     NOW,  THEREFORE,  for and in consideration of the mutual  agreements herein
contained,   and  other  good  and  valuable  consideration,   the  receipt  and

     3. Closing and Effective Date.

          (a) The closing of the sale and  purchase of the  Property  shall take
place on or  before  December  15,  1997  (the  "Closing"),  at the  offices  of
Purchaser,  or at such other time, place or manner as may be mutually  agreeable
to the parties. The sale of the Property shall be effective as

                                        2





of 7:00 a.m. Central Standard Time, on November 1, 1997 (the "Effective  Date").
It is the intent of the parties  that  Purchaser  shall be  responsible  for all
costs  associated with operating the Property after the Effective Date and shall
be entitled to all revenues  attributed  by the  purchaser of  production to the
month of November 1997, and thereafter.

          (b) At the Closing,  the Property shall be conveyed and transferred by
Sellers to Purchaser by the execution and delivery of an Assignment  and Bill of
Sale (the "Assignment") in substantially the form of Assignment and Bill of Sale
attached hereto as Exhibit "B", and such other  instruments of conveyance as may
be requested by Purchaser. Purchaser shall be entitled to all of Sellers' rights
as described in Exhibit "A" (including,  without  limitation,  the rights to all
Production  and proceeds of  Production)  appurtenant  and  attributable  to the
Property  and shall be  subject to the duties  and  obligations  attendant  with
ownership  of the  Property  for the period from and after the  Effective  Date.
Sellers shall be entitled to all of the rights (including,  without  limitation,
the  rights to all  Production  and  proceeds  of  Production)  appurtenant  and
attributable  to the Property and shall be subject to the duties and obligations
attendant with ownership of the Property,  for the period prior to the Effective
Date.

     4.  Adjustments to Purchase Price.  The Purchase Price shall be adjusted at
the Closing in accordance with the "Interim Settlement  Statement"  (hereinafter
defined) and in accordance with the "Final  Settlement  Statement"  (hereinafter
defined) as follows:

               (1) the value of all  merchantable  allowable oil or other liquid
hydrocarbons  in storage  owned by  Sellers  in the tanks or above the  pipeline
connection  or not  otherwise  accounted  for by  Purchaser  (to be based on the
October  1997  prices  received  by  Sellers)  at the  Effective  Date,  and not
previously  sold by  Sellers,  that is credited  to the  Property  valued at the
contract  price  thereto,  or if none,  the  market  price in  effect  as of the
Effective Date, less taxes or gravity  adjustments  deducted by the purchaser of
such oil or other liquid hydrocarbons;

               (2) the amount of all reasonable  expenditures made in connection
with  the  ownership,  operation  and  maintenance  of the  Property  (including
royalties  and rentals) and in accordance  with  generally  accepted  accounting
principles  ("GAAP") and prudent  operations,  attributable solely to the period
from and after the Effective  Date and which are paid by or on behalf of Sellers
after the Effective Date.  Notwithstanding  anything in this Agreement,  Sellers
shall be solely  responsible  for all  tangible  and  intangible  capital  costs
relative to the  drilling,  completion  and placing on  production  of the Wells
incurred prior to Closing,  including but not limited to,  seismic  acquisition,
surface damages,  pipeline rights-of-way,  and surface restorations (hereinafter
referred to as "Capital  Expenditures");  provided  however,  that the  Purchase
Price  will be  increased  by an  amount  equal to all lease  acquisition  costs
relating  to  prospects  that  are  incurred  by  Sellers,  to the  extent  such
acquisitions are approved in advance in writing by Purchaser;

               (3) an amount equal to all prepaid  expenses  attributable to the
ownership,  operation  and  maintenance  of the Property  that are paid by or on
behalf of Sellers  after the  Effective  Date and prior to the Closing  Date and
that are, in  accordance  with GAAP  attributable  solely to the period from and
after the Effective Date; and

                                        3





               (4) to the extent the agreements affecting same are acceptable to
Purchaser, any other amount agreed upon by Purchaser and Sellers.

          (b) The Purchase Price shall be decreased by the following:

               (1) the  amount  of any  proceeds  from  the  sale of  Production
attributable  to the period on or after the Effective  Date (net of  production,
severance  and  similar  taxes and  assessments  measured  by or payable  out of
production) actually received or accrued by or on behalf of Sellers;

               (2)  an  amount  equal  to  all  unpaid  ad  valorem,   property,
production,  profit,  severance and similar taxes and assessments  based upon or
measured by the ownership of the Property or the production of oil, gas or other
minerals therefrom or the receipt of proceeds attributable thereto, which accrue
to or are chargeable  against the Property (in  accordance  with GAAP) and which
are attributable to the period prior to the Effective Date;

               (3)  any  amounts  received  by  Sellers  (whether  prior  to  or
subsequent to the Effective Date) pursuant to "take-or-pay,"  advance payment or
similar  provisions  of  any  production  sales  contract,   any  gas  balancing
agreement,  or any other agreement, to the extent any purchaser has the right to
apply any such amounts to Production delivered after the Effective Date;

               (4) any reduction in the value of the Property resulting from the
existence of a Defect (as defined  herein) which is not cured or waived prior to
Closing; and

               (5) any other amount agreed upon by Purchaser and Sellers.

