TRANSACTION SYSTEMS ARCHITECTS, INC. NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS 1. Consolidated Financial Statements Transaction Systems Architects, Inc. ("TSA" or the "Company"), a Delaware corporation, develops, markets, installs and supports a broad line of software products and services primarily focused on facilitating electronic payments and electronic commerce. In addition to its own products, the Company distributes or acts as a sales agent for software developed by third parties. The products and services are used principally by financial institutions, retailers and e-payment processors, both in domestic and international markets. The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated. The condensed consolidated financial statements at March 31, 2001, and for the three and six months ended March 31, 2001 and 2000, are unaudited and reflect all adjustments (consisting only of normal recurring adjustments) which are, in the opinion of management, necessary for a fair presentation of the financial position and operating results for the interim periods. The condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto, together with management's discussion and analysis of financial condition and results of operations, contained in the Company's Annual Report on Form 10-K for the fiscal year ended September 30, 2000. The results of operations for the three and six months ended March 31, 2001 are not necessarily indicative of the results for the entire fiscal year ending September 30, 2001. 2. Revenue Recognition The Company generates revenues from licensing software and providing postcontract customer support (maintenance or "PCS") and other professional services. The Company uses written contracts to document the elements and obligations of arrangements with its customers. Arrangements that include the licensing of software typically include PCS, and at times, include other professional services. PCS includes the right to unspecified upgrades on a when-and-if-available basis and ongoing technical support. The other professional services may include training, installation or consulting. The Company also performs services for customers under arrangements that do not include the licensing of software. Revenues under multiple-element arrangements, which may include several software products or services sold together, are allocated to each element based upon the residual method in accordance with American Institute of Certified Public Accountants Statement of Position ("SOP") 98-9, "Software Revenue Recognition, With Respect to Certain Arrangements." Under the residual method, the fair value of the undelivered elements is deferred and subsequently recognized. The Company has established sufficient vendor specific objective evidence of fair value for PCS and other professional services based upon the price charged when these elements are sold separately. Accordingly, software license fees revenues are recognized under the residual method in arrangements in which the software is licensed with PCS and/or other professional services, and the undelivered elements of the arrangement are not essential to the functionality of the delivered software. The Company recognizes software license fees upon execution of the signed contract, delivery of the software to the customer, determination that the software license fees are fixed or determinable, and determination that the collection of the software license fees is probable. The software license is typically for a term of up to 60 months and does not include a right of return. The term for the PCS element of a software arrangement is typically for a period shorter than the term of the software license, and can be renewed by the customer over the remaining term of the software license. PCS or maintenance revenues are recognized ratably over the term of the arrangement on a straight-line basis. The other professional services element of a software arrangement is typically accounted for separately as the services are performed for time-and-materials contracts or on a percentage-of-completion basis for fixed-price contracts. In those instances where the services are essential to the functionality of any other element of the arrangement, contract accounting is applied to both the software and services elements of the arrangement. The Company follows two methods for pricing its software licenses. Under the first method, the software license is priced based upon the number of transactions processed by the customer ("transaction-based pricing"). Under transaction-based pricing, the customer is allowed to process a contractually predetermined maximum volume of transactions per month for a specified period of time. Once the customer's transaction volume exceeds this maximum volume level, the customer is required to pay additional license fees for each incremental volume level. Under the second method, the software license is priced on a per copy basis and tiered to recognize different performance levels of the customer's processing hardware ("designated-equipment-group pricing"). Under designated-equipment-group pricing, the customer pays a license fee for each copy of the software for a specified period of time. Licensees are typically given two payment options. Under the first payment option, the licensee can pay a combination of an Initial License Fee ("ILF"), where the licensee pays a portion of the total software license fees at the beginning of the software license term, and a Monthly License Fee ("MLF"), where the licensee pays the remaining portion of the software license fees over the software license term. In certain arrangements, the customer is contractually committed to making MLF payments for a minimum number of months. If the customer decides to terminate the arrangement prior to paying the minimum MLF payments, the remaining minimum MLF payments become due and payable. Under the second payment option, the Company offers a Paid-Up-Front ("PUF") payment option, whereby the total software license fees are due at the beginning of the software license term. Under either payment option, the Company is not obligated to refund any payments received from the customer. In the combination ILF and MLF payment option, the Company recognizes the ILF portion of the software license fees upon delivery of the software, assuming all other revenue recognition criteria were met. In the PUF payment option, the Company recognizes the total software license fees upon delivery of the software, assuming all other revenue recognition criteria were met. In addition to SOP 98-9, the Company accounts for its software arrangements in accordance with SOP 97-2, "Software Revenue Recognition." The primary software revenue recognition criteria outlined in SOP 97-2 include: evidence of an arrangement; delivery; fixed or determinable fees; and collectibility. SOP 97-2 specifies that extended payment terms in a software licensing arrangement may indicate that the software license fees are not deemed to be fixed or determinable. In addition, if payment of a significant portion of the software license fees is not due until more than twelve months after delivery, the software license fees should be presumed not to be fixed or determinable, and thus should be recognized as the payments become due. However, SOP 97-2 specifies that if the Company has a standard business practice of using extended payment terms in software licensing arrangements and has a history of successfully collecting the software license fees under the original terms of the software licensing arrangement without making concessions, the Company can overcome the presumption that the software license fees are not fixed or determinable. If the presumption is overcome, the Company should recognize the software license fees when all other SOP 97-2 revenue recognition criteria are met. The Company has concluded that for certain software arrangements where the customer is contractually committed to make MLF payments that extend beyond twelve months, the "fixed or determinable" presumption has been overcome and software license fees revenue should be recognized upon meeting the other SOP 97-2 revenue recognition criteria. In making this determination, the Company considered the characteristics of the software product, the customer purchasing the software, the similarity of the economics of the software arrangements with previous software arrangements and the actual history of successfully collecting under the original terms without providing concessions. The software license fees recognized under these arrangements are referred to as "Recognized-Up-Front MLFs." The present value of Recognized-Up-Front MLFs, net of third party royalties, recognized during the three months ended March 31, 2001 and 2000 totaled approximately $2.8 million and $5.4 million, respectively. The present value of Recognized-Up-Front MLFs, net of third party royalties, recognized during the six months ended March 31, 2001 and 2000 totaled approximately $11.9 million and $10.5 million, respectively. The discount rates used to determine the present value of these software license fees, representing the Company's incremental borrowing rates, ranged from 9.50% to 11.00% during the six months ended March 31, 2001, and from 10.25% to 11.00% during the six months ended March 31, 2000. Recognized-Up-Front MLFs that have been recognized in software license fees revenues by the Company, but not yet billed, are reflected in accrued receivables in the accompanying condensed consolidated balance sheets. 3. Non-Recurring Items The Company continually evaluates its investment holdings and long-lived assets for evidence of impairment. During the three months ended December 31, 2000, after considering current market conditions for technology companies and specific information regarding those companies in which the Company has an ownership interest, the Company determined that the declines in market value for certain of its investment holdings were "other than temporary" and a charge to earnings for the declines in market value was required. Therefore, the Company recorded a non-cash charge of $12.4 million in the three months ended December 31, 2000. In addition, due to unfavorable market conditions in the fourth quarter of fiscal 2000, the Company postponed its planned initial public offering ("IPO") of its wholly-owned subsidiary, Insession Technologies, Inc. Due to the time period which had elapsed without proceeding with this transaction and continuing uncertainty in market conditions, the Company expensed costs associated with the planned IPO totaling $1.9 million in the three months ended December 31, 2000. 4. Acquisition In January 2001, the Company acquired all of the outstanding securities of MessagingDirect Ltd. ("MDL"). MDL provides software applications to facilitate the secure delivery and e-processing of electronic statements and bills. Shareholders of MDL received 3,357,351 shares of Class A Common Stock (or Exchangeable Shares of TSA Exchangeco Limited which can be converted on a one-for-one basis for shares of TSA Class A Common Stock or options to purchase shares of TSA Class A Common Stock) with a fair market value at the time of purchase of approximately $49.5 million. The share exchange was accounted for using the purchase method of accounting. An independent valuation of MDL was performed and used as an aid in determining the fair market value of each identifiable intangible asset. Accordingly, the excess purchase price over the estimated fair value of each identifiable tangible and intangible asset acquired was allocated to goodwill, which is being amortized using the straight-line method over five years. Preliminarily, approximately $38.3 million of the purchase price was allocated to goodwill and $11.8 million to software. 5. Common Stock and Earnings Per Share Earnings per share ("EPS") has been computed in accordance with SFAS No. 128, "Earnings Per Share." Basic EPS is calculated by dividing net income available to common stockholders (the numerator) by the weighted average number of common shares outstanding during the period (the denominator). Diluted EPS is computed by dividing net income available to common stockholders, adjusted for the effect of any outstanding dilutive securities (the numerator), by the weighted average number of common shares outstanding, adjusted for the dilutive effect of outstanding dilutive securities (the denominator). For the three and six months ended March 31, 2001, basic and diluted EPS are the same, as any outstanding dilutive securities were antidilutive due to the net loss in both periods. If the Company had reflected net income for the three and six months ended March 31, 2001, weighted average shares from stock options of 3,867,881 and 3,869,482, respectively, would have been excluded from the computation of diluted EPS because the exercise prices of the stock options were greater than the average market price of the Company's common shares. The differences between the basic and diluted EPS denominators for the three and six months ended March 31, 2000, which amounted to approximately 465,000 and 491,000 shares, respectively, were due to the dilutive effect of the Company's outstanding stock options using the treasury stock method. For the three and six months ended March 31, 2000, weighted average shares from stock options of 1,366,291 and 1,349,679, respectively, have been excluded from the computation of diluted EPS because the exercise prices of the stock options were greater than the average market price of the Company's common shares. Exchangeable Shares and options received by shareholders of MDL (see Note 4) that have not yet been converted into TSA Class A Common Stock are included in Class A Common Stock for presentation purposes on the March 31, 2001 condensed consolidated balance sheet, and are included in common shares outstanding for EPS computations for the three and six months ended March 31, 2001. 6. Comprehensive Income The Company's components of other comprehensive income were as follows (in thousands): Three Months Ended December 31, Six Months Ended March 31, ------------------------------ ------------------------------ 2001 2000 2001 2000 -------------- -------------- -------------- -------------- Net income (loss) $ (3,604) $ 1,551 $ (17,956) $ 168 Other comprehensive income (loss): Foreign currency translation adjustments (5,112) 111 (4,573) (1,012) Unrealized investment holding gain, net of reclassification adjustment of $8,052 in the six months ended March 31, 2001 842 6,080 2,645 10,767 -------------- -------------- -------------- -------------- Comprehensive income (loss) $ (7,874) $ 7,742 $ (19,884) $ 9,923 ============== ============== ============== ============== The Company's components of accumulated other comprehensive income at each balance sheet date were as follows (in thousands): Foreign Unrealized Accumulated Currency Investment Other Translation Holding Comprehensive Adjustments Gain (Loss) Loss -------------- ------------- -------------- Balance, September 30, 2000 $ (4,723) $ (5,803) $ (10,526) Fiscal 2001 year-to-date activity (4,573) (5,407) (9,980) Reclassification adjustment for loss included in net income (loss) - 8,052 8,052 -------------- ------------- -------------- Balance, March 31, 2001 $ (9,296) $ (3,158) $ (12,454) ============== ============= ============== 7. Line-of-Credit Facilities As of March 31, 2001, the Company has a $25.0 million bank line-of-credit with a large United States bank. This line is secured by certain trade receivables of TSA. Among other restrictions, the Company must maintain a minimum accounts receivable balance, minimum tangible net worth and minimum working capital levels at each reporting date. As of March 31, 2001, these minimum amounts to be maintained were $35.0 million of billed receivables less than 90 days past due, $147.0 million of tangible net worth and $50.0 million of working capital. After obtaining a waiver from the U.S. bank due to non-compliance with the minimum tangible net worth covenant, the Company is in compliance with all debt covenants as of March 31, 2001. The Company also has a line-of-credit with a large foreign bank in the amount of 3.0 million British Pounds, which translates to approximately $4.2 million. The foreign line requires the Company to maintain minimum tangible net worth within the Company's wholly-owned subsidiary, ACI Worldwide (EMEA) Ltd. Interest on the U.S. line-of-credit accrues at an annual rate equal to either the bank's "base rate" less .75% or the LIBOR rate plus 1.75% and is payable at the end of each month. Interest on the foreign line-of-credit accrues at an annual rate of 1% above the bank's "base rate." During the three and six months ended March 31, 2001, the Company recorded interest expense of $0.5 million and $1.0 million, respectively, related to the two line-of-credit facilities. The carrying amounts of the Company's line-of-credit facilities approximate fair value due to their variable interest rates. Current borrowings outstanding as of March 31, 2001 totaled approximately $21.2 million. The foreign bank line-of-credit expires on August 9, 2001. Subsequent to March 31, 2001, the U.S. bank reduced the amount of the line-of-credit from $25.0 million to $15.0 million and extended the line-of-credit expiration date from May 31, 2001 to June 30, 2001. 8. Segment Information In fiscal 2000, the Company reorganized its business into four business units or segments: Consumer e-Payments, Electronic Business Infrastructure, Corporate Banking e-Payments and Health Payment Systems. Prior period segment information has been restated to reflect these reorganizations. The Company's chief operating decision makers review business unit financial information, presented on a consolidated basis, accompanied by disaggregated information about revenues and operating income by business unit. The Company does not track assets by business unit. The Company plans to direct the majority of its focus on the Consumer e-Payments and Electronic Business Infrastructure business units. The Company recently discontinued pursuing strategic alternatives for the Electronic Business Infrastructure business unit since the value of the products and services it offers exceeds current technology company market valuations. The Company is considering various alternatives for the Corporate Banking e-Payments and Health Payments Systems business units, including possible sales, spin-offs, strategic alliances, partnerships, third-party investors and initial public offerings. Consumer e-Payments products represent the Company's largest product line and include its most mature and well-established applications which are used primarily by financial institutions, retailers and e-payment processors. Its products are used to route and process transactions for automated teller machine networks; process transactions from traditional point of sale devices, wireless devices and the Internet; handle PC and phone banking transactions; control fraud and money laundering; process electronic benefit transfer transactions; authorize checks; establish frequent shopper programs; automate settlement, card management and claims processing; and issue and manage multi-functional applications on smart cards. Electronic Business Infrastructure products facilitate communication, data movement, monitoring of systems and business process automation across computing systems, involving mainframes, distributed computing networks and the Internet. Corporate Banking e-Payments products offer high-value payments processing, bulk/recurring payments processing, wire room processing, global messaging, integration payments management and continuous link settlement processing. Health Payment Systems products allow large corporations and health-care payment processors to automate claims eligibility determination, claims capture and claims payments.

Accounting Pronouncements Issued But Not Yet Effective In December 1999, the Securities and Exchange Commission (the "SEC") released Staff Accounting Bulletin ("SAB") No. 101, "Revenue Recognition in Financial Statements," which provides guidance on the recognition, presentation and disclosure of revenue in financial statements filed with the SEC. SAB No. 101 requires, among other things, that license and other up-front fees be recognized over the term of the agreement, unless the fees are in exchange for products delivered or services performed that represent the culmination of a separate earnings process. The Company is required to be in conformity with the provisions of SAB No. 101 no later than the fourth quarter of fiscal 2001. The Company is currently reviewing SAB No. 101 and has not determined the impact of its adoption on the Company's financial position or results of operations. In September 2000, the Financial Accounting Standards Board issued SFAS No. 140, "Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities." SFAS No. 140, which replaced SFAS No. 125, "Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities," revises the standards for accounting for securitizations and other transfers of financial assets and collateral and requires certain disclosures, but carries over most of SFAS No. 125's provisions without reconsideration. SFAS No. 140 is effective for transfers and servicing of financial assets and extinguishments of liabilities occurring after March 31, 2001. The Company currently conforms to the requirements of SFAS No. 125 and the adoption of SFAS No. 140 is not expected to have a material impact on the Company's financial position or results of operations.

TRANSACTION SYSTEMS ARCHITECTS, INC. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS Overview The Company develops, markets, installs and supports a broad line of software products and services primarily focused on facilitating electronic payments and electronic commerce. In addition to its own products, TSA distributes software developed by third parties. The products and services are used principally by financial institutions, retailers and e-payment processors, both in domestic and international markets. Business Segments The Company's products and services are organized into four business units - - Consumer e-Payments, Electronic Business Infrastructure, Corporate Banking e-Payments and Health Payment Systems. The Company plans to direct the majority of its focus on the Consumer e-Payments and Electronic Business Infrastructure business units. Products in the Consumer e-Payments business unit represent the Company's largest product line and include its most mature and well-established applications. Products and services offered by this business unit, except community banking products, are marketed and supported through ACI Worldwide Inc ("ACI"), a wholly-owned subsidiary of the Company. ACI sells and supports the products and services through three distribution networks: the Americas, Europe/Middle East/Africa ("EMEA") and Asia/Pacific. Each distribution network primarily has its own sales force and supplements this with reseller and/or distributor networks. The community banking products are marketed and supported by Regency Systems, Inc., a wholly-owned subsidiary of the Company. Products and services offered by the other three business units are marketed and supported primarily through their own sales and support organizations. The following table sets forth total revenues and operating income (loss) for the Company's four business unit segments for the periods indicated (in thousands): Three Months Ended March 31, Six Months Ended March 31, ------------------------------------ ------------------------------------ 2001 2000 2001 2000 ---------------- ---------------- ---------------- ---------------- Revenues: Consumer e-Payments $ 56,776 $ 53,629 $ 114,328 $ 101,345 Electronic Business Infrastructure 10,860 11,290 20,144 22,166 Corporate Banking e-Payments 7,650 9,609 14,258 17,250 Health Payment Systems 1,206 861 2,398 1,745 ---------------- ---------------- ---------------- ---------------- $ 76,492 $ 75,389 $ 151,128 $ 142,506 ================ ================ ================ ================ Operating loss: Consumer e-Payments $ 1,328 $ (1,617) $ 2,224 $ (6,069) Electronic Business Infrastructure (353) 2,428 (1,110) 4,212 Corporate Banking e-Payments (1,737) 1,206 (4,634) 498 Health Payment Systems (422) (65) (1,588) (25) ---------------- ---------------- ---------------- ---------------- Operating loss $ (1,184) $ 1,952 $ (5,108) $ (1,384) ================ ================ ================ ================ Backlog The following table sets forth the Company's recurring and non-recurring revenue backlog, by business unit, at each balance sheet date (in thousands): Recurring Revenue Non-recurring Revenue Backlog Backlog ------------------------------------ ------------------------------------ March 31, Sept. 30, March 31, Sept. 30, 2001 2000 2001 2000 ---------------- ---------------- ---------------- ---------------- Consumer e-Payments $ 95,800 $ 101,100 $ 37,100 $ 39,100 Electronic Business Infrastructure 17,200 19,200 3,800 2,100 Corporate Banking e-Payments 17,000 16,100 12,500 12,900 Health Payment Systems 1,700 2,800 2,000 2,300 ---------------- ---------------- ---------------- ---------------- $ 131,700 $ 139,200 $ 55,400 $ 56,400 ================ ================ ================ ================ The Company defines recurring revenue backlog to be all monthly license fees, maintenance fees and facilities management fees specified in executed contracts to the extent that the Company contemplates recognition of the related revenue within one year. The Company includes in its non-recurring revenue backlog all fees (other than recurring) specified in executed contracts to the extent that the Company contemplates recognition of the related revenue within one year. There can be no assurance that contracts included in recurring or non-recurring revenue backlog will actually generate the specified revenues or that the actual revenues will be generated within the one-year period.

Total revenues for the second quarter of fiscal 2001 increased 1.5%, or $1.1 million, from the comparable period in fiscal 2000. Total revenues for the first six months of fiscal 2001 increased $8.6 million, or 6.1%, over the first six months of fiscal 2000. The three-month increase is the result of a $2.2 million, or 19.1%, increase in services revenue offset by a $1.3 million, or 2.9%, decrease in software license fees revenue. The six-month increase is the result of a $5.9 million, or 7.2%, increase in software license fees revenue and a $3.3 million, or 12.1%, increase in services revenue, offset by a $0.5 million, or 1.5%, decrease in maintenance fee revenue. During the first quarter of fiscal 2000, the Company's large bank and merchant customers and potential new customers, in effect, locked down their systems in preparation for the Year 2000. This Year 2000 lock-down had a negative impact on the Company's Consumer e-Payments software license fees and services revenues due to the less than expected demand by customers and potential new customers to upgrade and enhance their current systems. In addition, since the Year 2000 cutover, the Company has found its customers increasingly scrutinizing their information technology purchases, which has led to further delays in software and services purchases. The Company believes overall demand for its products and services is increasing at a gradual pace. However, the Company believes that customer demand for its products and services will be slow to return to growth levels experienced prior to fiscal 2000. The increase in ILF and PUF revenue for the second quarter and the first six months of fiscal 2001 is a result of an increased demand for the Company's Consumer e-Payments products, offset by a decrease in demand for the Company's Electronic Business Infrastructure ICE product and a decrease in revenue associated with a significant Corporate Banking e-Payment customer project. In addition, the Company changed its sales compensation plans in fiscal 2001 for its Consumer e-Payments sales force to emphasize PUF contracts for both customer renewals and new customers rather than emphasizing ILF/MLF contracts. This change resulted in an increase in PUF revenue and a decrease in MLF revenue for the second quarter and the first six months of fiscal 2001. Maintenance fee revenues decreased in the first quarter of fiscal 2001 due to a decrease in customer demand for the Company's enhanced maintenance support. During the second quarter of fiscal 2001, demand for the Company's enhanced maintenance support returned to normal levels. The growth in services revenue is the result of increased demand for technical and project management services, which is primarily the result of an increased installed base of the Company's Consumer e-Payments products. Expenses. Total operating expenses for the second quarter of fiscal 2001 increased $4.2 million, or 5.8%, over the comparable period of fiscal 2000. Total operating expenses for the first six months of fiscal 2001 increased $12.3 million, or 8.6%, over the first six months of fiscal 2000. Amortization of goodwill and purchased intangibles has increased between fiscal years related to the acquisitions of WorkPoint Systems, Inc. in April 2000, Hospital Health Plan Corporation in May 2000 and MessagingDirect Ltd. in January 2001. Other changes in operating expense line items are discussed below. Cost of software license fees for the second quarter of fiscal 2001 was comparable to the second quarter of fiscal 2000. For the six months ended March 31, 2001, cost of software license fees increased $0.9 million over the comparable period of fiscal 2000. This increase was due primarily to an increase in royalties owed to the owners of third-party products. Cost of maintenance and services for the second quarter of fiscal 2001 increased $0.7 million, or 4.3%, over the comparable period in fiscal 2000. For the six months ended March 31, 2001, cost of maintenance and services increased $2.7 million, or 7.8%, over the comparable period of fiscal 2000. These increases were the result of personnel-related expenses supporting maintenance fees and services revenues, which increased $2.7 million, or 4.5%, for the first six months of fiscal 2001 over the comparable period of fiscal 2000. Research and development ("R&D") costs for the second quarter of fiscal 2001 increased $0.8 million, or 7.6%, over the comparable period in fiscal 2000. For the six months ended March 31, 2000, R&D costs increased $2.4 million, or 12.8%, over the comparable period of fiscal 2000. R&D consists primarily of compensation and related costs for R&D employees and contractors. R&D costs as a percentage of total revenues for the three and six months ended March 31, 2001 were 14.0% and 13.8%, respectively, as compared to 13.2% and 12.9%, respectively, for comparable periods of fiscal 2000. The Company capitalizes costs related to certain internally-developed software when the resulting products reach technological feasibility. Software development costs capitalized in the first six months of fiscal 2001 and 2000 totaled approximately $2.6 million and $4.1 million, respectively. Selling and marketing costs for the second quarter of fiscal 2001 was comparable to the second quarter of fiscal 2000. For the six months ended March 31, 2001, selling and marketing costs increased $2.2 million, or 6.1%, over the comparable period of fiscal 2000. The increase for the first six months of fiscal 2001 is due to an increase in sales personnel and marketing activities in each of the four business units. General and administrative costs for the second quarter of fiscal 2001 increased $0.9 million, or 5.9%, over the comparable period in fiscal 2000. For the six months ended March 31, 2001, general and administrative costs increased $2.4 million, or 8.0%, over the comparable period of fiscal 2000. The increase is attributable to an increase in bad debts expense and occupancy costs, offset by a decrease in personnel-related expenses. The decrease in personnel-related expenses is due to the consolidation of the Company's Consumer Banking, Electronic Commerce and Internet Banking operating units into the Consumer e-Payments business unit during the fourth quarter of fiscal 2000. During the quarter ending June 30, 2001, the Company will incur approximately $2.8 million as severance benefits to certain former executive officers in connection with their resignations. Other Income and Expenses. The increase in interest expense in fiscal 2001 is due to an increase in borrowings on the Company's line-of-credit facilities. Other expenses resulted primarily from foreign currency translation losses recognized by the Company. The Company continually evaluates the carrying value of its investment holdings and long-lived assets for evidence of impairment. During the first quarter of fiscal 2001, after considering current market conditions for technology companies and specific information regarding those companies in which the Company has an ownership interest, the Company determined that the declines in market value for certain of its investment holdings were "other than temporary" and a charge to earnings of $12.4 million for the declines in market value was required. The Company also expensed costs associated with the withdrawn IPO of Insession Technologies, Inc. totaling $1.9 million in the first quarter of fiscal 2001. These charges are reflected as non-recurring items under other expenses. Income Taxes. The effective tax rate for the first six months of fiscal 2001 was approximately 10% as compared to 41% for all of fiscal 2000. The effective tax rate for the first six months of fiscal 2001 was less than that of the comparable period for fiscal 2000 primarily due to non-deductible amortization expense associated with acquisitions accounted for as purchases and non-recognition of tax benefits for operating losses in certain foreign locations. As of March 31, 2001, the Company has deferred tax assets of $31.5 million and deferred tax liabilities of $2.6 million. Each quarter, the Company evaluates its historical operating results as well as its projections for the future to determine the realizability of the deferred tax assets. This analysis indicated that $19.9 million of the net deferred tax assets were more likely than not to be realized. Accordingly, the Company has a valuation allowance of $9.0 million as of March 31, 2001. The Company intends to analyze the realizability of the net deferred tax assets at each future reporting period. Such analysis may indicate that the realization of various deferred tax benefits is more likely than not and, therefore, the valuation reserve may be adjusted accordingly. Liquidity and Capital Resources As of March 31, 2001, the Company's principal sources of liquidity consisted of $20.7 million in cash and cash equivalents, and available bank lines of credit totaling approximately $29.2 million, with outstanding borrowings of approximately $21.2 million. The bank lines are subject to maintenance of certain covenants. The Company's net cash flows used in operating activities for the first six months of fiscal 2001 amounted to $1.0 million as compared to $6.4 million used during the first six months of fiscal 2000. The growth of the Company's billed and accrued receivables during the first six months of fiscal 2001 and 2000 are the primary reasons for the negative operating cash flows in the first six months of fiscal 2001 and 2000. A contributor to the Company's cash management program is the factoring of accrued receivables, whereby an interest in Company receivables is transferred on a non-recourse basis to third-party financial institutions in exchange for cash. During the first six months of fiscal 2001 and 2000, the Company generated operating cash flows from the factoring of accrued receivables of $8.5 million and $11.1 million, respectively. The Company has approximately $15 million of accrued receivables that may be sold in the future to third-party financial institutions under this program. The Company is actively pursuing the sale of a portion of these receivables as a means to generate cash, but there can be no assurance that the Company will be successful in its efforts to sell any of these receivables. The Company's net cash flows used in investing activities totaled $6.0 million and $13.2 million in the first six months of fiscal 2001 and 2000, respectively. The decrease in cash used in investing activities was due to a decrease in acquisition-related expenditures, and decreased purchases of software, property and equipment, offset by an additional advance during the first quarter of fiscal 2001 in the amount of $1.0 million to the Company's CEO as part of his employment and incentive compensation package. The acquisition of business amount in fiscal 2000 consists of the final payment of $3.1 million related to the acquisition of Insession Inc. The Company's net cash flows provided by financing activities was $4.7 million in the first six months of fiscal 2001 as compared to net cash flows used in financing activities of $10.7 million in the first six months of fiscal 2000. During the first six months of 2001, the Company had net borrowings on its bank line-of-credit facilities of $3.3 million. During the first six months of fiscal 2000, pursuant to a stock repurchase program approved by the Company's Board of Directors, the Company acquired 500,300 shares at an average cost of $26.67 per share, totaling approximately $13.3 million. The Company used cash flow from operations to fund the common stock repurchases. The Company is considering various alternatives for the Corporate Banking e-Payments and Health Payments Systems business units, including possible sales, spin-offs, strategic alliances, partnerships, third-party investors and initial public offerings. The Company recently discontinued pursuing strategic alternatives for the Electronic Business Infrastructure business unit since the value of the products and services it offers exceeds current technology company market valuations. The Company believes that its existing sources of liquidity, including cash provided by operating activities (which improved sequentially in the second quarter of fiscal 2001 over the first quarter of fiscal 2001 as a result of cost containment initiatives that have been implemented, accounts receivable improvements and an emphasis on PUF contracts) along with cash generated from its factoring program and borrowings available under its line-of-credit facilities, will satisfy the Company's projected working capital and other cash requirements for the foreseeable future. Any cash received upon successful divestiture of either of the business units described above would reduce the Company's reliance on borrowings under its line-of-credit facilities. In December 2000, the Company entered into an amendment to its primary line-of-credit facility increasing the aggregate commitment from $25.0 million to $30.0 million. The increased commitment expired on March 31, 2001. Consequently, as of March 31, 2001, the commitment under its primary line-of-credit facility returned to $25.0 million. In May 2001, the Company and its U.S. bank agreed to amend the Company's primary line-of-credit facility reducing the line-of-credit facility from $25.0 million to $15.0 million and extending the facility's maturity date from May 31, 2001 to June 30, 2001. The Company is currently negotiating with several financial institutions for a replacement line-of-credit. Although no assurances can be given, the Company believes a replacement line-of-credit of approximately $25.0 million will be in place prior to June 30, 2001. Forward-Looking Statements The statements in this report regarding projected results are preliminary and "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. In addition, this report contains other forward-looking statements including statements regarding the Company's or third parties' expectations, predictions, views, opportunities, plans, strategies, beliefs and statements of similar effect. The forward-looking statements in this report are subject to a variety of risks and uncertainties. Actual results could differ materially. Factors that could cause actual results to differ include but are not limited to the following: o The corporate divestiture strategy is subject to numerous factors, including market conditions and perception, demand for the other businesses by potential investors or potential acquirers, personnel, tax, business, general economic conditions, viability of businesses as stand-alone operations, and other factors that could affect the Company's decisions and ability to separate businesses, to divest, raise capital, or implement other alternatives for such businesses, and to implement other aspects of the Company's corporate strategy. There can be no assurance that the Company will implement any aspect of the corporate strategy or that if implemented the strategy will be successful. o The Year 2000 lock-down has interrupted the Company's normal sales cycle and therefore is likely to have a negative impact on the Company's revenues and net income for the remainder of fiscal 2001 and beyond. The Company also believes customer demand for system upgrades and enhancements will be slow to return to normal growth levels, as many of the Company's customers upgraded and enhanced their systems prior to the Year 2000. There can be no assurance that the Company's growth rates will return to historical levels. o The acquisition of MessagingDirect is subject to numerous risks, including the following: (i) MessagingDirect is in a highly competitive industry, (ii) MessagingDirect does not have a significant market presence, significant revenues, or widespread acceptance or prolonged use of its products, (iii) MessagingDirect has not been profitable, (iv) the electronic statement presentation and electronic bill presentment and payment markets may not achieve the predicted growth rates, (v) MessagingDirect's products, personnel, and operations may be difficult to combine with those of the Company, the products may not be accepted by the Company's customer base, and there will be significant integration costs of combining the businesses, and (vi) the acquisition will have a dilutive impact on earnings per share and amortization of intangible assets will have an adverse effect on earnings. o The Company is subject to risks of conducting international operations including difficulties in staffing and management, reliance on independent distributors, fluctuations in foreign currency exchange rates, compliance with foreign regulatory requirements, variability of foreign economic conditions, and changing restrictions imposed by U.S. export laws. o The Company will continue to derive a majority of its total revenues from licensing its BASE24 family of software products and providing services and maintenance related to those products. Any reduction in demand for, or increase in competition with respect to, BASE24 products would have a material adverse effect on the Company's financial condition and results of operations. o The Company's business is concentrated in the banking industry, making it susceptible to a downturn in that industry. o Fluctuations in quarterly operating results may result in volatility in the Company's stock price. No assurance can be given that operating results will not vary. The Company's stock price may also be volatile, in part, due to external factors such as announcements by third parties or competitors, inherent volatility in the high-technology sector and changing market conditions in the industry. o The diversion of management's time and attention to the search for a new permanent CEO, and related transition issues, may temporarily dilute management's focus on the Company's day-to-day operations. For a detailed discussion of these and other risk factors, interested parties should review the Company's filings with the Securities and Exchange Commission, including Exhibit 99.01 to the Company's Annual Report on Form 10-K for the fiscal year ended September 30, 2000. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK There have been no material changes to the Company's market risk for the six months ended March 31, 2001. See the Company's Annual Report on Form 10-K for the fiscal year ended September 30, 2000 for additional discussions regarding quantitative and qualitative disclosures about market risk.

