1.   BUSINESS MERGERS AND ACQUISITIONS

TUC
---

     On August 5, 1997, the merger transactions (Merger) provided for in a
previously announced agreement between Texas Utilities Company, now known as
Texas Energy Industries, Inc. (TEI) and ENSERCH Corporation (ENSERCH) were
completed. At the effective time of the Merger: (i) Texas Utilities Company
changed its name to TEI, (ii) TEI and ENSERCH merged with wholly-owned
subsidiaries of TUC Holding Company, which now owns all the common stock of TEI
and of ENSERCH, (iii) TUC Holding Company changed its name to Texas Utilities
Company (TUC), (iv) each share of TEI'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.

     Businesses and subsidiaries acquired in the Merger were Lone Star Gas
Company (Lone Star Gas), 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 Company (Lone Star Pipeline), one of the largest pipelines in the
United States, consisting of 8,000 miles of gathering and transmission pipelines
in Texas; and subsidiaries engaged in natural gas processing, natural gas
marketing, independent power production and international gas distribution
systems development.

     In the Merger, 15,861,272 shares of TUC common stock, valued at
approximately $565 million, were issued to former holders of ENSERCH common
stock. At the date of the Merger, ENSERCH had debt and preferred stock
outstanding of approximately $1.3 billion. (See Note 4.)

     The acquisition of ENSERCH was accounted for as a purchase business
combination. The assets and liabilities of ENSERCH, at the Merger date, August
5, 1997, were adjusted to their estimated fair values, and the excess of the
purchase price paid by TUC over the estimated fair value of ENSERCH's net assets
acquired and liabilities assumed was recorded as goodwill on ENSERCH's balance
sheet and is being amortized over 40 years. The process of determining the fair
value of assets and liabilities at the Merger date is continuing, and the final
result awaits the resolution of income tax and other contingencies and
finalization of some preliminary estimates. ENSERCH's results of operation, as
of the date of the acquisition, are reflected in the consolidated financial
statements of TUC and its subsidiaries.

     In August 1997, TUC announced that it had entered into a definitive
agreement to acquire Lufkin-Conroe Communications Co. (LCC). LCC is the parent
company of Lufkin-Conroe Telephone Exchange, Inc. (LCTX) and Lufkin-Conroe
Telecommunications Corporation (LCT) and its subsidiaries. LCTX is an
independent local exchange carrier which has provided telephone services for
almost 100 years, and as of September 1997, was the fourth largest telephone
company in Texas (28th largest in the United States). LCTX has sixteen exchanges
that serve approximately 100,000 access lines in the Alto, Conroe and Lufkin
areas of southeast Texas. It also provides access services to a number of
interexchange carriers, who provide long distance services. LCT and its
subsidiaries own fiber optic cable systems which they lease to interexchange
carriers, provide Internet access, radio communications tower rentals, cellular
mobile telephones and radio paging services and private branch exchange service
to local customers. LCT, through a subsidiary, also provides interexchange long
distance service, with a primary focus on business customers. TUC is expected to
issue approximately $320 million of TUC's common stock to LCC shareholders in a
stock for stock exchange, and TUC would assume approximately $8 million of LCC's
debt. The acquisition is subject to certain conditions which include the
approval of LCC shareholders. The acquisition of LCC will be accounted for as a
purchase business combination.

2.   SIGNIFICANT ACCOUNTING POLICIES

TUC AND TU ELECTRIC
-------------------

     BASIS OF PRESENTATION -- The condensed consolidated financial statements of
TUC 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 on Form 10-K of TEI, formerly Texas Utilities Company, and
TU Electric and, in the opinion of TUC or

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

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.
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 TEI and TU Electric included in the 1996 Annual
Reports on Form 10-K of TEI and TU Electric, and the information under
Management's Discussion and Analysis of Financial Condition and Results of
Operation herein. TUC 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 TUC'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.

