Item 5. Other Events    

        On July 22, 1996, Seagull Energy Corporation, a Texas corporation
("Seagull" or the "Company"), executed a definitive stock purchase agreement
(the "ESI Purchase Agreement") providing for the purchase by Seagull of all of
the outstanding common stock of Esso Suez Inc. ("ESI") from Exxon Corporation.
Also, on July 22, 1996, Seagull executed a definitive purchase agreement (the
"EEL Purchase Agreement") providing for the purchase of certain assets of Esso
Egypt Limited (the "EEL Assets") from Exxon Corporation.  The gross purchase
price, including cash and receivables, of ESI and the EEL Assets is
approximately $168 million, including $4.5 million allocated to the EEL Assets. 
The prompt collectibility of certain receivables will preclude any necessity
for financing beyond a $68 million net cash payment, funded through additional
borrowings under Seagull's existing revolving credit facilities (the "Credit
Facilities").  The effective date for the acquisition is January 1, 1996.

        ESI's assets consist of a 100% interest in the East Zeit oil producing
concession in the offshore Gulf of Suez, and the EEL Assets consist of the
entire working interest in the South Hurghada exploration concession located
onshore on the coast of the Gulf of Suez approximately 250 miles south of
Cairo.  As of December 31, 1995, net proved reserves attributable to the ESI
concession were estimated at 18.9 million barrels ("MMbbls") of crude oil. 
After accounting for the production during 1996 through the anticipated closing
date, Seagull estimates that the ESI concession area will contain approximately
17.4 MMbbls of net proved oil reserves.  The ESI concession area has current
gross production averaging approximately 16,000 barrels of crude oil per day. 
The 63,000-acre South Hurghada concession contains a number of currently
drillable exploratory prospects, plus two existing oil discoveries.

        The consummation of the purchase of ESI and the purchase of the EEL
Assets  are required to occur simultaneously and are subject to certain other
conditions, including obtaining governmental approvals and other conditions
outside the control of the parties.

        Seagull currently estimates that it will initially borrow $68 million
under the Credit Facilities to fund the purchase of ESI and the EEL Assets. 
Under provisions included in the Credit Facilities, the amount of senior
indebtedness available to Seagull is subject to a borrowing base (the
"Borrowing Base") based upon the proved reserves of Seagull's exploration and
production operations and the financial performance of its other operations. 
The Borrowing Base is generally determined annually, but may be redetermined,
at the option of either Seagull or the banks, one additional time each year. 
Prior to the purchase of ESI and the EEL Assets, the Borrowing Base was $500
million and as of August 19, 1996, borrowings outstanding under the Credit
Facilities were $175 million, leaving immediately available unused commitments
of approximately $204 million, net of outstanding letters of credit of $3
million, $100 million of borrowings outstanding under the Company's senior
notes and $18 million of borrowings outstanding under Seagull's money market
facilities.  Subsequent to the purchase of ESI and the EEL Assets, Seagull
anticipates requesting a redetermination of the Borrowing Base to increase the
Borrowing Base to $535 million, leaving immediately available unused
commitments of approximately $171 million.

                    REPRESENTATIONS AND WARRANTIES OF SELLER

its assets requires such qualification.  The copies of ESI's Certificates of
Incorporation and By-Laws (in each case, together with all amendments, if any,
thereto) that have been previously delivered to Purchaser are accurate and
complete.  ESI has full corporate power and authority to hold interests and

        2.2      Capitalization.

                 The Shares constitute all of ESI's authorized capital stock.
All of the Shares are validly issued and outstanding and are fully paid and
non-assessable.   No shares of common stock are held by ESI as treasury stock.
There is no existing option, warrant, call, commitment, or other agreement or
arrangement to which ESI is a party requiring, and there are no convertible
securities of ESI outstanding which upon conversion would require, the issuance
of any additional shares of common stock of ESI or other securities convertible
into shares of common stock or other equity security of ESI.  Except as may
otherwise be provided for under this Agreement, ESI has not, since the
Valuation Date, paid any dividend or similar distribution with respect to any
shares of its capital stock or repurchased, redeemed, or otherwise acquired any
outstanding shares of capital stock or other securities of, or ownership
interests in, ESI.

        2.3      Ownership of Shares.   Seller is the legal and beneficial
owner of the Shares, free and clear of any ownership claims by third parties
and any liens or pledges.   Seller has the corporate power and authority to
enter into and perform this Agreement, and its sale, assignment, and transfer
of the Shares will convey to Purchaser (or its assignee, per Section 10.5) good
and marketable title to the Shares, free and clear of any and all liens,
pledges, encumbrances, charges, or third party ownership claims.

        2.4      Authorization of Agreement.   The execution and delivery of
this Agreement and the consummation of the transaction contemplated hereby have

both) (a) conflict with any Certificate of Incorporation or By-Laws of Seller
or ESI, or organizational documents of SUESSO, (b) subject to the receipt of
those consents, approvals, and authorizations and the making of any

respects with the East Zeit Concession Agreement and applicable Egyptian laws,
rules, and regulations, except where any failure or violation would not have a
material, adverse effect on the business, assets or financial condition of ESI.

        2.24     Recoverable Costs.  At March 31, 1996, ESI had incurred an
aggregate of U.S.$79.7 million of unrecovered costs.  Of such costs, U.S.$59.4
million had been approved, U.S.$14.1 million were awaiting audit, and U.S.$6.3
million were pending resolution after initial audit (amounts are rounded to
nearest U.S.$0.1 million).

committed to make, in connection with the transaction contemplated by this
Agreement, any payments in the form of (a) consulting or other fees in

the purposes of Section 9.1(b)) for the same period set forth in Section

By-Laws of Purchaser, (b) subject to the receipt of those consents, approvals,
and authorizations and the making of any designation, declaration, or filing

                 (c)     PURCHASER EXPRESSLY UNDERSTANDS AND AGREES THAT,

may be incomplete or inaccurate, it will either notify Seller of its
conclusions specifically and in writing not later than ten (10) days before the
Closing or be deemed to have waived all complaints as to the incompleteness or
inaccuracy of the files or data.  For five (5) years following Closing,
however, to the extent that Seller possesses information or data that was

        4.2      Insurance.

                 (a)     Seller and Purchaser acknowledge that Exxon
Corporation maintains a worldwide program of property and liability insurance
coverage for itself and its Affiliates.  This program has been designed to
achieve a coordinated risk-management package for the entire Exxon corporate
group.  The program consists principally of three types of policies:

                         (i)      Policies issued to Exxon Corporation;

                         (ii)     Policies issued directly to Affiliates by
                                  Exxon's wholly-owned captive insurer, Ancon
                                  Insurance Company, Inc. ("Ancon"), a Vermont
                                  corporation; and

                         (iii)    Policies issued to Affiliates by a locally
                                  admitted insurer which are reinsured by
                                  Ancon.  All of the insurance policies through
                                  which the worldwide program of coverage is
                                  presently or has previously been provided are
                                  herein called the "Exxon/Ancon Policies."

                 (b)     It is understood and agreed by Purchaser that:

                         (i)      From and after August 1, 1996, no insurance
                                  coverage shall be provided under the
                                  Exxon/Ancon Policies to ESI; and

                         (ii)     From and after August 1, 1998, any and all
                                  policies previously insured or reinsured by
                                  Ancon or its predecessor companies insuring
                                  ESI shall be deemed terminated, commuted and
                                  canceled ab initio;

                         (iii)    From and after August 1, 1998, no claims
                                  regarding any matter whatsoever, whether or
                                  not arising from events occurring prior to
                                  August 1, 1996, shall be made by or for ESI
                                  against or with respect to any of the
                                  Exxon/Ancon Policies regardless of their date
                                  of issuance.

