time any receiver or agent;

(xiii) institute proceedings in any court of competent jurisdiction for the appointment of a receiver of all or any part of the Collateral;

(xiv) institute proceedings in any court of competent jurisdiction for sale or foreclosure of all or any part of the Collateral;

(xv) file proofs of claim and other documents to establish claims to the Collateral in any proceeding relating to any Assignor; and

(xvi) exercise any other remedy, or institute any other proceeding, in each case, authorized or permitted under the PPSA or otherwise by law or equity;

it being understood that each Assignor’s obligation so to deliver the Collateral is of the essence of this Agreement and that, accordingly, upon application to a court of equity having jurisdiction, the Collateral Agent shall be entitled to a decree requiring specific performance by such Assignor of said obligation. By accepting the benefits of this Agreement and each other Security Document, the Secured Creditors expressly acknowledge and agree that this Agreement and each other Security Document may be enforced only by the action of the Collateral Agent acting upon the instructions of the Required Lenders and that no other Secured Creditor shall have any right individually to seek to enforce or to enforce this Agreement or to realize upon the security to be granted hereby, it being understood and agreed that such rights and remedies may be exercised by the Collateral Agent for the benefit of the Secured Creditors upon the terms of this Agreement and the other Security Documents.

Section 5.2 Remedies; Disposition of the Collateral.

If any Event of Default shall have occurred and be continuing, then any Collateral repossessed by the Collateral Agent under or pursuant to Section 5.1 hereof and any other Collateral whether or not so repossessed by the Collateral Agent, may be sold, assigned, leased or otherwise disposed of under one or more contracts or as an entirety, and without the necessity of gathering at the place of sale the

- 21 -

property to be sold, and in general in such manner, at such time or times, at such place or places and on such terms as the Collateral Agent may, in compliance with any mandatory requirements of applicable law, determine to be commercially reasonable. Any of such Collateral may be sold, leased or otherwise disposed of, in the condition in which the same existed when taken by the Collateral Agent or after any overhaul or repair at the expense of the relevant Assignor which the Collateral Agent shall determine to be commercially reasonable. Any such sale, lease or other disposition may be effected by means of a public disposition or private disposition, effected in accordance with the applicable law as may apply to the respective disposition. The Collateral Agent may, without notice or publication, adjourn any public or private disposition or cause the same to be adjourned from time to time by announcement at the time and place fixed for the disposition, and such disposition may be made at any time or place to which the disposition may be so adjourned. To the extent permitted by any such requirement of law, the Collateral Agent may bid for and become the purchaser (and may pay all or any portion of the purchase price by crediting Obligations against the purchase price) of the Collateral or any item thereof, offered for disposition in accordance with this Section 5.2 without accountability to the relevant Assignor. If, under applicable law, the Collateral Agent shall be permitted to make disposition of the Collateral within a period of time which does not permit the giving of notice to the relevant Assignor as hereinabove specified, the Collateral Agent need give such Assignor only such notice of disposition as shall be required by such applicable law. Each Assignor agrees to do or cause to be done all such other acts and things as may be reasonably necessary to make such disposition or dispositions of all or any portion of the Collateral valid and binding and in compliance with any and all applicable laws, regulations, orders, writs, injunctions, decrees or awards of any and all courts, arbitrators or governmental instrumentalities, domestic or foreign, having jurisdiction over any such sale or sales, all at such Assignor’s expense.

Section 5.3 ULC Shares.

(a) Notwithstanding anything else contained in this Agreement or any other document or agreement among all or some of the parties hereto, each Assignor is the sole registered and beneficial owner of all its Collateral that is ULC Shares and will remain so until such time as such ULC Shares are effectively transferred into the name of the Collateral Agent, any of the Secured Creditors, or any nominee of the foregoing or any other Person on the books and records of such ULC. Accordingly, such Assignor shall be entitled to receive and retain for its own account any dividend on or other distribution, if any, in respect of ULC Shares that are Collateral and shall have the right to vote such ULC Shares and to control the direction, management and policies of any ULC to the same extent as such Assignor would if such ULC Shares were not pledged to the Collateral Agent for the benefit of the Secured Creditors pursuant hereto. Nothing in this Agreement or any other document or agreement among all or some of the parties hereto is intended to, and nothing in this Agreement or any other document or agreement among all or some of the parties hereto shall, constitute the Collateral Agent, any of the Secured Creditors or any Person other than an Assignor, a member of any ULC for the purposes of Companies Act (Nova Scotia), the Business Corporations Act (British Columbia), the Business Corporations Act (Alberta) or any other applicable legislation until such time as notice is given to such Assignor and further steps are taken hereunder or thereunder so as to register the Collateral Agent, any of the Secured Creditors or any nominee of the foregoing, as specified in such notice, as the holder of shares of such ULC. To the extent any provision hereof would have the effect of constituting the Collateral Agent or any of the Secured Creditors a member of a ULC prior to such time, such provision shall be severed herefrom and ineffective with respect to Collateral that is shares of such ULC without otherwise invalidating or rendering unenforceable this

- 22 -

Agreement or invalidating or rendering unenforceable such provision insofar as it relates to Collateral that is not shares of such ULC.

