                         GENERAL DEVELOPMENT OF BUSINESS

         Kerr-McGee  Corporation,  an  energy  and  chemical  company,  had  its
beginning in 1929 with the  formation of Anderson & Kerr Drilling  Company.  The
company was  incorporated  in Delaware in 1932. With oil and gas exploration and
production as its base, the company has expanded into titanium  dioxide  pigment
manufacturing and marketing and minerals, mining and marketing.  Kerr-McGee owns
a large  inventory of natural  resources  that includes oil and gas reserves and
chemical and mineral deposits.

         For a discussion of recent business developments,  reference is made to
the  "Kerr-McGee/Oryx"  section of  Management's  Discussion and Analysis in the
1998  Annual  Report  to  Stockholders,  which  discussion  is  incorporated  by
reference in Item 7, and the Exploration and Production  discussion  included in
this Form 10-K.

                                INDUSTRY SEGMENTS

         For  information as to business  segments of the company,  reference is
made to Note 21 to the  Consolidated  Financial  Statements  in the 1998  Annual
Report to Stockholders, which note is incorporated by reference in Item 8.

                           EXPLORATION AND PRODUCTION

         Kerr-McGee  Corporation manages oil and gas operations  worldwide.  The
company acquires leases and concessions and explores for, develops, produces and
markets crude oil and natural gas through its subsidiaries, Kerr-McGee Oil & Gas
Corporation,  Kerr-McGee Oil (U.K.) PLC,  Kerr-McGee  Resources  (U.K.) Limited,
Kerr-McGee China Petroleum Ltd. and various other subsidiaries.

         The  areas of  Kerr-McGee's  offshore  oil and gas  exploration  and/or
production  activities are the Gulf of Mexico,  North Sea,  China,  Thailand and
Gabon.  Onshore exploration and/or production  operations are in Indonesia,  the
United Kingdom, Thailand and Yemen.

- ------------------

         Except as indicated under Items 1 through 3, 5 through 8 and 10 through
14, no other information appearing in either the company's 1998 Annual Report to
Stockholders  or its 1999 Proxy  Statement is deemed to be filed as part of this
annual report on Form 10-K.


         Kerr-McGee's  average daily  proprietary oil production during 1998 was
66,800 barrels, an increase of 17% from 1997. Kerr-McGee's average oil price was
$11.88 per barrel in 1998, compared with $18.51 per barrel for 1997.

         During 1998,  proprietary  natural gas sales averaged 198 million cubic
feet per day,  up 8% from 1997  sales.  The 1998  average  natural gas price was
$2.18 per thousand  cubic feet compared  with $2.56 per thousand  cubic feet for
1997.

         Kerr-McGee  continued to add to its  worldwide  prospect  inventory in
1998.   Gross  acreage  at  year-end  1998  was  more  than 27 million acres, an
increase of 47% compared with year-end 1997.

Results  of  Operations,  Sales Prices,  Production Costs, Capitalized Costs and
Costs Incurred

         Reference is made to Notes 24, 25 and 28 to the Consolidated  Financial
Statements  in  the  1998  Annual  Report  to  Stockholders,   which  notes  are
incorporated  by reference  in Item 8. These notes  contain  information  on the
results of operations from crude oil and natural gas  activities,  average sales
prices per unit of crude oil and natural gas and production  costs per barrel of
oil  equivalent  (BOE) for each of the past three  years;  capitalized  costs of
crude oil and natural gas  activities  at December 31, 1998 and 1997;  and costs
incurred  in crude oil and  natural  gas  activities  for each of the past three
years.

Reserves

         Kerr-McGee's  estimated  proved crude oil,  condensate  and natural gas
reserves  at  December  31,  1998,  and the  changes in net  quantities  of such
reserves for the three years then ended are shown in Note 27 to the Consolidated
Financial  Statements of the 1998 Annual Report to  Stockholders,  which note is
incorporated by reference in Item 8.

         From time to time reports are filed with the United  States  Department
of Energy relating to the company's reserves. The reserves reported in the Notes
to Financial  Statements are consistent with other filings  pertaining to proved
net reserves.  Minor differences in gas volumes occur due to different  pressure
bases being required in the reports.  However,  the difference in estimates does
not exceed 5% of the total estimated reserves.

Undeveloped Acreage

         As of December 31, 1998, the company had interests in  undeveloped  oil
and gas leases in the Gulf of Mexico,  the United  Kingdom and Danish sectors of
the North Sea and onshore and offshore in other international areas as follows:

Sales of Production

         All of the  company's  crude  oil and  natural  gas is  sold at  market
prices.  Kerr-McGee has formed  strategic  alliances  with two energy  marketing
companies to sell  substantially all proprietary  domestic crude oil and natural
gas production.  International crude oil is sold both under contract and through
spot market sales in the geographic area of production.

Improved Recovery

         The  company  continues  to  initiate  and/or  participate  in improved
recovery  projects where  geological,  engineering  and economic  conditions are
favorable.  As of December 31, 1998, the company was  participating in 15 active
improved recovery  projects located  principally in the United Kingdom sector of
the  North  Sea.  Most  of  the  company's   operations  outside  North  America
incorporate  water injection.  Pressure-maintenance  operations begin at or near
the time of initial production from these fields.

Merger with Oryx Energy Company

         On October 14, 1998,  Kerr-McGee  Corporation  and Oryx Energy  Company
signed a strategic  merger that was  completed on February 26, 1999.  The merger
created one of the largest  U.S.-based  independent  oil and gas exploration and
production  companies.  The  combination  resulted in  significant  additions to
Kerr-McGee's  core  exploration and production  operations in the Gulf of Mexico
and the  North  Sea  and  further  contributed  to the  company's  international
exploration efforts.

         Through the merger  Kerr-McGee added more than 600,000 net acres to the
company's  Gulf of Mexico  inventory  and several  currently  producing  fields,
including Baldpate and Neptune in deepwater. The merger also added about 225,000
net acres,  both  developed and  undeveloped,  in the North Sea. The company has
acquired  interest in eight  additional  North Sea fields and is operator of the
Ninian,  Murchison,  Hutton and Lyell  fields.  The  combined  company  also has
exploration  and/or production  operations in Ecuador,  Kazakhstan,  Algeria and
Australia.

Exploration and Development Activities

Gulf of Mexico

         Since 1947,  the Gulf of Mexico has been a major area of operation  for
Kerr-McGee and accounted for nearly 50% of  Kerr-McGee's  oil and gas production
in 1998. The company  continues  aggressive lease  acquisition,  exploration and
exploitation programs. In 1998, Kerr-McGee was awarded approximately 124,000 net
acres  through  federal and state lease sales.  About 75% of this new acreage is
located in deepwater  areas at depths ranging from 2,000 feet to more than 8,000
feet of water.  Additional deepwater acreage and exploration  opportunities were
acquired   through   the   establishment   of   a   strategic   alliance,    and
multi-disciplinary asset teams were formed to target exploitation  opportunities
in established fields.

         During 1998, three new fields started production in the Gulf of Mexico.
A summary of these and other key developments is as follows:

         Garden Banks 65 (60%):  First production from this  Kerr-McGee-operated
field began in May 1998, and development was completed in late July. At year-end
1998,  production averaged 100 million cubic feet of gas per day and 150 barrels
of oil per  day.  Kerr-McGee  leases  the  production  and  processing  facility
associated  with this  project  from a  pipeline  company,  which  significantly
reduced development cost. Additional  exploratory drilling is scheduled for 1999
on two adjacent company-operated blocks.

         Ewing Bank  910(40%):  First  production  commenced  in  December at an
initial rate of 3,500 barrels of oil per day.  Located in 560 feet of water, the
production facility is the tallest company-operated  stand-alone platform. Ewing
Bank 910 and 954 and South  Timbalier  block  320 are tied into this  production
facility. Additional development drilling and completion work are expected to be
finished in mid-1999.

         West   Cameron   638   (40%):    First   gas   production   from   this
Kerr-McGee-operated  field began in  December  1998.  This  subsea  development,
located in 375 feet of water, is expected to reach peak production in 1999.

         Pompano  Field,  Viosca Knoll 989 area (25%):  Average 1998  production
from the Pompano Field  exceeded  50,000 barrels of oil per day and more than 60
million  cubic feet of gas per day.  Processing of 4D seismic data was completed
in 1998,  and  evaluation is under way to determine the benefit from  additional
development  wells.  At year-end 1998, the 29 wells from the platform and subsea
were capable of producing about 61,000 barrels of oil per day.

North Sea

         Kerr-McGee  has been  active in the North Sea area since  1976.  In May
1998, the company  completed the purchase of the United Kingdom North Sea assets
of Gulf Canada  Resources  Limited  (GCRL),  which  significantly  increased the
company's North Sea reserve base and  production.  As a result of this strategic
acquisition  in this core area,  Kerr-McGee  now has interests in six additional
producing  fields,  and the company's  daily  production  rates in the North Sea
increased by 80% from 1997 levels. In 1998, the North Sea production represented
more than 51% of the company's  worldwide liquids  production and 19% of its gas
sales.

         North Sea exploration  activity in 1998 also included  participation in
both the United  Kingdom and Danish  North Sea license  rounds.  Kerr-McGee  was
awarded four blocks in the 18th United  Kingdom  round,  totaling  approximately
43,000  net  acres,  and  two  blocks  in  the  fifth  Danish  round,   totaling
approximately 35,500 net acres. Kerr-McGee is the operator for these new blocks.

         Following is a summary of the company's key  developments  in the North
Sea:

         Gryphon field, block 9/18b (46.5%): Kerr-McGee operates this field, and
as a result of the Gulf Canada  transaction,  the company's  interest  increased
from  25% to  46.5%.  Gryphon  was the  first  field in the  North  Sea to use a
permanently moored floating production, storage and offloading (FPSO) vessel. In
1998, the field production rate averaged more than 22,200 barrels of oil per day
and  contributed  more  than  15% of  the  company's  total  net  worldwide  oil
production.

         The Gryphon  Asset Team  successfully  expanded  operations  into areas
adjacent to Gryphon.  Kerr-McGee  was  awarded  block 9/24a in the 18th  license
round  and  reached  an   agreement  to  acquire   equity  in  block  9/23a.   A
new-technology  3D ocean bottom cable seismic survey is planned for 1999,  which
will cover the field and nearby prospective areas.

         Janice field,  block 30/17a  (50.9%):  Modifications  to the Janice "A"
floating  production  unit were  completed,  and the vessel was  inaugurated  in
October  1998.  First  oil from  this  Kerr-McGee-operated  field  commenced  in
February 1999, with peak daily  production  expected to exceed 55,000 barrels of
oil.

         Ross  field,  blocks  13/28a,  13/29a and 13/28c  (14.5%):  Development
drilling and  construction of the FPSO vessel  continued in 1998. First oil from
this new field acquired in the GCRL transaction is expected in 1999 with initial
production estimated at 40,000 barrels of oil per day.

         Brae area,  blocks 16/3a,  16/7a (8%) and 16/3b (5%):  Production  from
the six fields in the Brae area  contributed  more than 11% of Kerr-McGee's  net
worldwide oil production.

         Wytch Farm field (7.4%): Wytch Farm is the largest onshore oil field in
Europe and this  interest was acquired in the GCRL  transaction.  Located on the
southern coast of Dorset, England, production is achieved through extended-reach
horizontal  wells. In 1998, the field averaged nearly 100,000 barrels of oil per
day.

Other International

         In 1998, Kerr-McGee continued its exploration and production efforts by
strategically  expanding  into  various  international  areas.  Significant  new
reserves  were added in  Indonesia,  new  acreage was  acquired in Thailand  and
Gabon, and a strategic alliance was formed in Yemen.

A summary of key developments follows:

Indonesia:

         Jabung block (30%), Sumatra:  Discovered in 1995, this 1.7 million-acre
block  consists  of five  proven  oil  and gas  fields.  An  integrated  plan of
development is being prepared for submission to the Indonesian government, which
will  include the existing  facilities  servicing  the North  Geragai and Makmur
fields.  Completion  of gas  marketing  negotiations  is  expected  in 1999 with
initial deliveries planned for 2001.

         Combined  production from the Makmur field,  which began  production in
January 1998,  and the North  Geragai field  averaged more than 9,700 barrels of
oil per day. After completion of additional  horizontal  drilling and well work,
production in 1999 from these two fields is expected to average more than 11,500
barrels of oil per day.

         Appraisal  work  continued  on the  Northeast  Betara and North  Betara
fields.  The Gemah oil and gas field was  discovered  in late 1998.  Delineation
continues with oil production expected in 2000.

         Several new exploratory  prospects are under  consideration for Jabung.
Drilling plans will be made in 1999.

China:

         Liuhua 11-1 field  (24.5%),  South China Sea:  This field was developed
entirely with horizontal wells. Production averaged nearly 33,000 barrels of oil
per day in 1998.

         Block 04/36 (45%), Bohai Bay: Kerr-McGee is the operator of this block.
A 3D seismic survey was completed in 1998, and a comprehensive evaluation of the
development  potential  of the area has been  completed.  Meetings  with partner
groups are scheduled for early 1999 to evaluate  technical data and  development
options.

Thailand:

         Block W7/38  (42.5%),  Andaman  Sea:  Kerr-McGee  was awarded  this 4.9
million-acre block in March 1998 and is the operator.  A reconnaissance  seismic
survey was acquired and interpreted in 1998, and additional seismic data will be
acquired  in early  1999 to further  delineate  prospective  areas.  Exploration
drilling is planned for 2000.

Gabon:

         In November 1998, the company  acquired a 14% interest in two adjoining
exploration blocks located offshore along the southern coast of Gabon. The Anton
Marin and Astrid Marin blocks  total 3.3 million  acres in water depths  ranging
from 3,000 feet to more than 9,000 feet.  A 3D seismic  program is  scheduled to
begin in 1999, followed by exploration drilling in 2000.

Yemen:

         In 1998,  Kerr-McGee entered into a partnership with a company that has
significant  existing  infrastructure in Yemen. The agreement includes blocks 50
(47.5%) and 51 (43.8%),  which cover nearly 10 million acres.  Interpretation of
seismic data is ongoing, and exploratory drilling is anticipated in 2001.

Brazil:

         Kerr-McGee  and  partners  began  negotiations  in 1998 with  Brazilian
authorities for Block BS-1 (40%),  which covers 2.3 million acres and is located
in water depths ranging from more than 200 feet to 5,000 feet.  Kerr-McGee  will
be  the  operator.   The  company  expects   completion  of  final   contractual
negotiations in 1999.


                                    CHEMICALS

         Kerr-McGee's   chemical   operations   produce  and  market   inorganic
industrial and specialty  chemicals,  heavy minerals and forest products through
its  subsidiaries,  Kerr-McGee  Chemical LLC, KMCC Western  Australia Pty. Ltd.,
Kerr-McGee  Chemical  GmbH,  and  Kerr-McGee  Pigments  Limited.  Many of  these
products are processed using proprietary technology developed by the company.

         Industrial  chemicals  include  titanium  dioxide  pigment,   synthetic
rutile,  manganese products and sodium chlorate.  Specialty  chemicals are boron
trichloride and elemental boron. Heavy minerals produced are ilmenite, synthetic
and natural  rutile,  zircon and leucoxene.  Forest  products  operations  treat
railroad  crossties  and  other  hardwood  products  and  provide  wood-treating
services.

Pigment

         The company's  primary  chemical  product is titanium  dioxide pigment,
which is produced at four titanium  dioxide  (TiO2) plants in the United States,
Australia,  Germany  and  Belgium.  The  plants in  Hamilton,  Mississippi,  and
Kwinana,  Western  Australia,  manufacture TiO2 using the company's  proprietary
chloride-process  technology.  The plants in  Uerdingen,  Germany,  and Antwerp,
Belgium, produce TiO2 using the sulfate process.

         The company's titanium dioxide pigment plant at Hamilton,  Mississippi,
has a  production  capacity of 150,000  metric tons per year.  An  expansion  is
expected to be completed in the third  quarter of 1999,  which will increase the
Hamilton plant's  production  capacity to 178,000 metric tons. The feedstock for
the  Hamilton  plant is  synthetic  rutile from the  company's  plant at Mobile,
Alabama. The annual production capacity at Mobile is 200,000 metric tons.

         On March 31, 1998,  the company  acquired an 80% interest in Bayer AG's
(Bayer)  European  titanium  dioxide  pigment  business,   including  plants  at
Uerdingen,  Germany,  and Antwerp,  Belgium. The Uerdingen plant has capacity of
100,000 metric tons per year, and the Antwerp  plant's annual capacity is 30,000
metric tons.

         The  company  also owns a 25% equity  interest  in a  titanium  dioxide
pigment  plant  in  Yanbu,  Saudi  Arabia.  The  plant  utilizes  the  company's
proprietary chloride process in its manufacturing process.

         The company  owns a 50% interest in a joint  venture  that  operates an
integrated  titanium dioxide project located within 120 miles of Perth,  Western
Australia. The project consists of a heavy-minerals mine and mill and facilities
for production of synthetic rutile and TiO2.

         Heavy minerals are mined from 20,700 acres that are leased by the joint
venture.  The  company's  50% interest in the  property's  remaining  proved and
probable  reserves  represents 151 million metric tons of sand  containing  3.7%
heavy minerals, or heavy minerals in place totaling 5.6 million metric tons. The
valuable  heavy  minerals  are  composed of 4.4% rutile,  61.9%  ilmenite,  3.4%
leucoxene and 11.1% zircon, with the remaining 19.2% of heavy minerals presently
having no value.

         The heavy  minerals are  processed  at the 507,000  metric-ton-per-year
separation mill. The recovered ilmenite is processed into synthetic rutile at an
adjoining synthetic rutile facility, which has a capacity of 195,000 metric tons
per year. Production from the synthetic rutile plant serves as feedstock for the
pigment plants in Australia and Saudi Arabia. The annual production  capacity of
the pigment plants in Kwinana,  Western  Australia,  and Yanbu, Saudi Arabia, in
which the  company  owns  interest of 50% and 25%,  respectively,  is 83,000 and
67,000 metric tons, respectively.

         Information regarding  heavy-mineral  reserves,  production and average
prices  for the three  years  ended  December  31,  1998,  is  presented  in the
following  table.  Mineral  reserves  in this table  represent  those  estimated
quantities  of  proved  and  probable  ore  that,  under  presently  anticipated
conditions,  may be profitably  recovered  and  processed for the  extraction of
their mineral content. Future production of these resources is dependent on many
factors, including market conditions and government regulations.

Electrolytic Products

         Facilities  at the  Hamilton,  Mississippi,  complex  include  a sodium
chlorate plant with a production  capacity of 130,000 metric tons per year and a
manganese metal plant that has an annual capacity of 11,000 metric tons.

         The  Henderson,  Nevada,  facilities  include  electrolytic  cells  and
processing  equipment for the  manufacture of manganese  dioxide and a specialty
boron products plant. Annual production capacity for each product is as follows:
manganese dioxide - 26,500 metric tons; boron  trichloride - 340,000  kilograms;
and elemental boron - 36,000 kilograms.

         In March 1998, Kerr-McGee sold its ammonium perchlorate business.

Forest Products

         The  principal  forest  product is treated  railroad  crossties.  Other
products  include  crossing  materials,  bridge timbers and utility  poles.  The
company's six operating  wood-preserving plants are located along major railways
in Madison, Illinois; Indianapolis, Indiana; Columbus, Mississippi; Springfield,
Missouri; The Dalles, Oregon; and Texarkana, Texas.

Marketing

         Titanium  dioxide pigment is the world's  preferred white opacifier and
is used  primarily  in  coatings,  plastics and paper.  The  company's  plant at
Hamilton,  Mississippi,  primarily  serves  the  Americas.  Most of the  pigment
production from the joint venture in Kwinana,  Western Australia, is sold in the
Far East and Australia. The production from the Uerdingen, Germany, and Antwerp,
Belgium, operations is primarily sold in Europe. The acquisition of the European
plants has increased Kerr-McGee's annual gross titanium dioxide pigment capacity
to about 10% of global  capacity.  World  demand for  pigments  is  expected  to
increase by an average of about 3% per year over the next five years.

         Manganese  dioxide is a major  component  of  alkaline  batteries.  The
company's share of the North American  manganese dioxide market is approximately
one-third.  Demand  is  projected  to grow 5% to 8%  annually  for the next five
years.  The demand is driven by the need for  alkaline  batteries  for  portable
electronic devices.

         Sodium  chlorate  is used  in the  environmentally  preferred  chlorine
dioxide process for bleaching pulp.  Sodium chlorate demand in the United States
is expected to be flat in 1999, then increase  approximately  5% annually in the
near  term as the  pulp and  paper  industry  continues  the  conversion  to the
chlorine dioxide process. The company has about a 7% share of the U.S. market.

         Manganese  metal is used in aluminum and specialty and stainless  steel
alloys.  The primary use of manganese metal is for alloying  aluminum can sheet.
The company supplies  approximately 40% of the U.S. aluminum industry  manganese
requirements.

         Kerr-McGee is the world's largest producer of elemental boron, which is
used primarily in automobile airbags. Kerr-McGee is also the largest producer of
boron trichloride,  which is used to produce boron filament for sports equipment
and   composites   for    high-performance    aircraft,    pharmaceuticals   and
semi-conductors.

         The  company's  share  of the U.S.  railroad  crosstie  market  is 38%.
Domestic  crosstie  demand is  expected  to remain  relatively  flat at about 13
million to 15 million ties per year.


                             DISCONTINUED OPERATIONS

         In early  1998,  the  company  announced  its  intent  to exit the coal
business.  The  sales  of the  coal  assets  were  completed  in July  1998  for
approximately  $600  million.  For  additional   discussion  about  discontinued
operations,  reference  is  made  to  the  "Transactions  in  1998"  section  of
Management's  Discussion and Analysis and Note 22 to the Consolidated  Financial
Statements in the 1998 Annual Report to Stockholders,  which are incorporated by
reference in Items 7 and 8.

                                      OTHER

Research and Development

         The company's  Technical Center in Oklahoma City performs  research and
development  in support of its  existing  businesses  and in the  pursuit of new
products and processes.  These programs  continue to concentrate on improvements
to chemical plant processes and products.

Employees

         On December 31, 1998,  the company had 3,367  employees.  Approximately
600, or 18% of these employees were represented by chemical industry  collective
bargaining agreements in Europe.

Competitive Conditions

         In the petroleum industry,  competition exists from the initial process
of bidding  for  leases to the sale of crude oil and  natural  gas.  Competitive
factors  include  finding  and  developing  petroleum,  producing  crude oil and
natural gas efficiently, transporting the produced crude oil and natural gas and
developing successful marketing strategies.

         The titanium dioxide pigment business is very  competitive.  The number
of  competitors  in the industry has  declined due to recent  consolidations,  a
trend  that is  expected  to  continue  as  companies  owning  chloride  process
technology  acquire  operations  that use the older  sulfate  technology.  It is
expected  that many of these  sulfate  plants will be  converted to the chloride
technology.  Worldwide,  Kerr-McGee  is one of  only  four  companies  that  own
chloride  technology to produce titanium dioxide pigment.  Cost efficiencies and
product  quality are key  competitive  factors in the titanium  dioxide  pigment
business.

         It is not  possible  to  predict  the effect of future  competition  on
Kerr-McGee's operating and financial results.


                GOVERNMENT REGULATIONS AND ENVIRONMENTAL RESERVES

General

         The company is subject to extensive regulation by federal, state, local
and foreign governments. The production and sale of crude oil and natural gas in
the United States are subject to  regulation  by federal and state  authorities,
particularly with respect to allowable rates of production, offshore exploration
and production and  environmental  matters.  Stringent  environmental-protection
laws and  regulations  apply  to  almost  all of the  company's  operations.  In
addition, there are special taxes that apply to the oil and gas industry.

Environmental Matters

         Federal, state and local laws and regulations relating to environmental
protection affect almost all company operations. During 1998, direct capital and
operating  expenditures  related  to  environmental  protection  and  cleanup of
existing  sites  totaled $37  million.  Additional  expenditures  totaling  $105
million were charged to environmental reserves.  While it is extremely difficult
to estimate  the total direct and  indirect  costs to the company of  government
environmental regulations, it is presently estimated that the direct capital and
operating   expenditures   and   expenditures   charged  to  reserves   will  be
approximately  $115 million in both 1999 and 2000.  Some  expenditures to reduce
the  occurrence  of  releases  to  the   environment  may  result  in  increased
efficiency;  however, most of these expenditures produce no significant increase
in production  capacity,  efficiency or revenue.  Operation of pollution-control
equipment installed for these purposes usually entails additional expense.

         Based on present information,  the company believes that it has accrued
and is accruing reasonable reserves for expenditures that may have to be paid in
the future for environmental  matters.  Because of continually changing laws and
regulations,  the nature of the company's  businesses,  negotiations and pending
proceedings, it is not possible to reliably estimate the amount or timing of all
future expenditures relating to environmental  matters. The company provides for
costs related to  environ-mental  contingencies  when a loss is probable and the
amount is reasonably  estimable.  Although management believes adequate reserves
have been provided for all known  environmental  contingencies,  it is possible,
due to the above-noted uncertainties, that additional reserves could be required
in the future.

Item 3.   Legal Proceedings

         The company  continues its efforts to  decommission  a facility in West
Chicago,  Illinois,  which processed  thorium ores and was closed in 1973. For a
discussion of contingencies, including a detailed discussion of the West Chicago
matter,  reference is made to the Environmental  Matters section of Management's
Discussion and Analysis and Note 9 to the Consolidated  Financial  Statements in

     Statement Schedule                                         

To Kerr-McGee Corporation:

         We  have  audited  in  accordance  with  generally   accepted  auditing
standards,   the  consolidated   financial  statements  included  in  Kerr-McGee
Corporation's  1998 Annual Report to  Stockholders  incorporated by reference in
this Form 10-K,  and have issued our report thereon dated February 26, 1999. Our
audit was made for the purpose of forming an opinion on those  statements  taken
as  a  whole.   The  Schedule  of   Valuation   Accounts  and  Reserves  is  the
responsibility  of the  company's  management  and is presented  for purposes of
complying with the Securities and Exchange Commission's rules and is not part of
the basic consolidated financial statements. This schedule has been subjected to
the auditing procedures applied in the audit of the basic consolidated financial
statements  and, in our  opinion,  fairly  states in all  material  respects the
financial  data  required  to be set  forth  therein  in  relation  to the basic
consolidated financial statements taken as a whole.

                              AMENDED AND RESTATED

                          CERTIFICATE OF INCORPORATION

                                       OF

                             KERR-McGEE CORPORATION



         FIRST:            The name of the corporation is:

                             KERR-McGEE CORPORATION

         SECOND:  The  registered  office  of  the  corporation in  the State of
Delaware is located at No. 1209 Orange Street, in the City of Wilmington, County
of New Castle.  The name and address of its resident  agent is The  Corporation
Trust Company,  No. 1209 Orange Street, Wilmington, Delaware 19801.

         THIRD:   The purpose of the corporation  is to engage in any lawful act
or   activity  for  which  corporations  may  be  organized  under  the  General
Corporation Law of the State of Delaware.

         FOURTH:  (1) The total  number of shares of all  classes of stock which
the  corporation  shall have the  authority  to issue is  340,000,000,  of which
40,000,000  shares shall be preferred stock,  without par value, and 300,000,000
shall be common stock of the par value of $1.00 per share.

         Each holder of common stock, as such, shall be entitled to one vote for
each share of common stock held of record by such holder on all matters on which
stockholders generally are entitled to vote; provided,  however, that, except as
otherwise  required  by law,  holders  of common  stock,  as such,  shall not be
entitled  to  vote  on  any  amendment  to  this  certificate  of  incorporation
(including any certificate of  designations  relating to any series of preferred
stock) that  relates  solely to the terms of one or more  outstanding  series of
preferred  stock if the holders of such  affected  series are  entitled,  either
separately  or together  with the holders of one or more other such  series,  to
vote  thereon  pursuant to this  certificate  of  incorporation  (including  any
certificate  of  designations  relating  to any  series of  preferred  stock) or
pursuant to the General Corporation Law of the State of Delaware.

                  (2) The preferred stock may be issued from time to time in one
or more  series.  The  resolution  or  resolutions  of the  Board  of  Directors
providing for the issue of shares of a particular  series shall fix,  subject to
applicable laws and provisions of this certificate of incorporation,  the voting
power, designation,  preferences and relative, participating,  optional or other
special rights, and qualifications, limitations or restrictions of the shares of
such series. The authority of the Board of Directors with respect to each series
shall include, but not be limited to, determination of the following:

                  i)       the   number  of  shares  constituting  such  series,
                           including  the authority to increase or decrease such
                           number,  and  the  distinctive  designation  of  such
                           series;

                  ii)      the  rate of  dividends  payable  on  shares  of such
                           series,  the dates on which such  dividends  shall be
                           paid, and whether such dividends  shall be cumulative
                           or noncumulative;

                  iii)     the full or limited  voting  power,  if any, for such
                           series and the terms and conditions  under which such
                           voting power may be exercised;

                  iv)      the  right,  if any,  of the  corporation  to  redeem
                           shares of such series and the terms and conditions of
                           such redemption;

                  v)       the obligations, if any, of the corporation to retire
                           shares of such  series  pursuant to a  retirement  or
                           sinking fund of a similar nature or otherwise and the
                           terms and conditions of such obligation;

                  vi)      the  terms and  conditions,  if any,  upon  which the
                           shares  of such  series  shall  be  convertible  into
                           shares  of  stock  of  any  other   class  or  series
                           including  the  conversion   rate  and  the  term  of
                           adjustment thereof, if any;

                  vii)     the  amount  which the  holders of the shares of such
                           series  shall be  entitled  to  receive  in case of a
                           liquidation,   dissolution   or  winding  up  of  the
                           corporation;

                  viii)    the relative priority of the shares of such series to
                           shares of other  classes  or series  with  respect to
                           dividends   or  upon  the   dissolution   of  or  the
                           distribution of assets of the corporation; and

                  ix)      and other rights and qualifications,  preferences and
                           limitations  or  restrictions  of the  shares of such
                           series;

                           so far as not  inconsistent  with the  provisions  of
                           this  certificate  of  incorporation  and to the full
                           extent now or hereafter  permitted by the laws of the
                           State of Delaware.

         (3) Except as otherwise  provided in this  paragraph  (3), no direct or
indirect  purchase  by the  corporation  from  any  Interested  Stockholder  (as
hereinafter  defined) of shares of common stock of the corporation  beneficially
owned by such  Interested  Stockholder for less than two years prior to the date
of such  purchase  shall be made at a per share  price in excess of Fair  Market
Value (as hereinafter defined) at the time of such purchase unless such purchase
is  approved by the  affirmative  vote of not less than a majority of the Voting
Stock (as defined in Article THIRTEENTH) held by Disinterested  Stockholders (as
hereinafter defined).

         The  provisions of this  paragraph (3) shall not apply to (i) any offer
to  purchase  made  by the  corporation  which  is made on the  same  terms  and
conditions of the holders of all shares of common stock of the  corporation,  or
(ii) any open market  purchases by the corporation of shares of its common stock
at prevailing market prices.

         The provisions of this  paragraph (3) shall not be amended  without the
affirmative vote of (a) not less than a majority of the Voting Stock entitled to
vote  thereon and (b) not less than a majority of the Voting  Stock  entitled to
vote thereon held by Disinterested Stockholders.

         For  purposes  of  this  paragraph   (3);  I)  the  terms   "Interested
Stockholder"  shall have the meaning of "Related  Person" set forth in paragraph
(B)(3) of Article THIRTEENTH except that the percent of Voting Stock referred to
in clauses (a) and (b) of such definition shall be five percent (5%) rather than
ten percent (10%);  (ii) the term "Fair Market Value" shall have the meaning set
forth in paragraph (B)(9) of Article  THIRTEENTH except that "Fair Market Value"
shall mean the highest sale price or bid quotation  during the  five-trading day
period  preceding  the date of the  purchase  of the stock;  and (iii) the terms
"Disinterested  Stockholders"  means those holders of the Voting Stock,  none of
which is an Interested Stockholder.

         (4)      Series B Preferred Stock

                  Section 1. Designation and Amount. There shall be designated a
series of preferred  stock as "Series B Junior  Participating  Preferred  Stock"
(the  "Series B  Preferred  Stock")  and the number of shares  constituting  the
Series B  Preferred  Stock  shall be  1,000,000.  Such  number of shares  may be
increased or decreased by resolution of the Board of Directors;  provided,  that
no decrease  shall reduce the number of shares of Series B Preferred  Stock to a
number less than the number of shares then outstanding plus the number of shares
reserved  for  issuance  upon the  exercise of  outstanding  options,  rights or
warrants or upon the  conversion  of any  outstanding  securities  issued by the
corporation convertible into Series B Preferred Stock.

                  Section 2.        Dividends and Distributions.

                  (A)  Subject to the rights of the holders of any shares of any
series of preferred  stock of the corporation  (the  "Preferred  Stock") (or any
similar stock)  ranking prior and superior to the Series B Preferred  Stock with
respect to  dividends,  the  holders of shares of Series B Preferred  Stock,  in
preference  to the  holders  of common  stock of the  corporation  (the  "Common
Stock") and of any other stock of the corporation ranking junior to the Series B
Preferred Stock,  shall be entitled to receive,  when, as and if declared by the
Board of Directors  out of funds legally  available  for the purpose,  quarterly
dividends payable in cash on the last day of January,  April,  July, and October
in each year (each such date being  referred  to herein as a  "Dividend  Payment
Date"),  commencing on the first Dividend  Payment Date after the first issuance
of a share or fraction of a share of Series B Preferred  Stock, in an amount per
share  (rounded  to the  nearest  cent)  equal to the  greater  of (a) $1 or (b)
subject to the provision for  adjustment  hereinafter  set forth,  100 times the
aggregate  per share amount of all cash  dividends,  and 100 times the aggregate
per  share  amount  (payable  in  kind)  of  all  non-cash  dividends  or  other
distributions other than a dividend payable in shares of Common Stock,  declared
on the Common Stock since the immediately  preceding  Dividend  Payment Date or,
with respect to the first Dividend Payment Date, since the first issuance of any
share or  fraction  of a share of  Series B  Preferred  Stock.  In the event the
corporation  shall at any time after July 9, 1996 declare or pay any dividend on
the Common Stock payable in shares of Common Stock,  or effect a subdivision  or
combination  or  consolidation  of the  outstanding  shares of Common  Stock (by
reclassification  or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common  Stock,  then in each
such case the amount to which holders of shares of Series B Preferred Stock were
entitled  immediately  prior to such event  under  clause  (b) of the  preceding
sentence  shall be  adjusted  by  multiplying  such  amount by a  fraction,  the
numerator  of  which  is the  number  of  shares  of  Common  Stock  outstanding
immediately  after  such  event and the  denominator  of which is the  number of
shares of Common Stock that were outstanding immediately prior to such event.

                  (B) The  corporation  shall declare a dividend or distribution
on the Series B Preferred  Stock as provided in  paragraph  (A) of this  Section
immediately  after it declares a dividend or  distribution  on the Common  Stock
(other than a dividend payable in shares of Common Stock); provided that, in the
event no dividend or  distribution  shall have been declared on the Common Stock
during the period  between any  Dividend  Payment  Date and the next  subsequent
Dividend  Payment  Date,  a dividend  of $1 per share on the Series B  Preferred
Stock  shall  nevertheless  be  payable,  when,  as and  if  declared,  on  such
subsequent Dividend Payment Date.

                  (C) Dividends shall begin to accrue and be cumulative, whether
or not earned or declared,  on  outstanding  shares of Series B Preferred  Stock
from the Dividend  Payment Date next preceding the date of issue of such shares,
unless  the date of issue of such  shares  is prior to the  record  date for the
first Dividend  Payment Date, in which case dividends on such shares shall begin
to accrue from the date of issue of such shares,  or unless the date of issue is
a Dividend Payment Date or is a date after the record date for the determination
of holders of shares of Series B Preferred Stock entitled to receive a quarterly
dividend and before such  Dividend  Payment Date, in either of which events such
dividends  shall begin to accrue and be cumulative  from such  Dividend  Payment
Date.  Accrued but unpaid  dividends shall not bear interest.  Dividends paid on
the shares of Series B Preferred  Stock in an amount less than the total  amount
of such  dividends  at the time  accrued  and  payable on such  shares  shall be
allocated pro rata on a  share-by-share  basis among all such shares at the time
outstanding.  The Board of Directors may fix a record date for the determination
of holders of shares of Series B Preferred  Stock entitled to receive payment of
a dividend or distribution declared thereon, which record date shall be not more
than 60 days prior to the date fixed for the payment thereof.

                  Section 3.        Voting Rights.  The holders of shares of 
Series B Preferred  Stock shall have the following  voting rights:

                           (A)   Subject  to  the   provision   for   adjustment
         hereinafter  set  forth  and  except  as  otherwise  provided  in  this
         certificate of incorporation or required by law, each share of Series B
         Preferred  Stock shall  entitle the holder  thereof to 100 votes on all
         matters upon which the holders of the Common  Stock of the  corporation
         are entitled to vote.  In the event the  corporation  shall at any time
         after July 9, 1996  declare  or pay any  dividend  on the Common  Stock
         payable  in  shares  of  Common  Stock,  or  effect  a  subdivision  or
         combination or consolidation of the outstanding  shares of Common Stock
         (by  reclassification  or  otherwise  than by payment of a dividend  in
         shares of Common  Stock)  into a greater or lesser  number of shares of
         Common  Stock,  then in each such case the number of votes per share to
         which  holders  of shares of Series B  Preferred  Stock  were  entitled
         immediately  prior to such event shall be adjusted by multiplying  such
         number by a fraction, the numerator of which is the number of shares of
         Common  Stock   outstanding   immediately  after  such  event  and  the
         denominator  of which is the number of shares of Common Stock that were
         outstanding immediately prior to such event.

                  (B) Except as otherwise  provided herein,  in this certificate
         of incorporation or in any other certificate of designations creating a
         series of Preferred Stock or any similar stock, and except as otherwise
         required by law, the holders of shares of Series B Preferred  Stock and
         the holders of shares of Common  Stock and any other  capital  stock of
         the corporation having general voting rights shall vote together as one
         class  on all  matters  submitted  to a  vote  of  stockholders  of the
         corporation.

                  (C) Except as set forth  herein,  or as otherwise  provided by
         law,  holders of Series B Preferred  Stock shall have no special voting
         rights and their  consent  shall not be required  (except to the extent
         they are  entitled  to vote with  holders of Common  Stock as set forth
         herein) for taking any corporate action.

                  Section 4.        Certain Restrictions.

                           (A) Whenever  quarterly  dividends or other dividends
         or distributions payable on the Series B Preferred Stock as provided in
         Section 2 are in arrears,  thereafter  and until all accrued and unpaid
         dividends  and  distributions,  whether or not earned or  declared,  on
         shares of Series B Preferred Stock  outstanding shall have been paid in
         full, the corporation shall not:

                           (i)  declare  or pay  dividends,  or make  any  other
                  distributions,  on any shares of stock  ranking  junior (as to
                  dividends) to the Series B Preferred Stock;

                           (ii)  declare  or pay  dividends,  or make any  other
                  distributions,  on any shares of stock ranking on a parity (as
                  to  dividends)  with the  Series  B  Preferred  Stock,  except
                  dividends paid ratably on the Series B Preferred Stock and all
                  such parity stock on which dividends are payable or in arrears
                  in proportion to the total amounts to which the holders of all
                  such shares are then entitled;

                           (iii)  redeem or  purchase or  otherwise  acquire for
                  consideration shares of any stock ranking junior (either as to
                  dividends or upon  liquidation,  dissolution or winding up) to
                  the Series B Preferred  Stock,  provided that the  corporation
                  may at any time redeem,  purchase or otherwise  acquire shares
                  of any such junior  stock in exchange  for shares of any stock
                  of the  corporation  ranking  junior (as to dividends and upon
                  dissolution,  liquidation  or  winding  up)  to the  Series  B
                  Preferred Stock or rights, warrants or options to acquire such
                  junior stock;

                           (iv)  redeem or  purchase  or  otherwise  acquire for
                  consideration  any shares of Series B Preferred  Stock, or any
                  shares of stock ranking on a parity (either as to dividends or
                  upon liquidation, dissolution or winding up) with the Series B
                  Preferred  Stock,  except in accordance  with a purchase offer
                  made in writing or by publication  (as determined by the Board
                  of Directors) to all holders of such shares upon such terms as
                  the Board of Directors,  after consideration of the respective
                  annual   dividend   rates  and  other   relative   rights  and
                  preferences  of  the  respective  series  and  classes,  shall
                  determine  in good  faith  will  result in fair and  equitable
                  treatment among the respective series or classes.

                  (B) The  corporation  shall not permit any  subsidiary  of the
         corporation  to purchase or  otherwise  acquire for  consideration  any
         shares of stock of the corporation  unless the corporation could, under
         paragraph  (A) of this Section 4,  purchase or  otherwise  acquire such
         shares at such time and in such manner.

                  Section 5. Reacquired Shares. Any shares of Series B Preferred
Stock  purchased  or  otherwise  acquired  by  the  corporation  in  any  manner
whatsoever  shall be  retired  and  cancelled  promptly  after  the  acquisition
thereof.  All such shares  shall upon their  retirement  become  authorized  but
unissued  shares of Preferred  Stock and may be reissued as part of a new series
of Preferred  Stock to be created by resolution or  resolutions  of the Board of
Directors,  subject to any  conditions  and  restrictions  on issuance set forth
herein.

                  Section 6.  Liquidation,  Dissolution  or Winding Up. Upon any
liquidation, dissolution or winding up of the corporation, no distribution shall
be made (A) to the  holders of the Common  Stock or of shares of any other stock
of the corporation ranking junior, upon liquidation,  dissolution or winding up,
to the Series B Preferred Stock unless,  prior thereto, the holders of shares of
Series B Preferred  Stock  shall have  received  $100 per share,  plus an amount
equal to accrued and unpaid dividends and distributions thereon,  whether or not
earned or declared,  to the date of such  payment,  provided that the holders of
shares of Series B Preferred  Stock  shall be  entitled to receive an  aggregate
amount per share, subject to the provision for adjustment hereinafter set forth,
equal to 100 times the aggregate  amount to be distributed  per share to holders
of shares of Common Stock, or (B) to the holders of shares of stock ranking on a
parity upon  liquidation,  dissolution or winding up with the Series B Preferred
Stock, except distributions made ratably on the Series B Preferred Stock and all
such parity stock in proportion to the total amounts to which the holders of all
such shares are entitled upon such  liquidation,  dissolution  or winding up. In
the event,  however,  that there are not sufficient  assets  available to permit
payment  in full of the  Series B  liquidation  preference  and the  liquidation
preferences of all other classes and series of stock of the corporation, if any,
that rank on a parity with the Series B Preferred Stock in respect thereof, then
the assets available for such distribution  shall be distributed  ratably to the
holders of the Series B Preferred Stock and the holders of such parity shares in
the proportion to their  respective  liquidation  preferences.  In the event the
corporation  shall at any time after July 9, 1996 declare or pay any dividend on
the Common Stock payable in shares of Common Stock,  or effect a subdivision  or
combination  or  consolidation  of the  outstanding  shares of Common  Stock (by
reclassification  or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common  Stock,  then in each
such case the aggregate  amount to which holders of shares of Series B Preferred
Stock were entitled  immediately prior to such event under the proviso in clause
(A) of the preceding  sentence shall be adjusted by multiplying such amount by a
fraction  the  numerator  of which is the  number  of  shares  of  Common  Stock
outstanding  immediately  after such event and the  denominator  of which is the
number of shares of Common Stock that were outstanding immediately prior to such
event.

                  Section 7. Consolidation, Merger, etc. In case the corporation
shall enter into any consolidation,  merger, combination or other transaction in
which the shares of Common Stock are  converted  into,  exchanged for or changed
into other stock or securities, cash and/or any other property, then in any such
case each share of Series B Preferred  Stock shall at the same time be similarly
converted  into,  exchanged for or changed into an amount per share  (subject to
the  provision  for  adjustment  hereinafter  set forth)  equal to 100 times the
aggregate amount of stock,  securities,  cash and/or any other property (payable
in kind), as the case may be, into which or for which each share of Common Stock
is converted,  exchanged or converted. In the event the corporation shall at any
time after July 9, 1996 declare or pay any dividend on the Common Stock  payable
in  shares  of  Common  Stock,   or  effect  a  subdivision  or  combination  or
consolidation of the outstanding shares of Common Stock (by  reclassification or
otherwise  than by  payment  of a  dividend  in shares of Common  Stock)  into a
greater or lesser number of shares of Common  Stock,  then in each such case the
amount set forth in the  preceding  sentence  with  respect  to the  conversion,
exchange  or change of shares of Series B  Preferred  Stock shall be adjusted by
multiplying  such amount by a fraction,  the numerator of which is the number of
shares  of  Common  Stock  outstanding  immediately  after  such  event  and the
denominator  of  which is the  number  of  shares  of  Common  Stock  that  were
outstanding immediately prior to such event.

                  Section 8.  No Redemption.  The  shares  of Series B Preferred
Stock shall not be redeemable from any holder.

                  Section 9. Rank. The Series B Preferred Stock shall rank, with
respect  to the  payment  of  dividends  and the  distribution  of  assets  upon
liquidation,  dissolution or winding up of the corporation,  junior to all other
series of Preferred Stock and senior to the Common Stock.

                  Section  10.  Amendment.  If any  proposed  amendment  to this
certificate  of  incorporation   would  alter,  change  or  repeal  any  of  the
preferences,  powers or special rights given to the Series B Preferred  Stock so
as to affect the Series B  Preferred  Stock  adversely,  then the holders of the
Series B Preferred  Stock shall be entitled to vote  separately  as a class upon
such amendment, and the affirmative vote of two-thirds of the outstanding shares
of the  Series  B  Preferred  Stock,  voting  separately  as a  class,  shall be
necessary  for the  adoption  thereof,  in addition to such other vote as may be
required by the General Corporation Law of the State of Delaware.

                  Section 11. Fractional Shares. Series B Preferred Stock may be
issued in fractions of a share that shall  entitle the holder,  in proportion to
such holder's  fractional shares, to exercise voting rights,  receive dividends,
participate  in  distributions  and to have the  benefit of all other  rights of
holders of Series B Preferred Stock.

         (5) Preemptive  Rights.  Neither the holders of preferred stock nor the
holders of common stock shall have any preemptive  rights,  and the  corporation
shall have the right to issue and sell to any  person or  persons  any shares of
its capital stock or any option rights or any  securities  having  conversion or
option rights,  without first offering such shares,  rights or securities to any
holders of preferred stock or common stock.

         FIFTH: (1) The business and affairs of the corporation shall be managed
by a Board of  Directors.  The number of  directors  shall be fixed from time to
time by resolution  adopted by affirmative  vote of the majority of the Board of
Directors, but shall not be fixed at a number less than three.

                  The directors  shall be  classified,  with respect to the time
for which they  severally hold office,  into three  classes,  as nearly equal in
number  as  possible,  with the term of the  first  class to  expire at the 1999
annual  meeting of the  stockholders,  the term of office of the second class to
expire at the 2000 annual meeting of the stockholders, and the term of office of
the third class to expire at the 2001 annual meeting of the  stockholders,  with
the members of each class to hold office until their  successors are elected and
qualified.  At  each  succeeding  annual  meeting  of  the  stockholders  of the
corporation,  the successors to the class of directors whose term expires at the
meeting  shall be  elected  to hold  office  for a term  expiring  st the annual
meeting of the  stockholders  held in the third year following the year of their
election.

                  Newly created directorships resulting from any increase in the
number of directors and any vacancies on the Board of Directors  resulting  from
death, resignation,  disqualification, removal or other cause shall be filled by
the  affirmative  vote of a majority of the remaining  directors then in office,
even though less than a quorum of the Board of Directors.  Any director  elected
in accordance with the preceding sentence shall hold office for the remainder of
the full  term of the  class of  directors  in which  the new  directorship  was
created or the vacancy occurred until such director's  successor shall have been
elected and qualified.  No decrease in the number of directors  constituting the
Board of Directors shall shorten the term of any incumbent director.

                  Directors may be removed only for cause,  and then only by the
affirmative  vote of at least 75  percent  in voting  power of all shares of the
corporation entitled to vote generally in the election of directors, voting as a
single class.

         (2) Notwithstanding  the foregoing,  whenever the holders of any one or
more series of preferred stock issued by the  corporation  shall have the right,
voting  separately  as a series or  separately  as a class with one or more such
other  series,   to  elect   directors  at  an  annual  or  special  meeting  of
stockholders,  the election, term of office,  removal,  filling of vacancies and
other  features  of such  directorships  shall be  governed by the terms of this
certificate of incorporation (including any certificate of designations relating
to any series of preferred  stock)  applicable  thereto,  and such  directors so
elected shall not be divided into classes  pursuant to this Article FIFTH unless
expressly provided by such terms.

         SIXTH:  The Board of  Directors  shall be  authorized  to make,  amend,
alter, change, add to or repeal the By-Laws of the corporation in any manner not
inconsistent with the laws of the State of Delaware, subject to the power of the
stockholders to amend,  alter,  change, add to or repeal the By-Laws made by the
Board of Directors.  Notwithstanding  anything  contained in this certificate of
incorporation  to the contrary,  the affirmative vote of the holders of at least
75 percent in voting power of all the shares of the corporation entitled to vote
generally in the election of directors, voting together as a single class, shall
be  required  in order  for the  stockholders  to  alter,  amend or  repeal  any
provision of the By-Laws which is to the same effect as Article  FIFTH,  Article
SIXTH,  and Article  FOURTEENTH of this certificate of incorporation or to adopt
any provision inconsistent therewith.

         SEVENTH: (1) (a) The corporation shall, to the full extent permitted by
the Laws of the State of  Delaware as then in effect or, if less  stringent,  in
effect on December 31, 1985 ("Delaware Law"), and as more fully described in the
By-Laws, indemnify any person (the "Indemnitee") made or threatened to be made a
party to any  threatened,  pending  or  completed  action,  suit or  proceeding,
whether civil,  criminal,  administrative or investigative and whether or not by
or in the right of the corporation, by reason of the fact that the Indemnitee is
or was a director,  officer or employee of the  corporation or is or was serving
at the request of the  corporation as a director,  officer,  employee,  trustee,
partner,  or other  agent of any  other  enterprise  or legal  person  (any such
action, suit or proceeding being herein referred to as a "Legal Action") against
all expenses (including attorneys' fees),  judgments,  fines and amounts paid in
settlement actually and reasonably incurred by the Indemnitee in connection with
such  Legal  Action  or its  investigation,  defense  or appeal  (herein  called
"Indemnified  Expenses"),  if the  Indemnitee  has met the  standard  of conduct
necessary  under  Delaware  Law  to  permit  such  indemnification.   Rights  to
indemnification  shall extend to the heirs,  beneficiaries,  administrators  and
executors of any deceased Indemnitee.

                  For  purposes  of  this  Section,   reference  to  "any  other
enterprise or legal person" shall include employee benefit plans;  references to
"fines" shall  include any excise taxes  assessed on a person with respect to an

of the  corporation  which  imposes  duties on, or  involves  services  by, such
director,  officer, employee, or agent with respect to an employee benefit plan,
its participants, or beneficiaries.

                  (b) The Indemnified  Expenses shall be paid by the corporation
in advance as shall be appropriate to permit  Indemnitee to defray such expenses
currently as incurred,  provided  the  Indemnitee  agrees in writing that in the
event it shall  ultimately be determined as provided  hereunder that  Indemnitee
was not entitled to be indemnified,  then Indemnitee shall promptly repay to the
corporation such amounts so paid.

                  (c) Any  amendment,  repeal or  modification  of this  Article
SEVENTH, the corporation's  By-Laws or any applicable provision of Delaware Law,
or any other  instrument,  which  eliminates or diminishes  the  indemnification
rights  provided for in this Article  SEVENTH shall be ineffective as against an
Indemnitee  with respect to any Legal  Action  based upon  actions  taken or not
taken  by  the  Indemnitee  prior  to  such  repeal  or  the  adoption  of  such
modification or amendment.  The provisions of this Article SEVENTH,  Section (1)
shall be applicable  to all Legal  Actions made or commenced  after the adoption
hereof,  whether arising from acts or omissions to act occurring before or after
its  adoption.  The  provisions  of this Article  SEVENTH,  Section (1) shall be
deemed to be a contract between the corporation and each director or officer who
serves in such capacity at any time while this Article SEVENTH,  Section (1) and
the relevant provisions of Delaware Law and other applicable law, if any, are in
effect. If any provision of this Article SEVENTH,  Section (1) shall be found to
be  invalid or limited in  application  by reason of any law or  regulation,  it
shall not affect the validity of the remaining  provisions hereof. The rights of
indemnification  provided in this Article SEVENTH,  Section (1) shall neither be
exclusive  of, nor be deemed in  limitation  of, any rights to which an officer,
director,  employee or agent may otherwise be entitled or permitted by contract,
this  certificate  of  incorporation,  vote  of  stockholders  or  directors  or
otherwise,  or as a matter of law, both as to actions in such person's  official
capacity and actions in any other capacity  while holding such office,  it being
the  policy of the  corporation  that  indemnification  of any  person  whom the
corporation is obligated to indemnify pursuant to subsection (a) of this Article
SEVENTH, Section (1) shall be made to the fullest extent permitted by law.

                  (d) The  corporation  may purchase  and maintain  insurance on
behalf of any  person  described  in  subsection  (a) of this  Article  SEVENTH,
Section (1) against any liability  asserted against such person,  whether or not
the  corporation  would have the power to  indemnify  such person  against  such
liability  under  the  provisions  of  this  Article  SEVENTH,  Section  (1)  or
otherwise.

         (2) To the full extent permitted by the General  Corporation Law of the
State of Delaware as the same exists or may hereafter be amended,  a director of
the corporation  shall not be liable to the corporation or its  stockholders for
monetary  damages  for  breach  of  fiduciary  duty as a  director.  No  repeal,
amendment or  modification  of this Article,  whether direct or indirect,  shall
eliminate or reduce its effect with respect to any act or omission of a director
of the corporation occurring prior to such repeal, amendment or modification.

corporation  and  its  creditors  or any  class  of  them  and/or  between  this
corporation  and its  stockholders  or any class of them, any court of equitable

way of this  corporation  or of any  creditor or  stockholder  thereof or on the

stockholders of this corporation, as the case may be, agree to any compromise or
arrangement and to any  reorganization  of this  corporation as a consequence of

                  (1)  Nominations  of  persons  for  election  to the  Board of
Directors of the  Corporation  and the proposal of business to be  considered by
the  stockholders  may be made at an annual meeting of stockholders (a) pursuant
to the  Corporation's  notice of meeting  delivered  pursuant  to  Article  III,
Section 6 of these  By-Laws,  (b) by or at the direction of the Chief  Executive
Officer or the Board of Directors or (c) by any  stockholder of the  Corporation
who is entitled to vote at the meeting,  who complied with the notice procedures
set forth in subparagraphs  (2) and (3) of this paragraph (A) of this By-Law and
who was a  stockholder  of record at the time such  notice is  delivered  to the
Secretary of the Corporation.

                  (2) For  nominations or other business to be properly  brought
before an annual  meeting by a  stockholder  pursuant to clause (c) of paragraph
(A)(1) of this By-Law,  the stockholder must have given timely notice thereof in
writing to the Secretary of the Corporation,  and, in the case of business other
than  nominations,  such other business must be a proper matter for  stockholder
action. To be timely, a stockholder's notice shall be delivered to the Secretary
at the principal executive offices of the Corporation not less than seventy days
nor more than ninety days prior to the first anniversary of the preceding year's
annual meeting; provided, however, that in the event that the date of the annual
meeting is advanced by more than twenty  days,  or delayed by more than  seventy
days, from such anniversary date, notice by the stockholder to be timely must be
so delivered not earlier than the ninetieth day prior to such annual meeting and
not later than the close of business on the later of the seventieth day prior to
such  annual  meeting  or the  tenth  day  following  the  day on  which  public
announcement  of the date of such  meeting  is first  made.  Such  stockholder's
notice  shall set forth (a) as to each person whom the  stockholder  proposes to
nominate for election or re-election as a director all  information  relating to
such person that is required to be  disclosed  in  solicitations  of proxies for
election  of  directors,  or is  otherwise  required,  in each case  pursuant to
Regulation  14A under the  Securities  Exchange  Act of 1934,  as  amended  (the
"Exchange  Act"),  including such person's written consent to being named in the
proxy statement as a nominee and to serving as a director if elected;  (b) as to
any other business that the stockholder  proposes to bring before the meeting, a
brief description of the business desired to be brought before the meeting,  the
reasons for conducting such business at the meeting and any material interest in
such business of such  stockholder  and the beneficial  owner,  if any, on whose
behalf the proposal is made; and (c) as to the stockholder giving the notice and
the beneficial owner, if any, on whose behalf the nomination or proposal is made

stockholder and such beneficial owner.

                  (3)  Notwithstanding   anything  in  the  second  sentence  of
paragraph (A)(2) of this By-Law to the contrary, in the event that the number of
directors  to be  elected  to the  Board  of  Directors  of the  Corporation  is
increased  and there is no public  announcement  naming all of the  nominees for
director or specifying the size of the increased  Board of Directors made by the
Corporation at least eighty days prior to the first anniversary of the preceding
year's annual meeting, a stockholder's notice required by this By-Law shall also
be  considered  timely,  but only with respect to nominees for any new positions
created by such  increase,  if it shall be  delivered  to the  Secretary  at the
principal  executive  offices  of the  Corporation  not later  than the close of
business on the tenth day following the day on which such public announcement is
first made by the Corporation.

