                          and, together with TU, the "Borrowers"); the lenders
                          listed in Schedule 2.01 (together with their
                          successors and assigns, the "Lenders"); CHEMICAL

                          the "CAF Agent"); and TEXAS COMMERCE BANK NATIONAL
                          ASSOCIATION, a national banking association ("TCB"),

                 The Lenders have been requested to extend credit to the
Borrowers to enable them, upon the terms and subject to the conditions set
forth herein (a) in the case of TU, to borrow term loans on the Effective Date,
in an aggregate principal amount not in excess of $300,000,000, and (b) in the
case of either Borrower, to borrow on a standby revolving credit basis on and
after the Effective Date and at any time prior to the Maturity Date (as
hereinafter defined), an aggregate principal amount not in excess of

subject to the conditions herein set forth.

effect) to reflect such changed rating system or the nonavailability of Ratings
from such Rating Agency, and pending agreement on such amendment (but subject
to clause (iv) above), the Rating in effect immediately prior to such change or
cessation will be used in determining the Facility Fee Percentage.  If any
Rating Agency shall not have a Rating in effect by reason of any action or
nonaction by TU Electric following or in anticipation of a ratings downgrade,
then such Rating Agency shall be deemed to have established a Rating in

For purposes of the foregoing, (i) if both D&P and Fitch have established

for TU Electric; (ii) if more than two

Ratings exist and the applicable Ratings established or deemed to have been
established by the Rating Agencies shall fall within different Categories, the
TU Applicable Margin shall be based upon the Category in which the largest
number of Ratings falls or is deemed to fall, provided, that if there shall be
no such Category, the middle Category shall apply; (iii) if only two Ratings

upon the lower of such Ratings; (iv) if neither S&P nor Moody's shall have a

ratings downgrade), the parties hereto shall negotiate in good faith to amend
the references to specific ratings in this definition (including by way of
substituting another Rating Agency mutually acceptable to the Borrowers and the
Agents for the Rating Agency with respect to which the rating system has
changed or for which no Rating is then in effect) to reflect such changed
rating system or the nonavailability of Ratings from such Rating Agency, and
pending agreement on such amendment (but subject to clause (iv) above), the
Rating in effect immediately prior to such change or cessation will be used in
determining the TU Applicable Margin.  If any Rating Agency shall not have a
Rating in effect by reason of any action or nonaction by TU Electric following
or in anticipation of a ratings downgrade, then such Rating Agency shall be
deemed to have established a Rating in Category 5.

For purposes of the foregoing, (i) if both D&P and Fitch have established
Ratings, only one of such Ratings shall be employed for purposes of determining
the TU Electric Applicable Margin and the Rating employed shall be the Rating
from the institution that has for the longest period of time had a Rating
established for TU Electric; (ii) if more than two Ratings exist and the
applicable Ratings established or deemed to have been established by the Rating
Agencies shall fall within different Categories, the TU Electric Applicable
Margin shall be based upon the Category in which the largest number of Ratings
falls or is deemed to fall, provided, that if there shall be no such Category,
the middle Category shall apply; (iii) if only two Ratings exist, the TU
Electric Applicable Margin shall, subject to clause (iv) below, be based upon
the lower of such Ratings; (iv) if neither S&P nor
   27
                                                                              23


Moody's shall have a Rating in effect, then the TU Electric Applicable Margin
shall be based upon Category 5; and (v) if any Rating established or deemed to
have been established by any Rating Agency shall be changed (other than as a
result of a change in the rating system of such Rating Agency), such change
shall be effective as of the date on which such change is first announced by
the Rating Agency making such change.  Each change in the TU Electric
Applicable Margin shall apply to all Eurodollar Standby Loans or Eurodollar
Term Loans that are outstanding at any time during the period commencing on the
effective date of such change and ending on the date immediately preceding the
effective date of the next such change.  If the rating system of any Rating
Agency shall change, or if any Rating Agency shall cease rating the first
mortgage bonds of TU Electric (other than by reason of any action or nonaction
by TU Electric following or in anticipation of a ratings downgrade), the
parties hereto shall negotiate in good faith to amend the references to
specific ratings in this definition (including by way of substituting another
Rating Agency mutually acceptable to the Borrowers and the Agents for the
Rating Agency with respect to which the rating system has changed or for which
no Rating is then in effect) to reflect such changed rating system or the
nonavailability of Ratings from such Rating Agency, and pending agreement on
such amendment (but subject to clause (iv) above), the Rating in effect
immediately prior to such change or cessation will be used in determining the
TU Electric Applicable Margin.  If any Rating Agency shall not have a Rating in
effect by reason of any action or nonaction by TU Electric following or in
anticipation of a ratings downgrade, then such Rating Agency shall be deemed to
have established a Rating in Category 5.

