ITEM 7. FINANCIAL STATEMENTS AND SCHEDULES
 
  The financial information listed below is filed herewith in connection with
a proposed merger of ENSERCH Corporation ("ENSERCH") with TUC Holding Company
("TUC"). In a related transaction, the operations of Lone Star Energy Plant
Operations, Inc. ("LSEPO"), an indirect wholly owned subsidiary of ENSERCH,
will merge with Enserch Exploration, Inc. ("EEX"), a company approximately 83%
owned by ENSERCH. LSEPO will be the surviving corporation of that merger (the
"Merger"), in which its name will be changed to Enserch Exploration, Inc.
("New EEX"). In the Merger each outstanding share of EEX Common Stock will be
converted into one share of new EEX Common Stock and the outstanding shares of
LSEPO will be converted into a number of shares of new EEX Common Stock
determined by dividing $7.0 million by the average of the closing sales prices
of EEX Common Stock on the 15 trading days preceding the fifth trading day
prior to the effective time of the Merger. References to the "EEX 1995 Form
10-K" refer to the EEX Annual Report on Form 10-K for the year ended December
31, 1995, and references to the "EEX 1996 Form 10-Q" refer to the EEX

                   UNAUDITED PRO FORMA FINANCIAL INFORMATION
                                  OF NEW EEX
 
  The following unaudited pro forma financial statements give effect to the
Merger. The unaudited condensed pro forma balance sheet as of June 30, 1996 is
presented as if the Merger had occurred on that date. The unaudited pro forma
statements of operations for each of the three years in the period ended
December 31, 1995 and the six months ended June 30, 1996 assume that the
Merger occurred at the beginning of each period presented. For purposes of
financial reporting, the Merger will be treated as a combination of entities
under common control. Accordingly, the assets and liabilities of EEX and LSEPO
will be recorded at their historical amounts.
 
  The unaudited pro forma financial statements should be read in conjunction
with the historical financial statements of EEX and LSEPO and "Management's
Discussion and Analysis of Financial Condition and Results of Operations" of
EEX and LSEPO included or incorporated by reference herein. The unaudited pro
forma statements of operations are not necessarily indicative of the financial
results that would have occurred had the Merger been consummated on the
indicated dates, nor are they necessarily indicative of future financial
results.
 
  On June 8, 1995, EEX acquired all of the capital stock of DALEN Corporation.
The acquisition was accounted for as a purchase. See Note (d) to the Unaudited
Pro Forma Financial Statements for a summary of pro forma results of
operations of New EEX reflecting the DALEN acquisition.

               NOTES TO UNAUDITED PRO FORMA FINANCIAL STATEMENTS
 
(a) Immediately prior to the effective time of the Merger, ENSERCH will make a
    capital contribution to LSEPO, or LSEPO will make a distribution to
    ENSERCH, in an amount sufficient to cause LSEPO's working capital to be
    $3.5 million. Following the Merger, ENSERCH will no longer fund LSEPO's
    operations.
 
(b) In the Merger each outstanding share of EEX Common Stock will be converted
    into one share of New EEX Common Stock and the outstanding shares of LSEPO
    will be converted into a number of shares of New EEX Common Stock
    determined by dividing $7.0 million by the average of the closing sales
    prices of EEX Common Stock on the 15 trading days preceding the fifth
    trading day prior to the effective time of the Merger. An average market
    price of EEX shares of $9.00 was assumed to determine the pro forma
    converted shares outstanding and to compute pro forma earnings per share.
 
(c) For periods prior to 1995, except for international and SACROC operations,
    EEX operated as a partnership, and the income or loss of the partnership
    was includable in the tax returns of the individual partners. Accordingly,
    no recognition was given to income taxes on partnership operations. EEX,
    as a corporation, is a taxable entity. The statements of operations for
    periods prior to 1995 include a pro forma provision for income taxes on
    the partnership operations based on the applicable corporate federal
    statutory rate.
 
(d) On June 8, 1995, EEX acquired all the capital stock of DALEN Corporation
    (DALEN) for cash of $340 million and assumed DALEN's bank debt of $115
    million. The acquisition was accounted for as a purchase. The assets
    acquired and the liabilities assumed were recorded at their estimated fair
    value. Essentially all of the valuation adjustment was assigned to gas and
    oil properties.
 
