2.1.1.7 the by-laws of Amalco shall be the by-laws of Target in effect prior to the Effective Time;

In addition, if required, the exercise price of each Replacement Option will be increased such that the excess, if any, of the aggregate fair market value of the

-15-

Purchaser Shares subject to such Replacement Option immediately after the Effective Time over the aggregate exercise price under the Replacement Option equals the excess, if any, of the aggregate fair market value of the Target Shares subject to the Target Stock Option Plan immediately before the Effective Time over the aggregate exercise price under such Target Stock Option Plan.

ADDITIONAL AGREEMENTS

7.1 Notice and Cure Provisions

7.1.1 Each Party will give prompt notice to the other of the occurrence, or failure to occur, at any time from the date hereof until the earlier to occur of the termination of this Agreement and the Effective Time of any event or state of facts which occurrence or failure would, or would be likely to:

-50-

7.1.1.1 cause any of the representations or warranties of either Party contained herein to be untrue or inaccurate in any material respect on the date hereof or at the Effective Time; or

7.1.1.2 result in the failure to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by either Party hereunder prior to the Effective Time.

7.1.2 No Party may elect not to complete the transactions contemplated hereby pursuant to the conditions set forth herein or any termination right arising therefrom and no payments are payable as a result of such election pursuant to Section 0 unless forthwith and in any event prior to the Effective Time, the Party intending to rely thereon has delivered a written notice to the other Party specifying in reasonable detail all breaches of covenants, representations and warranties or other matters which the Party delivering such notice is asserting as the basis for the non-fulfillment or the applicable condition or termination right, as the case may be. If any such notice is delivered, provided that a Party is proceeding diligently to cure such matter and such matter is capable of being cured, no Party may terminate this Agreement until the expiration of a period of 15 business days from such notice, and unless such matter has not been cured by such date. If such notice has been delivered prior to the date of the Target Meeting, such meeting shall, unless the Parties agree otherwise, be postponed or adjourned until the expiry of such period. If such notice has been delivered prior to the filing of the Articles of Arrangement with the Enterprise Registrar, such filing shall be postponed until two business days after the expiry of such period.

-51-

enter into any agreement, understanding, arrangement or Contract in respect of an Acquisition Proposal (other than a confidentiality agreement permitted by paragraph 0); provided, however, that prior to the date the Required Vote is obtained, nothing contained in this Agreement shall prevent (subject to compliance with the other provisions of this 0) the Board of Directors of Target from (i) engaging in discussions or negotiations or furnishing information (ii) making a Change in Target Recommendation (iii) approving, endorsing or recommending or proposing publicly to approve, endorse or recommend an Acquisition Proposal or (iv) entering into an agreement in connection with an unsolicited, written Acquisition Proposal:

7.2.1.1 that did not result from a breach of this Section 0; and

7.2.1.2 in respect of which the Board of Directors of Target determines in good faith after consultation with the Financial Advisor and Target’s outside counsel that the Acquisition Proposal would be reasonably likely to lead to a Superior Proposal;

“Superior Proposal” shall mean any unsolicited written Acquisition Proposal which the Board of Directors of Target determines, in its good faith judgment, after receiving the advice of Financial Advisors and after taking into account all the terms and conditions of the Acquisition Proposal, is on terms and conditions more favourable to the Target Shareholders than those contemplated by this Agreement (including any alterations to this Agreement agreed to in writing by Purchaser in response thereto in accordance with Section 0).

7.2.2 Target shall, and shall cause the officers, directors, employees, representatives and agents of Target and its subsidiaries to, immediately terminate any existing solicitations, discussions or negotiations with any person (other than Purchaser) that has made, indicated any interest to make an Acquisition Proposal. Target shall promptly request the return or destruction of all information provided to any third party which, at any time since January 1, 2005, has entered into a confidentiality agreement with Target relating to a potential Acquisition Proposal to the extent that such information has not previously been returned or destroyed, and shall use all commercially reasonable efforts to ensure that such requests are honoured in accordance with the terms of such agreement.