TUC
---

     CONSOLIDATION -- Prior to August 5, 1997, the date of the Merger, TUC did
not have any assets or operations. Pursuant to the Merger, TUC became the parent
of each of TEI and ENSERCH. For financial reporting purposes, TUC is being
treated as the successor to TEI. Unless otherwise specified, all references to
TUC, which relate to a period prior to August 5, 1997, shall be deemed to be
references to TEI. Since the acquisition of ENSERCH has been accounted for as a
purchase business combination, no financial and other information for ENSERCH is
presented for periods prior to the date of acquisition. The condensed
consolidated financial statements for the three-, nine- and twelve-months ended
September 30, 1997 and as of September 30, 1997, include TEI and all of its
majority-owned subsidiaries for all periods and ENSERCH and all of its majority-
owned subsidiaries only from August 5, 1997 and as of September 30, 1997. The
condensed consolidated financial statements for the three-, nine- and twelve-
months ended September 30, 1996 and as of September 30, 1996, include TEI and
all of its majority-owned subsidiaries for all periods and do not include
ENSERCH or any of its subsidiaries for any periods.

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

     CONSOLIDATED CASH FLOWS -- The supplemental schedule below details TUC's
noncash investing and financing activities:

     ENERGY MARKETING ACTIVITIES -- Certain System Companies enter into a 
variety of transactions and derivative financial instruments, including swaps, 
options, futures and other contractual arrangements. These activities are 
accounted for using the mark-to-market method, under which, changes in the 
market value of outstanding financial instruments are recognized as gains or 
losses in the period of change.
     
     GOODWILL -- The difference of $1,140,701,000 between the amount at which
the investments in subsidiaries is carried by TUC and the underlying book equity
of such subsidiaries is included in goodwill.    

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.

3.   SHORT-TERM FINANCING

TUC AND TU ELECTRIC
-------------------

     At September 30, 1997, TUC, TU Electric and ENSERCH had joint lines of
credit under credit facility agreements (Credit Agreements) with a group of
commercial banks. The Credit Agreements have two 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. The
combined borrowings of TUC, TU Electric and ENSERCH under both facilities are
limited to an aggregate of $1,900,000,000 outstanding at any one time. ENSERCH's
borrowings under both facilities are limited to an aggregate of up to
$650,000,000 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 TUC at September 30, 1997, from banks or other lenders, was
$2,150,000,000.

     Following the Merger, ENSERCH's commercial paper program and bank lines in
the form of a revolving credit agreement were discontinued. ENSERCH retired its
$204,500,000 commercial paper balance and its $260,400,000 long-term debt
balance outstanding under the credit agreement. TUC advances to ENSERCH
to fund these retirements and to provide for other cash needs totalled $512, 
300,000 at September 30, 1997.

     In addition, two ENSERCH subsidiaries have revolving credit agreements
aggregating $30,000,000, of which $25,000,000 was outstanding at September 30,
1997.  These revolving credit agreements expire on March 31, 2000.

4.   CAPITALIZATION

TUC
---

     COMMON STOCK --During the nine months ended September 30, 1997, common
stock equity increased by $6,070,000 due to an allocation to the accounts of
participants in TUC's Employee Thrift Plan (Thrift Plan) of TUC common stock
held by the Thrift Plan Trustee.

     In August 1997, TUC issued 15,861,272 shares of its authorized but unissued
common stock to former holders of ENSERCH common stock pursuant to provisions of
the Merger (see Note 1).  In June and September 1997, TUC sold, for
approximately $1,926,000, 58,000 shares of its authorized but unissued common
stock under the Long-Term Incentive Compensation Plan of Texas Utilities Company
System.

     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.

(a)  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 the bonds are determined weekly and daily.

     In October 1997, the Trinity River Authority of Texas (Trinity Authority)
issued $14,075,000 aggregate principal amount of Pollution Control Revenue Bonds
due October 1, 2032. The bonds have variable interest rates and are subject to
mandatory or optional tender and remarketing from time to time. Pursuant to an
Installment Payment and Bond Amortization Agreement with the Trinity Authority,
TU Electric is obligated to make payment of the purchase price of the bonds upon
mandatory or optional tender and of the principal of and interest on the bonds.
Such payments are supported by an irrevocable letter of credit. Draws under the
letter of credit are reimbursable by TU Electric. Interest rates on the bonds
are determined at varying intervals. At the time of issuance, the interest rate
was 5.60%.

     During the nine months ended September 30, 1997, TU Electric redeemed,
reacquired or made principal payments on the following long-term debt:

5.   DERIVATIVE INSTRUMENTS

TUC AND TU ELECTRIC
-------------------

     TUC's and TU Electric's operations involve managing market risks related to
changes in interest rates and, for TUC, foreign exchange and commodity price
exposures.  Derivative instruments including swaps and forward contracts are
used to reduce and manage a portion of those risks.  TUC's, with the exception
of the marketing activities of an ENSERCH subsidiary, Enserch Energy Services,
Inc. (EES), and TU Electric's participations in derivative transactions are
designed for hedging purposes; and derivative instruments are not held or issued
for trading purposes.