                  (B) Special Meetings of Stockholders. Only such business shall
be conducted  at a special  meeting of  stockholders  as shall have been brought
before the meeting pursuant to the  Corporation's  notice of meeting pursuant to
Article III, Section 10 of these By-Laws. Nominations of persons for election to
the Board of Directors may be made at a special meeting of stockholders at which
directors are to be elected pursuant to the Corporation's  notice of meeting (a)
by or at the direction of the Chief Executive  Officer or the Board of Directors
or (b) by any  stockholder  of the  Corporation  who is  entitled to vote at the
meeting,  who complies with the notice  procedures  set forth in this By-Law and
who is a  stockholder  of  record at the time such  notice is  delivered  to the
Secretary  of the  Corporation.  Nominations  of  stockholders  of  persons  for
election  to the Board of  Directors  may be made at such a special  meeting  of
stockholders if the stockholder's notice as required by paragraph (A)(2) of this
By-Law shall be delivered to the Secretary at the principal executive offices of
the Corporation not earlier than the ninetieth day prior to such special meeting
and not later  than the close of  business  on the later of the  seventieth  day
prior to such special meeting or the tenth day following the day on which public
announcement  is  first  made of the  date  of the  special  meeting  and of the
nominees proposed by the Board of Directors to be elected at such meeting.

                  (C) General.

                  (1) Only  persons who are  nominated  in  accordance  with the
procedures  set the forth in this By-Law shall be eligible to serve as directors
and only such business shall be conducted at a meeting of  stockholders as shall
have been brought before the meeting in accordance with the procedures set forth
in this  By-Law.  Except  as  otherwise  provided  by law,  the  Certificate  of
Incorporation or these By-Laws, the chairman of the meeting shall have the power
and duty to  determine  whether a  nomination  or any  business  proposed  to be
brought before the meeting was made in accordance  with the procedures set forth
in this By-Law and, if any proposed  nomination or business is not in compliance
with this By-Law,  to declare that such defective  nomination shall be disregard
or that such proposed business shall not be transacted.

                  (2) For purposes of this By-Law,  "public  announcement" shall
mean  disclosure  in a press  release  reported  by the Dow Jones News  Service,
Associated Press or comparable  national news service or in a document  publicly
filed by the Corporation with the Securities and Exchange Commission pursuant to
Section 13, 14 or 15(d) of the Exchange Act.

                  (3) For purposes of this By-Law,  no adjournment nor notice of
adjournment  of any meeting  shall be deemed to  constitute a new notice of such
meeting  for  purposes  of this  Section  11, and in order for any  notification
required to be  delivered  by a  stockholder  pursuant to this  Section 11 to be
timely,  such  notification must be delivered within the periods set forth above
with respect to the originally scheduled meeting.

                  (4) Notwithstanding the foregoing provisions of this By-Law, a
stockholder  shall also comply with all applicable  requirements of the Exchange
Act and the rules and  regulations  thereunder  with  respect to the matters set
forth in this  By-Law.  Nothing  in this  By-Law  shall be deemed to affect  any
rights of  stockholders to request  inclusion of proposals in the  Corporation's
proxy statement pursuant to Rule 14a-8 under the Exchange Act.

                                   ARTICLE IV
                                    DIRECTORS

                  Section 1. The property and business of the Corporation  shall
be  managed  by its  Board  of  Directors,  the  members  of  which  need not be
stockholders.

                  Section 2. The Board of  Directors  of the  Corporation  shall
consist of such number of directors,  not less than three, as shall from time to
time be fixed exclusively by resolution of the Board of Directors. The directors
shall be divided into three  classes in the manner set forth in the  Certificate
of Incorporation  of the Corporation,  each class to be elected for the term set
forth therein.  Directors shall (except as hereinafter  provided for the filling
of vacancies  and newly  created  directorships)  be elected by the holders of a
plurality  of the voting  power  present in person or  represented  by proxy and
entitled to vote.

                  Section 3. Each  director  shall be elected to serve until his
successor  shall be elected and shall  qualify by evidence of acceptance of such
office and such acceptance shall be presumed in the absence of express rejection
thereof by the person elected within ten days after his knowledge of election. A
person who has passed his 64th birthday and who has not theretofore  served as a
director  of the  Corporation  shall not be  eligible  to be elected a director,
whether  pursuant to this Section 3 or to Section 6, of this  Article.  A person
who has passed his 70th birthday,  or who has retired as an employee,  shall not
in any  event be  eligible  for  reelection  to the  Board or be  qualified  for
continued  service  as a  director  of the  Corporation,  irrespective  of prior
service as a director of the  Corporation.  For  purposes of this  Section,  any
service as a director of {O Company} prior to the merger of {O Company} shall be
deemed to be prior service as a director of the Corporation.  Any failure of any
director to meet the qualifications for service as a director set forth in these
By-Laws,  or otherwise under law, shall result in the termination of the term of
such director.

                  Section 4. The directors may hold their meetings,  have one or
more offices and keep the books of the Corporation in the City of Oklahoma City,
Oklahoma,  or at such other places as they may from time to time  determine  and
designate.

                  Section 5. The   members  of  the  Board of  Directors  or any
committee  thereof may  participate in a meeting of such Board or committee,  as
the case may be, by means of  conference  telephone  or  similar  communications
equipment  by means of which all persons  participating  in the meeting can hear
each other,  and  participation  in a meeting  pursuant to this subsection shall
constitute presence in person at such a meeting.

                  Section 6. Vacancies  in  the  Board   of  Directors,  however
occasioned,  and newly created directorships  resulting from any increase in the
authorized  number  of  directors,  may be  filled  only  by a  majority  of the
remaining  directors  then in office though less than a quorum and the accepting
directors so chosen shall hold office for a term as set forth in the Certificate
of  Incorporation  of the  Corporation  and until a successor or successors have
been duly elected and qualified unless sooner displaced.

                  Section 7. Notwithstanding the foregoing, whenever the holders
of any one or more series of  Preferred  Stock issued by the  Corporation  shall
have the right,  voting separately by series, to elect directors at an annual or
special meeting of stockholders,  the election, term of office, removal, filling
of vacancies and other features of such  directorships  shall be governed by the
terms of the  Amended  and  Restated  Certificate  of  Incorporation  applicable
thereto,  and such  directors  so  elected  shall not be  divided  into  classes
pursuant  to  Article  SEVENTH  of  the  Amended  and  Restated  Certificate  of
Incorporation  unless expressly  provided by such terms. The number of directors
that may be elected by the holders of any such series of  Preferred  Stock shall
be in addition to the number  fixed by or  pursuant  to the  By-Laws.  Except as
otherwise  expressly  provided  in the  terms  of such  series,  the  number  of
directors  that may be so  elected by the  holders  of any such  series of stock
shall be elected for terms expiring at the next annual  meeting of  stockholders
and  without  regard  to the  classification  of the  members  of the  Board  of
Directors as set forth in Section 2 hereof,  and  vacancies  among  directors so
elected by the  separate  vote of the  holders of any such  series of  Preferred
Stock shall be filled by the  affirmative  vote of a majority  of the  remaining
directors elected by such series, or, if there are no such remaining  directors,
by the holders of such series in the same manner in which such series  initially
elected a director.

                  Section 8.  Subject to  provisions  of  pertinent  law and the
Certificate of Incorporation,  dividends,  if any, declared respecting any class
of shares of the  Corporation's  capital  stock may be  declared by the Board of
Directors  at any regular  meeting  thereof and  despite  any  provision  of the
By-Laws  to  the  contrary  at  any  special  meeting  thereof,  whether  or not
consideration  or action  respecting  dividends be stated in the notice thereof;
and dividends may be paid in cash or, if the declaration thereof so provides, in
property, including shares of the Corporation. There may be set aside out of any
funds of the  Corporation  available for dividends such sum or sums as the Board
of Directors  from time to time, in its absolute  discretion,  deems proper as a
reserve fund to meet contingencies,  or for equalizing dividends,  or for repair
or maintaining any property of the Corporation, or for such other purpose as the

change or  conversion  or exchange of capital  stock shall go into effect or for
any other purpose; provided, however, that in lieu of closing the stock transfer
books,  as  aforesaid,  the  Board of  Directors  may fix in  advance a date not
exceeding  sixty days preceding the date of any meeting of  stockholders  or the
date for the payment of any  dividend,  or the date for the allotment of rights,
or the date when any change or  conversion or exchange of capital stock shall go
into  effect,  or a date  for  such  other  purpose,  as a  record  date for the
determination  of the  stockholders  entitled  to notice of, and to vote at, any
such meeting or entitled to receive payment of any such dividend, or to any such
allotment  of rights,  or to exercise  the rights in respect of any such change,
conversion or exchange of capital stock, or for such other purpose,  and in such
case only such  stockholders  as shall be  stockholders of record on the date so
fixed shall be entitled to such notice of, and to vote at, such  meeting and any
adjournment,  thereof,  or to receive such  allotment of rights,  or to exercise
such rights or to be considered as stockholders  for such other purpose,  as the
case may be,  notwithstanding  any  transfer  of any  stock on the  books of the
Corporation after any such record date fixed as aforesaid.

                  Section 10. In addition to the powers and authorities by these
By-Laws  expressly  conferred  upon it, the Board of Directors  may exercise all
such powers of the Corporation and do all such lawful acts and things as are not

or required to be exercised or done by the stockholders.

                  Section 11. Any action  required or  permitted  to be taken at

such action a written  consent thereto is signed by all members of the Board and
such written consent is filed with the minutes of proceedings of the Board.

majority of members  thereof shall be necessary  and  sufficient to constitute a
quorum for the transaction of business, and the act of a majority of the members
present  at any  meeting  at which  there  is a  quorum  shall be the act of the
committee.

                  Section 5. Committees  of  the Board of  Directors  shall keep

shall be operative  during any emergency  resulting from an attack on the United
States, or during any nuclear or atomic disaster, or during the existence of any
catastrophe, or other similar emergency condition, as a result of which a quorum
of the Board of Directors  cannot readily be convened for action.  To the extent
not  inconsistent  with these emergency  bylaws,  the By-Laws of the Corporation
shall  remain in effect  during any  emergency  and upon its  termination  these
emergency bylaws shall cease to be operative.

                  Section 2. During any such emergency a meeting of the Board of
Directors  may be called by any officer or  director by giving two days'  notice
thereof to such of the  directors as it may be feasible to reach at the time and
by such means as may be feasible at the time.  The notice shall specify the time
and the place of the meeting,  which shall be the head office of the Corporation
or any other place specified in the notice. At any such meeting three members of
the then existing Board of Directors shall constitute a quorum, which may act by
majority vote.

                  Section 3. If the number of directors who are available to act

maximum  authority  possible under the Delaware  Corporation  Law, and all other
applicable  law,  to  conduct  the  interim  management  of the  affairs  of the
Corporation  in an emergency in what it considers to be in the best interests of
the Corporation  (including the right to amend this Article) irrespective of the
provisions of the Certificate of Incorporation or of the By-Laws.

acknowledge  or  verify  such  instrument  in more  than one  capacity  for such
purpose.

                  Section 2. Without  limiting   the  right  of   the  Board  of
Directors to choose officers of the Corporation at any time when vacancies occur
or when the number of officers is increased, the Board of Directors at the first
meeting after each annual meeting of stockholders shall choose a Chief Executive
Officer,  a President  and such other  officers as shall be  designated  at such
time,  including,  if so designated,  a Chairman of the Board,  one or more Vice

by the Board of Directors or  appointed by an officer in  accordance  with these
By-Laws shall have the powers and duties prescribed by law, by the By-Laws or by
the Board of Directors  and, in the case of appointed  officers,  the powers and
duties prescribed by the appointing officer, and, unless otherwise prescribed by
the By-Laws or by the Board of Directors or such appointing officer,  shall have
such further powers and duties as ordinarily pertain to that office.

                  Section 4. The salaries of all officers of the Corporation and
of its wholly owned subsidiaries, other than his own salary, shall be determined

Executive  Compensation Committee appointed by the Board of Directors from among
its members. The Executive  Compensation  Committee shall recommend to the Board
of  Directors  such  changes  in the  officers'  salaries  as fixed by the Chief
Executive  Officer as it may deem  appropriate  and the Board of Directors shall
instruct  the Chief  Executive  Officer to  implement  those of the  recommended
changes which it approves.  The salary of the Chief  Executive  Officer shall be
determined by the Board of Directors.

                  Section 5. The officers of the  Corporation  shall hold office
until  their  successors  are chosen and  qualify in their  stead.  Any  officer
elected or appointed  by the Board of Directors  may be removed at any time with

Directors.

be made on the records of the Corporation as may be provided by law.

                  Section 4. The  Corporation  shall  be  entitled  to treat the
holder of record of any share or shares of stock as the  holder in fact  thereof
and accordingly  shall not be bound to recognize any equitable or other claim to
or interest in such share or shares on the part of any other  person  whether or
not it shall have express or other notice thereof,  except as expressly provided
by the laws of Delaware.

                  Section 5. A new  certificate of stock of the  Corporation may
be issued in place of any certificate  theretofore issued by the Corporation and
alleged to have been lost, stolen or destroyed.

                  The Board of  Directors  may from time to time  prescribe  the
terms and  conditions  under which such new  certificates  may be issued.  Among
other things, the Board of Directors may require that the owner of the allegedly
lost,  stolen or destroyed  certificate,  or his legal  representatives,  submit
proper  evidence  in writing  and under oath that the alleged  loss,  theft,  or
destruction   actually   occurred,   and  may   require   that  such   owner  or
representatives give the Corporation a bond,  satisfactory to the Corporation as
to form and security,  sufficient to indemnify the Corporation against any claim
that may be made against it on account of the alleged loss, theft or destruction
of any such  certificate  or the  issuance  of any such new  certificate.  A new
certificate  may be issued  without  requiring any bond when, in the judgment of
the Board of Directors or of any officer of the Corporation to whom the Board of
Directors  may delegate  appropriate  authority,  it is proper to waive the bond
requirement.

                                   ARTICLE XIX
                   INSPECTION OF BOOKS, CHECKS AND FISCAL YEAR

                  Section 1. The Board of Directors shall determine from time to
time whether,  and, if allowed,  when and under what  conditions and regulations
the  accounts  and books of the  Corporation  (except  such as may by statute be
specifically  open  to  inspection),  or any  of  them,  shall  be  open  to the
inspection of the stockholders, and the stockholders' rights in this respect are
and shall be restricted and limited accordingly.

                  Section 2. Checks  or   demands  for   money  and notes of the
Corporation  may be signed by such officer or officers or such person or persons
other than those herein  authorized and in such manner as the Board of Directors
or the Chief Executive Officer may from time to time provide.

                  Section 3.   The  fiscal  year  shall begin  the  first day in
January of each year and end the  following  December 31.

                                   ARTICLE XX
                           DIRECTORS' ANNUAL STATEMENT

                  Section 1. The Board of Directors shall present at each annual
meeting  a full  and  clear  statement  of the  business  and  condition  of the
Corporation.

                                   ARTICLE XXI
                                     NOTICES

                  Section 1. Whenever under the provisions of the Certificate of
Incorporation  or of these  By-Laws  notice  (which as herein used shall include
also annual reports, proxy statements and solicitations and other communications
to holders of the Corporation's  securities) is required to be, or may be, given
to any director,  officer,  stockholder or other person,  it may, unless legally
controlling  provisions  prohibit  the same,  be given in writing,  by mail,  by
depositing the same in any U.S. post office or letter-box,  in a postpaid sealed
wrapper addressed to such person to whom the notice may be, or is required to be
given,  at such  address  as appears  on the books of the  Corporation,  and all
notices given in accordance  with the provisions of this Article shall be deemed
to be given at the time when the same shall be thus mailed.

                  Section 2. Should  a  person who is a  stockholder  own shares
evidenced by more than one stock certificate, nevertheless only one notice (when
any is  required  to be,  or may be,  given to  holders  of shares of any or all
classes)  shall be, in the sole  discretion of the  Corporation,  required to be
mailed  and if  different  addresses  as to  such  person  are  recorded  on the
Corporation's  stock ledger the notice may be mailed to the address that appears
to have been given latest in time unless the  stockholders  shall have expressly
directed  otherwise in writing to the  Secretary of the  Corporation,  nor shall
variations  in the  designation  of the name or identity of any one  stockholder
require the mailing of more than one notice to any one stockholder, which may be
mailed  to any one of the  names  or  designations  that  may so  appear  in the
Corporation's  stock ledger with respect to such  stockholder;  and, at the sole
discretion of the  Corporation,  the  distribution of dividend  payments may be,
unless a stockholder shall expressly request multiple  distributions strictly in
accordance with the stock ledger record of his multiple  ownerships,  handled in
accordance  with  or so as  not to be  repugnant  to the  purpose  of the  above
provisions, which is to avoid the expenditure by the Corporation of effort, time
and expense in such matters that might have been avoided had the  recording of a
stockholder's  name and/or address  incident to his multiple record ownership of
shares been effected accurately, uniformly and consistently.

                  Section 3. Any  stockholder,  director or officer may waive in
writing or otherwise  any notice  required to be given under the  provisions  of
pertinent statutes or of the Certificate of Incorporation or of these By-Laws. A
waiver of notice in  writing,  signed by the person or persons  entitled to said
notice,  whether  before  or after  the time  stated  therein,  shall be  deemed
equivalent to such notice.

                                  ARTICLE XXII
                                 INDEMNIFICATION

                  Section 1. The Corporation shall, to the full extent permitted
by the Laws of the State of Delaware as then in effect or, if less stringent, in
effect on  December  31,  1985  ("Delaware  Law"),  indemnify  any  person  (the
"Indemnitee")  made or threatened to be made a party to any threatened,  pending
or completed action, suit or proceeding, whether civil, criminal, administrative
or investigative  and whether or not by or in the right of the  Corporation,  by
reason of the fact that the Indemnitee is or was a director, officer or employee
of the  Corporation or is or was serving at the request of the  Corporation as a
director,  officer,  employee,  trustee,  partner,  or other  agent of any other
enterprise  or legal person (any such action,  suit or  proceeding  being herein
referred to as a "Legal  Action")  against all  expenses  (including  attorneys'
fees),  judgments,  fines and amounts paid in settlement actually and reasonably
incurred  by  the  Indemnitee  in  connection  with  such  Legal  Action  or its
investigation,  defense or appeal (herein called "Indemnified Expenses"), if the
Indemnitee  has met the  standard of conduct  necessary  under  Delaware  Law to
permit  such  indemnification.  Rights to  indemnification  shall  extend to the
heirs, beneficiaries, administrators and executors of any deceased Indemnitee.

                  For  purposes  of  this  Section,   reference  to  "any  other
enterprise or legal person" shall include employee benefit plans;  references to
"fines" shall  include any excise taxes  assessed on a person with respect to an
employee  benefit  plan;  and  references  to  "serving  at the  request  of the
Corporation" shall include any service as a director, officer, employee or agent
of the  Corporation  which  imposes  duties on, or  involves  services  by, such
director,  officer, employee, or agent with respect to an employee benefit plan,
its participants, or beneficiaries.

                  The  Indemnified  Expenses shall be paid by the Corporation in
advance as shall be  appropriate  to permit  Indemnitee  to defray such expenses
currently as incurred,  provided  the  Indemnitee  agrees in writing that in the
event it shall  ultimately be determined as provided  hereunder that  Indemnitee
was not entitled to be indemnified,  then Indemnitee shall promptly repay to the
Corporation  such amounts so paid. The prepayment of expenses as provided for in
this  Section 1 shall be  authorized  by the Board of  Directors in the specific
case  unless the Board of  Directors  receives  within  thirty  (30) days of the
Indemnitee's  request for  indemnification an opinion of counsel selected in the
manner  provided  for in  Section  2 of  this  Article  XXII  that  there  is no
reasonable  basis for a belief that the  Indemnitee's  conduct met the requisite
standard of conduct. The fees of such counsel and all related expenses shall, in
all cases, be paid by the Corporation.

                  Section 2. The determination of whether Indemnitee has met the
standard of conduct required to permit  indemnification  under this By-Law shall
in the first instance be submitted to the Board of Directors of the Corporation.
If the Board by a majority vote of a quorum consisting of directors who were not
parties to such Legal Action determines Indemnitee has met the required standard
of conduct  such  determination  shall be  conclusive;  but if such  affirmative
majority  vote is not given,  then the matter  shall be referred to  independent
legal  counsel for  determination.  Such  outside  counsel  shall be selected by
agreement of the Board of  Directors  and  Indemnitee  or, if they are unable to
agree,  then by lot from among those New York City law firms which (i) have more
than 100  attorneys,  (ii) have a  substantial  practice  in the  corporate  and
securities  areas  of  law,  (iii)  have  not  performed  any  services  for the
Corporation or any of its subsidiaries or affiliates for at least five (5) years
and  (iv)  have a  rating  of "av" in the then  current  Martindale-Hubbell  Law
Directory.  The fees and  expenses  of counsel in  connection  with  making this
determination shall be paid by the Corporation.

                  Notwithstanding  the  foregoing,   if  dissatisfied  with  the
determination  so  made  by  counsel,   Indemnitee  may  within  two  (2)  years
thereafter,  petition any court of competent  jurisdiction to determine  whether
Indemnitee is entitled to  indemnification  under the provisions hereof and such
court shall thereupon have the exclusive  authority to make such  determination.
The  Corporation  shall pay all expenses  (including  attorneys'  fees) actually
incurred by Indemnitee in connection with such judicial determination.

                  The  termination  of any  Legal  Action  by  judgment,  order,
settlement,  conviction,  or upon a plea of nolo  contendere or its  equivalent,
shall not, of itself,  create a presumption that the Indemnitee did not meet the
requisite  standard of conduct;  however, a successful defense of a Legal Action
by Indemnitee on the merits or otherwise shall conclusively establish Indemnitee
did meet such standard of conduct  notwithstanding any previous determination to
the contrary under thin Section 2.

                  Section 3. The indemnification and advance payment of expenses
as  provided in this  Article  XXII shall not be deemed  exclusive  of any other
rights to which  Indemnitee  may be entitled  under any  provision  of law,  the
Certificate of Incorporation, any By-Law or otherwise.

                  Section 4. If any provision of this Article XXII shall be held
to be invalid, illegal or unenforceable for any reason whatsoever, the validity,
legality and  enforceability  of the  remaining  provisions of this Article XXII
shall not in any way be affected or impaired thereby.

                  Section 5. Any  amendment,  repeal  or  modification  of these
By-Laws,  the  Corporation's  Certificate  of  Incorporation  or any  applicable
provision  of  Delaware  Law,  or any  other  instrument,  which  eliminates  or
diminishes the indemnification rights provided for in this Article XXII shall be
ineffective as against an Indemnitee with respect to any Legal Action based upon
actions  taken  or not  taken by the  Indemnitee  prior  to such  repeal  or the
adoption of such modification or amendment.  The provisions of this By-Law shall
be applicable to all Legal Actions made or commenced after the adoption  hereof,
whether  arising  from acts or omissions  to act  occurring  before or after its
adoption. The provisions of this By-Law shall be deemed to be a contract between
the  Corporation and each director or officer who serves in such capacity at any
time while this By-Law and the  relevant  provisions  of Delaware  Law and other
applicable law, if any, are in effect.  If any provision of this By-Law shall be
found  to be  invalid  or  limited  in  application  by  reason  of  any  law or
regulation, it shall not affect the validity of the remaining provisions hereof.
The rights of indemnification provided in this By-Law shall neither be exclusive
of, nor be deemed in  limitation  of, any rights to which an officer,  director,
employee or agent may  otherwise  be entitled or  permitted  by  contract,  this
By-Law,  vote of stockholders or directors or otherwise,  or as a matter of law,
both as to actions in such person's  official  capacity and actions in any other
capacity while holding such office,  it being the policy of the Corporation that
indemnification  of any person whom the  Corporation  is  obligated to indemnify
pursuant to this By-Law shall be made to the fullest extent permitted by law.

                                  ARTICLE XXIII
                                   AMENDMENTS

                  Section 1. These  By-Laws  may   be  altered   or  amended  or
repealed,  in whole or in part:  By the  affirmative  vote of the  holders  of a
majority of the stock issued and outstanding and entitled to a vote thereat,  at
any regular or special meeting of the  stockholders,  or by the affirmative vote
of a majority of the Board of Directors in  attendance at any regular or special
meeting of the Board of Directors;  provided, however, that, notwithstanding any
other  provisions of these By-Laws or any provision of law which might otherwise
permit a lesser vote of the stockholders, the affirmative vote of the holders of
at least 75 percent in voting power of all shares of the Corporation entitled to
vote generally in the election of directors,  voting together as a single class,
shall be  required  in order  for the  stockholders  to  alter,  amend or repeal
Section 8 and Section 11 of Article III,  Sections 2 and 6 of Article IV or this
proviso  to this  Article  XXIII of these  By-Laws  or to  adopt  any  provision
inconsistent with any of such Sections or with this proviso.

         THIS  REVOLVING  CREDIT  AGREEMENT is dated as of February 26, 1999, by
and among KERR-McGEE  CORPORATION,  a Delaware corporation (the "Company"),  the
Subsidiary  Borrowers  parties  hereto,  the  Lenders now or  hereafter  parties
hereto, and ROYAL BANK OF CANADA ("RBC"), as Administrative Agent.

         IT IS AGREED by the parties hereto as follows:


                                    ARTICLE I

                                   Definitions

         SECTION  1.01.  Defined   Terms.  As  used   in   this  Agreement,  the
following  terms  have  the  meanings specified below:

         "ABN Facility A" means  Facility A of and as defined in the Amended and
Restated Credit Agreement dated as of April 28, 1997 (as amended April 26, 1998)
with the Company and Kerr-McGee Oil (U.K.) PLC as Borrowers,  the banks, and ABN
AMRO Bank N.V. as Agent.

         "ABR",  when  used in  reference  to any Loan or  Borrowing,  refers to
whether such Loan, or the Loans comprising such Borrowing,  are bearing interest
at a rate determined by reference to the Alternate Base Rate.

be  followed  by the  phrase  "without  limitation".  The word  "will"  shall be
construed  to have the same meaning and effect as the word  "shall".  Unless the
context  requires  otherwise,  any  definition of or reference to any agreement,
instrument  or other  document  herein  shall be  construed as referring to such
agreement,   instrument  or  other  document  as  from  time  to  time  amended,
supplemented  or  otherwise  modified  (subject  to  any  restrictions  on  such
amendments, supplements or modifications set forth herein), any reference herein
to any  Person  shall be  construed  to include  such  Person's  successors  and
assigns,  and the words  "asset" and  "property"  shall be construed to have the
same  meaning  and effect and to refer to any and all  tangible  and  intangible
assets and properties, including cash, securities, accounts and contract rights.

         SECTION  1.04.  Accounting  Terms;  GAAP.  Unless  otherwise  specified
herein,  all accounting  terms used herein shall be interpreted,  all accounting
determinations hereunder shall be made, and all financial statements required to
be delivered  hereunder  shall be prepared in accordance with GAAP, as in effect
from time to time,  applied on a basis consistent  (except for changes concurred
in by  the  Company's  independent  public  accountants  and  disclosed  in  the
financial  statements)  with  the most  recent  audited  consolidated  financial
statements  of the Company and its  Consolidated  Subsidiaries  delivered to the
Lenders.

         SECTION 1.05. Euros as Payment for National Currencies.  Subject to any
applicable  EMU  Legislation,  with  respect  to each  Loan made  hereunder  and
denominated in a National  Currency,  it is agreed that the applicable  Borrower
may make any payment with respect thereto,  whether of principal or interest, in
either such National Currency or in Euros, and if in Euros, then in an amount in
Euros equal to the applicable  National Currency calculated pursuant to the then
applicable  conversion rate between the Euro and such National  Currency.  As of
December 31, 1998,  the European  Council  caused the  conversion  rates for the
National Currencies and the Euro to be irrevocably fixed.

         SECTION  1.06.  Calculation  of  Dollar  Equivalent  Amounts.  For  all
purposes of this  Agreement  where it is or becomes  necessary to calculate  the
amount of availability of the Commitments,  the Domestic Available Amount or the
Foreign Available Amount or, in connection therewith,  the outstanding amount of
the Loans,  the  Revolving  Credit  Exposure or the Credit  Exposure,  each such
calculation shall be made in accordance with the context of how any such term is
used, by determining the Dollar amount,  the Dollar Equivalent of the applicable
Alternative  Currencies  or  the  sum of  the  Dollar  amount  plus  the  Dollar
Equivalent of the applicable Alternate Currencies, as applicable.


                                   ARTICLE II

                                   The Credits

         SECTION  2.01.  Commitments.  Subject to the terms and  conditions  set
forth herein,  each Lender  severally  agrees to (i) make Revolving Loans (a) to
the Company and the Domestic Subsidiary Borrowers or any one or more of them, up
to the Domestic Available Amount, and (b) to the Foreign Subsidiary Borrowers or
any one or more of them, up to the Foreign Available  Amount,  from time to time
during the  Availability  Period in an aggregate  principal amount that will not
result in such  Lender's  Revolving  Credit  Exposure  exceeding  such  Lender's
Commitment;  and (ii) at the election of the Company,  to convert the  principal
amount of any  Revolving  Loans  remaining  outstanding  on the  Revolving  Loan
Maturity  Date to Term  Loans.  Within the  foregoing  limits and subject to the
terms and  conditions  set forth  herein,  any  Borrower  may make more than one
Borrowing  on any Business  Day and may borrow,  prepay and  reborrow  Revolving
Loans.

         SECTION 2.02. Loans and Borrowings. (a) Each Loan shall be made as part
of a Borrowing  consisting  of Loans made by the Lenders  ratably in  accordance
with their  respective  Commitments.  The failure of any Lender to make any Loan
required to be made by it shall not relieve any other Lender of its  obligations
hereunder;  provided  that the  Commitments  of the  Lenders  are several and no
Lender  shall be  responsible  for any other  Lender's  failure to make Loans as
required.

                  (b) Subject to Section 2.11, each Revolving Borrowing shall be
made  entirely in LIBOR  Loans,  EURIBOR  Loans,  CD Loans or ABR Loans,  as the
Company may request in accordance herewith. Each Lender, at its option, may make
any LIBOR Loan or EURIBOR  Loan by causing  any  domestic  or foreign  branch or
Affiliate of such Lender to make such Loan;  provided  that any exercise of such
option shall not affect the obligation of a Borrower to repay such Loans made to
it in accordance  with the terms of this  Agreement;  and provided  further that
each Lender shall have an office, or a branch,  or an Affiliate  available to it
and located in the appropriate  jurisdiction  through which such Lender can make
any Eurodollar Loan or any Loan denominated in an Alternate Currency as required
under this Agreement.

                  (c) At the  commencement  of each initial  Interest Period for
(i) any  Borrowing  comprised of LIBOR Loans,  EURIBOR  Loans or CD Loans,  such
Borrowing  shall be in an  aggregate  amount  that is an  integral  multiple  of
1,000,000 units of the applicable  currency thereof and not less than 10,000,000
units of such currency.  At the time that each Borrowing  comprised of ABR Loans
is made,  such  Borrowing  shall be in an  aggregate  amount that is an integral
multiple of  $1,000,000  and not less than  $10,000,000;  provided that such ABR
Borrowing  may be in an  aggregate  amount  that is equal to the  entire  unused
balance of the Domestic  Available Amount or the Foreign  Available  Amount,  as
applicable. Borrowings of more than one Type and Class may be outstanding at the
same time; provided that there shall not at any time be more than a total of ten
CD, EURIBOR and LIBOR Borrowings outstanding.

                  (d) Notwithstanding any other provision of this Agreement, (i)
the  Company,  on behalf of itself or any  Borrower,  shall not be  entitled  to
request, or to elect to convert (except for a conversion to a Term Loan pursuant
to Section  2.21) or  continue,  any  Revolving  Loan  Borrowing if the Interest
Period  requested  with  respect  thereto  would end after  the  Revolving  Loan
Maturity Date and (ii) the Company,  on behalf of itself or any Borrower,  shall
not be entitled to request, or elect to convert or continue,  any Term Borrowing
if the Interest Period  requested with respect thereto would end after the Final
Maturity Date.

         SECTION 2.03. Requests for Revolving Borrowings. To request a Revolving
Borrowing,  the Company shall notify the Administrative Agent of such request by
hand delivery or telecopy of a Borrowing Request or by telephone (a) in the case
of a Eurodollar LIBOR Borrowing,  not later than 11:00 a.m., New York City time,
three Business Days before the date of the proposed  Borrowing,  (b) in the case
of a Sterling LIBOR Borrowing or a EURIBOR Borrowing, not later than 11:00 a.m.,
New  York  City  time,  four  Business  Days  before  the  date of the  proposed
Borrowing,  (c) in the case of a CD  Borrowing,  not later than 11:00 a.m.,  New
York City time, two Business Days before the date of the proposed Borrowing, and
(d) in the case of an ABR  Borrowing,  not later than 11:00 a.m.,  New York City
time,  one  Business Day before the date of the  proposed  Borrowing.  Each such
telephonic  Borrowing  Request  shall be  irrevocable  and  shall  be  confirmed
promptly by hand delivery or telecopy to the  Administrative  Agent of a written
Borrowing Request in a form approved by the  Administrative  Agent and signed by
the Company.  Each such telephonic and written  Borrowing  Request shall specify
the following information in compliance with Section 2.02:

                  (i)  the applicable Borrower;

                  (ii)  the aggregate amount of the requested Borrowing;

                  (iii) the date of such  Borrowing,  which  shall be a Business
         Day;

                  (iv)  whether  such  Borrowing  is to be made in Dollars or an
         Alternate Currency, and if such Borrowing is to be made in an Alternate
         Currency, which Alternate Currency;

                  (v) whether  such  Borrowing is to be a CD  Borrowing,  an ABR
         Borrowing, a EURIBOR Borrowing or a LIBOR Borrowing;

                  (vi) in the case of a CD  Borrowing,  a EURIBOR  Borrowing  or
         LIBOR Borrowing,  the initial Interest Period to be applicable thereto,
         which  shall be a period  contemplated  by the  definition  of the term
         "Interest Period"; and

                  (vii) the  location  and number of the  applicable  Borrower's
         account to which funds are to be disbursed, which shall comply with the
         requirements of Section 2.04.

If no election as to the Type of any Revolving Borrowing  denominated in Dollars
is specified,  then the requested Revolving Borrowing shall be an ABR Borrowing.
If no Interest  Period is specified with respect to any requested CD, EURIBOR or
LIBOR Revolving Borrowing,  then the Company shall be deemed to have selected an
Interest  Period of 30 days'  duration,  in the case of a CD  Borrowing,  or one
month's duration, in the case of a EURIBOR Borrowing or a LIBOR Borrowing. If no
election as to the  currency of the  Borrowing  is  specified,  then the Company
shall be deemed to have  selected  Dollars;  provided  that in no event  shall a
Borrowing deemed to be denominated in Dollars bear interest at a rate other than
the Adjusted  Eurodollar  LIBO Rate,  the Adjusted CD Rate or the Alternate Base
Rate.  Promptly following receipt of a Borrowing Request in accordance with this
Section,  the  Administrative  Agent  shall  advise  each  Lender of the details
thereof  and of the  amount  of  such  Lender's  Loan  to be made as part of the
requested Borrowing.

         SECTION 2.04.  Funding of  Borrowings.  (a) Each Lender shall make each
Loan to be made by it hereunder on the proposed date thereof by wire transfer of
immediately  available  funds by 12:00 noon,  New York City time, in the case of
Dollar  Borrowings,  and by 12:00 noon,  London time,  in the case of Borrowings
denominated in an Alternate  Currency,  to the applicable Agency Account for the
account of the  applicable  Borrower.  The  Administrative  Agent will make such
Loans available to the applicable  Borrower by promptly crediting the amounts so
received,  in like  funds,  to an account  of such  Borrower  designated  by the
Company in the applicable Borrowing Request.

                  (b) Unless the Administrative Agent shall have received notice
from a Lender prior to the proposed date of any Borrowing  that such Lender will
not make  available  to the  Administrative  Agent such  Lender's  share of such
Borrowing,  the  Administrative  Agent may assume that such Lender has made such
share  available on such date in accordance  with  paragraph (a) of this Section
and may, in reliance  upon such  assumption,  make  available to the  applicable
Borrower a corresponding amount. In such event, if a Lender has not in fact made
its share of the applicable  Borrowing  available to the  Administrative  Agent,
then the applicable Lender and the applicable Borrower severally agree to pay to
the  Administrative  Agent  forthwith on demand such  corresponding  amount with
interest  thereon,  for each day from and including the date such amount is made
available to the applicable Borrower to but excluding the date of payment to the
Administrative  Agent,  at (i) in the case of such  Lender,  the  greater of the
Federal Funds Effective Rate and a rate determined by the  Administrative  Agent
in accordance with banking  industry rules on interbank  compensation or (ii) in
the case of the applicable Borrower,  the interest rate applicable to ABR Loans.
If such Lender pays such amount to the  Administrative  Agent,  then such amount
shall constitute such Lender's Loan included in such Borrowing.

         SECTION  2.05.  Interest   Elections.   (a)  Each  Revolving  Borrowing
initially  shall be of the Type  specified in the applicable  Borrowing  Request
and, in the case of a CD, EURIBOR or LIBOR  Revolving  Borrowing,  shall have an
initial Interest Period as specified in such Borrowing Request.  Thereafter, the
Company may elect to convert such  Borrowing to a different  Type or to continue
such Borrowing and, in the case of a CD, EURIBOR or LIBOR  Borrowing,  may elect
Interest  Periods  therefor,  all as provided in this  Section.  The Company may
elect  different  options  with  respect to  different  portions of the affected
Borrowing,  in which case each such portion shall be allocated ratably among the
Lenders holding the Loans  comprising such Borrowing,  and the Loans  comprising
each such portion shall be considered a separate Borrowing.

                  (b) To make an election pursuant to this Section,  the Company
shall  notify the  Administrative  Agent of such  election  by hand  delivery or
telecopy  of an Interest  Election  Request or by  telephone  by the time that a
Borrowing  Request  would be required  under  Section  2.03 if the Company  were
requesting a Revolving  Borrowing of the Type resulting from such election to be
made on the  effective  date of such  election.  Each such  telephonic  Interest
Election  Request shall be irrevocable  and shall be confirmed  promptly by hand
delivery or telecopy to the Administrative  Agent of a written Interest Election
Request  in a form  approved  by the  Administrative  Agent  and  signed  by the
Company.

                  (c) Each  telephonic  and written  Interest  Election  Request
shall specify the following information in compliance with Section 2.02:

                  (i) the  Borrowing  to which such  Interest  Election  Request
         applies  and, if  different  options are being  elected with respect to
         different  portions  thereof,  the portions  thereof to be allocated to
         each resulting Borrowing (in which case the information to be specified
         pursuant to clauses  (iii) and (iv) below shall be  specified  for each
         resulting Borrowing);

                  (ii) the effective  date of the election made pursuant to such
         Interest Election Request, which shall be a Business Day;

                  (iii)  whether  the  resulting  Borrowing  is  to  be  an  ABR
         Borrowing, a CD Borrowing, a EURIBOR Borrowing or a LIBOR Borrowing;

                  (iv) if the resulting  Borrowing is a CD Borrowing,  a EURIBOR
         Borrowing or a LIBOR  Borrowing,  the Interest  Period to be applicable
         thereto after giving effect to such  election,  which shall be a period
         contemplated by the definition of the term "Interest Period".

If any such  Interest  Election  Request  requests  a CD  Borrowing,  a  EURIBOR
Borrowing or a LIBOR Borrowing,  but does not specify an Interest  Period,  then
the Company  shall be deemed to have  selected  an  Interest  Period of 30 days'
duration, in the case of a CD Borrowing, or one month's duration, in the case of
a EURIBOR Borrowing or a LIBOR Borrowing.

                  (d)  Promptly   following  receipt  of  an  Interest  Election
Request,  the  Administrative  Agent  shall  advise  each  Lender of the details
thereof and of such Lender's portion of each resulting Borrowing.

                  (e) If the Company fails to deliver a timely Interest Election
Request with respect to a CD Borrowing, a EURIBOR Borrowing or a LIBOR Borrowing
prior to the end of the Interest Period  applicable  thereto,  then, unless such
Borrowing is repaid as provided herein, at the end of such Interest Period,  (i)
if such  Borrowing is  denominated  in Dollars,  it shall be converted to an ABR
Borrowing and (ii) if such Borrowing is  denominated  in an Alternate  Currency,
the Company shall be deemed to have  selected an Interest  Period of one month's
duration.  Notwithstanding any contrary provision hereof, if an Event of Default
has occurred and is continuing and the  Administrative  Agent, at the request of
the Required  Lenders,  so notifies the  Company,  then,  so long as an Event of
Default is continuing (i) no outstanding Borrowing denominated in Dollars may be
converted to or continued as a CD Borrowing or a LIBOR Borrowing and (ii) unless
repaid, (A) in the case of Borrowings  denominated in Dollars, each CD Borrowing
and each LIBOR  Borrowing  shall be converted to an ABR  Borrowing at the end of
the  Interest  Period  applicable  thereto,  and (B) in the  case of  Borrowings
denominated  in an  Alternate  Currency,  the  Company  shall be  deemed to have
selected an Interest Period of one month's duration.

         SECTION 2.06.  Termination or Reduction of Commitments.

                  (a)  Unless   previously   terminated  the  Commitments  shall
terminate on the Revolving Loan Maturity Date as provided in Section 2.21.

                  (b) The  Company  may at any time  terminate,  or from time to
time reduce, the Commitments with such reductions applicable in whole or in part
to the Domestic  Available Amount or the Foreign Available Amount, at the option
of the Company;  provided that (i) each reduction of the Commitments shall be in
an  amount  that  is an  integral  multiple  of  $5,000,000  and not  less  than
$20,000,000  and (ii) the Company shall not terminate or reduce the  Commitments
if, after giving effect to any concurrent  prepayment of the Loans in accordance
with Section 2.08, (A) the sum of the Revolving  Credit  Exposures  would exceed
the  total  Commitments,  (B)  with  respect  to the  Company  and the  Domestic
Subsidiary Borrowers,  the sum of the Revolving Credit Exposures attributable to
such Borrowers would exceed the Domestic  Available Amount, and (C) with respect
to the Foreign Subsidiary  Borrowers,  the sum of the Revolving Credit Exposures
attributable to such Borrowers would exceed the Foreign Available Amount.

                  (c) The Company shall notify the  Administrative  Agent of any
election to  terminate or reduce the  Commitments  under  paragraph  (b) of this
Section  at  least  five  Business  Days  prior  to the  effective  date of such
termination  or  reduction,  specifying  such  election and the  effective  date
thereof.  Promptly  following receipt of any notice,  the  Administrative  Agent
shall advise the Lenders of the contents  thereof.  Each notice delivered by the
Company pursuant to this Section shall be irrevocable; provided that a notice of
termination  of the  Commitments  delivered  by the  Company may state that such
notice is conditioned  upon the  effectiveness  of other credit  facilities,  in
which  case  such  notice  may be  revoked  by the  Company  (by  notice  to the
Administrative  Agent  on or  prior  to the  specified  effective  date) if such
condition is not  satisfied.  Any  termination  or reduction of the  Commitments
shall be  permanent.  Each  reduction of the  Commitments  shall be made ratably
among the Lenders in accordance with their respective Commitments.

         SECTION 2.07.  Repayment of Loans;  Evidence of Debt. (a) Each Borrower
hereby  unconditionally  promises to pay (i) to the Administrative Agent for the
account of each Lender the then unpaid principal amount of each of its Revolving
Loans on the  Revolving  Loan  Maturity  Date  (unless  converted  to Term Loans
pursuant to Section 2.21) and (ii) to the  Administrative  Agent for the account
of each Lender the then unpaid  principal  amount of each Term Loan on the Final
Maturity Date; provided, that the Revolving Loans made by a Non-Extending Lender
shall be repaid as provided in Section 2.18.

                  (b) Each Lender shall  maintain in  accordance  with its usual
practice an account or accounts  evidencing the indebtedness of each Borrower to
such  Lender  resulting  from each Loan  made by such  Lender to such  Borrower,
including the amounts of principal and interest  payable and paid to such Lender
from time to time hereunder.

                  (c) The Administrative  Agent shall maintain accounts in which
it shall record (i) the amount of each Loan made  hereunder,  the Class and Type
thereof  and the  Interest  Period  applicable  thereto,  (ii) the amount of any
principal  or interest  due and  payable or to become due and payable  from each
Borrower to each Lender  hereunder  and (iii) the amount of any sum  received by
the  Administrative  Agent  hereunder  from a  Borrower  for the  account of the
Lenders and each Lender's share thereof.

                  (d) The entries  made in the accounts  maintained  pursuant to
paragraph  (b) or (c) of this  Section  shall be  prima  facie  evidence  of the
existence and amounts of the  obligations  recorded  therein;  provided that the
failure of any Lender or the  Administrative  Agent to maintain such accounts or
any error therein shall not in any manner affect the obligation of each Borrower
to repay the Loans in accordance with the terms of this Agreement.

                  (e) Any Lender may request  that Loans made by it be evidenced
by a promissory  note. In such event,  the  applicable  Borrower  shall prepare,
execute  and deliver to such Lender a  promissory  note  payable to the order of
such Lender (or, if requested by such Lender,  to such Lender and its registered
assigns) and in a form approved by the  Administrative  Agent.  Thereafter,  the
Loans evidenced by such promissory note and interest  thereon shall at all times
(including after assignment  pursuant to Section 10.04) be represented by one or
more  promissory  notes in such form  payable  to the  order of the payee  named
therein (or, if such promissory note is a registered note, to such payee and its
registered assigns).

                  (f) Any Loan made hereunder  shall be repaid by the applicable
Borrower or Borrowers in the currency that such Loan was originally  denominated
or deemed to be denominated;  provided,  however, that any Loan denominated in a
National Currency may be repaid in Euros in accordance with Section 1.05.

         SECTION  2.08.  Prepayment  of Loans.  (a) Any Borrower  shall have the
right at any time and from time to time to prepay any  Borrowing  in whole or in
part,  subject to prior notice in accordance with paragraph (b) of this Section;
provided that each  prepayment  of a Borrowing  shall be in an amount that is an
integral multiple of $1,000,000 and not less than $10,000,000.

                  (b) The applicable  Borrower  shall notify the  Administrative
Agent  by  telephone  (confirmed  immediately  by  telecopy)  of any  prepayment
hereunder  (i) in the case of prepayment  of a Eurodollar  Borrowing,  not later
than 11:00  a.m.,  New York City time,  three  Business  Days before the date of
prepayment,  (ii) in the case of prepayment of a Sterling  LIBOR  Borrowing or a
EURIBOR Borrowing,  not later than 11:00 a.m., New York City time, four Business
Days  before the date of  prepayment,  (iii) in the case of  prepayment  of a CD
Borrowing,  not later than 11:00 a.m.,  New York City time,  two  Business  Days
before  the  date of  prepayment,  or (iv) in the case of  prepayment  of an ABR
Borrowing,  not later than 11:00  a.m.,  New York City time,  one  Business  Day
before the date of prepayment.  Each such notice shall be irrevocable  and shall
specify  the  prepayment  date and the  principal  amount of each  Borrowing  or
portion thereof to be prepaid; provided that, if a notice of prepayment is given
in connection  with a conditional  notice of termination  of the  Commitments as
contemplated  by Section 2.06,  then such notice of prepayment may be revoked if
such notice of termination is revoked in accordance with Section 2.06.  Promptly
following receipt of any such notice relating to a Borrowing, the Administrative
Agent shall advise the Lenders of the contents thereof.  Each partial prepayment
of any Borrowing shall be in an amount that would be permitted in the case of an
advance  of a  Borrowing  of the same Type as  provided  in Section  2.02.  Each
prepayment of a Borrowing  shall be applied ratably to the Loans included in the
prepaid  Borrowing.  Prepayments shall be accompanied by accrued interest to the
extent  required by Section 2.10.  Each  prepayment  shall include break funding
payments to the extent required by Section 2.13.

                  (c) In the event that (i) the  aggregate  principal  amount of
all Loans under this Agreement exceeds the total aggregate Lenders' Commitments;
(ii) the  aggregate  principal  amount of all Loans made to the  Company and the
Domestic  Subsidiary  Borrowers exceeds the Domestic  Available Amount; or (iii)
the  aggregate  principal  amount of all Loans  made to the  Foreign  Subsidiary
Borrowers  exceeds the Foreign  Available  Amount; in each case as determined by
the aggregate of all applicable  Dollar  Borrowings and the Dollar Equivalent of
all applicable  Alternate Currency  Borrowings on the first Business Day of each
month then, at the request of the  Administrative  Agent, the Company shall, and
shall cause each  Subsidiary  Borrower to,  prepay (A) in the case of clause (i)
above,  immediately,  and (B) in the case of clauses (ii) or (iii) above, within
three Business Days of such request,  an amount equal to the excess described in
clauses (i),  (ii), and (iii) above,  as  applicable,  or in the case of clauses
(ii) and (iii) above,  provide cash collateral by making a deposit in an account
with the Administrative  Agent, in the name of the Administrative  Agent and for
the benefit of the Lenders,  of an amount in cash and in the same currency so as
to equal  such  excess as of such  date plus any  accrued  and  unpaid  interest
thereon,  which cash  collateral  shall be  collaterally  assigned  as  security
pursuant to the Cash  Collateral  Account  Agreement,  which  agreement shall be
executed  and   delivered  by  the   Borrowers  to  the   Administrative   Agent
contemporaneously  with the payment of such cash  collateral;  provided that the
obligation to deposit such cash collateral shall become  effective  immediately,
and such deposit shall become  immediately  due and payable,  without  demand or
other  notice of any kind,  upon the  occurrence  of any Event of  Default  with
respect to any  Borrower  described in clause (h) or (i) of Article  VIII.  Such
deposit shall be held by the Administrative  Agent as collateral for the payment
and performance of the  obligations of the Borrowers  under this Agreement.  The
Administrative  Agent shall have exclusive  dominion and control,  including the
exclusive right of withdrawal, over such account. Other than any interest earned
on the  investment  of such  deposits,  which  investments  shall be made at the
option and sole  discretion of the  Administrative  Agent and at the  Borrowers'
risk and expense, such deposits shall not bear interest. Interest or profits, if
any,  on such  investments  shall  accumulate  in such  account.  Moneys in such
account shall be applied by the Administrative  Agent to satisfy  obligations of
the Borrowers  under this  Agreement.  If any Borrower is required to provide an
amount  of  cash  collateral  hereunder  as a  result  of  a  request  from  the
Administrative  Agent for a prepayment  under this Section,  such amount (to the
extent not applied as aforesaid) shall be returned to such Borrower within three
Business  Days after the earlier of (x) the first  Business  Day of a month that
the  Administrative  Agent  determines  that such cash  collateral  is no longer
required  pursuant to the terms of the first  sentence of this Section and (y) a
prepayment of the Loans in an amount equal to such cash collateral.

         (d) If the Borrowers' fail to satisfy any one or more of the conditions
precedent set forth in Section 4.02 for any Refunding Borrowing, the Company and
each  Subsidiary  Borrower shall repay its Loans (i) in the case of LIBOR Loans,
EURIBOR  Loans or CD Loans,  on the last day of the Interest  Period  applicable
thereto, and (ii) in the case of Base Rate Loans, on or before the fifteenth day
following the day on which notice is given by the Company or the  Administrative
Agent of the failure to satisfy any such condition precedent.

                  SECTION  2.09.  Fees.  (a) The  Company  agrees  to pay to the
Administrative  Agent for the account of each Lender a facility fee, which shall
accrue at the  Applicable  Rate for  facility  fees on the  daily  amount of the
Commitment of such Lender  (whether  used or unused)  during the period from and
including the Closing Date to but  excluding  the date on which such  Commitment
terminates;  provided that, if such Lender continues to have any Credit Exposure
after its Commitment terminates, then such facility fee shall continue to accrue
on the daily amount of such Lender's Credit Exposure from and including the date
on which its  Commitment  terminates  to but  excluding  the date on which  such
Lender  ceases to have any  Credit  Exposure.  Accrued  facility  fees  shall be
payable in arrears on the last day of March,  June,  September  and  December of
each year and on the date on which the Commitments terminate,  commencing on the
first such date to occur after the date hereof;  provided that any facility fees
accruing after the date on which the  Commitments  terminate shall be payable on
demand.  All facility  fees shall be computed on the basis of a year of 360 days
and shall be payable for the actual number of days elapsed  (including the first
day but excluding the last day).

                  (b) The Borrowers agree to pay to the Administrative Agent for
the  account  of each  Lender  a  utilization  fee  which  shall  accrue  at the
Applicable Rate for utilization fees on the daily amount of such Lender's Credit
Exposure during the time the sum of the total Credit Exposures equals or exceeds
33% of the total Commitments. Utilization fees shall be computed on the basis of
a year of 360 days and shall be  payable  in  arrears  on the last day of March,
June,  September and December of each year.  Each  Subsidiary  Borrower shall be
severally  obligated  to pay  its  portion  of  such  fees  with  regard  to its
Borrowings hereunder.  Notwithstanding the foregoing, the Company agrees that it
will remain obligated for all such fees.

                  (c) The Company agrees to pay to the Administrative Agent, for
its own account,  such fees as are set forth in the Fee Letter, on the dates and
in the manner specified therein.

                  (d) All fees payable hereunder shall be paid on the dates due,
in immediately available funds, to the Administrative Agent, for its own account
or for  distribution,  in the case of facility fees and utilization fees, to the
Lenders. Fees paid shall not be refundable under any circumstances.

         SECTION 2.10.  Interest.  (a) The Loans  comprising  each ABR Borrowing
shall bear  interest for each day such Loans are  outstanding  at the  Alternate
Base Rate for such day. Any change in the Alternate Base Rate due to a change in
the Royal Bank Prime Rate or the Federal Funds Effective Rate shall be effective
from and  including  the  effective  date of such change in the Royal Bank Prime
Rate or the Federal Funds Effective Rate, as applicable.

                  (b) The Loans comprising each CD Borrowing shall bear interest
at the  Adjusted CD Rate for the  Interest  Period in effect for such  Borrowing
plus the Applicable Rate for LIBOR Borrowings plus 0.125% per annum.

                  (c) The Loans  comprising  each  LIBOR  Borrowing  shall  bear
interest at the  Adjusted  Eurodollar  LIBO Rate or the Adjusted  Sterling  LIBO
Rate, as applicable,  for the Interest  Period in effect for such Borrowing plus
the Applicable Rate.

                  (d) The Loans  comprising  each EURIBOR  Borrowing  shall bear
interest  at  Adjusted  EURIBOR  for the  Interest  Period  in  effect  for such
Borrowing plus the Applicable Rate.

                  (e)  Notwithstanding  the  foregoing,  if any  principal of or
interest  on any  Loan or any fee or  other  amount  payable  by the  applicable
Borrower  hereunder  is not paid when due,  whether  at  stated  maturity,  upon
acceleration  or otherwise,  such overdue amount shall bear  interest,  after as
well as before judgment, at a rate per annum equal to 2% plus the rate otherwise
applicable to such Loan as provided in the preceding paragraphs of this Section.

                  (f) Accrued  interest on each Loan shall be payable in arrears
on each Interest Payment Date for such Loan and, in the case of Revolving Loans,
upon termination of the Commitments; provided that (i) interest accrued pursuant
to paragraph (e) of this Section  shall be payable on demand,  (ii) in the event
of any  repayment or  prepayment  of any Loan (other than a prepayment of an ABR
Loan  prior to the end of the  Availability  Period),  accrued  interest  on the
principal  amount  repaid  or  prepaid  shall  be  payable  on the  date of such
repayment or prepayment and (iii) in the event of any conversion of any EURIBOR,
CD or LIBOR  Loan  prior to the end of the  current  Interest  Period  therefor,
accrued  interest  on such Loan shall be payable on the  effective  date of such
conversion.

                  (g) All interest hereunder shall be computed on the basis of a
year of 360 days,  except that interest on ABR Loans  calculated by reference to
the Royal Bank Prime Rate shall be  computed  on the basis of a year of 365 days
(or 366 days in a leap  year),  and in each case shall be payable for the actual
number of days elapsed (including the first day but excluding the last day). The
applicable  interest  rates shall be determined by the  Administrative  Agent in
accordance with the terms of this  Agreement,  and such  determination  shall be
conclusive absent manifest error.

                  (h) All interest  accruing on any Loan hereunder shall be paid
in the currency in which such Loan is denominated  or deemed to be  denominated;
provided,  however,  that the  interest  accruing on any Loan  denominated  in a
National Currency may be paid in Euros in accordance with Section 1.05.

         SECTION 2.11.  Alternate Rate of Interest. If prior to the commencement
of  any  Interest  Period  for a CD  Borrowing,  a  EURIBOR Borrowing or a LIBOR
Borrowing:

                  (a) the Administrative Agent:

                  (i) determines (which determination shall be conclusive absent
         manifest  error) that  adequate and  reasonable  means do not exist for
         ascertaining  the Adjusted CD Rate, the Adjusted  Eurodollar LIBO Rate,
         the Adjusted Sterling LIBO Rate or Adjusted EURIBOR, as applicable, for
         such Interest Period; or

                  (ii) is advised by the  Required  Lenders that the Adjusted CD
         Rate, the Adjusted  Eurodollar  LIBO Rate,  the Adjusted  Sterling LIBO
         Rate, or Adjusted EURIBOR, as applicable, for such Interest Period will
         not  adequately and fairly reflect the cost to such Lenders (or Lender)
         of making or  maintaining  their  Loans (or its Loan)  included in such
         Borrowing for such Interest Period;

then the  Administrative  Agent shall give notice  thereof to the  Company,  the
applicable  Borrower  and the  Lenders by  telephone  or telecopy as promptly as
practicable thereafter and, until the Administrative Agent notifies the Company,
the applicable  Borrower and the Lenders that the  circumstances  giving rise to
such notice no longer exist, (A) any Interest Election Request that requests the
conversion  of any  Borrowing  to, or  continuation  of any  Borrowing  as, a CD
Borrowing, a EURIBOR Borrowing,  or a LIBOR Borrowing,  as applicable,  shall be
ineffective,  (B) if any  Borrowing  Request  requests a CD Borrowing or a LIBOR
Borrowing, as applicable,  if such Borrowing is to be denominated in Dollars, it
shall be made as an ABR  Borrowing  and (C) any  request  for a EURIBOR or LIBOR
Borrowing  denominated in an Alternate  Currency shall be ineffective;  provided
that if the  circumstances  giving  rise to such  notice do not  affect all such
Types of  Borrowings,  then the other  unaffected  Types of Borrowings  shall be
permitted.

