              COMPETITIVE ADVANCE AND REVOLVING CREDIT FACILITY AGREEMENT (the
              "AGREEMENT"), dated as of March 2, 1998, among TEXAS UTILITIES
              COMPANY, a Texas corporation ("TUC"); TEXAS UTILITIES ELECTRIC
              COMPANY, a Texas corporation and a wholly owned subsidiary of TUC
              ("TU ELECTRIC"), and ENSERCH CORPORATION, a Texas corporation and
              a wholly owned subsidiary of TUC ("ENSERCH" and, together with
              TUC and TU Electric, the "BORROWERS", and each individually, a
              "BORROWER"); the lenders listed in Schedule 2.01 (together with
              their successors and assigns, the "LENDERS"); THE CHASE MANHATTAN
              BANK ("CHASE"), as Competitive Advance Facility Agent (in such
              capacity, the "CAF AGENT"); and CHASE BANK OF TEXAS, NATIONAL
              ASSOCIATION ("CHASE BANK OF TEXAS"), as administrative agent for
              the Lenders (in such capacity, the "ADMINISTRATIVE AGENT"; and,
              together with the CAF Agent, the "AGENTS").

       The Borrowers have requested the Lenders to extend credit in the form of
Standby Borrowings (such term and each other capitalized term used herein
having the meaning given it in Article I) to the Borrowers in an aggregate
principal amount at any time outstanding not in excess of $3,500,000,000.  The
Borrowers have also requested the Lenders to provide a procedure pursuant to
which the Borrowers may invite the Lenders to bid on an uncommitted basis on
short-term borrowings by the Borrowers.  Subject to the terms and conditions
set forth herein, the proceeds of any such borrowings are to be used (i) to
finance or refinance equity or subordinated loan advances from TUC to FinCo 1
and FinCo 2 in connection with the Acquisition and (i) to refinance the
Existing TUC Credit Agreements and for working capital and other corporate
purposes, including commercial paper back-up.  The Lenders are willing to
extend such credit to the Borrowers on the terms and subject to the conditions
herein set forth.

       Accordingly, the parties hereto agree as follows:

       SECTION 1.1.  DEFINED TERMS.  As used in this Agreement, the following
terms shall have the meanings specified below:

              "ABR BORROWING" shall mean a Borrowing comprised of ABR Loans.

              "ABR LOAN" shall mean any Standby Loan bearing interest at a rate
       determined by reference to the Alternate Base Rate in accordance with
       the provisions of Article II

       loan bearing interest at a rate determined by reference to the Alternate
       Base Rate.

              "ACQUISITION" shall mean the acquisition by Bidco of the Target
       Shares, whether pursuant to the Offer or pursuant to the procedures

       purchases (and includes where the context permits payments by Bidco to
       TEG's share option holders to purchase or cancel the benefit of such
       options).

              "ACQUISITION COMPANY" shall mean each of FinCo 1, FinCo 2 and
       Bidco.

              "ACQUISITION DATE" shall mean the date as of which a person or
       group of related persons first acquires more than 30% of the outstanding
       Voting Shares of TUC (within the meaning of Section 13(d) or 14(d) of
       the Securities Exchange Act of 1934, as amended, and the applicable
       rules and regulations thereunder).

              "ADMINISTRATIVE FEES" shall have the meaning assigned to such
       term in Section 2.05(b).

              "ADMINISTRATIVE QUESTIONNAIRE" shall mean an Administrative

       controlled by or is under common control with the person specified.

              "ALTERNATE BASE RATE" shall mean, for any day, a rate per annum
       (rounded upwards, if necessary, to the next 1/16 of 1%) equal to the
       greatest of (a) the Federal Funds Effective Rate in effect on such day
       plus  1/2 of 1%, (a) the Base CD Rate in effect on such day plus 1% and
       (a) the Prime Rate in effect on such day.  For purposes hereof, "PRIME
       RATE" shall mean the rate of interest per annum publicly announced from
       time to time by Chase as its prime rate in effect at its principal
       office in New York City; each change in the Prime Rate shall be
       effective on the date such change is publicly announced as effective;
       "BASE CD RATE" shall mean the sum of (a) the product of (i) the Three-
       Month Secondary CD Rate and (i) Statutory Reserves and (a) the
       Assessment Rate;  "THREE-MONTH SECONDARY CD RATE" shall mean, for any
       day, the secondary market rate for three-month certificates of deposit
       reported as being in effect on such day (or, if such day shall not be a
       Business Day, the next preceding Business Day) by the Board through the
       public information telephone line of the Federal Reserve Bank of New
       York (which rate will, under the current practices of the Board, be
       published in Federal Reserve Statistical Release H.15(519) during the
       week following such day), or, if such rate shall not be so reported on
       such day or such next preceding Business Day, the average of the
       secondary market quotations for three-month certificates of deposit of
       major money





                                      -2-

       center banks in New York City received at approximately 10:00 a.m., New
       York City time, on such day (or, if such day shall not be a Business
       Day, on the next preceding Business Day) by the CAF Agent from three New
       York City negotiable certificate of deposit dealers of recognized
       standing selected by it; "ASSESSMENT RATE" shall mean, for any day, the
       annual rate (rounded upwards to the next 1/100 of 1%) most recently
       estimated by Chase as the then current net annual assessment rate that
       will be employed in determining amounts payable by Chase to the Federal
       Deposit Insurance Corporation (or any successor) for insurance by such
       Corporation (or such successor) of time deposits made in US dollars at
       Chase's domestic offices; and "FEDERAL FUNDS EFFECTIVE RATE" shall mean,
       for any day, the weighted average of the rates on overnight Federal
       funds transactions with members of the Federal Reserve System arranged
       by Federal funds brokers, as released on the next succeeding Business
       Day by the Federal Reserve Bank of New York, or, if such rate is not so
       released for any day which is a Business Day, the arithmetic average
       (rounded upwards to the next 1/100th of 1%), as determined by Chase, of
       the quotations for the day of such transactions received by Chase from
       three Federal funds brokers of recognized standing selected by it.  If
       for any reason Chase shall have determined (which determination shall be
       conclusive absent manifest error; provided that Chase, shall, upon
       request, provide to the applicable Borrower a certificate setting forth
       in reasonable detail the basis for such determination) that it is unable
       to ascertain the Federal Funds Effective Rate for any reason, including
       the inability of Chase to obtain sufficient quotations in accordance
       with the terms thereof, the Alternate Base Rate shall be determined
       without regard to clause (a) of the first sentence of this definition
       until the circumstances giving rise to such inability no longer exist.
       Any change in the Alternate Base Rate due to a change in the Prime Rate
       or the Federal Funds Effective Rate shall be effective on the effective
       date of such change in the Prime Rate or the Federal Funds Effective
       Rate, respectively.

              "APPLICABLE MARGIN" shall mean, (i) on any date from the date
       hereof to and including the date six months hereafter, 0.0% for ABR
       Loans made to any Borrower, 1.05% per annum for Eurodollar Loans made to
       TUC, .85% per annum for Eurodollar Loans made to TU Electric and .85%
       per annum for Eurodollar Loans made to Enserch and (ii) on any date
       following the date six months following the date hereof with respect to
       any Borrower, the percentage per annum set forth in the column
       identified as Level 1, Level 2, Level 3 or  Level 4 below, based upon
       the Level corresponding to the lower Debt Rating of such Borrower at the
       time of determination, provided, that the Applicable Margins set forth
       below with respect to each Level shall be increased by .50% with respect
       to Eurodollar Loans outstanding at any time following the Revolving
       Period, provided, further, that, the Applicable Margin with respect to
       ABR Loans outstanding at any time following the Revolving Period shall
       be equal to, for each Level, the then-effective Applicable Margin for
       Eurodollar Loans less 1.00% (but not negative).  Any change in the
       Applicable Margin shall be effective on the date on which the applicable
       rating agency announces any change in the Debt Rating.

       established under Section 4201 of ERISA as a result of a complete or
       partial withdrawal from a Multiemployer Plan, as such terms are defined
       in Part I of Subtitle E of Title IV of ERISA.

       SECTION 1.2.  TERMS GENERALLY.  The definitions in Section 1.01 shall
apply equally to both the singular and plural forms of the terms defined.
Whenever the context may require, any pronoun shall include the corresponding
masculine, feminine and neuter forms.  The words "include," "includes" and
"including" shall be deemed to be followed by the phrase "without limitation."
All references herein to Articles, Sections, Exhibits and Schedules shall be
deemed references to Articles and Sections of, and Exhibits and Schedules to,
this Agreement unless the context shall otherwise require.  Except as otherwise

                                   ARTICLE II
                                  THE CREDITS

       SECTION 2.1.  COMMITMENTS.  Subject to the terms and conditions and
relying upon the representations and warranties herein set forth, each Lender
agrees, severally and not jointly, to make Standby Loans, at any time and from
time to time until the earlier of the Maturity Date and the termination of the
Commitment of such Lender, to each Borrower in an aggregate principal amount at
any time outstanding not to exceed such Lender's Commitment minus the amount by
which the Competitive Loans made to any Borrower and outstanding at such time
shall be deemed to have used such Commitment pursuant to Section 2.14, subject,
however, to the conditions that (i) at no time shall the sum of (x) the
outstanding aggregate principal amount of all Standby Loans plus (y) the
outstanding aggregate principal amount of all Competitive Loans exceed the
Total Commitment, (i) Offer Loans shall be made solely to TUC and in no





                                      -20-
<PAGE>   25
more than ten Borrowings that would, after giving effect to any such Borrowing,
increase the principal amount of Loans outstanding, (i) at no time shall the
sum of (x) the outstanding aggregate principal amount of Offer Loans plus (y)
the outstanding aggregate principal amount of General Loans used for purposes
described in Sections 5.08(ii)(A), (C) and (E) and Loans under and as defined
in the Facility B Credit Agreement used for purposes described in Section
5.08(ii) exceed $2,930,000,000, (i) at no time shall the sum of (x) the
outstanding aggregate principal amount of all Loans made to Enserch plus (y)
the outstanding aggregate principal amount of all Loans under and as defined in
the Facility B Credit Agreement made to Enserch exceed $650,000,000, (i) unless
and until the TU Electric Approval Date shall have occurred, at no time shall
the sum of (x) the outstanding aggregate principal amount of all Loans made to
TU Electric plus (y) the outstanding aggregate principal amount of all Loans
under and as defined in the Facility B Credit Agreement made to TU Electric
exceed $1,250,000,000, (i) at no time shall the outstanding aggregate principal
amount of all Standby Loans made by any Lender exceed the amount of such
Lender's Commitment and (i) at all times, the outstanding aggregate principal
amount of all Standby Loans made by each Lender to each Borrower shall equal
the product of (B) the percentage which such Lender's Commitment represents of
the Total Commitment times (B) the outstanding aggregate principal amount of
all Standby Loans made to such Borrower.

       Within the foregoing limits, the Borrowers may borrow, pay or prepay
and, subject to the limitations set forth in Section 2.11(a), reborrow Standby
Loans hereunder, on and after the Effective Date and prior to the Maturity
Date, subject to the terms, conditions and limitations set forth herein.

       SECTION 2.2.  LOANS.  (a)  Each Standby Loan shall be made as part of a
Borrowing consisting of Loans made by the Lenders ratably in accordance with
their respective Commitments; provided, however, that the failure of any Lender
to make any Standby Loan shall not in itself relieve any other Lender of its
obligation to lend hereunder (it being understood, however, that no Lender
shall be responsible for the failure of any other Lender to make any Loan
required to be made by such other Lender).  Each Competitive Loan shall be made
in accordance with the procedures set forth in Section 2.03.  The Standby Loans
or Competitive Loans comprising any Borrowing shall be (i) in the case of
Competitive Loans, in an aggregate principal amount which is an integral
multiple of $1,000,000 and not less than $5,000,000 and (i) in the case of
Standby Loans, in an aggregate principal amount which is an integral multiple
of $5,000,000 and not less than $25,000,000 (or an aggregate principal amount
equal to the remaining balance of the available Commitments).

       (b)    Each Competitive Borrowing shall be comprised entirely of
Eurodollar Competitive Loans or Fixed Rate Loans, and each Standby Borrowing
shall be comprised entirely of Eurodollar Standby Loans or ABR Loans, as the
Borrower may request pursuant to Section 2.03 or 2.04, as applicable. Each
Lender may at its option make any Eurodollar Loan by causing any domestic or
foreign branch or Affiliate of such Lender to make such Loan; provided that any
exercise of such option shall not affect the obligation of the Borrower to
repay





                                      -21-
<PAGE>   26
such Loan in accordance with the terms of this Agreement.  Borrowings of more
than one Type may be outstanding at the same time.

       (c)    Subject to paragraph (d) below, each Lender shall make each Loan
to be made by it hereunder on the proposed date thereof by wire transfer of
immediately available funds to the Administrative Agent in Houston, Texas, not
later than noon, Houston time, and the Administrative Agent shall by 2:00 p.m.,
Houston time, credit the amounts so received to the account or accounts
specified from time to time in one or more notices delivered by the applicable
Borrower to the Administrative Agent or, if a Borrowing shall not occur on such
date because any condition precedent herein specified shall not have been met,
return the amounts so received to the respective Lenders.  Competitive Loans
shall be made by the Lender or Lenders whose Competitive Bids therefor are
accepted pursuant to Section 2.03 in the amounts so accepted.  Standby Loans
shall be made by the Lenders pro rata in accordance with Section 2.14.  Unless
the Administrative Agent shall have received notice from a Lender prior to the
date of any Borrowing that such Lender will not make available to the
Administrative Agent such Lender's portion of such Borrowing, the
Administrative Agent may assume that such Lender has made such portion
available to the Administrative Agent on the date of such Borrowing in
accordance with this paragraph (c) and the Administrative Agent may, in
reliance upon such assumption, make available to the Borrower on such date a
corresponding amount.  If and to the extent that such Lender shall not have
made such portion available to the Administrative Agent, such Lender and such
Borrower (without waiving any claim against such Lender for such Lender's
failure to make such portion available) severally agree to repay to the
Administrative Agent forthwith on demand such corresponding amount together
with interest thereon, for each day from the date such amount is made available
to the Borrower until the date such amount is repaid to the Administrative
Agent at (i) in the case of the Borrower, the interest rate applicable at the
time to the Loans comprising such Borrowing and (i) in the case of such Lender,
the Federal Funds Effective Rate.  If such Lender shall repay to the
Administrative Agent such corresponding amount, such amount shall constitute
such Lender's Loan as part of such Borrowing for purposes of this Agreement.

       (d)    A Borrower may refinance all or any part of any Standby Borrowing
with a Standby Borrowing of the same or a different Type, subject to the
conditions and limitations set forth in this Agreement.  Any Standby Borrowing
or part thereof so refinanced shall be deemed to be repaid or prepaid in
accordance with Section 2.06 or 2.11, as applicable, with the proceeds of a new
Standby Borrowing, and the proceeds of the new Standby Borrowing, to the extent
they do not exceed the principal amount of the Standby Borrowing being
refinanced, shall not be paid by the Lenders to the Administrative Agent or by
the Administrative Agent to such Borrower pursuant to paragraph (c) above.

       SECTION 2.3.  COMPETITIVE BID PROCEDURE.  (a)  In order to request
Competitive Bids, a Borrower shall hand deliver or telecopy to the CAF Agent a
duly completed Competitive Bid Request in the form of Exhibit A-1 hereto, to be
received by the CAF Agent (i) in the case of a Eurodollar Competitive
Borrowing, not later than 11:00 a.m., New York City time, four





                                      -22-
<PAGE>   27
Business Days before a proposed Competitive Borrowing and (i) in the case of a
Fixed Rate Borrowing, not later than 11:00 a.m., New York City time, one
Business Day before a proposed Competitive Borrowing.  No ABR Loan shall be
requested in, or made pursuant to, a Competitive Bid Request.  A Competitive
Bid Request that does not conform substantially to the format of Exhibit A-1
may be rejected in the CAF Agent's sole discretion, and the CAF Agent shall
promptly notify the Borrower of such rejection by telecopy.  Each Competitive
Bid Request shall refer to this Agreement and specify (w) whether the Borrowing
then being requested is to be a Eurodollar Borrowing or a Fixed Rate Borrowing,
(x) the date of such Borrowing (which shall be a Business Day) and the
aggregate principal amount thereof which shall be in a minimum principal amount
of $5,000,000 and in an integral multiple of $1,000,000, and (y) the Interest
Period with respect thereto (which may not end after the Maturity Date).
Promptly after its receipt of a Competitive Bid Request that is not rejected as
aforesaid, the CAF Agent shall telecopy to each Lender a Notice of Competitive
Bid Request in the form of Exhibit A-2 inviting the Lenders to bid, on the
terms and conditions of this Agreement, to make Competitive Loans.

       (b)    Each Lender invited to bid may, in its sole discretion, make one
or more Competitive Bids to the Borrower responsive to such Borrower's
Competitive Bid Request.  Each Competitive Bid by a Lender must be received by
the CAF Agent by telecopy, in the form of Exhibit A-3 hereto, (i) in the case
of a Eurodollar Competitive Borrowing, not later than 9:30 a.m., New York City
time, three Business Days before a proposed Competitive Borrowing and (i) in
the case of a Fixed Rate Borrowing, not later than 9:30 a.m., New York City
time, on the day of a proposed Competitive Borrowing.  Multiple bids will be
accepted by the CAF Agent.  Competitive Bids that do not conform substantially
to the format of Exhibit A-3 may be rejected by the CAF Agent, and the CAF
Agent shall notify the Lender making such nonconforming bid of such rejection
as soon as practicable.  Each Competitive Bid shall refer to this Agreement and
specify (x) the principal amount (which shall be in a minimum principal amount
of $5,000,000 and in an integral multiple of $1,000,000 and which may equal the
entire principal amount of the Competitive Borrowing requested by the
applicable Borrower) of the Competitive Loan or Loans that the Lender is
willing to make to such Borrower, (y) the Competitive Bid Rate or Rates at
which the Lender is prepared to make the Competitive Loan or Loans and (z) the
Interest Period and the last day thereof.  If any Lender invited to bid shall
elect not to make a Competitive Bid, such Lender shall so notify the CAF Agent
by telecopy (I) in the case of Eurodollar Competitive Loans, not later than
9:30 a.m., New York City time, three Business Days before a proposed
Competitive Borrowing, and (II) in the case of Fixed Rate Loans, not later than
9:30 a.m., New York City time, on the day of a proposed Competitive Borrowing;
provided, however, that failure by any Lender to give such notice shall not
cause such Lender to be obligated to make any Competitive Loan as part of such
Competitive Borrowing.  A Competitive Bid submitted by a Lender pursuant to
this paragraph (b) shall be irrevocable.

       (c)    The CAF Agent shall notify the Borrower by telecopy, of all the
Competitive Bids made, the Competitive Bid Rate and the principal amount of
each Competitive Loan in respect of which such Competitive Bid was made and the
identity of the Lender that made each such bid





                                      -23-
<PAGE>   28
by (i) in the case of a Eurodollar Competitive Borrowing, not later than 10:00
a.m., New York City time, three Business Days before a proposed Competitive
Borrowing and (i) in the case of a Fixed Rate Borrowing, not later than 10:00
a.m., New York City time, on the day of a proposed Competitive Borrowing.  The
CAF Agent shall send a copy of all Competitive Bids to the Borrower for its
records as soon as practicable after the completion of the bidding process set
forth in this Section 2.03.

       (d)    A Borrower may in its sole and absolute discretion, subject only
to the provisions of this paragraph (d), accept or reject any or all
Competitive Bids referred to in paragraph (c) above.  Such Borrower shall
notify the CAF Agent by telephone, confirmed by telecopy in the form of a
Competitive Bid Accept/Reject Letter, whether and to what extent it has decided
to accept or reject any of or all the bids referred to in paragraph (c) above
by (i) in the case of a Eurodollar Competitive Borrowing, not later than 10:30
a.m., New York City time, three Business Days before a proposed Competitive
Borrowing and (i) in the case of a Fixed Rate Borrowing, not later than 10:30
a.m., New York City time, on the day of a proposed Competitive Borrowing;
provided, however, that (i) the failure by such Borrower to give such notice
shall be deemed to be a rejection of all the bids referred to in paragraph (c)
above, (i) such Borrower shall not accept a bid made at a particular
Competitive Bid Rate if it has decided to reject a bid made at a lower
Competitive Bid Rate, (i) the aggregate amount of the Competitive Bids accepted
by such Borrower shall not exceed the principal amount specified in the
Competitive Bid Request, (i) if such Borrower shall accept a bid or bids made
at a particular Competitive Bid Rate but the amount of such bid or bids shall
cause the total amount of bids to be accepted by such Borrower to exceed the
amount specified in the Competitive Bid Request, then such Borrower shall
accept a portion of such bid or bids in an amount equal to the amount specified
in the Competitive Bid Request less the amount of all other Competitive Bids
accepted with respect to such Competitive Bid Request, which acceptance, in the
case of multiple bids at such Competitive Bid Rate, shall be made pro rata in
accordance with the amount of each such bid at such Competitive Bid Rate, and
(i) except pursuant to clause (iv) above, no bid shall be accepted for a
Competitive Loan unless such Competitive Loan is in a minimum principal amount
of $5,000,000 and an integral multiple of $1,000,000; provided further,
however, that if a Competitive Loan must be in an amount less than $5,000,000
because of the provisions of clause (iv) above, such Competitive Loan may be
for a minimum of $1,000,000 or any integral multiple thereof, and in
calculating the pro rata allocation of acceptances of portions of multiple bids
at a particular Competitive Bid Rate pursuant to clause (iv) the amounts shall
be rounded to integral multiples of $1,000,000 in a manner which shall be in
the discretion of the applicable Borrower.  A notice given by a Borrower
pursuant to this paragraph (d) shall be irrevocable.

       (e)    The CAF Agent shall promptly notify each bidding Lender (and the
Administrative Agent), by telecopy, whether or not its Competitive Bid has been
accepted (and if so, in what amount and at what Competitive Bid Rate) and each
successful bidder will thereupon become bound, subject to the other applicable
conditions hereof, to make the Competitive Loan in respect of which its bid has
been accepted.





                                      -24-
<PAGE>   29
       (f)    No Competitive Borrowing shall be requested or made hereunder if
after giving effect thereto any of the conditions set forth in clauses (i)
through (iv) of Section 2.01 would not be met.

       (g)    If either the Administrative Agent or CAF Agent shall elect to
submit a Competitive Bid in its capacity as a Lender, such party shall submit
such bid directly to the Borrower one quarter of an hour earlier than the
latest time at which the other Lenders are required to submit their bids to the
CAF Agent pursuant to paragraph (b) above.

       (h)    Each of the Borrowers and the CAF Agent shall deliver to the
Administrative Agent by telecopy copies of all notices delivered by it pursuant
to this Section 2.03 at the same times such notices are delivered hereunder.
All notices required by this Section 2.03 shall be given in accordance with
Section 8.01.

       (i)    A Competitive Bid Request shall not be made within five Business
Days after the date of any previous Competitive Bid which was accepted by a
Borrower pursuant to paragraph (d) above.

       SECTION 2.4.  STANDBY BORROWING PROCEDURE.  In order to request a
Standby Borrowing, a Borrower shall hand deliver or telecopy to the
Administrative Agent a duly completed Standby Borrowing Request in the form of
Exhibit A-5 (a) in the case of a Eurodollar Standby Borrowing, not later than
10:00 a.m., Houston time, three Business Days before such Borrowing, and (a) in
the case of an ABR Borrowing, not later than 10:00 a.m., Houston time, one
Business Day before such Borrowing.  No Fixed Rate Loan shall be requested or
made pursuant to a Standby Borrowing Request.  Such notice shall be irrevocable
and shall in each case specify (i) whether the Borrowing then being requested
is to be a Eurodollar Standby Borrowing or an ABR Borrowing; (i) the date of
such Standby Borrowing (which shall be a Business Day) and the amount thereof;
and (i) if such Borrowing is to be a Eurodollar Standby Borrowing, the Interest
Period with respect thereto, which shall not end after the Maturity Date.  If
no election as to the Type of Standby Borrowing is specified in any such
notice, then the requested Standby Borrowing shall be an ABR Borrowing.  If no
Interest Period with respect to any Eurodollar Standby Borrowing is specified
in any such notice, then the Borrower shall be deemed to have selected an
Interest Period of one month's duration (subject, at all times prior to
completion of syndication of the Total Commitment, to the limitations set forth
in the definition of "Interest Period").  If a Borrower shall not have given
notice in accordance with this Section 2.04 of its election to refinance a
Standby Borrowing prior to the end of the Interest Period in effect for such
Borrowing, then such Borrower shall (unless such Borrowing is repaid at the end
of such Interest Period) be deemed to have given notice of an election to
refinance such Borrowing with an ABR Borrowing.  Notwithstanding any other
provision of this Agreement to the contrary, no Standby Borrowing shall be
requested if the Interest Period with respect thereto would end after the
Maturity Date.  The Administrative Agent shall promptly advise the Lenders of
any notice given pursuant to this Section 2.04 and of each Lender's portion of
the requested Borrowing.

       SECTION 2.5.  FEES.  (a)  Each Borrower agrees jointly and severally to
pay to each Lender, through the Administrative Agent, on each March 31, June
30, September 30 and December 31 (with the first payment being due on March 31,
1998) and on each date on which the Commitment of such Lender shall be
terminated as provided herein, a facility fee (a "FACILITY FEE"), at a rate per
annum equal to the Facility Fee Percentage from time to time in effect on the
amount of the sum of the unused Commitment of such Lender plus the principal
amount of Loans outstanding made by such Lender (without regard, in either
case, to any Competitive Loans made by any Lender), during the preceding
quarter (or other period commencing on the Effective Date or ending with the
Maturity Date or any date on which the Commitment of such Lender shall be
terminated).  All Facility Fees shall be computed on the basis of the actual
number of days elapsed in a year of 365 or 366 days, as the case may be.  The
Facility Fee due to each Lender shall commence to accrue on the Effective Date,
and shall cease to accrue on the earlier of the Maturity Date and the
termination of the Commitment of such Lender as provided herein.

       (b)    Each Borrower agrees jointly and severally to pay the
Administrative Agent, for its own account, the administrative fees provided for
in the Agent Fee Letter referred to in the Letter Agreement (the
"ADMINISTRATIVE FEES").

       (c)    Each Borrower agrees to pay the CAF Agent, for its own account,
the Auction Fees applicable to such Borrower.

       (d)    All Fees shall be paid on the dates due, in immediately available
funds, to the Administrative Agent for distribution, if and as appropriate,
among the Lenders, the Initial Underwriters or the Joint Lead Arrangers or to
the CAF Agent.  Once paid, none of the Fees shall be refundable under any
circumstances.

       SECTION 2.6.  REPAYMENT OF LOANS; EVIDENCE OF INDEBTEDNESS.  (a)  The
outstanding principal balance of each Loan shall be due and payable on the last
day of the Interest Period applicable thereto and on the Maturity Date.

       (b)    Each Lender shall maintain in accordance with its usual practice
an account or accounts evidencing the indebtedness to such Lender resulting
from each Loan made by such Lender from time to time, including the amounts of
principal and interest payable and paid to such Lender from time to time under
this Agreement.

       (c)    The Administrative Agent shall maintain accounts in which it will
record (i) the amount of each Loan made hereunder, the Type of each Loan made
and the Interest Period applicable thereto, (i) the amount of any principal or
interest due and payable or to become due and payable from each Borrower to
each Lender hereunder and (i) the amount of any sum received by the
Administrative Agent hereunder from each Borrower and each Lender's share
thereof.





                                      -26-
<PAGE>   31
       (d)    The entries made in the accounts maintained pursuant to
paragraphs (b) and (c) of this Section 2.06 shall, to the extent permitted by
applicable law, be prima facie evidence of the existence and amounts of the
obligations therein recorded; provided, however, that the failure of any Lender
or the Administrative Agent to maintain such accounts or any error therein
shall not in any manner affect the obligations of the Borrowers to repay the
Loans in accordance with their terms.

       SECTION 2.7.  INTEREST ON LOANS.  (a)  Subject to the provisions of
Section 2.08, the Loans comprising each Eurodollar Borrowing shall bear
interest (computed on the basis of the actual number of days elapsed over a
year of 360 days) at a rate per annum equal to the LIBO Rate for the Interest
Period in effect for such Borrowing plus the Applicable Margin from time to
time in effect and in the case of each Eurodollar Competitive Loan, the LIBO
Rate for the Interest Period in effect for such Borrowing plus the Competitive
Bid Margin offered by the Lender making such Loan and accepted by the
applicable Borrower pursuant to Section 2.03.

       (b)    Subject to the provisions of Section 2.08, the Loans comprising
each ABR Borrowing shall bear interest (computed on the basis of the actual
number of days elapsed over a year of 365 or 366 days, as the case may be, for
periods during which the Alternate Base Rate is determined by reference to the
Prime Rate and 360 days for other periods) at a rate per annum equal to the
Alternate Base Rate plus the Applicable Margin from time to time in effect.

       (c)    Subject to the provisions of Section 2.08, each Fixed Rate Loan
shall bear interest at a rate per annum (computed on the basis of the actual
number of days elapsed over a year of 360 days) equal to the fixed rate of
interest offered by the Lender making such Loan and accepted by the Borrower
pursuant to Section 2.03.

       (d)    Interest on each Loan shall be payable on each Interest Payment
Date applicable to such Loan except as otherwise provided in this Agreement.
The applicable LIBO Rate or Alternate Base Rate for each Interest Period or day
within an Interest Period, as the case may be, shall be determined by Chase,
and such determination shall be conclusive absent manifest error; provided that
Chase shall, upon request, provide to the applicable Borrower a certificate
setting forth in reasonable detail the basis for such determination.

       SECTION 2.8.  DEFAULT INTEREST.  If a Borrower shall default in the
payment of the principal of or interest on any Loan or any other amount
becoming due hereunder, whether by scheduled maturity, notice of prepayment,
acceleration or otherwise, such Borrower shall on demand from time to time from
the Administrative Agents pay interest, to the extent permitted by law, on such
defaulted amount up to (but not including) the date of actual payment (after as
well as before judgment) at a rate per annum (computed as provided in Section
2.07(b)) equal to the Alternate Base Rate plus the Applicable Margin for ABR
Loans plus 1%.





                                      -27-
<PAGE>   32
       SECTION 2.9.  ALTERNATE RATE OF INTEREST.  In the event, and on each
occasion, that on the day two Business Days prior to the commencement of any
Interest Period for a Eurodollar Borrowing the Administrative Agent shall have
determined (i) that dollar deposits in the principal amounts of the Eurodollar
Loans comprising such Borrowing are not generally available in the London
interbank market or (i) that reasonable means do not exist for ascertaining the
LIBO Rate, the Administrative Agent shall, as soon as practicable thereafter,
give telecopy notice of such determination to the Borrowers and the Lenders.
In the event of any such determination under clauses (i) or (ii) above, until
the Administrative Agent shall have advised the Borrowers and the Lenders that
the circumstances giving rise to such notice no longer exist, (x) any request
by a Borrower for a Eurodollar Competitive Borrowing pursuant to Section 2.03
shall be of no force and effect and shall be denied by the Administrative Agent
and (y) any request by a Borrower for a Eurodollar Standby Borrowing pursuant
to Section 2.04 shall be deemed to be a request for an ABR Borrowing.  In the
event the Required Lenders notify the Administrative Agent that the rates at
which dollar deposits are being offered will not adequately and fairly reflect
the cost to such Lenders of making or maintaining Eurodollar Loans during such
Interest Period, the Administrative Agent shall notify the applicable Borrower
of such notice and until the Required Lenders shall have advised the
Administrative Agent that the circumstances giving rise to such notice no
longer exist, any request by such Borrower for a Eurodollar Standby Borrowing
shall be deemed a request for an ABR Borrowing.  Each determination by the
Administrative Agent hereunder shall be made in good faith and shall be
conclusive absent manifest error; provided that the Administrative Agent,
shall, upon request, provide to the applicable Borrower a certificate setting
forth in reasonable detail the basis for such determination.

       SECTION 2.10.  TERMINATION AND REDUCTION OF COMMITMENTS.  (a)  The
Commitments shall be automatically terminated on the Maturity Date.  In
addition, until such time as the Equity Event shall have occurred, the Offer
Loan Commitments shall be automatically reduced by an amount equal to the net
proceeds of any issuance or disposition or any payment to TUC, in each case
described in Section 2.11(d), with such reduction to be effective on the later
to occur of the date of such issuance, sale or payment, as the case may be, and
the date specified under Section 2.11(d) for any related prepayment or
repayment of the Offer Loans.

       (b)    Upon (i) the date of the withdrawal or lapse of the Offer and (i)
28 days after the Effective Date if the Offer has not yet been posted, the
unused Offer Loan Commitments shall be automatically terminated.

       (c)    Upon at least two Business Days' prior irrevocable written notice
to the Administrative Agent, the Borrowers, acting jointly, may at any time in
whole permanently terminate, or from time to time in part permanently reduce,
the Offer Loan Commitments or the General Loan Commitments; provided, however,
that (i) each partial reduction of the Commitments shall be in an integral
multiple of $10,000,000 and in a minimum principal amount of $10,000,000 and
(i) no such termination or reduction shall be made that would reduce the Total
Commitment to an amount (1) less than the aggregate outstanding principal
amount of





                                      -28-
<PAGE>   33
all Competitive Loans or (1) less than $50,000,000, unless the result of such
termination or reduction referred to in this clause (2) is to reduce the Total
Commitment to $0.  The Administrative Agent shall advise the Lenders of any
notice given pursuant to this Section 2.10(c) and of each Lender's portion of
any such termination or reduction of the Total Commitment.

       (d)    If the Borrowers shall make the Term Election, then on the last
day of the Revolving Period the Total Commitment shall be permanently reduced
to an amount equal to the aggregate principal amount of Loans then outstanding.

       (e)    Each reduction in the Total Commitment hereunder shall be made
ratably among the Lenders in accordance with their respective Commitments.  The
Borrowers shall pay to the Administrative Agent for the account of the Lenders,
on the date of each termination or reduction of the Total Commitment, the
Facility Fees on the amount of the Commitments so terminated or reduced accrued
through the date of such termination or reduction.

       SECTION 2.11.  PREPAYMENT.  (a)  Each Borrower shall have the right at
any time and from time to time to prepay any Standby Borrowing, in whole or in
part, upon giving telecopy notice (or telephone notice promptly confirmed by
telecopy) to the Administrative Agent:  (i) before 10:00 a.m., Houston time,
three Business Days prior to prepayment, in the case of Eurodollar Loans, and
(i) before 10:00 a.m., Houston time, one Business Day prior to prepayment, in
the case of ABR Loans; provided, however, that each partial prepayment shall be
in an amount which is an integral multiple of $10,000,000 and not less than
$10,000,000.  No prepayment may be made in respect of any Competitive
Borrowing.  Any (i) principal amount of any Offer Loan repaid or prepaid at any
time and not refinanced on the date of such repayment or prepayment (as the
case may be) with the proceeds of another Offer Loan and (ii) any principal
amount of any Loan repaid or prepaid or on or after the last day of the
Revolving Period may not, in either case, be reborrowed.

       (b)    On the date of any termination or reduction of the Commitments
pursuant to Section 2.10, the Borrowers shall pay or prepay so much of the
Standby Borrowings as shall be necessary in order that the aggregate principal
amount of the Competitive Loans and Standby Loans outstanding will not exceed
the Total Commitment, after giving effect to such termination or reduction.

       (c)    Each notice of prepayment shall specify the prepayment date and
the principal amount of each Borrowing (or portion thereof) to be prepaid,
shall be irrevocable and shall commit the Borrower to prepay such Borrowing (or
portion thereof) by the amount stated therein on the date stated therein.  All
prepayments under this Section 2.11 shall be subject to Section 8.05 but
otherwise without premium or penalty.  All prepayments under this Section 2.11
shall be accompanied by accrued interest on the principal amount being prepaid
to the date of payment.

       (d)    Until such time as the Equity Event shall have occurred, upon (i)
the issuance by TUC (or any special purpose financing Subsidiary of TUC, other
than FinCo 1, FinCo 2 or any Subsidiary of FinCo 1 or of FinCo 2) of any debt,
equity or other capital market instruments or other securities (other than
stock of TUC issued in connection with employee stock option and other stock
purchase and incentive plans in effect on the date hereof), (i) the disposition
by TUC of any of the capital shares of FinCo 1, FinCo 2 or Enserch, or (i) the
payment by any Acquisition Company to TUC of any amount in respect of shares of
TUC exchanged for Target Shares, TUC shall prepay the principal amount of Offer
Loans hereunder in an amount equal to the net proceeds of such issuance or
disposition or such payment, as the case may be, with such prepayment to be
accompanied by payment of accrued interest on such Offer Loans being prepaid to
the date of payment and any amounts payable pursuant to Section 8.05.  Any
amounts required to be applied to the prepayment of Offer Loans shall be
applied as follows:  first, to the immediate prepayment of ABR Loans
outstanding, second, to the prepayment of Eurodollar Loans (not constituting
Competitive Loans) outstanding on the last day of the respective Interest
Periods for such Eurodollar Loans in the order that they occur, and third, to
the repayment of Competitive Loans, on the last day of the respective Interest
Periods for such Competitive Loans in the order that they occur.

       SECTION 2.12.  RESERVE REQUIREMENTS; CHANGE IN CIRCUMSTANCES.  (a)
Notwithstanding any other provision herein, if after the date of this Agreement
any change in applicable law or regulation or in the interpretation or
administration thereof by any Governmental Authority charged with the
interpretation or administration thereof (whether or not having the force of
law) shall change the basis of taxation of payments to any Lender hereunder
(except for changes in respect of taxes on the overall net income of such
Lender or its lending office imposed by the jurisdiction in which such Lender's
principal executive office or lending office is located), or shall result in
the imposition, modification or applicability of any reserve, special deposit
or similar requirement against assets of, deposits with or for the account of
or credit extended by any Lender, or shall result in the imposition on any
Lender or the London interbank market of any other condition affecting this
Agreement, such Lender's Commitment or any Eurodollar Loan or Fixed Rate Loan
made by such Lender, and the result of any of the foregoing shall be to
increase the cost to such Lender of making or maintaining any Eurodollar Loan
or Fixed Rate Loan or to reduce the amount of any sum received or receivable by
such Lender hereunder (whether of principal, interest or otherwise) by an
amount deemed by such Lender to be material, then the applicable Borrower or,
if the foregoing circumstances do not relate to a particular Borrowing, the
Borrowers shall, upon receipt of the notice and certificate provided for in
Section 2.12(c), promptly pay to such Lender such additional amount or amounts
as will compensate such Lender for such additional costs incurred or reduction
suffered.  Notwithstanding the foregoing, no Lender shall be entitled to
request compensation under this paragraph with respect to any Competitive Loan
if the change giving rise to such request was applicable to such Lender at the
time of submission of the Competitive Bid pursuant to which such Competitive
Loan was made.

<PAGE>   35
       (b)    If any Lender shall have determined that the adoption of any law,
rule, regulation or guideline arising out of the July 1988 report of the Basle
Committee on Banking Regulations and Supervisory Practices entitled
"International Convergence of Capital Measurement and Capital Standards," or
the adoption after the date hereof of any other law, rule, regulation or
guideline regarding capital adequacy, or any change in any of the foregoing or
in the interpretation or administration of any of the foregoing by any
Governmental Authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by any Lender (or any
lending office of such Lender) or any Lender's holding company with any request
or directive regarding capital adequacy (whether or not having the force of
law) of any such authority, central bank or comparable agency, has or would
have the effect of reducing the rate of return on such Lender's capital or on
the capital of such Lender's holding company, if any, as a consequence of this
Agreement, such Lender's Commitment or the Loans made by such Lender pursuant
hereto to a level below that which such Lender or such Lender's holding company
could have achieved but for such adoption, change or compliance (taking into
consideration such Lender's policies and the policies of such Lender's holding
company with respect to capital adequacy) by an amount deemed by such Lender to
be material, then from time to time such additional amount or amounts as will
compensate such Lender for any such reduction suffered will be paid by the
Borrowers to such Lender.  It is acknowledged that this Agreement is being
entered into by the Lenders on the understanding that the Lenders will not be
required to maintain capital against their Commitments under currently
applicable laws, regulations and regulatory guidelines.  In the event the
Lenders shall otherwise determine that such understanding is incorrect, it is
agreed that the Lenders will be entitled to make claims under this paragraph
(b) based upon market requirements prevailing on the date hereof for
commitments under comparable credit facilities against which capital is
required to be maintained.

       (c)    A certificate of each Lender setting forth such amount or amounts
as shall be necessary to compensate such Lender or its holding company as
specified in paragraph (a) or (b) above, as the case may be, and containing an
explanation in reasonable detail of the manner in which such amount or amounts
shall have been determined, shall be delivered to the applicable Borrower or
the Borrowers, as the case may be, and shall be conclusive absent manifest
error.  The Borrowers shall pay each Lender the amount shown as due on any such
certificate delivered by it within 10 days after its receipt of the same.  Each
Lender shall give prompt notice to the applicable Borrower of any event of
which it has knowledge, occurring after the date hereof, that it has determined
will require compensation by such Borrower pursuant to this Section; provided,
however, that failure by such Lender to give such notice shall not constitute a
waiver of such Lender's right to demand compensation hereunder.

       (d)    Failure on the part of any Lender to demand compensation for any
increased costs or reduction in amounts received or receivable or reduction in
return on capital with respect to any period shall not constitute a waiver of
such Lender's right to demand compensation with respect to such period or any
other period; provided, however, that no Lender shall be entitled to
compensation under this Section 2.12 for any costs incurred or reductions
suffered with





                                      -31-
<PAGE>   36
respect to any date unless it shall have notified the applicable Borrower that
it will demand compensation for such costs or reductions under paragraph (c)
above not more than 90 days after the later of (i) such date and (i) the date
on which it shall have become aware of such costs or reductions.  The
protection of this Section shall be available to each Lender regardless of any
possible contention of the invalidity or inapplicability of the law, rule,
regulation, guideline or other change or condition which shall have occurred or
been imposed.

       (e)    Each Lender agrees that it will designate a different lending
office if such designation will avoid the need for, or reduce the amount of,
such compensation and will not, in the reasonable judgment of such Lender, be
disadvantageous to such Lender.

       SECTION 2.13.  CHANGE IN LEGALITY.  (a)  Notwithstanding any other
provision herein, if any change in any law or regulation or in the
interpretation thereof by any Governmental Authority charged with the
administration or interpretation thereof shall make it unlawful for any Lender
to make or maintain any Eurodollar Loan or to give effect to its obligations as
contemplated hereby with respect to any Eurodollar Loan, then, by written
notice to the Borrowers and to the Agents, such Lender may:

              (i)    declare that Eurodollar Loans will not thereafter be made
       by such Lender hereunder, whereupon such Lender shall not submit a
       Competitive Bid in response to a request for Eurodollar Competitive
       Loans and any request for a Eurodollar Standby Borrowing shall, as to
       such Lender only, be deemed a request for an ABR Loan unless such
       declaration shall be subsequently withdrawn (any Lender delivering such
       a declaration hereby agreeing to withdraw such declaration promptly upon
       determining that such event of illegality no longer exists); and

              (ii)   require that all outstanding Eurodollar Loans made by it
       be converted to ABR Loans, in which event all such Eurodollar Loans
       shall be automatically converted to ABR Loans as of the effective date
       of such notice as provided in paragraph (b) below.

In the event any Lender shall exercise its rights under (i) or (ii) above, all
payments and prepayments of principal which would otherwise have been applied
to repay the Eurodollar Loans that would have been made by such Lender or the
converted Eurodollar Loans of such Lender shall instead be applied to repay the
ABR Loans made by such Lender in lieu of, or resulting from the conversion of,
such Eurodollar Loans.

       (b)    For purposes of this Section 2.13, a notice by any Lender shall
be effective as to each Eurodollar Loan, if lawful, on the last day of the
Interest Period currently applicable to such Eurodollar Loan; in all other
cases such notice shall be effective on the date of receipt.

       SECTION 2.14.  PRO RATA TREATMENT.  Except as provided below in this
Section 2.14 with respect to Competitive Borrowings and as required under
Sections 2.13 and 2.18, each Standby Borrowing, each payment or prepayment of
principal of any Standby Borrowing, each





                                      -32-
<PAGE>   37
payment of interest on the Standby Loans, each payment of the Facility Fees,
each reduction of the Commitments and each refinancing or conversion of any
Borrowing with a Standby Borrowing of any Type, shall be allocated pro rata
among the Lenders in accordance with their respective Commitments (or, if such
Commitments shall have expired or been terminated, in accordance with the
respective principal amounts of their outstanding Standby Loans).  Each payment
of principal of any Competitive Borrowing shall be allocated pro rata among the
Lenders participating in such Borrowing in accordance with the respective
principal amounts of their outstanding Competitive Loans comprising such
Borrowing.  Each payment of interest on any Competitive Borrowing shall be
allocated pro rata among the Lenders participating in such Borrowing in
accordance with the respective amounts of accrued and unpaid interest on their
outstanding Competitive Loans comprising such Borrowing.  For purposes of
determining the available Commitments of the Lenders at any time, each
outstanding Competitive Borrowing shall be deemed to have utilized the
Commitments of the Lenders (including those Lenders which shall not have made
Loans as part of such Competitive Borrowing) pro rata in accordance with such
respective Commitments.  Each Lender agrees that in computing such Lender's
portion of any Borrowing to be made hereunder, the Administrative Agent may, in
its discretion, round each Lender's percentage of such Borrowing to the next
higher or lower whole dollar amount.

       SECTION 2.15.  SHARING OF SETOFFS.  Each Lender agrees that if it shall,
through the exercise of a right of banker's lien, setoff or counterclaim, or
pursuant to a secured claim under Section 506 of Title 11 of the United States
Code or other security or interest arising from, or in lieu of, such secured
claim, received by such Lender under any applicable bankruptcy, insolvency or
other similar law or otherwise, or by any other means, obtain payment
(voluntary or involuntary) in respect of any Standby Loan or Loans as a result
of which the unpaid principal portion of its Standby Loans shall be
proportionately less than the unpaid principal portion of the Standby Loans of
any other Lender, it shall be deemed simultaneously to have purchased from such
other Lender at face value, and shall promptly pay to such other Lender the
purchase price for, a participation in the Standby Loans of such other Lender,
so that the aggregate unpaid principal amount of the Standby Loans and
participations in the Standby Loans held by each Lender shall be in the same
proportion to the aggregate unpaid principal amount of all Standby Loans then
outstanding as the principal amount of its Standby Loans prior to such exercise
of banker's lien, setoff or counterclaim or other event was to the principal
amount of all Standby Loans outstanding prior to such exercise of banker's
lien, setoff or counterclaim or other event; provided, however, that, if any
such purchase or purchases or adjustments shall be made pursuant to this
Section 2.15 and the payment giving rise thereto shall thereafter be recovered,
such purchase or purchases or adjustments shall be rescinded to the extent of
such recovery and the purchase price or prices or adjustment restored without
interest.  Each Borrower expressly consents to the foregoing arrangements and
agrees that any Lender holding a participation in a Standby Loan deemed to have
been so purchased may exercise any and all rights of banker's lien, setoff or
counterclaim with respect to any and all moneys owing by such Borrower to such
Lender by reason thereof as fully as if such Lender had made a Standby Loan in
the amount of such participation.

<PAGE>   38
       SECTION 2.16.  PAYMENTS.  (a)  Each Borrower shall make each payment
(including principal of or interest on any Borrowing or any Fees or other
amounts) hereunder from an account in the United States not later than 10:00
a.m., Houston time, on the date when due in dollars to the Administrative Agent
at its offices at 707 Travis Street, 8-CBBN-N 96, Houston, Texas 77002, in
immediately available funds.

       (b)    Whenever any payment (including principal of or interest on any
Borrowing or any Fees or other amounts) hereunder shall become due, or
otherwise would occur, on a day that is not a Business Day, such payment may be
made on the next succeeding Business Day, and such extension of time shall in
such case be included in the computation of interest or Fees, if applicable.

       SECTION 2.17.  TAXES.  (a)  Any and all payments of principal and
interest on any Borrowings, or of any Fees or indemnity or expense
reimbursements by a Borrower hereunder ("BORROWER PAYMENTS") shall be made, in
accordance with Section 2.16, free and clear of and without deduction for any
and all current or future United States Federal, state and local taxes, levies,
imposts, deductions, charges or withholdings, and all liabilities with respect
to such Borrower Payments, but only to the extent reasonably attributable to
such Borrower Payments, excluding (i) income taxes imposed on the net income of
the Administrative Agent, the CAF Agent or any Lender (or any transferee or
assignee thereof, including a participation holder (any such entity a
"TRANSFEREE")) and (i) franchise taxes imposed on the net income of the
Administrative Agent, the CAF Agent or any Lender (or Transferee), in each case
by the jurisdiction under the laws of which the Administrative Agent, the CAF
Agent or such Lender (or Transferee) is organized or doing business through
offices or branches located therein, or any political subdivision thereof (all
such nonexcluded taxes, levies, imposts, deductions, charges, withholdings and
liabilities, collectively or individually, "TAXES").  If any Borrower shall be
required to deduct any Taxes from or in respect of any sum payable hereunder to
any Lender (or any Transferee) or the Agents, (i) the sum payable shall be
increased by the amount (an "ADDITIONAL AMOUNT") necessary so that after making
all required deductions (including deductions applicable to additional sums
payable under this Section 2.17) such Lender (or Transferee) or Agent (as the
case may be) shall receive an amount equal to the sum it would have received
had no such deductions been made, (i) such Borrower shall make such deductions
and (i) such Borrower shall pay the full amount deducted to the relevant
Governmental Authority in accordance with applicable law.

       (b)    In addition, each Borrower shall pay to the relevant United
States Governmental Authority in accordance with applicable law any current or
future stamp or documentary taxes or any other excise or property taxes,
charges or similar levies that arise from any payment made hereunder or from
the execution, delivery or registration of, or otherwise with respect to, this
Agreement or the Letter Agreement ("OTHER TAXES").

       (c)    Each Borrower shall indemnify each Lender (or Transferee thereof)
and each Agent for the full amount of Taxes and Other Taxes with respect to
Borrower Payments paid





                                      -34-
<PAGE>   39
by such Lender (or Transferee) or such Agent, as the case may be, and any
liability (including penalties, interest and expenses (including reasonable
attorney's fees and expenses)) arising therefrom or with respect thereto,
whether or not such Taxes or Other Taxes were correctly or legally asserted by
the relevant United States Governmental Authority.  A certificate setting forth
and containing an explanation in reasonable detail of the manner in which such
amount shall have been determined and the amount of such payment or liability
prepared by a Lender, the CAF Agent, or the Administrative Agent on their
behalf, absent manifest error, shall be final, conclusive and binding for all
purposes.  Such indemnification shall be made within 30 days after the date the
Lender (or Transferee) or any Agent, as the case may be, makes written demand
therefor.

       (d)    If a Lender (or Transferee) or any Agent shall become aware that
it is entitled to claim a refund from a United States Governmental Authority in
respect of Taxes or Other Taxes as to which it has been indemnified by a
Borrower, or with respect to which a Borrower has paid additional amounts,
pursuant to this Section 2.17, it shall promptly notify such Borrower of the
availability of such refund claim and shall, within 30 days after receipt of a
request by such Borrower, make a claim to such United States Governmental
Authority for such refund at such Borrower's expense.  If a Lender (or
Transferee) or any Agent receives a refund (including pursuant to a claim for
refund made pursuant to the preceding sentence) in respect of any Taxes or
Other Taxes as to which it has been indemnified by a Borrower or with respect
to which a Borrower had paid additional amounts pursuant to this Section 2.17,
it shall within 30 days from the date of such receipt pay over such refund to
such Borrower (but only to the extent of indemnity payments made, or additional
amounts paid, by such Borrower under this Section 2.17 with respect to the
Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket
expenses of such Lender (or Transferee) or such Agent and without interest
(other than interest paid by the relevant United States Governmental Authority
with respect to such refund); provided, however, that such Borrower, upon the
request of such Lender (or Transferee) or such Agent, agrees to repay the
amount paid over to such Borrower (plus penalties, interest or other charges)
to such Lender (or Transferee) or such Agent in the event such Lender (or
Transferee) or such Agent is required to repay such refund to such United
States Governmental Authority.

       (e)    As soon as practicable, but in any event within 30 days, after
the date of any payment of Taxes or Other Taxes by a Borrower to the relevant
United States Governmental Authority, such Borrower will deliver to the
Administrative Agent, at its address referred to in Section 8.01, the original
or a certified copy of a receipt issued by such United States Governmental
Authority evidencing payment thereof.

       (f)    Without prejudice to the survival of any other agreement
contained herein, the agreements and obligations contained in this Section 2.17
shall survive the payment in full of the principal of and interest on all Loans
made hereunder.

<PAGE>   40
       (g)    Each Lender or Agent (or Transferee) that is organized under the
laws of a jurisdiction other than the United States, any State thereof or the
District of Columbia (a "NON-U.S. LENDER" or "NON U.S. AGENT", as applicable)
shall deliver to the Borrowers and the Administrative Agent two copies of
either United States Internal Revenue Service Form 1001 or Form 4224, properly
completed and duly executed by such Non-U.S. Lender claiming complete exemption
from, or reduced rate of, United States Federal withholding tax on payments by
any Borrower under this Agreement.  Such forms shall be delivered by each Non-
U.S. Lender on or before the date it becomes a party to this Agreement (or, in
the case of a Transferee that is a participation holder, on or before the date
such participation holder becomes a Transferee hereunder) and on or before the
date, if any, such Non-U.S. Lender changes its applicable lending office by
designating a different lending office (a "NEW LENDING OFFICE").  In addition,
each Non-U.S. Lender shall deliver such forms promptly upon the obsolescence or
invalidity of any form previously delivered by such Non-U.S. Lender.
Notwithstanding any other provision of this Section 2.17(g), a Non-U.S. Lender
shall not be required to deliver any form pursuant to this Section 2.17(g) that
such Non-U.S. Lender is not legally able to deliver.

       (h)    A Borrower shall not be required to indemnify any Non-U.S. Lender
or Non-U.S. Agent (including any Transferee), or to pay any additional amounts
to any Non-U.S. Lender or Non-U.S. Agent (including any Transferee), in respect
of United States Federal, state or local withholding tax pursuant to paragraph
(a) or (c) above to the extent that (i) the obligation to withhold amounts with
respect to United States Federal, state or local withholding tax existed on the
date such Non-U.S. Lender became a party to this Agreement (or, in the case of
a Transferee that is a participation holder, on the date such participation
holder became a Transferee hereunder) or, with respect to payments to a New
Lending Office, the date such Non-U.S. Lender designated such New Lending
Office with respect to a Loan; provided, however, that this clause (i) shall
not apply to any Transferee or New Lending Office that becomes a Transferee or
New Lending Office as a result of an assignment, participation, transfer or
designation made at the request of such Borrower; and provided further,
however, that this clause (i) shall not apply to the extent the indemnity
payment or additional amounts any Transferee, or Lender (or Transferee) through
a New Lending Office, would be entitled to receive (without regard to this
clause (i)) do not exceed the indemnity payment or additional amounts that the
person making the assignment, participation or transfer to such Transferee, or
Lender (or Transferee) making the designation of such New Lending Office, would
have been entitled to receive in the absence of such assignment, participation,
transfer or designation or (i) the obligation to pay such additional amounts or
such indemnity payments would not have arisen but for a failure by such
Non-U.S. Lender (including any Transferee) to comply with the provisions of
paragraph (g) above and (i) below.

       (i)    Any Lender (or Transferee) claiming any indemnity payment or
additional amounts payable pursuant to this Section 2.17 shall use reasonable
efforts (consistent with legal and regulatory restrictions) to file any
certificate or document reasonably requested in writing by a Borrower or to
change the jurisdiction of its applicable lending office if the making of such
a filing or change would avoid the need for or reduce the amount of any such
indemnity payment





                                      -36-
<PAGE>   41
or additional amounts that may thereafter accrue and would not, in the good
faith determination of such Lender (or Transferee), be otherwise
disadvantageous to such Lender (or Transferee).

       (j)    Nothing contained in this Section 2.17 shall require any Lender
(or Transferee) or any Agent to make available to such Borrower any of its tax
returns (or any other information) that it deems to be confidential or
proprietary.

       (k)    Notwithstanding anything herein to the contrary, the
indemnification obligations under this Section shall, to the extent
practicable, be allocated between the Borrowers based upon their relative
liability for the interest, fee or other payments in respect of which such
indemnification obligations arise.

       SECTION 2.18.  ASSIGNMENT OF COMMITMENTS UNDER CERTAIN CIRCUMSTANCES.
In the event that any Lender shall have delivered a notice or certificate
pursuant to Section 2.12 or 2.13, or any Borrower shall be required to make
additional payments to any Lender under Section 2.17, the Borrowers shall have
the right, at their own expense, upon notice to such Lender and the Agents, to
require such Lender to transfer and assign without recourse (in accordance with
and subject to the restrictions contained in Section 8.04) all such Lender's
interests, rights and obligations contained hereunder to another financial
institution approved by the Agents and the Borrowers (which approval shall not
be unreasonably withheld) which shall assume such obligations; provided that
(i) no such assignment shall conflict with any law, rule or regulation or order
of any Governmental Authority and (i) the assignee or the Borrowers, as the
case may be, shall pay to the affected Lender in immediately available funds on
the date of such assignment the principal of and interest accrued to the date
of payment on the Loans made by it hereunder and all other amounts accrued for
its account or owed to it hereunder.

       SECTION 2.19.  TERM ELECTION.  At least 20 but not more than 40 days
prior to the end of the Revolving Period, the Borrowers may, by delivering a
written notice to the Administrative Agent (with such notice being
irrevocable), and subject to the condition set forth below, elect that the
Maturity Date be extended for a period of 364 days, commencing on the last day
of the Revolving Period (any such election to so extend the Maturity Date being
the "TERM ELECTION").  Upon receipt of any such notice the Administrative Agent
shall promptly communicate such notice to the Lenders.  The Term Election shall
be effective on the last day of the Revolving Period, if and only if on such
date, no Default or Event of Default shall have occurred and be continuing.

                                  ARTICLE III
                         REPRESENTATIONS AND WARRANTIES

       Each Borrower represents and warrants to each of the Lenders as follows
(except in the case of the representations contained (i) in Section 3.05(a),
which are made by TUC only, and (ii) Section 3.05(b), which are made by TU
Electric only; and provided, that each representation or warranty made by any
Borrower in respect of TEG or any member of the TEG Group on any date up to
(but not including) the 120th day following the Unconditional Date shall be
subject to the qualification that such representation or warranty is true and
accurate insofar as such Borrower was aware as of the date of this Agreement):

       SECTION 3.1.  ORGANIZATION; POWERS.  Such Borrower (a) is a corporation
duly organized, validly existing and in good standing under the laws of the
jurisdiction of its organization, (b)  has all requisite power and authority to
own its property and assets and to carry on its business as now conducted and
as proposed to be conducted, (c) is qualified to do business in every
jurisdiction where such qualification is required, except where the failure so
to qualify would not result in a Material Adverse Change, and (d) has the
corporate power and authority to execute, deliver and perform its obligations

                                  ARTICLE VII
                                   THE AGENTS

       In order to expedite the transactions contemplated by this Agreement,
Chase Bank of Texas, National Association is hereby appointed to act as
Administrative Agent and Chase is hereby appointed to act as CAF Agent, on
behalf of the Lenders.  Each of the Lenders hereby irrevocably authorizes the
Agents to take such actions on behalf of such Lender or holder and to exercise
such powers as are specifically delegated to the Agents by the terms and
provisions hereof, together with such actions and powers as are reasonably
incidental thereto.  The Administrative Agent is hereby expressly authorized by
the Lenders and the CAF Agent, without hereby limiting any implied authority,
(a) to receive on behalf of the Lenders and the CAF





                                      -56-
<PAGE>   61
Agent all payments of principal of and interest on the Loans and all other
amounts due to the Lenders and the CAF Agent hereunder, and promptly to
distribute to each Lender and the CAF Agent its proper share of each payment so
received; (a) to give notice on behalf of each of the Lenders to the Borrowers
of any Event of Default of which the Administrative Agent has actual knowledge
acquired in connection with its agency hereunder; and (a) to distribute to each
Lender copies of all notices, financial statements and other materials
delivered by the Borrowers pursuant to this Agreement as received by the
Administrative Agent.

       No Agent or any of its directors, officers, employees or agents shall be
liable as such for any action taken or omitted by any of them except for its or
his or her own gross negligence or willful misconduct, or be responsible for
any statement, warranty or representation herein or the contents of any
document delivered in connection herewith, or be required to ascertain or to
make any inquiry concerning the performance or observance by the Borrowers of
any of the terms, conditions, covenants or agreements contained in this
Agreement.  The Agents shall not be responsible to the Lenders for the due
execution, genuineness, validity, enforceability or effectiveness of this
Agreement or other instruments or agreements.  The Agents may deem and treat
the Lender which makes any Loan as the holder of the indebtedness resulting
therefrom for all purposes hereof until it shall have received notice from such
Lender, given as provided herein, of the transfer thereof.  The Agents shall in
all cases be fully protected in acting, or refraining from acting, in
accordance with written instructions signed by the Required Lenders and, except
as otherwise specifically provided herein, such instructions and any action or
inaction pursuant thereto shall be binding on all the Lenders.  Each of the
Agents shall, in the absence of knowledge to the contrary, be entitled to rely
on any instrument or document believed by it in good faith to be genuine and
correct and to have been signed or sent by the proper person or persons.  No
Agent or any of its directors, officers, employees or agents shall have any
responsibility to the Borrowers on account of the failure of or delay in
performance or breach by the other Agent or any Lender of any of its
obligations hereunder or to the other Agent or any Lender on account of the
failure of or delay in performance or breach by any other Lender, the other
Agent or any Borrower of any of their respective obligations hereunder or in
connection herewith.  Each of the Agents may execute any and all duties
hereunder by or through agents or employees and shall be entitled to rely upon
the advice of legal counsel selected by it with respect to all matters arising
hereunder and shall not be liable for any action taken or suffered in good
faith by it in accordance with the advice of such counsel.

       The Lenders hereby acknowledge that the Agents shall be under no duty to
take any discretionary action permitted to be taken by it pursuant to the
provisions of this Agreement unless it shall be requested in writing to do so
by the Required Lenders.

       Subject to the appointment and acceptance of a successor Agent as
provided below, either Agent may resign at any time by notifying the Lenders
and the Borrowers.  Upon any such resignation, the Required Lenders shall have
the right to appoint a successor Agent acceptable to the Borrowers.  If no
successor shall have been so appointed by the Required Lenders and shall have
accepted such appointment within 30 days after the retiring Agent gives notice
of its





                                      -57-
<PAGE>   62
resignation, then the retiring Agent may, on behalf of the Lenders, appoint a
successor Agent, having a combined capital and surplus of at least $500,000,000
or an Affiliate of any such bank.  Upon the acceptance of any appointment as
Agent hereunder by a successor bank, such successor shall succeed to and become
vested with all the rights, powers, privileges and duties of the retiring Agent
and the retiring Agent shall be discharged from its duties and obligations
hereunder.  After any Agent's resignation hereunder, the provisions of this
Article and Section 8.05 shall continue in effect for its benefit in respect of
any actions taken or omitted to be taken by it while it was acting as Agent.

       With respect to the Loans made by it hereunder, each of the Agents, in
its individual capacity and not as an Agent shall have the same rights and
powers as any other Lender and may exercise the same as though it were not an
Agent, and each of the Agents and their Affiliates may accept deposits from,
lend money to and generally engage in any kind of business with the Borrowers
or any Subsidiary or other Affiliate thereof as if it were not an Agent.

       Each Lender agrees (i) to reimburse the Agents, on demand, in the amount
of its pro rata share (based on its Commitment hereunder or, if the Commitments
shall have been terminated, the amount of its outstanding Loans) of any
expenses incurred for the benefit of the Lenders in its role as Agent,
including counsel fees and compensation of agents and employees paid for
services rendered on behalf of the Lenders, which shall not have been
reimbursed by the Borrowers and (i) to indemnify and hold harmless each of the
Agents and any of its directors, officers, employees or agents, on demand, in
the amount of such pro rata share, from and against any and all liabilities,
taxes, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind or nature whatsoever which may be
imposed on, incurred by or asserted against it in any way relating to or
arising out of this Agreement or any action taken or omitted by it under this
Agreement to the extent the same shall not have been reimbursed by the
Borrowers; provided that no Lender shall be liable to any Agent for any portion
of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements resulting from the gross
negligence or willful misconduct of such Agent or any of its directors,
officers, employees or agents.  Each Lender agrees that any allocation made in
good faith by the Agents of expenses or other amounts referred to in this
paragraph between this Agreement and the Facility B Credit Agreement shall be
conclusive and binding for all purposes.

       Each Lender acknowledges that it has, independently and without reliance
upon the Agents or any other Lender and based on such documents and information
as it has deemed appropriate, made its own credit analysis and decision to
enter into this Agreement.  Each Lender also acknowledges that it will,
independently and without reliance upon the Agents or any other Lender and
based on such documents and information as it shall from time to time deem
appropriate, continue to make its own decisions in taking or not taking action
under or based upon this Agreement or any related agreement or any document
furnished hereunder or thereunder.

however, that (i) except in the case of an assignment to a Lender or an

       (c)    By executing and delivering an Assignment and Acceptance, the
assigning Lender thereunder and the assignee thereunder shall be deemed to
confirm to and agree with each other and the other parties hereto as follows:
(i) such assigning Lender warrants that it is the legal and beneficial owner of
the interest being assigned thereby free and clear of any adverse claim, (i)
except as set forth in (i) above, such assigning Lender makes no representation
or warranty and assumes no responsibility with respect to any statements,
warranties or representations made in or in connection with this Agreement, or
the execution, legality, validity, enforceability, genuineness, sufficiency or
value of this Agreement or any other instrument or document furnished pursuant
hereto or the financial condition of the Borrowers or the performance or
observance by the Borrowers of any obligations under this Agreement or any
other instrument or document furnished pursuant hereto; (i) such assignor and
such assignee represents and warrants that it is legally authorized to enter
into such Assignment and Acceptance; (i) such assignee confirms that it has
received a copy of this Agreement, together with copies of the most recent

documents and information as it has deemed appropriate to make its own credit
analysis and decision to enter into such Assignment and Acceptance; (i) such
assignee will independently and without reliance upon the Agents, such
assigning Lender or any other Lender and based on such documents and
information as it shall deem appropriate at the time, continue to make its own

assignee appoints and authorizes each Agent to take such action as agent on its
behalf and to exercise such powers under this Agreement as are delegated to
such Agent by the terms hereof, together with such powers as are reasonably

accordance with their terms all the obligations which by the terms of this
Agreement are required to be performed by it as a Lender.

       (d)    The Administrative Agent shall maintain at one of its offices in
the City of Houston a copy of each Assignment and Acceptance delivered to it
and a register for the recordation of the names and addresses of the Lenders,
and the Commitment of, and the principal amount of the Loans owing to, each
Lender pursuant to the terms hereof from time to time (the "REGISTER").  The
entries in the Register shall be conclusive in the absence of manifest error
and the Borrowers, the Agents and the Lenders may treat each person whose name
is recorded in the Register pursuant to the terms hereof as a Lender hereunder
for all purposes of this Agreement.  The Register shall be available for
inspection by each party hereto, at any reasonable time and from time to time
upon reasonable prior notice.

       (e)    Upon its receipt of a duly completed Assignment and Acceptance
executed by an assigning Lender and an assignee together with an Administrative
Questionnaire completed in respect of the assignee (unless the assignee shall
already be a Lender hereunder), the processing and recordation fee referred to

and the Agents to such assignment, the Administrative Agent shall (i) accept

       (f)    Each Lender may without the consent of the Borrowers or the
Agents sell participations to one or more banks or other entities in all or a
portion of its rights and obligations under this Agreement (including all or a
portion of its Commitment and the Loans owing to it); provided, however, that
(i) such Lender's obligations under this Agreement shall remain unchanged, (i)
such Lender shall remain solely responsible to the other parties hereto for the
performance of such obligations, (i) each participating bank or other entity
shall be entitled to the benefit of the cost protection provisions contained in
Sections 2.12, 2.17 and 8.05 to the same extent as if it were the selling
Lender (and limited to the amount that could have been claimed by the selling
Lender had it continued to hold the interest of such participating bank or
other entity), except that all claims made pursuant to such Sections shall be
made through such selling Lender, and (i) the Borrowers, the Agents and the
other Lenders shall continue to deal solely and directly with such selling
Lender in connection with such Lender's rights and obligations under this
Agreement, and such Lender shall retain the sole right to enforce the
obligations of the Borrowers under this Agreement and to approve any amendment,
modification or waiver of any provision of this Agreement (other than
amendments, modifications or waivers (x) decreasing any fees payable hereunder
or the amount of principal of, or the rate at which interest is payable on, the
Loans, (y) extending any scheduled principal payment date or date fixed for the
payment of interest on the Loans or (z) extending the Commitments).

       (g)    Any Lender or participant may, in connection with any assignment
or participation or proposed assignment or participation pursuant to this
Section, disclose to the assignee or participant or proposed assignee or
participant any information relating to the Borrowers furnished to such Lender
by or on behalf of the Borrowers; provided that, prior to any such disclosure,
each such assignee or participant or proposed assignee or participant shall
execute an agreement whereby such assignee or participant shall agree (subject
to customary exceptions) to preserve the confidentiality of any such
information.

       (h)    The Borrowers shall not assign or delegate any rights and duties
hereunder without the prior written consent of all Lenders, and any attempted
assignment or delegation (except as a consequence of a transaction expressly
permitted under Section 5.09) by a Borrower without such consent shall be void.


       (i)    Any Lender may at any time pledge all or any portion of its
rights under this Agreement to a Federal Reserve Bank; provided that no such
pledge shall release any Lender from its obligations hereunder or substitute
any such Bank for such Lender as a party hereto.  In order to facilitate such
an assignment to a Federal Reserve Bank, each Borrower shall, at the request of
the assigning Lender, duly execute and deliver to the assigning Lender a
promissory note or notes evidencing the Loans made to such Borrower by the
assigning Lender hereunder.

       SECTION 8.5.  EXPENSES; INDEMNITY.  (a)  The Borrowers agree to pay all
reasonable out-of-pocket expenses incurred by the Agents in connection with
entering into this Agreement or in connection with any amendments,
modifications or waivers of the provisions hereof (but only if such amendments,
modifications or waivers are requested by a Borrower) (whether or





                                      -62-
<PAGE>   67
not the transactions hereby contemplated are consummated), or incurred by the
Agents or any Lender in connection with the enforcement of their rights in
connection with this Agreement or in connection with the Loans made hereunder,
including the reasonable fees and disbursements of counsel for the Agents or,
in the case of enforcement following an Event of Default, the Lenders.

       (b)    The Borrowers agree to indemnify each Lender against any loss,
calculated in accordance with the next sentence, or reasonable expense which
such Lender may sustain or incur as a consequence of (a) any failure by such
Borrower to borrow or to refinance, convert or continue any Loan hereunder
(including as a result of such Borrower's failure to fulfill any of the
applicable conditions set forth in Article IV) after irrevocable notice of such
borrowing, refinancing, conversion or continuation has been given pursuant to
Section 2.03 or 2.04, (a) any payment, prepayment or conversion, or assignment
of a Eurodollar Loan or Fixed Rate Loan of such Borrower required by any other
provision of this Agreement or otherwise made or deemed made on a date other
than the last day of the Interest Period, if any, applicable thereto, (a) any
default in payment or prepayment of the principal amount of any Loan or any
part thereof or interest accrued thereon, as and when due and payable (at the
due date thereof, whether by scheduled maturity, acceleration, irrevocable
notice of prepayment or otherwise) or (d) the occurrence of any Event of
Default, including, in each such case, any loss or reasonable expense sustained
or incurred or to be sustained or incurred by such Lender in liquidating or
employing deposits from third parties, or with respect to commitments made or
obligations undertaken with third parties, to effect or maintain any Loan
hereunder or any part thereof as a Eurodollar Loan or a Fixed Rate Loan.  Such
loss shall include an amount equal to the excess, if any, as reasonably
determined by such Lender, of (i) its cost of obtaining the funds for the Loan
being paid, prepaid, refinanced, converted or not borrowed (assumed to be the
LIBO Rate or, in the case of a Fixed Rate Loan, the fixed rate of interest
applicable thereto) for the period from the date of such payment, prepayment,
refinancing or failure to borrow or refinance to the last day of the Interest
Period for such Loan (or, in the case of a failure to borrow or refinance the
Interest Period for such Loan which would have commenced on the date of such
failure) over (i) the amount of interest (as reasonably determined by such
Lender) that would be realized by such Lender in reemploying the funds so paid,
prepaid or not borrowed or refinanced for such period or Interest Period, as
the case may be.

       (c)    The Borrowers agree to indemnify the Agents, each Lender, each of
their Affiliates and the directors, officers, employees and agents of the
foregoing (each such person being called an "INDEMNITEE") against, and to hold
each Indemnitee harmless from, any and all losses, claims, damages, liabilities
and related expenses, including reasonable counsel fees and expenses, incurred
by or asserted against any Indemnitee arising out of (i)the consummation of the
transactions contemplated by this Agreement, including the Acquisition, (i) the
use of the proceeds of the Loans or (i) any claim, litigation, investigation or
proceeding relating to any of the foregoing, whether or not any Indemnitee is a
party thereto, including any of the foregoing arising from the negligence,
whether sole or concurrent, on the part of any Indemnitee; provided that such
indemnity shall not, as to any Indemnitee, be available to the extent that such
losses,





                                      -63-
<PAGE>   68
claims, damages, liabilities or related expenses (i) are determined by a final
judgment of a court of competent jurisdiction to have resulted from the gross
negligence or willful misconduct of such Indemnitee or (i) result from any
litigation brought by such Indemnitee against the Borrowers or by any Borrower
against such Indemnitee, in which a final, nonappealable judgment has been
rendered against such Indemnitee; provided, further, that each Borrower agrees
that it will not, nor will it permit any Subsidiary to, without the prior
written consent of each Indemnitee, settle, compromise or consent to the entry
of any judgment in any pending or threatened claim, action, suit or proceeding
in respect of which indemnification could be sought under the indemnification
provisions of this Section 8.05(c) (whether or not any Indemnitee is an actual
or potential party to such claim, action, suit or proceeding), unless such
settlement, compromise or consent does not include any statement as to an
admission of fault, culpability or failure to act by or on behalf of any
Indemnitee and does not involve any payment of money or other value by any
Indemnitee or any injunctive relief or factual findings or stipulations binding
on any Indemnitee.

       (d)    The provisions of this Section shall remain operative and in full
force and effect regardless of the expiration of the term of this Agreement,
the consummation of the transactions contemplated hereby, the repayment of any
of the Loans, the invalidity or unenforceability of any term or provision of
this Agreement or any investigation made by or on behalf of any Agent or any
Lender.  All amounts due under this Section shall be payable on written demand

occurred and be continuing, each Lender is hereby authorized at any time and
from time to time, to the fullest extent permitted by law, to set off and apply

at any time held and other indebtedness at any time owing by such Lender to or
for the credit or the account of the relevant Borrower against any of and all

       SECTION 8.8.  WAIVERS; AMENDMENT.  (a)  No failure or delay of either
Agent or any Lender in exercising any power or right hereunder shall operate as
a waiver thereof, nor shall any single or partial exercise of any such right or
power, or any abandonment or discontinuance of steps to enforce such a right or
power, preclude any other or further exercise thereof or the exercise of any
other right or power.  The rights and remedies of the Agents and the Lenders
hereunder are cumulative and are not exclusive of any rights or remedies which
they would otherwise have.  No waiver of any provision of this Agreement or
consent to any departure therefrom shall in any event be effective unless the
same shall be permitted by paragraph (b) below, and then such waiver or consent
shall be effective only in the specific instance and for the purpose for which
given.  No notice or demand on any Borrower or any Subsidiary in any case shall
entitle such party to any other or further notice or demand in similar or other
circumstances.

       (b)    Neither this Agreement nor any provision hereof may be waived,
amended or modified except pursuant to an agreement or agreements in writing
entered into by the Borrowers and the Required Lenders; provided, however, that
no such agreement shall (i) decrease the principal amount of, or extend the
maturity of or any scheduled principal payment date or date for the payment of
any interest on any Loan, or waive or excuse any such payment or any part
thereof, or decrease the rate of interest on any Loan, without the prior
written consent of each Lender affected thereby, (i) increase any Commitment or
decrease the Facility Fee of any Lender without the prior written consent of
such Lender, or (i) amend or modify the provisions of Section 2.14 or Section
8.04(h), the provisions of this Section or the definition of the "Required
Lenders", without the prior written consent of each Lender; provided further,
however, that no such agreement shall amend, modify or otherwise affect the
rights or duties of the Administrative Agent or the CAF Agent hereunder without
the prior written consent of the Administrative Agent or the CAF Agent, as the
case may be.  Each Lender shall be bound by any waiver, amendment or
modification authorized by this Section and any consent by any Lender pursuant
to this Section shall bind any assignee of its rights and interests hereunder.

       SECTION 8.9.  ENTIRE AGREEMENT.  THIS AGREEMENT (INCLUDING THE SCHEDULES
AND EXHIBITS HERETO) AND THE LETTER AGREEMENT CONSTITUTE A "LOAN AGREEMENT" AS
DEFINED IN SECTION 26.02(A) OF THE TEXAS BUSINESS AND COMMERCE CODE, AND
REPRESENT THE ENTIRE CONTRACT AMONG THE PARTIES RELATIVE TO THE SUBJECT MATTER
HEREOF AND THEREOF.  ANY PREVIOUS AGREEMENT, WHETHER WRITTEN OR ORAL, AMONG THE
PARTIES WITH RESPECT TO THE SUBJECT MATTER HEREOF, INCLUDING, WITHOUT
LIMITATION, THE EXISTING TU CREDIT AGREEMENTS, IS SUPERSEDED BY THIS AGREEMENT
AND THE LETTER AGREEMENT.  THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE
PARTIES.  NOTHING IN THIS AGREEMENT, EXPRESSED OR IMPLIED, IS INTENDED TO
CONFER UPON ANY PARTY OTHER THAN THE PARTIES HERETO ANY RIGHTS, REMEDIES,
OBLIGATIONS OR LIABILITIES UNDER OR BY REASON OF THIS AGREEMENT.

       SECTION 8.10.  SEVERABILITY.  In the event any one or more of the
provisions contained in this Agreement should be held invalid, illegal or
unenforceable in any respect, the validity, legality and enforceability of the
remaining provisions contained herein shall not in any way be affected or
impaired thereby.  The parties shall endeavor in good-faith negotiations to
replace the invalid, illegal or unenforceable provisions with valid provisions
the economic effect of which comes as close as possible to that of the invalid,
illegal or unenforceable provisions.

       SECTION 8.11.  COUNTERPARTS.  This Agreement may be executed in two or
more counterparts, each of which shall constitute an original but all of which
when taken together shall constitute but one contract, and shall become
effective as provided in Section 8.03.

       SECTION 8.12.  HEADINGS.  Article and Section headings and the Table of
Contents used herein are for convenience of reference only, are not part of
this Agreement and are not to affect the construction of, or to be taken into
consideration in interpreting, this Agreement.

       SECTION 8.13.  INTEREST RATE LIMITATION.  (a)  Notwithstanding anything
herein to the contrary, if at any time the applicable interest rate, together
with all fees and charges which are treated as interest under applicable law
(collectively the "CHARGES"), as provided for herein or in any other document
executed in connection herewith, or otherwise contracted for, charged,
received, taken or reserved by any Lender, shall exceed the maximum lawful rate
(the "MAXIMUM RATE") which may be contracted for, charged, taken, received or
reserved by such Lender in accordance with applicable law, the rate of interest
payable on the Loans of such Lender, together with all Charges payable to such
Lender, shall be limited to the Maximum Rate.

       (b)    If the amount of interest, together with all Charges, payable for
the account of any Lender in respect of any interest computation period is
reduced pursuant to paragraph (a) of this Section and the amount of interest,
together with all Charges, payable for such Lender's account in respect of any
subsequent interest computation period, computed pursuant to Section 2.07,
would be less than the Maximum Rate, then the amount of interest, together with
all Charges, payable for such Lender's account in respect of such subsequent
interest computation period shall, to the extent permitted by applicable law,
be automatically increased to such Maximum Rate; provided that at no time shall
the aggregate amount by which interest paid for the account of any Lender has
been increased pursuant to this paragraph (b) exceed the aggregate amount by
which interest, together with all Charges, paid for its account has theretofore
been reduced pursuant to paragraph (a) of this Section.

       SECTION 8.14.  JURISDICTION; VENUE.  (a)  Each Borrower hereby
irrevocably and unconditionally submits, for itself and its property, to the
nonexclusive jurisdiction of any New York State court or Federal court of the
United States of America sitting in New York City, and any appellate court from
any thereof, in any action or proceeding arising out of or relating to this
Agreement, or for recognition or enforcement of any judgment, and each of the
parties hereto hereby irrevocably and unconditionally agrees that all claims in
respect of any





                                      -66-
<PAGE>   71
such action or proceeding may be heard and determined in such New York State
or, to the extent permitted by law, in such Federal court.  Each of the parties
hereto agrees that a final judgment in any such action or proceeding shall be
conclusive and may be enforced in other jurisdictions by suit on the judgment
or in any other manner provided by law.  Subject to the foregoing and to
paragraph (b) below, nothing in this Agreement shall affect any right that any
party hereto may otherwise have to bring any action or proceeding relating to
this Agreement against any other party hereto in the courts of any
jurisdiction.

       (b)    Each Borrower hereby irrevocably and unconditionally waives, to
the fullest extent it may legally and effectively do so, any objection which it
may now or thereafter have to the laying of venue of any suit, action or
proceeding arising out of or relating to this Agreement in any New York State
or Federal court.  Each of the parties hereto hereby irrevocably waives, to the
fullest extent permitted by law, the defense of an inconvenient forum to the
maintenance of such action or proceeding in any such court.

       SECTION 8.15.  CONFIDENTIALITY.  Each Lender shall use its best efforts
to hold in confidence all information, memoranda, or extracts furnished to such
Lender (directly or through the Agents) by the Borrowers hereunder or in
connection with the negotiation hereof; provided that such Lender may disclose
any such information, memoranda or extracts (i) to its accountants or counsel,
(i) to any regulatory agency having authority to examine such Lender, (i) as
required by any legal or governmental process or otherwise by law, (i) except
as provided in the last sentence of Section 5.03, to any person to which such
Lender sells or proposes to sell an assignment or a participation in its Loans
hereunder, if such other person agrees for the benefit of the Borrowers to
comply with the provisions of this Section and (i) to the extent that such
information, memoranda or extracts shall be publicly available or shall have
become known to such Lender independently of any disclosure by any Borrower
hereunder or in connection with the negotiation hereof.  Notwithstanding the
foregoing, any Lender may disclose the provisions of this Agreement and the
amounts, maturities and interest rates of its Loans to any purchaser or
potential purchaser of such Lender's interest in any Loan.

To the Lenders listed on
Schedule 2.01 of each
Credit Agreements referred to below
and from time to time party to such Credit Agreements

Ladies and Gentlemen:

       We advise you that we have acted as counsel to Texas Utilities Company,
a Texas Corporation ("TUC"), Texas Utilities Electric Company, a Texas
corporation ("TU ELECTRIC") and Enserch Corporation ("ENSERCH") in connection
with the 364-Day Competitive Advance and Revolving Credit Facility Agreement
and the 5-Year Competitive Advance and Revolving Credit Facility Agreement
(collectively, the "CREDIT AGREEMENTS"), each dated as of March 2, 1998, among,
TUC, TU Electric, Enserch Corporation, Chase Bank of Texas, National
Association, as Administrative Agent, The Chase Manhattan Bank, as Competitive
Advance Facility Agent, and the banks listed on Schedule 2.01 thereof (the
"LENDERS"), and have participated in the preparation of or have examined and
are familiar with (a) the current financial statements and reports filed by
TUC, TU Electric and Enserch with the Securities and Exchange Commission
pursuant to the Securities Exchange Act of 1934, as amended, (b) the Credit
Agreements, (C) the articles of incorporation and by-laws of TUC, TU Electric
and Enserch and (d) such other records and documents as we have deemed
necessary for the purposes of this opinion.

       As to those matters stated herein to be "to our knowledge" or "known to
us" such examination has been limited to discussions with and certificates from
officers of TUC and TU Electric and Enserch and we have not conducted any
independent investigation or verification or taken any action beyond such
discussions and certificates, nor made any search of the records of any
Governmental Authority with respect to such matters.

       Capitalized terms used in this opinion and not defined herein shall have
the respective meanings assigned thereto in the Credit Agreements.  This
opinion is delivered to you pursuant to Section 4.01(c) of the Credit
Agreements.

       We are members of the New York Bar and do not hold ourselves out as
experts on the laws of the State of Texas. As to all matters of Texas law
(including incorporation of TUC,





                          FACILITY A CREDIT AGREEMENT
<PAGE>   98
                                                                           D-1-2

TU Electric and Enserch, titles to properties, franchises, licenses and
permits) we have, with your consent, relied upon an opinion of even date
herewith delivered to you by Worsham, Forsythe & Wooldridge, L.L.P., general
counsel for TUC, TU Electric and Enserch.  While we represent TUC and TU
Electric on a regular basis, our engagement has been limited to specific
matters as to which we were consulted.  We have no direct knowledge of the day-
to-day affairs of TUC, TU Electric or Enserch and have not reviewed generally
their business affairs.  Accordingly, we are relying upon representations of
TUC, TU Electric and Enserch contained in the Credit Agreements, in
certificates furnished pursuant thereto, and in certificates furnished to us by
officers of TUC, TU Electric and Enserch.

       For purposes of the opinions expressed below, we have assumed (i) the
authenticity of all documents submitted to us as originals, (ii) the conformity
to the originals of all documents submitted to us as certified or photostatic
copies and the authenticity of the originals of such copies, (iii) the
genuineness of all signatures other than on behalf of TUC, TU Electric and
Enserch, (iv) the legal capacity of natural persons, (v) the power, corporate
or otherwise, of all parties other than TUC, TU Electric and Enserch to enter
into and to perform all of their obligations under such documents, and (vi) the
due authorization, execution and delivery of all documents by all parties other
than TUC, TU Electric and Enserch.

       Based on the foregoing, we are of the opinion that:

       1.  Each of TUC, TU Electric and Enserch (i) is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Texas, (ii) has all requisite power and authority to own its property and
assets and to carry on its business as now conducted, (iii) is qualified to do
business in every jurisdiction within the United States where such
qualification is required, except where the failure so to qualify would not
result in a Material Adverse Change, and (iv) has all requisite corporate power
and authority to execute, deliver and perform its obligations under the Credit
Agreements and to borrow funds thereunder.

       2.  The execution, delivery and performance by each of TUC, TU Electric
and Enserch of the Credit Agreements and the Borrowings by each of them
thereunder (collectively, the "TRANSACTIONS") and the consummation of the
Acquisition (i) have been duly authorized by all requisite corporate action and
(ii) will not (a) violate (1) any law, statute, rule or regulation presently
binding on or applicable to TUC, TU Electric or Enserch, or the articles of
incorporation, as amended, or by-laws of TUC, TU Electric or Enserch, (2) to
our knowledge, any order of any Governmental Authority presently applicable to
TUC, TU Electric or Enserch or (3) any provision of any indenture, agreement or
other instrument known to us to which TUC, TU Electric or Enserch or its
property is bound, (b) be in conflict with, result in a breach of or constitute
(alone or with notice or lapse of time or both) a default under any such
indenture, agreement or other instrument or (c) except as contemplated by the
UK Facility

Agreement, result in the creation or imposition of any lien upon or with
respect to any property or assets of TUC, TU Electric or Enserch.

       3.  The Credit Agreements have been duly executed and delivered by TUC,
TU Electric and Enserch and constitute legal, valid and binding obligations of
TUC, TU Electric and Enserch enforceable against each of them in accordance
with their terms except as enforceability may be limited by bankruptcy,
insolvency, reorganization, moratorium or other similar laws affecting the
enforcement of creditors' rights generally and by general equitable principles
(regardless of whether such enforceability is considered in a proceeding in
equity or at law).

       4.  No action, consent or approval of, registration or filing with, or
any other action by, any Governmental Authority (including pursuant to the
Public Utility Holding Company Act of 1935, as amended) is required on the part
of TUC, TU Electric or Enserch in connection with the Transactions or the
Acquisition, except such as have been made or obtained and are in full force
and effect and, in the case of the Acquisition, (i) expiration or termination
of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of
1979 and (i) the filing by TUC of a registration statement on Form S-4 under
the Securities Act of 1933, as amended, relating to shares of common stock of
TUC to be issued in connection with the Acquisition, and action by the
Securities and Exchange Commission declaring said registration statement to be
effective under such Act.

       5.  (a)  None of TUC, TU Electric nor Enserch nor any of their
respective Subsidiaries is an "investment company" as defined in, or subject to
regulation under, the Investment Company Act of 1940, as amended, and (b) TUC,
TU Electric and Enserch and each of their respective Subsidiaries is exempt
from all provisions of the Public Utility Holding Company Act of 1935, as
amended, and the rules and regulations thereunder, except for Sections 9(a)(2)
and 33 of such Act and the rules and regulations thereunder, and the execution,
delivery and performance by each of TUC, TU Electric and Enserch of the Credit
Agreements and the consummation of the Acquisition do not violate any
provisions of such Act or any rule or regulation thereunder.

       6.  Except as described in the Annual Reports on Form 10-K for the year
ended December 31, 1996 and the Quarterly Reports on Form 10-Q for the quarters
ended March 31, 1997, June 30, 1997 and September 30, 1997, filed by TUC, TU
Electric and Enserch with the Securities and Exchange Commission and as set
forth in Schedule 3.06 to the Credit Agreements, to our knowledge there is no
action, suit, or proceeding at law or in equity or by or before any
Governmental Authority now pending or threatened against or affecting TUC, TU
Electric or Enserch (i) which involves the Transactions or (ii) as to which
there is a reasonable possibility of an adverse determination and which, if
adversely determined, could, individually or in the aggregate, result in a
Material Adverse Change.

                                                                  _____ __, 1998


To the Lenders listed on
Schedule 2.01 of each of the
Credit Agreements referred to below

Ladies and Gentlemen:

       We have acted as general counsel for Texas Utilities Company, a Texas
corporation ("TUC"), Texas Utilities Electric Company, a Texas corporation ("TU
ELECTRIC") and Enserch Corporation ("ENSERCH"), in connection with the
execution and delivery of the 364-Day Competitive Advance and Revolving Credit
Facility Agreement and the 5-Year Competitive Advance and Revolving Credit
Facility Agreement (collectively, the "CREDIT AGREEMENTS"), each dated as of
March 2, 1998, among TUC, TU Electric, Enserch Corporation, the banks listed on
Schedule 2.01 thereof (the "LENDERS"), Chase Bank of Texas, National
Association, as Administrative Agent and The Chase Manhattan Bank, as
Competitive Advance Facility Agent.

       Capitalized terms used in this opinion and not defined herein shall have
the respective meanings assigned thereto in the Credit Agreements.  This
opinion is delivered to you pursuant to Section 4.01(c) of the Credit
Agreements.

       In connection with this opinion we have examined a counterpart of the
Credit Agreements executed by TUC, TU Electric and Enserch and have also made
such examination of other documents and of certificates of public officials and
corporate officers of TUC, TU Electric and Enserch, and have made such other
legal and factual examinations and inquiries as we have deemed necessary or
advisable for the purpose of rendering this opinion; but as to those matters
stated herein to be "to our knowledge" or "known to us" such examination has
been limited to discussions with and certificates from officers of TUC, TU
Electric and Enserch and we have not conducted any independent investigation or
verification or taken any action beyond such discussions and certificates, nor
made any search of the records of any Governmental Authority with respect to
such matters.

       For purposes of the opinions expressed below, we have assumed (i) the
authenticity of all documents submitted to us as originals, (ii) the conformity
to the originals of all documents submitted to us as certified or photostatic
copies and the authenticity of the originals of such copies, (iii) the
genuineness of all signatures other than on behalf of TUC, TU Electric and

                                                                           D-2-2

Enserch, (iv) the legal capacity of natural persons, (v) the power, corporate
or otherwise, of all parties other than TUC, TU Electric and Enserch to enter
into and to perform all of their obligations under such documents, and (vi) the
due authorization, execution and delivery of all documents by all parties other
than TUC, TU Electric and Enserch.

       Based upon, and subject to, the foregoing and to such further
limitations and qualifications stated below, we are of the opinion that:

       1.  Each of TUC, TU Electric and Enserch (i) is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Texas, (ii) has all requisite power and authority to own its property and
assets and to carry on its business as now conducted, (iii) is qualified to do
business in every jurisdiction within the United States where such
qualification is required, except where the failure so to qualify would not
result in a Material Adverse Change, and (iv) has all requisite corporate power
and authority to execute, deliver and perform its obligations under the Credit
Agreements and to borrow funds thereunder.

       2.  The execution, delivery and performance by each of TUC, TU Electric
and Enserch of the Credit Agreements and the Borrowings by each of them
(collectively, the "TRANSACTIONS") and the consummation of the Acquisition (i)
have been duly authorized by all requisite corporate action and (ii) will not
(a) violate (1) any law, statute, rule or regulation presently binding on or
applicable to TUC, TU Electric or Enserch, or the articles of incorporation, as
amended, or by-laws of TUC, TU Electric or Enserch, (2) to our knowledge, any
order of any Governmental Authority presently applicable to TUC, TU Electric or
Enserch or (3) any provision of any indenture, agreement or other instrument
known to us to which TUC, TU Electric or Enserch is a party or by which TUC, TU
Electric or Enserch or its property is bound, (b) be in conflict with, result
in a breach of or constitute (alone or with notice or lapse of time or both) a
default under any such indenture, agreement or other instrument or (c) result
in the creation or imposition of any lien upon or with respect to any property
or assets now owned or hereafter acquired by TUC, TU Electric or Enserch.

       3.  The Credit Agreements have been duly executed and delivered by TUC,
TU Electric and Enserch and constitute legal, valid and binding obligations of
TUC, TU Electric and Enserch enforceable against each of them in accordance
with their terms except as enforceability may be limited by bankruptcy,
insolvency, reorganization, moratorium or other laws affecting the enforcement
of creditors' rights generally and by general equitable principles (regardless
of whether such enforceability is considered in a proceeding in equity or at
law).

       4.  No action, consent or approval of, registration or filing with, or
any other action by, any Government Authority (including pursuant to the Public
Utility Holding Company Act of 1935, as amended) is required on the part of
TUC, TU Electric or Enserch in connection with the Transactions or the
Acquisition, except as such as have been made or obtained and are in

                                                                           D-2-3

full force and effect and, in the case of the Acquisition, (i) expiration or
termination of the waiting period under the Hart-Scott-Rodino Antitrust
Improvements Act of 1979 and (i) the filing by the Company of a Registration
Statement on Form S-4 under the Securities Act of 1933, as amended, and action
by the Securities and Exchange Commission declaring said Registration Statement
effective.

       5.  None of TUC, TU Electric nor Enserch nor any of their respective
Subsidiaries is an "investment company" as defined in, or subject to regulation
under, the Investment Company Act of 1940, as amended.  TUC, TU Electric and
each of their respective Subsidiaries is exempt from all provisions of the
Public Utility Holding Company Act of 1935, as amended, and rules and
regulations thereunder, except for Sections 9(a)(2) and 33 of such Act and
rules and regulations thereunder, and the execution, delivery and performance
by TUC, TU Electric and Enserch of the Credit Agreements and the consummation
of the Acquisition do not violate any provision of such Act or any rule or
regulation thereunder.

       6.  Except as described in the Annual Reports on Form 10-K for the year
ended December 31, 1996 and the Quarterly Reports on Form 10-Q for the quarters
ended March 31, 1997, June 30, 1997 and September 30, 1997, filed by TUC, TU
Electric and Enserch with the Securities and Exchange Commission and as set
forth in Schedule 3.06 to the Credit Agreements, to our knowledge there is no
action, suit or proceeding at law or in equity or by or before any Governmental
Authority now pending or threatened against or affecting TUC, TU Electric or
Enserch (i) which involves the Transactions or the Acquisition or (ii) as to
which there is a reasonable possibility of an adverse determination and which,
if adversely determined, would, individually or in the aggregate, result in a
Material Adverse change.

       7.  To our knowledge, TUC, TU Electric and Enserch are not in violation
of any law, rule or regulation, or in default with respect to any judgment,
writ, injunction or decree of any Governmental Authority, where such violation
or default would result in a Material Adverse Change.

       8.  To our knowledge, after due inquiry, the proposed use of the
proceeds of the Loans is in accordance with the Credit Agreements, and, if so
used, will not violate the Margin Regulations.

       9.  We believe that a Texas court would give effect to the provisions of
the Credit Agreements that state that they are to be construed in accordance
with New York law; provided, however, that we render no opinion as to the
application of New York law that is contrary to a fundamental or public policy
of the State of Texas.

       We are members of the State Bar of Texas and do not purport to be
experts on, nor do we opine as to, the laws of any jurisdiction other than the
State of Texas and the federal laws

              ("TU ELECTRIC"), and ENSERCH CORPORATION, a Texas corporation and
              a wholly owned subsidiary of TUC ("ENSERCH" and, together with
              TUC and TU Electric, the "BORROWERS", and each individually, a
              "BORROWER"); the lenders listed in Schedule 2.01 (together with

              BANK ("CHASE"), as Competitive Advance Facility Agent (in such
              capacity, the "CAF AGENT"); and CHASE BANK OF TEXAS, NATIONAL
              ASSOCIATION ("CHASE BANK OF TEXAS"), as administrative agent for
              the Lenders (in such capacity, the "ADMINISTRATIVE AGENT"; and,
              together with the CAF Agent, the "AGENTS").

       The Borrowers have requested the Lenders to extend credit in the form of
Standby Borrowings (such term and each other capitalized term used herein
having the meaning given it in Article I) to the Borrowers in an aggregate
principal amount at any time outstanding not in excess of $1,400,000,000.  The
Borrowers have also requested the Lenders to provide a procedure pursuant to
which the Borrowers may invite the Lenders to bid on an uncommitted basis on
short-term borrowings by the Borrowers.  Subject to the terms and conditions
set forth herein, the proceeds of any such borrowings are to be used to
refinance the Existing TUC Credit Agreements and for working capital and other
corporate purposes, including commercial paper back-up.  The Lenders are
willing to extend such credit to the Borrowers on the terms and subject to the
conditions herein set forth.

       Accordingly, the parties hereto agree as follows:

       any day, the annual rate (rounded upwards to the next 1/100 of 1%) most

       the quotations for the day of such transactions received by Chase from
       three Federal funds brokers of recognized standing selected by it.  If
       for any reason Chase shall have determined (which determination shall be
       conclusive absent manifest error; provided that Chase, shall, upon
       request, provide to the applicable Borrower a certificate setting forth
       in reasonable detail the basis for such determination) that it is unable
       to ascertain the Federal Funds Effective Rate for any reason, including
       the inability of Chase to obtain sufficient quotations in accordance
       with the terms thereof, the Alternate Base Rate shall be determined
       without regard to clause (a) of the first sentence of this definition
       until the circumstances giving rise to such inability no longer exist.

       date of such change in the Prime Rate or the Federal Funds Effective
       Rate, respectively.

       any Borrower, the percentage per annum set forth in the column
       identified as Level 1, Level 2, Level 3 or  Level 4 below, based upon
       the Level corresponding to the lower Debt Rating of such Borrower at the
       time of determination, provided that, if and for so long as any Offer
       Loans (as defined in the Facility A Credit Agreement) shall remain
       outstanding on or after the 364th day following the date hereof, the
       Applicable Margins set forth below  with respect to each Level shall be
       increased by .50% with respect to Eurodollar Loans outstanding and the
       Applicable Margins with respect to ABR Loans shall be equal to, for each
       Level, the then-effective Applicable Margin for Eurodollar Loans less
       1.00% (but not negative).  Any change in the Applicable Margin shall be
       effective on the date on which the applicable rating agency announces
       any change in the Debt Rating.

       SECTION 2.1.  COMMITMENTS.  Subject to the terms and conditions and
relying upon the representations and warranties herein set forth, each Lender
agrees, severally and not jointly, to make Standby Loans, at any time and from
time to time until the earlier of the Maturity Date and the termination of the
Commitment of such Lender, to each Borrower in an aggregate principal amount at
any time outstanding not to exceed such Lender's Commitment minus the amount by
which the Competitive Loans made to any Borrower and outstanding at such time
shall be deemed to have used such Commitment pursuant to Section 2.14, subject,
however, to the conditions that (i) at no time shall the sum of (x) the
outstanding aggregate principal amount of all Standby Loans plus (y) the
outstanding aggregate principal amount of all Competitive Loans exceed the
Total Commitment, (i) at no time shall the sum of the outstanding aggregate
principal amount of Loans hereunder plus Loans under and as defined in Facility
A used, in each case, for purposes described in Section 5.08(ii) of the
Facility A Credit Agreement exceed $2,930,000,000, (i) at no time shall the sum
of (x) the outstanding aggregate principal amount of all Loans made to Enserch
plus (y) the outstanding aggregate principal amount of all Loans under and as
defined in the Facility A Credit Agreement made to Enserch exceed $650,000,000,
(i) unless and until the TU Electric Approval Date shall have occurred, at no
time shall the sum of (x) the outstanding aggregate principal amount of all
Loans made to TU Electric plus (y) the outstanding aggregate principal amount
of all Loans under and as defined in the Facility A Credit Agreement made to TU
Electric exceed $1,250,000,000, (i) at no time shall the outstanding aggregate
principal amount of all Standby Loans made by any Lender exceed the amount of
such Lender's Commitment and (i) at all times, the outstanding aggregate
principal amount of all Standby Loans made by each Lender to each Borrower
shall equal the product of (B) the percentage which such Lender's Commitment
represents of the Total Commitment times (B) the outstanding aggregate
principal amount of all Standby Loans made to such Borrower.

       Within the foregoing limits, the Borrowers may borrow, pay or prepay and
reborrow Standby Loans hereunder, on and after the Effective Date and prior to
the Maturity Date, subject to the terms, conditions and limitations set forth
herein.

       SECTION 2.2.  LOANS.  (a)  Each Standby Loan shall be made as part of a
Borrowing consisting of Loans made by the Lenders ratably in accordance with
their respective Commitments; provided, however, that the failure of any Lender
to make any Standby Loan shall not in itself relieve any other Lender of its
obligation to lend hereunder (it being understood, however, that no Lender
shall be responsible for the failure of any other Lender to make any Loan
required to be made by such other Lender).  Each Competitive Loan shall be made
in accordance with the





                                      -18-
<PAGE>   23
procedures set forth in Section 2.03.  The Standby Loans or Competitive Loans
comprising any Borrowing shall be (i) in the case of Competitive Loans, in an
aggregate principal amount which is an integral multiple of $1,000,000 and not
less than $5,000,000 and (i) in the case of Standby Loans, in an aggregate
principal amount which is an integral multiple of $5,000,000 and not less than
$25,000,000 (or an aggregate principal amount equal to the remaining balance of
the available Commitments).

       (b)    Each Competitive Borrowing shall be comprised entirely of
Eurodollar Competitive Loans or Fixed Rate Loans, and each Standby Borrowing
shall be comprised entirely of Eurodollar Standby Loans or ABR Loans, as the
Borrower may request pursuant to Section 2.03 or 2.04, as applicable. Each
Lender may at its option make any Eurodollar Loan by causing any domestic or
foreign branch or Affiliate of such Lender to make such Loan; provided that any
exercise of such option shall not affect the obligation of the Borrower to
repay such Loan in accordance with the terms of this Agreement.  Borrowings of
more than one Type may be outstanding at the same time.

       (c)    Subject to paragraph (d) below, each Lender shall make each Loan
to be made by it hereunder on the proposed date thereof by wire transfer of
immediately available funds to the Administrative Agent in Houston, Texas, not
later than noon, Houston time, and the Administrative Agent shall by 2:00 p.m.,
Houston time, credit the amounts so received to the account or accounts
specified from time to time in one or more notices delivered by the applicable
Borrower to the Administrative Agent or, if a Borrowing shall not occur on such
date because any condition precedent herein specified shall not have been met,
return the amounts so received to the respective Lenders.  Competitive Loans
shall be made by the Lender or Lenders whose Competitive Bids therefor are
accepted pursuant to Section 2.03 in the amounts so accepted.  Standby Loans
shall be made by the Lenders pro rata in accordance with Section 2.14.  Unless
the Administrative Agent shall have received notice from a Lender prior to the
date of any Borrowing that such Lender will not make available to the
Administrative Agent such Lender's portion of such Borrowing, the
Administrative Agent may assume that such Lender has made such portion
available to the Administrative Agent on the date of such Borrowing in
accordance with this paragraph (c) and the Administrative Agent may, in
reliance upon such assumption, make available to the Borrower on such date a
corresponding amount.  If and to the extent that such Lender shall not have
made such portion available to the Administrative Agent, such Lender and such
Borrower (without waiving any claim against such Lender for such Lender's
failure to make such portion available) severally agree to repay to the
Administrative Agent forthwith on demand such corresponding amount together
with interest thereon, for each day from the date such amount is made available
to the Borrower until the date such amount is repaid to the Administrative
Agent at (i) in the case of the Borrower, the interest rate applicable at the
time to the Loans comprising such Borrowing and (i) in the case of such Lender,
the Federal Funds Effective Rate.  If such Lender shall repay to the
Administrative Agent such corresponding amount, such amount shall constitute
such Lender's Loan as part of such Borrowing for purposes of this Agreement.

       (d)    A Borrower may refinance all or any part of any Standby Borrowing
with a Standby Borrowing of the same or a different Type, subject to the
conditions and limitations set forth in this Agreement.  Any Standby Borrowing
or part thereof so refinanced shall be deemed to be repaid or prepaid in
accordance with Section 2.06 or 2.11, as applicable, with the proceeds of a new
Standby Borrowing, and the proceeds of the new Standby Borrowing, to the extent
they do not exceed the principal amount of the Standby Borrowing being
refinanced, shall not be paid by the Lenders to the Administrative Agent or by
the Administrative Agent to such Borrower pursuant to paragraph (c) above.

       SECTION 2.3.  COMPETITIVE BID PROCEDURE.  (a)  In order to request
Competitive Bids, a Borrower shall hand deliver or telecopy to the CAF Agent a
duly completed Competitive Bid Request in the form of Exhibit A-1 hereto, to be
received by the CAF Agent (i) in the case of a Eurodollar Competitive
Borrowing, not later than 11:00 a.m., New York City time, four Business Days
before a proposed Competitive Borrowing and (i) in the case of a Fixed Rate
Borrowing, not later than 11:00 a.m., New York City time, one Business Day
before a proposed Competitive Borrowing.  No ABR Loan shall be requested in, or
made pursuant to, a Competitive Bid Request.  A Competitive Bid Request that
does not conform substantially to the format of Exhibit A-1 may be rejected in
the CAF Agent's sole discretion, and the CAF Agent shall promptly notify the
Borrower of such rejection by telecopy.  Each Competitive Bid Request shall
refer to this Agreement and specify (w) whether the Borrowing then being
requested is to be a Eurodollar Borrowing or a Fixed Rate Borrowing, (x) the
date of such Borrowing (which shall be a Business Day) and the aggregate
principal amount thereof which shall be in a minimum principal amount of
$5,000,000 and in an integral multiple of $1,000,000, and (y) the Interest
Period with respect thereto (which may not end after the Maturity Date).
Promptly after its receipt of a Competitive Bid Request that is not rejected as
aforesaid, the CAF Agent shall telecopy to each Lender a Notice of Competitive
Bid Request in the form of Exhibit A-2 inviting the Lenders to bid, on the
terms and conditions of this Agreement, to make Competitive Loans.

       (b)    Each Lender invited to bid may, in its sole discretion, make one
or more Competitive Bids to the Borrower responsive to such Borrower's
Competitive Bid Request.  Each Competitive Bid by a Lender must be received by
the CAF Agent by telecopy, in the form of Exhibit A-3 hereto, (i) in the case
of a Eurodollar Competitive Borrowing, not later than 9:30 a.m., New York City
time, three Business Days before a proposed Competitive Borrowing and (i) in
the case of a Fixed Rate Borrowing, not later than 9:30 a.m., New York City
time, on the day of a proposed Competitive Borrowing.  Multiple bids will be
accepted by the CAF Agent.  Competitive Bids that do not conform substantially
to the format of Exhibit A-3 may be rejected by the CAF Agent, and the CAF
Agent shall notify the Lender making such nonconforming bid of such rejection
as soon as practicable.  Each Competitive Bid shall refer to this Agreement and
specify (x) the principal amount (which shall be in a minimum principal amount
of $5,000,000 and in an integral multiple of $1,000,000 and which may equal the
entire principal amount of the Competitive Borrowing requested by the
applicable Borrower) of the Competitive Loan or Loans that the Lender is
willing to make to such Borrower, (y) the Competitive Bid Rate or Rates at
which the Lender is prepared





                                      -20-
<PAGE>   25
to make the Competitive Loan or Loans and (z) the Interest Period and the last
day thereof.  If any Lender invited to bid shall elect not to make a
Competitive Bid, such Lender shall so notify the CAF Agent by telecopy (I) in
the case of Eurodollar Competitive Loans, not later than 9:30 a.m., New York
City time, three Business Days before a proposed Competitive Borrowing, and
(II) in the case of Fixed Rate Loans, not later than 9:30 a.m., New York City
time, on the day of a proposed Competitive Borrowing; provided, however, that
failure by any Lender to give such notice shall not cause such Lender to be
obligated to make any Competitive Loan as part of such Competitive Borrowing.
A Competitive Bid submitted by a Lender pursuant to this paragraph (b) shall be
irrevocable.

       (c)    The CAF Agent shall notify the Borrower by telecopy, of all the
Competitive Bids made, the Competitive Bid Rate and the principal amount of
each Competitive Loan in respect of which such Competitive Bid was made and the
identity of the Lender that made each such bid by (i) in the case of a
Eurodollar Competitive Borrowing, not later than 10:00 a.m., New York City
time, three Business Days before a proposed Competitive Borrowing and (i) in
the case of a Fixed Rate Borrowing, not later than 10:00 a.m., New York City
time, on the day of a proposed Competitive Borrowing.  The CAF Agent shall send
a copy of all Competitive Bids to the Borrower for its records as soon as
practicable after the completion of the bidding process set forth in this
Section 2.03.

       (d)    A Borrower may in its sole and absolute discretion, subject only
to the provisions of this paragraph (d), accept or reject any or all
Competitive Bids referred to in paragraph (c) above.  Such Borrower shall
notify the CAF Agent by telephone, confirmed by telecopy in the form of a
Competitive Bid Accept/Reject Letter, whether and to what extent it has decided
to accept or reject any of or all the bids referred to in paragraph (c) above
by (i) in the case of a Eurodollar Competitive Borrowing, not later than 10:30
a.m., New York City time, three Business Days before a proposed Competitive
Borrowing and (i) in the case of a Fixed Rate Borrowing, not later than 10:30
a.m., New York City time, on the day of a proposed Competitive Borrowing;
provided, however, that (i) the failure by such Borrower to give such notice
shall be deemed to be a rejection of all the bids referred to in paragraph (c)
above, (i) such Borrower shall not accept a bid made at a particular
Competitive Bid Rate if it has decided to reject a bid made at a lower
Competitive Bid Rate, (i) the aggregate amount of the Competitive Bids accepted
by such Borrower shall not exceed the principal amount specified in the
Competitive Bid Request, (i) if such Borrower shall accept a bid or bids made
at a particular Competitive Bid Rate but the amount of such bid or bids shall
cause the total amount of bids to be accepted by such Borrower to exceed the
amount specified in the Competitive Bid Request, then such Borrower shall
accept a portion of such bid or bids in an amount equal to the amount specified
in the Competitive Bid Request less the amount of all other Competitive Bids
accepted with respect to such Competitive Bid Request, which acceptance, in the
case of multiple bids at such Competitive Bid Rate, shall be made pro rata in
accordance with the amount of each such bid at such Competitive Bid Rate, and
(i) except pursuant to clause (iv) above, no bid shall be accepted for a
Competitive Loan unless such Competitive Loan is in a minimum principal amount
of $5,000,000 and an integral multiple





                                      -21-
<PAGE>   26
of $1,000,000; provided further, however, that if a Competitive Loan must be in
an amount less than $5,000,000 because of the provisions of clause (iv) above,
such Competitive Loan may be for a minimum of $1,000,000 or any integral
multiple thereof, and in calculating the pro rata allocation of acceptances of
portions of multiple bids at a particular Competitive Bid Rate pursuant to
clause (iv) the amounts shall be rounded to integral multiples of $1,000,000 in
a manner which shall be in the discretion of the applicable Borrower.  A notice
given by a Borrower pursuant to this paragraph (d) shall be irrevocable.

       (e)    The CAF Agent shall promptly notify each bidding Lender (and the
Administrative Agent), by telecopy, whether or not its Competitive Bid has been
accepted (and if so, in what amount and at what Competitive Bid Rate) and each
successful bidder will thereupon become bound, subject to the other applicable
conditions hereof, to make the Competitive Loan in respect of which its bid has
been accepted.

       (f)    No Competitive Borrowing shall be requested or made hereunder if
after giving effect thereto any of the conditions set forth in clauses (i)
through (iv) of Section 2.01 would not be met.

       (g)    If either the Administrative Agent or CAF Agent shall elect to
submit a Competitive Bid in its capacity as a Lender, such party shall submit
such bid directly to the Borrower one quarter of an hour earlier than the
latest time at which the other Lenders are required to submit their bids to the
CAF Agent pursuant to paragraph (b) above.

       (h)    Each of the Borrowers and the CAF Agent shall deliver to the
Administrative Agent by telecopy copies of all notices delivered by it pursuant
to this Section 2.03 at the same times such notices are delivered hereunder.
All notices required by this Section 2.03 shall be given in accordance with
Section 8.01.

       (i)    A Competitive Bid Request shall not be made within five Business
Days after the date of any previous Competitive Bid which was accepted by a
Borrower pursuant to paragraph (d) above.

       SECTION 2.4.  STANDBY BORROWING PROCEDURE.  In order to request a
Standby Borrowing, a Borrower shall hand deliver or telecopy to the
Administrative Agent a duly completed Standby Borrowing Request in the form of
Exhibit A-5 (a) in the case of a Eurodollar Standby Borrowing, not later than
10:00 a.m., Houston time, three Business Days before such Borrowing, and (a) in
the case of an ABR Borrowing, not later than 10:00 a.m., Houston time, one
Business Day before such Borrowing.  No Fixed Rate Loan shall be requested or
made pursuant to a Standby Borrowing Request.  Such notice shall be irrevocable
and shall in each case specify (i) whether the Borrowing then being requested
is to be a Eurodollar Standby Borrowing or an ABR Borrowing; (i) the date of
such Standby Borrowing (which shall be a Business Day) and the amount thereof;
and (i) if such Borrowing is to be a Eurodollar Standby Borrowing, the Interest
Period with respect thereto, which shall not end after the Maturity Date.  If
no election as to the





                                      -22-
<PAGE>   27
Type of Standby Borrowing is specified in any such notice, then the requested
Standby Borrowing shall be an ABR Borrowing.  If no Interest Period with
respect to any Eurodollar Standby Borrowing is specified in any such notice,
then the Borrower shall be deemed to have selected an Interest Period of one
month's duration (subject, at all times prior to completion of syndication of
the Total Commitment, to the limitations set forth in the definition of
"Interest Period").  If a Borrower shall not have given notice in accordance
with this Section 2.04 of its election to refinance a Standby Borrowing prior
to the end of the Interest Period in effect for such Borrowing, then such
Borrower shall (unless such Borrowing is repaid at the end of such Interest
Period) be deemed to have given notice of an election to refinance such
Borrowing with an ABR Borrowing.  Notwithstanding any other provision of this
Agreement to the contrary, no Standby Borrowing shall be requested if the
Interest Period with respect thereto would end after the Maturity Date.  The
Administrative Agent shall promptly advise the Lenders of any notice given
pursuant to this Section 2.04 and of each Lender's portion of the requested
Borrowing.

       SECTION 2.5.  FEES.  (a)  Each Borrower agrees jointly and severally to
pay to each Lender, through the Administrative Agent, on each March 31, June
30, September 30 and December 31 (with the first payment being due on March 31,
1998) and on each date on which the Commitment of such Lender shall be
terminated as provided herein, a facility fee (a "FACILITY FEE"), at a rate per
annum equal to the Facility Fee Percentage from time to time in effect on the
amount of the sum of the unused Commitment of such Lender plus the principal
amount of Loans outstanding made by such Lender (without regard, in either
case, to any Competitive Loans made by any Lender), during the preceding
quarter (or other period commencing on the Effective Date or ending with the
Maturity Date or any date on which the Commitment of such Lender shall be
terminated).  All Facility Fees shall be computed on the basis of the actual
number of days elapsed in a year of 365 or 366 days, as the case may be.  The
Facility Fee due to each Lender shall commence to accrue on the Effective Date,
and shall cease to accrue on the earlier of the Maturity Date and the
termination of the Commitment of such Lender as provided herein.

       (b)    Each Borrower agrees jointly and severally to pay the
Administrative Agent, for its own account, the administrative fees provided for
in the Agent Fee Letter referred to in the Letter Agreement (the
"ADMINISTRATIVE FEES").

       (c)    Each Borrower agrees to pay the CAF Agent, for its own account,
the Auction Fees applicable to such Borrower.

       (d)    All Fees shall be paid on the dates due, in immediately available
funds, to the Administrative Agent for distribution, if and as appropriate,
among the Lenders, the Initial Underwriters or the Joint Lead Arrangers or to
the CAF Agent.  Once paid, none of the Fees shall be refundable under any
circumstances.

       SECTION 2.6.  REPAYMENT OF LOANS; EVIDENCE OF INDEBTEDNESS.  (a)  The
outstanding principal balance of each Loan shall be due and payable on the last
day of the Interest Period applicable thereto and on the Maturity Date.

       (b)    Each Lender shall maintain in accordance with its usual practice
an account or accounts evidencing the indebtedness to such Lender resulting
from each Loan made by such Lender from time to time, including the amounts of
principal and interest payable and paid to such Lender from time to time under
this Agreement.

       (c)    The Administrative Agent shall maintain accounts in which it will
record (i) the amount of each Loan made hereunder, the Type of each Loan made
and the Interest Period applicable thereto, (i) the amount of any principal or
interest due and payable or to become due and payable from each Borrower to
each Lender hereunder and (i) the amount of any sum received by the
Administrative Agent hereunder from each Borrower and each Lender's share
thereof.

       (d)    The entries made in the accounts maintained pursuant to
paragraphs (b) and (c) of this Section 2.06 shall, to the extent permitted by
applicable law, be prima facie evidence of the existence and amounts of the
obligations therein recorded; provided, however, that the failure of any Lender
or the Administrative Agent to maintain such accounts or any error therein
shall not in any manner affect the obligations of the Borrowers to repay the
Loans in accordance with their terms.

       SECTION 2.7.  INTEREST ON LOANS.  (a)  Subject to the provisions of
Section 2.08, the Loans comprising each Eurodollar Borrowing shall bear
interest (computed on the basis of the actual number of days elapsed over a
year of 360 days) at a rate per annum equal to the LIBO Rate for the Interest
Period in effect for such Borrowing plus the Applicable Margin from time to
time in effect and in the case of each Eurodollar Competitive Loan, the LIBO
Rate for the Interest Period in effect for such Borrowing plus the Competitive
Bid Margin offered by the Lender making such Loan and accepted by the
applicable Borrower pursuant to Section 2.03.

       (b)    Subject to the provisions of Section 2.08, the Loans comprising
each ABR Borrowing shall bear interest (computed on the basis of the actual
number of days elapsed over a year of 365 or 366 days, as the case may be, for
periods during which the Alternate Base Rate is determined by reference to the
Prime Rate and 360 days for other periods) at a rate per annum equal to the
Alternate Base Rate plus the Applicable Margin from time to time in effect.

       (c)    Subject to the provisions of Section 2.08, each Fixed Rate Loan
shall bear interest at a rate per annum (computed on the basis of the actual
number of days elapsed over a year of 360 days) equal to the fixed rate of
interest offered by the Lender making such Loan and accepted by the Borrower
pursuant to Section 2.03.





                                      -24-
<PAGE>   29
       (d)    Interest on each Loan shall be payable on each Interest Payment
Date applicable to such Loan except as otherwise provided in this Agreement.
The applicable LIBO Rate or Alternate Base Rate for each Interest Period or day
within an Interest Period, as the case may be, shall be determined by Chase,
and such determination shall be conclusive absent manifest error; provided that
Chase shall, upon request, provide to the applicable Borrower a certificate
setting forth in reasonable detail the basis for such determination.

       SECTION 2.8.  DEFAULT INTEREST.  If a Borrower shall default in the
payment of the principal of or interest on any Loan or any other amount
becoming due hereunder, whether by scheduled maturity, notice of prepayment,
acceleration or otherwise, such Borrower shall on demand from time to time from
the Administrative Agents pay interest, to the extent permitted by law, on such
defaulted amount up to (but not including) the date of actual payment (after as
well as before judgment) at a rate per annum (computed as provided in Section
2.07(b)) equal to the Alternate Base Rate plus the Applicable Margin for ABR
Loans plus 1%.

       SECTION 2.9.  ALTERNATE RATE OF INTEREST.  In the event, and on each
occasion, that on the day two Business Days prior to the commencement of any
Interest Period for a Eurodollar Borrowing the Administrative Agent shall have
determined (i) that dollar deposits in the principal amounts of the Eurodollar
Loans comprising such Borrowing are not generally available in the London
interbank market or (i) that reasonable means do not exist for ascertaining the
LIBO Rate, the Administrative Agent shall, as soon as practicable thereafter,
give telecopy notice of such determination to the Borrowers and the Lenders.
In the event of any such determination under clauses (i) or (ii) above, until
the Administrative Agent shall have advised the Borrowers and the Lenders that
the circumstances giving rise to such notice no longer exist, (x) any request
by a Borrower for a Eurodollar Competitive Borrowing pursuant to Section 2.03
shall be of no force and effect and shall be denied by the Administrative Agent
and (y) any request by a Borrower for a Eurodollar Standby Borrowing pursuant
to Section 2.04 shall be deemed to be a request for an ABR Borrowing.  In the
event the Required Lenders notify the Administrative Agent that the rates at
which dollar deposits are being offered will not adequately and fairly reflect
the cost to such Lenders of making or maintaining Eurodollar Loans during such
Interest Period, the Administrative Agent shall notify the applicable Borrower
of such notice and until the Required Lenders shall have advised the
Administrative Agent that the circumstances giving rise to such notice no
longer exist, any request by such Borrower for a Eurodollar Standby Borrowing
shall be deemed a request for an ABR Borrowing.  Each determination by the
Administrative Agent hereunder shall be made in good faith and shall be
conclusive absent manifest error; provided that the Administrative Agent,
shall, upon request, provide to the applicable Borrower a certificate setting
forth in reasonable detail the basis for such determination.

       SECTION 2.10.  TERMINATION AND REDUCTION OF COMMITMENTS.  (a)  The
Commitments shall be automatically terminated on the Maturity Date.





                                      -25-
<PAGE>   30
       (b)    Upon at least two Business Days' prior irrevocable written notice
to the Administrative Agent, the Borrowers, acting jointly, may at any time in
whole permanently terminate, or from time to time in part permanently reduce,
the Total Commitment; provided, however, that (i) each partial reduction of the
Commitments shall be in an integral multiple of $10,000,000 and in a minimum
principal amount of $10,000,000 and (i) no such termination or reduction shall
be made that would reduce the Total Commitment to an amount (1) less than the
aggregate outstanding principal amount of all Competitive Loans or (1) less
than $50,000,000, unless the result of such termination or reduction referred
to in this clause (2) is to reduce the Total Commitment to $0.  The
Administrative Agent shall advise the Lenders of any notice given pursuant to
this Section 2.10(c) and of each Lender's portion of any such termination or
reduction of the Total Commitment.

       (c)    Each reduction in the Total Commitment hereunder shall be made
ratably among the Lenders in accordance with their respective Commitments.  The
Borrowers shall pay to the Administrative Agent for the account of the Lenders,
on the date of each termination or reduction of the Total Commitment, the
Facility Fees on the amount of the Commitments so terminated or reduced accrued
through the date of such termination or reduction.

       SECTION 2.11.  PREPAYMENT.  (a)  Each Borrower shall have the right at
any time and from time to time to prepay any Standby Borrowing, in whole or in
part, upon giving telecopy notice (or telephone notice promptly confirmed by
telecopy) to the Administrative Agent:  (i) before 10:00 a.m., Houston time,
three Business Days prior to prepayment, in the case of Eurodollar Loans, and
(i) before 10:00 a.m., Houston time, one Business Day prior to prepayment, in
the case of ABR Loans; provided, however, that each partial prepayment shall be
in an amount which is an integral multiple of $10,000,000 and not less than
$10,000,000.  No prepayment may be made in respect of any Competitive
Borrowing.