                 (c)     Purchaser shall indemnify and defend Seller and Exxon
Corporation and its Affiliates including Ancon against, and shall hold them
harmless from, any claim made after August 1, 1998,  against any of the
Exxon/Ancon Policies by or through ESI or any person subrogated to ESI's
rights, and all costs and expenses (including without limitation attorneys'
fees) related thereto.  Such indemnity shall cover, without limitation, any
claim by an insurer for reinsurance  or retrospective premium payments or any
prospective premium increases attributable to any such claim.

effect, without interruption, all insurance policies in effect as of the
Effective Date with MISR Insurance Company and to maintain the amount and scope
of coverage provided by such policies.  Costs of maintaining such insurance
shall continue to be borne by ESI, except to the extent that such costs may
increase relative to the premium(s) in effect prior to August 1, 1996, as a
result of changes in re-insurer(s) following June 1, 1996.

        4.3      Conduct of Business.  Except as expressly contemplated by this
Agreement or otherwise consented to in writing by Purchaser, from and after the
Effective Date and until the Funding Seller hereby covenants and agrees that:

conducted in the ordinary course and will use reasonable efforts to maintain,

acquire any outstanding shares of capital stock or other securities of, or
other ownership interests in, ESI;

                 (d)     Seller shall not permit ESI to merge or consolidate
with any other person or acquire a material amount of assets from any person

accounting or accounting practice, except for any such change required by GAAP;

                 (i)     Seller shall not permit ESI to expend in the aggregate
in excess of U.S.$100,000 for any non-budgeted capital expenditures;

                 (j)     Seller shall not permit ESI to enter into any futures,
hedge, swap, put, call, floor, cap, option or other contracts whose primary

                 (k)     Seller shall not permit ESI to incur any costs or

omit, to take any action necessary to prevent any such representation or
warranty from being inaccurate in any material respect at any such time.

        4.4      Hart-Scott-Rodino Filings.   Seller shall, and shall cause ESI
to, make any required filings as promptly as possible with the Federal Trade

or private party challenging the transaction contemplated hereby as violative
of antitrust or competition laws which would otherwise have the effect of
preventing the consummation of the transaction contemplated hereby; provided,

which, in its reasonable judgment, constitute a material portion of Purchaser's
total business.

        5.2      Conditions Precedent.     From and after the Effective Date

                                  favor; and

                         (iii)    all written material which the Party proposes
                                  to submit to the arbitrator.

                 (c)     On receipt by the arbitrator of the submissions
referred to above or seven (7) Business Days from his appointment, whichever is
the earlier, the arbitrator shall designate a time and place for a hearing of
the Parties on their dispute, which time shall not be more than fifteen (15)
days after the arbitrator's appointment.  The arbitrator shall be instructed to
reach his decision within five (5)  Business Days from the date of commencement

Claimor on the one hand and Claimee on the other in equal shares or in such
other proportions as the arbitrator may determine to be fair and reasonable.

                 (d)     If the arbitrator does not render a decision
(resolving the dispute, finding good cause for a Party's delay, or sanctioning
a Party for delay) within a period of twenty-one (21) days from his
appointment, for whatever reason, or such shorter or longer period as the
Parties may agree in writing, either Claimor or Claimee may, upon giving notice
to the other, terminate the appointment of the arbitrator, and a new arbitrator
shall be appointed who shall resolve the dispute in accordance with this
Section 6.3.

                 (e)     If the arbitrator determines that Claimor is entitled
to terminate this Agreement, such termination shall be without liability to
Claimor, and Claimee shall indemnify Claimor for all its reasonable costs and
expenses relating to the negotiation, preparation, and execution of this
Agreement, excluding all costs of the arbitration conducted pursuant to this
Section 6.3.

<PAGE>   34



                 (f)     In the event that Claimor serves a notice as aforesaid
on Claimee, Closing shall be postponed until after the dispute has been
resolved by the arbitrator and any time periods

referred to in Article VII of this Agreement relating to the timing of Closing
shall be frozen until receipt of the arbitrator's written determination.

                 (g)     If the arbitrator shall determine that Claimee is in
breach of the Agreement but that the breach is not sufficiently material to
entitle Claimor to terminate this Agreement, Claimor shall, after receipt of
the arbitrator's written determination, proceed to Closing in accordance with
the terms of this Agreement, without prejudice to any rights Claimor may have
to seek damages from Claimee for breach of the provisions of this Agreement.

ninety  (90)  days from Funding unless prohibited by the terms of the East Zeit
Concession Agreement (in which case Purchaser shall use all reasonable efforts
to remove or overcome such prohibition), the names of ESI and every ESI
subsidiary shall be changed to ones which do not use the words  "Exxon" or
"Esso" or "Suesso" or any name which might be confused with or similar to such
names.  Seller shall provide all necessary assistance required to complete such
name change.  Seller reserves the right to participate in the fulfillment of
such requirements, and Seller and Purchaser shall cooperate with each other to
expedite such name changes.   All expenses and costs related to such name
changes shall be for account of Purchaser.

                 (b)     Seller shall have the right, but not the
responsibility, and Purchaser shall have the responsibility, to remove ESI's
names from ESI-owned or operated properties and facilities.  Purchaser hereby
agrees to cause ESI to grant Seller a right of access after Funding to
ESI-owned or operated properties and facilities to remove ESI's names therefrom
(at Purchaser's expense) or to confirm that Purchaser has done so.  To the
extent Seller has not done so, Purchaser shall, within ninety (90) days from
Funding, remove all signs and references to ESI and shall erect or install all
signs complying with any applicable governmental rules and regulations.  At the
conclusion of the ninety (90) day term, or such earlier period as Purchaser
advises Seller that ESI's name has been removed from all properties and
facilities, Seller may inspect to confirm removal.  If removal has not been
completed Seller shall thereafter have the right to inspect each subsequent
time Purchaser advises that all signs have been removed.

                 (c)      To the extent within Purchaser's control and ability,
the provisions of Section 8.4(b) shall apply mutatis mutandis to Suesso's names,
properties, and facilities.

        8.5      Return of Seller's Proprietary Materials.   Purchaser
acknowledges and agrees that those materials set forth on Schedule 8.5 hereto
provided by Seller and/or its Affiliates for use by ESI during the period when
Seller was a stockholder of ESI will be removed by Seller prior to Closing.

        8.6      License of Data to Seller.   Purchaser hereby acknowledges
that ESI has or will license the information described in Schedule 8.5 hereto
to Seller and its Affiliates before Closing, at no cost, on the terms
stipulated in licenses with provisions to be negotiated in good faith and
mutually agreed by the Parties within ten (10) business days of the Effective
Date, and Purchaser further agrees that it shall not cause ESI to take any
actions which may in any manner invalidate or call into question the validity
of said licenses.  Such licenses will not be transferrable by Seller or its
Affiliates to any party other than Seller or an Affiliate of Seller, and Seller
and its Affiliates must treat information as Confidential ESI Information

        8.7     Confidential Information

                         (ii)    "Confidential Seller Information" means that
                                 information prepared by Seller or its
                                 Affiliate (other than ESI) or bearing Seller's
                                 or its Affiliate's (other than ESI's) name or

                         (iii)   Seller and Purchaser intend that, after
                                 Funding, neither Purchaser nor ESI will
                                 knowingly possess any Confidential Seller
                                 Information.

                         (ii)    shall make every effort to prevent the use or
                                 disclosure of  Confidential Seller
                                 Information;

                                 either destroy Confidential Seller Information
                                 or return Confidential Seller Information to
                                 the proprietor.

