                            THE INTERCOAST ENTITIES
 
                     NOTES TO COMBINED FINANCIAL STATEMENTS
 
1.  ACCOUNTING POLICIES
 
  Corporate Structure
 
     InterCoast Oil and Gas Company (InterCoast Oil and Gas, formerly Medallion
Production Company), a Delaware corporation, and InterCoast Gas Services
Company, a Delaware corporation, (InterCoast Gas Services -- Delaware) are
wholly-owned subsidiaries of InterCoast Energy Company (InterCoast Energy).
InterCoast Gas Services Company, an Oklahoma corporation, (InterCoast Gas
Services -- Oklahoma) and GED Energy Services, Inc., a Delaware corporation,
(GED) are wholly-owned subsidiaries of InterCoast Gas Services -- Delaware.
InterCoast Energy is a wholly-owned subsidiary of MidAmerican Capital Company
(MidAmerican Capital), which is wholly-owned by MidAmerican Energy Company
(MidAmerican Energy).
 
     InterCoast Oil and Gas is primarily engaged in the acquisition,
development, exploration and production of natural gas and oil. InterCoast Gas
Services -- Oklahoma and GED are primarily engaged in the marketing of natural
gas.
 
  Basis of Presentation
 
     The accompanying financial statements reflect the combined operations of
InterCoast Oil and Gas, InterCoast Gas Services -- Oklahoma and GED
(collectively, the InterCoast Entities). The financial statements are presented
on a combined historical cost basis because the InterCoast Entities are under
common control and because InterCoast Energy and its wholly-owned subsidiary,
InterCoast Gas Services -- Delaware, have signed letters of intent to sell the
stock of the InterCoast Entities to KCS Energy, Inc. (see Note 10).
 
     InterCoast Gas Services -- Delaware formed GED and acquired the assets of
GED Gas Services, L.L.C. effective November 1, 1995. The accompanying combined
financial statements include the results of GED for the period since the date of
such acquisition.
 
     Intercompany and affiliated company accounts and transactions have been
eliminated in the combination. Since there is no parent-subsidiary relationship
between the InterCoast Entities, there is no basis for eliminating the equity
accounts of any of the entities.
 
     The preparation of the financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reported period. Actual
results may differ from those estimates.
 
  Oil and Gas Properties
 
     The InterCoast Entities account for their gas and oil properties using the
full cost method of accounting which provides for the capitalization of all
acquisition, exploration and development costs incurred for the purpose of
finding natural gas and oil reserves. The unamortized cost of gas and oil
properties, including estimated future development and abandonment costs, is
amortized using the unit-of-production method based on the ratio of volumes
produced to proved reserves.
 
     Unevaluated properties and associated costs not currently being amortized
and included in oil and gas properties were $1.5 million, $1.6 million and $2.1
million at December 31, 1993, 1994 and 1995, respectively and $3.3 million at
September 30, 1996. Such costs relate to projects which were at such dates
undergoing exploration or development activities or in which the InterCoast
Entities intend to commence such activities in the future. The InterCoast
Entities will begin to amortize these costs when proved reserves are established
or impairment is determined.
 
                                        7

                            THE INTERCOAST ENTITIES
 
             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
     The InterCoast Entities' unamortized costs of gas and oil properties are
limited to the sum of the future net revenues attributable to proved oil and gas
reserves discounted at ten percent plus the cost of any unproved properties. If
the InterCoast Entities' unamortized costs in oil and gas properties exceed this
ceiling amount, a provision for additional depreciation, depletion and
amortization is required. At December 31, 1993, 1994 and 1995 and September 30,
1996, the InterCoast Entities' unamortized costs of oil and gas properties did
not exceed such ceiling amount.
 
     Proceeds from the sale of oil and gas properties are applied to reduce the
costs in the full cost pool unless the sale involves a significant quantity of
reserves in relation to the cost center, in which case a gain or loss would be
recognized.
 
     The InterCoast Entities conduct certain of their drilling activities
(Programs), on a joint venture basis, together with working interest
participants. The agreements under which these investors participate provide the
InterCoast Entities with certain reversionary interests in the properties in the
Programs and current reimbursement of proportionate amounts of overhead and
seismic costs. Overhead reimbursements are included in the Combined Statements
of Income as a reduction of general and administrative expenses. The amounts of
such reimbursements were $872,000, $1,520,000 and $2,047,000 for the years ended
December 31, 1993, 1994 and 1995, respectively, and were $2,022,000 and
$2,653,000 for the nine months ended September 30, 1995 and 1996, respectively.
 
  Production Imbalances
 
     Joint interest owners may take more or less than their ownership interest
of natural gas volumes from jointly owned reservoirs. The InterCoast Entities
follow the sales method of accounting for imbalances, whereby they recognize
revenues based on the actual volumes of natural gas sold to purchasers. The
InterCoast Entities record a liability if sales of natural gas volumes in excess
of their entitlements from a jointly owned reservoir exceed their interest in
the remaining estimated natural gas reserves of such reservoir. Volumetric
production is monitored to minimize imbalances, and such imbalances were not
significant at December 31, 1993, 1994 and 1995 and September 30, 1996.
 
  Amortization of Goodwill
 
     Goodwill was recognized with the acquisition of operating rights, certain
other assets and personnel of Medallion Petroleum, Inc. in 1992 by InterCoast
Oil and Gas and with the acquisition of certain assets and personnel of GED Gas
Services, L.L.C. in 1995 by GED. Goodwill is amortized over the expected period
of benefit of forty years using the straight line method. The unamortized
balance of goodwill included on the Combined Balance Sheets as Intangible and
Other Assets at December 31, 1994 and 1995 and September 30, 1996 is $1,829,000,
$3,486,000 and $3,417,000, respectively.
 
  Long-Lived Assets
 
     In March 1995, the Financial Accounting Standards Board (FASB) issued SFAS
No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to be Disposed Of." This statement, which the InterCoast Entities adopted
on January 1, 1996, requires the InterCoast Entities to review long-lived assets
for impairment whenever circumstances indicate that the carrying amount of an
asset may not be recoverable. Adoption of SFAS No. 121 had no impact on the
InterCoast Entities' results of operations or financial position at the time of
adoption.
 
  Stock-Based Compensation Plans
 
     In October 1995, the FASB issued SFAS No. 123 "Accounting for Stock-Based
Compensation" regarding accounting for stock-based compensation plans. This
statement, which is effective for reporting
 
                                        8

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
periods beginning January 1, 1996, allows for alternative methods of adoption.
The InterCoast Entities do not expect the accounting provisions or the
alternative disclosure provisions of SFAS No. 123 to have a material impact on
the InterCoast Entities' compensation costs.
 
  Accounting for Commodity Price Risk Management
 
     The InterCoast Entities engage in price risk management activities to
minimize the impact of market fluctuations on assets, liabilities, production or
other contractual commitments. Changes in the market value of these transactions
are deferred until the gain or loss on the underlying item is recognized. See
Note 6 for further discussion of the InterCoast Entities' price risk management
activities.
 
  Combined Statements of Cash Flows
 
     For purposes of the Combined Balance Sheets and Combined Statements of Cash
Flows, the InterCoast Entities consider all highly liquid debt instruments
purchased with a remaining maturity of three months or less to be cash
equivalents. There were no material non-cash investing or financing activities
in the years ended December 31, 1993, 1994 or 1995 or in the nine months ended
September 30, 1995 and 1996.

rate of $0.83 and $0.88 for the nine months ended September 30, 1995 and 1996,
respectively.
 
3.  INCOME TAXES
 
     The InterCoast Entities are included in the consolidated federal and, where
appropriate, state income tax returns of MidAmerican Energy. The consolidated
income tax currently payable (or receivable) has been allocated among the
InterCoast Entities and other members of the affiliated income tax reporting
group (Group) based on the respective contributions to the consolidated taxable
income and tax credits of the Group. The InterCoast Entities have received (or
made) payments for the income tax reductions (or increases) contributed to the
Group.
 
     The components of the provision for income taxes are shown below:

4.  RELATED PARTY TRANSACTIONS
 
     The InterCoast Entities receive general and administrative services from
InterCoast Energy, MidAmerican Capital and MidAmerican Energy. The costs of such
services received, including overhead costs, are assigned (and billed) to the
InterCoast Entities. Wages and salaries of the corporate staff and personnel of
InterCoast Energy, MidAmerican Capital and MidAmerican Energy are assigned based
upon an estimate of the time spent by staff and personnel benefitting the
InterCoast Entities. The estimate is reviewed and updated annually. Such wages
and salaries are billed to the InterCoast Entities, along with associated
payroll taxes and the costs of benefits. In addition, certain directly assigned
expenses paid by MidAmerican Capital are billed to the InterCoast Entities.
 
    The InterCoast Entities are parties to guarantee agreements between
InterCoast Energy and its primary lender.

     MidAmerican Capital and InterCoast Energy have entered into letters of
credit and financial guarantees on behalf of the InterCoast Entities to support
certain well costs and the natural gas purchases. Letters of credit and
financial guarantees are conditional commitments issued by MidAmerican Capital
InterCoast Energy to guarantee performance to a third party.
 
     The InterCoast Entities have letters of credit totaling $1,914,000 and
$1,103,000 and financial guarantees amounting to $2,750,000 and $0 which were
not reflected on the Combined Balance Sheets as of December 31, 1995 and 1994,
respectively.
 
     The fair value of the letters of credit was $14,000 and $8,000 at December
31, 1995 and 1994, respectively, estimated based on fees currently charged for
similar agreements. The fair value of the financial guarantees is not
determinable based on the specific characteristics of the guarantees.
 
5.  EMPLOYEE BENEFITS
 
     The InterCoast Entities' employees participate in MidAmerican Energy's
noncontributory defined benefit retirement income plan. Benefits under the plan
are based on participants' compensation, years of service and age at retirement.
Funding is based on the actuarially determined costs of the plan and the
requirements of the Internal Revenue Code and the Employee Retirement Income
Security Act.
 
     As of December 31, 1993, 1994 and 1995, the InterCoast Entities have not
been required to contribute to the plan. Pension costs are allocated to the
InterCoast Entities based on participants' compensation. The

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
amount the InterCoast Entities expensed during 1995, 1994 and 1993 was $12,000,
$44,000 and $0, respectively. The InterCoast Entities' pension accrual included
in the Combined Balance Sheets as Other Current Liabilities was $56,000 at
December 31, 1994 and 1995.
 
6.  FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK
 
  Price Risk Management
 
     The InterCoast Entities have entered into swaps, futures and options to
manage risks associated with fluctuations in the price of natural gas production
and marketing activities.
 
     Commodity Price Swaps.  Commodity price swap agreements require the
InterCoast Entities to make payments to (or entitle it to receive payments from)
the counterparties based upon the differential between a specified fixed and
variable price. The InterCoast Entities account for these transactions on a
settlement basis and, accordingly, gains or losses are included in oil and gas
revenues in the period in which the underlying natural gas is produced. These
agreements do not impose cash margin requirements on the InterCoast Entities or
provide for collateral to the InterCoast Entities. At December 31, 1995,
InterCoast Oil and Gas was party to commodity price swap agreements covering
approximately 8.0 million MMBtu, 6.3 million MMBtu and 23.2 million MMBtu of
natural gas for the years 1996 and 1997 and for the period 1998 through 2005,
respectively.
 
     Futures and Options Contracts.  Natural gas futures require the InterCoast
Entities to buy or sell natural gas at a fixed price. Natural gas options held
to hedge price risk only provide the right, not the requirement, to buy or sell
natural gas at a fixed price. The InterCoast Entities use futures to manage
margins on offsetting fixed-price purchase or sale commitments for physical
quantities of natural gas. The InterCoast Entities use options to limit overall
price risk exposure. Futures contracts mandate initial margin requirements. The
InterCoast Entities maintain such margin accounts and funds in cash any daily
settlement requirements relating to futures contracts.
 
     At December 31, 1995, the InterCoast Entities had futures contracts to
purchase natural gas for approximately 10.1 million MMBtu and to sell natural
gas for approximately 4.9 million MMBtu. The associated unrecognized gain on
futures contracts was $486,000.
 
     Basis Swaps.  Basis swap agreements require the InterCoast Entities to make
payments to (or entitle it to receive payments from) the counterparties based
upon the differential between the variable costs associated with the delivery of
natural gas production to specific delivery points and a contractually specified
fixed cost. At December 31, 1995, InterCoast Oil and Gas had basis swap
arrangements relating to a total of approximately 2.1 million MMbtu during 1996.
 
  Credit Risk
 
     Credit risk relates to the risk of loss that the InterCoast Entities would
incur as a result of the nonperformance by counterparties pursuant to the terms
of their contractual obligations. The InterCoast Entities' overall exposure to
credit risk may be affected positively or negatively in that the counterparties
may be similarly affected by changes in economic, regulatory or other
conditions. The InterCoast Entities maintain credit policies with regard to
counterparties that management believes minimize overall credit risk. With
regard to commodity price and basis swaps, these policies include an evaluation
of potential counterparties' financial condition (including credit rating),
collateral agreements under certain circumstances and the use of standardized
agreements. With regard to futures and options contracts, the InterCoast
Entities utilize New York Mercantile Exchange (NYMEX) contracts. Such contracts
are guaranteed by the NYMEX and, accordingly, have nominal credit risk. As a
result, the InterCoast Entities' risk is limited to the initial purchase price
of the options and to changes in the market value of the futures contracts.
Accordingly, the InterCoast Entities do not anticipate any material impact on
their financial position or results of operations as a result of
 
                                       11

                            THE INTERCOAST ENTITIES
 
             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
nonperformance by counterparties to the financial instruments related to natural
gas production and marketing activities.
 
7.  CONCENTRATION OF CREDIT RISK
 
     Although credit risk is inherent to the foregoing types of financial
instruments and the InterCoast Entities are exposed to losses in the event of
nonperformance by the counterparties, the InterCoast Entities believe that the
aggregate credit risk associated with present swap and hedge arrangements is not
significant due to the nature of the contracts and the counterparties thereto.
 
     The InterCoast Entities' gas and oil production purchasers consist
primarily of independent marketers and major natural gas pipeline companies. The
InterCoast Entities perform credit evaluations of their customers' financial
condition and obtain credit support if the InterCoast Entities believe it is
warranted. The InterCoast Entities have not experienced any significant losses
from uncollectible accounts.
 
8.  COMMITMENTS AND CONTINGENCIES
 
     The InterCoast Entities are lessees in several agreements to lease office
space at various locations. The lease agreements expire in 1999 through 2001,
with various options for renewal. The following is a schedule by year of
estimated future rent expense on such leases as of December 31, 1995:

     On June 19, 1996, an action was brought by Nab Nat. Resources, L.L.C.
against several defendants, including InterCoast Oil and Gas, in the Second
Judicial District Court, Claiborne Parish, State of Louisiana, seeking a
declaration of the court that certain leases and a unit agreement had lapsed by
reason of a cessation of production of oil or gas in paying quantities that
allegedly occurred in the mid 1980s. The plaintiff also seeks, among other
things, an accounting of the production of oil, natural gas and other minerals
from the properties since the alleged lapse of the leases, damages of not less
than $5,000,000 for restoration and clean up of the lands covered by the leases
and certain other damages for trespass and mental anguish. InterCoast Oil and
Gas is in the preliminary stages of investigating the facts on which the lawsuit
appear to be based. Based on InterCoast Oil and Gas' preliminary investigations,
the claim of damages for restoration and clean up of certain lands appears to
relate to properties which the InterCoast Oil and Gas does not own. InterCoast
Oil and Gas currently intends to continue its investigation of the lawsuit and
to defend the action vigorously.
 
9.  SIGNIFICANT ACQUISITION
 
     In April 1996, InterCoast Oil and Gas acquired the interests of Enron Oil &
Gas Company in certain gas and oil properties (the Sawyer Canyon Properties),
associated natural gas gathering lines and other well equipment located in
Texas. The net purchase price at closing was approximately $53.2 million.
InterCoast Oil and Gas concurrently conveyed certain interests in particular
wells to InterCoast Global Management, Inc., a wholly-owned subsidiary of
MidAmerican Capital. InterCoast Oil and Gas retained a production payment on 100
percent of the net proceeds of production from such wells until approximately 80
percent of the estimated

proved developed natural gas reserves attributable to the wells is produced. In
consideration, InterCoast Oil and Gas received from InterCoast Global
Management, Inc. $5.6 million in cash and a promissory note in the amount of
$2.3 million, which is payable in 48 monthly installments over four years and
bears interest at the prime rate. The total adjusted purchase price was $45.2
million. InterCoast Oil and Gas recorded no gain or loss related to this
transaction. The proved reserves associated with the production payment are
included in the InterCoast Entities' estimated net quantities of oil and gas
reserves presented in Note 12.
 
     InterCoast Oil and Gas funded the net purchase price of $45.2 million under
a promissory note due to MidAmerican Capital. This promissory note was due on or
before April 12, 1997, with interest payable quarterly at a floating rate based
on LIBOR plus 55 basis points. The promissory note was repaid in full in July
1996.
 
     The following unaudited pro forma revenues, and net income for the years
ended December 31, 1994 and 1995 and for the three months ended March 31, 1996,
presented below have been prepared assuming the acquisition described above had
been consummated as of January 1, 1994. However, such pro forma information is

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
     In the fourth quarter of 1995, InterCoast Energy acquired certain assets of
GED Gas Services, L.L.C. The acquisition generated natural gas sales revenues of
$15.4 million in such quarter. Additionally, in the fourth quarter of 1995, the
InterCoast Entities' natural gas production volumes and realized natural gas
prices increased resulting in higher oil and gas revenues and income before
income taxes as compared to the prior three quarters of 1995.
 
12.  SUPPLEMENTARY OIL AND GAS DISCLOSURES
 
     Users of the following information should be aware that the process of
estimating quantities of proved and proved developed oil and gas reserves is
very complex, requiring significant subjective decisions in the evaluation of
all available geological, engineering and economic data for each reservoir. The
data for a given reservoir may also change substantially over time as a result
of numerous factors including, but not limited to, additional development
activity, evolving production history and continual reassessment of the
viability of production under varying economic conditions. Consequently,
material revisions to existing reserve estimates occur from time to time.
Although every reasonable effort is made to ensure that reserve estimates
reported represent the most accurate assessment possible, the significance of
the subjective decisions required and variances in available data for various
reservoirs make these estimates generally less precise than other estimates
presented in connection with financial statement disclosures.
 
     Proved reserves are estimated quantities of natural gas, crude oil and
condensate that geological and engineering data demonstrate, with reasonable
certainty, to be recoverable in future years from known reservoirs under
economic and operating conditions existing at the time the estimates were made.
 
