(i)            create, preserve, perfect, confirm or validate the Transaction Liens on the Collateral;

(ii)           enable the Collateral Agent and the other Secured Parties to obtain the full benefits of the Security Documents; or

To the extent permitted by applicable law, the Lien Grantor authorizes the Collateral Agent to execute and file such financing statements or financing change statements as may be necessary or appropriate to reflect the security interests granted by this Agreement. The Collateral Agent shall provide the Lien Grantor with copies of any such financing statements and financing change statements. The Lien Grantor agrees that a photocopy or other reproduction of this Agreement or of a financing statement is sufficient as a financing statement to the extent permitted by law. The Lien Grantor constitutes the Collateral Agent its attorney-in-fact to execute and file all filings required or so requested for the foregoing purposes, all acts of such attorney being hereby ratified and confirmed; and such power, being coupled with an interest, shall be irrevocable until all the Transaction Liens granted by the Lien Grantor terminate pursuant to Section 12.

(b)            The Lien Grantor will not (i) change its name or structure as a corporation, (ii) change its jurisdiction of organization, incorporation or amalgamation or the location of its principal place of business or chief executive office (or, if the Lien Grantor is domiciled in Quebec, domicile for the purposes of the Quebec Civil Code) from the jurisdictions listed in its Perfection Certificate or (iii) change, or add to, the locations of Collateral listed in its Perfection Certificate, other than Inventory that is in transit in the ordinary course of the Lien Grantor’s business, unless, in each case, it shall have given the Collateral Agent 30 days prior written notice thereof and delivered an Opinion of Counsel with respect thereto in accordance with Section 4(c).

(c)            Within 10 days after it takes any action contemplated by Section 4(b), the Lien Grantor, at its own expense, will cause to be delivered to the Collateral Agent an Opinion of Counsel, in form and substance reasonably satisfactory to the Collateral Agent, to the effect that (i) all financing statements, financing change statements and amendments or supplements thereto, and other documents required to be filed or recorded in order to perfect and protect the Transaction Liens against all creditors of and purchasers from the Lien Grantor after it takes such action have been filed or recorded in each office necessary for such purpose, (ii) all fees and taxes, if any, payable in connection with such filings or recordings have been paid in full and (iii) except as otherwise agreed by the Required Lenders, such action will not adversely affect the perfection or priority of the Transaction Lien on any Collateral to be owned by the Lien Grantor after it takes such action or the accuracy of the Lien Grantor’s representations and warranties herein relating to such Collateral.

(d)            The Lien Grantor will not sell, lease, exchange, assign or otherwise dispose of, or grant any option with respect to, any of its Collateral; provided that the Lien Grantor may do any of the foregoing unless (i) doing so would breach a covenant in the Credit Agreement (including, for the avoidance of doubt, the last sentence of Section 5.02(c) of the Credit Agreement) or (ii) an Event of Default shall have occurred and be continuing and the Collateral Agent shall have notified the Lien Grantor that its right to do so is terminated, suspended or otherwise limited. Concurrently with any sale or other disposition (except a lease) permitted by the foregoing proviso, the Transaction Liens on the assets sold or disposed of (but not in any Proceeds arising from such sale or disposition) will cease immediately without any action by the Collateral Agent or any other Secured Party. The Collateral Agent will, at the Borrower’s expense, execute and deliver to the Lien Grantor such documents as the Lien Grantor shall reasonably request to evidence the fact that any asset so sold or disposed of is no longer subject to a Transaction Lien.

(e)            The Lien Grantor will use commercially reasonable efforts to cause to be collected from its account debtors, when due, all amounts owing under its Receivables (including delinquent Receivables, which will be collected in accordance with lawful collection procedures) and will apply all amounts collected thereon, forthwith upon receipt thereof, to the outstanding balances of such Receivables. Subject to the rights of the Collateral Agent hereunder if an Event of Default shall have occurred and be continuing, the Lien Grantor may allow in the ordinary course of business as adjustments to amounts owing under its Receivables (but without limiting the effect of the definition of “Ineligible Receivables” contained in the Credit Agreement) (i) any extension or renewal of the time or times for payment, or settlement for less than the total unpaid balance, that the Lien Grantor finds appropriate in accordance with sound business judgment and (ii) refunds or credits, all in the ordinary course of business and consistent with the Lien Grantor’s historical collection practices. The costs and expenses (including reasonable and documented attorney’s fees) of collection, whether incurred by the Lien Grantor or the Collateral Agent, shall be paid by the Lien Grantor. If an Event of Default shall have occurred and be continuing, the Lien Grantor will, if requested to do so by the Collateral Agent, promptly notify (and the Lien Grantor authorizes the Collateral Agent to so notify) each account debtor in respect of its Receivables that such Receivables have been assigned to the Collateral Agent hereunder, and that any payments due or to become due in respect of such Receivables are to be made directly to the Collateral Agent.

(f)            The Lien Grantor will, promptly upon request, provide to the Collateral Agent all information and evidence concerning the Collateral that the Collateral Agent may reasonably request from time to time to enable it to enforce the provisions of the Security Documents.

