The co-opted members shall be less than one half of the total membership of the committee and a resolution of any committee shall be effective only if a majority of the members present are directors.

The inclusion of the word "director" in the designation or title of any such office or employment shall in no way imply that the holder is a director of the company, and the holder shall not thereby be empowered in any respect to act as, or be deemed to be, a director of the company for any of the purposes of the articles. DECISION-MAKING BY DIRECTORS 9.

(2) If: (a) the company only has one director; and (b) no provision of the articles requires it to have more than one director, the general rule does not apply, and the director may take decisions without regard to any of the provisions of the articles relating to directors' decision-making, save that he shall comply with the requirements of article 19. 10. Unanimous decisions (1) A decision of the directors is taken in accordance with this article when all eligible directors indicate to each other by any means that they share a common view on a matter.

In determining whether directors are participating in a directors' meeting, it is irrelevant where any director is or how they communicate with each other. (3) If all the directors participating in a meeting are not in the same place, they may decide that the meeting is to be treated as taking place wherever any of them is. In default of such a decision, the meeting shall be deemed to take place where the largest group of those participating is assembled, or, if there is no such group, where the chainnan of the meeting is. 13. Quorum for directon' meetings ( 1) At a directors' meeting, unless a quorum is participating, no proposal is to be voted on, except a proposal to call another meeting.

(5) A statutory declaration by a director or the secretary (if any) that the declarant is a director or the secretary and that a share has been sold to satisfy the company's lien on a specified date: (a) is conclusive evidence of the facts stated in it as against all persons claiming to be entitled to the share; and (b) 39.

Liability to pay calls (l) Liability to pay a call is not extinguished or transferred by transferring the shares in respect of which it is required to be paid.

(2) For the purposes of this article: (a) LONDOCS\3162808.01 the "call payment date" is the time when the call notice states that a call is payable, unless the directors give a notice specifying a later date, in which case the "call payment date" is that later date; 16

(3) The relevant rate must not exceed by more than 5 percentage points the base lending rate most recently set by the Monetary Policy Committee of the Bank of England in connection with its responsibilities under Part 2 of the Bank of England Act 1998. (4) The directors may waive any obligation to pay interest on a call wholly or in part. 43. Notice of intended forfeiture A notice of intended forfeiture: 44. 45.

Directon' power to forfeit shares If a notice of intended forfeiture is not complied with before the date by which payment of the call is required in the notice of intended forfeiture, the directors may decide that any share in respect of which it was given is forfeited, and the forfeiture is to include all dividends or other moneys payable in respect of the forfeited shares and not paid before the forfeiture. Effect of forfeiture (I) Subject to the articles, the forfeiture of a share extinguishes: (a) all interests in that share, and all claims and demands against the company in respect of it; and (b) all other rights and liabilities incidental to the share as between the person whose share it was prior to the forfeiture and the company. (2) Any share which is forfeited in accordance with the articles: (a) is deemed to have been forfeited when the directors decide that it is forfeited; (b) is deemed to be the property of the company; and (c) may be sold, re-allotted or otherwise disposed of as the directors think fit.
