               UNAUDITED PRO FORMA CONDENSED FINANCIAL INFORMATION

     On September 10, 1996, Seagull Energy Corporation  ("Seagull") acquired all
of the outstanding  common stock of Esso Suez Inc. ("Esso Suez") (the "Esso Suez
Acquisition")  and certain assets of Esso Egypt Limited for a net purchase price
of  approximately  $74 million in cash. On October 3, 1996, the  shareholders of
Seagull  and the  shareholders  of  Global  Natural  Resources  Inc.  ("Global")
approved a stock merger (the "Merger")  whereby each outstanding share of Global
common  stock was  converted  into .88 of share of  Seagull  common  stock  (the
"Common Stock Exchange Ratio").

     The unaudited pro forma condensed statements of earnings for the six months
ended  June 30,  1996  and each of the  years  in the  three-year  period  ended
December  31, 1995 give effect to (i) the Merger  using the pooling of interests
method  of  accounting  for  business   combinations  and  (ii)  the  Esso  Suez
Acquisition,  financed under Seagull's  revolving credit facilities (the "Credit
Facilities"),  as if the  acquisition  had  occurred  on January  1,  1995.  The
unaudited pro forma condensed  balance sheet as of June 30, 1996 gives effect to
(i) the Merger using the pooling of interests  method of accounting for business
combinations  and (ii) the Esso Suez  Acquisition,  financed  under  the  Credit
Facilities,   as  if  the  acquisition  had  occurred  on  June  30,  1996.  The
transactions  contemplated  by the Merger will be accounted  for as a pooling of
interests  whereby the assets,  liabilities and results of operations of Seagull
and Global  are  combined  using the  historical  cost-based  amounts of the two
separate entities.

     The unaudited pro forma information  presented is based upon the respective
historical  consolidated  financial statements of Seagull,  Global and Esso Suez
and should be read in conjunction with such financial statements and the related
notes thereto. Estimated pre-tax expenses of approximately $8 million related to
effecting the Merger of Seagull and Global will be deducted in  determining  the
net income of the combined  enterprise  for the period in which the expenses are
incurred.  The  effects of such  expenses  are not  reflected  in the  following
unaudited  pro forma  condensed  financial  statements.  The unaudited pro forma
condensed  financial  information  has been prepared from, and should be read in
conjunction  with, the historical  consolidated  financial  statements and notes
thereto of Seagull,  Global and Esso Suez.  The unaudited pro forma  information
presented  does not  purport  to be  indicative  of  actual  results,  as if the
combinations had been in effect on the dates of or for the periods indicated, or
of future results.