          (c) All monies received by either party hereto which,  under the terms
of this Agreement or otherwise,  belong to the other party, shall be received in
trust by the party  receiving such funds,  and shall monthly,  upon receipt,  be
paid over to the other party.  The parties agree,  in this regard,  to cooperate
fully and to execute,  endorse and deliver as  expeditiously as practicable such
papers,  checks and documents as are needed promptly to complete the transfer of
such payments;

          (d)  After  the  Closing,  if  an  invoice  or  other  evidence  of an
obligation  relating to the Property is received  which is applicable to periods
both prior to and after the  Effective  Date,  and is partly the  obligation  of
Sellers and partly the  obligation of  Purchaser,  then each party shall pay its
respective  portion of such  obligation  to the  obligee,  prorated  between the
parties as of the Effective Date;

          (e) At and after the Closing,  Purchaser  and Sellers  will  cooperate
fully in notifying  all  applicable  third parties  (including  the execution by
Sellers of such transfer orders,  letters in lieu, change of operator,  etc., as
may be requested by Purchaser) so that notices,  proceeds and invoices from such
third  parties may take into  account the fact that  Purchaser  has acquired the
Property as of the Effective Date;

          (f) The provisions of this Section 4 shall survive the Closing hereof.


                                        4





     5. Property  Conditions,  Title Review,  Property  Information and Casualty
Losses.

          (a)  Property  Conditions.  Sellers  agree  that for a period  of time
commencing upon the date of this Agreement and continuing  until 5 business days
before  Closing  (the "Review  Period"),  Purchaser,  personally  or through its
authorized agents or  representatives,  shall have the right to make any and all
physical  inspections of the Property  which  Purchaser may desire to make or to
have  made and to make  all  such  other  inspections,  surveys,  tests or other
studies  (including,   but  not  limited  to,   environmental   assessments  and
evaluations)  as Purchaser  deems  necessary or  desirable.  Purchaser,  and its
authorized agents and  representatives,  with prior notice to Sellers, may enter
upon the  Property for the purpose of  conducting  those  inspections,  surveys,
tests,  and studies.  If Purchaser  shall  determine  that the  condition of the
Property  is not in  compliance  with any  governmental  regulations  (including
environmental  regulations),  then upon  discovery  Purchaser must promptly give
written notice to Sellers (but in no event later than the last day of the Review
Period) of such condition.  Upon receipt of such notice,  Sellers shall have the
option,  but not the  obligation,  to (a) cure or remedy such  condition  to the
satisfaction of Purchaser (if current  remediation of such condition is required
by a governmental agency,  Sellers agree that the condition shall be remedied in
accordance  with  and  to  the   satisfaction   of  the   appropriate   agency's
requirements); or (b) agree with Purchaser on a reduction to the Purchase Price,
which reduction shall reflect Purchaser's cost to remedy such condition.  If the
condition  cannot  be cured  or  remedied  to  Purchaser's  satisfaction  and if
agreement  cannot be  reached  on  reduction  to the  Purchase  Price,  then the
affected  Property may be excluded by Purchaser from the Property to be acquired
by Purchaser  hereunder and the Purchase Price shall be reduced according to the
value of the affected Property (or that portion of such Property so affected) as
determined by the allocated  value shown on Schedule 2. In the event the parties
fail to agree upon the  implementation  of either  subclause (a) or (b) prior to
Closing,  and if a reduction of more than 20% in the Purchase Price results from
the  exclusion by Purchaser of the affected  Property,  Purchaser  may terminate
this Agreement by delivery of written notice so indicating to Sellers,  in which
event this  Agreement  shall  terminate,  and the parties  hereto  shall have no
further  rights  or  obligations  under  this  Agreement.   Notwithstanding  the
foregoing,  Purchaser  shall not be  entitled  to  exclude  Main  Pass  Block 25
pursuant to a Defect unless  Purchaser also excludes Main Pass Block 21 from the
purchase hereunder.

