2.2 Grant of the Exchange Right. Neutron Holdings hereby grants to 2024069 the right (hereinafter the ''Exchange Right''), upon the occurrence and during the continuance of an Insolvency Event, to require Neutron Holdings to purchase from it all or any part of the Exchangeable Shares it holds, all in accordance with the provisions of this Agreement. Neutron Holdings hereby acknowledges receipt from 2024069 of good and valuable consideration (and the adequacy hereof) for the grant of the Exchange Right and the Automatic Exchange Rights described in subsection 2.7 hereof by Neutron Holdings to 2024069.

The purchase price payable by Neutron Holdings for each Exchangeable Share to be purchased under the Exchange Right shall be an amount per share equal to (a) the Current Market Value of a Parent Common Share determined on the last Business Day prior to the day of closing of the purchase and sale of such Exchangeable Share under the Exchange Right, which shall be satisfied in full by Neutron Holdings causing to be delivered to 2024069 one Parent Common Share, plus (b) to the extent not paid by Neutron Exchangeco on the designated payment date therefor, an additional amount equal to and in satisfaction of the full amount of all declared and unpaid dividends on each such Exchangeable Share held by 2024069 on any dividend record date which occurred prior to the closing of the purchase and sale.

Upon payment by Neutron Holdings of such purchase price, 2024069 shall cease to have any right to be paid any amount in respect of declared and unpaid dividends on each such Exchangeable Share by Neutron Exchangeco.

2.4 Delivery of Parent Common Shares. Promptly after the receipt of the certificates representing the Exchangeable Shares which 2024069 desires Neutron Holdings to purchase under the Exchange Right, duly endorsed for transfer to Neutron Holdings, Neutron Holdings shall promptly thereafter deliver or cause to be delivered to 2024069 the number of Parent Common Shares issuable in connection with the exercise of the Exchange Right, and on the applicable payment date cheques for the balance, if any, of the total purchase price therefor without interest (but less any amounts withheld pursuant to subsection 2.8). Immediately upon the giving of notice by 2024069 to Neutron Holdings of the exercise of the Exchange Right, the closing of the transaction of purchase and sale contemplated by the Exchange Right shall be deemed to have occurred and the holder of such Exchangeable Shares shall be deemed to have transferred to Neutron Holdings all of such holder's right, title and interest in and to such Exchangeable Shares and shall cease to be a holder of such Exchangeable Shares and shall not be entitled to exercise any of the rights of a holder in respect thereof, other than the right to receive its proportionate part of the total purchase price therefor, unless the requisite number of Parent Common Shares is not delivered by Neutron Holdings to 2024069 within five Business Days of the date of the giving of such notice or the balance of the purchase price, if any, is not paid by Neutron Holdings on the applicable payment date therefor, in which case the rights of 2024069 shall remain unaffected until such Parent Common Shares are so delivered, and the balance of the purchase price, if any, has been paid, by Neutron Holdings.

2.5 Exercise of Exchange Right Subsequent to Retraction. In the event that 2024069 has exercised its right under subsection III.5 of the Share Provisions to require Neutron Exchangeco to redeem any or all of the Exchangeable Shares (the ''Retracted Shares'') and is notified by Neutron Exchangeco pursuant to paragraph III.5(g) of the Share Provisions that Neutron Exchangeco will not be permitted as a result of solvency requirements of applicable law to redeem all such Retracted Shares, and provided that Neutron Holdings shall not have exercised the Retraction Call Right with respect to the Retracted Shares and that 2024069 has not revoked the retraction request pursuant to paragraph III.5(d) of the Share Provisions, the retraction request will constitute and will be deemed to constitute notice from 2024069 to Neutron Holdings of exercise of the Exchange Right with respect to those Retracted Shares that Neutron Exchangeco is unable to redeem.

2.6 Notice of Insolvency Event. As soon as practicable following the occurrence of an Insolvency Event or any event that with the giving of notice or the passage of time or both would be an Insolvency Event, Neutron Exchangeco shall give written notice thereof to 2024069.

