                 ACCC shall pay all reasonable costs relating to the formation and qualification of the Partnership and
the transfer of assets, obligations and liabilities of the Business to the Partnership. Such costs shall include, but not be limited to, reasonable fees and expenses of counsel and other advisors to MPCo and the Partnership (and GP); transfer tax
and non-recoverable GST/QST incurred or assessed on MPCo and the Partnership (and GP) for such activities; all costs to transfer permits, contracts or authorizations of MPCo to the Partnership and/or GP or to issue, sign or obtain permits, contracts
or authorizations in replacement of existing ones or which become required under applicable laws as a result of the transfer of the Business to the Partnership; and all costs of any compliance obligations arising as a result of the transfer of the
Business to the Partnership or as a condition of the transfer of the Business to the Partnership, including without limitation such costs associated with (i) investigations (including as to the existence of acquired rights) as to any
requirement for permits, contracts or authorizations and applications for the issuance of permits or authorizations, (ii) studies, surveys, contracts, servitudes, filings, inquiries, reports required to effect the transfer of or as a condition
of transfer or new permits, contracts or authorizations or to determine if a permit, contract or authorization is required, and (iii) measures or works (including characterization, rehabilitation or monitoring work) to be implemented as a condition
of, or  pursuant to, transfer or new permits, contracts or authorizations. For greater certainty, such costs shall not include any costs attributable to the condition of the assets existing prior to the transfer of the Business to the
Partnership, where such condition is not in compliance with Environmental Laws while not benefitting from acquired rights, and any costs required to correct any existing defect in title to the immovable property.  Such excluded costs will be
paid by the Partnership. "Environmental Laws" shall mean applicable laws and regulations pertaining to the environment and its protection and ground water criteria in the Politique de protection des sols et de réhabilitation des terrains
contaminés (Quebec).

 2.2              
 Reimbursement of Professional Fees Incurred by Alcoa . 

	 	2.2.1	ACCC shall pay the professional fees and disbursements (including attorneys' fees and actuaries' fees and extra-judicial fees and expenses) incurred by Alcoa (or any fees of their Affiliates) in connection with the Proposed
Transactions (even if the Proposed Transactions are not consummated), including fees for assessing liability exposure and fees for tax structuring and for determining, validating and implementing permitting requirements (including those described in
Section 2.1). Such reimbursement is subject to the following conditions: 

	 	 	 	 
	 	 	(a)	Reasonable fees and disbursements shall be reimbursed only to the extent that they are incurred in connection with the Proposed Transactions, provided however that ACCC shall not reimburse Alcoa (or any of their Affiliates)
 for fees and disbursements incurred in connection with the agreements which shall be entered into between HQ Énergie and Alcoa in connection with the HQ Acquisition, including the limited partnership agreement of the Partnership and any
shareholders agreement among the shareholders of GP; 
	 	 	 	 
	 	 	(b)	Fees and disbursements shall be reimbursed up to a maximum amount of $2 
million (the "Cap"), exclusive of GST and QST, provided that if Alcoa expects such fees and disbursements to exceed the Cap, Alcoa shall advise ACCC which shall use its commercial reasonable efforts to obtain the required approvals from the Monitor
 and, if applicable, the Court overseeing the Restructuring, to pay such additional fees and disbursements. The Cap is premised on the Proposed Transactions closing on or before December 31, 2009; if the Proposed Transactions do not close by
December 31, 2009 or if there is a material change in the scope of the Proposed Transactions, then Alcoa may reasonably reassess the appropriateness of the Cap and require a reasonable increase thereof as a condition to proceeding with the Proposed
Transactions; and
	 	 	 	 
	 	 	(c)	Copies of invoices are provided on a monthly basis to ACCC (provided that Alcoa may redact from such invoices entries that they reasonably consider to be subject to attorney-client privilege). 
	 	 	 	 
