Upon delivery to the Administrative Agent, such additional Capital Stock shall be deemed to be part of the Collateral of such Pledgor and shall be subject to the terms of this Pledge Agreement whether or not Schedule 2.1(a) is amended to refer to such additional Capital Stock.

2.3 Delivery of the Collateral. Each Pledgor hereby agrees that:

	(a)		Delivery of Certificates. Each Pledgor shall deliver to the Administrative Agent (i) simultaneously with or prior to the execution and delivery of this Pledge Agreement, all certificates representing the Pledged Shares of such Pledgor and (ii) promptly upon the receipt thereof by or on behalf of a Pledgor, all other certificates and instruments constituting Collateral of a Pledgor. Prior to such delivery to the Administrative Agent, all such certificates and instruments constituting Collateral of a Pledgor shall be held in trust by such Pledgor for the benefit of the Administrative Agent pursuant hereto. All such certificates shall be delivered in suitable form for transfer by delivery or shall be accompanied by duly executed instruments of transfer or assignment in blank, substantially in the form provided in Schedule 2.3(a) attached hereto.

	(b)		Financing Statements. Each Pledgor authorizes the Administrative Agent to file one or more financing statements (with collateral descriptions broader, including without limitation “all assets” and/or “all personal property” collateral descriptions, and/or less specific than the description of the Collateral contained herein) disclosing the Administrative Agent’s security interest in the Collateral. Each Pledgor agrees to execute and deliver to the Administrative Agent such financing statements and other filings as may be reasonably requested by the Administrative Agent in order to perfect and protect the security interest created hereby in the Collateral of such Pledgor.

SECTION 3. Representations and Warranties. Each Pledgor represents and warrants to the Administrative Agent for the benefit of the holders of the Secured Obligations, that so long as any of the Secured Obligations remain outstanding and until all of the commitments relating thereto have been terminated:

3.1 Title. Such Pledgor owns or, with respect to Collateral acquired after the date hereof, such Pledgor will own, legally and beneficially, the Collateral free and clear of any Lien, security interest, pledge, claim, or other encumbrance or any right or option on the part of any third person to purchase or otherwise acquire the Collateral or any part thereof, except for the security interest granted hereunder and Permitted Liens. Such Pledgor has the unrestricted right to pledge the Collateral as contemplated hereby,

and there exists no “adverse claim” within the meaning of Section 8-102 of the UCC with respect to the Collateral.

3.2 Organization and Authority. Neither the execution, delivery or performance by such Pledgor of this Agreement nor compliance by it with the terms and provisions hereof, nor the consummation of the transactions contemplated herein, will (i) contravene any applicable provision of any law, statute, rule or regulation, or any order, writ, injunction or decree of any court or governmental instrumentality; or (ii) conflict with or result in any breach of any term, covenant, condition or other provision of, or constitute a default under, or (other than pursuant to the Collateral Documents) result in the creation or imposition of (or the obligation to create or impose) any Lien upon any of the property or assets of such Pledgor under the terms of any contractual obligation to which such Pledgor is a party or by which it or any of its properties or assets are bound or to which it may be subject.

3.3 First Priority Perfected Security Interest. This Agreement has been duly authorized, executed and delivered by such Pledgor. This Agreement creates a valid security interest in favor of the Administrative Agent for the benefit of the Lenders in the Collateral. The taking of possession by the Administrative Agent of the certificates representing the Pledged Shares and all other certificates and instruments constituting Collateral will perfect and establish the first priority of the Administrative Agent’s security interest in the Pledged Shares consisting of certificated securities and, when properly perfected by filing or registration, in all other Collateral represented by such Pledged Shares and instruments securing the Secured Obligations. Except as set forth in this Section 3.3 and except as may be required by applicable foreign laws affecting the pledge of Capital Stock of Foreign Subsidiaries, no action is necessary to perfect or otherwise protect such security interest.

3.4 Partnership and Membership Interests. Except as previously disclosed to the Administrative Agent, none of the Pledged Shares consisting of partnership or limited liability company interests (i) is dealt in or traded on a securities exchange or in a securities market, (ii) by its terms expressly provides that it is a security governed by Article 8 of the UCC, (iii) is an investment company security, (iv) is held in a securities account or (v) constitutes a Security or a Financial Asset (as each is defined in the UCC).