     INTEREST RATE RISK MANAGEMENT -- At September 30, 1997, Eastern Energy
Limited (Eastern Energy), a wholly-owned indirect subsidiary of TUC, had
interest rate swaps outstanding with respect to certain of its debt with an
aggregate notional amount of $836,193,000. 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.

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


     FOREIGN EXCHANGE RISK MANAGEMENT -- TUC's foreign exchange exposures result
from transactions denominated in currencies other than the local currency of its
foreign subsidiary. At September 30, 1997, Eastern Energy had cross-currency
swap agreements outstanding with an aggregate notional amount of $313,617,000
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 prices. 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.

     NATURAL GAS MARKETING ACTIVITIES -- TUC, through EES, is a marketer of
natural gas and natural gas services. As part of these business activities, EES
enters into a variety of transactions, including forward contracts that
principally involve physical delivery of natural gas, and derivative financial
instruments, including swaps, options, futures and other contractual
arrangements. The derivative transactions are concentrated with established
energy companies and major financial institutions.

     EES's marketing activities involve price commitments into the future and,
therefore, give rise to market risk, which represents the potential loss that
can be caused by a change in the market value of a particular commitment. Net
open portfolio positions often result from the origination of new transactions
or in response to changing market conditions.

     EES enters into contracts to purchase and sell natural gas for physical
delivery in the future.  At September 30, 1997, EES had net commitments to sell
approximately 41.0 billion cubic feet (Bcf) of natural gas through the year 2003
with offsetting net financial positions to purchase approximately 48.1 Bcf.

     CREDIT RISK  --  Credit risk relates to the risk of loss that TUC, TU
Electric and ENSERCH would incur as a result of nonperformance by counterparties
to their respective derivative instruments. TUC and TU Electric believe the risk
of nonperformance by counterparties is minimal.

6.   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. 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 and to leave rates unchanged during the remainder of 1997. TU
Electric recorded the charge to revenues in July 1997 and included the refunds
in August 1997 billings. 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 and, at this time, 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 $80 million of
eligible fuel related costs (including interest) incurred during the
reconciliation period (Fuel Disallowance). The majority of the Fuel 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 received a
final written order from the PUC and recorded the charge to revenues in August
1997. TU Electric strongly disagrees with the Fuel Disallowance and continues to
vigorously defend its position. TU Electric has appealed the PUC's order to the
District Court of Travis County, Texas.

     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 (Fuel Refund).  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.  Customer refunds were
included in August 1997 billings.  A final order confirming the Fuel Refund was
entered by the PUC in October 1997.

TUC
---

     In October 1996, Lone Star Pipeline (a division of ENSERCH), filed a
request with the Railroad Commission of Texas (RRC) to increase the rate it
charges Lone Star Gas (a division of ENSERCH), to store and transport gas
ultimately destined for residential and commercial customers in the 550 Texas
cities and towns served by Lone Star Gas. Lone Star Gas also requested that the
RRC separately set rates for costs to aggregate gas supply for these cities.
Rates currently in effect were set by the RRC in 1982. The purpose of the rate
request was to allow for the recovery of a substantial increase in the cost of
doing business since 1982 and to cover significant capital investments of
approximately $420 million made during the past 14 years to maintain and improve
the reliability and safety of the pipeline system and help reduce natural-gas
supply costs.

     In May 1997, the RRC issued an order setting new rates for ENSERCH that
would have reduced the current margin by approximately 7 percent. The order
would allow 100 percent recovery of gas cost subject to a reconciliation
procedure after three years and would impose certain restrictions on the
recovery of gas purchased from affiliates. ENSERCH and other parties to the case
filed motions for rehearing of the order. In August 1997, the RRC issued an
order partially granting and partially denying the motions for rehearing. The
August order reduces the current margin an additional 3 percent beyond the May
20 order.

     The August order was met with additional motions for rehearing which were
granted in part and denied in part.  On September 30, 1997, the RRC issued a
second order on rehearing, which did not change the margin set in the prior
order. On November 4, 1997, the RRC acted on the motions for rehearing filed in
response to the September 30, 1997 order by denying the motions.  Pursuant to
the tariffs approved by the RRC, the new rates will become effective on December
1, 1997, if no further changes to the order are made.  ENSERCH has 30 days to
appeal the decision.