                  (b) If, in relation to any Borrowing or proposed  Borrowing to
be denominated in an Alternate Currency, and with respect to any Interest Period
relative thereto:

                  (i) the Administrative Agent shall have received  notification
         from a  Lender  or  Lenders  whose  participations  in  such  Borrowing
         constitute at least 50% by value of such  Borrowing,  that by reason of
         circumstances  affecting the London  interbank  market or the Euro-zone
         interbank market, as applicable:

                           (A) deposits in the applicable Alternate Currency the
         same period as such  Interest  Period will not be readily  available to
         them in the London interbank market or the Euro-zone  interbank market,
         as applicable, in sufficient amounts in the ordinary course of business
         to fund their  respective  Loans in such  Borrowing  for such  Interest
         Period; or

                           (B) while such deposits are so available, the cost of
         such  deposits  exceeds  the  applicable  LIBO  Rate as  determined  in
         relation to such Borrowing for such Interest Period; or

                  (ii) the Administrative Agent shall have received notification
         from any Lender (an "Affected  Lender") that by reason of any change in
         or  the  introduction  (or  re-introduction)  of or any  change  in the
         interpretation,  administration  or  application  of applicable  law or
         regulation  (in each such case after the date hereof or, if later,  the
         date on which the Affected  Lender became a part to this  Agreement) it
         is  unable  to fund its Loan in such  Borrowing  during  such  Interest
         Period by deposit(s) in the applicable  Alternate  Currency obtained in
         the London  interbank  market or the  Euro-zone  interbank  market,  as
         applicable, in the ordinary course of business;

         the  Administrative  Agent shall  promptly give written  notice of such
         determination or notification to the Company and each of the Lenders.

                  (c) After the giving of any notice by the Administrative Agent
pursuant to Section  2.11(b) to the effect that it has received  notification in
accordance with Section 2.11(b)(i)(A) or 2.11(b)(ii),  no Lender or, as the case
may be, no Affected  Lender shall be obliged to  participate in the Borrowing to
which  such   notification   relates  unless  such  Borrowing  is  already  then
outstanding.  The giving of any notice by the  Administrative  Agent pursuant to
Section 2.11(b)(i)(B) shall not relieve any Lender of any obligation it may have
under this  Agreement to make a Loan  (including  any Loan for which a Borrowing
Request was given prior to such notice by the Administrative Agent).

                  (d)  During  the  period of 15 days  after  the  giving of any
notice  by  the   Administrative   Agent  pursuant  to  Section   2.11(b),   the
Administrative  Agent (in consultation  with the Lenders or the Affected Lender)
shall  negotiate  with the  Company in good  faith  with a view to  ascertaining
whether a substitute  basis (a ASubstitute  Basis@) may be agreed for the making
of further  Borrowings and/or the maintaining of any existing  Borrowings by the
Lenders or such Affected Lender (as the case may be) to which such notice by the
Administrative  Agent  related for the Interest  Period(s)  applicable  to those
Borrowings.  If a  Substitute  Basis  is  agreed  by all the  Lenders  or by the
Affected  Lender  (as the  case  may  be) and the  Company  it  shall  apply  in
accordance  with its terms from the  commencement of such Interest  Period.  The
Administrative  Agent shall not agree to any  Substitute  Basis on behalf of any
Lender or Affected  Lender  without the prior consent of that Lender or Affected
Lender (as the case may be).

                  (e) If a Substitute  Basis is not so agreed by the Company and
all the Lenders or the  Affected  Lender (as the case may be) by the end of such
15 day period, each Lender's or Affected Lender's then existing Loan or Loans to
which the notice by the Administrative  Agent related shall bear interest during
the current Interest Period relative thereto at the rate which is the sum of (a)
the per annum rate certified by such Lender or Affected Lender to be its cost of
funds (from such sources as it may  reasonably  select out of those sources then
available  to it) for  such  Interest  Period  in  relation  to  such  Borrowing
multiplied by the Reserve Rate, plus (b) the Associated Costs Rate, plus (c) the
Applicable Rate.

                  (f) So long as any  Substitute  Basis is in  force or  Section
2.11(e) shall apply in relation to any Borrowing,  the Administrative  Agent, in
consultation  with the Company and each  Lender  (or,  if  applicable,  Affected
Lender) shall from time to time, but not less often then monthly, review whether
or not the  circumstances  referred to in Section  2.11(b)  still prevail with a
view to returning to the normal interest provisions of this Agreement.

         SECTION 2.12.  Illegality;  Increased  Costs.  (a) If any Change in Law
shall make it unlawful or  impossible  for any Lender to make,  maintain or fund
its  Loans,  such  Lender  shall  so  notify  the   Administrative   Agent,  the
Administrative  Agent shall immediately give notice thereof to the other Lenders
and to the  Company,  whereupon  until such Lender  notifies the Company and the
Administrative  Agent that the  circumstances  giving rise to such suspension no
longer  exist,  the  obligation  of such  Lender  to make  such  Loans  shall be
suspended.  If such Lender shall determine that it may not lawfully  continue to
maintain and fund any of its outstanding  Loans to maturity and shall so specify
in such notice,  the applicable  Borrower shall  immediately  prepay in full the
then  outstanding  principal  amount  of such  Loan  together  with the  accrued
interest thereon.

                  (b) If any  Change  in  Law,  including,  without  limitation,
reserve  requirements  imposed  by the  European  System of  Central  Banks with
respect  to the Euro or the  National  Currencies  on or after  January 1, 1999,
shall:

                  (i) impose,  modify or deem  applicable  any reserve,  special
         deposit or similar  requirement against assets of, deposits with or for
         the  account  of, or credit  extended  by, any Lender  (except any such
         reserve  requirement  reflected in the  Adjusted CD Rate,  the Adjusted
         Eurodollar  LIBO Rate,  the  Adjusted  Sterling  LIBO Rate or  Adjusted
         EURIBOR); or

                  (ii) impose on any Lender,  the London interbank market or the
         Euro-zone interbank market any other condition affecting this Agreement
         or any Loans made by such Lender;

and the result of any of the  foregoing  shall be to  increase  the cost to such
Lender of making or maintaining  any Loan (or of  maintaining  its obligation to
make any such  Loan) or to  increase  the cost to such  Lender or to reduce  the
amount of any sum received or  receivable by such Lender  hereunder  (whether of
principal, interest or otherwise), then the applicable Borrower will pay to such
Lender such additional amount or amounts as will compensate such Lender for such
additional costs incurred or reduction suffered.

                  (c) If any Lender  determines that any Change in Law regarding
capital requirements has or would have the effect of reducing the rate of return
on such Lender's capital or on the capital of such Lender's holding company,  if
any, as a  consequence  of this  Agreement or the Loans made by such Lender to a
level below that which such Lender or such Lender's  holding  company could have
achieved but for such Change in Law (taking  into  consideration  such  Lender's
policies  and the  policies of such  Lender's  holding  company  with respect to
capital  adequacy),  then from time to time the applicable  Borrower will pay to
such Lender such additional  amount or amounts as will compensate such Lender or
such Lender's holding company for any such reduction suffered.

                  (d) A  certificate  of a Lender  setting  forth the  amount or
amounts necessary to compensate such Lender or its holding company,  as the case
may be, as specified in paragraph  (b) or (c) of this Section shall be delivered
to the applicable  Borrower and shall be conclusive  absent manifest error.  The
applicable  Borrower  shall pay such Lender the amount  shown as due on any such
certificate within 10 days after receipt thereof.

                  (e)  Failure  or  delay on the part of any  Lender  to  demand
compensation  pursuant to this  Section  shall not  constitute  a waiver of such
Lender's  right to  demand  such  compensation;  provided  that  the  applicable
Borrower  shall not be required to compensate a Lender  pursuant to this Section
for any increased  costs or reductions  incurred more than 270 days prior to the
date that such  Lender  notifies  the  applicable  Borrower of the Change in Law
giving rise to such increased costs or reductions and of such Lender's intention
to claim  compensation  therefor;  provided  further  that, if the Change in Law
giving rise to such  increased  costs or  reductions  is  retroactive,  then the
270-day  period  referred  to above  shall be  extended to include the period of
retroactive effect thereof.

         SECTION 2.13. Break Funding  Payments.  In the event of (a) the payment
of any principal of any CD Loan,  EURIBOR Loan, or LIBOR Loan, other than on the
last day of an Interest Period applicable  thereto  (including as a result of an
Event of Default), (b) the conversion of any CD Loan, EURIBOR Loan or LIBOR Loan
other than on the last day of the Interest Period  applicable  thereto,  (c) the
failure to borrow,  convert,  continue or prepay any Revolving  Loan on the date
specified in any notice  delivered  pursuant hereto  (regardless of whether such
notice may be  revoked  under  Section  2.08(b)  and is  revoked  in  accordance
therewith),  or (d) the  assignment of any CD Loan,  EURIBOR Loan, or LIBOR Loan
other than on the last day of the Interest Period applicable thereto as a result
of a request by the Company  pursuant to Section 2.16,  then, in any such event,
the applicable  Borrower  shall  compensate  each Lender for the loss,  cost and
expense  attributable to such event.  In the case of a CD Loan,  EURIBOR Loan or
LIBOR Loan,  such loss, cost or expense to any Lender shall be deemed to include
an amount  determined by such Lender to be the excess, if any, of (i) the amount
of interest  which would have accrued on the  principal  amount of such Loan had
such event not  occurred,  at the  Adjusted  CD Rate (in the case of a CD Loan),
Adjusted EURIBOR (in the case of a EURIBOR Loan) or the Adjusted Eurodollar LIBO
Rate or the Adjusted Sterling LIBO Rate, as applicable,  (in the case of a LIBOR
Loan),  that would have been  applicable  to such Loan,  for the period from the
date of such event to the last day of the then current  Interest Period therefor
(or,  in the case of a failure to borrow,  convert or  continue,  for the period
that would have been the Interest Period for such Loan), over (ii) the amount of
interest  which  would  accrue on such  principal  amount for such period at the
interest rate which such Lender would bid were it to bid, at the commencement of
such period,  for Dollar  deposits of a comparable  amount and period from other
banks in the  eurodollar  market.  A certificate of any Lender setting forth any
amount or amounts  that such  Lender is  entitled  to receive  pursuant  to this
Section  shall be delivered to the  applicable  Borrower and shall be conclusive
absent manifest error. The applicable  Borrower shall pay such Lender the amount
shown as due on any such certificate within 10 days after receipt thereof.

         SECTION 2.14.  Taxes.  (a) Any and all payments by or on account of any
obligation of any Borrower hereunder shall be made free and clear of and without
deduction  for any  Indemnified  Taxes  or  Other  Taxes;  provided  that if any
Borrower shall be required to deduct any  Indemnified  Taxes or Other Taxes from
such payments,  then (i) the sum payable shall be increased as necessary so that
after  making  all  required  deductions  (including  deductions  applicable  to
additional sums payable under this Section) the Administrative Agent or a Lender
(as the case may be) receives an amount equal to the sum it would have  received
had no such deductions  been made, (ii) the applicable  Borrower shall make such
deductions and (iii) the applicable  Borrower shall pay the full amount deducted
to the relevant Governmental Authority in accordance with applicable law.

                  (b) In addition,  each  Borrower  shall pay any Other Taxes to
the relevant Governmental Authority in accordance with applicable law.

                  (c) Each Borrower shall indemnify the Administrative Agent and
each Lender,  within 10 days after written demand therefor,  for the full amount
of any Indemnified Taxes or Other Taxes paid by the Administrative Agent or such
Lender,  as the case may be, on or with  respect to any payment by or on account
of any obligation of such Borrower  hereunder  (including  Indemnified  Taxes or
Other Taxes imposed or asserted on or attributable to amounts payable under this
Section) and any penalties,  interest and reasonable  expenses arising therefrom
or with respect thereto,  whether or not such  Indemnified  Taxes or Other Taxes
were  correctly  or legally  imposed or  asserted by the  relevant  Governmental
Authority. A certificate as to the amount of such payment or liability delivered
to the applicable Borrower by a Lender or by the Administrative Agent on its own
behalf or on behalf of a Lender, shall be conclusive absent manifest error.

                  (d) As soon as  practicable  after any payment of  Indemnified
Taxes or Other Taxes by a Borrower to a Governmental  Authority,  the applicable
Borrower shall deliver to the  Administrative  Agent the original or a certified
copy of a receipt issued by such Governmental Authority evidencing such payment,
a copy of the return  reporting  such payment or other  evidence of such payment
reasonably satisfactory to the Administrative Agent.

                  (e) As of the date on which any Lender becomes a party hereto,
such Lender  confirms  that with respect to its Loans to a United  States person
(within  the  meaning of Section  7701(a)(30)  of the Code),  it is either (i) a
corporation  organized  under the laws of the  United  States of  America or any
state thereof, entitled to complete exemption from United States withholding tax
imposed on or with respect to any  payments,  including  fees,  to be made to it
pursuant to this Agreement,  or (ii) entitled to complete  exemption from United
States withholding tax on interest imposed on or with respect to any payments of
interest to be made pursuant to this Agreement (A) under an applicable provision
of a U.S.  Double  Taxation  Treaty,  (B) because it is acting through a branch,
agency or office in the United  States of America and any payment to be received
by it hereunder is effectively  connected with a trade or business in the United
States of America, or (C) because it is a recipient of portfolio interest within
the meaning of Section  871(h) or 881(c) of the Code.  Such  Lender,  as of such
date,  also  confirms  that with  respect  to its Loans  (or  interest  or other
payments relating thereto)  regarding which the U.K. Tax Act could reasonably be
expected to result in withholding tax  requirements  under the U.K. Tax Act (but
for the applicable Lender qualifying for the immediately  following  exemptions)
it is either (x) a bank as defined in Section 840A of the U.K.  Tax Act,  which,
for the  purposes  of  Sections  349 and 212 of the U.K.  Tax Act, is within the
charge  to  United  Kingdom  corporation  tax as  regards,  and is  beneficially
entitled to, any interest  received by it under this Agreement,  except that, if
that Section is repealed,  modified,  extended or re-enacted, the Administrative
Agent  may at any time and from  time to time  (acting  reasonably)  amend  this
definition  to reflect  such  repeal,  modification,  extension  or enactment by
giving notice of the amended definition to the Company, or (y) a person carrying
on a bona fide banking  business who is resident (as such term is defined in the
appropriate  U.K.  Double  Taxation  Treaty) in a country  with which the United
Kingdom has an appropriate  U.K. Double Taxation Treaty giving residents of that
country full  exemption  from United  Kingdom  taxation on interest and does not
carry on business in the United Kingdom through a permanent  establishment  with
which the indebtedness  under this Agreement in respect of which the interest is
paid is effectively  connected.  Each Lender that is not a corporation organized
under the laws of the  United  States of  America  or any  state  thereof  shall
provide to the Company and the Administrative Agent on or before the date of any
payment  by any  Borrower  hereunder,  or on the  date  of its  delivery  of the
Assignment  and  Acceptance  pursuant to which it becomes a Lender,  and at such
other  times  as  required  by  United  States  law  or as  the  Company  or the
Administrative  Agent  shall  reasonably  request,  two  accurate  and  complete
original  signed  copies of either (A)  Internal  Revenue  Service Form 4224 (or
successor form)  certifying that all payments to be made to it hereunder will be
effectively  connected  to a United  States  trade or  business  (the "Form 4224
Certification"),  or (B) Internal  Revenue Service Form 1001 (or successor form)
certifying  that it is entitled to the benefit of a provision  of a U.S.  Double
Taxation Treaty which completely  exempts from United States withholding tax all
payments of interest to be made to it hereunder (the "Form 1001 Certification").
In  addition,  each  Lender  agrees  that if it  previously  filed  a Form  4224
Certification it will deliver to the Company and the Administrative  Agent a new
Form 4224 Certification prior to the first payment date occurring in each of its
subsequent  taxable  years (or such other date as may be required in  compliance
with applicable law); and if it previously filed a Form 1001  Certification,  it
will  deliver to the Company and the  Administrative  Agent a new  certification
prior to the first payment date falling in the third year following the previous
filing  of  such  certification  (or  such  other  date  as may be  required  in
compliance with applicable law).

Each Lender also agrees to deliver to the Company and the  Administrative  Agent
such  other or  supplemental  forms as may at any time be  required  in order to
confirm or maintain in effect its entitlement to exemption from United States or
United  Kingdom  withholding  tax on any payments  hereunder,  provided that the
circumstances  of the Lender at the relevant time and applicable  laws permit it
to do so. Except as provided  immediately  below, if a Lender is organized under
the laws of a  jurisdiction  outside the United  States of  America,  unless the
Company and the Administrative  Agent have received a Form 1001 Certification or
Form 4224  Certification,  reasonably  satisfactory  to them indicating that all
payments of  interest,  to be made to such Lender  hereunder  are not subject to
United States  withholding  tax, the Company shall be entitled to withhold taxes
from  such  payments  at the  applicable  statutory  rate,  provided  that  such
withholding  shall not  increase  the amount of payments for the account of such
Lender to be made by the Company  pursuant to  Subsection  2.14(a).  If a Lender
determines,  as a result of any change in either (i) applicable law,  regulation
or treaty,  or in any official  application  thereof or (ii) its  circumstances,
that it is unable to submit  any form or  certificate  that it is  obligated  to
submit  pursuant to this  Section,  or that it is required to withdraw or cancel
any such form or certificate previously submitted,  it shall promptly notify the
Company  and the  Administrative  Agent of such  fact and the  Company  shall be
entitled to withhold taxes from such payments at the applicable  statutory rate,
it being understood that such withholding  shall increase the amount of payments
for the  account of such  Lender to be made by the  Company  pursuant to Section
2.14(a).  Each Lender  agrees to  indemnify  and hold the  Administrative  Agent
harmless from any United States or United Kingdom taxes, penalties, interest and
other expenses, costs and losses incurred or payable by the Administrative Agent
(i) as a result of such Lender's  failure to submit any form or certificate that
it is  required to provide  pursuant to this  Section or (ii) as a result of the
Administrative  Agent's  reliance  on any such form or  certificate  which  such
Lender has  provided  to it  pursuant  to this  Section.  Each Person that shall
become a Lender or a  Participant  pursuant  to Section  10.04  shall,  upon the
effectiveness of the related transfer,  be required to provide all of the forms,
certifications and statements  required pursuant to this Section,  provided that
in the case of a Participant  the obligations of such  Participant  shall be the
same as if it were a Lender, except that such Participant shall furnish all such
required  forms,  certifications  and  statements  to the Lender  from which the
related  participation  shall have been  purchased and such Lender shall provide
such forms to the Company and the Administrative Agent.

         SECTION  2.15.  Payments  Generally;  Pro Rata  Treatment;  Sharing  of
Set-offs.  (a) Each Borrower  shall make each payment  required to be made by it
hereunder  (whether of  principal,  interest,  fees or of amounts  payable under
Section 2.12, 2.13 or 2.14, or otherwise)  prior to 12:00 noon, New York City or
London  time,  as  applicable,  on the date when due, in  immediately  available
funds, without set-off or counterclaim.  Any amounts received after such time on
any date may, in the discretion of the  Administrative  Agent, be deemed to have
been received on the next  succeeding  Business Day for purposes of  calculating
interest  thereon.  All such  payments  shall be made to the  applicable  Agency
Account  for the  account of the  Lenders,  except  that  payments  pursuant  to
Sections  2.12,  2.13,  or 2.14 and 10.03 shall be made  directly to the Persons
entitled thereto.  The  Administrative  Agent shall distribute any such payments
received by it for the account of any other Person to the appropriate  recipient
promptly  following receipt thereof.  If any payment hereunder shall be due on a
day that is not a Business  Day,  the date for payment  shall be extended to the
next succeeding Business Day, and, in the case of any payment accruing interest,
interest thereon shall be payable for the period of such extension. All payments
hereunder shall be made in Dollars, except that with respect to any Loan that is
denominated  in an Alternate  Currency,  all payments of principal  and interest
with respect to such Loan shall be made in the Alternate  Currency in which such
Loan  is  denominated;   provided,  however,  that  with  respect  to  any  Loan
denominated  in a National  Currency,  all payments with respect  thereto may be
made in Euros in accordance with Section 1.05.

                  (b) If at any time  insufficient  funds  are  received  by and
available  to the  Administrative  Agent to pay fully all amounts of  principal,
interest  and fees then due  hereunder,  such  funds  shall be  applied  towards
payment of  interest  and fees then due  hereunder,  ratably  among the  parties
entitled thereto in accordance with the amounts of interest and fees then due to
such parties.

                  (c) If any Lender shall, by exercising any right of set-off or
counterclaim  or  otherwise,  obtain  payment in respect of any  principal of or
interest on any of its Loans  resulting  in such Lender  receiving  payment of a
greater  proportion  of the aggregate  amount of its Loans and accrued  interest
thereon  than the  proportion  received  by any other  Lender,  then the  Lender
receiving  such  greater  proportion  shall  purchase  (for cash at face  value)
participations in the Loans of other Lenders to the extent necessary so that the
benefit  of all  such  payments  shall  be  shared  by the  Lenders  ratably  in
accordance  with the  aggregate  amount of principal of and accrued  interest on
their  respective  Loans;  provided  that  (i) if any  such  participations  are
purchased  and  all or any  portion  of  the  payment  giving  rise  thereto  is
recovered,  such  participations  shall  be  rescinded  and the  purchase  price
restored  to the  extent  of such  recovery,  without  interest,  and  (ii)  the
provisions of this paragraph shall not be construed to apply to any payment made
by a Borrower  pursuant  to and in  accordance  with the  express  terms of this
Agreement  or  any  payment  obtained  by a  Lender  as  consideration  for  the
assignment of or sale of a participation  in any of its Loans to any assignee or
participant, other than to a Borrower or any Subsidiary or Affiliate thereof (as
to which the provisions of this paragraph shall apply).  Each Borrower  consents
to the  foregoing  and  agrees,  to the  extent it may  effectively  do so under
applicable  law,  that any Lender  acquiring  a  participation  pursuant  to the
foregoing  arrangements may exercise against such Borrower rights of set-off and
counterclaim with respect to such  participation as fully as if such Lender were
a direct creditor of such Borrower in the amount of such participation.

                  (d) Unless the Administrative Agent shall have received notice
from  a  Borrower  prior  to  the  date  on  which  any  payment  is  due to the
Administrative Agent for the account of the Lenders hereunder that such Borrower
will not make  such  payment,  the  Administrative  Agent  may  assume  that the
applicable  Borrower has made such payment on such date in  accordance  herewith
and may, in reliance upon such assumption,  distribute to the Lenders the amount
due.  In such  event,  if the  applicable  Borrower  has not in fact  made  such
payment,   then  each  of  the  Lenders   severally   agrees  to  repay  to  the
Administrative  Agent  forthwith  on demand  the amount so  distributed  to such
Lender with  interest  thereon,  for each day from and  including  the date such
amount  is  distributed  to it to but  excluding  the  date  of  payment  to the
Administrative  Agent,  at the greater of the Federal Funds Effective Rate and a
rate determined by the Administrative  Agent in accordance with banking industry
rules on interbank compensation.

                  (e) If any Lender  shall fail to make any payment  required to
be made by it pursuant to Section  2.04(b) or 2.15(d),  then the  Administrative
Agent may, in its discretion  (notwithstanding  any contrary  provision hereof),
apply  any  amounts  thereafter  received  by the  Administrative  Agent for the
account of such Lender to satisfy such Lender's  obligations under such Sections
until all such unsatisfied obligations are fully paid.

         SECTION 2.16.  Mitigation  Obligations;  Replacement of Lenders. (a) If
any Lender  requests  compensation  under  Section  2.12,  or if any Borrower is
required  to pay  any  additional  amount  to  any  Lender  or any  Governmental
Authority  for the  account of any Lender  pursuant to Section  2.14,  then such
Lender shall use reasonable  efforts to designate a different lending office for
funding or booking its Loans  hereunder or to assign its rights and  obligations
hereunder to another of its offices, branches or Affiliates, if, in the judgment
of such Lender,  such  designation or assignment  (i) would  eliminate or reduce
amounts  payable  pursuant to Section  2.12 or 2.14,  as the case may be, in the
future  and (ii)  would not  subject  such  Lender to any  unreimbursed  cost or
expense and would not otherwise be disadvantageous to such Lender. Each Borrower
hereby agrees to pay all reasonable  costs and expenses  incurred by such Lender
in connection with any such designation or assignment.

                  (b) If any Lender requests compensation under Section 2.12, or
if any  Borrower is required to pay any  additional  amount to any Lender or any
Governmental  Authority for the account of any Lender  pursuant to Section 2.14,
or if any Lender  defaults in its obligation to fund Loans  hereunder,  then the
Company may, at its sole expense and effort,  upon notice to such Lender and the
Administrative  Agent,  require  such  Lender to assign  and  delegate,  without
recourse  (in  accordance  with and  subject to the  restrictions  contained  in
Section 10.04),  all its interests,  rights and obligations under this Agreement
to an assignee that shall assume such obligations (which assignee may be another
Lender,  if a Lender  accepts such  assignment);  provided  that (i) the Company
shall have received the prior written consent of the Administrative Agent, which
consent shall not unreasonably be withheld, (ii) such Lender shall have received
payment of an amount equal to the  outstanding  principal of its Loans,  accrued
interest  thereon,  accrued fees and all other amounts  payable to it hereunder,
from the  assignee  (to the extent of such  outstanding  principal  and  accrued
interest  and fees) or the Company (in the case of all other  amounts) and (iii)
in the case of any such assignment resulting from a claim for compensation under
Section  2.12 or payments  required to be made  pursuant to Section  2.14,  such
assignment will result in a reduction in such compensation or payments. A Lender
shall not be required  to make any such  assignment  and  delegation  if,  prior
thereto, as a result of a waiver by such Lender or otherwise,  the circumstances
entitling the Company to require such assignment and delegation cease to apply.

         SECTION 2.17.  Foreign  Available Amount  Designation.  Once per Fiscal
Quarter,  the Company,  may, at its sole option,  designate or  redesignate  the
amount of the Foreign  Available  Amount by  delivering a written  notice to the
Administrative  Agent  not less than five  Business  Days  prior to the date the
Company proposes that the newly designated Foreign Available Amount would become
effective;  provided,  that no such designation of the Foreign  Available Amount
may occur if a Default exists or if the sum of the Revolving  Credit  Exposures,
with respect to the Foreign Subsidiary Borrowers or the Company and the Domestic
Subsidiary  Borrowers,  as  applicable,  would,  after  giving  effect  to  such
designation  and any  concurrent  payments  on such  Loans,  exceed the  Foreign
Available Amount or the Domestic Available Amount, respectively.

         SECTION 2.18.  Extension of Stated Revolving Loan Maturity Date. (a) No
earlier  than 90 days and no  later  than 60 days  prior to the then  applicable
Revolving Loan Maturity Date, the Company may,  subject to  satisfaction  of the
conditions  precedent for a Borrowing other than a Refunding Borrowing set forth
in Section 4.02,  request in writing  delivered to the  Administrative  Agent an
extension of the  Revolving  Loan  Maturity  Date for a period equal to 364 days
from the then applicable Revolving Loan Maturity Date (the "Extension Request").
The  Revolving  Loan Maturity Date shall be extended as provided in this Section
2.18 if at least the Required Lenders consent to such extension. No earlier than
30 days and no later than 25 days prior to the then  applicable  Revolving  Loan
Maturity Date, each Lender shall notify the Company and the Administrative Agent
of its  election to extend or not extend the  Revolving  Loan  Maturity  Date as
requested in such Extension  Request.  If the Required  Lenders shall approve in
writing the  extension of the Revolving  Loan  Maturity  Date  requested in such
Extension  Request,  the Revolving  Loan Maturity Date shall  automatically  and
without any further action by any Person be extended for the period specified in
such  Extension  Request;  provided  that (i) each  extension  pursuant  to this
Section 2.18 shall be for a maximum of 364 days,  and (ii) the Commitment of any
Lender that does not consent in writing within 30 days after  receiving from the
Administrative Agent the applicable Extension Request (a "Non-Extending Lender")
shall,  unless earlier  terminated in accordance with this Agreement,  expire on
the Revolving Loan Maturity Date in effect on the date of such Extension Request
(such  Revolving  Loan  Maturity  Date, if any,  referred to as the  "Commitment
Expiration Date" with respect to such Non-Extending  Lender). If, within 30 days
after receiving from the Administrative  Agent the applicable Extension Request,
the Required Lenders shall not approve in writing the extension of the Revolving
Loan  Maturity  Date  requested  in an Extension  Request,  the  Revolving  Loan
Maturity  Date shall not be extended  pursuant to such  Extension  Request.  The
Administrative  Agent shall  promptly  notify (y) the Lenders and the Company of
any extension of the Revolving  Loan Maturity Date pursuant to this Section 2.18
and (z) the Company and the Lenders of any Lender which becomes a  Non-Extending
Lender.

                  (b) Loans owing to any Non-Extending  Lender on the Commitment
Expiration Date with respect to such Lender shall be repaid in full on or before
the Commitment Expiration Date.

                  (c) Each Borrower shall have the right, so long as no Event of
Default  has  occurred  and  is  then  continuing,  upon  giving  notice  to the
Administrative Agent and the Non-Extending  Lenders, to prepay in full the Loans
made to it owing to the  Non-Extending  Lenders,  together with accrued interest
thereon,  any amounts payable  pursuant to Sections 2.10,  2.12,  2.13, 2.14 and
10.03(b) and any accrued and unpaid facility fee or other amounts payable to the
Non-Extending Lenders hereunder and/or, upon giving not less than three Business
Days'  notice to the  Non-Extending  Lenders and the  Administrative  Agent,  to
cancel the whole or part of the Commitments of the Non-Extending Lenders.

                  (d)  Notwithstanding  the  foregoing,  if any Lender becomes a
Non-Extending  Lender,  the  Company  may,  at its own  expense  and in its sole
discretion and prior to the then stated  Revolving  Loan Maturity Date,  require
such Lender to transfer or assign,  in whole or in part,  without  recourse  (in
accordance  with  Section  10.04),  all or part  of its  interests,  rights  and
obligations  under this Agreement to an assignee  permitted  under Section 10.04
(provided  that the  Company  with  the full  cooperation  of such  Lender,  can
identify such an assignee that is ready, willing and able to be an assignee with
respect  thereto) which shall assume such assigned  obligations  (which assignee
may be  another  Lender,  if such  assignee  Lender  accepts  such  assignment);
provided  that (i) the assignee or the  Company,  as the case may be, shall have
paid to such Lender in immediately available funds the principal of and interest
accrued to the date of such  payment on the Loans made by it  hereunder  and all
other amounts owed to it hereunder,  including,  without limitation, any amounts
owing  pursuant to Section  10.03(b)  and any amounts  that would be owing under
said Section if such Loans were prepaid on the date of such assignment, and (ii)
such  assignment  does not conflict with any applicable law of any  Governmental
Authority. Any assignee which becomes a Lender as a result of such an assignment
made  pursuant to this  paragraph  (d) shall be deemed to have  consented to the
applicable  Extension  Request  and,  therefore,  shall  not be a  Non-Extending
Lender.

         SECTION 2.19. Addition or Termination of Subsidiary Borrowers.  So long
as no Default  exists,  the Company may from time to time provide written notice
to the  Administrative  Agent, and the  Administrative  Agent shall  immediately
thereafter  provide a copy of such notice along with a copy of all documentation
relating thereto received from the Company to each of the Lenders:

                   (a)  Designating  any  of  its  wholly  owned,   directly  or
indirectly,  Subsidiaries  organized  under  the laws of the  United  States  of
America,  any State  thereof  or the  District  of  Columbia,  as an  additional
Domestic Subsidiary Borrower and shall execute and deliver,  and cause each such
newly designated  Domestic  Subsidiary  Borrower to execute and deliver,  to the
Administrative  Agent a Joinder Agreement  (together with all documents required
to be attached thereto)  whereupon such Subsidiary shall thereafter qualify as a
Domestic Subsidiary Borrower.

                   (b)  Designating  any  of  its  wholly  owned,   directly  or
indirectly,  Subsidiaries  organized under the laws of the United Kingdom or any
Participating   Member   State  and  located  in  the  United   Kingdom  or  any
Participating  Member State, as an additional  Foreign  Subsidiary  Borrower and
shall  execute  and  deliver,  and cause  each  such  newly  designated  Foreign
Subsidiary  Borrower  to execute  and  deliver,  to the  Administrative  Agent a
Joinder Agreement  (together with all documents required to be attached thereto)
whereupon  such  Subsidiary  shall  thereafter  qualify as a Foreign  Subsidiary
Borrower;  provided,  however,  that for purposes of this Section  2.19(b),  any
Subsidiary  of  the  Company  that  is  required  by the  applicable  law of its
jurisdiction  of  organization  or  formation  to be owned by a citizen  of such
jurisdiction or Person  organized or formed under the laws of such  jurisdiction
in an amount  equal to or less than one percent of the  capital  stock or equity
interest of such  Subsidiary  and such one percent or lesser amount of ownership
does not provide for voting or  distribution  rights in excess of such ownership
percentage or otherwise  give a Controlling  interest to such Person,  then, for
purposes of this Section  2.19(b),  such Subsidiary shall be deemed to be wholly
owned by the Company.

                  (c) With respect to any Subsidiary Borrower,  that the Company
is terminating such Subsidiary's  designation as a Domestic  Subsidiary Borrower
or a  Foreign  Subsidiary  Borrower,  as  the  case  may  be,  whereupon  if all
obligations  of such  Subsidiary  Borrower to the  Administrative  Agent and the
Lenders under or in connection with this Agreement have been  indefeasibly  paid
in full pursuant to the terms hereof, such Subsidiary shall thereafter no longer
be a Subsidiary Borrower hereunder.

         SECTION 2.20. Change in Control. If a Change in Control shall occur (i)
the Company will, within ten days after the occurrence thereof, give each Lender
notice  thereof  and  shall   describe  in  reasonable   detail  the  facts  and
circumstances  giving rise  thereto and (ii) each Lender may, at any time at its
option by notice to the Borrowers and the  Administrative  Agent given not later
than 60 days after such Change in Control,  (x) terminate its Commitment,  which
Commitment shall thereupon be terminated,  and (y) by three Business Days notice
to the  Borrowers  and the  Administrative  Agent  declare  the Loans held by it
(together with accrued interest thereon) and any other amounts payable hereunder
for its  account to be, and such Loans and such other  amounts  shall  thereupon
become,  immediately due and payable without  presentment,  demand,  protest, or
other notice of any kind, all of which are hereby waived by the Borrowers.

         SECTION 2.21.  Conversion  to Term Loans.  At the option of the Company
and subject to the  satisfaction  of the  conditions  precedent  for a Borrowing
other than a Refunding  Borrowing set forth in Section 4.02, upon written notice
delivered to the Administrative  Agent no earlier than 60 days and no later than
30 days prior to the then applicable Revolving Loan Maturity Date, the aggregate
principal  amount of any Revolving Loans  remaining  outstanding at the close of
the  Administrative  Agent's  business  on the then  applicable  Revolving  Loan
Maturity Date, shall automatically  convert to Term Loans with a maturity of two
years.  Any portion of each  Lender's  Commitment  not utilized on or before the
then applicable Revolving Loan Maturity Date shall be permanently cancelled. Any
Term Loans that are prepaid may not be reborrowed.

                                   ARTICLE III

                         Representations and Warranties

         To induce  the  Lenders to enter  into this  Agreement  and to make the
Loans,  each  Borrower   represents  and  warrants  (such   representations  and
warranties  to  survive  any  investigation  and the making of the Loans) to the
Lenders and the Administrative Agent that:

         SECTION  3.01.   Corporate  Existence  and  Power.  The  Company  is  a
corporation duly  incorporated,  validly existing and in good standing under the
laws of the State of Delaware. Each Material Subsidiary organized under the laws
of the United States of America, any State thereof, or the District of Columbia,
is a corporation duly  incorporated,  validly existing and in good standing (or,
if such  Subsidiary  is a limited  liability  company,  is a  limited  liability
company duly formed,  validly  existing and in good standing)  under the laws of
its  jurisdiction of  incorporation,  organization  or formation.  Each Material
Subsidiary  organized under the laws of a jurisdiction  other than United States
of America,  any State  thereof,  or the  District of Columbia is a company duly
formed and validly existing under the laws of its jurisdiction of formation. The
Company and each  Material  Subsidiary  has all  requisite  corporate or limited
liability  company  power  and  all  material  governmental  licenses,  permits,
authorizations,  qualifications, consents and approvals required to carry on its
business as now conducted  which, if not obtained,  could reasonably be expected
to have a Material Adverse Effect.

         SECTION   3.02.   Corporate   and   Governmental   Authorization;    No
Contravention.  The execution, delivery and performance of this Agreement by the
Company and each Subsidiary  Borrower are within each such Borrower's  corporate
or limited liability company powers,  have been duly authorized by all necessary
corporate or limited liability company action,  require no approval of or filing
with any  governmental  body,  agency or  official or any other  Person,  do not
conflict  with,  contravene  or  constitute  a default  under any  provision  of
applicable law or regulation or of the  certificate of  incorporation,  by-laws,
articles of  association or memorandum of association of such Borrower or of any
agreement,  judgment, injunction, order, decree or other instrument binding upon
such Borrower  unless such conflict  could not  reasonably be expected to have a
Material  Adverse  Effect,  and will not result in the creation or imposition of
any mortgage,  security  interest or other lien or  encumbrance  on any asset or
revenues of such Borrower or any of its Subsidiaries.

         SECTION 3.03. Binding Effect. This Agreement constitutes a legal, valid
and  binding  agreement  of each of the  Company  and each  Subsidiary  Borrower
enforceable against each Borrower in accordance with its terms.

         SECTION 3.04.  Financial Information.

         (a) The consolidated  balance sheet of the Company and its Consolidated
Subsidiaries as of December 31, 1997, and the related consolidated statements of
income, retained earnings and cash flows for the year then ended, reported on by
Arthur Andersen L.L.P. and set forth in the Company's 1997 Annual Report, a copy
of  which  has  been  delivered  to  each of the  Lenders,  fairly  present,  in
conformity with GAAP, the consolidated financial position of the Company and its
Consolidated  Subsidiaries  as of such date and their  consolidated  results  of
operations and cash flows for such year.

         (b) the unaudited  consolidated statement of financial condition of the
Company and its Consolidated Subsidiaries at September 30, 1998, and the related
consolidated  statements  of income and retained  earnings and cash flows of the
Company and its  Consolidated  Subsidiaries for the nine months ending September
30, 1998, heretofore furnished to the Lenders present fairly, in conformity with
GAAP, the  consolidated  financial  condition of the Company at the date of said
statements for said periods,  subject to year-end audit  adjustments in the case
of such unaudited statements.

         (c) At the Effective Date, there has been no material adverse change in
the  business,  assets,  operations,   prospects  or  condition,   financial  or
otherwise,  of the Company and its Consolidated  Subsidiaries,  taken as a whole
since  September 30, 1998,  including with regard thereto the selected pro forma
financial  information  dated as of and for the nine months ended  September 30,
1998,  set forth in the  Company's  S-4 filed with the SEC, and  effective as of
January 27, 1999.

         SECTION 3.05. Litigation.  Except as may have been disclosed in writing
to the Lenders prior to the signing hereof, there is no material action, suit or
proceeding pending,  or to the knowledge of the Company  threatened,  against or
affecting  the Company or any  Subsidiary  before any court or arbitrator or any
governmental  body,  agency or official  which could  reasonably  be expected to
result in a Material Adverse Effect.

         SECTION 3.06.  Compliance with ERISA.

         (a) Neither the Company nor any ERISA Affiliate has failed to comply in
any material  respect with the  applicable  provisions of ERISA and the Code and
the regulations promulgated thereunder (including, without limitation,  sections
4068, 4069 and 4212 of ERISA),  where such failure could  reasonably be expected
to result in a Material Adverse Effect.

         (b)  Other  than  premiums  to the PBGC due in the  normal  course,  no
liability to the PBGC (with respect to which the Company or any ERISA  Affiliate
is delinquent)  has been incurred and remains  unsatisfied or is expected by the
Company to be  incurred  with  respect  to any Plan by the  Company or any ERISA
Affiliate  which could  reasonably  be expected to result in a Material  Adverse
Effect.

         (c)  Neither  the  Company  nor any ERISA  Affiliate  is  obligated  to
contribute  to, or has  incurred a  withdrawal  liability  with  respect to, any
Multiemployer  Plan in an amount that would be materially adverse to the Company
and its Subsidiaries taken as a whole.

         (d) Full  payment has been made of all amounts  that the Company or any
ERISA  Affiliate  is  required  under  the  terms of each  Plan to have  paid as
contributions  to such Plan as of the last day of the most recent fiscal year of
such Plan  ended  prior to the date  hereof  (or will be made  within the period
described in Section 404 of the Code) and no accumulated  funding deficiency (as
defined in Section  302 of ERISA and  Section  412 of the Code),  whether or not
waived, exists with respect to any Plan. Each Plan satisfies the minimum funding
standard of Section 412 of the Code.

         (e) The amount of Benefit Liabilities under each Plan, determined as of
the end of the  Company's  most  recently  ended  fiscal  year (on the  basis of
assumptions  prescribed  by the PBGC for  purposes of Section 4044 of ERISA) did
not exceed the current  value of the assets of such Plans  determined as of such
date in an amount that,  individually  or in the aggregate  with such amount for
all Plans, exceeds $25,000,000.

         SECTION 3.07.  Environmental  Matters. The Company and each Subsidiary,
and to the  best of the  Company's  knowledge,  any  former  subsidiary  and any
predecessor in interest of the Company or of any Subsidiary, and with respect to
all of the Property of the Company and its Subsidiaries, and each of the plants,
sites and  facilities  presently or formerly  owned,  operated,  controlled,  or
leased  by the  Company  or  any of its  Subsidiaries,  has  complied  with  all
applicable Environmental Laws during the period such Subsidiary,  plant, site or
facility was owned, operated,  controlled or leased by the Company or any of its
Subsidiaries, except in any such case, where such failure to so comply could not
reasonably be expected to have a Material  Adverse  Effect.  Neither the Company
nor any of its Subsidiaries has received any notice of, or has knowledge of, any
actual or threatened  claim,  legal  proceeding or  investigation  regarding the
Company or any of its Subsidiaries,  or any of the respective  plants,  sites or
facilities currently or formerly owned, operated, leased or controlled by any of
them,  related to Environmental Laws which alone or together with all other such
matters  known to the Company  could  reasonably  be expected to have a Material
Adverse Effect.

         SECTION 3.08.  Taxes. The Company and its  Subsidiaries  have filed all
United  States  Federal  income tax returns and all other  material  tax returns
which are  required to be filed by them and have paid all taxes due  pursuant to
such  returns or  pursuant  to any  assessment  received  by the  Company or any
Subsidiary,  except such taxes or assessments, if any, as are being contested in
good faith by appropriate proceedings. The charges, accruals and reserves on the
books of the  Company  and its  Subsidiaries  in respect  of taxes  are,  in the
opinion of the Company, adequate.

         SECTION  3.09.  Investment  Company  Act.  None of the  Borrowers is an
investment  company within the meaning of the Investment Company Act of 1940, as
amended,  or directly  or  indirectly  controlled  by or acting on behalf of any
Person which is an investment company, within the meaning of such Act.

         SECTION 3.10. Public Utility Holding Company Act. None of the Borrowers
is a "public utility company,  or an "affiliate," or a "subsidiary  company of a
"public  utility  company,"  or a  "holding  company,"  or an  "affiliate"  or a
"subsidiary  company" of a "holding  company" or of a "subsidiary  company" of a
"holding  company,"  as such terms are  defined in the  Public  Utility  Holding
Company Act of 1935, as amended.

         SECTION  3.11.  Use of Proceeds.  No portion of the Loans will be used,
directly or indirectly,  (a) to purchase or carry any Margin Stock, (b) to repay
or otherwise  refinance  indebtedness  of any  Borrower  incurred to purchase or
carry any Margin Stock, or (c) to extend credit for the purpose of purchasing or
carrying any Margin Stock.

         SECTION 3.12. Disclosure.  The Company has disclosed to the Lenders all
agreements,  instruments and corporate or other  restrictions to which it or any
of its Material  Subsidiaries  is subject,  and all other  matters  known to it,
that,  individually or in the aggregate,  could reasonably be expected to result
in a Material Adverse Effect. None of the other reports,  financial  statements,
certificates  or other  information  furnished by or on behalf of the Company or
its  Material  Subsidiaries  to  the  Administrative  Agent  or  any  Lender  in
connection  with the  negotiation of this  Agreement or delivered  hereunder (as
modified  or  supplemented  by other  information  so  furnished)  contains  any
material  misstatement  of fact or omits to state any material fact necessary to
make the statements  therein, in the light of the circumstances under which they
were made, not misleading;  provided that,  with respect to projected  financial
information, each Borrower represents only that such information was prepared in
good faith based upon assumptions believed to be reasonable at the time.

         SECTION  3.13.  Year 2000  Compliance.  The Company  believes  that any
reprogramming  required to permit the proper  functioning,  in and following the
year 2000, of (a) the Company's, or any Material Subsidiary's,  computer systems
and  (b)  equipment  containing  embedded  microchips   (including  systems  and
equipment  supplied  by others  or with  which the  Company's,  or any  Material
Subsidiary's,  systems  interface)  and the  testing  of all  such  systems  and
equipment,  as  so  reprogrammed,   to  the  extent  necessary  to  prevent  any
significant  disruptions  to the business and  operations of the Company and its
Subsidiaries on a consolidated  basis,  will be completed by September 30, 1999.
The cost to the Company and its Material  Subsidiaries of such reprogramming and
testing  and of the  reasonably  foreseeable  consequences  of year  2000 to the
Company (including, without limitation,  reprogramming errors and the failure of
others'  systems or  equipment)  will not result in a Default or other  event or
circumstance  that could  reasonably  be  expected  to have a  Material  Adverse
Effect.

         SECTION 3.14.  Material  Subsidiaries.  As of the Effective  Date,  the
Subsidiaries  of the Company  that qualify as Material  Subsidiaries  under this
Agreement and that are not Subsidiary Borrowers are those Subsidiaries listed on
Schedule 3.14 attached hereto.

make,  convert or continue a Loan on the occasion of any Borrowing is subject to
the satisfaction of the following conditions:

Borrowing.   On  the  occasion  of  any   Refunding   Borrowing,   each  of  the
representations  and  warranties of the  Borrowers set forth in this  Agreement,
other than the  representations  and warranties  set forth in Sections  3.04(c),

each Borrower on the date thereof as to the matters specified in paragraphs (a),
(b), (c) and (d) of this Section.


                                    ARTICLE V

                              Affirmative Covenants

                  Until the Commitments  have expired or been terminated and the
principal of and interest on each Loan and all fees payable hereunder shall have

or any officer or director of a Subsidiary  Borrower obtaining  knowledge of the
occurrence of any Default,  a certificate of a Financial  Officer of the Company
setting  forth the  details  thereof  and the action  which the  Company or such
Subsidiary  Borrower,  as the case may be, is taking  or  proposes  to take with
respect thereto;

         (f)  promptly  upon the  mailing  thereof  to the  shareholders  of the

         (h) if and when the  Company  or any  ERISA  Affiliate  (i) gives or is
required  to give  notice to the PBGC of any  "reportable  event" (as defined in
Section 4043 of ERISA) with respect to any Plan which might  constitute  grounds
for a termination  of such Plan under Title IV of ERISA,  or knows that the plan

required to be given to the PBGC;  (ii)  receives  notice of complete or partial

         (i) from time to time,  upon receiving from the Lenders such assurances

information  regarding  the  performance  of  this  Agreement  or the  financial
position  or business  of any  Borrower,  as the  Administrative  Agent,  at the
request of any Lender, may reasonably request.

         SECTION  5.02.   Payment  of  Taxes.   Pay,  will  cause  each  of  its
Subsidiaries  to pay, all material  taxes,  assessments  and other  governmental
charges  imposed upon it or any of its Properties or assets or in respect of any
of its  franchises,  business,  income or profits before any penalty or interest
accrues thereon, and all material claims (including,  without limitation, claims
for labor, services,  materials and supplies) for sums which have become due and
payable and which by law have or might become a Lien upon any of its  Properties
or assets,  non-payment of which could reasonably be expected to have a Material
Adverse Effect,  provided that no such tax, assessment,  charge or claim need be
paid if being  contested  in good  faith  by  appropriate  proceedings  promptly
initiated  and  diligently  conducted  so long as no Lien  has  attached  to any
Property of the Company or its Subsidiaries as a result thereof.

         SECTION 5.03.  Insurance.  Maintain,  or cause to be  maintained,  with
financially  sound  and  reputable  insurers,  insurance  with  respect  to  its
Properties  and business  and the  Properties  and business of its  Subsidiaries
against loss or damage of the kinds  customarily  insured against by corporation
of established  reputation engaged in the same or similar business and similarly
situated,  of such types and in such amounts as are  customarily  carried  under
similar  circumstances by such other corporations;  provided,  however,  that in
lieu of any such  insurance,  any Borrower or any such Subsidiary may maintain a
system or systems of self-insurance  which are in accord with sound practices of
similarly  situated  corporations  of established  reputation  maintaining  such
systems  and with  respect  to which  such  Borrower  or such  Subsidiary  shall
maintain adequate  insurance  reserves in accordance with GAAP and in accordance
with sound actuarial and insurance principles.

         SECTION 5.04. Conduct of Business and Maintenance of Existence.  Except
as permitted by Section 6.03,  at all times  preserve and keep in full force and
effect,  and cause each  Material  Subsidiary to preserve and keep in full force
and effect,  its  existence,  and rights and franchises  deemed  material to the
Properties,  business, prospects, profits, condition (financial or otherwise) or
operations  of the Company and its  Subsidiaries  taken as a whole,  except that
such rights and franchises and the existence of any Material  Subsidiary  (other
than those of a Subsidiary  Borrower)  may be  terminated  if, in the good faith
judgment of the Board of Directors of the Company,  such  termination  is in the
best interest of the Company and is not disadvantageous to the Lenders.

         SECTION 5.05. Compliance with Laws. Comply, and use its best efforts to
cause each of its  Subsidiaries to comply,  with all applicable  laws, rules and
regulations and orders of any Governmental Authority,  non-compliance with which
could reasonably be expected to have a Material Adverse Effect.

         SECTION 5.06.  Compliance with Environmental  Laws. Comply, and use its
best efforts to cause each of its  Subsidiaries  and each of its Affiliates that
are controlled by it or its  Subsidiaries to comply,  in a timely fashion,  with
the  provisions of all  Environmental  Laws,  failure with which to comply could
reasonably be expected to have a Material  Adverse Effect.  Each Borrower agrees
to defend,  indemnify  and hold the  Administrative  Agent and each Lender,  and
their   respective   directors,    officers,   and   employees   ("Environmental
Indemnitees")  harmless from any loss, liability,  cost, damage, fines, response
costs,  investigative  and monitoring costs,  abatement costs,  attorneys' fees,
experts' or  consultants'  fees,  claims or expenses or any other  Environmental
Liabilities ("Costs") which any such person may incur or suffer as a result of a
breach by the Company or any Subsidiary Borrower of the preceding covenants,  or
as the result of the  breach of any  representation  or  warranty  contained  in
Section 3.07 or as a result of any Environmental Liability,  legal proceeding or
investigation regarding the Company or any of its Subsidiaries,  or any of their
respective plants,  sites or facilities  currently or formerly owned,  operated,
leased or controlled by any of them,  related to Environmental  Laws;  provided,
however,  that with respect to plants,  sites,  or  facilities  formerly  owned,
operated,  leased or controlled by the Company or any of its  Subsidiaries,  the
indemnification  obligations  hereunder  shall relate only to Costs  incurred or
suffered  as a  result  of  an  Environmental  Liability,  legal  proceeding  or
investigation  relating to the ownership,  operation,  lease,  or control by the
Company or any of its  Subsidiaries  of such plants,  sites or  facilities or in
relation  to any plant,  site or facility  jointly  owned,  operated,  leased or
controlled with any other Person, to Costs incurred by virtue of this Agreement.
In no  event  shall  any  Environmental  Indemnitee  be  required  to  make  any
expenditure  or bring any cause of action to enforce the  Company's  obligations
and  liability  under  and  pursuant  to this  Section.  The  Company  and  each
Subsidiary  Borrower  shall  indemnify the respective  Environmental  Indemnitee
regardless  of whether the act,  omission,  facts,  circumstances  or conditions
giving  rise to such  indemnification  were  caused  in  whole or in part by the
respective  Environmental  Indemnitee's  simple (but not gross) negligence.  The
indemnifications  set out in this Section shall survive the  termination of this
Agreement and shall continue to be the personal  liability and obligation of the
Company and each Subsidiary  Borrower,  binding upon them. The  indemnifications
set forth in this Section are also subject to the provisions of Section 10.03(b)
of this  Agreement,  except to the extent  such  provisions  conflict  with this
Section in which case the provisions of this Section shall control.

         SECTION 5.07. Use of Proceeds. Use the proceeds of the Loans made under
this Agreement for working  capital and general  corporate  purposes,  including
non-contested acquisitions,  refinancing of obligations under the ABN Facility A
and the Oryx  Facility,  and  commercial  paper  back-up in the United States of
America and the European Union.  No portion of the Loans will be used,  directly
or  indirectly,  (a) to  purchase  or carry any  Margin  Stock,  (b) to repay or
otherwise  refinance  indebtedness of any Borrower incurred to purchase or carry
any Margin  Stock,  or (c) to extend  credit for the  purpose of  purchasing  or
carrying any Margin Stock.

         SECTION 5.08.  Notice   of   Changed   Credit    Rating.   Notify   the
Administrative    Agent  promptly  on  becoming aware  of any change or proposed
change in any Rating.

         SECTION  5.09.  Subsidiary  Borrowers.  In the  case  of  the  Company,
at all times own,  directly  or indirectly, all outstanding capital stock of the
Subsidiary Borrowers free and clear of all liens or encumbrances.

         SECTION 5.10. Year 2000  Compliance.  Perform,  and, in the case of the
Company,  cause each Material Subsidiary to perform, any reprogramming  required
to permit  the  proper  functioning,  in and  following  the year  2000,  of its
computer systems and equipment containing embedded microchips (including systems
and  equipment  supplied  by others or with  which its  systems  interface)  and
perform the testing of all such systems and equipment,  as so  reprogrammed,  to
the extent necessary to prevent any significant  disruptions to the business and
operations of the Company and its  Subsidiaries on a consolidated  basis,  which
testing shall be completed by September 30, 1999.

                                   ARTICLE VI

                               Negative Covenants

         Until the  Commitments  have expired or terminated and the principal of
and interest on each Loan and all fees payable hereunder have been paid in full:

         SECTION 6.01. Compliance with ERISA. The Company will not, and will not
permit any of its  Subsidiaries  to, (i) engage in any transaction in connection
with which the Company or any of its  Subsidiaries  could be subject to either a
civil penalty  assessed  pursuant to Section  502(i) of ERISA,  a tax imposed by
Section 4975 of the Code, or a lien pursuant to Section 412(n) of the Code, (ii)
terminate  any Plan in a manner,  or take any other  action with  respect to any
such Plan (including,  without limitation, a substantial cessation of operations
within the  meaning of Section  4068(f)  of ERISA),  which  could  result in any
liability of the Company or any of its  Subsidiaries to the PBGC or to a trustee
appointed pursuant to Section 4042(b) or (c) of ERISA, or incur any liability to
the PBGC on account of a  termination  of a Plan  under  Section  4064 of ERISA,
(iii)  fail to make  full  payment  when due of all  amounts  which,  under  the
provisions of any Plan or Section  412(m) of the Code, the Company or any of its
Subsidiaries  is  required  to pay as  contributions  thereto,  (iv)  incur  any
complete or partial withdrawal liability under Title IV of ERISA with respect to
any  Multiemployer  Plan,  or  (v)  permit  to  exist  any  accumulated  funding
deficiency,  whether  or not  waived,  with  respect  to any  Plan,  if,  in the
aggregate,  such penalty or tax or such  liability,  or the failure to make such
payment,  or the  existence  of such  deficiency,  as the case  may be,  exceeds
$25,000,000.

