ITEM 2.       ACQUISITION OR DISPOSITION OF ASSETS

         On June 6, 1996, Tejas Gas Corporation ("Tejas") acquired Transok, Inc.
("Transok") from Central and South West Corporation ("CSW") through a merger of
a recently formed wholly owned subsidiary of Tejas into Transok pursuant to an
Agreement of Merger dated May 9, 1996, between Tejas and CSW, as amended (the
"Merger Agreement"). The Merger Agreement is filed as Exhibit 2(a)to this
Current Report on Form 8-K and is incorporated herein by reference. Immediately
prior to the acquisition, Transok sold seven gas processing plants (the "Transok
Plants")to a third-party lessor (the"Lessor") which in turn leased these
facilities to Tejas pursuant to a Lease Agreement dated June 6, 1996 (the
"Lease"). The Lease and related documentation are filed as Exhibits 2(b) and
2(c) to this Form 8-K and are incorporated herein by reference.

         Transok, which was founded in 1955, operates intrastate natural gas
pipeline systems in Oklahoma, Louisiana and Texas and is the largest processor
of natural gas in Oklahoma. Transok's operations include (i) more than 6,500
miles of gathering and transmission pipelines in Oklahoma, Louisiana and Texas
with 2.3 billion cubic feet ("BCF") per day of pipeline capacity; (ii) eight
operating processing plants, of which seven are leased, with total capacity of
564 million cubic feet per day ("Mmcf/d") of natural gas; (iii) a 26
BCF-capacity natural gas reservoir storage facility with 300 Mmcf/d of
withdrawal and 200 Mmcf/d of injection capacity; and (iv) 1.4 trillion cubic
feet of connected third-party natural gas reserves. Transok's average system
throughput was 1.3 BCF per day during the first quarter of 1996 and 1.4 BCF per
day in 1995. Liquids production was 25,100 barrels per day during the first
quarter of 1996 and 22,400 barrels per day in 1995.

         The total purchase price received by CSW at closing was $690 million in
cash of which $565 million was paid by Tejas and $125 million was paid by the
Lessor to acquire the Transok Plants. In addition, Transok had outstanding at
the time of the acquisition $200 million principal amount of medium-term notes,
which remained in place following the merger. Tejas' financing for its cash
requirements consisted of (i) $178 million borrowed under an existing credit
facility of a wholly-owned Tejas subsidiary and (ii) $387 million, net of a
voluntary prepayment, borrowed under a new $425 million credit facility arranged
by Bank of Montreal and Canadian Imperial Bank of Commerce. The Lessor is
leasing the Transok Plants to Tejas for a five-year term with annual lease
payments of approximately $9 million. The Lease may be extended by Tejas for up
to two two-year terms with the approval of the Lessor and provides Tejas the
option to purchase the Transok Plants during the term. The option to purchase
all of the Transok Plants is exercisable for $125 million. If such purchase
option is not exercised, Tejas will be obligated to pay the Lessor a termination
fee of approximately $106 million at the end of the Lease. However, such fee
will be reduced by the excess, if any, of the proceeds from the Lessor's sale of
the assets over $19 million. The Lease also provides Tejas the option at any
time during the term to purchase such number of the Transok Plants as may be
purchased for an amount not exceeding approximately $31 million, with
corresponding reductions in the $106 million termination fee and $19 million
threshold amount. Tejas estimates that transaction costs associated with the
merger and related financing will total approximately $13 million.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Board of Directors of Transok, Inc.:

We have audited the accompanying consolidated balance sheet of Transok, Inc. (an
Oklahoma Corporation and a wholly owned subsidiary of Central and South West
Corporation) and subsidiaries as of December 31, 1995 and 1994, and the related
consolidated statements of income, cash flows and stockholder's equity for each
of the three years in the period ended December 31, 1995. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Transok, Inc., and subsidiaries
as of December 31, 1995 and 1994, and the results of their operations and their
cash flows for each of the three years in the period ended December 31, 1995, in
conformity with generally accepted accounting principles.

As discussed in Notes 3 and 7 to the consolidated financial statements, the
Company adopted Statement of Financial Accounting Standards No. 106, No. 109 and
No. 112 effective January 1, 1993.

TRANSOK, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


NOTE 1. TRANSACTIONS WITH AFFILIATES

         Transok, Inc. (the Company or Transok) is an intrastate natural gas
transmission, storage, marketing, gathering and processing company with
headquarters in Tulsa, Oklahoma. Incorporated in 1955, Transok was created to
supply natural gas to Public Service Company of Oklahoma (PSO) electric power
generation stations and has since expanded its operations to transport gas for
other parties, as well as engage in other services such as gas processing,
storage, gathering, compression, risk management and gas and liquids marketing.

         Transok is a wholly owned subsidiary of Central and South West
Corporation (CSW). On January 9, 1996, CSW announced it will explore strategic
alternatives for Transok, including a possible sale.

         As a wholly-owned subsidiary of CSW, a holding company subject to the
Public Utility Holding Company Act of 1935, Transok engages in transactions and
coordinates its activities and operations with other members of the CSW System,
principally PSO. The Company provides administrative services in support of
PSO's natural gas requirements. It further provides for the transportation of
PSO's natural gas fuel supply through the Company's gathering and transmission
system.

         The transportation and administration fees charged to PSO are
determined annually through a fully allocated cost of service study that
allocates costs to the Company's various business functions. In addition to
actual transportation and administration costs allocated to PSO, the Company is
permitted to earn a return on equity equal to the rate allowed PSO in its most
recent rate case before the Corporation Commission of the State of Oklahoma
(OCC). Revenues from transportation and administration services with PSO were
$31.8 million in 1995, $31.4 million in 1994 and $28.5 million in 1993.

         The Company also provides transportation services to West Texas
Utilities Company, (WTU) and Southwestern Electric Power Company, (SWEPCO).
Transportation fees charged to WTU and SWEPCO are based on the Company's cost of
providing service plus an equity return. Revenues from transportation fees
charged to WTU and SWEPCO were $3.0 million, $3.5 million and $.8 million in
1995, 1994 and 1993, respectively.

         The Company also makes gas sales to CSW affiliates. Gas sales to PSO
were $77.6 million, $76.9 million and $54.4 million in 1995, 1994 and 1993,
respectively. Gas sales to other members of the CSW system were $16.8 million,
$14.4 million and $17.7 million in 1995, 1994 and 1993, respectively. All sales
made to PSO and other members of the CSW system are made at cost and therefore
have no impact on the Company's net financial results of operations.

         The Company, together with other members of the CSW System, has
established a money pool to coordinate short-term borrowings from banks and
through the issuance of commercial paper. Money pool balances are shown as
advances from and to affiliates on the consolidated balance sheets. Funds
borrowed from, or loaned to, the money pool are charged, or earn, interest in
accordance with the money pool arrangement. The Company incurred net interest
costs of $0.5 million, $1.3 million and $1.3 million under the money pool
arrangement in 1995, 1994 and 1993, respectively. The Company is authorized to
borrow up to $200 million under this arrangement.

                                       10

         Central and South West Services, Inc., performs, at cost, certain
accounting, tax, legal, financial, electronic data processing and other services
for the Company. Costs incurred to provide such services are allocated to
Transok and other CSW affiliates based on various formulas. Amounts charged to
expense were $3.6 million, $4.8 million and $3.6 million in 1995, 1994 and 1993,
respectively.

         The Company sells selected accounts receivable, without recourse, to
CSW Credit, Inc., a wholly owned subsidiary of CSW. At December 31, 1995 and
1994, the Company had $79.7 million and $42.9 million in outstanding receivables
which had been sold to CSW Credit, Inc.


NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         PRINCIPLES OF CONSOLIDATION - The consolidated financial statements
include the accounts of the Company and its subsidiary companies. All
significant intercompany balances and transactions have been eliminated.

         ESTIMATES - The preparation of 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 assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period.
Actual results could differ from those estimates.

         PARTNERSHIPS - The Company accounts for its partnership interests using
the equity method of accounting.

         PROPERTY, PLANT AND EQUIPMENT - Gas plant acquisitions are stated at
fair market value based on the purchase price while other gas plant is stated at
the original cost of construction, which includes the cost of contracted
services, direct labor, materials, overhead items and capitalized interest.

         DEPRECIATION AND AMORTIZATION - Provisions for depreciation of gas
plant are computed using the half-year convention straight-line method,
generally at individual rates applied to the various classes of depreciable
property. The annual consolidated composite rates averaged 3.6%, 3.2% and 3.4%
for 1995, 1994 and 1993.

         Amortization of the Tranpache investment is based on the Company's
interest in the Tranpache properties and the expected life of the investment.
The average annual amortization rates for 1995, 1994 and 1993 were 12.3%, 24.0%
and 26.6%, respectively.

         STATEMENTS OF CASH FLOWS - Cash equivalents are considered to be highly
liquid debt instruments purchased with a maturity of three months or less.
Accordingly, temporary cash investments are considered cash equivalents.

         NEW ACCOUNTING STANDARDS - Effective January 1, 1995, the Company
adopted Statement of Financial Accounting Standards (SFAS) No. 116, Accounting
for Contributions Made and Contributions Received. This statement establishes
accounting standards for contributions and applies to all entities that either
receive or make contributions. Contributions made, including unconditional
promises to give, must be recognized as expenses in the period made at fair
market value. Conditional promises to give must be recognized when they become
unconditional, that is, when the conditions of the gift are substantially met.
The impact of adopting this statement in 1995 was not material.

                                       11

         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, to be effective for financial statements
for fiscal years beginning after December 15, 1995. The Statement establishes a
two fold test for identification and quantification of an impairment. The first
test in determining an impairment is to compare the sum of expected future cash
flows (undiscounted and without interest charges) to the carrying value of the
asset. If the sum of expected cash flows are not sufficient to recover the
carrying value of the asset, then an impairment is recognized. Once an
impairment is identified, the second part of the test is applied to quantify the
value of the impairment. The statement lists several alternative methods of
establishing fair market value and quantifying the impairment.

         Transok will adopt SFAS No. 121 effective January 1, 1996. The Company
is not aware of any assets which would currently meet the test for impairment.

         In October 1993, the FASB issued FAS No. 123, Accounting for Stock
Based Compensation, with an effective date for transactions entered into after
December 15, 1995. The Statement requires the use of an option pricing model to
calculate the value of stock-based transactions where such value cannot
otherwise be determined, but then allows for two options on how this value is
utilized. One method recognizes this value as a cost of compensation and as an
expense for the current period. The alternative allows for only footnote
disclosure of the compensation cost, without actually charging the amount
against current earnings.

         As provided by the provisions of SFAS No. 123, Transok will continue to
apply the recognition and measurement provisions of Accounting Principles Board
Opinion No. 25, "Accounting for Stock Issued to Employees" and adopt the
disclosure requirements of SFAS No. 123 in 1996. Accordingly, the adoption of
SFAS No. 123 will not impact Transok's consolidated results of operations or
financial condition.

         PRICE RISK MANAGEMENT ACTIVITIES - The Company periodically uses
natural gas futures, options and basis swap contracts to manage the impact of
price fluctuations on its inventory of natural gas, fuel and shrinkage
requirements for its processing plants and certain fixed price purchase and
sales contracts. Such contracts are designated at inception as either a hedge,
when there is a direct relationship to the price risk associated with the
Company's operations, or as a speculative contract where there is no such
relationship. Gains and losses on hedge contracts are deferred until the effect
of the corresponding hedged transaction is recognized. For those contracts that
are not designated as hedges, changes in the fair value of those contracts are
recognized as gains or losses in income currently and are recorded in the
balance sheet at fair value at the reporting date. The Company determines the
fair value of its contracts based upon settlement prices for exchange-traded
contracts, market-related indexes or by obtaining quotes from brokers (see Note
9, "Price Risk Management Activities").

         INVENTORIES - Gas stored underground represents gas stored in
Company-owned storage facilities as well as off-system storage facilities and
includes gas anticipated to be withdrawn in the next year. The non-current
portion of gas stored underground represents that quantity of gas in storage
that the Company does not anticipate using within the next year and is
classified as deferred charges and other assets. All inventories are valued at
the lower of average cost or market.

         RECLASSIFICATION - Certain financial statement items for prior years
have been reclassified to conform to the 1995 presentation.

                                       12

NOTE 3.       FEDERAL AND STATE INCOME TAXES

         The Company, together with other members of the CSW System, files a
consolidated Federal income tax return.

         The Company adopted SFAS No. 109, Accounting for Income Taxes,
effective January 1, 1993. The cumulative effect of adopting SFAS No. 109 on the
Company's financial statements was to increase 1993 net income by $7.0 million,
of which, federal deferred income taxes were reduced by $8.7 million and state
deferred taxes were increased by $1.7 million.

         Deferred income taxes reflect the net tax effect of temporary
differences between the carrying amounts of assets and liabilities for financial
reporting purposes and the amounts used for income tax purposes. The tax effects
of significant items comprising the Company's net deferred tax liability at
December 31, 1995 and 1994 are as follows:
                                                               1995       1994

NOTE 4.       LONG-TERM DEBT

         In 1993 and 1992 the Company sold $60 million and $140 million,
respectively, of medium-term notes maturing from 1999 to 2023 under its $200
million private placement medium-term note program. Proceeds from the sale of
these notes were used primarily to repay interim financing provided by CSW in
1991 and 1992 for acquisitions made by the Company. The weighted average
interest rate of the notes was 7.7% at December 31, 1995 and 1994. The long-term
debt outstanding at the end of December 31, 1995 and 1994 was as follows:

million and $12.8 million during 1995, 1994 and 1993, respectively.


NOTE 6.       FINANCIAL INSTRUMENTS

         The following methods and assumptions were used to estimate the fair
value of each class of financial instruments for which it is practicable to
estimate fair value.

         CASH AND SHORT-TERM INVESTMENTS - The carrying amount approximates fair
value because of the short maturity of those instruments.

         LONG-TERM DEBT - The fair value of the Company's long-term debt is
estimated based on the quoted market prices for the same or similar issues or on
the current rates offered to the Company for debt of the same remaining
maturities.

         The estimated fair values of the Company's financial instruments at
December 31 are as follows:

                                              1995                  1994

NOTE 7.       BENEFIT PLANS

         DEFINED BENEFIT PENSION PLAN - The Company, together with other members
of the CSW System, maintains a tax qualified, non-contributory defined benefit
pension plan covering substantially all its employees. Benefits are based on
employees' years of credited service, age at retirement and final average annual
earnings with an offset for the participant's primary Social Security benefit.
The CSW System's funding policy is based on actuarially determined
contributions, taking into account amounts which are deductible for income tax
purposes and minimum contributions required by the Employee Retirement Income
Security Act of 1974, as amended. Contributions to the plan for the years ended
December 31, 1995, 1994 and 1993 were $2.0 million, $1.8 million and $1.8
million, respectively. Pension plan assets consist primarily of common stocks
and short-term and intermediate-term fixed income investments.

         The components of net periodic pension cost and the assumptions used in
accounting for pensions are as follows:

         At December 31, 1995, the plan's net assets were approximately equal to
the total actuarial present value of the accumulated benefit obligation. No
reconciliation of the funding status of the plan is presented because such
information is available.