(c) On January 11, 2001, TSA or its subsidiaries issued the securities listed below in exchange for all of the outstanding securities of MessagingDirect Ltd. ("MDL"), an Alberta, Canada company. The issuances were exempt from registration pursuant to Section 3(a)(10) of the Securities Act of 1933, as amended. The securities were issued pursuant to a plan of arrangement which was approved by the Court of Queen's Bench (Alberta), Canada after holding a hearing. The securities were issued pursuant to the plan of arrangement to the then securityholders of MDL (or with respect to the share of TSA Special Voting preferred stock discussed below, to a trustee for the benefit of certain of such securityholders). The court's order approving the plan of arrangement stated that the court was satisfied that the terms and conditions of the plan of arrangement were fair and reasonable to the MDL securityholders, both procedurally and substantively. The court was advised before the hearing that its approval would constitute the basis for a claim to the Section 3(a)(10) exemption. MDL securityholders were given notice of the hearing and the right to appear. o 1,778,429 shares of TSA Class A Common Stock. o 1,410,942 shares of Exchangeable Shares of TSA Exchangeco Limited, a Nova Scotia subsidiary of TSA. The Exchangeable Shares can be exchanged on a one-for-one basis into shares of TSA's Class A Common Stock. The holders of Exchangeable Shares have rights to direct the voting of the share of TSA Special Preferred Stock described below. o One share of TSA Special Preferred Voting Stock. This share was issued to Wells Fargo Bank Minnesota, National Association, as Trustee of the trust created for the benefit of holders of the Exchangeable Shares, to be held of record by the Trustee for and on behalf of, and for the use and benefit of, the holders of the Exchangeable Shares. The Special Preferred Voting Stock entitles the Trustee to cast the number of votes equal to the number of Exchangeable Shares outstanding, voting as a single class with the Class A Common Stock. Each holder of Exchangeable Shares is entitled to instruct the Trustee on how to vote with respect to such holder's Exchangeable Shares. o Options to purchase 167,980 shares of TSA Class A Common Stock. These options were issued to holders of MessagingDirect Ltd. employee stock options to replace those options. The replacement options have an exercise price of one cent per share of TSA Class A Common Stock because, pursuant to the terms of the acquisition, the number of shares covered by the options was reduced by a formula intended to replicate a cashless exercise. On January 11, 2001, TSA Exchangeco Limited issued 600,000 shares of nonvoting, Canadian dollar denominated preferred stock with a 7% per annum dividend rate, to another TSA subsidiary which in turn sold them to ten TSA management level employees who are not executive officers and who each purchased 60,000 of the shares. The sale was exempt from registration pursuant to Section 4(2) of the Securities Act. The securities were offered only to these ten employees, the employees agreed to resale restrictions, and the certificates representing the securities were legended. The purchase price for the preferred shares was $1,490,000 Canadian dollars, which equated to one million U.S. dollars on the date of issuance. The preferred shares are exchangeable by the holders for TSA Class A Common Shares after two years from the date of issuance of the preferred shares or earlier upon a change of control of TSA. Subject to adjustments, the number of TSA Class A Common Stock shares issuable upon exchange of a preferred share (the "Ratio") is equal to the quotient of the purchase price of the preferred stock (plus any accrued and unpaid dividends) and 115% of the Canadian dollar equivalent of the average market price for TSA Class A Common Stock for the 20-day trading period ended prior to the date of issuance of the preferred shares as determined in the manner set out in the preferred share provisions. As of the date of issuance of the preferred shares and subject to adjustments, the total number of TSA Class A Common Stock shares that would be issuable upon exchange of all of the preferred shares was 67,679. TSA Exchangeco Limited or other TSA subsidiaries may elect to redeem the preferred shares after two years from the date of their issuance, or earlier upon a change of control of TSA or termination of employment of the holder, for TSA Class A Common Stock with a market value (as determined based on an average market price) at the time of redemption equal to the greater of (i) the purchase price (plus any accrued and unpaid dividends) or (ii) the fair market value of the preferred shares. If there is no agreement on the fair market value, then it will be determined pursuant to the preferred share provisions which provide, in general, that it will equal the number of TSA shares determined pursuant to the Ratio plus the then present value of any unpaid dividends payable with respect to periods after the early redemption through the mandatory redemption date. If the preferred shares have not been earlier exchanged or redeemed, then they are to be mandatorily redeemed for cash equal to the purchase price plus any accrued but unpaid dividends on the fifth anniversary date of their issuance.

If the MDL Securityholders approve the Arrangement, MDL will take the necessary steps to submit the Arrangement to the Court and apply for a final order of the Court approving the Arrangement in such fashion as the Court may direct. Upon receipt of the final order and satisfaction of all conditions set forth in Articles VIII and IX or waiver of such conditions, the Articles of Arrangement shall be filed with the Registrar under the ABCA giving effect to the Arrangement and the transactions specified in Section 2.2 of the Plan of Arrangement shall occur and shall be deemed to occur in the order specified without any further act or formality. 2.2 Arrangement Subject to the provisions of Sections 2.3 (Dissenting Shares) and 2.4 (Escrow of Shares) hereof and all as subject to the Plan of Arrangement, at the Effective Time, without any action on the part of the holders thereof, and in the following sequence: (a) The MDL Stock Option Plan will be amended to permit acceleration of vesting of the MDL Options and adoption of the MDL Stock Option Plan by TSA. (b) Each Stonebridge Option and Compensation Warrant will be converted into and exchanged for the number of fully-paid and non-assessable MDL Class A Shares equal to (i) the number of MDL Class A Shares purchasable on the Effective Date pursuant to such Stonebridge Option or Compensation Warrant, as applicable, less (ii) the quotient derived by dividing (A) the aggregate exercise price for the MDL Class A Shares purchasable under such Stonebridge Option or Compensation Warrant, by (B) the product derived by multiplying (I) the Exchange Ratio by (II) the Average Trading Price. For purposes of this calculation, all dollar amounts will be calculated using Canadian dollars or the Canadian Dollar Equivalent. (c) Prior to the Effective Date and in accordance with the Plan of Arrangement, each holder of a MDL Class A Share will have completed an election form to elect to receive Exchangeable Shares or TSA Class A Common Shares from TSA Exchangeco in exchange for their MDL Class A Shares or will be deemed to have elected to receive TSA Class A Common Shares. (d) Each TSA Elected Share (as such term is defined in the Plan of Arrangement) will, pursuant to the terms hereof, be transferred to TSA Exchangeco in exchange for a number of fully paid and non-assessable TSA Class A Common Shares based on the Exchange Ratio. The name of each such holder will be removed from the register of MDL Class A Shares and added to the register of TSA Class A Common Shares. TSA Exchangeco will be recorded as the registered holder of such MDL Class A Shares so exchanged and will be deemed to be the legal and beneficial owner thereof. In lieu of fractional TSA Class A Common Shares, each holder of a MDL Class A Share who otherwise would be entitled to receive a fraction of a TSA Class A Common Share on the exchange of all such holder's MDL Class A Shares will be paid by TSA Exchangeco an amount determined as set forth in the Plan of Arrangement. (e) Each Exchangeable Elected Share (as such term is defined in the Plan of Arrangement) will, pursuant to the terms hereof, be transferred to TSA Exchangeco in exchange for a number of fully paid and non-assessable Exchangeable Shares based on the Exchange Ratio. The name of each such holder will be removed from the register of MDL Class A Shares and added to the register of Exchangeable Shares. TSA Exchangeco will be recorded as the registered holder of such MDL Class A Shares so exchanged and will be deemed to be the legal and beneficial owner thereof. In lieu of fractional Exchangeable Shares, each holder of a Class A Share who otherwise would be entitled to receive a fraction of an Exchangeable Share on the exchange of all such holder's MDL Class A Shares will be paid by TSA Exchangeco an amount determined as set forth in the Plan of Arrangement. (f) Each holder of a TSA Elected Share shall receive additional TSA Class A Common Shares from TSA Exchangeco ("Additional Consideration"). The amount of the Additional Consideration payable to each holder of a TSA Elected Share will equal the product derived by multiplying (i) 200,000, by (ii) the quotient derived by dividing the number of TSA Elected Shares held by such holder by the aggregate number of TSA Elected Shares. In lieu of fractional TSA Class A Common Shares, each holder of a TSA Elected Share who otherwise would be entitled to receive a fraction of a TSA Class A Common Share will be paid by TSA Exchangeco an amount determined in accordance with the Plan of Arrangement. (g) Each of the MDL Options will be converted into an option to purchase ("Replacement TSA Option") that number of TSA Class A Common Shares equal to (i) the product of the number of MDL Class A Shares subject to such MDL Option at the Effective Time multiplied by the Exchange Ratio, less (ii) the quotient derived by dividing (A) the aggregate exercise price for the MDL Class A Shares subject to such MDL Option by (B) the Average Trading Price. The exercise price of each TSA Class A Common Share subject to such Replacement TSA Option will equal $0.01 per share. If the foregoing calculation results in an exchanged MDL Option being exercisable for a fraction of a TSA Class A Common Share, then the number of TSA Class A Common Shares subject to such option will be rounded down to the nearest whole number of shares. The obligations of MDL under the MDL Options as so converted shall be assumed by TSA. For purposes of this calculation, all dollar amounts will be calculated using Canadian dollars or the Canadian Dollar Equivalent. (h) In consideration of the grant of the Liquidation Call Right, Redemption Call Right and Retraction Call Right (as such terms are defined in the Plan of Arrangement), TSA will issue to and deposit with the Trustee the Special Voting Share to be thereafter held of record by the Trustee as trustee for and on behalf of, and for the use and benefit of, the holders of the Exchangeable Shares in accordance with the Voting and Exchange Trust Agreement. (i) All of the Escrowed Shares will be deposited with the Escrow Agent under the Escrow Agreement. 2.3 Dissenting Shares Holders of MDL Class A Shares may exercise rights of dissent with respect to such shares in connection with the Arrangement pursuant to and in the manner set forth in the Plan of Arrangement as may be modified by the Interim Order or the Final Order. MDL shall give TSA (i) prompt notice of any written demands of a right of dissent, withdrawals of such demands, and any other instruments served pursuant to the ABCA and received by MDL, and (ii) the opportunity to participate in all negotiations and proceedings (to the extent permitted by any judicial authority having jurisdiction) with respect to such rights. MDL shall not, except with the prior written consent of TSA, voluntarily make any payment with respect to any such rights or offer to settle or settle any such rights. All payments to such dissenting shareholders shall be the sole responsibility of MDL. 2.4 Escrow of Shares At the Effective Time, MDL shall deliver to the Escrow Agent, a certificate or certificates representing the Escrowed Shares for the purposes of securing any indemnity obligations of the Indemnifying Shareholders, all as more particularly described in the Escrow Agreement. 2.5 Other Effects of the Arrangement At the Effective Time: (a) the persons recommended by TSA will be elected as directors of MDL; (b) the persons designated by TSA will be elected as officers of MDL; and (c) the Arrangement will, from and after the Effective Time, have all of the effects provided by applicable Law, including the ABCA. 2.6 Exchange of Call Rights for Put Rights The Liquidation Call Right, Redemption Call Right and Retraction Call Right (as such terms are defined in the Plan of Arrangement) to be granted to TSA (which, subject to the terms of the Plan of Arrangement, may be assigned or delegated by TSA to TSA Holdco) pursuant to the terms of the Plan of Arrangement will be granted by the holders of Exchangeable Shares (other than TSA and its Affiliates) to TSA as consideration for the Voting Rights, Exchange Rights and Automatic Exchange Rights (as such terms are defined in the Voting and Exchange Trust Agreement) to be granted by TSA to the Trustee for the benefit of the MDL Securityholders in the Voting and Exchange Trust Agreement.

2.7 Adjustments to Exchange Ratio Prior to Effective Date If, after the Exchange Ratio has been set but prior to the Effective Time, TSA recapitalizes its outstanding capital stock through a subdivision of its outstanding shares into a greater number of shares, or a combination of its outstanding shares into a lesser number of shares, or reorganizes, reclassifies or otherwise changes its outstanding shares into the same or a different number of shares of other classes, or declares a dividend on its outstanding shares payable in shares of its capital stock or securities convertible into shares of its capital stock, or completes a rights offering for TSA Class A Common Shares solely to its existing shareholders at a price less than market price, or grants a material option solely to existing shareholders to acquire TSA Class A Common Shares at a price less than market price and the record date for any such action is prior to the Effective Time, then the Exchange Ratio will be adjusted proportionately. 2.8 Total Number of Shares For the avoidance of doubt, subject to Section 2.7, the total of (i) the TSA Class A Common Shares (including the TSA Class A Common Shares underlying the Replacement TSA Options) and (ii) the Exchangeable Shares to be issued or transferred by the TSA Companies hereunder shall equal 3,357,500, less the number of such shares to which MDL Securityholders exercising rights of dissent would otherwise be entitled.

ARTICLE X TERMINATION OF AGREEMENT 10.1 Termination This Agreement may be terminated at any time prior to the Effective Time, whether before or after approval of the Plan of Arrangement by the MDL Securityholders and by the Court: (a) by mutual agreement of MDL and TSA; (b) by MDL, if there has been a breach by TSA of any representation, warranty, covenant or agreement set forth in this Agreement on the part of TSA, or if any representation of TSA shall have become untrue, in either case which has or can reasonably be expected to have a Material Adverse Effect on TSA and its Affiliates and which TSA fails to cure within fifteen (15) Business Days after written notice thereof from MDL (except that no cure period shall be provided for a breach by TSA which by its nature cannot be cured); (c) by MDL, if the conditions set forth in Subsections 5.9(b) and 5.9(c) have been satisfied and (i) the board of directors of MDL fails to recommend or withdraws its recommendation of this Agreement or the Plan of Arrangement or shall have resolved to do so pursuant to Section 5.9 (No Other Negotiations); or (ii) if the board of directors of MDL shall have recommended to the MDL Securityholders a Superior Proposal or resolved to do so. Notwithstanding the opening language of this Section 10.1, MDL's right to terminate in this Subsection only arises after the MDL Securityholders fail to approve the Plan of Arrangement at the MDL Securityholders Meeting or any adjournment thereof and MDL has paid up to $1,000,000.00 of the TSA Expenses as required by Section 11.3 (Termination Fees and Expenses). (d) by TSA, if there has been a breach by MDL of any representation, warranty, covenant or agreement set forth in this Agreement on the part of MDL, or if any representation of MDL shall have become untrue, in either case which has or can reasonably be expected to have a Material Adverse Effect on the MDL Companies or TSA, and which MDL fails to cure within fifteen (15) Business Days after written notice thereof from TSA (except that no cure period shall be provided for a breach by MDL which by its nature cannot be cured); (e) by TSA, (i) if the board of directors of MDL fails to recommend or withdraws its recommendation of this Agreement or the Plan of Arrangement or shall have resolved to do so; or (ii) if the board of directors of MDL shall have recommended to the MDL Securityholders any Business Combination Transaction or resolved to do so; or (iii) if an offer to acquire 50% of more of the outstanding MDL Class A Shares is commenced, and the board of directors of MDL fails to recommend against the MDL Securityholders tendering their MDL Class A Shares into such offer; (f) by TSA, if the MDL Securityholders fail to approve the Plan of Arrangement at the MDL Securityholders Meeting; (g) by TSA or MDL, if the Court fails to issue an interim or final order approving the Plan of Arrangement; (h) by MDL or TSA, if all the conditions for Closing the Arrangement shall not have been satisfied or waived on or before 5:00 p.m., Toronto time on the date which is one hundred and twenty (120) days following execution of this Agreement or such later date as may be agreed upon in writing by MDL and TSA, other than as a result of a breach of this Agreement by the terminating party; or (i) by MDL or TSA, if a permanent injunction or other order by any Governmental Entity shall have been issued and shall have become final and non-appealable that would (i) make illegal or otherwise restrain or prohibit the consummation of the Arrangement or any other transaction contemplated hereby, (ii) prohibit TSA's ownership or operation of all or any portion of the business or assets of the MDL Companies or (iii) compel TSA to dispose of or hold separate all or any portion of the business or assets of the MDL Companies. 10.2 Notice of Termination Any termination of this Agreement under Section 10.1 above will be effective by the delivery of written notice by the terminating party to the other party hereto. 10.3 Effect of Termination In the case of any termination of this Agreement as provided in this Article X, this Agreement shall be of no further force and effect (except as provided in Article XI). Termination or expiration of this Agreement and the Ancillary Agreements through any means and for any reason shall not relieve the parties of any obligation occurring prior thereto and shall be without prejudice to the rights and remedies of either party with respect to any prior breach of any provision of this Agreement. No termination of this Agreement shall affect the obligations of the parties contained in the Mutual Non-Disclosure Agreement entered into between TSA and MDL on May 10, 2000. 10.4 Effect of Termination on Distribution Agreement In the case of any termination of this Agreement as provided in this Article X, the Distribution Agreement shall contemporaneously terminate only if this Agreement is terminated: (a) by MDL, pursuant to (i) Subsection 10.1(b); or (ii) Subsection 10.1(h) due to a breach by TSA of any representation, warranty, covenant or agreement set forth in this Agreement on the part of TSA which has, or can reasonably be expected to have, a Material Adverse Effect on TSA and its Affiliates; or (b) by TSA, pursuant to Subsection 10.1(h) due to a breach by MDL of any representation, warranty, covenant or agreement set forth in this Agreement on the part of MDL which has not, or cannot reasonably be expected to have, a Material Adverse Effect on the MDL Companies. For the sake of clarity, unless one of the foregoing conditions is satisfied, the Distribution Agreement shall be unaffected by termination of this Agreement.

ARTICLE XI SURVIVAL OF REPRESENTATIONS, WARRANTIES AND COVENANTS; INDEMNITY 11.1 Survival of Representations and Warranties All representations, warranties and covenants of MDL and each of the TSA Companies, respectively, contained in this Agreement will survive, regardless of any investigation made by, or on behalf of, the parties to this Agreement, until the first (1st) anniversary of the Effective Time or as noted below in Section 11.2. Notwithstanding anything in this Agreement, the aggregate liability of the TSA Companies whether to MDL or to the MDL Securityholders shall in no event exceed the aggregate value of 20% of the TSA Class A Common Shares delivered at Closing and TSA Class A Common Shares underlying the Exchangeable Shares based on the Average Trading Price. 11.2 Survival of Certain Covenants Certain covenants of the parties contained herein shall not be extinguished by the Closing or the termination of this Agreement in accordance with the terms of Article X hereof in the following manner: (a) The covenants of the parties contained in Sections 12.7 (Expenses), 12.8 (Legal Fees), 12.10 (No Personal Liability) and 12.12 (Further Assurances) shall survive both the Closing and the termination of this Agreement in accordance with the terms of Article X hereof; (b) The covenants of TSA and its Affiliates, contained in Section 6.8 (Non-Solicitation) and the covenants of the parties contained in Section 12.13 (Public Announcement) of this Agreement shall survive the termination of this Agreement in accordance with the terms of Article X hereof and remain operative and in full force and effect for the periods stated therein; (c) The covenants of MDL and TSA contained in, respectively, Section 5.13 and 6.5 (Employee Inventive Arrangements) of this Agreement shall survive the Closing and shall remain operative and in full force and effect; and (d) The covenant of TSA contained in Section 6.7 (Registration Statement) shall survive the Closing and remain in full force and effect until there are no Exchangeable Shares held by holders other than TSA and its Affiliates. 11.3 Termination Fees and Expenses (a) MDL shall pay TSA the Alternative Proposal Fee and the TSA Expenses if: (i) this Agreement is terminated pursuant to Subsections 10.1(c) or 10.1(e) and any Business Combination Transaction is thereafter consummated within nine (9) months of such termination; (ii) this Agreement is terminated pursuant to Subsection 10.1(f) as a result of the failure of the MDL Securityholders to approve the Arrangement and a Business Combination Transaction proposal shall have been made prior to such vote, and any Business Combination Transaction is thereafter consummated within nine (9) months of such termination; or (iii)this Agreement is terminated pursuant to Subsection 10.1(g) as a result of the failure of the Court to issue an interim or final order approving this Agreement and the Arrangement and a Business Combination Transaction proposal shall have been made prior to such termination and any Business Combination Transaction is thereafter consummated within nine (9) months of such termination. (b) MDL shall not be required to pay TSA Expenses in excess of one million dollars ($1,000,000.00) pursuant to this Section 11.3. (c) Payment of the TSA Expenses by MDL to TSA arising pursuant to the terms of Subsection 11.3(a)(i) shall be made prior to termination of this Agreement. Payment of the Alternative Proposal Fee by MDL to TSA arising pursuant to the terms of Subsection 11.3(a)(i) shall be made contemporaneously with the consummation of such Business Combination Transaction. For the sake of clarity, even if a Business Combination Transaction is not consummated within nine (9) months of a termination pursuant to Subsections 10.1(c) or 10.1(e), MDL shall be required to pay the TSA Expenses prior to such termination but shall not be required to pay the Alternative Proposal Fee. (d) Payment of the Alternative Proposal Fee and the TSA Expenses by MDL to TSA arising pursuant to the terms of Subsection 11.3(a)(ii) or (iii) shall be made contemporaneously with the consummation of such Business Combination Transaction. 11.4 Indemnification of the Indemnitees Without limiting any other rights the Indemnitees (as such term is defined in the Plan of Arrangement) may have as against Persons other than the Indemnifying Shareholders in respect of Losses suffered by TSA and its Affiliates in connection with this Agreement, at the Effective Time, the Indemnitees shall be entitled to exercise the rights set forth in Section 7.1 of the Plan of Arrangement and in the Escrow Agreement against the Indemnifying Shareholders in the event of any Losses suffered or incurred by an Indemnitee resulting from the inaccuracy or breach of any representation or warranty of MDL, any breach of or failure to perform any covenant or agreement of MDL in the Combination Agreement or in any certificate furnished by MDL pursuant to the Combination Agreement at Closing or any of the Indemnifying Shareholders or any other matter set forth herein to the extent and on the terms set forth in the Escrow Agreement. The Indemnitees' sole remedy for such indemnification from the Indemnifying Shareholders is as set out in Section 7.1 of the Plan of Arrangement and the Escrow Agreement. ARTICLE XII MISCELLANEOUS 12.1 Governing Law The laws of the Province of Alberta, Canada (irrespective of its choice of law principles) will govern the validity of this Agreement, the construction of its terms and the interpretation and enforcement of the rights and duties of the parties hereto. 12.2 Assignment Binding Upon Successors and Assigns None of the parties hereto may assign any of its rights or obligations hereunder or under the Ancillary Agreements without the prior written consent of the other parties hereto or thereto. This Agreement will be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns. The TSA Companies expressly agree and acknowledge that the representations, warranties and covenants of the TSA Companies herein are for the benefit of and shall inure to the benefit of the MDL Securityholders in addition to MDL. 12.3 Severability If any provision of this Agreement, or the application thereof, will for any reason and to any extent be invalid or unenforceable, the remainder of this Agreement and application of such provision to other persons or circumstances will be interpreted so as reasonably to effect the intent of the parties hereto. The parties further agree to replace such void or unenforceable provision of this Agreement with a valid and enforceable provision that will achieve, to the greatest extent possible, the economic, business, legal and other purposes of the void or unenforceable provision. 12.4 Facsimile and Counterparts This Agreement may be executed by facsimile and in any number of counterparts, each of which will be deemed to be an original as regards any party whose signature appears thereon and all of which together will constitute one and the same instrument. This Agreement will become binding when one or more counterparts hereof, individually or taken together, will bear the signatures of all the parties reflected hereon as signatories. 12.5 Other Remedies Except as otherwise provided herein, any and all remedies herein expressly conferred upon a party will be deemed cumulative with, and not exclusive of, any other remedy conferred hereby or by Law on such party, and the exercise of any one remedy will not preclude the exercise of any other.