Subject to the provisions of the instrument appointing a Receiver, any such Receiver shall (i) have such powers as have been granted to the Collateral Agent under this Section 6, and (ii) shall be entitled to exercise such powers at any time that such powers would otherwise be exercisable by the Collateral Agent under this Section 6, which powers shall include the power to take possession of the Canadian Collateral, to preserve the Canadian Collateral or its value, and to sell, lease, license or otherwise dispose of or concur in selling, leasing, licensing or otherwise disposing of the Canadian Collateral. To facilitate the foregoing powers, any such Receiver may, to the exclusion of all others, including such Lien Grantor, enter upon and occupy all premises in Canada owned or occupied by such Lien Grantor wherein the Canadian Collateral may be situated, maintain the Canadian Collateral upon such premises. Except as may be otherwise directed by the Collateral Agent, all money received from time to time by such Receiver in carrying out its appointment shall be received in trust for and be paid over to the Collateral Agent, and any surplus shall be applied in accordance with the requirements of applicable law.

(b)            In making the payments and allocations required by this Section, the Collateral Agent may rely upon information supplied to it pursuant to Section 11(g).

Section 8. Fees and Expenses; Indemnification.

(a)            The Lien Grantor will forthwith upon demand pay to the Collateral Agent:

(i)            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;

(ii)           the amount of any and all reasonable and documented out-of-pocket expenses, including transfer taxes and reasonable and documented fees and expenses of counsel and other experts, that the Collateral Agent may incur in connection with (x) the administration or enforcement of the Security Documents, including such expenses as are incurred to preserve the value of the Collateral or the validity, perfection, rank or value of any Transaction Lien, (y) the collection, sale or other disposition of any Collateral or (z) 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 Lien Grantor 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 and documented fees and 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 to the extent that such loss, liability or expense arises from the Collateral Agent’s gross negligence or willful misconduct or a breach of any duty that the Collateral Agent has under this Agreement (after giving effect to Sections 10 and 11).

Any such amount not paid to the Collateral Agent on demand will bear interest for each day thereafter until paid at a rate per annum equal to the sum of 2.00% plus the Base Rate for such day plus the Applicable Rate that would, in the absence of an Event of Default, be applicable to the Base Rate Loans for such day.

(b)            If any transfer tax, documentary stamp tax or other tax is payable in connection with any transfer or other transaction provided for in the Security Documents, the Lien Grantor will pay such tax and provide any required tax stamps to the Collateral Agent or as otherwise required by law.

Section 9. Authority to Administer Collateral.The Lien Grantor irrevocably appoints the Collateral Agent its true and lawful attorney, with full power of substitution, in the name of the Lien Grantor, any Secured Party or otherwise, for the sole use and benefit of the Secured Parties, but at the Lien Grantor’s expense, to the extent permitted by law to exercise, at any time and from time to time while an Event of Default shall have occurred and be continuing, all or any of the following powers with respect to all or any of the Collateral (to the extent necessary to pay the Secured Obligations in full):

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

(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 Lien Grantor at least fifteen 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 contain the information specified in the PPSA; provided that, if the Collateral Agent fails to comply with this sentence in any respect, its liability for such failure shall be limited to the liability (if any) imposed on it as a matter of law under the PPSA.

Section 10. 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 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 or by reason of any act or omission by the Collateral Agent pursuant to instructions from the Administrative Agent, except to the extent that such liability arises from the Collateral Agent’s gross negligence or willful misconduct.

The Collateral Agent may rely conclusively on advice from the Administrative Agent as to whether at any time (i) an Event of Default under the Credit Agreement has occurred and is continuing, (ii) the maturity of the Loans has been accelerated or (iii) any proposed action is permitted or required by the Credit Agreement.

(f)            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. The Collateral Agent and any such sub-agent may perform any of its duties and exercise any of its rights and powers through its Related Parties. The exculpatory provisions of Section 10 and this Section shall apply to any such sub-agent and to the Related Parties of the Collateral Agent and any such sub-agent.

(g)            Information as to Secured Obligations and Actions by Secured Parties.

(i)             The Collateral Agent may refuse to act on any notice, consent, direction or instruction from the Administrative Agent or 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, (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, or instructed the Agent to give, such notice, consent, direction or instruction) or (iii) is unduly prejudicial to Secured Parties not joining in such notice, consent, direction or instruction.

(j)             Resignation; Successor Collateral Agent.

If no successor shall have been so appointed by the Required 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 which shall be a bank with an office in the United States, 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 the Lien Grantor to a successor Collateral Agent shall be the same as those payable to its predecessor unless otherwise agreed by the Lien Grantor and such successor. After the Collateral Agent’s resignation hereunder, the provisions of this Section and Section 10 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.

In each case, such termination shall not require the consent of any Secured Party, and the Collateral Agent and any third party shall be fully protected in relying on a certificate of the Lien Grantor as to whether any Pledged Receivables qualify as Transferred Receivables (including whether the transfer thereof is permitted under the Credit Agreement and this Agreement).

(c)            If the Borrower delivers a certificate pursuant to Section 12(b) stating that any Pledged Receivables qualify as Transferred Receivables, the Collateral Agent and any third party shall be fully protected in relying on such certificate as conclusive proof that the Transferred Receivables are not Collateral.

(d)            At any time before the Transaction Liens terminate, the Collateral Agent may, at the written request of the Lien Grantor, (i) release any Collateral (but not all or substantially all of the Collateral) with the prior written consent of the Required Lenders or (ii) release all or substantially all of the Collateral with the prior written consent of all the Lenders.
