              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS


1.  SIGNIFICANT ACCOUNTING POLICIES


THE COMPANY AND TU ELECTRIC
- ---------------------------

  Basis of Presentation -- The condensed consolidated financial statements of
Texas Utilities Company (Company) and its subsidiaries and Texas Utilities
Electric Company and its subsidiaries (TU Electric) have been prepared on the
same basis as those in the 1996 Annual Reports of the Company and TU Electric on
Form 10-K and, in the opinion of the Company or TU Electric, as the case may be,
all adjustments (constituting only normal recurring accruals) necessary to a
fair presentation of the results of operation and financial position have been
included therein.  The statements are presented pursuant to the rules and
regulations of the Securities and Exchange Commission (SEC).  Certain
information and footnote disclosures normally included in annual consolidated
financial statements prepared in accordance with generally accepted accounting
principles have been omitted pursuant to such rules and regulations.

  These condensed consolidated financial statements, and notes thereto, should
be considered in conjunction with the consolidated financial statements, and the
notes thereto, of the Company and TU Electric included in the 1996 Annual
Reports of the Company and TU Electric on Form 10-K, and the information under
Management's Discussion and Analysis of Financial Condition and Results of
Operation herein.  The Company and TU Electric each believes that its respective
disclosures are adequate to make the information presented not misleading.
Certain previously reported amounts have been reclassified to conform to current
classifications.

  Use of Estimates -- The preparation of the Company's and TU Electric's
condensed consolidated financial statements, in conformity with generally
accepted accounting principles, requires management to make estimates and
assumptions about future events that affect the reporting and disclosure of
assets and liabilities at the balance sheet dates and the reported amounts of
revenue and expense during the periods covered by the condensed consolidated
financial statements.  In the event estimates and/or assumptions prove to be
different from actual amounts, adjustments are made in subsequent periods to
reflect more current information.  No material adjustments were made to previous
estimates during the current period.

THE COMPANY
- -----------

  Consolidation -- The condensed consolidated financial statements include the
Company and all of its majority-owned subsidiaries:

<TABLE> 

<S>                                                     <C>

TU Electric                                             Texas Utilities Services Inc. (TU Services)
Texas Utilities Australia Pty. Ltd. (TU Australia)      Texas Utilities Properties Inc. (TU Properties)
Southwestern Electric Service Company (SESCO)           Texas Utilities Communications Inc. (TU Communications)
Texas Utilities Fuel Company (Fuel Company)             Basic Resources Inc. (Basic)
Texas Utilities Mining Company (Mining Company)         Chaco Energy Company (Chaco)

</TABLE> 
 

  All significant intercompany items and transactions have been eliminated in
consolidation.  Investments in significant unconsolidated affiliates are
accounted for by the equity method.

TU ELECTRIC
- -----------

  Consolidation  -- The condensed consolidated financial statements of TU
Electric include its subsidiaries, all of which are business trusts.  All
significant intercompany items and transactions have been eliminated in
consolidation.

  Income Taxes -- Effective January 1, 1997, TU Electric's state franchise tax
status changed from taxes based on net taxable capital to taxes based on net
taxable earned surplus.  Net taxable earned surplus is based on the federal
income tax return.  TU Electric has determined that a portion of the taxes
calculated under the new tax status method is, in effect,  a state income tax.
As a result, TU Electric recorded an accumulated deferred tax liability,
partially offset by a corresponding regulatory asset.

2.  SHORT-TERM FINANCING

THE COMPANY AND TU ELECTRIC
- ---------------------------

  In April 1997, the Company, TU Electric and TUC Holding Company (TUC), the new
holding company resulting from the completion of the merger transactions
involving the Company and ENSERCH Corporation (ENSERCH) (see Note 7), entered
into new credit agreements (Credit Agreements) with a group of commercial banks.
The Credit Agreements replaced prior lines of credit with two new facilities.
Facility A provides for short-term borrowings aggregating up to $570,000,000
outstanding at any one time at variable interest rates and terminates April 23,
1998.  Facility B provides for short-term borrowings aggregating up to
$1,330,000,000 outstanding at any one time at variable interest rates and
terminates April 24, 2002.  Prior to the effective date of the merger
transactions involving the Company and ENSERCH, the Company's and TU Electric's
borrowings under Facilities A and B were limited to an aggregate of up to
$1,500,000,000 outstanding at any one time.  Upon completion of the merger
transactions involving the Company and ENSERCH: (i)  TUC will replace the
Company as a borrower, (ii)  ENSERCH is expected to become a party to the Credit
Agreements with ENSERCH borrowings under both facilities limited to an aggregate
of up to $650,000,000 outstanding at any one time, and (iii) TUC's, TU
Electric's and ENSERCH's borrowings under both facilities will be limited to an
aggregate of up to $1,900,000,000 outstanding at any one time. Borrowings under
these facilities will be used for working capital and other corporate purposes,
including commercial paper backup. The total of short-term borrowings authorized
by the Board of Directors of the Company at June 30, 1997 from banks or other
lenders, was $2,150,000,000.

3.  CAPITALIZATION

THE COMPANY
- -----------

COMMON STOCK

  The Company has purchased from a third party a note that was issued by the
Company's Employee Thrift Plan (Thrift Plan) to finance the purchase of shares
of common stock (LESOP Shares).  The purchase of the note was recorded by the
Company as a reduction to common stock equity.  LESOP Shares are outstanding
shares, but are held by the Thrift Plan trustee until allocated to accounts of
participants, at which time increases to common stock equity are recorded.
Allocations to participants' accounts during the six months ended June 30, 1997,
increased common stock equity by $4,047,000.

  In June 1997, the Company sold 47,000 shares of its authorized but unissued
common stock to the Long-Term Incentive Compensation Plan of Texas Utilities
Company System as approved at the Company's Annual Meeting of Shareholders held
on May 23, 1997.

PREFERRED STOCK

  In March 1997, the Company completed its tender offer for any and all shares
of 20 series of TU Electric's preferred stock and depositary shares.  The
Company funded the purchase of 3,989,640 shares of such stock at a total cost of
approximately $404,000,000 primarily through the issuance of commercial paper.
In May and June 1997, the Company sold such shares to TU Electric for
approximately $408,000,000.  (See TU Electric -- Preferred Stock below.)

TU ELECTRIC
- -----------

COMMON STOCK

  In June 1997, TU Electric purchased from the Company and retired 4,547,200
shares of its issued and outstanding common stock.

PREFERRED STOCK

  At June 30, 1997 and December 31, 1996, TU Electric had 17,000,000 shares of
preferred stock authorized by its articles of incorporation of which 1,624,240
and 7,101,879 shares were issued and outstanding, respectively.

               TEXAS UTILITIES ELECTRIC COMPANY AND SUBSIDIARIES
             NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

  During the six months ended June 30, 1997, TU Electric redeemed or purchased
5,477,639 shares of its preferred stock  (including the 3,989,640 shares
tendered to the Company and subsequently sold to TU Electric) with annual
dividend rates ranging from 4.00% to 9.64%.

TU ELECTRIC OBLIGATED, MANDATORILY REDEEMABLE, PREFERRED SECURITIES OF
SUBSIDIARY TRUSTS HOLDING SOLELY DEBENTURES OF TU ELECTRIC

  Three statutory business trusts, TU Electric Capital I, TU Electric Capital II
and TU Electric Capital III (each a TU Electric Trust) were established in 1995
as financing subsidiaries of TU Electric for the purposes, in each case, of
issuing common and preferred trust securities, with a liquidation preference of
$25 per unit, and holding Junior Subordinated Debentures issued by TU Electric
(Debentures).  In January 1997, two additional TU Electric Trusts, TU Electric
Capital IV and TU Electric Capital V, were established for the purposes, in each
case, of issuing common and preferred trust securities, with a liquidation
preference of $1,000 per unit, and  holding Debentures.  The Debentures  held
by each TU Electric Trust are its only assets. Each TU Electric Trust will use
interest payments received on the Debentures it holds to make cash distributions
on the trust securities it has issued.

  At June 30, 1997 and December 31, 1996, preferred and common trust securities
of each TU Electric Capital Trust were outstanding as follows:

LONG-TERM DEBT

  In July 1997, the Brazos River Authority, the Sabine River Authority of Texas
and the Trinity River Authority of Texas issued $92,290,000 aggregate principal
amount of Pollution Control Revenue Refunding Bonds due July 1, 2002
collateralized by TU Electric's First Mortgage Bonds. In February 1997, the
Brazos River Authority issued $106,350,000 aggregate principal amount of
Pollution Control Revenue Refunding Bonds due February 1, 2032 collateralized by
TU Electric's First Mortgage Bonds. All such bonds have variable interest rates
and are subject to mandatory tender and remarketing from time to time. The
remarketing of the bonds is supported by standby bond purchase agreements.
Scheduled payments of interest and of principal at maturity or on mandatory
redemption, upon the occurrence of certain events, are supported by insurance
policies. Interest rates on all the bonds are determined daily. At June 30,
1997, such rates ranged from 4.10% to 4.25%.

  During the six months ended June 30, 1997, TU Electric redeemed or reacquired
the following long-term debt:

4.  DERIVATIVE INSTRUMENTS

THE COMPANY AND TU ELECTRIC
- ---------------------------

  The Company's and TU Electric's operations involve managing market risks
related to changes in interest rates and, for the Company, foreign exchange and
commodity price exposures.  Derivative instruments including swaps and forward
contracts are used to reduce and manage a portion of those risks.  The Company's
and TU Electric's participations in derivative transactions have been designed
for hedging purposes and are not held or issued for trading purposes.

INTEREST RATE RISK MANAGEMENT

  At June 30, 1997, Eastern Energy Limited (Eastern Energy) had interest rate
swaps outstanding with respect to certain of its debt with an aggregate notional
amount of $868,452,000.  These swap agreements establish a mix of fixed and
variable interest rates on the outstanding debt and have remaining terms between
5 and 20 years.

  In February 1997, TU Electric entered into an interest rate swap agreement
with respect to preferred securities of TU Electric Capital IV, with a notional
principal amount of $100,000,000 expiring 2002 and a fixed interest rate of
7.183% per annum.

FOREIGN EXCHANGE RISK MANAGEMENT

  The Company's foreign exchange exposures result from transactions denominated
in currencies other than the local currency of its foreign subsidiary.  At June
30, 1997, Eastern Energy had cross-currency swap agreements outstanding with an
aggregate notional amount of $325,716,000 expiring on various dates through
2016.

ELECTRICITY PRICE RISK MANAGEMENT

  Eastern Energy and the other distribution companies in Victoria purchase their
power from a competitive power pool operated by a statutory, independent
corporation.  Eastern Energy purchases about 95% of its energy from this pool,
the cost of which is based on spot market price.  Eastern Energy has entered
into wholesale market contracts to cover a substantial majority of its
forecasted load through the end of 2000.  These contracts fix the price of
energy within a certain range for the purpose of hedging or protecting against
fluctuations in the spot market price.  Eastern Energy's contracts related to
its forecasted contestable and franchise load cover a notional volume of
approximately 18 million MWh's for 1997 through 2000. Under these contracts,
payments are made between Eastern Energy and the generators representing the
difference between the wholesale electricity market price and the contract
price.  The net payable or receivable is recognized in earnings as adjustments
to purchased power expense in the period the related transactions are completed.

CREDIT RISK

  Credit risk relates to the risk of loss that the Company and TU Electric would
incur as a result of nonperformance by counterparties to their respective
derivative instruments.  The Company and TU Electric believe the risk of
nonperformance by counterparties is minimal.