                 "TU Electric Mortgage" shall mean the Mortgage and Deed of
Trust dated as of December 1, 1983, from TU Electric to Irving Trust Company
(now The Bank of New York), Trustee, as amended or supplemented from time to
time.

                 "Type", when used in respect of any Loan or Borrowing, shall
refer to the Rate by reference to which interest on such Loan or on the Loans
comprising such Borrowing is determined. For purposes hereof, "Rate" shall
include the LIBO Rate, the Alternate Base Rate and the Fixed Rate.

                 "Voting Shares" shall mean, as to shares of a particular
corporation, outstanding shares of stock of any class of such corporation
entitled to vote in the election of
   28
                                                                              24


directors, excluding shares entitled so to vote only upon the happening of some
contingency.

                 "Wholly-Owned Subsidiary" shall mean any Consolidated
Subsidiary all the shares of common stock and other voting capital stock or
other voting ownership interests having ordinary voting power to vote in the
election of the board of directors or other governing body performing similar
functions (except directors' qualifying shares) of which are at the time
directly or indirectly owned by TU.

                 "Withdrawal Liability" shall mean liability of a Borrower
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 1.02.  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 expressly provided herein, all terms of an
accounting or financial nature shall be construed in accordance with GAAP, as
in effect from time to time; provided, however, that for purposes of
determining compliance with any covenant set forth in Article V, such terms
shall be construed in accordance with GAAP as in effect on the date hereof
applied on a basis consistent with the application used in preparing the
Borrowers' audited financial statements referred to in Section 3.05.


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, (a) to make a Term Loan
to TU on the Effective Date in a principal amount not to exceed its Term Loan
Commitment, and (b) to make Standby Loans to each Borrower, at any time and
from time to time on and after the date hereof and until the earlier of the
Maturity Date and the termination
   29
                                                                              25


of the Standby Commitment of such Lender, in an aggregate principal amount at
any time outstanding not to exceed such Lender's Standby Commitment minus the
amount by which the Competitive Loans made to such Borrower and outstanding at
such time shall be deemed to have used such Standby Commitment pursuant to
Section 2.14, subject, however, to the conditions that (i) at no time shall (A)
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 (B) the Total Standby Commitment, (ii) at no time shall (A) the sum of
(x) the outstanding aggregate principal amount of all Standby Loans to TU plus
(y) the outstanding aggregate principal amount of all Competitive Loans to TU
plus (z) the outstanding aggregate principal amount of all Loans to TU under
and as defined in the Facility A Credit Agreement exceed (B) 60% of the sum of
the Total Standby Commitment hereunder and the Total Commitment under and as
defined in the Facility A Credit Agreement, (iii) at no time shall the
outstanding aggregate principal amount of all Standby Loans made by any Lender
exceed the amount of such Lender's Standby Commitment and (iv) at all times,
the outstanding aggregate principal amount of all Standby Loans made by each
Lender to each Borrower shall equal the product of (A) the percentage which
such Lender's Standby Commitment represents of the Total Standby 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.  Amounts paid or prepaid in respect of Term Loans
may not be reborrowed.

                 SECTION 2.02.  Loans.  (a)  Each Standby Loan or Term Loan
shall be made as part of a Borrowing consisting of Loans made by the Lenders
ratably in accordance with their respective Standby Commitments or Term Loan
Commitments, as the case may be; provided, however, that the failure of any
Lender to make any Standby Loan or Term 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, Term Loans or Competitive Loans comprising any Borrowing shall
be (i) in the case of Competitive Loans, in an aggregate
   30
                                                                              26


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 and Term Loans, in an
aggregate principal amount which is an integral multiple of $5,000,000 and not
less than $10,000,000 (or an aggregate principal amount equal to the remaining
balance of the available Standby Commitments or the outstanding Term Loans, as
the case may be).

