RECITAL:

A.		On 7 October 2009 the EMEA Sellers, the Joint Administrators, the Joint Israeli Administrators and the Purchaser entered into an Asset Sale Agreement (the “Agreement") whereby the EMEA Sellers agreed to sell and transfer to the Purchaser the EMEA Assets (as defined in the Agreement) for the consideration and upon the terms and subject to the conditions set out in the Agreement. On the same date the Sellers and the Purchaser entered into the North American Agreement whereby the Sellers agreed to sell and transfer to the Purchaser the Assets (as defined in the North American Agreement) for the consideration and upon the terms and subject to the conditions set out in the North American Agreement.
B.		On 15 October 2009 hearings were held in the US Bankruptcy Court and the Canadian Court to approve, amongst other things, the Sellers’ entry into the North American Agreement and the Bidding Procedures and Bid Protections.
C.		On 16 October 2009, each of the US Bankruptcy Court and the Canadian Court entered orders approving the North American Agreement and the Bidding Procedures and Bid Protections, subject to certain amendments, as set out in those orders (the “Court Orders”).
D.		Pursuant to the Court Orders, consistent amendments are to be made to the Agreement. Accordingly, the parties agree that the Agreement shall be amended on the terms set out in this Deed.

IT IS AGREED as follows:

1.		INTERPRETATION
1.1		Unless the context otherwise requires or unless otherwise defined in this Deed words and phrases defined in the Agreement (as amended by this Deed) shall have the same meanings where used in this Deed.

2

Deed of Amendment

1.2		References in the Agreement to “this Agreement” shall, with effect from and including the date of this Deed and unless the context dictates otherwise, be a reference to the Agreement as amended by this Deed and words such as “herein”, “hereof”, “hereby” and “hereto” where they appear in the Agreement shall be construed accordingly.
2.		AMENDMENTS TO THE AGREEMENT
2.1		The first sentence of clause 15.5 of the Agreement shall be deleted and replaced (without prejudice to the remainder of Clause 15.5 of the EMEA ASA) with the following:
		“In the event that (i) this Agreement is terminated by the Purchaser pursuant to Clause 15.4.4 or Clause 15.4.5; or (ii) the North American Agreement is terminated by either Primary Party pursuant to Section 10.1(b)(v) of the North American Agreement or by the Purchaser pursuant to Section 10.1(b)(ii), Section 10.1(c) or Section 10.1(d) of the North American Agreement or by the Main Sellers pursuant to Section 10.1(b)(iii), Section 10.1(b)(iv), Section 10.1(b)(viii) or Section 10.1(e) of the North American Agreement, then the EMEA Sellers shall pay to the Purchaser in immediately available funds, (A) within two (2) Business Days following such termination (other than with respect to any termination pursuant to Section 10.1(b)(v) of the North American Agreement), or (B) within two (2) Business Days following the consummation of an Alternative Transaction that is consummated at any time on or prior to the date that is twelve (12) months following any termination of the North American Agreement pursuant to Section 10.1(b)(v) of the North American Agreement, a cash fee equal to five million, three hundred and forty-eight thousand U.S. dollars (U.S.$5,348,000) (the “EMEA Break-Up Fee”).”
2.2		A new definition shall be inserted in Schedule 1 of the EMEA ASA as follows:
		““North American Agreement Amendment” means Amendment No. 1 to the Asset Sale Agreement between the Main Sellers and the Purchaser.”
2.3		In Clause 10.9 of the EMEA ASA, every reference to “Section 5.5(a) of the North American Agreement” and “Section 5.5(a)(iii) of the North American Agreement” shall be followed by the words: “(as amended by the North American Agreement Amendment”)”
2.4		Subject to the terms of, and except as amended by this Deed, the Agreement shall remain in full force and effect between the parties.
3.		EXCLUSION OF LIABILITY AND ACKNOWLEDGEMENT
3.1		Subject to Clause 3.4.2, notwithstanding that this Deed shall have been signed by the Joint Administrators and the Joint Israeli Administrators both in their capacities as administrators of the EMEA Debtors for and on behalf of the EMEA Debtors and of the Israeli Company for and on behalf of the Israeli Company respectively and in their personal capacities, it is hereby expressly agreed and declared that no personal Liability under or in connection with this Deed shall fall on the Joint Administrators, the Joint Israeli Administrators or their respective firm, partners, employees, agents, advisers or representatives whether such personal Liability would arise under paragraph 99(4) of schedule B1 to the Insolvency Act, or otherwise howsoever. For the avoidance of doubt, this Clause 3.1 shall not operate to prevent any claim of the Purchaser against the EMEA Debtors under this Deed or the Agreement being an expense of the administration as described in Paragraph 99(4) of Schedule B1 and Rule 2.67 of the Insolvency Act or against the Israeli Company under this Agreement being “expenses of the stay of proceedings”.

