North Atlantic Management AS, a corporation organized under the laws of Norway, with head office at Løkkeveien 107, 4001 Stavanger, Norway (“North Atlantic”).

WHEREAS Seadrill has reorganized its activities in the North Atlantic Region and, as part of such reorganization, it is in both Parties’ current best interest that drilling activities within the North Atlantic Region be primarily developed by North Atlantic, and that drilling activities outside the North Atlantic Region be primarily developed by members of the Seadrill Group other than North Atlantic; and

Opportunity, should North Atlantic not exercise the North Atlantic Preemptive Right.  In such notification, Seadrill will grant to North Atlantic a reasonable term for North Atlantic to exercise the North Atlantic Preemptive Right, taking into consideration, in establishing such term, the time necessary to take the required actions to pursue the North Atlantic Business Opportunity and other conditions for such opportunity.