                 (b)  Each Competitive Borrowing shall be comprised entirely of
Eurodollar Competitive Loans or Fixed Rate Loans, and each other Borrowing
shall be comprised entirely of Eurodollar Loans or ABR Loans, as the applicable
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 11:00 a.m., 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 and Term 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
   31
                                                                              27


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 (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)  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.

                 (e)  TU shall have the right at any time upon prior
irrevocable notice to the Administrative Agent (i) not later than 10:00 a.m.,
Houston time, on the day of conversion, to convert any Eurodollar Term
Borrowing into an ABR Term Borrowing, (ii) not later than 10:00 a.m., Houston
time, three Business Days prior to conversion or continuation, to convert any
ABR Term Borrowing into a Eurodollar Term Borrowing or to continue any
Eurodollar Term Borrowing as a Eurodollar Term Borrowing for an additional
Interest Period, and (iii) not later than 10:00 a.m., Houston time, three
Business Days prior to conversion, to convert the Interest Period with respect
to any Eurodollar Term Borrowing to another permissible Interest Period,
subject in each case to the following:

                  (i) each conversion or continuation shall be made pro rata
         among the Lenders in accordance with the respective principal amounts
         of the Term Loans comprising the converted or continued Term
         Borrowing;

                  (ii) if less than all the outstanding principal amount of any
         Term Borrowing shall be converted or
   32
                                                                              28


         continued, then each resulting Term Borrowing shall satisfy the
         limitations specified in Section 2.02(a) regarding the principal
         amount of Term Borrowings of the relevant Type;

                  (iii) each conversion shall be effected by each Lender and
         the Administrative Agent by recording for the account of such Lender
         the new Term Loan of such Lender resulting from such conversion and
         reducing the Term Loan (or portion thereof) of such Lender being
         converted by an equivalent principal amount; accrued interest on any
         Eurodollar Term Loan (or portion thereof) being converted shall be
         paid by TU at the time of conversion;

                  (iv) if any Eurodollar Term Borrowing is converted at a time
         other than the end of the Interest Period applicable thereto, TU shall
         pay, upon demand, any amounts due to the Lenders pursuant to Section
         8.05;

                 (v) any portion of a Term Borrowing maturing in less than
         seven days may not be converted into or continued as a Eurodollar Term
         Borrowing;

                 (vi) any portion of a Eurodollar Term Borrowing that cannot be
         converted into or continued as a Eurodollar Term Borrowing by reason
         of the immediately preceding clause shall be automatically converted
         at the end of the Interest Period in effect for such Term Borrowing
         into an ABR Term Borrowing;

                 (vii) no Interest Period may be selected for any Eurodollar
         Term Borrowing that would end later than the Maturity Date; and

                 (viii) upon notice to TU from the Administrative Agent given
         at the request of the Required Lenders, after the occurrence and
         during the continuance of a Default or Event of Default, no
         outstanding Term Loan may be converted into, or continued as, a
         Eurodollar Term Loan.

                 Each notice pursuant to this Section 2.02(e) shall be
irrevocable and shall refer to this Agreement and specify (i) the identity and
amount of the Term Borrowing that TU requests be converted or continued, (ii)
whether such Term Borrowing is to be converted to or continued as a Eurodollar
Term Borrowing or an ABR Term Borrowing, (iii) if such notice requests a
conversion, the date of such conversion (which shall be a Business Day) and
(iv) if such Term Borrowing is to
   33
                                                                              29


be converted to or continued as a Eurodollar Term Borrowing, the Interest
Period with respect thereto.  If no Interest Period is specified in any such
notice with respect to any conversion to or continuation as a Eurodollar Term
Borrowing, TU shall be deemed to have selected an Interest Period of one
month's duration.  The Administrative Agent shall advise the Lenders of any
notice given pursuant to this Section 2.02(e) and of each Lender's portion of
any converted or continued Term Borrowing.  If TU shall not have given notice
in accordance with this Section 2.02(e) to continue any Term Borrowing into a
subsequent Interest Period (and shall not otherwise have given notice in
accordance with this Section 2.02(e) to convert such Term Borrowing), such Term
Borrowing shall, at the end of the Interest Period applicable thereto (unless
repaid pursuant to the terms hereof), automatically be continued into a new
Interest Period as an ABR Term Borrowing.  TU shall not have the right to
continue or convert the Interest Period with respect to any Standby Borrowing
or Competitive Borrowing pursuant to this Section 2.02(e).