     Prior to the ENSERCH filing of a request for a rate increase, the RRC
ordered a general inquiry into the rates and services of Lone Star Gas. The
scope of the inquiry has not been defined fully, but it will focus initially on
historical gas costs and unbundling issues. A hearing on the gas cost issues is
set to begin in August 1998. TUC management is unable to determine at this time
the ultimate outcome of this inquiry.

7.   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, $30,475,000 at September 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 September 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 the 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 September 30, 1997, such reserve
totaled $114,393,000 which includes an accrual of $13,634,000 and $18,179,000
for the nine and twelve months ended September 30, 1997, respectively. As of
September 30, 1997, the market value of assets in the external trust fund for
decommissioning of Comanche Peak was $151,131,000. 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.

TUC AND TU ELECTRIC
-------------------

GENERAL

     In addition to the above, TUC 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.

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 September 30, 1997, and
the related condensed statements of consolidated income for the three-month,
nine-month and twelve-month periods ended September 30, 1997 and 1996, and of
consolidated cash flows for the nine-month periods ended September 30, 1997 and
1996. These financial statements are the responsibility of TUC'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 Texas Energy Industries, Inc. 
(TEI), formerly Texas Utilities 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 TEI'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.

         OF OPERATION

FORWARD-LOOKING STATEMENTS

TUC AND TU ELECTRIC
-------------------

     This report and other presentations made by Texas Utilities Company (TUC)
and its direct and indirect subsidiaries (System Companies) 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 TUC 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 TUC 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 Railroad Commission of Texas (RRC), the Nuclear
Regulatory Commission, and, in the case of TUC, 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, (x) legal and administrative proceedings and
settlements, (xi) inability of the various counterparties to meet their
obligations with respect to TUC's and TU Electric's financial instruments, (xii)
changes in technology used and services offered by TUC and TU Electric, and
(xiii) significant changes in TUC's relationship with its employees and the
potential adverse effects if labor disputes or grievances were to occur.

     Any forward-looking statement speaks only as of the date on which such
statement is made, and neither TUC 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 TUC 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.

BUSINESS MERGERS AND ACQUISITIONS

TUC
---

     On August 5, 1997, the merger transactions (Merger) provided for in a
previously announced agreement between Texas Utilities Company, now known as
Texas Energy Industries, Inc. (TEI) and ENSERCH Corporation (ENSERCH) were
completed. At the effective time of the Merger: (i) Texas Utilities Company
changed its name to TEI, (ii) TEI and ENSERCH merged with wholly-owned
subsidiaries of TUC Holding Company, which now owns all the common stock of TEI
and of ENSERCH, (iii) TUC Holding Company changed its name to TUC, (iv) each
share of TEI'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.

     Businesses and subsidiaries acquired in the Merger were Lone Star Gas
Company (Lone Star Gas), 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 Company (Lone Star Pipeline), one of the largest pipelines in the
United States, consisting of 8,000 miles of gathering and transmission pipelines
in Texas; and subsidiaries engaged in natural gas processing, natural gas
marketing, independent power production and international gas distribution
systems development.

     In the Merger, 15,861,272 shares of TUC common stock, valued at
approximately $565 million, were issued to former holders of ENSERCH common
stock. At the date of the Merger, ENSERCH had debt and preferred stock
outstanding of approximately $1.3 billion. (See Note 4 to Condensed Consolidated
Financial Statements.)

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

     The acquisition of ENSERCH was accounted for as a purchase business
combination. The assets and liabilities of ENSERCH, at the Merger date, August
5, 1997, were adjusted to their estimated fair values, and the excess of the
purchase price paid by TUC over the estimated fair value of ENSERCH's net assets
acquired and liabilities assumed was recorded as goodwill on ENSERCH's balance
sheet and is being amortized over 40 years. The process of determining the fair
value of assets and liabilities at the Merger date is continuing, and the final
result awaits the resolution of income tax and other contingencies and
finalization of some preliminary estimates. ENSERCH's results of operation, from
the date of the acquisition, are reflected in the consolidated financial
statements of TUC and its subsidiaries.

