Report Of Independent Auditors


The Long-Term Stock Savings Plan Committee
Long-Term Stock Savings Plan of Phillips Petroleum Company

We have audited the accompanying statement of net assets
available for benefits of the Long-Term Stock Savings Plan of
Phillips Petroleum Company (Plan) as of December 31, 1999 and
1998, and the related statement of changes in net assets
available for benefits for the year ended December 31, 1999.
These financial statements are the responsibility of the Long-
Term Stock Savings Plan Committee (Committee).  Our
responsibility is to express an opinion on these financial
statements based on our audits.

We conducted our audits in accordance with auditing standards
generally accepted in the United States.  Those standards require
that we plan and perform the audit to obtain reasonable assurance
about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial
statements.  An audit also includes assessing the accounting
principles used and significant estimates made by the Committee,
as well as evaluating the overall financial statement
presentation.  We believe that our audits provide a reasonable
basis for our opinion.

In our opinion, the financial statements referred to above
present fairly, in all material respects, the net assets
available for benefits of the Plan at December 31, 1999 and 1998,
and the changes in its net assets available for benefits for the
year ended December 31, 1999, in conformity with accounting
principles generally accepted in the United States.

Our audits were performed for the purpose of forming an opinion
on the financial statements taken as a whole.  The accompanying
supplemental schedules of assets held for investment purposes at
end of year as of December 31, 1999, and reportable transactions
for the year then ended, are presented for purposes of additional
analysis and are not a required part of the financial statements
but are supplementary information required by the Department of
Labor's Rules and Regulations for Reporting and Disclosure under
the Employee Retirement Income Security Act of 1974.  These
supplemental schedules are the responsibility of the Committee.
The supplemental schedules have been subjected to the auditing
procedures applied in our audits of the financial statements and,
in our opinion, are fairly stated in all material respects in
relation to the financial statements taken as a whole.

Notes To Financial Statements        Long-Term Stock Savings Plan
                                    Of Phillips Petroleum Company

Note 1--Plan Description

The following description of the Long-Term Stock Savings Plan of
Phillips Petroleum Company (Plan) is subject to and qualified by
the more complete information appearing in the Plan document.

The Plan became effective July 1, 1988, and is a defined
contribution stock bonus plan available to certain employees of
Phillips Petroleum Company and participating subsidiaries
(Company).  Generally, any person on the U.S. direct dollar
payroll of the Company is eligible to participate, except
non-managerial retail marketing outlet employees and certain
other employee classifications.

Vanguard Fiduciary Trust Company, P.O. Box 2900, Valley Forge,
Pennsylvania 19482-2900, is the Plan Trustee.  Plan investments
are held by the Trustee in the Temporary Fund, Fund K (also known
as the Employee Stock Fund), Fund L (also known as the Employer
Stock Fund) and Fund EP (also known as the EP Stock Fund).
Temporary Fund investments consist of specified short-term
securities in the Vanguard Prime Money Market Fund.  Funds K, L
and EP are invested primarily in the common stock of Phillips
Petroleum Company (Phillips Stock).

Fund L consists of Phillips Stock, purchased with the proceeds of
the loans described in Note 3 (Leveraged Shares), with certain
Company contributions, or with certain dividends received from
the Company.  The Leveraged Shares are allocated to Fund L or
Fund EP accounts of eligible participants in one of three types
of stock allocations:  semiannual basic allocations, dividend
replacement allocations and supplemental allocations.  A basic
allocation of 477,876 shares is made as of June 30 and
December 31 each year, through 2005.  In December 1995, the
Company extended the Plan to the year 2015.  Without the
extension, allocations of stock to employees would have been
completed in 2005 or before.  The new extension will require
additional shares of Phillips Stock to be delivered to the Plan.
After 2005 and through the allocation date following the date the
second loan is repaid, the number of shares to be allocated
semiannually on each basic allocation date will be 3,877 shares
for each 100 employees eligible to make deposits as of the
preceding allocation date.

The Plan is eligible to receive shares from the Company's
Compensation and Benefits Trust (CBT).  In 1999, the Company
utilized the CBT to contribute 767,605 shares of Phillips Stock
to the Plan.  The fair value of the shares was $36 million.


                                6

<PAGE>



A participant's semiannual basic allocation is based on the ratio
of the participant's Fund K before-tax deposits to all eligible
participants' before-tax deposits for the allocation period.  If
the Company does not elect to make a special contribution and if
eligible dividends from participants' Fund L or Fund EP accounts
are used to make loan payments, participants will receive a
dividend replacement allocation.  The Plan used $20.2 million in
dividends on allocated shares to make loan payments and allocated
427,492 shares in dividend replacement allocations to
participants' Fund L and Fund EP accounts in 1999.  A
supplemental allocation is made each year end if all shares
released for allocation, based on loan payment provisions, have
not been allocated.  No supplemental allocation was required in
1999.

The Company makes contributions to the Plan which, when
aggregated with certain Plan dividends from Fund L, certain
dividends from Fund EP and certain interest earnings from Fund L,
equal the amount necessary to enable the Plan to make its
regularly scheduled payments of principal and interest due on its
loans.  The Company may also elect to make contributions to the
Plan, as an alternative to utilizing the dividends from shares in
Fund EP or from Loan 1 (see Note 3) allocated shares in Fund L.
Finally, the Company may make contributions to the Plan in the
amount necessary to bring the number of shares of stock released
for allocation up to the level required to complete the basic
allocation by contributing cash or by contributing Phillips
Stock.