         SECTION 6.02.  Limitation  on Secured  Debt.  Neither the Company nor a
Subsidiary  Borrower  will,  and the Company will not,  permit any  Consolidated
Subsidiary to create, incur, assume or suffer to exist, any Indebtedness secured
by a Lien on any Restricted  Property or any  Indebtedness of the Company or any
Subsidiary,   without  effectively  providing  that  the  Loans  and  any  other
Indebtedness  evidenced by this Agreement  shall be secured  equally and ratably
with  (or  prior  to)  such  secured  Indebtedness,  so  long  as  such  secured
Indebtedness  shall be so secured,  unless,  after giving  effect  thereto,  the
aggregate  principal  amount of all such  secured  Indebtedness  (not  including
secured  Indebtedness  permitted to be secured  under  clauses (a) to (j) below)
plus the  aggregate  "value"  (as  defined  below) of all  "sale  and  leaseback
transaction"  (as  defined  below,  but not  including  any  sale  or  leaseback
transaction  the  proceeds  of which  have  been or will be  applied  to  funded
Indebtedness of the Company or its Subsidiaries within 120 days from the time of
such transaction) would not exceed five percent (5%) of Stockholders'  Equity of
the Company;  provided,  however, that this Section 6.02 shall not apply to, and
there  shall be  excluded  from  secured  Indebtedness  in any  computation  for
purposes of this Section 6.02, any Indebtedness secured by:

                  (a)      Liens existing on the date of this Agreement;

                  (b) any Lien existing on any asset of any  corporation  at the
time such  corporation  becomes a  Consolidated  Subsidiary  and not  created in
contemplation of such event and which does not extend to any other assets of the
Company or any Consolidated Subsidiary;

                  (c) any Lien on any asset  securing  Indebtedness  incurred or
assumed for the purpose of financing  all or any part of the cost of  acquiring,
constructing  or improving such asset,  provided that such Lien attaches to such
asset  concurrently with or within 24 months after the acquisition or completion
of  construction  or  improvement   thereof,   and  provided  further  that  the
Indebtedness  secured  by such Lien  shall  not  exceed  the cost of  acquiring,
constructing or improving such asset;

                  (d) any Lien on any asset of any  corporation  existing at the
time such  corporation is merged or  consolidated  with or into the Company or a
Consolidated Subsidiary and not created in contemplation of such event and which
does  not  extend  to any  other  assets  of  the  Company  or any  Consolidated
Subsidiary;

                  (e) any Lien  existing on any asset  prior to the  acquisition
thereof  by  the  Company  or a  Consolidated  Subsidiary  and  not  created  in
contemplation of such acquisition;

                  (f) any Lien  arising  pursuant  to any  order of  attachment,
distraint or similar legal process arising in connection with court  proceedings
so long as the execution or other enforcement  thereof is effectively stayed and
the claims  secured  thereby are being  contested  in good faith by  appropriate
proceedings;

                  (g) Liens to secure  indebtedness of the pollution  control or
industrial  revenue  bond  type and Liens in favor of the  United  States or any
State  thereof,  or  any  department,  agency,  instrumentality,   or  political
subdivision of any such  jurisdiction,  to secure any indebtedness  incurred for
the  purpose  of  financing  all or any  part of the  purchase  price or cost of
constructing or improving the property subject thereto;

                  (h)  any  Lien  (including  Liens  in  respect  of  production
payments)  to secure the payment of all or any part of the cost of  exploration,
drilling,  mining,  or  development of property which had prior to September 30,
1998,  produced no material volumes of hydrocarbons,  minerals,  timber or other
products or by-products produced or extracted from such property,  provided that
the  Indebtedness  secured by such Lien shall not exceed the cost of  exploring,
drilling,  mining or development  such property;  and provided further that such
Lien shall not extend to any property  other than the property  being  explored,
drilled, mined or developed;

                  (i) Liens securing Indebtedness incurred by the Company or any
of its Subsidiaries to pay all or any part of the cost of exploration,  drilling
or development  any North Sea properties  within the  territorial  waters of the
United Kingdom,  provided, that the Indebtedness secured by such Liens shall not
exceed the cost of such  exploration,  drilling,  or  development;  and provided
further that such Lien shall not extend to any property  other than the property
being explored, drilled or developed; and

                  (j)  any  Lien  arising  out  of the  refinancing,  extension,
renewal or refunding of any Indebtedness secured by any Lien permitted by any of
the  foregoing  clauses  of this  section,  provided  that  the  amount  of such
Indebtedness is not increased and is not secured by any additional assets;

         For  purposes  of this  Section  6.02,  the term  "sale  and  leaseback
transaction"  means any arrangement  with any bank,  insurance  company or other
lender or investor or to which any such lender or investor is a party, providing
for the leasing by the  Company or any of its  Consolidated  Subsidiaries  for a
period,  including renewals, in excess of three years on any Restricted Property
owned or leased by the Company or any of its Consolidated Subsidiaries which has
been  sold  or  transferred,   more  than  120  days  after  the  completion  of
construction and commencement of full operation  thereof,  by the Company or any
of its Consolidated  Subsidiaries to such lender or investor or to any Person to
whom funds have been or are to be  advanced  by such  lender or  investor on the
security of such  Restricted  Property.  For purposes of this Section 6.02,  the
term "value" means, with respect to a sale and leaseback transaction,  as of any
particular  time, an amount equal to the greater of (i) the net proceeds of sale
of  the  Restricted   Property  leased  pursuant  to  such  sale  and  leaseback
transaction,  and (ii) the fair value of such Restricted Property at the time of
entering into such sale and leaseback  transaction as determined by the Board of
Directors of the  Company,  in each case  multiplied  by a fraction of which the
numerator  is the  number  of full  years  remaining  in the  term of the  lease
(without  regard to renewal  options) and the  denominator is the number of full
years of the full term of the lease (without regard to renewal options).

         SECTION 6.03.  Consolidations, Mergers and Sales of Assets.

         (a) Neither the Company nor any Subsidiary  Borrower will be a party to
any  merger  or  consolidation  or sell,  lease  or  otherwise  transfer  all or
substantially  all of its  Property;  provided  that the  Company  may  merge or
consolidate with another  corporation and may sell, lease or otherwise  transfer
all or substantially  all of its Property as an entirety to another  corporation
if (i) the surviving or acquiring corporation (if other than the Company) (A) is
organized under the laws of the United States or a jurisdiction  thereof and (B)
expressly assumes by writing reasonably satisfactory to the Required Lenders the
covenants and obligations in this Agreement,  and (ii) immediately  after giving
effect  to such  transaction,  (x) no  condition  or  event  shall  exist  which
constitutes a Default, (y) the Consolidated Tangible Net Worth shall not be less
than $1,000,000,000, and (z) in the event that any Rating or any expected Rating
(resulting  from  such  merger,  consolidation,  sale,  lease or  transfer)  for
determining the Applicable Rate is determined by reference to Level Three, Four,
Five or Six as provided in the Pricing  Schedule,  the Debt Leverage Ratio shall
be equal to or less than 3.5:1.00;  and provided,  further,  that any Subsidiary
Borrower may merge or consolidate  with another  corporation and may sell, lease
or otherwise transfer all or substantially all of its Property as an entirety to
another corporation if (i) the surviving or acquiring corporation (if other than
another  Subsidiary  Borrower)  (A) is  organized  under the laws of the country
under whose laws such  Subsidiary  Borrower is  organized  and (B)  executes and
delivers to the Administrative  Agent a Joinder Agreement,  (ii) all outstanding
capital stock of the surviving or acquiring  corporation is owned by the Company
free and clear of any Lien,  and (iii)  immediately  after giving effect to such
transaction,  no condition or event shall exist which  constitutes a Default and
the conditions for a Borrowing other than a Refunding  Borrowing as set forth in
Section 4.02  (whether or not a Borrowing  occurs in connection  therewith)  are
satisfied.

         (b) Concurrently with the public disclosure thereof,  the Company shall
give written notice to the  Administrative  Agent and the Lenders  describing in
reasonable detail any proposed  transaction  described in this Section, the date
on which it is proposed to be consummated  and the identity and  jurisdiction of
organization of the proposed successor or transferee corporation.

         (c)  Notwithstanding  anything contained in this Section 6.03, the Oryx
Merger is hereby expressly permitted.

         SECTION 6.04. Transactions with Affiliates. Neither the Company nor any
Subsidiary  Borrower will engage,  directly or  indirectly,  in any  transaction
(including,  without limitation, the purchase, sale or exchange of assets or the
rendering of any service) with any Affiliate,  except in the ordinary  course of
and pursuant to the reasonable  requirements of the Company's or such Subsidiary
Borrower's or such Affiliate's  business and upon fair and reasonable terms that
are  substantially  the same as those which might be obtained in an arm's length
transaction  at the time from  Persons  which are not such an  Affiliate or upon
terms which could not reasonably be expected to have a Material  Adverse Effect;
provided,  however,  that  taxes  may be  allocated  among the  Company  and its
Affiliates  in any  manner  consistent  with  Section  1552  (or  any  successor
provision)  of the Code,  general and  administrative  expenses may be allocated
among the Company and its Affiliates in any manner  consistent  with Section 482
(or any  successor  provision)  of the Code,  and  interest  may be  charged  or
credited to Affiliates in any reasonable manner not inconsistent with the Code.


                                   ARTICLE VII

                                    Guaranty

         SECTION  7.01.  The  Guaranty.  In order to induce the Lenders to enter
into this  Agreement and to extend credit  hereunder and in  recognition  of the
direct  benefits to be received  by the Company  from the  proceeds of the Loans
made to the  Subsidiary  Borrowers,  the  Company  hereby,  unconditionally  and
irrevocably  guarantees as primary obligor and not merely as surety the full and
prompt payment when due, whether upon maturity, by acceleration or otherwise, of
any and all of the Guaranteed  Obligations  of the  Subsidiary  Borrowers to the
Administrative Agent or the Lenders. If any or all of the Guaranteed Obligations
of the Subsidiary  Borrowers to the Administrative  Agent or the Lenders becomes
due  and  payable  hereunder,  the  Company  unconditionally  in the  applicable
currency of such Guaranteed Obligation, promises to pay such indebtedness to the
Administrative Agent for the account of each Lender on demand, together with any
and all reasonable expenses which may be incurred by the Administrative Agent or
the Lenders in collecting any of the Guaranteed Obligations.  This Guaranty is a
guaranty of payment and not collection.  All payments made by Company under this
Guaranty  shall  be made on the same  basis as  payments  by the  Company  under
Sections 2.07 and 2.08.

         SECTION 7.02. Bankruptcy. Additionally, the Company unconditionally and
irrevocably  guarantees the payment of any and all of the Guaranteed Obligations
of the Subsidiary  Borrowers to the Administrative Agent and the Lenders whether
or not then due or payable by such  Subsidiary  Borrowers upon the occurrence in
respect of any  Subsidiary  Borrower of any of the events  specified in Sections
8(h)  or  8(i),  and  unconditionally  and  irrevocably  promises  to  pay  such
Guaranteed  Obligations  to the  Administrative  Agent for the  account  of each
Lender on demand, in the applicable currency of such Guaranteed Obligation.

         SECTION  7.03.  Nature of  Liability.  (a) The liability of the Company
hereunder is exclusive and  independent of any security for or other guaranty of
the Guaranteed  Obligations of the Subsidiary  Borrowers whether executed by the
Company,  any other  guarantor or by any other party,  and the  liability of the
Company  hereunder  shall not be affected or impaired by (i) any direction as to
application of payment by any Subsidiary Borrower or by any other party, or (ii)
any other  continuing or other guaranty,  undertaking or maximum  liability of a
guarantor  or of  any  other  party  as to  the  Guaranteed  Obligations  of the
Subsidiary Borrowers,  or (iii) any payment on or in reduction of any such other
guaranty or  undertaking,  or (iv) any  dissolution,  termination  or  increase,
decrease or change in personnel by the Subsidiary Borrowers,  or (v) any payment
made to the  Administrative  Agent or the Lenders on the Guaranteed  Obligations
which the Administrative  Agent or the Lenders repay to the Subsidiary Borrowers
pursuant  to  court  order  in  any  bankruptcy,  reorganization,   arrangement,
moratorium or other debtor relief  proceeding,  and the Company waives any right
to the deferral or modification  of its  obligations  hereunder by reason of any
such proceeding.

                  (b) If claim is ever made upon the Administrative Agent or any
Lender for repayment or recovery of any amount or amounts received in payment or
on account of any of the Guaranteed  Obligations and any of the aforesaid payees
repays all or part of said amount by reason of (i) any judgment, decree or order
of any court or administrative  body having  jurisdiction over such payee or any
of its property or (ii) any  settlement or compromise of any such claim effected
by such payee with any such claimant (including any Subsidiary  Borrower),  then
and in such event the Company  agrees  that any such  judgment,  decree,  order,
settlement or compromise shall be binding upon the Company,  notwithstanding any
revocation hereof or other instrument evidencing any liability of any Subsidiary
Borrower,  and the Company shall be and remain  liable to the  aforesaid  payees
hereunder  for the amount so repaid or  recovered  to the same extent as if such
amount had never originally been received by any such payee.

         SECTION 7.04.  Independent  Obligation.  The obligations of the Company
hereunder  are  independent  of the  obligations  of any other  guarantor or the
Subsidiary  Borrowers,  and a  separate  action or actions  may be  brought  and
prosecuted  against  the  Company  whether or not action is brought  against any
other  guarantor  or the  Subsidiary  Borrowers  and  whether  or not any  other
guarantor or the  Subsidiary  Borrowers be joined in any such action or actions.
The Company waives,  to the fullest extent  permitted by law, the benefit of any
statute of  limitations  affecting  its liability  hereunder or the  enforcement
thereof.  Any payment by any  Subsidiary  Borrower or other  circumstance  which
operates to toll any statute of limitations as to such Subsidiary Borrower shall
operate to toll the statute of limitations as to the Company. This Guaranty is a
continuing one with respect to the Guaranteed  Obligations,  and all liabilities
to which it applies or may apply under the terms  hereof  shall be  conclusively
presumed to have been created in reliance hereon.

         SECTION 7.05. Authorization.  The Company authorizes the Administrative
Agent and the Lenders  without  notice or demand (except as shall be required by
applicable statute and cannot be waived), and without affecting or impairing its
liability under this Article VII, from time to time to:

                  (a) change the manner,  place or terms of payment  of,  and/or
change or extend the time of payment of, renew,  increase,  accelerate or alter,
any of the  Guaranteed  Obligations  (including  any increase or decrease in the
rate of interest  thereon),  any security  therefor,  or any liability  incurred
directly or indirectly in respect  thereof,  and the Guaranty  herein made shall
apply to the Guaranteed Obligations as so changed, extended, renewed or altered;

                  (b) take and hold  security for the payment of the  Guaranteed
Obligations and sell, exchange,  release,  surrender,  realize upon or otherwise
deal with in any manner and in any order any property by  whomsoever at any time
pledged  or  mortgaged  to  secure,  or  howsoever   securing,   the  Guaranteed
Obligations  or any  liabilities  (including  any of those  hereunder)  incurred
directly  or  indirectly  in  respect  thereof  or  hereof,  and/or  any  offset
thereagainst;

                  (c)  exercise  or refrain from  exercising any rights against
the Subsidiary  Borrowers or others or otherwise act or refrain from acting;

                  (d)  release  or  substitute  any  one   or   more  endorsers,
guarantors,  the Subsidiary  Borrowers or other obligors;

                  (e) settle or compromise  any of the  Guaranteed  Obligations,
any  security  therefor  or any  liability  (including  any of those  hereunder)
incurred  directly  or  indirectly  in  respect  thereof  or  hereof,   and  may
subordinate  the  payment  of all or any  part  thereof  to the  payment  of any
liability  (whether due or not) of the Subsidiary  Borrowers to their  creditors
other than the Lenders;

                  (f) apply any sums by whomsoever paid or howsoever realized to
any  liability  or  liabilities  of the  Subsidiary  Borrowers  to  the  Lenders
regardless of what liability or liabilities of the Subsidiary  Borrowers  remain
unpaid;

                  (g) consent to or waive any breach of, or any act, omission or
default under,  this Agreement or any of the instruments or agreements  referred
to herein,  or otherwise  amend,  modify or supplement  this Agreement or any of
such other instruments or agreements; and/or

                  (h)  take  any  other  action  which  would,  under  otherwise
applicable principles of common law, give rise to a legal or equitable discharge
of the Company from its liabilities under this Guaranty.

         SECTION 7.06. Subordination.  Any of the Indebtedness of the Subsidiary
Borrowers now or hereafter owing to the Guarantor is hereby  subordinated to the
Guaranteed  Obligations of the Subsidiary  Borrowers owing to the Administrative
Agent and the  Lenders;  and if the  Administrative  Agent so requests at a time
when an  Event  of  Default  exists,  all such  Indebtedness  of the  Subsidiary
Borrowers  to the  Company  shall be  collected,  enforced  and  received by the
Company for the  benefit of the  Lenders and be paid over to the  Administrative
Agent on behalf of the Lenders on account of the  Guaranteed  Obligations of the
Subsidiary  Borrowers to the Lenders,  but without affecting or impairing in any
manner the liability of the Company under the other provisions of this Guaranty.

         SECTION 7.07. Waiver. (a) The Company waives any right (except as shall
be  required  by  applicable  statute  and  cannot be  waived)  to  require  the
Administrative  Agent or the  Lenders  to (i)  proceed  against  any  Subsidiary
Borrower,  any other  guarantor  or any other  party,  (ii)  proceed  against or
exhaust any security held from the Subsidiary Borrowers,  any other guarantor or
any other party or (iii) pursue any other remedy in the  Administrative  Agent's
or the Lenders'  power  whatsoever.  The Company  waives any defense based on or
arising out of any defense of the Subsidiary  Borrowers,  any other guarantor or
any other party, other than payment in full of the Guaranteed Obligations, based
on or  arising  out of the  disability  of any  Subsidiary  Borrower,  any other
guarantor  or any  other  party,  or  the  unenforceability  of  the  Guaranteed
Obligations or any part thereof from any cause,  or the cessation from any cause
of the liability of the Subsidiary  Borrowers  other than payment in full of the
Guaranteed  Obligations.  The Administrative Agent and the Lenders may, at their
election,  foreclose on any  security  held by the  Administrative  Agent or the
Lenders  by one or more  judicial  or  nonjudicial  sales,  whether or not every
aspect of any such sale is  commercially  reasonable (to the extent such sale is
permitted  by  applicable  law),  or  exercise  any other  right or  remedy  the
Administrative  Agent and the Lenders may have against the Subsidiary  Borrowers
or any other party, or any security,  without  affecting or impairing in any way
the  liability  of the  Company  hereunder  except to the extent the  Guaranteed
Obligations  have been paid. The Company  waives any defense  arising out of any
such  election by the  Administrative  Agent and the  Lenders,  even though such
election  operates  to  impair  or  extinguish  any  right of  reimbursement  or
subrogation  or other  right or remedy of the  Company  against  any  Subsidiary
Borrower or any other party or any security.

                  (b)  The  Company   waives  all   presentments,   demands  for
performance,  protests  and notices,  including  without  limitation  notices of
nonperformance, notices of protest, notice of acceleration, notices of intent to
accelerate,  notices of dishonor,  notices of acceptance of this  Guaranty,  and
notices of the existence,  creation or incurring of new or additional Guaranteed
Obligations. The Company assumes all responsibility for being and keeping itself
informed of the Subsidiary Borrowers' financial condition and assets, and of all
other  circumstances  bearing  upon the  risk of  nonpayment  of the  Guaranteed
Obligations  and the  nature,  scope and extent of the risks  which the  Company
assumes and incurs hereunder,  and agrees that the Administrative  Agent and the
Lenders  shall have no duty to advise the Company of  information  known to them
regarding such circumstances or risks.

         SECTION 7.08.  Legal  Limitations  of  Liability.  It is the desire and
intent  of the  Company,  the  Administrative  Agent and the  Lenders  that this
Guaranty shall be enforced against the Company to the fullest extent permissible
under  the  laws and  public  policies  applied  in each  jurisdiction  in which
enforcement is sought.  If, however,  and to the extent that, the obligations of
the  Company  under  this  Guaranty  shall  be  adjudicated  to  be  invalid  or
unenforceable  for any reason  (including,  without  limitation,  because of any
applicable   state  or  federal  law  relating  to  fraudulent   conveyances  or
transfers),  then the amount of the Guaranteed  Obligations of the Company shall
be deemed to be reduced  and the  Company  shall pay the  maximum  amount of the
Guaranteed Obligations which would be permissible under applicable law.

         SECTION 7.09.  Discharge Only Upon Payment.  The Company's  obligations
hereunder  shall  remain in full force and  effect  until the  Commitments  have
terminated  and the  principal  and interest on the Loans and all other  amounts
payable by the Borrowers  under this Agreement shall have been paid in full. The
provisions of this Section 7.09 shall survive the  termination of this Agreement
and any  satisfaction or discharge of any Subsidiary  Borrower or the Company by
virtue of any payment, any court order or any applicable law. The obligations of
the Company under this Article VII constitute  the full recourse  obligations of
the Company enforceable against it to the full extent of all its Property.

         SECTION 7.10.  Subrogation.  The Company irrevocably waives any and all
rights to which it may be  entitled,  by  operation  of law or  otherwise,  upon
making any payment hereunder to be subrogated to the rights of the payee against
any  Subsidiary  Borrower  with  respect  to such  payment  or  otherwise  to be
reimbursed,  indemnified  or  exonerated by any  Subsidiary  Borrower in respect
thereof in any  bankruptcy,  insolvency  or  similar  proceeding  involving  any
Subsidiary Borrower as debtor commencing within one year after the making of any
payment by any  Subsidiary  Borrower  under this  Agreement or in respect of the
Loans.  The Company hereby  further waives any right to enforce via  subrogation
any other  remedy  which the  Administrative  Agent or any Lender now has or may
hereafter  have  against any  Subsidiary  Borrower  and any right of  indemnity,
reimbursement  or contribution  against any Subsidiary  Borrower the Company may
have by virtue of the Company's  performance of its obligations  hereunder until
such time as the  Administrative  Agent and the Lenders  have been  indefeasibly
paid in full and the Commitments have expired or been terminated.


                                  ARTICLE VIII

         (f) the  Company  or any of its  Subsidiaries  shall  fail to make  any

         (g)  any  event  or  condition  occurs  that  results  in any  Material
Financial  Obligation  becoming  due  prior to its  scheduled  maturity  or that
enables or permits  (with or without the giving of notice,  the lapse of time or
both) the holder or holders of any Material Financial  Obligation or any trustee
or agent on its or their behalf to cause any Material  Financial  Obligation  to
become due, or to require the prepayment,  repurchase,  redemption or defeasance

sale or transfer of the property or assets securing such Indebtedness;

         (h) Any Borrower or any Material  Subsidiary shall commence a voluntary

compromise,   arrangement,   insolvency,   readjustment  of  debt,  dissolution,
liquidation or other similar law of any  jurisdiction now or hereafter in effect

official of it or any  substantial  part of its property,  and such  involuntary
case or other proceeding  shall remain  undismissed and unstayed for a period of
60 days;  or an order for relief  shall be entered  against any  Borrower or any
Material  Subsidiary  under any Bankruptcy Laws or an order,  judgment or decree

otherwise  be unable to pay when due) or proposes or makes a general  assignment
or an arrangement  or composition  with or for the benefit of its creditors or a
moratorium is agreed or declared in respect of or affecting all or substantially
all of the Indebtedness of such Subsidiary Borrower;

         (k) The Company or any ERISA  Affiliate shall fail to pay when due (and
not being contested in good faith) an amount or amounts aggregating in excess of
the ERISA  Obligation  Threshold which it shall have become liable to pay to the
PBGC,  the  Internal  Revenue  Service  or  the  Department  of  Labor  or  to a
Multiemployer  Plan under Title IV of ERISA;  or notice of intent to terminate a
Plan or Plans  having  aggregate  Unfunded  Benefit  Liabilities  in  excess  of

combination  of the foregoing;  or the PBGC shall  institute  proceedings  under
Title IV of ERISA to  terminate,  to impose  liability  (other than for premiums
under Section 4007 of ERISA) in respect of or to cause a trustee to be appointed

withdrawal  from,  or a default,  within the  meaning of Section  4219(c)(5)  of
ERISA,  with respect to, one or more  Multiemployer  Plans which would cause the
Company or any ERISA Affiliate to incur a current  payment  obligation in excess

contested  the payment  thereof)  shall be  rendered  against the Company or any
Material  Subsidiary and such judgment or order shall continue  unsatisfied  and
not stayed,  bonded,  vacated or  suspended by  agreement  with the  beneficiary

event  (other  than  an  event  with  respect  to  any  Borrower  described   in
clause  (h)   or   (i)   of   this    Article),   and   at  any time  thereafter
during the continuance of such event, (i) the  Administrative  Agent may, and at
the request of the Required Lenders shall, by notice to the Company, take either
or both of the following  actions,  at the same or different times (A) terminate
the  Commitments  and thereupon the  Commitments  shall  terminate  immediately,
and/or (B) declare the Loans then  outstanding  (together with accrued  interest
thereon and all fees and all other  amounts  payable  hereunder) to be, and such
amounts shall thereupon become, immediately due and payable without presentment,
demand, protest,  notice to accelerate,  notice of intent to accelerate or other
notice of any kind,  all of which are hereby waived by each  Borrower;  provided
that in the case of any of the Events of Default  specified in clause (h) or (i)
above with  respect to any  Borrower,  without any notice to any Borrower or any
other act by the Administrative  Agent or the Lenders, (i) the Commitments shall
thereupon  terminate and the Loans (together with accrued  interest  thereon and
all fees and all other amounts payable  hereunder) shall become  immediately due
and payable without  presentment,  demand,  protest or other notice of any kind,
all of which are hereby waived by each  Borrower;  (ii) each Lender may exercise
its rights of offset against each account and all other property of any Borrower
or both in the  possession of such Lender,  which right is hereby granted by the
Borrowers to the Lenders; and (iii) the Administrative Agent and each Lender may
exercise  any and all other  rights  pursuant to this  Agreement,  at law and in
equity.


                                   ARTICLE IX

                            The Administrative Agent

         Each of the Lenders  hereby  irrevocably  appoints  the  Administrative
Agent as its agent and authorizes the Administrative  Agent to take such actions
on its behalf and to exercise such powers as are delegated to the Administrative
Agent by the  terms  hereof,  together  with  such  actions  and  powers  as are
reasonably incidental thereto.

         The bank serving as the  Administrative  Agent hereunder shall have the
same rights and powers in its  capacity as a Lender as any other  Lender and may
exercise the same as though it were not the Administrative  Agent, and such bank
and its Affiliates may accept deposits from, lend money to and generally  engage
in any kind of business with each Borrower or any Subsidiary or other  Affiliate
thereof as if it were not the Administrative Agent hereunder.

         The  Administrative  Agent  shall not have any  duties  or  obligations
except those expressly set forth herein.  Without limiting the generality of the
foregoing, (a) the Administrative Agent shall not be subject to any fiduciary or
other  implied  duties,  regardless  of whether a Default  has  occurred  and is
continuing,  (b) the  Administrative  Agent  shall not have any duty to take any
discretionary action or exercise any discretionary  powers, except discretionary
rights and powers expressly contemplated hereby that the Administrative Agent is
required to exercise in writing by the Required Lenders (or such other number or
percentage  of the  Lenders as shall be  necessary  under the  circumstances  as
provided in Section  10.02),  and (c) except as expressly set forth herein,  the
Administrative  Agent  shall  not have any duty to  disclose,  and  shall not be
liable for the failure to disclose,  any information relating to any Borrower or
any of its Subsidiaries  that is communicated to or obtained by the bank serving
as  Administrative  Agent  or  any  of  its  Affiliates  in  any  capacity.  The
Administrative Agent shall not be liable for any action taken or not taken by it
with the consent or at the request of the Required Lenders (or such other number
or percentage of the Lenders as shall be necessary  under the  circumstances  as
provided  in Section  10.02) or in the  absence of its own gross  negligence  or
wilful  misconduct.  The  Administrative  Agent  shall  be  deemed  not to  have
knowledge of any Default unless and until written notice thereof is given to the
Administrative  Agent by any Borrower or a Lender, and the Administrative  Agent
shall not be  responsible  for or have any duty to ascertain or inquire into (i)
any statement,  warranty or  representation  made in or in connection  with this
Agreement,  (ii) the  contents  of any  certificate,  report  or other  document
delivered  hereunder  or  in  connection  herewith,  (iii)  the  performance  or
observance of any of the covenants,  agreements or other terms or conditions set
forth herein, (iv) the validity, enforceability, effectiveness or genuineness of
this  Agreement  or any other  agreement,  instrument  or  document,  or (v) the
satisfaction of any condition set forth in Article IV or elsewhere herein, other
than to confirm  receipt of items  expressly  required  to be  delivered  to the
Administrative Agent.

         The Administrative  Agent shall be entitled to rely upon, and shall not
incur any liability for relying upon, any notice, request, certificate, consent,
statement,  instrument,  document or other writing  believed by it to be genuine
and to have been signed or sent by the proper Person. The  Administrative  Agent
also may rely upon any statement  made to it orally or by telephone and believed
by it to be made by the proper  Person,  and shall not incur any  liability  for
relying thereon.  The  Administrative  Agent may consult with legal counsel (who
may be counsel for the  Borrowers),  independent  accountants  and other experts
selected by it, and shall not be liable for any action  taken or not taken by it
in accordance with the advice of any such counsel, accountants or experts.

         The  Administrative  Agent  may  perform  any and all  its  duties  and
exercise  its  rights  and  powers  by or  through  any one or  more  sub-agents
appointed by the  Administrative  Agent. The  Administrative  Agent and any such
sub-agent  may perform any and all its duties and exercise its rights and powers
through their  respective  Related  Parties.  The exculpatory  provisions of the
preceding  paragraphs  shall  apply to any  such  sub-agent  and to the  Related
Parties of the Administrative  Agent and any such sub-agent,  and shall apply to
their  respective  activities in connection  with the  syndication of the credit
facilities provided for herein as well as activities as Administrative Agent.

         Subject to the appointment and acceptance of a successor Administrative
Agent as provided in this paragraph,  the Administrative Agent may resign at any
time by notifying the Lenders and each Borrower.  Upon any such resignation,  so
long as no Default exists, the Company shall have the right, with the consent of
the Required Lenders, such consent not to be unreasonably withheld, to appoint a
successor.  If a Default  exists,  the Required  Lenders shall have the right to
appoint a successor without the consent of the Company or any other Borrower. If
no  successor  shall  have been so  appointed  by the  Company  or the  Required
Lenders, as applicable,  and shall have accepted such appointment within 30 days
after the retiring  Administrative  Agent gives notice of its resignation,  then
the  retiring  Administrative  Agent may,  on behalf of the  Lenders,  appoint a
successor  Administrative Agent which shall be a bank with an office in New York
City,  New York,  or an  Affiliate  of any such  bank,  and which has a combined
capital  and  surplus  of at  least  $500,000,000.  Upon the  acceptance  of its
appointment as  Administrative  Agent  hereunder by a successor,  such successor
shall succeed to and become vested with all the rights,  powers,  privileges and
duties of the retiring  Administrative  Agent,  and the retiring  Administrative
Agent shall be discharged  from its duties and obligations  hereunder.  The fees
payable by the Company to a successor  Administrative Agent shall be the same as
those payable to its predecessor unless otherwise agreed between the Company and
such successor.  After the Administrative  Agent's  resignation  hereunder,  the
provisions  of this Article and Section  10.03 shall  continue in effect for the
benefit  of  such  retiring  Administrative  Agent,  its  sub-agents  and  their
respective  Related  Parties in respect  of any  actions  taken or omitted to be
taken by any of them while it was acting as Administrative Agent.

         Each  Lender  acknowledges  that  it  has,  independently  and  without
reliance  upon the  Administrative  Agent or any other  Lender and based on such
documents  and  information  as it has deemed  appropriate,  made its own credit
analysis  and  decision  to  enter  into  this   Agreement.   Each  Lender  also
acknowledges  that  it  will,   independently  and  without  reliance  upon  the
Administrative  Agent  or any  other  Lender  and  based on such  documents  and
information as it shall from time to time deem appropriate, continue to make its
own decisions in taking or not taking action under or based upon this Agreement,
any related agreement or any document furnished hereunder or thereunder.

                                    ARTICLE X

                                  Miscellaneous

         SECTION  10.01.  Notices.  Except  in the  case of  notices  and  other
communications  expressly  permitted to be given by  telephone,  all notices and
other  communications  provided  for  herein  shall be in  writing  and shall be
delivered  by  hand  or  overnight  courier  service,  mailed  by  certified  or
registered mail or sent by telecopy, as follows:

                  (a) if to Kerr-McGee  Corporation, to it at 123 Robert S. Kerr
Avenue,  Oklahoma City, Oklahoma, 73102, Attention of Melody Walke (Telecopy No.
(405) 270-3852);

                  (b) if to any  Subsidiary  Borrower,  to its  attention at the
address and the telephone and telecopy numbers set forth in clause (a) above;

                  (c)  if to the  Administrative  Agent,  to it at  its  offices
located at One Liberty  Plaza,  New York,  New York,  10006-1404,  Attention  of
Manager, Agency Services (Telecopy No. (212) 428-2310);

                  (d) if to any other Lender,  to it at its address (or telecopy
number) set forth in the Notice Schedule.

Any party hereto may change its address or telecopy number for notices and other
communications  hereunder by notice to the other parties hereto. All notices and
other communications given to any party hereto in accordance with the provisions
of this Agreement shall be deemed to have been given on the date of receipt.

         SECTION  10.02.  Waivers;  Amendments.  (a) No  failure or delay by the
Administrative  Agent or any Lender in exercising  any right or power  hereunder
shall operate as a waiver thereof,  nor shall any single or partial  exercise of
any such  right or  power,  or any  abandonment  or  discontinuance  of steps to
enforce such a right or power, preclude any other or further exercise thereof or
the  exercise  of any other  right or power.  The  rights  and  remedies  of the
Administrative  Agent  and the  Lenders  hereunder  are  cumulative  and are not
exclusive of any rights or remedies that they would otherwise have. No waiver of
any  provision  of this  Agreement  or consent to any  departure by any Borrower
therefrom shall in any event be effective  unless the same shall be permitted by
paragraph  (b) of this  Section,  and  then  such  waiver  or  consent  shall be
effective  only in the  specific  instance  and for the purpose for which given.
Without limiting the generality of the foregoing, the making of a Loan shall not
be  construed  as  a  waiver  of  any   Default,   regardless   of  whether  the
Administrative  Agent or any  Lender may have had  notice or  knowledge  of such
Default at the time.

                  (b) Neither this  Agreement  nor any  provision  hereof may be
waived,  amended or modified  except  pursuant to an agreement or  agreements in
writing entered into by each Borrower and the Required Lenders, or each Borrower
and the Administrative Agent with the consent of the Required Lenders;  provided
that no such  agreement  shall (i) increase the Commitment of any Lender without
the written consent of such Lender,  (ii) increase the maximum amount  available
under the Foreign  Available  Amount without the written  consent of each Lender
affected thereby, such consent not to be unreasonably withheld, (iii) reduce the
principal amount of any Loan or reduce the rate of interest  thereon,  or reduce
any fees payable hereunder,  without the written consent of each Lender affected
thereby,  (iv) postpone the scheduled date of payment of the principal amount of
any Loan, or any interest thereon, or any fees payable hereunder,  or reduce the
amount of, waive or excuse any such payment,  or postpone the scheduled  date of
expiration  of any  Commitment,  without  the  written  consent  of each  Lender
affected thereby, (v) change Section 2.15(b) or (c) in a manner that would alter
the pro rata sharing of payments required  thereby,  without the written consent
of each  Lender,  (vi)  change  any of the  provisions  of this  Section  or the
definition of "Required  Lenders" or any other provision  hereof  specifying the
number or  percentage of Lenders  required to waive,  amend or modify any rights
hereunder or make any determination or grant any consent hereunder,  without the
written  consent of each Lender,  (vii) change any of the  provisions of Section
10.04(a)  without the written consent of each Lender,  (viii) change the Type of
Loans  available  or the  currencies  in which Loans are  available  without the
written  consent  of each  Lender,  (ix)  permit a change  in  ownership  of any
Subsidiary  Borrower  unless  the  Company  maintains  100%  direct or  indirect
ownership without the written consent of each Lender, or (x) release the Company
from its  obligations  contained  in Article VII without the written  consent of
each Lender;  provided  further that no such  agreement  shall amend,  modify or
otherwise  affect the  rights or duties of the  Administrative  Agent  hereunder
without the prior written consent of the Administrative Agent .

         SECTION 10.03.  Expenses;  Indemnity;  Damage Waiver. (a) The Borrowers
shall  pay  (i)  all   reasonable   out-of-pocket   expenses   incurred  by  the
Administrative Agent and its Affiliates,  including the reasonable fees, charges
and  disbursements  of Vinson & Elkins  L.L.P.,  counsel  to the  Administrative
Agent, in connection with the syndication of the credit facilities  provided for
herein,  reasonable publicity expenses agreed to by the Company, the preparation
and administration of this Agreement or any amendments, modifications or waivers
of the provisions hereof (whether or not the transactions contemplated hereby or
thereby shall be consummated),  and (ii) all out-of-pocket  expenses incurred by
the  Administrative  Agent  or any  Lender,  including  the  fees,  charges  and
disbursements  of any counsel  for the  Administrative  Agent or any Lender,  in
connection  with the  enforcement or protection of its rights in connection with
this Agreement,  including its rights under this Section,  or in connection with
the Loans made hereunder,  including all such  out-of-pocket  expenses  incurred
during any workout, restructuring or negotiations in respect of such Loans.

                  (b) The Borrowers shall indemnify the Administrative Agent and
each Lender,  and each Related Party of any of the foregoing  Persons (each such
Person being called an "Indemnitee")  against, and hold each Indemnitee harmless
from, any and all losses,  claims,  damages,  liabilities and related  expenses,
including the reasonable fees,  charges and disbursements of any counsel for any
Indemnitee,  incurred by or asserted  against any Indemnitee  arising out of, in
connection  with,  or as a  result  of (i) the  execution  or  delivery  of this
Agreement or any agreement or instrument contemplated hereby, the performance by
the parties hereto of their respective obligations hereunder or the consummation
of the Transactions or any other transactions contemplated hereby, (ii) any Loan
or the use of the proceeds  therefrom,  (iii) any actual or alleged  presence or
release of Hazardous  Materials on or from any property owned or operated by any
Borrower or any of its Subsidiaries,  or any Environmental  Liability related in
any way to any  Borrower  or any of its  Subsidiaries,  or (iv)  any  actual  or
prospective claim,  litigation,  investigation or proceeding  relating to any of
the  foregoing,  whether  based  on  contract,  tort  or any  other  theory  and
regardless  of whether any  Indemnitee  is a party  thereto;  provided that such
indemnity shall not, as to any Indemnitee,  be available to the extent that such
losses, claims, damages, liabilities or related expenses resulted from the gross
negligence or wilful misconduct of such Indemnitee.

                  (c) To the extent  that any  Borrower  fails to pay any amount
required to be paid by it to the Administrative Agent under paragraph (a) or (b)
of this Section, each Lender severally agrees to pay to the Administrative Agent
such  Lender's  Applicable  Percentage  (determined  as of  the  time  that  the
applicable  unreimbursed  expense or indemnity payment is sought) of such unpaid
amount;  provided that the  unreimbursed  expense or  indemnified  loss,  claim,
damage,  liability  or related  expense,  as the case may be, was incurred by or
asserted against the Administrative Agent in its capacity as such.

                  (d) To the extent  permitted by applicable  law, each Borrower
shall not assert,  and hereby waive,  any claim against any  Indemnitee,  on any
theory of liability,  for special,  indirect,  consequential or punitive damages
(as opposed to direct or actual damages)  arising out of, in connection with, or
as a result of, this  Agreement  or any  agreement  or  instrument  contemplated
hereby, the Transactions, any Loan or the use of the proceeds thereof.

                  (e) All  amounts  due  under  this  Section  shall be  payable
promptly after written demand therefor.

         SECTION  10.04.  Successors  and Assigns.  (a) The  provisions  of this
Agreement  shall be binding upon and inure to the benefit of the parties  hereto
and their  respective  successors and assigns  permitted  hereby,  except that a
Borrower may not assign or otherwise  transfer any of its rights or  obligations
hereunder  without the prior  written  consent of each Lender (and any attempted
assignment  or transfer by a Borrower  without  such  consent  shall be null and
void).  Nothing in this Agreement,  expressed or implied,  shall be construed to
confer  upon  any  Person  (other  than the  parties  hereto,  their  respective
successors  and  assigns   permitted   hereby  and,  to  the  extent   expressly
contemplated hereby, the Related Parties of each of the Administrative Agent and
the Lenders) any legal or equitable right, remedy or claim under or by reason of
this Agreement.

                  (b) Any Lender may  assign to one or more  assignees  all or a
portion of its rights and obligations  under this Agreement  (including all or a
portion of its Commitment and the Loans at the time owing to it); provided, that
(i) except in the case of an assignment  to a Lender,  an Affiliate of a Lender,
or  to  the  United  States  Federal  Reserve  Banks,   each  Borrower  and  the
Administrative  Agent must give their prior written  consent to such  assignment
(which consent shall not be unreasonably  withheld),  (ii) except in the case of
an  assignment  of  the  entire  remaining  amount  of  the  assigning  Lender's
Commitment, the amount of the Commitment of the assigning Lender subject to each
such  assignment  (determined as of the date the Assignment and Acceptance  with
respect to such assignment is delivered to the  Administrative  Agent) shall not
be less than  $5,000,000,  (iii)  each  partial  assignment  shall be made as an
assignment  of a  proportionate  part of all the assigning  Lender's  rights and
obligations  under this  Agreement,  (iv) the parties to each  assignment  shall
execute and deliver to the  Administrative  Agent an Assignment and  Acceptance,
together with a processing and recordation fee of $3,500,  and (v) the assignee,
if it shall  not be a  Lender,  shall  deliver  to the  Administrative  Agent an
administrative  questionnaire in the form supplied by the Administrative  Agent;
and provided further that any consent of the Borrowers  otherwise required under
this paragraph  shall not be required if an Event of Default has occurred and is
continuing.  Subject to acceptance and recording  thereof  pursuant to paragraph
(d) of this  Section,  from and  after  the  effective  date  specified  in each
Assignment and Acceptance,  the assignee thereunder shall be a party hereto and,
to the extent of the interest  assigned by such Assignment and Acceptance,  have
the rights and obligations of a Lender under this  Agreement,  and the assigning
Lender  thereunder  shall,  to the  extent  of the  interest  assigned  by  such
Assignment and Acceptance, be released from its obligations under this Agreement
(and, in the case of an Assignment and Acceptance  covering all of the assigning
Lender's rights and obligations under this Agreement, such Lender shall cease to
be a party hereto but shall  continue to be entitled to the benefits of Sections
2.12, 2.13, 2.14 and 10.03). Any assignment or transfer by a Lender of rights or
obligations  under this Agreement that does not comply with this paragraph shall
be  treated  for  purposes  of this  Agreement  as a sale by  such  Lender  of a
participation in such rights and obligations in accordance with paragraph (e) of
this Section.

                  (c) The  Administrative  Agent,  acting for this purpose as an
agent of all  Borrowers,  shall maintain at one of its offices in New York City,
New  York,  a copy of  each  Assignment  and  Acceptance  delivered  to it and a
register for the recordation of the names and addresses of the Lenders,  and the
Commitment of, and principal  amount of the Loans owing to, each Lender pursuant
to the terms  hereof  from time to time (the  "Register").  The  entries  in the
Register shall be conclusive,  and each Borrower,  the Administrative  Agent and
the  Lenders  may treat each  Person  whose  name is  recorded  in the  Register
pursuant  to the terms  hereof as a Lender  hereunder  for all  purposes of this
Agreement,  notwithstanding  notice  to the  contrary.  The  Register  shall  be
available for inspection by any Borrower and any Lender,  at any reasonable time
and from time to time upon reasonable prior notice.

                  (d)  Upon  its  receipt  of a duly  completed  Assignment  and
Acceptance  executed by an  assigning  Lender and an  assignee,  the  assignee's
completed   administrative   questionnaire   in  the   form   supplied   by  the
Administrative  Agent (unless the assignee shall already be a Lender hereunder),
the processing and  recordation fee referred to in paragraph (b) of this Section
and any written  consent to such  assignment  required by paragraph  (b) of this
Section,  the  Administrative  Agent shall accept such Assignment and Acceptance
and record the  information  contained  therein in the  Register.  No assignment
shall be effective for purposes of this Agreement unless it has been recorded in
the Register as provided in this paragraph.

                  (e) Any Lender may, without the consent of any Borrower or the
Administrative Agent, sell participations to one or more banks or other entities
(a  "Participant")  in all or a portion of such Lender's  rights and obligations
under this Agreement (including all or a portion of its Commitment and the Loans
owing to it);  provided that (i) such Lender's  obligations under this Agreement
shall remain unchanged,  (ii) such Lender shall remain solely responsible to the
other parties  hereto for the  performance  of such  obligations  and (iii) each
Borrower,  the Administrative Agent and the other Lenders shall continue to deal
solely and directly with such Lender in connection with such Lender's rights and
obligations under this Agreement.  Any agreement or instrument pursuant to which
a Lender sells such a participation  shall provide that such Lender shall retain
the  sole  right  to  enforce  this  Agreement  and to  approve  any  amendment,
modification  or waiver of any provision of this  Agreement;  provided that such
agreement  or  instrument  may provide  that such  Lender will not,  without the
consent  of the  Participant,  agree to any  amendment,  modification  or waiver
described  in  the  first   proviso  to  Section   10.02(b)  that  affects  such
Participant. Subject to paragraph (f) of this Section, each Borrower agrees that
each  Participant  shall be entitled to the benefits of Sections 2.12,  2.13 and
2.14 to the same extent as if it were a Lender and had  acquired its interest by
assignment pursuant to paragraph (b) of this Section. To the extent permitted by
law, each Participant also shall be entitled to the benefits of Section 10.08 as
though it were a Lender;  provided  such  Participant  agrees to be  subject  to
Section 2.15(c) and 2.16 as though it were a Lender.

                  (f) A Participant shall not be entitled to receive any greater
payment  under Section 2.12 or 2.14 than the  applicable  Lender would have been
entitled to receive with respect to the participation  sold to such Participant,
unless  the  sale of the  participation  to such  Participant  is made  with the
Company's prior written consent. A Participant that would be a Foreign Lender if
it were a Lender  shall not be entitled to the  benefits of Section  2.14 unless
each Borrower is notified of the participation sold to such Participant and such
Participant  agrees,  for the benefit of each  Borrower,  to comply with Section
2.14(e) as though it were a Lender.

                  (g) Any  Lender  may at any time  pledge or assign a  security
interest  in all or any  portion of its rights  under this  Agreement  to secure
obligations  of such  Lender,  including  any  pledge  or  assignment  to secure
obligations to a United States Federal  Reserve Bank, and this Section shall not
apply to any such pledge or assignment of a security interest;  provided that no
such pledge or assignment of a security interest shall release a Lender from any
of its obligations hereunder or substitute any such pledgee or assignee for such
Lender as a party hereto.

                  (h) Any assignee or Participant under this Section 10.04 shall
have an office or a branch or an  Affiliate  available  to it and located in the
appropriate jurisdiction through which such assignee or Participant can make any
Eurodollar Loan or a Loan denominated in an Alternate Currency as required under
this Agreement.

                  (i) Notwithstanding anything to the contrary contained herein,
any Lender (a "Granting  Lender") may grant to a special purpose funding vehicle
(an "SPC") sponsored by such Granting Lender, identified as such in writing from
time to time by the Granting Lender to the Administrative Agent and the Company,
the  option  to  provide  to the  Company  all or any part of any Loan that such
Granting Lender would otherwise be obligated to make to the Borrower pursuant to
this Agreement,  provided that (i) nothing herein shall  constitute a commitment
by any SPC to make  any  Loan and (ii) if an SPC  elects  not to  exercise  such
option or otherwise  fails to provide all or any part of such Loan, the Granting
Lender shall be obligated to make such Loan  pursuant to the terms  hereof.  The
making  of a Loan  by an SPC  hereunder  shall  utilize  the  Commitment  of the
Granting  Lender  to the same  extent,  and as if,  such  Loan  were made by the
Granting Lender. Each party hereto hereby agrees that no SPC shall be liable for
any payment under this  Agreement  for which a Lender would  otherwise be liable
(all  liability for which,  if any, shall remain with the Granting  Lender).  In
furtherance of the foregoing,  each party hereto hereby agrees (which  agreement
shall survive the termination of this Agreement) that, prior to the date that is
one  year  and  one day  after  the  later  of (A)  the  payment  in full of all
outstanding commercial paper or other senior indebtedness of any SPC and (B) the
Final Maturity Date, it will not institute against,  or join any other person in
instituting  against,  such  SPC any  bankruptcy,  reorganization,  arrangement,
insolvency or liquidation  proceedings or similar  proceedings under the laws of
the United States or any state thereof. In addition, notwithstanding anything to
the contrary  contained in this Section 10.04,  any SPC may, with notice to, but
without prior written  consent of, the Company,  any Subsidiary  Borrower or the
Administrative Agent and without paying any processing fee therefor,  assign all
or a portion  of its  interests  in any Loans to the  Granting  Lender or to any
financial  institutions  providing liquidity and/or credit support to or for the
account  of such  SPC to fund  the  Loans  made by such  SPC or to  support  the
securities  (if any)  issued by such SPC to fund such  Loans and  disclose  on a
confidential  basis  any  non-public  information  relating  to its Loans to any
rating agency,  commercial paper dealer or provider of any surety,  guarantee or
liquidity or credit enhancement to such SPC.

         SECTION 10.05. Survival. All covenants, agreements, representations and
warranties  made  by  any  Borrower  herein  and in the  certificates  or  other
instruments  delivered in connection with or pursuant to this Agreement shall be
considered  to have been  relied  upon by the  other  parties  hereto  and shall
survive  the  execution  and  delivery of this  Agreement  and the making of any
Loans,  regardless of any  investigation  made by any such other party or on its
behalf and notwithstanding  that the Administrative Agent or any Lender may have
had notice or knowledge of any Default or incorrect  representation  or warranty
at the time any credit is extended  hereunder,  and shall continue in full force
and effect as long as the  principal  of or any accrued  interest on any Loan or
any fee or any other amount  payable  under this  Agreement is  outstanding  and
unpaid  and so long as the  Commitments  have not  expired  or  terminated.  The
provisions of Sections  2.12,  2.13,  2.14 and 10.03 shall survive and remain in
full  force  and  effect  regardless  of the  consummation  of the  transactions
contemplated  hereby,  the repayment of the Loans, the expiration or termination
of the Commitments or the termination of this Agreement or any provision hereof.

         SECTION 10.06. Counterparts; Integration; Effectiveness. This Agreement
may be executed in  counterparts  (and by different  parties hereto on different
counterparts), each of which shall constitute an original, but all of which when
taken  together  shall  constitute a single  contract.  This  Agreement  and any
separate letter  agreements  with respect to fees payable to the  Administrative
Agent  constitute the entire contract among the parties  relating to the subject
matter hereof and supersede any and all previous  agreements and understandings,
oral or written,  relating to the subject matter  hereof.  Except as provided in
Section 4.01,  this  Agreement  shall become  effective  when it shall have been
executed by the  Administrative  Agent and when the  Administrative  Agent shall
have  received  counterparts  hereof  which,  when  taken  together,   bear  the
signatures of each of the other parties hereto,  and thereafter shall be binding
upon and  inure to the  benefit  of the  parties  hereto  and  their  respective
successors and assigns.  Delivery of an executed counterpart of a signature page
of this  Agreement  by  telecopy  shall be  effective  as delivery of a manually
executed counterpart of this Agreement.

         SECTION 10.07. Severability. Any provision of this Agreement held to be
invalid,  illegal  or  unenforceable  in  any  jurisdiction  shall,  as to  such
jurisdiction,  be  ineffective to the extent of such  invalidity,  illegality or
unenforceability without affecting the validity,  legality and enforceability of
the remaining provisions hereof; and the invalidity of a particular provision in
a  particular  jurisdiction  shall not  invalidate  such  provision in any other
jurisdiction.

         SECTION  10.08.  Right of  Setoff.  If an Event of  Default  shall have
occurred and be  continuing,  each Lender and each of its  Affiliates  is hereby
authorized at any time and from time to time, to the fullest extent permitted by
law, to set off and apply any and all  deposits  (general  or  special,  time or
demand, provisional or final) at any time held and other obligations at any time
owing by such  Lender or  Affiliate  to or for the credit or the  account of any
Borrower  against  any of and  all  the  obligations  of  such  Borrower  now or
hereafter  existing under this Agreement  held by such Lender,  irrespective  of
whether or not such Lender shall have made any demand under this  Agreement  and
although such obligations may be unmatured. The rights of each Lender under this
Section are in addition to other rights and remedies  (including other rights of
setoff) which such Lender may have.

         SECTION  10.09.  Governing Law;  Jurisdiction;  Consent  to  Service of
Process.  (a)  This   Agreement  shall  be  construed  in  accordance  with  and
governed by the law of the State of New York.

                  (b)  Each  Borrower  hereby  irrevocably  and  unconditionally
submits,  for itself and its property,  to the nonexclusive  jurisdiction of the
Supreme  Court of the State of New York  sitting  in New York  County and of the
United  States  District  Court of the  Southern  District of New York,  and any
appellate court from any thereof,  in any action or proceeding arising out of or
relating to this  Agreement,  or for recognition or enforcement of any judgment,
and each of the parties hereto hereby  irrevocably  and  unconditionally  agrees
that all  claims in respect of any such  action or  proceeding  may be heard and
determined  in such New York State or, to the extent  permitted  by law, in such
Federal  court.  Each of the parties  hereto agrees that a final judgment in any
such  action or  proceeding  shall be  conclusive  and may be  enforced in other
jurisdictions  by suit on the judgment or in any other  manner  provided by law.
Nothing in this Agreement shall affect any right that the  Administrative  Agent
or any Lender may otherwise  have to bring any action or proceeding  relating to
this  Agreement  against  any  Borrower or its  properties  in the courts of any
jurisdiction.

                  (c)  Each  Borrower  hereby  irrevocably  and  unconditionally
waives,  to the  fullest  extent  it may  legally  and  effectively  do so,  any
objection which it may now or hereafter have to the laying of venue of any suit,
action or proceeding  arising out of or relating to this  Agreement in any court
referred to in paragraph (b) of this Section.  Each of the parties hereto hereby
irrevocably  waives,  to the fullest extent  permitted by law, the defense of an
inconvenient  forum to the  maintenance of such action or proceeding in any such
court.

                  (d)  Each  party to this  Agreement  irrevocably  consents  to
service  of  process  to the  General  Counsel  of  the  Company  at  Kerr-McGee
Corporation, 123 Robert S. Kerr Avenue, Oklahoma City, Oklahoma, 73102 (Telecopy
No.  (405)  270-4211).  Nothing in this  Agreement  will affect the right of any
party to this Agreement to serve process in any other manner permitted by law.

         SECTION 10.10.  WAIVER OF JURY TRIAL.  Each party hereto hereby waives,
to the fullest  extent  permitted by applicable  law, any right it may have to a
trial by jury in any legal proceeding  directly or indirectly  arising out of or
relating to this  Agreement or the  Transactions  contemplated  hereby  (whether
based on contract,  tort or any other  theory).  Each party hereto (a) certifies
that no  representative,  agent or attorney of any other party has  represented,
expressly  or  otherwise,  that such  other  party  would  not,  in the event of
litigation,  seek to enforce the foregoing waiver and (b)  acknowledges  that it
and the other parties  hereto have been induced to enter into this Agreement by,
among other things, the mutual waivers and certifications in this Section.

         SECTION 10.11. Headings.  Article and Section headings and the Table of
Contents used herein are for convenience of reference only, are not part of this
Agreement  and  shall  not  affect  the   construction  of,  or  be  taken  into
consideration in interpreting, this Agreement.

         SECTION 10.12.  Confidentiality.  Each of the Administrative  Agent and
the Lenders  agrees to  maintain  the  confidentiality  of the  Information  (as
defined  below),  except that  Information  may be disclosed  (a) to its and its
Affiliates' directors,  officers,  employees and agents,  including accountants,
legal counsel and other advisors (it being  understood  that the Persons to whom
such  disclosure  is made will be  informed of the  confidential  nature of such
Information and instructed to keep such  Information  confidential),  (b) to the
extent  requested by any  regulatory  authority,  (c) to the extent  required by
applicable laws or regulations or by any subpoena or similar legal process,  (d)
to any other party to this Agreement, (e) in connection with the exercise of any
remedies hereunder or any suit, action or proceeding  relating to this Agreement
or the enforcement of rights hereunder,  (f) subject to an agreement  containing
provisions  substantially the same as those of this Section,  to any assignee of
or Participant in, or any prospective  assignee of or Participant in, any of its
rights or obligations under this Agreement,  (g) with the consent of the Company
or (h) to the extent such Information (i) becomes publicly  available other than
as a  result  of a breach  of this  Section  or (ii)  becomes  available  to the
Administrative  Agent or any  Lender on a  nonconfidential  basis  from a source
other than a Borrower. For the purposes of this Section, "Information" means all
information  received  from  any  Borrower  relating  to  such  Borrower  or its
business,   other  than  any  such   information   that  is   available  to  the
Administrative  Agent  or  any  Lender  on  a  nonconfidential  basis  prior  to
disclosure by such Borrower;  provided that, in the case of information received
from such Borrower after the date hereof, such information is clearly identified
at the time of delivery as  confidential.  Any Person  required to maintain  the
confidentiality  of  Information as provided in this Section shall be considered
to have complied  with its  obligation to do so if such Person has exercised the
same degree of care to maintain the  confidentiality of such Information as such
Person would accord to its own confidential information.

         SECTION  10.13.  Currency  Indemnity.  (a) If any amount payable by any
Borrower under or in connection with any Loan or any other  obligation  under or
in  connection  herewith is received by any Lender in a currency  (the  "Payment
Currency")  other than that agreed to be payable in this  Agreement (the "Agreed
Currency"),  whether as a result of any judgment or order or the  enforcement of
the same, the  liquidation of such Borrower or otherwise and the amount produced
by  converting  the Payment  Currency so  received  into the Agreed  Currency at
market rates  prevailing at or about the time of receipt of the Payment Currency
is less than the amount of the Agreed  Currency  due with  respect to such Loan,
then such Borrower and the Company shall and hereby does, as an independent  and
additional  obligation,  indemnify  each Lender for the  deficiency and any loss
sustained as a result.

                  (b)  The  above  indemnity  shall   constitute   separate  and
independent  obligations of each Borrower from its other  obligations under this
Agreement  and  shall  apply  irrespective  of  any  indulgence  granted  by the
Administrative Agent or any Lender. The applicable Borrower shall pay reasonable
costs of making any conversion from the Payment Currency to the Agreed Currency.

                  (c) Each  Borrower  hereby waives any right it may have in any
jurisdiction  to pay any amount due and owing hereunder in a currency other than
that which it is expressed to be payable under the terms and  conditions of this
Agreement.

         SECTION 10.14. Subsidiary Borrower Several Obligations. The obligations
of each Subsidiary  Borrower under this Agreement are several and the failure of
any Subsidiary  Borrower to perform its  obligations  under this Agreement shall
not affect the  obligations of any Borrower  towards any of the other parties to
this Agreement.

                  (b) No  assurance,  security  or payment  which may be avoided
under any laws relating to  bankruptcy,  insolvency or corporate  reorganization
and no release, settlement or discharge of any of the Subsidiary Borrowers which
may have been  given or made on the  faith of any such  assurance,  security  or
payment,  shall prejudice or affect the right of the Administrative Agent or any
Lender to recover from any other  Subsidiary  Borrower to the full extent of its
obligations  under  this  Agreement  just  as if  such  release,  settlement  or
discharge had not occurred.