     In August 1997, TUC announced that it had entered into a definitive
agreement to acquire Lufkin-Conroe Communications Co. (LCC). LCC is the parent
company of Lufkin-Conroe Telephone Exchange, Inc. (LCTX) and Lufkin-Conroe
Telecommunications Corporation (LCT) and its subsidiaries. LCTX is an
independent local exchange carrier which has provided telephone services for
almost 100 years, and as of September 1997, was the fourth largest telephone
company in Texas (28th largest in the United States). LCTX has sixteen exchanges
that serve approximately 100,000 access lines in the Alto, Conroe and Lufkin
areas of southeast Texas. It also provides access services to a number of
interexchange carriers, who provide long distance services. LCT and its
subsidiaries own fiber optic cable systems which they lease to interexchange
carriers, provide Internet access, radio communications tower rentals, cellular
mobile telephones and radio paging services and private branch exchange service
to local customers. LCT, through a subsidiary, also provides interexchange long
distance service, with a primary focus on business customers. TUC is expected to
issue approximately $320 million of TUC's common stock to LCC shareholders in a
stock for stock exchange, and TUC would assume approximately $8 million of LCC's
debt. The acquisition is subject to certain conditions which include the
approval of LCC shareholders. The acquisition of LCC will be accounted for as a
purchase business combination.

GENERAL

TUC
---

     Prior to August 5, 1997, the date of the Merger, TUC did not have any
assets or operations. Pursuant to the Merger, TUC became the parent of each of
TEI and ENSERCH. For financial reporting purposes, TUC is being treated as the
successor to TEI. Unless otherwise specified, all references to TUC, which
relate to a period prior to August 5, 1997, shall be deemed to be references to
TEI. Since the acquisition of ENSERCH has been accounted for as a purchase
business combination, no financial and other information for ENSERCH is
presented for periods prior to the date of acquisition. The condensed
consolidated financial statements for the three-, nine- and twelve-months ended
September 30, 1997 and as of September 30, 1997, include TEI and all of its
majority-owned subsidiaries for all periods and ENSERCH and all of its majority-
owned subsidiaries only from August 5, 1997 and as of September 30, 1997. The
condensed consolidated financial statements for the three-, nine- and twelve-
months ended September 30, 1996 and as of September 30, 1996, include TEI and
all of its majority-owned subsidiaries for all periods and does not include
ENSERCH or any of its subsidiaries for any periods.

     Certain TUC comparisons in this Quarterly Report on Form 10-Q have been
affected by the August 1997 acquisition of ENSERCH by TUC and the December 1995
acquisition of Eastern Energy Limited (Eastern Energy) by Texas Utilities
Australia Pty. Ltd. (TU Australia), a wholly-owned subsidiary of TEI. The
results of operation of ENSERCH and Eastern Energy are included only for the
periods subsequent to their respective dates of acquisition.

Management's Discussion and Analysis of Financial Condition and Results of
Operation in TEI's and TU Electric's 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 System Companies have occurred subsequent to year-end other
than as disclosed in other reports of TUC, TEI, TU Electric and ENSERCH or
included herein.

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

     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 System Companies
at September 30, 1997 consisted of approximately 54% long-term debt, 5%
preferred securities of trusts, 2% preferred stock and 39% common stock equity.
The capitalization ratios of TU Electric at September 30, 1997 consisted of
approximately 46% long-term debt, 6% preferred securities of trusts, 1%
preferred stock and 47% common stock equity.

     In October 1997, TUC issued $125,000,000 aggregate principal amount of its
6.20% Series A Senior Notes due 2002, and $175,000,000 aggregate principal
amount of its 6.375% Series B Senior Notes due 2004.  Payment of the principal
of and interest on the Senior Notes, when due or at maturity, is guaranteed by a
financial guaranty insurance policy.
 
     In October 1997, the Trinity River Authority of Texas issued $14,075,000
aggregate principal amount of Pollution Control Revenue Bonds due October 1,
2032 (Taxable Bonds). 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, 2022 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/or remarketing from time to time. The
remarketing of the bonds is supported by standby bond purchase agreements, or in
the case of the Taxable Bonds, a direct-pay letter of credit. Scheduled payments
of interest and of principal at maturity or on mandatory redemption, upon the
occurrence of certain events with respect to such bonds are supported by
insurance policies or, in the case of the Taxable Bonds, a direct-pay letter of
credit. Interest rates on the bonds are determined daily, weekly and/or
multiannually or for variable rate periods . Currently, such rates range from
3.70% to 5.60%.