5.  REGULATION AND RATES

TU ELECTRIC
- -----------

  In late 1996, as part of its regular earnings monitoring process, the Public
Utility Commission of Texas (PUC) staff, after reviewing the 1995 Electric
Investor-Owned Utilities Earnings Report of TU Electric, advised the PUC that it
believed TU Electric was earning in excess of a reasonable rate of return, and
the PUC and TU Electric subsequently began discussions concerning possible
remedies.  It was decided to limit negotiations to a resolution of issues
concerning TU Electric's earnings through 1997, and discussion of a long-term
resolution was deferred until it could be determined whether the 1997 Texas
legislature, then in session, would enact applicable legislation.

  In July 1997, the PUC issued its final written order approving TU Electric's
proposal to make a one-time $80 million refund to its customers in August 1997
billings and to leave rates unchanged during the remainder of 1997.  TU Electric
recorded the charge in July 1997.  The proposal was the result of a joint
stipulation in which TU Electric was joined by the PUC General Counsel, on
behalf of the PUC Staff and the public interest, the Office of Public Utility
Counsel, the state agency charged with representing the interests of residential
and small commercial customers, and the Coalition of Cities served by TU
Electric.  TU Electric is continuing its negotiations with respect to a longer-
term settlement of the issues, including a resolution of the appeals of TU
Electric's last two general rate cases.  TU Electric is unable to predict the
outcome of any of these negotiations.

  Also in July 1997, the PUC ruled on TU Electric's petition seeking final
reconciliation of all eligible fuel and purchased power expenses incurred during
the reconciliation period of July 1, 1992 through June 30, 1995 (approximately
$4.7 billion). In the ruling, the PUC disallowed approximately $69 million of
eligible fuel related costs incurred during the reconciliation period.  The
majority of the disallowance (approximately $67 million) is related to
replacement fuel costs as a result of the November 1993 collapse of the
emissions chimney serving Unit 3 of the Monticello lignite-fueled generating
station.  In addition, the PUC ruled that approximately $10 million from the
gain on sale of sulfur dioxide allowances should be deferred and reconsidered at
a future date.  TU Electric is still reviewing the ruling, but strongly
disagrees with the disallowance and will continue to vigorously defend its
position.  It is anticipated that TU Electric will file a motion for rehearing.
A final written order from the PUC is expected in the near future, the terms of
which could vary from the ruling.  TU Electric will record the charge upon
receipt of a final written order from the PUC.

  TU Electric, in July 1997, petitioned the PUC for and received interim
approval of a fuel refund to customers of approximately $67 million, including
interest, in over-collected fuel costs for the period October 1995 through May
1997. Such over-collection was primarily due to TU Electric's ability to use
less expensive nuclear fuel and purchased power to offset a higher-priced
natural gas market during the period.  Refunds will be included in August 1997
billings.

6.  COMMITMENTS AND CONTINGENCIES

TU ELECTRIC
- -----------

COOLING WATER CONTRACTS

  TU Electric has entered into contracts with public agencies to purchase
cooling water for use in the generation of electric energy.  In connection with
certain contracts, TU Electric has agreed, in effect, to guarantee the
principal, $32,365,000 at June 30, 1997, and interest on bonds issued to finance
the reservoirs from which the water is supplied.  The bonds mature at various
dates through 2011 and have interest rates ranging from 5-1/2% to 7%.  TU
Electric is required to make periodic payments equal to such principal and
interest, including amounts assumed by a third party and reimbursed to TU
Electric. In  addition, TU Electric is obligated to pay certain variable costs
of operating and maintaining the reservoirs. TU Electric has assigned to a
municipality all contract rights and obligations of TU Electric in connection
with $74,780,000 remaining principal amount of bonds at June 30, 1997, issued
for similar purposes which had previously been guaranteed by TU Electric. TU
Electric is, however, contingently liable in the unlikely event of default by
the municipality.

NUCLEAR DECOMMISSIONING AND DISPOSAL OF SPENT FUEL

  TU Electric has established a reserve, charged to depreciation expense and
included in accumulated depreciation, for the decommissioning of Comanche Peak
nuclear generating station (Comanche Peak), whereby decommissioning costs are
being recovered from customers over the life of the plant and deposited in an
external trust fund (included in other investments).  At June 30, 1997, such
reserve totaled $108,659,000 which includes an accrual of $9,089,000 and
$18,179,000 for the six and twelve months ended June 30, 1997, respectively.  As
of June 30, 1997, the market value of assets in the external trust fund for
decommissioning of Comanche Peak was $139,360,000.  Any difference between the
market value of the external trust fund and the decommissioning reserve that
represents unrealized gains or losses of the trust fund is treated as a
regulatory liability or a regulatory asset.  Realized earnings on funds
deposited in the external trust are recognized in the reserve.  Based on a site-
specific study during 1992 using the prompt dismantlement method and then-
current dollars, decommissioning costs for Comanche Peak Unit 1, and Unit 2 and
common facilities were estimated to be $255,000,000 and $344,000,000,
respectively. Decommissioning activities are projected to begin in 2030 and 2033
for

Comanche Peak Unit 1, and Unit 2 and common facilities, respectively.  TU
Electric is recovering such costs based upon the 1992 study through rates placed
in effect under its January 1993 rate increase request. An updated site-specific
study will be performed and completed by the end of 1997.  Actual
decommissioning costs are expected to differ from estimates due to changes in
the assumed dates of decommissioning activities, regulatory requirements,
technology and costs of labor, materials and equipment.

THE COMPANY AND TU ELECTRIC
- ---------------------------

GENERAL

  In addition to the above, the Company and TU Electric are involved in various
legal and administrative proceedings which, in the opinion of the management of
each, should not have a material effect upon its financial position, results of
operation or cash flows.

7.  SUBSEQUENT EVENT

THE COMPANY
- -----------

  On August 5, 1997, the merger transactions (Merger) provided for in a
previously announced agreement between the Company and ENSERCH were completed.
At the effective time of the Merger:  (i) the Company and ENSERCH merged into
wholly owned subsidiaries of TUC, which, as a result, now owns all the common
stock of the Company and of ENSERCH, (ii) TUC changed its name to Texas
Utilities Company, (iii) the Company changed its name to Texas Energy
Industries, Inc., (iv) each share of the Company's common stock was
automatically converted into one share of common stock of TUC, and (v) each
share of common stock of ENSERCH was automatically converted into 0.225 share of
common stock of TUC with cash issued in lieu of fractional shares.  The share
conversions were tax-free transactions.

  Under the terms of the Merger, TUC acquired Lone Star Gas Company (Lone Star
Gas) and Lone Star Pipeline Company (Lone Star Pipeline), the local distribution
and pipeline divisions of ENSERCH and other ENSERCH businesses, excluding
Enserch Exploration Inc.  Lone Star Gas is one of the largest gas distribution
companies in the United States and the largest in Texas, serving over 1.3
million customers and providing service through over 23,500 miles of
distribution mains.  Lone Star Pipeline has one of the largest pipelines in the
United States, consisting of 9,200 miles of gathering and transmission pipelines
in Texas.  Also included in the acquisition are ENSERCH's subsidiaries engaged
in natural gas processing, natural gas marketing and independent power
production.

  In the Merger, approximately 15,861,000 shares of TUC common stock, with a
market value of approximately $550 million at the time of the Merger, were
issued to former holders of ENSERCH common stock.  Approximately $1.3 billion of
ENSERCH's debt and preferred stock will remain outstanding.  The acquisition of
ENSERCH will be accounted for as a purchase business combination.

INDEPENDENT ACCOUNTANTS' REPORT

Texas Utilities Company:

We have reviewed the accompanying condensed consolidated balance sheet of Texas
Utilities Company and subsidiaries (the Company) as of June 30, 1997, and the
related condensed statements of consolidated income for the three-month, six-
month and twelve-month periods ended June 30, 1997 and 1996, and of consolidated
cash flows for the six-month periods ended June 30, 1997 and 1996.  These
financial statements are the responsibility of the Company's management.

We conducted our review in accordance with standards established by the American
Institute of Certified Public Accountants.  A review of interim financial
information consists principally of applying analytical procedures to financial
data and making inquiries of persons responsible for financial accounting
matters.  It is substantially less in scope than an audit in accordance with
generally accepted auditing standards, the objective of which is the expression
of an opinion regarding the financial statements taken as a whole.  Accordingly,
we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should
be made to such condensed consolidated financial statements for them to be in
conformity with generally accepted accounting principles.

We have previously audited, in accordance with generally accepted auditing
standards, the consolidated balance sheet of the Company as of December 31,
1996, and the related consolidated statements of income, retained earnings and
cash flows for the year then ended (not presented herein); and in our report
dated March 12, 1997, we expressed an unqualified opinion on those consolidated
financial statements, which opinion included an explanatory paragraph concerning
the Company's change in accounting for the impairment of long-lived assets and
long-lived assets to be disposed of.  In our opinion, the information set forth
in the accompanying condensed consolidated balance sheet as of December 31,
1996, is fairly stated in all material respects in relation to the consolidated
balance sheet from which it has been derived.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATION

FORWARD-LOOKING STATEMENTS

  This report and other presentations made by Texas Utilities Company (Company)
and its subsidiaries or Texas Utilities Electric Company and its subsidiaries
(TU Electric) contain forward-looking statements within the meaning of Section
21E of the Securities Exchange Act of 1934, as amended.  Although the Company
and TU Electric each believes that in making any such statement its expectations
are based on reasonable assumptions, any such statement involves uncertainties
and is qualified in its entirety by reference to the following important factors
that could cause the actual results of the Company or TU Electric to differ
materially from those projected in such forward-looking statement: (i)
prevailing governmental policies and regulatory actions, including those of the
Federal Energy Regulatory Commission, the Public Utility Commission of Texas
(PUC), the Nuclear Regulatory Commission, and, in the case of the Company, the
Office of the Regulator General of Victoria, Australia, with respect to allowed
rates of return, industry and rate structure, purchased power and investment
recovery, operations of nuclear generating facilities, acquisitions and disposal
of assets and facilities, operation and construction of plant facilities,
decommissioning costs, present or prospective wholesale and retail competition,
changes in tax laws and policies and changes in and compliance with
environmental and safety laws and policies, (ii) weather conditions and other
natural phenomena, (iii) unanticipated population growth or decline, and changes
in market demand and demographic patterns, (iv) competition for retail and
wholesale customers, (v) pricing and transportation of crude oil, natural gas
and other commodities, (vi) unanticipated changes in interest rates, rates of
inflation or in foreign exchange rates, (vii) unanticipated changes in operating
expenses and capital expenditures, (viii) capital market conditions, (ix)
competition for new energy development opportunities, and (x) legal and
administrative proceedings and settlements.

  Any forward-looking statement speaks only as of the date on which such
statement is made, and neither the Company nor TU Electric undertakes any
obligation to update any forward-looking statement to reflect events or
circumstances after the date on which such statement is made or to reflect the
occurrence of unanticipated events.  New factors emerge from time to time and it
is not possible for the Company or TU Electric to predict all of such factors,
nor can they assess the impact of each such factor or the extent to which any
factor, or combination of factors, may cause results to differ materially from
those contained in any forward-looking statement.

GENERAL

  Certain comparisons in this Quarterly Report on Form 10-Q have been affected
by the December 1995 acquisition of Eastern Energy Limited (Eastern Energy) by
Texas Utilities Australia Pty. Ltd. (TU Australia), a wholly-owned subsidiary of
the Company.  The results of operation of Eastern Energy are included only for
the periods subsequent to acquisition.

FINANCIAL CONDITION

THE COMPANY AND TU ELECTRIC
- ---------------------------

LIQUIDITY AND CAPITAL RESOURCES

  For information concerning liquidity and capital resources, see Item 7.
Management's Discussion and Analysis of Financial Condition and Results of
Operation in the Company and TU Electric Annual Reports on Form 10-K for the
year 1996 (1996 Form 10-K).  Quarterly results presented herein are not
necessarily indicative of expectations for a full year's operations because of
seasonal and other factors, including variations in maintenance and other
operating expense patterns. No significant changes or events which might affect
the financial condition of the Company and its subsidiaries (System Companies)
have occurred subsequent to year-end other than as disclosed in other reports of
the Company and TU Electric or included herein.

