Subject to the terms and conditions hereof, at the Time of Closing Holdco covenants and agrees to sell, assign and transfer to the Purchaser and the Purchaser covenants and agrees to purchase from Holdco 73,115,756 issued and outstanding Common Shares (the “Purchased Shares”).

2.2 Purchase Price.

The purchase price payable by the Purchaser to Holdco for the Purchased Shares (the “Purchase Price”) shall be Cdn.$28.00 per Purchased Share. The Purchase Price shall be payable at the Time of Closing as follows:

	(a)		the Purchaser shall issue to Holdco a secured promissory note in the form set out in Schedule A (“Note A”), guaranteed by the Guarantor, in the principal amount of U.S.$1,327,345,890; and

	(b)		the Purchaser shall issue to Holdco a secured promissory note in the form set out in Schedule B (“Note B”), guaranteed by the Guarantor, in the principal amount of U.S.$375,000,000,

which shall constitute full discharge of the Purchase Price for the Purchased Shares.

2.3 Direction of Proceeds, Subscription and Issue of Debenture.

(a) Holdco agrees and directs that the proceeds from the repayment of the principal amount (but for greater certainty not the interest) of Note B shall be paid to XCC in full satisfaction of the subscription price payable by Holdco to XCC for the Debenture.

(b) Pursuant to the Subscription Agreement Holdco agrees to subscribe for and purchase the Debenture (as defined below), and the Guarantor agrees to procure that XCC shall issue a guaranteed convertible debenture of XCC in the aggregate paid-up amount of U.S.$375,000,000 (the “Debenture”) on the Debenture Issue Date at the Issue Price (being a price of 100% of the principal amount of the Debenture) and on the terms set out in the term sheet for the Debenture attached hereto as Schedule C and the Subscription Agreement, subject to such modifications as the Guarantor and the Vendors may, acting reasonably, agree; and

-6-

provided that Holdco may direct, prior to the Debenture Issue Date, that the Debenture be issued in the name of a direct or indirect wholly-owned subsidiary of Brascan. The Guarantor agrees to execute and deliver, and to cause the Purchaser to execute and deliver, the Subscription Agreement to Holdco, and Holdco agrees to execute and deliver the Subscription Agreement to the Guarantor and the Purchaser, on August 15, 2005.

(c) If the Guarantor is unable to procure the issuance by XCC of the Debenture on or by September 15, 2005, then the Guarantor agrees to procure that a direct or indirect wholly-owned subsidiary of the Guarantor other than XCC (the “Substitute Issuer”) will issue to Holdco, on or before the maturity date of Note B (as defined therein), a guaranteed convertible debenture (the “Substitute Debenture”) in the same principal amount and on the same terms and conditions in all material respects (other than the identity and jurisdiction of organization of the Substitute Issuer) as provided in Schedule C and having tax consequences for Holdco that are not demonstrably less advantageous to Holdco than the Debenture, subject to such modifications as the Guarantor and the Vendors may, acting reasonably, agree; and provided that Holdco may direct, prior to the date the Substitute Debenture is issued, that the Substitute Debenture be issued in the name of another direct or indirect wholly-owned subsidiary of Brascan.

(d) Holdco agrees that in circumstances where section 2.3(c) applies it will enter into a subscription agreement (the “Substitute Subscription Agreement”) with the Substitute Issuer and the Guarantor on terms and conditions substantially the same as the Subscription Agreement (and which shall include provisions substantially similar in respect of the Substitute Issuer and the Substitute Debenture as sections 4.5, 4.8 and 4.10) and will subscribe for and purchase the Substitute Debenture pursuant to the terms of the Substitute Subscription Agreement, on the Debenture Issue Date, and the Guarantor agrees to execute and deliver and to cause the Substitute Issuer to execute and deliver the Substitute Subscription Agreement. Holdco agrees and directs that in such circumstances the proceeds from the repayment of the principal amount (but for greater certainty, not the interest) of Note B shall be paid to the Substitute Issuer in full satisfaction of the subscription price for the Substitute Debenture payable by Holdco to the Substitute Issuer.

2.4 Adjustment of Purchased Shares and Purchase Price — Competition Act.

(a) Notwithstanding any other provision hereof, the parties agree the indirect purchase and sale of the Purchased Shares is to be effected as an acquisition of voting shares not notifiable under Part IX of the Competition Act (Canada) (the “Competition Act”) and that the aggregate number of Purchased Shares is not to exceed 20% of the Common Shares outstanding at the Time of Closing (the “Permitted Number of Purchased Shares”). If for any reason the aggregate number of Purchased Shares would exceed or exceeded the Permitted Number of Purchased Shares (the amount by which the aggregate number of Purchased Shares would exceed or exceeded the Permitted Number of Purchased Shares being referred to as the “Excess Number of Purchased Shares”), the number of Purchased Shares shall be reduced by an amount equal to the Excess Number of Purchased Shares and the cash portion of the Purchase Price shall be reduced in the manner provided in section 2.4(b) (the “Purchase Price Reduction”).