       (b)    On the date of any termination or reduction of the Commitments
pursuant to Section 2.10, the Borrowers shall pay or prepay so much of the
Standby Borrowings as shall be necessary in order that the aggregate principal
amount of the Competitive Loans and Standby Loans outstanding will not exceed
the Total Commitment, after giving effect to such termination or reduction.

       (c)    Each notice of prepayment shall specify the prepayment date and
the principal amount of each Borrowing (or portion thereof) to be prepaid,
shall be irrevocable and shall commit the Borrower to prepay such Borrowing (or
portion thereof) by the amount stated therein on the date stated therein.  All
prepayments under this Section 2.11 shall be subject to Section 8.05 but
otherwise without premium or penalty.  All prepayments under this Section 2.11
shall be accompanied by accrued interest on the principal amount being prepaid
to the date of payment.

       SECTION 2.12.  RESERVE REQUIREMENTS; CHANGE IN CIRCUMSTANCES.  (a)
Notwithstanding any other provision herein, if after the date of this Agreement
any change in applicable law or regulation or in the interpretation or
administration thereof by any Governmental Authority charged with the
interpretation or administration thereof (whether or not having the force of
law) shall change the basis of taxation of payments to any Lender hereunder
(except for changes in respect of taxes on the overall net income of such
Lender or its lending office imposed by the jurisdiction in which such Lender's
principal executive office or lending office is located), or shall result in
the imposition, modification or applicability of any reserve, special deposit
or similar requirement against assets of, deposits with or for the account of
or credit extended by any Lender, or shall result in the imposition on any
Lender or the London interbank market of any other condition affecting this
Agreement, such Lender's Commitment or any Eurodollar Loan or Fixed Rate Loan
made by such Lender, and the result of any of the foregoing shall be to
increase the cost to such Lender of making or maintaining any Eurodollar Loan
or Fixed Rate Loan or to reduce the amount of any sum received or receivable by
such Lender hereunder (whether of principal, interest or otherwise) by an
amount deemed by such Lender to be material, then the applicable Borrower or,
if the foregoing circumstances do not relate to a particular Borrowing, the
Borrowers shall, upon receipt of the notice and certificate provided for in
Section 2.12(c), promptly pay to such Lender such additional amount or amounts
as will compensate such Lender for such additional costs incurred or reduction
suffered.  Notwithstanding the foregoing, no Lender shall be entitled to
request compensation under this paragraph with respect to any Competitive Loan
if the change giving rise to such request was applicable to such Lender at the
time of submission of the Competitive Bid pursuant to which such Competitive
Loan was made.

       (b)    If any Lender shall have determined that the adoption of any law,
rule, regulation or guideline arising out of the July 1988 report of the Basle
Committee on Banking Regulations and Supervisory Practices entitled
"International Convergence of Capital Measurement and Capital Standards," or
the adoption after the date hereof of any other law, rule, regulation or
guideline regarding capital adequacy, or any change in any of the foregoing or
in the interpretation or administration of any of the foregoing by any
Governmental Authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by any Lender (or any
lending office of such Lender) or any Lender's holding company with any request
or directive regarding capital adequacy (whether or not having the force of
law) of any such authority, central bank or comparable agency, has or would
have the effect of reducing the rate of return on such Lender's capital or on
the capital of such Lender's holding company, if any, as a consequence of this
Agreement, such Lender's Commitment or the Loans made by such Lender pursuant
hereto to a level below that which such Lender or such Lender's holding company
could have achieved but for such adoption, change or compliance (taking into
consideration such Lender's policies and the policies of such Lender's holding
company with respect to capital adequacy) by an amount deemed by such Lender to
be material, then from time to time such additional amount or amounts as will
compensate such Lender for any such reduction suffered will be paid by the
Borrowers to such Lender.  It is acknowledged that this Agreement is being
entered into by the Lenders on the understanding that the Lenders will not be
required to maintain capital against their Commitments





                                      -27-
<PAGE>   32
under currently applicable laws, regulations and regulatory guidelines.  In the
event the Lenders shall otherwise determine that such understanding is
incorrect, it is agreed that the Lenders will be entitled to make claims under
this paragraph (b) based upon market requirements prevailing on the date hereof
for commitments under comparable credit facilities against which capital is
required to be maintained.

       (c)    A certificate of each Lender setting forth such amount or amounts
as shall be necessary to compensate such Lender or its holding company as
specified in paragraph (a) or (b) above, as the case may be, and containing an
explanation in reasonable detail of the manner in which such amount or amounts
shall have been determined, shall be delivered to the applicable Borrower or
the Borrowers, as the case may be, and shall be conclusive absent manifest
error.  The Borrowers shall pay each Lender the amount shown as due on any such
certificate delivered by it within 10 days after its receipt of the same.  Each
Lender shall give prompt notice to the applicable Borrower of any event of
which it has knowledge, occurring after the date hereof, that it has determined
will require compensation by such Borrower pursuant to this Section; provided,
however, that failure by such Lender to give such notice shall not constitute a
waiver of such Lender's right to demand compensation hereunder.

       (d)    Failure on the part of any Lender to demand compensation for any
increased costs or reduction in amounts received or receivable or reduction in
return on capital with respect to any period shall not constitute a waiver of
such Lender's right to demand compensation with respect to such period or any
other period; provided, however, that no Lender shall be entitled to
compensation under this Section 2.12 for any costs incurred or reductions
suffered with respect to any date unless it shall have notified the applicable
Borrower that it will demand compensation for such costs or reductions under
paragraph (c) above not more than 90 days after the later of (i) such date and
(i) the date on which it shall have become aware of such costs or reductions.
The protection of this Section shall be available to each Lender regardless of
any possible contention of the invalidity or inapplicability of the law, rule,
regulation, guideline or other change or condition which shall have occurred or
been imposed.

       (e)    Each Lender agrees that it will designate a different lending
office if such designation will avoid the need for, or reduce the amount of,
such compensation and will not, in the reasonable judgment of such Lender, be
disadvantageous to such Lender.

       SECTION 2.13.  CHANGE IN LEGALITY.  (a)  Notwithstanding any other
provision herein, if any change in any law or regulation or in the
interpretation thereof by any Governmental Authority charged with the
administration or interpretation thereof shall make it unlawful for any Lender
to make or maintain any Eurodollar Loan or to give effect to its obligations as
contemplated hereby with respect to any Eurodollar Loan, then, by written
notice to the Borrowers and to the Agents, such Lender may:





                                      -28-
<PAGE>   33
              (i)    declare that Eurodollar Loans will not thereafter be made
       by such Lender hereunder, whereupon such Lender shall not submit a
       Competitive Bid in response to a request for Eurodollar Competitive
       Loans and any request for a Eurodollar Standby Borrowing shall, as to
       such Lender only, be deemed a request for an ABR Loan unless such
       declaration shall be subsequently withdrawn (any Lender delivering such
       a declaration hereby agreeing to withdraw such declaration promptly upon
       determining that such event of illegality no longer exists); and

              (ii)   require that all outstanding Eurodollar Loans made by it
       be converted to ABR Loans, in which event all such Eurodollar Loans
       shall be automatically converted to ABR Loans as of the effective date
       of such notice as provided in paragraph (b) below.

In the event any Lender shall exercise its rights under (i) or (ii) above, all
payments and prepayments of principal which would otherwise have been applied
to repay the Eurodollar Loans that would have been made by such Lender or the
converted Eurodollar Loans of such Lender shall instead be applied to repay the
ABR Loans made by such Lender in lieu of, or resulting from the conversion of,
such Eurodollar Loans.

       (b)    For purposes of this Section 2.13, a notice by any Lender shall
be effective as to each Eurodollar Loan, if lawful, on the last day of the
Interest Period currently applicable to such Eurodollar Loan; in all other
cases such notice shall be effective on the date of receipt.

       SECTION 2.14.  PRO RATA TREATMENT.  Except as provided below in this
Section 2.14 with respect to Competitive Borrowings and as required under
Sections 2.13 and 2.18, each Standby Borrowing, each payment or prepayment of
principal of any Standby Borrowing, each payment of interest on the Standby
Loans, each payment of the Facility Fees, each reduction of the Commitments and
each refinancing or conversion of any Borrowing with a Standby Borrowing of any
Type, shall be allocated pro rata among the Lenders in accordance with their
respective Commitments (or, if such Commitments shall have expired or been
terminated, in accordance with the respective principal amounts of their
outstanding Standby Loans).  Each payment of principal of any Competitive
Borrowing shall be allocated pro rata among the Lenders participating in such
Borrowing in accordance with the respective principal amounts of their
outstanding Competitive Loans comprising such Borrowing.  Each payment of
interest on any Competitive Borrowing shall be allocated pro rata among the
Lenders participating in such Borrowing in accordance with the respective
amounts of accrued and unpaid interest on their outstanding Competitive Loans
comprising such Borrowing.  For purposes of determining the available
Commitments of the Lenders at any time, each outstanding Competitive Borrowing
shall be deemed to have utilized the Commitments of the Lenders (including
those Lenders which shall not have made Loans as part of such Competitive
Borrowing) pro rata in accordance with such respective Commitments.  Each
Lender agrees that in computing such Lender's portion of any Borrowing to be
made hereunder, the Administrative Agent may, in its discretion, round each
Lender's percentage of such Borrowing to the next higher or lower whole dollar
amount.





                                      -29-
<PAGE>   34
       SECTION 2.15.  SHARING OF SETOFFS.  Each Lender agrees that if it shall,
through the exercise of a right of banker's lien, setoff or counterclaim, or
pursuant to a secured claim under Section 506 of Title 11 of the United States
Code or other security or interest arising from, or in lieu of, such secured
claim, received by such Lender under any applicable bankruptcy, insolvency or
other similar law or otherwise, or by any other means, obtain payment
(voluntary or involuntary) in respect of any Standby Loan or Loans as a result
of which the unpaid principal portion of its Standby Loans shall be
proportionately less than the unpaid principal portion of the Standby Loans of
any other Lender, it shall be deemed simultaneously to have purchased from such
other Lender at face value, and shall promptly pay to such other Lender the
purchase price for, a participation in the Standby Loans of such other Lender,
so that the aggregate unpaid principal amount of the Standby Loans and
participations in the Standby Loans held by each Lender shall be in the same
proportion to the aggregate unpaid principal amount of all Standby Loans then
outstanding as the principal amount of its Standby Loans prior to such exercise
of banker's lien, setoff or counterclaim or other event was to the principal
amount of all Standby Loans outstanding prior to such exercise of banker's
lien, setoff or counterclaim or other event; provided, however, that, if any
such purchase or purchases or adjustments shall be made pursuant to this
Section 2.15 and the payment giving rise thereto shall thereafter be recovered,
such purchase or purchases or adjustments shall be rescinded to the extent of
such recovery and the purchase price or prices or adjustment restored without
interest.  Each Borrower expressly consents to the foregoing arrangements and
agrees that any Lender holding a participation in a Standby Loan deemed to have
been so purchased may exercise any and all rights of banker's lien, setoff or
counterclaim with respect to any and all moneys owing by such Borrower to such
Lender by reason thereof as fully as if such Lender had made a Standby Loan in
the amount of such participation.

       SECTION 2.16.  PAYMENTS.  (a)  Each Borrower shall make each payment
(including principal of or interest on any Borrowing or any Fees or other
amounts) hereunder from an account in the United States not later than 10:00
a.m., Houston time, on the date when due in dollars to the Administrative Agent
at its offices at 707 Travis Street, 8-CBBN-N 96, Houston, Texas 77002, in
immediately available funds.

       (b)    Whenever any payment (including principal of or interest on any
Borrowing or any Fees or other amounts) hereunder shall become due, or
otherwise would occur, on a day that is not a Business Day, such payment may be
made on the next succeeding Business Day, and such extension of time shall in
such case be included in the computation of interest or Fees, if applicable.

       SECTION 2.17.  TAXES.  (a)  Any and all payments of principal and
interest on any Borrowings, or of any Fees or indemnity or expense
reimbursements by a Borrower hereunder ("BORROWER PAYMENTS") shall be made, in
accordance with Section 2.16, free and clear of and without deduction for any
and all current or future United States Federal, state and local taxes, levies,
imposts, deductions, charges or withholdings, and all liabilities with respect
to such





                                      -30-
<PAGE>   35
Borrower Payments, but only to the extent reasonably attributable to such
Borrower Payments, excluding (i) income taxes imposed on the net income of the
Administrative Agent, the CAF Agent or any Lender (or any transferee or
assignee thereof, including a participation holder (any such entity a
"TRANSFEREE")) and (i) franchise taxes imposed on the net income of the
Administrative Agent, the CAF Agent or any Lender (or Transferee), in each case
by the jurisdiction under the laws of which the Administrative Agent, the CAF
Agent or such Lender (or Transferee) is organized or doing business through
offices or branches located therein, or any political subdivision thereof (all
such nonexcluded taxes, levies, imposts, deductions, charges, withholdings and
liabilities, collectively or individually, "TAXES").  If any Borrower shall be
required to deduct any Taxes from or in respect of any sum payable hereunder to
any Lender (or any Transferee) or the Agents, (i) the sum payable shall be
increased by the amount (an "ADDITIONAL AMOUNT") necessary so that after making
all required deductions (including deductions applicable to additional sums
payable under this Section 2.17) such Lender (or Transferee) or Agent (as the
case may be) shall receive an amount equal to the sum it would have received
had no such deductions been made, (i) such Borrower shall make such deductions
and (i) such Borrower shall pay the full amount deducted to the relevant
Governmental Authority in accordance with applicable law.

       (b)    In addition, each Borrower shall pay to the relevant United
States Governmental Authority in accordance with applicable law any current or
future stamp or documentary taxes or any other excise or property taxes,
charges or similar levies that arise from any payment made hereunder or from
the execution, delivery or registration of, or otherwise with respect to, this
Agreement or the Letter Agreement ("OTHER TAXES").

       (c)    Each Borrower shall indemnify each Lender (or Transferee thereof)
and each Agent for the full amount of Taxes and Other Taxes with respect to
Borrower Payments paid by such Lender (or Transferee) or such Agent, as the
case may be, and any liability (including penalties, interest and expenses
(including reasonable attorney's fees and expenses)) arising therefrom or with
respect thereto, whether or not such Taxes or Other Taxes were correctly or
legally asserted by the relevant United States Governmental Authority.  A
certificate setting forth and containing an explanation in reasonable detail of
the manner in which such amount shall have been determined and the amount of
such payment or liability prepared by a Lender, the CAF Agent, or the
Administrative Agent on their behalf, absent manifest error, shall be final,
conclusive and binding for all purposes.  Such indemnification shall be made
within 30 days after the date the Lender (or Transferee) or any Agent, as the
case may be, makes written demand therefor.

       (d)    If a Lender (or Transferee) or any Agent shall become aware that
it is entitled to claim a refund from a United States Governmental Authority in
respect of Taxes or Other Taxes as to which it has been indemnified by a
Borrower, or with respect to which a Borrower has paid additional amounts,
pursuant to this Section 2.17, it shall promptly notify such Borrower of the
availability of such refund claim and shall, within 30 days after receipt of a
request by such Borrower, make a claim to such United States Governmental
Authority for such refund at such Borrower's expense.  If a Lender (or
Transferee) or any Agent receives a refund (including





                                      -31-
<PAGE>   36
pursuant to a claim for refund made pursuant to the preceding sentence) in
respect of any Taxes or Other Taxes as to which it has been indemnified by a
Borrower or with respect to which a Borrower had paid additional amounts
pursuant to this Section 2.17, it shall within 30 days from the date of such
receipt pay over such refund to such Borrower (but only to the extent of
indemnity payments made, or additional amounts paid, by such Borrower under
this Section 2.17 with respect to the Taxes or Other Taxes giving rise to such
refund), net of all out-of-pocket expenses of such Lender (or Transferee) or
such Agent and without interest (other than interest paid by the relevant
United States Governmental Authority with respect to such refund); provided,
however, that such Borrower, upon the request of such Lender (or Transferee) or
such Agent, agrees to repay the amount paid over to such Borrower (plus
penalties, interest or other charges) to such Lender (or Transferee) or such
Agent in the event such Lender (or Transferee) or such Agent is required to
repay such refund to such United States Governmental Authority.

       (e)    As soon as practicable, but in any event within 30 days, after
the date of any payment of Taxes or Other Taxes by a Borrower to the relevant
United States Governmental Authority, such Borrower will deliver to the
Administrative Agent, at its address referred to in Section 8.01, the original
or a certified copy of a receipt issued by such United States Governmental
Authority evidencing payment thereof.

       (f)    Without prejudice to the survival of any other agreement
contained herein, the agreements and obligations contained in this Section 2.17
shall survive the payment in full of the principal of and interest on all Loans
made hereunder.

       (g)    Each Lender or Agent (or Transferee) that is organized under the
laws of a jurisdiction other than the United States, any State thereof or the
District of Columbia (a "NON-U.S. LENDER" or "NON U.S. AGENT", as applicable)
shall deliver to the Borrowers and the Administrative Agent two copies of
either United States Internal Revenue Service Form 1001 or Form 4224, properly
completed and duly executed by such Non-U.S. Lender claiming complete exemption
from, or reduced rate of, United States Federal withholding tax on payments by
any Borrower under this Agreement.  Such forms shall be delivered by each Non-
U.S. Lender on or before the date it becomes a party to this Agreement (or, in
the case of a Transferee that is a participation holder, on or before the date
such participation holder becomes a Transferee hereunder) and on or before the
date, if any, such Non-U.S. Lender changes its applicable lending office by
designating a different lending office (a "NEW LENDING OFFICE").  In addition,
each Non-U.S. Lender shall deliver such forms promptly upon the obsolescence or
invalidity of any form previously delivered by such Non-U.S. Lender.
Notwithstanding any other provision of this Section 2.17(g), a Non-U.S. Lender
shall not be required to deliver any form pursuant to this Section 2.17(g) that
such Non-U.S. Lender is not legally able to deliver.

       (h)    A Borrower shall not be required to indemnify any Non-U.S. Lender
or Non-U.S. Agent (including any Transferee), or to pay any additional amounts
to any Non-U.S. Lender or Non-U.S. Agent (including any Transferee), in respect
of United States Federal, state or local





                                      -32-
<PAGE>   37
withholding tax pursuant to paragraph (a) or (c) above to the extent that (i)
the obligation to withhold amounts with respect to United States Federal, state
or local withholding tax existed on the date such Non-U.S. Lender became a
party to this Agreement (or, in the case of a Transferee that is a
participation holder, on the date such participation holder became a Transferee
hereunder) or, with respect to payments to a New Lending Office, the date such
Non-U.S. Lender designated such New Lending Office with respect to a Loan;
provided, however, that this clause (i) shall not apply to any Transferee or
New Lending Office that becomes a Transferee or New Lending Office as a result
of an assignment, participation, transfer or designation made at the request of
such Borrower; and provided, further, however, that this clause (i) shall not
apply to the extent the indemnity payment or additional amounts any Transferee,
or Lender (or Transferee) through a New Lending Office, would be entitled to
receive (without regard to this clause (i)) do not exceed the indemnity payment
or additional amounts that the person making the assignment, participation or
transfer to such Transferee, or Lender (or Transferee) making the designation
of such New Lending Office, would have been entitled to receive in the absence
of such assignment, participation, transfer or designation or (i) the
obligation to pay such additional amounts or such indemnity payments would not
have arisen but for a failure by such Non-U.S. Lender (including any
Transferee) to comply with the provisions of paragraph (g) above and (i) below.

       (i)    Any Lender (or Transferee) claiming any indemnity payment or
additional amounts payable pursuant to this Section 2.17 shall use reasonable
efforts (consistent with legal and regulatory restrictions) to file any
certificate or document reasonably requested in writing by a Borrower or to
change the jurisdiction of its applicable lending office if the making of such
a filing or change would avoid the need for or reduce the amount of any such
indemnity payment or additional amounts that may thereafter accrue and would
not, in the good faith determination of such Lender (or Transferee), be
otherwise disadvantageous to such Lender (or Transferee).

       (j)    Nothing contained in this Section 2.17 shall require any Lender
(or Transferee) or any Agent to make available to such Borrower any of its tax
returns (or any other information) that it deems to be confidential or
proprietary.

       (k)    Notwithstanding anything herein to the contrary, the
indemnification obligations under this Section shall, to the extent
practicable, be allocated between the Borrowers based upon their relative
liability for the interest, fee or other payments in respect of which such
indemnification obligations arise.

       SECTION 2.18.  ASSIGNMENT OF COMMITMENTS UNDER CERTAIN CIRCUMSTANCES.
In the event that any Lender shall have delivered a notice or certificate
pursuant to Section 2.12 or 2.13, or any Borrower shall be required to make
additional payments to any Lender under Section 2.17, the Borrowers shall have
the right, at their own expense, upon notice to such Lender and the Agents, to
require such Lender to transfer and assign without recourse (in accordance with
and subject to the restrictions contained in Section 8.04) all such Lender's
interests, rights and obligations contained hereunder to another financial
institution approved by the Agents and the Borrowers





                                      -33-
<PAGE>   38
(which approval shall not be unreasonably withheld) which shall assume such
obligations; provided that (i) no such assignment shall conflict with any law,
rule or regulation or order of any Governmental Authority and (i) the assignee
or the Borrowers, as the case may be, shall pay to the affected Lender in
immediately available funds on the date of such assignment the principal of and
interest accrued to the date of payment on the Loans made by it hereunder and
all other amounts accrued for its account or owed to it hereunder.


                                  ARTICLE III
                         REPRESENTATIONS AND WARRANTIES

       (d)    Since September 30, 1997, there has been no Material Adverse

against, or to the knowledge of such Borrower threatened against or affecting,
TUC or any of its Subsidiaries before any court or arbitrator or any
governmental body, agency or official in which there is a reasonable
possibility of an adverse decision which could materially adversely affect the
ability of such Borrower to pay its obligations hereunder or which in any
manner draws into question the validity of this Agreement.

       SECTION 3.7.  FEDERAL RESERVE REGULATIONS.        (a)  Neither such
Borrower nor any of its Subsidiaries is engaged principally, or as one of its
important activities, in the business of extending credit for the purpose of
purchasing or carrying Margin Stock.

       (b)    No part of the proceeds of any Loan will be used by such
Borrower, whether directly or indirectly, and whether immediately, incidentally
or ultimately, to purchase or carry Margin Stock (other than the American
Depositary Shares of TEG to be acquired in connection with the Acquisition) or
to refund indebtedness originally incurred for such purpose, or for any other
purpose which entails a violation of, or which is inconsistent with, the
provisions of the Margin Regulations.

       (c)    Not more than 25% of the value of the assets of any Borrower
subject to the restrictions of Section 5.09 are represented by Margin Stock.

       SECTION 3.8.  INVESTMENT COMPANY ACT; PUBLIC UTILITY HOLDING COMPANY

by the Borrowers of this Agreement and their respective obligations hereunder
do not violate any provision of such Act or any rule or regulation thereunder.

       SECTION 3.9.  NO MATERIAL MISSTATEMENTS.  No report, financial statement
or other written information furnished by or on behalf of such Borrower to the
Agents or any Lender pursuant to or in connection with this Agreement contains

be expected to result in a Material Adverse Change.  Neither such Borrower nor
any ERISA Affiliate has incurred any Withdrawal Liability that could result in
a Material Adverse Change.  Neither such Borrower nor any ERISA Affiliate has
received any notification that any Multiemployer Plan is in reorganization or
has been terminated within the meaning of Title IV of ERISA, which such
reorganization or termination could result in a Material Adverse Change, and no
Multiemployer Plan is reasonably expected to be in reorganization or to be
terminated where such reorganization or termination has resulted or can
reasonably be expected to result, through an increase in the contributions
required to be made to such Plan or otherwise, in a Material Adverse Change.

Significant Subsidiaries is a corporation duly incorporated, validly existing

prior to the date hereof, such Borrower and each of its Subsidiaries has
complied in all material respects with all Federal, state, local and other
statutes, ordinances, orders, judgments, rulings and regulations relating to
environmental pollution or to environmental or nuclear regulation or control,
except to the extent that failure to so comply could not reasonably be expected
to result in a Material Adverse Change.  Except as set forth in or contemplated
by such financial statements or other reports, neither such Borrower nor any of
its Subsidiaries has received notice of any material failure so to comply,
except where such failure could not reasonably be expected to result in a
Material Adverse Change.  Except as set forth in or contemplated by such
financial statements or other reports, the facilities of such Borrower or any
of its Subsidiaries, as the case may be, are not used to manage any hazardous
wastes, hazardous substances, hazardous materials, toxic substances, toxic

Change.  Except as set forth in or contemplated by such financial statements or
other reports, such Borrower is aware of no events, conditions or circumstances

good faith; and at all times maintain and preserve all property material to the
conduct of its business and keep such property in good repair, working order
and condition and from time to time make, or cause to be made, all needful and
proper repairs, renewals, additions, improvements and replacements thereto
necessary in order that the business carried on in connection therewith may be
properly conducted at all times.

       SECTION 5.3.  FINANCIAL STATEMENTS, REPORTS, ETC. TUC (and TU Electric

Enserch, as applicable, hereunder, and TUC will not in any event permit any
such consolidation, merger, sale, lease or transfer if any Default or Event of
Default shall have occurred and be continuing at the time of or after giving
effect to any such transaction.  Notwithstanding the foregoing, (a) neither TUC
nor any of its Subsidiaries will engage to a Substantial extent in businesses
other than those currently conducted by them, or in the case of Enserch, by
Enserch and other businesses reasonably related thereto,  (a) neither TUC nor
any of its Subsidiaries will acquire any Subsidiary or make any investment in

of assets permitted by Section 5.10(d).

Subsidiary will create or assume or permit to exist any Lien in respect of any
property or assets of any kind (real or personal, tangible or intangible) of
TUC or any Significant Subsidiary, or sell any such property or assets subject
to an understanding or agreement, contingent or otherwise, to repurchase such
property or assets, or sell, or permit any Significant Subsidiary to sell, any

       determined by the board of directors of TUC or such Significant
       Subsidiary, as the case may be) of the property theretofore subject to
       such Lien, whichever shall be lower, in each case at the time of such
       refunding or extension; provided that such Lien shall apply only to the
       same property theretofore subject to the same and fixed improvements
       constructed thereon; or

              (d)    sales subject to understandings or agreements to
       repurchase; provided that the aggregate sales price for all such sales

       such instrumentality's issuance of indebtedness, including without
       limitation industrial development bonds and pollution control bonds, on
       behalf of TUC or any Significant Subsidiary) made in any one calendar

                                      -49-
<PAGE>   54
with its agency hereunder; and (a) to distribute to each Lender copies of all
notices, financial statements and other materials delivered by the Borrowers
pursuant to this Agreement as received by the Administrative Agent.

       No Agent or any of its directors, officers, employees or agents shall be
liable as such for any action taken or omitted by any of them except for its or
his or her own gross negligence or willful misconduct, or be responsible for
any statement, warranty or representation herein or the contents of any
document delivered in connection herewith, or be required to ascertain or to
make any inquiry concerning the performance or observance by the Borrowers of
any of the terms, conditions, covenants or agreements contained in this
Agreement.  The Agents shall not be responsible to the Lenders for the due
execution, genuineness, validity, enforceability or effectiveness of this
Agreement or other instruments or agreements.  The Agents may deem and treat
the Lender which makes any Loan as the holder of the indebtedness resulting
therefrom for all purposes hereof until it shall have received notice from such
Lender, given as provided herein, of the transfer thereof.  The Agents shall in
all cases be fully protected in acting, or refraining from acting, in
accordance with written instructions signed by the Required Lenders and, except
as otherwise specifically provided herein, such instructions and any action or
inaction pursuant thereto shall be binding on all the Lenders.  Each of the
Agents shall, in the absence of knowledge to the contrary, be entitled to rely
on any instrument or document believed by it in good faith to be genuine and
correct and to have been signed or sent by the proper person or persons.  No
Agent or any of its directors, officers, employees or agents shall have any
responsibility to the Borrowers on account of the failure of or delay in
performance or breach by the other Agent or any Lender of any of its
obligations hereunder or to the other Agent or any Lender on account of the
failure of or delay in performance or breach by any other Lender, the other
Agent or any Borrower of any of their respective obligations hereunder or in
connection herewith.  Each of the Agents may execute any and all duties
hereunder by or through agents or employees and shall be entitled to rely upon
the advice of legal counsel selected by it with respect to all matters arising
hereunder and shall not be liable for any action taken or suffered in good
faith by it in accordance with the advice of such counsel.

       The Lenders hereby acknowledge that the Agents shall be under no duty to
take any discretionary action permitted to be taken by it pursuant to the
provisions of this Agreement unless it shall be requested in writing to do so
by the Required Lenders.

       Subject to the appointment and acceptance of a successor Agent as
provided below, either Agent may resign at any time by notifying the Lenders
and the Borrowers.  Upon any such resignation, the Required Lenders shall have
the right to appoint a successor Agent acceptable to the Borrowers.  If no
successor shall have been so appointed by the Required Lenders and shall have
accepted such appointment within 30 days after the retiring Agent gives notice
of its resignation, then the retiring Agent may, on behalf of the Lenders,
appoint a successor Agent, having a combined capital and surplus of at least
$500,000,000 or an Affiliate of any such bank.  Upon the acceptance of any
appointment as Agent hereunder by a successor bank, such successor





                                      -50-
<PAGE>   55
shall succeed to and become vested with all the rights, powers, privileges and
duties of the retiring Agent and the retiring Agent shall be discharged from
its duties and obligations hereunder.  After any Agent's resignation hereunder,
the provisions of this Article and Section 8.05 shall continue in effect for
its benefit in respect of any actions taken or omitted to be taken by it while
it was acting as Agent.

       With respect to the Loans made by it hereunder, each of the Agents, in
its individual capacity and not as an Agent shall have the same rights and
powers as any other Lender and may exercise the same as though it were not an
Agent, and each of the Agents and their Affiliates may accept deposits from,
lend money to and generally engage in any kind of business with the Borrowers
or any Subsidiary or other Affiliate thereof as if it were not an Agent.

       Each Lender agrees (i) to reimburse the Agents, on demand, in the amount
of its pro rata share (based on its Commitment hereunder or, if the Commitments
shall have been terminated, the amount of its outstanding Loans) of any
expenses incurred for the benefit of the Lenders in its role as Agent,
including counsel fees and compensation of agents and employees paid for
services rendered on behalf of the Lenders, which shall not have been
reimbursed by the Borrowers and (i) to indemnify and hold harmless each of the
Agents and any of its directors, officers, employees or agents, on demand, in
the amount of such pro rata share, from and against any and all liabilities,
taxes, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind or nature whatsoever which may be
imposed on, incurred by or asserted against it in any way relating to or
arising out of this Agreement or any action taken or omitted by it under this
Agreement to the extent the same shall not have been reimbursed by the
Borrowers; provided that no Lender shall be liable to any Agent for any portion
of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements resulting from the gross
negligence or willful misconduct of such Agent or any of its directors,
officers, employees or agents.  Each Lender agrees that any allocation made in
good faith by the Agents of expenses or other amounts referred to in this
paragraph between this Agreement and the Facility A Credit Agreement shall be
conclusive and binding for all purposes.

       Each Lender acknowledges that it has, independently and without reliance
upon the Agents or any other Lender and based on such documents and information
as it has deemed appropriate, made its own credit analysis and decision to
enter into this Agreement.  Each Lender also acknowledges that it will,
independently and without reliance upon the Agents or any other Lender and
based on such documents and information as it shall from time to time deem
appropriate, continue to make its own decisions in taking or not taking action
under or based upon this Agreement or any related agreement or any document
furnished hereunder or thereunder.

       SECTION 8.3.  BINDING EFFECT.  This Agreement shall become effective
when it shall have been executed by the Borrowers and each Agent and when the
Administrative Agent shall have received copies hereof (telecopied or
otherwise) which, when taken together, bear the signature of each Lender, and
thereafter shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns, except that the Borrowers shall
not have the right to assign any rights hereunder or any interest herein
without the prior consent of all the Lenders.

       SECTION 8.4.  SUCCESSORS AND ASSIGNS.  (a)  Whenever in this Agreement
any of the parties hereto is referred to, such reference shall be deemed to
include the successors and assigns of such party; and all covenants, promises
and agreements by or on behalf of any party that are contained in this
Agreement shall bind and inure to the benefit of its successors and assigns.

       (b)    Each Lender may assign to one or more assignees all or a portion
of its interests, rights and obligations under this Agreement (including all or
a portion of its Commitment and the Loans at the time owing to it); provided,
however, that (i) except in the case of an assignment to a Lender or an
Affiliate of such Lender, an assignment to a Federal Reserve Bank or an
assignment made at any time an Event of Default shall have occurred and be
continuing, the Borrowers and the Agents must give their prior written consent
to such assignment (which consent shall not be unreasonably withheld), (i) the
amount of the Commitment of the assigning Lender subject to each such
assignment (determined as of the date the Assignment and Acceptance with
respect to such assignment is delivered to the Administrative Agent) shall not
be less than $15,000,000, (i) each such assignment shall be of a constant, and
not a varying, percentage of all the assigning Lender's rights and obligations
under this Agreement, (i) the parties to each such assignment shall execute and
deliver to the Administrative Agent an Assignment and Acceptance, and a
processing and recordation fee of $3,000 (provided that, in the case of
simultaneous assignment of interests under one or more of this Agreement and
the Facility A Credit Agreement, the aggregate fee shall be $3,000), and (i)
the assignee, if it shall not be a Lender, shall deliver to the Administrative
Agent an Administrative Questionnaire.  Upon acceptance and recording pursuant
to Section 8.04(e), from and after the effective date specified in each
Assignment and Acceptance, which effective date shall be at least five Business
Days after the execution thereof unless otherwise agreed by the Administrative
Agent (the Borrowers to be given reasonable notice of any shorter period), (B)
the assignee thereunder shall be a party hereto and, to the extent of the
interest assigned by such Assignment and Acceptance, have the rights and
obligations of a Lender under this Agreement and (B) the assigning Lender
thereunder shall, to the extent of the interest assigned by such Assignment and
Acceptance, be released from its obligations under this Agreement (and, in the
case of an Assignment and Acceptance covering all or the remaining portion of
an assigning Lender's rights and obligations under this Agreement, such Lender
shall cease to be a party hereto (but shall continue to be entitled to the
benefits of Sections 2.12, 2.17 and 8.05 afforded to such Lender prior to its
assignment as well as to any Fees accrued for its account hereunder and not yet
paid)).  Notwithstanding the foregoing, any Lender assigning its rights and
obligations under this Agreement may retain any Competitive Loans made by it





                                      -53-
<PAGE>   58
outstanding at such time, and in such case shall retain its rights hereunder in
respect of any Loans so retained until such Loans have been repaid in full in
accordance with this Agreement.

       (c)    By executing and delivering an Assignment and Acceptance, the
assigning Lender thereunder and the assignee thereunder shall be deemed to
confirm to and agree with each other and the other parties hereto as follows:
(i) such assigning Lender warrants that it is the legal and beneficial owner of
the interest being assigned thereby free and clear of any adverse claim, (i)
except as set forth in (i) above, such assigning Lender makes no representation
or warranty and assumes no responsibility with respect to any statements,
warranties or representations made in or in connection with this Agreement, or
the execution, legality, validity, enforceability, genuineness, sufficiency or
value of this Agreement or any other instrument or document furnished pursuant
hereto or the financial condition of the Borrowers or the performance or
observance by the Borrowers of any obligations under this Agreement or any
other instrument or document furnished pursuant hereto; (i) such assignor and
such assignee represents and warrants that it is legally authorized to enter
into such Assignment and Acceptance; (i) such assignee confirms that it has
received a copy of this Agreement, together with copies of the most recent
financial statements delivered pursuant to Section 5.03 and such other
documents and information as it has deemed appropriate to make its own credit
analysis and decision to enter into such Assignment and Acceptance; (i) such
assignee will independently and without reliance upon the Agents, such
assigning Lender or any other Lender and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit decisions in taking or not taking action under this Agreement; (i) such
assignee appoints and authorizes each Agent to take such action as agent on its
behalf and to exercise such powers under this Agreement as are delegated to
such Agent by the terms hereof, together with such powers as are reasonably
incidental thereto; and (i) such assignee agrees that it will perform in
accordance with their terms all the obligations which by the terms of this
Agreement are required to be performed by it as a Lender.

       (d)    The Administrative Agent shall maintain at one of its offices in
the City of Houston a copy of each Assignment and Acceptance delivered to it
and a register for the recordation of the names and addresses of the Lenders,
and the Commitment of, and the principal amount of the Loans owing to, each
Lender pursuant to the terms hereof from time to time (the "REGISTER").  The
entries in the Register shall be conclusive in the absence of manifest error
and the Borrowers, the Agents and the Lenders may treat each person whose name
is recorded in the Register pursuant to the terms hereof as a Lender hereunder
for all purposes of this Agreement.  The Register shall be available for
inspection by each party hereto, at any reasonable time and from time to time
upon reasonable prior notice.

       (e)    Upon its receipt of a duly completed Assignment and Acceptance
executed by an assigning Lender and an assignee together with an Administrative
Questionnaire completed in respect of the assignee (unless the assignee shall
already be a Lender hereunder), the processing and recordation fee referred to
in paragraph (b) above and, if required, the written consent of the





                                      -54-
<PAGE>   59
Borrowers and the Agents to such assignment, the Administrative Agent shall (i)
accept such Assignment and Acceptance and (i) record the information contained
therein in the Register.

       (f)    Each Lender may without the consent of the Borrowers or the
Agents sell participations to one or more banks or other entities in all or a
portion of its rights and obligations under this Agreement (including all or a
portion of its Commitment and the Loans owing to it); provided, however, that
(i) such Lender's obligations under this Agreement shall remain unchanged, (i)
such Lender shall remain solely responsible to the other parties hereto for the
performance of such obligations, (i) each participating bank or other entity
shall be entitled to the benefit of the cost protection provisions contained in
Sections 2.12, 2.17 and 8.05 to the same extent as if it were the selling
Lender (and limited to the amount that could have been claimed by the selling
Lender had it continued to hold the interest of such participating bank or
other entity), except that all claims made pursuant to such Sections shall be
made through such selling Lender, and (i) the Borrowers, the Agents and the
other Lenders shall continue to deal solely and directly with such selling
Lender in connection with such Lender's rights and obligations under this
Agreement, and such Lender shall retain the sole right to enforce the
obligations of the Borrowers under this Agreement and to approve any amendment,
modification or waiver of any provision of this Agreement (other than
amendments, modifications or waivers (x) decreasing any fees payable hereunder
or the amount of principal of, or the rate at which interest is payable on, the
Loans, (y) extending any scheduled principal payment date or date fixed for the
payment of interest on the Loans or (z) extending the Commitments).

       (g)    Any Lender or participant may, in connection with any assignment
or participation or proposed assignment or participation pursuant to this
Section, disclose to the assignee or participant or proposed assignee or
participant any information relating to the Borrowers furnished to such Lender
by or on behalf of the Borrowers; provided that, prior to any such disclosure,
each such assignee or participant or proposed assignee or participant shall
execute an agreement whereby such assignee or participant shall agree (subject
to customary exceptions) to preserve the confidentiality of any such
information.

       (h)    The Borrowers shall not assign or delegate any rights and duties
hereunder without the prior written consent of all Lenders, and any attempted
assignment or delegation (except as a consequence of a transaction expressly
permitted under Section 5.09) by a Borrower without such consent shall be void.


       (i)    Any Lender may at any time pledge all or any portion of its
rights under this Agreement to a Federal Reserve Bank; provided that no such
pledge shall release any Lender from its obligations hereunder or substitute
any such Bank for such Lender as a party hereto.  In order to facilitate such
an assignment to a Federal Reserve Bank, each Borrower shall, at the request of
the assigning Lender, duly execute and deliver to the assigning Lender a
promissory note or notes evidencing the Loans made to such Borrower by the
assigning Lender hereunder.

<PAGE>   60
       SECTION 8.5.  EXPENSES; INDEMNITY.  (a)  The Borrowers agree to pay all
reasonable out-of-pocket expenses incurred by the Agents in connection with
entering into this Agreement or in connection with any amendments,
modifications or waivers of the provisions hereof (but only if such amendments,
modifications or waivers are requested by a Borrower) (whether or not the
transactions hereby contemplated are consummated), or incurred by the Agents or
any Lender in connection with the enforcement of their rights in connection
with this Agreement or in connection with the Loans made hereunder, including
the reasonable fees and disbursements of counsel for the Agents or, in the case
of enforcement following an Event of Default, the Lenders.

       (b)    The Borrowers agree to indemnify each Lender against any loss,
calculated in accordance with the next sentence, or reasonable expense which
such Lender may sustain or incur as a consequence of (a) any failure by such
Borrower to borrow or to refinance, convert or continue any Loan hereunder
(including as a result of such Borrower's failure to fulfill any of the
applicable conditions set forth in Article IV) after irrevocable notice of such
borrowing, refinancing, conversion or continuation has been given pursuant to
Section 2.03 or 2.04, (a) any payment, prepayment or conversion, or assignment
of a Eurodollar Loan or Fixed Rate Loan of such Borrower required by any other
provision of this Agreement or otherwise made or deemed made on a date other
than the last day of the Interest Period, if any, applicable thereto, (a) any
default in payment or prepayment of the principal amount of any Loan or any
part thereof or interest accrued thereon, as and when due and payable (at the
due date thereof, whether by scheduled maturity, acceleration, irrevocable
notice of prepayment or otherwise) or (d) the occurrence of any Event of
Default, including, in each such case, any loss or reasonable expense sustained
or incurred or to be sustained or incurred by such Lender in liquidating or
employing deposits from third parties, or with respect to commitments made or
obligations undertaken with third parties, to effect or maintain any Loan
hereunder or any part thereof as a Eurodollar Loan or a Fixed Rate Loan.  Such
loss shall include an amount equal to the excess, if any, as reasonably
determined by such Lender, of (i) its cost of obtaining the funds for the Loan
being paid, prepaid, refinanced, converted or not borrowed (assumed to be the
LIBO Rate or, in the case of a Fixed Rate Loan, the fixed rate of interest
applicable thereto) for the period from the date of such payment, prepayment,
refinancing or failure to borrow or refinance to the last day of the Interest
Period for such Loan (or, in the case of a failure to borrow or refinance the
Interest Period for such Loan which would have commenced on the date of such
failure) over (i) the amount of interest (as reasonably determined by such
Lender) that would be realized by such Lender in reemploying the funds so paid,
prepaid or not borrowed or refinanced for such period or Interest Period, as
the case may be.

       (c)    The Borrowers agree to indemnify the Agents, each Lender, each of
their Affiliates and the directors, officers, employees and agents of the
foregoing (each such person being called an "INDEMNITEE") against, and to hold
each Indemnitee harmless from, any and all losses, claims, damages, liabilities
and related expenses, including reasonable counsel fees and expenses, incurred
by or asserted against any Indemnitee arising out of (i)the consummation of the
transactions contemplated by this Agreement, including the Acquisition, (i) the
use of the proceeds of the





                                      -56-
<PAGE>   61
Loans or (i) any claim, litigation, investigation or proceeding relating to any
of the foregoing, whether or not any Indemnitee is a party thereto, including
any of the foregoing arising from the negligence, whether sole or concurrent,
on the part of any Indemnitee; provided that such indemnity shall not, as to
any Indemnitee, be available to the extent that such losses, claims, damages,
liabilities or related expenses (i) are determined by a final judgment of a
court of competent jurisdiction to have resulted from the gross negligence or
willful misconduct of such Indemnitee or (i) result from any litigation brought
by such Indemnitee against the Borrowers or by any Borrower against such
Indemnitee, in which a final, nonappealable judgment has been rendered against
such Indemnitee; provided further that each Borrower agrees that it will not,
nor will it permit any Subsidiary to, without the prior written consent of each
Indemnitee, settle, compromise or consent to the entry of any judgment in any
pending or threatened claim, action, suit or proceeding in respect of which
indemnification could be sought under the indemnification provisions of this
Section 8.05(c) (whether or not any Indemnitee is an actual or potential party
to such claim, action, suit or proceeding), unless such settlement, compromise
or consent does not include any statement as to an admission of fault,
culpability or failure to act by or on behalf of any Indemnitee and does not
involve any payment of money or other value by any Indemnitee or any injunctive
relief or factual findings or stipulations binding on any Indemnitee.

       (d)    The provisions of this Section shall remain operative and in full
force and effect regardless of the expiration of the term of this Agreement,
the consummation of the transactions contemplated hereby, the repayment of any
of the Loans, the invalidity or unenforceability of any term or provision of
this Agreement or any investigation made by or on behalf of any Agent or any
Lender.  All amounts due under this Section shall be payable on written demand
therefor.

       (e)    A certificate of any Lender or Agent setting forth any amount or
amounts which such Lender or Agent is entitled to receive pursuant to paragraph
(b) of this Section and containing an explanation in reasonable detail of the
manner in which such amount or amounts shall have been determined shall be
delivered to the appropriate Borrower and shall be conclusive absent manifest
error.

       SECTION 8.6.  RIGHT OF SETOFF.  If an Event of Default shall have
occurred and be continuing, each Lender is hereby authorized at any time and
from time to time, to the fullest extent permitted by law, to set off and apply
any and all deposits (general or special, time or demand, provisional or final)
at any time held and other indebtedness at any time owing by such Lender to or
for the credit or the account of the relevant Borrower against any of and all
the obligations of such Borrower now or hereafter existing under this Agreement
held by such Lender, irrespective of whether or not such Lender shall have made
any demand under this Agreement and although such obligations may be unmatured.
The rights of each Lender under this Section are in addition to other rights
and remedies (including other rights of setoff) which such Lender may have.





                                      -57-

       SECTION 8.7.  APPLICABLE LAW.  THIS AGREEMENT SHALL BE CONSTRUED IN
ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK.

       SECTION 8.8.  WAIVERS; AMENDMENT.  (a)  No failure or delay of either
Agent or any Lender in exercising any power or right hereunder shall operate as
a waiver thereof, nor shall any single or partial exercise of any such right or
power, or any abandonment or discontinuance of steps to enforce such a right or
power, preclude any other or further exercise thereof or the exercise of any
other right or power.  The rights and remedies of the Agents and the Lenders
hereunder are cumulative and are not exclusive of any rights or remedies which
they would otherwise have.  No waiver of any provision of this Agreement or
consent to any departure therefrom shall in any event be effective unless the
same shall be permitted by paragraph (b) below, and then such waiver or consent
shall be effective only in the specific instance and for the purpose for which
given.  No notice or demand on any Borrower or any Subsidiary in any case shall
entitle such party to any other or further notice or demand in similar or other
circumstances.

       (b)    Neither this Agreement nor any provision hereof may be waived,
amended or modified except pursuant to an agreement or agreements in writing
entered into by the Borrowers and the Required Lenders; provided, however, that
no such agreement shall (i) decrease the principal amount of, or extend the
maturity of or any scheduled principal payment date or date for the payment of
any interest on any Loan, or waive or excuse any such payment or any part
thereof, or decrease the rate of interest on any Loan, without the prior
written consent of each Lender affected thereby, (i) increase any Commitment or
decrease the Facility Fee of any Lender without the prior written consent of
such Lender, or (i) amend or modify the provisions of Section 2.14 or Section
8.04(h), the provisions of this Section or the definition of the "Required
Lenders", without the prior written consent of each Lender; provided further,
however, that no such agreement shall amend, modify or otherwise affect the
rights or duties of the Administrative Agent or the CAF Agent hereunder without
the prior written consent of the Administrative Agent or the CAF Agent, as the
case may be.  Each Lender shall be bound by any waiver, amendment or
modification authorized by this Section and any consent by any Lender pursuant
to this Section shall bind any assignee of its rights and interests hereunder.

       SECTION 8.9.  ENTIRE AGREEMENT.  THIS AGREEMENT (INCLUDING THE SCHEDULES
AND EXHIBITS HERETO) AND THE LETTER AGREEMENT CONSTITUTE A "LOAN AGREEMENT" AS
DEFINED IN SECTION 26.02(A) OF THE TEXAS BUSINESS AND COMMERCE CODE, AND
REPRESENT THE ENTIRE CONTRACT AMONG THE PARTIES RELATIVE TO THE SUBJECT MATTER
HEREOF AND THEREOF.  ANY PREVIOUS AGREEMENT, WHETHER WRITTEN OR ORAL, AMONG THE
PARTIES WITH RESPECT TO THE SUBJECT MATTER HEREOF, INCLUDING, WITHOUT
LIMITATION, THE EXISTING TU CREDIT AGREEMENTS, IS SUPERSEDED BY THIS AGREEMENT
AND THE LETTER AGREEMENT.  THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE
PARTIES.  NOTHING IN THIS AGREEMENT, EXPRESSED OR IMPLIED, IS INTENDED TO
CONFER UPON ANY PARTY OTHER





                                      -58-
<PAGE>   63
THAN THE PARTIES HERETO ANY RIGHTS, REMEDIES, OBLIGATIONS OR LIABILITIES UNDER
OR BY REASON OF THIS AGREEMENT.

       SECTION 8.10.  SEVERABILITY.  In the event any one or more of the
provisions contained in this Agreement should be held invalid, illegal or
unenforceable in any respect, the validity, legality and enforceability of the
remaining provisions contained herein shall not in any way be affected or
impaired thereby.  The parties shall endeavor in good-faith negotiations to
replace the invalid, illegal or unenforceable provisions with valid provisions
the economic effect of which comes as close as possible to that of the invalid,
illegal or unenforceable provisions.

       SECTION 8.11.  COUNTERPARTS.  This Agreement may be executed in two or
more counterparts, each of which shall constitute an original but all of which
when taken together shall constitute but one contract, and shall become
effective as provided in Section 8.03.

       SECTION 8.12.  HEADINGS.  Article and Section headings and the Table of
Contents used herein are for convenience of reference only, are not part of
this Agreement and are not to affect the construction of, or to be taken into
consideration in interpreting, this Agreement.

       SECTION 8.13.  INTEREST RATE LIMITATION.  (a)  Notwithstanding anything
herein to the contrary, if at any time the applicable interest rate, together
with all fees and charges which are treated as interest under applicable law
(collectively the "CHARGES"), as provided for herein or in any other document
executed in connection herewith, or otherwise contracted for, charged,
received, taken or reserved by any Lender, shall exceed the maximum lawful rate
(the "MAXIMUM RATE") which may be contracted for, charged, taken, received or
reserved by such Lender in accordance with applicable law, the rate of interest
payable on the Loans of such Lender, together with all Charges payable to such
Lender, shall be limited to the Maximum Rate.

       (b)    If the amount of interest, together with all Charges, payable for
the account of any Lender in respect of any interest computation period is
reduced pursuant to paragraph (a) of this Section and the amount of interest,
together with all Charges, payable for such Lender's account in respect of any
subsequent interest computation period, computed pursuant to Section 2.07,
would be less than the Maximum Rate, then the amount of interest, together with
all Charges, payable for such Lender's account in respect of such subsequent
interest computation period shall, to the extent permitted by applicable law,
be automatically increased to such Maximum Rate; provided that at no time shall
the aggregate amount by which interest paid for the account of any Lender has
been increased pursuant to this paragraph (b) exceed the aggregate amount by
which interest, together with all Charges, paid for its account has theretofore
been reduced pursuant to paragraph (a) of this Section.

       SECTION 8.14.  JURISDICTION; VENUE.  (a)  Each Borrower hereby
irrevocably and unconditionally submits, for itself and its property, to the
nonexclusive jurisdiction of any New York State court or Federal court of the
United States of America sitting in New York City,

and any appellate court from any thereof, in any action or proceeding arising
out of or relating to this Agreement, or for recognition or enforcement of any
judgment, and each of the parties hereto hereby irrevocably and unconditionally
agrees that all claims in respect of any such action or proceeding may be heard
and determined in such New York State or, to the extent permitted by law, in
such Federal court.  Each of the parties hereto agrees that a final judgment in
any such action or proceeding shall be conclusive and may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by law.
Subject to the foregoing and to paragraph (b) below, nothing in this Agreement
shall affect any right that any party hereto may otherwise have to bring any
action or proceeding relating to this Agreement against any other party hereto
in the courts of any jurisdiction.

       (b)    Each Borrower hereby irrevocably and unconditionally waives, to
the fullest extent it may legally and effectively do so, any objection which it
may now or thereafter have to the laying of venue of any suit, action or
proceeding arising out of or relating to this Agreement in any New York State
or Federal court.  Each of the parties hereto hereby irrevocably waives, to the
fullest extent permitted by law, the defense of an inconvenient forum to the
maintenance of such action or proceeding in any such court.

       SECTION 8.15.  CONFIDENTIALITY.  Each Lender shall use its best efforts
to hold in confidence all information, memoranda, or extracts furnished to such
Lender (directly or through the Agents) by the Borrowers hereunder or in
connection with the negotiation hereof; provided that such Lender may disclose
any such information, memoranda or extracts (i) to its accountants or counsel,
(i) to any regulatory agency having authority to examine such Lender, (i) as
required by any legal or governmental process or otherwise by law, (i) except
as provided in the last sentence of Section 5.03, to any person to which such
Lender sells or proposes to sell an assignment or a participation in its Loans
hereunder, if such other person agrees for the benefit of the Borrowers to
comply with the provisions of this Section and (i) to the extent that such
information, memoranda or extracts shall be publicly available or shall have
become known to such Lender independently of any disclosure by any Borrower
hereunder or in connection with the negotiation hereof.  Notwithstanding the
foregoing, any Lender may disclose the provisions of this Agreement and the
amounts, maturities and interest rates of its Loans to any purchaser or
potential purchaser of such Lender's interest in any Loan.

To the Lenders listed on
Schedule 2.01 of each
Credit Agreements referred to below
and from time to time party to such Credit Agreements

Ladies and Gentlemen:

       We advise you that we have acted as counsel to Texas Utilities Company,
a Texas Corporation ("TUC"), Texas Utilities Electric Company, a Texas
corporation ("TU ELECTRIC") and Enserch Corporation ("ENSERCH") in connection
with the 364-Day Competitive Advance and Revolving Credit Facility Agreement
and the 5-Year Competitive Advance and Revolving Credit Facility Agreement
(collectively, the "CREDIT AGREEMENTS"), each dated as of March 2, 1998, among,
TUC, TU Electric, Enserch Corporation, Chase Bank of Texas, National
Association, as Administrative Agent, The Chase Manhattan Bank, as Competitive
Advance Facility Agent, and the banks listed on Schedule 2.01 thereof (the
"LENDERS"), and have participated in the preparation of or have examined and
are familiar with (a) the current financial statements and reports filed by
TUC, TU Electric and Enserch with the Securities and Exchange Commission
pursuant to the Securities Exchange Act of 1934, as amended, (b) the Credit
Agreements, (C) the articles of incorporation and by-laws of TUC, TU Electric
and Enserch and (d) such other records and documents as we have deemed
necessary for the purposes of this opinion.

       As to those matters stated herein to be "to our knowledge" or "known to
us" such examination has been limited to discussions with and certificates from
officers of TUC and TU Electric and Enserch and we have not conducted any
independent investigation or verification





                          FACILITY B CREDIT AGREEMENT
<PAGE>   93
                                                                           D-1-2

or taken any action beyond such discussions and certificates, nor made any
search of the records of any Governmental Authority with respect to such
matters.

       Capitalized terms used in this opinion and not defined herein shall have
the respective meanings assigned thereto in the Credit Agreements.  This
opinion is delivered to you pursuant to Section 4.01(c) of the Credit
Agreements.

       We are members of the New York Bar and do not hold ourselves out as
experts on the laws of the State of Texas. As to all matters of Texas law
(including incorporation of TUC, TU Electric and Enserch, titles to properties,
franchises, licenses and permits) we have, with your consent, relied upon an
opinion of even date herewith delivered to you by Worsham, Forsythe &
Wooldridge, L.L.P., general counsel for TUC, TU Electric and Enserch.  While we
represent TUC and TU Electric on a regular basis, our engagement has been
limited to specific matters as to which we were consulted.  We have no direct
knowledge of the day-to-day affairs of TUC, TU Electric or Enserch and have not
reviewed generally their business affairs.  Accordingly, we are relying upon
representations of TUC, TU Electric and Enserch contained in the Credit
Agreements, in certificates furnished pursuant thereto, and in certificates
furnished to us by officers of TUC, TU Electric and Enserch.

       For purposes of the opinions expressed below, we have assumed (i) the
authenticity of all documents submitted to us as originals, (ii) the conformity
to the originals of all documents submitted to us as certified or photostatic
copies and the authenticity of the originals of such copies, (iii) the
genuineness of all signatures other than on behalf of TUC, TU Electric and
Enserch, (iv) the legal capacity of natural persons, (v) the power, corporate
or otherwise, of all parties other than TUC, TU Electric and Enserch to enter
into and to perform all of their obligations under such documents, and (vi) the
due authorization, execution and delivery of all documents by all parties other
than TUC, TU Electric and Enserch.

       Based on the foregoing, we are of the opinion that:

       1.  Each of TUC, TU Electric and Enserch (i) is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Texas, (ii) has all requisite power and authority to own its property and
assets and to carry on its business as now conducted, (iii) is qualified to do
business in every jurisdiction within the United States where such
qualification is





                          FACILITY B CREDIT AGREEMENT
<PAGE>   94
                                                                           D-1-3

required, except where the failure so to qualify would not result in a Material
Adverse Change, and (iv) has all requisite corporate power and authority to
execute, deliver and perform its obligations under the Credit Agreements and to
borrow funds thereunder.

       2.  The execution, delivery and performance by each of TUC, TU Electric
and Enserch of the Credit Agreements and the Borrowings by each of them
thereunder (collectively, the "TRANSACTIONS") and the consummation of the
Acquisition (i) have been duly authorized by all requisite corporate action and
(ii) will not (a) violate (1) any law, statute, rule or regulation presently
binding on or applicable to TUC, TU Electric or Enserch, or the articles of
incorporation, as amended, or by-laws of TUC, TU Electric or Enserch, (2) to
our knowledge, any order of any Governmental Authority presently applicable to
TUC, TU Electric or Enserch or (3) any provision of any indenture, agreement or
other instrument known to us to which TUC, TU Electric or Enserch or its
property is bound, (b) be in conflict with, result in a breach of or constitute
(alone or with notice or lapse of time or both) a default under any such
indenture, agreement or other instrument or (c) except as contemplated by the
UK Facility Agreement, result in the creation or imposition of any lien upon or
with respect to any property or assets of TUC, TU Electric or Enserch.

       3.  The Credit Agreements have been duly executed and delivered by TUC,
TU Electric and Enserch and constitute legal, valid and binding obligations of
TUC, TU Electric and Enserch enforceable against each of them in accordance
with their terms except as enforceability may be limited by bankruptcy,
insolvency, reorganization, moratorium or other similar laws affecting the
enforcement of creditors' rights generally and by general equitable principles
(regardless of whether such enforceability is considered in a proceeding in
equity or at law).

       4.  No action, consent or approval of, registration or filing with, or
any other action by, any Governmental Authority (including pursuant to the
Public Utility Holding Company Act of 1935, as amended) is required on the part
of TUC, TU Electric or Enserch in connection with the Transactions or the
Acquisition, except such as have been made or obtained and are in full force
and effect and, in the case of the Acquisition, (i) expiration or termination
of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of
1979 and (i) the filing by TUC of a registration statement on Form S-4 under
the Securities Act of 1933, as amended, relating to shares of common stock of
TUC to be issued in connection with the Acquisition, and action by

<PAGE>   95
                                                                           D-1-4

the Securities and Exchange Commission declaring said registration statement to
be effective under such Act.

       5.  (a)  None of TUC, TU Electric nor Enserch nor any of their
respective Subsidiaries is an "investment company" as defined in, or subject to
regulation under, the Investment Company Act of 1940, as amended, and (b) TUC,
TU Electric and Enserch and each of their respective Subsidiaries is exempt
from all provisions of the Public Utility Holding Company Act of 1935, as
amended, and the rules and regulations thereunder, except for Sections 9(a)(2)
and 33 of such Act and the rules and regulations thereunder, and the execution,
delivery and performance by each of TUC, TU Electric and Enserch of the Credit
Agreements and the consummation of the Acquisition do not violate any
provisions of such Act or any rule or regulation thereunder.

       6.  Except as described in the Annual Reports on Form 10-K for the year
ended December 31, 1996 and the Quarterly Reports on Form 10-Q for the quarters
ended March 31, 1997, June 30, 1997 and September 30, 1997, filed by TUC, TU
Electric and Enserch with the Securities and Exchange Commission and as set
forth in Schedule 3.06 to the Credit Agreements, to our knowledge there is no
action, suit, or proceeding at law or in equity or by or before any
Governmental Authority now pending or threatened against or affecting TUC, TU
Electric or Enserch (i) which involves the Transactions or (ii) as to which
there is a reasonable possibility of an adverse determination and which, if
adversely determined, could, individually or in the aggregate, result in a
Material Adverse Change.

       7.  To our knowledge, after due inquiry, the proposed use of the
proceeds of the Loans is in accordance with the Credit Agreements and, if so
used, will not violate the Margin Regulations.

       8.  We believe that a New York court would give effect to the provisions
of the Credit Agreements that state that they are to be construed in accordance
with New York law.

such examination of other documents and of certificates of public officials and
corporate officers of TUC, TU Electric and Enserch, and have made such other
legal and factual examinations and inquiries as we have deemed necessary or

conducted any independent investigation or verification or taken any action
beyond such discussions and certificates, nor made any search of the records of
any Governmental Authority with respect to such matters.

       For purposes of the opinions expressed below, we have assumed (i) the
authenticity of all documents submitted to us as originals, (ii) the conformity

order of any Governmental Authority presently applicable to TUC, TU Electric or

       5.  None of TUC, TU Electric nor Enserch nor any of their respective
Subsidiaries is an "investment company" as defined in, or subject to regulation
under, the Investment Company Act of 1940, as amended.  TUC, TU Electric and
each of their respective Subsidiaries is exempt from all provisions of the
Public Utility Holding Company Act of 1935, as amended, and rules and
regulations thereunder, except for Sections 9(a)(2) and 33 of such Act and
rules and regulations thereunder, and the execution, delivery and performance
by TUC, TU Electric and Enserch of the Credit Agreements and the consummation
of the Acquisition do not violate any provision of such Act or any rule or
regulation thereunder.

       6.  Except as described in the Annual Reports on Form 10-K for the year
ended December 31, 1996 and the Quarterly Reports on Form 10-Q for the quarters
ended March 31, 1997, June 30, 1997 and September 30, 1997, filed by TUC, TU
Electric and Enserch with the Securities and Exchange Commission and as set
forth in Schedule 3.06 to the Credit Agreements,

                                                                           D-2-4

to our knowledge there is no action, suit or proceeding at law or in equity or
by or before any Governmental Authority now pending or threatened against or
affecting TUC, TU Electric or Enserch (i) which involves the Transactions or
the Acquisition or (ii) as to which there is a reasonable possibility of an
adverse determination and which, if adversely determined, would, individually
or in the aggregate, result in a Material Adverse change.

       7.  To our knowledge, TUC, TU Electric and Enserch are not in violation
of any law, rule or regulation, or in default with respect to any judgment,
writ, injunction or decree of any Governmental Authority, where such violation
or default would result in a Material Adverse Change.

       8.  To our knowledge, after due inquiry, the proposed use of the
proceeds of the Loans is in accordance with the Credit Agreements, and, if so
used, will not violate the Margin Regulations.

       9.  We believe that a Texas court would give effect to the provisions of
the Credit Agreements that state that they are to be construed in accordance
with New York law; provided, however, that we render no opinion as to the
application of New York law that is contrary to a fundamental or public policy
of the State of Texas.

       We are members of the State Bar of Texas and do not purport to be
experts on, nor do we opine as to, the laws of any jurisdiction other than the
State of Texas and the federal laws of the United States.  To the extent that
the opinions hereinabove set forth involve the laws of the State of New York,
we have relied upon the opinion of even date herewith delivered by you by Reid
& Priest LLP, special counsel to TUC, TU Electric and Enserch.

       The foregoing opinions are limited to existing laws and we undertake no
obligation or responsibility to update or supplement this letter in response to
subsequent changes in the law or future events or circumstances affecting the
Transactions.  This letter is solely for the benefit of the named addressees
and may not be quoted in whole or in part or otherwise referred to in any
document or report and may not be furnished to any person without our prior
written consent, except that Reid & Priest LLP may rely hereon in connection
with their opinion being rendered pursuant to Section 4.01(c) of the Credit
Agreements.

specifically amended above, the Credit Agreements are and shall continue to be
in full force and effect and are hereby in all respects ratified and confirmed.
The execution, delivery and effectiveness of this Amendment shall not, except
as expressly provided herein, operate as a waiver of any right, power or remedy
of any Lender or any Agent under any Credit Agreement, nor constitute a waiver
of any provision of any Credit Agreement.

reasonable out-of-pocket expenses incurred by the Agents in connection with
entering into this Amendment (whether or not the transactions hereby

connection with the enforcement of their rights in connection with this
Amendment.

         SECTION 7.       EXECUTION IN COUNTERPARTS.  This Amendment may be
executed in any number of counterparts and by different parties hereto in
separate counterparts, each of which when so executed and delivered shall be
deemed to be an original and all of which taken together shall constitute but
one and the same agreement.

         SECTION 8.       GOVERNING LAW.  This Amendment shall be governed by,
and construed in accordance with, the laws of the State of New York.

         Reference is made to the 364-Day Competitive Advance and Revolving

or supplemented from time to time, the "CREDIT AGREEMENTS"), among Texas

Underwriters, ratably in accordance with their respective Commitments, as

                 (a)      25% of the Underwriting Fee shall be payable no later
         than the third Business Day following the date of the execution and
         delivery by the Borrowers of the Credit Agreements;

                 (b)      25% of the Underwriting Fee shall be payable upon the
         earlier to occur of (i) the thirtieth day following the date of the
         execution and delivery by the Borrowers of the Credit Agreements,
         provided, that the Offer Loan Commitments under the Facility A Credit
         Agreement shall not have been terminated in whole and (ii) the date
         the Initial Underwriters distribute to prospective Lenders any written
         offering materials (including, without limitation, any transaction

         unconditional.

         As used herein, "TOTAL MAXIMUM COMMITMENT" shall mean, with respect to
each Credit Agreement, the highest Total Commitment in effect under such Credit

contemplated by the Credit Agreements are consummated.  The Underwriting Fee
shall be paid in immediately available funds and shall be in addition to
reimbursement of out-of-pocket expenses of the Joint Lead Arrangers and the

discretion, share all or a portion of any of the Underwriting Fee with any of
the other Lenders.

         It is understood and agreed that this Fee Letter shall not constitute
or give rise to any obligation to provide any financing; such an obligation
will arise only to the extent provided in the Credit Agreements.  This Fee
Letter may not be amended or waived except by an instrument in writing signed

                 a date no earlier than the date of this Agreement by an
                 officer of the Primary Borrower who is at such time duly
                 authorised to execute or certify such documents on behalf of

                 than could reasonably be expected to be obtained in a
                 comparable transaction with a person unconnected with the
                 Group;

         (q)     references to "HOLDING COMPANY", save as otherwise defined,

2.       THE COMMITMENTS

2.1      THE FACILITIES

         The Banks, relying upon each of the representations and warranties in
         clause 9 and upon and subject to the conditions hereof, agree to make
         available:

         (a)     to the Primary Borrower, the Acquisition Facility in the
                 principal sum of L.1,775,000,000;

         (b)     to the Primary Borrower, the Interim Facility in the principal
                 sum of L.1,150,000,000;

         (c)     to the Revolving Credit Facility Borrowers, the Revolving
                 Credit Facility in the principal sum of L.700,000,000
                 (including the stand-alone facility for REC provided for in
                 clause 24.5).

         The obligations of each Bank under this Agreement shall be to
         participate in each Advance in the proportion which its Commitment in
         respect of the relevant Facility bears to the Total Commitments in
         respect of the relevant Facility but so that no Bank shall be under
         any obligation to participate in an Advance if and to the extent its
         Commitment in respect of the relevant Facility would thereby be
         exceeded.

2.2      FINANCE PARTIES' OBLIGATIONS SEVERAL

         The obligations of each Finance Party under this Agreement are
         several; the failure of any Finance Party to perform such obligations
         shall not relieve any other Finance Party or any Borrower of any of
         their respective obligations or liabilities under this Agreement nor
         shall any Finance Party be responsible for the obligations of any
         other Finance Party under this Agreement.

2.3      FINANCE PARTIES' INTERESTS SEVERAL

         Notwithstanding any other term of this Agreement (but without
         prejudice to the provisions of this Agreement relating to or requiring
         action by the Majority Banks) the interests of the Finance Parties are
         several and the amount due to each of the Finance Parties (for its own
         account) is a separate and independent debt.  Without prejudice to any
         other provision of this Agreement (including any requirement for
         action to be approved or instigated by, or with the consent or
         approval of, the Majority Banks) each of the Finance Parties shall
         have the right to protect and enforce its rights to amounts which have
         become due and payable to it under this Agreement and it shall not be
         necessary for any other Finance Party to be joined as an additional
         party in any proceedings for this purpose.


3.       THE CONDITIONS

3.1      DOCUMENTS AND EVIDENCE

         No Advance may be made until the Unconditional Date and until the
         Facility Agent, or its duly authorised representative, shall have
         received the documents and evidence specified in Parts A and B of
         Schedule 3, in each case in form and substance satisfactory to the
         Facility Agent which the Facility Agent shall, once it is so
         satisfied, confirm in writing to the Primary Borrower.

                                     - 29 -




3.2      GENERAL CONDITIONS PRECEDENT

         Subject to clause 3.3, in respect of each Facility, the obligation of
         each Bank to contribute to an Advance is subject to the further
         conditions that at the date of each Drawdown Notice and on each
         Drawdown Date:

         (a)     the applicable representations and warranties set out in
                 clause 9 are true and correct on and as of each such date as
                 if each were made with respect to the facts and circumstances
                 existing at such date; and

         (b)     no Default shall have occurred and be continuing or would
                 result from the making of such Advance,

         but this clause 3.2(b) shall not prevent the rollover of an existing
         Revolving Credit Advance (without increasing the amount thereof) for a
         Maturity Period of no more than one month at any time when no Event of
         Default has occurred and is continuing.

3.3      CONDITIONS RELATING TO OFFER ADVANCES DURING CERTAIN FUNDS PERIOD

         To ensure that the Primary Borrower has resources available to advance
         to Finco 2 funds to on-lend to Bidco funds to enable Bidco to fulfil
         its obligations in respect of the Offer, the Banks agree that, in
         relation to each Offer Advance requested and to be advanced during the
         Certain Funds Period, clause 3.2 shall not be applicable and subject
         to satisfying the requirements of clause 3.1 and to providing the
         appropriate Drawdown Notice at the appropriate time in accordance with
         this Agreement, the only further condition to the obligations of the
         Banks to make such Offer Advance is that at the date of each Drawdown
         Notice and on each Drawdown Date no Major Default shall have occurred
         and be continuing or would result from the making of such Offer
         Advance.

         It is further confirmed, for the avoidance of doubt, that the
         commitment in this clause 3.3 operates notwithstanding any contrary
         provisions of the Finance Documents and that no Bank shall be entitled
         to rescind this Agreement or to fail to contribute to an Offer Advance
         where the conditions in clause 3.3 are fulfilled.

3.4      WAIVER OF CONDITIONS PRECEDENT

         The conditions specified in this clause 3 are inserted solely for the
         benefit of the Banks and may be waived on their behalf in whole or in
         part and with or without conditions by the Facility Agent acting on
         the instructions of the Majority Banks in respect of any Advance.


4.       ADVANCES UNDER THE FACILITIES

                          Termination Date;

                                     - 30 -




                 (ii)     the amount of the proposed Advance, which shall be of
                          L.10,000,000 (or any larger sum which is an integral
                          multiple of L.5,000,000) or, if less, the Available
                          Facility Amount in respect of the Acquisition
                          Facility or the Interim Facility (as the case may be)
                          on the relevant Drawdown Date;

                 (iii)    subject to clause 4.1(c), the first Interest Period
                          relating to the Advance in question (in the case of
                          the Acquisition Facility, (being a period of 1, 2, 3
                          or 6 months or such other duration as the Primary
                          Borrower and the Banks may agree, and in the case of
                          the Interim Facility being one month) will begin on
                          the proposed Drawdown Date and end on a Banking Day
                          which is or precedes the Final Repayment Date (and in
                          the case of Interim Advances, the relevant Available
                          Commitment Termination Date); and

                 (iv)     the account to which the proceeds of the proposed
                          Advance are to be paid.

                 There shall be no more than 10 Acquisition Advances and 10
                 Interim Advances outstanding at any time and not more than one
                 Acquisition Advance and/or Interim Advance may be made in any
                 period of 5 consecutive Banking Days.

         (c)     Interest Periods at time of syndication

                 The Primary Borrower shall until the Syndication Date select
                 one month Interest Periods or such other periods as the
                 Facility Agent and the Primary Borrower agree as being
                 necessary to effect the transfer of participations following
                 syndication.

         (d)     Acquisition Facility

                 No Interim Advances shall be made unless and until the
                 Acquisition Facility has been drawn down in full.

         (e)     Loan Note Obligations

                 If the Loan Note Obligations as at the Available Commitment
                 Termination Date for the Acquisition Facility are in excess of
                 L.50,000,000, the Loan Note Facility shall be available until
                 the Final Repayment Date and Advances may be drawn down by the
                 Primary Borrower from time to time under the Loan Note
                 Facility to be on-lent to Finco 2 to be used by it to on-lend
                 to Bidco to be used to fund Loan Note Obligations. To the
                 extent that, by reason of the minimum drawdown requirements
                 set out above, an Advance drawn down under the Loan Note
                 Facility exceeds the then outstanding Loan Note Obligations,
                 any excess shall be retained by the Primary Borrower and paid
                 into the Loan Note Collateral Account which shall be a blocked
                 account maintained by the Security Agent.  To the extent that
                 the aggregate Loan Note Obligations as at the Available
                 Commitment Termination Date for the Acquisition Facility are
                 not in excess of L.50,000,000 the Loan Note Facility shall not
                 come into existence, but Advances may be drawn down by the
                 Primary Borrower under the Acquisition Facility or if there is
                 no further available Commitment under that Facility, under the
                 Interim Facility to be on-lent to Finco 2 to be used by it to
                 on-lend to Bidco to be used to fund Loan Note Obligations.
                 Any Advance drawn down under the Acquisition Facility or
                 Interim Facility shall be drawn down by the Primary Borrower
                 and paid into the Loan Note Collateral Account. The Security
                 Agent shall permit the Primary Borrower to draw amounts from
                 the Loan Note Collateral Account from time to time:

                 (i)      to the extent of Loan Note Obligations then due, to
                          be on-lent to Finco 2 to be used by it to on-lend to
                          Bidco to be used by Bidco to fund such Loan Note
                          Obligations; provided that
<PAGE>   32
                                     - 31 -




                 (ii)     at the relevant time, no Event of Default shall have
                          occurred which has not been remedied or waived to the
                          reasonable satisfaction of the Security Agent.

                 The Loan Note Collateral Account shall not be a trust account
                 and sums standing to its credit from time to time shall be
                 charged by way of fixed charge under the Debenture and
                 available to the Security Agent by way of security.

         (f)     Cancellation on Available Commitment Termination Date

                 If there is any Available Facility Amount outstanding in
                 relation to the Acquisition Facility or the Interim Facility
                 on the Available Commitment Termination Date in respect of
                 such Facility, such Available Facility Amount (other than the
                 Loan Note Facility as at such date) shall thereupon be
                 automatically cancelled and no further Advance may be made
                 under the Acquisition Facility or the Interim Facility other
                 than the Loan Note Facility.  If a Loan Note Facility has not
                 been established, the Primary Borrower may draw down on the
                 Acquisition Facility or, if it has been drawn down in full the
                 Interim Facility on the day before the relevant Available
                 Commitment Termination Date to fund the Loan Note Collateral
                 Account with sufficient funds to meet its actual or contingent
                 Loan Note Obligations as at such date.

4.2      THE REVOLVING CREDIT FACILITY

                 Citibank International plc as agent, Barclays Bank PLC and
                 Midland Bank plc so that it is no longer available for
                 drawing, Revolving Advances shall be made to the relevant
                 Revolving Credit Facility Borrower following receipt by the

                 completed Drawdown Notice relating to the Revolving Credit
                 Facility not later than 11 a.m. two Banking Days before the
                 proposed Drawdown Date (which, in respect of the first
                 Revolving Advance to be made for the purpose of refinancing
                 certain Target Group Borrowed Money will be the Unconditional

                          Day falling prior to the Available Commitment
                          Termination Date;

                 (ii)     the amount of the Revolving Advance, which shall be
                          of L.10,000,000 or any larger sum which is an
                          integral multiple of L.5,000,000 or, if less, the
                          Available Facility Amount in respect of the Revolving

                 There shall be no more than 10 Revolving Advances outstanding
                 at any time, and not more than one Revolving Advance may be
                 made in any period of 5 consecutive Banking Days.

         (d)     First drawdown

                 No Revolving Advance may be made unless and until the first
                 Acquisition Advance  could have been drawn down (but for the
                 delayed settlement of acceptances of the Offer).

         (e)     Calculation of Available Commitment

                 For the purpose of calculating the Available Commitment, the
                 Outstanding Contingent Liabilities under a Letter of Credit

                 subject to recalculation by the Facility Agent in accordance
                 with the definition of "Sterling Amount" and clause 4.11
                 (Currency Fluctuations).

                 the Total Commitments under the Revolving Credit Facility

                 Commitment Termination Date in respect of such Facility and no
                 Advance may be drawn by the Revolving Credit Facility
                 Borrowers under the Revolving Credit Facility thereafter.

         Subject to the provisions of this Agreement, the Issuing Bank will
         Issue a Letter of Credit specified in a Drawdown Notice at the request
         of a Revolving Credit Facility Borrower, if the Agent has received the
         Drawdown Notice for a Letter of Credit in the form set out in Part C
         of Schedule 2 (Letters of Credit) signed on behalf of that Borrower
         not later than 11.00 am five Banking Days prior to the proposed Issue
         Date: and

                 Final Repayment Date;

         (b)     the face value of each Letter of Credit is a minimum Sterling
                 Amount of L.1,000,000;

         (c)     the Expiry Date falls on or before the earlier of 12 months
                 from the Issue Date and the Final Repayment Date;

         (d)     the Issuing Bank and (if different) the Facility Agent has
                 agreed its terms;

         (e)     the Sterling Amount of the Letter of Credit requested does not
                 exceed the Available Facility Amount in respect of the
                 Revolving Credit Facility;

         (f)     after such Issue, there will be no more than ten Letters of
                 Credit outstanding;

         (g)     no order, judgment or decree of any Governmental Entity or
                 arbitrator shall be outstanding which by its terms purports to
                 enjoin or restrain the Issuing Bank from Issuing such Letter
                 of Credit, nor shall any requirement of law applicable to the
                 Issuing Bank or any request or directive (whether or not
                 having the force of law) from any Governmental Entity with
                 jurisdiction over the Issuing Bank prohibit, or request that
                 the Issuing Bank refrain from, the Issuance of Letters of
                 Credit generally or such Letter
<PAGE>   34
                                     - 33 -



                 of Credit in particular or shall impose upon the Issuing Bank
                 with respect to such Letter of Credit any restriction, reserve
                 or capital requirement (for which the Issuing Bank is not
                 otherwise compensated hereunder and which is not in effect on
                 the date of this Agreement), or shall impose upon the Issuing
                 Bank any unreimbursed loss, cost or expense which was not
                 applicable on the date of this Agreement and which the Issuing
                 Bank in good faith deems material to it;

         (h)     the currency in which the relevant Letter of Credit is to be
                 denominated is, in the opinion of the Issuing Bank, not likely
                 to be subject to undue fluctuation against Sterling and is
                 likely to be freely convertible and available in sufficient
                 amounts to enable the Issuing Bank to discharge its
                 obligations as they fall due;

         (i)     the Issuing Bank has approved (and been approved by) the
                 relevant beneficiary; and

         (j)     the total Sterling Amount of all Outstanding Contingent
                 Liabilities under all Letters of Credit then outstanding would
                 not exceed L.250,000,000.

4.4      ADVANCES GENERALLY

         (a)     A Drawdown Notice (or notice purporting to be such) shall only
                 be effective if it complies with this Agreement and only upon
                 actual receipt by the Facility Agent and, once given, shall be
                 irrevocable.

         (b)     As soon as practicable after receipt of each Drawdown Notice
                 complying with this Agreement the Facility Agent shall notify
                 each Bank of such receipt and of the date on which the
                 proposed Advance is to be made and of the relevant Interest
                 Period or, as the case may be, the relevant Maturity Period
                 and each Bank shall on such Drawdown Date or, the case may be,
                 on the first day of the relevant Interest Period participate
                 in such Advance by making available to the Facility Agent its
                 portion of such Advance in accordance with clause 8.2.

4.5      APPLICATION OF PROCEEDS

         Without prejudice to the Borrowers' obligations under clause 10.2(a),
         none of the Finance Parties shall have any responsibility for the
         application of the proceeds of any Advance by any Borrower.

4.6      LETTERS OF CREDIT

         (a)     Issuing Bank as principal: the Issuing Bank will act as
                 principal of each Letter of Credit Issued by it and each Bank
                 will counter-indemnify the Issuing Bank in respect of the
                 Outstanding Contingent Liabilities thereunder in the relevant
                 Proportion;

         (b)     Borrowers' Authorisation and Indemnity: each Borrower
                 unconditionally and irrevocably:

                 (i)      authorises the Issuing Bank to comply with any demand
                          which appears to be duly made by a third party in
                          respect of a Letter of Credit without any further
                          reference to the relevant Borrower on the terms set
                          out in Schedule 7 (Terms of Borrowers' Indemnity);

                 (ii)     agrees that its authorisation under clause 4.6(b)(i)
                          and its indemnity under clause 4.6(b)(iv) shall
                          remain in full force and effect and shall not be
                          discharged until such date as the Facility Agent
                          (acting on the instructions of the Issuing Bank)
                          shall notify the relevant Borrower that it is
                          satisfied (acting reasonably) that the Issuing Bank
                          remains under no liability (actual or contingent) in
                          respect of any Letter of Credit;
<PAGE>   35
                                     - 34 -




                 (iii)    agrees that each Letter of Credit is Issued subject
                          to and with the benefit of the provisions of Schedule
                          7 (Terms of Borrowers' Indemnity); and

                 (iv)     if a Finance Party suffers any liabilities, damages,
                          costs, expenses, losses and charges whatsoever in
                          relation to or arising out of any Letter of Credit
                          Issued or clause 4.7 (Banks' Guarantee and
                          Indemnity), the benefit of Schedule 7 (Terms of
                          Borrowers' Indemnity) shall extend to such Finance
                          Party.  A Borrower may finance a payment under such
                          indemnity by drawing down a Revolving Advance if it
                          is then entitled to do so in accordance with the
                          terms of this Agreement.

4.7      BANKS' GUARANTEE AND INDEMNITY

         Each Bank hereby irrevocably and unconditionally:

         (a)     subject to clause 4.7(b), guarantees to and indemnifies on the
                 terms set out in Schedule 8 (Terms of Interbank Guarantee and
                 Indemnity) the Issuing Bank severally in its Proportion and on
                 demand by the Issuing Bank, the due and punctual performance
                 by any relevant Borrower of all its obligations in respect of
                 each Letter of Credit Issued by the Issuing Bank;

         (b)     if it is not permitted by its constitutional documents or any
                 applicable law to grant guarantees, agrees that, upon any
                 failure of a relevant Borrower to make timely payment of any
                 amount due in respect of a Letter of Credit, such Bank shall
                 take (and upon the occurrence of an Event of Default specified
                 in clauses 12.1(e) to (n) (Events of Default) (or any event
                 occurs which under the applicable law of any relevant
                 jurisdiction has an analogous, similar or equivalent effect to
                 any such events) shall be deemed to have taken without any
                 further action, as of the Issue Date of each outstanding
                 Letter of Credit), an undivided participating interest from
                 the Issuing Bank in each Letter of Credit outstanding at such
                 time in a proportion equal to such Bank's Proportion.  Each
                 Bank shall hold the Issuing Bank harmless and indemnify the
                 Issuing Bank for such Bank's proportionate share of any
                 drawing under any Letter of Credit in which it has taken an
                 undivided participating interest under this clause 4.7;

         (c)     as a separate and independent stipulation agrees that any sum
                 of money intended to be the subject of the guarantee in clause
                 4.7(a), and subject to clause 4.7(b) and Schedule 8 (Terms of
                 Interbank Guarantee and Indemnity), shall be recoverable from
                 it (in its Proportion) as sole principal debtor even if such
                 sum would not be recoverable from any relevant Borrower by
                 reason of any legal limitation, disability or incapacity or
                 liquidation of any of them or any other fact or circumstance
                 (whether known to the Issuing Bank or not) but which would
                 have been recoverable from such Bank if it were the sole or
                 principal debtor in respect of such liability in place of any
                 such Borrower;

         (d)     if it ceases to have the Minimum Rating as defined in clause
                 16.5, to lodge forthwith with the Security Agent cash cover as
                 security for its indemnity obligations in the same amount as
                 if it had been, on that date, a Substitute.

4.8      CALCULATION OF INTEREST IF BANK MAKES A GUARANTEE OR INDEMNITY PAYMENT

         Any payment made or to be made by a Bank pursuant to clause 4.7
         (Banks' Guarantee and Indemnity) and any unreimbursed amount on the
         part of the Issuing Bank shall (for the purpose of calculating
         interest thereon which is due from the relevant Borrower) be deemed to
         have been made available to that Borrower by way of a Revolving
         Advance on the date such payment is made or is to be made (or
         reimbursed) and accordingly is subject to the terms and conditions
         hereof and, after the earliest date on which a Revolving Advance could
         have
<PAGE>   36
                                     - 35 -



         been drawn down to fund such liability, such amount shall be treated
         as if it were an overdue sum with an initial term of one month but
         (for all other purposes) shall be immediately due and payable by the
         relevant Borrower.

4.9      DEFAULTING BANKS

         If a Bank (a "DEFAULTING BANK") fails to make payment on its due date
         of any amount (an "OVERDUE AMOUNT") due from it for the account of the
         Issuing Bank pursuant to clause 4.7 (Banks' Guarantee and Indemnity)
         then until the Issuing Bank (or the Agent on its behalf) has received
         payment of such overdue amount in full (and without prejudice to any
         other rights or remedies of the Issuing Bank in respect of such
         failure):

         (a)     the Issuing Bank shall be entitled to receive any remuneration
                 which such Defaulting  Bank would otherwise have been entitled
                 to receive in respect of the Revolving Credit Facility; and

         (b)     the overdue amount shall bear interest at the rate of one per
                 cent per annum over LIBOR plus the Additional Cost for the
                 time being from the due date until the date of payment and any
                 such interest which accrues shall be compounded monthly.

4.10     SUBROGATION OF BANKS MAKING GUARANTEE PAYMENTS

         (a)     Each Obligor agrees that if any Bank makes any payment under
                 clause 4.7 (Banks' Guarantee and Indemnity) it will
                 immediately be subrogated to any rights that the Issuing Bank
                 may then have against the relevant Borrower in respect of the
                 amount paid and such subrogation will be subject to the terms
                 set out in Schedule 7 (Terms of Borrowers' Indemnity).

         (b)     Each Obligor agrees to indemnify the Bank making such a
                 payment in respect of such payment and all costs and expenses
                 properly incurred by the Bank in recovering or attempting to
                 recover any amount pursuant to such rights of subrogation.

4.11     CURRENCY FLUCTUATIONS

         In addition and without prejudice to the Banks' other rights
         hereunder, the Facility Agent shall on every Quarter Date (and at any
         other time at which it is requested to do so by the Majority  Banks)
         calculate the aggregate of the Sterling Amounts of all Outstanding
         Contingent Liabilities under all Letters of Credit then outstanding.

4.12     CLAWBACK

         If the Facility Agent at any time issues a certificate addressed to
         the Primary Borrower that in its opinion the aggregate of the Sterling
         Amounts of Outstanding Contingent Liabilities under all Letters of
         Credit then outstanding is equal to or exceeds 105% of the aggregate
         amount of the Banks' Commitments under the Revolving Credit Facility
         less the amount of all outstanding Revolving Advances at that time,
         the Agent may give notice to the Primary Borrower requiring it within
         five Banking Days either to:

         (a)     make arrangements to repay Revolving Advances and/or reduce
                 the amount of the Letters of Credit outstanding so as to bring
                 the Sterling Amount of all such Outstanding Contingent
                 Liabilities to an amount equal to or below 100% of that
                 aggregate amount; or

         (b)     provide the Issuing Bank with cash cover in the currency in
                 which any Letter of Credit is denominated of such amount as
                 would cause the requirements of this clause 4.12 to be
                 satisfied.

4.13     CASH COVER

         Where cash cover is provided by an Obligor under clause 4.12
         (Clawback) or otherwise under this Agreement, the Issuing Bank or
         other recipient Bank undertakes to place the relevant cash deposit in
         an account with it (subject to such security arrangements as the
         Facility Agent may specify) bearing interest at a rate and on the
         standard terms (other than as to the security arrangements) applicable
         to corporate customers of such Bank making deposits of an equivalent
         size and for an equivalent duration (or on such other terms as such
         Bank and the relevant Obligor may agree).  Interest accruing on cash
         deposited as cash cover shall be for the account of and paid to such
         Obligor but shall not be paid to any Obligor during the continuance of
         an Event of Default.



5.       INTEREST AND INTEREST PERIODS

5.1      INTEREST ON THE ACQUISITION ADVANCES AND INTERIM ADVANCES

         The Primary Borrower shall pay interest on each Acquisition Advance
         and Interim Advance in respect of each Interest Period on the relevant
         Interest Payment Date (or, in the case of Interest Periods of more
         than six months, by instalments, every six months from the
         commencement of the relevant Interest Period and on the relevant
         Interest Payment Date) at the rate per annum determined by the
         Facility Agent to be the aggregate of (a) the Applicable Margin, (b)
         the Additional Cost and (c) LIBOR.

5.2      INTEREST PERIODS FOR THE ACQUISITION ADVANCES AND INTERIM ADVANCES

         (a)     The Primary Borrower may by notice received by the Facility
                 Agent not later than 11 a.m. on the second Banking Day before
                 the beginning of each Interest Period in respect of each
                 Acquisition Advance specify whether such Interest Period shall
                 have a duration of 1, 2, 3 or 6 months (or such other period
                 as the Facility Agent, acting on the instructions of the
                 Majority Banks, may agree).  All Interest Periods for the
                 Interim Facility shall have a duration of one month, save as
                 provided in (b) below.

         (b)     Every Interest Period in respect of each Acquisition Advance
                 and Interim Advance shall be of the duration specified by the
                 Primary Borrower pursuant to clause 5.2(a) but so that:

                 (i)      the initial Interest Period in respect of each such
                          Advance will commence on the relevant Drawdown Date
                          and each subsequent Interest Period in respect of
                          each such Advance shall commence on the date of the
                          expiry of the previous Interest Period, and until the
                          Syndication Date the provisions of clause 4.1(c)
                          shall apply to the selection of Interest Periods;

                 (ii)     if otherwise there would be more than 10 Acquisition
                          Advances or 10 Interim Advances outstanding with
                          different Interest Payment Dates, the Primary
                          Borrower shall select Interest Periods for such
                          Advances  ending on the same day as the then current
                          Interest Period for another such Advance and on the
                          last day of such Interest Period, such Advances shall
                          be consolidated into and shall thereafter constitute
                          a single Advance;

                 (iii)    if any Interest Period in respect of an Acquisition
                          Advance would otherwise overrun the Final Repayment
                          Date or the date the First Repayment is due, such
                          Interest Period shall end on such date;
<PAGE>   38
                                     - 37 -



                 (iv)     if any Interest Period in respect of an Interim
                          Advance would otherwise overrun the Available
                          Commitment Termination Date for the Interim Facility,
                          it shall end on such Available Commitment Termination
                          Date; and

                 (v)      if the Primary Borrower fails to select the duration
                          of an Interest Period in respect of an Advance in
                          accordance with the provisions of clause 5.2(a) and
                          this clause 5.2(b) such Interest Period shall have a
                          duration of 3 months or such other period as shall
                          comply with this clause 5.2(b) selected at the
                          Facility Agent's sole discretion.

5.3      INTEREST UNDER THE REVOLVING CREDIT FACILITY

         The relevant Revolving Credit Facility Borrower shall pay interest on
         each Revolving  Advance on its Maturity Date (or, in the case of a
         Revolving Advance having a Maturity Period of more than six months, by
         instalments, every six months from the relevant Drawdown Date and on
         the relevant Maturity Date) at the rate per annum determined by the
         Facility Agent to be the aggregate of (i) the Applicable Margin, (ii)
         the Additional Cost and (iii) LIBOR.

5.4      INTEREST ON UNPAID SUMS

         (a)     If any Borrower fails to pay any sum (including, without
                 limitation, any sum payable pursuant to this clause 5.4) on
                 its due date for payment under this Agreement such Borrower
                 shall pay interest on such sum from the due date up to the
                 date of actual payment (as well after as before judgment) at a
                 rate determined by the Facility Agent pursuant to this clause
                 5.4.

         (b)     The period beginning on the due date for payment and ending on
                 the date of actual payment shall be divided into successive
                 periods of not more than three months as selected by the
                 Facility Agent (after consultation with the Banks so far as
                 reasonably practicable in the circumstances) each of which
                 (other than the first, which shall commence on such due date)
                 shall commence on the last day of the preceding such period
                 but so that if the unpaid sum is an amount of principal which
                 shall have become due and payable prior to the next succeeding
                 Interest Payment Date relating thereto or, as the case may be,
                 prior to the relevant Maturity Date, then the first such
                 period selected by the Facility Agent shall end on such
                 Interest Payment Date or, as the case may be, such Maturity
                 Date.

         (c)     The rate of interest applicable to each period referred to in
                 clause 5.4(b) shall (subject to clause 5.6) be the aggregate
                 (as determined by the Facility Agent) of (i) one per cent per
                 annum, (ii) the Applicable Margin (iii) the Additional Cost
                 and (iv) LIBOR but so that if the unpaid sum is an amount of
                 principal (as referred to in clause 5.4(b)) interest shall be
                 payable on such unpaid sum during the first period determined
                 pursuant to clause 5.4(b) at a rate one per cent above the
                 rate applicable thereto immediately before it fell due.

         (d)     Interest under this clause 5.4 shall be due and payable on the
                 last day of each period determined by the Facility Agent
                 pursuant to this clause 5.4 or, if earlier, on the date on
                 which the sum in respect of which such interest is accruing
                 shall actually be paid or on such date or other dates which
                 the Facility Agent may specify by written notice to the
                 Primary Borrower (but not more frequently than once a month).
                 Any interest payable under this clause 5.4 which is not paid
                 when due shall be deemed  an unpaid sum and shall itself bear
                 interest accordingly.

5.5      NOTIFICATION OF INTEREST PERIODS AND INTEREST RATE

         The Facility Agent shall notify the Primary Borrower (who shall notify
         any other relevant Borrower) and the Banks promptly of the duration of
         each Interest Period, Maturity Period or other period for the
         calculation of interest (or, as the case may be, default interest) and
         of each rate of interest determined by it under this clause 5.

5.6      ALTERNATIVE INTEREST RATES

         If:

         (a)     in attempting to calculate LIBOR under paragraph (b) of the
                 definition of LIBOR for a specified period the Facility Agent
                 determines at 11.00 a.m. (London time) on the Quotation Date
                 that it is unable to obtain quotations for LIBOR from any of
                 the Reference Banks in respect of the relevant Advance or
                 unpaid sum for the specified period; or

         (b)     before its close of business on such day, the Facility Agent
                 has been notified in writing by a Bank or group of Banks to
                 which 35% or more of the relevant Advance or unpaid sum is
                 (or, if the relevant Advance were made, would then be) owed
                 that LIBOR calculated in accordance with its definition in
                 this Agreement does not accurately reflect the cost to them of
                 funding their participation; or

         (c)     the Facility Agent, acting reasonably, determines that, by
                 reason of circumstances affecting the London inter-bank
                 market, adequate and fair means do not or will not exist for
                 determining the rate of interest applicable to the specified
                 period,

         then:

                 (i)      the Facility Agent shall promptly notify in writing
                          the Primary Borrower and the Banks of such event or
                          circumstance;

                 (ii)     the Facility Agent (on behalf of and after
                          consultation with the Banks) shall, within three
                          Banking Days of such notice, negotiate with the
                          Primary Borrower with a view to agreeing a substitute
                          basis on which the relevant part of the Facility may
                          be maintained;

                 (iii)    any substitute basis agreed in writing by the
                          Facility Agent (on behalf of and with the consent of
                          all the Banks) and the Primary Borrower within 30
                          days of such notice shall take effect in accordance
                          with its terms and interest shall be calculated as if
                          the substitute basis had come into effect from the
                          beginning of the relevant specific period;

                 (iv)     in default of agreement within 30 days, each Bank's
                          participation in the Advance or unpaid sum (if any)
                          shall during that specific period bear interest at
                          the annual rate equal to the cost to that Bank (as
                          certified by it to the Primary Borrower within ten
                          days of the end of that 30 day period and expressed
                          as a percentage rate per annum) of funding its
                          participation during that specific period by whatever
                          means that Bank determines to be most appropriate
                          plus the Applicable Margin and the Additional Cost
                          and if clause 5.4 (Interest on unpaid sums) applies,
                          a further one per cent.

                 relevant Bank to all the relevant Facilities shall be reduced
                 to zero and the undrawn amount of the Total Commitments in
                 respect of all the Facilities shall be reduced accordingly.

         (b)     Instead of or, in addition to, its rights under clause 6.5(a)

                 Bank to transfer pursuant to clause 16.5 at par all of its
                 Commitments and Contributions to a Qualifying Bank nominated
                 by the Borrower provided that the relevant Qualifying Bank
                 agrees (in its absolute discretion) to accept the transfer to
                 it and, in the case of clause 14.1, that Bank is lawfully able
                 to do so and the transfer is to take effect prior to the

                 prepayment pursuant to clause 14.1 such notice as is required
                 under clause 14.1) specifying the proposed date of the
                 prepayment and the amount to be prepaid.  Every such notice
                 shall be effective only on actual receipt by the Facility
                 Agent, shall be irrevocable and shall oblige the relevant
                 Borrower to make the relevant prepayment on the date
                 specified.

                 which is repaid or prepaid may be reborrowed.

                 the following order:

                 (i)      against outstanding Interim Advances;

                 (ii)     against outstanding Acquisition Advances, in inverse

                                  Repayment; and

                          (bb)    voluntary prepayments shall be applied first
                                  against the First Repayment and thereafter
                                  against the Final Repayment;

                 (iii)    in repayment of outstanding Revolving Advances and in

         (d)     All prepayments shall be made together with (to the extent
                 these relate to the amounts prepaid) (i) accrued interest to
                 the date of prepayment; (ii) any additional amount payable
                 under clauses 8.5 or 14.2; and (iii) all other sums payable by
                 the Borrower to the relevant Banks under this Agreement
                 including, without limitation, any accrued commitment
                 commission payable under clause 7.2, any Letter of Credit
                 commission and fees under clause 7.3, expenses under clause

                 expressly provided herein.

6.7      CANCELLATION OF THE FACILITIES

         The Primary Borrower may at any time prior to the Available Commitment
         Termination Date in respect of the relevant Facility by notice to the
         Facility Agent (effective only on actual receipt) cancel with effect
         from a date not less than 10 Banking Days after the receipt by the
         Facility Agent of such notice the whole or any part (if in part, being
         L.10,000,000 or any larger sum which is an integral multiple of
         L.5,000,000) of the Available Facility Amount of the relevant
         Facility, in each case which is not the subject of a Drawdown Notice
         at such time.  Such notice shall specify the Facility to which it
         refers, the date upon which such cancellation is to be made and the
         amount of such cancellation.  Any such notice of cancellation, once
         given, shall be irrevocable and upon such cancellation taking effect
         the Commitments of the Banks in respect of the relevant Facility shall
         be reduced accordingly (pro-rata their respective Commitments in
         respect of the relevant Facility).

6.8      TERMINATION

         The Commitment of each Bank shall be automatically cancelled and
         reduced to zero at the close of business in London on the relevant

         Cancellation Date.

         (b)     on the date of this Agreement and on each anniversary thereof
                 until the end of the Finance Period, for the account of the
                 Facility Agent, an agency fee and for the account of the
                 Security Agent, a security agency fee, in each case of an
                 amount agreed between the Primary Borrower and the Facility
                 Agent in a letter dated on or about the date of this
                 Agreement.

         7.2     COMMITMENT FEES

         The Primary Borrower shall pay to the Facility Agent, whether or not
         any part of the Commitments is ever advanced, from the date of this

         and on the Available Commitment Termination Date in respect of each
         Facility (or the Cancellation Date if earlier), for the account of

         relevant Facility), commitment commission computed in arrears at the
         Applicable Fees Rate on the daily amount by which the Total
<PAGE>   43
                                     - 42 -



         Commitments in respect of the relevant Facility exceeds the aggregate
         of the Contributions in respect of the relevant Facility.  Accrued
         commitment commission will also be payable on the amount of any
         Commitment when cancelled on the date of its cancellation.

7.3      LETTER OF CREDIT FEES

         (a)     Each relevant Borrower shall (on the dates set out in clause
                 7.3(c)) pay commission in Sterling to the Facility Agent for
                 the account of the Banks (in their respective Proportions) on
                 the Issue of any Letter of Credit requested by such Borrower
                 in Sterling at a percentage rate per annum equal to the
                 Applicable Margin on the Sterling Amount of the Outstanding
                 Contingent Liabilities under such Letter of Credit calculated
                 in each case on the date of Issue and recalculated on each

                 liability (actual or contingent) in respect thereof, and on
                 the basis of a 365 day year.  If the relevant Borrower has
                 provided cash cover for any Letter of Credit, the percentage
                 rate per annum payable on cash covered amounts shall instead
                 be 0.25%.

         (b)     Each relevant Borrower shall pay a fronting fee to the
                 Facility Agent for the account of the Issuing Bank on the
                 Issue of any Letter of Credit at a rate of 0.2% per annum on
                 the Sterling Amount of the face amount of the relevant Letter
                 of Credit payable in advance on the date of Issue and on each
                 Quarter Date thereafter.

         (c)     The commission and fronting fee payable under clauses 7.3(a)
                 and 7.3(b) in respect of each Letter of Credit shall be paid
                 in advance on the relevant Issue Date and on each Quarter Date
                 in each year during the continuance of such Letter of Credit
                 (or if such day is not a Banking Day, on the preceding Banking
                 Day) commencing on the first Quarter Date falling on or after
                 the Issue of the relevant Letter of Credit.  If a Letter of
                 Credit is terminated leaving no Outstanding Contingent
                 Liabilities before a Quarter Date, any commission paid in
                 advance for the period from the date of cancellation until the
                 next Quarter Date shall be repaid to the Borrower which made
                 the advance commission payment by set-off against any amounts
                 then due from the Borrower to any Finance Party or, if no such
                 amounts are due, by payment in cash.

         (d)     For the avoidance of doubt, the Issuing Bank's Proportion of
                 the commission at the rate and calculated in the manner
                 specified in clause 7.3(a) shall be payable to the Issuing
                 Bank in respect of its residual liability in its capacity as a
                 Bank, notwithstanding that it does not purport to guarantee
                 itself in its capacity as Issuing Bank.

         (e)     The Borrowers shall pay interest on the amount demanded and
                 outstanding under the indemnity given by them in respect of
                 Letters of Credit in accordance with clause 4.8 (Calculation
                 of Interest if Bank makes a Guarantee or Indemnity Payment) in
                 addition to the commission and other fees payable under this
                 Agreement in respect of the Revolving Credit Facility.

         7.4     EXPENSES

         The Primary Borrower shall reimburse the Arrangers, the Banks, the
         Security Agent and the Facility Agent from time to time within three
         Banking Days of demand:

         (a)     all reasonable costs and expenses (including without
                 limitation legal, printing and out-of-pocket expenses)
                 together with any VAT thereon incurred by the Facility Agent
                 and the Arrangers in connection with the negotiation,
                 preparation and execution of the Finance Documents and the
                 completion and syndication of the transactions therein
                 contemplated, and the negotiation, preparation

                 and execution of any amendment or extension of, or the
                 granting of any waiver or consent under, any of the Finance
                 Documents; and

         (b)     without prejudice to the generality of (c) below, all expenses
                 and costs (including without limitation the fees and expenses
                 of lawyers, accountants, surveyors, valuers, environmental
                 consultants and other professional advisers and out-of-pocket
                 expenses) incurred by the Facility Agent in connection with
                 the obtaining of reports and/or advice and/or the undertaking
                 of investigations by or on behalf of the Facility Agent into
                 or concerning the Primary Borrower or the Group following the
                 occurrence of a Default and whilst it is continuing (or where
                 the Majority Banks' reasonable opinion is that a Default may
                 have occurred) and the Primary Borrower undertakes to give,
                 and to procure that its Subsidiaries give, all such reasonable
                 assistance (including, without limitation, access to its
                 and/or their properties and financial and other records) at
                 all times as the Facility Agent shall reasonably require for
                 the purpose of enabling such reports or advice to be prepared
                 or such investigations to be undertaken; and

         (c)     after a Default has occurred, all costs and expenses
                 (including without limitation legal and out-of- pocket
                 expenses) incurred by any of the Finance Parties in
                 contemplation of, or otherwise in connection with, the
                 enforcement or attempted enforcement of, or preservation or
                 attempted preservation of any rights under, any of the Finance
                 Documents, or otherwise in respect of the recovery, or
                 attempted recovery, of moneys owing under the same, together
                 with interest at the rate referred to in clause 5.4 from the
                 date on which such expenses were incurred to the date of
                 payment (as well after as before judgment).

7.5      VALUE ADDED TAX

         All fees, costs and expenses payable pursuant to this clause 7 shall
         be paid together with an amount equal to any VAT thereon payable by
         any of the Finance Parties in respect of such fees and expenses.

7.6      STAMP AND OTHER DUTIES

         The Primary Borrower shall pay all stamp, documentary, registration,
         notarisation or other duties or Taxes (including any duties or Taxes
         payable by, or assessed on, the Finance Parties) imposed on or in
         connection with the negotiation, preparation, and execution of any of
         the Finance Documents and the syndication of the Facilities and shall
         indemnify the Finance Parties against any liability arising by reason
         of any delay or omission by the Primary Borrower to pay such duties or
         Taxes.


8.       PAYMENTS AND TAXES; ACCOUNTS AND CALCULATIONS

8.1      NO SET-OFF OR COUNTERCLAIM; DISTRIBUTION TO THE BANKS

         All payments to be made by any Borrower under this Agreement shall be
         made in full, without any set-off or counterclaim whatsoever and,
         subject as provided in clause 8.5, free and clear of any deductions or
         withholdings, in Sterling (except for costs, charges or expenses which
         shall be payable in the currency in which they are incurred) on the
         due date to the account of the Facility Agent at such bank as the
         Facility Agent may from time to time specify for this purpose.  Save
         where this Agreement provides for a payment to be made for the account
         of a particular Finance Party or Finance Parties, in which case the
         Facility Agent shall distribute the relevant payment to the relevant
         Finance Party or Finance Parties concerned, payments to be made by any
         Borrower under this Agreement shall be for the account of all the
         Banks and the Facility Agent shall forthwith distribute such payments
         in like funds as are received by the Facility Agent to the Banks
         rateably for the account of such Banks' respective Facility Offices in
         accordance with their Commitments or Contributions, as the case may
         be.

8.2      PAYMENTS BY THE BANKS

         All sums to be advanced by the Banks to any Borrower under this
         Agreement shall be remitted in Sterling in immediately available funds
         not later than 11 a.m. on the relevant Drawdown Date or, as the case
         may be, the first day of the relevant Interest Period to the account
         of the Facility Agent at such bank as the Facility Agent may have
         notified to the Banks and shall be paid by the Facility Agent on such
         date to the account of the relevant Borrower in England specified in
         the relevant Drawdown Notice.

8.3      NON-BANKING DAYS

         When any payment under this Agreement would otherwise be due on a day
         which is not a Banking Day, the due date for payment shall be
         postponed to the next following Banking Day unless such Banking Day
         falls in the next calendar month, in which case payment shall be made
         on the immediately preceding Banking Day.

8.4      FACILITY AGENT MAY ASSUME RECEIPT

         Where any sum is to be paid under this Agreement to the Facility Agent
         for the account of another person, the Facility Agent may assume that
         the payment will be made when due and may (but shall not be obliged
         to) make such sum available to the person so entitled.  If it proves
         to be the case that such payment was not made to the Facility Agent,
         then the person to whom such sum was so made available shall on
         request refund such sum to the Facility Agent together with interest
         thereon sufficient to compensate the Facility Agent for the cost of
         making available such sum up to (and/or, as the case may be, the cost
         to the relevant other person of not receiving such sum until) the date
         of such repayment and the person by whom such sum was payable shall
         indemnify the Facility Agent (or the relevant other person) for any
         and all loss or expense which the Facility Agent (or the relevant
         other person) may sustain or incur as a consequence of such sum not
         having been paid on its due date together with any interest, expenses
         and penalties payable or incurred in connection therewith.

8.5      GROSSING-UP FOR TAXES

         If at any time any Borrower is required to make any deduction or
         withholding in respect of Taxes from any payment due under any Finance
         Document for the account of any Finance Party (or if the Facility
         Agent, or as the case may be, the Security Agent is required to make
         any such deduction or withholding from a payment to a Finance Party),
         the sum due from the relevant Borrower in respect of such payment
         shall, subject to clause 8.6, be increased to the extent necessary to
         ensure that, after the making of such deduction or withholding (and
         any further deduction and withholding which may be levied on the
         additional amounts paid by reason of this clause), each Finance Party
         receives on the due date for such payment (and retains, free from any
         liability in respect of such deduction or withholding) a net sum equal
         to the sum which it would have received and so retained had no such
         deduction or withholding been made or required to be made and (without
         prejudice to the foregoing provisions of this clause 8.5) each
         Borrower shall indemnify each Finance Party on demand by the Facility
         Agent against any losses or costs incurred by any of them together
         with any interest, expenses and penalties payable or incurred in
         connection therewith by reason of any failure of such Borrower to make
         any such deduction or withholding.

         Each Borrower shall promptly deliver to the Facility Agent any
         receipts, certificates or other proof evidencing the amounts (if any)
         paid or payable in respect of any such deduction or withholding.

8.6     QUALIFYING BANK

        (a)      If:

                 (i)      any Bank is not or ceases to be a Qualifying Bank; and

                 (ii)     as a result an Obligor is required to deduct or
                          withhold United Kingdom income tax in respect of
                          payments of interest to be made by such Obligor to
                          that Bank under any Finance Document or would
                          otherwise have been required to make an indemnity
                          payment or a greater indemnity payment under clause
                          8.5 or 14.2,

                 then such Obligor shall (as the case may be) not be liable to
                 pay under clause 8.5 in respect of any such payment of
                 interest any amount in excess of the amount it would have been
                 obliged to pay if such Bank were a Qualifying Bank, nor shall
                 it be liable to make an indemnity payment or a greater
                 indemnity payment under clause 8.5 or, as the case may be,
                 Clause 14.2 than would have been required if the aforesaid
                 Bank had been or had not ceased to be a Qualifying Bank
                 Provided that this Clause 8.6 shall not apply, and such
                 Obligor shall be obliged to comply with its obligations under
                 clause 8.5, or as the case may be 14.2, if on or after the
                 date hereof:

                 (aa)     there shall have been any change in, or in the
                          official interpretation or application of, any
                          relevant law or the practice of the United Kingdom
                          Inland Revenue (or, in the case of a Treaty Lender,
                          any Government Entity in the country in which it is
                          resident for the purpose of the relevant double
                          taxation treaty) and as a result thereof the Bank is
                          not or ceases to be a Qualifying Bank, or

                 (bb)     the Bank referred to in clause 8.6(a) has transferred
                          its Facility Office in respect of any Facility
                          outside the United Kingdom or has become a Bank
                          hereunder with a Facility Office outside the United
                          Kingdom in respect of any Facility, in each case,
                          with the consent of the Primary Borrower if and
                          insofar as required under this Agreement.

         (b)     A person intending to make a claim pursuant to clause 8.5
                 shall, promptly after such person becomes aware of the
                 circumstances giving rise to such claim and the amount of such
                 claim, deliver to the Primary Borrower through the Facility
                 Agent a certificate to that effect specifying the amount of
                 such claim and setting out in reasonable detail the basis of
                 such claim, provided that nothing shall require such person to
                 disclose any confidential information relating to the
                 organisation of its affairs.

         (c)     If at any time after the date of this Agreement any Bank is
                 aware that it is not or will cease to be a Qualifying Bank
                 (for whatever reason), it shall promptly notify the Primary
                 Borrower.

         (d)     A Treaty Lender will submit such claim to the appropriate
                 authorities (together with such forms, papers, other documents
                 and/or evidence as necessary) as may be required for the
                 Obligors to make payment of interest to such Treaty Lender on
                 its Advances free of withholding or deduction on account of
                 United Kingdom Tax.  No Obligor will be liable to pay any
                 additional amount under clause 8.5 in respect of the
                 withholding or deduction on account of United Kingdom income
                 tax from any such interest unless such claim has been
                 submitted to those authorities promptly after that Treaty
                 Leader became a party to this Agreement as a Treaty Lender or
                 the proviso to clause 8.6(a) applies.

8.7      CLAW-BACK OF TAX BENEFIT

         If following any such deduction or withholding as is referred to in
         clause 8.5 any Finance Party determines in its sole discretion that it
         has received or been granted a credit against or remission for any
         Taxes payable by it, such Finance Party shall, subject to the relevant
         Borrower having made any increased payment in accordance with clause
         8.5 and subject to there not being any Default which is continuing,
         and to the extent that such Finance Party can do so without
         prejudicing the retention of the amount of such credit or remission
         and without
<PAGE>   47
                                     - 46 -



         prejudice to the right of such Finance Party to obtain any other
         relief or allowance which may be available to it, reimburse the
         relevant Borrower with such amount as such Finance Party shall in its
         absolute discretion certify to be the proportion of such credit or
         remission as will leave such Finance Party (after such reimbursement)
         in no worse position than it would have been in had there been no such
         deduction or withholding from the payment by the relevant  Borrower as
         aforesaid.  Such reimbursement shall be made forthwith upon such
         Finance Party certifying that the amount of such credit or remission
         has been received by it, provided that the Finance Party shall be the
         sole judge of the amount of any such benefit and of the date on which
         it was received.  Nothing contained in this Agreement shall interfere
         with the right of any Finance Party to arrange its tax affairs in
         whatever manner it thinks fit nor oblige any Finance Party to disclose
         any information regarding its tax affairs and computations. Without
         prejudice to the generality of the foregoing, no Borrower shall, by
         virtue of this clause 8.7, be entitled to enquire about any Finance
         Party's tax affairs or computations.  The Finance Parties are under no
         obligation to investigate whether any tax credit is available or to
         claim any tax credit.  Any amount paid by any Finance Party to a
         Borrower under this clause shall be conclusive evidence of the amount
         payable and will be accepted by the Borrower in full and final
         settlement of its claim.

8.8      BANK ACCOUNTS

         Each Bank shall maintain, in accordance with its usual practices, an
         account or accounts evidencing the amounts from time to time lent by,
         owing to and paid to it under this Agreement.  The Facility Agent
         shall maintain a control account showing the utilisation of the
         Facilities and other sums owing by each Borrower under this Agreement
         and all payments in respect thereof made by each Borrower from time to
         time.  In any legal action arising out of or in connection with the
         Finance Documents the entries made in the accounts maintained pursuant
         to this clause 8.8 shall, in the absence of manifest error, be
         conclusive as to the amount from time to time owing by each Borrower
         under this Agreement.

8.9      PARTIAL PAYMENTS

         If:

         (a)     on any date on which a payment is due to be made by any
                 Borrower under this Agreement, the amount received by the
                 Facility Agent from such Borrower falls short of the total
                 amount of the payment due to be made by such Borrower on such
                 date; or

         (b)     on any date on which the Facility Agent receives any payment
                 from the Security Agent or otherwise receives any amount
                 representing proceeds of realisations or other recoveries
                 under any of the Security Documents, the amount of such
                 payment or other receipt falls short of the total amount owing
                 to the Finance Parties under this Agreement on such date 
         then (in any such case), without prejudice to any rights or remedies
         available to the Finance Parties under any of the Finance Documents,
         the Facility Agent shall apply the amount actually received by it in or
         towards discharge of the obligations of such Borrower under this
         Agreement in the following order, notwithstanding any appropriation
         made, or purported to be made, by such Borrower:

                 (i)      first, in or towards payment, on a pro-rata basis, of
                          any unpaid costs and expenses of the Facility Agent,
                          Security Agent or the Arrangers under this Agreement;

                 (ii)     secondly, in or towards payment to the Banks, on a
                          pro-rata basis, of any amount owing to the Banks
                          under clause 20.2;
<PAGE>   48
                                     - 47 -




                 (iii)    thirdly, in or towards payment to the Arrangers, on a
                          pro-rata basis, of any portion of the fees payable
                          under clause 7.1(a) which remains unpaid;

                 (iv)     fourthly, in or towards payment to the Facility Agent
                          and the Security Agent, on a pro-rata basis, of any
                          portion of the fees payable under clause 7.1(b) which
                          remains unpaid;

                 (v)      fifthly, in or towards payment to the Banks, on a
                          pro-rata basis, of any accrued commitment commission
                          payable under clause 7.2 which shall have become due
                          but remains unpaid;

                 (vi)     sixthly, in or towards payment to the Banks, on a
                          pro-rata basis, of any accrued interest, Letter of
                          Credit commission and (in the case of the Issuing
                          Bank) Letter of Credit fronting fees or commission
                          which shall have become due but remain unpaid, but so
                          that any amount payable by virtue of clause 8.5 shall
                          be excluded;

                 (vii)    seventhly, in or towards payment to the Banks, on a
                          pro-rata basis, of any principal which shall have
                          become due but remains unpaid;

                 (viii)   eighthly, in or towards payment to any such Banks, on
                          a pro-rata basis, of any amount payable to any Banks
                          by virtue of clause 8.5 which remains unpaid; and

                 (ix)     ninthly, in or towards payment of any other sum which
                          shall have become due but remains unpaid (and, if
                          more than one such sum so remains unpaid, on a
                          pro-rata basis).

         Each reference in clause 8.9(i) to (ix) (inclusive) to a category of
         unpaid sums shall include interest thereon payable in accordance with
         this Agreement (including, without limitation, default interest under
         clause 5.4).  Accordingly, clause 8.9(vi) shall be construed as
         referring to interest on principal and accrued interest thereon which
         remain unpaid to the extent due.

         The order of application set out in this clause 8.9(v) to 8.9(ix)
         shall be varied by the Facility Agent if the Majority Banks so direct,
         without any reference to, or consent or approval from, the Borrowers.

8.10     CALCULATIONS

         All interest and other payments of an annual nature under this
         Agreement or any of the Security Documents shall accrue from day to
         day and be calculated on the basis of the actual number of days
         elapsed, and in the case of Sterling a 365 day year and in the case of
         other currencies a 360 day year.   In calculating the actual number of
         days elapsed in a period which is one of a series of consecutive
         periods with no interval between them or a period on the last day of
         which any payment falls to be made in respect of such period, the
         first day of such period shall be included but the last day excluded.

         Where the Applicable Margin or Additional Cost changes during any
         period, interest and commitment fees shall be calculated on the rate
         prevailing from day to day.

8.11     CERTIFICATES CONCLUSIVE

         Any certificate of, or determination by, a Finance Party as to any
         rate of interest or any other amount payable under this Agreement or
         any of the Security Documents shall, in the absence of manifest error,
         be conclusive and binding evidence of such rate or amount on each
         Borrower and (in the case of a certificate of or determination by the
         Facility Agent) on the Banks.

8.12     EFFECT OF MONETARY UNION

         If the country of any national currency in which any amount is
         expressed to be payable under this Agreement participates in economic
         and monetary union in accordance with Article 109J of the Treaty on
         European Union, then:

         (a)     any amount expressed to be payable under this Agreement in
                 that national currency shall (until the end of the
                 transitional period) be made in that national currency or in
                 Euros as the Facility Agent may, by not less than two Banking
                 Days' notice to the Primary Borrower and the Banks to that
                 effect, require;

         (b)     any amount so required under clause 8.12(a) to be paid in
                 Euros shall be converted from that national currency at the
                 rate stipulated pursuant to Article 109L(4) of the Treaty on
                 European Union and payment of the amount in Euro derived from
                 such conversion shall discharge the obligation of the relevant
                 party to pay such national currency amount; and

         (c)     after consultation with the Primary Borrower and the Banks and
                 notwithstanding clause 22, the Facility Agent shall be
                 entitled to make from time to time such amendments to this
                 Agreement as it may determine to be necessary to take account
                 of monetary union and any consequent changes in market
                 practices (whether as to the settlement or rounding of
                 obligations, the calculation of interest or otherwise
                 howsoever).

         Any amendment so made to this Agreement by the Facility Agent shall be
         promptly notified to the other Finance Parties and the Primary
         Borrower by the Facility Agent and shall be binding on all the other
         Finance Parties and any Borrower and any other party to this
         Agreement.

                 ancillary thereto, copies of which have been provided to the
                 Arrangers) prior to the date of this Agreement neither the

                 trading or incurred any material liabilities of any nature

                 might reasonably be expected to have a Material Adverse
                 Effect, or which might reasonably be expected to be material
                 to a bidder in the context of whether to make an offer or
                 whether the offer is correctly priced;

         (d)     Agreed Projections: the Agreed Projections delivered to the
                 Arrangers prior to the date of this Agreement in the agreed
                 form were arrived at after careful consideration, were fair
                 and were based on assumptions which were reasonable having

                 Primary Borrower, Finco 2 and Bidco;

                 (i)      no litigation, alternative dispute resolution,
                          arbitration or administration proceeding is taking

                          of the Primary Borrower, Finco 2 or Bidco, threatened
                          against the Primary Borrower, Finco 2 or Bidco; and

                 (ii)     so far as it is aware, no litigation, alternative
                          dispute resolution, arbitration or administration
                          proceeding is taking place, pending or threatened
                          against any other member of the Group which is
                          reasonably likely (in the reasonable opinion of the
                          Majority Banks) in either case to have a Material
                          Adverse Effect.

9.3      REPRESENTATIONS ON AND FROM THE TAKEOVER OPERATIVE DATE

         Each Obligor party hereto represents and warrants to each Finance

         (a)     Compliance with Environmental Laws:  each member of the Group:

                 (i)      as at the Takeover Operative Date complies; and

                 (ii)     has (to the extent that non-compliance would be
                          reasonably likely to give rise to a material
                          liability as at the Takeover Operative Date) at all
                          times complied,

                 in all material respects with all Environmental Laws, where
                 non-compliance, in each case, would be reasonably likely to
                 have a Material Adverse Effect;

         (b)     No Environmental Claims:

                 (i)      no Environmental Claim is pending or has been made or
                          threatened against any member of the Group or any of
                          their respective officers in their capacity as such;
                          and

                 (ii)     no member of the Group is aware of any circumstances
                          or situation which would be reasonably likely to
                          result in it having any liability in relation to
                          Environmental Matters,

                 which, in either case, would be reasonably likely to have a
                 Material Adverse Effect;

                                  conduct of its business as a generator of

                          the contravention or consequence of which is
                          reasonably likely to have a Material Adverse Effect;

         (d)     The Licences:

                 (i)      each Licence is in full force and effect and neither
                          the Director General nor the Director General of Gas

                 accounting principles from the Appropriate Accounting
                 Principles unless:

                 (i)      the revised policy and practice adopted from time to
                          time is in accordance with generally accepted
                          accounting practice in the United Kingdom, and

                 (ii)     prior to any revised policy and practice being
                          adopted the Primary Borrower has notified the
                          Facility Agent thereof and, if required by the
                          Facility Agent, will negotiate in good faith with the
                          Facility Agent in order that the Financial Covenants
                          may be amended as required by the Facility Agent in
                          order for it to be able to make the same judgments as

                 commencement of such negotiations each of the Primary Borrower
                 and Finco 2 agrees that it will procure that the Auditors
                 provide financial statements reflecting the Appropriate
                 Accounting Policies, and any reference in this Agreement to
                 financial statements under this Agreement shall be construed
                 as a reference to such financial statements as adjusted to
                 reflect the Appropriate Accounting Policies;

         (d)     For the purposes of calculating Net Interests Costs, any
                 incremental impact of interest rate hedging transactions or
                 refinancings entered into by the Primary Borrower from time to
                 time shall be treated as varying the Net Interest Costs
                 payable by Finco 2, whether or not they actually do so;

         (e)     Each of the Primary Borrower and Finco 2 undertakes with each
                 of the Finance Parties that it will not vary or waive the
                 terms of the Investment Agreement, and undertakes to procure

                          closed within the period required by clause 10.4(f)
                          below) or agree or decide not to invoke, in whole or
                          in part, in any material respect, any of the other
                          material conditions of the Offer (and the Primary
                          Borrower, Finco 2 and Bidco acknowledge that the
                          total Indebtedness of the Target Group requiring to
                          be refinanced, and the amount of any contingent
                          liabilities of the Target Group which would or might
                          crystallise upon the Offer becoming unconditional,
                          are material), provided that the Primary Borrower,
                          Finco 2 and Bidco shall not be in breach of this
                          clause (vi) if they fail to invoke a condition of the
                          Offer because the Takeover Panel has directed that
                          they may not do so.

