(ii) Any such shares so included in the OSI Initial Public Offering would be allocated for sale by the Eligible Secondary Stockholders pro rata in accordance with their pro forma share ownership in OSI taking into account the consummation of the Mergers; provided, however, that any shares not included in the OSI Initial Public Offering at the election of any of the Eligible Secondary Stockholders shall be made available for inclusion in the OSI Initial Public Offering, pro rata as provided above, to the other Eligible Secondary Stockholders who have fully exercised their right to participate. (iii) If the Eligible Secondary Stockholders may be entitled to include OSI Common Stock in the OSI Initial Public Offering, OSI shall give written notice to each of the Eligible Secondary Stockholders, at the address indicated in the records of HWC, Sooner, PTI, or OSI, as applicable, and each Eligible Secondary Stockholder must notify OSI in writing within 15 days of the giving of such notice if such Eligible Secondary Stockholder desires to so include shares and the maximum number of shares of OSI Common Stock to be included. No Eligible Secondary Stockholder may participate in the OSI Initial Public Offering unless such Eligible Secondary Stockholder timely completes, executes and delivers all questionnaires, powers of attorney, underwriting agreements, custody agreements and other documents in customary form that OSI or the underwriters reasonably request. Any Eligible Secondary Stockholder shall be permitted to withdraw all or part of such Eligible Secondary Stockholder's OSI Common Stock from the OSI Registration Statement at any time prior to the effective time thereof unless OSI has previously given written notice to the 36 38 Eligible Secondary Stockholders of the initial public offering price range included, or to be included (provided that such range is the range ultimately included), in the "red herring" and indicated that the Eligible Secondary Stockholders may not withdraw their OSI Common Stock after five days after the giving of such notice if the initial public offering price of OSI Common Stock in the OSI Initial Public Offering equals or exceeds the lowest price in such initial public offering price range, in which case the Eligible Secondary Stockholder may not withdraw OSI Common Stock from the OSI Registration Statement after such fifth day unless the initial public offering price is below such lowest price. (iv) OSI shall not, and shall not be entitled to, issue and sell OSI Common Stock in the OSI Initial Public Offering for aggregate proceeds in excess of $150,000,000, including any proceeds received upon the exercise of any over-allotment option granted to the underwriters of the OSI Initial Public Offering in connection therewith, unless the Eligible Secondary Stockholders have first been given the right and opportunity to sell OSI Common Stock in the OSI Initial Public Offering having aggregate gross proceeds of at least $25,000,000, except as set forth in subparagraph (v) below. (v) Counsel to OSI, in consultation with counsel to the Eligible Secondary Stockholder of the greatest number of shares of OSI Common Stock (the "Largest Eligible Secondary Stockholder"), may determine that shares of OSI Common Stock to be held as a result of the transactions contemplated in this Combination Agreement are not eligible for inclusion in the OSI Registration Statement because of applicable law. In the event that it is determined that no shares of OSI Common Stock held by the Eligible Secondary Stockholders are eligible for inclusion in the OSI Initial Public Offering or that the number of shares of OSI Common Stock held by the Eligible Secondary Stockholders eligible for inclusion in the OSI Initial Public Offering is such that the aggregate gross proceeds to the Eligible Secondary Stockholders shall be less than $25,000,000, the reference to "$25,000,000" in subparagraph (iv) above shall be read as a reference to the maximum aggregate gross proceeds, if any, to the Eligible Secondary Stockholders as so determined. (vi) The underwriters and the public offering price and, subject to the foregoing provisions of this Section 11.9(d), the number of shares and any over-allotment option will be determined by the Board of Directors of OSI in its sole discretion; provided, however, that: (A) OSI shall, and shall require the underwriters to, consult with the Largest Eligible Secondary Stockholder expeditiously and in good faith prior to determining (1) that the gross proceeds of the OSI Initial Public Offering (including any proceeds to OSI upon the exercise of any over-allotment option granted in connection therewith) are not expected to be greater than $150,000,000 and, accordingly, that no shares of OSI Common Stock held by the Eligible Secondary Stockholders are to be included in the OSI Initial Public Offering or (2) that the gross proceeds of the OSI Initial Public Offering (including any proceeds upon the exercise of any over-allotment option granted in connection therewith) are expected to be greater than $150,000,000 but less than $175,000,000 and, accordingly, that the 37 39 number of shares of OSI Common Stock held by the Eligible Secondary Stockholders to be included in the OSI Initial Public Offering shall be such that the aggregate gross proceeds to the Eligible Secondary Stockholders shall be less than $25,000,000 and (B) the Largest Eligible Selling Stockholder shall be entitled to be present at the time that the public offering price, the number of shares and the over-allotment option are determined by OSI and the underwriters, it being acknowledged with respect to each of clauses (A) and (B) above that such determination shall ultimately be made by the board of directors of OSI and the underwriters acting in good faith and shall not require the consent or approval of the Eligible Secondary Stockholders or any of them and it being further acknowledged that the board of directors of OSI shall be entitled to reduce the size of the OSI Initial Public Offering (and thereby reduce or eliminate the shares of OSI Common Stock otherwise eligible to be sold by the Eligible Secondary Stockholders) if it believes in good faith that such action will increase the initial public offering price per share of the OSI Common Stock in the OSI Initial Public Offering. (vii) Subject to the foregoing provisions of this Section 11.9(d), OSI is under no obligation to include any shares of OSI Common Stock held by the Eligible Secondary Stockholders in the OSI Registration Statement. (viii) If any shares of OSI Common Stock owned by the stockholders of OSI or to be owned by the stockholders of HWC, Sooner or PTI are included in the OSI Registration Statement, the stockholders of OSI and the former stockholders of HWC, Sooner and PTI, as the case may be, shall be required to provide, and shall be entitled to receive, indemnification customarily provided for in public offerings with selling stockholders. (ix) For purposes of this section 11.9(d), all references to OSI Common Stock (including the relative ownership of the holders of OSI Common Stock) shall include OSI Common Stock issuable pursuant to the exchange, redemption, retraction, call or purchase of PTI Exchangeable Shares and all references to stockholders of OSI shall include holders of such PTI Exchangeable Shares. The parties acknowledge and agree that in the event that any shareholder of PTI is determined to be eligible to participate in the secondary offering contemplated by this section 11.9(d), either (A) the parties shall amend this Combination Agreement and the exhibits hereto such that such eligible PTI shareholders shall receive OSI Common Stock rather than PTI Exchangeable Shares to the extent of their participation in such secondary offering or (B) OSI shall waive, and shall cause each of OSI ULC and PTI Holdco to waive, all time periods provided for the giving of notice in connection with the exchange, redemption, retraction, call or purchase of such PTI Exchangeable Shares in order to permit the holder of such PTI Exchangeable Shares to receive the underlying OSI Common Stock in sufficient time to deliver such OSI Common Stock at or prior to the closing of such secondary offering. 38 40 (x) If, prior to such time as the PTI Registration Statement is declared effective, the Holders are offered the opportunity to include any of their Registrable Securities in a Piggyback Registration pursuant to the Registration Rights Agreement, then the holders of PTI Exchangeable Shares shall be eligible to participate in such Piggyback Registration to the same extent and on an equivalent basis as such Holders are entitled to participate pursuant to the Registration Rights Agreement.

For the purposes of determining the exercise price per share of OSI Common Stock, the exercise price per share of PTI Common Shares subject to such Option shall be adjusted using the Canadian dollar exchange rate based upon the average of the noon buying rate expressed to the fourth decimal place for each of the Business Days in the Measurement Period as reported by the Bank of Canada. If the foregoing calculation results in a converted Option being exercisable for a fraction of a share of OSI Common Stock, then the number of shares of OSI Common Stock subject to such Option will be rounded down to the nearest whole number of shares, and the exercise price per whole share of OSI Common Stock will be as determined above. The obligations of PTI under the Options as so converted shall be assumed by OSI and OSI shall be substituted for PTI under the Option Agreements. Except as provided in this paragraph (d), the A-8 59 term and all other terms and conditions of the Options in effect immediately prior to giving effect to the Arrangement shall govern the Options. (u) PTI Holdco Sub shall acquire all of the issued and outstanding New PTI Shares from PTI Holdco in exchange for an equal number of common shares in the capital of PTI Holdco Sub. 2.2 TAX MATTERS (a) Holders of Exchangeable Shares who acquired them pursuant to the transfers referred to above (the "Eligible Holders") shall be entitled to make an election pursuant to subsection 85(1) of the ITA and any corresponding applicable provincial legislation with respect to the transfer of their New PTI Shares to PTI Holdco as provided above by providing two signed copies of the necessary election forms to PTI Holdco within 90 days following the Effective Date, duly completed with the details of the number of shares transferred, the adjusted cost base of those shares and such agreed amounts as shall be determined by the Eligible Holders for the purposes of such elections. Thereafter, subject to the election forms complying with the provisions of the ITA and any corresponding applicable provincial legislation, the forms will be signed by PTI Holdco and returned to the Eligible Holders within 30 days of receipt of such elections by PTI Holdco for filing with Canada Customs and Revenue Agency or any corresponding applicable provincial agency. (b) The applicable agreed amount for the purposes of any election to be made in accordance with Section 2.2(a) must comply with the following rules: (i) the agreed amount may not be less than the fair market value, on the Effective Date, of the consideration (other than Exchangeable Shares) received by an Eligible Holder for the disposition to PTI Holdco of the New PTI Shares to which the election applies; (ii) the agreed amount may not be less than the lesser of (A) the adjusted cost base to the Eligible Holder of the New PTI Shares to which the election applies, determined immediately before the time of the exchange, and (B) the fair market value of such New PTI Shares at that time; (iii) the agreed amount may not exceed the fair market value of the New PTI Shares to which the election applies at the time of the exchange.

Upon surrender to the Depositary of a certificate which immediately prior to the Effective Time represented outstanding PTI Common Shares, and such additional documents and instruments as the Depositary may reasonably require, the holder of such surrendered certificate shall be entitled to receive in exchange therefor, and the Depositary shall forthwith deliver to such holder, a certificate representing that number (rounded down to the nearest whole number) of Exchangeable Shares which such holder has the right to receive pursuant to the Arrangement (together with any dividends or distributions with respect thereto pursuant to Section 4.2 and any cash in lieu of fractional Exchangeable Shares pursuant to Section 4.3), and any certificate so surrendered shall forthwith be canceled. In the event of a transfer of ownership of PTI Common Shares which is not registered in the transfer records of PTI, a certificate representing the proper number of Exchangeable Shares (together with any dividends or distributions with respect thereto pursuant to Section 4.2 and any cash in lieu of fractional Exchangeable Shares pursuant to Section 4.3) shall be delivered to a transferee if the certificate representing such PTI Common Shares is presented to the Depositary, accompanied by all documents required to evidence and effect such transfer.

Until surrendered as contemplated by this Section 4.4, each certificate held by a U.S. PTI Shareholder which immediately prior to the Effective Time represented outstanding PTI Common Shares shall be deemed at any time after the Effective Time, but subject to Section 4.8, to represent only the right to receive upon such surrender (a) the certificate representing shares of OSI Common Stock as contemplated by this Section 4.4, (b) a cash payment in lieu of any fractional share of OSI Common Stock A-11 62 as contemplated by Section 4.6 and (c) any dividends or distributions with a record date after the Effective Time theretofore paid or payable with respect to OSI Common Stock as contemplated by Section 4.5. 4.5 DIVIDENDS AND OTHER DISTRIBUTIONS No dividends or other distributions declared or made after the Effective Time with respect to the OSI Common Stock with a record date after the Effective Time shall be paid to the U.S. PTI Shareholder of any formerly outstanding PTI Common Shares which were not exchanged pursuant to Section 2.1, and no cash payment in lieu of fractional shares shall be paid to any such holder pursuant to Section 4.6 (and no interest will be earned and payable thereon), unless and until the certificate representing such PTI Common Shares shall be surrendered in accordance with Section 4.4.