     Proved developed reserves are proved reserves that can be expected to be
recovered through wells and equipment in place and under operating methods being
utilized at the time the estimates were made.
 
     Capitalized costs for oil and gas producing activities consist of the

 Standardized Measure of Discounted Future Net Cash Flows Relating to Proved Oil
 and Gas Reserves (Unaudited)
 
     The following information has been developed utilizing procedures
prescribed by Statement of Financial Accounting Standards No. 69 "Disclosures
about Oil and Gas Producing Activities" (SFAS No. 69) and based on oil and gas
reserve and production volumes estimated, in part by the InterCoast Entities,
but primarily by the InterCoast Entities' independent reserve engineers,
Netherland, Sewell and Associates, Inc. It may be useful for certain comparative
purposes, but should not be solely relied upon in evaluating the InterCoast
Entities or their performance. Further, information contained in the following
table should not be considered as representative of realistic assessments of
future cash flows, nor should the Standardized Measure of Discounted Future Net
Cash Flows be viewed as representative of the current value of the InterCoast
Entities.
 
     The InterCoast Entities believe that the following factors should be taken
into account in reviewing the following information: (1) future costs and
selling prices will probably differ from those required to be used in these
calculations; (2) due to future market conditions and governmental regulations,
actual rates of production achieved in future years may vary significantly from
the rate of production assumed in the

calculations; (3) selection of a 10% discount rate is arbitrary and may not be
reasonable as a measure of the relative risk inherent in realizing future net
oil and gas revenues; and (4) future net revenues may be subject to different
rates of income taxation.
 
     Under the Standardized Measure, future cash inflows were estimated by
applying period-end oil and gas prices adjusted for fixed and determinable
escalations to the estimated future production of period-end reserves. As of
December 31, 1995, approximately 37.5 Bcf of gas of the InterCoast Entities'
future production was subject to commodity price swap agreements (see Note 6).
Future cash inflows were reduced by estimated future development, abandonment
and production costs based on period-end costs in order to arrive at future net
cash flow before tax. Future income tax expense has been computed by applying
period-end statutory tax rates to aggregate future pre-tax net cash flows,
reduced by the tax basis of the properties involved and tax carryforwards. Use
of a 10% discount rate is required by SFAS No. 69.
 
     Management does not rely solely upon the following information in making
investment and operating decisions. Such decisions are based upon a wide range
of factors, including estimates of probable as well as possible reserves and
varying price and cost assumptions considered more representative of a range of
possible economic conditions that may be anticipated.
 
     The standardized measure of discounted future net cash flows relating to
proved oil and gas reserves is as follows:

                        PRO FORMA FINANCIAL INFORMATION
 
     The following unaudited pro forma financial information is derived from the
historical financial statements of KCS Energy, Inc. and the statements of the 
InterCoast Entities (Medallion) and the Sawyer Canyon Properties included 
elsewhere in or previously filed with this report.
 
     The unaudited Pro Forma Statement of Consolidated Income for the year ended
December 31, 1995 reflects (i) the Company's Rocky Mountain Acquisition and
Michigan Acquisition, (ii) the sale of the Senior Notes, (iii) the Medallion
Acquisition (which includes Medallion's acquisition of the Sawyer Canyon
Properties in April 1996) and (iv) the sale of the Common Stock offered
pursuant to a Registration Statement on Form S-3 previously filed and the 
application of the estimated net proceeds therefrom as if each transaction had 
occurred on January 1, 1995.
 
     The unaudited Pro Forma Statement of Consolidated Income for the nine
months ended September 30, 1996 reflects the Medallion Acquisition (which
includes Medallion's acquisition of the Sawyer Canyon Properties in April 1996),
the sale of the Common Stock and the application of the estimated net proceeds 
therefrom as if each transaction had occurred on January 1, 1995.
 
     The unaudited Pro Forma Consolidated Balance Sheet as of September 30, 1996
reflects the Medallion Acquisition, the sale of the Common Stock and the 
application of the estimated net proceeds therefrom as if each transaction had 
occurred on September 30, 1996.
 
     The unaudited pro forma financial data should be read in conjunction with
the notes thereto and the Consolidated Financial Statements of the Company
(including the notes thereto) previously filed with the Securities and Exchange
Commission. The unaudited pro forma financial data does not purport to be
indicative of the financial position or results of operations that would
actually have occurred if the transactions described had occurred as presented
in such statements or that may he obtained in the future. In addition, future
results may vary significantly from the results reflected in such statements due
to normal crude oil and gas production declines, changes in prices received for
crude oil and gas, future acquisitions and dispositions of reserves, changes in
estimates of reserves and of the future net revenues therefrom and other
factors.

hereinafter referred to collectively as the "Shares"); and

     WHEREAS, Purchaser desires to purchase the IOG Shares from ICE and the
IGS(OK) Shares and GED Shares from IGS(DE), all upon the terms and conditions
set forth herein;

     NOW, THEREFORE, in consideration of the premises and of the mutual
covenants and agreements, and subject to the terms and conditions, herein
contained, the parties hereto hereby agree as follows:


                                   ARTICLE I.
                          PURCHASE AND SALE OF SHARES


     1.1 Sale and Purchase. ICE hereby agrees to sell to the Purchaser on the
Closing Date (as defined in Section 1.4) all of the IOG Shares, and the
Purchaser hereby agrees to purchase from ICE and pay for all of the IOG Shares
on the Closing Date. IGS(DE) hereby agrees to sell to the Purchaser on the
Closing Date all of the IGS(OK) Shares and the GED Shares, and the Purchaser

<PAGE>   13

certificates in good delivery form and duly endorsed for transfer to the
Purchaser, or accompanied by duly executed stock powers, evidencing all of the
Shares. In exchange, the Purchaser shall deliver to the Shareholders the
consideration set forth in Section manner provided in Section 1.3.

     1.3  Consideration.

          (a) On the Closing Date, the Purchaser shall pay aggregate
     consideration (the "Purchase Price") for the Shares, subject to any
     adjustments to the Purchase Price made pursuant to Sections 1.6, 9.1 and
     9.2, as follows:

               (i) The Purchaser shall pay (by wire transfer of immediately
          available funds to a bank or banks and to an account or accounts
          thereat which the Shareholders shall have specified by written notice
          to the Purchaser at least three (3) Business Days prior to the
          Closing Date) to the Shareholders $209,415,000, to be allocated
          between the Shareholders and in the case of amounts allocated to
          IGS(DE) between the amount paid for the IGS(OK) Shares and the GED
          Shares as the Shareholders shall have specified by written notice to
          the Purchaser at least three (3) Business Days prior to the Closing
          Date; and

               (ii) The Purchaser shall deliver to the Shareholders warrants
          (the "Warrants") substantially in the form of Exhibit A attached
          hereto to purchase 435,000 shares ("Purchaser Shares") of common
          stock, par value $0.01 per share, of the Purchaser ("Purchaser Common
          Stock"), which number of Purchaser Shares and the exercise price
          thereof shall be subject to appropriate adjustment in accordance with
          the terms of the Warrants if such adjustment would be required by
          such terms had such Warrants been issued as of the date hereof, and
          which Warrants shall be allocated between the Shareholders and in the
          case of amounts allocated to IGS(DE) between the amount paid for the
          IGS(OK) Shares and the GED Shares as the Shareholders shall have
          specified by written notice to the Purchaser at least three (3)
          Business Days prior to the Closing Date.

     As used herein, a "Business Day" shall mean a day other than a Saturday,
     Sunday or national legal holiday.

          (b) Any adjustments to the Purchase Price made pursuant to Sections
     1.6, 9.1 and 9.2 shall reduce or increase, as appropriate, the cash
     portion of the Purchase Price payable under Section 1.3(a)(i).

     1.4 Closing Date. Consummation of the transactions contemplated by this
Agreement (the "Closing") shall take place on December 12, 1996, or on the
earliest date thereafter which is the third (3rd) Business Day following the
concurrence by both the Purchaser and the Shareholders (which concurrence shall
not be unreasonably withheld by any party to this Agreement) that all of the
conditions to the Closing (other than delivery of the Shares and of the



                                       2
<PAGE>   14

documents to be delivered at the Closing pursuant hereto and payment of the
Purchase Price) have been satisfied or waived, provided that the parties may
mutually agree in writing to an earlier date (the "Closing Date"). The Closing
shall take place at the offices of counsel for Purchaser's lender in Houston,
Texas, or such other place as the parties hereto shall mutually agree.

     1.5  Purchaser's Additional Deliveries. At the Closing, Purchaser shall
deliver to the Shareholders all of the following: (i) the cash portion of the
Purchase Price as provided in Section 1.3(a)(i), and (ii) the Warrants duly
executed by Purchaser.

     1.6  Intercompany Payables.

          (a) The parties agree that effective immediately prior to the Closing
     all intercompany payables (other than those arising from the purchase or
     sale of oil or gas) owed by any of the Companies or Subsidiary to ICE or
     any of its Affiliates other than any of the Companies or Subsidiary
     ("Intercompany Payables") shall be reclassified as additional paid-in
     capital of the Companies and Subsidiary (the "Reclassification") and that
     from and after the Reclassification, neither ICE nor any of such
     Affiliates shall have any right to collect such amounts from any of the
     Companies or Subsidiary. At Closing, the Shareholders shall deliver to
     Purchaser a copy of the resolutions adopted by the Boards of Directors of
     ICE and each of such Affiliates to which any Intercompany Payables are
     owed, pursuant to which the contribution thereof to the capital of the
     Companies or the Subsidiary has been authorized, which copy shall be
     certified by the respective secretaries of ICE and such Affiliates of ICE
     to be true, correct and in full force and effect as of the Closing.

          (b) The Purchase Price is based in part on the assumption that, and
     the Shareholders agree for purposes of this Agreement that, the total
     equity investment (paid-in capital and retained earnings) in the Companies
     and Subsidiary was $98,443,000 as of the close of business on June 30,
     1996 (the "Equity Investment"). The Purchase Price is also based in part
     on the assumption that the amount of Intercompany Payables (determined as
     set forth below) immediately prior to the Reclassification shall be
     $91,225,000 (the "Threshold Amount"), which the Shareholders agree for
     purposes of this Agreement to be the amount of Intercompany Payables as of
     the close of business on June 30, 1996. Schedule 1.6(b) sets forth the
     Shareholders' calculation of the Threshold Amount and the Equity
     Investment. If the amount of Intercompany Payables immediately prior to
     the Reclassification is greater or less than the Threshold Amount, then
     the Purchase Price shall be adjusted as set forth below, dollar for
     dollar, by the amount of the difference. The amount of Intercompany
     Payables immediately prior to the Reclassification shall be determined
     consistent with practices used in the preparation of the audited financial
     statements of the Companies and Subsidiary as of December 31, 1995, and in
     the same manner as the Threshold Amount was determined including, if
     applicable, among other things, allocations with respect to general and
     administrative expense incurred during the Interim Period solely with
     respect to the Companies or the 


                                       3
<PAGE>   15

     Subsidiary, but excluding any amounts for or with respect to interest or
     corporate overhead. Notwithstanding the preceding sentence, the amount of
     Intercompany Payables immediately prior to the Reclassification (and for
     which an adjustment of the Purchase Price shall be made) shall be (i)
     determined without taking into account the amount of Federal, state and
     local income tax liabilities of the Companies or Subsidiary with respect
     to their taxable income during the Interim Period (and which will be borne
     by Shareholders pursuant to Section 9.3(a)(i) and Section 9.3(a)(iii)) or
     any Federal, state and local income tax benefits or savings with respect
     to the activities of the Companies and Subsidiary during the Interim
     Period which will accrue to the benefit of the Parent or other members of
     the MEC Selling Group as a result of the MEC Selling Group filing a
     consolidated, combined or unitary income tax return with the Companies and
     Subsidiary for the Interim Period, (ii) debited with any amount paid by
     the Companies or Subsidiary to Parent or other member of the MEC Selling
     Group to reflect the Federal, state or local income tax of the Companies
     and Subsidiary attributable to the Interim Period which will be borne by
     Shareholders pursuant to Section 9.3(a)(i) and Section 9.3(a)(iii), (iii)
     credited with any amount paid by Parent or other member of the MEC Selling
     Group to the Companies or Subsidiary to reflect the Federal, state or
     local income tax benefits or savings realized by the MEC Selling Group as
     a result of the activities of the Companies and Subsidiary during the
     Interim Period and (iv) debited with the amount of any payments made by or
     on behalf of the Companies or Subsidiary with respect or relating to the
     initial public offering proposed to be made (but subsequently abandoned)
     by ICE.

          (c) After the Closing, the Shareholders shall prepare or cause to be
     prepared a statement of Intercompany Payables as of the time immediately
     prior to the Reclassification in reasonable detail (the "Closing Date
     Statement"), which the Shareholders shall deliver to Purchaser within 30
     days after the Closing Date.

          (d) Purchaser shall have the opportunity to review the Closing Date
     Statement at Purchaser's expense. Purchaser shall be accorded access for
     this purpose on reasonable notice during business hours to all relevant
     books and records used in the preparation of the Closing Date Statement.
     As promptly as practicable after Purchaser has received the Closing Date
     Statement, but in any event no later than 45 days after receipt, Purchaser
     shall give the Shareholders a written notice which shall either:

               (i)  State that Purchaser accepts the Closing Date Statement; or

               (ii) Describe in reasonable detail, including nature and amount,
          each adjustment (a "Proposed Adjustment") that Purchaser proposes to
          make in the Closing Date Statement. If the Shareholders have not
          received a notice from Purchaser within the 45-day period, Purchaser
          shall be deemed to have accepted the amount of Intercompany Payables
          set forth in the Closing Date Statement.



                                       4
<PAGE>   16

          (e) If Purchaser's notice to the Shareholders includes any Proposed
     Adjustment, then the parties shall negotiate in good faith any
     disagreement as to the propriety of the Proposed Adjustment. If they have
     not resolved all such adjustments within 30 days following the
     Shareholders' receipt of Purchaser's notice, then the parties shall
     jointly select an independent public accounting firm of national
     reputation, other than any accounting firm retained by (i) either of the
     parties to prepare or to review the Closing Date Statement or (ii) either
     of the parties in connection with the audit of their annual financial
     statements, to arbitrate all unresolved Proposed Adjustments. If the
     parties cannot agree on an accounting firm to act as arbitrator, they will
     use a list of all "Big Six" accounting firms that are not disqualified
     from acting as arbitrator, and beginning with the Shareholders, the
     Shareholders (acting jointly) and Purchaser shall each consecutively and
     repeatedly strike one name from the list until only one name remains,
     which shall be the arbitrator. The arbitration shall be conducted in
     Houston, Texas, and shall be limited in scope solely to the unresolved
     Proposed Adjustments set forth in Purchaser's notice. The arbitrator shall
     follow the procedures of the Commercial Arbitration Rules of the American
     Arbitration Association (the "AAA"), but the arbitration shall not be
     administered by the AAA. The parties shall direct the arbitrator to act
     expeditiously to resolve all unresolved Proposed Adjustments. The
     arbitrator's decision shall be final, binding and conclusive on the
     parties and anyone else having an interest in the determination. The
     arbitrator's fees and expenses for conducting the arbitration shall be
     shared equally by the Shareholders, on the one hand, and Purchaser, on the
     other.

          (f)  The "Final Closing Date Statement" shall be either:

               (i) The Closing Date Statement, if accepted or deemed to have
          been accepted by Purchaser in accordance with Section 1.6(d); or

               (ii) The Closing Date Statement adjusted to reflect the
          resolution of any Proposed Adjustments, whether by agreement of the
          parties, or pursuant to the arbitrator's determination in accordance
          with Section 1.6(e).

          (g) Within ten days after the determination of the Final Closing Date
     Statement, the Shareholders shall pay to Purchaser the difference, if
     positive, between the Threshold Amount and the amount of Intercompany
     Payables on the Final Closing Date Statement or Purchaser shall pay to the
     Shareholders the difference, if positive, between the amount of
     Intercompany Payables on the Final Closing Date Statement and the
     Threshold Amount, in either event with interest at the Agreed Rate (as
     hereinafter defined) on the amount of the payment for the period from the
     Closing Date to the date of payment.

          (h) The "Agreed Rate," as used herein, means that annual rate of
     interest from time to time published in the daily issues of The Wall
     Street Journal (the "WSJ") as the Prime Rate under the column presently
     headed "Money Rates" as that base rate of 


                                       5
<PAGE>   17

     interest for corporate loans currently being charged by certain of the
     largest commercial banks in the United States of America. If the WSJ
     should cease to publish an annual rate of interest as the Prime Rate, the
     Agreed Rate for purposes of this Agreement shall be that variable annual
     rate of interest readily ascertainable from reported or published sources
     established by others independent of the party paying such interest which
     such party shall in good faith determine to be the principal equivalent of
     that rate of interest formerly published in the WSJ as the Prime Rate.

          (i) The "Interim Period" as used herein means that period beginning
     at 12:01 a.m. on July 1, 1996 (the "Effective Date") and ending at and
     including the Closing Date.

event creating rights of acceleration, termination or cancellation or a loss of
rights under, or result in the creation or imposition of any encumbrance upon
any of the assets or properties of the Purchaser under (i) the certificate of
incorporation or bylaws of the Purchaser, (ii) any note, instrument, lease,

by which it or its properties are bound, other than such conflicts, violations,
breaches, defaults and events as would not (x) result in any material adverse
change in the assets, business, financial condition or results of operations of
Purchaser, or (y) interfere with the ability of the parties to consummate the
transactions contemplated hereby and to comply with all of the terms and
provisions of the Purchaser Agreements, (iii) any judgment, order, award or
decree of any foreign, federal, Indian, state, local or other court or tribunal

bound, or (iv) any Requirements of Laws affecting the Purchaser or its assets

administrative, arbitration, or other proceeding pending against or affecting
Purchaser, or to the best of Purchaser's knowledge, pending against or
affecting any Affiliate of Purchaser, or to the best of Purchaser's knowledge,

amended, 15 U.S.C. Section 18a ("HSR"), is not required before consummation of
the transactions contemplated hereby; and the Board of Directors of Purchaser

responsible lending institutions, available lines of credit or other sources of
immediately available cash, to enable it to deliver the cash portion of the
Purchase Price at the Closing and to take such other actions as may be required

Purchaser Financial Statements"). The Purchaser Financial Statements were
prepared in accordance with generally accepted accounting principles applied on
a consistent basis during the periods involved; provided, however, that the
Most Recent Purchaser Financial Statements are subject to normal year-end
adjustments and lack footnotes and other presentation items. The Purchaser
Financial Statements fairly present the financial position of the Purchaser as
of the respective dates thereof and the results of its operations, cash flows
and changes in financial position for the periods then ended. As of the
respective dates of the balance sheets included in the Purchaser Financial
Statements, Purchaser had no liabilities or obligations, accrued, absolute,
contingent or otherwise, which were required in accordance with generally
accepted accounting principles consistently applied to be set forth in such
balance sheets (excluding as to the Most Recent Purchaser Financial Statements
matters which would be required by generally accepted accounting principles to
be disclosed in notes thereto) other than those reflected or reserved against
in such balance sheets. Purchaser has no liabilities or obligations, accrued,
absolute, contingent or otherwise, which are required, in accordance with
generally accepted accounting principles consistently applied, to be set forth
in its balance sheet or notes thereto, other than those (x) reflected or
reserved against in the balance sheet included in the Most Recent Purchaser
Financial Statements (excluding matters which 


                                       8
<PAGE>   20

would be required to be disclosed in notes thereto) or (y) incurred in the
ordinary course of business since June 30, 1996. Purchaser shall promptly
provide to the Shareholders a copy of its quarterly report on Form 10-Q for the
fiscal quarter ended September 30, 1996, once the same has been filed with the
Securities and Exchange Commission.