         (b)     Each of the Primary Borrower, Finco 2 and Bidco acknowledges
                 and confirms to the Finance Parties that if any event or
                 circumstance occurs which under the conditions of the Offer
                 may entitle Bidco to lapse the Offer, Bidco will promptly
                 notify the Facility Agent and if in the reasonable opinion of
                 the Majority Banks such event or circumstance would have a
                 material and adverse affect on the ability of the Borrowers to
                 comply with their material obligations under this Agreement
                 (or the adequacy of the facilities available for refinancing
                 indebtedness or other liabilities of the Target Group) and the
                 Facility Agent acting on the instructions of the Majority
                 Banks so requests, Bidco will promptly seek the consent of the
                 Takeover Panel to lapse the Offer.  If the Takeover Panel
                 consents to Bidco's lapsing the Offer in the light of such
                 event or circumstance, Bidco shall then lapse the Offer
                 promptly.

         (c)     Each of the Primary Borrower, Finco 2 and Bidco shall keep the
                 Arrangers informed and consult with them as to:

                 (i)      the terms of any undertaking or assurance proposed to
                          be given by it, any of its Affiliates or any member
                          of the Target Group to the Director General, the
                          Director General of Gas Supply or the Secretary of
                          State for Trade and Industry in connection with the
                          Offer;

                 (ii)     the terms of any modification to any of the Licences
                          proposed in connection with the Offer;

                 (iii)    any terms proposed in connection with any
                          authorisation or determination necessary or
                          appropriate in connection with the Offer;

                 If the Majority Banks (acting reasonably) state that in their
                 opinion such proposed undertakings(s), assurance(s),
                 modification(s) and/or term(s), or compliance therewith, would
                 materially and adversely affect the ability of the Group to
                 comply with its material obligations under the Finance
                 Documents, Bidco shall promptly request the Takeover Panel to
                 confirm (and shall use its reasonable endeavours to ensure
                 that the Takeover Panel does confirm) that the Takeover Panel
                 will not object to the lapsing

                                     - 58 -



                 of the Offer as a result of the non-satisfaction of whichever
                 of the conditions in Appendix 1 to the Press Release is
                 relevant, provided that Bidco will not be obliged to lapse the
                 Offer as a result of any proposed modifications of any Licence
                 or any proposed undertakings or assurances from the Primary
                 Borrower, Finco 2, Bidco or any member of the Target Group to
                 be given to the Director General to the extent that such
                 modifications, undertakings or assurances (as the case may be)
                 are no more onerous than those set out and required by the
                 Director General from Pacificorp and/or the Target Group in
                 accordance with the terms of the Monopolies and Mergers
                 Commission Report dated 19 December 1997 into the original
                 Pacificorp offer for the Target.  If the Takeover Panel gives
                 a confirmation substantially in those terms, Bidco shall at
                 the earliest opportunity declare the Offer lapsed by reason of
                 the non- fulfilment of such condition(s).

         (d)     Each of the Primary Borrower, Finco 2 and Bidco acknowledges
                 and confirms to the Finance Parties that the Offer, or an
                 accompanying circular to shareholders of the Target, should
                 also contain a super class one resolution to be passed by the
                 shareholders of the Target, seeking approval of the completion
                 of the Coalco Disposal Agreement with effect on and from the
                 Unconditional Date.  Where the context permits, all references
                 in this Agreement (and in the Offer) to the Offer being
                 accepted and/or becoming unconditional shall be construed to
                 include such approval being granted.

         (e)     Each of the Primary Borrower, Finco 2 and Bidco undertakes to
                 the Finance Parties that within 15 days of the date on which
                 acceptances of the Offer are received from holders of not less
                 than 90% of the Target Shares to which the Offer relates,
                 Bidco shall procure that a director of Bidco issues a
                 statutory declaration pursuant to section 429(4) of the
                 Companies Act 1985, gives notice to all remaining holders of
                 the Target Shares that it intends to acquire their shares
                 pursuant to section 429 of the Companies Act 1985, and Bidco
                 shall subsequently purchase all such shares.

         (f)     Each of the Primary Borrower, Finco 2 and Bidco undertakes to
                 the Finance Parties that Bidco shall in any event give notice
                 to close the Offer no later than 120 days after the date of
                 this Agreement, unless the Arrangers agree in their absolute
                 discretion to extend such period.

10.5     DELISTING

         Each of the Primary Borrower, Finco 2 and Bidco undertakes to the
         Finance Parties to procure that, as soon as legally and practically
         possible after the Unconditional Date, the American Depositary Shares
         represented by the American Depositary Receipts tendered to Bidco
         shall be converted into ordinary shares of the Target or otherwise
         held in form satisfactory to the Security Agent, the Target shall be
         removed from the Official List of the London Stock Exchange Limited
         and reregistered as a private company and its American Depositary
         Shares shall be delisted from the New York Stock Exchange.

10.6     FINANCIAL ASSISTANCE AND GUARANTEES

         Each Obligor party hereto undertakes with each of the Finance Parties
         that it will take all steps available to it to procure that any
         company in the Target Group selected and notified to the Principal
         Borrower by the Facility Agent shall give such guarantees to the
         Security Agent as may be requested by the Facility Agent, in respect
         of the Indebtedness of the Borrowers to the Banks, save that no such
         guarantee may be requested (or, if requested, may be refused) where:

         (a)     the giving of such a guarantee would be unlawful and it is not
                 legally possible for the proposed giver of such guarantee to
                 take steps to render the giving of such guarantee lawful; or
<PAGE>   60
                                     - 59 -




         (b)     the giving of any such guarantee would reasonably be expected
                 to breach a condition of any of the Licences or the Pooling
                 and Settlement Agreement or the Gas Framework Agreement and,
                 as a consequence, entitle the Secretary of State, the Director
                 General or the Director General of Gas Supply to revoke or
                 withdraw such Licence, or amend such Licence in any respect
                 which would reasonably be expected to have a Material Adverse
                 Effect; or

         (c)     the giving of such a guarantee would:

                 (i)      cause any of the Existing Public Debt to be repayable
                          at the option of the holder thereof or cause the
                          coupon thereunder to increase materially; and/or

                 (ii)     cause Indebtedness under the Existing Facilities to
                          become repayable before the stated maturity date;
                          and/or

                 (iii)    cause the exercise of a put option under clause 18.1
                          of the Existing Guarantee  (or any similar provision)
                          in circumstances necessitating the making of a
                          payment or payments by a company or companies in the
                          Target Group pursuant to the terms of clause 18 of
                          the Existing Guarantee (or any similar provision);

                 and in any such case either:

                          (aa)    the aggregate amount of Existing Public Debt
                                  or Indebtedness to be repaid under the
                                  Existing Facilities and payments to be made
                                  by a Target Group company (as referred to in
                                  sub-clause (iii)) would exceed the aggregate
                                  of (A) all financing facilities then
                                  available to the Borrowers, Bidco or any
                                  member of the Target Group and (B) all Liquid
                                  Assets less (C) the Headroom; or

                          (bb)    the financial consequences to the Group of
                                  refinancing such Indebtedness as referred to
                                  in (aa) above would be so materially adverse
                                  (whether in terms of coupon, all-in inherent
                                  costs or otherwise) compared with not so
                                  refinancing such Indebtedness as to make it
                                  unreasonable for the Finance Parties to
                                  require guarantees to be given.

         obtain any necessary consents under the Existing Facilities or the
         Existing Public Debt as are needed to enable guarantees by Target
         Group companies in favour of the Security Agent to be given within six

                 not be affected by judgment being obtained for any other sums
                 due under or in respect of any of the Finance Documents and
                 the term "RATE OF EXCHANGE" includes any premium and costs of

                 any Utilisation or to maintain its Commitments in respect of a

                 or regulation or contrary to any request from or requirement
                 of any fiscal monetary or other

                 Finance Party so requires each relevant Borrower shall be
                 obliged to prepay the Contribution of such Finance Party to
                 such Facility and provide full cash cover for any Outstanding
                 Contingent Liabilities of the relevant Finance Party on a
                 future date specified by the Facility Agent not being earlier
                 than the latest date permitted by the relevant law or
                 regulation or not contrary to such request or requirement.

                 Contingent Liabilities of the relevant Finance Party to such
                 Finance Parties but shall place such monies on suspense
                 account and such money may be used as collateral for the
                 actual and the contingent liabilities of that Finance Party to
                 the Issuing Bank, which liabilities shall remain in full force
                 and effect notwithstanding such prepayment; and such Finance
                 Party shall remain liable under all the relevant provisions of
                 this Agreement to the Issuing Bank to pay in cash any
                 shortfall between the amount held by the Facility Agent and

                          (bb)    following such notification the Primary
                                  Borrower shall, whether or not such Finance
                                  Party's Contribution to any Facility has been
                                  repaid, pay to the Facility Agent on demand
                                  for the account of such Finance Party the
                                  amount which such Finance Party specifies (in
                                  a certificate setting forth the basis of the
                                  computation of such amount but not including
                                  any matters which such Finance Party or its
                                  holding company regards as confidential) is
                                  required to compensate such Finance Party
                                  and/or its holding company in its sole
                                  discretion for such liability to Taxes,
                                  increased or additional cost, reduction,
                                  payment, forgone return or loss.

         For the purposes of this clause 14.2 each Finance Party may in good
         faith allocate or spread costs and/or losses among its assets and
         liabilities (or any class thereof) on such basis as it considers
         appropriate.

         Each Finance Party shall use all reasonable endeavours to notify the
         Primary Borrower as soon as reasonably practicable of any such
         increased cost, reduction, payment or forgone return which is to
         result in a demand under clause 14.2(bb).

         For the purposes of this clause 14.2 and clause 14.4 "HOLDING COMPANY"
         means, in relation to a Finance Party, the company or entity (if any)
         within the consolidated supervision of which such Finance Party is
         included.

         For the purposes of this clause 14.2, the Borrowers acknowledge that
         any requirement that the Finance Parties treat interest hereunder as
         anything other than interest shall be a change in law or the
         interpretation thereof.

14.3     EXCEPTIONS

         Nothing in clause 14.2 shall entitle any Finance Party to receive any
         amount in respect of compensation for any such liability to Taxes,
         increased or additional cost, reduction, payment, forgone return or
         loss to the extent that the same:

         (a)     is taken into account in calculating the Additional Cost; or

         (b)     is the subject of an additional payment under clause 8.5; or

         (c)     arises as a consequence of (or of any law or regulation
                 implementing) (i) the proposals for international convergence
                 of capital measurement and capital standards published by the
                 Basle Committee on
<PAGE>   77
                                     - 76 -



                 Banking Regulations and Supervisory Practices in July 1988
                 and/or (ii) any applicable directive of the European Union (in
                 each case) unless it results from any change in, or in the
                 interpretation or application of, such proposals or any such
                 applicable directive (or any law or regulation implementing
                 the same) occurring after the date hereof;  or

         (d)     is attributable to Taxation save where it is recovered under
                 clause 14.2(i); or

         (e)     is attributable to the wilful default or gross negligence of a
                 Finance Party.

         For the purposes of clause 14.3(c) the term "APPLICABLE DIRECTIVE"
         means (exclusively) each of the Own Funds Directive (89/299/EEC of
         17th April 1989) and the Solvency Ratio Directive (89/647/EEC of 18th
         December 1989).

14.4     MITIGATION

         If, in respect of any Finance Party (an "AFFECTED BANK"),
         circumstances arise or exist which would result in:

         (a)     any Borrower being required to make an increased payment to
                 that Finance Party pursuant to clause 8.5;

         (b)     the reduction of that Finance Party's Commitment in respect of
                 any Facility to zero or any Borrower being required to prepay
                 that Finance Party's Contribution to any Facility pursuant to
                 clause 14.1;

         (c)     any Borrower being required to make a payment to any Finance
                 Party to compensate such Finance Party or its holding company
                 for a liability to Taxes, increased or additional cost,
                 reduction, payment, forgone return or loss pursuant to clause
                 14.2(bb); or

         (d)     any Borrower not being entitled to a deduction for UK
                 corporation tax purposes in respect of interest payable under
                 this Agreement to that Finance Party;

         then, without in any way limiting, reducing or otherwise qualifying
         the obligations of any Borrower under clause 8 and this clause 14 (and
         subject to the Borrower's rights under clause 6.5), such Finance Party
         shall, in consultation with the Facility Agent, endeavour to take such
         reasonable steps (and/or, in the case of clause 14.2(bb) and where the
         increased or additional cost, reduction, payment, forgone return or
         loss is that of its holding company, endeavour to procure that its
         holding company takes such reasonable steps) as are open to it (or, as
         the case may be, its holding company) to mitigate or remove such
         circumstances unless the taking of such steps might (in the opinion of
         such Finance Party) be prejudicial to such Finance Party (or, as the
         case may be, its holding company) and provided that such Finance Party
         shall be under no obligation to take any such action if in the opinion
         of such Finance Party to do so might have any adverse effect upon its
         business, operations or financial condition.


15.      SET-OFF AND PRO-RATA PAYMENTS

15.1     SET-OFF

         Each Borrower hereby agrees that each Finance Party may at any time,
         whilst any Default shall be continuing notwithstanding any settlement
         of account or other matter whatsoever, combine or consolidate all or
         any of its then existing accounts wheresoever situate (including
         accounts in the name of such Finance Party or of such Borrower jointly
         with others), whether such accounts are current, deposit, loan or of
         any other nature
<PAGE>   78
                                     - 77 -



         whatsoever, whether they are subject to notice or not and whether they
         are denominated in Sterling or in any other currency, and set-off or
         transfer any sum standing to the credit of any one or more such
         accounts in or towards satisfaction of any moneys, obligations or
         liabilities which are due and payable by such Borrower to such Finance
         Party under the Finance Documents but are unpaid.  For this purpose
         each Finance Party is authorised to purchase with the moneys standing
         to the credit of such account such other currencies as may be
         necessary to effect such application.  No Finance Party shall be
         obliged to exercise any right given to it by this clause 15.1.  Each
         Finance Party shall notify the Facility Agent promptly upon the
         exercise or purported exercise of any right of set-off in relation to
         any member of the Group giving full details in relation thereto and
         the Facility Agent shall inform the other Finance Parties.

15.2     PRO-RATA PAYMENTS

         (a)     If at any time any Bank (the "RECOVERING BANK") receives or
                 recovers any amount owing to it by any Borrower under this
                 Agreement by direct payment, set-off or in any manner other
                 than by payment through the Facility Agent (not being a
                 payment received from a Substitute or a sub-participant in
                 such Bank's Contribution to any Facility or any other payment
                 of an amount due to the Recovering Bank for its sole account),
                 the Recovering Bank shall, within two Banking Days of such
                 receipt or recovery (a "RELEVANT RECEIPT") notify the Facility
                 Agent of the amount of the Relevant Receipt.  If the Relevant
                 Receipt exceeds the amount which the Recovering Bank would
                 have received if the Relevant Receipt had been received by the
                 Facility Agent then:

                 (i)      within two Banking Days of demand by the Facility
                          Agent, the Recovering Bank shall pay to the Facility
                          Agent an amount equal to the excess;

                 (ii)     the Facility Agent shall treat the excess amount so
                          paid by the Recovering Bank as if it were a payment
                          made by the relevant Borrower and shall distribute
                          the same to the Banks (other than the Recovering
                          Bank); and

                 (iii)    as between the relevant Borrower and the Recovering
                          Bank, the excess amount so re-distributed shall be
                          treated as not having been paid but the obligations
                          of the relevant Borrower to the other Banks shall, to
                          the extent of the amount so re-distributed to them,
                          be treated as discharged.

         (b)     If any part of a Relevant Receipt subsequently has to be
                 wholly or partly refunded by the Recovering Bank (whether to a
                 liquidator or otherwise) each Bank to which any part of such
                 Relevant Receipt was so re-distributed shall on request from
                 the Recovering Bank repay to the Recovering Bank such Bank's
                 pro-rata share of the amount which has to be refunded by the
                 Recovering Bank.

         (c)     Each Bank shall on request supply to the Facility Agent such
                 information as the Facility Agent may from time to time
                 request for the purpose of this clause 15.2.

         (d)     Notwithstanding the foregoing provisions of this clause 15.2,
                 no Recovering Bank shall be obliged to share any Relevant
                 Receipt which it receives or recovers pursuant to legal
                 proceedings taken by it to recover any sums owing to it under
                 this Agreement with any other party which has a legal right
                 to, but does not, either join in such proceedings or commence
                 and diligently pursue separate proceedings to enforce its
                 rights in the same or another court (unless the proceedings
                 instituted by the Recovering Bank are instituted by it in
                 breach of clause 18.2).

         (e)     The amounts due from each relevant Borrower to each of the
                 Banks shall reflect any payments and receipts among the Banks
                 prescribed by this clause.
<PAGE>   79
                                     - 78 -




         (f)     Nothing in this clause 15.2 shall prevent the Issuing Bank
                 from recovering from the relevant Borrowers any amounts due
                 under a Letter of Credit issued by the Issuing Bank.

15.3     NO RELEASE

         For the avoidance of doubt it is hereby declared that failure by any
         Recovering Bank to comply with the provisions of clause 15.2 shall not
         release any other Recovering Bank from any of its obligations or
         liabilities under clause 15.2.

15.4     NO CHARGE

         The provisions of this clause 15 are not intended to, shall not, and
         shall not be construed so as to, constitute a charge by a Bank.  In
         particular it is not intended to create a charge over all or any part
         of a sum received or recovered by any Bank in the circumstances
         mentioned in clause 15.2.


16.      ASSIGNMENT, SUBSTITUTION AND LENDING OFFICES

16.1     BENEFIT AND BURDEN

         This Agreement shall be binding upon, and enure for the benefit of,
         the Finance Parties and the Borrowers and their respective successors,
         transferees and assigns.

16.2     NO ASSIGNMENT BY THE BORROWERS

         The Borrowers may not assign or otherwise transfer any of their
         respective rights or obligations under any of the Finance Documents.

16.3     SUBSTITUTION

         Each Bank (an "EXISTING BANK") may at any time assign all or any of
         its rights and benefits under the Finance Documents or novate in
         accordance with clause 16.5 all or any part of its rights, benefits
         and/or obligations under the Finance Documents to another Qualifying
         Bank (a "SUBSTITUTE") with the consent of the Issuing Bank, and with
         the consent of the Primary Borrower (not to be unreasonably withheld
         or delayed), save that such consent of the Primary Borrower will not
         be required to assignments or novations which take place prior to the
         Syndication Date.

16.4     ASSIGNMENT

         If any Bank assigns all or any of its rights and benefits under the
         Finance Documents in accordance with clause 16.3, then, unless and
         until the assignee has agreed with the other Finance Parties that it
         shall be under the same obligations towards each of them as it would
         have been if it had been an original party thereto as a Bank, the
         other Finance Parties shall not be obliged to recognise that assignee
         as having the rights against each of them which it would have had if
         it had been such a party thereto.

16.5     SUBSTITUTION CERTIFICATE

         (a)     Subject to clause 16.5 (b), if a duly completed Substitution
                 Certificate duly executed by the Existing Bank and the
                 Substitute is delivered to and counter-signed by the Facility
                 Agent (for itself and the other parties to this Agreement
                 other than the Existing Bank), then on the Effective Date (as
                 specified in that
<PAGE>   80
                                     - 79 -



                 Substitution Certificate) to the extent that the Existing
                 Bank's rights, benefits and obligations under the Finance
                 Documents are expressed in such Substitution Certificate to be
                 the subject of a novation in favour of the Substitute effected
                 pursuant to this clause 16.5:

                 (i)      the existing parties to the Finance Documents and the
                          Existing Bank shall be released from their respective
                          obligations towards one another under the Finance
                          Documents ("DISCHARGED OBLIGATIONS") except for any
                          obligation which the Existing Bank has to the Issuing
                          Bank under clause 4.7 (Bank's Guarantee and
                          Indemnity) before the date on which the novation
                          takes place unless otherwise agreed in writing by the
                          Issuing Bank and their respective rights against one
                          another under the Finance Documents ("DISCHARGED
                          RIGHTS") shall be cancelled;

                 (ii)     the Substitute party to such Substitution Certificate
                          and the existing parties to the Finance Documents
                          shall assume obligations towards each other which
                          differ from the discharged obligations only insofar
                          as they are owed to or assumed by such Substitute
                          instead of to or by such Existing Bank;

                 (iii)    the Substitute party to such Substitution Certificate
                          and the existing parties to the Finance Documents
                          shall acquire rights against each other which differ
                          from the discharged rights only insofar as they are
                          exercisable by or against such Substitute instead of
                          by or against such Existing Bank; and

                 (iv)     the Finance Parties shall acquire the same rights and
                          benefits and assume the same obligations between
                          themselves as they would have acquired and assumed
                          had such Substitute been an original party hereto as
                          a Bank with the rights, benefits and/or obligations
                          acquired or assumed by it as a result of such
                          transfer;

                 and, on such Effective Date, the Substitute shall (unless such
                 novation is part of the syndication process carried out by the
                 Arrangers) pay to the Facility Agent for its own account a fee
                 of L.750.  The Facility Agent shall promptly notify the other
                 Banks of the receipt by it of any Substitution Certificate and
                 shall promptly deliver a copy of such Substitution Certificate
                 to the Primary Borrower.

         (b)     A Substitution Certificate executed under this clause shall be
                 automatically effective only if and to the extent that the
                 Substitute shall have a credit rating issued by Standard &
                 Poors Corporation of at least A (the "Minimum Rating").  If
                 any Substitute does not have the Minimum Rating as at the time
                 of the transfer, then the Substitution Certificate shall not
                 take effect until such time as the Substitute has lodged with
                 the Security Agent such amount of cash by way of cash cover as
                 would represent the amount required to be paid by that
                 Substitute to the Issuing Bank, if the Issuing Bank were to
                 call on the Bank's indemnity in respect of Letters of Credit
                 contained in clause 4.7.  Should the Issuing Bank issue any
                 further Letters of Credit, such Substitute shall lodge such
                 further cash cover as shall equal the contribution which it
                 could be required to make to the Banks' indemnity in respect
                 of such additional Letters of Credit.

16.6     RELIANCE ON SUBSTITUTION CERTIFICATE

         The Facility Agent (on behalf of itself and the Security Agent) and
         the Borrowers shall be fully entitled to rely on any Substitution
         Certificate delivered to the Facility Agent in accordance with the
         foregoing provisions of this clause 16 which is complete and regular
         on its face as regards its contents and purportedly signed on behalf
         of the relevant Existing Bank(s) and the Substitute(s) and none of the
         Facility Agent, the Security Agent and the Borrowers shall have any
         liability or responsibility to any party as a consequence of placing
         reliance on and
<PAGE>   81
                                     - 80 -



         acting in accordance with any such Substitution Certificate if it
         proves to be the case that the same was not authentic or duly
         authorised.

16.7     AUTHORISATION OF FACILITY AGENT

         Each party to this Agreement irrevocably authorises the Facility Agent
         to counter-sign each Substitution Certificate on its behalf for the
         purposes of clause 16.5 without any further consent of, or
         consultation with, such party except, in the case of the Primary
         Borrower, any consent required pursuant to clause 16.3.

16.8     ACCESSION DEEDS

         The Primary Borrower shall, promptly after demand by the Facility

         connection with the creation of valid security in respect of any
         Substitute taking an assignment of rights and/or an assumption of
         obligations pursuant to clause 16 in those jurisdictions requiring

         If any Bank novates all or any part of its rights, benefits and
         obligations as provided in clause 16.3 all relevant references in this

         such Bank and/or its Substitute to the extent of their respective
         interests.

         (g)     where such information shall have already entered the public
                 domain,

         and in the case of (a) and (b) above, subject to requiring and
         receiving a written confirmation from the recipient of the information
         that it will treat in confidence any confidential information so
         disclosed to it and not use it for any unauthorised purpose and, upon
         receipt of such confirmation, such Finance Party shall in no way be
         liable or responsible for such information not being kept confidential
         by such proposed assignee, Substitute or other person.

16.13    RESTRICTIONS ON NOVATIONS

         Any novation by an Existing Bank which is transferring part (but not
         all) of its Commitment may only be made under this clause 16 if (i) it
         is made in respect of a Commitment of L.5,000,000 or any larger
         integral multiple of L.5,000,000 and (ii) as a consequence of such
         novation (or as a consequence of that and any other novation between
         the same or related parties taking effect at or about the same time)
         the Commitment of the Existing Bank would be less than L.5,000,000.
         If part (but not all) of a Bank's Contribution is being transferred,
         the previous sentence shall be read as if it referred to
         "Contribution", "Contributions" and assignment instead of "Commitment"
         and "Commitments" and "novation" respectively.

16.14    NO OBLIGATION

         The Existing Bank shall not be obliged by any Finance Document to:

         (a)     accept a re-transfer from the Substitute of any of the rights
                 and/or obligations assigned or transferred under this clause
                 16; or

         (b)     indemnify the Substitute for any losses arising by reason of
                 any Obligor's failure to perform its obligations under any
                 Finance Documents or otherwise.

16.15    SYNDICATION

         It is acknowledged that at the date of this Agreement the Facilities
         are being made available by the Underwriters with the intention that
         each Underwriter may transfer any part of its participation in
         accordance with clause 16.5 (Substitution) and, accordingly,
         references to the Banks shall, before the first date on which such
         transfer shall be made of the Underwriter's rights, benefits and
         obligations under this Agreement in accordance with clause 16.5

                 benefit of the Banks any information addressed to any Obligor

                 provided that any such warranties are expressed to be to the
                 best of the relevant Obligor's knowledge, information and
                 belief and that the Obligors may disclose against such

17.      FACILITY AGENT AND SECURITY AGENT

17.1     APPOINTMENT OF FACILITY AGENT AND SECURITY AGENT

         Each Finance Party (except the relevant agent) appoints the Facility
         Agent to act as its agent in connection with the Finance Documents to
         which the Facility Agent is a party and the Security Agent to act as
         its agent and trustee in relation to the Security Documents, and
         authorises each of the Facility Agent and the Security Agent to
         exercise such rights, remedies, powers and discretions as are
         specifically delegated to them by the terms of this Agreement and the
         Security Documents together with all reasonably incidental rights,
         powers and discretions. The Obligors shall be entitled to assume that
         the Facility Agent and the Security Agent represent the Finance
         Parties (except the relevant agent), the Reference Banks or the
         Majority Banks (as the case may be), and that all consents and notices
         given by the Facility Agent or the Security Agent on their behalf are
         validly given.

17.2     SEPARATE TREATMENT OF SYNDICATION DIVISION

         In acting as Facility Agent or Security Agent, the Facility Agent's
         or, as the case may be, the Security Agent's syndication division (or
         such other division as may undertake such task) shall be treated as a
         separate entity from any other of its divisions or departments and,
         despite the provisions of clauses 17 to 21, if the Facility Agent or
         Security Agent or any Related Person acts for or transacts business
         with any member of a group comprising
<PAGE>   84
                                     - 83 -



         the Parent and its Affiliates or associated companies (the "Parent
         Group") or any other person which may be a trade competitor of the
         Parent Group or Target Group or any member of either such group or may
         otherwise have commercial interests similar to those of any member of
         such groups in any capacity in relation to any other matter (including
         as a Bank under this Agreement), any information acquired by the
         Facility Agent or Security Agent or any Related Person in such other
         capacity may be treated as confidential by the Facility Agent or
         Security Agent.  The Borrowers and Bidco hereby expressly acknowledge
         that the Finance Parties and Related Persons may be providing debt
         financing, equity capital or other services (including financial
         advisory services) to other persons with whom the Parent or the Group
         may have conflicting interests in respect of the Facilities or
         otherwise.

17.3     ACTIONS OF FACILITY AGENT AND SECURITY AGENT

         Each action taken or decision made by the Facility Agent or the
         Security Agent under or in relation to any Finance Document with
         requisite authority under this Agreement, including on the basis of
         the requisite instructions, shall be binding on all the Finance
         Parties.

17.4     NOTIFICATION OF RETIREMENT OF FACILITY AGENT, SECURITY AGENT OR
         ISSUING BANK

         Each of the Facility Agent, the Security Agent and/or the Issuing Bank
         may resign its appointment under this Agreement at any time without
         assigning any reason therefor by giving not less than 30 days' prior
         written notice to that effect to each of the other parties to this
         Agreement Provided that no such resignation shall be effective until a
         successor for such Facility Agent, Security Agent or Issuing Bank (as
         the case may be) is appointed in accordance with the succeeding
         provisions of this clause.

17.5     SUCCESSOR FACILITY AGENT, SECURITY AGENT OR ISSUING BANK

         If the Facility Agent, Security Agent or Issuing Bank gives notice of
         its resignation pursuant to clause 17.4, then any reputable and
         experienced bank or other financial institution with an office in
         London may after consultation with the Primary Borrower be appointed
         as a successor to such Facility Agent, Security Agent or Issuing Bank
         (as the case may be) by the Majority Banks but, if no such successor
         is so appointed, the Facility Agent, Security Agent or Issuing Bank
         (as the case may be) may appoint such a successor itself.

         ISSUING BANK

         Issuing Bank and executes such necessary documentation under this
         clause 17:

         (a)     as regards the other Finance Parties and the Obligors, such

                 Issuing Bank and become entitled to all the rights,
                 privileges, powers, authorities and discretions of the
                 Facility Agent, Security Agent or, as the case may be, the
                 Issuing Bank under the Finance Documents;

         (b)     the agency of the retiring Facility Agent, the trusteeship of
                 the retiring Security Agent or, as the case may be, the duties
                 of the Issuing Bank shall terminate and the retiring Facility
                 Agent, Security Agent or, as the case may be, the retiring
                 Issuing Bank shall be discharged from any further liability or
                 obligation under the Finance Documents, but without prejudice
                 to any liabilities which the retiring Facility Agent, Security
                 Agent or, as the case may be, the retiring Issuing Bank may
                 have incurred (including with respect to the retiring Issuing
                 Bank any then outstanding Issued Letter of Credit) before the
                 termination of its agency, trusteeship and/or duties;
<PAGE>   85
                                     - 84 -




         (c)     the costs, charges and expenses of the retiring Facility
                 Agent, Security Agent or, as the case may be, the retiring
                 Issuing Bank shall be discharged if recoverable under the
                 provisions of this Agreement;

         (d)     the provisions of the Finance Documents shall continue in
                 effect for the benefit of any retiring Facility Agent,
                 Security Agent or, as the case may be, the retiring Issuing
                 Bank in respect of any actions taken or omitted to be taken by
                 it or any event occurring before the termination of its
                 agency, trusteeship and/or duties (including with respect to
                 the retiring Issuing Bank any then outstanding Issued Letter
                 of Credit);

         (e)     it is intended that (except only as may be agreed in writing
                 between any retiring Security Agent and its successor with the
                 prior approval of the Majority Banks), in the case of the
                 appointment of successor to the Security Agent, the property,
                 assets and rights vested in the retiring Security Agent
                 pursuant to the Security Documents should, with immediate
                 effect, be vested in such successor Security Agent under the
                 provisions of the Trustee Act 1925, either by operation of law
                 or, failing that, by assignment or other form of transfer or
                 conveyance;

         (f)     at any time and from time to time following such appointment
                 of a successor to the Security Agent, the retiring Security
                 Agent shall do and execute all acts, deeds and documents
                 reasonably required by such successor in order to transfer to
                 such successor Security Agent (or its nominee, as such
                 successor may direct) any such property, assets and rights
                 which shall not have vested in such successor by operation of
                 law and all such acts, deeds and documents under clauses
                 17.6(e) and (f) shall be done or, as the case may be, executed
                 at the cost of the retiring Security Agent; and

         (g)     the retiring Facility Agent, Security Agent or Issuing Bank
                 shall (at the expense of the Primary Borrower) provide its
                 successor with copies of such of its records as its successor
                 reasonably requires to carry out its functions as such.

         be consolidated or any corporation resulting from any merger,
         conversion, amalgamation, consolidation or other reorganisation to
         which the Facility Agent, the Security Agent or the Issuing Bank shall
         be a party shall, to the extent permitted by applicable law, be the
         successor Facility Agent, Security Agent or, as the case may be,
         Issuing Bank under this Agreement and the other Finance Documents (as
         appropriate) without the execution or filing of any document or any
         further act on the part of any of the parties to this Agreement or, as
         the case may be, the other Finance Documents save that notice of
         merger, conversion, amalgamation, consolidation or other
         reorganisation shall forthwith be given to the Primary Borrower and
         the Banks.

         at the request of the Majority Banks to act for such Issuing Bank with
         respect thereto.

                 identified with its signature below (or, in the case of a
                 Substitute, that identified in the Substitution Certificate
                 under which it became a party to this Agreement) until it has
                 received from such Bank a notice designating some other office
                 of such Bank as its Facility Office, and may act upon any such
                 notice until the same is superseded by a further such notice;

         (b)     engage and pay for the advice or services of any lawyers,

                 any advice so obtained;

         (c)     rely as to matters of fact which might reasonably be expected
                 to be within the knowledge of an Obligor upon a certificate or
                 statement signed by or on behalf of that Obligor;

         (d)     rely upon any communication or document believed by it to be

                 by the Majority Banks or, where required, all of the Banks as
                 to whether or not such right, power or discretion is to be
                 exercised and, if it is to be exercised, as to the manner in
                 which it should be exercised, and it shall not be liable for
                 acting or refraining from acting in accordance with or in the
                 absence of such instructions;

         (f)     refrain from taking any step to protect or enforce the rights

                 connection with any Finance Document until it has been
                 indemnified and/or secured as it may require (whether by way
                 of payment in advance or otherwise) against all costs, claims,
                 expenses (including legal fees) and liabilities which it will
                 or may expend or incur in complying with such instructions;

         (g)     refrain from doing anything which would or might in its
                 opinion be contrary to any applicable law or any requirements
                 (whether or not having the force of law) of any governmental,
                 judicial or regulatory body or otherwise render it liable to

                 to comply with any such applicable law or requirement;

         (h)     do any act or thing in the exercise of any of its powers and
                 duties under the Finance Documents which may lawfully be done
                 and which in its absolute discretion it deems advisable for
                 the protection and benefit of the Finance Parties
                 collectively;

         (i)     perform any of its duties, obligations and responsibilities

                 auditors possession of, such documents when necessary or
                 convenient  and, in the absence of gross negligence or wilful

                 contrary to any relevant law of any jurisdiction or any
                 relevant directive or regulation of any agency of any state or
                 which would or might otherwise render it liable to any persons
                 and may do anything which is, in its opinion, necessary or

                 part of the Trust Property or otherwise held by it as a
                 consequence of any enforcement of the security constituted by
                 the Security Documents which, in the opinion of the Facility
                 Agent or (as the case may be) the Security Agent, it would not
                 be practicable to distribute immediately by placing the same
                 on deposit in the name or under the control of itself as it
                 may think fit without being under any duty to diversify the

                 Agreement and the other Finance Documents and upon a receiver

                 Agent by this Agreement and/or any Security Document but so
                 that the Security Agent may only exercise such powers and

                 the provisions of this Agreement;

                 to the Primary Borrower and the Facility Agent of any such
                 appointment; and any person so appointed shall have such

                 payment of money) and such duties and obligations as shall be
                 conferred or imposed on such person by the instrument of

                 any other person to maintain any such insurance and (in the
                 absence of gross negligence or wilful default on the part of
                 the Security Agent) shall not be responsible for any loss
                 which may be suffered by any person as a result of the lack of

                 from acting) in connection with the instructions of the
                 Majority Banks.

20.2     INDEMNITY FROM BANKS

         Each Bank and the Issuing Bank shall, in its Proportion, on demand by
         the Facility Agent, the Security Agent or any Arranger from time to
         time, indemnify the Facility Agent or, as the case may be, the
         Security Agent or the Arranger, against any and all fees (to the
         extent properly chargeable by the Facility Agent or, as the case may
         be, the Security Agent or the Arranger under any Finance Document but
         not promptly recovered from the Obligors), costs, claims and expenses
         and liabilities including any VAT thereon:

         (a)     to which the Facility Agent or, as the case may be, the
                 Security Agent becomes subject by reason of it acting as agent
                 or security trustee; or

         (ii)    incurred by the Facility Agent or, as the case may be, the
                 Security Agent or any attorney, agent, delegate or other
                 person appointed by the Facility Agent or the Security Agent
                 under any Finance Document in relation to or arising out of
                 the taking or holding of any of the security given or created
                 by or pursuant to any of the Finance Documents or in the
                 execution or purported or attempted execution of the rights,
                 trusts, powers, authorities, discretions and obligations
                 vested in it; or

         (iii)   which it is otherwise entitled to recover from any Obligor,

         in each case under any of the Finance Documents or by law, including
         those relating to all actions, proceedings, claims and demands in
         respect of any matter or thing done or omitted in any way relating to
         the Finance Documents any exercise or non exercise of any right, power
         or discretion, and all amounts due to the Facility Agent or the
         Security Agent by way of remuneration for acting as agent or trustee
         (as the case may be) under any of the Finance Documents (collectively
         the "LIABILITIES").   Each Borrower shall counter-indemnify the Banks
         and the Issuing Bank against all payments by them under this clause
         20.2. If a Bank or the Issuing Bank (referred to in this clause 20.2
         as a "defaulting Bank") fails to pay its due contribution under this
         indemnity, then the Facility Agent or, as the case may be, the
         Security Agent may (without prejudice to its other rights and
         remedies) deduct the amount due from the defaulting Bank from any sums
         which are then or afterwards in its possession which would otherwise
         be payable to the defaulting Bank.

20.3     INDEMNITY FROM TRUST PROPERTY

         The Security Agent and every employee, officer, trustee or co-trustee
         or other person appointed by it in connection with its appointment
         under the Security Documents (each a "PROTECTED PARTY") shall be
         entitled to be indemnified out of the Trust Property in respect of all
         liabilities, damages, costs, claims, charges or expenses whatsoever
         properly incurred or suffered by any Protected Party:

         (a)     in the execution or exercise or bona fide purported execution
                 or exercise of the trusts, rights, powers, authorities,
                 discretions and duties created or conferred by or pursuant to
                 the Security Documents;

         (b)     as a result of any breach by a member of the Group of any of
                 its obligations under any Security Document;

         (c)     in respect of any Environmental Claim made or asserted against
                 a Protected Party which would not have arisen if the Security
                 Documents had not been executed; and
<PAGE>   95
                                     - 94 -




         (d)     in respect of any matter or thing done or omitted in any way
                 relating to the Trust Property or the provisions of any of the
                 Security Documents.

         The rights conferred by this clause 20.3 are without prejudice to any
         right to indemnity by law given to trustees generally and to any
         provision of the Security Documents entitling the Security Agent or
         any other person to an indemnity in respect of, and/or reimbursement
         of, any liabilities, damages, costs, claims, charges or expenses
         incurred or suffered by it in connection with any of the Security
         Documents or the performance of any duties under any of the Security
         Documents.  Nothing contained in this clause 20.3 shall entitle any
         Protected Party to be indemnified in respect of any liabilities,
         damages, costs, claims, charges or expenses to the extent that the
         same arise from such person's own gross negligence or wilful
         misconduct.

20.4     DISCLAIMER

         Neither the Facility Agent, the Security Agent, nor any Arranger or
         Underwriter accepts responsibility to any other Finance Party for the
         accuracy and/or completeness of any information supplied in connection
         with any Finance Document or for the legality, validity,
         effectiveness, adequacy or enforceability of any Finance Document and
         neither the Facility Agent, the Security Agent, nor any Arranger or
         Underwriter shall be under any liability to any other Finance Party as
         a result of taking or omitting to take any action in relation to any
         Finance Document (except in the case of its gross negligence or wilful
         misconduct).

20.5     NO ACTIONS AGAINST INDIVIDUALS

         Each of the Banks agrees that it will not assert or seek to assert
         against any director, officer or employee of the Facility Agent, the
         Security Agent, any Arranger or Underwriter any claim it may have
         against any of them in respect of the matters referred to in clause
         20.4.

20.6     CREDIT APPRAISALS

         It is agreed by each Bank, by virtue of its execution of this
         Agreement or its accession to this Agreement, that it has itself been,
         and will continue to be, solely responsible for making its own
         independent appraisal of and investigations into the financial
         condition, creditworthiness, condition, affairs, status and nature of
         each member of the Group, and, accordingly, each Bank confirms to the
         Facility Agent, the Security Agent, and each Arranger and Underwriter
         that it:

         (a)     does not enter into this Agreement nor accede to it on the
                 basis of and has not relied on and will not rely on any

                 negligent or innocent) or warranty or other provision (in any
                 case whether oral, written, express or implied) made by, or
                 agreed to, the Facility Agent, the Security Agent, any
                 Arranger, any Underwriter or any other Bank to induce it to
                 enter into this Agreement or any other Finance Document except
                 as expressly set out therein and the remedies available in
                 respect of any such misrepresentation or untrue statement made
                 to such Bank shall be limited to a claim for breach of
                 contract under this Agreement; and

         (b)     has not relied on and will not rely on the Facility Agent, the
                 Security Agent, any Arranger, any Underwriter or any other
                 Bank:

                 (i)      to check or enquire on its behalf into the adequacy,
                          accuracy or completeness of any information provided
                          by or on behalf of any member of the Group in
                          connection with any Finance Document and/or the
                          transactions contemplated in the Finance Documents

                          by the Facility Agent, the Security Agent, any
                          Arranger or Underwriter or as the case may be any
                          other Bank); or

                 (ii)     to assess or keep under review on its behalf the

                          affairs, status or nature of any member of the Group.

         Provided that clause 20.6(a) shall not apply to any statement or
         representation made fraudulently, or to any provision of this
         Agreement which was induced by fraud for which the remedies available
         shall be all those available under English law.

20.7     EXONERATION OF RELATED PERSONS

         All the provisions of this clause 20 and of any other provision of any
         Finance Document protecting (including indemnifying) or limiting the
         liability of any Finance Party, or exonerating it from liability or
         responsibility, which may enure to the benefit of the such Finance
         Party shall also be deemed to be given for the benefit of the Security
         Agent and all Related Persons to whom they are capable of relating or
         in respect of whom they are capable of taking effect.

20.8     PRE-CONTRACTUAL EFFECT OF EXONERATION

         For the avoidance of doubt, the guarantee, indemnity, exonerations and
         other protections in favour of the Facility Agent, the Security Agent,

         the Finance Documents shall take effect in respect of all events,
         action and omissions occurring before the execution and completion of
         this Agreement as well as events, actions and omissions occurring on
         or after its execution and completion and to the extent that any
         liability should be adjudged to have arisen prior to the date of this
         Agreement, such liability is hereby completely released.

20.9     COMMON PARTIES

         Notwithstanding that the Facility Agent and the Security Agent may
         from time to time be the same entity, the Facility Agent and the
         Security Agent have entered into this Agreement in their separate
         capacities as agent or (as appropriate) security agent and trustee for
         the Finance Parties provided that, where this Agreement provides for
         the Facility Agent or Security Agent to communicate with or provide
         instructions to another Facility Agent or Security Agent while the two
         parties in question are the same entity, it will not be necessary for
         there to be any such formal communication or instructions.


21.      ENFORCEMENT AND RECOVERIES

21.1     OBLIGATIONS OWED BY OBLIGORS TO FINANCE PARTIES

         Each Obligor agrees that:

         (a)     the security comprised in the Security Documents may be
                 enforced, realised and distributed by the Security Agent and
                 Facility Agent in accordance with their respective powers and
                 obligations to the Finance Parties set out in clauses 18 and
                 19;

         (b)     the obligations and liabilities the subject of the Security
                 Documents shall only be discharged by virtue of receipt or
                 recovery by the Security Agent of monies, or of payments made
                 by the Security Agent
<PAGE>   97
                                     - 96 -



                 hereunder, to the extent that the ultimate recipient actually
                 receives monies from the Security Agent hereunder;

         (c)     if it receives any sum from any person which, pursuant to the
                 Finance Documents, should have been paid to the Security
                 Agent, such sum shall be held on trust for the Finance Parties
                 and shall forthwith be paid over to the Security Agent;

         (d)     it hereby waives, to the extent permitted under applicable
                 law, all rights it may otherwise have to require that the
                 security created pursuant to the Facility Documents be
                 enforced in any particular order or manner or that any sum
                 received or recovered from any  person or by virtue of the
                 enforcement of any of the security or any other Encumbrance of
                 any nature over any assets or revenues, which is capable of
                 being applied in or towards discharge of any of the Secured
                 Obligations is so applied, whether on receipt or recovery or
                 at any time thereafter.

         AGENT

         The Finance Parties agree between themselves:

         (a)     to furnish to the Facility Agent, for transmission to the
                 Security Agent, such information as the Security Agent may
                 reasonably specify (through the Facility Agent) as being
                 necessary or desirable for the purpose of enabling the
                 Security Agent to perform its functions as trustee or
                 administrator;

         (b)     to co-operate with each other and with the Security Agent and
                 any Receiver under the Security Documents in realising the
                 property and assets subject to the Security Documents and in
                 ensuring that the net proceeds realised under the Security
                 Documents after deduction of the expenses of realisation are
                 applied in accordance with clause 19.1; and

         (c)     not to take any action separately to enforce or attempt to
                 enforce any of the Security Documents or to exercise any
                 rights, discretions or powers or to grant any consents or
                 releases under or pursuant to any of the Security Documents or
                 otherwise have direct recourse to the security and/or
                 guarantees constituted by any of the Security Documents.

22.1     MAJORITY BANK MATTERS: AMENDMENTS AND WAIVERS

         Except as provided in clause 22.4 and 22.5 (Unanimous consent), with
         the prior written consent of the Majority Banks, the Facility Agent

                 any manner the rights and/or obligations of any of the
                 Borrowers, the Facility Agent, the Security Agent and the
                 Banks; and

         (b)     execute and deliver to any Borrower a written instrument
                 waiving prospectively or retrospectively, on such terms and
                 conditions as the Facility Agent (or, as the case may be,
                 Security Agent) may specify in such instrument, any of the
                 requirements of any of the Finance Documents, or giving any
                 consents or approvals thereunder.

         determine, shall be promptly notified to the Banks by the Facility

         and any other members of the Group and generally administer the
         Advances in accordance with the wishes of the Majority Banks.  All the
         Banks shall be bound by the provisions of this clause 22.3 and no Bank

         vary or waive breaches of or defaults under or otherwise excuse
         performance of any provision of this Agreement by any Obligor, if the

         (b)     postpone the due date or reduce the amount of any payment of
                 principal, interest, commitment commission or other amount

         (i)     change this clause 22 or clause 23.

22.5     ALL BANK MATTERS: SECURITY

         Except with the prior written consent of all the Banks, the Facility
         Agent shall not have authority on behalf of the Banks to authorise the
         Security Agent to agree amendments or modifications to the Security
         Documents with the members of the Group (or the Parent on their
         behalf) and/or vary or waive breaches of, or defaults under, or
         otherwise excuse performance of, any provision of any of the Security

                 by any Security Document;

         (b)     release any of the Charged Assets from the security
                 constituted by any Security Document other than any such

                 Period has terminated;

         (c)     agree with the Parent or any other member of the Group any
                 amendment of, or action in relation to, any of the Security

         adherence by a new Subsidiary or other Obligor or proposed Obligor or
         any deed or instrument pursuant to a further assurance provision in
         this Agreement or the other Finance Documents shall not constitute an
         amendment or modification to, or variation of, any of the Finance
         Documents.

22.7     VETO OF SECURITY AGENT AND FACILITY AGENT

         Regardless of any other provision in this Agreement, the Facility
         Agent, or as the case may be, the Security Agent, shall not be obliged

         (b)     otherwise amend, modify or waive any of the Facility Agent's,

23.      BASIS OF DECISIONS

23.1     MEANING OF MAJORITY BANKS

         Where this Agreement or any of the Security Documents provides for any
         matter to be determined by reference to the opinion of, or to be
         subject to the consent or request of, the Majority Banks or for any
         action to be taken on the instructions of the Majority Banks, such
         opinion, consent, request or instructions shall (as between the Banks)
         only be regarded as having been validly given or issued by the
         Majority Banks if all the Banks shall have received prior notice of
         the matter on which such opinion, consent, request or instructions are
         required to be obtained and the relevant majority of Banks shall have
         given or issued such opinion, consent, request or instructions, but so
         that (as between the Obligors and the Finance Parties) the Obligors
         shall each be entitled (and bound) to assume that such notice shall
         have been duly received by each Bank and that the relevant majority
         shall have been obtained to constitute Majority Banks when notified to
         this effect by the Facility Agent whether or not this is the case.

23.2     NOTICE TO MAJORITY BANKS

         If, within 10 Banking Days (or in the case of any approval sought
         under clause 10.4, 2 Banking Days) of the Facility Agent despatching
         to each Bank a notice requesting instructions (or confirmation of
         instructions) from the Banks or the agreement of the Banks to any
         amendment, modification, waiver, variation or excuse of performance
         for the purposes of, or in relation to, any of the Finance Documents,
         the Facility Agent has not received a reply specifically giving or
         confirming or refusing to give or confirm the relevant instructions
         or, as the case may be, approving or refusing to approve the proposed
         amendment, modification, waiver, variation or excuse of performance,
         then (subject to clause 23.4) the Facility Agent shall treat any Bank
         which has not so responded as having indicated a desire to be bound by
         the wishes of 66 2/3 per cent. of those Banks (measured in terms of
         the relevant Contributions or, if none, the relevant Commitments of
         those Banks) which have so responded.  Any Bank which notifies the
         Facility Agent of a wish or intention to abstain on any particular
         issue shall be treated as if it had not responded.

23.3     MEANING OF ALL BANKS

         Where this Agreement or any other Finance Document, provides for any
         matter to be determined by reference to the opinion of, or to be
         subject to the consent of or request of all of the Banks or the Banks
         acting unanimously or for any action to be taken on the instruction of
         all the Banks such opinion, consent, request or instructions shall (as
         between the Banks) only be regarded as having been validly given or
         issued by all the Banks (or the Banks acting unanimously) if all the
         Banks shall have received prior notice (the "AGENT'S NOTICE") of such
         matter containing a request for written instructions from such Bank to
         be received by the Facility Agent or, as the case may be, the Security
         Agent within ten Banking Days of the receipt (or the deemed receipt
         pursuant to clause 25.1(b)) of the Agent's Notice.  If, in respect of
         a Bank, the Facility Agent or the Security Agent, as appropriate:

         (a)     shall not have received written instructions in respect of
                 such matter from such Bank; and

         (b)     the Facility Agent or Security Agent shall have received
                 written instructions in respect of such matter from at least
                 five other Banks,

         in each case within such time period (and subject to clause 23.4),
         such Bank shall be deemed to have irrevocably renounced and waived its
         right to make any such determination, approval, consent or provide
         instructions to the Facility Agent or the  Security Agent in respect
         of such matter; shall not have any rights, recourse or remedy against
         the Facility Agent or the Security Agent in respect of such matter;
         and shall be bound (as shall each of the Obligors) by the
         determination, approval, consent or instructions of the other Banks in
         respect of such
<PAGE>   101
                                    - 100 -



         matter.  Clauses 23.1 and 23.2 shall not apply in relation to those
         matters which are to be decided by all the Banks.

23.4     LATE RESPONSES

         In any case where a Bank fails to respond within the time limit set
         down under clauses 23.2 or 23.3, such Bank's response, if it responds
         before any determination or instruction is acted upon or communicated
         to any Obligor, will be taken into account as if it had been received
         within the time limit Provided that the Facility Agent has received
         actual notice of such response before any such action or
         communication.

23.5     COSTS

         If any Borrower requests, or if the Facility Agent requires in
         accordance with clause 10.3(c) or any other provision of this
         Agreement, any amendment, supplement, modification or waiver under
         clause 22.1 (Majority Bank matters) or clauses 22.4 or 22.5 (All Bank
         matters), then the Borrowers shall, on demand by the Facility Agent,
         reimburse the Facility Agent for all costs and expenses (including
         legal fees), together with any VAT on them, incurred by the Facility
         Agent in the negotiation, preparation and execution of any written
         instrument contemplated by clause 22.1 (Majority Bank matters) or
         clauses 22.4 or 22.5 (All Bank matters).

23.6     NO PARTNERSHIP

         This Agreement shall not and shall not be construed so as to
         constitute a partnership between the parties or any of them.

23.7     CHANGE OF REFERENCE BANKS

         If:

         (a)     the whole of the Contributions (if any) of any Reference Bank
                 are prepaid;

         (b)     the Commitments (if any) of any Reference Bank are reduced to
                 zero prior to the end of the Finance Period;

         (c)     a Reference Bank novates the whole of its rights and
                 obligations (if any) as a Bank under this Agreement; or

         (d)     a Reference Bank ceases to provide quotations to the Facility
                 Agent upon request for the purposes of determining LIBOR
                 (where such quotations are required having regard to the
                 definition of "LIBOR" in clause 1.2)

         the Facility Agent may, acting on the instructions of the Majority
         Banks, terminate the appointment of such Reference Bank and after
         consultation with the Primary Borrower  appoint another Bank to
         replace such Reference Bank.

24.      MATTERS CONCERNING THE BORROWERS

24.1     ADDITIONAL BORROWER

         The Primary Borrower may, at any time during the term of this
         Agreement (unless a Default shall have occurred and be continuing),
         notify the Facility Agent that a Permitted Borrower is to be
         designated as an additional Borrower under the Revolving Credit
         Facility.  Such notice shall be in writing and signed by the Primary
         Borrower and the relevant Permitted Borrower and shall take effect in
         accordance with its terms on the condition that:

         (a)     such Permitted Borrower shall have entered into an Accession
                 Certificate with the Facility Agent which, subject to (b)
                 below, the Facility Agent shall execute on behalf of all the
                 parties to this Agreement (and all such parties so authorise
                 the Facility Agent without any further consent of, or
                 consultation with, such party); and

         (b)     such Permitted Borrower, before entering into such an

                 conditions precedent, as notified to the Primary Borrower by
                 the Facility Agent, to the satisfaction of the Facility Agent
                 including the delivery to the Facility Agent of the documents
                 and evidence referred to in Part C of Schedule 3 in form and
                 substance satisfactory to the Facility Agent.

         Upon satisfaction of such conditions such Permitted Borrower shall
         become a party to this Agreement in the capacity of a Borrower in
         respect of the Revolving Credit Facility and shall assume all the
         obligations and rights of such a Borrower under this Agreement.

24.2     PRIMARY BORROWER AS OBLIGORS' AGENT

         Each Obligor by its execution of this Agreement or an Accession
         Certificate, as the case may be, irrevocably appoints and authorises
         the Primary Borrower:

         (a)     as agent for each Borrower and Bidco to receive all notices,
                 requests, demands or other communications under this Agreement
                 which shall, without prejudice to any other effective mode of
                 serving the same, be properly served on the Obligor concerned
                 if served on the Primary Borrower in accordance with clause
                 25.1; and

         (b)     to give all notices (including any Drawdown Notices) and
                 instructions and make such agreements expressed to be capable
                 of being given or made by such Obligor or Obligors in this
                 Agreement (including an agreement for the continuance of any
                 guarantee or security) notwithstanding that they may affect
                 such Obligor without further reference to, or the consent of,
                 such Obligor and such Obligor shall, as regards the Finance
                 Parties, be bound thereby as though such Obligor itself had
                 given such notice or instructions or made such agreement.

24.3     OBLIGATIONS UNCONDITIONAL

         The obligations of each Obligor under this Agreement and the Security
         Documents are unconditional and irrevocable (subject to the express
         provisions of this Agreement or any Security Document) and shall not
         be in any way affected or discharged by reason of any matter affecting
         the Offer or the Acquisition (or the Offer Documents).  Each Obligor
         acknowledges that any approval or authorisation given under this
         Agreement or a Security Document by a Finance Party in relation to the
         Offer or the Acquisition (or the Offer Documents) shall not constitute
         any representation or warranty by such (or any) Finance Party as to
         the adequacy or effectiveness of such Offer or the Acquisition (or the
         Offer Documents), the purchase consideration payable by Bidco, the
         commercial advisability of any Obligor or Bidco entering into the
         arrangements contemplated thereby or otherwise.

24.4     OBLIGATIONS SEVERAL

         The obligations of each Obligor under this Agreement and the Security
         Documents are several and the failure of any Obligor to perform such
         obligations shall not release any other Obligor of its obligations
         under this Agreement.

24.5     STAND-ALONE REVOLVING CREDIT FACILITY TO REC

         The Finance Parties and the Obligors agree that they shall as soon as
         reasonably practicable after the date of the Press Release agree the
         form of an agreement for a stand-alone revolving credit facility to be
         made available by the Banks to REC (the "REC Facility Agreement").
         The REC Facility Agreement shall be entered into between the Finance
         Parties and REC upon the Unconditional Date and, upon such date, the
         Commitment of each Bank in respect of the Revolving Credit Facility
         shall reduce by an amount equal to the commitment assumed by such Bank
         under the REC Facility Agreement.  The REC Facility Agreement shall be
         on terms and subject to conditions identical, mutatis mutandis, to the
         terms and conditions of the Revolving Credit Facility as set out
         herein save that it shall:

         (a)     create a commitment on the part of each of the Banks (pro rata
                 to their respective Proportions) of an aggregate amount of
                 L.250,000,000;

         (b)     be available for the general corporate purposes of REC;

         (c)     have an Applicable Fees Rate of 0.25% and an Applicable Margin
                 of 0.50%;

         (d)     contain no covenants, representations and warranties or events
                 of default referencing any person other than REC and that all
                 such covenants, representations and warranties and events of
                 default shall be confined to, and to events occurring in
                 respect of, the REC (but otherwise corresponding where
                 applicable, to the covenants, representations and warranties
                 and events of default in this Agreement which by their terms
                 herein operate to include the REC Group) and without
                 limitation to the above the following clauses shall not appear
                 in the REC Facility Agreement: 9.2, 10.2(e), (f), (g), 10.4,
                 10.5, 10.6, 11.1(f), 12.1(o)(i), (ii) or (iii), 12.1(w), and
                 any covenant contained in clause 10.3 shall be replaced by the
                 covenant in clause 20.14(b) of the agreement between the
                 Target, Citibank International plc (as agent), Barclays Bank
                 PLC and Midland Bank plc dated 5 August 1996.

         Following such stand-alone REC facility being executed:

                 (i)      the Revolving Credit Facility shall reduce by the
                          principal amount of the commitment created under such
                          stand-alone REC facility; and

                 (ii)     amounts committed or outstanding thereunder shall not
                          be deemed to be committed or outstanding under this
                          Agreement.

                                   SCHEDULE 4

                         CALCULATION OF ADDITIONAL COST

1.       The Additional Cost for any period shall (subject to paragraph 5 
         below) be calculated in accordance with the following formula:

                   BY + L(Y X) + S(Y Z)  per cent per annum
                   --------------------
                                    100 (B + S)

         where on the day of application of the formula:

         B       is the percentage of the Facility Agent's eligible liabilities
                 which the Bank of England then requires the Facility Agent to
                 hold on a non-interest-bearing deposit account in accordance
                 with its cash ratio requirements;

         Y       is the rate at which Sterling deposits are offered by the
                 Facility Agent to leading banks in the London Interbank Market
                 at or about 11 a.m. on that day for the relevant period;

         L       is the percentage of eligible liabilities which (as a result
                 of the requirements of the Bank of England) the Facility Agent
                 maintains as secured money with members of the London Discount
                 Market Association or in certain marketable or callable
                 securities approved by the Bank of England;

         X       is the rate at which secured Sterling investments may be
                 placed by the Facility Agent with members of the London
                 Discount Market Association at or about 11 a.m. on that day
                 for the relevant period or, if greater, the rate at which
                 Sterling bills of exchange (of a tenor equal to the duration
                 of the relevant period) eligible for rediscounting at the Bank
                 of England can be discounted in the London Discount Market at
                 or about 11 a.m. on that day;

         S       is the percentage of the Facility Agent's eligible liabilities
                 which the Bank of England requires the Facility Agent to place
                 as a special deposit; and

         Z       is the interest rate expressed as a percentage per annum
                 allowed by the Bank of England on special deposits.

2.       For the purpose of this schedule 4:

2.1      "ELIGIBLE LIABILITIES" and "SPECIAL DEPOSITS" have the meanings given 
         to them at the time of application of the formula by the Bank of 
         England; and

2.2      "RELEVANT PERIOD" in relation to each period for which Additional Cost
         falls to be calculated means:

          (a)    if it is 3 months or less, that period; or

          (b)    if it is more than 3 months, 3 months.

2.3       In the application of the formula, B, Y, L, X, S and Z are included 
          in the formula as figures and not as percentages, e.g. if B = 0.5 
          per cent and Y = 15 per cent BY is calculated as 0.5 x 15.
<PAGE>   116
                                    - 115 -



2.4      The formula shall be applied on the first day of each relevant
         period.  Each amount shall be rounded up to the nearest four decimal
         places.

2.5      If the Facility Agent determines that a change in circumstances has 
         rendered, or will render, the formula inappropriate, the Facility Agent
         (after consultation with the Banks) shall notify the Primary Borrower
         of the manner in which the Additional Cost will subsequently be
         calculated. The manner of calculation so notified by the Facility Agent
         shall, in the absence of manifest error, be binding on all the parties.

                          (REFERRED TO IN CLAUSE 16.5)

NB       1.      Banks are advised not to employ Substitution Certificates or
                 otherwise to assign, novate or transfer interests in the
                 Agreement without first ensuring that the transaction complies
                 with all applicable laws and regulations, including the
                 Financial Services Act 1986 and regulations made thereunder.

         2.      It is expected that Banks will enter into separate
                 arrangements dealing with the monies to be paid to the
                 Existing Bank by the Substitute in consideration of the
                 novation (e.g. principal, accrued interest, fees and any
                 mismatched funding adjustment).  Unless the Effective Date is
                 a rollover date, mismatches of parties' funding may arise.
                 This Certificate does not deal with these issues, nor does it
                 deal with any interim risk participation the Existing Bank may
                 grant to the Substitute pending the Effective Date.




To:      [NAME OF FACILITY AGENT] on its own behalf, as Facility Agent and on
         behalf of each other party to the Agreement mentioned below.

                   Substitution Certificate;

         (c)       that it has made and will continue to make, without reliance
                   on the Existing Bank or any other Finance Party, and based on
                   such documents as it considers appropriate, its own appraisal
                   of the creditworthiness of any Borrower and the Group and its
                   own independent investigation of the financial condition,

                   connection with the making and continuation of the Facilities
                   under the Agreement and the other Finance Documents;

         (d)       that neither the Existing Bank nor any other Finance Party

                   responsibility, either historically, initially or on a
                   continuing basis, to provide the Substitute with any credit
                   or other information with respect to any Borrower or any
                   other member of the Group whether coming into its possession
                   before the making of any Advance or at any time or times
                   thereafter, other than (in the case of the Facility Agent) as
                   provided in clause 19.1 of the Agreement;

         (e)       that it has made and will continue to make its own assessment
                   of the legality, validity, enforceability and sufficiency of
                   the Agreement, the Security Documents, any other Finance
                   Document and this Substitution Certificate and has not relied
                   and will not rely on the Existing Bank or any other Finance
                   Party or any statements made by any of them in that respect;

         (f)       that, accordingly, none of the Existing Bank nor any other
                   Finance Party makes any representations or warranties in
                   respect of, or shall have any liability or responsibility to
                   the Substitute in respect of, any of the foregoing matters or
                   any other matter referred to in clause 20 of the Agreement;

         (g)       that it is a Qualifying Bank; and

         Parties, the Borrowers and each of the other parties to the Agreement
         that it will perform in accordance with its terms all those obligations
         which by the terms of the Agreement will be assumed by it after
         counter-signature of this Substitution Certificate by the Facility
         Agent.

         indemnifies the Issuing Bank as required under clause 4.7 (Banks'
         Guarantee and Indemnity).

7.       Without limiting the above paragraphs, nothing in this Substitution
         Certificate obliges the Existing Bank to:

         (a)       accept any re-transfer from the Substitute of any of the
                   rights, benefits and/or obligations hereby transferred; or

         (b)       support any losses incurred by the Substitute by reason of
                   any non-performance by the Borrowers or any other party to

                   document relating thereto of any of its obligations under the

         (a)     each Borrower will at all times on demand indemnify the
                 Issuing Bank against all actions, suits, proceedings, claims,
                 demands, liabilities, damages, costs, expenses, losses and

                 Credit and each Borrower will pay to the Facility Agent for
                 the account of the Issuing Bank in immediately available funds
                 and in the currency in which the relevant Letter of Credit is

                 Credit and any of the indemnities relating thereto;

         (a)     the liability of each Borrower under this indemnity shall not
                 be affected by any time being given or by anything being done
                 by the Issuing Bank unless the same constitutes the gross
                 negligence or wilful misconduct of the Issuing Bank.

2.       Each of the Borrowers specifically releases and indemnifies the
         Issuing Bank against the consequences of:

                 despatched; and

         (b)     any delay that may occur during the course of the transmission
                 of any such message

         save in respect of any failure arising from the gross negligence or
         wilful misconduct of the Issuing Bank.

3.       (a)     The obligations of any Borrower under this Agreement and any
                 L/C-Related Document to reimburse the Issuing Bank for a
                 drawing under a Letter of Credit and to repay any drawing
                 under a Letter of Credit which is converted into Advances,
                 shall be unconditional and irrevocable, and shall be paid

                 each such other L/C-Related Document under all circumstances,
                 including the following:

                 (i)      any lack of validity or enforceability of this
                          Agreement or any L/C-Related Document;

                 (ii)     any change in the time, manner or place of payment

                          Letter of Credit (or any person for whom any such
                          beneficiary or any such transferee may be acting),

                          including any other circumstance that might otherwise
                          constitute a defence available to, or a discharge of,
                          the relevant Borrower;

         (b)     The obligations of each of the Borrowers under the Senior

                 (i)      to the Issuing Bank by any beneficiary of any Letter
                          of Credit; or

                          seek reimbursement in respect of sums paid out by it
                          under any Letter of Credit or any other obligation
                          pursuant thereto or pursuant to this Agreement, as
                          the case may be.

4.       The Issuing Bank may, at any time, without affecting any security
         created by, pursuant to or in relation to this Agreement or the
         rights, powers and remedies conferred upon it by this Agreement, any
         such security or by law:

         (a)     offer or agree to or enter into agreement for the extension or
                 variation of the Issue of any Letter of Credit (provided it

                 Borrower); or

         (b)     offer or agree to give any time or other indulgence for any
                 sums paid out by it under any Letter of Credit or any

5.       Any rights conferred on the Issuing Bank by this Agreement and by each

         to and not in substitution for or derogation of any other rights which
         the Issuing Bank may at any time have to seek from any person
         reimbursement of or indemnification against payments made or
         liabilities incurred under any Letter of Credit, any obligation
         pursuant thereto or to this Agreement.

6.       Any satisfaction of obligations by any Borrower or any other person to
         the Issuing Bank or any discharge given by the Issuing Bank to any
         Borrower or any other person in respect of obligations under this
         Agreement or any related agreement between the Issuing Bank and any
         Borrower or any other person shall be, and be deemed always to have
         been, void if any act satisfying any of such obligations or on the
         faith of which any such discharge was given or any such agreement was
         entered into is subsequently avoided by law (otherwise than as a
         result of any act or default by the Issuing Bank).

7.       Any Letter of Credit shall be considered to be outstanding until the
         later of:

         (a)     its Expiry Date, or a reasonable time after its Expiry Date to
                 allow for the presentation of documents through an advising
                 bank; and

         (b)     if, in the opinion of the Issuing Bank, its liability under
                 the Letter of Credit does not expire on its stated Expiry Date
                 or there is any doubt as to its Expiry Date, the date of
                 return of the document evidencing the Issuing Bank's liability
                 to the relevant beneficiary under any Letter of Credit.

8.       Each Borrower confirms and agrees that:

         (a)     the Issuing Bank shall make any payment that appears to be
                 duly requested or demanded in writing by any beneficiary under
                 any Letter of Credit subject to its compliance (where
                 applicable) with its obligations as Issuing Bank under the
                 UCPDC regardless of whether or not the relevant Borrower shall
                 be in any way in breach of any of its obligations under or by
                 virtue of the transaction in connection with which the Letter
                 of Credit was Issued and without making any further reference
                 to the relevant Borrower or any investigation as to the bona
                 fide nature, validity or genuineness of any such request or
                 demand (unless, under applicable law, the Issuing Bank is
                 under no obligation to make such payment), and

         (b)     the liability of such Borrower hereunder and the right and
                 obligation of the Issuing Bank to make such payment shall be
                 in no way diminished or prejudiced if it should appear that,
                 as between the relevant Borrower and that beneficiary, that
                 beneficiary was not entitled for whatever reason to demand
                 payment under the Letter of Credit or that such demand was not
                 valid or genuine (subject as mentioned in paragraph 8(a)
                 above).

                                   SCHEDULE 8

                   TERMS OF INTERBANK GUARANTEE AND INDEMNITY


1.       Each Bank agrees to pay to the Facility Agent for the account of the
         Issuing Bank on demand made through the Facility Agent under clause
         4.7 (Banks' Guarantee and Indemnity) to such account as the Facility
         Agent may have specified for the purpose in immediately available
         funds and in the currency in which the relevant Letter of Credit is
         denominated, its Proportion of:

         (a)     any and every sum of money which such Borrower shall from time
                 to time be liable to pay to the Issuing Bank in respect of
                 that Letter of Credit in full without set-off or counterclaim
                 on the later of the date that the Issuing Bank has itself to
                 make payment under the Letter of Credit (as notified by the
                 Facility Agent to such Bank in the demand) and two Banking
                 Days after receipt by such Bank of such demand; and

         (b)     full cash cover for the Outstanding Contingent Liabilities
                 under that Letter of Credit at any time after the Issuing Bank
                 has become entitled to demand an indemnity through the
                 Facility Agent in respect thereof from the relevant Borrower
                 and which shall not have been paid at the time such demand is
                 made.

2.       Where a Bank makes a payment pursuant to paragraph 1 after the date on
         which the Issuing Bank makes the relevant payment under the Letter of
         Credit in question, such Bank shall pay on demand to the Issuing Bank
         its Proportion (as calculated in clause 4.7) of such amount as the
         Issuing Bank certifies as necessary to compensate it for funding the
         amount demanded in the interim.

3.       No assurance, security or payment avoided under any law relating to
         bankruptcy, liquidation, insolvency, reconstruction or reorganisation
         or any similar laws and no release, settlement, arrangement or
         discharge which may have been given or made on the basis of any such
         assurance, security or payment shall prejudice or affect the right of
         the Issuing Bank to recover from each of the Banks to the full extent
         of their obligations under clause 4.7.

4.       The obligations of each Bank under clause 4.7 shall not be impaired,
         affected or revoked by any act, omission, matter, thing or
         circumstance whatsoever which but for this provision might operate to
         release or exonerate such Bank from all or any part of its obligations
         under clause 4.7 or reduce, impair or affect such obligations or cause
         all or any part of such obligations to be irrecoverable from or
         unenforceable against any Obligor or to discharge, reduce, affect or
         impair any of such obligations, including without limitation:

         (a)     any time, waiver or indulgence granted to any person or the
                 forbearance of the Issuing Bank in enforcing the obligations
                 of any person under any Finance Document or in respect of any
                 other guarantee, security, obligation, right or remedy;

         (b)     the recovery of any judgment against any person or any action
                 to enforce the same;

         (c)     the taking of any other security from any person or the
                 failure, refusal, or neglect to take, perfect or enforce, any
                 rights, remedies or securities from or against any person or
                 all or any part of the security constituted by any of the
                 Finance Documents;

         (d)     any alteration in the constitution of any Obligor or any
                 defect in or irregular exercise of the borrowing or other
                 powers of any person or any legal limitation, disability,
                 incapacity or other
<PAGE>   127
                                    - 126 -



                 circumstance relating to any person or any legal limitation,
                 disability, incapacity or other circumstance relating to any
                 person whether arising in relation to any Finance Document or
                 otherwise howsoever;

         (e)     subject to clause 22.4 and 22.5 (Unanimous consents), any
                 amendment or supplement to or variation of any L/C Related
                 Document or any other Finance Document;

         (f)     the insolvency, bankruptcy, liquidation, reconstruction or
                 reorganization of, or analogous proceedings relating to any
                 person or any composition or arrangement made by any of them
                 with the Issuing Bank, any Bank or any other person or any
                 transfer or extinction of any liabilities of any Obligor by
                 any law, order regulation, decree, court order or similar
                 instrument;

         (g)     any irregularity, unenforceability or invalidity of any
                 obligations of any person under any security or document (to
                 the intent that such Bank's obligations under clause 4.7 shall
                 remain in full force as if there were no such irregularity,
                 unenforceability or invalidity);

         (h)     the occurrence of an Event of Default;

         (i)     the existence of any claim, set-off defence or other right
                 which any Obligor may have against any beneficiary of any
                 Letter of Credit or any other person; or

         (j)     any draft, certificate or any other document presented under
                 any Letter of Credit proving to be forged, fraudulent, invalid
                 or insufficient in any respect or any statement therein being
                 untrue or inaccurate in any respect.

5.       The Issuing Bank shall be entitled to enforce the obligations of each
         Bank under clause 4.7 without making any demand on or taking any
         proceedings against or filing any proof of claim in any insolvency,
         winding up, dissolution or liquidation of any person or exhausting any
         right or remedy against any person or taking any action to enforce any
         part of the security constituted or evidenced by any of the Finance
         Documents.

6.       The obligations of each Bank under clause 4.7 shall be continuing
         obligations and shall extend to the ultimate balance of the
         obligations referred to therein.  If, for any reason, such obligations
         cease to be continuing obligations, the Issuing Bank may open a new
         account with or continue any existing account with any person and the
         liability of each Bank in respect of amounts guaranteed by it pursuant
         to clause 4.7 at the date of such cessation shall remain regardless of
         any payments in or out of any such account.

7.       The Issuing Bank's rights under clause 4.7 shall be in addition to and
         shall be in no way prejudiced by any other rights of or security held
         by the Issuing Bank in relation to the obligations of any Obligor.
         The Issuing Bank's rights under clause 4.7 are in addition to and are
         not exclusive of those provided by law.

8.       A certificate of the Issuing Bank as to any amount due to it from any
         Bank pursuant to clause 4.7 shall be conclusive (in the absence of
         manifest error).

         amending the amount on the cover page to be L.3,625,000,000 and as
         follows:

         (a)     Clause 1.1(a)  (Purpose) of the Facilities Agreement is
                 amended by deleting "L.1,700,000,000" and inserting
                 "L.1,775,000,000" and by deleting "L.1,115,000,000" and
                 inserting "L.1,150,000,000";

         (b)     Clause 2.1(a) ("The Facilities") of the Facilities Agreement
                 is amended by deleting "L.1,700,000,000" and inserting
                 "L.1,775,000,000";

         (c)     Clause 2.1(b) (The Facilities) of the Facilities Agreement is
                 amended by deleting "L.1,115,000,000" and inserting
                 "L.1,150,000,000";

         (d)     Paragraph (c)(i) of Part B of Schedule 3 (Conditions
                 Precedent) of the Facilities Agreement is amended by deleting
                 "L.1,622,390,000" and inserting "L.1,678,082,000";

         (e)     Paragraph (f) and (k) of Part A of Schedule 3 (Conditions
                 Precedent) of the Facilities agreement are deleted and
                 inserted in Part B of Schedule 3 as new paragraphs (h) and (i)
                 respectively.  It is expressly recognized that whilst these
                 conditions precedent have not been satisfied as at the date of
                 this Agreement, the documents necessary to satisfy these
                 conditions are in agreed form subject only to the Debenture
                 being amended to refer to the Facilities as they are finally
                 amended in order to implement the Offer and to receiving the
                 advice of King & Spalding in respect of the perfection of the
                 security interest created by the Debenture over American
                 Depository Receipts;

         (f)     The definition of "Agreed Projections" in Clause 1.2
                 (Definitions) of the Facilities Agreement shall be amended to
                 read "means the projections for the Group dated 2nd March 1998
                 as amended by the supplemental projections of 3rd March 1998,
                 both in the agreed form";

         (g)     It is recognized that whilst the Loan Note Instrument referred
                 to in paragraph (e) of Part A of Schedule 3 (Conditions
                 Precedent) is in agreed form, it has not yet been executed; a
                 reference to the Loan Note Instrument, duly executed, will be
                 added to the new paragraph (h) of Part B of Schedule 3
                 referred to above;

         (h)     The definition of "Fee Letters" in Clause 1.2 (Definitions) of
                 Facilities Agreement shall be construed as including, without
                 limitation, the fee letter referred to in Clause 7.1(a) of the
                 Facilities Agreement, as amended and restated on 3 March 1998;
                 and

             (the "AGREEMENT"), dated as of March 6, 1998, among TEXAS
             UTILITIES COMPANY, a Texas corporation (the "BORROWER"); the
             lenders listed in Schedule 2.01 (together with their
             successors and assigns, the "LENDERS"); THE CHASE MANHATTAN
             BANK ("CHASE"), as Competitive Advance Facility Agent (in such
             capacity, the "CAF AGENT"); and CHASE BANK OF TEXAS, NATIONAL

             for the Lenders (in such capacity, the "ADMINISTRATIVE AGENT";

         The Borrower has requested the Lenders to extend credit in the form of
Standby Borrowings (such term and each other capitalized term used herein
having the meaning given it in Article I) to the Borrower in an aggregate
principal amount at any time outstanding not in excess of $900,000,000.  The
Borrower has also requested the Lenders to provide a procedure pursuant to
which the Borrower may invite the Lenders to bid on an uncommitted basis on
short-term borrowings by the Borrower.  Subject to the terms and conditions set
forth herein, the proceeds of any such borrowings are to be used to finance or
refinance (directly or indirectly, including as a commercial paper back-up)
equity or subordinated loan advances from the Borrower to FinCo 1 and FinCo 2
in connection with the Acquisition.  The Lenders are willing to extend such
credit to the Borrower on the terms and subject to the conditions herein set
forth.

         Accordingly, the parties hereto agree as follows:

         is not so released for any day which is a Business Day, the arithmetic

         Chase, of the quotations for the day of such transactions received by
         Chase from three Federal funds brokers of recognized standing selected
         by it.  If for any reason Chase shall have determined (which
         determination shall be conclusive absent manifest error; provided that
         Chase, shall, upon request, provide to the Borrower a certificate
         setting forth in reasonable detail the basis for such determination)

context shall otherwise require.  Except as otherwise expressly provided
herein, all terms of an accounting or financial nature shall be construed in

                                   ARTICLE II
                                  THE CREDITS

         SECTION 2.01.  COMMITMENTS.  Subject to the terms and conditions and
relying upon the representations and warranties herein set forth, each Lender
agrees, severally and not jointly, to make Standby Loans, at any time and from
time to time until the earlier of the Maturity Date and the termination of the
Commitment of such Lender, to the Borrower in an aggregate principal amount at
any time outstanding not to exceed such Lender's Commitment minus the amount by
which the Competitive Loans made to the Borrower and outstanding at such time
shall be deemed to have used such Commitment pursuant to Section 2.14, subject,
however, to the conditions that (i) at no time shall the sum of (x) the
outstanding aggregate principal amount of all Standby Loans plus (y) the
outstanding aggregate principal amount of all Competitive Loans exceed the
Total Commitment, (ii) Loans shall be made in no more than ten Borrowings that
would, after giving effect to any such Borrowing, increase the principal amount
of Loans outstanding, (iii) at no time shall the sum of (x) the outstanding
aggregate principal amount of Loans hereunder plus (y) the outstanding
aggregate principal amount of all other Indebtedness of the Borrower used for
purposes described in Section 5.08 exceed $2,000,000,000, (iv) at no time shall
the outstanding aggregate principal amount of all Standby Loans made by any
Lender exceed the amount of such Lender's Commitment and (v) at all times, the
outstanding aggregate principal amount of all Standby Loans made by each Lender
to the Borrower shall equal the product of (A) the percentage which such
Lender's Commitment represents of the Total Commitment times (B) the
outstanding aggregate principal amount of all Standby Loans made to the
Borrower.

         Within the foregoing limits, the Borrowers may borrow, pay or prepay
and, subject to the limitations set forth in Section 2.11(a), reborrow Standby
Loans hereunder, on and after the Effective Date and prior to the Maturity
Date, subject to the terms, conditions and limitations set forth herein.

         SECTION 2.02.  LOANS.  (a)  Each Standby Loan shall be made as part of
a Borrowing consisting of Loans made by the Lenders ratably in accordance with
their respective Commitments; provided, however, that the failure of any Lender
to make any Standby Loan shall not in itself relieve any other Lender of its
obligation to lend hereunder (it being understood, however, that no Lender
shall be responsible for the failure of any other Lender to make any Loan
required to be made by such other Lender).  Each Competitive Loan shall be made
in accordance with the





                                INTERIM FACILITY
<PAGE>   22
procedures set forth in Section 2.03.  The Standby Loans or Competitive Loans
comprising any Borrowing shall be (i) in the case of Competitive Loans, in an
aggregate principal amount which is an integral multiple of $1,000,000 and not
less than $5,000,000 and (ii) in the case of Standby Loans, in an aggregate
principal amount which is an integral multiple of $5,000,000 and not less than
$25,000,000 (or an aggregate principal amount equal to the remaining balance of
the available Commitments).

         (b)     Each Competitive Borrowing shall be comprised entirely of
Eurodollar Competitive Loans or Fixed Rate Loans, and each Standby Borrowing
shall be comprised entirely of Eurodollar Standby Loans or ABR Loans, as the
Borrower may request pursuant to Section 2.03 or 2.04, as applicable. Each
Lender may at its option make any Eurodollar Loan by causing any domestic or
foreign branch or Affiliate of such Lender to make such Loan; provided that any
exercise of such option shall not affect the obligation of the Borrower to
repay such Loan in accordance with the terms of this Agreement.  Borrowings of
more than one Type may be outstanding at the same time.

         (c)     Subject to paragraph (d) below, each Lender shall make each
Loan to be made by it hereunder on the proposed date thereof by wire transfer
of immediately available funds to the Administrative Agent in Houston, Texas,
not later than noon, Houston time, and the Administrative Agent shall by 2:00
p.m., Houston time, credit the amounts so received to the account or accounts
specified from time to time in one or more notices delivered by the Borrower to
the Administrative Agent or, if a Borrowing shall not occur on such date
because any condition precedent herein specified shall not have been met,
return the amounts so received to the respective Lenders.  Competitive Loans
shall be made by the Lender or Lenders whose Competitive Bids therefor are
accepted pursuant to Section 2.03 in the amounts so accepted.  Standby Loans
shall be made by the Lenders pro rata in accordance with Section 2.14.  Unless
the Administrative Agent shall have received notice from a Lender prior to the
date of any Borrowing that such Lender will not make available to the
Administrative Agent such Lender's portion of such Borrowing, the
Administrative Agent may assume that such Lender has made such portion
available to the Administrative Agent on the date of such Borrowing in
accordance with this paragraph (c) and the Administrative Agent may, in
reliance upon such assumption, make available to the Borrower on such date a
corresponding amount.  If and to the extent that such Lender shall not have
made such portion available to the Administrative Agent, such Lender and the
Borrower (without waiving any claim against such Lender for such Lender's
failure to make such portion available) severally agree to repay to the
Administrative Agent forthwith on demand such corresponding amount together
with interest thereon, for each day from the date such amount is made available
to the Borrower until the date such amount is repaid to the Administrative
Agent at (i) in the case of the Borrower, the interest rate applicable at the
time to the Loans comprising such Borrowing and (ii) in the case of such
Lender, the Federal Funds Effective Rate.  If such Lender shall repay to the
Administrative Agent such corresponding amount, such amount shall constitute
such Lender's Loan as part of such Borrowing for purposes of this Agreement.

         (d)     The Borrower may refinance all or any part of any Standby
Borrowing with a Standby Borrowing of the same or a different Type, subject to
the conditions and limitations set forth in this Agreement.  Any Standby
Borrowing or part thereof so refinanced shall be deemed to be repaid or prepaid
in accordance with Section 2.06 or 2.11, as applicable, with the proceeds of a
new Standby Borrowing, and the proceeds of the new Standby Borrowing, to the
extent they do not exceed the principal amount of the Standby Borrowing being
refinanced, shall not be paid by the Lenders to the Administrative Agent or by
the Administrative Agent to the Borrower pursuant to paragraph (c) above.

         SECTION 2.03.  COMPETITIVE BID PROCEDURE.  (a)  In order to request
Competitive Bids, the Borrower shall hand deliver or telecopy to the CAF Agent
a duly completed Competitive Bid Request in the form of Exhibit A-1 hereto, to
be received by the CAF Agent (i) in the case of a Eurodollar Competitive
Borrowing, not later than 11:00 a.m., New York City time, four Business Days
before a proposed Competitive Borrowing and (ii) in the case of a Fixed Rate
Borrowing, not later than 11:00 a.m., New York City time, one Business Day
before a proposed Competitive Borrowing.  No ABR Loan shall be requested in, or
made pursuant to, a Competitive Bid Request.  A Competitive Bid Request that
does not conform substantially to the format of Exhibit A-1 may be rejected in
the CAF Agent's sole discretion, and the CAF Agent shall promptly notify the
Borrower of such rejection by telecopy.  Each Competitive Bid Request shall
refer to this Agreement and specify (x) whether the Borrowing then being
requested is to be a Eurodollar Borrowing or a Fixed Rate Borrowing, (y) the
date of such Borrowing (which shall be a Business Day) and the aggregate
principal amount thereof which shall be in a minimum principal amount of
$5,000,000 and in an integral multiple of $1,000,000, and (z) the Interest
Period with respect thereto (which may not end after the Maturity Date).
Promptly after its receipt of a Competitive Bid Request that is not rejected as
aforesaid, the CAF Agent shall telecopy to each Lender a Notice of Competitive
Bid Request in the form of Exhibit A-2 inviting the Lenders to bid, on the
terms and conditions of this Agreement, to make Competitive Loans.

         (b)     Each Lender invited to bid may, in its sole discretion, make
one or more Competitive Bids to the Borrower responsive to the Borrower's
Competitive Bid Request.  Each Competitive Bid by a Lender must be received by
the CAF Agent by telecopy, in the form of Exhibit A-3 hereto, (i) in the case
of a Eurodollar Competitive Borrowing, not later than 9:30 a.m., New York City
time, three Business Days before a proposed Competitive Borrowing and (ii) in
the case of a Fixed Rate Borrowing, not later than 9:30 a.m., New York City
time, on the day of a proposed Competitive Borrowing.  Multiple bids will be
accepted by the CAF Agent.  Competitive Bids that do not conform substantially
to the format of Exhibit A-3 may be rejected by the CAF Agent, and the CAF
Agent shall notify the Lender making such nonconforming bid of such rejection
as soon as practicable.  Each Competitive Bid shall refer to this Agreement and
specify (x) the principal amount (which shall be in a minimum principal amount
of $5,000,000 and in an integral multiple of $1,000,000 and which may equal the
entire principal amount of the Competitive Borrowing requested by the Borrower)
of the Competitive Loan or Loans that the Lender is willing to make to the
Borrower, (y) the Competitive Bid Rate or Rates at which the





                                INTERIM FACILITY
<PAGE>   24
Lender is prepared to make the Competitive Loan or Loans and (z) the Interest
Period and the last day thereof.  If any Lender invited to bid shall elect not
to make a Competitive Bid, such Lender shall so notify the CAF Agent by
telecopy (I) in the case of Eurodollar Competitive Loans, not later than 9:30
a.m., New York City time, three Business Days before a proposed Competitive
Borrowing, and (II) in the case of Fixed Rate Loans, not later than 9:30 a.m.,
New York City time, on the day of a proposed Competitive Borrowing; provided,
however, that failure by any Lender to give such notice shall not cause such
Lender to be obligated to make any Competitive Loan as part of such Competitive
Borrowing.  A Competitive Bid submitted by a Lender pursuant to this paragraph
(b) shall be irrevocable.

         (c)     The CAF Agent shall notify the Borrower by telecopy, of all
the Competitive Bids made, the Competitive Bid Rate and the principal amount of
each Competitive Loan in respect of which such Competitive Bid was made and the
identity of the Lender that made each such bid by (i) in the case of a
Eurodollar Competitive Borrowing, not later than 10:00 a.m., New York City
time, three Business Days before a proposed Competitive Borrowing and (ii) in
the case of a Fixed Rate Borrowing, not later than 10:00 a.m., New York City
time, on the day of a proposed Competitive Borrowing.  The CAF Agent shall send
a copy of all Competitive Bids to the Borrower for its records as soon as
practicable after the completion of the bidding process set forth in this
Section 2.03.

         (d)     The Borrower may in its sole and absolute discretion, subject
only to the provisions of this paragraph (d), accept or reject any or all
Competitive Bids referred to in paragraph (c) above.  The Borrower shall notify
the CAF Agent by telephone, confirmed by telecopy in the form of a Competitive
Bid Accept/Reject Letter, whether and to what extent it has decided to accept
or reject any of or all the bids referred to in paragraph (c) above by (i) in
the case of a Eurodollar Competitive Borrowing, not later than 10:30 a.m., New
York City time, three Business Days before a proposed Competitive Borrowing and
(ii) in the case of a Fixed Rate Borrowing, not later than 10:30 a.m., New York
City time, on the day of a proposed Competitive Borrowing; provided, however,
that (i) the failure by the Borrower to give such notice shall be deemed to be
a rejection of all the bids referred to in paragraph (c) above, (ii) the
Borrower shall not accept a bid made at a particular Competitive Bid Rate if it
has decided to reject a bid made at a lower Competitive Bid Rate, (iii) the
aggregate amount of the Competitive Bids accepted by the Borrower shall not
exceed the principal amount specified in the Competitive Bid Request, (iv) if
the Borrower shall accept a bid or bids made at a particular Competitive Bid
Rate but the amount of such bid or bids shall cause the total amount of bids to
be accepted by the Borrower to exceed the amount specified in the Competitive
Bid Request, then the Borrower shall accept a portion of such bid or bids in an
amount equal to the amount specified in the Competitive Bid Request less the
amount of all other Competitive Bids accepted with respect to such Competitive
Bid Request, which acceptance, in the case of multiple bids at such Competitive
Bid Rate, shall be made pro rata in accordance with the amount of each such bid
at such Competitive Bid Rate, and (v) except pursuant to clause (iv) above, no
bid shall be accepted for a Competitive Loan unless such Competitive Loan is in
a minimum principal amount of $5,000,000 and an integral multiple





                                INTERIM FACILITY
<PAGE>   25
of $1,000,000; provided further, however, that if a Competitive Loan must be in
an amount less than $5,000,000 because of the provisions of clause (iv) above,
such Competitive Loan may be for a minimum of $1,000,000 or any integral
multiple thereof, and in calculating the pro rata allocation of acceptances of
portions of multiple bids at a particular Competitive Bid Rate pursuant to
clause (iv) the amounts shall be rounded to integral multiples of $1,000,000 in
a manner which shall be in the discretion of the Borrower.  A notice given by
the Borrower pursuant to this paragraph (d) shall be irrevocable.

         (e)     The CAF Agent shall promptly notify each bidding Lender (and
the Administrative Agent), by telecopy, whether or not its Competitive Bid has
been accepted (and if so, in what amount and at what Competitive Bid Rate) and
each successful bidder will thereupon become bound, subject to the other
applicable conditions hereof, to make the Competitive Loan in respect of which
its bid has been accepted.

         (f)     No Competitive Borrowing shall be requested or made hereunder
if after giving effect thereto any of the conditions set forth in clauses (i)
through (iv) of Section 2.01 would not be met.

         (g)     If either the Administrative Agent or CAF Agent shall elect to
submit a Competitive Bid in its capacity as a Lender, such party shall submit
such bid directly to the Borrower one quarter of an hour earlier than the
latest time at which the other Lenders are required to submit their bids to the
CAF Agent pursuant to paragraph (b) above.

         (h)     Each of the Borrower and the CAF Agent shall deliver to the
Administrative Agent by telecopy copies of all notices delivered by it pursuant
to this Section 2.03 at the same times such notices are delivered hereunder.
All notices required by this Section 2.03 shall be given in accordance with
Section 8.01.

         (i)     A Competitive Bid Request shall not be made within five
Business Days after the date of any previous Competitive Bid which was accepted
by the Borrower pursuant to paragraph (d) above.

         SECTION 2.04.  STANDBY BORROWING PROCEDURE.  In order to request a
Standby Borrowing, the Borrower shall hand deliver or telecopy to the
Administrative Agent a duly completed Standby Borrowing Request in the form of
Exhibit A-5 (a) in the case of a Eurodollar Standby Borrowing, not later than
10:00 a.m., Houston time, three Business Days before such Borrowing, and (b) in
the case of an ABR Borrowing, not later than 10:00 a.m., Houston time, one
Business Day before such Borrowing.  No Fixed Rate Loan shall be requested or
made pursuant to a Standby Borrowing Request.  Such notice shall be irrevocable
and shall in each case specify (i) whether the Borrowing then being requested
is to be a Eurodollar Standby Borrowing or an ABR Borrowing; (ii) the date of
such Standby Borrowing (which shall be a Business Day) and the amount thereof;
and (iii) if such Borrowing is to be a Eurodollar Standby Borrowing, the





                                INTERIM FACILITY
<PAGE>   26
Interest Period with respect thereto, which shall not end after the Maturity
Date.  If no election as to the Type of Standby Borrowing is specified in any
such notice, then the requested Standby Borrowing shall be an ABR Borrowing.
If no Interest Period with respect to any Eurodollar Standby Borrowing is
specified in any such notice, then the Borrower shall be deemed to have
selected an Interest Period of one month's duration (subject, at all times
prior to completion of syndication of the Total Commitment, to the limitations
set forth in the definition of "Interest Period").  If the Borrower shall not
have given notice in accordance with this Section 2.04 of its election to
refinance a Standby Borrowing prior to the end of the Interest Period in effect
for such Borrowing, then the Borrower shall (unless such Borrowing is repaid at
the end of such Interest Period) be deemed to have given notice of an election
to refinance such Borrowing with an ABR Borrowing.  Notwithstanding any other
provision of this Agreement to the contrary, no Standby Borrowing shall be
requested if the Interest Period with respect thereto would end after the
Maturity Date.  The Administrative Agent shall promptly advise the Lenders of
any notice given pursuant to this Section 2.04 and of each Lender's portion of
the requested Borrowing.

         SECTION 2.05.  FEES.  (a) The Borrower agrees to pay to each Lender,
through the Administrative Agent, on each March 31, June 30, September 30 and
December 31 (with the first payment being due on March 31, 1998) and on each
date on which the Commitment of such Lender shall be terminated as provided
herein, a facility fee (a "FACILITY FEE"), at a rate per annum equal to the
Facility Fee Percentage from time to time in effect on the amount of the sum of
the unused Commitment of such Lender plus the principal amount of Loans
outstanding made by such Lender (without regard, in either case, to any
Competitive Loans made by any Lender), during the preceding quarter (or other
period commencing on the Effective Date or ending with the Maturity Date or any
date on which the Commitment of such Lender shall be terminated).  All Facility
Fees shall be computed on the basis of the actual number of days elapsed in a
year of 365 or 366 days, as the case may be.  The Facility Fee due to each
Lender shall commence to accrue on the Effective Date, and shall cease to
accrue on the earlier of the Maturity Date and the termination of the
Commitment of such Lender as provided herein.

         (b)     The Borrower agrees to pay the CAF Agent, for its own account,
the Auction Fees  provided for in the Agent Fee Letter referred to in the
Letter Agreement.

         (c)     All Fees shall be paid on the dates due, in immediately
available funds, to the Administrative Agent for distribution, if and as
appropriate, among the Lenders, the Initial Underwriters or the Joint Lead
Arrangers or to the CAF Agent.  Once paid, none of the Fees shall be refundable
under any circumstances.

         SECTION 2.06.  REPAYMENT OF LOANS; EVIDENCE OF INDEBTEDNESS.  (a)  The
outstanding principal balance of each Loan shall be due and payable on the last
day of the Interest Period applicable thereto and on the Maturity Date.





                                INTERIM FACILITY
<PAGE>   27
         (b)     Each Lender shall maintain in accordance with its usual
practice an account or accounts evidencing the indebtedness to such Lender
resulting from each Loan made by such Lender from time to time, including the
amounts of principal and interest payable and paid to such Lender from time to
time under this Agreement.

         (c)     The Administrative Agent shall maintain accounts in which it
will record (i) the amount of each Loan made hereunder, the Type of each Loan
made and the Interest Period applicable thereto, (ii) the amount of any
principal or interest due and payable or to become due and payable from the
Borrower to each Lender hereunder and (iii) the amount of any sum received by
the Administrative Agent hereunder from the Borrower and each Lender's share
thereof.

         (d)     The entries made in the accounts maintained pursuant to
paragraphs (b) and (c) of this Section 2.06 shall, to the extent permitted by
applicable law, be prima facie evidence of the existence and amounts of the
obligations therein recorded; provided, however, that the failure of any Lender
or the Administrative Agent to maintain such accounts or any error therein
shall not in any manner affect the obligations of the Borrower to repay the
Loans in accordance with their terms.

         SECTION 2.07.  INTEREST ON LOANS.  (a)  Subject to the provisions of
Section 2.08, the Loans comprising each Eurodollar Borrowing shall bear
interest (computed on the basis of the actual number of days elapsed over a
year of 360 days) at a rate per annum equal to the LIBO Rate for the Interest
Period in effect for such Borrowing plus the Applicable Margin from time to
time in effect and in the case of each Eurodollar Competitive Loan, the LIBO
Rate for the Interest Period in effect for such Borrowing plus the Competitive
Bid Margin offered by the Lender making such Loan and accepted by the Borrower
pursuant to Section 2.03.

         (b)     Subject to the provisions of Section 2.08, the Loans
comprising each ABR Borrowing shall bear interest (computed on the basis of the
actual number of days elapsed over a year of 365 or 366 days, as the case may
be, for periods during which the Alternate Base Rate is determined by reference
to the Prime Rate and 360 days for other periods) at a rate per annum equal to
the Alternate Base Rate plus the Applicable Margin from time to time in effect.

         (c)     Subject to the provisions of Section 2.08, each Fixed Rate
Loan shall bear interest at a rate per annum (computed on the basis of the
actual number of days elapsed over a year of 360 days) equal to the fixed rate
of interest offered by the Lender making such Loan and accepted by the Borrower
pursuant to Section 2.03.

         (d)     Interest on each Loan shall be payable on each Interest
Payment Date applicable to such Loan except as otherwise provided in this
Agreement.  The applicable LIBO Rate or Alternate Base Rate for each Interest
Period or day within an Interest Period, as the case may be, shall be
determined by Chase, and such determination shall be conclusive absent manifest
error;





                                INTERIM FACILITY
<PAGE>   28
provided that Chase shall, upon request, provide to the Borrower a certificate
setting forth in reasonable detail the basis for such determination.

         SECTION 2.08.  DEFAULT INTEREST.  If the Borrower shall default in the
payment of the principal of or interest on any Loan or any other amount
becoming due hereunder, whether by scheduled maturity, notice of prepayment,
acceleration or otherwise, the Borrower shall on demand from time to time from
the Administrative Agents pay interest, to the extent permitted by law, on such
defaulted amount up to (but not including) the date of actual payment (after as
well as before judgment) at a rate per annum (computed as provided in Section
2.07(b)) equal to the Alternate Base Rate plus the Applicable Margin for ABR
Loans plus 1%.

         SECTION 2.09.  ALTERNATE RATE OF INTEREST.  In the event, and on each
occasion, that on the day two Business Days prior to the commencement of any
Interest Period for a Eurodollar Borrowing the Administrative Agent shall have
determined (i) that dollar deposits in the principal amounts of the Eurodollar
Loans comprising such Borrowing are not generally available in the London
interbank market or (ii) that reasonable means do not exist for ascertaining
the LIBO Rate, the Administrative Agent shall, as soon as practicable
thereafter, give telecopy notice of such determination to the Borrower and the
Lenders.  In the event of any such determination under clauses (i) or (ii)
above, until the Administrative Agent shall have advised the Borrower and the
Lenders that the circumstances giving rise to such notice no longer exist, (x)
any request by the Borrower for a Eurodollar Competitive Borrowing pursuant to
Section 2.03 shall be of no force and effect and shall be denied by the
Administrative Agent and (y) any request by the Borrower for a Eurodollar
Standby Borrowing pursuant to Section 2.04 shall be deemed to be a request for
an ABR Borrowing.  In the event the Required Lenders notify the Administrative
Agent that the rates at which dollar deposits are being offered will not
adequately and fairly reflect the cost to such Lenders of making or maintaining
Eurodollar Loans during such Interest Period, the Administrative Agent shall
notify the Borrower of such notice and until the Required Lenders shall have
advised the Administrative Agent that the circumstances giving rise to such
notice no longer exist, any request by the Borrower for a Eurodollar Standby
Borrowing shall be deemed a request for an ABR Borrowing.  Each determination
by the Administrative Agent hereunder shall be made in good faith and shall be
conclusive absent manifest error; provided that the Administrative Agent,
shall, upon request, provide to the Borrower a certificate setting forth in
reasonable detail the basis for such determination.

         SECTION 2.10.  TERMINATION AND REDUCTION OF COMMITMENTS.  (a)  The
Commitments shall be automatically terminated on the earliest to occur of (i)
Maturity Date, (ii) the date of the withdrawal or lapse of the Offer and (iii)
28 days after the Effective Date if the Offer has not yet been posted.

         (b)     In addition, the Commitments shall be automatically reduced by
an amount equal to the net proceeds of any issuance or disposition or any
payment to the Borrower, in each case, described in Section 2.11(d), with such
reduction to be effective on the later to occur of the date





                                INTERIM FACILITY
<PAGE>   29
of such issuance, disposition or payment, as the case may be, and the date
specified under Section 2.11(d) for any related prepayment or repayment of the
Loans.

         (c)     Upon at least two Business Days' prior irrevocable written
notice to the Administrative Agent, the Borrower may at any time in whole
permanently terminate, or from time to time in part permanently reduce, the
Commitments; provided, however, that (i) each partial reduction of the
Commitments shall be in an integral multiple of $10,000,000 and in a minimum
principal amount of $10,000,000 and (ii) no such termination or reduction shall
be made that would reduce the Total Commitment to an amount (1) less than the
aggregate outstanding principal amount of all Competitive Loans or (2) less
than $50,000,000, unless the result of such termination or reduction referred
to in this clause (2) is to reduce the Total Commitment to $0.  The
Administrative Agent shall advise the Lenders of any notice given pursuant to
this Section 2.10(c) and of each Lender's portion of any such termination or
reduction of the Total Commitment.

         (d)     Each reduction in the Total Commitment hereunder shall be made
ratably among the Lenders in accordance with their respective Commitments.  The
Borrower shall pay to the Administrative Agent for the account of the Lenders,
on the date of each termination or reduction of the Total Commitment, the
Facility Fees on the amount of the Commitments so terminated or reduced accrued
through the date of such termination or reduction.

         SECTION 2.11.  PREPAYMENT.  (a)  The Borrower shall have the right at
any time and from time to time to prepay any Standby Borrowing, in whole or in
part, upon giving telecopy notice (or telephone notice promptly confirmed by
telecopy) to the Administrative Agent:  (i) before 10:00 a.m., Houston time,
three Business Days prior to prepayment, in the case of Eurodollar Loans, and
(ii) before 10:00 a.m., Houston time, one Business Day prior to prepayment, in
the case of ABR Loans; provided, however, that each partial prepayment shall be
in an amount which is an integral multiple of $10,000,000 and not less than
$10,000,000.  No prepayment may be made in respect of any Competitive
Borrowing.  Any principal amount of any Loan repaid or prepaid at any time and
not refinanced on the date of such repayment or prepayment (as the case may be)
with the proceeds of another Loan may not be reborrowed.

         (b)     On the date of any termination or reduction of the Commitments
pursuant to Section 2.10, the Borrower shall pay or prepay so much of the
Standby Borrowings as shall be necessary in order that the aggregate principal
amount of the Competitive Loans and Standby Loans outstanding will not exceed
the Total Commitment, after giving effect to such termination or reduction.

         (c)     Each notice of prepayment shall specify the prepayment date
and the principal amount of each Borrowing (or portion thereof) to be prepaid,
shall be irrevocable and shall commit the Borrower to prepay such Borrowing (or
portion thereof) by the amount stated therein on the date stated therein.  All
prepayments under this Section 2.11 shall be subject to Section 8.05 but





                                INTERIM FACILITY
<PAGE>   30
otherwise without premium or penalty.  All prepayments under this Section 2.11
shall be accompanied by accrued interest on the principal amount being prepaid
to the date of payment.

         (d)     Upon (i) the issuance by the Borrower (or any special purpose
financing Subsidiary of the Borrower, other than FinCo 1, FinCo 2 or any
Subsidiary of FinCo 1 or of FinCo 2) of any debt, equity or other capital
market instruments or other securities (other than stock of the Borrower issued
in connection with employee stock option and other stock purchase and incentive
plans in effect on the date hereof), (ii) the disposition by the Borrower of
any of the capital shares of FinCo 1, FinCo 2 or Enserch, or (iii) the payment
by any Acquisition Company to the Borrower of any amount in respect of shares
of the Borrower exchanged for Target Shares, the Borrower shall prepay the
principal amount of Loans hereunder in an amount equal to the net proceeds of
such issuance or disposition or such payment, as the case may be, with such
prepayment to be accompanied by payment of accrued interest on such Loans being
prepaid to the date of payment and any amounts payable pursuant to Section
8.05.  Any amounts required to be applied to the prepayment of Loans shall be
applied as follows:  first, to the immediate prepayment of ABR Loans
outstanding, second, to the prepayment of Eurodollar Loans (not constituting
Competitive Loans) outstanding on the last day of the respective Interest
Periods for such Eurodollar Loans in the order that they occur, and third, to
the repayment of Competitive Loans, on the last day of the respective Interest
Periods for such Competitive Loans in the order that they occur.

         SECTION 2.12.  RESERVE REQUIREMENTS; CHANGE IN CIRCUMSTANCES.  (a)
Notwithstanding any other provision herein, if after the date of this Agreement
any change in applicable law or regulation or in the interpretation or
administration thereof by any Governmental Authority charged with the
interpretation or administration thereof (whether or not having the force of
law) shall change the basis of taxation of payments to any Lender hereunder
(except for changes in respect of taxes on the overall net income of such
Lender or its lending office imposed by the jurisdiction in which such Lender's
principal executive office or lending office is located), or shall result in
the imposition, modification or applicability of any reserve, special deposit
or similar requirement against assets of, deposits with or for the account of
or credit extended by any Lender, or shall result in the imposition on any
Lender or the London interbank market of any other condition affecting this
Agreement, such Lender's Commitment or any Eurodollar Loan or Fixed Rate Loan
made by such Lender, and the result of any of the foregoing shall be to
increase the cost to such Lender of making or maintaining any Eurodollar Loan
or Fixed Rate Loan or to reduce the amount of any sum received or receivable by
such Lender hereunder (whether of principal, interest or otherwise) by an
amount deemed by such Lender to be material, then the Borrower shall, upon
receipt of the notice and certificate provided for in Section 2.12(c), promptly
pay to such Lender such additional amount or amounts as will compensate such
Lender for such additional costs incurred or reduction suffered.
Notwithstanding the foregoing, no Lender shall be entitled to request
compensation under this paragraph with respect to any Competitive Loan if





                                INTERIM FACILITY
<PAGE>   31
the change giving rise to such request was applicable to such Lender at the
time of submission of the Competitive Bid pursuant to which such Competitive
Loan was made.

         (b)     If any Lender shall have determined that the adoption of any
law, rule, regulation or guideline arising out of the July 1988 report of the
Basle Committee on Banking Regulations and Supervisory Practices entitled
"International Convergence of Capital Measurement and Capital Standards," or
the adoption after the date hereof of any other law, rule, regulation or
guideline regarding capital adequacy, or any change in any of the foregoing or
in the interpretation or administration of any of the foregoing by any
Governmental Authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by any Lender (or any
lending office of such Lender) or any Lender's holding company with any request
or directive regarding capital adequacy (whether or not having the force of
law) of any such authority, central bank or comparable agency, has or would
have the effect of reducing the rate of return on such Lender's capital or on
the capital of such Lender's holding company, if any, as a consequence of this
Agreement, such Lender's Commitment or the Loans made by such Lender pursuant
hereto to a level below that which such Lender or such Lender's holding company
could have achieved but for such adoption, change or compliance (taking into
consideration such Lender's policies and the policies of such Lender's holding
company with respect to capital adequacy) by an amount deemed by such Lender to
be material, then from time to time such additional amount or amounts as will
compensate such Lender for any such reduction suffered will be paid by the
Borrower to such Lender.  It is acknowledged that this Agreement is being
entered into by the Lenders on the understanding that the Lenders will not be
required to maintain capital against their Commitments under currently
applicable laws, regulations and regulatory guidelines.  In the event the
Lenders shall otherwise determine that such understanding is incorrect, it is
agreed that the Lenders will be entitled to make claims under this paragraph
(b) based upon market requirements prevailing on the date hereof for
commitments under comparable credit facilities against which capital is
required to be maintained.

         (c)     A certificate of each Lender setting forth such amount or
amounts as shall be necessary to compensate such Lender or its holding company
as specified in paragraph (a) or (b) above, as the case may be, and containing
an explanation in reasonable detail of the manner in which such amount or
amounts shall have been determined, shall be delivered to the Borrower and
shall be conclusive absent manifest error.  The Borrower shall pay each Lender
the amount shown as due on any such certificate delivered by it within 10 days
after its receipt of the same.  Each Lender shall give prompt notice to the
Borrower of any event of which it has knowledge, occurring after the date
hereof, that it has determined will require compensation by the Borrower
pursuant to this Section; provided, however, that failure by such Lender to
give such notice shall not constitute a waiver of such Lender's right to demand
compensation hereunder.

         (d)     Failure on the part of any Lender to demand compensation for
any increased costs or reduction in amounts received or receivable or reduction
in return on capital with respect to any period shall not constitute a waiver
of such Lender's right to demand compensation with respect





                                INTERIM FACILITY
<PAGE>   32
to such period or any other period; provided, however, that no Lender shall be
entitled to compensation under this Section 2.12 for any costs incurred or
reductions suffered with respect to any date unless it shall have notified the
Borrower that it will demand compensation for such costs or reductions under
paragraph (c) above not more than 90 days after the later of (i) such date and
(ii) the date on which it shall have become aware of such costs or reductions.
The protection of this Section shall be available to each Lender regardless of
any possible contention of the invalidity or inapplicability of the law, rule,
regulation, guideline or other change or condition which shall have occurred or
been imposed.

         (e)     Each Lender agrees that it will designate a different lending
office if such designation will avoid the need for, or reduce the amount of,
such compensation and will not, in the reasonable judgment of such Lender, be
disadvantageous to such Lender.

         SECTION 2.13.  CHANGE IN LEGALITY.  (a)  Notwithstanding any other
provision herein, if any change in any law or regulation or in the
interpretation thereof by any Governmental Authority charged with the
administration or interpretation thereof shall make it unlawful for any Lender
to make or maintain any Eurodollar Loan or to give effect to its obligations as
contemplated hereby with respect to any Eurodollar Loan, then, by written
notice to the Borrower and to the Agents, such Lender may:

                 (i)      declare that Eurodollar Loans will not thereafter be
         made by such Lender hereunder, whereupon such Lender shall not submit
         a Competitive Bid in response to a request for Eurodollar Competitive
         Loans and any request for a Eurodollar Standby Borrowing shall, as to
         such Lender only, be deemed a request for an ABR Loan unless such
         declaration shall be subsequently withdrawn (any Lender delivering
         such a declaration hereby agreeing to withdraw such declaration
         promptly upon determining that such event of illegality no longer
         exists); and

                 (ii)     require that all outstanding Eurodollar Loans made by
         it be converted to ABR Loans, in which event all such Eurodollar Loans
         shall be automatically converted to ABR Loans as of the effective date
         of such notice as provided in paragraph (b) below.

In the event any Lender shall exercise its rights under (i) or (ii) above, all
payments and prepayments of principal which would otherwise have been applied
to repay the Eurodollar Loans that would have been made by such Lender or the
converted Eurodollar Loans of such Lender shall instead be applied to repay the
ABR Loans made by such Lender in lieu of, or resulting from the conversion of,
such Eurodollar Loans.

         (b)     For purposes of this Section 2.13, a notice by any Lender
shall be effective as to each Eurodollar Loan, if lawful, on the last day of
the Interest Period currently applicable to such Eurodollar Loan; in all other
cases such notice shall be effective on the date of receipt.

         SECTION 2.14.  PRO RATA TREATMENT.  Except as provided below in this
Section 2.14 with respect to Competitive Borrowings and as required under
Sections 2.13 and 2.18, each Standby Borrowing, each payment or prepayment of
principal of any Standby Borrowing, each payment of interest on the Standby
Loans, each payment of the Facility Fees, each reduction of the Commitments and
each refinancing or conversion of any Borrowing with a Standby Borrowing of any
Type, shall be allocated pro rata among the Lenders in accordance with their
respective Commitments (or, if such Commitments shall have expired or been
terminated, in accordance with the respective principal amounts of their
outstanding Standby Loans).  Each payment of principal of any Competitive
Borrowing shall be allocated pro rata among the Lenders participating in such
Borrowing in accordance with the respective principal amounts of their
outstanding Competitive Loans comprising such Borrowing.  Each payment of
interest on any Competitive Borrowing shall be allocated pro rata among the
Lenders participating in such Borrowing in accordance with the respective
amounts of accrued and unpaid interest on their outstanding Competitive Loans
comprising such Borrowing.  For purposes of determining the available
Commitments of the Lenders at any time, each outstanding Competitive Borrowing
shall be deemed to have utilized the Commitments of the Lenders (including
those Lenders which shall not have made Loans as part of such Competitive
Borrowing) pro rata in accordance with such respective Commitments.  Each
Lender agrees that in computing such Lender's portion of any Borrowing to be
made hereunder, the Administrative Agent may, in its discretion, round each
Lender's percentage of such Borrowing to the next higher or lower whole dollar
amount.

         SECTION 2.15.  SHARING OF SETOFFS.  Each Lender agrees that if it
shall, through the exercise of a right of banker's lien, setoff or
counterclaim, or pursuant to a secured claim under Section 506 of Title 11 of
the United States Code or other security or interest arising from, or in lieu
of, such secured claim, received by such Lender under any applicable
bankruptcy, insolvency or other similar law or otherwise, or by any other
means, obtain payment (voluntary or involuntary) in respect of any Standby Loan
or Loans as a result of which the unpaid principal portion of its Standby Loans
shall be proportionately less than the unpaid principal portion of the Standby
Loans of any other Lender, it shall be deemed simultaneously to have purchased
from such other Lender at face value, and shall promptly pay to such other
Lender the purchase price for, a participation in the Standby Loans of such
other Lender, so that the aggregate unpaid principal amount of the Standby
Loans and participations in the Standby Loans held by each Lender shall be in
the same proportion to the aggregate unpaid principal amount of all Standby
Loans then outstanding as the principal amount of its Standby Loans prior to
such exercise of banker's lien, setoff or counterclaim or other event was to
the principal amount of all Standby Loans outstanding prior to such exercise of
banker's lien, setoff or counterclaim or other event; provided, however, that,
if any such purchase or purchases or adjustments shall be made pursuant to this
Section 2.15 and the payment giving rise thereto shall thereafter be recovered,
such purchase or purchases or adjustments shall be rescinded to the extent of
such recovery and the purchase price or prices or adjustment restored without
interest.  The Borrower expressly consents to the foregoing arrangements and
agrees that any Lender holding a participation in a Standby Loan deemed to have
been so purchased may exercise any and all rights of banker's lien, setoff





                                INTERIM FACILITY
<PAGE>   34
or counterclaim with respect to any and all moneys owing by the Borrower to
such Lender by reason thereof as fully as if such Lender had made a Standby
Loan in the amount of such participation.

         SECTION 2.16.  PAYMENTS.  (a)  The Borrower shall make each payment
(including principal of or interest on any Borrowing or any Fees or other
amounts) hereunder from an account in the United States not later than 10:00
a.m., Houston time, on the date when due in dollars to the Administrative Agent
at its offices at 707 Travis Street, 8-CBBN-N 96, Houston, Texas 77002, in
immediately available funds.

         (b)     Whenever any payment (including principal of or interest on
any Borrowing or any Fees or other amounts) hereunder shall become due, or
otherwise would occur, on a day that is not a Business Day, such payment may be
made on the next succeeding Business Day, and such extension of time shall in
such case be included in the computation of interest or Fees, if applicable.

         SECTION 2.17.  TAXES.  (a)  Any and all payments of principal and
interest on any Borrowings, or of any Fees or indemnity or expense
reimbursements by the Borrower hereunder ("BORROWER PAYMENTS") shall be made,
in accordance with Section 2.16, free and clear of and without deduction for
any and all current or future United States Federal, state and local taxes,
levies, imposts, deductions, charges or withholdings, and all liabilities with
respect to such Borrower Payments, but only to the extent reasonably
attributable to such Borrower Payments, excluding (i) income taxes imposed on
the net income of the Administrative Agent, the CAF Agent or any Lender (or any
transferee or assignee thereof, including a participation holder (any such
entity a "TRANSFEREE")) and (ii) franchise taxes imposed on the net income of
the Administrative Agent, the CAF Agent or any Lender (or Transferee), in each
case by the jurisdiction under the laws of which the Administrative Agent, the
CAF Agent or such Lender (or Transferee) is organized or doing business through
offices or branches located therein, or any political subdivision thereof (all
such nonexcluded taxes, levies, imposts, deductions, charges, withholdings and
liabilities, collectively or individually, "TAXES").  If the Borrower shall be
required to deduct any Taxes from or in respect of any sum payable hereunder to
any Lender (or any Transferee) or the Agents, (i) the sum payable shall be
increased by the amount (an "ADDITIONAL AMOUNT") necessary so that after making
all required deductions (including deductions applicable to additional sums
payable under this Section 2.17) such Lender (or Transferee) or Agent (as the
case may be) shall receive an amount equal to the sum it would have received
had no such deductions been made, (ii) the Borrower shall make such deductions
and (iii) the Borrower shall pay the full amount deducted to the relevant
Governmental Authority in accordance with applicable law.

         (b)     In addition, the Borrower shall pay to the relevant United
States Governmental Authority in accordance with applicable law any current or
future stamp or documentary taxes or any other excise or property taxes,
charges or similar levies that arise from any payment made





                                INTERIM FACILITY
<PAGE>   35
hereunder or from the execution, delivery or registration of, or otherwise with
respect to, this Agreement or the Letter Agreement ("OTHER TAXES").

         (c)     The Borrower shall indemnify each Lender (or Transferee
thereof) and each Agent for the full amount of Taxes and Other Taxes with
respect to Borrower Payments paid by such Lender (or Transferee) or such Agent,
as the case may be, and any liability (including penalties, interest and
expenses (including reasonable attorney's fees and expenses)) arising therefrom
or with respect thereto, whether or not such Taxes or Other Taxes were
correctly or legally asserted by the relevant United States Governmental
Authority.  A certificate setting forth and containing an explanation in
reasonable detail of the manner in which such amount shall have been determined
and the amount of such payment or liability prepared by a Lender, the CAF
Agent, or the Administrative Agent on their behalf, absent manifest error,
shall be final, conclusive and binding for all purposes.  Such indemnification
shall be made within 30 days after the date the Lender (or Transferee) or any
Agent, as the case may be, makes written demand therefor.

         (d)     If a Lender (or Transferee) or any Agent shall become aware
that it is entitled to claim a refund from a United States Governmental
Authority in respect of Taxes or Other Taxes as to which it has been
indemnified by the Borrower, or with respect to which the Borrower has paid
additional amounts, pursuant to this Section 2.17, it shall promptly notify the
Borrower of the availability of such refund claim and shall, within 30 days
after receipt of a request by the Borrower, make a claim to such United States
Governmental Authority for such refund at the Borrower's expense.  If a Lender
(or Transferee) or any Agent receives a refund (including pursuant to a claim
for refund made pursuant to the preceding sentence) in respect of any Taxes or
Other Taxes as to which it has been indemnified by a Borrower or with respect
to which a Borrower had paid additional amounts pursuant to this Section 2.17,
it shall within 30 days from the date of such receipt pay over such refund to
the Borrower (but only to the extent of indemnity payments made, or additional
amounts paid, by the Borrower under this Section 2.17 with respect to the Taxes
or Other Taxes giving rise to such refund), net of all out-of-pocket expenses
of such Lender (or Transferee) or such Agent and without interest (other than
interest paid by the relevant United States Governmental Authority with respect
to such refund); provided, however, that the Borrower, upon the request of such
Lender (or Transferee) or such Agent, agrees to repay the amount paid over to
the Borrower (plus penalties, interest or other charges) to such Lender (or
Transferee) or such Agent in the event such Lender (or Transferee) or such
Agent is required to repay such refund to such United States Governmental
Authority.

         (e)     As soon as practicable, but in any event within 30 days, after
the date of any payment of Taxes or Other Taxes by the Borrower to the relevant
United States Governmental Authority, the Borrower will deliver to the
Administrative Agent, at its address referred to in Section 8.01, the original
or a certified copy of a receipt issued by such United States Governmental
Authority evidencing payment thereof.

<PAGE>   36
         (f)     Without prejudice to the survival of any other agreement
contained herein, the agreements and obligations contained in this Section 2.17
shall survive the payment in full of the principal of and interest on all Loans
made hereunder.

         (g)     Each Lender or Agent (or Transferee) that is organized under
the laws of a jurisdiction other than the United States, any State thereof or
the District of Columbia (a "NON-U.S. LENDER" or "NON U.S. AGENT", as
applicable) shall deliver to the Borrower and the Administrative Agent two
copies of either United States Internal Revenue Service Form 1001 or Form 4224,
properly completed and duly executed by such Non-U.S. Lender claiming complete
exemption from, or reduced rate of, United States Federal withholding tax on
payments by the Borrower under this Agreement.  Such forms shall be delivered
by each Non-U.S. Lender on or before the date it becomes a party to this
Agreement (or, in the case of a Transferee that is a participation holder, on
or before the date such participation holder becomes a Transferee hereunder)
and on or before the date, if any, such Non-U.S. Lender changes its applicable
lending office by designating a different lending office (a "NEW LENDING
OFFICE").  In addition, each Non-U.S. Lender shall deliver such forms promptly
upon the obsolescence or invalidity of any form previously delivered by such
Non-U.S. Lender.  Notwithstanding any other provision of this Section 2.17(g),
a Non-U.S. Lender shall not be required to deliver any form pursuant to this
Section 2.17(g) that such Non-U.S. Lender is not legally able to deliver.

         (h)     The Borrower shall not be required to indemnify any Non-U.S.
Lender or Non-U.S. Agent (including any Transferee), or to pay any additional
amounts to any Non-U.S. Lender or Non-U.S. Agent (including any Transferee), in
respect of United States Federal, state or local withholding tax pursuant to
paragraph (a) or (c) above to the extent that (i) the obligation to withhold
amounts with respect to United States Federal, state or local withholding tax
existed on the date such Non-U.S. Lender became a party to this Agreement (or,
in the case of a Transferee that is a participation holder, on the date such
participation holder became a Transferee hereunder) or, with respect to
payments to a New Lending Office, the date such Non-U.S. Lender designated such
New Lending Office with respect to a Loan; provided, however, that this clause
(i) shall not apply to any Transferee or New Lending Office that becomes a
Transferee or New Lending Office as a result of an assignment, participation,
transfer or designation made at the request of the Borrower; and provided
further, however, that this clause (i) shall not apply to the extent the
indemnity payment or additional amounts any Transferee, or Lender (or
Transferee) through a New Lending Office, would be entitled to receive (without
regard to this clause (i)) do not exceed the indemnity payment or additional
amounts that the person making the assignment, participation or transfer to
such Transferee, or Lender (or Transferee) making the designation of such New
Lending Office, would have been entitled to receive in the absence of such
assignment, participation, transfer or designation or (ii) the obligation to
pay such additional amounts or such indemnity payments would not have arisen
but for a failure by such Non-U.S. Lender (including any Transferee) to comply
with the provisions of paragraph (g) above and (i) below.

