This prospectus provides you with a general description of the securities we may
offer. Each time we sell securities, we will provide a prospectus supplement
that will contain specific information about the terms of that offering. The
prospectus supplement may also add, update or change information contained in
this prospectus. You should read both this prospectus and any prospectus
supplement together with additional information described under the heading

      ( )  If the debt securities will be issued in denominations other than
           $1,000;

      ( )  If payments on the debt securities may be made in a currency or
           currencies other than United States dollars; and

      ( )  Any other terms of the debt securities not inconsistent with the
           terms of the indenture (Indenture, Section 301).

      The indenture does not limit the principal amount of debt securities that
TXU Gas Company may issue.

      TXU Gas Company may sell debt securities at a discount below their
principal amount. United States federal income tax considerations applicable to
debt securities sold at an original issue discount may be described in the
prospectus supplement. In addition, important United States federal income tax
or other tax considerations applicable to any debt securities denominated or
payable in a currency or currency unit other than United States dollars may be
described in the prospectus supplement.

      Except as may otherwise be described in the applicable prospectus
supplement, the covenants contained in the indenture will not afford holders of
debt securities protection in the event of a highly-leveraged transaction
involving TXU Gas Company.

      PAYMENT AND PAYING AGENTS

      Except as may be provided in the prospectus supplement, interest, if any,
on each debt security payable on each interest payment date will be paid to the
person in whose name that debt security is registered as of the close of
business on the regular record date for the interest payment date. However,
interest payable at maturity will be paid to the person to whom the principal is
paid. If there has been a default in the payment of interest on any debt
security, the defaulted interest may be paid to the holder of the debt security
as of the close of business on a date between 10 and 15 days before the date
proposed by TXU Gas Company for payment of defaulted interest or in any other
manner permitted by any securities exchange on which that debt security may be
listed, if the trustee finds it workable (Indenture, Section 307).

      Unless otherwise specified in the prospectus supplement, principal,
premium, if any, and interest on the debt securities at maturity will be payable
upon presentation of the debt securities at the corporate trust office of The
Bank of New York, in The City of New York, as paying agent for TXU Gas Company.
TXU Gas Company may change the place of payment on the debt securities, may
appoint one or more additional paying agents, including TXU Gas Company, and may
remove any paying agent, all at the discretion of TXU Gas Company (Indenture,
Section 602).


                                    -5-

      REGISTRATION AND TRANSFER

      Unless otherwise specified in the prospectus supplement, the transfer of
debt securities may be registered, and debt securities may be exchanged for
other debt securities of the same series or tranche, of authorized denominations
and with the same terms and principal amount, at the corporate trust office of
The Bank of New York in The City of New York. TXU Gas Company may change the
place for registration of transfer and exchange of the debt securities and may
designate additional places for registration and exchange (Indenture, Section
602). Unless otherwise provided in the prospectus supplement, no service charge
will be made for any transfer or exchange of the debt securities. However, TXU
Gas Company may require payment to cover any tax or other governmental charge
that may be imposed. TXU Gas Company will not be required to execute or to
provide for the registration of transfer of, or the exchange of, (a) any debt
security during the 15 days before giving any notice of redemption or (b) any
debt security selected for redemption except the unredeemed portion of any debt
security being redeemed in part (Indenture, Section 305).

      DEFEASANCE

      TXU Gas Company will be discharged from its obligations on the debt
securities of a particular series if it deposits with the trustee sufficient
cash or government securities to pay the principal, interest, any premium and
any other sums when due on the stated maturity date or a redemption date of that
series of debt securities (Indenture, Section 701).

      CONSOLIDATION, MERGER, AND SALE OF ASSETS

      Under the terms of the indenture, TXU Gas Company may not consolidate with
or merge into any other entity or convey, transfer or lease its properties and
assets substantially as an entirety to any entity, unless:

      ( )  The surviving or successor entity is organized and validly existing
           under the laws of any domestic jurisdiction and it expressly assumes
           TXU Gas Company's obligations on all debt securities and under the
           indenture;

      ( )  Immediately after giving effect to the transaction, no Event of
           Default under the indenture or no event which, after notice or lapse
           of time or both, would become an Event of Default under the
           indenture, will have occurred and be continuing; and

      ( )  TXU Gas Company will have delivered to the trustee an officer's
           certificate and an opinion of counsel as provided in the indenture
           (Indenture, Section 1101).

      The terms of the indenture do not restrict TXU Gas Company in a merger in
which TXU Gas Company is the surviving entity.

      EVENTS OF DEFAULT

      "Event of Default", when used in the indenture with respect to debt
securities of a specific series, means any of the following:

      ( )  Failure to pay interest on any debt security of that series for 30
           days after it is due;

      ( )  Failure to pay the principal of or any premium on any debt security
           of that series when due;

      ( )  Failure to perform any other covenant in the indenture, other than a
           covenant that does not relate to the debt securities of that series,
           for 90 days after TXU Gas Company receives written notice from the
           trustee


                                    -6-
<PAGE>


           or TXU Gas Company and the trustee receive written notice from the
           holders of 33% in aggregate principal amount of the debt securities;

      ( )  Events in bankruptcy, insolvency or reorganization of TXU Gas Company
           specified in the indenture; or

      ( )  Any other Event of Default included in any supplemental indenture or
           officer's certificate for that series of debt securities (Indenture,
           Section 801).

      An Event of Default for a particular series of debt securities does not
necessarily constitute an Event of Default for any other series of debt
securities issued under the indenture. The trustee may withhold notice to the
holders of debt securities of any default, except default in the payment of
principal or interest, if it considers the withholding of notice to be in the
interests of the holders.

      REMEDIES

      If an Event of Default for any series of debt securities occurs and
continues, the trustee or the holders of at least 33% in aggregate principal
amount of all the debt securities of the series may declare the entire principal
amount of all the debt securities of that series, together with accrued
interest, to be due and payable immediately. However, if the Event of Default is
applicable to all outstanding debt securities under the indenture, only the
trustee or holders of at least 33% in aggregate principal amount of all
outstanding debt securities of all series, voting as one class, and not the
holders of any one series, may make that declaration of acceleration (Indenture,
Section 802).

      At any time after a declaration of acceleration with respect to the debt
securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained, the Event of Default giving rise to
the declaration of acceleration will be considered waived, and the declaration
and its consequences will be considered rescinded and annulled, if:

      ( ) TXU Gas Company has paid or deposited with the trustee a sum
          sufficient to pay:

           (1)             all overdue interest on all debt securities of the
                           series;

           (2)             the principal of and premium, if any, on any debt
                           securities of the series which have otherwise
                           become due and interest that is currently due;

           (3)             interest on overdue interest; and

           (4)             all amounts due to the trustee under the indenture;
                           and

      ( )  Any other Event of Default with respect to the debt securities of
           that series has been cured or waived as provided in the indenture
           (Indenture, Section 802).

      There is no automatic acceleration, even in the event of bankruptcy,
insolvency or reorganization of TXU Gas Company.

      Other than its duties in case of an Event of Default, the trustee is not
obligated to exercise any of its rights or powers under the indenture at the
request, order or direction of any of the holders, unless the holders offer the
trustee a reasonable indemnity (Indenture, Section 903). If they provide this
reasonable indemnity, the holders of a majority in principal amount of any
series of debt securities will have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the trustee, or
exercising any power conferred upon the trustee. However, if the Event of
Default relates to more than one series, only the holders of a majority in
aggregate principal amount of all affected series will have the right to give
this direction (Indenture, Section 812). The trustee is not obligated to comply
with directions that conflict with law or other provisions of the indenture.


                                    -7-
<PAGE>


      No holder of debt securities of any series will have any right to
institute any proceeding under the indenture, or any remedy under the indenture,
unless:

      ( )  The holder has previously given to the trustee written notice of a
           continuing Event of Default;

      ( )  The holders of a majority in aggregate principal amount of the
           outstanding debt securities of all series in respect of which an
           Event of Default has occurred and is continuing have made a written
           request to the trustee, and have offered reasonable indemnity to the
           trustee to institute proceedings; and

      ( )  The trustee has failed to institute any proceeding for 60 days after
           notice (Indenture, Section 807).

However, these limitations do not apply to a suit by a holder of a debt security
for payment of the principal, premium, if any, or interest on the debt security
on or after the applicable due date (Indenture, Section 808).

      TXU Gas Company will provide to the trustee an annual statement by an
appropriate officer as to TXU Gas Company's compliance with all conditions and
covenants under the indenture (Indenture, Section 606).

      MODIFICATION AND WAIVER

      Without the consent of any holder of debt securities issued under an
indenture, TXU Gas Company and the trustee may enter into one or more
supplemental indentures for any of the following purposes:

      ( )  To evidence the assumption by any permitted successor of the
           covenants of TXU Gas Company in the indenture and in the debt
           securities;

      ( )  To add additional covenants of TXU Gas Company or to surrender any
           right or power of TXU Gas Company under the indenture;

      ( )  To add additional Events of Default;

      ( )  To change or eliminate or add any provision to the indenture;
           provided, however, if the change will adversely affect the interests
           of the holders of debt securities of any series in any material
           respect, the change, elimination or addition will become effective
           only:

           (1)   when the consent of the holders of debt securities of that
                 series has been obtained in accordance with the indenture; or

           (2)   when no debt securities of the affected series remain
                 outstanding under the indenture;

      ( )  To provide collateral security for all but not part of the debt
           securities;

      ( )  To establish the form or terms of debt securities of any other series
           as permitted by the indenture;

      ( )  To provide for the authentication and delivery of bearer securities
           with or without coupons;

      ( )  To evidence and provide for the acceptance of appointment of a
           successor trustee;

      ( )  To provide for the procedures required for use of a noncertificated
           system of registration for the debt securities of all or any series;


                                     -8-
<PAGE>


      ( )  To change any place where principal, premium, if any, and interest
           will be payable, debt securities may be surrendered for registration
           of transfer or exchange and notices to TXU Gas Company may be served;
           or

      ( )  To cure any ambiguity or inconsistency or to make any other
           provisions with respect to matters and questions arising under the
           indenture; provided that the changes or additions do not adversely
           affect the interests of the holders of debt securities of any series
           in any material respect (Indenture, Section 1201).

      The holders of at least a majority in aggregate principal amount of the
debt securities of all series then outstanding may waive compliance by TXU Gas
Company with some restrictive provisions of the indenture (Indenture, Section
607). The holders of not less than a majority in principal amount of the
outstanding debt securities of any series may waive any past default under the
indenture with respect to that series, except a default in the payment of
principal, premium, if any, or interest and some covenants and provisions of the
indenture that cannot be modified or be amended without the consent of the
holder of each outstanding debt security of the series affected (Indenture,
Section 813).

      If the Trust Indenture Act is amended after the date of the indenture in a
way as to require changes to the indenture, the indenture will be deemed to be
amended so as to conform to that amendment to the Trust Indenture Act. TXU Gas
Company and the trustee may, without the consent of any holders, enter into one
or more supplemental indentures to evidence the amendment (Indenture, Section
1201).