  External funds of a permanent or long-term nature are obtained through the
issuance of common stock, preferred stock, preferred securities and long-term
debt by the System Companies.  The capitalization ratios of the Company and its
subsidiaries at June 30, 1997 consisted of approximately 54% long-term debt, 6%
preferred securities of trusts, 1% preferred stock and 39% common stock equity.
The capitalization ratios of TU Electric at June 30, 1997 consisted of
approximately 46% long-term debt, 7% preferred securities of trusts, 1%
preferred stock and 46% common stock equity.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATION

  In July 1997, the Brazos River Authority, the Sabine River Authority of Texas
and the Trinity River Authority of Texas issued $92,290,000 aggregate principal
amount of Pollution Control Revenue Refunding Bonds due July 1, 2002
collateralized by TU Electric's First Mortgage Bonds. In February 1997, the
Brazos River Authority issued $106,350,000 aggregate principal amount of
Pollution Control Revenue Refunding Bonds due February 1, 2032 collateralized by
TU Electric's First Mortgage Bonds. All such bonds have variable interest rates
and are subject to mandatory tender and remarketing from time to time. The
remarketing of the bonds is supported by standby bond purchase agreements.
Scheduled payments of interest and of principal at maturity or on mandatory
redemption, upon the occurrence of certain events, are supported by insurance
policies. Interest rates on all the bonds are determined daily. Currently, such
rates range from 3.40% to 3.55%.

  To date in 1997, the System Companies have redeemed, reacquired or made
principal payments of $1,191,699,000 (including $1,188,134,000 for TU Electric)
on long-term debt and preferred stock. In July 1997, TU Electric completed its
purchase of 4,547,200 shares ($316,416,000) of its issued and outstanding common
stock from the Company.

  In March 1997, the Company completed its tender offer for any and all shares
of 20 series of TU Electric's preferred stock and depositary shares.  The
Company funded the purchase of 3,989,640 shares of such stock at a total cost of
approximately $404,000,000 primarily through the issuance of commercial paper.
In May and June 1997, the Company sold such shares to TU Electric for
approximately $408,000,000.  Upon purchase by TU Electric, the shares were
retired. TU Electric's purchase of the shares was funded with excess proceeds
from the sale of capital securities in early 1997.

  In April 1997, the Company, TU Electric and TUC Holding Company (TUC), the new
holding company resulting from the completion of the merger transactions
involving the Company and ENSERCH Corporation (ENSERCH) (see Note 7 to Condensed
Consolidated Financial Statements), entered into new credit agreements (Credit
Agreements) with a group of commercial banks.  The Credit Agreements replaced
prior lines of credit with two new facilities.  Facility A provides for short-
term borrowings aggregating up to $570,000,000 outstanding at any one time at
variable interest rates and terminates April 23, 1998.  Facility B provides for
short-term borrowings aggregating up to $1,330,000,000 outstanding at any one
time at variable interest rates and terminates April 24, 2002.  Prior to the
effective date of the merger transactions involving the Company and ENSERCH, the
Company's and TU Electric's borrowings under Facilities A and B were limited to
an aggregate of up to $1,500,000,000 outstanding at any one time. Upon
completion of the merger transactions involving the Company and ENSERCH: (i) TUC
will replace the Company as a borrower, (ii) ENSERCH is expected to become a
party to the Credit Agreements with ENSERCH borrowings under both facilities
limited to an aggregate of up to $650,000,000 outstanding at any one time, and
(iii) TUC's, TU Electric's and ENSERCH's borrowings under both facilities will
be limited to an aggregate of up to $1,900,000,000 outstanding at any one time.
Borrowings under these facilities will be used for working capital and other
corporate purposes, including commercial paper backup. The total of short-term
borrowings authorized by the Board of Directors of the Company at June 30, 1997
from banks or other lenders, was $2,150,000,000.

  The System Companies expect to issue additional debt and equity securities as
needed, including (i) the possible future sale by TU Electric of up to
$448,850,000 principal amount of First Mortgage Bonds and debt securities, or a
combination thereof, currently registered with the Securities and Exchange
Commission (SEC) for offering pursuant to Rule 415 under the Securities Act of
1933 and (ii) the possible future sale by TU Electric of up to 250,000 shares of
Cumulative Preferred Stock ($100 liquidation value) similarly registered.

  The Company's and TU Electric's operations involve managing market risks
related to changes in interest rates and, for the Company, foreign exchange and
commodity price exposures.  Derivative instruments including swaps and forward
contracts are used to reduce and manage a portion of those risks.  The Company's
and TU Electric's participations in derivative transactions have been designed
for hedging purposes and are not held or issued for trading purposes.  The
Company's foreign exchange exposures result from transactions denominated in
currencies other than the local currency of its foreign subsidiary.  As of June
30, 1997, the aggregate notional amount of such exposure was $325,716,000.  The
Company enters into currency swaps to reduce foreign exchange exposure.  As of
June 30, 1997, net deferred gains and losses associated with the currency swaps
were not material.  Credit risk relates to the risk of loss that the Company and
TU Electric would incur as a result of nonperformance by counterparties to their
respective derivative instruments.  The Company and TU Electric believe the risk
of nonperformance by counterparties is minimal.  For other information regarding
Derivative Instruments, see Note 4 to Condensed Consolidated Financial
Statements.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATION

REGULATION, RATES AND COMPETITION

  Under the current regulatory environment, TU Electric and Southwestern
Electric Service Company  (SESCO) are subject to the provisions of Statement of
Financial Accounting Standards No. 71, "Accounting for the Effects of Certain
Types of Regulation" (SFAS 71). In the event the companies no longer meet the
criteria for application of SFAS 71 due to significant changes in regulation or
competition, the companies would discontinue the application of SFAS 71. If a
portion of either company's operations continues to meet the criteria for
application of SFAS 71, only that portion would be subject to SFAS 71 treatment.
Should significant changes in regulation or competition occur, TU Electric and
SESCO would be required to assess the recoverability of other assets, including
plant, and, if impaired, to write down the assets to reflect their fair market
value. Neither TU Electric nor SESCO can predict whether or to what extent
changes in the business environment may occur requiring the partial or complete
discontinuation of SFAS 71 application.

  In late 1996, as part of its regular earnings monitoring process, the PUC
staff, after reviewing the 1995 Electric Investor-Owned Utilities Earnings
Report of TU Electric, advised the PUC that it believed TU Electric was earning
in excess of a reasonable rate of return, and the PUC and TU Electric
subsequently began discussions concerning possible remedies.  It was decided to
limit negotiations to a resolution of issues concerning TU Electric's earnings
through 1997, and discussion of a long-term resolution was deferred until it
could be determined whether the 1997 Texas legislature, then in session, would
enact applicable legislation.

  In July 1997, the PUC issued its final written order approving TU Electric's
proposal to make a one-time $80 million refund to its customers in August 1997
billings and to leave rates unchanged during the remainder of 1997.  TU Electric
recorded the charge in July 1997.  The proposal was the result of a joint
stipulation in which TU Electric was joined by the PUC General Counsel, on
behalf of the PUC Staff and the public interest, the Office of Public Utility
Counsel, the state agency charged with representing the interests of residential
and small commercial customers, and the Coalition of Cities served by TU
Electric.  TU Electric is continuing its negotiations with respect to a longer-
term settlement of the issues, including a resolution of the appeals of TU
Electric's last two general rate cases.  TU Electric is unable to predict the
outcome of any of these negotiations.

  Also in July 1997, the PUC ruled on TU Electric's petition seeking final
reconciliation of all eligible fuel and purchased power expenses incurred during
the reconciliation period of July 1, 1992 through June 30, 1995 (approximately
$4.7 billion).  In the ruling, the PUC disallowed approximately $69 million of
eligible fuel related costs incurred during the reconciliation period.  The
majority of the disallowance (approximately $67 million) is related to
replacement fuel costs as a result of the November 1993 collapse of the
emissions chimney serving Unit 3 of the Monticello lignite-fueled generating
station.  In addition, the PUC ruled that approximately $10 million from the
gain on sale of sulfur dioxide allowances should be deferred and reconsidered at
a future date.  TU Electric is still reviewing the ruling, but strongly
disagrees with the disallowance and will continue to vigorously defend its
position.  It is anticipated that TU Electric will file a motion for rehearing.
A final written order from the PUC is expected in the near future, the terms of
which could vary from the ruling. TU Electric will record the charge upon
receipt of a final written order from the PUC.

  TU Electric, in July 1997, petitioned the PUC for and received interim
approval of a fuel refund to customers of approximately $67 million, including
interest, in over-collected fuel costs for the period October 1995 through May
1997. Such over-collection was primarily due to TU Electric's ability to use
less expensive nuclear fuel and purchased power to offset a higher-priced
natural gas market during the period.  Refunds will be included in August 1997
billings.

  In order to remain competitive, the Company and TU Electric are aggressively
managing their operating costs and capital expenditures through streamlined
business processes and are developing and implementing strategies to address an
increasingly competitive environment.  These strategies include initiatives to
improve their return on corporate assets and to maximize shareholder value
through new marketing programs, creative rate design, and new business
opportunities. Additional initiatives under consideration include the potential
disposition or alternative utilization of existing assets and the restructuring
of strategic business units.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATION

  While TU Electric and SESCO have experienced competitive pressures in the
wholesale market resulting in a small loss of load for TU Electric since the
beginning of 1993, wholesale sales represented a relatively low percentage of TU
Electric's consolidated operating revenues for the three-, six- and twelve-month
periods ended June 30, 1997. TU Electric and SESCO are unable to predict the
extent of future competitive developments in either the wholesale or retail
markets or what impact, if any, such developments may have on their operations.

CAPITAL EXPENDITURES

   The re-evaluation of growth expectations, the effects of inflation,
additional regulatory requirements and the availability of fuel, labor,
materials and capital may result in changes to the estimated construction costs
and dates of completion in the Company's and TU Electric's construction programs
(see Item 2.  Properties -- Capital Expenditures in the 1996 Form 10-K).
Commitments in connection with the construction program are generally revocable
subject to reimbursement to manufacturers for expenditures incurred or other
cancellation penalties.

   The Company and TU Electric each plans to seek new investment opportunities
from time to time when it concludes that such investments are consistent with
its business strategies and will likely enhance the long-term returns to
shareholders. The timing and amounts of any specific new business investment
opportunities are presently undetermined.

THE COMPANY
- -----------
BUSINESS MERGERS AND ACQUISITIONS

  On August 5, 1997, the merger transactions (Merger) provided for in a
previously announced agreement between the Company and ENSERCH were completed.
At the effective time of the Merger:  (i) the Company and ENSERCH merged into
wholly owned subsidiaries of TUC, which, as a result, now owns all the common
stock of the Company and of ENSERCH, (ii) TUC changed its name to Texas
Utilities Company, (iii) the Company changed its name to Texas Energy
Industries, Inc., (iv) each share of the Company's common stock was
automatically converted into one share of common stock of TUC, and (v) each
share of common stock of ENSERCH was automatically converted into 0.225 share of
common stock of TUC with cash issued in lieu of fractional shares.  The share
conversions were tax-free transactions.

  Under the terms of the Merger, TUC acquired Lone Star Gas Company (Lone Star
Gas) and Lone Star Pipeline Company (Lone Star Pipeline), the local distribution
and pipeline divisions of ENSERCH and other ENSERCH businesses, excluding
Enserch Exploration Inc.  Lone Star Gas is one of the largest gas distribution
companies in the United States and the largest in Texas, serving over 1.3
million customers and providing service through over 23,500 miles of
distribution mains.  Lone Star Pipeline has one of the largest pipelines in the
United States, consisting of 9,200 miles of gathering and transmission pipelines
in Texas.  Also included in the acquisition are ENSERCH's subsidiaries engaged
in natural gas processing, natural gas marketing and independent power
production.