12.6 Amendment and Waivers Any term or provision of this Agreement may be amended, and the observance of any term of this Agreement may be waived (either generally or in a particular instance and either retroactively or prospectively) only by a writing signed by the party to be bound thereby. The waiver by a party of any breach hereof or default in the performance hereof will not be deemed to constitute a waiver of any other default or any succeeding breach or default. The Agreement may be amended by the parties hereto at any time before or after approval of the MDL Securityholders, but, after such approval, no amendment will be made which by applicable Law requires the further approval of the MDL Securityholders without obtaining such further approval. 12.7 Expenses Each party will bear its respective fees and expenses (including the fees and expenses of legal counsel, accountants and investment bankers) incurred with respect to this Agreement, and the transactions contemplated hereby; provided, that, in the event that this transaction is consummated, the total of all such fees and expenses incurred by MDL and for which it shall be responsible (including the fees and expenses described in Section 3.16 hereof) shall not exceed CDN$1,800,000.00. MDL has provided TSA with a budget of all such fees and expenses required in connection with the completion of the transactions contemplated by this Agreement and shall use its commercially reasonable efforts to consummate such transactions without exceeding the budgeted amount and shall not enter into any agreement or take any action inconsistent with the foregoing. If MDL's aggregate fees and expenses exceed CDN$1,800,000.00, then such excess amount shall be paid by the Indemnifying Shareholders pursuant to Section 7.1 of the Plan of Arrangement and the terms of the Escrow Agreement. 12.8 Legal Fees Should suit be brought to enforce or interpret any part of this Agreement, the prevailing party will be entitled to recover, as an element of the costs of suit and not as damages, reasonable legal fees to be fixed by the court (including, without limitation, costs, expenses and fees on any appeal). The prevailing party will be entitled to recover its costs of suit, regardless of whether such suit proceeds to final judgment. 12.9 Notices All notices and other communications pursuant to this Agreement shall be in writing and deemed to be sufficient if contained in a written instrument and shall be deemed given if delivered personally, by facsimile, sent by nationally-recognized overnight courier or mailed by registered or certified mail (return receipt requested), postage prepaid, to the parties at the following address (or at such other address for a party as shall be specified by like notice):

                           ARTICLE 2     ARRANGEMENT

2.1      Binding Effect

This Plan of Arrangement will become effective at, and be binding at and after,
the Effective Time on:

(a)  MDL;
(b)  TSA;
(c)  TSA  Holdco;
(d)  TSA  Exchangeco;
(e)  All holders and beneficial  holders  of Class A Shares;
(f)  All holders of MDL  Options, Stonebridge Options and Compensation Warrants;
(g)  All  holders  and beneficial  holders  of  Exchangeable  Shares;  and
(h)  All  holders  and beneficial  holders  of TSA  Class A Common Shares issued
     at Closing in exchange for Class A Shares or issued in exchange for
     Exchangeable  Shares from time to time.

2.2      Arrangement

At the Effective Time, the following transactions will occur and will be deemed
to occur in the following order without any further act (including any action on
the part of the holders thereof) or formality:

(a)  The MDL Stock  Option  Plan will be  amended  as set out in  Appendix  A to
     permit  acceleration  of vesting of the MDL Options and adoption of the MDL
     Stock Option Plan by TSA;

(b)  Each Stonebridge Option and Compensation Warrant will be converted into and
     exchanged for the number of fully-paid  and  non-assessable  Class A Shares
     equal to (i) the number of Class A Shares purchasable on the Effective Date
     pursuant to such Stonebridge Option or Compensation Warrant, as applicable,
     less (ii) the quotient derived by dividing (A) the aggregate exercise price
     for the  Class A  Shares  purchasable  under  such  Stonebridge  Option  or
     Compensation  Warrant,  by (B) the product  derived by multiplying  (I) the
     Exchange  Ratio  by  (II)  the  Average  Trading  Price.   The  holders  of
     Stonebridge Options and Compensation  Warrants may deliver their notices of
     exercise in lieu of a  certificate  for Class A Shares for the  purposes of
     Sections 4.1 and 4.2. For purposes of this calculation,  all dollar amounts
     will  be  calculated   using  Canadian   dollars  or  the  Canadian  Dollar
     Equivalent;

(c)  Each  Class  A  Share  in  respect  of  which a duly  completed  Letter  of
     Transmittal and Election Form has not been deposited with the Depositary on
     or  prior to the  Election  Deadline  (other  than  Class A Shares  held by
     Dissenting  Shareholders  who are  ultimately  entitled to be paid the fair
     value  of the  Class A  Shares  held by them)  will be  deemed  to be a TSA
     Elected Share;

(d)  Each TSA Elected Share will,  pursuant to the terms hereof,  be transferred
     to TSA Exchangeco in exchange for a number of fully paid and non-assessable
     TSA Class A Common  Shares  based on the Exchange  Ratio.  The name of each
     such holder will be removed  from the  register of Class A Shares and added
     to the  register  of TSA  Class A Common  Shares.  TSA  Exchangeco  will be
     recorded as the  registered  holder of such Class A Shares so exchanged and
     will be  deemed  to be the  legal  and  beneficial  owner  thereof.  If the
     calculation  of the  number  of TSA  Class A  Common  Shares  based  on the
     Exchange Ratio results in an entitlement to a fractional  interest in a TSA
     Class A Common Share,  such entitlement shall be dealt with as set forth in
     Section 4.4 (No Fractional Shares) hereto;

(e)  Each  Exchangeable  Elected Share will,  pursuant to the terms  hereof,  be
     transferred  to TSA  Exchangeco  in exchange for a number of fully paid and
     non-assessable Exchangeable Shares based on the Exchange Ratio. The name of
     each such  holder will be removed  from the  register of Class A Shares and
     added to the  register  of  Exchangeable  Shares.  TSA  Exchangeco  will be
     recorded as the  registered  holder of such Class A Shares so exchanged and
     will be  deemed  to be the  legal  and  beneficial  owner  thereof.  If the
     calculation  of the number of  Exchangeable  Shares  based on the  Exchange
     Ratio results in an entitlement to a fractional interest in an Exchangeable
     Share, such entitlement shall be dealt with as set forth in Section 4.4 (No
     Fractional Shares) hereto;

(f)  Each  holder of a TSA Elected  Share will  receive  additional  TSA Class A
     Common Shares from TSA Exchangeco ("Additional Consideration").  The amount
     of the  Additional  Consideration  payable to each  holder of a TSA Elected
     Share will equal the product  derived by multiplying  (i) 200,000,  by (ii)
     the quotient  derived by dividing the number of TSA Elected  Shares held by
     such  holder by the  aggregate  number of TSA  Elected  Shares.  In lieu of
     fractional  TSA Class A Common  Shares,  each holder of a TSA Elected Share
     who  otherwise  would be  entitled  to receive a fraction  of a TSA Class A
     Common Share will be paid by TSA  Exchangeco  an amount  determined  as set
     forth in Section 4.4 (No Fractional Shares) hereto;

(g)  Each of the MDL  Options  will be  converted  into an  option  to  purchase
     ("Replacement  TSA Option")  that number of TSA Class A Common Shares equal
     to (i) the product of the number of MDL Class A Shares  subject to such MDL
     Option at the Effective Time  multiplied by the Exchange  Ratio,  less (ii)
     the quotient  derived by dividing (A) the aggregate  exercise price for the
     MDL Class A Shares  subject to such MDL Option by (B) the  Average  Trading
     Price. The exercise price per share of TSA Class A Common Shares subject to
     such  Replacement  TSA Option will equal $0.01 per share.  If the foregoing
     calculation  results in an  exchanged  MDL Option being  exercisable  for a
     fraction  of a TSA  Class A Common  Share,  then the  number of TSA Class A
     Common  Shares  subject to such option will be rounded  down to the nearest
     whole number of shares.  The obligations of MDL under the MDL Options as so
     converted  will be assumed by TSA.  For purposes of this  calculation,  all
     dollar amounts will be calculated  using  Canadian  dollars or the Canadian
     Dollar Equivalent;

(h)  In consideration  of the grant of the Liquidation  Call Rights,  Redemption
     Call Rights and Retraction Call Rights,  TSA will issue to and deposit with
     the Trustee the Special Voting Share to be thereafter held of record by the
     Trustee as trustee  for and on behalf of, and for the use and  benefit  of,
     the holders of the  Exchangeable  Shares in accordance  with the Voting and
     Exchange Trust Agreement; and

(i)  All of the Escrowed  Shares will be  deposited  with the Escrow Agent under
     the Escrow Agreement.


2.3      Elections

(a)  Each  Person  who,  at or prior to the  Election  Deadline,  is a holder of
     record  of Class A  Shares,  will be  entitled,  with  respect  to all or a
     portion of such  shares,  to make an election  at or prior to the  Election
     Deadline  to receive  Exchangeable  Shares or TSA Class A Common  Shares in
     exchange for such holder's Class A Shares on the basis set forth herein and
     in  the  Letter  of   Transmittal   and  Election   Form;   provided  that,
     notwithstanding anything to the contrary herein, a holder of Class A Shares
     who is not an  Eligible  Holder  will not be  entitled  to elect to receive
     Exchangeable Shares and any such election otherwise made by any such holder
     will be deemed to be an election to receive a TSA Class A Common Share.

(b)  Each  holder  of  Stonebridge  Options  or  Compensation  Warrants  will be
     entitled,  with  respect  to all or a part of such  Stonebridge  Options or
     Compensation  Warrants,  to make an  election  at or prior to the  Election
     Deadline  to receive  Exchangeable  Shares or TSA Class A Common  Shares in
     exchange of such holder's  Stonebridge Options or Compensation  Warrants on
     the basis set forth  herein and in the Letter of  Transmittal  and Election
     Form;  provided that,  notwithstanding  anything to the contrary  herein, a
     holder  of  Stonebridge  Options  or  Compensation  Warrants  who is a U.S.
     Resident will not be entitled to elect to receive  Exchangeable  Shares and
     any such election  otherwise  made by any such holder will be and be deemed
     to be an election to receive a TSA Class A Common Share.

(c)  Eligible Holders who have elected to receive  Exchangeable  Shares from TSA
     Exchangeco in exchange for their Class A Shares pursuant to Subsections (a)
     and (b) above,  will be entitled to make a joint income tax  election  with
     TSA  Exchangeco  pursuant  to  Section  85 of the ITA  (and  the  analogous
     provisions  of  provincial  income tax law) with respect to the transfer of
     such Class A Shares to TSA  Exchangeco  by providing a duly  completed  Tax
     election form together with any required supporting  schedules,  signed and
     forwarded  by the  Eligible  Holders to MDL on or before  the Tax  Election
     Deadline, all as provided for in the Proxy Materials.  Thereafter,  subject
     to the election forms and other documents  complying with the provisions of
     the ITA (or applicable provincial income tax law), the forms will be signed
     by  TSA  Exchangeco  and  forwarded  by  mail  to  the  appropriate  Taxing
     Authority,  with a copy thereof to the Eligible  Holder all as provided for
     in the Proxy Materials.

2.4      Adjustments to Exchange Ratio Prior to Effective Date

         If, after the Exchange Ratio has been set but prior to the Effective
         Time, TSA recapitalizes its outstanding capital stock through a
         subdivision of its outstanding shares into a greater number of shares,
         or a combination of its outstanding shares into a lesser number of
         shares, or reorganizes, reclassifies or otherwise changes its
         outstanding shares into the same or a different number of shares of
         other classes, or declares a dividend on its outstanding shares payable
         in shares of its capital stock or securities convertible into shares of
         its capital stock, or completes a rights offering for TSA Class A
         Common Shares solely to its existing shareholders at a price less than
         market price, or grants a material option solely to existing
         shareholders to acquire any TSA Class A Common Shares at a price less
         than market price and the record date for any such action is prior to
         the Effective Time, then the Exchange Ratio will be adjusted
         proportionately.

     (as modified by the Interim Order) and this Section 3.1 in connection  with
     the Arrangement  provided that,  notwithstanding  Subsection  184(5) of the
     ABCA, the written  objection to the Arrangement  resolution  referred to in
     Subsection  184(5) of the ABCA must be  received by MDL not later than 5:00
     p.m.  (Edmonton,  Alberta  time)  on the  Business  Day  preceding  the MDL
     Securityholders' Meeting and MDL Shareholders who duly exercise such rights
     of dissent and who:

     (i)  Are ultimately entitled to be paid fair value for their Class A Shares
          shall be deemed  to have  transferred  such  Class A Shares to MDL for
          cancellation on the Effective Date; or

     (ii) Are ultimately not entitled, for any reason, to be paid the fair value
          for their Class A Shares,  shall be deemed to have participated in the
          Arrangement on the same basis as any non-dissenting MDL Shareholder.

          In either case, MDL, TSA Exchangeco,  TSA Holdings or TSA shall not be
          required to recognize  such holders as MDL  Shareholders  on and after
          the  Effective  Date,  and the names of such persons  shall be deleted
          from the register of MDL Shareholders on the Effective Date.

(b)  In connection with payment to an MDL Shareholder of fair value for such MDL
     Shareholder's  Class A  Shares  upon  exercise  of such  MDL  Shareholders'
     dissent  rights,  MDL shall be  entitled  to deduct and  withhold  from any
     consideration  otherwise  payable to any such holder such amounts as MDL is
     required or permitted  to deduct and withhold  with respect to such payment
     under the ITA or any other  provision of applicable Tax Law;  provided that
     such withheld  amount shall not be remitted  prior to two (2) Business Days
     prior to the date  such  amount  is  required  by Law to be  remitted  (the
     "Remittance  Date") and where  certificates  issued pursuant to Subsections
     116(2) or 116(4) of the ITA are delivered  prior to such  Remittance  Date,
     such withheld  amount shall be released to such holder except to the extent
     that amounts were not withheld or deducted pursuant to another provision of
     applicable  Tax Law.  To the extent  that  amounts  are so  withheld,  such
     withheld  amounts  shall be treated for all purposes  hereof as having been
     paid to the holder of the Class A Shares in respect of which such deduction
     and withholding was made,  provided that such withheld amounts are actually
     remitted to the appropriate  Taxing Authority and a receipt evidencing such
     remittance is delivered to such holder.

              ARTICLE 4         CERTIFICATES AND FRACTIONAL SHARES

4.1      Exchange of Certificates for TSA Class A Common Shares

At or promptly after the Effective Time, TSA Exchangeco shall deposit with the
Depositary, for the benefit of the holders of Class A Shares transferred
pursuant to Subsection 2.2(d), certificates representing that whole number of
TSA Class A Common Shares to be delivered pursuant to Subsection 2.2(d). Upon
surrender to the Depositary of a certificate which immediately prior to the
Effective Time represented outstanding Class A Shares that were transferred to
TSA Exchangeco in exchange for TSA Class A Common Shares, together with such
other documents and instruments as would have been required to effect a transfer
of the shares formerly represented by such certificate under the ABCA and the
by-laws of MDL and such additional documents and instruments as the Depositary
may reasonably require (including a declaration of residency for the purposes of
income Tax), the holder of such surrendered certificate shall be entitled to
receive from TSA Exchangeco in exchange therefor, and the Depositary shall
deliver (a) to the Escrow Agent, twenty percent (20%) of the TSA Class A Common
Shares issuable to such holder at the Effective Time, to be held and distributed
in accordance with the terms of the Escrow Agreement and (b) to such holder, the
balance of the TSA Elected Share Consideration and Additional Consideration. In
the event of a transfer of ownership of Class A Shares that is not registered in
the transfer records of MDL, a certificate representing the proper number of TSA
Class A Common Shares may be issued to the transferee if the certificate
representing such Class A Shares is presented to the Depositary, accompanied by
all documents required to evidence and effect such transfer. Until surrendered
as contemplated by this Section 4.1, each certificate which immediately prior to
the Effective Time represented outstanding Class A Shares that were transferred
to TSA Exchangeco in exchange for TSA Class A Common Shares shall be deemed at
any time after the Effective Time, subject to Section 4.6 (Extinguishment of
Rights), to represent only the right to receive upon such surrender the TSA
Elected Share Consideration.

4.2      Issuance of Certificates Representing Exchangeable Shares

At or promptly after the Effective Time, TSA Exchangeco shall deposit with the
Depositary, for the benefit of the holders of Class A Shares transferred to TSA
Exchangeco pursuant to Subsection 2.2(e), certificates representing the whole
number of Exchangeable Shares issued pursuant to Subsection 2.2(e). Upon
surrender to the Depositary of a certificate which immediately prior to the
Effective Time represented outstanding Class A Shares that were transferred to
TSA Exchangeco in exchange for Exchangeable Shares, together with such other
documents and instruments as would have been required to effect a transfer of
the shares formerly represented by such certificate under the ABCA and the
by-laws of MDL and such additional documents and instruments as the Depositary
may reasonably require (including a declaration of residency for the purposes of
income Tax), the holder of such surrendered certificate shall be entitled to
receive from TSA Exchangeco in exchange therefor, and the Depositary shall
deliver (a) to the Escrow Agent, twenty percent (20%) of the Exchangeable Shares
issuable to such holder at the Effective Time, to be held and distributed in
accordance with the terms of the Escrow Agreement and (b) to such holder, the
balance of the Exchangeable Elected Share Consideration. In the event of a
transfer of ownership of Class A Shares that is not registered in the transfer
records of MDL, a certificate representing the proper number of Exchangeable
Shares may be issued to the transferee if the certificate representing such
Class A Shares is presented to the Depositary, accompanied by all documents
required to evidence and effect such transfer. Until surrendered as contemplated
by this Section 4.2, each certificate which immediately prior to the Effective
Time represented outstanding Class A Shares that were transferred to TSA
Exchangeco in exchange for Exchangeable Shares shall be deemed at any time after
the Effective Time, subject to Section 4.6 (Extinguishment of Rights), to
represent only the right to receive upon such surrender the Exchangeable Elected
Share Consideration.

4.3      Distributions With Respect to Unsurrendered Certificates

No dividends or other distributions declared or made after the Effective Time
with respect to Exchangeable Shares or TSA Class A Common Shares with a record
date after the Effective Time shall be paid to the holder of any unsurrendered
certificate which, immediately prior to the Effective Time, represented
outstanding Class A Shares that were exchanged pursuant to Subsection 2.2(d) or
2.2(e), and no interest will be earned or payable on these proceeds unless and
until such certificate shall be surrendered in accordance with Section 4.1 or
4.2. Subject to applicable Law and to Section 4.6 (Extinguishment of Rights), at
the time of such surrender of any such certificate (or, in the case of clause
(iii) below, at the appropriate payment date), there shall be paid to the record
holder of the certificates representing whole Exchangeable Shares or TSA Class A
Common Shares, as the case may be, without interest, (i) the amount of any
dividends or other distributions with a record date after the Effective Time
theretofore paid with respect to such whole Exchangeable Shares or TSA Class A
Common Shares, as the case may be, and (ii) the amount of dividends or other
distributions with a record date after the Effective Time but prior to surrender
and a payment date subsequent to surrender payable with respect to such whole
Exchangeable Shares or TSA Class A Common Shares, as the case may be.

4.4      No Fractional Shares

No certificates representing fractional Exchangeable Shares or TSA Class A
Common Shares, as the case may be, shall be issued pursuant to Section 4.1 or
4.2 and no dividend, stock split or other change in the capital structure of TSA
Exchangeco shall relate to any such fractional security and such fractional
interests shall not entitle the owner thereof to vote or to exercise any rights
as a security holder of MDL, TSA Exchangeco or TSA, as the case may be. In the
event that the calculation of a person's entitlement to Exchangeable Shares or
TSA Class A Common Shares pursuant to Subsection 2.2(d), 2.2(e) or 2.2(f)
results in an entitlement to a fractional interest in an Exchangeable Share or
TSA Class A Common Shares, as the case may be, then the number of Exchangeable
Shares or TSA Class A Common Shares to which such person is entitled will be
rounded down to the nearest whole number of Exchangeable Shares or TSA Class A
Common Shares, as the case may be.

4.5      Lost Certificates

If any certificate which immediately prior to the Effective Time represented
outstanding Class A Shares that were exchanged pursuant to Subsection 2.2(d) or
2.2(e) 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, the Exchangeable Elected Share Consideration or TSA
Elected Share Consideration deliverable in accordance with such holder's Letter
of Transmittal and Election Form. When authorizing such payment in exchange for
any lost, stolen or destroyed certificate, the Person to whom certificates are
to be issued shall, as a condition precedent to the issuance thereof, give a
bond satisfactory to TSA Exchangeco or TSA and their respective transfer agents,
as the case may be, in such sum as TSA Exchangeco or TSA may direct, or
otherwise indemnify TSA Exchangeco or TSA and their respective transfer agents
against any claim that may be made against MDL, TSA Exchangeco or TSA or their
respective transfer agents with respect to the certificate alleged to have been
lost, stolen or destroyed.

4.6      Extinguishment of Rights

(a)  Any certificate  which  immediately prior to the Effective Time represented
     outstanding  Class A Shares  that were  exchanged  pursuant  to  Subsection
     2.2(d) and has not been deposited,  with all other instruments  required by
     Section 4.1 (Exchange of Certificates for TSA Class A Common Shares), on or
     prior  to the  sixth  anniversary  of the  Effective  Date  shall  cease to
     represent   a  claim  or   interest   of  any  kind  or  nature  as  a  MDL
     Securityholder.  On such date,  the TSA Class A Common  Shares to which the
     former  registered  holder of the certificate  referred to in the preceding
     sentence was ultimately  entitled shall be deemed to have been  surrendered
     to  TSA   Exchangeco   together   with  all   entitlements   to  dividends,
     distributions  and interests thereon held for such former registered holder
     for no consideration.

(b)  Any certificate  which  immediately prior to the Effective Time represented
     outstanding  Class A Shares  that were  exchanged  pursuant  to  Subsection
     2.2(e) and has not been deposited,  with all other instruments  required by
     Section 4.2 (Issuance of Certificates Representing Exchangeable Shares), on
     or prior to the earlier  of: (i) the first  anniversary  of the  Redemption
     Date or  Liquidation  Date or (ii) the sixth  anniversary  of the Effective
     Date, shall cease to represent a claim or interest of any kind or nature as
     a MDL  Securityholder.  On such date, the Exchangeable  Shares to which the
     former  registered  holder of the certificate  referred to in the preceding
     sentence was ultimately  entitled shall be deemed to have been  surrendered
     to  TSA   Exchangeco   together   with  all   entitlements   to  dividends,
     distributions  and interests thereon held for such former registered holder
     for no consideration.

In either case, none of TSA, TSA Holdco, TSA Exchangeco,  MDL and the Depositary
shall be liable to any  person in  respect  of any TSA Class A Common  Shares or
Exchangeable  Shares  (or  dividends,  distributions  and  interest  in  respect
thereof)  delivered to a public  official  pursuant to any applicable  abandoned
property, escheat or similar Law.

4.7      Withholding Rights

Each Person who holds, or has a right to hold, a MDL Security at or immediately
prior to the Effective Date, shall deliver to MDL or its designee, at or before
the Effective Date:

(a)  a  certificate  confirming  that  such  MDL  Securityholder  is a  Canadian
     Resident; or

(b)  in the  case of a MDL  Securityholder  who is not a  Canadian  Resident,  a
     certificate  satisfactory  to  TSA  Exchangeco  acting  reasonably,  issued
     pursuant to Subsection  116(2) of the ITA, with respect to the MDL Security
     exchanged or disposed of, having as the "certificate  limit", as defined in
     Subsection  116(2)  of the ITA,  an amount no less than the cost of the MDL
     Security  (which may be equal to the fair market value of the  Exchangeable
     Shares  or TSA  Class A Common  Shares,  as the  case may be,  and any cash
     receivable by such MDL Securityholder) to TSA Exchangeco.

In the case of a holder of a MDL Security who is a partnership, the holder shall
also provide a certificate confirming the name and address of each member
thereof and the percentage of partnership interest held by each member.

In the event that a holder of a MDL Security fails to deliver one of the
requisite certificates described above at or before the exchange or disposition
of such MDL Security, TSA Exchangeco shall be entitled to deduct and withhold
from any consideration otherwise payable to any such holder such amounts as TSA
Exchangeco is required to deduct and withhold with respect to such payment under
the ITA or any other provision of applicable Tax Law; provided that such
withheld amount shall not be remitted prior to two (2) Business Days prior to
the date such amount is required by Law to be remitted (the "Remittance Date")
and where such certificate, or a certificate issued pursuant to Subsection
116(4) satisfactory to TSA Exchangeco, acting reasonably, is delivered prior to
such Remittance Date, such withheld amount shall be released to such holder
except to the extent that amounts were withheld or deducted pursuant to another
provision of applicable Tax Law. To the extent that amounts are so withheld,
such withheld amounts shall be treated for all purposes hereof as having been
paid to such holder of the MDL Security in respect of which such deduction and
withholding was made provided that such withheld amounts are actually remitted
to the appropriate Taxing Authority and a receipt evidencing such remittance is
delivered to such holder. To the extent that the amount so required to be
deducted or withheld from any payment to a holder exceeds the cash portion of
the consideration otherwise payable to such holder, TSA Exchangeco, as agent for
such holder, is hereby authorized to sell or otherwise dispose of such portion
of the consideration as is necessary to provide sufficient funds to TSA
Exchangeco to enable it to comply with such deduction or withholding requirement
and TSA Exchangeco shall notify such holder thereof and remit any unapplied
balance of the net proceeds of such sale. If the proceeds of such sale are
insufficient to fund the required withholding, such holder shall forthwith pay
the deficiency to TSA Exchangeco or remit same to the applicable Taxing
Authority. Such holder shall bear all reasonable costs and expenses associated
with any sale by TSA Exchangeco pursuant to the two immediately preceding
sentences.

With the necessary changes, the requirements in this Section 4.7 shall apply
upon the conversion and exchange of any Stonebridge Options or Compensation
Warrants for Class A Shares, upon the exchange of Class A Shares for TSA Class A
Common Shares, upon the exchange of Class A Shares for Exchangeable Shares and,
with delivery to TSA Exchangeco or its designee, upon the exchange of
Exchangeable Shares for TSA Class A Common Shares.