(b) Except upon the exercise of rights to sell or otherwise dispose of Collateral that is ULC Shares once an Event of Default shall have occurred and be continuing, no Assignor shall cause or permit, or enable any ULC in which it holds ULC Shares that are Collateral to cause or permit, the Collateral Agent or any other Secured Creditor to: (a) be registered as a shareholder or member of a ULC; (b) have any notation entered in its favour in the share register of a ULC; (c) be held out as a shareholder or member of a ULC; (d) receive, directly or indirectly, any dividends, property or other distributions from a ULC by reason of the Collateral Agent or any other Secured Creditor holding a security interest in a ULC or ULC Shares; or (e) act as a shareholder or member of a ULC, or exercise any rights of a shareholder or member including the right to attend a meeting of, or to vote the shares of, a ULC.

Section 5.4 Receiver's Powers.

(a) Any receiver appointed by the Collateral Agent is vested with the rights and remedies which could have been exercised by the Collateral Agent in respect of any Assignor or the Collateral and such other powers and discretions as are granted in the instrument of appointment and any supplemental instruments. The identity of the receiver, its replacement and its remuneration are within the sole and unfettered discretion of the Collateral Agent.

(b) Any receiver appointed by the Collateral Agent will act as agent for the Collateral Agent for the purposes of taking possession of the Collateral, but otherwise and for all other purposes (except as provided below), as agent for the Assignors. The receiver may sell, lease, or otherwise dispose of Collateral as agent for the Assignors or as agent for the Collateral Agent as the Collateral Agent may determine in its discretion. Each Assignor agrees to ratify and confirm all actions of the receiver acting as agent for such Assignor, and to release and indemnify the receiver in respect of all such actions.

(c) The Collateral Agent, in appointing or refraining from appointing any receiver, does not incur liability to the receiver, the Assignors or otherwise and is not responsible for any misconduct or negligence of such receiver.

Section 5.5 Waiver of Claims.

Except as otherwise provided in this Agreement, EACH ASSIGNOR HEREBY WAIVES, TO THE EXTENT PERMITTED BY APPLICABLE LAW, NOTICE AND JUDICIAL HEARING IN CONNECTION WITH THE COLLATERAL AGENT’S TAKING POSSESSION OR THE COLLATERAL AGENT’S DISPOSITION OF ANY OF THE COLLATERAL, IN EACH CASE AFTER THE OCCURRENCE AND DURING THE CONTINUANCE OF AN EVENT OF DEFAULT, INCLUDING, ANY AND ALL PRIOR NOTICE AND HEARING FOR ANY PREJUDGMENT REMEDY OR REMEDIES, and each Assignor hereby further waives, to the extent permitted by law:

(i) all damages occasioned by such taking of possession or any such disposition except any damages which are the direct result of the Collateral Agent’s gross negligence or willful misconduct (as determined by a court of competent jurisdiction in a final and non-appealable decision);

- 23 -

(ii) all other requirements as to the time, place and terms of sale or other requirements with respect to the enforcement of the Collateral Agent’s rights hereunder; and

(iii) all rights of redemption, appraisement, valuation, stay, extension or moratorium now or hereafter in force under any applicable law in order to prevent or delay the enforcement of this Agreement or the absolute sale of the Collateral or any portion thereof, and each Assignor, for itself and all who may claim under it, insofar as it or they now or hereafter lawfully may, hereby waives the benefit of all such laws.

Any sale of, or the grant of options to purchase, or any other realization upon, any Collateral shall operate to divest all right, title, interest, claim and demand, either at law or in equity, of the relevant Assignor therein and thereto, and shall be a perpetual bar both at law and in equity against such Assignor and against any and all Persons claiming or attempting to claim the Collateral so sold, optioned or realized upon, or any part thereof, from, through and under such Assignor.

Section 5.6 Application of Proceeds.