     2.9 Disclosure. The Annual Report and the Quarterly Report did not, as of
their respective dates, contain an untrue statement of a material fact or omit
to state a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances in which they were made, not
misleading.

     nor shall there be any change in the number of shares or classes of the
     capital stock of Purchaser or in the number of shares of its capital stock
     reserved for issuance. Purchaser has not authorized or entered into and
     shall not authorize or enter into any merger, consolidation,
     reorganization, dissolution or other action, agreement or transaction
     which would change its corporate or capital structure. Purchaser has not
     taken any action that would have adjusted, and shall not take any action
     that would adjust, the number of Purchaser Shares covered by the Warrants
     or the exercise price thereof, had the same been issued from and after
     June 30, 1996.

          (c)  No Amendment to Certificate of Incorporation.  Purchaser has not
     amended, and shall not amend, its certificate of incorporation or bylaws.

          (d) Other Changes. Purchaser has not engaged and shall not engage in
     any transactions which in the aggregate would materially and adversely

          as currently conducted (collectively, "Governmental Permits").
          Schedule 3.13(f) lists all previously held Governmental Permits which
          have expired and are being renewed or reissued by the Companies or
          the Subsidiary and all applications for new permits which are pending
          before a Governmental Body, the failure to have renewed or reissued
          would have a material adverse effect on the Property affected
          thereby.

               (ii) Each of the Companies and the Subsidiary has fulfilled and
          performed its respective obligations under each of the Governmental

          Permit, and which would have a material adverse effect on the
          Property affected thereby.

this Agreement have been duly authorized by the board of directors and sole
shareholder of each of the Shareholders; the consummation of the transactions

rights of acceleration, termination or cancellation or a loss of rights under,

bound other than such conflicts, violations, breaches and defaults as would not
(x) result in any material adverse change in the assets, business, financial
condition or results of operations of the Companies and Subsidiary taken as a
whole, or (y) interfere with the ability of the parties to consummate the
transactions contemplated hereby, (iii) any judgment, order, award or decree of
any foreign, federal, Indian, state, local or other court or tribunal or any
award in any arbitration proceeding to which any of the Shareholders, the
Companies or Subsidiary is a party or any of the respective assets or
properties of any of the Shareholders, the Companies or Subsidiary is subject
or by which any of the Shareholders, the Companies or Subsidiary is bound, or
(iv) any Requirements of Laws affecting any of the Shareholders, the Companies
or Subsidiary or their respective assets or properties, assuming
inapplicability of HSR in reliance on Purchaser's representation and warranty
in the last sentence of Section 2.4. Except as otherwise contemplated by
Section 3.14, and subject to the assumption set forth in the prior sentence,
none of the Companies or the Shareholders is required or obligated to make any

licenses or permits from, third Persons, including, without limitation, courts
or governmental authorities, in order to consummate the transactions
contemplated by this Agreement.

     3.17 Insurance. The Companies and Subsidiary have in effect and shall
maintain in effect until the Closing Date the insurance coverage described on
Schedule 3.17 or substantially similar insurance coverage (the "Insurance
Policies"). Such insurance coverage is with reputable insurers and, in respect
of amounts, types and risks insured, is that which the Companies and Subsidiary
believe is customary with businesses of a similar nature and size in accordance
with good business practice, including insurance against loss or damage from
hazards and risks to the Person, rights and properties of others (including
employees of the Companies or Subsidiary), and insurance against loss or damage
to motor vehicles and real property of the Companies or Subsidiary. All of the
Insurance Policies are in full force and effect.

     3.18 Compliance with ERISA. Except as listed in Schedule 3.18, none of the
Companies nor Subsidiary maintains, sponsors, or participates in or is required
to make contributions to any pension, profit sharing, thrift or other
retirement plan, employee stock ownership plan, deferred compensation, stock
ownership, stock purchase, performance share, bonus or other incentive plan,
severance plan, health or group insurance plan, death benefit plan, disability
benefit plan, welfare plan, or other similar plan, agreement, policy or
understanding, whether or not such plan is intended to be qualified under
Section 401(a) of the Code, including without limitation any employee benefit
plan within the meaning of Section 3(3) of the Employee Retirement Income
Security Act of 1974, as amended ("ERISA") (each such plan, agreement, policy
or understanding individually, a "Plan"). The Shareholders have made available
to the 


                                      28
<PAGE>   40

Purchaser true and complete copies of (i) each Plan and any trust agreement
and/or group annuity contract relating to such Plan, (ii) summary plan
description and any summary of material modifications of each Plan (if any such
summary is required), (iii) the three annual reports on Form 5500 most recently
filed with the IRS with respect to each Plan (if any such report was required),
(iv) the most recent IRS determination letter requested for each Plan intended
to meet the requirements of Section 401(a) of the Code, (v) the most recent
actuarial report for each Plan for which an actuarial report is required and
(vi) all related communications with respect to each Plan for the last three
consecutive years prior to the Closing Date with the IRS or U.S. Department of
Labor relating to Plan qualification, filing of required forms or audits.

          (a) Prohibited Transactions. None of the Companies nor Subsidiary has
     engaged in a transaction in connection with which any of the Companies or
     Subsidiary could be subject to (either directly or indirectly) a liability
     for either a civil penalty assessed pursuant to Section 502(i) or (l) of
     ERISA or a tax imposed by Section 4975 of the Code.

          (b) Plan Termination; Liabilities. There has been no termination or
     partial termination of any Plan that would give rise to a liability to the
     Pension Benefit Guaranty Corporation on the part of any of the Companies
     or Subsidiary.

          (c) Accumulated Funding Deficiency. Full payment has been made of all
     amounts which are required by law, collective bargaining or other
     agreement, or under the terms of each Plan to have been paid as
     contributions to such Plan for all periods through the Closing Date
     including a pro rata share of contributions due for the current plan year
     which will have been made by such Closing Date or provided for by adequate
     reserves by the Companies and Subsidiary, and no accumulated funding
     deficiency (as defined in Section 302 of ERISA and Section 412 of the
     Code), whether or not waived, or "liquidity shortfall" (as defined in
     Section 412(m)(5) of the Code) exists with respect to any Plan.

          (d) Relationship of Benefits to Pension Plan Assets. The present
     value of all benefits (whether or not vested) under each of the Plans that
     are described in Section 3(2) of ERISA does not exceed the current fair
     market value of the assets of each such Plan allocable to such accrued
     benefits. For purposes of the representations in this Section 3.18(d), the
     assumptions prescribed by the Pension Benefit Guaranty Corporation for
     valuing plan assets or liabilities upon plan termination shall be applied
     and the term "benefits" shall include the value of all benefits, rights
     and features protected under Section 411(d)(6) of the Code or its
     successors and any ancillary benefits (including disability, shutdown,
     early retirement and welfare benefits) provided under any such Plan and
     all "benefit liabilities" as defined in Section 4001(a)(16) of ERISA.

          (e) Execution of Agreements. The execution and delivery of this
     Agreement and the consummation of the transactions contemplated by this
     Agreement will not 


                                      29
<PAGE>   41

     involve any transaction which is subject to the prohibitions of Section
     406 of ERISA or in connection with which a tax could be imposed pursuant
     to Section 4975 of the Code, and except for agreements identified in
     Schedule 3.18(e) or as expressly provided for in this Agreement, none of
     the Companies nor the Subsidiary is a party to any agreement which (i)
     requires any such organization to make any bonus or severance payment to
     any of its officers or employees solely by reason of the change of control
     of the Companies effected by the sale of the IOG Shares, IGS(OK) Shares or
     GED Shares or (ii) requires it to make a payment to any of its officers or
     employees that, to the knowledge of the Shareholders, may be an "excess
     parachute payment" to a "disqualified individual", as such terms are
     defined in Section 280G of the Code.

          (f) Multiemployer Plans. None of the Companies nor Subsidiary ever
     has had an obligation to contribute to a Multiemployer Plan, as such term
     is defined in ERISA.

          (g) Fiduciary and Other Liability. There have been no acts, failures
     to act, omissions, transactions or pending issues involving a Plan or the
     assets thereof which could result in imposition on any of the Companies or
     Subsidiary (whether direct or indirect) of damages or liability in actions
     brought under Section 502 of ERISA which might reasonably be expected to
     subject the Companies and Subsidiary to the payment of any penalty,
     interest, tax or other obligation that could adversely affect the value of
     the assets and business of any of the Companies or Subsidiary. The
     Companies and the Subsidiary are in full compliance with state law
     requirements for worker's compensation coverage and existing insurance
     contracts are, and as of the Closing will be, fully operative and in
     effect. No claim or action for damages or liability for occupational
     illness or injury to any employee of any of the Companies or Subsidiary
     (based on intentional infliction of injury or otherwise) that would not be
     covered by the insurance contracts described in the next preceding
     sentence has been filed and the Companies and Subsidiary have no knowledge
     of circumstances that would give rise to any such claim against any of the
     Companies or the Subsidiary.

          (h) Compliance with Reporting Requirements and Other Applicable Law.
     Each Plan is in compliance with all applicable reporting, disclosure and
     other requirements of ERISA, the Code and other applicable law as they
     relate to such Plan, including but not limited to timely filing all
     required Forms 5500 (or equivalent annual report) for such Plan.

          (i) No Retiree Plans. Except as provided in Schedule 3.18, none of
     the Companies or the Subsidiary provides post-retirement medical, health,
     disability or death protection coverage or contributes to or maintains any
     Plan which provides for medical, health, disability or death benefit
     coverage following termination of employment by any present or former
     officer, director or employee except as is required by Section 4980B(f) of
     the Code or other applicable statute, nor has it made any representations,
     agreements, covenants or commitments to provide that coverage.



                                      30
<PAGE>   42

          (j) Plan Amendment and Termination. Except as disclosed in Schedule
     3.18, each such Plan (including any such plan covering retirees or other
     former employees) may be amended or terminated without material liability
     (with respect to benefits) to any of the Companies or Subsidiary on or at
     any time after the consummation of the transactions contemplated by this
     Agreement without contravening the terms of such plan, or any law or
     agreement that pertains to any of the Companies or Subsidiary.

          (k) Controlled Group Liabilities. None of the Companies or the
     Subsidiary has or will have any material liability or obligation for
     taxes, penalties, contributions, losses, claims, damages, judgments,
     settlement costs, expenses, costs, or any other liability or liabilities
     of any nature whatsoever arising out of or in any manner relating to any
     Plan, (including but not limited to employee benefit plans such as foreign
     plans which are not subject to ERISA), that has been, or is, contributed
     to by any entity, whether or not incorporated, which is deemed to be under
     common control (as defined in Section 414 of the Code), with any of the
     Companies or the Subsidiary.

     3.19 Oil and Gas Reserves. The Shareholders, IOG and Subsidiary have
furnished the Purchaser estimates of IOG's and Subsidiary's proved oil and gas
reserves as of the dates of the reports described in Schedule 3.19
(collectively, "Reserve Reports"). To Shareholders' knowledge, the information
contained in the Reserve Reports regarding the Properties was reasonable at
such dates and did not contain materially untrue statements of fact or omit to
state material facts which if completely and accurately stated would have had a
net effect upon the estimated net recoverable quantities of oil and gas
reflected in the Reserve Reports sufficient to materially and adversely affect
the assets, business, financial condition or results of operations of the
Companies and Subsidiary taken as a whole. All lease operating expenses
outlined in the Reserve Reports were based upon good faith estimates of such
expenses and are not materially inconsistent with the Companies' and the
Subsidiary's currently existing related contractual obligations and to the
Companies' and the Subsidiary's knowledge, currently existing Requirements of
Laws. The historical Hydrocarbon production information relating to the
Properties listed in the Reserve Reports which was provided by the
Shareholders, the Companies, the Subsidiary and Netherland, Sewell and
Associates, Inc. (and not by other third Persons) to Ryder Scott Company and
used in connection with such company's preparation of evaluations of the Oil
and Gas Properties on behalf of the Purchaser is, insofar as such information

     in Section 1504(a) of the Code), which includes, without limitation, the
     Parent, the Shareholders, the Companies, and Subsidiary. Such "affiliated
     group" of corporations is referred to herein as the "MEC Group." The MEC
     Group without the Companies and Subsidiary is sometimes referred to herein
     as the "MEC Selling Group." Except as disclosed in Schedule 3.21, none of

     the Companies and Subsidiary. All such returns are, or will be, in all
     material respects, correct and complete. All taxes, deficiencies,
     penalties and interest shown by such returns, reports and estimates to be
     payable will have been paid or accrued on the books of the Companies and
     Subsidiary, including all tax assessments and/or levies imposed upon any

     estimates of the MEC Group have been or will be timely filed with the
     Internal Revenue Service for each taxable period ending on or before
     December 31, 1995 (taking into account all extensions permitted by
     applicable law). All such returns are, in all material respects, correct
     and complete. Any amount of such taxes, deficiencies, penalties and

     income tax return and estimates of the MEC Group for the taxable period
     ending December 31, 1996 will be timely filed (taking into account all
     extensions permitted by applicable law) with the Internal Revenue Service,
     and any consolidated, combined or unitary income tax return required to be
     filed by the MEC Group for the taxable period ending December 31, 1996
     will be timely filed (taking into account all extensions permitted by
     applicable law). Such returns will include the income, deductions and
     credits of the Companies and Subsidiary for the period through and
     including the Closing Date, including the amount of taxable income
     resulting from the Section 338(h)(10) Election.

     Companies or Subsidiary or which relate to any of the Companies or
     Subsidiary with respect to any Taxes for any period, (ii) no audit of any
     federal, state or local return of any of the Companies or Subsidiary, or

     audit been requested or given by any taxing authority, (iii) no claims,

     threatened by any taxing authority with respect to any Tax for which
     either of the Companies or Subsidiary may have liability, and (iv) no
     requests for rulings or administrative determinations of any sort relating
     to any Tax are pending between any of the Companies or Subsidiary and any
     taxing authority.

          (f) Except as disclosed on Schedule 3.21, no issue or issues, singly
     or collectively, have been raised (and are currently pending or unsettled)
     by any taxing authority in connection with any returns and reports
     referred to in this Section 3.21 which would, if determined adversely,
     have a material adverse effect on the assets, 


                                      34
<PAGE>   46

     business, financial condition, results of operations or prospects of any
     of the Companies or Subsidiary.

          (g) All material required amounts have been or will be withheld by
     each of the Companies and Subsidiary from its employees and accrued or
     paid over to appropriate governmental authorities for all periods ending
     on or before the Closing Date in full compliance with the tax withholding
     provisions of applicable federal, state and local laws. Proper and
     accurate federal, state and local returns have been or will be filed by or
     on behalf of the Companies and Subsidiary for all periods for returns due
     on or before the Closing Date with respect to income tax withholding,

     and the amounts shown on such returns to be due and payable have been paid
     or will be paid in full or adequate provision therefor has been or will be
     made. To the extent that the employer's portion of such trust fund or
     employer taxes for compensation attributable to the Interim Period is paid
     by Parent, such payments shall result in an increase in the Intercompany
     Payables which will affect the Purchase Price.

          (h) Any and all Tax agreements or arrangements and any and all other
     agreements or arrangements with respect to any Taxes imposed by any taxing
     jurisdiction executed between or agreed to by any of the Companies and/or
     Subsidiary with the Parent or any member of the MEC Selling Group which
     relate to a payment by or to any of the Companies or Subsidiary with
     respect to its Taxes, and which is continuing in effect will be terminated
     without liability to either party and shall be void effective as of the

                                  ARTICLE IX.
          ADDITIONAL AGREEMENTS OF THE PURCHASER AND THE SHAREHOLDERS

     9.1 Adjustments for Title Defects. The procedures to be followed with
respect to Purchaser's assertion of Title Defects, and the adjustment of the
Purchase Price attributable to such Title Defects, shall be as follows:

          (a) Access to Records and Summaries. Promptly after execution of this
     Agreement, Shareholders shall cause the Companies and the Subsidiary to
     provide to Purchaser and its consultants and advisors (i) access at all
     reasonable times to the Companies' and the Subsidiary's accounting, land,
     production, engineering, and other records regarding the Oil and Gas
     Properties for the purpose of reviewing title to the Oil and Gas
     Properties and (ii) reasonable office space in the Companies' and the
     Subsidiary's offices for such review. At Purchaser's request, to the
     extent any such records are in the possession of a co-working interest
     owner, partner or other third party and the Companies or the Subsidiary
     have the right of access thereto, the Companies and the Subsidiary will
     use their reasonable efforts (without being obligated to incur expense) to
     provide Purchaser access to such other records or obtain copies thereof
     for Purchaser's review. As soon as reasonably practicable, but in all
     events prior to the Closing Date, Shareholders shall cause the Companies
     and the Subsidiary to generate and deliver to the Purchaser summaries of
     title and contractual information relating to each of the Significant and
     the Additional Properties, such summaries to contain listings of all of
     the following information: Leases, Lands, Wells and currently-effective
     contracts and agreements (including contracts and agreements included
     within the definition of Permitted Encumbrances and any other contractual
     obligations of which any of the Companies or Subsidiary have knowledge)
     which pertain or apply to each such Significant or Additional Property.