4.8      Stamp or other Transfer Taxes

Pursuant to the terms of Section 5.8 of the Voting and Exchange Trust Agreement,
a holder of Exchangeable Shares or TSA Class A Common Shares, as the case may
be, shall also 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 the TSA Class A Common Shares to a Person other than
such holder.

      ARTICLE 5       CERTAIN RIGHTS OF TSA TO ACQUIRE EXCHANGEABLE SHARES

5.1      TSA Liquidation Call Right

(a)  TSA shall have the overriding right (the "Liquidation Call Right"),  in the
     event of and  notwithstanding  the  proposed  liquidation,  dissolution  or
     winding-up of TSA Exchangeco or any other distribution of the assets of TSA
     Exchangeco for the purposes of winding-up its affairs pursuant to Article 5
     of the  Exchangeable  Share  Provisions,  to purchase from all but not less
     than all of the  holders of  Exchangeable  Shares  (other  than TSA and its
     Affiliates)  on the  Liquidation  Date  all but not  less  than  all of the
     Exchangeable Shares held by each such holder on payment by TSA of an amount
     per share  equal to:  (i) the  Current  Market  Price  (as  defined  in the
     Exchangeable  Share Provisions) of one TSA Class A Common Share on the last
     Business  Day prior to the  Liquidation  Date,  which shall be satisfied in
     full by TSA  delivering  or causing to be  delivered to such holder one TSA
     Class A Common Share (subject to any  Equivalent  Ratio  Adjustment),  plus
     (ii)  the  Dividend   Amount;   plus  (iii)  the  Fractional  Share  Amount
     (collectively the "Liquidation  Call Purchase Price") without interest.  In
     the event of the exercise of the Liquidation Call Right by TSA, each holder
     shall be  obligated  to sell  all of the  Exchangeable  Shares  held by the
     holder to TSA on the  Liquidation  Date on  payment by TSA to the holder of
     the Liquidation Call Purchase Price for each such share;

(b)  To exercise the Liquidation  Call Right, TSA must notify the Transfer Agent
     in  writing,  as agent for the  holders  of  Exchangeable  Shares,  and TSA
     Exchangeco  of TSA's  intention to exercise such right at least thirty (30)
     Business  Days  before  the  Liquidation  Date in the  case of a  voluntary
     liquidation,  dissolution or winding up of TSA Exchangeco and at least five
     (5) Business Days before the Liquidation Date in the case of an involuntary
     liquidation,  dissolution or winding up of TSA Exchangeco.  TSA will notify
     the  Transfer  Agent  accordingly  if it does not  intend to  exercise  the
     Liquidation  Call  Right.  The  Transfer  Agent will  notify the holders of
     Exchangeable  Shares as to whether or not TSA has exercised the Liquidation
     Call Right  forthwith after the expiry of the date by which the same may be
     exercised  by TSA. If TSA  exercises  the  Liquidation  Call Right,  on the
     Liquidation  Date,  TSA will  purchase and the holders will sell all of the
     Exchangeable  Shares  then  outstanding  for a price per share equal to the
     Liquidation Call Purchase Price;

(c)  Prior to the Liquidation Date, each holder of Exchangeable Shares
                  shall deliver to TSA:

     (i)  a certificate confirming that such holder is a Canadian Resident; or

     (ii) in the case of a holder who is not a Canadian Resident,  a certificate
          satisfactory to TSA acting  reasonably,  issued pursuant to Subsection
          116(2) of the ITA, with respect to the  Exchangeable  Shares exchanged
          or  disposed  of,  having as the  "certificate  limit",  as defined in
          Subsection  116(2) of the ITA,  an amount no less than the cost of the
          Exchangeable  Shares  (which may be equal to the fair market  value of
          the TSA Class A Common  Shares and any cash  receivable by such holder
          of Exchangeable Shares) to TSA or TSA Holdco, as the case may be.

     In the case of a holder who is a partnership, the holder shall also provide
     a certificate  confirming  the name and address of each member  thereof and
     the percentage of partnership interest held by each member.

     In  the  event  that a  holder  fails  to  deliver  one  of  the  requisite
     certificates  described above at or before the Liquidation  Date or, if TSA
     is  required  to  deduct  or  withhold  any  amount  pursuant  to any other
     provision  of  applicable  Tax Law,  TSA shall be  entitled  to deduct  and
     withhold from any  consideration  otherwise payable to any such holder such
     amounts  and by such means as set out in Section 4.7  (Withholding  Rights)
     above;

     (d)  For the purposes of completing the purchase of the Exchangeable Shares
          pursuant to the  Liquidation  Call Right,  TSA shall  deposit with the
          Transfer  Agent,  on or  before  the  Liquidation  Date,  certificates
          representing  the  aggregate  number  of TSA  Class  A  Common  Shares
          deliverable by TSA in partial  satisfaction  of the total  Liquidation
          Call  Purchase  Price and a cheque  or  cheques  in the  amount of the
          remaining  portion,  if any, of the total  Liquidation  Call  Purchase
          Price  without  interest.  Provided  that the total  Liquidation  Call
          Purchase  Price  has been so  deposited  with the  Transfer  Agent (or
          withheld  pursuant to  paragraph  (c) and  Section 4.7 above),  on and
          after the  Liquidation  Date the rights of each holder of Exchangeable
          Shares will be limited to receiving such holder's  proportionate  part
          of the total  Liquidation  Call Purchase  Price payable by TSA without
          interest upon presentation and surrender by the holder of certificates
          representing the Exchangeable  Shares held by such holder.  The holder
          shall on and after the  Liquidation  Date be considered and deemed for
          all  purposes  to be the  holder  of the  TSA  Class A  Common  Shares
          delivered to it. 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 NSCA and the memorandum and
          articles  of  association  of  TSA  Exchangeco  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 TSA shall  deliver  to such  holder,  certificates
          representing  the TSA Class A Common  Shares  to which  the  holder is
          entitled  and a cheque or cheques of TSA  payable at par at any branch
          of the bankers of TSA in payment of the remaining portion,  if any, of
          the total  Liquidation  Call Purchase  Price. If TSA 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  Amount
          otherwise   payable  by  TSA   Exchangeco  in   connection   with  the
          liquidation,  dissolution or winding-up of TSA Exchangeco  pursuant to
          Article 5 of the Exchangeable Share Provisions.

5.2      TSA Redemption Call Right

     (a)  TSA shall have the  overriding  right (the  "Redemption  Call Right"),
          notwithstanding  the proposed redemption of the Exchangeable Shares by
          TSA  Exchangeco  pursuant  to  Article  7 of  the  Exchangeable  Share
          Provisions,  to purchase from all but not less than all of the holders
          of  Exchangeable  Shares  (other than TSA and its  Affiliates)  on the
          Redemption Date all but not less than all of the  Exchangeable  Shares
          held by each such  holder on payment by TSA to the holder of an amount
          per share  equal to (i) the  Current  Market  Price (as defined in the
          Exchangeable  Share Provisions) of one TSA Class A Common Share on the
          last  Business  Day  prior  to the  Redemption  Date  which  shall  be
          satisfied  in full by causing to be  delivered  to such holder one TSA
          Class A Common  Share  (subject to any  Equivalent  Ratio  Adjustment)
          plus; (ii) the Dividend Amount, plus (iii) the Fractional Share Amount
          (collectively the "Redemption Call Purchase  Price").  In the event of
          the exercise of the Redemption Call Right by TSA, each holder shall be
          obligated to sell all of the Exchangeable Shares held by the holder to
          TSA on the  Redemption  Date on  payment  by TSA to the  holder of the
          Redemption Call Purchase Price for each such share.

     (b)  To exercise the  Redemption  Call Right,  TSA must notify the Transfer
          Agent in writing, as agent for the holders of Exchangeable Shares, and
          TSA  Exchangeco  of TSA's  intention  to exercise  such right at least
          forty (40) Business  Days before the  Redemption  Date,  except in the
          case  of  a  redemption  occurring  as  a  result  of  a  TSA  Control
          Transaction,  a TSA Spin-Out  Decision  Date,  an  Exchangeable  Share
          Voting Event or an Exempt  Exchangeable  Share Voting Event,  in which
          case TSA shall so notify the Transfer  Agent and TSA  Exchangeco on or
          before the Redemption Date. The Transfer Agent will notify the holders
          of the Exchangeable  Shares as to whether or not TSA has exercised the
          Redemption  Call Right  forthwith after the date by which the same may
          be exercised by TSA. If TSA exercises the  Redemption  Call Right,  on
          the  Redemption  Date, TSA will purchase and the holders will sell all
          of the  Exchangeable  Shares  then  outstanding  for a price per share
          equal to the Redemption Call Purchase Price;

     (c)  Prior to the Redemption Date, each holder of Exchangeable Shares shall
          deliver to TSA:

          (i)  a certificate confirming that such holder is a Canadian Resident;
               or

          (ii) in the  case of a  holder  who is a not a  Canadian  Resident,  a
               certificate  satisfactory  to the  purchaser  acting  reasonably,
               issued pursuant to Subsection  116(2) of the ITA, with respect to
               the  Exchangeable  Shares  exchanged or disposed of a certificate
               under  Subsection  116(2) of the ITA  having as the  "certificate
               limit",  as defined in Subsection 116(2) of the ITA, an amount no
               less than the cost of the Exchangeable Shares (which may be equal
               to the fair market value of the TSA Class A Common Shares and any
               cash receivable by such holder of Exchangeable  Shares) to TSA or
               TSA Holdco, as the case may be.

     In the case of a holder who is a partnership, the holder shall also provide
     a certificate  confirming  the name and address of each member  thereof and
     the percentage of partnership interest held by each member.

     In  the  event  that a  holder  fails  to  deliver  one  of  the  requisite

     limited  to  receiving  such  holder's  proportionate  part  of  the  total
     Redemption  Call  Purchase  Price  payable  by TSA  upon  presentation  and

     representing  the TSA Class A Common Shares to which the holder is entitled
     and a cheque or cheques of TSA  payable at par at any branch of the bankers
     of TSA in payment of the remaining portion, if any, of the total Redemption

     Exchangeable  Shares will be entitled to receive in exchange  therefor  the
     redemption price otherwise payable by TSA Exchangeco in connection with the
     redemption  of  the  Exchangeable  Shares  pursuant  to  Article  7 of  the

Notwithstanding the foregoing, this resale restriction shall not restrict TSA,
TSA Holdco, TSA Exchangeco or the Depositary from selling any TSA Class A Common

     Securityholders  Voting  Agreement)  under  the  Principal  Securityholders
     Voting Agreement);

     of the Escrow  Agreement,  covenants and agrees to pay any and all fees and
     expenses  of MDL  (including  the  fees  and  expenses  of  legal  counsel,
     accountants  and  investment  bankers)  incurred by MDL with respect to the
     fees  accrued  relating  to the  Combination  Agreement  and  this  Plan of

     for and in respect of any and all Losses paid,  suffered or incurred by, an
     Indemnitee  and  resulting  from,  caused  by,  or  arising  out of (i) the
     inaccuracy or breach of any  representation or warranty of MDL contained in
     or made pursuant to the Combination Agreement (including the MDL Disclosure
     Letter referenced therein), or in any certificate furnished by MDL pursuant
     to the  Combination  Agreement  at  Closing,  or the failure to perform any
     covenant or agreement of MDL made in the Combination Agreement; or (ii) the
     failure of the Indemnifying Shareholders to pay Excess Transaction Fees.

(d)  For  greater  certainty,  any Loss  shall  include an  interest  component,
     calculated at a floating rate equal to the prime rate of interest announced
     from time to time by Wells Fargo Bank Minnesota, NA, accruing from the date
     of actual payment or other  realization by an Indemnitee of a Loss which is
     ultimately  determined  to be subject to  indemnification  pursuant to this
     Agreement,  until the date of determination of the Recovery Amount (as such
     term is defined in the Escrow Agreement) in respect of such Loss.

(e)  The Indemnitees' sole remedy for such  indemnification  by the Indemnifying
     Shareholders is as set out herein and in the Escrow Agreement.

(d) an Exempt Exchangeable Share Voting Event is proposed and the holders of the Exchangeable Shares (other than TSA and its Affiliates) fail to take the necessary action at a meeting or by other resolution or action of holders of Exchangeable Shares, to approve or disapprove, as applicable, the Exempt Exchangeable Share Voting Event, in which case the redemption date shall be the Business Day following the day on which the holders of the Exchangeable Shares failed to take such action and the Board of Directors shall give such number of days' prior written notice of such redemption to the registered holders of the Exchangeable Shares (other than TSA and its Affiliates) as the Board of Directors may determine to be reasonably practicable in such circumstances; or (e) a TSA Spin-Out Decision Date occurs in which case the Board of Directors may accelerate such redemption date as it may determine, upon such number of days' prior written notice to the registered holders of the Exchangeable Shares (other than TSA and its Affiliates) as the Board of Directors may determine, acting in good faith and in its sole discretion and with a view to permitting holders of Exchangeable Shares sufficient time to exchange their Exchangeable Shares prior to the record date for the determination of the registered holders of TSA Class A Common Shares entitled to participate in the TSA spin-out, to be reasonably practicable in such circumstances, provided, however, that the accidental failure or omission to give any notice of redemption under clauses (a), (b), (c), (d) or (e) above to less than 10% of such holders of Exchangeable Shares (other than TSA and its Affiliates) shall not affect the validity of any such redemption;