	 	2.2.2	Fees and disbursements that meet the above conditions shall be paid by ACCC in full within 15 days of the presentation of the invoices therefor. Alcoa may present the first such invoices at any time and
from time to time after signature of this Agreement. 
	 	 	 	 
	2.3	Indemnification. 
	 	 	 	 
	 	2.3.1	Without limitation to rights available at law, effective at the closing of the Proposed Transactions, ACCC and ACI hereby solidarily (ACCC and ACI hereby waiving the benefit of division and discussion)
agree to indemnify and save Alcoa Canada, Alcoa Ltd., their Affiliates (including Alcoa Inc. and Newco) and their current and former officers and directors (the "Alcoa Indemnified Persons"), and the Partnership, GP, its current and former
officers and directors, and the current and former officers and 

    
 
 -7-

	 	 	directors of MPCo (the "MPCo Indemnified Persons"), harmless from and against any damages, expenses, costs, losses, interest and penalties suffered by, imposed upon or asserted against any of the
 Alcoa Indemnified Persons or the MPCo Indemnified Persons as a result of, in respect of, connected with, or arising out of, under or pursuant to any of: 

	 	 	 	 
	 	 	(a)	any liability of MPCo, the Partnership, GP and their current officers and directors, whether actual or contingent, for any pension funding obligation or pension deficit related to any pension plan sponsored by ACCC
 or any of its Affiliates, including without limitation the Régime de retraite à prestations déterminées des employés non syndiqués d'Abitibi-Consolidated Inc. and the Régime complimentaire de retraite
des employés non syndiqués de Donohue Inc. or any predecessor pension plan thereto (such two named plans and any predecessor to such two plans are referred to herein as the "Plans"), other than any funding obligation which
directly relates to persons that are or were directly employed by MPCo in respect of the pensionable service of such employees and former employees accrued while directly employed by MPCo prior to the date of the closing of the Proposed Transactions
(the "Contingent Pension Liabilities") . For greater certainty, the definitive agreements to be entered into to effect the Proposed Transactions may include provisions for the transfer of assets and liabilities in
respect of the employees and former employees of MPCo from the ACCC Plan to a successor pension plan and any additional funding to reduce or eliminate a deficit in connection with such a transfer shall be borne proportionately by ACCC and Alcoa in
proportion to their respective interests in MPCo as at the date hereof in a manner to be agreed by ACCC and Alcoa, acting reasonably; 
	 	 	 	 
	 	 	(b)	any claim by any person attacking the validity of all or part of the Proposed Transactions including under the Companies Act (Quebec) and under insolvency legislation (or insolvency or creditors' rights related
 provisions within any other laws), including the CCAA, the Bankruptcy and Insolvency Act, the Canada Business Corporations Act and the Civil Code of Québec; 
	 	 	 	 
	 	 	(c)	the Proposed Transactions, other than as a direct result of such indemnified person's gross or willful misconduct and then only to the extent thereof; 
	 	 	 	 
	 	 	(d)	with respect to Alcoa Indemnified Persons only (but for greater certainty, including the proportion attributable to Alcoa by reason of its 40% ownership interest in MPCo and the Partnership arising from claims against
 MPCo or MPCo Indemnified Persons), any claims, claims for losses (including loss of profit), liabilities, costs and expenses (including all reasonable legal and other professional fees and disbursements, interest, penalties and amounts paid in
settlement) that any Alcoa Indemnified Person may incur or suffer in connection with (i) the failure of the Partnership to obtain, whether by issuance or transfer, any required permit, contract or authorization or (ii) the loss or
revocation of any acquired rights, any permit, contract or authorization held by MPCo or its ceasing to be in good standing; in each case as a result of the transfer of the Business to the Partnership or as a result of the Proposed Transactions; and

  
 