         POSTRETIREMENT BENEFITS OTHER THAN PENSIONS - The Company adopted SFAS
No. 106, Employers' Accounting for Postretirement Benefits Other Than Pensions,
January 1, 1993. The Company's accumulated postretirement benefit obligation was
$5.2 million at December 31, 1995 and $4.7 million at December 31, 1994. CSW
System's funding policy is based on actuarially determined contributions, taking
into account amounts which are deductible for income tax purposes. The Company
contributed $807,000 in 1995, $934,000 in 1994 and $874,000 in 1993.

         The following assumptions were used in accounting for SFAS No. 106:

                                       17

         Health Care Cost Trend Rate Assumptions:

Pre-65 Participants:

         1995 rate of 10.00% grading down .75% per year to an ultimate rate of
6.0% in 2001.
         1994 rate of 11.75% grading down .75% per year to an ultimate rate of
6.5% in 2001.

Post-65 Participants:

         1995 rate of 10.00% grading down .75% per year to an ultimate rate of
5.5% in 2001.
         1994 rate of 11.25% grading down .75% per year to an ultimate rate of
6.0% in 2001.

         Upon implementation of SFAS No. 106 in 1993, the CSW System decided to
amortize the transition obligation over a 20 year period.

         Increasing the assumed health care cost trend rates by one percentage
point in each year would increase the accumulated postretirement benefit
obligation as of December 31, 1995 by $740,000 and increase the aggregate of the
service and interest cost components of net postretirement benefits by $168,000.

         POSTEMPLOYMENT BENEFITS - In November 1992, the FASB issued SFAS No.
112, Employers' Accounting for Postemployment Benefits. This statement required
the accrual method of accounting for certain types of postemployment benefits
provided to former or inactive employees after employment, but before
retirement. This standard required that the expected cost of these benefits be
accrued during the period employees render service to qualify for benefits. The
most significant costs for the Company are the continued medical and salary
benefits during long-term disability. Effective January 1, 1993 the Company
adopted SFAS No. 112 and the effect of the change on 1993 income was $273,000,
net of taxes of $173,000 reflected in cumulative effect of changes in accounting
principles.

NOTE 8.       RENTAL AND LEASE COMMITMENTS

         The Company leases certain land, facilities and equipment under various
cancelable and non-cancelable operating leases. During 1993, the Company entered
into a long-term operating lease arrangement to lease all the pipeline
facilities of Palo Duro Pipeline Company (Palo Duro). The agreement, which
includes provisions to purchase the leased pipeline assets, provides for an
initial term of five years with several options to extend the lease for up to an
additional seventeen years.

         Total rental charges to operating expenses for the year ended December
31, including the Palo Duro lease noted above, were as follows:

                          (millions)
- ------------------------------------
1993                        $  2.5
1994                        $  3.7
1995                        $  3.7
- ------------------------------------

                                       18

         Minimum rental commitments as of December 31, 1995 for all
non-cancelable leases are:

- -----------------------------------
1996                        $  4.3
1997                        $  4.7
1998                        $  3.3
1999                        $  3.3
2000                        $  3.2
Thereafter                  $ 17.9
- -----------------------------------

NOTE 9.       PRICE RISK MANAGEMENT ACTIVITIES

         HEDGING ACTIVITIES - The Company uses natural gas futures, options and
basis swaps to reduce its price risk exposure arising from the purchase and sale
of natural gas. Natural gas futures and options allow the Company to protect
against volatility in supply cost in fulfilling fixed price sales contracts,
meeting storage requirements and purchasing natural gas for processing
operations. Natural gas futures and options are also used to protect the Company
against price exposure on sales of natural gas from storage or fixed price
purchase agreements. In addition, basis swaps protect the Company against
volatility in price differentials between geographic areas. At December 31, 1995
and 1994, the Company had deferred gains (losses) of $(0.5) million and $1.9
million, respectively, from these transactions.

         The following table presents the Company's net open positions at
December 31 for the financial instruments described above:

NOTE 10.      LITIGATION AND REGULATORY PROCEEDINGS

         On October 30, 1992, Transok filed with the Federal Energy Regulatory
Commission ("FERC") a rate case in Docket No. PR93-4 for approval of cost of
service rates for Section 311 transportation on the Traditional System. On
September 18, 1995, the FERC approved a settlement of Transok's rate case. The
settlement provided for maximum rates of $2.7360 per MMBtu and $0.1045 per MMBtu
for firm reservation and firm usage charges, respectively, $0.1945 per MMBtu for
interruptible and an allowance of 1.7% of the gas received for fuel use and lost
and unaccounted for gas. These rates were effective from November 1, 1992, until
October 31, 1995, when Transok was required to file a new rate case. On November
17, 1995, Transok filed with the FERC a Refund Report indicating that it had
made refunds to its shippers of approximately $900,000 as the difference between
what it had collected from Section 311 shippers and the approved rates during
their effective time period plus interest.

         On November 1, 1995, Transok filed with the FERC a rate case in Docket
No. PR96-2 for approval of cost of service rates for Section 311 transportation
on the Traditional System. Transok requested approval of maximum rates of $2.736
per MMBtu and $.1751 per MMBtu for firm reservation and firm usage charges,
respectively, $0.265 per MMBtu for interruptible plus the shipper's pro rata
share of compressor fuel and 0.5% of the volumes transported as an allowance for
lost and unaccounted for gas. Transok also informed the FERC in the case that it
was ceasing to offer new firm transportation service and was seeking approval of
the above firm rates only for the purpose of collecting the rates contained in
firm transportation contracts still in effect as of November 1, 1995. Ten
parties have intervened in the rate case. This matter is presently pending
before the FERC, and therefore, the outcome is not ascertainable at this time.

         Transok's Greasy Creek storage facility located on the Traditional
System is currently approved by the FERC to charge market based rates for up to
4.0 Bcf of the facility's capacity. The rates are effective for an indefinite
time period, subject to Transok informing the FERC if it becomes affiliated with
a local distribution company outside of the State of Oklahoma.

         Transok's Anadarko System in Oklahoma is currently authorized to
collect a maximum rate of $0.145 per MMBtu for Section 311 interruptible
transportation, plus each shipper's pro rata share of compressor fuel and 0.5%
of the volumes transported as an allowance for lost and unaccounted for gas.
Transok is required to file a new rate case with the FERC covering this system
on or before May 1, 1996.

         Transok's North Louisiana System is currently authorized to collect a
maximum rate of $0.1866 per MMBtu for Section 311 interruptible transportation,
plus the shipper's pro rata share of compressor fuel and 0.5% of the volumes
transported as an allowance for lost and unaccounted for gas. Transok is
required to file a new rate case with the FERC covering this system on or before
November 1, 1996.

                                       20

         Transok leases the Palo Duro pipeline system in Texas that provides
transportation service both in intrastate commerce and under Section 311 of the
Natural Gas Policy Act. On April 29, 1994, Transok filed an Application for
Review of Reasonableness of Transportation Rates for the Palo Duro system with
the Texas Railroad Commission proposing a maximum rate of $0.20 per MMBtu (plus
taxes) plus the shipper's pro rata share of compressor fuel and lost and
unaccounted for volumes. The matter is still pending before the Railroad
Commission and the ultimate outcome of this filing is unknown at this time.

         The Company, which provides natural gas services to PSO, and PSO have
been named defendants in various lawsuits filed in federal and state courts of
Oklahoma and Texas in 1984 through January 1995 by gas suppliers alleging claims
arising out of certain gas purchase contracts. Cases currently pending seek
approximately $1 million in actual damages, together with claims for punitive
damages which, in compliance with pleading code requirements, are alleged to be
in excess of $10,000. The plaintiffs seek relief through the filing dates as
well as attorney fees. As a result of settlements among the parties, certain
plaintiffs dismissed their claims with prejudice to further action. The
settlements were funded by PSO and did not have a significant effect on the
Company's consolidated results of operations. The remaining suits are in
preliminary stages. Management believes the ultimate resolution of the remaining
complaints will not have a significant effect on the Company's consolidated
financial position or results of operations. The Company is indemnified pursuant
to an agreement with PSO for any loss or costs that may be incurred by the
Company involving PSO gas supply contracts.

         The Company's compressor engines and other emission sources are subject
to air permit requirements, including monitoring. As a result of Clean Air Act
amendments, the Company may become subject to additional permit requirements in
the future, including compliance assurance monitoring, at eight facilities.
Should these sites become subject to additional permit requirements, it is not
expected to have a material adverse effect on the Company's consolidated
financial position or results of operations.

         The Company is party to various other legal claims, actions and
complaints arising in the normal course of business. Management does not expect
disposition of these matters to have a material adverse effect on the Company's
consolidated financial position or results of operations.

              UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS

                                  INTRODUCTION

         The following unaudited pro forma consolidated statements of earnings
for the year ended December 31, 1995 and the three-month period ended March 31,
1996 and the unaudited pro forma consolidated balance sheet as of March 31, 1996
(the "Pro Forma Consolidated Financial Statements") give effect to (i) the
Transok, Inc. acquisition under the purchase method of accounting and the
related assumptions and adjustments described in the notes to the Unaudited Pro
Forma Consolidated Financial Statements and, (ii) the net borrowing by Tejas of
its cash requirements of approximately $583 million, including related financing
costs, to finance the Transok, Inc. acquisition.

         The Pro Forma Consolidated Financial Statements are based upon the
historical audited and unaudited consolidated financial statements of Tejas and
Transok, Inc. and should be read in conjunction with the audited financial
statements and notes thereto included in Tejas' Annual Report on Form 10-K for
the year ended December 31, 1995, the unaudited Tejas' Quarterly Report on Form
10-Q for the three months ended March 31, 1996, and the audited and unaudited
financial statements and notes thereto of Transok, Inc. included in this current
report. Because of the seasonal nature of Tejas' and Transok's operations, among
other factors, the results of the interim period presented is not necessarily
indicative of the results to be expected of an entire year.

         The unaudited pro forma consolidated statements of earnings for the
year ended December 31, 1995 and the three months ended March 31, 1996 were
prepared assuming that the transactions described above were consummated as of
the beginning of each period presented. The unaudited pro forma consolidated
balance sheet as of March 31, 1996 was prepared assuming that the transaction
described above was consummated as of March 31, 1996. The Pro Forma Consolidated
Financial Statements have been prepared based upon assumptions deemed
appropriate by Tejas and may not be indicative of actual results.

                              TEJAS GAS CORPORATION
               NOTES TO UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL
                   STATEMENTS For the Year Ended December 31,
                                  1995 and the
                        Three Months Ended March 31, 1996

1.   BASIS OF PRESENTATION

         The Unaudited Pro Forma Consolidated Balance Sheet is presented
assuming the combination occurred on March 31, 1996. The Unaudited Pro Forma
Consolidated Statements of Earnings for the year ended December 31, 1995 and the
three months ended March 31, 1996 are presented as if the combination occurred
at the beginning of each period presented. The Pro Forma Consolidated Financial
Statements may not necessarily be indicative of the results which would actually
have occurred if the combination had been in effect on the date or for the
periods indicated or which may result in the future.

         While the 1996 first quarter pro forma statement of earnings indicates
a 32% improvement over the historical Tejas' 1996 first quarter, Tejas does not
anticipate the improvement created by the merger for the full year 1996 to be
significantly greater than the pro forma improvement reflected for the year
ended December 31, 1995.1 Projected improvements versus those anticipated for
Tejas before the merger are not expected to be substantial until the completion
of the capital expenditure programs related to the west to east movement of
natural gas on the Transok system. Under current plans, these programs will be
completed by the end of 1997. Tejas believes that the improvements from these
capital expenditures and the enhanced ability to market gas within the state of
Oklahoma will result in Transok making a significant contribution to Tejas'
consolidated earnings beginning in 1998.

         Since Tejas plans to reinvest the majority of the available free cash
flow on capital expenditures for the remainder of 1996 and 1997, Tejas
anticipates the issuance of at least $100 million of common equity and is also
reviewing a number of other alternatives to reduce leverage of Tejas from the
74% debt to total capitalization reflected on the pro forma balance sheet for
March 31, 1996 to a range approaching 60% by year end 1996 or mid year 1997.

2.   PRO FORMA ADJUSTMENTS - STATEMENTS OF EARNINGS

         The pro forma adjustments to the Unaudited Pro Forma Consolidated
Statements of Earnings reflect the following:

         (a) OPERATING EXPENSES - Through the consolidation and realignment of
operations and field- based personnel (a reduction of personnel from
approximately 540 at December 31, 1995 to approximately 480 at June 6, 1996),
Tejas anticipates a reduction of Transok's historical operating, general and
administration costs. Such reductions amount to approximately $2.8 million for
the year ended December 31, 1995 and approximately $0.7 million for the quarter
ended March 31, 1996. Offsetting these reductions is an increase in rental
expense associated with the lease of seven Transok gas processing plants. The
rental expense for the twelve month period is $9.8 million and the expense for
the three
- --------
     1 The statements included herein regarding future financial performance and
results and the other statements that are not historical facts are
forward-looking statements. The words "expect," "project,""estimate," "predict,"
"anticipate" and similar expressions are also intended to identify
forward-looking statements. Such statements involve risks, uncertainties and
assumptions, including but not limited to, industry conditions, stock market
conditions, prices of natural gas and other factors discussed in this Form 8-K
and in the Company's other filings with the Securities and Exchange Commission.
Should one or more of these risks or uncertainties materialize, or should
underlying assumptions prove incorrect, actual outcomes may vary materially from
those indicated.

                                       26
<PAGE>

month period is $2.4 million, including in both periods amortization of
associated costs. Additionally, this pro forma statement of earnings reflects a
1995 reclassification of $.9 million from operating expense to depreciation
expense to reflect Transok's change in presentation of financial data related to
depreciation of transportation equipment.

         (b) GENERAL AND ADMINISTRATIVE EXPENSES - A significant portion of the
historical amounts incurred by Transok for general and administrative expenses
represent parent company allocations. Based on Tejas' projected actual cost of
providing such incremental corporate services, the historical amounts have been
reduced by $2.4 million and $.6 million for the 1995 annual period and the 1996
three-month period, respectively. In addition, general and administrative
expenses have been reduced by $2.8 million for the year ended December 31, 1995
and $0.7 million for the three months ended March 31, 1996 to reflect personnel
and other cost reductions.

         (c) DEPRECIATION AND AMORTIZATION - The adjustment reflects the pro
forma depreciation and amortization expense based on the use of adjusted asset
lives and salvage value, straight-line method of depreciation for all assets and
the allocation of the purchase price.

         (d) INTEREST EXPENSE - The adjustment for interest expense reflects
interest computed on the additional indebtedness incurred for the purchase of
Transok. The principal amount of indebtedness incurred was approximately $582.8
million and the interest rate used to calculate the interest expense was 7.5%.
Interest expense also includes amortization of financing costs.

         (e) FACTORING EXPENSE - Transok has historically factored a portion of
its accounts receivable balances to its parent company in order to obtain
greater liquidity. Since accounts receivable will no longer be factored, a pro
forma adjustment has been made to reverse the factoring expense of $4.8 million
for the 1995 annual period and $1.8 million for the 1996 three-month period.

         (f) INCOME TAXES - The adjustment for income taxes represent the tax
effect of the foregoing pro forma adjustments computed at a 39% statutory income
tax rate which reflects both federal and state income tax rates. The reduction
of income taxes resulting from the pro forma adjustments is classified as
deferred on the income statement due to Tejas' alternative minimum tax position
during the pro forma periods.