<PAGE>   37
         (i)     Any Lender (or Transferee) claiming any indemnity payment or
additional amounts payable pursuant to this Section 2.17 shall use reasonable
efforts (consistent with legal and regulatory restrictions) to file any
certificate or document reasonably requested in writing by the Borrower or to
change the jurisdiction of its applicable lending office if the making of such
a filing or change would avoid the need for or reduce the amount of any such
indemnity payment or additional amounts that may thereafter accrue and would
not, in the good faith determination of such Lender (or Transferee), be
otherwise disadvantageous to such Lender (or Transferee).

         (j)     Nothing contained in this Section 2.17 shall require any
Lender (or Transferee) or any Agent to make available to the Borrower any of
its tax returns (or any other information) that it deems to be confidential or
proprietary.

         SECTION 2.18.  ASSIGNMENT OF COMMITMENTS UNDER CERTAIN CIRCUMSTANCES.
In the event that any Lender shall have delivered a notice or certificate
pursuant to Section 2.12 or 2.13, or the Borrower shall be required to make
additional payments to any Lender under Section 2.17, the Borrower shall have
the right, at its own expense, upon notice to such Lender and the Agents, to
require such Lender to transfer and assign without recourse (in accordance with
and subject to the restrictions contained in Section 8.04) all such Lender's
interests, rights and obligations contained hereunder to another financial
institution approved by the Agents and the Borrower (which approval shall not
be unreasonably withheld) which shall assume such obligations; provided that
(i) no such assignment shall conflict with any law, rule or regulation or order
of any Governmental Authority and (ii) the assignee or the Borrower, as the
case may be, shall pay to the affected Lender in immediately available funds on
the date of such assignment the principal of and interest accrued to the date
of payment on the Loans made by it hereunder and all other amounts accrued for
its account or owed to it hereunder.

Borrower is subject, (B) any order of any Governmental Authority or (C) any

in full force and effect, (ii) sufficient for their purpose and (iii) not

respect to the Pro Forma Financial Statements are set forth therein.

         (d)     Since September 30, 1997, there has been no Material Adverse

governmental body, agency or official in which there is a reasonable
possibility of an adverse decision which could materially adversely affect the
ability of the Borrower to pay its obligations hereunder or which in any manner
draws into question the validity of this Agreement.

         SECTION 3.07.  FEDERAL RESERVE REGULATIONS.         (a)  Neither the

important activities, in the business of extending credit for the purpose of

to refund indebtedness originally incurred for such purpose, or for any other





                                INTERIM FACILITY

purpose which entails a violation of, or which is inconsistent with, the

         SECTION 3.09.  NO MATERIAL MISSTATEMENTS.  No report, financial
statement or other written information furnished by or on behalf of the
Borrower to the Agents or any Lender pursuant to or in connection with this
Agreement contains or will contain any material misstatement of fact or omits
or will omit to state any material fact necessary to make the statements
therein, in the light of the circumstances under which they were or will be
made, not misleading.

         SECTION 3.10.  TAXES.  The Borrower and its Subsidiaries have filed or
caused to be filed within 3 days of the date on which due, all Federal and

received any notification that any Multiemployer Plan is in reorganization or
has been terminated within the meaning of Title IV of ERISA, which such
reorganization or termination could result in a Material Adverse Change, and no
Multiemployer Plan is reasonably expected to be in reorganization or to be
terminated where such reorganization or termination has resulted or can

contemplated by the financial statements or other reports of the type referred
to in Section 5.03 hereof and which have been delivered to the Lenders on or
prior to the date hereof, the Borrower and each of its Subsidiaries has
complied in all material respects with all Federal, state, local and other
statutes, ordinances, orders, judgments, rulings and regulations relating to
environmental pollution or to environmental or nuclear regulation or control,
except to the extent that failure to so comply could not reasonably be expected
to result in a Material Adverse Change.  Except as set forth in or contemplated
by such financial statements or other reports, neither the Borrower nor any of
its Subsidiaries has received notice of any material failure so to comply,
except where such failure could not reasonably be expected to result in a
Material Adverse Change.  Except as set forth in or contemplated by such
financial statements or other reports, the facilities of the Borrower or any of

contemplated by such financial statements or other reports, the Borrower is
aware of no events, conditions or circumstances involving environmental
pollution or contamination that could reasonably be expected to result in a
Material Adverse Change.

neither the Borrower nor any of its Subsidiaries will acquire any Subsidiary or
make any investment in any Subsidiary if, upon giving effect to such
acquisition or investment, as the case may be, the Borrower would not be in
compliance with the covenants set forth in Sections 5.11 and 5.12 and (c)
nothing in this Section shall prohibit any sales of assets permitted by Section
5.10(d).

         SECTION 5.10.  LIMITATIONS ON LIENS.  Neither the Borrower nor any

property or assets subject to an understanding or agreement, contingent or
otherwise, to repurchase such property or assets, or sell, or permit any
Significant Subsidiary to sell, any accounts receivable; provided that the

         days after the acquisition solely for the purpose of financing the
         acquisition of such property), or Liens existing on any such property
         at the time of acquisition of such property by the Borrower or such
         Significant Subsidiary, whether or not assumed, or any Lien in respect
         of property of a corporation existing at the time such corporation
         becomes a Subsidiary of the Borrower; or agreements to acquire any
         property or assets under conditional sale agreements or other title
         retention agreements, or capital leases in respect of any other
         property; provided that

                          (1)     the aggregate principal amount of

                 property shall not exceed the cost (as determined by the board
                 of directors of the Borrower or such Significant Subsidiary,
                 as the case may be) of such property at the time of
                 acquisition thereof (or (x) in the case of property covered by
                 a capital lease, the fair market value, as so determined, of
                 such property at the time of such transaction, or (y) in the

                 to the property originally subject thereto and fixed
                 improvements constructed thereon; or

         foregoing paragraph (b) for amounts not exceeding the principal amount
         of the Indebtedness so refunded or extended or the fair market value
         (as determined by the board of directors of the Borrower or such
         Significant Subsidiary, as the case may be) of the property
         theretofore subject to such Lien, whichever shall be lower, in each
         case at the time of such refunding or extension; provided that such

         mineral to be produced from the property subject thereto and to be
         sold or delivered by the Borrower or any Significant Subsidiary; or

                 (f)      any Lien including in connection with sale-leaseback

         In order to expedite the transactions contemplated by this Agreement,
Chase Bank of Texas, National Association is hereby appointed to act as
Administrative Agent and Chase is hereby appointed to act as CAF Agent, on
behalf of the Lenders.  Each of the Lenders hereby irrevocably authorizes the
Agents to take such actions on behalf of such Lender or holder and to exercise
such powers as are specifically delegated to the Agents by the terms and
provisions hereof, together with such actions and powers as are reasonably
incidental thereto.  The Administrative Agent is hereby expressly authorized by
the Lenders and the CAF Agent, without hereby limiting any implied authority,
(a) to receive on behalf of the Lenders and the CAF Agent all payments of
principal of and interest on the Loans and all other amounts due to the Lenders
and the CAF Agent hereunder, and promptly to distribute to each Lender and the
CAF Agent its proper share of each payment so received; (b) to give notice on
behalf of each of the Lenders to the Borrower of any Event of Default of which
the Administrative Agent has actual knowledge acquired in connection with its
agency hereunder; and (c) to distribute to each Lender copies of all notices,
financial statements and other materials delivered by the Borrower pursuant to
this Agreement as received by the Administrative Agent.

         No Agent or any of its directors, officers, employees or agents shall
be liable as such for any action taken or omitted by any of them except for its
or his or her own gross negligence or willful misconduct, or be responsible for
any statement, warranty or representation herein or the contents of any
document delivered in connection herewith, or be required to ascertain or to
make any inquiry concerning the performance or observance by the Borrower of
any of the terms, conditions, covenants or agreements contained in this
Agreement.  The Agents shall not be responsible to the Lenders for the due
execution, genuineness, validity, enforceability or effectiveness of this
Agreement or other instruments or agreements.  The Agents may deem and treat
the Lender which makes any Loan as the holder of the indebtedness resulting
therefrom for all purposes hereof until it shall have received notice from such
Lender, given as provided herein, of the transfer thereof.  The Agents shall in
all cases be fully protected in acting, or refraining from acting, in
accordance with written instructions signed by the Required Lenders and, except
as otherwise specifically provided herein, such instructions and any action or
inaction pursuant thereto shall be binding on all the Lenders.  Each of the
Agents shall, in the absence of knowledge to the contrary, be entitled to rely
on any instrument or document believed by it in good faith to be genuine and
correct and to have been signed or sent by the proper person or persons.  No
Agent or any of its directors, officers, employees or agents shall have any
responsibility to the Borrower on account of the failure of or delay in
performance or breach by the other Agent or any Lender of any of its
obligations hereunder or to the other Agent or any Lender on account of the
failure of or delay in performance or breach by any other Lender, the other
Agent or the Borrower of any of their respective obligations hereunder or in
connection herewith.  Each of the Agents may execute any and all duties
hereunder by or through agents or employees and shall be entitled to rely upon
the advice of legal counsel selected by it with respect to all matters arising
hereunder





                                INTERIM FACILITY

and shall not be liable for any action taken or suffered in good faith by it in
accordance with the advice of such counsel.

         The Lenders hereby acknowledge that the Agents shall be under no duty
to take any discretionary action permitted to be taken by it pursuant to the
provisions of this Agreement unless it shall be requested in writing to do so
by the Required Lenders.

         Subject to the appointment and acceptance of a successor Agent as
provided below, either Agent may resign at any time by notifying the Lenders
and the Borrower.  Upon any such resignation, the Required Lenders shall have
the right to appoint a successor Agent acceptable to the Borrower.  If no
successor shall have been so appointed by the Required Lenders and shall have
accepted such appointment within 30 days after the retiring Agent gives notice
of its resignation, then the retiring Agent may, on behalf of the Lenders,
appoint a successor Agent, having a combined capital and surplus of at least
$500,000,000 or an Affiliate of any such bank.  Upon the acceptance of any
appointment as Agent hereunder by a successor bank, such successor shall
succeed to and become vested with all the rights, powers, privileges and duties
of the retiring Agent and the retiring Agent shall be discharged from its
duties and obligations hereunder.  After any Agent's resignation hereunder, the
provisions of this Article and Section 8.05 shall continue in effect for its
benefit in respect of any actions taken or omitted to be taken by it while it
was acting as Agent.

         With respect to the Loans made by it hereunder, each of the Agents, in
its individual capacity and not as an Agent shall have the same rights and
powers as any other Lender and may exercise the same as though it were not an
Agent, and each of the Agents and their Affiliates may accept deposits from,
lend money to and generally engage in any kind of business with the Borrower or
any Subsidiary or other Affiliate thereof as if it were not an Agent.

         Each Lender agrees (i) to reimburse the Agents, on demand, in the
amount of its pro rata share (based on its Commitment hereunder or, if the
Commitments shall have been terminated, the amount of its outstanding Loans) of
any expenses incurred for the benefit of the Lenders in its role as Agent,
including counsel fees and compensation of agents and employees paid for
services rendered on behalf of the Lenders, which shall not have been
reimbursed by the Borrower and (ii) to indemnify and hold harmless each of the
Agents and any of its directors, officers, employees or agents, on demand, in
the amount of such pro rata share, from and against any and all liabilities,
taxes, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind or nature whatsoever which may be
imposed on, incurred by or asserted against it in any way relating to or
arising out of this Agreement or any action taken or omitted by it under this
Agreement to the extent the same shall not have been reimbursed by the
Borrower; provided that no Lender shall be liable to any Agent for any portion
of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements resulting from the gross
negligence or willful misconduct of such Agent or any of its directors,
officers, employees or agents.

reliance upon the Agents or any other Lender and based on such documents and
information as it has deemed appropriate, made its own credit analysis and

other entity), except that all claims made pursuant to such Sections shall be
made through such selling Lender, and (iv) the Borrower, the Agents and the
other Lenders shall continue to deal solely and directly with such selling
Lender in connection with such Lender's rights and obligations under this
Agreement, and such Lender shall retain the sole right to enforce the

by or on behalf of the Borrower; provided that, prior to any such disclosure,
each such assignee or participant or proposed assignee or participant shall
execute an agreement whereby such assignee or participant shall agree (subject
to customary exceptions) to preserve the confidentiality of any such
information.

         (h)     The Borrower shall not assign or delegate any rights and
duties hereunder without the prior written consent of all Lenders, and any
attempted assignment or delegation (except as a consequence of a transaction
expressly permitted under Section 5.09) by the Borrower without such consent
shall be void.

         (i)     Any Lender may at any time pledge all or any portion of its
rights under this Agreement to a Federal Reserve Bank; provided that no such
pledge shall release any Lender from its obligations hereunder or substitute
any such Bank for such Lender as a party hereto.  In order to facilitate such
an assignment to a Federal Reserve Bank, the Borrower shall, at the request of
the assigning Lender, duly execute and deliver to the assigning Lender a
promissory note or notes evidencing the Loans made to the Borrower by the
assigning Lender hereunder.

         SECTION 8.05.  EXPENSES; INDEMNITY.  (a)  The Borrower agrees to pay
all reasonable out-of-pocket expenses incurred by the Agents in connection with
entering into this Agreement or in connection with any amendments,
modifications or waivers of the provisions hereof (but only if such amendments,
modifications or waivers are requested by the Borrower) (whether or not the
transactions hereby contemplated are consummated), or incurred by the Agents or
any Lender in connection with the enforcement of their rights in connection
with this Agreement or in connection with the Loans made hereunder, including
the reasonable fees and disbursements of counsel for the Agents or, in the case
of enforcement following an Event of Default, the Lenders.

         (b)     The Borrower agrees to indemnify each Lender against any loss,
calculated in accordance with the next sentence, or reasonable expense which
such Lender may sustain or incur as a consequence of (a) any failure by the
Borrower to borrow or to refinance, convert or continue any Loan hereunder
(including as a result of the Borrower's failure to fulfill any of the
applicable conditions set forth in Article IV) after irrevocable notice of such
borrowing, refinancing, conversion or continuation has been given pursuant to
Section 2.03 or 2.04, (b) any payment, prepayment or conversion, or assignment
of a Eurodollar Loan or Fixed Rate Loan of the Borrower required by any other
provision of this Agreement or otherwise made or deemed made on a date other
than the last day of the Interest Period, if any, applicable thereto, (c) any
default in payment or prepayment of the principal amount of any Loan or any
part thereof or interest accrued thereon, as and when due and payable (at the
due date thereof, whether by scheduled maturity, acceleration, irrevocable
notice of prepayment or otherwise) or (d) the occurrence of any Event of
Default, including, in each such case, any loss or reasonable expense sustained
or incurred or to be sustained or incurred by such Lender in liquidating or
employing deposits from third parties, or with respect to commitments made or
obligations undertaken with third parties, to effect or maintain any Loan
hereunder or any part thereof as a Eurodollar Loan or a Fixed Rate Loan.  Such
loss shall include an amount equal to the excess, if any, as reasonably
determined by such Lender, of (i) its cost of obtaining the funds for the Loan
being paid, prepaid, refinanced, converted or not borrowed (assumed to be the
LIBO Rate or, in the case of a Fixed Rate Loan, the fixed rate of interest
applicable thereto) for the period from the date of such payment, prepayment,
refinancing or failure to borrow or refinance to the last day of the Interest
Period for such Loan (or, in the case of a failure to borrow or refinance the
Interest Period for such Loan which would have commenced on the date of such
failure) over (ii) the amount of interest (as reasonably determined by such
Lender) that would be realized by such Lender in reemploying the funds so paid,
prepaid or not borrowed or refinanced for such period or Interest Period, as
the case may be.

         (c)     THE BORROWER AGREES TO INDEMNIFY THE AGENTS, EACH LENDER, EACH
OF THEIR AFFILIATES AND THE DIRECTORS, OFFICERS, EMPLOYEES AND AGENTS OF THE
FOREGOING (EACH SUCH PERSON BEING CALLED AN "INDEMNITEE") AGAINST, AND TO HOLD
EACH INDEMNITEE HARMLESS FROM, ANY AND ALL LOSSES, CLAIMS, DAMAGES, LIABILITIES
AND RELATED EXPENSES, INCLUDING REASONABLE COUNSEL FEES AND EXPENSES, INCURRED
BY OR ASSERTED AGAINST ANY INDEMNITEE ARISING OUT OF (i)THE CONSUMMATION OF THE
TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT, INCLUDING THE ACQUISITION, (ii)
THE USE OF THE PROCEEDS OF THE LOANS OR (iii) ANY CLAIM, LITIGATION,
INVESTIGATION OR PROCEEDING RELATING TO ANY OF THE FOREGOING, WHETHER OR NOT
ANY INDEMNITEE IS A PARTY THERETO, INCLUDING ANY OF THE FOREGOING ARISING FROM
THE NEGLIGENCE, WHETHER SOLE OR CONCURRENT, ON THE PART OF ANY INDEMNITEE;
PROVIDED THAT SUCH INDEMNITY SHALL NOT, AS TO ANY INDEMNITEE, BE AVAILABLE TO
THE EXTENT THAT SUCH LOSSES, CLAIMS, DAMAGES, LIABILITIES OR RELATED EXPENSES
(i) ARE DETERMINED BY A FINAL JUDGMENT OF A COURT OF COMPETENT JURISDICTION TO
HAVE RESULTED FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF SUCH
INDEMNITEE OR (ii) RESULT FROM ANY LITIGATION BROUGHT BY SUCH INDEMNITEE
AGAINST THE BORROWER OR BY THE BORROWER AGAINST SUCH INDEMNITEE, IN WHICH A
FINAL, NONAPPEALABLE JUDGMENT HAS BEEN RENDERED AGAINST SUCH INDEMNITEE;
PROVIDED, FURTHER, THAT THE BORROWER AGREES THAT IT WILL NOT, NOR WILL IT
PERMIT ANY SUBSIDIARY TO, WITHOUT THE PRIOR WRITTEN CONSENT OF EACH INDEMNITEE,
SETTLE, COMPROMISE OR CONSENT TO THE ENTRY OF ANY JUDGMENT IN ANY PENDING OR
THREATENED CLAIM, ACTION, SUIT OR PROCEEDING IN RESPECT OF WHICH
INDEMNIFICATION COULD BE SOUGHT UNDER THE INDEMNIFICATION PROVISIONS OF THIS
SECTION 8.05(c) (WHETHER OR NOT ANY INDEMNITEE IS AN ACTUAL OR POTENTIAL PARTY
TO SUCH CLAIM, ACTION, SUIT OR PROCEEDING), UNLESS SUCH SETTLEMENT, COMPROMISE
OR CONSENT DOES NOT INCLUDE ANY STATEMENT AS TO AN ADMISSION OF FAULT,
CULPABILITY OR FAILURE TO ACT BY OR ON BEHALF OF ANY INDEMNITEE AND DOES NOT
INVOLVE ANY PAYMENT OF MONEY OR OTHER VALUE BY ANY INDEMNITEE OR ANY INJUNCTIVE
RELIEF OR FACTUAL FINDINGS OR STIPULATIONS BINDING ON ANY INDEMNITEE.

         (d)     The provisions of this Section shall remain operative and in
full force and effect regardless of the expiration of the term of this
Agreement, the consummation of the transactions contemplated hereby, the
repayment of any of the Loans, the invalidity or unenforceability of any term
or provision of this Agreement or any investigation made by or on behalf of any
Agent or any Lender.  All amounts due under this Section shall be payable on
written demand therefor.

         (e)     A certificate of any Lender or Agent setting forth any amount
or amounts which such Lender or Agent is entitled to receive pursuant to
paragraph (b) of this Section and containing an explanation in reasonable
detail of the manner in which such amount or amounts shall have been determined
shall be delivered to the Borrower and shall be conclusive absent manifest
error.

         SECTION 8.06.  RIGHT OF SETOFF.  If an Event of Default shall have
occurred and be continuing, each Lender is hereby authorized at any time and
from time to time, to the fullest extent permitted by law, to set off and apply
any and all deposits (general or special, time or demand, provisional or final)
at any time held and other indebtedness at any time owing by such Lender to or
for the credit or the account of the Borrower against any of and all the
obligations





                                INTERIM FACILITY
<PAGE>   62
of the Borrower now or hereafter existing under this Agreement held by such
Lender, irrespective of whether or not such Lender shall have made any demand
under this Agreement and although such obligations may be unmatured.  The
rights of each Lender under this Section are in addition to other rights and
remedies (including other rights of setoff) which such Lender may have.

         SECTION 8.07.  APPLICABLE LAW.  THIS AGREEMENT SHALL BE CONSTRUED IN
ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK.

         SECTION 8.08.  WAIVERS; AMENDMENT.  (a)  No failure or delay of either
Agent or any Lender in exercising any power or right hereunder shall operate as
a waiver thereof, nor shall any single or partial exercise of any such right or
power, or any abandonment or discontinuance of steps to enforce such a right or
power, preclude any other or further exercise thereof or the exercise of any
other right or power.  The rights and remedies of the Agents and the Lenders
hereunder are cumulative and are not exclusive of any rights or remedies which
they would otherwise have.  No waiver of any provision of this Agreement or
consent to any departure therefrom shall in any event be effective unless the
same shall be permitted by paragraph (b) below, and then such waiver or consent
shall be effective only in the specific instance and for the purpose for which
given.  No notice or demand on the Borrower or any Subsidiary in any case shall
entitle such party to any other or further notice or demand in similar or other
circumstances.

         (b)     Neither this Agreement nor any provision hereof may be waived,
amended or modified except pursuant to an agreement or agreements in writing
entered into by the Borrower and the Required Lenders; provided, however, that
no such agreement shall (i) decrease the principal amount of, or extend the
maturity of or any scheduled principal payment date or date for the payment of
any interest on any Loan, or waive or excuse any such payment or any part
thereof, or decrease the rate of interest on any Loan, without the prior
written consent of each Lender affected thereby, (ii) increase any Commitment
or decrease the Facility Fee of any Lender without the prior written consent of
such Lender, or (iii) amend or modify the provisions of Section 2.14 or Section
8.04(h), the provisions of this Section or the definition of the "Required
Lenders", without the prior written consent of each Lender; provided further,
however, that no such agreement shall amend, modify or otherwise affect the
rights or duties of the Administrative Agent or the CAF Agent hereunder without
the prior written consent of the Administrative Agent or the CAF Agent, as the
case may be.  Each Lender shall be bound by any waiver, amendment or
modification authorized by this Section and any consent by any Lender pursuant
to this Section shall bind any assignee of its rights and interests hereunder.

         SECTION 8.09.  ENTIRE AGREEMENT.  THIS AGREEMENT (INCLUDING THE
SCHEDULES AND EXHIBITS HERETO) AND THE LETTER AGREEMENT CONSTITUTE A "LOAN
AGREEMENT" AS DEFINED IN SECTION 26.02(A) OF THE TEXAS BUSINESS AND COMMERCE
CODE, AND REPRESENT THE ENTIRE CONTRACT AMONG THE PARTIES RELATIVE TO THE
SUBJECT MATTER HEREOF AND THEREOF.  ANY PREVIOUS AGREEMENT, WHETHER WRITTEN OR
ORAL, AMONG THE PARTIES

<PAGE>   63
WITH RESPECT TO THE SUBJECT MATTER HEREOF IS SUPERSEDED BY THIS AGREEMENT AND
THE LETTER AGREEMENT.  THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE
PARTIES.  NOTHING IN THIS AGREEMENT, EXPRESSED OR IMPLIED, IS INTENDED TO
CONFER UPON ANY PARTY OTHER THAN THE PARTIES HERETO ANY RIGHTS, REMEDIES,
OBLIGATIONS OR LIABILITIES UNDER OR BY REASON OF THIS AGREEMENT.

         SECTION 8.10.  SEVERABILITY.  In the event any one or more of the
provisions contained in this Agreement should be held invalid, illegal or
unenforceable in any respect, the validity, legality and enforceability of the
remaining provisions contained herein shall not in any way be affected or
impaired thereby.  The parties shall endeavor in good- faith negotiations to
replace the invalid, illegal or unenforceable provisions with valid provisions
the economic effect of which comes as close as possible to that of the invalid,
illegal or unenforceable provisions.

         SECTION 8.11.  COUNTERPARTS.  This Agreement may be executed in two or
more counterparts, each of which shall constitute an original but all of which
when taken together shall constitute but one contract, and shall become
effective as provided in Section 8.03.

         SECTION 8.12.  HEADINGS.  Article and Section headings and the Table
of Contents used herein are for convenience of reference only, are not part of
this Agreement and are not to affect the construction of, or to be taken into
consideration in interpreting, this Agreement.

         SECTION 8.13.  INTEREST RATE LIMITATION.  (a)  Notwithstanding
anything herein to the contrary, if at any time the applicable interest rate,
together with all fees and charges which are treated as interest under
applicable law (collectively the "CHARGES"), as provided for herein or in any
other document executed in connection herewith, or otherwise contracted for,
charged, received, taken or reserved by any Lender, shall exceed the maximum
lawful rate (the "MAXIMUM RATE") which may be contracted for, charged, taken,
received or reserved by such Lender in accordance with applicable law, the rate
of interest payable on the Loans of such Lender, together with all Charges
payable to such Lender, shall be limited to the Maximum Rate.

         (b)     If the amount of interest, together with all Charges, payable
for the account of any Lender in respect of any interest computation period is
reduced pursuant to paragraph (a) of this Section and the amount of interest,
together with all Charges, payable for such Lender's account in respect of any
subsequent interest computation period, computed pursuant to Section 2.07,
would be less than the Maximum Rate, then the amount of interest, together with
all Charges, payable for such Lender's account in respect of such subsequent
interest computation period shall, to the extent permitted by applicable law,
be automatically increased to such Maximum Rate; provided that at no time shall
the aggregate amount by which interest paid for the account of any Lender has
been increased pursuant to this paragraph (b) exceed the aggregate amount by
which interest, together with all Charges, paid for its account has theretofore
been reduced pursuant to paragraph (a) of this Section.

         SECTION 8.14.  JURISDICTION; VENUE.  (a) The Borrower hereby
irrevocably and unconditionally submits, for itself and its property, to the
nonexclusive jurisdiction of any New York State court or Federal court of the
United States of America sitting in New York City, and any appellate court from
any thereof, in any action or proceeding arising out of or relating to this
Agreement, or for recognition or enforcement of any judgment, and each of the
parties hereto hereby irrevocably and unconditionally agrees that all claims in
respect of any such action or proceeding may be heard and determined in such
New York State or, to the extent permitted by law, in such Federal court.  Each
of the parties hereto agrees that a final judgment in any such action or
proceeding shall be conclusive and may be enforced in other jurisdictions by
suit on the judgment or in any other manner provided by law.  Subject to the
foregoing and to paragraph (b) below, nothing in this Agreement shall affect
any right that any party hereto may otherwise have to bring any action or
proceeding relating to this Agreement against any other party hereto in the
courts of any jurisdiction.

         (b)     The Borrower hereby irrevocably and unconditionally waives, to
the fullest extent it may legally and effectively do so, any objection which it
may now or thereafter have to the laying of venue of any suit, action or
proceeding arising out of or relating to this Agreement in any New York State
or Federal court.  Each of the parties hereto hereby irrevocably waives, to the
fullest extent permitted by law, the defense of an inconvenient forum to the
maintenance of such action or proceeding in any such court.

         SECTION 8.15.  CONFIDENTIALITY.  Each Lender shall use its best
efforts to hold in confidence all information, memoranda, or extracts furnished
to such Lender (directly or through the Agents) by the Borrower hereunder or in
connection with the negotiation hereof; provided that such Lender may disclose
any such information, memoranda or extracts (i) to its accountants or counsel,
(ii) to any regulatory agency having authority to examine such Lender, (iii) as
required by any legal or governmental process or otherwise by law, (iv) except
as provided in the last sentence of Section 5.03, to any person to which such
Lender sells or proposes to sell an assignment or a participation in its Loans
hereunder, if such other person agrees for the benefit of the Borrower to
comply with the provisions of this Section and (v) to the extent that such
information, memoranda or extracts shall be publicly available or shall have
become known to such Lender independently of any disclosure by the Borrower
hereunder or in connection with the negotiation hereof.  Notwithstanding the
foregoing, any Lender may disclose the provisions of this Agreement and the
amounts, maturities and interest rates of its Loans to any purchaser or
potential purchaser of such Lender's interest in any Loan.

To the Lenders listed on
Schedule 2.01 of each
Credit Agreement referred to below
and from time to time party to such Credit Agreement

Ladies and Gentlemen:

    We advise you that we have acted as counsel to Texas Utilities Company, a
Texas Corporation ("TUC"), in connection with the 364-Day Competitive Advance
and Revolving Credit Facility Agreement (the "CREDIT AGREEMENT"), dated as of
March 6, 1998, among TUC, Chase Bank of Texas, National Association, as
Administrative Agent, The Chase Manhattan Bank, as Competitive Advance Facility
Agent, and the banks listed on Schedule 2.01 thereof (the "LENDERS"), and have
participated in the preparation of or have examined and are familiar with (a)
the current financial statements and reports filed by TUC, TU Electric and
Enserch with the Securities and Exchange Commission pursuant to the Securities
Exchange Act of 1934, as amended, (b) the Credit Agreement, (C) the articles of
incorporation and by-laws of TUC and (d) such other records and documents as we
have deemed necessary for the purposes of this opinion.

    As to those matters stated herein to be "to our knowledge" or "known to us"
such examination has been limited to discussions with and certificates from
officers of TUC and we have not conducted any independent investigation or
verification or taken any action beyond such discussions and certificates, nor
made any search of the records of any Governmental Authority with respect to
such matters.

    Capitalized terms used in this opinion and not defined herein shall have
the respective meanings assigned thereto in the Credit Agreement.  This opinion
is delivered to you pursuant to Section 4.01(c) of the Credit Agreement.

    We are members of the New York Bar and do not hold ourselves out as experts
on the laws of the State of Texas. As to all matters of Texas law (including
incorporation of TUC, titles to properties, franchises, licenses and permits)
we have, with your consent, relied upon an opinion of even date herewith
delivered to you by Worsham, Forsythe & Wooldridge, L.L.P., general





<PAGE>   91
counsel for TUC.  While we represent TUC on a regular basis, our engagement has
been limited to specific matters as to which we were consulted.  We have no
direct knowledge of the day-to-day affairs of TUC and have not reviewed
generally their business affairs.  Accordingly, we are relying upon
representations of TUC contained in the Credit Agreement, in certificates
furnished pursuant thereto, and in certificates furnished to us by officers of
TUC.

    For purposes of the opinions expressed below, we have assumed (i) the
authenticity of all documents submitted to us as originals, (ii) the conformity
to the originals of all documents submitted to us as certified or photostatic
copies and the authenticity of the originals of such copies, (iii) the
genuineness of all signatures other than on behalf of TUC, (iv) the legal
capacity of natural persons, (v) the power, corporate or otherwise, of all
parties other than TUC to enter into and to perform all of their obligations
under such documents, and (vi) the due authorization, execution and delivery of
all documents by all parties other than TUC.

    Based on the foregoing, we are of the opinion that:

    1.  TUC (i) is a corporation duly organized, validly existing and in good
standing under the laws of the State of Texas, (ii) has all requisite power and
authority to own its property and assets and to carry on its business as now
conducted, (iii) is qualified to do business in every jurisdiction within the
United States where such qualification is required, except where the failure so
to qualify would not result in a Material Adverse Change, and (iv) has all
requisite corporate power and authority to execute, deliver and perform its
obligations under the Credit Agreement and to borrow funds thereunder.

    2.  The execution, delivery and performance by TUC of the Credit Agreement
and the Borrowings by it thereunder (collectively, the "TRANSACTIONS") and the
consummation of the Acquisition (i) have been duly authorized by all requisite
corporate action and (ii) will not (a) violate (1) any law, statute, rule or
regulation presently binding on or applicable to TUC, or the articles of
incorporation, as amended, or by-laws of TUC, (2) to our knowledge, any order
of any Governmental Authority presently applicable to TUC or (3) any provision
of any indenture, agreement or other instrument known to us to which TUC or its
property is bound, (b) be in conflict with, result in a breach of or constitute
(alone or with notice or lapse of time or both) a default under any such
indenture, agreement or other instrument or (c) except as contemplated by the
UK Facility Agreement (as defined in the Existing Credit Agreements), result in
the creation or imposition of any lien upon or with respect to any property or
assets of TUC.

    3.  The Credit Agreement has been duly executed and delivered by TUC and
constitutes legal, valid and binding obligations of TUC enforceable against TUC
in accordance with its terms except as enforceability may be limited by
bankruptcy, insolvency, reorganization, moratorium or other similar laws
affecting the enforcement of creditors' rights generally and by general
equitable principles (regardless of whether such enforceability is considered
in a proceeding in equity or at law).





                                     D-1-ii
<PAGE>   92
    4.  No action, consent or approval of, registration or filing with, or any
other action by, any Governmental Authority (including pursuant to the Public
Utility Holding Company Act of 1935, as amended) is required on the part of TUC
in connection with the Transactions or the Acquisition, except such as have
been made or obtained and are in full force and effect and, in the case of the
Acquisition, (vi) expiration or termination of the waiting period under the
Hart-Scott-Rodino Antitrust Improvements Act of 1979 and (vii) [the filing by
TUC of a registration statement on Form S-4] under the Securities Act of 1933,
as amended, relating to shares of common stock of TUC to be issued in
connection with the Acquisition, and action by the Securities and Exchange
Commission declaring said registration statement to be effective under such
Act.

    5.  (a) Neither TUC nor any of its respective Subsidiaries is an
"investment company" as defined in, or subject to regulation under, the
Investment Company Act of 1940, as amended, and (b) TUC and each of its
Subsidiaries is exempt from all provisions of the Public Utility Holding
Company Act of 1935, as amended, and the rules and regulations thereunder,
except for Sections 9(a)(2) and 33 of such Act and the rules and regulations
thereunder, and the execution, delivery and performance by TUC of the Credit
Agreement and the consummation of the Acquisition do not violate any provisions
of such Act or any rule or regulation thereunder.

    6.  Except as described in the Annual Reports on Form 10-K for the year
ended December 31, 1996 and the Quarterly Reports on Form 10-Q for the quarters
ended March 31, 1997, June 30, 1997 and September 30, 1997, filed by TUC, TU
Electric and Enserch with the Securities and Exchange Commission and as set
forth in Schedule 3.06 to the Credit Agreement, to our knowledge there is no
action, suit, or proceeding at law or in equity or by or before any
Governmental Authority now pending or threatened against or affecting TUC, TU
Electric or Enserch (i) which involves the Transactions or (ii) as to which
there is a reasonable possibility of an adverse determination and which, if
adversely determined, could, individually or in the aggregate, result in a
Material Adverse Change.

    7.  To our knowledge, after due inquiry, the proposed use of the proceeds
of the Loans is in accordance with the Credit Agreement and, if so used, will
not violate the Margin Regulations.

    8.  We believe that a New York court would give effect to the provisions of
the Credit Agreement that state that they are to be construed in accordance
with New York law.

                     WORSHAM, FORSYTHE & WOOLDRIDGE, L.L.P.

                                                                  ________, 1998


To the Lenders listed on
Schedule 2.01 of each of the
Credit Agreement referred to below

Ladies and Gentlemen:

    We have acted as general counsel for Texas Utilities Company, a Texas
corporation ("TUC"), in connection with the execution and delivery of the
364-Day Competitive Advance and Revolving Credit Facility Agreement (the
"CREDIT AGREEMENT"), dated as of March 6, 1998, among TUC, the banks listed on
Schedule 2.01 thereof (the "LENDERS"), Chase Bank of Texas, National
Association, as Administrative Agent and The Chase Manhattan Bank, as
Competitive Advance Facility Agent.

    Capitalized terms used in this opinion and not defined herein shall have
the respective meanings assigned thereto in the Credit Agreement.  This opinion
is delivered to you pursuant to Section 4.01(c) of the Credit Agreement.

    In connection with this opinion we have examined a counterpart of the
Credit Agreement executed by TUC and have also made such examination of other
documents and of certificates of public officials and corporate officers of
TUC, and have made such other legal and factual examinations and inquiries as
we have deemed necessary or advisable for the purpose of rendering this
opinion; but as to those matters stated herein to be "to our knowledge" or
"known to us" such examination has been limited to discussions with and
certificates from officers of TUC and we have not conducted any independent
investigation or verification or taken any action beyond such discussions and
certificates, nor made any search of the records of any Governmental Authority
with respect to such matters.

    For purposes of the opinions expressed below, we have assumed (i) the
authenticity of all documents submitted to us as originals, (ii) the conformity
to the originals of all documents submitted to us as certified or photostatic
copies and the authenticity of the originals of such copies, (iii) the
genuineness of all signatures other than on behalf of TUC, (iv) the legal
capacity of natural persons, (v) the power, corporate or otherwise, of all
parties other than TUC to enter into and to perform all of their obligations
under such documents, and (vi) the due authorization, execution and delivery of
all documents by all parties other than TUC.





<PAGE>   95
    Based upon, and subject to, the foregoing and to such further limitations
and qualifications stated below, we are of the opinion that:

    1.  TUC (i) is a corporation duly organized, validly existing and in good
standing under the laws of the State of Texas, (ii) has all requisite power and
authority to own its property and assets and to carry on its business as now
conducted, (iii) is qualified to do business in every jurisdiction within the
United States where such qualification is required, except where the failure so
to qualify would not result in a Material Adverse Change, and (iv) has all
requisite corporate power and authority to execute, deliver and perform its
obligations under the Credit Agreement and to borrow funds thereunder.

    2.  The execution, delivery and performance by TUC of the Credit Agreement
and the Borrowings by it (collectively, the "TRANSACTIONS") and the
consummation of the Acquisition (i) have been duly authorized by all requisite
corporate action and (ii) will not (a) violate (1) any law, statute, rule or
regulation presently binding on or applicable to TUC, or the articles of
incorporation, as amended, or by-laws of TUC, (2) to our knowledge, any order
of any Governmental Authority presently applicable to TUC or (3) any provision
of any indenture, agreement or other instrument known to us to which TUC is a
party or by which TUC or its property is bound, (b) be in conflict with, result
in a breach of or constitute (alone or with notice or lapse of time or both) a
default under any such indenture, agreement or other instrument or (c) result
in the creation or imposition of any lien upon or with respect to any property
or assets now owned or hereafter acquired by TUC.

    3.  The Credit Agreement has been duly executed and delivered by TUC and
constitutes legal, valid and binding obligations of TUC enforceable against TUC
in accordance with its terms except as enforceability may be limited by
bankruptcy, insolvency, reorganization, moratorium or other laws affecting the
enforcement of creditors' rights generally and by general equitable principles
(regardless of whether such enforceability is considered in a proceeding in
equity or at law).

    4.  No action, consent or approval of, registration or filing with, or any
other action by, any Government Authority (including pursuant to the Public
Utility Holding Company Act of 1935, as amended) is required on the part of TUC
in connection with the Transactions or the Acquisition, except as such as have
been made or obtained and are in full force and effect and, in the case of the
Acquisition, (i) expiration or termination of the waiting period under the
Hart- Scott-Rodino Antitrust Improvements Act of 1979 and (ii) [the filing by
the Company of a Registration Statement on Form S-4] under the Securities Act
of 1933, as amended, and action by the Securities and Exchange Commission
declaring said Registration Statement effective.

    5.  Neither TUC nor any of its Subsidiaries is an "investment company" as
defined in, or subject to regulation under, the Investment Company Act of 1940,
as amended.  TUC and each of its Subsidiaries is exempt from all provisions of
the Public Utility Holding Company Act of 1935, as amended, and rules and
regulations thereunder, except for Sections 9(a)(2) and 33 of such





                                     D-2-ii
<PAGE>   96
Act and rules and regulations thereunder, and the execution, delivery and
performance by TUC of the Credit Agreement and the consummation of the
Acquisition do not violate any provision of such Act or any rule or regulation
thereunder.

    6.  Except as described in the Annual Reports on Form 10-K for the year
ended December 31, 1996 and the Quarterly Reports on Form 10-Q for the quarters
ended March 31, 1997, June 30, 1997 and September 30, 1997, filed by TUC, TU
Electric and Enserch with the Securities and Exchange Commission and as set
forth in Schedule 3.06 to the Credit Agreement, to our knowledge there is no
action, suit or proceeding at law or in equity or by or before any Governmental
Authority now pending or threatened against or affecting TUC, TU Electric or
Enserch (i) which involves the Transactions or the Acquisition or (ii) as to
which there is a reasonable possibility of an adverse determination and which,
if adversely determined, would, individually or in the aggregate, result in a
Material Adverse change.

    7.  To our knowledge, TUC is not in violation of any law, rule or
regulation, or in default with respect to any judgment, writ, injunction or
decree of any Governmental Authority, where such violation or default would
result in a Material Adverse Change.

    8.  To our knowledge, after due inquiry, the proposed use of the proceeds
of the Loans is in accordance with the Credit Agreement, and, if so used, will
not violate the Margin Regulations.

    9.  We believe that a Texas court would give effect to the provisions of
the Credit Agreement that state that it is to be construed in accordance with
New York law; provided, however, that we render no opinion as to the
application of New York law that is contrary to a fundamental or public policy
of the State of Texas.

    We are members of the State Bar of Texas and do not purport to be experts
on, nor do we opine as to, the laws of any jurisdiction other than the State of
Texas and the federal laws of the United States.  To the extent that the
opinions hereinabove set forth involve the laws of the State of New York, we
have relied upon the opinion of even date herewith delivered by you by Reid &
Priest LLP, special counsel to TUC.

Agreement.

                           FORWARD-LOOKING STATEMENTS
 
This Offer Document does, and the Incorporated Documents may, include
forward-looking statements. Although Texas Utilities believes its expectations
are based on reasonable assumptions, no assurance can be given that actual
results will not differ from those in the forward-looking statements contained
herein and in the Incorporated Documents. The forward-looking statements
contained herein may be affected by, among other things, the competitive
environment; local, state and national regulatory initiatives that increase
competition, threaten cost and investment recovery and impact rate structures;
the economic climate and growth in the service territories of service providers
within the Texas Utilities Group and the TEG Group; the weather and other
natural phenomena; conditions in capital markets; changes in technology used and
services offered by service providers within the Texas Utilities Group and the
TEG Group; and the ability to achieve the goals described in paragraph 2
("Background to and reasons for the Texas Utilities Offer") of the letter

the Incorporated Documents, see Texas Utilities' most recent Annual Report on
Form 10-K or Quarterly Report on Form 10-Q.
 
                     REDUCTION OF THE ACCEPTANCE CONDITION
 
The Texas Utilities Offer is conditional, amongst other things, on valid
acceptances being received (and not, where permitted, withdrawn) by the Initial
Closing Date in respect of not less than 90 per cent. in nominal value of Energy
Group Shares (including Energy Group Shares represented by Energy Group ADSs) to
which the Texas Utilities Offer relates, or such lesser percentage as TU
Acquisitions may decide, provided that such Condition (the "Acceptance
Condition") shall not be satisfied unless TU Acquisitions and its wholly-owned
subsidiaries shall have acquired or agreed to acquire, whether pursuant to the
Texas Utilities Offer or otherwise, Energy Group Shares (including Energy Group
Shares represented by Energy Group ADSs) carrying in aggregate more than 50 per
cent. of the voting rights then exercisable at general meetings of The Energy
Group and provided further that the Acceptance Condition shall be capable of
being satisfied only at a time when all other Conditions have been satisfied,
fulfilled or waived. TU Acquisitions expects that it will reduce the percentage
of Energy Group Shares (including Energy Group Shares represented by Energy
Group ADSs) required to satisfy the Acceptance Condition at some time prior to
all the Conditions being satisfied, fulfilled or, where permitted, waived. At
least five Business Days prior to any such reduction, TU Acquisitions will
announce that it has reserved the right so to reduce the Acceptance Condition.
TU Acquisitions will not make such an announcement unless it believes that there
is a significant possibility that sufficient Energy Group Shares (including
Energy Group Shares represented by Energy Group ADSs) will be tendered to permit
the Acceptance Condition to be satisfied at such reduced level. Holders of
Energy Group Securities who are not willing to accept the Texas Utilities Offer
if the Acceptance Condition is reduced to the minimum permitted level should
either not accept the Texas Utilities Offer until the Subsequent Offer Period or
be prepared to withdraw their acceptances promptly following an announcement by
TU Acquisitions of its reservation of the right to reduce the Acceptance
Condition.
 
                             RULE 10B-13 EXEMPTION
 
In accordance with normal United Kingdom practice, TU Acquisitions or its
nominees or brokers (acting as agents for TU Acquisitions) or another subsidiary
of Texas Utilities may make certain purchases of Energy Group Securities outside
the United States during the period in which the Texas Utilities Offer remains
open for acceptance and affiliates of Merrill Lynch will continue to act as
market makers and principal traders for Energy Group Shares on the London Stock
Exchange pursuant to relief granted by the SEC staff from Rule 10b-13 under the
Exchange Act. For further details on this relief, see paragraph 3 of Appendix
VIII ("Principal purchases") below.
 
                CONVERSION OF CASH CONSIDERATION INTO US DOLLARS
 
Holders of Energy Group Shares may receive US dollars instead of pounds sterling
on the basis described in paragraph 19(f) ("Currency of cash consideration") of
the letter from Lehman Brothers and Merrill Lynch included in this Offer
Document. Holders of Energy Group ADSs evidenced by Energy Group ADRs, unless
they elect to receive pounds sterling, will receive US dollars on the basis
described in that paragraph. The attention of all holders of Energy Group
Securities is drawn to the description in that paragraph of the mechanism for
converting pounds sterling into US dollars and of the exchange rate risks
attached thereto.

          ENERGY PLAZA - 1601 BRYAN STREET - DALLAS, TEXAS 75201-3411
 
                                                                   10 MARCH 1998
 
To holders of Energy Group Securities and, for information only, to participants
in the Energy Group Share Schemes
 
Dear Sir/Madam
 
                        CASH OFFER FOR THE ENERGY GROUP
 
On 2 March 1998, the Boards of Texas Utilities and The Energy Group announced
that they had reached agreement on the terms of a recommended cash offer for The
Energy Group at a price of 810 pence per Energy Group Share, surpassing the
recommended offer of 765 pence per Energy Group Share announced by PacifiCorp on
3 February 1998. Texas Utilities further announced that, subject to the SEC
declaring the relevant documentation effective, it would, in addition to a full
loan note alternative, also make available a limited share alternative.
 
On 3 March 1998, the Board of Texas Utilities announced, in response to the
increase by PacifiCorp of its offer, an increase in Texas Utilities' offer to
840 pence per Energy Group Share and an increase in the value of the limited
share alternative. Texas Utilities has acquired 77,500,000 Energy Group Shares
at a price of 840 pence per share, representing approximately 14.9 per cent of
The Energy Group's issued share capital.
 
Texas Utilities announced today that the SEC declared the relevant documentation
effective on 6 March 1998. Accordingly, Texas Utilities today confirmed that the
limited share alternative is being made available to holders of Energy Group
Securities who validly accept the Texas Utilities Offer.
 
Holders of Energy Group Securities should note that both the Share Alternative
and the Loan Note Alternative are alternatives to Texas Utilities' full cash
offer and are available at the holder's option.
 
1  THE TEXAS UTILITIES OFFER
 
The Texas Utilities Offer is being made on the following basis:
 
<TABLE>
<S>                                     <C>
FOR EACH ENERGY GROUP SHARE             840 PENCE; AND
FOR EACH ENERGY GROUP ADS               L33.60
</TABLE>
 
representing a premium of 20 pence per Energy Group Share to the Increased
PacifiCorp Offer.
 
Under the Share Alternative, holders of Energy Group Securities who validly
accept the Texas Utilities Offer will be entitled to receive New Texas Utilities
Shares with a value equal to:
 
<TABLE>
<S>                                     <C>
FOR EACH ENERGY GROUP SHARE             865 PENCE; AND
FOR EACH ENERGY GROUP ADS               L34.60
</TABLE>
 
determined as, and subject to the limitations, referred to in paragraph 4 of the
letter from Lehman Brothers and Merrill Lynch.
 
As an alternative to some or all of the cash consideration receivable under the
Texas Utilities Offer, holders of Energy Group Shares who validly accept the
Texas Utilities Offer (apart from US citizens or residents and certain other
overseas persons) may elect to receive Loan Notes instead of cash on the
following basis:
 
<TABLE>
<S>                                     <C>
FOR EVERY L1 OF CASH CONSIDERATION      L1 NOMINAL OF LOAN NOTES

A summary of the tax effects for holders of Energy Group Shares resident for tax
purposes in the UK who accept the Texas Utilities Offer is set out in paragraph
12 of Appendix VIII ("United Kingdom taxation") to this Offer Document. A

citizens or

<PAGE>   10
 
residents of the US, US domestic corporations or otherwise taxed as United
States residents is set out in paragraph 13 of Appendix VIII ("United States
federal income taxation") to this Offer Document.
 
2  BACKGROUND TO AND REASONS FOR THE TEXAS UTILITIES OFFER
 
Texas Utilities has formulated a strategy to position itself to thrive in a more
competitive environment and to identify new business investments that both
capitalise on its core competencies and are complementary to its existing
portfolio of businesses in order to grow earnings, broaden its markets beyond
the traditional service areas and expand customer services.
 
The acquisition of The Energy Group would be further confirmation of Texas
Utilities' commitment to this strategy. The Energy Group comprises a unique
blend of electricity generation, supply and distribution assets, combined with
strengths in natural gas and energy trading. Texas Utilities believes that the
highly complementary nature of these activities to those of Texas Utilities,
combined with The Energy Group's experience of operating within a deregulating
market, will enable the enlarged group to capitalise upon the sharing of the
expertise and best practices that reside within the two groups.
 
Texas Utilities expects the transaction to be earnings and cash flow enhancing
in the first complete year following completion of the Acquisition and
thereafter (prior to considering any synergy or other benefits that the
transaction may give rise to). This statement should not be interpreted to mean
that the future earnings per share of Texas Utilities, as enlarged by the
acquisition of The Energy Group, will necessarily be greater than the historical
published earnings per share of Texas Utilities.
 
3  THE PEABODY SALE AND CERTAIN CONSENTS
 
Subject to certain regulatory consents and to the Texas Utilities Offer becoming
or being declared unconditional in all respects, The Energy Group has agreed to
sell the Peabody Coal Business to an affiliated company of Lehman Merchant for a
cash consideration of approximately $2.3 billion plus the assumption of debt.
The Peabody Sale does not require the approval of holders of Energy Group
Securities in general meeting.
 
The Texas Utilities Offer is subject to, inter alia, certain further regulatory
consents and confirmations. Texas Utilities expects that all consents and
confirmations relating to the Texas Utilities Offer and the Peabody Sale will be
obtained within the normal timetable for an offer in the United Kingdom.
 
4  DIRECTORS, MANAGEMENT AND EMPLOYEES
 
TU Acquisitions has given assurances to the Board of The Energy Group that the
existing employment rights, including pension rights, of all TEG Group
management and employees will be fully safeguarded. Texas Utilities looks
forward to welcoming all TEG Group employees to the Texas Utilities Group.
 
5  ACTION TO BE TAKEN TO ACCEPT THE TEXAS UTILITIES OFFER
 
The procedure for acceptance of the Texas Utilities Offer is set out on pages 27
to 29 of this document and in the Acceptance Form. The Initial Closing Date will
be 10.00 pm (London Time), 5.00 pm (New York City time), on 7 April 1998, unless
extended.

To holders of Energy Group Securities and, for information only, to participants

Dear Sir/Madam
 
                        CASH OFFER FOR THE ENERGY GROUP
 
1  INTRODUCTION
 
This letter contains the formal offer on behalf of TU Acquisitions. The Texas
Utilities Offer and this document are subject to the applicable requirements of
both the United Kingdom City Code and US federal securities laws.
 
2  THE TEXAS UTILITIES OFFER
 
On behalf of TU Acquisitions, we hereby offer to purchase, upon the terms and
subject to the Conditions set out in this document and in the relevant
Acceptance Form, all the Energy Group Securities not already held by TU
Acquisitions, for 840 pence in cash per Energy Group Share and L33.60 in cash
per Energy Group ADS, together with the benefits of the Share Alternative and
the Loan Note Alternative referred to in paragraphs 4 and 5 below and the right
to elect to receive the consideration in US dollars set out in paragraph 19
below.
 
The Texas Utilities Offer values the fully diluted share capital of The Energy
Group at approximately L4.45 billion (assuming the exercise in full of all
outstanding options and the vesting of all outstanding awards under the Energy
Group Share Schemes). The Texas Utilities Offer represents a premium of:
 
     - 20 pence to the Increased PacifiCorp Offer of 820 pence per Energy Group
       Share;
 
     - 49.6 per cent. to the Closing Price of 561.5 pence per Energy Group Share
       on 9 June 1997, the last dealing day before the announcement by The
       Energy Group that it was in talks with PacifiCorp in relation to the
       Original PacifiCorp Offer; and
 
     - 22.5 per cent. to the Closing Price of 685.5 pence per Energy Group Share
       on 23 January 1998, the last dealing day prior to the announcement by The
       Energy Group that it was in talks with parties other than PacifiCorp
       which might lead to an offer.
 
Under the Share Alternative, holders of Energy Group Securities would be
entitled to receive New Texas Utilities Shares with a value equal to 865 pence
for each Energy Group Share and L34.60 for each Energy Group ADS, calculated in
accordance with, and subject to the limitations referred to in, paragraph 4
below.

3  TERMS AND CONDITIONS OF THE TEXAS UTILITIES OFFER
 
The Texas Utilities Offer is subject to the Conditions and further terms set out
in Appendix I below. The following summary of certain of the Conditions and
terms of the Texas Utilities Offer is subject to and qualified in its entirety
by reference to Appendix I below.
 
The Texas Utilities Offer is conditional on, amongst other things, valid
acceptances being received (and not, where permitted, withdrawn) by the Initial
Closing Date in respect of not less than 90 per cent. in nominal value of Energy
Group Shares (including Energy Group Shares represented by Energy Group ADSs) to
which the Texas Utilities Offer relates (the "90 per cent. threshold"), or such
lesser percentage as TU Acquisitions may decide, provided that the Acceptance
Condition shall not be satisfied unless TU Acquisitions and its wholly-owned
subsidiaries shall have acquired or agreed to acquire (in accordance with the
requirements of Notes 4 to 6 of Rule 10 of the City Code, to which reference is
made in paragraph 13(b) of Part B of Appendix I below), whether pursuant to the
Texas Utilities Offer or otherwise, Energy Group Shares (including Energy Group
Shares represented by Energy Group ADSs) carrying in aggregate more than 50 per
cent. of the voting rights then exercisable at general meetings of The Energy
Group and provided further that the Acceptance Condition shall be capable of
being satisfied only at a time when all other Conditions have been satisfied,
fulfilled or waived.
 
TU Acquisitions expects that it will reduce the percentage of Energy Group
Shares (including Energy Group Shares represented by Energy Group ADSs) required
to satisfy the Acceptance Condition at some time prior to all the Conditions
being satisfied, fulfilled or, where permitted, waived. At least five Business
Days prior to any reduction in the percentage of Energy Group Shares (including
Energy Group Shares represented by Energy Group ADSs) required to satisfy the
Acceptance Condition, TU Acquisitions will announce that it has reserved the
right to reduce the Acceptance Condition. TU Acquisitions will not make such an
announcement unless it believes there is a significant possibility that
sufficient Energy Group Securities will be tendered to permit the Acceptance
Condition to be satisfied at such reduced level. Holders of Energy Group
Securities who are not willing to accept the Texas Utilities Offer if the
Acceptance Condition is reduced to the minimum permitted level should either not
accept the Texas Utilities Offer until the Subsequent Offer Period or be
prepared to withdraw their acceptances promptly following an announcement by TU
Acquisitions of its reservation of the right to reduce the Acceptance Condition.
 
The Initial Offer Period will expire at 10.00 pm (London time), 5.00 pm (New
York City time), on 7 April 1998, unless extended. At the conclusion of the
Initial Offer Period, including any extension thereof, if all Conditions have
been satisfied, fulfilled or, where permitted, waived, the Texas Utilities Offer
will be extended for a Subsequent Offer Period of at least 14 calendar days.
Holders of Energy Group Securities will have the right to withdraw their
acceptances of the Texas Utilities Offer during the Initial Offer Period, but
not during the Subsequent Offer Period, except in certain limited circumstances.
TU Acquisitions reserves the right (but will not be obliged) at any time to
extend the Initial Offer Period, provided that TU Acquisitions may not extend
the Initial Offer Period beyond 9 May 1998 without the consent of the Panel. TU
Acquisitions may terminate any extension of the Initial Offer Period (other than
an extension required by the City Code or the Exchange Act) prior to its
scheduled expiry if all Conditions have been satisfied, fulfilled or, where
permitted, waived. In that case, the Initial Offer Period and, consequently,
withdrawal rights, except in certain limited circumstances, will terminate
immediately.
 
                                       10
<PAGE>   14
 
If all of the Conditions are satisfied, fulfilled or, where permitted, waived
within the time permitted, payment for tendered Energy Group Securities will be
made as provided in paragraph 19 ("Settlement") below.
 
If all Conditions are satisfied, fulfilled or, where permitted, waived and TU
Acquisitions acquires or contracts to acquire, pursuant to the Texas Utilities
Offer or otherwise, at least 90 per cent. in nominal value of Energy Group
Shares (including Energy Group Shares represented by Energy Group ADSs) to which
the Texas Utilities Offer relates, it will be entitled to, and intends to,
acquire the remaining Energy Group Securities on the same terms as the Texas
Utilities Offer pursuant to and subject to sections 428 to 430 F (inclusive) of
the Companies Act. See paragraph 9 of Appendix VIII ("Compulsory acquisition")
below.
 
Whether or not TU Acquisitions is in a position to effect the compulsory
acquisition of any outstanding Energy Group Shares in accordance with the
Companies Act as referred to above, and irrespective of the size of any
outstanding minority in The Energy Group, TU Acquisitions intends to seek to
procure, after the Texas Utilities Offer becomes or is declared unconditional,
an application by The Energy Group to the London Stock Exchange for Energy Group
Shares to be delisted and an application by The Energy Group to the NYSE for
Energy Group ADSs to be delisted.
 
Shareholders of corporations organised under the laws of certain US states have,
subject to a number of significant exceptions, "appraisal rights" with respect
to their shares in connection with certain transactions (including mergers,
consolidations and acquisitions). These appraisal rights typically confer on
dissenting shareholders the right to have a court determine the fair value of
their shares and require the surviving or resulting corporation to pay such fair
value to such shareholders. As The Energy Group is incorporated under the laws
of England and Wales, holders of Energy Group Securities have no such appraisal
rights in connection with the Texas Utilities Offer. However, in the event that
the compulsory acquisition procedures referred to herein are available to TU
Acquisitions, holders of Energy Group Securities whose Energy Group Securities
have not been purchased pursuant to the Texas Utilities Offer will have certain
rights under section 430C of the Companies Act to object to their acquisition by
TU Acquisitions under the compulsory acquisition procedures. See paragraph 9 of
Appendix VIII ("Compulsory acquisition") below.
 
4  LIMITED SHARE ALTERNATIVE
 
Subject to the limitations set out below, holders of Energy Group Securities who
validly accept the Texas Utilities Offer may elect to receive, instead of cash
consideration for all (but not part) of their Energy Group Shares (including
Energy Group Shares represented by Energy Group ADSs), that number of New Texas
Utilities Shares with a value (the "Share Alternative Value") equal to 865 pence
for each Energy Group Share based on the average of the closing prices of shares
of Texas Utilities Common Stock on the NYSE for the 20 consecutive dealing days
ending on the day (the "Calculation Day") falling three dealing days prior to
the date on which, in the absence of unforeseen circumstances, TU Acquisitions
intends to declare the Texas Utilities Offer unconditional in all respects. As
soon as practicable after the Share Alternative Ratio, as defined below, has
been calculated, and in any event no later than 3.00 pm (London time), 10.00 am
(New York City time) on the dealing day immediately following the Calculation
Day, TU Acquisitions will announce the Share Alternative Ratio, as defined
below, and state that, in the absence of unforeseen circumstances, it intends to
declare the Texas Utilities Offer unconditional in all respects on the date
falling two dealing days following such announcement. During such two dealing
day period, any person who has tendered his Energy Group Securities will
continue to be entitled to withdraw his acceptance and, at any time before the
end of that period or the Subsequent Offer Period, may retender his Energy Group
Securities using a new Acceptance Form (which he may obtain from the United
Kingdom Receiving Agent or the US Depositary whose details are set out at the
end of this document).
 
For the purpose of determining the number of New Texas Utilities Shares
receivable by a holder of Energy Group ADSs, each Energy Group ADS shall be
deemed to represent four Energy Group Shares.
 
CALCULATION OF ENTITLEMENTS UNDER THE SHARE ALTERNATIVE
 
The number of New Texas Utilities Shares receivable by a holder of Energy Group
Securities who validly elects for the Share Alternative will be based on the
number of Energy Group Shares in respect of which the
                                       11
<PAGE>   15
 
relevant holder has or is deemed to have accepted the Texas Utilities Offer,
scaled down as necessary on the pro rata basis referred to below under the
heading "Limited availability of the Share Alternative". Such scaled down number
of Energy Group Shares will be multiplied by the Share Alternative Ratio and the
resultant figure rounded down to the nearest whole number to determine the
number of New Texas Utilities Shares that will be issued to the relevant holder
of Energy Group Securities. The Share Alternative Ratio for determining the
number of New Texas Utilities Shares per Energy Group Share will be 865 pence
(the "Share Alternative Value") divided by the New Texas Utilities Share Price,
rounded down to the nearest three decimal places and subject to a maximum Share
Alternative Ratio of 0.390. The New Texas Utilities Share Price will be
calculated as the average of the closing prices of shares of Texas Utilities
Common Stock on the NYSE Composite Tape on the 20 consecutive dealing days
ending on the Calculation Day, converted into pounds sterling from US dollars at
the Noon Buying Rate on the Calculation Day and expressed as a number of pence
(rounded up or down to the nearest whole number).
 
By the way of illustration, there follows a worked example of the calculation of
an entitlement under the Share Alternative. Assuming the Calculation Day were 5
March 1998 (the latest practicable dealing day prior to the publication of this
document): the New Texas Utilities Share Price would be 2468 pence (based on the
average of the closing prices of shares of Texas Utilities Common Stock on the
NYSE Composite Tape on the 20 consecutive dealing days ending on such
Calculation Day (being $40.60) and a Noon Buying Rate on that day of $1.6450 per
L1) and the Share Alternative Ratio would be 0.350. Accordingly, a holder of 100
Energy Group Shares or 25 Energy Group ADSs who validly elected for the Share
Alternative in respect of his entire holding would, assuming no requirement for
scaling down of his election, be entitled to receive 35 New Texas Utilities
Shares.
 
The following table illustrates the entitlement of such a holder, assuming the
same Noon Buying Rate of $1.6450 per L1, on the basis of the following possible
New Texas Utilities Share Prices:

VALUE OF THE SHARE ALTERNATIVE
 
The average of the closing prices of shares of Texas Utilities Common Stock for
the 20 consecutive dealing days ending on the Calculation Day may vary from the
average closing price of $40.60 used in the worked example above.
 
TU Acquisitions will announce, at or about 12 noon on a daily basis through the
London Stock Exchange, commencing on the day after the posting of this Offer
Document and concluding on the Calculation Day, the rolling average closing
prices of shares of Texas Utilities Common Stock on the NYSE Composite Tape
calculated on the 20 consecutive dealing days ending on the day immediately
preceding the day on which the announcement is made, converted into pounds
sterling from US dollars at the Noon Buying Rate on the Business Day immediately
preceding the date of such announcement. The announcement will also specify the
Share Alternative Ratio that would apply if the day on which such announcement
is made were the Calculation Day and an illustration of the number of New Texas
Utilities Shares to which a holder of Energy Group Securities who validly
elected for the Share Alternative would become entitled assuming no scaling down
of his election.

LIMITED AVAILABILITY OF THE SHARE ALTERNATIVE
 
The aggregate maximum number of Energy Group Shares (including Energy Group
Shares represented by Energy Group ADSs) which can be exchanged for New Texas
Utilities Shares pursuant to the Share Alternative is limited to 20 per cent. of
the fully diluted number of Energy Group Shares (including Energy Group Shares
represented by Energy Group ADSs). As a result, if elections (including
Potential Elections, as defined below) for the Share Alternative exceed this 20
per cent. limit, it will be necessary to scale down these elections as described
below. If it becomes necessary to calculate such a scale down, then, as a result
of the terms of the Texas Utilities Offer and applicable law, there will need to
be taken into account not only those Energy Group Shares (including Energy Group
Shares represented by Energy Group ADSs) in respect of which elections have been
made for the Share Alternative up to and including the tenth day after the Texas
Utilities Offer becomes wholly unconditional, but also those Energy Group Shares
(including Energy Group Shares represented by Energy Group ADSs) which may be
tendered or otherwise acquired by TU Acquisitions after such tenth day. The
scale down ratio will be determined based on the following formula (which is set
out in full in paragraph 4 of Part B of Appendix I):
 
                           scale down ratio =A
 
                                             --
                                             B+C
 
where: A is 20 per cent. of the fully diluted number of Energy Group Shares
       (including Energy Group Shares represented by Energy Group ADSs);
 
       B is the total number of Energy Group Shares (including Energy Group
       Shares represented by Energy Group ADSs) tendered under the Share
       Alternative up to and including the tenth day after the Texas Utilities
       Offer becomes wholly unconditional; and
 
       C is 100 per cent. of the fully diluted number of Energy Group Shares
       (including Energy Group Shares represented by Energy Group ADSs) which
       may be tendered, or otherwise acquired by TU Acquisitions, following the
       tenth day after the Texas Utilities Offer becomes wholly unconditional
       ("Potential Elections").
 
In order for each holder of Energy Group Shares (including Energy Group Shares
represented by Energy Group ADSs) who has elected for the Share Alternative to
determine the actual number of such tendered Energy Group Shares which will be
exchanged for New Texas Utilities Shares, each such holder would multiply those
Energy Group Shares (including Energy Group Shares represented by Energy Group
ADSs) which he/she tendered by the scale down ratio.
 
An example of the calculation of the scale down ratio is set out below, based on
the following assumptions:
 
<TABLE>

If it becomes necessary to scale down elections for the Share Alternative, each
such election, if validly made, will be scaled down by Lehman Brothers and
Merrill Lynch, as nearly as practicable, by the same proportion as such election
bears to all such elections. Further details of this pro rata scaling down are
set out in paragraph 4 of Part B of Appendix I. The summary in this paragraph 4
is qualified in its entirety by the terms set out in paragraph 4 of Part B of
Appendix I.
 
PAYMENT IN THE EVENT OF SCALING DOWN AND/OR IN LIEU OF FRACTIONAL ENTITLEMENTS
 
No fractions of New Texas Utilities Shares will be issued. In lieu of any such
fraction, a holder of Energy Group Securities electing for the Share Alternative
will receive cash consideration equivalent to such fraction multiplied by the
New Texas Utilities Share Price.
 
To the extent that a valid election for the Share Alternative by a holder of
Energy Group Securities is scaled down, such holder will be entitled to receive,
in addition to the New Texas Utilities Shares to which he will be entitled, the
cash consideration in respect of his Energy Group Securities for which he did
not receive New Texas Utilities Shares as a result of the scaling down as if he
had not elected for the Share Alternative in respect of such Energy Group
Securities.
 
Any cash amounts payable to a holder of Energy Group Securities in lieu of
fractional entitlements and pursuant to any scaling down will be aggregated and,
if the aggregate amount is less than L3.00, will not be paid to holders of
Energy Group Securities but will be retained for the benefit of TU Acquisitions.
 
TEXAS UTILITIES COMMON STOCK
 
The New Texas Utilities Shares will, when issued, rank pari passu in all
respects with the existing issued and outstanding shares of Texas Utilities
Common Stock, including the right to receive any future dividends and other
distributions declared with a record date after the date of issuance of such
shares.
 
The Texas Utilities Common Stock is listed on the NYSE, the CSE and the PSE, but
is not listed on the London Stock Exchange. Texas Utilities has not applied for
admission of shares of Texas Utilities Common Stock to the Official List of the
London Stock Exchange but retains its discretion to make such application.
 
A REGISTRATION STATEMENT, AS AMENDED, COVERING THE OFFER AND SALE OF NEW TEXAS
UTILITIES SHARES PURSUANT TO THE SHARE ALTERNATIVE, HAS BEEN DECLARED EFFECTIVE
BY THE SEC ON 6 MARCH 1998 AND TEXAS UTILITIES INTENDS TO APPLY FOR LISTING OF
SUCH SHARES ON THE NYSE, THE CSE AND THE PSE. HOLDERS OF ENERGY GROUP SHARES WHO
HAVE NO EXISTING ARRANGEMENTS TO TRADE SUCH SHARES SHOULD TAKE INTO ACCOUNT THE
DIFFICULTY AND EXPENSES ASSOCIATED WITH TRADING TEXAS UTILITIES COMMON STOCK
WHEN MAKING THEIR INVESTMENT DECISION WITH RESPECT TO THE TEXAS UTILITIES OFFER
AND IN PARTICULAR THE SHARE ALTERNATIVE.
 
YOUR DECISION AS TO WHETHER TO ELECT TO RECEIVE ANY NEW TEXAS UTILITIES SHARES
UNDER THE SHARE ALTERNATIVE WILL DEPEND UPON YOUR INDIVIDUAL CIRCUMSTANCES
INCLUDING YOUR INVESTMENT CRITERIA AND TAX POSITION. YOU SHOULD BEAR IN MIND
THAT THE POUNDS STERLING VALUE OF AN INVESTMENT IN TEXAS UTILITIES AND ANY
DIVIDEND INCOME FROM THAT INVESTMENT (WHICH IS PAYABLE IN US DOLLARS AND SUBJECT
TO US WITHHOLDING TAX) WILL BE AFFECTED BY THE PREVAILING US DOLLAR/POUNDS
STERLING EXCHANGE RATE. A HISTORY OF THE US DOLLAR/POUNDS STERLING EXCHANGE RATE
FOR THE PAST FIVE YEARS IS SET OUT IN APPENDIX VII OF THIS DOCUMENT.
 
IF YOU ARE IN ANY DOUBT AS TO THE COURSE OF ACTION YOU SHOULD FOLLOW, YOU SHOULD
CONSULT YOUR PROFESSIONAL ADVISER.

5  LOAN NOTE ALTERNATIVE
 
A Loan Note Alternative is available to holders of Energy Group Shares (other
than persons who are citizens or residents of the United States and certain
other overseas shareholders) who validly accept the Texas Utilities Offer, on
the basis of L1 nominal of Loan Notes for every L1 of cash that they would
otherwise receive under the Texas Utilities Offer, subject to aggregate valid
elections being received on or before the date on which the Texas Utilities
Offer becomes or is declared unconditional in all respects for in excess of L1
million nominal value of Loan Notes. If insufficient elections are received,
holders of Energy Group Shares who validly accept the Texas Utilities Offer and
elect for the Loan Note Alternative will instead receive cash in accordance with
the terms of the Texas Utilities Offer. Subject as aforesaid, the Loan Note
Alternative will remain open as long as the Texas Utilities Offer is open for
acceptance. Where an Energy Group shareholder elects or is deemed to have
elected for the Loan Note Alternative in respect of all the Energy Group Shares
for which he has accepted the Texas Utilities Offer, fractional entitlements to
Loan Notes will be disregarded and not paid.
 
Merrill Lynch, as broker to the Texas Utilities Offer, has advised that, based
on market conditions on 5 March 1998 (the latest practicable date prior to the
publication of this document), in their opinion, if the Loan Notes had then been
in issue, the value of each L1 nominal of Loan Notes would have been
approximately 98 pence.
 
In considering the Loan Note Alternative, holders of Energy Group Shares should
note that the obligations of TU Acquisitions are not guaranteed or secured.
 
A summary of the terms of the Loan Notes, including provisions relating to the
calculation of the interest rate on the Loan Notes, is set out in Appendix III
below.
 
6  FINANCIAL EFFECTS OF ACCEPTANCE OF THE TEXAS UTILITIES OFFER
 
The following table shows, for illustrative purposes only, and on the bases and
assumptions set out in the notes below, the financial effects of acceptance of
the Texas Utilities Offer (either entirely for cash or on the basis that

     to 31 March 1997 multiplied by 4 and grossed up by a factor of 100/80.
 
(6)  No account has been taken of any liability to taxation nor the treatment of
     fractions in assessing the financial effects of acceptance.
 
7  ACCOUNTING TREATMENT
 
The Acquisition will be accounted for by Texas Utilities as a "purchase" for
financial accounting purposes in accordance with US GAAP. The purchase price
(i.e., the consideration) will be allocated based on the fair value of The
Energy Group's assets acquired and liabilities assumed. Such allocations will be
made based upon valuations and other studies that have not been finalised as of
the date hereof. The excess of the purchase price of the Acquisition over the
amounts so allocated will be allocated to goodwill.
 
8  REGULATION
 
The Texas Utilities Offer is subject to certain regulatory consents and
confirmations being obtained. Amongst other approaches to relevant regulatory
authorities, TU Acquisitions has submitted a Merger Notice to the Director
General of Fair Trading concerning the Texas Utilities Offer and is in
discussions with the DGES. The Peabody Sale is subject to the conditions
described in paragraph 10 below.
 
It is currently anticipated that all consents and confirmations required under
the Texas Utilities Offer and the Peabody Sale will be received within the
normal timetable for an offer in the United Kingdom.
 
TU Acquisitions will not invoke either of Conditions (d) or (e) of the Texas
Utilities Offer in respect of the DGES seeking, or indicating that it is his
intention to seek, modifications to any of the TEG Group's licences under the
Electricity Act 1989 or undertakings or assurances from any member of the Texas
Utilities Group or the TEG Group provided that such modifications, undertakings
or assurances substantially reflect the assurances proposed by the DGES to
PacifiCorp in connection with the referral of the Original PacifiCorp Offer to
the Monopolies and Mergers Commission (as described in the Monopolies and
Mergers Commission Report relating to the Original PacifiCorp Offer published on
19 December 1997) or are substantially in keeping with the proposals outlined by
the DGES in his consultation paper dated 24 February 1998 regarding
modifications to public electricity supply licences following takeovers.
 
The full text of the Conditions to the Texas Utilities Offer is set out in
Appendix I.
 
Further details of regulatory issues applicable to the Texas Utilities Offer are
set out in paragraph 11 of Appendix VIII ("Legal and regulatory matters") below.
 
9  INFORMATION ON THE TEXAS UTILITIES GROUP
 
TEXAS UTILITIES AND ITS SUBSIDIARIES
 
Texas Utilities is a Texas corporation organized in 1996 for the purpose of
becoming the holding company for TEI, formerly Texas Utilities Company, and
ENSERCH upon the mergers of TEI and ENSERCH with
 
                                       16
<PAGE>   20
 
wholly-owned subsidiaries of Texas Utilities ("Mergers"). At the effective time
of the Mergers, (i) Texas Utilities changed its name from TUC Holding Company to
Texas Utilities Company, (ii) TEI changed its name from Texas Utilities Company
to Texas Energy Industries, Inc., (iii) all shares of common stock of TEI were
automatically converted into an equal number of shares of Texas Utilities Common
Stock, (iv) ENSERCH distributed to its shareholders ENSERCH's entire interest in
its former subsidiaries, Lone Star Energy Plant Operations, Inc. and Enserch
Exploration, Inc., and (v) each share of common stock of ENSERCH was
automatically converted into approximately 0.225 of a share of Texas Utilities
Common Stock.
 
TEI, a Texas corporation, is a holding company whose principal subsidiary, TU
Electric, is an operating public utility company engaged in the generation,
purchase, transmission, distribution and sale of electric energy in the north
central, eastern and western portions of Texas, an area with a population
estimated at 5,890,000. Two other subsidiaries of TEI are engaged directly or
indirectly in public utility operations: (i) SESCO, which is engaged in the
purchase, transmission, distribution and sale of electric energy in ten counties
in the eastern and central parts of Texas, with a population estimated at
125,000 and (ii) TU Australia, which in 1995 acquired the common stock of
Eastern Energy, a company engaged in the purchase, distribution, marketing and
sale of electric energy to approximately 481,000 customers in the Melbourne area
of Australia. Eastern Energy is not affiliated with The Energy Group or any of
its subsidiaries. Neither SESCO nor Eastern Energy generates any electricity.
TEI also has other wholly-owned subsidiaries which perform specialized functions
within the Texas Utilities Company system.
 
ENSERCH, a Texas corporation, is an integrated company focused on natural gas.
ENSERCH operate primarily in the north central and eastern parts of Texas. Its
major business operations are natural gas pipelines, processing, marketing and
distribution. Through these business operations, ENSERCH is engaged in owning
and operating interconnected natural gas transmission lines, underground storage
reservoirs, compressor stations and related properties in Texas; gathering and
processing natural gas to remove impurities and extract liquid hydrocarbons for
sale; and the wholesale and retail marketing of natural gas in several areas of
the United States; and owning and operating approximately 550 local gas utility
distribution systems in Texas.
 
In November 1997, Texas Utilities consummated the acquisition of LCC, a
privately held, independent local exchange telephone company, with sixteen
exchanges that serve approximately 100,000 access lines in the Alto, Conroe and
Lufkin areas of southeast Texas. LCC also provides access services to a number
of interexchange carriers who provide long distance services. LCC owns fiber
optic cable systems which it leases to interexchange carriers, leases radio
communications towers, and provides Internet access, cellular mobile telephone,
radio paging and private branch exchange (PBX) services to local customers. LCC
also provides interchange long distance services, with the primary focus being
on business customers. Approximately 8.7 million shares of Texas Utilities
Common Stock were issued to LCC shareholders in a stock for stock exchange.
Approximately $31 million of LCC's long-term debt remains outstanding.
 
The principal executive offices of Texas Utilities are located at 1601 Bryan
Street, Dallas, Texas 75201-3411; the telephone number is (214) 812-4600.
 
TU Acquisitions, a wholly-owned subsidiary of Texas Utilities, is a public
limited company incorporated in England and Wales on 27 October 1997.
 
SELECTED HISTORICAL AND PRO FORMA TEXAS UTILITIES FINANCIAL DATA
 
The Acquisition will be treated as a purchase for accounting purposes. The
Energy Group assets acquired and liabilities assumed will be recorded at their
fair value.
 
The following selected historical financial data of Texas Utilities for each of
the five years in the period ended 31 December 1997 is derived from the
consolidated financial statements included in the Texas Utilities Current Report

(a)  The year ended 31 December 1993 was affected by the recording of regulatory
     disallowances in TU Electric's Docket 11735. The year ended 31 December
     1995 was affected by the impairment of several nonperforming assets,
     including TU Electric's partially completed Twin Oak and Forest Grove
     lignite-fueled facilities and the New Mexico coal reserves of a subsidiary,
     as well as several minor assets. Such impairment, on an after-tax basis,
     amounted to $802 million. (See the TEI 10-K). The year ended 31 December
     1997 includes a one time base revenue refund of $80 million as a result of
     a settlement with the Public Utility Commission of Texas (PUC) and a fuel
     disallowance charge of $80 million as a result of a fuel reconciliation
     proceeding before the PUC. (See the 26 February 1998 Form 8-K.)

10  INFORMATION ON THE ENERGY GROUP
 
The TEG Group is a diversified international energy group which includes
Eastern, one of the leading integrated electricity and gas groups in the United
Kingdom, and Peabody, the world's largest private producer of coal. The Energy
Group has entered into an agreement to sell the Peabody Coal Business to an
affiliated company of Lehman Merchant, subject to the conditions summarised
under the heading "The Peabody Sale" below.
 
Through Eastern, The Energy Group is involved in a wide range of operations:
 
     - Eastern Generation, the fourth largest generator of electricity in Great
       Britain, currently owns, operates or has an interest in eight power
       stations, representing approximately 10 per cent. of the United Kingdom's
       total registered generating capacity as at 31 March 1997;
 
     - Eastern Power & Energy Trading manages for the TEG Group the price and
       volume risks associated with the generation, wholesaling and sale to end
       users of electricity. These exposures are managed by trading its contract
       portfolio and by bidding Eastern's generation output into the Electricity
       Pool (the electricity trading market in England and Wales). It also has
       small equity interests in three natural gas-producing fields in the North
       Sea;
 
     - Eastern Natural Gas is one of the largest suppliers of natural gas in the
       United Kingdom after Centrica plc; and
 
     - Eastern Electricity is the largest supplier and distributor of
       electricity in England and Wales, with over three million customers and
       an authorised area covering approximately 20,300 sq. km. in the east of
       England and parts of North London.
 
Peabody is the largest producer of coal in the United States and operates 25
underground and surface mines in the United States and three surface mines in
Australia:
 
     - as at 31 March 1997, Peabody owned or controlled 9.5 billion tons of
       proven and probable coal reserves;
 
     - in the six months ended 31 March 1997, Peabody sold 81.4 million tons of
       coal worldwide and had an estimated 14.4 per cent. of the US market; and
 
     - Peabody Australia, one of the ten largest coal producers in Australia,
       has interests in four surface mines in New South Wales, three of which
       are currently in operation. Peabody's equity share of the coal sales of
       these mines amounted to 3.5 million tons in the six months ended 31 March
       1997 and its equity share of the proven and probable reserves associated
       with these mines as at 31 March 1997 amounted to 466 million tons.
 
The Peabody Coal Business also includes Citizens Power, one of the leading US
power marketing firms which was acquired by the TEG Group in May 1997. Its
headquarters are in Boston and it has field offices in Milwaukee, Denver and
Toronto.
 
On a pro forma basis for the year ended 31 March 1997, The Energy Group reported
consolidated turnover of L4,460 million and consolidated profit on ordinary
activities after taxation of L286 million. For the nine months ended 31 December
1997, The Energy Group reported unaudited consolidated turnover of L3,390
million and operating profits of L379 million before exceptional costs
associated with the Original PacifiCorp Offer and restructuring charges.

THE PEABODY SALE
 
Subject to the conditions set out below, The Energy Group has agreed to sell the
Peabody Coal Business to an affiliated company of Lehman Merchant for a cash
consideration of approximately $2.3 billion, payable on completion, plus the
assumption of debt.
 
Information on the Peabody Coal Business is set out above. For the nine months
ended 31 December 1997, the Peabody Coal Business contributed L1,014 million and
L112 million to TEG Group turnover and operating profits respectively.
 
The Peabody Sale is conditional on the fulfilment of conditions to the following
effect:
 
     (a)  the Texas Utilities Offer becoming or being declared unconditional in
          all respects (and the Texas Utilities Offer not at that time being
          publicly opposed by the Board of The Energy Group);
 
     (b)  the waiting period applicable to the Peabody Sale under the US HSR Act
          having expired or been terminated;
 
     (c)  the consent of the Treasurer of the Commonwealth of Australia, acting
          in such capacity or through the body known as the Foreign Investment
          Review Board, having been given to the Peabody Sale (or to any aspect
          thereof as is subject to approval pursuant to the Foreign Acquisitions
          and Takeovers Act of Australia) either unconditionally or subject to
          such conditions as do not have and could not reasonably be expected to
          have a material adverse effect on the value of the relevant companies
          and their subsidiaries (taken as a whole);
 
     (d)  FERC having issued an order approving the Peabody Sale or any aspect
          thereof which shall be subject to regulation by FERC on terms that do
          not have and could not reasonably be expected to have a material
          adverse effect on the value of the relevant companies and their
          subsidiaries (taken as a whole); and
 
     (e)  no order having been issued (and remaining in effect) by any court or
          other governmental authority, and no statute, rule, regulation,
          executive order, decree or other order of any kind existing or having
          been enacted, entered or enforced by any governmental authority, which
          (in any such case to an extent which is material in the context of the
          Peabody Sale) prohibits, restrains or restricts completion of the
          Peabody Sale.
 
In the event that (i) the Peabody Sale is not completed because of a breach of
condition (e) above and (ii) the Renewed PacifiCorp Offer (or any revision of
that offer, including the Increased PacifiCorp Offer) lapses, Texas Utilities
will, subject to certain exceptions, pay The Energy Group a break-fee of $50
million on 2 March 1999.
 
Texas Utilities has entered into an agreement with Lehman Merchant relating to
the Peabody Sale which, inter alia, provides for the parties to make certain
payments to each other to reflect changes in the net assets of the Peabody Coal
Business as shown in a post-completion balance sheet and contains other payment
obligations of Texas Utilities in certain circumstances.
 
Further details in relation to the Peabody Sale are set out in paragraph 6 of
Appendix VIII.

1. The results of operations of Eastern, which was acquired by Hanson in
   September 1995, are included above for periods beginning on or after 1
   October 1995. The net assets of Eastern are included above at 30 September
   1995 and each subsequent date.

3. Turnover for the year ended 30 September 1996 is stated net of a special
   discount to electricity customers of L132 million relating to the flotation
   of National Grid Group plc.
 
4. Operating exceptional items in the year ended 30 September 1996 arise from
   the flotation of National Grid Group plc. See Note 7 to the Financial
   Statements.
 
5. Results for the year ended 30 September 1993 reflect a charge for impairment
   of coal assets of L578 million under The Energy Group's accounting policy for
   the impairment of long-lived assets which, under UK GAAP, is reflected in the
   year such impairment is considered to have been incurred.
 
6. The principal differences between UK GAAP and US GAAP which affect The Energy
   Group are described in Note 30 of Notes to the Financial Statements.
 
7. For the purposes of computing the ratio of earnings to fixed charges,
   earnings consist of income before taxes plus fixed charges (excluding
   capitalised interest). Fixed charges consist of interest expense (including
   capitalised interest), together with an amount representative of the interest
   element of operating lease rentals. Under UK GAAP, fixed charges exceeded
   earnings by L566.9 million for the year ended 30 September 1993. Under US
   GAAP, fixed charges exceeded earnings by L200.0 million in the year ended 30
   September 1996.
 
8. The pro forma operating results for the six months ended 31 March 1996 have
   been prepared on the same basis as that used by The Energy Group for prior
   periods adjusted to reflect net interest payable and taxation as if the
   Demerger had occurred at the beginning of the period. The pro forma
   adjustment to net interest payable reflects an additional pro forma interest
   charge calculated at 6.2 per cent. of the L381 million of additional net debt
   which was assumed would be allocated to The Energy Group on the Demerger. The
   L381 million of assumed additional net debt increased The Energy Group's net
   bank and other borrowings on a pro forma basis at 30 September 1996 to L1,440
   million. The effective rate of 6.2 per cent. is based on the three month
   LIBOR at 30 September 1996 together with the margin payable under The Energy
   Group's credit facilities. The pro forma adjustment to taxation has been
   calculated to reflect the impact of the pro forma adjusted interest charge
   resulting from the assumed change in capital structure of The Energy Group
   following the Demerger and after allowing for group relief surrendered (L30
   million) for no consideration by other Hanson Group companies.
 
11  COMPARATIVE PER SHARE DATA AND COMPARISON OF SHAREHOLDER RIGHTS
 
     The following table illustrates certain historical comparative per share
data of Texas Utilities and The Energy Group for the years ended 31 December
1997 and 30 September 1997, respectively, contained in Appendices IV, V and VI.
The table also illustrates, on a pro forma basis, the same data for a holder of
one Energy Group Share validly electing for the Share Alternative, assuming no

COMPARISON OF SHAREHOLDER RIGHTS
 
     There are a number of differences between the rights attaching to shares of
Texas Utilities Common Stock, as detailed above, and those attaching to Energy
Group Shares. Certain rights attaching to Energy
 
                                       22
<PAGE>   26
 
Group Shares, where those differences exist, are identified below. Such
differences may arise from the differences between legislation and regulations
governing The Energy Group and those governing Texas Utilities as well as
between the constitutional documents of the two companies. The following is not
a complete description of the differences between the rights associated with
Energy Group Shares as compared to Texas Utilities Common Stock. Further, it
does not address the differing rights of holders of Texas Utilities preference
stock.
 
     For a complete understanding of such differences, holders of Energy Group
Securities are referred to the laws and applicable regulations of England, the
United States and the State of Texas, the rules of the London Stock Exchange,
the NYSE, the CSE, the PSE and the constitutional documents of both The Energy
Group and Texas Utilities.
 
General
 
     The Energy Group is incorporated in England and operates in accordance with
the Companies Act. Rules and regulations governing trading of Energy Group
Shares differ from those relating to shares of Texas Utilities Common Stock.
 
Dividends
 
     Pursuant to The Energy Group's articles of association, and subject to the
restrictions of English law, dividends may be declared by the Board of The
Energy Group, or by The Energy Group, on the recommendation of the Board, by
ordinary resolution in an amount not to exceed that recommended by the Board.
 
Meetings
 
     The holders of not less than one tenth of the paid up voting capital of The
Energy Group have the right to requisition general meetings of shareholders.
 
Transfers
 
     The Energy Group's articles of association allow The Energy Group Board, in
its absolute discretion, and without giving any reason for so doing, to refuse
to register certain transfers of shares, being shares which are not fully paid
up, or being shares, whether fully paid up or not, which are in favour of more
than four joint transferees.
 
12  FINANCING
 
TU Acquisitions has arranged appropriate financing in connection with the Texas
Utilities Offer. Texas Utilities and other wholly-owned subsidiaries of Texas
Utilities have arranged their own funding to assist in TU Acquisitions'
financing of the Texas Utilities Offer. Details of the financing arrangements
for the Texas Utilities Offer are set out in paragraph 8 of Appendix VIII
("Financing arrangements") below.
 
13  EMPLOYEE MATTERS AND SHARE SCHEMES
 
(a) MANAGEMENT AND EMPLOYEES
 
TU Acquisitions has given assurances to the Board of The Energy Group that the
existing employment rights, including pension rights, of all TEG Group
management and employees will be fully safeguarded. Texas Utilities looks
forward to welcoming all TEG Group employees to the Texas Utilities Group.
 
(b) THE ENERGY GROUP SHARE SCHEMES
 
The Texas Utilities Offer will extend to any fully paid Energy Group Shares
which are unconditionally allotted or issued while the Texas Utilities Offer is
open for acceptance, including those unconditionally allotted or issued pursuant
to the exercise of options or vesting of awards under the Energy Group Share
Schemes.
 
                                       23
<PAGE>   27
 
Appropriate proposals will be made to participants in the Energy Group Share
Schemes in due course. In relation to the Energy Group Sharesave Scheme, it is
anticipated that, as an additional alternative to the rights provided under the
rules of that scheme, participants will be offered an opportunity to surrender
their existing options in consideration for a cash sum, calculated by reference
to the difference between 840 pence and the exercise price of their options
multiplied by the number of Energy Group Shares that they could have acquired
with their total savings contributions (together with any interest payable
thereon) under the Energy Group Sharesave Scheme up to the date the Texas
Utilities Offer becomes or is declared unconditional in all respects, plus a
further six months' savings contributions.
 
14  UNITED KINGDOM TAXATION
 
TU Acquisitions has been advised that, under United Kingdom legislation and
Inland Revenue practice current at the date of this document, the taxation
treatment of acceptance of the Texas Utilities Offer and, where applicable,
election for the Share Alternative and/or the Loan Note Alternative for holders
of Energy Group Shares who are the beneficial owners of their Energy Group
Shares, hold their Energy Group Shares as an investment (otherwise than under a
personal equity plan), and are resident or ordinarily resident in the United
Kingdom for tax purposes will, in summary, be as follows:
 
(a) TAXATION OF CHARGEABLE GAINS
 
Liability to United Kingdom taxation on chargeable gains ("CGT") will depend on
the particular circumstances of holders of Energy Group Shares and on the form
of consideration received.
 
     -- Cash
 
        To the extent that a holder of Energy Group Shares receives cash under
        the Texas Utilities Offer, this will constitute a disposal, or part
        disposal, of his Energy Group Shares for CGT purposes. Such a disposal
        or part disposal may, depending on that shareholder's individual
        circumstances, give rise to a liability to CGT.
 
     -- Loan Notes
 
        A holder of Energy Group Shares who, either alone or together with
        persons connected with him, holds not more than 5 per cent. of shares
        in, or of any class of debentures of, The Energy Group, will not be
        treated as making a disposal of his Energy Group Shares for CGT purposes
        to the extent that he receives Loan Notes by way of consideration.
 
        A holder of Energy Group Shares who, either alone or together with
        persons connected with him, holds more than 5 per cent. of shares in, or
        of any class of debentures of, The Energy Group is advised that an
        application to the Inland Revenue has been made for clearance under
        section 138 of the Taxation of Chargeable Gains Act 1992. The Inland
        Revenue has not yet granted such clearance. Subject to the granting of
        this clearance, such holder of Energy Group Shares will be treated in
        the manner described in the previous paragraph.
 
        A subsequent disposal of Loan Notes (including their redemption or
        repayment) may give rise to a liability to CGT.
 
     -- New Texas Utilities Shares
 
        To the extent a holder of Energy Group Shares receives New Texas
        Utilities Shares under the Texas Utilities Offer, this will constitute a
        disposal, or part disposal, of his Energy Group Shares for CGT purposes
        for a consideration equal to the market value of the New Texas Utilities
        Shares received at the date the Texas Utilities Offer becomes
        unconditional, or, if later, the date on which the relevant shareholder
        accepts the Texas Utilities Offer. Such a disposal or part disposal may,
        depending on that shareholder's individual circumstances, give rise to a
        liability to CGT.
 
                                       24
<PAGE>   28
 
(b) TAXATION OF INTEREST
 
Payment of interest on the Loan Notes will be made subject to the deduction of
United Kingdom income tax at the lower rate (currently, 20 per cent.). An
individual holder of Loan Notes will generally be liable to income tax in the
United Kingdom on the gross amount of interest received, credit being allowed
for the tax deducted. A corporate holder of Loan Notes will generally bring
interest on the Loan Notes into account as income for the purposes of
corporation tax in the United Kingdom, credit being allowed for the tax
deducted.
 
(c) TAXATION OF DIVIDEND INCOME
 
A holder of Texas Utilities Common Stock (including any New Texas Utilities
Shares issued pursuant to the Share Alternative) will generally be liable to
income tax or corporation tax in the United Kingdom on the aggregate of any
dividend received from Texas Utilities and any tax withheld at source in the US
and any tax withheld in the United Kingdom in relation to that dividend. In
computing that liability to taxation, credit will be given for any tax withheld
in the US and any tax withheld in the United Kingdom.
 
FURTHER INFORMATION ON UNITED KINGDOM TAX LAW AND INLAND REVENUE PRACTICE
CURRENT AT THE DATE OF THIS DOCUMENT IS CONTAINED IN PARAGRAPH 12 OF APPENDIX
VIII ("UNITED KINGDOM TAXATION") BELOW. FURTHER INFORMATION ON US FEDERAL INCOME
TAX CURRENT AT THE DATE OF THIS DOCUMENT IS CONTAINED IN PARAGRAPH 15 OF THIS
LETTER ("US TAXATION") AND IN PARAGRAPH 13 OF APPENDIX VIII ("UNITED STATES
FEDERAL INCOME TAXATION") BELOW.
 
ANY HOLDER OF ENERGY GROUP SHARES WHO IS IN ANY DOUBT ABOUT HIS OWN TAX POSITION
OR WHO IS SUBJECT TO TAXATION IN ANY JURISDICTION OTHER THAN THE UNITED KINGDOM
OR THE US (OR IN BOTH THE UNITED KINGDOM AND THE US) IS STRONGLY RECOMMENDED TO
CONSULT HIS INDEPENDENT PROFESSIONAL ADVISER IMMEDIATELY.
 
15  US TAXATION
 
The paragraphs below address certain current US federal income tax consequences
applicable to holders of Energy Group Securities who are citizens or residents
of the US, US domestic corporations or otherwise taxed as United States
residents. It does not apply to tax issues arising from a holder's particular
circumstances, such as participation in the Energy Group Share Schemes, being a
dealer in securities or holders whose functional currency is not the US dollar.
 
The receipt of cash or of cash and New Texas Utilities Shares pursuant to the
Texas Utilities Offer will be a taxable transaction for US income tax purposes
and may also be a taxable transaction under applicable state, local, foreign and
other tax laws.
 
In general, a holder of Energy Group Securities who sells such securities
pursuant to the Texas Utilities Offer will, for US federal income tax purposes,
recognise gain or loss equal to the difference between such holder's adjusted
tax basis in the Energy Group Securities sold and the amount realized as a
result of the disposition. The amount realized will equal the sum of (i) the
dollar value of the pounds sterling received, and (ii) the fair market value of
any New Texas Utilities Shares received. Such gain or loss generally will be
capital gain or loss. An accrual basis holder of Energy Group Securities who
sells such securities pursuant to the Texas Utilities Offer may have a foreign
currency exchange gain or loss for US federal income tax purposes on account of
currency fluctuations between the sale date and the settlement date, in addition
to the gain or loss recognised by the holder on the disposition of Energy Group
Securities pursuant to the Texas Utilities Offer.
 
FURTHER INFORMATION ON THE APPLICATION OF CURRENT US TAX LAWS IS CONTAINED IN
PARAGRAPH 13 OF APPENDIX VIII ("UNITED STATES FEDERAL INCOME TAXATION") BELOW.
 
ANY HOLDER OF ENERGY GROUP SECURITIES WHO IS IN ANY DOUBT ABOUT HIS OWN TAX
POSITION OR WHO IS SUBJECT TO TAXATION IN ANY JURISDICTION OTHER THAN THE UNITED
KINGDOM OR THE US (OR IN BOTH THE UNITED KINGDOM AND THE US) IS STRONGLY
RECOMMENDED TO CONSULT HIS INDEPENDENT PROFESSIONAL ADVISER IMMEDIATELY.

16  OVERSEAS SHAREHOLDERS
 
The attention of holders of Energy Group Securities who are citizens or
residents of jurisdictions outside the United Kingdom or the US is drawn to
paragraph 9 of Part B of Appendix I ("Overseas shareholders") below and to the
relevant provisions of the Acceptance Form.
 
The Texas Utilities Offer is not being made, directly or indirectly, in or into
Canada, Australia or Japan. Persons who are citizens or residents of such
jurisdictions may not accept the Texas Utilities Offer. Any purported acceptance

to this document will be disregarded.
 
The New Texas Utilities Shares have been registered under the Securities Act.
However, such shares will not be the subject of a prospectus under the

New Texas Utilities Shares be registered under any relevant securities laws of
any other country. The New Texas Utilities Shares are not being offered, sold or
delivered, directly or indirectly, in or into Canada, Australia or Japan.

and will not be, registered under the Securities Act or under any relevant
securities laws of any state or district of the United States and will not be
the subject of a prospectus under the securities laws of any province of Canada.
In addition, no steps have been taken, or will be taken, to enable the Loan
Notes to be offered in Japan in compliance with applicable securities laws of
Japan and no prospectus in relation to the Loan Notes has been, or will be,

     the share certificate(s) and/or other document(s) of title for your Energy
     Group Shares, should be returned by post or by hand to The Royal Bank of

     Any Form of Acceptance received in an envelope postmarked in Canada,

     for overseas shareholders, see paragraph 16 ("Overseas shareholders") above
     and paragraph 9 of Part B of Appendix I ("Overseas shareholders") below.
 
     (v) ENERGY GROUP SHARES IN UNCERTIFICATED FORM (THAT IS, IN CREST)
 
     If your Energy Group Shares are in uncertificated form (that is, if you do
     not have a paper share certificate because your shares are held in CREST),
     you should read carefully paragraphs 11(d)-(l) of Part B of Appendix I,
     which set out the acceptance procedures for holders of Energy Group Shares
     in uncertificated form.
 
     If you are a CREST sponsored member, you should refer to your CREST sponsor
     before taking any action.
 
     (vi) SHARE CERTIFICATES NOT READILY AVAILABLE OR LOST
 
     If your Energy Group Shares are in certificated form, but your share
     certificate(s) and/or other document(s) of title is/are not readily
     available or is/are lost, the Form of Acceptance should nevertheless be
     completed, signed and returned as stated in paragraph (iv) above so as to
     arrive no later than 10.00 pm (London time), 5.00 pm (New York City time)
     on 7 April 1998, together with any share certificate(s) and/or other
     document(s) of title that you have available, accompanied by a letter
     stating that the balance will follow. You should then arrange for the
     relevant share certificate(s) and/or other document(s) of title to be
     forwarded as soon as possible thereafter. No acknowledgement of receipt of
     documents will be given. In the case of loss, you should write as soon as
     possible to LLOYDS BANK REGISTRARS, THE CAUSEWAY, GORING-BY-SEA, WORTHING,
     WEST SUSSEX BN99 6 DA for a letter of indemnity for lost share
     certificate(s) and/or other document(s) of title which, when completed in

     Bank of Scotland plc as stated above.

     (vii) DEPOSITS OF ENERGY GROUP SHARES INTO, AND WITHDRAWALS OF ENERGY GROUP
           SHARES FROM, CREST
 
    Normal CREST procedures (including timings) apply in relation to any Energy
    Group Shares that are, or are to be, converted from uncertificated to
    certificated form, or from certificated to uncertificated form, during the
    course of the Texas Utilities Offer (whether any such conversion arises as a
    result of a transfer of Energy Group Shares or otherwise). Holders of Energy
    Group Shares who are proposing so to convert any such shares are recommended
    to ensure that the conversion procedures are implemented in sufficient time
    to enable the person holding or acquiring the shares as a result of the
    conversion to take all necessary steps in connection with an acceptance of
    the Texas Utilities Offer (in particular, as regards delivery of share
    certificate(s) and/or other document(s) of title or transfers to an escrow
    balance as described above) prior to 10.00 pm (London time), 5.00 pm (New
    York City time) on 7 April 1998.
 
(b) HOLDERS OF ENERGY GROUP ADSS
 
The attention of holders of Energy Group ADSs is drawn to paragraph 10 of Part B
of Appendix I ("Procedures for tendering Energy Group ADSs") below and to the
relevant provisions of the Letter of Transmittal.
 
To accept the Texas Utilities Offer, holders of Energy Group ADSs must complete
the Letter of Transmittal in accordance with the instructions printed on it or
comply with the instructions in such Letter of Transmittal applicable to
book-entry transfers. The completed Letter of Transmittal should be sent in the
accompanying reply-paid envelope or delivered by hand together with the required
signature guarantees and any other required documents to the US Depositary at
one of its addresses set forth on the back cover of this document and the Energy
Group ADRs must be either received by the US Depositary at one of such addresses
or delivered in accordance with paragraph 10 of Part B of Appendix I referred to
above.
 
(c) VALIDITY OF ACCEPTANCE
 
Subject to the City Code, TU Acquisitions reserves the right to treat as valid
in whole or in part any acceptance of the Texas Utilities Offer which is not
entirely in order or which is not accompanied (as applicable) by the relevant
transfer to escrow or the relevant share certificate(s) and/or other document(s)
of title or which is received by it in a form or at a place or places other than
set out in this document or the Acceptance Form. In that event, no payment of
cash or issue of Loan Notes or receipts or certificates for New Texas Utilities
Shares under the Texas Utilities Offer will be made until after (as applicable)
the relevant transfer to escrow has settled or the relevant share certificate(s)
and/or other document(s) of title or indemnities satisfactory to TU Acquisitions
have been received.
 
(d) GENERAL
 
No acknowledgement of receipt of Acceptance Forms, share certificates, Energy

18  RIGHTS OF WITHDRAWAL
 
With certain exceptions pursuant to an SEC exemptive order, the Texas Utilities
Offer is subject to the US tender offer rules applicable to securities
registered under the Exchange Act, as well as to the City Code. This has
necessitated a number of changes from the procedures which normally apply to
offers for United Kingdom companies, including those applicable to the rights of
holders of Energy Group Securities to withdraw their acceptance of an offer.
 
                                       28
<PAGE>   32
 
Under the Texas Utilities Offer, holders of Energy Group Securities will be able
to withdraw their acceptances at any time prior to the Initial Closing Date and
in certain other circumstances. The Texas Utilities Offer will not be deemed to
have been validly accepted in respect of any Energy Group Securities which have
been withdrawn.
 
However, the Texas Utilities Offer may be accepted again in respect of the
withdrawn Energy Group Securities by following one of the procedures described
in paragraph 17 ("Procedure for acceptance of the Texas Utilities Offer") above
at any time prior to the expiry or lapse of the Texas Utilities Offer.
 
Further details of these rights of withdrawal and the procedure for effecting
withdrawals are set out in paragraph 3 of Part B of Appendix I ("Rights of
withdrawal") below.
 
19  SETTLEMENT
 
(a) DATE OF PAYMENT
 
The settlement procedure with respect to the Texas Utilities Offer will be
consistent with United Kingdom practice, which differs from the US tender offer
rules in certain material respects, particularly with regard to the date of
payment.
 
Subject to the satisfaction, fulfilment or, where permitted, waiver of all the
Conditions, settlement of acceptances from holders of Energy Group Shares and
accepting holders of Energy Group ADSs or other designated agents will be
effected:
 
     (i)  in the case of acceptances received complete in all respects by the
          Initial Closing Date within 14 calendar days of such date; or
 
     (ii) in the case of acceptances received complete in all respects after 
          such date, but while the Texas Utilities Offer remains open for 
          acceptance, within 14 calendar days of such receipt.
 
(b) ENERGY GROUP SHARES IN UNCERTIFICATED FORM (THAT IS, IN CREST)
 
Where an acceptance relates to Energy Group Shares in uncertificated form, (i)
the cash consideration to which accepting holders of Energy Group Shares are
entitled will be paid by means of CREST by Texas Utilities procuring the
creation of an assured payment obligation in favour of the accepting
shareholders' payment bank in respect of the cash consideration due, in
accordance with the CREST assured payment arrangement; and (ii) definitive
certificates for any New Texas Utilities Shares or Loan Notes or receipts for
New Texas Utilities Shares to which the accepting holder of Energy Group Shares
is entitled will be despatched by post (or by such other method as may be
approved by the Panel).
 
TU Acquisitions reserves the right to settle all or any part of the cash
consideration referred to above, for all or any accepting shareholder(s), in the
manner referred to in paragraph (c) below, if, for any reason, it wishes to do
so.
 
(c) ENERGY GROUP SHARES IN CERTIFICATED FORM AND ENERGY GROUP ADSS
 
Where an acceptance relates to Energy Group Shares in certificated form or
Energy Group ADSs evidenced by Energy Group ADRs, cheques for cash due and,
where applicable, definitive certificates for any New Texas Utilities Shares or
Loan Notes or receipts for New Texas Utilities Shares will be despatched by post
(or by such other method as may be approved by the Panel).
 
(d) LAPSING OF THE TEXAS UTILITIES OFFER
 
If the Conditions are not satisfied, fulfilled or, where permitted, waived, (i)
in respect of Energy Group Shares in certificated form and Energy Group ADRs in
certificated form, the relevant share certificate(s) and/or other documents of
title will be returned by post (or by such other method as may be approved by
the Panel) within 14 days of the Texas Utilities Offer lapsing, (ii) in respect
of Energy Group Shares in uncertificated
 
                                       29
<PAGE>   33
 
form (that is, in CREST) The Royal Bank of Scotland plc will, immediately after
the lapsing of the Texas Utilities Offer (or within such longer period as the
Panel may permit, not exceeding 14 days of the lapsing of the Texas Utilities
Offer), give TFE Instructions to CRESTCo to transfer all relevant Energy Group
Shares held in escrow balances and in relation to which it is the escrow agent
for the purposes of the Texas Utilities Offer to the original available balances
of the holders of Energy Group Shares concerned, and (iii) in respect of Energy
Group ADRs in book-entry form, the US Depository will return such Energy Group
ADRs to the tendering holders unless otherwise instructed by such holder.
 
(e) GENERAL
 
All documents and remittances sent by, to, or from holders of Energy Group
Securities or their appointed agents will be sent at their own risk.
 
All mandates and other instructions in force relating to holdings of Energy
Group Securities will, unless and until revoked, continue in force in relation
to payments of principal and interest under the Loan Notes.
 
(f) CURRENCY OF CASH CONSIDERATION
 
Instead of receiving cash consideration in pounds sterling under the Texas
Utilities Offer, including cash receivable on the scaling down of elections for
the Share Alternative or in lieu of fractional entitlements to New Texas
Utilities Shares, holders of Energy Group Shares who so wish may elect to
receive US dollars on the following basis: the cash amount payable in pounds
sterling to which such holder would otherwise be entitled pursuant to the terms
of the Texas Utilities Offer will be converted, without charge, from pounds
sterling to US dollars at the exchange rate obtainable by the relevant payment
agent (either the United Kingdom Receiving Agent or the US Depositary) on the
spot market in London at approximately noon (London time) on the date the cash
consideration is made available by TU Acquisitions to the relevant payment agent
for delivery in respect of the relevant Energy Group Shares. A holder of Energy
Group Shares may receive such amount on the basis set out above only in respect
of the whole of any cash amounts payable to him under the Texas Utilities Offer.
Holders of Energy Group Securities may not elect to receive both pounds sterling
and US dollars. Unless they elect to receive pounds sterling, holders of Energy
Group ADSs will receive any such cash consideration converted into US dollars as
described above, as if such holders of Energy Group ADSs had elected to receive
US dollars. Consideration in US dollars may be inappropriate for holders of
Energy Group Securities other than persons in the US and holders of Energy Group
ADSs.
 
THE ACTUAL AMOUNT OF US DOLLARS RECEIVED WILL DEPEND UPON THE EXCHANGE RATE
PREVAILING ON THE BUSINESS DAY ON WHICH FUNDS ARE MADE AVAILABLE TO THE RELEVANT
PAYMENT AGENT BY TU ACQUISITIONS. HOLDERS OF ENERGY GROUP SECURITIES SHOULD BE
AWARE THAT THE US DOLLAR/POUNDS STERLING EXCHANGE RATE WHICH IS PREVAILING AT
THE DATE ON WHICH AN ELECTION IS MADE OR DEEMED TO BE MADE TO RECEIVE DOLLARS
AND ON THE DATES OF DESPATCH AND RECEIPT OF PAYMENT MAY BE DIFFERENT FROM THAT
PREVAILING ON THE BUSINESS DAY ON WHICH FUNDS ARE MADE AVAILABLE TO THE RELEVANT
PAYMENT AGENT BY TU ACQUISITIONS. IN ALL CASES, FLUCTUATIONS IN THE US DOLLAR/
POUNDS STERLING EXCHANGE RATE ARE AT THE RISK OF ACCEPTING HOLDERS OF ENERGY
GROUP SECURITIES WHO ELECT OR ARE TREATED AS HAVING ELECTED TO RECEIVE THEIR
CONSIDERATION IN US DOLLARS. NEITHER TU ACQUISITIONS NOR ANY OF ITS ADVISERS OR
AGENTS SHALL HAVE RESPONSIBILITY WITH RESPECT TO THE ACTUAL AMOUNT OF CASH
CONSIDERATION PAYABLE OTHER THAN IN POUNDS STERLING.

     (iii) a contingent or other liability of any member of the wider TEG Group
           having arisen which would be likely adversely to affect any member of
           the wider TEG Group;
 
(l)  TU Acquisitions not having discovered:
 
     (i)   that any financial, business or other information which has been
           publicly disclosed at any time by or on behalf of any member of the
           wider TEG Group is materially misleading, contains a material
           misrepresentation of fact or omits to state a fact necessary to make
           the information contained therein not misleading and which in any
           such case is material in the context of the wider TEG Group taken as
           a whole or of the financing of the Texas Utilities Offer; or

           or emission of any waste or hazardous substance or any substance
           likely to impair the environment or harm human health, which
           non-compliance or any other disposal, discharge, spillage, leak or
           emission which has occurred would be likely to give rise to any
           liability (whether actual or contingent) on the part of any member of
           the wider TEG Group and which is material in the context of the wider
           TEG Group taken as a whole or of the financing of the Texas Utilities
           Offer; or
 
     (ii)  that there is, or is likely to be, any liability (whether actual or

           legislation, regulation, notice, circular or order of any relevant
           authority relating to the protection of or enhancement of the
           environment and which is material in the context of the wider TEG
           Group taken as a whole or of the financing of the Texas Utilities
           Offer.

satisfied, fulfilled or waived. TU Acquisitions shall be under no obligation to

Texas Utilities Offer will also lapse if the Acquisition is referred to the

                                     PART B
 
FURTHER TERMS OF THE TEXAS UTILITIES OFFER
 
The following further terms apply, where the context permits, to the Texas
Utilities Offer.
 
1  ACCEPTANCE PERIOD
 
(a) The Texas Utilities Offer will initially be open until 10.00 pm (London
    time), 5.00 pm (New York City time) on 7 April 1998. TU Acquisitions
    expressly reserves the right (but will not be obliged, other than as may be
    required by the City Code or US federal securities laws and the rules and
    regulations thereunder) at any time or from time to time to extend the Texas
    Utilities Offer after the Initial Closing Date and, in such event, will make
    a public announcement of such extension in the manner described in paragraph
    2 below and give oral or written notice of such extension to the United
    Kingdom Receiving Agent and the US Depositary. TU Acquisitions may terminate
    any such extension (other than an extension required by the City Code or US
    federal securities laws and the rules and regulations thereunder) prior to
    its scheduled expiry if all Conditions have been satisfied or, where
    permitted, waived. If all Conditions have not been satisfied, fulfilled or,
    where permitted, waived by TU Acquisitions by 10.00 pm (London time), 5.00
    pm (New York City time) on the Initial Closing Date, TU Acquisitions
    currently intends, subject to the rules of the City Code, to extend the
    Texas Utilities Offer until such time as all Conditions have been satisfied,
    fulfilled or, where permitted, waived. There can be no assurance, however,
    that TU Acquisitions will, in such circumstances, extend the Texas Utilities
    Offer and, if no such extension is made, the Texas Utilities Offer will
    lapse on the Initial Closing Date and no Energy Group Securities will be
    purchased pursuant to the Texas Utilities Offer.
 
(b) Although no revision is envisaged, if the Texas Utilities Offer is revised,
    the Initial Offer Period will be extended, if necessary, for a period of at
    least 14 calendar days from the date of posting of the revised Texas
    Utilities Offer to holders of Energy Group Securities. Except with the
    consent of the Panel, no revision of the Texas Utilities Offer may be made
    after 25 April 1998.
 
(c) The Initial Offer Period cannot (except with the consent of the Panel) be
    extended beyond midnight (London time), 7.00 pm (New York City time) on 9
    May 1998 (or any earlier time and/or date beyond which TU Acquisitions has
    stated that the Texas Utilities Offer will not be extended and in respect of
    which it has not withdrawn that statement). If all Conditions are not
    satisfied, fulfilled or, where permitted, waived at such time (taking
    account of any prescribed extension of the Initial Offer Period), the Texas
    Utilities Offer will lapse in the absence of a competing bid and/or unless
    the Panel agrees otherwise. If the Texas Utilities Offer lapses for any
    reason, the Texas Utilities Offer shall cease to be capable of further
    acceptance and TU Acquisitions and holders of Energy Group Securities shall
    cease to be bound by prior acceptances. TU Acquisitions reserves the right,
    if appropriate, to seek the Panel's approval to extend the final date for
    expiry of the Initial Offer Period to 30 May 1998, or such later date as the
    Panel may agree. Except with the consent of the Panel, TU Acquisitions may
    not, for the purposes of determining whether the Acceptance Condition has
    been satisfied, take into account acceptances or purchases of Energy Group
    Securities made after 1.00 pm (London time), 8.00 am (New York City time) on
    9 May 1998 (or any other time or date beyond which TU Acquisitions has
    stated that the Texas Utilities Offer will not be extended and in respect of
    which it has not withdrawn that statement) or such later time and/or date as
    TU Acquisitions, with the permission of the Panel, may determine.
 
(d) If all Conditions are satisfied, fulfilled or, where applicable, waived and
    the Initial Offer Period expires, the Texas Utilities Offer will remain open
    for acceptance for the Subsequent Offer Period of not less than 14 calendar
    days from the expiry of the Initial Offer Period. If it is stated that the
    Texas Utilities Offer will remain open until further notice, then not less
    than 14 calendar days' notice will be given prior to the closing of the
    Subsequent Offer Period.
 
(e) If a competitive situation arises after a no extension and/or a no increase
    statement has been made by or on behalf of TU Acquisitions in relation to
    the Texas Utilities Offer, TU Acquisitions may, if it has specifically
    reserved the right to do so at the same time as such statement is made (or
    otherwise with the
                                       I-7
<PAGE>   42
     consent of the Panel), withdraw such statement and be free to extend the
     Texas Utilities Offer if it announces such withdrawal within four Business
     Days after the announcement of the competing offer and gives notice to the
     holders of Energy Group Securities to that effect in writing or (in the
     case of holders of Energy Group Securities with registered addresses
     outside the United Kingdom or the United States or whom TU Acquisitions
     knows to be nominees, trustees or custodians holding Energy Group
     Securities for such persons) by announcement in the United Kingdom and in
     the United States at the earliest opportunity. TU Acquisitions may choose
     not to be bound by the terms of a no extension and/or a no increase
     statement if it would otherwise prevent the posting of an increased or
     improved Texas Utilities Offer, (i) if it has reserved the right to do so,
     and the increased or improved Texas Utilities Offer is recommended for
     acceptance by the Board of Directors of The Energy Group or (ii) with the
     consent of the Panel.
 
(f)  For the purposes of determining whether the Acceptance Condition has been
     satisfied, TU Acquisitions will not be bound (unless otherwise required by
     the Panel) to take into account any Energy Group Securities which have been
     issued or unconditionally allotted, or which arise as the result of the
     exercise of conversion rights, before that determination takes place,
     unless written notice containing relevant details of the allotment, issue
     or conversion has been received from The Energy Group or its agents before
     that time by TU Acquisitions or The Royal Bank of Scotland plc or The Bank
     of New York on behalf of TU Acquisitions at one of the addresses specified
     at the end of this document. Notification by telex or facsimile or other
     electronic transmission will not be sufficient.
 
(g)  In accordance with an SEC exemptive order received by TU Acquisitions, at
     least five Business Days prior to any reduction in the percentage of Energy
     Group Securities required to satisfy the Acceptance Condition, TU
     Acquisitions will announce that it has reserved the right so to reduce the
     Acceptance Condition. TU Acquisitions will not make such an announcement
     unless TU Acquisitions believes there is a significant possibility that
     sufficient Energy Group Securities will be tendered to permit the
     Acceptance Condition to be satisfied at such reduced level. Holders of
     Energy Group Securities who are not willing to accept the Texas Utilities
     Offer if the Acceptance Condition is reduced to the minimum permitted level
     should either not accept the Texas Utilities Offer until the Subsequent
     Offer Period or be prepared to withdraw their acceptance promptly following
     an announcement by TU Acquisitions of its reservation of the right to
     reduce the Acceptance Condition.
 
2  ANNOUNCEMENTS
 
(a)  Without prejudice to paragraph 3 ("Rights of withdrawal") below, by 8.30 am
     (London time) in the United Kingdom and 8.30 am (New York City time) in the
     United States on the Business Day (the "relevant day") next following the
     day on which the Texas Utilities Offer is due to expire or on which all
     Conditions become or are declared to have been satisfied, fulfilled or,
     where applicable, waived or on which the Texas Utilities Offer is revised
     or extended (or such later time and/or date as the Panel may agree), TU
     Acquisitions will make an appropriate announcement and inform the London
     Stock Exchange and the Dow Jones News Service, respectively, of the
     position regarding the Texas Utilities Offer. Such announcements will
     (unless otherwise permitted by the Panel) also state the total number of
     Energy Group Securities and rights over Energy Group Securities (as nearly
     as practicable):
 
     (i)   for which acceptances of the Texas Utilities Offer have been received
           (showing the extent, if any, to which such acceptances have been
           received from persons acting or deemed to be in concert with TU
           Acquisitions);
 
     (ii)  acquired or agreed to be acquired by or on behalf of TU Acquisitions
           and any person acting or deemed to be in concert with TU 
           Acquisitions; and
 
     (iii) held prior to the Initial Offer Period by or on behalf of TU
           Acquisitions and any persons acting or deemed to be in concert with 
           it;
 
     and will specify the percentages of Energy Group Securities represented by
     each of these figures.
 
                                       I-8
<PAGE>   43
 
     In computing the numbers of Energy Group Securities represented by
     acceptances and/or purchases for the above purposes, only those acceptances
     and/or purchases permitted to be counted towards fulfilling the Acceptance
     Condition in accordance with paragraph 13 ("Certain provisions concerning
     acceptances") below shall be included in the totals.
 
(b)  Any decision to extend the Initial Offer Period may be made at any time up
     to, and will be announced not later than, 8.30 am (London time) in the
     United Kingdom and 8.30 am (New York City time) in the United States on the
     relevant day (or such later time and/or date as the Panel may agree) and
     the announcement will state the next expiry date of the Initial Offer
     Period.
 
(c)  References to the making of an announcement by or on behalf of TU
     Acquisitions include the release of an announcement by TU Acquisitions, by
     public relations consultants retained by TU Acquisitions, or by Lehman
     Brothers or Merrill Lynch, to the press and the delivery by hand or
     telephone, facsimile or telex transmission or other electronic transmission
     of an announcement to the London Stock Exchange and the Dow Jones News
     Service, as the case may be. An announcement made otherwise than to the
     London Stock Exchange will be notified simultaneously to the London Stock
     Exchange.
 
(d)  Without limiting the manner in which TU Acquisitions may choose to make any
     public announcement and, subject to TU Acquisitions' obligations under
     applicable law (including Rules 14d-4(c) and 14d-6(d) under the Exchange
     Act relating to TU Acquisitions' obligation to disseminate promptly public
     announcements concerning material changes to the Texas Utilities Offer), TU
     Acquisitions will have no obligation to publish, advertise or otherwise
     communicate any such public announcement other than by making a release to
     the London Stock Exchange and the Dow Jones News Service.
 
3  RIGHTS OF WITHDRAWAL
 
(a)  Except as otherwise provided in this paragraph, tenders of Energy Group
     Securities and elections are irrevocable. Energy Group Securities tendered
     pursuant to the Texas Utilities Offer may be withdrawn pursuant to the
     procedures set out below at any time during the Initial Offer Period and in
     certain other circumstances described below. Energy Group Securities
     tendered during the Initial Offer Period and not validly withdrawn prior to
     the Initial Closing Date, and Energy Group Securities tendered during the
     Subsequent Offer Period, may not be withdrawn. Holders of Energy Group
     Securities will not have withdrawal rights during the Subsequent Offer
     Period, except in certain limited circumstances described below.
 
(b)  If TU Acquisitions, having announced that the Acceptance Condition has been
     satisfied, fails by 3.30 pm (London time), 10.30 am (New York City time) on
     the relevant day (or such later time or date as the Panel may agree) to
     comply with any of the relevant requirements relating to the Texas
     Utilities Offer specified in paragraph 2(a) of this Part B of Appendix I
     above, an accepting holder of Energy Group Securities may immediately after
     that time withdraw his acceptance of the Texas Utilities Offer by written
     notice given by post or by hand to The Royal Bank of Scotland plc or The
     Bank of New York, at any of the relevant addresses specified at the end of
     this document, in each case receiving such notice on behalf of TU
     Acquisitions. This right of withdrawal may be terminated not less than
     eight days after the relevant day by TU Acquisitions confirming, if that be
     the case, that the Texas Utilities Offer is still unconditional and
     complying with the other relevant requirements relating to the Texas
     Utilities Offer specified in paragraph 2(a) of this Part B of Appendix I
     above. If any such confirmation is given, the first period of 14 days
     referred to in paragraph 1 (b) of this Part B of Appendix I above will run
     from the date of that confirmation and compliance.
 
(c)  If a no extension and/or a no increase statement is withdrawn in accordance
     with paragraph 1(e) of this Part B of Appendix I above, any acceptance of
     the Texas Utilities Offer made after the date of that statement may be
     withdrawn thereafter in the manner referred to in paragraph 3(b) of this
     Part B of Appendix I above, for a period of eight days following the date
     on which the notice of the withdrawal of such statement is posted to
     holders of Energy Group Securities.

     be received before the end of the Initial Offer Period by the party (either
     the United Kingdom Receiving Agent or the US Depositary) to whom the
     Acceptance Form was originally sent and must specify the name of the person
     who has tendered the Energy Group Securities, the number of Energy Group
     Securities to be withdrawn and (if certificates have been tendered) the
     name of the registered holder of the relevant Energy Group Securities, if
     different from the name of the person who tendered such Energy Group
     Securities.
 
(e)  In respect of Energy Group ADSs, if Energy Group ADRs have been delivered
     or otherwise identified to the US Depositary, then, prior to the physical
     release of such Energy Group ADRs, the serial numbers shown on such Energy
     Group ADRs must be submitted and, unless the Energy Group ADSs evidenced by
     such Energy Group ADRs have been tendered by an Eligible Institution or by
     means of a Letter of Transmittal, the signatures on the notice of
     withdrawal must be guaranteed by an Eligible Institution. If interests in
     Energy Group ADSs evidenced by Energy Group ADRs have been delivered
     pursuant to the procedures for book-entry transfer set out in paragraph 10
     of this Part B of Appendix I below, any notice of withdrawal must also
     specify the name and number of the account at the appropriate Book-Entry
     Transfer Facility to be credited with the withdrawn Energy Group ADSs and
     must otherwise comply with such Book-Entry Transfer Facility's procedures.
 