                 SECTION 2.03.  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 (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 (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,
   34
                                                                              30


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 (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
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 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
   35
                                                                              31


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 (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 such Borrower to give such notice
shall be deemed to be a rejection of all the bids referred to in paragraph (c)
above, (ii) 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, (iii) the aggregate amount of the Competitive Bids
accepted by such Borrower shall not exceed the principal amount specified in
the Competitive Bid Request, (iv) 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
(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 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
   36
                                                                              32


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
paragraph (i) or (ii) 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 2.04.  Borrowing Procedure.  In order to request a
Term Borrowing or a Standby Borrowing, a Borrower shall hand deliver or
telecopy to the Administrative Agent a duly completed Borrowing Request in the
form of Exhibit A-5 (a) in the case of a Eurodollar 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, on the
day of such Borrowing.  No Fixed Rate Loan shall be requested or made pursuant
to a Borrowing Request.  Such notice shall be irrevocable and shall in each
case specify (i) whether the Borrowing then being
   37
                                                                              33


requested is to be a Term Borrowing or a Standby Borrowing, and whether such
Borrowing is to be a Eurodollar 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 Borrowing, the Interest
Period with respect thereto, which shall not end after the Maturity Date.  If
no election as to the Type of Borrowing is specified in any such notice, then
the requested Borrowing shall be an ABR Borrowing.  If no Interest Period with
respect to any Eurodollar Borrowing is specified in any such notice, then the
Borrower shall be deemed to have selected an Interest Period of one month's
duration.  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 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)  TU agrees to pay (and TU Electric
agrees to pay, to the extent that TU shall not have paid all such fees, up to
the amount of its Fee Share (without duplication) from time to time) 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 June 30, 1996) and on
each date on which the Standby 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
Standby Commitment of such Lender, whether used or unused, during the preceding
quarter (or other period commencing on the Effective Date or ending with the
Maturity Date or any date on which the Standby 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 Standby Commitment of such Lender as provided herein.
   38
                                                                              34


                 (b)  TU agrees (and TU Electric agrees, to the extent that TU
shall not have paid such fees, up to the amount of its Fee Share from time to
time) to pay the Administrative Agent, for its own account, the administrative
and other fees provided for in the Fee Letter (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 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 Standby Loan and each
Competitive Loan shall be due and payable on the earlier of the last day of the
Interest Period applicable thereto and the Maturity Date and the outstanding
principal balance of each Term Loan shall be due and payable 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, (ii) the amount of any
principal or interest due and payable or to become due and payable from each
Borrower to each Lender hereunder and (iii) 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.
   39
                                                                              35



                 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 (i) in the case of each
Eurodollar Standby Loan and each Eurodollar Term Loan made to TU, the LIBO Rate
for the Interest Period in effect for such Borrowing plus the TU Applicable
Margin from time to time in effect, (ii) in the case of each Eurodollar Standby
Loan made to TU Electric, the LIBO Rate for the Interest Period in effect for
such Borrowing plus the TU Electric Applicable Margin from time to time in
effect and (iii) 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.

                 (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)  The interest rate applicable to each Eurodollar Loan made
to TU shall be increased by 0.10% per annum for each day on which Indebtedness
of TU in excess of that permitted under Section 5.13 (without giving effect to
the proviso therein) shall be outstanding.

                 (e)  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 Chemical, and such determination shall be conclusive absent
manifest error; provided that Chemical  shall, upon request, provide to the
applicable Borrower a
   40
                                                                              36


certificate setting forth in reasonable detail the basis for such
determination.

                 SECTION 2.08.  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 Agent 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 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
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 or a Eurodollar Term Borrowing pursuant to Section
2.02 or 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
   41
                                                                              37


applicable Borrower a certificate setting forth in reasonable detail the basis
for such determination.

                 SECTION 2.10.  Termination and Reduction of Commitments.  (a)
The Term Loan Commitments shall automatically terminate at 5:00 p.m., New York
City time, on the Effective Date.  The Standby Commitments shall automatically
terminate at 5:00 p.m., New York City time, on the Maturity Date.

