-5-

Acquisition Corp. shall provide the Sellers with access to copies of all working papers and other relevant documents to prepare and verify the entries contained in the Final Statement.

	(b)		Unless the Sellers, within 30 calendar days following receipt of the Final Statement, delivers to Acquisition Corp. a written notice (the “Notice of Objection”) objecting to the Final Statement, the Final Statement shall be final and binding on the Parties.

	(c)		If, within 30 calendar days following receipt of the Final Statement, the Sellers deliver the Notice of Objection to Acquisition Corp., then the Sellers and Acquisition Corp. shall negotiate in good faith and attempt to resolve the matters in dispute (the “Disputed Matters”). If such negotiations resolve all of the Disputed Matters within 15 calendar days following delivery of the Notice of Objection to Acquisition Corp., then the Final Statement (after giving effect to any adjustments to be made in accordance with such resolution) shall be final and binding on the Parties.

	(d)		If the negotiations described in Section 2.5(c) fail to resolve all of the Disputed Matters within 15 calendar days following delivery of the Notice of Objection to Acquisition Corp., then the Sellers and Acquisition Corp. shall submit the unresolved portion of the Disputed Matters (the “Unresolved Matters”) to Ernst & Young LLP or such other nationally recognized accounting firm in Canada as may be approved by the Sellers and Acquisition Corp. (the “Independent Accounting Firm”) and the Independent Accounting Firm shall render its option as to Unresolved Matters. Based on such opinion, the Independent Accounting Firm will then send to the Sellers and Acquisition Corp., within 30 calendar days of submission of all facts applicable to the Unresolved Matters, the determination of the Independent Accounting Firm on the Unresolved Matters and any adjustments to be made to the Final Statement. Upon receipt of such determination by the Sellers and Acquisition Corp., the Final Statement (after giving effect to any adjustments to be made in accordance with such determination and, if applicable, any adjustments to be made in accordance with the negotiations described in Section 2.5(c)) shall be final and binding on the Parties.

	(e)		(i) If there is a Cash Consideration Surplus, the Sellers shall pay to Acquisition Corp., or one or more of its Affiliates as directed in writing by Acquisition Corp., the amount of the Cash Consideration Surplus and upon and subject to such payment, the Sellers and Acquisition Corp. shall join in written instructions to the Escrow Agent to disburse the Purchase Price Adjustment Fund and earnings thereon to Acquisition Corp., (ii) if there is a Cash Consideration Deficiency that equals or exceeds the Purchase Price Adjustment Fund, Acquisition Corp. shall pay or cause to be paid the amount of the Cash Consideration Deficiency that exceeds the Purchase Price Adjustment Fund, if any, to the Sellers jointly and the Sellers and Acquisition Corp. shall join in written instructions to the Escrow Agent to disburse the Purchase Price Adjustment Fund and earnings thereon to the Sellers, or (iii) if there is a Cash Consideration Deficiency that is less than the Purchase Price Adjustment Fund, the Sellers and Acquisition Corp. shall join in written instructions to the Escrow Agent to

-6-

disburse from the Purchase Price Adjustment Fund an amount equal to the Cash Consideration Deficiency to the Sellers jointly, to disburse the remainder of the Purchase Price Adjustment Fund to Acquisition Corp. and to disburse the earnings through such date on the Purchase Price Adjustment Fund to the Sellers jointly and Acquisition Corp. pro rata based on the amounts of the Purchase Price Adjustment Fund paid to Acquisition Corp. and the Sellers’ jointly. The amount payable by the Sellers or Acquisition Corp. pursuant to this Section 2.5(e) (the “Payment Amount”) shall be paid within 10 calendar days after the Final Statement becomes final and binding on the Parties pursuant to Sections 2.5(a), (c) or (d), as the case may be, and the disbursement from the Purchase Price Adjustment Fund shall be made on the date of payment of the Payment Amount or the next succeeding Business Day. Any amounts not paid by Acquisition Corp. or the Sellers when required pursuant to this Section 2.5(e) shall bear interest from the required date of payment to the date of actual payment at the publicly announced prime rate of Royal Bank of Canada in effect from time to time, plus 4%.

