The balance of such Proceeds may, at the sole discretion of the Creditor, be held as collateral security for the Secured Liabilities or be applied to such of the Secured Liabilities (whether or not the same are due and payable) in such manner and at such times as the Creditor considers appropriate and thereafter shall be accounted for as required by Law.

Effective upon the occurrence and during the continuance of an Event of Default, the Pledgor irrevocably constitutes and appoints the Creditor and any officer or agent of the Creditor, with full power of substitution, as the Pledgor’s true and lawful attorney-in-fact with full power and authority in the place of the Pledgor and in the name of the Pledgor or in its own name, from time to time in the Creditor’s discretion, to provide instructions or entitlement orders to the Securities Intermediary, and to delegate its powers and for any delegate to sub-delegate the same, to take any and all appropriate action and to execute any and all documents and instruments as, in the opinion of such attorney, may be necessary or desirable to accomplish the purposes of this Agreement (but the Creditor shall not be obligated to and shall have no liability to the Pledgor or any third party for failure to do so or take any action). Without limiting the effect of this Section, the Pledgor grants the Creditor an irrevocable proxy to vote the Pledged Shares and to exercise all other rights, powers, privileges and remedies to which a holder thereof would be entitled (including giving or withholding written consents of shareholders, calling special meetings of shareholders and voting at such meetings), which proxy shall be effective, automatically and without the necessity of any action (including any transfer of any Pledged Shares on the books and records of a Pledged Issuer), upon the occurrence of an Event of Default. These powers are coupled with an interest and are irrevocable until the Release Date. Nothing in this Section affects the right of the Creditor as secured party or any other Person on the Creditor’s behalf, to sign and file or deliver (as applicable) all such financing statements, financing change statements, notices, verification statements and other documents relating to the Collateral and this Agreement as the Creditor or such other Person considers appropriate. The Pledgor hereby ratifies and confirms, and agrees to ratify and confirm, whatever lawful acts the Creditor or any of the Creditor’s sub-agents, nominees or attorneys do or purport to do in exercise of the power of attorney granted to the Creditor pursuant to this Section.

16. Performance by Creditor of Pledgor’s Obligations. If the Pledgor fails to perform or comply with any of the obligations under this Agreement, the Creditor may, but need not, perform or otherwise cause the performance or compliance of such obligation, provided that such performance or compliance shall not constitute a waiver, remedy or satisfaction of such failure. The expenses of the Creditor incurred in connection with any such performance or compliance shall be payable by the Pledgor to the Creditor immediately on demand, and until paid, any such expenses shall form part of the Secured Liabilities and shall be secured by the Security Interest.

17. Severability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of such prohibition or unenforceability and shall be severed from the balance of this Agreement, all without affecting the remaining provisions of this Agreement or affecting the validity or enforceability of such provision in any other jurisdiction.

18. Rights of Creditor; Limitations on Creditor’s Obligations.

(a) Limitations on Creditor’s Liability. The Creditor shall not be liable to the Pledgor or any other Person for any failure or delay in exercising any of the rights of the Pledgor under this Agreement (including any failure to take possession of, collect, sell, lease or otherwise dispose of any Collateral, or to preserve rights against prior parties). Neither the Creditor nor any agent of the Creditor (including, in Alberta or British Columbia, any sheriff) is required to take, or shall have any liability for any failure to take or delay in taking, any steps necessary or advisable to preserve rights against other Persons under any Collateral in its possession. Neither the Creditor nor any agent of the Creditor shall be liable for any, and the Pledgor shall bear the full risk of all, loss or damage to any and all of the Collateral (including any Collateral in the possession of the Creditor or any agent of the Creditor) caused for any reason other than the gross negligence or wilful misconduct of the Creditor or such agent of the Creditor.

(b) Use of Agents. The Creditor may perform any of its rights or duties under this Agreement by or through agents and is entitled to retain counsel and to act in reliance on the advice of such counsel concerning all matters pertaining to its rights and duties under this Agreement.

19. Dealings by Creditor. The Creditor may grant extensions of time and other indulgences, take and give up security, accept compositions, grant releases and discharges and otherwise deal with the Pledgor and any other Person, and with any or all of the Collateral, and with other security and sureties, as the Creditor may see fit, all without prejudice to the Secured Liabilities or to the rights and remedies of the Creditor under this Agreement. The powers conferred on the Creditor under this Agreement are solely to protect the interests of the Creditor in the Collateral and shall not impose any duty upon the Creditor to exercise any such powers.