                  (c) Each  Subsidiary  Borrower hereby waives any rights it may
have under applicable law which may at any time be inconsistent  with any of the
provisions  of this  Agreement  or  which it may  have of  first  requiring  the
Administrative  Agent or any Lender to proceed  against  or claim  payment  from
another Borrower or any other party or parties. It is further agreed that all or
any of the  Administrative  Agent and the Lenders,  without notice to any of the
Subsidiary  Borrowers and without affecting or impairing the obligations of such
Subsidiary  Borrowers  hereunder,  may  grant  time,  indulgences,  concessions,
releases and  discharges  to, may take  securities  from and give the same,  may
accept compositions from and may otherwise deal with each other Borrower and all
other  parties as they may see fit and  generally may otherwise do or omit to do
any act or thing  which,  but for this  provision,  might  operate  to affect or
impair  the  obligations  of each of the  Subsidiary  Borrowers  hereunder.  The
obligations  of the  Subsidiary  Borrowers  hereunder  shall not be  affected or
impaired by any amendment or modification hereto.

         SECTION 10.15.  Joint and Several  Obligations of the Company.  (a) The
liability  of  the  Company  under  this  Agreement  with  respect  to  its  own
obligations and the obligations of each Subsidiary Borrower is joint and several
and therefore,  without prejudice to any other provision of this Agreement,  the
Company hereby unconditionally and irrevocably undertakes, as principal obligor,
to  the  Administrative   Agent  and  the  Lenders  the  due  and  unconditional
performance  and discharge by each of the other Borrowers of all the obligations
expressed to be binding upon such Borrowers hereunder as the same may be amended
from time to time (the "Relevant  Obligations") and, without limitation,  agrees
with the  Administrative  Agent and the Lenders that if and whenever at any time
and from  time to time any of the  other  Borrowers  shall  fail to  perform  or
discharge  or shall  otherwise  be in default in respect of any of the  Relevant
Obligations it shall discharge and make good the default as if it instead of the
relevant other Borrower was expressed to be such Borrower hereunder.

                  (b) No  assurance,  security  or payment  which may be avoided
under any laws relating to  bankruptcy,  insolvency or corporate  reorganization
and no release, settlement or discharge of any of the Subsidiary Borrowers which
may have been  given or made on the  faith of any such  assurance,  security  or
payment,  shall prejudice or affect the right of the Administrative Agent or any
Lender to recover from the Company to the full extent of the undertakings  given
in this Section 10.15 just as if such  release,  settlement or discharge had not
occurred.

                  (c) The  Company  hereby  waives  any rights it may have under
applicable law which may at any time be inconsistent  with any of the provisions
of this  Agreement or which it may have of first  requiring  the  Administrative
Agent or any Lender to proceed against or claim payment from another Borrower or
any  other  party  or  parties.  It is  further  agreed  that  all or any of the
Administrative Agent and the Lenders,  without notice to the Company and without
affecting or impairing the obligations of the Company hereunder, may grant time,
indulgences,  concessions,  releases and discharges to, may take securities from
and give the same, may accept compositions from and may otherwise deal with each
other  Borrower  and all other  parties  as they may see fit and  generally  may
otherwise do or omit to do any act or thing which, but for this provision, might
operate  to affect or impair  the  obligations  of the  Company  hereunder.  The
obligations  of the Company  hereunder  shall not be affected or impaired by any
amendment or modification hereto.

                  (d) The Company hereby waives notice of the acceptance of this
undertaking  and of  presentment,  demand and protest and notices of non-payment
and dishonor and any other demands and notices required by applicable law.

         SECTION  10.16.  Interest  Rate  Limitation.  Notwithstanding  anything
herein to the contrary, if at any time the interest rate applicable to any Loan,
together with all fees,  charges and other amounts which are treated as interest
on such Loan under applicable law (collectively the "Charges"), shall exceed the
maximum lawful rate (the "Maximum Rate") which may be contracted  for,  charged,
taken,  received or reserved by the Lender holding such Loan in accordance  with
applicable law, the rate of interest  payable in respect of such Loan hereunder,
together with all Charges  payable in respect  thereof,  shall be limited to the
Maximum Rate and, to the extent lawful, the interest and Charges that would have
been  payable in  respect  of such Loan but were not  payable as a result of the
operation  of this  Section  shall be  cumulated  and the  interest  and Charges
payable to such Lender in respect of other Loans or periods  shall be  increased
(but not above the Maximum Rate therefor) until such cumulated amount,  together
with  interest  thereon  at the  Federal  Funds  Effective  Rate to the  date of
repayment, shall have been received by such Lender.

                  SECTION 10.17. International Banking Facilities. Each Borrower
acknowledges  by its  execution  and delivery  hereof (or by its  execution  and
delivery of any applicable  Joinder  Agreement) that (a) it is the policy of the
Board that deposits  received by  international  banking  facilities may be used
only  to  support  the  non-U.S.  operations  of a  depositor  (or  its  foreign
affiliates)  located  outside the United States and that extensions of credit by
international  banking  facilities  may be used  only to  finance  the  non-U.S.
operations of a Borrower (or its foreign  affiliates)  located  outside the U.S.
and (b) funds deposited by any Borrower with an  international  banking facility
of any Lender will be used  solely in support of such  non-U.S.  operations,  or
that of such foreign  affiliates,  and that the proceeds of any Borrowings  from
any such  international  banking  facility  will be used solely to finance  such
non-U.S.  operations, or that of such foreign affiliates. Any terms used in this
Section  10.17 that are not  otherwise  defined  herein,  shall have the meaning
assigned thereto in Regulation D of the Board (as amended from time to time).

         For purposes of the foregoing, (a) if the Ratings established or deemed
to have been established by Moody's,  Duff & Phelps, and S&P for the Rating Debt
shall fall within  different  Levels,  the Applicable Rate shall be based on the
two highest Ratings; provided, that if such two highest Ratings also fall within
different  Levels,  (i) where the split  represents  one subgrade the Applicable
Rate will be  determined  based on the lower of such two Levels;  and (ii) where
the  split  represents  two or  more  subgrades,  the  Applicable  Rate  will be
determined  by reference  to the Level at the midpoint of such highest  ratings;
provided,  that if such midpoint falls between Levels,  the Applicable Rate will
be determined by reference to the Level immediately below such midpoint;  (b) if
the Ratings  established or deemed to have been  established by Moody's,  Duff &
Phelps,  and S&P for the Rating Debt shall be changed (other than as a result of
a change in the rating system of Moody's,  Duff & Phelps,  or S&P),  such change
shall  be  effective  as of the  date on  which  it is  first  announced  by the
applicable Rating Agency;  (c) if Moody's,  Duff & Phelps, or S&P shall not have
in  effect  a  Rating  for  the  Rating  Debt  (other  than  by  reason  of  the
circumstances  referred to in the last  sentence of this  paragraph),  then such
Rating  Agency  shall be  deemed to have  established  a Rating in Level 6. Each
change in the  Applicable  Rate shall apply during the period  commencing on the
effective date of such change and ending on the date  immediately  preceding the
effective date of the next such change. If the rating system of Moody's,  Duff &
Phelps,  or S&P shall change,  or if any such Rating Agency shall cease to be in
the business of rating corporate debt  obligations,  the Company and the Lenders
shall  negotiate in good faith to amend this  definition to reflect such changed
rating  system or the  unavailability  of Ratings  from such Rating  Agency and,
pending the  effectiveness  of any such amendment,  the Applicable Rate shall be
determined  by  reference  to the Rating most  recently in effect  prior to such
change or cessation. Notwithstanding the foregoing, if on the Effective Date, at
least two of the Rating  Agencies  have not  announced a Rating  expressly to be
effective  after the Oryx  Merger,  Level  Three  pricing  shall  apply from the
Effective  Date until at least two of the Rating  Agencies  shall have announced
such Ratings.

                        OPINION OF RUSSELL G. HORNER, JR.



                                                             February 26, 1999



To the Lenders and the Administrative
  Agent Referred to Below
c/o Royal Bank of Canada, as
  Administrative Agent

Dear Sirs:

                  I have acted as counsel for Kerr-McGee Corporation, a Delaware
corporation  (the  "Company")  and each  Subsidiary  Borrower (as defined in the
following  described  Credit  Agreement),  in connection  with the  $250,000,000
364-Day  Revolving  Credit  Agreement dated as of February 26, 1999 (the "Credit
Agreement"),  among the Company, the Subsidiary  Borrowers,  the banks and other
financial institutions  identified therein as Lenders, and Royal Bank of Canada,
as Administrative  Agent.  Terms defined in the Credit Agreement are used herein
with the same meanings.

                  I have  examined  originals or copies,  certified or otherwise
identified  to  my   satisfaction,   of  such  documents,   corporate   records,
certificates of public  officials and other  instruments and have conducted such
other investigations of fact and law as I have deemed necessary or advisable for
purposes of this opinion.

                  Upon the basis of the foregoing, I am of the opinion that:

                  1. The Company is a  corporation  duly  incorporated,  validly
existing  and in good  standing  under the laws of the State of  Delaware.  Each
Domestic  Subsidiary  Borrower  organized under the laws of the United States of
America,  any State thereof, or the District of Columbia,  is a corporation duly
incorporated,  validly  existing  and in good  standing  (or,  if such  Domestic
Subsidiary  Borrower  is a limited  liability  company,  is a limited  liability
company duly formed,  validly  existing and in good standing)  under the laws of
its  jurisdiction  of  incorporation,  organization  or formation.  Each Foreign
Subsidiary Borrower organized under the laws of a jurisdiction other than United
States of America, any State thereof, or the District of Columbia,  is a company
duly  established  and validly  existing under the laws of its  jurisdiction  of
formation.

                  2.  The  Company  and  each  Subsidiary  Borrower  (a) has all
requisite corporate or limited liability company power and authority to carry on
its  business  as now  conducted,  and (b)  except  where the  failure to do so,
individually or in the aggregate,  could not reasonably be expected to result in
a Material  Adverse  Effect,  is  qualified  to do  business  in, and is in good
standing in, every jurisdiction where such qualification is required.

                  3.  The   Transactions  are  within  the  Company's  and  each
Subsidiary  Borrower's  corporate or limited  liability  company powers and have
been duly authorized by all necessary  corporate or limited  liability  company,
and,  if  required,  stockholder  action.  The  Credit  Agreement  has been duly
executed and delivered by each Borrower.

                  4. The Transactions (a) do not require any consent or approval
of,  registration  or filing  with,  or any other  action by,  any  Governmental
Authority,  except such as have been  obtained or made and are in full force and
effect,  (b) will not violate any  applicable  law or regulation or the charter,
by-laws  or  other  organizational  documents  of  each  Borrower  or any of its
Subsidiaries or any order of any Governmental Authority, (c) will not violate or
result in a default under any indenture,  agreement or other instrument  binding
upon each Borrower or any of its  Subsidiaries or its assets,  or give rise to a
right  thereunder  to require any payment to be made by a Borrower or any of its
Subsidiaries,  and (d) will not result in the creation or imposition of any Lien
on any asset of the Company or any of its Subsidiaries.

                  5. There are no actions, suits or proceedings by or before any
arbitrator  or  Governmental  Authority  pending  against  or, to my  knowledge,
threatened against or affecting the Company or any of its Subsidiaries (a) as to
which there is a reasonable possibility of an adverse determination and that, if
adversely  determined,  could  reasonably  be expected,  individually  or in the
aggregate,  to have a Material  Adverse  Effect or (b) that  involve  the Credit
Agreement or the Transactions.

                  6. Neither the Company nor any of its  Subsidiaries  is (a) an
"investment  company"  as  defined  in, or  subject  to  regulation  under,  the
Investment  Company  Act of 1940 or (b) a "holding  company"  as defined  in, or
subject to regulation under, the Public Utility Holding Company Act of 1935.

                  I am a  member  of the bar of the  State of  Oklahoma  and the
foregoing  opinion is limited to the laws of the State of Oklahoma,  the General
Corporation  Law of the State of  Delaware  and the  Federal  laws of the United
States of America. This opinion is rendered solely to you in connection with the
above  matter.  This opinion may not be relied upon by you for any other purpose
or relied upon by any other Person  (other than your  successors  and assigns as
Lenders and Persons that acquire participations in your Loans) without our prior
written consent.


                                                     Very truly yours,

                                     FORM OF
                      OPINION OF SIMPSON THACHER & BARTLETT


                                                         February 26, 1999


Royal    Bank of Canada, as Administrative Agent under the Credit Agreement,  as
         hereinafter defined (the "Agent")

         and

The      Lenders  listed on  Schedule I hereto  which are  parties to the Credit
         Agreement on the date hereof

Ladies and Gentlemen:

         We have acted as counsel to Kerr-McGee  Corporation (the "Company") and
the  subsidiaries  of the Company named on Schedule II attached  hereto (each, a
"Subsidiary Borrower" and, collectively, the "Subsidiary Borrowers"; the Company
and the  Subsidiary  Borrowers  being  referred  to herein  collectively  as the
"Credit Parties") in connection with the preparation,  execution and delivery of
the  $250,000,000  364-Day  Revolving  Credit Agreement dated as of February 26,
1999 (the "Credit Agreement") among the Company, the Subsidiary  Borrowers,  the
lending institutions  identified in the Credit Agreement (the "Lenders") and the
Agent. Unless otherwise indicated, capitalized terms used but not defined herein
shall  have the  respective  meanings  set forth in the Credit  Agreement.  This
opinion is furnished to you pursuant to Section 4.01(c) of the Credit Agreement.

         In connection with this opinion, we have examined the Credit Agreement,
signed by each Credit Party thereto and by the Agent and certain of the Lenders.
We also have  examined the  originals,  or  duplicates or certified or conformed
copies,  of such records,  agreements,  instruments and other documents and have
made such other  investigations  as we have deemed  relevant  and  necessary  in
connection with the opinions  expressed herein. As to questions of fact material
to this opinion,  we have relied upon  certificates  of public  officials and of
officers  and  representatives  of the  Credit  Parties.  In  addition,  we have
examined,  and have relied as to matters of fact upon, the representations  made
in the Credit Agreement.
         In  rendering  the  opinions  set  forth  below,  we have  assumed  the
genuineness  of all  signatures,  the legal  capacity  of natural  persons,  the
authenticity  of all documents  submitted to us as originals,  the conformity to
original  documents of all documents  submitted to us as duplicates or certified
or  conformed  copies,  and the  authenticity  of the  originals  of such latter
documents.
         Based  upon  and  subject  to  the   foregoing,   and  subject  to  the
qualifications and limitations set forth herein, we are of the opinion that:
         1. Assuming that proceeds of borrowings will be used in accordance with
the terms of the Credit  Agreement,  the  execution  and  delivery by any Credit
Party of the Credit  Agreement,  its borrowings in accordance  with the terms of
the Credit Agreement and performance of its payment obligations  thereunder will
not result in any  violation of any New York  statute or any rule or  regulation
issued pursuant to any New York statute.

         2. No consent, approval, authorization,  order, filing, registration or
qualification  of or with any New York  governmental  agency is required for the
execution  and  delivery  by any  Credit  Party of the Credit  Agreement  or the
borrowings  by any  Credit  Party in  accordance  with the  terms of the  Credit
Agreement.

         3.  Assuming that the Credit  Agreement is a valid and legally  binding
obligation  of each of the Lenders  party  thereto and assuming that (a) each of
the Credit  Parties is validly  existing and in good standing  under the laws of
the jurisdiction in which it is organized and has duly authorized,  executed and
delivered  the  Credit   Agreement  in  accordance   with  its   Certificate  of
Incorporation  and By-Laws,  (b)  execution,  delivery and  performance  by each
Credit Party of the Credit Agreement do not violate the laws of the jurisdiction
in which it is organized or any other applicable laws (excepting the laws of the
State of New York), (c) execution, delivery and performance by each Credit Party
of the Credit Agreement do not constitute a breach or violation of any agreement
or instrument which is binding upon such Credit Party and (d) no Credit Party is
an "investment  company"  within the meaning of and subject to regulation  under
the Investment  Company Act of 1940, the Credit Agreement  constitutes the valid
and legally binding  obligation of each Credit Party,  enforceable  against such
Credit Party in accordance with its terms.

         Our  opinions  in  paragraph  3 above are subject to (i) the effects of
bankruptcy,  insolvency, fraudulent conveyance,  reorganization,  moratorium and
other similar laws relating to or affecting  creditors' rights  generally,  (ii)
general equitable principles (whether considered in a proceeding in equity or at
law),  (iii) an implied  covenant  of good faith and fair  dealing  and (iv) the
effects  of the  possible  judicial  application  of  foreign  laws  or  foreign
governmental or judicial action affecting creditors' rights.
         We note that (A) a New York  statute  provides  that with  respect to a
foreign  currency  obligation  a court of the State of New York  shall  render a
judgment or decree in such foreign currency and such judgment or decree shall be
converted into currency of the United States at the rate of exchange  prevailing
on the  date of entry of such  judgment  or  decree  and (B) with  respect  to a
foreign currency  obligation a United States Federal court in New York may award
judgment in United States dollars, provided that we express no opinion as to the
rate of exchange such court would apply.
         We express no opinion with respect to:
         (A) the  effect  of any  provision  of the  Credit  Agreement  which is
intended to permit modification  thereof only by means of an agreement signed in
writing by the parties thereto;
         (B) the effect of any provision of the Credit  Agreement  insofar as it
provides  that any  Person  purchasing  a  participation  from a Lender or other
Person may exercise set-off or similar rights with respect to such participation
or that any Lender or other Person may exercise  set-off or similar rights other
than in accordance with applicable law;
         (C) the  effect  of any  provision  of the  Credit  Agreement  imposing
         penalties or forfeitures;  (D) the  enforceability  of any provision of
         the Credit Agreement to the extent that such provision
constitutes  a waiver of  illegality  as a defense to  performance  of  contract
obligations; (E) the effect of any provision of the Credit Agreement relating to
indemnification  or exculpation in connection  with violations of any securities
laws or relating to  indemnification,  contribution or exculpation in connection
with willful,  reckless or criminal acts or gross  negligence of the indemnified
or exculpated Person or the Person receiving contribution.; and
         (F) the effect of any  provision  of the Credit  Agreement  whereby the
Credit Parties submit to the  jurisdiction  of the United States  District Court
for the Southern  District of New York or the Supreme  Court of the State of New
York.

         We are  members  of the Bar of the  State  of New  York,  and we do not
express any opinion herein concerning any law other than the law of the State of
New York.
         This  opinion  letter is rendered to you in  connection  with the above
described  transactions.  This opinion  letter may not be relied upon by you for
any other  purpose,  or relied  upon by any other  person,  firm or  corporation
without our prior written consent.

                                                     Very truly yours,

                                      Dated as of  [                  ]







         THIS CASH COLLATERAL  ACCOUNT AGREEMENT (this  "Agreement") is made and
entered  into as of the __ day of _______,  ____,  [between][among]  [KERR-McGEE
CORPORATION, a Delaware corporation (the "Company"), [______________________,  a
____________________   ("  "),]]  and  ROYAL   BANK  OF   CANADA   ("RBC"),   as
administrative agent (in such capacity,  the "Administrative  Agent") for itself
and the Lenders (as defined in the Credit Agreement referred to below).

                                    RECITALS

         A. On February 26, 1999,  the Company,  the  Subsidiary  Borrowers  (as
defined in the  Credit  Agreement),  the  Administrative  Agent and the  Lenders
executed that certain  Revolving Credit Agreement (as amended from time to time,
the "Credit Agreement")  whereby,  upon the terms and conditions stated therein,
the Lenders agreed to make Loans (as defined in the Credit Agreement) (a) to the
Company  and  the  Domestic  Subsidiary  Borrowers  (as  defined  in the  Credit
Agreement) or any one or more of them, up to the Domestic  Available  Amount (as
defined in the Credit Agreement) and (b) to the Foreign Subsidiary Borrowers (as
defined in the Credit  Agreement)  or any one or more of them up to the  Foreign
Available Amount (as defined in the Credit Agreement).

         B. Section 2.08(c) of the Credit  Agreement  provides that in the event
that (i) the aggregate principal amount of all Loans made to the Company and the
Domestic Subsidiary  Borrowers exceeds the Domestic Available Amount or (ii) the
aggregate  amount of all Loans made to the Company  and the  Foreign  Subsidiary
Borrowers exceeds the Foreign  Available Amount,  the Company may, and may cause
one of more of the  Subsidiary  Borrowers  to, in lieu of prepaying  such excess
described  in clause (i) or (ii) above,  provide  cash  collateral  equal to the
amount of such  excess  plus any accrued  and unpaid  interest  thereon,  to the
Administrative  Agent for the benefit of the  Lenders  pursuant to the terms and
conditions of this Agreement.

         C.  Therefore,  in accordance  with the terms of Section 2.08(c) of the
Credit Agreement, and for other good and valuable consideration, the receipt and
sufficiency  of which are hereby  acknowledged,  [the  Company  and  [Subsidiary
Borrower]] hereby [agrees][agree] and with the Administrative Agent as follows:

                                    AGREEMENT

         Section  (1)  Pursuant  to Section  2.08(c)  of the  Credit  Agreement,
simultaneously   with  the  execution  of  this  Agreement,   [the  Company  and
[Subsidiary Borrower]] will make [a deposit][deposits] in an amount equal to the
excess as  determined  in accordance  with Section  2.08(c)[(ii)][(iii)]  of the
Credit  Agreement  plus all  accrued  and  unpaid  interest  thereon  (the "Cash
Collateral")  in an account with the  Administrative  Agent,  in the name of the
Administrative  Agent and for the benefit of the Lenders styled "Kerr-McGee Cash
Collateral  Account,"  which is an interest  bearing  collateral  account and is
subject to the exclusive dominion and control,  including the exclusive right of
withdrawal, of the Administrative Agent (the "Cash Collateral Account").

         Section   (2)  [The   Company   and   [Subsidiary   Borrower]]   hereby
[pledge][pledges]  and  [grant][grants]  to the  Administrative  Agent  for  the
account of the Lenders a security  interest in the Cash  Collateral and the Cash
Collateral  Account to secure the payment and  performance of the obligations of
the Company and the Subsidiary Borrowers under the Credit Agreement.


         Section (3)

                  (a) The Cash Collateral may be invested by the  Administrative
         Agent at the option and sole discretion of the Administrative Agent and
         at the risk and  expense of [the  Company and  [Subsidiary  Borrower]].
         Interest or profits,  in any, on such  investments  shall accumulate in
         the  Cash  Collateral  Account.  Other  than  interest  earned  on such
         investments, the Cash Collateral shall not bear interest. Moneys in the
         Cash Collateral Account shall be applied by the Administrative Agent to
         satisfy the  obligations  of the Company and the  Subsidiary  Borrowers
         under the Credit Agreement.

                  (b) Moneys in the Cash Collateral Account shall be returned to
         [the Company and  [Subsidiary  Borrower]]  within three  Business  Days
         after the  earlier  to occur of (i) the first  Business  Day of a month
         that the Administrative Agent determines that the Cash Collateral is no
         longer required pursuant to Section  2.08(c)[(ii)][(iii)] of the Credit
         Agreement  and (ii) a prepayment of the Loans in an amount equal to the
         Cash Collateral.  In such event, the Administrative  Agent will execute
         and deliver to [the Company and  [Subsidiary  Borrower]] an appropriate
         release  of the  pledge,  liens,  security  interests  and  obligations
         created  hereby  and  will  release  to [the  Company  and  [Subsidiary
         Borrower]] all funds then remaining in the Cash Collateral Account.

         Section (4) [The Company and [subsidiary borrower]]  [agrees][agree] to
reimburse  and  indemnify  the  Administrative  Agent  for and hold it  harmless
against  any  loss,  liability,  claim,  demand,  cause of  action,  damages  or
controversy at any time arising out of or in connection with  performance by the
Administrative  Agent of any of its duties and obligations under this Agreement,
as well as all costs and  expenses,  including  but not  limited  to  reasonable
attorneys' fees, incurred in the administration or preparation of this Agreement
or in  defending  against any claim or  liability  arising out of or relating to
this Agreement other than arising out of or relating to the wilful misconduct or
gross negligence of the Administrative Agent.

         Section (5) [The Company and  [Subsidiary  Borrower]]  will promptly at
[its][their] sole expense, upon reasonable request, execute and deliver all such
other   documents  in  form  and  substance   reasonably   satisfactory  to  the
Administrative  Agent and its legal counsel and take such other action as may be
reasonable  and  necessary  to fully  effectuate  the terms  and  intent of this
Agreement.

         Section 7. In the event that one or more of the provisions contained in
this Agreement shall, for any reason, be held invalid,  illegal or unenforceable
in any respect (i) [the Company and [Subsidiary Borrower]]  [agrees][agree] that
such  invalidity,  illegality  or  unenforceability  shall not  affect any other
provision of this Agreement,  and (ii) [the Company,] [ Subsidiary Borrower] and
Administrative  Agent  (acting on behalf of and at the direction of the Lenders)
will  negotiate in good faith to amend such  provision so as to be legal,  valid
and enforceable.

         Section 8. This Agreement may be executed in counterparts, and it shall
not be necessary  that the  signatures of all parties hereto be contained on any
one counterpart hereof; each counterpart shall be deemed an original, but all of
which together shall constitute one and the same instrument.



         WITNESS THE EXECUTION HEREOF, as of the date first above written.

To Kerr-McGee Corporation:

         We  have  examined  the   consolidated   balance  sheet  of  Kerr-McGee
Corporation (a Delaware corporation) and subsidiary companies as of December 31,
____ and ____,  and the  related  consolidated  statements  of income,  retained
earnings and cash flows for each of the three years in the period ended December
31,  ____ and have  issued our report  thereon  dated  February  __,  ____.  Our
examination was made in accordance with generally  accepted  auditing  standards
and,  accordingly,  included such tests of the accounting records and such other
auditing procedures as we considered necessary in the circumstances.

         We have read the Credit  Agreement  dated as of February 26, 1999 among
Kerr-McGee  Corporation (the  "Company"),  the lenders parties thereto and Royal
Bank of Canada, as Administrative Agent (as amended, modified,  supplemented and
restated from time to time, the "Credit Agreement"), particularly Articles V, VI
and VII.  These  articles  contain  certain  covenants  of the  Company  and the
Subsidiary  Borrowers  relative to certain  financial  conditions  and  describe
Events of Default relative to such covenants. We have also read the accompanying
officer's  certificate  prepared by your chief accounting  officer  described in
Section 5.01(c) of the Credit Agreement.

         In connection with our examination,  nothing came to our attention that
caused us to believe  that you were in  default  with any of the  provisions  of
Article  VII of the  Credit  Agreement  insofar as they  pertain  to  accounting
matters.  It should be noted that our  examination  was not  directed  primarily
toward obtaining knowledge of noncompliance.

                                                       Very truly yours,

                                   The Credits

         SECTION  2.01.  Commitments.  Subject to the terms and  conditions  set
forth herein,  each Lender  severally  agrees to make Revolving Loans (a) to the
Company and the Domestic Subsidiary  Borrowers or any one or more of them, up to
the Domestic Available Amount,  and (b) to the Foreign  Subsidiary  Borrowers or
any one or more of them, up to the Foreign Available  Amount,  from time to time
during the  Availability  Period in an aggregate  principal amount that will not
result in (i) such Lender's  Revolving  Credit Exposure  exceeding such Lender's
Commitment  or (ii) the sum of the total  Revolving  Credit  Exposures  plus the
aggregate principal amount of outstanding  Competitive Loans exceeding the total
Commitments. Within the foregoing limits and subject to the terms and conditions
set forth herein,  any Borrower may make more than one Borrowing on any Business
Day and may borrow, prepay and reborrow Revolving Loans.

         SECTION 2.02.  Loans and  Borrowings.  (a) Each Revolving Loan shall be
made as part of a Borrowing  consisting  of Revolving  Loans made by the Lenders
ratably in accordance with their respective  Commitments.  Each Competitive Loan
shall be made in accordance  with the  procedures set forth in Section 2.04. The
failure  of any  Lender  to make any Loan  required  to be made by it shall  not
relieve  any  other  Lender  of its  obligations  hereunder;  provided  that the
Commitments and Competitive  Bids of the Lenders are several and no Lender shall
be responsible for any other Lender's failure to make Loans as required.

                  (b)  Subject to Section  2.12,  (i) each  Revolving  Borrowing
shall be made entirely in LIBOR Loans,  EURIBOR Loans, CD Loans or ABR Loans, as
the  Company  may  request in  accordance  herewith;  and (ii) each  Competitive
Borrowing  shall  be made  (A) in the  case of  Dollar  Competitive  Borrowings,
entirely  in LIBOR  Loans or Fixed Rate  Loans and (B) in the case of  Alternate
Currency  Competitive  Borrowings,  entirely in LIBOR Loans or EURIBOR Loans, as
the Company may request in accordance herewith.  Each Lender, at its option, may
make any LIBOR Loan or EURIBOR Loan by causing any domestic or foreign branch or
Affiliate of such Lender to make such Loan;  provided  that any exercise of such
option shall not affect the obligation of a Borrower to repay such Loans made to
it in accordance  with the terms of this  Agreement;  and provided  further that
each Lender shall have an office, or a branch,  or an Affiliate  available to it
and located in the appropriate  jurisdiction  through which such Lender can make
any Eurodollar Loan or any Loan denominated in an Alternate Currency as required
under this Agreement.

                  (c) At the  commencement  of each initial  Interest Period for
(i) any Revolving Borrowing comprised of LIBOR Loans, EURIBOR Loans or CD Loans,
such Borrowing shall be in an aggregate  amount that is an integral  multiple of
1,000,000 units of the applicable  currency thereof and not less than 10,000,000
units of such currency.  At the time that each Revolving  Borrowing comprised of
ABR Loans is made,  such  Borrowing  shall be in an aggregate  amount that is an
integral  multiple of $1,000,000  and not less than  $10,000,000;  provided that
such ABR Revolving  Borrowing may be in an aggregate amount that is equal to the
entire unused balance of the Domestic  Available Amount or the Foreign Available
Amount,  as  applicable.  Each  Competitive  Borrowing  shall be in an aggregate
amount  that is an  integral  multiple  of  1,000,000  units  of the  applicable
currency thereof and not less than 10,000,000 units of such currency. Borrowings
of more than one Type and Class may be  outstanding  at the same time;  provided
that  there  shall  not at any time be more than a total of 10 CD,  EURIBOR  and
LIBOR Revolving Borrowings outstanding.

                  (d) Notwithstanding any other provision of this Agreement, the
Company, on behalf of itself or any Borrower,  shall not be entitled to request,
or to elect to  convert  or  continue,  any  Borrowing  if the  Interest  Period
requested with respect thereto would end after the Maturity Date.

         SECTION 2.03. Requests for Revolving Borrowings. To request a Revolving
Borrowing,  the Company shall notify the Administrative Agent of such request by
hand delivery or telecopy of a Borrowing Request or by telephone (a) in the case

telephonic  Borrowing  Request  shall be  irrevocable  and  shall  be  confirmed

         "Interest Period"; and

                  (vii) the  location  and number of the  applicable  Borrower's
         account to which funds are to be disbursed, which shall comply with the
         requirements of Section 2.05.

If no election as to the Type of any Revolving Borrowing  denominated in Dollars
is specified,  then the requested Revolving Borrowing shall be an ABR Borrowing.
If no Interest  Period is specified with respect to any requested CD, EURIBOR or
LIBOR Revolving Borrowing,  then the Company shall be deemed to have selected an
Interest  Period of 30 days'  duration,  in the case of a CD  Borrowing,  or one
month's duration, in the case of a EURIBOR Borrowing or a LIBOR Borrowing. If no
election as to the  currency of the  Borrowing  is  specified,  then the Company
shall be deemed to have  selected  Dollars;  provided  that in no event  shall a
Borrowing deemed to be denominated in Dollars bear interest at a rate other than
the Adjusted  Eurodollar  LIBO Rate,  the Adjusted CD Rate or the Alternate Base
Rate.  Promptly following receipt of a Borrowing Request in accordance with this
Section,  the  Administrative  Agent  shall  advise  each  Lender of the details
thereof  and of the  amount  of  such  Lender's  Loan  to be made as part of the
requested Borrowing.

         SECTION 2.04.  Competitive Bid Procedure.  (a) Subject to the terms and
conditions set forth herein,  from time to time during the  Availability  Period
the  Company  may  request  Competitive  Bids  and may (but  shall  not have any
obligation to) accept Competitive Bids and borrow  Competitive  Loans;  provided

the Revolving Credit Exposures attributable to such Borrowers plus the aggregate
principal  amount  of  outstanding  Competitive  Loans at any time  made to such
Borrowers shall not exceed the Foreign Available Amount. To request  Competitive

delivery or telecopy of a competitive Borrowing Request or by telephone,  in the
case of (w) a  Eurodollar  Borrowing,  not later than 11:00 a.m.,  New York City
time,  four  Business  Days  before the date of the  proposed  Borrowing,  (x) a

written  Competitive Bid Request in a form approved by the Administrative  Agent
and signed by the Company.  Each such  telephonic  and written  Competitive  Bid
Request shall specify the following information in compliance with Section 2.02:

         Currency, which Alternate Currency;

                  (v) whether such Borrowing is to be a Fixed Rate Borrowing,  a

                  (vi) the Interest  Period to be applicable to such  Borrowing,
         which  shall be a period  contemplated  by the  definition  of the term
         "Interest Period"; and

                  (vii) the  location  and number of the  applicable  Borrower's

                  (b) Each  Lender  may (but shall not have any  obligation  to)
make one or more  Competitive  Bids to the Company in response to a  Competitive
Bid Request.  Each Competitive Bid by a Lender must be in a form approved by the
Administrative  Agent  and  must be  received  by the  Administrative  Agent  by
telecopy, (i) in the case of a Eurodollar Competitive Borrowing,  not later than

Administrative   Agent  shall  notify  the  applicable  Lender  as  promptly  as
practicable.  Each Competitive Bid shall specify (i) the principal amount (which
shall be a  minimum  of  10,000,000  units  of the  applicable  currency  and an
integral  multiple of 1,000,000  units of such  currency and which may equal the
entire principal amount of the Competitive Borrowing requested by the Company on

Competitive Bid.

                  (d) Subject  only to the  provisions  of this  paragraph,  the
Company  may accept or reject any  Competitive  Bid on behalf of any  applicable
Borrower.  The  Company  shall  notify the  Administrative  Agent by  telephone,
confirmed by telecopy in a form approved by the  Administrative  Agent,  whether
and to what extent it has decided to accept or reject each  Competitive Bid, (i)
in the case of a Eurodollar  Competitive  Borrowing,  not later than 10:30 a.m.,
New York  City  time,  three  Business  Days  before  the  date of the  proposed
Competitive  Borrowing,  (ii)  in  the  case  of a  Sterling  LIBOR  Competitive
Borrowing or a EURIBOR  Competitive  Borrowing,  not later than 10:30 a.m.,  New
York City time,  four Business Days before the date of the proposed  Competitive
Borrowing, and (iii) in the case of a Fixed Rate Borrowing, not later than 10:30
a.m.,  New York City time,  on the proposed date of the  Competitive  Borrowing;
provided that (i) the failure of the Company to give such notice shall be deemed
to be a rejection of each  Competitive  Bid, (ii) the Company shall not accept a
Competitive Bid made at a particular Competitive Bid Rate if the Company rejects
a  Competitive  Bid made at a lower  Competitive  Bid Rate,  (iii) the aggregate
amount of the  Competitive  Bids  accepted by the  Company  shall not exceed the
aggregate amount of the requested Competitive Borrowing specified in the related
Competitive  Bid  Request,  (iv) to the extent  necessary  to comply with clause
(iii) above, the Company may accept Competitive Bids at the same Competitive Bid
Rate in part, which acceptance, in the case of multiple Competitive Bids at such
Competitive  Bid Rate,  shall be made pro rata in accordance  with the amount of
each such  Competitive  Bid,  and (v) except  pursuant to clause (iv) above,  no
Competitive Bid shall be accepted for a Competitive Loan unless such Competitive
Loan is in a minimum  principal  amount of  10,000,000  units of the  applicable
currency and an integral multiple of 1,000,000 units of such currency;  provided
further  that if a  Competitive  Loan must be in an amount less than  10,000,000
units of the applicable currency because of the provisions of clause (iv) above,
such  Competitive  Loan may be for a minimum of 1,000,000 units of such currency
or any integral multiple thereof,  and in calculating the pro rata allocation of
acceptances of portions of multiple Competitive Bids at a particular Competitive
Bid Rate  pursuant  to clause  (iv) the  amounts  shall be rounded  to  integral
multiples of 1,000,000 units of the applicable  currency in a manner  determined
by the Company.  A notice given by the Company  pursuant to this paragraph shall
be irrevocable with respect to the Company and any applicable Borrower.

                  (e)  The  Administrative  Agent  shall  promptly  notify  each
bidding Lender by telecopy  whether or not its Competitive Bid has been accepted
(and,  if so,  the  amount  and  Competitive  Bid  Rate so  accepted),  and each
successful  bidder  will  thereupon  become  bound,  subject  to the  terms  and
conditions  hereof,  to make  the  Competitive  Loan in  respect  of  which  its
Competitive Bid has been accepted.

                  (f) If the  Administrative  Agent  shall  elect  to  submit  a
Competitive  Bid in its capacity as a Lender,  it shall submit such  Competitive
Bid  directly to the Company at least one  quarter of an hour  earlier  than the
time by which the other Lenders are required to submit their Competitive Bids to
the Administrative Agent pursuant to paragraph (b) of this Section.

         SECTION 2.05.  Funding of  Borrowings.  (a) Each Lender shall make each
Loan to be made by it hereunder on the proposed date thereof by wire transfer of
immediately  available  funds by 12:00 noon,  New York City time, in the case of
Dollar  Borrowings,  and by 12:00 noon,  London time,  in the case of Borrowings
denominated in an Alternate  Currency,  to the applicable Agency Account for the
account of the  applicable  Borrower.  The  Administrative  Agent will make such
Loans available to the applicable  Borrower by promptly crediting the amounts so
received,  in like  funds,  to an account  of such  Borrower  designated  by the
Company in the applicable Borrowing Request or Competitive Bid Request.

                  (b) Unless the Administrative Agent shall have received notice
from a Lender prior to the proposed date of any Borrowing  that such Lender will
not make  available  to the  Administrative  Agent such  Lender's  share of such
Borrowing,  the  Administrative  Agent may assume that such Lender has made such
share  available on such date in accordance  with  paragraph (a) of this Section
and may, in reliance  upon such  assumption,  make  available to the  applicable
Borrower a corresponding amount. In such event, if a Lender has not in fact made
its share of the applicable  Borrowing  available to the  Administrative  Agent,
then the applicable Lender and the applicable Borrower severally agree to pay to
the  Administrative  Agent  forthwith on demand such  corresponding  amount with
interest  thereon,  for each day from and including the date such amount is made
available to the applicable Borrower to but excluding the date of payment to the
Administrative  Agent,  at (i) in the case of such  Lender,  the  greater of the
Federal Funds Effective Rate and a rate determined by the  Administrative  Agent
in accordance with banking  industry rules on interbank  compensation or (ii) in
the case of the applicable Borrower,  the interest rate applicable to ABR Loans.
If such Lender pays such amount to the  Administrative  Agent,  then such amount
shall constitute such Lender's Loan included in such Borrowing.

         SECTION  2.06.  Interest   Elections.   (a)  Each  Revolving  Borrowing
initially  shall be of the Type  specified in the applicable  Borrowing  Request
and, in the case of a CD, EURIBOR or LIBOR  Revolving  Borrowing,  shall have an
initial Interest Period as specified in such Borrowing Request.  Thereafter, the
Company may elect to convert such  Borrowing to a different  Type or to continue
such Borrowing and, in the case of a CD, EURIBOR or LIBOR  Revolving  Borrowing,
may elect  Interest  Periods  therefor,  all as  provided in this  Section.  The
Company may elect  different  options with respect to different  portions of the
affected  Borrowing,  in which case each such portion shall be allocated ratably
among the Lenders holding the Loans  comprising  such  Borrowing,  and the Loans
comprising  each such portion  shall be  considered a separate  Borrowing.  This
Section shall not apply to Competitive Borrowings, which may not be converted or
continued.

                  (b) To make an election pursuant to this Section,  the Company
shall  notify the  Administrative  Agent of such  election  by hand  delivery or
telecopy  of an Interest  Election  Request or by  telephone  by the time that a
Borrowing  Request  would be required  under  Section  2.03 if the Company  were
requesting a Revolving  Borrowing of the Type resulting from such election to be
made on the  effective  date of such  election.  Each such  telephonic  Interest
Election  Request shall be irrevocable  and shall be confirmed  promptly by hand
delivery or telecopy to the Administrative  Agent of a written Interest Election
Request  in a form  approved  by the  Administrative  Agent  and  signed  by the
Company.

                  (c) Each  telephonic  and written  Interest  Election  Request
shall specify the following information in compliance with Section 2.02:

                  (i) the  Borrowing  to which such  Interest  Election  Request
         applies  and, if  different  options are being  elected with respect to
         different  portions  thereof,  the portions  thereof to be allocated to
         each resulting Borrowing (in which case the information to be specified
         pursuant to clauses  (iii) and (iv) below shall be  specified  for each
         resulting Borrowing);

                  (ii) the effective  date of the election made pursuant to such
         Interest Election Request, which shall be a Business Day;

                  (iii)  whether  the  resulting  Borrowing  is  to  be  an  ABR
         Borrowing, a CD Borrowing, a EURIBOR Borrowing or a LIBOR Borrowing;

                  (iv) if the resulting  Borrowing is a CD Borrowing,  a EURIBOR
         Borrowing or a LIBOR  Borrowing,  the Interest  Period to be applicable
         thereto after giving effect to such  election,  which shall be a period
         contemplated by the definition of the term "Interest Period".

If any such  Interest  Election  Request  requests  a CD  Borrowing,  a  EURIBOR
Borrowing or a LIBOR Borrowing,  but does not specify an Interest  Period,  then
the Company  shall be deemed to have  selected  an  Interest  Period of 30 days'
duration, in the case of a CD Borrowing, or one month's duration, in the case of
a EURIBOR Borrowing or a LIBOR Borrowing.

                  (d)  Promptly   following  receipt  of  an  Interest  Election
Request,  the  Administrative  Agent  shall  advise  each  Lender of the details
thereof and of such Lender's portion of each resulting Borrowing.

                  (e) If the Company fails to deliver a timely Interest Election
Request with respect to a CD Revolving Borrowing,  a EURIBOR Revolving Borrowing
or a  LIBOR  Revolving  Borrowing  prior  to  the  end of  the  Interest  Period
applicable thereto, then, unless such Borrowing is repaid as provided herein, at
the  end of such  Interest  Period,  (i) if such  Borrowing  is  denominated  in
Dollars,  it shall be converted to an ABR  Revolving  Borrowing and (ii) if such
Borrowing is denominated in an Alternate  Currency,  the Company shall be deemed
to have selected an Interest Period of one month's duration. Notwithstanding any
contrary provision hereof, if an Event of Default has occurred and is continuing
and the  Administrative  Agent,  at the  request  of the  Required  Lenders,  so
notifies the Company,  then, so long as an Event of Default is continuing (i) no
outstanding  Revolving  Borrowing  denominated in Dollars may be converted to or
continued as a CD Borrowing or a LIBOR Borrowing and (ii) unless repaid,  (A) in
the case of Borrowings  denominated in Dollars,  each CD Revolving Borrowing and
each LIBOR Revolving  Borrowing shall be converted to an ABR Revolving Borrowing
at the end of the Interest  Period  applicable  thereto,  and (B) in the case of
Borrowings  denominated in an Alternate Currency, the Company shall be deemed to
have selected an Interest Period of one month's duration.

         SECTION 2.07.  Termination or Reduction of Commitments.

                  (a)  Unless   previously   terminated  the  Commitments  shall
terminate on the Maturity Date.

                  (b) The  Company  may at any time  terminate,  or from time to
time reduce, the Commitments with such reductions applicable in whole or in part
to the Domestic  Available Amount or the Foreign Available Amount, at the option
of the Company;  provided that (i) each reduction of the Commitments shall be in
an  amount  that  is an  integral  multiple  of  $5,000,000  and not  less  than
$20,000,000  and (ii) the Company shall not terminate or reduce the  Commitments
if, after giving effect to any concurrent  prepayment of the Loans in accordance
with  Section  2.09,  (A) the sum of the  Revolving  Credit  Exposures  plus the
aggregate  principal  amount of outstanding  Competitive  Loans would exceed the
total Commitments,  (B) with respect to the Company and the Domestic  Subsidiary
Borrowers,  the  sum of the  Revolving  Credit  Exposures  attributable  to such
Borrowers plus the aggregate  principal amount of outstanding  Competitive Loans
made to such Borrowers would exceed the Domestic  Available Amount, and (C) with
respect to the Foreign  Subsidiary  Borrowers,  the sum of the Revolving  Credit
Exposures  attributable to such Borrowers plus the aggregate principal amount of
outstanding  Competitive  Loans made to such Borrowers  would exceed the Foreign
Available Amount.

                  (c) The Company shall notify the  Administrative  Agent of any
election to  terminate or reduce the  Commitments  under  paragraph  (b) of this
Section  at  least  five  Business  Days  prior  to the  effective  date of such
termination  or  reduction,  specifying  such  election and the  effective  date
thereof.  Promptly  following receipt of any notice,  the  Administrative  Agent
shall advise the Lenders of the contents  thereof.  Each notice delivered by the
Company pursuant to this Section shall be irrevocable; provided that a notice of
termination  of the  Commitments  delivered  by the  Company may state that such
notice is conditioned  upon the  effectiveness  of other credit  facilities,  in
which  case  such  notice  may be  revoked  by the  Company  (by  notice  to the
Administrative  Agent  on or  prior  to the  specified  effective  date) if such
condition is not  satisfied.  Any  termination  or reduction of the  Commitments
shall be  permanent.  Each  reduction of the  Commitments  shall be made ratably
among the Lenders in accordance with their respective Commitments.

         SECTION 2.08.  Repayment of Loans;  Evidence of Debt. (a) Each Borrower
hereby  unconditionally  promises to pay (i) to the Administrative Agent for the
account of each Lender the then unpaid principal amount of each of its Revolving
Loans on the Maturity Date and (ii) to the Administrative  Agent for the account
of each Lender the then unpaid principal amount of each of its Competitive Loans
on the last day of the Interest  Period  applicable to such Loan provided,  that
the Revolving Loans and Competitive  Loans made by a Non-Extending  Lender shall
be repaid as provided in Section 2.19.

                  (b) Each Lender shall  maintain in  accordance  with its usual
practice an account or accounts  evidencing the indebtedness of each Borrower to
such  Lender  resulting  from each Loan  made by such  Lender to such  Borrower,
including the amounts of principal and interest  payable and paid to such Lender
from time to time hereunder.

                  (c) The Administrative  Agent shall maintain accounts in which
it shall record (i) the amount of each Loan made  hereunder,  the Class and Type
thereof  and the  Interest  Period  applicable  thereto,  (ii) the amount of any
principal  or interest  due and  payable or to become due and payable  from each
Borrower to each Lender  hereunder  and (iii) the amount of any sum  received by
the  Administrative  Agent  hereunder  from a  Borrower  for the  account of the
Lenders and each Lender's share thereof.

                  (d) The entries  made in the accounts  maintained  pursuant to
paragraph  (b) or (c) of this  Section  shall be  prima  facie  evidence  of the
existence and amounts of the  obligations  recorded  therein;  provided that the
failure of any Lender or the  Administrative  Agent to maintain such accounts or
any error therein shall not in any manner affect the obligation of each Borrower
to repay the Loans in accordance with the terms of this Agreement.

                  (e) Any Lender may request  that Loans made by it be evidenced
by a promissory  note. In such event,  the  applicable  Borrower  shall prepare,
execute  and deliver to such Lender a  promissory  note  payable to the order of
such Lender (or, if requested by such Lender,  to such Lender and its registered
assigns) and in a form approved by the  Administrative  Agent.  Thereafter,  the
Loans evidenced by such promissory note and interest  thereon shall at all times
(including after assignment  pursuant to Section 10.04) be represented by one or
more  promissory  notes in such form  payable  to the  order of the payee  named
therein (or, if such promissory note is a registered note, to such payee and its
registered assigns).

                  (f) Any Loan made hereunder  shall be repaid by the applicable
Borrower or Borrowers in the currency that such Loan was originally  denominated
or deemed to be denominated;  provided,  however, that any Loan denominated in a
National Currency may be repaid in Euros in accordance with Section 1.05.

         SECTION  2.09.  Prepayment  of Loans.  (a) Any Borrower  shall have the
right at any time and from time to time to prepay any  Borrowing  in whole or in
part,  subject to prior notice in accordance with paragraph (b) of this Section;
provided that (i) each  prepayment of a Borrowing  shall be in an amount that is
an integral multiple of $1,000,000 and not less than $10,000,000,  and (ii) such
Borrower shall not have the right to prepay a Competitive Loan without the prior
consent of the Lender thereof.

                  (b) The applicable  Borrower  shall notify the  Administrative
Agent  by  telephone  (confirmed  immediately  by  telecopy)  of any  prepayment
hereunder (i) in the case of prepayment of a Eurodollar Revolving Borrowing, not
later than 11:00 a.m.,  New York City time,  three Business Days before the date
of  prepayment,  (ii) in the case of  prepayment of a Sterling  LIBOR  Revolving
Borrowing or a EURIBOR Revolving Borrowing,  not later than 11:00 a.m., New York
City time, four Business Days before the date of prepayment,(iii) in the case of
prepayment of a CD Borrowing, not later than 11:00 a.m., New York City time, two
Business Days before the date of  prepayment,  or (iv) in the case of prepayment
of an ABR Revolving  Borrowing,  not later than 11:00 a.m.,  New York City time,
one  Business  Day  before the date of  prepayment.  Each such  notice  shall be
irrevocable  and shall specify the prepayment  date and the principal  amount of
each Borrowing or portion  thereof to be prepaid;  provided that, if a notice of
prepayment is given in connection  with a conditional  notice of  termination of
the  Commitments as contemplated by Section 2.07, then such notice of prepayment
may be revoked if such  notice of  termination  is  revoked in  accordance  with
Section  2.07.  Promptly  following  receipt of any such  notice  relating  to a
Revolving  Borrowing,  the Administrative  Agent shall advise the Lenders of the
contents thereof. Each partial prepayment of any Revolving Borrowing shall be in
an amount  that would be  permitted  in the case of an  advance  of a  Revolving
Borrowing of the same Type as provided in Section  2.02.  Each  prepayment  of a
Revolving  Borrowing  shall be  applied  ratably  to the Loans  included  in the
prepaid  Borrowing.  Prepayments shall be accompanied by accrued interest to the
extent  required by Section 2.11.  Each  prepayment  shall include break funding
payments to the extent required by Section 2.14.

                  (c) In the event that (i) the  aggregate  principal  amount of
all Loans under this Agreement exceeds the total aggregate Lenders' Commitments;
(ii) the  aggregate  principal  amount of all Loans made to the  Company and the
Domestic  Subsidiary  Borrowers exceeds the Domestic  Available Amount; or (iii)
the  aggregate  principal  amount of all Loans  made to the  Foreign  Subsidiary
Borrowers  exceeds the Foreign  Available  Amount; in each case as determined by
the aggregate of all applicable  Dollar  Borrowings and the Dollar Equivalent of
all applicable  Alternate Currency  Borrowings on the first Business Day of each
month then, at the request of the  Administrative  Agent, the Company shall, and
shall cause each  Subsidiary  Borrower to,  prepay (A) in the case of clause (i)
above,  immediately,  and (B) in the case of clauses (ii) or (iii) above, within
three Business Days of such request,  an amount equal to the excess described in
clauses (i),  (ii), and (iii) above,  as  applicable,  or in the case of clauses
(ii) and (iii) above,  provide cash collateral by making a deposit in an account
with the Administrative  Agent, in the name of the Administrative  Agent and for
the benefit of the Lenders,  of an amount in cash and in the same currency so as
to equal  such  excess as of such  date plus any  accrued  and  unpaid  interest
thereon,  which cash  collateral  shall be  collaterally  assigned  as  security
pursuant to the Cash  Collateral  Account  Agreement,  which  agreement shall be
executed  and   delivered  by  the   Borrowers  to  the   Administrative   Agent
contemporaneously  with the payment of such cash  collateral;  provided that the
obligation to deposit such cash collateral shall become  effective  immediately,
and such deposit shall become  immediately  due and payable,  without  demand or
other  notice of any kind,  upon the  occurrence  of any Event of  Default  with
respect to any  Borrower  described in clause (h) or (i) of Article  VIII.  Such
deposit shall be held by the Administrative  Agent as collateral for the payment
and performance of the  obligations of the Borrowers  under this Agreement.  The
Administrative  Agent shall have exclusive  dominion and control,  including the
exclusive right of withdrawal, over such account. Other than any interest earned
on the  investment  of such  deposits,  which  investments  shall be made at the
option and sole  discretion of the  Administrative  Agent and at the  Borrowers'
risk and expense, such deposits shall not bear interest. Interest or profits, if
any,  on such  investments  shall  accumulate  in such  account.  Moneys in such
account shall be applied by the Administrative  Agent to satisfy  obligations of
the Borrowers  under this  Agreement.  If any Borrower is required to provide an
amount  of  cash  collateral  hereunder  as a  result  of  a  request  from  the
Administrative  Agent for a prepayment  under this Section,  such amount (to the
extent not applied as aforesaid) shall be returned to such Borrower within three
Business  Days after the earlier of (x) the first  Business  Day of a month that
the  Administrative  Agent  determines  that such cash  collateral  is no longer
required  pursuant to the terms of the first  sentence of this Section and (y) a
prepayment of the Loans in an amount equal to such cash collateral.
                  (d) If at any time the  Borrowers'  fail to satisfy any one or
more of the  conditions  precedent  set forth in Section 4.02 for any  Refunding
Borrowing,  the Company and each Subsidiary  Borrower shall prepay its Loans (i)
in the case of LIBOR Loans,  EURIBOR  Loans or CD Loans,  on the last day of the
Interest Period applicable thereto,  and (ii) in the case of Base Rate Loans, on
or before the  fifteenth  day  following the day on which notice is given by the
Company or the Administrative Agent of the failure to satisfy any such condition
precedent.

                  SECTION  2.10.  Fees.  (a) The  Company  agrees  to pay to the
Administrative  Agent for the account of each Lender a facility fee, which shall
accrue at the  Applicable  Rate for  facility  fees on the  daily  amount of the
Commitment of such Lender  (whether  used or unused)  during the period from and
including the Closing Date to but  excluding  the date on which such  Commitment
terminates; provided that, if such Lender continues to have any Revolving Credit
Exposure after its Commitment terminates,  then such facility fee shall continue
to accrue on the daily amount of such Lender's  Revolving  Credit  Exposure from
and including the date on which its  Commitment  terminates to but excluding the
date on which such Lender ceases to have any Revolving Credit Exposure.  Accrued
facility  fees  shall be  payable  in  arrears  on the last day of March,  June,
September  and  December  of each year and on the date on which the  Commitments
terminate,  commencing  on the first such date to occur  after the date  hereof;
provided that any facility fees accruing after the date on which the Commitments
terminate shall be payable on demand. All facility fees shall be computed on the
basis of a year of 360 days and shall be payable  for the actual  number of days
elapsed (including the first day but excluding the last day).

                  (b) The Borrowers agree to pay to the Administrative Agent for
the  account  of each  Lender  a  utilization  fee  which  shall  accrue  at the
Applicable  Rate for  utilization  fees on the  daily  amount  of such  Lender's
Revolving Credit Exposure plus the aggregate principal amount of its Competitive
Loans during the time the sum of the total Revolving  Credit  Exposures plus the
aggregate  principal  amount  of all  outstanding  Competitive  Loans  equals or
exceeds 33% of the total Commitments.  Utilization fees shall be computed on the
basis of a year of 360 days and shall be  payable  in arrears on the last day of
March, June, September and December of each year. Each Subsidiary Borrower shall
be  severally  obligated  to pay its  portion  of such fees  with  regard to its
Borrowings hereunder.  Notwithstanding the foregoing, the Company agrees that it
will remain obligated for all such fees.

                  (c) The Company agrees to pay to the Administrative Agent, for
its own account,  such fees as are set forth in the Fee Letter, on the dates and
in the manner specified therein.

                  (d) All fees payable hereunder shall be paid on the dates due,
in immediately available funds, to the Administrative Agent, for its own account
or for  distribution,  in the case of facility fees and utilization fees, to the
Lenders.
Fees paid shall not be refundable under any circumstances.

         SECTION 2.11.  Interest.  (a) The Loans  comprising  each ABR Borrowing
shall bear  interest for each day such Loans are  outstanding  at the  Alternate
Base Rate for such day. Any change in the Alternate Base Rate due to a change in
the Royal Bank Prime Rate or the Federal Funds Effective Rate shall be effective
from and  including  the  effective  date of such change in the Royal Bank Prime
Rate or the Federal Funds Effective Rate, as applicable.

                  (b) The Loans comprising each CD Borrowing shall bear interest
at the  Adjusted CD Rate for the  Interest  Period in effect for such  Borrowing
plus the Applicable Rate for LIBOR Borrowings plus 0.125% per annum.

                  (c) The Loans comprising each LIBOR Revolving  Borrowing shall
bear interest at the Adjusted Eurodollar LIBO Rate or the Adjusted Sterling LIBO
Rate, as applicable,  for the Interest  Period in effect for such Borrowing plus
the Applicable Rate.

                  (d) The Loans  comprising  each  LIBOR  Competitive  Borrowing
shall  bear  interest  at the  Adjusted  Eurodollar  LIBO  Rate or the  Adjusted
Sterling LIBO Rate, as  applicable,  for the Interest  Period in effect for such
Borrowing plus (or minus, as applicable) the Margin applicable to such Loan.

                  (e) The Loans  comprising  each  EURIBOR  Revolving  Borrowing
shall bear  interest at Adjusted  EURIBOR for the Interest  Period in effect for
such Borrowing plus the Applicable Rate.

                  (f) The Loans  comprising each EURIBOR  Competitive  Borrowing
shall bear  interest at Adjusted  EURIBOR for the Interest  Period in effect for
such Borrowing  plus (or minus,  as  applicable)  the Margin  applicable to such
Loan.

                  (g) Each Fixed Rate Loan shall bear interest at the Fixed Rate
applicable to such Loan.

