Dear Oslo Stock Exchange,

We act as an Investment Manager for a number of commingled funds and separate accounts (our "Clients"). In acting for our Clients, we are given full discretion over their investments. 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.

As a result of the recent sales in Petroleum Geo-Services, this has resulted in our having control over the following shares and voting rights (also see attached):