The Corporation will not pay a dividend on any shares ranking junior to the Exchangeable Shares if the Corporation is in default of any dividend obligations with respect to the Exchangeable Shares. ARTICLE 3 DIVIDENDS 3.1 A holder of an Exchangeable Share shall be entitled to receive and the Board of Directors shall, subject to applicable Law, on each TSA Dividend Declaration Date, declare a dividend on each Exchangeable Share: (a) in the case of a cash dividend declared on the TSA Class A Common Shares, in an amount in cash for each Exchangeable Share equal to the Canadian Dollar Equivalent on the Business Day immediately preceding the date of payment of the cash dividend declared on each TSA Class A Common Share; (b) in the case of a stock dividend declared on the TSA Class A Common Shares to be paid in TSA Class A Common Shares (including a stock split payable as a stock dividend), in such number of Exchangeable Shares for each Exchangeable Share as is equal to the number of TSA Class A Common Shares to be paid on each TSA Class A Common Share unless in lieu of such stock dividend the Corporation elects in its sole and absolute discretion to effect either: (i) a corresponding and contemporaneous and economically equivalent subdivision (as determined by the Board of Directors as contemplated by Section 3.5 hereof) of the outstanding Exchangeable Shares (an "Equivalent Stock Subdivision"); or (ii) an adjustment to the ratio of TSA Class A Common Shares to be received in exchange for each Exchangeable Share (an "Equivalent Ratio Adjustment") to provide a benefit to the holders of the Exchangeable Shares that is equivalent to the benefit paid to the holders of the TSA Class A Common Shares; or (c) in the case of a dividend declared on the TSA Class A Common Shares in property other than cash or TSA Class A Common Shares, in such type and amount of property for each Exchangeable Share as is the same as or economically equivalent to (to be determined by the Board of Directors as contemplated by Section 3.5 hereof) the type and amount of property declared as a dividend on each TSA Class A Common Share. Such dividends shall be paid out of money, assets or property, as applicable, of the Corporation properly applicable to the payment of dividends, or in the case of a stock dividend contemplated by Section 3.1(b), out of authorized but unissued shares of the Corporation. Notwithstanding the foregoing, a holder's right to receive a dividend pursuant to Section 3.1(c) and the Corporation's obligation to declare a dividend on the Exchangeable Shares or otherwise provide economic equivalence shall be subject to TSA's overriding right to redeem the Exchangeable Shares pursuant to the occurrence of a TSA Spin-Out Decision Date as set out in Article 7. 3.2 Cheques of the Corporation payable at any branch of the bankers of the Corporation shall be issued in respect of any cash dividends contemplated by Section 3.1 (a) hereof and the sending of such a cheque to each holder of an Exchangeable Share shall satisfy the cash dividend represented thereby unless the cheque is not paid on presentation. Certificates registered in the name of the registered holder of Exchangeable Shares shall be issued or transferred in respect of any stock dividends contemplated by Section 3.1 (b) hereof and the sending of such a certificate to each holder of an Exchangeable Share shall, absent non-receipt thereof, satisfy the stock dividend represented thereby. Such other type and amount of property in respect of any dividends contemplated by Section 3.1 (c) hereof shall be issued, distributed or transferred by the Corporation in such manner as it shall determine and the issuance, distribution or transfer thereof by the Corporation to each holder of an Exchangeable Share shall satisfy the dividend represented thereby. In all cases, any such dividends shall be subject to any reduction or adjustment for Tax required to be deducted and withheld from such dividends paid or credited by the Corporation. No holder of an Exchangeable Share shall be entitled to recover by action or other legal process against the Corporation any dividend that is represented by a cheque that has not been duly presented to the Corporation's bankers for payment or that otherwise remains unclaimed for a period of six years from the date on which such dividend was payable. 3.3 The record date for the determination of the holders of Exchangeable Shares entitled to receive payment of, and the payment date for, any dividend declared on the Exchangeable Shares under Section 3.1 hereof shall be the same dates as the record date and payment date, respectively, for the corresponding dividend declared on the TSA Class A Common Shares. The record date for the determination of the holders of Exchangeable Shares entitled to receive Exchangeable Shares in connection with any Equivalent Stock Subdivision under Subsection 3.1(b) hereof and the effective date of such Equivalent Stock Subdivision shall be the same dates as the record and payment date, respectively, for the corresponding stock dividend declared on the TSA Class A Common Shares. The effective date of the Equivalent Ratio Adjustment shall be the same date as the payment date for the corresponding stock dividend declared on the TSA Class A Common Shares. 3.4 If on any payment date for any dividend declared on the Exchangeable Shares under Section 3.1 hereof the dividend is not paid in full on all of the Exchangeable Shares then outstanding, any such dividend that remains unpaid shall be paid on a subsequent date or dates determined by the Board of Directors on which the Corporation shall have sufficient moneys, assets or property properly applicable to the payment of such dividends. 3.5 If the Board of Directors decides to provide economic equivalence pursuant to Section 3.1 hereof then the Board of Directors shall determine, in good faith and in its sole and absolute discretion (with the assistance of such reputable and qualified independent financial advisors and/or other experts as the Board of Directors may require), such economic equivalence for the purposes of Section 3.1 hereof, and each such determination shall be conclusive and binding on the Corporation and its shareholders. In making such determination, the following factors shall, without excluding other factors determined by the Board of Directors to be relevant, be considered by the Board of Directors: (a) in the case of any stock dividend or other distribution payable in TSA Class A Common Shares, the number of such shares issued in proportion to the number of TSA Class A Common Shares previously outstanding; (b) in the case of the issuance or distribution of any rights, options or warrants to subscribe for or purchase TSA Class A Common Shares (or securities exchangeable for or convertible into or carrying rights to acquire TSA Class A Common Shares), the relationship between the exercise price of each such right, option or warrant and the Current Market Price; (c) in the case of the issuance or distribution of any other form of property (including without limitation any securities of TSA of any class other than TSA Class A Common Shares, any rights, options or warrants other than those referred to in Subsection 3.5(b) above, any evidences of indebtedness of TSA or any assets of TSA), the relationship between the fair market value (as determined by the Board of Directors in the manner above contemplated) of such property to be issued or distributed with respect to each outstanding TSA Class A Common Share and the Current Market Price of a TSA Class A Common Share; (d) in the case of any subdivision, re-division or change of the then outstanding TSA Class A Common Shares into a greater number of TSA Class A Common Shares or the reduction, combination or consolidation or change of the then outstanding TSA Class A Common Shares into a lesser number of TSA Class A Common Shares or any amalgamation, merger, re-organization or other transaction effecting the TSA Class A Common Shares, the effect thereof on the then outstanding shares of TSA Class A Common Shares; and (e) 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 TSA Class A Common Shares as a result of differences between Tax Laws of Canada, the United Kingdom 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). 3.6 Except as provided in Sections 3.1 and 3.4, the holders of Exchangeable Shares shall not be entitled to receive dividends in respect thereof. ARTICLE 4 CERTAIN RESTRICTIONS 4.1 So long as any of the Exchangeable Shares are outstanding, the Corporation shall not in the circumstances described below at any time without, but may at any time with, the approval of the holders of the Exchangeable Shares given as specified in Article 10 of these share provisions: (a) pay any dividends on the Common Shares, or any other shares ranking junior to the Exchangeable Shares, other than stock dividends payable in Common Shares or such other shares ranking junior to the Exchangeable Shares, as the case may be; (b) redeem or purchase or make any capital distribution in respect of Common Shares or any other shares ranking junior to the Exchangeable Shares with respect to the payment of dividends or on any liquidation distribution; (c) redeem or purchase any other shares of the Corporation ranking equally with the Exchangeable Shares with respect to the payment of dividends or on any liquidation distribution; or (d) issue any Exchangeable Shares or any other shares of the Corporation ranking equally with, or superior to, the Exchangeable Shares other than to the holders of Exchangeable Shares in accordance with these share provisions. The restrictions in Subsections 4.1(a), (b), (c) and (d) above shall not apply if all dividends on the outstanding Exchangeable Shares corresponding to dividends declared and paid to date on the TSA Class A Common Shares have been declared and paid on the Exchangeable Shares. Nothing herein shall be interpreted to restrict the Corporation from issuing additional Common Shares. ARTICLE 5 DISTRIBUTION ON LIQUIDATION 5.1 In the event of the liquidation, dissolution or winding-up of the Corporation or any other distribution of the assets of the Corporation among its shareholders for the purpose of winding up its affairs, subject to the exercise by TSA or TSA Holdco of the Liquidation Call Right, a holder of Exchangeable Shares shall be entitled, subject to applicable Law, to receive from the assets of the Corporation in respect of each Exchangeable Share held by such holder on the effective date (the "Liquidation Date") of such liquidation, dissolution or winding-up, before or simultaneously with any distribution of any part of the assets of the Corporation among the holders of the Common Shares and before any distribution on any other shares ranking junior to the Exchangeable Shares, an amount per share equal to (i) subject to any Equivalent Ratio Adjustment, the Current Market Price of one TSA Class A Common Share on the last Business Day prior to the Liquidation Date, which shall be satisfied in full by the Corporation causing to be delivered to such holder one TSA Class A Common Share, plus (ii) the Dividend Amount; and (iii) the Fractional Share Amount (collectively the "Liquidation Amount"). In connection with payment of the Liquidation Amount, the Corporation shall be entitled to deduct and withhold from any consideration otherwise payable to any such holder such amounts as the Corporation or TSA, as the case may be, is required or permitted to deduct and withhold with respect to such payment under the ITA or any other provision of applicable Tax Law, in each case, as amended or succeeded; provided that such withheld amount shall not be remitted prior to two (2) Business Days prior to that date such amount is required by Law to be remitted (the "Remittance Date") and where certificates issued pursuant to Subsection 116(2) or 116(4) of the ITA, if applicable, are delivered prior to such Remittance Date, such withheld amount shall be released to the holder except to the extent that amounts were withheld or deducted pursuant to another provision of applicable Tax Law. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes hereof as having been paid to the holder of the Exchangeable Shares in respect of which such deduction and withholding was made, provided that such withheld amounts are actually remitted to the appropriate Taxing Authority and a receipt evidencing such remittance is delivered to such holder. 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 of the consideration otherwise payable to such holder, the Corporation or TSA, as the case may be, as agent of such holder, is hereby authorized to sell or otherwise dispose of such portion of the consideration as is necessary to provide sufficient funds to it to enable it to comply with such deduction or withholding requirement and the Corporation or TSA, as the case may be, shall notify such holder thereof and remit to such holder any unapplied balance of the net proceeds of such sale. If the proceeds of such sale are insufficient to fund the required withholding, such holder shall forthwith pay to the Corporation or TSA, as the case may be, or remit to the applicable Taxing Authority the deficiency. Such holder shall bear all reasonable costs and expenses associated with any sale by the Corporation or TSA, as the case may be, pursuant to the two immediately preceding sentences. 5.2 On or promptly after the Liquidation Date, and subject to the exercise by TSA of the Liquidation Call Right, the Corporation shall cause to be delivered to the holders of the Exchangeable Shares the Liquidation Amount for each such Exchangeable Share upon presentation and surrender 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 any applicable Law and the memorandum and articles of association of the Corporation and such additional documents and instruments as the Transfer Agent may reasonably require, at the registered office of the Corporation or at any office of the Transfer Agent as may be specified by the Corporation by notice to the holders of the Exchangeable Shares. 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 by notice to the holders of Exchangeable Shares, on behalf of the Corporation of certificates representing fully paid and non-assessable TSA Class A Common Shares and a cheque of the Corporation payable at par at any branch of the bankers of the Corporation in payment of the remaining portion, if any, of the total Liquidation Amount (less any Tax required to be deducted and withheld from the total Liquidation Amount by the Corporation without interest). 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 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 total Liquidation Amount 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 with any chartered bank or trust company in Canada. Upon such deposit being made, the rights of the holders of Exchangeable Shares after such deposit shall be limited to receiving their proportionate part of the total Liquidation Amount (less any Tax required to be deducted and withheld therefrom) without interest 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 the total Liquidation Amount, the holders of the Exchangeable Shares shall thereafter be considered and deemed for all purposes to be the holders of the TSA Class A Common Shares delivered to them. Any certificate which represented an Exchangeable Share that has not been deposited, with all other instruments required by this Section 5.2, on or prior to the first anniversary of the Liquidation Date, shall cease to represent a claim or interest of any kind or nature as a holder of an Exchangeable Share. 5.3 After the Corporation has satisfied its obligations to pay the holders of the Exchangeable Shares the Liquidation Amount per Exchangeable Share pursuant to Section 5.1 of these share provisions, such holders shall not be entitled to share in any further distribution of the assets of the Corporation. 5.4 If TSA or TSA Holdco exercise the Liquidation Call Right, the holders of Exchangeable Shares shall be obligated to transfer their Exchangeable Shares to TSA or TSA Holdco, as applicable, in accordance with the terms of the Liquidation Call Right. ARTICLE 6 RETRACTION OF EXCHANGEABLE SHARES BY HOLDER 6.1 A holder of Exchangeable Shares shall be entitled at any time, subject to the exercise by TSA of the Retraction Call Right 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 per share equal to (i) subject to any Equivalent Ratio Adjustment, the Current Market Price of a TSA Class A Common Share on the last Business Day prior to the Retraction Date, which shall be satisfied in full by the Corporation causing to be delivered to such holder one TSA Class A Common Share for each Exchangeable Share presented and surrendered by the holder, plus (ii) the Dividend Amount and (iii) the Fractional Amount (collectively the "Retraction Price"). 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 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 memorandum and articles of association 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 ten (10) Business Days nor more than fifteen (15) 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 fifteenth (15th) Business Day after the date on which the Retraction Request is received by the Corporation; (c) acknowledging the overriding right (the "Retraction Call Right") of TSA to purchase all but not fewer 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 to TSA in accordance with the Retraction Call Right on the terms and conditions set out in Section 6.3 below; and (e) stating whether the holder is a Canadian Resident or is not a Canadian Resident. 6.2 Subject to the exercise by TSA 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 6.8, 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. If only a part of the Exchangeable Shares represented by any certificate are redeemed (or purchased by TSA 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 TSA thereof and provide a copy of such Retraction Request. In order to exercise the Retraction Call Right, TSA must notify the Corporation in writing of its determination to do so (the "TSA Call Notice") within five (5) Business Days of notification to TSA by the Corporation of the receipt by the Corporation of the Retraction Request. If TSA does not so notify the Corporation within such five (5) Business Day period, the Corporation will notify the holder as soon as possible thereafter that TSA will not exercise the Retraction Call Right. If TSA delivers the TSA Call Notice within such five (5) Business Day time period, and provided that the Retraction Request is not revoked by the holder in the manner specified in Section 6.8, the Retraction Request shall thereupon be considered only to be an offer by the holder to sell the Retracted Shares to TSA in accordance with the Retraction Call Right. In such event, the Corporation shall not redeem the Retracted Shares and TSA shall purchase from such holder and such holder shall sell to TSA on the Retraction Date the Retracted Shares for a purchase price (the "Purchase Price") per share equal to the Retraction Price per share. For the purposes of completing a purchase pursuant to the Retraction Call Right, TSA shall deposit with the Transfer Agent, on or before the Retraction Date, certificates representing TSA Class A Common Shares and, if applicable, a cheque or cheques of TSA payable at par at any branch of the bankers of TSA representing the aggregate Dividend Amount less any amounts withheld on account of Tax required by Law to be deducted and withheld therefrom. Provided that TSA has complied with the immediately preceding sentence, 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 TSA does not deliver a TSA Call Notice within such five (5) Business Day period, and provided that Retraction Request is not revoked by the holder in the manner specified in Section 6.8, the Corporation shall redeem the Retracted Shares on the Retraction Date and in the manner otherwise contemplated in this Article 6. TSA shall be permitted to delegate or assign the Retraction Call Right to TSA Holdco with the result that all references to TSA in these share provisions with respect to the exercise of the Retraction Call Right in respect of which the delegation or assignment is made shall be deemed to refer to TSA Holdco. 6.4 A holder who is not a Canadian Resident shall deliver with each Retraction Request a certificate satisfactory to the Corporation or TSA, as the case may be, acting reasonably, issued pursuant to Subsection 116(2) of the ITA, with respect to the Exchangeable Shares being exchanged, having as the "certificate limit" as defined in Subsection 116(2) of the ITA, an amount no less than the cost of the Exchangeable Shares (which may be equal to the fair market value of the TSA Class A Common Shares and any cash receivable by such holder of Exchangeable Shares) to the Corporation or TSA, as the case may be. In the case of a holder who is a partnership, the holder shall also provide a certificate confirming the name and address of each member thereof and the percentage of partnership interest held by each member. In the event that a holder fails to deliver one of the requisite certificates described with such holder's Retraction Request or, if the Corporation or TSA is required to deduct or withhold any amount under any other provision of applicable Tax Law, the Corporation or TSA, as the case may be, shall be entitled to deduct and withhold from any consideration otherwise payable to any such holder such amounts as the Corporation or TSA, as the case may be, is required or permitted to deduct and withhold with respect to such payment under the ITA or any other provision of applicable Tax Law, in each case, as amended or succeeded; provided that such withheld amount shall not be remitted prior to two (2) Business Days prior to the date such amount is required by Law to be remitted (the "Remittance Date") and where such certificate or a certificate issued pursuant to Subsection 116(4) satisfactory to TSA Exchangeco, acting reasonably, is delivered prior to such Remittance Date, such withheld amount shall be released to the holder except to the extent that amounts were withheld or deducted pursuant to another provision of applicable Tax Law. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes hereof as having been paid to such holder of the Exchangeable Shares in respect of such deduction and withholding was made, provided that such withheld amounts are actually remitted to the appropriate Taxing Authority and a receipt evidencing such remittance is delivered to such holder. 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 of the consideration otherwise payable to such holder, the Corporation or TSA, as the case may be, as agent of such holder, is hereby authorized to sell or otherwise dispose of such portion of the consideration as is necessary to provide sufficient funds to it to enable it to comply with such deduction or withholding requirement and the Corporation or TSA, as the case may be, shall notify such holder thereof and remit to such holder any unapplied balance of the net proceeds of such sale. If the proceeds of such sale are insufficient to fund the required withholding, such holder shall forthwith pay to the Corporation or TSA, as the case may be, or remit to the applicable Taxing Authority the deficiency. Such holder shall bear all reasonable costs and expenses associated with any sale by the Corporation or TSA, as the case may be, pursuant to the two immediately preceding sentences. 6.5 The Corporation or TSA, 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 Corporation by notice to the holders of Exchangeable Shares, certificates representing fully paid and non-assessable TSA Class A Common Shares registered in the name of the holder or in such other name as the holder may request, and, if applicable, a cheque payable at par at any branch of the bankers of the Corporation or, as applicable, representing the aggregate Dividend Amount or Fractional Share Amount in partial satisfaction of the remaining portion of the total Retraction Price or the total Purchase Price, as the case may be, in each case, less any amounts withheld on account of Tax required to be deducted and withheld therefrom, and such delivery of such certificates and cheques on behalf of the Corporation or by TSA, as the case may be, or by 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, to the extent that the same is represented by such share certificates and cheques (plus any Tax deducted and withheld therefrom and remitted to the proper Taxing Authority without interest), unless such cheque is not paid on due presentation. 6.6 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 his proportionate part of the total Retraction Price or total Purchase Price, as 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 as provided in Section 6.5, in which case the rights of such holder shall remain unaffected until 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 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 TSA shall thereafter be considered and deemed for all purposes to be a holder of the TSA Class A Common Shares delivered to it. Any certificate which represented an Exchangeable Share that has not been deposited, with all other instruments required by this Article 6, on or prior to the sixth anniversary of the Effective Date, shall cease to represent a claim or interest of any kind or nature as a holder of an Exchangeable Share. 6.7 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 solvency requirements or other provisions of applicable Law, including, without limitation, the NSCA and United States securities Laws. If the Corporation believes that on any Retraction Date it would not be permitted by any of such provisions to redeem all the Retracted Shares tendered for redemption on such date, and provided that TSA shall not have exercised the Retraction Call Right with respect to all 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 at least two (2) Business Days 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 solvency requirements or other provisions of applicable Law, including, without limitation, the NSCA and United States securities Laws, the Corporation shall redeem the maximum number of whole Exchangeable Shares which the Board of Directors determine the Corporation is, on the Retraction Date, permitted to redeem, which shall be selected as nearly as may be pro rata (disregarding fractions) in proportion to the total number of Exchangeable Shares tendered for retraction by each holder thereof and the Corporation 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 6.8 and provided further that TSA shall not have exercised the Retraction Call Right with respect to the Retracted Shares, the holder of any such Retracted Shares not redeemed by the Corporation pursuant to Section 6.2 of these share provisions as a result of liquidity or solvency requirements or applicable Laws shall be deemed, by giving the Retraction Request, to require TSA to purchase such Retracted Shares from such holder on the Retraction Date or as soon as practicable thereafter on payment by TSA to such holder of the Purchase Price for each such Retracted Share, all as more specifically provided in the Voting and Exchange Trust Agreement. 6.8 A holder of Retracted Shares may, by notice in writing given by such 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 shall be null and void and, for greater certainty, the revocable offer constituted by the Retraction Request to sell the Retracted Shares to TSA shall be deemed to have been revoked. ARTICLE 7 REDEMPTION OF EXCHANGEABLE SHARES BY THE CORPORATION 7.1 Subject to applicable Law (including solvency restrictions which may require redemption of fewer than all of the Exchangeable Shares on a partial, pro-rata basis), and if TSA does not exercise the Redemption Call Right, the Corporation shall on the Redemption Date redeem the whole of the then outstanding Exchangeable Shares (other than those held by TSA and its Affiliates) for an amount per share equal to (i) subject to any Equivalent Ratio Adjustment, the Current Market Price of a TSA Class A Common Share on the last Business Day prior to the Redemption Date, which shall be satisfied in full by the Corporation causing to be delivered to each holder of Exchangeable Shares one TSA Class A Common Share for each Exchangeable Share held by such holder, plus (ii) the Dividend Amount plus (iii) the Fractional Share Amount (collectively the "Redemption Price"). 7.2 In any case of a redemption of Exchangeable Shares under this Article 7, the Corporation shall, at least forty (40) Business Days before the Redemption Date (other than a Redemption Date established in connection with a TSA Control Transaction, a TSA Spin-Out Decision Date, an Exchangeable Share Voting Event or an Exempt Exchangeable Share Voting Event), send or cause to be sent to each holder of Exchangeable Shares a notice in writing of the redemption by the Corporation or the purchase by TSA under the Redemption Call Right, as the case may be, of the Exchangeable Shares held by such holder. In the case of a Redemption Date established in connection with a TSA Control Transaction, a TSA Spin-Out Decision Date, an Exchangeable Share Voting Event and an Exempt Exchangeable Share Voting Event, the written notice of redemption by the Corporation or the purchase by TSA under the Redemption Call Right will be sent on or before the Redemption Date, on as many days prior written notice as may be determined by the Board of Directors of the Corporation, acting in good faith and in its sole discretion and with a view to permitting the holders of Exchangeable Shares sufficient time to exchange their Exchangeable Shares prior to the record date for determination of the registered holders of TSA Class A Common Shares in order to participate in a TSA Control Transaction or TSA Spin-Out Decision Date, to be reasonably practicable in the circumstances. In any such case, such notice shall set out the Redemption Price or the Redemption Call Purchase Price, as the case may be, the Redemption Date and, if applicable, particulars of the Redemption Call Right. 7.3 On or before the Redemption Date, a holder of Exchangeable Shares shall deliver to the Corporation a certificate stating whether the holder is a Canadian Resident or is not a Canadian Resident. On or before the Redemption Date, a holder of Exchangeable Shares who is not a Canadian Resident shall deliver to the Corporation a certificate issued pursuant to Subsection 116(2) of the ITA, with respect to the Exchangeable Shares being redeemed having as the "certificate limit" as defined in Subsection 116(2) of the ITA, an amount no less than the cost of the Exchangeable Shares (which may be equal to the fair market value of the TSA Class A Common Shares and any cash receivable by such holder) to the Corporation. In the case of a holder who is a partnership, the holder shall also provide a certificate confirming the name and address of each member thereof and the percentage of partnership interest held by each member. In the event that a holder fails to deliver one of the requisite certificates described or if the Corporation is required to deduct or withhold any amount under any other provision of applicable Tax Law, the Corporation shall be entitled to deduct and withhold from any consideration otherwise payable to any such holder such amounts as the Corporation is required or permitted to deduct and withhold with respect to such payment under the ITA or any other provision of applicable Tax Law, in each case, as amended or succeeded; provided that such withheld amount shall not be remitted prior to two (2) Business Days prior to the date such amount is required by Law to be remitted (the "Remittance Date") and where such certificate or a certificate issued pursuant to Subsection 116(4) satisfactory to the Corporation, acting reasonably, is delivered prior to such Remittance Date, such withheld amount shall be released to the holder except to the extent that amounts were withheld or deducted pursuant to another provision of applicable Tax Law. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes hereof as having been paid to such holder of the Exchangeable Shares in respect of which such deduction and withholding was made, provided that such withheld amounts are actually remitted to the appropriate Taxing Authority and a receipt evidencing such remittance is delivered to such holder. 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 of the consideration otherwise payable to such holder, the Corporation, as the case may be, as agent of such holder, is hereby authorized to sell or otherwise dispose of (or itself take title at the then-Current Market Price) such portion of the consideration as is necessary to provide sufficient funds to it to enable it to comply with such deduction or withholding requirement and the Corporation shall notify such holder thereof and remit to such holder any unapplied balance of the net proceeds of such sale. If the proceeds of such sale are insufficient to fund the required withholding, such holder shall forthwith pay to the Corporation or remit to the applicable Taxing Authority the deficiency. Such holder shall bear all reasonable costs and expenses associated with any sale by the Corporation pursuant to the two immediately preceding sentences. 7.4 On or after the Redemption Date and subject to the exercise by TSA of the Redemption Call Right, the Corporation shall cause to be delivered to the holders of the Exchangeable Shares to be redeemed 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 memorandum and articles of association of the Corporation and such additional documents and instruments as the Transfer Agent may reasonably require. 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 of the Corporation 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 such notice, on behalf of the Corporation of certificates representing fully paid and non-assessable TSA Class A Common Shares and, if applicable, a cheque of the Corporation payable at par at any branch of the bankers of the Corporation in respect of the full amount of the Dividend Amount or Fractional Share Amount comprising the total Redemption Price (less any Tax required to be deducted and withheld from the total Redemption Price by the Corporation without interest). On and after the 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 total Redemption Price, unless payment of 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 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 total Redemption Price for 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 with any chartered bank or trust company in Canada named in such notice, less any amounts withheld on account of Tax required to be deducted and withheld therefrom. Upon the later of such deposit being made and the 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 Redemption Date, as the case may be, shall be limited to receiving their proportionate part of 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 the total Redemption Price, the holders of the Exchangeable Shares shall thereafter be considered and deemed for all purposes to be holders of the TSA Class A Common Shares delivered to them. Any certificate which represented an Exchangeable Share that has not been deposited, with all other instruments required by this Section 7.4, on or prior to the first anniversary of the Redemption Date, shall cease to represent a claim or interest of any kind or nature as a holder of an Exchangeable Share. 7.5 If TSA or TSA Holdco exercises the Redemption Call Right, the holders of Exchangeable Shares shall be obligated to transfer their Exchangeable Shares to TSA or TSA Holdco, as the case may be, in accordance with the terms of the Redemption Call Right. ARTICLE 8 VOTING RIGHTS 8.1 Except as required by applicable Law and the provisions of Article 9 and Sections 10.1, 10.2 and 11.2, 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. The holders of the Exchangeable Shares shall, however, be entitled to notice of meetings of the shareholders called for the purpose of authorizing the liquidation, dissolution or winding up of the Corporation. ARTICLE 9 AMENDMENT, APPROVAL AND CONVERSION 9.1 The rights, privileges, restrictions and conditions attaching to the Exchangeable Shares may beadded to, changed or removed but 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, including without limitation the NSCA, subject to a minimum requirement that such approval be evidenced by resolution passed by not less than two-thirds of the votes cast on such resolution at a meeting of holders of Exchangeable Shares duly called and held at which the holders of at least 25% of the outstanding Exchangeable Shares at that time are present or represented by proxy (excluding Exchangeable Shares beneficially owned by TSA or an Affiliate of TSA). If at any such meeting the holders of at least 25% 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 five 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 two-thirds of the votes cast on such resolution at such meeting shall constitute the approval or consent of the holders of the Exchangeable Shares. 9.3 Notwithstanding any other provision hereof, the Corporation shall be entitled to convert at any time any outstanding Exchangeable Shares into Common Shares with the consent of the holder of such Exchangeable Shares (the "Corporation Conversion Right"). To exercise the Corporation Conversion Right, the Corporation will send a written request for the consent of a holder to convert a specified number of Exchangeable Shares into Common Shares (the "Conversion Request"), and, at a mutually agreed time, the Corporation shall convert each such Exchangeable Share held by such holder who has given his or its consent thereto for such number of Common Shares as would have an equivalent value at the time of conversion (the "Conversion Amount") upon presentation and surrender at the principal corporate office of the Corporation of the certificate(s) representing such Exchangeable Shares, together with such other documents and instruments as may be required to effect a transfer of the Exchangeable Shares under applicable Law and the memorandum and articles of association of the Corporation and such additional documents and instruments, if any, as the Corporation may reasonably require. Payment of the Conversion Amount shall be made by delivery to the consenting holder, at the address stated in the Conversion Request, of the specified number of Common Shares, which shares shall be duly issued as fully paid and non-assessable and shall be free and clear of any lien, claim or encumbrance. ARTICLE 10 RECIPROCAL CHANGES, ETC. IN RESPECT OF TSA CLASS A COMMON SHARES 10.1 Each holder of an Exchangeable Share is deemed to acknowledge that the Support Agreement provides, in part, that so long as there are Exchangeable Shares outstanding which are not held by TSA or any Affiliate of TSA, TSA will not without the prior approval of the Corporation and the prior approval of the holders of the Exchangeable Shares given in accordance with Section 9.2 of these share provisions: (a) issue or distribute TSA Class A Common Shares (or securities exchangeable for or convertible into or carrying rights to acquire TSA Class A Common Shares) to the holders of all or substantially all of the then outstanding TSA Class A Common Shares by way of stock dividend (or a stock split payable as a stock dividend) or other distribution, other than an issue of TSA Class A Common Shares (or securities exchangeable for or convertible into or carrying rights to acquire TSA Class A Common Shares) to holders of TSA Class A Common Shares who exercise an option to receive dividends in TSA Class A Common Shares (or securities exchangeable for or convertible into or carrying rights to acquire TSA Class A Common Shares) in lieu of receiving cash dividends; or (b) issue or distribute rights, options or warrants to the holders of all or substantially all of the then outstanding TSA Class A Common Shares entitling them to subscribe for or to purchase TSA Class A Common Shares (or securities exchangeable for or convertible into or carrying rights to acquire TSA Class A Common Shares); or (c) issue or distribute to the holders of all or substantially all of the then outstanding TSA Class A Common Shares: (i) shares or securities of TSA of any class other than TSA Class A Common Shares (other than shares convertible into or exchangeable for or carrying rights to acquire TSA Class A Common Shares); (ii) rights, options or warrants other than those referred to in Subsection 10.1(b) above, (iii) evidences of indebtedness of TSA; or (iv) assets of TSA; unless the Corporation or TSA is permitted under applicable Law to issue and distribute the same, or the economic equivalent on a per share basis of, such rights, options, securities, shares, evidences of indebtedness or other assets to holders of the Exchangeable Shares other than TSA and its Affiliates or to effect an Equivalent Stock Subdivision or an Equivalent Ratio Adjustment and the Corporation or TSA issues or distributes the same, or the economic equivalent of, such rights, options, securities, shares, evidences of indebtedness or other assets simultaneously to holders of the Exchangeable Shares or effect an Equivalent Stock Subdivision or an Equivalent Ratio Adjustment; provided that, for greater certainty, the above restrictions shall not: (i) apply to any securities issued or distributed by TSA in order to give effect to and to consummate the transactions contemplated by, and in accordance with, the Plan of Arrangement or (ii) restrict TSA's overriding Redemption Call Right in the event of a TSA Spin-Out Decision Date. 10.2 Each holder of an Exchangeable Share is deemed to acknowledge that the Support Agreement further provides, in part, that so long as there are Exchangeable Shares outstanding which are not held by TSA or any Affiliate of TSA, TSA will not without the prior approval of the Corporation and the prior approval of the holders of the Exchangeable Shares given in accordance with Section 9.2 of these share provisions: (a) subdivide, redivide or change the then outstanding TSA Class A Common Shares into a greater number of TSA Class A Common Shares; or (b) reduce, combine or consolidate or change the then outstanding TSA Class A Common Shares into a lesser number of TSA Class A Common Shares; or (c) reclassify or otherwise change the TSA Class A Common Shares or effect an amalgamation, merger, reorganization or other transaction affecting the TSA Class A Common Shares; unless (i) the Corporation 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 (ii) the same or an economically equivalent change is made to, or in the rights of the holders of, the Exchangeable Shares. The Support Agreement further provides, in part, that the aforesaid provisions of the Support Agreement shall not be changed without the approval of the holders of the Exchangeable Shares given in accordance with Section 9.2 of these share provisions. ARTICLE 11 ACTIONS BY THE CORPORATION UNDER THE SUPPORT AGREEMENT 11.1 The Corporation will take all such actions and do all such things as shall be necessary or advisable to perform and comply with and to ensure performance and compliance by TSA and TSA Holdco with all provisions of the Support Agreement applicable to the Corporation, TSA and TSA Holdco, respectively, in accordance with the terms thereof including, without limitation, taking all such actions and doing all such things as shall be necessary or advisable to enforce to the fullest extent possible for the direct benefit of the Corporation or the holders of Exchangeable Shares all rights and benefits in favour of the Corporation or the holders of Exchangeable Shares under or pursuant to such agreement. 11.2 The Corporation shall not propose, agree to or otherwise give effect to any amendment to, or waiver or forgiveness of its rights or obligations under, the Support Agreement without the approval of the holders of the Exchangeable Shares given in accordance with Section 9.2 of these share provisions other than such amendments, waivers and/or forgiveness as may be necessary or advisable for the purposes of: (a) adding to the covenants of any or all parties to such agreement for the protection of the Corporation or the holders of the Exchangeable Shares; (b) making such provisions or modifications not inconsistent with these Exchangeable Share Provisions as may be necessary or desirable with respect to matters or questions which, in the good faith opinion of the Board of Directors of the Corporation, it may be expedient to make, provided that such Board of Directors shall be of the good faith opinion, after consultation with counsel, that such provisions or modifications will not be prejudicial to the interests of the holders of the Exchangeable Shares; or (c) making such changes or corrections to such agreement which, on the advice of counsel to the Corporation, are reasonably required for the purpose of curing or correcting any ambiguity or defect or inconsistent provision or clerical omission or mistake or manifest error, provided that in the opinion of the Board of Directors of the Corporation, after consultation with counsel, such changes or corrections will not be prejudicial to the interests of the holders of the Exchangeable Shares. ARTICLE 12 LEGEND; CALL RIGHTS 12.1 The certificates evidencing the Exchangeable Shares shall contain or have affixed thereto a legend, in form and on terms approved by the Board of Directors, with respect to: (a) the Support Agreement; (b) the provisions of these share provisions relating to the Liquidation Call Right, the Retraction Call Right and the Redemption Call Right (a copy of which rights shall be attached to each certificate); and (c) the Voting and Exchange Trust Agreement (including the provisions with respect to the voting rights, exchange right and automatic exchange thereunder). 12.2 Each holder of an Exchangeable Share, whether of record or beneficially, by virtue of becoming and being such a holder shall be deemed to acknowledge each of the Liquidation Call Right, the Retraction Call Right and the Redemption Call Right, in each case, in favor of TSA and other permitted persons and the overriding nature thereof in connection with the liquidation, dissolution or winding-up of the Corporation or the retraction or redemption of Exchangeable Shares, as the case may be, and to be bound thereby in favor of TSA and other permitted persons as therein provided.

SCHEDULE B TO PROVISIONS ATTACHING TO EXCHANGEABLE SHARES TSA LIQUIDATION CALL RIGHT (a) TSA shall have the overriding right (the "Liquidation Call Right"), in the event of and notwithstanding the proposed liquidation, dissolution or winding-up of TSA Exchangeco or any other distribution of the assets of TSA Exchangeco for the purposes of winding-up its affairs pursuant to Article 5 of the Exchangeable Share Provisions, to purchase from all but not less than all of the holders of Exchangeable Shares (other than TSA and its Affiliates) on the Liquidation Date all but not less than all of the Exchangeable Shares held by each such holder on payment by TSA of an amount per share equal to: (i) the Current Market Price (as defined in the Exchangeable Share Provisions) of one TSA Class A Common Share on the last Business Day prior to the Liquidation Date, which shall be satisfied in full by TSA delivering or causing to be delivered to such holder one TSA Class A Common Share (subject to any Equivalent Ratio Adjustment), plus (ii) the Dividend Amount; plus (iii) the Fractional Share Amount (collectively the "Liquidation Call Purchase Price") without interest. In the event of the exercise of the Liquidation Call Right by TSA, each holder shall be obligated to sell all of the Exchangeable Shares held by the holder to TSA on the Liquidation Date on payment by TSA to the holder of the Liquidation Call Purchase Price for each such share; (b) To exercise the Liquidation Call Right, TSA must notify the Transfer Agent in writing, as agent for the holders of Exchangeable Shares, and TSA Exchangeco of TSA's intention to exercise such right at least thirty (30) Business Days before the Liquidation Date in the case of a voluntary liquidation, dissolution or winding up of TSA Exchangeco and at least five (5) Business Days before the Liquidation Date in the case of an involuntary liquidation, dissolution or winding up of TSA Exchangeco. TSA will notify the Transfer Agent accordingly if it does not intend to exercise the Liquidation Call Right. The Transfer Agent will notify the holders of Exchangeable Shares as to whether or not TSA has exercised the Liquidation Call Right forthwith after the expiry of the date by which the same may be exercised by TSA. If TSA exercises the Liquidation Call Right, on the Liquidation Date, TSA will purchase and the holders will sell all of the Exchangeable Shares then outstanding for a price per share equal to the Liquidation Call Purchase Price; (c) Prior to the Liquidation Date, each holder of Exchangeable Shares shall deliver to TSA: (i) a certificate confirming that such holder is a Canadian Resident; or (ii) in the case of a holder who is not a Canadian Resident, a certificate satisfactory to TSA acting reasonably, issued pursuant to Subsection 116(2) of the ITA, with respect to the Exchangeable Shares exchanged or disposed of, having as the "certificate limit", as defined in Subsection 116(2) of the ITA, an amount no less than the cost of the Exchangeable Shares (which may be the fair market value of the TSA Class A Common Shares and any cash receivable by such holder of Exchangeable Shares) to TSA or TSA Holdco as the case may be. In the case of a holder who is a partnership, the holder shall also provide a certificate confirming the name and address of each member thereof and the percentage of partnership interest held by each member. In the event that a holder fails to deliver one of the requisite certificates described above at or before the Liquidation Date or, if TSA is required to deduct or withhold any amount pursuant to any other provision of applicable Tax Law, TSA shall be entitled to deduct and withhold from any consideration otherwise payable to any such holder such amounts and by such means as set out in Section 4.7 (Withholding Rights) of the Plan of Arrangement; (d) For the purposes of completing the purchase of the Exchangeable Shares pursuant to the Liquidation Call Right, TSA shall deposit with the Transfer Agent, on or before the Liquidation Date, certificates representing the aggregate number of TSA Class A Common Shares deliverable by TSA in partial satisfaction of the total Liquidation Call Purchase Price and a cheque or cheques in the amount of the remaining portion, if any, of the total Liquidation Call Purchase Price without interest.

The holder shall on and after the Liquidation Date be considered and deemed for all purposes to be the holder of the TSA Class A Common Shares delivered to it. 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 NSCA and the memorandum and articles of association of TSA Exchangeco 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 TSA shall deliver to such holder, certificates representing the TSA Class A Common Shares to which the holder is entitled and a cheque or cheques of TSA payable at par at any branch of the bankers of TSA in payment of the remaining portion, if any, of the total Liquidation Call Purchase Price. If TSA 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 Amount otherwise payable by TSA Exchangeco in connection with the liquidation, dissolution or winding-up of TSA Exchangeco pursuant to Article 5 of the Exchangeable Share Provisions.