                                      45
<PAGE>   57

          (b) Notice of Asserted Title Defects. Prior to the expiration of the
     period commencing on the execution of this Agreement and ending on the
     first anniversary of the Closing Date (the "Title Examination Period"),
     Purchaser shall furnish to Shareholders written notice specifying in
     reasonable detail each matter which Purchaser in good faith asserts is a
     Title Defect hereunder, together with the Defect Amount estimated in good
     faith by Purchaser for each such asserted Title Defect and a reasonably
     detailed explanation of the computation of and basis for such Defect
     Amount (each such notice, a "Title Defect Notice"). Any Title Defects not
     asserted by Purchaser on or before the expiration of the Title Examination
     Period with respect to any of the Oil and Gas Properties shall be deemed
     conclusively to be Permitted Encumbrances. Furthermore, if (i) on or
     before the second (2nd) Business Day prior to the Closing Date, Purchaser
     has knowledge of the verification of the existence of a Title Defect
     affecting a Significant Property by way of a title opinion or other
     written title report delivered to, or obtained, generated or reviewed by
     Purchaser in connection with its title review conducted pursuant to this
     Section 9.1 and possesses information in such detail as will enable
     Purchaser to furnish Shareholders a Title Defect Notice with respect to
     such Title Defect and (ii) Purchaser fails to assert such Title Defect
     pursuant to this Section 9.1 on or before 5:00 p.m. on the second (2nd)
     Business Day prior to the Closing Date, then such Title Defect shall be
     deemed conclusively to be a Permitted Encumbrance with respect to such
     Property. Anything herein to the contrary notwithstanding, after 5:00 p.m.
     on the second (2nd) Business Day prior to the Closing Date, Purchaser may
     only assert as Title Defects relating to the Significant Properties those
     Title Defects which Purchaser asserts in good faith were created by,
     through or under the Companies, the Subsidiary or any of their Affiliates
     prior to the Closing (including Title Defects which could have been
     asserted but for the failure of any summary delivered by the Companies or
     the Subsidiary pursuant to Section 9.1(a) above to accurately and
     completely set forth (i) the information required to be presented therein,
     and (ii) any contracts, agreements or other contractual obligations
     relating to the Significant Property in question to which such entity is a
     party or under which such entity has obtained an assignment of rights).
     Anything herein to the contrary notwithstanding, after 5:00 p.m. on
     January 31, 1997, Purchaser may only assert as Title Defects relating to
     the Additional Properties those Title Defects which Purchaser asserts in
     good faith were created by, through or under the Companies, the Subsidiary
     or any of their Affiliates prior to the Closing (including Title Defects
     which could have been asserted but for the failure of any summary
     delivered by the Companies or the Subsidiary pursuant to Section 9.1(a)
     above to accurately and completely set forth (i) the information required
     to be presented therein, and (ii) any contracts, agreements or other
     contractual obligations relating to the Additional Property in question to
     which such entity is a party or under which such entity has obtained an
     assignment of rights). Title Defects affecting the Significant and the
     Additional Properties, other than those created by, through or under the
     Companies, the Subsidiary or any of their Affiliates (as referred to in
     the preceding sentence), which Purchaser fails to assert on or prior to
     5:00 p.m. on the second (2nd) Business Day prior to Closing Date or
     January 31, 1997 (as applicable) shall be deemed conclusively to be a
     Permitted Encumbrance with respect to such Property. During the 


                                      46
<PAGE>   58

     portion of the Title Examination Period following the Closing Date,
     Purchaser shall use its reasonable best efforts to furnish Shareholders
     with a Title Defect Notice with respect to a Title Defect promptly after
     Purchaser has knowledge of the verification of the existence of such Title
     Defect and possesses information in such detail as will enable Purchaser
     to furnish Shareholders a Title Defect Notice with respect thereto;
     provided, however, that Purchaser shall not be obligated to furnish
     Shareholders Title Defect Notices more often than every other Tuesday
     during the Title Examination Period. Failure by Purchaser to identify all
     Properties (or to identify all portions of a Property) which are subject
     to a particular Title Defect in a Title Defect Notice shall not prevent
     Purchaser from asserting such Title Defect in separate or subsequent Title
     Defect Notices, subject to otherwise timely asserting such Title Defect
     prior to the expiration of the Title Examination Period or any other
     applicable time period set forth in Section 9.1(b).

          (c) Notice in Response to Purchaser's Notice. Shareholders shall give
     written notice to Purchaser for each Title Defect asserted in a Title
     Defect Notice by Purchaser ("Response Notice") as to whether it (a)
     intends to cure the asserted Title Defect, (b) disagrees with Purchaser's
     assertion that the Title Defect exists, (c) disagrees with the Defect
     Amount estimated by Purchaser for such Title Defect, or (d) takes any
     combination of the foregoing positions. With respect to each Title Defect
     Notice, Shareholders shall give their Response Notice on or before 5:00
     p.m. on the 30th day following the Shareholders' receipt of such Title
     Defect Notice. If Shareholders disagree with Purchaser's assertion of the
     existence of a Title Defect or the Defect Amount with respect thereto,
     Shareholders' Response Notice shall also specify in reasonable detail
     Shareholders' grounds for such disagreement, the Defect Amount estimated
     by Shareholders therefor, or both, as the case may be. Shareholders'
     failure to deliver a timely Response Notice with respect to a Title Defect
     asserted in a Title Defect Notice shall be deemed to be an admission of
     the existence of such Title Defect, acceptance of Purchaser's estimate of
     the Defect Amount with respect thereto and a waiver of Shareholders'
     rights to cure such Title Defect.

          (d) Method of Determination of Defect Amounts. Without limiting
     Shareholders' right to dispute the existence of a Title Defect, Defect
     Amounts for each asserted Title Defect shall be determined as follows (it
     being understood that if a Title Defect is not effective or does not
     affect one of the Companies' or the Subsidiary's title to a Property
     throughout the entire productive life of such Property, such fact shall be
     taken into account in determining the Defect Amount):

               (i) If the Title Defect relates to failure of title to the
          entirety of a Company's or the Subsidiary's title to an Oil and Gas
          Property, the Defect Amount shall be the amount set forth as the
          Value for that Property in Schedule



                                      47
<PAGE>   59

               (ii) If the Title Defect results from a lien, security interest,
          pledge or collateral assignment upon one or more Oil and Gas
          Properties (or a portion thereof) which is liquidated in amount, then
          the Defect Amount shall be the amount necessary to remove such lien,
          security interest, pledge or collateral assignment from a Company's
          or the Subsidiary's title to such Properties (or portion thereof).

               (iii)If the Title Defect results from any of the Companies or
          the Subsidiary having a lesser NRI in an Oil and Gas Property than
          the NRI specified therefor in Schedule 3.6(a), the Defect Amount
          shall be equal to the product obtained by multiplying the Value for
          that Property by a fraction, the numerator of which is the reduction
          in the NRI and the denominator of which is the specified NRI for such
          Property.

               (iv) If the Title Defect results from any matter not described
          in paragraphs (i), (ii), or (iii) above, then the Defect Amount shall
          be a portion of the Value for that Property, said portion to be equal
          to the difference between the Value of a Company's or the
          Subsidiary's title to such Property without such Title Defect and
          with such Title Defect.

     Notwithstanding anything herein to the contrary, the aggregate Defect
     Amounts attributable to Title Defects relating to a Property for which
     Purchaser receives an adjustment in the Purchase Price shall never exceed
     the Value of that Property.

          (e) Shareholders' Pre-Closing Election. In the event Purchaser
     asserts on or before 5:00 p.m. on the second (2nd) Business Day prior to
     the Closing Date one or more Title Defects with respect to any Property,
     then at any time on or before 5:00 p.m. on the Business Day prior to the
     Closing Date, Shareholders may elect to cause the affected Company or
     Subsidiary to convey to either Shareholder, or to an entity designated by
     Shareholders, all of such Property, effective as of the Effective Date;
     provided that Purchaser shall have the right to unconditionally waive any
     asserted Title Defect and any claim against the Shareholders related to
     such Title Defect (a "Title Waiver") at any time prior to such conveyance,
     in which case the Property shall not be conveyed pursuant to Shareholders'
     election. Shareholders shall notify Purchaser in writing of their election
     to cause the affected Company or Subsidiary to convey any such Property on
     or before 5:00 p.m. on the Business Day prior to the Closing Date and if
     Shareholders give such notice, then the Purchase Price shall be reduced by
     the Value of such Property adjusted to reflect the revenues and
     expenditures (including capital expenditures) with respect to such
     Property from and after the Effective Date. If Shareholders make an
     election to cause a Property to be conveyed, then prior to Closing, unless
     Purchaser makes a Title Waiver with respect to such Property, by an
     instrument of assignment or conveyance which is expressly made without any
     warranty or representation, express or implied, as to title, condition or
     any other matter (but, to the extent transferable, with subrogation of
     Shareholders or the designee referred to above 


                                      48
<PAGE>   60

     to all covenants and warranties theretofore made by any of the Companies'
     or the Subsidiary's predecessors in title, except any Affiliates of the
     Companies), the affected Company or Subsidiary shall convey the title, if
     any, which such Company or Subsidiary has in all of such Property to
     either Shareholder (or to an entity designated by Shareholders) as
     Shareholders shall elect.

          (f) Pre-Closing Adjustment for Uncured Title Defects. If on or before
     5:00 p.m. on the Business Day prior to the Closing Date, any Title Defect
     and the Defect Amount as asserted by Purchaser are agreed to by
     Shareholders as to one or more such Title Defects, then the sum of Defect
     Amounts attributable to those Properties (or portions thereof) for which
     Shareholders and Purchaser are in agreement as to both the existence of a
     Title Defect and the Defect Amount, but excluding Properties conveyed to
     either Shareholder (or their designee) pursuant to Section 9.1(e), shall
     be applied to reduce the cash portion of the Purchase Price.

          (g) Resolution or Cure of Title Defects. If Shareholders have
     provided a Response Notice in accordance with Section 9.1(c), then
     Shareholders shall use reasonable efforts to resolve or cure the Title
     Defect in question during the Cure Period. On or before expiration of the
     Cure Period with respect to such Title Defect, Shareholders shall give
     Purchaser written notice of either (i) any curative actions which in
     Shareholders' determination cure or reduce the Defect Amount of a Title
     Defect asserted by Purchaser, including an explanation in reasonable
     detail of any claimed reduction in the Defect Amount, or (ii)
     Shareholders' inability to cure such Title Defect. On or before the
     expiration of thirty (30) days after the end of all Cure Periods
     applicable to Title Defects which Shareholders attempt to resolve or cure
     pursuant to this Section 9.1(g), Purchaser shall provide to Shareholders
     in writing a list of (x) those Title Defects asserted by Purchaser which
     Shareholders claim to have cured and which Purchaser believes have not
     been cured, together with the revisions, if any, in Purchaser's estimates
     of the Defect Amounts attributable to such Title Defects after giving
     effect, if any, to Shareholders' curative efforts and (y) all other
     unresolved disputes with respect to Title Defects and/or Defect Amounts.
     For a period of thirty (30) days after Shareholders' receipt of such
     written list, Shareholders and Purchaser shall attempt to resolve disputes
     as to such items. With respect to all such disputes which the parties are
     unable to resolve, Shareholders shall at any time on or before the fifth
     (5th) Business Day after the expiration of such 30-day period elect to
     either (i) submit any or all of such disputes to arbitration in accordance
     with Section 9.1(h) or (ii) cause the Property or Properties affected by
     such disputes which are not submitted to arbitration to be conveyed to
     either Shareholder or their designee as set forth in Section 9.1(e) with a
     limited warranty of title with respect to Title Defects created by,
     through or under any of the Companies or Subsidiary on or after the
     Closing Date; provided that Purchaser shall have the right to make a Title
     Waiver at any time prior to such conveyance, in which case the Property or
     Properties shall not be conveyed pursuant to Shareholders' election.
     During the Cure Period with respect to a Title Defect, and thereafter
     until all disputes regarding such Title Defect and the Defect Amount in
     respect thereof have been 


                                      49
<PAGE>   61

     fully resolved by agreement or arbitration, Purchaser and the Companies
     shall afford Shareholders and their representatives and agents access at
     all reasonable times to the Companies' and the Subsidiary's files, records
     and documents relating to title to the one or more Properties that are the
     subject of such disputed Title Defect or Defect Amount. Such access shall
     be subject to confidentiality restrictions reasonably imposed by Purchaser
     or the Companies or the Subsidiary. Purchaser shall cause the Companies
     and Subsidiary to implement (at Shareholders' expense) any curative action
     which is jointly agreed upon by Purchaser and Shareholders.

          (h)  Arbitration.

               (i) Shareholders and Purchaser agree to jointly select an
          arbitrator experienced in U.S. oil and gas title matters, who shall
          be the sole arbitrator (the "Arbitrator") to hear and decide all
          disputes regarding asserted Title Defects and Defect Amounts
          ("Arbitrable Disputes") within thirty (30) days after Shareholders
          elect to submit any Arbitrable Disputes to arbitration. The
          Arbitrator chosen shall be impartial and independent of all parties
          to this Agreement and shall be experienced and knowledgeable about
          the subject matter (generally and not as to the express facts
          concerning Company Property) of the disputes. If the Parties are
          unable to agree upon the designation of a person as Arbitrator, then
          Shareholders or Purchaser may in writing request the Houston, Texas
          office of the AAA to appoint the Arbitrator and such Arbitrator shall
          hear all matters submitted to arbitration under this Section 9.1(h);

               (ii) Each arbitration hearing shall be held at a place in
          Houston, Texas acceptable to the Arbitrator. The arbitration shall be
          conducted in accordance with the Commercial Arbitration Rules of the
          AAA. The decision of the Arbitrator with respect to Arbitrable
          Disputes shall be reduced to writing and binding on the parties.
          Judgment upon the award(s) rendered by the Arbitrator may be entered
          and execution had in any court of competent jurisdiction or
          application may be made to such court for a judicial acceptance of
          the award and an order of enforcement. Notwithstanding any choice of
          law provision in this Agreement, the United States Federal
          Arbitration Act (9 U.S.C. Sections 1-16) shall govern the
          interpretation and enforcement of this arbitration provision.
          Shareholders and Purchaser, respectively, shall bear their own legal
          fees and other costs incurred in presenting their respective cases.
          The charges and expenses of the Arbitrator shall be shared one-half
          by the Shareholders and one-half by Purchaser;

               (iii) The arbitration hearing shall commence within thirty (30)
          days after the Arbitrator is selected in accordance with the
          provisions of Section 9.1(h)(i) above. In fulfilling his or her
          duties with respect to determining the amount of a Defect Amount, the
          Arbitrator may consider such matters as, in the opinion of the
          Arbitrator, are necessary or helpful to make a proper valuation,
          however, the 


                                      50
<PAGE>   62

          Arbitrator shall be bound by those factors set forth in Section 9.1
          above. Furthermore, the Arbitrator may consult with and engage
          disinterested third parties to advise the Arbitrator including,
          without limitation, geologists, geophysicists, petroleum engineers,
          title lawyers, accountants and consultants and the fees and expenses
          of such third parties shall be considered to be charges and expenses
          of the Arbitrator. The sole remedy in any arbitration award shall be
          resolution of alleged Title Defects and Defect Amounts which shall
          then be applied as provided in Section 9.1(i) and the Arbitrator
          shall not have power to award any other remedy, including without
          limitation actual damages, exemplary damages, attorneys' fees and
          interest reflecting the time value of money. The Arbitrator shall not
          add any interest factor reflecting the time value of money to any
          Defect Amount;

               (iv) If the Arbitrator selected hereunder (whether selected by
          Shareholders and Purchaser or by the AAA) should die, resign or be
          unable to perform his or her duties hereunder, the parties or AAA
          shall select a replacement Arbitrator. The procedure set forth in
          this Section 9.1(h)(iv) for selecting a replacement Arbitrator shall
          be followed from time to time as necessary;

               (v) As to any determination of amounts owing under the terms of
          this Section 9.1(h), no lawsuit based on such claimed amounts owing
          shall be instituted by any party hereto, other than to compel
          arbitration proceedings or enforce the award of the Arbitrator; and

               (vi) All privileges under Texas and federal law, including
          attorney-client and work-product privileges, shall be preserved and
          protected to the same extent that such privileges would be protected
          in a federal court proceeding applying Texas law.

          (i) Post-Closing Adjustment for Uncured Title Defects. At mutually
     agreeable times, but in all events when the last of all Title Defects
     asserted by the Purchaser and the Defect Amounts, if any, with respect
     thereto have been finally resolved, whether by agreement, arbitration
     award or conveyance of the Properties affected thereby to either
     Shareholder or their designee, the Purchase Price shall be reduced by the
     aggregate amount of the Defect Amounts for all Title Defects which are
     upheld or established and the aggregate Value of all Properties so
     conveyed. The amount of each reduction in the Purchase Price pursuant to
     this Section 9.1(i) shall bear interest at the Agreed Rate from the
     Closing Date until paid. Any reduction in the Purchase Price, together
     with any interest accruing thereon, shall be due and payable by
     Shareholders to Purchaser in immediately available funds within ten days
     after the date of the final resolution of the last of all Title Defects
     asserted by Purchaser and the Defect Amounts associated therewith.
     Notwithstanding any provision in this Agreement to the contrary, (a)
     Shareholders' sole responsibility and Purchaser's sole and exclusive
     remedy for the 


                                      51
<PAGE>   63

     reduction in value of any of the Companies' or Subsidiary's title to a
     Property resulting from the existence of a Title Defect shall be as
     provided in this Section 9.1 and Shareholders shall not be liable for any
     consequential damages or other Losses in respect of Title Defects and
     Defect Amounts, and (b) the foregoing shall not operate to limit
     Shareholders' responsibility for any reductions to the Purchase Price
     pursuant to Section 9.2, or for any breach of any other provision of this
     Agreement to the extent provided in Article X, except that any recovery to
     which Purchaser may be entitled on account of such matters shall not be
     duplicative of any amount recovered by Purchaser under this Section 9.1.

