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.

10.                     HQ will pay BCFPI for the electricity purchased from BCFPI's Gatineau Mill. ACCC, BCFPI or one of the Petitioners (as defined in the order issued by the Superior Court of the Province of Quebec on April 17, 2009 pursuant to the Companies' Creditors Arrangement Act in respect of, inter alia, ACI and its subsidiaries) will repay to HQ the amount estimated by HQ of $31,246,500 (being all amounts owed by ACCC, BCFPI and their respective affiliates to HQ for electricity purchased from HQ, including the remaining amount estimated by HQ of approximately $8,500,000 owed by BCFPI and pre-petition amounts).

Post-closing, the following step will occur:

11.                     The Partnership shall repay in full the ACCC Loan to ACI and the Lac Ste-Anne Claim to HQ.