3.   PRO FORMA ADJUSTMENTS - BALANCE SHEET

         The pro forma adjustments to the Unaudited Pro Forma Consolidated
Balance Sheet reflect the following:

         (g) DEFERRED CREDITS AND OTHER LIABILITIES - A $2.5 million liability
has been recorded to reflect management's current intent to (i) exercise a
purchase option on an office building that Transok is currently leasing and (ii)
subsequently sell the building for an estimated $2.5 million loss.

         (h) NET WORKING CAPITAL ADJUSTMENT - The adjustment reflects a $30.7
million working capital contribution by CSW as required by the terms of the
Merger Agreement.

         (i) ALLOCATION OF PURCHASE PRICE - Total cash consideration to be paid
by Tejas for the Transok, Inc. acquisition, plus related transaction costs, was
$582.8 million. In addition, Tejas assumed $200.0 million of Transok's
outstanding debt. The adjustments reflect the recording of the acquisition using
the purchase method of accounting and the allocation of the purchase price based
on the fair value of the

                                       27

<PAGE>

assets and liabilities acquired. The allocation of the purchase price is
preliminary, as valuation and other studies have not been finalized. It is not
expected that the final allocation of the purchase price will produce materially
different results from those presented herein. The adjustments also take into
consideration the sale by Transok to a third party of seven Transok gas
processing plants, immediately prior to the acquisition, and the leasing of
those plants by Tejas.

         (j) LONG-TERM DEBT - Adjustment to record borrowings associated with
the cash consideration paid to purchase Transok. Of the total cash consideration
of approximately $582.8 million, including transaction costs; $401.9 million was
obtained through the new credit facilities and $180.9 million was obtained under
the existing credit facilities of Tejas Gas and Acadian.

         by deed or otherwise, in any of the Constituent Corporations shall not

         unchanged).

                  common stock, par value $100.00 per share, of the Merger

consolidated financial position of the Company as of the respective dates of the
balance sheets included therein and (b) the consolidated results of the
operations of the Company for the fiscal years ended on such dates, all in
conformity with GAAP throughout the periods involved. Except as set forth in the
Seller's Disclosure Letter, there exist no liabilities or obligations of the
Company that are Material to the Company, whether accrued, absolute, contingent
or threatened, which would be required to be reflected, reserved for or
disclosed under GAAP in the consolidated financial statements of the Company as
of and for the period ended on the date of this representation and warranty,
other than (i) liabilities or obligations which are adequately reflected,
reserved for or disclosed in the Consolidated Financial Statements, and (ii)
liabilities or obligations incurred in the ordinary course of business of the
Company since December 31, 1995.

         Section 4.05.     NO MATERIAL ADVERSE EFFECT; CONDUCT.

                  (a) Since December 31, 1995, no event (other than any event
         that is of general application to all or a substantial portion of the
         Company's industry and other than any event that is expressly subject
         to any other representation or warranty contained in Articles III or
         IV) has, to the Knowledge of the Seller, occurred that, individually or
         together with other similar events, could reasonably be expected to
         constitute or cause a Material Adverse Effect on the Company.

                  (b) Except as disclosed in the Seller's Disclosure Letter,
         during the period from December 31, 1995 to the execution of this
         Agreement by the Seller, neither the Company nor any of its
         subsidiaries has engaged in any conduct that is proscribed during the
         period from the execution of this Agreement by the Seller to the
         Closing by subsections (a) through (j) of Section 6.02 or agreed in
         writing or otherwise during such period prior to the execution of this
         Agreement by the Seller to engage in any such conduct.

         Section 4.06.     TITLE TO PROPERTIES.

                  (a) The Company or its subsidiaries, individually or together,
         have indefeasible title to all of the properties reflected in the
         Consolidated Balance Sheet, (other than the Pipeline Assets, as to
         which they have such title or interest as is sufficient to enable the
         Company and its subsidiaries to conduct their business as currently
         conducted without material interference, and other than any properties
         reflected in the Consolidated Balance Sheet that (i) have been sold or
         otherwise disposed of since the date of the Consolidated Balance Sheet
         without breaching either Section 4.05(b) or Section 6.02(f) or (ii) are
         not, individually or in the aggregate, Material to the Company) free
         and clear of Liens, other than (x) Liens the existence of which is
         reflected in the Consolidated Financial Statements, (y) Permitted
         Encumbrances and (z) Liens that, individually or in the aggregate, are
         not Material to the Company. The Company or its subsidiaries,
         individually or together, hold under valid lease agreements all real
         and personal properties reflected in the Consolidated Balance Sheet as
         being held under capitalized leases, and all real and personal property
         that is subject to the operating leases to which reference is made in
         the notes to the Consolidated Financial Statements, and enjoy peaceful
         and undisturbed possession of such properties under such

                                       -8-

         leases, other than (i) any properties as to which such leases have
         terminated in the ordinary course of business since the date of the
         Consolidated Balance Sheet and (ii) any properties that, individually
         or in the aggregate, are not Material to the Company. Neither the
         Company nor any of its subsidiaries has received any written notice of
         any adverse claim to the title to any properties owned by them or with
         respect to any lease under which any properties are held by them, other
         than any claims that, individually or in the aggregate, could not
         reasonably be expected to have a Material Adverse Effect on the
         Company.

                  (b) EASEMENTS. Neither the Company nor any of its subsidiaries
         is in violation of the terms of any Easement except any such violations
         that, individually or in the aggregate, could not reasonably be
         expected to have a Material Adverse Effect on the Company. All
         Easements that are Material to the Company are valid and enforceable
         and grant the rights purported to be granted thereby and all rights
         necessary thereunder for the current operation of the business of the
         Company and its subsidiaries. There are no spatial gaps in the
         Easements that could reasonably be expected to have a Material Adverse
         Effect on the Company, and all parts of the Pipeline Assets that are
         Material to the Company are located either on property owned in fee by
         the Company or a subsidiary of the Company or on property subject to an
         Easement in favor of the Company or a subsidiary of the Company.

         Section 4.07.     CERTAIN OBLIGATIONS.

                  (a) Except as set forth in Section 4.07(a) of the Seller's
         Disclosure Letter, neither the Company nor any of its subsidiaries is a
         party to or bound by any Material Contract. Except as set forth in
         Section 4.07(a) of the Seller's Disclosure Letter, all Material
         Contracts are in full force and effect, the Company or the subsidiary
         of the Company that is a party to or bound by such Material Contract
         has performed its obligations thereunder to date and, to the Knowledge
         of the Seller, each other party thereto has performed its obligations
         thereunder to date, other than any failure of a Material Contract to be
         in full force and effect or any nonperformance thereof that could not
         reasonably be expected to have a Material Adverse Effect on the
         Company. Each of the Medium-Term Notes issued by the Company pursuant
         to the Medium-Term Note Program identified in Section 4.07(a) of the
         Seller's Disclosure Letter conform in all material respects to the
         sample Medium-Term Note included in Section 4.07(a-l) of the Seller's
         Disclosure Letter.

                  (b) Subject to Section 4.08(a), except for matters that could
         not reasonably be expected to have a Material Adverse Effect on the
         Company, no provision of any Law, Regulation or Order applicable to the
         Company or any of its subsidiaries (i) would preclude the Company or
         any of its subsidiaries from charging and collecting, without the
         necessity for approvals of any Governmental Authority and without
         refund obligation, market based rates for storing, processing,
         purchasing, gathering or selling Hydrocarbons; (ii) would preclude the
         Company or any of its subsidiaries from constructing additions to,
         modifications of or interconnections with third parties with respect
         to, its transportation, storage, processing or gathering facilities; or
         (iii) could reasonably be expected to require the Company or any of its
         subsidiaries to make refunds of amounts collected for sales or
         services.

                                       -9-

                  (c) Except as set forth in Section 4.07(c) of the Seller's
         Disclosure Letter and for matters that could not reasonably be expected
         to have a Material Adverse Effect on the Company, none of the Company
         and its subsidiaries engages in any natural gas or other futures or
         options trading or is a party to any price swaps, hedges, futures or
         similar instruments, except for transactions and agreements entered
         into primarily to hedge contracts for the purchase or sale of
         Hydrocarbons to which the Company or one of its subsidiaries is a
         party. Section 4.07(c) of the Seller's Disclosure Letter sets forth a
         true and correct statement of the position, as of the date hereof, of
         the Company and its subsidiaries with respect to obligations under
         Fixed Price Contracts (including, with respect to each Fixed Price
         Contract, location of delivery and variations in the obligation to take
         or deliver) and related Hydrocarbon price swaps, hedges, futures or
         similar instruments to which the Company or any of its subsidiaries is
         a party and that are Material to the Company.

         Section 4.08.     REGULATION; PERMITS AND LICENSES.

                  (a) The Company and its subsidiaries operate intrastate
         pipelines with Pipeline Assets located in the States of Texas,
         Oklahoma, and Louisiana. As such, the natural gas storage,
         transportation, and exchange services performed in interstate commerce
         by the Company and certain of its subsidiaries are subject to the
         provisions of either a limited jurisdiction certificate issued under
         the NGA or Section 311 of the NGPA ("Section 311") and the applicable
         Regulations of the FERC promulgated thereunder (including applicable
         facilities construction, rate authorization, reporting and refund
         requirements), as the provisions of such certificate, Section 311 and
         such Regulations may be interpreted, amended or modified from time to
         time pursuant to Orders of the FERC or of any Court. Under such Laws
         and Regulations, the Company and certain of its subsidiaries are
         authorized to charge market based rates for Section 311 storage
         services and are authorized to charge various maximum rates for Section
         311 transportation and exchange services. Except as set forth in
         Section 4.08(a) of the Seller's Disclosure Letter, the rates for
         services collected pursuant to such rate authorizations are not being
         collected subject to refund. In addition, sales for resale of natural
         gas in interstate commerce made by the Company or its subsidiaries of
         natural gas that is produced from reserves owned by a party other than
         such seller are made pursuant to Section 311 and the applicable
         Regulations thereunder or the terms and conditions of a blanket sales
         certificate authorization issued by the FERC under the NGA, as such
         authorization may be amended, modified or interpreted from time to time
         pursuant to Orders of the FERC or of any Court. Intrastate
         transportation, exchange, storage, gathering, and pipeline sales
         services performed by the Company and its subsidiaries may be subject
         to certain facilities construction, rate, reporting and prior
         authorization requirements applicable under the Laws of the States of
         Texas, Oklahoma, and Louisiana, and Regulations promulgated thereunder
         by the TRC, the OCC and the LCC, respectively, as such Regulations may
         be amended, modified and interpreted by the respective Governmental
         Authorities or the Courts.

                  (b) To the Knowledge of the Seller, the Company and its
         subsidiaries have obtained all Permits, including all certificates of
         public convenience and necessity and rate authorizations required by
         the LCC and by the FERC, as are necessary to carry on their businesses
         as currently conducted, except for any such Permits that the failure to
         possess

                                      -10-

         which, individually or in the aggregate, could not reasonably be
         expected to have a Material Adverse Effect on the Company. Such Permits
         are in full force and effect, have not been violated in any respect
         that could reasonably be expected to have a Material Adverse Effect on
         the Company and, to the Knowledge of the Seller, no suspension,
         revocation or cancellation thereof has been threatened.

                  (c) Neither the Company nor any subsidiary of the Company is
         subject to the jurisdiction of the FERC under the NGA, except pursuant
         to Sections 284.121 through 284.126 of the FERC's regulations, 18
         C.F.R. ss.ss.284.121 through 284.126 (1995), Section 284.142 of the
         FERC's regulations, 18 C.F.R., ss. 284.142 (1995), and pursuant to a
         limited jurisdiction blanket certificate issued under Section 284.227
         of the FERC's regulations, 18 C.F.R. ss.284.227 (1994). The Company and
         its subsidiaries have engaged in no activities which would subject
         them, their activities, or their facilities to the NGA jurisdiction of
         the FERC. All of the Company's and its subsidiaries' facilities used to
         transport natural gas are non-jurisdictional intrastate transmission or
         "gathering" facilities within the meaning of the NGA and/or NGPA, and,
         except as set forth in the first sentence of this Section 4.08(c),
         neither the Company nor any of its subsidiaries has or is engaged in
         the interstate transmission of gas through any of its facilities. The
         Company's and each of its subsidiaries' representations concerning the
         jurisdictional status of its facilities and operations made to natural
         gas purchasers and interstate or intrastate pipelines in order to
         effect sales or to facilitate transportation transactions (whether for
         the Company, its subsidiaries or any third parties) have been and,
         through the Closing, are true and correct in all Material respects, and
         the Company and its subsidiaries have complied in all Material respects
         with the terms and conditions of such sales, transportation or
         interconnect or similar arrangements (including "on behalf of"
         certificates). Neither the Company nor any of its subsidiaries has
         violated, and neither has received notification from any Governmental
         Authority that it has violated, the NGA, the NGPA, or any other Law
         concerning the transmission and sale of natural gas or the conduct of
         gathering, treating, processing, and compression activities associated
         with natural gas, except for any violations that, individually or in
         the aggregate, could not reasonably be expected to have a Material
         Adverse Effect on the Company.

         Section 4.09. LITIGATION; COMPLIANCE WITH LAWS. There are no actions,
suits, investigations or proceedings (including any proceedings in arbitration)
pending or, to the Knowledge of the Seller, threatened against the Company or
any of its subsidiaries, at law or in equity, in any Court or before or by any
Governmental Authority (excluding any rulemaking or similar proceedings of
general applicability and any appeal or petition for review related thereto),
except actions, suits or proceedings that (a) are set forth in Section 4.09 or
Section 4.12 of the Seller's Disclosure Letter or (b), individually or, with
respect to multiple actions, suits or proceedings that allege similar theories
of recovery based on similar facts, in the aggregate, could not reasonably be
expected to have a Material Adverse Effect on the Company. Except as set forth
in Section 4.09 of the Seller's Disclosure Letter, the Company and its
subsidiaries are in substantial compliance with all applicable Laws and
Regulations and are not in default with respect to any Order applicable to the
Company or any of its subsidiaries, except such events of noncompliance or
defaults that, individually or in the aggregate, could not reasonably be
expected to have a Material Adverse Effect on the Company.

                                      -11-

         Section 4.10.     TAXES.

                  (a) Except for such matters as could not reasonably be
         expected to have a Material Adverse Effect on the Company, (i) all
         returns and reports of or with respect to any Tax which are required to
         be filed by or with respect to the Company or any of its subsidiaries
         ("Tax Returns") on or before the Closing Date have been or will be

         Returns on or before the Closing Date have been or will be timely paid
         in full, (iii) all withholding Tax requirements imposed on or with

         satisfied in full in all respects and (iv) no penalty, interest or
         other charge is or will become due with respect to the late filing of
         any such Tax Return or late payment of any such Tax.

                  (b) Except as set forth in Section 4.10(b) of the Seller's
         Disclosure Letter, all Tax Returns have been audited by the applicable
         Governmental Authority or the applicable statute of limitations has
         expired for the period covered by such Tax Returns.

                  (c) Except as set forth in Section 4.10(c) of the Seller's
         Disclosure Letter, there is not in force any extension of time with
         respect to the due date for the filing of any Tax Return or any waiver
         or agreement for any extension of time for the assessment or payment of
         any Tax due with respect to the period covered by any Tax Return.

         promptly to the Purchaser and the Purchaser's Representatives such
         information concerning the business, properties, contracts, records and
         personnel of the Company and its subsidiaries (including financial,
         operating and other data and information) as may be reasonably
         requested, from time to time, by the Purchaser.