  
 -8-

	 	 	(e)	all Canadian or US federal, provincial, state or local income tax, capital tax, transfer tax, land transfer taxes and non-recoverable sales taxes (including non-recoverable Goods and Services Taxes and non-recoverable
 Quebec Sales Taxes) to any Alcoa Indemnified Person, GP or the Partnership as a direct result of the Proposed Transactions (the "Taxes") (as computed based on the principles set out in Section 2.4.1(e)). Any amount
payable pursuant to this Section 2.3.1(e) shall be grossed up to include tax, if any, payable by the indemnified person as a result of such indemnification payment such that the net after-tax amount
received by such indemnified person is equal to the full amount of the Taxes. T he amount payable under this Section 2.3.1(e) shall be further computed based on the principles set
out in Section 2.4.1(b) unless the payment to be made under this Section  2.3.1(e) is as a result of an assessment disallowing the deduction provided by the
election referred to in Section 2.4.1(b). An amount shall be payable under this Section 2.3.1(e) only if it arises from an assessment duly issued by a tax authority that is not
subject to objection or appeal or a decision of a competent tribunal that is not subject to appeal. Alcoa shall give written notice to ACCC promptly (and, in any event, within 20 business days) after receipt by an Alcoa Indemnified Person of any
proposed tax assessment or tax adjustment, from any tax authority in respect of a tax liability which may give rise to a claim under this Section 2.3.1(e) (a "Tax Assessment"). Such notice must set
out the information with respect to, and include a copy of, the Tax Assessment that is then available to the Alcoa Indemnified Person. ACCC or ACI shall have the right to undertake and control any proceedings, objection or other defence (a "Tax
Proceeding") of any Tax Assessment and, in such case, ACCC or ACI shall pursue any such Tax Proceedings in a timely manner and in good faith. Alcoa shall provide ACCC with such information with respect to the tax liability as may become
available to the relevant Alcoa Indemnified Person and Alcoa shall cooperate with ACCC or ACI, as the case may be, in the conduct of all Tax Proceedings relating to any Tax Assessment and related inquiries or investigations. If an amount is payable
under applicable tax legislation as a result of a Tax Assessment notwithstanding the contestation of such Tax Assessment, ACCC or ACI shall remit the amount so payable to the relevant Alcoa Indemnified Person for remittance to the taxation
authorities. Following the final result of any Tax Proceeding, any refund of Taxes, including an amount covered by the previous sentence, received by an Alcoa Indemnified Person shall be refunded to ACCC or ACI, as the case may be, within 30 days of
receipt together with any interest received thereon. 
	 	 	 	 
	 	2.3.2	At closing of the Proposed Transactions, ULC shall solidarily guarantee ACCC's and ACI's obligations under this Section 
2.3 to the beneficiaries of such obligations, and waive the benefit of division and discussion. 
	 	 	 	 
	2.4	Payment on Account of Tax at Closing. 
	 	 	 	 
	 	2.4.1	At closing of the Proposed Transactions, ACCC or ACI shall pay through an irrevocable direction of payment to HQ Énergie to make said payment
 from the proceeds otherwise payable to ACCC pursuant to the HQ Acquisition to the appropriate Alcoa Indemnified Person an amount equal to the Taxes calculated on 

  
 
 -9-

	 	 	the basis described below . Any amount payable pursuant to this Section 2.4.1 shall be grossed up to include tax payable, if any, by the appropriate Alcoa
Indemnified Person as a result of such indemnification payment such that the net after-tax amount received by the appropriate Alcoa Indemnified Person is equal to the full amount of the Taxes. Such Taxes shall be computed based on, among other
things, 
	 	 	 	 
	 	 	(a)	(i) the Private Letter Ruling referred to in Section 1.4(b), or if no such ruling is obtained, the opinions as to US tax matters referred to in Section 
1.3(d), and (ii) the opinions as to US tax matters referred to in Section 
1.3(e), it being understood that, if the Internal Revenue Service issues a negative ruling as part of the Private Letter Ruling referred to in Section  
1.4(b) on the US tax matter referred to in Section  1.3(e), or if the conditions in Section 
1.4(d) are waived by ACCC because a favourable opinion cannot be obtained, the amount payable under this Section 
2.4 shall include the tax payable by the appropriate Alcoa Indemnified Person on the deemed dividend referred to in Section 1.3(e); 
	 	 	 	 
