Item 7.  Financial Statements and Exhibits.

(a)  Financial Statements of Businesses Acquired.

     Audited financial statements for Tosco Corporation (Tosco)
     for the years ended December 31, 2000 and 1999, are filed
     herewith as Exhibit 99.1 and incorporated herein by
     reference.  Unaudited financial statements for Tosco for the
     six-month period ended June 30, 2001, are filed herewith as
     Exhibit 99.2 and incorporated herein by reference.

(b)  Pro Forma Financial Information.

     Basis of Presentation

     The following unaudited pro forma financial statements
     reflect Phillips' purchase of Tosco for approximately
     $7 billion, plus the assumption of approximately $2 billion
     of Tosco debt.  The acquisition was effective September 14,
     2001, and is being accounted for as a purchase business
     combination.  The following unaudited pro forma financial
     information represents the combination of the consolidated
     historical financial statements of Phillips and Tosco.  The
     unaudited pro forma income statement information for the
     year ended December 31, 2000, and the six-month period ended
     June 30, 2001, was prepared assuming the Tosco acquisition
     occurred January 1, 2000.  However, during the year ended
     December 31, 2000, Phillips and Tosco entered into other
     transactions that are not fully reflected in the companies'
     historical income statements for the year ended December 31,
     2000.  Therefore, the pro forma income statement for the
     year ended December 31, 2000, has been further adjusted on a
     pro forma basis to reflect: (1) Phillips' March 31, 2000,
     Duke Energy Field Services, LLC (DEFS) transaction as
     reported in Phillips' Current Report on Form 8-K filed on
     April 13, 2000; (2) Phillips' acquisition of Atlantic
     Richfield Company's (ARCO) Alaskan businesses completed in
     two phases on April 26, 2000, and August 1, 2000, as
     reported in Phillips' Current Reports on Form 8-K filed on
     May 18, 2000, and August 10, 2000; (3) Phillips' July 1,
     2000, Chevron Phillips Chemical Company LLC (CPChem)
     transaction as reported in Phillips' Current Report on Form
     8-K filed on July 14, 2000; and (4) Tosco's August 31, 2000,
     disposition of its Avon refinery as reported in its Current
     Report on Form 8-K filed on September 15, 2000, as if all
     had occurred on January 1, 2000.  The unaudited pro forma
     balance sheet information at June 30, 2001, was prepared as
     if the Tosco transaction had occurred June 30, 2001.


                                 1





     This pro forma financial information is not intended to
     reflect results from operations or the financial position
     which would have actually resulted had the combinations been
     effective on the dates indicated.  Moreover, this pro forma
     information is not intended to be indicative of the results
     of operations or financial position which may be achieved in
     the future.

     This pro forma financial information should be read in
     conjunction with the historical financial statements
     included in Phillips' Annual Report on Form 10-K for the
     year ended December 31, 2000, as amended; the financial
     disclosures included in Phillips' Quarterly Report on
     Form 10-Q for the six-month period ended June 30, 2001; the
     historical Tosco financial statements for the years ended
     December 31, 2000, and 1999, included in this Form 8-K/A
     filing as Exhibit 99.1; and Tosco's financial disclosures
     for the six-month period ended June 30, 2001, included in
     this Form 8-K/A filing as Exhibit 99.2.  The pro forma
     adjustments use estimates and assumptions based on currently
     available information.  Management believes that the
     estimates and assumptions are reasonable, and that the
     significant effects of the transactions are properly
     reflected.  However, actual results may materially differ
     from this pro forma financial information.

     The preliminary purchase price allocation may be subject to
     revision once additional information on the fair value of
     Tosco's assets and liabilities becomes available.  Actual
     purchase accounting adjustments may therefore differ from
     the pro forma adjustments presented here.

Notes to Unaudited Pro Forma           Phillips Petroleum Company
Financial Statements


(a)  The Phillips and Tosco pro forma combined income statement
     information for the year ended December 31, 2000, has been
     further adjusted on a pro forma basis to reflect four
     significant transactions that were consummated during 2000:

     o The disposition of Phillips' gas gathering, processing
       and marketing business, and the simultaneous acquisition
       of a 30.3 percent equity interest in DEFS on March 31,
       2000;
     o The acquisition of ARCO's Alaskan businesses, completed
       in two phases on April 26, and August 1, 2000;
     o The disposition of Phillips' chemicals business, and the
       simultaneous acquisition of a 50 percent equity interest
       in CPChem on July 1, 2000; and
     o The disposition of Tosco's Avon refinery on August 31,
       2000;

     as if they had occurred January 1, 2000.