	(f)		Any adjustments to the Purchase Price made pursuant to this Section 2.5 shall be considered to be an adjustment to the NACGI Cash Consideration and shall be taken into account in the allocation of the Purchase Price pursuant to Exhibit 2.4 as set forth in the final and binding Final Statement.

	(g)		The fees, costs and expenses of the Independent Accounting Firm in connection with Section 2.5(d) shall be apportioned between the Sellers jointly on the one hand, and Acquisition Corp. on the other, in the manner determined by the Independent Accounting Firm based upon the inverse proportion of the Unresolved Matters resolved in favour of the Sellers and Acquisition Corp. (i.e. so that the prevailing party or parties bears a lesser amount of such fees, costs and expenses). Otherwise, the Sellers and Acquisition Corp. shall each pay their own costs in connection with this Section 2.5 including, without limitation, the fees and expenses of their respective legal counsel and accountants, if any.

	(h)		Except as otherwise set forth in Exhibit 2.5(a), the Closing Balance Sheet shall be prepared in a manner consistent with GAAP.

TRANSACTION FINANCING

3.1 Intended Financing Structure

The Parties acknowledge that the Buyers intend to finance the Transactions in part through an offering of senior unsecured notes (high yield securities) (the “High-Yield Financing”) and borrowings under senior secured credit facilities (“Senior Secured Financing”) pursuant to a letter (the “Financing Letter”) received from BNP Paribas and BNP Paribas Securities Corp. (BNP Paribas and BNP Paribas Securities Corp. being sometimes referred to herein individually or collectively as “Paribas”). The Financing Letter contains a financial commitment by BNP Paribas to provide the Senior Secured Financing and an engagement of BNP Paribas Securities Corp. to act as lead arranger for the High-Yield Financing. The Financing Letter also requires an initial equity investment in Holdco of C$92.5 million (the “Initial Equity Requirement”). BNP Paribas has also provided to the Buyers an alternative financing commitment (the “Alternative Financing Commitment”) providing for a bridge financing facility to Holdco (the “Bridge Facility”) to permit the Transactions to be completed by the Buyers.

3.2 Alternative Financing Commitment

If, at any time prior to the Termination Date, on the basis of advice received from Paribas, which advice shall be solicited by the Buyers from Paribas sufficiently in advance of the Termination Date to ensure that the steps set out in this Section 3.2 and the Closing of the Transactions in reliance on the Alternative Financing Commitment can be completed prior to the Termination Date, if necessary, the Buyers are of the reasonable opinion that the High-Yield Financing cannot be completed, then:

	(a)		not later than the first to occur of (i) two Business Days after receipt of such advice, or (ii) the Business Day immediately preceding the then scheduled Closing Date, the Buyers shall provide written notice of such opinion to the Sellers;

	(b)		within five Business Days after receipt of the notice referred to in clause (a), the Sellers may, in their sole discretion, provide written notice to the Buyers stating that the Sellers do not wish the Buyers to close under the Alternative Financing Commitment and that the Sellers are terminating the Transactions pursuant to Section 11.1(b);

	(c)		if the written notice to the Buyers under Section 3.2(b) is not given, the then scheduled Closing Date shall be rescheduled, if necessary, to the time and date at which such closing under the Alternative Financing Commitment is scheduled to occur (which shall be a date prior to the Termination Date), and the Parties shall complete the Transactions upon the terms and subject to the conditions set forth herein except that:

-11-

	(i)		the number of NACGI Cash Shares shall be the adjusted number specified in the definition of such term and the NACGI Cash Consideration shall be reduced by C$40 million; and

	(ii)		Norama shall sell, assign, transfer and convey to Newco, and Newco shall purchase from Norama, the Additional NACGI Exchange Shares and in consideration for the Additional NACGI Exchange Shares Newco shall issue to Norama the Newco Series B Share Consideration (and such shares shall form part of the Share Consideration for purposes of the definition contained in Section 2.4).