	 	 	(b)	the filing of an election under Subsection 12(2.2) ITA (and any provincial equivalent), if relevant, to reduce the aggregate amount payable under this Section 2.4.1;

	 	 	 	 
	 	 	(c)	the computation by Deloitte & Touche of the safe income attributable to the MPCo shares owned by Alcoa; 
	 	 	 	 
	 	 	(d)	the valuations performed by Deloitte & Touche of the (i) V-Day value of the MPCo shares owned by Alcoa, (ii) the fair market value of such shares at the time of closing, and (ii) the fair market value of the 40%
 partnership interest to be acquired by Alcoa under the Proposed Transactions; 
	 	 	 	 
	 	 	(e)	if the amount of Taxes resulting from the Proposed Transactions is reduced as a consequence of the utilisation by Alcoa Canada, Alcoa Ltd., their Affiliates (including Alcoa Inc.) of tax attributes, including capital
 cost allowance, capital losses and non-capital losses then, subject to the following, the amount payable under Sections 2.4.1 and 2.3.1(e) shall be determined as if no tax attributes were so utilized.
Notwithstanding the foregoing, if the Proposed Transactions are otherwise neutral or positive for Alcoa Ltd. with respect to the computation of its deferred taxes under US GAAP (i.e. they will increase/not reduce Alcoa
Ltd.'s deferred tax asset position or they will reduce/ not increase Alcoa Ltd.'s deferred tax liability position) then Alcoa Ltd. shall utilize its net capital losses available at the end of its 2008 taxation year  to reduce the amount of
Taxes otherwise payable as a result of the Proposed Transactions and the amount payable under Sections 2.4.1 and 2.3.1(e) shall be computed after taking into account the use of such net capital losses of
Alcoa Ltd. (subject to any successful adjustment of such available losses by the tax authorities) and without any compensation payable to any Alcoa Indemnified Person for the use of such capital losses, provided however that the amounts payable
under Sections 2.4.1 and 2.3.1(e) may only be reduced by an amount not to exceed the amount attributable to such losses (subject to any successful adjustment of such available losses by the tax authorities) and included 

 
 
 -10-

	 	 	 	in the current deferred tax asset or liability position of Alcoa Ltd. and which is replaced in the deferred tax asset or liability position of Alcoa Ltd. by an increase of (i) tax depreciation indirectly available to Alcoa Ltd. with
respect to the assets transferred to the Partnership as a result of the Proposed Transactions or (ii) tax basis in the Partnership interest to be held by Alcoa.
	 	 	 	 
	 	2.4.2	 	 
	 	 	 	 
	 	 	(a)	If any of the items in Sections 2.4.1(c) and 2.4.1(d) above result in uncertainty as to the amount of Taxes payable under Section 
2.4.1, then such Taxes shall be computed based on a reasonable tax treatment of such items as determined by ACCC and agreed to by Alcoa. 
	 	 	 	 
	 	 	(b)	The parties agree to file all relevant tax returns based on the amount of Taxes determined under Section 2.4.1 and the items in Sections 2.4.1(a) to 2.4.1(d)

million "ACI DIP charge" as set forth in paragraph 89 of the Court Order dated May 6, 2009 (the "May 
6 Order"), secured by the same assets as the "ACI DIP Charge" and with the same guarantors and obligors then securing the "ACI DIP Charge", shall be deemed to be satisfactory to Alcoa if the ULC DIP Loans are approved by an order of the Court and such
order contains provisions that protect the priority of the ULC DIP Loans substantially similar to paragraphs 61.9 and 93 of the May 6 Order), (ii) cash or cash equivalents, or (iii) such other assets as may be agreed to by
ACCC and Alcoa, acting reasonably. 
	 	 	 	 