                 (b)  Upon at least three 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 Term Loan Commitments or the Standby Commitments;
provided, however, that (i) each partial reduction of the Term Loan Commitments
or the Standby Commitments shall be in an integral multiple of $5,000,000 and
in a minimum principal amount of $5,000,000 and (ii) no such termination or
reduction shall be made which would reduce the Total Standby 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
Standby Commitment to $0.  The Administrative Agent shall advise the Lenders of
any notice given pursuant to this Section 2.10(b) and of each Lender's portion
of any such termination or reduction of the Term Loan Commitments or the
Standby Commitments.

                 (c)  Each reduction in the Term Loan Commitments or the
Standby Commitments hereunder shall be made ratably among the Lenders in
accordance with their respective applicable Commitments.  The Borrowers shall
pay to the Administrative Agent for the account of the Lenders, on the date of
each termination or reduction, 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 and any
Term 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,
   42
                                                                              38


that each partial prepayment shall be in an amount which is an integral
multiple of $5,000,000 and not less than $5,000,000.  No prepayment may be made
in respect of any Competitive Borrowing.

                 (b)  On the date of any termination or reduction of the
Standby 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 Standby 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
   43
                                                                              39


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.

                 (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
   44
                                                                              40


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
(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 Borrowers and to the Agents, such Lender may:
   45
                                                                              41


                 (i) declare that Eurodollar Loans will not thereafter be made
         by such Lender hereunder (or be continued for additional Interest
         Periods) and that ABR Loans will not thereafter be converted into
         Eurodollar Loans, whereupon such Lender shall not submit a Competitive
         Bid in response to a request for Eurodollar Competitive Loans and any
         request for a Eurodollar Borrowing (or to convert an ABR Borrowing to
         a Eurodollar Borrowing or to continue a Eurodollar Borrowing for an
         additional Interest Period) shall, as to such Lender only, be deemed a
         request for an ABR Loan (or a request to continue an ABR Loan as such
         for an additional Interest Period or to convert a Eurodollar Loan into
         an ABR Loan, as the case may be), 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 Borrowing, each payment or prepayment of
principal of any Borrowing, each payment of interest on the Loans, each payment
of the Facility Fees, each reduction of the Term Loan Commitments or the
Standby Commitments and each refinancing or conversion of any Borrowing to or
continuation of any Borrowing as a Borrowing of any Type, shall be
   46
                                                                              42


allocated pro rata among the Lenders in accordance with their respective
applicable Commitments (or, if such Commitments shall have expired or been
terminated, in accordance with the respective principal amounts of their
applicable outstanding 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 Standby
Commitments of the Lenders at any time, each outstanding Competitive Borrowing
shall be deemed to have utilized the Standby 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 Standby
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 Loan or
Loans as a result of which the unpaid principal portion of its Term Loans and
Standby Loans shall be proportionately less than the unpaid principal portion
of the Term Loans and 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 Term Loans and Standby Loans, as the case may be, of such other Lender,
so that the aggregate unpaid principal amount of the Term Loans and Standby
Loans and participations in the Term Loans and Standby Loans held by each
Lender shall be in the same proportion to the aggregate unpaid principal amount
of all Term Loans and Standby Loans then outstanding as the principal amount of
its Term Loans and Standby Loans prior to such exercise of banker's lien,
setoff
   47
                                                                              43


or counterclaim or other event was to the principal amount of all Term Loans
and 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 Term Loan or 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 Term Loan or
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 1111 Fannin Street, 9th floor, MS 46, 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
   48
                                                                              44


"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 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, (ii) such Borrower shall make such deductions
and (iii) 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 Fee Letter ("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
   49
                                                                              45


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
   50
                                                                              46


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 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
   51
                                                                              47


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.

                 (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 Interests 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
   52
                                                                              48


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 (ii) 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.

   53
                                                                              49

                 (c)  Since December 31, 1995, there has been no Material

                 SECTION 3.06.  Litigation; Compliance with Laws. Except as set
forth in 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 or as set forth on Schedule 3.06, there is no action, suit or
proceeding pending against, or to the knowledge of such Borrower threatened
against or affecting, TU or any of its Subsidiaries before any court or
arbitrator or
   54
                                                                              50


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 3.07.  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 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.

                 SECTION 3.08.  Investment Company Act; Public Utility Holding
Company Act.  (a) Neither such Borrower nor any of its Subsidiaries is an
"investment company" as defined in, or subject to regulation under, the
Investment Company Act of 1940.