3.3 Refinancing

	(a)		If the Transactions are completed in reliance on the Alternative Financing Commitment, then Newco shall cause Holdco to use its reasonable commercial efforts to (i) refinance the Bridge Facility (the “Bridge Refinancing”) as quickly as possible after the Closing Date, and (ii) complete the Bridge Refinancing in an amount sufficient to fully repay the Bridge Facility and to enable Holdco to provide funds to Newco or Parent to fully redeem or purchase the Newco Series B Share Consideration. If the aggregate amount of the Bridge Refinancing, net of costs and expenses, exceeds the amount required to pay in full the Bridge Facility then outstanding (including principal, accrued interest, and any premiums or prepayment fees), then any excess amount shall be provided by Holdco to Newco or Parent and used by Newco or Parent first to pay accrued but unpaid dividends on the Newco Series B Share Consideration, and then to redeem or purchase the Newco Series B Share Consideration in an aggregate amount not to exceed the lesser of (A) C$40 million plus such accrued but unpaid dividends or (B) such excess amount.

	(b)		If any part of the Newco Series B Share Consideration is not to be redeemed or purchased pursuant to the Bridge Refinancing, then Newco shall use its reasonable commercial efforts to negotiate into the documents governing the Bridge Refinancing the ability to make cash dividend payments on the Newco Series B Share Consideration and, assuming the success of such negotiations, shall make cash dividend payments on the Newco Series B Share Consideration, as follows:

	(i)		for any fiscal year of Newco in which EBITDA is equal to or greater than C$75 million, Newco shall pay cash dividends equal to a minimum of 50% of the required dividends on the Newco Series B Share Consideration for such fiscal year; and

	(ii)		for any fiscal year of Newco in which EBITDA is equal to or greater than C$85 million, Newco shall pay cash dividends equal to 100% of

-12-

the required dividends on the Newco Series B Share Consideration for such fiscal year.

Failure to provide such notice shall not affect the right of the Indemnitee to indemnification except to the extent such failure shall have resulted in liability to the Indemnitor that could have been actually avoided had such notice been provided within such required time period.

-63-

	(b)		Except as provided in Sections 9.3(c) with respect to Proceedings involving Post-Closing Contract Payment Liabilities, the obligations and liabilities of an Indemnitor under this Article 9 with respect to Losses arising from claims of any third party (including any Governmental Entity) that are subject to the indemnification provided for in this Article 9 (“Third Party Claims”) shall be governed by the following additional terms and conditions. If an Indemnitee shall receive notice of any Third Party Claim, then the Indemnitee shall give the Indemnitor prompt notice of such Third Party Claim and, except as otherwise provided in Section 9.3(c), the Indemnitor may, at its option, assume and control the defense of such Third Party Claim at the Indemnitor’s expense and through counsel of the Indemnitor’s choice reasonably acceptable to the Indemnitee. In the event the Indemnitor assumes the defense against any such Third Party Claim as provided above, the Indemnitee shall have the right to participate at its own expense in the defense of such Third Party Claim, shall cooperate with the Indemnitor in such defense and will make available on a reasonable basis to the Indemnitor all witnesses, pertinent records, materials and information in its possession or under its control relating thereto as is reasonably required by the Indemnitor and at the Indemnitor’s expense. In the event the Indemnitor does not elect to conduct the defense against any such Third Party Claim, the Indemnitor shall pay all reasonable costs and expenses of such defense as incurred, shall cooperate with the Indemnitee (and be entitled to participate) in such defense and make available to the Indemnitee on a reasonable basis all such witnesses, records, materials and information in its possession or under its control relating thereto as is reasonably required by the Indemnitee, and shall execute or cause to be executed such action as reasonably requested by the Indemnitee to enable the Indemnitee to take any action the Indemnitee deems appropriate with respect to any such defense. Except for the settlement of a Third Party Claim to which Section 9.3(c) does not apply that involves the payment of money only and is paid in full by the Indemnitor and there is no finding or admission of wrongdoing or violation of law by the Indemnitee and no adverse effect on any other claims that may be made against the Indemnitee or any rights or claims held by the Indemnitee, no Third Party Claim may be settled without the written consent of the Indemnitee, such consent not to be unreasonably withheld or delayed. Without restricting the generality of the foregoing, neither the Principals nor any Seller may, without the written consent of Acquisition Corp. (not to be unreasonably withheld), settle or compromise Taxes or Tax issues related to any matter which may affect Tax liabilities of the Buyers or the NACGI Companies.

