Concurrently with such Holder ceasing to be a holder of Exchangeable Shares, the Holder shall be considered and deemed for all purposes to be the holder of the shares of OSI Common Stock delivered to it pursuant to the Exchange Right. Notwithstanding the foregoing, until the Exchangeable Share Consideration is delivered to the Holder, the Holder shall be deemed to still be a holder of the sold Exchangeable Shares for purposes of the Voting Rights with respect thereto. 5.7 EXERCISE OF EXCHANGE RIGHT SUBSEQUENT TO RETRACTION In the event that a Holder has exercised its right under Article 6 of the Exchangeable Share Provisions to require PTI Holdco to redeem any or all of the Exchangeable Shares held by the Holder (the "Retracted Shares") and is notified by PTI Holdco pursuant to Section 6.6 of the Exchangeable Share Provisions that PTI Holdco will not be permitted as a result of liquidity or solvency provisions of applicable law to redeem all such Retracted Shares, subject to receipt by the Trustee of written notice to that effect from PTI Holdco and provided that OSI or OSI ULC shall not have exercised the Retraction Call Right with respect to the Retracted Shares and that the Holder has not revoked the retraction request delivered by the Holder to PTI Holdco pursuant to Section 6.1 of the Exchangeable Share Provisions, the retraction request will constitute and D-13 14 will be deemed to constitute notice from the Holder to the Trustee instructing the Trustee to exercise the Exchange Right with respect to those Retracted Shares which PTI Holdco is unable to redeem. In any such event, PTI Holdco hereby agrees with the Trustee and in favour of the Holder immediately to notify the Trustee of such prohibition against PTI Holdco's redeeming all of the Retracted Shares and immediately to forward or cause to be forwarded to the Trustee all relevant materials delivered by the Holder to PTI Holdco or to the transfer agent of the Exchangeable Shares (including without limitation a copy of the retraction request delivered pursuant to Section 6.1 of the Exchangeable Share Provisions) in connection with such proposed redemption of the Retracted Shares, and the Trustee will thereupon exercise the Exchange Right with respect to the Retracted Shares which PTI Holdco is not permitted to redeem and will require OSI or OSI ULC to purchase such shares in accordance with the provisions of this Article 5. 5.8 STAMP OR OTHER TRANSFER TAXES Upon any sale of Exchangeable Shares to OSI or OSI ULC pursuant to the Exchange Right or the Automatic Exchange Rights, the share certificate or certificates representing OSI Common Stock to be delivered in connection with the payment of the total purchase price therefor shall be issued in the name of the Holder of the Exchangeable Shares so sold or in such names as such Holder may otherwise direct in writing without charge to the holder of the Exchangeable Shares so sold, provided, however, that such Holder: (a) shall pay (and none of OSI, OSI ULC, PTI Holdco or the Trustee shall be required to pay) any documentary, stamp, transfer or other similar taxes that may be payable in respect of any transfer involved in the issuance or delivery of such shares to a person other than such Holder; or (b) shall have established to the satisfaction of the Trustee, OSI, OSI ULC and PTI Holdco that such taxes, if any, have been paid. PTI Holdco and the Trustee (as directed in writing by PTI Holdco) shall be entitled to deduct and withhold from any consideration otherwise payable under this Agreement to any Holder such amounts as PTI Holdco or the Trustee is required or permitted to deduct and withhold with respect to such payment under the Income Tax Act (Canada), the United States Internal Revenue Code of 1986 or any provision of provincial, state, local or foreign tax law, in each case as amended or succeeded unless such Holder provides to PTI Holdco certificates or such other assurances as are provided for under the Income Tax Act (Canada), the United States Internal Revenue Code of 1986 or such other applicable taxation provisions. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes as having been paid to the Holder in respect of which such deduction and withholding was made, provided that such withheld amounts are actually remitted to the appropriate taxing authority as and when required. To the extent that the amount so required or permitted to be deducted or withheld from any payment to a Holder exceeds the cash portion, if any, of the consideration otherwise payable to the Holder, PTI Holdco and the Trustee are hereby authorized to sell or otherwise dispose of such portion of the consideration as is necessary to provide sufficient funds to PTI Holdco or the Trustee, as the case may be, to enable it to comply with such deduction or withholding requirement and PTI Holdco or the Trustee shall notify the Holder and remit to such Holder any unapplied balance of the net proceeds of such sale. D-14 15 5.9 NOTICE OF INSOLVENCY EVENT Immediately upon the occurrence of an Insolvency Event or any event which with the giving of notice or the passage of time or both would be an Insolvency Event, PTI Holdco and OSI shall give written notice thereof to the Trustee. As soon as practicable after receiving notice from PTI Holdco or OSI of the occurrence of an Insolvency Event, the Trustee will mail to each Holder, at the expense of OSI, a notice of such Insolvency Event in the form provided by OSI, which notice shall contain a brief statement of the right of the Holders with respect to the Exchange Right. 