(ii) each Pledgor shall cause, and hereby authorizes the Pledgee to cause, appropriate financing statements (on appropriate forms) under the Uniform Commercial Code as in effect in the various relevant States, covering all Collateral hereunder (with the form of such financing statements to be reasonably satisfactory to the Pledgee), to be filed in the relevant filing offices so that at all times the Pledgee’s security interest in all Investment Property and other Collateral which can be perfected by the filing of such financing statements (in each case to the maximum extent perfection by filing may be obtained under the laws of the relevant States, including, without limitation, Section 9-312(a) of the UCC) is so perfected. Notwithstanding the foregoing, if reasonably requested by any Pledgor, the Pledgee shall, at such Pledgor’s expense, make such filings as may be reasonably requested to evidence that the security interests hereunder do not attach to any property that is excluded from the Collateral pursuant to the proviso in Section 3.1 hereof.

3.3. Subsequently Acquired Collateral. If any Pledgor shall acquire (by purchase, stock dividend, distribution or otherwise) any additional Collateral at any time or from time to time after the date hereof, such Collateral shall automatically (and without any further action being required to be taken) be subject to the pledge and security interests created pursuant to Section 3.1 hereof and, furthermore, such Pledgor will thereafter take (or cause to be taken) all action (as promptly as practicable and, in any event, within 30 days after it obtains such Collateral) with respect to such Collateral in accordance with the procedures set forth in Section 3.2 hereof, and will (i) with respect to any Collateral other than Equity Interests issued by (A) a Foreign Subsidiary (other than a Canadian Subsidiary or a Subsidiary organized under the laws of Luxembourg or the United Kingdom) of the Company that is not a Material Subsidiary or (B) a Person that is not a Subsidiary and is organized under the laws of a foreign jurisdiction, promptly thereafter deliver to the Pledgee a certificate executed by an authorized officer of such Pledgor describing such Collateral and certifying that the same has been duly pledged in favor of the Pledgee (for the benefit of the Secured Creditors) hereunder and (ii) promptly thereafter (or in the case of any Equity Interests issued by (A) a Foreign Subsidiary (other than a Canadian Subsidiary or a Subsidiary organized under the laws of Luxembourg or the United Kingdom) of the Company that is not a Material Subsidiary or (B) a Person that is not a Subsidiary and is organized under the laws of a foreign jurisdiction, at the time of delivery of any compliance certificate required to be delivered pursuant to Section 9.01(d) of the Credit Agreement) deliver to the Pledgee supplements to Annexes A through G hereto as are necessary to cause such Annexes to be complete and accurate at such time. Without limiting the foregoing, each Pledgor shall be required to pledge hereunder in accordance with the terms hereof the Equity Interests of any Foreign Subsidiary at any time and from time to time after the date hereof acquired by such Pledgor, provided that (x) any such pledge of Voting Equity Interests of any Foreign Subsidiary shall be subject to the provisions of clause (x) of the proviso to Section 3.1 hereof and (y) each Pledgor shall be required to pledge hereunder 100% of the Non-Voting Equity Interests of each Foreign Subsidiary at any time and from time to time acquired by such Pledgor.

3.4. Transfer Taxes. Each pledge of Collateral under Section 3.1 or Section 3.3 hereof shall be accompanied by any transfer tax stamps required in connection with the pledge of such Collateral.

3.5. Certain Representations and Warranties Regarding the Collateral. Each Pledgor represents and warrants that on the date hereof: (i) each Subsidiary of such Pledgor, and the direct ownership thereof, is listed in Annex B hereto; (ii) the Stock (and any warrants or options to purchase Stock) of each Subsidiary held by such Pledgor consists of the number and type of shares of the stock (or warrants or options to purchase any stock) of the corporations as described in Annex C hereto; (iii) such Stock referenced in clause (ii) of this paragraph constitutes that percentage of the issued and outstanding capital stock of the issuing corporation as is set forth in Annex C hereto; (iv) the Notes with a value equal to $1,000,000 or more held by such Pledgor consist of the promissory notes described in Annex D hereto where such Pledgor is listed as the lender; (v) the Limited Liability Company Interests of each Subsidiary held by such Pledgor consist of the number and type of interests of the Persons described in Annex E hereto; (vi) each such Limited Liability Company Interest referenced in clause (v) of this paragraph constitutes that percentage of the issued and outstanding equity interest of the issuing Person as set forth in Annex

3.6. Conflicts with Foreign Pledge Agreements. To the extent that there is any overlap between, or conflict with, the provisions of this Agreement and any Foreign Pledge Agreement, such Foreign Pledge Agreement shall prevail with respect only to (i) any provision relating to the pledged collateral described in and covered under such Foreign Pledge Agreement and (ii) any provision where adherence to the law governing such Foreign Pledge Agreement is required for such Foreign Pledge Agreement to be enforceable in accordance with its terms.