7.2.3 Target shall promptly notify Purchaser, at first orally and thereafter in writing, of any Acquisition Proposal or inquiry received after the date hereof (whether or not relating to any Acquisition Proposal or inquiry received prior to the date hereof) that could reasonably be expected to lead to an Acquisition Proposal, in each case received after the date hereof, of which any of its directors or, officers are or become aware, or any amendments to the foregoing, or any request for non-public information relating to Target or any of its subsidiaries in connection with an Acquisition Proposal or for access to the properties, books or records of Target or any of its subsidiaries by any person that informs Target or such subsidiary that it is considering making, or

-52-

has made, an Acquisition Proposal and any amendment thereto and a description of the material terms and conditions of any such Acquisition Proposal or inquiry. Target shall keep Purchaser informed of any change to the material terms of any such Acquisition Proposal or inquiry.

7.2.4 If Target receives a request for material non-public information from a person who proposes an unsolicited Acquisition Proposal where Target is not in breach of paragraph 0 and the Board of Directors of Target determines in good faith after consultation with Financial Advisors and its outside counsel that such proposal would be reasonably likely to lead to a Superior Proposal, then, and only in such case, the Board of Directors of Target may, subject to the execution by such person of a confidentiality agreement having terms not less favourable to Target than the Confidentiality Agreement, provide such person with access in accordance with paragraph 0 to information regarding Target, provided that Purchaser is promptly provided with a list and copies of all information provided to such person not previously provided to Purchaser and is promptly provided with access to information similar to that which was provided to such person.

7.2.5 Nothing contained in this Section 0 shall prohibit the Board of Directors of Target from making any disclosure to Target’s Shareholders prior to the Effective Time if, in the good faith judgment of the Board of Directors of Target, after consultation with outside counsel, such disclosure is necessary for the Board of Directors to act in a manner consistent with its fiduciary duties or is otherwise required under applicable Law, including its obligations under Rule 14e-2 under the Exchange Act or from responding through a director’s circular or otherwise as required by applicable Securities Laws to an Acquisition Proposal or from calling and holding a meeting of the Target Shareholders requisitioned by such shareholders pursuant to the QCA or ordered to be held by a court under the QCA.

7.3 Right to Match

7.3.1 Subject to paragraph 0, Target covenants that it will not accept, approve, recommend or enter into any agreement, understanding, arrangement or Contract in respect of a Superior Proposal (other than a confidentiality agreement permitted by paragraph 0) unless:

7.3.1.1 Target has complied with its obligations under Section 0 and the other provisions of this 0 and has provided Purchaser with a copy of the Superior Proposal; and

7.3.1.2 a period (the “Response Period”) of three business days shall have elapsed from the date on which Purchaser received written notice from the Board of Directors of Target that the Board of Directors of Target determined, subject only to compliance with this Section 0, to accept, approve, recommend or enter into a binding

-53-

agreement to proceed with the Superior Proposal. In the event that Target provides Purchaser with the notice contemplated in this Section on a date that is less than three business days prior to the Target Meeting, Target shall be entitled to adjourn the Target Meeting to a date that is not more than three business days after the date of such notice.

7.3.2 During the Response Period, Purchaser will have the right, but not the obligation, to offer to amend the terms of this Agreement. The Board of Directors of Target will review any such proposal by Purchaser to amend the terms of this Agreement, including an increase in, or modification of, the consideration to be received by the holders of Target Shares, to determine whether the Acquisition Proposal to which Purchaser is responding would be a Superior Proposal when assessed against the Arrangement as it is proposed by Purchaser to be amended. If the Board of Directors of Target determines that the Acquisition Proposal would no longer be a Superior Proposal if the Arrangement was so amended and Purchaser enters into an amendment to this Agreement incorporating the terms of the amended offer, the Board of Directors of Target will promptly publicly reaffirm its recommendation of the Arrangement. If the Board of Directors of Target determines that the Acquisition Proposal remains a Superior Proposal, Target may approve, recommend, accept or enter into an agreement, understanding or arrangement to proceed with the Superior Proposal.

