(a) Parent shall issue and deliver to Parent FinanceCo, and shall cause Parent FinanceCo to deliver to Parent SubCo, that number of duly authorized, fully paid and non-assessable shares of Parent Common Stock that is equal to the lesser of

(i) the product of

A. 0.2229, and

(1) the number of Company Common Shares held by any Dissenting Shareholder who is ultimately entitled to be paid the fair value of the Company Common Shares held by such Dissenting Shareholder, and

(2) the number of Company Common Shares held by Parent, Company, any Subsidiary of Parent or any Subsidiary of Company,

and

(ii) the Maximum Share Number

the exact number of which is to be confirmed by way of a certificate of a director or officer of Parent, and filed with the corporate records of Parent, at such time that the number of shares of Parent Common Stock issuable under the Arrangement is finally determinable, and Parent SubCo shall issue, and be deemed to have issued, to Parent FinanceCo, in exchange therefor, 1,000 common shares in the capital of Parent SubCo.

- 7 -

(b) Subject to the proration adjustments set forth in Section 2.2(e), the outstanding Company Common Shares held by each Company Common Shareholder other than,

(i) Company Common Shares held by a Dissenting Shareholder who is ultimately entitled to be paid the fair value of the Company Common Shares held by such Dissenting Shareholder, or

(ii) Company Common Shares held by Parent, Company, any Subsidiary of Parent or any Subsidiary of Company (which shall not be exchanged under the Arrangement and shall be cancelled at the Effective Time and cease to exist),

will be transferred by the holder thereof to, and acquired by, Parent SubCo without any act or formality on the part of the holders of such Company Common Shares or Parent SubCo, free and clear of all Liens in exchange, with respect to each Company Common Share held by such holder, for, at such holder’s election (or deemed election): (x) the Purchase Price per Company Common Share in cash without interest (a “Cash Election”); or (y) a fraction of a fully paid and non-assessable share of Parent Common Stock as is equal to the Exchange Ratio (a “Stock Election”) payable, in each case, in accordance with Article 4, and the name of each such holder of Company Common Shares will be removed from the register of holders of Company Common Shares and added to the register of holders of Parent Common Stock, as applicable.

(c) After application of the proration provisions in Section 2.2(e) to all Company Common Shares in respect of which an election has been made by the holder thereof in accordance with Section 2.2(b), each Company Common Share in respect of which no effective election has been made by the holder thereof (other than Company Common Shares held by (i) a Dissenting Shareholder who is ultimately entitled to be paid the fair value of the Company Common Shares held by such Dissenting Shareholder and (ii) Parent, Company, any Subsidiary of Parent or any Subsidiary of Company) (“Non-Election Shares”) will be transferred to, and acquired by, Parent SubCo, without any act or formality on the part of the holder of such Company Common Share or Parent SubCo, free and clear of all Liens, and the holder shall be deemed to have elected to receive in exchange therefor (x) if the Aggregate Amount of Cash Elected equals or exceeds the Cash Available, such number of fully paid and non-assessable shares of Parent Common Stock as is equal to the Exchange Ratio, (y) if the Aggregate Number of Shares Elected equals or exceeds the Shares Available, the Purchase Price per Company Common Share in cash, without interest, or (z) if neither clause (x) or (y) is applicable, (1) an amount of cash, without interest, equal to (A) the Cash Available minus the Aggregate Amount of Cash Elected divided by (B) the number of outstanding Non-Election Shares (the “Non-Election Cash Amount”) and (2) the number of shares of Parent Common Stock as is equal to (A) the Exchange Ratio multiplied by (B) a fraction, calculated to four decimal places, the numerator of which is the Purchase Price per Company Common Share minus the

- 8 -

Non-Election Cash Amount and the denominator of which is the Purchase Price per Company Common Share, in all such cases payable in accordance with Article 4, and the name of each such holder of Company Common Shares will be removed from the register of holders of Company Common Shares and added to the register of holders of the Parent Common Stock, as applicable.

(d) Notwithstanding any provisions of this Plan of Arrangement, in no event shall the total number of shares of Parent Common Stock issued with respect to Company Common Shares that are outstanding immediately prior to the Effective Time exceed the Shares Available.