  In the Merger, approximately 15,861,000 shares of TUC common stock, with a
market value of approximately $550 million at the time of the Merger, were
issued to former holders of ENSERCH common stock.  Approximately $1.3 billion of
ENSERCH's debt and preferred stock will remain outstanding.  The acquisition of

RESULTS OF OPERATION

THE COMPANY
- -----------

  For the three-, six- and twelve-month periods ended June 30, 1997, the
Company's consolidated net income, excluding the after-tax effect of the 1995
asset impairment representing approximately $802 million ($316 million for TU
Electric), decreased approximately 21%, 16% and 9% as compared to the respective
periods ended June 30, 1996.  For the Company and TU Electric, from which most
of the Company's consolidated earnings is derived, the major factor affecting
earnings for all current periods was milder weather conditions as compared to
the respective prior periods.

  The Company's condensed statement of consolidated income for the twelve months
  ended June 30, 1997, is affected by a full twelve month's results of operation
  of Eastern Energy, which was acquired by TU Australia in December 1995.

</TABLE>

  Total energy sales (including unbilled energy sales) for the three-month and
six-month periods decreased by approximately 7% and 4% respectively, primarily
as a result of milder weather conditions.  Total energy sales (including
unbilled energy sales) did not change significantly for the twelve-month period.
The decrease in base rate revenue for all periods is due primarily to milder
weather conditions. The increase in transmission service revenue for the three-,
six- and twelve-month periods is due to the recognition of revenues from
implementing the PUC's Open Access Transmission Rule.

  Fuel revenue for the three-month and six-month periods decreased as a result
of decreases in energy sales.  The increase in fuel revenue for the twelve-month
period was primarily due to increases in spot market gas prices.

  Fuel and purchased power expense for the three-month and six-month periods
decreased 11% and 6%, respectively, and increased 4% for the twelve-month
period.  The decrease in the three-month and six-month periods was primarily due
to decreased energy sales.  The increase in the twelve-month period was
primarily due to increased spot market gas prices as compared to the prior
period.

  Other income and (deductions) -- net was affected for the three-, six- and
twelve-month periods by decreases in non-utility property expenses.

  Income tax benefits related to other income (loss) decreased for the three-
month and six-month periods primarily due to an IRS audit adjustment reflected
in the respective prior periods.  The decrease for the six-month period was
partially offset by the initial effect of the implementation of a change in TU
Electric's state franchise tax status effective January 1, 1997 (see Note 1 to
Condensed Consolidated Financial Statements).  The resulting increase in TU
Electric's effective income tax rate increased the value of its deferred tax
assets.

  Interest on mortgage bonds decreased as compared to the prior periods due to
reduced interest requirements resulting from TU Electric's refinancing efforts.
Decreases in interest on other long-term debt for the three-, six- and twelve-
month periods were affected by the prepayment in August and September 1996 of TU
Electric's borrowings under a term credit agreement.  The decrease in interest
on other long-term debt for the twelve-month period was also affected  by  the
prepayment of TU Electric's promissory note to Brazos Electric Power Cooperative
in October 1995. Other interest decreased for the three-, six-, and twelve-month
periods due primarily to an interest payment related to a settlement with the
Internal Revenue Service in June 1996.  Preferred securities of trusts
distributions resulted from the issuance, in December 1995 and January 1997, of
TU Electric obligated, mandatorily redeemable, preferred securities of trusts.

  For the three-, six- and twelve-month periods, preferred stock dividends
decreased due primarily to the redemption of significant portions of TU
Electric's preferred stock.

ITEM 5.  OTHER INFORMATION

THE COMPANY
- -----------

   On August 5, 1997, the merger transactions (Merger) provided for in a
previously announced agreement between the Company and ENSERCH Corporation
(ENSERCH) were completed.  At the effective time of the Merger:  (i) the Company
and ENSERCH merged into wholly owned subsidiaries of TUC, which, as a result,
now owns all the common stock of the Company and of ENSERCH, (ii) TUC changed
its name to Texas Utilities Company, (iii) the Company changed its name to Texas
Energy Industries, Inc., (iv) each share of the Company's common stock was
automatically converted into one share of common stock of TUC, and (v) each
share of common stock of ENSERCH was automatically converted into 0.225 share of
common stock of TUC with cash issued in lieu of fractional shares.  The share
conversions were tax-free transactions.

   Under the terms of the Merger, TUC acquired Lone Star Gas Company (Lone Star
Gas) and Lone Star Pipeline Company (Lone Star Pipeline), the local distribution
and pipeline divisions of ENSERCH and other ENSERCH businesses, excluding
Enserch Exploration Inc.  Lone Star Gas is one of the largest gas distribution
companies in the United States and the largest in Texas, serving over 1.3
million customers and providing service through over 23,500 miles of
distribution mains.  Lone Star Pipeline has one of the largest pipelines in the
United States, consisting of 9,200 miles of gathering and transmission pipelines
in Texas.  Also included in the acquisition are ENSERCH's subsidiaries engaged
in natural gas processing, natural gas marketing and independent power
production.

   In the Merger, approximately 15,861,000 shares of TUC common stock, with a
market value of approximately $550 million at the time of the Merger, were
issued to former holders of ENSERCH common stock.  Approximately $1.3 billion of
ENSERCH's debt and preferred stock will remain outstanding.  The acquisition of
ENSERCH will be accounted for as a purchase business combination.

                        Division A --- Preferred Stock

          1.  Series and Limits of Variations between Series.  Subject to the
              ----------------------------------------------                 
provisions of Division B of this Article VI which describe certain terms,
characteristics and relative rights and preferences of various series of
Preferred Stock which will be issuable at such time as the Board of Directors of
the Corporation shall provide (which provisions, however, shall not continue
effective as to any shares which are redeemed or purchased and thereby restored
to the status of authorized but unissued shares of Preferred Stock without
designation), the Preferred Stock may be divided into and issued in one or more
series from time to time as herein provided, each series to be so designated as
to distinguish the shares thereof from the shares of all other series and
classes.  The authorized number of shares of any such series, the designation of
such series, and the terms, characteristics and relative rights and preferences
thereof (in those respects in which the shares of one series may vary from the
shares of other series as herein provided) shall be established at any time
prior to the issuance thereof by resolution or resolutions of the Board of
Directors of the Corporation.  The Preferred Stock of all series shall be of the
same class and of equal rank and shall be identical in all respects, except that
there may be variations in the following particulars:

          (a)  The rate or rates at which dividends are to accrue on the shares
of such series, hereinafter referred to as the "authorized dividend rate";

          (b)  The terms and conditions upon which the shares of such series may
be redeemed, and the amount payable in respect to the shares of such series in
case of the redemption thereof at the option of the Corporation (the amount or
amounts so established being hereinafter referred to as the "authorized
redemption price"), and the amount payable in respect of the shares of such
series in case of the redemption thereof for any sinking fund of such series,
which amounts in respect of any series may, but need not, vary according to the
time or circumstances of such action or otherwise;

          (c)  The amount payable in respect of the shares of such series in
case of liquidation, dissolution or winding up of the Corporation (the amount or
amounts so established being hereinafter referred to as the "authorized
liquidation price"), and the amount payable, if any, in addition to the
authorized liquidation price for each series, in case such liquidation,
dissolution or winding up be voluntary (the amount or amounts so established
being hereinafter referred to as the "authorized liquidation premium"), which
amounts in respect of any series may, but need not, vary according to the time
or circumstances of such action or otherwise;

          (d)  Any requirement as to any sinking fund or purchase fund for, or
the redemption, purchase or other retirement by the Corporation of, the shares
of such series;

          (e)  The right, if any, to exchange or convert the shares of such
series into shares of any other series of the Preferred Stock or, to the extent
permitted by law, into securities of the Corporation or any other corporation or
other entity, and the rate or basis, time, manner and conditions of exchange or
conversion or the method by which the same shall be determined; and

          (f)   The voting rights, if any, of shares of such series.

          2.  Dividends.  Out of the assets of the Corporation legally available
              ---------                                                         
for dividends, the holders of the Preferred Stock of each series shall be
entitled, in preference to the holders of the Common Stock, to receive, but only
when and as declared payable by the Board of Directors, dividends at the
authorized dividend rate for such series,  and no more, payable quarterly on
February 1, May 1, August 1, and November 1 in each year, or otherwise as the
Board of Directors may 

                                       5
<PAGE>
 
determine or as set forth herein with respect to any particular series of
Preferred Stock, to shareholders of record as of a date not exceeding fifty (50)
days nor less than ten (10) days preceding such dividend payment dates, and such
dividends on the Preferred Stock shall be cumulative, so that, if in any past
dividend period or periods full dividends upon each series of the outstanding
Preferred Stock at the authorized dividend rate or rates therefor shall not have
been paid, the deficiency (without interest) shall be paid or declared and set
apart for payment before any dividends shall be paid upon or set apart for the
Common Stock (other than a dividend payable in Common Stock of the Corporation).
Dividends on all shares of the Preferred Stock of each series shall commence to
accrue and be cumulative from a date established by or upon authority of the
Board of Directors. Any dividends paid on the Preferred Stock in an amount less
than full cumulative dividends accrued or in arrears upon all Preferred Stock
outstanding shall, if more than one series be outstanding, be divided between
the different series in proportion to the aggregate amounts which would be
distributable to the Preferred Stock of each series if full cumulative dividends
were declared and paid thereon.

          3.  Preference on Liquidation.  In the event of any liquidation,
              -------------------------                                   
dissolution, or winding up of the Corporation, the holders of the Preferred
Stock of each series shall have a preference over the holders of the Common
Stock until the authorized liquidation price per share for such series, plus, in
case such liquidation, dissolution or winding up shall have been voluntary, the
authorized liquidation premium per share for such series, if any, together in
all cases with unpaid accumulated dividends, if any, shall have been paid or
distributed or declared and set apart for payment or distribution, but the
holders of the Preferred Stock shall be entitled to no further participation in
any such distribution.  If upon any such liquidation, dissolution or winding up,
the assets distributable among the holders of the Preferred Stock shall be
insufficient to permit the payment of the full preferential amounts aforesaid,
then said assets shall be distributed among the holders of each series of the
Preferred Stock then outstanding, ratably in proportion to the full preferential
amounts to which they are respectively entitled.  Nothing in this Section 3
shall be deemed to prevent the purchase or redemption of Preferred Stock in any
manner permitted by Section 4 of this Division A, nor shall anything in this
Section 3 be deemed to prevent the purchase or redemption by the Corporation of
shares of its Common Stock.  No such purchase or redemption shall be deemed to
be a liquidation, dissolution, or winding up of the Corporation or a
distribution of assets to its Common Shareholders within the meaning of this
Section 3 whether or not shares of Common Stock so redeemed or purchased shall
be retired, nor shall a consolidation or merger of the Corporation or a sale or
transfer of all or substantially all of its assets as an entirety be regarded as
a liquidation, dissolution or winding up of the Corporation within the meaning
of this Section 3.

