(2) Subject to sections 65 and 67 of the Act, the shareholders of the Corporation may by ordinary resolution at an annual or a special meeting remove any director before the expiration of his term of office and may, by a majority of the votes cast at the meeting, elect any person in his stead for the remainder of his term.

(3) Each shareholder entitled to vote at an election of directors has the right to cast a number of votes equal to the number of votes attached to the shares held by him multiplied by the number of directors to be elected, and he may cast all such votes in favour of one candidate or distribute them among the candidates in any manner.

(4) A separate vote of shareholders shall be taken with respect to each candidate nominated for director unless a resolution is passed unanimously permitting two (2) or more persons to be elected by a single resolution.

(5) If a shareholder has voted for more than one candidate without specifying the distribution of his votes among the candidates, he shall be deemed to have distributed his votes equally among the candidates for whom he voted.

(6) If the number of candidates nominated for director exceeds the number of positions to be filled, the candidates who receive the least number of votes shall be eliminated until the number of candidates remaining equals the number of positions to be filled.

(7) A retiring director shall retain office until the adjournment or termination of the meeting at which his successor is elected unless such meeting was called for the purpose of removing him from office as a director in which case the director so removed shall vacate office forthwith upon the passing of the resolution for his removal.

The attendance of a director at a meeting of directors is a waiver of notice of the meeting except where a director attends a meeting for the express purpose of objecting to the transaction of any business on the grounds that the meeting is not lawfully called.

15. Telephone Participation. A director may participate in a meeting of directors or of a committee of directors by means of such telephone or other communication facilities that permit all persons participating in the meeting to hear each other, and a director participating in such a meeting by such means shall be deemed to be present at that meeting.

18. Resolution in lieu of meeting.

The confirmation of any such resolution or resolutions by the shareholders shall not be required. The directors shall also be entitled to be paid their travelling and other expenses properly incurred by them in connection with the affairs of the Corporation.

TO SHAREHOLDERS FOR APPROVAL

FOR THE PROTECTION OF DIRECTORS AND OFFICERS

23. No director or officer for the time being of the Corporation shall be liable for the acts, receipts, neglects or defaults of any other director or officer or employee of the Corporation or for joining in any receipt or act for conformity or for any loss, damage or expense happening to the Corporation through the insufficiency or deficiency of title to any property acquired by order of the board of directors for or on behalf of the Corporation or for the insufficiency or deficiency of any security in or upon which any of the moneys of or belonging to the Corporation shall be placed out or invested or for any loss or damage arising from the bankruptcy, insolvency or tortious act of

any person, firm or corporation including any person, firm or corporation with whom or which any moneys, securities or effects of the Corporation shall be lodged or deposited or for any loss, conversion, misapplication or misappropriation of or any damage resulting from any dealings with any moneys, securities or other assets belonging to the Corporation or for any other loss, damage or misfortune whatever which may happen to the Corporation in the execution of the duties of his respective office of trust or in relation thereto, unless the same shall happen by or through his failure to exercise the powers and to discharge the duties of his office honestly, in good faith with a view to the best interests of the Corporation, and in connection therewith to exercise the care, diligence and skill that a reasonably prudent person would exercise in comparable circumstances, provided that nothing herein contained shall relieve a director or officer from the duty to act in accordance with the Act or regulations made thereunder or relieve him from liability for a breach thereof. The directors for the time being of the Corporation shall not be under any duty or responsibility in respect of any contract, act or transaction whether or not made, done or entered into in the name or on behalf of the Corporation, except such as shall have been submitted to and authorized or approved by the board of directors. If any director or officer of the Corporation shall be employed by or shall perform services for the Corporation, the fact of his being a shareholder, director or officer of the Corporation shall not disentitle such director or officer or such firm or body corporate, as the case may be, from receiving proper remuneration for such services.

INDEMNITIES TO DIRECTORS AND OTHERS

24. Subject to section 81 of the Act, except in respect of an action by or on behalf of the Corporation or Another Body Corporate (as hereinafter defined) to procure a judgement in its favour, the Corporation shall indemnify each director and officer of the Corporation and each former director and officer of the Corporation and each person who acts or acted at the Corporation’s request as a director or officer of Another Body Corporate, and his heirs and legal representatives, against all costs, charges and expenses, including any amount paid to settle an action or satisfy a judgment, reasonably incurred by him in respect of any civil, criminal or administrative action or proceeding to which he is made a party by reason of being or having been a director or officer of the Corporation or Another Body Corporate, as the case may be, if

(a) he acted honestly and in good faith with a view to the best interests of the Corporation; and

(b) in the case of a criminal or administrative action or proceeding that is enforced by a monetary penalty, he had reasonable grounds for believing that his conduct was lawful.

