        <footnote id="F1">The price reported in Column 4 is a weighted average price. These shares were purchased in multiple transactions at prices ranging from $75.17 to $76.165. Berkshire Hathaway Inc. (&quot;Berkshire&quot;) and the other reporting person undertake to provide Phillips 66, any security holder of Phillips 66, or the staff of the Securities and Exchange Commission, upon request, full information regarding the number of shares sold at each separate price within the range set forth in footnotes 1, 4 and 5 to this Form 4.</footnote>

(1,558,000), Berkshire Hathaway Homestate Insurance Co. (782,000), Berkshire Hathaway Specialty Insurance Co. (1,314,000) and Columbia Insurance Company (632,914).