2.7 Automatic Exchange on Liquidation of Neutron

	(a)	Neutron will give 2024069 written notice of each of the following events at the time set forth below:
		(i)	in the event of any determination by the Board of Directors of Neutron to institute voluntary liquidation, dissolution or winding-up proceedings with respect to Neutron or to effect any other distribution of assets of Neutron among its shareholders for the purpose of winding up its affairs, at least 60 days prior to the proposed effective date of such liquidation, dissolution, winding-up or other distribution; and

-5-

		(ii)	as soon as practicable following the earlier of (A) receipt by Neutron of notice of, and (B) Neutron otherwise becoming aware of, any threatened or instituted claim, suit, petition or other proceedings with respect to the involuntary liquidation, dissolution or winding-up of Neutron or to effect any other distribution of assets of Neutron among its shareholders for the purpose of winding up its affairs, in each case where Neutron has failed to contest in good faith any such proceeding commenced in respect of Neutron within 30 days of becoming aware thereof.
			Any event contemplated in (i) or (ii) above shall be referred to as a "Liquidation Event".
	(b)	In order that 2024069 will be able to participate on a pro rata basis with the holders of Parent Common Shares in the distribution of assets of Neutron in connection with a Liquidation Event, on the fifth Business Day prior to the effective date (the ''Liquidation Event Effective Date'') of a Liquidation Event all of the then outstanding Exchangeable Shares shall be automatically exchanged for Parent Common Shares ("Automatic Exchange Right"). To effect such automatic exchange, Neutron Holdings shall purchase on the fifth Business Day prior to the Liquidation Event Effective Date each Exchangeable Share then outstanding and held by 2024069, and 2024069 shall sell the Exchangeable Shares held by it at such time, for a purchase price per share equal to (a) the Current Market Value of a Parent Common Share determined on the fifth Business Day prior to the Liquidation Event Effective Date, which shall be satisfied in full by Neutron Holdings delivering to 2024069 one Parent Common Share, and (b) to the extent not paid by Neutron Exchangeco, an additional amount equal to and in satisfaction of the full amount of all declared and unpaid dividends on each such Exchangeable Share held by such holder on any dividend record date which occurred prior to the date of the exchange.
	(c)	On the fifth Business Day prior to the Liquidation Event Effective Date, the closing of the transaction of purchase and sale contemplated by the automatic exchange of Exchangeable Shares for Parent Common Shares shall be deemed to have occurred, and 2024069 shall be deemed to have transferred to Neutron Holdings all of the its right, title and interest in and to 2024069's Exchangeable Shares, any right of 2024069 to receive declared and unpaid dividends from Neutron Exchangeco shall be deemed to be satisfied and discharged and 2024069 shall cease to be a holder of such Exchangeable Shares and Neutron Holdings shall deliver to 2024069 the Parent Common Shares issuable upon the automatic exchange of Exchangeable Shares for Parent Common Shares and on the applicable payment date shall deliver to 2024069 a cheque for the balance, if any, of

-6-

the total purchase price for such Exchangeable Shares without interest but less any amounts withheld pursuant to subsection 2.8. Concurrently with 2024069 ceasing to be a holder of Exchangeable Shares, 2024069 shall be considered and deemed for all purposes to be the holder of the Parent Common Shares delivered pursuant to the automatic exchange of Exchangeable Shares for Parent Common Shares and the certificates held by 2024069 previously representing the Exchangeable Shares exchanged by 2024069 with Neutron Holdings pursuant to such automatic exchange shall thereafter be deemed to represent Parent Common Shares delivered to 2024069 by Neutron Holdings pursuant to such automatic exchange. Upon the request of 2024069 and the surrender of Exchangeable Share certificates duly endorsed in blank and accompanied by such instruments of transfer as Neutron Holdings may reasonably require, Neutron Holdings shall deliver or cause to be delivered to 2024069 certificates representing Parent Common Shares of which 2024069 is the holder.

2.8 Withholding Rights. Neutron, Neutron Holdings and Neutron Exchangeco shall be entitled to deduct and withhold from any consideration otherwise payable under this Agreement to any holder of Exchangeable Shares or Parent Common Shares such amounts as Neutron, Neutron Holdings or Neutron Exchangeco is required to deduct and withhold with respect to such payment under the Income Tax Act (Canada), the United States Internal Revenue Code of 1986 or any provision of provincial, state, local or foreign tax law, in each case as amended or succeeded. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes as having been paid to the holder of the shares in respect of which such deduction and withholding was made, provided that such withheld amounts are actually remitted to the appropriate taxing authority. To the extent that the amount so required to be deducted or withheld from any payment to a holder exceeds the cash portion of the consideration otherwise payable to the holder, Neutron, Neutron Holdings and Neutron Exchangeco are hereby authorized to sell or otherwise dispose of such portion of the consideration as is necessary to provide sufficient funds to Neutron, Neutron Holdings or Neutron Exchangeco, as the case may be, to enable it to comply with such deduction or withholding requirement and Neutron, Neutron Holdings and Neutron Exchangeco, as the context dictates, shall notify the holder thereof and remit to such holder any unapplied balance of the net proceeds of such sale.