          (b)  Defects.   During  the  Review  Period,   Sellers  shall  provide
Purchaser, personally or through its authorized agents or representatives,  full
access during normal  business hours to the Selling Group  Representative's  (as
defined  herein)  office  and  premises  to  review  and  inspect  all  Records,
including,  but not limited to, all abstracts of title, lease files, unit files,
production and marketing files,  title opinions,  title files, title records and
other  files or  information  in any  Seller's  possession  or to which any such
Seller has access which relate to the Property and the status of Sellers'  title
thereto,  and Purchaser shall have the right to make and retain copies of any of
such Records.

          (c)  Notice  of  Defect.  If  during  the  Review  Period,   Purchaser
determines that the Property is subject to a Defect, Purchaser must give written
notice to Sellers of such Defect,  the nature of the Defect and furnish  Sellers
Purchaser's  basis for the assertion of such Defect.  As soon as practical after
such  written  notice,  but no later  than (3)  business  days  after the Review
Period, Sellers and Purchaser shall meet and use a good faith effort to agree on
the Purchase Price  adjustment for such Defect.  If Sellers and Purchaser cannot
agree in good faith on the amount of such a

                                        5





Purchase Price  adjustment,  such amount shall be determined in accordance  with
the following guidelines:

               (1) If the Defect is that a Seller's Net Revenue Interest ("NRI")
for any Property is less than the NRI for such  Property as set forth in Exhibit
"A", then the portion of the Purchase Price for such Property,  as determined by
Schedule 2, shall be adjusted in the same  proportion  that the actual NRI bears
to the NRI shown in Exhibit "A";

               (2) If the Defect is a lien, encumbrance or other charge upon the
Property  which is liquidated in amount,  then the  adjustment  shall be the sum
necessary to be paid to the obligee to remove the Defect from the Property;

               (3) If the Defect is  curable  and  Sellers  desire to attempt to
cure such  Defect,  the  Purchase  Price paid at Closing  will be reduced as set
forth  herein;  however,  Sellers  shall have a period of 60 days from and after
Closing in which to cure such Defect. If Sellers are able to cure such Defect to
the satisfaction of Purchaser  within the 60 day period,  Purchaser shall pay to
Sellers a sum equal to the  amount  deducted  from the  Purchase  Price for such
Defect; and

               (4) If the Purchase  Price  adjustment for any such Defect cannot
be  determined  pursuant  to clauses  (1),  (2) or (3) above,  and  Sellers  and
Purchaser  cannot  otherwise agree in good faith on the amount of the adjustment
to the  Purchase  Price,  Purchaser  may (1) waive the Defect and  proceed  with
Closing or (2) exclude the affected Property and reduce the Purchase Price based
upon the value of the affected Property as set forth in Schedule 2. In the event
exclusion  of the affected  Property or  adjustment  due to Defect  results in a
reduction of more than 20% of the Purchase  Price,  Purchaser may terminate this
Agreement by delivery of written notice so indicating to Sellers, in which event
this  Agreement  shall  terminate,  and the parties hereto shall have no further
rights or  obligations  under this  Agreement.  Notwithstanding  anything to the
contrary  herein,  failure  by  Sellers to  deliver  the  Consents  (hereinafter
defined)  shall not be  considered in the  calculation  of the 20% threshold set
forth above.

          (d) Defect Definition.  For the purpose of this Agreement,  a "Defect"
shall be defined as:

               (1) Any encumbrance,  lien, mortgage, breach of representation or
warranty,  production  payment,  pledge,  claim,  charge,  call  on  production,
default,  defect,  unleased mineral interest,  preferential right or requirement
for consent to assignment affecting the Property,  except for Consents which are
not to be unreasonably withheld or are normally obtained after Closing; or

               (2) A Seller's  NRI in any Property is less than the NRI for such
Property which is set forth in Exhibit "A", or a Seller's gross working interest
("GWI") in any  Property is greater than the working  interest  shown in Exhibit
"A" without a corresponding increase in the NRI in such Property.

          (e) Other Property Information. If, based upon Purchaser's examination
of the Records  pursuant to Section 5(b) above,  Purchaser  shall determine that
any information, statement

