Item 5.  Other Events

         On February  26,  1999,  Oryx Energy  Company,  a Delaware  corporation
("Oryx"), was merged (the "Merger") into Kerr-McGee Corporation  ("Kerr-McGee"),
a Delaware corporation with Kerr-McGee being the surviving corporation, pursuant
to an  Agreement  and Plan of Merger,  dated as of  October  14,  1998,  between
Kerr-McGee  and  Oryx.  As a result of the  Merger  and a  reverse  stock  split
("Reverse  Split")  effected by Oryx  immediately  prior to the Merger,  (i) all
shares of common stock, par value $1.00 per share, of Oryx ("Oryx Common Stock")
owned  by  Kerr-McGee  or held by Oryx  immediately  prior  to the  Merger  were
canceled  and  retired,  and (ii) except as provided in (i),  each share of Oryx
Common Stock issued and outstanding  immediately  prior to the Reverse Split was
converted  into the right to receive  0.369  shares of common  stock,  par value
$1.00 per share, of Kerr-McGee  ("Kerr-McGee Common Stock").  The exchange ratio
of 0.369 to 1.0 was determined by negotiations  between  Kerr-McGee and Oryx. In
the  aggregate,  Kerr-McGee  is  issuing  approximately  40  million  shares  of
Kerr-McGee Common Stock. There were no material relationships between Kerr-McGee
and Oryx prior to the consummation of the merger.

                                                                     Exhibit 99
Management's Discussion and Analysis

Kerr-McGee/Oryx Merger

         On  February  26,  1999,  the merger  between  Kerr-McGee  and Oryx was
completed.  Oryx  was a  worldwide  independent  oil  and  gas  exploration  and
production  company.  Its  operations  have been merged into and  reported  with
Kerr-McGee's exploration and production segment. All references to the "company"
refer to the merged entity.

         Under the merger agreement, each outstanding share of Oryx common stock
was effectively converted into the right to receive 0.369 shares of newly issued
Kerr-McGee  common stock. The merger qualified as a tax-free  exchange to Oryx's
shareholders and has been accounted for as a pooling of interests.  Accordingly,
results of operations,  financial  position and cash flows for all prior periods
have been restated to reflect the combined  company as though it had always been
in existence.

         The  merger  was  announced  in  October 1998.  This  merger was one of
several transactions during 1998 that are discussed below.

Other 1998 Transactions

         In January 1998,  Kerr-McGee  announced its intent to focus on two core
businesses, the exploration and production of oil and gas and the production and
marketing of titanium dioxide pigment.  Several major  transactions were part of
this strategic plan.

         The  company  also  announced  its intent to exit the coal  business in
January  1998. The divestiture of the coal operations was completed in July 1998
for  approximately  $600 million cash and resulted in an after-tax  gain of $257
million. The company also disposed of its ammonium perchlorate  operation in the
first  half of  1998 in a $39  million  cash  sale.  The  gain on the  sale  was
immaterial.

         Titanium  dioxide  pigment annual  production  capacity was expanded by
approximately  55% with  the  acquisition  of an 80%  interest  in the  Bayer AG
(Bayer)  European  pigment  business.  The company has the option to acquire the
remaining  20% after  March 31,  2001.  The $97  million  cash  transaction  was
effective March 31, 1998.

         Oil and gas  production  and  exploratory  prospects  expanded with the
purchase  of the United  Kingdom oil and gas assets  of  Gulf  Canada  Resources
Limited (Gulf Canada) for $422 million.  This  transaction  was  effective March
31, 1998, and  increased  the  company's North Sea reserves by 23% compared with
year-end 1997.

Operating Environment and Outlook

         Based on proven reserves at December 31, 1998, Kerr-McGee is one of the
largest  independent,  non-integrated  oil and gas  exploration  and  production
companies  based in the  United  States.  In  connection  with the  merger,  the
company's  management  has  implemented  action plans to achieve  synergies that
should result in pre-tax benefits of $100 million annually.

         Oil  prices  in the first  five  months of 1999 rose from year end 1998
prices, their lowest level since 1985 to peak at more than $19 per barrel on the
New York  Mercantile  Exchange.  Prices were in a low range of less than $10 per
barrel to $14 per  barrel for  approximately  20 months  through  March 1999 due
primarily  to the Asian and South  American  economic  downturn  coupled with an
untimely  expansion of OPEC oil supply.  Crude oil  inventories  declined in the
early months of 1999,  which  indicated  world oil  consumption  was higher than
production. Effective April 1, 1999, OPEC took steps to reduce supplies, and the
market reacted with higher pricing.  Management recognizes that supply restraint
by OPEC and a few larger non-OPEC  producers remains a risk to commodity pricing
but believes prices should stabilize in the $15 to $18 range.

         In early 1999,  gas markets in the United States  experienced  weakened
pricing due to a warm winter and high storage volumes.  Management  believes the
severe  downturn in drilling  on the  shallow  Gulf of Mexico  shelf and onshore
United States has already reduced gas  deliverability.  This lack of investment,
the long startup time required for deepwater  projects and increasing demand for
natural gas in  environmentally  friendly power  generation  has  contributed to
higher prices in mid-1999 and should support them over the longer term.

         The  company   expanded  its  titanium   dioxide  pigment  capacity  by
approximately  55% in 1998.  Pigment  prices for 1998  increased due to economic
growth,  mainly in North  America and Europe,  rising  about 14% in the domestic
market and slightly higher in certain international markets. Management believes
that pigment  consumption will remain flat in 1999, which is likely to equate to
a flat  pricing  structure.  To  maximize  profits,  the  company  is focused on
optimizing manufacturing processes to reduce costs.

         Net income  (loss) was impacted by a number of special items in each of
the years. In 1998,  special items related  primarily to impairment  write-downs
reflecting  the current  market  value of certain of the  company's  oil and gas
producing fields and certain chemical facilities.  Other 1998 special items were
principally nonoperating and reduced net income by $22 million. In 1997, special
items were also principally nonoperating and increased net income by $8 million.
The 1996  special  items  resulted  in a charge to net income of $11 million and
were both operating and nonoperating.  These special items affect  comparability
between the periods and are shown on an after-tax basis in the following  table,
which  reconciles  income (loss) from continuing  operations  excluding  special
items to net income (loss):

         The company sold its coal operations in 1998, resulting in an after-tax
gain of $257 million.  All amounts related to coal are shown in the Consolidated
Statement of Income as discontinued operations.

         In 1997,  the company  recognized an  extraordinary  loss of $2 million
(net of $1 million of income  taxes)  from the  write-off  of  unamortized  debt
issuance  costs.  These costs related to a $500 million credit facility that was
replaced with a five-year, $500 million revolving credit agreement.

         Income (loss) from continuing  operations  excluding  special items for
1998  declined  $367  million from 1997.  This  primarily  resulted  from a $535
million decline in exploration and production operating profit excluding special
items, which was partially offset by a $31 million increase in chemical results.
In 1997, income from continuing operations excluding special items decreased $26
million  from  the  prior  year,  due  primarily  to  declines  of 15% and 7% in
operating  profit  excluding  special items of  exploration  and  production and
chemical, respectively.

         Operating profit excluding special items was $177 million, $681 million
and $789 million for 1998, 1997 and 1996, respectively. The merger of certain of
the company's North American  onshore  properties into Devon Energy  Corporation
(Devon) was effective  December 31, 1996, and affects the  comparability of 1997
and 1996 operating  profit.  The company's  investment in Devon is accounted for
using the equity  method,  and  related  results are not  included in  operating
profit  in  1998 and 1997 (see Note 4). In May 1999, Devon announced that it had
signed a definitive  agreement to merge with PennzEnergy Company. The  merger is
subject to stockholder approval by both companies, various regulatory  approvals
and other  customary  closing conditions.  Upon  successful  completion  of  the
merger, the company's investment in Devon will no longer be accounted  for using
the equity method.

         Sales  from  continuing  operations  were $2.2  billion  in 1998,  $2.6
billion in 1997 and $2.7 billion in 1996.  Declines in 1998 average sales prices
for oil and natural  gas, of 32% and 13%,  respectively,  and natural gas volume
decreases  were  partially  offset by  increased  sales  volumes  and prices for
titanium  dioxide  pigment.  The  volume  decreases  in  natural  gas sales were
primarily  the  result of  damages to and  repair  times for  pipeline  systems,
hurricane downtimes and normal production declines. Volume increases in titanium
dioxide  sales  relate to the  purchase of an 80%  interest in Bayer's  European
pigment  operations  and the  expansion  of the pigment  facility  in  Hamilton,
Mississippi. Sales for 1997 were less than the prior year due to lower crude oil
prices and  volumes,  lower  natural gas volumes  and lower  average  prices for
titanium  dioxide  pigment.  Oil and gas volumes  declined  primarily due to the
merger of certain North American onshore properties into Devon,  divestitures of
nonstrategic  properties and significantly  lower sales of natural gas purchased
from third parties.  Partially  offsetting these declines were higher prices for
natural gas and increased pigment volumes.

         Costs and operating  expenses  were $1.1  billion,  $1 billion and $1.1
billion for 1998, 1997 and 1996,  respectively.  The 1998 amount was higher than
the prior year principally due to costs of the new European  pigment  operations
and  higher  per-unit  costs  at  the  domestic  pigment  and  synthetic  rutile
facilities. This was offset by the absence of costs of natural gas purchased for
resale.  Costs and  operating  expenses for 1997 were lower than the prior year,
primarily due to the absence of certain North American  onshore and divested oil
and gas properties and significantly  lower volumes of natural gas purchased for
resale, partially offset by higher production costs for pigment.

         Following are general and  administrative  expenses for 1998,  1997 and
1996:

         The  increase in 1998 vs.  1997  general  and  administrative  expenses
primarily  resulted from  additional  costs  related to the  company's  European
pigment  operations,  which were acquired in March 31, 1998.  Net provisions for
environmental  reclamation and remediation of inactive sites primarily represent
additional  provisions  established  for the  removal of  low-level  radioactive
materials  from  the  company's  inactive  facility  and  offsite  areas in West
Chicago,  Illinois.  Restructuring  charges are for a 1998  voluntary  severance
program  for the  former  domestic  operations,  the  work  process  review  and
organizational restructuring of several groups, the 1996-1997 relocation of part
of the  exploration  and  production  unit  to  Houston,  Texas,  and  severance
associated with the divestiture program and the Devon merger.

         Asset impairments  totaled $446 million in 1998 and $25 million in 1996
(see Note 10). Of the 1998 amount,  $389 million was for  writedowns  associated
with  certain  oil and gas fields  located  in the North  Sea,  China and United
States. Asset impairment of $57 million was also recognized for certain chemical
facilities in Idaho and Alabama.  The  impairments  were recorded  because these
assets were no longer  expected to recover their net book values  through future
cash flows. The 1996 asset impairment related principally to certain oil and gas
exploration and production properties in the Gulf of Mexico.

         Exploration  costs for 1998,  1997 and 1996  were  $215  million,  $139
million and $122  million,  respectively.  The 1998  increase  was the result of
higher dry hole costs in the Gulf of Mexico,  Kazakhstan,  Thailand  and onshore
United States, higher undeveloped leasehold  amortization in the Gulf of Mexico,
higher  geophysical  expenses  related to the Gulf of Mexico and higher district
expense in China,  the North Sea and Gulf of Mexico,  partially  offset by lower
dry hole  costs in  China.  Increased  Gulf of  Mexico  leasehold  amortization,
geophysical  expenses  and lease  rentals  were the primary  reason for the 1997
increase  over the prior year.  In addition,  dry hole  expenses  were higher in
China and Algeria,  which were  partially  offset by lower dry hole costs in the
North Sea.