In lieu of any such fractional interests, each U.S. PTI Shareholder entitled thereto will receive an amount of cash (rounded to the nearest whole cent), without interest, equal to the product of (a) such fractional interest, multiplied by (b) the OSI IPO Price, such amount to be provided to the Depositary by OSI upon request. 4.7 LOST CERTIFICATES If any certificate which immediately prior to the Effective Time represented outstanding PTI Common Shares which were exchanged pursuant to Section 2.1 has been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such certificate to be lost, stolen or destroyed, the Depositary will issue in exchange for such lost, stolen or destroyed certificate, certificates representing Exchangeable Shares (together with any dividends or distributions with respect thereto pursuant to Section 4.2 and any cash in lieu of a fractional Exchangeable Share pursuant to Section 4.3) or, in the case of a U.S. PTI Shareholder, certificates representing shares of OSI Common Stock (together with any dividends or distributions with respect thereto pursuant to Section 4.5 and any cash in lieu of a fractional share of OSI Common Stock pursuant to Section 4.6) deliverable in respect thereof as determined in accordance with Section 2.1.

Payment of the total Liquidation Amount for such Exchangeable Shares shall be made by delivery to each holder, at the address of the holder recorded in the securities register of the Corporation for the Exchangeable Shares or by holding for pick up by the holder at the registered office of the Corporation or at any office of the Transfer Agent as may be specified by the Corporation in Schedule A hereto or by notice to the holders of Exchangeable Shares (provided that such delivery shall be made to the holder at its address recorded in the securities register of the Corporation or at the office of the transfer agent, if any, in the province in which the address of the holder recorded in the securities register of the Corporation is located), on behalf of the Corporation of the Exchangeable Share Consideration representing the total Liquidation Amount. On and after the Liquidation Date, the holders of the Exchangeable Shares shall cease to be holders of such Exchangeable Shares and shall not be entitled to exercise any of the rights of holders in respect thereof, other than the right to receive their proportionate part of the total Liquidation Amount, unless payment of the total Liquidation Amount for such Exchangeable Shares shall not be made upon presentation and surrender of share certificates in accordance with the foregoing provisions, in which case the rights of the B-10 91 holders shall remain unaffected until the total Liquidation Amount has been paid in the manner hereinbefore provided. The Corporation shall have the right at any time on or after the Liquidation Date to deposit or cause to be deposited the Exchangeable Share Consideration in respect of the Exchangeable Shares represented by certificates that have not at the Liquidation Date been surrendered by the holders thereof in a custodial account or for safe keeping, in the case of non-cash items, with any chartered bank or trust company in Canada. Upon such deposit being made, the of Exchangeable Shares after such deposit shall be limited to receiving their proportionate part of the total Liquidation Amount for such Exchangeable Shares so deposited, against presentation and surrender of the said certificates held by them, respectively, in accordance with the foregoing provisions. Upon such payment or deposit of such Exchangeable Share Consideration, the holders of the Exchangeable Shares shall thereafter be considered and deemed for all purposes to be the holders of the OSI Common Stock delivered to them. Notwithstanding the foregoing, until such payment or deposit of such Exchangeable Share Consideration, the holder shall be deemed to still be a holder of Exchangeable Shares for purposes of all voting rights with respect thereto under the Voting and Exchange Trust Agreement. 5.3 After the Corporation has satisfied its obligations to pay the holders of the Exchangeable Shares the Liquidation Amount per Exchangeable Share, such holders shall not be entitled to share in any further distribution of the assets of the Corporation. 5.4 If OSI or OSI ULC exercises the Liquidation Call Right, each holder of Exchangeable Shares shall be obligated to sell the Exchangeable Shares held by such holder to OSI or OSI ULC, as the case may be, on the Liquidation Date on payment to such holder by OSI or OSI ULC, as the case may be, of the Exchangeable Share Consideration representing the Liquidation Call Purchase Price for each Exchangeable Share. ARTICLE 6 RETRACTION OF EXCHANGEABLE SHARES BY HOLDER 6.1 A holder of Exchangeable Shares shall be entitled at any time after the effectiveness of a Registration Statement under the Securities Act of 1933 registering the issuance of shares of OSI Common Stock issuable pursuant to the provisions attaching to the Exchangeable Shares or prior thereto with the written consent of the Corporation, subject to applicable law and the exercise by OSI or OSI ULC of the Retraction Call Right (which, if exercised by OSI or OSI ULC, shall be binding on the holder of Exchangeable Shares) and otherwise upon compliance with the provisions of this Article 6, to require the Corporation to redeem any or all of the Exchangeable Shares registered in the name of such holder for an amount equal to the Exchangeable Share Price applicable on the last Business Day prior to the Retraction Date (the "Retraction Price") which as set forth in Section 6.4, shall be fully paid and satisfied by the delivery by or on behalf of the Corporation of the Exchangeable Share Consideration representing such holder's Retraction Price. In connection with payment of the Retraction Price, the Corporation shall be entitled to liquidate some of the OSI Common Stock that would otherwise be deliverable as Exchangeable Share Consideration to the particular holder of B-11 92 Exchangeable Shares in order to fund any statutory withholding tax obligation. To effect such redemption, the holder shall present and surrender at the registered office of the Corporation or at any office of the Transfer Agent as may be specified by the Corporation in Schedule A hereto or by notice to the holders of Exchangeable Shares the certificate or certificates representing the Exchangeable Shares which the holder desires to have the Corporation redeem, together with such other documents and instruments as may be required to effect a transfer of Exchangeable Shares under applicable law and the by-laws of the Corporation and such additional documents and instruments as the Transfer Agent may reasonably require, and together with a duly executed statement (the "Retraction Request") in the form of Schedule "A" hereto or in such other form as may be acceptable to the Corporation: (a) specifying that the holder desires to have all or any number specified therein of the Exchangeable Shares represented by such certificate or certificates (the "Retracted Shares") redeemed by the Corporation; (b) stating the Business Day on which the holder desires to have the Corporation redeem the Retracted Shares (the "Retraction Date"), provided that the Retraction Date shall be not less than three Business Days nor more than 10 Business Days after the date on which the Retraction Request is received by the Corporation and further provided that, in the event that no such Business Day is specified by the holder in the Retraction Request, the Retraction Date shall be deemed to be the tenth Business Day after the date on which the Retraction Request is received by the Corporation; and (c) acknowledging the overriding right (the "Retraction Call Right") of OSI or OSI ULC to purchase all but not less than all the Retracted Shares directly from the holder and that the Retraction Request shall be deemed to be a revocable offer by the holder to sell the Retracted Shares in accordance with the Retraction Call Right on the terms and conditions set out in Section 6.3 below. 6.2 Subject to the exercise by OSI or OSI ULC of the Retraction Call Right, upon receipt by the Corporation or the Transfer Agent in the manner specified in Section 6.1 hereof of a certificate or certificates representing the number of Exchangeable Shares which the holder desires to have the Corporation redeem, together with a Retraction Request, and provided that the Retraction Request is not revoked by the holder in the manner specified in Section 6.7, the Corporation shall redeem the Retracted Shares effective at the close of business on the Retraction Date and shall cause to be delivered to such holder the total Retraction Price with respect to such shares in accordance with Section 6.4 hereof. If only a part of the Exchangeable Shares represented by any certificate are redeemed or purchased by OSI or OSI ULC pursuant to the Retraction Call Right, a new certificate for the balance of such Exchangeable Shares shall be issued to the holder at the expense of the Corporation. 6.3 Upon receipt by the Corporation of a Retraction Request, the Corporation shall immediately notify OSI and OSI ULC thereof. In order to exercise the Retraction Call Right, OSI or OSI ULC must notify the Corporation in writing of its determination to do B-12 93 so (the "OSI Call Notice") within two Business Days of such notification. If OSI or OSI ULC does not so notify the Corporation within such two Business Days, the Corporation will notify the holder as soon as possible thereafter that neither OSI nor OSI ULC will exercise the Retraction Call Right. If OSI or OSI ULC delivers the OSI Call Notice within such two Business Days, and provided that the Retraction Request is not revoked by the holder in the manner specified in Section 6.7 hereof, the Retraction Request shall thereupon be considered only to be an offer by the holder to sell the Retracted Shares to OSI or OSI ULC, as the case may be, in accordance with the Retraction Call Right. In such event, the Corporation shall not redeem the Retracted Shares and OSI or OSI ULC, as the case may be, shall purchase from such holder and such holder shall sell to OSI or OSI ULC, as the case may be, on the Retraction Date the Retracted Shares for a purchase price per share (the "Purchase Price") equal to the Retraction Price, which as set forth in Section 6.4 hereof, shall be fully paid and satisfied by the delivery by or on behalf of OSI or OSI ULC, as the case may be, of the Exchangeable Share Consideration representing such holder's Purchase Price. For the purposes of completing a purchase pursuant to the Retraction Call Right, OSI or OSI ULC, as the case may be, shall deposit with the Transfer Agent, on or before the Retraction Date, the Exchangeable Share Consideration representing the total Purchase Price. Provided that such Exchangeable Share Consideration has been so deposited with the Transfer Agent, the closing of the purchase and sale of the Retracted Shares pursuant to the Retraction Call Right shall be deemed to have occurred as at the close of business on the Retraction Date and, for greater certainty, no redemption by the Corporation of such Retracted Shares shall take place on the Retraction Date. In the event that OSI or OSI ULC, as the case may be, does not deliver a OSI Call Notice within two Business Days or otherwise comply with these Exchangeable Share provisions in respect thereto, and provided that Retraction Request is not revoked by the holder in the manner specified in Section 6.7 hereof, the Corporation shall redeem the Retracted Shares on the Retraction Date and in the manner otherwise contemplated in this Article 6. 6.4 Subject to receipt by the Corporation of the Retracted Shares, OSI or OSI ULC, as the case may be, the Corporation, OSI or OSI ULC, as the case may be, shall deliver or cause the Transfer Agent to deliver to the relevant holder, at the address of the holder recorded in the securities register of the Corporation for the Exchangeable Shares or at the address specified in the holder's Retraction Request or by holding for pick up by the holder at the registered office of the Corporation or at any office of the Transfer Agent as may be specified by the holder in Schedule A hereto, in each case on or before two Business Days after the Retraction Date, the Exchangeable Share Consideration representing the total Retraction Price or the total Purchase Price, as the case may be, and such delivery of such Exchangeable Share Consideration to the Transfer Agent shall be deemed to be payment of and shall satisfy and discharge all liability for the total Retraction Price or total Purchase Price, as the case may be, except as to any cheque included therein which is not paid on due presentation. 6.5 On and after the close of business on the Retraction Date, the holder of the Retracted Shares shall cease to be a holder of such Retracted Shares and shall not be entitled to exercise any of the rights of a holder in respect thereof, other than the right to receive such holder's proportionate part of the total Retraction Price or total Purchase Price, as B-13 94 the case may be, unless upon presentation and surrender of certificates in accordance with the foregoing provisions, payment of the total Retraction Price or the total Purchase Price, as the case may be, shall not be made, in which case the rights of such holder shall remain unaffected until the Exchangeable Share Consideration representing the total Retraction Price or the total Purchase Price, as the case may be, has been paid in the manner hereinbefore provided. On and after the close of business on the Retraction Date, provided that presentation and surrender of certificates and payment of the Exchangeable Share Consideration representing the total Retraction Price or the total Purchase Price, as the case may be, has been made in accordance with the foregoing provisions, the holder of the Retracted Shares so redeemed by the Corporation or purchased by OSI or OSI ULC shall thereafter be considered and deemed for all purposes to be a holder of the OSI Common Stock delivered to it. Notwithstanding the foregoing, until such payment of such Exchangeable Share Consideration to the holder, the holder shall be deemed to still be a holder of Exchangeable Shares for purposes of all voting rights with respect thereto under the Voting and Exchange Trust Agreement. 