                 (b)  Such Borrower and each of its Subsidiaries is exempt from
all provisions of the Public Utility Holding Company Act of 1935 and 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 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 3.09.  No Material Misstatements.  No report,
financial statement or other information furnished by or on behalf of such
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.  Such Borrower and its Subsidiaries have
filed or caused to be filed within 3 days of the date on which due, all
Federal, state and material local tax returns which to their knowledge are
required to be filed
   55
                                                                              51


by them, and have paid or caused to be paid all taxes shown to be due and
payable on such returns or on any assessments received by them, other than any
taxes or assessments the validity of which is being contested in good faith by
appropriate proceedings and with respect to which appropriate accounting
reserves have to the extent required by GAAP been set aside.

                 SECTION 3.11.  Employee Benefit Plans.  With respect to each
Plan such Borrower and its ERISA Affiliates are in compliance in all material
respects with the applicable provisions of ERISA and the Code and the final
regulations and published interpretations thereunder.  No ERISA Event has
occurred in respect of any Plan of such Borrower or any ERISA Affiliate that
alone or together with any other ERISA Event has resulted or could reasonably
be expected to result in a Material Adverse Change.  The present value of all
accrued benefit obligations determined on a termination basis under each of its
Plans (based on those assumptions used to fund such Plans) did not, as of the
last annual valuation date applicable thereto, exceed by more than 5% of the
amount of such obligations the value of the assets of such Plan, and the
present value of all accrued benefit obligations of all underfunded Plans
(based on those assumptions used to fund each such Plan) did not, as of the
last annual valuation dates applicable thereto, exceed by more than the lesser
of (i) 5% of the amount all such liabilities and (ii) $100,000,000, the value
of the assets of all such underfunded Plans.  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.

                 SECTION 3.12.  Significant Subsidiaries.  Each of TU's
corporate Significant Subsidiaries is a corporation duly incorporated, validly
existing and in good standing under the laws of its jurisdiction of
incorporation and has all corporate powers necessary to carry on its business
substantially as now conducted.  TU's corporate Significant
   56
                                                                              52


Subsidiaries have all material governmental licenses, authorizations, consents
and approvals required to carry on the business of the corporate Significant
Subsidiaries substantially as now conducted.

                 SECTION 3.13.  Environmental Matters.  Except as set forth in
or 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, 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
pollutants or substances similarly denominated, as those terms or similar terms
are used in the Resource Conservation and Recovery Act, the Comprehensive
Environmental Response Compensation and Liability Act, the Hazardous Materials
Transportation Act, the Toxic Substance Control Act, the Clean Air Act, the
Clean Water Act or any other applicable law relating to environmental
pollution, or any nuclear fuel or other radioactive materials, in violation in
any material respect of any law or any regulations promulgated pursuant
thereto, except to the extent that such violations 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, such 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.
   57
                                                                              53


ARTICLE IV.  CONDITIONS OF LENDING

                 The obligations of the Lenders to make Loans hereunder are
subject to the satisfaction of the following conditions:

                 SECTION 4.01.  All Borrowings.  On the date of each Borrowing:

                 (a)  The Agents shall have received a notice of such Borrowing
         as required by Section 2.03 or Section 2.04, as applicable.

                 (b)  The representations and warranties set forth in Article
         III hereof (except, in the case of a refinancing of a Standby
         Borrowing with a new Standby Borrowing that does not increase the
         aggregate principal amount of the Loans of any Lender outstanding, the
         representations set forth in Sections 3.05(c), 3.06, 3.11 and 3.13)
         shall be true and correct in all material respects on and as of the
         date of such Borrowing with the same effect as though made on and as
         of such date, except to the extent such representations and warranties
         expressly relate to an earlier date.

                 (c)  At the time of and immediately after such Borrowing no
         Event of Default or Default shall have occurred and be continuing.

Each Borrowing shall be deemed to constitute a representation and warranty by
each Borrower on the date of such Borrowing as to the matters specified in
paragraphs (b) and (c) of this Section 4.01.