(b) If the Purchaser and the Vendors are notified: (i) prior to the Time of Closing, that at the Time of Closing an Excess Number of Purchased Shares will exist, the number of

-7-

Purchased Shares shall be reduced by the Excess Number of Purchased Shares and the Purchase Price payable by the Purchaser to Holdco at the Time of Closing and the principal amount of Note A shall be reduced by the Purchase Price Reduction; or (ii) after the Time of Closing, that at the Time of Closing an Excess Number of Purchased Shares existed, within ten Business Days after the date the Purchaser and the Vendors are so notified (A) the Purchaser shall transfer to Holdco the Excess Number of Purchased Shares and (B) Holdco shall repay to the Purchaser an amount of cash equal to the Purchase Price Reduction. For greater certainty, no decrease in the number of outstanding Common Shares after the Time of Closing which would result in the number of Purchased Shares exceeding 20% of the Common Shares shall give rise to an adjustment hereunder.

2.5 Adjustment of Purchase Price — Price Protection.

(a) If at any time in the nine-month period following the date of this Agreement (the “Price Protection Period”):

	(i)		the Guarantor or any of its Affiliates or any person acting jointly or in concert with the Guarantor makes an offer or proposal to the Corporation respecting, or publicly announces an intention to undertake, an amalgamation or merger with, or an arrangement involving, the Corporation (or other similar transaction) pursuant to which the Guarantor will directly, or indirectly through an Affiliate, or any person acting jointly or in concert with the Guarantor, acquire all or a majority portion of the business of the Corporation; or

	(ii)		the Guarantor or any of its Affiliates or any person acting jointly or in concert with the Guarantor makes an offer or proposal to the Corporation respecting, or publicly announces an intention to undertake, a take-over bid by take-over bid circular in compliance with applicable Canadian securities laws, after giving effect to which the Guarantor, if successful, would beneficially own directly or indirectly through an Affiliate, and together with any person acting jointly or in concert with the Guarantor, a majority of the Common Shares;

(any such transaction being a “Price Protection Transaction”) then within five business days following the completion by the Guarantor or its Affiliate of the Price Protection Transaction the Guarantor will pay, or cause an Affiliate to pay, to the Vendors the Adjustment Payment (as defined below), if applicable, in immediately available funds.

(b) Holdco will be entitled to receive an additional amount on account of each of the Purchased Shares (the “Adjustment Payment”) equal to the amount by which the consideration per Common Share received by the holders of the Corporation’s Common Shares pursuant to the Price Protection Transaction (the “Greater Price”) exceeds the Purchase Price.

(i)

cash, the consideration shall be valued based on the face value of the cash,

-8-

	(ii)		publicly traded securities, the consideration shall be valued based on the closing price of such securities on the date of the completion of the Price Protection Transaction on the published market on which the greatest volume of trading in such securities occurred over the twenty trading days preceding such date,

	(iii)		securities that are not publicly traded until the date of the completion of the Price Protection Transaction, the consideration shall be valued based on the closing price of such securities on the five trading days following the completion of the Price Protection Transaction on the published market on which the greatest volume of trading in such securities occurred over such period, or

	(iv)		any other consideration, the consideration shall be valued at its fair market value as the Vendors and the Purchaser shall mutually agree, acting reasonably.

(d) If all or any portion of the consideration forming the Greater Price has a value expressed in a currency other than Canadian dollars, then the value of that consideration will be expressed in Canadian dollars based upon a conversion rate of exchange equal to the noon spot rate quoted by the Bank of Canada on the date of the completion of the Price Protection Transaction for the purchase of Canadian dollars using the currency in which the consideration (or portion thereof) was originally denominated.

(e) In the event of any disagreement between the Parties with respect to the calculation of the value of the Greater Price, the matter will be submitted to an internationally recognized firm of chartered accountants to be agreed upon by the parties, provided that such firm may not be the auditors of either Brascan or the Guarantor. The decision of such firm of chartered accountants as to the value of the Adjustment Payment will be final and binding on the parties.

