The Purchase Price shall be calculated and paid at the Closing based on the estimated balance sheet of BMT as of the Closing Date attached hereto as Exhibit E (the "Closing Balance Sheet"), and shall be subject to adjustment as provided in Section 2.1(e).

3. Repayment of the Jamaica Loan. The parties agree that BMT shall repay the Jamaica Loan in connection with the Closing, as provided below. Upon such repayment, BMT shall have no further obligation or liability in respect of the Jamaica Loan (including in respect of any portion of the Jamaica Loan Balance that exceeds the Total Agreed Value) and the Intercompany Loan Agreement between Glencore and BMT dated 6 February, 2006 shall terminate and be of no further force or effect.

2. If (A) the Jamaica Loan Balance (after giving effect to any adjustments thereto pursuant to Section 2.1(e)(i)) exceeds the amount paid by BMT under Clause (i) above and (B) as a result of adjustments pursuant to Section 2.1(e)(i) the Total Agreed Value increases, then within three (3) Business Days following resolution of the Relevant Items,

   - 7 -

   Washington Group International shall cause BMT to pay to Seller an amount equal to the lesser of (x) the excess of the Jamaica Loan Balance (after giving effect to any adjustments thereto pursuant to Section 2.1(e)(i)) over the amount paid by BMT under Clause (i) above and (y) the total increase in the Total Agreed Value pursuant to Section 2.1(e)(i). The payment otherwise required by Buyer to Seller under Section 2.1(e)(ii) as a result of such increase in the Total Agreed Value shall be reduced by the amount of the Jamaica Loan repaid pursuant to this Section 2.1(c)(ii).

3. Washington Group International shall contribute, advance or lend, or cause to be contributed, advanced or lent, to BMT immediately available funds in an amount sufficient to fund the repayment of the Jamaica Loan under this Section 2.1(c) but not in excess of an amount equal to the Total Agreed Value.

5. Post-Closing Adjustments.
1. If Washington Group International believes that the Closing Balance Sheet is inaccurate in respect of any item that relates to the Caterpillar Loan Adjustment, the Working Capital Adjustment or the Jamaica Loan Balance (the "Relevant Items"), whether because the Closing Balance Sheet has not been prepared in accordance with IFRS applied on a basis consistent with the balance sheets contained in the Financial Statements (except for any changes thereto required by IFRS) or otherwise, Washington Group International shall notify Seller of that fact within sixty (60) days after Closing, specifying the areas of disagreement and providing evidence in support of its position. The parties will attempt to agree on any adjustments to the Relevant Items within thirty (30) days after Seller receives the notice. In the event that the parties fail to agree in respect of the Relevant Items within such thirty (30) day period, either party may refer the dispute for final determination to PricewaterhouseCoopers or if such designated Person does not accept the assignment, to such other mutually acceptable third party that is an expert in accounting matters and is not affiliated with either Seller or Washington Group International (the "Independent Accounting Firm"). In the absence of mutual agreement on the selection of an Independent Accounting Firm within ten (10) days, either Seller or Buyer may request that the Independent Accounting Firm be appointed by the American Arbitration Association in accordance with applicable rules of the American Arbitration Association. The determination of the Independent Accounting Firm shall be completed within forty-five (45) days following its receipt of the referral under this Section 2.1(e). The Independent Accounting Firm shall not be required to follow any particular rules of procedure, but may adopt such procedures as it, in its sole judgment, shall deem appropriate and expeditious, taking into account the nature of the issues, the amount in dispute and the positions asserted by the parties, it being the intention of the parties to create a flexible, practical and expeditious method for resolving any dispute under this Section 2.1(e); provided that the determination of the Independent Accounting Firm shall be made in accordance with IFRS. The decision of the Independent Accounting Firm

   - 8 -

   shall be final and binding and shall not be subject to review or challenge of any kind. Seller and Washington Group International shall each pay one-half of the fees and disbursements of the Independent Accounting Firm.