4. APPOINTMENT OF SUB-AGENTS; ENDORSEMENTS, ETC. The Pledgee shall have the right to appoint one or more sub-agents for the purpose of retaining physical possession of the Collateral, which may be held (in the discretion of the Pledgee) in the name of the relevant Pledgor, endorsed or assigned in blank or in favor of the Pledgee or any nominee or nominees of the Pledgee or a sub-agent appointed by the Pledgee.

5. VOTING, ETC., WHILE NO EVENT OF DEFAULT OR SPECIFIED DEFAULT. Unless and until there shall have occurred and be continuing an Event of Default, each Pledgor 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 Agreement, or in a manner adverse to the interests of the Pledgee or any other Secured Creditor in the Collateral in any material respect, unless permitted by the terms of the Secured Debt Agreements. All such rights of each Pledgor to vote and to give consents, waivers and ratifications shall cease following written notice from the Pledgee 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 7 hereof shall become applicable.

6. DIVIDENDS AND OTHER DISTRIBUTIONS. Unless and until there shall have occurred and be continuing an Event of Default and following written notice from the Pledgee (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 Pledgor. The Pledgor shall be entitled to receive directly, subject to the other terms of this Agreement:

(i) all other or additional stock, notes, certificates, limited liability company interests, 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;

Page #PageNum#

(ii) all other or additional stock, notes, certificates, limited liability company interests, partnership interests, instruments or other securities or property (including, but not limited to, cash subject to the first sentence of this Section 6) 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 interests, 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, merger, exchange of stock, conveyance of assets, liquidation or similar corporate or other reorganization.

All cash dividends, cash distributions or other cash payments which are received by any Pledgor contrary to the provisions of this Section 6 or Section 7 hereof shall be received in trust for the benefit of the Pledgee, shall be segregated from other property or funds of such Pledgor and shall be promptly paid over to the Pledgee as Collateral in the same form as so received (with any necessary endorsement).

7. REMEDIES IN CASE OF AN EVENT OF DEFAULT. If there shall have occurred and be continuing an Event of Default, then and in every such case, the Pledgee shall be entitled to exercise all of the rights, powers and remedies (whether vested in it by this Agreement, any other Secured Debt Agreement or by law) for the protection and enforcement of its rights in respect of the Collateral, and the Pledgee shall be entitled to exercise all the rights and remedies of a secured party under the UCC as in effect in any relevant jurisdiction and also shall be entitled, without limitation, to exercise the following rights, which each Pledgor hereby agrees to be commercially reasonable:

(i) Following written notice to such Pledgor (provided that no such notice shall be required if any Event of Default under Section 11.05 has occurred and is continuing), to receive all amounts payable in respect of the Collateral otherwise payable under Section 6 hereof to such Pledgor;

(ii) to transfer all or any part of the Collateral into the Pledgee’s name or the name of its nominee or nominees;

(iii) to accelerate any Pledged Note which may be accelerated in accordance with its terms, and take any other lawful action to collect upon any Pledged Note (including, without limitation, to make any demand for payment thereon);

(iv) to 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;

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

Page #PageNum#

(vi) to vote (and exercise all rights and powers in respect of voting) all or any part of the Collateral (whether or not transferred into the name of the Pledgee) and give all consents, waivers and ratifications in respect of the Collateral and otherwise act with respect thereto as though it were the outright owner thereof (each Pledgor hereby irrevocably constituting and appointing the Pledgee the proxy and attorney-in-fact of such Pledgor, with full power of substitution to do so);