                  (h)  Notwithstanding  the  foregoing,  if any  principal of or
interest  on any  Loan or any fee or  other  amount  payable  by the  applicable
Borrower  hereunder  is not paid when due,  whether  at  stated  maturity,  upon
acceleration  or otherwise,  such overdue amount shall bear  interest,  after as
well as before judgment, at a rate per annum equal to 2% plus the rate otherwise
applicable to such Loan as provided in the preceding paragraphs of this Section.

                  (i) Accrued  interest on each Loan shall be payable in arrears
on each Interest Payment Date for such Loan and, in the case of Revolving Loans,
upon termination of the Commitments; provided that (i) interest accrued pursuant
to paragraph (h) of this Section  shall be payable on demand,  (ii) in the event
of any  repayment or  prepayment  of any Loan (other than a prepayment of an ABR
Revolving Loan prior to the end of the Availability Period), accrued interest on
the  principal  amount  repaid or  prepaid  shall be payable on the date of such
repayment or prepayment and (iii) in the event of any conversion of any EURIBOR,
CD or LIBOR  Revolving  Loan  prior to the end of the  current  Interest  Period
therefor,  accrued  interest on such Loan shall be payable on the effective date
of such conversion.

                  (j) All interest hereunder shall be computed on the basis of a
year of 360 days,  except that interest on ABR Loans  calculated by reference to
the Royal Bank Prime Rate shall be  computed  on the basis of a year of 365 days
(or 366 days in a leap  year),  and in each case shall be payable for the actual
number of days elapsed (including the first day but excluding the last day). The
applicable  interest  rates shall be determined by the  Administrative  Agent in
accordance with the terms of this  Agreement,  and such  determination  shall be
conclusive absent manifest error.

                  (k) All interest  accruing on any Loan hereunder shall be paid
in the currency in which such Loan is denominated  or deemed to be  denominated;
provided,  however,  that the  interest  accruing on any Loan  denominated  in a
National Currency may be paid in Euros in accordance with Section 1.05.

         SECTION  2.12. Alternate Rate of Interest. If prior to the commencement
of any  Interest  Period for a CD  Borrowing,  a EURIBOR Borrowing  or  a  LIBOR
Borrowing:

                  (a) the Administrative Agent:

                  (i) determines (which determination shall be conclusive absent
         manifest  error) that  adequate and  reasonable  means do not exist for
         ascertaining  the Adjusted CD Rate, the Adjusted  Eurodollar LIBO Rate,
         the Adjusted Sterling LIBO Rate or Adjusted EURIBOR, as applicable, for
         such Interest Period; or

                  (ii) is advised by the Required  Lenders (or, in the case of a
         EURIBOR  Competitive Loan or a LIBOR  Competitive Loan, the Lender that
         is required to make such Loan) that the Adjusted CD Rate,  the Adjusted
         Eurodollar  LIBO Rate,  the  Adjusted  Sterling  LIBO Rate or  Adjusted
         EURIBOR,  as applicable,  for such Interest  Period will not adequately
         and fairly  reflect  the cost to such  Lenders (or Lender) of making or
         maintaining  their Loans (or its Loan)  included in such  Borrowing for
         such Interest Period;

then the  Administrative  Agent shall give notice  thereof to the  Company,  the
applicable  Borrower  and the  Lenders by  telephone  or telecopy as promptly as
practicable thereafter and, until the Administrative Agent notifies the Company,
the applicable  Borrower and the Lenders that the  circumstances  giving rise to
such notice no longer exist, (A) any Interest Election Request that requests the
conversion  of any  Revolving  Borrowing  to, or  continuation  of any Revolving
Borrowing as, a CD Borrowing,  a EURIBOR  Borrowing,  or a LIBOR  Borrowing,  as
applicable,  shall be ineffective,  (B) if any Borrowing  Request  requests a CD
Borrowing or a LIBOR Revolving Borrowing, as applicable, if such Borrowing is to
be denominated in Dollars, it shall be made as an ABR Borrowing, (C) any request
by the Company for a EURIBOR or LIBOR Competitive Borrowing shall be ineffective
and (D) any request for a EURIBOR or LIBOR Borrowing denominated in an Alternate
Currency shall be  ineffective;  provided that (I) if the  circumstances  giving
rise to such notice do not affect all the Lenders,  then requests by the Company
for EURIBOR or LIBOR Competitive  Borrowings may be made to Lenders that are not
affected thereby and (II) if the circumstances giving rise to such notice do not
affect  all  such  Types  of  Borrowings,  then the  other  unaffected  Types of
Borrowings shall be permitted.

                  (b) If, in relation to any Borrowing or proposed  Borrowing to
be denominated in an Alternate Currency, and with respect to any Interest Period
relative thereto:

                  (i) the Administrative Agent shall have received  notification
         from a  Lender  or  Lenders  whose  participations  in  such  Borrowing
         constitute at least 50% by value of such  Borrowing,  that by reason of
         circumstances  affecting the London  interbank  market or the Euro-zone
         interbank market, as applicable:

                           (A) deposits in the applicable Alternate Currency for
         the same period as such Interest  Period will not be readily  available
         to them in the  London  interbank  market  or the  Euro-zone  interbank
         market, as applicable,  in sufficient amounts in the ordinary course of
         business  to fund their  respective  Loans in such  Borrowing  for such
         Interest Period; or

                           (B) while such deposits are so available, the cost of
         such deposits exceeds the applicable LIBO Rate or EURIBOR as determined
         in relation to such Borrowing for such Interest Period; or

                  (ii) the Administrative Agent shall have received notification
         from any Lender (an "Affected  Lender") that by reason of any change in
         or  the  introduction  (or  re-introduction)  of or any  change  in the
         interpretation,  administration  or  application  of applicable  law or
         regulation  (in each such case after the date hereof or, if later,  the
         date on which the Affected  Lender became a part to this  Agreement) it
         is  unable  to fund its Loan in such  Borrowing  during  such  Interest
         Period by deposit(s) in the applicable  Alternate  Currency obtained in
         the London  interbank  market or the  Euro-zone  interbank  market,  as
         applicable, in the ordinary course of business;

         the  Administrative  Agent shall  promptly give written  notice of such
         determination or notification to the Company and each of the Lenders.

                  (c) After the giving of any notice by the Administrative Agent
pursuant to Section  2.12(b) to the effect that it has received  notification in
accordance with Section 2.12(b)(i)(A) or 2.12(b)(ii),  no Lender or, as the case
may be, no Affected  Lender shall be obliged to  participate in the Borrowing to
which  such   notification   relates  unless  such  Borrowing  is  already  then
outstanding.  The giving of any notice by the  Administrative  Agent pursuant to
Section 2.12(b)(i)(B) shall not relieve any Lender of any obligation it may have
under this  Agreement to make a Loan  (including  any Loan for which a Borrowing
Request was given prior to such notice by the Administrative Agent).

                  (d)  During  the  period of 15 days  after  the  giving of any
notice  by  the   Administrative   Agent  pursuant  to  Section   2.12(b),   the
Administrative  Agent (in consultation  with the Lenders or the Affected Lender)
shall  negotiate  with the  Company in good  faith  with a view to  ascertaining
whether a substitute  basis (a "Substitute  Basis") may be agreed for the making
of further  Borrowings and/or the maintaining of any existing  Borrowings by the
Lenders or such Affected Lender (as the case may be) to which such notice by the
Administrative  Agent  related for the Interest  Period(s)  applicable  to those
Borrowings.  If a  Substitute  Basis  is  agreed  by all the  Lenders  or by the
Affected  Lender  (as the  case  may  be) and the  Company  it  shall  apply  in
accordance  with its terms from the  commencement of such Interest  Period.  The
Administrative  Agent shall not agree to any  Substitute  Basis on behalf of any
Lender or Affected  Lender  without the prior consent of that Lender or Affected
Lender (as the case may be).

                  (e) If a Substitute  Basis is not so agreed by the Company and
all the Lenders or the  Affected  Lender (as the case may be) by the end of such
15 day period, each Lender's or Affected Lender's then existing Loan or Loans to
which the notice by the Administrative  Agent related shall bear interest during
the current Interest Period relative thereto at the rate which is the sum of (a)
the per annum rate certified by such Lender or Affected Lender to be its cost of
funds (from such sources as it may  reasonably  select out of those sources then
available  to it) for  such  Interest  Period  in  relation  to  such  Borrowing
multiplied by the Reserve Rate, plus (b) the Associated Costs Rate, plus (c) the
Applicable Rate.

                  (f) So long as any  Substitute  Basis is in  force or  Section
2.12(e) shall apply in relation to any Borrowing,  the Administrative  Agent, in
consultation  with the Company and each  Lender  (or,  if  applicable,  Affected
Lender) shall from time to time, but not less often then monthly, review whether
or not the  circumstances  referred to in Section  2.12(b)  still prevail with a
view to returning to the normal interest provisions of this Agreement.

         SECTION 2.13.  Illegality;  Increased  Costs.  (a) If any Change in Law
shall make it unlawful or  impossible  for any Lender to make,  maintain or fund
its  Loans,  such  Lender  shall  so  notify  the   Administrative   Agent,  the
Administrative  Agent shall immediately give notice thereof to the other Lenders
and to the  Company,  whereupon  until such Lender  notifies the Company and the
Administrative  Agent that the  circumstances  giving rise to such suspension no
longer  exist,  the  obligation  of such  Lender  to make  such  Loans  shall be
suspended.  If such Lender shall determine that it may not lawfully  continue to
maintain and fund any of its outstanding  Loans to maturity and shall so specify
in such notice,  the applicable  Borrower shall  immediately  prepay in full the
then  outstanding  principal  amount  of such  Loan  together  with the  accrued
interest thereon.

                  (b) If any  Change  in  Law,  including,  without  limitation,
reserve  requirements  imposed  by the  European  System of  Central  Banks with
respect  to the Euro or the  National  Currencies  on or after  January 1, 1999,
shall:

                  (i) impose,  modify or deem  applicable  any reserve,  special
         deposit or similar  requirement against assets of, deposits with or for
         the  account  of, or credit  extended  by, any Lender  (except any such
         reserve  requirement  reflected in the  Adjusted CD Rate,  the Adjusted
         Eurodollar  LIBO Rate,  the  Adjusted  Sterling  LIBO Rate or  Adjusted
         EURIBOR); or

                  (ii) impose on any Lender,  the London interbank market or the
         Euro-zone interbank market any other condition affecting this Agreement
         or any Loans made by such Lender;

and the result of any of the  foregoing  shall be to  increase  the cost to such
Lender of making or maintaining  any Loan (or of  maintaining  its obligation to
make any such  Loan) or to  increase  the cost to such  Lender or to reduce  the
amount of any sum received or  receivable by such Lender  hereunder  (whether of
principal, interest or otherwise), then the applicable Borrower will pay to such
Lender such additional amount or amounts as will compensate such Lender for such
additional costs incurred or reduction suffered.

                  (c) If any Lender  determines that any Change in Law regarding
capital requirements has or would have the effect of reducing the rate of return
on such Lender's capital or on the capital of such Lender's holding company,  if
any, as a  consequence  of this  Agreement or the Loans made by such Lender to a
level below that which such Lender or such Lender's  holding  company could have
achieved but for such Change in Law (taking  into  consideration  such  Lender's
policies  and the  policies of such  Lender's  holding  company  with respect to
capital  adequacy),  then from time to time the applicable  Borrower will pay to
such Lender such additional  amount or amounts as will compensate such Lender or
such Lender's holding company for any such reduction suffered.

                  (d) A  certificate  of a Lender  setting  forth the  amount or
amounts necessary to compensate such Lender or its holding company,  as the case
may be, as specified in paragraph  (b) or (c) of this Section shall be delivered
to the applicable  Borrower and shall be conclusive  absent manifest error.  The
applicable  Borrower  shall pay such Lender the amount  shown as due on any such
certificate within 10 days after receipt thereof.

                  (e)  Failure  or  delay on the part of any  Lender  to  demand
compensation  pursuant to this  Section  shall not  constitute  a waiver of such
Lender's  right to  demand  such  compensation;  provided  that  the  applicable
Borrower  shall not be required to compensate a Lender  pursuant to this Section
for any increased  costs or reductions  incurred more than 270 days prior to the
date that such  Lender  notifies  the  applicable  Borrower of the Change in Law
giving rise to such increased costs or reductions and of such Lender's intention
to claim  compensation  therefor;  provided  further  that, if the Change in Law
giving rise to such  increased  costs or  reductions  is  retroactive,  then the
270-day  period  referred  to above  shall be  extended to include the period of
retroactive effect thereof.

                  (f) Notwithstanding the foregoing  provisions of this Section,
a Lender  shall not be entitled  to  compensation  pursuant  to this  Section in
respect  of any  Competitive  Loan if the  Change  in Law that  would  otherwise
entitle it to such  compensation  shall have been  publicly  announced  prior to
submission of the Competitive Bid pursuant to which such Loan was made.

         SECTION 2.14. Break Funding  Payments.  In the event of (a) the payment
of any principal of any CD Loan,  EURIBOR  Loan,  LIBOR Loan, or Fixed Rate Loan
other than on the last day of an Interest Period applicable  thereto  (including
as a result of an Event of Default),  (b) the conversion of any CD Loan, EURIBOR
Loan or LIBOR Loan other than on the last day of the Interest Period  applicable
thereto,  (c) the failure to borrow,  convert,  continue or prepay any Revolving
Loan on the date specified in any notice delivered  pursuant hereto  (regardless
of whether such notice may be revoked  under  Section  2.09(b) and is revoked in
accordance  therewith),  (d) the  failure to borrow any  Competitive  Loan after
accepting the Competitive Bid to make such Loan, or (e) the assignment of any CD
Loan,  EURIBOR Loan, LIBOR Loan or Fixed Rate Loan other than on the last day of
the Interest Period  applicable  thereto as a result of a request by the Company
pursuant to Section 2.17, then, in any such event, the applicable Borrower shall
compensate  each  Lender for the loss,  cost and  expense  attributable  to such
event. In the case of a CD Loan,  EURIBOR Loan or LIBOR Loan, such loss, cost or
expense to any Lender  shall be deemed to include an amount  determined  by such
Lender to be the excess,  if any, of (i) the amount of interest which would have
accrued on the principal amount of such Loan had such event not occurred, at the
Adjusted CD Rate (in the case of a CD Loan),  Adjusted EURIBOR (in the case of a
EURIBOR Loan) or the Adjusted Eurodollar LIBO Rate or the Adjusted Sterling LIBO
Rate,  as  applicable,  (in the case of a LIBOR  Loan),  that  would  have  been
applicable to such Loan,  for the period from the date of such event to the last
day of the then current  Interest  Period therefor (or, in the case of a failure
to borrow, convert or continue, for the period that would have been the Interest
Period for such Loan),  over (ii) the amount of interest  which would  accrue on
such  principal  amount for such period at the  interest  rate which such Lender
would  bid  were it to bid,  at the  commencement  of such  period,  for  Dollar
deposits of a  comparable  amount and period from other banks in the  eurodollar
market.  A  certificate  of any Lender  setting forth any amount or amounts that
such Lender is entitled to receive  pursuant to this Section  shall be delivered
to the applicable  Borrower and shall be conclusive  absent manifest error.  The
applicable  Borrower  shall pay such Lender the amount  shown as due on any such
certificate within 10 days after receipt thereof.

         SECTION 2.15.  Taxes.  (a) Any and all payments by or on account of any
obligation of any Borrower hereunder shall be made free and clear of and without
deduction  for any  Indemnified  Taxes  or  Other  Taxes;  provided  that if any
Borrower shall be required to deduct any  Indemnified  Taxes or Other Taxes from
such payments,  then (i) the sum payable shall be increased as necessary so that
after  making  all  required  deductions  (including  deductions  applicable  to
additional sums payable under this Section) the Administrative Agent or a Lender
(as the case may be) receives an amount equal to the sum it would have  received
had no such deductions  been made, (ii) the applicable  Borrower shall make such
deductions and (iii) the applicable  Borrower shall pay the full amount deducted
to the relevant Governmental Authority in accordance with applicable law.

                  (b) In addition,  each  Borrower  shall pay any Other Taxes to
the relevant Governmental Authority in accordance with applicable law.

                  (c) Each Borrower shall indemnify the Administrative Agent and
each Lender,  within 10 days after written demand therefor,  for the full amount
of any Indemnified Taxes or Other Taxes paid by the Administrative Agent or such
Lender,  as the case may be, on or with  respect to any payment by or on account
of any obligation of such Borrower  hereunder  (including  Indemnified  Taxes or
Other Taxes imposed or asserted on or attributable to amounts payable under this
Section) and any penalties,  interest and reasonable  expenses arising therefrom
or with respect thereto,  whether or not such  Indemnified  Taxes or Other Taxes
were  correctly  or legally  imposed or  asserted by the  relevant  Governmental
Authority. A certificate as to the amount of such payment or liability delivered
to the applicable Borrower by a Lender or by the Administrative Agent on its own
behalf or on behalf of a Lender, shall be conclusive absent manifest error.

                  (d) As soon as  practicable  after any payment of  Indemnified
Taxes or Other Taxes by a Borrower to a Governmental  Authority,  the applicable
Borrower shall deliver to the  Administrative  Agent the original or a certified
copy of a receipt issued by such Governmental Authority evidencing such payment,
a copy of the return  reporting  such payment or other  evidence of such payment
reasonably satisfactory to the Administrative Agent.

                  (e) As of the date on which any Lender becomes a party hereto,
such Lender  confirms  that with respect to its Loans to a United  States person
(within  the  meaning of Section  7701(a)(30)  of the Code),  it is either (i) a
corporation  organized  under the laws of the  United  States of  America or any
state thereof, entitled to complete exemption from United States withholding tax
imposed on or with respect to any  payments,  including  fees,  to be made to it
pursuant to this Agreement,  or (ii) entitled to complete  exemption from United
States withholding tax on interest imposed on or with respect to any payments of
interest to be made pursuant to this Agreement (A) under an applicable provision
of a U.S.  Double  Taxation  Treaty,  (B) because it is acting through a branch,
agency or office in the United  States of America and any payment to be received
by it hereunder is effectively  connected with a trade or business in the United
States of America, or (C) because it is a recipient of portfolio interest within
the meaning of Section  871(h) or 881(c) of the Code.  Such  Lender,  as of such
date,  also  confirms  that with  respect  to its Loans  (or  interest  or other
payments relating thereto)  regarding which the U.K. Tax Act could reasonably be
expected to result in withholding tax  requirements  under the U.K. Tax Act (but
for the applicable Lender qualifying for the immediately  following  exemptions)
it is either (x) a bank as defined in Section 840A of the U.K.  Tax Act,  which,
for the  purposes  of  Sections  349 and 212 of the U.K.  Tax Act, is within the
charge  to  United  Kingdom  corporation  tax as  regards,  and is  beneficially
entitled to, any interest  received by it under this Agreement,  except that, if
that Section is repealed,  modified,  extended or re-enacted, the Administrative
Agent  may at any time and from  time to time  (acting  reasonably)  amend  this
definition  to reflect  such  repeal,  modification,  extension  or enactment by
giving notice of the amended definition to the Company, or (y) a person carrying
on a bona fide banking  business who is resident (as such term is defined in the
appropriate  U.K.  Double  Taxation  Treaty) in a country  with which the United
Kingdom has an appropriate  U.K. Double Taxation Treaty giving residents of that
country full  exemption  from United  Kingdom  taxation on interest and does not
carry on business in the United Kingdom through a permanent  establishment  with
which the indebtedness  under this Agreement in respect of which the interest is
paid is effectively  connected.  Each Lender that is not a corporation organized
under the laws of the  United  States of  America  or any  state  thereof  shall
provide to the Company and the Administrative Agent on or before the date of any
payment  by any  Borrower  hereunder,  or on the  date  of its  delivery  of the
Assignment  and  Acceptance  pursuant to which it becomes a Lender,  and at such
other  times  as  required  by  United  States  law  or as  the  Company  or the
Administrative  Agent  shall  reasonably  request,  two  accurate  and  complete
original  signed  copies of either (A)  Internal  Revenue  Service Form 4224 (or
successor form)  certifying that all payments to be made to it hereunder will be
effectively  connected  to a United  States  trade or  business  (the "Form 4224
Certification"),  or (B) Internal  Revenue Service Form 1001 (or successor form)
certifying  that it is entitled to the benefit of a provision  of a U.S.  Double
Taxation Treaty which completely  exempts from United States withholding tax all
payments of interest to be made to it hereunder (the "Form 1001 Certification").
In  addition,  each  Lender  agrees  that if it  previously  filed  a Form  4224
Certification it will deliver to the Company and the Administrative  Agent a new
Form 4224 Certification prior to the first payment date occurring in each of its
subsequent  taxable  years (or such other date as may be required in  compliance
with applicable law); and if it previously filed a Form 1001  Certification,  it
will  deliver to the Company and the  Administrative  Agent a new  certification
prior to the first payment date falling in the third year following the previous
filing  of  such  certification  (or  such  other  date  as may be  required  in
compliance with applicable law).

Each Lender also agrees to deliver to the Company and the  Administrative  Agent
such  other or  supplemental  forms as may at any time be  required  in order to
confirm or maintain in effect its entitlement to exemption from United States or
United  Kingdom  withholding  tax on any payments  hereunder,  provided that the
circumstances  of the Lender at the relevant time and applicable  laws permit it
to do so. Except as provided  immediately  below, if a Lender is organized under
the laws of a  jurisdiction  outside the United  States of  America,  unless the
Company and the Administrative  Agent have received a Form 1001 Certification or
Form 4224  Certification,  reasonably  satisfactory  to them indicating that all
payments of  interest,  to be made to such Lender  hereunder  are not subject to
United States  withholding  tax, the Company shall be entitled to withhold taxes
from  such  payments  at the  applicable  statutory  rate,  provided  that  such
withholding  shall not  increase  the amount of payments for the account of such
Lender to be made by the Company  pursuant to  Subsection  2.15(a).  If a Lender
determines,  as a result of any change in either (i) applicable law,  regulation
or treaty,  or in any official  application  thereof or (ii) its  circumstances,
that it is unable to submit  any form or  certificate  that it is  obligated  to
submit  pursuant to this  Section,  or that it is required to withdraw or cancel
any such form or certificate previously submitted,  it shall promptly notify the
Company  and the  Administrative  Agent of such  fact and the  Company  shall be
entitled to withhold taxes from such payments at the applicable  statutory rate,
it being understood that such withholding  shall increase the amount of payments
for the  account of such  Lender to be made by the  Company  pursuant to Section
2.15(a).  Each Lender  agrees to  indemnify  and hold the  Administrative  Agent
harmless from any United States or United Kingdom taxes, penalties, interest and
other expenses, costs and losses incurred or payable by the Administrative Agent
(i) as a result of such Lender's  failure to submit any form or certificate that
it is  required to provide  pursuant to this  Section or (ii) as a result of the
Administrative  Agent's  reliance  on any such form or  certificate  which  such
Lender has  provided  to it  pursuant  to this  Section.  Each Person that shall
become a Lender or a  Participant  pursuant  to Section  10.04  shall,  upon the
effectiveness of the related transfer,  be required to provide all of the forms,
certifications and statements  required pursuant to this Section,  provided that
in the case of a Participant  the obligations of such  Participant  shall be the
same as if it were a Lender, except that such Participant shall furnish all such
required  forms,  certifications  and  statements  to the Lender  from which the
related  participation  shall have been  purchased and such Lender shall provide
such forms to the Company and the Administrative Agent.

         SECTION  2.16.  Payments  Generally;  Pro Rata  Treatment;  Sharing  of
Set-offs.  (a) Each Borrower  shall make each payment  required to be made by it
hereunder  (whether of  principal,  interest,  fees or of amounts  payable under
Section 2.13, 2.14 or 2.15, or otherwise)  prior to 12:00 noon, New York City or
London  time,  as  applicable,  on the date when due, in  immediately  available
funds, without set-off or counterclaim.  Any amounts received after such time on
any date may, in the discretion of the  Administrative  Agent, be deemed to have
been received on the next  succeeding  Business Day for purposes of  calculating
interest  thereon.  All such  payments  shall be made to the  applicable  Agency
Account  for the  account of the  Lenders,  except  that  payments  pursuant  to
Sections  2.13,  2.14,  2.15 and 10.03  shall be made  directly  to the  Persons
entitled thereto.  The  Administrative  Agent shall distribute any such payments
received by it for the account of any other Person to the appropriate  recipient
promptly  following receipt thereof.  If any payment hereunder shall be due on a
day that is not a Business  Day,  the date for payment  shall be extended to the
next succeeding Business Day, and, in the case of any payment accruing interest,
interest thereon shall be payable for the period of such extension. All payments
hereunder shall be made in Dollars, except that with respect to any Loan that is
denominated  in an Alternate  Currency,  all payments of principal  and interest
with respect to such Loan shall be made in the Alternate  Currency in which such
Loan  is  denominated;   provided,  however,  that  with  respect  to  any  Loan
denominated  in a National  Currency,  all payments with respect  thereto may be
made in Euros in accordance with Section 1.05.

                  (b) If at any time  insufficient  funds  are  received  by and
available  to the  Administrative  Agent to pay fully all amounts of  principal,
interest  and fees then due  hereunder,  such  funds  shall be  applied  towards
payment of  interest  and fees then due  hereunder,  ratably  among the  parties
entitled thereto in accordance with the amounts of interest and fees then due to
such parties.

                  (c) If any Lender shall, by exercising any right of set-off or
counterclaim  or  otherwise,  obtain  payment in respect of any  principal of or
interest  on any of its  Revolving  Loans  resulting  in such  Lender  receiving
payment of a greater  proportion of the aggregate  amount of its Revolving Loans
and accrued interest  thereon than the proportion  received by any other Lender,
then the Lender  receiving such greater  proportion  shall purchase (for cash at
face value) participations in the Revolving Loans of other Lenders to the extent
necessary  so that the  benefit  of all such  payments  shall be  shared  by the
Lenders  ratably in  accordance  with the  aggregate  amount of principal of and
accrued interest on their respective  Revolving Loans;  provided that (i) if any
such  participations  are purchased and all or any portion of the payment giving
rise  thereto is  recovered,  such  participations  shall be  rescinded  and the
purchase price restored to the extent of such recovery,  without  interest,  and
(ii) the  provisions  of this  paragraph  shall not be construed to apply to any
payment made by a Borrower  pursuant to and in accordance with the express terms
of this Agreement or any payment obtained by a Lender as  consideration  for the
assignment of or sale of a participation  in any of its Loans to any assignee or
participant, other than to a Borrower or any Subsidiary or Affiliate thereof (as
to which the provisions of this paragraph shall apply).  Each Borrower  consents
to the  foregoing  and  agrees,  to the  extent it may  effectively  do so under
applicable  law,  that any Lender  acquiring  a  participation  pursuant  to the
foregoing  arrangements may exercise against such Borrower rights of set-off and
counterclaim with respect to such  participation as fully as if such Lender were
a direct creditor of such Borrower in the amount of such participation.

                  (d) Unless the Administrative Agent shall have received notice
from  a  Borrower  prior  to  the  date  on  which  any  payment  is  due to the
Administrative Agent for the account of the Lenders hereunder that such Borrower
will not make  such  payment,  the  Administrative  Agent  may  assume  that the
applicable  Borrower has made such payment on such date in  accordance  herewith
and may, in reliance upon such assumption,  distribute to the Lenders the amount
due.  In such  event,  if the  applicable  Borrower  has not in fact  made  such
payment,   then  each  of  the  Lenders   severally   agrees  to  repay  to  the
Administrative  Agent  forthwith  on demand  the amount so  distributed  to such
Lender with  interest  thereon,  for each day from and  including  the date such
amount  is  distributed  to it to but  excluding  the  date  of  payment  to the
Administrative  Agent,  at the greater of the Federal Funds Effective Rate and a
rate determined by the Administrative  Agent in accordance with banking industry
rules on interbank compensation.

                  (e) If any Lender  shall fail to make any payment  required to
be made by it pursuant to 2.05(b) or 2.16(d), then the Administrative Agent may,
in its discretion  (notwithstanding  any contrary provision  hereof),  apply any
amounts thereafter received by the Administrative  Agent for the account of such
Lender to satisfy such Lender's  obligations  under such Sections until all such
unsatisfied obligations are fully paid.

         SECTION 2.17.  Mitigation  Obligations;  Replacement of Lenders. (a) If
any Lender  requests  compensation  under  Section  2.13,  or if any Borrower is
required  to pay  any  additional  amount  to  any  Lender  or any  Governmental
Authority  for the  account of any Lender  pursuant to Section  2.15,  then such
Lender shall use reasonable  efforts to designate a different lending office for
funding or booking its Loans  hereunder or to assign its rights and  obligations
hereunder to another of its offices, branches or Affiliates, if, in the judgment
of such Lender,  such  designation or assignment  (i) would  eliminate or reduce
amounts  payable  pursuant to Section  2.13 or 2.15,  as the case may be, in the
future  and (ii)  would not  subject  such  Lender to any  unreimbursed  cost or
expense and would not otherwise be disadvantageous to such Lender. Each Borrower
hereby agrees to pay all reasonable  costs and expenses  incurred by such Lender
in connection with any such designation or assignment.

                  (b) If any Lender requests compensation under Section 2.13, or
if any  Borrower is required to pay any  additional  amount to any Lender or any
Governmental  Authority for the account of any Lender  pursuant to Section 2.15,
or if any Lender  defaults in its obligation to fund Loans  hereunder,  then the
Company may, at its sole expense and effort,  upon notice to such Lender and the
Administrative  Agent,  require  such  Lender to assign  and  delegate,  without
recourse  (in  accordance  with and  subject to the  restrictions  contained  in
Section 10.04),  all its interests,  rights and obligations under this Agreement
(other than any  outstanding  Competitive  Loans held by it) to an assignee that
shall assume such obligations (which assignee may be another Lender, if a Lender
accepts such assignment);  provided that (i) the Company shall have received the
prior  written  consent of the  Administrative  Agent,  which  consent shall not
unreasonably  be withheld,  (ii) such Lender shall have  received  payment of an
amount equal to the outstanding  principal of its Loans (other than  Competitive
Loans), accrued interest thereon,  accrued fees and all other amounts payable to
it hereunder, from the assignee (to the extent of such outstanding principal and
accrued interest and fees) or the Company (in the case of all other amounts) and
(iii) in the case of any such assignment resulting from a claim for compensation
under  Section 2.13 or payments  required to be made  pursuant to Section  2.15,
such assignment will result in a reduction in such  compensation or payments.  A
Lender  shall not be required to make any such  assignment  and  delegation  if,
prior  thereto,  as a result  of a  waiver  by such  Lender  or  otherwise,  the
circumstances  entitling the Company to require such  assignment  and delegation
cease to apply.

         SECTION 2.18.  Foreign  Available Amount  Designation.  Once per Fiscal
Quarter,  the Company,  may, at its sole option,  designate or  redesignate  the
amount of the Foreign  Available  Amount by  delivering a written  notice to the
Administrative  Agent  not less than five  Business  Days  prior to the date the
Company proposes that the newly designated Foreign Available Amount would become
effective;  provided,  that no such designation of the Foreign  Available Amount
may occur if a Default  exists or if the sum of the Revolving  Credit  Exposures
plus the aggregate  principal amount of outstanding  Competitive  Loans, at such
time,  with respect to the Foreign  Subsidiary  Borrowers or the Company and the
Domestic Subsidiary Borrowers, as applicable, would, after giving effect to such
designation  and any  concurrent  payments  on such  Loans,  exceed the  Foreign
Available Amount or the Domestic Available Amount, respectively.

         SECTION 2.19. Extension of Stated Maturity Date. (a) No earlier than 90
days and no later than 60 days prior to an  Anniversary  Date,  the Company may,
subject to satisfaction of the conditions precedent for a Borrowing other than a
Refunding  Borrowing set forth in Section 4.02,  request in writing delivered to
the Administrative Agent an extension of the Maturity Date for a period equal to
one year from the then applicable Maturity Date (the "Extension  Request").  The
Maturity Date shall be extended as provided in this Section 2.19 if at least the
Required Lenders consent to such extension.  Each Lender shall, no later than 30
days after  receiving from the  Administrative  Agent the  applicable  Extension
Request,  notify the Company  and the  Administrative  Agent of its  election to
extend or not extend the Maturity Date as requested in such  Extension  Request.
If the Required  Lenders  shall approve in writing the extension of the Maturity
Date requested in such Extension Request,  the Maturity Date shall automatically
and  without  any  further  action by any  Person  be  extended  for the  period
specified in such Extension  Request;  provided that (i) each extension pursuant
to this Section 2.19 shall be for a maximum of one year, and (ii) the Commitment
of any Lender  that does not consent in writing  within 30 days after  receiving
from the Administrative Agent the applicable Extension Request (a "Non-Extending
Lender")  shall,  unless earlier  terminated in accordance  with this Agreement,
expire on the  Maturity  Date in effect  on the date of such  Extension  Request
(such Maturity Date, if any,  referred to as the  "Commitment  Expiration  Date"
with respect to such Non-Extending  Lender).  If, within 30 days after receiving
from the Administrative  Agent the applicable  Extension  Request,  the Required
Lenders  shall not  approve  in  writing  the  extension  of the  Maturity  Date
requested  in an  Extension  Request,  the  Maturity  Date shall not be extended
pursuant to such  Extension  Request.  The  Administrative  Agent shall promptly
notify (y) the Lenders and the Company of any  extension  of the  Maturity  Date
pursuant to this  Section 2.19 and (z) the Company and the Lenders of any Lender
which becomes a Non-Extending Lender.

                  (b) Loans owing to any Non-Extending  Lender on the Commitment
Expiration Date with respect to such Lender shall be repaid in full on or before
the Commitment Expiration Date.

                  (c) Each Borrower shall have the right, so long as no Event of
Default  has  occurred  and  is  then  continuing,  upon  giving  notice  to the
Administrative Agent and the Non-Extending  Lenders, to prepay in full the Loans
made to it owing to the  Non-Extending  Lenders,  together with accrued interest
thereon,  any amounts payable  pursuant to Sections 2.11,  2.13,  2.14, 2.15 and
10.03(b) and any accrued and unpaid facility fee or other amounts payable to the
Non-Extending Lenders hereunder and/or, upon giving not less than three Business
Days'  notice to the  Non-Extending  Lenders and the  Administrative  Agent,  to
cancel the whole or part of the Commitments of the Non-Extending Lenders.

                  (d)  Notwithstanding  the  foregoing,  if any Lender becomes a
Non-Extending  Lender,  the  Company  may,  at its own  expense  and in its sole
discretion and prior to the then stated  Maturity  Date,  require such Lender to
transfer or assign,  in whole or in part,  without  recourse (in accordance with
Section 10.04), all or part of its interests,  rights and obligations under this
Agreement  to an assignee  permitted  under  Section  10.04  (provided  that the
Company with the full cooperation of such Lender,  can identify such an assignee
that is ready,  willing and able to be an assignee with respect  thereto)  which
shall assume such assigned obligations (which assignee may be another Lender, if
such assignee Lender accepts such assignment); provided that (i) the assignee or
the Company,  as the case may be, shall have paid to such Lender in  immediately
available  funds  the  principal  of and  interest  accrued  to the date of such
payment  on the Loans  made by it  hereunder  and all other  amounts  owed to it
hereunder,  including, without limitation, any amounts owing pursuant to Section
10.03(b)  and any amounts  that would be owing under said  Section if such Loans
were prepaid on the date of such  assignment,  and (ii) such assignment does not
conflict with any applicable  law of any  Governmental  Authority.  Any assignee
which becomes a Lender as a result of such an  assignment  made pursuant to this
paragraph  (d) shall be deemed to have  consented  to the  applicable  Extension
Request and, therefore, shall not be a Non-Extending Lender.

         SECTION 2.20. Addition or Termination of Subsidiary Borrowers.  So long
as no Default  exists,  the Company may from time to time provide written notice
to the  Administrative  Agent, and the  Administrative  Agent shall  immediately
thereafter  provide a copy of such notice along with a copy of all documentation
relating thereto received from the Company to each of the Lenders:

                   (a)  Designating  any  of  its  wholly  owned,   directly  or
indirectly,  Subsidiaries  organized  under  the laws of the  United  States  of
America,  any State  thereof  or the  District  of  Columbia,  as an  additional
Domestic Subsidiary Borrower and shall execute and deliver,  and cause each such
newly designated  Domestic  Subsidiary  Borrower to execute and deliver,  to the
Administrative  Agent a Joinder Agreement  (together with all documents required
to be attached thereto)  whereupon such Subsidiary shall thereafter qualify as a
Domestic Subsidiary Borrower.

                   (b)  Designating  any  of  its  wholly  owned,   directly  or
indirectly,  Subsidiaries  organized under the laws of the United Kingdom or any
Participating   Member   State  and  located  in  the  United   Kingdom  or  any
Participating  Member State, as an additional  Foreign  Subsidiary  Borrower and
shall  execute  and  deliver,  and cause  each  such  newly  designated  Foreign
Subsidiary  Borrower  to execute  and  deliver,  to the  Administrative  Agent a
Joinder Agreement  (together with all documents required to be attached thereto)
whereupon  such  Subsidiary  shall  thereafter  qualify as a Foreign  Subsidiary
Borrower;  provided,  however,  that for purposes of this Section  2.20(b),  any
Subsidiary  of  the  Company  that  is  required  by the  applicable  law of its
jurisdiction  of  organization  or  formation  to be owned by a citizen  of such
jurisdiction or Person  organized or formed under the laws of such  jurisdiction
in an amount  equal to or less than one percent of the  capital  stock or equity
interest of such  Subsidiary  and such one percent or lesser amount of ownership
does not provide for voting or  distribution  rights in excess of such ownership
percentage or otherwise  give a Controlling  interest to such Person,  then, for
purposes of this Section  2.20(b),  such Subsidiary shall be deemed to be wholly
owned by the Company.

                  (c) With respect to any Subsidiary Borrower,  that the Company
is terminating such Subsidiary's  designation as a Domestic  Subsidiary Borrower
or a  Foreign  Subsidiary  Borrower,  as  the  case  may  be,  whereupon  if all
obligations  of such  Subsidiary  Borrower to the  Administrative  Agent and the
Lenders under or in connection with this Agreement have been  indefeasibly  paid
in full pursuant to the terms hereof, such Subsidiary shall thereafter no longer
be a Subsidiary Borrower hereunder.

         SECTION 2.21. Change in Control. If a Change in Control shall occur (i)
the Company will, ten days after the occurrence thereof, give each Lender notice
thereof and shall  describe  in  reasonable  detail the facts and  circumstances
giving  rise  thereto  and (ii) each  Lender  may,  at any time at its option by
notice to the  Borrowers  and the  Administrative  Agent given not later than 60
days  after  such  Change  in  Control,  (x)  terminate  its  Commitment,  which
Commitment shall thereupon be terminated,  and (y) by three Business Days notice
to the  Borrowers  and the  Administrative  Agent  declare  the Loans held by it
(together with accrued interest thereon) and any other amounts payable hereunder
for its  account to be, and such Loans and such other  amounts  shall  thereupon
become,  immediately due and payable without  presentment,  demand,  protest, or
other notice of any kind, all of which are hereby waived by the Borrowers.


                                   ARTICLE III

                         Representations and Warranties

         To induce  the  Lenders to enter  into this  Agreement  and to make the
Loans,  each  Borrower   represents  and  warrants  (such   representations  and
warranties  to  survive  any  investigation  and the making of the Loans) to the
Lenders and the Administrative Agent that:

         SECTION  3.01.   Corporate  Existence  and  Power.  The  Company  is  a
corporation duly  incorporated,  validly existing and in good standing under the
laws of the State of Delaware. Each Material Subsidiary organized under the laws
of the United States of America, any State thereof, or the District of Columbia,
is a corporation duly  incorporated,  validly existing and in good standing (or,
if such  Subsidiary  is a limited  liability  company,  is a  limited  liability
company duly formed,  validly  existing and in good standing)  under the laws of
its  jurisdiction of  incorporation,  organization  or formation.  Each Material
Subsidiary  organized under the laws of a jurisdiction  other than United States
of America,  any State  thereof,  or the  District of Columbia is a company duly
formed and validly existing under the laws of its jurisdiction of formation. The
Company and each  Material  Subsidiary  has all  requisite  corporate or limited
liability  company  power  and  all  material  governmental  licenses,  permits,
authorizations,  qualifications, consents and approvals required to carry on its
business as now conducted  which, if not obtained,  could reasonably be expected
to have a Material Adverse Effect.

         SECTION   3.02.   Corporate   and   Governmental   Authorization;    No
Contravention.  The execution, delivery and performance of this Agreement by the
Company and each Subsidiary  Borrower are within each such Borrower's  corporate
or limited liability company powers,  have been duly authorized by all necessary
corporate or limited liability company action,  require no approval of or filing
with any  governmental  body,  agency or  official or any other  Person,  do not
conflict  with,  contravene  or  constitute  a default  under any  provision  of
applicable law or regulation or of the  certificate of  incorporation,  by-laws,
articles of  association or memorandum of association of such Borrower or of any
agreement,  judgment, injunction, order, decree or other instrument binding upon
such Borrower  unless such conflict  could not  reasonably be expected to have a
Material  Adverse  Effect,  and will not result in the creation or imposition of
any mortgage,  security  interest or other lien or  encumbrance  on any asset or
revenues of such Borrower or any of its Subsidiaries.

         SECTION 3.03. Binding Effect. This Agreement constitutes a legal, valid
and  binding  agreement  of each of the  Company  and each  Subsidiary  Borrower
enforceable against each Borrower in accordance with its terms.

         SECTION 3.04.  Financial Information.

         (a) The consolidated  balance sheet of the Company and its Consolidated
Subsidiaries as of December 31, 1997, and the related consolidated statements of
income, retained earnings and cash flows for the year then ended, reported on by
Arthur Andersen L.L.P. and set forth in the Company's 1997 Annual Report, a copy
of  which  has  been  delivered  to  each of the  Lenders,  fairly  present,  in
conformity with GAAP, the consolidated financial position of the Company and its
Consolidated  Subsidiaries  as of such date and their  consolidated  results  of
operations and cash flows for such year.

         (b) the unaudited  consolidated statement of financial condition of the
Company and its Consolidated Subsidiaries at September 30, 1998, and the related
consolidated  statements  of income and retained  earnings and cash flows of the
Company and its  Consolidated  Subsidiaries for the nine months ending September
30, 1998, heretofore furnished to the Lenders present fairly, in conformity with
GAAP, the  consolidated  financial  condition of the Company at the date of said
statements for said periods,  subject to year-end audit  adjustments in the case
of such unaudited statements.

         (c) At the Effective Date, there has been no material adverse change in
the  business,  assets,  operations,   prospects  or  condition,   financial  or
otherwise,  of the Company and its Consolidated  Subsidiaries,  taken as a whole
since  September 30, 1998,  including with regard thereto the selected pro forma
financial  information  dated as of and for the nine months ended  September 30,
1998,  set forth in the  Company's  S-4 filed with the SEC, and  effective as of
January 27, 1999.

         SECTION 3.05. Litigation.  Except as may have been disclosed in writing
to the Lenders prior to the signing hereof, there is no material action, suit or
proceeding pending,  or to the knowledge of the Company  threatened,  against or
affecting  the Company or any  Subsidiary  before any court or arbitrator or any
governmental  body,  agency or official  which could  reasonably  be expected to
result in a Material Adverse Effect.

         SECTION 3.06.  Compliance with ERISA.

         (a) Neither the Company nor any ERISA Affiliate has failed to comply in
any material  respect with the  applicable  provisions of ERISA and the Code and
the regulations promulgated thereunder (including, without limitation,  sections
4068, 4069 and 4212 of ERISA),  where such failure could  reasonably be expected
to result in a Material Adverse Effect.

         (b)  Other  than  premiums  to the PBGC due in the  normal  course,  no
liability to the PBGC (with respect to which the Company or any ERISA  Affiliate
is delinquent)  has been incurred and remains  unsatisfied or is expected by the
Company to be  incurred  with  respect  to any Plan by the  Company or any ERISA
Affiliate  which could  reasonably  be expected to result in a Material  Adverse
Effect.

         (c)  Neither  the  Company  nor any ERISA  Affiliate  is  obligated  to
contribute  to, or has  incurred a  withdrawal  liability  with  respect to, any
Multiemployer  Plan in an amount that would be materially adverse to the Company
and its Subsidiaries taken as a whole.

         (d) Full  payment has been made of all amounts  that the Company or any
ERISA  Affiliate  is  required  under  the  terms of each  Plan to have  paid as
contributions  to such Plan as of the last day of the most recent fiscal year of
such Plan  ended  prior to the date  hereof  (or will be made  within the period
described in Section 404 of the Code) and no accumulated  funding deficiency (as
defined in Section  302 of ERISA and  Section  412 of the Code),  whether or not
waived, exists with respect to any Plan. Each Plan satisfies the minimum funding
standard of Section 412 of the Code.

         (e) The amount of Benefit Liabilities under each Plan, determined as of
the end of the  Company's  most  recently  ended  fiscal  year (on the  basis of
assumptions  prescribed  by the PBGC for  purposes of Section 4044 of ERISA) did
not exceed the current  value of the assets of such Plans  determined as of such
date in an amount that,  individually  or in the aggregate  with such amount for
all Plans, exceeds $25,000,000.

         SECTION 3.07.  Environmental  Matters. The Company and each Subsidiary,
and to the  best of the  Company's  knowledge,  any  former  subsidiary  and any
predecessor in interest of the Company or of any Subsidiary, and with respect to
all of the Property of the Company and its Subsidiaries, and each of the plants,
sites and  facilities  presently or formerly  owned,  operated,  controlled,  or
leased  by the  Company  or  any of its  Subsidiaries,  has  complied  with  all
applicable Environmental Laws during the period such Subsidiary,  plant, site or
facility was owned, operated,  controlled or leased by the Company or any of its
Subsidiaries, except in any such case, where such failure to so comply could not
reasonably be expected to have a Material  Adverse  Effect.  Neither the Company
nor any of its Subsidiaries has received any notice of, or has knowledge of, any
actual or threatened  claim,  legal  proceeding or  investigation  regarding the
Company or any of its Subsidiaries,  or any of the respective  plants,  sites or
facilities currently or formerly owned, operated, leased or controlled by any of
them,  related to Environmental Laws which alone or together with all other such
matters  known to the Company  could  reasonably  be expected to have a Material
Adverse Effect.

         SECTION 3.08.  Taxes. The Company and its  Subsidiaries  have filed all
United  States  Federal  income tax returns and all other  material  tax returns
which are  required to be filed by them and have paid all taxes due  pursuant to
such  returns or  pursuant  to any  assessment  received  by the  Company or any
Subsidiary,  except such taxes or assessments, if any, as are being contested in
good faith by appropriate proceedings. The charges, accruals and reserves on the
books of the  Company  and its  Subsidiaries  in respect  of taxes  are,  in the
opinion of the Company, adequate.

         SECTION  3.09.  Investment  Company  Act.  None of the  Borrowers is an
investment  company within the meaning of the Investment Company Act of 1940, as
amended,  or directly  or  indirectly  controlled  by or acting on behalf of any
Person which is an investment company, within the meaning of such Act.

         SECTION 3.10. Public Utility Holding Company Act. None of the Borrowers
is a "public utility company,  or an "affiliate," or a "subsidiary  company of a
"public  utility  company,"  or a  "holding  company,"  or an  "affiliate"  or a
"subsidiary  company" of a "holding  company" or of a "subsidiary  company" of a
"holding  company,"  as such terms are  defined in the  Public  Utility  Holding
Company Act of 1935, as amended.

         SECTION  3.11.  Use of Proceeds.  No portion of the Loans will be used,
directly or indirectly,  (a) to purchase or carry any Margin Stock, (b) to repay
or otherwise  refinance  indebtedness  of any  Borrower  incurred to purchase or
carry any Margin Stock, or (c) to extend credit for the purpose of purchasing or
carrying any Margin Stock.

         SECTION 3.12. Disclosure.  The Company has disclosed to the Lenders all
agreements,  instruments and corporate or other  restrictions to which it or any
of its Material  Subsidiaries  is subject,  and all other  matters  known to it,
that,  individually or in the aggregate,  could reasonably be expected to result
in a Material Adverse Effect. None of the other reports,  financial  statements,
certificates  or other  information  furnished by or on behalf of the Company or
its  Material  Subsidiaries  to  the  Administrative  Agent  or  any  Lender  in
connection  with the  negotiation of this  Agreement or delivered  hereunder (as
modified  or  supplemented  by other  information  so  furnished)  contains  any
material  misstatement  of fact or omits to state any material fact necessary to
make the statements  therein, in the light of the circumstances under which they
were made, not misleading;  provided that,  with respect to projected  financial
information, each Borrower represents only that such information was prepared in
good faith based upon assumptions believed to be reasonable at the time.

         SECTION  3.13.  Year 2000  Compliance.  The Company  believes  that any
reprogramming  required to permit the proper  functioning,  in and following the
year 2000, of (a) the Company's, or any Material Subsidiary's,  computer systems
and  (b)  equipment  containing  embedded  microchips   (including  systems  and
equipment  supplied  by others  or with  which the  Company's,  or any  Material
Subsidiary's,  systems  interface)  and the  testing  of all  such  systems  and
equipment,  as  so  reprogrammed,   to  the  extent  necessary  to  prevent  any
significant  disruptions  to the business and  operations of the Company and its
Subsidiaries on a consolidated  basis,  will be completed by September 30, 1999.
The cost to the Company and its Material  Subsidiaries of such reprogramming and
testing  and of the  reasonably  foreseeable  consequences  of year  2000 to the
Company (including, without limitation,  reprogramming errors and the failure of
others'  systems or  equipment)  will not result in a Default or other  event or
circumstance  that could  reasonably  be  expected  to have a  Material  Adverse
Effect.

         SECTION 3.14.  Material  Subsidiaries.  As of the Effective  Date,  the
Subsidiaries  of the Company  that qualify as Material  Subsidiaries  under this
Agreement and that are not Subsidiary Borrowers are those Subsidiaries listed on
Schedule 3.14 attached hereto.

                                   ARTICLE IV

                                   Conditions

signature  page of this  Agreement)  that such party has signed a counterpart of
this Agreement.

                  (b) The  Administrative  Agent shall have received a favorable

                  (c) The  Administrative  Agent shall have received a favorable
written opinion (addressed to the Administrative Agent and the Lenders and dated

substantially  in the form of Exhibit  B-2,  and  covering  such  other  matters
relating to the Borrowers,  this Agreement or the  Transactions  as the Required
Lenders shall reasonably request.  Each Borrower hereby requests such counsel to
deliver such opinion.

                  (d)  The   Administrative   Agent  shall  have  received  such
documents  and  certificates  as the  Administrative  Agent or its  counsel  may
reasonably request relating to the organization,  existence and good standing of
each  Borrower  organized  under the laws of the United  States of America,  any

the  United  States,  any  State  thereof,  or the  District  of  Columbia,  the
authorization of the Transactions,  and any other legal matters relating to such

satisfactory to the Administrative Agent and its counsel.

                  (e) The Administrative Agent shall have received a certificate
from each Borrower, dated the Effective Date and signed by the President, a Vice

compliance with the conditions set forth in paragraphs (a), (b), (c), and (d) of
Section 4.02.

                  (f) The  Administrative  Agent shall have received for its own
account,  or for the account of the Lenders, as the case may be, all fees, costs
and expenses due and payable pursuant to the Fee Letter and Section 10.03.

                  (g) All conditions  precedent  related to the Company's merger

                  (h) Each of the Oryx  Facility  and the ABN  Facility  A shall
have  been  terminated  and all  respective  obligations  thereunder  have  been
satisfied, subject only to funding of the initial Loans under this Agreement.

The  Administrative  Agent  shall  notify each  Borrower  and the Lenders of the
Effective Date, and such notice shall be conclusive and binding. Notwithstanding
the foregoing,  the obligations of the Lenders to make Loans hereunder shall not
become effective unless each of the foregoing conditions is satisfied (or waived
pursuant  to  Section  10.02) at or prior to 5:00 p.m.,  New York City time,  on
March 31,  1999  (and,  in the event such  conditions  are not so  satisfied  or
waived, the Commitments shall terminate at such time).

         SECTION 4.02.  Each Credit  Event.  The  obligation of  each  Lender to
make,  convert or continue a Loan on the occasion of any Borrowing is subject to
the satisfaction of the following conditions:

                  (a) On the  occasion of any  Borrowing  other than a Refunding
Borrowing, each of the representations and warranties of the Borrowers set forth
in this  Agreement  shall  be true  and  correct  on and as of the  date of such
Borrowing.   On  the  occasion  of  any   Refunding   Borrowing,   each  of  the
representations  and  warranties of the  Borrowers set forth in this  Agreement,
other than the  representations  and warranties  set forth in Sections  3.04(c),
3.05  and  3.07,  shall  be  true  and  correct  on and as of the  date  of such
Borrowing.

                  (b) At the time of and immediately after giving effect to such
Borrowing, no Default shall have occurred and be continuing.

                  (c) At the time of and immediately after giving effect to such

Borrowing,  at any time when the  Applicable  Rate is determined by reference to
Level Three,  Four,  Five or Six as provided in the Pricing  Schedule,  the Debt
Leverage Ratio is equal to or less than 3.5:1.00.

                  (e) The  Administrative  Agent  shall have  received a Joinder
Agreement (together with all documents required to be attached thereto) executed
and delivered by the Company and each Subsidiary  Borrower that is designated as
such by the Company  subsequent to the Effective  Date,  and the  Administrative
Agent shall have  delivered a copy of such Joinder  Agreement  (together  with a
copy of all documents required to be attached thereto) to each of the Lenders.

Each Borrowing  shall be deemed to constitute a  representation  and warranty by
each Borrower on the date thereof as to the matters specified in paragraphs (a),
(b), (c) and (d) of this Section.


                                    ARTICLE V

                              Affirmative Covenants

                  Until the Commitments  have expired or been terminated and the
principal of and interest on each Loan and all fees payable hereunder shall have
been paid in full,  each Borrower  covenants and agrees with the Lenders that it
will:

         SECTION 5.01.  Information.  Deliver, or cause to  be delivered, to the
Administrative Agent and each Lender:

         (a) to the extent not already  delivered  pursuant to another clause of
this Section  5.01,  as soon as available and in any event within 120 days after
the end of each fiscal year of the Company,  (i) a consolidated balance sheet of
the Company and its Consolidated  Subsidiaries as of the end of such fiscal year
and the related  consolidated  statements of income,  retained earnings and cash
flows for such fiscal year, setting in each case in comparative form the figures

independent public accountants of nationally  recognized  standing,  and (ii) an
audited   consolidated  balance  sheet  of  each  Subsidiary  Borrower  and  its
Consolidated  Subsidiaries  as of the end of such  fiscal  year and the  related
consolidated profit and loss account and statements of retained earnings of such
fiscal year,  setting forth in each case in comparative form the figures for the
previous  fiscal year,  accompanied by (A) the report thereon of Arthur Andersen
L.L.P.  or other  independent  public  accounts  of  internationally  recognized
standing,  or (B) if such financial  statements are not otherwise reported on by
independent public  accountants,  a certificate of the Financial Officer of such
Subsidiary Borrower as to fairness of presentation, GAAP and consistency;

         (b) to the extent not already  delivered  pursuant to another clause of
this  Section  5.01,  (i) as soon as  available  and in any event within 60 days

Company,  (A) a consolidated  balance sheet of the Company and its  Consolidated
Subsidiaries  as of the  end of  such  quarter,  (B)  the  related  consolidated

request of any Lender, may reasonably request.

         SECTION  5.02.   Payment  of  Taxes.   Pay,  will  cause  each  of  its
Subsidiaries  to pay, all material  taxes,  assessments  and other  governmental
charges  imposed upon it or any of its Properties or assets or in respect of any
of its  franchises,  business,  income or profits before any penalty or interest
accrues thereon, and all material claims (including,  without limitation, claims
for labor, services,  materials and supplies) for sums which have become due and
payable and which by law have or might become a Lien upon any of its  Properties
or assets,  non-payment of which could reasonably be expected to have a Material
Adverse Effect,  provided that no such tax, assessment,  charge or claim need be
paid if being  contested  in good  faith  by  appropriate  proceedings  promptly
initiated  and  diligently  conducted  so long as no Lien  has  attached  to any
Property of the Company or its Subsidiaries as a result thereof.

         SECTION 5.03.  Insurance.  Maintain,  or cause to be  maintained,  with
financially  sound  and  reputable  insurers,  insurance  with  respect  to  its
Properties  and business  and the  Properties  and business of its  Subsidiaries
against loss or damage of the kinds  customarily  insured against by corporation
of established  reputation engaged in the same or similar business and similarly
situated,  of such types and in such amounts as are  customarily  carried  under
similar  circumstances by such other corporations;  provided,  however,  that in
lieu of any such  insurance,  any Borrower or any such Subsidiary may maintain a
system or systems of self-insurance  which are in accord with sound practices of
similarly  situated  corporations  of established  reputation  maintaining  such
systems  and with  respect  to which  such  Borrower  or such  Subsidiary  shall
maintain adequate  insurance  reserves in accordance with GAAP and in accordance
with sound actuarial and insurance principles.

         SECTION 5.04. Conduct of Business and Maintenance of Existence.  Except
as permitted by Section 6.03,  at all times  preserve and keep in full force and
effect,  and cause each  Material  Subsidiary to preserve and keep in full force
and effect,  its  existence,  and rights and franchises  deemed  material to the
Properties,  business, prospects, profits, condition (financial or otherwise) or
operations  of the Company and its  Subsidiaries  taken as a whole,  except that
such rights and franchises and the existence of any Material  Subsidiary  (other
than those of a Subsidiary  Borrower)  may be  terminated  if, in the good faith
judgment of the Board of Directors of the Company,  such  termination  is in the
best interest of the Company and is not disadvantageous to the Lenders.