      The consent of the holders of a majority in aggregate principal amount of
the debt securities of all series then outstanding is required for all other
modifications to the indenture. However, if less than all of the series of debt
securities outstanding are directly affected by a proposed supplemental
indenture, then the consent only of the holders of a majority in aggregate
principal amount of all series that are directly affected will be required. No
amendment or modification may:

      ( )  Change the stated maturity of the principal of, or any installment of
           principal of or interest on, any debt security, or reduce the
           principal amount of any debt security or its rate of interest or
           change the method of calculating the interest rate or reduce any
           premium payable upon redemption, or change the currency in which
           payments are made, or impair the right to institute suit for the
           enforcement of any payment on or after the stated maturity of any
           debt security, without the consent of the holder;

      ( )  Reduce the percentage in principal amount of the outstanding debt
           securities of any series whose consent is required for any
           supplemental indenture or any waiver of compliance with a provision
           of the indenture or any default thereunder and its consequences, or
           reduce the requirements for quorum or voting, without the consent of
           all the holders of the series; or

      ( )  Modify some of the provisions of the indenture relating to
           supplemental indentures, waivers of some covenants and waivers of
           past defaults with respect to the debt securities of any series,
           without the consent of the holder of each outstanding debt security
           affected by them (Indenture, Section 1202).

      A supplemental indenture which changes the indenture solely for the
benefit of one or more particular series of debt securities, or modifies the
rights of the holders of debt securities of one or more series, will not affect
the rights under the indenture of the holders of the debt securities of any
other series.

      The indenture provides that debt securities owned by TXU Gas Company or
anyone else required to make payment on the debt securities will be disregarded
and considered not to be outstanding in determining whether the required holders
have given a request or consent (Indenture, Section 101).

      TXU Gas Company may fix in advance a record date to determine the required
number of holders entitled to give any request, demand, authorization,
direction, notice, consent, waiver or other act of the holders, but TXU Gas


                                    -9-
<PAGE>


Company will have no obligation to do so. If TXU Gas Company fixes a record
date, that request, demand, authorization, direction, notice, consent, waiver or
other act of the holders may be given before or after that record date, but only
the holders of record at the close of business on that record date will be
considered holders for the purposes of determining whether holders of the
required percentage of the outstanding debt securities have authorized or agreed
or consented to the request, demand, authorization, direction, notice, consent,
waiver or other act of the holders. For that purpose, the outstanding debt
securities will be computed as of the record date. Any request, demand,
authorization, direction, notice, consent, election, waiver or other act of a
holder will bind every future holder of the same debt securities and the holder
of every debt security issued upon the registration of transfer of or in
exchange of these debt securities. A transferee will be bound by acts of the
trustee or TXU Gas Company in reliance on them, whether or not notation of that
action is made upon the debt security (Indenture, Section 104).

      RESIGNATION OF A TRUSTEE

      A trustee may resign at any time by giving written notice to TXU Gas
Company or may be removed at any time by act of the holders of a majority in
principal amount of all series of debt securities then outstanding delivered to
the trustee and TXU Gas Company. No resignation or removal of a trustee and no
appointment of a successor trustee will be effective until the acceptance of
appointment by a successor trustee. So long as no Event of Default or event
which, after notice or lapse of time, or both, would become an Event of Default
has occurred and is continuing and except with respect to a trustee appointed by
act of the holders, if TXU Gas Company has delivered to the trustee a resolution
of its Board of Directors appointing a successor trustee and that successor has
accepted the appointment in accordance with the terms of the respective
indenture, the trustee will be deemed to have resigned and the successor will be
deemed to have been appointed as trustee in accordance with the indenture
(Indenture, Section 910).

      NOTICES

      Notices to holders of debt securities will be given by mail to the
addresses of the holders as they may appear in the security register for debt
securities (Indenture, Section 106).

      TITLE

      TXU Gas Company, the trustee, and any agent of TXU Gas Company or the
trustee, may treat the person in whose name any debt security is registered as
the absolute owner of it, whether or not the debt security may be overdue, for
the purpose of making payments and for all other purposes irrespective of notice
to the contrary (Indenture, Section 308).

      GOVERNING LAW

      The indenture and the debt securities will be governed by, and construed
in accordance with, the laws of the State of New York (Indenture, Section 112).

      REGARDING THE TRUSTEE

      The trustee will be The Bank of New York. In addition to acting as
trustee, The Bank of New York acts, and may act, as trustee under various
indentures and trusts of TXU Gas Company, TXU Corp and other affiliates,
including the trust agreement for the preferred trust securities and the
indenture for the junior subordinated debentures described below. TXU Gas
Company, TXU Corp and other affiliates maintain deposit accounts and credit and
liquidity facilities and conduct other banking transactions with the trustee in
the ordinary course of their businesses.

     DESCRIPTION OF TXU GAS CAPITAL'S PREFERRED TRUST SECURITIES AND COMMON
                                TRUST SECURITIES

      TXU Gas Capital will issue preferred trust securities and common trust
securities under a trust agreement. The preferred trust securities will
represent preferred undivided beneficial interests in the assets of TXU Gas
Capital and will entitle their holders to a preference over the common trust
securities with respect to distributions and amounts payable on redemption or
liquidation. The material terms of the trust agreement are summarized
below. The form of trust agreement was filed with the SEC and you should read
the trust agreement for provisions that may be important to you. The trust
agreement will be qualified as an indenture under the Trust Indenture Act. You
should also refer to the Trust Indenture Act for provisions that apply to the
preferred trust securities. Wherever particular defined terms of the trust
agreement are referred to, those defined terms are incorporated in this
prospectus by reference.

      The preferred trust securities and common trust securities issued by TXU
Gas Capital will be substantially the same except that, if TXU Gas Capital fails
to make required payments, the rights of TXU Gas Company as the holder of the
common trust securities to payment of distributions and upon liquidation or
redemption will be subordinated to the rights of the holders of the preferred
trust securities. If there is a continuing Event of Default under the
subordinated indenture described below, holders of the preferred trust
securities may vote to appoint, remove or replace any of trustees of TXU Gas
Capital. All of the common trust securities of TXU Gas Capital will be owned by
TXU Gas Company.

      TXU Gas Capital will use the proceeds from the sale of the preferred trust
securities and common trust securities to purchase junior subordinated
debentures from TXU Gas Company in an aggregate principal amount equal to the
aggregate liquidation preference amount of the preferred trust securities and
the common trust securities. The junior subordinated debentures will be issued
under the Subordinated Indenture, dated June 1, 1998, between TXU Gas Company
and The Bank of New York, as debenture trustee. The property trustee will hold
the junior subordinated debentures in trust for the benefit of holders of the
preferred trust securities and common trust securities (Trust Agreement, Section
2.09).

      TXU Gas Company will fully and unconditionally guarantee payments due on
the preferred trust securities through a combination of the following:

      ( )  TXU Gas Company's obligations under the junior subordinated
           debentures;

      ( )  The rights of holders of preferred trust securities to enforce those
           obligations;

      ( )  TXU Gas Company's agreement to pay the expenses of TXU Gas Capital;
           or

      ( )  TXU Gas Company's guarantee of payments due on the preferred trust
           securities to the extent of TXU Gas Capital's assets.

      A prospectus supplement relating to the preferred trust securities will
include specific terms of those securities and of the junior subordinated
debentures. For a description of some specific terms that will affect both the
preferred trust securities and the junior subordinated debentures and your
rights under each, see DESCRIPTION OF THE JUNIOR SUBORDINATED DEBENTURES below.

      DISTRIBUTIONS

      The only income of TXU Gas Capital available for distribution to the
holders of preferred trust securities will be payments on the junior
subordinated debentures. If TXU Gas Company does not make interest payments on
the junior subordinated debentures, TXU Gas Capital will not have funds
available to pay distributions on preferred trust securities. The payment of


                                    -11-
<PAGE>


distributions, if and to the extent TXU Gas Capital has sufficient funds
available for the payment of those distributions, is guaranteed on a limited
basis by TXU Gas Company.

      So long as there is no default in the payment of interest on the junior
subordinated debentures, TXU Gas Company may extend the interest payment period
from time to time on the junior subordinated debentures for one or more periods.
As a consequence, distributions on preferred trust securities would be deferred
during any such period. Interest would, however, continue to accrue. If TXU Gas
Company extends the interest period or is in default under the guarantee or with
respect to payments on the junior subordinated debentures, TXU Gas Company may
not:

      ( )  Declare or pay any dividend or distribution on its capital stock,
           other than dividends paid in shares of common stock of TXU Gas
           Company;

      ( )  Redeem, purchase, acquire or make a liquidation payment with respect
           to any of its capital stock;

      ( )  Redeem any indebtedness that is equal in right of payment with the
           junior subordinated debentures; or

      ( )  Make any guarantee payments with respect to any of the above.

      Any extension period with respect to payment of interest on the junior
subordinated debentures, or any extended interest payment period in respect of
other securities issued under the subordinated indenture or on any similar
securities, will apply to all securities of the same type. Those extensions will
also apply to distributions on preferred trust securities and common trust
securities and all other securities with terms substantially the same as
preferred trust securities and common trust securities. Before an extension
period ends, TXU Gas Company may further extend the interest payment period. No
extension period as further extended may exceed 20 consecutive quarters. After
any extension period and the payment of all amounts then due, TXU Gas Company
may select a new extended interest payment period. No interest period may be
extended beyond the maturity of the junior subordinated debentures.

      REDEMPTION OF PREFERRED TRUST SECURITIES AND COMMON TRUST SECURITIES

      Whenever junior subordinated debentures are repaid, whether at maturity or
earlier redemption, the proceeds will be applied to redeem a like amount of
preferred trust securities and common trust securities. Holders of junior
subordinated debentures will be given not less than 30 nor more than 60 days'
notice of any redemption.

      REDEMPTION PROCEDURES

      Preferred trust securities will be redeemed at the redemption price plus
accrued and unpaid distributions with the proceeds from the contemporaneous
redemption of junior subordinated debentures. Redemptions of the preferred trust
securities will be made on a redemption date only if TXU Gas Capital has funds
available for the payment of the redemption price plus accrued and unpaid
distributions (Trust Agreement, Section 4.02(c)).

      Notice of redemption of preferred trust securities will be irrevocable. On
or before the redemption date, TXU Gas Capital will irrevocably deposit with the
paying agent for preferred trust securities sufficient funds and will give the
paying agent irrevocable instructions and authority to pay the redemption price
plus accrued and unpaid distributions to the holders upon surrender of their
preferred trust securities. Distributions payable on or before a redemption date
will be payable to the holders on the record date for the distribution payment.
If notice is given and funds are deposited as required, then on the redemption
date all rights of holders of the preferred trust securities called for
redemption will cease, except the right of the holders to receive the redemption
price plus accrued and unpaid distributions, and the preferred trust securities
will cease to be outstanding. No interest will accrue on amounts payable on the
redemption date. If any date fixed for redemption of preferred trust securities
is not a business day, then payment will be made on the next business day. No
interest will be payable because of any such delay. If payment of preferred


                                    -12-
<PAGE>


trust securities called for redemption is improperly withheld or refused and not
paid either by TXU Gas Capital or by TXU Gas Company in accordance with the
guarantee, distributions on those preferred trust securities will continue to
accrue to the date of payment. That date will be considered the date fixed for
redemption for purposes of calculating the redemption price plus accrued and
unpaid distributions (Trust Agreement, Section 4.02(d)).

      Subject to applicable law, including United States federal securities law,
TXU Gas Company may purchase outstanding preferred trust securities by tender,
in the open market or by private agreement.

      If preferred trust securities are partially redeemed on a redemption date,
a corresponding percentage of the common trust securities will be redeemed. The
particular preferred trust securities to be redeemed will be selected not more
than 60 days before the redemption date by the property trustee by a method that
the property trustee determines is fair, taking into account the denominations
in which they were issued. The property trustee will promptly notify the
registrar for the preferred trust security in writing of the preferred trust
securities selected for redemption and, where applicable, the partial amount to
be redeemed (Trust Agreement, Section 4.02(f)).