“Another Body Corporate” as used herein means a body corporate of which the Corporation is or was a shareholder or creditor.

27. Remuneration and Removal of Officers. Subject to the articles or any unanimous shareholder agreement, the remuneration of all officers, employees and agents appointed by the directors may be determined from time to time by resolution of the directors. The fact that any officer, employee or agent is a director or shareholder of the Corporation shall not disqualify him from receiving such remuneration as may be so determined. The directors may by resolution remove any officer, employee or agent at any time, with or without cause.

28. Duties of Officers may be Delegated.

He shall sign such contracts, documents or instruments in writing as require his signature and shall have such other powers and duties as may from time to time be assigned to him by resolution of the directors or as are incident to his office. He may be required to give such bond for the faithful performance of his duties as the directors in their uncontrolled discretion may require, but no director shall be liable for failure to require any such bond or for the insufficiency of any such bond or for any loss by reason of the failure of the Corporation to receive any indemnity thereby provided.

If a ballot is demanded on any other question or as to the election of directors it shall be taken in such manner and either at once or later at the meeting or at an adjourned meeting as the chairman of the meeting directs. The result of a ballot shall be deemed to be the resolution of the meeting at which the ballot was demanded. A demand for a ballot may be withdrawn.

(6) Where a person holds shares as a personal representative, such person or his proxy is the person entitled to vote at all meetings of shareholders in respect of the shares so held by him.

(7) Where a person mortgages or hypothecates his shares, such person or his proxy is the person entitled to vote at all meetings of shareholders in respect of such shares unless, in the instrument creating the mortgage or hypothec, he has expressly empowered the person holding the mortgage or hypothec to vote in respect of such shares, in which case, and subject to the articles, such holder or his proxy is the person entitled to vote in respect of the shares.

(8) Where two or more persons hold the same share or shares jointly, any one of such persons present at a meeting of shareholders has the right, in the absence of the other or others, to vote in respect of such share or shares, but if more than one of such persons are present or represented by proxy and vote, they shall vote together as one on the share or shares jointly held by them.

(2) An instrument appointing a proxy shall be in writing and shall be executed by the shareholder or by his attorney authorized in writing or, if the shareholder is a body corporate, either under its seal or by an officer or attorney thereof, duly authorized. A proxy is valid only at the meeting in respect of which it is given or any adjournment thereof.

(3) Unless the Act requires another form, an instrument appointing a proxyholder shall be in the form determined by the directors from time to time.

47. Time for Deposit of Proxies. The board may by resolution specify in a notice calling a meeting of shareholders a time, preceding the time of such meeting or an adjournment thereof by not more than 48 hours excluding Saturdays and holidays before which time proxies to be used at such meeting must be deposited. A proxy shall be acted upon only if, prior to the time so specified, it shall have been deposited with the Corporation or an agent thereof specified in such notice or, if no such time is specified in such notice, only if it has been received by the secretary of the Corporation or by the chairman of the meeting or any adjournment thereof prior to the time of voting.

48. The directors may from time to time make regulations regarding the depositing of proxies at some place or places other than the place at which a meeting or adjourned meeting of shareholders is to be held and for particulars of such proxies to be sent by means of wire or wireless or any other form of transmitted or recorded communication or in writing before the meeting or adjourned meeting to the Corporation or any agent of the Corporation for the purpose of receiving such particulars and providing that proxies so deposited may be voted upon as though the proxies themselves were deposited with the Corporation at the meeting or adjourned meeting and votes given in accordance with such regulations shall be valid and shall be counted. The chairman of any meeting of shareholders may, subject to any regulations made as aforesaid, in his discretion accept wire or wireless or any other form of transmitted or recorded or written communication as to the authority of any person claiming to vote on behalf of and to represent a shareholder notwithstanding that no proxy conferring such authority has been deposited with the Corporation, and any votes given in accordance with such communication accepted by the chairman of the meeting shall be valid and shall be counted.