2. If the parties' agreement or the Independent Accounting Firm's determination with respect to the Relevant Items pursuant to Section 2.1(e)(i) results in a change in any of the Working Capital Adjustment, the Caterpillar Loan Adjustment or the Jamaica Loan Balance, the Total Agreed Value and the Purchase Price shall be re- calculated to reflect such changes. If the re-calculated Total Agreed Value exceeds the Total Agreed Value calculated based on the Closing Balance Sheet, within three (3) Business Days following resolution of the Relevant Items, (w) subject to Section 2.1(c)(ii), Buyer shall pay to Seller the amount of such difference, by wire transfer of immediately available funds to an account specified in writing by Seller, and (x) Seller shall deliver to Buyer documentation reasonably satisfactory to Buyer evidencing the release of BMT from any Liability in respect of the Jamaica Loan. If the re-calculated Total Agreed Value is less than the Total Agreed Value calculated based on the Closing Balance Sheet, within three (3) Business Days following resolution of the Relevant Items, Seller shall pay (y) the amount of such difference, by wire transfer of immediately available funds to an account specified in writing by Washington Group International, and (z) deliver to Buyer documentation reasonably satisfactory to Buyer evidencing the release of BMT from any Liability in respect of the Jamaica Loan. If the parties' agreement or the Independent Accounting Firm's determination with respect to the Relevant Items pursuant to Section 2.1(e)(i) does not result in a change in the Total Agreed Value, then promptly following resolution of the Relevant Items, Seller shall deliver to Buyer documentation reasonably satisfactory to Buyer evidencing the release of BMT from any Liability in respect of the Jamaica Loan. For avoidance of doubt, a change in the Jamaica Loan Balance alone pursuant to Section 2.1(e)(i) will not result in any payment by Washington Group International or Seller pursuant to this Section 2.1(e)(ii) or any payment by BMT pursuant to Section 2.1(c)(ii).
3. For purposes of calculating the Closing Inventory Adjustment, Closing Inventory (A) has been valued as follows: (1) with respect to spare parts owned by BMT as of March 31, 2006, at the value reflected on the balance sheet included in the March Financial Statements, and (2) with respect to spare parts acquired after March 31, 2006, at the acquisition cost; and (B) based on the inventory count jointly conducted by the parties prior to the Closing, is agreed to have the value indicated for "Inventory" on the Closing Balance Sheet.

(A) If Seller elects to purchase the Put Interests as provided in the immediately preceding sentence, the closing of such purchase shall take place on the fifteenth (15th) Business Day following the date on which Seller makes such election. If Washington Group International has delivered a Put Notice in respect of a Significant Claim Circumstance, the closing of the purchase of the Put Interests shall take place on the fifteenth (15^th) Business Day following the date on which such Put Notice is delivered. At the closing, (x) Seller shall pay the Put Price (as defined below) to Buyer, by wire transfer of immediately available funds to such account as is specified by Washington Group International, and (y) Washington Group International shall cause the transfer and delivery of the Shares and the WGI Loan, if any, to Seller or its designee, in each case, free and clear of all Liens, pursuant to such transfer and assignment instruments as are reasonably acceptable to Seller. From and after such closing, neither Washington Group International nor Buyer nor any of their Affiliates shall have any Liabilities with respect to the Put Interests, and Seller shall indemnify, defend and hold the Buyer Indemnified Parties harmless from and against any and all Losses with respect to the Put Interests. From and after such closing, BMT shall have no Liabilities with respect to the WGI Loan or any portion thereof and shall have no Liabilities to Washington Group International, Buyer or any of their Affiliates with respect to any other Contract or obligation. The parties shall cooperate with each other and shall execute and deliver such documents and instruments and do such other commercially reasonable acts and things as may be reasonably necessary to transfer, or in connection with the transfer of, the Put Interests to Seller, including to acquire any required consent from any third parties, including any Governmental Entities.

(B) If Seller elects to indemnify the Buyer Indemnified Parties in respect an Excess Claim Circumstance, Seller shall indemnify the Buyer Indemnified Parties for the Indemnification Claims on which the Put Notice is based on the terms and conditions set forth in this Agreement, except that Seller's indemnification obligation for such Indemnification Claims shall not be limited to the Final Agreed Cap Value under Section 9.4(a)(iii).

(C) Washington Group International shall cause BMT to continue to operate its business in the Ordinary Course of Business at all times after the Closing and prior to the date on which Washington Group International may no longer deliver a Notice of Claim under this Agreement, and notwithstanding anything to the contrary in this Agreement, the provisions of Section 9.4(a)(iii)(y), this Section 9.4(a)(iv) and Section 9.5(a)(v) shall not apply (but all other provisions of this Section 9.4 shall continue to apply) if BMT's business following the Closing has not been operated in the Ordinary Course of Business since the Closing and, in the event that Seller elects to purchase the Put Interests, continuing until the closing of such purchase (except as otherwise required or permitted below in this Section 9.4(a)(iv)(C)). Without limiting the generality of the foregoing, BMT shall not have (A) incurred any Liabilities outside