      SUBORDINATION OF COMMON TRUST SECURITIES

      Payment of distributions on, and the redemption price, plus accrued and
unpaid distributions, of, the preferred trust securities and common trust
securities will be made proportionately based on the liquidation preference
amount. However, if on any distribution payment date or redemption date an Event
of Default under the trust agreement has occurred and is continuing, no payment
on any common trust security will be made until all payments due on the
preferred trust securities have been made. In that case, funds available to the
property trustee will first be applied to the payment in full of all
distributions on, or the redemption price plus accrued and unpaid distributions
of, preferred trust securities then due and payable (Trust Agreement, Section
4.03(a)).

      If an Event of Default under the trust agreement results from an Event of
Default under the subordinated indenture, the holder of common trust securities
cannot take action with respect to the trust agreement default until the effect
of all defaults with respect to preferred trust securities has been cured,
waived or otherwise eliminated. Until the Event of Default under the trust
agreement with respect to preferred trust securities has been cured, waived or
otherwise eliminated, the property trustee will act solely on behalf of the
holders of preferred trust securities and not the holders of the common trust
securities. Only holders of preferred trust securities will have the right to
direct the property trustee to act on their behalf (Trust Agreement, Section
4.03(b)).

      LIQUIDATION DISTRIBUTION UPON DISSOLUTION

      TXU Gas Capital will be dissolved and will be liquidated by the property
trustee on the first to occur of:

      ( )  The expiration of the term of TXU Gas Capital;

      ( )  The bankruptcy, dissolution or liquidation of TXU Gas Company;

      ( )  Redemption of all of the preferred trust securities;

      ( )  The entry of an order for dissolution of TXU Gas Capital by a court
           of competent jurisdiction; and

      ( )  At any time, at the election of TXU Gas Company (Trust Agreement,
           Sections 9.01 and 9.02).

      If an early dissolution occurs because of bankruptcy, dissolution or
liquidation of TXU Gas Company, if all the preferred trust securities are
redeemed, or if TXU Gas Company so elects, TXU Gas Capital will be liquidated by
the property trustee as expeditiously as the property trustee determines to be
appropriate. The property trustee will provide for the satisfaction of
liabilities of creditors, if any, and distribute to each holder of the preferred


                                    -13-
<PAGE>


trust securities and common trust securities a proportionate amount of junior
subordinated debentures. If a distribution of junior subordinated debentures is
determined by the property trustee not to be practical, holders will be entitled
to receive, out of the assets of TXU Gas Capital after adequate provision for
the satisfaction of liabilities of creditors, if any, an amount equal to the
aggregate liquidation preference of the preferred trust securities plus accrued
and unpaid distributions on them to the date of payment. If this liquidation
distribution can be paid only in part because TXU Gas Capital has insufficient
assets available to pay in full the aggregate liquidation distribution, then the
amounts payable directly by TXU Gas Capital on the preferred trust securities
will be paid to the holders proportionately based on the total liquidation
preference amount of the preferred trust securities they hold. TXU Gas Company,
as holder of the common trust securities, will be entitled to receive
distributions upon any dissolution proportionately with the holders of the
preferred trust securities, except that if an Event of Default has occurred and
is continuing under the trust agreement, the preferred trust securities will
have a preference over the common trust securities (Trust Agreement, Section
9.04).

      EVENTS OF DEFAULT; NOTICE

      Any one of the following events will be an Event of Default under the
trust agreement whether it will be voluntary or involuntary or be effected by
operation of law or in accordance with any judgment, decree or order of any
court or any order, rule or regulation of any administrative or governmental
body:

      ( )  The occurrence of an Event of Default under the subordinated
           indenture;

      ( )  Default by TXU Gas Capital in the payment of any distribution when it
           becomes due and payable, and continuation of that default for 30
           days;

      ( )  Default by TXU Gas Capital in the payment of any redemption price,
           plus accrued and unpaid distributions, of any preferred trust
           security or common trust security when it becomes due and payable;

      ( )  Default in the performance, or breach, in any material respect, of
           any covenant or warranty of the trustees in the trust agreement which
           is not dealt with above, and the continuation of that default or
           breach for 60 days after notice to TXU Gas Capital by the holders of
           preferred trust securities having at least 10% of the total
           liquidation preference amount of the outstanding preferred trust
           securities; or

      ( )  The occurrence of specified events of bankruptcy or insolvency with
           respect to TXU Gas Capital (Trust Agreement, Section 1.01).

      Within 90 business days after the occurrence of any Event of Default under
the trust agreement, the property trustee will transmit to the holders of
preferred trust securities and common trust securities and TXU Gas Company
notice of any default actually known to the property trustee, unless that
default has been cured or waived (Trust Agreement, Section 8.01(a)).

      A holder of preferred trust securities may directly institute a proceeding
to enforce payment when due directly to the holder of the preferred trust
securities of the principal of or interest on junior subordinated debentures
having a principal amount equal to the aggregate liquidation preference amount
of the holder's preferred trust securities. The holders of preferred trust
securities have no other rights to exercise directly any other remedies
available to the holder of the junior subordinated debentures unless the
property trustee fails to do so (Trust Agreement, Section 6.01(a)).

      Unless an Event of Default under the subordinated indenture has occurred
and is continuing, the holder of the common trust securities may remove the
property trustee at any time. If an Event of Default under the subordinated
indenture has occurred and is continuing, the holders of a majority of the total
liquidation preference amount of the outstanding preferred trust securities may
remove the property trustee. Any resignation or removal of the property trustee


                                    -14-
<PAGE>


will take effect only on the acceptance of appointment by the successor
property trustee (Trust Agreement, Section 8.10).

      MERGER OR CONSOLIDATION OF THE PROPERTY TRUSTEE OR THE DELAWARE TRUSTEE

      If the property trustee or the Delaware trustee merge or consolidate with
another entity, or if any entity succeeds to all or substantially all the
corporate trust business of the property trustee or the Delaware trustee, the
successor or surviving company will be the successor to the property trustee or
the Delaware trustee under the trust agreement, so long as it is otherwise
qualified and eligible (Trust Agreement, Section 8.12).

      VOTING RIGHTS

      Except with respect to amendments to the trust agreement and amendments to
and assignment of the guarantee, the holders of preferred trust securities will
have no voting rights not otherwise required by law or the trust agreement
(Trust Agreement, Section 6.01(a)).

      While junior subordinated debentures are held by the property trustee, the
property trustee will not:

      ( )  Direct the time, method and place to conduct any proceeding for any
           remedy available to the debenture trustee, or to execute any trust or
           power conferred on the debenture trustee with respect to the junior
           subordinated debentures;

      ( )  Waive any past default under the subordinated indenture;

      ( )  Exercise any right to rescind or annul a declaration that the
           principal of all the junior subordinated debentures will be due and
           payable; or

      ( )  Consent to any amendment, modification or termination of the
           subordinated indenture or the junior subordinated debentures, where
           that consent will be required;

without, in each case, obtaining the prior approval of the holders of preferred
trust securities having at least 66 2/3% of the liquidation preference amount of
the outstanding preferred trust securities. Where a consent of each holder of
junior subordinated debentures affected is required, no consent will be given by
the property trustee without the prior consent of each holder of the preferred
trust securities. The property trustee will not revoke any action previously
authorized or approved by a vote of the holders of preferred trust securities.
If the property trustee fails to enforce its rights under the junior
subordinated debentures or the trust agreement, to the fullest extent permitted
by law, a holder of the preferred trust securities may institute a legal
proceeding directly against TXU Gas Company to enforce the property trustee's
rights under the junior subordinated debentures or the trust agreement without
first instituting any legal proceeding against the property trustee or anyone
else. The property trustee will notify all holders of preferred trust securities
of any notice of default received from the debenture trustee. The property
trustee will not take any action approved by the consent of the holders of the
preferred trust securities without an opinion of counsel experienced in those
matters to the effect that TXU Gas Capital will not be classified as an
association taxable as a corporation for United States federal income tax
purposes on account of that action (Trust Agreement, Sections 6.01(a) and
6.01(b)).

      Holders of preferred trust securities may give any required approval at a
meeting convened for that purpose or by written consent without prior notice
(Trust Agreement, Section 6.06). The administrative trustees will give notice of
any meeting at which holders of preferred trust securities are entitled to vote
(Trust Agreement, Section 6.02).

      No vote or consent of the holders of preferred trust securities will be
required for TXU Gas Capital to redeem and cancel preferred trust securities in
accordance with the trust agreement.


                                    -15-
<PAGE>


      Although holders of preferred trust securities are entitled to vote or
consent under any of the circumstances described above, any of preferred trust
securities that are owned by TXU Gas Company, any trustee under the trust
agreement or any affiliate of TXU Gas Company, will be treated as if they were
not outstanding for purposes of that vote or consent (Trust Agreement, Section
1.01).

      Unless an Event of Default under the subordinated indenture has occurred
and is continuing, holders of preferred trust securities will have no rights to
appoint or remove the administrative trustees of TXU Gas Capital, who may be
appointed, removed or replaced solely by TXU Gas Company as the holder of the
common trust securities (Trust Agreement, Section 8.10).

      AMENDMENTS

      The trust agreement may be amended from time to time by TXU Gas Capital
and TXU Gas Company without the consent of any holders of preferred trust
securities and common trust securities:

      ( )  To cure any ambiguity, correct inconsistent provisions, make any
           other provisions with respect to matters or questions arising under
           the trust agreement that do not conflict with the other provisions of
           the trust agreement or any amendments of the trust agreement, or to
           change the name of the trust; or

      ( )  To modify, eliminate or add to any provisions of the trust agreement
           to the extent necessary to ensure that TXU Gas Capital will not be
           classified as an association taxable as a corporation for United
           States federal income tax purposes at any time that any preferred
           trust securities and common trust securities are outstanding or to
           ensure TXU Gas Capital's exemption from the status of an "investment
           company" under the Investment Company Act of 1940.

No amendment described above may materially adversely affect the interests of
any holder of preferred trust securities and common trust securities. The
amendments to the trust agreement which cure ambiguity, correct inconsistencies
or supplement existing provisions will become effective when notice of the
amendment is given to the holders of preferred trust securities and common trust
securities (Trust Agreement, Section 10.03(a)).

      Except as provided below, any provision of the trust agreement may be
amended by the administrative trustees and TXU Gas Company with:

      ( )  The consent of holders of preferred trust securities and common trust
           securities representing not less than a majority of the total
           liquidation preference amount of the preferred trust securities and
           common trust securities then outstanding; and

      ( )  Receipt by the trustees of an opinion of counsel to the effect that
           the amendment or the exercise of any power granted to the trustees in
           accordance with the amendment will not cause TXU Gas Capital to be
           classified as an association taxable as a corporation for United
           States federal income tax purposes or affect TXU Gas Capital's
           exemption from status of an "investment company" under the Investment
           Company Act (Trust Agreement, Section 10.03(b)).

      Each holder of preferred trust securities or common trust securities must
consent to any amendment to the trust agreement that:

      ( )  Changes the amount or timing of any distribution with respect to
           preferred trust securities or common trust securities or otherwise
           adversely affects the amount of any distribution required to be made
           in respect of preferred trust securities and common trust securities
           as of a specified date; or

      ( )  Restricts the right of a holder of preferred trust securities and
           common trust securities to institute suit for the enforcement of any
           distribution on or after a specified date (Trust Agreement, Section
           10.03(c)).