         Taxes,  other than income taxes, were $53 million in 1998, $103 million
in 1997 and $111 million in 1996.  The 1998  decline was due to lower  severance
taxes,  a direct  result of lower oil and gas  prices.  The decline in 1997 from
1996 was primarily due to the absence of certain  merged  onshore North American
properties,  which resulted in a decrease in proprietary  oil and gas production
volumes.

         Interest and debt expense totaled $157 million in 1998, $141 million in
1997  and  $145  million  in  1996.  Borrowings  increased  in  1998  due to the
acquisitions  of European  chemical  operations and North Sea oil and gas assets
partially  offset by the proceeds  from the sale of the coal  assets.  Decreased
debt was the  principal  reason for the lower 1997  expense,  compared  with the
prior year.

         Other  income  was as follows  for each of the years in the  three-year
period ended December 31, 1998:

         Lower equity earnings from  unconsolidated  affiliates were the primary
reason for the decline in 1998 other income  excluding  special items,  compared
with the prior year.  Equity earnings from the Devon investment were impacted by
lower oil and gas prices and decreased $14 million for 1998, compared with 1997.
In 1997,  equity earnings from Devon of $23 million  contributed to higher other
income,  as compared with 1996. In addition,  the company recorded $2 million in
foreign  currency  exchange losses in 1997,  compared with a $15 million loss in
the prior year.

additional  costs for the  segment's  restructuring  and  relocation to Houston,
Texas.  The 1996  special  items were $22 million for asset  impairment  and $10
million for  restructuring,  due to the  December  1996 merger of certain  North
American onshore properties into Devon and the announcement of the relocation of
certain exploration and production personnel to Houston, Texas.

         Asset  impairment  totaled $57 million for noncore  chemical  assets in
Alabama and Idaho in 1998 and is  included in special  items.  In  addition,  $2
million of severance  charges were  recorded as special  items in 1998.  Special
items in 1997 were primarily for the write-off of obsolete  equipment.  The 1996
amount was for impairment and shutdown  costs for a  crosstie-treating  facility
and the elimination of a product line at a specialty plant.

         Titanium  dioxide  pigment  prices  increased   throughout  1998.  This
improvement  in  pricing,  along with the  company's  acquisition  of 80% of the
104,000 net  metric-ton-per-year  European  pigment  operations from Bayer and a
full year's  production  from the 27,000  metric-ton-per-year  expansion  of the
company's  Hamilton,  Mississippi,  plant were the primary  reasons for the $173
million increase in chemical sales.  These sales increases were partially offset
by higher per-unit costs for pigment,  synthetic rutile and certain electrolytic
products,  resulting  in a $31 million  increase in operating  profit  excluding
special  items.  The  increase in 1997  sales,  compared  with 1996,  was due to
increased  titanium  dioxide  pigment and ammonium  perchlorate  sales  volumes.
Partially offsetting these increases were lower average pigment prices. Although
prices  strengthened  considerably  in the  last  half of 1997,  average  prices
received  over the year were less than those  received in 1996.  The higher 1997
pigment  volumes  resulted from the completion of the expansion at the Hamilton,
Mississippi,  plant and a full  year's  production  from the 1996  expansion  in
Western Australia.

Cash Flow

         Net cash  provided by operating  activities  was  $385 million in 1998,
compared with $1.1 billion in 1997 and $1.2 billion in 1996.

         The decrease in 1998 resulted primarily from the net loss and increased
working capital and other changes that used cash from operating activities.  Net
cash provided by operating  activities  was reduced by taxes paid related to the
sale of the discontinued coal operations of $115 million.

         The  decrease  in 1997  net  cash  provided  by  operating  activities,
compared  with 1996,  resulted  primarily  from lower net income,  lower noncash
charges, higher cash environmental expenditures and lower deferred income taxes.
Cash flow provided by operating  activities in 1997 was also adversely  affected
by the  company's  merger of certain of its North  American  onshore oil and gas
properties  into Devon,  since  undistributed  earnings  from equity  affiliates
represent a noncash item.

         In 1998,  proceeds of approximately $600 million were received from the
sale of the company's  discontinued coal operations,  $150 million from the sale
of the ammonium  perchlorate  operations and marginal exploration and production
properties  and $20 million from other  investing  activities.  These sources of
cash from  investing  activities  and net proceeds  from debt  issuances of $481
million were used for capital expenditures of $981 million,  acquisitions of the
Gulf  Canada  North  Sea  assets  and  the  European  titanium  dioxide  pigment
facilities totaling $518 million and dry hole costs of $92 million.

         In both  1997 and 1996,  cash  provided  by  operating  activities  was
supplemented  by other  sources of cash that were used  primarily to reduce debt
and purchase the company's  common stock (see Note 14). In 1997,  cash available
increased $21 million from the sale of equity  securities,  $17 million from the
sale of nonstrategic  and marginal  exploration and production  properties,  $17
million  from the sale of other  assets and $21  million  related  to  insurance
settlements. During 1996, the company received cash proceeds of $57 million from
the divestiture of nonstrategic,  marginal and other  exploration and production
properties;  $43 million related to insurance settlements;  $29 million from the
sale of equity  securities;  $13 million from the sale of the remaining refining
and marketing assets;  and $11 million from the sale of other assets,  including
the company's West Virginia coal mining operation.

         The company's Board of Directors authorized a stock purchase program in
1998. A total of 580,000  shares ($25 million) was purchased  before the program
was cancelled because of the company's  merger.  The 1995 stock purchase program
was  completed  in August 1997 with  expenditures  of $60 million in 1997,  $195
million  in 1996 and $45  million  in  1995.  A total of  4,829,000  shares  was
purchased through this program.

         On January 14, 1997, the  company's  Board  of  Directors  approved  an
increase in  the  quarterly  dividend  payable  April 1, 1997, to $.45 per share
from $.41 per share.

Liquidity

         At  year-end  1998,  total  debt  outstanding  was  $2.3  billion.  The
percentage of net debt to total capitalization was 61% at December 31, 1998, 50%
at  December  31,  1997,  and 57% at year-end  1996.  The higher  percentage  at
year-end 1998 resulted from the increase in borrowings  due to the  acquisitions
of the Gulf Canada United  Kingdom assets and the European  pigment  operations,
and capital expenditures that totaled more than the cash proceeds from the sales
of the coal  operations.  The  improvement in the 1997 percentage was the direct
result of  repayment  of debt,  which  more than  offset the effect of the stock
purchase program on total capitalization.

         In connection with the merger,  ratings agencies reviewed the company's
debt ratings.  The new ratings are "BBB+," "Baa1" and "BBB" for senior unsecured
debt. See Note 8 for a discussion of the company's debt at year-end 1998.

         The  company has the  borrowing  capacity to meet its needs and provide
for its  commercial  paper  program and general  liquidity.  In April 1999,  the
company  increased  its shelf  registration  with the  Securities  and  Exchange
Commission to offer up to $1 billion of debt securities, preferred stock, common
stock or warrants.

         The company and/or its subsidiaries  also have several revolving credit
agreements.  At year-end  1998,  $598 million was  outstanding  under  revolving
credit  facilities,  which bear interest at varying rates. At December 31, 1998,
the company had unused lines of credit and revolving credit agreements  totaling
$708  million.  Of this amount,  $345  million and $90 million  could be used to
support the commercial paper borrowings of Kerr-McGee  Credit LLC and Kerr-McGee
Oil (U.K.) PLC respectively, both wholly owned subsidiaries.

         On February 26, 1999,  the date of the merger,  the company  signed two
new revolving credit facilities replacing $75 million of a Kerr-McGee Oil (U.K.)
PLC  revolving  credit  facility and Oryx's $500  million,  five-year  revolving
credit facility entered into October 20, 1997. The two new agreements consist of
a  three-year,  $500  million  facility and a 364-day,  $250  million  facility.
Initially,  one-third of the borrowings under each of the agreements can be made
in British pound sterling,  euros or other local European  currencies.  Interest
for each of the revolving credit facilities is payable at varying rates.

         During 1998, the company and/or its subsidiaries entered into two other
revolving   credit   agreements.   One  of  the  company's   wholly  owned  U.K.
subsidiaries, Kerr-McGee Resources Limited, entered into a $76 million revolving
credit  agreement,  of which $71  million  was  outstanding  at  year-end.  This
agreement permits borrowings through May 15, 2003. Another facility entered into
during  1998  allows for the  European  operations  to borrow up to 500  million
Belgian francs (approximately $14 million). This facility is renewable annually.
At December 31, 1998, an amount equal to $8 million was  outstanding  under this
arrangement. Interest is payable at varying rates for both of these facilities.

         At December  31,  1998,  the  company  classified  $400  million of its
short-term obligations as long-term debt. Final settlement of these obligations,
consisting of revolving credit  borrowings and commercial paper, is not expected
to occur in 1999.  The company has the intent and the  ability,  as evidenced by
committed credit arrangements,  to refinance this debt on a long-term basis. The
company's practice has been to continually refinance its commercial paper, while
maintaining levels believed to be appropriate.

         The company finances capital  expenditures through internally generated
funds and various  borrowings.  Cash capital  expenditures  were $981 million in
1998,  $836 million in 1997 and $875  million in 1996, a total of $2.7  billion.
During this same  three-year  period,  $3.1  billion of net cash was provided by
operating  activities  (exclusive of working capital and other  changes),  which
exceeded  cash capital  expenditures  and  dividends  paid during the periods by
approximately $124 million.

         Management  anticipates that 1999 cash capital requirements,  currently
estimated at $545 million,  and the capital  expenditures  programs for the next
several years can continue to be provided through internally generated funds and
selective borrowings.

Market Risks

         The  company is exposed to a variety  of market  risks,  including  the
effects of movements in foreign  currency  exchange  rates,  interest  rates and
certain commodity  prices.  The company addresses its risks through a controlled
program  of  risk  management  that  includes  the use of  derivative  financial
instruments. The company does not hold or issue derivative financial instruments
for  trading  purposes.  See Notes 1 and 16 for  additional  discussions  of the
company's financial instruments and hedging activities.

Foreign Currency Exchange

         The  U.S.   dollar  is  the  functional   currency  for  the  company's
international operations, except for its European chemical operations. It is the
company's  intent to hedge a portion  of its  monetary  assets  and  liabilities
denominated in foreign currencies.  Periodically,  the company purchases foreign
currency   forward   contracts  to  provide  funds  for  operating  and  capital
expenditure  requirements  that  will  be  denominated  in  foreign  currencies,
primarily  Australian  dollars  and  British  pound  sterling.  These  contracts
generally have durations of less than three years.  The company also enters into
forward contracts to hedge the sale of various foreign  currencies,  principally
generated  from  accounts   receivable  for  titanium   dioxide   pigment  sales
denominated in foreign currencies.  These contracts are principally for European
currencies  and  generally  have  durations  of less  than a year.  Since  these
contracts  qualify as hedges and correlate to currency  movements,  any gains or
losses  resulting  from  exchange  rate changes are deferred and  recognized  as
adjustments of the hedged transaction when it is settled in cash.

         Following  are the  notional  amounts at the contract  exchange  rates,
weighted-average contractual exchange rates and estimated fair value by contract
maturity for open contracts at year-end 1998 and 1997 to purchase (sell) foreign
currencies. All amounts are U.S. dollar equivalents.