                                        6





or data contained in any  information,  reports,  statement or data furnished to
Purchaser  or used in its  economic  analysis  of the  Property  is not  true or
correct in any material  respect,  upon  discovery of any incorrect  information
Purchaser may give written notice to Sellers of such inaccuracy or misstatement.
Any such notice must be provided  during the Review  Period or it will be deemed
to be  waived.  Such  notice  shall  provide a  summary  of such  inaccuracy  or
misstatement.  Upon receipt of such notice,  Sellers shall have the option,  but
not the obligation, to (a) cure or remedy such inaccuracy or misstatement to the
satisfaction  of  Purchaser;  or (b) agree with  Purchaser on a reduction to the
Purchase Price which  reduction  shall reflect  Purchaser's  cost to remedy such
inaccuracy or misstatement. If the inaccuracy or misstatement cannot be cured or
remedied  to  Purchaser's  satisfaction  and if  agreement  cannot be reached on
reduction to the Purchase  Price,  then the affected  Property shall be excluded
from the Property to be acquired by Purchaser  hereunder and the Purchase  Price
shall be  reduced  according  to the  value of the  affected  Property  (or that
portion of such  Property so  affected) as set forth in Schedule 2. In the event
the parties fail to agree upon the implementation of either subclause (a) or (b)
prior to Closing,  and if a  reduction  of more than 20% in the  Purchase  Price
results from the exclusion by Purchaser of the affected Property,  Purchaser may
terminate this Agreement by delivery of written notice so indicating to Sellers,
in which event this Agreement shall terminate, and the parties hereto shall have
no further rights or obligations under this Agreement.

          (f) Casualty Loss. If prior to Closing,  any Property is substantially
damaged or  destroyed by fire or other  casualty  ("Casualty  Defect"),  Sellers
shall notify Purchaser promptly after Sellers learn of such event. Sellers shall
have the right,  but not the  obligation,  to cure any such  Casualty  Defect by
repairing  such  damage  or,  in the  case of  personal  property  or  fixtures,
replacing the property affected thereby with equivalent items, no later than the
date of Closing. If any Casualty Defects exist at Closing, Purchaser may proceed
to purchase  the Property  affected  thereby,  and the  Purchase  Price shall be
reduced by the  aggregate  reduction in the value of such Property on account of
such Casualty Defects,  as determined by the mutual agreement of the parties, or
if the parties are unable to agree on such  amount  prior to Closing,  then such
determination  shall be made by an  appraiser  chosen by the parties  (acting in
good  faith)  and   knowledgeable   in  the  field  to  determine   such  value.
Notwithstanding  anything to the contrary  contained  herein,  Sellers  shall be
entitled to retain all  insurance  proceeds and claims  against other parties in
respect of any such  Casualty  Defect which  occurs  prior to Closing  unless no
reduction is made in the Purchase Price as a result of such Casualty Defect,  in
which event  Purchaser  shall be entitled to the  insurance  proceeds and claims
against other parties arising from such Casualty Defect;  provided,  however, if
in the sole opinion of Purchaser,  any Casualty Defect  materially and adversely
affects the value of the Assets as a whole,  then  Purchaser may terminate  this
Agreement.

     6. Sellers' Representations, Warranties and Covenants. Sellers jointly
and severally represent, warrant and covenant to Purchaser that:

delivered by each Seller shall have been duly executed and delivered at Closing,
and the execution, delivery and performance of this Agreement by such Seller and
the  consummation  of  transactions  contemplated  hereby will not  constitute a
breach of, an event of default  under,  a violation  of, or a conflict  with any
agreement  or other  instrument  to which such Seller is a party  (except to the
extent such instrument may be released at the Closing),  nor will the same cause

or governmental agency having jurisdiction;

          (c) The Wells  (other  than Ship Shoal 69) are  currently  operated by

Property or the  Production  or the receipt of  proceeds  therefrom,  which have
become due and payable  prior to the date hereof  with  respect to the  Property
have  been  properly  paid,  and  Sellers'  allocable  share of such  taxes  and
assessments  which become due and payable prior to the Closing shall be properly
paid by Sellers;

          (e) No Seller has incurred any liability, contingent or otherwise, for
brokers' or finders'  fees in respect of this  transaction  for which  Purchaser

          (g) To the best of each  Seller's  information  and belief,  all laws,
regulations and orders of all governmental agencies having jurisdiction over the
Property have been and shall continue to be complied with until the Closing;

          (h) There are no first  rights of refusal,  consents,  authorizations,
preferential  rights,  options,  or  claims of a similar  nature  affecting  the
Property, other than those listed on Exhibit "C" (the "Consents");


                                        8





          (i) Sellers  shall,  upon  request,  subrogate  Purchaser to any claim
which Sellers may have against any third party, prior owner,  vendor or assignor
with  respect  to the  Property,  or the title  thereto  for  periods  after the
Effective Date;

jurisdiction over the Property;

          (dd) To the best of each Seller's information and belief, there are no

action on behalf of any  governmental  agency  or third  party,  against  either
Purchaser or any Seller; and