                                    -16-
<PAGE>


      CO-TRUSTEES AND SEPARATE TRUSTEE

      If no Event of Default under the trust agreement has occurred and is
continuing, for the purpose of meeting the legal requirements of the Trust
Indenture Act or of any jurisdiction in which any part of the trust property of
TXU Gas Capital may at the time be located, TXU Gas Company and the property
trustee may appoint one or more persons approved by the property trustee either
to act as co-trustee, jointly with the property trustee, of all or any part of
the trust property, or to act as separate trustee of any trust property. Upon
the written request of the property trustee, TXU Gas Company will for that
purpose join with the property trustee in the execution, delivery and
performance of all instruments necessary or proper to make that appointment. The
appointment will vest in that person or persons in that capacity, any property,
title, right or power deemed necessary or desirable, subject to the provisions
of the trust agreement. If TXU Gas Company does not join in that appointment
within 15 days after the receipt by it of a request so to do, or in case an
Event of Default under the subordinated indenture has occurred and is
continuing, the property trustee alone will have power to make that appointment
(Trust Agreement, Section 8.09).

      FORM, EXCHANGE, AND TRANSFER

      Preferred trust securities of any TXU Gas Capital Trust may be exchanged
for other preferred trust securities of that trust in any authorized
denomination and with the same terms and total liquidation preference (Trust
Agreement, Section 5.04).

      Subject to the terms of the trust agreement, preferred trust securities
may be presented for exchange as provided above or for registration of transfer,
duly endorsed or accompanied by a duly executed instrument of transfer, at the
office of the preferred trust security registrar or at the office of any
transfer agent designated by TXU Gas Company for that purpose. TXU Gas Company
may designate itself the preferred trust security registrar. No service charge
will be made for any registration of transfer or exchange of preferred trust
securities, but TXU Gas Company may require payment of a sum sufficient to cover
any tax or other governmental charge payable in connection with the transfer. In
that case, the holder requesting transfer must pay the tax or charges and give
any indemnity that TXU Gas Capital or TXU Gas Company may require (Trust
Agreement, Section 5.04). A transfer or exchange will be made when the transfer
agent is satisfied with the documents of title and identity of the person making
the request. TXU Gas Company may at any time designate additional transfer
agents or rescind the designation of any transfer agent or approve a change in
the office through which any transfer agent acts, except that TXU Gas Company
will be required to maintain a transfer agent in each place of payment for
preferred trust securities.

      TXU Gas Capital will not be required to:

      ( )  Issue, register the transfer of, or exchange any preferred trust
           securities during the 15 calendar days before the mailing of a notice
           of redemption of any preferred trust securities called for redemption
           and ending at the close of business on the day the notice is mailed;
           or

      ( )  Register the transfer of or exchange any preferred trust securities
           so selected for redemption, in whole or in part, except the
           unredeemed portion of any preferred trust securities being redeemed
           in part (Trust Agreement, Section 5.04).

      REGISTRAR AND TRANSFER AGENT

      TXU Business Services Company, an affiliate of TXU Gas Company, will act
as registrar and transfer agent for the preferred trust securities (Trust
Agreement, Section 5.04).


                                    -17-
<PAGE>


      CONCERNING THE PROPERTY TRUSTEE

      The property trustee will be The Bank of New York, which also acts as
trustee under various indentures and trusts of TXU Gas Company, TXU Corp and
other affiliates, including the indentures for the debt securities described
above, and the junior subordinated debentures described below. TXU Gas Company,
TXU Corp and other affiliates maintain deposit accounts and credit and liquidity
facilities and conduct other banking transactions with the property trustee in
the ordinary course of their businesses. The property trustee also acts as the
guarantee trustee under the guarantee and the debenture trustee under the
subordinated indenture. The Delaware trustee will be The Bank of New York
(Delaware).

      DUTIES OF THE TRUSTEES

      The Delaware trustee will act as the resident trustee in the State of
Delaware and will have no other significant duties (Trust Agreement, Section
2.06). The property trustee will hold the junior subordinated debentures on
behalf of TXU Gas Capital and will maintain a payment account with respect to
the preferred trust securities and common trust securities, and will also act as
trustee under the trust agreement for the purposes of the Trust Indenture Act.

      The administrative trustees of TXU Gas Capital are authorized and directed
to conduct the affairs of TXU Gas Capital and to operate TXU Gas Capital so that
TXU Gas Capital will not be deemed to be an "investment company" required to be
registered under the Investment Company Act or taxed as a corporation for United
States federal income tax purposes and so that the junior subordinated
debentures will be treated as indebtedness of TXU Gas Company for United States
federal income tax purposes. In this regard, the administrative trustees are
authorized to take any action, not inconsistent with applicable law, the
certificate of trust or the trust agreement, that the administrative trustees
determine in their discretion to be necessary or desirable for those purposes,
as long as the action does not materially adversely affect the interests of the
holders of the preferred trust securities (Trust Agreement, Section 2.07(d)).

      GOVERNING LAW

      The trust agreement and the preferred trust securities will be governed
by, and construed in accordance with, the laws of the State of Delaware (Trust
Agreement, Section 10.05).

      MISCELLANEOUS

      Holders of the preferred trust securities have no preemptive or similar
rights (Trust Agreement, Section 5.13).


                          DESCRIPTION OF THE GUARANTEE

      Material terms of the guarantee that TXU Gas Company will execute and
deliver for the benefit of the holders of the preferred trust securities are
summarized below.  The form of guarantee was filed with the SEC and you should
read the guarantee for provisions that may be important to you. The guarantee
will be qualified as an indenture under the Trust Indenture Act. You should
refer to the Trust Indenture Act for provisions that apply to the guarantee.
Whenever particular provisions or defined terms of the guarantee are referred
to in this prospectus, those provisions or defined terms are incorporated in
this prospectus by reference.

      The Bank of New York will act as guarantee trustee under the guarantee.
The Bank of New York also will act as the property trustee under the trust
agreement and the debenture trustee under the subordinated indenture. The
guarantee trustee will hold the guarantee for the benefit of the holders of the
preferred trust securities.


                                    -18-
<PAGE>


      GENERAL TERMS OF THE GUARANTEE

      TXU Gas Company will irrevocably and unconditionally agree to make the
guarantee payments listed below in full to the holders of the preferred trust
securities if they are not made by TXU Gas Capital, as and when due, regardless
of any defense, right of set-off or counterclaim that TXU Gas Company may have
or assert. The following payments will be subject to the guarantee, without
duplication:

      ( )  Any accrued and unpaid distributions required to be paid on preferred
           trust securities, to the extent TXU Gas Capital has sufficient funds
           available for payments;

      ( )  The redemption price, plus all accrued and unpaid distributions, for
           any preferred trust securities called for redemption by TXU Gas
           Capital, to the extent TXU Gas Capital has sufficient funds available
           for payments; and

      ( )  Upon a voluntary or involuntary dissolution, winding-up or
           termination of TXU Gas Capital except in connection with (1) the
           distribution of junior subordinated debentures to the holders in
           exchange for preferred trust securities as provided in the trust
           agreement or (2) the redemption of all of the preferred trust
           securities upon maturity or redemption of the junior subordinated
           debentures as provided in the trust agreement, the lesser of:

           (1)     the total liquidation preference amount of, and all accrued
                   and unpaid distributions on, preferred
                   trust securities to the date of payment; and

           (2)     the amount of assets of TXU Gas Capital remaining
                   available for distribution to holders of preferred
                   trust securities in liquidation of TXU Gas Capital
                   (Guarantee Agreement, Section 5.01).

TXU Gas Company's obligation to make a guarantee payment may be satisfied by
direct payment of the required amounts by TXU Gas Company to the holders of
preferred trust securities or by causing TXU Gas Capital to pay those amounts to
the holders (Guarantee Agreement, Section 5.01).

      The guarantee will be a guarantee with respect to the preferred trust
securities, but will not apply to any payment of distributions if and to the
extent that TXU Gas Capital lacks the funds available to make those payments or
to any collection of payment.

      If TXU Gas Company does not make interest payments on the junior
subordinated debentures held by TXU Gas Capital, TXU Gas Capital will not have
funds available to pay distributions on the preferred trust securities. The
guarantee will rank subordinate and junior in right of payment to all
liabilities of TXU Gas Company except liabilities that are equal in right of
payment by their terms (Guarantee Agreement, Section 6.01).

      TXU Gas Company will enter into an agreement as to expenses and
liabilities with TXU Gas Capital, to provide funds to TXU Gas Capital as needed
to pay obligations of TXU Gas Capital to parties other than holders of preferred
trust securities. The junior subordinated debentures and the guarantee, together
with the obligations of TXU Gas Company with respect to the preferred trust
securities under the subordinated indenture, the trust agreement, the guarantee
and the agreement as to expenses and liabilities, constitute a full and
unconditional guarantee of the preferred trust securities by TXU Gas Company. No
single document standing alone or operating in conjunction with fewer than all
of the other documents constitutes that guarantee. It is only the combined
operation of these documents that has the effect of providing a full and
unconditional guarantee by TXU Gas Company of the preferred trust securities.


                                    -19-
<PAGE>


      AMENDMENTS AND ASSIGNMENT

      No vote is required for changes to the trust agreement that do not
materially adversely affect the rights of holders of preferred trust securities.
Other terms of the guarantee may be changed only with the prior approval of the
holders of the preferred trust securities having at least 66 2/3% of the total
liquidation preference amount of the outstanding preferred trust securities
(Guarantee Agreement, Section 8.02). All guarantees and agreements contained in
the guarantee will bind the successors, assigns, receivers, trustees and
representatives of TXU Gas Company and will inure to the benefit of the holders
of the preferred trust securities then outstanding (Guarantee Agreement, Section
8.01).

      EVENTS OF DEFAULT

      An Event of Default under the guarantee will occur if TXU Gas Company
fails to perform any of its payment obligations under the guarantee (Guarantee
Agreement, Section 1.01). The holders of the preferred trust securities having a
majority of the total liquidation preference amount of the preferred trust
securities have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the guarantee trustee under the guarantee
or to direct the exercise of any trust or power conferred upon the guarantee
trustee under the guarantee (Guarantee Agreement, Section 5.04).

      If the guarantee trustee fails to enforce the guarantee, any holder of the
preferred trust securities may enforce the guarantee, or institute a legal
proceeding directly against TXU Gas Company to enforce the guarantee trustee's
rights under the guarantee without first instituting a legal proceeding against
TXU Gas Capital, the guarantee trustee or anyone else (Guarantee Agreement,
Section 5.04).

      TXU Gas Company will be required to provide an annual statement to the
guarantee trustee about TXU Gas Company's performance of some of its obligations
under the guarantee and any default in its performance of the obligations.

      TXU Gas Company will also be required to file annually with the guarantee
trustee an officer's certificate as to TXU Gas Company's compliance with all
conditions under the guarantee (Guarantee Agreement, Section 2.04).

      INFORMATION CONCERNING THE GUARANTEE TRUSTEE

      The guarantee trustee will undertake to perform only those duties
specifically described in the guarantee until a default occurs. After a default
under the guarantee, the guarantee trustee must exercise the same degree of care
in its duties as a prudent individual would exercise in the conduct of his or
her own affairs (Guarantee Agreement, Section 3.01(b)). Otherwise, the guarantee
trustee is under no obligation to exercise any of the powers vested in it by the
guarantee at the request of any holder of the preferred trust securities unless
it is offered reasonable indemnity against the costs, expenses and liabilities
that it might incur (Guarantee Agreement, Section 3.01(c)).

      TERMINATION OF THE GUARANTEE

      The guarantee will terminate and be of no further force and effect upon:

      ( )  Full payment of the redemption price, plus accrued and unpaid
           distributions, for all the preferred trust securities;

      ( )  The distribution of junior subordinated debentures to holders of the
           preferred trust securities in exchange for all of the preferred trust
           securities; or

      ( )  Full payment of the amounts payable upon liquidation of TXU Gas
           Capital.

                                    -20-
<PAGE>


      The guarantee will continue to be effective or will be reinstated, as the
case may be, if at any time any holder of preferred trust securities must
restore payment of any sums paid under the preferred trust securities or the
guarantee (Guarantee Agreement, Section 7.01).