Interest Rates

         The company's  exposure to changes in interest rates relates  primarily
to long-term debt obligations.  The company has participated in various interest
rate hedging  arrangements to help manage the  floating-rate  portion of part of
its debt. At December 31, 1998, all interest rate hedging contracts had expired.
At  December  31,  1997,  the  company  was a party  to  interest  rate  hedging
agreements  having  notional  amounts of $500  million,  of which  $250  million
represented interest rate caps (caps) and $250 million represented interest rate
swaps (swaps). The company's exposure to changes in LIBOR was reduced due to the
offsetting terms of the caps and swaps (see Note 16).

         The table below presents principal amounts and related weighted-average
interest  rates by maturity date for the company's  long-term  debt  obligations
outstanding at year-end 1998. All borrowings are in U.S. dollars.

</TABLE>

         At December 31, 1997, long-term debt included fixed-rate debt of $1,509
million (fair value - $1,681 million) with a  weighted-average  interest rate of
8.18% and $232 million variable-rate debt, which approximated fair value, with a
weighted-average interest rate of 6.39%.

Commodity Prices

         The company periodically uses commodity futures and option contracts to
hedge a portion of its crude oil and natural gas sales and natural gas purchased
for  operations  in  order to  minimize  the  price  risks  associated  with the
production  and  marketing  of crude oil and natural  gas.  Since the  contracts
qualify as hedges and  correlated  to price  movements  of crude oil and natural
gas, any gain or loss from these contracts is deferred and recognized as part of
the hedged transaction.

         At December 31, 1998,  the company had open crude oil collar  contracts
to hedge  approximately  4% of its  estimated  1999  worldwide  crude  oil sales
volumes at an average  floor  price of $15.85 per barrel and an average  ceiling
price of $17.35 per barrel.  Approximately  21% of its estimated  1999 worldwide
natural gas sales  volumes were hedged using collar  arrangements  at an average
floor price of $2.29 per MMBtu and an average  ceiling price of $2.47 per MMBtu.
The aggregate  carrying  value of these  contracts at December 31, 1998,  was $7
million,  and the  aggregate  fair  value,  based on quotes  from  brokers,  was
approximately $22 million.

Environmental Matters

         The company's operations are subject to various  environmental laws and
regulations.  Under these  laws,  the company is or may be required to remove or
mitigate  the effects on the  environment  of the disposal or release of certain
chemical,  petroleum  or  low-level  radioactive  substances  at various  sites,
including  sites  that  have  been  designated   Superfund  sites  by  the  U.S.
Environmental   Protection   Agency   (EPA)   pursuant   to  the   Comprehensive
Environmental  Response,  Compensation,  and Liability Act of 1980 (CERCLA),  as
amended. At December 31, 1998, the company had received notices that it has been
named a  potentially  responsible  party (PRP) with  respect to 17 existing  EPA
Superfund  sites that require  remediation and may share liability at certain of
these sites.  In addition,  the company  and/or its  subsidiaries  have executed
consent orders, operate under a license or have reached agreements to perform or
have performed remediation or remedial investigations and feasibility studies on
sites not included as EPA Superfund sites.

         The company does not consider the number of sites for which it has been
named a PRP to be a relevant  measure of liability.  The company is uncertain as
to its  involvement  in  many  of the  sites  because  of  continually  changing
environmental laws and regulations;  the nature of the company's businesses; the
large number of other PRPs;  the present  state of the law,  which imposes joint
and several liability on all PRPs under CERCLA;  and pending legal  proceedings.
Therefore,  the company is unable to reliably  estimate the potential  liability
and the  timing  of  future  expenditures  that  may  arise  from  many of these
environmental  sites.  Reserves have been  established  for the  remediation and
reclamation  of active and inactive sites where it is probable that future costs
will be incurred and the liability is estimable.  In 1998, $91 million was added
to the  reserve  for active and  inactive  sites.  At  December  31,  1998,  the
company's reserve for these sites totaled $240 million. In addition, at year-end
1998,  the  company had a reserve of $219  million  for the future  costs of the
abandonment and removal of offshore well and production facilities at the end of
their productive  lives. In the Consolidated  Balance Sheet, $376 million of the
total reserve is classified as a deferred credit,  and the remaining $83 million
is included in current liabilities.

         Expenditures for the  environmental  protection and cleanup of existing
sites for each of the last  three  years  and for the  three-year  period  ended
December 31, 1998, are as follows:

         Management   believes   adequate   reserves   have  been  provided  for
environmental and all other known  contingencies.  However,  it is possible that
additional  reserves could be required in the future due to the previously noted
uncertainties.

Year 2000 Readiness

         In 1996, the company  established a formal Year 2000 Program  (Program)
to assess and correct  Year 2000  problems.  The Program is  organized  into two
major areas: Business Systems and Facilities Integrity. Business Systems include
replacement  and upgrade of computer  hardware  and  software,  including  major
business  applications such as purchasing,  inventory,  engineering,  financial,
human resources, etc. Facilities Integrity encompasses telecommunications, plant
process  controls,  instrumentation  and  embedded  chip  systems  as well as an
assessment of third-party Year 2000 readiness.  The Program is generally divided
into the following phases:

- -        Identification, evaluation  and  prioritization of systems that need to
         be modified or replaced.
- -        Remediation work to modify existing systems or install new systems.
- -        Testing and validation of the systems and applications.
- -        Contingency planning.

         An integral part of the Program is communication  with third parties to
assess the extent and status of their Year 2000 efforts.  Formal  communications
have  been  initiated  with  critical   suppliers  to  determine  whether  their
operations and/or the products and services provided to the company will be Year
2000 ready.  In addition,  the company has  contacted key customers and partners
requesting  information  regarding  their  Year  2000  readiness.   The  company
continues to evaluate responses and make additional inquiries as needed.

         The company is also developing  contingency  plans to address potential
failure of critical systems and/or critical  suppliers.  These plans may include
items such as activating manual systems, placing operations on standby and other
procedures to accommodate significant disruptions that could be caused by system
failures.  When appropriate,  alternative  providers are being identified in the
event that certain critical  suppliers are unable to provide an acceptable level
of service to the  company.  Contingency  plans that address  business  critical
areas are expected to be completed by the end of the 1999 third quarter.

         As of  December  31,  1998,  approximately  95% of the work on Business
Systems for the merged company had been completed.  Many of the Business Systems
projects were  undertaken to improve  business  functionality  and not solely to
address Year 2000 issues.  These  activities are  anticipated to be completed by
the end of the 1999 third quarter.

         Approximately 70% of the planned work on Facilities  Integrity has also
been  completed,  including  additional  activities  resulting  from the merger.
Critical activities are expected to be completed by the end of the third quarter
of 1999.  However,  some ongoing work in areas of  contingency  planning,  third
party communications,  auditing and year-end  communication response planning is
expected to continue through the end of 1999.

         Program  expenditures  total  approximately  $45 million from inception
through  December 31, 1998,  which  included $19 million spent during 1998.  The
total cost to achieve Year 2000 readiness is estimated to be $52 million for the
entire Program,  which is not material to the company's  consolidated results of
operations,  financial position or cash flows. Program expenditures are provided
through internally generated funds and selective borrowings.

         The failure to correct a critical system that is adversely  affected by
Year 2000 could result in  disruption  of some aspects of the  company's  normal
business  activities or operations.  Such failures could have a material adverse
effect on the  company's  results of  operations  and cash flows in a particular
quarter or annual period.  Management believes that the Program is comprehensive
and reduces Year 2000 risks  associated  with  internal  systems to a manageable
level.  Regardless  of  management's  efforts  to  assess  and  verify  internal
readiness,  there can be no assurance  that all outside  entities with which the
company does business will be Year 2000  compliant.  Failure by a third party to
remediate  Year 2000  issues in a timely  manner  could have a material  adverse
effect on the  company's  results of  operations  and cash flows in a particular
quarter or annual period.  Failure of a critical  operating or safety system, or
the failure of a key third-party supplier,  partner or customer, are believed to
be the most  reasonably  likely  worst-case  scenarios  that  could  impact  the
company.

New Accounting Standards

         In March 1998, the American  Institute of Certified Public  Accountants
issued  Statement  of  Position  (SOP) No.  98-1,  "Accounting  for the Costs of
Computer Software  Developed or Obtained for Internal Use." Amounts  capitalized
or expensed by the company for internal-use  software  projects are not expected
to differ  materially as a result of the SOP,  since the  prescribed  accounting
treatment is fairly consistent with the company's current accounting policy. The
effect of the SOP is to be  recognized  prospectively  and is effective for 1999
financial statements.

         SOP No.  98-5,  "Reporting  on the Costs of  Start-Up  Activities"  was
issued in April 1998.  It requires  that costs  related to start-up  activities,
including  organization  costs, be expensed as incurred.  The SOP was adopted in
the first quarter of 1999, and the company  recognized  approximately $6 million
($4  million  after  income  taxes) as the  cumulative  effect of the  change in
accounting  principle.  These costs were carried as deferred charges at year-end
1998.

         In June 1998, the Financial Accounting Standards Board issued Statement
No. 133,  "Accounting  for  Derivative  and Hedging  Activities."  The statement
requires recording all derivative instruments as assets or liabilities, measured
at fair value.  The standard is effective for fiscal years  beginning after June
15, 1999. An exposure  draft was issued in May 1999 to defer the effective  date
to fiscal  years  beginning  after  June 15,  2000.  The  company  is  currently
evaluating  the  impact  the  standard  will  have  on  income  from  continuing
operations;  however,  management  believes it will not be  material  due to the
limited amount of hedging activity in which the company currently engages.

Cautionary Statement Concerning Forward-Looking Statements

         The company has made certain forward-looking statements in this report,
which are subject to risks and uncertainties.  These statements are based on the
beliefs and assumptions of the company's management.  Forward-looking statements
are not  guarantees  of  performance.  Among the factors that could cause actual
results to differ  materially  are crude oil and natural  gas prices;  chemicals
prices and competitive  conditions affecting supply and demand for the company's
chemical  products;  potential  failure  to  achieve  expected  production  from
existing and future oil and gas development  projects;  potential  disruption or
interruption  of the company's  production or  manufacturing  facilities  due to
accidents or political  events;  the potential  liability  for remedial  actions
under  existing or future  environmental  regulations;  and potential  liability
resulting from pending or future litigation.  In addition, such statements could
be  affected  by general  domestic  and  international  economic  and  political
conditions.

         Certain   information   in  the  Year   2000   Readiness   section   is
forward-looking.  The  Year  2000  Program and the dates on  which  the  company
believes it will be completed are based on management's  best  estimates,  which
were derived  utilizing  numerous  assumptions of future  events,  including the
continued availability of certain resources,  third-party modification plans and
other factors. However, there can be no assurance that there will not be a delay
in, or increased  costs  associated  with, the  implementation  of the Year 2000
Program.

         Forward-looking  statements include information  concerning possible or
assumed future results and may be preceded by, followed by, or otherwise include
the words "believes," "expects,"  "anticipates," "intends," "plans," "estimates"
or similar expressions.  For those statements, the company claims the protection
of the safe  harbor for  forward-looking  statements  contained  in the  Private
Securities Litigation Reform Act of 1995.

Responsibility for Financial Reporting

         The  company's   management  is  responsible   for  the  integrity  and
objectivity of the financial data contained in the financial  statements.  These
financial  statements have been prepared in conformity  with generally  accepted
accounting principles  appropriate under the circumstances and, where necessary,
reflect  informed  judgments and estimates of the effects of certain  events and
transactions based on currently available  information at the date the financial
statements were prepared.

