LETTER TO: ELEMENTIS


LETTER DATED: 28TH JUNE 2001

We act as an Investment Manager for a number of large institutional investors
and for a number of commingled funds. In acting for our Clients, we are given
full discretion over the investments, and are empowered to vote on their behalf.
However, we do not act as their Custodian, and therefore shares are not held in
our name, but in the nominee name of their Custodian Bank.

Recent purchases/sales of shares in your company by ourselves, on behalf of our
clients, have resulted in our having control over the following shares (also see
below):

SILCHESTER:                    64,934,459         Ordinary Shares 

Our records show that you have the following shares in that class 

ELEMENTIS:                    431,400,000         Ordinary Shares 

As such, we exercise control over 15.05% of the shares of that class.