                (c)      For ten (10)  years commencing on the Effective Date,
Seller:

                         (i)     may not use or disclose Confidential ESI
                                 Information to any persons or entities other
                                 than itself or its Affiliates;  and

                         (ii)    shall make every effort to prevent the use or

                         (i)     if the receiving party or anyone to whom the
                                 receiving party directly or indirectly
                                 transmits the  Confidential ESI Information
                                 or  Confidential Seller Information pursuant
                                 to this Section 8.7 is requested or becomes

                                 circumstances, the receiving party, will
                                 provide the proprietor with prompt written
                                 notice so that the proprietor may inter alia
                                 seek a protective order or other appropriate
                                 remedy and/or waive compliance with the
                                 provisions of this Section 8.7.  In the event
                                 that such protective order or other remedy is
                                 not obtained, or that proprietor, in its sole
                                 discretion, expressly in writing waives

                                 8.7, the  disclosing party will furnish only
                                 that portion of the Confidential ESI
                                 Information or Confidential Seller Information
                                 (as the case may be) which it is advised by
                                 opinion of counsel is legally required and
                                 will exercise its best efforts to obtain
                                 reliable assurance that confidential treatment
                                 will be accorded the Confidential ESI
                                 Information  or Confidential Seller
                                 Information (as the case may be).

                                 of this Section 8.7 by the receiving party,
                                 which is known to the receiving party on a
                                 non-confidential basis before receipt of such
                                 information from the proprietor, or which is
                                 received subsequently from a third party in
                                 circumstances not involving the breach of a
                                 confidentiality obligation.

                (e)      Documents which proprietor considers to be subject to
any attorney-client or work product privilege as to that document or any other

pursuant to this Article IX, the other Party shall have the right after its
receipt of the related notice, at its sole option and expense, to defend
against, negotiate, settle, or otherwise deal with such proceeding, and any
Claim relating thereto or arising therefrom, and for these purposes to retain
and be represented by counsel of its choice ("Right of Defense").   The
exercise of this Right of Defense shall, however, be without prejudice to the
Protected Party's own right to participate in any such proceeding with counsel
of its choice and at its expense.  The Parties hereto agree to cooperate fully
with each other in connection with the defense,  negotiation,  appeal,  or
settlement of any such legal proceeding, claim,  or demand.

                 (b)     Purchaser shall give prior written notice to Seller of
its intention to exercise said Right of Defense.   In the event that Purchaser
elects not to exercise such Right of Defense, Seller shall defend against or
otherwise deal with any such proceeding, claim, or demand, and for these
purposes shall have the right to retain counsel, at the expense of the
Purchaser, and control the defense of such proceeding.

unforeseeable, on the Effective Date.

                 (a)     Purchaser represents to Seller that it has had no
dealings with any broker or finder in connection with the transaction
contemplated by this Agreement.   Purchaser agrees to indemnify and hold Seller
and its Affiliates harmless from and against any and all liability to which
Seller or its Affiliates may be subjected by reason of any broker's, finder's,

action taken by or on behalf of Purchaser or its Affiliate(s).

        9.8      Inducement to Seller.   Purchaser acknowledges that it
evaluated the obligations under this Article IX before it determined and
submitted its bid for the Shares and that its assumption of these obligations
is a material inducement to Seller to enter into this Agreement and close the
sale to Purchaser.

                                   ARTICLE X
                                    GENERAL

        10.1     Specific Performance.   The Parties hereto acknowledge and
agree that irreparable damage would result if this Agreement were not
specifically enforced.   Therefore, the rights and obligations of the Parties
under this Agreement, including, without limitation, their respective rights
and obligations to sell and to purchase the Shares, shall be enforceable by a
decree of specific performance issued by any court of competent jurisdiction,
and appropriate injunctive relief may be applied for and granted in connection
therewith.   Such remedies shall, however, be cumulative and not exclusive and
shall be in addition to any other remedies which any Party may have under this
Agreement or otherwise.

rights or obligations hereunder may be assigned or transferred without the
prior written consent of Seller, except that Purchaser may assign its rights
and obligations under this Agreement to any direct or indirect wholly-owned

        10.6     Headings.   The Article and Section headings contained in this
Agreement are for reference purposes only and shall not affect in any way the
meaning or interpretation of this Agreement.

        10.7.    Applicable Law; Arbitration; Submission to Jurisdiction;
Consent to Service of Process.

                 (a)     This Agreement shall be governed by, construed and
enforced in accordance with the laws of the State of New York without regard to
the conflict of law rules therein.

                 (b)     Except as provided under Section 10.1 hereof, any
dispute arising out of or relating to this Agreement, or the breach thereof,
shall be finally settled by arbitration in accordance with the Rules of
Arbitration of the International Chamber of Commerce, by three arbitrators
(except where a single arbitrator is specified herein) appointed in accordance
with said Rules.   The place of such arbitration shall be in the City of New
York, New York, USA, or such other place as mutually agreed by the Parties, and
shall be conducted in the English language.   The award rendered by the
arbitrators shall be final and binding upon the Parties.  Purchaser and Seller
waive to the extent permitted by law any rights to appeal or to review of such
award by any court or tribunal.  Purchaser and Seller agree that the arbitral
award may be enforced against them or their assets wherever they may be found
and that a judgment upon the arbitral award may be entered in any court having
jurisdiction thereof.

                 (c)     In the event that an action is brought for an
injunction or other equitable remedy in accordance with Section 10.1 hereof or
for specific performance or other equitable remedy, such action may be brought
and prosecuted in the United States District Court for the Southern District of
the State of New York (or, failing subject matter jurisdiction in such federal
court, the/an appropriate New York State court located in Manhattan, New York
City).   For this purpose each Party irrevocably: (i) submits to the exclusive
jurisdiction of the United States District Court for the Southern District of
the State of New York (or, failing subject matter jurisdiction in such federal
court, the/an appropriate New York State court located in Manhattan,





                                      41

New York City) and (ii) waives any objection which it may have at any time to
the laying of venue of any suit, action, or proceeding ("Proceedings") brought
in any such court, waives any claim that such Proceedings have been brought in
an inconvenient forum, and further waives the right to object, with respect to
such Proceedings, that such court does not have jurisdiction over such Party.
Each Party not resident in the State of New York irrevocably appoints each of
its Affiliates resident in the State of New York to receive, for it and on its
behalf, service of process in any Proceedings.   If for any reason such
Affiliates are unable to act as its agent for service of process, or the Party
does not have an Affiliate resident in the State of New York, such Party will
promptly notify the other Party and, within thirty (30) days following the
Effective Date, appoint a substitute process agent acceptable to the other
Party.   The Parties irrevocably consent to service of process given in the
manner provided for notices in Section 10.2 hereof.   Nothing in this Agreement
will affect the right of any party to serve process in any other manner
permitted by law.

        10.8     Expenses.  Whether or not the transaction contemplated hereby
is consummated, the Parties hereto shall pay their own respective expenses,
except as otherwise provided in this Agreement.

        10.9     Severability.   If at any time subsequent to the Effective
Date, any provision of this Agreement shall be held by any court of competent
jurisdiction or any validly constituted arbitral body to be illegal, void, or
unenforceable, such provision shall cease to be of any force and effect, but
the illegality or unenforceability of such provision shall have no effect upon
and shall not impair the enforceability of any other provision of this
Agreement.

        10.10    Public Announcements.   Neither Seller (nor any of its
Affiliates) nor Purchaser (nor any of its Affiliates) shall make any public
statements including, without limitation, any press releases, with respect to
this Agreement and the transaction contemplated hereby without the prior
written consent of the other Party (which consent may not be unreasonably
withheld or delayed), except as may be required by law or regulations of
national securities exchanges or commissions and then only after prior
consultation with the other Party.

        10.11    Counterparts.   This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original, but all of which taken
together shall constitute one and the same instrument.

appropriate governmental body or ongoing legal proceeding):

                 (a)     Purchaser shall cause ESI not to dispose of or destroy
any of its business records or files in existence at Closing.   If Purchaser
wishes to cause ESI to dispose of or destroy such records or files after that
time, it shall first give thirty (30) days' prior written notice to Seller, and

representatives access to all business records and files relating to ESI which
are in existence at Closing, during regular business hours and upon reasonable
notice at ESI's principal place of business or at any location where such
records are stored, and Seller shall have the right, at its own expense, to
make copies of any such records and files;  provided, however, that any such
access or copying shall be had or done in such a manner so as not to
unreasonably interfere with the normal conduct of  ESI's business or
operations, and Purchaser may condition such access or copying upon the
execution by Seller of one or more agreements that deem the information
obtained to be "Confidential ESI Information" subject to Section 8.7.

