                         Participation of B.E. Grote
               in BP America, Inc, Share Appreciation Plan 1988

The information provided in the table below reflects an approximate,
hypothetical benefit to Byron E. Grote for his participation in the BP America,
Inc, 1988 Share Appreciation Plan ('the Plan'). The theoretical values shown on
the table depend on the following assumptions: fulfilment of any applicable
corporate performance pre-conditions to payment; an assumed exercise date of 2
August 2000; and the assumed exercise price shown in Column 4. Under the Plan,
the measurement of any benefit is the appreciation, if any, of the American
Depositary Share ('ADS share') price during the period from the date of grant to
the exercise date. Any actual appreciation is payable in cash or American
Depositary Shares at the grantee's election on the exercise date. Each grant has
a period of 10 years, subject to an initial vesting period. Future values
realised may vary significantly from the values estimated under these
assumptions and will depend upon corporate performance and the excess of the
share price over the grant price on the date of exercise. 

Any fractional dollar of share amount has been rounded using standard rounding
conventions.
