(b) The directors may from time to time pay to the members such interim dividends as appear to the directors to be justified by the profits of the Company. (c) No dividend shall be paid otherwise than out of profits. ( d) The directors may, before recommending any dividend, set aside out of the profits of the Company such sums as they think proper as a reserve or reserves which shall, at the discretion of the directors, be applicable for any purpose to which the profits of the Company may be properly applied, and pending such application may, at such investments ( other than shares of the Company) as the directors may from time to time think fit. The directors may also without placing the same to reserve carry forward any profits which they may think prudent not to distribute. (e) Subject to the rights of persons, if any, entitled to shares with special rights as to dividend, all dividends shall be declared and paid according to the amounts paid or credited as paid on the shares in respect whereof the dividend is paid, but no amount paid or credited as paid on the share in advance of calls shall be treated for the purposes of this Article as paid on the share. All dividends shall be apportioned and paid proportionately to the amounts paid or credited as paid on the shares during any portion or portions of the period in respect of which the dividend is paid; but if any share is issued on terms providing that it shall rank for dividend as from a particular date such share shall rank for dividend accordingly. 17

(f) The directors may deduct from any dividend payable to any member all sums of money (if any) presently payable by him to the Company on account of calls or otherwise in relation to the shares of the Company. (g) No dividend shall bear interest against the Company. 17. ACCOUNTS The directors shall from time to time determine whether and to what extent and at what times and places and under what conditions or regulations the accounts and books of the Company or any of them shall be open to the inspection of members not being directors, and no member (not being a director) shall have any right of inspecting any account or book or document of the company except as conferred by law or authorised by the directors or by the Company in general meeting. 18. CAPITALISATION OF PROFITS The Company in general meeting may upon the recommendation of the directors resolve that it is desirable to capitalise any part of the amount for the time being standing to the credit of any of the company's reserve accounts or to the profit and loss account or otherwise available for distribution, and accordingly that such sum be set free for distribution amongst the members who would have been entitled thereto if distributed by way of dividend and in the same proportions on condition that the same be not paid in cash but be applied either in or towards paying up any amounts for the time being unpaid on any shares held by such members respectively or paying up in full unissued shares or debentures of the Company to be allotted and distributed credited as fully paid up to and amongst such members in the proportion aforesaid, or partly in the one way and partly in the other, and the directors shall give effect to such resolution: Provided that a share premium account and a capital redemption reserve fund may, for the purposes of this Article, only be applied in the paying up of unissued shares to be issued to members of the company as fully paid bonus shares: Provided further that the directors may in giving effect to such resolution make such provision by payment in cash or otherwise as they think fit for the case of shares or debentures becoming distributable in fractions. 19. EXTRAORDINARY RESOLUTIONS A resolution shall be an extraordinary resolution where - (a) it has been taken at a general meeting of which notice specifying the intention to propose the text of the resolution as an extraordinary resolution and the principal purpose thereof has been duly given; and (b) it has been passed by a number of members having the right to attend and vote at any such meeting holding in the aggregate not less than fifty-one per centum (51 %) in nominal value of the shares conferring that right. 18

An extraordinary resolution shall be required for: (a) any changes to the Memorandum or Articles of Association of the Company including any change of name of the Company; (b) any reduction of the issued share capital of the Company; ( c) any conversion, amalgamation or division of or involving the Company; (d) the winding up of the Company; ( e) the registration of the Company as continued in an approved country or jurisdiction as if it had been incorporated or registered under the laws of that other country or jurisdiction; and (f) any other circumstance or instance required under the Companies Act or other applicable law. 20. WINDING UP (a) The company shall be wound up by an extraordinary resolution of the company. (b) If the Company shall be wound up the liquidator may, with the sanction of an extraordinary resolution of the Company and any other sanction required by the Companies Act, divide amongst the members "in specie" or in kind the whole or any part of the assets of the Company (whether they shall consist of property of the same kind or not) and may, for such purpose, set such value as he deems fair upon any property to be divided as aforesaid and may determine how such division shall be carried out as between the numbers of different classes of members. The liquidator may, with like sanction, vest the whole or any part of such assets in trusts for the benefit of the beneficiaries as the liquidator, with the like sanction, shall think fit, but so that no member shall be compelled to accept any shares or other securities whereon there is any liability. 21. NOTICES Notice under these Articles shall be given in accordance with this Article. Any notice must be served by registered post or telefax or telex and shall be deemed to have been served in the case of registered post on the day immediately following that on which it was posted and in the case of a telefax or a telex on the day of transmission, and in providing such service it shall be sufficient to prove that the notice was addressed properly and posted or transmitted to such telefax or telex number as may be notified by the shareholders and directors to the Company. 19

22. MEETINGS BY TELEPHONE A person is entitled to participate at a meeting of the Board of Directors or at any General Meeting by means of a telephone link provided the other members or directors agree to such participation by telephone. The chairman of the meeting, in such cases, shall sign on behalf of the person participating by telephone and shall record the fact that all persons present at the meeting have agreed to such telephonic participation. 23. INDEMNITY Every managing director, director holding any other executive office or other director, and every agent, or company secretary and in general any officer or auditor for the time being of the Company shall be indemnified out of the assets of the Company against any liability incurred by him in defending any proceedings in which judgement is given in his favour or in which he is acquitted.