                 (c)     Purchaser shall cause ESI to make available to Seller,
upon written request and at Seller's expense,  (i)  ESI's personnel to assist

litigation, arbitration, administrative proceeding, tax return preparation, or
other matter in which Seller or any of its Affiliates are involved.

        10.13    No Admission.   Neither this Agreement, nor any part of it,
nor any performance under this Agreement, nor any payment of any amount under
this Agreement, will constitute or may be construed as a finding, evidence of,
or an admission or acknowledgment of any liability, fault, past or present
wrongdoing, or violation of law, rule, regulation, or policy, by either Seller
or Purchaser.

incorporated by reference.

The rule ejusdem generis may not be invoked to restrict or limit the scope of a
general term or phrase followed or preceded by an enumeration of particular
examples.

        10.17    Not to be Construed Against Draftor.   Purchaser acknowledges
that it has read this Agreement, has had opportunity to review it with an
attorney of its choice, and has agreed to all of its terms.   Under these
circumstances, the Parties agree that any rule of construction that a contract
be construed against the draftor shall not be applied in interpreting this
Agreement.

        10.18    Execution by the Parties.   Neither the submission of this
instrument or any information concerning the Shares for Purchaser's
examination, nor any discussions or negotiations between the Parties, shall
constitute an offer to sell a reservation of or an option for the Shares, and
this instrument and the underlying transaction will become enforceable and
binding between the Parties only upon its execution and delivery by both of
them.

                                   ARTICLE XI
                              CERTAIN TAX MATTERS

                 11.1       Certain Tax Matters.  Seller and Purchaser hereby
agree as follows:

income triggered into income by Reg.  Sections 1.1502-13, and any excess loss
accounts taken into income under Reg. Section 1.1502-19) shall be included on
the Seller's consolidated U.S. federal income tax returns for all periods
through the date of Funding and Seller shall pay any U.S. federal income taxes
attributable to such income.  ESI will furnish tax information to Seller for
inclusion in Seller's U.S. federal consolidated income tax return for the
period which includes the date of Funding in accordance with ESI's past custom
and practice.  Purchaser will be responsible for any taxes attributable to the
period after the date of Funding.

                         (b)     ESI will not elect to be excluded from the
Seller consolidated group under Reg.  Section 1.1502-76(b)(5)(ii) for the
Seller group taxable year that includes the date of Funding.

                         (c)     At Seller's request, Purchaser will cause ESI
to make or join with Seller in making any election after the date of Funding if
the making of such election is deemed necessary by Seller for pre-Funding tax
purposes and does not have a material adverse impact on Purchaser or ESI for
any post-Funding tax period.

                         (d)     Purchaser and ESI will cause ESI's Egyptian
tax return or report for the taxable period that begins before and ends after
the date of Funding to be audited by an independent tax professional before
such return or report is filed, and shall provide copies of such return or
report and the audit report to Seller, as soon as practicable, but no later
than April 30, 1997.

                11.2     IRC Sec. 338(h)(10) Election.  Purchaser agrees to
make and Seller agrees to join Purchaser in making an election under Sections
338(g) and 338(h)(10) of the Code (and any corresponding elections under state,
local, or foreign tax law) (collectively a "Section 338(h)(10) Election") with
respect to the purchase and sale of the Shares hereunder.  If Purchaser's
assignee does not file U.S. income tax returns, Seller agrees to file Internal
Revenue Service Form 8023-A, entitled "Corporate Qualified Stock Purchases," on
behalf of Purchaser's assignee with the Office of the Assistant Commissioner
(International), Attention: Chief of Examination, 950 L'Enfant Plaza South,
S.W., Washington, D.C. 20024.  Seller agrees to file Internal Revenue Service
Form 8023-A on behalf of Purchaser or its assignee with the District Director
(Attention: Chief of Examination) for the U.S. Internal Revenue district where
the U.S. principal place of business or the U.S. principal office or agency of
Purchaser (or its assignee) is located.

                                 making of the Section 338(h)(10) Election.
                                 Seller also will pay any state, local or
                                 foreign tax (and indemnify Purchaser and ESI
                                 against any adverse consequences arising out
                                 of any failure to pay such tax) attributable
                                 to an election under state, local or foreign
                                 law similar to the election

                                 tax jurisdiction (y) does not provide for or
                                 recognize an election under Section 338(h)(10)

                                 Shares.

                         (b)     Seller agrees to pay and shall be liable for
                                 all stock transfer Taxes levied or payable

                                 Purchaser.

                         (c)     Seller shall be liable for (i) all Taxes which
                                 are imposed on or incurred by ESI for any
                                 taxable period ending on or before Funding,
                                 (ii) a portion, determined as described in
                                 subsection (e) of this Section 11.3, of any
                                 Taxes which are imposed on or incurred by ESI
                                 for any taxable period which begins before and
                                 ends after Funding for that part of the
                                 taxable period up to and including the date of
                                 Funding, (iii) all Taxes that are imposed on
                                 ESI because ESI ceases on the date of Funding
                                 to be a member of a group filing consolidated,
                                 combined or unitary returns; and (iv) all
                                 Taxes of Seller and its Affiliates that are
                                 imposed on ESI solely on the basis of its
                                 joint and several liability for such Taxes
                                 (including, without limitation, any liability
                                 imposed on ESI pursuant to Reg. Section
                                 1.1502-6 for federal income taxes incurred by
                                 any member of the Seller Group other than
                                 ESI).

                         (d)     Purchaser shall be liable for all other Taxes,
                                 other than those Taxes described in
                                 subsections (a), (b), and (c) of this Section
                                 11.3, which are imposed on or incurred by ESI.

                         (e)     Whenever it is necessary for purposes of this
                                 Section 11.3 to determine the Taxes of ESI for
                                 a taxable period that begins before and ends
                                 after the Funding, the determination shall be
                                 made by assuming that ESI had a taxable period
                                 which ended at the close of





                                      46

                                 allowances and/or deductions that are
                                 calculated on an annual basis, such as the
                                 deduction for depreciation, shall be
                                 apportioned on a time basis and in accordance
                                 with ESI's audited Egyptian tax return
                                 provided for in Subsection (d) of Section 11.1
                                 hereof.  Purchaser and Seller agree that any
                                 tax apportionments will be based upon the laws
                                 and regulations applicable to the filing of
                                 any tax returns for the apportioned taxable
                                 period and will not be based solely upon the
                                 laws and regulations in effect at the time of
                                 Funding.  In the case of any property
                                 (including ad valorem) Tax, the liability for
                                 such Tax shall be allocated between Seller and
                                 Purchaser by prorating such Tax (x) to Seller
                                 in the ratio that the number of days in the
                                 taxable period prior to and including the date
                                 of Funding bears to the total number of days
                                 in the taxable period and (y) to Purchaser in
                                 the ratio that the number of days in the
                                 taxable period after the date of Funding bears
                                 to the total number of days in the taxable
                                 period.  Final settlement of any apportioned
                                 Taxes between Seller and Purchaser shall occur
                                 as soon as practicable after the returns for
                                 such Taxes are filed, but no later than 30
                                 days thereafter.

                         (f)     If Purchaser or ESI receives a refund of any
                                 Taxes described in subsections (a), (b), or
                                 (c) of this Section 11.3, Purchaser shall,
                                 within thirty (30) days after receipt of such
                                 refund, remit it to Seller.  If Seller
                                 receives a refund of any Taxes described in
                                 subsection (d) of this Section 11.3, Seller
                                 shall, within thirty (30) days after receipt
                                 of such refund, remit it to Purchaser.