                                      -20-

                  (b) Notwithstanding the foregoing provisions of this Section,
         the Seller shall not be required to cause the Company or any of its
         subsidiaries to grant access or furnish information to the Purchaser or
         any of the Purchaser's Representatives to the extent that such
         information is subject to an attorney/client or attorney work product
         privilege or that such access or the furnishing of such information is
         prohibited by Law or by a valid and binding confidentiality agreement
         with a third party; PROVIDED, HOWEVER, that, in the latter instance, if
         so requested by the Purchaser, the Seller will use all commercially
         reasonable efforts to obtain from such third party a waiver of such
         prohibition.

                  (c) The information received pursuant to this Section shall be
         deemed to be "Evaluation Material" for purposes of the Confidentiality
         Agreement.

         Section 6.04.     APPROPRIATE ACTION; CONSENTS; FILINGS.

                  (a) The Seller and the Purchaser shall each use, and shall
         cause each of their respective subsidiaries to use, all commercially
         reasonable efforts (i) to take, or to cause to be taken, all
         appropriate action, and to do, or to cause to be done, all things
         necessary, proper or advisable under applicable Law or otherwise to
         consummate and make effective the transactions contemplated by this
         Agreement, (ii) to obtain from any Governmental Authorities any
         Licenses, Permits or Orders required to be obtained by the Purchaser or
         the Seller or any of their subsidiaries in connection with the
         authorization, execution and delivery of this Agreement and the
         performance of their obligations hereunder, (iii) to make all necessary
         filings, and thereafter to make promptly any other required
         submissions, with respect to this Agreement required under (A) the HSR
         Act or (B) any other applicable Law, Regulation or Order; PROVIDED,
         HOWEVER, that the Purchaser and the Seller shall cooperate with each
         other in connection with the making of all such filings and in
         supplying any information requested supplementally or by second request
         from any Governmental Authority. The Purchaser and the Seller shall
         request early termination of the waiting period under the HSR Act with
         respect to the transactions contemplated hereby.

                  (b) The Purchaser and the Seller agree to cooperate and to
         cause their respective subsidiaries to cooperate with respect to, and
         agree to use all commercially reasonable efforts vigorously to contest
         and resist and to have vacated, lifted, reversed or overturned, any
         action, including legislative, administrative or judicial action,
         including any Order (whether temporary, preliminary or permanent) of
         any Governmental Authority, that is in effect and that restricts,
         prevents or prohibits the consummation of the transactions contemplated
         by this Agreement. Each of the Purchaser and the Seller also agree to
         take any and all commercially reasonable actions that may be required
         by any Governmental Authority as a condition to the granting of any
         Permit or Order required in order to permit the consummation of the
         transactions contemplated hereby or as may be required to vacate, lift,
         reverse or overturn any administrative or judicial action that would
         otherwise cause any condition to the Closing not to be satisfied;
         PROVIDED, HOWEVER, that in no event shall the Seller take any action
         that could reasonably be expected to have a Material Adverse Effect on
         the Company and in no event shall either party be required to take any
         action that could reasonably be expected to have a Material Adverse
         Effect on such party or to result in a breach of this Agreement.


                                      -21-

                  (c) Each of the Seller and the Purchaser shall use, and shall
         cause its subsidiaries to use, all commercially reasonable efforts to
         obtain from all Persons (other than Governmental Authorities) all
         consents that are (i) necessary, proper or advisable or (ii) otherwise
         required under any contracts, licenses, leases, Easements, or other
         agreements to which the Seller or the Purchaser or any of its
         subsidiaries is a party or by which it is bound, in order to permit the
         Seller or the Purchaser, as the case may be, to perform its obligations
         hereunder.

                  (d) If any party shall fail to obtain any third party consent
         described in subsection (c) of this Section, such party shall use all
         commercially reasonable efforts, and shall take any such actions
         reasonably requested by the other party, to limit the adverse effect
         upon the Seller and the Purchaser, their respective subsidiaries, and
         their respective businesses resulting, or which could reasonably be
         expected to result after the Closing, from the failure to obtain such
         consent.

                  (e) Each of the Purchaser and the Seller shall promptly notify
         the other of (i) any complaints, investigations or hearings (or
         communications indicating that the same may be contemplated) from or by
         any Governmental Authorities with respect to the transactions
         contemplated hereby or (ii) the institution or the threat of litigation
         involving this Agreement or the transactions contemplated hereby.

         Section 6.05. PENDING AND UPCOMING RATE PROCEEDINGS. The Company and
its subsidiaries currently have pending rate proceedings in FERC Docket Nos.
PR96-2 (Traditional System), PR96-7 (Anadarko System) and TRC Docket No. 8457
with respect to transportation service under Section 311. From the execution of
this Agreement by the Seller until the Closing, the Seller shall cause the
Company and its subsidiaries to use all commercially reasonable efforts to
obtain approval for the maximum rates requested in such proceedings and to
prevail in such litigation. Notwithstanding the foregoing, the Seller reserves
the right to permit the Company and its subsidiaries to agree with the
appropriate Governmental Authorities or other parties, at any time prior to the
Closing, to settle all or any part of the issues in such proceedings or
litigation, including any issues regarding the appropriate maximum rate, fuel
component, rate of return or other cost of service or rate design aspect, when
in the sole judgment of the Company or such subsidiary, such action is in the
best interests of the Company or such subsidiary and could not reasonably be
expected to have a Material Adverse Effect on the Company.

         Section 6.06.     PREPARATION AND FILING OF TAX RETURNS; PAYMENT OF 
TAXES.

                  (a) With respect to each Tax Return covering a taxable period
         ending on or before the Closing Date that is required to be filed after
         the Closing Date for, by or with respect to the Company or any
         subsidiary of the Company (other than the Tax Returns described in
         subsection (c) of this Section), the Seller shall cause such Tax Return
         to be prepared, shall cause to be included in such Tax Return all items
         of income, gain, loss, deduction and credit or other items
         (collectively "Tax Items") required to be included therein, and shall
         deliver the original of such Tax Return to the Purchaser at least
         thirty (30) days prior to the due date (including extensions) of such
         Tax Return. If the amount of the Tax shown to be due on such Tax Return
         exceeds the amount of the Closing Date Tax Accrual for such Tax, the
         Seller shall

                                      -22-

         pay to the Purchaser the amount of such excess not less than five (5)
         days prior to the due date of such Tax Return. If the amount of the Tax
         shown to be due on such Tax Return is less than the amount of the
         Closing Date Tax Accrual for such Tax, the Purchaser shall pay to the
         Seller the amount of such difference not less than five (5) days prior
         to the due date of such Tax Return. The Purchaser shall cause the
         Company or the respective subsidiary to file timely such Tax Return
         with the appropriate taxing authority and to pay the amount of Taxes
         shown to be due on such Tax Return.

                  (b) With respect to each Tax Return covering a taxable period
         beginning on or before the Closing Date and ending after the Closing
         Date that is required to be filed after the Closing Date for, by or
         with respect to the Company or any subsidiary of the Company (other
         than the Tax Returns described in subsection (c) of this Section), the
         Purchaser shall cause such Tax Return to be prepared and shall cause to
         be included in such Tax Return all Tax Items required to be included
         therein. The Purchaser shall determine, subject to verification by the
         Seller, the portion, if any, of the Tax due with respect to the period
         covered by such Tax Return which is attributable to the Company or the
         respective subsidiary for a PreClosing Taxable Period. The
         determination of the portion of such Tax that is attributable to the
         Pre-Closing Period shall be based, in the case of real and personal
         property Taxes, on a per diem basis and, in the case of other Taxes, on
         the actual activities, taxable income or taxable loss of the Company
         and its subsidiaries during the Pre-Closing Period and PostClosing
         Period. At least thirty (30) days prior to the due date (including
         extensions) of such Tax Return, the Purchaser shall deliver to the
         Seller a copy of such Tax Return. If the amount of Tax attributable to
         the Pre-Closing Taxable Period exceeds the amount of the Closing Date
         Tax Accrual for such Tax, the Seller shall pay to the Purchaser the
         amount of such excess Tax not less than five (5) days prior to the due
         date of such Tax Return. If the amount of Tax attributable to the
         Pre-Closing Taxable Period is less than the amount of the Closing Date
         Tax Accrual for such Tax, the Purchaser shall pay to the Seller the
         amount of such difference not less than five (5) days prior to the due
         date of such Tax Return. The Purchaser shall cause the Company or the
         respective subsidiary to file timely such Tax Return with the
         appropriate taxing authority and to pay timely the amount of Taxes
         shown to be due on such Tax Return. For purposes of this subsection,
         (i) any Texas franchise Tax imposed on the Taxable Earned Surplus of
         the Company or any of its subsidiaries which is determined with
         reference to the federal taxable income of the Company or any of its
         subsidiaries for the period up to and including the Closing Date shall
         be treated as attributable to a Pre-Closing Taxable Period, and (ii)
         any state income or franchise Tax (other than Texas franchise Tax)
         which is imposed on the Company or any of its subsidiaries in a
         Post-Closing Taxable Period and is determined by reference to federal
         taxable income of a Pre-Closing Taxable Period of the Company or any of
         its subsidiaries shall be treated as attributable to a Pre-Closing
         Taxable Period.

                  (c) The Seller shall cause to be included in the consolidated
         federal income Tax Returns (and the state income Tax Returns of any
         state in which the Seller files consolidated, combined or unitary
         income Tax Returns) of the Seller's Group for all periods ending on or
         before or which include the Closing Date, all Tax Items of the Company
         and its subsidiaries which are required to be included therein, shall
         file timely all such Tax Returns with the appropriate taxing
         authorities and shall pay timely all Taxes due with respect to the
         periods covered by such Tax Returns.

                                      -23-

                  (d) The Seller shall be responsible for the payment of all
         state and local transfer, sales, use or other similar taxes resulting
         from the transactions contemplated by this Agreement.

                  (e) From time to time prior to the Closing Date, the Seller
         shall have the right to cause the Company or any of its subsidiaries to
         pay to the IRS or the applicable state taxing authority (or to the
         Seller or another member of the Seller's Group as agent for the payment
         of such Tax) such amounts on account of the Company's and the
         subsidiaries' shares of consolidated federal income Tax liability and
         any consolidated, combined or unitary state income Tax liability of the
         Seller's Group for the 1996 taxable year as are consistent with any tax
         sharing agreements, arrangements, policies or guidelines ("Tax Sharing
         Agreements") that may exist between the Company or any subsidiary of
         the Company, on the one hand, and the Seller or any other Affiliate of
         the Seller, on the other. All such Tax Sharing Agreements will be
         terminated and any obligations to make payments under them shall be
         canceled as of the Closing Date. Any and all payments then remaining
         due under those Tax Sharing Agreements shall be made prior to their
         termination.

         Section 6.07.     ACCESS TO INFORMATION.  From and after the Closing:

                  (a) The Seller and each member of the Seller's Group shall
         grant to the Purchaser (or its designees) access at all reasonable
         times to all of the information, books and records relating to the
         Company and its subsidiaries within the possession of the Seller or any
         member of the Seller's Group (including work papers and correspondence
         with taxing authorities), and shall afford to the Purchaser (or its
         designees) the right (at the Purchaser's expense) to take extracts
         therefrom and to make copies thereof, to the extent reasonably
         necessary to permit the Purchaser or any of its Affiliates (or its
         designees) to prepare Tax Returns, to conduct negotiations with Tax
         authorities, to fulfill an obligation to any Governmental Authority
         imposed by Law, Regulation or Order and to implement the provisions of,
         or to investigate or defend any claims between the parties arising
         under, this Agreement.

                  (b) The Purchaser shall grant or cause the Company and its
         subsidiaries to grant to the Seller or any of its Affiliates (or its
         designees) access at all reasonable times to all of the information,
         books and records relating to the Company and its subsidiaries within
         the possession of the Purchaser, the Company or its subsidiaries
         (including work papers and correspondence with taxing authorities), and
         shall afford to the Seller (or its designees) the right (at the
         Seller's expense) to take extracts therefrom and to make copies
         thereof, to the extent reasonably necessary to permit the Seller (or
         its designees) to prepare Tax Returns, to conduct negotiations with Tax
         authorities, to fulfill an obligation to any Governmental Authority
         imposed by Law, Regulation or Order and to implement the provisions of,
         or to investigate or defend any claims between the parties arising
         under, this Agreement or otherwise.

                  (c) Each of the parties hereto will preserve and retain all
         schedules, work papers and other documents relating to any Tax Returns
         of or with respect to the Company or any of its subsidiaries or to any
         claims, audits or other proceedings affecting the Company or any of its
         subsidiaries until the expiration of the statute of limitations
         (including extensions)

                                      -24-

         applicable to the taxable period to which such documents relate or
         until the final determination of any controversy with respect to such
         taxable period, and until the final determination of any payments that
         may be required with respect to such taxable period under this
         Agreement.

                  (d) Notwithstanding the foregoing provisions of this Section,
         neither party hereto shall be required to grant or cause to be granted
         to the other access to information, books and records or to furnish
         extracts or copies thereof if such information, books and records also
         include information regarding such party or any of its Affiliates. In
         such circumstances, such party shall either (i) provide appropriately
         detailed summaries of the information contained therein or (ii), in
         providing extracts or copies thereof, redact the information relating
         to such party or its Affiliates.

         Section 6.08.     EMPLOYEES AND EMPLOYEE BENEFIT PLANS.

                  (a) Effective as of the Closing, the Seller shall cause the
         Company to withdraw as a participating employer from all Benefit Plans
         other than any Benefit Plans as to which the Company is the sole
         sponsoring entity.

                  (b) Effective as of the Closing, the Seller shall cause each
         employee of the Company on the Closing Date (the "Continuing
         Employees") who is a participant in the Central and South West System
         Pension Plan (the "CSW Pension Plan") on the Closing Date to become
         100% vested in his accrued benefit under the CSW Pension Plan as of the
         Closing and shall cause the accrued benefits of the Continuing
         Employees under the CSW Pension Plan to be distributed to such
         Continuing Employees pursuant to the terms and provisions of the CSW
         Pension Plan as if the Continuing Employees had terminated employment
         for purposes of the CSW Pension Plan as of the Closing. Effective as of
         the Closing, the Purchaser shall take all action necessary and
         appropriate to extend coverage under a new or existing defined benefit
         pension plan (the "Purchaser's Pension Plan") qualified under section
         401(a) of the Code to the Continuing Employees who were participants in
         the CSW Pension Plan at the Closing. The Continuing Employees shall be
         credited with service under the Purchaser's Pension Plan, for
         eligibility, vesting, and accrual of benefit purposes, with the service
         credited to them for such purposes under the CSW Pension Plan as of the
         Closing. The Continuing Employees' benefits under the Purchaser's
         Pension Plan shall be reduced by the actuarial equivalent of the
         pension benefit paid or payable to such Continuing Employees from the
         CSW Pension Plan. In making such reduction, the pension paid or payable
         under each plan shall be determined under the provisions of each plan
         as if payable at normal retirement date in the normal form; PROVIDED,
         HOWEVER, that the pension benefit paid or payable under the CSW Pension
         Plan in the normal form at the normal retirement date shall be
         converted to the normal form under the Purchaser's Pension Plan using
         the actuarial assumptions under the Purchaser's Pension Plan. The net
         pension payable under the Purchaser's Pension Plan shall then be
         actuarially adjusted in accordance with the provisions of the
         Purchaser's Pension Plan for the actual time and form of payment.