6.6 Notwithstanding any other provision of this Article 6, the Corporation shall not be obligated to redeem Retracted Shares specified by a holder in a Retraction Request to the extent that such redemption of Retracted Shares would be contrary to liquidity or solvency requirements or other provisions of applicable law. If the Corporation believes that on any Retraction Date it would not be permitted by any of such provisions to redeem the Retracted Shares tendered for redemption on such date, and provided that neither OSI nor OSI ULC shall have exercised the Retraction Call Right with respect to the Retracted Shares, the Corporation shall only be obligated to redeem Retracted Shares specified by a holder in a Retraction Request to the extent of the maximum number that may be so redeemed (rounded down to a whole number of shares) as would not be contrary to such provisions and shall notify the holder as soon as is reasonably practical but in any event not later than one Business Day prior to the Retraction Date as to the number of Retracted Shares which will not be redeemed by the Corporation. In any case in which the redemption by the Corporation of Retracted Shares would be contrary to liquidity or solvency requirements or other provisions of applicable law, the Corporation shall redeem Retracted Shares in accordance with Section 6.2 of these share provisions on a pro rata basis and shall issue to each holder of Retracted Shares a new certificate, at the expense of the Corporation, representing the Retracted Shares not redeemed by the Corporation pursuant to Section 6.2 hereof. Provided that the Retraction Request is not revoked by the holder in the manner specified in Section 6.7 hereof, the holder of any such Retracted Shares not redeemed by the Corporation pursuant to Section 6.2 hereof as a result of liquidity or solvency requirements or applicable law shall be deemed by giving the Retraction Request to require OSI or OSI ULC, as the case may be, to purchase such Retracted Shares from such holder on the Retraction Date or as soon as practicable thereafter on payment by OSI or OSI ULC, as the case may be, to such holder of the Purchase Price for each such Retracted Share, all as more specifically provided in the Voting and Exchange Trust Agreement, and OSI or OSI ULC shall make such purchase. 6.7 A holder of Retracted Shares may, by notice in writing given by the holder to the Corporation before the close of business on the Business Day immediately preceding the Retraction Date, withdraw its Retraction Request in which event such Retraction Request B-14 95 shall be null and void and, for greater certainty, the revocable offer constituted by the Retraction Request to sell the Retracted Shares to OSI or OSI ULC, as the case may be, shall be deemed to have been revoked. ARTICLE 7 REDEMPTION OF EXCHANGEABLE SHARES BY THE CORPORATION 7.1 Subject to applicable law, and if neither OSI or OSI ULC exercises the Redemption Call Right (which, if exercised, shall be binding on the holders of Exchangeable Shares), the Corporation shall on the Automatic Redemption Date redeem the whole of the then outstanding Exchangeable Shares for an amount equal to the Exchangeable Share Price applicable on the last Business Day prior to the Automatic Redemption Date (the "Redemption Price") which, as set forth in Section 7.3 hereof, shall be fully paid and satisfied by the delivery by or on behalf of the Corporation of the Exchangeable Share Consideration representing the total Redemption Price. In connection with payment of the Exchangeable Share Consideration representing the Redemption Price, the Corporation shall be entitled to liquidate some of the OSI Common Stock which would otherwise be deliverable as Exchangeable Share Consideration to the particular holder of Exchangeable Shares in order to fund any statutory withholding tax obligation. 7.2 In any case of a redemption of Exchangeable Shares under this Article 7, the Corporation, or the Transfer Agent on behalf of the Corporation, shall, at least 60 days before an Automatic Redemption Date described in clause (a) or (b) of the definition of Automatic Redemption Date or at least such number of days before an Automatic Redemption Date described in clause (c), (d) or (e) of the definition of Automatic Redemption Date as the Board of Directors of the Corporation may determine to be reasonably practicable in the circumstances, send or cause to be sent to each registered holder of Exchangeable Shares a notice in writing of the redemption or possible redemption by the Corporation or the purchase by OSI or OSI ULC under the Redemption Call Right, as the case may be, of the Exchangeable Shares held by such holder. Such notice shall set out the Redemption Price or the Redemption Call Purchase Price, as the case may be, the Automatic Redemption Date and, if applicable, particulars of the Redemption Call Right. In the case of any notice given in connection with a possible Automatic Redemption Date as described in clause (c), (d) or (e) of the definition of Automatic Redemption Date, such notice will be given contingently and will be withdrawn if the contingency does not occur. 7.3 On or after the Automatic Redemption Date, and subject to the exercise by OSI or OSI ULC of the Redemption Call Right, the Corporation shall cause to be delivered to the holders of the Exchangeable Shares to be redeemed the Exchangeable Share Consideration representing the Redemption Price for each such Exchangeable Share upon presentation and surrender at the registered office of the Corporation or at any office of the Transfer Agent as may be specified by the Corporation in such notice of the certificates representing such Exchangeable Shares, together with such other documents and instruments as may be required to effect a transfer of Exchangeable Shares under applicable law and the by-laws of the Corporation and such additional documents and B-15 96 instruments as the Transfer Agent may reasonably require (provided that such presentation and surrender shall be deemed to be valid if made at the office of the Transfer Agent, if any, in the province in which the address of the holder of Exchangeable Shares is recorded on the books of the Corporation). Payment of the total Redemption Price for such Exchangeable Shares shall be made by delivery to each holder, at the address of the holder recorded in the securities register or at any office of the Transfer Agent as may be specified by the Corporation in such notice, on behalf of the Corporation, of the Exchangeable Share Consideration representing the total Redemption Price (provided that if payment is made by delivery of the Exchangeable share Consideration to the Transfer Agent, such delivery shall be made at the office of the Transfer Agent, if any, in the province in which the address of the holder of Exchangeable Shares is recorded on the books of the Corporation). On and after the Automatic Redemption Date, the holders of the Exchangeable Shares called for redemption shall cease to be holders of such Exchangeable Shares and shall not be entitled to exercise any of the rights of holders in respect thereof, other than the right to receive their proportionate part of the Exchangeable Share Consideration representing the total Redemption Price, unless payment of the Exchangeable Share Consideration representing the total Redemption Price for such Exchangeable Shares shall not be made upon presentation and surrender of certificates in accordance with the foregoing provisions, in which case the rights of the holders shall remain unaffected until the Exchangeable Share Consideration representing the total Redemption Price has been paid in the manner hereinbefore provided. The Corporation shall have the right at any time after the sending of notice of its intention to redeem the Exchangeable Shares as aforesaid to deposit or cause to be deposited the Exchangeable Share Consideration with respect to the Exchangeable Shares so called for redemption, or of such of the said Exchangeable Shares represented by certificates that have not at the date of such deposit been surrendered by the holders thereof in connection with such redemption, in a custodial account or for safe keeping, in the case of non-cash items, with any chartered bank or trust company in Canada named in such notice. Upon the later of such deposit being made and the Automatic Redemption Date, the Exchangeable Shares in respect whereof such deposit shall have been made shall be redeemed and the rights of the holders thereof after such deposit or Automatic Redemption Date, as the case may be, shall be limited to receiving their proportionate part of the Exchangeable Share Consideration representing the total Redemption Price for such Exchangeable Shares so deposited, against presentation and surrender of the said certificates held by them, respectively, in accordance with the foregoing provisions. Upon such payment or deposit of such Exchangeable Share Consideration, the holders of the Exchangeable Shares shall thereafter be considered and deemed for all purposes to be holders of the OSI Common Stock delivered to them. Notwithstanding the foregoing, until such payment or deposit of such Exchangeable Share Consideration is made, the holder shall be deemed to still be a holder of Exchangeable Shares for purposes of all voting rights with respect thereto under the Voting and Exchange Trust Agreement. 7.4 If OSI or OSI ULC exercises the Redemption Call Right, each holder of Exchangeable Shares shall be obligated to sell all the Exchangeable Shares held by such holder to OSI or OSI ULC, as the case may be, on the Automatic Redemption Date against payment to B-16 97 such holder by OSI or OSI ULC of the Exchangeable Share Consideration representing the Redemption Call Purchase Price for each such share. ARTICLE 8 VOTING RIGHTS 8.1 Except as required by applicable law and the provisions hereof, the holders of the Exchangeable Shares shall not be entitled as such to receive notice of or to attend any meeting of the shareholders of the Corporation or to vote at any such meeting. ARTICLE 9 AMENDMENT AND APPROVAL 9.1 The rights, privileges, restrictions and conditions attaching to the Exchangeable Shares may be added to, changed or removed but, except as hereinafter provided, only with the approval of the holders of the Exchangeable Shares given as hereinafter specified. 9.2 Any approval given by the holders of the Exchangeable Shares to add to, change or remove any right, privilege, restriction or condition attaching to the Exchangeable Shares or any other matter requiring the approval or consent of the holders of the Exchangeable Shares shall be deemed to have been sufficiently given if it shall have been given in accordance with applicable law subject to a minimum requirement that such approval be evidenced by resolution passed by not less than 66 2/3% of the votes cast on such resolution by persons represented in person or by proxy at a meeting of holders of Exchangeable Shares (excluding Exchangeable Shares beneficially owned by OSI or its Subsidiaries) duly called and held at which the holders of at least 50% of the outstanding Exchangeable Shares at that time are present or represented by proxy. If at any such meeting the holders of at least 50% of the outstanding Exchangeable Shares at that time are not present or represented by proxy within one-half hour after the time appointed for such meeting, then the meeting shall be adjourned to such date not less than 10 days thereafter and to such time and place as may be designated by the Chairman of such meeting. At such adjourned meeting, the holders of Exchangeable Shares present or represented by proxy thereat may transact the business for which the meeting was originally called and a resolution passed thereat by the affirmative vote of not less than 66 2/3% of the votes cast on such resolution by persons represented in person or by proxy at such meeting (excluding Exchangeable Shares beneficially owned by OSI or its Subsidiaries) shall constitute the approval or consent of the holders of the Exchangeable Shares.

In the event of the exercise of the Liquidation Call Right by OSI or OSI ULC, each holder shall be obligated to sell all the Exchangeable Shares held by such holder to OSI or OSI ULC on the Liquidation Date on payment by OSI or OSI ULC to the holder of the Liquidation Call Purchase Price for each such share.

If OSI or OSI ULC does not exercise the Liquidation Call Right in the manner described above, on the Liquidation Date the holders of the Exchangeable Shares will be entitled to receive in exchange therefor the liquidation price otherwise payable by the Corporation in connection with the liquidation, dissolution or winding-up of the Corporation pursuant to Article 5 of the Exchangeable Share Provisions.