Eligible employees may elect to have their salaries reduced and
before-tax deposits made by the Company on their behalf equal to
1 percent of pay.  These deposits are first placed into the
Temporary Fund and remain there until the valuation date on or
about the 20th day of the following month when they are
transferred into the employee's Fund K account.  Interest earned
on deposits while in the Temporary Fund is credited monthly to
each participant who still maintains an account in the Plan and
who made deposits during the month.  The interest of participants
in each fund is represented by units allocated to them.

Assets of the Employee Stock Ownership Plan of Phillips Petroleum
Company (ESOP) and the Payroll Stock Ownership Plan of Phillips
Petroleum Company (PAYSOP), which were merged into the Plan on
July 1, 1988, are held in Fund EP.

Participants are always vested in their deposits and amounts
credited to their accounts.  Total withdrawals from Funds K, L
and EP may be made upon the occurrence of specified events,
including the attainment of age 59 1/2 (after December 31, 1998,
for Funds EP and L) or separation from service.  Partial
withdrawals are permitted in cases of specified financial


                                7

<PAGE>



hardship and certain other cases.  For a participant who retires
or becomes totally disabled, unless a request for withdrawal is
made as of any earlier date, distribution generally will be
deferred to a date not later than the first valuation date in
October of the year age 69 is attained.  If the participant dies,
distribution to a surviving spouse beneficiary will be deferred
to the first valuation date in October in the year in which the
participant would have attained age 69.  This deferral is
revocable by the participant or the surviving spouse.
Distributions to non-spouse beneficiaries may be deferred
approximately five years.  A participant may elect a direct
rollover of the taxable portion of most distributions to an
Individual Retirement Account or another tax-qualified plan.

The Plan is administered by the Long-Term Stock Savings Plan
Committee, the members of which are appointed by the Board of
Directors of Phillips Petroleum Company (Phillips).  Members of
the Committee serve without compensation, but are reimbursed by
the Company for necessary expenditures incurred in the discharge
of their duties.  Administrative expenses of the Plan are paid by
the Trustee from assets of the Plan to the extent allowable by
law, unless paid by the Company.  In January 1999, reimbursement
of administrative expenses for plan years 1996 and 1997 was paid
to Phillips from Fund EP totaling $74,061.  Plan administrative
expenses of approximately $145,000 were paid by Phillips to the
Trustee in 1999.


Note 2--Use of Estimates

The preparation of financial statements in conformity with
accounting principles generally accepted in the United States
requires estimates and assumptions that affect the amounts
reported in the financial statements and accompanying notes and
schedules.  Actual results could differ from those estimates.


Note 3--Securities Acquisition Loans

The Plan borrowed $250 million (Loan 1) and $400 million (Loan 2)
in 1988 and 1990, respectively, and purchased 14,336,918 and
14,159,292 shares of common stock from Phillips, respectively.
The shares are held in a Fund L suspense account until allocated
to eligible participants based on the provisions of the Plan.  At
December 31, 1999 and 1998, the market value of unallocated
shares was $475 million and $457 million, respectively.  The
amount of total assets that was not allocated to participants at
December 31, 1999 and 1998, was $476 million and $463 million,
respectively.


                                8

<PAGE>



Loan 1
Loan 1 was fully repaid in June 1998, after the final principal
payment of $28 million was made.  Loan 1 provided for variable
interest rates.  The weighted-average interest rate for 1998 was
4.8717 percent.

Loan 2
Loan 2 was amended late in 1995 to extend its term from 15 to
25 years, requiring repayment in annual installments beginning in
2005, through the year 2015.

Any participating bank in the syndicate of lenders may cease to
participate on December 5, 2004, by giving not less than 180 days
prior notice to the Plan and Phillips.  Also, each bank
participating in the loan has the optional right, if the current
directors of Phillips or their approved successors cease to be a
majority of the Board of Directors, and upon not less than
90 days notice, to cease to participate in the loan.  Under the
above conditions, such banks' rights and obligations under the
loan agreement must be purchased by Phillips if not transferred
to another bank of Phillips' choice.

The outstanding balance of Loan 2 at December 31, 1999, was
$378 million.  Loan 2 provides for variable interest rates.  The
rates were 6.375 percent and 5.5 percent at December 31, 1999 and
1998, respectively.

Loan 2 is guaranteed by Phillips.  It is being repaid through
contributions made by the Company, dividends on certain allocated
and unallocated shares, and earnings on the short-term investment
of dividends.  Loan 2's carrying amount approximates fair value.


Note 4--Investments

Phillips Stock is valued at fair value, using the New York Stock
Exchange closing quoted market price.  Money market funds are
valued at cost, which approximates fair market value.


Note 5--Tax Status

The Internal Revenue Service (IRS) determined on January 16,
1996, that the Plan is qualified under Section 401(a) of the
Internal Revenue Code of 1986 and the Trust is exempt from
federal income tax under Section 501(a).  Subsequent amendments
have been adopted, but are not expected to affect the qualified
status of the Plan.  The Committee is not aware of any activity
that would affect the qualified status of the Plan.