         The company's  management  depends on the company's  system of internal
accounting  controls  to  assure  itself  of the  reliability  of the  financial
statements.  The  internal  control  system is  designed  to provide  reasonable
assurance, at appropriate cost, that assets are safeguarded and transactions are
executed  in  accordance  with  management's  authorizations  and  are  recorded
properly to permit the  preparation of financial  statements in accordance  with
generally accepted accounting principles.  Periodic reviews are made of internal
controls by the company's staff of internal  auditors,  and corrective action is
taken if needed.

         The  Board of  Directors  reviews  and  monitors  financial  statements
through its audit  committee,  which is composed solely of directors who are not
officers or employees of the company.  The audit  committee meets regularly with
the independent public  accountants,  internal auditors and management to review
internal accounting controls, auditing and financial reporting matters.

         The independent  public accountants are engaged to provide an objective
and independent review of the company's  financial  statements and to express an
opinion  thereon.  Their  audits are  conducted  in  accordance  with  generally
accepted auditing standards, and their report is included below.


Report of Independent Public Accountants

To the Stockholders and Board of Directors of Kerr-McGee Corporation:

         We  have  audited  the  accompanying   consolidated  balance  sheet  of
Kerr-McGee  Corporation (a Delaware  corporation) and subsidiary companies as of
December 31, 1998 and 1997, and the related  consolidated  statements of income,
comprehensive  income  and  stockholders'  equity and cash flows for each of the
three years in the period ended December 31, 1998.  These  financial  statements
are the  responsibility of the company's  management.  Our  responsibility is to
express an opinion on these financial statements based on our audits. We did not
audit the financial statements of Oryx Energy Company, which was merged into the
company during 1999 in a transaction  accounted for as a  pooling of  interests,
as  discussed  in Note 1. Such  statements  are  included  in  the consolidated
financial  statements  of  Kerr-McGee  Corporation and  reflect total assets and
total revenues of 36 percent and 37 percent in 1998, respectively, total  assets
and  total  revenues  of 39  percent  and  47  percent  in  1997,  respectively,
and  total  revenues  of  43  percent  in  1996,  of  the  related  consolidated
totals,  after  restatement  to  reflect  certain  adjustments  as  set forth in
Note 24.  The  financial  statements  of  Oryx  Energy  Company  prior  to those
adjustments were audited by other auditors whose report has been furnished to us
and our opinion,  insofar as it relates to the amounts  included for Oryx Energy
Company, is based solely on the report of the other auditors.

         We conducted our audits in accordance with generally  accepted auditing
standards.  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
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits and the report of other auditors provide a reasonable
basis for our opinion.

         In our opinion,  based on our audits and the report of other  auditors,
the  financial  statements  referred to above  present  fairly,  in all material
respects,  the  financial  position of  Kerr-McGee  Corporation  and  subsidiary
companies as of December 31, 1998 and 1997, and the results of their  operations
and their cash flows for each of the three  years in the period  ended  December
31, 1998, in conformity with generally accepted accounting principles.

                        REPORT OF INDEPENDENT ACCOUNTANTS

To the Shareholders and Board of Directors, Oryx Energy Company:

         In our opinion,  the consolidated balance sheets of Oryx Energy Company
and its Subsidiaries and  the  related  consolidated  statements of income, cash
flows  and  changes  in  shareholders'  equity (not presented separately herein)
present fairly,  in all material  respects,  the consolidated financial position
of Oryx Energy Company and its Subsidiaries as of December 31, 1998 and 1997 and
the  consolidated  results of their operations and their  cash flows for each of
the three  years  in  the  period  ended  December  31,  1998 in conformity with
generally accepted  accounting  principles.  These financial  statements are the
responsibility of the Company's management;  our responsibility is to express an
opinion on these  financial  statements in accordance  with  generally  accepted
auditing  standards  which  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,   assessing  the
accounting  principles  used and  significant  estimates  made by management and
evaluating the overall  financial  statement  presentation.  We believe that our
audits provide a reasonable basis for the opinion expressed above.

Notes to Financial Statements


1.       The Company and Significant Accounting Policies

         Kerr-McGee is an energy and chemical company with worldwide operations.
It explores  for,  develops,  produces and markets crude oil and natural gas and
its chemical operations primarily produces and markets titanium dioxide pigment.
The exploration and production unit produces and explores for oil and gas in the
United  States,  United  Kingdom  sector of the  North  Sea,  Indonesia,  China,
Kazakhstan  and Ecuador.  Exploration  efforts are also  extended to  Australia,
Algeria,  Brazil, Gabon, Thailand and Yemen. The chemical unit has operations in
the United  States,  Australia,  Germany and  Belgium.  The company  also has an
equity  interest  in Devon  Energy  Corporation,  a publicly  traded oil and gas
exploration and production company (see Note 4).

         On  February  26,  1999,  the merger  between  Kerr-McGee  and Oryx was
completed.  Oryx  was a  worldwide  independent  oil  and  gas  exploration  and
production company.  Under the merger agreement,  each outstanding share of Oryx
common stock was effectively converted into the right to receive 0.369 shares of
newly  issued  Kerr-McGee  common  stock.  The  merger  qualified  as a tax-free
exchange  to Oryx's  shareholders  and has been  accounted  for as a pooling  of
interests.  In the  aggregate,  Kerr-McGee is issuing  approximately  39 million
shares of  Kerr-McGee  common stock  bringing the total  shares  outstanding  to
approximately 86 million.  Kerr-McGee's  consolidated  financial statements have
been restated for periods prior to the merger to include the operations of Oryx,
adjusted to conform to Kerr-McGee's  accounting  policies and presentation.  See
Note 24 for  additional  details  regarding  the  financial  information  of the
previously separate companies.

Basis of Presentation
         The  consolidated  financial  statements  include  the  accounts of all
subsidiary companies that are more than 50% owned and the proportionate share of
joint  ventures in which the company has an undivided  interest.  Investments in
affiliated  companies  that are 20% to 50% owned are  carried as  Investments  -
Equity affiliates in the Consolidated  Balance Sheet at cost adjusted for equity
in  undistributed  earnings.  Except for  dividends  and  changes  in  ownership
interest,  changes in equity for  undistributed  earnings  are  included  in the
Consolidated  Statement of Income. All material  intercompany  transactions have
been eliminated.

         The  preparation of financial  statements in conformity  with generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that affect the  reported  amounts of assets and  liabilities,  the
disclosure of  contingent  assets and  liabilities  at the date of the financial
statements  and the  reported  amounts  of  revenues  and  expenses  during  the
reporting period.
Actual  results  could  differ from those  estimates as  additional  information
becomes known.

Foreign Currencies
         The U.S.  dollar is considered the functional  currency for each of the
company's international operations, except for its European chemical operations.
Foreign  currency  transaction  gains or losses  are  recognized  in the  period
incurred.  The net  foreign  currency  transaction  losses in 1998 and 1997 were
immaterial.  The company recorded net foreign currency transaction losses of $15
million in 1996.

         The local  currencies  are the  functional  currencies for the European
chemical  operations.  Translation  adjustments  resulting from  translating the
functional  currency  financial  statements  into U.S.  dollar  equivalents  are
reported  separately in  accumulated  other  comprehensive  income (loss) in the
Consolidated Statement of Comprehensive Income and Stockholders' Equity.

Net Income (Loss) per Common Share
         Basic net income (loss) per share  includes no dilution and is computed
by dividing  income  available to common  stockholders  by the  weighted-average
number of common shares outstanding for the period. Diluted net income per share
is  computed  by dividing  net income by the  weighted-average  number of common
shares and common stock equivalents outstanding for the period.

         The weighted-average  number of shares used to compute basic net income
(loss) per share was  86,688,026 in 1998,  86,756,138 in 1997 and  88,053,257 in
1996.  After  adding the  dilutive  effect of the  conversion  of options to the
weighted-average  number of  shares  outstanding,  the  shares  used to  compute
diluted net income per share were  87,113,906  in 1997 and  88,505,456  in 1996.
There was no dilution for 1998 since the company incurred a loss from continuing
operations.

         Not  included in the  calculation  of the  denominator  for diluted net
income per share were 494,063 and 530,667 employee stock options  outstanding at
year-end 1997 and 1996, respectively.  The inclusion of these options would have
been  antidilutive  since  they  were  not  "in  the  money"  at the  end of the
respective years.

         The company has reserved  1,886,121 shares of common stock for issuance
to the  owners  of its  7-1/2%  Convertible  Subordinated  Debentures  due  2014
(Debentures).  The Debentures are convertible into the company's common stock at
any time prior to maturity at $106.03 per share of common stock.  The conversion
of the Debentures  was not  considered for purposes of  calculating  income loss
per share, as the impact  would have been  antidilutive to net income (loss) per
share for the periods presented.

Cash Equivalents
         The company  considers  all  investments  purchased  with a maturity of
three  months or less to be cash  equivalents.  Cash  equivalents  totaling  $58
million  in 1998 and $133  million  in 1997  were  comprised  of time  deposits,
certificates of deposit and U.S.
government securities.

Inventories
         The costs of the company's  product  inventories  are determined by the
first-in,  first-out (FIFO) method.  Inventory  carrying values include material
costs, labor and the associated indirect manufacturing  expenses.  Materials and
supplies are valued at average cost.

Property, Plant and Equipment
         Oil  and  Gas  -  Exploration   expenses,   including   geological  and
geophysical costs, rentals and exploratory dry holes, are charged against income
as incurred.  Costs of  successful  wells and related  production  equipment and
developmental  dry  holes  are  capitalized  and  amortized  by field  using the
unit-of-production method as the oil and gas are produced.

         Undeveloped  acreage costs are  capitalized and amortized at rates that
provide full  amortization  on  abandonment  of  unproductive  leases.  Costs of
abandoned leases are charged to the accumulated amortization accounts, and costs
of productive leases are transferred to the developed property accounts.

         Other - Property,  plant and  equipment is stated at cost less reserves
for  depreciation,  depletion  and  amortization.  Maintenance  and  repairs are
expensed as incurred, except that costs of replacements or renewals that improve
or  extend  the  lives  of  existing   properties  are  capitalized.   Costs  of
nonproducing mineral acreage surrendered or otherwise disposed of are charged to
expense at the time of disposition.

         Depreciation   and  Depletion  -  Property,   plant  and  equipment  is
depreciated or depleted over its estimated life by the unit-of-production or the
straight-line method. Capitalized exploratory drilling and development costs are
amortized using the  unit-of-production  method based on total estimated  proved
developed oil and gas reserves.  Amortization of producing  leasehold,  platform
costs   and   acquisition   costs  of   proved   properties   is  based  on  the
unit-of-production  method using total estimated proved reserves. In arriving at
rates under the  unit-of-production  method,  the quantities of recoverable oil,
gas and other minerals are established  based on estimates made by the company's
geologists and engineers.

         Retirements and Sales - The costs and related  depreciation,  depletion
and  amortization  reserves  are  removed  from  the  respective  accounts  upon
retirement or sale of property,  plant and equipment. The resulting gain or loss
is included in other income.

         Interest  Capitalized - The company capitalizes interest costs on major
projects  that  require  a  considerable  length of time to  complete.  Interest
capitalized in 1998, 1997 and 1996 was $28 million, $24 million and $26 million,
respectively.