In the event of the exercise of the Redemption Call Right by OSI or OSI ULC, each holder shall be obligated to sell all the Exchangeable Shares held by the holder to OSI or OSI ULC on the Automatic Redemption Date on payment by OSI or OSI ULC to the holder of the Redemption Call Purchase Price for each such share. (b) To exercise the Redemption Call Right, OSI or OSI ULC must notify the Transfer Agent in writing, as agent for the holders of Exchangeable Shares, and the Corporation of the OSI's or OSI ULC's intention to exercise such right not later than the date by which the Corporation is required to give notice of the Automatic Redemption Date. The Transfer Agent will notify the holders of the Exchangeable Shares as to whether or not OSI or OSI ULC has exercised the Redemption Call Right forthwith after the date by which the same may be exercised by OSI or OSI ULC.

B-26 107 (c) For the purposes of completing the purchase of the Exchangeable Shares pursuant to the Redemption Call Right, OSI or OSI ULC shall deposit with the Transfer Agent, on or before the Automatic Redemption Date, the Exchangeable Share Consideration representing the total Redemption Call Purchase Price. Provided that such Exchangeable Share Consideration has been so deposited with the Transfer Agent, on and after the Automatic Redemption Date, the rights of each holder of Exchangeable Shares will be limited to receiving such holder's proportionate part of the total Redemption Call Purchase Price payable by OSI or OSI ULC upon presentation and surrender by the holder of certificates representing the Exchangeable Shares held by such holder and the holder shall on and after the Automatic Redemption Date be considered and deemed for all purposes to be the holder of the OSI Common Stock delivered to such holder. Upon surrender to the Transfer Agent of a certificate or certificates representing Exchangeable Shares, together with such other documents and instruments as may be required to effect a transfer of Exchangeable Shares under the Act and the by-laws of the Corporation and such additional documents and instruments as the Transfer Agent may reasonably require, the holder of such surrendered certificate or certificates shall be entitled to receive in exchange therefor, and the Transfer Agent on behalf of OSI or OSI ULC shall deliver to such holder, the Exchangeable Share Consideration to which such holder is entitled. If OSI or OSI ULC does not exercise the Redemption Call Right in the manner described above, on the Automatic Redemption Date, the holders of the Exchangeable Shares will be entitled to receive in exchange therefor the redemption price otherwise payable by the Corporation in connection with the redemption of the Exchangeable Shares pursuant to Article 7 of the Exchangeable Share Provisions. Notwithstanding the foregoing, until such Exchangeable Share Consideration is delivered to the holder, the holder shall be deemed to still be a holder of Exchangeable Shares for purposes of all voting rights with respect thereto under the Voting and Exchange Trust Agreement. 1.5 Retraction Call Right OSI or OSI ULC shall have the overriding right, notwithstanding the proposed redemption of Exchangeable Shares by the Corporation pursuant to Article 6 of the Exchangeable Share Provisions, to purchase directly from the holder (other than OSI or any Subsidiary thereof) of Exchangeable Shares all but not less than all of the Retracted Shares in accordance with Section 6.3 of the Exchangeable Share Provisions.

From and after the first anniversary of the Effective Date (or such earlier date as such shares or securities may be issued and delivered pursuant to C-5 115 Articles 5 or 7 of the Exchangeable Share Provisions, pursuant to the Exchange Rights or the Automatic Exchange Rights or pursuant to the Liquidation Call Right or the Redemption Call Right), 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 hereof) to be delivered hereunder (including, for greater certainty, pursuant to Exchangeable Share Provisions, or 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. 2.7 EQUIVALENCE (a) OSI will not: (i) issue or distribute shares of OSI Common Stock (or securities exchangeable for or convertible into or carrying rights to acquire shares of OSI Common Stock) to the holders of all or substantially all of the then outstanding shares of OSI Common Stock by way of stock dividend or other distribution; or (ii) issue or distribute rights, options or warrants to the holders of all or substantially all of the then outstanding shares of OSI Common Stock entitling them to subscribe for or to purchase shares of OSI Common Stock (or securities exchangeable for or convertible into or carrying rights to acquire shares of OSI Common Stock); or (iii) issue or distribute to the holders of all or substantially all of the then outstanding shares of OSI Common Stock (A) shares or securities of OSI of any class other than OSI Common Stock (other than shares convertible into or exchangeable for or carrying rights to acquire shares of OSI Common Stock), (B) rights, options or warrants other than those referred to in subsection 2.7 (a) (ii) above, (C) evidences of indebtedness of OSI or (D) assets of OSI; unless (iv) one or both of OSI and PTI Holdco is permitted under applicable law to issue or distribute the economic equivalent on a per share basis of such rights, options, warrants, securities, shares, evidences of indebtedness or other assets to the holders of the Exchangeable Shares; and (v) one or both of OSI and PTI Holdco shall issue or distribute the economic equivalent on a per share basis of such rights, options, warrants, securities, C-6 116 shares, evidences of indebtedness or other assets simultaneously to the holders of the Exchangeable Shares. (b) OSI will not: (i) subdivide, redivide or change the then outstanding shares of OSI Common Stock into a greater number of shares of OSI Common Stock; or (ii) reduce, combine or consolidate or change the then outstanding shares of OSI Common Stock into a lesser number of shares of OSI Common Stock; or (iii) reclassify or otherwise change the shares of OSI Common Stock or effect an amalgamation, merger, reorganization or other transaction involving or affecting the shares of OSI Common Stock; unless (iv) PTI Holdco is permitted under applicable law to simultaneously make the same or an economically equivalent change to, or in the rights of the holders of, the Exchangeable Shares; and (v) the same or an economically equivalent change is simultaneously made to, or in the rights of the holders of, the Exchangeable Shares. (c) OSI will ensure that the record date for any event referred to in section 2.7(a) or 2.7(b) above, or (if no record date is applicable for such event) the effective date for any such event, is not less than 10 Business Days after the date on which such event is declared or announced by OSI (with simultaneous notice thereof to be given by OSI to PTI Holdco). (d) The Board of Directors of PTI Holdco shall determine, in good faith and in its sole discretion, economic equivalence for the purposes of any event referred to in Section 2.7(a) or 2.7(b) above and each such determination shall be conclusive and binding on OSI. In making each such determination, the following factors shall, without excluding other factors determined by the Board of Directors of PTI Holdco to be relevant, be considered by the Board of Directors of PTI Holdco: (i) in the case of any stock dividend or other distribution payable in OSI Common Stock, the number of such shares issued in proportion to the number of shares of OSI Common Stock previously outstanding; (ii) in the case of the issuance or distribution of any rights, options or warrants to subscribe for or purchase OSI Common Stock (or securities exchangeable for or convertible into or carrying rights to acquire OSI Common Stock), the relationship between the exercise price of each such right, option or warrant and the current market value (as determined by the C-7 117 Board of Directors of PTI Holdco in the manner contemplated below) of a share of OSI Common Stock; (iii) in the case of the issuance or distribution of any other form of property (including without limitation any share or securities of OSI of any class other than OSI Common Stock, any rights, options or warrants other than those referred to in Section 2.7(d)(ii) above, any evidences of indebtedness of OSI or any assets of OSI), the relationship between the fair market value (as determined by the Board of Directors of PTI Holdco in the manner above contemplated) of such property to be issued or distributed with respect to each outstanding share of OSI Common Stock and the current market value (as determined by the Board of Directors of PTI Holdco in the manner contemplated below) of a share of OSI Common Stock; (iv) in the case of any subdivision, redivision or change of the then outstanding shares of OSI Common Stock into a greater number of shares of OSI Common Stock or the reduction, combination, consolidation or change of the then outstanding shares of OSI Common Stock into a lesser number of shares of OSI Common Stock or any amalgamation, merger, reorganization or other transaction affecting shares of OSI Common Stock, the effect thereof upon the then outstanding shares of OSI Common Stock; and (v) in all such cases, the general taxation consequences of the relevant event to holders of Exchangeable Shares to the extent that such consequences may differ from the taxation consequences to holders of shares of OSI Common stock as a result of differences between taxation laws of Canada and the United States (except for any differing consequences arising as a result of differing marginal taxation rates and without regard to the individual circumstances of holders of Exchangeable Shares). For purposes of the foregoing determinations, the current market value of any security listed and traded or quoted on a securities exchange shall be the average of the closing price of such security during a period of not less than 20 consecutive trading days ending not more than five trading days before the date of determination on the principal securities exchange on which such securities are listed and traded or quoted; provided, however, that if in the opinion of the Board of Directors of PTI Holdco the public distribution or trading activity of such securities during such period does not create a market which reflects the fair market value of such securities, then the current market value thereof shall be determined by the Board of Directors of PTI Holdco, in good faith and in its sole discretion, and provided further than any such determination by the Board of Directors of PTI Holdco shall be conclusive and binding on OSI. (e) PTI Holdco agrees that, to the extent required, upon due notice from OSI, PTI Holdco will use its best efforts to take or cause to be taken such steps as may be C-8 118 necessary for the purposes of ensuring that appropriate dividends are paid or other distributions are made by PTI Holdco, or subdivisions, redivisions or changes are made to the Exchangeable Shares, in order to implement the required economic equivalence with respect to the OSI Common Stock and Exchangeable Shares as provided for in this Section 2.7. 2.8 TENDER OFFERS, ETC. In the event that a tender offer, share exchange offer, issuer bid, take-over bid or similar transaction with respect to OSI Common Stock (an "Offer") is proposed by OSI or is proposed to OSI or its shareholders and is recommended by the Board of Directors of OSI, or is otherwise effected or to be effected with the consent or approval of the Board of Directors of OSI, and the Exchangeable Shares are not redeemed by PTI Holdco or purchased by OSI or OSI ULC pursuant to the Redemption Call Right, OSI shall, expeditiously and in good faith, take all such actions and do all such things as are necessary or desirable to enable and permit holders of Exchangeable Shares to participate in such Offer to the same extent and on an equivalent basis as the holders of shares of OSI Common Stock, without discrimination, including, without limiting the generality of the foregoing, OSI will use its good faith efforts expeditiously to (and shall, in the case of a transaction proposed by OSI or where OSI is a participant in the negotiation thereof) ensure that holders of Exchangeable Shares may participate in all such Offers without being required to retract Exchangeable Shares as against PTI Holdco (or, if so required, to ensure that any such retraction shall be effective only upon, and shall be conditional upon, the closing of the Offer and only to the extent necessary to tender or deposit to the Offer). 2.9 OWNERSHIP OF OUTSTANDING SHARES Without the prior approval of PTI Holdco and the prior approval of the holders of the Exchangeable Shares given in accordance with Section 9.2 of the Exchangeable Share Provisions, OSI covenants and agrees in favor of PTI Holdco that, as long as any outstanding Exchangeable Shares are owned by any person or entity other than OSI or any of its Subsidiaries, OSI, alone or together with any direct or indirect wholly-owned subsidiary of OSI, will be and remain the beneficial owner of all issued and outstanding securities of PTI Holdco. Notwithstanding the foregoing, OSI shall not be in violation of this Section if any person or group of persons acting jointly or in concert acquires OSI Common Stock pursuant to any merger of OSI pursuant to which OSI was not the surviving corporation. 2.10 OSI NOT TO VOTE EXCHANGEABLE SHARES OSI covenants and agrees that it will appoint and cause to be appointed proxy holders with respect to all Exchangeable Shares held by OSI and its Subsidiaries for the sole purpose of attending each meeting of holders of Exchangeable Shares in order to be counted as part of the quorum for each such meeting.