          All the information, statistics, summaries and other data furnished by

"Information")  are  furnished  or  will be  furnished  for  Purchaser's  use at
Purchaser's  sole risk. All Information has been compiled or prepared by Sellers
based on their files and records and the  Information is believed to be correct,
but except as otherwise provided herein, Sellers make no representation, express
or implied, as to the accuracy, correctness, completeness or the adequacy of the
Information  and do  not  warrant  or  guarantee  the  Information  in any  way.
Purchaser shall be responsible  for making such  independent  investigation  and
evaluation of the Properties as Purchaser shall deem appropriate, realizing that
Sellers  assume no  liability  to  Purchaser or any other party for any reliance
which  may  be  placed  on  the  Information  or  any  statements  made  herein.

entitled  to seek  adjustment  to the  Purchase  Price for any  inaccuracies  or
omissions relating to the Information that Purchaser discovers during the Review

          Sellers  will  convey  the  Property   with  full   substitution   and
subrogation  in and to all rights and actions of warranty  that  Sellers have or
may have against all preceding owners and sellers of the Property.  Sellers make
no representation or warranty as to the quality,  marketability or environmental
condition of the wells,  fixtures,  facilities,  equipment,  lines and materials
located on the  Properties,  and the same are to be sold on an "as is, where is"
basis and  condition.  SELLERS MAKE NO WARRANTY,  EXPRESS OR IMPLIED,  AS TO THE
MERCHANTABILITY OR FITNESS FOR USE OF SUCH EQUIPMENT AND OTHER PERSONAL PROPERTY
LOCATED ON OR INCLUDED IN THE PROPERTIES.

     The provisions of this Section 6 shall survive  Closing for a period of two

approved by all necessary  corporate action and for which no further approval or
consent is required;

          (b)  The  consummation  of  the  transactions   contemplated  by  this

applicable to Purchaser as a party in interest with respect thereto; and

          (c) This  Agreement  has been duly executed and delivered on behalf of
Purchaser,  and at the Closing, all documents and instruments required hereunder

agency which might  result in  impairment  or loss of value as to such  Seller's
title  to any  part of the  Property  (other  than  normally  encountered  title
disputes which are not, as to the Property  involved,  material and which do not
represent serious threats to the loss of title); or (b) which seeks to restrain;
enjoin or otherwise  prohibit the consummation of the transactions  contemplated

                                       13





after being sent by Federal  Express or Certified  Mail to Sellers or Purchaser,

or such other address as Purchaser or Sellers may, from time to time,  designate
pursuant to the terms hereof.  A facsimile  transmission  shall be considered an
original document for purposes of providing notice under this section.

     12.  Furnishing  Data and  Information.  Sellers  also  agree  to  promptly
cooperate in providing  all Records  necessary  for Purchaser to conduct its due
diligence  under  the  terms of this  Agreement.  For a period of five (5) years
following  the  Closing,  Purchaser  shall allow  Sellers  access to the Records
during normal business hours of Purchaser,  and Sellers shall have the right, at
their own expense,  to make copies thereof.  In addition,  for a period of three
(3) years following the Closing,  Purchaser shall provide Sellers access to well
data for new wells drilled by Purchaser on the Leases.

     13. Post-Closing Adjustments.  As soon as practicable after the Closing and
in any event within 60 days after Closing,  Sellers shall prepare and deliver to
Purchaser,  in accordance  with this Agreement and GAAP, a statement (the "Final
Settlement  Statement")  setting forth each  adjustment  or payment  pursuant to
Section 4 hereof  that was not  finally  determined  as of the  Closing  ("Post-
Closing   Adjustments")   and  showing  the  calculation  of  such  Post-Closing
Adjustments  and the aggregate  amount  thereof.  Within ten business days after
receipt of the Final Settlement Statement,  Purchaser shall deliver to Sellers a
written report  containing  any changes that  Purchaser  proposes be made to the
Final Settlement  Statement.  The parties undertake to agree with respect to the
amounts of such Post-Closing Adjustments no later than 90 days after the Closing
Date.  The date upon which such agreement is reached or upon which the aggregate
amount of the  adjustments  are finally  established  shall be herein called the
"Final Settlement Date". Sellers shall pay to Purchaser,  or Purchaser shall pay
to Sellers,  as the case may be,  within five (5) business  days after the Final
Settlement  Date the amount of such  adjustments  (as finally  established),  by
means of wire transfer in immediately available funds or by means of bank check.

     14. Failure To Perform.  If Sellers should fail to fully and timely perform
any of their obligations hereunder, or should fail to consummate the sale of the
Property,  except due to the Purchaser's default,  Purchaser may, at its option,
enforce specific  performance of this Agreement,  bring suit for damages against
the Sellers, or terminate this Agreement.  If Purchaser should fail to fully and
timely  perform any of its  obligations  hereunder,  and fail to consummate  the
purchase of the

                                       14





Property,  except  due to any  Seller's  default  or  other  provisions  in this
Agreement  that permit  Purchaser to terminate this  Agreement,  Sellers may, at
their option,  enforce  specific  performance of this Agreement,  bring suit for
damages against Purchaser, or terminate this Agreement.