          4.  Redemption and Repurchase.  The Corporation may at any time or
              -------------------------                                     
from time to time, by resolution of the Board of Directors, redeem all or any
part of the Preferred Stock, or of any series thereof, by paying in cash the
authorized redemption price applicable thereto plus the amount of unpaid
accumulated dividends, if any, to the date of such redemption.  If less than all
the shares of one series of Preferred Stock is to be redeemed, the shares to be
redeemed shall be selected ratably or by lot, in such manner as may be
prescribed by resolution of the Board of Directors.  Notice of such redemption
shall be mailed to each holder of redeemable shares being called, not less than
twenty (20) nor more than sixty (60) days before the date fixed for redemption,
at his address as it appears 

                                       6
<PAGE>
 
on the stock transfer books of the Corporation, with postage thereon prepaid.
Such notice of redemption of such shares shall set forth the series or part
thereof to be redeemed, the date fixed for redemption, the redemption price, and
the place at which the shareholders may obtain payment of the redemption price
upon surrender of their respective share certificates. The Corporation may at
any time revoke or rescind its decision to redeem preferred stock subsequent to
giving notice to the preferred shareholders but prior to the redemption date so
long as the Company shall not have deposited with the bank or trust company
and/or irrevocably directed the bank or trust company to apply, from moneys held
by it available to be used for the redemption of shares, an amount in cash
sufficient to redeem all of the shares. From and after the date fixed in any
such notice as the date of redemption, unless default shall be made by the
Corporation in providing funds sufficient for such redemption at the time and
place specified for the payment thereof pursuant to said notice or the
Corporation revokes its decision to redeem the preferred stock prior to the
redemption date, all dividends on the shares so redeemed shall cease to accrue,
and all rights of the holders of such shares as shareholders of the Corporation
except only the right to receive the redemption funds to which they are
entitled, shall cease and determine.

          The Corporation may, on or prior to the date fixed for any redemption,
deposit with any bank or trust company, or any entity duly appointed and acting
as a transfer agent of the Corporation, as a trust fund, a sum sufficient to
redeem shares called for redemption, with irrevocable instructions and authority
to such bank or trust company to give or complete the notice of redemption
thereof and to pay, on or after the date fixed for such redemption, to the
respective holders of shares, as evidenced by a list of holders of such shares
certified by an officer of the Corporation, the redemption price upon the
surrender of their respective share certificates, in the case of certificated
shares.  Thereafter, from and after the date fixed for redemption such shares
shall be deemed to be redeemed and dividends thereon shall cease to accrue after
such date fixed for redemption.  Such deposit shall be deemed to constitute full
payment of such shares to their holders. From and after the date such deposit is
made and such instruction given, such shares shall no longer be deemed to be
outstanding, and the holders thereof shall cease to be shareholders with respect
to such shares, and shall have no rights with respect thereto except the right
to receive from the bank or trust company payment of the redemption price of
such shares, without interest, upon the surrender of their respective
certificates therefor, and any right to convert such shares which may exist.  In
case the holders of such shares shall not, within six (6) years after such
deposit, claim the amount deposited for redemption thereof, such bank or trust
company shall upon demand pay over to the Corporation the balance of such amount
so deposited to be held in trust and such bank or trust company shall thereupon
be relieved of all responsibility to the holders thereof, and any interest
accrued thereon shall be paid over to the Corporation and become its property.

          Nothing in this Section 4 contained shall limit the right of the
Corporation to purchase or otherwise acquire shares of the Preferred Stock to
the extent permitted by law.

          Shares of Preferred Stock of the Corporation redeemed or purchased by
the Corporation shall be restored to the status of authorized but unissued
shares of Preferred Stock without designation, and may from time to time be
reissued as provided in Section 1 of this Division A.  All such redemptions and
purchases of Preferred Stock of the Corporation shall be effected in accordance
with the laws of the State of Texas governing redemption or purchase of
redeemable shares.

          5.  Voting Rights.  Except for those purposes only for which the right
              -------------                                                     
to vote is expressly conferred in this Article VI upon holders of the Preferred
Stock, no holders of the Preferred Stock shall be entitled to notice of or to
vote at any meeting of shareholders of the Corporation or at any election of the
Corporation or the shareholders thereof.

          If and when dividends payable on any of the Preferred Stock shall be
in default in an amount equal to six full quarterly payments or more per share,
and thereafter until all dividends on any of the Preferred Stock in default
shall have been paid, the holders of all of the Preferred Stock, voting as a
class in contradistinction to the Common Stock as a class, shall be entitled to
elect the smallest number of directors necessary to constitute a majority of the
full Board of Directors, and the holders of the Common Stock, voting separately
as a class, shall be entitled to elect the remaining directors of the
Corporation.  The terms of office as directors of all persons who may be
directors of the Corporation at the time shall terminate upon the election of a
majority of the Board of Directors by the holders of the Preferred Stock, except
that if the holders of the Common Stock shall not have elected the remaining
directors of the Corporation then, and only in that event, the directors of the
Corporation in office just prior to the election of a majority of the Board of
Directors by the holders of the Preferred Stock shall elect the remaining
directors to the Corporation.  Thereafter, while such default continues and the
majority of the Board is being elected by the holders of the Preferred Stock,
the remaining directors, whether elected by directors, as aforesaid, or whether
originally or later elected by holders of the Common Stock, shall continue in
office until their successors are elected by holders of the Common Stock and
shall qualify.  The term of office of the directors so elected by the holders of
the Preferred Stock, voting separately as a class, and of the directors elected
by the holders of the Common Stock, voting separately as a class, or elected by
directors, as aforesaid, shall be until the next annual meeting of shareholders
or until the privilege of the holders of the Preferred Stock to elect directors
shall terminate as hereinafter provided, whichever shall be the earlier date and
until their successors shall have been elected and shall have qualified.

          If and when all dividends then in default on all of the Preferred
Stock shall be paid (such dividends to be declared and paid out of any funds
legally available therefor as soon as reasonably practicable), the holders of
the Preferred Stock shall be divested of any privilege with respect to the
election of directors which is conferred upon the holders of such Preferred
Stock under this Section 5, and the voting power of the holders of the Preferred
Stock and the holders of the Common Stock shall revert to the status existing
before the first dividend payment date on which dividends on any of the
Preferred Stock were not paid in full, but always subject to the same provisions
for vesting such privilege in the holders of the Preferred Stock in case of
further like default or defaults in the payment of dividends thereon.  Upon
termination of any such voting privilege upon payment of all accumulated and
defaulted dividends on the Preferred Stock, the terms of office of all persons
who have been elected directors of the Corporation by vote of the holders of the
Preferred Stock as a class, pursuant to such voting privilege, shall forthwith
terminate, and the resulting vacancies shall be filled by the vote of a majority
of the remaining directors.

          In case of any vacancy in the office of a director occurring among the
directors elected by the holders of the Preferred Stock, voting as a class, the
remaining directors elected by the holders of the Preferred Stock, by
affirmative vote of a majority thereof, or the remaining director so elected if
there be but one, may elect a successor or successors to hold office for the
unexpired term or terms of the director or directors whose place or places shall
be vacant.  In case of any vacancy in the office of a director occurring among
the directors elected by the holders of the Common Stock, voting 

                                       8
<PAGE>
 
separately as a class, or elected by directors, as aforesaid, the remaining
directors so elected, by affirmative vote of a majority thereof, or the
remaining director so elected if there be but one, may elect a successor or
successors to hold office for the unexpired term or terms of the director or
directors whose place or places shall be vacant.

          Whenever dividends on the Preferred Stock shall be in default, as
provided in this Section 5, it shall be the duty of the officers of  the
Corporation, or in the event of their failure to do so within twenty (20) days
of such default, the privilege is granted any holder of Preferred Stock who
shall first demand the right so to do by written notice to the Corporation,
forthwith to cause notice to be given to the holders of the Preferred Stock and
to the holders of the Common Stock of a meeting to be held at such time as the
Corporation's officers, or such holder of Preferred Stock, as the case may be,
may fix, not less than ten (10) nor more than sixty (60) days after the accrual
of such privilege, for the purpose of electing directors.  Each holder of record
of Preferred Stock, or his legal representative, shall be entitled at such
meeting to one vote for each share of Preferred Stock standing in his name on
the books of the Corporation.  At each meeting of shareholders held for such
purpose, the presence in person or by proxy of the holders of a majority of the
Common Stock shall be required to constitute a quorum of the Common Stock for
the election of directors, and the presence in person or by proxy of the holders
of a majority of the Preferred Stock shall be required to constitute a quorum of
the Preferred Stock for the election of directors; provided, however, that the
absence of a quorum of the holders of stock of either the Preferred Stock or the
Common Stock shall not prevent the election at any such meeting or adjournment
thereof of directors by such other class, if the necessary quorum of the holders
of stock of such other class is present in person or by proxy at such meeting or
any adjournment thereof, and provided, that in the event a quorum of the holders
of the Common Stock is present but a quorum of the holders of the Preferred
Stock is not present, then the directors so elected by the holders of the Common
Stock shall not assume their offices and duties but the directors in office
immediately prior thereto shall remain in office until the holders of the
Preferred Stock, with a quorum present, shall have elected the directors they
shall be entitled to elect; and provided, further, that in the absence of a
quorum of holders of stock of either class, a majority of the holders of the
stock of the class which lacks a quorum who are present in person or by proxy,
shall have power to adjourn the election of the directors to be elected by such
class from time to time without notice other than announcement at the meeting,
until the requisite quorum of holders of such class shall be present in person
or by proxy, but such adjournment shall not be made to a date beyond the date
for the mailing of the notice of the next annual meeting of shareholders of the
Corporation or special meeting in lieu thereof.

          6.  Restrictions on Certain Corporate Action.
              ---------------------------------------- 

          (a)  So long as any shares of the Preferred Stock are outstanding, the
Corporation shall not, without the consent (given by vote at a meeting called
for that purpose) of the holders of at least a majority of the total number of
shares of the Preferred Stock then outstanding:

                  (1) Create or authorize any new stock ranking prior to the
Preferred Stock as to dividends or in liquidation, dissolution, winding up or
distribution, or create or authorize any security convertible into shares of any
such stock; or

                  (2) Amend, alter, change or repeal any of the express terms of
the Preferred Stock then outstanding in a manner substantially prejudicial to
the holders thereof, provided however, that if such amendment, alteration, or
change affects less than all series of Preferred Stock, 

                                       9
<PAGE>
 
only the consent of the holders of a majority of the aggregate of the series so
affected shall be required.

          (b)  So long as any shares of the Preferred Stock are outstanding, the
Corporation shall not, without the consent (given by vote at a meeting called
for that purpose) of the holders of a majority of the total number of shares of
the Preferred Stock, considered as one class, then outstanding:

                  (1) Create or assume any unsecured indebtedness maturing more
than one year after the date of its creation or assumption unless and until the
Corporation's net earnings available for the payment of interest (gross
operating revenues plus other income, minus operating expenses, including
depreciation expense and taxes, other than income, profits, and other taxes,
measured by, or dependent on, income) as determined by generally accepted
accounting practices and as stated on the books of account of the Corporation
for a period of twelve consecutive calendar months ending not more than three
months prior to the beginning of the calendar month in which such indebtedness
shall be created or assumed, shall have been at least twice the interest charges
(using, for the purpose of this computation with respect to indebtedness with
interest rates that are not fixed, the interest rate in effect at the end of
such twelve month period) on all outstanding indebtedness created or assumed by
the Corporation and payable more than one year from the date of such creation or
assumption, including the interest charges on the indebtedness so to be created
or assumed (using, for the purpose of this computation, the interest rate in
effect at the time of incurrence or assumption of such indebtedness); provided
that the requirements of this subparagraph (1) shall not apply to indebtedness
created or assumed to refund by payment, replacement, retirement, acquisition,
purchase, exchange, redemption, surrender or otherwise all outstanding shares of
the Preferred Stock or any indebtedness outstanding at any time and maturing
more than one year after the date of creation or assumption of such refunded
indebtedness; or

                  (2) Issue, sell or dispose of any shares of the Preferred
Stock in addition to the shares of Preferred Stock outstanding, or of any other
class of stock ranking prior to, or on a parity with, the Preferred Stock as to
dividends or distributions, unless the net income of the Corporation, determined
after provisions for depreciation and all taxes, and in accordance with
generally accepted accounting principles to be available for the payment of
dividends for a period of twelve (12) consecutive calendar months within the
fifteen (15) calendar months immediately preceding the issuance, sale or
disposition of such stock is at least equal to twice the annual dividend
requirements on all outstanding shares of the Preferred Stock and of all other
classes of stock ranking prior to, or on a parity with, the Preferred Stock as
to dividends or distributions, including the shares proposed to be issued;
provided that there shall be excluded from the foregoing computation interest
charges on all indebtedness and dividends on all stock which is to be retired in
connection with the issue of such additional shares of Preferred Stock, and
where such additional shares of Preferred Stock are to be issued in connection
with the acquisition of new property, the net earnings of the property to be so
acquired may be included on a pro forma basis in the foregoing computation,
computed on the same basis as the net earnings of the Corporation; or

                  (3) Pay any dividend on any stock of the Corporation junior to
the Preferred Stock if immediately after such payment the retained earnings of
the Corporation would be less than one and one-half (1-1/2) times the full

          miscellaneous non-operating sources, and excluding any extraordinary

          principles, any regulatory disallowances, the effect of any change in

          of (2), (3) and (4) from the amount of item (1) above, shall be the
          "net earnings available for the payment of interest" for the purposes
          of this Section 6.