3.5 No Consent. No consent of, or notice to, any other Person and no authorization, approval or other action by, and no notice to or filing with, any governmental authority or regulatory body is required for the grant by such Pledgor of the Liens granted hereby or for the execution, delivery or performance of this Agreement by such Pledgor, other than the filing of financing statements and the filing of an investment act notice in connection with the stock of any Company organized in Canada and except for such other consents, notices or filings that have been obtained or made or that as of the date hereof are not required to have been obtained or made and may be obtained or made, as the case may be, when necessary.

SECTION 4. Covenants. Each Pledgor covenants and agrees that so long as any of the Secured Obligations remain outstanding and until all of the commitments relating thereto have been terminated:

4.1 Encumbrances. Except as permitted by the Credit Agreement, each Pledgor shall not create, permit, or suffer to exist, and shall defend the Collateral against, any Lien on the Collateral except the pledge and security interest of the Administrative Agent hereunder and except for Permitted Liens, and shall warrant and defend title to and ownership of the Collateral of such Pledgor at its own expense against the claims and demands of all other parties claiming an interest therein and defend such Pledgor’s rights in the Collateral and the Administrative Agent’s security interest in the Collateral against the claims of all persons and entities (other than any person or entity claiming by, through or under the Administrative Agent or any obligee of the Secured Obligations).

4.2 Sale of Collateral. No Pledgor shall sell, assign, or otherwise dispose of the Collateral or any part thereof except as permitted by the Credit Agreement.

4.3 Dividends. If any Pledgor shall become entitled to receive or shall receive any distribution (including, without limitation, any dividend or distribution in connection with any reclassification, increase, or reduction of capital or issued in connection with any reorganization), option or rights constituting Collateral, whether as an addition to, in substitution of, or in exchange for any Collateral or otherwise, such Pledgor agrees to accept the same as the Administrative Agent’s agent and to hold the same in trust for the Administrative Agent and to deliver the same (to the extent in form capable of delivery) promptly to the Administrative Agent in the exact form received, with the appropriate endorsement of such Pledgor when necessary, to be held by the Administrative Agent, as additional Collateral for the Secured Obligations, subject to the terms hereof. Any sums paid upon or in respect of the Collateral upon the liquidation or dissolution of the issuer thereof in violation of the Credit Agreement shall be paid over to the Administrative Agent to be held by it as additional Collateral for the Secured Obligations subject to the terms hereof except as otherwise provided in the Credit Agreement; and in case any distribution shall be made on or in respect of the Collateral while a Default or an Event of Default shall be continuing or any property shall be distributed while a Default or an Event of Default shall be continuing upon or with respect to the Collateral pursuant to any recapitalization or reclassification of the capital of the issuer thereof or pursuant to any reorganization of the issuer thereof, the property so distributed shall be delivered to the Administrative Agent to be held by it, as additional Collateral for the Secured Obligations, subject to the terms hereof. All sums of money and property so paid or distributed in respect of the Collateral that are received by such Pledgor shall, until paid or delivered to the Administrative Agent, be held by such Pledgor in trust as additional security for the Secured Obligations, provided that except to the extent that such sums of money or property have theretofore been applied against the Secured Obligations in accordance with the Credit Agreement, such sums of money or property shall forthwith be delivered to such Pledgor at such time as no Default or Event of Default shall be continuing under the Credit Agreement.

4.4 Further Assurances. At any time and from time to time, upon the request of the Administrative Agent, and at the sole expense of such Pledgor, such Pledgor shall promptly execute and deliver all such further instruments and documents and take such further action as the Administrative Agent may deem reasonably necessary or desirable to (a) preserve and perfect its security interest in the Collateral; (b) enable the Administrative Agent to exercise and enforce its rights and remedies hereunder in respect of the Collateral of such Pledgor; and (c) carry out the provisions and purposes of this Agreement, including, without limitation, (i) the execution and filing of such financing statements as the Administrative Agent may require and (ii) upon the occurrence and during the continuance of an Event of Default, if requested by the Administrative Agent, delivering to the Administrative Agent irrevocable proxies in respect of the Collateral of such Pledgor.

4.5 Inspection Rights. Upon reasonable notice from the Administrative Agent, each Pledgor shall permit the Administrative Agent and its representatives to examine, inspect, and copy such Pledgor’s books and records concerning ownership of the Collateral at any reasonable time during normal business hours and as often as the Administrative Agent may desire.