    Following is a summary of pro forma results of operations of New EEX
    assuming the DALEN acquisition had occurred at the beginning of the periods
    presented:

   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION ANDRESULTS OF
                                  OPERATIONS
 
OVERVIEW
 
  Lone Star Energy Plant Operations, Inc. ("LSEPO") has three agreements to
operate and maintain cogeneration plants. The agreements were initially
entered into by Lone Star Energy Company ("LSEC") and subsequently assigned to
LSEPO. The financial statements of LSEPO include the results of the three
operating and maintenance agreements for all years in a manner similar to a
pooling-of-interests since these activities were under the common control of
ENSERCH Corporation ("ENSERCH") and LSEC prior to the assignment of these
agreements to LSEPO.
 
  In connection with the proposed merger of ENSERCH with TUC Holding Company,
ENSERCH plans to merge the operations of LSEPO and Enserch Exploration, Inc.
("EEX"), a company approximately 83% owned by ENSERCH. LSEPO will be the
surviving corporation of that merger (the "Merger"), in which its name will be
changed to Enserch Exploration, Inc. ("New EEX"). In the Merger each
outstanding share of EEX Common Stock will be converted into one share of New
EEX Common Stock and the outstanding shares of LSEPO will be converted into a
number of shares of New EEX Common Stock determined by dividing $7.0 million
by the average of the closing sales prices of EEX Common Stock on the 15
trading days preceding the fifth trading day prior to the effective time of
the Merger.
 
RESULTS OF OPERATIONS
 
  Revenues include contract revenues and reimbursement of expenses incurred on
behalf of Encogen One Partners Ltd. ("Encogen One") and Encogen Four Partners,
L.P.
 
  LSEPO had net income of $1.4 million in 1995, compared with $.8 million in
1994 and $1.1 million in 1993. Operating income for 1995 was $2.2 million
versus $1.4 million in 1994 and $1.8 million in 1993. LSEPO receives incentive
fees based on the Buffalo and Bellingham plants' availability. In 1995, the
Buffalo and Bellingham plants achieved 98.6% and 98.3% availability,
respectively, which resulted in total incentive fees of $1.1 million being
earned. In 1994 and 1993, incentive fees of $.7 million and $.5 million,
respectively, were earned.
 
  LSEPO had net income of $182 thousand for the six months ended June 30, 1996
compared with $454 thousand for the same period in 1995. Operating income for
the first half of 1996 was $320 thousand versus $759 thousand for the first
half of 1995. The period to period reduction in operating income is largely
due to an increase in compensation expense in 1996 of $258 thousand and an
insurance premium refund of $128 thousand in 1995.
 
  Other income in 1995 consists principally of interest due from Encogen One.
During 1995, LSEPO incurred extraordinary reimbursable maintenance expenses
for Encogen One, which deferred reimbursement of these expenses to LSEPO, as
allowed under the terms of the operating and maintenance agreement. ENSERCH
has financed this temporary working capital requirement for LSEPO, and
interest equal to the interest earned by LSEPO is payable to ENSERCH.
 
LIQUIDITY AND FINANCIAL RESOURCES
 
  LSEPO has funded its activities through cash provided from operations and
through advances from ENSERCH. ENSERCH advances cash to LSEPO to meet its
working capital needs and LSEPO remits any excess cash to ENSERCH. Net cash
required by operating activities for 1995 totaled $2.4 million, compared with
cash provided of $1.4 million in 1994 and cash required of $2.2 million in
1993. Accounts receivable-trade at December 31, 1995 increased by $4.0 million
compared with the prior year end, largely as a result of higher receivables
from Encogen One for reimbursable expenses.
 
  Net cash provided by operating activities in the first six months of 1996
totaled $4.2 million compared with $4.3 million for the same period in 1995.
Accounts receivable-trade and the non-current deferred receivable from Encogen
One Partners Ltd. decreased by $4.1 million and $1.4 million, respectively,
from year-end 1995 to June 30, 1996.
 
  At June 30, 1996, LSEPO had total assets of $5.3 million and net assets of
$3.3 million, including working capital of $3.2 million. Immediately prior to
the Merger, ENSERCH will make a capital contribution to LSEPO, or LSEPO will
make a distribution to ENSERCH, in an amount sufficient to cause LSEPO's
working capital to be $3.5 million. Following the Merger, ENSERCH will no
longer fund LSEPO's operations.