         SECTION 5.05. Compliance with Laws. Comply, and use its best efforts to
cause each of its  Subsidiaries to comply,  with all applicable  laws, rules and
regulations and orders of any Governmental Authority,  non-compliance with which

         SECTION 5.06.  Compliance with Environmental  Laws. Comply, and use its
best efforts to cause each of its  Subsidiaries  and each of its Affiliates that
are controlled by it or its  Subsidiaries to comply,  in a timely fashion,  with
the  provisions of all  Environmental  Laws,  failure with which to comply could
reasonably be expected to have a Material  Adverse Effect.  Each Borrower agrees
to defend,  indemnify  and hold the  Administrative  Agent and each Lender,  and
their   respective   directors,    officers,   and   employees   ("Environmental
Indemnitees")  harmless from any loss, liability,  cost, damage, fines, response
costs,  investigative  and monitoring costs,  abatement costs,  attorneys' fees,
experts' or  consultants'  fees,  claims or expenses or any other  Environmental
Liabilities ("Costs") which any such person may incur or suffer as a result of a
breach by the Company or any Subsidiary Borrower of the preceding covenants,  or
as the result of the  breach of any  representation  or  warranty  contained  in
Section 3.07 or as a result of any Environmental Liability,  legal proceeding or
investigation regarding the Company or any of its Subsidiaries,  or any of their
respective plants,  sites or facilities  currently or formerly owned,  operated,
leased or controlled by any of them,  related to Environmental  Laws;  provided,
however,  that with respect to plants,  sites,  or  facilities  formerly  owned,
operated,  leased or controlled by the Company or any of its  Subsidiaries,  the
indemnification  obligations  hereunder  shall relate only to Costs  incurred or
suffered  as a  result  of  an  Environmental  Liability,  legal  proceeding  or
investigation  relating to the ownership,  operation,  lease,  or control by the
Company or any of its  Subsidiaries  of such plants,  sites or  facilities or in
relation  to any plant,  site or facility  jointly  owned,  operated,  leased or
controlled with any other Person, to Costs incurred by virtue of this Agreement.
In no  event  shall  any  Environmental  Indemnitee  be  required  to  make  any
expenditure  or bring any cause of action to enforce the  Company's  obligations
and  liability  under  and  pursuant  to this  Section.  THE  COMPANY  AND  EACH
SUBSIDIARY  BORROWER  SHALL  INDEMNIFY THE RESPECTIVE  ENVIRONMENTAL  INDEMNITEE
REGARDLESS  OF WHETHER THE ACT,  OMISSION,  FACTS,  CIRCUMSTANCES  OR CONDITIONS
GIVING  RISE TO SUCH  INDEMNIFICATION  WERE  CAUSED  IN  WHOLE OR IN PART BY THE
RESPECTIVE  ENVIRONMENTAL  INDEMNITEE'S  SIMPLE (BUT NOT GROSS) NEGLIGENCE.  The
indemnifications  set out in this Section shall survive the  termination of this
Agreement and shall continue to be the personal  liability and obligation of the
Company and each Subsidiary  Borrower,  binding upon them. The  indemnifications
set forth in this Section are also subject to the provisions of Section 10.03(b)
of this  Agreement,  except to the extent  such  provisions  conflict  with this
Section in which case the provisions of this Section shall control.

         SECTION 5.07. Use of Proceeds. Use the proceeds of the Loans made under
this Agreement for working  capital and general  corporate  purposes,  including
non-contested acquisitions,  refinancing of obligations under the ABN Facility A
and the Oryx  Facility,  and  commercial  paper  back-up in the United States of
America and the European Union.  No portion of the Loans will be used,  directly
or  indirectly,  (a) to  purchase  or carry any  Margin  Stock,  (b) to repay or
otherwise  refinance  indebtedness of any Borrower incurred to purchase or carry
any Margin  Stock,  or (c) to extend  credit for the  purpose of  purchasing  or
carrying any Margin Stock.

         SECTION 5.08.  Notice   of   Changed   Credit   Rating.     Notify  the
Administrative Agent promptly on becoming aware of any change or proposed change
in any Rating.

         SECTION 5.09.  Subsidiary  Borrowers.  In the case of the Company,   at
all times own, directly or indirectly,  all  outstanding  capital  stock  of the
Subsidiary Borrowers free and clear of all liens or encumbrances.

         SECTION 5.10. Year 2000  Compliance.  Perform,  and, in the case of the
Company,  cause each Material Subsidiary to perform, any reprogramming  required
to permit  the  proper  functioning,  in and  following  the year  2000,  of its
computer systems and equipment containing embedded microchips (including systems
and  equipment  supplied  by others or with  which its  systems  interface)  and
perform the testing of all such systems and equipment,  as so  reprogrammed,  to
the extent necessary to prevent any significant  disruptions to the business and
operations of the Company and its  Subsidiaries on a consolidated  basis,  which
testing shall be completed by September 30, 1999.

                                   ARTICLE VI

                               Negative Covenants

         Until the  Commitments  have expired or terminated and the principal of
and interest on each Loan and all fees payable hereunder have been paid in full:

         SECTION 6.01. Compliance with ERISA. The Company will not, and will not
permit any of its  Subsidiaries  to, (i) engage in any transaction in connection
with which the Company or any of its  Subsidiaries  could be subject to either a
civil penalty  assessed  pursuant to Section  502(i) of ERISA,  a tax imposed by
Section 4975 of the Code, or a lien pursuant to Section 412(n) of the Code, (ii)
terminate  any Plan in a manner,  or take any other  action with  respect to any
such Plan (including,  without limitation, a substantial cessation of operations
within the  meaning of Section  4068(f)  of ERISA),  which  could  result in any
liability of the Company or any of its  Subsidiaries to the PBGC or to a trustee
appointed pursuant to Section 4042(b) or (c) of ERISA, or incur any liability to
the PBGC on account of a  termination  of a Plan  under  Section  4064 of ERISA,
(iii)  fail to make  full  payment  when due of all  amounts  which,  under  the
provisions of any Plan or Section  412(m) of the Code, the Company or any of its
Subsidiaries  is  required  to pay as  contributions  thereto,  (iv)  incur  any
complete or partial withdrawal liability under Title IV of ERISA with respect to
any  Multiemployer  Plan,  or  (v)  permit  to  exist  any  accumulated  funding
deficiency,  whether  or not  waived,  with  respect  to any  Plan,  if,  in the
aggregate,  such penalty or tax or such  liability,  or the failure to make such
payment,  or the  existence  of such  deficiency,  as the case  may be,  exceeds
$25,000,000.

         SECTION 6.02.  Limitation  on Secured  Debt.  Neither the Company nor a
Subsidiary  Borrower  will,  and the Company will not,  permit any  Consolidated
Subsidiary to create, incur, assume or suffer to exist, any Indebtedness secured
by a Lien on any Restricted  Property or any  Indebtedness of the Company or any
Subsidiary,   without  effectively  providing  that  the  Loans  and  any  other
Indebtedness  evidenced by this Agreement  shall be secured  equally and ratably
with  (or  prior  to)  such  secured  Indebtedness,  so  long  as  such  secured
Indebtedness  shall be so secured,  unless,  after giving  effect  thereto,  the
aggregate  principal  amount of all such  secured  Indebtedness  (not  including
secured  Indebtedness  permitted to be secured  under  clauses (a) to (j) below)
plus the  aggregate  "value"  (as  defined  below) of all  "sale  and  leaseback
transaction"  (as  defined  below,  but not  including  any  sale  or  leaseback
transaction  the  proceeds  of which  have  been or will be  applied  to  funded
Indebtedness of the Company or its Subsidiaries within 120 days from the time of
such transaction) would not exceed five percent (5%) of Stockholders'  Equity of
the Company;  provided,  however, that this Section 6.02 shall not apply to, and
there  shall be  excluded  from  secured  Indebtedness  in any  computation  for
purposes of this Section 6.02, any Indebtedness secured by:

                  (a)      Liens existing on the date of this Agreement;

                  (b) any Lien existing on any asset of any  corporation  at the
time such  corporation  becomes a  Consolidated  Subsidiary  and not  created in
contemplation of such event and which does not extend to any other assets of the
Company or any Consolidated Subsidiary;

                  (c) any Lien on any asset  securing  Indebtedness  incurred or
assumed for the purpose of financing  all or any part of the cost of  acquiring,
constructing  or improving such asset,  provided that such Lien attaches to such
asset  concurrently with or within 24 months after the acquisition or completion
of  construction  or  improvement   thereof,   and  provided  further  that  the
Indebtedness  secured  by such Lien  shall  not  exceed  the cost of  acquiring,
constructing or improving such asset;

                  (d) any Lien on any asset of any  corporation  existing at the
time such  corporation is merged or  consolidated  with or into the Company or a
Consolidated Subsidiary and not created in contemplation of such event and which
does  not  extend  to any  other  assets  of  the  Company  or any  Consolidated
Subsidiary;

                  (e) any Lien  existing on any asset  prior to the  acquisition
thereof  by  the  Company  or a  Consolidated  Subsidiary  and  not  created  in
contemplation of such acquisition;

                  (f) any Lien  arising  pursuant  to any  order of  attachment,
distraint or similar legal process arising in connection with court  proceedings
so long as the execution or other enforcement  thereof is effectively stayed and
the claims  secured  thereby are being  contested  in good faith by  appropriate
proceedings;

                  (g) Liens to secure  indebtedness of the pollution  control or
industrial  revenue  bond  type and Liens in favor of the  United  States or any
State  thereof,  or  any  department,  agency,  instrumentality,   or  political
subdivision of any such  jurisdiction,  to secure any indebtedness  incurred for
the  purpose  of  financing  all or any  part of the  purchase  price or cost of
constructing or improving the property subject thereto;

                  (h)  any  Lien  (including  Liens  in  respect  of  production
payments)  to secure the payment of all or any part of the cost of  exploration,
drilling,  mining,  or  development of property which had prior to September 30,
1998,  produced no material volumes of hydrocarbons,  minerals,  timber or other
products or by-products produced or extracted from such property,  provided that
the  Indebtedness  secured by such Lien shall not exceed the cost of  exploring,
drilling,  mining or development  such property;  and provided further that such
Lien shall not extend to any property  other than the property  being  explored,
drilled, mined or developed;

                  (i) Liens securing Indebtedness incurred by the Company or any
of its Subsidiaries to pay all or any part of the cost of exploration,  drilling
or development  any North Sea properties  within the  territorial  waters of the
United Kingdom,  provided, that the Indebtedness secured by such Liens shall not
exceed the cost of such  exploration,  drilling,  or  development;  and provided
further that such Lien shall not extend to any property  other than the property
being explored, drilled or developed; and

                  (j)  any  Lien  arising  out  of the  refinancing,  extension,
renewal or refunding of any Indebtedness secured by any Lien permitted by any of
the  foregoing  clauses  of this  section,  provided  that  the  amount  of such
Indebtedness is not increased and is not secured by any additional assets;

         For  purposes  of this  Section  6.02,  the term  "sale  and  leaseback
transaction"  means any arrangement  with any bank,  insurance  company or other
lender or investor or to which any such lender or investor is a party, providing
for the leasing by the  Company or any of its  Consolidated  Subsidiaries  for a
period,  including renewals, in excess of three years on any Restricted Property
owned or leased by the Company or any of its Consolidated Subsidiaries which has
been  sold  or  transferred,   more  than  120  days  after  the  completion  of
construction and commencement of full operation  thereof,  by the Company or any
of its Consolidated  Subsidiaries to such lender or investor or to any Person to
whom funds have been or are to be  advanced  by such  lender or  investor on the
security of such  Restricted  Property.  For purposes of this Section 6.02,  the
term Avalue@ means, with respect to a sale and leaseback transaction,  as of any
particular  time, an amount equal to the greater of (i) the net proceeds of sale
of  the  Restricted   Property  leased  pursuant  to  such  sale  and  leaseback
transaction,  and (ii) the fair value of such Restricted Property at the time of
entering into such sale and leaseback  transaction as determined by the Board of
Directors of the  Company,  in each case  multiplied  by a fraction of which the
numerator  is the  number  of full  years  remaining  in the  term of the  lease
(without  regard to renewal  options) and the  denominator is the number of full
years of the full term of the lease (without regard to renewal options).

         SECTION 6.03.  Consolidations, Mergers and Sales of Assets.

         (a) Neither the Company nor any Subsidiary  Borrower will be a party to
any  merger  or  consolidation  or sell,  lease  or  otherwise  transfer  all or
substantially  all of its  Property;  provided  that the  Company  may  merge or
consolidate with another  corporation and may sell, lease or otherwise  transfer
all or substantially  all of its Property as an entirety to another  corporation
if (i) the surviving or acquiring corporation (if other than the Company) (A) is
organized under the laws of the United States or a jurisdiction  thereof and (B)
expressly assumes by writing reasonably satisfactory to the Required Lenders the
covenants and obligations in this Agreement,  and (ii) immediately  after giving
effect  to such  transaction,  (x) no  condition  or  event  shall  exist  which
constitutes a Default, (y) the Consolidated Tangible Net Worth shall not be less
than $1,000,000,000, and (z) in the event that any Rating or any expected Rating
(resulting  from  such  merger,  consolidation,  sale,  lease or  transfer)  for
determining the Applicable Rate is determined by reference to Level Three, Four,
Five or Six as provided in the Pricing  Schedule,  the Debt Leverage Ratio shall
be equal to or less than 3.5:1.00;  and provided,  further,  that any Subsidiary
Borrower may merge or consolidate  with another  corporation and may sell, lease
or otherwise transfer all or substantially all of its Property as an entirety to
another corporation if (i) the surviving or acquiring corporation (if other than
another  Subsidiary  Borrower)  (A) is  organized  under the laws of the country
under whose laws such  Subsidiary  Borrower is  organized  and (B)  executes and
delivers to the Administrative  Agent a Joinder Agreement,  (ii) all outstanding
capital stock of the surviving or acquiring  corporation is owned by the Company
free and clear of any Lien,  and (iii)  immediately  after giving effect to such
transaction,  no condition or event shall exist which  constitutes a Default and
the conditions for a Borrowing other than a Refunding  Borrowing as set forth in
Section 4.02  (whether or not a Borrowing  occurs in connection  therewith)  are
satisfied.

         (b) Concurrently with the public disclosure thereof,  the Company shall
give written notice to the  Administrative  Agent and the Lenders  describing in
reasonable detail any proposed  transaction  described in this Section, the date
on which it is proposed to be consummated  and the identity and  jurisdiction of
organization of the proposed successor or transferee corporation.

         (c)  Notwithstanding  anything contained in this Section 6.03, the Oryx
Merger is hereby expressly permitted.

         SECTION 6.04. Transactions with Affiliates. Neither the Company nor any
Subsidiary  Borrower will engage,  directly or  indirectly,  in any  transaction
(including,  without limitation, the purchase, sale or exchange of assets or the
rendering of any service) with any Affiliate,  except in the ordinary  course of
and pursuant to the reasonable  requirements of the Company's or such Subsidiary
Borrower's or such Affiliate's  business and upon fair and reasonable terms that
are  substantially  the same as those which might be obtained in an arm's length
transaction  at the time from  Persons  which are not such an  Affiliate or upon
terms which could not reasonably be expected to have a Material  Adverse Effect;
provided,  however,  that  taxes  may be  allocated  among the  Company  and its
Affiliates  in any  manner  consistent  with  Section  1552  (or  any  successor
provision)  of the Code,  general and  administrative  expenses may be allocated
among the Company and its Affiliates in any manner  consistent  with Section 482
(or any  successor  provision)  of the Code,  and  interest  may be  charged  or

                                   ARTICLE VII

                                    Guaranty

         SECTION  7.01.  The  Guaranty.  In order to induce the Lenders to enter
into this  Agreement and to extend credit  hereunder and in  recognition  of the
direct  benefits to be received  by the Company  from the  proceeds of the Loans
made to the  Subsidiary  Borrowers,  the  Company  hereby,  unconditionally  and
irrevocably  guarantees as primary obligor and not merely as surety the full and
prompt payment when due, whether upon maturity, by acceleration or otherwise, of

Administrative Agent or the Lenders. If any or all of the Guaranteed Obligations
of the Subsidiary  Borrowers to the Administrative  Agent or the Lenders becomes
due and  payable  hereunder,  the Company  unconditionally  promises to pay such
indebtedness  to the  Administrative  Agent for the  account  of each  Lender on
demand, in the applicable currency of such Guaranteed Obligation,  together with
any and all  reasonable  expenses  which may be incurred  by the  Administrative
Agent or the  Lenders in  collecting  any of the  Guaranteed  Obligations.  This
Guaranty is a guaranty  of payment  and not  collection.  All  payments  made by
Company under this  Guaranty  shall be made on the same basis as payments by the
Company under Sections 2.08 and 2.09.

         SECTION 7.02. Bankruptcy. Additionally, the Company unconditionally and
irrevocably  guarantees the payment of any and all of the Guaranteed Obligations
of the Subsidiary  Borrowers to the Administrative Agent and the Lenders whether
or not then due or payable by such  Subsidiary  Borrowers upon the occurrence in
respect of any  Subsidiary  Borrower of any of the events  specified in Sections
8(h)  or  8(i),  and  unconditionally  and  irrevocably  promises  to  pay  such
Guaranteed  Obligations  to the  Administrative  Agent for the  account  of each
Lender on demand, in the applicable currency of such Guaranteed Obligation.

         SECTION  7.03.  Nature of  Liability.  (a) The liability of the Company
hereunder is exclusive and  independent of any security for or other guaranty of
the Guaranteed  Obligations of the Subsidiary  Borrowers whether executed by the
Company,  any other  guarantor or by any other party,  and the  liability of the
Company  hereunder  shall not be affected or impaired by (i) any direction as to
application of payment by any Subsidiary Borrower or by any other party, or (ii)
any other  continuing or other guaranty,  undertaking or maximum  liability of a
guarantor  or of  any  other  party  as to  the  Guaranteed  Obligations  of the
Subsidiary Borrowers,  or (iii) any payment on or in reduction of any such other
guaranty or  undertaking,  or (iv) any  dissolution,  termination  or  increase,
decrease or change in personnel by the Subsidiary Borrowers,  or (v) any payment
made to the  Administrative  Agent or the Lenders on the Guaranteed  Obligations
which the Administrative  Agent or the Lenders repay to the Subsidiary Borrowers
pursuant  to  court  order  in  any  bankruptcy,  reorganization,   arrangement,
moratorium or other debtor relief  proceeding,  and the Company waives any right
to the deferral or modification  of its  obligations  hereunder by reason of any
such proceeding.

                  (b) If claim is ever made upon the Administrative Agent or any
Lender for repayment or recovery of any amount or amounts received in payment or
on account of any of the Guaranteed  Obligations and any of the aforesaid payees
repays all or part of said amount by reason of (i) any judgment, decree or order
of any court or administrative  body having  jurisdiction over such payee or any
of its property or (ii) any  settlement or compromise of any such claim effected
by such payee with any such claimant (including any Subsidiary  Borrower),  then
and in such event the Company  agrees  that any such  judgment,  decree,  order,
settlement or compromise shall be binding upon the Company,  notwithstanding any
revocation hereof or other instrument evidencing any liability of any Subsidiary
Borrower,  and the Company shall be and remain  liable to the  aforesaid  payees
hereunder  for the amount so repaid or  recovered  to the same extent as if such
amount had never originally been received by any such payee.

         SECTION 7.04.  Independent  Obligation.  The obligations of the Company
hereunder  are  independent  of the  obligations  of any other  guarantor or the
Subsidiary  Borrowers,  and a  separate  action or actions  may be  brought  and
prosecuted  against  the  Company  whether or not action is brought  against any
other  guarantor  or the  Subsidiary  Borrowers  and  whether  or not any  other
guarantor or the  Subsidiary  Borrowers be joined in any such action or actions.
The Company waives,  to the fullest extent  permitted by law, the benefit of any
statute of  limitations  affecting  its liability  hereunder or the  enforcement
thereof.  Any payment by any  Subsidiary  Borrower or other  circumstance  which
operates to toll any statute of limitations as to such Subsidiary Borrower shall
operate to toll the statute of limitations as to the Company. This Guaranty is a
continuing one with respect to the Guaranteed  Obligations,  and all liabilities
to which it applies or may apply under the terms  hereof  shall be  conclusively
presumed to have been created in reliance hereon.

         SECTION 7.05. Authorization.  The Company authorizes the Administrative
Agent and the Lenders  without  notice or demand (except as shall be required by
applicable statute and cannot be waived), and without affecting or impairing its
liability under this Article VII, from time to time to:

                  (a) change the manner,  place or terms of payment  of,  and/or
change or extend the time of payment of, renew,  increase,  accelerate or alter,
any of the  Guaranteed  Obligations  (including  any increase or decrease in the
rate of interest  thereon),  any security  therefor,  or any liability  incurred
directly or indirectly in respect  thereof,  and the Guaranty  herein made shall
apply to the Guaranteed Obligations as so changed, extended, renewed or altered;

                  (b) take and hold  security for the payment of the  Guaranteed
Obligations and sell, exchange,  release,  surrender,  realize upon or otherwise
deal with in any manner and in any order any property by  whomsoever at any time
pledged  or  mortgaged  to  secure,  or  howsoever   securing,   the  Guaranteed
Obligations  or any  liabilities  (including  any of those  hereunder)  incurred
directly  or  indirectly  in  respect  thereof  or  hereof,  and/or  any  offset
thereagainst;

                  (c)  exercise  or refrain from  exercising any rights  against
the Subsidiary  Borrowers or others or otherwise act or refrain from acting;

                  (d)  release   or   substitute  any  one  or  more  endorsers,
guarantors, the Subsidiary Borrowers or other obligors;

                  (e) settle or compromise  any of the  Guaranteed  Obligations,
any  security  therefor  or any  liability  (including  any of those  hereunder)
incurred  directly  or  indirectly  in  respect  thereof  or  hereof,   and  may
subordinate  the  payment  of all or any  part  thereof  to the  payment  of any
liability  (whether due or not) of the Subsidiary  Borrowers to their  creditors
other than the Lenders;

                  (f) apply any sums by whomsoever paid or howsoever realized to
any  liability  or  liabilities  of the  Subsidiary  Borrowers  to  the  Lenders
regardless of what liability or liabilities of the Subsidiary  Borrowers  remain
unpaid;

                  (g) consent to or waive any breach of, or any act, omission or
default under,  this Agreement or any of the instruments or agreements  referred
to herein,  or otherwise  amend,  modify or supplement  this Agreement or any of
such other instruments or agreements; and/or

                  (h)  take  any  other  action  which  would,  under  otherwise
applicable principles of common law, give rise to a legal or equitable discharge
of the Company from its liabilities under this Guaranty.

         SECTION 7.06. Subordination.  Any of the Indebtedness of the Subsidiary
Borrowers now or hereafter owing to the Guarantor is hereby  subordinated to the
Guaranteed  Obligations of the Subsidiary  Borrowers owing to the Administrative
Agent and the  Lenders;  and if the  Administrative  Agent so requests at a time
when an  Event  of  Default  exists,  all such  Indebtedness  of the  Subsidiary
Borrowers  to the  Company  shall be  collected,  enforced  and  received by the
Company for the  benefit of the  Lenders and be paid over to the  Administrative
Agent on behalf of the Lenders on account of the  Guaranteed  Obligations of the
Subsidiary  Borrowers to the Lenders,  but without affecting or impairing in any
manner the liability of the Company under the other provisions of this Guaranty.

         SECTION 7.07. Waiver. (a) The Company waives any right (except as shall
be  required  by  applicable  statute  and  cannot be  waived)  to  require  the
Administrative  Agent or the  Lenders  to (i)  proceed  against  any  Subsidiary
Borrower,  any other  guarantor  or any other  party,  (ii)  proceed  against or
exhaust any security held from the Subsidiary Borrowers,  any other guarantor or
any other party or (iii) pursue any other remedy in the  Administrative  Agent's
or the Lenders'  power  whatsoever.  The Company  waives any defense based on or
arising out of any defense of the Subsidiary  Borrowers,  any other guarantor or
any other party, other than payment in full of the Guaranteed Obligations, based
on or  arising  out of the  disability  of any  Subsidiary  Borrower,  any other
guarantor  or any  other  party,  or  the  unenforceability  of  the  Guaranteed
Obligations or any part thereof from any cause,  or the cessation from any cause
of the liability of the Subsidiary  Borrowers  other than payment in full of the
Guaranteed  Obligations.  The Administrative Agent and the Lenders may, at their
election,  foreclose on any  security  held by the  Administrative  Agent or the
Lenders  by one or more  judicial  or  nonjudicial  sales,  whether or not every
aspect of any such sale is  commercially  reasonable (to the extent such sale is
permitted  by  applicable  law),  or  exercise  any other  right or  remedy  the
Administrative  Agent and the Lenders may have against the Subsidiary  Borrowers
or any other party, or any security,  without  affecting or impairing in any way
the  liability  of the  Company  hereunder  except to the extent the  Guaranteed
Obligations  have been paid. The Company  waives any defense  arising out of any
such  election by the  Administrative  Agent and the  Lenders,  even though such
election  operates  to  impair  or  extinguish  any  right of  reimbursement  or
subrogation  or other  right or remedy of the  Company  against  any  Subsidiary
Borrower or any other party or any security.

                  (b)  The  Company   waives  all   presentments,   demands  for
performance,  protests  and notices,  including  without  limitation  notices of
nonperformance, notices of protest, notice of acceleration, notices of intent to
accelerate,  notices of dishonor,  notices of acceptance of this  Guaranty,  and
notices of the existence,  creation or incurring of new or additional Guaranteed
Obligations. The Company assumes all responsibility for being and keeping itself
informed of the Subsidiary Borrowers' financial condition and assets, and of all
other  circumstances  bearing  upon the  risk of  nonpayment  of the  Guaranteed
Obligations  and the  nature,  scope and extent of the risks  which the  Company
assumes and incurs hereunder,  and agrees that the Administrative  Agent and the
Lenders  shall have no duty to advise the Company of  information  known to them
regarding such circumstances or risks.

         SECTION 7.08.  Legal  Limitations  of  Liability.  It is the desire and
intent  of the  Company,  the  Administrative  Agent and the  Lenders  that this
Guaranty shall be enforced against the Company to the fullest extent permissible
under  the  laws and  public  policies  applied  in each  jurisdiction  in which
enforcement is sought.  If, however,  and to the extent that, the obligations of
the  Company  under  this  Guaranty  shall  be  adjudicated  to  be  invalid  or
unenforceable  for any reason  (including,  without  limitation,  because of any
applicable   state  or  federal  law  relating  to  fraudulent   conveyances  or
transfers),  then the amount of the Guaranteed  Obligations of the Company shall
be deemed to be reduced  and the  Company  shall pay the  maximum  amount of the
Guaranteed Obligations which would be permissible under applicable law.

         SECTION 7.09.  Discharge Only Upon Payment.  The Company's  obligations
hereunder  shall  remain in full force and  effect  until the  Commitments  have
terminated  and the  principal  and interest on the Loans and all other  amounts
payable by the Borrowers  under this Agreement shall have been paid in full. The
provisions of this Section 7.09 shall survive the  termination of this Agreement
and any  satisfaction or discharge of any Subsidiary  Borrower or the Company by
virtue of any payment, any court order or any applicable law. The obligations of
the Company under this Article VII constitute  the full recourse  obligations of
the Company enforceable against it to the full extent of all its Property.

         SECTION 7.10.  Subrogation.  The Company irrevocably waives any and all
rights to which it may be  entitled,  by  operation  of law or  otherwise,  upon
making any payment hereunder to be subrogated to the rights of the payee against
any  Subsidiary  Borrower  with  respect  to such  payment  or  otherwise  to be
reimbursed,  indemnified  or  exonerated by any  Subsidiary  Borrower in respect
thereof in any  bankruptcy,  insolvency  or  similar  proceeding  involving  any
Subsidiary Borrower as debtor commencing within one year after the making of any
payment by any  Subsidiary  Borrower  under this  Agreement or in respect of the
Loans.  The Company hereby  further waives any right to enforce via  subrogation
any other  remedy  which the  Administrative  Agent or any Lender now has or may
hereafter  have  against any  Subsidiary  Borrower  and any right of  indemnity,
reimbursement  or contribution  against any Subsidiary  Borrower the Company may
have by virtue of the Company's  performance of its obligations  hereunder until
such time as the  Administrative  Agent and the Lenders  have been  indefeasibly
paid in full and the Commitments have expired or been terminated.


                                  ARTICLE VIII

                                Events of Default

         If any of the following events ("Events of Default") shall occur:

days  after  written  notice  thereof  has  been  given  to the  Company  by the
Administrative Agent at the request of any Lender;

         (d) any  Borrower  shall fail to observe or  perform  any  covenant  or
agreement  contained in this Agreement (other than those covered by clauses (a),

         (e) any  representation,  warranty,  certification or statement made or
deemed,  pursuant to the terms hereof, to have been made by any Borrower in this

respect when made or deemed to have been made.

         (f) the  Company  or any of its  Subsidiaries  shall  fail to make  any
payment in respect of any Material Financial  Obligations when due or within any
applicable grace period; or

         (g)  any  event  or  condition  occurs  that  results  in any  Material
Financial  Obligation  becoming  due  prior to its  scheduled  maturity  or that
enables or permits  (with or without the giving of notice,  the lapse of time or
both) the holder or holders of any Material Financial  Obligation or any trustee
or agent on its or their behalf to cause any Material  Financial  Obligation  to
become due, or to require the prepayment,  repurchase,  redemption or defeasance
thereof,  prior to its scheduled  maturity;  provided that this clause (g) shall
not apply to secured  Indebtedness that becomes due as a result of the voluntary
sale or transfer of the property or assets securing such Indebtedness;

         (h) Any Borrower or any Material  Subsidiary shall commence a voluntary
case or other proceeding  seeking  liquidation,  reorganization  or other relief
with  respect  to  itself or its debts  under  any  bankruptcy,  reorganization,
compromise,   arrangement,   insolvency,   readjustment  of  debt,  dissolution,
liquidation or other similar law of any  jurisdiction now or hereafter in effect
(herein called the "Bankruptcy Law") or shall seek the appointment of a trustee,
receiver,  liquidator,  custodian  or  other  similar  official  of  it  or  any
substantial  part of its Property,  or shall consent to, approve or acquiesce in
any  such  relief  or to the  commencement  of any  involuntary  case  or  other
proceeding  described  in clause  (i) below or to the  appointment  of or taking
possession  by any such  official in any  involuntary  case or other  proceeding
commenced  against  it, or shall make a general  assignment  for the  benefit of
creditors, or shall fail generally to pay its debts as they become due, or shall
take any corporate action to authorize any of the foregoing;

         (i) an involuntary case or other proceeding shall be commenced  against
any Borrower or any Material Subsidiary seeking  liquidation,  reorganization or
other relief with respect to its debts under any  Bankruptcy  Law or seeking the
appointment  of a trustee,  receiver,  liquidator,  custodian  or other  similar
official of it or any  substantial  part of its property,  and such  involuntary
case or other proceeding  shall remain  undismissed and unstayed for a period of
60 days;  or an order for relief  shall be entered  against any  Borrower or any
Material  Subsidiary  under any Bankruptcy Laws or an order,  judgment or decree
shall be entered appointing any such trustee, receiver, custodian, liquidator or
similar official;

         (j) Any Subsidiary  Borrower  becomes  insolvent,  is unable to pay its
debts as they fall due, stops,  suspends or threatens to stop or suspend payment
of all or  substantially  all of its debts,  begins  negotiations  to  readjust,
reschedule or defer all or substantially all of its Indebtedness  (which it will
otherwise  be unable to pay when due) or proposes or makes a general  assignment
or an arrangement  or composition  with or for the benefit of its creditors or a
moratorium is agreed or declared in respect of or affecting all or substantially
all of the Indebtedness of such Subsidiary Borrower;

         (k) The Company or any ERISA  Affiliate shall fail to pay when due (and
not being contested in good faith) an amount or amounts aggregating in excess of
the ERISA  Obligation  Threshold which it shall have become liable to pay to the
PBGC,  the  Internal  Revenue  Service  or  the  Department  of  Labor  or  to a
Multiemployer  Plan under Title IV of ERISA;  or notice of intent to terminate a
Plan or Plans  having  aggregate  Unfunded  Benefit  Liabilities  in  excess  of
$50,000,000  (collectively,  a "Material Plan") shall be filed under Title IV of
ERISA by the  Company  or any ERISA  Affiliate,  any plan  administrator  or any
combination  of the foregoing;  or the PBGC shall  institute  proceedings  under
Title IV of ERISA to  terminate,  to impose  liability  (other than for premiums
under Section 4007 of ERISA) in respect of or to cause a trustee to be appointed
to  administer  any  Material  Plan;  or there shall occur a complete or partial
withdrawal  from,  or a default,  within the  meaning of Section  4219(c)(5)  of

has a  substantially  equivalent  effect  to  any  of the  events  mentioned  in
paragraphs (h), (i), (j) (k) or (l) of this Section;

then,  and in every such event (other than an event with respect to any Borrower
described  in clause  (h) or (i) of this  Article),  and at any time  thereafter
during the continuance of such event, (i) the  Administrative  Agent may, and at
the request of the Required Lenders shall, by notice to the Company, take either
or both of the following  actions,  at the same or different times (A) terminate
the  Commitments  and thereupon the  Commitments  shall  terminate  immediately,
and/or (B) declare the Loans then  outstanding  (together with accrued  interest
thereon and all fees and all other  amounts  payable  hereunder) to be, and such
amounts shall thereupon become, immediately due and payable without presentment,
demand, protest,  notice to accelerate,  notice of intent to accelerate or other
notice of any kind,  all of which are hereby waived by each  Borrower;  provided

                                   ARTICLE IX

                            The Administrative Agent

         Each of the Lenders  hereby  irrevocably  appoints  the  Administrative
Agent as its agent and authorizes the Administrative  Agent to take such actions
on its behalf and to exercise such powers as are delegated to the Administrative
Agent by the  terms  hereof,  together  with  such  actions  and  powers  as are
reasonably incidental thereto.

         The bank serving as the  Administrative  Agent hereunder shall have the
same rights and powers in its  capacity as a Lender as any other  Lender and may
exercise the same as though it were not the Administrative  Agent, and such bank
and its Affiliates may accept deposits from, lend money to and generally  engage
in any kind of business with each Borrower or any Subsidiary or other  Affiliate
thereof as if it were not the Administrative Agent hereunder.

         The  Administrative  Agent  shall not have any  duties  or  obligations
except those expressly set forth herein.  Without limiting the generality of the
foregoing, (a) the Administrative Agent shall not be subject to any fiduciary or
other  implied  duties,  regardless  of whether a Default  has  occurred  and is
continuing,  (b) the  Administrative  Agent  shall not have any duty to take any
discretionary action or exercise any discretionary  powers, except discretionary
rights and powers expressly contemplated hereby that the Administrative Agent is
required to exercise in writing by the Required Lenders (or such other number or
percentage  of the  Lenders as shall be  necessary  under the  circumstances  as
provided in Section  10.02),  and (c) except as expressly set forth herein,  the
Administrative  Agent  shall  not have any duty to  disclose,  and  shall not be
liable for the failure to disclose,  any information relating to any Borrower or
any of its Subsidiaries  that is communicated to or obtained by the bank serving
as  Administrative  Agent  or  any  of  its  Affiliates  in  any  capacity.  The
Administrative Agent shall not be liable for any action taken or not taken by it
with the consent or at the request of the Required Lenders (or such other number
or percentage of the Lenders as shall be necessary  under the  circumstances  as
provided  in Section  10.02) or in the  absence of its own gross  negligence  or
wilful  misconduct.  The  Administrative  Agent  shall  be  deemed  not to  have
knowledge of any Default unless and until written notice thereof is given to the
Administrative  Agent by any Borrower or a Lender, and the Administrative  Agent
shall not be  responsible  for or have any duty to ascertain or inquire into (i)
any statement,  warranty or  representation  made in or in connection  with this
Agreement,  (ii) the  contents  of any  certificate,  report  or other  document
delivered  hereunder  or  in  connection  herewith,  (iii)  the  performance  or
observance of any of the covenants,  agreements or other terms or conditions set
forth herein, (iv) the validity, enforceability, effectiveness or genuineness of
this  Agreement  or any other  agreement,  instrument  or  document,  or (v) the
satisfaction of any condition set forth in Article IV or elsewhere herein, other
than to confirm  receipt of items  expressly  required  to be  delivered  to the
Administrative Agent.

         The Administrative  Agent shall be entitled to rely upon, and shall not
incur any liability for relying upon, any notice, request, certificate, consent,
statement,  instrument,  document or other writing  believed by it to be genuine
and to have been signed or sent by the proper Person. The  Administrative  Agent
also may rely upon any statement  made to it orally or by telephone and believed
by it to be made by the proper  Person,  and shall not incur any  liability  for
relying thereon.  The  Administrative  Agent may consult with legal counsel (who
may be counsel for the  Borrowers),  independent  accountants  and other experts
selected by it, and shall not be liable for any action  taken or not taken by it
in accordance with the advice of any such counsel, accountants or experts.

         The  Administrative  Agent  may  perform  any and all  its  duties  and
exercise  its  rights  and  powers  by or  through  any one or  more  sub-agents
appointed by the  Administrative  Agent. The  Administrative  Agent and any such
sub-agent  may perform any and all its duties and exercise its rights and powers
through their  respective  Related  Parties.  The exculpatory  provisions of the
preceding  paragraphs  shall  apply to any  such  sub-agent  and to the  Related
Parties of the Administrative  Agent and any such sub-agent,  and shall apply to
their  respective  activities in connection  with the  syndication of the credit
facilities provided for herein as well as activities as Administrative Agent.

         Subject to the appointment and acceptance of a successor Administrative
Agent as provided in this paragraph,  the Administrative Agent may resign at any
time by notifying the Lenders and each Borrower.  Upon any such resignation,  so
long as no Default exists, the Company shall have the right, with the consent of
the Required Lenders, such consent not to be unreasonably withheld, to appoint a
successor.  If a Default  exists,  the Required  Lenders shall have the right to
appoint a successor without the consent of the Company or any other Borrower. If
no  successor  shall  have been so  appointed  by the  Company  or the  Required
Lenders, as applicable,  and shall have accepted such appointment within 30 days
after the retiring  Administrative  Agent gives notice of its resignation,  then
the  retiring  Administrative  Agent may,  on behalf of the  Lenders,  appoint a
successor  Administrative Agent which shall be a bank with an office in New York
City,  New York,  or an  Affiliate  of any such  bank,  and which has a combined
capital  and  surplus  of at  least  $500,000,000.  Upon the  acceptance  of its
appointment as  Administrative  Agent  hereunder by a successor,  such successor
shall succeed to and become vested with all the rights,  powers,  privileges and
duties of the retiring  Administrative  Agent,  and the retiring  Administrative
Agent shall be discharged  from its duties and obligations  hereunder.  The fees
payable by the Company to a successor  Administrative Agent shall be the same as
those payable to its predecessor unless otherwise agreed between the Company and
such successor.  After the Administrative  Agent's  resignation  hereunder,  the
provisions  of this Article and Section  10.03 shall  continue in effect for the
benefit  of  such  retiring  Administrative  Agent,  its  sub-agents  and  their
respective  Related  Parties in respect  of any  actions  taken or omitted to be
taken by any of them while it was acting as Administrative Agent.

         Each  Lender  acknowledges  that  it  has,  independently  and  without
reliance  upon the  Administrative  Agent or any other  Lender and based on such
documents  and  information  as it has deemed  appropriate,  made its own credit
analysis  and  decision  to  enter  into  this   Agreement.   Each  Lender  also
acknowledges  that  it  will,   independently  and  without  reliance  upon  the
Administrative  Agent  or any  other  Lender  and  based on such  documents  and
information as it shall from time to time deem appropriate, continue to make its
own decisions in taking or not taking action under or based upon this Agreement,
any related agreement or any document furnished hereunder or thereunder.

         SECTION  10.02.  Waivers;  Amendments.  (a) No  failure or delay by the
Administrative  Agent or any Lender in exercising  any right or power  hereunder
shall operate as a waiver thereof,  nor shall any single or partial  exercise of
any such  right or  power,  or any  abandonment  or  discontinuance  of steps to
enforce such a right or power, preclude any other or further exercise thereof or
the  exercise  of any other  right or power.  The  rights  and  remedies  of the
Administrative  Agent  and the  Lenders  hereunder  are  cumulative  and are not
exclusive of any rights or remedies that they would otherwise have. No waiver of
any  provision  of this  Agreement  or consent to any  departure by any Borrower
therefrom shall in any event be effective  unless the same shall be permitted by
paragraph  (b) of this  Section,  and  then  such  waiver  or  consent  shall be
effective  only in the  specific  instance  and for the purpose for which given.
Without limiting the generality of the foregoing, the making of a Loan shall not
be  construed  as  a  waiver  of  any   Default,   regardless   of  whether  the
Administrative  Agent or any  Lender may have had  notice or  knowledge  of such
Default at the time.

                  (b) Neither this  Agreement  nor any  provision  hereof may be
waived,  amended or modified  except  pursuant to an agreement or  agreements in
writing entered into by each Borrower and the Required Lenders, or each Borrower
and the Administrative Agent with the consent of the Required Lenders;  provided
that no such  agreement  shall (i) increase the Commitment of any Lender without
the written consent of such Lender,  (ii) increase the maximum amount  available
under the Foreign  Available  Amount without the written  consent of each Lender
affected thereby, such consent not to be unreasonably withheld, (iii) reduce the
principal amount of any Loan or reduce the rate of interest  thereon,  or reduce
any fees payable hereunder,  without the written consent of each Lender affected
thereby,  (iv) postpone the scheduled date of payment of the principal amount of
any Loan, or any interest thereon, or any fees payable hereunder,  or reduce the
amount of, waive or excuse any such payment,  or postpone the scheduled  date of
expiration  of any  Commitment,  without  the  written  consent  of each  Lender
affected thereby, (v) change Section 2.16(b) or (c) in a manner that would alter
the pro rata sharing of payments required  thereby,  without the written consent
of each  Lender,  (vi)  change  any of the  provisions  of this  Section  or the
definition of "Required  Lenders" or any other provision  hereof  specifying the
number or  percentage of Lenders  required to waive,  amend or modify any rights
hereunder or make any determination or grant any consent hereunder,  without the
written  consent of each Lender,  (vii) change any of the  provisions of Section
10.04(a)  without the written consent of each Lender,  (viii) change the Type of
Loans  available  or the  currencies  in which Loans are  available  without the
written  consent  of each  Lender,  (ix)  permit a change  in  ownership  of any
Subsidiary  Borrower  unless  the  Company  maintains  100%  direct or  indirect
ownership  without the written consent of each Lender or (x) release the Company
from its  obligations  under  Article VII  without  the written  consent of each
Lender; provided further that no such agreement shall amend, modify or otherwise
affect the rights or duties of the  Administrative  Agent hereunder  without the
prior written consent of the Administrative Agent.

         SECTION 10.03.  Expenses;  Indemnity;  Damage Waiver. (a) The Borrowers
shall  pay  (i)  all   reasonable   out-of-pocket   expenses   incurred  by  the
Administrative Agent and its Affiliates,  including the reasonable fees, charges
and  disbursements  of Vinson & Elkins  L.L.P.,  counsel  to the  Administrative
Agent, in connection with the syndication of the credit facilities  provided for
herein,  reasonable publicity expenses agreed to by the Company, the preparation
and administration of this Agreement or any amendments, modifications or waivers
of the provisions hereof (whether or not the transactions contemplated hereby or
thereby shall be consummated),  and (ii) all out-of-pocket  expenses incurred by
the  Administrative  Agent  or any  Lender,  including  the  fees,  charges  and
disbursements  of any counsel  for the  Administrative  Agent or any Lender,  in
connection  with the  enforcement or protection of its rights in connection with
this Agreement,  including its rights under this Section,  or in connection with
the Loans made hereunder,  including all such  out-of-pocket  expenses  incurred
during any workout, restructuring or negotiations in respect of such Loans.

                  (b) The Borrowers shall indemnify the Administrative Agent and
each Lender,  and each Related Party of any of the foregoing  Persons (each such
Person being called an "Indemnitee")  against, and hold each Indemnitee harmless
from, any and all losses,  claims,  damages,  liabilities and related  expenses,
including the reasonable fees,  charges and disbursements of any counsel for any
Indemnitee,  incurred by or asserted  against any Indemnitee  arising out of, in
connection  with,  or as a  result  of (i) the  execution  or  delivery  of this
Agreement or any agreement or instrument contemplated hereby, the performance by
the parties hereto of their respective obligations hereunder or the consummation
of the Transactions or any other transactions contemplated hereby, (ii) any Loan
or the use of the proceeds  therefrom,  (iii) any actual or alleged  presence or
release of Hazardous  Materials on or from any property owned or operated by any
Borrower or any of its Subsidiaries,  or any Environmental  Liability related in
any way to any  Borrower  or any of its  Subsidiaries,  or (iv)  any  actual  or
prospective claim,  litigation,  investigation or proceeding  relating to any of
the  foregoing,  whether  based  on  contract,  tort  or any  other  theory  and
regardless  of whether any  Indemnitee  is a party  thereto;  provided that such
indemnity shall not, as to any Indemnitee,  be available to the extent that such
losses, claims, damages, liabilities or related expenses resulted from the gross
negligence or wilful misconduct of such Indemnitee.

                  (c) To the extent  that any  Borrower  fails to pay any amount
required to be paid by it to the Administrative Agent under paragraph (a) or (b)
of this  Section,  each  Lender  severally  agrees to pay to the  Administrative
Agent, such Lender's Applicable  Percentage  (determined as of the time that the
applicable  unreimbursed  expense or indemnity payment is sought) of such unpaid
amount;  provided that the  unreimbursed  expense or  indemnified  loss,  claim,
damage,  liability  or related  expense,  as the case may be, was incurred by or
asserted against the Administrative Agent in its capacity as such.

                  (d) To the extent  permitted by applicable  law, each Borrower
shall not assert,  and hereby waive,  any claim against any  Indemnitee,  on any
theory of liability,  for special,  indirect,  consequential or punitive damages
(as opposed to direct or actual damages)  arising out of, in connection with, or
as a result of, this  Agreement  or any  agreement  or  instrument  contemplated
hereby, the Transactions, any Loan or the use of the proceeds thereof.

                  (e) All  amounts  due  under  this  Section  shall be  payable
promptly after written demand therefor.

         SECTION  10.04.  Successors  and Assigns.  (a) The  provisions  of this
Agreement  shall be binding upon and inure to the benefit of the parties  hereto
and their  respective  successors and assigns  permitted  hereby,  except that a
Borrower may not assign or otherwise  transfer any of its rights or  obligations
hereunder  without the prior  written  consent of each Lender (and any attempted
assignment  or transfer by a Borrower  without  such  consent  shall be null and
void).  Nothing in this Agreement,  expressed or implied,  shall be construed to
confer  upon  any  Person  (other  than the  parties  hereto,  their  respective
successors  and  assigns   permitted   hereby  and,  to  the  extent   expressly
contemplated hereby, the Related Parties of each of the Administrative Agent and
the Lenders) any legal or equitable right, remedy or claim under or by reason of
this Agreement.

                  (b) Any Lender may  assign to one or more  assignees  all or a
portion of its rights and obligations  under this Agreement  (including all or a
portion of its Commitment and the Loans at the time owing to it); provided, that
(i) except in the case of an assignment  to a Lender,  an Affiliate of a Lender,
or  to  the  United  States  Federal  Reserve  Banks,   each  Borrower  and  the
Administrative  Agent must give their prior written  consent to such  assignment
(which consent shall not be unreasonably  withheld),  (ii) except in the case of
an  assignment  of  the  entire  remaining  amount  of  the  assigning  Lender's
Commitment, the amount of the Commitment of the assigning Lender subject to each
such  assignment  (determined as of the date the Assignment and Acceptance  with
respect to such assignment is delivered to the  Administrative  Agent) shall not
be less than  $5,000,000,  (iii)  each  partial  assignment  shall be made as an
assignment  of a  proportionate  part of all the assigning  Lender's  rights and
obligations under this Agreement,  except that this clause (iii) shall not apply
to rights in respect of outstanding  Competitive Loans, (iv) the parties to each
assignment shall execute and deliver to the  Administrative  Agent an Assignment
and Acceptance,  together with a processing and  recordation fee of $3,500,  and
(v)  the  assignee,  if  it  shall  not  be  a  Lender,  shall  deliver  to  the
Administrative Agent an administrative questionnaire in the form supplied by the
Administrative  Agent;  and provided  further that any consent of the  Borrowers
otherwise  required  under this  paragraph  shall not be required if an Event of
Default has occurred and is  continuing.  Subject to  acceptance  and  recording
thereof pursuant to paragraph (d) of this Section,  from and after the effective
date specified in each Assignment and Acceptance,  the assignee thereunder shall
be a party hereto and, to the extent of the interest assigned by such Assignment
and  Acceptance,  have  the  rights  and  obligations  of a  Lender  under  this
Agreement,  and the  assigning  Lender  thereunder  shall,  to the extent of the
interest  assigned by such  Assignment  and  Acceptance,  be  released  from its
obligations  under  this  Agreement  (and,  in the  case  of an  Assignment  and
Acceptance  covering all of the assigning  Lender's rights and obligations under
this Agreement,  such Lender shall cease to be a party hereto but shall continue
to be entitled to the  benefits of Sections  2.13,  2.14,  2.15 and 10.03).  Any
assignment or transfer by a Lender of rights or obligations under this Agreement
that does not comply with this  paragraph  shall be treated for purposes of this
Agreement  as a sale by such  Lender  of a  participation  in  such  rights  and
obligations in accordance with paragraph (e) of this Section.

                  (c) The  Administrative  Agent,  acting for this purpose as an
agent of all  Borrowers,  shall maintain at one of its offices in New York City,
New  York,  a copy of  each  Assignment  and  Acceptance  delivered  to it and a
register for the recordation of the names and addresses of the Lenders,  and the
Commitment of, and principal  amount of the Loans owing to, each Lender pursuant
to the terms  hereof  from time to time (the  "Register").  The  entries  in the
Register shall be conclusive,  and each Borrower,  the Administrative  Agent and
the  Lenders  may treat each  Person  whose  name is  recorded  in the  Register
pursuant  to the terms  hereof as a Lender  hereunder  for all  purposes of this
Agreement,  notwithstanding  notice  to the  contrary.  The  Register  shall  be
available for inspection by any Borrower and any Lender,  at any reasonable time
and from time to time upon reasonable prior notice.

                  (d)  Upon  its  receipt  of a duly  completed  Assignment  and
Acceptance  executed by an  assigning  Lender and an  assignee,  the  assignee's
completed   administrative   questionnaire   in  the   form   supplied   by  the
Administrative  Agent (unless the assignee shall already be a Lender hereunder),
the processing and  recordation fee referred to in paragraph (b) of this Section
and any written  consent to such  assignment  required by paragraph  (b) of this
Section,  the  Administrative  Agent shall accept such Assignment and Acceptance
and record the  information  contained  therein in the  Register.  No assignment
shall be effective for purposes of this Agreement unless it has been recorded in
the Register as provided in this paragraph.

                  (e) Any Lender may, without the consent of any Borrower or the
Administrative Agent, sell participations to one or more banks or other entities
(a  "Participant")  in all or a portion of such Lender's  rights and obligations
under this Agreement (including all or a portion of its Commitment and the Loans
owing to it);  provided that (i) such Lender's  obligations under this Agreement
shall remain unchanged,  (ii) such Lender shall remain solely responsible to the
other parties  hereto for the  performance  of such  obligations  and (iii) each
Borrower,  the Administrative Agent and the other Lenders shall continue to deal
solely and directly with such Lender in connection with such Lender's rights and
obligations under this Agreement.  Any agreement or instrument pursuant to which
a Lender sells such a participation  shall provide that such Lender shall retain
the  sole  right  to  enforce  this  Agreement  and to  approve  any  amendment,
modification  or waiver of any provision of this  Agreement;  provided that such
agreement  or  instrument  may provide  that such  Lender will not,  without the
consent  of the  Participant,  agree to any  amendment,  modification  or waiver
described  in  the  first   proviso  to  Section   10.02(b)  that  affects  such
Participant. Subject to paragraph (f) of this Section, each Borrower agrees that
each  Participant  shall be entitled to the benefits of Sections 2.13,  2.14 and
2.15 to the same extent as if it were a Lender and had  acquired its interest by
assignment pursuant to paragraph (b) of this Section. To the extent permitted by
law, each Participant also shall be entitled to the benefits of Section 10.08 as
though it were a Lender;  provided  such  Participant  agrees to be  subject  to
Section 2.16(c) and 2.17 as though it were a Lender.

                  (f) A Participant shall not be entitled to receive any greater
payment  under Section 2.13 or 2.15 than the  applicable  Lender would have been
entitled to receive with respect to the participation  sold to such Participant,
unless  the  sale of the  participation  to such  Participant  is made  with the
Company's prior written consent. A Participant that would be a Foreign Lender if
it were a Lender  shall not be entitled to the  benefits of Section  2.15 unless
each Borrower is notified of the participation sold to such Participant and such
Participant  agrees,  for the benefit of each  Borrower,  to comply with Section
2.15(e) as though it were a Lender.

                  (g) Any  Lender  may at any time  pledge or assign a  security
interest  in all or any  portion of its rights  under this  Agreement  to secure
obligations  of such  Lender,  including  any  pledge  or  assignment  to secure
obligations to a United States Federal  Reserve Bank, and this Section shall not
apply to any such pledge or assignment of a security interest;  provided that no
such pledge or assignment of a security interest shall release a Lender from any
of its obligations hereunder or substitute any such pledgee or assignee for such
Lender as a party hereto.

                  (h) Any assignee or Participant under this Section 10.04 shall
have an office or a branch or an  Affiliate  available  to it and located in the
appropriate jurisdiction through which such assignee or Participant can make any
Eurodollar Loan or a Loan denominated in an Alternate Currency as required under
this Agreement.

                  (i) Notwithstanding anything to the contrary contained herein,
any Lender (a "Granting  Lender") may grant to a special purpose funding vehicle
(an "SPC") sponsored by such Granting Lender, identified as such in writing from
time to time by the Granting Lender to the Administrative Agent and the Company,
the  option  to  provide  to the  Company  all or any part of any Loan that such
Granting Lender would otherwise be obligated to make to the Borrower pursuant to
this Agreement,  provided that (i) nothing herein shall  constitute a commitment
by any SPC to make  any  Loan and (ii) if an SPC  elects  not to  exercise  such
option or otherwise  fails to provide all or any part of such Loan, the Granting
Lender shall be obligated to make such Loan  pursuant to the terms  hereof.  The
making  of a  Revolving  Credit  Loan  by an SPC  hereunder  shall  utilize  the
Commitment of the Granting Lender to the same extent,  and as if, such Loan were
made by the Granting  Lender.  Each party hereto hereby agrees that no SPC shall
be  liable  for any  payment  under  this  Agreement  for  which a Lender  would
otherwise  be liable (all  liability  for which,  if any,  shall remain with the
Granting  Lender).  In furtherance  of the  foregoing,  each party hereto hereby
agrees (which  agreement shall survive the termination of this Agreement)  that,
prior  to the  date  that is one year  and one day  after  the  later of (A) the
payment in full of all outstanding commercial paper or other senior indebtedness
of any SPC and (B) the  Revolving  Loan  Maturity  Date,  it will not  institute
against,  or  join  any  other  person  in  instituting  against,  such  SPC any
bankruptcy,  reorganization,  arrangement, insolvency or liquidation proceedings
or similar proceedings under the laws of the United States or any state thereof.
In addition,  notwithstanding anything to the contrary contained in this Section
10.04,  any SPC may, with notice to, but without  prior written  consent of, the
Company,  any Subsidiary Borrower or the Administrative Agent and without paying
any  processing  fee  therefor,  assign all or a portion of its interests in any
Loans  to  the  Granting  Lender  or to  any  financial  institutions  providing
liquidity  and/or  credit  support to or for the account of such SPC to fund the
Loans made by such SPC or to support the  securities (if any) issued by such SPC
to  fund  such  Loans  and  disclose  on a  confidential  basis  any  non-public
information relating to its Loans to any rating agency,  commercial paper dealer
or provider of any surety,  guarantee or liquidity or credit enhancement to such
SPC.

         SECTION 10.05. Survival. All covenants, agreements, representations and
warranties  made  by  any  Borrower  herein  and in the  certificates  or  other
instruments  delivered in connection with or pursuant to this Agreement shall be
considered  to have been  relied  upon by the  other  parties  hereto  and shall
survive  the  execution  and  delivery of this  Agreement  and the making of any
Loans,  regardless of any  investigation  made by any such other party or on its
behalf and notwithstanding  that the Administrative Agent or any Lender may have
had notice or knowledge of any Default or incorrect  representation  or warranty
at the time any credit is extended  hereunder,  and shall continue in full force
and effect as long as the  principal  of or any accrued  interest on any Loan or
any fee or any other amount  payable  under this  Agreement is  outstanding  and
unpaid  and so long as the  Commitments  have not  expired  or  terminated.  The
provisions of Sections  2.13,  2.14,  2.15 and 10.03 shall survive and remain in
full  force  and  effect  regardless  of the  consummation  of the  transactions
contemplated  hereby,  the repayment of the Loans, the expiration or termination
of the Commitments or the termination of this Agreement or any provision hereof.

         SECTION 10.06. Counterparts; Integration; Effectiveness. This Agreement
may be executed in  counterparts  (and by different  parties hereto on different
counterparts), each of which shall constitute an original, but all of which when
taken  together  shall  constitute a single  contract.  This  Agreement  and any
separate letter  agreements  with respect to fees payable to the  Administrative
Agent  constitute the entire contract among the parties  relating to the subject
matter hereof and supersede any and all previous  agreements and understandings,
oral or written,  relating to the subject matter  hereof.  Except as provided in
Section 4.01,  this  Agreement  shall become  effective  when it shall have been
executed by the  Administrative  Agent and when the  Administrative  Agent shall
have  received  counterparts  hereof  which,  when  taken  together,   bear  the
signatures of each of the other parties hereto,  and thereafter shall be binding
upon and  inure to the  benefit  of the  parties  hereto  and  their  respective
successors and assigns.  Delivery of an executed counterpart of a signature page
of this  Agreement  by  telecopy  shall be  effective  as delivery of a manually
executed counterpart of this Agreement.