	 	2.5.4	ACI and ACCC undertake not to cause the distribution of any assets from ULC or the continuation in another jurisdiction, winding-up, dissolution, amalgamation or other combination of ULC with any other person
for so long as ULC holds assets pursuant hereto, provided that ULC shall have the right to make distributions if such distributions would not cause the value of the Permitted Investments retained by ULC to be less than the amounts set forth in
Sections 2.5.1(a) and 2.5.1(b), taking into account the release of such amounts pursuant to this Agreement. 
	 	 	 	 
	2.6	Duration of Asset Retention Undertakings. 
	 	 	 	 
	 	2.6.1	The undertakings in Section

2.5.1(a), less the amounts, if any, determined pursuant to Sections 
2.6.1(b) (current service) and 2.6.1(c) (special payments) shall be released by ULC, and following the "successful completion of the Restructuring" amounts equal to the amounts
 paid in accordance with Section 2.6.1(d) and 2.6.1(e), if any, upon each such payment being made shall be released by ULC until the net assets so retained pursuant
to Section 2.5.1(a) have all been released; and 
	 	 	 	 
	 	 	(b)	the amount, if any, in respect of current service contributions due to the Plans by ACCC and Affiliates (other than ULC), shall be equal to the excess, if any, of (i) the current service contributions due under the
Plans in respect of  pensionable employment by participants therein up to the end of the month in which the Proposed Transactions close, over (ii) the current service contributions actually remitted to the Plans in respect of  pensionable
employment by participants therein up to the end of the month in which the Proposed Transactions close ; and 

  
 
 -12-

	 	 	(c)	the amount, if any, in respect of special payments due to the Plans by ACCC and its Affiliates (other than ULC), shall be equal to the excess, if any, of:
	 	 	 	 	 
	 	 	 	(i)	the special payments due under the Plans up to the end of the month in which the Proposed Transactions close, over
	 	 	 	 	 
	 	 	 	(ii)	such special payments actually remitted to the Plans, 
	 	 	 	 	 
	 	 	 	provided that in the event that prior to, coincident with or following the "successful completion of the Restructuring", the obligation to make any such special payments is reduced or eliminated (and
not imposed upon any Alcoa Indemnified Persons or MPCo Indemnified Persons), then the amount in Section 2.6.1(c)(i) shall be deemed to be reduced by an amount equal to such reduction of the
obligation, or eliminated if such obligation is entirely eliminated; and   
	 	 	 	 	 
	 	 	(d)	upon a payment following the "successful completion of the Restructuring" by ACCC and its Affiliates (other than ULC) to the Plans of all or a portion of the current service contributions, if
any, remaining due to the Plans in respect of pensionable employment by participants therein up to the date on which the Proposed Transactions close, an amount equal to each such payment shall be released by ULC; and 
	 	 	 	 	 
	 	 	(e)	upon a payment following the "successful completion of the Restructuring" by ACCC and its Affiliates (other than ULC) to the Plans of all or 
 a portion of the special payments, if any, remaining due to the Plans up to the date on which the Proposed Transactions close, an amount equal to each such payment shall be released by ULC, 
	 	 	 	 	 
	 	 	provided, however, that if any claims against any of ULC, MPCo, Alcoa or the Partnership for Plan deficits have been made or threatened on or prior to the date of any such release, then
 an amount equal to the lesser of (i) the amounts retained on such date by ULC pursuant to Section 2.5.1(a) against which no other claims are pending and (ii) the amount of such claims or threatened claims shall
continue to be retained by ULC until resolution of those claims or threatened claims. 
	 	 	 	 	 
	 	2.6.2	For the purposes of this Section, the "successful completion of the Restructuring" means a plan of arrangement has been accepted by the requisite majority of the creditors of ACCC and its Affiliates
under the CCAA and sanctioned by a court of competent jurisdiction and (ii) an order has entered in the Chapter 15 Cases recognizing or enforcing such CCAA plan in the Chapter 15 Cases, or the Chapter 15 Cases have otherwise been closed or
terminated, in such case in a manner that no person has a further right of appeal, and which plan does not purport to compromise any person's obligations under this Agreement or the definitive agreements implementing the Proposed Transactions.