To cause the exercise of the Exchange Right by the Trustee, the Holder shall deliver to the Trustee, in person or by certified or registered mail, at its principal transfer offices in Calgary, Alberta or at such other places in Canada as the Trustee may from time to time designate by written notice to the Holders, the certificates representing the Exchangeable Shares which such Holder desires OSI to purchase, duly endorsed in blank, and accompanied by such other documents and instruments as may be required to effect a transfer of Exchangeable Shares under applicable law and the by-laws of PTI Holdco and such additional documents and instruments as the Trustee may reasonably require, together with: (a) a duly completed form of notice of exercise of the Exchange Right, contained on the reverse of or attached to the Exchangeable Share certificates, stating: (i) that the Holder thereby instructs the Trustee to exercise the Exchange Right so as to require OSI or OSI ULC to purchase from the Holder the number of Exchangeable Shares specified therein, (ii) that such Holder has good title to and owns all such Exchangeable Shares to be acquired by OSI or OSI ULC free and clear of all liens, claims, encumbrances, security interests and adverse claims or interests, (iii) the names in which the certificates representing OSI Common Stock issuable in connection with the exercise of the Exchange Right are to be issued, and (iv) the names and addresses of the persons to whom the Exchangeable Share Consideration should be delivered; and (b) payment (or evidence satisfactory to the Trustee, PTI Holdco and OSI or OSI ULC of payment) of the taxes (if any) payable as contemplated by Section 5.8 of this agreement. If only a part of the Exchangeable Shares represented by any certificate or certificates delivered to the Trustee are to be purchased by OSI or OSI ULC under the Exchange Right, a new certificate for the balance of such Exchangeable Shares shall be issued to the Holder at the expense of PTI Holdco. D-12 136 5.6 DELIVERY OF EXCHANGEABLE SHARE CONSIDERATION; EFFECT OF EXERCISE Promptly after receipt of the certificates representing the Exchangeable Shares which the Holder desires OSI or OSI ULC to purchase under the Exchange Right (together with such documents and instruments of transfer and a duly completed form of notice of exercise of the Exchange Right), duly endorsed for transfer to OSI, the Trustee shall notify OSI, OSI ULC and PTI Holdco of its receipt of the same, which notice to OSI, OSI ULC and PTI Holdco shall constitute exercise of the Exchange Right by the Trustee on behalf of the Holder of such Exchangeable Shares, and OSI or OSI ULC shall immediately thereafter deliver or cause to be delivered to the Trustee, for delivery to the Holder of such Exchangeable Shares (or to such other persons, if any, properly designated by such Holder), the Exchangeable Share Consideration deliverable in connection with the exercise of the Exchange Right; provided, however, that no such delivery shall be made unless and until the Holder requesting the same shall have paid (or provided evidence satisfactory to the Trustee, PTI Holdco and OSI or OSI ULC of the payment of) the taxes (if any) payable as contemplated by Section 5.8 of this agreement. Immediately upon the giving of notice by the Trustee to OSI, OSI ULC and PTI Holdco of the exercise of the Exchange Right, as provided in this Section 5.6, (i) the closing of the transaction of purchase and sale contemplated by the Exchange Right shall be deemed to have occurred, (ii) OSI or OSI ULC shall be required to take all action necessary to permit it to occur, including delivery to the Trustee of the relevant Exchangeable Share Consideration, no later than the close of business on the third Business Day following the receipt by the Trustee of notice, certificates and other documents as aforesaid and (iii) the Holder of such Exchangeable Shares shall be deemed to have transferred to OSI or OSI ULC all of its right, title and interest in and to such Exchangeable Shares and the related interest in the Trust Estate, shall cease to be a holder of such Exchangeable Shares and shall not be entitled to exercise any of the rights of a holder in respect thereof, other than the right to receive his proportionate part of the total purchase price therefor, unless such Exchangeable Share Consideration is not delivered by OSI or OSI ULC to the Trustee by the date specified above, in which case the rights of the Holder shall remain unaffected until such Exchangeable Share Consideration is delivered by OSI or OSI ULC and any cheque included therein is paid. 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-13 137 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-14 138 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-15 139 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-16 140 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-17 141 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-18 142 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-19 143 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-20 144 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-21 145 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-22 146 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-23 147 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-24 148 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-25 149 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.

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. If OSI or PTI Holdco shall fail to cause such notice to be mailed within 10 days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be mailed at the expense of OSI and PTI Holdco.

(a) Request for Registration.