     15. Termination.

          (a) This  Agreement  may be  terminated at any time at or prior to the
Closing:

               (1) by mutual written  consent of Purchaser and the Selling Group
Representative;

               (2) by  Purchaser  on the date of Closing if the  conditions  set
forth in Section 8 have not been  satisfied in all respects by Sellers or waived
by Purchaser in writing by the Closing;

               (3) by  Purchaser  or the  Selling  Group  Representative  if the
Closing  shall not have  occurred  on or before  December  22,  1997;  provided,
however,  that no party hereto can so terminate  this Agreement if such party is
at such time in material breach of any provision of this Agreement;

               (4) by any party if any governmental  authority shall have issued
an order,  judgment or decree or taken any other action  challenging,  delaying,
restraining,  enjoining,  prohibiting or invalidating the consummation of any of
the transactions contemplated herein; and

               (5) by Purchaser if the aggregate  amount of all  adjustments  to
the Purchase Price for Defects exceeds 20% of the Purchase Price.

          (b) In the event that  Closing does not occur as a result of any party
exercising its right to terminate pursuant to Section 15(a), then this Agreement
shall be null and void and no party shall have any rights or  obligations  under
this  Agreement,  except that nothing  herein  shall  relieve any party from any
liability for any breach hereof.

     16. Indemnification by Sellers.

          (a) Sellers agree to jointly and severally indemnify and save and hold
harmless  Purchaser  against and from, any loss,  damage or expense sustained by
Purchaser  arising out of or  resulting  from any breach of any of any  Seller's
representations and warranties made hereunder and not waived by Purchaser.

          (b) Sellers agree to jointly and severally indemnify and save and hold
harmless Purchaser against all claims,  liabilities,  costs, expenses,  windfall

Property,  and based upon the occurrence of events or the accrual of obligations
or liabilities prior to Closing.

          (c) If any claims for brokerage fees are asserted against Purchaser in
connection with this transaction based upon alleged  commitments made by Seller,
Seller shall indemnify

                                       15





Purchaser  against all such claims and reimburse  Purchaser  for all  reasonable
expenses incurred in responding to such claims,  including reasonable attorney's
fees.

          (d) Notwithstanding anything to the contrary contained herein, Sellers
shall  not be  required  to  indemnify  Purchaser  for  matters  resulting  from
Purchaser's own gross negligence or willful misconduct.

          (e) The provisions of this Section 16 shall survive Closing.

     17. Indemnification by Purchaser.

          (a) Purchaser  agrees to indemnify and save and hold harmless  Sellers
against and from, any loss,  damage or expense  sustained by Sellers arising out
of or  resulting  from any  breach  of any of  Purchaser's  representations  and
warranties made hereunder and not waived by Sellers.

          (b) Purchaser shall assume and hereby agrees to pay, honor,  discharge
and  perform  fully  and  timely,  the  obligations  and  liabilities   directly
associated with each Seller's  interest in the Property,  which are attributable
to the period of time from and after the Closing.

          (c) Purchaser  agrees to indemnify and save and hold harmless  Sellers
against all claims,  costs,  expenses,  windfall  profits taxes and  liabilities
arising out of the  ownership  or  operation  of the Property and based upon the
occurrence of events, the accrual of obligations or liabilities or the existence
of conditions on and subsequent to the Closing (but not including those incurred
with  respect to the purchase of each  Seller's  interest in the Property or the
negotiations leading to such purchase).

          (d) If any claims for brokerage fees are asserted  against  Sellers in
connection  with  this  transaction  based  upon  alleged  commitments  made  by
Purchaser,  Purchaser  shall  indemnify  Seller  against  all  such  claims  and
reimburse  Sellers for all  reasonable  expenses  incurred in responding to such
claims, including reasonable attorney's fees.

          (e) Purchaser  agrees to indemify and save and hold  harmless  Sellers
for any  losses  they may incur  resulting  from  Purchaser's  operation  of the
Properties after the date of Closing,  notwithstanding that Purchaser is not the
operator of record.

          (f)  Notwithstanding   anything  to  the  contrary  contained  herein,
Purchaser shall not be required to indemnify  Sellers for matters resulting from
a Seller's own gross negligence or willful misconduct.

          (g) The provisions of this Section 17 shall survive Closing.