	(c)		Notwithstanding Section 9.3(b), Acquisition Corp. as Indemnitee shall have the sole right to assume the defense of and control any Third Party Claim involving any Proceeding with respect to any Post-Closing Contract Payment Liability. In the event Acquisition Corp. assumes the defense of any such Third Party Claim, the Indemnitor shall have the right to participate at its own expense in the defense of such Third Party Claim and shall

-64-

			cooperate with Acquisition Corp. in such defense and will make available on a reasonable basis to Acquisition Corp. all witnesses, pertinent records, materials and information in its possession or under its control relating thereto as is reasonably required by Acquisition Corp. In the event Acquisition Corp. assumes the defense of any such Third Party Claim, Acquisition Corp. and the Sellers shall execute or cause to be executed such documents and shall take such action as reasonably requested by Acquisition Corp. to enable Acquisition Corp. to take any action Acquisition Corp. deems appropriate, acting reasonably, with respect to any such Proceedings. If Acquisition Corp. does not elect to conduct the defense against any such Third Party Claim, Acquisition Corp. shall cooperate with the Indemnitor (and be entitled to participate) in such defense and make available to the Indemnitor on a reasonable basis all such witnesses, records, materials and information in its possession or under its control relating thereto as is reasonably required by the Indemnitor and at the Indemnitor’s expense. Neither the Indemnitor nor the Indemnitee may, without the written consent of the other, such consent not to be unreasonably withheld or delayed, settle any Third Party Claim covered by this Section 9.3(c).

	(d)		With respect to any Tax Return of NAEL, NAEL shall keep Acquisition Corp. duly informed of any Proceedings in connection with any matter which may affect the Taxes payable by Acquisition Corp., any of the NACGI Companies or any of their Affiliates, and shall promptly provide Acquisition Corp. with copies of all correspondence and documents relates to such Proceedings.

	(e)		In the event any Indemnitee should have a claim against any Indemnitor hereunder that does not involve a Third Party Claim, the Indemnitee shall deliver to the Indemnitor a written notice (the “Indemnity Notice”) describing in reasonable detail the nature of the claim, an estimate of the amount of Damages attributable to such claim to the extent feasible (which estimate shall not be conclusive of the final amount of such claim) and the basis of the Indemnitee’s request for indemnification under this Agreement. If the Indemnitor does not notify the Indemnitee within 20 days from its receipt of the Indemnity Notice that the Indemnitor accepts such claim, the claim specified by the Indemnitee in the Indemnity Notice shall be deemed denied by the Indemnitor.

	(e)		Except in cases of intentional misstatement or omission, there shall be no indemnification by the Buyers for Damages under Section 9.2 until such Damages exceed C$100,000 in the aggregate (the “Buyers’ Basket Amount”) and, once all of such Damages exceeds the Buyers’ Basket Amount, the Buyers shall be obligated to the Seller Indemnified Parties for only that portion of all such Damages that is in excess of the Buyers’ Basket Amount.

9.6 Payment

Payment of any amounts due pursuant to this Article 9 shall be made within 10 Business Days after notice is sent by the Indemnitee to the Indemnitor.

If and to the extent the Indemnitee shall make written demand upon the Indemnitor for indemnification pursuant to this Article 9 and the Indemnitor shall refuse or fail to pay in full within 10 Business Days of such written demand the amounts demanded and due pursuant hereto and in accordance herewith, then the Indemnitee may utilize any legal or equitable remedy to collect from the Indemnitor the amount of its Losses. Nothing contained herein is intended to limit or constrain the Indemnitee ‘s rights against the Indemnitor for indemnity, the remedies herein being cumulative and in addition to all other rights and remedies of the Indemnitee.

If a Person has a right to indemnification with respect to Damages arising as a result of or arising out of or by virtue of more than one clause in Section 9.1 or Section 9.2, such Person may elect to pursue indemnification under any one or more of such clauses. For purposes of this Article 9, Damages for which any Indemnitee is entitled to indemnification shall be reduced by the amount of any insurance proceeds actually received by such Indemnitee with respect to such Damages, net of any copayment and retrospective premium adjustment to the extent resulting from such Damages and increased premiums resulting from such Damages; but the possibility of the receipt of any such insurance proceeds shall not delay or reduce any Indemnitor’s obligations to pay in full all of such Indemnitor’s indemnification obligations under this Article 9 when due. An Indemnitee shall not be required to pay any Damages prior to making a claim for indemnification therefor under this Article 9 or prior to the receipt of indemnification payment therefor from any Indemnitor.