(e) The consideration which each holder of Company Common Shares has elected in accordance with Section 2.2(b) to receive in exchange for such holder’s Company Common Shares shall be subject to adjustment and proration on the following bases:

(i) if the Aggregate Amount of Cash Elected exceeds the Cash Available, then the amount of cash payable under the Arrangement to each holder of Company Common Shares who has made a Cash Election shall be prorated (based on the fraction equal to the Cash Available divided by the Aggregate Amount of Cash Elected) among all such holders so that the aggregate amount of cash payable to all such holders shall be equal to the Cash Available, each such holder shall be entitled to receive cash equal to the amount of cash payable to such holder after giving effect to the proration provisions of this Section 2.2(e)(i) and such holder shall be deemed to have elected to receive the number of shares of Parent Common Stock per Company Common Share equal to the Exchange Ratio in respect of the balance of such holder’s Company Common Shares in respect of which cash was elected but not available; and

(ii) if the Aggregate Number of Shares Elected exceeds the Shares Available, then the number of shares of Parent Common Stock issuable under the Arrangement to each holder of Company Common Shares who has made a Stock Election shall be prorated (based on the fraction equal to the Shares Available divided by the Aggregate Number of Shares Elected) among all such holders so that the number of shares of Parent Common Stock issuable to all such holders shall be equal to the Shares Available and each such holder shall be entitled to receive that number of shares of Parent Common Stock that is equal to the number of shares of Parent Common Stock issuable to such holder, after giving effect to the proration provisions of this Section 2.2(e)(ii), and an amount of cash, without interest, equal to (A) the difference between the number of shares of Parent Common Stock such holder elected to receive pursuant to Section 2.2(b) and the number of shares of Parent Common Stock such holder will be entitled to receive after giving effect to the proration provisions of this Section 2.2(e)(ii), (B) divided by the Exchange Ratio, and (C) multiplied by the Purchase Price per Company Common Share.

- 9 -

(f) Each Company Option outstanding immediately prior to the Effective Time shall be exchanged for or converted under the Company Share Option Plan into an option (a “Replacement Option”) to purchase that number of shares of Parent Common Stock equal to the number of Company Common Shares underlying such Company Option multiplied by the Exchange Ratio. For a Company Option

(i) with an exercise price denominated in Canadian dollars, such Replacement Option shall provide for an exercise price per share of Parent Common Stock in United States dollars equal to (x) the exercise price per Company Common Share of such Company Option immediately prior to the Effective Time divided by the Exchange Ratio, divided by (y) the Currency Exchange Rate, or

(ii) with an exercise price denominated in United States dollars, such Replacement Option shall provide for an exercise price per share of Parent Common Stock in United States dollars equal to the exercise price per Company Common Share of such Company Option immediately prior to the Effective Time divided by the Exchange Ratio;

provided that in no circumstance shall the exercise price per share of Parent Common Stock be less than $.01 and if the calculation results in an exercise price less than $.01, the exercise price shall be deemed to be $.01 per share of Parent Common Stock.

If the foregoing calculation results in a Replacement Option (A) being exercisable for a fraction of a share of Parent Common Stock, then the number of shares of Parent Common Stock subject to such Replacement Option shall be rounded down to the next whole number of shares of Parent Common Stock or (B) having an exercise price per share of Parent Common Stock that is a fraction of a cent, then the exercise price per share of Parent Common Stock under such Replacement Option shall be rounded up to the next whole cent.

Notwithstanding the above provisions of this Section 2.2(f)

(i) with respect to any Company Option, if the directors of Parent determine in good faith that the excess of the aggregate fair market value of the shares of Parent Common Stock subject to the Replacement Option immediately after the issuance of the Replacement Option over the aggregate option exercise price for such shares pursuant to the Replacement Option (such excess, referred to as the “Post-Exchange Option Value”) would otherwise exceed the excess of the aggregate fair market value of the Company Common Shares subject to the Company Option immediately before the issuance of the Replacement Option over the aggregate option exercise price for such shares pursuant to the Company Option (such excess, referred to as the “Pre-Exchange Option Value”), the previous provisions in this Section 2.2(f) shall be modified, but only to the extent necessary and in a manner that does not otherwise adversely affect the holder of the Replacement Option, so that the Post-Exchange Option Value does not exceed the Pre-Exchange Option Value; and