(vii) at any time and from time to time to sell, assign and deliver, or grant options to purchase, all or any part of the Collateral, or any interest therein, at any public or private sale, without demand of performance, advertisement or, notice of intention to sell or of the time or place of sale or adjournment thereof or to redeem or otherwise purchase or dispose (all of which are hereby waived by each Pledgor), for cash, on credit or for other property, for immediate or future delivery without any assumption of credit risk, and for such price or prices and on such terms as the Pledgee in its absolute discretion may determine, provided at least 10 days’ written notice of the time and place of any such sale shall be given to the respective Pledgor. The Pledgee shall not be obligated to make any such sale of Collateral regardless of whether any such notice of sale has theretofore been given. Each Pledgor hereby waives and releases to the fullest extent permitted by law any right or equity of redemption with respect to the Collateral, whether before or after sale hereunder, and all rights, if any, of marshalling the Collateral and any other security or the Obligations or otherwise. At any such sale, unless prohibited by applicable law, the Pledgee on behalf of the Secured Creditors may bid for and purchase all or any part of the Collateral so sold free from any such right or equity of redemption. Neither the Pledgee nor any other Secured Creditor shall be liable for failure to collect or realize upon any or all of the Collateral or for any delay in so doing nor shall any of them be under any obligation to take any action whatsoever with regard thereto; and

(viii) to set off any and all Collateral against any and all Obligations, and to withdraw any and all cash or other Collateral from any and all Collateral Accounts and to apply such cash and other Collateral to the payment of any and all Obligations.

8. REMEDIES, CUMULATIVE, ETC. Each and every right, power and remedy of the Pledgee provided for in this Agreement or in any other Secured Debt Agreement, or now or hereafter existing at law or in equity or by statute shall be cumulative and concurrent and shall be in addition to every other such right, power or remedy. The exercise or beginning of the exercise by the Pledgee or any other Secured Creditor of any one or more of the rights, powers or remedies provided for in this Agreement or any other Secured Debt Agreement or now or hereafter existing at law or in equity or by statute or otherwise shall not preclude the simultaneous or later exercise by the Pledgee or any other Secured Creditor of all such other rights, powers or remedies, and no failure or delay on the part of the Pledgee or any other Secured Creditor to exercise any such right, power or remedy shall operate as a waiver thereof. No notice to or demand on any Pledgor 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 Pledgee or any other Secured Creditor to any other or further action in any circumstances without notice or demand. The Secured Creditors agree that

Page #PageNum#

this Agreement may be enforced only by the action of the Pledgee, 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 Pledgee for the benefit of the Secured Creditors upon the terms of this Agreement and the other Security Documents.

9. RECEIVER’S POWERS. (a) Any receiver appointed by the Pledgee pursuant to Section 7 hereof is vested with the rights and remedies which could have been exercised by the Pledgee in respect of any Pledgor 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 Pledgee.

(b) Any receiver appointed by the Pledgee pursuant to Section 7 hereof will act as agent for the Pledgee for the purposes of taking possession of the Collateral, but otherwise and for all other purposes (except as provided below), as agent for the Pledgors. The receiver may sell, lease, or otherwise dispose of Collateral in accordance with the terms hereof as agent for the Pledgors or as agent for the Pledgee as the Pledgee may determine in its discretion. Each Pledgor agrees to ratify and confirm all actions of the receiver acting as agent for such Pledgor so long as such actions are taken in accordance with the terms hereof.

(c) The Pledgee, in appointing or refraining from appointing any receiver, does not incur liability to the receiver, the Pledgors or otherwise and is not responsible for any misconduct or negligence of such receiver except to the extent resulting from the gross negligence or willful misconduct of the Pledgee (as determined by a court of competent jurisdiction in a final and non-appealable decision) (it being agreed that appointing or refraining to appoint any receiver in the reasonable judgment of the Pledgee’s or based on the advice of advisors or counsel shall not constitute gross negligence or willful misconduct).

10. 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 Pledgor 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 Pledgee, 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 Pledgor 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 Pledgor would if such ULC Shares were not pledged to the Pledgee 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 Pledgee, any of the Secured Creditors or any Person other than a Pledgor, 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 Pledgor and further steps are taken

Page #PageNum#

hereunder or thereunder so as to register the Pledgee, 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 Pledgee 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 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 if there shall have occurred and be continuing an Event of Default, no Pledgor shall cause or permit, or enable any ULC in which it holds ULC Shares that are Collateral to cause or permit, the Pledgee 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 Pledgee 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.

11. APPLICATION OF PROCEEDS. (a) All monies collected by the Pledgee upon any sale or other disposition of, any collection from, or other realization upon all or any part of, the Collateral (whether or not expressly characterized as such) in connection with the exercise of its rights and remedies in accordance with this Agreement, together with all other monies received by the Pledgee hereunder, shall be applied in the manner provided in Section 5.4 of the Security Agreement.

(b) It is understood and agreed that each Pledgor shall remain jointly and severally liable with respect to its Obligations to the extent of any deficiency between the amount of the proceeds of the Collateral pledged by it hereunder and the aggregate amount of such Obligations.

