Appendix for Castrol heritage participants

The following provisions apply to employees who are classified as Castrol heritage participants. Unless specifically stated in this section, all other provisions of the cash balance formula apply.

Castrol heritage participant

Generally, a Castrol heritage participant is someone who was an active participant in the Burmah Castrol Group USA Pension Plan, Burmah Castrol Specialty Chemicals Pension Plan, or the Non-Salaried Employees’ Retirement Plan of Dussek Campbell Inc. (Castrol heritage plans) as of December 31, 2003, and became a BP employee on January 1, 2004 (or was rehired with less than a one year break in service).

Participation

Castrol heritage participants became participants in the BP Retirement Accumulation Plan (RAP) effective January 1, 2004.

Opening Account

If you are a Castrol heritage participant, a BP RAP Opening Account balance was established for you on January 1, 2004.

Generally speaking, your Opening Account balance is based on a lump sum present value of the benefit you earned in the Castrol heritage plan through December 31, 2003.

Employees rehired after December 31, 2003 and on or before December 31, 2014, after a one-year break in service, who have an accrued benefit and did not previously receive a distribution will also receive an Opening Account balance upon being rehired. At benefit commencement, this Opening Account balance will be compared to your prior Castrol benefit and the larger amount will be added to your Current Account.

For details on how the Opening Account balances were calculated contact BP Retirement Services at Fidelity at 1-877-272-3334.

Current Account

If you are a Castrol heritage participant, your Current Account began on January 1, 2004.