     18.  Environmental  Matters.  The Properties  have been used for exploring,
developing  and producing  oil and gas.  Spills of wastes,  crude oil,  produced
water,  hazardous substances,  and other materials may have occurred in the past
on the lease or in connection with the Properties.  There is a possibility  that
there are currently unknown, abandoned wells, plugged wells, pipelines and other
equipment on or  underneath  the  Properties.  It is the intent of Purchaser and
Sellers that all

                                       16





liability associated with the above matters, as well as any liability to plug or
replug such wells in  accordance  with the  applicable  rules,  regulations  and
requirements of governmental agencies be passed to Purchaser at Closing and that
Purchaser  shall assume all  liability  for such matters and all claims  related
thereto, except in all instances for matters resulting from a Seller's own gross
negligence  or willful  misconduct.  Additionally,  the  Properties  may contain
asbestos,  hazardous  substances,  or Naturally Occurring  Radioactive  Material
("NORM"). NORM may affix or attach itself to the inside of wells, materials, and
equipment as scale or in other forms; wells,  materials and equipment located on
the lease or included in the Properties  may contain NORM;  and NORM  containing
material  may have been buried or otherwise  disposed of on the Leases.  Special
procedures may be required for remediating, removing, transporting and disposing
of asbestos, NORM, hazardous substances and other materials from the Properties,
and Purchaser  assumes all liability for any assessment,  remediation,  removal,
transportation,  and disposal of these  materials and  associated  activities in
accordance  with  the  applicable   rules,   regulations  and   requirements  of
governmental agencies.  Notwithstanding the foregoing,  Sellers acknowledge that
Purchaser  shall be entitled to seek  adjustment  to the Purchase  Price for any
environmental  matters,  including  NORM,  that  could  result in  liability  to
Purchaser that Purchaser discovers during the Review Period.

     19. Like-Kind  Exchange.  Each Seller shall have the right to designate the
sale of any of its respective  interest in the Properties as a  non-simultaneous
like-kind  exchange under Section 1031 of the Internal  Revenue Code of 1986, as
amended. Each Seller reserve the right to assign its rights under this Agreement
to a qualified  intermediary in order to effect a like-kind exchange.  Purchaser
agrees to cooperate in the transfer of funds to effect this exchange;  provided,
however, that Sellers hereby agree to indemnify and hold Purchaser harmless from
any and all liabilities,  costs,  claims or damages  resulting from the exchange
and each Seller  acknowledges that any assignment of its rights pursuant to this
Section 19 shall not relieve it of any of its  obligations  to  Purchaser  under
this Agreement. Sellers acknowledge that Purchaser makes no representation as to
the tax  consequences  of such  like-kind  exchange  and that  such  Seller  has
consulted its own tax counsel regarding the same.

     20. Seller Utilization of Production Facilities. Sellers reserve the right,
upon mutual  agreement  with  Purchaser,  to have access to and utilize  certain
existing  platform  space,  pipeline  capacity  and  processing  equipment  (the
"Production  Facilities") which Sellers are conveying to Purchaser hereunder. If
Sellers and  Purchaser  cannot  mutually  agree,  the  parties  agree to allow a
facilities  design engineer who is familiar with the Production  Facilities from
Eagle Consulting,  LLC of Gibson,  Louisiana to determine if Sellers' request to
utilize the Production Facilities can be accommodated by Purchaser without undue
adverse  impact upon  Purchaser's  operations.  Said  utilization  of Production
Facilities  will be charged at Purchase's  cost to Sellers.  Purchaser  will not
charge Sellers any platform boarding, space utilization, throughput, processing,
tariffs  or any  other  fees  or  costs.  Sellers  will be  responsible  for all
construction  costs,  equipment  costs and  Production  Facility  tie-in  costs.
Purchaser also agrees to provide lease operating  (pumping) services at its cost
for Sellers'  wells which may be utilizing the  Production  Facilities.  Sellers
anticipate that they may utilize the Production  Facilities at Sellers' platform
located in South Pelto Block 1 and may need to utilize the Caillou  Boca central
facility water handling facilities and tie-in to a gas sales pipeline connecting
to Texas Gas Transmission  metering platform station No. 0667M. Sellers agree to
indemnify Purchaser for all losses and liabilities  Purchaser may incur pursuant
to Sellers' utilization of the Production Facilities.

