The written notice to the Offeror shall include a copy of any written notice, proposal, request, offer or communication, in whatever form received. The Company shall also provide such other details of the proposed notice, proposal, request, offer, communication or any amendment to the foregoing as the Offeror may reasonably request. The Company shall keep the Offeror fully informed on a timely basis of the status, including any change to the material terms, of any such Alternative Transaction, any further notice, proposal, request, offer or communications in respect thereof, including copies of any further or other documents relating to such Alternative Transaction forthwith upon receipt thereof, or the termination of such notice, proposal, request, offer or communication;

Any such adjustments (if any) shall be in the discretion of the Offeror at such time. The Board of Directors shall review any proposal by the Offeror to amend the terms of its Offer in order to determine, in good faith in the exercise of its fiduciary duties (after receiving the advice of its Financial Advisor and outside legal advisors), whether the Offeror's proposal to amend the Offer would result in the Alternative Transaction not being a Superior Proposal. In the event that the Board of Directors or any committee thereof withdraws, modifies or changes its recommendation in favour of the Offeror or the Board of Directors or any committee thereof approves or recommends acceptance of an Alternative Transaction, the Company shall forthwith notify the Offeror orally to be followed by a written notice within 24 hours;

The Offeror and its advisors shall be given an opportunity to review and comment on the press release and updated Directors' Circular and Schedule 14D-9 prior to its filing, release or printing, as applicable. In the event an Alternative Transaction is announced or publicly made by a party other than the Offeror and such Alternative Transaction is an unsolicited take-over bid, notwithstanding the foregoing, the Offeror may, not less than three (3) Business Days after such offer is made or publicly announced, request and the Board of Directors of the Company shall, within two (2) Business Days following such request, reaffirm this Agreement and its recommendation regarding the Offer;
(e): the Company acknowledges and agrees that each successive material modification to any Alternative Transaction that may lead to or constitute a Superior Proposal shall require an additional notice by the Company under Section 2.5(a) and an opportunity to make adjustments to the Offer under Sections 2.5(b) and 2.5(c) provided however that the notice period shall be three (3) Business Days;
(f): the Company shall ensure that the Company Representatives are aware of the provisions of this Section 2.5 and the Company shall be responsible for any breach of this Section 2.5 by any of the Company's Representatives; and

If, within 120 days after the date of the Offer, the Offer has been accepted by Shareholders holding not less than 90% of the outstanding Shares, excluding Shares held at the date of the Offer by or on behalf of the Offeror, or an Affiliate or associate of the Offeror, the Offeror may, to the extent possible, acquire the remainder of the Shares from those Shareholders who have not accepted the Offer pursuant to the statutory right of acquisition pursuant to Section 206 of the CBCA (the "Compulsory Acquisition"). If that statutory right of acquisition is not available or Offeror chooses not to avail itself of such statutory right of acquisition, Offeror covenants that it will use its commercially reasonable efforts to pursue other means of acquiring the remaining Shares not tendered to the Offer as soon as practicable, but in any event, not later than 120 days after the Expiry Time for consideration per Share at least equal in value to the consideration paid by the Offeror under the Offer. The Company agrees that, upon the Offeror taking up and paying for more than a simple majority of the outstanding Shares (on a Diluted Basis) under the Offer, it will assist the Offeror in acquiring the balance of the Shares by such means as may be determined by the Offeror, including by way of amalgamation, statutory arrangement, capital reorganization or other transaction of the Company and the Offeror or an Affiliate of the Offeror (a "Subsequent Acquisition Transaction") for consideration per Share at least equal in value to the consideration paid by the Offeror under the Offer.