- 25 -

the Ordinary Course of Business, including any Liabilities for indebtedness for borrowed money or as a guarantor of any obligations of any third party (it being understood that indebtedness for borrowed money obtained in arms'-length transactions and used in the Ordinary Course of Business to acquire mining equipment or to refinance such indebtedness shall not by itself be deemed outside the Ordinary Course of Business), or (B) disposed of any assets other than in the Ordinary Course of Business in arms'-length transactions, except that BMT may, in its sole discretion, transfer to any one or more third parties, or otherwise dispose of, whether in or outside the Ordinary Course of Business, any assets that are not used in connection with its performance of either of the Mining Contracts. Prior to, and as a condition to, the closing of the purchase of the Put Interests, BMT shall transfer to one or more third parties, whether in or outside the Ordinary Course of Business, all Liabilities that do not relate to, have not arisen from or are not required for its performance of the Mining Contracts in the Ordinary Course of Business, on the basis that BMT is released from all such Liability. Any actions taken by BMT in accordance with the Mining Contracts (or any amendment thereto) or at the direction of Windalco (whether pursuant to the Mining Contracts, any amendment thereto, or otherwise) shall be deemed to be in the Ordinary Course of Business for purposes of this Section 9.4(a)(iv)(C).

(D) Nothing in this Section 9.4(a)(iv) shall affect or be deemed to affect the Survival Period for any matter for which the Buyer Indemnified Parties may seek indemnification under this Agreement.

5. As used in this Agreement, "Put Price" means an amount equal to: (A) the Final Agreed Cap Value, less all amounts previously paid or otherwise borne by Seller pursuant to its indemnification obligations under Sections 8.3(a) and 9.3 (exclusive of any interest, penalties, attorneys' fees, accounting fees and investigation costs included within such previous payments), plus (B) the positive difference (if any) of (1) the total amount of the Caterpillar Loan (including principal, interest and any other fees) that was repaid after the Closing Date from cash made available by Washington Group International, the Buyer or any of their Affiliates to BMT, whether as loans or capital (the "Funded Repaid Amount"), minus (2) the total amount of all payments or distributions made by BMT to Washington Group International, the Buyer or any of their Affiliates after the Closing in respect of the capital stock of BMT (including dividends) or loans (including the WGI Loan) made to BMT by Washington Group International, the Buyer or any of their Affiliates and the proceeds of all loans made by BMT to Washington Group International, the Buyer or any of their Affiliates up to a maximum aggregate amount equal to 50% of the Funded Repaid Amount, plus (C) the book value on the date of the closing of the sale and purchase of the Put Interests of all assets acquired by BMT after the Closing, determined in accordance with Article 10 of Exhibit C of the Kirkvine Mining Contract in the case of assets used in connection with the performance of the Kirkvine Mining Contract and in accordance with Article 10 of Exhibit C of the Ewarton Mining Contract in the case of assets used in connection with the performance of the Ewarton Mining Contract, minus (D) all Liabilities of BMT in respect of indebtedness for borrowed money (including all vendor and other financings of the assets referred to in the preceding clause (C)) incurred after the Closing and outstanding on the date of the closing of the sale and purchase of the Put Interests (other than the WGI Loan). "Caterpillar Equipment" means assets that are owned by BMT as of the date of the closing of the sale and purchase of the Put Interests and that had been financed with the Caterpillar Loan.

2. Netting of Insurance Proceeds. No indemnified party shall be entitled to indemnification for any Losses (a) unless and until such indemnified party or, if such indemnified party is not a party hereto, the party hereto through whom the indemnified party derives its rights to indemnification, and its Affiliates have taken reasonable steps to pursue all claims for insurance available with respect to those Losses and (b) to the extent of the amount of insurance recovered by such party or its Affiliates with respect to those Losses.
3. Tax Savings. Any amount which would be recoverable by a Seller Indemnified Party under Section 8.3 or this Article 9 as a result of Losses suffered by it shall be reduced (or if applicable, reimbursed to Washington Group International) to the extent of the aggregate cash benefits (whether in the form of actual reductions in Taxes payable or Tax credits) realized by the Seller Indemnified Party as a result of the deduction of such Losses. Any amount which would be recoverable by a Buyer Indemnified Party under Section 8.3 or this Article 9 as a result of Losses suffered by BMT shall be reduced (or if applicable, reimbursed to Seller) to the extent of the aggregate cash benefits (whether in the form of actual reductions in Taxes payable or Tax credits) realized by BMT as a result of the deduction of such Losses.