5.10 QUALIFICATION OF OSI COMMON STOCK OSI covenants with the Trustee for the benefit of Holders that if any shares of OSI Common Stock (or other shares or securities into which OSI Common Stock may be reclassified or changed as contemplated by Section 2.7 of the Support Agreement) to be issued and delivered pursuant to the Exchange Right or the Automatic Exchange Rights require registration or qualification with or approval of or the filing of any document including any prospectus or similar document, the taking of any proceeding with or the obtaining of any order, ruling or consent from any governmental or regulatory authority under any Canadian or United States federal, provincial or state law or regulation or pursuant to the rules and regulations of any regulatory authority, or the fulfillment of any other legal requirement (collectively, the "Applicable Laws") before such shares (or other shares or securities into which OSI Common Stock may be reclassified or changed as contemplated by Section 2.7 of the Support Agreement) may be issued and delivered by OSI to the initial holder thereof (other than PTI Holdco) or in order that such shares may be freely tradeable thereafter (other than any restrictions on transfer by reason of a holder being a "control person" of OSI for purposes of Canadian provincial securities law or an "affiliate" of OSI for purposes of United States federal or state securities law and provided such trade is conducted through facilities of a stock exchange outside Canada), OSI will in good faith expeditiously take all such actions and do all such things as are necessary and permitted by Applicable Laws to cause such shares of OSI Common Stock (or other shares or securities into which OSI Common Stock may be reclassified or changed as contemplated by Section 2.7 of the Support Agreement) to be and remain duly registered, qualified or approved at all times in order that such shares may be issued and delivered by OSI to the initial holder thereof (other than PTI Holdco) and in order that such shares or securities may be freely tradeable thereafter (other than any restrictions on transfer by reason of a holder being a "control person" of OSI for purposes of Canadian provincial securities law or an "affiliate" of OSI for purposes of United States federal or state securities law and provided such trade is conducted through facilities of a stock exchange outside Canada) including, without limitation, the filing and maintenance of a registration statement under the Securities Act of 1933. OSI will in good faith expeditiously take all such actions and do all such things as are necessary to cause all shares of OSI Common Stock (or other shares or securities into which OSI Common Stock may be reclassified or changed as contemplated by Section 2.7 of the Support Agreement) to be delivered pursuant to the Exchange Right or the Automatic Exchange Rights to be listed, quoted or posted for trading on all stock exchanges and quotation systems on which such shares are listed, quoted or posted for trading at such time immediately upon their issuance. D-15 16 5.11 RESERVATION OF SHARES OF OSI COMMON STOCK OSI hereby represents, warrants and covenants with the Trustee for the benefit of the Holders that it has irrevocably reserved for issuance and will at all times keep available, free from pre-emptive and other rights, out of its authorized and unissued capital stock such number of shares of OSI Common Stock: (a) as is equal to the sum of (i) the number of Exchangeable Shares issued and outstanding from time to time, and (ii) the number of PTI Stock Options outstanding on the date hereof; and (b) as are now and may hereafter be required to enable and permit PTI Holdco to meet its obligations hereunder, under the Certificate of Incorporation of PTI Holdco, under the Support Agreement, under the Exchangeable Share Provisions and under any other security or commitment pursuant to the Arrangement with respect to which OSI may now or hereafter be required to issue shares of OSI Common Stock. 