      STATUS OF THE GUARANTEE

      The guarantee will be an unsecured obligation of TXU Gas Company and will
rank:

      ( )  Subordinate and junior in right of payment to all liabilities of TXU
           Gas Company, except any liabilities that are equal in right of
           payment by their terms;

      ( )  Equal in right of payment with the most senior preferred or
           preference stock that may be issued by TXU Gas Company and with any
           guarantee that may be entered into by TXU Gas Company in respect of
           any preferred or preference stock of any affiliate of TXU Gas
           Company; and

      ( )  Senior to TXU Gas Company's common stock (Guarantee Agreement,
           Section 6.01).

      The trust agreement provides that by accepting preferred trust securities,
a holder agrees to the subordination provisions and other terms of the
guarantee.

      The guarantee will be a guarantee of payment and not of collection
(Guarantee Agreement, Section 5.05). That is, the guaranteed party may institute
a legal proceeding directly against TXU Gas Company to enforce its rights under
the guarantee without first instituting a legal proceeding against anyone else.

      GOVERNING LAW

      The guarantee will be governed by, and construed in accordance, with the
laws of the State of New York (Guarantee Agreement, Section 8.06).


                DESCRIPTION OF THE JUNIOR SUBORDINATED DEBENTURES

      The junior subordinated debentures which the property trustee will hold on
behalf of TXU Gas Capital as trust assets will be subordinated obligations of
TXU Gas Company. The junior subordinated debentures will be issued under the
subordinated indenture.

      Material terms of the junior subordinated debentures and the subordinated
indenture are summarized below. The subordinated indenture has been filed with
the SEC, and you should read the subordinated indenture for provisions that may
be important to you. The subordinated indenture will be qualified under the
Trust Indenture Act. You should refer to the Trust Indenture Act for provisions
that apply to the junior subordinated debentures. Whenever particular provisions
or defined terms in a subordinated indenture are referred to in this prospectus,
those provisions or defined terms are incorporated by reference in this
prospectus.

      The subordinated indenture provides for the issuance of subordinated
debentures, including the junior subordinated debentures, and other subordinated
debt in an unlimited amount from time to time (Subordinated Indenture, Section
301). The junior subordinated debentures issued to TXU Gas Capital will
constitute a separate series of subordinated debentures under the subordinated
indenture.

                                    -21-
<PAGE>


      A prospectus supplement and an officer's certificate relating to the
junior subordinated debentures being offered will include specific terms
relating to that offering. These terms will include some or all of the
following:

      ( )  The title of the junior subordinated debentures;

      ( )  The total principal amount of the junior subordinated debentures;

      ( )  The dates on which the principal of the junior subordinated
           debentures will be payable and how it will be paid;

      ( )  The interest rate or rates which the junior subordinated debentures
           will bear, or how the rate or rates will be determined, the interest
           payment dates for the junior subordinated debentures and the regular
           record dates for interest payments;

      ( )  Any right to extend the interest payment periods for the junior
           subordinated debentures;

      ( )  The percentage, if less than 100%, of the principal amount of the
           junior subordinated debentures that will be payable if the maturity
           of the junior subordinated debentures is accelerated;

      ( )  Any date or dates on which the junior subordinated debentures may be
           redeemed at the option of TXU Gas Company and any restrictions on
           those redemptions;

      ( )  Any sinking fund or other provisions that would obligate TXU Gas
           Company to repurchase or otherwise redeem the junior subordinated
           debentures;

      ( )  Any changes or additions to the Events of Default under the
           subordinated indenture or changes or additions to the covenants of
           TXU Gas Company under the subordinated indenture;

      ( )  If the junior subordinated debentures will be issued in denomination
           other than $25;

      ( )  If payments on the junior subordinated debentures may be made in a
           currency or currencies other than United States dollars; and

      ( )  Any other terms of the junior subordinated debentures not
           inconsistent with the terms of the subordinated indenture
           (Subordinated Indenture, Section 301).

      The junior subordinated debentures of each series will be limited in total
principal amount to the sum of the total liquidation preference amount of the
preferred trust securities and the consideration paid by TXU Gas Company for the
common trust securities of the related TXU Gas Capital trust. The junior
subordinated debentures are unsecured, subordinated obligations of TXU Gas
Company which rank junior to all of TXU Gas Company's Senior Indebtedness
(Subordinated Indenture, Section 1501). Senior Indebtedness is defined in the
subordinated indenture to include all notes and other obligations including
guarantees of TXU Gas Company for borrowed money that is not subordinate or
junior in right of payment to any other indebtedness of TXU Gas Company unless
by its terms it is equal in right of payment to the junior subordinated
debentures. The obligations of TXU Gas Company under the guarantee and the
junior subordinated debentures will not be deemed to be Senior Indebtedness
(Subordinated Indenture, Section 101). The amounts payable as principal and
interest on the junior subordinated debentures will be sufficient to provide for
payment of distributions payable on preferred trust securities and common trust
securities.

      If junior subordinated debentures are distributed to holders of preferred
trust securities in a dissolution of TXU Gas Capital, the junior subordinated
debentures will be issued in fully registered certificated form in the
denominations and integral multiples of the denominations in which the preferred


                                    -22-
<PAGE>


trust securities have been issued, and they may be transferred or exchanged at
the offices of the debenture trustee (Subordinated Indenture, Section 201).

      Payments of principal and interest on junior subordinated debentures will
be payable, the transfer of junior subordinated debentures will be registrable,
and junior subordinated debentures will be exchangeable for junior subordinated
debentures of the same series of other denominations of the same total principal
amount, at the corporate trust office of the debenture trustee in The City of
New York (Subordinated Indenture, Section 602). However, TXU Gas Company may
choose to make payment of interest by check mailed to the address of the persons
entitled to it and may require that the payment in full of principal with
respect to any junior subordinated debenture be made only upon surrender of the
junior subordinated debenture to the debenture trustee.

      OPTIONAL REDEMPTION

      For so long as TXU Gas Capital is the holder of all the related
outstanding junior subordinated debentures, the proceeds of any optional
redemption will be used by TXU Gas Capital to redeem preferred trust securities
and common trust securities in accordance with their terms.

      The debenture trustee will give notice to the holders of any optional
redemption of junior subordinated debentures, not less than 30 nor more than 60
days before that redemption. All notices of redemption will state the redemption
date and the redemption price plus accrued and unpaid interest. If less than all
the junior subordinated debentures are to be redeemed, the notice will identify
those to be redeemed and the portion of the principal amount of any junior
subordinated debentures to be redeemed in part. The notice will state that on
the redemption date, subject to the debenture trustee's receipt of the
redemption monies, the redemption price plus accrued and unpaid interest will
become due and payable on each junior subordinated debenture to be redeemed and
that interest will cease to accrue on and after that date. It will name the
place or places where the junior subordinated debentures are to be surrendered
for payment of the redemption price plus accrued and unpaid interest
(Subordinated Indenture, Section 404).

      INTEREST

      The amount of interest payable for any period will be computed on the
basis of a 360-day year of twelve 30-day months and for any period shorter than
a full month, on the basis of the actual number of days elapsed (Subordinated
Indenture, Section 310). If any date on which interest is payable on the junior
subordinated debentures is not a business day, then payment will be made on the
next business day. No interest will be paid in respect of any such delay.
However, if the delayed payment date is in the next calendar year, the payment
will be made on the last business day of the earlier year. These payments will
have the same force and effect as if made on the date the payment was originally
payable (Subordinated Indenture, Section 113).

      OPTION TO EXTEND INTEREST PAYMENT PERIOD

      So long as there is no default in the payment of interest on the junior
subordinated debentures, TXU Gas Company may extend the interest payment period
from time to time on the junior subordinated debentures for one or more periods
(Subordinated Indenture, Section 311). As a consequence, distributions on
preferred trust securities would be deferred during any extension period.
Interest would, however, continue to accrue. If TXU Gas Company extends the
interest period or is in default under the guarantee or with respect to payments
on the junior subordinated debentures, TXU Gas Company may not:

      ( )  Declare or pay any dividend or distribution on its capital stock,
           other than dividends paid in shares of common stock of TXU Gas
           Company;

      ( )  Redeem, purchase, acquire or make a liquidation payment with
           respect to any of its capital stock;


                                    -23-
<PAGE>


      ( )  Redeem any indebtedness that is equal in right of payment with the
           junior subordinated debentures; or

      ( )  Make any guarantee payments with respect to any of the above
          (Subordinated Indenture, Section 608).

      Any extension period with respect to payment of interest on the junior
subordinated debentures, or any extension period in respect of other securities
issued under the subordinated indenture or on any similar securities, will apply
to all securities of the same type. Those extensions will also apply to
distributions on preferred trust securities and common trust securities and all
other securities with terms substantially the same as preferred trust securities
and common trust securities. Before an extension period ends, TXU Gas Company
may further extend the interest payment period. No extension period as further
extended may exceed 20 consecutive quarters. After any extension period and the
payment of all amounts then due, TXU Gas Company may select a new extension
period. No interest period may be extended beyond the maturity of the junior
subordinated debentures. TXU Gas Company will give TXU Gas Capital and the
debenture trustee notice of its election of an extension period before the
earlier of (1) one business day before the record date for the distribution
which would occur if TXU Gas Company did not make the election to extend or (2)
the date TXU Gas Company is required to give notice to the New York Stock
Exchange or any other applicable self-regulatory organization of the record
date. TXU Gas Company will cause TXU Gas Capital to send notice of that election
to the holders of preferred trust securities.

      ADDITIONAL INTEREST

      So long as any preferred trust securities remain outstanding, if TXU Gas
Capital is required to pay any taxes, duties, assessments or governmental
charges imposed by the United States or any other taxing authority on income
derived from the interest payments on the junior subordinated debentures, then
TXU Gas Company will pay as interest on the junior subordinated debentures any
additional interest that may be necessary in order that the net amounts retained
by TXU Gas Capital after the payment of those taxes, duties, assessments or
governmental charges will be the same as TXU Gas Capital would have had in the
absence of the payment of those taxes, duties, assessments or governmental
charges (Subordinated Indenture, Section 312).

      DEFEASANCE

      TXU Gas Company will be discharged from its obligations on the
subordinated debentures of a particular series if it deposits with the debenture
trustee sufficient cash or government securities to pay the principal, interest,
any premium and any other sums when due on the stated maturity date or a
redemption date of that series of the subordinated debentures (Subordinated
Indenture, Section 701).

      SUBORDINATION

      The junior subordinated debentures will be subordinate and junior in right
of payment to all Senior Indebtedness of TXU Gas Company (Subordinated
Indenture, Section 1501). No payment of the principal of the junior subordinated
debentures, including redemption and sinking fund payments, or interest on the
junior subordinated debentures may be made until all holders of Senior
Indebtedness have been paid, if any of the following occurs:

      ( )  Specified events of bankruptcy, insolvency or reorganization of TXU
           Gas Company;

      ( )  Any Senior Indebtedness is not paid when due and that default
           continues without waiver;

      ( )  Any other default has occurred and continues without waiver,
           permitting the holders of Senior Indebtedness to accelerate the
           maturity of that indebtedness; or


                                    -24-
<PAGE>


      ( )  The maturity of any other series of subordinated debentures under the
           subordinated indenture has been accelerated, because of an Event of
           Default under the subordinated indenture which remains uncured
           (Subordinated Indenture, Section 1502).

      Upon any distribution of assets of TXU Gas Company to creditors in
connection with any insolvency, bankruptcy or similar proceeding, all principal
of, and premium, if any, and interest due or to become due on all Senior
Indebtedness must be paid in full before the holders of the junior subordinated
debentures are entitled to receive or retain any payment (Subordinated
Indenture, Section 1504).