SCHEDULE C TO PROVISIONS ATTACHING TO EXCHANGEABLE SHARES TSA REDEMPTION CALL RIGHT (a) TSA shall have the overriding right (the "Redemption Call Right"), notwithstanding the proposed redemption of the Exchangeable Shares by TSA Exchangeco pursuant to Article 7 of the Exchangeable Share Provisions, to purchase from all but not less than all of the holders of Exchangeable Shares (other than TSA and its Affiliates) on the Redemption Date all but not less than all of the Exchangeable Shares held by each such holder on payment by TSA to the holder of an amount per share equal to (i) the Current Market Price (as defined in the Exchangeable Share Provisions) of one TSA Class A Common Share on the last Business Day prior to the Redemption Date which shall be satisfied in full by causing to be delivered to such holder one TSA Class A Common Share (subject to any Equivalent Ratio Adjustment) plus; (ii) the Dividend Amount, plus (iii) the Fractional Share Amount (collectively the "Redemption Call Purchase Price"). In the event of the exercise of the Redemption Call Right by TSA, each holder shall be obligated to sell all of the Exchangeable Shares held by the holder to TSA on the Redemption Date on payment by TSA to the holder of the Redemption Call Purchase Price for each such share. (b) To exercise the Redemption Call Right, TSA must notify the Transfer Agent in writing, as agent for the holders of Exchangeable Shares, and TSA Exchangeco of TSA's intention to exercise such right at least forty (40) Business Days before the Redemption Date, except in the case of a redemption occurring as a result of a TSA Control Transaction, a TSA Spin-Out Decision Date, an Exchangeable Share Voting Event or an Exempt Exchangeable Share Voting Event, in which case TSA shall so notify the Transfer Agent and TSA Exchangeco on or before the Redemption Date. The Transfer Agent will notify the holders of the Exchangeable Shares as to whether or not TSA has exercised the Redemption Call Right forthwith after the date by which the same may be exercised by TSA. If TSA exercises the Redemption Call Right, on the Redemption Date, TSA will purchase and the holders will sell all of the Exchangeable Shares then outstanding for a price per share equal to the Redemption Call Purchase Price; (c) Prior to the Redemption Date, each holder of Exchangeable Shares shall deliver to TSA: (i) a certificate confirming that such holder is a Canadian Resident; or (ii) in the case of a holder who is a not a Canadian Resident, a certificate satisfactory to the purchaser acting reasonably, issued pursuant to Subsection 116(2) of the ITA, with respect to the Exchangeable Shares exchanged or disposed of a certificate under Subsection 116(2) of the ITA having as the "certificate limit", as defined in Subsection 116(2) of the ITA, an amount no less than the cost of the Exchangeable Shares (which may be the fair market value of the TSA Class A Common Shares and any cash receivable by such holder of Exchangeable Shares) to TSA or TSA Holdco, as the case may be. In the case of a holder who is a partnership, the holder shall also provide a certificate confirming the name and address of each member thereof and the percentage of partnership interest held by each member. In the event that a holder fails to deliver one of the requisite certificates described above or, if TSA is required to deduct or withhold any other amount pursuant to any provision of applicable Tax Law, at or before the Redemption Date, TSA shall be entitled to deduct and withhold from any consideration otherwise payable to any such holder such amounts and by such means as set out in Section 4.7 (Withholding Rights) of the Plan of Arrangement; (d) For the purposes of completing the purchase of the Exchangeable Shares pursuant to the Redemption Call Right, TSA shall deposit with the Transfer Agent, on or before the Redemption Date, certificates representing the aggregate number of TSA Class A Common Shares deliverable by TSA in partial satisfaction of the total Redemption Call Purchase Price and a cheque or cheques in the amount of the remaining portion, if any, of the total Redemption Call Purchase Price. Provided that the total Redemption Call Purchase Price has been so deposited with the Transfer Agent (or withheld pursuant to paragraph (c) above), on and after the 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 TSA upon presentation and surrender by the holder of certificates representing the Exchangeable Shares held by such holder. The holder shall on and after the Redemption Date be considered and deemed for all purposes to be the holder of the TSA Class A Common Shares delivered to such holder without interest. 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 NSCA and the memorandum and articles of association of TSA Exchangeco 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 TSA shall deliver to such holder, certificates representing the TSA Class A Common Shares to which the holder is entitled and a cheque or cheques of TSA payable at par at any branch of the bankers of TSA in payment of the remaining portion, if any, of the total Redemption Call Purchase Price. If TSA does not exercise the Redemption Call Right in the manner described above, on the Redemption Date the holders of the Exchangeable Shares will be entitled to receive in exchange therefor the redemption price otherwise payable by TSA Exchangeco in connection with the redemption of the Exchangeable Shares pursuant to Article 7 of the Exchangeable Share Provisions.

TSA will prepare and file the Registration Statement (as defined in the Combination Agreement) with the SEC. 2.7 Economic Equivalence So long as any Exchangeable Shares not owned by TSA or its Affiliates are outstanding: (a) TSA will not without the prior approval of TSA Exchangeco and the prior approval of the holders of the Exchangeable Shares given in accordance with Section 9.2 of the Exchangeable Share Provisions: (i) issue or distribute TSA Class A Common Shares (or securities exchangeable for or convertible into or carrying rights to acquire TSA Class A Common Shares) to the holders of all or substantially all of the then outstanding TSA Class A Common Shares by way of stock dividend (including a stock split payable as a stock dividend) or other distribution, other than an issue of TSA Class A Common Shares (or securities exchangeable for or convertible into or carrying rights to acquire TSA Class A Common Shares) to holders of TSA Class A Common Shares who exercise an option to receive dividends in TSA Class A Common Shares (or securities exchangeable for or convertible into or carrying rights to acquire TSA Class A Common Shares) in lieu of receiving cash dividends; (ii) issue or distribute rights, options or warrants to the holders of all or substantially all of the then outstanding TSA Class A Common Shares entitling them to subscribe for or to purchase TSA Class A Common Shares (or securities exchangeable for or convertible into or carrying rights to acquire TSA Class A Common Shares); or (iii) issue or distribute to the holders of all or substantially all of the then outstanding TSA Class A Common Shares: (A) shares or securities of TSA of any class other than TSA Class A Common Shares (other than shares convertible into or exchangeable for or carrying rights to acquire TSA Class A Common Shares); (B) rights, options or warrants other than those referred to in Section 2.7(a)(ii) above; (C) evidences of indebtedness of TSA; or (D) assets of TSA; unless TSA or TSA Exchangeco is permitted under applicable Law to issue or distribute the same, or the economic equivalent on a per share basis of, such rights, options, securities, shares, evidences of indebtedness or other assets to holders of the Exchangeable Shares other than TSA and its Affiliates or to effect an Equivalent Stock Subdivision or Equivalent Ratio Adjustment and TSA or TSA Exchangeco issues or distributes the same, or the economic equivalent of, such rights, options, securities, shares, evidences of indebtedness or other assets simultaneously to holders of the Exchangeable Shares or effects an Equivalent Stock Subdivision or Equivalent Ratio Adjustment; provided that, for greater certainty, the above restrictions shall not: (i) apply to any securities issued or distributed by TSA in order to give effect to and to consummate the transactions contemplated by, and in accordance with, the Plan of Arrangement or (ii) restrict TSA's overriding Redemption Call Right in the event of a TSA Spin-Out Decision Date. (b) TSA will not without the prior approval of TSA Exchangeco and the prior approval of the holders of the Exchangeable Shares given in accordance with Section 9.2 of the Exchangeable Share Provisions: (i) subdivide, redivide or change the then outstanding TSA Class A Common Shares into a greater number of TSA Class A Common Shares; or (ii) reduce, combine, consolidate or change the then outstanding TSA Class A Common Shares into a lesser number of TSA Class A Common Shares; or (iii) reclassify or otherwise change the TSA Class A Common Shares or effect an amalgamation, merger, reorganization or other transaction affecting the TSA Class A Common Shares; unless (x) TSA Exchangeco is permitted under applicable Law to make the same or an economically equivalent change to, or in the rights of holders of, the Exchangeable Shares and (y) the same or an economically equivalent change is made to, or in the rights of the holders of, the Exchangeable Shares. (c) Should the board of directors of TSA Exchangeco determine, in good faith and in its sole and absolute discretion, to provide economic equivalence for the purposes of any event referred to in section 2.7 (a) or (b) above, the board of directors of TSA Exchangeco shall determine, in its sole and absolute discretion, (with the assistance of such reputable and qualified independent financial advisors and/or other experts as the board of directors of TSA Exchangeco may require) such economic equivalence, and each such determination shall be conclusive and binding on TSA Exchangeco, all TSA Exchangeco security holders and TSA. In making such determination of economic equivalence, the following factors shall, without excluding other factors determined by the board of directors of TSA Exchangeco to be relevant, be considered by the board of directors of TSA Exchangeco : (i) in the case of any stock dividend or other distribution payable in TSA Class A Common Shares, the number of such shares issued in proportion to the number of TSA Class A Common Shares previously outstanding; (ii) in the case of the issuance or distribution of any rights, options or warrants to subscribe for or purchase TSA Class A Common Shares (or securities exchangeable for or convertible into or carrying rights to acquire TSA Class A Common Shares), the relationship between the exercise price of each such right, option or warrant and the Current Market Price; (iii) in the case of the issuance or distribution of any other form of property (including without limitation any securities of TSA of any class other than TSA Class A Common Shares, any rights, options or warrants other than those referred to in Subsection (b) above, any evidences of indebtedness of TSA or any assets of TSA), the relationship between the fair market value (as determined by the board of directors of TSA Exchangeco in the manner above contemplated) of such property to be issued or distributed with respect to each outstanding TSA Class A Common Share and the Current Market Price; (iv) in the case of any subdivision, re-division or change of the then outstanding TSA Class A Common Shares into a greater number of TSA Class A Common Shares or the reduction, combination or consolidation or change of the then outstanding TSA Class A Common Shares into a lesser number of TSA Class A Common Shares or any amalgamation, merger, re-organization or other transaction effecting the TSA Class A Common Shares, the effect thereof on the then outstanding shares of TSA Class A Common Shares; and (v) 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 TSA Class A Common Shares as a result of differences between Tax Laws of Canada, the United Kingdom, 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). (d) TSA Exchangeco agrees that, to the extent required, and subject to TSA's overriding Redemption Call Right in the event of a TSA Spin-Out Decision Date, upon due notice from TSA, TSA Exchangeco will use its best efforts to take or cause to be taken such steps as may be necessary for the purposes of ensuring that appropriate dividends are paid or other distributions are made by TSA Exchangeco, or changes are made to the Exchangeable Shares or that an Equivalent Ratio Adjustment is made, in order to implement the required economic equivalence with respect to TSA Class A Common Shares 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 TSA Class A Common Shares (an "Offer") is proposed by TSA or is proposed to TSA or its shareholders and is recommended by the board of directors of TSA, or is otherwise effected or to be effected with the consent or approval of the board of directors of TSA and the Exchangeable Shares are not redeemed by TSA Exchangeco or purchased by TSA Holdco (or TSA) pursuant to the Redemption Call Right or Automatic Exchange Rights, TSA will use its reasonable efforts in good faith to take all such actions and do all such things as are reasonably necessary or desirable to enable and permit holders of Exchangeable Shares other than TSA and its Affiliates to participate in such Offer to the same extent and on an economically equivalent basis as the holders of TSA Class A Common Shares, without discrimination. Without limiting the generality of the foregoing, TSA will use its reasonable efforts in good faith to ensure that holders of Exchangeable Shares may participate in each such Offer without being required to retract Exchangeable Shares as against TSA Exchangeco (or, if so required, to ensure that any such retraction shall be effective only upon, and shall be conditional upon, the closing of such Offer and only to the extent necessary to tender or deposit to the Offer). Nothing herein shall affect the rights of TSA Exchangeco to redeem (or TSA Holdco or TSA to purchase pursuant to the Redemption Call Right or Automatic Exchange Rights) Exchangeable Shares, as applicable, in the event of a TSA Control Transaction. 2.9 Ownership of Outstanding Shares of TSA Exchangeco TSA covenants and agrees in favour of TSA Exchangeco that, as long as any outstanding Exchangeable Shares are owned by any Person other than TSA or its Affiliates, TSA will be and remain the direct or indirect beneficial owner of all issued and outstanding voting shares in the capital of TSA Exchangeco and of all of the issued and outstanding shares of TSA Holdco, unless obtaining the prior approval of TSA Exchangeco and the prior approval of the holders of the Exchangeable Shares given in accordance with Section 9.2 of the Exchangeable Share Provisions, and provided that this shall not prohibit a reorganization of TSA Exchangeco or TSA Holdco which results in TSA or its Affiliates assuming or succeeding to the rights and obligations of TSA Exchangeco and TSA Holdco hereunder, but provided further that no such reorganization shall result in the holders of Exchangeable Shares becoming shareholders or otherwise beneficially interested in any body corporate or other entity which does not afford its shareholders (or other equity holders) limited liability. 2.10 TSA and Affiliates Not to Vote Exchangeable Shares TSA covenants and agrees that it will appoint and cause to be appointed proxy holders with respect to all Exchangeable Shares held by TSA and its Affiliates, specifically including TSA Holdco, 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. TSA further covenants and agrees that it will not, and will cause each of its Affiliates (including TSA Holdco) not to, exercise any voting rights that may be exercisable by holders of Exchangeable Shares from time to time pursuant to the Exchangeable Share Provisions or pursuant to the provisions of the ABCA (or any successor or other corporate statute by which TSA Exchangeco may in the future be governed) with respect to any Exchangeable Shares held by it or by TSA Holdco, TSA or by TSA's Affiliates in respect of any matter considered at any meeting of holders of Exchangeable Shares. 2.11 Due Performance On and after the Effective Date, TSA shall duly and timely perform all of its obligations provided for in the Plan of Arrangement, including any obligations that may arise upon the exercise of TSA's rights under the Exchangeable Share Provisions. ARTICLE III GENERAL 3.1 Term This Agreement shall come into force and be effective as of the date hereof and shall terminate and be of no further force and effect at such time as no Exchangeable Shares (or securities or rights convertible into or exchangeable for or carrying rights to acquire Exchangeable Shares) are held by any party other than TSA and any of its Affiliates. 3.2 Changes in Capital of TSA and TSA Exchangeco Notwithstanding the provisions of Section 3.4 hereof, at all times after the occurrence of any event effected pursuant to Section 2.7 or 2.8 hereof or otherwise, as a result of which either the TSA Class A Common Shares or the Exchangeable Shares or both are in any way changed, this Agreement shall forthwith be amended and modified as necessary in order that it shall apply with full force and effect, mutatis mutandis, to all new securities into which TSA Class A Common Shares or the Exchangeable Shares or both are so changed and the parties hereto shall execute and deliver an agreement in writing giving effect to and evidencing such necessary amendments and modifications. 3.3 Severability If any provision of this Agreement, or the application thereof, will for any reason and to any extent be invalid or unenforceable, the remainder of this Agreement and application of such provision to other persons or circumstances will be interpreted so as reasonably to effect the intent of the parties hereto.

Such dividends shall be cumulative from the Effective Date and shall be payable in arrears, when and as declared by the Board of Directors of the Corporation, on January 11 of each year (such date being referred to as the "Dividend Payment Date"), commencing on January 11, 2002. The period from January 11, 2001 through January 11, 2002 and each period between consecutive Dividend Payment Dates thereafter shall be referred to as a "Dividend Period". Each such dividend shall be paid to the holders of record of the Preferred Shares on the corresponding Record Date. The term "Record Date" means the twentieth (20th) day preceding the Dividend Payment Date, or such other date designated by the Board of Directors of the Corporation with respect to the relevant dividend. Dividends on account of arrears for any past Dividend Periods may be declared and paid at any time, without reference to any Dividend Payment Date, to holders of record on such date, not exceeding 50 days preceding the payment date thereof, as may be fixed by the Board of Directors. No dividends shall be payable in respect of any period less than a full Dividend Period except as specifically provided in these share provisions. (b) In the event that full cash dividends are not paid or made available to the holders of all outstanding Preferred Shares, and funds available shall be insufficient to permit payment in full in cash to all such holders of the amounts to which they are then entitled, the entire amount available for payment of such cash dividends shall be distributed among the holders of the Preferred Shares ratably in proportion to the full amount to which they would otherwise be respectively entitled, and any remainder not paid in cash to the holders of the Preferred Shares shall cumulate as provided in (c) below. (c) If, on any Dividend Payment Date, the Holders of the Preferred Shares shall not have received the full dividends provided for in the other provisions of this Section, then such dividends shall cumulate, whether or not earned or declared, with additional dividends thereon for each succeeding full Dividend Period during which such dividends shall remain unpaid. Unpaid dividends for any period less than a full Dividend Period shall cumulate on a day-today basis and shall be computed on the basis of a 365 day year. (d) No dividends shall be paid on the Preferred Shares for so long as the Corporation is in default of any obligation to declare or pay a dividend on the Exchangeable Shares. (e) For greater certainty, on a retraction or redemption of less than all of the outstanding Preferred Shares, the Corporation shall not be required to pay the Dividend Amount at such time on any Preferred Shares not designated for such retraction or redemption. 2.2. Cheques of the Corporation payable at any branch of the bankers of the Corporation shall be issued in respect of any cash dividends contemplated by Section 3.1 hereof and the sending of such a cheque to each holder of a Preferred Share shall satisfy the cash dividend represented thereby unless the cheque is not paid on presentation. All dividends shall be subject to any reduction or adjustment for Tax required to be deducted and withheld from such dividends paid or credited by the Corporation. No holder of a Preferred Share shall be entitled to recover by action or other legal process against the Corporation any dividend that is represented by a cheque that has not been duly presented to the Corporation's bankers for payment or that otherwise remains unclaimed for a period of six years from the date on which such dividend was payable. 2.3. Except as provided in Section 2.1, the holders of Preferred Shares shall not be entitled to receive dividends in respect thereof. 2.4. The Corporation will not pay a dividend or make any distribution in respect of any shares ranking junior to the Preferred Shares if the Corporation is then in default of any dividend obligations with respect to the Preferred Shares. ARTICLE 3 DISTRIBUTION ON LIQUIDATION 3.1. On any distribution of the assets of the Corporation among its shareholders for the purpose of winding up its affairs, a holder of Preferred Shares shall be entitled, subject to applicable Law, to receive from the assets of the Corporation in respect of each Preferred Share held by such holder on the effective date (the "Liquidation Date") of such liquidation, dissolution or winding-up, after any distribution of any part of the assets of the Corporation among the holders of the Exchangeable Shares and before any distribution on the Common Shares and any other shares ranking junior to the Preferred Shares, an amount per share equal to the Liquidation Amount. In connection with payment of the Liquidation Amount, the Corporation shall be entitled to deduct and withhold from any consideration otherwise payable to any such holder such amounts as the Corporation, is required or permitted to deduct and withhold with respect to such payment under the ITA or any other provision of applicable Tax Law, in each case, as amended or succeeded; provided that such withheld amount shall not be remitted prior to two (2) Business Days prior to that date such amount is required by Law to be remitted and where certificates issued pursuant to Subsection 116(2) or 116(4) of the ITA, if applicable, are delivered prior to such required remittance date, such withheld amount shall be released to the holder except to the extent that amounts were withheld or deducted pursuant to another provision of applicable Tax Law. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes hereof as having been paid to the holder of the Preferred Shares in respect of which such deduction and withholding was made, provided that such withheld amounts are actually remitted to the appropriate Taxing Authority and a receipt evidencing such remittance is delivered to such holder. 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 of the consideration otherwise payable to such holder, the Corporation, as agent of such holder, is hereby authorized to sell or otherwise dispose of such portion of the consideration as is necessary to provide sufficient funds to it to enable it to comply with such deduction or withholding requirement and the Corporation, shall notify such holder thereof and remit to such holder any unapplied balance of the net proceeds of such sale. If the proceeds of such sale are insufficient to fund the required withholding, such holder shall forthwith pay to the Corporation, or remit to the applicable Taxing Authority, the deficiency. Such holder shall bear all reasonable costs and expenses associated with any sale by the Corporation, pursuant to the two immediately preceding sentences. 3.2. On or promptly after the Liquidation Date and subject to the terms hereof, the Corporation shall cause to be delivered to the holders of the Preferred Shares the Liquidation Amount for each such Preferred Share upon presentation and surrender of the certificates representing such Preferred Shares, together with such other documents and instruments as may be required to effect a transfer of Preferred Shares under any applicable Law and the memorandum and articles of association of the Corporation and such additional documents and instruments as the Transfer Agent may reasonably require, at the registered office of the Corporation or at any office of the Transfer Agent as may be specified by the Corporation by notice to the holders of the Preferred Shares. Payment of the total Liquidation Amount for such Preferred 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 Preferred Shares or by holding for pick up by the holder at the registered office of the Corporation a cheque of the Corporation payable at par at any branch of the bankers of the Corporation in payment thereof (less any Tax required to be deducted and withheld from the total Liquidation Amount by the Corporation without interest). On and after the Liquidation Date, the holders of the Preferred Shares shall cease to be holders of such Preferred 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 Preferred 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 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 total Liquidation Amount in respect of the Preferred Shares represented by certificates that have not at the Liquidation Date been surrendered by the holders thereof in a custodial account with any chartered bank or trust company in Canada. Upon such deposit being made, the rights of the holders of Preferred Shares after such deposit shall be limited to receiving their proportionate part of the total Liquidation Amount (less any Tax required to be deducted and withheld therefrom) without interest for such Preferred Shares so deposited, against presentation and surrender of the said certificates held by them, respectively, in accordance with the foregoing provisions. Any certificate which represented a Preferred Share that has not been deposited, with all other instruments required by this Section 3.2, on or prior to the first anniversary of the Liquidation Date, shall cease to represent a claim or interest of any kind or nature as a holder of a Preferred Share. 3.3. After the Corporation has satisfied its obligations to pay the holders of the Preferred Shares the Liquidation Amount per Preferred Share pursuant to Section 3.1 of these share provisions, such holders shall not be entitled to share in any further distribution of the assets of the Corporation. ARTICLE 4 RETRACTION OF PREFERRED SHARES BY HOLDER 4.1. A holder of Preferred Shares shall be entitled: (i) upon the occurrence of a TSA Control Transaction; or (ii) at any time during the period commencing on the second anniversary of the Effective Date and ending on the day immediately prior to the fifth anniversary of the Effective Date, subject to the exercise of the Retraction Call Right and otherwise upon compliance with the provisions of this Article 4, to require the Corporation to redeem any or all of the Preferred Shares registered in the name of such holder for an amount per Preferred Share (the "Retraction Price") equal to the product of: (a) the Current Market Price on the Retraction Date; and (b) the Ratio. The Retraction Price shall be satisfied in full by the Corporation causing to be delivered to such holder that number of TSA Class A Common Shares equal to the Ratio, provided that fractional TSA Class A Common Shares shall not be issued and in lieu thereof the Corporation will deliver a cheque payable at par at any branch of the bankers of the Corporation in respect of the Fractional Share Amount, less any Tax required to be deducted or withheld therefrom. To effect such redemption, the holder shall present and surrender at the registered office of the Corporation the certificate or certificates representing the Preferred 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 Preferred Shares under applicable Law and the memorandum and articles of association of the Corporation and such additional documents and instruments as the Secretary of the Corporation 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 Preferred 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 ten (10) Business Days nor more than fifteen (15) 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 fifteenth (15th) Business Day after the date on which the Retraction Request is received by the Corporation; (c) acknowledging the overriding right (the "Retraction Call Right") of TSA Subco to purchase all but not fewer 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 to TSA Subco in accordance with the Retraction Call Right on the terms and conditions set out in Section 4.3 below; and (d) stating whether the holder is a Canadian Resident or is not a Canadian Resident. 4.2. Subject to the exercise by TSA Subco of the Retraction Call Right, upon receipt by the Corporation in the manner specified in Section 4.1 hereof of a certificate or certificates representing the number of Preferred 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 4.8, 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. If only a part of the Preferred Shares represented by any certificate are redeemed (or purchased by TSA Subco pursuant to the Retraction Call Right), a new certificate for the balance of such Preferred Shares shall be issued to the holder at the expense of the Corporation. 4.3. The Corporation acknowledges that it is bound by the Call and Right of First Refusal Agreement to immediately notify TSA Subco upon receipt by the Corporation of a Retraction Request and to provide a copy of such Retraction Request to TSA Subco. If TSA Subco has notified the Corporation in writing of its determination to exercise the Retraction Call Right (the "Call Notice") within five (5) Business Days of notification to TSA Subco by the Corporation of the receipt by the Corporation of the Retraction Request, and provided that the Retraction Request is not revoked by the holder in the manner specified in Section 4.8, the Retraction Request shall thereupon be considered only to be an offer by the holder to sell the Retracted Shares to TSA Subco in accordance with the Retraction Call Right. In such event, the Corporation shall not redeem the Retracted Shares. In the event that TSA Subco does not deliver a TSA Call Notice within such five (5) Business Day period or, notwithstanding anything else in this Section 4.3, if TSA Subco has so delivered a TSA Call Notice but fails to comply with its obligations to purchase the Retracted Shares, and provided that Retraction Request is not revoked by the holder in the manner specified in Section 4.8, the Corporation shall redeem the Retracted Shares on the Retraction Date and in the manner otherwise contemplated in this Article 5. Should TSA Subco assign the Retraction Call Right with respect to any Retraction Request to TSA or an Affiliate of TSA pursuant to the Call and Right of First Refusal Agreement, all references to TSA Subco in these share provisions with respect to the exercise of the Retraction Call Right in respect of which the assignment is made shall be deemed to refer to such assignee. 4.4. A holder who is not a Canadian Resident shall deliver with each Retraction Request a certificate satisfactory to the Corporation or TSA Subco, as the case may be, acting reasonably, issued pursuant to Subsection 116(2) of the ITA, with respect to the Preferred Shares being exchanged, having as the "certificate limit" as defined in Subsection 116(2) of the ITA, an amount no less than the cost of the Preferred Shares (which may be equal to the fair market value of the TSA Class A Common Shares and any cash receivable by the holder) to the Corporation or TSA Subco, as the case may be. In the case of a holder who is a partnership, the holder shall also provide a certificate confirming the name and address of each member thereof and the percentage of partnership interest held by each member. In the event that a holder fails to deliver one of the requisite certificates described with such holder's Retraction Request or, if the Corporation is required to deduct or withhold any amount under any other provision of applicable Tax Law, the Corporation shall be entitled to deduct and withhold from any consideration otherwise payable to any such holder such amounts as the Corporation is required or permitted to deduct and withhold with respect to such payment under the ITA or any other provision of applicable Tax Law, in each case, as amended or succeeded; provided that such withheld amount shall not be remitted prior to two (2) Business Days prior to the date such amount is required by Law to be remitted and where such certificate or a certificate issued pursuant to Subsection 116(4) satisfactory to the Corporation, acting reasonably, is delivered prior to such required remittance date, such withheld amount shall be released to the holder except to the extent that amounts were withheld or deducted pursuant to another provision of applicable Tax Law. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes hereof as having been paid to such holder of the Preferred Shares in respect of such deduction and withholding was made, provided that such withheld amounts are actually remitted to the appropriate Taxing Authority and a receipt evidencing such remittance is delivered to such holder. 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 of the consideration otherwise payable to such holder, the Corporation, as agent of such holder, is hereby authorized to sell or otherwise dispose of (or itself take title thereto at the then-Current Market Price) such portion of the consideration as is necessary to provide sufficient funds to it to enable it to comply with such deduction or withholding requirement and the Corporation shall notify such holder thereof and remit to such holder any unapplied balance of the net proceeds of such sale. If the proceeds of such sale are insufficient to fund the required withholding, such holder shall forthwith pay to the Corporation or remit to the applicable Taxing Authority the deficiency. Such holder shall bear all reasonable costs and expenses associated with any sale by the Corporation, pursuant to the two immediately preceding sentences. 4.5. The Corporation, shall deliver to the relevant holder, at the address of the holder recorded in the securities register of the Corporation for the Preferred 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, certificates representing fully paid and non-assessable TSA Class A Common Shares registered in the name of the holder or in such other name as the holder may request, and, if applicable, a cheque payable at par at any branch of the bankers of the Corporation in respect of any Fractional Share Amount, in each case, less any amounts withheld on account of Tax required to be deducted and withheld therefrom, and such delivery of such certificates and cheques on behalf of the Corporation, shall be deemed to be payment of and shall satisfy and discharge all liability for the total Retraction Price, to the extent that the same is represented by such share certificates and cheques (plus any Tax deducted and withheld therefrom and remitted to the proper Taxing Authority without interest), unless such cheque is not paid on due presentation. 4.6. 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 his proportionate part of the total Retraction Price, unless upon presentation and surrender of certificates in accordance with the foregoing provisions, the Retracted Shares are not purchased pursuant to the exercise of the Retraction Call Right or if payment of the total Retraction Price is not made as provided in Section 4.5, in which case the rights of such holder shall remain unaffected until the total Retraction Price 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 other requisite documents has been made in accordance with the foregoing provisions and either the Retraction Price has been satisfied or the Retracted Shares have been purchased pursuant to the exercise of the Retraction Call Right, the holder of the Retracted Shares so redeemed by the Corporation or purchased by TSA Subco or its permitted assignee shall thereafter be considered and deemed for all purposes to be a holder of the TSA Class A Common Shares delivered to it. 4.7. Notwithstanding any other provision of this Article 4, 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 solvency requirements or other provisions of applicable Law, including, without limitation, the NSCA and United States securities Laws. If the Corporation believes that on any Retraction Date it would not be permitted by any of such provisions to redeem all the Retracted Shares tendered for redemption on such date, and provided that TSA Subco shall not have exercised the Retraction Call Right with respect to all 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 at least two (2) Business Days 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 solvency requirements or other provisions of applicable Law, including, without limitation, the NSCA and United States securities Laws, the Corporation shall redeem the maximum number of whole Preferred Shares which the Board of Directors determine the Corporation is, on the Retraction Date, permitted to redeem, which shall be selected as nearly as may be pro rata (disregarding fractions) in proportion to the total number of Preferred Shares tendered for retraction by each holder thereof and the Corporation 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 4.2 hereof. 4.8. A holder of Retracted Shares may, by notice in writing given by such 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 shall be null and void and, for greater certainty, the revocable offer constituted by the Retraction Request to sell the Retracted Shares to TSA Subco shall be deemed to have been revoked. ARTICLE 5 EARLY REDEMPTION OF PREFERRED SHARES BY THE CORPORATION 5.1. Subject to applicable Law (including solvency restrictions which may require redemption of fewer than all of the Preferred Shares on a partial, pro-rata basis), and if TSA Subco or its permitted assignee does not exercise the Early Redemption Call Right, the Corporation shall on the Early Redemption Date redeem the whole of the then outstanding Preferred Shares (except where the redemption is to be made only with respect to the Preferred Shares of a holder who was an employee of TSA or of an Affiliate of TSA and whose employment has been terminated, in which event only the Preferred Shares of the Holder will be redeemed) on payment of an amount (the "Early Redemption Price") per Preferred Share equal to the greater of (i) the Liquidation Amount; and (ii) the fair market value of a Preferred Share on the Early Redemption Date. In the absence of agreement, by the Corporation and all holders whose Preferred Shares are subject to redemption, as to the fair market value of each Preferred Share, then such fair market value shall be deemed to be the sum of (a) the Present Value of dividends payable thereon with respect to periods commencing on the day immediately after the Early Redemption Date through the Mandatory Redemption Date and (b) the product of: (i) the Current Market Price on the Early Redemption Date; and (ii) the Ratio. The Early Redemption Price shall be satisfied in full by the Corporation causing to be delivered to each holder of Preferred Shares that number of TSA Class A Common Shares equal to the quotient of (i) the Early Redemption Price; divided by (ii) the Current Market Price on the Early Redemption Date, provided that fractional TSA A Class A Common Shares shall not be issued and in lieu thereof the Corporation will deliver a cheque payable at par at any branch of the bankers of the Corporation in respect of the Fractional Share Amount, less any Tax required to be deducted or withheld therefrom. 5.2. In any case of a redemption of Preferred Shares under this Article 5, the Corporation shall, at least ten (10) Business Days before the Early Redemption Date (other than a Early Redemption Date established in connection with a TSA Control Transaction), send or cause to be sent to each holder of Preferred Shares a notice in writing of the redemption by the Corporation, of the Preferred Shares held by such holder. In the case of an Early Redemption Date established in connection with a TSA Control Transaction, the written notice of redemption by the Corporation, on as many days prior written notice as may be determined by the Board of Directors of the Corporation, acting in good faith and in its sole discretion and with a view to permitting the holders of Preferred Shares sufficient time to exchange their Preferred Shares prior to the record date for determination of the registered holders of TSA Class A Common Shares in order to participate in a TSA Control Transaction, to be reasonably practicable in the circumstances. In any such case, such notice shall set out the Early Redemption Date. 5.3. On or before the Early Redemption Date, a holder of Preferred Shares shall deliver to the Corporation a certificate stating whether the holder is a Canadian Resident or is not a Canadian Resident. On or before the Early Redemption Date, a holder of Preferred Shares who is not a Canadian Resident shall deliver to the Corporation or TSA Subco, as the case may be, a certificate issued pursuant to Subsection 116(2) of the ITA, with respect to the Preferred Shares being redeemed having as the "certificate limit" as defined in Subsection 116(2) of the ITA, an amount no less than the cost of the Preferred Shares (which may be equal to the fair market value of the TSA Class A Common Shares and any cash receivable by such holder) to the Corporation or TSA Subco, as the case may be. In the case of a holder who is a partnership, the holder shall also provide a certificate confirming the name and address of each member thereof and the percentage of partnership interest held by each member. In the event that a holder fails to deliver one of the requisite certificates described or if the Corporation, or TSA Subco, as the case may be, is required to deduct or withhold any amount under any other provision of applicable Tax Law, the Corporation or TSA Subco, as the case may be, shall be entitled to deduct and withhold from any consideration otherwise payable to any such holder such amounts as the Corporation or TSA Subco, as the case may be, is required or permitted to deduct and withhold with respect to such payment under the ITA or any other provision of applicable Tax Law, in each case, as amended or succeeded; provided that such withheld amount shall not be remitted prior to two (2) Business Days prior to the date such amount is required by Law to be remitted and where such certificate or a certificate issued pursuant to Subsection 116(4) satisfactory to the Corporation or TSA Subco, as the case may be, acting reasonably, is delivered prior to such required remittance date, such withheld amount shall be released to the holder except to the extent that amounts were withheld or deducted pursuant to another provision of applicable Tax Law. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes hereof as having been paid to such holder of the Preferred Shares in respect of which such deduction and withholding was made, provided that such withheld amounts are actually remitted to the appropriate Taxing Authority and a receipt evidencing such remittance is delivered to such holder. 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 of the consideration otherwise payable to such holder, the Corporation or TSA Subco, as the case may be, as agent of such holder, is hereby authorized to sell or otherwise dispose of (or itself take title at the then-Current Market Price) such portion of the consideration as is necessary to provide sufficient funds to it to enable it to comply with such deduction or withholding requirement and the Corporation or TSA Subco, as the case may be, shall notify such holder thereof and remit to such holder any unapplied balance of the net proceeds of such sale. If the proceeds of such sale are insufficient to fund the required withholding, such holder shall forthwith pay to the Corporation or TSA Subco, as the case may be, or remit to the applicable Taxing Authority the deficiency. Such holder shall bear all reasonable costs and expenses associated with any sale by the Corporation or TSA Subco, as the case may be, pursuant to the two immediately preceding sentences. 5.4. On or after the Early Redemption Date and subject to the exercise by TSA Subco or its permitted assignee of the Early Redemption Call Right: (a) the Corporation shall cause to be delivered to the holders of the Preferred Shares to be redeemed the Early Redemption Price for each such Preferred Share, upon presentation and surrender at the registered office of the Corporation, together with such other documents and instruments as may be required to effect a transfer of Preferred Shares under applicable Law and the memorandum and articles of association of the Corporation and such additional documents and instruments as the Secretary of the Corporation may reasonably require. (b) Payment of the total Early Redemption Price for such Preferred Shares shall be made by delivery to each holder, at the address of the holder recorded in the securities register of the Corporation or by holding for pick up by the holder at the registered office of the Corporation of certificates representing fully paid and non-assessable TSA Class A Common Shares and, if applicable, a cheque of the Corporation payable at par at any branch of the bankers of the Corporation in respect of the Fractional Share Amount (less any Tax required to be deducted and withheld from the total Early Redemption Price by the Corporation without interest). (c) On and after the Early Redemption Date, the holders of the Preferred Shares called for redemption shall cease to be holders of such Preferred 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 Early Redemption Price, unless payment of the total Early Redemption Price for such Preferred 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 total Early Redemption Price has been paid in the manner hereinbefore provided. (d) The Corporation shall have the right at any time after the sending of notice of its intention to redeem the Preferred Shares as aforesaid to deposit or cause to be deposited the total Early Redemption Price for the Preferred Shares so called for redemption, or of such of the said Preferred 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 with any chartered bank or trust company in Canada named in such notice, less any amounts withheld on account of Tax required to be deducted and withheld therefrom. Upon the later of such deposit being made and the Early Redemption Date, the Preferred Shares in respect of which such deposit shall have been made shall be redeemed and the rights of the holders thereof after such deposit or Early Redemption Date, as the case may be, shall be limited to receiving their proportionate part of the total Early Redemption Price for such Preferred 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 the total Early Redemption Price, the holders of the Preferred Shares shall thereafter be considered and deemed for all purposes to be holders of the TSA Class A Common Shares delivered to them. Any certificate which represented a Preferred Share that has not been deposited, with all other instruments required by this Section 5.4, on or prior to the first anniversary of the Early Redemption Date, shall cease to represent a claim or interest of any kind or nature as a holder of a Preferred Share. 5.5. If TSA Subco or a permitted assignee of TSA Subco exercises the Early Redemption Call Right, the holders of Preferred Shares subject to the redemption shall be obligated to transfer their Preferred Shares to TSA Subco or its assignee, as the case may be, in accordance with the terms of the Early Redemption Call Right and the Corporation shall not redeem the Preferred Shares. ARTICLE 6 MANDATORY REDEMPTION OF PREFERRED SHARES BY THE CORPORATION 6.1. Subject to applicable Law (including solvency restrictions which may require redemption of fewer than all of the Preferred Shares on a partial, pro-rata basis), the Corporation shall, on the Mandatory Redemption Date, redeem the whole of the then outstanding Preferred Shares for an amount per share equal to the Liquidation Amount (the "Mandatory Redemption Price"). 6.2. In any case of a redemption of Preferred Shares under this Article 6, the Corporation shall, at least ten (10) Business Days before the Mandatory Redemption Date, send or cause to be sent to each holder of Preferred Shares a notice in writing of the redemption of the Corporation of the Preferred Shares held by such holder.