4.6 Books and Records. Each Pledgor shall xxxx its books and records (and shall cause the issuer of the Pledged Shares to xxxx its books and records) to reflect the security interest of the Administrative Agent for the benefit of the holders of the Secured Obligations under this Agreement.

4.7 Receipt after Default. If any Collateral is received by any Pledgor during the continuance of an Event of Default, such Pledgor shall pay over to the Administrative Agent all such Collateral on the

day received, including the cash and checks endorsed by such Pledgor evidencing the Collateral. Such Pledgor shall not commingle the Collateral with any other funds, proceeds or monies of such Pledgor, and shall keep such proceeds separate and apart from any other funds, proceeds or monies of such Pledgor and shall hold the Collateral in trust for the Administrative Agent until same shall be paid over to the Administrative Agent as agreed to herein.

4.8 Pledge of Shares of Controlled Foreign Corporation.

	(a)		In the event that the Collateral hereunder would, but for this Section 4.8(a), represent more than sixty-five percent (65%) of the Voting Stock of a Company which is a controlled foreign corporation, then the number of shares of Voting Stock of such Company in excess of such sixty-five percent (65%) automatically shall be released from the Lien of, and the terms and provisions of, this Agreement.

	(b)		In the event that the Collateral hereunder represents less than sixty-five percent (65%) of the Voting Stock of any Company which is a controlled foreign corporation (or, if less, 100% of the Voting Stock of such Company owned by the Pledgor), then such Pledgor will promptly pledge additional capital stock sufficient to increase the number of shares pledged hereunder to such sixty-five percent (65%) (or, if less, 100% of the Voting Stock of such Company owned by such Pledgor).

4.9 Amendments. Such Pledgor shall not make or consent to any amendment or other modification or waiver with respect to any of the Collateral of such Pledgor or enter into any agreement or allow to exist any restriction with respect to any of the Collateral of such Pledgor that is prohibited under the Credit Agreement or any other Loan Document.

4.10 Compliance with Securities Laws. Such Pledgor shall file all reports and other information now or hereafter required to be filed by such Pledgor with the United States Securities and Exchange Commission and any other state, federal or foreign agency in connection with such Pledgor’s ownership of the Collateral of such Pledgor.

4.11 Issuance or Acquisition of Capital Stock. Such Pledgor shall not, without executing and delivering, or causing to be executed and delivered, to the Administrative Agent such agreements, documents and instruments as the Administrative Agent may reasonably request for the purpose of perfecting its security interest therein, issue or acquire any Capital Stock constituting Collateral consisting of an interest in a partnership or a limited liability company that (i) is dealt in or traded on a securities exchange or in a securities market, (ii) by its terms expressly provides that it is a security governed by Article 8 of the UCC, (iii) is an investment company security, (iv) is held in a securities account or (v) constitutes a Security or a Financial Asset (as each is defined in the UCC).

SECTION 5. Rights of the Administrative Agent and Pledgor.

5.1 Power of Attorney. Each Pledgor hereby irrevocably and with the power of substitution constitutes and appoints the Administrative Agent on behalf of the holders of the Secured Obligations and any officer or agent thereof, with full power of substitution, as its true and lawful attorney-in-fact with full irrevocable power and authority in the place and stead and in the name of each Pledgor or in its own name, from time to time in the Administrative Agent’s discretion during the continuance of an Event of Default and prior to the Collateral Termination Date, to take any and all action and to execute any and all documents and instruments which may be necessary or desirable to accomplish the purposes of this Agreement and, without limiting the generality of the foregoing, hereby gives the Administrative Agent the power and right on behalf of the Pledgors and in its own name to do any of the following after the

occurrence and during the continuance of an Event of Default and to the extent permitted by applicable laws, without notice to or the consent of the Pledgors:

	(a)		to demand, xxx for, collect, or receive in the name of each Pledgor or in its own name, any money or property at any time payable or receivable on account of or in exchange for any of the Collateral and, in connection therewith, endorse checks, notes, drafts, acceptances, money orders, or any other instruments for the payment of money under the Collateral;

	(b)		to pay or discharge taxes, liens, security interests, or other encumbrances (other than Permitted Liens) levied or placed on or threatened against the Collateral;