5.12 AUTOMATIC EXCHANGE ON LIQUIDATION OF OSI (a) OSI will give the Trustee written notice of each of the following events at the time set forth below: (i) in the event of any determination by the board of directors of OSI to institute voluntary liquidation, dissolution or winding-up proceedings with respect to OSI or to effect any other distribution of assets of OSI among its stockholders for the purpose of winding-up its affairs, at least 60 days prior to the proposed effective date of such liquidation, dissolution, winding-up or other distribution; and (ii) immediately, upon the earlier of (A) receipt by OSI of notice of, and (B) OSI otherwise becoming aware of any threatened or instituted claim, suit, petition or other proceedings with respect to the involuntary liquidation, dissolution or winding-up of OSI or to effect any other distribution of assets of OSI among its stockholders for the purpose of winding up its affairs. (b) Immediately following receipt by the Trustee from OSI of notice of any event (a "Liquidation Event") contemplated by Section 5.12(a) above, the Trustee will give notice thereof to the Holders. Such notice will be provided by OSI to the Trustee and shall include a brief description of the automatic exchange of D-16 17 Exchangeable Shares for shares of OSI Common Stock provided for in Section 5.12(c) below. (c) In order that the Holders will be able to participate on a pro rata basis with the holders of OSI Common Stock in the distribution of assets of OSI in connection with a Liquidation Event, immediately prior to the effective time (the "Liquidation Event Effective Time") of a Liquidation Event, all of the then outstanding Exchangeable Shares shall be automatically exchanged for shares of OSI Common Stock. To effect such automatic exchange, OSI shall be deemed to have purchased each Exchangeable Share outstanding immediately prior to the Liquidation Event Effective Time and held by Holders, and each Holder shall be deemed to have sold the Exchangeable Shares held by it at such time, for a purchase price per share equal to the Exchangeable Share Price applicable at such time. In connection with such automatic exchange, OSI will provide to the Trustee an Officer's Certificate setting forth the calculation of the Exchangeable Share Price for each Exchangeable Share. (d) The closing of the transaction of purchase and sale contemplated by Section 5.12(c) above shall be deemed to have occurred immediately prior to the Liquidation Event Effective Time, and each Holder of Exchangeable Shares shall be deemed to have transferred to OSI all of the Holder's right, title and interest in and to such Exchangeable Shares and the related interest in the Trust Estate and shall cease to be a holder of such Exchangeable Shares, and OSI shall deliver to the Holder the Exchangeable Share Consideration deliverable upon the automatic exchange of Exchangeable Shares. Concurrently with such Holder's ceasing to be a holder of Exchangeable Shares, the Holder shall be considered and deemed for all purposes to be the holder of the shares of OSI Common Stock issued to it pursuant to the automatic exchange of Exchangeable Shares for OSI Common Stock, and the certificates held by the Holder previously representing the Exchangeable Shares exchanged by the Holder with OSI pursuant to such automatic exchange shall thereafter be deemed to represent the shares of OSI Common Stock issued to the Holder by OSI pursuant to such automatic exchange. Upon the request of a Holder and the surrender by the Holder of Exchangeable Share certificates deemed to represent shares of OSI Common Stock, duly endorsed in blank and accompanied by such instruments of transfer as OSI may reasonably require, OSI shall deliver or cause to be delivered to the Holder certificates representing the shares of OSI Common Stock of which the Holder is the holder. Notwithstanding the foregoing, until each Holder is actually entered on the register of holders of OSI Common Stock, such Holder shall be deemed to still be a holder of the transferred Exchangeable Shares for purposes of all Voting Rights with respect thereto. ARTICLE 6 RESTRICTIONS ON ISSUANCE OF OSI SPECIAL VOTING STOCK During the term of this agreement, OSI will not issue any shares of OSI Special Voting Stock in addition to the Voting Share. D-17 18 ARTICLE 7 CONCERNING THE TRUSTEE 7.1 POWERS AND DUTIES OF THE TRUSTEE The rights, powers and authorities of the Trustee under this agreement, in its capacity as trustee of the Trust, shall include: (a) receipt and deposit of the Voting Share from OSI as trustee for and on behalf of the Holders in accordance with the provisions of this agreement; (b) granting proxies and distributing materials to Holders as provided in this agreement; (c) voting the Holder Votes in accordance with the provisions of this agreement; (d) receiving the grant of the Exchange Right and the Automatic Exchange Rights from OSI as trustee for and on behalf of the Holders in accordance with the provisions of this agreement; (e) exercising the Exchange Right and enforcing the benefit of the Automatic Exchange Rights, in each case in accordance with the provisions of this agreement, and in connection therewith receiving from Holders Exchangeable Shares and other requisite documents and distributing to such Holders the shares of OSI Common Stock