(f)  Withdrawals of tendered Energy Group Securities may not be rescinded
     (without TU Acquisitions' consent) and any Energy Group Securities properly
     withdrawn and not properly re-tendered will thereafter be deemed not
     validly tendered for the purposes of the Texas Utilities Offer. Withdrawn
     Energy Group Securities may be subsequently re-tendered, however, by
     following one of the procedures described in either paragraph 10 or
     paragraph 11 of this Part B of Appendix I below, as the case may be, at any
     time whilst the Texas Utilities Offer remains open.
 
(g)  All questions as to the validity (including time of receipt) of any notice
     of withdrawal will be determined by TU Acquisitions, whose determination
     (except as required by the Panel) will be final and binding. None of TU
     Acquisitions, The Energy Group, Lehman Brothers, Merrill Lynch, the US
     Depositary, the United Kingdom Receiving Agent or any other person will be
     under any duty to give notification of any defects or irregularities in any
     notice of withdrawal or incur any liability for failure to give such
     notification.
 
4  LIMITED SHARE ALTERNATIVE
 
(a)  The Share Alternative is conditional upon:
 
     (i)    the Texas Utilities Offer becoming or being declared unconditional
            in all respects;
 
     (ii)   New Texas Utilities Shares having been approved for listing, subject
            to notice of issuance, on the NYSE, the CSE and the PSE; and
 
     (iii)  the Registration Statement remaining effective under the Securities
            Act.
 
(b)  If the conditions referred to in paragraphs 4(a)(ii) and (iii) above are
     not satisfied at the time the Texas Utilities Offer becomes or is declared
     unconditional in all respects, the Share Alternative will lapse and any
     holder of Energy Group Securities who has elected for the Share Alternative
     will be entitled to receive only the cash consideration payable under the
     Texas Utilities Offer (and will be deemed not to have elected for the Share
     Alternative).
 
(c)  (i)  The maximum aggregate number of Energy Group Securities in respect of
          which valid elections for the Share Alternative shall be deemed to
          have been made shall be limited, in such manner as TU Acquisitions may
          decide, so that the total number of Energy Group Shares (including
          Energy Group Shares represented by Energy Group ADSs) acquired by TU
          Acquisitions other than for cash or for Loan Notes, whether pursuant
          to the Texas Utilities Offer or otherwise (and having regard to the
          maximum number of shares which may be issued as a result of the
          exercise of options or subscription rights under the Energy Group
          Share Schemes or otherwise and the maximum level of elections for New
          Texas Utilities Shares which may be made by holders of Energy Group
          Shares whose shares are acquired compulsorily under sections 428 to
          430F
 
                                      I-10
<PAGE>   45
 
          (inclusive) of the Companies Act), shall represent a maximum of 20 per
          cent. of the total number of Energy Group Shares (including Energy
          Group Shares represented by Energy Group ADSs) acquired by TU
          Acquisitions pursuant to the Texas Utilities Offer or otherwise. To
          the extent that total elections for the Share Alternative exceed or
          may exceed this limit, elections will be scaled down on a pro rata
          basis. For the purposes of applying the limit on the maximum aggregate
          number of Energy Group Shares in respect of which valid elections for
          the Share Alternative shall be deemed to have been made and scaling
          down elections for the Share Alternative on a pro rata basis, each
          election for the Share Alternative with respect to an Energy Group ADS
          shall be deemed to be an election for the Share Alternative with
          respect to four Energy Group Shares.
 
     (ii)
        The scaling down (if required) of elections for the Share Alternative
        shall be calculated in accordance with the following formula:

                where    X     is the scaled down number of Energy Group Shares (including
                               Energy Group Shares represented by Energy Group ADSs) on the
                               basis of which the entitlement of an accepting Energy Group
                               Shareholder to receive New Texas Utilities Shares under the
                               Share Alternative will be calculated;
                         N     is the number of Energy Group Shares (including Energy Group
                               Shares represented by Energy Group ADSs) in respect of which
                               such shareholder has elected for the Share Alternative;
                         A     is 20 per cent. of the fully diluted number of Energy Group
                               Shares (including Energy Group Shares represented by Energy
                               Group ADSs), as determined by TU Acquisitions;
                         B     is the total number of Energy Group Shares (including Energy
                               Group Shares represented by Energy Group ADSs) in respect of
                               which Energy Group Shareholders have elected for the Share
                               Alternative as at midnight (London time), 7.00 pm (New York
                               City time) on the date ten days after the Initial Closing
                               Date (as it may be extended); and
                         C     is the fully diluted number of Energy Group Shares
                               (including Energy Group Shares represented by Energy Group
                               ADSs), as determined by TU Acquisitions, less the total
                               number of Energy Group Shares (including Energy Group Shares
                               represented by Energy Group ADSs) for which valid
                               acceptances have been received as at midnight (London Time),
                               7.00 pm (New York City time) on the date ten days after the
                               Initial Closing Date (as it may be extended).
</TABLE>
 
(c)   The New Texas Utilities Shares will be issued free from all liens, charges
      and other encumbrances or other equitable interests. New Texas Utilities
      Shares will rank pari passu in all respects with existing shares of Texas
      Utilities Common Stock, including the right to receive in full all
      dividends, if any, and other distributions declared on such shares with a
      record date after the date of issuance of such shares.
 
(d)   No election for the Share Alternative will be valid unless both a valid
      acceptance of the Texas Utilities Offer and a valid election for the Share
      Alternative, duly completed in all respects and accompanied by, if
      appropriate, all relevant share certificates and/or other document(s) of
      title, are duly received by the time and date on which the Share
      Alternative closes.
 
(e)   If any acceptance of the Texas Utilities Offer which includes an election
      for the Share Alternative is not, or is not deemed to be, valid or
      complete in all respects at such time, such election shall for all
      purposes be void and the holder(s) of Energy Group Securities purporting
      to make such election shall not, for any purpose, be entitled to receive
      New Texas Utilities Shares under the Share Alternative, but any such
      acceptance which is otherwise valid shall be deemed to be an acceptance of
      the Texas Utilities Offer (without the Share Alternative) for the number
      of Energy Group Securities which are the subject of the acceptance and the
      relevant holder(s) of Energy Group Securities will, on the Texas Utilities
      Offer becoming unconditional in all respects, be entitled to receive such
      cash consideration as shall become due under the Texas Utilities Offer.
 
(f)   The Share Alternative will remain open for acceptance for as long as the
      Texas Utilities Offer remains open for acceptance. An election for the
      Share Alternative will be made on the terms and subject to the conditions
      set out in this document and in the relevant Acceptance Form.
 
(g)   Holders of Energy Group Securities who are entitled to receive New Texas
      Utilities Shares pursuant to the Texas Utilities Offer may take advantage
      of safekeeping services provided by Texas Utilities Shareholder Services
      ("Shareholder Services") with respect to such New Texas Utilities Shares.
                                      I-11
<PAGE>   46
 
      Unless the person entitled to such New Texas Utilities Shares elects to
      receive certificated securities, all New Texas Utilities Shares to which
      such person is entitled will be held by Shareholder Services or its
      nominee and credited to such person's account. There will be no charge for
      safekeeping of the New Texas Utilities Shares by Shareholder Services.
 
     An owner of New Texas Utilities Shares held by Shareholder Services may
     request Shareholder Services at any time to sell all or a portion of his or
     her New Texas Utilities Shares by delivering to Shareholder Services a
     written request. Shareholder Services will instruct an independent broker
     to sell such shares as soon as practicable after processing the request and
     will transmit to the owner the proceeds of the sale (less brokerage fees
     and commissions, any transfer taxes and a fee of $10 for each such
     transfer).
 
     Each owner of New Texas Utilities Shares held by Shareholder Services will
     receive a receipt for such New Texas Utilities Shares from Shareholder
     Services, together with information about other services provided by
     Shareholder Services, mailed as soon as practicable after the end of the
     Subsequent Offer Period. Thereafter, Shareholder Services will mail a
     quarterly statement of account to each owner of New Texas Utilities Shares
     held in safekeeping by Shareholder Services for such owner. Quarterly
     statements are the owner's record of the shares of Texas Utilities Common
     Stock held by Shareholder Services, including any sales or transfers
     thereof, and should be retained for tax purposes.
 
     Certificates for any number of whole New Texas Utilities Shares held by
     Shareholder Services for an owner will be issued at no charge upon the
     written request of such owner mailed to Shareholder Services. New Texas
     Utilities Shares held by Shareholder Services may not be pledged. Any owner
     who wishes to pledge such shares must request that certificates for the
     shares be issued in such owner's name.
 
     Cash dividends paid on New Texas Utilities Shares held by Shareholder
     Services will be paid by cheque mailed to the owner, subject to any
     required United States income tax withholding.

5  LOAN NOTE ALTERNATIVE
 
(a)  The Loan Note Alternative is conditional upon the Texas Utilities Offer
     becoming or being declared unconditional in all respects.
 
(b)  No election for the Loan Note Alternative will be valid unless both a valid
     acceptance of the Texas Utilities Offer and a valid election for the Loan
     Note Alternative, duly completed in all respects and accompanied by, if
     appropriate, all relevant share certificates and/or other document(s) of
     title, are duly received by the time and date on which the Loan Note
     Alternative closes.
 
(c)  If any acceptance of the Texas Utilities Offer which includes an election
     for the Loan Note Alternative is not, and is not deemed to be, valid or
     complete in all respects at such time, such election shall for all purposes
     be void and the holder(s) of Energy Group Shares purporting to make such
     election shall not, for any purpose, be entitled to receive the Loan Note
     Alternative, but any such acceptance which is otherwise valid shall be
     deemed to be an acceptance of the Texas Utilities Offer (without the Loan
     Note Alternative) for the number of Energy Group Shares which are the
     subject of the acceptance and the holder(s) of Energy Group Shares will, on
     the Texas Utilities Offer becoming unconditional in all respects, be
     entitled to receive the cash consideration due under the Texas Utilities
     Offer.
 
(d)  The Loan Note Alternative will remain open for acceptance for as long as
     the Texas Utilities Offer remains open for acceptance.

6  EFFECT OF ELECTIONS
 
(a)  The completion of Box 3 on the Form of Acceptance or of the Limited Share
     Election box in the Letter of Transmittal shall, subject to the other terms
     of the Texas Utilities Offer, be treated as an election for the Share
     Alternative summarised in paragraph 4 of the letter from Lehman Brothers
     and Merrill Lynch set out earlier in this Offer Document and described in
     paragraph 4 of Part B of Appendix I above and as an acknowledgement and
     agreement by the relevant holder of Energy Group Securities that:
 
     (i)   he shall release and discharge TU Acquisitions from any obligation
           pursuant to the Texas Utilities Offer to pay cash in respect of that
           part of his holding of Energy Group Securities in respect of which he
           is entitled to receive New Texas Utilities Shares (except any amount
           of L3.00 or over payable as referred to in (ii) below and/or in
           respect of a fractional entitlement to a New Texas Utilities Share)
           and accepts the undertaking of Texas Utilities to issue to him the
           New Texas Utilities Shares to which he is entitled pursuant to the
           Share Alternative;
 
     (ii)  to the extent that such holder's election for the Share Alternative 
           is scaled down (in the manner referred to in paragraph 4 of Part B of
           Appendix I above), such holder will, in relation to that part of his
           holding for which his election for the Share Alternative is
           unsuccessful, receive the cash consideration to which he is entitled,
           in respect of that part of his holding, under the Texas Utilities
           Offer as if he had not elected for the Share Alternative (other than
           any amount which, when aggregated with any fractional entitlement to
           a New Texas Utilities Share, is less than L3.00); and
 
     (iii) if the conditions to the Share Alternative referred to in paragraphs
           4(a)(ii) and (iii) of Part B of Appendix I above relating to the
           listing of New Texas Utilities Shares and the Registration Statement
           are not satisfied at the time the Texas Utilities Offer becomes or is
           declared unconditional in all respects, the Share Alternative will
           lapse and such holder will only be entitled to receive the cash
           consideration payable under the Texas Utilities Offer (and will be
           deemed not to have elected for the Share Alternative);
 
     and shall also constitute the acceptance by such holder of an offer to him
     by TU Acquisitions and Texas Utilities to enter into an agreement with TU
     Acquisitions and Texas Utilities to the effect that:
 
     (iv)  he shall release and discharge TU Acquisitions from any obligation
           pursuant to the Texas Utilities Offer to pay cash in respect of that
           part of his holding of Energy Group Securities in respect of which he
           is entitled to receive New Texas Utilities Shares (except any amount
           of L3.00 or over payable in respect of a fractional entitlement to a
           New Texas Utilities Share) and accepts the undertaking of Texas
           Utilities to issue to him the New Texas Utilities Shares to which he
           is entitled pursuant to the Share Alternative;
 
     (v)   Texas Utilities agrees to issue to such holder the New Texas 
           Utilities Shares to which such holder is entitled pursuant to the
           Share Alternative; and
 
     (vi)  TU Acquisitions accepts the release and discharge of its liability to
           pay cash consideration by such holder as specified in (iv) above and
           agrees to pay to Texas Utilities an amount equal to the amount of the
           cash consideration from the obligation to pay which such holder has
           agreed to release and discharge TU Acquisitions.
 
(b)  The insertion of a number in Box 4 on the Form of Acceptance shall, subject
     to the other terms of the Texas Utilities Offer, be treated in respect of
     the relevant number of Energy Group Shares as an election for the Loan Note
     Alternative described in paragraph 5 of this Part B of Appendix I above.
 
(c)  An election will not be valid unless the Acceptance Form is completed
     correctly in all respects and is received in accordance with paragraph 10
     ("Procedures for tendering Energy Group ADSs") or paragraph 11 ("Procedures
     for tendering Energy Group Shares") below.
 
(d)  To allow TU Acquisitions to pay interest on the Loan Notes without
     withholding US income tax, beneficial owners of Loan Notes must certify
     that they are not US Persons for the purposes of US federal income tax laws
     (see paragraph 13(b) of Appendix VIII below).
 
                                      I-13
<PAGE>   48
 
(e)  In the event that both Boxes 3 and 4 are completed on a Form of Acceptance,
     any election for the Loan Note Alternative will only be effective to the
     extent that the shareholder's election for the Share Alternative is scaled
     down (in the manner referred to in paragraph 4 of Part B of Appendix I
     above) so that there are a number of Energy Group Shares (the "residual
     number") in respect of which the relevant shareholder has accepted the
     Texas Utilities Offer but will not be entitled to receive New Texas
     Utilities Shares. If, in such circumstances the number inserted or deemed
     to be inserted in Box 4 on the Form of Acceptance is greater than the
     residual number, the election for the Loan Note Alternative will be treated
     as being made in respect of a number of Energy Group Shares equal to the
     residual number.
 
7  REVISIONS OF THE TEXAS UTILITIES OFFER, THE LOAN NOTE ALTERNATIVE AND/OR THE
   SHARE ALTERNATIVE
 
(a)  Although no revision of the Texas Utilities Offer is envisaged, if the
     Texas Utilities Offer (in its original or any previously revised form(s))
     is revised (either in its terms or Conditions or in the value or form of
     the consideration offered or otherwise) and any such revision represents,
     on the date on which such revision is announced (on such basis as Lehman
     Brothers and Merrill Lynch may consider appropriate) an improvement (or no
     diminution) in the value of the consideration under the Texas Utilities
     Offer as so revised compared with the value of the consideration previously
     offered, the benefit of the revised Texas Utilities Offer will, subject as
     provided in this paragraph 7 below, be made available to holders of Energy
     Group Securities who have accepted the Texas Utilities Offer in its
     original or any previously revised form(s) and not validly withdrawn such
     acceptance (hereinafter called a "Previous Acceptor"). The acceptance by or
     on behalf of a Previous Acceptor of the Texas Utilities Offer in its
     original or any previously revised form(s) shall, subject as provided in
     this paragraph 7 and in paragraph 10 or paragraph 11 of Part B of this
     Appendix I below, be deemed to be an acceptance of the Texas Utilities
     Offer as so revised and shall constitute the appointment of any director of
     TU Acquisitions or of Lehman Brothers and/or Merrill Lynch as his attorney
     and/or agent with authority to accept any such revised Texas Utilities
     Offer on behalf of such Previous Acceptor and to make such elections as
     those made by the Previous Acceptor in relation to the Texas Utilities
     Offer in the Acceptance Form previously executed by him or on his behalf
     and to execute on behalf of and in the name of such Previous Acceptor all
     such further documents and take such further actions (if any) as may be
     required to give effect to such acceptances and/or elections. In making any
     such acceptance or making any such election, the attorney and/or agent will
     take into account the nature of any previous acceptances and/or elections
     made by or on behalf of the Previous Acceptor and such other facts or
     matters as he may reasonably consider relevant.
 
(b)  The authorities conferred by paragraph 7(a) of Part B of this Appendix I
     above shall not be exercised by any director of TU Acquisitions or of
     Lehman Brothers and/or Merrill Lynch, as the case may be, if, as a result
     thereof, the Previous Acceptor would thereby receive less in cash than he
     would have received as a result of his acceptance of the Texas Utilities
     Offer (in its original or any previously revised form(s)) in the form in
     which it was originally accepted by him and the exercise of the powers of
     attorney so conferred by paragraph 7(a) of Part B of this Appendix I above
     of any such Previous Acceptor shall be ineffective to the extent that such
     Previous Acceptor shall lodge, within 14 calendar days of the posting of
     the document pursuant to which the improved consideration referred to in
     paragraph 7(a) of Part B of this Appendix I above is made available to
     holders of Energy Group Securities, an Acceptance Form validly accepting
     the Texas Utilities Offer in which he validly elects to receive the
     consideration receivable by him in some other manner than that set out in
     his original acceptance.
 
(c)  TU Acquisitions reserves the right (subject to paragraph 7(a) of this Part
     B of this Appendix I above) to treat an executed Acceptance Form relating
     to the Texas Utilities Offer (in its original or any previously revised
     form(s)) which is received (or dated) after the announcement or issue of
     the Texas Utilities Offer in any revised form as a valid acceptance and/or
     election of the revised Texas Utilities Offer and such acceptance shall
     constitute an authority in the terms of paragraph 7(a) of Part B of this
     Appendix I above, mutatis mutandis, on behalf of the relevant holder of
     Energy Group Securities.

8  GENERAL
 
(a)  If the Texas Utilities Offer lapses, pursuant to the City Code, neither TU
     Acquisitions nor any person acting or deemed to be acting in concert with
     TU Acquisitions for the purpose of the Texas Utilities Offer nor any of
     their respective affiliates may make an offer (whether inside or outside
     the United Kingdom) for Energy Group Securities for a period of one year
     following the date of such lapse, except with the consent of the Panel.
 
(b)  Except with the consent of the Panel, settlement of the consideration to
     which any holder of Energy Group Securities is entitled under the Texas
     Utilities Offer will be implemented in full in accordance with the terms of
     the Texas Utilities Offer without regard to any lien, right of set-off,
     counterclaim or other analogous right to which TU Acquisitions may
     otherwise be, or claim to be, entitled as against such holder of Energy
     Group Securities. Consideration due to a holder of Energy Group Securities
     who validly accepts the Texas Utilities Offer will (except with the consent
     of the Panel) be despatched not later than 14 calendar days after the later
     of the Initial Closing Date and the date of receipt of a valid and complete
     acceptance from such holder of Energy Group Securities. Cash consideration
     will be settled as described in paragraph 15 ("Settlement") below.
 
(c)  Any omission or failure to despatch this document, the Acceptance Form, any
     other document relating to the Texas Utilities Offer and/or any notice
     required to be despatched under the terms of the Texas Utilities Offer to,
     or any failure to receive the same by, any person to whom the Texas
     Utilities Offer is made or should be made shall not invalidate the Texas
     Utilities Offer in any way. Subject to the provisions of paragraph 9
     ("Overseas shareholders") below, the Texas Utilities Offer extends to any
     such persons to whom this document, the Acceptance Form, and/or any related
     offering document may not have been despatched or who may not receive such
     documents and such persons may collect copies of those documents from
     Lehman Brothers or Merrill Lynch.
 
(d)  All powers of attorney, appointment of agents and authorities on the terms
     conferred by or referred to in this Appendix I or in the Acceptance Form
     are given by way of security for the performance of the obligations of the
     holder of Energy Group Securities concerned and are irrevocable in
     accordance with section 4 of the Powers of Attorney Act 1971, except in the
     circumstances where the donor of such power of attorney or authority is
     entitled to withdraw his acceptance in accordance with paragraph 3 ("Rights
     of withdrawal") above and duly does so.
 
(e)  If all Conditions are satisfied, fulfilled or, where permitted, waived and
     TU Acquisitions acquires or contracts to acquire, pursuant to the Texas
     Utilities Offer or otherwise, at least 90 per cent. in value of the Energy
     Group Shares (including Energy Group Shares represented by Energy Group
     ADSs) to which the Texas Utilities Offer relates before the end of the
     period of four months beginning with the date of the Texas Utilities Offer,
     it will be entitled to and intends to acquire the remaining Energy Group
     Shares on the same terms as the Texas Utilities Offer pursuant to and
     subject to sections 428 to 430F (inclusive) of the Companies Act.
 
     Whether or not TU Acquisitions is in a position to effect the compulsory
     acquisition of any outstanding Energy Group Shares in accordance with the
     Companies Act as referred to above, and irrespective of the size of any
     outstanding minority in The Energy Group, TU Acquisitions intends to seek
     to procure, after the Texas Utilities Offer becomes or is declared
     unconditional, an application by The Energy Group to the London Stock
     Exchange for Energy Group Shares to be delisted and an application by The
     Energy Group to the NYSE for Energy Group ADSs to be delisted.
 
(f)  TU Acquisitions, Lehman Brothers and Merrill Lynch reserve the right to
     notify any matter, including the making of the Texas Utilities Offer, to
     all or any holders of Energy Group Securities with a registered address
     outside the United Kingdom and the United States, or whom TU Acquisitions
     knows to be a custodian, trustee or nominee holding Energy Group Securities
     for persons in Canada, Australia, or Japan, by announcement in the United
     Kingdom to the London Stock Exchange and in the United States to the Dow
     Jones News Service or in any other appropriate manner, or by paid
     advertisement in a newspaper published and circulated in the United Kingdom
     and the United States, in which event such
 
                                      I-15
<PAGE>   50
 
     notice will be deemed to have been sufficiently given, notwithstanding any
     failure by any such holders of Energy Group Securities to receive or see
     such notice. All references in this document to notice in writing by or on
     behalf of TU Acquisitions will be construed accordingly. No such document
     will be sent to an address in Canada, Australia or Japan.
 
(g)  The Texas Utilities Offer is being extended by means of an advertisement to
     be inserted in the Financial Times (United Kingdom version only) on 10
     March 1998 to all persons to whom this document or an Acceptance Form may
     not be despatched (or by whom such documents may not be received) who hold
     or are entitled to have allotted or issued to them Energy Group Securities.
 
(h)  The terms, provisions, instructions and authorities contained in the
     Acceptance Form constitute part of the terms of the Texas Utilities Offer.
     Words and expressions defined in this document have the same meanings when
     used in the Acceptance Form, unless the context otherwise requires.
 
(i)  References to a holder of Energy Group Securities include references to the
     person or persons executing any Acceptance Form and in the event of more
     than one person executing an Acceptance Form, such references will apply to
     them jointly and severally.
 
9  OVERSEAS SHAREHOLDERS
 
(a)  The making of the Texas Utilities Offer in, or to certain persons who are
     citizens, residents or nationals of, jurisdictions outside the United
     Kingdom or the United States (and the availability of Loan Notes and/or New
     Texas Utilities Shares to such persons and, in the case of Loan Notes, to
     citizens or residents of the United States) may be prohibited or affected
     by the laws of the relevant overseas jurisdiction. Holders of Energy Group
     Securities who are citizens, residents or nationals of jurisdictions
     outside the United Kingdom and the United States (and, in the case of Loan
     Notes, the United Kingdom only) should inform themselves about and observe
     any applicable legal requirements. It is the responsibility of any such
     holder of Energy Group Securities wishing to accept the Texas Utilities
     Offer, the Share Alternative or the Loan Note Alternative to satisfy
     himself as to the full observance of the laws of the relevant jurisdiction
     in connection therewith, including the obtaining of any governmental,
     exchange control or other consents which may be required, compliance with
     other necessary formalities and the payment of any issue, transfer or other
     taxes or duties in such jurisdiction. Any such holder of Energy Group
     Securities will also be responsible for payment of any issue, transfer or
     other taxes or duties or other requisite payments due in such jurisdiction
     by whomsoever payable and each of TU Acquisitions and Lehman Brothers,
     Merrill Lynch and any person acting on their behalf shall be entitled to be
     fully indemnified and held harmless by such holder of Energy Group
     Securities for any issue, transfer or other taxes or duties as TU
     Acquisitions, Lehman Brothers, Merrill Lynch or such person may be required
     to pay.
 
(b)  In particular, the Texas Utilities Offer is not being made, directly or
     indirectly, in or into Canada, Australia or Japan, or by use of the mails
     or any means or instrumentality (including, without limitation, facsimile
     transmission, telex or telephone) of interstate or foreign commerce of, or
     any facilities of a national securities exchange of, any of these
     jurisdictions. Accordingly, copies of this document, the Acceptance Form
     and any related offer documents are not being mailed or otherwise
     distributed or sent in or into Canada, Australia or Japan. Persons
     receiving such documents (including, without limitation, custodians,
     nominees and trustees) must not distribute, send or mail them in, into or
     from Canada, Australia or Japan or use any such means, instrumentality or
     facilities in connection with the Texas Utilities Offer, and doing so may
     render invalid any related purported acceptance of the Texas Utilities
     Offer. Persons wishing to accept the Texas Utilities Offer must not use the
     Canadian, Australian or Japanese mails or any such means, instrumentality
     or facilities for any purpose directly or indirectly related to acceptance
     of the Texas Utilities Offer. Envelopes containing the Acceptance Form must
     not be postmarked in Canada, Australia or Japan or otherwise despatched
     from these jurisdictions and all acceptors must provide addresses outside
     Canada, Australia and Japan for the receipt of the consideration to which
     they are entitled under the Texas Utilities Offer and which is despatched
     by post or for the
 
                                      I-16
<PAGE>   51
 
     return of the Acceptance Form and (in relation to Energy Group Shares in
     certificated form) any Energy Group Share certificate(s) and/or other
     document(s) of title.
 
(c)  The provisions of this paragraph 9 and/or other terms of the Texas
     Utilities Offer relating to overseas holders of Energy Group Securities may
     be waived, varied or modified as regards specific holders of Energy Group
     Securities or on a general basis by TU Acquisitions in its absolute
     discretion. References in this paragraph 9 to holders of Energy Group
     Securities shall include references to the person or persons executing an
     Acceptance Form and, in the event of more than one person executing an
     Acceptance Form, the provisions of this paragraph 9 shall apply to them
     jointly and severally.
 
(d)  If, pursuant to the Texas Utilities Offer, any New Texas Utilities Shares
     would otherwise be issued to any person(s) whom TU Acquisitions believes
     would be unable to give the representation and warranty set out in
     paragraph 12(l) of Part B of this Appendix I below, then such person(s)
     shall be deemed to have given an authority to TU Acquisitions and its
     agents, as agents and/or attorneys of such person(s) in respect of the New
     Texas Utilities Shares to which such person(s) thereby become(s) entitled:
     (i) to sell such shares on behalf of such holder in the market within 21
     days of such shares being allotted, (ii) to receive the certificate(s)
     and/or other document(s) of title therefor and to execute instrument(s) of
     transfer in respect of such shares, and (iii) to remit the net proceeds of
     such sale(s) (after deducting therefrom the expenses of sale) as soon as
     reasonably practicable to the person or agent whose name and address is set
     out in the relevant box in the Acceptance Form or, if no name is set out,
     to the first-named holder at his registered address. Neither TU
     Acquisitions nor any person acting on behalf of it shall have any liability
     to any person for any loss or alleged loss arising from the price, timing
     or manner of any sale made pursuant to the authority set out above or
     otherwise in connection therewith.
 
(e)  The New Texas Utilities Shares to be issued pursuant to the Share
     Alternative will not be the subject of a prospectus under the securities
     laws of any province of Canada. In addition, no steps have been taken, nor
     will be taken, to enable the New Texas Utilities Shares to be offered in
     Japan in compliance with applicable securities laws of Japan and no
     prospectus in relation to the New Texas Utilities Shares has been, or will
     be, lodged with or registered by the Australian Securities Commission, nor
     will the New Texas Utilities Shares be registered under any relevant
     securities laws of any other country. TU Acquisitions will not authorise
     the delivery of any document(s) of title in respect of any New Texas
     Utilities Shares falling to be allotted pursuant to the Texas Utilities
     Offer to any address in Canada, Australia or Japan or to any person who is,
     or whom TU Acquisitions has reason to believe is a person in Canada,
     Australia or Japan or who, by completing Box 9 of the Form of Acceptance or
     otherwise, does not give the warranty set out in paragraph 12(l) of this
     Part B of Appendix I. Any holder of Energy Group Securities accepting the
     Texas Utilities Offer who is a person in Canada, Australia or Japan or who
     does not give such warranty shall be deemed not to have accepted the Share
     Alternative.
 
(f)  The Loan Notes to be issued pursuant to the Loan Note Alternative have not
     been, and will not be, registered under the Securities Act or under any
     relevant securities law of any state or district of the United States and
     will not be the subject of a prospectus under the securities laws of any
     province of Canada. In addition, no steps have been taken, or will be
     taken, to enable the Loan Notes to be offered in Japan in compliance with
     applicable securities laws of Japan and no prospectus in relation to the
     Loan Notes has been, or will be, lodged with or registered by the
     Australian Securities Commission, nor will the Loan Notes be registered
     under any relevant securities laws of any other country. TU Acquisitions
     will not authorise the delivery of any document(s) of title in respect of
     any Loan Notes falling to be allotted pursuant to the Texas Utilities Offer
     to any address in the United States, Canada, Australia or Japan or to any
     person who is, or whom TU Acquisitions has reason to believe is, a US
     Person or a person in Canada, Australia or Japan or who, by completing Box
     9 of the Form of Acceptance or otherwise, does not give the warranty set
     out in paragraph 12(l) of this Part B of Appendix I. Any holder of Energy
     Group Securities accepting the Texas Utilities Offer who is a US Person or
     a person in Canada, Australia or Japan or who does not give such warranty
     shall be deemed not to have accepted the Loan Note Alternative.

10  PROCEDURES FOR TENDERING ENERGY GROUP ADSS
 
(a)  If you are a holder of Energy Group ADSs evidenced by Energy Groups ADRs,
     you will have also received a Letter of Transmittal and Notice of
     Guaranteed Delivery for use in connection with the Texas Utilities Offer.
     This section should be read together with the instructions on the Letter of
     Transmittal. The provisions of this section shall be deemed to be
     incorporated in, and form a part of, the relevant Letter of Transmittal.
     The instructions printed on the relevant Letter of Transmittal shall be
     deemed to form part of the terms of the Texas Utilities Offer.
 
(b)  For a holder of Energy Group ADSs evidenced by Energy Group ADRs to tender
     such Energy Group ADSs validly pursuant to the Texas Utilities Offer,
     either:
 
     (i)  a properly completed and duly executed Letter of Transmittal, together
          with any required signature guarantees and any other required
          documents (or Agent's Message in the case of book-entry transfers),
          must be received by the US Depositary at one of its addresses set
          forth on the back cover of this document and the Energy Group ADRs
          evidencing such Energy Group ADSs must be either received by the US
          Depositary at one of such addresses or delivered pursuant to the
          procedures for book-entry transfers set out below (and a confirmation
          of receipt of such transfer received by the US Depositary); or
 
     (ii) such holder must comply with the "Guaranteed Delivery Procedures" (as
          set forth in paragraph 10(h) below).
 
The Texas Utilities Offer in respect of Energy Group ADSs evidenced by Energy
Group ADRs shall be validly accepted by delivery of a Letter of Transmittal (or
Agent's Message in case of book-entry transfers), the relevant Energy Group ADRs
evidencing Energy Group ADSs and other required documents to the US Depositary
by holders of Energy Group ADSs (without any further action by the US
Depositary), subject to the terms and conditions set out in the Letter of
Transmittal. The acceptance of the Texas Utilities Offer by a tendering holder
of Energy Group ADSs evidenced by Energy Group ADRs pursuant to the procedures
described above, subject to the withdrawal rights described below, will be
deemed to constitute a binding agreement between such tendering holder of Energy
Group ADSs and TU Acquisitions upon the terms and subject to the Conditions of
the Texas Utilities Offer. IF AN ENERGY GROUP ADR EVIDENCING AN ENERGY GROUP ADS
HAS BEEN TENDERED BY A HOLDER OF ENERGY GROUP ADSS, THE ENERGY GROUP SHARES
REPRESENTED BY SUCH ENERGY GROUP ADSS MAY NOT BE TENDERED INDEPENDENTLY. A
LETTER OF TRANSMITTAL AND OTHER REQUIRED DOCUMENTS CONTAINED IN AN ENVELOPE
POSTMARKED IN CANADA, AUSTRALIA OR JAPAN OR OTHERWISE APPEARING TO TU
ACQUISITIONS OR ITS AGENTS TO HAVE BEEN SENT FROM CANADA, AUSTRALIA OR JAPAN MAY
BE REJECTED AS INVALID.
 
(c) BOOK-ENTRY TRANSFER
 
     The US Depositary will establish an account at the Book-Entry Transfer
     Facilities with respect to interests in Energy Group ADSs evidenced by
     Energy Group ADRs held in book-entry form for the purposes of the Texas
     Utilities Offer within two Business Days from the date of this document.
     Any financial institution that is a participant in any of the Book-Entry
     Transfer Facility's systems may make book-entry delivery of interests
     Energy Group ADSs by causing a Book-Entry Transfer Facility to transfer
     such interests in Energy Group ADSs into the US Depositary's account at
     such Book-Entry Transfer Facility in accordance with that Book-Entry
     Transfer Facility's procedure for such transfer. Although delivery of
     interests in Energy Group ADSs evidenced by Energy Group ADRs may be
     effected through book-entry transfer into the US Depositary's account at a
     Book-Entry Transfer Facility, either:
 
     (i)  the Letter of Transmittal, properly completed and duly executed,
          together with any required signature guarantees; or
 
     (ii) an Agent's Message (as defined below),
 
     and, in either case, any other required documents must in any case be
     transmitted to, and received by, the US Depositary at one of its addresses
     set forth on the back cover of this document before Energy Group ADSs
     evidenced by Energy Group ADRs will be either counted as a valid acceptance
     or purchased, or
 
                                      I-18
<PAGE>   53
 
     such holder must comply with the Guaranteed Delivery Procedures described
     below. The term "Agent's Message" means a message transmitted by a
     Book-Entry Transfer Facility to, and received by, the US Depositary and
     forming a part of a Book-Entry Confirmation that states that such
     Book-Entry Transfer Facility has received an express acknowledgement from
     the participant in such Book-Entry Transfer Facility tendering the
     interests in Energy Group ADSs that such participant has received and
     agrees to be bound by the terms of the Letter of Transmittal. Delivery of
     documents to a Book-Entry Transfer Facility does not constitute delivery to
     the US Depositary.
 
(d)  METHOD OF DELIVERY
 
     The method of delivery of Energy Group ADRs, the Letters of Transmittal and
     all other required documents is at the option and risk of the tendering
     holder of Energy Group ADSs. Energy Group ADSs will be deemed delivered
     only when the Energy Group ADRs representing such Energy Group ADSs are
     actually received by the US Depositary (including in the case of a
     book-entry transfer, by Book-Entry Confirmation). If delivery is by mail,
     registered mail with return receipt requested, properly insured, is
     recommended. In all cases, sufficient time should be allowed to ensure
     timely delivery. No acknowledgement of receipt of any Letter of Transmittal
     or other required documents will be given by, or on behalf of, TU
     Acquisitions.
 
(e)  SIGNATURE REQUESTS
 
     No signature guarantee is required on the Letter of Transmittal if:
 
     (i)  the Letter of Transmittal is signed by the registered holder of the
          Energy Group ADSs tendered therewith and such registered holder has
          not completed either the Box entitled "Special Payment Instructions"
          or the Box entitled "Special Delivery Instructions" or the box
          entitled "Special Texas Utilities Common Stock Instructions" in the
          Letter of Transmittal; or
 
     (ii) such Energy Group ADSs are tendered for the account of an Eligible
          Institution.
 
     In all other cases all signatures on Letters of Transmittal must be
     guaranteed by an Eligible Institution. See Instruction 1 on the Letter of
     Transmittal.
 
(f)  ENERGY GROUP ADSS AND ADRS
 
     If the Energy Group ADSs are registered in the name of a person other than
     the person who signs the Letter of Transmittal, then the tendered Energy
     Group ADRs must be endorsed or accompanied by appropriate stock powers,
     signed exactly as the name or names of the registered owner or owners
     appear on the Energy Group ADRs, with the signatures on the Energy Group
     ADRs or stock powers guaranteed as aforesaid. See Instructions 1 and 5 on
     the Letter of Transmittal.
 
(g)  PARTIAL ACCEPTANCES
 
     If fewer than all of the Energy Group ADSs evidenced by any Energy Group
     ADRs delivered to the US Depositary are to be tendered, the holder thereof
     should so indicate in the Letter of Transmittal by filling in the number of
     Energy Group ADSs which are to be tendered in the box entitled "Number of
     Energy Group ADSs Tendered". In such case, a new Energy Group ADR for the
     remainder of the Energy Group ADSs represented by the former Energy Group
     ADR will be sent to the person(s) signing such Letter of Transmittal (or
     delivered as such person properly indicates thereon) as promptly as
     practicable following the date the tendered Energy Group ADSs are
     purchased. All Energy Group ADSs delivered to the US Depositary will be
     deemed to have been tendered unless otherwise indicated. See Instruction 4
     to the Letter of Transmittal. In the case of partial tenders, Energy Group
     ADSs not tendered will not be reissued to a person other than the
     registered holder.
 
(h)  GUARANTEED DELIVERY PROCEDURES
 
(i)  If a holder of Energy Group ADSs evidenced by Energy Group ADRs desires to
     tender Energy Group ADSs pursuant to the Texas Utilities Offer and the
     Energy Group ADRs evidencing such Energy Group ADSs are not immediately
     available or the procedures for book-entry transfer cannot be completed on
     a timely basis, or if time will not permit all required documents to reach
     the US Depositary prior to the
 
                                      I-19
<PAGE>   54
 
     expiry of the Subsequent Offer Period, such holder's tender of Energy Group
     ADSs may be effected if all the following conditions are met (the
     "Guaranteed Delivery Procedures"):
 
        (aa)     such tender is made by or through an Eligible Institution;
 
        (bb)     a properly completed and duly executed Notice of Guaranteed
                 Delivery substantially in the form provided by TU Acquisitions
                 is received by the US Depositary, as provided below, prior to
                 the expiry of the Subsequent Offer Period; and
 
        (cc)     the Energy Group ADRs evidencing all tendered Energy Group ADSs
                 (or, in the case of interests in Energy Group ADSs held in
                 book-entry form, timely confirmation of the book-entry transfer
                 of such interests in Energy Group ADSs into the US Depositary's
                 account at a Book-Entry Transfer Facility as described above),
                 together with a properly completed and duly executed Letter of
                 Transmittal with any required signature guarantees and any
                 other documents required by the Letter of Transmittal, are
                 received by the US Depositary within three Business Days after
                 the date of execution of such Notice of Guaranteed Delivery.
 
     (ii)  The Notice of Guaranteed Delivery may be delivered by hand or mailed
           to the US Depositary and must include a signature guarantee by an
           Eligible Institution in the form set out in such Notice of Guaranteed
           Delivery.
 
     (iii) Receipt of a Notice of Guaranteed Delivery will not be treated as a
           valid acceptance for the purpose of satisfying the Acceptance
           Condition. To be counted towards satisfaction of this requirement,
           Energy Group ADRs evidencing Energy Group ADSs referred to in the
           Notice of Guaranteed Delivery must, prior to the Initial Closing
           Date, be received by the US Depositary (or, in the case of interests
           in Energy Group ADSs evidenced by Energy Group ADRs held in book-
           entry form, timely confirmation of a book-entry transfer of such
           interests in Energy Group ADSs into the US Depositary's account at a
           Book-Entry Transfer Facility pursuant to the procedure set out
           above), together with a duly executed Letter of Transmittal with any
           required signature guarantees (or, in the case of a book-entry
           transfer, an Agent's Message) and any other required documents.
 
(i)  OTHER REQUIREMENTS
 
     By executing the Letter of Transmittal as set out above, the tendering
     holder of Energy Group ADSs evidenced by Energy Group ADRs will agree that
     effective from and after the date all Conditions are satisfied or, where

          deemed to have been accepted and any other rights and privileges

          requisition a general meeting of The Energy Group or of any class of
          its shareholders; and
 
     (ii) the execution of the Letter of Transmittal and its delivery to the US
          Depositary (or delivery of an Agent's message to the US Depositary)

        (aa)    an authority to The Energy Group or its agents from the
                tendering holder of Energy Group ADSs to send any notice,
                circular, warrant, document or other communication, which may be
                sent to him as a holder of Energy Group ADSs, to TU Acquisitions
                at its registered office;
 
        (bb)    an authority to TU Acquisitions or its agent to sign any consent
                to short notice of a general meeting or separate class meeting

                and to exercise the votes attaching to such Energy Group ADSs on
                the holders' behalf; and
 
        (cc)    the agreement of the tendering holder of Energy Group ADSs not
                to exercise any of such rights without the consent of TU
                Acquisitions and the irrevocable undertaking of the tendering

(j)  If the Texas Utilities Offer lapses, all documents tendered will be
     returned within 14 calendar days thereafter at the risk of the holder of
     Energy Group Securities concerned.
 
(k)  If you are a holder of Energy Group ADSs and are in any doubt about the
     procedure for acceptance, please telephone the Information Agent on (800)
     848-3416 (in the US), 0171-600-5005 (in Europe) or (212) 269-5550 (outside
     the US and Europe).
 
11  PROCEDURES FOR TENDERING ENERGY GROUP SHARES
 
(a)  Holders of Energy Group Shares will have received with this document a Form
     of Acceptance. This section should be read together with the Form of
     Acceptance. The provisions of this section shall be deemed to be
     incorporated in, and to form a part of, the Form of Acceptance. The
     instructions printed on the Form of Acceptance shall be deemed to form part
     of the terms of the Texas Utilities Offer.
 
     If a holder of Energy Group Shares holds Energy Group Shares in both
     certificated and uncertificated form, he should complete a separate Form of
     Acceptance for each holding. Similarly, such holder should complete a
     separate Form of Acceptance for Energy Group Shares held in uncertificated
     form, but under different member account IDs, and for Energy Group Shares
     held in certificated form, but under different designations.
 
(b)  To accept the Texas Utilities Offer, any holder of Energy Group Shares,
     including any person in the US who holds Energy Group Shares, wishing to
     accept the Texas Utilities Offer in respect of all or any portion of such
     holder's Energy Group Shares, should complete Box 1 and, if such holder's
     Energy Group Shares are in CREST, Box 8, and sign Box 7 on the Form of
     Acceptance in accordance with the instructions printed on it. All holders
     of Energy Group Shares who are individuals should sign the Form of
     Acceptance in the presence of a witness who should also sign Box 7 in
     accordance with the instructions printed on it. Unless witnessed, an
     acceptance will not be valid.
 
(c)  An accepting holder of Energy Group Shares should return the completed,
     signed and witnessed Form of Acceptance, whether or not such Energy Group
     Shares are in CREST, to the United Kingdom Receiving Agent or US
     Depositary. The completed Form of Acceptance, together, if such holder's
     Energy Group Shares are in certificated form, with his share certificate(s)
     and/or other document(s) of title, must be lodged with the United Kingdom
     Receiving Agent or the US Depositary, as soon as possible, but in any event
     so as to arrive not later than 10.00 pm (London time), 5.00 pm (New York
     City time) on 7 April 1998. If you have any questions as to how to complete
     the Form of Acceptance, please contact the United Kingdom Receiving Agent
     on 0117 937 0672 or the US Depositary on (888) 460-7637.
 
     A person in the US who holds Energy Group Shares may submit the Form of
     Acceptance, together with his share certificate(s) and/or other document(s)
     of title, to the US Depositary, who will receive such Form(s) of Acceptance
     and certificate(s) and/or other document(s) of title on behalf of the
     United Kingdom Receiving Agent. A Form of Acceptance contained in an
     envelope postmarked Canada, Japan or Australia or otherwise appearing to TU
     Acquisitions or its agents to have been sent from Canada, Japan or
     Australia may be rejected as invalid.
 
(d)  If Energy Group Shares are in uncertificated form, the holder should insert
     in Box 8 of the Form of Acceptance the participant ID and member account ID
     under which such Energy Group Shares are held by him in CREST and otherwise
     complete and return the Form of Acceptance as described above. In addition,
     such holder should take (or procure to be taken) the action set out below
     to transfer the Energy Group Shares in respect of which he wishes to accept
     the Texas Utilities Offer to an escrow balance, specifying The Royal Bank
     of Scotland plc (in its capacity as a CREST participant under the
     participant ID referred to below) as the escrow agent, as soon as possible
     and in any event so that the transfer to escrow settles not later than
     10.00 pm (London time), 5.00 pm (New York City time) on 7 April 1998.
 
                                      I-21
<PAGE>   56
 
(e)  If the holder of such Energy Group Shares is a CREST sponsored member, he
     should refer to his CREST sponsor before taking any action. Such holder's
     sponsor will be able to confirm details of his participant ID and the
     member account ID under which his Energy Group Shares are held. In
     addition, only his CREST sponsor will be able to send the TTE Instruction
     to CRESTCo in relation to his Energy Group Shares.
 
(f)  The holder of such Energy Group Shares in uncertificated form should send
     (or, if he is a CREST sponsored member, procure that his CREST sponsor
     sends) a TTE Instruction to CRESTCo which must be properly authenticated in
     accordance with CRESTCo's specifications and which must contain, in
     addition to the other information that is required for a TTE Instruction to
     settle in CREST, the following details:
 
     (i)    the number of Energy Group Shares to be transferred to an escrow
            balance;
 
     (ii)   the member account ID of such holder of Energy Group Shares. This
            must be the same member account ID as the member account ID that is
            inserted in Box 8 of the Form of Acceptance;
 
     (iii)  the participant ID of such holder of Energy Group Shares. This must
            be in the same participant ID as the participant ID that is inserted
            in Box 8 of the Form of Acceptance;
 
     (iv)   the participant ID of the escrow agent (the United Kingdom Receiving
            Agent in its capacity as a CREST Receiving Agent). This is RA75;
 
     (v)    the member account ID of the escrow agent. This is ENERGY;
 
     (vi)   the Form of Acceptance Reference Number. This is the Form of
            Acceptance Reference Number that appears on page 3 of the Form of
            Acceptance. This Reference Number should be inserted in the first
            eight characters of the shared note field on the TTE Instruction.
            Such insertion will enable the United Kingdom Receiving Agent to
            match the transfer to escrow to your Form of Acceptance. The holder
            of such shares should keep a separate record of this Form of
            Acceptance Reference Number for future reference;
 
     (vii)  the Intended Settlement Date. This should be as soon as possible and
            in any event not later than 7 April 1998;
 
     (viii) the Corporate Action Number for the Texas Utilities Offer. This is
            5.
 
(g)  After settlement of the TTE Instruction, such holder of Energy Group Shares
     will not be able to access the Energy Group Shares concerned in CREST for
     any transaction or charging purposes. If the Conditions are satisfied,
     fulfilled or, where permitted, waived, the escrow agent will transfer the
     Energy Group Shares concerned to itself in accordance with paragraph 12(d)
     of this Part B of Appendix I below.
 
(h)  Such holder of Energy Group Shares is recommended to refer to the CREST
     Manual published by CRESTCo for further information on the CREST procedures
     outlined above. For ease of processing, such holder is requested, wherever
     possible, to ensure that a Form of Acceptance relates to only one transfer
     to escrow.
 
(i)  If no Form of Acceptance Reference Number, or an incorrect Form of
     Acceptance Reference Number, is included on the TTE Instruction, TU
     Acquisitions may treat any amount of Energy Group Shares transferred to an
     escrow balance in favour of the escrow agent specified above from the
     participant ID and member account ID identified in the TTE Instruction as
     relating to any Form(s) of Acceptance which relate(s) to the same member
     account ID and participant ID (up to the amount of Energy Group Shares
     inserted or deemed to be inserted on the Form(s) of Acceptance concerned).
 
(j)  Such holder of Energy Group Shares should note that CRESTCo does not make
     available special procedures, in CREST, for any particular corporate
     action. Normal system timings and limitations will therefore apply in
     connection with a TTE Instruction and its settlement. Such holder should
     therefore ensure that all necessary action is taken by him (or by his CREST
     sponsor) to enable a TTE Instruction relating to his Energy Group Shares to
     settle prior to 10.00 pm (London time), 5.00 pm (New York City
 
                                      I-22
<PAGE>   57
 
     time) on 7 April 1998. In this connection such holder is referred in
     particular to those sections of the CREST Manual concerning practical
     limitations of the CREST system and timings.
 
(k)  TU Acquisitions will make an appropriate announcement if any of the details
     contained in this paragraph 11 alter for any reason.
 
(l)  Normal CREST procedures (including timings) apply in relation to any Energy
     Group Shares that are, or are to be, converted from uncertificated to
     certificated form, or from certificated to uncertificated form, during the
     course of the Texas Utilities Offer (whether any such conversion arises as
     a result of a transfer of Energy Group Shares or otherwise). Holders of
     Energy Group Shares who are proposing so to convert any Energy Group Shares
     are recommended to ensure that the conversion procedures are implemented in
     sufficient time to enable the person holding or acquiring the Energy Group
     Shares as a result of the conversion to take all necessary steps in
     connection with an acceptance of the Texas Utilities Offer (in particular,
     as regards delivery of share certificate(s) or other documents of title or
     transfers to an escrow balance as described above) prior to 10.00 pm
     (London time), 5.00 pm (New York City time) on 7 April 1998.
 
(m)  If the share certificate(s) and/or other document(s) of title is/are not
     readily available or is/are lost, the Form of Acceptance should
     nevertheless be completed, signed and returned as stated above to the
     United Kingdom Receiving Agent or the US Depositary so as to be received as
     soon as possible, but in any event no later than 10.00 pm (London time),
     5.00 pm (New York City time) on 7 April 1998 together with any share
     certificate(s) and/or other document(s) of title that is/are available,
     accompanied by a letter stating that the balance will follow or that one or
     more share certificate(s) and/or other document(s) of title have been lost
     and the certificate(s) and/or other document(s) of title should be
     forwarded as soon as possible thereafter. If the share certificate(s)
     and/or other document(s) of title are lost, the accepting holder should
     request the registrar of The Energy Group (Lloyds Bank Registrars, The
     Causeway, Goring-by-Sea, Worthing, West Sussex BN99 6DA) to send him a
     letter of indemnity for completion in accordance with the instructions
     given. When completed the letter of indemnity must be lodged with the
     United Kingdom Receiving Agent or the US Depositary, in accordance with
     instructions given, in support of the Form of Acceptance.
 
(n)  Subject to the City Code, TU Acquisitions reserves the right to treat as
     valid in whole or in part any acceptance of the Texas Utilities Offer which
     is not entirely in order or in the correct form or which is not accompanied
     by (as applicable) the relevant transfer to escrow or the relevant share
     certificate(s) and/or other document(s) of title or which is received by it
     at a place or places other than as set out in this document or the
     Acceptance Forms. In that event, the consideration under the Texas
     Utilities Offer will be despatched only when the acceptance is entirely in
     order and (as applicable) the relevant transfer to escrow or the relevant
     share certificate(s) and/or document(s) of title or indemnity satisfactory
     to TU Acquisitions has/have been received.
 
(o)  If the Texas Utilities Offer lapses, all documents lodged for acceptance
     will be returned within 14 calendar days thereafter at the risk of the
     holder of Energy Group Shares concerned.
 
(p)  No acknowledgement of receipt of any Form of Acceptance, share certificates
     and/or other documents(s) of title will be given by, or on behalf of TU
     Acquisitions. The method of delivery of share certificate(s) and/or other
     document(s) of title for Energy Group Shares and all other required
     documents is at the option and risk of the accepting holder of Energy Group
     Shares. In all cases, sufficient time should be allowed to ensure timely
     delivery and in any event to ensure delivery by 10.00 pm (London time),
     5.00 pm (New York City time) on 7 April 1998.
 
(q)  Any holder of Energy Group Shares who is in any doubt as to the procedure
     for acceptance should contact the United Kingdom Receiving Agent by
     telephone on 0117 937 0672. Such holder is also reminded that, if he is a
     CREST sponsored member, he should contact his CREST Sponsor before taking
     any action.

     paragraph 12(a)(iv) above, the irrevocable appointment of any director of,
     or other person nominated by, TU Acquisitions to act on its behalf as such
     holder's attorney and agent ("attorney"), and an irrevocable instruction to
     the attorney, to complete and execute all or any forms of transfer and/or

           TU Acquisitions or its agents may direct) by means of CREST all or
           any of the Relevant Energy Group Shares (as defined below) (but not
           exceeding the number of Energy Group Shares in respect of which the
           Texas Utilities Offer is accepted or deemed to be accepted);
 
     (ii)  if the Conditions are not satisfied, fulfilled or, where permitted,
           waived, to give instructions to CRESTCo, immediately after the
           lapsing of the Texas Utilities Offer (or within such longer period as
           the Panel may permit, not exceeding 14 days of the lapsing of the
           Texas Utilities Offer), to
 
                                      I-24
<PAGE>   59
           transfer all Relevant Energy Group Shares to the original available
           balance of the accepting holder of Energy Group Shares. "Relevant
           Energy Group Shares" means Energy Group Shares in uncertificated form
           and in respect of which a transfer or transfers to escrow has or have
           been effected pursuant to the procedures described in paragraphs
           11(d) to 11(l) of this Part B of Appendix I above and where the
           transfer(s) to escrow was or were made in respect of Energy Group
           Shares held under the same member account ID and participant ID as
           the member account ID and participant ID relating to the Form of
           Acceptance concerned (but irrespective of whether or not any Form of
           Acceptance Reference Number, or a Form of Acceptance Reference Number
           corresponding to that appearing on the Form of Acceptance concerned,
           was included in the TTE Instruction concerned);
 
     (iii) to The Energy Group or its agents to procure the registration of the
           transfer of the Energy Group Shares in certificated form pursuant to
           the Texas Utilities Offer and the delivery of the share

           to TU Acquisitions or as it may direct;
 
     (iv)  if the Energy Group Shares concerned are in certificated form, or if
           either of the provisos to sub-paragraph (v) of this paragraph 12(d)
           apply, to TU Acquisitions or its agents to procure the despatch by
           post (or by such other methods as may be approved by the Panel) of a
           cheque (in the case of a pounds sterling amount, drawn on a branch of
           a United Kingdom clearing bank) for any cash to which an accepting
           Energy Group Shareholder is entitled, at the risk of such
           shareholder, to the person or agent whose name and address outside
           Canada, Australia and Japan is set out in Box 10 of the Form of
           Acceptance, or if no name and address is set out in Box 10, to the
           first-named holder at his registered address outside Canada,
           Australia or Japan as set out in Box 2 (or, if applicable, Box 6) on
           the Form of Acceptance together with a cheque for any cash payable to
           such holder of Energy Group Shares in respect of fractional
           entitlements;
 
     (v)   if the Energy Group Shares concerned are in uncertificated form, to 
           TU Acquisitions or its agents to procure the creation of an assured
           payment obligation in favour of the holder of Energy Group Shares'
           payment bank in accordance with the CREST assured payment
           arrangements in respect of the cash consideration to which such
           shareholder is entitled, provided that (aa) TU Acquisitions may (if,
           for any reason, it wishes to do so) determine that all or any part of
           any such cash consideration shall be paid by cheque despatched by
           post and (bb) if the Energy Group Shareholder concerned is a CREST
           member whose registered address is in Canada, Australia or Japan, any
           cash consideration to which such shareholder is entitled shall be
           paid by cheque despatched by post, and in either of such cases,
           sub-paragraph (iii) of this paragraph 12(d) shall apply;
 
     (vi)  to TU Acquisitions or its agent(s) to record and act upon any
           instructions with regard to payment or notices which have been
           recorded in the records of The Energy Group in respect of such holder
           of Energy Group Shares as if such instructions had been given in
           respect of his entitlement to Loan Notes (if any); and
 
     (vii) to TU Acquisition or its agent(s) to procure that the name of such
           holder of Energy Group Shares is entered on the share register of
           Texas Utilities in respect of any New Texas Utilities Shares to which
           such holder becomes entitled pursuant to this acceptance of the Texas
           Utilities Offer and under the Share Alternative (subject to the
           provisions of Texas Utilities's restated articles of incorporation
           and bylaws) and to procure the despatch by post (or by such other
           method as may be approved by the Panel) of the document(s) of title
           for such New Texas Utilities Shares, at the risk of such holder, to
           the person whose name and address is set out in Box 2 (or as the case
           may be, Box 6 or Box 10) of the Form of Acceptance provided that this
           is outside Canada, Australia or Japan.

(e) that subject to the Texas Utilities Offer becoming or being declared wholly
    unconditional (or if the Texas Utilities Offer will become unconditional in
    all respects or lapses immediately upon the outcome of the resolution in
    question) or if the Panel otherwise gives its consent and pending
    registration:
 
    (i)  TU Acquisitions or its agents shall be entitled to direct the exercise
         of any votes attaching to any Energy Group Securities in respect of
         which the Texas Utilities Offer has been accepted or is deemed to have
         been accepted and not validly withdrawn and any of the rights and
         privileges attaching to such Energy Group Securities including the 
         right to requisition a general meeting of The Energy Group or of 
         holders of any class of its securities; and
 
    (ii) the execution of the Form of Acceptance and its delivery to the United
         Kingdom Receiving Agent or US Depositary shall constitute:
 
         (aa) an authority to The Energy Group or its agents from such holder to
              send any notice, circular, warrant, document or other 
              communication which may be required to be sent to him or her as a 
              shareholder of The Energy Group to TU Acquisitions at its 
              registered office;
 
         (bb) an authority to TU Acquisitions or its agents to sign any consent
              to short notice of a general meeting or separate class meeting on
              his behalf and/or to execute a form of proxy in respect of such
              Energy Group Shares appointing any person nominated by TU
              Acquisitions to attend general meetings and separate class 
              meetings of The Energy Group or its members (or any of them) (or 
              any adjournment of them) and to exercise the votes attaching to 
              such Energy Group Shares on his behalf, such votes to be cast so 
              far as possible to satisfy any outstanding Condition or otherwise
              as TU Acquisitions or its agents sees fit; and
 
         (cc) the agreement of such holder not to exercise any of such rights
              without the consent of TU Acquisitions and the irrevocable
              undertaking of such holder not to appoint a proxy for or to attend
              general meetings or separate class meetings;
 
(f)  that such holder will deliver, or procure the delivery to the United
     Kingdom Receiving Agent or US Depositary of, his share certificates and/or
     other documents of title in respect of the Energy Group Shares referred to
     in paragraph 12(a) above in certificated form, or an indemnity acceptable
     to TU Acquisitions in lieu thereof, as soon as possible and in any event

DELIVERY OF THE FORM OF ACCEPTANCE AND CERTIFICATES REPRESENTING ENERGY GROUP
SHARES AND/OR OTHER DOCUMENTS OF TITLE TO THE US DEPOSITARY WILL CONSTITUTE
DELIVERY OF THEM TO THE UNITED KINGDOM RECEIVING AGENT FOR THE PURPOSES OF
PARAGRAPH 11 OF THIS PART B OF APPENDIX I ABOVE AND THIS PARAGRAPH.
 
13  CERTAIN PROVISIONS CONCERNING ACCEPTANCES
 
(a) Without prejudice to the right reserved by TU Acquisitions to treat
    Acceptance Forms as valid even though not entirely in order or not
    accompanied by, where Energy Group Shares are in certificated form, the
    relevant share certificates and/or other documents of title, or not
    accompanied by the relevant transfer to escrow, except as otherwise agreed
    by the Panel:
 
     (i) an acceptance of the Texas Utilities Offer will only be counted towards
         fulfilling the Acceptance Condition if the requirements of Note 4 and,
         if applicable, Note 6 to Rule 10 of the City Code are satisfied in
         respect of such acceptance. For additional information on Note 4 and
         Note 6 to Rule 10 of the City Code, see paragraph 13(b) below;
                                      I-27
<PAGE>   62
 
     (ii) a purchase of Energy Group Securities by TU Acquisitions or its
          nominee(s) (or a person acting in concert with TU Acquisitions or its
          nominee(s)), will only be counted towards fulfilling the Acceptance
          Condition if the requirements of Note 5 and, if applicable, Note 6 to
          Rule 10 of the City Code are satisfied in respect of such purchase.
          For additional information on Note 5 and Note 6 to Rule 10 of the City
          Code, see paragraph 13(b) below; and
 
     (iii)the Acceptance Condition will not be declared satisfied until the
          United Kingdom Receiving Agent has issued a certificate to TU
          Acquisitions (or its agent) which states the number of Energy Group
          Securities in respect of which acceptances have been received which
          comply with paragraph 13(a)(i) above and the number of Energy Group
          Securities otherwise acquired, whether before or during the Initial
          Offer Period, which comply with paragraph 13(a)(ii) above.
 
(b)  Notes 4 to 6 to Rule 10 of the City Code contain detailed provisions for
     verifying which acceptances and purchases may be counted towards fulfilling
     the Acceptance Condition or in determining whether the Acceptance Condition
     has been fulfilled and are principally concerned to ensure that the
     acceptor is the registered owner of the securities which he is tendering.
     The principal requirements of Notes 4 to 6 to Rule 10 are that any
     Acceptance Form must be completed to a suitable standard (i.e., it must
     constitute a transfer or a valid and irrevocable appointment of TU
     Acquisitions of some person on its behalf or as agent or attorney for the
     purpose of executing a transfer) and it must be accompanied by, where
     Energy Group Shares are in certificated form, the appropriate share
     certificate(s) or other document(s) of title and, in all cases, any
     relevant supporting documentation (such as powers of attorney). Immediately
     prior to the satisfaction of the Acceptance Condition the United Kingdom
     Receiving Agent will issue a certificate to TU Acquisitions stating the
     number of Energy Group Securities tendered and not validly withdrawn
     pursuant to the Texas Utilities Offer and the number of Energy Group
     Securities otherwise acquired, on or before the Initial Closing Date as the
     case may be, in compliance with the provision referred to in paragraph
     13(a) above. Copies of such certificates will be sent to the Panel as soon
     as possible after they are issued.
 
(c)  Subject to the City Code, TU Acquisitions reserves the right to treat as
     valid in whole or in part any acceptance of the Texas Utilities Offer which
     is not entirely in order or which is not accompanied by the (as applicable)
     relevant transfer to escrow or the relevant share certificate(s) and/or
     other document(s) of title or which is received by it at a place or places
     other than set out in this document or the Acceptance Form. In that event,
     the consideration under the Texas Utilities Offer will be despatched only
     after the relevant transfer to escrow has settled or (as applicable) the
     relevant share certificate(s) and/or document(s) of title or indemnities
     satisfactory to TU Acquisitions have been received.
 
14  SUBSTITUTE ACCEPTANCE FORMS
 
The holders of Energy Group Securities have been sent with this document either
a Letter of Transmittal (accompanied by a Notice of Guaranteed Delivery) and/or
a Form of Acceptance. All holders of Energy Group ADSs have been sent a Letter
of Transmittal and a Notice of Guaranteed Delivery, which they must use to
tender their Energy Group ADSs and accept the Texas Utilities Offer. All holders
of Energy Group Shares, including persons in the US who hold Energy Group
Shares, have been sent a Form of Acceptance, which they must use to tender their
Energy Group Shares and accept the Texas Utilities Offer. Should any holder of
Energy Group Securities receive an incorrect form with which to accept the Texas
Utilities Offer or require any additional forms, that person should contact the
United Kingdom Receiving Agent or the US Depositary at the addresses set out at
the end of this document, who will provide the appropriate forms.
 
15  SETTLEMENT
 
Subject to the satisfaction, fulfilment or, where permitted, the waiver of all
Conditions (except as provided in paragraph 9 of this Part B of Appendix I in
the case of certain overseas holders of Energy Group Securities), settlement of
the consideration to which any holder of Energy Group Securities is entitled
under the Texas Utilities Offer will be effected (i) in the case of acceptances
received, complete in all respects, by the Initial Closing Date, within 14 days
of such date, or (ii) in the case of acceptances of the Texas Utilities Offer
 
                                      I-28
<PAGE>   63
 
received, complete in all respects, after such date, but while the Texas
Utilities Offer remains open for acceptance, within 14 days of such receipt, in
the following manner:
 
(a)  ENERGY GROUP SHARES IN UNCERTIFICATED FORM (THAT IS, IN CREST)
     Where an acceptance relates to Energy Group Shares in uncertificated form,
     the cash consideration to which the accepting holder of Energy Group Shares
     is entitled will be paid by means of CREST by TU Acquisitions procuring the
     creation of an assured payment obligation in favour of such accepting
     holder's payment bank in respect of the cash consideration due, in
     accordance with the CREST assured payment arrangements (other than any US
     dollar amount which will be payable by cheque). Loan Notes or receipts or
     definitive certificates for New Texas Utilities Shares will be despatched
     by first class post (or by such other method as may be approved by the
     Panel). TU Acquisitions reserves the right to settle all or any part of the
     consideration referred to in this paragraph, for all or any accepting
     holders of Energy Group Securities, in the manner referred to in paragraph
     15(b) below, if, for any reason, it wishes to do so.
 
(b)  ENERGY GROUP SECURITIES IN CERTIFICATED FORM
     Where an acceptance relates to Energy Group Securities in certificated
     form, cheques for cash due or Loan Notes or receipts or definitive
     certificates for New Texas Utilities Shares will be despatched by first
     class post (or by such other method as may be approved by the Panel).
 
16  CURRENCY OF CASH CONSIDERATION
 
Instead of receiving cash consideration in pounds sterling, holders of Energy
Group Shares who so wish may receive US dollars on the following basis: the cash
amount payable in pounds sterling to which such holder would otherwise be
entitled pursuant to the terms of the Texas Utilities Offer will be converted,
without charge, from pounds sterling to US dollars at the exchange rate
obtainable by the relevant payment agent (either the United Kingdom Receiving
Agent or the US Depositary) on the spot market in London at approximately noon
(London time) on the date the cash consideration is made available by TU
Acquisitions to the relevant payment agent for delivery in respect of the
relevant Energy Group Shares. A holder of Energy Group Shares may receive such
amount on the basis set out above only in respect of the whole of his holding of
Energy Group Shares in respect of which he accepts the Texas Utilities Offer.
Holders of Energy Group Securities may not elect to receive both pounds sterling
and US dollars. Unless they elect to receive pounds sterling, holders of Energy
Group ADSs will receive consideration converted into US dollars as described
above, as if such holders of Energy Group ADSs had elected to receive dollars.
Consideration in US dollars may be inappropriate for holders of Energy Group
Shares other than persons in the US and holders of Energy Group ADSs.
 
THE ACTUAL AMOUNT OF US DOLLARS RECEIVED WILL DEPEND UPON THE EXCHANGE RATE
PREVAILING ON THE BUSINESS DAY ON WHICH FUNDS ARE MADE AVAILABLE TO THE RELEVANT
PAYMENT AGENT BY TU ACQUISITIONS. HOLDERS OF ENERGY GROUP SECURITIES SHOULD BE
AWARE THAT THE US DOLLAR/POUNDS STERLING EXCHANGE RATE WHICH IS PREVAILING AT
THE DATE ON WHICH AN ELECTION IS MADE TO RECEIVE DOLLARS AND ON THE DATES OF
DESPATCH AND RECEIPT OF PAYMENT MAY BE DIFFERENT FROM THAT PREVAILING ON THE
BUSINESS DAY ON WHICH FUNDS ARE MADE AVAILABLE TO THE RELEVANT PAYMENT AGENT BY
TU ACQUISITIONS. IN ALL CASES, FLUCTUATIONS IN THE US DOLLAR/POUNDS STERLING
EXCHANGE RATE ARE AT THE RISK OF ACCEPTING HOLDERS OF ENERGY GROUP SECURITIES
WHO ELECT OR ARE TREATED AS HAVING ELECTED TO RECEIVE THEIR CONSIDERATION IN US
DOLLARS. NEITHER TU ACQUISITIONS NOR ANY OF ITS ADVISERS OR AGENTS SHALL HAVE
RESPONSIBILITY WITH RESPECT TO THE ACTUAL AMOUNT OF CASH CONSIDERATION PAYABLE
OTHER THAN IN POUNDS STERLING.

                                  APPENDIX II
 
 DESCRIPTION OF TEXAS UTILITIES CAPITAL STOCK; COMPARISON OF SHAREHOLDER RIGHTS
 
1  DESCRIPTION OF TEXAS UTILITIES CAPITAL STOCK
 
     The authorized capital stock of Texas Utilities consists of Common Stock,
without par value, of which 245,237,559 shares were outstanding at 31 December
1997 and serial preference stock, par value $25 per share, of which none is
outstanding. The following statements with respect to such capital stock of
Texas Utilities are a summary of certain rights and privileges attaching to the
stock under the laws of the State of Texas and the Restated Articles of
Incorporation of Texas Utilities ("Texas Utilities Articles") and Bylaws, as
amended, of ("Texas Utilities Bylaws"). This summary does not purport to be
complete and is qualified in its entirety by reference to such laws, the Texas
Utilities Articles and Texas Utilities Bylaws for complete statements.
 
     Each holder of Texas Utilities Common Stock is entitled to one vote for
each share of Texas Utilities Common Stock held on all questions submitted to
shareholders and to cumulative voting at all elections of directors. The Texas
Utilities Common Stock has no preemptive or conversion rights. Upon issuance and
delivery, the New Texas Utilities Shares, will be fully paid and nonassessable.
 
     The holders of the preference stock are not accorded voting rights, except
that, when dividends thereon are in default in an amount equivalent to four full
quarterly dividends, the holders of the preference stock are entitled to vote
for the election of one-third of the Board of Directors or two Directors,
whichever is greater, and, when dividends are in default in an amount equivalent
to eight full quarterly dividends, for the election of the smallest number of
Directors necessary so that a majority of the full Texas Utilities Board shall
have been elected by the holders of the preference stock. Texas Utilities must
also secure the approval of the holders of two-thirds of the outstanding shares
of preference stock prior to effecting various changes in its capital structure.
 
     After the payment of full preferential dividends on the preference stock,
holders of Texas Utilities Common Stock are entitled to dividends when and as
declared by the Texas Utilities Board of Directors. After payment to the holders
of preference stock of the preferential amounts to which they are entitled, the
remaining assets to be distributed, if any, upon any dissolution or liquidation
of Texas Utilities shall be distributed to the holders of the Texas Utilities
Common Stock. Each share of Texas Utilities Common Stock is equal to every other
share of Texas Utilities Common Stock with respect to dividends and also with
respect to distributions upon any dissolution or liquidation.
 
     The Texas Utilities Common Stock is listed on the NYSE, CSE and PSE.
 
     The transfer agent and registrar for the Texas Common Stock is Texas
Utilities Shareholder Services, Dallas, Texas.
 
2  COMPARISON OF SHAREHOLDER RIGHTS
 
     There are a number of differences between the rights attaching to shares of
Texas Utilities Common Stock, as detailed above, and those attaching to Energy
Group Shares. Certain rights attaching to Energy Group Shares, where those
differences exist, are identified below. Such differences may arise from the
differences between legislation and regulations governing The Energy Group and
those governing Texas Utilities as well as between the constitutional documents
of the two companies. The following is not a complete description of the
differences between the rights associated with Energy Group Shares as compared
to New Texas Utilities Shares. Further, it does not address the differing rights
of holders of Texas Utilities preference stock.
 
     For a complete understanding of such differences, holders of Energy Group
Securities are referred to the laws and applicable regulations of England, the
United States and the State of Texas, the rules of the London Stock Exchange,
the NYSE, the CSE, the PSE and the constitutional documents of both The Energy
Group and Texas Utilities.
 
                                      II-1
<PAGE>   65
 
General
 
     The Energy Group is incorporated in England and operates in accordance with
the Companies Act. Rules and regulations governing trading of Energy Group
Shares differ from those relating to shares of Texas Utilities Common Stock.
 
Dividends
 
     Pursuant to The Energy Group's articles of association, and subject to the
restrictions of English law, dividends may be declared by the Board of The
Energy Group, or by The Energy Group, on the recommendation of the Board, by
ordinary resolution in an amount not to exceed that recommended by the Board.
 
Meetings
 
     The holders of not less than one tenth of the paid up voting capital of The
Energy Group have the right to requisition general meetings of shareholders.
 
Transfers
 
     The Energy Group articles of association allow The Energy Group Board, in
its absolute discretion, and without giving any reason for so doing, to refuse
to register certain transfers of shares, being shares which are not fully paid
up, or being shares, whether fully paid up or not, which are in favour of more
than four joint transferees.

                                  APPENDIX III
 
                     SUMMARY OF THE TERMS OF THE LOAN NOTES
 
The unsecured floating rate loan notes 1998/2004 of TU Acquisitions will be
created by a resolution of the Board of TU Acquisitions (or a duly authorised
committee of TU Acquisitions) and will be constituted by a loan note instrument
(the "Loan Note Instrument") executed as a deed by TU Acquisitions. The Loan
Notes will not be guaranteed. The issue of the Loan Notes will be conditional on
the Texas Utilities Offer becoming or being declared unconditional in all
respects. Loan Notes will only be issued if the aggregate valid elections for
the Loan Note Alternative received on or before the date on which the Texas
Utilities Offer becomes or is declared unconditional in all respects will result
in TU Acquisitions issuing in excess of L1 million nominal value of Loan Notes.
The Loan Note Alternative is not (subject to certain exceptions) available to
persons with registered addresses in the United States, Canada, Japan or
Australia or to or for the account or benefit of any US Person. The Loan Note
Instrument will contain provisions, among others, to the effect set out below.
 
1 FORM AND STATUS
 
The Loan Notes will be issued by TU Acquisitions in registered form in amounts
and integral multiples of L1 and will constitute unsecured obligations of TU
Acquisitions ranking pari passu with its other unsecured obligations apart from
those preferred by law. Fractional entitlements will be disregarded. The Loan
Note Instrument will not contain any restrictions on borrowing, disposals or
charging of assets by TU Acquisitions or any member of the Texas Utilities
Group.
 
2 INTEREST
 
a) Interest on the Loan Notes will accrue from day to day and will be calculated
   on the basis of a 365-day year (or in the case of a leap year, a 366-day
   year) and will be payable (subject to any requirement to deduct income tax
   therefrom) twice yearly in arrears on 30 June and 31 December or, if any such
   day is not a business day, on the immediately preceding business day
   ("interest payment dates") in each year in respect of the interest periods
   (as defined below) ending on those dates at a rate calculated as provided in
   sub-paragraph 2(b) below or, if no rate can be established in accordance with
   sub-paragraph 2(b) below, as provided in sub-paragraph 2(c) below, except
   that the first payment of interest on any Loan Note, which will be made on 31
   December 1998, will be in respect of the period from the date of issue of
   such Loan Note to 31 December 1998 (both dates inclusive). The period from
   the date of issue of such Loan Notes to 31 December 1998 and the period from
   the day following 31 December 1998, or any subsequent interest payment date,
   to the next following interest payment date (inclusive of the next following
   interest payment date) is herein called an "interest period".
 
b) The rate of interest on the Loan Notes for each interest period will be that
   calculated by TU Acquisitions to be 0.5 per cent. below the rate per annum of
   the offer quotation for six months' deposits in sterling for an interest
   period which appears on Telerate Page 3750 at or about 12.00 noon (showing
   the rate as at or about 11.00 am) on the first day of the relevant interest
   period, except that in the case of the first interest period (being from the
   date of the issue of each Loan Note to 31 December 1998) such calculation
   will be made on the day on which any of the Loan Notes are first issued or,
   if any such day is not a business day, on the next succeeding business day
   (the "Calculation Day"). If no such offer quotation as at or about 11.00 am
   appears on Telerate Page 3750 on or before 3.00 pm on the Calculation Day,
   the rate of interest for each interest period shall be the arithmetic mean
   (rounded upward to the nearest five decimal places) of the offer quotations
   for sterling deposits for a period equal, or as nearly equal as possible, to
   an interest period which appear on the Reuters Screen LIBP Page at or about
   11.00 am on the Calculation Day. Any calculation of the rate of interest and
   of each such interest amount shall, in the absence of manifest error, be
   final and binding.
 
c) If a rate of interest cannot be established in accordance with the provisions
   in sub-paragraph 2(b) above for any interest period, then the rate of
   interest on the Loan Notes for such interest period shall be calculated by
   reference to a rate 0.5 per cent. below such rate as TU Acquisitions shall
   determine on the
 
                                      III-1
<PAGE>   67
 
   basis of quotations made by reference to a London clearing bank or a group of
   London clearing banks as selected by TU Acquisitions or (failing which) to
   rates offered in any other sterling inter-bank market or markets as TU
   Acquisitions may select, and if a rate of interest cannot be established in
   accordance with the above provisions of this sub-paragraph for any interest
   period then the applicable rate of interest shall be the same as that
   applicable to the Loan Notes during the previous interest period.
 
3 REDEMPTION OF LOAN NOTES
 
a) A holder of Loan Notes ("Noteholder") shall be entitled to require TU
   Acquisitions to redeem the whole (whatever the amount) or any part of his
   holding of Loan Notes at par, together with accrued interest (subject to any
   requirement to deduct income tax therefrom) to (and including) the date of
   payment, on 31 December 1998, and on any interest payment date falling
   thereafter by giving notice in writing to TU Acquisitions (in the form
   endorsed on the Loan Note certificate) not less than 30 days prior to such
   interest payment date accompanied by the certificate(s) for all the Loan
   Notes to be redeemed, provided that no such notice may be given in respect of
   any Loan Notes for which notice of redemption has previously been given by TU
   Acquisitions in accordance with sub-paragraph 3(b) below.
 
b) If, at any time, the nominal amount of all Loan Notes outstanding is 20 per
   cent. or less of the total nominal amount of Loan Notes issued, TU
   Acquisitions shall have the right on giving to the remaining Noteholders not
   less than 30 days' notice in writing, such notice not to take effect prior to
   31 December 1998, to redeem, on the expiry of such notice, all (but not some
   only) of the outstanding Loan Notes by payment of the nominal amount thereof
   together with accrued interest (subject to any requirement to deduct income
   tax therefrom) to (and including) the date of redemption.
 
c) Any Loan Notes not previously so redeemed or purchased will be repaid in full
   at par on 31 December 2004.
 
4 PURCHASE OF LOAN NOTES
 
TU Acquisitions will be entitled at any time after 31 December 1998 to purchase
Loan Notes at any price by tender, private treaty or otherwise by agreement with
the relevant Noteholder(s).
 
5 CANCELLATION
 
Any Loan Notes redeemed under paragraph 3 above or purchased under paragraph 4
above shall be cancelled and shall not be available for re-issue.
 
6 MODIFICATIONS
 
The provisions of the Loan Note Instrument and the rights of the Noteholders
will be subject to modification, abrogation or compromise in any respect with
the sanction of an Extraordinary Resolution of the Noteholders, as defined in
the Loan Note Instrument, subject to the consent of TU Acquisitions. TU
Acquisitions may amend the provisions of the Loan Note Instrument without such
sanction or consent if, in the reasonable opinion of the financial adviser to TU
Acquisitions, such amendment would not be materially prejudicial to the
interests of Noteholders or is of a formal, minor or technical nature or
corrects a manifest error.
 
7 REGISTRATION AND TRANSFER
 
The Loan Notes will be registered in amounts and multiples of L1. The Loan Notes
will be transferable in amounts or integral multiples of L1.
 
                                      III-2
<PAGE>   68
 
8 RESTRICTIONS ON OWNERSHIP AND TRANSFER
 
Notwithstanding the foregoing, prior to the date occurring 180 days after the
last date of issue of any Loan Notes pursuant to the Texas Utilities Offer or,
where applicable, pursuant to the provisions of sections 428 to 430F of the
Companies Act:
 
a) no transfer of Loan Notes will be registered until each transferee has
   delivered to TU Acquisitions a certificate in the prescribed form to the
   effect that such transferee is not a US Person and is not acquiring, and will
   not be holding, such Loan Notes for the account or benefit of a US Person or
   with a view to the offer, sale or delivery, directly or indirectly, of such
   Loan Notes in the United States, Canada, Australia or Japan, or to or for the
   account or benefit of any US Person or any other person whom such transferee
   has reason to believe is purchasing for the purpose of such offer, sale or
   delivery;
 
b) payments of interest or principal in respect of the Loan Notes will not be
   made to addresses in the United States, Canada, Australia or Japan;
 
c) documents of title in respect of the Loan Notes will not be sent to addresses
   in the United States, Canada, Australia or Japan; and
 
d) registered addresses of holders of Loan Notes must be outside the United
   States, Canada, Australia or Japan.
 
9 PRESCRIPTION
 
Noteholders will cease to be entitled to amounts in respect of interest which
remain unclaimed for a period of 12 years, and to amounts due in respect of
principal which remain unclaimed for a period of 12 years, in each case from the
date on which the relevant payment first becomes due, and such amounts shall
revert to TU Acquisitions.
 
10 FURTHER LOAN NOTES
 
Provision will be made in the Loan Note Instrument to enable TU Acquisitions to
make further issues of the Loan Notes so as to form a single series with the
Loan Notes issued pursuant to the Texas Utilities Offer or to carry such rights
as to interest, redemption and otherwise as TU Acquisitions may think fit.
 
Each Noteholder will have the right to acquire by subscription at par additional
loan notes, to be issued by a subsidiary of TU Acquisitions (the "Additional
Notes"), having a nominal value of an amount up to or equal to such Noteholder's
holding of Notes, on terms and conditions substantially the same as those
applicable to the Loan Notes, except as follows:
 
a) the rate of interest will be 1.5 per cent. below the rate per annum described
   in paragraph 2(b) above; and
 
b) the Additional Notes will not carry any right to acquire any additional
   securities.
 
The right to subscribe for Additional Notes will be exercisable on and after 31
December 2003.
 
11 NO LISTING
 
No application has been made or is intended to be made for the Loan Notes to be
listed or dealt in on any stock exchange.
 
12 EVENTS OF DEFAULT
 
Each Noteholder shall be entitled to require all or any part of the Loan Notes
held by him to be repaid at par together with accrued interest (subject to any
requirement to deduct any income tax therefrom) whilst any of the following is
continuing:
 
a) any principal or interest on any of the Loan Notes held by that Noteholder
   shall fail to be paid in full within 30 days after the due date for payment
   thereof; or
 
                                      III-3
<PAGE>   69
 
b) an order is made or an effective resolution is passed for the winding-up or
   dissolution (or any equivalent procedure in any other jurisdiction) of TU
   Acquisitions (other than for the purposes of an amalgamation or
   reconstruction or a members' voluntary winding-up upon terms previously
   approved by Extraordinary Resolution); or
 
c) an encumbrancer takes possession or a trustee, receiver or an administrator,
   administrative receiver or similar officer is appointed of all or
   substantially all of the undertaking of TU Acquisitions and such person has
   not been paid out or discharged within 30 days.
 
13 SUBSTITUTION
 
The Loan Notes will contain provisions entitling TU Acquisitions, without the
consent of Noteholders, to substitute any of its subsidiaries or any holding
company or subsidiaries of such holding company resident in the United Kingdom
for tax purposes (other than Eastern or any of its subsidiaries) as the
principal debtor under the Loan Notes, or to require all or any of the
Noteholders to exchange their Loan Notes for loan notes issued on the same terms
mutatis mutandis by any such company provided that (a) TU Acquisitions
guarantees such company's obligations thereunder; and (b) following such
substitution or exchange, the Loan Notes or (as the case may be) such loan notes
shall not contain a provision equivalent to this paragraph 13. References to TU
Acquisitions in this summary shall be construed accordingly. TU Acquisitions'
right to require substitution of such company as principal debtor (but not the
right to require exchange of the Loan Notes) will be exercisable only if prior
clearance has been obtained from the Inland Revenue to the effect that the
substitution will not be treated as a disposal of the Loan Notes for the
purposes of United Kingdom taxation of chargeable gains and TU Acquisitions'
right to require such an exchange will be exercisable only if the exchange will
fall within section 135 of the Taxation of Chargeable Gains Act 1992 and, to the
extent relevant, clearance has been received from the Inland Revenue under
section 138 of that Act in respect of the exchange.
 
14 GOVERNING LAW
 
The Loan Notes and the Loan Note Instrument will be governed by and construed in
accordance with English Law.

              FINANCIAL AND OTHER INFORMATION ON THE ENERGY GROUP
 
1   RESULTS FOR THE NINE MONTHS ENDED 31 DECEMBER 1997.
 
The text on pages IV-1 to IV-3 is a reproduction of the announcement made by The
Energy Group on 3 February 1998:
 
                   "THE ENERGY GROUP -- THIRD QUARTER RESULTS
 
                              FINANCIAL HIGHLIGHTS
 
- - TURNOVER AT L3.4 BILLION UP 10%
 
- - OPERATING PROFIT UP 15%
 
The Energy Group PLC today announces its results for the period 1 October 1997
to 31 December 1997. The results for the quarter have been compared to the pro
forma operating results for the equivalent period in 1996 of certain of the
businesses which were previously reported as part of Hanson plc.
 
FINANCIAL RESULTS
 
Group turnover for the nine months to 31 December 1997 was L3,390 million, an
increase of 10 per cent. on the same period last year (pro forma 1996: L3,084
million). Operating profit for the nine month period was L379 million up 15 per
cent. (pro forma 1996: L330 million), before exceptional costs associated with
the Pacificorp bid and restructuring charges. Pre-exceptional earnings per share
for this period were 40.0p.
 
TRADING
 
COAL
 
Third quarter turnover declined slightly to L323 million (pro forma 1996: L325
million) mainly due to adverse exchange rate movements. Operating profit rose 8
per cent. to L27 million (pro forma 1996: L25 million). Peabody sold 40 million
tons (1996: 41 million tons) of steam and metallurgical coal during the quarter
and its steam coal products continue to fuel approximately 9 per cent. of all
electricity produced by US electricity companies.
 
POWER
 
Third quarter turnover was up 17 per cent. to L1,005 million (pro forma: L860
million) and operating profit rose 88 per cent. to L107 million (pro forma 1996:
L57 million). This substantial improvement reflects an excellent performance
from our trading activities including Citizens Power and the UK coal-fired power
stations. The new gas-fired power station at King's Lynn was fully commissioned
in December and Eastern's gas and electricity retail business has also shown an
upturn, reflecting improved margins.
 
NETWORKS
 
Third quarter turnover rose 9 per cent. to L139 million (pro forma: L127
million) with operating profit increasing 18 per cent. to L66 million (pro forma
1996: L56 million). These improved results are mainly due to property disposal
and other one-off profits. The underlying networks business was broadly flat,
reflecting continuing regulatory price reductions, offset by cost reductions.
 
Derek Bonham, Chairman, said: "These results demonstrate the strengths of The
Energy Group's businesses. The increases in profit in our three sectors are very
encouraging. With our mix of generating capacity this was always going to be a
good quarter for us.
 
Today we have announced the terms of a recommended renewed offer by Pacificorp
for The Energy Group. Together we can create a group with the scale and scope of
operations to compete more effectively in international energy markets. Detailed
terms of the offer will be mailed to our shareholders shortly."

Notes:
 
(1) Turnover and operating profit for coal include the results for contract
    restructuring.
 
(2) Pro forma adjustments have been made to the figures to 31 December 1996 in
    respect of the additional administration costs that arose following the
    demerger. The directors estimate that such costs amount to approximately L15
    million per annum.
 
(3) Exceptional costs in the nine months ended 31 December 1997 relate to L7
    million of restructuring costs within the Power segment and bid-related
    costs of L10 million, of which L1 million arose in the quarter ended 31
    December 1997.
 
(4) The earnings per share for the 9 months ended 31 December 1997 are based on
    the profits for that period and on 516,756,926 shares which excludes the
    4,100,891 shares held by The Energy Group Employee Benefit Trust, which has
    waived the right to dividends on the shares it holds.

ITEM 1. DESCRIPTION OF BUSINESS
 
        Energy, a public limited company incorporated in England and Wales, owns
and operates a diversified international energy group which includes Peabody,
the world's largest private producer of coal, and Eastern, one of the largest
integrated electricity and gas groups in the UK. The registered office of Energy
is located at 117 Piccadilly, London W1V 9FJ, and its telephone number is (44)
171 647 3200.
 
        Energy's strategy is to establish itself as a leading integrated
international energy business in the United States, the United Kingdom,
Australia and elsewhere through building a presence across the value chain in
these markets and by exploiting the potential created by the continuing
privatization of electricity generation, networks and sales in world markets.
 
COAL
 
        Through Peabody, the largest producer of coal in the US, Energy
operated, as of March 31, 1997, 26 underground and surface mines in the US and
three surface mines in Australia:
 
        -     As of March 31, 1997, Peabody owned a controlled 9.5 billion tons
              of proven and probable coal reserves which is the largest coal
              reserve base of any active private mining company in the US;
 
        -     In the six months ended March 31, 1997, Peabody sold 81.4 million
              tons of coal representing an estimated 14.4% of the US market; and
 
        -     Peabody Australia, one of the ten largest coal producers in
              Australia, has interests in four surface mines in New South Wales,
              three of which are currently in operation. Peabody's equity share
              of
<PAGE>   77
 
         the coal sales of these mines amounted to 3.5 million tons in the six
         months ended March 31, 1997 and its equity share of the proven and
         probable reserves associated with these mines as of March 31, 1997
         amounted to 466 million tons.
 
POWER AND NETWORKS
 
        Through Eastern, Energy is one of the leading integrated electricity and
gas groups in the UK:
 
        -     Eastern Generation, the fourth largest generator of electricity in
              Great Britain, currently owns, operates or has an interest in
              eight power stations, representing approximately 10% of the total
              registered generating capacity of 71,850 MW as of March 31, 1997;
 
        -     Eastern Power & Energy Trading manages for the Group the price and
              volume risks associated with electricity generation and the supply
              of fuels required for electricity generation, and with the
              wholesaling and retailing of electricity and natural gas. These
              exposures are managed by trading its contract portfolio and by
              bidding Eastern's generation output into the Pool. Eastern Power &
              Energy Trading also has small equity interests in three natural
              gas producing fields in the North Sea;
 
        -     Eastern Natural Gas is one of the largest suppliers of natural gas
              in the UK after Centrica plc (formerly part of British Gas); and
 
        -     Eastern Electricity is the largest supplier and distributor of
              electricity in England and Wales, with over three million
              customers and an authorized area covering approximately 20,300
              square kilometers in the east of England and parts of north
              London.
 
        Energy also owns Citizens Power LLC (formerly Citizens Lehman Power
L.L.C.) ("Citizens"), one of the leading US power marketing firms which was
acquired by the Group in May 1997. Its headquarters are in Boston and it has
field offices in Milwaukee, Denver and Toronto.
 
        Energy has been an independent, publicly owned company since February
24, 1997 when, through Energy, Hanson effected the demerger (i.e., spin-off) of
its energy businesses (the "Demerger"). Pursuant to the Demerger, on February
24, 1997, Hanson transferred Rollalong, a wholly-owned direct subsidiary of
Hanson which owned Eastern, Consolidated Gold Fields (which indirectly owned Lee
Ranch) and the companies which owned Peabody Australia, to Energy in
consideration for Energy issuing Ordinary Shares representing all of its then
outstanding share capital (other than subscriber shares) to holders of Hanson
Shares (including Hanson Shares represented by Hanson ADSs) on a pro rata basis
of one Ordinary Share for every ten Hanson Shares and one ADS for every eight
Hanson ADSs. On March 7, 1997, PUSH, a wholly-owned indirect subsidiary of
Hanson, transferred to Peabody Investments (which was and continues to be
approximately a 99.4% subsidiary of Energy, with subsidiaries of Hanson owning
the remaining 0.6% interest), the entire issued share capital of Peabody in
consideration for $1,637.5 million.
 
OFFER BY PACIFICORP ACQUISITIONS
 
        On June 13, 1997, Energy announced the terms of a recommended cash offer
(the "Offer") for Energy made on behalf of PacifiCorp Acquisitions, a
wholly-owned subsidiary of PacifiCorp. PacifiCorp is a diversified energy group
based in Portland, Oregon, serving retail electricity customers in Oregon,
Washington, California, Montana, Idaho, Utah and Wyoming. The terms of the
Offer, which was unanimously approved by Energy's Board of Directors, were 690p
per Ordinary Share and L27.60 per ADS, together with the right to retain the
dividend of 5.5p (net) per Ordinary Share paid on July 4, 1997 to those
shareholders on the register of members on June 27, 1997. The Offer valued the
equity of Energy at approximately L3,659 million (assuming the exercise in full
of all outstanding options and the vesting of all outstanding awards under
Energy's employee share schemes). Including the dividend referred to above, the
Offer represented a premium of approximately 31% to the closing price of 529.5p
per Ordinary Share on May 13, 1997, the business day one month before the
announcement of the Offer and a premium of approximately 24% to the closing
price of 561.5p per Ordinary Share on June 9, 1997, the last business day before
the announcement by Energy that it was involved in talks with PacifiCorp in
relation to the Offer.
 
        The Offer was subject to certain conditions and regulatory consents and
confirmations being obtained. On August 1, 1997, the UK Secretary of State for
Trade and Industry (the "Secretary of State") announced that she had concerns
over whether it would be possible to maintain adequate control over the merged
company and that, accordingly, she had decided to refer the proposed acquisition
of Energy by PacifiCorp to the Monopolies and Mergers Commission ("MMC"). The
MMC has a deadline of November 21, 1997 for completing its investigation
                                        2
<PAGE>   78
 
and reporting to the Secretary of State whether the proposed acquisition of
Energy by PacifiCorp operates or may be expected to operate against the public
interest. Following receipt of the MMC report the Secretary of State will
announce whether the acquisition has been cleared. The Secretary of State is not
required to make her decision within any specified time period. Even if the MMC
were to give the acquisition a conditional clearance, the Secretary of State has
the discretion to reject the MMC's recommendations.
 
        As a result of the referral to the MMC, the Offer immediately lapsed by
its own terms. Prior to the announcement of the referral, holders of Ordinary
Shares and ADSs representing approximately two-thirds of Energy's shares capital
had submitted valid acceptances of the Offer. PacifiCorp and Energy have each
stated that they will cooperate fully in the inquiry and respond promptly to
information requests by the MMC and are communicating with each other as
appropriate for this purpose. In addition, PacifiCorp and Energy are in the
process of complying with a request for additional information in relation to
the Offer by the US Federal Trade Commission (the "FTC") under the
Hart-Scott-Rodino Antitrust Improvements Act in relation to the potential
acquisition of Energy by PacifiCorp. It is uncertain when the FTC will complete
its review.
 
        In addition, there can be no assurance that the regulatory consents and
confirmations mentioned above will be obtained or, if obtained, that such
consents and confirmations will be on satisfactory terms, or that PacifiCorp
will make a new offer for Energy or, if made, that such offer will be on terms
acceptable to the Board of Directors of Energy, which would be required to
consider any new offer by PacifiCorp in the context of the circumstances then
prevailing.
 
DESCRIPTION OF THE BUSINESSES
 
COAL
 
        The Group's coal operations are conducted through Peabody. Peabody,
which is the largest producer of coal in the US and the largest private coal
producer in the world, currently operates 25 underground and surface mines in
the US (one small underground mine having been sold in June 1997) and three
surface mines in Australia and 11 processing plants. Since September 30, 1990,
the Group's total US and Australian annual sales have increased from 93 million
tons to 163 million tons in the year ended September 30, 1996 (81.4 million tons
in the six months ended March 31, 1997). The Directors estimate that the Group's
US market share has grown from 9% in the year ended September 30, 1990 to 15% in
the year ended September 30, 1996 with sales increasing from 156 million tons to
163 million tons. In the six months ended March 31, 1997, the Directors estimate
that the Group had a market share of 14% with sales of 74.8 million tons.
 
        Peabody's US operations are managed through four principal units: Powder
River; Peabody Western; Peabody East; and Lee Ranch. Peabody's 25 US mines sell
coal to 141 US power plants and Peabody also exports from the US to customers in
12 other countries, principally power generation plants and industrial users.
Peabody's head office in St. Louis, Missouri, provides general policy overview,
co-ordinates coal sales and business development activities and performs
financial management and consolidation functions, with a view to ensuring that
capital is allocated to the most profitable purposes.
 
        Peabody's base of approximately 9.5 billion tons of proven and probable
owned or controlled coal reserves has increased from approximately 7.0 billion
tons in 1990, and is the largest coal reserve base of any active private mining
company in the US. Certain of Peabody's coal reserves are held by Peabody
Development, a subsidiary of Peabody, which is responsible for acquiring coal
assets for future development and the disposal of coal and surface property
interests which have no further strategic value to the Group.
 
        Peabody has a substantial base of low sulfur coal reserves consisting of
approximately 4.7 billion tons and additional such reserves are available for
lease from private parties or federal, state or tribal governments, especially
in the Powder River Basin. Of the 51% of Peabody's coal reserves which are high
sulfur, many are located near coal-fired power stations which may make them
attractive for development because of the lower transportation costs. The US
Clean Air Act Amendments of 1990 (the "Clean Air Act Amendments"), which are
described under "Regulatory Matters" below, limit the ability of some of
Peabody's customers to burn higher sulfur coals unless they have installed, at
significant cost, "scrubbers", or are able to purchase so-called "emission
allowances". The development of the Group's high sulfur coal reserves is thus
dependent on the cost of such emission allowances, the cost and availability of
low sulfur coal and whether electric utilities install scrubbers to meet the
requirements of Phase II of the Clean Air Act Amendments by 2000 as described
under "Regulatory Matters" below.
 
        Peabody Australia is one of the ten largest coal producers in Australia.
It owns or holds joint venture interests in and also manages four surface mines
in New South Wales, Australia and is well positioned to serve the
 
                                        3
<PAGE>   79
 
growing market in the Asian Pacific Rim. One of these mines, Bengalla, is
currently under development and is scheduled to begin operations in 1999. In the
six months ended March 31, 1997, Peabody Australia's equity share of sales from
these mines totaled 3.5 million tons and its share of the proven and probable
reserves associated with these operations amounted to 466 million tons.

(1)      Recoverable reserves have been adjusted to take account of all losses
         involved in producing a saleable product.
(2)      The Roadside Mine, included in "Other", was sold in June 1997.
(3)      Assigned reserves are coal reserves which are legally recoverable,
         generally through existing facilities using current mining technology.
         Unassigned reserves are coal reserves which are also legally
         recoverable using current mining technology, but which require
         substantial capital investment for facilities to enable recovery of the
         coal.
 
        Reserve estimates are based on geological data assembled and analyzed by
Peabody's staff which includes 13 qualified geologists and more than 100
qualified engineers, based both at the individual mines and Peabody's
headquarters, and independent experts. The reserve estimates are reviewed by
them periodically to reflect new drilling or other data received and production
of coal from the reserves. Accordingly, reserve estimates will change from time
to time to reflect mining activities, analysis of new engineering and geological
data, changes in reserve holdings, modifications of mining methods and other
factors. Reserve information, including the quantity and quality (where
available) of reserves as well as production rates, surface ownership, lease
payments and other information relating to the Group's coal reserve and land
holdings, is maintained through the computerized land management system
developed by Peabody.
 
        Peabody's reserve base estimates are based on information obtained from
its extensive drilling program, which totals nearly 500,000 individual drill
holes. Data from individual drill holes are input into a computerized drill hole
system from which the depth, thickness and, where core drilling is used, the
quality of the coal, are determined. The density of the drill pattern determines
whether the reserves will be calculated as proven or probable. The drill hole
data are then input into the computerized land management system which overlays
the geological data with data on ownership or control of the mineral and surface
interests to determine the extent of the reserves in a given area. Drilling
operations are typically undertaken by qualified staff engineers and geologists.

        The cost and net book value of plant and equipment as extracted from the
Financial Statements included herein were L927 million and L395 million,
respectively, at March 31, 1997. In line with current accounting practice, the
Group's coal reserves and related plant and equipment have been individually
assessed to determine whether their value has been impaired in any way by market
or other circumstances. The carrying value of the reserves as stated in the
Financial Statements included herein reflects the results of that assessment.
 
        Of the Group's reserves, approximately 45% are owned by Peabody,
approximately 16% are leased from private parties and approximately 39% are
leased from federal, state or tribal governments.
 
        The private leases normally have terms of between 10 and 20 years, and
usually give Peabody the right to renew the lease for a stated period or to
maintain the lease in force until the exhaustion of mineable and merchantable
coal contained on the relevant site. These private leases provide for royalties
to be paid to the lessor either as a fixed amount per ton or as a percentage of
the sales price. Many leases also require payment of a lease bonus or minimum
royalty, payable either at the time of execution of the lease or in periodic
installments. Private leases are invariably maintained by active production.
Leases containing unassigned reserves may expire or such leases may be renewed
periodically. As mines deplete or reserves are assigned, production is often
commenced in a new mine to replace the depleted capacity.
 
        Peabody held, as at March 31, 1997, 24 federal coal leases which are
administered by the US Department of the Interior pursuant to the Federal Coal
Leasing Amendments Act of 1976. These leases cover Peabody's principal reserves
in Wyoming and other reserves in Montana and Colorado. Each of these leases
continues indefinitely provided that there is diligent development of the lease
and continued operation of the related mine or mines. The Bureau of Land
Management has asserted the right to adjust the terms and conditions of these
leases, including rents and royalties, after the first 20 years of their life
and at ten yearly intervals thereafter. Annual rents under Peabody's federal
coal leases are now set at $3.00 per acre. Production royalties on federal
leases are set by statute at 12.5% of the gross proceeds of coal mined and sold
for surface mined coal and 8% for underground mined coal. Similar provisions
govern Peabody's three coal leases with the Navajo and Hopi Indian tribes. These
leases cover coal contained in 65,000 acres of land in northern Arizona lying
within the boundaries of the Navajo and Hopi Indian reservations.
 
        Consistent with industry practice, Peabody conducts only limited
investigation of title to its coal properties prior to leasing. Title to lands
and reserves of the lessors or grantors and the boundaries of Peabody's leased
properties are not completely verified until such time as Peabody prepares to
mine such reserves.
 
        The following provides a description of the operating characteristics of
the principal mines and reserves of each of Peabody's US and Australian mining
units.
 
Powder River
 
        Powder River, which has its headquarters in Gillette, Wyoming, owns and
manages four large surface mines in Wyoming's coal-rich Powder River Basin. The
four mines are North Antelope, Rochelle, Caballo and Rawhide.
 
        Powder River's coal reserves are classified as surface mineable and
subbituminous. Coal is produced from the Wyodak-Anderson seam, which contains
low sulfur coal. The sulfur content of the coal in current production ranges
from 0.19% to 0.40% and the heat value ranges from 8,250 BTU to 8,850 BTU.
 
        The following table provides a summary of the main characteristics of
the principal mines of Powder River:

        North Antelope. The North Antelope mine, located adjacent to the
Rochelle mine, was opened in late 1983 and in calendar 1996 it was among the ten
largest US coal mines. The mine's approximately 250 employees use a 64-cubic
yard dragline along with truck and shovel methods to mine coal. Raw coal is
crushed and sized and stored in three 15,000 ton storage silos in preparation
for the automatic batch loading system, which can load coal into 100 ton rail
cars in 100 to 115 car unit trains at a rate of 6,000 tons per hour. Under state
regulations, North Antelope's current permitted annual capacity is 35 million
tons.
 
        Rochelle. The Rochelle mine is located 65 miles south of Gillette,
Wyoming. Its approximately 272 employees use modern truck and shovel methods.
The mine has two 15,000-ton silos and a 55,000-ton slot storage facility. Under
state regulations, it is permitted to mine up to 30 million tons of coal
annually. The Rochelle mine produces premium quality coal with a sulfur content
averaging 0.22% and a heat value range of 8,600 BTU to 8,800 BTU.
 
        Caballo. The Caballo mine, located 20 miles south of Gillette, Wyoming
employs approximately 233 persons. Caballo is a truck and shovel operation with

Peabody East
 
        Peabody East comprises principally Eastern Associated and Peabody Coal
Company.
 
        Eastern Associated, based in Charleston, West Virginia, owns or manages
five business units comprising six mines and related facilities in West
Virginia. These operations sell metallurgical and steam coal to customers in the
US and abroad. Approximately 38% of Eastern Associated's steam and metallurgical
coal is sold to export customers in Canada and approximately 10 other countries
worldwide and the remainder is sold to customers in the US. Approximately 54% of
Eastern Associated's production is sold to domestic electric utilities under
long-term contracts.
 
        Peabody Coal Company, whose headquarters are in Charleston, West
Virginia, operates five business units with eight mines in the midwestern US.
Peabody Coal Company's four underground and four surface mines, along with five
preparation plants and three barge loading facilities, are located in Kentucky,
Illinois and Indiana and currently employ approximately 2,052 people.
 
        Approximately 92% of Peabody Coal Company's coal is shipped to 18
electricity generating plants operated by domestic electric utilities in eight
states, principally in the midwest. Most of this coal is sold under long-term
contracts of five or more years in length. Approximately 8% of sales are to US
industrial customers who use the coal to produce their own electricity and steam
power. About 48% of Peabody Coal Company's coal is transported to customers by
river barge, approximately 49% by rail and most of the balance is carried on
conveyor belts to nearby power plants.

(2)      Sales relate to the Group's equity interest by mine. The totals
         represent Peabody Australia's equity interest.
 
(3)      Includes multiple seams.
 
        Ravensworth/Narama. Ravensworth mine is managed by Peabody Australia
under a long-term contract which runs to 2001 and requires the company to
produce approximately 4.5 million tons per year from coal reserves which are
under contract to Macquarie Generation, one of New South Wales' state electric
utilities. Ravensworth mines eight coal seams ranging from one to 26 feet thick.
The overburden is pre-stripped using trucks and power shovels followed by
draglines to uncover the lower three seams. The coal is trucked from the pit to
a crushing plant and then shipped raw by overland conveyor belt to Macquarie
Generation's nearby Bayswater and Liddell power stations.
 
        Narama mine opened in January 1993 and is operated as an extension of
the adjacent Ravensworth facility using similar mining techniques in the same
coal seams. Peabody Australia and RGC Limited, an Australian company, each hold
50% of Narama Joint Venture which has a 20-year contract running to 2012 to
supply about 2.3 million tons annually to Macquarie Generation. The mine's
employees come from a combined labor pool with Ravensworth which totals
approximately 364 people.
 
        Warkworth. Warkworth mine, seven miles southwest of Singleton, opened in
1981 and produces steam and met coal primarily for export. Peabody Australia
manages and owns 43.75% of the Warkworth Associates Joint Venture which owns the
mine. The mine is currently being expanded to produce approximately 4.9 million
tons of coal each year by 1999.
 
        Approximately 420 employees produce coal from five pits using truck and
shovel pre-stripping and dragline stripping techniques to uncover four to six
groups of seams. This coal is processed at Warkworth's preparation plant and
blended to customer specifications before being carried by overland conveyor to
the Mount Thorley rail loop and then by rail to the port of Newcastle. Warkworth
owns 13.9% of the Mount Thorley facility and 4.2% of a coal loading terminal at
the port.
 
        Bengalla. Peabody Australia also manages and holds a 35% interest in the
Bengalla joint venture which has been awarded a mining lease and a permit to
develop a new surface mine near Nuswellbrook, New South Wales, in the upper
Hunter Valley. The new mine is expected to produce up to six million tons of
steam coal per year for export beginning in 1999. The joint venture partners
include Taiwanese and Korean electric utilities and Japanese and Korean trading
companies.
 
Customers, Sales and Marketing
 
        Peabody COALSALES co-ordinates sales and marketing activities for all of
Peabody's US mining operations and also engages in brokerage transactions,
purchasing coal from or acting as agent to sell coal on behalf of other
producers. Its regional sales executives are responsible for marketing in their
assigned regions, while a central team co-ordinates sales activities and
provides marketing support from extensive industry databases.
 
                                       10
<PAGE>   86
 
        US Sales. Approximately 92% of Peabody's US coal sales volume for the
six months ended March 31, 1997 was sold to domestic electric utilities,
approximately 3% was sold to US industrial customers and approximately 5% was
exported to electric utility and steel making customers in 12 countries.
Approximately 90% of Peabody's US coal production was sold under supply
contracts with remaining terms from one to 17 years, and an average remaining
term of approximately six years. Typically, customers enter into supply
contracts to secure reliable sources of coal at predictable prices, while
Peabody seeks stable sources of revenue to support the investments required to
open, expand, maintain or improve productivity at mines needed to supply such
contracts. Such contracts are negotiated in the ordinary course of business.
Peabody currently has an order book of nearly 1,100 million tons of coal, of
which approximately 65% is scheduled for delivery after 2000.
 
        Most of Peabody's US coal supply contracts which have terms greater than
one year are subject to periodic price adjustments or "reopener" provisions
under which the contract price is subject to periodic adjustment by either party
to reflect the changes in the market price of coal. Furthermore, a majority of
the Group's coal supply contracts with terms greater than one year currently
have prices which exceed the price at which such coal could be sold in the spot
market. Over the last few years, a significant number of these contracts have
been renegotiated bringing the contract prices payable closer to current market
prices, thus leading to a reduction in the revenue received by Peabody albeit,
in many cases, offset to a large extent by one-time payments by the purchaser. A
similar reduction in contract prices has also been experienced in relation to
the replacement of expiring contracts. However, to date, the effect of such
reductions has been mitigated by lower operating costs and expansions and
acquisitions to increase sales volumes. The Directors believe that over the next
five years there is likely to be a continuing adverse impact on revenues under
such contracts because of renegotiation and replacement of existing contracts.
There can be no assurance that any reductions in revenues resulting therefrom
will continue to be mitigated by improvements in productivity or increased sales
volumes.
 
        From time to time, Peabody is involved in disputes with customers under
its long-term coal supply contracts relating to among other things, coal
quality, which have occasionally resulted in arbitration and other legal
proceedings. While customer disputes, if unresolved, could result in termination
or cancellation of the contract involved, Peabody's experience has been that
curative and/or dispute resolution measures decrease the likelihood of
termination or cancellation. In addition, Peabody's development of long-term
business relationships with many of its customers has generally permitted it to
resolve business disputes in a mutually acceptable manner.
 
        Australian Sales. Approximately 66% of the 5.0 million aggregate tons of
coal sold by the Australian mines in which Peabody Australia had an interest in
the six months ended March 31, 1997 (of which Peabody's equity share was 3.5
million tons) was sold under long-term contracts to the New South Wales power
utility, Macquarie Generation. The remainder was exported to Asian Pacific Rim
countries. Coal from the Ravensworth and Narama mines is sold to Macquarie
Generation under contracts which expire in 2000 and 2012, respectively. The
contracts have price adjustment provisions which are based on the qualities of
coal delivered and changes in indices of mining costs. All of the output from
the Warkworth mine is exported; approximately 80% is sold under contracts,
including contracts with the other joint venture partners in Warkworth, and
approximately 20% is sold on the spot market. Peabody Australia's export
contracts normally provide for annual price renegotiations.
 
        Peabody Australia's Mining Services Division provides specialized
tunneling and underground mining services to the civil engineering and mining
industries.
 
Peabody Development
 
        At March 31, 1997, Peabody Development owned or controlled approximately
3.4 billion tons of Peabody's unassigned proven and probable reserves and
managed approximately 100,000 acres of land. Peabody Development also operates a
computerized land management system which maintains a record of Peabody's US
coal reserves and coal-related land holdings, and is responsible for the
disposal of surplus lands and reserves in the US which no longer have strategic
value. Peabody Development is also responsible for acquiring additional reserves
for the Group, through exploration and the acquisition of additional leases.
 
Other
 
        Peabody owns Patriot Coal Company, which operates a small surface mine
and a small underground mine in western Kentucky, both of which produce high
sulfur coal. The employees of Patriot Coal Company are not unionized.
 
        In addition to the coal interests described above, Peabody owns a one
third interest in Black Beauty Coal Company ("Black Beauty"), the largest coal
producer in Indiana. The remainder of Black Beauty is owned by The

1997, Black Beauty sold approximately 1.5 million tons of low and high sulfur
coal. Two additional mines are under development in Indiana, the annual capacity
of which is expected to be approximately four million tons when they reach full
production later in 1997. The employees of Black Beauty are not unionized.
 
Transportation
 
        Peabody's US customers are generally responsible for arranging and
paying for the transportation of coal from Peabody's mines to the customers'
locations. The majority of Peabody's coal is transported by railway, although
barge, truck, conveyor belts and coal pipelines are also used.
 
        Peabody's US export customers generally take delivery at several port
facilities, including Dominion Terminals Associates, which operates the US's
largest coal export facility in Newport News, Virginia with approximately 24
million tons of annual capacity and which is used to ship coal from Peabody's
West Virginian mines to its export customers. Peabody owns a 30% interest in
Dominion Terminals Associates.
 
        Peabody Australia's exports are shipped through the Port of Newcastle,
where the joint venture company which owns the Warkworth mine owns 4.2% of a
coal loading terminal.
 
Competition
 
        The top ten producers in the US coal industry accounted for
approximately 55% of total US coal production in 1996, although there were an
estimated 981 coal producers in the US in that year. The Group's principal
competitors in its coal operations are other large coal producers, including
certain major oil companies which have extensive coal operations.
 
        The markets in which the Group sells its coal are affected by a number
of factors beyond its control. Continued demand for the Group's coal and the
prices obtained by the Group depend primarily on the coal consumption patterns
of the electricity industries in the US and the Asian Pacific Rim countries, the
availability, location (and therefore the cost of transportation) and the price
of competing coal and alternative electricity generation and fuel supply sources
such as natural gas, oil, nuclear and hydroelectric. Coal consumption patterns
are affected primarily by the demand for electricity, environmental and other
governmental regulations and technological developments. In addition, the
Directors believe that the continuing deregulation of US electric utilities,
which accounted for approximately 91% of Peabody's sales by volume in the year
ended September 30, 1996, will continue to cause such utilities to be more
aggressive in negotiating with coal suppliers. In recent years there has been
excess coal production capacity in the US due to increased development of large
surface mining operations in the western US, more efficient mining equipment and
techniques, and reduced consumption of high sulfur coal. Competition resulting
from excess capacity tends to cause producers to reduce prices and to pass
productivity gains achieved at the mines through to customers. Peabody competes
on the basis of coal quality, delivered price, customer service and support and
reliability.
 
        In the six years ended December 31, 1996, Australian saleable coal
production increased by approximately 18.5%. Total Australian coal production
rose approximately 3.4% in 1996 and the top ten producers in the Australian coal
industry accounted for approximately 79% of total Australian production in that
year. The Group's Australian competitors are principally coal companies owned by
large mining or oil producing companies, although one of the top ten competitors
is a state-owned enterprise.
 
POWER
 
        The Group's power business comprises three core activities: the
generation of electricity, the sale of electricity and the sale of natural gas.
This combination of integrated activities within the electricity and gas
industries provides the Group with opportunities to benefit throughout the
electricity and gas supply chains, from fuel sourcing to customer sales. The
overall financial efficiency of these activities is co-ordinated by the growing
energy trading business of Eastern.
 
        In Great Britain, the Group's power business is:
 
        -      the fourth largest generator of electricity;
 
        -      one of the largest suppliers of electricity and the largest
               supplier of electricity in England and Wales; and
 
                                       12
<PAGE>   88
 
        -      one of the largest suppliers of natural gas after Centrica plc
               (formerly part of British Gas).
 
GENERATION
 
        The Group is the fourth largest generator of electricity in Great
Britain with a share of approximately 11% of total registered generating
capacity of 71,850 MW. It currently owns, operates or has an interest in eight
power stations in Great Britain. It also has a controlling interest in Nedalo
(UK) Limited, the largest supplier of small (up to one MW (electrical)) combined
heat and power ("CHP") plants in the UK, and has a controlling interest in
Teplarny Brno a.s. ("Teplarny Brno"), a heating and generation company in the
Czech Republic.
 
        Further information on the Group's interests in power stations in Great
Britain is set out in the following table:

Seven Year Statement for the years 1996/7 to 2002/3.
 
(1)       All capacity is registered generating capacity except for Peterborough
          and King's Lynn, which have registered generating capacities of 405MW
          and 380MW respectively, but installed generating capacities of 360MW
          and 340MW respectively.
 
(2)       Currently being commissioned and scheduled to commence full commercial
          operation in late 1997.
 
(3)       Registered generating capacity is 1,000MW. The Group holds an interest
          of approximately 13.5%.
 
        The Group's current portfolio of power stations, a mix of combined cycle
gas turbine ("CCGT") and coal-fired stations, represents both base load (running
throughout most of the year) and mid-merit (running in high demand periods)
plants. The inclusion of coal-fired plants within the Group's portfolio of power
stations has enabled the Group to reduce its fuel supply risk. The energy
trading business of the Group is responsible for setting the level of bids into
the Pool for the output of each of its generating stations (other than Barking)
so as to co-ordinate the operation of its generating stations with its fuel
contract position, and its retail and wholesale electricity and gas sales
portfolios. For further information, see "Energy Trading" below.
 
West Burton, Rugeley B and Ironbridge
 
        In June 1996, the Group assumed operational and commercial control, by a
combination of operating lease and outright sale, from National Power, of all of
the assets and liabilities of the West Burton, Rugeley B and Ironbridge power
stations (with the exception of trade and certain other debts and liabilities
outstanding at the date of completion). All existing staff at these stations
were transferred to Eastern, which holds a 99 year lease over the land,
buildings and plant at each of the power stations, and has the right to purchase
the freehold land for a nominal sum after 50 years. Under the leases, Eastern is
committed to aggregate fixed payments totalling L737.5 million, of which L337.5
million was paid at commencement of the leases. The balance, together with
interest, is payable over seven years from 2000. Further payments of
approximately L6 per MWh linked to output levels from these stations are also
payable to National Power for the first seven years of operation.
 
                                       13
<PAGE>   89
 
Drakelow C and High Marnham
 
        The Group has leased, for a period of 99 years, the land, buildings and
plant at the Drakelow C and High Marnham power stations from PowerGen pursuant
to agreements entered into in July 1996. PowerGen is responsible for
decommissioning costs should Eastern decide to close these stations during the
term of the leases. Eastern is committed to fixed payments totalling L230
million (subject to minor adjustments if aggregate capacity falls below certain
threshold) payable in installments (together with interest) over eight years
from 1996. As with the National Power leases, further output-related payments of
approximately L6 per MWh are payable to PowerGen for the first five years of
operation. From August 1, 1997 the Drakelow and High Marnham power stations have
been operated by Eastern.
 
Peterborough
 
        The power station at Peterborough was developed and constructed as a
joint venture between Eastern and Hawker Siddeley Power (Peterborough) Limited
("Hawker Siddeley") between 1990 and 1993. Eastern acquired Hawker Siddeley's
interest in September 1994. The station's gas requirements are sourced from the
Group's gas business. The Peterborough plant is operated and maintained on
behalf of Eastern by a third party contractor under a seven year contract which
commenced in 1993.
 
King's Lynn
 
        A new 340MW CCGT power station at King's Lynn has been constructed for
Eastern under a turnkey contract. The station, which is currently being
commissioned, is scheduled to commence commercial generation in late 1997 and
will be operated and maintained by Eastern. The station's gas needs will be
provided by the Group's gas business.
 
Barking
 
        Eastern has an interest of approximately 13.5% in a 1,000MW CCGT power
station at Barking which became operational in 1995, having been constructed as
a joint venture between Eastern and a number of other companies.
 
Nedalo
 
        The Group owns 75% of Nedalo (UK) Ltd., which provides small scale CHP
equipment of up to one MW (electrical) as a single unit. Nedalo is estimated to
have a share of approximately 80% of the UK market for this equipment.
 
Czech Republic
 
        In November 1996, the Group invested approximately L21 million in
acquiring a controlling interest of 52.8% in Teplarny Brno, a heating and
generation company based in Brno, the second largest city in the Czech Republic.
In 1997 the Group acquired a further 30.4% of the share capital of Teplarny Brno
for L6.6 million. A mandatory offer to purchase from the public the balance of
the share capital of Teplarny Brno will be made by the Group within 60 days
after September 14, 1997 and will be open for acceptance for 60 days thereafter.
Teplarny Brno owns coal and gas plants which are capable of generating 1,204MW
of energy in the form of steam and hot water which is sold principally to
industrial and domestic customers. It also owns a 169 kilometer pipe network for
distributing heat to customers' premises. Teplarny Brno also has an electricity
generation capacity of approximately 97MW, the output of which is sold to the
regional electricity company. A CCGT plant is currently under construction for
Teplarny Brno under a turnkey contract to provide 140MW of additional heat
capacity, and to allow 94MW of additional electricity generating capacity. In
addition, as described under "Networks" below, the Group has acquired a minority
interest in Czech electricity distribution company.
 
Poland
 
        On September 9, 1997 the Group announced that it had agreed (subject to
satisfaction of preconditions) to acquire 49 per cent of Zamosc Energy Company
which is a joint venture with the Polish regional distribution company Zaklod
Energetyczny Zamosc SA and holds the right to develop three 70MW electric
co-generation plants in Chelm, Zamosc and Przemysl in southwest Poland which are
expected to cost approximately US$100 million each to build.
 
                                       14
<PAGE>   90
 
Other Projects
 
        A number of new generation projects are currently under consideration by
the Group including applications for permission to construct and operate two
additional CCGT units at the King's Lynn site to give an additional capacity of
680MW. Eastern is also considering opportunities for large scale CHP plants and
has recently applied for permission to construct a 240MW CHP power station in
conjunction with a major industrial energy user.
 
        Other opportunities for large and small scale CHP plants and renewable
energy projects are actively being considered together with other conventional
generating projects. These include a project to develop a reduced emission coal
fired ("cleaner coal") power station in Great Britain via a joint venture
arrangement.
 
Competition
 
        Eastern was the fourth largest generator in Great Britain as of March
31, 1997, with a share of approximately 10% of total registered generating
capacity. This compares to shares of approximately 26%, 25% and 12% for National
Power, PowerGen and British Energy, respectively. Eastern's mix of generating
plants enables it to operate in the mid-merit and base load sectors of the
market and to spread its fuel risk. Its future competitiveness in the generating
market will be affected by the rate at which it brings new, more efficient,
generating capacity onstream and by the impact of other generators and end-users
themselves building and owning new capacity, including CHP.
 
        Given the current relative costs of various generation technologies, the
Directors believe it is likely that most new generating capacity to be built in
the UK over the next few years will be CCGT. The technology, while capable of
running at either base load or mid-merit, is, in the view of the Directors,
likely to be bid into the Pool so as to run at base load. Such an increase in
base load capacity may encourage larger numbers of existing power stations to
run in mid-merit mode, thereby increasing competition in the sector in which the
Group has recently established itself. However, this may be mitigated to the
extent that older power stations running in mid-merit mode are run down or
closed.
 
Electricity Sales
 
        Eastern supplies electricity to customers in both the franchise market
and the competitive market and is the largest supplier of electricity in England
and Wales.
 
Franchise Market
 
        Eastern Electricity has the largest franchise market in England and
Wales, supplying electricity to over 3 million customers comprising
approximately 2.9 million domestic customers and 250,000 small businesses.

        Eastern Electricity's authorized area covers approximately 20,300 square
kilometers in the east of England and parts of north London.
 
Competitive Market
 
        Eastern is an active participant in the national competitive market.
According to MarketLine International (a research company which produces annual
market statistics on the electricity industry), Eastern has an aggressive
competitive strategy for customer retention. The competitive market currently
comprises over 51,000 sites, which the Directors estimate represents a market
size of approximately L6 billion per annum at current electricity prices. The
Directors estimate that over 50% of the Group's electricity sales to the
competitive market are to customers outside Eastern's authorized area.
 
Competition
 
        Eastern competes in the competitive market on the basis of quality of
customer service and by competitive pricing. According to MarketLine
International, Eastern's market share for the twelve months ended March 31, 1997
was approximately 9.3% by sales volume and 14.1% by number of sites, making it
one of the leading competitive market suppliers among the PES License holders.
The largest suppliers in the competitive market over the same period were
PowerGen and National Power.
 
        Eastern is currently the largest franchise market supplier in Great
Britain, supplying electricity to over three million customers in its authorized
area and is currently scheduled to remain the sole supplier of electricity to
those customers until March 31, 1998, after which competition for customers in
all areas of Great Britain is expected to be progressively phased in. The full
consequences of such deregulation are unpredictable, including the extent to
which new entrants who are not PES License holders will enter the supply market,
the impact of price competition, if any, and customers' propensity to change
suppliers. There can be no assurance that competition among suppliers of
electricity will not adversely affect the Group. The Group intends to continue
to compete for customers nationally following the introduction of such
competition.