                  (c) Effective as of the Closing, the Purchaser shall take all
         action necessary and appropriate to extend coverage under a new or
         existing defined contribution plan (the "Purchaser's Savings Plan")
         qualified under section 401(a) of the Code to the Continuing

                                      -25-

         Employees who have account balances under the Central and South West
         System Thrift Plus Plan (the "CSW Thrift Plan") at the Closing. The
         Continuing Employees shall be credited with service under the
         Purchaser's Savings Plan, for eligibility and vesting purposes, with
         the service credited to them under the terms of the CSW Thrift Plan as
         of the Closing. As soon as practicable following the Closing, the
         Seller shall cause to be transferred from the trustee of the CSW Thrift
         Plan to the trustee of the Purchaser's Savings Plan an amount in cash
         or in kind (with any in kind transfers to be agreed upon by the Seller
         and the Purchaser, except that it is hereby agreed that participant
         loans shall be transferred in kind; PROVIDED, HOWEVER, that any loan
         repayments shall be applied to investments available under the
         Purchaser's Savings Plan) equal to the aggregate account balances (both
         vested and unvested) of the Continuing Employees under the CSW Thrift
         Plan determined as of the transfer date (which shall be a valuation
         date) in accordance with the methods of valuation set forth in the CSW
         Thrift Plan. From and after the date of such transfer, the Purchaser
         shall cause the Purchaser's Savings Plan to assume the obligations of
         the CSW Thrift Plan with respect to the benefits accrued by the
         Continuing Employees under the CSW Thrift Plan, and the CSW Thrift Plan
         shall cease to be responsible therefor.

                  (d) Except as provided in subsections (e), (f), and (j) of
         this Section, claims for benefits under welfare plans, as such term is
         defined in Section 3(1) of ERISA, in which Continuing Employees
         participate arising out of occurrences prior to the Closing shall be
         covered by the applicable welfare plan of the Seller in accordance with
         the terms of such plan. All such claims for benefits by Continuing
         Employees arising out of occurrences subsequent to the Closing shall be
         covered by the applicable welfare plan of the Purchaser in accordance
         with the terms of such plan. Neither the Purchaser nor any of its
         subsidiaries shall be liable for payment of any disability benefit due
         to disabled employees of the Company or its subsidiaries or Continuing
         Employees who, prior to the Closing, are in the waiting or qualifying
         period for disability benefits. After the Closing, the Seller shall be
         responsible for disability benefits payable to such persons under the
         Seller's disability plan.

                  (e) Claims for medical, dental, prescription drug, vision, and
         employee assistance plan benefits by Continuing Employees with respect
         to purchases or services or treatment rendered prior to the Closing
         shall be covered by the applicable welfare plan of the Seller in
         accordance with the terms of such plan. Claims for such benefits by
         Continuing Employees with respect to purchases or services or treatment
         rendered on or subsequent to the Closing shall be covered by the
         applicable welfare plan of the Purchaser in accordance with the terms
         of such plan. The Purchaser shall cause the Continuing Employees to be
         granted credit under the welfare plan of the Purchaser providing
         medical, dental, prescription drug, vision, and employee assistance
         plan coverage, for the year during which the Closing occurs, for any
         deductibles already incurred by such Continuing Employees for such year
         under the welfare plan of the Seller providing such coverage, and the
         Purchaser shall cause to be waived any eligibility waiting periods and
         pre-existing condition restrictions under the welfare plans of the
         Purchaser to the extent necessary to provide immediate coverage under
         such welfare plans as of the Closing (but only to the extent that
         coverage was provided under the applicable welfare plan of the Seller).
         The Purchaser shall provide the Continuing Employees (and their
         respective beneficiaries) with medical benefits sufficient to satisfy
         the obligations of the Seller under Section 4980B(f) of the Code with
         respect to such Continuing Employees so that the Seller will not incur
         any tax under Section 4980B of the Code.

                                      -26-

                  (f) Effective as of the Closing, the Purchaser shall, or shall
         cause the Company to, take all action necessary and appropriate to
         extend coverage under a new or existing health care spending account
         plan (the "Purchaser's Health Care Plan") to the Continuing Employees.
         A Continuing Employee shall be considered to have an account balance
         under the Purchaser's Health Care Plan following the Closing that is
         the same as such Continuing Employee's account balance under the
         Central and South West System Health Care Reimbursement Plan (the "CSW
         Health Care Plan") immediately prior to the Closing, and the elections
         in effect for the year in which the Closing Date occurs under the CSW
         Health Care Plan shall remain in effect under the Purchaser's Health
         Care Plan for the remainder of such year unless changed as a result of
         a change in family status. As of the Closing, the positive and negative
         balances of the Continuing Employees under the CSW Health Care Plan
         shall be netted. To the extent that there is a net positive balance,
         claims under the Purchaser's Health Care Plan following the Closing
         shall be paid from the Central and Southwest System Voluntary
         Employees' Beneficiary Association (the "CSW VEBA") until such balance
         is eliminated. Thereafter, all such claims shall be paid by the
         Company. To the extent that there is a net negative balance as of the
         Closing, the Company shall make a contribution to the CSW VEBA as of or
         before the Closing equal to the net negative balance. For purposes of
         this paragraph, a Continuing Employee shall be considered to have a
         positive balance in such employee's account as of the Closing if the
         amounts that have been withheld from such Continuing Employee's
         compensation during the year in which the Closing occurs, pursuant to
         the CSW Health Care Plan, prior to the Closing, exceeded disbursements
         on such Continuing Employee's behalf from the CSW Health Care Plan
         prior to the Closing for such year's claims. A Continuing Employee
         shall be considered to have a negative balance in such Continuing
         Employee's account as of the Closing if the disbursements on such
         Continuing Employee's behalf from the CSW Health Care Plan prior to the
         Closing for the year in which the Closing occurs exceeds the amounts
         that have been withheld from such Continuing Employee's compensation
         during such year, pursuant to the CSW Health Care Plan, prior to the
         Closing.

                  (g) Effective as of the Closing, the Purchaser shall, or shall
         cause the Company to, take all action necessary and appropriate to
         extend coverage under a new or existing dependent care spending account
         plan (the "Purchaser's Dependent Care Plan") to the Continuing
         Employees. A Continuing Employee shall be considered to have an account
         balance under the Purchaser's Dependent Care Plan following the Closing
         that is the same as such Continuing Employee's account balance under
         the Central and South West System Dependent Care Assistance Plan (the
         "CSW Dependent Care Plan") immediately prior to the Closing, and the
         elections in effect for the year in which the Closing Date occurs under
         the CSW Dependent Care Plan shall remain in effect under the
         Purchaser's Dependent Care Plan for the remainder of such year unless
         changed as a result of a change in family status. To the extent that
         there are amounts held in the CSW VEBA as of the Closing attributable
         to a Continuing Employee's participation in the CSW Dependent Care
         Plan, claims under the Purchaser's Dependent Care Plan following the
         Closing shall be paid from the CSW VEBA until such amounts are
         depleted. Thereafter, all such claims shall be paid by the Company.

                  (h) For a period of one year following the Closing Date, the
         Purchaser shall, or shall cause the Company to, establish and manage a
         severance benefit plan to cover the Continuing Employees with such
         severance benefit being a severance benefit plan

                                      -27-

         substantially similar to the Central and South West System Severance
         Benefit Plan, effective July 1, 1995 (the "CSW Severance Benefit
         Plan"). For purposes of such plan, (i) any restructuring,
         reorganization, or other position elimination involving a Continuing
         Employee shall be considered approved within the meaning of Section 2.1
         of the CSW Severance Benefit Plan and (ii) service with the Seller or
         any of its subsidiaries, including the Company, shall be taken into
         account.

                  (i) Vacation entitlement accrued by Continuing Employees for
         the year in which the Closing Date occurs under the Company's vacation
         policy as in effect as of the Closing shall be recognized by the
         Purchaser and the Company following the Closing. Service with the
         Seller or any of its subsidiaries, including the Company, shall be
         taken into account for purposes of the Purchaser's vacation policy
         following the Closing.

                  (j) With respect to all employees who retired from employment
         with the Company prior to the Closing and who have been, or are
         eligible to be, provided with post-retirement medical, dental, or life
         insurance coverage as of the Closing under plans sponsored by the
         Seller or the Company, the Seller shall assume or retain any and all
         liability with respect to the provision of such coverages to such
         retired employees and their eligible dependents on and after the
         Closing. With respect to all Continuing Employees who retire from
         employment with the Company after the Closing and who have been, or are
         eligible to be, provided with post-retirement medical, dental or life
         insurance as of the Closing under plans sponsored by the Company or the
         Seller, the Purchaser shall assume any and all liability with respect
         to the provision of such coverages to such retired Continuing Employees
         and their eligible dependents on and after the Closing (up to a present
         benefit obligation of $3.2 million, computed using the actuarial
         assumptions of the CSW Pension Plan).

                  (k) Claims for workers compensation benefits for Continuing
         Employees arising out of occurrences prior to the Closing shall be the
         responsibility of the Seller. Claims for workers compensation benefits
         for Continuing Employees arising out of occurrences subsequent to the
         Closing shall be the responsibility of the Purchaser.

                  (l) Nothing herein shall be deemed or construed (i) to give
         rise to any rights, claims, benefits, or causes of action to any
         Continuing Employee or any other Person, except the Seller or (ii) to
         prevent, restrict, or limit the Purchaser or the Company and its
         subsidiaries following the Closing from modifying or terminating its
         pension or other benefit plans, programs, or policies from time to time
         as it may deem appropriate, subject only to compliance with the express
         provisions of subsections (a) through (k) of this Section for the
         benefit of the Seller.

         Section 6.09. WORKING CAPITAL CONTRIBUTION. Effective as of the
Closing, the Seller shall cause (a) the purchase agreement dated January 2,
1991, between the Company and CSW Credit, Inc. pursuant to which the Company
factors its trade accounts receivable to CSW Credit, Inc. to be amended to
terminate the factoring of accounts receivable of the Company arising after the
Closing, (b) the Company's intercompany payable or receivable balance, as the
case may be, in the CSW Money Pool to be forgiven in full resulting in a capital
contribution (or resulting in a distribution), and (c) to be assigned (without
recourse) to the Company, as a capital contribution, the right, title and

                                      -28-

interest in and to the amount of current accounts receivable balances existing
as of the Closing that are required to bring the Working Capital of the Company
as of the Closing to zero (after giving effect to clause (b) of this Section and
Section 6.10(a)) and that have been factored by the Company to CSW Credit, Inc.
pursuant to such purchase agreement.

         Section 6.10. INTERCOMPANY ACCOUNTS; POST-CLOSING RELATIONSHIPS;
         CLOSING COVENANTS.

                  (a) Except for the Company's intercompany payable or
         receivable balance, as the case may be, in the CSW Money Pool (which is
         specifically addressed in Section 6.09), and except for those accounts
         set forth in Section 6.10(a) of the Seller's Disclosure Letter, the
         Seller, effective as of the Closing, will cause all intercompany
         accounts (including those pertaining to all income taxes) between the
         Company and its subsidiaries, on the one hand, and the Seller and its
         Affiliates (other than the Company and its subsidiaries), on the other,
         to be paid or otherwise satisfied.

                  (b) Effective as of the Closing, the only obligations of the
         Company and its subsidiaries to the Seller and its Affiliates (other
         than the Company and its subsidiaries) and of the Seller and its
         Affiliates (other than the Company and its subsidiaries) to the Company
         and its subsidiaries shall be those obligations expressly set forth in
         the contracts listed in Section 6.10(b) of the Seller's Disclosure
         Letter, irrespective of any prior relationships, arrangements, business
         practices or courses of dealing and any forecasts, estimates or
         projections related to the subject matter of such contracts.

                  (c) The Seller agrees to assign to the Company, at or prior to
         the Closing, the confidentiality agreements with all other prospective
         purchasers of the Company.

                  (d) At the Purchaser's request, the Seller agrees to provide
         the transition services described in Annex B to this Agreement to the
         Company until April 15, 1997 at a level sufficient to effect a smooth
         transfer of the ownership and operation of the Company by the Seller to
         the Purchaser, and the Purchaser agrees to pay the Seller the cost of
         such services (consistent with the payment for similar services made in
         the past under that certain agreement among Central and South West
         Services, Inc., the Company and certain Affiliates of the Company dated
         August 18, 1988).

                  (e) As of the Closing, the Seller shall cause the Company and
         its subsidiaries to have no outstanding long term indebtedness for
         borrowed money which would be required to be reflected under GAAP in
         the consolidated financial statements of the Company as of the Closing,
         other than any such indebtedness reflected in the Consolidated
         Financial Statements and the debt secured by the real estate mortgages
         disclosed in Section 4.07(a) of the Seller's Disclosure Letter.

                  (f) The Seller agrees to use commercially reasonable efforts
         to cooperate with the Company and its subsidiaries after the Closing in
         making and prosecuting claims under insurance policies and programs of
         the Seller and its Affiliates that cover the Company and its
         subsidiaries. The insurance trust of which the Seller is a member under
         the Trust Agreement dated November 1, 1990 (the "Trust"), will continue
         to process, respond to,

                                      -29-

         defend, and pay claims received prior to the Closing. The Company and
         its subsidiaries will process, respond to, defend, and pay claims made
         after the Closing; PROVIDED, HOWEVER, that the Company and its
         subsidiaries after the Closing will continue to be entitled to make
         claims against insurance policies purchased by the Trust prior to the
         Closing in which the Company and its subsidiaries are named as insureds
         in accordance with the terms of such policies so long as such insurance
         policies remain in effect, but the Company and its subsidiaries will
         not make claims against the Trust or Trust assets for claims made after
         the Closing. The Seller shall cause no premiums or assessments to be
         due and payable from the Company and its subsidiaries to the Trust (and
         no distributions or refunds to be due and payable from the Trust to the
         Company and its subsidiaries) after the Closing.

                  (g) Prior to or at the Closing the Seller shall enter into, or
         cause Public Service Company of Oklahoma to enter into, an agreement
         providing for the indemnity to the Company and its subsidiaries
         described in the seventh paragraph of Note 10 to the Consolidated
         Financial Statements as such indemnity relates to the claims against
         the Company or such subsidiaries described in such paragraph or similar
         claims against the Company or such subsidiaries made subsequent to
         December 31, 1995 that relate to events occurring or circumstances
         existing prior to the Closing. Such agreement shall contain terms
         similar to those set forth in Sections 8.02(e) and (f) regarding the
         defense and settlement of claims, but in any event shall be in form and
         substance reasonably acceptable to the Purchaser.

         Section 6.11. ESTIMATED PURCHASE PRICE. At least three (3) days prior
to the Closing, the Seller in good faith shall prepare in reasonable detail and
deliver to the Purchaser a statement setting forth the Seller's calculations
with respect to its best estimation of the Purchase Price, including its best
estimation of the amount of Working Capital of the Company as of the Closing
(the "Estimated Purchase Price").