and cheques and property, if any, to which such Holders are entitled upon the exercise of the Exchange Right or pursuant to the Automatic Exchange Rights, as the case may be; (f) holding title to the Trust Estate; (g) investing any moneys forming, from time to time, a part of the Trust Estate as provided in this agreement; (h) taking action at the direction of a Holder or Holders to enforce the obligations of OSI under this agreement; and (i) taking such other actions and doing such other things as are specifically provided in this agreement. In the exercise of such rights, powers and authorities, the Trustee shall have (and is granted) such incidental and additional rights, powers and authority not in conflict with any of the provisions of this agreement as the Trustee, acting in good faith and in the reasonable exercise of its discretion, may deem necessary, appropriate or desirable to effect the purpose of the Trust. Any exercise of such discretionary rights, powers and authorities by the Trustee shall be final, conclusive and binding upon all persons. For greater certainty, the Trustee shall have only those duties as are set out specifically in this agreement. The Trustee in exercising its rights, powers, duties and authorities hereunder shall act honestly and in good faith with a view to the best interests of the Holders and shall exercise the care, diligence and skill that a reasonably prudent trustee would exercise in comparable circumstances. The Trustee shall not be bound to D-18 19 give any notice or do or take any act, action or proceeding by virtue of the powers conferred on it hereby unless and until it shall be specifically required to do so under the terms hereof nor shall the Trustee be required to take any notice of, or to do or to take any act, action or proceeding as a result of any default or breach of any provision hereunder, unless and until notified in writing of such default or breach, which notices shall distinctly specify the default or breach desired to be brought to the attention of the Trustee and in the absence of such notice the Trustee may for all purposes of this agreement conclusively assume that no default or breach has been made in the observance or performance of any of the representations, warranties, covenants, agreements or conditions contained herein. 7.2 NO CONFLICT OF INTEREST The Trustee represents to PTI Holdco and OSI that at the date of execution and delivery of this agreement there exists no material conflict of interest in the role of the Trustee as a fiduciary hereunder and the role of the Trustee in any other capacity. The Trustee shall, within 90 days after it becomes aware that such a material conflict of interest exists, either eliminate such material conflict of interest or resign in the manner and with the effect specified in Article 10 hereof. If, notwithstanding the foregoing provisions of this Section 7.2, the Trustee has such a material conflict of interest, the validity and enforceability of this agreement shall not be affected in any manner whatsoever by reason only of the existence of such material conflict of interest. If the Trustee contravenes the foregoing provisions of this Section 7.2, any interested party may apply to the superior court of the province in which PTI Holdco has its registered office for an order that the Trustee be replaced as trustee hereunder. 7.3 DEALINGS WITH TRANSFER AGENTS, REGISTRARS, ETC. PTI Holdco and OSI irrevocably authorize the Trustee, from time to time, to: (a) consult, communicate and otherwise deal with the respective registrars and transfer agents, and with any such subsequent registrar or transfer agent, of the Exchangeable Shares and OSI Common Stock; and (b) requisition, from time to time, (i) from any such registrar or transfer agent any information readily available from the records maintained by it which the Trustee may reasonably require for the discharge of its duties and responsibilities under this agreement, and (ii) from the transfer agent of OSI Common Stock, and any subsequent transfer agent of such shares, to complete the exercise from time to time of the Exchange Right and the Automatic Exchange Rights in the manner specified in Article 5 hereof, the share certificates issuable upon such exercise. PTI Holdco and OSI irrevocably authorize their respective registrars and transfer agents to comply with all such requests. OSI covenants that it will supply its transfer agent with duly D-19 20 executed share certificates for the purpose of completing the exercise from time to time of the Exchange Right and the Automatic Exchange Rights, in each case pursuant to Article 5 hereof. 