SURVIVAL OF REPRESENTATIONS AND WARRANTIES

5.1 Survival of Representations and Warranties.

To the extent that they have not been fully performed at or prior to the Time of Closing, the covenants, representations and warranties of the parties contained in this Agreement and any agreement, instrument, certificate or other document executed or delivered pursuant hereto, except as otherwise expressly provided in any agreement, instrument, certificate or other document executed or delivered pursuant to this Agreement, shall survive the closing of the transactions contemplated hereby until December 31, 2006 and, notwithstanding such closing nor any investigation made by or on behalf of the Purchaser, shall continue in full force and effect for the benefit of the Purchaser, in respect of the Vendors, and for the Vendors in respect of the Purchaser and the Guarantor during such period, except that:

(a) the representations and warranties set out in section 3.2 and section 3.4 shall survive and continue in full force and effect without limitation of time; and

(b) a claim for any breach of any of the representations and warranties contained in this Agreement or in any agreement, instrument, certificate or other document executed or delivered pursuant hereto involving fraud or fraudulent misrepresentation may be made at any time following the Closing Date, subject only to applicable limitation periods imposed by law.

ARTICLE 6

COVENANTS

6.1 Conduct Prior to Closing.

Without in any way limiting any other obligations hereunder, during the period from the date hereof to the Time of Closing, each of the parties hereto shall use its best efforts to take and cause to be taken all necessary corporate action, steps and proceedings to approve or authorize, validly and effectively, the completion of the transactions contemplated hereby.

6.2 Voting of Junior Preference Shares.

From and after the Time of Closing, the Vendors agree that until such time as a nominee of the Guarantor has otherwise been elected or appointed to the board of directors of the Corporation:; (i) they will exercise, or cause to be exercised, the voting rights appertaining to any Junior Preferences Shares beneficially owned from time to time by the Vendors or any other Affiliate of Brascan to nominate and vote for one individual who the Guarantor has, acting reasonably, approved as a nominee to serve as a director of the Corporation; (ii) if requested to

- 16 -

do so by the Purchaser or the Guarantor, they will cause one of their two current nominees serving as a director of the Corporation who is intended to represent the holders of the Junior Preference Shares to resign as a director, unless prior to such request one of the Vendors’ current nominees as a director of the Corporation has already resigned without being requested by the Purchaser or Guarantor to do so, and on not less than 14 days’ prior written notice to the Purchaser and Guarantor, and (iii) prior to any meeting of shareholders of the Corporation at which directors of the Corporation to represent the holders of the Junior Preference Shares are to be elected, the Vendors shall notify the Purchaser and the Guarantor of the time and place of the meeting and the deadline by which the Vendors must exercise, or cause to be exercised, their rights to approve the person for whom the Vendors will vote their Junior Preference Shares for election as a director.

6.3 Standstill and Right of First Offer for Junior Preference Shares.

(a) The Vendors covenant and agree that for a period of 60 days from the Closing Date they will not, and will cause their Affiliates not to sell, transfer, assign or otherwise divest any Junior Preference shares, other than to another Affiliate of Brascan, and thereafter if any Vendor (the “Offeror”) desires to sell directly or through any Affiliate any of the Junior Preference Shares beneficially owned by it (the “Offered Shares”), the Offeror shall deliver a written notice (the “Selling Notice”) indicating such intention to the Purchaser. Such Selling Notice shall set forth (i) the number of Offered Shares the Offeror wishes to sell and (ii) the price per share (the “Offer Price”) which must be a value expressed in Canadian or United States dollars. The Offeror will not be entitled to exercise its rights under this section 6.3 unless all of the Offered Shares to be sold are free and clear of any Encumbrances.

(b) Following the receipt of a Selling Notice, the Purchaser shall be entitled to respond in writing to the Offeror within 48 hours (provided that there are at least two Business Days during such 48 hours). If the Purchaser is willing to purchase all of the Offered Shares, it must state in this written response (a “Purchase Response”) that the Offer Price is acceptable and that the Offeree is willing to purchase all and not less than all of the Offered Shares. If the Purchaser fails to provide a Purchase Response within the required time period in section 6.3(a) then the Purchaser will be deemed to have waived its rights to purchase any of the Offered Shares. For greater certainty, this waiver will not extend to any subsequent Selling Notice.

(c) If the Purchase Response provides, in the aggregate, for the purchase by the Purchaser of not less than all of the Offered Shares at the Offer Price then the Offeror will be deemed to have entered into an agreement of purchase and sale in respect of the Offered Shares. The transaction of purchase and sale will be completed on the seventh Business Day following the expiry of the period provided in section 6.3(b) in accordance with the terms of the Selling Notice.