Impairment of Long-Lived Assets
         Proved  oil  and  gas  properties  are  reviewed  for  impairment  on a
field-by-field  basis when facts and circumstances  indicate that their carrying
amounts may not be recoverable. In performing this review, future cash flows are
estimated by applying  estimated  future oil and gas prices to estimated  future
production,  less  estimated  future  expenditures  to develop  and  produce the
reserves.  If the sum of these  estimated  future cash flows  (undiscounted  and
without interest  charges) is less than the carrying amount of the property,  an
impairment  loss is  recognized  for the excess of the carrying  amount over the
estimated fair value of the property.

         Other assets are reviewed for  impairment  by asset group for which the
lowest level of  independent  cash flows can be  identified  and impaired in the
same manner as proved oil and gas properties.

Revenue Recognition
         Except for natural gas sales,  revenue is recognized  when title passes
to the  customer.  Natural gas  revenues  and  gas-balancing  arrangements  with
partners in natural gas wells are recognized  when the gas is produced using the
entitlements  method of  accounting  and are based on the  company's net working
interests. At December 31, 1998 and 1997, both the quantity and dollar amount of
gas balancing arrangements were immaterial.

Lease Commitments
         The company  utilizes  various  leased  properties  in its  operations,
principally for office space.  Lease rental expense was $37 million in 1998, $39
million in 1997 and $33 million in 1996.
         The aggregate  minimum  annual  rentals under  noncancelable  leases in
effect on December 31, 1998,  totaled $162 million,  of which $21 million is due
in 1999,  $19 million in 2000,  $64 million in the period 2001  through 2003 and
$58 million thereafter.

Income Taxes
         Deferred   income   taxes  are  provided  to  reflect  the  future  tax
consequences of differences  between the tax basis of assets and liabilities and
their reported amounts in the financial statements.

Site Dismantlement, Reclamation and Remediation Costs
         The company  provides for the estimated  costs at current prices of the
dismantlement and removal of oil and gas production and related facilities. Such
costs are  accumulated  over the estimated lives of the facilities by the use of
the unit-of-production method. As sites of environmental concern are identified,
the company assesses the existing conditions,  claims and assertions,  generally
related to former operations,  and records an estimated  undiscounted  liability
when  environmental  assessments  and/or  remedial  efforts are probable and the
associated costs can be reasonably estimated.

Employee Stock Option Plan
         The  company  accounts  for its  employee  stock  option plan using the
intrinsic value method in accordance with  Accounting  Principles  Board Opinion
(APB) No. 25, "Accounting for Stock Issued to Employees."

Futures, Forward and Option Contracts
         The company hedges a portion of its monetary  assets,  liabilities  and
commitments  denominated  in  foreign  currencies.   Periodically,  the  company
purchases  foreign currency forward contracts to provide funds for operating and
capital expenditure  requirements that will be denominated in foreign currencies
and sells foreign currency forward contracts to convert receivables that will be
paid in foreign  currencies to U.S.  dollars.  Since these contracts  qualify as
hedges and  correlate to currency  movements,  any gain or loss  resulting  from
market  changes is offset by gains or losses on the hedged  receivable,  capital
item or operating cost.

         In 1996,  the  company  also  entered  into  foreign  currency  forward
contracts to sell various foreign currencies in anticipation of titanium dioxide
pigment  sales   denominated  in  foreign   currencies.   These  contracts  were
marked-to-market  with the  resulting  gain or loss  reflected  in income in the
period in which the change  occurred.  There were no open  contracts at year-end
1997,  and no contracts  were entered into in 1998.  Open  contracts at year-end
1996 matured  throughout  1997. Net gains and losses on these  contracts in both
1997 and 1996 were immaterial.

         From time to time the  company  enters into  arrangements  to hedge the
impact of price  fluctuations  on  anticipated  crude oil and natural gas sales.
Gains or losses on hedging  activities are recognized in oil and gas revenues in
the period in which the hedged production is sold (see Note 16).

         The company  periodically  enters into interest rate hedging agreements
to alter the floating rate portion of its  underlying  debt  portfolio.  Advance
proceeds  received under the agreements are included in deferred credits and are
amortized as offsets to interest and debt expense over the relevant periods. The
differentials  paid or received  during the terms of such agreements are accrued
as interest  rates change and are recorded as  adjustments  to interest and debt
expense (see Note 16).

2.       Cash Flow Information

         Net cash  provided by operating  activities  reflects cash payments for
income taxes and interest as follows:

         (Millions of dollars)                         1998     1997      1996
         ---------------------                         ----     ----      ----

         Income taxes paid                             $151      $89       $78
         Interest paid                                  180      163       171

         Noncash  transactions  not reflected in the  Consolidated  Statement of
Cash Flows include  capital  expenditures  for which payment will be made in the
subsequent  year  totaling $43  million,  $19 million and $4 million at year-end
1998, 1997 and 1996, respectively;  transactions during 1997 associated with the
assignments   of  interest  of  certain  North  Sea  oil  and  gas   properties;
transactions during 1996 associated with the acquisition of additional interests
in the North  Sea;  the  revaluation  of certain  investments  to fair value and
transactions affecting deferred compensation  associated with the employee stock
ownership plan in each of the three years (see Notes 16 and 20).

         Effective  December 31, 1996,  the company  merged certain of its North
American  onshore  exploration  and  production  operations  into  Devon  Energy
Corporation  (Devon) in exchange for 9,954,000 shares of Devon common stock (see
(Note 4). This transaction  was not reflected in the  Consolidated  Statement of
Cash Flows due to its noncash nature.

3.       Inventories

         Major categories of inventories at year-end 1998 and 1997 are:

         (Millions of dollars)                              1998        1997
         ---------------------                              ----        ----

                                                            ----        ----

              Total                                         $247        $175
                                                            ====        ====

4.       Investments - Equity Affiliates

         At December 31, 1998 and 1997,  investments in equity affiliates are as
follows:

         (Millions of dollars)                              1998        1997
         ---------------------                              ----        ----

         Javelina Company                                     30          32
         National Titanium Dioxide Company Limited            18          12
         Other                                                14          16
                                                            ----        ----

              Total                                         $170        $277
                                                            ====        ====

         The company holds  9,954,000  shares of Devon common stock,  a publicly
traded oil and gas exploration and production company, representing an ownership
interest in Devon of  approximately  21% and 31% at December  31, 1998 and 1997,
respectively.  The initial 31%  investment in Devon was recorded at the carrying
value of the North American onshore properties merged into Devon at December 31,
1996. The change in ownership interest resulted from Devon's merger with a third
party, which was accounted for as a pooling of interests.  In 1998, the carrying
amount  of the  investment  in Devon  stock was  adjusted  for the  issuance  of
additional  common stock that  resulted from the merger,  and retained  earnings
were charged $51 million for the decrease in the company's  share of Devon's net
assets  resulting from the merger.  Devon also recorded a full cost writedown in
1998. The company's  proportionate  share of the writedown was $27 million.  The
market value of the  company's  investment in Devon was $305 million at December
31, 1998,  based on the closing price of Devon's common stock as reported in The
Wall Street Journal.

         Javelina   Company  and  National   Titanium  Dioxide  Company  Limited
represent  the  company's   investment   of  40%  and  25%,   respectively,   in
non-exploration and production joint ventures or partnerships.

         Following are financial  summaries of the company's equity  affiliates.
Due to  immateriality,  investments  shown as Other in the preceding  table have
been excluded from the information below.

8.       Debt

Lines of Credit and Short-Term Borrowings
         At year-end 1998, the company had available unused bank lines of credit
and revolving credit  facilities of $708 million.  Of this amount,  $345 million
and $90 million can be used to support  commercial paper borrowing  arrangements
of Kerr-McGee Credit LLC and Kerr-McGee Oil (U.K.) PLC, respectively.

         The company has  arrangements  to maintain  compensating  balances with
certain banks that provide  credit.  At year-end 1998,  the aggregate  amount of
such  compensating  balances  was  immaterial,  and the  company was not legally
restricted from withdrawing all or a portion of such balances at any time during
the year.

         Short-term  borrowings at year-end 1998  consisted of commercial  paper
totaling $28 million (6.37% average  effective  interest rate) and notes payable
totaling $8 million (3.63% average interest rate).  Outstanding at year-end 1997
was a note payable for $25 million (5.98% interest rate).

Long-Term Debt
         The company's policy is to classify certain  borrowings under revolving
credit  facilities and commercial  paper as long-term debt since the company has
the ability under certain revolving credit agreements and the intent to maintain
these  obligations  for longer than one year.  At year-end  1998 and 1997,  debt
totaling $400 million and $77 million, respectively, was classified as long-term
consistent with this policy.

         On  October  17,  1997,  the  company  replaced a $500  million  credit
facility with a five-year $500 million credit facility. As a result, the company
recognized  an  extraordinary  loss  of  $2 million (net of $1 million of income
taxes) from the write-off of unamortized debt issuance costs.

         Long-term debt consisted of the following at year-end 1998 and 1997:

9.       Contingencies

West Chicago
         In 1973, a wholly owned subsidiary,  Kerr-McGee  Chemical  Corporation,
closed the facility at West  Chicago,  Illinois,  that  processed  thorium ores.
Kerr-McGee  Chemical   Corporation  now  operates  as  Kerr-McGee  Chemical  LLC
(Chemical).  Operations resulted in some low-level radioactive  contamination at
the site  and,  in 1979,  Chemical  filed a plan  with  the  Nuclear  Regulatory
Commission (NRC) to decommission the facility. The NRC transferred  jurisdiction
of this  site to the  State of  Illinois  (the  State)  in 1990.  The  following
discusses the current status of various matters associated with the West Chicago
site.

         Closed  Facility - In 1994,  Chemical,  the City of West  Chicago  (the
City)  and  the  State   reached   agreement   on  the  initial   phase  of  the
decommissioning  plan for the closed West Chicago  facility,  and Chemical began
shipping material from the site to a licensed permanent disposal facility.

         In February  1997,  Chemical  executed an agreement with the City as to
the terms and conditions for completing the final phase of decommissioning work.
The State indicated approval of this agreement and has issued license amendments
authorizing  much of the work.  Chemical  expects the majority of the work to be
completed within five years.

         In 1992, the State enacted  legislation  imposing an annual storage fee
equal to $2 per cubic foot of byproduct material located at the closed facility.
The storage fee cannot exceed $26 million per year, and any storage fee payments
must be reimbursed to Chemical as decommissioning  costs are incurred.  Chemical
has  been  fully   reimbursed  for  all  storage  fees  paid  pursuant  to  this
legislation.  In June 1997, the  legislation  was amended to provide that future
storage fee obligations are to be offset against  decommissioning costs incurred
but not yet reimbursed.

         Offsite  Areas - The U.S.  Environmental  Protection  Agency  (EPA) has
listed four areas in the vicinity of the West  Chicago  facility on the National
Priority  List that the EPA  promulgates  under  authority of the  Comprehensive
Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) and has
designated Chemical as a potentially  responsible party in these four areas. The
EPA issued unilateral  administrative orders for two of these areas (referred to
as the  residential  areas and  Reed-Keppler  Park),  which require  Chemical to
conduct  removal  actions  to  excavate  contaminated  soils  and ship the soils
elsewhere for disposal. Without waiving any of its rights or defenses,  Chemical
has begun the cleanup of these two sites.