3.3		For the avoidance of doubt, (but without prejudice to the other terms of this Deed) the parties hereby agree that the terms of Clauses 3.1 and 3.2 do not, in and of themselves, provide that the Purchaser is under any obligation to indemnify, nor become liable or responsible for, any actions, proceedings, claims, demands, costs, expenses, damages, compensation, fines, penalties or other Liabilities against the Joint Administrators, the Joint Israeli Administrators or the Non-Debtor Seller Directors by any Person.
3.4		The Joint Administrators and the Joint Israeli Administrators are party to this Deed in their personal capacities only for the purpose of receiving the benefit of this Clause 3 and the exclusions, limitations, undertakings, covenants and indemnities in their favour contained in this Deed.

3.5		Subject to Clause 3.4.2, the Purchaser further acknowledges the following:

	3.5.1		it has entered into this Deed without reliance on any warranties or representations made by the EMEA Sellers or by any of their employees, agents or representatives, or by the Joint Administrators, the Joint Israeli Administrators or any of their respective firms, partners, employees, agents, advisors or representatives and (save in respect of fraud, fraudulent misrepresentation or fraudulent misstatement) it shall not have any remedy in respect of any misrepresentation or untrue statement by such persons made by or on behalf of any other party to this Deed; and
	3.5.2		nothing in this Clause 3 or any other provision of this Deed shall prevent any party from bringing any action against any other party, whether in a personal or any other capacity, for fraud, fraudulent misrepresentation or fraudulent misstatement.

Subject to the foregoing, this Deed shall inure to the benefit of and be binding upon the parties hereto and their respective successors and permitted assigns.
4.3		In the event that any provision of this Deed shall be void or unenforceable by reason of any provision of applicable Law, it shall be deleted and the remaining provisions hereof shall continue in full force and effect and if necessary, be so amended as shall be necessary to give effect to the spirit of this Deed so far as possible (unless such invalidity or unenforceability materially impairs the ability of the parties hereto to consummate the transactions contemplated by this Deed).

4

Deed of Amendment

4.4		The provision for services of notices set out in Clause 17 (Notices and Receipts) of the Agreement shall also apply for the purposes of this Deed.
4.5		This Deed may be executed in any number of counterparts and by the parties to it on separate counterparts, each of which when executed and delivered shall be an original but all the counterparts together constitute one instrument.
4.6		Without prejudice to Clause 3 (Exclusion of Liability and Acknowledgement) of this Deed to the extent that the benefit of any provision in this Deed is expressed to be conferred upon:

	4.6.1		the Joint Administrators or the Joint Israeli Administrators, where necessary to give effect to any such provision the EMEA Debtors or the Israeli Company (as the case may be) shall hold such benefit as trustees for each Joint Administrators, or the Joint Israeli Administrators; and

4.8		No failure to exercise nor any delay in exercising, on the part of any party, any right or remedy under this Deed shall operate as a waiver thereof, nor shall any single or partial exercise of any right or remedy prevent any further or other exercise thereof or the exercise of any other right or remedy. The rights and remedies provided in this Deed are cumulative and not exclusive of any rights or remedies provided by Law.
4.9		No party shall be deemed to have waived any provision of this Deed unless such waiver is in writing, and then such waiver shall be limited to the circumstances set forth in such written waiver.