(d) If the Purchase Response does not provide for the purchase of all of the Offered Shares at the Offer Price then the Offeror shall have the right within 60 days following the expiration of the time period specified in section 6.3(b), to enter into an agreement for the sale to any other person(s) the Offered Shares at a price not less than the Offer Price (and otherwise on the same terms as provided in the Selling Notice); provided that the Offeror may not sell less than all of the Offered Shares except in one or more transactions that are completed contemporaneously resulting in the sale of all of the Offered Shares to third parties. If the

- 17 -

Offeror has not sold all of the Offered Shares to one or more such Persons within the time period specified in this section 6.3(d), the provisions of section 6.3 shall once again apply with respect to the Offered Shares that were not sold.

(A) The Issuer proposes to issue a 4.00 per cent. guaranteed convertible debenture due 2017 in the aggregate paid-up amount of US$375,000,000 (the Debenture). The Debenture will be issued in registered form only without coupons and will be represented upon issue by a single definitive registered debenture (the Definitive Debenture) in a form described in Recital (C). The Debenture will be offered without being registered under the Securities Act in reliance on Regulation S. The Debenture has not been and will not be qualified for sale under the securities laws of any province or territory of Canada. The Debenture is not being offered and may not be offered or sold, directly or indirectly, in Canada or to or for the account of any resident of Canada except pursuant to applicable exemptions.

(B) The Debenture will carry the right to convert into fully-paid 4.00 per cent. exchangeable redeemable preference shares in the Issuer (the Preference Shares), which will be exchanged immediately upon issuance for fully-paid ordinary shares currently of US$0.50 each in the capital of the Guarantor (the Ordinary Shares). Payments and other obligations of the Issuer under the Debenture will be guaranteed pursuant to a guarantee in the same form mutatis mutandis as the guarantee contained in a Trust Deed made between the Issuer (1) the Guarantor (2) and Law Debenture Trustees Limited (3) dated 15 August 2003 in connection with the Existing Convertibles expected to be dated the Closing Date (the Guarantee). The Guarantor will procure the fulfilment of the conversion rights and the share exchange rights pursuant to a deed poll in the same form mutatis mutandis as the Deed Poll executed by the Guarantor dated 15 August 2003 in connection with the Existing Convertibles expected to be dated the Closing Date (the Deed Poll).

(C) Payments in respect of the Preference Shares will also be guaranteed pursuant to the Deed Poll by the Guarantor. The terms and conditions of the Preference Shares will be contained in the articles of association of the Issuer and the resolution of the managing director of the Issuer expected to be passed on or before the Closing Date and expected to be adopted by the shareholders of the Issuer on or before the Closing Date (together, the Articles of the Issuer). The form and terms and conditions of the Debenture (the Terms and Conditions) will be set out in full in the Definitive Debenture and will reflect the principal terms contained in the term sheet set out in Schedule C to the and, subject thereto, and mutatis

mutandis contain the Terms and Conditions and other provisions applicable to the Existing Convertibles.

(D) The Purchaser has agreed to subscribe for the Debenture upon the terms, and subject to the conditions, contained in this Agreement.

Now it is hereby agreed as follows:

1. Definitions and interpretation

1.1 Each word and expression used in this Agreement (including in the Recitals and Schedules to it), except insofar as the context requires otherwise or unless defined elsewhere in this Agreement, has the meaning given to it in Schedule 1.

1.2 This Agreement (and the Recitals and Schedules to it) is to be construed and interpreted in accordance with Schedule 1.

2. Issue and subscription

2.1 On the terms and subject to the conditions of this Agreement, the Issuer agrees to issue the Debenture to the Purchaser and the Purchaser agrees to subscribe and pay for the aggregate principal amount of the Debenture on, in each case, the Closing Date at the Issue Price.

2.2 The Guarantor, pursuant to the terms of the Guarantee, agrees to guarantee all payments in respect of the Debenture and, pursuant to the terms of the Deed Poll, to procure the fulfilment of the conversion rights and share exchange rights in respect of the Debenture and the Preference Shares, subject to, and in accordance with, the Articles of the Issuer, and to guarantee all payments in respect of the Preference Shares.

3. Listing and resale restrictions

3.1 The Debenture will, upon issue, not be listed or quoted on any stock exchange or competent listing authority but, if requested by the Purchaser, the Issuer and the Guarantor agree to use all reasonable endeavours to obtain a listing of, or quotation for, the Debenture (or bonds or debentures identical to the Debenture in all material respects issued in substitution for the Debenture) as soon as reasonably practicable following 14 August 2006 on such stock exchange or competent listing authority in Europe as is commonly used for the quotation or listing of equity-linked debt securities as they may determine. Each party hereto shall be responsible for its own costs in relation to any such listing or quotation.

3.2 The Debenture will be subject to certain resale restrictions under applicable securities laws.