         Section 6.12. DETERMINATION OF FINAL PURCHASE PRICE. As soon as
reasonably practicable and in any event within sixty (60) days following the
Closing Date, the Purchaser shall cause the Company to prepare and deliver to
the Seller a statement setting forth the Purchaser's calculation (the "Final
Purchase Price Calculation") of the final purchase price (the "Final Purchase
Price"), including the actual amount of Working Capital of the Company as of the
Closing and, if the Final Purchase Price differs from the Estimated Purchase
Price, the reasons therefor in reasonable detail. The Final Purchase Price
Calculation shall contain sufficient detail to enable the Seller to relate the
calculations contained therein to the books and records of the Company and its
subsidiaries. The Purchaser shall cause the Company to make available to the
Seller all information in the possession of the Company and its subsidiaries
reasonably required for the Seller to verify whether the Final Purchase Price
Calculation is correct. Within forty-five (45) days following the delivery of
the Final Purchase Price Calculation, the Seller shall notify the Purchaser
whether it agrees with the Final Purchase Price Calculation; PROVIDED, HOWEVER,
that, if the Seller shall fail so to notify the Purchaser within such forty-five
(45) day period, it shall be deemed to have agreed with the Final Purchase Price
Calculation. If the Seller shall disagree with the Final Purchase Price
Calculation, the Seller and the Purchaser shall endeavor in good faith to agree
on the Final Purchase Price but, if they shall not agree within thirty (30) days
following the Seller's notice to the Purchaser, either the Purchaser or the
Seller may cause the issues in dispute to be referred for resolution to Price
Waterhouse L.L.P. (or such other firm of independent public accountants as the
Purchaser and the Seller may mutually designate),

                                      -30-

and the Seller and the Purchaser shall cooperate, and the Purchaser shall cause
the Company and its subsidiaries to cooperate, with such firm of independent
public accountants by making available to that firm such information, books and
records and such personnel as such firm may reasonably request. The costs of
such firm of independent public accountants shall be borne equally by the
Purchaser and the Seller. The Purchaser and the Seller shall use all
commercially reasonable efforts to cause such firm of independent public
accountants to examine the books and records of the Company and its
subsidiaries, as well as any other information that such firm may reasonably
conclude is necessary to make such determination, and to make a determination
with respect to such issues within sixty (60) days following the date such
issues are referred to them. Any such determination shall be final and binding
on the Purchaser and the Seller and may be enforced by appropriate judicial or
other proceedings. The Final Purchase Price shall then be calculated by the
Seller and the Purchaser based on those matters as to which they are in
agreement and the determination by the independent public accountants as to
those matters, if any, as to which they did not agree. If the Final Purchase
Price as so determined (whether by agreement of the parties or determination by
accountants) shall exceed the Estimated Purchase Price, the Purchaser shall pay
the Seller the amount of such excess plus interest thereon from the Closing Date
until paid at a rate equal to the base or reference rate quoted from time to
time by the Bank, but, if the Final Purchase Price as so determined shall be
less than the Estimated Purchase Price, the Seller shall pay the Purchaser the
amount of such shortfall plus interest thereon from the Closing Date until paid
at a rate equal to the base or reference rate quoted from time to time by the
Bank, such payment in either case to be made within five (5) days following the
final determination of the Final Purchase Price.

         Section 6.13. PUBLIC ANNOUNCEMENTS. Except as otherwise required by Law
or the New York Stock Exchange, the Seller and the Purchaser shall consult with
each other before issuing any press release or otherwise making any public
statements with respect to this Agreement and the transactions contemplated
hereby and shall not issue any such press release or make any such public
statement prior to such consultation. The press release announcing the execution
and delivery of this Agreement shall be a joint press release of the Seller and
the Purchaser.

         Section 6.14. CONFIDENTIALITY. After the Closing, the Seller will not,
and will not permit its Affiliates which it controls (excluding the Company and
its subsidiaries) to, disclose or provide to any other Person any material
non-public information of a confidential nature concerning the business or
operations of the Company or its subsidiaries, except as required by Law,
Regulation or Order.

         Section 6.15. ACQUISITION PROPOSALS. From the execution of this
Agreement by the Seller until the Closing or the termination of this Agreement
in accordance with its terms, the Seller will not, and will cause its officers,
directors, employees or agents not to, directly or indirectly, (a) take any
action to solicit, initiate or encourage any proposal regarding the acquisition
of the Company or its assets by merger or otherwise or (b), except as required
by Law, Regulation or Order, engage in negotiations with, or disclose any
non-public information relating to the Company, or afford access to its
properties, books or records to any Person that has made or, to the Knowledge of
the Seller, may be considering making an acquisition proposal.

         contemplated hereby to occur at the Closing shall have been made or
         obtained (other than any requirement the nonfulfillment of which and
         any Permit or Order the nonreceipt of which could not reasonably be
         expected to have a Material Adverse Effect on the Seller, the Purchaser
         or the Company); and

                  (b) No temporary restraining order, preliminary or permanent

         extent such representations and warranties speak as of an earlier date)
         as of the Closing as though made at and as of the Closing and the
         Purchaser shall have received a certificate signed on behalf of the
         Seller by the president or any vice president and by the chief
         financial officer of the Seller to such effect (except the

         4.09 insofar as they relate to the Palo Duro Pipeline);

                  (b) The Seller shall have performed in all material respects
         all obligations required to be performed by it under this Agreement at
         or prior to the Closing Date, and the Purchaser shall have received a

         of Directors of the Seller authorizing the execution, delivery and

         executed and delivered by the Seller at the Closing;

                                      -32-

                  (d) There shall not be any action or proceeding pending or
         threatened (including any investigation) by any Governmental Authority
         to restrain, enjoin or invalidate the transactions contemplated herein
         or to compel the Purchaser to divest any material assets, which would,
         in the judgment of the Board of Directors of the Purchaser, made in
         good faith and based upon the advice of counsel, involve expense or
         lapse of time or result in a reconfiguration of the Purchaser's
         business which expense, lapse of time or result would be materially
         adverse to the interests of the Purchaser;

                  (e) The Purchaser shall have received from counsel to the
         Seller an opinion dated as of the Closing Date in form and substance

         Section 7.03. CONDITIONS TO OBLIGATION OF THE SELLER. The obligation of
the Seller to effect the transactions contemplated hereby to occur at the
Closing shall be subject to the satisfaction or, to the extent permitted by Law,
waiver of each of the following conditions:

         forth in this Agreement shall be true and correct in all material
         respects as of the execution of this Agreement by the Purchaser and
         (except to the extent such representations and warranties speak as of
         an earlier date) as of the Closing as though made at and as of the
         Closing and the Seller shall have received a certificate signed on
         behalf of the Purchaser by the president or any vice president and by
         the chief financial officer of the Purchaser to such effect;

                  (b) The Purchaser shall have performed in all material
         respects all obligations required to be performed by it under this
         Agreement at or prior to the Closing Date, and the Seller shall have

         president or any vice president and by the chief financial officer of
         the Purchaser to such effect;

         in the judgment of the Board of Directors of the Seller, made in good
         faith and based upon the advice of counsel, involve expense or lapse of
         time or result in a reconfiguration of the Seller's business which
         expense, lapse of time or result would be materially adverse to the
         interests of the Seller or (ii) pay over any material amount of the
         proceeds from the Merger;

                  (e) The Seller shall have received from counsel to the

                                  ARTICLE VIII.

                                 INDEMNIFICATION

         Section 8.01. SURVIVAL OF REPRESENTATIONS, WARRANTIES, COVENANTS AND
AGREEMENTS. The representations, warranties, covenants and agreements of the
parties contained in Articles II, III, IV, V and VI (other than the
representations and warranties contained in Sections 3.02, 3.06, 4.02(a),
4.08(c) (to the extent the representations and warranties set forth in such
Section relate to the Palo Duro Pipeline), 4.09, 4.10, 4.11, 4.12, 4.16, 4.17
and 4.18 and the covenants and agreements contained in Sections 6.06, 6.07,
6.08, 6.10 and 6.14) shall survive both the Closing and any investigation by the
parties with respect thereto but shall terminate and be of no further force or
effect on the first anniversary of the Closing. The representations and
warranties contained in Sections 4.09 and 4.11 shall survive both the Closing
and any investigation by the parties with respect thereto but shall terminate
and be of no further force and effect on the second anniversary of the Closing.
The representations and warranties contained in Section 4.12 shall survive the
Closing and any investigation by the parties with respect thereto until the
tenth anniversary of the Closing. The representations and warranties contained
in Sections 3.02, 3.06, 4.02(a), 4.08(c) (except to the extent the
representations and warranties set forth in such Section relate to the Palo Duro
Pipeline), 4.16, 4.17 and 4.18 and the covenants and agreements contained in
Sections 6.06, 6.07, 6.08, 6.10(a)-(f) and 6.14 shall survive both the Closing
and any investigation by the parties with respect thereto until the expiration
of the statute of limitations (including any and all periods of extension or
tolling thereof) applicable to actions on written contracts. The representations
and warranties contained in Sections 4.08(c) (to the extent the representations
and warranties set forth in such Section relate to the Palo Duro Pipeline), and
4.10 and the covenants contained in Section 6.10(g) shall survive both the
Closing and any investigation by the parties with respect thereto until the
expiration of the statute of limitations (including any and all periods of
extension or tolling thereof) applicable to the subject matter of such sections.
Notwithstanding the foregoing, any such representation, warranty, covenant or
agreement as to which a bona fide claim relating thereto is asserted in writing
in accordance with Section 8.02 during such survival period shall, with respect
only to such claim, survive such survival period. The covenants and agreements
in this Article VIII shall survive the Closing and shall remain in full force
and effect for such period as is necessary to resolve any bona fide claim made
with respect to any representation, warranty, covenant or agreement contained in
this Agreement during the survival period thereof. The remaining covenants and
agreements of the parties hereto contained in this Agreement shall survive the
Closing without any contractual limitation on the period of survival.

         Section 8.02.     GENERAL INDEMNIFICATION.

                  (a) Subject to the limitations on survival contained in
         Section 8.01, if the transactions contemplated hereby to occur at the
         Closing are effected, each party hereto (the "Indemnifying Party")
         hereby agrees, from and after the Closing, to indemnify and hold
         harmless the other party hereto (the "Indemnified Party") against any
         losses, claims, damages

                                      -34-

         or liabilities ("Losses") which such Indemnified Party shall actually
         incur, to the extent that such Losses (or actions, suits or proceedings
         in respect thereof and any appeals therefrom ("Proceedings")) (other
         than any Losses subject to Section 8.03 herein):

                           (i) arise out of or are based upon any allegation
                  that any representation or warranty made herein in Article
                  III, IV or V for the benefit of the Indemnified Party by the
                  Indemnifying Party is untrue or has been breached in any
                  respect; or

                           (ii) arise out of or are based upon any allegation
                  that any covenant or agreement made herein for the benefit of
                  the Indemnified Party by the Indemnifying Party has not been
                  performed in accordance with its terms;

         and will reimburse the Indemnified Party for any legal or other
         expenses reasonably incurred by it in connection with investigating or
         defending against any such Losses or Proceedings. Notwithstanding the
         foregoing, except for Losses resulting from breaches of Sections 3.02,
         3.06, 4.02, 4.08(c) (to the extent the representations and warranties
         set forth in such Section relate to the Palo Duro Pipeline), 4.10,
         4.18, 4.19, 5.08, 6.06, 6.09, 6.10 and 6.12, the Indemnifying Party
         shall (x) not be liable to the Indemnified Party under this Section for
         any Loss incurred by the Indemnified Party which does not exceed
         $500,000, and (y) be liable to the Indemnified Party under this Section
         only for the amount of Losses incurred by the Indemnified Party which
         exceed $10,000,000 in the aggregate; PROVIDED, HOWEVER, that the amount
         of such Losses that are subject to indemnification hereunder shall not
         exceed the Final Purchase Price; and PROVIDED, FURTHER, that the Losses
         incurred by an Indemnified Party shall, for purposes of determining the
         threshold level thereof in accordance with this sentence and otherwise,
         be offset by (i) the amount of any such Losses incurred by the
         Indemnifying Party jointly and severally with the Indemnified Party to
         the extent of payments made by the Indemnifying Party; and (ii) the
         proceeds of any insurance received by the Indemnified Party with
         respect thereto.

                  (b) Promptly after receipt by the Indemnified Party under
         subsection (a) of this Section of notice of a Loss or the commencement
         of any Proceeding against which it believes it is indemnified under
         this Section, the Indemnified Party shall, if a claim in respect
         thereto is to be made against the Indemnifying Party under this
         Section, notify the Indemnifying Party in writing of the commencement
         THEREOF; PROVIDED, HOWEVER, that the omission so to notify the
         Indemnifying Party shall not relieve it from any liability which it may
         have to the Indemnified Party to the extent that the Indemnifying Party
         is not prejudiced by such omission.

                  (c) For purposes of determining whether an event, fact or
         occurrence constitutes a misrepresentation or a breach of any
         representation, warranty, covenant or agreement contained in this
         Agreement for which indemnification can be or is sought under this
         Section, as used in any such representation, warranty, covenant or
         agreement, the terms "Material" and "Material Adverse Effect" shall
         have the following meanings:

                           "Material" shall mean material to the condition
                  (financial and other), results of operations or business of a
                  specified Person and its

                                      -35-

                  subsidiaries, if any, taken as whole; PROVIDED that, without
                  limiting the foregoing definition, the parties acknowledge and
                  agree that any amount exceeding $500,000 is material; and

                           "Material Adverse Effect" shall mean any change or
                  effect that would be materially adverse to the consolidated
                  business, condition (financial or otherwise), operations,
                  performance or properties of a specified Person and its
                  subsidiaries, if any, taken as a whole; PROVIDED that, without
                  limiting the foregoing definition, the parties acknowledge and
                  agree that any amount exceeding $5,000,000 is material in
                  respect of Section 4.05 and that any amount exceeding $500,000
                  is material in all other cases;

         PROVIDED that the special purpose use of the terms "Material" and
         "Material Adverse Effect" in this subsection (c) shall be disregarded
         and given no effect in determining what is "material" for purposes of
         the definitions of such terms contained in Annex A to this Agreement
         and how they are used elsewhere in this Agreement.

                  (d) The Indemnifying Party shall, within thirty (30) days
         after receipt of a notice of Loss or Proceeding given pursuant to
         subsection (b) of this Section, either (i) acknowledge liability, as
         between the Indemnifying Party and the Indemnified Party, for such Loss
         or the amount in controversy in such Proceeding and pay the Indemnified
         Party the amount of such Loss or the amount in controversy in such
         Proceeding in cash or other immediately available funds (or establish
         by agreement with the Indemnified Party an alternative payment
         schedule), (ii) acknowledge liability, as between the Indemnifying
         Party and the Indemnified Party, for such Loss or the amount in
         controversy in such Proceeding, disavow the validity of the Loss or
         Proceeding or the amount thereof and, to the extent that it shall so
         desire in accordance with subsection (d) of this Section, assume the
         legal defense thereof, or (iii) object (or reserve the right to object
         until additional information is obtained) to the claim for
         indemnification or the amount thereof, setting forth the grounds
         therefor in reasonable detail; PROVIDED that, if the Indemnifying Party
         objects (or reserves its right to object) within such 30-day period as
         provided in this clause (iii), then the Indemnified Party may bring
         suit (in the same Proceeding or otherwise) to resolve the dispute and,
         pending final resolution of such dispute, the Indemnified Party may
         proceed as though the Indemnifying Party had responded in accordance
         with clause (i) above. If the Indemnifying Party does not respond to
         the Indemnified Party as provided in this subsection within such 30-day
         period, the Indemnifying Party shall be deemed to have acknowledged its
         liability for such indemnification claim in accordance with clause (i)
         of this subsection and the Indemnified Party may exercise any and all
         of its rights under applicable law to collect such amount.