                         (g)     Seller shall have responsibility for all
                                 audits and other proceedings involving the
                                 liability of ESI for Taxes for any taxable
                                 period for which Seller is solely liable under
                                 subsections (a), (b), or (c) of this Section
                                 11.3, and Purchaser shall have responsibility
                                 for all other audits and proceedings involving
                                 the liability of ESI for Taxes.  Purchaser
                                 shall give Seller notice of any proposed audit
                                 or other proceeding with respect to the
                                 liability of ESI for taxes for any taxable
                                 period that begins before and ends after the
                                 Funding which is

                                 likely to result in an additional tax
                                 liability to Seller under subsection (c) of
                                 this Section 11.3, and shall, to the extent
                                 practicable, permit Seller to participate, at
                                 Seller's own expense, in such audit or other
                                 proceeding.

                         11.4     Assistance and Cooperation.  After the 
Funding, Seller and Purchaser each shall:

                         (a)      Assist (and cause their respective Affiliates
to assist) the other Party in preparing any returns or reports which such other
Party is responsible for preparing and filing in accordance with Section 2.9

                                    ANNEX A
                    ADJUSTMENT TO PURCHASE PRICE AT FUNDING

As stated in Section 1.2, the Purchase Price consists of the Letter of Credit
plus the Purchaser Note.  For purposes of determining the amount of the Letter
of Credit, recognizing the timing delay between the Valuation Date and Funding,
in conjunction with ESI's operation in a "business as usual" mode during such
delay, which could involve costs to be incurred by ESI not recoverable under
the East Zeit Concession Agreement, Seller will make several price adjustments
as follows:

      1)     Reduce for costs incurred by ESI, including such costs charged to
             ESI by Seller or any of its Affiliates, in connection with the
             marketing and sale of ESI.

      2)     Reduce by an amount which reflects the cumulative after-tax
             interest which could be attributable to the use of the money
             accumulated in the net intercompany receivable account (i.e.,
             Seller Note 2) by Seller during the period between 1/1/96 and
             September 15, 1996.  The applicable interest rate for each
             calendar month or portion thereof will be sixty-five percent (65%)
             of the one-month Euro Currency Interest Bid Rate for U.S. Dollar
             deposits, as published in the Financial Times (New York edition)
             on the New York business day immediately preceding the first day
             of such month; this rate will be applied from the first day of
             such month to (but excluding) the first day of the following
             month.  Interest will be calculated on a daily basis by
             multiplying the end of day account balance by the applicable
             interest rate for the relevant month divided by 360.

             If one-month Euro Currency Interest Bid Rate is not published in
             the Financial Times (New York edition) on the New York business
             day required, the Parties shall attempt in good faith to agree on
             an applicable interest rate.

In regard to items #1 and 2 above, Seller agrees to pay to Purchaser or
Purchaser agrees to pay to Seller within 5 business days after Funding, in
immediately available funds, an amount equal to the difference between the
estimated Adjustment and the final Adjustment.

        3)       If within sixty ( 60 ) days after the Effective Date Purchaser
                 discovers that

        a)       (i)     ESI or SUESSO does not possess all Authorizations or
is in violation of the terms of any Authorizations or any Egyptian laws or
regulations relating to pollution control or the protection of the environment,
or

                 (ii) there is any liability of ESI or SUESSO to any
non-governmental third party in tort or otherwise in connection with any
release of any hazardous substances, solid wastes, petroleum, petroleum
products, and oil and gas exploration and production wastes into the
environment as a result of or with respect to the operations of ESI or SUESSO;
or

        (b)      there exists any pending or threatened (in writing) claim,
action, lawsuit, proceeding, or investigation against ESI or SUESSO that is not
disclosed in Schedule 2.13 or





                                      50
<PAGE>   57



otherwise disclosed or known to Purchaser prior to the Effective Date, or there
exists any material, adverse change in the matters disclosed in Schedule 2.13;

then, to the extent that any such matter does not breach a representation or
warranty of Seller set forth in Article II and Purchaser provides Seller (i) a
preliminary, summary notice as soon as practicable and (ii) a complete,
follow-up notice within ten (10) days of its discovery, the Purchase Price will
be reduced by an amount representing the reduction in value of the Shares
attributable to the matter as mutually agreed by Purchaser and Seller for each
matter that satisfies the foregoing conditions.  Purchaser's follow-up notice
must specifically identify and provide specific descriptions and evidence of
the matter and its effect on the value of the Shares.

If the parties cannot agree, after negotiating in good faith for a period of
ten (10) days, (i) that a particular matter satisfies the foregoing conditions
or (ii) on the amount by which the Purchase Price will be reduced for a
particular matter, then such dispute shall be referred to a single commercial
arbitrator in New York, who shall be appointed within five (5) business days
but otherwise in accordance with (and such arbitration shall be conducted in
accordance with) the provisions of Section 10.7.

Notwithstanding the foregoing provisions of this Section 3 of Annex A, there
shall be no purchase price reduction under this Section 3 for any matter for
which the attributable reduction in value of the Shares, as mutually agreed or
determined by arbitration, is less than U.S.$50,000.00; and, furthermore, in
lieu of any Purchase Price reduction, Seller may elect to promptly and
reasonably remedy the relevant matter before Closing, or, if the aggregate
resulting reduction for all matters under this Section 3 and the corresponding
provision in Section 1.2 of the  Purchase and Sale Agreement would exceed
$7,500,000.00, Seller may elect to terminate this Agreement.

The sum of adjustments under Sections 1, 2 and 3 above as described in this
Annex A is referred to within this Agreement as the "Adjustment."

All amounts to be determined under this Annex A shall be determined in
accordance with United States Generally Accepted Accounting Principles.

                              SCHEDULE 2.9 - TAXES



There are two salary tax disputes involving Esso Suez Inc.

- -       The Egyptian Tax Department claims that Esso Suez Inc. did not withhold
        the correct amount of Salary taxes during the years 1986-1990.  Esso
        Suez Inc. believes that its withholding practices were correct and has
        filed a court case to challenge the Tax Department's claim, which
        totals $878k.  Based upon review of the case and advice from outside
        counsel, in January 1996, $88K was deposited with the Tax Department as
        a deposit against any future liability related to that claim.  A
        Litigation hearing is scheduled for July 30, 1996.

- -       The Egyptian Tax Department claims that Esso Suez Inc. did not withhold
        the correct amount of Salary taxes during the years 1991-1994.  Esso
        Suez Inc. believes that its withholding practices were correct and is
        negotiating with the Tax Department in an attempt to resolve the claim
        without court action.  The Tax Department's original claim totalled
        $1206K but has subsequently been reduced to $454K through negotiations
        with the Tax Department.  Negotiations are continuing.

A reserve of $500k has been established on the books in connection with the
potential liability associated with these disputes.  This reserve amount may be
adjusted from time to time as new information becomes available.