         Judicial  Proceedings  - In December  1996, a lawsuit was filed against
the company and Chemical in Illinois state court on behalf of a purported  class
of present and former West  Chicago  residents.  The lawsuit  seeks  damages for
alleged  diminution  in  property  values  and the  establishment  of a  medical
monitoring fund to benefit those allegedly exposed to thorium wastes originating
from the former  facility.  The case was  removed to federal  court and is being
vigorously defended.

         Government Reimbursement - Pursuant to Title X of the Energy Policy Act
of 1992  (Title X), the  United  States  Department  of Energy is  obligated  to
reimburse Chemical for certain  decommissioning and cleanup costs in recognition
of the fact that  much of the  facility's  production  was  dedicated  to United
States government contracts.  Title X was amended in 1998 to increase the amount
authorized to $140 million plus inflation  adjustments.  Through April 30, 1999,
Chemical has been reimbursed approximately $69 million under Title X.

Other Matters

         The  company's  current and former  operations  involve  management  of
regulated   materials  and  are  subject  to  various   environmental  laws  and
regulations.  These laws and  regulations  will obligate the company to clean up
various sites at which petroleum, chemicals, low-level radioactive substances or
other regulated materials have been disposed of or released. Some of these sites
have been designated  Superfund sites by the EPA pursuant to CERCLA. The company
is also a party to legal proceedings involving  environmental matters pending in
various courts and agencies. As of December 31, 1998, the company's estimate for
the cost to  investigate  and/or  remediate  all presently  identified  sites of
former or current operations,  based on currently known facts and circumstances,
totaled $240  million,  which  includes $168 million for the former West Chicago
facility,  the  residential  areas and  Reed-Keppler  Park.  Reserves  have been
established  based on this  estimate.  Expenditures  are  reduced by the amounts
recovered  under  government  programs.   Expenditures  from  inception  through
December 31, 1998, totaled $549 million for currently known sites.

         In addition  to the  environmental  issues  previously  discussed,  the
company  or its  subsidiaries  are  also a party  to a  number  of  other  legal
proceedings  pending in various  courts or  agencies  in which the  company or a
subsidiary appears as plaintiff or defendant.

         It is not possible for the company to reliably  estimate the amount and
timing of all future expenditures related to environmental matters because of:

- -        the difficulty of estimating cleanup costs;
- -             the uncertainty in quantifying  liability under environmental laws
              that  impose  joint  and  several  liability  on  all  potentially
              responsible parties; and
- -        the continually changing nature of environmental laws and regulations.

         The company provides for costs related to contingencies  when a loss is
probable and the amount is reasonably  estimable.  Although management believes,
after  consultation  with general  counsel,  that  adequate  reserves  have been
provided  for all known  contingencies,  the  ultimate  cost will  depend on the
resolution  of the  above-noted  uncertainties.  Therefore,  it is possible that
additional reserves could be required in the future.

10.      Impairment of Long-Lived Assets and Long-Lived Assets to Be Disposed Of

Assets to Be Held and Used
         At year-end 1998,  certain oil and gas fields located in the North Sea,
China and the United States and two domestic  chemical  plants were deemed to be
impaired  because the assets were no longer  expected to recover  their net book
values through future cash flows.  Expectations  of future cash flows were lower
than those previously  forecasted primarily as a result of continued weakness in
crude oil,  natural gas and certain  chemical  product prices.  Downward reserve
revisions were also deemed necessary for certain fields.

         The oil and gas  impairment  test was based on estimates of future cash
flows for each field. Crude oil price estimates were $13.00 to $14.50 per barrel
for 1999,  increasing  $.50 to $1.00 per  barrel  each year.  Natural  gas price
estimates  were $2.10 to $2.25 per MMBtu for 1999,  increasing  $.05 to $.10 per
MMBtu each year. These prices,  consistent with forecasts by investment  bankers
and industry  consultants,  were applied to production profiles developed by the
company's  engineers  using  proved  reserves at  December  31,  1998.  Probable
reserves  and  future  development  costs were  taken  into  consideration  when
justified by actual drilling and planned additional drilling.

         The chemical  impairment test was based on current prices for a variety
of different products, including vanadium compounds and fertilizers manufactured
at the Soda Springs,  Idaho,  plant and  synthetic  rutile  manufactured  at the
Mobile,  Alabama,  plant.  These prices were  escalated  based on current market
perceptions.

         The impairment loss was determined based on the difference  between the
carrying  value of the  assets  and the  present  value  of  future  cash  flows
discounted at 10%, or market value when  appropriate.  The resulting  impairment
loss  represents 10% and 9% of the carrying value of exploration  and production
and chemical assets, respectively, before the impairment.

         In  addition,  certain  oil and gas  fields in the Gulf of Mexico  were
impaired in 1996. There was no impairment loss recognized in 1997.

         Following  is the  impairment  loss for assets held and used by segment
for each of the years ended December 31, 1998 and 1996:



         (Millions of dollars)                           1998             1996

              Total                                      $446              $22

Assets to Be Disposed Of
         The company  withdrew from the ammonium  perchlorate  business in 1998.
The carrying value of these assets was approximately $9 million. The gain on the
sale was immaterial.

         During 1997, the company's  exploration  and production  operating unit
completed a program to divest a number of crude oil and  natural  gas  producing
properties considered to be nonstrategic.  Most of these properties were located
onshore in the United States;  however, some were located in the Gulf of Mexico,
Canada  and the North  Sea.  Net  gains  recognized  on the sales of  properties
included in the  divestiture  program totaled $6 million in 1997 and $13 million
in 1996.  The  divestiture  program  properties  did not  constitute  a material
portion of the  company's oil and gas  production or cash flows from  operations
for 1997 or 1996 or year-end 1996 oil and gas reserves.

         Certain  chemical  facilities  were  closed  during  1996. A $3 million
impairment loss was recognized in 1996, which reduced the carrying value of  the
assets to nil.

11.      Income Taxes

         The  taxation of a company  that has  operations  in several  countries
involves many complex  variables,  such as differing tax structures from country
to country and the effect on U.S.  taxation  of  international  earnings.  These
complexities  do not permit  meaningful  comparisons  between the  domestic  and
international  components  of income  before  income taxes and the provision for
income  taxes,  and  disclosures  of these  components  do not provide  reliable
indicators of  relationships  in future  periods.  Income (loss) from continuing
operations  before  income  taxes and  extraordinary  charge is  composed of the
following:

         The corporate tax rate in the United Kingdom  decreased to 30% from 31%
effective  April 1, 1999, and decreased to 31% from 33% effective April 1, 1997.
The deferred  income tax  liability  balance was adjusted to reflect the revised
rates, which decreased the international  deferred provision for income taxes by
$10 million in 1998 and $13 million in 1997.  The 1998,  1997 and 1996 provision
(benefit) for income taxes is summarized below:

         At  December  31,  1998,   the  company  had  foreign   operating  loss
carryforwards  totaling  $110  million - $9  million  that  expire in 2001,  $19
million  that  expire  in 2003 and $82  million  that have no  expiration  date.
Realization  of these  operating loss  carryforwards  is dependent on generating
sufficient taxable income.

         The net deferred tax asset, classified as Investments - Other assets in
the  Consolidated  Balance  Sheet,  represents the net deferred taxes in certain
foreign jurisdictions. Although realization is not assured, the company believes
it is more  likely  than not  that all of the net  deferred  tax  asset  will be
realized. Deferred tax liabilities and assets at December 31, 1998 and 1997, are
composed of the following:

         The company has 40 million shares of preferred  stock without par value
authorized, and none is issued.

         There are 1,107,692  shares of the company's common stock registered in
the name of a wholly  owned  subsidiary  of the  company.  These  shares are not
included  in the  number  of  shares  shown in the  preceding  table  and in the
Consolidated Balance Sheet.  These shares are not entitled to be voted.

         In mid-1998,  the Board of Directors authorized  management to purchase
up to $300 million of company common stock over the next three years. A total of
580,000  shares was acquired at a cost of $25 million before this stock purchase
program was cancelled  because of the merger with Oryx.  The 1995 stock purchase
program was completed in 1997 with a total of 4,829,000  shares of the company's
stock acquired in open-market transactions at a cost of $300 million.

         The company has had a stockholders-rights  plan since 1986. The current
rights plan is dated July 6, 1996,  and replaced the previous  plan prior to its
expiration. Rights were distributed under the original plan as a dividend at the
rate of one right for each share of the company's common stock.  Generally,  the
rights  become  exercisable  the earlier of 10 days after a public  announcement
that a person or group has acquired, or a tender offer has been made for, 15% or
more of the company's  then-outstanding stock. If either of these events occurs,
each right would entitle the holder (other than a holder owning more than 15% of
the outstanding stock) to buy the number of shares of the company's common stock
having a market value two times the exercise price.  The exercise price is $215.
Generally,  the rights may be redeemed at $.01 per right until a person or group
has acquired 15% or more of the company's stock. The rights expire in July 2006.

16.      Financial Instruments and Hedging Activities

Investments in Certain Debt and Equity Securities
         The company has certain investments that are considered to be available
for sale. These financial  instruments are carried in the  Consolidated  Balance
Sheet at fair value,  which is based on quoted market prices,  as Current Assets
or as Investments - Other assets, depending upon their maturity. At December 31,
1998 and 1997,  the fair  value of  available-for-sale  securities  totaled  $30
million and $27 million, respectively, which approximated cost at the end of the
periods.  The  company  held no  securities  classified  as held to  maturity or
trading at December 31, 1998 and 1997.

         During  1997 and  1996,  the  company  sold  available-for-sale  equity
securities.  Proceeds from the sales totaled $21 million in 1997 and $29 million
in 1996. The average cost of the securities was used in the determination of the
realized gains, which totaled $18 million in 1997 and $23 million in 1996 before
income taxes.  Also during 1997 and 1996,  the company  donated a portion of its
available-for-sale  equity securities to Kerr-McGee  Foundation  Corporation,  a
tax-exempt   entity   whose   purpose  is  to   contribute   to   not-for-profit
organizations. The fair value of these donated shares totaled $3 million in 1997
and $16  million in 1996,  which  included  appreciation  of $3 million  and $13
million before income taxes, respectively.

Financial Instruments for Other than Trading Purposes
         In addition to the investments previously discussed,  the company holds
or issues financial instruments for other than trading purposes. At December 31,
1998 and 1997,  the carrying  amount and estimated  fair value of such financial
instruments for which fair value can be determined are as follows:

         The  carrying  amount of cash and cash  equivalents  approximates  fair
value of those instruments due to their short maturity.  The fair value of notes
receivable  is based on  discounted  cash  flows or the fair value of the note's
collateral.  The fair value of the company's  short-term  and long-term  debt is
based on the quoted  market prices for the same or similar debt issues or on the
current rates offered to the company for debt with the same remaining  maturity.
The fair value of foreign  currency forward  contracts  represents the aggregate
replacement cost based on financial institutions' quotes.

Hedging Activities
         Most of the company's foreign currency contracts are hedges principally
for chemical's accounts receivable generated from titanium dioxide pigment sales
denominated in foreign currencies,  the operating costs and capital expenditures
of  international  chemical  operations,  and the  operating  costs and  capital
expenditures  of U.K.  oil and gas  operations.  The  purpose  of these  foreign
currency  hedging  activities  is to protect the company  from the risk that the
functional  currency amounts from sales to foreign  customers and purchases from
foreign  suppliers  could be adversely  affected by changes in foreign  currency
exchange rates. The company  recognized net foreign currency hedging gains of $4
million in 1997 and $3 million in 1996.  The net foreign  currency  hedging loss
recognized in 1998 was immaterial.