(a) All moneys collected by the Collateral Agent (or, to the extent the Pledge Agreement or any other Security Document requires proceeds of collateral under such other Security Document to be applied in accordance with the provisions of this Agreement, the Pledgee, under, and as defined in the Pledge Agreement or collateral agent under such other Security Document) upon any sale or other disposition of the Collateral (or the collateral under the relevant Security Document), in connection with the Collateral Agent’s exercise of remedies following the occurrence and during the continuance of an Event of Default, together with all other moneys received by the Collateral Agent hereunder or under any other Security Document, shall be applied as follows:

(i) first, to the payment of all amounts owing the Collateral Agent of the type described in clauses (iv), (v), (vi) and (vii) of the definition of “Obligations”;

(ii) second, to the extent proceeds remain after the application pursuant to preceding clause (i), an amount equal to the outstanding Primary Obligations which are Credit Document Obligations shall be paid to the Lender Creditors as provided in Section 5.6(e) hereof, with each such Lender Creditor receiving an amount equal to its outstanding Primary Obligations which are Credit Document Obligations or, if the proceeds are insufficient to pay in full all such Primary Obligations, its Pro Rata Share of the amount remaining to be distributed;

(iii) third, to the extent proceeds remain after the application pursuant to preceding clauses (i) and (ii), an amount equal to the outstanding Secondary Obligations which are Credit Document Obligations shall be paid to the Lender Creditors as provided in Section 5.6(e) hereof, with each such Lender Creditor receiving an amount equal to its outstanding Secondary Obligations which are Credit Document Obligations or, if the proceeds are insufficient to pay in full all such Secondary Obligations, its Pro Rata Share of the amount remaining to be distributed;

- 24 -

(iv) fourth, to the extent proceeds remain after the application pursuant to preceding clauses (i) through (iii), an amount equal to the outstanding Primary Obligations which are Other Obligations shall be paid to the Other Creditors as provided in Section 5.6(e) hereof, with each such Other Creditor receiving an amount equal to its outstanding Primary Obligations which are Other Obligations or, if the proceeds are insufficient to pay in full all such Primary Obligations, its Pro Rata Share of the amount remaining to be distributed;

(v) fifth, to the extent proceeds remain after the application pursuant to preceding clauses (i) through (iv), inclusive, an amount equal to the outstanding Secondary Obligations which are Other Obligations shall be paid to the Other Creditors as provided in Section 5.6(e) hereof, with each such Other Creditor receiving an amount equal to its outstanding Secondary Obligations which are Other Obligations or, if the proceeds are insufficient to pay in full all such Primary Obligations, its Pro Rata Share of the amount remaining to be distributed; and

(vi) sixth, to the extent proceeds remain after the application pursuant to preceding clauses (i) through (v), inclusive, and following the termination of this Agreement pursuant to Section 8.8(a) hereof, to the relevant Assignor or to whomever may be lawfully entitled to receive such surplus.

(b) For purposes of this Agreement: (i) “Pro Rata Share” shall mean, when calculating a Secured Creditor’s portion of any distribution or amount, that amount (expressed as a percentage) equal to a fraction the numerator of which is the then unpaid amount of such Secured Creditor’s Primary Obligations or Secondary Obligations, as the case may be, and the denominator of which is the then outstanding amount of all Primary Obligations or Secondary Obligations owing to the applicable Secured Creditors entitled thereto, as the case may be; (ii) “Primary Obligations” shall mean (x) in the case of the Credit Document Obligations all principal of, premium, fees and interest on, all Loans, all Unpaid Drawings (and all interest thereon), the Stated Amount of (and the obligation to cash collateralize) all outstanding Letters of Credit and all Fees and (y) in the case of the Other Obligations, all amounts due to an Other Creditor under each Secured Hedging Agreement and/or Treasury Services Agreement, as applicable (other than indemnities, fees (including, reasonable attorneys’ fees) and similar obligations and liabilities); and (iii) “Secondary Obligations” shall mean all Obligations other than Primary Obligations.

(c) When payments to Secured Creditors are based upon their respective Pro Rata Shares, the amounts received by such Secured Creditors hereunder shall be applied (for purposes of making determinations under this Section 5.6 only) (i) first, to their Primary Obligations and (ii) second, to their Secondary Obligations. If any payment to any Secured Creditor of its Pro Rata Share of any distribution would result in overpayment to such Secured Creditor, such excess amount shall instead be distributed in respect of the unpaid Primary Obligations or Secondary Obligations, as the case may be, of the other Secured Creditors entitled to such distribution, with each such Secured Creditor whose Primary Obligations or Secondary Obligations, as the case may be, have not been paid in full to receive an amount equal to such excess amount multiplied by a fraction the numerator of which is the unpaid Primary Obligations or Secondary Obligations, as the case may be, of such Secured Creditor and the denominator of which is the unpaid

- 25 -

Primary Obligations or Secondary Obligations, as the case may be, of all Secured Creditors entitled to such distribution.