7.4 BOOKS AND RECORDS The Trustee shall keep available for inspection by OSI and PTI Holdco, at the Trustee's principal transfer office in Calgary, Alberta, correct and complete books and records of account relating to the Trustee's actions under this agreement, including without limitation all information relating to mailings and instructions to and from Holders and all transactions pursuant to the Voting Rights, the Exchange Right and the Automatic Exchange Rights for the term of this agreement. On or before March 31, 2001, and on or before March 31 in every year thereafter, so long as the Voting Share is on deposit with the Trustee, the Trustee shall transmit to OSI and PTI Holdco a brief report, dated as of the preceding December 31, with respect to: (a) the property and funds comprising the Trust Estate as of that date; (b) the number of exercises of the Exchange Right, if any, and the aggregate number of Exchangeable Shares received by the Trustee on behalf of Holders in consideration of the issue and delivery by OSI of shares of OSI Common Stock in connection with the Exchange Right, during the calendar year ended on such date; and (c) all other actions taken by the Trustee in the performance of its duties under this agreement which it had not previously reported. 7.5 INCOME TAX RETURNS AND REPORTS The Trustee shall, to the extent necessary, prepare and file on behalf of the Trust appropriate United States and Canadian income tax returns and any other returns or reports as may be required by applicable law or pursuant to the rules and regulations of any securities exchange or other trading system through which the Exchangeable Shares are traded and, in connection therewith, may obtain the advice and assistance of such experts as the Trustee may consider necessary or advisable. If requested by the Trustee, OSI shall retain such experts for purposes of providing such advice and assistance. 7.6 INDEMNIFICATION PRIOR TO CERTAIN ACTIONS BY TRUSTEE The Trustee shall exercise any or all of the rights, duties, powers or authorities vested in it by this agreement at the request, order or direction of any Holder upon such Holder's furnishing to the Trustee reasonable funding, security and indemnity against the costs, expenses and liabilities which may be incurred by the Trustee therein or thereby; provided that no Holder shall be obligated to furnish to the Trustee any such funding, security or indemnity in connection with the exercise by the Trustee of any of its rights, duties, powers and authorities with respect to the Voting Share pursuant to Article 4 hereof, subject to Section 7.15 hereof, and with respect to the Exchange Right pursuant to Article 5 hereof, subject to Section 7.15 hereof, and with respect to the Automatic Exchange Rights pursuant to Article 5 hereof. None of the provisions contained in this agreement shall require the Trustee to expend or risk its own funds or otherwise incur D-20 21 financial liability in the exercise of any of its rights, powers, duties or authorities unless funded, given funds, security and indemnified as aforesaid. 7.7 ACTIONS BY HOLDERS No Holder shall have the right to institute any action, suit or proceeding or to exercise any other remedy authorized by this agreement for the purpose of enforcing any of its rights or for the execution of any trust or power hereunder unless the Holder has requested the Trustee to take or institute such action, suit or proceeding and furnished the Trustee with the funding, security and indemnity referred to in Section 7.6 hereof and the Trustee shall have failed to act within a reasonable time thereafter. In such case, but not otherwise, the Holder shall be entitled to take proceedings in any court of competent jurisdiction such as the Trustee might have taken; it being understood and intended that no one or more Holders shall have any right in any manner whatsoever to affect, disturb or prejudice the rights hereby created by any such action, or to enforce any right hereunder or under the Voting Rights, the Exchange Right or the Automatic Exchange Rights, except subject to the conditions and in the manner herein provided, and that all powers and trusts hereunder shall be exercised and all proceedings at law shall be instituted, had and maintained by the Trustee, except only as herein provided, and in any event for the equal benefit of all Holders. 7.8 RELIANCE UPON DECLARATIONS The Trustee shall not be considered to be in contravention of any of its rights, powers, duties and authorities hereunder if, when required, it acts and relies in good faith upon lists, mailing labels, notices, statutory declarations, certificates, opinions, reports or other papers or documents furnished pursuant to the provisions hereof or required by the Trustee to be furnished to it in the exercise of its rights, powers, duties and authorities hereunder, and such lists, mailing labels, notices, statutory declarations, certificates, opinions, reports or other papers or documents comply with the provisions of Section 7.9 hereof, if applicable, and with any other applicable provisions of this agreement. 