Energy Trading
 
        Typically, PES License holders are exposed to risk, as they are obliged
to supply electricity to their customers at stable prices, but have to purchase
almost all the electricity necessary to supply those customers from the Pool at
prices which are constantly changing. This potential risk is hedged through the
use of financial instruments such as Contracts for Differences ("CfDs"). In
addition, the ownership of generating assets provides a hedge to this risk.
 
        A CfD is an agreement between two parties calling for payments between
the parties in amounts equal to the product of (a) the difference in each
settlement period between the Pool price and the price ("strike price")
specified in the CfD and (b) the amount of electricity provided for in that
settlement period which is usually expressed in MW of demand. The settlement
period is half an hour. CfDs effectively fix the prices a supplier pays and a
generator receives for electricity and therefore reduce the financial risk
otherwise associated with the sale and purchase of electricity through the Pool.
 
        The energy trading business co-ordinates the Group's activities in
managing risk and provides support to Eastern's electricity and natural gas
retail activities. The Group's risk management activities are also fully
integrated with its natural gas purchase and sales, wholesale and trading
contract portfolios to ensure that the operation of Eastern's power stations is
optimized having regard to relative prices in gas and electricity markets. The
energy trading business also earns revenue by providing risk management services
to other retailers of electricity aimed at removing or reducing their Pool price
risk.
 
        Eastern seeks to manage its financial exposure by trading its portfolio
of CfDs (a small number of which are long-term), bidding Eastern's generation
output into the Pool, in terms of both price and volume, for each half hour of
the day, and by agreeing with the electricity sales division the volume and
pricing of sales in the competitive market. The overall position for each half
hour of the day is monitored by the energy trading business with the aim of
balancing electricity purchases and sales, although the inflexibility of CfDs
available in the market and the physical availability of plant means that an
exact balance for every half hour cannot be achieved. The resulting net position
is subject to risk exposure limits which are monitored independently within
Eastern. Credit checks are also undertaken on counterparties. Although to date
Eastern has successfully managed such risk through management operations and has
reduced its exposure to this risk by building and leasing generation assets,
Eastern's ability to manage such risk in the future will depend, in part, on the
terms of its supply contracts, its ability to implement and manage an
appropriate hedging strategy, the continuation of an adequate market for hedging
instruments and the performance of its generating assets.
 
        The energy trading business purchases coal, oil and natural gas for the
Group's UK power stations and has small equity interests in three natural
gas-producing fields in the North Sea. It also coordinates the purchase and sale
of natural gas on a long and short term basis.
 
        As part of the Group's strategy to exploit opportunities in energy
trading services with third parties, in December 1996, Eastern entered into
agreements with Enron Capital & Trade Resources Limited ("Enron") to provide
certain energy management services to Enron in connection with its proposed new
790MW power station at Sutton Bridge in Lincolnshire. Subject to the
satisfaction of certain conditions precedent, the arrangements will come into
effect in mid-1999 coincidental with scheduled commencement of full operation of
the power station, and will expire 15 years later. Eastern has also agreed to
purchase up to 475 million therms of gas per annum from Enron over the 15 year
term commencing in mid-1999 at prices related to the prevailing market price for
gas at the time, the daily volume of gas supplied being dependent on the
relative market prices of electricity and gas. Under these arrangements, Eastern
may either use this gas in its portfolio or sell some or all of it back to
Enron, the resale volume being related to an associated electricity purchase
agreement. The electricity purchase agreement will, in turn, form another
element in Eastern's electricity portfolio. Overall, these arrangements provide
Eastern with additional flexibility in the management of its energy portfolio as
a whole.
 
        On April 9, 1997 Eastern entered into an energy conversion arrangement
with Rolls Royce Power Ventures Ltd to provide natural gas and take the
electricity output from a mid-merit approximately 100MW gas fired power station
subject to receiving formal consent from the Office of Electricity Regulation
("OFFER"), which has been approved in principle, and other preconditions.
 
        In order to help meet the expected needs of its natural gas wholesale
and retail customers (including the Group's power stations), Eastern has entered
into a range of purchase contracts. As of June 30, 1997, the commitments under
long-term purchase contracts amounted to an estimated L3.0 billion covering
periods of up to 18
 
                                       17

years from such date. Firm sales commitments (including estimated power station
usage) at the same date amounted to L3.0 billion, covering periods up to 18
years from such date.
 
Energy Marketing
 
        The Group acquired Citizens in May 1997 for an initial cash payment of
$20 million, plus a payment due on March 31, 2000 equivalent to the net assets
of the Citizens companies as of June 30, 1997. In addition, the Group is
required to pay additional amounts based on the achievement of profit goals up
to 2002, subject to a maximum payment for the entire transaction of $120 million
(including the net asset payment).
 
        Citizens, which is headquartered in Boston and employs approximately 100
persons, engages in the purchase, sale and marketing of physical electric power
and transmission rights; the structuring and trading of electricity, gas and
fuel-related risk management products; the restructuring of power sales and
power supply agreements between third party sellers and purchasers; and the
marketing of Orimulsion(R) (a Venezuelan boiler fuel). In the year ended
December 31, 1996, prior to its acquisition by the Group, Citizens had gross
profit of $21.5 million and operating profit of $5.3 million.
 
        Through Citizens Power Sales, Citizens was the fifth largest independent
wholesale electricity marketer in the US during 1996. Citizens purchases and
resells wholesale electric power and designs and applies electricity risk
management tools which include purchases and exchanges of electric capacity
and/or energy; banking, storage, and swaps of physical electricity; swaps of
fuel and electricity; forward purchases of fuel and electricity; and floors,
caps and collars on electricity and fuel pricing. It also engages in fuel to
electricity tolling transactions and electricity/fuel exchanges.
 
        Citizens, through its subsidiaries Hartford Power Sales, L.L.C. ("HPS"),
CL Power Sales One, L.L.C. ("CL One"), CL Power Sales Two, L.L.C. ("CL Two"),
and CL Power Sales Eight, L.L.C. ("CL Eight"), has conducted the restructuring
of power sales agreements between several non-utility generators and electric
utilities in the northeastern US. Citizens is currently pursuing additional
restructuring opportunities throughout the US.
 
        In connection with the Offer by PacifiCorp, Citizens filed an
application to sell Citizens Power Sales and other subsidiaries of Citizens to
Lehman Brothers Holdings, Inc ("Lehman"). Since these entities have received
authorization from the Federal Energy Regulatory Commission (the "FERC"),
transfer of control of these entities is subject to further approval by the
FERC.
 
        The sale of these assets to Lehman is not expected to be completed
unless and until a further offer for Energy is made by PacifiCorp. If the sale
were to take place, it is anticipated that Lehman would purchase Citizens Power
Sales for the amount of $10 million, to be financed by a non-recourse
non-interest bearing note payable to Citizens out of the cash flows of and
proceeds from the disposition of assets of Citizens Power Sales. Citizens would
also receive 80% of the proceeds in excess of the principal amount of the note.
A separate purchase price would be established for each of the other companies
sold, which would be financed by non-recourse notes payable solely out of cash
flows or proceeds from the sale of the projects owned by those companies.
 
NATURAL GAS RETAILING
 
        The Group, through Eastern Natural Gas and its subsidiaries, is one of
the largest suppliers of natural gas in Great Britain after Centrica plc. The
Directors estimate that as of March 31, 1997 the Group's market share by volume
was approximately 11% of gas delivered to the competitive industrial and
commercial market, an increase from approximately 5% as of March 31, 1996.
 
        The Group is taking advantage of the increased competition progressively
being introduced into the industry by the British Government. It currently has
approximately 100,000 customers in the UK at 120,000 sites, ranging from
domestic households to large industrial companies. The Group's move into the
domestic sector has included supplying customers in the pilot deregulation
scheme in southwest England which began in April 1996 and has since been
extended to other counties in the south of England in the first half of 1997 and
to Scotland and the northeast of England in the second half of the year.
 
Competition
 
        The gas supply market is highly competitive, with the Group's main
competitors being Centrica plc and the gas marketing arms of certain major oil
companies. Further competition is provided by a number of other electricity
 
                                       18
<PAGE>   94
 
companies and smaller gas suppliers which are independent of the major oil
companies and which each have a minor presence in the market.
 
        In the six months ended March 31, 1997, the Directors estimate that the
Group maintained its market share of the retail gas supply market (by volume) at
11%. The Group aims to maintain a significant share of this market through
high-quality customer service and competitive pricing, and also utilizing the
economics of scale that its current level of sales provides in purchasing gas.
 
NETWORKS
 
ELECTRICITY
 
        Almost all electricity customers in Eastern's authorized area, whether
franchise or competitive, are connected to and dependent upon Eastern's
distribution system. Eastern distributes approximately 31TWh of electricity
annually to over three million customers, representing more than seven million
people. The majority of the Group's owned tangible fixed assets in the UK are
currently employed in the electricity distribution business. The distribution by
Eastern of electricity in its authorized area is regulated by its PES License,
which, save in exceptional circumstances, is due to remain in effect until at
least 2025.
 
Physical Distribution System
 
        Eastern receives electricity from the National Grid at 21 supply points
within its authorized area and three points in the authorized areas of
neighboring RECs. The majority of this electricity is received at 132kV. It is
then distributed to customers through the Group's system of approximately 35,600
kilometers of overhead line, 53,100 kilometers of underground cable, and
numerous transformers and switchgear, via a series of interconnected networks
operating at successively lower voltages. Eastern also receives electricity
directly from power stations located in its authorized area and, from time to
time, from customers' own generating plants and connections with neighboring
RECs.
 
Customers
 
        Networks derived approximately 91% of its use of system revenue in the
six months ended March 31, 1997 from Eastern's electricity sales operations. The
remaining 9% was derived from holders of Second Tier Supply Licenses in respect
of the delivery of electricity in those of their customers located in Eastern's
authorized area.
 
System Performance
 
        The performance of the network is monitored and publicly reported upon
annually by OFFER. According to recent figures, in the year ended March 31,
1996, Eastern achieved the best overall distribution system performance (number
of faults per 100 kilometers of network) of all the PES License holders. It also
achieved one of the best performances for supply restoration following a fault
and reduced the average time a customer was off supply during a fault.
 
Distribution Charges and Price Control
 
        The distribution charges levied by Eastern and the other RECs consist of
use of system charges and charges for other "excluded services" (i.e., services
outside the scope of the price control) including connection charges.
Distribution and supply charges are regulated by certain conditions in Eastern's
PES License, which sets out a formula for determining the maximum charge per
unit distributed in any financial year. A substantial majority of the sales of
the Group's electricity network business consists of charges for the use of its
distribution system, most of which are charged to its Power business and are
passed through to its customers. Most of the charges for the use of the
distribution system are subject to distribution price controls. See "Regulatory
Matters" below.
 
Czech Republic
 
        In October 1996, the Group acquired a minority interest in
Severomoravska Energetika a.s., a Czech electricity distribution and supply
company, as part of its plan to develop interests in companies that would enable
it to implement further its integrated energy strategy overseas. As described
under "Generation", the Group acquired an interest in Teplarny Brno, a heating
and generation company in the Czech Republic, in November 1996 and subsequently
increased its interest during 1997.
 
                                       19
<PAGE>   95
 
Competition
 
        At present, the Group experiences little competition in the operation of
its electricity distribution system. However, in certain limited circumstances,
some customers may establish (or increase) capacity for "own generation", by
becoming directly connected to the National Grid or establishing their own
generating capacity, thereby avoiding use of distribution system charges.
 
Telecommunications
 
        The Group's telecommunications network comprises an established radio
telemetry network and a recently constructed optical fiber cable network of
approximately 1,100 kilometers which principally covers Eastern Electricity's
authorized area, but also connects to certain other business centers, including
central London. Extensions in the Kent/Sussex area are currently in planning and
implementation and are expected to increase the network to approximately 1,800
kilometers by 1998. Capacity is made available to large business users, cable
operators and public telephone operators. The Group also holds a public
telephone operations license and runs a radio site sharing the optical fiber
renting operation with a number of major telecommunications companies.
 
Contracting
 
        Eastern's Contracting Division provides electrical contracting services.
These services, to domestic, commercial and industrial customers (including
other PES License holders) for voltages up to and including 132kV, involve the
design, installation and maintenance of heating, security, fire alarm and
prevention, power generation and standby systems, overhead lines, switchgear and
electrical wiring systems. Eastern is in competition with other electrical
contractors, including other RECs.
 
OTHER ACTIVITIES
 
        The Group is involved in a number of other peripheral activities,
including a gold and copper exploration prospect in northern Chile, a landfill
project in Imperial County, California, and the design, manufacture, sale and
lease of modular buildings.
 
        The first two of these are residual activities conducted by the
Consolidated Gold Fields group which was acquired by Hanson in 1989. The
Consolidated Gold Fields group was established in the 1890s to finance gold
mining prospects in Southern Africa. It subsequently diversified into a range of
other activities including mining, extractive and metal processing operations in
various other countries, including the US, the UK and Australia. In addition to
its continuing interests relating to coal mining, and the gold and copper and
landfill projects mentioned above, Consolidated Gold Fields has a number of
other minor and/or non-trading subsidiaries.
 
        The design, manufacture, sale and lease of modular buildings is
conducted by Rollalong, a UK company, which is also a holding company of Eastern
and Consolidated Gold Fields.
 
        For a discussion of certain contingent liabilities relating to certain
former operations of Consolidated Gold Fields, see "Other Regulatory Matters"
below.
 
        The Group also owns Major Insurance Company Limited ("Major"), a company
incorporated in Bermuda, which formerly acted as a captive insurance company for
certain of Hanson's and the Group's existing and previous US businesses. Prior
to the Demerger, the outstanding insurance business of Major was reconfigured,
reinsured or indemnified by other present or former Hanson entities, so that its
continuing business relates only to Peabody's US operations and Consolidated
Gold Fields' US operations.
 
EMPLOYEES
 
        The average number of persons employed by the Group during the six
months ended March 31, 1997 was 15,108, of whom approximately 6,770 were based
in the UK, approximately 6,549 were based in the US, approximately 1,120 were
based in Australia and approximately 669 were based in other countries. As of
March 31, 1997, the total number of employees was 15,025.
 
UNION REPRESENTATION
 
        Approximately 60% of the Group's US coal employees (which produced
approximately 34% of its US sales volume in the six months ended March 31,
1997), all of the Group's Australian coal employees and approximately
 
                                       20
<PAGE>   96
 
62% of the Group's power and networks employees as of March 31, 1997 were
members of unions. Certain of Peabody's competitors in the US have non-union
workforces. Because of the increased risk of strikes and other related work
stoppages, in addition to higher labor costs which may be associated with union
operations in the coal industry, Peabody's non-union competitors may have a
competitive advantage in areas where they compete with Peabody's unionized
operations.
 
        The workers at Peabody East (approximately 3,010 at March 31, 1997) are
represented by the United Mine Workers of American Union (the "UMWA") and work
under the 1993 National Bituminous Coal Wage Agreement (the "NBCWA"), a
multi-employer agreement negotiated by the Bituminous Coal Operators'
Association (the "BCOA") of which Peabody East is a member. The NBCWA became
effective on December 15, 1993 and is due to expire on August 1, 1998, although
negotiations to extend the contract beyond that date are expected to begin later
in 1997. The previous multi-employer agreement covering the workers at Peabody
East, the National Bituminous Coal Wage Agreement of 1988, expired in February
1993. A new agreement had not been reached when the agreement expired and the
union immediately called a strike. Except for a 60 day period in March and April
1993, the strike continued until December 1993 when the current NBCWA was
signed. The Directors estimate that this resulted in lost profits of L100
million to L120 million in the year ended September 30, 1993 and L70 million to
L80 million in the year ended September 30, 1994. During the 1993 dispute, the
main demands by the UMWA included (a) automatic unionization of new mines opened
by Peabody; (b) rights to non-union jobs; and (c) rights to all jobs available
whenever a new mine was opened by Peabody. Although the BCOA would not agree to
these demands, the parent companies of the BCOA members signed individual
Memoranda of Understanding which gave the UMWA members the right to the first
three out of every five new jobs at non-union bituminous mines. This currently
affects two mines operated by Peabody. The NBCWA provided for two reopener
provisions to be exercised by the UMWA and the BCOA between September and
December 1996 and September and December 1997. Under the reopener provisions,
wages, pensions and medical benefits could be renegotiated. The BCOA settled
both reopeners early in August 1996. The settlements provide for increases in
wages (on a lump sum basis) and pensions and a lower medical deductible. Peabody
East has enjoyed a good relationship with the UMWA since the NBCWA was signed.
 
        Peabody Western employees (approximately 723 at March 31, 1997) are
covered by the Western Surface Agreement of 1992. This agreement was due to
expire in May 1997, but has been extended to August 2000. Peabody Western was
not affected by the strikes in 1993 and no significant production has been lost
at Peabody Western since 1987 as a result of industrial action. No assurance can
be given that the existing NBCWA and the Western Surface Agreement will be
successfully renegotiated upon their expiration without a strike or other work
stoppage. Apart from work stoppages which may occur upon termination of a
collective bargaining agreement, Peabody East and Peabody Western may from time
to time be subject to certain unauthorized work stoppages or wildcat strikes.
 
        The Australian coal mining industry is highly unionized and all the
workers employed at Peabody Australia are members of trade unions. These
employees are represented by three unions, the United Mine Workers which
represents the production employees, and two unions which represent the other
staff. The miners at Warkworth mine have signed a three year labor agreement
which is due to expire in September 1999 and the miners at the Ravensworth and
Narama mines have signed a two year labor agreement which will expire in March
1998. Although production is lost due to industrial action from time to time, in
recent years there have not been any significant disputes or stoppages at mines
operated by Peabody Australia.
 
        Eastern recognizes trade unions for collective bargaining purposes and
approximately 66% of employees of Eastern's businesses are union members.
Eastern Natural Gas and the energy trading businesses do not recognize trade
unions and most workers in these businesses are employed under individual
contracts. There have been no industrial disputes or work stoppages at Eastern
since its privatization in 1990. Eastern has negotiated a two year agreement
relating to pay with employees in the electricity supply and networks businesses
which expires at the end of June 1998.
 
REGULATORY MATTERS
 
        The Group's operations are subject to extensive and changing regulation
in the UK, the US and Australia regarding production, sale, distribution, health
and safety and environmental matters.
 
                                       21

REGULATORY MATTERS AFFECTING PEABODY
 
US
 
        The US coal mining industry is subject to regulation by federal, state
and local authorities on matters such as employee health and safety, permitting
and licensing requirements, air quality standards, water pollution, plant and
wildlife protection, the reclamation and restoration of mining properties after
mining has been completed, the discharge of hazardous substances into the
environment, surface subsidence from underground mining and the effects of
mining on groundwater quality and availability. Costs associated with such
regulatory compliance increase the overall cost of mining. While it is not
possible to quantify the costs of compliance with all applicable federal and
state laws, those costs have been and are expected to continue to be
significant. For a discussion of the costs associated with the Group's health
care obligations to employees, reclamation and environmental obligations, see
Notes 19 and 21 of Notes to the Financial Statements included herein.
 
Mining Health and Safety
 
        Stringent health and safety standards have been imposed by federal
legislation since the Federal Coal Mine Health and Safety Act of 1969 was
adopted. That Act resulted in increased operating costs and reduced
productivity. The Federal Mine Health and Safety Act of 1977 significantly
expanded the enforcement of health and safety standards and imposed health and
safety standards on all aspects of mining operations.
 
        Most of the states in which Peabody operates have state programs for
mine health and safety regulation and enforcement. In combination, federal and
state health and safety regulation in the coal mining industry is a very
comprehensive and pervasive system for protection of employee health and safety.
This regulation has a significant effect on Peabody's operating costs. However,
Peabody's US competitors are subject to the same degree of regulation. Peabody's
accident rate has fallen by approximately 58% during the period from October 1,
1990 to March 31, 1997.
 
Black Lung
 
        Under the Black Lung Benefits Revenue Act of 1977 and the Black Lung
Benefits Reform Act of 1977, as amended by the Black Lung Benefits and Revenue
Amendment Act of 1981, each coal mine operator is required to secure payment of
federal black lung benefits to claimants who are current and former employees
and to a trust fund for the payment of benefits and medical expenses to
claimants who last worked in the coal industry prior to July 1, 1973. Less than
7% of the miners currently seeking federal black lung benefits are awarded such
benefits by the federal government. The trust fund is funded by an excise tax on
coal sales which is passed on to the purchaser under many of Peabody's coal
sales agreements. The maximum fee is $1.10 per ton on underground mined coal and
$0.55 per ton on surface mined coal.
 
        The US Department of Labor has proposed new regulations which would
liberalize the procedures used to award federal black lung benefits. If the
proposed regulations are finally adopted by the Department of Labor, there is
expected to be a substantial increase in the number of miners that are awarded
federal black lung benefits and Peabody's liability for federal black lung
benefits is likely to increase.
 
Coal Industry Retiree Health Benefit Act of 1992 ("Health Benefit Act")
 
        The Health Benefit Act was enacted to provide for the funding of health
benefits for certain UMWA retirees and their spouses. The Health Benefit Act
established a fund into which "signatory operators" and "related persons" are
obliged to pay annual premiums for beneficiaries. The Health Benefit Act also
created a second benefit fund ("1992 Fund") for miners who retired between July
21, 1992 and September 30, 1994 and whose former employers are no longer in
business. Companies which are signatories to the NBCWA labor agreement must pay
premiums to the 1992 Fund. Peabody East made payments under the Health Benefit
Act of $4.17 million for the six months ended March 31, 1997 and expects that
total payments for the year ending March 31, 1998 will be approximately $8.4
million. These payments are less than half of the amounts paid prior to the
enactment of that Act.
 
Environmental Laws
 
        Peabody is subject to various federal and state environmental laws.
These laws require approval of many aspects of coal mining operations, and both
federal and state inspectors regularly visit Peabody's mines and other
facilities to ensure compliance.
 
                                       22
<PAGE>   98
 
        A risk of environmental liability is inherent in the coal mining
operations of the Group with respect to both current and past operations. The
Group has incurred and will continue to incur expenses for environmental
matters, including those arising from sites relating to former operations or
corporate predecessors of the Group.
 
        Surface Mining Control and Reclamation Act:  The Surface Mining Control
and Reclamation Act of 1977 ("SMCRA") requires coal mining companies to reclaim
land after mining has been completed. The mine operator must submit a bond or
otherwise secure performance of its reclamation obligations. Peabody has $629
million of reclamation bonds in place which assure compliance with all
applicable regulations.
 
        Permits for surface mining operations are obtained from the Federal
Office of Surface Mining Reclamation and Enforcement or, where state regulatory
agencies have adopted federally approved state programs under SMCRA, the
appropriate state regulatory authority. Mining permits issued pursuant to SMCRA
must be renewed. The renewal of a mining permit may be denied if there are
violations of SMCRA, or other environmental laws. Although the Group does not
anticipate permit renewal problems, there can be no assurance that Peabody's
mining permits will be renewed in the future. In addition, the Peabody Western
Black Mesa Mine has been operating under a temporary permit since 1978. The mine
has been operating continuously since 1978, and the Group does not anticipate
that the temporary permit status will have an effect on operations at this mine.
There can be no assurance, however, that Peabody will be allowed to continue
operating under this temporary permit in the future, or that other permit issues
will not arise which will adversely affect Peabody's operations.
 
        SMCRA also imposes a tax on coal production to pay for reclamation of
lands mined prior to 1978. The maximum fee is $0.35 per ton on surface mined
coal and $0.15 per ton on underground mined coal. Under many of the coal sales
agreements to which Peabody is a party, the fee is passed on to the purchaser.
Peabody accrues for the liability associated with all end of mine reclamation on
a ratable basis as the coal reserve is being mined. Peabody has won numerous
national and state awards for its reclamation practices. Accrued obligations
were $444.3 million and $429 million for the year ended September 30, 1996 and
the six months ended March 31, 1997, respectively.
 
        Clean Air Act:  The Clean Air Act, including the Clean Air Act
Amendments of 1990, extensively regulates the air emissions of coal-fired
electric power generating plants. Title IV of the Clean Air Act Amendments
places limits on sulfur dioxide emissions from electric power generation plants.
The first phase ("Phase I") of reductions, which became effective on January 1,
1995, applies to certain identified facilities. The second phase, which will
became effective in 2000 ("Phase II"), applies to all facilities including those
subject to the 1995 restrictions. The affected utilities will be able to meet
these requirements by switching to lower sulfur fuels, by installing pollution
control devices such as scrubbers, by reducing electricity generating levels or
by purchasing or trading so-called "emission allowances". Specific emissions
sources may use these allowances, which utilities and industrial concerns can
trade or sell, to allow other units to emit higher levels of sulfur dioxide.
 
        Title III of the Clean Air Act Amendments also required certain utility
power plants to reduce their nitrogen oxide emissions with effect from January
1, 1995. The EPA adopted regulations in December 1996 requiring the remaining
utility power plants to reduce their nitrogen oxide emissions. Although
Peabody's customers are affected by these regulations, based on current
information, the Directors do not expect any material loss of sales as a result
of these nitrogen oxide regulations.
 
        The EPA announced in July 1997 that it had adopted changes to the
National Ambient Air Quality Standards ("NAAQS") for particulate matter ("PM")
and ozone ("O(3)"). The NAAQS are set at the level judged to protect the
public's health and welfare. The states will be required to implement changes to
their existing plants to attain and maintain compliance with the revisions to
the standards. Because mining operations emit PM and the electric utility
industry emits sulfur dioxide and nitrogen oxides, which are precursors to PM
and O(3), Peabody's mining operations and electric utility customers are likely
to be affected when the revisions to the NAAQS are implemented by the states.
The extent of such effects, which could be material to Peabody, will depend on
the policies and control strategies associated with the state implementation
process under the Clean Air Act. The impact, if any, on Peabody is unlikely to
occur until after 2000.
 
        Comprehensive Environmental Response, Compensation and Liability Act of
1980 ("CERCLA"): CERCLA and similar state laws affect coal mining operations by
imposing clean-up requirements for threatened or actual releases of hazardous
substances that may endanger public health or welfare or the environment. Under
CERCLA, joint and several liability may be imposed on waste generators, site
owners and operators and others regardless of fault or the legality of the
original disposal activity. Waste substances generated by coal mining and
processing are generally not regarded as hazardous substances for purposes of
CERCLA.
                                       23
<PAGE>   99
 
        Clean Water Act:  The Federal Water Pollution Control Act, as amended by
the Clean Water Act of 1977, affects coal mining operations by imposing
restrictions on effluent discharge into water. Regular monitoring, reporting
requirements and performance standards are preconditions for the issuance and
renewal of permits governing the discharge of pollutants into water.
 
        Resource Conservation and Recovery Act:  The Resource Conservation and
Recovery Act ("RCRA") of 1976, affects coal mining operations by imposing
requirements for the treatment, storage and disposal of hazardous wastes. Coal
mining operations covered by SMCRA permits are exempted from regulation under
RCRA by statute. However, the EPA is considering the possibility of expanding
regulation of mining wastes under RCRA. Any changes in the types of substances
regulated under RCRA could have a material adverse effect on the Group's
business or financial position.
 
        Global Climate Change:  The US, Australia and 165 other nations have
signed and ratified the UN Framework Convention on Climate (the "Convention"),
under which the US, Australia and 34 other developed countries have agreed to
implement measures aimed at reducing their greenhouse gas emissions to 1990
levels by 2000. The parties to the Convention are currently working on a further
protocol that is expected to commit the developed nations to adopt policies and
measures and set quantified emission limitations and reduction objectives for
implementation no earlier than 2005. That protocol is expected to be completed
at the end of 1997. Any new protocol adopted by the parties to the Convention
would have to be ratified by the US Senate and the Australian Government before
it became effective in their respective countries. It is unclear what impact
this protocol might have on Peabody's operations, and there is no guarantee that
such impact will not have a material adverse effect upon the Group's business or
financial position.
 
AUSTRALIA
 
        The Australian mining industry is regulated by Australian federal, state
and local governments with respect to environmental issues such as land
reclamation, water quality, air quality and noise, planning issues such as
approvals to expand existing mines or to develop new mines and health and safety
issues. The Australian federal government retains control over the level of
foreign investment, export approvals and industrial relations. Australian state
governments also require coal companies to post security deposits against land
which has been used for mining, which are refundable after satisfactory
rehabilitation.
 
REGULATORY MATTERS AFFECTING EASTERN
 
        The electricity industry in Great Britain is subject to regulation,
inter alia, under the Electricity Act and certain UK and EU environmental
legislation. The Group is also subject to existing UK and EU legislation on
competition and regulation in its gas and telecommunications businesses. In
addition, an element of any profit received by Eastern on its disposal of
certain categories of the assets vested in it at the time of its privatization
is subject to clawback by the Secretary of State for Trade and Industry until
March 31, 2000.
 
        In June 1997, the UK Secretary of State for Trade and Industry announced
a review of utility regulation (including price controls) covering gas,
electricity, water and telecommunications. If an internal governmental review
team concludes that change is needed, the Government has stated that it intends
to publish a consultation paper in the fall of 1997. This review may result in
significant changes to the existing regulatory regime. There can be no assurance
regarding the impact of those potential utility regulatory changes, if any, on
Eastern and the Group.
 
POWER LICENSES
 
Generation
 
        Unless covered by an exemption, all electricity generators operating a
power station in Great Britain are required to have a Generation License. The
conditions attached to such a license in England and Wales require the holder,
among other things, to be a member of the Pool and to submit relevant generating
sets for central dispatch. Failure to comply with any of the Generation License
conditions may subject the licensee to a variety of sanctions, including
enforcement orders by the Director General of Electricity Supply in Great
Britain ("DGES"), or license revocation if an enforcement order is not complied
with.
 
        The Secretary of State has power under the Electricity Act to require
generators operating power stations with a capacity of not less than 50MW to
maintain stocks of fuel and other materials at power stations. The Secretary of
State is currently reviewing the level of fuel stocks held by generators.
 
                                       24
<PAGE>   100
 
        In England and Wales, each PES License limits the extent of the
generation capacity in which the relevant REC may hold an interest without the
prior consent of the DGES ("own-generation limits"). These own-generation limits
currently restrict the participation by a REC in generation to a level of
approximately 15% of the simultaneous maximum electricity demand in that REC's
authorized area at privatization, setting Eastern's limit at 1,000MW. Following
a process of consultation on the own-generation limits, the DGES stated in
January 1995 that he would be prepared to consider a REC's request to increase
its generation capacity on condition that it accepted explicit restrictions on
the contracts it signed with its supply business, and that at a minimum it would
be prohibited from passing additional own-generation output into its franchise
market. In August 1995, he published model draft license modifications which he
indicated that he would consider proposing in connection with a relaxation of
own-generation limits of a REC.
 
        In June 1996, the DGES stated that he had indicated to Eastern that he
would consider relaxing its own-generation limits, subject to agreeing license
modifications as set out in his consultation paper of August 1995. The specific
consent of the DGES to the leasing by Eastern of generating capacity from each
of National Power and PowerGen has been confirmed by OFFER, and the Directors
expect consent to be granted on a conditional basis in relation to the Shotton
CCGT and the Dowlais clean coal plants.
 
Electricity Sales
 
        Subject to certain exceptions, each supplier of electricity in the
franchise market in Great Britain is required to have a PES License for its
authorized area and is required under the Electricity Act to provide a supply of
electricity upon request to any premises in that area, except in specified
circumstances. Each PES License holder is subject to various obligations under
its PES License, including prohibitions on cross-subsidy between its various
regulated businesses and on discrimination in respect of the supply of
customers. Each PES License holder is also required to offer open access to its
distribution network on non-discriminatory terms. This obligation includes a
requirement not to discriminate between its own supply business and other users
of its distribution system. PES License holders are subject to separate revenue
controls on the actual costs they may pass through for the supply of electricity
to franchise customers and in respect of distribution charges.
 
        A supplier of electricity to the competitive market in Great Britain
must, subject to certain exemptions, possess a Second Tier Supply License, or
hold a PES License for the authorized area in which customers are supplied.
 
        Supply charges in the franchise market are regulated by an (RPI-X)+Y
revenue control formula. The RPI-X element relates to the costs of the supply
business, and includes a profit element. For the current control, which was set
for the period April 1994 to March 1998, X has been set at 2%. The Y factor
enables each PES License holder to pass through to customers costs already
regulated (transmission and distribution costs) and certain costs which are
unregulated (electricity purchase costs and the Fossil Fuel Levy). The formula
takes a forward-looking approach and therefore includes a correction factor to
allow for forecasting errors.
 
        The DGES is currently reviewing with the PES License holders, the supply
price restraints to apply to tariff customers from April 1, 1998, when the
process of opening up competition in the under 100KW market is due to begin. The
DGES intends to publish final proposals in early October 1997.
 
Energy Trading
 
        Eastern Power and Energy Trading Limited ("EPETL") is authorized by the
Securities and Investments Board under the Financial Services Act 1986 to deal
in electricity contracts for differences (including futures and options). A
subsidiary of EPETL is a joint holder of production licenses relating to its
equity interest in three North Sea natural gas fields described above.
 
Energy Marketing
 
        The purchasing, wholesaling, and transmission of electricity in the US
is regulated by the FERC. Citizens Power Sales has been authorized by the FERC
to engage in wholesale electric power and energy transactions as a marketer of
electricity at rates established by agreement between Citizens Power Sales and
the purchaser. Citizens Power Sales is obligated to notify the FERC of any
changes in status, including ownership of generation or transmission facilities
or affiliation with any entity that has generation or transmission facilities or
a franchised service area in the US. Each of HPS, CL One, CL Two and CL Eight
has received the same authorization from the FERC and is under the same
obligation to advise the FERC of any changes in status.
 
                                       25
<PAGE>   101
 
        Citizens trades in electricity futures on the New York Mercantile
Exchange. Citizens files periodic reports with the Commodity Futures Trading
Commission.
 
        Restructuring transactions, under which affiliates of Citizens
participate in the restructuring or replacing of power sales agreements between
non-utility generators and utility purchasers, generally require approvals from
state regulatory agencies for the utility purchasers to enter into new power
purchase agreements. Also, long term power purchase contracts from utility
sellers which may be entered into in connection with restructuring transactions
require filing with, and acceptance of filing by, the FERC. These approvals have
been obtained in the restructuring transactions completed to date.
 
        Conversion of generating plants to Orimulsion(R) as a fuel requires
extensive environmental approvals. Final approval for the conversion to
Orimulsion(R) at the 1,600 MW Manatee plant of Florida Power & Light ("FP&L")
was denied by the Florida Siting Board on April 23, 1996. On appeal, the Siting
Board's order was vacated and remanded for reconsideration. On remand, the
Siting Board, on September 9, 1997, by a 5-2 vote, returned the case to the
original hearing officer to consider additional measures to mitigate pollution
and community impacts, which additions are believed acceptable to FP&L. Final
decisions are expected within three months. All other approvals, other than
Siting Board approval, have been obtained by FP&L for the Manatee project.
 
Gas
 
        The gas supply activities on ENG are principally regulated by the
Director General of Gas Supply under the Gas Acts and by the conditions of ENG's
Gas Licenses. ENG currently holds a public gas transporter's license, a gas
supplier's license and a gas shipper's license. The gas business is not subject
to price regulation.
 
NETWORKS
 
Electricity
 
        Approximately 95% of the operating income of Eastern Electricity's
networks business is controlled by a distribution price control formula of
RPI+X(d) which determines the maximum charge per unit that Eastern Electricity
is permitted to charge in any financial year to March 31 for distribution
services which are subject to the control. The X(d) factor for Eastern was
initially related to the numbers of units (kWh) of electricity distributed and
was set at +0.25% for the period 1990 to 1995. Since the distribution price
reviews in August 1994 (effective April 1, 1995) and July 1995 (effective April
1, 1996), price control has been related to the number of customers served and
the number of units sold in equal weightings. These price reviews have resulted
in the X(d) factor being reduced to -11% for 1995/96, -10% for 1996/97 and -3%
for each of the years 1997/98 to 1999/2000. The August 1994 review resulted in
an estimated total reduction of Eastern's prospective revenues of some L350
million over the five years to April 2000 and July 1995 review resulted in an
estimated total reduction of Eastern's revenues of a further L150 million over
the four year period from April 1, 1996 compared with revenue under the previous
distribution price controls. To allow for forecasting errors, an annual
correction factor is built into the control to allow any under-recovery or over-
recovery of income to be recovered in following years, the latter with an
interest penalty. A further distribution price control review is schedule to
take place in 2000. Any additional revenue by the DGES may adversely affect the
Group. Similarly, the DGES may issue further or additional statements or take
further or additional actions which may impact upon the Group's operations.
 
        Distribution costs vary with the voltage at which consumers are
connected and the utilization of the distribution system at the time units are
distributed. Changes in the mix of units distributed at different voltage levels
and between peak and off-peak periods are reflected in the calculation of the
maximum average allowed charge per unit distributed by reference to a "basket"
of distribution categories which take account of the different costs of
distributing electricity at various voltages and at various times of the day.
 
        Electricity distributed to extra high voltage premises is excluded from
the distribution price control formula, as are charges for certain additional
services including connection charges. Connection charges must be set at a level
which enables the licensee to recover no more than the appropriate proportion of
the costs incurred and no more than a reasonable rate of return on the capital
represented by such costs. Any dispute over connection charges may be determined
by the DGES. In addition, income received in respect of National Grid Group exit
charges incurred by a REC and received through use of system charges is not
subject to distribution price control.
 
        In certain circumstances, the DGES may propose amendments to the
distribution price control formula or the terms of the license. In the cases
where a PES License holder is not willing to accept modifications to the
 
                                       26
<PAGE>   102
 
distribution price control formula or other license conditions put forward by
the DGES, the normal process would be for the DGES to refer the matter to the
MMC.
 
Telecommunications
 
        The Group's telecommunications activities are principally regulated by
the Telecommunications Act 1984 and by the conditions of its public telephone
operations license. The UK Secretary of State for Trade and Industry and the
Director General of Telecommunications are the principal regulators of the
telecommunications industry in the UK. The telecommunications business is not
subject to price regulation.
 
ENVIRONMENTAL REGULATIONS AND EMISSIONS
 
        The electricity generation industry in the UK is subject to a framework
of national and EU environmental laws which regulate the construction, operation
and decommissioning of power stations.
 
        Under these laws, each power station operated by the Group is required
to have an authorization which regulates its releases into the environment and
seeks to minimize pollution of the environment taken as a whole, having regard
to the best practicable environmental option.
 
        The responsibility for these requirements in England and Wales is vested
in the Environment Agency ("EA") whose role is to regulate industrial plants and
to monitor the environment, to obtain environmental information and to promote
the objective of sustainable development. When performing its functions, the EA
is required to take into account the best available techniques for controlling
emissions, the life expectancy and rate of utilization of the plant, and the
desirability of not involving excessive cost.
 
        The principal EU Directive affecting environmental emissions currently
in force is the Large Combustion Plants Directive ("LCPD").
 
        The LCPD requires the UK to reduce sulfur dioxide ("SO(2)") emissions
from existing plants by 60% by 2003 and emissions of nitrogen oxides ("NOx") by
30% by 1998 compared with their 1980 levels. The Large Combustion Plant National
Plan is the mechanism by which this directive has been implemented in the UK and
sets year on year programs of reductions for various industries including the
electricity industry. Each site has an annual limit of emissions. Negotiations
are underway regarding further restrictions on emissions.
 
        In addition, the UK has ratified the second United Nations Economic
Commission Sulfur Protocol. The Protocol commits the UK to a reduction in SO(2)
emissions from all sources by 80% by 2010 compared with their 1980 levels.
 
        At a local level, the UK's Air Quality Strategy provides set targets for
2005 and places a duty on local authorities to review air quality with a view to
setting up management in places where targets are not being met. When adverse
meteorological conditions occur, some power stations may have to introduce
measures to comply with these targets.
 
        The UK is also a signatory to the Greenhouse Gases Convention which
commits it to draw up programs aimed at reducing emissions of carbon dioxide and
other greenhouse gases to their 1990 levels by 2000. Negotiations will take
place in December 1997 aimed at cutting emissions further.
 
        For a discussion of the costs associated with environmental matters
affecting the Group, see Item 9 of this Transition Report and Notes 17 and 19 of
Notes to the Financial Statements included elsewhere herein.
 
OTHER REGULATORY MATTERS
 
        Certain US subsidiaries of Consolidated Gold Fields are or may become
parties to environmental proceedings which have been commenced or threatened in
the US in relation to certain sites previously owned or operated by those
subsidiaries or companies associated with them. This includes sites formerly
owned or operated by Consolidated Gold Fields and as well as dormant sites that
the Group currently owns. The EPA has placed some of these sites on the National
Priorities List, promulgated pursuant to CERCLA, and some of these sites are on
similar state priority lists. There are a number of further sites in the US
which were previously owned or operated by such companies which could give rise
to environmental proceedings in which members of the Group could incur
liabilities.
 
                                       27
<PAGE>   103
 
        Where such sites have been identified, the Directors have commissioned a
review of publicly available information by independent environmental
consultants in order to assess the total amount of the liability per site and
the proportion of those liabilities which the members of the Group are likely to
bear. The available information on which to base this review is very limited,
especially in relation to sites which are no longer owned or operated by members
of the Group.
 
        On the basis of that review, the Directors have made a provision against
the above environmental liabilities relating to Consolidated Gold Fields in the
total sum of $73.6 million as of March 31, 1997 (which is included in the
overall provision of L280 million as discussed in Note 19 of Notes to the
Financial Statements included herein), but significant uncertainty exists as to
whether these claims will be pursued against the Group in all cases, and where
they are pursued, the amount of the eventual costs and liabilities. See Note 21
of Notes to the Financial Statements included herein.
 
        In addition to all of the foregoing, the Group may incur environmental
liability and be subject, among other things, to an order requiring the clean-up
of contaminated soils, surface or groundwater, administrative proceedings,
long-term monitoring requirements to evaluate impact on the environment, common
law suits, toxic tort suits, penal proceedings or, in some instances, an
obligation to reimburse governmental agencies or third parties for certain
costs, including natural resource damages.

* Energy was demerged from Hanson and the Ordinary Shares commenced trading on
the LSE and the ADSs commenced trading on the NYSE on February 24, 1997.
 
        As of September 1, 1997, approximately 430,000 Ordinary Shares and ADRs
evidencing approximately 33.3 million ADSs (representing 133.1 million Ordinary
Shares) were held of record in the US. These Ordinary Shares and ADRs were held
by approximately 375 and 18,424 record holders, respectively, and collectively
represented or evidenced approximately 26% of the total number of Ordinary
Shares outstanding. Energy also believes that as of September 1, 1997,
approximately 4% of its outstanding Ordinary Shares were beneficially owned by
US holders. Since certain of these securities are held by brokers or other
nominees, the number of record holders in the US may not be representative of
the number of beneficial holders or of where the beneficial holders are
resident.
 
ITEM 6. EXCHANGE CONTROLS AND OTHER LIMITATIONS AFFECTING SECURITY HOLDERS
 
        There are no UK restrictions on the import or export of capital
including foreign exchange controls that affect the remittances of dividends or
other payments to non-resident holders of Ordinary Shares except as otherwise
set forth in Item 7 of this Transition Report and except for certain
restrictions imposed from time to time by HM Treasury pursuant to legislation,
such as The United Nations Act 1946 and the Emergency Laws Act 1964, against the
government or residents of certain countries.
 
        Except for certain restrictions that may be imposed from time to time by
HM Treasury under legislation as described above, under English law and Energy's
Memorandum and Articles of Association, persons who are neither residents nor
nationals of the UK may freely hold, vote and transfer Ordinary Shares in the
same manner as UK residents or nationals.
 
ITEM 7. TAXATION
 
        The following discussion of taxation is intended only as a descriptive
summary and does not purport to be a complete technical analysis or listing of
all potential tax effects relevant to UK Holders and US Holders of the Ordinary
Shares or ADSs. A US Holder is: (i) a citizen or resident of the US; (ii) a
corporation created or organized in the US under the laws of the US or any
state; (iii) an estate the income of which is included in gross income for US
federal income tax purposes regardless of its source or (iv) a trust if a court
within the United States is able to exercise primary jurisdiction over the trust
and one or more US persons have the authority to control substantial decisions
of the trust. A UK Holder is a person resident or ordinarily resident in the UK
for tax purposes or who is subject to UK taxation on capital gains or income by
virtue of having a trade, profession or vocation in the UK.
 
        The statements of US federal and UK tax laws set forth below are based
on US federal and UK tax laws and UK Inland Revenue practice in force as of the
date of the filing of this Transition Report and are subject to any changes in
UK or US law, and in any double taxation convention between the US and the UK,
occurring after that date.
 
        The following discussion is principally directed at UK tax laws and not
to US tax laws and therefore does not describe all material potential US
federal/or other US/tax consequences. In addition, while this summary is
principally directed to UK tax law, it does not describe all material potential
UK tax consequences. The tax treatment of a shareholder may vary depending on
such shareholder's particular situation, and certain shareholders (including
insurance companies, tax-exempt organizations, dual resident entities, financial
institutions, broker-dealers or entities which, alone or together with one or
more associated corporations, control directly or indirectly more than 10% of
the voting shares of Energy) may be subject to special rules not discussed
below. A US Holder of Ordinary Shares or ADSs should consult its tax advisor in
respect of US tax consequences.
 
        For purposes of the current income tax convention between the UK and the
US (the "Income Tax Convention"), the current estate and gift tax convention
between the UK and the US (the "Estate and Gift Tax Convention") and the US
Internal Revenue Code, holders of ADSs will be treated as the owners of the
underlying Ordinary Shares.
 
TAXATION OF DIVIDENDS
 
UK Holders
 
        Under current UK taxation legislation, no withholding tax will be
deducted from dividends paid by Energy, but whenever Energy pays a dividend, it
will be liable to account to the UK Inland Revenue for an amount of tax
 
                                       30
<PAGE>   106
 
known as advance corporation tax ("ACT"). The rate of ACT is currently equal to
one quarter of the dividend ACT paid by Energy can be set off against its
liability to corporation tax, subject to certain limits and restrictions. If
Energy receives dividends in respect of which ACT has been accounted for and to
which an equivalent tax credit is attached, it will normally be entitled to set
that tax credit against its own liability to account for ACT.
 
        A UK Holder who is a UK resident individual who receives a dividend on
Ordinary Shares or ADSs will be entitled to a tax credit of an amount equal to
one quarter of the dividend. An individual so resident will be taxed on the
total of the dividend and the related tax credit, which will be regarded as the
top slice of such individual's income. The tax credit will, however, be treated
as discharging the individual's liability to income tax in respect of the
dividend, unless and except to the extent that the dividend and related tax
credit exceeds the individual's threshold for the higher rate of income tax. In
such cases the individual will, to that extent, be liable to tax on the dividend
and related tax credit at a rate equal to the excess of the higher rate
(currently 40%) over the lower rate (currently 20%). If the tax credit exceeds
the individual's liability to income tax on the total dividend and tax credit,
the individual will able to claim payment of the excess. Under current
proposals, the rate of tax credit that will be available to UK Holders (other
than UK resident companies or pension providers) in respect of dividends paid on
or after April 6, 1999 will be halved to 10% and tax credits will no longer be
repayable to UK Holders with no tax liability. Under such proposals, individuals
whose income is within the lower or basic rate tax bands will be liable to tax
at 10% on dividend income and the tax credit will continue to satisfy their
income tax liability on UK dividends. It is further proposed that the higher
rate of tax on dividend income will be reduced to 32.5% from April 6, 1999,
which is intended to leave higher rate taxpayers the same amount of after tax
income as they would have received prior to such changes.
 
        Subject to certain exceptions, a UK Holder of Ordinary Shares or ADSs
which is a UK resident company and which receives a dividend paid by the Group
will not be taxable on the dividend. The dividend and related tax credit in
respect of ACT paid on such dividend will be treated as franked investment
income. Such tax credit will be an amount equal to one quarter of the dividend
(although the amount of the tax credit to which the recipient will be entitled
will be reduced to one ninth of the dividend under the provisions. Under current
proposals, pension providers and most UK resident companies will no longer be
entitled to the payment of tax credits in respect of dividends paid to them on
or after July 2, 1997.
 
        Subject to certain exceptions for individuals who are Commonwealth
citizens, citizens of the Republic of Ireland, residents of the Isle of Man or
the Channel Islands, nationals of states which are part of the European Economic
Area and certain other persons, the right of holders of Ordinary Shares or ADSs
who are not resident in the UK for tax purposes to claim payment from the UK
Inland Revenue for a proportion of the tax credit relating to their dividends
will depend, in general, upon the provisions of any double taxation agreement or
convention which exists between the UK and their country of residence.
 
        The above paragraphs do not address the provisions in Chapter VA of Part
VI of the UK Income and Corporation Taxes Act 1988, relating to a dividend which
the paying company elects to be treated as a foreign income dividend ("FID"). In
the future Energy may receive foreign source income. If such circumstances arise
Energy may consider availing itself of the benefits of the FID rules. In the
event that a FID is declared, a UK Holder that is a UK resident company holding
Ordinary Shares or ADSs will not be subject to UK corporation tax in respect of
a FID paid by Energy. The FID will not, however, constitute franked investment
income for such UK Holders. Under current proposals, the rules for payment of
FIDs may be repealed from April 6, 1999.
 
US Holders
 
        Under the provisions of the Income Tax Convention and the Arrangement
(as defined and more fully described below), a US Holder who is an individual or
a corporate portfolio holder (which is defined as a shareholder who holds less
than 10% of the voting shares of Energy) of Ordinary Shares or ADSs will be
entitled to receive from the UK Inland Revenue a refund (the "Tax Treaty
Payment") of an amount equal to the tax credit in respect of ACT minus a
withholding tax of 15% of the sum of the cash dividend plus the tax credit. The
rate of ACT is currently 25% of the cash dividend paid. On the basis of an ACT
rate of 25% of the dividend, a L80 dividend (which amount and rate of ACT have
been selected for illustrative proposes only) would result in a L20 payment of
ACT by Energy. The tax credit related to the dividend would be equal to L20 (20%
of the sum of the L80 dividend and the L20 tax credit). The US Holder who is an
individual or corporate portfolio would be entitled to receive a L5 Tax Treaty
Payment, calculated by reducing the L20 tax credit by withholding tax of L15
(15% of the sum of the L80 dividend and the L20 tax credit). Accordingly, such
US Holder would have a total net receipt of L85 (cash dividend of L80 plus a net
tax credit of L5). Under current proposals the rate of tax credits will be
halved from 20% to 10% on dividends paid on or after April 6, 1999 with the
result that a US Holder who is an individual or a corporate portfolio holder
would not be entitled to receive any Tax Treaty Payment.
                                       31
<PAGE>   107
 
        A US Holder of Ordinary Shares of ADSs nonetheless will not be entitled
to claim the Tax Treaty Payment described above if: (i) the holding of Ordinary
Shares of ADSs is effectively connected with (a) a permanent establishment
situated in the UK through which the US Holder carries on business in the UK, or
(b) a fixed base in the UK from which the US Holder performs independent
personal services; or (ii) in the case of a US Holder that is a US corporation,
the US Holder is (a) also a resident of the UK, or (b) in certain circumstances,
an investment or holding company at least 25% of the capital of which is held,
directly or indirectly, by persons that are not individual residents or
nationals of the US. Further, special rules may apply if the US Holder is exempt
from tax in the US on dividends paid by Energy. The refund may not be available
in the case of a US Holder who owns 10% or more of the class of shares in
respect of which the dividend is paid to the extent that the dividend can only
have been paid out of profits which were earned, or from income which was
received, in a period ending 12 months or more before the date on which the US
Holder becomes the owner of 10% or more of the class of shares in question. If
the US Holder of Ordinary Shares or ADSs is a US partnership, trust or estate,
the refund will be available only to the extent that the income derived by such
partnership, trust or estate is subject to US tax either as the income of a US
resident in its hands or the hands of its partners or beneficiaries, as the case
may be.
 
        The aggregate of the dividend paid to a US Holder who is an individual
or a corporate portfolio holder and the gross tax credit in respect of it will
be treated as dividend income for US federal income tax purposes to the extent
made from current or accumulated earnings and profits of Energy as determined
under US federal income tax principles. Such dividend will not be eligible for
the dividends received deduction allowed to US corporations under Section 245 of
the US Internal Revenue Code. However, the 15% withholding tax will be treated
as a foreign income tax eligible for credit or deduction against such US
Holder's US federal income tax liability at such US Holder's option subject to
applicable limitations. US Holders should consult their tax advisors as to the
method of claiming such foreign tax credit or deduction.
 
        For dividends paid before April 6, 1999, a US Holder who is an
individual or a corporate portfolio holder who receives the L80 dividend in the
above example for US federal income tax purposes would be considered to receive
a dividend of L100 (L80 dividend plus L20 tax credit) and would include the
amount in income. Such US Holder also would be considered to have paid L15 of UK
tax that, subject to the applicable limitations, would be creditable against
such US Holder's US federal income tax liability.
 
        For dividends paid on or after April 6, 1999 (assuming that the current
proposals are enacted and no further changes in law occur) a US Holder who is an
individual or a corporate portfolio holder who receives the L80 dividend in the
above example for US federal income tax purposes should be considered to receive
a dividend of L88.89 (L80 dividend plus the L8.89 tax credit) and would include
that amount in income. Such US Holder also should be considered to have paid
L8.89 of UK tax that, subject to the applicable limitations, would be creditable
against such US Holder's US federal income tax liability.
 
        As a result of recently enacted legislation, a US Holder will be denied
a foreign tax credit with respect to income tax withheld from dividends received
in respect of Ordinary Shares is such US Holder has not had the Ordinary Shares
for a minimum period or to the effect such US Holder is under an obligation to
make certain related payments with respect to substantially similar property.
 
        Energy will use reasonable efforts to effect an "H" Arrangement
("Arrangement") with respect to the payments of dividends to a US Holder of
ADSs. An Arrangement applies where shares are held through an American
depositary receipt system and the operator of such system makes arrangements for
the Tax Treaty Payment to be paid by Energy rather than the UK Inland Revenue at
the same time as the dividend is paid to a US Holder of New Ads if such US
Holder completes the necessary declaration of the US residency and US tax
status. This avoids the need for such a US Holder of ADSs, to the extent such US
Holder is entitled to a Tax Treaty Payment to make a claim to the UK Inland
Revenue for a refund of tax. The following categories of US Holders of ADSs will
be excluded from the Arrangement: (i) any person, whether an individual or a
corporation, who will control 10% or more of the Ordinary Shares or ADSs, (ii)
certain bodies exempt from tax in the US on dividends paid by Energy, (iii)
estates or trusts where any of the beneficiaries are not resident in the US,
(iv) an investment or holding company where 25% of the capital is owned directly
or indirectly by persons who are neither residents of the US nor US nationals,
or (v) a corporation which either alone or together with one or more associated
companies, controls at least 10% of the voting power of Energy. US Holders of
ADSs who are excluded from the Arrangement or who do not satisfy the
requirements stated above must, in order to obtain a refund, file in the manner
and at the time described in Revenue Procedure 80-18, 1980-1 C.B. 623 (as
clarified and amplified by Revenue Procedure 90-61, 1990-2 C.B. 657), Revenue
Procedure 81-58, 1981-2 C.B. 678 and Revenue Procedure 84-60, 1984-2 C.B. 504,
summarized below, a claim for refund identifying the dividends with respect to
which the tax credit was paid.
 
                                       32
<PAGE>   108
 
        A US Holder who does not obtain a refund by completing the declaration
referred to in the preceding paragraph generally is entitled to claim, in
accordance with the refund procedures summarized below, a refund from the UK
Inland Revenue with respect to any dividend paid, to the extent such US Holder
is entitled to a Tax Treaty Payment with respect to such dividend.
 
        The first claim of a US Holder for a refund is made by sending the
appropriate UK form in duplicate to the IRS-Philadelphia Service Center, Foreign
Certification Requests PO Box 16347, Philadelphia, PA 94114-0447. Forms may be
obtained by writing to the US Internal Revenue Service, Assistant Commissioner
International 950 L'Enfant Plaza South, SW, Washington DC 20024, Attention:
Taxpayers Service Division, Room 2223. Because a refund claim is not considered
made until the UK tax authorities receive the appropriate form from the US
International Revenue Service, forms should be sent to the US Internal Revenue
Service well before the end of the applicable limitation period. Any claim for
refund of tax credit by a US Holder after the first claim by such US Holder has
been processed should be filed directly with the UK Financial Intermediaries and
Claims Office (International), FitzRoy House, PO Box 46, Nottingham NG2 1BD,
England.
 
        Under current US Treasury regulations, dividends paid on Ordinary Shares
or ADSs will not be subject to US backup withholding tax. However, if proposed
Treasury regulations are adopted in their current form, on a prospective basis,
dividends paid on Ordinary Shares or ADSs to a US or to a non-US holder in the
US or through US or US-related persons may be subject to a 31% US backup
withholding tax in certain circumstances. In addition, under current US Treasury
regulations, the payment of proceeds of a sale, exchange or redemption of
Ordinary Shares or ADSs to a US Holder or non-US holder in the US or through US
or US-related persons may be subject to US information reporting requirements
and/or backup withholding tax.
 
        US Holders can avoid the imposition of backup withholding tax by
reporting their taxpayer identification number to their broker or paying agent
on US Internal Revenue Service Form W-9. Non-US holders can avoid the imposition
of backup withholding tax by providing a duly completed US Internal Revenue
Service Form W-8 to their broker or paying agent. Any amounts withheld under the
backup withholding rules from a payment to a holder will be allowed as a refund
or a credit against such holder's US federal income tax liability, provided that
the required returns are filed with the US Internal Revenue Service on a timely
basis.
 
GENERAL
 
        Whether holders of Ordinary Shares or ADSs who are resident in countries
other than the US are entitled to refunds of tax credits in respect of dividends
on such shares depends in general upon the provisions of such conventions or
agreements, if any, as may exist between such countries and the UK.
 
UK TAXATION OF CAPITAL GAINS
 
        UK capital gains tax (or, for companies, corporation tax on chargeable
gains) applies only to a UK Holder on the disposal of Ordinary Shares or ADSs,
if held as a capital asset. On such disposal the capital gain or allowance loss
is calculated by reference to the difference between the acquisition cost for UK
tax purposes and the net proceeds realized. Capital gains in each tax year
realized by UK Holders who are individuals are (subject to exemptions and
reliefs) currently taxed at the highest marginal tax rate applicable to the
individual's income. Chargeable gains of UK Holders who are companies are
currently taxed at 33% to be changed to 31% retrospectively from April 1, 1997
under the provisions in the Finance Bill (subject to lower rates for small
companies). UK Holders which are companies can offset ACT (up to a limit)
against their corporation tax liability on all taxable profits, which include
chargeable gains.
 
        A US Holder that is not resident or ordinarily resident for tax purposes
in the UK will not be liable for UK tax on capital gains on the disposal of
Ordinary Shares or ADSs unless the US Holder carries on a trade, profession or
vocation in the UK through a branch or agency and such Ordinary Shares or ADSs
are or have been used by, held by, or acquired for use by or for the purpose of
such trade, profession, vocation, branch or agency.
 
        A US Holder that is liable for both UK tax (ie, capital gains tax or
corporation tax on chargeable gains) and US federal income tax on a gain on the
disposal of Ordinary Shares or ADSs generally will be entitled to offset a
credit for UK tax against its US federal income tax liability in respect of such
gain.
 
UK INHERITANCE TAX (ON ESTATES AND GIFTS)
 
        The Estate and Gift Tax Convention provides that the UK tax to which the
Convention applies is Capital Transfer Tax ("CTT") and that it will also apply
to any identical or substantially similar taxes which are imposed
 
                                       33
<PAGE>   109
 
subsequently. On January 1, 1985 CTT was replaced by a tax known as Inheritance
Tax ("IHT"). It is understood that in practice the US tax authorities and the UK
Inland Revenue apply the Convention on the basis that IHT has replaced CTT as
the tax to which the Convention now applies, although the Convention has not
been amended to that effect.
 
        On the basis of that practice, Ordinary Shares or ADSs held in the US by
an individual who is domiciled for the purposes of the Estate and Gift Tax
Convention in the US and is not for the purposes of the Convention a national of
the UK, will not, be subject to IHT on the individual's death or on a transfer
of the Ordinary Shares or ADSs during the individual's lifetime (although
special rules apply in the case of Ordinary Shares or ADSs held in trust, or as
part of the business property of a permanent establishment in the UK or related
to the fixed base in the UK of a person providing independent personal
services).
 
UK STAMP DUTY AND STAMP DUTY RESERVE TAX
 
        Stamp duty is (subject to exceptions for charities) currently payable at
the rate of 1 1/2% on any instrument transferring Ordinary Shares to the
Custodian of the Depositary, on the value of such Ordinary Shares. In accordance
with the terms of the Deposit Agreement relating to the Ordinary Shares, any tax
or duty payable by the Depositary or the Custodian of the Depositary on future
deposits of Ordinary Shares will be charged by the Depositary to the party to
whom ADSs are delivered against such deposits.
 
        No UK stamp duty will be payable on transfer of an ADS, provided that
the ADS (and any separate instrument of transfer) is executed and retained at
all times outside the UK. A transfer of an ADS in the US thus will not give rise
to UK stamp duty provided the instrument of transfer is not brought into the UK.
A transfer of ADSs in the UK may attract stamp duty at a rate of  1/2% of the
consideration. Any transfer (which will include a transfer from the Depositary
to an ADS holder) of the Ordinary Shares, including ordinary Shares underlying
ADSs, may result in a stamp duty liability at the rate of  1/2% of the
consideration. There is no charge to ad valorem stamp duty on gifts. On a
transfer of Ordinary Shares from a nominee to the beneficial owner (the nominee
having at all times held the Ordinary Shares on behalf of the transferee) under
which no beneficial interest passes and which is neither a sale, nor arises
under or following a contract of sale, nor is in contemplation of sale, a fixed
50p stamp duty will be payable. The amount of ad valorem stamp duty payable is
generally calculated at the applicable rate on the purchase price of the
Ordinary Shares.
 
        Stamp duty reserve tax generally at a rate of  1/2% on the
consideration, is currently payable on any agreement to transfer Ordinary Shares
or any interest therein unless: (i) an instrument transferring the Ordinary
Shares is executed; (ii) stamp duty, generally at a rate of  1/2% is paid; and
(iii) the instrument is stamped on or before the last day of the month following
the month in which the agreement is made, or, where the agreement is
conditional, the last day of the month following the month in which it becomes
unconditional. The duty will, however, be refundable if within six years the
agreement is completed by an instrument which has been duly stamped, generally
at the rate of  1/2%. Stamp duty reserve tax will not be payable on any
agreement to transfer ADSs.

(1)     The results of operations of Eastern, which was acquired by Hanson in
        September 1995, are included above for periods beginning on or after
        October 1, 1995.
(2)     Turnover for the year ended September 30, 1996 is stated net of a
        special discount to electricity customers of L132 million relating to
        the flotation of National Grid Group plc.
(3)     Operating exceptional items in the year ended September 30, 1996 arise
        from the flotation of National Grid Group plc. See Note 7 of Notes to
        the Financial Statements.
(4)     Results for the year ended September 30, 1993 reflect a charge for
        impairment of coal assets of L578 million under the Group's accounting
        policy for the impairment of long-lived assets which, under UK GAAP, is
        reflected in the year such impairment is considered to have been
        incurred.
(5)     Per Ordinary Share data for each of the five years in the period ended
        September 30, 1996 are based on 520.9 million Ordinary Shares (including
        Ordinary Shares represented by ADSs), being the number of Ordinary
        Shares (including Ordinary Shares represented by ADSs) issued in respect
        of the Demerger, and for the six months ended March 31, 1997 are based
        on 518.6 million Ordinary Shares (including Ordinary Shares represented
        by ADSs), being the weighted average number of Ordinary Shares
        (including Ordinary Shares represented by ADSs) in the period, excluding
        Ordinary Shares held by The Energy Group Employee Benefit Trust (which
        has waived its right to dividends on such Ordinary Shares) at the end of
        the period.
(6)     Adjusted earnings per Ordinary Share data are based on the same number
        of Ordinary Shares (including Ordinary Shares represented by ADSs) and
        the profit for the year after excluding the items relating to the
        flotation of the National Grid Group plc, the disposal of the Group's
        interest in First Hydro, other exceptional items and the related
        taxation.
(7)     The principal differences between UK GAAP and US GAAP which affect the
        Group are described in Note 30 of Notes to the Financial Statements.
(8)     The pro forma operating results for the six months ended March 31, 1996
        have been prepared on the same basis as that used by the Group for prior
        periods adjusted to reflect net interest payable and taxation as if the
        Demerger had occurred at the beginning of the period. The pro forma
        adjustment to net interest payable reflects an additional pro forma
        interest charge calculated at 6.2% of the L381 million of additional net
        debt allocated to the Group on the Demerger based on assumptions
        contained in the section captioned "Unaudited Pro Forma Combined
        Financial Information" in the Information Statement, dated January 27,
        1997, issued by Energy in connection with the Demerger (the "Information
        Statement"). The pro forma adjustment to taxation reflects the impact of
        the pro forma adjusted interest charge resulting from the assumed change
        in capital structure of the Group following the Demerger calculated at
        the same effective tax rate before exceptional items as that assumed in
        the pro forma tax charge for the twelve months ended September 30, 1995
        and contained in the section captioned "Unaudited Pro Forma Combined
        Financial Information" in the Information Statement.
(9)     One ADS is equivalent to four Ordinary Shares.

the register of members at the close of business (London time) on June 27, 1997.
 
        For ADS holders, the dividend was converted to US dollars on the UK
dividend payment date using the prevailing exchange rate on that day
(L1.00 = $1.6819). Payment of the July 4, 1997 dividend to ADS holders was made
by the Depositary on July 11, 1997 to holders of record on June 27, 1997.

ITEM 9. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS
 
INTRODUCTION
 
        The Financial Statements of the Group for the three years ended
September 30, 1994, 1995 and 1996 have been prepared on the basis of a fiscal
year ending September 30 consistent with Hanson's fiscal year-end. The Group
adopted a March 31 fiscal year-end commencing with the six months ended March
31, 1997, to conform to the business year most commonly adopted in the UK
electricity industry.
 
        The following discussion is based on the Financial Statements and other
financial information included in this Transition Report. The Financial
Statements for the six months ended March 31, 1997 and for each of the years in
the three year period ended September 30, 1996 have been audited by Ernst &
Young, chartered accountants, independent auditors. The pro forma selected
financial information for the six months ended March 31, 1996 is derived from
unaudited combined financial statements of the Group and has been prepared on
the same basis as that used by the Group for prior periods adjusted to reflect
net interest payable and taxation as if the Demerger had occurred at the
beginning of the period. The selected financial information of the Group for the
years ended September 30, 1992 and 1993 is unaudited, but has been derived from
the audited financial returns submitted to Hanson for consolidation purposes
and, in the opinion of management, has been prepared on a basis consistent with
that for subsequent years. See "Selected Financial Data" in Item 8 of this
Transition Report.
 
        The Financial Statements are prepared in accordance with UK GAAP, which
differ in certain respects from US GAAP. See Note 30 of Notes to the Financial
Statements for a description of the significant differences and a reconciliation
to US GAAP of net income, and invested capital/shareholders' equity for the six
month period ended March 31, 1997 and the three years in the period ended
September 30, 1996. The discussion below should be read in conjunction with the
Financial Statements of the Group and Notes thereto appearing elsewhere in this
Transition Report.
 
        The comparability of the Group's results of operations for the periods
discussed below have been significantly affected by the Demerger and acquisition
of Eastern.
 
THE DEMERGER
 
        Prior to the Demerger, Rollalong (then a wholly-owned subsidiary of
Hanson) acquired, directly or indirectly, 100% of the share capital of each of
Eastern, Consolidated Gold Fields (which indirectly owned Lee Ranch (a single
surface mine)) and Peabody Australia.
 
        The Demerger was effected on February 24, 1997, when Hanson transferred
Rollalong to Energy in consideration for Energy issuing Ordinary Shares
representing all of its then outstanding share capital (other than the
subscriber shares) to holders of Hanson Shares (including Hanson Shares
represented by Hanson ADSs) on a pro rata basis of one Ordinary Share for every
ten Hanson Shares and one ADS for every eight Hanson ADSs. On March 7, 1997,
PUSH, a wholly owned indirect subsidiary of Hanson, transferred to Peabody
Investments (which was and continues to be approximately a 99.4% subsidiary of
Energy, with subsidiaries of Hanson owning the other 0.6% interest), the entire
issued share capital of Peabody, in consideration for $1,637.5 million. The net
effect of the transactions involved in the Demerger was to transfer the energy
business previously conducted by Hanson to the Group and to attribute to the
Group a total of L1,440 million of net indebtedness as of September 30, 1996 on
a pro forma basis.
 
        The Financial Statements for each year in the three year period ended
September 30, 1996 reflect the capital structure in place prior to the Demerger,
which historically was considered appropriate to Hanson, and the capital
position, finance charges and tax liabilities included in such data do not
reflect the capital position, finance charges and tax liabilities which the
Group might have had in respect of any of the periods covered if it had been an
independently financed and managed company during such periods, or which it may
have in respect of any future period.
 
ACQUISITION OF EASTERN
 
        Although Hanson acquired Eastern on September 18, 1995, its results of
operations and cash flows have been included in the Financial Statements
included herein based on an effective acquisition date of September 30, 1995.
Accordingly, the Group's results of operations and cash flows reflect Eastern
from October 1, 1995 and do not include Eastern for prior years while the
balance sheet of Eastern was included in the Group's balance sheet at
 
                                       37
<PAGE>   113
 
September 30, 1995 and the years thereafter. The results and cash flows of
Eastern for the period from September 19, 1995 to September 30, 1995 were not
material.
 
GENERAL BUSINESS TRENDS
 
          Coal
 
        In recent years the coal operations of the Group have generally
experienced declines in the market price of coal, reductions in the average term
of coal supply contracts and reductions in revenues due to the effects of price
reopener provisions, which provide for price increases or decreases to reflect
current market conditions more closely, and expiring coal supply agreements.
These adverse trends have, however, been largely offset by cost reductions and
improved operating efficiencies in the Group's coal operations. The Directors
estimate that price reopener provisions and expiring coal supply contracts have
reduced revenues in excess of $246 million (L150 million) over the six years
since 1990. The Directors believe that the impact on revenues as a result of
contract renegotiations should be less in the coming years than it has been over
the past six years, owing to a decline in the volume of coal represented by
contracts which are due to expire over that period.
 
          Power
 
        Until October 1996, the Group's power operations were only in Great
Britain, where the increase in demand for electricity in recent years has been
modest. However, the Group has managed to increase the profit attributable to
its power operations significantly over the three years to March 31, 1997 by
adding related assets, such as the addition of three power stations leased from
National Power in June 1996 and two power stations leased from PowerGen in July
1996, the two largest generations in the United Kingdom (which increased the
Group's generation capacity by almost 6,000MW), the successful expansion of
electricity and gas sales in markets opened to competition, and the development
of energy trading activities. In addition, the franchise market for electricity
sales is currently scheduled to be fully deregulated over a six month period
commencing from April 1, 1998. Deregulation of the franchise market will allow
Eastern Electricity and other licensed electricity suppliers to compete for
current franchise customers outside their authorized areas. Although Eastern
intends to compete for customers nationally following the introduction of
competition in the franchise market, there can be no assurance that it will be
successful in doing so nor that such competition will not adversely affect
Eastern's operating margins on electricity sales.
 
          Networks
 
        The Group's networks operations have been a predictable source of
operating profits and cashflow and, historically, the growth in units of
electricity distributed has generally matched increases in the gross domestic
product for Great Britain. The networks business is highly regulated and in 1994
and 1995 was the subject of two distribution price reviews by OFFER. The
Directors estimate that the effect of those price reviews will be to reduce
prospective revenues over the five years to March 31, 2000 by some L500 million
compared with expected revenues under the previous distribution price control. A
further distribution price control review is scheduled for 2000. Accordingly,
future increases in profit by the networks operations of the Group will depend
upon unit growth and productivity improvements, which there can be no assurance
the Group will achieve. In addition, any future price reviews by OFFER could
have a material adverse effect on the Group.

RESULTS OF OPERATIONS
 
SIX MONTHS ENDED MARCH 31, 1997 COMPARED WITH UNAUDITED PRO FORMA SIX MONTHS
ENDED MARCH 31, 1996
 
        For the six months ended March 31, 1997, the Group had turnover of L2.5
billion and operating profit (before exceptional items) of L317.0 million
compared to turnover of L1.8 billion and operating profit (before exceptional
items) of L243.0 million for the six months ended March 31, 1996. The 38.9%
increase in turnover and 30.4% increase in operating profit were primarily
attributable to the addition of three power stations leased from National Power
in June 1996 and two power stations leased from PowerGen in July 1996.
 
        After a detailed consideration of the nature of the Group's 33% interest
in the Black Beauty Coal Company joint venture with the Pittsburgh and Midway
Cola Mining Company and Black Beauty Resources, Inc., as of and for the six
months ended March 31, 1997, the Group began to account for the results and
period-end position of that operation on an equity basis rather than on the
basis of proportional consolidation which had historically been applied. The
Group believes this change in treatment better reflects the nature of its
interest in the operation, its revenues and its assets. The principal effect of
the change has been to reduce overall net debt by L62 million. Further details
are contained in Note 13 of Notes to the Financial Statements included herein.
No change in accounting treatment has been applied to any of the Group's other
joint venture operations which are accounted for on a proportional consolidation
basis.

COAL
 
        Coal turnover of L647 million for the six months ended March 31, 1997
decreased 1.4% from L656 million for the six months ended March 31, 1996,
principally as a result of adverse currency movements. Excluding the impact of
currency movements, turnover rose 4%. The positive impact of a 6% growth in
sales volume to 81.4 million tons for the six months ended March 31, 1997 was
partly offset by a decline in spot market coal prices in the Powder River Basin
operations. The mines operated by Peabody Australia had coal sales of 5.0
million tons for the six months ended March 31, 1997, an increase of 19% from
the previous period, resulting from favorable customer demand. Low sulfur coal
sales represented 82% of total coal sales in the six month period ended March
31, 1997 and sales under long term contracts represented 88% of total sales
volume in that period.
 
        Operating profit of L66 million from coal mining operations for the six
months ended March 31, 1997 was the same as for the six months ended March 31,
1996. However, on a US dollar basis, operating profit increased approximately 5%
to $108 million for the six months ended March 31, 1997, primarily as a result
of continued increases in productivity and cost improvements.
 
        Peabody's cost reduction measures and productivity (i.e., tons per man
shift) enhancements continued to have a positive impact on operating profit
which was partly offset by a decline in coal prices. The success of the cost
reduction initiatives improved productivity 13%, with Peabody's US operating
companies averaging 92 tons per employee per manshift for the six-month period
which represents a company record. Peabody Australia's productivity also showed
significant improvement increasing more than 17% from the equivalent period in
the previous year.
 
POWER
 
        Turnover of L1.8 billion from the Group's power operations for the six
months ended March 31, 1997 increased approximately 65% from L1.1 billion for
the six months ended March 31, 1996. The increase was primarily attributable to
the additional output provided by the three power stations leased from National
Power in June 1996 and two power stations leased from PowerGen in July 1996,
which increased Eastern's generating capacity from 495MW at March 31, 1996 to
6,784MW at March 31, 1997. During the six months ended March 31, 1997, sales
from the Group's retail gas business increased approximately 143.7% from L59.0
million for the six months ended March 31, 1996 to L143.8 million for the six
months ended March 31, 1997.
 
        Operating profit of L129 million for the six months ended March 31,
1997, increased approximately 193% from L44 million for the six months ended
March 31, 1996 primarily as a result of the addition of the power stations.
 
NETWORKS
 
        Networks turnover of L247 million for the six months ended March 31,
1997 decreased approximately 1% from L278 million for the six months ended March
31, 1996. As a result of the last regulatory price review in 1995 (effective
April 1, 1996), regulated income decreased L20 million during the six months
ended March 31, 1997, which was partially offset by a L15 million growth in
unregulated income.
 
        Operating profit of L122 million for the Group's networks operations for
the six months ended March 31, 1997 decreased approximately 8% from L133.1
million for the six months ended March 31, 1996. The decrease was primarily
attributable to the effect of the regulatory price review in April 1996, which
lowered revenues without a corresponding decrease in fixed operating costs.
 
EXCEPTIONAL ITEMS
 
        On February 24, 1997, the Group announced the re-opening of Eastern's
voluntary severance scheme in its networks business. The estimated cost of L20
million was provided for at March 31, 1997 and separately identified because of
its size.
 
YEAR ENDED SEPTEMBER 30, 1996 COMPARED WITH YEAR ENDED SEPTEMBER 30, 1995
 
        For the year ended September 30, 1996, the Group had turnover (before
special discount to electricity customers of L132 million relating to the
flotation of national Grid) of L3.8 billion and operating profit (before
exceptional items) of L446 million. the 161% increase in turnover (before
special discount) and 230% increase in operating profit (before exceptional
items) reflect the acquisition of Eastern, the result of which is included in
the Group's Financial Statements from October 1, 1995.
 
                                       40
<PAGE>   116
 
COAL
 
        Coal sales volume of 163 million tons in the year ended September 30,
1996 increased 8% from 151 million tons in the year ended September 30, 1995.
The Directors estimate that Peabody's market share in the United States rose
from 14% in the year ended September 30, 1995 to 15% in the year ended September
30, 1996. The higher volume was attributable to expansion in Peabody's Powder
River Basin operations, including a full year's contribution from the Caballo
and Rawhide mines acquired in November 1994. Peabody Australia had coal sales
volume of 9.7 million tons in the year ended September 30, 1996. Peabody's
overall production reflected the impact of its continued investment aimed at
improving productivity, in particular at Powder River. Low sulfur coal sales
represented 82% of total sales volume in the year ended September 30, 1996, up
from 80% in 1995. Sales under long-term contracts represented 88% of sales
volume in 1996.
 
        Turnover was L1.5 billion in the year ended September 30, 1996, an
increase of 7.1% from L1.4 billion in the year ended September 30, 1995. The
positive impact of higher sales volumes in 1996 was offset by lower pricing of
certain high sulfur coal contracts. Turnover was also adversely affected by
reduced demand at Peabody Western, as customers purchase lower price
hydro-electric generation that was available due to unusually high rain and
show-fall in the western US.
 
        Operating profit of L154 million from coal mining operations for the
year ended September 30, 1996 decreased 4% from L160 million for the year ended
September 30, 1995. The 1996 results were affected by lower customer demand at
Peabody Western, the re-pricing of certain high sulfur coal contracts (which the
Directors estimate accounted for a decrease in profit of L15 million to L20
million), operational difficulties at two Peabody East mines during the first
nine months of the year and a decline in spot prices for coal from the Powder
River Basin.
 
        Offsetting the above conditions was a reduction in costs due to measures
implemented during 1996 as part of continuing efforts to reduce production
costs. These included employee reductions, improvements in working practices
permitted under new union contracts and the effects of investment in more
efficient equipment. The success of Peabody's cost reduction initiatives was
evidenced by an improvement in productivity, as tons per man shift improved 17%
in absolute terms over 1995 and 3% on a weighted average mine by mine basis
taking into account the shift in sources of production. Firming prices in the
higher sulfur spot markets in the last six months of the year also benefited
profits slightly and the re-negotiation of a coal supply agreement resulted in a
one-off receipt of L14 million.
 
        Operating profit in 1996 also includes the benefit of a provision
reduction of L15 million, part of a L42 million reduction in Peabody's provision
relating to a UMWA Combined Fund established under the Health Benefit Act, which
is being released over three years commencing in 1996. This provision reduction
resulted from Peabody's successful appeal of US government beneficiary
assignments and its active participation in the administrative process with
respect to this fund.
 
        Peabody Australia's operating profits of L28 million for the year ended
September 30 1996 increased its contribution from L25 million for the year ended
September 30 1995.
 
POWER
 
        Turnover of L2.2 billion from the Group's power operations for the year
ended September 30, 1996 increased 4% from L2.1 billion for the year ended
September 30, 1995. The increase arose mainly from growth in gas sales and also
from sales related to the addition of three power stations leased from National
Power in June 1996 and two power stations leased from PowerGen in July 1996,
which increased Eastern's generating capacity from 495MW to 6,378MW. There was
also an increase in turnover in the franchise market arising from additional
unit volumes and a tariff increase, which took effect in 1996, although this was
partially offset by a small decrease in turnover from electricity sales
resulting from lower sales prices in the competitive market. Gas sales exceeded
L250 million for the year ended September 30, 1996, an increase of 63% from the
year ended September 30, 1995, as market share continued to grow in the
competitive element of the gas market.
 
        This was achieved by Eastern's increased marketing efforts targeted at
large and medium-sized commercial customers. Growth in Eastern's gas sales was
also assisted by Eastern's taking advantage of falling spot market prices for
gas to lock in sales to customers on favorable terms.
 
        Operating profit of L83 million for the year ended September 30, 1996
increased by 63% from L51 million for the year ended September 30, 1995. This
increase reflects the first time (but part year) contribution from the
coal-fired power stations for the period from July 1996 to September 1996.
 
                                       41
<PAGE>   117
 
NETWORKS
 
        Networks turnover of L482 million for the year ended September 30, 1996
declined by approximately 4% from L501 million for the year ended September 30,
1995. This decline was mainly due to two changes in the distribution price
control formula imposed by the Director General of Electricity Supply ("DGES"),
which were effective from April 1, 1995 and April 1, 1996. The effect of these
changes was partially offset by an above average increase in the volume of units
distributed. This increase in volume arose principally from considerably colder
weather than normal at the end of 1995 and early 1996.
 
        Despite the effects of the revisions to the distribution price control
formula, operating profits (before exceptional items) of L211 million for the
year ended September 30, 1996 increased by 6.6% from L198 million for the year
ended September 30, 1995, due to significant reductions in operating costs in
the distribution business through reductions in manpower.
 
EXCEPTIONAL ITEMS
 
        The principal operating exceptional items in the year ended September
30, 1996 related to the flotation of National Grid and comprised a discount to
electricity customers of L132 million offset by dividends received of L176
million. A further exceptional amount of L25 million represents profit
associated with the disposal of the Group's interest in First Hydro.
 
YEAR ENDED SEPTEMBER 30, 1995 COMPARED WITH YEAR ENDED SEPTEMBER 30, 1994
 
        For the year ended September 30, 1995, the Group had turnover of L1.4
billion and operating profit of L135 million, increases of 16% and 36%,
respectively, over the previous year. As described below, these increases
resulted primarily from Peabody's recovery from the 1993 coal strike which
affected the first quarter of the year ended September 30, 1994.
 
COAL
 
        The major factor contributing to the improved results of Peabody's coal
operation in 1995 was its recovery from the impact of the previous year's coal
strike, which the Directors estimate reduced operating profit by between L70
million and L80 million in the year ended September 30, 1994. Another
contributing factor was the first time contribution from strategic acquisitions
made by Peabody in low sulfur coal mining operations in the Powder River Basin.
 
        Coal sales by volume of 151 million tons in the year ended September 30,
1995 increased 48% from 102 million tons in the year ended September 30, 1994.
The Directors estimate that Peabody's market share rose to 14% in the US in
1995. The acquisition of Rawhide and Caballo mines in Wyoming's Powder River
Basin in the early part of the year ended September 30, 1995 added 30 million
tons to the sales volume while increasing overall coal reserves by more than one
billion tons. Sales of low sulfur coal increased from 75% of total sales in the
year ended September 30, 1994 to 80% in the year ended September 30, 1995 and
approximately 87% of sales volume for 1995 was attributable to long-term
contracts.
 
        Turnover of L1.4 billion in the year ended September 30, 1995 increased
17% from L1.2 billion in the year ended September 30, 1994. Mid weather and
abundant hydro-electric generation in the western US depressed coal prices by 10
to 15% in the calendar year 1995, and the negative impact of the expiration and
re-negotiation of long-term contracts resulted in an average 5% decline in
Peabody's US sales revenues per ton, although this decline was offset by the
increase in sales volumes.
 
        Operating profit of L160 million from coal mining operations in the year
ended September 30, 1995 increased 57% from L102 million in the year ended
September 30,1994, due principally to increased turnover following the end of
the miner's strike. Major investment in more efficient earth moving equipment in
the US and an increase in the proportion of Peabody's US coal production
represented by Powder River coal (from 36% in the year ended September 30, 1994
to 52% in the year ended September 30, 1995) helped increased overall
productivity at Peabody's facilities by 26% during the year ended September 30,
1996. Productivity per man shift improved at all US operations other than in
West Virginia, which experienced operating and geological difficulties at
several of its mining facilities. Peabody Australia's operations contributed an
operating profit of L25 million in the year ended September 30, 1995 compared
with L27 million in the previous year.
 
                                       42
<PAGE>   118
 
        Operating difficulties as Peabody East's Tygart River, Colony Bay,
Harris and Camp 11 mines had an adverse impact on 1995 operating profit, as
profits at these locations were approximately L30 million lower than anticipated
levels. Profits were also adversely affected by the lower steam coal prices in
the western US and the expiration on re-pricing of long-term contracts.
 
        Peabody Australia acquired an additional 10% interest in the Bengalla
Mine Development in New South Wales during the year, bringing its interest in
the venture to 35%. Bengalla is expected to commence production in 1999.
 
POWER
 
        Turnover of L2.1 billion from the Group's power operations in the year
ended September 30, 1995 an increase of 17.5% from L1.8 billion in the year
ended September 30, 1994 arose principally from an increase of approximately 10%
in net additional sales volume from the year ended September 30, 1994 the
enlarged national competitive market which opened up (for customers with annual
maximum demands of 100kW or more) on April 1, 1994. Gas sales of L158 million in
the year ended September 30, 1995 increased 229% from L48 million from the year
ended September 30, 1994 as market shares increased due to focused marketing
efforts towards new customers, including trade associations and multiple retail
outlets. The full consolidation of the Peterborough power station, following the
acquisition of the remaining 50% share from Hawker Siddeley in September 1994,
also contributed L75 million to the increase in turnover.
 
        Operating profit of L51 million for the year ended September 30, 1995,
increased by 82% from L28 million for the year ended September 30, 1994. This
reflected the effects of the review by the DGES of the supply price control
(covering the reduced franchise market) and successful entry into the
competitive electricity sales market, both with effect from April 1, 1994, and
the contribution from the additional 50% interest in Peterborough power station
acquired in September 1994.
 
NETWORKS
 
        Turnover of L501 million from the Group's networks operations for the
year ended September 30, 1995 decreased by 3% from L514 million in the year
ended September 30, 1994. This decrease principally reflected the effect of the
first review of distribution charges applicable from April 1, 1995, which
reduced turnover in the distribution business by approximately 2% compared with
the previous year. The remaining L3 million decline in turnover resulted from a
lower volume of charges for new connections and ancillary networks.
 
        Operating profit of L198 million for the year ended September 30, 1995
decreased by L11 million from L209 million for the year ended September 30,
1994. The principal reason for this decrease was the reduction in the
distribution charges from April 1, 1995.
 
LIQUIDITY AND CAPITAL RESOURCES
 
        Prior to the Demerger, the Group financed its operations and capital and
other expenditures from a combination of cash generated from operations,
external borrowings and loans and invested capital provided by Hanson or its US
affiliates. Since the Demerger, the Group has had to meet all of its cash
requirements through internally generated funds and external borrowings. The
Group's ability to generate cash from operations depends upon numerous business
factors, some of which are outside the control of the Group, including changes
in economic and climatic conditions and taxation regimes in force in each
country of operation.
 
        Net cash generated by operating activities was L346 million for the six
months ended March 31, 1997. Net cash generated by operating activities was L12
million for the year ended September 30, 1996 compared with L402 million for the
year ended September 30, 1995. The decrease in 1996 resulted principally from
payments made under the agreements to lease power stations from National Power
amounting to L342 million, an increase in working capital requirements (due
mainly to the purchase of fuel stocks for the coal-fired power stations) and an
increase of L72 million of UK advance corporation tax ("ACT") recoverable. Net
cash provided by operating activities for the year ended September 30, 1995 was
higher by L259 million than the previous year, largely because of improvements
in working capital as well as an operating profit increase of L36 million.
 
        Net cash used by investing activities was L176 million for the six
months ended March 31, 1997. Net cash used by investing activities was L2,605
million for the year ended September 30, 1996 compared with net cash used of L73
million for the year ended September 30, 1995. The increase principally relates
to the payment for the acquisition of Eastern of L2,495 million. In addition,
there were further outflows in 1996 in respect of capital
 
                                       43
<PAGE>   119
 
investments made in plant and equipment in the previous year and in the
distribution system of the networks business and capital installments of L93
million paid in respect of the new 340MW gas-fired power station at King's Lynn.
Net cash used in investing activities was L73 million in the year ended
September 30, 1995, compared with L57 million for the year ended September 30,
1994. The principal reason for this increase in net cash used in investing
activities related to the acquisition by Peabody of the Caballo and Rawhide coal
mines in the United States, which was partly offset by cash deposits of L264
million acquired with Eastern.
 
        The Group made capital expenditures of L133 million in the six months
ended March 31, 1997 and L133 million, L140 million and L374 million in the
years ended September 30, 1994, 1995 and 1996, respectively. In addition,
Eastern made capital expenditures of L113 million in the year ended September
30, 1994 and L212 million in the year ended September 30, 1995. As of March 31,
1997, the Group had capital commitments totalling L146 million, including
commitments relating to the completion of the King's Lynn power station. The
Group anticipates funding these capital expenditures with its internally
generated cash and borrowings under its available bank facilities.
 
        Net cash from financing activities was L938 million for the six months
ended March 31, 1997. Net cash from financing activities was L2,418 million in
the year ended September 30, 1996 compared with L77 million used for the year
ended September 1995, principally representing the contribution to invested
capital by Hanson for the acquisition of Eastern. Net cash used in financing
activities of L34 million in 1994 principally relates to repayment of invested
capital to Hanson.
 
        Profit of L150 million was retained and added to shareholders' funds for
the six months ended March 31, 1997, after allowing for the L29 million cost of
the dividend. Overall shareholders' funds have decreased L340 million since
October 1, 1996, with retained earnings being more than offset by the additional
net debt of L423 million attributed to the Group pursuant to the Demerger,
together with adverse currency differences on foreign net investments of L52
million.
 
FINANCING ARRANGEMENTS
 
        Prior to the Demerger, the Group entered into a credit facility (the
"Credit Facility") with various participating banks for the provision of credit
facilities to the Group and its subsidiaries. As of March 31, 1997, L500 million
of borrowings were outstanding under the Credit Facility.
 
        The Credit Facility consists of a five-year syndicated multi-currency
unsecured revolving credit facility in an amount up to L1 billion including a US
dollar swingline facility (with an acceptance credit option) of the US dollar
equivalent of L300 million. The proceeds of the Credit Facility may be used to
provide working capital to the Group for general corporate purposes of the
Group, including the repayment of debt to Hanson or Hanson subsidiaries.
 
        The interest rates under the revolving credit facility are based upon
either the London Interbank Offered Rate plus Mandatory Liquid Asset Costs in
the case of sterling advances, or the Eligible Bill Discount Rate, plus 0.1875%
per annum, in the case of sterling banker's acceptances. The interest rate under
the swingline facility is the higher of (a) the aggregate of the US Federal
Funds Rate and 0.5% per annum and (b) the prime commercial lending rate from
time to time publicly announced by the agent bank.
 
        The Credit Facility requires the Group to satisfy certain financial
performance criteria. In particular, "operating profit" (as defined) must be a
minimum of 2.25 times the level of net interest expense for each semi-annual
period. The Credit Facility also contains covenants and provisions that
restrict, among other things, the ability of the Group and its material
subsidiaries to: (i) create any security interest on any of its property or
assets, or (ii) dispose of all or substantially all of the assets of Peabody or
Eastern other than to another member of the Group.
 
        In addition to the Credit Facility described above, the Group has
available uncommitted bank facilities of approximately L467 million. As of March
31, 1997, L63 million of borrowings were outstanding under these facilities.
 
        As of March 31, 1997, Eastern Electricity had issued long-term, fixed
rate bonds in the aggregate outstanding principal amount of L727 million and on
April 14, 1997, a further bond issue of L200 million was made at a fixed rate of
8.75% per annum. The Group may from time to time issue additional bonds.
 
        During the six months ended March 31, 1997, certain subsidiaries of
Energy entered into an agreement with commercial banks under which certain
future intra-group rental payments receivable from the leased power station
facilities at Drakelow C, High Marnham, Ironbridge, Rugeley B and West Burton
for a five year period were assigned
 
                                       44
<PAGE>   120
 
in return for a capital sum of L1,097 million. Such capital sum was drawn down
on October 28, 1996 and L408 million was used to cash collateralize existing
future obligations to certain banks in respect of the funding of the operating
leases of power stations leased from National Power. The remaining funds are
held within the Group. The payment of the assigned rentals or, in certain
circumstances, their capital value on resale by the banks, is subject to
guarantees and indemnities provided by Energy subsidiaries.
 
        As of March 31, 1997, the Group's gearing was 71%, defined as net debt
divided by net equity. This compares with pro forma gearing as of September 30,
1996 of 80%. The decrease principally reflects the positive cash generation from
the operating businesses and profits retained within the Group.
 
CERTAIN ENVIRONMENTAL MATTERS
 
        As discussed under "Regulatory Matters" in Item 1 of this Transition
Report, the Group's operations are subject to extensive and changing regulation
in the United States, United Kingdom and Australia regarding environmental
matters. As of March 31, 1997, the Group had a provision of L280 million for
reclamation and environmental obligations. The Group's expenditures relating to
environmental matters were approximately L13 million in the six months ended
March 31, 1997 and L38 million, L43 million and L43 million in the years ended
September 30, 1994, 1995 and 1996, respectively.
 
        Certain US subsidiaries of Consolidated Gold Fields, which are members
of the Group, are or may become parties to environmental proceedings which have
been commenced or threatened in the United States in relation to certain sites
previously owned or operated those subsidiaries or companies associated with
them. This includes sites formerly owned or operated by Consolidated Gold Fields
as well as dormant sites that the Group currently owns. The US Environmental
Protection Agency ("EPA") has placed some of these sites on the National
Priorities List promulgated pursuant to the Comprehensive Environmental
Response, Compensation and Liability Act of 1980, as amended ("CERCLA" or
"Superfund"), and some of these sites are on similar state priority lists. There
are a number of further sites in the United States which were previously owned,
operated or used by such companies which could give rise to environmental
proceedings in which members of the Group could incur liabilities. Where such
sites have been identified, the Directors have commissioned a review of publicly
available information by independent environmental consultants in order to
assess the total amount of the liability per site and also the proportion of
those liabilities which the members of the Group are likely to bear. The
available information on which to base this review is very limited, especially
in relation to sites which are no longer owned, operated or used by members of
the Group. On the basis of that review the Directors have made a provision
against the above environmental liabilities relating to Consolidated Gold Fields
in the total sum of $73.6 million as of March 31, 1997 (which is included in the
overall provision of L280 million), but significant uncertainty exists as to
whether these claims will be pursued against the Group in all cases, and where
they are pursued, the amount of the eventual costs and liabilities, which could
be greater or less than the Group's provision. See Note 21 of Notes to the
Financial Statements included herein.
 
While the Group believes that it has identified costs likely to be incurred for
environmental matters, and that those costs are not likely to have a material
adverse effect upon the Group's business or financial position, there can be no
assurance that the Group's total costs and liabilities for environmental matters
will not increase in the future. The magnitude of such additional liabilities
and the costs of complying with environmental laws and containing or remediating
contamination cannot be predicted with certainty due to the lack of specific
information available with respect to many sites, the potential for new or
changed laws and regulations and for the development of new remediation
technologies and the uncertainty regarding the timing of work with respect to
particular sites. As a result, there can be no assurance that material
liabilities or costs related to environmental matters will not be incurred in
the future or that Energy's liquidity will not be adversely impacted by such
environmental liabilities or costs. See "Business - Regulatory Matters".
 
PENSION SURPLUS CONTINGENCY
 
        In February 1997 final determinations were made against National Grid
and its group trustees by the Pensions Ombudsman on complaints by two pensioners
in National Grid's section of the Electricity Supply Pension Scheme ("ESPS")
relating to the use of the surplus arising under the actual valuation of the
National Grid section as of March 31, 1992 to meet certain additional costs
arising from the payment of pensions on early retirement pursuant to
reorganization or redundancy and certain additional contributions. These
determinations were set aside by the High Court on June 10, 1997 and the
arrangements made by National Grid and its trustees in dealing with its
section's surplus were confirmed, although leave to appeal to the Court of
Appeal has been granted to the two pensioners. If a similar complaint were to be
made against Eastern in relation to its use of actuarial surplus in its section
of the ESPS, it would resist it, ultimately through the courts. However, if a
determination were finally to be made against it and
 
                                       45
<PAGE>   121
 
upheld by the courts, Eastern could have a potential liability to repay to its
section of the ESPS an amount estimated by the Directors to be up to L75 million
(exclusive of any applicable interest charges).
 
WINDFALL TAX
 
        The UK Finance (No 2) Act 1997 introduced a windfall tax on certain
privatized undertakings. This one-time tax applies to companies privatized by
flotation and regulated by statute and therefore includes Eastern. The tax is
charged at a rate of 23% of the difference between company value, calculated by
reference to profits over a period of up to four years following privatization,
and the value placed on the company at the time of flotation. The charge for
Eastern is estimated to be approximately L112 million. The tax is payable in two
equal installments on or before December 1, 1997 and December 1, 1998.
 
FINANCE ACT 1997
 
        The UK Finance Act 1997 was enacted in March 1997. One of the provisions
of this Act reduces the capital allowances available in relation to certain
types of capital assets, including certain capital assets of the types acquired
after November 1996 by Eastern in connection with its networks business. The
Directors estimate that Eastern's annual tax charge could be increased by
approximately L10 million as a result of this legislation.
 
FOREIGN CURRENCY MATTERS
 
        The functional currency of each of the Group's non-UK operations
(principally the operations of Peabody in the US and of Peabody Australia in
Australia) is the local currency. The impact of currency translation in
combining the results of operations and financial position of such operations
has not been material to the consolidated (combined) financial position of the
Group. Additionally, the Group generates revenue from exports (see Note 4 of
Notes to the Financial Statements included herein) and revenue from operations
conducted outside the UK which may be denominated in currencies other than
sterling, US dollars or Australian dollars.
 
EFFECT OF INFLATION
 
        Because of the relatively low level of inflation experienced in the
United Kingdom and the United States, inflation did not have a material impact
on the Group's results of operations for the six months ended March 31, 1997 or
the years ended September 30, 1994, 1995 or 1996.

ITEM 11. COMPENSATION OF DIRECTORS AND OFFICERS
 
        For the six months ended March 31, 1997, the aggregate compensation paid
or accrued by the Group to or for all Directors and executive officers at March
31, 1997 as a group (10 persons) for services in all capacities was
approximately L1.1 million.
 
        The remuneration of Energy's senior executives consists of:
 
        Base salary - This is set by reference to individual responsibilities,
performance and external market data. In addition certain benefits in kind are
provided, principally a fully expensed motor car and medical and life insurance.
 
        Annual bonus - An annual performance-related cash bonus can be earned,
subject to the achievement of pre-determined annual profit targets. The maximum
amount of annual bonus is 75% of base salary for Irl Engelhardt and 50% of base
salary for Derek Bonham, Eric Anstee and John Devaney. Each of the last three
may elect, at the commencement of the financial year concerned, to take all, or
part, of any bonus to which they become entitled in Ordinary Shares, entitling
them to receive, three years after the bonus would otherwise have been paid,
shares equal to 133.4% of the cash value of that part of the bonus in respect of
which they have made such an election, subject to their remaining in employment
with the Group for that further three year period. A cash bonus was earned by
senior executives (including the executive Directors) for achieving profit
targets for the six month period to March 31, 1997.
 
        The Long Term Incentive Plan ("LTIP") - Certain executives (including
the executive Directors) are granted performance-related awards of Ordinary
Shares up to a maximum market value of 75% of base salary each year. The first
awards, granted in February 1997, require the achievement of a total shareholder
return, normally calculated over three years, which is greater than the return
achieved by at least half of the constituents of the FTSE 100 index for the
awards to vest. 30% of the awards will vest if energy achieves a total
shareholder return greater than that achieved by 50% of the comparator group,
with all of the awards vesting if the total shareholder return is greater than
that achieved by 80% of the comparator group over the same three year period.
Awards will vest proportionately if the shareholder return falls between these
two points.
 
        In recognition of the fact that the first awards under the LTIP will
not, except in special circumstances, vest until after the expiration of the
applicable three year performance period, the Remuneration Committee established
a special additional bonus scheme for certain executives (including the
executive Directors). Under this arrangement, if earnings of Energy increase by
RPI plus 6% or more in each of the years ending on March 31, 1998 and 1999,
participants will be entitled to receive an award of Ordinary Shares, valued at
the beginning of the respective year, equal to 25% of base salary for that year.
 
        The Energy Group Executive Share Option Scheme ("Executive
Scheme") - The maximum value of Ordinary Shares over which options can be
outstanding in favor of any participant under Energy's UK Inland Revenue
approved Executive Share Option Scheme is L30,000. Under Energy's current
policy, participants in the LTIP may not also be granted executive share
options. Also, under the rules of this scheme, Energy's Directors are not
eligible to be granted executive share options.
 
        Savings-related share schemes - Energy operates savings-related share
schemes providing a long-term savings and investment opportunity for all
qualifying employees (including the executive Directors) in the UK and US.
 
        The Energy Group Sharesave Scheme ("Sharesave Scheme"). Under the UK
Inland Revenue approved Sharesave Scheme, options over Ordinary Shares may be
granted at a price equivalent to not less than 80% of the market value of the
shares at the time when participation in the scheme is offered, and are normally
exercisable three or five years after the date of grant.
 
        Peabody Savings Plans ("Peabody Plans"). In the US employees may
participate in retirement savings plans which provide for the purchase of
Ordinary Shares or ADSs in Energy. Employees contribute a percentage of basic
pay in respect of which their employing companies make limited matching
contributions. The value of the matching contributions is restricted under US
regulations.
 
        Pensions. Energy operates or participates in a number of defined benefit
pension schemes for employees (including executive Directors) in the UK, the US
and Australia. Mr Bonham's salary from Energy is not pensionable. Messrs Anstee
and Devaney are members within the Eastern group of the Electricity Supply
Pension Scheme and have been granted special terms which provide for pensions
equal to 1/30 of pensionable salary for each year of
 
                                       48
<PAGE>   124
 
pensionable service. Mr Engelhardt is a member of the contributory Peabody
Salaried Plan, under which benefits relate to the number of years of service and
compensation limits under US federal tax laws. With the exception of Mr Bonham,
each of the executive Directors is also entitled to unfunded retirement benefit
scheme arrangements to provide for full pensions, depending on years of service.
The total unfunded retirement benefit scheme arrangements which are provided for
amounted to L5 million at March 31, 1997 of which L3 million related to Messrs
Anstee, Devaney and Engelhardt.

Energy from the dates of their respective appointments as Directors to March 31,

mid-merit                    refers to generating plant that normally operates
                             daily, typically between 0700 hours and 2300 hours.
                             This plant is usually shut down during the night

overburden ratios            the number of cubic yards of earth and rock
                             overlying the coal that must be removed to uncover
                             one ton of coal
 
probable reserves            in relation to coal, means reserves for which there
                             is a moderate degree of geological assurance. Coal
                             tonnages are computed by projection of data from
                             available scam measurements for a distance beyond
                             coal classed as measured or proven. The assurance,
                             although lower than for proven coal, is high enough
                             to assume continuity between points of measurement.
                             The maximum acceptable distance for projection of
                             indicated probable tonnage is 1/2 to 3/4 mile from
                             points of observation. Further exploration is
                             necessary to place these reserves in a proven
                             category
 
proven reserves              in relation to coal, means reserves for which there
                             is the highest degree of geological assurance. The
                             sites for measurement are so closely spaced and the
                             geological character so well defined that the
                             thickness, real extent, size, shape and depth of
                             coal are well established. The maximum acceptable
                             distance for projections from seam data points
                             varies with the geological nature of the coal seam
                             being studied, but generally, a radius of 1/4 mile
                             is recognized as the standard. Proven reserves may
                             also be referred to as measured
 
recoverable reserves         the amount of coal that can be recovered from the
                             reserve base taking into account all losses

                             existing methods and under current law. In the US
                             the average recovery factor for underground mines
                             ranges from 45 to 60% and about 90% from surface
                             mines

                             during coal combustion. These devices combine the
                             sulfur in gaseous emissions with other chemicals to
                             form inert compounds, such as gypsum, which must
                             then be removed for disposal. Although effective in
                             substantially reducing sulfur from combustion
                             gases, scrubbers require about 3 to 5% of a power
                             plant's electrical output and thousands of gallons

                         REPORT OF INDEPENDENT AUDITORS
 
To:  The Board of Directors
     The Energy Group PLC
 
     We have audited the consolidated balance sheets of The Energy Group PLC as
at 31 March 1997 and 30 September 1996, and the related consolidated profit and
loss accounts and statements of total recognised gains and losses, cash flows
and changes in invested capital/shareholders' equity for the six months ended 31
March 1997 and each of the three years in the period ended 30 September 1996.
These financial statements are the responsibility of the Company's management.
Our responsibility is to form an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with United Kingdom auditing
standards which do not differ in any significant respect from United States
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 of our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of The Energy
Group PLC at 31 March 1997 and 30 September 1996, and the consolidated results
of its operations and its consolidated cash flows for the six months ended 31
March 1997 and each of the three years in the period ended 30 September 1996 in
conformity with accounting principles generally accepted in the United Kingdom
which differ in certain respects from those generally accepted in the United
States (see Note 30 of Notes to the Financial Statements).

No goodwill arose on the acquisition of the Group's Interest in Teplarny Brno.
 
The cumulative amount of goodwill resulting from acquisitions prior to 31 March
1997, net of goodwill attributable to subsidiary undertakings or businesses
disposed of prior to 31 March 1997, amounted to L1,147 million derived by
calculating the amount of historical goodwill in the currency of acquisition at
period end rates of exchange. This has been set off against merger reserve and
the net amount reported as other reserves.
 
Included in the consolidated reserves as at 31 March 1997 was L1 million in
respect of associated undertakings, all of which arose in the period ended 31
March 1997.
 
There are no significant statutory or contractual restrictions on the
distribution of current profits of subsidiary or associated undertakings:
undistributed profits of prior years are, in the main, permanently employed in
the businesses of these companies. The undistributed profits of Group companies
overseas may be liable to overseas taxes and/or UK taxation (after allowing for
double taxation relief) if they were to be distributed as dividends.

                       NOTES TO THE FINANCIAL STATEMENTS
1.  THE COMPANY AND ITS CAPITALISATION
 
The Company was incorporated as a private limited company on 1 October 1996 as
The Energy Group Limited, with an authorised share capital of L50,000 divided
into 5,000,000 ordinary shares of 1p each, of which two ordinary shares were
issued to the subscribers fully paid. On 4 December 1996, 4,999,998 of the
authorised but unissued ordinary shares of 1p each were converted into 4,999,998
redeemable preference shares of 1p each (the "Preference Shares") and were
issued on that date at par. On 6 December 1996, the Company was re-registered as
a public limited company under the name The Energy Group PLC. The Preference
Shares were redeemed at par prior to the Demerger using funds contributed to the
Company by Hanson and such shares were re-converted into ordinary shares of 1p
each. On 22 January 1997, the Company's authorised share capital was increased
to L100,000,000 by the creation of 9,995,000,000 ordinary shares of 1p each.
Upon admission of the Company's ordinary shares to the Official List of the
London Stock Exchange becoming effective ("Admission"), every ten authorised and
issued ordinary shares of 1p each were consolidated into one ordinary share of
10p. 520,857,817 ordinary shares of 10p each were in issue following this
consolidation.
 
THE DEMERGER
 
At the date of the Demerger, Rollalong Limited ("Rollalong"), a wholly-owned
subsidiary of Hanson, pursuant to an agreement dated 27 January 1997 (the
"Demerger Agreement"), owned or had contracted to acquire, all of the
energy-related businesses of Hanson, as described below.
 
At various dates between 30 September 1996 and 27 January 1997, various of the
energy-related businesses of Hanson were reorganised under the ownership of
Rollalong, Peabody Holding Company, Inc. and its subsidiaries ("Peabody
Holding") was transferred to a subsidiary of Rollalong on 7 March 1997. On 24
February 1997, Hanson transferred to the Company the entire issued share capital
of Rollalong. In consideration for which the Company issued ordinary shares,
credited as fully paid, to Hanson shareholders pro rata to their shareholdings
in Hanson, in satisfaction of a dividend in specie declared by Hanson. The
transactions provided for under the Demerger Agreement, including the agreement
for the transfer of Peabody Holding, are together referred to as the "Demerger
Transactions".
 
THE GROUP
 
Following completion of the Demerger Transactions, the Company became the
holding company for a group of companies and businesses (together, the "Group")
comprising:

THE ENERGY GROUP PLC
- --------------------------------------------------------------------------------
 
2.  BASIS OF PREPARATION
The financial statements have been prepared to show the performance of the Group
for the three years and six months in the period ended 31 March 1997 as if it
had been in existence from 1 October 1993 as described below. Peabody and the
infrastructure companies were wholly-owned by Hanson throughout that period
until they became part of the Group upon completion of the respective Demerger
Transactions. Eastern was acquired by Hanson on 18 September 1995.
 
(i)  The financial statements have been prepared using merger accounting
     principles as if the companies and businesses comprising the Group had been
     part of the Group for all periods presented, or, in the case of those
     acquired or disposed of (other than pursuant to the Demerger Transactions)
     during this period, from or up to the date control passed, as appropriate.
 
     Some individual elements of the reorganisation under Rollalong and of the
     Demerger Transactions were for cash consideration. Such individual elements
     do not satisfy all of the conditions for merger accounting to be permitted
     in accordance with UK Financial Reporting Standard 6 and Schedule 4A to the
     Companies Act 1985 (the "Companies Act"), which would require such
     transfers to be accounted for using acquisition accounting principles.
 
     The Directors took account of the continuity of ownership under Hanson of
     all of its energy-related businesses that formed the Group following
     completion of the Demerger Transactions and considered that the Demerger
     Transactions, taken as a whole, required the adoption of merger accounting
     principles in order to show a true and fair view in accordance with section
     226(5) of the Companies Act.
 
     The adoption of acquisition accounting principles for some individual
     elements of the reorganisation under Rollalong and of the Demerger
     Transactions would have required: the restatement at fair value of certain
     assets and liabilities transferred; the recognition of goodwill which, in
     some cases, would not be representative of that arising had the transfers
     been conducted at arm's length; and the inclusion of the results of certain
     businesses only from the various arbitrary dates chosen for the transfers.
     As a result of the foregoing, in the opinion of the Directors, financial
     statements using different bases of accounting would not give a true and
     fair view. No qualification has been given of the effects of this departure
     because to do so would be misleading.
 
(ii) Although Eastern was acquired by Hanson on 18 September 1995, its results
     and cash flows have been included in the financial statements based on an
     effective acquisition date of 30 September 1995. The results and cash flows
     for the period 19 to 30 September 1995 are not material.
 
(iii)Transactions and balances owing between companies and businesses forming
     part of the Group have been eliminated.
 
(iv) Interest income and expense prior to the Demerger are based on amounts
     recorded in the historical financial returns submitted to Hanson in respect
     of the companies and businesses forming part of the Group. No adjustments
     have been made to reflect the capital structure of the Group as it is
     following the Demerger and, as such, the historical level of interest
     income and expense may not be representative of such amounts following the
     Demerger.
 
(v)  Taxation charges and liabilities prior to the Demerger are based on amounts
     recorded in the historical financial returns submitted to Hanson in respect
     of the companies and businesses forming part of the Group, except that
     adjustments have been made, where appropriate, to provide for deferred tax
     liabilities consequent upon the Group being on a stand-alone basis
     following Demerger. Prior to the Demerger and in previous accounting
     periods, there were various tax-sharing arrangements between Hanson, those
     subsidiaries that form part of the Group and other Hanson subsidiaries.
     These arrangements have had the effect that tax charges shown in the
     financial statements may not be representative of tax charges that will be
     incurred following the Demerger.
 
The preparation of the financial statements requires management to make
estimates and assumptions that affect the amounts reported. Actual results could
differ from estimates.
 
                                       F-7
<PAGE>   141
 
The financial statements have been prepared in accordance with applicable UK
Accounting Standards. The principal accounting policies, which have been applied
consistently for all periods, are set out below.
 
Accounting convention
The financial statements have been prepared in accordance with the historical
cost convention.
 
Accounting for acquisitions
Other than in respect of the Demerger Transactions, the results of acquired
companies and businesses are dealt with in the financial statements from the
date of acquisition. On the acquisition of a company or business, fair values
reflecting conditions at the date of acquisition are attributed to the
identifiable tangible assets and liabilities acquired. Where the consideration
paid exceeds the fair value of the net tangible assets acquired, the difference
is treated as goodwill and is set off against reserves in the acquisition
period.
 
Associated undertakings
Investments which are not subsidiary undertakings and over which the Group
exercises significant influence (other than those which are unincorporated joint
ventures) have been accounted for as associated companies using the equity
method of accounting. Where the Group has an interest in an unincorporated joint
venture or a partnership, such interest has been accounted for as follows:
 
(i)  where all of the ventures share in common the benefits and risks of the
     entire venture, the Group's interest is accounted for using the equity
     method of accounting.
 
(ii) where each venturer has its own separate interest in the benefits and
     risks, the Group's interest is accounted for using proportional
     consolidation on a line-by-line basis.
 
Turnover
 
Coal sales revenue is recognized at the time of shipment. Electricity and gas
sales include an estimated accrual for the value of electricity and gas consumed
by customers between the date of their last meter reading and the period end.
Turnover is stated exclusive of UK value added tax, but inclusive of related US
coal production duties and UK fossil fuel levy.
 
Tangible fixed assets
(a) Capitalisation
 
Tangible fixed assets are stated at cost or valuation less accumulated
depreciation.
 
Interest costs relating to the construction or development of production
facilities are capitalised during the pre-production period. Interest costs
incurred after production has commenced are expensed.
 
Costs incurred to increase the productive capacity of a coal mine or gas field
are capitalised. Costs incurred to maintain the productive capacity of a coal
mine or gas field are expensed.
 
(b) Depreciation and depletion
Buildings and improvements at coal mines are depreciated over the expected
productive life of the mine from the date that full production commences.
 
Depletion of coal and gas reserves is charged on a unit-of-production basis,
based on an assessment of available and proven reserves respectively.
 
Freehold land is not depreciated.

THE ENERGY GROUP PLC
- --------------------------------------------------------------------------------
3.  PRINCIPAL ACCOUNTING POLICIES (CONTINUED)
 
Depreciation of assets other than freehold land, coal and gas reserves and
buildings and improvements at coal mines is charged as follows:
 
<TABLE>
<S>                                              <C>
Electricity generating station assets            30 years
Electricity distribution system assets           40 years at a rate of 3 per cent per annum for first
                                                 20 years and 2 per cent per annum for remaining 20
                                                 years
Freehold buildings                               up to 60 years
Leasehold buildings                              shorter of 60 years and remaining period of lease
Telecommunications network assets                10 to 40 years
Plant, equipment and motor vehicles              2 to 49 years
</TABLE>
 
(c) Assets held under leases
Assets held under finance leases are included within fixed assets at the
capitalized value of future minimum lease payments and are depreciated over the
shorter of their lease period and their useful life. The capital element of the
future payments is treated as a liability and the interest element is charged to
the profit and loss account so as to reflect a constant annual rate of interest
on the remaining balance of the outstanding obligation.
 
Rentals paid on operating leases are charged to the profit and loss account on a
straight line basis over the shorter of the lease period and the useful life of
the leased asset.
 
(d) Impairment
At each financial year end, an assessment is made of the recoverability of the
balance sheet carrying values of coal and gas assets. This assessment is made
individually at the lowest operational level at which income and cash flows are
monitored as a separate unit. A reduction in carrying value is triggered when
the current book value of such a unit of assets exceeds the undiscounted future
cash flows. Where shortfalls in cash flows compared with carrying values arise,
the assets are written down to fair value, determined usually by discounted
future cash flows generated from the assets.
 
(e) Reclamation, restoration and abandonment costs
Provision is made for surface reclamation and restoration costs in respect of
coal mines and for abandonment costs in respect of gas fields in accordance with
local conditions and requirements on the basis of costs estimated at the balance
sheet date. The costs are charged to accounting periods on a unit-of-production
basis for gas assets and over the life of the mine for coal.
 
(f) Environmental costs and obligations
Costs incurred in respect of environmental protection are capitalized if they
provide future economic benefits for the related production facility.
Liabilities for environmental clean-up costs are recognised when clean-ups are
probably and the associated costs can be estimated reasonably.
 
(g) Customers' contributions
Customer contributions to electricity distribution system assets are credited to
the profit and loss account over a 40-year period at a rate of 3 per cent per
annum for the first 20 years followed by 2 per cent per annum for the following
20 years. The unamortized amount of these contributions is deducted form
tangible fixed assets.
 
(h) Disposals of fixed assets
HM Government is entitled to a proportion of any gain realised by Eastern on
certain property disposals made up to 31 March 2000. A provision for drawback in
respect of such disposals is made to the extent that it is probable that a
liability would crystalize. Such a liability would crystalize when an actual or
deemed disposal occurs.

3.  PRINCIPAL ACCOUNTING POLICIES (CONTINUED)
Stocks
Stocks are stated at the lower of cost and net realisable value. Cost includes
labour, supplies, equipment and an appropriate proportion of operating and
overhead costs.
 
Investments
Fixed asset investments are stated at cost or Directors' valuation less
provisions for permanent diminutions in value. Current asset investments are
stated at the lower of cost and net realisable value. Investment income is
included in the financial statements of the period to which it relates.
 
Foreign currencies
Transactions in foreign currencies are recorded at the exchange rates ruling at
the date of the transactions. Monetary assets and liabilities denominated in
foreign currencies are translated at the rates of exchange ruling at the balance
sheet date. All differences on translation are taken to the profit and loss
account.
 
Average rates of exchange ruling during the period are used to translate the
profit and loss accounts of overseas subsidiary and associated undertakings. The
balance sheets of overseas subsidiary undertakings are translated at rates
ruling at the balance sheet date. Differences on translation arising from
changes in the sterling value of overseas net assets, together with the
differences between profit and loss accounts translated at average rates and at
balance sheet rates, are shown as a movement on reserves and in the statement of
recognized gains and losses. Other exchange rate differences are dealt with in
the profit and loss account for the period.
 
Deferred taxation
Deferred taxation is provided on the liability method in respect of timing
differences except where the liability or asset is not expected to crystallize
in the foreseeable future. No deferred tax asset is recognised corresponding to
liabilities provided for in respect of post-retirement healthcare benefits.
Provision is not made for additional taxation which might be payable if profits
retained by overseas companies were distributed as dividends.
 
Healthcare and other obligations to employees
The Group provides healthcare and other benefits, including workers'
compensation benefits, to certain qualifying employees and former employees of
the Peabody companies and their dependants under the provisions of various
benefit plans or as required by US state or federal law. These benefits are
accrued and charged to the profit and loss account over the expected service
lives of the employees with the exception of pneumoconiosis (black lung)
benefits in respect of employees ceasing employment prior to 1 July 1973, which
are accounted for as payments are made. Pneumoconiosis benefits in respect of
employees ceasing employment after 30 June 1973 are estimated actuarially; the
last actuarial review was performed as at 1 October 1996. Other workers'
compensation benefits are also assessed actuarially.
 
Pension costs
The Group operates retirement benefit schemes in the UK, the US and Australia,
in accordance with local regulations and custom. The assets of the schemes are
held in separate funds administered by trustees.
 
The costs of providing pensions are charged to the consolidated profit and loss
account over employees' service lives. The pension costs relating to those
schemes which provide defined benefits are assessed in accordance with the
advice of qualified actuaries.

Included above are costs and overheads for the six months ended 31 March 1997
within Teplarny Brno of L15 million.
 
The reorganisation expense of L20 million in the six months ended 31 March 1997
reflects full provision for the reopening of Eastern's voluntary severance
scheme in its Networks business.
 
The reorganisation provision created on the acquisition of Eastern in 1995 of
L29 million was no longer deemed necessary and was reversed in 1996. A deferred
tax asset of L11 million, recognised in 1995 to reflect the taxation relief in
respect of this provision, was also reversed in 1996.
 
Other operating charges less other income for the six months ended 31 March 1997
includes operating lease rentals payable of L138 million (years ended 30
September 1996 L77 million, 1995 L20 million, 1994 L20 million) primarily in
respect of plant and machinery.

7.  EXCEPTIONAL ITEMS
 
During 1996, the Group received an interim dividend of L11 million and special
dividends (net of associated costs) totaling L165 million connected with the
flotation of The National Grid Group plc ("National Grid Group"). Amounts
credited to electricity customers in the form of a discount on electricity bills
connected with this flotation totalled L132 million.
 
The profit on disposal of First Hydro of L25 million in 1996 arose on the
disposal of the Group's interest in the pumped storage business of National Grid
Group.

9.  TAXATION CHARGE/(CREDIT) (CONTINUED)
The tax charge for the six months ended 31 March 1997 is net of a credit of L1
million in respect of an exceptional item. If full provision had been made for
deferred tax for the period ended 31 March 1997, the tax charge would have
decreased by L71 million (year ended 30 September 1996 increased by L31 million,
1995 Lnil, 1994 reduced by L6 million) being L38 million in respect of capital
allowances in excess of depreciation and L33 million in respect of other timing
differences. As a result of the stand-alone basis of providing for deferred tax,
the charge for deferred tax shown above was increased by L57 million for the
year ended 30 September 1996 (1995 L42 million, 1994 reduced by L5 million).
 
As a result of the surrender of group relief for nil consideration, together
with the taxation effects of the National Grid Group flotation, the tax charge
shown for the three years ended 30 September 1996 is not representative of the
charge that may arise following the Demerger Transactions.
 
A reconciliation of the tax charge at the UK statutory rate of corporation tax
to the actual tax charge is as follows:

ordinary shares for each of the three years in the period ended 30 September
1996, being the number of ordinary shares in the Company which were issued in
respect of the Demerger.
 
Earnings per share for the six months ended 31 March 1997 are based on 519
million ordinary shares. This excludes the 2 million shares held as at 31 March
1997 by The Energy Group Employee Benefit Trust which has waived its right to
dividends on the shares it holds.
 
Adjusted earnings per share are based on the same number of shares and the
profit for the relevant period after excluding the items relating to the
National Grid Group flotation, the profit on disposal of First Hydro, the
exceptional restructuring and reorganisation and the related taxation as

13.  FIXED ASSET INVESTMENTS (CONTINUED)
Following a detailed consideration of the nature of the joint venture agreement
governing Black Beauty Coal Company ("BBCC"), the Group's interest in that
operation is now accounted for on an equity accounting basis, rather than the
proportional consolidation basis which had historically been applied. This
change in treatment better reflects the nature of the Group's interest in the
operation, its revenues and its assets. A summary of the effect of this change
in accounting treatment on the Group balance sheet is shown below:

Each of the individual items in the summarised BBCC balance sheet at 30
September 1996 was included within the Group balance sheet as at 30 September
1996 under proportional consolidation. During the six month period ended 31
March 1997 adjustments have been made to remove these items due to the change in
treatment. The above BBCC balance sheet analysis as at 31 March 1997 is purely
for information purposes as it is only the Group's share of the net assets of
BBCC which is included within the consolidated balance sheet under "Fixed Asset
Investments -- Associated Undertakings." The balance at the start of the period
is shown as an adjustment in the above table of fixed asset investments.

Fair value adjustments were made to the book value of the assets and liabilities
of the above acquisition to bring them into alignment with the Group's
accounting policies and to adjust where applicable the carrying values of
certain assets and liabilities.
 
The above figures reflect a preliminary allocation of the purchase consideration
to the net assets and liabilities of the acquisition made in the period. The
preliminary allocation will be reviewed based on additional information up to 31
March 1998. The Directors do not believe that any net adjustments resulting from
such a review would have a material adverse effect on the Group.
 
For the year prior to acquisition, Teplarny Brno reported profit after tax of L4
million.
 
There were no significant acquisitions in the year ended 30 September 1994 and
the year ended 30 September 1996.
 
Eastern was acquired by Hanson on 18 September 1995. As explained above, Eastern
has been included in the balance sheet of the Group as at 30 September 1995 and
in its results from 1 October 1995. The Caballo and Rawhide mines were acquired
by Peabody on 1 November 1994.

The acquisition of Teplarny Brno would not have had a material impact on the
Group's results prior to acquisition.
 
21.  CONTINGENT LIABILITIES
 
Certain properties in the US in which the Group has or has had an interest are
subject to actual or potential environmental claims. The Directors have made a
L42 million provision, included in provisions for reclamation and environmental
obligations (Note 19), in relation to these claims, but significant uncertainty
exists as to whether these claims will be pursued against the Group in all cases
and, where they are pursued, the amount of the eventual costs and liabilities.
In the event that future costs and liabilities are in excess of amounts accrued,
the Directors do not anticipate that they will have a material adverse effect on
the consolidated results of operations, financial portion or liquidity of the
Group.
 