(d) Each of the Secured Creditors, by their acceptance of the benefits hereof and of the other Security Documents, agrees and acknowledges that if the Lender Creditors receive (or are to receive) a distribution on account of undrawn amounts with respect to Letters of Credit issued under the Credit Agreement (which shall only occur after all outstanding Revolving Loans under the Credit Agreement and Unpaid Drawings have been paid in full), such amounts shall be paid to the Administrative Agent under the Credit Agreement and held by it, for the equal and ratable benefit of the Lender Creditors, as cash security for the repayment of Obligations owing to the Lender Creditors as such. If any amounts are held as cash security pursuant to the immediately preceding sentence, then upon the termination of all outstanding Letters of Credit under the Credit Agreement, and after the application of all such cash security to the repayment of all Obligations owing to the Lender Creditors after giving effect to the termination of all such Letters of Credit, if there remains any excess cash, such excess cash shall be returned by the Administrative Agent to the Collateral Agent for distribution in accordance with Section 5.6(a) hereof.

(e) All payments required to be made hereunder shall be made (x) if to the Lender Creditors, to the Administrative Agent for the account of the Lender Creditors, and (y) if to the Secured Hedging Creditors or the Treasury Services Creditors, to the trustee, paying agent or other similar representative (each, a “Representative”) for the Secured Hedging Creditors or the Treasury Services Creditors, as applicable, or, in the absence of such a Representative, directly to the Secured Hedging Creditors or the Treasury Services Creditors, as applicable.

(f) For purposes of applying payments received in accordance with this Section 5.6, the Collateral Agent shall be entitled to rely upon the Administrative Agent and (ii) the Representative or, in the absence of such a Representative, upon the Secured Hedging Creditors and the Treasury Services Creditors, as applicable, for a determination (which the Administrative Agent, each Representative, the Secured Hedging Creditors and the Treasury Services Creditors agree (or shall agree) to provide upon request of the Collateral Agent) of the outstanding Primary Obligations and Secondary Obligations owed to the Lender Creditors, the Secured Hedging Creditors or the Treasury Services Creditors, as the case may be. Unless it has received written notice from a Lender Creditor, a Secured Hedging Creditor or a Treasury Services Creditor to the contrary, the Administrative Agent and each Representative, in furnishing information pursuant to the preceding sentence, and the Collateral Agent, in acting hereunder, shall be entitled to assume that no Secondary Obligations are outstanding. Unless it has written notice from a Secured Hedging Creditor to the contrary, the Collateral Agent, in acting hereunder, shall be entitled to assume that no Secured Hedging Agreements are in existence.

(g) It is understood that the Assignors shall remain jointly and severally liable to the extent of any deficiency between the amount of the proceeds of the Collateral and the aggregate amount of the Obligations.

(h) It is understood and agreed by each Assignor and each Secured Creditor that the Collateral Agent shall have no liability for any determinations made by it in this

- 26 -

Section 5.6, in each case except to the extent resulting from the gross negligence or willful misconduct of the Collateral Agent (as determined by a court of competent jurisdiction in a final and non-appealable decision). Each Assignor and each Secured Creditor also agrees that the Collateral Agent may (but shall not be required to), at any time and in its sole discretion, and with no liability resulting therefrom, petition a court of competent jurisdiction regarding any application of Collateral in accordance with the requirements hereof, and the Collateral Agent shall be entitled to wait for, and may conclusively rely on, any such determination.

Section 5.7 Remedies Cumulative.

Each and every right, power and remedy hereby specifically given to the Collateral Agent shall be in addition to every other right, power and remedy specifically given to the Collateral Agent under this Agreement, the other Secured Debt Agreements or now or hereafter existing at law, in equity or by statute and each and every right, power and remedy whether specifically herein given or otherwise existing may be exercised from time to time or simultaneously and as often and in such order as may be deemed expedient by the Collateral Agent. All such rights, powers and remedies shall be cumulative and the exercise or the beginning of the exercise of one shall not be deemed a waiver of the right to exercise any other or others. No delay or omission of the Collateral Agent in the exercise of any such right, power or remedy and no renewal or extension of any of the Obligations shall impair any such right, power or remedy or shall be construed to be a waiver of any Default or Event of Default or an acquiescence thereof. No notice to or demand on any Assignor in any case shall entitle it to any other or further notice or demand in similar or other circumstances or constitute a waiver of any of the rights of the Collateral Agent to any other or further action in any circumstances without notice or demand. In the event that the Collateral Agent shall bring any suit to enforce any of its rights hereunder and shall be entitled to judgment, then in such suit the Collateral Agent may recover reasonable expenses, including reasonable attorneys’ fees, and the amounts thereof shall be included in such judgment.

Section 5.8 Discontinuance of Proceedings.

In case the Collateral Agent shall have instituted any proceeding to enforce any right, power or remedy under this Agreement by foreclosure, sale, entry or otherwise, and such proceeding shall have been discontinued or abandoned for any reason or shall have been determined adversely to the Collateral Agent, then and in every such case the relevant Assignor, the Collateral Agent and each holder of any of the Obligations shall be restored to their former positions and rights hereunder with respect to the Collateral subject to the security interest created under this Agreement, and all rights, remedies and powers of the Collateral Agent shall continue as if no such proceeding had been instituted.