7.9 EVIDENCE AND AUTHORITY TO TRUSTEE PTI Holdco and/or OSI shall furnish to the Trustee evidence of compliance with the conditions provided for in this agreement relating to any action or step required or permitted to be taken by PTI Holdco and/or OSI or the Trustee under this agreement or as a result of any obligation imposed under this agreement, including, without limitation, in respect of the Voting Rights or the Exchange Right or the Automatic Exchange Rights and the taking of any other action to be taken by the Trustee at the request of or on the application of PTI Holdco and/or OSI forthwith if and when: (a) such evidence is required by any other section of this agreement to be furnished to the Trustee in accordance with the terms of this Section 7.9; or (b) the Trustee, in the exercise of its rights, powers, duties and authorities under this agreement, gives PTI Holdco and/or OSI written notice requiring it to furnish such evidence in relation to any particular action or obligation specified in such notice. D-21 22 Such evidence shall consist of an Officer's Certificate of PTI Holdco and/or OSI or a statutory declaration or a certificate made by persons entitled to sign an Officer's Certificate stating that any such condition has been complied with in accordance with the terms of this agreement. Whenever such evidence relates to a matter other than the Voting Rights or the Exchange Right or the Automatic Exchange Rights, and except as otherwise specifically provided herein, such evidence may consist of a report or opinion of any solicitor, auditor, accountant, appraiser, valuer, engineer or other expert or any other person whose qualifications give authority to a statement made by him, provided that, if such report or opinion is furnished by a director, officer or employee of PTI Holdco and/or OSI, it shall be in the form of an Officer's Certificate or a statutory declaration. Each statutory declaration, certificate, opinion or report furnished to the Trustee as evidence of compliance with a condition provided for in this agreement shall include a statement by the person giving the evidence: (i) declaring that such person has read and understands the provisions of this agreement relating to the condition in question; (ii) describing the nature and scope of the examination or investigation upon which such person based the statutory declaration, certificate, statement or opinion; and (iii) declaring that such person has made such examination or investigation as such person believes is necessary to enable such person to make the statements or give the opinions contained or expressed therein. 7.10 EXPERTS, ADVISERS AND AGENTS The Trustee may: (a) in relation to these presents act and rely on the opinion or advice of or information obtained from or prepared by any solicitor, auditor, accountant, appraiser, valuer, engineer or other expert, whether retained by the Trustee or by PTI Holdco and/or OSI or otherwise, and may employ such assistants as may be necessary to the proper determination and discharge of its powers and duties and determination of its rights hereunder and may pay proper and reasonable compensation for all such legal and other advice or assistance as aforesaid; and (b) employ such agents and other assistants as it may reasonably require for the proper determination and discharge of its powers and duties hereunder, and may pay reasonable remuneration for all services performed for it (and shall be entitled to receive reasonable remuneration for all services performed by it) in the discharge of the trusts hereof and compensation for all disbursements, costs and expenses made or incurred by it in the determination and discharge of its duties hereunder and in the management of the Trust. D-22 23 7.11 INVESTMENT OF MONEYS HELD BY TRUSTEE Unless otherwise provided in this agreement, any moneys held by or on behalf of the Trustee which under the terms of this agreement may or ought to be invested or which may be on deposit with the Trustee or which may be in the hands of the Trustee, may be invested and reinvested in the name or under the control of the Trustee in securities in which, under the laws of the Province of Alberta, trustees are authorized to invest trust moneys; provided that such securities are stated to mature within two years after their purchase by the Trustee, and the Trustee shall so invest such moneys on the written direction of PTI Holdco. Pending the investment of any moneys as hereinbefore provided, such moneys may be deposited in the name of the Trustee in any chartered bank in Canada or, with the consent of PTI Holdco, in the deposit department of the Trustee or any other loan or trust company authorized to accept deposits under the laws of Canada or any province thereof at the rate of interest then current on similar deposits. 7.12 TRUSTEE NOT REQUIRED TO GIVE SECURITY The Trustee shall not be required to give any bond or security in respect of the execution of the trusts, rights, duties, powers and authorities of this agreement or otherwise in respect of the premises. 