Notice of Acquisition Proposals

If the Company or any of its Subsidiaries or any of their respective Representatives receives or otherwise becomes aware of (X) any inquiry, proposal or offer that constitutes or may reasonably be expected to constitute or lead to an Acquisition Proposal, or (Y) any request for copies of, access to, or disclosure of, confidential information relating to the Company or any of its Subsidiaries in connection with any inquiry, proposal or offer that constitutes or may reasonably be expected to constitute or lead to an Acquisition Proposal, including but not limited to information, access, or disclosure relating to the properties, facilities, books or records of the Company or any of its Subsidiaries, the Company: (a) may, in a form reasonably acceptable to the Purchaser (i) communicate with any Person solely for the purposes of clarifying the terms of any such inquiry, proposal or offer made by such Person, (ii) advise any Person of the restrictions of the Arrangement Agreement, and (iii) advise any Person making such inquiry, proposal or offer that the Company Board has determined that such inquiry, proposal or offer does not constitute, or is not reasonably expected to constitute or lead to, a Superior Proposal; (b) shall promptly notify the Purchaser, at first orally, and then as soon as practicable (and in any event within 24 hours) in writing, of such Acquisition Proposal, inquiry, proposal, offer or request, including a description of its material terms and conditions, the identity of all Persons making the Acquisition Proposal, inquiry, proposal, offer or request and copies of all agreements, documents, correspondence or other material received in respect of, from or on behalf of such Person; and (c) shall keep the Purchaser fully informed of the status of discussions and negotiations with respect to such Acquisition Proposal, inquiry, proposal, offer or request (to the extent permitted by the Arrangement Agreement), and any material changes, modifications or other amendments to any such Acquisition Proposal, inquiry, proposal, offer or request.

Responding to an Acquisition Proposal

Notwithstanding the Company’s covenants regarding non-solicitation above, if at any time, prior to obtaining the approval by the Company Participating Shareholders of the Arrangement Resolution, the Company receives a bona fide written Acquisition Proposal that was not solicited in contravention of the non-solicitation covenant, the Company may engage in or participate in discussions or negotiations with such Person regarding such Acquisition Proposal and provide copies of, access to or disclosure of confidential information, properties, facilities, books or records of the Company or its Subsidiaries, if and only if: (i) the Company Board first determines in good faith, after consultation with its financial advisors and its outside legal counsel, that such Acquisition Proposal constitutes or could

- 4 -

reasonably be expected to constitute or lead to a Superior Proposal; (ii) such Person was not restricted from making such Acquisition Proposal pursuant to an existing standstill or similar restriction; (iii) the Company has been, and continues to be, in compliance with its obligations under the non-solicitation covenants in all material respects; (iv) prior to providing any such copies, access, or disclosure, the Company enters into an Acceptable Confidentiality Agreement with such Person and any such copies, access or disclosure provided to such Person shall have already been (or shall concurrently be) provided to the Purchaser; and (v) the Company promptly provides the Purchaser with, prior to providing any such copies, access or disclosure, a true, complete and final executed copy of such Acceptable Confidentiality Agreement. The Arrangement Agreement does not prohibit the Company Board or the Company from making any disclosure to securityholders of the Company if the Company Board, acting in good faith and upon the advice of outside legal advisors, shall have first determined that the failure to make such disclosure would be inconsistent with the fiduciary duties of the Company Board or such disclosure is required by applicable Law, provided that (i) the Company shall provide the Purchaser and its outside legal counsel with a reasonable opportunity to review and comment on the form and content of any disclosure to be made, and shall give reasonable consideration to comments made by the Purchaser and its outside legal counsel, and (ii) notwithstanding the foregoing, the Company Board shall not be permitted to make a Change in Recommendation other than as permitted by Section 5.4 of the Arrangement Agreement.

