To: Phillips Domestic Employees

On December 14, 1995, the Compensation and Benefits Arrangements Stock Trust
("CBT") was established for the Company to use in its sole discretion to meet
its obligations with respect to various compensation and benefits arrangements.
The CBT holds approximately 27.9 million shares of the Company's common stock.
The Trustee for the CBT is Vanguard Fiduciary Trust Company ("Trustee").

Under the terms of the CBT, the Trustee is required to seek voting instructions
for the CBT shares from domestic and certain foreign employees of the Company
and subsidiaries who participate in Company stock-related benefit plans and
arrangements.

Enclosed is the Voting Direction card. If you choose to exercise this
opportunity to vote, your vote will be given equal weight to that of all
employees who elect to vote, and those directions will govern the Trustee's vote
of approximately 95 percent of the 27.9 million shares. The remaining CBT
shares will be voted by foreign employees under similar arrangements.

These 27.9 million shares in the CBT represent approximately 10 percent of
Phillips stock eligible to be voted at the Special Stockholders Meeting on
April 11, 2001. These shares, combined with the approximately 12 percent stock
ownership held by the Thrift Plan of Phillips Petroleum Company and the Long-
Term Stock Savings Plan of Phillips Petroleum Company, give employees a strong
voice in the direction of the Company.

come before the meeting, all as described in the Joint Proxy

held in the CBT, that I become a directing fiduciary of the CBT for voting such
shares; and that I may decline to accept the responsibility of a directing
fiduciary as to such shares by NOT completing and returning this Voting

appointment as a directing fiduciary and any shares in the CBT that you
otherwise could have directed will be directed by other eligible employees who