                 SECTION 4.02.  Effective Date.  On the Effective Date:

                 (a)  The Agents shall have received favorable written opinions

         incurred prior to, at the time of, or within 90 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

                 secured by all Liens in respect of any such property shall not
                 exceed the cost or fair market value (both as determined by
                 the board of directors of TU or such Significant Subsidiary,
                 as the case may be), whichever shall be lower, of such
                 property at the time of acquisition thereof (or (x) in the

                 value, as so determined, of such property at the time of such
                 transaction, or (y) in the case of a Lien in respect of

                 TU or by such Subsidiary, or at the time such corporation
                 becomes a Subsidiary of TU, as the case may be, every such
                 Lien shall apply and attach only to the property originally
                 subject thereto and fixed improvements constructed thereon; or

                 (c) refundings or extensions of any Lien permitted in the
         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 TU 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

         sold or delivered by TU or any Significant Subsidiary; or
   66
                                                                              62

assume or permit to exist Indebtedness (other than guarantees existing as of
the date hereof and guarantees of any obligations of Subsidiaries) in an amount
at any time in excess of the sum at such time of (a) $1,500,000,000, (b) if

the Lenders pursuant to Section 5.03 over (ii) the aggregate amount of
dividends paid by TU after the Effective Date and (c) the aggregate proceeds

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 Borrowers 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 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
   72
                                                                              68


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 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.
   73
                                                                              69


                 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 (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
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
   74
                                                                              70

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 Borrowers and the Agents to such assignment, the Administrative Agent shall
(i) accept such Assignment and Acceptance and (ii) record the information
contained therein in the Register.

                                                                              74


                 (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, (ii)
such Lender shall remain solely responsible to the other parties hereto for the
performance of such obligations, (iii) 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 (iv) 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.

                 (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

                                                                              75


or notes evidencing the Loans made to such Borrower by the assigning Lender
hereunder.

                 SECTION 8.05.  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 2.02(e), 2.03 or 2.04, (b) 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, (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
   80
                                                                              76


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 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, (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; 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 Borrowers or by any Borrower against such Indemnitee, in
which a final, nonappealable judgment has been rendered against such
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
   81
                                                                              77


determined shall be delivered to the appropriate 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 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.

                 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 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
   82
                                                                              78


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, (iii) increase the percentage set forth
in clause (b)(ii)(B) of Section 2.01, without the prior written consent of each
Lender, or (iv) 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 Fee Letter constitute a "Loan
Agreement" as defined in Section 26.03(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 among the parties
with respect to the subject matter hereof is superseded by this Agreement and
the Fee Letter.  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
   83
                                                                              79


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
   84
                                                                              80


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, (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 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 (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 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.
   85
                                                                              81


                 SECTION 8.16.  Transition Period.  At all times following
April 23, 1996, and prior to the Effective Date, the provisions of this
Agreement in effect prior to the amendment and restatement hereof executed and
delivered as of April 23, 1996, shall remain in effect without modification,
except that (i) the provisions of Section 8.05 shall apply to all parties
signatory hereto (in addition to all persons that are Lenders prior to giving
effect to such amendment and restatement) and to each Borrowing Request
delivered on April 23, 1996 and (ii) each Borrowing Request delivered on April
23, 1996 shall be deemed given solely to the parties signatory hereto and
subject to the provisions hereof as such provisions would be in effect after
the Effective Date.


                 IN WITNESS WHEREOF, the parties hereto have caused this
Agreement to be duly executed by their respective authorized officers as of the
day and year first above written.

                                 April 26, 1996

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

Ladies and Gentlemen:

         We advise you that we have acted as counsel to Texas Utilities
Company, a Texas corporation (TU), and Texas Utilities Electric Company, a
Texas corporation (TU Electric), in connection with the Amended and Restated
Competitive Advance and Revolving Credit Facility Agreement and the Amended and
Restated Term Loan and Competitive Advance and Revolving Credit Facility
Agreement (Credit Agreements), each dated as of April 26, 1996, among TU, TU
Electric, Texas Commerce Bank National Association, as Administrative Agent,
Chemical Bank, as Competitive Advance Facility Agent, and the banks listed on
Schedule 2.01 thereof (Lenders), and have participated in the preparation of or
have examined and are familiar with (a) the current financial statements and
reports filed by TU and TU Electric 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 TU and TU Electric
and (d) such other records and documents as we have deemed necessary for the
purposes of this opinion.

         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 4.02(a) of the Credit
Agreements.

         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 TU and TU Electric 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.