4.    ESI Office Procedures

5.    Other Bonuses
      ESI has paid other special bonuses in recent years.  These bonuses are
      not covered by ESI "policies".  The amount and timing of such bonuses is
      discretionary.  
      a)     Perfect Day Bonus - A program was initiated in 1993 to reward 
             field personnel whenever they achieve a cumulative total of 10 
             "perfect" days, which are defined as days in which the field
             achieves 9 key operating parameters.  The bonus is LE 5,000 per 
             each 10 perfect days, split equally among all field personnel.
      b)     Safety Bonuses and Gifts - A safety bonus has been paid to all
             employees in recognition of achieving a one year period without
             any Lost Time Incidents (LTI).  The bonus amount is higher for
             employees in higher-risk jobs (drivers and field personnel) and
             the individual bonus payments have ranged between $75 - $200.  In
             addition, the company has provided from time to time safety gifts
             to all employees in recognition of achieving a full calendar year
             without an LTI.
      c)     Dollar Bonus - From time to time a special bonus payable in US
             dollars has been approved to reward employees that have critical 
             skills or that are high performers.  The last dollar bonus was 
             paid in September of 1995 and totaled $197k.

o       Memo dated June 3, 1996 from ECI to potential bidders for the shares of
        ESI, including Seagull Energy Corporation, regarding initial well test 
        results from A-13 following a workover.

o       Information as provided in Schedules 2.9 and 2.13 of this Stock 
        Purchase Agreement.

o       Operational activities related to the conduct of business, including:

        -        Sharing in cost of re-paving of major access road to East Zeit
                 (potential exposure estimated at ~ $50K for ESI).  Esso has
                 been asked by SUCO, who will organize and do the work, to
                 participate with other users to repair the East Zeit major
                 access road.  The road, which is private, was damaged heavily
                 in several areas due to torrential rains in 1995.  Esso is
                 expecting to receive a proposed cost sharing agreement and it
                 is reported that all of the other companies involved have
                 already agreed to proceed.  The sharing basis is 1994/95
                 actual production.  Costs will be recoverable.

        -        Repair of East Zeit platform damage.  On September 24, 1995, a
                 workboat named the Baraka II damaged the northwest boat
                 fender.  The workboat owned by the Suez Canal Authority was
                 under charter by Esso Suez at the time.  An independent
                 surveyor appointed to investigate concluded that the incident
                 was the result of "an error in judgment by the vessel's
                 master."  ESI has advised the Suez Canal Authority that they
                 will be expected to cover the actual cost of repairs to the
                 platform. The current estimate of repair costs is $163k, and a
                 claim is being prepared to submit to the Suez Canal Authority.
                 At this point we have no indication that the Suez Canal
                 Authority will fail to pay the amount claimed.

                          PURCHASE AND SALE AGREEMENT


         THIS PURCHASE AND SALE AGREEMENT is entered into by and between ESSO
EGYPT LIMITED, a Bahamian corporation ("Seller"), and SEAGULL ENERGY
CORPORATION, a Texas corporation ("Purchaser"), and is effective on the
Effective Date.

                              W I T N E S S E T H:

         WHEREAS, Seller wishes to sell to Purchaser, and Purchaser wishes to
purchase from Seller Seller's assets and assume certain obligations related to
the "Concession Agreement for Petroleum Exploration and Exploitation between
The Arab Republic of Egypt and The Egyptian General Petroleum Corporation and
Esso Egypt Limited in South Hurghada Onshore Area" dated July 27, 1991 and
issued by Egyptian Law No. 208.

         NOW, THEREFORE, in consideration of the mutual representations,
warranties, covenants, and agreements hereinafter contained, the parties hereto
agree as follows:

                                   ARTICLE I
                             THE PURCHASE AND SALE


1.1      PURCHASE AND SALE OF ASSETS

         Subject to the terms and conditions set forth in this Agreement,
Seller hereby agrees to sell, assign and transfer to Purchaser, and Purchaser
hereby agrees to purchase and accept assignment and transfer from Seller, on
the Closing Date, the following assets:

         (a)     the Concession, including recovery of all past costs
recoverable as described in Articles IV(f) and VII and the Accounting Procedure
of the Concession ("Recoverable Costs");

         (b)     various machinery, equipment, tubulars, and other tangible
property referred to in the Schedule of Assets to be Sold contained in the
Disclosure Schedule ("Inventory");

         (c)     permits and licenses related to the Concession; and

         (d)     the Contracts (as defined in Section 2.9 below).

         Specifically excluded from the Assets are cash, cash deposits (other
than leasehold deposits), other cash equivalent investments, insurance policies
and security bonds.

         If within two (2) years after the Closing Date Purchaser shall be
advised by an applicable governmental authority or reasonably consider that any
deeds, bills of sale, assignments or assurances or any other acts or things are
necessary, desirable or proper to vest, perfect or confirm, of record or
otherwise, in Purchaser (or its assignee), its right, title or interest in, to
or





                                       1
<PAGE>   7
under any of the Assets, Seller or its successor (as appropriate) shall execute
and deliver all such deeds, bills of sale, assignments and assurances and do
all such other acts and things reasonably necessary, desirable or proper to
vest, perfect or confirm Purchaser's (or its assignee's) right, title or
interest in, to or under any of the Assets.

1.2      PURCHASE PRICE AND PAYMENT

         (a)     Purchaser shall pay to Seller a total aggregate price of Four
Million Five Hundred Thousand United States Dollars (U.S. $4,500,000.00), less
any purchase price reduction in accordance with Section 1.3 below, on the
Closing Date.  Purchaser's  payment shall be effected by providing to Seller an
irrevocable letter of credit ("Letter of Credit") in the form of Attachment E
hereto.

1.3      PURCHASE PRICE REDUCTION

         (a)     If within sixty (60) days after the Effective Date Purchaser
discovers that:

                 (i)      Seller does not possess all Authorizations (as
defined in Section 2.13(a)) or is in violation of the terms of any
Authorizations or any Egyptian laws or regulations relating to pollution
control or the protection of the environment or (ii) there is any liability of
Seller to any non-governmental third party in tort or otherwise in connection
with any release of any hazardous substances, solid wastes, petroleum,
petroleum products, or oil and gas exploration and production wastes into the
environment as a result of or with respect to Seller's operation of the
Concession;

then, to the extent that any such matter does not breach a representation or
warranty of Seller set forth in Article II and Purchaser provides Seller (A) a
preliminary, summary notice as soon as practicable and (B) a complete,
follow-up notice within ten (10) days of its discovery, the purchase price will
be reduced by an amount representing the reduction in the value of the
Concession attributable to the matter as mutually agreed by Purchaser and
Seller for each matter that satisfies the foregoing conditions.  Purchaser's
follow-up notice must specifically identify and provide specific descriptions
and evidence of the matter and its associated reduction in value.

         (b)     If the parties cannot agree, after negotiating in good faith
for a period of ten (10) days, (i) that a particular matter satisfies the
conditions of Paragraph (a) above or (ii) on the amount by which the purchase
price will be reduced for a particular matter, then such dispute shall be
referred to a single commercial arbitrator in Houston, Texas, who shall be
appointed within five (5) business days but otherwise in accordance with (and
such arbitration shall be conducted in accordance with) the provisions of
Section 10.7.

         (c)     Notwithstanding the foregoing provisions of this Section 1.3,
there shall be no purchase price reduction for any matter for which the
associated reduction in the value of the Concession, as mutually agreed or
determined by arbitration, is less than U. S. $50,000.00 and furthermore, in
lieu of any purchase price reduction, Seller may elect to promptly and
reasonably remedy the relevant matter before Closing, or, if the aggregate
resulting reduction for all matters





                                       2

under this provision and the similar provision contained in Section 4 of Annex
A of that certain Stock Purchase Agreement by and between Exxon Corporation and
Purchaser dated July 22, 1996 (the "Stock Purchase Agreement") would exceed U.
S. $7,500,000.00, Seller may elect to terminate this Agreement.

1.4      PAYMENT OF TAXES AND OTHER CHARGES

         Purchaser shall pay, on the Closing Date or, if due thereafter
promptly when due, all transfer taxes, sales taxes, stamp taxes, and any other
taxes (other than income taxes payable by Seller) payable in connection with
the transactions contemplated hereby up to a maximum of U. S. $50,000.  Seller
and Purchaser shall mutually agree to the appropriate allocation between the
parties of any such taxes in excess of U. S. $50,000; provided that in no event
shall Purchaser be required to pay any such taxes in an amount in excess of U.
S. $100,000.

1.5      ASSUMPTION OF OBLIGATIONS

         Effective the Closing Date, Purchaser shall assume and thereafter pay,
perform or discharge, all of the obligations and liabilities relating to the
Assets, including but not limited to those described in the Disclosure Schedule
and the obligation described in Section 1.6 below.  Notwithstanding the
foregoing sentence, Purchaser shall have no obligation to assume, pay, perform
or discharge the matters set forth in Section 2.10 (i) and (ii)of the
Disclosure Schedule and in Sections 2.12, 2.16, 8.6, 9.2(b) and 9.8 of  this
Agreement.