(ii) Each Demand Request shall specify the type and number of shares of Registrable Securities proposed to be sold. Subject to Section 4(c), OSI shall file the Demand Registration as soon as reasonably practicable but in any event within 60 days after receiving a Demand Request (the "Required Filing Date") and shall use all commercially reasonable efforts to cause the same to be declared effective by the SEC as promptly as practicable after such filing. Subject to Section 2(b), if OSI has effected five Demand Registrations in response to the request of a Demand Holder, then OSI shall not be obligated to respond to further Demand Registrations in respect of Demand Holders pursuant to this Section. OSI shall not be obligated to effect more than one Demand Registration in any six month period. (b) Effective Registration and Expenses. Each registration that becomes effective will be counted as a Demand Registration. A registration will not count as a Demand Registration until it has become effective unless (i) prior to such effective time the Requesting Holders withdraw all their Registrable Securities for any reason other than (A) the inability or unreasonable delay of OSI in having such registration statement become effective or (B) the disclosure of material adverse information regarding OSI that was not known by such Requesting Holders at the time the request for such Demand Registration was E-4 162 made and (ii) the Requesting Holders elect not to pay all of OSI's Registration Expenses in connection with such withdrawn registration. If, after such registration has become effective, an offering of Registrable Securities pursuant to a registration is interfered with by any stop order, injunction or other order or requirement of the SEC or other governmental agency or court, such registration will not count as a Demand Registration; provided, however, that upon the termination or release of such stop order, injunction or interference, such registration will again be counted as a Demand Registration. (c) Selection of Underwriters. The offering of Registrable Securities pursuant to a Demand Registration may be in the form of a "firm commitment" underwritten offering. OSI shall select the book-running managing Underwriter and such additional Underwriters to be used in connection with the offering; provided that such selections shall be subject to the consent of Requesting Holders owning a majority of the Registrable Securities subject to such Demand Registration, which consent shall not be unreasonably withheld. (d) Priority on Demand Registrations. No securities to be sold for the account of any Person (including OSI) other than a Holder shall be included in a Demand Registration if the managing Underwriter or Underwriters shall advise the Requesting Holder in writing that, in its or their judgment, the inclusion of such securities may adversely affect the price or success of the offering in any significant or material respect (a "Material Adverse Effect"). Furthermore, in the event the managing Underwriter or Underwriters shall advise the Requesting Holder that even after exclusion of all securities of other Persons pursuant to the immediately preceding sentence, the amount of Registrable Securities proposed to be included in such Demand Registration by Holders electing to participate is sufficiently large to cause a Material Adverse Effect, the Registrable Securities of such Holders to be included in such Demand Registration shall be allocated pro rata among such Holders on the basis of the number of outstanding shares of OSI Common Stock requested to be included in such registration by each such Holder. SECTION 3 PIGGYBACK REGISTRATION. (a) If OSI proposes to file a registration statement under the Securities Act, including a Demand Registration, with respect to an offering of OSI Common Stock for cash by OSI for its own account or for the account of any of its equity holders (other than a registration statement on Form S-4 or S-8 or any substitute form that may be adopted by the SEC or any registration statement filed in connection with an exchange offer or offering of securities solely to OSI's existing security holders or any registration statement filed in connection with an exchange offer or offering of securities to holders of Exchangeable Shares) (the "PTI Registration Statement"), then OSI shall give written notice of such proposed filing to the Holders of the Registrable Securities as soon as practicable (but in no event less than 20 days before the anticipated initial filing date of such registration statement), and such notice shall offer such Holders the opportunity to register such number of Registrable Securities as each such Holder may request (a "Piggyback Registration"). On or before the 10th day following the receipt of such notice by the Holders, any Holder wishing to include any or all of its Registrable Securities in such registration statement shall give written notice to OSI stating the name of such Holder and the amount of such Holder's E-5 163 Registrable Securities to be included in such registration statement. Subject to Section 3(b), OSI shall include in each such Piggyback Registration all Registrable Securities requested to be included in the registration for such offering; provided, however, that OSI may at any time withdraw or cease proceeding with such registration without the consent of any Holder of Registrable Securities, notwithstanding the request of any such Holder to participate therein in accordance with this provision, if OSI determines in its sole discretion that such action is in the best interests of OSI and its stockholders (for this purpose, the interests of the Holders shall not be considered). Each Holder of Registrable Securities shall be permitted to withdraw all or part of such Holder's Registrable Securities from a Piggyback Registration at any time prior to the effective date thereof. (b) OSI shall use all commercially reasonable efforts to cause the managing Underwriter or Underwriters of a proposed underwritten offering to permit the Registrable Securities requested to be included in the registration statement for such offering under Section 3(a) ("Piggyback Securities"), to be included on the same terms and conditions as any similar securities included therein. Notwithstanding the foregoing, OSI shall not be required to include any Holder's Piggyback Securities in such offering unless such Holder accepts the terms of the underwriting agreement between OSI and the managing Underwriter or Underwriters and otherwise complies with the provisions of Section 8. If such offering is a Demand Registration pursuant to Section 2(a), then the provisions of Section 2(d) shall apply. In all other offerings that are underwritten, if the managing Underwriter or Underwriters of such proposed underwritten offering advise OSI in writing that in its or their opinion the total amount of securities, including Piggyback Securities, to be included in such offering is sufficiently large to cause a Material Adverse Effect, then in such event the securities to be included in such offering shall be allocated first to OSI, and then, to the extent that any additional securities can, in the opinion of such managing Underwriter or Underwriters, be sold without any such Material Adverse Effect, pro rata among the holders of Piggyback Securities on the basis of the number of outstanding shares of OSI Common Stock requested to be included in such registration by each such Holder. (c) Until such time as the PTI Registration Statement has been declared effective by the SEC, the holders of PTI Exchangeable Shares shall be deemed to be Holders hereunder for purposes of participation in Piggyback Registrations. The holders of PTI Exchangeable Shares shall have the same rights, duties and obligations of Holders with respect to Piggyback Registrations and shall be subject to the same limitations and restrictions thereon. The rights provided in this Section 3(c) shall terminate as to any particular holder of PTI Exchangeable Shares at such time as such holder ceases to be a holder of PTI Exchangeable Shares. SECTION 4 HOLDBACK AGREEMENTS. (a) Restrictions on Public Sale by Holder of Registrable Securities. Each Holder of Registrable Securities (whether or not such Registrable Securities are included in a registration statement pursuant hereto) agrees not to effect any direct or indirect (including through derivative transactions) sale or distribution of the issue being registered or of any securities convertible into or exchangeable or exercisable for such securities, including a sale E-6 164 pursuant to Rule 144 under the Securities Act, during the 14 days prior to, and during such period (up to 90 days) beginning on, the date of the final prospectus used with respect to any underwritten public offering of equity securities by the Company or any Holder of Registrable Securities if and to the extent requested by the managing Underwriter or Underwriters. (b) Restrictions on Public Sale by OSI and Others. OSI agrees not to effect any direct or indirect (including through derivative transactions) sale or distribution of any securities similar to those being registered, or any securities convertible into or exchangeable or exercisable for such securities, during the 14 days prior to, and during a period of up to 90 days, if requested by the managing underwriters, beginning on, the date of the final prospectus used with respect to any underwritten public offering of equity securities by the Company or any Holder of Registrable Securities (unless such sale or distribution is pursuant to such registration statement); provided, such restriction shall not affect OSI's ability to issue OSI Common Stock pursuant to the PTI Registration Statement. (c) Deferral of Filing. OSI may defer the filing (but not the preparation) of a registration statement required by Section 2 if (i) at the time OSI receives the Demand Request, OSI is engaged in confidential negotiations or other confidential business activities, disclosure of which would be required in such registration statement (but would not be required if such registration statement were not filed), and the Board of Directors of OSI determines in good faith that such disclosure would not be in the best interests of OSI and its stockholders, or (ii) prior to receiving the Demand Request, the Board of Directors had determined to effect a registered underwritten public offering of OSI's equity securities for OSI's account and OSI had taken substantial steps (including, but not limited to, selecting the managing Underwriter for such offering) and is proceeding with reasonable diligence to effect such offering. A deferral of the filing of a registration statement pursuant to this Section 4(c) shall be lifted, and the requested registration statement shall be filed forthwith, if, in the case of a deferral pursuant to clause (i) of the preceding sentence, the negotiations or other activities are disclosed or terminated, or, in the case of a deferral pursuant to clause (ii) of the preceding sentence, the proposed registration for OSI's account is abandoned. In order to defer the filing of a registration statement pursuant to this Section 4(c), OSI shall promptly, upon determining to seek such deferral, deliver to each Requesting Holder a certificate signed by the President of Company stating that OSI is deferring such filing pursuant to this Section 4(c). Within twenty days after receiving such certificate, the Requesting Holder may withdraw such request by giving notice to OSI; if withdrawn, the Demand Request shall be deemed not to have been made for all purposes of this Agreement. OSI may defer the filing of a particular registration statement pursuant to this Section 4(c) for a period of 45 days in any three month period and of all registration statements for a total of 90 days during any twelve month period. SECTION 5 REGISTRATION PROCEDURES. Whenever the Holders have requested that any Registrable Securities be registered pursuant to Section 2 hereof, OSI will, at its expense, use all commercially reasonable efforts to effect the registration and the sale of such Registrable Securities under the Securities Act in accordance with the intended method of disposition thereof as quickly as practicable, and in connection with any such request, OSI will as expeditiously as practicable: E-7 165 (a) prepare and file with the SEC a registration statement on any form for which OSI then qualifies or which counsel for OSI shall deem appropriate and which form shall be available for the sale of the Registrable Securities to be registered thereunder in accordance with the intended method of distribution thereof, and use all commercially reasonable efforts and proceed diligently and in good faith to cause such filed registration statement to become effective under the Securities Act; provided, however, that before filing a registration statement or prospectus or any amendments or supplements thereto, OSI will furnish to all Selling Holders and to one counsel reasonably acceptable to OSI selected by the Selling Holders, copies of all such documents proposed to be filed, which documents will be subject to the review of such counsel; (b) prepare and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective pursuant to Section 2 for a period (except as provided in the last paragraph of this Section 5) of not less than 180 consecutive days or, if shorter, the period terminating when all Registrable Securities covered by such registration statement have been sold (but not before the expiration of the applicable period referred to in Section 4(3) of the Securities Act and Rule 174 thereunder, if applicable) and comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement during such period in accordance with the intended methods of disposition by the Selling Holders thereof set forth in such registration statement; (c) furnish to each such Selling Holder one copy of such registration statement, and of each amendment and supplement thereto (in each case including one copy of all exhibits thereto), and such number of copies of the prospectus included in such registration statement (including each preliminary prospectus) as such Selling Holder may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such Selling Holder; (d) notify the Selling Holders promptly, and (if requested by any such Person) confirm such notice in writing, (i) when a prospectus or any prospectus supplement or post-effective amendment has been filed, and, with respect to a registration statement or any post-effective amendment, when the same has become effective under the Securities Act and each applicable state law; (ii) of any request by the SEC or any other federal or state governmental authority for amendments or supplements to a registration statement or related prospectus or for additional information; (iii) of the issuance by the SEC of any stop order suspending the effectiveness of a registration statement or the initiation of any proceedings for that purpose; (iv) if at any time the representations or warranties of OSI contained in any agreement (including any underwriting agreement) contemplated by Section 5(h) below cease to be true and correct in any material respect; (v) of the receipt by OSI of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Registrable Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; (vi) of the happening of any event which makes any statement made in such registration statement or related prospectus or any document incorporated or deemed to be incorporated therein by reference untrue in any E-8 166 material respect or that requires the making of any changes in such registration statement, prospectus or documents so that, in the case of the registration statement, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and that in the case of the prospectus, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, and (vii) of OSI's reasonable determination that a post-effective amendment to a registration statement would be appropriate; (e) use every commercially reasonable effort to obtain the withdrawal of any order suspending the effectiveness of a registration statement, or the lifting of any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction, at the earliest practicable moment; (f) cooperate with the Selling Holders and the managing Underwriter or Underwriters to facilitate the timely preparation and delivery of certificates representing Registrable Securities to be sold, which certificates shall not bear any restrictive legends and shall be in a form eligible for deposit with The Depositary Trust Company; and enable such Registrable Securities to be registered in such names as the managing Underwriter or Underwriters may request prior to any sale of Registrable Securities; (g) use all commercially reasonable efforts to register or qualify such Registrable Securities as promptly as practicable under such other securities or blue sky laws of such jurisdictions as any Selling Holder or managing Underwriter reasonably (in light of the intended plan of distribution) requests and do any and all other acts and things which may be reasonably necessary or advisable to enable such Selling Holder or managing Underwriter to consummate the disposition in such jurisdictions of the Registrable Securities owned by such Selling Holder; provided, however, that OSI will not be required to (i) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this paragraph (g); (ii) subject itself to taxation in any such jurisdiction or (iii) consent to general service of process in any such jurisdiction; (h) enter into customary agreements (including an underwriting agreement in customary form) and take such other actions as are reasonably required in order to expedite or facilitate the disposition of such Registrable Securities; (i) make available for inspection by any Selling Holder of such Registrable Securities, any Underwriter