                               Joint News Release

Kerr-McGee Corporation                            Westport Resources Corporation

           Kerr-McGee and Westport Announce $3.4 Billion Stock Merger
           ----------------------------------------------------------

     Oklahoma City and Denver,  April 7, 2004 - Kerr-McGee Corp. (NYSE: KMG) and
Westport  Resources  Corp.  (NYSE:  WRC) today  announced  that their  boards of
directors have  unanimously  approved a strategic merger valued at approximately
$3.4 billion.  The merged  company will be known as Kerr-McGee  Corporation  and
will be headquartered in Oklahoma City.

Strategic Benefits
------------------
o    Complementary  high-quality  assets in core U.S. Onshore and Gulf of Mexico
     regions

o    Enhances stable base of high-margin production

o    Expands low-risk exploitation opportunities

o    Increases free cash flow for high-impact exploration opportunities

o    Generates cost savings / synergies in excess of $40 million pretax annually

o    Reduces financial leverage and enables greater financial flexibility

o    Accretive to earnings and cash flow in 2005 and thereafter

     "Westport's extensive inventory of low-risk U.S. exploitation opportunities
complements  Kerr-McGee's high-impact deepwater exploration program providing us
a more  predictable  performance  profile,"  said  Luke R.  Corbett,  Kerr-McGee
chairman and chief executive officer.  "Westport's  substantial property base in
the  Rockies  expands  our  platform  for  applying  our  proven  tight-gas  and
supply-chain  expertise.  These new  properties  have a  probable  and  possible
resource  potential of 1.8 trillion cubic feet of natural gas equivalent (TCFe),
and more than 2,500 low-risk  drilling  locations have already been  identified.
When combined with our existing U.S. onshore property position, these properties
will provide a stable  foundation of high-margin  production and low-risk growth
opportunities. Additionally, the incremental free cash flow generated from these
properties  will give Kerr-McGee  added financial  flexibility to accelerate our
high-potential deepwater program."
     "This transaction  provides important  benefits to our shareholders,"  said
Don  Wolf,   Westport  chairman  and  chief  executive  officer.   "It  provides
significant value while retaining the opportunity to participate in the exciting
upside potential of Kerr-McGee. Our shareholders will benefit from becoming part
of a larger,  more  diversified  company with  tremendous  growth  opportunities
balanced with a substantial development portfolio and a strong balance sheet."

Combined Company
----------------
o    Proved  reserves of  approximately  1.3 billion barrels of oil equivalent -
     57% natural gas and 76% located in the U.S.

o    High-margin  production of approximately  1.2 billion cubic feet of natural
     gas and 160,000 barrels of oil per day

o    High-potential   exploratory  program  with  more  than  71  million  gross
     undeveloped acres worldwide

o    Titanium  dioxide  production  capacity of 668,000 tonnes per year, gross -
     76% from proprietary chloride technology

o    Net debt as a  percent  of total  capitalization  of  approximately  42% by
     year-end

     The addition of  Westport's  reserves  will  increase  Kerr-McGee's  proved
reserves by nearly 30%,  mainly from North American  natural gas. As of December
31, 2003,  Westport had 1.8 TCFe of proved  reserves  which were 76% natural gas
and  primarily  located  in the Rocky  Mountain  and  Texas  Gulf  Coast  areas.
Third-party reserve consultants determined 87% of the proved reserves.  Westport
has an  additional  1.8 TCFe of  identified  probable  and  possible  resources.
Approximately  50% of these  resources  are  located in and  around the  Natural
Buttes field,  in the Uinta basin in northeast  Utah. The Greater Natural Buttes
area is similar to Kerr-McGee's  Wattenberg  field and will allow  Kerr-McGee to
apply its proven expertise in tight-gas and supply-chain  management to maximize
the efficient recovery of these resources.
     Of the $3.4 billion purchase price,  approximately $2.1 billion is expected
to be  allocated  to the 297  million  barrels  of  equivalent  (BOE) of  proved
reserves  equating to approximately  $7.23 per BOE. An additional $.9 billion is
associated with 300 million BOE of probable and possible resources, or $3.10 per
BOE. The company  expects to convert these probable and possible  resources into
proved developed reserves at a cost of approximately $3.75 per BOE.
     The combined entity will have a substantial  base of low-risk  exploitation
opportunities located onshore in the U.S. Potential reserve additions from these
lower risk  properties  will supplement  Kerr-McGee's  high-potential  deepwater
exploration  program.  In  addition,  the broader  base of assets is expected to
provide a more predictable stream of production volumes.
     Kerr-McGee's  total daily  production  volume is expected to increase  more
than 34% following  completion of the  transaction.  Approximately  54% of total
daily volumes will be natural gas. Kerr-McGee has entered into hedges, primarily
in the form of costless  collars,  that when combined with  Westport's  existing
hedges,  cover  approximately  90% of Westport's  anticipated  proved production
through   2006.    Details   are   available   on   Kerr-McGee's    website   at
www.kerr-mcgee.com under the Guidance tab within the Investor Relations section.
     As a result of the transaction, Kerr-McGee's net debt as a percent of total
capitalization   is  expected  to  decrease   approximately   22%  from  54%  to
approximately  42% by year-end.  This reduced  leverage,  coupled with  expected
increased free cash flow, will enhance Kerr-McGee's  financial  flexibility.  In
addition,  the  companies  expect to realize cost savings of  approximately  $40
million  annually.  The transaction  will be accretive to both earnings and cash
flow per share beginning in 2005.

Merger Agreement
     Under the terms of the merger agreement, Westport shareholders will receive
0.71 shares of Kerr-McGee  common stock for each common share of Westport.  As a
result,  Kerr-McGee  expects to issue  approximately  49.4 million new shares to
Westport's  shareholders.  The  transaction is expected to be non-taxable to the
shareholders  of both  companies.  In  addition,  prior to  consummation  of the
transaction,  Westport will redeem all of its 6 1/2% Convertible Preferred Stock
at an anticipated redemption price of $25.65 per share.
     The transaction is contingent upon the approval by the shareholders of both
companies  as  well as  other  customary  closing  conditions.  Shareholders  of
Westport  holding  more than 42% of  Westport's  outstanding  common  stock have
entered into voting  agreements  pursuant to which such stockholders have agreed
to vote in favor of the  merger.  Kerr-McGee's  executive  management  team will
continue  in their  current  roles  after  the  close of the  transaction.  Upon
completion of the transaction, one of the current board members of Westport will
join the  Kerr-McGee  board of directors,  increasing  the size of  Kerr-McGee's
board to ten members.  The  transaction  is expected to be completed  during the
third quarter of this year.