     In August 1997, TU Electric issued $300,000,000 aggregate principal amount
of 7.17% Unsecured Debentures due 2007.

     To date in 1997, the System Companies have redeemed, reacquired or made
principal payments of $2,339,407,000 (including $1,766,275,000 for TU Electric)
on long-term debt and preferred stock.

     In March 1997, TEI completed its tender offer for any and all shares of 20
series of TU Electric's preferred stock, including preferred stock underlying
depositary shares.  TEI funded the purchase of 3,989,640 shares of  preferred
stock at a total cost of approximately $404,000,000 primarily through the
issuance of commercial paper.  In May and June 1997, TEI 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 a
portion of proceeds from the sale of capital securities in January 1997.

     At September 30, 1997, TUC, TU Electric and ENSERCH had joint lines of
credit under credit facility agreements (Credit Agreements) with a group of
commercial banks. The Credit Agreements have two 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. The
combined borrowings of TUC, TU Electric and ENSERCH under both facilities are
limited to an aggregate of $1,900,000,000 outstanding at any one time. ENSERCH's
borrowings under both facilities are limited to an aggregate of up to
$650,000,000 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 TUC at September 30, 1997, from banks or other lenders, was
$2,150,000,000.

     Following the Merger, ENSERCH's commercial paper program and and bank lines
in the form of a revolving credit agreement were discontinued. ENSERCH retired
its $204,500,000 commercial paper balance and its $260,400,000 long-term debt
balance outstanding under the credit agreement. TUC advances to ENSERCH to fund
these retirements and to provide for other cash needs totalled $512,300,000 at
September 30, 1997.

     In addition, two ENSERCH subsidiaries have revolving credit agreements
aggregating $30,000,000, of which $25,000,000 was outstanding at September 30,
1997. These revolving credit agreements expire on March 31, 2000.

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

     The System Companies may issue additional debt and equity securities as
needed, including the possible future sale: (i) by TU Electric of up to
$148,850,000 principal amount of debt securities, (ii) by TU Electric of up to
250,000 shares of Cumulative Preferred Stock ($100 liquidation value), and (iii)
by ENSERCH of up to $225,000,000 aggregate principal amount of securities, all
of which are currently registered with the Securities and Exchange Commission
(SEC) for offering pursuant to Rule 415 under the Securities Act of 1933.

     TUC's and TU Electric's operations involve managing market risks related to
changes in interest rates and, for TUC, foreign exchange and commodity price
exposures. Derivative instruments including swaps and forward contracts are used
to reduce and manage a portion of those risks. TUC's, with the exception of the
marketing activities of an ENSERCH subsidiary, Enserch Energy Services, Inc.
(EES), and TU Electric's participations in derivative transactions are designed
for hedging purposes; and derivative instruments are not held or issued for
trading purposes. TUC's foreign exchange exposures result from transactions
denominated in currencies other than the local currency of its foreign
subsidiary. As of September 30, 1997, the aggregate notional amount of such
exposure was $313,617,000. TUC enters into currency swaps to reduce foreign
exchange exposure. As of September 30, 1997, net deferred gains and losses
associated with the currency swaps were not material. As part of its natural gas
marketing activities, EES enters into forward contracts that principally involve
physical delivery of natural gas and derivative financial instruments, including
swaps, options, futures and other contractual arrangements to offset price risks
of gas supply. These activities involve price commitments into the future and,
therefore, give rise to market risk. EES applies mark-to-market accounting to
its business activities. At September 30, 1997, natural gas marketing operations
had net commitments to sell approximately 41.0 billion cubic feet (Bcf) of
natural gas through the year 2003 with offsetting net financial positions to
purchase approximately 48.1 Bcf. Credit risk relates to the risk of loss that
TUC, TU Electric and ENSERCH would incur as a result of nonperformance by
counterparties to their respective derivative instruments. TUC and TU Electric
believe the risk of nonperformance by counterparties is minimal. For other
information regarding derivative instruments, see Note 5 to Condensed
Consolidated Financial Statements.

REGULATION, RATES AND COMPETITION

TUC AND TU ELECTRIC
-------------------

     Under the current regulatory environment, certain System Companies 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 a company no longer meets the criteria for application of SFAS 71 due to
significant changes in regulation or competition, the affected company would
discontinue the application of SFAS 71. If a portion of the affected 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, the affected company would be required to
assess the recoverability of certain assets, including plant, and, if impaired,
to write down the assets to reflect their fair market value. The System
Companies cannot predict whether or to what extent changes may occur requiring
the partial or complete discontinuation of SFAS 71 application.