participating in any disposition pursuant to such registration statement and any attorney, accountant or other professional retained by any such Selling Holder or Underwriter (collectively, the "Inspectors"), all financial and other records, pertinent corporate documents and properties of OSI (collectively, the "Records") as shall be reasonably necessary to enable them to exercise their due diligence responsibility, and cause OSI's officers, directors and employees to supply all information reasonably requested by any such Inspectors in connection with such registration statement. Each Selling Holder of such Registrable Securities agrees that information obtained by it as a result of such E-9 167 inspections shall be deemed confidential and shall not be used by it as the basis for any market transactions in the securities of OSI or its Affiliates unless and until such is made generally available to the public. (j) use all commercially reasonable efforts to obtain a comfort letter or comfort letters from OSI's independent public accountants in customary form and covering such matters of the type customarily covered by comfort letters as the Selling Holders of a majority of the shares of Registrable Securities being sold or the managing Underwriter or Underwriters reasonably requests; (k) otherwise use all commercially reasonable efforts to comply with all applicable rules and regulations of the SEC, and make available to its security holders, as soon as reasonably practicable, an earnings statement covering a period of twelve months, which twelve month period shall commence no later than three months after the effective date of the registration statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act; (l) use all commercially reasonable efforts to cause all such Registrable Securities to be listed on each securities exchange on which similar securities issued by OSI are then listed or quoted on any inter-dealer quotation system on which similar securities issued by OSI are then quoted; (m) subject to the provisions of Section 4(c) if any event contemplated by Section 5(d)(vi) above shall occur, as promptly as practicable prepare a supplement or amendment or post-effective amendment to such registration statement or the related prospectus or any document incorporated therein by reference or promptly file any other required document so that, as thereafter delivered to the purchasers of the Registrable Securities, the prospectus will not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading; and (n) cooperate and assist in any filing required to be made with the National Association of Securities Dealers, Inc. and in the performance of any due diligence investigation by any underwriter, including any "qualified independent underwriter," or any Selling Holder. OSI may require each Selling Holder to promptly furnish in writing to OSI such information regarding the distribution of the Registrable Securities as it may from time to time reasonably request and such other information as may be legally required in connection with such registration. Notwithstanding anything herein to the contrary, OSI shall have the right to exclude from any offering the Registrable Securities of any Selling Holder who does not comply with the provisions of the immediately preceding sentence. Each Selling Holder agrees that, upon receipt of any notice from OSI of the happening of any event of the kind described in Section 5(d)(vi) hereof, such Selling Holder will forthwith discontinue disposition of Registrable Securities pursuant to the registration statement covering such E-10 168 Registrable Securities until such Selling Holder's receipt of the copies of the supplemented or amended prospectus contemplated by Section 5(m) hereof, and, if so directed by OSI, such Selling Holder will deliver to OSI all copies, other than permanent file copies, then in such Selling Holder's possession, of the most recent prospectus covering such Registrable Securities at the time of receipt of such notice. In the event OSI shall give such notice, OSI shall extend the period during which such registration statement shall be maintained effective (including the period referred to in Section 5(b) hereof) by the number of days during the period from and including the date of the giving of notice pursuant to Section 5(d)(vi) hereof to the date when OSI shall make available to the Selling Holders of Registrable Securities covered by such registration statement a prospectus supplemented or amended to conform with the requirements of Section 5(m) hereof. SECTION 6 REGISTRATION EXPENSES. Subject to the provisions in Section 2(b) above with respect to a Demand Registration, in connection with any Demand Registration or Piggyback Registration hereunder, OSI shall pay the following registration expenses (the "Registration Expenses"): (a) all registration and filing fees (including, without limitation, with respect to filings to be made with the National Association of Securities Dealers, Inc.), (b) fees and expenses of compliance with securities or blue sky laws (including reasonable fees and disbursements of counsel in connection with blue sky qualifications of the Registrable Securities), (c) printing expenses, (d) internal expenses (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties), (e) the fees and expenses incurred in connection with the listing of the Registrable Securities on an exchange or the quotation of the Registrable Securities on an inter-dealer quotation system, (f) reasonable fees and disbursements of counsel for OSI and customary fees and expenses for independent certified public accountants retained by OSI (including the expenses of any comfort letters requested pursuant to Section 5(j) hereof), (g) the reasonable fees and expenses of any special experts retained by OSI in connection with such registration, (h) reasonable fees and expenses of one counsel reasonably acceptable to OSI selected by the Selling Holders incurred in connection with the registration of such Registrable Securities hereunder and (i) fees and expenses of any "qualified independent underwriter" or other independent appraiser participating in any offering pursuant to the requirements of the National Association of Securities Dealers, Inc. OSI shall not have any obligation to pay any underwriting fees, discounts, or commissions attributable to the sale of Registrable Securities, any capital gains, income or transfer taxes or, except as provided by clause (b), (h) or (i) above, any out-of-pocket expenses of the Holders (or the agents who manage their accounts) or the fees and disbursements of counsel for any Underwriter. SECTION 7 INDEMNIFICATION; CONTRIBUTION. (a) Indemnification by OSI. OSI agrees to indemnify and hold harmless each Selling Holder, each Person, if any, who controls such Selling Holder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and the officers, directors, agents, members, general and limited partners, and employees of each Selling Holder and each such controlling person from and against any and all losses, claims, damages, liabilities, and expenses (including reasonable costs of investigation) arising out of or based upon any untrue statement or alleged untrue statement of a material fact contained in any registration statement or prospectus relating to the Registrable Securities or in any amendment or supplement thereto or in any preliminary prospectus, or arising out E-11 169 of or based upon any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages, liabilities or expenses arise out of, or are based upon, any such untrue statement or omission or allegation thereof based upon information furnished in writing to OSI by such Selling Holder or on such Selling Holder's behalf expressly for use therein. OSI also agrees to indemnify any Underwriters of the Registrable Securities, their officers and directors and each Person who controls such Underwriters on substantially the same basis as that of the indemnification of the Selling Holders provided in this Section 7(a). (b) Indemnification by Holder of Registrable Securities. Each Selling Holder, severally and not jointly, agrees to indemnify and hold harmless OSI, and each Person, if any, who controls OSI within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act and the officers, directors, agents and employees of OSI and each such controlling Person to the same extent as the foregoing indemnity from OSI to such Selling Holder, but only with respect to information furnished in writing by such Selling Holder or on such Selling Holder's behalf expressly for use in any registration statement or prospectus relating to the Registrable Securities. The liability of any Selling Holder under this Section 7(b) shall be limited to the aggregate cash and property received by such Selling Holder pursuant to the sale of Registrable Securities covered by such registration statement or prospectus. (c) Conduct of Indemnification Proceedings. If any action or proceeding (including any governmental investigation) shall be brought or asserted against any Person entitled to indemnification under Section 7(a) or 7(b) above (an "Indemnified Party") in respect of which indemnity may be sought from any party who has agreed to provide such indemnification (an "Indemnifying Party"), the Indemnified Party shall give prompt written notice to the Indemnifying Party and the Indemnifying Party shall assume the defense thereof, including the employment of counsel reasonably satisfactory to such Indemnified Party, and shall assume the payment of all reasonable expenses of such defense. Such Indemnified Party shall have the right to employ separate counsel in any such action or proceeding and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party unless (i) the Indemnifying Party has agreed to pay such fees and expenses or (ii) the Indemnifying Party fails promptly to assume the defense of such action or proceeding or fails to employ counsel reasonably satisfactory to such Indemnified Party or (iii) the named parties to any such action or proceeding (including any impleaded parties) include both such Indemnified Party and Indemnifying Party (or an Affiliate of the Indemnifying Party), and such Indemnified Party shall have been advised by counsel that there is a conflict of interest on the part of counsel employed by the Indemnifying Party to represent such Indemnified Party (in which case, if such Indemnified Party notifies the Indemnifying Party in writing that it elects to employ separate counsel at the expense of the Indemnifying Party, the Indemnifying Party shall not have the right to assume the defense of such action or proceeding on behalf of such Indemnified Party). Notwithstanding the foregoing, the Indemnifying Party shall not, in connection with any one such action or proceeding or separate but substantially similar related actions or proceedings in the same jurisdiction arising out of the same general E-12 170 allegations or circumstances, be liable at any time for the fees and expenses of more than one separate firm of attorneys (together in each case with appropriate local counsel). The Indemnifying Party shall not be liable for any settlement of any such action or proceeding effected without its written consent (which consent will not be unreasonably withheld), but if settled with its written consent, or if there be a final judgment for the plaintiff in any such action of proceeding, the Indemnifying Party shall indemnify and hold harmless such Indemnified Party from and against any loss or liability (to the extent stated above) by reason of such settlement or judgment. The Indemnifying Party shall not consent to entry of any judgment or enter into any settlement that does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release, in form and substance satisfactory to the Indemnified Party, from all liability in respect of such action or proceeding for which such Indemnified Party would be entitled to indemnification hereunder. (d) Contribution. If the indemnification provided for in this Section 7 is unavailable to the Indemnified Parties in respect of any losses, claims, damages, liabilities or judgments referred to herein, then each such Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such losses, claims, damages, liabilities and judgments as between OSI on the one hand and each Selling Holder on the other, in such proportion as is appropriate to reflect the relative fault of OSI and of each Selling Holder in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or judgments, as well as any other relevant equitable considerations. The relative fault of OSI on the one hand and of each Selling Holder on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by such party, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. OSI and the Selling Holders agree that it would not be just and equitable if contribution pursuant to this Section 7(d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the first two sentences of this Section 7(d). The amount paid or payable by an Indemnified Party as a result of the losses, claims, damages, liabilities or judgments referred to in Sections 7(a) and (b) hereof shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 7(d), no Selling Holder shall be required to contribute any amount in excess of the amount by which the total price at which the Registrable Securities of such Selling Holder were offered to the public exceeds the amount of any damages which such Selling Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. SECTION 8 PARTICIPATION IN UNDERWRITTEN REGISTRATIONS. No Holder may participate in any underwritten registration hereunder unless such Holder (a) agrees to sell such Holder's E-13 171 Registrable Securities on the basis provided in any underwriting arrangements approved by the Person entitled hereunder to approve such arrangements, and (b) timely completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements, custody agreements and other documents reasonably required under the terms of such underwriting arrangements and this Agreement. SECTION 9 MISCELLANEOUS. 9.1 Rule 144. OSI covenants that, upon any registration statement covering Company securities becoming effective, it will file the reports required to be filed by it under the Exchange Act and the rules and regulations adopted by the Commission thereunder, and it will take such other action as any Holder of Registrable Securities may reasonably request, all to the extent required from time to time to enable such Holder to sell Registrable Securities without registration under the 1933 Act within the limitation of the exemptions provided by (a) Rule 144 under the 1933 Act, as such Rule may be amended from time to time, or (b) any similar rule or regulation hereafter adopted by the Commission. Upon the request of any Holder of Registrable Securities, OSI will deliver to such Holder a written statement as to whether it has complied with such requirements. 9.2 Issuance of New Certificates. Each Holder who ceases to be a Holder may thereafter surrender any certificate or certificates of OSI Common Stock bearing legends restricting the transferability thereof and shall be entitled, upon such surrender, to receive in exchange therefor a certificate or certificates, free of such restrictive legends, representing the same number of shares of OSI Common Stock; provided, however, that prior to the issuance of such unrestricted shares of OSI Common Stock, OSI may require an opinion of its counsel, at its expense, in customary form and reasonably satisfactory to OSI to the effect that the issuance of such unrestricted shares is permitted under applicable federal and state securities laws. If any such certificate for OSI Common Stock is to be issued in a name other than that in which the surrendered certificate is registered, it shall be a condition of such exchange that the certificate so surrendered shall be properly endorsed or otherwise in proper form for transfer and that the person requesting such exchange shall have paid any transfer and other taxes required by reason of such issuance of certificates of OSI Common Stock in a name other than that of the registered holder of the certificate surrendered, or shall have established to the satisfaction of OSI and its transfer agent that such tax has been paid or is not applicable. 9.3 Waiver and Amendment. Any provision of this Agreement may be waived at any time by the party that is, or whose stockholders or partners are, entitled to the benefits thereof. This Agreement may not be amended or supplemented at any time, except by an instrument in writing signed on behalf of the Holders of 50% or more of the Registrable Securities. 9.4 Assignment. The registration rights of Holders under this Agreement may be assigned and transferred to any transferee acquiring Registrable Securities, other than in a public offering pursuant to a registration statement or pursuant to Rule 144; provided, however, that OSI is given written notice by the Holder at the time of such transfer stating the name and address of the transferee and identifying the Registrable Securities with respect to which the rights under this Agreement are being assigned and the transferee agrees to be bound by the terms and conditions hereof and agrees to execute and deliver to OSI an acknowledgement and agreement to such effect. E-14 172 This Agreement shall also be binding upon and enforceable by the heirs, executors, or other personal representatives of the Holders and the successors and assigns of OSI. 9.5 Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given when delivered if delivered in person, by cable, telegram, telex, or telecopy and shall be deemed to have been duly given three business days after deposit with a United States post office if delivered by registered or certified mail (postage prepaid, return receipt requested) to the respective parties as follows: if to OSI: Oil States International, Inc.