  
         
 
 -13-

	 	2.6.3	The undertaking in Section 2.5.1(a) shall terminate or be proportionately reduced or increased upon (a) a final non-appealable determination of the applicable regulatory
authority, (b) the adoption of legislation, or (c) the final determination by a judgment of a court of competent jurisdiction (with all appeal rights to such judgment having expired) of the quantum, if any, of the liabilities for which ACCC, MPCo
and ULC, as applicable, have agreed to indemnify the Alcoa Indemnified Persons and the MPCo Indemnified Persons pursuant to Section 2.3.1(a). Such amount shall not be reduced however below the amounts required to be kept
pursuant to Sections 2.6.1(b) and 2.6.1(c). 
	 	 	 	 	 
	 	2.6.4	Assets having a value equal to the amount set forth in: 
	 	 	 	 	 
	 	 	(a)	Section 2.5.1(b)(i) shall be released on the later of the fourth anniversary of the last of the Proposed Transactions (other than the dissolution of MPCo) to be effected and the date on
which assets are released under Section 2.6.4(b); 
	 	 	 	 	 
	 	 	(b)	Sections 2.5.1(b)(ii) and (iii) shall be released 90 days after the expiration of the latest date on which an assessment, reassessment or other form of recognized document
 assessing liability for tax, interest or penalties under applicable tax legislation could be issued under such tax legislation to Alcoa Inc. or Newco for the taxation year of Alcoa Inc. or Newco during which the Proposed Transactions (other than
the dissolution of MPCo) occur, as such period may be extended by any consent or waiver given in respect thereof (the "Tax Assessment Periods"). After the implementation of the Proposed Transactions, the parties will determine if it is
advisable to request that the Canada Revenue Agency perform a "real time audit" thereof. Provided that such a request would only be made if it results in an acceleration of the termination of the undertaking under Section 2.5.1(b)(ii) related to the indemnity provided for in Section 2.3.1(e); 
	 	 	 	 	 
	 	 	provided, however, that if any claim against any of the Alcoa Indemnified Parties or the MPCo Indemnified Parties with respect to matters provided in Sections 2.1, 2.2, 2.3.1(b), 2.3.1(c), 2.3.1(d) and 2.3.1(e) have been made or threatened on or prior to the date of any such release, then an amount equal to the lesser of (i)
the amounts retained at such time by ULC pursuant to Section 2.5.1(b) against which no other claims are pending, and (ii) the amount of such claims or threatened claims, shall be retained in the form of "Permitted Investments" by
ULC until resolution of those claims or threatened claims. 
	 	 	 	 	 
	 	2.6.5	No release of net assets or the security provided thereon under this Section 2.6 shall diminish or extinguish indemnification obligations of any party to this Agreement, all
of which indemnification obligations shall survive for the longest periods permitted by law. 
	 	 	 

	 	2.6.6 	As long as ULC shall be subject to the asset retention undertaking in Section 2.5.1, ULC's sole activities shall be restricted to holding "Permitted Investments", as provided in this
Agreement, and it shall have no other assets or liabilities other than as provided in this Agreement. 

          
          
 
 -14-

	2.7	Reimbursement of Overpayment. 

                   If at the
latest of (i) the end of Tax Assessment Periods or (ii) the time a Tax Proceeding, if any such proceeding commences before the time referred to in (i), is finally determined and is not subject to appeal or revision, the relevant Alcoa Indemnified
Person determines, acting in good faith, that the amount paid to such relevant Alcoa Indemnified Person pursuant to Section 2.4.1 is greater than the total amount of Taxes, interest and penalties paid by or ultimately
assessed against such Alcoa Indemnified Persons as a result of the Proposed Transactions or that would have been paid or ultimately assessed against such Alcoa Indemnified Persons but for the use of tax attributes (other than net capital losses of
Alcoa Ltd. available at the end of its 2008 taxation year) by it that were not credited pursuant to the first sentence of Section 2.4.1(e), then the relevant Alcoa Indemnified Person shall promptly reimburse ACI or ACCC,
whichever makes the payment under Section 2.4.1 at closing (or any person designated by ACI or ACCC) the difference, less the amounts, if any, required to satisfy the tax gross up rights of Alcoa, the whole subject to the
status of any outstanding claims among such parties at such time.

