(C) Mallesons Stephen Jaques SALE AND PURCHASE Agreement sale and purchase 29 July 2004 10 4.5 CONTENTS OF ADJUSTMENT STATEMENT (a) The Adjustment Statement will show the change in each of the items particularised in schedule 7 ("Adjustment Amount") between the amount shown in the Last Accounts and the amount as at the close of business on the Completion Date ("ADJUSTMENT AMOUNT"). (b) As shown in that schedule, in respect of the following items: (i) the working capital calculations under part 1 of schedule 7 ("Adjustment Amount") shall exclude any adjustment on account of the HISmelt deferred revenue liability and any provisions for income tax, retention bonuses under any 2002 Retention Bonus Agreement and obligations under the SEMP, which are payable in connection with the occurrence of Completion; and (ii) the working capital calculations under part 2 of schedule 7 ("Adjustment Amount") shall exclude any adjustment on account of any provisions for income tax, WMC Deferred Revenue and current liabilities under the Facility Agreement but shall include any change in the outstanding balance of the loan under the Facility Agreement; and (iii) both of the working capital calculations under schedule 7 ("Adjustment Amount") shall exclude any costs or liabilities associated with the Pre-Sale Restructure; and (iv) both of the working capital calculations under schedule 7 ("Adjustment Amount") shall include the amount of the estimate of any Income Tax payments for SCP1, CMS GGT and the Australian Branch of the Trust which is agreed under clause 4.5(c) ("Contents of Adjustment Statement"); and (v) the working capital calculation under part 2 of schedule 7 ("Adjustment Amount") shall include an amount of $162,000 as an estimate of the liability of CMS GGT or CMS GTA referred to in clause 4.11(a) ("Further Adjustment"). To avoid doubt, that amount shall not be double counted in the Adjustment Amount (including by way of the making of a provision for an unpaid amount of such GST); and (vi) if Completion does not occur by 30 September 2004 due to the non-satisfaction of the condition precedent in clause 2.1(b) ("adverse notice"), then in respect of any period after 1 October 2004 until the date on which Completion occurs, the Vendor shall not benefit from 45% of the difference between the amount actually payable from WMC Resources Limited under that agreement in respect of that period and the amount which WMC Resources Limited would have been required to pay under that agreement had the tariffs payable by WMC Resources Limited been the A4 Tariff. (c) The agreed estimate in clause 4.5(b)(iv) shall be calculated in the following manner: (C) Mallesons Stephen Jaques SALE AND PURCHASE Agreement sale and purchase 29 July 2004 11 (i) PricewaterhouseCoopers will first calculate an estimate of all of the Income Tax payable by CMS GGT and the Australian Branch of the Trust and the 45% of the Income Tax payable by SCP1 at the Last Balance Date and pro-rated to the Completion Date; and (ii) the calculation by PricewaterhouseCoopers in clause 4.5(c)(i) must be approved by the parties, prior to Completion. To avoid doubt, the calculation approved by the parties under this paragraph (c) shall be conclusive and binding and is not subject to dispute resolution under clause 4.8 ("Disputes"). 4.6 PREPARATION OF ADJUSTMENT STATEMENT The Adjustment Statement will be prepared: (a) in the same format (to the extent applicable) as the Last Accounts and on a basis consistent with the Last Accounts; and (b) in accordance with the same accounting policies, principles and practices as were applied in the preparation of the Last Accounts, applied on a consistent basis and on the presumption that each Target Entity continues as a going concern under the ownership of the Vendor; and (c) to show, in accordance with the sample calculations set out in schedule 7 ("Adjustment Amount") (which are for the period between March 2004 and June 2004), the Adjustment Amount. 4.7 PAYMENT OF ADJUSTMENT AMOUNT Subject to clause 4.8 ("Disputes"), the difference between the Adjustment Amount and the Estimated WCA Amount will be paid by the Buyer to the Vendor (if the Adjustment Amount less the Estimated WCA Amount is a positive amount) or by the Vendor to the Buyer (if the Adjustment Amount less the Estimated WCA Amount is a negative amount) within 60 days of receipt of the Adjustment Statement unless disputed in accordance with clause 4.3(c) ("Adjustment Statement"). An amount payable under this clause 4.7 ("Payment of Adjustment Amount") shall bear interest at the Interest Rate, which accrues daily on the amount of the payment for each day commencing on the Completion Date and ending on the date on which that amount is paid. 4.8 DISPUTES (a) If the Vendor and the Buyer do not agree on all (or part of) an item referred to in the Adjustment Statement within 30 days (or such longer period as they may mutually agree) of the Vendor notifying the Buyer under clause 4.3(c) ("Adjustment Statement") that it disputes that item, then either of them may within a further 14 days refer the disagreement to the Independent Expert with the request that (C) Mallesons Stephen Jaques SALE AND PURCHASE Agreement sale and purchase 29 July 2004 12 the Independent Expert make a decision on the disagreement as soon as practical after receiving any submissions from the Vendor and the Buyer. Those submissions must be made in writing within 30 days (or such other time as may be agreed) after the Independent Expert is appointed. A copy must be made available to each party. (b) The decision of the Independent Expert is, in the absence of manifest error, conclusive and binding on the parties for the purposes of determining the amount payable in respect of the relevant item (or part of it) in determining the Adjustment Amount payable under this agreement. (c) If this clause 4.8 ("Disputes") applies in respect of all or part of any item referred to in the Adjustment Statement, then the amount to be paid under clause 4.7 ("Payment of Adjustment Amount') shall exclude the item (or the relevant part of it) in dispute. Payment in respect of that item (or the relevant part of it) together with interest on that payment shall be made within 7 days after the Independent Expert's report under this clause 4.8 ("Disputes") has been delivered. (d) A payment under paragraph (c) shall bear interest at the Interest Rate, which accrues daily on the amount of the payment for each day commencing on the Completion Date and ending on the date on which that amount is paid. (e) The Vendor and the Buyer agree to share the fees, costs and expenses of the Independent Expert in inverse proportion to the extent to which their respective positions are sustained (for example, if the Vendor's position is 100% sustained, it shall bear none of the fees, costs and expenses of the Independent Expert). (f) The Independent Expert will be appointed as an expert and not as an arbitrator.