- 10 -

(ii) with respect only to a Company Option that is held by a resident of the United States, on a share by share comparison, the ratio of the option exercise price to the fair market value of the shares of Parent Common Stock subject to the Replacement Option immediately after the issuance of the Replacement Option will not be more favourable to the option holder than the ratio of the option exercise price to the fair market value of the Company Common Shares subject to the Company Option immediately before the issuance of the Replacement Option.

The term to expiry, conditions to and manner of exercising, vesting schedule and all other terms and conditions of each Replacement Option will otherwise be the same as the terms and conditions of the corresponding Company Option. Except as specified in this Plan of Arrangement, any document or agreement previously evidencing such Company Option shall thereafter evidence and be deemed to evidence such Replacement Option, with any adjustments deemed to be made thereto as are necessary to ensure consistency with the provisions of this Section 2.2(f).

(g) Each Company SAR outstanding immediately prior to the Effective Time shall be exchanged for or converted, under the Company Share Option Plan, into that number of replacement share appreciation rights (“Replacement SARs”) equal to such number of Company SARs multiplied by the Exchange Ratio. If the foregoing calculation, after aggregating all Company SARs attached to any particular Company Option, results in a number of Replacement SARs equal to a fraction, then the number of Replacement SARs granted in exchange for Company SARs pursuant to this Section 2.2(g) shall be rounded down to the next whole number. Any such Replacement SARs shall be attached to Replacement Options in the same way as Company SARs were attached to Company Options immediately prior to the Effective Time.

Each Replacement SAR shall entitle the holder thereof, at his or her discretion and pursuant to the terms of the Company Share Option Plan, to surrender to Parent the unexercised vested Replacement Options to which the Replacement SARs are attached and to receive from Parent such number of newly issued shares of Parent Common Stock as determined by the following formula:

Number of shares of Parent Common Stock to be newly issued upon exercise of Replacement SARs = Number of
Replacement SARs
exercised X Share Premium / Surrender Price

The directors of Parent shall make any adjustments to the terms of the Replacement SARs that are required to be consistent with any adjustments required to be made to the Replacement Options under Section 2.2(f) and in accordance with the principles of Section 2.2(f).

- 11 -

The term to expiry, conditions to and manner of exercising and all other terms and conditions of such Replacement SARs will otherwise be the same as the terms and conditions of such Company SARs. Except as specified in this Plan of Arrangement, any document or agreement previously evidencing such Company SARs shall thereafter evidence and be deemed to evidence the corresponding Replacement SARs, with any adjustments deemed to be made thereto as are necessary to ensure consistency with the provisions of Sections 2.2(g) and 2.2(f).

(h) Each Company RSU outstanding under the Company Stock Plans as of the Effective Time shall be deemed to become, under the relevant Company RSU Plan, a right (a “Parent RSU”) to acquire or receive (as the case may be) (i) that number of shares of Parent Common Stock equal to the number of Company Common Shares underlying such Company RSU multiplied by the Exchange Ratio, or (ii) in respect of the Company Global RSU Plan only, an amount of cash determined under the Company Global RSU Plan by reference to the value of a share of Parent Common Stock on NSYE, multiplied by the Exchange Ratio, rather than the value of a Company Common Share on NASDAQ, on the relevant date. If the foregoing calculation results in a Parent RSU being exercisable for a fraction of a share of Parent Common Stock, then the number of shares of Parent Common Stock subject to such Parent RSU shall be rounded down to the next whole number of shares of Parent Common Stock. Notwithstanding the above provisions of this Section 2.2(h), (i) in the case of a holder or participant under the relevant Company Stock Plan who is a resident of Canada for purposes of the ITA, if the directors of Parent determine in good faith that the excess of the aggregate fair market value of the shares of Parent Common Stock to be acquired or received under the Parent RSU immediately after the issuance of the Parent RSU (the “Post-Exchange RSU Value”) would otherwise exceed the aggregate fair market value of the Company Common Shares immediately before the issuance of the Parent RSU that would have been acquired or received under the Company RSU under the relevant Company Stock Plan (the “Pre-Exchange RSU Value”), the provisions provided in this Section 2.2(h) shall be modified, but only to the extent necessary and in a manner that does not otherwise adversely affect the holder of the Parent RSU, so that the Post-Exchange RSU Value does not exceed the Pre-Exchange RSU Value. Each Parent RSU shall otherwise be subject to the same terms and conditions applicable to the corresponding Company RSU under the relevant Company RSU Plan. Except as specified in this Plan of Arrangement, any document or agreement previously evidencing such Company RSUs shall thereafter evidence and be deemed to reference Parent RSUs, with any adjustments deemed to be made thereto as are necessary to ensure consistency with the provisions of this Section 2.2(h);

