(1 )Operation of the scheme was delayed from April 2008 due to a market enforced
prolonged period during which the Board were prohibited from dealing in, and
making awards over, Centrica shares. In accordance with the rules of the scheme,
the performance period will run from April 2008 until April 2011.

(2) 20% of gross bonus (before the deduction of income tax and National
Insurance contributions) was automatically deferred and invested in Centrica
shares. Participants had the opportunity to make a further investment, funded
from net annual performance bonus, so that the maximum total investment (on a
gross basis) was 50% of the individual's maximum bonus entitlement for 2007.

(3) The calculation of the conditional matching shares was made on a gross
basis. Investment shares are grossed up for the calculation of the matching
shares so that the deferred and investment shares are matched on the same basis.

(4 )The number of matching shares that vest will be determined on a
straight-line basis over a three-year period. The maximum two for one match will
be achieved for cumulative economic profit growth of 25% or more with zero
matching for no growth.