In the event that a holder fails to deliver one of the requisite certificates described or if the Corporation is required to deduct or withhold any amount under any other provision of applicable Tax Law, the Corporation shall be entitled to deduct and withhold from any consideration otherwise payable to any such holder such amounts as the Corporation is required or permitted to deduct and withhold with respect to such payment under the ITA or any other provision of applicable Tax Law, in each case, as amended or succeeded; provided that such withheld amount shall not be remitted prior to two (2) Business Days prior to the date such amount is required by Law to be remitted and where such certificate or a certificate issued pursuant to Subsection 116(4) satisfactory to the Corporation, acting reasonably, is delivered prior to such required remittance date, such withheld amount shall be released to the holder except to the extent that amounts were withheld or deducted pursuant to another provision of applicable Tax Law. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes hereof as having been paid to such holder of the Preferred Shares in respect of which such deduction and withholding was made, provided that such withheld amounts are actually remitted to the appropriate Taxing Authority and a receipt evidencing such remittance is delivered to such holder. 6.4. On or after the Mandatory Redemption Date, the Corporation shall cause to be delivered to the holders of the Preferred Shares to be redeemed the Mandatory Redemption Price for each such Preferred Share, upon presentation and surrender at the registered office of the Corporation of the certificates representing such Preferred Shares, together with such other documents and instruments as may be required to effect a transfer of Preferred Shares under applicable Law and the memorandum and articles of association of the Corporation and such additional documents and instruments as the Secretary of the Corporation may reasonably require. Payment of the total Mandatory Redemption Price for such Preferred Shares shall be made by delivery to each holder, at the address of the holder recorded in the securities register of the Corporation or by holding for pick up by the holder at the registered office of the Corporation, a cheque of the Corporation payable at par at any branch of the bankers of the Corporation in respect of the full amount of the Mandatory Redemption Price (less any Tax required to be deducted and withheld from the total Mandatory Redemption Price by the Corporation without interest). On and after the Mandatory Redemption Date, the holders of the Preferred Shares called for redemption shall cease to be holders of such Preferred 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 Mandatory Redemption Price, unless payment of the total Mandatory Redemption Price for such Preferred 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 total Mandatory 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 Preferred Shares as aforesaid to deposit or cause to be deposited the total Mandatory Redemption Price for the Preferred Shares so called for redemption, or of such of the said Preferred 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 with any chartered bank or trust company in Canada named in such notice, less any amounts withheld on account of Tax required to be deducted and withheld therefrom. Upon the later of such deposit being made and the Mandatory Redemption Date, the Preferred Shares in respect whereof such deposit shall have been made shall be redeemed and the rights of the holders thereof after such deposit or Mandatory Redemption Date, as the case may be, shall be limited to receiving their proportionate part of the total Mandatory Redemption Price for such Preferred Shares so deposited, against presentation and surrender of the said certificates held by them, respectively, in accordance with the foregoing provisions. Any certificate which represented a Preferred Share that has not been deposited, with all other instruments required by this Section 6.4, on or prior to the first anniversary of the Mandatory Redemption Date, shall cease to represent a claim or interest of any kind or nature as a holder of a Preferred Share. ARTICLE 7 VOTING RIGHTS 7.1.

Each holder of a Preferred Share, whether of record or beneficially, by virtue of becoming and being such a holder shall be deemed to acknowledge each of the Retraction Call Right and the Early Redemption Call Right, in each case, in favour of TSA Subco and its permitted assigns and the overriding nature thereof in connection with the retraction or early redemption of Preferred Shares, as the case may be, and to be bound thereby in favour of TSA Subco and its permitted assigns as provided in the Call and Right of First Refusal Agreement. ARTICLE 9 RESTRICTIONS ON TRANSFER 9.1. Any transfer of Preferred Shares shall require the approval of all of the holders of Preferred Shares, expressed by written resolution, which approval will be given (i) if the proposed transferee is TSA Subco or its assignee under the Call and Right of First Refusal Agreement or the Preferred Shares are redeemed by TSA Exchangeco; or (ii) provided the proposed transferee of the Preferred Shares (if other than TSA Subco or its permitted assignee under the Call and Right of First Refusal Agreement) has agreed in writing with the transferor, TSA Subco and the Corporation, to be bound by the provisions of the Call and Right of First Refusal Agreement.

Any notice, request or other communication to be given to the Corporation by a holder of Preferred Shares shall be in writing and shall be valid and effective if given by mail (postage prepaid) or by facsimile or by delivery to the registered office of the Corporation and addressed to the attention of the Secretary. Any such notice, request or other communication, if given by mail, facsimile or delivery, shall only be deemed to have been given and received upon actual receipt thereof by the Corporation. 10.2.

including the holders of shares of TSA Class A Common Shares (a "TSA Consent"),
each Holder shall be entitled to instruct the Trustee to cast and exercise, in
the manner instructed, one of the votes comprised in the Voting Rights for each
Exchangeable Share owned of record by such Holder on the record date established

                           representative  of the  management of TSA to exercise
                           such Holder Votes;

(d)               a statement  that if no such  instructions  are received  from
                  the  Holder,   the  Holder  Votes  to  which  such  Holder  is

                  not be  earlier  than the  close  of  business  on the  second
                  Business  Day  prior to such  meeting  or not  later  than the
                  time period  allowed in the notice  calling the TSA Consent to
                  allow for a direct  response  by the  Holder in regards to the

                  revoking or amending such instructions.

                  The materials referred to above are to be provided by TSA to
the Trustee. For the purpose of determining Holder Votes to which a Holder is
entitled in respect of any such TSA Meeting or TSA Consent, the number of
Exchangeable Shares owned of record by the Holder shall be determined at the
close of business on the record date established by TSA or by applicable Law for
purposes of determining shareholders entitled to vote at such TSA Meeting or to
give written consent in connection with such TSA Consent. TSA will notify the
Trustee in writing of any decision of the board of directors of TSA with respect
to the calling of any such TSA Meeting or the seeking of any such TSA Consent
and shall provide all necessary information and materials to the Trustee in each
case promptly and in any event in sufficient time to enable the Trustee to
perform its obligations contemplated by this Section 4.3.

4.4               Copies of Shareholder Information

                  TSA will deliver to the Trustee copies of all proxy materials,

Common Shares), information statements, reports (including without limitation
all interim and annual financial statements) and other written communications
that, in each case, are to be distributed from time to time to holders of TSA
Class A Common Shares in sufficient quantities and in sufficient time so as to
enable the Trustee to send those materials to each Holder at the same time as
such materials are first sent to holders of TSA Class A Common Shares. The
Trustee will mail or otherwise send to each Holder, at the expense of TSA,
copies of all such materials (and all materials specifically directed to the
Holders or to the Trustee for the benefit of the Holders by TSA) received by the
Trustee from TSA at the same time as such materials are first sent to holders of
TSA Class A Common Shares. The Trustee will also make copies of all such
materials available for inspection by any Holder at the Trustee's principal
office in the city of Minneapolis, Minnesota.

4.5               Other Materials

                  Immediately after receipt by TSA or any shareholder of TSA of
any material sent or given generally to the holders of TSA Class A Common Shares
by or on behalf of a third party, including without limitation dissident proxy
and information circulars (and related information and material) and tender and
exchange offer circulars (and related information and material), TSA shall use
its reasonable efforts to obtain and deliver to the Trustee copies thereof in
sufficient quantities so as to enable the Trustee to forward such material
(unless the same has been provided directly to Holders by such third party) to
each Holder as soon as possible thereafter. As soon as practicable after receipt
thereof, the Trustee will mail or otherwise send to each Holder, at the expense
of TSA, copies of all such materials received by the Trustee from TSA. The
Trustee will also make copies of all such materials available for inspection by
any Holder at the Trustee's principal office in the city of Minneapolis,
Minnesota.

                  TSA Exchangeco shall, (a) prior to each annual, general and

with a TSA Meeting or a TSA Consent, at the close of business on the record date
established by TSA or pursuant to applicable law for determining the holders of
TSA Class A Common Shares entitled to receive notice of and/or to vote at such

List shall be delivered to the Trustee promptly after receipt by TSA Exchangeco
of such request or after the record date for such meeting or seeking of consent,
as the case may be, is set and in any event within sufficient time as to enable
the Trustee to perform its obligations under this Agreement. TSA agrees to give
TSA Exchangeco written notice (with a copy to the Trustee) of the calling of any

therefor, sufficiently prior to the date of the calling of such meeting or
seeking of such consent so as to enable TSA Exchangeco to perform its

                  provided,   however,   that  such  written   instructions  are
                  received  by the  Trustee  from the  Holder  prior to the time
                  and date fixed by it for receipt of such  instructions  in the

                  representatives  shall  sign and  deliver  to such  Holder (or
                  its  designee)  a proxy  to  exercise  personally  the  Holder
                  Votes  as  to  which  such   Holder  is   otherwise   entitled
                  hereunder to direct the vote, if such Holder  either:  (i) has

                  Holder (or its  designee)  exercising  such Holder Votes shall
                  have the same  rights as the  Trustee to speak at the  meeting
                  in respect of any  matter,  question or  proposition,  to vote
                  by way of ballot at the  meeting  in  respect  of any  matter,

exercisable in respect of the Exchangeable Shares held by such Holder, including
the right to instruct the Trustee as to the voting of or to vote personally such
Holder Votes, shall be deemed to be surrendered by the Holder to TSA or TSA
Holdco, as the case may be, and such Holder Votes and the Voting Rights
represented thereby shall cease immediately upon the delivery by such Holder to
the Trustee of the certificates representing such Exchangeable Shares in
connection with the exercise by the Holder of the Exchange Right or the

                  be vested  with full legal  ownership  of the  Exchange  Right
                  and the  Automatic  Exchange  Rights and shall be  entitled to
                  exercise  all  of the  rights  and  powers  of an  owner  with
                  respect  to the  Exchange  Right  and the  Automatic  Exchange
                  Rights, provided that the Trustee shall:

(i)                        hold the Exchange Right and the Automatic Exchange
                           Rights and the legal title thereto as trustee solely
                           for the use and benefit of the Holders in accordance
                           with the provisions of this Agreement; and

                           any such rights for any purpose other than the
                           purposes for which this Trust is created pursuant to
                           this Agreement.

                  obligations in respect of the Exchange Right and Automatic
                  Exchange Right to TSA Holdco, with the result that all
                  references to TSA in this Agreement with respect to such
                  rights and obligations in respect of which the delegation or
                  assignment is made shall be deemed to refer to TSA Holdco.

by the Trustee. The Trustee shall exercise the Exchange Right only on the basis
of instructions received pursuant to this Article 5 from Holders entitled to

Trustee shall not exercise or permit the exercise of the Exchange Right.

Holdco or TSA under the Exchange Right shall be an amount per share equal to:

(a)               the Current Market Price of a TSA Class A Common Shares on the
                  last Business Day prior to the day of closing of the purchase
                  and sale of such Exchangeable Share under the Exchange Right;
                  plus

(b)      the Dividend Amount; plus

(c)      the Fractional Share Amount.

In connection with each exercise of the Exchange Right, TSA Holdco or TSA will
provide to the Trustee an Officer's Certificate setting forth the calculation of
the purchase price for each Exchangeable Share. The purchase price for each such
Exchangeable Share so purchased shall be satisfied in full by TSA Holdco or TSA,
as applicable, issuing and delivering or causing to be delivered to the Trustee,
on behalf of the relevant Holder, one TSA Class A Common Shares plus a cheque
for the balance of the purchase price, if any, due under sub-paragraphs (b) and
(c) above, plus to the extent not paid by TSA Exchangeco, all dividends declared
on TSA Class A Common Shares that have not been declared on such Exchangeable
Shares or in respect of which economic equivalence therefor has not been
provided in accordance with Section 3.1 of the Exchangeable Share Provisions
(provided that if the record date for any such declared and unpaid dividends
occurs on or after the day of closing of such purchase and sale, the purchase
price shall not include such additional amounts equivalent to such declared and
unpaid dividends) without interest (but less any amounts withheld pursuant to
Section 5.13).

5.5               Exercise Instructions

         Subject to the terms and conditions herein set forth, a Holder shall be
entitled, upon the occurrence and during the continuance of a TSA Exchangeco
Insolvency Event, to instruct the Trustee to exercise the Exchange Right with
respect to all or any part of the Exchangeable Shares registered in the name of
such Holder on the books of TSA Exchangeco. To cause the exercise of the
Exchange Right by the Trustee, the Holder shall deliver to the Trustee, in
person or by mail, at its principal transfer office in Minneapolis, Minnesota,
or at such other places 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 TSA Holdco or TSA 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
under the Memorandum and Articles of Association of TSA Exchangeco 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)      the tax residency of the holder;

(ii)                       that the Holder thereby instructs the Trustee to
                           exercise the Exchange Right so as to require TSA or
                           TSA Holdco to purchase from the Holder the number of
                           Exchangeable Shares specified therein;

(iii)                      that such Holder has good title to and owns all such
                           Exchangeable Shares to be acquired by TSA Holdco or
                           TSA free and clear of all liens, claims and
                           encumbrances;

(iv)                       the names in which the certificates representing TSA
                           Class A Common Shares issuable in connection with the
                           exercise of the Exchange Right are to be issued; and

(v)      the names and  addresses  of the persons to whom such new  certificates
                            should be delivered; and

(b)               payment (or evidence satisfactory to the Trustee, TSA, TSA
                  Holdco and TSA Exchangeco 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 TSA Holdco or TSA
under the Exchange Right, a new certificate for the balance of such Exchangeable
Shares shall be issued by TSA Exchangeco to the Holder at the expense of TSA
Exchangeco.

5.6               Delivery of TSA Class A Common Shares; Effect of Exercise

Promptly after receipt of the certificates representing the Exchangeable Shares
which the Holder desires TSA Holdco or TSA 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 (and payment of Taxes, if any,
payable as contemplated in Section 5.8 hereof or evidence thereof)), duly
endorsed in blank, the Trustee shall notify TSA Holdco, TSA Exchangeco and TSA
of its receipt of the same, which notice to TSA Holdco, TSA Exchangeco and TSA
shall constitute exercise of the Exchange Right by the Trustee on behalf of the
holder of such Exchangeable Shares, and TSA Holdco or TSA, as applicable, 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 certificates for the number of TSA
Class A Common Shares issuable in connection with the exercise of the Exchange
Right, which shares shall be validly issued, fully paid, non-assessable, and
will be free and clear of Encumbrances attributable to, or arising due to, any
action or omission of TSA, and cheques for the balance, if any, of the total
purchase price therefor without interest, but less any amounts withheld pursuant
to Section 5.13 hereof; 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, TSA Exchangeco, TSA and TSA Holdco 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 TSA Nova
Holdco, TSA and TSA Exchangeco of the exercise of the Exchange Right, as
provided in this Section 5.6, the closing of the transaction of purchase and
sale contemplated by the Exchange Right shall be deemed to have occurred, and
the Holder of such Exchangeable Shares shall be deemed to have transferred to
TSA Holdco or TSA, as applicable, all of its right, title and interest in and to
such Exchangeable Shares and in the related interest in the Trust Estate and
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 the requisite number of TSA Class A Common Shares (together with a cheque
for the balance, if any, of the total purchase price therefor without interest)
is not allotted and delivered by TSA Holdco or TSA to the Trustee, for delivery
to such Holder (or to such other persons, if any, properly designated by such
Holder), within five Business Days of the date of the giving of such notice by
the Trustee, in which case the rights of the Holder shall remain unaffected
until such TSA Class A Common Shares are so allotted and delivered by TSA Holdco
or TSA and any such cheque is so delivered and paid. Upon delivery by TSA Holdco
or TSA to the Trustee of such TSA Class A Common Shares, the Trustee shall
deliver such TSA Class A Common Shares to such Holder (or to such other persons,
if any, properly designated by such Holder). 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 TSA Class A Common Shares
delivered to it pursuant to the Exchange Right.

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 TSA Exchangeco to
redeem any or all of the Exchangeable Shares held by the Holder (the "Retracted
Shares") and is notified by TSA Exchangeco pursuant to Section 6.7 of the
Exchangeable Share Provisions that TSA Exchangeco will not be permitted as a
result of solvency requirements of applicable Law to redeem all such Retracted
Shares, provided that TSA Holdco or TSA 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 TSA Exchangeco
pursuant to Section 6.1 of the Exchangeable Share Provisions, the Retraction
Request will constitute and 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 TSA Exchangeco is unable to redeem. In
any such event, TSA Exchangeco hereby agrees with the Trustee and in favor of
the Holder immediately to notify the Trustee of such prohibition against TSA
Exchangeco 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 TSA Exchangeco 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 that TSA
Exchangeco is not permitted to redeem and will require TSA Holdco or TSA 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 TSA Holdco or TSA
pursuant to the Exchange Right or the Automatic Exchange Rights, the share
certificate or certificates representing TSA Class A Common Shares 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 neither TSA Holdco, TSA, TSA Exchangeco nor 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,
                  TSA, TSA Holdco and TSA Exchangeco that such Taxes, if any,
                  have been paid.

5.9               Notice of TSA Exchangeco Insolvency Event

                  Immediately upon the occurrence of a TSA Exchangeco Insolvency
Event or any event which with the giving of notice or the passage of time or
both would be an TSA Exchangeco Insolvency Event, TSA Exchangeco and TSA shall
give written notice thereof to the Trustee. As soon as practicable after
receiving notice from TSA Exchangeco and TSA or from any other person of the
occurrence of an TSA Exchangeco Insolvency Event, the Trustee will mail to each
Holder, at the expense of TSA, a notice of such TSA Exchangeco Insolvency Event
in the form provided by TSA, which notice shall contain a brief statement of the
right of the Holders with respect to the Exchange Right.

5.10              Issuance and Listing of TSA Class A Common Shares

                  For so long as any Exchangeable Shares remain outstanding to
other than TSA and its Affiliates, TSA will cause the TSA Class A Common Shares
which are to be issued directly in consideration for MDL Class A Shares or to be
issued from time to time upon exchange of the Exchangeable Shares, to be quoted
on the NASDAQ or such other exchange or quotation system to the same extent as
TSA stock is quoted generally, subject only to official notice of issuance.