1.6      SECOND EXTENSION TO THE EXPLORATION PERIOD

         Purchaser has requested Seller to enter into the second extension to
the exploration period.  In accordance with Article III(b) of the Concession,
Seller submitted such notice of intent to enter the second extension period to
EGPC on June 26, 1996.  When Seller further advises EGPC of the
corner-coordinates and map identifying the areas to be retained and the areas
to be relinquished in accordance with Article V(a) of the Concession, Seller
will use the corner- coordinates and map as provided by Purchaser with its bid
transmittal letter dated June 6, 1996.  If Closing does occur, Purchaser
assumes responsibility for the costs of entering into the second extension
period, including but not limited to the cost associated with  and obligation
to drill an additional qualifying exploration well under the Concession.

arbitrator and a new arbitrator shall be appointed who shall resolve the

by the arbitrator and any time periods referred to in Article VII of this
Agreement relating to the timing of Closing shall be frozen until receipt of
the arbitrator's written determination.

         (g)     If the arbitrator shall determine that Claimee is in breach of
the Agreement but that the breach is not sufficiently material to entitle
Claimor to terminate this Agreement, Claimor shall, after receipt of the
arbitrator's written determination, proceed to Closing in accordance with the
terms of this Agreement, without prejudice to any rights Claimor may have to
seek damages from Claimee for breach of the provisions of this Agreement.

coverage as of Closing Date.

Section 2.6      Description of Current Status of Concession

Esso Egypt Limited (EEL) received a preliminary award of the South Hurghada
Concession in November of 1989.  By letter dated November 30, 1989, EGPC
allowed costs incurred pending final approval to be subject to cost recovery.

On June 14, 1990, the Ministry of Petroleum and Mineral Resources issued
Decision No. 98 of 1990.  The Decision prohibited the granting of concessions
for exploration of petroleum and gas within specified areas of the Red Sea and
South Sinai.  Portions of what would eventually become the South Hurghada
Concession were covered by the decision.

The South Hurghada Concession Agreement was executed on July 24, 1991.  After
final approval of The People's Assembly on June 10, 1991, the concession was
issued as Law No. 208 of 1991.  Before final approval, EEL discussed its
exploration plans with the Petroleum Ministry, EGPC and the Egyptian Cabinet
Ministers to assure the compatibility of EEL's plans with environmental and
tourism interests.  By letter dated July 16, 1991, EEL advised EGPC that while
conducting petroleum operations, Esso undertakes that (a) no petroleum
structures will be erected and (b) there will be no drilling operations nearby
tourist installations within the three kilometer area, unless previously agreed
with EGPC.  By letter dated July 16, 1991, Esso Suez Inc. undertakes that, if
EEL spends during the initial three years exploration period of said agreement
less than the minimum amount for such a period (U.S. $8 million), Esso Suez
Inc. shall transfer to EGPC a quantity of crude oil sufficient in value to
cover EEL's shortfall.

In March 1992, the Ministry of Tourism and the Ministry of Petroleum entered
into a Joint Cooperation Agreement to determine the conditions in which the
land along the Red Sea Coast between the City of Suez and the Sudan Borders
would be used for touristic and petroleum activity. Paragraph 6 recognizes the
South Hurghada Concession and provides that the agreement does not apply to
lands assigned for petroleum activities of previous concessions issued before
the approval of this Cooperation Agreement, which are lands interfering with
the areas assigned for tourism under the Cooperation Agreement.  Paragraph 7 of
the agreement does refer to possible mutual activity between Tourism and
Petroleum in the Sahl Hashish area of the South Hurghada Concession.  The Sahl
Hashish area of the concession has been relinquished.

By letter dated June 22, 1994, EEL advised EGPC of EEL's intent to extend the
initial exploration period for the South Hurghada Concession and its intent to
relinquish, effective July 27, 1994, twenty-five (25) percent of the original
concession area.  By its June 29, 1994 letter, EGPC concurred with EEL's
requested extension.

EEL has met all of the obligations of the first exploration period (3 wells,
U.S. $8 million) and the first extension period (1 well, U.S. $3 million)
having acquired over 400 km of 2-D seismic data, drilled four exploration
wells, and spent over U.S. $18 million.

EGPC has approved over U.S. $14 million of the U.S. $18 million spent as
creditable towards the spending obligations and eligible for cost recovery in
accordance with the concession.

A notice of intent to extend the exploration period for the second two year
extension period is permitted in accordance with Article III (b) of the South
Hurghada Concession.  Such notice needed to be provided by June 27, 1996.  EEL
has met all of the work and expenditure obligations of the first exploration
period and first extension period.  EEL would be required to relinquish,
effective July 27, 1996, an additional twenty-five (25) percent of the original
concession and commit to drill an additional exploration well.

On June 26, 1996, EEL submitted to EGPC a notice to enter the second two year
extension period for the South Hurghada Concession.  EEL requested EGPC's
concurrence to identify at a later date the twenty-five percent (25%) of the
original concession to be relinquished.  On July 2, 1996, EGPC advised EEL that
it has no objection to EEL entering the second two year extension period and
required EEL to identify the twenty-five percent (25%) relinquishment area
before July 27, 1996.  It also advised EEL that if any financial deficiency is
discovered during the audit for the second exploration phase, EEL will need to
settle it in cash with EGPC.

         EEL does not have any patents or copyrights.

                 September 12, 1996.

                       REPORT OF INDEPENDENT ACCOUNTANTS


August 15, 1996

To the Board of Directors and
  Shareholder of Esso Suez Inc.

In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of income, of shareholder's equity and of cash flows
present fairly, in all material respects, the financial position of Esso Suez
Inc. and its subsidiaries at December 31, 1995 and 1994, and the results of
their operations and their cash flows for each of the three years in the period
ended December 31, 1995, in conformity with accounting principles generally
accepted in the United States of America.  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 of these statements in accordance with generally accepted auditing
standards which require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management,
and evaluating the overall financial statement presentation.  We believe that
our audits provide a reasonable basis for the opinion expressed above.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS



NOTE 1 - ORGANIZATION AND ACTIVITIES

Esso Suez Inc. (the "Company"), a Delaware corporation, is a wholly owned
subsidiary of Exxon Corporation.  The Company established an Egyptian Branch,
Esso Suez Inc. (Egypt Branch) (The "Branch") in 1981 for the purpose of
exploration and production of petroleum and hydrocarbons in the East Zeit
offshore concession area (the "Concession") in accordance with the terms of the
concession agreement dated March 23, 1981 between the Government of the Arab
Republic of Egypt, the Egyptian General Petroleum Corporation ("EGPC"), and the
Branch.  An Esso Suez Inc. home office was established in 1989.  The home
office has no employees, and is used solely for recording various
non-recoverable intercompany charges.  A commercial discovery was declared in
the concession in 1984.  Crude oil production began on December 22, 1985.  As
of December 31, 1995, seventeen development wells have been drilled in the
concession area.

NOTE 2 - ACCOUNTING POLICIES

CONSOLIDATION.  The accompanying consolidated financial statements include the
accounts of the Company's home office, whose books are maintained in Houston,
Texas, and the Branch.  All significant intercompany transactions have been
eliminated.

INVENTORIES.  Inventories are carried at the lower of current market value or
cost.  The cost of crude oil inventory is determined under the last-in,
first-out ("LIFO") method.  The cost of remaining inventories are determined
under the weighted average cost method.

PROPERTY, PLANT AND EQUIPMENT.  Depreciation, depletion and amortization, based
on cost, are primarily determined under either the unit of production or
straight-line method.  Unit of production rates are based on oil to be
recoverable from proven developed reserves.  The straight-line method of
depreciation is based on estimated asset service life.  Maintenance and repairs
are expensed as incurred.  Major renewals and improvements are capitalized.