      The subordinated indenture does not limit the aggregate amount of Senior
Indebtedness that may be issued. As of June 30, 1999 TXU Gas Company had
approximately $701 million principal amount of indebtedness for borrowed money
constituting Senior Indebtedness.

      CONSOLIDATION, MERGER, AND SALE OF ASSETS

      Under the terms of the subordinated indenture, TXU Gas Company may not
consolidate with or merge into any other entity or convey, transfer or lease its
properties and assets substantially as an entirety to any entity, unless:

      ( )  The surviving or successor entity is organized and validly existing
           under the laws of any domestic jurisdiction and it expressly assumes
           TXU Gas Company's obligations on all subordinated debentures issued
           under the subordinated indenture;

      ( )  Immediately after giving effect to the transaction, no Event of
           Default under the subordinated indenture or no event which, after
           notice or lapse of time or both, would become an Event of Default
           under the subordinated indenture, occurs and is continuing; and

      ( )  TXU Gas Company delivers to the debenture trustee an officer's
           certificate and an opinion of counsel as provided in the subordinated
           indenture (Subordinated Indenture, Section 1101).

      EVENTS OF DEFAULT

      "Event of Default", when used in the subordinated indenture for
subordinated debentures of a specific series, will mean any of the following:

      ( )  Failure to pay interest on any subordinated debenture of that series
           for 30 days after it is due;

      ( )  Failure to pay the principal of or any premium on any subordinated
           debenture of that series when due;

      ( )  Failure to perform any other covenant in the subordinated indenture,
           other than a covenant that does not relate to subordinated debentures
           of that series, that continues for 90 days after TXU Gas Company
           receives written notice from the debenture trustee or TXU Gas Company
           and the debenture trustee receive a written notice from 33% of the
           holders of the subordinated debentures of that series;

      ( )  Specified events in bankruptcy, insolvency or reorganization of TXU
           Gas Company; or

      ( )  Any other Event of Default included in any supplemental indenture or
           officer's certificate for that series of subordinated debentures
           (Subordinated Indenture, Section 801).

      An Event of Default under the subordinated indenture for a particular
series of subordinated debentures does not necessarily constitute an Event of
Default under the subordinated indenture for any other series of subordinated
debentures issued under the subordinated indenture. The debenture trustee may


                                    -25-
<PAGE>


withhold notice to the holders of subordinated debentures of any default
except a default in the payment of principal or interest if it considers
the withholding of notice to be in the best interests of the holders.

      REMEDIES

      If an Event of Default under the subordinated indenture for any series of
subordinated debentures occurs and continues, the debenture trustee or the
holders of at least 33% in aggregate principal amount of the subordinated
debentures of the series may declare the entire principal amount of all the
subordinated debentures of that series, together with accrued interest, to be
due and payable immediately. However, if the Event of Default under the
subordinated indenture is applicable to all outstanding subordinated debentures
under the subordinated indenture, only the debenture trustee or holders of at
least 33% in aggregate principal amount of all outstanding subordinated
debentures of all series, voting as one class, and not the holders of any one
series, may make that declaration of acceleration (Subordinated Indenture,
Section 802).

      At any time after a declaration of acceleration with respect to the
subordinated debentures of any series has been made and before a judgment or
decree for payment of the money due has been obtained, the Event of Default
under the subordinated indenture giving rise to the declaration of acceleration
will be considered waived, and the declaration and its consequences will be
considered rescinded and annulled, if:

  ( )   TXU Gas Company has paid or deposited with the debenture trustee a sum
        sufficient to pay:

       (1)  all overdue interest on all subordinated debentures of the series;

       (2)  the principal of and premium, if any, on any subordinated debentures
            of the series which have otherwise become due and interest that is
            currently due;

       (3)  interest on overdue interest; and

       (4)  all amounts due to the debenture trustee under the subordinated
            indenture; and

  ( )   Any other Event of Default under the subordinated indenture with
        respect to the subordinated debentures of that series has been cured
        or waived as provided in the subordinated indenture (Subordinated
        Indenture, Section 802).

      There is no automatic acceleration, even in the event of bankruptcy,
insolvency or reorganization of TXU Gas Company.

      Other than its duties in case of an Event of Default under the
subordinated indenture, the debenture trustee is not obligated to exercise any
of its rights or powers under the subordinated indenture at the request, order
or direction of any of the holders, unless the holders offer the debenture
trustee a reasonable indemnity. If they provide this reasonable indemnity, the
holders of a majority in principal amount of any series of subordinated
debentures will have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the debenture trustee or
exercising any power conferred upon the debenture trustee. However, if the Event
of Default under the subordinated indenture relates to more than one series,
only the holders of a majority in aggregate principal amount of all affected
series will have the right to give this direction. The debenture trustee is not
obligated to comply with directions that conflict with law or other provisions
of the subordinated indenture (Subordinated Indenture, Section 812).


                                    -26-
<PAGE>


      No holder of subordinated debentures of any series will have any right to
institute any proceeding under the subordinated indenture, or any remedy under
the subordinated indenture, unless:

      ( )  The holder has previously given to the debenture trustee written
           notice of a continuing Event of Default under the subordinated
           indenture;

      ( )  The holders of a majority in aggregate principal amount of the
           outstanding subordinated debentures of all series in respect of which
           an Event of Default under the subordinated indenture will have
           occurred and be continuing have made a written request to the
           debenture trustee, and have offered reasonable indemnity to the
           debenture trustee to institute proceedings; and

      ( )  The debenture trustee has failed to institute any proceeding for 60
           days after notice (Subordinated Indenture, Section 807).

However, these limitations do not apply to a suit by a holder of a subordinated
debenture for payment of the principal, premium or interest on a subordinated
debenture on or after the applicable due date (Subordinated Indenture, Section
808).

      TXU Gas Company will provide to the debenture trustee an annual statement
by an appropriate officer as to TXU Gas Company's compliance with all conditions
and covenants under the subordinated indenture (Subordinated Indenture, Section
606).

      ENFORCEMENT OF RIGHTS BY HOLDERS OF PREFERRED TRUST SECURITIES

      If there is an Event of Default under the subordinated indenture, then the
holders of preferred trust securities will rely on the property trustee or the
debenture trustee, acting for the benefit of the property trustee, to enforce
the property trustee's rights against TXU Gas Company as a holder of the junior
subordinated debentures. However, a holder of preferred trust securities may
enforce the subordinated indenture directly against TXU Gas Company to the same
extent as if the holder of preferred trust securities held a principal amount of
junior subordinated debentures equal to the aggregate liquidation preference
amount of its preferred trust securities (Subordinated Indenture, Section 610).

      The holders of preferred trust securities would not be able to exercise
directly against TXU Gas Company any other rights unless the property trustee or
the debenture trustee failed to do so for 60 days. Upon that failure, the
holders of a majority of the aggregate liquidation preference amount of the
outstanding preferred trust securities would have the right to directly
institute proceedings for enforcement of all other rights against TXU Gas
Company to the fullest extent permitted by law (Subordinated Indenture, Section
807).

      MODIFICATION AND WAIVER

      Without the consent of any holder of subordinated debentures, TXU Gas
Company and the debenture trustee may enter into one or more supplemental
indentures for any of the following purposes:

      ( )  To evidence the assumption by any permitted successor of the
           covenants of TXU Gas Company in the subordinated indenture and in the
           subordinated debentures;

      ( )  To add additional covenants of TXU Gas Company or to surrender any
           right or power of TXU Gas Company under the subordinated indenture;

      ( )  To add additional Events of Default under the subordinated indenture;


                                    -27-
<PAGE>


      ( )  To change or eliminate or add any provision to the subordinated
           indenture; provided, however, if the change will adversely affect the
           interests of the holders of subordinated debentures of any series in
           any material respect, the change, elimination or addition will become
           effective only:

           (1)  when the consent of the holders of subordinated debentures of
                that series has been obtained in accordance with the
                subordinated indenture; or

           (2)  when no subordinated debentures of the affected series remain
                outstanding under the subordinated indenture;

      ( )  To provide collateral security for all but not part of the
           subordinated debentures;

      ( )  To establish the form or terms of subordinated debentures of any
           other series as permitted by the subordinated indenture;

      ( )  To provide for the authentication and delivery of bearer securities
           with or without coupons;

      ( )  To evidence and provide for the acceptance of appointment of a
           successor trustee;

      ( )  To provide for the procedures required for use of a noncertificated
           system of registration for the subordinated debentures of all or any
           series;

      ( )  To change any place where principal, premium and interest will be
           payable, subordinated debentures may be surrendered for registration
           of transfer or exchange and notices to TXU Gas Company may be served;
           or

      ( )  To cure any ambiguity or inconsistency or to make any other
           provisions with respect to matters and questions arising under the
           subordinated indenture; provided that the action will not adversely
           affect the interests of the holders of subordinated debentures of any
           series in any material respect (Subordinated Indenture, Section
           1201).

      The holders of at least a majority in aggregate principal amount of the
subordinated debentures of all series then outstanding may waive compliance by
TXU Gas Company with some restrictive provisions of the subordinated indenture
(Subordinated Indenture, Section 607). The holders of not less than a majority
in principal amount of the outstanding subordinated debentures of any series may
waive any past default under the subordinated indenture with respect to that
series, except a default in the payment of principal, premium, if any, or
interest and some covenants and provisions of the subordinated indenture that
cannot be modified or be amended without the consent of the holder of each
outstanding subordinated debenture of the series affected (Subordinated
Indenture, Section 813).

      If the Trust Indenture Act is amended after the date of the subordinated
indenture in a way as to require changes to the subordinated indenture, the
subordinated indenture will be deemed to be amended so as to conform to that
amendment of the Trust Indenture Act. TXU Gas Company and the debenture trustee
may, without the consent of any holders, enter into one or more supplemental
indentures to evidence the amendment (Subordinated Indenture, Section 1201).

      The consent of the holders of a majority in aggregate principal amount of
the subordinated debentures of all series then outstanding is required for all
other modifications to the subordinated indenture. However, if less than all of
the series of subordinated debentures outstanding are directly affected by a


                                    -28-
<PAGE>


proposed supplemental indenture, then the consent only of the holders of a
majority in aggregate principal amount of all series that are directly
affected will be required. No amendment or modification may:

      ( )  Change the stated maturity of the principal of, or any installment of
           principal of or interest on any subordinated debenture, or reduce the
           principal amount of any subordinated debenture or its rate of
           interest or change the method of calculating the interest rate or
           reduce any premium payable upon redemption, or change the currency in
           which payments are made, or impair the right to institute suit for
           the enforcement of any payment on or after the stated maturity of any
           subordinated debenture, without the consent of the holder;

      ( )  Reduce the percentage in principal amount of the outstanding
           subordinated debentures of any series whose consent is required for
           any supplemental indenture, or any waiver of compliance with a
           provision of the subordinated indenture or any default thereunder and
           its consequences, or reduce the requirements for quorum or voting,
           without the consent of all the holders of the series; or

      ( )  Modify some of the provisions of the subordinated indenture relating
           to supplemental indentures, waivers of some covenants and waivers of
           past defaults with respect to the subordinated debentures of any
           series, without the consent of the holder of each outstanding
           subordinated debenture affected by them (Subordinated Indenture,
           Section 1202).