                         INDEPENDENT AUDITORS' REPORT
 
  We have audited the accompanying balance sheets of Lone Star Energy Plant
Operations, Inc. (the "Company") as of December 31, 1995 and 1994, and the
related statements of income and retained earnings and of cash flows for each
of the three years in the period ended December 31, 1995. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, such financial statements present fairly, in all material
respects, the financial position of the Company at December 31, 1995 and 1994,
and the results of its operations and its cash flows for each of the three
years in the period ended December 31, 1995, in conformity with generally
accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
1. ORGANIZATION AND BUSINESS
 
  Lone Star Energy Plant Operations, Inc. ("LSEPO") is a wholly-owned
subsidiary of Lone Star Energy Company ("LSEC"), a wholly-owned subsidiary of
ENSERCH Corporation ("ENSERCH"). LSEPO has agreements to operate and maintain
three cogeneration plants, which are located in Sweetwater, Texas, in Buffalo,
New York, and in Bellingham, Washington. Each facility was developed by a
subsidiary of ENSERCH. LSEPO has fixed-cost operating and maintenance
agreements for providing labor and certain routine consumables at each plant,
with each of the agreements containing escalation provisions tied to
inflation. The agreements for the Buffalo and Bellingham plants also contain
bonus or penalty provisions based upon plant availability.
 
  The Sweetwater plant produces 255 megawatts per hour of electricity at
345,000 volts. This electricity is sold to the local electric utility (Texas
Utilities Electric Company). The facility also produces sequentially up to 170
MMBtu's per hour of exhaust gas at 1,000 degrees fahrenheit which is sold to a
gypsum board manufacturing facility for use in its drying process. The
Sweetwater plant commenced commercial operation in June 1989. The initial term
of LSEPO's agreement expires in June 2001.
 
  The Buffalo plant produces 62 megawatts per hour of electricity at 115,000
volts. This electricity is sold to the local electric utility (Niagara Mohawk
Power Company). The facility also produces up to 110,000 pounds per hour of
steam which is sold to a brass manufacturing facility for process use and
space heating purposes. The Buffalo plant commenced commercial operation in
May 1992. The initial term of LSEPO's agreement expires in March 2007.
 
  The Bellingham plant produces 160 megawatts per hour of electricity at
115,000 volts. This electricity is sold to the local electric utility (Puget
Sound Power and Light Company). The facility also produces up to 130,000
pounds per hour of steam which is sold to a paper mill for process purposes.
The Bellingham plant commenced commercial operation in July 1993. The initial
term of LSEPO's agreement expires in June 2008.
 
2. BASIS OF PRESENTATION
 
  Each of the three agreements LSEPO currently has to operate and maintain
cogeneration plants was initially entered into by LSEC and subsequently
assigned to LSEPO. The financial statements of LSEPO include the results of
the three operating and maintenance agreements for all years in a manner
similar to a pooling-of-interests since these activities were under the common
control of ENSERCH and LSEC prior to the assignment of these agreements to
LSEPO.
 
3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  All dollar amounts in the notes to financial statements are stated in
thousands unless otherwise indicated. The preparation of financial statements
requires the use of significant estimates and assumptions by management;
actual results could differ from those estimates.
 
  Revenues include contract revenues and reimbursement of expenses incurred on
behalf of Encogen One Partners Ltd. ("Encogen One") and Encogen Four Partners,
L.P.
 
  Depreciation of property, plant and equipment is provided principally by the
straight-line method over the estimated service lives of the related assets.
 
  During 1995, LSEPO incurred extraordinary reimbursable maintenance expenses
for Encogen One, which deferred reimbursement of these expenses to LSEPO, as
allowed under the terms of the operating and maintenance agreement. Encogen
One is charged interest at the prime rate plus one percent on the outstanding

balance. At December 31, 1995, $1.1 million of the deferred receivable is
included in accounts receivable--trade and $1.9 million is included in other
assets. The related interest income is included in other income in the income
statement. The advance from ENSERCH to fund the extraordinary reimbursable
maintenance expenses will not be needed for ongoing working capital and will
be repaid to ENSERCH when the receivable is collected by LSEPO. The deferred
receivable balances (both current and non-current) are offset by deferred
payable balances to ENSERCH of the same amounts. The interest expense in the
income statement represents the interest associated with the deferred payable
balances to ENSERCH.
 