     21. Selling Group Representative.  Each Seller hereby authorizes Bois D'Arc
(the "Selling Group  Representative")  to make and receive payments hereunder on
behalf of such  Seller,  to give and  receive  notices on behalf of such  Seller
hereunder (and promptly send copies of any notice to each affected  Seller),  to
agree upon any adjustments to the Purchase Price  hereunder  consistent with the
terms of this Agreement on behalf of such Seller,  to agree to any extensions of
the  Closing  Date on behalf of such  Seller  and to  otherwise  take such other
actions on behalf of such Seller as may be  necessary or desirable to effect the
transactions  contemplated  hereby.  Purchaser  may  rely  upon  any  instrument
executed or other action taken by the Seller Group  Representative  on behalf of
Sellers pursuant to this Section 19 to the same extent as if such instrument had
been executed or action had been taken by each Seller.

     22. Miscellaneous.

          (a) If any term or provision of this  Agreement is held to be illegal,
invalid or  unenforceable,  the  legality,  validity and  enforceability  of the
remaining terms and provisions of this Agreement shall not be affected  thereby,
and in lieu of each such  illegal,  invalid or  unenforceable  term or provision
there  shall  be added  automatically  to this  Agreement  a  legal,  valid  and
enforceable  term or  provision  as similar as possible to the term or provision
declared illegal, invalid or unenforceable.

          (b)  Either  Sellers  or  Purchaser  shall have the right to waive any
requirement  contained  in this  Agreement,  which is  intended  for the waiving
party's benefit,  but except as otherwise  specifically  provided  herein,  such
waiver shall be effective only if in writing and executed by the party for whose
benefit such requirement is intended;  provided,  however,  that any such waiver
shall not be construed as a waiver of any other benefit  accruing to the waiving
party hereunder.

          (c) The  captions  used in  connection  with  this  Agreement  are for
convenience  only and shall not be deemed to expand or limit the  meaning of the
language of this Agreement.

          (d)  Words  of any  gender  used in this  Agreement  shall be held and
construed to include any other gender,  and words in the singular  shall be held
to include the plural, unless the context otherwise requires.

          (e)  Any  proposed  press  releases  pertaining  to  the  transactions
contemplated  hereby shall be approved by both parties prior to the  publication
of such press release; however, such approval shall not be unreasonably withheld
by either of the parties.  Notwithstanding the foregoing,  either party shall be
permitted to make such public  disclosures  pertaining  to this matter as may be
required,  in the reasonable  opinion of counsel for such party,  to comply with
applicable state and federal securities laws.

          (f) Sellers agree that, on or before the Closing,  they will not carry
on any  negotiations  with any  third  party,  for the sale or  transfer  of the
Property, without the prior written consent of Purchaser.

          (g) This  Agreement and all of the  transactions  contemplated  herein
shall be governed by and construed in  accordance  with the laws of the State of
Louisiana.


                                       18





          (h) This Agreement  embodies the entire agreement  between Sellers and
Purchaser  with respect to the subject  matter hereof and  supersedes  all prior
agreements, whether written or oral.

          (i) Except as otherwise  specifically  provided herein, this Agreement
may not be amended  except by an  agreement  in writing  executed by Sellers and
Purchaser.

          (j) This  Agreement  shall be binding upon and inure to the benefit of
Sellers and Purchaser and their respective legal representatives, successors and
assigns. It is expressly understood and agreed that Purchaser's rights hereunder
are freely assignable,  and the term "Purchaser" as used in this Agreement shall
mean and include Purchaser's successors and assigns.

          (k) This Agreement may be executed in any number of counterparts, each
of which shall be deemed to be an original,  and all of which shall be deemed to
be one and the same instrument.

          (l) In addition to the acts and deeds recited herein and  contemplated
to be performed,  Sellers and Purchaser hereby agree to perform,  execute and/or
deliver at and after Closing any and all such further acts, deeds and assurances
as may be reasonably  required to consummate the  transactions  contemplated  by
this Agreement.

          (m) This  Agreement  may be  executed  in  counterpart  by each of the
parties  hereto  as if  each  had  executed  the  same  copy  hereof,  and  each
counterpart, when fully executed, shall constitute an original for all purposes.

          (n) It is  understood  and agreed that in the event any of the working
interest  owners  of the  Properties  do not join in the sale of the  Properties
pursuant to this  Agreement,  but such working  interest  owners within four (4)
months  following the date of Closing sell or  contractually  agree to sell (and
such  sale  is  thereafter  consummated)  to  Purchaser  their  interest  in the
Properties for a greater price than paid to Sellers hereunder,  Purchaser agrees
to pay  Sellers  hereunder  the  difference  between  the price  paid to Sellers
hereunder and the price paid to such working interest owners subsequently.

          (o) In the event Purchaser  charges a third party a tariff,  charge or
other fee ("Transportation Fees") for use of the La Cuisine pipeline, La Cuisine
shall be entitled to 45% of all Transportation Fees received by Purchaser.