(i) Notwithstanding the terms of the Company Deferred Share Unit Plan, each Company DSU outstanding immediately prior to the Effective Time, whether vested or unvested shall be cancelled and terminated by the Company and each holder thereof, whether vested or unvested, shall be entitled to receive from the

- 12 -

Company, in consideration therefor, the Purchase Price per Company Common Share in cash per Company DSU, provided, however that in the case of an Eligible Director who is a resident of the United States, the amount payable pursuant to this Section 2.2(i) shall be payable on the later of January 1, 2007 and the Effective Time; and

(j) The Company Deferred Share Unit Plan shall be cancelled.

2.3 Elections

(a) The initial election date (the “Initial Election Date”) shall be [September 29], 2006, unless otherwise agreed in writing by Parent and Company. If, after the Letter of Transmittal and Election Form has been mailed, Company and Parent determine that the Effective Date is not reasonably likely to occur by the tenth Business Day after the Initial Election Date, then the date by which Letters of Transmittal and Election Forms must be received shall be extended to a date which the parties expect to be not more than 10 Business Days before the Effective Date. In the event that the date by which Letters of Transmittal and Election Forms must be received is extended, Company shall provide at least 5 days’ notice of the new Election Date (and shall provide such notice prior to the Initial Election Date if practicable) to holders of Company Common Shares by means of press release broadly disseminated in Canada and the United States. Any duly completed Letter of Transmittal and Election Form deposited by the Election Deadline on the Initial Election Date shall not be required to be re-deposited if the date by which Letters of Transmittal and Election Forms must be received is extended pursuant hereto. The Initial Election Date, as extended and published pursuant to the terms hereof, shall be the “Election Date”.

(b) The Letter of Transmittal and Election Form shall be sent not less than 21 days prior to the Initial Election Date to each holder of record of Company Common Shares.

(c) Each Person who, at or prior to the Election Deadline, is a holder of record of Company Common Shares will be entitled, with respect to each of their shares, to make an election at or prior to the Election Deadline to receive (i) cash or (ii) Parent Common Stock, in exchange for each such Company Common Share on the basis set forth herein and in the Letter of Transmittal and Election Form.

(d) Company and Parent shall have the right to make rules, not inconsistent with this Plan of Arrangement, governing the validity and effectiveness of the Letter of Transmittal and Election Forms or other related documents, and the manner and extent to which elections of cash and Parent Common Stock are to be taken into account in making the determinations required by this Plan of Arrangement.

2.4 Adjustments to the Purchase Price per Company Common Share

In the event that Company changes the number of Company Common Shares or securities convertible or exchangeable into or exercisable for Company Common Shares, or Parent changes the number of shares of Parent Common Stock or securities convertible or exchangeable into or exercisable for shares of Parent Common Stock, issued and outstanding prior to the Effective Time as a result of a reclassification, stock split (including reverse split), dividend or distribution, recapitalization, merger, subdivision, combination, issuer tender or exchange offer or other similar transaction, the Purchase Price per Company Common Share will be adjusted appropriately as determined by Parent and Company to provide the holders of Company Common Shares the same economic effect as contemplated by the Acquisition Agreement and the Plan of Arrangement prior to such reclassification, split, dividend, distribution, recapitalization, merger, subdivision, combination, tender or exchange offer or similar transaction.