In February 1997 final determinations were made against The National Grid
Company plc ("National Grid") and its group trustees by the Pensions Ombudsman
on complaints by two pensioners in National Grid's section of the Electricity
Supply Pension Scheme ("ESPS") relating to the use of the surplus arising under
the actuarial valuation of the National Grid section as at 31 March 1992 to meet
certain additional costs arising from the payment of pensions on early
retirement pursuant to reorganisation or redundancy and certain additional
contributions. These determinations were set aside by the High Court on 10 June
1997 and the arrangements made by National Grid and its trustees in dealing with
its section's surplus were confirmed. The two pensioners have now appealed
against this decision. If a similar complaint were to be made against Eastern in
relation to its use of actuarial surplus in its section of the ESPS, it would
resist it, ultimately through the courts. However, if a determination were
finally to be made against it and upheld by the courts, Eastern could have a
potential liability to repay to its section of the ESPS an amount estimated by
the Directors to be up to L75 million (exclusive of any applicable interest
charges).
 
The Group is subject to business risks which are actively managed against
exposures.

</TABLE>
 
(b) Gas take or pay contracts
 
There are various types of contracts for the purchase of gas. Almost all include
"take or pay" obligations under which the buyer agrees to pay for a minimum
quantity of gas in a year. In order to help meet the expected needs of its
wholesale and retail customers. Eastern has entered into a range of gas purchase
contracts. As at 31 March 1997 the commitments under long-term gas purchase
contracts amounted to an estimated L2.2 billion (30 September 1996 L2.3 billion)
covering periods up to 18 years forward. The Directors do not consider it
likely, on the basis of the Group's current expectations of demand from its
customers as compared with its take or pay obligations under such purchase
contracts, that any material payments will become due from the Group for gas not
taken.

23.  PENSION AND POST-RETIREMENT HEALTHCARE
 
PENSIONS
 
The Group participates in several defined benefit pension plans in the UK, the
US and Australia which cover the majority of employees. The benefits for these
plans are based primarily on years of credited service and final average
pensionable pay as defined under the respective plan provisions.
 
The total cost of all pensions of the Group in the years ended 30 September
1994, 1995 and 1996 and the six months ended 31 March 1997, was L14 million, L13
million, L17 million and L10 million, respectively. The amount for 1996 includes
L4 million relating to UK employees and L10 million in respect of additional
one-off cash retirement costs for US employees.
 
In the US, Peabody sponsors four main defined benefit pension plans. With the
exception of one plan, assets are set aside in separate trustee-administered
funds. Each of these plans is assessed annually by independent qualified
actuaries using the projected unit method, the latest valuations being as at 30
September 1996. In addition, Peabody participates in two multi-employer plans.
In these plans, the assets contributed by the participating employers are
aggregated and the contributions payable are determined by independent qualified
actuaries in accordance with industry-wide agreements. Peabody also has a number
of defined contribution plans. Costs relating to the multi-employer and the
defined contribution plans are recognised as incurred.

23.  PENSION AND POST-RETIREMENT HEALTHCARE (CONTINUED)
In the UK, the majority of Eastern employees are members of the ESPS which
provides pensions of a defined benefit nature for employees throughout the
Electricity Supply industry. The ESPS operates on the basis that there is no
cross-subsidy between employers and the financing of Eastern's pension
liabilities is therefore independent of the experience of other participating
employers. The assets of the ESPS are held in a separate trustee-administered
fund.
 
The pension cost relating to the Eastern part of the ESPS is assessed in
accordance with the advice of independent qualified actuaries using the
projected unit method. The latest actuarial valuation was carried out as at 31
March 1995.
 
The total market value of the assets of the US plans, excluding the
multi-employer and defined contribution plans, was L255 million as at 30
September 1996. The market value of the assets of Eastern's section of the ESPS
was L681 million at 31 March 1995.
 
The assumptions which had the most significant effect on the results of the
valuations were that the rate of investment return would exceed salary increases
(exclusive of merit awards) by 2 1/2 per cent. per annum for the UK plans and by
an average 3 1/2 per cent. per annum in the US, and with investment returns in
the UK being assumed to exceed future pension increases by 4 per cent. per
annum. The actuarial value of the assets was sufficient to cover 104 per cent.
of the benefits that had accrued to members in the UK and 98 per cent. in the
US.
 
Provisions for liabilities and charges (Note 19) include a provision of L4
million (provision of L1 million at 30 September 1994 and L10 million at 30
September 1995, prepayment of L1 million at 30 September 1996) representing the
excess of the accumulated amount charged against the Group's profits in respect
of pension costs over the contributions paid to the plans concerned.
 
POST-RETIREMENT HEALTHCARE
 
The Group also provides post-retirement health care and life assurance benefits
under plans mainly in the US to certain groups of its retired and active
employees.
 
As at 31 March 1997 the accumulated post-retirement benefit obligation excluding
pensions, as assessed by independent qualified actuaries, for retirees and the
obligation for prior service costs of currently active employees is
approximately L576 million. The charge for the six months ended 31 March 1997
has been accrued based upon actuarial calculations determined in accordance with
required accounting standards. This resulted in the recognition of service costs
for benefits earned during the period of approximately L2 million, and interest
cost on accumulated benefit obligations of approximately L21 million. The
actuarial assumptions used to estimate the obligations vary according to the
claims experience and economic conditions relevant to each plan. It has been
assumed that the annual per capita cost of benefits will increase 6-8 per cent.
depending on claims experience and economic conditions relevant to each plan.
This rate is assumed to decrease 1/2 per cent. a year to 5 per cent. The
weighted average discount rate used in determining the accumulated
post-retirement benefit obligation was 7 1/2 per cent. as at 31 March 1997.

28.  RELATED PARTY TRANSACTIONS
 
During the six months ended 31 March 1997, a subsidiary of the Group has
purchased coal from Black Beauty Coal Company, a partnership in which the Group
has a 33 per cent. investment. The subsidiary purchased 37,645 tons of coal at a
cost of approximately L1 million during the six months ended 31 March 1997.

- --------------------------------------------------------------------------------
 
28.  RELATED PARTY TRANSACTIONS (CONTINUED)
Prior to the Demerger, the Group did not operate as a separate group, and
consequently there were a number of related party transactions between it and
the Hanson Group. These include transactions in respect of treasury, insurance,
taxation and other central services supplied by the Hanson Group to the Group.
These transactions have not been identified individually as it is not practical
to do so.
 
Hanson has agreed to provide the Group with business development and consultancy
services in the Far East for a period of three years following the Demerger. The
amounts payable for these services are not material.
 
29.  EMPLOYEE SHARE PLANS
 
The Group has the following employee share plans:
 
(a)   The Energy Group Sharesave Scheme which is available to all UK based
      employees of participating companies within the Group and those directors
      who are employees of participating companies and who devote more than 25
      hours a week to their duties. Employees who participate in this scheme
      have to enter into a monthly savings contract.
 
(b)   The Energy Group Executive Share Option Scheme which is administered by
      the Remuneration Committee of the Board of Directors of the Company ("the
      Remuneration Committee") and is available at its discretion to employees
      of the Group and those directors (other than Directors of the Company) who
      devote more than 25 hours a week to their duties.
 
(c)   The Energy Group Long-term Incentive Plan operates in conjunction with the
      Company's Employee Benefit Trust. The Plan is supervised and administered
      by the Remuneration Committee. The Plan may be made available to all
      employees and directors of the Group at the discretion of the Remuneration
      Committee, but the current intention is to limit it to the executive
      directors of the Company and certain senior executives of the Group.
 
(d)   The Energy Group Employee Benefit Trust is for the benefit of employees,
      ex-employees and the spouses and dependants of such employees or
      ex-employees of the Group. The purpose of the Trust is to facilitate and
      encourage ownership of the Company's shares.
 
(e)   The Peabody Plans are voluntary plans open to all applicable US based
      employees of Peabody (one plan is also open to hourly paid employees).

30.  DIFFERENCES BETWEEN UK GAAP AND US GAAP
 
The financial statements have been prepared under UK GAAP which differ in
certain respects from US GAAP.
 
The following is a summary of the principal differences between UK GAAP and US
GAAP that are significant to the Group and adjustments to profit for the year
end equity shareholders' funds (shareholders' equity reserves) which would be
required if the financial statements were to be restated under US GAAP.
 
GOODWILL
 
Under UK GAAP, goodwill arising on the acquisition of a subsidiary is set off
against reserves in the year in which that subsidiary is acquired. Under US
GAAP, such goodwill is capitalized and amortized through the profit and loss
account over its estimated useful life, not exceeding 40 years. For the purposes
of the reconciliations set out below, an estimated useful life of 25 years has
been adopted. Under UK GAAP, the gain or loss on the sale of a subsidiary
includes any goodwill previously set off against reserves. Under US GAAP, such
gain or loss includes any unamortized

THE ENERGY GROUP PLC
- --------------------------------------------------------------------------------
 
30.  DIFFERENCES BETWEEN UK GAAP AND US GAAP (CONTINUED)
goodwill relating thereto. For US GAAP purposes, the carrying amount of goodwill
is periodically compared with future potential cash flows over the remaining
amortization period.
 
TAXATION
 
Under UK GAAP, deferred tax is provided using the liability method for all
timing differences to the extent that it is probable that the liability will
crystallize in the foreseeable future. US GAAP require deferred taxation to be
provided in full, using the liability method on all temporary differences
between the tax and book bases of assets and liabilities.
 
Under US GAAP, valuation allowances with respect to deferred tax assets are
provided when it is considered more likely than not that all or a portion of the
deferred tax assets will not be realized. As discussed in Note 9, the tax borne
by the Group may not be representative of the charges it will incur following
Demerger and thus differs from the amount the Group in the three years ended 30
September 1996 would have borne as a stand-alone entity. US GAAP require taxes
to be allocated among the members of a group if they prepare separate financial
statements.
 
PENSION PLANS
 
Under both UK GAAP and US GAAP, the cost of providing pensions under the Group's
defined benefit schemes is charged to the consolidated profit and loss account
over the employees' service lives. US GAAP require that the projected benefit
obligations be matched against the fair value of the schemes' assets and that
adjustments be made to reflect any unrecognised obligations or assets in
determining the pension cost or credit for the period. US GAAP also prescribe
the basis for determining curtailment costs. In connection with the acquisition
of Eastern, under US GAAP, a prepaid pension cost of L119 million, equal to the
excess of Eastern's pension scheme assets over the related projected benefit
obligation at 30 September 1995, has been recognised.
 
PROVISION FOR RESTRUCTURING AND REORGANISATION
 
Under UK GAAP, the Group charged L20 million against profit in the six months
ended 31 March 1997 (and L29 million in the year ended 30 September 1995) in
relation to provisions for restructuring and reorganisation. Under US GAAP these
provisions would not have been permitted. The 1995 provision was reversed under
UK GAAP in the year ended 30 September 1996 as it was no longer required.
Accordingly, under US GAAP, this reversal has been removed in the reconciliation
below.
 
IMPAIRMENT OF LONG-LIVED ASSETS
 
The Group's accounting policy for impairment of long-lived assets was adopted
for the first time in the year ended 30 September 1996. This policy accords with
the requirements of Statement of Financial Accounting Standards ("SFAS") No.
121. Under UK GAAP, the change in accounting policy has been treated as a prior
year adjustment and, accordingly, the financial statements have been presented
on the basis of the revised policy with the effect of the change on prior years
reflected in invested capital at 1 October 1993. Under US GAAP, impairment
losses resulting from the application of SFAS 121 to assets to be held and used
are reported in the period in which the recognition criteria are first applied
and met as a component of continuing operations.
 
SUBORDINATED INCOME NOTE
 
Under UK GAAP, the 5 per cent. subordinated income note 2006 is recorded at its
nominal amount. Under US GAAP, this income note has been discounted at a rate of
13 per cent. per annum.
 
DIVIDEND
 
Under UK GAAP, dividends are recorded in the financial statements for the period
to which they relate. Under US GAAP, dividends are not recorded until they are
declared.
 
EXCEPTIONAL ITEMS
 
Under UK GAAP, the exceptional effects of the flotation of National Grid Group
have been shown separately in the consolidated profit and loss account and
operating profit and earnings per ordinary share are disclosed both before and
after this effect. Further, the gain on sale of First Hydro is reported as a
non-operating exceptional item after operating profit. Under US GAAP, the gain
on sale of First Hydro would have been included in the determination of
operating profit and disclosure of operating profit and earnings per ordinary
share before and after exceptional items is not permitted.

30.  DIFFERENCES BETWEEN UK GAAP AND US GAAP (CONTINUED)
 
CONSOLIDATED CASH FLOW STATEMENT
 
The consolidated statements of cash flows present substantially the same
information as that required under US GAAP. UK GAAP and US GAAP differ, however,
with regard to classification of items within the statements and as regards the
definition of cash and cash equivalents.
 
In 1996 the UK Accounting Standards Board revised the UK Financial Reporting
Standard No. 1, "Cash Flow Statements". The consolidated cash flow statement for
the six months ended 31 March 1997 set out on page F-4 has been prepared in
conformity with the revised standard and prior years have been restated to
conform with the new presentation. The principal differences between this
statement and cash flow statements presented in accordance with US GAAP are as
follows:
 
1. Under UK GAAP, net cash flow from operating activities is determined before
   considering cash flows from (a) returns on investments and servicing of
   finance and (b) taxes paid. Under US GAAP, net cash flow from operating
   activities is determined after these items.
 
2. Under UK GAAP, capital expenditure is classified separately, while under US
   GAAP, it is classified as an investing activity.
 
3. Under UK GAAP, dividends are classified separately, while under US GAAP,
   dividends are classified as financing activities.
 
4. Under UK GAAP, movements in short-term investments are not included in cash,
   but classified as management of liquid resources. Under US GAAP, short-term
   investments with a maturity of three months or less at the date of
   acquisition are included in cash.
 
The categories of cash flow activity under US GAAP can be summarized as follows:

The interest expense prior to the Demerger was affected significantly by the
financing arrangements of Hanson. Accordingly the allocation of interest expense
between the United Kingdom and Other for periods ending on or before 30
September 1996 is not considered meaningful. Consequently the analysis of profit
before taxation is only presented here for the six months ended 31 March 1997.
 
ADDITIONAL INFORMATION ABOUT FINANCIAL INSTRUMENTS REQUIRED BY US GAAP
 
Contracts for differences and electricity forward agreements
 
Almost all electricity generated in England and Wales must be sold to the Pool,
and electricity suppliers must likewise generally buy electricity from the Pool
for resale to their customers. The Pool is operated under a Pooling and
Settlement Agreement to which all licensed generators and suppliers of
electricity in Great Britain are party.
 
The Eastern Group utilizes contracts for differences ("CfDs") and electricity
forward agreements ("EFAs") to manage its net exposure to fluctuations in
electricity pool prices. CfDs and EFAs are contracts which fix the price of
electricity for an agreed quantity and duration by reference to an agreed strike
price. EFAs are similar in nature to CfDs, except that they tend to last for
shorter time periods and are based on standard industry terms rather than being
individually negotiated. Long-term CfDs are in place to hedge a proportion of
electricity purchases up to 2009. Up until 1998 the costs of such CfDs are
passed through to customers as part of franchise tariffs. From 1998 such CfDs
represent an annual commitment of approximately five terawatt hours ("TWh"),
falling on a linear basis to two TWh by 2005 and finally expiring in 2010. There
are no similar long-term commitments under EFAs.

30.  DIFFERENCES BETWEEN UK GAAP AND US GAAP (CONTINUED)
 
Estimates of the fair value of these contracts would be based upon assumptions
of a number of complex factors, in particular the anticipated long-term level of
Pool prices and appropriate market discount rates. It is not possible to
estimate the long-term level of Pool prices with reasonable accuracy because of
their inherent volatility. In addition, there is no readily identifiable market
through which they could be realised in an exchange. In view of the foregoing,
it is not practicable to ascribe a fair value of these contracts.
 
Approximately 60 per cent by volume of all of the Group's CfDs and EFAs in the
six months ended 31 March 1997 were contracted with National Power plc and
PowerGen plc.
 
Interest rate swaps
 
Interest rate swaps are used by the Group to convert fixed into floating rate
debt. The Group is exposed to credit loss in the event of non-performance by the
counterparties to the interest rate swaps. This exposure is managed by selecting
counterparties based on their credit ratings and by monitoring total exposure to

</TABLE>
 
The following methods and assumptions were used to determine the above fair
values:
 
(i)   Because of the unusual and specific nature of the fixed asset investments
      it is not considered practicable to estimate their fair value;
 
(ii)  The carrying amounts of current asset investments, short-term deposits and
      cash approximate their fair value;
 
(iii) The fair value of the 5 per cent. subordinated income note 2006 is based
      on estimated borrowing rates used to discount the cash flows to their
      present value. The fair value of the investment bonds is based on their
      quoted mid-market prices and excludes the value of the interest rate
      swaps; and
 
(iv)  The fair value of the interest rate swaps is based on the cancellation
      value of each swap quoted by the relevant bank counterparty.

The following table sets forth the funded status and amounts recognised in the
combined balance sheet at 31 March 1997 and 30 September 1996 for the Group's
defined pension plans excluding multi-employer plans. Of the total amounts of
assets shown in the note, approximately 25 per cent. applies to US defined
benefit plans.
 
Under purchase accounting, a fair value adjustment of L119 million, equal to the
excess of Eastern's pension plan assets over the projected benefit obligation,
was included as a prepaid pension cost under US GAAP at 30 September 1995.

The health care cost trend rate assumption has a significant effect on the
amounts reported. Increasing the assumed health care cost trend rates
one-percentage-point in each year would increase the accumulated postretirement
benefit obligation as of 31 March 1997 by L73.0 million. The effect of this
change on the aggregate of the service cost and interest cost components of net
periodic post retirement benefit costs for the six months ended 31 March 1997
would be an increase of L3.5 million.
 
The post-retirement benefit cost included the following components:

30.  DIFFERENCES BETWEEN UK GAAP AND US GAAP (CONTINUED)
ADDITIONAL INFORMATION ABOUT IMPAIRMENT OF LONG-LIVED ASSETS REQUIRED US GAAP
 
SFAS 121 requires impairment losses to be recognised on long-lived assets used
in operations when indicators of impairment are present and the undiscounted
cash flows estimated to be generated under various assumptions by those assets
are less than the assets' carrying amount, impairment losses under SFAS 121 are
measured by comparing the estimated fair value of the assets to their carrying
amount.
 
During the course of its financial year ended 30 September 1996, Hanson
commissioned independent valuations of each of its principal operating
businesses in connection with formulating its plans for their possible demerger.
These indicated, inter alia, possible impairment in certain of the Group's US
coal assets, arising from the cumulative effects of the Clean Air Amendments Act
1990 and weak demand and lower prices in certain markets. As a result, a
detailed evaluation of the Group's US coal assets was undertaken in accordance
with the principles laid down by SFAS 121.
 
Under US GAAP, a non-cash charge of L578 million would be recorded in the year
ended 30 September 1996 as a result of adopting the evaluation methodology of
SFAS 121, principally related to impairment of certain inactive and undeveloped
coal reserves.
 
Under US GAAP, prior to the adoption of SFAS 121, asset impairment was evaluated
at an operating company level based on the contribution of operating profits and
undiscounted cash flows being generated from those operations. Under the Group's
previous policy, assets used in operations, which consisted of multiple
operating companies, were evaluated for impairment based on gross margins and
cash flows generated by each separate operating company in a given business
cycle. No reduction in carrying value was required since, on that basis,
earnings and cash flows indicated no impairment in asset value.
 
SFAS 121 requires the impairment review to be performed at the lowest level of
asset grouping for which there are identifiable cash flows, a change from the
higher level at which the Group's previous accounting policy measured
impairment. The Group's economic grouping of assets was based on the markets in
which the operations compete, and in the coal segment consisted of both active
and inactive mines, as well as undeveloped properties. Evaluation of assets at
the lower grouping level indicated an impairment of certain of those assets.
This policy does not allow off-setting of surpluses from assets whose future
cash flows exceed current book values. Where shortfalls in cash flows compared
to carrying values arise, the assets are written down to fair value, determined
by discounted future cash flows from the assets or estimated current market
values.
 
CONCENTRATION OF CREDIT RISK
 
The Directors did not consider there to be any significant concentration of
credit risk as at 31 March 1997.
 
IMPACT OF NEW ACCOUNTING STANDARDS
 
Environmental remediation liabilities
 
Statement of Position No. 96-1 "Environmental Remediation Liabilities" ("SOP
96-1") was issued in October 1996. The statement provides authoritative guidance
on specific accounting issues that are present in the recognition, measurement,
display and disclosure of environmental liabilities. The provisions of the
statement are effective for fiscal years beginning after 15 December 1996. SOP
96-1 is not expected to have a material impact on the financial position or
results of operations of the Group presented under US GAAP.
 
Earnings per share
 
In February 1997, FAS 128 "Earnings per Share" was issued. The provisions of
this statement must be adopted for accounting periods ending after 15 December
1997. Earlier adoption is not permitted. FAS 128 simplifies the provisions
relating to the computation of earnings per share ("EPS") previously found in
APB Opinion No. 15 "Earnings per Share" ("APB 15"). It replaces the presentation
of primary EPS with basic EPS and requires dual presentation of basic and
diluted EPS on the face of the income statement for all entities with complex
capital structures. EPS for US GAAP purposes are not computed using the
methodology prescribed by APB 15 as the impact of doing so is not material. The
adoption of FAS 128 by the Company is not expected to have any material impact
on the EPS amounts previously reported under US GAAP.

Accounting and disclosure of stock based compensation
FASB Statement of Financial Accounting Standards No. 123 -- "Accounting for
Stock-Based Compensation" which establishes financial accounting and reporting
standards for stock-based employee compensation plans, is effective for
accounting periods beginning after 15 December 1995. The Statement provides the
option to continue under the accounting provisions of Accounting Principles
Board Opinion No. 25, "Accounting for Stock Issued to Employees" (APB No. 25),
providing that proforma footnote disclosures of the effects on net income and
earnings per share, calculated as if the new method had been implemented, are
included. The Company has elected to continue under APB No. 25, but the proforma
disclosures have been omitted, as the effects on net income and earnings per
share are not material.

31.  SUBSEQUENT EVENTS
On 14 April 1997 Eastern Electricity plc issued L200 million 8.75% bonds due
2012.
 
On 24 April 1997 Eastern issued promissory notes of CZK 2,900 million
(approximately L59 million) to Ceska Sporiteina a.s. in the Czech Republic
redeemable no later than 29 April 2004. The notes are secured by the Group's
investments in Severomoravska Energetika a.s. and Teplarny Brno a.s.
 
On 19 May 1997 the Group completed its acquisition of Citizens Lehman Power
L.L.C., which has been renamed Citizens Power L.L.C. The acquisition involved an
initial payment of L12.5 million in cash, plus a payment deferred until 31 March
2000, equivalent to the net assets as of 30 June 1997. There will be additional
purchase consideration linked to profit goals up to 2002, subject to a maximum
consideration for the entire transaction of $120 million.
 
At 12 June 1997 the Group's shareholding in Teplarny Brno a.s. had increased to
70.3 per cent. at an additional cost of L4 million.
 
On 2 July 1997 UK government confirmed its previously-announced intention to
charge a windfall levy on certain privatised UK utilities. The Directors
estimate Eastern's, and therefore the Group's liability to be approximately L112
million. This amount will be paid in two equal installments which fall due in
December 1997 and December 1998.
 
On 10 June 1997 the company announced it was in discussions with PacifiCorp
which might lead to a combination of the two groups through a recommended cash
offer for The Energy Group PLC.
 
On 13 June 1997 the company announced that it had agreed terms with PacifiCorp
for a recommended cash offer to be made by a wholly owned subsidiary of
PacifiCorp for The Energy Group PLC.
 
On 1 August 1997 the UK Secretary of State for Trade and Industry referred the
proposed acquisition of the Group by PacifiCorp to the Monopolies and Mergers
Commission. As a result of the referral, the recommended cash offer
automatically lapsed in accordance with its terms.

15:10 01 Aug RNS-Energy Group PLC <TEG.L>Response Re MMC Referral
RNS No 2196v
ENERGY GROUP PLC
1st August 1997
 
In response to the statement made today by Mrs Beckett referring PacifiCorp
Acquisitions' offer for The Energy Group PLC to the Monopolies and Mergers
Commission, Derek Bonham, Chairman of the Energy Group said:
 
"We are surprised and disappointed at Mrs Beckett's decision, particularly as
PacifiCorp had indicated their willingness to comply with all assurances
required by the UK regulatory authorities. Over 61 per cent of our shareholders
have already demonstrated their support for this transaction. We will cooperate
with the MMC in their deliberations, meanwhile we will continue to develop the
businesses of the Group in line with our stated strategy to become one of the
world's leading international energy suppliers."

                  TWO NEW BOARD APPOINTMENTS AT EASTERN GROUP
 
EASTERN GROUP, ONE OF THE COUNTRY'S LEADING GAS AND ELECTRICITY GROUPS, HAS
ANNOUNCED THE APPOINTMENTS OF TWO NEW BOARD DIRECTORS.
 
Dr David Huber joins the company on September 1, 1997, as Human Resources
Director. He has wide experience in the fields of human resources and retail
markets having previously worked for major corporations including Dunlop and the
Burton Group before becoming HR Director at Safeway Stores.
 
Jim Whelan was appointed Managing Director, Power and Energy Trading, on July 1.
He joined Eastern in 1993 and has successfully lead the company's power and
energy trading activities to be a prominent force in UK energy markets. His
experience in energy market transactions came to the fore in the 1996
negotiations for Eastern's leasing of five coal-fired power stations from
National Power and PowerGen. Jim has extensive experience of the UK energy
sector and international commodity and energy trading.
 
John Devaney, Eastern's Executive Chairman, said: "Both appointments bring
significant experience and expertise to the Board at a time when the group
continues to grow rapidly and also meet the challenges of full deregulation in
its gas and electricity markets."

                      RESULTS -- IN LINE WITH EXPECTATIONS
 
                              FINANCIAL HIGHLIGHTS
                        (COMPARED ON A PRO FORMA BASIS)
 
 --   TURNOVER UP 19 PER CENT TO L1033 MILLION.
 
 --   OPERATING PROFIT OF L96 MILLION DESPITE ABSORBING SEASONAL FIRST QUARTER
      LOSSES ON COAL STATIONS.
 
 --   POSITIVE PROFIT CONTRIBUTIONS FROM RECENT ACQUISITIONS IN THE USA AND THE
      CZECH REPUBLIC.
 
 --   CONTINUING POWER STATION AND DEVELOPMENT PROJECTS IN AUSTRALIA, TAIWAN AND
      INDIA.

The Group's businesses have performed above or in line with expectations with
useful profit contributions from acquisitions in the USA and the Czech Republic.
 
Group turnover for the quarter rose by 19 per cent from L869 million to L1,033
million, and underlying operating profit was 14 per cent above the same period
last year. However, operating profit of L96 million was 2 per cent down after
absorbing approximately L20 million of seasonal losses on the UK coal-fired
power stations. These stations only came into the Group's control in the second
quarter of fiscal 1995/6.
 
A one off provision of L112 million has been taken for the windfall levy.
 
COAL
 
Turnover for the quarter increased to L354 million despite mild spring weather
in the USA that reduced coal consumption and power output by one per cent below
the previous year's level. Profit improved by 5 per cent to L40 million. On a
dollar basis, operating profit increased 11 per cent but was moderated by
exchange rate movements.
 
POWER
 
Results from the power business show an increase in turnover to L649 million and
in profit to L17 million despite absorbing first quarter losses at the
coal-fired stations.
 
                                                                      Cont . . .

The coal-fired stations' performance continued to exceed our original
expectations at close to 96 per cent availability.
 
Citizens Power, the acquisition of which was completed in May 1997, has produced
a positive first quarter contribution and the gas business of Eastern continues
to expand; domestic customers now exceed 120,000.
 
NETWORKS
 
Results for the networks business for the first quarter are down on the
comparable period last year, with turnover at L105 million and profit at L45
million. This is largely as a result of the regulatory review which has only
been partly offset by further cost reductions. In addition units distributed
were slightly lower, due mainly to mild weather.
 
OUTLOOK
 
Derek Bonham, Chairman of The Energy Group, said:
 
"Prospects for the Group are in line with those described at the time of
demerger. Our core businesses are continuing to perform strongly and we are
pleased with the initial contribution from our new investments."

FOR IMMEDIATE RELEASE
Aug. 19, 1997
 
CLIMATE CHANGE TREATY WOULD
CURB U.S. ECONOMIC GROWTH,
JEOPARDIZE ELECTRICITY SUPPLY
 
ST. LOUIS, Mo., Aug. 18 -- An international climate treaty being negotiated this
year to reduce carbon dioxide (CO(2)) emissions at power plants will curb U.S.
economic growth by jeopardizing the electricity supply, according to a new study
by Resource Data International, Inc. (RDI).
 
     The study examines how growth in the U.S. electricity supply helps drive
economic growth as measured by the Gross Domestic Product (GDP). About 56
percent of all U.S. electricity is generated from coal which is the lowest cost
fuel. Coal's primary component is carbon, and according to the Clinton
Administration, reducing coal use is the most likely scenario to control CO(2)
emissions.
 
     The study considered the effects of removing a significant proportion of
coal from the mix of resources that generate electricity and replacing it with
alternate sources.
 
     RDI concluded that no single alternative resource or combination of natural
gas, nuclear, hydroelectric and renewables such as solar or wind, can replace
coal to generate electricity and sustain current levels of U.S. economic growth
to meet even the most modest climate treaty proposal that would stabilize CO(2)
emissions at 1990 levels.
 
     The Clinton Administration has indicated that stabilizing emissions at 1990
levels by 2010 would require a tax of $100 on each ton of CO(2). The study found
that reducing CO(2) emissions to 1990 levels with a tax of this magnitude
drastically limits electricity supplies after 2005, reducing GDP growth by up to
$1.314 trillion, or 14 percent by 2010, and up to $16.823 trillion over a
10-year period.

CLIMATE CHANGE TREATY -- ADD ONE
 
     The RDI study also found that the economic impacts of the current CO(2)
reduction proposals will fall unevenly across the United States. The nation's
heartland will be hardest hit because interior regions lack hydroelectric and
nuclear generating resources and rely upon on Inexpensive coal-generated
electricity for 72 percent of their energy. Inexpensive electricity is also why
energy-intensive industries are more heavily concentrated in the U.S. interior.
Seaboard economies tend to be more service-oriented.
 
     RDI, an independent energy research group in Boulder, Colo., was retained
by St. Louis-based Peabody Holding Company, Inc., the world's largest private
coal producer, to study the economic effects of current proposals for a new
treaty on climate change. The new treaty will be considered at the December 1997
United Nations conference in Kyoto, Japan, where binding limits for the
mandatory reduction of carbon dioxide emissions in developed nations will be
debated.
 
     The proposed treaty will require the United States and other developed
nations to control CO(2) emissions, while China and other developing nations --
many of them major international trade competitors -- will be exempt from
binding limitations. The U.S. Department of Energy projects that, under current
conditions, the United States will contribute less than 19 percent of global
CO(2) emissions by 2015 compared to 58 percent from developing nations.
 
     The RDI study concludes that: "In short, there will be no benefit to global
climate. At the same time, the U.S. economy will be more at risk than either the
other [developed] nations or the nations that will be exempt from any potential
Kyoto treaty."

The Economic Risks of Reducing
the U.S. Electricity Supply
CO(2) Control and the U.S. Electricity Sector
 
EXECUTIVE SUMMARY
 
In response to international efforts to address perceived global climate change
impacts, the United States has expressed commitment to the goal of reducing
carbon dioxide ("CO(2)") emissions to 1990 levels, or lower. To that end, the
Department of Energy and the Environmental Protection Agency have formed an
Interagency Analytical Team ("IAT") to work with outside economists in
determining the impacts associated with various proposals for emission
reductions, timetables, and mechanisms for attaining reductions.
 
This study focuses on the U.S. electricity sector and identifies the risks that
would be posed to the economy by reducing CO(2) emissions to 1990 levels in that
sector. These risks are quite great and would provide no tangible benefit, since
the nations with the fastest growing CO(2) emissions will be exempt from any
treaty that may be signed in Kyoto, Japan later this year.
 
Specific findings include:
 
CURRENT CO2 CONTROL PROPOSALS WILL PUT THE U.S. ECONOMY AT RISK
 
 --Growth in the U.S. economy is tied to growth in electricity supply, with
   current electricity-to-Gross Domestic Product ("GDP") ratios at 1.34% growth
   in electricity associated with each 1% growth in GDP;
 
 --Reducing CO(2) to 1990 levels will limit the annual growth rate in the supply
   of electricity between 1995 to 2015 to 0.83%, down from 1.45% under the
   Department of Energy's projected business-as-usual scenario. Neither natural
   gas nor CO(2) neutral generating resources will be able to offset this supply
   restriction;
 
 --Therefore, up to $1.314 trillion, or 14% of GDP, will be at risk in 2010 and
   up to $16.823 trillion cumulatively from 2005 to 2015.
<PAGE>   186
 
Proposed CO2 Emission Trading Proposals are not a Panacea
 
 --Clinton Administration is using the success of the acid rain sulfur dioxide
   ("SO(2)") trading program to suggest that CO(2) trading will limit compliance
   costs. However, the two programs differ fundamentally;
 
 --While the EPA distributes SO(2) emission allocations at no cost, the
   Administration proposes to auction CO(2) allocations. Such an auction would
   mimic the effects of a carbon tax, with the federal government collecting at
   least $133 billion annually from all sectors and $50 billion from the
   electricity sector alone. The idea that "recycling" of these revenues will
   counterbalance the economic consequences of both the "tax" and the costs of
   compliance is an unproven presumption;
 
 --The success of SO(2) trading lies in the ability of power plants to switch
   from high sulfur to low sulfur coal sources. Because low sulfur coal is now
   generally cheaper than high sulfur coal, over-compliance with the acid rain
   program often comes as a windfall. There are no "low carbon" coal sources,
   and natural gas is a higher cost fuel alternative.(1)
 
CO2 Stabilization will Disproportionately Impact the U.S. Interior
 
 --The Eastern and Western Coastal regions of the country have greater access to
   hydroelectric, nuclear, natural gas, and renewable energy resources than the
   Interior regions and therefore generate electricity that is less
   carbon-intensive than the interior. Where the Interior regions relied on coal
   for 72% of their electricity generation in 1995, the Coastal regions relied
   on coal for only 35%;
 
 --The economies of the Interior regions are more electricity-intensive than the
   economies of the Coastal regions. In 1995, the Interior regions consumed 0.51
   terraWatthours of electricity per billion dollars of Gross State Product
   ("tWh/GSP"), compared to 0.38 tWh/GSP for the Coastal regions;
 
 --Therefore, because the Interior regions rely on more carbon-intensive energy
   resources for electricity and require more of this carbon-intensive
   electricity per unit of GSP than the Coastal regions, the Interior regions
   will bear the brunt of any CO(2) stabilization effort.

    (1) There are slight differences between the carbon contents of bituminous
    and sub-bituminous coals and lignite, but these are insignificant in
    relation to sulfur differentials.
<PAGE>   187
 
U.S. Efforts to Reduce CO2 will have Diminishing Returns
- ---------------------------------------------------------------
 
 --The U.S. emitted 23% of global CO(2) emissions in 1995, but is projected to
   emit only 19% by 2015 under a business-as-usual scenario;
 
 --China and other non-OECD Asian nations emitted 23% of global CO(2) emissions
   in 1995, but are projected to emit 33% by 2015 under a business-as-usual
   scenario;
 
 --Only the Annex 1 nations (including the U.S. and OECD, as well as certain
   Eastern European countries) will be required to control CO(2) emissions under
   the Kyoto treaty, while China and all other non-OECD nations will be exempt.
   Thus, even if the OECD reduces its carbon emissions by 916 million metric
   tonnes ("mmt") by 2015 to meet 1990 levels, the non-OECD nations will still
   increase emissions by 2,360 mmt.

                         DUAL-FIRING PLANS FOR DRAKELOW
                           AND RUGELEY POWER STATIONS
 
EASTERN GENERATION, BRITAIN'S FOURTH LARGEST ELECTRICITY GENERATOR AND PART OF
EASTERN GROUP, TODAY UNVEILED PLANS TO INTRODUCE NATURAL GAS FIRING ALONGSIDE
COAL AT DRAKELOW AND RUGELEY POWER STATIONS.
 
The conversion plans, which are being submitted to the Department of Trade and
Industry for approval, will allow the stations to burn gas, coal or a
combination of both.
 
The L40 million investment includes the cost of laying six kilometres of
underground gas pipelines to each site. The gas pipes will be laid under mainly
agricultural land and care will be taken to minimise any disruption during
construction.
 
The plant modifications and pipeline laying could begin as early as April 1998
with dual-firing starting in July 1998.
 
Rugeley (Staffordshire) and Drakelow (South Derbyshire) each generate up to
1,000MW of electricity. Together the stations could burn up to 5.5 million
therms of gas each day.
 
The gas will be supplied by Eastern Power and Energy Trading from its expanding
portfolio of contracts. The company, one of Britain's largest independent
shippers of natural gas, is a sister company to Eastern Generation within
Eastern Group.
 
The advanced dual-firing technology will help in the management of station
emissions in the face of increasingly tight regulations. Burning natural gas
produces no sulphur dioxide, less nitrogen oxides and carbon dioxide and no dust
when compared to conventional coal firing.
 
John Devaney, Eastern Group's Executive Chairman, said: "This significant
investment will help secure the long-term future of generation on both sites."

NOTE TO EDITORS
 
Eastern Group currently owns, operates or has interest in eight power stations
in Britain representing around 10 per cent of the country's total generating
capacity. Its portfolio consists of a mix of combined-cycle gas turbine and
coal-fired stations.
 
The capacity was increased in 1996 as a result of leasing agreements for five
coal-fired stations -- Rugeley, Ironbridge and West Burton from National Power
and High Marnham and Drakelow from PowerGen.

                      EASTERN KICKS-OFF BIG SAVINGS ON GAS
 
GAS BILL SAVINGS OF AROUND 20% ARE IN THE PIPELINE FOR MILLIONS OF HOMES ACROSS
EASTERN ELECTRICITY'S REGION.
 
Eastern Natural Gas, sister company to Eastern Electricity, today becomes the
first rival to British Gas to kick-off its sales and customer awareness
campaign -- starting the countdown to full competition next year.
 
Both companies are part of Eastern Group, a nation-wide supplier of electricity
and natural gas.
 
Eastern, already one of Britain's biggest gas suppliers, currently offers an
average reduction of 20% off British Gas bills. Customers switching to direct
debit are saving up to 24.6% -- or around L100 on a typical L400 annual gas
bill.
 
More than 250,000 homes have signed with Eastern in those parts of the country
already free to choose from rival gas suppliers -- the south-west, south-east
and north-east of England and Scotland.
 
Ofgas, the industry watchdog, plans to see competition "go live" in May next
year in Norfolk, Suffolk, Essex, Cambridgeshire, Buckinghamshire, Bedfordshire
and Hertfordshire. Greater London boroughs are expected to follow in June.
 
Eastern is kicking-off with football ground advertising. Fully trained sales
representatives are spearheading the campaign region-wide from November 1.
 
Jonathan Baggott, Eastern's gas sales and marketing manager, said: "One in four
homes are now switching away from British Gas in places where competition has
already started. We have been looking forward to playing on 'home-turf' where
people are already familiar with Eastern as their local electricity supplier."
 
He added: "Eastern aims to secure more than 1.5 million new gas customers across
Britain by the turn of the century."

gas/2
 
Switching suppliers is simple. Eastern will use existing pipes and meters and
will bill customers directly. BG Transco is still responsible for leaks and
emergencies.
 
In addition to cheaper gas, Eastern also offers a full range of other services
including boiler servicing and emergency cover and bill payment protection.
 
A new gas sales inquiry line, charged at the local rate, is now available on
0345 236236.

THE ENERGY GROUP WINS BID FOR TURKISH GENERATION PLANT
 
The Energy Group, through its subsidiary, Peabody, together with NRG and Koc
Holding, have won a bid to acquire the 450 megawatt Kangal coal-fired generation
plant in central Turkey for $125 million.
 
The consortium interest is split: Koc 50%, Peabody 25% and NRG 25%. The bids are
subject to the negotiation of definitive agreements. The consortium has
submitted bids for other distribution and generation assets which are still
under evaluation.
 
Power from the Kangal station will be sold to TEAS, The Turkish national power
company, under a 20-year power purchase agreement. The agreement which will be
denominated in US dollars will contain minimum take-or-pay provisions. The plant
will be retrofitted with up-to-date technology to improve its environmental
performance significantly.
 
"This project is a further step in the realisation of The Energy Group's
strategy to develop as an international, integrated energy company", said Derek
Bonham, Chairman of The Energy Group. "The Kangal power station represents a
significant opportunity to acquire a quality asset which will produce immediate
earnings enhancement."

NOTES TO EDITORS
 
The disposal is part of the Turkish government's efforts to ensure a more
reliable and cost-efficient supply of energy by privatising its electric
distribution, generation and related coal mining assets. The Turkish economy is
growing at a rapid pace and growth in electricity demand is projected to be much
higher than that in most of Europe or the United States. The electricity growth
rate in Turkey is projected to be 6 to 8.5 per cent annually.
 
The Energy Group is a diversified international energy company which includes
Peabody, the world's largest private coal producer; Eastern, one of the leading
integrated electricity and gas companies in Great Britain; and Citizens Power,
one of the top five power marketers in the United States.
 
NRG is a wholly owned subsidiary of Northern States Power Company, which owns
and operates more than 7000 MW of coal, gas, nuclear, hydro and alternative
fuel-fired plants in the United States. NRG has significant investments in
Germany, Australia, Bolivia, the Czech Republic and the United States.
 
Koc Holding, founded in 1926, is the largest conglomerate in Turkey and a
Fortune Global 500 corporation.

available to L870,000.
 
Derek Bonham, Chairman of The Energy Group, said:
 
"I have always admired the drive, ambition and enthusiasm of the National Youth
Theatre, qualities which I believe are mirrored at The Energy Group. So I am
delighted that we are able to support them via this sponsorship which will cover
a substantial part of their core costs."
 
"It is in the best interest of business to encourage young people's creative
potential and not to overlook the benefits which drama and the arts can offer in
terms of training, education, self-confidence and long term contribution to
society."

                          SCOTLAND AND THE NORTH EAST.
 
Eastern Natural Gas, already one of Britain's biggest gas suppliers, has signed
around 200,000 new customers in Scotland and the North East -- representing
approximately half the households switching from November 1.
 
ENG, part of Eastern Group, a nation-wide provider of electricity and natural
gas, has signed around 108,000 homes in the North East and 92,000 in Scotland.
 
Ofgas announced today that more than 400,000 households out of a market of 2.5
million have signed to switch from British Gas in the latest competition phase.
 
Eastern offers an average reduction of 20% off British Gas bills. Customers
switching to direct debit are saving up to 24.6% -- or around L100 on a typical
L400 annual gas bill.
 
John Devaney, Executive Chairman, Eastern Group, said: "We're delighted with the
results of our sales campaign particularly in an area where Eastern was a new
name with households. We're already active in the south west and south east of
England and aim to secure 1.5 million new domestic gas customers nation-wide by
the turn of the century."

                         EASTERN POWERS INTO NORD POOL
 
Eastern Power and Energy Trading, part of Eastern Group, has become the first
British company to buy and sell electricity in the Norwegian and Scandinavian
power market.
 
The market, known as Nord Pool, was the world's first commodity exchange for
electrical power when it was established in 1993.
 
Easter is trading from Ipswich -- making it the first non-Scandinavian Nord Pool
member to operate remotely.
 
Unlike its UK operations, Eastern is trading for the first time on the
electricity futures market -- where the buying and selling is on paper and there
is no physical delivery of the electricity.
 
Jim Whelan, Managing Director of Eastern Power and Energy Trading, said:
"Joining Nord Pool is part of our strategic development overseas. It is a very
attractive way of gaining a closely controlled exposure and experience of a
foreign market."

     Derek Bonham, Chairman said: "The Energy Group has made an impressive start
to life as an independent company. With underlying operating profit up 12%, the
financial results are both encouraging and in line with expectations. We are
particularly well positioned to profit from the emerging competitive UK gas and
electricity sectors as well as the deregulating US energy market. Developments
in this period underpin our ambitions to become a leading international
integrated energy company."
 
     The Energy Group announces results for the period 1 April to 30 September

FINANCIAL RESULTS
 
Group turnover for the six months to 30 September 1997 was L2,007 million, an
increase of 7% on the same period last year. Operating profit for the period was
L187 million (pro forma 1996: L196 million) before the exceptional costs
associated with PacifiCorp's bid and restructuring costs within EASTERN.
Earnings per share, before exceptional items, fell to 17.7p (pro forma 1996:
21.7p). As reported in our first quarter results, compared with last year, these
results were adversely affected by some L20 million of normal seasonal losses
associated with the coal-fired power stations we leased in July 1996. Excluding
this, and using consistent exchange rates, underlying operating profit has grown
by more than 12%.
 
As reported, the L112 million cost of the windfall tax was fully provided for in
the first quarter. The underlying tax rate for ordinary activities in the six
months to 30 September 1997, before the windfall tax, was 26.3%.
 
In October the group successfully issued $500 million of bonds due for repayment
in 2017/2027, adding to the long term stability of our financial base.
 
DIVIDEND
 
An interim dividend of 8.0 pence per share will be paid on 9 January 1998 to
ordinary shareholders on the register on 19 December 1997. Subject to prevailing
circumstances, we expect to pay a further dividend in August 1998.
 
                                                                       cont. . .

PACIFICORP'S OFFER
 
PACIFICORP'S recommended offer for THE ENERGY GROUP of 690 pence per share
lapsed on 1 August 1997, when the UK Secretary of State for Trade and Industry
referred its bid to the Monopolies and Mergers Commission. We are co-operating
fully with this enquiry and also with the US regulatory authorities, who are
conducting their own reviews of the proposed merger.
 
REVIEW
 
The six months to 30 September 1997 have been a period of significant
development for THE ENERGY GROUP. In May we completed the acquisition of
CITIZENS POWER, one of the top ten electricity trading businesses in the USA.
This is a key element in our strategy of building an integrated energy company
in North America. Citizens is already working closely with PEABODY to market
jointly a range of new trading-based products to help utilities compete more
effectively in the deregulating US electricity markets. EASTERN continues to
make considerable headway in the UK gas supply market and is now one of the
largest suppliers after Centrica plc. We intend to be a major national player in
both the electricity and gas markets. The Energy Group has also announced major
energy projects in Poland, Turkey, Taiwan and the UK.
 
                                                                      cont . . .

TRADING
 
COAL
 
     PEABODY produced 83.5 million (86 million) tons of coal in the period and
continues to lead the US coal industry with a 14% share of the coal market. Its
steam coal products were used to generate over 9% of all electricity produced by
US electric companies. Turnover for the six months decreased 6% to L691 million
(L733 million) and operating profit declined 3% to L85 million (L88 million).
However, these results are distorted by the impact of the strong L:$ exchange
rate in the period. On a US dollar basis, turnover increased 1% to $1,137
million ($1,131 million). Operating profit was also up 3% to $140 million ($136
million) for the period. These figures included the favourable impact of a coal
supply agreement restructuring of $38 million, partially offset by reduced
demand for coal for electricity due to mild weather. Earnings improved at
PEABODY'S Australian operations and at the Powder River Coal Company.
 
     In Australia, PEABODY is continuing to expand the Warkworth Mine and to
construct a new mine at Bengalla in New South Wales to serve the fast-growing
Asia/Pacific Rim market. Initial shipments from Bengalla are expected to begin
in early 1999.
 
     PEABODY is also continuing with its competitiveness initiatives, including
productivity investments and consolidation of production. Our US mines achieved
record safety results, with a 20% year on year improvement, and an 80%
improvement since 1990.
 
                                                                       cont. . .

POWER
 
     Turnover in our POWER business increased by 15% to L1,248 million.
Operating profit fell by L8 million to L31 million due to the adverse impact of
seasonal losses referred to earlier.
 
     EASTERN'S UK power stations, notably the 5,949MW coal-fired portfolio, have
undergone routine summer maintenance during this half year and are well
positioned for the important winter months ahead. The 360MW CCGT power station
at Peterborough continued to achieve very high levels of availability throughout
the period, the 340MW CCGT power station at King's Lynn is completing its
commissioning phase and plans for further development of previously announced
new generation facilities are in advanced stages of the planning and approval
process. Eastern also intends to introduce dual-firing for coal and gas for
2,022MW of existing capacity at Drakelow and Rugeley to manage increasingly
tight emission regulations more effectively.
 
     The growth of EASTERN'S domestic gas retail business has been impressive,
adding to its strong position in the industrial and commercial markets. EASTERN
NATURAL GAS serves domestic customers in those parts of the south west and the
south east of England which are already open to competition and is winning
customers in Scotland and the north east. It has now signed up over 300,000
customers.
 
     EASTERN ELECTRICITY'S retail business continues to perform well in those
parts of the UK electricity market which are open for competition, with around
13% of eligible commercial sites in this market. We are currently on target to
be one of the four REC's fully ready for competition from 1 April 1998. Plans to
serve the national residential and small business electricity markets are well
advanced, including the recent launch of the innovative 'EcoPower' tariff.
 
                                                                         cont...

We are still in discussion with the electricity regulator about his price
proposals for electricity supply for the two years from 1 April 1998, and will
make a further announcement shortly. We welcome in principle the move to maximum
price caps as a means of facilitating competition in both the retail and
wholesale markets.
 
Following the demerger from Hanson PLC the group retained L68m of provisions
against long-term electricity contracts. We are now examining the implications
of a fully competitive market on these provisions against certain long term
electricity contracts entered into after privatisation, with the possibility
that provisions might need to be increased.
 
In the USA, CITIZENS POWER increased electricity and gas trading volume by 334%
over the comparable period in 1996. Since its acquisition, Citizens Power has
completed additional non-utility generating restructuring agreements, providing
it with a continuing earnings stream and has established a state-of-the-art
energy trading floor which co-ordinates with PEABODY in the marketing of new
combined fuel/power arrangements for the deregulating US electric utility
industry.
 
In September we reached an agreement to acquire a 49% interest in the
development of three 70MW co-generation projects in Poland. As part of a
consortium in which we have a 25% interest, we have recently won a bid to
acquire a 450MW coal-fired generation plant in central Turkey with a related

become involved in this kind of project in Taiwan.

1.  BASIS OF PREPARATION OF ACCOUNTS
 
The results for the six months to 30 September 1997 are unaudited. The
accounting policies are as stated in the Report and Accounts for the six months
ended 31 March 1997, together with the additional policy described below. The
figures for the six months ended 31 March 1997 are an extract from the full
published financial statements that have been delivered to the Registrar of
Companies, and on which the auditors have issued an unqualified report.
 
The group's recent acquisition, Citizens Power, provides contract restructuring
services to the energy industry. In connection with these activities, the group
has adopted the following accounting policy:
 
    Assets and liabilities associated with contract restructuring activities are
    marked to market. Movements in the market value are recognised in the profit
    and loss account in the period of change. In the absence of a readily
    available market price, fair value based on discounted cash flows is used.
 
2.  PRO FORMA INFORMATION
 
a)  The pro forma information for the year ended 31 March 1997 and for the six
    months ended 30 September 1996 has been extracted from audited financial
    returns for the period. The information has been prepared on a consistent
    basis to that presented in the group's listing particulars issued in January
    1997 and to the pro forma information provided in the group's report and
    accounts for the six months ended 31 March 1997.
 
b)  Pro forma central charges of L15 million in the year to 31 March 1997 and L7
    million in the six months to 30 September 1996 have been included in pro
    forma operating profit for these periods. In the group's listing particulars
    these charges were identified, but not included in the pro forma results.
 
c)  Pro forma net interest payable for the year ended 31 March 1997 is based on
    the actual interest charges borne by the individual operating entities which
    now comprise the group, increased for an additional pro forma interest
    charge calculated as 7.5% of the actual additional net debt allocated to the
    group by Hanson on demerger.
 
    Pro forma net interest payable for the six months ended 30 September 1996 is
    calculated on a similar basis, but using an additional pro forma interest
    charge which is based on the additional net debt and average interest rate
    assumed in the group's listing particulars.
 
                                                                         cont...

d)  The pro forma tax charge for the year ended 31 March 1997 has been
    calculated at the same effective rate before exceptional items as that which
    existed for the six months ended 31 March 1997.
 
    The pro forma tax charge for the six months ended 30 September 1996 has been
    calculated at the same effective rate before exceptional items as that
    assumed in the pro forma tax charge for the year ended 30 September 1996
    which was given in the group's listing particulars.

4.  EXCEPTIONAL OPERATING COSTS
 
The exceptional costs in the six month period relate to L7 million of
restructuring costs within the Power segment and costs of L9 million associated
with PacifiCorp's bid.
 
5.  TAXATION
 
The effective rate of tax for the six month period is 132.0% compared with 31.2%
for the six months ended 31 March 1997. The increase is due mainly to the
exceptional windfall tax charge of L112 million. The underlying rate, excluding
the impact of the exceptional restructuring charge, is 26.3%.
 
6.  EARNINGS PER ORDINARY SHARE
 
Earnings per ordinary share are calculated using the number of ordinary shares
in issue excluding those held by The Energy Group Employee Benefit Trust which
has waived its right to dividends on the shares it holds. The number of ordinary
shares used to calculate earnings per share was as follows:

               EASTERN ELECTRICITY ACCEPTS OFFER PRICE PROPOSALS
 
The Energy Group announces that Eastern Electricity, part of Eastern Group,
confirmed today that it has accepted OFFER's supply price review proposals.
 
From April next year Eastern's three million customers can expect to receive an
average reduction in their electricity bills of nearly 12 per cent in real terms
over two years.
 
For a typical customers -- on the standard domestic tariff with an annual bill
of L260 a year -- this represents a reduction in 1998/99 of L23. There will be a
further reduction of L8 in the following year -- giving a total real terms
reduction of L54 over the two years.
 
Including the latest reductions, power prices for a typical Eastern domestic
customer will have fallen by 30 per cent in real terms since 1991.
 
John Devaney, Executive Chairman of Eastern Group, said: "This is excellent news
for customers who will continue to receive an excellent product at a competitive
price. They are now guaranteed price reductions of nearly 12 per cent over the
next two years with no real increase in current standing charges."

RAWHIDE MINE IDLED
DUE TO WEAK MARKET CONDITIONS
 
GILLETTE, Wyo., Nov. 14 -- Rawhide Mine in Wyoming will be idled on April 1,
1998, for an indefinite period due to weak market conditions. Rawhide is
operated by Peabody Holding Company's Powder River Coal Company.
 
     "Although Rawhide's employees have made the mine very productive, we will
not squander the mine's low sulfur reserves by selling its production at today's
spot prices," said Peabody Holding President and Chief Operating Officer Peter
B. Lilly.
 
     Powder River Coal President Larry H. Fox said, "We will consolidate our
business and optimize production at our other mines until market conditions
justify reopening Rawhide. For 1998, contract sales for Rawhide will be shipped
from Powder River Coal's three other mines in Wyoming."
 
     The mine's 154 employees will be offered other jobs at Powder River Coal's
North Antelope, Rochelle and Caballo mines or remain at the mine to continue
reclamation, maintenance or operational activities.

RAWHIDE MINE IDLED -- ADD ONE
 
     "By idling Rawhide, Powder River Coal Company will avoid participation in
the weak spot markets," Fox said. All of the company's 1997 and 1998 scheduled
coal production has been sold. "Market prices have improved somewhat in recent
weeks but the increase is not sufficient to justify selling Rawhide's coal in
the spot market. We expect that Phase Two of the Clean Air Act and further
penetration of the eastern U.S. coal market will increase demand for Powder
River's coal and allow us to reopen Rawhide Mine."
 
     Rawhide Mine, located nine miles north of Gillette, Wyo., shipped 12
million tons of coal in the 12 months ending September 30, 1997. Powder River
Coal Company sold 91.6 million tons during the year. According to U.S. Labor
Department data, Powder River Coal's four mines -- North Antelope, Rawhide,
Rochelle and Caballo -- were the top four mines in the United States in 1996 in
terms of productivity.
 
     Peabody, the world's largest private coal producer, is part of The Energy
Group PLC, a diversified international energy company, which also includes
Eastern, a leading integrated electricity and gas group in Great Britain, and
Citizens Power, one of the top ten power marketers in the United States.
Peabody's coal products fuel more than 9 percent of U.S. electricity generation.

                 EASTERN GROUP AGREES COAL DEAL WITH RJB MINING
 
EASTERN POWER & ENERGY TRADING LTD, PART OF EASTERN GROUP, ANNOUNCED TODAY THAT
IT HAS SUCCESSFULLY CONCLUDED NEGOTIATIONS WITH RJB MINING FOR THE PURCHASE OF 4
MILLION TONNES OF COAL PER ANNUM FOR THE NEXT THREE YEARS, STARTING APRIL 1998.
 
Eastern Group, through its subsidiary Eastern Generation, is Britain's fourth
biggest electricity generator with around 10 per cent of the country's total
generating capacity. It currently owns, operates or has interests in eight power
stations -- a mix of combined-cycle gas turbine and coal-fired stations.
 
The capacity increased by almost 6,000MW in 1996 as a result of leasing
agreements for five coal-fired stations -- Rugeley, Ironbridge, West Burton,
High Marnham and Drakelow.
 
John Devaney, Eastern's Executive Chairman, said: "We are very pleased to have
concluded negotiations with RJB. This contract forms an important part of our
coal portfolio for the next three years."

                 GEARING-UP FOR THE MILLENNIUM -- HOLMER GREEN
 
EASTERN ELECTRICITY, A NATION-WIDE PROVIDER OF ELECTRICITY, IS INVESTING
L250,000 TO REVOLUTIONISE THE ELECTRICITY SUPPLY NETWORK AT HOLMER GREEN IN
BUCKINGHAMSHIRE.
 
A major scheme to refurbish the 11,000 volt overhead lines which transport power
from Amersham and Great Missenden to Holmer Green is currently underway. The
work will be completed by Christmas.
 
The work follows an earlier underground cable laying project which included new
switchgear being strategically installed on both high voltage circuits supplying
Holmer Green. This scheme is leading edge technology and a first for Eastern
Electricity and the UK.
 
The current work will include improving lightning protection, installing vermin
protection and selective undergrounding of high voltage overhead lines in
densely wooded areas. The new technology brings the benefits of greater
flexibility, greater protection and low maintenance.
 
Much of the new equipment can be controlled remotely from Eastern's Central
Control Centre. Once fitted, the system will mean fewer interruptions and
improved restoration times if a fault occurs.
 
By the turn of the century the company will have refurbished or replaced the
majority of its 11,000 volt overhead network of wires -- some 19,700 kilometres
in total and the backbone of the rural network.
 
Eddie Hyams, Managing Director Networks said: "Eastern is looking to the future.
We are half-way through a major programme of investment throughout the region
which serves to reaffirm the company's continuing commitment to reliability and
a quality customer service."
 
Another innovation, a method of working on overhead lines while they are still
live, is now widely used by Eastern Electricity linesmen. Called 'hot-glove'
working it often enables maintenance to be carried out on overhead lines without
interrupting power supplies.
<PAGE>   230
 
New diagnostic techniques are being introduced which will pin-point the optimum
time to schedule maintenance work -- again minimising the need to interrupt
customers electricity supplies.
 
Latest statistics show that the overall reliability of Eastern's network is
continually improving. During 1996/97, for the second year running, the overall
time customers were without electricity was reduced. When faults did occur,
supplies were restored within three hours in 93.1 per cent of cases -- one of
the best performances in the country.

               GEARING-UP FOR THE MILLENNIUM IN -- NEWTON FLOTMAN
 
Eastern Electricity, a nation-wide provider of electricity, is rebuilding the
overhead power network in and around Newton Flotman using a new covered
conductor developed in Finland.
 
It is the first time this type of covered conductor which has been designed to
improve supply reliability in the harshest of environments, has been used on
Eastern Electricity's high voltage network.
 
A total of 54km of overhead lines will be replaced at a cost of L1.5m. The work
will be completed by the Spring.
 
The improved insulating properties of the covering greatly reduces the risk of
damage by clashing conductors, tree branches, windbourne debris and vermin.
 
Eastern Electricity will be rebuilding the existing 11,000 volt overhead lines
in the parishes of Newton Flotman, Swainsthorpe, Shotesham, Stoke Holy Cross,
Poringland, Bracon Ash, Flordon and Saxlingham Nethergate.
 
Region wide, Eastern Electricity is investing L460 million over the five year
period 1995-2000 to revolutionise its electricity network -- already one of the
most reliable in the country.
 
Eddie Hyarns, Managing Director Networks said: "Eastern is looking to the
future. We are half-way through a major programme of investment which serves to
reaffirm the company's continuing commitment to reliability and a quality
customer service."
 
By the turn of the century the company will have renovated or replaced the
majority of its 11,000 volt overhead network of wires -- some 19,700 kilometres
in total and the backbone of the rural network.

                 EASTERN LAUNCHES ELECTRICITY SALES NATION-WIDE
                 AND SLICES L150 OFF GAS AND ELECTRICITY BILLS
 
EASTERN GROUP -- ALREADY A NATION-WIDE SUPPLIER OF ELECTRICITY AND GAS TO
BUSINESSES -- TODAY PLEDGED TO SLICE L150 OR MORE OFF GAS AND ELECTRICITY BILLS
NEXT YEAR FOR MILLIONS OF HOUSEHOLDS PREPARED TO SWITCH SUPPLIERS FOR THE
FIRST-TIME.
 
The company aims to supply up to six million homes nation-wide by the turn of
the century -- building on its existing three million electricity customers and
450,000 households that have now switched to Eastern Natural Gas as gas
competition is phased-in across Britain.
 
Eastern is offering 20% or 24.6% off current British Gas standard
prices -- saving at least L100 a year on a L500 bill. Households switching to
Eastern for electricity will receive L30 cash-back plus typical savings of
between L20 and L50 per year. Either deal is available separately.
 
John Devaney, Executive Chairman, Eastern Group, said: "We are the leading and
fastest growing supplier and aim to be the number one choice for customers
through innovation, competitive pricing and the quality of our service."
 
This major initiative, under the name Eastern Electricity & Natural Gas, is
already underway and has secured thousands of new electricity customers ahead of
the start of competition.
 
The early targets include Canterbury, Hull and Chester postcode areas which,
along with Norwich within Eastern's own region, are the first areas to be opened
up to electricity competition in 1998.
 
Customers can find out more about the savings by calling free-phone 0800 7 313
313. Switching suppliers is simple. Eastern will use existing meters, pipes and
cables and will bill customers directly.

Eastern Group is the leading nation-wide supplier of electricity and natural gas
in the industrial and commercial markets which have already opened to
competition. The company has 13% of the 100kW-plus electricity market and 11% of
the competitive business gas market.
 
Eastern's existing three million domestic customers in north London and the
eastern counties will have seen, by April 1998, average electricity prices fall
by around 30% in real terms since 1991.

Notes to editors
 
- - A household currently spending L500 a year on gas and paying quarterly by cash
  or cheque with British Gas would save around 20% (L100) by switching to
  Eastern -- or up to 24.6% by switching to direct debit.
 
- - The customer will receive a one-off L30 cash-back for switching to Eastern
  from their local electricity company. Electricity tariffs vary from region to

PRESS RELEASE                                  [THE ENERGY GROUP PLC letterhead]
 
December 19, 1997
 
THE PRESIDENT OF THE BOARD OF TRADE GIVES APPROVAL
FOR PACIFICORP'S PROPOSED OFFER FOR THE ENERGY
GROUP PLC
 
The Energy Group welcomes the announcement today by the President of the Board
of Trade approving the proposed offer for The Energy Group by PacifiCorp.
 
Commenting on the announcement, Derek Bonham, Chairman of The Energy Group said:
 
"We note that approval has been received based on the original undertakings
provided by PacifiCorp. However, approvals from the Federal Trade Commission and
the Federal Energy Regulatory Commission in the USA are still awaited and, until
all the regulatory hurdles have been cleared, we do not intend making any
further comment or announcements. It will be recalled that the offer made by
PacifiCorp in June 1997 lapsed on its referral to the Monopolies and Mergers
Commission.
 
We continue to believe, however, that the combination of The Energy Group and
PacifiCorp would create a premier global energy company. The Energy Group has an
exciting future and our core businesses continue to perform strongly. Our
success in winning significant numbers of new gas customers demonstrates our
ability to compete in the UK. We intend to be a vigorous competitor in the
electricity markets as they open up.
 
                                                                      Cont . . .

The combination of Peabody and Citizens Power is already providing the Group

FOR IMMEDIATE RELEASE
Dec. 22, 1997
 
PEABODY GROUP, MONTANA POWER
ANNOUNCE ROCKY BUTTE ACQUISITION
 
GILLETTE, Wyo., Dec. 22 -- Subsidiaries of the Peabody Group and The Montana
Power Company said today that Caballo Coal Company has acquired from Horizon
Coal Services Inc. 280 million tons of recoverable reserves, known as Rocky
Butte, adjacent to the Caballo Mine south of Gillette.
 
     Caballo Coal Company is a subsidiary of the Peabody Group's Powder River
Coal Company, headquartered in Gillette. Horizon Coal Services is a subsidiary
of Butte-based Montana Power, a broadly diversified energy and
telecommunications services company. Terms of the agreement were not disclosed.
 
     Powder River Coal President Larry H. Fox said, "This is an excellent
addition of a high quality coal reserve to our portfolio. In the short term,
this strategic acquisition will maximize our current coal recovery at Caballo,
while extending the life of the mine by about 10 years. More importantly,
however, the acquisition of the Rocky Butte reserves demonstrates our long-term
commitment to coal development in the Powder River Basin."
 
     Dick Cromer, executive vice president of Montana Power's Energy Supply
Division, said the transaction is good for both companies.
 
     "While the Rocky Butte reserves are no longer a strategic asset for us
because of corporate decisions to focus on other Montana Power energy and
telecommunications business lines, they do represent a logical expansion to an
existing operation in the Power River Basin," he said. "I'm pleased we were able
to reach this agreement with Peabody, a company we consider to be a premiere
coal operation."

ROCKY BUTTE -- ADD ONE
 
Caballo Mine, located 15 miles south of Gillette, shipped 20.8 million tons of
coal in the 12 months ending September 30, 1997. Powder River Coal Company sold
91.6 million tons during the year. According to U.S. Labor Department data,
Caballo Mine was the nation's fourth most productive mine in 1996.
 
     Peabody, the world's largest private coal producer, is part of The Energy
Group PLC, a diversified international energy company, which also includes
Eastern, a leading integrated electricity and gas group in Great Britain, and
Citizens Power, one of the top ten power marketers in the United States.
Peabody's coal products fuel more than 9 percent of U.S. electricity generation.

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 to predict all of such factors; nor can 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 be
assessed.
 
FINANCIAL CONDITION
 
  Mergers and Acquisitions
 
     Certain comparisons in this Annual Report have been affected by the August
1997 acquisition of ENSERCH Corporation (ENSERCH) and the November 1997
acquisition of Lufkin-Conroe Communications Co. (LCC) by the Company and 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 each acquired company are included only for the periods
subsequent to acquisition. (See Note 1 to Consolidated Financial Statements.)
 
     On August 5, 1997, the merger transactions (Merger) between the former
Texas Utilities Company, now known as Texas Energy Industries Inc. (TEI), and
ENSERCH were completed. At the effective time of the Merger: (i) the former
Texas Utilities Company changed its name to TEI, (ii) TEI and ENSERCH merged
with wholly-owned subsidiaries of TUC Holding Company, which, as a result, owned
all the common stock of TEI and of ENSERCH, (iii) TUC Holding Company changed
its name to Texas Utilities Company (now the Company), (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.
 
                                       V-4
<PAGE>   250
 
     In the Merger, approximately 15. 9 million shares of TUC common stock were
issued to former holders of ENSERCH common stock. The value assigned to the TUC
shares issued and costs incurred in connection with the acquisition of ENSERCH
aggregated $579 million. At the date of the Merger, ENSERCH had debt and
preferred stock outstanding of approximately $1.3 billion.
 
     Businesses and subsidiaries acquired in the Merger were Lone Star Gas
Company (Lone Star Gas), a gas distribution company in Texas, Lone Star Pipeline
Company (Lone Star Pipeline) and subsidiaries engaged in natural gas processing,
natural gas marketing, independent power production and international gas
distribution systems development.
 
     On November 21, 1997, the Company acquired LCC. Approximately 8.7 million
shares of TUC common stock were issued to LCC stockholders in a stock-for-stock
exchange. The value assigned to the TUC shares issued and costs incurred in
connection with the acquisition of LCC aggregated $319 million. At the date of
the acquisition, LCC had debt outstanding of approximately $31 million.
 
     The acquisitions of ENSERCH, LCC and Eastern Energy were accounted for as
purchase business combinations. The assets and liabilities of the acquired
companies at the acquisition dates were adjusted to their estimated fair values.
The excess of the purchase price paid by the Company over the estimated fair
value of net assets acquired and liabilities assumed was recorded as goodwill
and is being amortized over 40 years. The process of determining the fair value
of assets and liabilities of ENSERCH and LCC as of the date of acquisition is
continuing, and the final result awaits primarily the resolution of income tax
and other contingencies and finalization of some preliminary estimates.
 
     For financial reporting purposes, the Company is being treated as the
successor to TEI. Unless otherwise specified, all references to the Company
which relate to a period prior to August 5, 1997, shall be deemed to be
references to TEI.
 
     The Company continues to seek potential investment opportunities from time
to time when it concludes that such investments are consistent with its business
strategies and are likely to enhance the long-term return to its shareholders.
In January 1998, the Company announced that it had approached the Energy Group
plc (TEG) in connection with its possible interest in acquiring TEG. TEG is a
diversified international energy group. Discussions between the Company and TEG
are continuing and may or may not lead to an offer being made by the Company.
Likewise, the timing, amount and funding of any specific new business investment
opportunities are presently undetermined.
 
CAPITAL EXPENDITURES
 
     The primary capital expenditures of the Company and all of its
majority-owned subsidiaries (System Companies) in 1997 and as estimated for 1998
through 2000 are as follows:

     In 1997, the Company bought ENSERCH for $579 million and LCC for $319
million primarily through the issuance of common stock.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     For 1997, the System Companies generated cash from operations sufficient to
meet operating needs and debt service requirements, pay dividends on capital
stock, pay distributions on preferred securities of trusts and finance capital
expenditures. Factors affecting the continued ability of Texas Utilities
Electric Company (TU Electric), the Company's primary subsidiary, to fund its
capital requirements from operations include responsive regulatory practices
allowing recovery of capital investment through adequate depreciation rates,
recovery of the cost of fuel and purchased power and the opportunity to earn
competitive rates of return required in the capital markets.
 
     External funds of a permanent or long-term nature are obtained through the
issuance of common and preferred stock, preferred securities and long-term debt
by the System Companies. The capitalization ratios of the Company and its
subsidiaries at December 31, 1997, consisted of approximately 52% long-term
debt, 5% TU Electric obligated, mandatorily redeemable, preferred securities of
subsidiary trusts holding solely debentures of TU Electric, 2% preferred stock
and 41% common stock equity.
 
     Proceeds from financings by System Companies in 1997 were used primarily
for the early redemption or reacquisition of debt and preferred stock. The
financings consisted of:

     During 1997, the Company purchased and retired 4,015,000 shares of its
common stock at a cost of $148.8 million. In addition, long-term debt and
preferred stock of subsidiary companies totaling $2.1 billion was retired. Early
redemptions of long-term debt and preferred stock may occur from time to time in
amounts presently undetermined. (See Notes 6 and 8 to Consolidated Financial
Statements.)
 
     At December 31, 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 million 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 million 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 million outstanding at any one time. ENSERCH's
borrowings under both facilities are limited to an aggregate of up to $650
million 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 December 31, 1997, from banks or other lenders, was $2,150
million.
 
     In addition, certain non-U.S. subsidiaries have revolving credit agreements
aggregating approximately $95 million, of which $61 million was outstanding at
December 31, 1997. These revolving credit agreements expire at various dates
through 2000.
 
                                       V-6
<PAGE>   252
 
     In January 1998, the Company issued $200 million of 6.375% Series C Senior
Notes due 2008, and ENSERCH issued $125 million of 6 1/4% Series A Notes due
2003 and $125 million of Remarketed Reset Notes due 2008 with a variable
interest rate (5.82% at date of issuance). Net proceeds from these borrowings
were used to refinance or redeem like amounts of higher rate debt and preferred
stock.
 
     The System Companies may issue additional debt and equity securities as
needed, including the possible future sale: (i) by TU Electric of up to $148.9
million 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 $250 million 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.
 
QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK
 
     The Company's market risk exposure is primarily a result of changes in
interest rates and commodity price exposures. Derivative instruments including
options, swaps, futures and other contractual commitments are used to reduce and
manage a portion of those risks. With the exception of the marketing activities
of a subsidiary, Enserch Energy Services, Inc. (EES), the Company's
participation in derivative transactions are designated for hedging purposes;
derivative instruments are not held or issued for trading purposes.
 
     Credit Risk -- Credit risk relates to the risk of loss that the Company
would incur as a result of nonperformance by counterparties to their respective
derivative instruments. The Company maintains credit policies with regard to its
counterparties that management believes significantly minimize overall credit
risk. The Company does not obtain collateral to support the agreements but
monitors the financial viability of counterparties and believes its credit risk
is minimal on these transactions. The Company believes the risk of
nonperformance by counterparties is minimal.
 
                                       V-7
<PAGE>   253
 
     Interest Rate Market Risk -- The table below provides information
concerning the Company's financial instruments as of December 31, 1997 that are
sensitive to changes in interest rates, which include debt obligations and
interest rate swaps. For debt obligations, the table presents principal cash
flows and related weighted average interest rates by expected maturity dates.
The Company has entered into interest rate swaps under which it has agreed to
exchange the difference between fixed-rate and variable-rate interest amounts
calculated with reference to the specified notional principal amounts. The
contracts require settlement of net interest receivable or payable at specified
intervals (primarily semi-annually) which generally coincide with the dates on
which interest is payable on the underlying debt. When differences exist between
the swap settlement dates and the dates on which interest is payable on the
underlying debt, the gap exposure, or basis risk, is managed by means of forward
rate agreements. These forward rate agreements are not expected to have a
material effect on the Company's financial position, results of operations or
cash flows. For interest rate swaps, the table presents notional amounts and
weighted average interest rates by expected (contractual) maturity dates.
Weighted average variable rates are based on rates in effect at the reporting
date.

     Energy Marketing Market Risk -- 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 options,
swaps, 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 December 31, 1997, natural gas marketing operations
had net commitments to sell approximately 50.6 billion cubic feet (Bcf) of
natural gas through the year 2003 with offsetting net financial positions to
purchase approximately 61.3 Bcf.
 
                                       V-8
<PAGE>   254
 
     For purposes of new SEC disclosure requirements, EES has performed a
sensitivity analysis to estimate its exposure to market risk of its commodity
and related financial commitments. The exposure for fixed price natural gas
purchase and sale commitments, and derivative financial instruments, including
options, swaps, futures and other contractual commitments, is based on a
methodology that uses a five-day holding period and a 95% confidence level. EES
uses market-implied volatilities to determine its exposure to volatility risk.
Market risk is estimated as the potential loss in fair value resulting from at
least a 15% change in market factors which may differ from actual results. Using
15%, the most adverse change in fair value at December 31, 1997 as a result of
this analysis, was a reduction of $1.1 million. For additional information
regarding derivative instruments, see Note 9 to Consolidated Financial
Statements.
 
     Nuclear Decommissioning and Disposal of Spent Fuel Trust -- TU Electric has
established an external trust to provide for nuclear decommissioning and
disposal of spent fuel. The trust is invested in marketable fixed income debt
and equity securities. At December 31, 1997, the current market value of the
debt and equity securities was $85.9 million and $74.1 million, respectively. A
hypothetical 10% increase in interest rates and 10% decrease in equity prices
would result in a $10.8 million reduction in the fair value of the trust assets.
However, adjustments to market value result in a corresponding adjustment to
related liability accounts based on current regulatory treatment.
 
REGULATION AND RATES
 
     Under the current regulatory environment, certain System Companies are
subject to the provisions of Statement of Financial Accounting Standards (SFAS)
No. 71, "Accounting for the Effects of Certain Types of Regulation" (SFAS 71).
This statement applies to utilities that have cost-based rates established by a
regulator and charged to and collected from customers. In accordance with this
statement, these companies may defer the recognition of certain costs
(regulatory assets) and certain obligations (regulatory liabilities) that, as a
result of the ratemaking process, have probable corresponding increases or
decreases in future revenues. Future significant changes in regulation or
competition could affect these companies' ability to meet the criteria for
continued application of SFAS 71 and may affect these companies' ability to
recover such regulatory assets from, or refund such regulatory liabilities to,
customers. These regulatory assets and liabilities are being amortized over
various periods (5 to 40 years). The amortization is currently, or is expected
to be, included in rates. In the event all or a portion of these companies'
operations fail to meet the criteria for application of SFAS 71, these companies
would be required to write-off all or a portion of their regulatory assets and
liabilities. Should significant changes in regulation or competition occur, the
affected System Companies would be required to assess the recoverability of
certain assets, including plant and regulatory assets, and, if impaired, to
write down the assets to reflect their fair market value. (See Note 2 to
Consolidated Financial Statements.) The System Companies cannot predict the
timing or extent of changes in the business environment that may require the
discontinuation of SFAS 71 application.
 
     Although TU Electric cannot predict future regulatory or legislative
actions or any changes in economic and securities market conditions, no changes
are expected in trends or commitments, other than those discussed in this Annual
Report, that might significantly alter its basic financial position, results of
operation or cash flows. (See Note 15 to Consolidated Financial Statements.)
 
     DOCKET 9300 -- The PUC's final order (Order) in connection with TU
Electric's January 1990 rate increase request (Docket 9300) was reviewed by the
250th Judicial District Court of Travis County, Texas, (District Court) and
thereafter was appealed to the Court of Appeals for the Third District of Texas
and to the Supreme Court of Texas (Supreme Court). As a result of such review
and appeals, an aggregate of $909 million of disallowances with respect to TU
Electric's reacquisitions of minority owners' interests in Comanche Peak, which
had previously been recorded as a charge to the Company's earnings, has been
remanded to the District Court with instructions that it be remanded to the PUC
for reconsideration on the basis of a prudent investment standard. On remand,
the PUC would also be required to reevaluate the appropriate level of TU
Electric's construction work in progress included in rate base in light of its
financial condition at the time of the initial hearing. In January 1997, the
Supreme Court denied a motion for rehearing on the Comanche Peak minority owners
issue filed by the original complainants. TU Electric cannot predict the outcome
of the reconsideration of the Order on remand by the PUC.
                                       V-9
<PAGE>   255
 
     In its decision, the Supreme Court also affirmed the previous $472 million
prudence disallowance related to Comanche Peak. Since the Company has previously
recorded a charge to earnings for this prudence disallowance, the Supreme
Court's decision did not have an effect on the Company's current financial
position, results of operation or cash flows.
 
     DOCKET 11735 -- In July 1994, TU Electric filed a petition in the 200th
Judicial District Court of Travis County, Texas to seek judicial review of the
final order of the PUC granting a $449 million, or 9.0%, rate increase in
connection with TU Electric's January 1993 rate increase request of $760
million, or 15.3% (Docket 11735). Other parties to the PUC proceedings also
filed appeals with respect to various portions of the order.
 
     DOCKETS 15638 AND 15840 -- In May 1996, TU Electric filed with the PUC its
transmission cost information and tariffs for open-access wholesale transmission
service (Docket 15638) in accordance with PUC rules adopted in February 1996.
These tariffs also provide for generation-related ancillary services necessary
to support wholesale transactions. In August 1997, the PUC approved final
tariffs for TU Electric and implemented rates for other transmission providers
within the Electric Reliability Council of Texas (ERCOT) (Docket 15840). Under
rates implemented by the PUC, TU Electric's payments for transmission service
will exceed its revenues for providing transmission service. The PUC has adopted
a rate-moderation plan that will minimize the impact of the new pricing
mechanism for the first three years the rules are in effect. As such, the
current maximum impact on the Company for 1998 is an $8.52 million deficit,
which, in the opinion of the Company, is not expected to have a material effect
on its financial position, results of operation or cash flows.
 
     DOCKET 17250 -- In late 1996, as part of its regular earnings monitoring
process, the PUC staff advised the PUC, after reviewing the 1995 Electric
Investor-Owned Utilities Earnings Report of TU Electric, 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 longer-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 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.
 
     DOCKET 18490 -- On December 17, 1997, TU Electric, together with the PUC
General Counsel, the Office of Public Utility Counsel and various other parties
interested in TU Electric's rates and services, filed with the PUC a stipulation
and joint application which, if granted, would among other things: (i) result in
permanent retail base rate credits beginning January 1, 1998, of 4% for
residential customers, 2% for general service secondary customers and 1% for all
other retail customers, (ii) result in additional permanent retail base rate
credits beginning January 1, 1999, of 1.4% for residential customers, (iii)
impose a 11.35% cap on TU Electric's rate of return on equity during 1998 and
1999, with any sums earned above that cap being applied as additional nuclear
production depreciation, (iv) allow TU Electric to record depreciation
applicable to transmission and distribution assets in 1998 and 1999 as
additional depreciation of nuclear production assets, (v) establish an updated
cost of service study that includes interruptible customers as customer classes,
(vi) result in the permanent dismissal of pending appeals of prior PUC orders
including Docket No. 11735, if all other parties that have filed appeals of
those dockets also dismiss their appeals, (vii) result in the stay of any
proceedings in the removal of Docket 9300 prior to January 1, 2000, and (viii)
result in all gains from off-system sales of electricity in excess of the amount
included in base rates being flowed to customers through the fuel factor.
 
     The PUC has until March 31, 1998 to approve or reject the stipulation and
joint application. Otherwise, TU Electric may terminate the base rate reductions
and all other aspects of the proposal upon giving two weeks notice to the PUC.

     Fuel Reconciliation Proceedings -- 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 $81 million of eligible fuel related costs (including
interest of $12 million) 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 has appealed the PUC's order.
 
     Fuel Cost Recovery Rule -- TU Electric in July 1997, petitioned the PUC for
and received interim approval to refund 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.
 
     Lone Star Gas and Lone Star Pipeline Rates -- In October 1996, Lone Star
Pipeline filed a request with the RRC to increase the rate it charges Lone Star
Gas 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 previously in effect were set by
the RRC in 1982. In September 1997, the RRC issued an order reducing the charges
by Lone Star Pipeline to Lone Star Gas for storage and transportation services.
In that order, the RRC did authorize separate charges for the Lone Star Pipeline
storage and transportation services, a separate charge by Lone Star Gas for the
cost of aggregating gas supplies, and a continuation of the 100% flow through of
purchased gas expense. The RRC also imposed some new criteria for affiliate gas
purchases and a new reconciliation procedure that will require a review of
purchased gas expenses every three years. The RRC order has become final, but is
being appealed by several parties including Lone Star Pipeline and Lone Star
Gas. The rates authorized by the order became effective on December 1, 1997, and
will result in an annual margin reduction of approximately $8.2 million.
 
     On August 20, 1996, the RRC ordered a general inquiry into the rates and
services of Lone Star Gas, most notably a review of Lone Star Gas' historic gas
cost and gas acquisition practices since the last rate setting. The inquiry
docket has been separated into different phases. Two of the phases, conversion
to the NARUC account numbering system and unbundling, have been dismissed by the
RRC, and one other phase, rate case expense, is pending RRC action on the basis
of a stipulation of all parties. In the phase dealing with historic gas cost and
gas acquisition practices, Lone Star Gas and Lone Star Pipeline have filed a
motion for summary disposition stating that any retroactive rate action would be
inappropriate and unlawful. Settlement discussions with intervenor cities are
ongoing. If the motion for summary disposition is denied, a hearing has been
scheduled to begin in August 1998. A number of management and transportation
related issues have been placed in a separate phase which still has an undefined
scope and is being held in abeyance pending the resolution of the phase dealing
with gas costs. Management believes that gas costs were prudently incurred and
were properly accounted for and recovered through the gas cost recovery
mechanism previously approved by the RRC. At this time, management is unable to
determine the ultimate outcome of the inquiry.
 
COMPETITION
 
     The National Energy Policy Act of 1992 (Energy Policy Act) addresses a wide
range of energy issues and is intended to increase competition in electric
generation and broaden access to electric transmission systems. In addition, the
Public Utility Regulatory Act of 1995, as amended (PURA), impacts the PUC and
its regulatory practices and encourages increased competition in some aspects of
the electric utility industry in Texas. Although the Company is unable to
predict the ultimate impact of the Energy Policy Act, PURA and
 
                                      V-11
<PAGE>   257
 
any related regulations or legislation on the System Companies' operations, it
believes that such actions are consistent with the trend toward increased
competition in the energy industry.
 
     In order to remain competitive, the System Companies 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.
 
     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 in 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.
 
     Federal legislation such as the Public Utility Regulatory Policy Act of
1978 (PURPA) and, more recently, the Energy Policy Act, as well as initiatives
in various states, encourage wholesale competition among electric utility and
non-utility power producers. Together with increasing customer demand for lower-
priced electricity and other energy services, these measures have accelerated
the industry's movement toward a more competitive pricing and cost structure.
Competition in the electric utility industry was also addressed in the 1995
session of the Texas legislature. PURA was amended to encourage greater
wholesale competition and flexible retail pricing. PURA amendments also require
the PUC to report to the legislature, during each legislative session, on
competition in electric markets. Accordingly, PUC reports were submitted to the
Texas legislature in January 1997, recommending that the legislature continue
the process of expanding competition in the Texas electricity markets, leading
to expanded retail competition, and authorize the PUC to take numerous steps
toward that goal. The PUC further recommended that full competition not occur
prior to the year 2000 in order to provide an environment through which both
retail customers and utilities in Texas move more smoothly to achieve the
perceived benefits of competition. The PUC is seeking guidance from the
legislature and authority to address the issue of stranded cost recovery. The
PUC's estimate for TU Electric's potentially stranded retail costs ranged from a
projected excess of net book value over market value of $7.7 billion to a
projected excess of market value over net book value of $2.1 billion.
Legislation that would have authorized retail competition was not enacted by the
1997 Texas legislature.
 
     While the Company anticipates legislation being enacted during the 1999
session of the Texas legislature to authorize competition in the retail market,
they cannot predict the ultimate outcome of the ongoing efforts that are taking
place to restructure the electric utility industry or whether such outcome will
have a material effect on their financial position, results of operation or cash
flows.
 
RESULTS OF OPERATION
 
     For the year ended December 31, 1997, net income for the Company decreased
approximately 12% from the prior period. Results for 1997 were reduced by the
recognition of TU Electric's $80.0 million Rate Settlement refund in July 1997,
the August 1997 $81.1 million Fuel Disallowance (including interest) and a
charge of $10.1 million from the sale of sulfur dioxide allowances previously
recognized. After revenue-related and income taxes, these settlements reduced
income by $103.4 million. Excluding these items, 1997 net income increased
slightly over the 1996 period. For the year ended December 31, 1996, net income
increased approximately 14% over the comparable 1995 period, excluding the
after-tax effect of recording a September 1995 impairment of several
non-performing assets. Such impairment, on an after-tax basis, amounted to $802
million. (See Note 14 to Consolidated Financial Statements.)
 
     TU Electric continued to experience core revenue and sales volume growth in
excess of 3% due to increases in both number of customers and usage. Warmer than
normal summer weather contributed to 1996 results, while summer weather was
normal in 1995 and 1997.
 
                                      V-12
<PAGE>   258
 
     Operating revenues increased approximately 21% and 16% for the years ended
December 31, 1997 and 1996, respectively. In 1997, the increase in operating
revenues was due primarily to the inclusion of ENSERCH revenues ($1,278.0
million) for the period following the Merger and to TU Electric's transmission
service revenues ($113.8 million) from implementing the PUC's Open Access
Transmission Rule effective January 1, 1997. LCC's revenues after acquisition
were $11.9 million. In 1996, the increase was due primarily to a full year of
Eastern Energy's revenues ($474 million).
 
     Base rate electricity revenues (including unbilled sales) decreased
slightly from 1996 as a result of the Rate Settlement refund mentioned above,
while electric energy sales in megawatt hours (including unbilled sales)
increased approximately 2% and 11% for 1997 and 1996, respectively. Fuel revenue
increased in 1997 and 1996 due primarily to increases in fuel costs driven by
increased energy sales and spot market gas prices, partially offset, in 1997, by
the Fuel Disallowance.
 
     Fuel and purchased power expense increased approximately 4% and 30% for
1997 and 1996, respectively. The increases were primarily due to increased
energy sales and increased spot market gas prices and in 1996 included 13.1%
attributable to Eastern Energy for a full year. (See Consolidated Operating
Statistics.) Gas purchased for resale represents the cost of gas ultimately sold
to ENSERCH gas customers, which is recovered in rates.
 
     Total operating expenses, excluding fuel and purchased power and gas
purchased for resale, increased approximately 15% for 1997 and 9% for 1996
(including 8.6% in 1997 attributable to ENSERCH companies since acquisition and
5.7% in 1996 attributable to Eastern Energy). Operation and maintenance expense
increased in 1997 as result of recording third party transmission expenses in
accordance with the Public Utility Commission's Open Access Transmission Rule,
partially offset by decreased employee benefit expenses. The 1996 increase is
due primarily to increases in employee benefit expenses and payroll expenses.
Taxes other than income increased in 1997 due primarily to the effect of ENSERCH
and LCC amounts subsequent to acquisition. Taxes other than income decreased in
1996 as a result of a reduction in TU Electric's ad valorem tax obligation due
primarily to a property tax rate reduction, partially offset by an increase in
state and local gross receipts tax.
 
     The change in other income (deductions) -- net in 1997 was primarily due to
losses from an interest in a telecommunications partnership. Amounts for 1996
were lower than the previous year due primarily to increased non-utility
property expenses and decreased allowance for equity funds used during
construction, partially offset by gains on the disposition of certain
properties.
 
     Interest expense and distributions on preferred securities and preferred
stock of subsidiaries totaled $860.6 million in 1997, $884.3 million in 1996 and
$792.9 million in 1995. The Company's capital restructuring and debt reduction
programs have favorably affected the comparisons. Year-to-year comparisons are
also affected by the debt incurred or assumed in connection with the 1997
acquisitions of ENSERCH and LCC and the December 1995 acquisition of Eastern
Energy. Interest expense in 1996 included an interest payment related to a
settlement with the Internal Revenue Service, and 1997 interest expense included
a charge related to the settlement on over-recovered fuel. Allowance for funds
used during construction (AFUDC) decreased $2.4 million from 1996 to 1997 and
$4.1 million from 1995 to 1996.
 
     The change in income tax expense (benefit) from 1995 to 1996 was due
primarily to the effects of the recording of the September 1995 asset
impairment. (See Note 10 to Consolidated Financial Statements for a
reconciliation of income taxes (benefit) computed at the statutory rate to
provision for income taxes (benefit)).
 
CHANGES IN ACCOUNTING STANDARDS
 
     SFAS 130, "Reporting Comprehensive Income," will become effective in 1998.
This statement requires companies to report and display comprehensive income and
its components (revenues, expenses, gains and losses). Comprehensive income
includes all changes in equity during a period except those resulting from
investments by owners and distributions to owners.
 
                                      V-13
<PAGE>   259
 
     SFAS 131, "Disclosures About Segments of an Enterprise and Related
Information," will become effective in 1998. This statement establishes
standards for defining and reporting business segments. The Company is currently
determining its reportable segments.
 
     The adoption of SFAS 130 and SFAS 131 will not affect financial position,
results of operations or cash flows.
 
YEAR 2000 ISSUES
 
     Many existing computer programs use only two digits to identify a year in
the date field. These programs were designed and developed without considering
the impact of the upcoming change in the century. If not corrected, many
computer applications could fail or produce erroneous data by or at the Year
2000. The Year 2000 issues affect virtually all companies and organizations.
 
     The Company began its Year 2000 initiative in 1996 by addressing
mainframe-based application systems. In early 1997, an infrastructure project to
address information technology (IT) related equipment and systems software was
begun. In late 1997, a corporate-wide project to address Year 2000 issues
related to embedded systems such as process controls for energy production and
delivery and client-developed applications was begun. Most of the ENSERCH
mainframe applications, infrastructure, embedded systems and client-developed
applications that will not be migrated to existing or planned Company systems
have been incorporated into these projects. These projects extend beyond the
Company's organization in an effort to also work with key vendors, service
suppliers and others so that the Company can appropriately prepare for Year
2000.
 
     The remediation and replacement work on the majority of IT application
systems and infrastructure are expected to be completed by the end of 1998. Much
of the work on the corporate-wide Year 2000 project is expected to be completed
by the end of 1998, although the project will extend into 1999. Based on present
assessments of the IT and infrastructure projects, a cost of $11.25 million was
estimated. These costs are being expensed as incurred over the four-year period
(1996 through 1999) covered by the projects. Assessment of the cost of the
corporate-wide Year 2000 project is in the early stages.
 
     Eastern Energy initiated a Year 2000 project in the third quarter of 1997.
The estimated cost of that project is $1.8 million, with completion anticipated
in early 1999. The cost to either modify or replace LCC application systems
affected by Year 2000 is estimated to be $1.5 million, with completion
anticipated in 1999. The effect on LCC's embedded systems is still being
assessed.

                    TEXAS UTILITIES COMPANY AND SUBSIDIARIES
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1  BUSINESS, MERGERS AND ACQUISITIONS
 
     Texas Utilities Company (TUC, or the Company) is a holding company which
owns all of the outstanding common stock of Texas Energy Industries Inc. (TEI)
and ENSERCH Corporation (ENSERCH). TEI is a holding company; the assets of its
primary subsidiary, Texas Utilities Electric Company (TU Electric), and the
Company's other electric utility businesses represent in excess of 85% of the
total assets and in excess of 75% of the total revenues of the Company. TU
Electric is engaged in the generation, purchase, transmission, distribution and
sale of electric energy wholly within Texas. Two other subsidiaries of TEI are
engaged directly or indirectly in public utility operations: Southwestern
Electric Service Company (SESCO) and Texas Utilities Australia Pty. Ltd. (TU
Australia), which in December 1995 acquired the common stock of Eastern Energy
Limited (Eastern Energy), one of five electricity distribution companies
operating in Victoria, Australia. Neither SESCO nor Eastern Energy generate
electric energy. TEI has other wholly-owned service subsidiaries, which support
the operations of the Company and its operating subsidiaries. For 1997, none of
the Company's other businesses are significant individually or in the aggregate
and, accordingly, do not require separate segment disclosure under existing
accounting standards. The Company is currently determining its reportable
segments under Statements of Financial Accounting Standards (SFAS) No. 131,
which becomes effective in 1998.
 
     On August 5, 1997, the merger transactions (Merger) between the former
Texas Utilities Company, now known as TEI and ENSERCH were completed. At the
effective time of the Merger: (i) the former Texas Utilities Company changed its
name to TEI, (ii) TEI and ENSERCH merged with wholly-owned subsidiaries of TUC
Holding Company, which, as a result, owned all the common stock of TEI and of
ENSERCH, (iii) TUC Holding Company changed its name to Texas Utilities Company
(now the Company), (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), a gas distribution company in Texas, serving over 1.3
million customers and providing service through over 23,800 miles of
distribution mains; Lone Star Pipeline Company (Lone Star Pipeline), which has
approximately 7,600 miles of gathering and transmission pipeline in Texas; and
subsidiaries engaged in natural gas processing, natural gas marketing,
independent power production and international gas distribution systems
development.
 
     In the Merger, approximately 15. 9 million shares of TUC common stock were
issued to former holders of ENSERCH common stock. The value assigned to the TUC
shares issued and costs incurred in connection with the acquisition of ENSERCH
aggregated $579 million. At the date of the Merger, ENSERCH had debt and
preferred stock outstanding of approximately $1.3 billion. Effective with the
Merger, under terms specified in the Merger agreement, outstanding options for
ENSERCH common stock were exchanged for options for 532,913 shares of the
Company's common stock exercisable at prices ranging from $7.03 to $37.71 per
share, and ENSERCH was precluded from awarding further options. The estimated
fair value of these options of $3,214,000 was accounted for as a part of the
cost of the acquisition. At December 31, 1997, 402,966 of these options remained
outstanding and exercisable.
 
     On November 21, 1997, the Company acquired Lufkin-Conroe Communications Co.
(LCC). Approximately 8.7 million shares of TUC common stock were issued to LCC
stock holders in a stock-for-stock exchange. The value assigned to the TUC
shares issued and costs incurred in connection with the acquisition of LCC
aggregated $319 million. At the date of the acquisition, LCC had debt
outstanding of approximately $31 million. 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 that serves approximately 100,000 access
lines in the Alto, Conroe and Lufkin areas of
                                      V-20

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
primary focus on business customers.
 
     The acquisitions of ENSERCH, LCC and Eastern Energy were accounted for as
purchase business combinations. The assets and liabilities of the acquired
companies at the acquisition dates were adjusted to their estimated fair values.
The excess of the purchase price paid by the Company over the estimated fair
value of net assets acquired and liabilities assumed was recorded as goodwill
and is being amortized over 40 years. The process of determining the fair value
of assets and liabilities of ENSERCH and LCC as of the date of acquisition is
continuing, and the final result awaits primarily the resolution of income tax
and other contingencies and finalization of some preliminary estimates. The
results of operations of ENSERCH, LCC and Eastern Energy, are reflected in the
consolidated financial statements of the Company from the respective dates of
their acquisition.
 
     The Company continues to seek potential investment opportunities from time
to time when it concludes that such investments are consistent with its business
strategies and are likely to enhance the long-term return to its shareholders.
In January 1998, the Company announced that it had approached the Energy Group
plc (TEG) in connection with its possible interest in acquiring TEG. TEG is a
diversified international energy group. Discussions between the Company and TEG
are continuing and may or may not lead to an offer being made by the Company.
Likewise, the timing, amount and funding of any specific new business investment
opportunities are presently undetermined.
 
     Following is a summary of unaudited pro forma results of operations
assuming the ENSERCH and LCC acquisitions had occurred at the beginning of the
periods presented:

2  SIGNIFICANT ACCOUNTING POLICIES
 
     Consolidation -- The consolidated financial statements include the accounts
of the Company and all of its majority-owned subsidiaries (System Companies).
Prior to August 5, 1997, the date of the Merger, the Company did not have any
assets or operations. Pursuant to the Merger, the Company became the parent of
each of TEI and ENSERCH. For financial reporting purposes, the Company is
treated as the successor to TEI. Unless otherwise specified, all references to
the Company for periods prior to August 5, 1997, are deemed to be references to
TEI since the merger of the Company and TEI is the combination of entities under
common control. The Company's financial statements have been restated in a
manner similar to pooling of interests accounting. Since the acquisitions of
ENSERCH, LCC and Eastern Energy were purchase business combinations, no
financial and other information for those companies are presented for periods
prior to their dates of acquisition.
 
     All significant intercompany items and transactions have been eliminated in
consolidation. Investments in significant unconsolidated affiliates are
accounted for by the equity method. Certain previously reported amounts have
been reclassified to conform to current classifications.
 
                                      V-21
<PAGE>   267
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     Use of Estimates -- The preparation of the Company's 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 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 year.
 
     System of Accounts -- The accounting records of TU Electric and SESCO are
maintained in accordance with the Federal Energy Regulatory Commission's (FERC)
Uniform System of Accounts as adopted by the Public Utility Commission of Texas
(PUC). Lone Star Gas and Lone Star Pipeline, divisions of ENSERCH, are subject
to the accounting requirements prescribed by the National Association of
Regulatory Utility Commissioners.
 
     Property, Plant and Equipment -- Electric and gas utility plant is stated
at original cost less certain regulatory disallowances. The cost of property
additions to electric and gas utility plant includes labor and materials,
applicable overhead and payroll-related costs and an allowance for funds used
during construction (AFUDC). Other property is stated at cost.
 
     Allowance For Funds Used During Construction -- AFUDC is a cost accounting
procedure whereby amounts based upon interest charges on borrowed funds and a
return on equity capital used to finance construction are added to utility
plant. The accrual of AFUDC is in accordance with generally accepted accounting
principles for the industry, but does not represent current cash income.
 
     TU Electric capitalizes AFUDC, compounded semi-annually, on expenditures
for ongoing construction work in progress (CWIP) and nuclear fuel in process not
otherwise allowed in rate base by regulatory authorities. For 1997, 1996 and
1995, TU Electric used rates of 7.9%, 7.4%, and 7.7%, respectively. Other
regulated subsidiaries also capitalize AFUDC.
 
     Depreciation of Property, Plant and Equipment -- Depreciation of the
Company's electric and gas utility plant is generally based upon an amortization
of the original cost of depreciable properties (net of regulatory disallowances)
on a straight-line basis over the estimated service lives of the properties.
Depreciation also includes an amount for TU Electric's Comanche Peak
decommissioning costs which is being accrued over the lives of the units and
deposited to external trust funds. (See Note 15.) Depreciation of all other
plant and equipment generally is determined by the straight-line method over the
useful life of the asset. Consolidated depreciation as a percent of average
depreciable property for the Company and System Companies approximated 2.6% for
1997, 2.7% for 1996 and 2.6% 1995.
 
     Amortization of Nuclear Fuel and Refueling Outage Costs -- The amortization
of nuclear fuel in the reactors (net of regulatory disallowances) is calculated
on the units of production method and is included in nuclear fuel expense. TU
Electric accrues a provision for costs anticipated to be incurred during the
next scheduled Comanche Peak nuclear generating station (Comanche Peak)
refueling outage.
 
     Foreign Currency Translation -- The assets and liabilities of foreign
operations denominated in foreign currencies are translated at rates in effect
at year end. Revenues and expenses are translated at average rates for the
applicable periods. Generally, local currencies are considered to be the
functional currency, and adjustments resulting from such translation are
included in the cumulative currency translation adjustment, a separate component
of common stock equity.
 
     Derivative Instruments -- The Company enters into interest rate swaps to
reduce exposure to interest rate fluctuations. Amounts paid or received under
interest rate swap agreements are accrued as interest rates change and are
recognized over the life of the agreements as adjustments to interest expense.
The Company also enters into derivative contracts in connection with the
wholesale purchases of electric energy by Eastern Energy and defers the impact
of changes in the market value of the contracts, which serve as hedges, until
the related transaction is completed. (See Note 9.)
                                      V-22
<PAGE>   268
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     Energy Marketing Activities -- The Company, through its natural gas
marketing subsidiary, Enserch Energy Services, Inc. (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 principally
involving physical delivery of natural gas and derivative financial instruments,
including options, swaps, futures and other contractual arrangements. The
derivative transactions are concentrated with established energy companies and
major financial institutions. EES uses the mark-to-market method of valuing and
recognizing earnings from firm contractual commitments to purchase and sell
natural gas in the future and from its portfolio of derivative financial
instruments, including options, swaps, futures and other contractual
commitments. (See Note 9.)
 
     Revenues -- Electric revenues include billings under approved rates
(including a fixed fuel factor) applied to meter readings each month on a cycle
basis and an accrual of base rate revenue for energy provided after cycle
billing but not billed through the end of each month. Revenues also include an
amount for under-or over-recovery of fuel revenue representing the difference
between actual fuel cost and billings under the approved fixed fuel factor and a
provision that generally allows recovery through a Power Cost Recovery Factor,
on a monthly basis, of the capacity portion of purchased power cost and wheeling
cost from qualifying facilities not included in base rates. The fuel portion of
purchased power cost is included in the fixed fuel factor. A utility's fuel
factor can be revised upward or downward every six months, according to a
specified schedule. A utility is required to petition to make either surcharges
or refunds to ratepayers, together with interest based on a twelve month average
of prime commercial rates, for any material cumulative under- or over-recovery
of fuel costs. If the cumulative difference of the under- or over-recovery, plus
interest, is in excess of 4% of the annual estimated fuel costs most recently
approved by the PUC, it will be deemed to be material. A procedure exists for an
expedited change in fuel factors in the event of an emergency. Final
reconciliation of fuel costs must be made either in a reconciliation proceeding,
which may cover no more than three years and no less than one year, or in a
general rate case. (See Note 13.)
 
     The city gate rate for the cost of gas Lone Star Gas ultimately delivers to
residential and commercial customers is established by the Railroad Commission
of Texas (RRC) and provides for full recovery of the actual cost of gas
delivered, including out-of-period costs such as gas-purchase contract
settlement costs. The rates Lone Star Gas charges its residential and commercial
customers are established by the municipal governments of the cities and towns
served, with the RRC having appellate jurisdiction. Lone Star Gas records
revenues on the basis of cycle meter readings throughout the month and accrues
revenues for gas delivered from the meter reading dates to the end of the month.
The rate Lone Star Pipeline charges to Lone Star Gas for transportation and
storage of gas ultimately consumed by residential and commercial customers is
established by the RRC.
 
     Income Taxes -- The Company and its domestic (U.S.) subsidiaries file a
consolidated federal income tax return, and federal income taxes are allocated
to subsidiaries based upon their respective taxable income or loss. Investment
tax credits are normally amortized to income over the estimated service lives of
the properties. Deferred income taxes are currently provided for temporary
differences between the book and tax basis of assets and liabilities (including
the provision for regulatory disallowances). Certain provisions of SFAS 109
provide that regulated enterprises are permitted to recognize such adjustments
as regulatory tax assets or tax liabilities if it is probable that such amounts
will be recovered from, or returned to, customers in future rates. Accordingly,
at December 31, 1997, the consolidated balance sheet includes a net regulatory
tax asset of $1,249,338,000.
 
     Effective January 1, 1997, TU Electric's state franchise tax status changed
from a tax based on net taxable capital to a tax based on net taxable earned
surplus. Certain other subsidiaries of the Company are also taxed on the earned
surplus method. Net taxable earned surplus is based on the federal income tax
return. The portion of the franchise tax calculated under the earned surplus
method is an income tax.
 
     Income Taxes on Undistributed Earnings of Foreign Subsidiaries -- The
Company intends to reinvest the earnings of its foreign subsidiaries into those
businesses. Accordingly, no provision has been made for taxes which would be
payable if such earnings were to be repatriated to the United States.

<PAGE>   269
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     Earnings Per Share -- Under the provisions of SFAS 128, which became
effective in December 1997, basic earnings per share applicable to common stock
are based on the weighted average number of common shares outstanding during the
year. Diluted earnings per share since the Merger include the effect of
potential common shares resulting from the assumed conversion of the outstanding
6 3/8% Convertible Subordinated Debentures due 2002 of ENSERCH and the exercise
of all outstanding stock options. For the period from the effective date of the
Merger to December 31, 1997, 999,492 shares were added to the average shares
outstanding for 1997 and $1,545,964 of after-tax interest expense was added to
earnings applicable to common stock for the purpose of calculating diluted
earnings per share. Previously reported earnings per share amounts for prior
years were not affected by the new standard.
 
     Consolidated Cash Flows -- For purposes of reporting cash flows, temporary
cash investments purchased with a remaining maturity of three months or less are
considered to be cash equivalents.
 
     The schedule below details the Company's cash payments and noncash
investing and financing activities:

     Regulatory Assets and Liabilities -- SFAS 71 applies to utilities which
have cost-based rates established by a regulator and charged to and collected
from customers. In accordance with this statement, the Company's regulated
subsidiaries may defer the recognition of certain costs (regulatory assets) and
certain obligations (regulatory liabilities) that, as a result of the rate
making process, have probable corresponding increases or decreases in future
revenues. These regulatory assets and liabilities are being amortized over
various periods of 5 to 40 years and are currently included in rates, or are
expected to be included in future rates.

     Future significant changes in regulation or competition could affect the
regulated subsidiaries' ability to meet the criteria for continued application
of SFAS 71 and may affect their ability to recover these regulatory assets from,
or refund these regulatory liabilities to, customers. If the affected System
Companies were to discontinue the application of SFAS 71, they would be required
to assess the recoverability of certain assets, including plant and regulatory
assets, and, if impaired, to write down the assets to reflect their fair market
value. The Company cannot predict the ultimate outcome of the ongoing efforts
that are taking place to restructure the electric utility industry or whether
the outcome of such efforts will have a material effect on its financial
position, results of operation or cash flows. However, the Company has no
current knowledge of planned or impending actions by regulators, including the
legislature of the State of Texas, that would affect recoverability of its plant
and net regulatory assets.
 
3  SHORT-TERM FINANCING
 
     The Company had outstanding short-term borrowings of $614,442,000,
consisting of commercial paper of $570,000,000 and bank borrowings of
$44,442,000, at December 31, 1997. The weighted average interest rates on such
borrowings was 6.18% at December 31, 1997. During the years 1997, 1996 and 1995,
the Company's average amounts outstanding for short-term borrowings, including
amounts classified as long-term, were $1,222,176,000, $593,660,000 and
$149,806,000, respectively. Weighted average interest rates for short-term
borrowings during such periods were 5.86%, 5.94% and 6.33%, respectively.
 
     At December 31, 1997, the Company, 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 the Company, 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 the Company at December 31, 1997, from banks or
other lenders, was $2,150,000,000.
 
     In addition, certain non-U.S. subsidiaries have revolving credit agreements
aggregating approximately $95,000,000, of which $61,000,000 was outstanding at
December 31, 1997. These revolving credit agreements expire at various dates
through 2000.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     The Company intends to refinance up to $990,440,000 of its current
short-term borrowings beyond one year of the balance sheet date of December 31,
1997. As a result, such amount has been reclassified from notes
payable -- commercial paper to long-term debt on the Company's 1997 Balance
Sheet (see Note 8). If necessary, the Company would draw upon Facility B if such
amount were not refinanced in the normal course of business.
 
4  COMMON STOCK
 
     The Company has an Automatic Dividend Reinvestment and Common Stock
Purchase Plan (DRIP) and an Employees' Thrift Plan of the Texas Utilities
Company System (Thrift Plan). During each of the last three years, requirements
under the DRIP and Thrift Plan have been met through open market purchases of
the Company's common stock.
 
     At December 31, 1997, the Thrift Plan had an obligation of $250,000,000
outstanding in the form of a note, which the Company purchased from the original
third-party lender and recorded as a reduction to common equity. At December 31,
1997, the Thrift Plan trustee held 5,375,158 shares of common stock (LESOP
Shares) of the Company under the leveraged employee stock ownership provision of
the Thrift Plan. LESOP Shares are held by the trustee until allocated to Thrift
Plan participants when required to meet the System Companies' obligations under
terms of the Thrift Plan. The Thrift Plan uses dividends on the LESOP Shares
held and contributions from the System Companies, if required, to repay interest
and principal on the note. Common stock equity increases at such time as LESOP
Shares are allocated to participants' accounts although shares of common stock
outstanding include unallocated LESOP Shares held by the trustee. Allocations to
participants' accounts in each of the years 1997 and 1995 increased common stock
equity by $8,115,000; 1996 increased by $8,137,000.
 
     The Long-Term Incentive Compensation Plan was approved and adopted by the
directors of the Company and approved by the shareholders in 1997. The purpose
of the plan is to assist the Company in attracting, retaining and motivating
executive officers and other key employees essential to the success of the
Company through performance-related incentives linked to long-range performance
goals. The plan is a comprehensive, stock-based incentive compensation plan,
providing for discretionary awards (Awards) of incentive stock options,
nonqualified stock options, stock appreciation rights, restricted stock,
restricted stock units, performance shares, performance units, bonus stock and
other stock-based awards. All Awards will be made in, or based on the value of,
the Company's common stock. The maximum number of shares of common stock for
which Awards may be granted under the plan is 2,500,000 subject to adjustment in
the event of a merger, consolidation, reorganization, recapitalization, stock
dividend, stock split, or other similar event. During 1997, the Board of
Directors authorized the award of 61,000 shares of restricted common stock,
which were issued in 1997 subject to performance and vesting requirements over a
three to five year period. No stock options were granted.
 
     At December 31, 1997, 14,154,372 shares of the authorized but unissued
common stock of the Company were reserved for issuance and sale pursuant to the
above plans, for conversion of the 6 3/8% Convertible Subordinated Debentures
due 2002 (see Note 8) and for other purposes.
 
     In November 1997, the Company's Board of Directors increased the common
stock repurchase limit to $350 million of which $148,780,000 was used as of
December 31, 1997 to purchase and retire 4,015,000 shares of the Company's
issued and outstanding common stock during 1997. The cost of the repurchased
shares, to the extent it exceeded the estimated amount received upon their
original issuance, has been charged to retained earnings.
 
     The Company has 50,000,000 authorized shares of serial preference stock
having a par value of $25 a share, none of which has been issued.

5  DIVIDEND RESTRICTIONS OF SUBSIDIARIES
 
     The articles of incorporation and/or the mortgages, as supplemented, and
certain other debt instruments of TU Electric and SESCO contain provisions
which, under certain conditions, restrict distributions on or acquisitions of
common stock. At December 31, 1997, $29,236,000 of retained earnings of TU
Electric, and $13,970,000 of retained earnings of SESCO, were thus restricted as
a result of such provisions.

     The carrying value of preferred stock subject to mandatory redemption is
being increased periodically to equal the redemption amounts at the mandatory
redemption dates with a corresponding increase in preferred stock dividends.
 
     During the year ended December 31, 1997, TU Electric redeemed or purchased
5,578,816 shares of its preferred stock (including 3,989,640 shares purchased by
the Company in March 1997 pursuant to a tender offer and subsequently sold to TU
Electric) with annual dividend rates ranging from 4.00% to 9.64% at a total cost
of approximately $553,093,000. In January 1998, TU Electric redeemed all of the
outstanding shares of the $8.20 series preferred stock, and ENSERCH redeemed the
Series E Adjustable Rate Preferred Stock, in each case at 100% of the
liquidation price plus accumulated and unpaid dividends.
 
7  TU ELECTRIC OBLIGATED, MANDATORILY REDEEMABLE, PREFERRED SECURITIES OF
   SUBSIDIARY TRUSTS HOLDING SOLELY DEBENTURES OF TU ELECTRIC
 
     Five statutory business trusts, each a TU Electric Trust, have been
established as financing subsidiaries of TU Electric for the purposes, in each
case, of issuing common and preferred trust securities and holding Junior
Subordinated Debentures issued by TU Electric (Debentures). TU Electric Capital
I, II and III preferred trust securities have a liquidation preference of $25
per unit, and TU Electric Capital IV and V preferred trust securities have a
liquidation preference of $1,000 per unit (Capital Securities). The Debentures
held by each TU Electric Trust are its only assets. The interest on Trust assets
matches the dividend rates on the trust securities. 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.
 
     The preferred securities are subject to mandatory redemption upon payment
of the Debentures at maturity or upon redemption. The Debentures are subject to
redemption, in whole or in part at the option of TU Electric, at 100% of their
principal amount plus accrued interest, after an initial period during which
they may not be redeemed and at any time upon the occurrence of certain events.
The carrying value of the preferred securities is being increased periodically
to equal the redemption amounts at the mandatory redemption dates with a
corresponding increase in preferred securities distributions.

(a) Floating rate is determined quarterly based on LIBOR. The related interest
    rate swap fixes the rate at 7.183%.
 
     At December 31, 1997, TU Electric, with respect to its Capital IV
securities, had an interest rate swap agreement with a notional principal amount
of $100,000,000 expiring 2002 that fixed the rate on the securities at 7.183%
per annum.
 
     The combination of the obligations of TU Electric pursuant to agreements to
pay the expenses of each of the TU Electric Trusts and TU Electric's guarantees
of distributions with respect to trust securities, to the extent the issuing
trust has funds available therefor, constitutes a full and unconditional
guarantee by TU Electric of the obligations of each trust under the trust
securities it has issued. TU Electric is the owner of all the common trust
securities of each trust, which, in each case, constitutes 3% or more of the
liquidation amount of all the trust securities issued by such trust.
 
     In January 1998, TU Electric redeemed all of the outstanding shares of the
TU Electric Capital II preferred trust securities at 100% of the liquidation
amount of $25 per preferred security, plus accumulated and unpaid dividends.

(a)  Interest rates in effect at December 31, 1997 are presented. Taxable
     pollution control series are in a flexible rate mode. Series 1991D bonds
     due 2021 were remarketed on June 1, 1995 for rate periods up to 180 days
     and are secured by an irrevocable letter of credit with maturities in
     excess of one year. Series 1993 bonds due 2023 will be remarketed for
     periods of less than 270 days and are secured by an irrevocable letter of
     credit with maturities in excess of one year.
 
(b)  Interest rates in effect at December 31, 1997 are presented. These series
     are in a flexible mode with varying interest rates and, while in such mode,
     will be remarketed for periods of less than 270 days and are secured by an
     irrevocable letter of credit with maturities in excess of one year.
 
(c)  Interest rates in effect at December 31, 1997 are presented . These series
     are in a daily mode with varying interest rates and are supported by either
     municipal bond insurance policies and standby bond purchase agreements or
     are secured by irrevocable letters of credit with maturities in excess of
     one year.
 
(d)  In 1990, TU Electric purchased the ownership interest in Comanche Peak of
     Tex-La Electric Cooperative of Texas, Inc. (Tex-La) and assumed debt of
     Tex-La payable over approximately 32 years. The assumption is secured by a
     mortgage on the acquired interest. The Company has guaranteed these
     payments.
 
(e)  Eastern Energy has entered into cross-currency and interest rate swap
     agreements expiring on concurrent dates with the underlying fixed rate debt
     through 2016. Such agreements effectively convert these fixed rate U.S.
     dollar denominated Senior Notes to a floating rate Australian Dollar
     liability based on the Australian Bank Bill Swap rate plus a margin. At
     December 31, 1997, such floating rates ranged from 5.29% to 8.45%.
 
(f)  Includes the Company's $990,440,000 reclassified short-term debt (see Note
     3). Also includes Eastern Energy's $297,837,000 Multi Option Credit
     Facility due 2001 with a floating interest rate of 5.44% on December 31,
     1997 and Eastern Energy's $128,451,000 reclassified short-term debt (all of
     which is included under interest rate swap agreements with notional
     principal amounts of $627,539,000 expiring at various dates through 2002
     with fixed interest rates ranging from 5.29% to 8.45% per annum and forward
     contracts with notional principal amounts of $45,521,000 expiring at
     various dates through 1998 with an average rate of 4.8%).
 
     Long-term debt of the Company does not include Junior Subordinated
Debentures held by each TU Electric Trust. (See Note 7.)
 
     The ENSERCH convertible subordinated debentures, which have an interest
rate of 6 3/8%, are due in 2002 and effective with the Merger, each $1,000 of
the $90,750,000 total principal amount outstanding became convertible into
25.947 shares of TUC common stock at the option of the debenture holder. The
debentures may be redeemed at 101.27% of the principal amount, plus accrued
interest, through March 31, 1998 and at declining premiums thereafter. The
Company currently intends to redeem these debentures in 1998.
 
     Sinking fund and maturity requirements for the years 1998 through 2002

     TU Electric's and SESCO's first mortgage bonds are secured by mortgages and
deeds of trust with major financial institutions. Electric plant of TU Electric
and SESCO is generally subject to the liens of their respective mortgages.
 
9  DERIVATIVE INSTRUMENTS
 
     The Company enters into derivative instruments, including options, swaps,
futures and other contractual commitments to manage market risks related to
changes in interest rates and commodity price exposures. The Company's
participation in derivative transactions, except for the gas marketing
activities, have been designated for hedging purposes and are not held or issued
for trading purposes. (For a discussion of accounting policies relating to
derivative instruments, see Note 2.)
 
     Interest Rate Risk Management -- At December 31, 1997, Eastern Energy had
interest rate swaps outstanding with an aggregate notional amount of
$977,500,000. These swap agreements establish a mix of fixed and variable
interest rates on the outstanding debt and have remaining terms up to 19 years.
(See Note 8.)
 
     At December 31, 1997, TU Electric had 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 that fixed the rate at 7.183% per
annum. (See Note 7.)
 
     At December 31, 1997, there were $50,900,000 of net unrealized deferred
hedging losses on interest rate swaps.
 
     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 and other distribution companies were required to
enter into wholesale market contracts to cover a substantial majority of its
forecasted franchise load through the end of 2000. Eastern Energy also maintains
a strategy that is aimed at seeking hedging contracts with individual generators
to cover forecast contestable loads. 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. During 1997, the average spot price for
electric energy from the pool approximated $14 per megawatt-hour (MWh) as
compared with the average fixed price of Eastern Energy's electric energy under
its contracts of approximately $29 per MWh. At December 31, 1997, Eastern
Energy's contracts related to its forecasted contestable and franchise load
cover a notional volume of approximately 15.6 million MWh's for 1998 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 -- 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. The Company closely monitors its exposure to market risk. The
Company utilizes a number of methods to monitor market risk, including
sensitivity analysis. The exposure for fixed price natural gas purchase and sale
commitments, and derivative financial instruments, including options, swaps,
futures and other contractual commitments, is based on a methodology that uses a
five-day holding period and a 95% confidence level. EES uses market-implied
volatilities to determine its exposure to market risk. Market risk is estimated
as the potential loss in fair value resulting from at least a 15% change in
market factors which may differ from actual results. Using 15%, the most adverse
change in fair value at December 31, 1997 as a result of this analysis was a
reduction of $1.1 million.

<PAGE>   279
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     EES enters into contracts to purchase and sell natural gas for physical
delivery in the future. At December 31, 1997, EES had net commitments to sell
approximately 50.6 billion cubic feet (Bcf) of natural gas through the year 2003
with offsetting net financial positions to purchase approximately 61.3 Bcf.
 
     Concurrent with the Merger, EES conformed its accounting for its gas
marketing activities to mark-to-market accounting. Under mark-to-market
accounting, changes (whether positive or negative) in the value of contractual
commitments to purchase and sell natural gas in the future and from its
portfolio of derivative financial instruments, including options, swaps, futures
and other contractual commitments are recognized as an adjustment to operating
revenues in the period of change. The market prices used to value these
transactions reflect management's best estimate of market prices considering
various factors including closing exchange and over-the-counter quotations, time
value of money and volatility factors underlying the commitments. These market
prices are adjusted to reflect the potential impact of liquidating EES's
position in an orderly manner over a reasonable period of time under present
market conditions.
 
     EES has a number of risks and costs associated with the future contractual
commitments included in its natural gas portfolio, including credit risks
associated with the financial condition of counterparties, product location
(basis) differentials and other risks that management policies dictate. EES
continuously monitors the valuation of identified risk and adjusts the portfolio
valuation based on present market conditions. Reserves are established in
recognition that certain risks exist until delivery of natural gas has occurred,
counterparties have fulfilled their financial commitments and related financial
instruments mature or are closed out.
 
     The following table displays the mark-to-market values of EES's natural gas
marketing risk management assets and liabilities at December 31, 1997 and the
average value for the period from August 5, 1997 through December 31, 1997:

     EES incurred net trading losses of $286,000 from gas marketing activities

     Credit Risk -- Credit risk relates to the risk of loss that the Company
would incur as a result of nonperformance by counterparties to their respective
derivative instruments. The Company maintains credit policies with regard to its
counterparties that management believes significantly minimize overall credit
risk. The Company does not obtain collateral to support the agreements but
monitors the financial viability of counterparties and believes its credit risk
is minimal on these transactions. The Company believes the risk of
nonperformance by counterparties is minimal.

     At December 31, 1997, the Company had approximately $590 million of
alternative minimum tax credit carryforwards available to offset future tax
payments. At December 31, 1997, ENSERCH had $445 million of net operating loss
(NOL) carryforwards which begin to expire in 2003. Such NOL's were generated by

ENSERCH and subsidiaries prior to the Merger and can be used only to offset
future taxable income generated by ENSERCH and subsidiaries pursuant to Section
382 of the Internal Revenue Code. The Company expects to fully utilize such
NOL's prior to their expiration date.
 
     Separately, the ENSERCH consolidated income tax returns have been audited
and settled with the Internal Revenue Service (IRS) through the year 1992. The
IRS is currently auditing the year 1993 and as yet no notice of proposed
adjustments has been issued. The IRS has indicated that it will commence an
audit of ENSERCH's returns for the years 1994 through 1997 in 1998. To the
extent that adjustments to income tax accounts for periods prior to the Merger
are required as a result of an IRS audit, the adjustment will be added to or
deducted from goodwill in accordance with the provisions of SFAS 109.
 
11  RETIREMENT PLANS AND OTHER POSTRETIREMENT BENEFITS
 
     Most employees of System Companies are covered by defined benefit pension
plans which provide benefits based on years of service and average earnings. At
the date of their acquisition by the Company, both ENSERCH and LCC had defined
benefit pensions plans covering most of their employees and providing benefits
similar to those provided to employees of other System Companies. As a part of
the purchase accounting for ENSERCH and LCC, their accrued pension liabilities
were adjusted to recognize all previously unrecognized gains or losses arising
from past experience different from that assumed, the effects of changes in
assumptions, all unrecognized prior service costs and the remainder of any
unrecognized obligation or asset existing at the date of the initial application
of SFAS 87 by the respective company. These adjustments to the accrued pension
liability, to the extent associated with rate-regulated operations, were
recorded as regulatory assets or liabilities and, to the extent associated with
non-regulated operations, as goodwill.
 