7.3.3 Each successive amendment to any Acquisition Proposal that results in an increase in, or modification of, the consideration (or value of such consideration) to be received by the holders of Target Shares shall constitute a new Acquisition Proposal for the purposes of this Section 0 and Purchaser shall be afforded a new Response Period in respect of each such Acquisition Proposal.

7.4 Agreement as to Termination Fee

7.4.1 Notwithstanding any other provision relating to the payment of fees or expenses, including the payment of brokerage fees, Target shall pay, or cause to be paid, to Purchaser by wire transfer of immediately available funds an amount equal to $45 million (the “Termination Fee”) less any amounts actually paid by Target to Purchaser pursuant to Section 0, if any of the following events occurs:

7.4.1.1 if Purchaser shall have terminated this Agreement pursuant to subparagraph 0, in which case payment shall be made within two business days of such termination;

7.4.1.2 if Target shall have terminated this Agreement pursuant to subparagraph 0, in which case payment shall be made before

-54-

or concurrently with such termination and shall be a condition to the effectiveness of such termination;

7.4.1.3 if (A) after the date hereof and before the Target Meeting, an Acquisition Proposal shall have been made or proposed to Target or otherwise publicly announced, or a person has publicly announced an intention to do so (which has not been withdrawn) and (B) this Agreement is terminated by either Purchaser or Target pursuant to subparagraph 0 or subparagraph 0 or by Purchaser pursuant to subparagraph 0 and (C) during the period commencing on the date hereof and ending six months following the termination of this Agreement (x) an Acquisition Proposal is consummated, or (y) the Board of Directors approves or recommends an Acquisition Proposal, or the Target enters into a definitive agreement with respect to an Acquisition Proposal, and that Acquisition Proposal is subsequently consummated at any time thereafter (whether or not during the aforementioned period ending six months following the termination of this Agreement), in which case payment shall be made within two business days of the date on which Target consummates such Acquisition Proposal.

7.4.2 In no event shall Target be required to pay under paragraph 0, in the aggregate, an amount in excess of the Termination Fee.

7.4.3 Subject to subparagraph 0 and notwithstanding Section 0, Target shall pay, or cause to be paid, to Purchaser by wire transfer of immediately available funds, the reasonable documented expenses of Purchaser and its affiliates incurred in connection with the transactions contemplated hereby not to exceed $2 million if Purchaser shall have terminated this Agreement pursuant to subparagraph 0. Such payment is made subject to any other Purchaser’s rights in case of a wilful breach by Target of its covenants hereunder.

7.4.4 Notwithstanding Section 0, Purchaser shall pay, or cause to be paid, to Target by wire transfer of immediately available funds, the reasonable documented expenses of Target and its affiliates incurred in connection with the transactions contemplated hereby not to exceed $2 million if Target shall have terminated this Agreement pursuant to subparagraph 0. Such payment is made subject to any other Target’s rights in case of a wilful breach by Purchaser of its covenants hereunder.

7.7.2 Purchaser agrees that it shall directly honour all rights to indemnification or exculpation now existing in favour of present and former officers and directors of Target and its subsidiaries, which shall survive the completion of the Arrangement and shall continue in full force and effect for a period of not less than six years from the Effective Time.

7.7.3 The provisions of this Section 0 are intended for the benefit of, and shall be enforceable by, each insured or indemnified person, his or her heirs and his or her legal representatives and, for such purpose, Target hereby confirms that it is acting as agent and trustee on their behalf.

Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Panics as closely as possible in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the fullest extent possible.

9.8 Rules of Construction

The Parties to this Agreement have been represented by counsel during the negotiation and execution of this Agreement and waive the application of any Laws or rule of construction providing that ambiguities in any agreement or other document shall be construed against the Party drafting such agreement or other document.

9.9 Counterparts, Execution

This Agreement may be executed in two or more counterparts, each of which shall be deemed to be an original but all of which together shall constitute one and the same instrument.