7.13 TRUSTEE NOT BOUND TO ACT ON REQUEST Except as in this agreement otherwise specifically provided, the Trustee shall not be bound to act in accordance with any direction or request of PTI Holdco and/or OSI or of the directors thereof until a duly authenticated copy of the instrument or resolution containing such direction or request shall have been delivered to the Trustee, and the Trustee shall be empowered to act and rely upon any such copy purporting to be authenticated and believed by the Trustee to be genuine. 7.14 AUTHORITY TO CARRY ON BUSINESS The Trustee represents to PTI Holdco and OSI that at the date of execution and delivery by it of this agreement it is authorized to carry on the business of a trust company in the Province of Alberta but if, notwithstanding the provisions of this Section 7.14, it ceases to be so authorized to carry on business, the validity and enforceability of this agreement and the Voting Rights, the Exchange Right and the Automatic Exchange Rights shall not be affected in any manner whatsoever by reason only of such event; provided, however, the Trustee shall, within 90 days after ceasing to be authorized to carry on the business of a trust company in the Province of Alberta, either become so authorized or resign in the manner and with the effect specified in Article 10 hereof. 7.15 CONFLICTING CLAIMS If conflicting claims or demands are made or asserted with respect to any interest of any Holder in any Exchangeable Shares, including any disagreement between the heirs, representatives, successors or assigns succeeding to all or any part of the interest of any Holder in any Exchangeable Shares resulting in conflicting claims or demands being made in connection with such interest, then the Trustee shall be entitled, at its sole discretion, to refuse to recognize D-23 24 or to comply with any such claim or demand. In so refusing, the Trustee may elect not to exercise any Voting Rights, Exchange Right or Automatic Exchange Rights subject to such conflicting claims or demands and, in so doing, the Trustee shall not be or become liable to any person on account of such election or its failure or refusal to comply with any such conflicting claims or demands. The Trustee shall be entitled to continue to refrain from acting and to refuse to act until: (a) the rights of all adverse claimants with respect to the Voting Rights, Exchange Right or Automatic Exchange Rights subject to such conflicting claims or demands have been adjudicated by a final judgment of a court of competent jurisdiction; or (b) all differences with respect to the Voting Rights, Exchange Right or Automatic Exchange Rights subject to such conflicting claims or demands have been conclusively settled by a valid written agreement binding on all such adverse claimants, and the Trustee shall have been furnished with an executed copy of such agreement. If the Trustee elects to recognize any claim or comply with any demand made by any such adverse claimant, it may in its discretion require such claimant to furnish such surety bond or other security satisfactory to the Trustee as it shall deem appropriate fully to indemnify it as between all conflicting claims or demands. 7.16 ACCEPTANCE OF TRUST The Trustee hereby accepts the Trust created and provided for by and in this agreement and agrees to perform the same upon the terms and conditions herein set forth and to hold all rights, privileges and benefits conferred hereby and by law in trust for the various persons who shall from time to time be Holders, subject to all the terms and conditions herein set forth. ARTICLE 8 COMPENSATION OSI and PTI Holdco jointly and severally agree to pay to the Trustee reasonable compensation for all of the services rendered by it under this agreement and will reimburse the Trustee for all reasonable expenses (including but not limited to taxes, compensation paid to experts, agents and advisors, and travel expenses) and disbursements, including the cost and expense of any suit or litigation of any character and any proceedings before any governmental agency, reasonably incurred by the Trustee in connection with its rights and duties under this agreement; provided that OSI and PTI Holdco shall have no obligation to reimburse the Trustee for any expenses or disbursements paid, incurred or suffered by the Trustee in any suit or litigation in which the Trustee is determined to have acted in bad faith or with negligence or willful misconduct. D-24 25 ARTICLE 9 INDEMNIFICATION AND LIMITATION OF LIABILITY 9.1 INDEMNIFICATION OF THE TRUSTEE OSI and PTI Holdco jointly and severally agree to indemnify and hold harmless the Trustee and each of its directors, officers, employees and agents appointed and acting in accordance with this agreement (collectively, the "Indemnified Parties") against all claims, losses, damages, costs, penalties, fines and reasonable expenses (including reasonable expenses of the Trustee's legal counsel) which, without fraud, negligence, willful misconduct or bad faith on the part of such Indemnified Party, may be paid, incurred or suffered by the Indemnified