     9.2  Adjustments for Environmental Matters.

          (a) Availability of Data to Purchaser. After execution of this
     Agreement, Shareholders, the Companies and the Subsidiary shall make
     available to Purchaser (and its representatives) all information which is
     in the possession or control of Shareholders, the Companies or the
     Subsidiary or to which the Shareholders, the Companies or the Subsidiary
     have access (other than publicly available information to which Purchaser
     has equal access) and which relates to Environmental Matters of the
     Companies or the Subsidiary or the environmental condition of any Company
     Property, including, without limitation, information regarding
     environmental audits and investigations; alleged violations of
     Environmental Laws; correspondence and filings with environmental
     agencies; crude oil and produced water that may have been spilled or
     disposed of on-site and the locations thereof; pits and pit closures;
     burial of wastes or other materials regulated under Environmental Laws;
     land farming; land spreading; underground injection; and solid waste
     disposal sites, in each case other than any such records or information
     which Shareholders reasonably believe is subject to a legal privilege
     ("Privileged Information") whereby disclosure would result in the waiver
     thereof, provided that Shareholders shall identify for Purchaser each
     Property with respect to which such Privileged Information exists.
     Shareholders agree that at least one officer of one of the Companies shall
     be deemed to have actual knowledge of all Environmental Matters with
     respect to which information asserted by Shareholders to be Privileged
     Information relates. Also, prior to the Closing, Purchaser shall have the
     right at its own risk and expense to conduct or have conducted a Phase I
     Environmental Audit, copies of which shall be promptly provided to
     Shareholders. To enable Purchaser to conduct the Phase I Environmental
     Audit, Shareholders, the Companies and the Subsidiary will provide
     Purchaser (and its representatives) with reasonable access to Company
     Property, subject to any third party restrictions on the Companies or
     Subsidiary with respect to access to Company Property, and will make
     available for Purchaser employees of Shareholders, the Companies or the
     Subsidiary and contractors or consultants to Shareholders, the Companies
     or the Subsidiary. In conducting the Phase I Environmental Audit,
     Purchaser shall treat, and will cause all of its assigns, representatives,
     agents, consultants, contractors or subcontractors to treat, all
     information obtained by Purchaser pursuant to the Phase I Environmental
     Audit and otherwise pursuant to this Section as strictly confidential
     (except to the extent such information is otherwise available to the


                                      52
<PAGE>   64

     general public) and will not disclose such information without the prior
     written consent of Shareholders, except to the extent that such
     information is legally required to be disclosed by Purchaser, in which
     event Purchaser may disclose such information upon notice given to
     Shareholders. Shareholders shall have the right to be present during any
     inspection of Company Property and during any interviews of the Companies'
     or the Subsidiary's employees, contractors, or consultants conducted as a
     part of the Phase I Environmental Audit. Purchaser shall provide
     Shareholders advance notice of such inspections and interviews. Purchaser
     agrees to release, indemnify, defend, and hold Shareholders, the Companies
     and the Subsidiary harmless from any fines, penalties or damage to persons
     or property caused by the activities of Purchaser or its representatives,
     agents, consultants, contractors or subcontractors in conducting the Phase
     I Environmental Audit and other inspections permitted under this Section
     9.2, except to the extent the damage arises from the negligence or
     misconduct of Shareholders, the Companies or the Subsidiary. Should
     Purchaser desire to conduct any procedures for environmental assessment
     outside the scope of the Phase I Environmental Audit, Purchaser must make
     written request for Shareholders' permission to do so, and will not
     commence such procedures without first obtaining Shareholders' written
     permission, which permission will not be unreasonably denied and will be
     either given or denied not later than three (3) Business Days after
     receipt of Purchaser's written request. If within such three-day period
     Shareholders refuse to permit any request by Purchaser to conduct an
     environmental assessment outside the scope of a Phase I Environmental
     Audit, Purchaser shall have the right to cause the Property affected
     thereby to be acquired by Shareholders (or their designee) in accordance
     with the procedures set forth in Section 9.2(b).

          (b) Identification of Environmental Matters Prior to Closing. If, in
     the course of Purchaser's environmental due diligence in connection with
     this transaction, Purchaser reasonably concludes that Environmental
     Liabilities exist relating to the Companies, the Subsidiary, any Company
     Property, or any business, operations, or activities conducted by the
     Companies or the Subsidiary, then Purchaser shall advise Shareholders in
     writing of each such discovered Environmental Liability as soon as is
     feasible, but in all events on or before three (3) Business Days prior to
     the Closing Date. Each such written notification shall contain a
     reasonable description of the facts relied upon by Purchaser in making its
     determination that such an Environmental Liability exists and shall
     identify the Company Property affected by such Environmental Liability (an
     "Affected Property"). Purchaser shall attempt to estimate in good faith
     the scope of and cost to remedy the identified Environmental Liabilities
     associated with an Affected Property in accordance with then-applicable
     Environmental Law and, upon receipt of appropriate supporting information,
     shall give written notice to Shareholders of its conclusions and its good
     faith estimate of the amount of such Environmental Liabilities. Purchaser
     shall give Shareholders written notice of its good faith estimate of the
     amount of such Environmental Liabilities on and as of the third (3rd)
     Business Day prior to the Closing Date. Upon receipt of Purchaser's notice
     that an Environmental Liability exists, Shareholders shall attempt (or
     cause the Companies or the Subsidiary to attempt) to 


                                      53
<PAGE>   65

     remedy the situation to Purchaser's reasonable satisfaction prior to
     Closing, or if Shareholders dispute that an Environmental Liability exists
     or the magnitude thereof or if remediation is not feasible, then
     Shareholders shall negotiate with Purchaser as to the existence or
     magnitude of such identified Environmental Liability. In the event
     Purchaser and Shareholders are able to mutually agree upon an acceptable
     adjustment to the Purchase Price to account for such identified
     Environmental Liability, then the cash portion of the Purchase Price shall
     be adjusted downward by the agreed amount and Shareholders shall have no
     further responsibility or liability to Purchaser either pursuant to this
     Agreement (including Section 10.6) or at law with respect to the specific
     Environmental Liability referenced in Purchaser's notice to Shareholders.
     If the parties do not agree upon an acceptable Purchase Price adjustment,
     then Shareholders shall either (x) submit the adjustment to the Purchase
     Price to arbitration in accordance with procedures identical to the
     procedures set forth in Section 9.1(h), other than the last three
     sentences of clause (iii) thereof, for which the following three sentences
     shall be substituted, with the Arbitrator to be experienced in
     environmental matters, or (y) cause the Companies or the Subsidiary to
     convey the Affected Property in accordance with this Section 9.2(b). The
     Arbitrator in any such arbitration may consult with and engage
     disinterested third parties to advise the Arbitrator including, without
     limitation, environmental engineers, accountants and consultants and the
     fees and expenses of such third parties shall be considered to be charges
     and expenses of the Arbitrator. The sole remedy in any arbitration award
     shall be resolution of alleged Purchase Price adjustments based on
     Environmental Liabilities and the Arbitrator shall not have power to award
     any other remedy, including without limitation actual damages, exemplary
     damages, attorneys' fees and interest reflecting the time value of money.
     The Arbitrator shall not add any interest factor reflecting the time value
     of money to any Purchase Price adjustment. Each unresolved dispute as to
     the amounts of an adjustment under this Section 9.2(b) shall be submitted
     to arbitration unless Shareholders elect to cause the Companies or the
     Subsidiary to convey the Affected Property, effective as of the Effective
     Date to either the Shareholders or an entity designated by Shareholders,
     in which case the cash portion of the Purchase Price shall be reduced by
     the Value of the Affected Property, adjusted to reflect the revenues and
     expenditures (including capital expenditures) attributable to the Affected
     Property since the Effective Date, provided that (i) Shareholders fully
     indemnify the Companies, the Subsidiary and Purchaser (and the other
     Persons named as indemnitees in Section 10.6(a)) from and against any and
     all Environmental Liabilities attributable to the Affected Property, in
     the manner provided in Section 10.6, except that such indemnity shall not
     be subject to or limited as to any amount, any deductible, any threshold
     amount, any survival period or any other restrictions, if any, set forth
     in this Agreement, and (ii) the conveyance of such Affected Property shall
     be by an instrument of assignment or conveyance which is expressly made
     without any warranty or representation, express or implied, as to title,
     condition or any other matter (but, to the extent transferable, with
     subrogation of Shareholders (or such designee) to all covenants and
     warranties theretofore made by any of the Companies' or Subsidiary's
     predecessors in title, except any subsidiary or Affiliate of the Companies
     or Subsidiary). In the event Shareholders elect to submit an adjustment to
     arbitration, the 


                                      54
<PAGE>   66

     Closing shall not be delayed on account thereof, and the Purchase Price
     shall be adjusted upon the conclusion of each such arbitration proceeding,
     according to the Arbitrator's decision. Any adjustment awarded by the
     Arbitrator shall bear interest at the Agreed Rate from the Closing Date
     until paid. This Section 9.2(b) applies only to Environmental Liabilities
     identified by Purchaser on or before three (3) Business Days prior to the
     Closing Date. The provisions of this Section 9.2(b) shall not apply to the
     claim disclosed as item 17 of Schedule 3.8.

          (c) Election to Terminate. Notwithstanding anything to the contrary
     in this Agreement, if, on or before 5:00 p.m. on the second (2nd) Business
     Day prior to the Closing Date, Purchaser has identified one or more
     Environmental Liabilities that on or prior to the Closing Date have not
     been fully remedied by Shareholders, accepted by Purchaser pursuant to
     Section 9.2(b), or conveyed to Shareholders or their designee pursuant to
     Section 9.2(b), and that are estimated in good faith by either Purchaser
     or Shareholders to be in excess of $25,000,000 in the aggregate, then
     either Purchaser or the Shareholders may elect to terminate this Agreement
     prior to the Closing in accordance with the provisions of Section 8.1(e)
     hereof.

     9.3  Tax Matters.

          (a)  Liabilities for Taxes.

               (i) Shareholders shall be liable for all federal income taxes
          (and state and local income taxes of taxing jurisdictions in which
          Parent files a consolidated, combined or unitary income tax return
          with a Company or Subsidiary) (A) imposed on the Companies or
          Subsidiary pursuant to Treas. Reg. Section 1.1502-6 or similar
          provision of state or local law as a result of the Companies or such
          Subsidiary having been a member of the MEC Group, or (B) imposed on
          the Companies or Subsidiary, or for which the Companies or Subsidiary
          may otherwise be liable, for any Taxable year or period that ends
          before or includes the Closing Date, including any such taxes imposed
          (y) as a result of a Company or Subsidiary being a member of an
          affiliated group, other than the MEC Group or (z) by any taxing
          jurisdiction with respect to which a Section 338(h)(10) Election is
          made, but excluding any transactions occurring on the Closing Date
          (other than the Section 338(h)(10) Election, the conveyance of
          properties to Shareholders or their designees pursuant to Section 9.1
          or Section 9.2 and transactions in the ordinary course of business of
          the Companies and Subsidiary) which are not directly related to the
          sale of the Shares (the "Excluded Transactions"). Purchaser shall
          reimburse Shareholders for any such income taxes attributable to the
          Excluded Transactions. Shareholders shall be entitled to any


                                      57
<PAGE>   69

          refund of (or credit for) Taxes allocable to any Taxable year or
          period that ends on or before the Closing Date (other than the
          portion of such refund which is attributable to the Excluded
          Transactions, which refund shall be for the account of Purchaser).

               (ii) Purchaser shall be liable for all federal, state and local
          income taxes imposed on the Companies or Subsidiary or for which the
          Companies or Subsidiary may otherwise be liable for any Taxable year
          or period that begins after the Closing Date.

               (iii) Notwithstanding subsection (i) of this Section 9.3(a), if
          a Company or Subsidiary, as the case may be, consistent with prior
          years' practice, is included in any consolidated, combined or unitary
          income tax return filed by Parent, but the Taxable year of such
          Company or Subsidiary does not terminate as a result of the Section
          338(h)(10) Election (or its equivalent under state or local income
          Tax law) the Shareholders shall be liable for the income taxes
          imposed by that jurisdiction for the Straddle Year, provided,
          however, that Purchaser shall reimburse Shareholders for such income
          taxes which are attributable to the Excluded Transactions plus such
          income taxes attributable to the activities of the Companies and
          Subsidiary from the day following the Closing Date through the last
          day of the Straddle Year (or if the result of such activities
          aggregated with the income taxes resulting from the Excluded
          Transactions results in a tax savings to Shareholders, Shareholders
          shall pay such tax savings to Purchaser). (The "Straddle Year" shall
          mean any Taxable year that begins before and ends after the Closing
          Date.) The portion of such income taxes attributable to the period
          from the day following the Closing Date shall be determined on a
          "closing of the books as of the close of business on the Closing
          Date" basis, except that exemptions, allowances and deductions that
          are determined on an annual basis shall be allocated on a daily
          basis.

               (iv) Except as otherwise provided in this Section 9.3(a), if a
          Company or Subsidiary, as the case may be, consistent with prior
          years' practice, is not included in any consolidated, combined or
          unitary state or local income tax return filed by Parent, such
          Company or Subsidiary shall be liable for its state income taxes. To
          the extent that a Company's or Subsidiary's liability for such taxes
          for Taxable years ending on or before June 30, 1996 plus the portion
          of such taxes for the portion of the Straddle Year ending on June 30,
          1996 is more than the reserve for such taxes included in the Most
          Recent Financial Statements, Shareholders shall pay to Purchaser such
          excess (together with the applicable amount of any interest and
          penalties payable to the applicable taxing jurisdiction with respect
          to such excess). The portion of such taxes which is attributable to
          the portion of the Straddle Year ending on June 30, 1996 shall be
          determined on a "closing of the books as of the close of business on
          June 30, 1996" basis,


                                      58
<PAGE>   70

          except that exemptions, allowances and deductions that are determined
          on an annual basis shall be allocated on a daily basis.

               (v) Except as otherwise provided in Section 9.3(a)(vi), the
          Companies or Subsidiary, as the case may be, will be liable for all
          other Taxes. To the extent that a Company's or Subsidiary's liability
          for such Taxes for Taxable years ending on or before June 30, 1996
          plus the portion of the Straddle Year ending on June 30, 1996 is more
          than the reserve for such Taxes included in the Most Recent Financial
          Statements, Shareholders shall pay to Purchaser such excess (together
          with the applicable amount of any interest and penalties payable to
          the applicable taxing jurisdiction with respect to such excess). The
          portion of such Taxes which is attributable to the portion of the
          Straddle Year ending on June 30, 1996 shall be determined on a
          "closing of the books as of the close of business on June 30, 1996"
          basis, except that exemptions, allowances and deductions that are
          determined on an annual basis shall be allocated on a daily basis.

               (vi) Notwithstanding anything herein to the contrary, Purchaser
          shall pay fifty percent (50%) and Shareholders shall pay fifty
          percent (50%) of any real property transfer or gains Tax, sales Tax,
          use Tax, stamp Tax, stock transfer Tax, or other similar Tax imposed
          on the transactions contemplated by this Agreement.

          (b)  Responsibility for Tax Returns.

               (i) Shareholders shall file or cause to be filed when due all
          Tax returns that are required to be filed by or with respect to the
          Companies and Subsidiary on or before the Closing Date (taking into
          account all extensions permitted by applicable law) and Shareholders
          shall remit or cause to be remitted to the appropriate taxing
          authority any Taxes due in respect of such Tax returns, and Purchaser
          shall file or cause to be filed when due all Tax returns that are
          required to be filed by or with respect to the Companies and
          Subsidiary after the Closing Date (taking into account all extension
          permitted by applicable law) and Purchaser shall remit or cause to be
          remitted to the appropriate taxing authority any Taxes due in respect
          of such Tax returns. Notwithstanding the preceding sentence,
          Shareholders shall file or cause to be filed the federal (and, in
          jurisdictions in which consolidated, combined or unitary income Tax
          returns are filed, state and local) income Tax returns for the
          Straddle Year and shall remit or cause to be remitted to the
          appropriate taxing authority any Taxes due in respect of such Tax
          returns. Any Tax return required to be filed by Shareholders or
          Purchaser pursuant to this Section 9.3(b) relating in whole or in
          part to Taxes for which the other party(ies) may be liable pursuant
          to the provisions of Section 9.3(a) or its representations set forth
          in Section 3.7 shall be submitted to the other party for the other
          party's approval not later than 30 days prior to the due date for the
          filing of such Tax return (taking into account all extensions
          permitted by


                                      59
<PAGE>   71

          applicable law); except that the material to be submitted by
          Shareholders or Purchaser may be limited to the results of operations
          of the Companies and Subsidiary. All Tax returns which Shareholders
          or Purchaser are required to file or cause to be filed in accordance
          with this Section 9.3(b) shall, to the extent permitted by applicable
          law, be prepared and filed in a manner reasonably consistent with
          past practice.

               (ii) None of Purchaser or any Affiliate of Purchaser shall (or
          shall cause or permit the Companies or Subsidiary to) amend, refile
          or otherwise modify any Tax return relating in whole or in part to
          the Companies or Subsidiary with respect to any Taxable year or
          period ending on or before the Closing Date without the prior written
          consent of Shareholders, which consent may be withheld in the sole
          discretion of Shareholders. None of Shareholders, the MEC Group or
          any of their Affiliates shall or shall cause or permit any amendment,
          refiling or modification of any Tax return relating in whole or in
          part to the Companies or Subsidiary with respect to any Taxable year
          or period ending on or before the Closing Date, if such amendment,
          refiling or modification could be reasonably expected to have any
          adverse effect on Purchaser, Companies or Subsidiary without the
          prior written consent of Purchaser, which consent may be withheld in
          the sole discretion of Purchaser.

               (iii) Purchaser shall promptly cause the Companies and
          Subsidiary to prepare and provide to Shareholders a package of Tax
          information materials, including, without limitation, schedules and
          work papers (the "Tax Package") required by Shareholders to enable
          Shareholders to prepare and file all Tax returns required to be
          prepared and filed by Shareholders pursuant to this Section 9.3(b).
          The Tax Package shall be completed in accordance with past practice,
          including past practice as to providing such information and as to
          the method of computation of separate Taxable income or other
          relevant measure of income of the Companies and Subsidiary. Purchaser
          shall cause the Tax Package to be delivered to Shareholders not later
          than 30 days prior to the due date for such return (taking into
          account all extensions permitted by applicable law).

          (c) Contest Provisions. Purchaser shall promptly notify Shareholders
     in writing upon receipt by Purchaser, any of its Affiliates, the Companies
     or any Subsidiary of notice of any pending or threatened federal, state or
     local Tax audits, examinations or assessments which could reasonably be
     expected to affect the Tax liabilities for which Shareholders may be
     responsible pursuant to Section 9.3(a). Shareholders shall promptly notify
     Purchaser in writing upon receipt by Shareholders or any of their
     Affiliates of notice of any pending or threatened federal, state or local
     Tax audits, examinations or assessments which could reasonably be expected
     to affect the Tax liabilities for which Purchaser may be responsible
     pursuant to Section 9.3(a). Shareholders, at their sole cost, shall have
     the sole right to represent the Companies' and Subsidiary's interests in
     any Tax audit or administrative or court proceeding (a "Tax Proceeding")
     relating to


                                      60
<PAGE>   72

     Taxable periods ending on or before the Closing Date and to employ counsel
     of its choice at its expense. Purchaser, at its sole expense, shall have
     the sole right to represent the Companies' and Subsidiary's interests in
     any Tax Proceeding relating to Taxable periods ending after the Closing
     Date and to employ counsel of its choice at its expense. Notwithstanding
     the third and fourth sentences of this Section 9.3(c), in the case of a
     Tax Proceeding for the Taxable year in which the Closing Date occurs for
     which the Shareholders may be liable pursuant to Section 9.3(a) or
     required to indemnify Purchaser pursuant to its representations set forth
     in Section 3.7, Shareholders shall be entitled to participate at their
     expense in the portion of such Tax Proceeding relating (in whole or in
     part) to Taxes attributable to the portion of such year for which they
     bear responsibility pursuant to Sections 3.7 or 9.3(a) and, with the
     written consent of Purchaser (which may be withheld in the sole discretion
     of Purchaser) the Shareholders, at their sole expense, may assume the
     entire control of such Tax Proceeding. No deficiency or refund
     attributable to any audit or administrative or judicial proceeding shall
     affect the determination of the Intercompany Payables. None of Purchaser,
     any of its Affiliates, the Companies or Subsidiary may settle any Tax
     claim for any Taxable year or period ending on or before the Closing Date
     (or for the Taxable year in which the Closing Date occurs) which may be
     the subject of indemnification by MCC under Sections 3.7 or 9.3(a) without
     the prior written consent of Shareholders, which consent may be withheld
     in the sole discretion of Shareholders.