This Agreement, including the exhibits hereto and the documents, information supplied in writing, and instruments referred to herein, constitute the entire agreement and supersedes all other prior agreements, and understandings, both oral and written, among the parties or any of them, with respect to the subject matter hereof. Except as set forth in Section 3(c) hereof with respect to holders of PTI Exchangeable Shares, this Agreement shall be binding upon and inure solely to the benefit of the parties hereto, and nothing E-16 174 in this Agreement and the documents, information supplied in writing, and instruments referred to herein, express or implied, is intended to confer upon any other person any rights or remedies of any nature whatsoever under or by reason of this Agreement. For greater certainty, Section 3(c) hereof, and the application of this Agreement contemplated thereby, shall inure to the benefit of, and shall be enforceable against the parties hereto by, the holders of PTI Exchangeable Shares. 9.11 Termination. The provisions of Sections 2, 3, 4, 5 and 6 shall terminate and be of no further force or effect on or after the tenth anniversary of the date hereof.

UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS TO THE PARTICIPATING SHAREHOLDERS SHAREHOLDERS THAT ARE UNITED STATES HOLDERS The following is a summary of certain United States federal income tax considerations generally applicable to the Participating Shareholders that are "United States persons," as defined for United States federal income tax purposes, and that currently hold shares of HWC, Sooner or PTI as capital assets ("United States Holders"), upon entering into the proposed transactions as detailed in the Combination Agreement and Form S-1 (collectively the "Proposed Arrangement"), including the receipt and ownership of OSI Common Stock. For United States federal income tax purposes, "United States persons" are United States citizens or residents, corporations or partnerships organized under the laws of the United States or any state thereof, estates subject to United States federal income tax on their income regardless of source and trusts subject to the primary supervision of a court within the United States and control of a United States fiduciary as described in Section 7701(a)(30) of the U.S. Internal Revenue Code of 1986, as amended (the "Code"). This summary is based on United States federal income tax law in effect as of the date hereof. Although certain statutory and administrative authorities exist which address certain of the United States federal income tax consequences related to the issuance and receipt of equity interests in the common stock of a corporation, the conclusions expressed herein are subject to interpretation and are not absolutely certain. No advance income tax ruling has been sought or obtained from the United States Internal Revenue Service ("IRS") regarding the United States federal income tax consequences of any of the transactions described herein. This summary does not address aspects of United States taxation other than United States federal income taxation, nor does it address all aspects of United States federal income taxation that may be applicable to particular United States Holders, including, without limitation, holders of stock options and holders of common shares acquired as a result of the exercise of employee stock options. In addition, this summary does not address the United States state or local tax consequences or the foreign tax consequences of the Proposed Arrangement. UNITED STATES HOLDERS ARE URGED TO CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE UNITED STATES FEDERAL, STATE AND LOCAL TAX CONSEQUENCES AND THE FOREIGN TAX CONSEQUENCES OF THE PROPOSED ARRANGEMENT. 180 Characterization of the Proposed Arrangement for United States Federal Income Tax Purposes. The management of OSI anticipates receiving a tax opinion from Ernst & Young LLP upon the satisfactory completion of the necessary information requests, representations, and other document requests. This opinion would provide that, based upon current statutory and administrative authorities, the Proposed Arrangement should qualify as a tax free transfer to a controlled corporation within the meaning of Section 351(a) of the Code. However, there can be no assurance that the IRS would not challenge the status of the Proposed Arrangement as a transfer to a controlled corporation or that, if challenged, a court would not agree with the IRS. The tax opinion is subject to certain customary assumptions, qualifications and similar matters and is limited solely to certain United States federal income tax consequences of the Proposed Arrangement. The following substantially represents the anticipated federal income tax consequences of the Proposed Arrangement that OSI anticipates receiving in the tax opinion from Ernst & Young LLP. Receipt of OSI common shares. Assuming the Proposed Arrangement qualifies under Section 351(a) of the Code, the following federal income tax consequences should occur: (i) except as provided below, a United States Holder of HWC, Sooner or PTI shares who solely receives OSI common shares pursuant to the Proposed Arrangement should not recognize any gain or loss with respect to the receipt of such shares; (ii) except as provided below, the aggregate basis of the OSI common shares received pursuant to the Proposed Arrangement by a United States Holder should equal such holder's aggregate tax basis in the shares of HWC, Sooner or PTI shares exchanged pursuant to the Proposed Arrangement reduced by the tax basis allocated to fractional share interests for which cash is received; (iii) the holding period for federal income tax purposes of the OSI common shares received by a United States Holder of HWC, Sooner or PTI shares pursuant to the Proposed Arrangement should include the holding period of the HWC, Sooner or PTI shares exchanged therefor; and (iv) cash payments in lieu of a fractional OSI common share should be treated as a taxable exchange of cash in full payment for the fractional share. 181 EXHIBIT G SUMMARY OF TAX OPINION OF ERNST & YOUNG LLP (PTI) THIS DRAFT IS FURNISHED SOLELY TO ILLUSTRATE CERTAIN OF THE EXPECTED TAX CONSIDERATIONS THAT WILL BE CONTAINED IN THE FINAL OPINION ASSUMING A SATISFACTORY COMPLETION OF CERTAIN DUE DILIGENCE PROCEDURES AND REPRESENTATIONS FROM MANAGEMENT. The matters discussed below will, along with additional matters, be set out more fully in the Income Tax Considerations section of the Management Information Circular. The following is a brief summary of some of the Canadian federal income tax consequences to PTI Group, Inc. ("PTI") and its shareholders of the Combination Agreement and the Arrangement. It is not intended to be, and should not be construed to be, legal, business or tax advice to either PTI or any particular shareholder of PTI. This summary assumes that PTI shareholders hold their shares of PTI as capital property for purposes of the Canadian Income Tax Act (the "Act"). TAX CONSEQUENCES TO PTI The Combination Agreement and the Arrangement may result in an acquisition of control of PTI for Canadian income tax purposes. There are a number of tax consequences that arise if there is an acquisition of control including a deemed year end for tax purposes with all of the requisite filing requirements; realization of accrued losses; expiration of capital losses and property losses; and restrictions on the future utilization of non-capital losses. PTI will also have a deemed year end for tax purposes on the amalgamation of PTI and PTI Amalco. There should be no other significant tax consequences to PTI as a result of the amalgamation. As discussed below, on a redemption (including a retraction) of an Exchangeable Share by PTI Holdco, the shareholder will be deemed to have received and PTI Holdco will be deemed to have paid a dividend equal to the amount, if any, by which the redemption proceeds (the fair market value at that time of the Oil States International, Inc. ("OSI") Common Stock received by the shareholder from PTI Holdco on the redemption) exceed the paid-up capital (for purposes of the Act) of the Exchangeable Share at the time the share is redeemed. PTI Holdco will be required to pay annually a tax under Part VI.1 of the Act equal to 66 2/3% of the amount, if any, by which the total of all taxable dividends paid or deemed to have been paid on the Exchangeable Shares for the year exceeds $500,000. PTI Holdco will also be entitled to deduct, in computing taxable income, an amount equal to 9/4 of the Part VI.1 tax it is required to pay for the year. If certain conditions are met, this Part VI.1 tax and corresponding deduction may be transferred to a related Canadian corporation. 182 PTI SHAREHOLDERS RESIDENT IN CANADA On the amalgamation of PTI and PTI Amalco, a PTI shareholder will be deemed to have disposed of PTI common shares owned by the PTI common shareholder for proceeds equal to the adjusted cost base of the PTI common shares to that shareholder immediately before the amalgamation; as a result, no capital gain or capital loss will generally arise for a PTI shareholder on the amalgamation. The PTI shareholder will be deemed to have acquired the shares of New PTI Group, Inc. ("New PTI") on the amalgamation at a cost equal to the proceeds of disposition of the PTI common shares referred to above. The increase in legal stated capital of the Class B shares of New PTI will result in a deemed dividend to the Class B shareholders. The tax implications of that deemed dividend are not discussed in this summary. This increase in legal stated capital of the Class B shares will not have any adverse income tax implications to the other shareholders of New PTI or to New PTI itself. The increase in legal stated capital of the Class C shares of New PTI will result in a deemed dividend to the Class C shareholders. The tax implications of that deemed dividend are not discussed in this summary. This increase in legal stated capital of the Class C shares will not have any adverse income tax implications to the other shareholders of New PTI or to New PTI itself. On the transfer of the shares of New PTI by the New PTI shareholder to PTI Holdco, the New PTI shareholder and PTI Holdco will file the appropriate joint elections pursuant to the provisions of section 85(1) of the Act electing an amount (the "Elected Amount") selected by the New PTI shareholder within the limits provided for under the Act. A New PTI shareholder who receives Exchangeable Shares of PTI Holdco and ancillary rights and benefits on the transfer of the New PTI shares to PTI Holdco will not realize a capital gain for Canadian income tax purposes on the transfer provided that the shareholder files the joint election with PTI Holdco with an Elected Amount equal to the adjusted cost base to the shareholder of the shareholder's New PTI shares and such adjusted cost base exceeds the sum of: (i) any cash received in respect of a fractional Exchangeable Share; and (ii) the fair market value of the ancillary rights and benefits received by such shareholder in connection with the exchange. A New PTI shareholder will realize a capital gain to the extent that such sum, net of any reasonable costs of disposition, exceeds the adjusted cost base of the New PTI shares to the shareholder. Certain shareholders may realize a dividend rather than a capital gain. A New PTI shareholder will be required to determine the fair market value of the ancillary rights and benefits received. Any determination of value is not binding on the Canada Customs and Revenue Agency ("CCRA"). It is possible that the CCRA could take the position that the ancillary rights and benefits have a fair market value in excess of a nominal amount. A shareholder who selects an Elected Amount greater than the adjusted cost base of the New PTI shares will realized a capital gain to the extent that elected amount, net of any reasonable costs of disposition exceeds the adjusted cost base. On the redemption (including a retraction) of an Exchangeable Share by PTI Holdco, the shareholder of the Exchangeable Share will be deemed to have received a dividend from PTI Holdco equal to 183 the amount, if any, by which the redemption proceeds (the fair market value at that time of the OSI Common Stock received by the shareholder from PTI Holdco on the redemption) exceed the paid-up capital (for purposes of the Act) of the Exchangeable Share at the time the share is redeemed. The shareholder will also be considered to have disposed of the Exchangeable Share for proceeds of disposition equal to the redemption proceeds less the amount of such deemed dividend. On the exchange of an Exchangeable Share by the shareholder thereof with OSI ULC for OSI Common Stock, the shareholder will in general realize a capital gain (or capital loss) to the extent the proceeds of disposition of the Exchangeable Share, net of any reasonable costs of disposition, exceed (or are less than) the adjusted cost base to the holder of the Exchangeable Share. For these purposes, the proceeds of disposition will be the fair market value, at the time of the exchange, of the OSI Common Stock received on the exchange. Because of the existence of the Redemption and Retraction Call Rights, a PTI Exchangeable Shareholder cannot control whether such shareholder will receive the OSI Common Stock by way of a redemption of the Exchangeable Shares or by way of a purchase of the Exchangeable Shares. As described above, the income tax consequences of a redemption differ from those of a purchase. The cost of the OSI Common Stock received on the retraction, redemption or exchange of Exchangeable Shares will be equal to the fair market value of such OSI Common Stock at the time of such event, and must be averaged with the adjusted cost base of any other OSI Common Stock held at that time by the holder for the purposes of determining the adjusted cost base of all OSI Common Stock held by the holder. On June 22, 2000, the Department of Finance released draft amendments to the Act regarding the taxation of "participating interests" of Canadian taxpayers in "foreign investment entities". The intention of the legislation is to prevent Canadian taxpayers from avoiding Canadian income tax by transferring funds to offshore accounts. Under these provisions, both a PTI Holdco Exchangeable Share and an OSI common share will be considered to be a "participating interest" in OSI. If OSI is determined to be a "foreign investment entity" there would be negative tax consequences to Canadian shareholders holding such interests. Basically, a "foreign investment entity" is a non-resident entity the "investment property" of which represents at least half of its assets. It is anticipated that OSI will not be a "foreign investment entity" on the basis that half of its assets will not be investment property and, therefore, these draft provisions should not apply. PTI OPTIONHOLDERS There should be no negative income tax consequences to a PTI Optionholder on the exchange of the options to acquire PTI Common shares for options to acquire OSI Common Shares.. PTI SHAREHOLDERS NOT RESIDENT IN CANADA The transfer by the non-resident shareholders of PTI of their shares of PTI to OSI in exchange for common stock of OSI is a disposition of "taxable Canadian property" ("TCP") for Canadian income tax purposes. Any gain arising on the disposition by a non-resident of TCP is taxable in Canada, subject to the terms of any bi-lateral income tax treaty that Canada has entered into with the country 184 of which the disposing shareholder is resident. In particular, pursuant to the terms of the Canada - US Income Tax Convention (the "Treaty"), Canada cannot tax a gain realized by a shareholder of PTI who is a resident of the US for purposes of the Treaty. Any Canadian non-resident shareholder who is not a resident of the US for purposes of the Treaty, or of a jurisdiction with a similar treaty, will be taxable on the gain arising on the transfer. Where a partnership is a shareholder, the Canadian tax rules will generally require that these rules be applied separately to each partner of the partnership with respect to their proportionate share of the gain. Where a partnership is itself a partner in a partnership, it will be necessary to look through that partnership as well. Regardless of whether any particular non-resident shareholder of PTI is subject to Canadian income tax on the gain, such non-resident shareholder must notify CCRA of the disposition and obtain a clearance certificate (a "Section 116 certificate") from CCRA. In the event the transferor does not obtain a Section 116 certificate, OSI as the purchaser, is required to withhold an amount equal to 33 1/3% of the cost to OSI of the shares of PTI and remit this amount to the CCRA. For these purposes, the cost of the shares of PTI will be the aggregate fair market value, at the time of the transfer, of the OSI Common Stock delivered to the PTI shareholders in exchange for their shares of PTI. 185 EXHIBIT H FORM OF OMNIBUS CONSENT, WAIVER AND AGREEMENT OF SHAREHOLDERS OF HWC 186 EXHIBIT H OMNIBUS CONSENT, WAIVER AND INVESTMENT AGREEMENT OF THE SHAREHOLDERS OF HWC ENERGY SERVICES INC.