The Company's exploration and production activities are accounted for under the
"successful efforts" method.  Under this method, costs of productive wells and
development dry holes, both tangible and intangible, as well as productive
acreage are capitalized and amortized using the unit of production method.
Costs of that portion of undeveloped acreage likely to be unproductive, based
largely on historical experience, are amortized over the period of exploration.
Other exploratory expenditures, including geophysical costs and other dry hole
costs, are expensed as incurred.

In March 1995, the Financial Accounting Standards Board issued Statement No.
121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed Of."  This statement had no impact on the Company's
results of operations or financial position upon adoption in January 1996.

ENVIRONMENTAL LIABILITIES.  The Company is not aware of any environmental
liabilities at this time.  The Egyptian Peoples Assembly passed environmental
legislation in 1993 that effectively codifies international environmental
conventions.  During 1995, certain of the executive regulations relating to
this legislation were published and are scheduled to go into effect in 1998.
The regulations that have been issued are very preliminary, and it is uncertain

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS



USE OF ESTIMATES.  The preparation of financial statements in conformity with
accounting principles generally accepted in the United States requires
management to make estimates that affect the reported amounts of assets,
liabilities, revenues and expenses, and the disclosure of contingent
liabilities.  Actual results could differ from these estimates.

NET INCOME PER SHARE.  Net income per share of common stock is based on the
monthly weighted average number of common shares outstanding during the year.

NOTE 3 - CASH FLOW INFORMATION

No cash payments were made by the Company for interest expense and income taxes
for the three year period ended December 31, 1995.  Income taxes are paid on
the Company's behalf by EGPC, in accordance with the terms of the concession
agreement.

NOTE 4 - FINANCIAL INSTRUMENTS AND CREDIT RISK

The carrying value of accounts receivable, accounts payable, and short-term
obligations approximate their fair value.  Crude oil sales to EGPC during 1995,
1994 and 1993 amount to $53,036,000, $27,161,000 and $22,448,000, respectively.
Accounts receivable from EGPC as of December 31, 1995, 1994 and 1993 total
$7,893,000, $6,979,000 and $4,532,000, respectively.  Although collection of
these receivables could be influenced by economic factors affecting this
organization, the risk of significant loss is considered remote.

NOTE 8 - INCOME TAXES
                     
In accordance with the terms of the concession agreement, EGPC pays Egyptian
corporate income taxes and development duties on the Company's behalf.
Accordingly, no liability is recorded on the books of the Company as of
December 31, 1995 and 1994 for such taxes and duties.  The petroleum sector
corporate tax rate of 40.55 percent and the development duty tax of two percent
have remained unchanged during the years 1995, 1994 and 1993.  Deferred income
tax accounts are not utilized in Egypt given the nature of Egyptian Petroleum
Sector taxation.

accounting principles ("GAAP") to statutory income and the related statutory
income tax expense follows:

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS



NOTE 9 - SHAREHOLDER'S EQUITY

COMMON STOCK.  The Company was incorporated by authorizing and issuing 1,000
shares of common stock with a par value of $100 per share.  No additional
shares were authorized and issued thereafter.

DONATED CAPITAL.  Prior to 1993, the shareholder of the Company made capital
contributions by converting, in installments, receivables due from the Company
totalling $133,223,000.

NOTE 10 - COMMITMENT AND CONTINGENCIES

LEASE COMMITMENTS:  The Company leases certain office space and equipment under
operating lease agreements which contain renewal options and escalation
clauses.  Future minimum rental payments under these leases range between
$100,000 and $500,000 in each of the years 1996-2000.  No future minimum lease
rental payments are due for years beyond.  All operating leases contain
provisions allowing the Company to cancel the leases before the end of the
lease term.

Total rental expense under operating leases for 1995, 1994 and 1993 was
approximately $538,000, $494,000 and $453,000, respectively.

CONCENTRATIONS OF RISK: The future of the exploration and production segment
will be affected by the market prices of crude oil.  The availability of a
ready market for crude oil in the future will depend on numerous factors beyond
the control of the Company, including weather, production of other crude oil
imports, marketing of competitive fuels, proximity and capacity of crude oil
pipelines and other transportation facilities, any oversupply or undersupply of
crude oil, the regulatory environment, and other regional and political events,
none of which can be predicted with certainty.

LITIGATION:  The Company is a party to ongoing litigation in the normal course
of business.  Management regularly analyzes current information and, as
necessary, provides accruals for probable liabilities on the eventual
disposition of these matters.  While the out-come of lawsuits or other
proceedings against the Company cannot be predicted with certainty, management
believes that the effect on its financial condition or results of operations,
if any, will not be material.

NOTE 11 - SUBSEQUENT EVENT:

Seagull Energy Corporation on July 22, 1996 signed a definitive stock purchase
agreement with Exxon Corporation to acquire all of the outstanding capital
stock of the Company.  The stock sale is expected to close on or about
September 10, 1996, and Exxon and Seagull are currently working together to
design and implement a transition plan intended to minimize the impact of the
sale on the Company's operations.  The terms of the stock purchase agreement
are such that there is no effect on the Company's national staff and that
essential Company agreements and contracts will either continue in force after
the stock sale or will be replaced by equivalent agreements or contracts.

The reserve volumes are estimates only and should not be construed as being
exact quantities.  These reserves may or may not be recovered and may increase
or decrease as a result of future operations of the Company and changes in
market conditions.  The Company's standardized measure of discounted future net
cash flows and changes therein as of December 31, 1995, 1994 and 1993 are based
substantially on the present value of future net revenues from proved crude oil
reserves estimated by qualified petroleum engineers in accordance with
guidelines established by the  United States Securities and Exchange
Commission.  These estimates were computed by applying appropriate year end
prices for crude oil to estimated future production of proved crude oil
reserves over the economic lives of the reserves and assuming continuation of
existing economic conditions.  Year end 1995 calculations were made utilizing
average prices for East Zeit crude oil as of December 31, 1995 of $18.66 per
barrel ("Bbl").

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)


NOTE 1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Presentation of financial information

        In the opinion of management, the unaudited condensed consolidated
financial statements contain all adjustments necessary to present fairly the
financial position of Esso Suez Inc.  (the "Company" or "ESI"), a wholly-owned
subsidiary of Exxon Corporation ("Exxon"), as of June 30, 1996, and the results
of its operations and cash flows for the six months ended June 30, 1996 and
1995.  All adjustments made are of a normal, recurring nature.  The results of
operations for the six  months ended June 30, 1996 are not necessarily
indicative of the results to be expected for the full year.

        The financial information presented herein should be read in
conjunction with ESI's financial statements and notes for the year ended
December 31, 1995.

Cash Flow Information

        No cash payments were made by the Company for interest expense and
income taxes for the six months ended June 30, 1996 and 1995.  Income taxes are
paid on the Company's behalf by the Egyptian General Petroleum Corporation, in
accordance with the terms of the concession agreement.

Net Income Per Share

        Net income per share of common stock is based on the monthly weighted
average number of common shares outstanding during the year.

NOTE 2.  COMMITMENTS AND CONTINGENCIES

        The Company is a party to ongoing litigation in the normal course of
business. Management regularly analyzes current information and, as necessary,
provides accruals for probable liabilities on the eventual disposition of these
matters. While the out-come of lawsuits or other proceedings against the
Company cannot be predicted with certainty, management believes that the effect
on its financial condition or results of operations, if any, will not be
material.

NOTE 3.  SUBSEQUENT EVENT

        Seagull Energy Corporation on July 22, 1996 signed a definitive stock
purchase agreement with Exxon to acquire all of the outstanding capital stock
of the Company.  The stock sale is expected to close on or about September 10,
1996, and Exxon and Seagull are currently working together to design and