20. Communication. Any notice or other communication required or permitted to be given under this Agreement will be made in accordance with the terms of the Limited Recourse Guarantee.

21. Release of Information. The Pledgor authorizes the Creditor to provide a copy of this Agreement and such other information as may be requested of the Creditor (i) to the extent necessary to enforce the Creditor’s rights, remedies and entitlements under this Agreement, (ii) to any assignee or prospective assignee of all or any part of the Secured Liabilities, and (iii) as required by applicable Law.

22. Indemnity. The Pledgor hereby agrees to indemnify and hold harmless the Creditor and each officer, director, employee, contractor and advisor of the Creditor (each such Person being called an "Indemnified Party") from any losses, damages, liabilities, claims and related expenses (including the fees and expenses of legal counsel), incurred by the Indemnified Party or asserted against any Indemnified Party by any Person (including the Pledgor or any other Loan Party) other than such Indemnified Party and its officers, directors, employees, contractors and advisors arising out of, in connection with or resulting from this Agreement (including, without limitation, enforcement of this Agreement) or any failure of any Secured Liabilities to be the legal, valid, and binding obligations of any Loan Party enforceable against such Loan Party in accordance with their terms, whether brought by a third party or by the Pledgor or any other Loan Party, and regardless of whether any Indemnified Party is a party thereto; provided that such indemnity shall not, as to any Indemnified Party, be available to the extent that such losses, claims, damages, liabilities or related expenses (i) are determined by a court of competent jurisdiction by final and non-appealable judgment to have resulted from the gross negligence or wilful misconduct of such Indemnified Party or (ii) result from a claim brought by the Pledgor or any other Loan Party against an Indemnified Party for breach in bad faith of such Indemnified Party's obligations hereunder or under any other Loan Document, if such Pledgor or such Loan Party has obtained a final and non- appealable judgment in its favour on such claim as determined by a court of competent jurisdiction.

23. Release of Pledgor. Upon the written request of the Pledgor given at any time on or after the Release Date, the Creditor shall, at the expense of the Pledgor, release the Pledgor and the Collateral from the Security Interests. Upon such release, and at the request and expense of the Pledgor, the Creditor shall execute and deliver to the Pledgor such releases and discharges as the Pledgor may reasonably request.

24. Additional Security. This Agreement is in addition to, and not in substitution of, any and all other security previously or concurrently delivered by the Pledgor or any other Person to the Creditor, all of which other security shall remain in full force and effect.

25. Alteration or Waiver. None of the terms or provisions of this Agreement may be waived, amended, supplemented or otherwise modified except by a written instrument executed by the Creditor, except with respect to Schedule A hereto which may be supplemented from time to time by the parties hereto. The Creditor shall not, by any act or delay, be deemed to have waived any right or remedy hereunder or to have acquiesced in any Event of Default or in any breach of any of the terms and conditions hereof. No failure to exercise, nor any delay in exercising, on the part of the Creditor, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by the Creditor of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy which the Creditor would otherwise have on any future occasion. Neither the taking of any judgment nor the exercise of any power of seizure or sale shall extinguish the liability of the Pledgor to pay the Secured Liabilities, nor shall the same operate as a merger of any covenant contained in this Agreement or of any other liability, nor shall the acceptance of any payment or other security constitute or create any novation.

26. Amalgamation. If the Pledgor is a corporation, the Pledgor acknowledges that if it amalgamates or merges with any other corporation or corporations, then (i) the Collateral and the Security Interests shall extend to and include all the property and assets of the amalgamated corporation and to any property or assets of the amalgamated corporation thereafter owned or acquired, (ii) the term “Pledgor”, where used in this Agreement, shall extend to and include the amalgamated corporation, and (iii) the term “Secured Liabilities”, where used in this Agreement, shall extend to and include the Secured Liabilities of the amalgamated corporation.

27. Governing Law; Attornment. This Agreement shall be governed by and construed in accordance with the Laws of the Province of Ontario and the federal laws of Canada applicable therein. Without prejudice to the ability of the Creditor to enforce this Agreement in any other proper jurisdiction, the Pledgor irrevocably submits and attorns to the non-exclusive jurisdiction of the courts of such province. To the extent permitted by applicable Law, the Pledgor irrevocably waives any objection (including any claim of inconvenient forum) that it may now or hereafter have to the venue of any legal proceeding arising out of or relating to this Agreement in the courts of such Province.