	(c)		(i) to direct any parties liable for any payment under any of the Collateral to make payment of any and all monies due and to become due thereunder directly to the Administrative Agent or as the Administrative Agent shall direct, (ii) to receive payment of and receipt for any and all monies, claims, and other amounts due and to become due at any time in respect of or arising out of any Collateral; (iii) to sign and endorse any drafts, assignments, proxies, stock powers, verifications, notices, and other documents relating to the Collateral; (iv) to commence and prosecute any suit, actions or proceedings at law or in equity in any court of competent jurisdiction to collect the Collateral or any part thereof and to enforce any other right in respect of any Collateral; (v) to defend any suit, action, or proceeding brought against any Pledgor with respect to any Collateral; (vi) to settle, compromise, or adjust any suit, action, or proceeding described in clause (v) above and, in connection therewith, to give such discharges or releases as the Administrative Agent may deem appropriate; (vii) to exchange any of the Collateral for other property upon any merger, consolidation, reorganization, recapitalization, or other readjustment of the issuer thereof and, in connection therewith, deposit any of the Collateral with any committee, depositary, transfer agent, registrar, or other designated agency upon such terms as the Administrative Agent may determine; (viii) to add or release any guarantor, endorser, surety, or other party to any of the Collateral or the Secured Obligations; (ix) to sell, transfer, pledge, make any agreement with respect to or otherwise deal with any of the Collateral as fully and completely as though the Administrative Agent were the absolute owner thereof for all purposes, and to do, at the Administrative Agent’s option and such Pledgor’s expense, at any time, or from time to time, all acts and things which the Administrative Agent deems necessary to protect, preserve, or realize upon the Collateral and the Administrative Agent’s security interest; (x) to execute and deliver all assignments, conveyances, statements, financing statements, renewal financing statements, security and pledge agreements, affidavits, notices and other agreements, instruments and documents that the Administrative Agent may reasonably deem appropriate in order to perfect and maintain the security interests and liens granted in this Agreement and in order to fully consummate all of the transactions contemplated herein; and (xi) to vote for a shareholder resolution, or to sign an instrument in writing, sanctioning the transfer of any or all of the Collateral into the name of the Administrative Agent or one or more of the holders of the Secured Obligations or into the name of any transferee to whom the Collateral or any part thereof may be sold pursuant to Section 6.2 hereof.

This power of attorney is a power coupled with an interest and shall be irrevocable. The Administrative Agent shall be under no duty to exercise or withhold the exercise of any of the rights, powers, privileges, and options expressly or implicitly granted to the Administrative Agent in this Agreement, and shall not be liable for any failure to do so or any delay in doing so. The Administrative Agent shall not be liable for any act or omission or for any error of judgment or any mistake of fact or law in its individual capacity or in its capacity as attorney-in-fact except acts or omissions constituting or resulting from its willful misconduct or gross negligence. This power of attorney is conferred on the Administrative Agent solely to protect, preserve, and realize upon its security interest in the Collateral.

5.2 Voting Rights. Until written notice shall be given to the Pledgors in accordance with Section 6.2(d) that the Administrative Agent has exercised its rights under Section 6.2(d) to vote the Collateral (provided, however, if the Administrative Agent is prevented from providing such notice as a result of Section 362 of the United States Bankruptcy Code or similar law the Pledgors shall be entitled to exercise such rights so long as no Event of Default shall have occurred and be continuing), a Pledgor shall be entitled to exercise any and all voting and other rights relating or pertaining to the Collateral or any part thereof and the Administrative Agent shall execute and deliver (or cause to be executed and delivered) to such Pledgor all such proxies and other instruments as such Pledgor may reasonably request for the purpose of enabling such Pledgor to exercise the voting and other rights which it is entitled to exercise pursuant to this sentence.

5.3 Collateral Proceeds. Until written notice shall be given to the Pledgors in accordance with Section 6.2(d) that the Administrative Agent has exercised its rights under Section 6.2(d) to vote the Collateral, each Pledgor shall be entitled to receive and collect for its own use all Collateral Proceeds.

5.4 Performance by the Administrative Agent of the Pledgors’ Obligations. If an Event of Default has occurred and is continuing or if a Pledgor fails to perform or comply with any of its agreements contained herein, the Administrative Agent may perform or cause performance of or compliance with such agreement and in so doing may expend such sums as the Administrative Agent may reasonably deem advisable in the performance thereof. All such expenses of the Administrative Agent so expended, together with interest thereon at the rate of interest provided in the Credit Agreement, shall be payable by the Pledgors on a joint and several basis to the Administrative Agent on demand and shall constitute Secured Obligations secured by this Agreement.