     The significant pro forma adjustments that were made for the
     DEFS and CPChem transactions were:

     o The removal of Phillips' chemical and gas gathering,
       processing, and marketing businesses from consolidation;
     o The inclusion of Phillips' estimated 50 percent and
       30.3 percent equity interest earnings from CPChem and
       DEFS, respectively, based on the pro forma financial
       results of those two entities prior to their inception;
       and
     o The amortization of the basis difference between the book
       value of Phillips' contributions to DEFS and CPChem, and
       its equity in the two entities.

     For additional information about these two transactions,
     including pro forma financial presentations, see Phillips'
     Current Report on Form 8-K filed on April 13, 2000, related
     to the DEFS transaction; and Phillips' Current Report on
     Form 8-K filed on July 14, 2000, related to the CPChem
     transaction.

     The significant pro forma adjustments that were made for the
     acquisition of ARCO's Alaskan businesses were:


                                 6





     o Estimated income statement impacts resulting from the
       purchase price allocation to the Alaskan assets and
       liabilities--for example, increased depreciation due to
       the step-up of the property, plant and equipment to fair-
       market value.  These preliminary purchase price
       allocations continued to be refined during 2000 and into
       2001;
     o The conforming of ARCO's accounting policies to
       Phillips'; and
     o An increase in interest expense due to the debt incurred
       to partially fund the acquisition.

     For additional information on this transaction, including
     pro forma financial presentations, see Phillips' Current
     Report on Form 8-K filed on May 18, 2000.

     The significant pro forma adjustments that were made for the
     Avon refinery transaction were:

     o The removal of Tosco's ownership, operations and gain
       from disposition of the Avon refinery from consolidation;
       and
     o The reduction of interest expense as a result of reducing
       long-term debt collateralized by the Avon refinery.

     For additional information on this transaction, including
     pro forma financial presentations, see Tosco's Current
     Report on Form 8-K filed on September 15, 2000.

(b)  The following is the purchase price for Tosco:

     Number of shares of Phillips common stock
       issued in the exchange...................    124.1 million
     Multiplied by Phillips' average stock
       price two days before and two days after
       the date the merger was announced........ x $55.50
                                                 --------
                                                  $ 6,886 million
     Fair value of Tosco stock options
       exchanged for 4.7 million vested Phillips
       stock options............................      153 million
     Transaction-related costs..................       42 million
                                                  -------
     Purchase price.............................  $ 7,081 million
                                                  =======

     For purposes of this pro forma analysis, the above purchase
     price has been allocated based on a preliminary assessment
     of the fair value of the assets and liabilities acquired and
     was based on Tosco's balance sheet at June 30, 2001.  Based
     on this pro forma analysis, the allocation of the purchase
     price would result in recording $7,729 million of
     properties, plants and equipment; $1,312 million of


                                 7





     identifiable intangible assets; and $2,081 million of
     goodwill.  The pro forma income statement adjustments
     reflect the estimated effects of depreciating and amortizing
     these amounts over their estimated useful lives and the
     presentation of turnaround costs as production and operating
     expense.  Goodwill, land and certain identifiable intangible
     assets are not subject to amortization but are periodically
     tested for impairment.

     Due to the non-taxable nature of this transaction, Tosco's
     tax basis in its assets carries over to Phillips.  The
     difference between the financial and tax bases is estimated
     to result in $1,980 million of net deferred tax liabilities
     in the purchase price allocation.

(c)  Includes the impact of adjusting and discounting Tosco's
     environmental liabilities and recording the corresponding
     accretion over time.

(d)  Reflects the restatement of Tosco debt to fair value and the
     corresponding reduction in interest expense as the resulting
     premium is amortized.

(e)  Reflects the February 2001 conversion of Tosco's company-
     obligated, mandatorily redeemable, convertible preferred
     securities into 9.1 million shares of Tosco common stock.

(f)  Reflects the estimated federal and state income tax effects
     of the pro forma adjustments to Tosco's pretax income.

(g)  Reflects the exchange of outstanding Tosco common stock, the
     issuance of 124.1 million shares of Phillips common stock, and
     the effect of Phillips' stock options issued in the exchange.

(h)  Includes $150 million receivable for a payment expected to
     be received in November 2001 related to the sale of the Avon
     refinery in August 2000.

(i)  Includes estimated payments under termination and change of
     control provisions in Tosco executive compensation and employment
     agreements.

(j)  Includes the reversal of a deferred gain on Tosco's balance
     sheet that is not subject to any future performance requirement,
     along with the related amortization of the deferred gain.