5.11              Reservation of TSA Class A Common Shares

                  TSA hereby represents, warrants and covenants for the benefit
of the holders of the Exchangeable Shares 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 TSA
Class A Common Shares:

(a)               as is equal to the sum of:

                  (i)      the  number  of   Exchangeable   Shares   issued  and
                           outstanding to Holders from time to time; and

                  (ii)     the number of Exchangeable Shares issuable upon the
                           exercise of all rights of Holders thereof to acquire
                           Exchangeable Shares outstanding from time to time;
                           and

(b)               as are  now  and may  hereafter  be  required  to  enable  and
                  permit  TSA  Exchangeco  and TSA  Holdco and TSA to meet their
                  respective   obligations   hereunder,    under   the   Support
                  Agreement,  under the Exchangeable  Share Provisions and under
                  any other  security or  commitment  pursuant to which TSA, TSA
                  Holdco or TSA  Exchangeco  may now or hereafter be required to
                  issue or deliver TSA Class A Common Shares to Holders.

                  (i)      in the  event of any  determination  by the  board of

                           effective  date  of  such  liquidation,  dissolution,
                           winding-up or other distribution; and

                           affairs, in each case where TSA has failed to contest
                           in good faith any such proceeding within 30 days of
                           becoming aware thereof.

(b)               As soon as practicable  following  receipt by the Trustee from
                  TSA of  notice  of  any  event  (a  "TSA  Liquidation  Event")
                  contemplated  by Subsection  5.12(a)(i) or 5.12(a)(ii)  above,
                  the Trustee  will give  notice  thereof to the  Holders.  Such
                  notice  shall  include a brief  description  of the  automatic

                  pro rata basis with the  holders of TSA Class A Common  Shares
                  in the  distribution  of  assets of TSA in  connection  with a
                  TSA  Liquidation  Event,  on the fifth  Business  Day prior to
                  the  effective  date (the  "TSA  Liquidation  Event  Effective
                  Date")   of   a   TSA    Liquidation    Event   all   of   the
                  then-outstanding  Exchangeable  Shares  held by Persons  other
                  than TSA and its Affiliates shall be  automatically  exchanged
                  for TSA Class A Common Shares (the "Automatic  Exchange").  To
                  effect  such  Automatic  Exchange,   TSA  Holdco  or  TSA,  as
                  applicable,  shall  purchase each  Exchangeable  Share held by
                  Persons other than TSA and its  Affiliates  outstanding on the

                  Common  Shares  on the  fifth  Business  Day  prior to the TSA
                  Liquidation  Event  Effective  Date,  which,   subject  to  an
                  Equivalent  Ratio  Adjustment,  shall be  satisfied in full by
                  TSA issuing to the Holder one TSA Class A Common  Share,  plus
                  (b) the Dividend  Amount;  and plus (c) the  Fractional  Share
                  Amount;   and  plus  (d)  to  the   extent  not  paid  by  TSA
                  Exchangeco,  all  dividends  declared  on TSA  Class A  Common
                  Shares  that  have  not  been  declared  on such  Exchangeable
                  Shares or in respect of which  economic  equivalence  therefor
                  has not been  provided in  accordance  with Section 3.1 of the
                  Exchangeable  Share  Provisions  (provided  that if the record
                  date for any such declared and unpaid  dividends  occurs on or
                  after  the day of  closing  of such  purchase  and  sale,  the
                  purchase  price  shall not  include  such  additional  amounts
                  equivalent  to  such  declared  and  unpaid   dividends).   In
                  connection  with such  Automatic  Exchange,  TSA Holdco or TSA
                  will provide to the Trustee an Officer's  Certificate  setting
                  forth  the   calculation   of  the  purchase  price  for  each
                  Exchangeable Share.

(d)               On the fifth Business Day prior to the TSA  Liquidation  Event
                  Effective  Date,  the closing of the  transaction  of purchase
                  and  sale  contemplated  by the  Automatic  Exchange  shall be
                  deemed  to have  occurred,  and each  Holder  of  Exchangeable
                  Shares  shall be deemed to have  transferred  to TSA Holdco or
                  TSA 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 TSA  Holdco or TSA shall  deliver to
                  the Holder the TSA Class A Common  Shares  issuable  upon such
                  Automatic  Exchange and on the  applicable  payment date shall
                  deliver to the  Trustee  for  delivery  to the Holder a cheque
                  for the  balance,  if any,  of the  total  purchase  price for
                  such  Exchangeable  Shares  without  interest,  but  less  any
                  amounts   withheld    pursuant   to   Section   5.13   hereof.
                  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 TSA Class A
                  Common   Shares   issued  to  it  pursuant  to  the  Automatic
                  Exchange  of  Exchangeable  Shares  for  TSA  Class  A  Common
                  Shares  and the  certificates  held by the  Holder  previously
                  representing the  Exchangeable  Shares exchanged by the Holder
                  with TSA Holdco or TSA  pursuant  to such  Automatic  Exchange
                  shall  thereafter  be  deemed  to  represent  the TSA  Class A
                  Common  Shares  delivered  to the  Holder by TSA Holdco or TSA
                  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  TSA  Class  A
                  Common  Shares,  duly  endorsed  in blank and  accompanied  by
                  such  instruments  of  transfer  as TSA  and  TSA  Holdco  may
                  reasonably  require,  TSA Holdco or TSA shall deliver or cause
                  to be delivered to the Holder  certificates  representing  the
                  TSA Class A Common Shares of which the Holder is the holder.

5.13              Withholding Rights

                  Prior to the exchange or disposition of any Exchangeable
Shares in accordance with this Article, each Holder shall deliver to TSA Holdco
or TSA, at or before such time:

(a)               a  certificate  confirming  that such  Holder is a resident of
                  Canada for the purposes of the ITA; or

(b)               in the case of a Holder  who is a  non-resident  of Canada for
                  the  purposes of the ITA, a  certificate  satisfactory  to TSA
                  Holdco  or  TSA  acting   reasonably,   issued   pursuant   to
                  subsection   116(2)   of  the  ITA,   with   respect   to  the
                  Exchangeable  Shares,  and having as the "certificate  limit",
                  as  defined  in  subsection  116(2)  of the ITA,  an amount no
                  less than the cost to TSA  Holdco or TSA,  as the case may be,
                  of the  Exchangeable  Shares  (which  may be equal to the fair
                  market value of the TSA Class A Common  Shares  receivable  by
                  such Holder).

                  In the case of a Holder who is a partnership, the Holder shall
also provide a certificate confirming the name and address of each member
thereof and the percentage of partnership interest held by each member (which
partners and percentages are clearly contemplated in the applicable
certificate).

                  In the event that a Holder fails to deliver the requisite
certificates described above at or before the exchange or disposition of such
shares, or in the event that TSA Holdco or TSA is required to deduct or withhold
any amount under any other provision of applicable Tax law, TSA Holdco or TSA
shall be entitled to deduct and withhold from any consideration otherwise
payable to any Holder such amounts as TSA Holdco or TSA is required or permitted
to deduct and withhold with respect to such payment under the ITA or any
provision of provincial or governmental tax law, in each case, as amended or
succeeded, provided that such withheld amount shall not be remitted prior to two
business days prior to the date such amount is required by law to be remitted
(the "Remittance Date") and where such certificate, or a certificate issued
pursuant to subsection 116(4) of the ITA satisfactory to TSA Holdco and TSA
acting reasonably, is delivered prior to such Remittance Date, such withheld
amount shall be released, to such Holder except to the extent that amounts were
withheld or deducted pursuant to another provision of applicable Tax law. To the
extent that amounts are so withheld, such withheld amounts shall be treated for
all purposes hereof 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. 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 of the consideration otherwise payable to the
Holder, TSA Holdco or TSA, as agent of such Holder, is hereby authorized to sell
or otherwise dispose of such portion of the consideration as is necessary to
provide sufficient funds to TSA Holdco or TSA to enable it to comply with such
deduction or withholding requirement and TSA Holdco or TSA shall notify the
Holder thereof and remit to such Holder any unapplied balance of the net
proceeds of such sale. If the proceeds of such sale are insufficient to fund the
required withholding, the Holder shall forthwith pay to TSA Holdco or TSA or
remit to the applicable taxing authority the deficiency. The Holder shall bear
all reasonable costs and expense associated with such sale by purchaser pursuant
to the two immediately preceding sentences.

                  During the term of this Agreement, TSA will not, without the
consent of the Holders, given in accordance with Section 9.2 of the Exchangeable
Share Provisions, issue any TSA Special Voting Shares in addition to the Special
Voting Share.


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, without limitation: (a) receipt and deposit of the Special Voting Share from TSA 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 TSA 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 TSA Class A Common Shares and cheques, 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 monies 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 hereunder of each other party hereto; 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. 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. 7.2 No Conflict of Interest The Trustee represents to each other party hereto 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 30 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 applicable court for an order that the Trustee be replaced as trustee hereunder. 7.3 Dealings With Transfer Agents, Registrars, Etc. TSA Exchangeco, TSA Holdco and TSA 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 the TSA Class A Common Shares; 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 the TSA Class A Common Shares, and any subsequent transfer agent of such shares, the share certificates issuable upon the exercise from time to time of the Exchange Right and pursuant to the Automatic Exchange Rights in the manner specified in Article 5 hereof. TSA Exchangeco and TSA shall irrevocably authorize their respective registrars and transfer agents to comply with all such requests. TSA covenants that it will supply its transfer agent with duly 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 TSA, TSA Holdco and TSA Exchangeco, at the Trustee's principal office in Minneapolis, Minnesota, correct and complete books and records of account relating to the Trustee's actions under this Agreement, including without limitation, all relevant data 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 December 1, 2001 and on or before December 1 in every year thereafter, so long as the Special Voting Share is on deposit with the Trustee, the Trustee shall transmit to TSA and TSA Exchangeco a brief report, dated as of the preceding September 30 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 delivery by TSA, or TSA Holdco of TSA Class A Common Shares 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 in the Trustee's sole judgement it had not previously reported and which, in the Trustee's sole judgement and opinion, materially affects the Trust Estate. 7.5 Income Tax Return and Reports The Trustee shall, to the extent necessary, prepare and file on behalf of the Trust appropriate 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, TSA 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 furnishing to the Trustee reasonable funding, security and indemnity against the costs, expenses (including reasonable counsel fees) 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 Special Voting Share pursuant to Article 4 hereof, and with respect to the Exchange Right pursuant to Article 5 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 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 statutory declarations, certificates, opinions or reports 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 if such statutory declarations, certificates, opinions or reports 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 TSA Exchangeco, TSA Holdco, and/or TSA 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 TSA Exchangeco, TSA Holdco, and/or TSA 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 TSA Exchangeco, TSA Holdco, and/or TSA 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 TSA Exchangeco, TSA Holdco, and/or TSA written notice requiring it to furnish such evidence in relation to any particular action or obligation specified in such notice. Such evidence shall consist of an Officer's Certificate of TSA Exchangeco, TSA Holdco, and/or TSA 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 or, the taking of any other action to be taken by the Trustee at the request or on the application of TSA Exchangeco, TSA Holdco, and/or TSA, 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 TSA Exchangeco, TSA Holdco, and/or TSA it shall be in the form of an Officer's Certificate or a statutory declaration. Each statutory declaration, Officer's 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: (a) declaring that he has read and understands the provisions of this trust agreement relating to the condition in question: (b) describing the nature and scope of the examination or investigation upon which he based the statutory declaration, certificate, statement or opinion; and (c) declaring that he has made such examination or investigation as he believes is necessary to enable him 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 TSA Exchangeco, TSA Holdco and/or TSA or otherwise, and may employ such assistants as may be necessary to the proper 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 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 discharge of its duties hereunder and in the management of the Trust. 7.11 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. 7.12 Authority to Carry on Business The Trustee represents to TSA Exchangeco, TSA Holdco, and TSA that at the date of execution and delivery by it of this Agreement it is authorized to carry on the business of a National Association in the United States, with authority to carry out its obligations hereunder but if, notwithstanding the provisions of this Section 7.12, it ceases to be so authorized to carry on such 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 but the Trustee shall, within 90 days after ceasing to be authorized to carry on such business in the United States, either become so authorized or resign in the manner and with the effect specified in Article 10 hereof. 7.13 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 8.1 Fees and Expenses of the Trustee TSA shall pay to the Trustee its annual fees and other charges 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 other than with respect to a dispute between one or more Holders and TSA and/or its Affiliates, in which event the Trustees fees will be paid by the non-prevailing party; provided that TSA and its Affiliates and the Holders 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 gross negligence, recklessness or willful misconduct. ARTICLE 9 INDEMNIFICATION AND LIMITATION OF LIABILITY 9.1 Indemnification of the Trustee TSA and TSA Exchangeco shall 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 Losses which, without fraud, negligence, recklessness, 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 its compliance with, any written or oral instructions delivered to the Trustee by TSA or its Affiliates pursuant hereto. In no case shall TSA and its Affiliates be liable under this indemnity for any claim against any of the Indemnified Parties unless TSA and TSA Exchangeco 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, TSA and TSA Exchangeco shall be entitled to participate at their own expense in the defense and, if TSA and TSA Exchangeco so elect at any time after receipt of such notice, they 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 TSA and TSA Exchangeco, such authorization not to be unreasonably withheld; or (ii) the named parties to any such suit include both the Trustee and TSA or TSA Exchangeco or other TSA Affiliates and the Trustee shall have been advised by counsel acceptable to TSA and TSA Exchangeco that there may be one or more legal defenses available to the Trustee that are different from or in addition to those available to TSA or its Affiliates and that an actual or potential conflict of interest exists (in which case TSA and TSA Exchangeco 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). 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 TSA, TSA Holdco and TSA Exchangeco specifying the date on which it desires to resign, provided that such notice shall never be given less than 60 days before such desired resignation date unless TSA, TSA Holdco and TSA Exchangeco otherwise agree and provided further that such resignation shall not take effect until the date of the appointment of a successor trustee and the acceptance of such appointment by the successor trustee. Upon receiving such notice of resignation, TSA, TSA Holdco and TSA Exchangeco shall promptly appoint a successor trustee by written instrument in duplicate, one copy of which shall be delivered to the resigning trustee and one copy to the successor trustee. Failing acceptance by a successor trustee, a successor trustee may be appointed by an order of the applicable courts of the Province of Alberta upon application of one or more of the parties hereto. 10.2 Removal The Trustee, or any trustee hereafter appointed, may be removed with or without cause, at any time on 30 days' prior notice by written instrument executed by TSA, TSA Holdco and TSA Exchangeco, in duplicate, one copy of which shall be delivered to the trustee so removed and one copy to the successor trustee. 10.3 Successor Trustee Any successor trustee appointed as provided under this Agreement shall execute, acknowledge and deliver to TSA, TSA Holdco and TSA Exchangeco and to its predecessor trustee an instrument accepting such appointment. Thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor under this Agreement, with like effect as if originally named as trustee in this Agreement. However, on the written request of TSA, TSA Holdco and TSA Exchangeco 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, TSA, TSA Holdco, TSA Exchangeco 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, TSA and TSA Exchangeco shall cause to be mailed notice of the succession of such trustee hereunder to each Holder specified in a List. If TSA or TSA Exchangeco 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 TSA Exchangeco. ARTICLE 11 TSA SUCCESSORS 11.1 Certain Requirements in Respect of Combination, Etc. Subject to and without limiting TSA's rights to redeem the Exchangeable Shares TSA, directly or indirectly, shall not consummate any transaction (whether by way of reconstruction, reorganization, consolidation, merger, transfer, sale, lease or otherwise) whereby all or substantially all of its undertaking, property and assets would become the property of any other person or, in the case of a merger, of the continuing corporation resulting therefrom unless, but may do so if: (i) such other person or continuing corporation (herein called the "TSA Successor"), by operation of Law, becomes, without more, bound by the terms and provisions of this Agreement or, if not so bound, executes, prior to or contemporaneously with the consummation of such transaction an agreement supplemental hereto and such other instruments (if any) as are reasonably satisfactory to the Trustee and are reasonably necessary or advisable to evidence the assumption by the TSA Successor of TSA's liability for all monies payable and property deliverable by TSA hereunder and the covenant of such TSA Successor to pay and deliver or cause to be delivered the same and its agreement to observe and perform all the covenants and obligations of TSA under this Agreement; and (ii) such transaction shall, to the satisfaction of the Trustee, acting reasonably, and in the opinion of legal counsel to the Trustee, be upon such terms and conditions as substantially preserve and does not impair in any material respect any of the rights, duties, powers and authorities of the Trustee or of the Holders hereunder. Nothing herein shall affect the rights of TSA Exchangeco to redeem (or TSA Holdco or TSA to purchase pursuant to the Redemption Call Right) Exchangeable Shares, as applicable. 11.2 Vesting of Powers in Successor Whenever the conditions of Section 11. 1 hereof have been duly observed and performed, the TSA Successor and the parties hereto, if required by Section 11.1 hereof, shall execute and deliver the supplemental agreement provided for in Section 12.5 hereof and thereupon TSA Successor shall possess and from time to time may exercise each and every right and power of TSA under this Agreement in the name of TSA or otherwise and any act or proceeding by any provision of this Agreement required to be done or performed by the board of directors of TSA or any officers of TSA may be done and performed with like force and effect by the directors or officers of such TSA Successor. 11.3 Wholly-Owned Subsidiaries Nothing herein shall be construed as preventing the amalgamation, merger or other combination of any wholly-owned direct or indirect subsidiary of TSA with or into TSA or with or into another wholly-owned direct or indirect subsidiary of TSA or the winding-up, liquidation or dissolution of any direct or indirect wholly-owned subsidiary of TSA provided that all of the assets of such subsidiary are transferred to TSA or another direct or indirect wholly-owned subsidiary of TSA, and any such transactions are expressly permitted by this Section 11.3. ARTICLE 12 AMENDMENTS AND SUPPLEMENTAL TRUST AGREEMENTS 12.1 Amendments, Modifications, Etc.

Holders may also approve any proposed amendment or modification by written consent of Holders holding not less than the minimum number of Exchangeable Shares that would be necessary to authorize or take such action at a meeting of Holders called for such purpose. Any such meeting or meetings shall be called and held, or written consent given shall be given in accordance with the by-laws of TSA Exchangeco, the Exchangeable Share Provisions and all applicable Laws. 12.4 Changes in Capital of TSA and TSA Exchangeco At all times after the occurrence of any event effected pursuant to Section 2.7 or Section 2.8 of the Support Agreement or otherwise, as a result of which either TSA Class A Common Shares or the Exchangeable Shares or both are in any way changed, this Agreement shall forthwith be amended and modified as necessary in order that it shall apply with full force and effect, mutatis mutandis, to all new securities into which the TSA Class A Common Shares or the Exchangeable Shares or both are so changed and the parties hereto shall execute and deliver a supplemental agreement giving effect to and evidencing such necessary amendments and modifications. 12.5 Execution of Supplemental Agreements No amendment to or modification or waiver of any of the provisions of this Agreement otherwise permitted hereunder shall be effective unless made in writing and signed by all of the parties hereto.

TSA will prepare and file the Registration Statement (as defined in the Combination Agreement) with the SEC. 2.7 Economic Equivalence So long as any Exchangeable Shares not owned by TSA or its Affiliates are outstanding: (a) TSA will not without the prior approval of TSA Exchangeco and the prior approval of the holders of the Exchangeable Shares given in accordance with Section 9.2 of the Exchangeable Share Provisions: (i) issue or distribute TSA Class A Common Shares (or securities exchangeable for or convertible into or carrying rights to acquire TSA Class A Common Shares) to the holders of all or substantially all of the then outstanding TSA Class A Common Shares by way of stock dividend (including a stock split payable as a stock dividend) or other distribution, other than an issue of TSA Class A Common Shares (or securities exchangeable for or convertible into or carrying rights to acquire TSA Class A Common Shares) to holders of TSA Class A Common Shares who exercise an option to receive dividends in TSA Class A Common Shares (or securities exchangeable for or convertible into or carrying rights to acquire TSA Class A Common Shares) in lieu of receiving cash dividends; (ii) issue or distribute rights, options or warrants to the holders of all or substantially all of the then outstanding TSA Class A Common Shares entitling them to subscribe for or to purchase TSA Class A Common Shares (or securities exchangeable for or convertible into or carrying rights to acquire TSA Class A Common Shares); or (iii) issue or distribute to the holders of all or substantially all of the then outstanding TSA Class A Common Shares: (A) shares or securities of TSA of any class other than TSA Class A Common Shares (other than shares convertible into or exchangeable for or carrying rights to acquire TSA Class A Common Shares); (B) rights, options or warrants other than those referred to in Section 2.7(a)(ii) above; (C) evidences of indebtedness of TSA; or (D) assets of TSA; unless TSA or TSA Exchangeco is permitted under applicable Law to issue or distribute the same, or the economic equivalent on a per share basis of, such rights, options, securities, shares, evidences of indebtedness or other assets to holders of the Exchangeable Shares other than TSA and its Affiliates or to effect an Equivalent Stock Subdivision or Equivalent Ratio Adjustment and TSA or TSA Exchangeco issues or distributes the same, or the economic equivalent of, such rights, options, securities, shares, evidences of indebtedness or other assets simultaneously to holders of the Exchangeable Shares or effects an Equivalent Stock Subdivision or Equivalent Ratio Adjustment; provided that, for greater certainty, the above restrictions shall not: (i) apply to any securities issued or distributed by TSA in order to give effect to and to consummate the transactions contemplated by, and in accordance with, the Plan of Arrangement or (ii) restrict TSA's overriding Redemption Call Right in the event of a TSA Spin-Out Decision Date. (b) TSA will not without the prior approval of TSA Exchangeco and the prior approval of the holders of the Exchangeable Shares given in accordance with Section 9.2 of the Exchangeable Share Provisions: (i) subdivide, redivide or change the then outstanding TSA Class A Common Shares into a greater number of TSA Class A Common Shares; or (ii) reduce, combine, consolidate or change the then outstanding TSA Class A Common Shares into a lesser number of TSA Class A Common Shares; or (iii) reclassify or otherwise change the TSA Class A Common Shares or effect an amalgamation, merger, reorganization or other transaction affecting the TSA Class A Common Shares; unless (x) TSA Exchangeco is permitted under applicable Law to make the same or an economically equivalent change to, or in the rights of holders of, the Exchangeable Shares and (y) the same or an economically equivalent change is made to, or in the rights of the holders of, the Exchangeable Shares. (c) Should the board of directors of TSA Exchangeco determine, in good faith and in its sole and absolute discretion, to provide economic equivalence for the purposes of any event referred to in section 2.7 (a) or (b) above, the board of directors of TSA Exchangeco shall determine, in its sole and absolute discretion, (with the assistance of such reputable and qualified independent financial advisors and/or other experts as the board of directors of TSA Exchangeco may require) such economic equivalence, and each such determination shall be conclusive and binding on TSA Exchangeco, all TSA Exchangeco security holders and TSA. In making such determination of economic equivalence, the following factors shall, without excluding other factors determined by the board of directors of TSA Exchangeco to be relevant, be considered by the board of directors of TSA Exchangeco : (i) in the case of any stock dividend or other distribution payable in TSA Class A Common Shares, the number of such shares issued in proportion to the number of TSA Class A Common Shares previously outstanding; (ii) in the case of the issuance or distribution of any rights, options or warrants to subscribe for or purchase TSA Class A Common Shares (or securities exchangeable for or convertible into or carrying rights to acquire TSA Class A Common Shares), the relationship between the exercise price of each such right, option or warrant and the Current Market Price; (iii) in the case of the issuance or distribution of any other form of property (including without limitation any securities of TSA of any class other than TSA Class A Common Shares, any rights, options or warrants other than those referred to in Subsection (b) above, any evidences of indebtedness of TSA or any assets of TSA), the relationship between the fair market value (as determined by the board of directors of TSA Exchangeco in the manner above contemplated) of such property to be issued or distributed with respect to each outstanding TSA Class A Common Share and the Current Market Price; (iv) in the case of any subdivision, re-division or change of the then outstanding TSA Class A Common Shares into a greater number of TSA Class A Common Shares or the reduction, combination or consolidation or change of the then outstanding TSA Class A Common Shares into a lesser number of TSA Class A Common Shares or any amalgamation, merger, re-organization or other transaction effecting the TSA Class A Common Shares, the effect thereof on the then outstanding shares of TSA Class A Common Shares; and (v) 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 TSA Class A Common Shares as a result of differences between Tax Laws of Canada, the United Kingdom, 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). (d) TSA Exchangeco agrees that, to the extent required, and subject to TSA's overriding Redemption Call Right in the event of a TSA Spin-Out Decision Date, upon due notice from TSA, TSA Exchangeco will use its best efforts to take or cause to be taken such steps as may be necessary for the purposes of ensuring that appropriate dividends are paid or other distributions are made by TSA Exchangeco, or changes are made to the Exchangeable Shares or that an Equivalent Ratio Adjustment is made, in order to implement the required economic equivalence with respect to TSA Class A Common Shares 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 TSA Class A Common Shares (an "Offer") is proposed by TSA or is proposed to TSA or its shareholders and is recommended by the board of directors of TSA, or is otherwise effected or to be effected with the consent or approval of the board of directors of TSA and the Exchangeable Shares are not redeemed by TSA Exchangeco or purchased by TSA Holdco (or TSA) pursuant to the Redemption Call Right or Automatic Exchange Rights, TSA will use its reasonable efforts in good faith to take all such actions and do all such things as are reasonably necessary or desirable to enable and permit holders of Exchangeable Shares other than TSA and its Affiliates to participate in such Offer to the same extent and on an economically equivalent basis as the holders of TSA Class A Common Shares, without discrimination. Without limiting the generality of the foregoing, TSA will use its reasonable efforts in good faith to ensure that holders of Exchangeable Shares may participate in each such Offer without being required to retract Exchangeable Shares as against TSA Exchangeco (or, if so required, to ensure that any such retraction shall be effective only upon, and shall be conditional upon, the closing of such Offer and only to the extent necessary to tender or deposit to the Offer). Nothing herein shall affect the rights of TSA Exchangeco to redeem (or TSA Holdco or TSA to purchase pursuant to the Redemption Call Right or Automatic Exchange Rights) Exchangeable Shares, as applicable, in the event of a TSA Control Transaction. 2.9 Ownership of Outstanding Shares of TSA Exchangeco TSA covenants and agrees in favour of TSA Exchangeco that, as long as any outstanding Exchangeable Shares are owned by any Person other than TSA or its Affiliates, TSA will be and remain the direct or indirect beneficial owner of all issued and outstanding voting shares in the capital of TSA Exchangeco and of all of the issued and outstanding shares of TSA Holdco, unless obtaining the prior approval of TSA Exchangeco and the prior approval of the holders of the Exchangeable Shares given in accordance with Section 9.2 of the Exchangeable Share Provisions, and provided that this shall not prohibit a reorganization of TSA Exchangeco or TSA Holdco which results in TSA or its Affiliates assuming or succeeding to the rights and obligations of TSA Exchangeco and TSA Holdco hereunder, but provided further that no such reorganization shall result in the holders of Exchangeable Shares becoming shareholders or otherwise beneficially interested in any body corporate or other entity which does not afford its shareholders (or other equity holders) limited liability. 2.10 TSA and Affiliates Not to Vote Exchangeable Shares TSA covenants and agrees that it will appoint and cause to be appointed proxy holders with respect to all Exchangeable Shares held by TSA and its Affiliates, specifically including TSA Holdco, 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. TSA further covenants and agrees that it will not, and will cause each of its Affiliates (including TSA Holdco) not to, exercise any voting rights that may be exercisable by holders of Exchangeable Shares from time to time pursuant to the Exchangeable Share Provisions or pursuant to the provisions of the ABCA (or any successor or other corporate statute by which TSA Exchangeco may in the future be governed) with respect to any Exchangeable Shares held by it or by TSA Holdco, TSA or by TSA's Affiliates in respect of any matter considered at any meeting of holders of Exchangeable Shares. 2.11 Due Performance On and after the Effective Date, TSA shall duly and timely perform all of its obligations provided for in the Plan of Arrangement, including any obligations that may arise upon the exercise of TSA's rights under the Exchangeable Share Provisions.