5.5 The Administrative Agent’s Duty of Care. Other than the exercise of reasonable care in the physical custody of the Collateral while held by the Administrative Agent hereunder, the Administrative Agent shall have no responsibility for or obligation or duty with respect to all or any part of the Collateral or any matter or proceeding arising out of or relating thereto, including, without limitation, any obligation or duty to collect any sums due in respect thereof or to protect or preserve any rights against prior parties or any other rights pertaining thereto, it being understood and agreed that Pledgor shall be responsible for preservation of all rights in the Collateral. Without limiting the generality of the foregoing, the Administrative Agent shall be conclusively deemed to have exercised reasonable care in the custody of the Collateral if the Administrative Agent takes such action, for purposes of preserving rights in the Collateral, as Pledgor may reasonably request in writing, but no failure or omission or delay by the Administrative Agent in complying with any such request by Pledgor, and no refusal by the Administrative Agent to comply with any such request by Pledgor, shall of itself be deemed to be a failure to exercise reasonable care.

SECTION 6. Events of Default and Remedies.

6.1 Events of Default. The Pledgors shall be in default under this Agreement upon the occurrence of and during the continuation of any of the events or conditions defined as Events of Default in the Credit Agreement (an “Event of Default”).

6.2 Rights and Remedies. Prior to the Collateral Termination Date, upon the occurrence of an Event of Default and so long as the same shall be continuing, the Administrative Agent shall have the following rights and remedies to the extent not prohibited by applicable laws:

	(a)		In addition to all other rights and remedies granted to the Administrative Agent in this Agreement and in any other instrument or agreement securing, evidencing, or relating to the Secured Obligations, the Administrative Agent shall have all of the rights and remedies of a secured party under the UCC of the jurisdiction applicable to the affected Collateral. Without limiting the generality of the foregoing, the Administrative Agent may (i) without demand or notice to the Pledgors, collect, receive, or take possession of the Collateral or any part thereof, (ii) sell or otherwise dispose of the Collateral, or any part thereof, in one or more parcels at public or private sale or sales, at the Administrative Agent’s offices or elsewhere, for cash, on credit, or for future delivery without assumption of any credit risk, and/or (iii) bid and become a purchaser at any such sale free of any right or equity of redemption in any of the Pledgors, which right or equity is hereby expressly waived and released by all of the Pledgors. Upon the request of the Administrative Agent, any of the Pledgors shall assemble the Collateral and make it available to the Administrative Agent at any place designated by the Administrative Agent that is reasonably convenient to such Pledgor and the Administrative Agent. Each of the Pledgors agrees that the Administrative Agent shall not be obligated to give more than ten (10) days’ prior written notice of the time and place of any public sale or of the time after which any private sale may take place and that such notice shall constitute reasonable notice of such matters. Each of the Pledgors shall be liable, jointly and severally, for all reasonable expenses of retaking, holding, preparing for sale, or the like, and all reasonable attorneys’ fees and other reasonable expenses incurred by the Administrative Agent in connection with the collection of the Secured Obligations and the enforcement of the Administrative Agent’s rights under this Agreement, in each case during the continuance of an Event of Default, all of which expenses and fees shall constitute additional Secured Obligations secured by this Agreement. The Administrative Agent may apply the Collateral against the Secured Obligations then due and payable in such order and manner as it shall elect in its sole discretion. Each of the Pledgors shall remain liable for any deficiency (subject to Section 7.16 hereof) together with interest thereon at the Default Rate if the proceeds of any sale or disposition of the Collateral are insufficient to pay the Secured Obligations. Each of the Pledgors waives all rights of marshaling in respect of the Collateral.

	(b)		The Administrative Agent may cause any or all of the Collateral held by it to be transferred into the name of the Administrative Agent or the name or names of the Administrative Agent’s nominee or nominees (in each case as pledgee hereunder).