(c) It is understood and agreed by each Pledgor and each Secured Creditor that the Pledgee shall have no liability for any determinations made by it in this Section 11, in each case except to the extent resulting from the gross negligence or willful misconduct of the Pledgee (as determined by a court of competent jurisdiction in a final and non-appealable decision). Each Pledgor and each Secured Creditor also agrees that the Pledgee 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 Pledgee shall be entitled to wait for, and may conclusively rely on, any such determination.

12. PURCHASERS OF COLLATERAL. Upon any sale of the Collateral by the Pledgee hereunder (whether by virtue of the power of sale herein granted, pursuant to judicial process or otherwise), the receipt of the Pledgee or the officer making such sale shall be a sufficient discharge to the purchaser or purchasers of the Collateral so sold, and such purchaser or purchasers shall not be obligated to see to the application of any part of the purchase money paid over to the

Page #PageNum#

Pledgee or such officer or be answerable in any way for the misapplication or nonapplication thereof.

13. INDEMNITY. Each Pledgor jointly and severally agrees (i) to indemnify, reimburse and hold harmless the Pledgee and each other Lender Creditor and their respective successors, assigns, employees, agents (including any receiver appointed pursuant to Section 7 hereof) and affiliates (individually an “Indemnitee”, and collectively, the “Indemnitees”) from and against any and all obligations, damages, injuries, penalties, claims, actions, demands, losses, judgments, costs, expenses, disbursements and liabilities (including, without limitation, liabilities for penalties) of whatsoever kind or nature, and (ii) to reimburse each Indemnitee for all reasonable costs, expenses and disbursements, including reasonable attorneys’ fees and expenses (but limited, in the case of attorneys’ fees and expenses, to one counsel to the Pledgee, one additional counsel for all other Lender Creditors, taken as a whole, one local counsel for the Pledgee and the other Lender Creditors, taken as a whole, in each relevant jurisdiction, and, solely in the case of an actual or perceived conflict of interests, one additional counsel in each relevant jurisdiction to each group of affected Indemnitees similarly situated, taken as a whole), in each case arising out of or resulting from this Agreement or the exercise by any Indemnitee of any right or remedy granted to it hereunder or under any other Credit Document (but excluding any obligations, damages, injuries, penalties, claims, actions, demands, losses, judgments, suits, costs, expenses, disbursements and liabilities (including, without limitation, liabilities for penalties) or expenses of whatsoever kind or nature to the extent incurred or arising by reason of gross negligence or willful misconduct of such Indemnitee (as determined by a court of competent jurisdiction in a final and non appealable decision)). In no event shall the Pledgee hereunder be liable, in the absence of gross negligence or willful misconduct on its part (as determined by a court of competent jurisdiction in a final and non appealable decision), for any matter or thing in connection with this Agreement other than to account for monies or other property actually received by it in accordance with the terms hereof. If and to the extent that the obligations of any Pledgor under this Section 13 are unenforceable for any reason, such Pledgor hereby agrees to make the maximum contribution to the payment and satisfaction of such obligations which is permissible under applicable law. The indemnity obligations of each Pledgor contained in this Section 13 shall continue in full force and effect notwithstanding the full payment of all the Notes issued under the Credit Agreement, the termination of all Letters of Credit, and the payment of all other Credit Obligations and notwithstanding the discharge thereof and the occurrence of the Termination Date.

14. PLEDGEE NOT A PARTNER OR LIMITED LIABILITY COMPANY MEMBER. (a) Nothing herein shall be construed to make the Pledgee or any other Secured Creditor liable as a member of any limited liability company or as a partner of any partnership and neither the Pledgee nor any other Secured Creditor by virtue of this Agreement or otherwise (except as referred to in the following sentence) shall have any of the duties, obligations or liabilities of a member of any limited liability company or as a partner in any partnership. The parties hereto expressly agree that, unless the Pledgee shall become the absolute owner of Collateral consisting of a Limited Liability Company Interest or a Partnership Interest pursuant hereto, this Agreement shall not be construed as creating a partnership or joint venture among the Pledgee, any other Secured Creditor, any Pledgor and/or any other Person.

(b) Except as provided in the last sentence of paragraph (a) of this Section 14,

Page #PageNum#

the Pledgee, by accepting this Agreement, did not intend to become a member of any limited liability company or a partner of any partnership or otherwise be deemed to be a co-venturer with respect to any Pledgor, any limited liability company, partnership and/or any other Person either before or after an Event of Default shall have occurred. The Pledgee shall have only those powers set forth herein and the Secured Creditors shall assume none of the duties, obligations or liabilities of a member of any limited liability company or as a partner of any partnership or any Pledgor except as provided in the last sentence of paragraph (a) of this Section 14.