          For purposes of this Section 6, the term "indebtedness" shall not

               -------------------------------------------------------- 

884,700 shares of the authorized stock classified as Preferred Stock as provided
in Division A of this Article VI shall constitute the thirty-third series of
Preferred Stock and are designated as Adjustable Rate Cumulative Preferred
Stock, Series A, which series shall have, in addition to the general terms and
characteristics of all the authorized shares of Preferred Stock of the
Corporation, the following distinctive terms and characteristics:      (a) The
thirty-third series of Preferred Stock shall have a dividend rate for the
initial dividend payment period ending July 31, 1984, at the rate of 11.04% per
annum, and for each subsequent quarterly dividend period at the Applicable Rate
(as hereinafter defined) from time to time in effect, provided that the dividend
rate on the thirty-third series of Preferred Stock for any dividend period shall
in no event be less than 6.50% per annum or 

                                       14
<PAGE>
 
greater than 13% per annum. Except as provided below in this paragraph, the
"Applicable Rate" for any dividend period will be 2.50% less than the highest of
(i) the Treasury Bill Rate, (ii) the Ten Year Constant Maturity Rate and (iii)
the Twenty Year Constant Maturity Rate (each as hereinafter defined) for such
dividend period. In the event that the Corporation determines in good faith that
for any reason one or more of such rates cannot be determined for any dividend
period, then the Applicable Rate for such dividend period shall be 2.50% less
than the higher of whichever of such rates can be so determined. In the event
that the Corporation determines in good faith that none of such rates can be
determined for any dividend period, then the Applicable Rate in effect for the
preceding dividend period shall be continued for such dividend period.

          Except as provided below in this paragraph, the "Treasury Bill Rate"
for each dividend period will be the arithmetic average of the two most recent
weekly per annum secondary market discount rates (or the one weekly per annum
secondary market discount rate, if only one such rate shall be published  during
the relevant Calendar Period  (as defined below))  for three-month U. S.
Treasury bills, as published weekly by the Federal Reserve Board during the
Calendar Period immediately prior to the last ten calendar days of July,
October, January or April, as the case may be, prior to the dividend period for
which the Applicable Rate is being determined.  In the event that the Federal
Reserve Board does not publish such a weekly per annum secondary market discount
rate during any such Calendar Period, then the Treasury Bill Rate for such
dividend period shall be the arithmetic average of the two most recent weekly
per annum secondary market discount rates (or the one weekly per annum secondary
market discount rate, if only one such rate shall be published during such
Calendar Period) for the three-month U. S. Treasury bills, as published weekly
during such Calendar Period by any Federal Reserve Bank or by any U. S.
Government department or agency selected by the Corporation.  In the event that
a per annum secondary market discount rate for three-month U. S. Treasury bills
shall not be published by the Federal Reserve Board or by any Federal Reserve
Bank or by any U. S. Government department or agency during such Calendar
Period, then the Treasury Bill Rate for such dividend period shall be the
arithmetic average of the two most recent weekly per annum secondary market
discount rates (or the one weekly per annum secondary market discount rate, if
only one such rate shall be published during such Calendar Period) for all of
the U. S. Treasury bills then having maturities of not less than 80 nor more
than 100 days, as published during such Calendar Period by the Federal Reserve
Board or, if the Federal Reserve Board shall not publish such rates, by any
Federal Reserve Bank or by any U. S. Government department or agency selected by
the Corporation.  In the event that the Corporation determines in good faith
that for any reason no such U. S. Treasury bill rates are published as provided
above during such Calendar Period, then the Treasury Bill Rate for such dividend
period shall be the arithmetic average of the per annum secondary market
discount rates based upon the closing bids during such Calendar Period for each
of the issues of marketable non-interest bearing U. S. Treasury securities with
a maturity of not 

                                       15
<PAGE>
 
less than 80 nor more than 100 days from the date of each such quotation, as
quoted daily for each business day in New York City (or less frequently if daily
quotations shall not be generally available) to the Corporation by at least
three recognized U. S. Government securities dealers selected by the
Corporation.

          Except as provided below in this paragraph, the "Ten Year Constant
Maturity Rate" for each such dividend period shall be the arithmetic average of
the two most recent weekly per annum Ten Year Average Yields (as defined below)
(or the one weekly per annum Ten Year Average Yield, if only one such Yield
shall be published during the relevant Calendar Period as provided below), as
published weekly by the Federal Reserve Board during the Calendar Period
immediately prior to the last ten calendar days of July, October, January or
April, as the case may be, prior to the dividend period for which the Applicable
Rate is being determined.  In the event that the Federal Reserve Board does not
publish such a weekly per annum Ten Year Average Yield during such Calendar
Period, then the Ten Year Constant Maturity Rate for such dividend period shall
be the arithmetic average of the two most recent weekly per annum Ten Year
Average Yields, (or the one weekly per annum Ten Year Average Yield, if only one
such yield shall be published during such Calendar Period), as published weekly
during such Calendar Period by any Federal Reserve Bank or by any U. S.
Government department or agency selected by the Corporation.  In the event that
a per annum Ten Year Average Yield shall not be published by the Federal Reserve
Board or by any Federal Reserve Bank or by any U. S. Government department or
agency during such Calendar Period, then the Ten Year Constant Maturity Rate for
such dividend period shall be the arithmetic average of the two most recent
weekly per annum average yields to maturity (or the one weekly average yield to
maturity, if only one such yield shall be published during such Calendar Period)
for all of the actively traded marketable U. S. Treasury fixed interest rate
securities (other than Special Securities, as defined below) then having
maturities of not less than eight nor more than twelve years, as published
during such Calendar Period by the Federal Reserve Board or, if the Federal
Reserve Board shall not publish such yields, by any Federal Reserve Bank or by
any U. S. Government department or agency selected by the Corporation.  In the
event that the Corporation determines in good faith that for any reason the
Corporation cannot determine the Ten Year Constant Maturity Rate for any
dividend period as provided above in this paragraph, then the Ten Year Constant
Maturity Rate for such dividend period shall be the arithmetic average of the
per annum average yields to maturity based upon the closing bids during such
Calendar Period for each of the issues of actively traded marketable U. S.
Treasury fixed interest rate securities (other than Special Securities) with a
final maturity date not less than eight nor more than twelve years from the date
of each such quotation, as quoted daily for each business day in New York City
(or less frequently if daily quotations shall not be generally available) to the
Corporation by at least three recognized U. S. Government securities dealers
selected by the Corporation.

          Except as provided below in this paragraph, the "Twenty Year Constant
Maturity Rate" for each such dividend period shall be the arithmetic average of
the two most recent weekly per annum Twenty Year Average Yields (as defined
below) (or the one weekly per annum Twenty Year Average Yield, if only one such
Yield shall be published during the relevant Calendar Period), as published
weekly by the Federal Reserve Board during the Calendar Period immediately prior
to the last ten calendar days of July, October, January or April, as the case
may be, prior to the dividend period for which the Applicable Rate is being
determined.  In the event that the Federal Reserve Board does not publish such a
weekly per annum Twenty Year Average Yield during such Calendar 

                                       16
<PAGE>
 
Period, then the Twenty Year Constant Maturity Rate for such dividend period
shall be the arithmetic average of the two most recent weekly per annum Twenty
Year Average Yields (or the one weekly per annum Twenty Year Average Yield, if
only one such Yield shall be published during such Calendar Period), as
published weekly during such Calendar Period by any Federal Reserve Bank or by
any U. S. Government department or agency selected by the Corporation. In the
event that a per annum Twenty Year Average Yield shall not be published by the
Federal Reserve Board or by any Federal Reserve Bank or by any U. S. Government
department or agency during such Calendar Period, then the Twenty Year Constant
Maturity Rate for such dividend period shall be the arithmetic average of the
two most recent weekly per annum average yields to maturity (or the one weekly
average yield to maturity, if only one such yield shall be published during such
Calendar Period) for all of the actively traded marketable U. S. Treasury fixed
interest rate securities (other than Special Securities) then having maturities
of not less than eighteen nor more than twenty-two years, as published during
such Calendar Period by the Federal Reserve Board or, if the Federal Reserve
Board shall not publish such yields, by any Federal Reserve Bank or by any U. S.
Government department or agency selected by the Corporation. In the event that
the Corporation determines in good faith that for any reason the Corporation
cannot determine the Twenty Year Constant Maturity Rate for any dividend period
as provided above in this paragraph, then the Twenty Year Constant Maturity Rate
for such dividend period shall be the arithmetic average of the per annum
average yields to maturity based upon the closing bids during such Calendar
Period for each of the issues of actively traded marketable U. S. Treasury fixed
interest rate securities (other than Special Securities) with a final maturity
date not less than eighteen nor more than twenty-two years from the date of each
such quotation, as quoted daily for each business day in New York City (or less
frequently if daily quotations shall not be generally available) to the
Corporation by at least three recognized U. S. Government securities dealers
selected by the Corporation.

          The Treasury Bill Rate, the Ten Year Constant Maturity Rate and the
Twenty Year Constant Maturity Rate shall each be rounded to the nearest five
one-hundredths of a percentage point.

          The amount of dividends per share payable for each dividend period
shall be computed by dividing the Applicable Rate for such period by four and
applying the rate derived from such division against the fixed liquidation price
of $100 per share of the thirty-third series.  The amount of dividends payable
for any period shorter than a full quarterly dividend period and for the initial
dividend period shall be computed on the basis of a 360-day year of 30-day
months and the actual number of days which have elapsed in such period.

          The Applicable Rate with respect to each dividend period will be
calculated as promptly as practicable by the Corporation according to the
appropriate method described herein. The mathematical accuracy of each such
calculation will be confirmed in writing by independent accountants of
recognized standing.  The Corporation will cause each dividend rate to be
published in a newspaper of general circulation in New York City prior to the
commencement of the new dividend period to which it applies and will cause
notice of such Applicable Rate to be mailed to the holders of the thirty-third
series.

          As used herein, the term "Calendar Period" means a period of fourteen
calendar days; the term "Special Securities" means securities which can, at the
option of the holder, be surrendered at face value in payment of any Federal
estate tax or which provide tax benefits to the holder and are priced to reflect
such tax benefits or which were originally issued at a deep or substantial
discount; 

                                       17
<PAGE>
 
the term "Ten Year Average Yield" means the average yield to maturity for
actively traded marketable U. S. Treasury fixed interest rate securities
(adjusted to constant maturities of ten years); and the term "Twenty Year
Average Yield" means the average yield to maturity for actively traded
marketable U. S. Treasury fixed interest rate securities (adjusted to constant
maturities of twenty years).

          (b)  Said thirty-third series shall not be redeemable prior to June 1,

rights shall be exercised may be limited by the Board of Directors to such time
as the said Board may deem proper, not less, however, than twenty days after

The foregoing provisions of this paragraph shall not be changed unless the
holders of record of not less than two-thirds (2/3) of the number of shares of
Common Stock then outstanding shall consent thereto in writing or by voting
therefor in person or by proxy at the meeting of stockholders at which any such
change is considered.

provided, shall be entitled to one vote for each share of stock held by him.