Party by reason of or as a result of the Trustee's acceptance or administration of the Trust, its compliance with its duties set forth in this agreement, or any written or oral instructions delivered to the Trustee by OSI or PTI Holdco pursuant hereto. In no case shall OSI or PTI Holdco be liable under this indemnity for any claim against any of the Indemnified Parties unless OSI and PTI Holdco shall be notified by the Trustee of the written assertion of a claim or of any action commenced against the Indemnified Parties, promptly after any of the Indemnified Parties shall have received any such written assertion of a claim or shall have been served with a summons or other first legal process giving information as to the nature and basis of the claim. Subject to (ii) below, OSI and PTI Holdco shall be entitled to participate at their own expense in the defense and, if OSI or PTI Holdco so elect at any time after receipt of such notice, either of them may assume the defense of any suit brought to enforce any such claim. The Trustee shall have the right to employ separate counsel in any such suit and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of the Trustee unless: (i) the employment of such counsel has been authorized by OSI or PTI Holdco, such authorization not to be unreasonably withheld; or (ii) the named parties to any such suit include both the Trustee and OSI or PTI Holdco and the Trustee shall have been advised by counsel acceptable to OSI or PTI Holdco that there may be one or more legal defenses available to the Trustee that are different from or in addition to those available to OSI or PTI Holdco and that an actual or potential conflict of interest exists (in which case OSI and PTI Holdco shall not have the right to assume the defense of such suit on behalf of the Trustee, but shall be liable to pay the reasonable fees and expenses of counsel for the Trustee). This indemnity shall survive the resignation or removal of the Trustee and the termination of the trust. 9.2 LIMITATION OF LIABILITY The Trustee shall not be held liable for any loss which may occur by reason of depreciation of the value of any part of the Trust Estate or any loss incurred on any investment of funds pursuant to this agreement, except to the extent that such loss is attributable to the fraud, negligence, willful misconduct or bad faith on the part of the Trustee. ARTICLE 10 CHANGE OF TRUSTEE 10.1 RESIGNATION The Trustee, or any trustee hereafter appointed, may at any time resign by giving written notice of such resignation to OSI and PTI Holdco specifying the date on which it desires to D-25 26 resign, provided that such notice shall never be given less than 60 days before such desired resignation date unless OSI and PTI Holdco otherwise agree and provided further that such resignation shall not take effect until the date of the appointment of a successor trustee and the acceptance of such appointment by the successor trustee. Upon receiving such notice of resignation, OSI and PTI Holdco shall promptly appoint a successor trustee by written instrument, in duplicate, one copy of which shall be delivered to the resigning trustee and one copy to the successor trustee. Failing acceptance by a successor trustee, a successor trustee may be appointed by an order of the superior court of the province in which PTI Holdco has its registered office upon application of one or more of the parties hereto. 10.2 REMOVAL The Trustee, or any trustee hereafter appointed, may be removed with or without cause, at any time on 60 days prior notice by written instrument executed by OSI and PTI Holdco, in duplicate, one copy of which shall be delivered to the trustee so removed and one copy to the successor trustee; provided that, in connection with such removal, provision is made for a replacement trustee similar to that contemplated in Section 10.1. 10.3 SUCCESSOR TRUSTEE Any successor trustee appointed as provided under this agreement shall execute, acknowledge and deliver to OSI and PTI Holdco and to its predecessor trustee an instrument accepting such appointment. Thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor under this agreement, with like effect as if originally named as trustee in this agreement. However, on the written request of OSI and PTI Holdco or of the successor trustee, the trustee ceasing to act shall, upon payment of any amounts then due it pursuant to the provisions of this agreement, execute and deliver an instrument transferring to such successor trustee all the rights and powers of the trustee so ceasing to act. Upon the request of any such successor trustee, OSI, PTI Holdco and such predecessor trustee shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor trustee all such rights and powers. 10.4 NOTICE OF SUCCESSOR TRUSTEE Upon acceptance of appointment by a successor trustee as provided herein, OSI and PTI Holdco shall cause to be mailed notice of the succession of such trustee hereunder to each Holder specified in a List.