     Effective January 1, 1998, the ENSERCH retirement plan was merged into
another retirement plan of the Company. Also, effective during 1998, employees
of certain of the Company's emerging business units will be eligible to
participate in a cash balance plan, rather than the traditional defined benefit
plans. This change, which affects a relatively small percentage of employees,
was made in connection with overall changes in the compensation plans of these
business units designed to bring them closer to the prevailing practices of the
companies in the industries in which they compete.
 
     In connection with the ENSERCH acquisition, certain employees of ENSERCH
and other System Companies were offered and accepted an early retirement option.
Effects of the early retirement option associated with ENSERCH employees were
included in purchase accounting adjustments as regulatory assets or goodwill, as
appropriate. Effects of the early retirement option associated with employees of
other System Companies were recorded as regulatory assets, or liabilities.

     In addition to the retirement plans, the System Companies offer certain
health care and life insurance benefits to substantially all employees,
including those of ENSERCH and LCC but excluding those of Eastern Energy, and
their eligible dependents at retirement. Benefits received vary in level
depending on years of service and retirement dates. The purchase accounting
adjustments described above for the retirement plans of ENSERCH and LCC were
also applied to the accrued liabilities for the post employment health care and
life insurance benefits.

     The expected increase in costs of future benefits covered by the plan is
projected using a health care cost trend rate of 5.0% in 1998 and thereafter. A
one percentage point increase in the assumed health care cost trend rate in each
future year would increase the APBO at December 31, 1997 by approximately $65.9
million for the System Companies, and other postretirement benefits cost for
1997 by approximately $9.8 million.
 
12  SALES OF ACCOUNTS RECEIVABLE
 
     The Company has facilities with financial institutions whereby it is
entitled to sell and such financial institutions may purchase, on an ongoing
basis, undivided interests in customer accounts receivable representing up to an
aggregate of $450,000,000, including $100,000,000 related to ENSERCH in 1997.
Additional receivables are continually sold to replace those collected. At
December 31, 1997 and 1996, accounts receivable was reduced by $400,000,000 and
$300,000,000, respectively, to reflect the sales of such receivables to
financial institutions under such agreements.
 
13  REGULATION AND RATES
 
     Docket 9300 -- The PUC's final order (Order) in connection with TU
Electric's January 1990 rate increase request (Docket 9300) was reviewed by the
250th Judicial District Court of Travis County, Texas, (District Court) and
thereafter was appealed to the Court of Appeals for the Third District of Texas
and to the Supreme Court of Texas (Supreme Court). As a result of such review
and appeals, an aggregate of $909 million of disallowances with respect to TU
Electric's reacquisitions of minority owners' interests in Comanche Peak, which
had previously been recorded as a charge to the Company's earnings, has been
remanded to the District Court with instructions that it be remanded to the PUC
for reconsideration on the basis of a prudent investment standard. On remand,
the PUC would also be required to reevaluate the appropriate level of TU
Electric's construction work in progress included in rate base in light of its
financial condition at the time of the initial hearing. In January 1997, the
Supreme Court denied a motion for rehearing on the Comanche Peak minority owners
issue filed by the original complainants. TU Electric cannot predict the outcome
of the reconsideration of the Order on remand by the PUC.
 
     In its decision, the Supreme Court also affirmed the previous $472 million
prudence disallowance related to Comanche Peak. Since the Company has previously
recorded a charge to earnings for this prudence disallowance, the Supreme
Court's decision did not have an effect on the Company's current financial
position, results of operation or cash flows.
 
     Docket 11735 -- In July 1994, TU Electric filed a petition in the 200th
Judicial District Court of Travis County, Texas to seek judicial review of the
final order of the PUC granting a $449 million, or 9.0%, rate
 
                                      V-39

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
increase in connection with TU Electric's January 1993 rate increase request of
$760 million, or 15.3% (Docket 11735). Other parties to the PUC proceedings also
filed appeals with respect to various portions of the order.
 
     Dockets 15638 and 15840 -- In May 1996, TU Electric filed with the PUC its
transmission cost information and tariffs for open-access wholesale transmission
service (Docket 15638) in accordance with PUC rules adopted in February 1996.
These tariffs also provide for generation-related ancillary services necessary
to support wholesale transactions. In August 1997, the PUC approved final
tariffs for TU Electric and implemented rates for other transmission providers
within the Electric Reliability Council of Texas (ERCOT) (Docket 15840). Under
rates implemented by the PUC, TU Electric's payments for transmission service
will exceed its revenues for providing transmission service. The PUC has adopted
a rate-moderation plan that will minimize the impact of the new pricing
mechanism for the first three years the rules are in effect. As such, the
current maximum impact on TU Electric for 1998 is an $8.52 million deficit,
which, in the opinion of TU Electric, is not expected to have a material effect
on its financial position, results of operation or cash flows.
 
     Docket 17250 -- In late 1996, as part of its regular earnings monitoring
process, the PUC staff advised the PUC, after reviewing the 1995 Electric
Investor-Owned Utilities Earnings Report of TU Electric, 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 longer-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.
 
     Docket 18490 -- On December 17, 1997, TU Electric, together with the PUC
General Counsel, the Office of Public Utility Counsel and various other parties
interested in TU Electric's rates and services, filed with the PUC a stipulation
and joint application which, if granted would, among other things: (i) result in
permanent retail base rate credits beginning January 1, 1998, of 4% for
residential customers, 2% for general service secondary customers and 1% for all
other retail customers, (ii) result in additional permanent retail base rate
credits beginning January 1, 1999, of 1.4% for residential customers, (iii)
impose a 11.35% cap on TU Electric's rate of return on equity during 1998 and
1999, with any sums earned above that cap being applied as additional nuclear
production depreciation, (iv) allow TU Electric to record depreciation
applicable to transmission and distribution assets in 1998 and 1999 as
additional depreciation of nuclear production assets, (v) establish an updated
cost of service study that includes interruptible customers as customer classes,
(vi) result in the permanent dismissal of pending appeals of prior PUC orders
including Docket No. 11735, if all other parties that have filed appeals of
those dockets also dismiss their appeals, (vii) result in the stay of any
proceedings in the removal of Docket 9300 prior to January 1, 2000, and, (viii)
result in all gains from off-system sales of electricity in excess of the amount
included in base rates being flowed to customers through the fuel factor.
 
     The PUC has until March 31, 1998 to approve or reject the stipulation and
joint application. Otherwise, TU Electric may terminate the base rate reductions
and all other aspects of the proposal upon giving two weeks notice to the PUC.
 
     Lone Star Gas and Lone Star Pipeline Rates -- In October 1996, Lone Star
Pipeline filed a request with the RRC to increase the rate it charges Lone Star
Gas 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
 
                                      V-40

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
previously in effect were set by the RRC in 1982. In September 1997, the RRC
issued an order reducing the charges by Lone Star Pipeline to Lone Star Gas for
storage and transportation services. In that order, the RRC did authorize
separate charges for the Lone Star Pipeline storage and transportation services,
a separate charge by Lone Star Gas for the cost of aggregating gas supplies, and
a continuation of the 100% flow through of purchased gas expense. The RRC also
imposed some new criteria for affiliate gas purchases and a new reconciliation
procedure that will require a review of purchased gas expenses every three
years. The RRC order has become final, but is being appealed by several parties
including Lone Star Pipeline and Lone Star Gas. The rates authorized by the
order became effective on December 1, 1997, and will result in an annual margin
reduction of approximately $8.2 million.
 
     On August 20, 1996, the RRC ordered a general inquiry into the rates and
services of Lone Star Gas, most notably a review of historic gas cost and gas
acquisition practices since the last rate setting. The inquiry docket has been
separated into different phases. Two of the phases, conversion to the NARUC
account numbering system and unbundling, have been dismissed by the RRC, and one
other phase, rate case expense, is pending RRC action on the basis of a
stipulation of all parties. In the phase dealing with historic gas cost and gas
acquisition practices, Lone Star Gas and Lone Star Pipeline have filed a motion
for summary disposition stating that any retroactive rate action would be
inappropriate and unlawful. Settlement discussions with intervenor cities are
ongoing. If the motion for summary disposition is denied, a hearing has been
scheduled to begin in August 1998. A number of management and transportation
related issues have been placed in a separate phase which still has an undefined
scope and is being held in abeyance pending the resolution of the phase dealing
with gas costs. Management believes that gas costs were prudently incurred and
were properly accounted for and recovered through the gas cost recovery
mechanism previously approved by the RRC. At this time, management is unable to
determine the ultimate outcome of the inquiry.
 
     Fuel Cost Recovery Rule -- Pursuant to a PUC rule, the recovery of TU
Electric's eligible fuel costs is provided through fixed fuel factors. The rule
allows a utility's fuel factor to be revised upward or downward every six
months, according to a specified schedule. A utility is required to petition to
make either surcharges or refunds to ratepayers, together with interest based on
a twelve month average of prime commercial rates, for any material, as defined
by the PUC, cumulative under- or over-recovery of fuel costs. If the cumulative
difference of the under- or over-recovery, plus interest, is in excess of 4% of
the annual estimated fuel costs most recently approved by the PUC, it will be
deemed to be material. In accordance with PUC approvals, TU Electric has, since
the inception of the rule in 1986, made thirteen refunds of over-collected fuel
costs and two surcharges of under-collected fuel costs. The most recent refund
was made pursuant to a petition filed by TU Electric in July 1997 to refund
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. The two surcharges (one
in the amount of $147.3 million and the other in the amount of $93 million) have
been appealed by certain intervenors to district courts of Travis County, Texas.
In those appeals, those parties are contending that the PUC is without authority
to allow a fuel cost surcharge without a hearing and resultant findings that the
costs are reasonable and necessary and that the prices charged to TU Electric by
supplying affiliates are no higher than the prices charged by those affiliates
to others for the same item or class of items. TU Electric is unable to predict
their outcome.
 
     Fuel Reconciliation Proceeding -- 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 $81 million of eligible fuel related costs (including
interest of $12 million) 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
 
                                      V-41
<PAGE>   287
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
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.
 
     Flexible Rate Initiatives -- TU Electric continues to offer flexible rates
in over 160 cities with original regulatory jurisdiction within its service
territory (including the cities of Dallas and Fort Worth) to existing
non-residential retail and wholesale customers that have viable alternative
sources of supply and would otherwise leave the system. TU Electric also
continues to offer in those cities an economic development rider to attract new
businesses and to encourage existing customers to expand their facilities as
well as an environmental technology rider to encourage qualifying customers to
convert to technologies that conserve energy or improve the environment. TU
Electric will continue to pursue the expanded use of flexible rates when such
rates are necessary to be price-competitive.
 
     Integrated Resource Plan -- In October 1994, TU Electric filed an
application for approval by the PUC of certain aspects of its Integrated
Resource Plan (IRP) for the ten year period 1995 -- 2004. The IRP, developed as
an experimental pilot project in conjunction with regulatory and customer
groups, included the acquisition of electric energy through a competitive
bidding process of third party-supplied demand-side management resources and
renewable resources. In August 1995, the PUC remanded the case to an
Administrative Law Judge for development of a solicitation plan and to more
closely conform the TU Electric 1995 IRP to new state legislation that required
the PUC to adopt a state-wide integrated resource planning rule by September 1,
1996. In January 1996, TU Electric filed an updated IRP with the PUC along with
a proposed plan for the solicitation of resources through a competitive bidding
process. The PUC issued its final order on TU Electric's IRP in October 1996,
and modified the order in December 1996 and February 1997. The modified order
approved a flexible solicitation plan that will allow TU Electric to conduct up
to three optional resource solicitations for a total of 2,074 MW of demand-side
and supply-side resources prior to the filing of its next IRP in June 1999. TU
Electric is currently reviewing the need and timing for conducting the first of
these resource solicitations.
 
     In addition to its solicitation plan in the IRP docket, TU Electric
requested and received approval from the PUC to expand its Power Cost Recovery
tariff to provide current cost recovery of resource acquisition costs for
demand-side management resources acquired in the solicitations and for eight
previously approved demand-side management contracts entered into by TU Electric
to the extent such costs are not currently reflected in TU Electric's base
rates. OPEN-ACCESS TRANSMISSION -- In February 1996, pursuant to the 1995
amendments to PURA, the PUC adopted rules requiring each electric utility in
ERCOT to provide wholesale transmission and related services to other utilities
and non-utility power suppliers at rates, terms and conditions that are
comparable to those applicable to such utility's use of its own transmission
facilities.
 
     Under the rules, the PUC established a transmission pricing mechanism
consisting of an ERCOT system-wide component and a distance-sensitive component.
The ERCOT system-wide component provides that each load-serving entity in ERCOT
will pay a share of the ERCOT-wide transmission cost of service based on the
entity's load. The distance-sensitive component provides that a
distance-sensitive rate will be paid to utilities that own transmission
facilities, based on the impact of transmitting power and energy to loads. The
rates charged for using the transmission system are designed to ensure that all
market participants pay on a comparable basis to use the system. While all users
of the transmission grid pay rates that are comparably designed, the impact on
individual users will differ.
 
     In May 1996, TU Electric filed with the PUC, under Docket 15638, its
transmission cost information and tariffs for open-access wholesale transmission
service. These tariffs also provide for generation-related ancillary services
necessary to support wholesale transactions. Company-specific proceedings to
determine transmission rates for each transmission provider within ERCOT were
concluded in 1996. In August 1997, the
 
                                      V-42
<PAGE>   288
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
PUC approved final tariffs for TU Electric and implemented rates for other
transmission providers within ERCOT.
 
     As a result of the PUC rules, the organization and structure of ERCOT has
been changed to provide for equal governance among all wholesale electricity
market participants. These changes were made in order to facilitate wholesale
competition while ensuring continued reliability within ERCOT.
 
14  IMPAIRMENT OF ASSETS
 
     In September 1995, the Company recorded the impairment of several
non-performing assets pursuant to SFAS 121 which prescribes a methodology for
assessing and measuring impairments in the carrying value of certain assets. The
September 1995 impairment of the Company's assets, including the partially
completed Twin Oak and Forest Grove lignite-fueled facilities of TU Electric,
and Chaco Energy Company's (Chaco's) coal reserves in New Mexico, as well as
several minor assets, aggregated $1,233 million ($802 million after-tax). The
Company has determined that the Twin Oak and Forest Grove lignite-fueled
facilities are not necessary to satisfy TU Electric's capacity requirements as
currently projected due to changes in load growth patterns and availability of
alternative generation. The impairment of TU Electric's lignite-fueled
facilities has been measured based on management's current expectations that
these assets will either be sold or constructed outside the traditional
regulated utility business. The Company has determined that the Chaco coal
reserves will no longer be developed through traditional means due to ample
availability of alternative fuels at favorable prices. Chaco's impairment was
measured based on a significant decrease in the market value of the coal
reserves as determined by an external study. A variety of options are being
considered with respect to the Chaco coal reserves. (See Note 15.) The
impairment of these assets involved a write-down to their estimated fair values
using a valuation study based on the discounted expected future cash flows from
the respective assets' use. With respect to the other assets impaired, fair
values were determined based on current market values of similar assets.
 
15  COMMITMENTS AND CONTINGENCIES
 
     Capital Expenditures -- The Company's construction expenditures, excluding
AFUDC, are presently estimated at $886 million, $799 million and $852 million
for 1998, 1999 and 2000, respectively. Expenditures for nuclear fuel are
presently estimated at $104 million for 1998, $81 million for 1999 and $92
million for 2000.
 
     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 in estimated construction costs and
dates of completion. Commitments in connection with the construction program are
generally revocable subject to reimbursement to manufacturers for expenditures
incurred or other cancellation penalties.
 
     Clean Air Act -- The federal Clean Air Act, as amended (Clean Air Act)
includes provisions which, among other things, place limits on the sulfur
dioxide emissions produced by generating units. To meet these sulfur dioxide
requirements, the Clean Air Act provides for the annual allocation of sulfur
dioxide emission allowances to utilities. Under the Clean Air Act, utilities are
permitted to transfer allowances within their own systems and to buy or sell
allowances from or to other utilities. The Environmental Protection Agency
grants a maximum number of allowances annually to TU Electric based on the
amount of emissions from units in operation during the period 1985 through 1987.
TU Electric's capital requirements have not been significantly affected by the
requirements of the Clean Air Act. Although TU Electric is unable to fully
determine the cost of compliance with the Clean Air Act, it is not expected to
have a significant impact on the company. Any additional capital expenditures,
as well as any increased operating costs, associated with these new requirements
are expected to be recoverable through rates, as similar costs have been
recovered in the past.
 
     Purchased Power Contracts -- The System Companies have entered into
purchased power contracts to purchase portions of the generating output of
certain qualifying cogenerators and qualifying small power producers through the
year 2005. These contracts provide for capacity payments subject to a facility
meeting
                                      V-43

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
certain operating standards and energy payments based on the actual power taken
under the contracts. The cost of these and other purchased power contracts is
recovered currently through base rates, power cost and fuel recovery factors
applied to customer billings. Capacity payments under these contracts for the
years ended December 31, 1997, 1996 and 1995 were $240,174,000, $232,915,000,
and $229,340,000, respectively, for the Company.
 
     Assuming operating standards are achieved, future capacity payments under
the agreements are estimated as follows:

     Leases -- The System Companies have entered into operating leases covering
various facilities and properties including combustion turbines, transportation,

In connection with certain contracts, TU Electric has agreed, in effect, to
guarantee the principal, $30,005,000 at December 31, 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, for the years 1998 through 2001 as follows: $4,435,000 for each of the
years 1998 and 1999, $4,419,000 for 2000 and $4,422,000 for 2001. Payments made
by TU Electric, net of amounts assumed by a third party under such contracts,
for 1997, 1996 and 1995 were $3,750,000, $3,548,000, and $3,628,000,
respectively. 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 $69,395,000 remaining principal amount of bonds at December 31, 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. The Company and/or its subsidiaries are the guarantor on
various commitments and obligations of others aggregating some $45,000,000 at
December 31, 1997.
 
     Chaco Coal Properties -- Chaco has a coal lease agreement for the rights to
certain surface minable coal reserves located in New Mexico. The agreement
encompasses a minimum of 228 million tons of coal with
 
                                      V-44

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
provisions for minimum advance royalty payments of approximately $16 million per
year through 2017. The Company has entered into a surety agreement to assure the
performance by Chaco with respect to this agreement. Because of the present
ample availability of western coal at favorable prices from other mines, Chaco
has delayed plans to commence mining operations, and accordingly, is reassessing
its alternatives with respect to its coal properties, including seeking
purchasers thereof. (See Note 14.)
 
     Nuclear Insurance -- With regard to liability coverage, the Price-Anderson
Act (Act) provides financial protection for the public in the event of a
significant nuclear power plant incident. The Act sets the statutory limit of
public liability for a single nuclear incident currently at $8.9 billion and
requires nuclear power plant operators to provide financial protection for this
amount. As required, TU Electric provides this financial protection for a
nuclear incident at Comanche Peak resulting in public bodily injury and property
damage through a combination of private insurance and industry-wide
retrospective payment plans. As the first layer of financial protection, TU
Electric has purchased $200 million of liability insurance from American Nuclear
Insurers (ANI), which provides such insurance on behalf of a major stock
insurance pool, Nuclear Energy Liability Insurance Association. The second layer
of financial protection is provided under an industry-wide retrospective payment
program called Secondary Financial Protection (SFP).
 
     Under the SFP, each operating licensed reactor in the United States is
subject to an assessment of up to $79.275 million, subject to increases for
inflation every five years, in the event of a nuclear incident at any nuclear
plant in the United States. Assessments are limited to $10 million per operating
licensed reactor per year per incident. All assessments under the SFP are
subject to a 3% insurance premium tax which is not included in the amounts
above.
 
     With respect to nuclear decontamination and property damage insurance,
Nuclear Regulatory Commission (NRC) regulations require that nuclear plant
license-holders maintain not less than $1.06 billion of such insurance and
require the proceeds thereof to be used to place a plant in a safe and stable
condition, to decontaminate it pursuant to a plan submitted to and approved by
the NRC before the proceeds can be used for plant repair or restoration or to
provide for premature decommissioning. TU Electric maintains nuclear
decontamination and property damage insurance for Comanche Peak in the amount of
$4.1 billion, above which TU Electric is self-insured. The primary layer of
coverage of $500 million is provided by Nuclear Electric Insurance Limited
(NEIL), a nuclear electric utility industry mutual insurance company. The
remaining coverage includes premature decommissioning coverage and is provided
by ANI and Mutual Atomic Energy Liability Underwriters (MAELU) in the amount of
$1.1 billion and additional insurance from NEIL in the amount of $2.5 billion.
TU Electric is subject to a maximum annual assessment from NEIL of $26 million
in the event NML's and/or NEIL's losses under this type of insurance for major
incidents at nuclear plants participating in these programs exceed the
respective mutual's accumulated funds and reinsurance.
 
     TU Electric maintains Extra Expense Insurance through NEIL to cover the
additional costs of obtaining replacement power from another source if one or
both of the units at Comanche Peak are out of service for more than seventeen
weeks as a result of covered direct physical damage. The coverage provides for
weekly payments of $3.5 million for the first fifty-eight weeks and $2.8 million
for the next 104 weeks for each outage, respectively, after the initial
seventeen week period. The total maximum coverage is $494 million per unit. The
coverage amounts applicable to each unit will be reduced to 80% if both units
are out of service at the same time as a result of the same accident. Under this
coverage, TU Electric is subject to a maximum annual assessment of $9 million
per year.
 
     Gas Purchase Contracts -- Texas Utilities Fuel Company (Fuel Company) buys
gas under long-term intrastate contracts in order to assure reliable supply to
its customers. Many of these contracts require minimum purchases ("take-or-pay")
of gas. Based on Fuel Company's estimated gas demand, which assumes normal
weather conditions, requisite gas purchases are expected to substantially
satisfy purchase obligations for the year 1998 and thereafter.
 
                                      V-45

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     Lone Star Gas buys gas under long-term, intrastate contracts in order to
assure reliable supply to its customers. Many of these contracts require minimum
purchases of gas. Lone Star Gas has made accruals for payments that may be
required for settlement of gas-purchase contract claims asserted or that are
probable of assertion. Lone Star Gas continually evaluates its position relative
to asserted and unasserted claims, above-market prices or future commitments.
Management believes that Lone Star Gas has not incurred losses for which
reserves should be provided at December 31, 1997. Based on estimated gas demand,
which assumes normal weather conditions, requisite gas purchases are expected to
substantially satisfy purchase obligations for the year 1998 and thereafter.
 
     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, whereby
decommissioning costs are being recovered from customers over the life of the
plant and deposited in external trust funds (included in other investments). At
December 31, 1997, such reserve totaled $120,452,000 which includes an accrual
of $18,179,000 for the year ended December 31, 1997. As of December 31, 1997,
the market value of deposits in the external trust for decommissioning of
Comanche Peak was $160,062,000. 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 asset or a
regulatory liability. Realized earnings on funds deposited in the external trust
are recognized in the reserve. Based on a site-specific study completed during
1997 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 $271,000,000 and $404,000,000, 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 decommissioning costs based upon a 1992 site-specific
study through rates placed in effect under Docket 11735 (see Note 13). 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. In addition, the
marketable fixed income debt and equity securities in which assets of the
external trust are invested are subject to interest rate and equity price
sensitivity.
 
     TU Electric has a contract with the United States Department of Energy
(DOE) for the future disposal of spent nuclear fuel. In December 1996, the DOE
notified TU Electric that it did not expect to meet its obligation to begin
acceptance of spent nuclear fuel by 1998. TU Electric is unable to predict what
impact, if any, the DOE delay will have on TU Electric's future operations. The
disposal fee is at a cost to TU Electric of one mill per kilowatt-hour of
Comanche Peak net generation and is included in nuclear fuel expense.
 
GENERAL
 
     In addition to the above, the Company and System Companies are involved in
various legal and administrative proceedings which, in the opinion of the
Company, should not have a material effect upon its financial position, results
of operation or cash flows.

     The fair values of long-term debt and preferred stock subject to mandatory
redemption are estimated at the lesser of either the call price or the market
value as determined by quoted market prices, where available, or, where not
available the present value of future cash flows discounted at rates consistent
with comparable maturities for credit risk. The fair values of preferred
securities are based on quoted market prices. The carrying amounts reflected in
the Consolidated Balance Sheets for financial assets classified as current
assets and the carrying amounts for financial liabilities classified as current
liabilities approximate fair value due to the short maturity of such
instruments.
 
     Other investments include deposits in an external trust fund for nuclear
decommissioning of Comanche Peak. The trust funds are invested primarily in
fixed income debt and equity securities, which are considered as
available-for-sale. Any unrealized gains or losses are treated as regulatory
assets or regulatory liabilities, respectively.
 
     Common stock -- net has been reduced by the note receivable from the
trustee of the leveraged employee stock ownership provision of the Thrift Plan.
The fair value of such note is estimated at the lesser of the Company's call
price or the present value of future cash flows discounted at rates consistent
with comparable maturities adjusted for credit risk.
 
     The fair value of the financial guarantees is based on the present value of
the instruments' approximate cash flows discounted at the year-end risk free
rate for issues of comparable maturities adjusted for credit risk.
 
     Fair values for the System Companies' off-balance-sheet instruments
(interest rate and currency swaps) are based either on quotes or the cost to
terminate the agreements.

                             FINANCIAL INFORMATION
 
                             TEG GROUP INFORMATION
 
     Although Texas Utilities has included information concerning the TEG Group
insofar as it is known or reasonably available to Texas Utilities, Texas
Utilities is not currently affiliated with the TEG Group and the TEG Group has
not to date permitted access by Texas Utilities to the TEG Group's books and
records. The TEG Group has provided Texas Utilities with limited balance sheet
information in response to data requests. Therefore, only limited information
concerning the TEG Group which has not been made public is available to Texas
Utilities. Although Texas Utilities has no knowledge that would indicate that
information relating to the TEG Group contained or incorporated by reference in
this Offer Document in reliance upon publicly available information or in
response to data requests are inaccurate or incomplete, Texas Utilities was not
involved in the preparation of such information and statements and, for the
foregoing reasons, is not in a position to verify any such information or
statements. Accordingly, Texas Utilities takes no responsibility for the
accuracy of such information or statements.
 
               PRO FORMA FINANCIAL INFORMATION OF TEXAS UTILITIES
 
     Texas Utilities' financial information for the year ended 31 December 1997
has been combined with the financial information for the TEG Group's Businesses
to be Acquired. The Energy Group publishes its consolidated financial statements
based on United Kingdom generally accepted accounting principles (UK GAAP)
denominated in pounds sterling. The Energy Group has a 31 March fiscal year.
Public financial information of The Energy Group for the period ended 31
December 1997 is not in sufficient detail to allow separation of Peabody's
financial information. Therefore, The Energy Group's semi-annual financial
statements as of 30 September 1997, and for the six months then ended, which are
more complete, have been combined with its statement of income for the six
months ended 31 March 1997, and have been used for the purpose of presenting pro
forma financial information. The Acquisition will be treated as a purchase for
accounting purposes. The purchase accounting adjustments contained herein are
preliminary and represent estimates based on information available to Texas
Utilities. A final determination of the required purchase accounting adjustments
cannot be made at this time; following the Acquisition, a determination of the
fair value of assets acquired and liabilities assumed will be made.
 
     The following unaudited pro forma financial statements assume 100%
acquisition of the TEG Group's Businesses to be Acquired following the Peabody
Sale and further assume that 10% of The Energy Group ordinary shares are
exchanged for Texas Utilities shares. The unaudited condensed pro forma balance
sheet as of 31 December 1997 is presented as if the Acquisition had occurred on
that date. The unaudited pro forma statement of income for the year ended 31
December 1997 assumes that the Acquisition and Peabody Sale occurred at the
beginning of the year.
 
     The unaudited pro forma financial statements should be read in conjunction
with the historical financial statements of Texas Utilities and The Energy Group
and "Management's Discussion and Analysis of Financial Condition and Results of
Operations" of Texas Utilities and The Energy Group incorporated by reference or
included herein and "Pro Forma Financial Information of the TEG Group's
Businesses to be Acquired" included elsewhere herein. The unaudited condensed
pro forma statements of income are not necessarily indicative of the financial
results that would have occurred had the above-described events been consummated
on the indicated dates, nor are they necessarily indicative of future financial
results.
 
     Amounts denominated in UK pounds sterling are translated to US dollars at
the rate of L1=$1.64, which was the exchange rate at 30 September 1997 and the
average exchange rate for the year then ended.

               NOTES TO UNAUDITED PRO FORMA FINANCIAL STATEMENTS
 
(a)  On August 5, 1997 Texas Utilities completed the acquisition of ENSERCH and
     on November 21, 1997 Texas Utilities completed the acquisition of LCC.
     These acquisitions were accounted for as purchase business combinations;
     accordingly, the assets and liabilities of the acquired companies as of the
     acquisition dates were adjusted to fair value and the results of operations
     of such companies were included in Texas Utilities' consolidated statement
     of income from the date of acquisition. This adjustment assumes that the
     acquisitions of ENSERCH and LCC were made at the beginning of the year and
     consists of such companies' operations for the period from January 1, 1997
     to date of acquisition, including amortization of goodwill and purchase
     accounting adjustments.
 
     In 1997, Texas Utilities reacquired 4,015,000 shares of its common stock
     for $148.8 million. In the unaudited condensed pro forma statement of
     income, these share repurchases have been treated as if they had occurred
     at the beginning of the year; accordingly, average shares outstanding have
     been reduced and pro forma interest expense on the purchase price from
     January 1, 1997 to the repurchase date of $7 million, pre-tax has been
     included.
 
     The impact on the pro forma statement of income of the ENSERCH and LCC
     acquisitions and share repurchase is as follows (in millions, except
     shares):

     The Energy Group's annual interest requirement on its debt outstanding at
     30 September 1997 is L176 million or $288 million; some $23 million greater
     than interest expense incurred by The Energy Group's Businesses to be
     Acquired.
 
     Interest on the present value of commitments, obligations and contracts is
     $47 million for the year, including the impact of non-deductible interest
     for tax purposes.
 
     The total pro forma increase to interest and other charges is $429 million.
 
(g)  A final determination of the required purchase accounting adjustments
     cannot be made at this time; following the Acquisition, a determination of
     the fair value and tax basis of assets acquired and liabilities assumed
     will be made. The earnings results will vary from the pro forma earnings
     shown.
 
     Estimated costs to be incurred by Texas Utilities and The Energy Group as a
     result of the Acquisition and Peabody Sale have been excluded from the
     Unaudited Pro Forma Statements of Income. The unaudited pro forma statement
     of income does not reflect any operating efficiencies and annual cost
     savings Texas Utilities may achieve as a result of the Acquisition.
 
(h)  Represents reversal of certain operating expenses recorded by The TEG

                        PRO FORMA FINANCIAL INFORMATION
 
                  OF THE TEG GROUP'S BUSINESSES TO BE ACQUIRED
 
The Energy Group publishes its financial statements based on United Kingdom
generally accepted accounting principles (UK GAAP) denominated in pounds
sterling. The Energy Group has a 31 March fiscal year end. Public financial
information of The Energy Group for the period ended 31 December 1997 is not in
sufficient detail to allow separation of Peabody's financial information.
Therefore, The Energy Group's semi-annual financial statements as of 30
September 1997 and for the six months then ended, which are more complete, have
been combined with its statement of income for the six months ended 31 March
1997, and have been used for the purpose of presenting pro forma financial
information.
 
The following unaudited condensed pro forma financial statements give effect to
adjustments to convert The Energy Group's financial statements to the basis of
United States generally accepted accounting principles (US GAAP) and to the
Peabody Sale. The financial information for the resulting businesses to be
acquired in the Acquisition is converted to US dollars for purposes of combining
with Texas Utilities' financial information. Amounts denominated in UK pounds
sterling are translated to US dollars at the rate of L1 = $1.64, which was the
exchange rate at 30 September 1997 and the average exchange rate for the year
then ended. The unaudited condensed pro forma balance sheet as of 30 September
1997 is presented as if the Peabody Sale had occurred on that date. The
unaudited condensed pro forma statement of income for the year ended 30
September 1997 is presented as if the Peabody Sale had occurred at the beginning
of the period.
 
The unaudited pro forma financial statements are based on the assumptions set
forth in the accompanying notes and should be read in conjunction with the
historical financial statements of The Energy Group and "Management's Discussion
and Analysis of Financial Condition and Results of Operations" of The Energy
Group included in Appendix IV hereto. The unaudited pro forma statement of
income is not necessarily indicative of the financial results that would have
occurred had the Peabody Sale been consummated on the indicated dates, nor are
they necessarily indicative of future financial results.

     *The first dividend declared by The Energy Group, subsequent to its
demerger from Hanson, in respect of the period 1 January 1997 to 31 March 1997,
being 5.5p (net) per ordinary share. For the purposes of the above table, the
net dividend in respect of that period has been multiplied by 4, to reflect the
fact that this payment was stated to represent one quarter of the dividend which
the directors expected would have been paid for the year ended 31 March 1997 if
the company's ordinary shares had been listed throughout the year with the
capital structure resulting from the demerger, grossed up by a factor of 100/80.
 
     **Calculated by multiplying the dividends paid per share of Texas Utilities
Common Stock by an assumed exchange ratio of 0.350 New Texas Utilities Shares
for each Energy Group Share and 1.400 shares of New Texas Utilities Shares for
each Energy Group ADS. Dividends per equivalent Energy Group Share have been
converted from US dollars to pounds sterling at an assumed exchange rate of
$1.645 per L1.
 
     Texas Utilities declared common stock dividends payable in cash in each
year since its incorporation in 1945. In February 1998, Texas Utilities declared
a regular quarterly dividend of 55 cents per share payable 1 April 1998 to
shareholders of record on 6 March 1998. Holders of Energy Group Securities who
receive Texas Utilities Common Stock in connection with the Texas Utilities
Offer will not be entitled to this dividend or any other dividend subsequently
declared with a record date prior to the date of issuance of the relevant New
Texas Utilities Shares.

6  MATERIAL CONTRACTS
 
(a) The following contracts, not being contracts entered into in the ordinary
    course of business, have been entered into by Texas Utilities and its
    subsidiaries, including TU Acquisitions, since 26 January 1996
 
                                     VIII-81
<PAGE>   390
 
(being two years prior to the commencement of the offer period in relation to
The Energy Group) and are or may be material:
 
(i)    the financing arrangements described in paragraph 8 below;
 
(ii)   an Amended and Restated Agreement and Plan of Merger, dated as of 13
       April 1996, by and among Texas Utilities Company, TUC Holding Company and
       ENSERCH pursuant to which Texas Utilities issued approximately $550
       million of its common stock to ENSERCH stockholders in a stock for stock
       transaction;
 
(iii)  an Agreement and Plan of Merger, dated as of 23 August 1997 between Texas
       Utilities and LCC pursuant to which Texas Utilities issued approximately
       8.7 million shares of Texas Utilities Common Stock to LCC stockholders in
       a stock for stock transaction and approximately $31 million of LCC's
       long-term debt remains outstanding; and
 
(iv)   on 1 March 1998, Texas Utilities entered into an agreement with Lehman
       Merchant relating to the Peabody Sale. This agreement provides for the
       parties to make certain payments to each other to reflect the change in
       the net assets of the Peabody Coal Business as shown in the
       post-completion balance sheet and contains other payment obligations of
       Texas Utilities in certain circumstances (including commitment fees in
       relation to the finance required by Lehman Merchant and P & L Coal
       Holdings Corporation, a Delaware corporation (the "Acquisition Entity")
       for the Peabody Sale, which are payable in certain circumstances). Lehman
       Merchant agrees to procure that the Acquisition Entity complies with its
       obligations under the Peabody Sale Agreement (summarised below). Lehman
       Merchant also agrees to provide financing of the Acquisition Entity and
       to cause it to have equity which financing and equity will be sufficient
       to pay the purchase price of the Peabody Coal Business. This agreement
       provides for the separation of the Peabody Coal Business from the
       retained business of The Energy Group (although The Energy Group will
       continue after completion to guarantee and will give credit support (to
       the extent required) in respect of certain existing debt of Citizens
       Power, in an amount not to exceed US$300,000,000) and apportions certain
       pre-existing liabilities. It provides that the Acquisition Entity will
       indemnify Texas Utilities from the date of completion with regard to
       claims, demands, suits and liabilities of any kind relating to (i) the
       Peabody Coal Business and the past, present and future activities of
       those companies conducting the Peabody Coal Business; and (ii) any
       environmental and certain other legacy claims or liabilities relating to
       activities or operations prior to such date of Peabody Investments, Inc.
       or Peabody Global Investments, Inc. or any of their respective
       subsidiaries or predecessors. In addition, Texas Utilities agrees to
       cause The Energy Group to indemnify Lehman Merchant and the Acquisition
       Entity against all claims, demand, suits and liabilities of any kind
       relating to The Energy Group and its retained subsidiaries or affiliates.
 
       As a person deemed to be acting in concert with Texas Utilities pursuant
       to the provisions of the City Code, Lehman Merchant has given certain
       undertakings to Texas Utilities. Lehman Merchant has agreed that neither
       it nor any subsidiary will directly or indirectly (whether itself or
       through persons acting in concert, as defined for the purposes of the
       City Code) be involved in: (a) acquiring or seeking to acquire an
       interest (as defined in Part VI of the Companies Act) in the share
       capital (as defined) of The Energy Group; (b) announcing or making a
       general offer for the share capital of The Energy Group; (c) announcing
       or taking any step or action which under the City Code or otherwise would
       require the announcement of any proposals for any takeover, merger,
       consolidation, share exchange or similar transaction involving the
       securities of The Energy Group; or (d) taking any step or action which
       might give rise to a breach of Rule 4 of the City Code (which prohibits
       certain dealings during an offer period) or any obligation on any person
       under the City Code or otherwise: (i) to make any offer to acquire all or
       part of the share capital of The Energy Group; or (ii) to increase,
       revise, or vary the Texas Utilities Offer. These undertakings will
       continue in full force and effect for so long as Lehman Merchant and
       Texas Utilities are regarded by the Panel as acting in concert as regards
       The Energy Group.
 
                                     VIII-82

        Texas Utilities has agreed that it will not, without Lehman Merchant's
        consent, change the terms and conditions of the Texas Utilities Offer in
        a manner that could reasonably be expected to materially and adversely
        affect Lehman Merchant, the Peabody Coal Business, the purchase of the
        relevant shares by the Acquisition Entity or the financing thereof
        (with, subject as set out below, it being agreed that this shall not
        restrict the waiver of any Conditions to the Texas Utilities Offer
        and/or an increase to the Texas Utilities Offer and/or a revision or
        amendment of the Texas Utilities Offer so as to include a share
        alternative). If Lehman Merchant can demonstrate that a matter or
        circumstance which could rise to a right to invoke a Condition is (a) a
        matter or circumstance which Lehman Merchant discovers after 1 March
        1998; (b) a matter or circumstance which could reasonably be expected to
        materially and adversely affect the Peabody Coal Business or the
        purchase of the relevant shares by the Acquisition Entity or the
        financing thereof; and (c) a matter or circumstance which is of material
        significance in the context of the Texas Utilities Offer, Texas
        Utilities agrees to procure that TU Acquisitions will not waive any
        relevant Condition(s) of the Texas Utilities Offer without the prior
        consent of Lehman Merchant. Notwithstanding the foregoing, neither Texas
        Utilities nor TU Acquisitions are required to invoke any Condition of
        the Texas Utilities Offer so as to cause the Texas Utilities Offer to
        lapse if the Panel does not agree that any such Condition may be invoked
        and/or that the Texas Utilities Offer may lapse as a result of failure
        to waive any such Condition provided that Texas Utilities agrees to give
        Lehman Merchant all reasonable opportunity and reasonable assistance in
        making representations to the Panel that in such circumstances the
        Conditions may be invoked so as to cause the Texas Utilities Offer to
        lapse. In the absence of Panel agreement, no member of the Texas
        Utilities Group shall have any obligation or liability to Lehman
        Merchant on this issue. Texas Utilities has also agreed not to extend
        the Texas Utilities Offer without Lehman Merchant's written consent to
        an expiration date beyond four months from the announcement thereof,
        unless the Texas Utilities Offer has become or is declared to be
        unconditional.
 
     (v)In a separate agreement with The Energy Group, Texas Utilities has
        agreed that, in the event that the conditions set out below are
        fulfilled, it will pay the sum of US$50 million in cash to The Energy
        Group. The conditions referred to are: (a) the conditions to the Peabody
        Sale Agreement referred to in sub-paragraphs (b), (c) and (d) of
        paragraph 10 of the letter from Lehman Brothers and Merrill Lynch having
        been satisfied or waived but the condition set out in sub-paragraph (e)
        of that paragraph not remaining satisfied; (b) the Texas Utilities Offer
        lapsing or being withdrawn, having not become or been declared
        unconditional in all respects in circumstances in which Condition (b)
        set out in Part A of Appendix I to this document is not fulfilled,
        Conditions (c) to (m) have been fulfilled, remain satisfied and/or have
        been waived and Condition (a) would, but for the second proviso
        contained in that Condition, be capable of being declared satisfied; (c)
        the Renewed PacifiCorp Offer (and any revision thereof) lapsing or being
        withdrawn, having not become or been declared unconditional in all
        respects; and (d) on or prior to 2 March 1999 neither Texas Utilities
        nor PacifiCorp nor any associate of Texas Utilities or PacifiCorp (as
        the case may be) having acquired control (as defined in Section 416 of
        the Income and Corporation Taxes Act 1988) of The Energy Group pursuant
        to a general offer at a cash price (or, if such offer is not a cash
        offer, at a value of the consideration offered, on the date of
        announcement of such offer) equal to or in excess of 765p per Energy
        Group Share.
 
(b)  In addition, on 2 March 1998 the Peabody Sale Agreement was entered into
     between The Energy Group and the "Acquisition Entity". It is conditional on
     fulfillment of the conditions set out in paragraph 10 of the letter from
     Lehman Brothers and Merrill Lynch. The total consideration payable in
     respect of the sale of the Peabody Coal Business is approximately $2.3
     billion, payable in cash on completion of the Peabody Sale Agreement, plus
     the assumption of debt. Completion is expected to take place on the same
     day that the Texas Utilities Offer becomes or is declared unconditional in
     all respects. Each of the parties to the Peabody Sale Agreement gives
     certain warranties concerning, principally, due execution of the Peabody
     Sale Agreement and The Energy Group in addition warrants title to the
     various shares to be transferred to the Acquisition Entity. The Energy
     Group gives certain undertakings to the Acquisition Entity concerning the
     conduct of the Peabody Coal Business prior to completion of the Peabody
     Sale; it is
                                     VIII-83
<PAGE>   392
 
     agreed that the relevant companies will be directed to conduct their
     business in the ordinary and usual course as currently carried on by such
     companies and their subsidiaries and that no action will be taken with
     regard to such companies or their respective subsidiaries which would, if
     such companies and their subsidiaries taken as a whole were an offeree
     company subject to the City Code, amount to an action requiring the
     approval of shareholders in general meeting under Rule 21 of the City Code
     (namely, issuing any authorised but unissued shares, issuing or granting
     options in respect of any unissued shares, creating or issuing securities
     with rights of conversion into shares, agreeing to sell or acquire assets
     of a material amount and entering into contracts other than in the ordinary
     course of business). By a letter dated 2 March 1998, Texas Utilities agreed
     to indemnify and hold harmless The Energy Group and certain connected
     persons, including directors of The Energy Group, from and against, inter
     alia, claims relating to or arising in connection with the Peabody Sale
     Agreement, subject to certain exceptions.
 
7  BACKGROUND TO AND REASONS FOR THE TEXAS UTILITIES OFFER
 
BACKGROUND TO THE TEXAS UTILITIES OFFER
 
In December 1997, Texas Utilities was contacted by representatives of Lehman
Brothers to generally discuss the possibility of an acquisition involving The
Energy Group. In those discussions, Lehman Brothers indicated that they had
identified a potential purchaser of the Peabody Coal Business (which includes
Citizens Power).
 
In January 1998, Texas Utilities engaged Lehman Brothers and Merrill Lynch as
its financial advisors with respect to evaluating any potential transaction
involving The Energy Group. Lehman Brothers advised at that time that Lehman
Merchant was the potential purchaser of the Peabody Coal Business.
 
On 19 January 1998, Erle A. Nye, Chairman and Chief Executive of Texas
Utilities, contacted Derek Bonham, Chairman of The Energy Group to indicate
Texas Utilities' interest in exploring a possible acquisition of The Energy
Group. Mr Nye indicated that a team comprised of Texas Utilities'
representatives as well as legal and financial advisors would be arriving in
London to begin conducting due diligence activities.
 
On 23 January 1998, H. Jarrell Gibbs, Vice-Chairman of Texas Utilities met with
Mr Bonham to discuss further Texas Utilities' interest in exploring a potential
acquisition of The Energy Group. Mr Gibbs and Mr Bonham discussed the background
of the Texas Utilities Group and the strategic advantages of a possible
acquisition as well as the possibility of the sale of the Peabody Coal Business
to a third party. Mr Gibbs requested access to information and representatives
of The Energy Group to begin its due diligence review.
 
On 23 January 1998, a confidentiality agreement was executed between the
parties, establishing the terms under which further discussions would proceed.
Thereafter, Texas Utilities engaged in a due diligence review of The Energy
Group and conducted negotiations with Lehman Merchant regarding their purchase
of the Peabody Coal Business.
 
On 23 January 1998, Texas Utilities held a meeting of the Business Development
Committee of its Board of Directors to present its preliminary views on a
possible acquisition of The Energy Group.
 
On 27 January 1998, Mr Gibbs, Robert S. Shapard, Vice President and Treasurer of
Texas Utilities, and representatives of Texas Utilities' advisors met with Eric
E. Anstee, Financial Director of The Energy Group, and several of his
colleagues. At this meeting, Mr Anstee presented financial and operational
information on The Energy Group.
 
On 30 January 1998, Mr Gibbs, Mr Shapard and Robert A. Wooldridge, counsel to
Texas Utilities, met with John F. Devaney, Chief Executive of Eastern, to
introduce Texas Utilities to Mr Devaney and to further discuss The Energy Group
but did not have substantive discussions relating to a potential transaction.
 
On 5 February 1998, Mr Gibbs again met with Mr Bonham to present Texas
Utilities' views as to possible structure of a transaction and indicated that
Texas Utilities remained interested in The Energy Group following the Renewed
PacifiCorp Offer.
 
On 12 February 1998, Mr Gibbs met with Mr Anstee to further discuss their
respective companies but did not have substantive discussions relating to a
potential transaction.
 
                                     VIII-84
<PAGE>   393
 
On 13 February 1998, Mr Gibbs again met with Mr Devaney to further discuss
Eastern.
 
On 19 and 20 February 1998, the Board of Directors of Texas Utilities met.
Senior executives of Texas Utilities and the company's financial and legal
advisers discussed in detail all aspects of a proposed transaction and reported
on the due diligence examination of The Energy Group. Thereupon, the Board of
Directors unanimously approved a resolution granting company management the
authority to make an offer.
 
On 23 February 1998, Mr Nye met with Mr Bonham to discuss a possible acquisition
of The Energy Group. Mr Nye informed Mr Bonham on the actions taken by the Texas
Utilities Board of Directors and other activities to date in relation to the
possible acquisition. They also discussed the strategic advantages of a possible
acquisition and discussed a range of values for The Energy Group.
 
On 25 February 1998, Mr Nye met with Mr Devaney and on 26 February, Mr Nye and
Mr Gibbs met with Mr Anstee and in both meetings the parties discussed their
respective companies and various management and corporate matters.
 
On 1 March 1998, Texas Utilities completed negotiations with Lehman Merchant
regarding the acquisition of the Peabody Coal Business from The Energy Group.
 
On 1 March 1998, Mr Nye again met with Mr Bonham to present an offer at a price
of 810 pence per Energy Group Share.
 
On 2 March 1998, the Boards of Texas Utilities and the Energy Group announced
the terms of a recommended offer at a price of 810 pence per Energy Group Share.
On 3 March 1998 Texas Utilities announced an increased offer at a price of 840
pence per Energy Group Share in response to the Increased PacifiCorp Offer.
 
REASONS FOR THE TEXAS UTILITIES OFFER
 
Texas Utilities has formulated a strategy to position itself to thrive in a more
competitive environment and to identify new business investments that both
capitalise on its core competencies and are complementary to its existing
portfolio of businesses in order to grow earnings, broaden its markets beyond
the traditional service areas and expand customer services.
 
The acquisition of The Energy Group is further confirmation of Texas Utilities'
commitment to this strategy. The Energy Group comprises a unique blend of
electricity generation, supply and distribution assets, combined with strengths
in natural gas and energy trading. Texas Utilities believes that the highly
complementary nature of these activities to those of Texas Utilities, combined
with The Energy Group's experience of operating within a deregulating market,
will enable the enlarged group to capitalise upon the sharing of the expertise
and best practices that reside within the two groups in each of these areas.
 
Texas Utilities expects the transaction to be earnings and cash flow enhancing
in the first complete year following completion of the Acquisition and
thereafter (prior to considering any synergy or other benefits that the
transaction may give rise to). This statement should not be interpreted to mean
that the future earnings per share of Texas Utilities, as enlarged by the
acquisition of The Energy Group, will necessarily be greater than the historical
published earnings per share of Texas Utilities.
 
8  FINANCING ARRANGEMENTS
 
TU Acquisitions estimates that the total amount of financing necessary to
purchase, pursuant to the Texas Utilities Offer and the compulsory acquisition
procedures referred to in paragraph 9 below or otherwise, all Energy Group
Securities that are outstanding, and to pay all associated fees costs and
expenses, is approximately L4,594 million. Financing arrangements have been
entered into, directly or indirectly, by the indirect holding company of TU
Acquisitions, TU Finance (No. 1) Limited ("TUF"), and by Texas Utilities itself
which provide committed finance which is considered to be sufficient for such
purposes and TUF and Texas Utilities have agreed to pass on to TU Acquisitions,
by means of a combination of subscribing for shares and perpetual loan notes in
TU Acquisitions, and by making intercompany loans to TU Acquisitions, the
 
                                     VIII-85
<PAGE>   394
 
proceeds of borrowings to be made by TUF and Texas Utilities under those
arrangements. The principal terms of those arrangements are as follows:
 
TUF ARRANGEMENTS
 
TUF has entered into a facilities agreement for L3,625 million credit facilities
dated 2 March 1998, as amended by an Amendment Agreement dated 3 March 1998 (the
"TUF Credit Agreement"), arranged by Chase Manhattan plc, Lehman Brothers
International and Merrill Lynch Capital Corporation (the "TUF Arrangers"), under
which The Chase Manhattan Bank, Lehman Commercial Paper Inc. and Merrill Lynch
Capital Corporation are the Underwriters (committing on a several one-third
basis to provide the entire facilities) and Chase Manhattan International
Limited is Facility Agent and Security Agent (together the "Agent"). Pursuant to
the TUF Credit Agreement, TUF is entitled to borrow up to L2,925 million by way
of acquisition and interim advances for the purpose of financing the acquisition
of Energy Group Securities and associated purposes and TUF and/or any permitted
borrower (which includes the members of the TEG Group) are entitled to borrow up
to L700 million by way of revolving advances for the purpose of refinancing
borrowings of the TEG Group and for general corporate purposes (subject to L250
million of that amount being made available under the REC Facility Agreement as
referred to below).
 
Pursuant to the provisions of the TUF Credit Agreement, on the date the Texas
Utilities Offer becomes or is declared unconditional, a standalone L250 million
revolving credit facility will be granted to Eastern (the "REC Facility
Agreement"). The REC Facility Agreement will not be cross-defaulted to the TUF
Credit Agreement and there will be no cross-guarantee given by Eastern or any of
its subsidiaries in respect of the obligations of any of the borrowers under the
TUF Credit Agreement. Advances under the REC Facility Agreement will bear
interest at the aggregate of the applicable margin, the mandatory liquid asset
cost and the relevant London interbank offered rate as determined in accordance
with normal provisions for large syndicated facilities ("LIBOR"). The applicable
margin thereunder is 0.50 per cent.
 
All the advances under the TUF Credit Agreement bear interest at the aggregate
of the applicable margin, the mandatory liquid asset costs and LIBOR. The
applicable margin is initially 1.25 per cent. per annum until the interim
advances have been repaid and the leverage ratio is between 65 per cent. and 60
per cent. when the rate reduces to 1 per cent. and if the leverage ratio reduces
to below 60 per cent. the rate will further reduce to 0.75 per cent.
 
Of the total L2,925 million available to finance the acquisition of Energy Group
Securities, the first L1,775 million is to be drawn by way of acquisition
advances and thereafter the remainder by way of interim advances. The interim
advances are repayable within ten months of the date of the TUF Credit
Agreement. An additional mandatory prepayment will be repaid out of or by
reference to the proceeds of the Peabody Sale, which are to be upstreamed,
directly or indirectly, to TU Acquisitions and to TUF. The methods available to
TUF and TU Acquisitions in order to upstream such proceeds include any one or
more of intercompany loans out of the TEG Group in accordance with sections 155
to 158 of the Companies Act or the purchase of own shares of The Energy Group,
and TUF and TU Acquisitions have agreed to take the steps necessary to lawfully
upstream such proceeds as soon as practicable after the Texas Utilities Offer
becomes or is declared unconditional.
 
The acquisition and interim facilities contain an alternative for financing
payments due under the Loan Notes, either by means of the facilities continuing
for five years to be available for that purpose or by means of a drawing being
made ten months after the date of the TUF Credit Agreement and retained in a
blocked account for application in meeting such payments.
 
Of the remaining acquisition advances, L600 million is repayable on the second
anniversary of the date of the TUF Credit Agreement (such repayment subject to
reduction for previously applied repayments other than repayments of the interim
advances) and the balance is repayable on the fifth anniversary.
 
The availability of the advances is subject to a number of conditions precedent,
and the majority of these have already been acknowledged by the Agent as
fulfilled. The conditions precedent which had not been fulfilled at the date of
this Offer Document were confined to matters which inevitably would not be
fulfilled until a later
 
                                     VIII-86
<PAGE>   395
 
stage and which include conditions: that the funds to be contributed by Texas
Utilities to TU Acquisitions and TUF have been duly paid; a confirmation that
the terms and conditions of the Texas Utilities Offer have not been waived,
amended, varied or declared to be satisfied other than in accordance with the
terms of the TUF Credit Agreement; that the Office of Fair Trading has indicated
that it is not the intention of the Secretary of State for Trade and Industry to
refer the Acquisition to the Monopolies and Mergers Commission; confirmation
that the Peabody Sale Agreement has become unconditional save for conditions
relating to the Texas Utilities Offer becoming unconditional (and that the
consideration has been received in escrow by the TEG Group); and confirmation
that the Texas Utilities Offer has become or has been declared unconditional in
all respects.
 
There is a covenant that TU Acquisitions will comply with Rule 10 of the City
Code, which requires, in summary, that it shall not declare the Texas Utilities
Offer unconditional unless TU Acquisitions has acquired or agreed to acquire
Energy Group Shares carrying in aggregate more than 50 per cent. of the voting
rights exercisable at general meetings of The Energy Group. Apart from that
covenant, which does no more than incorporate into the TUF Credit Agreement a
provision which is applicable to all offers governed by the City Code, there are
no covenants or conditions precedent or other provisions which limit the
flexibility of TU Acquisitions to declare the Texas Utilities Offer
unconditional at any level of acceptances which it may in its discretion decide.
 
Advances under the TUF Credit Agreement for the purpose of acquiring Energy
Group Securities during the Certain Funds Period (which, if the Texas Utilities
Offer has not previously lapsed or been withdrawn, covers the period through to
the fifteenth day after the last closing date of the Texas Utilities Offer
(extended if necessary to include any further period during which the compulsory
acquisition procedures referred to in paragraph 9 below are being implemented)
but subject to a final cut-off seven months after the date of the Texas
Utilities Offer) enjoy "certain funds" protection. This means that the only
condition to the lending banks' obligations to make such advances during such
period, once the conditions precedent referred to in the preceding paragraph
have been satisfied or waived, is that no Major Default has occurred; for these
purposes a Major Default is an insolvency of TU Acquisitions or TUF or TU
Finance (No. 2) Limited, which is the intermediate holding company of TU
Acquisitions (which is also a subsidiary of TUF) (which are referred to together
in this section as the "Relevant Offeror Companies"), an amendment of the
Peabody Sale Agreement without the lending banks' consent, a breach of the
covenants given in respect of the conduct of the Texas Utilities Offer, a breach
of representation concerning the validity of the TUF Credit Agreement, a default
which is within the Relevant Offeror Companies' power to remedy within seven
days but which is not remedied within seven days after notice and, in respect of
advances to purchase under the compulsory acquisition procedures referred to in
paragraph 9 below only, insolvency of certain key TEG Group companies.
 
The TUF Credit Agreement also includes the following provisions:
 
Representations and warranties as to matters that are normal in such context,
but the only matters represented which would have any effect during the Certain
Funds Period relate to the Relevant Offeror Companies and in particular to
corporate standing and powers, legality and validity of obligations and the
companies being clean companies. The representations given in respect of the TEG
Group do not apply until 120 days after the date the Texas Utilities Offer
becomes or is declared wholly unconditional (the "Unconditional Date").
 
Financial undertakings to maintain a ratio of earnings before interest, tax,
depreciation and amortisation to net interest costs of not less than 2:1 and a
leverage ratio (expressing borrowings of the group as a percentage of total
capitalisation) of not more than 70 per cent. until 30 September 2000 and 65 per
cent. thereafter. Such undertakings are not relevant to the certain funds
protection.
 
The covenants given in respect of the Texas Utilities Offer are: to comply with
the City Code and applicable law; to keep the Facility Agent informed of
progress; not declare the Offer unconditional at a level of acceptances below
that required by Rule 10 of the City Code; not without the consent of the TUF
Arrangers acting on the instructions of a 66 2/3 per cent. (by value) majority
of the lending banks to waive, amend, or agree or decide not to enforce
Conditions (b) and (c); not without the consent of the TUF Arrangers acting on
the instructions of a 66 2/3 per cent. (by value) majority of the lending banks
(such consent not to be unreasonably withheld or delayed) to waive, amend (save
for an extension of the offer period), or agree or
                                     VIII-87
<PAGE>   396
 
decide not to invoke any other material Conditions, provided that there shall be
no breach of this provision if directions of the Panel are being followed; to
lapse the Texas Utilities Offer if grounds to do so exist and the Panel agrees
to such lapse if in the reasonable opinion of the above majority of lending
banks the same would have a material and adverse effect on the ability of the
borrowers to comply with their material obligations under the TUF Credit
Agreement; to lapse the Texas Utilities Offer if grounds to do so exist and the
Panel agrees to such lapse if undertakings and assurances as are referred to in
Condition (e) are required or modifications to the Licences (being licenses
granted under section 6 of the Electricity Act 1989 to carry on distribution,
supply and generation of electricity and under section 7 of the Gas Act of 1986)
as are referred to in Condition (d) are required or any terms are proposed for
any other authorisation or determination which in the reasonable opinion of the
above majority of lending banks would have a material and adverse affect on the
ability of the borrowers to comply with their material obligations under the TUF
Credit Agreement; the important proviso is that the lending banks cannot require
the Texas Utilities Offer to be lapsed if the proposed modifications to the said
Licences or the terms of the proposed undertakings or assurances are no more
onerous than those set out and required by the DGES from PacifiCorp in
accordance with the terms of the Monopolies and Mergers Commission Report into
the Original PacifiCorp Offer for The Energy Group published on 19 December
1997.
 
The TUF Credit Agreement also contains a covenant to procure that companies in
the TEG Group shall give guarantees in respect of the indebtedness of the
borrowers thereunder save where: the same would be unlawful or contrary to
regulation and it is not legally possible for the same to be rendered lawful;
the same would reasonably be expected to breach a condition of the Licences and
as a result would entitle the Secretary of State for Trade and Industry to
revoke or withdraw such Licences or amend the Licences in a manner which would
reasonably be expected to have a material adverse effect; the same would cause
the TEG Group's public debt to become repayable or subject to put rights to
similar effect and (either) there is not sufficient headroom in available
facilities to enable it to refinance or, even if there is sufficient headroom,
the financial consequences of refinancing would be so materially adverse
(whether in terms of coupon or otherwise) that it would be unreasonable to
require such refinancing.
 
There are standard negative undertakings, including: a negative pledge to which
there are a number of exceptions including any security on TEG Group assets at
the Unconditional Date; a covenant against borrowing to which there are a number
of exceptions including existing TEG Group borrowings or any refinancing
thereof, new borrowings which do not breach the leverage ratio covenant and only
by The Energy Group itself and after it had given a guarantee, and limited
recourse borrowing of project finance subsidiaries; a disposals covenant to
which there are a number of exceptions including the Peabody Sale, disposals in
the ordinary course of trading, disposals of up to 10 per cent. of gross assets
in any financial year and any other disposal the proceeds of which are used to
repay the facilities; covenants relating to the Licences and to compliance with
the terms thereof; restrictions on the payment of dividends by TUF except to the
extent dividends could be paid without breaching the leverage ratio and only
after TU Acquisitions owns at least 90 per cent. of the Energy Group Securities;
restrictions on changing business of the TEG Group outside the electricity, gas,
water, telecommunications industries (save that up to 10 per cent. of the assets
or revenues of the TEG Group may comprise other businesses); ring-fence
covenants restricting the activities that the Relevant Offeror Companies are
permitted to do; restrictions on acquisitions outside core business except
through limited recourse project finance subsidiaries.
 
No covenant (except the financial undertakings) shall apply to the TEG Group
until the date 120 days after the Unconditional Date but the Relevant Offeror
Companies agree to use their commercially reasonable endeavours to run the TEG
Group as if such covenants did apply.
 
The events of default include: non-payment (subject to a limited three banking
day grace period), breach of undertaking or misrepresentation (both subject to a
limited ability to remedy defaults within 21 days); cross-default of other
borrowed money over a threshold of L20 million; legal process; insolvency events
(including winding-up, administration, receivership and dissolution); change of
control of TU Acquisitions or TUF; cessation of the distribution business or
changes to the regulatory regime that would be reasonably likely to have a
material adverse effect; loss of the Licence or the modification of it that
would be reasonably likely to have a material adverse effect; repeal or
amendment of the Electricity Act 1989 or non-compliance with an
                                     VIII-88
<PAGE>   397
 
order made under that Act which, in either case would be reasonably likely to
have a material adverse effect; Eastern or any of its subsidiaries ceases to be
a party to a pooling and settlement agreement dated 30th March 1990 made between
Eastern and the National Grid Company plc; Eastern or any of its subsidiaries
ceases to be a party to a gas framework agreement dated 1st March 1991 made
between British Gas Transco and Eastern Natural Gas (Retail) Limited and this
would be reasonably likely to have a material adverse effect; illegality or
unlawfulness; change of control of Texas Utilities; waiver or amendment of the
Peabody Sale Agreement without consent.
 
An event of default will not entitle the lending banks to accelerate the
facilities made available under the TUF Credit Agreement or to cancel their
commitments during the Certain Funds Period; the lending banks would only have
that entitlement if a Major Default occurred, as described above. Additionally,
several of the above events are not applied to the TEG Group until 120 days
after the Unconditional Date.
 
The TUF Credit Agreement also contains provisions relating to repayment,
prepayment, cancellation and reductions; fees and expenses; payments and taxes;
accounts and calculations, indemnities; unlawfulness, increased costs, and
alternative interest rates; assignment, substitution and lending offices,
clauses relating to the Agent and notices.
 
TEXAS UTILITIES ARRANGEMENTS
 
Texas Utilities together with certain of its subsidiaries (each a "Borrower")
have entered into a 364 Day Competitive Advance and Revolving Credit Facility
Agreement for US$3,600 million credit facilities (the "TU Facility A Agreement")
and a 5 year Competitive Advance and Revolving Credit Facility Agreement (the
"TU Facility B Agreement") for US$1,400 million credit facilities, each dated as
of 2 March 1998, as amended on 3 March 1998, and arranged by Chase Securities
Inc., Lehman Brothers Inc. and Merrill Lynch & Co., under which The Chase
Manhattan Bank, Lehman Brothers Commercial Paper and Merrill Lynch Capital
Corporation are the Underwriters (committing on a several one-third basis to
provide the entire facilities), Chase Bank of Texas, National Association is the
Administrative Agent and The Chase Manhattan Bank is the Competitive Advance
Facility Agent. Texas Utilities has also entered into an interim 364 Day
Competitive Advance and Revolving Credit Facility Agreement (Interim Facility)
dated as of 6 March 1998 with the same Initial Underwriters and Joint Lead
Arrangers as in the TU Facility A Agreement for the purpose of financing the
purchase of Energy Group Shares in the UK market through draws or backstop of
commercial paper issuances. Any draws under such Interim Facility will be repaid
through drawings on the TU Facility A Agreement at or about the time the Texas
Utilities Offer becomes or is declared unconditional in all respects.
 
Pursuant to the TU Facility A Agreement, by way of revolving standby loans (each
a "Standby Loan") and competitive loans pursuant to a bidding procedure (each a
"Competitive Loan"), Texas Utilities is entitled to borrow up to $2,800 million
for the sole purpose of financing or refinancing equity or subordinated loan
advances from Texas Utilities to TUF for the purpose of on loaning to TU
Acquisition to finance the acquisition of Energy Group Securities and each of
the Borrowers are entitled to borrow up to an aggregate $800 million for the
purpose of refinancing certain of their existing borrowings and for working
capital and other corporate purposes, including commercial paper back-up.
 
Borrowings under the TU Facility B Agreement may be applied for refinancing,
working capital and corporate purposes, including borrowings for the purpose of
paying certain expenses incurred in connection with the Texas Utilities Offer.
 
Each Standby Loan at the option of the Borrower will bear interest at either the
aggregate of the applicable margin and LIBOR (in which case a "Eurodollar
Standby Loan") or at the aggregate of the Alternate Base Rate (being a rate
equal to the greatest of (a) the Federal Funds Effective Rate plus 0.5 per
cent., (b) the Base CD Rate plus 1 per cent. and (c) the Prime Rate publicly
announced by the Chase Manhattan Bank) and the applicable margin (in each case
an "ABR Loan").
 
Each Competitive Loan, at the option of the Borrower, will bear interest at
either the aggregate of the competitive bid margin and LIBOR (in which case a
"Eurodollar Competitive Loan" and, together with the
 
                                     VIII-89
<PAGE>   398
 
Eurodollar Standby Loans, the "Eurodollar Loans") or at the fixed rate specified
by the chosen lender in its competitive bid (in which case a "Fixed Rate Loan").
 
The applicable margin for the first six months of the facility is 0% for ABR
Loans, and 1.05% for Eurodollar Loans. After six months the margin varies
according to the debt ratings assigned by S&P and Moody's to Texas Utilities
subject to a maximum for Eurodollar Loans of 1.25% and for ABR Loans of 0.25%.
 
Each loan is repayable on the earlier of the last day of the interest period
applicable to it and the maturity date. The maturity date will be the 364th
calendar day after execution of the TU Facility A Agreement unless, provided no
default has occurred and is continuing, the Borrowers elect to extend for
another 364 days.
 
The interest period in respect of Eurodollar Loans shall be 1, 2, 3 or 6 months
except that, until general syndication is completed, it shall be 1 month or such
other period as the arrangers and Texas Utilities shall agree as being necessary
to effect the transfer of participations following syndication. In respect of
ABR Loans the interest period will commence on the date of the borrowing and end
on the earliest of (i) the last day of the next succeeding quarter, (ii) the
maturity date and (iii) the date of repayment or prepayment in accordance with
the provisions of the TU Facility A Agreement. For a Fixed Rate Loan, the
interest period shall commence on the date of the borrowing and end on the date
specified in the competitive bid, being not less than 7 days nor more than 360
days.
 
The availability of the advances is subject to a number of conditions precedent,
and the majority of these have already been acknowledged by the Competitive
Advance Facility Agent as fulfilled. The outstanding conditions precedent
include satisfaction of the conditions precedent to the advance of funds for the
acquisition of Energy Group Securities under the TUF Credit Facility as
described above and declaration of the Texas Utilities Offer as unconditional.
 
Advances under the facility for the purpose of acquiring Energy Group Securities
during the period of 364 days after its execution (provided the Texas Utilities
Offer is not previously lapsed or withdrawn, and is posted within 28 days of
satisfaction of the conditions precedent) enjoy "certain funds" protection. This
means that the only condition to the Banks' obligations to make such advances
during such period, once the conditions precedent referred to in the preceding
paragraph have been satisfied or waived is that no Major Default has occurred.
Major Defaults are the same as those described with respect to the TUF
arrangements above, applied to the Borrowers.
 
The TU Facility A Agreement also includes the following provisions:
 
Representations and warranties as to matters that are normal in such context but
the only matters represented which would have any effect during the period of
certain funds protection relate only to the Borrowers and in particular to
corporate standing and powers and legality and validity of obligations.
 
Financial undertakings by Texas Utilities to maintain a ratio of earnings before
interest, tax, depreciation and amortisation to net interest costs of not less
than 1.5 to 1 and a leverage ratio (expressing consolidated shareholder's equity
of the group as a percentage of the group's total capitalisation) of not less
than 26 per cent. until 30 June 1999, 30 per cent. from 30 June 1999 until 30
June 2000 and 35 per cent. thereafter. Such undertakings are not relevant to the
certain funds protection.
 
Covenants given by Texas Utilities in respect of the Texas Utilities Offer which
mirror those given by TUF in the TUF Credit Agreement as are detailed above.
 
There are standard negative undertakings, including limitations on liens,
restrictions on certain mergers, consolidations and changing the nature of the
business of Texas Utilities or its subsidiaries.
 
No covenant shall apply to the TEG Group until the date 120 days after the
Unconditional Date but Texas Utilities agrees to use all reasonable endeavours
to cause The Energy Group and all members of the TEG Group to comply with such
covenants on and after the Unconditional Date.
 
The events of default include: non-payment, breach of representations or
warranties; cross-default of other borrowed money subject to a de minimis amount
of US$40 million; legal judgments rendered against Texas Utilities or a
subsidiary in an aggregate amount in excess of US$50 million; insolvency events
(including
                                     VIII-90
<PAGE>   399
 
winding-up, administration, receivership and dissolution); change of control of
Texas Utilities; Texas Utilities not holding all of the stock of TU Electric and
at least 51% of ENSERCH.
 
An event of default will not entitle the lending banks to accelerate the
facilities made available under the TU Facility A Agreement or to cancel their
commitments during the period of certain funds protection; the lending banks
would only have that entitlement if a Major Default occurred. Additionally, the
cross-default is not applied to the TEG Group until 120 days after the
Unconditional Date.
 
The TU Facility A Agreement also contains provisions relating to repayment,
prepayment, cancellation and reductions; fees and expenses; payments and taxes;
accounts and calculations, indemnities; unlawfulness, set-off, increased costs,
and alternative interest rates; assignment, clauses relating to the
Administrative Agent and the Competitive Advance Facility Agent and notices.
 
9  COMPULSORY ACQUISITION
 
If, within four months after the date of this document, as a result of the Texas
Utilities Offer or otherwise, TU Acquisitions acquires or contracts to acquire
Energy Group Shares (including Energy Group Shares represented by Energy Group
ADSs) representing at least 90 per cent. in value of Energy Group Shares
(including Energy Group Shares represented by Energy Group ADSs) to which the
Texas Utilities Offer relates, then (a) TU Acquisitions will be entitled and
intends to effect the compulsory acquisition procedures provided for in sections
428 to 430F of the Companies Act to compel the purchase of any outstanding
Energy Group Shares on the same terms as provided in the Texas Utilities Offer
in accordance with the relevant procedures and time limits described in such
Act, and (b) a holder of Energy Group Shares (including Energy Group Shares
represented by Energy Group ADSs) may require TU Acquisitions to purchase his
Energy Group Shares (including Energy Group Shares represented by Energy Group
ADSs) on the same terms as provided in the Texas Utilities Offer in accordance
with the relevant procedures and time limits described in section 430A of the
Companies Act.
 
If for any reason the above-mentioned compulsory acquisition procedures are not
invoked, TU Acquisitions will evaluate other alternatives to obtain the
remaining Energy Group Shares (including Energy Group Shares represented by
Energy Group ADSs) not purchased pursuant to the Texas Utilities Offer or
otherwise. Such alternatives could include acquiring additional Energy Group
Securities in the open market, in privately negotiated transactions, through
another offer to purchase, by means of a scheme of arrangement under the
Companies Act or otherwise. Any such additional acquisitions could be for a
consideration greater or less than, or equal to, the consideration for Energy
Group Securities under the Texas Utilities Offer. However, under the City Code,
except with the consent of the Panel, TU Acquisitions may not acquire any Energy
Group Securities on better terms than those of the Texas Utilities Offer within
six months of the termination of the Texas Utilities Offer if TU Acquisitions,
together with any persons acting in concert with it (as defined by the City
Code), holds following the Texas Utilities Offer, shares carrying more than 50
per cent. of the voting rights normally exercisable at general meetings of The
Energy Group.
 
Holders of Energy Group Securities do not have appraisal rights as a result of
the Texas Utilities Offer. However, in the event that the compulsory acquisition
procedures referred to above are available to TU Acquisitions, holders of Energy
Group Securities whose Energy Group Securities have not been purchased pursuant
to the Texas Utilities Offer will have certain rights to object under section
430C of the Companies Act.
 
10  CERTAIN CONSEQUENCES OF THE TEXAS UTILITIES OFFER
 
(A) MARKET EFFECT
 
The purchase of Energy Group Securities pursuant to the Texas Utilities Offer
will reduce the number of holders of Energy Group Securities and the number of
the Energy Group Securities that might otherwise trade publicly and, depending
upon the number of Energy Group Securities so purchased, could adversely affect
the liquidity and market value of the remaining Energy Group Securities held by
the public. In addition, Energy Group Shares will cease to be listed on the
London Stock Exchange and Energy Group ADSs will
 
                                     VIII-91
<PAGE>   400
 
cease to be listed on the NYSE if TU Acquisitions completes the compulsory
acquisition procedures referred to in paragraph 9 above. Whether or not TU
Acquisitions is in a position to effect the compulsory acquisition of any
outstanding Energy Group Shares in accordance with the Companies Act as referred
to above, and irrespective of the size of any outstanding minority in The Energy
Group, TU Acquisitions intends to seek to procure, after the Texas Utilities
Offer becomes or is declared unconditional, an application by The Energy Group
to the London Stock Exchange for Energy Group Shares to be delisted and an
application by The Energy Group to the NYSE for Energy Group ADSs to be
delisted.
 
(B) PUBLIC AVAILABILITY OF INFORMATION
 
     In the event that Energy Group Shares continue to be listed on the London
Stock Exchange following the purchase of Energy Group Securities pursuant to the
Texas Utilities Offer, holders of Energy Group Shares who have not tendered
their Energy Group Shares pursuant to the Texas Utilities Offer will continue to
receive the same financial and other information from The Energy Group that The
Energy Group presently is required by the rules of the London Stock Exchange to
send to such holders. If Energy Group Shares are no longer listed on the London
Stock Exchange following the Texas Utilities Offer, The Energy Group would no
longer be required by those rules to make publicly available such financial and
other information.
 
     Energy Group ADSs are currently registered under the Exchange Act.
Registration of such Energy Group ADSs may be terminated upon application of The
Energy Group to the SEC if Energy Group ADSs are neither listed on a national
securities exchange nor held by 300 or more beneficial owners in the US.
Termination of registration of Energy Group ADSs under the Exchange Act would
substantially reduce the information required to be furnished by The Energy
Group to holders of Energy Group ADSs and to the SEC and would make certain
provisions of the Exchange Act, such as the requirements of Rule 13e-3
thereunder with respect to "going private" transactions, no longer applicable to
The Energy Group. Furthermore, "affiliates" of The Energy Group and persons
holding "restricted securities" of The Energy Group may be deprived of the
ability to dispose of such securities pursuant to Rule 144 promulgated under the
Securities Act. If, as a result of the purchase of Energy Group ADSs pursuant to
the Texas Utilities Offer and prior to completing the compulsory acquisition
procedures referred to in paragraph 9 above, The Energy Group is not required to
maintain registration of Energy Group ADSs under the Exchange Act, TU
Acquisitions intends to cause The Energy Group to apply for termination of such
registration. If registration of Energy Group ADSs is not terminated prior to
completion of the aforementioned compulsory acquisition procedures, then Energy
Group ADSs will cease trading on the NYSE and the registration of Energy Group
ADSs under the Exchange Act would be terminated following completion of the
aforementioned compulsory acquisition procedures.
 
(C) MARGIN SECURITIES
 
     Energy Group ADSs are currently "margin securities" under the regulations
of the Board of Governors of the US Federal Reserve System, which status has the
effect, among other things, of allowing US brokers to extend credit on the
collateral of Energy Group ADSs for the purposes of buying, carrying and trading
in securities ("Purpose Loans"). Depending on factors such as the number of
holders of record of Energy Group ADSs and the number and market value of
publicly held Energy Group ADSs following the purchase of Energy Group
Securities pursuant to the Texas Utilities Offer, it is possible that Energy
Group ADSs would no longer be eligible for listing on the NYSE. As a result,
Energy Group ADSs might no longer constitute margin securities and, therefore,
could no longer be used as collateral for Purpose Loans made by US brokers.
 
11  LEGAL AND REGULATORY MATTERS
 
(A) GENERAL
 
     Except as set out herein and other than the requirement to comply with the
Panel's requirements in relation to the City Code and with US securities laws,
TU Acquisitions is not aware of (i) any licence or regulatory permit that
appears to be material to the business of the TEG Group taken as a whole, which
might be adversely affected by TU Acquisitions's acquisition of Energy Group
Securities as contemplated herein, or (ii) any approval or other action by any
domestic or foreign governmental, administrative or regulatory agency
 
                                     VIII-92
<PAGE>   401
 
or authority that appears to be material to the TEG Group taken as a whole, and
required for the acquisition or ownership of Energy Group Securities by TU
Acquisitions as contemplated herein. Should any such approval or other action be
required, TU Acquisitions currently contemplates that such approval or other
action would be sought. There can be no assurance that any such approval or
other action, if needed, would be obtained without substantial conditions being
attached thereto or that failure to obtain any such approval or other action
might not result in consequences adverse to The Energy Group's business.
 
(B) UNITED KINGDOM COMPETITION LAWS
 
     The Texas Utilities Offer gives rise to a merger situation qualifying for
investigation under section 75 of the Fair Trading Act 1973. It is therefore
conditional on an announcement being made in terms reasonably satisfactory to TU
Acquisitions that it is not the intention of the Secretary of State to refer the
Acquisition, or any matters arising from it, to the Monopolies and Mergers
Commission. In that connection TU Acquisitions has submitted a Merger Notice to
the Director General of Fair Trading and is in discussions with the DGES.
 
(C) UNITED KINGDOM ELECTRICITY REGULATION
 
     Eastern and its subsidiary companies hold licences issued under the
Electricity Act 1989. The Texas Utilities Offer is conditional on the DGES
indicating in terms reasonably satisfactory to TU Acquisitions that it is not
his intention to seek modifications to those licences and that he will not seek
undertakings or assurances from any member of the Texas Utilities Group or the
TEG Group except, in either case, on terms reasonably satisfactory to TU
Acquisitions. The Texas Utilities Offer is also conditional on the DGES
indicating in terms reasonably satisfactory to TU Acquisitions that, in
connection with the Acquisition, he will seek or agree to such modifications (if
any) and such other consents and/or directions (if any) as are in the reasonable
opinion of TU Acquisitions necessary or appropriate with respect to those
licences. However, TU Acquisitions will not invoke those Conditions in respect
of the DGES seeking, or indicating that it is his intention to seek,
modifications to any of the TEG Group's licences under the Electricity Act 1989
or undertakings or assurances from any member of the Texas Utilities Group or
the TEG Group provided that such modifications, undertakings or assurances
substantially reflect the assurances proposed by the DGES to PacifiCorp in
connection with the referral of the Original PacifiCorp Offer to the Monopolies
and Mergers Commission (as described in the Monopolies and Mergers Commission
Report relating to the Original PacifiCorp Offer published on 19 December 1997)
or are substantially in keeping with the proposals outlined by the DGES in his
consultation paper dated 24 February 1998 regarding modifications to public
electricity supply licences following takeovers.
 
(D) US ANTITRUST LAWS
 
     The Federal Trade Commission (the "FTC") and the Antitrust Division of the
Department of Justice (the "Antitrust Division") frequently scrutinise the
legality under the US antitrust laws of transactions such as the proposed
acquisition of the Peabody Coal Business by Lehman Merchant pursuant to the
Peabody Sale. At any time before or after the purchase of the Peabody Coal
Business, the FTC or the Antitrust Division could take such action under the US
antitrust laws as it deems necessary or desirable in the public interest,
including seeking to enjoin the purchase of the Peabody Coal Business pursuant
to the Peabody Sale, or seeking divestiture of the Peabody Coal Business.
Private parties may also bring legal action under the US antitrust laws in
certain circumstances. There can be no assurance that a challenge to the Peabody
Sale on US antitrust grounds will not be made or, if such a challenge is made,
of the result.
 
(E) US POWER MARKETING REGULATION
 
     Certain subsidiaries (the "Power Subsidiaries") of Citizens Power, an
indirect wholly-owned subsidiary of The Energy Group, are engaged in market-rate
based electric power marketing in the US or otherwise hold public utility assets
that are subject to the jurisdiction of the FERC. In a number of similar recent
situations, including the acquisition of Citizens Power by The Energy Group, the
FERC has asserted that a transfer of control of a licensed power marketer
requires FERC approval under section 203 of the US Federal Power Act.
Accordingly, the FERC could assert that any transfer of control of the Power
Subsidiaries resulting from
                                     VIII-93
<PAGE>   402
 
completion of the Peabody Sale requires FERC approval. Pursuant to the
provisions of the Peabody Sale Agreement (summarised in paragraph 6 of this
Appendix VIII ("Material Contracts")), Lehman Merchant will acquire Citizens
Power (including the Power Subsidiaries) with such sale conditional upon,
amongst other things, the completion of the Texas Utilities Offer and FERC
approval. Application for approval of the sale of the Power Subsidiaries to
Lehman Merchant has been made to the FERC, and the Texas Utilities Offer is
conditional upon the Peabody Sale Agreement becoming unconditional.
 
(F) AUSTRALIAN FOREIGN INVESTMENT REVIEW
 
     The acquisition by Lehman Merchant pursuant to the Peabody Sale Agreement
of ownership of Peabody Australia's coal operations is subject to the Foreign
Acquisitions and Takeovers Act 1975 of Australia. Under that Act, the Treasurer
of Australia has broad powers to prohibit or place conditions on the acquisition
of interests in Australian business operations by foreign investors if such
acquisitions are found to be contrary to the national interest. If a
notification of a proposed acquisition is made to the Australian Foreign
Investment Review Board, the Treasurer may approve the acquisition but is
precluded from taking any action with respect to the acquisition after the
expiration of a 40-day review period, although this period may be extended for
up to 90 days. The Foreign Investment Review Board was notified of the proposed
acquisition on 5 March 1998 and, absent unforeseen circumstances, would expect
to receive the Treasurer's approval within 40 days of that date.
 
(G) US STATE TAKEOVER LAWS
 
     A number of states of the US have adopted takeover laws and regulations
which purport, in varying degrees, to be applicable to attempts to acquire
securities of corporations which have substantial assets, shareholders,
principal executive offices or principal places of business in such states. TU
Acquisitions believes that no such US state takeover statutes apply to the Texas
Utilities Offer and TU Acquisitions has not attempted to comply with any such US
state takeover statutes in connection with the Texas Utilities Offer. TU
Acquisitions reserves the right to challenge the validity or applicability of
any US state law allegedly applicable to the Texas Utilities Offer and nothing
in this document nor any action taken in connection herewith is intended as a
waiver of that right. In the event that any US state takeover statute is
asserted to be applicable to the Texas Utilities Offer and an appropriate court
does not determine that such law or regulation is not applicable to the Texas
Utilities Offer, TU Acquisitions might be required to file certain information
with, or to receive approvals from, the relevant US state authorities and might
be unable to purchase Energy Group Securities pursuant to the Texas Utilities
Offer or be delayed in continuing or consummating the Texas Utilities Offer. In
such case TU Acquisitions may not be obliged to purchase such Energy Group
Securities.
 
(H) LAWS OF OTHER JURISDICTIONS
 
     The Energy Group and certain of its subsidiaries conduct business in
certain countries in addition to the United Kingdom and the US where regulatory
filings or approvals may be required in connection with the Texas Utilities
Offer. Certain of such filings or approvals, if required, may not be made or
obtained prior to the expiry of the Texas Utilities Offer. There is no assurance
that any such approvals would be obtained or that adverse consequences to Texas
Utilities's or The Energy Group's business might not result from a failure to
obtain such approvals or from conditions that might be imposed in connection
therewith.
 
12  UNITED KINGDOM TAXATION
 
     THE FOLLOWING PARAGRAPHS, WHICH ARE INTENDED AS A GENERAL GUIDE ONLY, ARE
BASED ON CURRENT UNITED KINGDOM LEGISLATION AND INLAND REVENUE PRACTICE. THEY
SUMMARISE CERTAIN LIMITED ASPECTS OF THE UNITED KINGDOM TAXATION TREATMENT OF
ACCEPTANCE OF THE TEXAS UTILITIES OFFER AND, WHERE APPLICABLE, ELECTION FOR THE
SHARE ALTERNATIVE AND/OR THE LOAN NOTE ALTERNATIVE, AND THEY RELATE ONLY TO THE
POSITION OF HOLDERS OF ENERGY GROUP SHARES WHO ARE THE BENEFICIAL OWNERS OF
THEIR ENERGY GROUP SHARES, WHO HOLD THEIR ENERGY GROUP SHARES AS AN INVESTMENT
(OTHERWISE THAN UNDER A PERSONAL EQUITY PLAN), AND (EXCEPT INSOFAR AS EXPRESS
REFERENCE IS MADE TO THE TREATMENT OF NON-UNITED KINGDOM RESIDENTS) WHO ARE
RESIDENT OR ORDINARILY RESIDENT IN THE UNITED KINGDOM FOR TAX PURPOSES.
SHAREHOLDERS WHO ARE IN ANY DOUBT AS TO THEIR TAXATION POSITION OR
                                     VIII-94
<PAGE>   403
 
WHO ARE SUBJECT TO TAXATION IN ANY JURISDICTION OTHER THAN THE UNITED KINGDOM,
SHOULD CONSULT AN APPROPRIATE PROFESSIONAL ADVISER.
 
(A) TAXATION OF CHARGEABLE GAINS
 
     Liability to United Kingdom taxation on chargeable gains ("CGT") will
depend on the particular circumstances of holders of Energy Group Shares and on
the form of consideration received.
 
     (I) CASH
 
     To the extent that a holder of Energy Group Shares receives cash under the
Texas Utilities Offer, this will constitute a disposal, or part disposal, of his
Energy Group Shares for CGT purposes. Such a disposal or part disposal may,
depending on that shareholder's individual circumstances, give rise to a
liability to CGT.
 
     (II) LOAN NOTES
 
     A holder of Energy Group Shares who, either alone or together with persons
connected with him, holds not more than 5 per cent. of the shares in, or of any
class of debentures of, The Energy Group, will not be treated as making a
disposal of his Energy Group Shares for CGT purposes to the extent that he
receives Loan Notes by way of consideration. In the case of a shareholder who is
an individual, the Loan Notes should not constitute "qualifying corporate bonds"
for CGT purposes. Accordingly, any gain or loss which would otherwise have
arisen on a disposal of his Energy Group Shares will be "rolled over" into the
Loan Notes, and the Loan Notes will be treated as the same asset as his Energy
Group Shares, acquired at the same time and price as his Energy Group Shares.
Indexation relief will continue to accrue during the period of ownership of the
Loan Notes. In the case of a shareholder within the charge to United Kingdom
corporation tax, the Loan Notes will constitute "qualifying corporate bonds" for
CGT purposes. Accordingly, any gain or loss which would otherwise have arisen on
a disposal of its Energy Group Shares for their market value at the date the
Texas Utilities Offer becomes unconditional, or, if later, the date on which the
relevant shareholder accepts the Texas Utilities Offer, will be calculated, and
will be "held over" until such shareholder subsequently disposes of the Loan
Notes. Indexation relief will not accrue on Loan Notes held by such a
shareholder.
 
     A holder of Energy Group Shares who, either alone or together with persons
connected with him, holds more than 5 per cent. of the shares in, or of any
class of debentures of, The Energy Group is advised that an application to the
Inland Revenue has been made for clearance under section 138 of the Taxation of
Chargeable Gains Act 1992. The Inland Revenue has not yet granted such
clearance. Subject to the granting of this clearance, any such holder of Energy
Group Shares will be treated in the manner described in the previous paragraph.
 
     A subsequent disposal of Loan Notes (including their redemption or
repayment) may give rise to a liability to CGT.
 
     (III) TEXAS UTILITIES COMMON STOCK
 
     To the extent that a holder of Energy Group Shares receives Texas Utilities
Common Stock under the Texas Utilities Offer, this will constitute a disposal,
or part disposal, of his Energy Group Shares for CGT purposes for a
consideration equal to the market value of the Texas Utilities Common Stock
received at the date the Texas Utilities Offer becomes unconditional, or, if
later, the date on which the relevant shareholder accepts the Texas Utilities
Offer. Such a disposal or part disposal may, depending on that shareholder's
individual circumstances, give rise to a liability to CGT.
 
     (IV) NON-UNITED KINGDOM RESIDENT HOLDERS OF ENERGY GROUP SHARES AND/OR
ENERGY GROUP ADSS
 
     Holders of Energy Group Shares and/or Energy Group ADSs who are not
resident or ordinarily resident for tax purposes in the United Kingdom may be
liable to CGT on capital gains realised on the disposal of their Energy Group
Shares or Energy Group ADSs if such shares or ADSs are used, held or acquired
for the purposes of a trade, profession or vocation carried on in the United
Kingdom through a branch or agency or for
 
                                     VIII-95
<PAGE>   404
 
the purposes of such branch or agency. Such holders may also be subject to
foreign taxation on any gain under local law.
 
(B) TAXATION OF LOAN NOTES
 
     (I) WITHHOLDING TAX
 
     Payment of interest on the Loan Notes will be made subject to the deduction
of United Kingdom income tax at the lower rate (currently, 20 per cent.) unless
TU Acquisitions has been directed by the Inland Revenue, in respect of a
particular holding of Loan Notes, to make the payment free from deduction or
subject to a reduced rate of deduction (by virtue of relief under the terms of
an applicable double taxation agreement). Such a direction will only be made
following an application in the appropriate manner to the relevant tax
authorities by the holder of the relevant Loan Notes.
 
     (II) INDIVIDUALS
 
     The gross amount of interest on the Loan Notes will form part of the
recipient's income for the purposes of United Kingdom income tax, credit being
allowed for the tax deducted. Individuals who are taxable only at the lower rate
or the basic rate (currently, 23 per cent.) will have no further tax to pay in
respect of the interest. Individuals whose income tax liability is less than the
aggregate of the tax deducted from other income paid to them and the tax
deducted in respect of interest on the Loan Notes will be entitled to an
appropriate repayment of tax. Individuals who are subject to tax at the higher
rate (currently, 40 per cent.) will have to account for additional tax to the
extent that tax at such rate on the gross amount of the interest exceeds the
credit for the tax deducted.
 
     Under the "accrued income scheme", a transfer of Loan Notes may also give
rise to a charge to United Kingdom income tax in respect of an amount
representing interest on the Loan Notes which has accrued since the preceding
interest payment date. Any amount charged to United Kingdom income tax in this
way will be deducted from the proceeds of disposal for CGT purposes.
 
     (III) CORPORATES
 
     Holders of Loan Notes within the charge to United Kingdom corporation tax
in respect of the Loan Notes will generally bring into account for the purposes
of corporation tax on income, interest and profits, gains and losses arising
from fluctuations in the value of, and disposals of, the Loan Notes in each
accounting period, broadly in accordance with the accounting treatment of such
holders authorised for this purpose. Credit against corporation tax will be
given for any income tax deducted from the payment of interest.
 
(C) TAXATION OF DIVIDEND INCOME
 
     A holder of Texas Utilities Common Stock (including any New Texas Utilities
Shares issued pursuant to the Share Alternative) will generally be liable to
income tax or corporation tax in the United Kingdom on the aggregate of any
dividend received from Texas Utilities and any tax deducted at source in the US
(see below under "United States federal income taxation") and any tax deducted
in the United Kingdom (see below) in relation to that dividend. In computing
that liability to taxation, credit will be given for any tax deducted in the US
and any tax deducted in the United Kingdom.
 
     Individuals will not be entitled to a repayment by the Inland Revenue of
the US tax deducted in respect of dividends on the Texas Utilities Common Stock.
Individuals whose income tax liability is less than the aggregate of the tax
deducted from other income paid to them, and the tax deducted in the US and any
tax deducted in the United Kingdom in respect of dividends on the Texas
Utilities Common Stock, may be entitled to a repayment of part or all of the
United Kingdom tax. Where United Kingdom income tax is deducted from such
dividends, individuals who are subject to income tax at the lower rate or the
basic rate will have no further United Kingdom tax to pay in respect of the
dividend. Where United Kingdom income tax is not deducted from such dividends,
individuals who are subject to income tax at the lower rate or the basic rate
will have to account for additional tax to the extent that tax at the lower rate
on the aggregate of the dividend
 
                                     VIII-96
<PAGE>   405
 
received and the tax deducted in the US exceeds the tax deducted in the US.
Individuals who are subject to income tax at the higher rate (currently, 40 per
cent.) will have to account for additional tax to the extent that tax at such
rate on the aggregate of the dividend received and the tax deducted in the US
and, where applicable, the United Kingdom in relation to the dividend exceeds
the tax deducted in the US and the United Kingdom.
 
     Corporate holders of Texas Utilities Common Stock will generally have to
account for additional tax to the extent that corporation tax at the rate at
which such holder pays tax (currently, 31 per cent. in the case of most
corporate holders) on the aggregate of the dividend received and the tax
deducted in the US and, where applicable, the United Kingdom in relation to the
dividend exceeds the tax deducted in the US and the United Kingdom. Although no
repayment from the Inland Revenue of any tax deducted in the US will be
available to a holder of Texas Utilities Common Stock, in the case of a
corporate holder of Texas Utilities Common Stock which controls 10 per cent. or
more of the voting stock of Texas Utilities, credit will also be available
against corporation tax on the dividend for US tax paid by Texas Utilities in
respect of the profits out of which the dividend is paid.
 
     No liability to income tax will arise for individual holders of Texas
Utilities Common Stock who, although United Kingdom resident, are not domiciled
in the United Kingdom, or for Commonwealth citizens or citizens of the Republic
of Ireland who are not ordinarily resident in the United Kingdom, except to the
extent that amounts are remitted to the United Kingdom (or are treated for tax
purposes as remitted to the United Kingdom).
 
     An agent in the United Kingdom who, on behalf of a holder of Texas
Utilities Common Stock, collects a dividend paid by Texas Utilities, may be
required to deduct and account to the United Kingdom Inland Revenue for United
Kingdom income tax (currently, at the rate of 20 per cent.). However, credit
will be given for tax deducted in the US, thereby reducing the aggregate
deduction to 20 per cent. of the gross dividend.
 
(D) GENERAL
 
     Special tax provisions may apply to holders of Energy Group Shares who have
acquired or acquire their Energy Group Shares by exercising options under the
Energy Group Share Schemes, including provisions imposing a charge to income
tax.
 
(E) STAMP DUTY AND STAMP DUTY RESERVE TAX ("SDRT")
 
     These comments are intended as a guide to the general position and do not
relate to persons such as intermediaries and persons connected with depositary
arrangements or clearance services, to whom special rules apply.
 
     (I) ACCEPTANCE OF THE TEXAS UTILITIES OFFER
 
     No stamp duty or SDRT will be payable by holders of Energy Group Shares as
a result of accepting the Texas Utilities Offer.
 
     (II) LOAN NOTES
 
     Under current Inland Revenue practice, no stamp duty or SDRT will be
payable on the issue of, or a transfer or sale of (or an agreement to transfer
or sell) Loan Notes.
 
     (III) TEXAS UTILITIES COMMON STOCK
 
     No stamp duty or SDRT will be payable on the issue of Texas Utilities
Common Stock. No SDRT will be payable on a transfer or sale of (or an agreement
to transfer or sell) Texas Utilities Common Stock. Stamp duty may, in certain
circumstances, be payable on a transfer or sale of Texas Utilities Common Stock,
including where the transfer is executed in the United Kingdom; this will be
payable by the transferee or the purchaser.
 
                                     VIII-97
<PAGE>   406
 
13  UNITED STATES FEDERAL INCOME TAXATION
 
     The following paragraphs address certain United States federal income tax
consequences applicable to holders of Energy Group Securities who accept the
Texas Utilities Offer and, except as otherwise noted, are United States Holders
(as defined below). This summary is based on the Internal Revenue Code, and
administrative pronouncements, judicial decisions and existing and proposed
Treasury Regulations thereunder, changes to any of which (which may be
retroactive) may affect the tax consequences described herein. This summary
assumes that the Energy Group Securities have been held as capital assets. It
does not address the tax treatment of individuals who have received Energy Group
Securities in connection with employment, such as by the exercise of options
granted to employees. This summary also assumes that The Energy Group is not and
has never been either a passive foreign investment company or a controlled
foreign corporation for US federal income tax purposes. This summary does not
discuss all tax consequences that may be relevant to a holder of Energy Group
Securities in the light of such holder's particular circumstances or to holders
subject to special rules, such as certain financial institutions, regulated
investment companies, insurance companies, dealers in securities, exempt
organisations, persons holding Energy Group Securities as part of a hedge,
straddle or conversion transaction and holders that are residents of countries
other than the United States or whose functional currency is not the United
States dollar.
 
(A) UNITED STATES HOLDERS
 
     As used herein, a "United States Holder" means a beneficial owner of Energy
Group Securities that is a citizen or resident of the United States, a
corporation, partnership or other entity created or organized in or under the
laws of the United States or any political subdivision thereof, an estate the
income of which is subject to United States federal income taxation regardless
of its source, or a trust the administration of which is subject to the primary
supervision of a court within the United States and for which one or more US
Persons have the authority to control all substantial decisions. An individual
may, subject to certain exceptions, be deemed to be a resident of the United
States (as opposed to a non-resident alien) by virtue of being present in the
United States on at least 31 days in the calendar year and for an aggregate of
at least 183 days during a three-year period ending in the current calendar year
(counting for such purposes all of the days present in the current year,
one-third of the days present in the immediately preceding year, and one-sixth
of the days present in the second preceding year). A "Non-United States Holder"
is a holder that is not a United States Holder.
 
  (I) ACCEPTANCE OF TEXAS UTILITIES OFFER
 
     In general, a United States Holder of Energy Group Securities that sells
such securities pursuant to the Texas Utilities Offer will, for United States
federal income tax purposes, recognise gain or loss equal to the difference
between such holder's adjusted tax basis in the Energy Group Securities
transferred and the amount realized in exchange therefor. The amount realized
will equal the sum of (i) the dollar value of the pounds sterling received, and
(ii) the fair market value of any Texas Utilities Common Stock received. Such
gain or loss generally will be capital gain or loss. Under the US Taxpayer
Relief Act of 1997, an individual taxpayer who has held a capital asset for more
than 18 months generally will be taxed on gain from the sale of that asset at a
maximum rate of 20 per cent. A 28 per cent. maximum rate generally applies to
the sale of a capital asset held more than one year but not more than 18 months.
 
     In addition, an accrual basis United States Holder of Energy Group
Securities that sells such securities pursuant to the Texas Utilities Offer and
does not elect to be treated as a cash basis taxpayer pursuant to the foreign
currency exchange regulations may have a foreign currency exchange gain or loss
for United States federal income tax purposes because of differences between the
US dollars/pounds sterling exchange rates prevailing on the date of sale and on
the date of payment. Any such currency gain or loss would be treated as ordinary
income or loss and would be in addition to gain or loss realised by the holder
on the disposition of Energy Group Securities pursuant to the Texas Utilities
Offer. Regardless of his method of accounting, a United States Holder will
recognise ordinary income or loss upon the subsequent sale or exchange of any
pounds sterling received as a result of the acceptance of the Texas Utilities
Offer. Such income or loss will equal the difference between the amount realised
from the sale or exchange and such holder's tax basis in the
                                     VIII-98
<PAGE>   407
 
pounds sterling received, which generally will equal the US dollar value of the
pounds sterling on the date of payment.
 
  (II) DISTRIBUTIONS
 
     Distributions, if any, made with respect to Texas Utilities Common Stock
will be treated as ordinary dividend income to the extent of Texas Utilities's
current or accumulated earnings and profits, then as a return of capital to the
extent of tax basis, and then as gain from the sale of stock. In the case of
corporate holders, such distributions, to the extent that they are treated as
ordinary dividend income, will generally qualify for the dividends received
deduction (subject to generally applicable exceptions).
 
  (III) DISPOSAL OF TEXAS UTILITIES COMMON STOCK
 
     Upon the sale or exchange of Texas Utilities Common Stock, United States
Holders will recognise capital gain or loss equal to the difference between the
amount realized from the sale or exchange and such holder's tax basis in the
shares. A United States Holder's tax basis in the Texas Utilities Common Stock
generally will equal its fair market value at the time gain or loss is
recognized upon acceptance of the Texas Utilities Offer.
 
  (IV) INFORMATION REPORTING AND BACKUP WITHHOLDING
 
     In general, information reporting will apply with respect to the cash
proceeds of the Texas Utilities Offer to certain non-corporate United States
Holders of Energy Group Securities.
 
     A United States Holder of Energy Group Securities may be subject to a 31
per cent. US back-up withholding tax with respect to the cash payment if (i) the
holder fails to furnish a taxpayer identification number ("TIN") to the payor or
establish an exemption from back-up withholding, (ii) the US Internal Revenue
Service ("IRS") notifies the payor that the TIN furnished by the holder is
incorrect, (iii) there has been a notified payee underreporting with respect to
interest or dividends described in section 3406(c) of the Internal Revenue Code,
or (iv) there is a failure of the holder to certify under the penalty of perjury
that the holder is not subject to withholding as described in section 3406 of
the Internal Revenue Code.
 
     To prevent back-up withholding on any cash payment delivered pursuant to
the Texas Utilities Offer, each United States Holder of Energy Group ADSs that
accepts the Texas Utilities Offer by means of the Letter of Transmittal and each
United States Holder of Energy Group Shares that accepts the Texas Utilities
Offer by sending the Form of Acceptance to the US Depositary must provide the US
Depositary with that holder's correct taxpayer identification number and certify
that the holder is not subject to US back-up federal income tax withholding by
completing the Substitute Form W-9 included in the Letter of Transmittal or Form
of Acceptance.
 
(B) NON-UNITED STATES HOLDERS
 
  (I) DISTRIBUTIONS
 
     Distributions, if any, made with respect to Texas Utilities Common Stock
and paid to a Non-United States Holder generally will be subject to withholding
of United States federal income tax at the rate of 30 per cent. of the amount of
the dividend, or such lower rate as may be specified by an applicable double
taxation treaty. Under the provisions of the US/United Kingdom double taxation
treaty, the rate of U.S. federal withholding tax on a dividend paid by Texas
Utilities to a person resident in the United Kingdom for tax purposes who is
beneficially entitled to the dividend and who does not control 10 per cent. or
more of the voting stock of Texas Utilities is, subject to certain exceptions,
reduced to 15 per cent. of the amount of the dividend. However, dividends that
are effectively connected with the conduct of a trade or business by the
Non-United States Holder within the United States, or, if a double taxation
treaty applies (such as the US/United Kingdom double taxation treaty), are
attributable to a United States permanent establishment of the Non-United States
Holder, are not subject to the 30 per cent. withholding tax but instead are
subject to United States federal income tax on a net income basis at applicable
graduated individual or corporate rates.
 
                                     VIII-99
<PAGE>   408
 
Any such effectively connected dividends received by a corporate Non-United
States Holder may, under certain circumstances, be subject to an additional
"branch profits tax" at a 30 per cent. rate or such lower rate as may be
specified by an applicable double taxation treaty.
 
     In the case of dividends paid prior to 1 January 1999, the payor is
responsible for determining whether a reduced rate of withholding is
appropriate. Where Texas Utilities is satisfied that the Non-United States
Holder beneficially entitled to a dividend is resident in the United Kingdom for
purposes of the US/United Kingdom double taxation treaty, Texas Utilities will
withhold US tax at the treaty rate of 15 per cent. of the amount of the
dividend. In the case of dividends paid after 31 December 1998, a Non-United
States Holder who wishes to claim the benefit of an applicable treaty rate must
satisfy certain certification and other requirements. A Non-United States Holder
must comply with certain certification and disclosure requirements in order to
be exempt from withholding under the effectively connected income exemption
discussed above.
 
     If it is subsequently determined that some or all of a distribution on the
Texas Utilities Common Stock should be treated as a return of capital, a
Non-United States Holder may obtain a refund of some or all of the tax withheld
by filing an appropriate claim for refund with the IRS. A Non-United States
Holder eligible for a reduced rate of withholding pursuant to an income tax
treaty may obtain a refund of any excess amounts withheld by filing an
appropriate claim for refund with the IRS.
 
  (II) DISPOSAL OF TEXAS UTILITIES COMMON STOCK
 
     A Non-United States Holder will generally not be subject to United States
federal income tax with respect to gain recognized on a sale, exchange,
redemption or other disposition of the Texas Utilities Common Stock unless (i)
the gain is effectively connected with a trade or business of the Non-United
States Holder in the United States, or, if a double tax treaty applies (such as
the US/United Kingdom treaty), is attributable to a United States permanent
establishment of the Non-United States Holder, (ii) in the case of a Non-United
States Holder who is an individual and holds the Texas Utilities Common Stock as
a capital asset, such holder is present in the United States for 183 days or
more in the taxable year of the sale or other disposition and certain other
conditions are met, (iii) the Non-United States Holder is subject to tax
pursuant to certain provisions of the Internal Revenue Code applicable to United
States expatriates, or (iv) the Non-United States Holder holds more than 5 per
cent. of the Texas Utilities Common Stock during a certain prescribed period.
 
  (III) INFORMATION REPORTING AND BACKUP WITHHOLDING
 
     No information reporting or backup withholding will be required with
respect to any cash payment made pursuant to the Texas Utilities Offer if the
Non-United States Holder completes and sends to the US Depositary a Form W-8,
Certificate of Foreign Status, a copy of which is available, upon request, from
the US Depositary or the IRS.
 
     Information reporting and backup withholding generally will not apply under
current law to dividends paid to a Non-United States Holder of Texas Utilities
Common Stock at an address outside the United States that are subject to the 30
per cent. withholding discussed above (or that are not so subject because (i) a
tax treaty applies that reduces or eliminates such 30 per cent. withholding, or
(ii) such withholding is not required under the effectively connected income
exception discussed above), provided that the payor does not have definite
knowledge that the payee is a United States person. However, in the case of
dividends paid after 31 December 1998, a Non-United States Holder generally
would be subject to information reporting (but not backup withholding) unless
certain certification procedures are complied with, either directly or through
an intermediary.
 
     THE FOREGOING DISCUSSION IS FOR GENERAL INFORMATION ONLY AND IS INTENDED TO
BE ONLY A SUMMARY OF THE PRINCIPAL UNITED STATES FEDERAL INCOME TAX
CONSIDERATIONS OF THE TEXAS UTILITIES OFFER. EACH HOLDER OF ENERGY GROUP
SECURITIES SHOULD CONSULT HIS OR HER OWN TAX ADVISER CONCERNING THE UNITED
STATES FEDERAL AND APPLICABLE STATE, LOCAL, FOREIGN AND OTHER TAX CONSEQUENCES
OF THE TEXAS UTILITIES OFFER.

                                  APPENDIX IX
 
                  CERTAIN PROVISIONS OF THE COMPANIES ACT 1985
 
428. TAKEOVER OFFERS
 
     (1) In this Part of this Act "takeover offer" means an offer to acquire all
the shares, or all the shares of any class or classes, in a company (other than
shares which at the date of the offer are already held by the offeror), being an
offer on terms which are the same in relation to all the shares to which the
offer relates or, where those shares include shares of different classes, in
relation to all the shares of each class.
 
     (2) In subsection (1) "shares" means shares which have been allotted on the
date of the offer but a takeover offer may include among the shares to which it
relates all or any shares that are subsequently allotted before a date specified
in or determined in accordance with the terms of the offer.
 
     (3) The terms offered in relation to any shares shall for the purposes of
this section be treated as being the same in relation to all the shares or, as
the case may be, all the shares of a class to which the offer relates
notwithstanding any variation permitted by subsection (4).
 
     (4) A variation is permitted by this subsection where --
 
          (a) the law of a country or territory outside the United Kingdom
     precludes an offer of consideration in the form or any of the forms
     specified in the terms in question or precludes it except after compliance
     by the offeror with conditions with which he is unable to comply or which
     he regards as unduly onerous; and
 
          (b) the variation is such that the persons to whom an offer of
     consideration in that form is precluded are able to receive consideration
     otherwise than in that form but of substantially equivalent value.
 
     (5) The reference in subsection (1) to shares already held by the offeror
includes a reference to shares which he has contracted to acquire but that shall
not be construed as including shares which are the subject of a contract binding
the holder to accept the offer when it is made, being a contract entered into by
the holder either for no consideration and under seal or for no consideration
other than a promise by the offeror to make the offer.
 
     (6) In the application of subsection (5) to Scotland the words "and under
seal" shall be omitted.
 
     (7) Where the terms of an offer make provision for their revision and for
acceptances on the previous terms to be treated as acceptances on the revised
terms, the revision shall not be regarded for the purposes of this Part of this
Act as the making of a fresh offer and references in this Part of this Act to
the date of the offer shall accordingly be construed as references to the date
on which the original offer was made.
 
     (8) In this Part of this Act "the offeror" means, subject to section 430D,
the person making a takeover offer and "the company" means the company whose
shares are the subject of the offer.
 
429. RIGHT OF OFFEROR TO BUY OUT MINORITY SHAREHOLDERS
 
     (1) If, in a case in which a takeover offer does not relate to shares of
different classes, the offeror has by virtue of acceptances of the offer
acquired or contracted to acquire not less than nine-tenths in value of the
shares to which the offer relates he may give notice to the holder of any shares
to which the offer relates which the offeror has not acquired or contracted to
acquire that he desires to acquire those shares.
 
     (2) If, in a case in which a takeover offer relates to shares of different
classes, the offeror has by virtue of acceptances of the offer acquired or
contracted to acquire not less than nine-tenths in value of the shares of any
class to which the offer relates, he may give notice to the holder of any shares
of that class which the offeror has not acquired or contracted to acquire that
he desires to acquire those shares.
 
     (3) No notice shall be given under subsection (1) or (2) unless the offeror
has acquired or contracted to acquire the shares necessary to satisfy the
minimum specified in that subsection before the end of the period of
 
                                      IX-1
<PAGE>   413
 
four months beginning with the date of the offer; and no such notice shall be
given after the end of the period of two months beginning with the date on which
he has acquired or contracted to acquire shares which satisfy that minimum.
 
     (4) Any notice under this section shall be given in the prescribed manner;
and when the offeror gives the first notice in relation to an offer he shall
send a copy of it to the company together with a statutory declaration by him in
the prescribed form stating that the conditions for the giving of the notice are
satisfied.
 
     (5) Where the offeror is a company (whether or not a company within the
meaning of this Act) the statutory declaration shall be signed by a director.
 
     (6) Any person who fails to send a copy of a notice or a statutory
declaration as required by subsection (4) or makes such a declaration for the
purposes of that subsection knowing it to be false or without having reasonable
grounds for believing it to be true shall be liable to imprisonment or a fine,
or both, and for continued failure to send the copy or declaration, to a daily
default fine.
 
     (7) If any person is charged with an offence for failing to send a copy of
a notice as required by subsection (4) it is a defence for him to prove that he
took reasonable steps for securing compliance with that subsection.
 
     (8) When during the period within which a takeover offer can be accepted
the offeror acquires or contracts to acquire any of the shares to which the
offer relates but otherwise than by virtue of acceptances of the offer, then,
if --
 
          (a) the value of the consideration for which they are acquired or
     contracted to be acquired ("the acquisition consideration") does not at
     that time exceed the value of the consideration specified in the terms of
     the offer; or
 
          (b) those terms are subsequently revised so that when the revision is
     announced the value of the acquisition consideration, at the time mentioned
     in paragraph (a) above, no longer exceeds the value of the consideration
     specified in those terms,
 
the offeror shall be treated for the purposes of this section as having acquired
or contracted to acquire those shares by virtue of acceptances of the offer; but
in any other case those shares shall be treated as excluded from those to which
the offer relates.
 
430. EFFECT OF NOTICE UNDER S.429
 
     (1) The following provisions shall, subject to section 430C, have effect
where a notice is given in respect of any shares under section 429.
 
     (2) The offeror shall be entitled and bound to acquire those shares on the
terms of the offer.
 
     (3) Where the terms of an offer are such as to give the holder of any
shares a choice of consideration the notice shall give particulars of the choice
and state --
 
          (a) that the holder of the shares may within six weeks from the date
     of the notice indicate his choice by a written communication sent to the
     offeror at an address specified in the notice; and
 
          (b) which consideration specified in the offer is to be taken as
     applying in default of his indicating a choice as aforesaid;
 
and the terms of the offer mentioned in subsection (2) shall be determined
accordingly.
 
                                      IX-2
<PAGE>   414
 
     (4) Subsection (3) applies whether or not any time-limit or other
conditions applicable to the choice under the terms of the offer can still be
complied with; and if the consideration chosen by the holder of the shares --
 
          (a) is not cash and the offeror is no longer able to provide it; or
 
          (b) was to have been provided by a third party who is no longer bound
     or able to provide it,
 
the consideration shall be taken to consist of an amount of cash payable by the
offeror which at the date of the notice is equivalent to the chosen
consideration.
 
     (5) At the end of six weeks from the date of the notice the offerer shall
forthwith --
 
          (a) send a copy of the notice to the company; and
 
          (b) pay or transfer to the company the consideration for the shares to
     which the notice relates.
 
     (6) If the shares to which the notice relates are registered the copy of
the notice sent to the company under subsection (5)(a) shall be accompanied by
an instrument of transfer executed on behalf of the shareholder by a person
appointed by the offeror; and on receipt of that instrument the company shall
register the offeror as the holder of those shares.
 
     (7) If the shares to which the notice relates are transferable by the
delivery of warrants or other instruments the copy of the notice sent to the
company under subsection (5)(a) shall be accompanied by a statement to that
effect; and the company shall on receipt of the statement issue the offeror with
warrants or other instruments in respect of the shares and those already in
issue in respect of the shares shall become void.
 
     (8) Where the consideration referred to in paragraph (b) of subsection (5)
consists of shares or securities to be allotted by the offeror the reference in
that paragraph to the transfer of the consideration shall be construed as a
reference to the allotment of the shares or securities to the company.
 
     (9) Any sum received by a company under paragraph (b) of subsection (5) and
any other consideration received under that paragraph shall be held by the
company on trust for the person entitled to the shares in respect of which the
sum or other consideration was received.
 
     (10) Any sum received by a company under paragraph (b) of subsection (5),
and any dividend or other sum accruing from any other consideration received by
a company under that paragraph, shall be paid into a separate bank account,
being an account the balance on which bears interest at an appropriate rate and
can be withdrawn by such notice (if any) as is appropriate.
 
     (11) Where after reasonable enquiry made at such intervals as are
reasonable the person entitled to any consideration held on trust by virtue of
subsection (9) cannot be found and twelve years have elapsed since the
consideration was received or the company is wound up the consideration
(together with any interest, dividend or other benefit that has accrued from it)
shall be paid into court.
 
     (12) In relation to a company registered in Scotland, subsections (13) and
(14) shall apply in place of subsection (11).
 
     (13) Where after reasonable enquiry made at such intervals as are
reasonable the person entitled to any consideration held on trust by virtue of
subsection (9) cannot be found and twelve years have elapsed since the
consideration was received or the company is wound up --
 
          (a) the trust shall terminate;
 
          (b) the company or, as the case may be, the liquidator shall sell any
     consideration other than cash and any benefit other than cash that has
     accrued from the consideration; and
 
          (c) a sum representing --
 
             (i) the consideration so far as it is cash;
 
             (ii) the proceeds of any sale under paragraph (b) above; and
 
             (iii) any interest, dividend or other benefit that has accrued from
        the consideration,
 
                                      IX-3
<PAGE>   415
 
shall be deposited in the name of the Accountant of Court in a bank account such
as is referred to in subsection (10) and the receipt for the deposit shall be
transmitted to the Accountant of Court.
 
     (14) Section 58 of the Bankruptcy (Scotland) Act 1985 (so far as consistent
with this Act) shall apply with any necessary modifications to sums deposited
under subsection (13) as that section applies to sums deposited under section
57(l)(a) of that Act.
 
     (15) The expenses of any such enquiry as is mentioned in subsection (11) or
(13) may be defrayed out of the money or other property held on trust for the
person or persons to whom the enquiry relates.
 
430A. RIGHT OF MINORITY SHAREHOLDER TO BE BOUGHT OUT BY OFFEROR
 
     (1) If a takeover offer relates to all the shares in a company and at any
time before the end of the period within which the offer can be accepted --
 
          (a) the offeror has by virtue of acceptances of the offer acquired or
     contracted to acquire some (but not all) of the shares to which the offer
     relates; and
 
          (b) those shares, with or without any other shares in the company
     which he has acquired or contracted to acquire, amount to not less than
     nine-tenths in value of all the shares in the company,
 
the holder of any shares to which the offer relates who has not accepted the
offer may by a written communication addressed to the offeror require him to
acquire those shares.
 
     (2) If a takeover offer relates to shares of any class or classes and at
any time before the end of the period within which the offer can be accepted --
 
          (a) the offeror has by virtue of acceptances of the offer acquired or
     contracted to acquire some (but not all) of the shares of any class to
     which the offer relates; and
 
          (b) those shares, with or without any other shares of that class which
     he has acquired or contracted to acquire, amount to not less than
     nine-tenths in value of all the shares of that class,
 
the holder of any shares of that class who has not accepted the offer may by a
written communication addressed to the offeror require him to acquire those
shares.
 
     (3) Within one month of the time specified in subsection (1) or, as the
case may be, subsection (2) the offeror shall give any shareholder who has not
accepted the offer notice in the prescribed manner of the rights that are
exercisable by him under that subsection; and if the notice is given before the
end of the period mentioned in that subsection it shall state that the offer is
still open for acceptance.
 
     (4) A notice under subsection (3) may specify a period for the exercise of
the rights conferred by this section and in that event the rights shall not be
exercisable after the end of that period; but no such period shall end less than
three months after the end of the period within which the offer can be accepted.
 
     (5) Subsection (3) does not apply if the offeror has given the shareholder
a notice in respect of the shares in question under section 429.
 
     (6) If the offeror fails to comply with subsection (3) he and, if the
offeror is a company, every officer of the company who is in default or to whose
neglect the failure is attributable, shall be liable to a fine and for continued
contravention, to a daily default fine.
 
     (7) If an offeror other than a company is charged with an offence for
failing to comply with subsection (3) it is a defence for him to prove that he
took all reasonable steps for securing compliance with that subsection.
 
430B. EFFECT OF REQUIREMENT UNDER S.430A
 
     (1) The following provisions shall, subject to section 430C, have effect

<PAGE>   416
 
     (2) The offeror shall be entitled and bound to acquire those shares on the
terms of the offer or on such other terms as may be agreed.
 
     (3) Where the terms of an offer are such as to give the holder of shares a
choice of consideration the holder of the shares may indicate his choice when
requiring the offeror to acquire them and the notice given to the holder under
section 430A(3) --
 
          (a) shall give particulars of the choice and of the rights conferred
     by this subsection; and
 
          (b) may state which consideration specified in the offer is to be
     taken as applying in default of his indicating a choice;
 
and the terms of the offer mentioned in subsection (2) shall be determined
accordingly.
 
     (4) Subsection (3) applies whether or not any time-limit or other
conditions applicable to the choice under the terms of the offer can still be
complied with; and if the consideration chosen by the holder of the shares --

the court may, on an application made by him within six weeks from the date on
which the notice was given --
 
          (a) order that the offeror shall not be entitled and bound to acquire
     the shares; or
 
          (b) specify terms of acquisition different from those of the offer.
 
     (2) If an application to the court under subsection (1) is pending at the
end of the period mentioned in subsection (5) of section 430 that subsection
shall not have effect until the application has been disposed of.
 
     (3) Where the holder of any shares exercises his rights under section 430A
the court may, on an application made by him or the offeror, order that the
terms on which the offeror is entitled and bound to acquire the shares shall be
such as the court thinks fit.
 
     (4) No order for costs or expenses shall be made against a shareholder
making an application under subsection (1) or (3) unless the court considers --
 
          (a) that the application was unnecessary, improper or vexatious; or
 
          (b) that there has been unreasonable delay in making the application
     or unreasonable conduct on his part in conducting the proceedings on the
     application.
 
     (5) Where a takeover offer has not been accepted to the extent necessary
for entitling the offeror to give notices under subsection (1) or (2) of section
429 the court may, on the application of the offeror, make an order authorising
him to give notices under that subsection if satisfied --
 
          (a) that the offeror has after reasonable enquiry been unable to trace
     one or more of the persons holding shares to which the offer relates;
 
          (b) that the shares which the offeror has acquired or contracted to
     acquire by virtue of acceptances of the offer, together with the shares
     held by the person or persons mentioned in paragraph (a), amount to not
     less than the minimum specified in that subsection; and
 
          (c) that the consideration offered is fair and reasonable;
                                      IX-5
<PAGE>   417
 
but the court shall not make an order under this subsection unless it considers
that it is just and equitable to do so having regard, in particular, to the
number of shareholders who have been traced but who have not accepted the offer.

offeror under those sections and sections 430 and 430B shall be respectively
joint rights and joint and several obligations of the joint offerors.
 
     (3) It shall be a sufficient compliance with any provision of those
sections requiring or authorising a notice or other document to be given or sent
by or to the joint offerors that it is given or sent by or to any of them; but
the statutory declaration required by section 429(4) shall be made by all of

longer able to provide the relevant consideration shall be construed as
references to none of the joint offerors being able to do so.
 
     (7) In section 430C references to the offeror shall be construed as
references to the joint offerors except that any application under subsection
(3) or (5) may be made by any of them and the reference in subsection (5)(a) to
the offeror having been unable to trace one or more of the persons holding
shares shall be construed as a reference to none of the offerors having been

430E. ASSOCIATES
 
     (1) The requirement in section 428(1) that a takeover offer must extend to

which associates of the offeror hold or have contracted to acquire; but, subject
to subsection (2), shares which any such associate holds or has contracted to
acquire, whether at the time when the offer is made or subsequently, shall be
disregarded for the purposes of any reference in this Part of this Act to the
shares to which a takeover offer relates.
 
     (2) Where during the period within which a takeover offer can be accepted
any associate of the offeror acquires or contracts to acquire any of the shares
to which the offer relates, then, if the condition specified in subsection

treated for the purposes of that section as shares to which the offer relates.
 
     (3) In section 430A(1)(b) and (2)(b) the reference to shares which the

          (a) a nominee of the offeror;

     or a nominee of such a holding company, subsidiary or fellow subsidiary;
 
          (c) a body corporate in which the offeror is substantially interested;
     or
                                      IX-6
<PAGE>   418
 
          (d) any person who is, or is a nominee of, a party to an agreement
     with the offeror for the acquisition of, or of an interest in, the shares
     which are the subject of the takeover offer, being an agreement which
     includes provisions imposing obligations or restrictions such as are
     mentioned in section 204(2)(a).
 
     (5) For the purposes of subsection (4)(b) a company is a fellow subsidiary
of another body corporate if both are subsidiaries of the same body corporate
but neither is a subsidiary of the other.
 
     (6) For the purposes of subsection (4)(c) an offeror has a substantial
interest in a body corporate if --
 
          (a) that body or its directors are accustomed to act in accordance
     with his directions or instructions; or
 
          (b) he is entitled to exercise or control the exercise of one-third or
     more of the voting power at general meetings of that body.
 
     (7) Subsections (5) and (6) of section 204 shall apply to subsection (4)(d)

430F. CONVERTIBLE SECURITIES
 
     (1) For the purposes of this Part of this Act securities of a company shall
be treated as shares in the company if they are convertible into or entitle the
holder to subscribe for such shares; and references to the holder of shares or a
shareholder shall be construed accordingly.
 
     (2) Subsection (1) shall not be construed as requiring any securities to be
treated --
 
          (a) as shares of the same class as those into which they are
     convertible or for which the holder is entitled to subscribe; or
 
          (b) as shares of the same class as other securities by reason only
     that the shares into which they are convertible or for which the holder is
     entitled to subscribe are of the same class.