          The Corporation from time to time, subject to the limitations or
requirements hereinabove provided and to the extent it may lawfully do so, may

                                 ARTICLE VIII
                                 ------------

          Subject to the other provisions hereof, in order to acquire funds with
which to make any redemption or purchase of stock herein authorized, the

to the extent it may lawfully do so, may issue and sell Common Stock or

                                  ARTICLE IX
                                  ----------

          The Corporation shall reimburse or indemnify any former, present or
future director, officer or employee of the Corporation, or any person who may
have served at its request as a director, officer or employee of another
corporation, or any former, present or future director, officer or employee of
the Corporation who shall have served or shall be serving as an administrator,
agent or fiduciary for the Corporation or for another corporation at the request
of the Corporation (and his heirs, executors and administrators) from and
against all expenses and liabilities incurred by him or them, or imposed on him
or them, including, but not limited to, judgments, settlements, court costs and
attorneys' fees, in connection with, or arising out of, the defense of any
action, suit or proceeding in which he may be involved by reason of his being or
having been such director, officer or employee, except with respect to matters
as to which he shall be adjudged in such action, suit or proceeding to be liable
because he did not act in good faith, or because of dishonesty or conflict of
interest in the performance of his duty.

          No former, present or future director, officer or employee of the
Corporation (or his heirs, executors and administrators) shall be liable for any
act, omission, step or conduct taken or had in good faith, which is required,
authorized or approved by any order or orders issued pursuant to the Public
Utility Holding Company Act of 1935, the Federal Power Act, or any other federal
or state statute regulating the Corporation or its subsidiaries, or any
amendments to any thereof.  In any action, suit or proceeding based on any act,
omission, step or conduct, as in this paragraph described, the provisions hereof
shall be brought to the attention of the court.  In the event that the foregoing
provisions of this paragraph are found by the court not to constitute a valid
defense, each such

<PAGE>
 
director, officer or employee (and his heirs, executors and administrators)
shall be reimbursed for, or indemnified against, all expenses and liabilities
incurred by him or them, or imposed on him or them, including, but not limited
to, judgments, settlements, court costs and attorneys' fees, in connection with,
or arising out of, any such action, suit or proceeding based on any act,
omission, step or conduct taken or had in good faith as in this paragraph
described.

          The foregoing rights shall not be exclusive of other rights to which
any such director, officer or employee (or his heirs, executors and
administrators) may otherwise be entitled under any bylaw, agreement, vote of
shareholders or otherwise, and shall be available whether or not the director,
officer or employee continues to be a director, officer or employee at the time
of incurring such expenses and liabilities.  In furtherance, and not in
limitation of the foregoing provisions of this Article IX, the Corporation may
indemnify and insure any such persons to the fullest extent permitted by the
Texas Business Corporation Act, as amended from time to time, or the laws of the
State of Texas, as in effect from time to time.

                                   ARTICLE X
                                   ---------

          A director of the Corporation shall not be liable to the Corporation
or its shareholders for monetary damages for any act or omission in the
director's capacity as a director, except that this provision does not eliminate
or limit liability of a director for:

          (a)  a breach of a director's duty of loyalty to the Corporation or
          its shareholders;

          (b)  an act or omission not in good faith that constitutes a breach of
          duty of a director to the Corporation or an act or omission that
          involved intentional misconduct or a knowing violation of the law;

          (c)  a transaction from which a director received an improper benefit,
          whether or not the benefit resulted from an action taken within the
          scope of the director's office; or

          (d)  an act or omission for which the liability of a director is
          expressly provided for by statute.

          If the laws of the State of Texas are amended to authorize action
further eliminating or limiting the personal liability of directors, then the
liability of a director of the Corporation shall be eliminated or limited to the
fullest extent permitted by such laws as so amended.  Any repeal or modification
of this Article X shall not adversely affect any right of protection of a
director of the Corporation existing at the time of such repeal or modification.

                                  ARTICLE XI
                                  ----------

          The power to alter, amend or repeal the Bylaws of the Corporation, or
to adopt new Bylaws, is hereby delegated to the Board of Directors subject to
repeal or change by action of the shareholders.

                                  ARTICLE XII
                                  -----------

          The Corporation has heretofore complied with the requirements of law
as to the initial minimum capital requirements without which it could not
commence business under the Texas Business Corporation Act.

                          NINETY-FIFTH SERIES OF BONDS

     SECTION 1.  There shall be a series of bonds designated "Pollution Control
Series AH" (herein sometimes referred to as the "Ninety-fifth Series"), each of
which shall also bear the descriptive title "First Mortgage Bond", and the form
thereof, which shall be established in accordance with a Resolution of the Board
of Directors of the Company, shall contain suitable provisions with respect to
the matters hereinafter in this Section specified.  Bonds of the Ninety-fifth
Series may be issued in one or more tranches and may be issued with up to one

option of the Company, in any multiple or multiples thereof (the exercise of
such option 
<PAGE>
 
                                       9

to be evidenced by the execution and delivery thereof); Bonds of the
Ninety-fifth Series shall mature on such date not later than the maturity date
of the Series 1997D Brazos Revenue Bonds, referred to below, shall bear interest
at such rate or rates, payable on such date or dates, and have such other terms
and provisions not inconsistent with the Original Indenture as the proper
officer or officers of the Company may determine in accordance with one or more
Resolutions filed with the Trustee referring to this Fifty-eighth Supplemental
Indenture (such determinations shall be evidenced by or in accordance with one
or more written orders filed with the Trustee for the authentication and
delivery of bonds of the Ninety-fifth Series and shall constitute determinations
of the Board of Directors with respect to such bonds for purposes of the
Mortgage), the principal of each said bond to be payable at the office or agency
of the Company in the Borough of Manhattan, The City of New York, New York, or
at the office or agency of the Company in the City of Dallas, Texas, as the
holder of any said bond may elect, in such coin or currency of the United States
of America as at the time of payment is legal tender for public and private
debts.  Bonds of the Ninety-fifth Series shall be dated as in Section 2.03 of
the Original Indenture provided.

     (I)  The bonds of the Ninety-fifth Series shall be initially issued in an
aggregate principal amount not to exceed $33,079,750 to, and registered in the
name of, the trustee under the Trust Indenture, dated as of July 1, 1997
(hereinafter sometimes called the "1997D Brazos Bond Indenture"), of the Brazos
River Authority (hereinafter sometimes called the "Brazos Authority"), under
which its Collateralized Pollution Control Revenue Refunding Bonds (Texas
Utilities Electric Company Project) Series 1997D (hereinafter sometimes called
the "Series 1997D Brazos Revenue Bonds") are to be issued, in order to provide
the benefit of a lien to secure the obligation of the Company to make the
Installment Payments and Purchase Price payments pursuant to, and as such terms
are defined in, the Series 1997D Installment Sale and Bond Amortization
Agreement, dated as of July 1, 1997 (hereinafter sometimes called the "1997D
Brazos Agreement"), between the Brazos Authority and the Company.  The maximum
amount of bonds of the Ninety-fifth Series that may be issued is unlimited but
the aggregate principal amount of bonds of the Ninety-fifth Series at any one
time Outstanding shall not exceed $33,079,750.  The maximum stated interest rate
for any bonds of the Ninety-fifth Series shall not exceed 15% per annum.

     The Company shall receive a credit against its obligation to make any
payment of the principal of and interest, if any, on any tranche of the bonds of
the Ninety-fifth Series, whether at maturity, upon redemption or otherwise, in
an amount equal to (x) the sum of (a) the amount, if any, on deposit in the Debt
Service Fund maintained under the 1997D Brazos Bond Indenture which reduces the
corresponding Installment Payment and (b) the amount, if any, paid by the
Company pursuant to Section 5.04 of the 1997D Brazos Agreement in respect of the
corresponding Installment Payment multiplied by (y) the ratio of the principal
amount of Outstanding bonds of the Ninety-fifth Series to the principal amount
of outstanding Series 1997D Brazos Revenue Bonds.

     The Trustee may conclusively presume that the obligation of the Company to
pay the principal of, and interest, if any, on any tranche of the bonds of the
Ninety-fifth Series 
<PAGE>
 
                                       10

as the same shall become due and payable shall have been fully satisfied and
discharged unless and until it shall have received a written notice from the
trustee under the 1997D Brazos Bond Indenture, signed by the President, a Vice
President or a Trust Officer of such trustee, stating that the corresponding
Installment Payment or Purchase Price payment has become due and payable and has
not been fully paid and specifying the amount of funds required to make such
payment.

     (II)  In the event that any Series 1997D Brazos Revenue Bonds outstanding
under the 1997D Brazos Bond Indenture shall become immediately due and payable
pursuant to Section 6.02 of the 1997D Brazos Bond Indenture, upon the occurrence
of an Event of Default under Section 6.01(a) of the 1997D Brazos Bond Indenture,
all bonds of the Ninety-fifth Series, then Outstanding, shall be redeemed by the
Company, on the date such Series 1997D Brazos Revenue Bonds shall have become
immediately due and payable, at the principal amount thereof.

     The Trustee may conclusively presume that no redemption of bonds of the
Ninety-fifth Series is required pursuant to the first paragraph of this
subsection (II) unless and until it shall have received a written notice from
the trustee under the 1997D Brazos Bond Indenture, signed by the President, a
Vice President or a Trust Officer of such trustee, stating that Series 1997D
Brazos Revenue Bonds have become immediately due and payable pursuant to Section
6.02 of the 1997D Brazos Bond Indenture, upon the occurrence of an Event of
Default under Section 6.01(a) of the 1997D Brazos Bond Indenture and specifying
the principal amount thereof.  Said notice shall also contain a waiver of notice
of such redemption by the trustee under the 1997D Brazos Bond Indenture, as the
holder of all bonds of the Ninety-fifth Series then Outstanding.

     (III)  The Company hereby waives its right to have any notice of redemption
pursuant to subsection (II) of this Section 1 state that such notice is subject
to the receipt of the redemption moneys by the Trustee on or before the date
fixed for redemption. Notwithstanding the provisions of Section 12.02 of the
Mortgage, any such notice under such subsection shall not be conditional.

     (IV)  At the option of the registered owner, any bonds of the Ninety-fifth
Series, upon surrender thereof for cancellation at the office or agency of the
Company in the Borough of Manhattan, The City of New York, New York, shall be
exchangeable for a like aggregate principal amount of bonds of the same series
of other authorized denominations.

     Bonds of the Ninety-fifth Series shall not be transferrable except to any
successor trustee under the 1997D Brazos Bond Indenture, any such transfer to be
made at the office or agency of the Company in the Borough of Manhattan, The
City of New York, New York.

     The Company hereby waives any right to make a charge for any exchange or
transfer of bonds of the Ninety-fifth Series.

month's accrued interest.  Bonds of the Ninety-sixth Series shall be issued as
fully registered bonds in denominations of One Hundred Dollars and, at the
option of the Company, in any multiple or multiples thereof (the exercise of
such option to be evidenced by the execution and delivery thereof); Bonds of the
Ninety-sixth Series shall mature on such date not later than the maturity date
of the Series 1997A Sabine Revenue Bonds, referred to below, shall bear interest
at such rate or rates, payable on such date or dates, and have such other terms
and provisions not inconsistent with the Original Indenture as the proper
officer or officers of the Company may determine in accordance with one or more
Resolutions filed with the Trustee referring to this Fifty-eighth Supplemental
Indenture (such determinations shall be evidenced by or in accordance with one
or more written orders filed with the Trustee for the authentication and
delivery of bonds of the Ninety-sixth Series and shall constitute determinations
of the Board of Directors with respect to such bonds for purposes of the
Mortgage), the principal of each said bond to be payable at the office or agency
of the Company in the Borough of Manhattan, The City of New York, New York, or
at the office or agency of the Company in the City of Dallas, Texas, as the

maximum stated interest rate for any bonds of the Ninety-sixth Series shall not
exceed 15% per annum.