Right to Match

If the Company receives an Acquisition Proposal that constitutes a Superior Proposal prior to the approval of the Arrangement Resolution by the Company Participating Shareholders, the Company Board may make a Change in Recommendation, if and only if: (i) the Person making the Superior Proposal was not restricted from making such Superior Proposal pursuant to an existing standstill or similar restriction; (ii) the Company has been, and continues to be, in compliance with its non-solicitation obligations in all material respects; (iii) the Company has delivered to the Purchaser a written notice of the determination of the Company Board that such Acquisition Proposal constitutes a Superior Proposal and of the intention of the Company Board to make a Change in Recommendation with respect to such Superior Proposal, including a notice as to the value in financial terms that the Company Board has, in consultation with its financial advisors, determined should be ascribed to any non-cash consideration offered under the Superior Proposal (collectively, the “Superior Proposal Notice”); (iv) the Company or its Representatives have provided to the Purchaser a copy of any proposed definitive agreement for the Superior Proposal; (v) at least five Business Days (the “Matching Period”) have elapsed from the date that is the later of the date on which the Purchaser received the Superior Proposal Notice and the date on which the Purchaser received all of the material as referred to in Section 5.4(a)(iv) of the Arrangement Agreement; (vi) during any Matching Period, the Purchaser has had the opportunity (but not the obligation), in accordance with Section 5.4(b) of the Arrangement Agreement, to offer to amend the Arrangement Agreement and the Arrangement in order for such Acquisition Proposal to cease to be a Superior Proposal; and (vii) if the Purchaser has offered to amend the Arrangement Agreement and the Arrangement under Section 5.4(b) of the Arrangement Agreement, the Company Board has determined in good faith, after consultation with the Company’s outside legal counsel and financial advisers, that such Acquisition Proposal continues to constitute a Superior Proposal compared to the terms of the Arrangement as proposed to be amended by the Purchaser under Section 5.4(d) of the Arrangement Agreement.

- 5 -

Notwithstanding any Change in Recommendation in accordance with the terms of the Arrangement Agreement, the Company shall cause the Company Meeting to occur and the Arrangement Resolution to be put to the Company Participating Shareholders thereat for consideration in accordance with the Arrangement Agreement, and the Company shall not submit to a vote of its shareholders any Acquisition Proposal other than the Arrangement Resolution prior to the termination of the Arrangement Agreement.

During the Matching Period, or such longer period as the Company may approve in writing for such purpose: (i) the Company Board shall review any offer made by the Purchaser under Section 5.4(a)(v) of the Arrangement Agreement to amend the terms of the Arrangement Agreement and the Arrangement in good faith, after consultation with outside legal counsel and financial advisors, in order to determine whether such proposal would, upon acceptance, result in the Acquisition Proposal previously constituting a Superior Proposal ceasing to constitute a Superior Proposal; and (ii) the Company shall negotiate in good faith with the Purchaser to make such amendments to the terms of the Arrangement Agreement and the Arrangement as would enable the Purchaser to proceed with the transactions contemplated by the Arrangement Agreement on such amended terms. If, as a consequence of the foregoing, the Company Board, after consultation with outside legal counsel and financial advisors, determines that such Acquisition Proposal would cease to constitute a Superior Proposal, the Company shall promptly so advise the Purchaser, and the Company and the Purchaser shall amend the Arrangement Agreement to reflect such offer made by the Purchaser, and shall take and cause to be taken all such actions as are necessary to give effect to the foregoing.

Each successive amendment or modification to any Acquisition Proposal that results in an increase in, or a modification to, the consideration (or value of such consideration) to be received by Company Participating Shareholders or other material terms or conditions thereof shall constitute a new Acquisition Proposal for the purposes of Section 5.4 of the Arrangement Agreement, and the Purchaser shall be afforded an additional five Business Day Matching Period from the date on which the Purchaser received the Superior Proposal Notice and the date on which the Purchaser received all of the materials referred to in Section 5.4(a)(iv) of the Arrangement Agreement with respect to each new Superior Proposal from the Company.

The Company Board shall promptly reaffirm the Company Board Recommendation by press release after any Acquisition Proposal which is not determined to constitute a Superior Proposal is publicly announced or the Company Board determines that a proposed amendment to the terms of the Arrangement Agreement as contemplated under Section 5.4(b) thereof would result in an Acquisition Proposal no longer constituting a Superior Proposal. The Company shall provide the Purchaser and its outside legal counsel with a reasonable opportunity to review the form and content of any such press release and shall make all reasonable amendments to such press release as requested by the Purchaser and its outside legal counsel.

- 6 -

If the Company provides a Superior Proposal Notice to the Purchaser on a date that is less than 10 Business Days before the Company Meeting, the Company may, and shall at the request of Purchaser, postpone the Company Meeting to a date that is not more than 15 Business Days after the scheduled date of the Company Meeting (and, in any event, prior to the Outside Date).

There can also be no assurance that the strategic benefits and competitive, operational and cost efficiencies expected to result from the transaction will be fully realized. In addition, if the transaction is not completed, and each of the parties continues as an independent entity, there are risks that the announcement of the transaction and the dedication of substantial resources of each party to the completion of the transaction could have an impact on such party’s current business relationships (including with future and prospective employees, customers, distributors, suppliers and partners) and could have a material adverse effect on the current and future operations, financial condition and prospects of such party.