          (d) Assistance and Cooperation. After the Closing Date, Shareholders
     and Purchaser shall (and cause their respective Affiliates to):

               (i) assist the other party in preparing any Tax returns which
          such other party is responsible for preparing and filing in
          accordance with Section 9.3(b);

               (ii) cooperate fully in preparing for any audits of, or disputes
          with taxing authorities regarding, any Tax returns of the Companies
          and Subsidiary;

               (iii) make available to the other and to any taxing authority as
          reasonably requested all information, records, and documents relating
          to Taxes of the Companies and Subsidiary;

               (iv) provide timely notice to the other in writing of any
          pending or threatened Tax audits or assessments of the Companies and
          Subsidiary for Taxable periods for which the other may be responsible
          under Section 9.3(b);

               (v) furnish the other with copies of all correspondence received
          from any taxing authority in connection with any Tax audit or
          information request with respect to any such Taxable period; and

               (vi) timely sign and deliver such certificates or forms as may
          be necessary or appropriate to establish an exemption from (or
          otherwise reduce),


                                      61
<PAGE>   73

          or file Tax returns or other reports with respect to, Taxes described
          in paragraph (v) of Section 9.3(a) (relating to sales, transfer and
          similar Taxes).

          (e) Adjustment to Purchase Price. Any payment by Purchaser or
     Shareholders under this Section 9.3 will be an adjustment to the Purchase
     Price.

          (f) Definition of Taxes. For purposes of this Agreement, the term
     "Tax" (and, with correlative meaning, "Taxes" and "Taxable") shall mean
     any federal, state, local or foreign income, gross receipts, property,
     sales, use, license, excise, franchise, severance, employment, payroll,
     withholding, alternative or add-on minimum, ad valorem, value added,
     transfer or excise tax, or any other tax, custom, duty, governmental fee
     or other like assessment or charge of any kind whatsoever, together with
     any interest or penalty, imposed by any taxing authority.

          (g) The Shareholders and the Purchaser shall timely make a joint
     election pursuant to Section 338(h)(10) of the Code and Treas. Reg.
     Section 1.338(h)(10)-1T(d)(1) (the "Section 338(h)(10) Election") for
     federal, state and local income tax purposes (where permissible) with
     respect to the purchase of the Shares as described herein. The Section
     338(h)(10) Election will include the execution on the Closing Date and
     subsequent filing of Internal Revenue Service Form 8023-A pursuant to the
     requirements as stated therein. The Purchaser shall, within the later of
     (i) 45 days after the Closing Date, and (ii) 15 days after the Final
     Closing Date Statement has been accepted, deemed to have been accepted by
     Purchaser or determined in accordance with Section 1.6(e), provide to
     Shareholders an allocation of the deemed purchase price among the assets
     of the Companies and Subsidiary in compliance with Temp. Treas. Reg.
     Section 1.338(b)-2T(b). Such allocation shall be consistent with the
     allocations of the Purchase Price set forth in the Schedules hereto. Such
     allocation shall be deemed acceptable to Shareholders unless they notify
     Purchaser of any objections within 30 days after receipt of such
     allocation. If the Shareholders and Purchaser are unable to agree on such
     allocation within the later of (i) 120 days after the Closing Date and
     (ii) 15 days after the Final Closing Date Statement has been accepted,
     deemed to have been accepted by Purchaser or determined in accordance with
     Section 1.6(e), then an accounting firm chosen in accordance with the
     procedures set forth in Section 1.6(e) shall make a binding determination
     with respect to such allocation in accordance with Section 1.6(e). The
     parties agree that for all Tax purposes, they and their Affiliates will
     report consistently with such allocation of the deemed purchase price.

     9.4 Change of Name. The Purchaser agrees that promptly after consummation
of the transactions contemplated by this Agreement on the Closing Date,
Purchaser will cause a Certificate of Amendment to the certificate of
incorporation of each of IOG and IGS(OK) to be filed with the Secretary of
State of their respective states of incorporation (and such other governmental
offices as are necessary), to effect a change in the names thereof to names not
including the word "InterCoast." The Purchaser shall cause to be removed the
names and marks used by the Companies and Subsidiary containing the words
"InterCoast" and all variations and 


                                      62
<PAGE>   74

derivatives thereof and logos relating thereto from the assets of the Companies
and Subsidiary and will not thereafter make any use nor permit any of the
Companies or Subsidiary to make any use whatsoever of such names, marks and
logos.

     9.5 Retention of Records. For the entire period required by the Internal
Revenue Service, the Department of Labor, or other authorities or agencies for
which any of the Companies or Subsidiary is required to retain records, and for
at least a period of five years after the Closing Date Purchaser shall make
reasonable commercial efforts to ensure the maintenance of all books and
records of the Companies and Subsidiary relating to any period before the
Closing Date, and shall not dispose of or destroy or cause or permit the
disposition or destruction of such books and records before notifying the
Shareholders of the pending destruction or other disposition of such records
and to accord the Shareholders the right for a period of 60 days after such
notice is given to take physical possession of such records. As to such books
and records maintained by Purchaser, the Shareholders and their
representatives, upon at least ten days' notice to Purchaser, shall have
reasonable access during normal business hours to all books and records covered
by this Section 9.5 and relating to any period before the Closing Date, in all
cases for tax or other regulatory purposes, financial reporting purposes,
litigation or dispute resolution purposes and other valid business purposes.
Purchaser's compliance with this Section 9.5 shall be without cost to the
Shareholders except that the Shareholders shall pay or reimburse Purchaser for
Purchaser's out-of-pocket third party costs and expenses incurred in complying
with this Section

     9.6 Fees and Expenses. Except as otherwise explicitly provided in this
Section 9.6, all fees, costs and expenses incurred by the Purchaser and the
Shareholders in negotiating this Agreement and in consummating the transactions
contemplated by this Agreement shall be paid by the party incurring the same,
including, without limitation, legal, engineering and accounting fees, costs
and expenses. Without limiting the foregoing, the Shareholders (and not any of
the Companies or Subsidiary, directly or indirectly) shall pay all of such
fees, costs and expenses incurred or caused to be incurred by them on or prior
to the Closing Date, including, without limitation, those in connection with
their curing of Title Defects pursuant to Section 9.1 and the remedying of
Environmental Liabilities pursuant to Section 9.2 in accordance with the
provisions of those Sections; provided, however, that (i) the costs and
expenses of the Companies and the Subsidiary in connection with the preparation
of the summaries referred to in Section 9.1(a) shall be paid by the Companies
and Subsidiary and (ii) the fees and expenses of Arthur Andersen LLP in
connection with the preparation of the Financial Statements shall be paid by
Purchaser. References herein to costs or expenses to be paid by the
Shareholders means that such costs or expenses shall be paid solely by the
Shareholders (and not by any of the Companies or Subsidiary, directly or
indirectly).

     9.7  Employee Benefits Plan and Practices.

          (a)  Employee Benefits Generally.

               (i) Except as otherwise specifically provided in this Section
          9.7, effective as of the Closing, Shareholders shall cause each of
          the Companies and Subsidiary to cease to be participating employers
          under any Plans which are sponsored or maintained by Shareholders,
          Parent or any of their Affiliates other than the Companies or
          Subsidiary ("Upstream Affiliates"), such Plans being herein referred
          to as "Parent's Benefit Plans." Effective on and after the Closing,
          except as otherwise specifically provided in this Section 9.7,
          Purchaser will provide, or ensure that the Companies and Subsidiary
          provide, individuals who are employed by any of the Companies or
          Subsidiary on the Closing Date and who continue in the employment of
          any of the Companies, Subsidiary or the Purchaser after the Closing
          (including those on vacation) (hereinafter "Continuing Employees")
          with benefits under benefit plans sponsored by Purchaser and in
          effect from time to time ("Purchaser's Benefit Plans"), subject to
          this Section 9.7; provided, however, that none of the individuals
          described in Section 9.7(h)(i) shall be deemed to be a Continuing
          Employee for any purposes of this Agreement unless and until he or
          she shall have resumed full-time employment with the Companies or the
          Subsidiary for a period of thirty (30) consecutive Business Days
          after the Closing Date. In that connection, Purchaser shall amend
          Purchaser's Benefit Plans to the extent necessary or appropriate to
          credit Continuing Employees under Purchaser's Benefit Plans for their
          period of employment with any of the Companies or Subsidiary or any
          of their Affiliates.

               (ii) On and after the Closing Date, Purchaser agrees that the
          Companies or Subsidiary shall be responsible and liable for (and
          Purchaser shall cause the Companies or Subsidiary to pay) any
          payment, obligation or benefit under all Plans and policies sponsored
          or maintained by the Companies or Subsidiary, including without
          limitation, vacation and sick leave earned through the Closing Date
          and worker's compensation (the "Company's Separate Plans") with
          respect to Continuing Employees or former employees of the Companies
          or Subsidiary whether such payment, obligation or benefit was earned
          or incurred prior to or on or after the Closing Date; provided,
          however, (1) that the foregoing shall not apply to (A) the Long-Term
          Incentive Plan or (B) the liabilities and obligations under the
          InterCoast Oil and Gas Company Change in Control and Severance
          Agreements allocated to any Upstream Affiliate under Schedule 9.7(j)
          and (2) that the Shareholders shall promptly reimburse GED (or any
          successor) for one-half (not to exceed $72,000) of the amounts
          payable to participants and beneficiaries under GED's Performance
          Incentive Plan ("PIP") for 1996. Nothing herein shall preclude
          amendment or termination of any of the Company's Separate Plans.

               (iii) On and after the Closing Date, except as provided in
          Section 9.7(a)(ii) with respect to the Company's Separate Plans or as
          otherwise specifically provided in this Section 9.7, neither the
          Purchaser nor any of its Affiliates shall be responsible or liable
          for any payment or benefit under any type of Plan, policy, or
          arrangement, whether written or unwritten, collective or individual,
          formal or informal, of any of the Companies or Subsidiary or any of
          their Benefits Affiliates (defined below) including, without
          limitation, any liabilities arising from the Coal Industry Retiree
          Health Act of 1992. The term "Benefits Affiliate" means (i) any
          corporation that is a member of a controlled group of corporations
          (as defined in section 414(b) of the Code) that includes the
          Companies, (ii) any trade or business (whether or not incorporated)
          that is under common control (as defined in section 414(c) of the
          Code) with the Companies, (iii) any organization (whether or not
          incorporated) that is a member of an affiliated service group (as
          defined in section 414(m) of the Code) that includes the Companies,
          and (iv) any other entity required to be aggregated with the
          Companies pursuant to regulations issued under section 414(o) of the
          Code. On and after the Closing Date, except as specifically provided
          in this Section 9.7, Shareholders shall be, or shall cause any
          Upstream Affiliate that sponsors any Plan, policy or arrangement
          described in the first sentence of this Section 9.7(a)(iii) to be,
          liable for all such liabilities described in the first sentence of
          this Section 9.7(a)(iii).

          (b) Upstream Affiliate's Tax Qualified Plans. Shareholders shall
     prevent any Upstream Affiliate from causing the transfer to any of
     Purchaser's Benefit Plans any assets or liabilities of any tax-qualified
     defined benefit pension plan or tax-qualified defined contribution plan of
     the Upstream Affiliate (the "Upstream Affiliate's Qualified Pension
     Benefit Plans"). Effective as of the date immediately prior to the Closing
     Date, all individuals who as of such date were employed by any of the
     Companies or the Subsidiary and were accruing benefits or earning service
     credit for vesting under any Upstream Affiliate's Qualified Pension
     Benefit Plans shall become one hundred percent (100%) vested in their
     accrued benefits under such plans as of such date and shall cease to
     accrue any benefits under such Plans. On and after the Closing Date,
     Shareholders shall cause each affected Upstream Affiliate to remain liable
     for the obligations of the Upstream Affiliate's Qualified Pension Benefit
     Plans to the extent required under the terms of the Upstream Affiliate's
     Qualified Pension Benefit Plans or applicable laws.

          (c) Participation of Continuing Employees in Purchaser's Tax
     Qualified Plan. Notwithstanding any other provision of this Section 9.7,
     the Purchaser shall use its best efforts to cause the Companies and
     Subsidiary to adopt Purchaser's tax-qualified defined contribution plan as
     in effect from time to time (the "Purchaser's Qualified Pension Benefit
     Plan") as of the Closing Date, but in any event Purchaser shall cause such
     adoption within 45 days following the Closing Date. Purchaser shall use
     its best efforts to allow the Continuing Employees in eligible categories
     who satisfy applicable age and service requirements to be eligible to
     participate in the Purchaser's Qualified Pension


                                      65
<PAGE>   77

     Benefit Plan as of the Closing Date, but in any event Purchaser shall
     cause such eligibility within 45 days following the Closing Date. A
     Continuing Employee's service with any of the Shareholders, the Companies
     or Subsidiary or any of their Affiliates on and before the Closing Date
     shall be credited under the Purchaser's Qualified Pension Benefit Plan for
     purposes of participation and vesting (but not for benefit accrual).
     Shareholders shall cause Purchaser to be provided any information the
     Purchaser needs to administer this provision. The Purchaser shall cause
     the Purchaser's Qualified Pension Benefit Plan to be amended, if
     necessary, to accept direct rollovers from any Upstream Affiliate's
     Qualified Pension Benefit Plans.

          (d) Incentive and Supplemental Deferred Compensation Plans. Except as
     provided in Section 9.7(a)(ii) with respect to the Company's Separate
     Plans, none of the Purchaser, the Companies or Subsidiary or any of their
     Affiliates shall assume any liabilities with respect to any (i) incentive
     compensation plans (including but not limited to stock options or grants
     of restricted stock) or (ii) nonqualified deferred compensation plan or
     arrangement (including but not limited to any supplemental defined benefit
     plans or any supplemental defined contribution plans), in which Continuing
     Employees or individuals who terminated or retired from any of the
     Shareholders, the Companies or Subsidiary on or prior to the Closing Date
     participate. On and after the Closing Date, Shareholders shall, and shall
     cause the Parent or MidAmerican Capital Company ("MCC") or any other
     Upstream Affiliate to, retain all such liabilities.

          (e)  Welfare Benefit Plans.

               (i) Except as provided in Section 9.7(a)(ii) with respect to the
          Company's Separate Plans, none of the Purchaser, the Companies or
          Subsidiary or any of their Affiliates shall be liable for payment of
          any life insurance, accidental death and dismemberment, disability
          and other welfare benefit plan expenses and benefits for each
          individual employed by any of the Companies or Subsidiary prior to
          the Closing Date ("Company or Subsidiary Employee") with respect to
          claims incurred by such Company or Subsidiary Employee or such
          Company or Subsidiary Employee's covered dependents prior to the
          Closing Date. On and after the Closing Date, Shareholders shall, and
          shall cause the Parent to, retain all liabilities described in the
          immediately preceding sentence. Hospital, medical, life insurance,
          accidental death and dismemberment, disability and other welfare
          benefit plan expenses and benefits with respect to claims incurred by
          any Continuing Employee or such Continuing Employee's covered
          dependents on and after the Closing Date shall be Purchaser's
          responsibility, and Purchaser shall cause such to be the Companies'
          and Subsidiary's responsibility, in accordance with the terms of any
          applicable welfare benefit plan maintained and in effect from time to
          time by Purchaser, the Companies or Subsidiary for the Continuing
          Employee. For purposes of this paragraph, a claim shall be deemed
          incurred when the services giving rise to the claim were performed.



                                      66
<PAGE>   78

               (ii) On and after the Closing Date, the Continuing Employees and
          their eligible dependents shall be eligible to continue as, or to
          become, participants in the group medical, dental, cafeteria and/or
          dependent care Plans that as of the Closing Date are offered by the
          Companies or Subsidiary and subsequently may be in effect from time
          to time. Nothing herein shall preclude amendment or termination of
          any such Plan at any time without notice to Continuing Employees and
          their eligible dependents.

          (f) Continuation Coverage. The Companies or Subsidiary shall be
     liable for the payment of any health expenses incurred for continuation
     coverage under section 4980B of the Code or Part 6 of Title I of ERISA
     with respect to "qualifying events" (within the meaning of section
     4980B(f)(3) of the Code or section 603 of ERISA) occurring on or before
     the Closing Date with respect to Continuing Employees or employees who
     terminated employment with any of the Companies or Subsidiary on or before
     the Closing Date. On and after the Closing Date, the Companies or
     Subsidiary shall cause any "qualified beneficiary" (within the meaning of
     section 4980B(g)(1) of the Code or section 607 of ERISA) with respect to
     such qualifying events to be covered under the Companies' or Subsidiary's
     group health plans that may be in effect for the period of continuation
     coverage. On and after the Closing Date, the Companies and Subsidiary
     shall be responsible and liable, for payments of any health care expenses
     for continuation coverage (i) that are incurred by Continuing Employees
     who terminate employment with or retire from the Purchaser, the Companies
     or Subsidiary after the Closing Date and (ii) that are covered and payable
     under any group health plan of the Purchaser, the Companies or Subsidiary
     in which Continuing Employees participate.

          (g) Life Insurance. None of Purchaser, the Companies or Subsidiary or
     any of their Affiliates shall be liable for claims incurred with respect
     to employees of the Companies and Subsidiary prior to the Closing Date
     under any life insurance plan in which Continuing Employees or individuals
     who were terminated or retired from any of the Shareholders, the Companies
     or Subsidiary participate. Shareholders shall, and shall cause the Parent
     or MCC to, retain liability for all such claims. Subject to Section
     9.7(a)(i), Purchaser shall cause the Companies and Subsidiary to adopt,
     effective as of the Closing Date, Purchaser's Benefit Plans that provide
     death benefit protection. Continuing Employees shall be eligible to
     participate in such plans in accordance with their terms.