4. RELATED PARTY TRANSACTIONS
 
  In the ordinary course of business, LSEPO engages in various transactions
with ENSERCH and its affiliates. LSEPO is charged for direct and indirect
costs incurred by LSEC, ENSERCH and other affiliates that are associated with
LSEPO's business and operations, including general and administrative costs
incurred in the management of operations and in performing accounting,
treasury, internal audit, income tax planning and compliance, legal,
information systems, human resources and other functions. Charges are
determined on a basis that reasonably reflects the actual costs of services
performed for LSEPO and may include allocations based on such factors as the
percentage of time spent on projects or services, the number of employees or
net capital employed. LSEPO believes that the methods used are reasonable and
that allocated costs approximate costs that would have been incurred if LSEPO
had operated as an unaffiliated entity. Charges from LSEC, ENSERCH and other
affiliates were $916, $955 and $817 for 1993, 1994 and 1995, respectively.
 
  ENSERCH advances cash to LSEPO to meet its working capital needs and LSEPO
remits any excess cash to ENSERCH. No interest is charged on these advances.
Immediately prior to the Merger, ENSERCH will make a capital contribution to
LSEPO, or LSEPO will make a distribution to ENSERCH, in an amount sufficient
to cause LSEPO's working capital to be $3.5 million. Following the Merger,
ENSERCH will no longer fund LSEPO's operations.
 
  LSEPO has entered into agreements to operate and maintain three cogeneration
plants, in each of which indirect wholly-owned subsidiaries of ENSERCH hold
the general partner's interest (see Notes 1 and 8).
 
  Pursuant to a contract entered into at closing of development, the ENSERCH
affiliate that developed the Bellingham cogeneration project receives an
annual operator surcharge fee of $4 million from Encogen Northwest, L.P. LSEPO
receives the payment and immediately remits it to the ENSERCH affiliate.
 
  LSEPO and the ENSERCH affiliate holding the general partner's interest in
the Bellingham plant share incentive fees (or penalties) resulting from the
availability of that plant. LSEPO's share is approximately one third, and the
ENSERCH affiliate's share is approximately two thirds. LSEPO collects the
incentive fees, retains its share and remits the remainder to the ENSERCH
affiliate. Incentive fees earned by LSEPO for the availability of the
Bellingham plant were $.2 million, $.4 million and $.6 million in 1993, 1994
and 1995, respectively.

5. INCOME TAXES
 
  LSEPO's operations are included in ENSERCH's consolidated federal income tax
return. LSEPO makes tax payments to ENSERCH on the basis of a separate federal
income tax return.

  At December 31, 1995 and 1994, LSEPO had a deferred tax asset of $4,
included in other assets, due to property-related differences in the financial
accounting basis and income tax basis of LSEPO's assets.
 
6. EMPLOYEE BENEFIT PLANS
 
  Substantially all personnel associated with LSEPO are covered by an ENSERCH
pension plan, and LSEPO receives an allocated portion of the plan expenses,
which is included in the amounts disclosed in Note 4. Medical, dental and
similar benefits are also provided under ENSERCH plans. In addition, ENSERCH
provides a voluntary contributory investment plan to substantially all
employees of LSEPO.
 
7. FINANCIAL INSTRUMENTS AND RISK MANAGEMENT
 
  The fair value of financial instruments, consisting primarily of cash,
accounts receivable and accounts payable, approximated carrying value at
December 31, 1995 and 1994.
 
8. MAJOR CUSTOMERS
 
  LSEPO derives all of its revenues from three limited partnerships, in each
of which an ENSERCH affiliate holds the general partner's interest (see Notes
1 and 4).
 
  The percentage of LSEPO's total revenues, excluding reimbursement of
expenses, from each of its three major customers is summarized below:

9. COMMITMENTS AND CONTINGENT LIABILITIES
 
  In the ordinary course of business, LSEPO is involved in certain legal
proceedings. In the opinion of management, LSEPO will incur no liability from

10. PRO FORMA SHARES OUTSTANDING (UNAUDITED)
 
  In connection with the proposed merger of ENSERCH with TUC Holding Company,
ENSERCH plans to merge the operations of LSEPO and Enserch Exploration, Inc.
("EEX"), a company approximately 83% owned by ENSERCH. LSEPO will be the
surviving corporation of that merger (the "Merger"), in which its name will be
changed to Enserch Exploration, Inc. ("New EEX"). In the Merger each
outstanding share of EEX Common Stock will be converted into one share of New
EEX Common Stock and the outstanding shares of LSEPO will be converted into a
number of shares of New EEX Common Stock determined by dividing $7.0 million
by the average of the closing sales prices of EEX Common Stock on the 15
trading days preceding the fifth trading day prior to the effective time of
the Merger. A market price of EEX shares of $9.00 was assumed to determine the
pro forma converted shares outstanding and to compute pro forma earnings per
share.