	(c)		The Administrative Agent shall be entitled to receive all dividends and cash distributions payable in respect of the Collateral. Pledgor shall execute notice letters, in form and substance satisfactory to the Administrative Agent (as and when requested by the Administrative Agent), notifying the Company or Companies of the fact of this Agreement and directing the Company or Companies to make payment directly to the Administrative Agent of all of the distributions which are due and owing to Pledgor by the Company or Companies, and directing the Company or Companies to accompany each transmission of such distributions to the Administrative Agent with a report in such form as the Administrative Agent may reasonably require in order to identify (i) the type of distribution being made, and (ii) the calculations made by the Company or Companies to determine the amount of the distribution distributed to the Administrative Agent.

	(d)		The Administrative Agent shall have the right, but shall not be obligated to, exercise or cause to be exercised all voting rights and powers in respect of the Collateral, and Pledgor shall deliver to the Administrative Agent, if requested by the Administrative Agent, irrevocable proxies with respect to the Collateral in form satisfactory to the Administrative Agent.

Because of applicable securities laws, including without limitation, the Securities Act of 1933, as amended, and other applicable state securities laws, there may be legal restrictions or limitations affecting attempts of the Administrative Agent to dispose of the Collateral in the enforcement of its rights and remedies hereunder, the Administrative Agent is hereby authorized by the Pledgors, but not obligated, upon the occurrence and during the continuance of an Event of Default, to the extent permitted by applicable law, to sell all or any part of the Collateral at private sale, subject to investment letters or in any other manner which will not require the Collateral or any part thereof, to be registered in accordance with the Securities Act of 1933, as amended, or the rules and regulations promulgated thereunder, or any other applicable securities law or regulation. The Pledgors specifically agree that under these circumstances, such a sale is a commercially reasonable method of disposition of the Collateral. The Administrative Agent is also hereby authorized by the Pledgors, but not obligated, to take such actions, give such notices, obtain such rulings and consents, and do such other things as the Administrative Agent may deem appropriate in the event of such a sale or disposition of any of the Collateral. The Pledgors acknowledge that the Administrative Agent may, in its reasonable discretion, approach a restricted number of potential purchasers and that a sale under such circumstances may yield a lower price for the Collateral or any part or parts thereof than would otherwise be obtainable if the same were registered and sold in the open market, the Pledgors agrees that such private sale shall constitute a commercially reasonable method of disposing of the Collateral in view of the time, expense, and potential liability to the parties of such transactions of registration of the Collateral in accordance with applicable securities laws.

6.3 Application of Proceeds. Upon the occurrence and during the continuation of an Event of Default, any payments in respect of the Secured Obligations and any proceeds of the Collateral, when received by the Administrative Agent or any of the holders of the Secured Obligations in cash or its equivalent, will be applied in reduction of the Secured Obligations in the order set forth in the Credit Agreement.

SECTION 7. Miscellaneous.

7.1 No Waiver; Cumulative Remedies. No failure on the part of the Administrative Agent to exercise and no delay in exercising, and no course of dealing with respect to, any right, power, privilege or remedy under this Agreement shall operate as a waiver thereof, nor shall any single or partial exercise

of any right, power, privilege or remedy under this Agreement preclude any other or further exercise thereof or the exercise of any other right, power, privilege or remedy. To the fullest extent permitted by applicable laws, the rights, powers, privileges and remedies provided for in this Agreement are cumulative and not exclusive of any rights, powers, privileges and remedies provided by law. The Administrative Agent may exercise any right, power, privilege or remedy under this Agreement or under applicable law against any Pledgor without enforcing any rights, powers, privileges or remedies against any other Pledgor under this Agreement or otherwise, each of the Pledgors expressly waiving any rights or requirements that the Administrative Agent or any Lender first enforce any right, power, privilege or remedy against the Borrower, any other Pledgor or any other Collateral for the Secured Obligations.

7.2 Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of each Pledgor and the Administrative Agent for the benefit of the holders of the Secured Obligations and their respective heirs, successors, and assigns, except that none of the Pledgors may assign any of its rights or obligations under this Agreement without the prior written consent of the Required Lenders under the Credit Agreement except to the extent permitted by the Credit Agreement. To the fullest extent permitted by law, each Pledgor hereby releases the Administrative Agent and each holder of the Secured Obligations, and their respective successors and assigns, from any liability for any act or omission relating to this Agreement or the Collateral, except for any liability arising from the gross negligence or willful misconduct of the Administrative Agent or such holder, or their respective officers, employees or agents.

7.3 Notices. All notices required or permitted to be given under this Agreement shall be given as provided in Section 11.02 of the Credit Agreement.