      A supplemental indenture which changes the subordinated indenture solely
for the benefit of one or more particular series of subordinated debentures, or
modifies the rights of the holders of subordinated debentures of one or more
series, will not affect the rights under the subordinated indenture of the
holders of the subordinated debentures of any other series. So long as any of
preferred trust securities remain outstanding, the debenture trustee may not
consent to a supplemental indenture without the prior consent of the holders of
a majority in aggregate liquidation of all preferred trust securities or, in the
case of changes described in the clauses immediately above, 100% in aggregate
liquidation preference of all preferred trust securities then outstanding which
would be affected (Subordinated Indenture, Section 1202).

      The subordinated indenture provides that subordinated debentures owned by
TXU Gas Company or anyone else required to make payments on the subordinated
debentures will be disregarded and considered not to be outstanding in
determining whether the required holders have given a request or consent
(Subordinated Indenture, Section 101).

      TXU Gas Company may fix in advance a record date to determine the required
number of holders entitled to give any request, demand, authorization,
direction, notice, consent, waiver or other act of holders, but TXU Gas Company
will have no obligation to do so. If TXU Gas Company fixes a record date, the
request, demand, authorization, direction, notice, consent, waiver or other act
of the holders may be given before or after that record date, but only the
holders of record at the close of business on the record date will be considered
to be holders for the purposes of determining whether holders of the required
percentage of the outstanding subordinated debentures have authorized or agreed
or consented to the request, demand, authorization, direction, notice, consent,
waiver or other act of the holders. For that purpose the outstanding
subordinated debentures will be computed as of the record date. Any request,
demand, authorization, direction, notice, consent, election, waiver or other act
of a holder will bind every future holder of the same subordinated debenture and
the holder of every subordinated debenture issued upon the registration of
transfer of or exchange of subordinated debentures. A transferee will be bound
by acts of the debenture trustee or TXU Gas Company in reliance on those acts
whether or not notation of that action is made upon the subordinated debenture
(Subordinated Indenture, Section 104).

      RESIGNATION OF DEBENTURE TRUSTEE

      The debenture trustee may resign at any time by giving written notice to
TXU Gas Company or may be removed at any time by act of the holders of a
majority in principal amount of all series of subordinated debentures


                                    -29-
<PAGE>


then outstanding delivered to the debenture trustee and TXU Gas Company. No
resignation or removal of the debenture trustee and no appointment of a
successor trustee will be effective until the acceptance of appointment by a
successor trustee. So long as no Event of Default under the subordinated
indenture or event which, after notice or lapse of time, or both, would become
an Event of Default under the subordinated indenture has occurred and is
continuing and except with respect to a trustee appointed by act of the holders,
if TXU Gas Company has delivered to the debenture trustee a resolution of its
Board of Directors appointing a successor trustee and the successor has accepted
that appointment in accordance with the terms of the respective subordinated
indenture, the debenture trustee will be deemed to have resigned and the
successor will be deemed to have been appointed as trustee in accordance with
the subordinated indenture (Subordinated Indenture, Section 910).

      NOTICES

      Notices to holders of subordinated debentures will be given by mail to the
addresses of the holders as they may appear in the security register for the
subordinated debentures (Subordinated Indenture, Section 106).

      TITLE

      TXU Gas Company, the debenture trustee, and any agent of TXU Gas Company
or the debenture trustee, may treat the person in whose name any subordinated
debenture is registered as the absolute owner of the subordinated debenture,
whether or not the subordinated debenture may be overdue, for the purpose of
making payments and for all other purposes irrespective of notice to the
contrary (Subordinated Indenture, Section 308).

      GOVERNING LAW

      The subordinated indenture and the subordinated debentures will be
governed by, and construed in accordance with, the laws of the State of New York
(Subordinated Indenture, Section 112).

      CONCERNING THE DEBENTURE TRUSTEE

      The debenture trustee under the subordinated indenture will be The Bank of
New York. In addition to acting as debenture trustee, The Bank of New York will
act as property trustee under the trust agreement and as guarantee trustee under
the guarantee. Its affiliate, The Bank of New York (Delaware), will act as the
Delaware trustee under the trust agreement. In addition, The Bank of New York
acts, and may act, as trustee under various indentures and trusts of TXU Gas
Company, TXU Corp and other affiliates. TXU Gas Company, TXU Corp and other
affiliates maintain deposit accounts and credit and liquidity facilities and
conduct other banking transactions with the debenture trustee in the ordinary
course of their businesses.


                              PLAN OF DISTRIBUTION

      The debt securities and the preferred trust securities described in this
prospectus may be offered (a) through agents; (b) through underwriters or
dealers; or (c) directly to purchasers.

      BY AGENTS

      The debt securities and preferred trust securities may be sold through
agents designated by TXU Gas Company.


                                    -30-
<PAGE>


      BY UNDERWRITERS

      If underwriters are used in any sale of debt securities or preferred trust
securities, the underwriters will acquire the securities sold for their own
account. The underwriters may resell those securities in one or more
transactions, including negotiated transactions, at a fixed public offering
price or at varying prices determined at the time of sale. Underwriters may sell
the securities directly or through underwriting syndicates represented by
managing underwriters. The obligations of the underwriters to purchase the
securities will be subject to specific conditions. The underwriters in any
underwritten offering will be obligated to purchase all the offered securities
if any are purchased. If a dealer is used in the sale, TXU Gas Company or TXU
Gas Capital will sell the securities to the dealer as principal. The dealer may
then resell the securities at varying prices determined at the time of resale.

      DIRECT SALES

      Debt securities and preferred trust securities may also be sold directly
by TXU Gas Company. In that case, no underwriters or agents would be involved.

      GENERAL INFORMATION

      Underwriters, dealers and agents that participate in any distribution of
debt securities or preferred trust securities may be underwriters as defined in
the Securities Act and any discounts or commissions received by them from TXU
Gas Company or TXU Gas Capital and any profit on the resale by them of those
securities may be treated as underwriting discounts under the Securities Act.
Any underwriters, dealers or agents will be identified and their compensation
described in a prospectus supplement.

      TXU Gas Company or TXU Gas Capital may authorize agents and underwriters
to solicit offers by specified institutions to purchase debt securities or
preferred trust securities at the public offering price and on terms described
in the applicable prospectus supplement.

      TXU Gas Company may have agreements with agents, underwriters and dealers
to indemnify them against specified civil liabilities, including liabilities
under the Securities Act, or to contribute with respect to payments which the
agents, underwriters, dealers and remarketing firms may be required to make.

      Neither the debt securities nor the preferred trust securities has an
established trading market. TXU Gas Company may decide to list any series of
those securities on an exchange. However, TXU Gas Company will not be obligated
to list securities on an exchange unless it states otherwise in a prospectus
supplement. TXU Gas Company cannot assure that there will be any liquidity of
the trading market for any series of debt securities or preferred trust
securities.

      Agents, underwriters and dealers may engage in transactions with, or
perform services for, TXU Gas Company or its subsidiaries in the ordinary course
of business.

      The consolidated financial statements included in the latest Annual Report
of TXU Gas Company on Form 10-K, incorporated in this prospectus by reference,
have been audited by Deloitte & Touche LLP, independent auditors, as stated in

      With respect to any unaudited condensed consolidated interim financial
information included in TXU Gas Company's Quarterly Reports on Form 10-Q which
are or will be incorporated in this prospectus by reference, Deloitte & Touche
LLP has applied limited procedures in accordance with professional standards for
reviews of that information. As stated in any of their reports included in TXU
Gas Company's Quarterly Reports on Form 10-Q, which are or will be incorporated
in this prospectus by reference, Deloitte & Touche LLP did not audit and did not
express an opinion on that interim financial information. Accordingly, the
degree of reliance on the reports on that information should be restricted in
light of the limited nature of the review procedures applied. Deloitte & Touche
LLP is not subject to the liability provisions of Section 11 of the Securities
Act for any of their reports on the unaudited condensed consolidated interim
financial information because those reports are not "reports" or a "part" of the
registration statement filed under the Securities Act with respect to the debt
securities or preferred trust securities prepared or certified by an accountant
within the meaning of Sections 7 and 11 of the Securities Act.

      Matters of Delaware law relating to the validity of the preferred trust

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Article 2.02-1 of the Texas Business Corporation Act permits TXU Gas
Company, in certain circumstances, to indemnify any present or former director,
officer, employee or agent of TXU Gas Company against judgments, penalties,
fines, settlements and reasonable expenses incurred in connection with a
proceeding in which any such person was, is or is threatened to be, made a party
by reason of holding that office or position, but only to a limited extent for
obligations resulting from a proceeding in which the person is found liable on
the basis that a personal benefit was improperly received or in circumstances in
which the person is found liable in a derivative suit brought on behalf of TXU
Gas Company.

     Article Eight of the Restated Articles of Incorporation of TXU Gas Company,
as amended, provides as follows:

     "No director of this Corporation will be liable to this Corporation or its
shareholders for monetary damages for an act or omission in such director's
capacity as a director of this Corporation, except this Article Eight does not
eliminate or limit the liability of a director of this Corporation for (1) a
breach of the director's duty of loyalty to this Corporation or its
shareholders, (2) an act or omission not in good faith or that involves
intentional misconduct or a knowing violation of the law, (3) a transaction from
which the director received an improper benefit, whether or not the benefit
resulted from an action taken within the scope of the director's office, (4) an
act or omission for which the liability of the director is expressly provided
for by statute, or (5) an act related to an unlawful stock repurchase or payment
of a dividend."


                                    II-1
<PAGE>


     Section 1 of Article XIII of TXU Gas Company's Bylaws is as follows:

     "Section 1. The corporation shall indemnify any person who (1) is or was a
director, officer, employee or agent of the corporation, or (2) while a
director, officer, employee or agent of the corporation, its divisions or
subsidiaries, is or was serving at the request of the corporation, pursuant to a
resolution adopted by the Board of Directors, as a director, officer, partner,
venturer, proprietor, Trustee, employee, agent or similar functionary of another
foreign or domestic corporation, partnership, joint venture, sole
proprietorship, trust, employee benefit plan or other enterprise, to the fullest
extent that a corporation may or is required to grant indemnification to a
director under the Texas Business Corporation Act. The corporation, pursuant to
a resolution adopted by the Board of Directors, may indemnify any such person to
such further extent as permitted by law."

     TXU Gas Company has entered into agreements with certain of its officers
and directors which provide, among other things, for their indemnification by
TXU Gas Company to the fullest extent permitted by Texas law.

     TXU Gas Company has insurance covering its expenditures which might arise
in connection with its lawful indemnification of its directors and officers for
their liabilities and expenses. Directors and officers of TXU Gas Company also
have insurance which insures them against certain other liabilities and
expenses.

ITEM 17. UNDERTAKINGS.

a.   The undersigned registrants hereby undertake:

     (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:

             (i)      To include any prospectus required by Section 10(a)(3) of
     the Securities Act of 1933;

             (ii) To reflect in the prospectus any facts or events arising after
     the effective date of the registration statement (or the most recent
     post-effective amendment thereof) which, individually or in the aggregate,
     represent a fundamental change in the information set forth in the
     registration statement. Notwithstanding the foregoing, any increase or
     decrease in volume of securities offered (if the total dollar value of
     securities offered would not exceed that which was registered) and any
     deviation from the low or high end of the estimated maximum offering range
     may be reflected in the form of prospectus filed with the Commission
     pursuant to Rule 424(b) under the Securities Act of 1933 if, in the
     aggregate, the changes in volume and price represent no more than a 20%
     change in the maximum aggregate offering price set forth in the
     "Calculation of Registration Fee" table in the effective registration
     statement; and

             (iii) To include any material information with respect to the plan
     of distribution not previously disclosed in the registration statement or
     any material change to such information in the registration statement;

     provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if
     the registration statement is on Form S-3, Form S-8 or Form F-3, and the
     information required to be included in a post-effective amendment by those
     paragraphs is contained in periodic reports filed with or furnished to the
     Commission by the registrant pursuant to Section 13 or 15(d) of the
     Exchange Act that are incorporated by reference in the registration
     statement.