(c) The Pledgee and the other Secured Creditors shall not be obligated to perform or discharge any obligation of any Pledgor as a result of the pledge hereby effected.

(d) The acceptance by the Pledgee of this Agreement, with all the rights, powers, privileges and authority so created, shall not at any time or in any event obligate the Pledgee or any other Secured Creditor to appear in or defend any action or proceeding relating to the Collateral to which it is not a party, or to take any action hereunder or thereunder, or to expend any money or incur any expenses or perform or discharge any obligation, duty or liability under the Collateral.

15. FURTHER ASSURANCES; POWER-OF-ATTORNEY. (a) Each Pledgor agrees that it will, at such Pledgor’s own expense, file and refile, or cause to be filed or refiled, under the UCC or other applicable law such financing statements, continuation statements and other documents, in form reasonably acceptable to the Pledgee, in such offices as the Pledgee (acting on its own or on the instructions of the Required Lenders) may reasonably deem necessary or appropriate and wherever required or permitted by law in order to perfect and preserve the Pledgee’s security interest in the Collateral hereunder and hereby authorizes the Pledgee to file financing statements and amendments thereto relative to all or any part of the Collateral (including, without limitation, financing statements which list the Collateral specifically and/or “all assets” as collateral) without the signature of such Pledgor where permitted by law, in such offices as the Pledgee may reasonably deem necessary or advisable or wherever required or permitted by law in order to perfect and preserve the Pledgee’s security interest in the Collateral hereunder and agrees to do such further acts and things and to execute and deliver to the Pledgee such additional conveyances, assignments, agreements and instruments as the Pledgee may reasonably require or deem advisable to carry into effect the purposes of this Agreement or to further assure and confirm unto the Pledgee its rights, powers and remedies hereunder or thereunder.

(b) Each Pledgor hereby constitutes and appoints the Pledgee its true and lawful attorney-in-fact, irrevocably, with full authority in the place and stead of such Pledgor and in the name of such Pledgor or otherwise, from time to time after the occurrence and during the continuance of an Event of Default, in the Pledgee’s discretion, to act, require, demand, receive and give acquittance for any and all monies and claims for monies due or to become due to such Pledgor under or arising out of the Collateral, to endorse any checks or other instruments or orders in connection therewith and to file any claims or take any action or institute any proceedings and to execute any instrument which the Pledgee may deem necessary or advisable to accomplish the purposes of this Agreement, which appointment as attorney is coupled with an interest.

16. THE PLEDGEE AS COLLATERAL AGENT. The Pledgee will hold in accordance with this Agreement all items of the Collateral at any time received under this Agreement.

It is expressly understood, acknowledged and agreed by each Secured Creditor that by accepting the benefits of this Agreement each such Secured Creditor acknowledges and agrees that the obligations of the Pledgee as holder of the Collateral and interests therein and with respect to the disposition thereof, and otherwise under this Agreement, are only those expressly set forth in this Agreement and in Section 12 of the Credit Agreement. The Pledgee shall act hereunder on the terms and conditions set forth herein and in Section 12 of the Credit Agreement.

17. TRANSFER BY THE PLEDGORS. Except as permitted by the terms of the Credit Documents prior to the Termination Date, no Pledgor will sell or otherwise dispose of, grant any option with respect to, or mortgage, pledge or otherwise encumber any of the Collateral or any interest therein.

18. REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE PLEDGORS. (a) Each Pledgor represents, warrants and covenants as to itself and each of its Subsidiaries that:

21. SALE OF COLLATERAL WITHOUT REGISTRATION. (a) If an Event of Default shall have occurred and be continuing and any Pledgor shall have received from the Pledgee a written request or requests that such Pledgor cause any registration, qualification or compliance under any federal or state securities law or laws to be effected with respect to all or any part of the Collateral consisting of Securities, Limited Liability Company Interests or Partnership Interests, such Pledgor as soon as practicable and at its expense will use its best efforts to cause such registration to be effected (and be kept effective) and will use its best efforts to cause such qualification and compliance to be effected (and be kept effective) as may be so requested and as would permit or facilitate the sale and distribution of such Collateral consisting of Securities, Limited Liability Company Interests or Partnership Interests, including, without limitation, registration under the Securities Act, as then in effect (or any similar statute then in effect), appropriate qualifications under applicable blue sky or other state securities laws and appropriate compliance with any other governmental requirements; provided, that the Pledgee shall furnish to such Pledgor such information regarding the Pledgee as such Pledgor may request in writing and as shall be required in connection with any such registration, qualification or compliance. Each Pledgor will cause the Pledgee to be kept reasonably advised in writing as to the progress of each such registration, qualification or compliance and as to the completion thereof, will furnish to the Pledgee such number of prospectuses, offering circulars and other documents incident thereto as the Pledgee from time to time may reasonably request, and will indemnify, to the extent permitted by law, the Pledgee and all other Secured Creditors participating in the distribution of such Collateral consisting of Securities, Limited Liability Company Interests or Partnership Interests against all claims, losses, damages and liabilities caused by any untrue statement (or alleged untrue statement) of a material fact contained therein (or in any related registration statement, notification or the like) or by any omission (or alleged omission) to state therein (or in any related registration statement, notification or the

Page #PageNum#

(b) If at any time when the Pledgee shall determine to exercise its right to sell all or any part of the Collateral consisting of Securities, Limited Liability Company Interests or Partnership Interests pursuant to Section 7 hereof, and such Collateral or the part thereof to be sold shall not, for any reason whatsoever, be effectively registered under the Securities Act, as then in effect, the Pledgee may, in its sole and absolute discretion, sell such Collateral or part thereof by private sale in such manner and under such circumstances as the Pledgee may deem necessary or advisable in order that such sale may legally be effected without such registration. Without limiting the generality of the foregoing, in any such event the Pledgee, in its sole and absolute discretion (i) may proceed to make such private sale notwithstanding that a registration statement for the purpose of registering such Collateral or part thereof shall have been filed under such Securities Act, (ii) may approach and negotiate with a single possible purchaser to effect such sale, and (iii) may restrict such sale to a purchaser who will represent and agree that such purchaser is purchasing for its own account, for investment, and not with a view to the distribution or sale of such Collateral or part thereof. In the event of any such sale, the Pledgee shall incur no responsibility or liability for selling all or any part of the Collateral at a price which the Pledgee, in its sole and absolute discretion, may in good xxxxx xxxx reasonable under the circumstances, notwithstanding the possibility that a substantially higher price might be realized if the sale were deferred until the registration as aforesaid.

22. TERMINATION; RELEASE.

(b) In the event that any part of the Collateral is sold or otherwise disposed of (to a Person other than a Credit Party) at any time prior to the Termination Date, in connection with a sale or disposition permitted by Section 10.02 of the Credit Agreement, or is otherwise released at the direction of the Required Lenders, and the proceeds of such sale or disposition (or from such release) are applied in accordance with the terms of the Credit Agreement to the extent required to

Page #PageNum#

be so applied, the Pledgee, at the request and expense of such Pledgor, will duly release from the security interest created hereby (and will execute and deliver such documentation, including termination or partial release statements and the like in connection therewith) and assign, transfer and deliver to such Pledgor (without recourse and without any representation or warranty) such of the Collateral as is then being (or has been) so sold or otherwise disposed of, or released, and as may be in the possession of the Pledgee (or, in the case of Collateral held by any sub-agent designated pursuant to Section 4 hereof, such sub‑agent) and has not theretofore been released pursuant to this Agreement. Furthermore, upon the release of any U.S. Guarantor from the U.S. Guaranty in accordance with the provisions thereof, such Pledgor (and the Collateral at such time assigned or pledged by the respective Pledgor pursuant hereto) shall be released from this Agreement. In the case of any such sale or disposition of any property constituting Collateral in a transaction permitted pursuant to Section 10.02 of the Credit Agreement, the Liens created by any of this Agreement on such Collateral shall be automatically released without need for further action by any Person.

(c) At any time that any Pledgor desires that the Pledgee deliver any release or such other documentation as provided in the foregoing Section 22(a) or (b), such Pledgor shall deliver to the Pledgee (and the relevant sub-agent, if any, designated pursuant to Section 4 hereof) a certificate signed by an Authorized Officer of such Pledgor stating that the release of the respective Collateral is permitted pursuant to Section 22(a) or (b) hereof. At any time that the Company or the respective Pledgor desires that a U.S. Guarantor which has been released from the U.S. Guaranty be released hereunder as provided in the penultimate sentence of Section 22(b), it shall deliver to the Pledgee a certificate signed by an Authorized Officer of the Company and the respective Pledgor stating that the release of the respective Pledgor (and its Collateral) is permitted pursuant to such Section 22(b).