          (h)  Disability Benefits.

               (i) Pre-Closing Long-Term Disability. None of Purchaser, the
          Companies or Subsidiary or any of their Affiliates shall be liable
          for the payment of long-term disability benefits to any individuals
          who may or may not have terminated employment with any of the
          Shareholders, the Companies or Subsidiary prior to the Closing Date,
          to the extent that such individuals are (1) receiving long-term
          disability benefits on the Closing Date, or (2) on sick leave


                                      67
<PAGE>   79

          or leave of absence on the Closing Date and (if the sale had not
          occurred) would have become eligible for long-term disability
          benefits immediately following the expiration of such sick leave or
          leave of absence. On and after the Closing Date, Shareholders shall,
          and shall cause Parent or MCC to, retain liability for all such
          payments.

               (ii) Post-Closing Long-Term and Short-Term Disability. On and
          after the Closing Date, Purchaser shall be responsible and liable, or
          shall cause the Companies and Subsidiary to be responsible and
          liable, for payment of any long-term or short-term disability
          benefits (1) that are due to Continuing Employees who terminate
          employment with or retire for disability from Purchaser, the
          Companies or Subsidiary on or after the Closing Date and (2) that are
          covered and payable under any long-term or short-term disability plan
          of the Purchaser, the Companies or Subsidiary, as may be in effect
          from time to time, in which Continuing Employees participate. Subject
          to Section 9.7(a)(i), Purchaser shall cause the Companies and
          Subsidiary to adopt, effective as of the Closing Date, Purchaser's
          Benefit Plans that provide disability benefits. Continuing Employees
          shall be eligible to participate in such plans in accordance with
          their terms.

          (i) Worker's Compensation. On and after the Closing Date, Purchaser
     shall be responsible and liable, or shall cause the Companies and
     Subsidiary to be responsible and liable, for the payment of any portion of
     the unpaid cost and expense of all worker's compensation and the entire
     cost and expense of all employee injury claims arising out of work related
     injuries or illnesses sustained by Company or Subsidiary Employees on or
     before the Closing Date and by Continuing Employees after the Closing
     Date.

          (j) Severance Pay. On and after the Closing Date, Purchaser shall be
     responsible and liable, or shall cause the Companies and Subsidiary to be
     responsible and liable, for payment of any severance benefits in
     accordance with the terms of the severance plan described in Schedule
     9.7(j) as provided therein.

          (k) Certain Employees. Except as otherwise provided in this Section
     9.7, on and after the Closing Date, none of Purchaser, the Companies or
     Subsidiary or any of their Affiliates shall have any obligation to provide
     benefits of any kind to, or with respect to, any individual who, as of the
     Closing Date, is (i) a former employee of any of the Shareholders, the
     Companies or Subsidiary or (ii) an employee or former employee of a
     Benefits Affiliate. On and after the Closing Date, Shareholders shall, and
     shall cause the Parent or MCC to, retain liability for all such
     obligations.

          (l) Purchaser's Plans. Nothing herein shall preclude amendment or
     termination of any of the Purchaser's Benefit Plans (including, without
     limitation, Purchaser's Qualified Pension Benefit Plan), the Company's
     Separate Plans, or any other Plan, program, policy, fund or arrangement of
     the Purchaser, any of the Companies or 


                                      68
<PAGE>   80

     Subsidiary at any time without notice to Continuing Employees or any other
     affected individuals.

          (m) Cooperation. Purchaser and Shareholders agree to cooperate in
     collecting and providing such information as may be required by either in
     order to discharge their respective obligations under this Section 9.7.
     Purchaser and Shareholders each agree to promptly make all payments and
     perform all obligations with respect to which they have retained liability
     under this Section 9.7.

     9.8 Guarantees, Letters of Credit and Similar Instruments. At the Closing
Date, Shareholders and their Affiliates shall use their best efforts to cancel
or assign, and Purchaser shall use its best efforts to replace or assume or
cause its Affiliates to replace or assume, all of the then existing agreements
or obligations as set forth on Schedule 9.8 of the Shareholders and/or their
Affiliates to guarantee or otherwise warrant or ensure the performance of the
Companies and/or Subsidiary. Where any specific customer, supplier or other
beneficiary of a guarantee, letter of credit or similar instrument refuses to
surrender or relinquish any rights under any of Shareholders' guarantees or
obligations, or the guarantees or obligations of an Affiliate of a Shareholder,
Purchaser shall indemnify and hold the Shareholders and such Affiliates
harmless from and against Shareholders' obligations or the obligations of such
Affiliate under such guaranty or obligations until such time that Shareholders'
or Affiliate's obligation terminates by agreement or otherwise. Each of the
Parties shall use reasonable diligence to accomplish such transfers or
assumptions and Purchaser shall use its best efforts to take, or cause to be
taken, such action as is required to obtain any necessary consent or approval
of third parties for such transfers, assumptions or terminations of such
guarantees and obligations of Shareholders or their Affiliates.

          (a) Discontinue Activities. Purchaser agrees to discontinue
     activities under agreements and accounts guaranteed or otherwise supported
     by Shareholders and Affiliates within 90 days following Closing unless
     Shareholders' and Affiliates' guarantees and obligations have been
     released or otherwise terminated.

          (b) Hedging Accounts. At Closing, Shareholders shall transfer their
     open futures, hedges, swaps, collars, puts, calls, floors, caps, options
     or other contracts which are intended to benefit from or reduce or
     eliminate the risk of fluctuations in the price of commodities (including
     Hydrocarbons) or securities (and the corresponding deposits, if any)
     relating to the Companies and Subsidiary reflected in Schedule 3.26 to an
     account designated by Purchaser, and Purchaser shall assume responsibility
     for changes in margin funding as required to maintain the account.

     9.9 Confidential Nature of Information. Each party agrees that it will
treat in confidence all documents, materials and other information which it
shall have obtained regarding the other party during the course of the
negotiations leading to the consummation of the transactions contemplated
hereby (whether obtained before or after the date of this Agreement), the
investigation provided for herein and the preparation of this Agreement and
other related 


                                      69
<PAGE>   81

documents, and, in the event the transactions contemplated hereby shall not be
consummated, each party will return to the other party all copies of nonpublic
documents and materials which have been furnished in connection therewith. Such
documents, materials and information shall not be communicated to any Person
(other than, in the case of Purchaser, to its counsel, accountants, financial
advisors or lenders, and in the case of Shareholders, to their counsel,
accountants, financial advisors or lenders). No Person shall use any
confidential information in any manner whatsoever except solely for the purpose
of evaluating the transactions contemplated by this Agreement or the
negotiation or enforcement of this Agreement or any agreement contemplated
hereby; provided that after the Closing Purchaser, the Companies and Subsidiary
may use or disclose any confidential information related to the Companies,
Subsidiary or their assets or businesses. The obligation of each party to treat
such documents, materials and other information in confidence shall not apply
to any information which (i) is or becomes lawfully available to such party
from a source other than the furnishing party, (ii) is or becomes available to
the public other than as a result of disclosure by such party or its agents,
(iii) is required to be disclosed under applicable law or judicial process, but
only to the extent it must be disclosed, or (iv) such party reasonably deems
necessary to disclose to obtain any of the consents or approvals contemplated
hereby.

     9.10 No Public Announcement. Except as Purchaser and Shareholders may
otherwise consent to in writing, neither Purchaser nor Shareholders shall (nor
shall Shareholders permit the Companies or Subsidiary to), without the approval
of the other, make any press release or other public announcement concerning
the transactions contemplated by this Agreement, except as and to the extent
that any such party shall be so obligated by law or the rules of any stock
exchange or quotation system, in which case the other party shall be advised
and the parties shall use their best efforts to cause a mutually agreeable
release or announcement to be issued; provided that the foregoing shall not
preclude communications or disclosures necessary to implement the provisions of
this Agreement or to comply with the accounting and Securities and Exchange
Commission disclosure obligations.

                                INDEMNIFICATIONS

     10.1 Survival.

          (a) Notwithstanding any investigation at any time made by or on
     behalf of any party hereto, all representations and warranties of the
     parties contained in this Agreement or in any certificate delivered
     pursuant hereto shall survive the Closing Date and shall continue until
     the second anniversary of the Closing Date except as hereinafter provided
     in this Section 10.1. Purchaser's representations and warranties contained
     in Article II with respect to (i) the Warrants shall survive until one
     year after the expiration of the Warrants, and (ii) the Purchaser Shares
     shall survive without time limitation. Shareholders' representations and
     warranties contained in Section 3.13 which give rise to Environmental
     Claims (i) regarding any Onsite Environmental Liability shall survive


                                      70
<PAGE>   82

     until the expiration of Shareholders' indemnification obligations under
     Section 10.6(c)(i) and (ii) regarding any Offsite Environmental Liability
     shall survive until the expiration of Shareholders' indemnification
     obligations under Section 10.6(c)(ii). Shareholders' representations and
     warranties contained in Article III with respect to the Shares shall
     survive without time limitation. Purchaser's exclusive remedies with
     respect to the breach of the representations and warranties set forth in
     Sections 3.6(a) and 3.6(e) are set forth in Section 9.1 and shall be as
     provided in Section 9.1. Purchaser's and Shareholders' rights in respect
     of representations and warranties which survive after the Closing Date
     shall be preserved until a claim with respect thereto is settled or
     satisfied or the applicable statute of limitations period expires,
     provided that notice of such claim, specifying the factual basis of such
     claim in reasonable detail to the extent known by the party giving notice,
     is delivered to the Shareholders or Purchaser, as the case may be, on or
     before the expiration of such survival.

          (b)  Notwithstanding anything to the contrary above or below, the
     representations, warranties and indemnifications made herein with respect
     to federal, state or local income and other Tax matters (including
     liabilities for Taxes, penalties and interest) shall survive the Closing
     Date and shall terminate upon, and only to the extent of, the expiration
     of the statute of limitations applicable to the pertinent taxable years of
     the MEC Group or of any of the Companies or Subsidiary, as the case may
     be.

     10.2 General Indemnification by the Shareholders. Upon and after
consummation of the transactions contemplated hereby, the Shareholders shall
indemnify and hold harmless the Purchaser for the full amount of all losses,
claims, costs, expenses, obligations, settlement, payments, awards, judgments,
fines, penalties, damages, deficiencies and liabilities or other charges
(including reasonable attorneys' fees) (collectively, "Losses"), arising from
or constituting (i) a breach of any of Shareholders' representations or
warranties herein or in any certificate delivered pursuant hereto by or on
behalf of the Shareholders (other than Section 3.6(a), Section 3.6(e), the sole
remedies for the breach thereof being set forth in Section 9.1, and other than
Section 3.13(a) and the other clauses of Section 3.13 to the extent they
address Environmental Matters, the sole remedies for the breach thereof being
set forth in Sections 9.2 and 10.6) or (ii) a breach of or failure to perform
any of the covenants or agreements made by the Shareholders or either of them
in this Agreement which survive the Closing Date and are not covered by Section
9.1, 9.2, 9.3 or 10.3. Notwithstanding the foregoing, the Shareholders shall be
liable under this Section 10.2 only if, and then only to the extent that, the
aggregate amount of any Losses pursuant to this Section 10.2 and any
Environmental Claims pursuant to Section 10.6 for which the Purchaser or any
other Person indemnified hereunder after the Closing Date is entitled to
indemnification (determined without regard to any materiality qualification, if
any, contained in any representation, warranty or covenant giving rise to a
claim for indemnity hereunder) (i) exceeds $750,000 in the aggregate and (ii)
shall not exceed 100% of the Purchase Price. Notwithstanding the preceding
sentence, Purchaser shall be entitled to indemnification for any Losses arising
from failure by the Shareholders to make any payments required to be made under
Section 1.6 as adjustments to the Purchase Price without regard to 


                                      71
<PAGE>   83

the $750,000 limitation set forth in clause (i) of such sentence but
nevertheless subject to clause (ii) of such sentence.

     10.3 Special Indemnification by the Shareholders. Subject to consummation
of the transactions contemplated hereby, the Shareholders shall indemnify and
hold harmless the Purchaser, the Companies, the Subsidiary and each of their
respective Affiliates for (i) 90% of all Losses or Environmental Liabilities
arising from or incurred in connection with item 17 on Schedule 3.8, (ii) 60%
of all Losses arising from or incurred in connection with each of items 2, 10
and 12 on Schedule 3.8, (iii) 100% of all Losses arising from or incurred in
connection with item 5 on Schedule 3.10 (and further described in the second
paragraph of Schedule 3.7) and (iv) 60% of all Losses arising from or incurred
in connection with item 4 on Schedule 3.10, in each of the foregoing clauses to
the extent such claims or matters relate to or arise out of acts or omissions
occurring on or prior to the Closing Date. Notwithstanding the foregoing, the
Shareholders' aggregate liability under clause (i) above shall in no event
exceed 50% of the Purchase Price and such liability shall not be taken into
account for purposes of determining the limitation set forth in clause (ii) of
the last sentence of Section 10.2 or the last three sentences of Section
10.6(b). Shareholders' obligations with respect to any Environmental
Liabilities covered by clause (i) above shall be subject to the provisions of
Section 10.6(d) and 10.6(e) except that (i) the Shareholders shall not be
entitled to submit the appropriate amount of any payments to Purchaser to
arbitration as contemplated by clause (x) of the fifth sentence of Section
10.6(d), (ii) Shareholders' indemnification obligation with respect to an
Affected Property conveyed to a Shareholder (or an entity they designate) shall
be subject to the limitations set forth in this Section 10.3 rather than in
Sections 10.6(b) and 10.6(c), and (iii) in the event the Shareholders dispute
the necessity or efficacy of any workplan (or any amendment or supplement
thereto) submitted under Section 10.6(e), they shall not be entitled to submit
such dispute to arbitration but shall have the election provided in clause (y)
of Section 10.6(d).

     10.4 Indemnification by Purchaser. Upon and after consummation of the
transactions contemplated hereby, the Purchaser shall indemnify and hold
harmless the Shareholders for the full amount of all Losses arising from or
constituting (i) a breach of any of Purchaser's representations or warranties
herein or in any certificate delivered pursuant hereto by or on behalf of
Purchaser or (ii) a breach of or failure to perform any of the covenants or
agreements made by Purchaser in this Agreement which survive the Closing Date.
Notwithstanding the foregoing, the liability of Purchaser under this Section
10.4 shall not exceed 100% of the Purchase Price.

     10.5 Cooperation with Respect to Third Party Claims. The Purchaser and the
Shareholders agree to cooperate with each other in the defense of any
third-party claim pursuant to which indemnification is sought under this
Section 10.5. An indemnified party shall promptly give notice to the
indemnifying party of any third-party claim as to which the indemnified party
may be indemnified under this Agreement. If indemnification is sought with
respect to a third-party claim asserted or brought against an indemnified
party, the indemnifying party shall, upon notice to the indemnified party, be
entitled to assume the defense thereof, jointly with any other indemnifying
party similarly notified (to the extent that such other indemnifying party may


                                      72
<PAGE>   84

wish), with counsel reasonably satisfactory to such indemnified party. After
such notice from the indemnifying party to the indemnified party of its
election to so assume the defense of such a third-party claim, the indemnifying
party shall not be liable to such indemnified party for any legal or other
expenses subsequently incurred by the indemnified party in connection with the
defense thereof, other than reasonable and necessary costs of investigation,
unless the indemnifying party has failed to assume such defense and to employ
counsel reasonably satisfactory to such indemnified party. If the indemnifying
party gives such notice of assumption of such defense and then fails to assume
or carry on such defense, the indemnifying party shall indemnify and hold
harmless the indemnified party against any loss, cost or expense suffered as a
result thereof. Notwithstanding any of the foregoing to the contrary, the
indemnified party will be entitled to select its own counsel and assume the
defense of any action brought against it if the indemnifying party fails to
select counsel reasonably satisfactory to the indemnified party, the expenses
of such defense to be paid by the indemnifying party.

     10.6 Shareholders' Environmental Indemnification. Notwithstanding any
provision of this Agreement to the contrary, except for the Shareholders'
obligations with respect to Environmental Matters identified in accordance with
Section 9.2 prior to the Closing Date and except as provided in Section 10.3,
the indemnification set forth in this Section 10.6 shall be the sole and
exclusive obligation of Shareholders regarding Environmental Matters and
Environmental Liabilities of the Companies, the Subsidiary or any Company
Property. Shareholders' obligations with respect to Environmental Matters and
Environmental Liabilities arising from or incurred in connection with item 17
of Schedule 3.8 shall be governed by Section 10.3 rather than this Section 10.6
except to the extent contemplated by Section 10.3.

          (a) Shareholders agree, subject to the general notice provisions set
     forth in Section 10.7 and the limitations of this Section 10.6 as
     hereinafter set forth, to indemnify, defend, and hold harmless the
     Companies, the Subsidiary and Purchaser and the Companies', the
     Subsidiary's and Purchaser's respective Affiliates, from and against any
     and all Environmental Liabilities imposed upon, asserted against, or
     incurred by the Companies, the Subsidiary or the Purchaser or any such
     Affiliates, arising out of or in connection with (i) any breach of any of
     the representations and warranties set forth in Section 3.13(a), or in the
     other clauses of Section 3.13 to the extent relating to Environmental
     Matters; and (ii) any Environmental Liabilities arising from the
     operations of the Companies and the Subsidiary, or the ownership or
     operation of any current or former Company Property, in each case arising
     out of acts or omissions which occurred prior to the Closing Date
     (collectively "Environmental Claims"); provided, however, that in the
     event that acts or omissions of any Person (other than the Shareholders or
     any Person acting for or on behalf of the Shareholders) after the Closing
     Date caused or contributed to a preexisting circumstance or condition,
     then Shareholders' obligation to indemnify, defend and hold Purchaser, the
     Companies, the Subsidiary and Purchaser's respective Affiliates harmless
     as provided herein shall be reduced to the extent of any Environmental
     Liabilities resulting from such post-Closing acts or omissions.



