For the purpose of determining whether a person is an Interested Shareholder, the voting stock of the Corporation deemed to be outstanding shall include stock deemed to be owned by the person through application of Section 11.1(i) but shall not include any other unissued stock of the Corporation which may be issuable pursuant to any agreement, arrangement or understanding, or upon exercise of conversion rights, warrants or options, or otherwise.

any stock because of such person’s right to vote such stock if the agreement, arrangement or understanding to vote such stock arises solely from a revocable proxy or consent given in response to a proxy or consent solicitation made to 10 or more persons; or

(iii) has any agreement, arrangement or understanding for the purpose of acquiring, holding, voting (except voting pursuant to a revocable proxy or consent as described in item (B) of subparagraph (ii) of this paragraph), or disposing of such stock with any other person that beneficially owns, or whose Affiliates or Associates beneficially own, directly or indirectly, such stock.

11.2 Restriction on Certain Business Combinations. Notwithstanding any other provisions contained in these Articles of Incorporation, the Corporation shall not engage in any Business Combination with any Interested Shareholder for a period of three (3) years following the time that such shareholder became an Interested Shareholder, unless:

(c) At or subsequent to such time the Business Combination is approved by the Board of Directors and authorized at an annual or special meeting, of shareholders, and not by written consent, by the affirmative vote of at least 66 2/3% of the outstanding voting stock which is not owned by the Interested Shareholder.

11.3 Exemptions. The restrictions contained in this Article XI shall not apply if:

(a) The Corporation, by action of the shareholders, adopts an amendment to these Articles of Incorporation expressly repealing this Article XI; provided that, in addition to any other vote required by law, such amendment to the Articles of Incorporation must be approved by the affirmative vote of a majority of the shares entitled to vote.

The proposed transactions referred to in the preceding sentence are limited to (x) a merger, consolidation or plan of share exchange involving the Corporation (except for a merger in respect of which, pursuant to Section 7-111-104 of the CBCA or any successor provision thereto, no vote of the shareholders of the Corporation is required); (y) a sale, lease, exchange, mortgage, pledge, transfer or other disposition (in one transaction or a series of transactions), whether as part of a dissolution or otherwise, of assets of the Corporation or of any direct or indirect majority-owned subsidiary of the Corporation (other than to any direct or indirect wholly-owned subsidiary or to the Corporation) having an aggregate market value equal to 50% or more of either that aggregate market value of all of the assets of the Corporation determined on a consolidated basis or the aggregate market value of all the outstanding stock of the Corporation; or (z) a proposed tender or exchange offer for 50% or more of the outstanding voting stock of the Corporation.