     In order to remain competitive, TUC 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.

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. 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 (Rate Settlement), and to leave rates unchanged during the
remainder of 1997. TU Electric recorded the charge to revenues in

                                       24

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

July 1997 and included the refunds in August 1997 billings.  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 and, at this time,  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
$80 billion). In the ruling, the PUC disallowed approximately $80 million of
eligible fuel related costs (including interest) incurred during the
reconciliation period (Fuel Disallowance). The majority of the Fuel 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 received a
final written order from the PUC and recorded the charge to revenues in August
1997. TU Electric strongly disagrees with the Fuel Disallowance and continues to
vigorously defend its position. TU Electric has appealed the PUC's order to the
District Court of Travis County, Texas.

     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 (Fuel Refund).  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.  Customer refunds were
included in August 1997 billings.  A final order confirming the Fuel Refund was
entered by the PUC in October 1997.

     While TU Electric has experienced competitive pressures in the wholesale
market resulting in a small loss of load  since the beginning of 1993, wholesale
sales represented a relatively low percentage of TU Electric's consolidated
operating revenues for the three-, nine- and twelve-month periods ended
September 30, 1997.  TU Electric is 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 its operations.

TUC
---

     In October 1996, Lone Star Pipeline (a division of ENSERCH), filed a
request with the RRC to increase the rate it charges Lone Star Gas (a division
of ENSERCH), to store and transport gas ultimately destined for residential and
commercial customers in the 550 Texas cities and towns served by Lone Star Gas.
Lone Star Gas also requested that the RRC separately set rates for costs to
aggregate gas supply for these cities. Rates currently in effect were set by the
RRC in 1982. The purpose of the rate request was to allow for the recovery of a
substantial increase in the cost of doing business since 1982 and to cover
significant capital investments of approximately $420 million made during the
past 14 years to maintain and improve the reliability and safety of the pipeline
system and help reduce natural-gas supply costs.

     In May 1997, the RRC issued an order setting new rates for ENSERCH that
would have reduced the current margin by approximately 7 percent. The order
would allow 100 percent recovery of gas cost subject to a reconciliation
procedure after three years and would impose certain restrictions on the
recovery of gas purchased from affiliates. ENSERCH and other parties to the case
filed motions for rehearing of the order. In August 1997, the RRC issued an
order partially granting and partially denying the motions for rehearing. The
August order reduces the current margin an additional 3 percent beyond the May
20 order.

     The August order was met with additional motions for rehearing which were
granted in part and denied in part.  On September 30, 1997, the RRC issued a
second order on rehearing, which did not change the margin set in the prior
order. On November 4, 1997, the RRC acted on the motions for rehearing filed in
response to the September 30, 1997 order by denying the motions.  Pursuant to
the tariffs approved by the RRC, the new rates will become effective on December
1, 1997, if no further changes to the order are made.  ENSERCH has 30 days to
appeal the decision.

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

     Prior to the ENSERCH filing of a request for a rate increase, the RRC
ordered a general inquiry into the rates and services of Lone Star Gas. The
scope of the inquiry has not been defined fully, but it will focus initially on
historical gas costs and unbundling issues. A hearing on the gas cost issues is
set to begin in August 1998. TUC Management is unable to determine at this time
the ultimate outcome of this inquiry.

CAPITAL EXPENDITURES

TUC AND TU ELECTRIC
-------------------

     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 TUC'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.

     TUC 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.

RESULTS OF OPERATION

TUC
---

     For the three-, nine- and twelve-month periods ended September 30, 1997,
TUC's consolidated net income decreased approximately 19%, 18% and 18% as
compared to the respective periods ended September 30, 1996.  For TUC and TU
Electric, from which most of  TUC's consolidated earnings is derived, the major
factors affecting earnings for all current periods were more normal weather
conditions as compared to the respective prior periods, the Rate Settlement and
the Fuel Disallowance.

     TUC's condensed statement of consolidated income for the three-, nine- and
twelve-month periods ended September 30, 1997, is affected by the results of
operation of ENSERCH which are included for the periods subsequent to August 5,
1997. For the twelve months ended September 30, 1997, TUC's condensed statement
of consolidated income includes operating revenues of $277 million, operating
expenses of $278 million (including income tax benefits) and interest expense
and preferred stock dividends of $15 million, which represent ENSERCH's results
of operation.
 
