whole or a specified portion of the Shares to which such Options relate.
 (b)

a specified proportion of the Shares held by each holder of Shares the Board shall be
entitled, at its discretion and notwithstanding anything herein contained or any condition
imposed pursuant to Clause 7 (b), to require Participants to exercise Options held by them

12.
    
    All Shares issued on any exercise of an Option shall rank pari passu in all respects with the
Shares already in issue.
 BONUS AND RIGHTS ISSUES
 13.
    
    If an allotment of Shares is made to the holders of Shares credited as fully paid up and by
way of capitalisation of reserve or a consolidation or subdivision or a reduction of the
ordinary share capital of the Company each Participant shall surrender every Option held by
him which has not been entirely exercised and be granted in its place an Option at the same
total Option Price (or otherwise have his Option adjusted) and in all other respects on
identical terms in respect of such number of Shares that the ratio between that number of
Shares and the total number of issued Shares shall be the same as the ratio between the number
of Shares to which the surrendered Option (or as the case may be the unexercised portion
thereof) related and the total number of issued shares immediately prior to the said allotment
by way of capitalisation of reserves or consolidation or subdivision or reduction of the share
capital of the Company.14.
    
    If holders of Shares are granted rights to subscribe for further shares (such rights being
related to the number of Shares held by them respectively) the Board shall at its absolute
discretion decide whether the granting of such rights and the subscriptions made thereunder
shall result in the depletion in the value of each Share and if the Board so decides each
Participant shall be entitled to surrender every Option held by him which has not been
entirely exercised and to be granted in its place an Option at the same total Option Price (or
otherwise have his Option adjusted) and in all other respects on identical terms in respect of
such number of Shares as shall in the opinion of the Board be appropriate having regard to the
said depletion in the value of each Share and having obtained the advice of the auditors to
the Company.
 SAME TIME FOR GRANT AND EXERCISE
 15.
    
    Any Option granted in place of a surrendered Option as aforesaid (or otherwise adjusted)
shall be exercised at the same time as such surrendered Option and shall for all purposes of
the Scheme be deemed (as from the date of granting thereof) to have been granted at the same
time as such surrendered Option.
 EXCHANGE OF CERTIFICATES
 16.
    
    On any surrender of an Option as aforesaid the Participant shall deliver to the Company the
Option Certificate in respect of the Option being surrendered and the Company shall deliver in
exchange an Option Certificate in respect of the Option being granted in its place.

liquidation at their absolute discretion determine) Participants shall not be entitled to
damages or other compensation of any kind.
 EXCHANGE QUOTATIONS

unconditionally authorised to allot Shares pursuant to Options to Nominated Persons in
accordance with the provisions of Section 20 Companies (Amendment) Act, 1983 or any statutory
modification or re-enactment thereof, and so that the provisions of Section 23 of the said