         Net unrealized losses on foreign currency  contracts totaled $7 million
at year-end 1998 and $13 million at year-end 1997. Net unrealized  gains totaled
$4 million at year-end 1996. The company's foreign currency  contract  positions
at  year-end  1998 and 1997 were as  follows:

December  31,  1998 -
 - Contracts  maturing  January  1999  through  December  2000  to purchase $113
   million Australian for $77 million and  25 million British pound sterling for
   $40 million
 - Contracts  maturing  January  through  March  1999  to  sell  various foreign
   currencies (principally European) for $2 million

December 31, 1997 -
 - Contracts  maturing  January 1998 through  December 1999 to purchase $137
   million Australian for $102 million and 31 million British pound sterling for
   $49 million
 - Contracts  maturing  January  through  April  1998  to  sell  various foreign
   currencies (principally European) for $8 million

         The  company  also   participated  in  various  interest  rate  hedging
arrangements  to help manage the floating  rate portion of part of its debt.  At
December 31, 1998, all interest rate hedging contracts had expired.  At December
31, 1997,  the company was a party to interest  rate hedging  agreements  having
notional  amounts of $500 million,  of which $250 million  represented  interest
rate caps (caps)  maturing on September 15, 1998.  The remaining $250 million at
December 31, 1997, represented interest rate swaps (swaps) expiring on September
15, 1998, that had been under option at December 31, 1994, and were subsequently
exercised  on August 15,  1995.  The terms of the caps  exposed  the  company to
interest  rate risk when LIBOR  exceeded 5 percent per year.  Under the terms of
the  caps,  the  company  received  advance  proceeds  of $19  million  from the
counterparties  and paid the  excess by which  LIBOR  exceeded  5 percent on the
notional  amounts.  Under the terms of the swaps,  the company  received advance
proceeds of $14 million from the  counterparties and paid an annual rate of 9.75
percent  while  receiving  LIBOR.  The  offsetting  terms of the caps and  swaps
reduced the  company's  exposure to changes in LIBOR.  At December  31, 1998 and
1997,  the aggregate  carrying  values of the gains  deferred from the company's
interest  rate futures  agreements  were nil and $5 million,  respectively.  The
estimated fair market value, based on market quotes, was $11 million at December
31, 1997.

         The company has periodically  used oil or natural gas futures or option
contracts to reduce the effect of the price  volatility of crude oil and natural
gas. The futures contracts permitted settlement by delivery of commodities.

         During  1998,  the company  entered  into  hedging  arrangements  for 7
million  barrels  of  crude  oil  and 61  billion  cubic  feet  of  natural  gas
representing  approximately  11% and 29% of its worldwide  crude oil and natural
gas sales volumes,  respectively.  Net hedging gains  recognized in 1998 totaled
$45 million.  The effect of the gains was to increase the company's 1998 average
gross  margin for crude oil and natural gas by $.55 per barrel and $.05 per MCF,
respectively.  At year-end 1998, open crude oil and natural gas contracts had an
aggregate  value  of $7  million,  and the  unrecognized  gain on the  contracts
totaled $15 million.

         During  1997,  the company  entered into  hedging  arrangements  for 12
million  barrels  of  crude  oil  and 75  billion  cubic  feet  of  natural  gas
representing  approximately  18% and 30% of its worldwide  crude oil and natural
gas sales volumes,  respectively.  Net hedging losses recognized in 1997 totaled
$27 million.  The effect of the losses was to reduce the company's  1997 average
gross  margin for crude oil and natural gas by $.10 per barrel and $.08 per MCF,
respectively.  At year-end 1997, open crude oil and natural gas contracts had an
aggregate  value of $2 million,  and the  unrecognized  loss on these  contracts
totaled $7 million.

         During  1996,  the company  entered into  hedging  arrangements  for 19
million  barrels  of  crude  oil and 107  billion  cubic  feet  of  natural  gas
representing  approximately  30% and 37% of its worldwide  crude oil and natural
gas sales volumes,  respectively.  Net hedging losses recognized in 1996 totaled
$117 million.  The effect of the losses was to reduce the company's 1996 average
gross  margin for crude oil and natural gas by $.77 per barrel and $.23 per MCF,
respectively.  At year-end 1996, open crude oil and natural gas contracts had an
aggregate  value of $10 million,  and the  unrecognized  loss on these contracts
totaled $13 million.

         Contract   amounts  do  not  quantify  risk  or  represent   assets  or
liabilities of the company but are used in the  calculation of cash  settlements
under the contracts.  These  financial  instruments  limit the company's  market
risks, are with major financial institutions, expose the company to credit risks
and at  times  may be  concentrated  with  certain  institutions  or  groups  of
institutions. However, the credit worthiness of these institutions is subject to
continuing review, and full performance is anticipated.  Additional  information
regarding market risk is included in Management's Discussion and Analysis.

         Year-end hedge  positions and activities  during a particular  year are
not necessarily indicative of future activities and results.

18.      Employee Stock Option Plans

         The 1998 Long Term Incentive  Plan (1998 Plan)  authorizes the issuance
of shares of the company's  common stock any time prior to December 31, 2007, in
the form of stock options, restricted stock or long-term performance awards. The
options may be accompanied by stock  appreciation  rights.  A total of 2,300,000
shares of the  company's  common stock is authorized to be issued under the 1998
Plan.

         In January 1998,  the Board of Directors  approved a broad-based  stock
option plan (BSOP) that  provides  for the  granting of options to purchase  the
company's common stock to all full-time  employees,  except officers. A total of
1,500,000 shares of common stock is authorized to be issued under the BSOP.

         The 1987 Long Term  Incentive  Program (1987  Program)  authorized  the
issuance of shares of the company's  stock over a 15-year  period in the form of
stock  options,  restricted  stock or  long-term  performance  awards.  The 1987
Program was terminated when the stockholders  approved the 1998 Plan. No options
could be granted  under the 1987 Program after that time,  although  options and
any accompanying stock appreciation rights outstanding may be exercised prior to
their respective expiration dates.

         The company's employee stock options are fixed-price options granted at
the fair market value of the  underlying  common stock on the date of the grant.
Generally,  one-third  of  each  grant  vests  and  becomes  exercisable  over a
three-year  period  immediately  following  the grant date and  expires 10 years
after the grant date.

         In connection with the merger with Oryx (see Note 1), outstanding stock
options  under the stock  option  plans  maintained  by Oryx were assumed by the
company. Stock option transactions summarized below include amounts for the 1998
Plan,  the BSOP,  the 1987 Program and the Oryx plans using the merger  exchange
rate of 0.369 for each Oryx share under option.

         Statement of Financial  Accounting  Standards(FAS) No. 123, "Accounting
for Stock-Based  Compensation," prescribes a fair-value method of accounting for
employee stock options under which compensation expense is measured based on the
estimated fair value of stock options at the grant date and recognized  over the
period that the options vest. The company,  however,  chooses to account for its
stock  option  plans under the  optional  intrinsic  value method of APB No. 25,
"Accounting for Stock Issued to Employees,"  whereby no compensation  expense is
recognized  for  fixed-price   stock  options.   Compensation   cost  for  stock
appreciation  rights,  which is recognized  under both accounting  methods,  was
immaterial for 1998, 1997 and 1996.

         Had  compensation  expense been  determined in accordance  with FAS No.
123,  the  resulting  compensation  expense  would have  affected net income and
per-share  amounts as shown in the  following  table.  These  amounts may not be
representative  of future  compensation  expense using the fair-value  method of
accounting  for  employee  stock  options as the number of options  granted in a
particular year may not be indicative of the number of options granted in future
years,  and the fair-value  method of accounting has not been applied to options
granted prior to January 1, 1995.

         The  fair  value of each  option  granted  in  1998,  1997 and 1996 was
estimated as of the date of grant using the  Black-Scholes  option pricing model
with the following weighted-average assumptions.

19.      Restructuring Charges

         Oryx  initiated a  voluntary  severance  program in 1998,  prior to the
agreement to merge with  Kerr-McGee,  for its domestic  operations.  The company
also  completed  a  work  process  review  during  1998  which  resulted  in the
elimination of nonessential  work processes,  organizational  restructuring  and
employee reductions in both the operating and staff units. The programs resulted
in the notification of approximately 260 employees that their positions would be
eliminated.

         The  restructuring  of the  Exploration  and Production  operating unit
began in 1995 with the unit's reorganization of its administrative and operating
functions  and  continued  throughout  1996 and 1997 with the  unit's  merger of
certain of its North American  onshore  properties into Devon and the relocation
of part of the unit to Houston, Texas. This program was essentially completed at
year-end 1997 except for costs  associated  with an office lease  obligation and
resulted in approximately 550 employees terminating their employment.

         During the  three-year  period ended  December  31,  1998,  the company
accrued a total of $52 million for the cost of special termination  benefits for
retiring employees to be paid from retirement plan assets,  future compensation,
relocation,  lease  cancellation  and  outplacement.  The $20 million reserve at
December 31, 1998, primarily represents remaining severance costs and $7 million
for  costs  associated  with an office  lease  obligation  that has no  economic
benefit to the  company.  The amounts are expected to be paid and charged to the
reserve during 1999.  The accruals,  expenditures  and reserve  balances are set
forth below:

20.      Employee Stock Ownership Plan

         In 1989, the company's Board of Directors approved a leveraged Employee
Stock  Ownership  Plan  (ESOP)  into  which  is  paid  the  company's   matching
contribution  for the employees'  contributions  to the  Kerr-McGee  Corporation
Savings  Investment Plan (SIP). Most of the company's  employees are eligible to
participate  in both the ESOP  and the  SIP.  Although  the ESOP and the SIP are
separate  plans,  matching   contributions  to  the  ESOP  are  contingent  upon
participants' contributions to the SIP.

         In 1989,  the ESOP trust  borrowed $125 million from a group of lending
institutions and used the proceeds to purchase approximately 3 million shares of
the company's treasury stock. The company used the $125 million in proceeds from
the sale of the stock to acquire shares of its common stock in  open-market  and
privately  negotiated  transactions.  In  1996,  a  portion  of the  third-party
borrowings was replaced with a note payable to the company (sponsor  financing).
The  third-party  borrowings  are guaranteed by the company and are reflected in
the Consolidated  Balance Sheet as Long-Term Debt,  while the sponsor  financing
does not appear in the company's balance sheet.

         The company stock acquired by the ESOP trust is held in a loan suspense
account.  Deferred  compensation,  representing the unallocated ESOP shares,  is
reflected  as a  reduction  of  stockholders'  equity.  The  company's  matching
contribution  and  dividends  on the  shares  held by the ESOP trust are used to
repay the loan,  and stock is  released  from the loan  suspense  account as the
principal  and interest are paid.  The expense is  recognized  and stock is then
allocated  to  participants'  accounts  at  market  value  as the  participants'
contributions  are made to the SIP.  Long-term  debt is reduced as payments  are
made on the  third-party  financing.  Dividends paid on the common stock held in
participants' accounts are also used to repay the loans, and stock with a market
value equal to the amount of dividends is allocated to participants' accounts.

