TRC is offering to purchase up to 3 million shares, or less than 0.48% of Phillips 66’s outstanding common stock.

Phillips 66 strongly recommends investors obtain current market quotes for their shares of common stock and consult with their financial advisors with respect to TRC's offer.

Phillips 66 shareholders who have already tendered shares in the offer are advised that they may withdraw their shares as described in TRC's offer documentation prior to the expiration of the offer, which is currently scheduled for 12:01 a.m. EDT on Thursday, July 26, 2012.