     The Company shall receive a credit against its obligation to make any
payment of the principal of and interest, if any, on any tranche of the bonds of

an amount equal to (x) the sum of (a) the amount, if any, on deposit in the Debt
Service Fund maintained under the 1997A Sabine Bond Indenture which reduces the
corresponding Installment Payment and (b) the amount, if any, paid by the
Company pursuant to Section 5.04 of the 1997A Sabine Agreement in respect of the
corresponding Installment Payment multiplied by (y) the ratio of the principal
amount of Outstanding bonds of the Ninety-sixth Series to the principal amount
of outstanding Series 1997A Sabine Revenue Bonds.

     The Trustee may conclusively presume that the obligation of the Company to
pay the principal of, and interest, if any, on any tranche of the bonds of the
Ninety-sixth Series as the same shall become due and payable shall have been
fully satisfied and discharged unless and until it shall have received a written
notice from the trustee under the 1997A Sabine Bond Indenture, signed by the
President, a Vice President or a Trust Officer of such trustee, stating that the
corresponding Installment Payment or Purchase Price payment has become due and
payable and has not been fully paid and specifying the amount of funds required
to make such payment.

under the 1997A Sabine Bond Indenture shall become immediately due and payable
pursuant to Section 6.02 of the 1997A Sabine Bond Indenture, upon the occurrence
of an Event of Default under Section 6.01(a) of the 1997A Sabine Bond Indenture,
all bonds of the Ninety-sixth Series, then Outstanding, shall be redeemed by the
Company, on the date such Series 1997A Sabine Revenue Bonds shall have become
immediately due and payable, at the principal amount thereof.

     The Trustee may conclusively presume that no redemption of bonds of the
Ninety-sixth Series is required pursuant to the first paragraph of this
subsection (II) unless and until it shall have received a written notice from
the trustee under the 1997A Sabine Bond Indenture, signed by the President, a
Vice President or a Trust Officer of such trustee, stating that Series 1997A
Sabine Revenue Bonds have become immediately due and payable pursuant to Section
6.02 of the 1997A Sabine Bond Indenture, upon the occurrence of an Event of

the principal amount thereof.  Said notice shall also contain a waiver of notice
of such redemption by the trustee under the 1997A Sabine Bond Indenture, as the
holder of all bonds of the Ninety-sixth Series then Outstanding.

     (III)  The Company hereby waives its right to have any notice of redemption
pursuant to subsection (II) of this Section 2 state that such notice is subject
to the receipt of the redemption moneys by the Trustee on or before the date
fixed for redemption. Notwithstanding the provisions of Section 12.02 of the

notice from the trustee under the 1997A Trinity Bond Indenture, signed by the

Said notice shall also contain a waiver of notice of such redemption by the
trustee under the 1997A Trinity Bond Indenture, as the holder of all bonds of

pursuant to subsection (II) of this Section 3 state that such notice is subject
to the receipt of the redemption moneys by the Trustee on or before the date
fixed for redemption. Notwithstanding the provisions of Section 12.02 of the

the Company or Subsidiary which employs him or her, may be based on the division
or business unit which employs him or her, may be based on the performance of
the Company and its Subsidiaries generally, or any combination of the foregoing.

Committee may, at any time and from time to time, award shares of Bonus Stock to
participants under the Plan without cash consideration.  The Committee shall
determine and indicate in the related Award Agreement whether such shares of
Bonus Stock shall be unencumbered of any restrictions (other than those which
the Committee deems necessary or advisable to comply with law) or shall be
subject to restrictions and limitations similar to those referred to in Section
9.  In the event the Committee assigns any restrictions on the shares of Bonus
Stock, then such shares shall be subject to at least the following restrictions:

     (a)       No Shares of Bonus Stock may be sold, transferred, pledged,
               assigned or otherwise alienated or hypothecated if such Shares
               are subject to restrictions which have not lapsed or been
               satisfied.

     (b)       If any condition of vesting of the shares of Bonus Stock are not
               met, all such Shares subject to such vesting shall be delivered
               to the Company (in a manner determined by the Committee) within

               ---------------------------------                           
provisions of the Plan and applicable law, the Committee may, at any time and
from time to time, issue to Participants, either alone or in addition to other
Awards made under the Plan, Stock Unit Awards which may be in the form of Common
Stock or other securities.  The value of each such Award shall be based, in
whole or in part, on the value of the underlying Common Stock on the Grant Date.
The Committee, in its sole and complete discretion, may determine that an Award,
either in the form of a Stock Unit Award under this Section 11 or as an Award
granted pursuant to Sections 6 through 10, may provide to the Participant (i)
dividends or dividend equivalents (payable on a current or deferred basis) and
(ii) cash payments in lieu of or in addition to an Award.  Subject to the
provisions of the Plan, the Committee, in its sole and complete discretion,
shall determine the terms, restrictions, conditions, vesting requirements, and
payment rules of the Award.  The Award Agreement shall specify the rules of each
Award as determined by the Committee.  However, each Stock Unit Award need not
be subject to identical rules.

     11.2      Rules.  The Committee, in its sole and complete discretion, may 
               -----
grant a Stock Unit Award subject to the following rules:

                                       12
<PAGE>
 
     (a)       Common Stock or other securities issued pursuant to Stock Unit
               Awards may not be sold, transferred, pledged, assigned or
               otherwise alienated or hypothecated by a Participant until the
               expiration of at least six months from the Grant Date, except
               that such limitation shall not apply in the case of death or
               Disability of the Participant or a Change in Control. To the
               extent Stock Unit Awards are deemed to be derivative securities
               within the meaning of Rule 16b-3, the rights of a Participant who
               is subject to Section 16 of the Exchange Act with respect to such
               Awards shall not vest or be exercisable until the expiration of
               at least six months from the Award Date. All rights with respect
               to such Stock Unit Awards granted to a Participant under the Plan
               shall be exercisable during his or her lifetime only by such
               Participant or his or her guardian or legal representative.

     (b)       Stock Unit Awards may require the payment of cash consideration
               by the Participant in receipt of the Award or provide that the
               Award, and any Common Stock or other securities issued in
               conjunction with the Award, be delivered without the payment of
               cash consideration.

     (c)       The Committee, in its sole and complete discretion, may establish
               certain Performance Criteria that may relate in whole or in part
               to receipt of Stock Unit Awards.

     (d)       Stock Unit Awards may be subject to a deferred payment schedule
               and/or vesting over a specified period.

     (e)       The Committee, in its sole and complete discretion, as a result
               of certain circumstances, may waive or otherwise remove, in whole
               or in part, any restriction or condition imposed on a Stock Unit
               Award.

SECTION 12.    SPECIAL PROVISIONS APPLICABLE TO COVERED PARTICIPANTS

     Awards to Covered Participants shall be governed by the conditions of this
Section 12 in addition to the requirements of Sections 6 through 11 above.
Should conditions set forth under this Section 12 conflict with the requirements
of Sections 6 through 11, the conditions of this Section 12 shall prevail.

     (a)       All Performance Criteria relating to Covered Participants for a
               relevant Performance Period shall be established by the Committee
               in writing prior to the beginning of the Performance Period, or
               by such other later date for the Performance Period as may be
               permitted under Section 162(m) of the Code. Performance Criteria
               may include alternative and multiple Performance Criteria and
               will be based on one or more of the following business criteria:
               business or financial goals of the Company, including absolute or
               relative levels of total shareholder return, revenues, sales, net
               income, or net worth of the Company, any of its Subsidiaries,
               divisions, business units, or other areas of the Company.

                                       13
<PAGE>
 
     (b)       The Performance Criteria must be objective and must satisfy third
               party "objectivity" standards under Code Section 162(m), and the
               regulations promulgated thereunder.

     (c)       The Performance Criteria shall not allow for any discretion by
               the Committee as to an increase in any Award, but discretion to
               lower an Award is permissible.

     (d)       The Award and payment of any Award under this Plan to a Covered
               Participant with respect to a relevant Performance Period shall
               be contingent upon the attainment of the Performance Criteria
               that are applicable to such Award. The Committee shall certify in
               writing prior to payment of any such Award that such applicable
               Performance Criteria have been satisfied. Resolutions adopted by
               the Committee may be used for this purpose.

     (e)       The aggregate maximum Awards that may be paid (in cash or in
               shares of Stock or a combination thereof) to any Covered
               Participant under the Plan pursuant to Sections 8, 9, 10 and 11
               during any calendar year shall be an amount equivalent to the
               fair market value of 100,000 shares of Stock, such fair market
               value to be determined as of the first day of such calendar year.

     (f)       The aggregate maximum number of shares of Stock subject to
               Options and SARs made to any Covered Participant during any
               calendar year shall be 100,000.

     (g)       All Awards to Covered Participants under this Plan shall be
               further subject to such other conditions, restrictions, and
               requirements as the Committee may determine to be necessary to
               carry out the purposes of this Section 12.

and exercisable; (ii) all Periods of Restriction shall be deemed to have been
completed; (iii) all Performance Criteria shall be deemed to have been satisfied
in full; and (iv) all other restrictions of any kind applicable to all
outstanding Awards shall be deemed to have lapsed or been satisfied in full;
provided that none of the effects described in (i) - (iv) above shall occur if
the Change in Control, or the transaction, event or occurrence causing the
Change in Control was duly and effectively approved in advance by the
affirmative vote of a majority of the Company's Board of Directors.

Options, no Award granted under the Plan may be sold, transferred, pledged,
assigned or otherwise alienated or hypothecated, except by will or the laws of
descent and distribution.  Further, no lien, obligation, or liability of the
Participant may be assigned to any right or interest of any Participant in an

shares of Common Stock to be provided under the Plan until he or she has become
the holder of such shares.

     14.7      Construction of the Plan.  The Plan and all Agreements shall be
               ------------------------                                       
governed, construed, interpreted and administered in accordance with the laws of
the State of Texas.  In the event any provision of the Plan or any Agreement
shall be held invalid, illegal or unenforceable, in whole or in part, for any
reason, such determination shall not affect the validity, legality or
enforceability of any remaining provision, portion of provision or Plan overall,
which shall remain in full force and effect as if the Plan had been absent the
invalid, illegal or unenforceable provision or portion thereof.

     14.8      Amendment of Plan.  The Committee or the Board of Directors may 
               -----------------
amend, suspend, or terminate the Plan or any portion thereof at any time,

such approval is necessary to comply with any legal 

                                       15
<PAGE>
 
requirement, including for these purposes any approval requirement which is a
requirement for the performance-based compensation exception under Code Section
162(m).

     14.9      Amendment of Award.  In its sole and complete discretion, the
               ------------------                                           
Committee may at any time amend any Award for the following reasons: (i)

law, or other law or regulations applicable to the Award; or (ii) any other
event not described in clause (i) occurs and the Participant gives his or her
consent to such amendment.

included as "earnings," "wages," "salary" or "compensation" in any pension,
welfare, life insurance, or other employee benefit arrangement of the Company.

     14.11     Legend.  In its sole and complete discretion, the Committee may

               --------------------                                        
subject to Section 16(b) of the Exchange Act shall be deemed to include any such
additional terms, conditions, limitations and provisions as Rule 16b-3 requires,
unless the Committee in its discretion determines that any such Award should not
be governed by Rule 16b-3.  All performance-based Awards to Covered Participants
shall be deemed to include any such additional terms, conditions, limitations
and provisions as are necessary to comply with the performance-based
compensation exemption of Code Section 162(m), unless the Committee, in its
discretion, determines that any such Award is not intended to qualify for the
exemption for performance-based compensation under Code Section 162(m).

     14.13     Unfunded Plan.  The Plan is intended to constitute an unfunded
               -------------