 EXHIBIT  A - PROPOSED TRANSACTIONS 
 (See document attached entitled "Project Uranium - simplified step plan" dated September 2, 2009)

   
   PROPOSED STEPS FOR PAYMENT INTERCOS OF MPCo  
  Note: The amounts indicated in the following steps are based on management estimates of the amounts of the intercompany payables forecasted as at September 30, 2009. These steps will need to be updated to reflect
the amounts which will be outstanding on the closing date. The amounts below do not constitute an agreement that these amounts are accurate.  
  Prior to closing, the following step will occur:
 
  1.                        ACCC will reimburse MPCo the Electricity and Taxes amount invoiced up to such time such that the remaining outstanding balance on the ACCC Intercos shall be equal to the ACCC Electricity & Taxes amount. As such,
MPCo's Line of Credit will decrease by approximately $173,000. 
  2.                        The ACCC Intercos and the ACCC Electricity & Taxes will be repaid by
compensation. 
  At closing, the following steps will occur:  
  3.                        ACCC will transfer its rights under the ACCC Loan to ACI in consideration for
the issuance by ACI of a promissory note to ACCC for an amount equal to the ACCC Loan or other form of consideration acceptable to ACCC. 
  4.                       Newco* will compensate ACCC for 40% of the accrued taxes of MPCo
prior to closing date, such taxes to be computed including the amount of the capital tax and deducting the amount of capital cost allowance which would have accrued in 2009 up to the date of the closing of the Proposed Transactions but for the
wind-up of MPCo before its year end (it being understood that 100% amount of such taxes after inclusion of the capital tax and deduction of the capital cost allowance is estimated at approximately $150,000 as at September 30, 2009). This amount will
be applied in reduction or set off of the amount to be paid to Alcoa pursuant to Section 2.4.1 of the Implementation Agreement.  
  5.                        The Partnership will, in connection with the sale of the business of MPCo by
ACCC to the Partnership [i.e. step 9 of the Deloitte step memo], assume the obligations under the Lac Ste-Anne Claim, the ACCC Loan and the amounts owed under the CIBC Line of Credit. In connection with such transfer, any remaining cash on hand of
MPCo as well as all accrued receivables from Alcoa, including the Alcoa Intercos, will also be transferred to the Partnership. 
  6.                        HQP will purchase a 60% interest in the Partnership and GPCo from ACCC
[i.e. steps 11 and 12 of the Deloitte step memo]. The consideration payable by HQ Énergie to ACCC will be reduced by an amount equal to the aggregate of 60% of the Lac Ste-Anne Claim and 60% of the outstanding amount under the CIBC Line of
Credit. 
  7.                      
HQP and Newco (using proceeds from the payment received pursuant to Section 2.4.1 of the Implementation Agreement) shall contribute to the Partnership, in proportion to their respective ownership interests in
the Partnership, such amounts as are necessary for the Partnership to repay in full the ACCC Loan, the Lac St-Anne Claim and the amounts owed under the CIBC Line of Credit.? 

  8.                        The Partnership shall repay in full the CIBC Line of Credit and the CIBC Line of Credit will be terminated. 
  9. 
                      ACCC will repay to Alcoa the Alcoa Reallocation amount. 
  
  
   *  Alcoa's new wholly-owned subsidiary which will hold a 40% interest in the Partnership.  

   ?   For US tax purposes, it may be preferable to have a certain delay for steps 6 and 7 after closing.