                                      73
<PAGE>   85

          (b) Shareholders shall be liable under this Section 10.6 only if, and
     then only to the extent that, the aggregate amount of any Losses or
     Environmental Claims for which the Purchaser, any Company, the Subsidiary
     or any other Person indemnified hereunder after the Closing Date is
     entitled to indemnification pursuant to Section 10.2 (determined without
     regard to any materiality qualification contained in any representation,
     warranty or covenant giving rise to a claim for indemnity hereunder) and
     this Section 10.6 exceeds $750,000 in the aggregate. Once such Losses and
     Environmental Claims exceed such $750,000 aggregate amount, Shareholders
     shall be responsible for all Environmental Claims subject to this Section
     10.6 up to an aggregate of $10 million. Should Environmental Claims
     subject to this Section 10.6 exceed $10 million, Shareholders shall only
     be responsible for 90% of any additional Environmental Claims until the
     aggregate of all such Environmental Claims reaches $100 million, at which
     point Shareholders shall have no further responsibility for any
     Environmental Liabilities related to Environmental Claims. Notwithstanding
     the foregoing, Shareholders' aggregate liability under Sections 10.2 and
     10.6 shall in no event exceed 100% of the Purchase Price.

          (c) By way of further limitation, Shareholders' indemnification
     obligations shall survive:

               (i) with respect to Environmental Claims resulting from Onsite
          Environmental Liabilities, only to the extent that Purchaser, any of
          the Companies or the Subsidiary, within two years after the Closing
          Date, provides Shareholders notice of (x) the specific facts and
          circumstances resulting in an Onsite Environmental Liability or such
          an Environmental Claim relating to the breach of Section 3.13, or (y)
          a third party claim relating to an Onsite Environmental Liability
          (however, notice of a lawsuit or administrative proceeding filed
          against Purchaser, any of the Companies or the Subsidiary prior to
          the end of such two year period shall always be timely if Purchaser,
          any of the Companies or Subsidiary give Shareholders notice thereof
          within ten Business Days after being served therewith); and

               (ii) with respect to Environmental Claims arising from Offsite
          Environmental Liabilities, only to the extent that Purchaser, any of
          the Companies or the Subsidiary, within six years after the Closing
          Date, provides Shareholders notice of (x) the specific facts and
          circumstances resulting in such Offsite Environmental Liability or
          such an Environmental Claim relating to the breach of Section 3.13,
          or (y) a third party claim relating to an Offsite Environmental
          Liability (however, notice of a lawsuit or administrative proceeding
          filed against Purchaser, any of the Companies or the Subsidiary prior
          to the end of such six year period shall always be timely if
          Purchaser, any of the Companies or the Subsidiary give Shareholders
          notice thereof within ten Business Days after being served
          therewith).



                                      74
<PAGE>   86

          (d) With respect to any Environmental Liability for which
     Shareholders may have indemnification obligations under this Section 10.6,
     Purchaser shall advise Shareholders of each such discovered Environmental
     Liability in accordance with Section 10.7. Each such notification shall
     contain a reasonable description of the facts relied upon by Purchaser in
     making its determination that such an Environmental Liability may exist,
     shall identify the Affected Property and shall set forth Purchaser's good
     faith estimate of the scope of and cost to remedy the identified
     Environmental Liabilities associated with the Affected Property in
     accordance with Environmental Law. Upon receipt of Purchaser's notice that
     an Environmental Liability may exist, if Shareholders dispute that an
     Environmental Liability exists or the magnitude thereof, then Shareholders
     shall negotiate with Purchaser as to the existence of or magnitude of such
     identified Environmental Liability. In the event Purchaser and
     Shareholders are able to mutually agree upon an acceptable payment to
     Purchaser on account of such identified Environmental Liability, then
     Shareholders shall pay the agreed amount to Purchaser and Shareholders
     shall have no further responsibility or liability to Purchaser either
     pursuant to this Agreement or at law with respect to the Environmental
     Liability referenced in Purchaser's notice to Shareholders. If the parties
     do not agree upon an acceptable payment to Purchaser, then Shareholders
     shall either (x) submit the appropriate amount of the payment to Purchaser
     to arbitration in accordance with procedures identical to the procedures
     referred to in Section 9.2(b), (y) in the case of Onsite Environmental
     Liability, demand that the Companies or the Subsidiary convey the Affected
     Property in accordance with this Section 10.6, but only if the
     Environmental Liability with respect to such Affected Property or series
     of similarly situated Affected Properties is reasonably expected to exceed
     $1,000,000, or (z) elect that corrective, remedial or other actions be
     commenced pursuant to the provisions set forth in Section 10.6(e). If the
     Shareholders demand the Companies or the Subsidiary convey the Affected
     Property, then the Company or Subsidiary owning the same shall convey such
     Affected Property to either Shareholder or an entity designated by
     Shareholders, and the purchase price for such Affected Property shall be
     the fair market value of such Affected Property at the time of conveyance
     (ignoring and without reduction for the Environmental Liability with
     respect to such Affected Property) as agreed by the Shareholders and the
     Purchaser or, absent such agreement, determined pursuant to arbitration in
     accordance with the procedures set forth above in this Section 10.6(d),
     provided that (i) Shareholders fully indemnify the Companies, the
     Subsidiary and Purchaser (and the other Persons named as indemnitees in
     Section 10.6(a)) from and against any and all Environmental Liabilities
     attributable to the Affected Property, in the manner provided in this
     Section 10.6, and (ii) the conveyance of such Affected Property shall be
     by an instrument of assignment or conveyance which is expressly made
     without any warranty or representation, express or implied, as to title,
     condition or any other matter (except that the assignor shall make a
     limited warranty of title with respect to Title Defects created by,
     through or under any of the Companies or Subsidiary on or after the
     Closing Date only, and, to the extent transferable, with subrogation of
     Shareholders (or such designee) to all covenants and warranties
     theretofore made by the Companies' or Subsidiary's predecessors in title,
     except any subsidiary or Affiliate of the Companies or Subsidiary). In the
     event 


                                      75
<PAGE>   87

     Shareholders elect to submit to arbitration, any payment required to be
     made to Purchaser shall be made upon the conclusion of such arbitration
     proceeding, according to the Arbitrator's decision.

          (e) If any Environmental Liability requires corrective, remedial or
     other actions pursuant to Environmental Laws to respond to, remove, or
     otherwise address any conditions that cause, or contribute to, such
     Environmental Liability, the Purchaser shall cause the Companies to retain
     an environmental consultant approved by the Shareholders, which approval
     shall not be unreasonably withheld or delayed. The consultant shall
     prepare a remediation workplan, which shall be submitted to Shareholders,
     as shall each amendment and supplement thereto which requires the
     expenditure of material additional costs. Shareholders shall have ten (10)
     Business Days after receipt of the workplan or such amendment or
     supplement (as the case may be) to dispute in writing the necessity or
     efficacy of any of the procedures or costs proposed therein, which writing
     shall specify the reasons for such dispute. If the Shareholders fail to
     give any notice of dispute within such ten (10) Business Day period, the
     workplan, amendment or supplement (as the case may be) shall be deemed
     accepted. If the Purchaser and the Shareholders cannot resolve such
     dispute, the dispute shall be submitted to arbitration in accordance with
     the procedures set forth in Section 9.2(b). In such event, the Purchaser
     shall have the right to cause the Companies or Subsidiary, as the case may
     be, to implement the workplan, including the disputed procedures. The
     Shareholders shall bear the cost of the non-disputed procedures as
     provided in this Section 10.6, and the Arbitrator shall determine which
     party shall bear the cost of the disputed procedures. The Arbitrator shall
     allocate responsibility for the costs of the disputed procedures by
     determining whether the disputed procedures were necessary to effect the
     remediation and were cost-effective. To the extent that the Arbitrator
     finds that a disputed procedure was required to effect the remediation but
     was not proposed to be conducted in a cost-effective manner, the
     Arbitrator shall impose on the Shareholders the cost of accomplishing the
     procedure in a cost-effective manner and upon the Purchaser, the balance
     of such cost. The foregoing notice, dispute and arbitration procedure
     shall be applicable to each material amendment and supplement to the
     original workplan. Periodically, the Purchaser shall report to the
     Shareholders the results of the corrective, remedial or other action and
     the actual costs expended. Upon the Shareholders' receipt of each workplan
     and each amendment or supplement to the workplan which requires the
     expenditure of material additional costs, the Shareholders shall have the
     elections pursuant to clauses (x) and (y) of Section 10.6(d); provided,
     however, that Shareholders' rights to make such election shall be deferred
     and the Purchaser shall not be obligated to deliver a workplan for any
     time periods during which the Companies are required to respond to an
     emergency situation or order of a Governmental Body which does not permit
     the Purchaser adequate time to prepare a workplan or allow the
     Shareholders to make such elections. In preparing each workplan and in
     conducting all corrective, remedial or other actions, the Purchaser shall
     cause the Companies to act in a reasonable and professional manner and
     will use their best efforts to implement and complete the corrective,
     remedial or other actions in a cost-effective manner. Subject to the


                                      76
<PAGE>   88

     foregoing, the Companies shall have sole and exclusive authority to
     conduct any negotiations with any Governmental Body or third party
     concerning the investigation, evaluation, selection and implementation of
     any such corrective, remedial or other actions. Shareholders shall have
     the right to participate in the planning and design of any such
     corrective, remedial or other actions by reviewing and commenting on a
     draft of any study, plan or report associated with such actions before the
     study, plan or report is submitted to the Governmental Body. In planning
     and designing any such study, plan or report and in considering
     Shareholders' comments, suggestions and requests with respect thereto, the
     Purchaser shall cause the Companies to give due consideration to the
     multiple goals of minimizing Environmental Liabilities (including the
     selection of remedies which reflect customary industry practices, are cost
     effective and consider all related business and time requirements) and
     fully complying with all Environmental Laws (including then-applicable
     Requirements of Laws). The Purchaser shall in good faith carefully
     consider each comment, suggestion or request made by Shareholders with
     respect to the draft study, plan or report and will cooperate with
     Shareholders by meeting periodically, at Shareholders' request, to discuss
     any such study, plan or report. Shareholders shall maintain in confidence
     all information provided by the Companies, the Subsidiary or Purchaser at
     any such meeting except to the extent such information is otherwise
     available to the general public or is information Shareholders are legally
     required to disclose. In addition, the Purchaser shall provide
     Shareholders copies of all reports, plans and correspondence submitted to
     any Governmental Body with respect to such actions. Further, the Purchaser
     shall provide Shareholders three days' notice (or shall provide
     Shareholders notice as soon as practical if three days' notice is not
     practical) of any formal meetings with, hearings before, or other formal
     sessions with any Governmental Body which are expected to result in
     decisions regarding actions to be required by the Governmental Body that
     concern Environmental Liabilities for which Shareholders may be
     responsible. Shareholders may attend such formal meetings, hearings or
     other formal sessions, but Shareholders may not negotiate with any
     Governmental Body or third party concerning the investigation, evaluation,
     selection, or implementation of any above-referenced corrective, remedial,
     or other actions necessary to respond to, remove, or otherwise address any
     such conditions that cause, contribute to, or are associated with any such
     Environmental Liability. Upon reasonable, periodic requests from
     Purchaser, Shareholders shall provide periodic payments to the Companies
     for expenses incurred by the Companies and the Subsidiary for such
     corrective, remedial, or other actions to the extent Shareholders have
     been afforded the new election options as set forth above, if applicable,
     and the rights to participate as contemplated by this Agreement.

     10.7 Notice of Claims.

          (a) Any indemnified party shall give to the indemnifying party a
     notice (a "Claim Notice") describing in reasonable detail the facts giving
     rise to any claim for indemnification hereunder and shall include in such
     Claim Notice (if then known) the amount or the method of computation of
     the amount of such claim, and a reference to 


                                      77
<PAGE>   89

     the provisions of this Agreement or any other agreement, document or
     instrument executed hereunder or in connection herewith upon which such
     claim is based; provided, that (a) a Claim Notice in respect of any action
     at law or suit in equity by or against a third Person as to which
     indemnification will be sought shall be given promptly after the action or
     suit is commenced; and (b) failure to give such notice shall not relieve
     the indemnifying party of its obligations hereunder except to the extent
     it shall have been prejudiced by such failure.

          (b) In calculating any Losses, there shall be deducted any insurance
     recovery in respect thereof (and no right of subrogation shall accrue
     hereunder to any insurer). To the extent that an indemnified party has
     insurance coverage with respect to any Loss or Environmental Liability, or
     is indemnified against any Loss or Environmental Liability by a Person
     other than the Shareholders, such indemnified party shall, and agrees that
     it will, seek to collect its damages first against such other Person and
     only secondarily from an indemnifying party, and in the event that any
     indemnifying party is required to indemnify any indemnified party for any
     such Loss or Environmental Liability, the indemnifying party shall have a
     right of subrogation with respect to such insurer or other Person.

          (c) After the giving of any Claim Notice pursuant hereto, the amount
     of indemnification to which an indemnified party shall be entitled under
     this Section 10.7 shall be determined: (a) by the written agreement
     between the indemnified party and the indemnifying party or, if such
     written agreement cannot be reached, (b) by a final judgment or decree of
     any court of competent jurisdiction or, to the extent provided herein, by
     arbitration. The judgment or decree of a court shall be deemed final when
     the time for appeal, if any, shall have expired and no appeal shall have
     been taken or when all appeals taken shall have been finally determined.

     10.8 Exclusive Remedies. Except as otherwise explicitly provided in this
Agreement or by statute to the extent that statutory remedies cannot legally be
waived by the Person entitled thereto, and except for fraud, deceit or
intentional misrepresentation by Purchaser or either Shareholder, after
consummation of the transactions contemplated by this Agreement the sole and
exclusive remedy of Purchaser and the Shareholders for breach of any of the
respective representations, warranties or covenants of Purchaser or either
Shareholder in this Agreement are as set forth in Sections 9.1, 9.2, and 9.3
and this Article X, provided that Purchaser and the Shareholders do not waive
any rights it or they may have to specific performance. Purchaser acknowledges
and agrees that neither of Shareholders would have entered into this Agreement
but for the inclusion herein of this Section 10.8.

                                  ARTICLE XI.
                                 MISCELLANEOUS

     11.1 Entirety. Each of Purchaser and Shareholders agrees that Purchaser
has made no express or implied agreements, representations or warranties to
Shareholders, and neither of Shareholders has made any express or implied
agreements, representations or warranties to Purchaser, in all cases relating
to the transactions contemplated by this Agreement, which are not expressly set
forth in this Agreement (including the Schedules hereto, the agreements
described therein and the Exhibits hereto). This Agreement embodies (including
the Schedules hereto, the agreements described therein and the Exhibits hereto)
the entire agreement between the parties hereto concerning the subject matter
hereof, and supersedes and cancels any express or implied prior agreement,
arrangement or understanding entered into between the parties hereto relating
to the subject matter hereof. This Agreement shall not be amended, modified or
supplemented except by a written instrument signed by an authorized
representative of each of the parties hereto.

     11.2 Counterparts. Any number of counterparts hereof may be executed and
each such counterpart shall constitute an original instrument, but all such
counterparts together shall constitute but one instrument.

     11.3 Notices and Waivers. Any notice, instruction, authorization, request
or demand required hereunder shall be in writing, and shall be delivered either
by personal delivery, by telegram, telex, telecopy or similar facsimile means,
by certified or registered mail, return receipt requested, or by courier or
delivery service, addressed to the parties hereto at the address indicated
beneath their respective signatures on the execution pages of this Agreement,
or at such other address and number as a party shall have previously designated
by written notice given to the other parties in the manner hereinabove set
forth. Receipt of notices shall constitute delivery; if sent by facsimile
means, confirmation of such receipt by confirmed facsimile transmission shall
constitute receipt of communications; and when delivered and receipted for (or
upon the date of attempted delivery where delivery is refused), if hand
delivered, sent by express courier or delivery service, or sent by certified or
registered mail, return receipt requested. In the event of any merger,
dissolution or other event pursuant to which the corporate existence of any
party hereto terminates, any notice, demand, claim or other communication
provided for in this Agreement may be given or delivered to any survivor or
successor to such party or all or any part of its assets. Any term or provision
of this Agreement may be waived, or the time for its performance may be
extended, by the party or parties entitled to the benefit thereof. Any such
waiver shall be validly and sufficiently given for the purposes of this
Agreement if, as to any party, it is in writing signed by an authorized
representative of such party. The failure of any party hereto to enforce at any
time any provision of this Agreement shall not be construed to be a waiver of
such provision, nor in any way to affect the validity of this Agreement or any
part hereof or the right of any party thereafter to enforce each and every such
provision. No waiver of any breach of this Agreement shall be held to
constitute a waiver of any other or subsequent breach.

representations, warranties, and conditions of this Agreement shall be binding
upon and shall inure to the benefit of and be enforceable by the parties
hereto, their respective successors and permitted assigns, but this Agreement
and the rights and obligations hereunder shall not be assignable or delegable
by any party; provided, however, that Purchaser shall be entitled to assign its
rights and delegate its duties hereunder to any corporate Affiliate of
Purchaser, but any such assignment shall not have the effect of terminating
Purchasers, or any subsequent assignors' duties or obligations as provided
herein.

     11.6 Severability. If any term, provision, covenant, or restriction of
this Agreement is held by the final, nonappealable order of a court of

FOR IMMEDIATE RELEASE
Wednesday, November 15, 1996

        KCS ENERGY, INC. SIGNS DEFINITIVE AGREEMENT TO ACQUIRE
       THE OIL AND GAS OPERATIONS OF MIDAMERICAN ENERGY COMPANY

HOUSTON, TX, November 15, 1996 -- KCS Energy, Inc. (NYSE: KCS) today announced
it has signed a definitive agreement to purchase InterCoast Oil and Gas Company
(formerly known as Medallion Production Company -- "Medallion"), the Tulsa,
Oklahoma-based oil and gas exploration and production subsidiary and two gas
marketing subsidiaries of MidAmerican Energy Company, for a purchase price of
$210 million in cash and 435,000 warrants to purchase KCS common stock.  The
warrants have a four-year term and an exercise price of $45 per share.  In
addition, the Company has entered into a separate agreement to acquire related
Section 29 credits for a net purchase price of approximately $4 million.  The
acquisition is expected to close before year end.

        As previously announced on November 5, 1996, the Company has filed a
registration statement with the Securities and Exchange Commission concerning
the proposed public sale of 3 million shares of its common stock. Net proceeds
to the Company will be used to repay a portion of the indebtedness expected to
be incurred to finance the acquisition.

        KCS is an independent energy company primarily engaged in the
acquisition, exploration, development and production of natural gas and crude
oil.  The Company also operates natural gas transportation and marketing 
businesses.

        A registration statement relating to these securities has been filed
with the Securities and Exchange Commission but has not yet become effective.
These securities may not be sold nor may offers to buy be accepted prior to the
time the registration statement becomes effective.  This release shall not
constitute an offer to sell or a solicitation to buy nor shall there be any
sale of these securities in any state in which such an offer, solicitation or
sale would be unlawful prior to registration or qualification under the
securities laws of any such state.