     TUC's condensed statement of consolidated income for the twelve-month
period ended September 30, 1997, is also affected by a full twelve month's
results of operation of Eastern Energy, which was acquired by TU Australia in
December 1995. For the twelve months ended September 30, 1997, TUC's condensed
statement of consolidated income includes operating revenues of $496 million,
operating expenses of $404 million (including income tax expense) and interest
expense of $79 million, which represent Eastern Energy's results of operation.

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

     For the three- and twelve-month periods, operating revenues increased
approximately 4% and 1%, respectively. Operating revenues decreased
approximately 1% for the nine-month period.  The following table details the
factors contributing to these changes:

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

     Total energy sales for the three-, nine-and twelve-month periods increased
by approximately 8%, 1% and 2%, respectively. Total energy sales for the three-
month period increased primarily as a result of warmer weather conditions as
compared to the prior period. Total energy sales did not change significantly
for the nine- and twelve-month periods. The increase in base rate revenue for
the three-month period is due primarily to warmer weather conditions partially
offset by the Rate Settlement. The decrease in base rate revenue for the nine-
and twelve-month periods was due primarily to the Rate Settlement and milder
weather, partially offset by customer growth. Increases in transmission service
revenue for the three-, nine- and twelve-month periods are due to the
recognition of revenues from implementing the PUC's Open Access Transmission
Rule effective January 1, 1997. Other revenues decreased for all periods due
primarily to the deferral in August 1997 of previous gains on the sale of sulfur
dioxide allowances and the classification of wheeling revenues as other revenues
in prior periods.

     Fuel revenue for the three-month and twelve-month periods increased as a
result of increases in energy sales, partially offset by the Fuel Disallowance.
The decrease in fuel revenue for the nine-month period was primarily due to the
Fuel Disallowance.

     Fuel and purchased power expense for the three-, nine- and twelve-month
periods increased 15%, 2% and 6%, respectively, primarily due to increased
energy sales as compared to the prior periods and increases in spot market gas
prices.

     Operation and maintenance expenses increased for the three-, nine-, and
twelve-month periods due primarily to transmission tariffs implemented in
January 1997.

     Other income and (deductions) -- net was affected for the three-, nine- and
twelve-month periods, as compared to prior periods, by a gain on disposition of
property in July 1996.

     Income tax benefits related to other income decreased for the nine-month
and twelve-month periods primarily due to an IRS audit adjustment reflected in
the respective prior periods and 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 2 to Condensed Consolidated Financial
Statements). The resulting increase in TU Electric's effective income tax rate
increased the value of its unamortized regulatory 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-, nine- and
twelve-month periods were affected by the prepayment in August and September
1996 of TU Electric's borrowings under a term credit agreement. Other interest
increased for the three-month period due primarily to interest related to the
PUC's disallowance of eligible fuel related costs in 1997. Other interest
decreased for the nine- and twelve-month periods due primarily to an interest
payment related to a settlement with the Internal Revenue Service in June 1996,
partially offset by interest related to the Fuel Disallowance. Increases in
distribution on preferred securities of trusts resulted from the issuance, in
December 1995 and January 1997, of TU Electric obligated, mandatorily
redeemable, preferred securities of trusts.

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

ACCOUNTING CHANGE

     TUC intends to adopt Financial Accounting Standards Board Statement No.
131, "Disclosures About Segments of an Enterprise and Related Information," in
its 1998 annual report when it is required. This statement establishes standards
for defining and reporting business segments. TUC is currently determining the
appropriate segments to be covered by this disclosure.

                          PART II. OTHER INFORMATION


ITEM 1.  LEGAL PROCEEDINGS

TUC
---

     As previously reported in the 1996 Annual Report on Form 10-K of TEI, in
October 1995, the Antitrust Division of the U.S. Department of Justice (DOJ)
submitted a civil investigative demand (CID) to TEI.  The CID requested
documents and information relating to an investigation of whether alleged tying
arrangements or other actions that unreasonably deny or condition access to TU
Electric's transmission system by others had occurred in violation of certain
antitrust laws.  In response, TEI submitted various documents and information to
the DOJ.  By letter dated November 4, 1997, the DOJ has advised TEI that the CID
investigation has been closed and the documents will be returned.