         The Oryx Capital  Accumulation Plan (CAP) is a combined stock bonus and
leveraged ESOP available to substantially all U.S.  employees of the former Oryx
operations.  On August 1, 1989,  Oryx  privately  placed  $110  million of notes
pursuant to the  provisions  of the CAP.  Oryx  loaned the  proceeds to the CAP,
which used the funds to purchase  Oryx common  stock and were placed in a trust.
Stock is  released by the trust as the loan  principal  and  interest  are paid.
Stock is allocated to  participants  on a quarterly basis as the loan is repaid.
The  number  of  shares  allocated  to each  participant  is  determined  by the
proportion each participant's  contributions bear to the total  contributions of
all  participants.  Deferred  compensation,  representing  the  unallocated  CAP
shares, is reflected as a reduction of stockholders'  equity.  Prior to 1995 and
resuming in 1997, the CAP made scheduled loan payments using Oryx  contributions
to the  CAP.  In 1995  and  1996,  repayments  were  deferred  pending  a ruling
requested from the Internal Revenue Service.  The company plans to merge the CAP
into the ESOP and SIP.

         Shares of stock  allocated to the ESOP and CAP  participants'  accounts
and in the loan suspense are as follows:

         (Thousands of shares)                       1998             1997
         ---------------------                      -----            -----

         Participants' accounts                     1,736            1,832
         Loan suspense account                      1,610            1,848

         The shares allocated to ESOP and CAP participants at December 31, 1998,
included  approximately  52,000 shares released in January 1999, and at December
31, 1997, included approximately 15,000 shares released in January 1998.

         All ESOP and CAP  shares  are  considered  outstanding  for net  income
per-share  calculations.  Dividends  on ESOP  shares  are  charged  to  retained
earnings.

         Compensation expense is recognized using the cost method and is reduced
for dividends paid on the unallocated ESOP shares.  The company  recognized ESOP
and  CAP-related  expense of $17  million,  $13 million and $15 million in 1998,
1997 and 1996, respectively.  These amounts include interest expense incurred on
the third-party  ESOP debt of $5 million in both 1998 and 1997 and $6 million in
1996.  The company  contributed  $16 million,  $12 million and $9 million to the
ESOP and CAP in 1998, 1997 and 1996,  respectively.  The cash  contributions are
net of $4 million for the  dividends  paid on the company stock held by the ESOP
trust in each of the years 1998, 1997 and 1996.

21.      Employee Benefit Plans

         The company has both noncontributory  defined-benefit  retirement plans
and company-sponsored contributory postretirement plans for health care and life
insurance.  Most employees are covered under the company's retirement plans, and
substantially  all U.S.  employees  may become  eligible for the  postretirement
benefits if they reach retirement age while working for the company.
Following are the changes in the benefit obligations during the past two years:

         The  benefit  amount that can be covered by the  retirement  plans that
qualify  under the Employee  Retirement  Income  Security Act of 1974 (ERISA) is
limited by both ERISA and the Internal Revenue Code. Therefore,  the company has
unfunded  supplemental  plans designed to maintain benefits for all employees at
the plan formula level and to provide senior executives with benefits equal to a
specified percentage of their final average compensation. The benefit obligation
for the unfunded  retirement plans was $109 million and $107 million at December
13, 1998 and 1997, respectively.  Although not considered plan assets, a grantor
trust was  established  from which  payments  for certain of these  supplemental
plans are made.  The trust had a balance of $10 million at year-end  1998 and $7
million at year-end 1997. The postretirement plans are also unfunded.

         Following  are the changes in the fair value of plan assets  during the
past two years and the reconciliation of the plans' funded status to the amounts
recognized in the financial statements at December 31, 1998 and 1997:

         The following assumptions were used in estimating the actuarial present
value of the plans' benefit obligations and net periodic expense:

                                        1998          1997         1996
                                        ----          ----         ----

Discount rate                          6.75%   6.5% - 7.0%  7.3% - 7.5%
Expected return on plan
     assets                      9.0% - 9.5%   9.0% - 9.5%  9.0% - 9.5%
Rate of compensation
     increases                   4.0% - 5.0%   4.0% - 5.0%  4.0% - 5.0%

         The health care cost trend rates used to determine  the  year-end  1998
postretirement  benefit obligation was 5.7% to 7.5% in 1999, gradually declining
to 4.5% to 5% in the year 2008 and  thereafter.  A 1%  increase  in the  assumed
health  care  cost  trend  rate  for  each  future  year  would   increase   the
postretirement  benefit  obligation  at December  31,  1998,  by $17 million and
increase  the  aggregate  of the service and  interest  cost  components  of net
periodic  postretirement  expense for 1998 by $1  million.  A 1% decrease in the
trend rate for each future year would reduce the benefit  obligation at year-end
1998 by $16 million. It was not practical to calculate the effect of the percent
decrease on net periodic expense in the health care cost trend rate.

22.      Reporting by Business Segments

         The  company  is  managed  in  two  industry  segments:   oil  and  gas
exploration and production and  manufacturing  and marketing of titanium dioxide
pigment.  The  exploration and production unit produces and explores for oil and
gas in the United States,  United  Kingdom  sector of the North Sea,  Indonesia,
China,  Kazakhstan  and  Ecuador.  Exploration  efforts  are  also  extended  to
Australia,  Algeria,  Brazil,  Gabon,  Thailand and Yemen.  The chemicals  group
manufactures  and  markets  primarily  titanium  dioxide  pigment,  as  well  as
electrolytic chemicals and forest products. The chemicals segment has operations
in the United States, Australia, Germany and Belgium.

         There were no individually significant customers in 1998, 1997 or 1996.
Sales to subsidiary companies are eliminated as described in Note 1.

23.      Discontinued Operations

         The company exited from the coal business in 1998 with the sales of its
mining operations at Galatia,  Illinois, and Kerr-McGee Coal Corporation,  which
held  Jacobs  Ranch Mine in  Wyoming.  The cash sales  resulted  in  proceeds of
approximately  $600 million.  Coal assets and  liabilities at December 31, 1997,
are included as part of the appropriate line items in the  Consolidated  Balance
Sheet.  Included at  December  31,  1997,  are  current  assets of $50  million;
property,  plant and  equipment  of $216  million;  other  assets of $4 million;
current  liabilities  of $40 million and long-term  liabilities  of $73 million.
Summarized financial information for discontinued operations for the three years
ended December 31, 1998, is as follows:

</TABLE>


         Merger  adjustments   reflect  conforming   accounting  policy  changes
primarily related to the following:

a.       Financial   Accounting   Standards  (FAS)  No.  106,  "Accounting   for
         Postretirement  Benefits  Other Than Pensions," allowed for recognition
         of the postretirement  transition  obligation either immediately in net
         income as a change in  accounting  principle in  the period of adoption
         or on a delayed  basis as a  component of net  periodic  postretirement
         benefit cost. Kerr-McGee adopted FAS 106  in 1992 and elected immediate
         recognition of its transition  obligation.  Oryx  adopted the statement
         at the  beginning  of 1993 and  elected  to  delay  recognition  of its
         transition obligation,  amortizing the amount on  a straight-line basis
         over  20   years.  The  adjustment  to  immediately   recognize  Oryx's
         transition  obligation  increased   pre-tax  income by $9  million,  $3
         million  and $4  million  for  the  years  ended  1998,  1997 and 1996,
         respectively.

b.       Kerr-McGee  and Oryx  use  different  methods  to  recognize  Petroleum
         Revenue Tax (PRT) for U.K.  operations.  Kerr-McGee estimates the total
         PRT to be payable  over the life of a field and charges  this amount to
         income  tax  expense  on a  unit-of-production  basis.  Oryx  used  the
         flow-through  method, which recognizes PRT as a production tax in total
         costs and expenses as amounts become currently payable.  The adjustment
         to provide for PRT using the life-of-field  method decreased net income
         $12 million in 1998 and increased net income  $31 million in  1997  and
         $36  million  in 1996.

         Oryx  reduced  the amount of its  estimated  dismantlement  and removal
         costs by the amount of PRT expected to be  recovered  when the field is
         abandoned.  (Under the life-of-field method, this amount is included in
         the estimate of total PRT payable over the field life).  To provide for
         dismantlement  costs  similar  to  Kerr-McGee,  operating  expense  was
         increased  $14 million,  $15 million and $9 million for the years ended
         1998,  1997,  and 1996,  respectively.

c.       Kerr-McGee and Oryx use different  methods to provide for  nonproducing
         leasehold cost impairment.  Kerr-McGee capitalizes  undeveloped acreage
         costs and amortizes  the costs at rates that provide full  amortization
         upon  abandonment/expiration  of unproductive  leases. Oryx capitalized
         undeveloped  acreage costs but recognized  abandonment of  unproductive
         leaseholds when the lease expired or when circumstances  indicated.  To

26.      Capitalized Costs of Crude Oil and Natural Gas Activities

         Capitalized  costs of crude  oil and  natural  gas  activities  and the
related reserves for depreciation, depletion and amortization at the end of 1998
and 1997 are set forth in the table below. Not included in the amounts shown are
$221 million that  represent  the company's  proportional  interest in an equity
affiliate's net  capitalized  costs at December 31, 1998 and 1997, (see Note 4).
The equity  affiliate  follows the "full cost" method of accounting  for oil and
gas exploration and production activities.

27.      Standardized  Measure  of  and  Reconciliation of Changes in Discounted
         Future Net Cash Flows (Unaudited)

         The  standardized  measure of future net cash  flows  presented  in the
following  table was computed using year-end prices and costs and a 10% discount
factor.  The future income tax expense was computed by applying the  appropriate
year-end  statutory  rates,  with  consideration  of future  tax  rates  already
legislated,  to the  future  pre-tax  net cash  flows  less the tax basis of the
properties  involved.  However, the company cautions that actual future net cash
flows  may vary  considerably  from  these  estimates.  Although  the  company's
estimates of total reserves,  development  costs and production rates were based
upon the best information  available,  the development and production of the oil
and gas reserves may not occur in the periods  assumed.  Actual prices  realized
and costs  incurred  may vary  significantly  from those used.  Therefore,  such
estimated  future  net  cash  flow  computations  should  not be  considered  to
represent the company's  estimate of the expected  revenues or the current value
of existing proved reserves.

28.      Crude Oil, Condensate and Natural Gas Net Reserves (Unaudited)

         The  estimates of proved  reserves  have been prepared by the company's
geologists  and  engineers  in  accordance  with  the  Securities  and  Exchange
Commission  definitions.  Such estimates include reserves on certain  properties
that are partially  undeveloped  and reserves that may be obtained in the future
by improved recovery operations now in operation or for which successful testing
has been  demonstrated.  The  company  has no proved  reserves  attributable  to
long-term  supply  agreements with  governments or consolidated  subsidiaries in
which there are  significant  minority  interests.  At December  31,  1996,  the
company merged certain of its North American  onshore  properties into an equity
affiliate (see Note 4).

         The following table summarizes the changes in the estimated  quantities
of the company's crude oil and condensate and natural gas reserves for the three
years ended December 31, 1998.

             equip  development  wells and to  acquire,  construct  and  install
             production  facilities and improved recovery  systems.  Development
             costs also include costs of developmental dry holes.

         (4)During 1998, the equity affiliate  merged with a third party,  which
             reduced the  company's  ownership  interest in the  affiliate.  The
             company's proportionate interest reflects its ownership interest at
             the respective year-end (see Note 4).

30.      Quarterly Financial Information (Unaudited)

         A  summary  of  quarterly  consolidated  results  for  1998 and 1997 is
presented  below.  In  periods  in  which  there  was  a  loss  from  continuing
operations,  the  conversion  of stock  options was not  assumed  since the loss
per-share  amount  would have been lower.  Therefore,  the  quarterly  per-share
amounts may not add to the annual amounts. Refer to Management's  Discussion and
Analysis for information about special items.