                  (e) If any such Proceeding shall be brought against an
         Indemnified Party and it shall notify the Indemnifying Party thereof in
         accordance with subsection (c) of this Section, the Indemnifying Party
         shall, if it shall have responded to such notice in accordance with
         clause (ii) of subsection (c) of this Section, be entitled to assume
         the legal defense thereof with counsel reasonably satisfactory to the
         Indemnified Party. After notice from the Indemnifying Party to the
         Indemnified Party of its election to assume the defense of such

                                      -36-

         claim or such action, the Indemnifying Party shall not be liable to the
         Indemnified Party under this Section for any attorney's fees or other
         expenses (except reasonable costs of investigation) subsequently
         incurred by the Indemnified Party in connection with the defense
         thereof. If the Indemnifying Party does not assume the defense of a
         Proceeding as to which it has acknowledged liability, as between itself
         and the Indemnified Party, pursuant to clause (ii) of subsection (c) of
         this Section, the Indemnified Party may require the Indemnifying Party
         to reimburse it on a current basis for its reasonable expenses of
         investigation, reasonable attorney's fees and expenses and reasonable
         out-of-pocket expenses incurred in the defense thereof and, subject to
         the provisions of subsection (e) of this Section, the Indemnifying
         Party shall be bound by the result obtained with respect thereto by the
         Indemnified Party.

                  (f) An Indemnifying Party will not, without the prior written
         consent of the Indemnified Party (which consent shall not be
         unreasonably withheld), settle or compromise or consent to the entry of
         any judgment with respect to any pending or threatened Proceeding in
         respect of which indemnification or contribution may be sought
         hereunder (whether or not the Indemnified Party is an actual or
         potential party to such Proceeding) unless such settlement, compromise
         or consent includes an unconditional release of the Indemnified Party
         from all liability arising out of such Proceeding. If the Indemnifying
         Party has responded to the Indemnified Party pursuant to clause (i) of
         subsection (c) of this Section, the Indemnified Party may settle or
         compromise or consent to the entry of any judgment with respect to the
         Proceeding that was the subject of notice to the Indemnifying Party
         pursuant to subsection (c) of this Section without the consent of the
         Indemnifying Party. An Indemnified Party will not otherwise, without
         the prior written consent of the Indemnifying Party (which consent
         shall not be unreasonably withheld), settle or compromise or consent to
         the entry of any judgment with respect to any pending or threatened
         Proceeding, but, if such Proceeding is settled or compromised or if
         there is entered any judgment with respect to any such Proceeding, in
         either case with the consent of the Indemnifying Party, or if there be
         a final judgment of the plaintiff in any such Proceeding, the
         Indemnifying Party agrees to indemnify and hold harmless any
         Indemnified Party from and against any loss or liability by reason of
         such settlement, compromise or judgment.

                  (g) From and after the Closing, except as provided in Section
         8.03, the provisions of this Section shall be the sole and exclusive
         remedy of each party hereto for any breach of the other party's
         representations, warranties, covenants or agreements contained in this
         Agreement; PROVIDED, HOWEVER, that each party may seek specific
         performance by the other party of the agreements and obligations set
         forth in Sections 6.07, 6.13 and 6.14. NOTWITHSTANDING ANYTHING IN THIS
         AGREEMENT TO THE CONTRARY, IN NO EVENT SHALL ANY LOSSES, CLAIMS,
         DAMAGES OR LIABILITIES INDEMNIFIED HEREUNDER INCLUDE ANY CONSEQUENTIAL
         OR PUNITIVE DAMAGES, EXCEPT TO THE EXTENT THAT SUCH ARE AWARDED TO A
         THIRD PARTY IN A PROCEEDING AGAINST AN INDEMNIFIED PARTY.

                                      -37-

         Section 8.03.     TAX INDEMNIFICATION AND AUDITS.

                  (a) From and after the Closing, the Seller hereby agrees to
         protect, defend, indemnify and hold harmless the Purchaser and the
         Company and its subsidiaries from and against, and agrees to pay, all:

                           (i) Taxes of the Company or any subsidiary of the
                  Company attributable to any Pre-Closing Taxable Period (except
                  for Taxes arising out of any transaction of the Company or its
                  subsidiaries not in the ordinary course of business occurring
                  on the Closing Date but subsequent to the Closing), but only
                  to the extent the amount of such Taxes exceeds the amount
                  taken into account as a liability for such Taxes in
                  determining the Purchase Price;

                           (ii) Taxes of any corporation (other than the Company
                  and its subsidiaries) that is or was a member of the Seller's
                  Group; and

                           (iii) Taxes of the Company or any subsidiary of the
                  Company attributable to the Section 338(h)(10) Elections made
                  pursuant to Section 8.04.

                  (b) From and after the Closing, the Purchaser agrees to
         protect, defend, indemnify and hold harmless the Seller from and
         against, and agrees to pay, all:

                           (i) Taxes of the Company or any subsidiary of the
                  Company attributable to any Post-Closing Taxable Period; and

                           (ii) Taxes arising out of any transaction of the
                  Company or its subsidiaries not in the ordinary course of
                  business occurring on the Closing Date and after the Closing.

                  (c) If a claim shall be made by any taxing authority that, if
         successful, would result in the indemnification of a party (the "Tax
         Indemnified Party") under this Section, the Tax Indemnified Party shall
         promptly notify the party (the "Tax Indemnifying Party") obligated
         under this Section to indemnify the Tax Indemnified Party in writing of
         such fact; provided, however, that the omission to so notify the
         Indemnifying Party shall not relieve it from any liability which it may
         have to the Indemnified Party to the extent that the Indemnifying Party
         is not prejudiced by such omission.

                           (i) The Tax Indemnified Party shall take such action
                  in connection with contesting such claim as the Tax
                  Indemnifying Party shall request in writing from time to time,
                  including the selection of counsel and experts and the
                  execution of powers of attorney; PROVIDED that (A) within
                  thirty (30) days after the notice required by this subsection
                  has been delivered (or such earlier date that any payment of
                  Taxes is due by the Tax Indemnified Party but in no event
                  sooner than five (5) days after the Tax Indemnifying Party's
                  receipt of such notice), the Tax Indemnifying Party requests
                  that such claim be contested, and (B) the Tax Indemnifying
                  Party shall have agreed to pay to the Tax Indemnified Party
                  all costs and expenses that the Tax Indemnified Party

                                      -38-

                  incurs in connection with contesting such claim, including
                  reasonable attorneys' and accountants' fees and disbursements.
                  The Tax Indemnified Party shall not make any payment of such
                  claim for at least thirty (30) days (or such shorter period as
                  may be required by applicable law) after the giving of the
                  notice required by this subsection, shall give to the Tax
                  Indemnifying Party any information requested relating to such
                  claim, and otherwise shall cooperate with the Tax Indemnifying
                  Party in order to contest effectively any such claim. The Tax
                  Indemnifying Party shall determine the method of any contest
                  of such claim and shall control the conduct thereof.

                           (ii) Subject to the provisions of paragraph (i) of
                  this subsection, the Tax Indemnified Party shall enter into a
                  settlement of such contest with the applicable taxing
                  authority or prosecute such contest to a determination in a
                  Court, all as the Tax Indemnifying Party may request.

                           (iii) Promptly after the extent of the liability of
                  the Tax Indemnified Party with respect to a claim shall be
                  established by the final judgment or decree of a Court or a
                  final and binding settlement with a Governmental Authority
                  having jurisdiction thereof, the Tax Indemnifying Party shall
                  pay to the Tax Indemnified Party the amount of any Taxes to
                  which the Tax Indemnified Party may become entitled by reason
                  of the provisions of this Section.

                  (d) Notwithstanding anything to the contrary in this Section,
         any interest, penalties, fines, assessments or additions to Tax
         resulting from or attributable to the failure of the Tax Indemnified
         Party to act in a timely manner, including in filing Tax Returns,
         responding to Tax audit or other inquiries or making payments shall not
         be indemnifiable hereunder and shall be the sole responsibility of the
         Tax Indemnified Party.

                  (e) In addition to the provisions of this subsection (c) of
         this Section, if any proposed audit adjustments of a Pre-Closing
         Taxable Period Tax Return could result in a tax adjustment for a
         Post-Closing Taxable Period, the Seller shall promptly inform the
         Purchaser. If the Seller elects not to contest the adjustment, the
         Purchaser shall have the option, at the Purchaser's own expense, to
         contest the proposed adjustment in accordance with the provisions of
         subsection (c) of this Section.

                  (f) In addition to the provisions of subsection (c) of this
         Section, if any proposed audit adjustments of a Post-Closing Taxable
         Period Tax Return could result in an audit adjustment for a Pre-Closing
         Taxable Period, the Purchaser shall promptly inform the Seller. If the
         Purchaser elects not to contest the adjustment, the Seller shall have
         the option, at the Seller's own expense, to contest the proposed
         adjustment in accordance with the provisions of subsection (c) of this
         Section.

                  (g) Except for the indemnification provided in Section 8.02
         for breach of any representation or warranty contained in Section 4.10
         or any covenant or agreement contained in Section 6.06, the
         indemnification provided in this Section shall be the sole remedy for
         any claim in respect of Taxes. In the event of a conflict between the
         provisions of this Section and any other provisions of this Agreement,
         the provisions of this Section shall control. The

                                      -39-

         limitations of Section 8.02 shall not apply to any amounts for which a
         party is liable under this Section. Any claim for indemnity under this
         Section must be made prior to the expiration of the applicable Tax
         statute of limitations with respect to the relevant taxable period
         (including all periods of tolling or extension).

                  (h) To the extent any determination of Taxes, whether as the
         result of an audit or examination, a claim for refund, the filing of an
         amended return or otherwise results in a refund of Taxes paid (a
         "Refund"), (i) the Seller shall be entitled to any part of such Refund
         attributable to a Pre-Closing Taxable Period, (ii) the Purchaser shall
         be entitled to any part of such Refund attributable to a Post-Closing
         Taxable Period, and (iii) the Purchaser and the Seller shall each be
         entitled to a Refund attributable to a taxable period described in
         Section 6.06(b) in the portions that the Purchaser and the Seller
         originally bore any Taxes payable with respect to such taxable period.
         Whichever party receives such Refund shall, within ten (10) days after
         receipt thereof, pay such Refund, or any part thereof, and the interest
         received thereon to the party entitled thereto under this subsection.

                  (i) Any payment from the Purchaser to the Seller pursuant to
         Section 6.06 or this Section shall be treated for Tax purposes as an
         increase in the Purchase Price, and any payment from the Seller to the
         Purchaser pursuant to Section 6.06 or this Section shall be treated for
         Tax purposes as a reduction in the Purchase Price.

         Section 8.04.     SECTION 338(H)(10) ELECTIONS.

                  (a) The Seller, as the common parent of the Seller's Group,
         and the Purchaser shall make a joint election under section 338(h)(10)
         of the Code and a similar election under any applicable state income
         tax law for the Company and for each of the corporate subsidiaries
         (collectively, the "Section 338(h)(10) Elections"). At the Closing, the
         Seller shall deliver to the Purchaser an Internal Revenue Service Form
         8023-A and any similar form under applicable state income tax law (the
         "Forms") with respect to the Section 338(h)(10) Elections, which shall
         have been duly executed by an authorized person for the Seller. The
         Purchaser shall cause the Forms to be duly executed by an authorized
         person for the Purchaser, shall complete any schedules required to be
         attached thereto, shall provide a copy of the executed Forms and
         schedules to the Seller, and the Seller and the Purchaser shall duly
         and timely file the Forms as prescribed by Treasury Regulation ss.
         1.338(h)(10)-1 or the corresponding provisions of applicable state
         income tax law.

                  (b) The Purchaser shall select a firm of qualified appraisers
         to conduct an appraisal of the Company's assets (the "Appraisal"),
         which selection must be approved by the Seller, such approval not to be
         unreasonably withheld. The Seller and the Purchaser agree that the
         results of the Appraisal shall be used to allocate the Purchase Price
         and liabilities of the Company and its subsidiaries (plus other
         relevant items) to the assets of the Company and its subsidiaries for
         all purposes (including United States or any state, county or local
         government Tax purposes) in accordance with the Code and applicable
         Treasury Regulations. Such allocation of the Purchase Price shall be
         prepared by the Purchaser and submitted in writing to the Seller within
         ninety (90) calendar days after the date on which the Final Purchase
         Price is determined. The Seller shall consent to such Purchase Price
         allocation unless such

                                      -40-

         Purchase Price allocation is unreasonable. If the Seller does not
         object in writing to such proposed allocation within thirty (30)
         calendar days after receipt of the Purchaser's written proposal, the
         Purchaser's proposed allocation shall become final and binding on the
         Seller and the Purchaser. If the Seller makes timely objection to the
         Purchaser's proposal, the Purchaser and Seller shall have thirty (30)
         calendar days to reach agreement or the allocation shall be submitted
         to Price Waterhouse L.L.P. The determination of Price Waterhouse L.L.P.
         shall be final and binding on the Purchaser and the Seller and the fees
         and expenses of Price Waterhouse L.L.P. shall be borne equally by the
         Purchaser and the Seller. Price Waterhouse L.L.P. shall adjust the
         Purchase Price allocation provided by the Purchaser to the extent
         necessary to make such allocation reasonable. The Purchaser and the
         Seller shall duly prepare and timely file such reports and information
         returns as may be required under the Code and applicable Treasury
         Regulations and any corresponding or comparable provisions of
         applicable state and local Tax laws to report the allocation of the
         Purchase Price.

                  (a) by mutual consent of the Seller and the Purchaser;

         any representation, warranty, covenant or agreement on the part of the
         Seller set forth in this Agreement, or if any representation or
         warranty of the Seller shall have become untrue in any material
         respect, in either case such that the conditions set forth in Section
         7.02(a) or Section 7.02(b), as the case may be, would be incapable of
         being satisfied by June 30, 1996 (or as otherwise extended as described
         in Section 9.01(e)); PROVIDED, HOWEVER, that, in any case, a willful
         breach shall be deemed to cause such conditions to be incapable of
         being satisfied for purposes of this subsection;

                  (c) by the Seller, upon a breach in any material respect of
         any representation, warranty, covenant or agreement on the part of the

         warranty of the Purchaser shall have become untrue in any material
         respect, in either case such that the conditions set forth in Section
         7.03(a) or Section 7.03(b), as the case may be, would be incapable of
         being satisfied by June 30, 1996 (or as otherwise extended as described
         in Section 9.01(e)); PROVIDED, HOWEVER, that, in any case, a willful

         being satisfied for purposes of this subsection (c);

                  (d) by either the Seller or the Purchaser, if there shall be
         any Order which is final and nonappealable preventing the consummation
         of the transactions contemplated hereby, unless the party relying on
         such Order to terminate this Agreement has not complied with its
         obligations under Section 6.04(b); and

                                      -41-

                  (e) by either the Seller or the Purchaser, if the Closing
         shall not have occurred prior to June 30, 1996; PROVIDED, HOWEVER, that
         this Agreement may be extended by written notice from either party
         hereto to the other to a date not later than July 31, 1996, if the
         Closing shall not have occurred as a direct result of the
         nonfulfillment of the condition contained in subsection (a) of Section

         The right of any party hereto to terminate this Agreement pursuant to
this Section shall remain operative and in full force and effect regardless of
any investigation made by or on behalf of any party hereto, any person
controlling any such party or any of their respective officers, directors,
employees or representatives, whether prior to or after the execution of this
Agreement; PROVIDED, HOWEVER, that each party shall provide written notice to
the other party of any breach by such other party of a representation, warranty,
covenant or agreement set forth in this Agreement as soon as practicable upon
learning of such breach, and the non-breaching party may only terminate this
Agreement pursuant to subsections (b) or (c) of this Section, as the case may
be, if such breach is not cured within ten (10) days of such notice being given.
If such ten (10) day cure period extends beyond the date set forth in such
subsections, then such date shall be extended to be the first business day
immediately following the expiration of such ten (10) day cure period.