         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 TU and TU Electric, 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 TU and TU Electric. While we represent
TU and TU Electric on a regular basis, our engagement has been limited to
specific matters as to which we were consulted.
   107
                                      -2-

We have no direct knowledge of the day-to-day affairs of TU or TU Electric and
have not reviewed generally their business affairs. Accordingly, we are relying
upon representations of TU and TU Electric contained in the Credit Agreements,
in certificates furnished pursuant thereto, and in certificates  furnished to
us by officers of TU and TU Electric.

         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 TU and TU Electric, (iv)
the legal capacity of natural persons, (v) the power, corporate or otherwise,
of all parties other than TU and TU Electric 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 TU and TU
Electric.

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

         1.      Each of TU and TU Electric (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 TU and TU
Electric of the Credit Agreements and the Borrowings by each of them thereunder
(collectively, the "Transactions") (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 either TU or TU
Electric, or the articles of incorporation, as amended, or by-laws of either TU
or TU Electric, (2) to our knowledge, any order of any Governmental Authority
presently applicable to either TU or TU Electric or (3) any provision of any
indenture, agreement or other instrument known to us to which either TU or TU
Electric is a party or by which either TU or TU Electric 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 of either TU or TU
Electric.

         3.      The Credit Agreements have been duly executed and delivered by
TU and TU Electric and constitute legal, valid and binding obligations of TU
and TU Electric 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.)
   108
                                      -3-

         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 either TU or TU Electric in connection with the Transactions, except
such as have been made or obtained and are in full force and effect.

         5.      (a) Neither TU nor TU Electric 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) TU, 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 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 TU and TU Electric of the Credit Agreements do not violate any
provisions of such Act or any rule or regulation thereunder.

         6.      Except as described in the Annual Reports of TU and TU
Electric on Form 10-K for the year ended December 31, 1995 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 either TU or TU
Electric (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.

         This letter is solely for the benefit of the named addresses 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 Worsham, Forsythe & Wooldridge, L.L.P. may rely hereon in
connection with their opinion being rendered pursuant to Section 4.02(a) of the
Credit Agreements.


                                        Very truly yours,

                                                                     EXHIBIT D-2

                                                             April 26, 1996


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 (TU) and Texas Utilities Electric Company, a Texas corporation (TU
Electric), in connection with the execution and delivery of the Amended and
Restated Competitive Advance and Revolving Credit Facility Agreement and the
Amended and Restated Term Loan and Competitive Advance and Revolving Credit
Facility Agreement (Credit Agreements), each dated as of April 26, 1996, among
TU, TU Electric, the banks listed on Schedule 2.01 thereof (Lenders), Texas

         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 4.02(a) of the Credit
Agreements.

         In connection with this opinion we have examined a counterpart of the
Credit Agreements executed by TU and TU Electric and have also made such
examination of other documents and of certificates of public officials and
corporate officers of TU and TU Electric, 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 TU and TU Electric 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.
   110
                                      -2-

         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 TU and TU Electric, (iv)
the legal capacity of natural persons, (v) the power, corporate or otherwise,
of all parties other than TU and TU Electric to enter into and to perform all

execution and delivery of all documents by all parties other than TU and TU
Electric.

         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 TU and TU Electric (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

Agreements and to borrow funds thereunder.

         2.      The execution, delivery and performance by each of TU and TU
Electric of the Credit Agreements and the Borrowings by each of them thereunder
(collectively, the Transactions") (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 either TU or TU
Electric, or the articles of incorporation, as amended, or by-laws of either TU
or TU Electric, (2) to our knowledge, any order of any Governmental Authority
presently applicable to either TU or TU Electric or (3) any provision of any
indenture, agreement or other instrument known to us to which either TU or TU
Electric is a party or by which either TU or TU Electric 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 either TU or TU Electric.

         3.      The Credit Agreements have been duly executed and delivered by
TU and TU Electric and constitute legal, valid and binding obligations of TU
and TU Electric 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 Government Authority (including pursuant to
the Public Utility Holding Company Act of 1935, as amended) is or will be
required on the part of either TU or TU Electric in connection with the
Transactions, except such as have been made or obtained and are in full force
and effect.
   111
                                      -3-

         5.      Neither TU nor TU Electric 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. TU, 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 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
TU and TU Electric of the Credit Agreements do not violate any provision of
such Act or any rule or regulation thereunder.

         6.      Except as described in the Annual Reports of TU and TU
Electric on Form 10-K for the year ended December 31, 1995 and as set forth in