9.5    Procedures.

1. Notice of Claim; Information. Promptly after obtaining knowledge of any facts that have given rise to, or could reasonably give rise to, a claim for indemnification under Section 8.3 or this Article 9 (an "Indemnification Claim"), including Indemnification Claims satisfying the De Minimis Threshold (whether or not the Basket has been reached), an indemnified party shall give written notice to the indemnifying party of such Indemnification Claim ("Notice of Claim"); provided, however, that the failure to give a Notice of Claim to the indemnifying party shall not relieve the indemnifying party from any liability that it may have to an indemnified party hereunder except to the extent the indemnifying party is prejudiced by such failure. The Notice of Claim shall set forth the amount (or a reasonable estimate, if then practicable) of the Losses suffered, or which may be suffered, by an indemnified party as a result of such Indemnification Claim. The indemnified party will furnish to the indemnifying party such information (in reasonable detail) it may have with respect to such Indemnification Claim (including copies of any summons, complaint or other pleading that may have been served on it and any written claim, demand, invoice, billing or other document evidencing or asserting the same). A Buyer Indemnified Party may give a Notice of Claim in respect of an Indemnification Claim arising under Section 8.3 only if (x) such Indemnification Claim by itself satisfies the De Minimis Threshold, or (y) such Notice of Claim is submitted together with one or more other Notices of Claim in respect of Indemnification Claims arising under Section 8.3 and together the Indemnification Claims covered by all such Notices of Claim aggregate to an amount equal to or in excess of the De Minimis Threshold, or (z) no Buyer Indemnified Party has given a Notice of Claim in respect of an Indemnification Claim under Section 8.3 during the preceding twelve month period; provided, however, that (i) the foregoing restriction shall not apply if it would result in a Notice of Claim being given after the end of the Survival Period for the Indemnification Claim that is the subject of such Notice of Claim, and (ii) the delay required by this sentence shall not be deemed to violate the requirement of the first sentence of this clause (a) that the Buyer Indemnified Party shall give the applicable Notice of Claim promptly after obtaining the facts in respect of the related Indemnification Claim.

- 27 -

2. Right to Defense. In the event any claim set forth in the Notice of Claim is a claim asserted against an indemnified party by a third party, upon delivery by the indemnifying party to the indemnified party of written notice, the indemnifying party may assume and control the defense thereof with counsel of its choice reasonably acceptable to the indemnified party, and thereafter the indemnifying party will not be liable to the indemnified party hereunder for any fees of other counsel subsequently accrued by the indemnified party in connection with the defense thereof so long as the indemnifying party is conducting such defense actively and diligently. In the event a Notice of Claim is delivered under this Article 9, so long as there is no actual or reasonably anticipated conflict, the indemnifying party and the indemnified party will cooperate fully with each other, at the indemnifying parties' cost and expense, in connection with the defense, negotiation or settlement of the claim covered by such Notice of Claim. If the indemnifying party assumes the defense of an action, (a) the indemnified party will be entitled to participate therein at its sole cost and expense and (b) no settlement or compromise thereof which involves an admission of guilt or liability on the part of the indemnified party or which does not include a full and unconditional release of the indemnified party in connection with the subject matter of the action may be effected by the indemnifying party without the consent of the indemnified party. If the indemnifying party does not assume the defense of an action or has assumed such defense but is not conducting such defense actively and diligently, (i) the indemnified party may defend, compromise or settle the action in any manner it may deem appropriate (and the indemnified party need not consult with, or obtain any consent from, the indemnifying party in connection therewith), (ii) the indemnifying party will reimburse the indemnified party promptly and periodically for the costs of defending against such action (including attorneys' fees and expenses), and (iii) the indemnifying party will remain responsible for any Losses the indemnified party may suffer resulting from, arising out of, relating to, or caused by such action to the fullest extent provided in this Article 9. The parties acknowledge that (x) an indemnifying party shall not have failed to assume the defense of an action or to actively and diligently conduct such a defense solely because it has requested or expressly permits the indemnified party to conduct and oversee the day-to-day defense of the action, but (y) in the event of such request or express permission, the preceding sentence shall nonetheless apply, except that the indemnified party shall keep the indemnifying party reasonably informed of the status and progress of the matter, and shall not agree to any settlement or compromise thereof without the prior consent of the indemnifying party.

9.6    Exclusive Remedies. From and after the Closing, except in the case of fraud and except as provided in Article 8 and Section 10.12, the parties' right to indemnification under this Article 9 with respect to any Losses shall be its sole and exclusive remedy for damages under or with respect to this Agreement or the transactions contemplated hereby, and it shall not be entitled to pursue, and hereby expressly waives, any and all rights that may otherwise be available either at law or in equity with respect thereto. Without limiting the generality of the foregoing, subject to the exceptions referred to in the immediately preceding sentence, each party waives to the fullest extent permitted by law any claim or cause of action which it might otherwise assert, including under the common law or federal or state securities, trade regulations or other Laws, by reason of this Agreement or the transactions contemplated hereby, except for claims and causes of action brought pursuant to this Article 9.