         Section 9.02. EFFECT OF TERMINATION; NONCONSUMMATION. Except as
provided in this Section and Section 9.03, in the event of the termination of
this Agreement pursuant to Section 9.01, this Agreement shall forthwith become
void and of no further force and effect. If the transactions contemplated hereby
are not consummated by reason of the termination of this Agreement or otherwise,
there shall be no liability on the part of either party hereto to the other and
all rights and obligations of each party hereto shall cease, except that nothing
herein (other than the immediately following sentence) shall relieve any party
of any liability for (a) any breach of such party's covenants or agreements
contained in this Agreement or (b) any breach of such party's representations or
warranties contained in this Agreement. NOTWITHSTANDING ANYTHING IN THIS
AGREEMENT TO THE CONTRARY, IN NO EVENT SHALL ANY LOSSES, CLAIMS, DAMAGES OR
LIABILITIES CLAIMED WITH RESPECT TO THE EXCEPTION TO THE IMMEDIATELY PRECEDING
SENTENCE INCLUDE ANY CONSEQUENTIAL OR PUNITIVE DAMAGES, EXCEPT TO THE EXTENT
THAT SUCH ARE AWARDED TO A THIRD PARTY IN A PROCEEDING AGAINST AN INDEMNIFIED

respectively, pursuant to Section 251 of the DGCL."

                                        1

         2.       Section 2.05(c) of the Merger Agreement is amended to read, in

                  "The bylaws of the Company shall be the bylaws of the

         4.       Section 6.06(d) of the Merger Agreement is amended to read, in
its entirety, as follows:

                  "Except as provided in Section 6.16(e), the Seller shall be

         5.       Section 6.08(a) of the Merger Agreement is amended to read, in
its entirety, as follows:

                  "Effective as of the Closing, the Seller shall cause the
         Company to withdraw as a participating employer from all Benefit Plans
         other than any Benefit Plans as to which the Company is the sole
         sponsoring entity. The preceding sentence notwithstanding, the Company
         shall continue to participate in the CSW System Employees' Cafeteria
         Plan with respect to employee contributions for the medical, dental,
         prescription drug, vision, and employee assistance plan coverage
         provided to Continuing Employees (as such term is defined in subsection
         (b) of this Section) by Seller welfare plans following the Closing
         pursuant to the provisions of subsection (e) of this Section."

         6.       Section 6.08(c) of the Merger Agreement is amended to read, in
its entirety, as follows:

                  "Effective as of the Closing, the Seller shall cause each
         Continuing Employee who is a participant in the Central and South West
         System Thrift Plan (the "CSW Thrift Plan") on the Closing Date to
         become 100% vested in his account balances under the CSW Thrift Plan as
         of the Closing Date and shall cause the account balances of the
         Continuing Employees under the CSW Thrift Plan to be distributable to
         such Continuing Employees pursuant to the terms and provisions of the
         CSW Thrift Plan in accordance with the provisions of Code ss.ss.
         401(k)(2)(B)(i)(II) and 401(k)(10). Effective as of the Closing, the
         Purchaser shall take all action necessary and appropriate to extend
         coverage under a new or existing defined contribution plan (the
         "Purchaser's Savings Plan") qualified under section 401(a) of the Code
         to the

                                        2

         Continuing Employees. The Continuing Employees shall be credited with
         service under the Purchaser's Savings Plan, for eligibility and vesting
         purposes, with the service credited to them under the terms of the CSW
         Thrift Plan as of the Closing. The Purchaser's Savings Plan shall
         accept direct rollovers (as that term is defined in temporary Treasury
         regulation ss. 1.401(a)(31)-1T, Q&A-3) from the CSW Thrift Plan of
         account balances of Continuing Employees, including direct rollovers of
         participant loans in kind."

         7.       Section 6.08(e) of the Merger Agreement is amended to read, in
its entirety, as follows:

                  "Claims for medical, dental, prescription drug, vision, and
         employee assistance plan benefits by Continuing Employees with respect
         to purchases or services or treatment rendered prior to the Closing
         shall be covered by the applicable welfare plan of the Seller in
         accordance with the terms of such plan. Claims for such benefits by
         Continuing Employees with respect to purchases or services or treatment
         rendered on or subsequent to the Closing shall be covered by the
         applicable welfare plan of the Purchaser in accordance with the terms
         of such plan. The Purchaser shall cause the Continuing Employees to be
         granted credit under the welfare plan of the Purchaser providing
         medical, dental, prescription drug, vision, and employee assistance
         plan coverage, for the year during which the Closing occurs, for any
         deductibles already incurred by such Continuing Employees for such year
         under the welfare plan of the Seller providing such coverage, and the
         Purchaser shall cause to be waived any eligibility waiting periods and
         pre-existing condition restrictions under the welfare plans of the
         Purchaser to the extent necessary to provide immediate coverage under
         such welfare plans as of the Closing (but only to the extent that
         coverage was provided under the applicable welfare plan of the Seller).
         The Purchaser shall provide the Continuing Employees (and their
         respective beneficiaries) with medical benefits sufficient to satisfy
         the obligations of the Seller under Section 4980B(f) of the Code with
         respect to such Continuing Employees so that the Seller will not incur
         any tax under Section 4980B of the Code. The preceding provisions of
         this subsection (e) to the contrary notwithstanding, Continuing
         Employees shall be provided medical, dental, prescription drug, vision,
         and employee assistance plan benefits under the applicable Seller
         welfare plan for a period of ninety (90) days following the Closing (or
         such shorter period as the Seller and the Purchaser may agree) on the
         same basis as they were receiving such benefits immediately prior to
         the Closing. Such coverage shall be provided to the Continuing
         Employees at the same employee contribution rate as in effect on the
         Closing Date. The Purchaser shall reimburse the Seller for the cost of
         such coverage (determined at the maximum rate that may be charged for
         COBRA coverage pursuant to section 4980B(f)(2)(C) of the Code) less the
         contributions of the Continuing Employees."


                                        3

         8.       Section 6.08(j) of the Merger Agreement is amended to read, in
its entirety, as follows:

                  "With respect to all employees who retired from employment
         with the Company prior to the Closing and who have been, or are
         eligible to be, provided with post-retirement medical, dental, or life
         insurance coverage as of the Closing under plans sponsored by the
         Seller or the Company, the Seller shall assume or retain any and all
         liability with respect to the provision of such coverages to such
         retired employees and their eligible dependents on and after the
         Closing. With respect to all Continuing Employees who retire from
         employment with the Company or the Purchaser after the Closing and who
         would be eligible (without regard to any changes in the terms of such
         eligibility made after May 9, 1996) to receive post-retirement medical,
         dental, or life insurance benefits under plans sponsored by the Company
         or the Seller were they to retire on the day preceding the Closing, the
         Seller shall provide post-retirement medical, dental, and life
         insurance coverage to such retired Continuing Employees and their
         eligible dependents under plans sponsored by the Seller following such
         Continuing Employees' retirement from employment with the Company or
         the Purchaser, and the Purchaser shall reimburse the Seller on an
         annual basis for the actual medical and dental benefit payments under
         such coverage (excluding any payments reimbursed by stop loss insurance
         coverage) up to a maximum aggregate reimbursement of $3.2 million."

         9.       Section 6.09(c) of the Merger Agreement is amended to read, in
its entirety, as follows:

                  "the Company to acquire from CSW Credit, Inc., in
consideration of funds contributed to the Company by the Seller for such
purpose, the right, title and interest in and to the amount of current accounts
receivable balances existing as of the Closing that are required to bring the
Working Capital of the Company to zero (after giving effect to clause (b) of
this Section and Section 6.10(a)) and that have been factored by the Company to
CSW Credit, Inc. pursuant to such purchase agreement."

         10.      The last sentence of Section 6.10(f) of the Merger Agreement 
is deleted and replaced, in its entirety, by the following:

                  "If after the Closing, the Company receives from the Trust
payment of any amount pursuant to Section 11.3 of the Trust Agreement, the
Purchaser shall pay to the Seller such amount. If after the Closing the Company
must pay to the Trust any amount pursuant to the Trust Agreement, the Seller
shall pay to the Purchaser such amount."

         11.      The words "sixty (60) days" contained in the first sentence of
Section 6.12 of the Merger Agreement are changed to read "ninety (90) days."


                                        4

         12.      A new Section 6.16 of the Merger Agreement is added that 
reads, in its entirety, as follows:

                  "SALE OF GAS PROCESSING PLANTS; RELEASE; INDEMNITY.

         (a) The Seller shall use commercially reasonable efforts to cause
Transok Gas Processing Company, a wholly-owned subsidiary of the Company, to
sell (the "Processing Plants Sale") all of its right, title and interest in and
to the Processing Plants to CIBC, Inc. pursuant to that certain Bill of Sale
(the "Bill of Sale") dated the Closing Date. The Purchaser has informed the
Seller that the Purchaser or one or more subsidiaries or affiliates thereof may
lease (the "Processing Plants Lease") the Processing Plants from CIBC, Inc. The
Seller and the Purchaser hereby agree that the Estimated Purchase Price, the
Final Purchase Price and the Working Capital of the Company shall be computed as
though the Processing Plants Sale and the Processing Plants Lease, if any, and
the receipt of cash in consideration thereof had not occurred.

         (b) Notwithstanding any other provision of this Agreement to the
contrary, none of the Processing Plants Sale, the Seller's failure to own the
Processing Plants as of the Closing because of the Processing Plants Sale or the
Processing Plants Lease, if any, shall cause (i) any representation or warranty
made in this Agreement by the Seller to be untrue, incorrect or breached by the
Seller in any respect, (ii) any covenant or agreement made in this Agreement by
the Seller to be unfulfilled or otherwise breached by the Seller in any respect,
or (iii) any condition to the obligation of the Purchaser to effect the
transactions contemplated by the Agreement to not be satisfied; PROVIDED,
HOWEVER, that those representations and warranties of the Seller contained in
Article IV of this Agreement shall be true and correct in all material respects
with respect to the Processing Plants as of the time immediately prior to
consummation of the Processing Plants Sale, and such representations and
warranties shall continue to be subject to the indemnification obligations set
forth in Section 8.02(a).

         (c) The Purchaser (on behalf of itself and any subsidiary or affiliate
thereof) hereby irrevocably releases and discharges the Seller from any and all
liabilities, obligations, debts, controversies, causes of action, suits,
covenants, contracts, agreements, judgments, demands or claims of any kind
(known or unknown)(collectively referred to herein as "Liabilities"), whether
arising under contract, tort, implied or express warranty, strict liability,
common law, statute or otherwise, against the Seller and the Seller's
stockholders, directors, officers, employees, agents and affiliates
(collectively, the "CSW Released Parties"), and whether arising directly or
indirectly through the Company, Transok Gas Processing Company or any other
person, INCLUDING THOSE ARISING FROM THE JOINT, CONCURRENT OR COMPARATIVE
NEGLIGENCE OF ANY CSW RELEASED PARTY, which the Purchaser or any subsidiary or
affiliate thereof ever had, now has, or hereafter can or may have in any way
arising out of, based upon or related to the Processing Plant's Sale or the
Processing Plants Lease, if any, or the Bill of Sale, and any documents
effecting the Processing Plants Lease (the "Processing Plants Transaction
Documents"), unless such Liabilities would have arisen or been incurred if the
Processing Plants Sale, the Processing Plants Lease, if any, or any Processing
Plants Transaction Documents had not

                                        5

been entered into and the Merger had occurred with the Processing Plants still
being owned by Transok Gas Processing Company.

         (d) The Purchaser (on behalf of itself and any subsidiary or affiliate
thereof) hereby waives any rights it or any subsidiary or affiliate thereof may
have to initiate judicial or other proceedings against the CSW Released Parties
for any claim based on the failure of any party, including the CSW Released
Parties, to perform or observe any of the provisions contained in the Processing
Plants Transaction Documents, unless such rights would have arisen or been
incurred if the Processing Plants Sale, the Processing Plants Lease, if any, or
any Processing Plants Transaction Documents had not been entered into and the
Merger had occurred with the Processing Plants still being owned by Transok Gas
Processing Company.

         (e) Notwithstanding any other provision of this Agreement to the
contrary (including Sections 6.06 and 8.03) the Purchaser agrees to indemnify
and hold harmless the Seller from and against any and all Losses (or Proceedings
in respect thereof) that arise out of, are based upon or are related in any way
to the Processing Plants Sale, the Processing Plants Lease, if any, or any
Processing Plants Transaction Documents unless such Losses would have arisen or
been incurred if the Processing Plants Sale, the Processing Plants Lease, if
any, or any Processing Plants Transaction Documents had not been entered into
and the Merger had occurred with the Processing Plants still being owned by
Transok Gas Processing Company. This indemnification obligation shall apply to
Losses of every kind or character whatsoever, including Losses related to third
party claims asserted against the Seller that arise by operation of statute,
contract law, tort law or otherwise.
THIS INDEMNIFICATION OBLIGATION IS INTENDED BY THE PARTIES TO APPLY
EVEN IF IT HAS THE EFFECT OF EXCULPATING AND INDEMNIFYING THE SELLER
FROM LEGAL RESPONSIBILITY FOR THE CONSEQUENCES OF ITS INTENTIONAL
OR NEGLIGENT CONDUCT. Section 8.02(b), (d), (e) and (f) shall apply to the
indemnification of Losses pursuant to this subsection as if such Losses were
indemnified against pursuant to the first sentence of Section 8.02(a). For
purposes of this Section 6.16, the term "Losses" shall include any increase in
tax, interest or penalty that is payable to any taxing jurisdiction by reason of
such jurisdiction's characterization of the Processing Plants Sale and the
Processing Plants Lease, if any, as a sale rather than a financing transaction
for taxation purposes, including all state and local transfer, sales, use or
other similar taxes. The Seller shall file all of its Tax Returns and related
forms consistent with the parties' intent that the Processing Plants Sale is a
financing transaction and not a sale for tax purposes.

         (f) The Purchaser agrees to reimburse the Seller for any legal or other
expenses incurred by it in connection with investigating or defending against
any Losses or Proceedings against which it is indemnified in subsection (e) of
this Section."

         13.      Section 7.02(f) of the Merger Agreement is deleted in its 
entirety.

         14.      The following defined terms are added to Annex A to the Merger
Agreement:

                                        6

         "Bill of Sale" shall have the meaning ascribed to such term in Section
6.16(a).

6.16(c).

         "Processing Plants Lease" shall have the meaning ascribed to such term
in Section 6.16(a).

         "Processing Plants Transaction Documents" shall have the meaning

         15. This Amendment may be executed in any number of counterparts, each
of which when so executed shall be deemed an original but all of which together
shall constitute one and the same instrument.

         16. Unless otherwise defined herein, capitalized terms used herein
shall have the meanings ascribed to such terms in the Merger Agreement.

         IN WITNESS WHEREOF, each of the parties hereto has caused this
Amendment to be signed in its corporate name by its duly authorized officer, all
on the date first above written.