         SECTION 10.07. Severability. Any provision of this Agreement held to be
invalid,  illegal  or  unenforceable  in  any  jurisdiction  shall,  as to  such
jurisdiction,  be  ineffective to the extent of such  invalidity,  illegality or
unenforceability without affecting the validity,  legality and enforceability of
the remaining provisions hereof; and the invalidity of a particular provision in
a  particular  jurisdiction  shall not  invalidate  such  provision in any other
jurisdiction.

         SECTION  10.08.  Right of  Setoff.  If an Event of  Default  shall have
occurred and be  continuing,  each Lender and each of its  Affiliates  is hereby
authorized at any time and from time to time, to the fullest extent permitted by
law, to set off and apply any and all  deposits  (general  or  special,  time or
demand, provisional or final) at any time held and other obligations at any time
owing by such  Lender or  Affiliate  to or for the credit or the  account of any
Borrower  against  any of and  all  the  obligations  of  such  Borrower  now or
hereafter  existing under this Agreement  held by such Lender,  irrespective  of
whether or not such Lender shall have made any demand under this  Agreement  and
although such obligations may be unmatured. The rights of each Lender under this
Section are in addition to other rights and remedies  (including other rights of
setoff) which such Lender may have.

         SECTION  10.09.  Governing  Law;  Jurisdiction;  Consent to  Service of
Process. (a) This Agreement shall be  construed  in accordance with and governed
by the law of the State of New York.

                  (b)  Each  Borrower  hereby  irrevocably  and  unconditionally
submits,  for itself and its property,  to the nonexclusive  jurisdiction of the
Supreme  Court of the State of New York  sitting  in New York  County and of the
United  States  District  Court of the  Southern  District of New York,  and any
appellate court from any thereof,  in any action or proceeding arising out of or
relating to this  Agreement,  or for recognition or enforcement of any judgment,
and each of the parties hereto hereby  irrevocably  and  unconditionally  agrees
that all  claims in respect of any such  action or  proceeding  may be heard and
determined  in such New York State or, to the extent  permitted  by law, in such
Federal  court.  Each of the parties  hereto agrees that a final judgment in any
such  action or  proceeding  shall be  conclusive  and may be  enforced in other
jurisdictions  by suit on the judgment or in any other  manner  provided by law.
Nothing in this Agreement shall affect any right that the  Administrative  Agent
or any Lender may otherwise  have to bring any action or proceeding  relating to
this  Agreement  against  any  Borrower or its  properties  in the courts of any
jurisdiction.

                  (c)  Each  Borrower  hereby  irrevocably  and  unconditionally
waives,  to the  fullest  extent  it may  legally  and  effectively  do so,  any
objection which it may now or hereafter have to the laying of venue of any suit,
action or proceeding  arising out of or relating to this  Agreement in any court
referred to in paragraph (b) of this Section.  Each of the parties hereto hereby
irrevocably  waives,  to the fullest extent  permitted by law, the defense of an
inconvenient  forum to the  maintenance of such action or proceeding in any such
court.

                  (d)  Each  party to this  Agreement  irrevocably  consents  to
service  of  process  to the  General  Counsel  of  the  Company  at  Kerr-McGee
Corporation, 123 Robert S. Kerr Avenue, Oklahoma City, Oklahoma, 73102 (Telecopy
No.  (405)  270-4211).  Nothing in this  Agreement  will affect the right of any
party to this Agreement to serve process in any other manner permitted by law.

         SECTION 10.10.  WAIVER OF JURY TRIAL.  EACH PARTY HERETO HEREBY WAIVES,
TO THE FULLEST  EXTENT  PERMITTED BY APPLICABLE  LAW, ANY RIGHT IT MAY HAVE TO A
TRIAL BY JURY IN ANY LEGAL PROCEEDING  DIRECTLY OR INDIRECTLY  ARISING OUT OF OR
RELATING TO THIS  AGREEMENT OR THE  TRANSACTIONS  CONTEMPLATED  HEREBY  (WHETHER
BASED ON CONTRACT,  TORT OR ANY OTHER  THEORY).  EACH PARTY HERETO (A) CERTIFIES
THAT NO  REPRESENTATIVE,  AGENT OR ATTORNEY OF ANY OTHER PARTY HAS  REPRESENTED,
EXPRESSLY  OR  OTHERWISE,  THAT SUCH  OTHER  PARTY  WOULD  NOT,  IN THE EVENT OF
LITIGATION,  SEEK TO ENFORCE THE FOREGOING WAIVER AND (B)  ACKNOWLEDGES  THAT IT
AND THE OTHER PARTIES  HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY,
AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

         SECTION 10.11. Headings.  Article and Section headings and the Table of
Contents used herein are for convenience of reference only, are not part of this
Agreement  and  shall  not  affect  the   construction  of,  or  be  taken  into
consideration in interpreting, this Agreement.

         SECTION 10.12.  Confidentiality.  Each of the Administrative  Agent and
the Lenders  agrees to  maintain  the  confidentiality  of the  Information  (as
defined  below),  except that  Information  may be disclosed  (a) to its and its
Affiliates' directors,  officers,  employees and agents,  including accountants,
legal counsel and other advisors (it being  understood  that the Persons to whom
such  disclosure  is made will be  informed of the  confidential  nature of such
Information and instructed to keep such  Information  confidential),  (b) to the
extent  requested by any  regulatory  authority,  (c) to the extent  required by
applicable laws or regulations or by any subpoena or similar legal process,  (d)
to any other party to this Agreement, (e) in connection with the exercise of any
remedies hereunder or any suit, action or proceeding  relating to this Agreement
or the enforcement of rights hereunder,  (f) subject to an agreement  containing
provisions  substantially the same as those of this Section,  to any assignee of
or Participant in, or any prospective  assignee of or Participant in, any of its
rights or obligations under this Agreement,  (g) with the consent of the Company
or (h) to the extent such Information (i) becomes publicly  available other than
as a  result  of a breach  of this  Section  or (ii)  becomes  available  to the
Administrative  Agent or any  Lender on a  nonconfidential  basis  from a source
other than a Borrower. For the purposes of this Section, "Information" means all
information  received  from  any  Borrower  relating  to  such  Borrower  or its
business,   other  than  any  such   information   that  is   available  to  the
Administrative  Agent  or  any  Lender  on  a  nonconfidential  basis  prior  to
disclosure by such Borrower;  provided that, in the case of information received
from such Borrower after the date hereof, such information is clearly identified
at the time of delivery as  confidential.  Any Person  required to maintain  the
confidentiality  of  Information as provided in this Section shall be considered
to have complied  with its  obligation to do so if such Person has exercised the
same degree of care to maintain the  confidentiality of such Information as such
Person would accord to its own confidential information.

         SECTION  10.13.  Currency  Indemnity.  (a) If any amount payable by any
Borrower under or in connection with any Loan or any other  obligation  under or
in  connection  herewith is received by any Lender in a currency  (the  "Payment
Currency")  other than that agreed to be payable in this  Agreement (the "Agreed
Currency"),  whether as a result of any judgment or order or the  enforcement of
the same, the  liquidation of such Borrower or otherwise and the amount produced
by  converting  the Payment  Currency so  received  into the Agreed  Currency at
market rates  prevailing at or about the time of receipt of the Payment Currency
is less than the amount of the Agreed  Currency  due with  respect to such Loan,
then such Borrower and the Company shall and hereby does, as an independent  and
additional  obligation,  indemnify  each Lender for the  deficiency and any loss
sustained as a result.

                  (b)  The  above  indemnity  shall   constitute   separate  and
independent  obligations of each Borrower from its other  obligations under this
Agreement  and  shall  apply  irrespective  of  any  indulgence  granted  by the
Administrative Agent or any Lender. The applicable Borrower shall pay reasonable
costs of making any conversion from the Payment Currency to the Agreed Currency.

                  (c) Each  Borrower  hereby waives any right it may have in any
jurisdiction  to pay any amount due and owing hereunder in a currency other than
that which it is expressed to be payable under the terms and  conditions of this
Agreement.

         SECTION 10.14. Subsidiary Borrower Several Obligations. The obligations
of each Subsidiary  Borrower under this Agreement are several and the failure of
any Subsidiary  Borrower to perform its  obligations  under this Agreement shall
not affect the  obligations of any Borrower  towards any of the other parties to
this Agreement.

                  (b) No  assurance,  security  or payment  which may be avoided
under any laws relating to  bankruptcy,  insolvency or corporate  reorganization
and no release, settlement or discharge of any of the Subsidiary Borrowers which
may have been  given or made on the  faith of any such  assurance,  security  or
payment,  shall prejudice or affect the right of the Administrative Agent or any
Lender to recover from any other  Subsidiary  Borrower to the full extent of its
obligations  under  this  Agreement  just  as if  such  release,  settlement  or
discharge had not occurred.

                  (c) Each  Subsidiary  Borrower hereby waives any rights it may
have under applicable law which may at any time be inconsistent  with any of the
provisions  of this  Agreement  or  which it may  have of  first  requiring  the
Administrative  Agent or any Lender to proceed  against  or claim  payment  from
another Borrower or any other party or parties. It is further agreed that all or
any of the  Administrative  Agent and the Lenders,  without notice to any of the
Subsidiary  Borrowers and without affecting or impairing the obligations of such
Subsidiary  Borrowers  hereunder,  may  grant  time,  indulgences,  concessions,
releases and  discharges  to, may take  securities  from and give the same,  may
accept compositions from and may otherwise deal with each other Borrower and all
other  parties as they may see fit and  generally may otherwise do or omit to do
any act or thing  which,  but for this  provision,  might  operate  to affect or
impair  the  obligations  of each of the  Subsidiary  Borrowers  hereunder.  The
obligations  of the  Subsidiary  Borrowers  hereunder  shall not be  affected or
impaired by any amendment or modification hereto.

         SECTION 10.15.  Joint and Several  Obligations of the Company.  (a) The
liability  of  the  Company  under  this  Agreement  with  respect  to  its  own
obligations and the obligations of each Subsidiary Borrower is joint and several
and therefore,  without prejudice to any other provision of this Agreement,  the
Company hereby unconditionally and irrevocably undertakes, as principal obligor,
to  the  Administrative   Agent  and  the  Lenders  the  due  and  unconditional
performance  and discharge by each of the other Borrowers of all the obligations
expressed to be binding upon such Borrowers hereunder as the same may be amended
from time to time (the "Relevant  Obligations") and, without limitation,  agrees
with the  Administrative  Agent and the Lenders that if and whenever at any time
and from  time to time any of the  other  Borrowers  shall  fail to  perform  or
discharge  or shall  otherwise  be in default in respect of any of the  Relevant
Obligations it shall discharge and make good the default as if it instead of the
relevant other Borrower was expressed to be such Borrower hereunder.

                  (b) No  assurance,  security  or payment  which may be avoided
under any laws relating to  bankruptcy,  insolvency or corporate  reorganization
and no release, settlement or discharge of any of the Subsidiary Borrowers which
may have been  given or made on the  faith of any such  assurance,  security  or
payment,  shall prejudice or affect the right of the Administrative Agent or any
Lender to recover from the Company to the full extent of the undertakings  given
in this Section 10.15 just as if such  release,  settlement or discharge had not
occurred.

                  (c) The  Company  hereby  waives  any rights it may have under
applicable law which may at any time be inconsistent  with any of the provisions
of this  Agreement or which it may have of first  requiring  the  Administrative
Agent or any Lender to proceed against or claim payment from another Borrower or
any  other  party  or  parties.  It is  further  agreed  that  all or any of the
Administrative Agent and the Lenders,  without notice to the Company and without
affecting or impairing the obligations of the Company hereunder, may grant time,
indulgences,  concessions,  releases and discharges to, may take securities from
and give the same, may accept compositions from and may otherwise deal with each
other  Borrower  and all other  parties  as they may see fit and  generally  may
otherwise do or omit to do any act or thing which, but for this provision, might
operate  to affect or impair  the  obligations  of the  Company  hereunder.  The
obligations  of the Company  hereunder  shall not be affected or impaired by any
amendment or modification hereto.

                  (d) The Company hereby waives notice of the acceptance of this
undertaking  and of  presentment,  demand and protest and notices of non-payment
and dishonor and any other demands and notices required by applicable law.

         SECTION  10.16.  Interest  Rate  Limitation.  Notwithstanding  anything
herein to the contrary, if at any time the interest rate applicable to any Loan,
together with all fees,  charges and other amounts which are treated as interest
on such Loan under applicable law (collectively the "Charges"), shall exceed the
maximum lawful rate (the "Maximum Rate") which may be contracted  for,  charged,
taken,  received or reserved by the Lender holding such Loan in accordance  with
applicable law, the rate of interest  payable in respect of such Loan hereunder,
together with all Charges  payable in respect  thereof,  shall be limited to the
Maximum Rate and, to the extent lawful, the interest and Charges that would have
been  payable in  respect  of such Loan but were not  payable as a result of the
operation  of this  Section  shall be  cumulated  and the  interest  and Charges
payable to such Lender in respect of other Loans or periods  shall be  increased
(but not above the Maximum Rate therefor) until such cumulated amount,  together
with  interest  thereon  at the  Federal  Funds  Effective  Rate to the  date of
repayment, shall have been received by such Lender.

         SECTION  10.17.   International   Banking  Facilities.   Each  Borrower
acknowledges  by its  execution  and delivery  hereof (or by its  execution  and
delivery of any applicable  Joinder  Agreement) that (a) it is the policy of the
Board that deposits  received by  international  banking  facilities may be used
only  to  support  the  non-U.S.  operations  of a  depositor  (or  its  foreign
affiliates)  located  outside the United States and that extensions of credit by
international  banking  facilities  may be used  only to  finance  the  non-U.S.
operations of a Borrower (or its foreign  affiliates)  located  outside the U.S.
and (b) funds deposited by any Borrower with an  international  banking facility
of any Lender will be used  solely in support of such  non-U.S.  operations,  or
that of such foreign  affiliates,  and that the proceeds of any Borrowings  from
any such  international  banking  facility  will be used solely to finance  such
non-U.S.  operations, or that of such foreign affiliates. Any terms used in this
Section  10.17 that are not  otherwise  defined  herein,  shall have the meaning
assigned thereto in Regulation D of the Board (as amended from time to time).

         For purposes of the foregoing, (a) if the Ratings established or deemed
to have been established by Moody's,  Duff & Phelps, and S&P for the Rating Debt
shall fall within  different  Levels,  the Applicable Rate shall be based on the
two highest Ratings; provided, that if such two highest Ratings also fall within
different  Levels,  (i) where the split  represents  one subgrade the Applicable
Rate will be  determined  based on the lower of such two Levels;  and (ii) where
the  split  represents  two or  more  subgrades,  the  Applicable  Rate  will be
determined  by reference  to the Level at the midpoint of such highest  ratings;
provided,  that if such midpoint falls between Levels,  the Applicable Rate will
be determined by reference to the Level immediately below such midpoint;  (b) if
the Ratings  established or deemed to have been  established by Moody's,  Duff &
Phelps,  and S&P for the Rating Debt shall be changed (other than as a result of
a change in the rating system of Moody's,  Duff & Phelps,  or S&P),  such change
shall  be  effective  as of the  date on  which  it is  first  announced  by the
applicable Rating Agency;  (c) if Moody's,  Duff & Phelps, or S&P shall not have
in  effect  a  Rating  for  the  Rating  Debt  (other  than  by  reason  of  the
circumstances  referred to in the last  sentence of this  paragraph),  then such
Rating  Agency  shall be  deemed to have  established  a Rating in Level 6. Each
change in the  Applicable  Rate shall apply during the period  commencing on the
effective date of such change and ending on the date  immediately  preceding the
effective date of the next such change. If the rating system of Moody's,  Duff &
Phelps,  or S&P shall change,  or if any such Rating Agency shall cease to be in
the business of rating corporate debt  obligations,  the Company and the Lenders
shall  negotiate in good faith to amend this  definition to reflect such changed
rating  system or the  unavailability  of Ratings  from such Rating  Agency and,
pending the  effectiveness  of any such amendment,  the Applicable Rate shall be
determined  by  reference  to the Rating most  recently in effect  prior to such
change or cessation. Notwithstanding the foregoing, if on the Effective Date, at
least two of the Rating  Agencies  have not  announced a Rating  expressly to be
effective  after the Oryx  Merger,  Level  Three  pricing  shall  apply from the
Effective  Date until at least two of the Rating  Agencies  shall have announced
such Ratings.

                        OPINION OF RUSSELL G. HORNER, JR.



                                                            February 26, 1999



To the Lenders and the Administrative
  Agent Referred to Below
c/o Royal Bank of Canada, as
  Administrative Agent

Dear Sirs:

                  I have acted as counsel for Kerr-McGee Corporation, a Delaware
corporation  (the  "Company")  and each  Subsidiary  Borrower (as defined in the
following  described  Credit  Agreement),  in connection  with the  $500,000,000
3-Year  Revolving  Credit  Agreement  dated as of February 26, 1999 (the "Credit
Agreement"),  among the Company, the Subsidiary  Borrowers,  the banks and other
financial institutions  identified therein as Lenders, and Royal Bank of Canada,
as Administrative  Agent.  Terms defined in the Credit Agreement are used herein
with the same meanings.

                  I have  examined  originals or copies,  certified or otherwise
identified  to  my   satisfaction,   of  such  documents,   corporate   records,
certificates of public  officials and other  instruments and have conducted such
other investigations of fact and law as I have deemed necessary or advisable for
purposes of this opinion.

                  Upon the basis of the foregoing, I am of the opinion that:

                  1. The Company is a  corporation  duly  incorporated,  validly
existing  and in good  standing  under the laws of the State of  Delaware.  Each
Domestic  Subsidiary  Borrower  organized under the laws of the United States of
America,  any State thereof, or the District of Columbia,  is a corporation duly
incorporated,  validly  existing  and in good  standing  (or,  if such  Domestic
Subsidiary  Borrower  is a limited  liability  company,  is a limited  liability
company duly formed,  validly  existing and in good standing)  under the laws of
its  jurisdiction  of  incorporation,  organization  or formation.  Each Foreign
Subsidiary Borrower organized under the laws of a jurisdiction other than United
States of America, any State thereof, or the District of Columbia,  is a company
duly  established  and validly  existing under the laws of its  jurisdiction  of
formation.

                  2.  The  Company  and  each  Subsidiary  Borrower  (a) has all
requisite corporate or limited liability company power and authority to carry on
its  business  as now  conducted,  and (b)  except  where the  failure to do so,
individually or in the aggregate,  could not reasonably be expected to result in
a Material  Adverse  Effect,  is  qualified  to do  business  in, and is in good
standing in, every jurisdiction where such qualification is required.

                  3.  The   Transactions  are  within  the  Company's  and  each
Subsidiary  Borrower's  corporate or limited  liability  company powers and have
been duly authorized by all necessary  corporate or limited  liability  company,
and, if required, stockholder action.
The Credit Agreement has been duly executed and delivered by each Borrower.

                  4. The Transactions (a) do not require any consent or approval
of,  registration  or filing  with,  or any other  action by,  any  Governmental
Authority,  except such as have been  obtained or made and are in full force and
effect,  (b) will not violate any  applicable  law or regulation or the charter,
by-laws  or  other  organizational  documents  of  each  Borrower  or any of its
Subsidiaries or any order of any Governmental Authority, (c) will not violate or
result in a default under any indenture,  agreement or other instrument  binding
upon each Borrower or any of its  Subsidiaries or its assets,  or give rise to a
right  thereunder  to require any payment to be made by a Borrower or any of its
Subsidiaries,  and (d) will not result in the creation or imposition of any Lien
on any asset of the Company or any of its Subsidiaries.

                  5. There are no actions, suits or proceedings by or before any
arbitrator  or  Governmental  Authority  pending  against  or, to my  knowledge,
threatened against or affecting the Company or any of its Subsidiaries (a) as to
which there is a reasonable possibility of an adverse determination and that, if
adversely  determined,  could  reasonably  be expected,  individually  or in the
aggregate,  to have a Material  Adverse  Effect or (b) that  involve  the Credit
Agreement or the Transactions.

                  6. Neither the Company nor any of its  Subsidiaries  is (a) an
"investment  company"  as  defined  in, or  subject  to  regulation  under,  the
Investment  Company  Act of 1940 or (b) a "holding  company"  as defined  in, or
subject to regulation under, the Public Utility Holding Company Act of 1935.

                                     FORM OF
                      OPINION OF SIMPSON THACHER & BARTLETT


                                                          February 26, 1999


Royal    Bank of Canada, as Administrative Agent under the Credit Agreement,  as
         hereinafter defined (the "Agent")

         and

The      Lenders  listed on  Schedule I hereto  which are  parties to the Credit
         Agreement on the date hereof

Ladies and Gentlemen:

         We have acted as counsel to Kerr-McGee  Corporation (the "Company") and
the  subsidiaries  of the Company named on Schedule II attached  hereto (each, a
"Subsidiary Borrower" and, collectively, the "Subsidiary Borrowers"; the Company
and the  Subsidiary  Borrowers  being  referred  to herein  collectively  as the
"Credit Parties") in connection with the preparation,  execution and delivery of
the $500,000,000 3-Year Revolving Credit Agreement dated as of February 26, 1999
(the  "Credit  Agreement")  among the Company,  the  Subsidiary  Borrowers,  the
lending institutions  identified in the Credit Agreement (the "Lenders") and the
Agent. Unless otherwise indicated, capitalized terms used but not defined herein
shall  have the  respective  meanings  set forth in the Credit  Agreement.  This
opinion is furnished to you pursuant to Section 4.01(c) of the Credit Agreement.

         In connection with this opinion, we have examined the Credit Agreement,
signed by each Credit Party thereto and by the Agent and certain of the Lenders.
We also have  examined the  originals,  or  duplicates or certified or conformed
copies,  of such records,  agreements,  instruments and other documents and have
made such other  investigations  as we have deemed  relevant  and  necessary  in
connection with the opinions  expressed herein. As to questions of fact material
to this opinion,  we have relied upon  certificates  of public  officials and of
officers  and  representatives  of the  Credit  Parties.  In  addition,  we have
examined,  and have relied as to matters of fact upon, the representations  made
in the Credit Agreement.
         In  rendering  the  opinions  set  forth  below,  we have  assumed  the
genuineness  of all  signatures,  the legal  capacity  of natural  persons,  the
authenticity  of all documents  submitted to us as originals,  the conformity to
original  documents of all documents  submitted to us as duplicates or certified
or  conformed  copies,  and the  authenticity  of the  originals  of such latter
documents.
         Based  upon  and  subject  to  the   foregoing,   and  subject  to  the
qualifications and limitations set forth herein, we are of the opinion that:
         1. Assuming that proceeds of borrowings will be used in accordance with
the terms of the Credit  Agreement,  the  execution  and  delivery by any Credit
Party of the Credit  Agreement,  its borrowings in accordance  with the terms of
the Credit Agreement and performance of its payment obligations  thereunder will
not result in any  violation of any New York  statute or any rule or  regulation
issued pursuant to any New York statute.

         2. No consent, approval, authorization,  order, filing, registration or
qualification  of or with any New York  governmental  agency is required for the
execution  and  delivery  by any  Credit  Party of the Credit  Agreement  or the
borrowings  by any  Credit  Party in  accordance  with the  terms of the  Credit
Agreement.

         3.  Assuming that the Credit  Agreement is a valid and legally  binding
obligation  of each of the Lenders  party  thereto and assuming that (a) each of
the Credit  Parties is validly  existing and in good standing  under the laws of
the jurisdiction in which it is organized and has duly authorized,  executed and
delivered  the  Credit   Agreement  in  accordance   with  its   Certificate  of
Incorporation  and By-Laws,  (b)  execution,  delivery and  performance  by each
Credit Party of the Credit Agreement do not violate the laws of the jurisdiction
in which it is organized or any other applicable laws (excepting the laws of the
State of New York), (c) execution, delivery and performance by each Credit Party
of the Credit Agreement do not constitute a breach or violation of any agreement
or instrument which is binding upon such Credit Party and (d) no Credit Party is
an "investment  company"  within the meaning of and subject to regulation  under
the Investment  Company Act of 1940, the Credit Agreement  constitutes the valid
and legally binding  obligation of each Credit Party,  enforceable  against such
Credit Party in accordance with its terms.

         Our  opinions  in  paragraph  3 above are subject to (i) the effects of
bankruptcy,  insolvency, fraudulent conveyance,  reorganization,  moratorium and
other similar laws relating to or affecting  creditors' rights  generally,  (ii)
general equitable principles (whether considered in a proceeding in equity or at
law),  (iii) an implied  covenant  of good faith and fair  dealing  and (iv) the
effects  of the  possible  judicial  application  of  foreign  laws  or  foreign
governmental or judicial action affecting creditors' rights.
         We note that (A) a New York  statute  provides  that with  respect to a
foreign  currency  obligation  a court of the State of New York  shall  render a
judgment or decree in such foreign currency and such judgment or decree shall be
converted into currency of the United States at the rate of exchange  prevailing
on the  date of entry of such  judgment  or  decree  and (B) with  respect  to a
foreign currency  obligation a United States Federal court in New York may award
judgment in United States dollars, provided that we express no opinion as to the
rate of exchange such court would apply.
         We express no opinion with respect to:
         (A) the  effect  of any  provision  of the  Credit  Agreement  which is
intended to permit modification  thereof only by means of an agreement signed in
writing by the parties thereto;
         (B) the effect of any provision of the Credit  Agreement  insofar as it
provides  that any  Person  purchasing  a  participation  from a Lender or other
Person may exercise set-off or similar rights with respect to such participation
or that any Lender or other Person may exercise  set-off or similar rights other
than in accordance with applicable law;
         (C) the  effect  of any  provision  of the  Credit  Agreement  imposing
penalties or forfeitures;
         (D) the  enforceability of any provision of the Credit Agreement to the
extent that such  provision  constitutes  a waiver of illegality as a defense to
performance  of contract  obligations;  (E) the effect of any  provision  of the
Credit Agreement  relating to  indemnification or exculpation in connection with
violations of any securities laws or relating to  indemnification,  contribution
or  exculpation in connection  with willful,  reckless or criminal acts or gross
negligence  of the  indemnified  or  exculpated  Person or the Person  receiving
contribution.; and

         (F) the effect of any  provision  of the Credit  Agreement  whereby the
Credit Parties submit to the  jurisdiction  of the United States  District Court
for the Southern  District of New York or the Supreme  Court of the State of New
York.
         We are  members  of the Bar of the  State  of New  York,  and we do not
express any opinion herein concerning any law other than the law of the State of
New York.
         This  opinion  letter is rendered to you in  connection  with the above
described  transactions.  This opinion  letter may not be relied upon by you for
any other  purpose,  or relied  upon by any other  person,  firm or  corporation
without our prior written consent.

                                                     Very truly yours,

         THIS CASH COLLATERAL  ACCOUNT AGREEMENT (this  "Agreement") is made and
entered  into as of the __ day of _______,  ____,  [between][among]  [KERR-McGEE
CORPORATION, a Delaware corporation (the "Company"), [______________________,  a
____________________   ("  "),]]  and  ROYAL   BANK  OF   CANADA   ("RBC"),   as
administrative agent (in such capacity,  the "Administrative  Agent") for itself
and the Lenders (as defined in the Credit Agreement referred to below).

                                                      RECITALS

         A. On February 26, 1999,  the Company,  the  Subsidiary  Borrowers  (as
defined in the  Credit  Agreement),  the  Administrative  Agent and the  Lenders
executed that certain  Revolving Credit Agreement (as amended from time to time,
the "Credit Agreement")  whereby,  upon the terms and conditions stated therein,
the Lenders agreed to make Loans (as defined in the Credit Agreement) (a) to the
Company  and  the  Domestic  Subsidiary  Borrowers  (as  defined  in the  Credit
Agreement) or any one or more of them, up to the Domestic  Available  Amount (as
defined in the Credit Agreement) and (b) to the Foreign Subsidiary Borrowers (as
defined in the Credit  Agreement)  or any one or more of them up to the  Foreign
Available Amount (as defined in the Credit Agreement).

         B. Section 2.09(c) of the Credit  Agreement  provides that in the event
that (i) the aggregate principal amount of all Loans made to the Company and the
Domestic Subsidiary  Borrowers exceeds the Domestic Available Amount or (ii) the
aggregate  amount of all Loans made to the Company  and the  Foreign  Subsidiary
Borrowers exceeds the Foreign  Available Amount,  the Company may, and may cause
one of more of the  Subsidiary  Borrowers  to, in lieu of prepaying  such excess
described  in clause (i) or (ii) above,  provide  cash  collateral  equal to the
amount of such  excess  plus any accrued  and unpaid  interest  thereon,  to the
Administrative  Agent for the benefit of the  Lenders  pursuant to the terms and
conditions of this Agreement.

         C.  Therefore,  in accordance  with the terms of Section 2.09(c) of the
Credit Agreement, and for other good and valuable consideration, the receipt and
sufficiency  of which are hereby  acknowledged,  [the  Company  and  [Subsidiary
Borrower]] hereby [agrees][agree] and with the Administrative Agent as follows:

                                    AGREEMENT

         Section  (1)  Pursuant  to Section  2.09(c)  of the  Credit  Agreement,
simultaneously   with  the  execution  of  this  Agreement,   [the  Company  and
[Subsidiary Borrower]] will make [a deposit][deposits] in an amount equal to the
excess as  determined  in accordance  with Section  2.09(c)[(ii)][(iii)]  of the
Credit  Agreement  plus all  accrued  and  unpaid  interest  thereon  (the "Cash
Collateral")  in an account with the  Administrative  Agent,  in the name of the
Administrative  Agent and for the benefit of the Lenders styled "Kerr-McGee Cash
Collateral  Account,"  which is an interest  bearing  collateral  account and is
subject to the exclusive dominion and control,  including the exclusive right of
withdrawal, of the Administrative Agent (the "Cash Collateral Account").

         Section   (2)  [The   Company   and   [Subsidiary   Borrower]]   hereby
[pledge][pledges]  and  [grant][grants]  to the  Administrative  Agent  for  the
account of the Lenders a security  interest in the Cash  Collateral and the Cash
Collateral  Account to secure the payment and  performance of the obligations of
the Company and the Subsidiary Borrowers under the Credit Agreement.



         Section (3)

                  (a) The Cash Collateral may be invested by the  Administrative
         Agent at the option and sole discretion of the Administrative Agent and
         at the risk and  expense of [the  Company and  [Subsidiary  Borrower]].
         Interest or profits,  in any, on such  investments  shall accumulate in
         the  Cash  Collateral  Account.  Other  than  interest  earned  on such
         investments, the Cash Collateral shall not bear interest. Moneys in the
         Cash Collateral Account shall be applied by the Administrative Agent to
         satisfy the  obligations  of the Company and the  Subsidiary  Borrowers
         under the Credit Agreement.

                  (b) Moneys in the Cash Collateral Account shall be returned to
         [the Company and  [Subsidiary  Borrower]]  within three  Business  Days
         after the  earlier  to occur of (i) the first  Business  Day of a month
         that the Administrative Agent determines that the Cash Collateral is no
         longer required pursuant to Section  2.09(c)[(ii)][(iii)] of the Credit
         Agreement  and (ii) a prepayment of the Loans in an amount equal to the
         Cash Collateral.  In such event, the Administrative  Agent will execute
         and deliver to [the Company and  [Subsidiary  Borrower]] an appropriate
         release  of the  pledge,  liens,  security  interests  and  obligations
         created  hereby  and  will  release  to [the  Company  and  [Subsidiary
         Borrower]] all funds then remaining in the Cash Collateral Account.

         Section (4) [THE COMPANY AND [SUBSIDIARY BORROWER]]  [AGREES][AGREE] TO
REIMBURSE  AND  INDEMNIFY  THE  ADMINISTRATIVE  AGENT  FOR AND HOLD IT  HARMLESS
AGAINST  ANY  LOSS,  LIABILITY,  CLAIM,  DEMAND,  CAUSE OF  ACTION,  DAMAGES  OR
CONTROVERSY AT ANY TIME ARISING OUT OF OR IN CONNECTION WITH  PERFORMANCE BY THE
ADMINISTRATIVE  AGENT OF ANY OF ITS DUTIES AND OBLIGATIONS UNDER THIS AGREEMENT,
AS WELL AS ALL COSTS AND  EXPENSES,  INCLUDING  BUT NOT  LIMITED  TO  REASONABLE
ATTORNEYS' FEES, INCURRED IN THE ADMINISTRATION OR PREPARATION OF THIS AGREEMENT
OR IN  DEFENDING  AGAINST ANY CLAIM OR  LIABILITY  ARISING OUT OF OR RELATING TO
THIS AGREEMENT OTHER THAN ARISING OUT OF OR RELATING TO THE WILFUL MISCONDUCT OR
GROSS NEGLIGENCE OF THE ADMINISTRATIVE AGENT.

         Section (5) [The Company and  [Subsidiary  Borrower]]  will promptly at
[its][their] sole expense, upon reasonable request, execute and deliver all such
other   documents  in  form  and  substance   reasonably   satisfactory  to  the
Administrative  Agent and its legal counsel and take such other action as may be
reasonable  and  necessary  to fully  effectuate  the terms  and  intent of this
Agreement.

         Section 7. In the event that one or more of the provisions contained in
this Agreement shall, for any reason, be held invalid,  illegal or unenforceable
in any respect (i) [the Company and [Subsidiary Borrower]]  [agrees][agree] that
such  invalidity,  illegality  or  unenforceability  shall not  affect any other
provision of this Agreement,  and (ii) [the Company,] [ Subsidiary Borrower] and
Administrative  Agent  (acting on behalf of and at the direction of the Lenders)
will  negotiate in good faith to amend such  provision so as to be legal,  valid
and enforceable.

         Section 8. This Agreement may be executed in counterparts, and it shall
not be necessary  that the  signatures of all parties hereto be contained on any
one counterpart hereof; each counterpart shall be deemed an original, but all of
which together shall constitute one and the same instrument.

                              AUDITOR'S CERTIFICATE



To Kerr-McGee Corporation:

         We  have  examined  the   consolidated   balance  sheet  of  Kerr-McGee
Corporation (a Delaware corporation) and subsidiary companies as of December 31,
____ and ____,  and the  related  consolidated  statements  of income,  retained
earnings and cash flows for each of the three years in the period ended December
31,  ____ and have  issued our report  thereon  dated  February  __,  ____.  Our
examination was made in accordance with generally  accepted  auditing  standards
and,  accordingly,  included such tests of the accounting records and such other
auditing procedures as we considered necessary in the circumstances.

         We have read the Credit  Agreement  dated as of February 26, 1999 among
Kerr-McGee  Corporation (the  "Company"),  the lenders parties thereto and Royal
Bank of Canada, as Administrative Agent (as amended, modified,  supplemented and
restated from time to time, the "Credit Agreement"), particularly Articles V, VI
and VII.  These  articles  contain  certain  covenants  of the  Company  and the
Subsidiary  Borrowers  relative to certain  financial  conditions  and  describe
Events of Default relative to such covenants. We have also read the accompanying
officer's  certificate  prepared by your chief accounting  officer  described in
Section 5.01(c) of the Credit Agreement.

         In connection with our examination,  nothing came to our attention that
caused us to believe  that you were in  default  with any of the  provisions  of
Article  VII of the  Credit  Agreement  insofar as they  pertain  to  accounting

Management's Discussion and Analysis

Transactions in 1998

     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.
The  sales  were  completed  in July 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  production  capacity was  significantly  expanded
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. This
acquisition increased annual production capacity by approximately 55%.
     Oil and gas production and exploratory prospects expanded with the purchase
of the North Sea assets of Gulf Canada Resources  Limited (Gulf Canada) for $422
million.  This transaction was effective March 31, 1998. The company's North Sea
production  and reserves were increased by 80% and 47%,  respectively,  compared
with year-end 1997.
     The merger with Oryx Energy  Company  (Oryx) was announced in October 1998.
As a  result  of the  merger  Kerr-McGee  is,  based  on  proven  reserves,  the
fourth-largest among the independent, non-integrated oil and gas exploration and
production companies base d in the United States.

Kerr-McGee/Oryx

     On February 26, 1999, the merger between  Kerr-McGee and Oryx was completed
(see Note 23). Oryx's operations have been merged into and will be reported with
the company's exploration and production segment.
     Under the merger agreement, each outstanding share of Oryx common stock was
exchanged   for  0.369  shares  of  newly  issued   Kerr-McGee   common   stock.
Approximately  39 million  shares of  Kerr-McGee  stock were  issued to the Oryx
shareholders,  bringing  total shares  outstanding  at February 26, 1999,  to 86
million.  The existing  Oryx debt ($1.3 billion at December 31, 1998) has become
the company's  obligation.  The Oryx 7-1/2% convertible  debentures due 2014 are
convertible into shares of Kerr-McGee common stock at a conversion rate adjusted
to reflect the exchange ratio.
     The merger is being accounted for using the pooling of interests  method of
accounting.  Therefore,  all  prior  period  results  of  operations,  financial
position  and cash flows will be  restated to reflect  the  combined  company as
though it had always been in  existence.  These  results  will be presented in a
Form 8-K to be filed with the Securities and Exchange Commission in mid-1999.
     The financial  statements  and related notes included in this Annual Report
to Stockholders  and this  Management's  Discussion and Analysis pertain only to
the operations of Kerr-McGee Corporation as it existed at December 31, 1998, and
therefore do not reflect the results of operations,  financial  position or cash
flows of Oryx.

Operating Environment and Outlook
  
     The merger with Oryx  creates a much larger  global oil and gas reserve and
production  base.  The company's  management  expects the benefits of the pretax
synergies of the two organizations to be $100 million annually.
     Oil prices in early 1999 are at their  lowest  level since 1985.  The Asian
and South  American  economic  downturns  have reduced  demand,  and prices have
remained low for approximately 18 months.  These low oil prices have forced most
exploration  and  production  companies  to reduce  capital  budgets.  Crude oil
inventories  declined in early 1999,  which indicates that world oil consumption
is higher than production.  Management  recognizes that supply restraint by OPEC
and a few larger non-OPEC  producers  remains a risk to commodity  pricing,  but
believes  prices will rise because of the high levels of internal  political and
economic  risk in major  producing  nations,  increasing  demand  and the likely
reduction of crude oil stocks.
     In early 1999, gas markets in the United States have seen 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 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  should  contribute to higher prices later in 1999 and
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 certai n international  markets.  Demand in early 1999 is about 90% of
industry capacity. 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.

Results of Consolidated Operations

     Net income and per-share  amounts for each of the three years in the period
ended December 31, 1998, were as follows:

     Net income 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 an additional $14 million. In
1997, special items were also principally  nonoperating and increased net income
by $10 million. The 1996 special items resulted in a charge to net income of $10
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 from continuing  operations  excluding
special items to net income.

     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.
     Income from continuing operations excluding special items for 1998 declined
$114 million from 1997.  This primarily  resulted from a $165 million decline in
exploration and production  operating profit excluding special items,  which was
partially off set by a $31 million increase in chemical results. In 1997, income
from continuing  operations  excluding  special items decreased $23 million from
the prior year,  due  primarily  to declines of 25% and 7% in  operating  profit
excluding   special  items  of   exploration   and   production   and  chemical,
respectively. The merger 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 the related results are not
included in  operating  profit in 1998 and 1997 (see Note 4).  Operating  profit
excluding  special  items was $128  million,  $262  million and $326 million for
1998, 1997 and 1996, respectively.
     Sales from  continuing  operations were $1.4 billion in both 1998 and 1997,
compared  with $1.6 billion in 1996.  Declines in 1998 average  sales prices for
oil and natural gas of 36% and 15%,  respectively,  were offset by sales  volume
increases in crude oil, natural gas and titanium dioxide pigment and sales price
increases for pigment.  The volume  increases in crude oil and natural gas sales
were  primarily  a result of the  company's  purchase of the North Sea assets of
Gulf Canada.  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 the 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 $818  million,  $739  million and $804
million 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 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 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 work  process  review and  organizational
restructuring of several groups, the 1996-1997 relocation of the exploration and
production unit to Houston, Texas, and severance associated with the divestiture
program and the Devon merger.
     Asset impairment  totaled $370 million in 1998 and $25 million in 1996 (see
Note 10). Of the 1998 amount,  $313 million was for writedowns  associated  with
certain  oil and gas  fields  located  in the North  Sea,  China and the Gulf of
Mexico. 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 $84 million, $65 million and
$74 million,  respectively.  The 1998 increase was the result of higher dry hole
costs  in  the  Gulf  of  Mexico  and  Thailand,  higher  undeveloped  leasehold
amortization in the Gulf of Mexico and higher district  expense in China and the
North  Sea,  partially  offset  by lower  dry hole  costs  in  China  and  lower
geological  expenses.  Lower dry hole costs in the North Sea,  offset in part by
higher costs in China,  were the primary reason for the reduced 1997 costs. Also
contributing  to  the  reduction  was  lower  undeveloped  lease   amortization,
partially offset by higher geophysical cost.
     Interest and debt expense  totaled $58 million in 1998, $47 million in 1997
and $52 million in 1996. Borrowings increased in 1998 due to the acquisitions of
European  chemical  operations and North Sea oil and gas 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 were $23 million and contributed to higher
other income, as compared with 1996.

     Asset impairment for certain oil and gas fields in the North Sea, China and
Gulf of Mexico  totaled $313 million in 1998 and is reflected in special  items.
Special items in 1997  consisted  primarily of  additional  costs for the unit'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 the North American onshore properties into Devon and the
announcement of the relocation of certain  exploration and production  personnel
to Houston, Texas.
     Increases in 1998 production volumes of both oil and gas did not offset the
large price declines. As a result,  operating profit excluding special items was
negatively impacted by approximately $100 million. The volume increase primarily
resulted  from the  acquisition  of  additional  North Sea assets.  In addition,
exploration  expenses increased and contributed to the 1998 decline in operating
profit from 1997. The primary reasons for lower 1997 operating  profit excluding
special  items,  compared  with  1996,  were  equity  accounting  for the merged
properties  and lower  average sales prices for crude oil,  partially  offset by
increased sales prices for natural gas and lower exploration expenses.

     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  and in  1996  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  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 mill ion 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 $99 million in 1998, compared
with $569 million in 1997 and $645 million in 1996.
     The decrease in 1998  resulted  primarily  from  working  capital and other
changes that used cash from operating activities and lower net operating income.
Net cash  provided  by  operating  activities  was reduced by taxes paid of $115
million related to the sale of the discontinued coal operations.
     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,
partially  offset by working  capital and other changes that  increased net cash
provided by operating activities.  Cash flow provided by operating activities in
1997 was also adversely  affected by the company's  merger of its North American
onshore oil and gas properties  into Devon,  since  undistributed  earnings from
equity  affiliates  represent a noncash item. The net cash provided by operating
activities  in 1996 was  primarily  attributable  to the  company's  record  net
income.
     In 1998, approximately $600 million in cash was provided from proceeds from
the sales of the company's  discontinued  coal operations,  $39 million from the
sale of the ammonium perchlorate operations and $21 million from other investing
activities.  These sources of cash from  investing  activities  and net proceeds
from debt issuances of $362 million were used for capital  expenditures  of $550
million and  acquisitions  of $518  million for the Gulf Canada North Sea assets
and the European titanium dioxide pig ment facilities.
     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 13). In 1997,  cash available
increased $21 million from the sale of equity  securities,  $18 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 $48 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 $25 million  (580,000  shares) was purchased before the program
was cancelled because of the company's merger with Oryx. 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
     The company's  balance sheet reflects a solid working capital  position and
low debt to capitalization.  The company's debt has been rated "A", "A3" or "A-"
by various rating agencies,  resulting in low debt costs. In connection with the
merger with Oryx, the rating  agencies have reviewed the company's debt ratings.
The company has been notified that the new ratings are "BBB+",  "Baa1" and "BBB"
for its senior  unsecured debt.  This reflects the substantial  increase in debt
leverage  because of the  assumption of Oryx debt  obligations.  At December 31,
1998, the company's net working capital  position was $215 million,  an increase
of $49 million from the prior year.  The  strengthening  of the working  capital
position was directly  attributable  to increases in  receivables  and inventory
generated by the company's  European  pigment  operations  since  acquisition in
March 1998. The 1997 net working  capital  position was $166 million,  a decline
from the 1996  year-end  position.  The merger of the company's  North  American
onshore exploration and production  properties  contributed to the lower working
capital  position,  since certain  components of working  capital were converted
into the Devon equity investment.
     At year-end 1998, total debt  outstanding was $944 million.  The percentage
of total debt to total  capitalization  was 41% at  December  31,  1998;  29% at
December 31, 1997; and 33% at year-end  1996. The higher  percentage at year-end
1998  resulted  from the increase in borrowings  due to the  acquisition  of the
North Sea assets and 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.
     The company last issued publicly held debt in October 1997. The majority of
the then  outstanding  floating-rate  debt was  replaced  with $300  million  of
fixed-rate securities - $150 million of 7.125% debentures (effective rate 7.01%)
due October 15, 2027,  and $150 million of 6.625% notes  (effective  rate 6.54%)
due October 15, 2007.
     Additionally,  the company and/or its subsidiaries  have several  revolving
credit  agreements.  At year-end 1998,  $281 million was  outstanding  under the
agreements  with interest  payable at varying  rates.  At December 31, 1998, the
company  had unused  lines of credit and  revolving  credit  facilities  of $525
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.
     In 1998, 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) and is renewable annually.  At December 31, 1998, an amount equal to $8
million was outstanding under this arrangement. Subsequent to year-end 1998, the
company and  Kerr-McGee  Oil (U.K.) PLC  notified the lead bank of the intent to
eliminate a $75 million  credit  facility.  On February  26,  1999,  the company
signed two new revolving credit agreements, a 3-year $500 million facility and a
364-day $250 million facility. Initially, one-third of the borrowings under each
of these agreements can be made in British pounds sterling, euros or other local
European Union currencies.  Interest for each of the revolving credit agreements
is payable at varying rates.
     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 $550 million in
1998,  $341 million in 1997 and $392  million in 1996, a total of $1.3  billion.
During this same  period,  $1.6  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 period by approximately  $20
million.
     Management  anticipates  that 1999  cash  capital  requirements,  currently
estimated  at  $545  million  after  the  merger  with  Oryx,  and  the  capital
expenditures  programs  for the next  several  years can continue to be provided
through  internally  generated funds and selective  short-term  and/or long-term
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 15 to the  Consolidated  Financial  Statements  for
additional  discussion  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 pounds 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.
     At year-end 1998 and 1997, the company's derivative  financial  instruments
were comprised only of foreign  currency  forward  contracts.  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.

     At December 31,  1997,  long-term  debt  included  fixed-rate  debt of $517

7.25% and $37 million  variable-rate debt, which approximated fair value, with a
weighted-average interest rate of 6.04%.

Commodity Prices
     Although no such  contracts  were  entered  into  during 1998 or 1997,  the
company has periodically  used 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  qualified as
hedges and correlated to price  movements of crude oil and natural gas, any gain
or loss from these  contracts was explicitly  deferred and recognized as part of
the hedged transaction.

Environmental Matters

     The  company's  operations  are subject to various  environmental  laws and
regulations. Under these laws, the company is subject to possible obligations 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 the remediation of
13 existing  EPA  Superfund  sites 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  si tes.  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, $88 million was added
to the  reserve  for active and  inactive  sites.  At  December  31,  1998,  the
company's reserve for these sites totaled $226 million. In addition, at year-end
1998,  the  company  had a reserve of $73  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, $216 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:

estimated  costs  of  investigation  and/or  remediation  that is  probable  and

it had some ongoing financial involvement in investigation and/or remediation at

     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  in both  information  technology  and
non-information  technology  systems.  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  and  evaluation  of  systems  that  need  to  be modified or
    replaced.
  - Remediation work to modify existing systems or install new systems.
  - Testing and validation of systems and applications.

     An integral  part of the  Program is  communication  with third  parties to
assess the 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  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 which  include  manual
systems and other procedures to accommodate  significant  disruptions that could
be caused by system  failures.  When possible,  alternative  providers are being
identified in the event that certain critical suppliers are unable to provide an
acceptable level of service to the company.
     At December 31, 1998, approximately 99% of the planned work on the business
systems had been  completed,  with all phases  completed in the first quarter of
1999.  Most of these  projects  were  system  replacements  to improve  business
functionality  and were not  undertaken  solely  because  of Year  2000  issues.
Approximately  70%  of  the  planned  work  on  facilities  integrity  was  also
completed. These activities are expected to be completed by the third quarter of
1999.   Ongoing  work  in  the  areas  of  contingency   planning,   third-party
communications  and Year 2000 response team training is expected through the end
of 1999.
     Inception-to-date  Program  expenditures  totaled  $42  million at year-end
1998,  which  includes  $16 million  spent during  1998.  The total  capital and
operating  costs to achieve Year 2000  readiness are estimated to be $45 million
over  the  period  of the  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
short-term and/or long-term borrowings.
     The merger with Oryx was  completed in the first  quarter of 1999,  and the
Year 2000 programs of the companies were combined.  Approximately  75% of Oryx's
business  systems  will be  replaced  with  Kerr-McGee's  Year  200  0-compliant
systems.  The  remaining  business  systems  will be  modified  to be Year  2000
compliant by the third quarter of 1999. The status of the  facilities  integrity
is being assessed and will be included in the company's Program.  Therefore, the
cost  and  progress  of the  Kerr-McGee  Program  will be  impacted  and  future
disclosures adjusted appropriately.
     The  failure  to  correct a  material  Year 2000  problem  could  result in
disruption  to 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 readiness,  there can be no assurance
that all  entities  with  which  the  company  does  business  will be Year 2000
compliant.  Contingency  plans are being  developed to address  these  concerns.
However,  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.  This would
most likely  result from failure of critical  operating or safety  components or
the failure of a key third-party supplier or customer.

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 will be adopted for the
first quarter of 1999, and the company will recognize  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.
The company is currently  evaluating the impact the standard will have on income
from continuing operations;  however,  management believes it will be immaterial
due to the limited amount of hedging activity in which the company 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.
     Certain  information in the Year 2000 Readiness section is forward looking.
The Year 2000  Program  and the date 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 im plementation 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 inte rnal 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 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 provide a reasonable basis for our opinion.
     In our opinion,  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.

Notes to Financial Statements

1. Significant Accounting Policies

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 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 $9 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).

Net Income (Loss) per Common Share
     Basic net income 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 outstanding
for the period and common stock equivalents.
     The weighted-average  number of shares used to compute basic net income per
share was 47,504,409 in 1998;  47,807,916 in 1997 and 49,419,993 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 48,000,082 in 1997 and 49,657,890 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  157,000  and  153,000  employee  stock  options  outstanding  at
year-end 1997 and 1996, respectively.  The inclusion of these options would have
been  anti-dilutive  since  they  were  not  "in  the  money"  at the end of the
respective years.

Cash Equivalents
     The company  considers all  investments  purchased with a maturity of three
months or less to be cash equivalents.  Cash equivalents totaling $57 million in
1998 and $132 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 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 $12 million,  $8 million and $9 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.  Net lease rental expense was $19 million in 1998,
$14 million in 1997 and $13 million in 1996.
     The aggregate minimum annual rentals under  noncancelable  leases in effect
on December 31, 1998, totaled $72 million,  of which $13 million is due in 1999,
$12 million in 2000, $27 million in the period 2001 through 2003 and $20 million
thereafter.

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

Site Dismantlement, Reclamation and Remediation Costs
     The  company  provides  for the  estimated  cost 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 Plans
     The  company  accounts  for its  employee  stock  option  plans  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 requireme nts 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.

     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  in  certain  North  Sea oil and gas  properties;  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 15 and 19.
     Effective  December 31, 1996, the company merged its North American onshore
exploration and production  properties 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.

     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 year-end
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

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 $525 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
of $8 million (3.63% average interest rate).  Outstanding at year-end 1997 was a
note payable of $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 $37 million, respectively, was classified as long-term
consistent with this policy.
     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 U.S. 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 January 31, 1999, Chemical has been
reimbursed approximately $54 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
$226 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 $540 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 in the North Sea,  China and
the Gulf of Mexico 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 per  barrel  for  1999,
increasing  $1 per  barrel  each year up to $20 per  barrel.  Natural  gas price
estimates were $2.25 per MMBtu for 1999,  increasing $.10 per MMBtu each year up
to $2.45 per MMBtu.  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 16% 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.

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  the 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.
     Following  are the sales and pretax  income  included  in the  Consolidated
Statement  of Income in each of the last three  years for assets sold during the
three-year  period ended December 31, 1998.  Any impairment  loss is included in
the pretax income amounts.  The company had no material assets held for disposal
at year-end 1998.

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 is composed of the following:

     The corporate tax rate in the United  Kingdom will decrease 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 decrea sed the international deferred provision for income taxes by
$8 million in both 1998 and 1997. The 1998,  1997 and 1996  provision  (benefit)

     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

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

14. Other Income

     Other  income is as  follows  during  each of the  years in the  three-year

15. 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:

                                                    1998              1997
                                             Carrying   Fair  Carrying    Fair
(Millions of dollars)                          Amount  Value    Amount   Value
- ------------------------------------------------------------------------------
Cash and cash equivalents                       $114    $114      $183    $183
Long-term notes receivable                         3       3         5       5
Contracts to sell foreign currencies              --       2        --       8
Contracts to purchase foreign currencies          --      70        --     102
Short-term borrowings                             36      36        25      25
Total long-term debt                             908   1,017       554     669

     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
chemicals'  accounts  receivable  generated from titanium  dioxide pigment sales
denominated  in foreign  currencies  ($30 million hedged in 1998 and $65 million
hedged  in  1997)  and  the  operating   costs  and  capital   expenditures   of
international  chemical  operations  ($53 million hedged in 1998 and $50 million
hedged in 1997). 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
  - 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 8 million  British  pounds  sterling
    for $12 million
  - Contracts  maturing  January  through  April  1998  to  sell various foreign
    currencies (principally European) for $8 million

     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 1996,  the company sold forward 10 million  barrels of crude oil and
37 billion cubic feet of natural gas representing  approximately  40% and 36% of
its worldwide  crude oil and natural gas production,  respectively.  Net hedging
losses  recognized in 1996 totaled $37 million.  The effect of the losses was to
reduce the company's  1996 average gross margin for crude oil and natural gas by
$1.04 per barrel and $.11 per MCF, respectively. There were no open crude oil or
natural gas  contracts  at year-end  1996,  and no  contracts  were entered into
during 1998 or 1997.
     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 may at
times 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.

16. Taxes, Other than Income Taxes

     Taxes,  other than income taxes, as shown in the Consolidated  Statement of
Income for the years ended December 31, 1998, 1997 and 1996, are composed of the
following:

(Millions of dollars)                           1998  1997  1996

17. 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.
     Transactions  during the past three years under these employee stock option
plans are summarized below:

     Financial  Accounting  Standards Board Statement (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," under which 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  estimated  weighted-average  fair  value at the grant  date would have been
$11.20, $14.37 and $13.17 per option for those options granted in 1998, 1997 and
1996,  respectively,  and 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.

18. Restructuring Charges        

     The company  completed a work process  review  during 1998 that resulted in
the elimination of nonessential work processes, organizational restructuring and
employee  reductions  in both the  operating  and staff units.  As a result,  75
employees  were notified that their  positions  would be  eliminated.  Most were
terminated during 1998.
     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 its
North American  onshore  properties into Devon and the relocation of the unit to
Houston,  Texas.  This program was  essentially  completed at year-end  1997 and
resulted in approximately 300 employees terminating their employment.
     During the three-year period ended December 31, 1998, the company accrued a
total of $19 million for the cost of termination benefits for retiring employees
to be paid from retirement plan assets, future compensation,  relocation,  lease
cancellation  and  outplacement.  The $2 million  reserve at December  31, 1998,
primarily  represents  remaining  severance costs, which are expected to be paid
and charged to the reserve during 1999. The accruals,  expenditures  and reserve
balances are set forth below:

19. 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  these 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.
     At  December  31,  1998 and  1997,  the ESOP  trust  held  shares  of stock
allocated to participants' accounts and in the loan suspense account as follows:

(Thousands of shares)                               1998      1997
- ------------------------------------------------------------------
Participants' accounts                             1,196     1,343
Loan suspense account                                934     1,110

     The shares  allocated  to  participants  at  December  31,  1998,  included
approximately  45,000 shares released in January 1999, and at December 31, 1997,
included approximately 15,000 shares released in January 1998.
     All  ESOP  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-related  expense of $11 million,  $10 million and $12 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 $2 million, $1 million and $9 million to the ESOP
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.

20. 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:

</TABLE>

     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 $18 million and $14 million at December
31, 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%     7.0%     7.5%
Expected return on plan assets              9.00      9.0      9.0
Rate of compensation increases              5.00      5.0      5.0

     The  health  care cost  trend  rate used to  determine  the  year-end  1998
postretirement benefit obligation was 7.5% in 1999, gradually declining to 5% in
the year 2009 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 $13 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 $11 million.  It was not
practical  to  calculate  the  effect on net  periodic  expense  of the  percent
decrease in the health care cost trend rate.

21. 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 explores for,  develops and produces oil and gas
in the Gulf of Mexico, United Kingdom sector of the North Sea, Indonesia, China,
Yemen,  Thailand  and  Gabon.  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.
     Crude  oil  sales to an  individually  significant  customer  totaled  $156
million  and $202  million  for  1997  and  1996,  respectively.  There  were no
individually  significant  customers in 1998. Sales to subsidiary  companies are
eliminated as described in Note 1.

23. Merger with Oryx Energy Company (Unaudited)

     On February 26, 1999,  the company  completed the merger with Oryx upon the
approval  of the  shareholders  of each  company.  Under the terms of the merger
agreement,  each outstanding  share of Oryx common stock was exchanged for 0.369
shares of newly issued  company  stock.  Approximately  39 million shares of the
company  stock were issued to the Oryx  shareholders,  bringing the total shares
outstanding  to  approximately  86 million.  The merger  qualifies as a tax-free
exchange  to Oryx  shareholders  and has  been  accounted  for as a  pooling  of
interests.  Presented below are combined condensed financial  statements for the
year ended and at December 31, 1998, as though the merger had been  completed at
year-end.

     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 is $221
million  that  represents  the  company's  proportional  interest  in an  equity
affiliate's net  capitalized  costs at both 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.

26. 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
on 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.

27. 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 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.

29. 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.