     (2) That, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

     (3) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.

     (4) That, for purposes of determining any liability under the Securities
Act of 1933, each filing of the registrant's Annual Report pursuant to Section
13(a) or Section 15(d) of the Exchange Act that is incorporated by reference in
the registration statement shall be deemed to be a new registration statement
relating to the securities offered herein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

b. Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provisions described under Item 15 above, or
otherwise, the registrants have been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the registrants of expenses incurred or paid by a director, officer or
controlling person of any registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrants will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

                     ---------------------------------------------
represents and warrants to the several Underwriters that:

              (a) The Company and three of its financing subsidiaries (the
         "Trusts") have filed with the Securities and Exchange Commission (the
         "Commission") a registration statement on Form S-3 on            , 1999
         (Registration Nos. 333-       , 333-            -01, 333-       -02 and
         333-        -03) for the registration under the Securities Act of 1933,
         as amended (the "Securities Act") of $500,000,000 aggregate amount of
         (i) the Company's unsecured debt securities ("Debt Securities") and
         (ii) the preferred trust securities of the Trusts, and a principal
         amount of the Company's junior subordinated debentures and guarantees
         and other obligations of the Company in respect of such preferred
         trust securities. Such registration statement ("Registration Statement
         No. 333-       ") became effective on                   , 1999. The
         Company has also filed with the Commission under the Securities Act, a
         registration statement on Form S-3 on January 7, 1998 (Registration
         Nos. 333-43811 and 333-43811-01) for the registration of $275,000,000
         aggregate amount (i) the Company's Debt Securities and (ii) certain
         trust securities of ENSERCH Capital I, which has been renamed TXU Gas
         Capital I, and related securities of the Company, of which all but
         $100,000,000 aggregate principal amount of the Company's Debt
         Securities have been previously issued. Such registration
         statement was declared effective by the Commission on January 13, 1998.
         Such registration statement ("Registration Statement No. 333-43811")
         was amended by Post-Effective Amendment No. 1, which was filed on
         January 21, 1998 and became effective on January 23, 1998. References
         herein to the term "Registration Statement" as of any date shall be
         deemed to refer to each of Registration Statement Nos. 333-      and
         Registration Statement No. 333-43811, each as amended or supplemented
         to such date, including all documents incorporated by reference therein
         as of such date pursuant to Item 12 of Form S-3 ("Incorporated
         Documents"). References herein to the term "Prospectus" as of any given
         date shall be deemed to refer to the combined prospectus relating to
         the securities registered under Registration Statement 333-      and
         the securities registered and remaining unissued under Registration
         Statement 333-43811 that forms a part of Registration Statement No.
         333-       , as amended or supplemented as of such date (other than by
         amendments or supplements relating to securities other than the
         Securities), including all Incorporated Documents as of such date and
         including any prospectus supplement relating to the Securities;
         provided that if the Company files a registration statement with the
         Commission pursuant to Rule 462(b) of the General Rules and Regulations
         of the Securities Act Regulations (the "Rule 462(b) Registration
         Statement"), then after such filing, all references to "Registration
         Statement" shall be deemed to include the Rule 462(b) Registration
         Statement. References herein to the term "Effective Date" shall be
         deemed to refer to the time and date Registration Statement No.
         333-          or the Rule 462(b) Registration Statement, as the case
         may be, was declared effective. The Company will not file any amendment
         to the Registration Statement or supplement to the Prospectus on or
         after the date of this Agreement and prior to the Closing Date, as
         hereinafter defined, without prior notice to the Underwriters, or to
         which Counsel for the Underwriters shall reasonably object in writing.
         For the purposes of this Agreement, any Incorporated Document filed
         with the Commission on or after the date of this Agreement and prior to
         the Closing Date, as hereinafter defined, shall be deemed an amendment
         or supplement to the Registration Statement and the Prospectus.

                  (b) On the Effective Date, the Registration Statement and the
         Prospectus complied in all material respects and at the Closing Date,
         as hereinafter defined, the Registration Statement, the Prospectus and
         the Indenture will comply in all material respects with the applicable
         provisions of the Securities Act, the Trust Indenture Act of 1939, as
         amended ("Trust Indenture Act"), and the applicable rules and
         regulations of the Commission thereunder; on the Effective Date the
         Registration Statement did not, and at the Closing Date, as hereinafter
         defined, the Registration Statement will not, contain an untrue
         statement of a material fact or omit to state a material fact required
         to be stated therein or necessary to make the statements therein not
         misleading; on the Effective Date the Prospectus did not, and at the
         Closing Date, as hereinafter defined, and on the date it is filed with
         the Commission pursuant to Rule 424 of the General Rules and
         Regulations of the Securities Act ("Rule 424"), the Prospectus will
         not, contain an untrue statement of a material fact or omit to state a
         material fact necessary in order to make the statements therein, in the
         light of the circumstances under which they were made, not misleading;
         and on said dates the Incorporated Documents, taken together as a
         whole, complied or will comply in all material respects with the
         applicable provisions of the Securities Exchange Act of 1934, as
         amended (the "Exchange Act"), and the applicable rules and regulations
         of the Commission thereunder, and, when read together with the
         Prospectus on said dates did not and will not contain an untrue
         statement of a material fact or omit to state a material fact required
         to be stated therein or necessary to make the statements therein, in
         the light of the circumstances under which they were made, not
         misleading; provided that the foregoing representations and warranties
         in this paragraph (b) shall not apply to statements or omissions made
         in reliance upon information furnished in writing to the Company by, or
         on behalf of, any Underwriter for use in connection with the
         preparation of the Registration Statement or the Prospectus or to any
         statements in or omissions from the Statements of Eligibility and
         Qualification under the Trust Indenture Act, or amendments thereto,
         filed as exhibits to the Registration Statement.

                  (c) The consummation of the transactions herein contemplated
         and the fulfillment of the terms hereof will not result in a breach of
         any of the terms or provisions of, or constitute a default under, any
         indenture, mortgage, deed of trust or other agreement or instrument to
         which the Company is now a party.

                   4.      Purchase and Sale.
                           -----------------

                  (a) On the basis of the representations and warranties herein
         contained, and subject to the terms and conditions herein set forth,
         the Company shall sell to each of the Underwriters, and each
         Underwriter shall purchase from the Company, at the time and place
         herein specified, severally and not jointly, the aggregate amount of
         the Securities set forth opposite the name of such Underwriter in
         Schedule II attached hereto, at the purchase price or prices set forth
         in Schedule I hereto.

                  (b)      The Company shall pay to the Underwriters a
         commission equal to      % of the aggregate principal amount
         of the Securities.

                   5. Time and Place of Closing. Delivery of the Securities,
                      -------------------------
against payment of the aggregate purchase price therefor, plus accrued interest
thereon, if any, from the date of original issuance to the date of payment for
and delivery of the Securities by wire transfer in federal funds shall be made
at the offices of Thelen Reid & Priest LLP, 40 West 57th Street, New York, New
York, at 10:00 A.M., New York Time, on              , or at such other place,
time and date as shall be agreed upon in writing by the Company and you or
established in accordance with the following paragraph. The hour and date of
such delivery and payment are herein called the "Closing Date". The Securities
shall be delivered [to The Depository Trust Company or to The Bank of New York,
as custodian for The Depository Trust Company, in fully registered global form
registered in the name of Cede & Co. for the respective accounts specified by
you not later than the close of business on the business day preceding the
Closing Date] [to you for the respective accounts of the several Underwriters,
registered in such names and in such denominations as you shall request in
writing not less than one full business day prior to the Closing Date]. The
Company agrees to make the Securities available to you for checking purposes
not later than 10:00 A.M., New York Time, on the last business day preceding
the Closing Date at the offices of Thelen Reid & Priest LLP, 40 West 57th
Street, New York, New York, 10019, or at such other place as the Company may
specify.

                  If any Underwriter shall fail or refuse (otherwise than for
some reason sufficient to justify, in accordance with the terms hereof, the
cancellation or termination of its obligations hereunder) to purchase and pay
for the principal amount of the Securities that such Underwriter has agreed to
purchase and pay for hereunder, the Company shall immediately give notice to the
other Underwriters of the default of such Underwriter, and the other
Underwriters shall have the right within 24 hours after the receipt of such
notice to determine to purchase, or to procure one or more others, who are
members of the National Association of Securities Dealers, Inc. ("NASD") (or, if
not members of the NASD, who are not eligible for membership in the NASD and who
agree (i) to make no sales within the United States, its territories or its
possessions or to persons who are citizens thereof or residents therein and (ii)
in making sales to comply with the NASD's Conduct Rules) and satisfactory to the
Company, to purchase, upon the terms herein set forth, the principal amount of
the Securities that the defaulting Underwriter had agreed to purchase. If any
non-defaulting Underwriter or Underwriters shall determine to exercise such
right, such Underwriter or Underwriters shall give written notice to the Company
of the determination in that regard within 24 hours after receipt of notice of
any such default, and thereupon the Closing Date shall be postponed for such
period, not exceeding three business days, as the Company shall determine. If in
the event of such a default no non-defaulting Underwriter shall give such
notice, then this Agreement may be terminated by the Company, upon like notice
given to the non-defaulting Underwriters, within a further period of 24 hours.
If in such case the Company shall not elect to terminate this Agreement it shall
have the right, irrespective of such default:

                  (a) to require each non-defaulting Underwriter to purchase and
         pay for the respective number or amount of the Securities that it had
         agreed to purchase hereunder as hereinabove provided and, in addition,
         the principal amount of the Securities that the defaulting Underwriter
         shall have so failed to purchase up to a principal amount thereof equal
         to one-ninth (1/9) of the principal amount of Securities that such
         non-defaulting Underwriter has otherwise agreed to purchase hereunder,
         and/or

                  (b) to procure one or more persons, reasonably acceptable to
         the Representatives, who are members of the NASD (or, if not members of
         the NASD, who are not eligible for membership in the NASD and who agree
         (i) to make no sales within the United States, its territories or its
         possessions or to persons who are citizens thereof or residents therein
         and (ii) in making sales to comply with the NASD's Conduct Rules), to
         purchase, upon the terms herein set forth, either all or a part of the
         principal amount of the Securities that such defaulting Underwriter
         had agreed to purchase or that portion thereof that the remaining
         Underwriters shall not be obligated to purchase pursuant to the
         foregoing clause (a).

In the event the Company shall exercise its rights under (a) and/or (b) above,
the Company shall give written notice thereof to the non-defaulting Underwriters
within such further period of 24 hours, and thereupon the Closing Date shall be
postponed for such period, not exceeding three business days, as the Company
shall determine.

                  In the computation of any period of 24 hours referred to in
this Section 5, there shall be excluded a period of 24 hours in respect of each
Saturday, Sunday or legal holiday that would otherwise be included in such
period of time.

                  Any action taken by the Company under this Section 5 shall not
relieve any defaulting Underwriter from liability in respect of any default of
such Underwriter under this Agreement. Termination by the Company under this
Section 5 shall be without any liability on the part of the Company or any
non-defaulting Underwriter, except as otherwise provided in Sections 6(g) and 9
hereof.

                  6. Covenants of the Company. The Company agrees that:
                     ------------------------

                  (a) It will promptly deliver to each of you a signed copy of
         the Registration Statement as originally filed or, to the extent a
         signed copy is not available, a conformed copy, certified by an officer
         of the Company to be in the form as originally filed, including all
         Incorporated Documents and exhibits and of all amendments thereto.

                  (b) It will deliver to you, as soon as practicable after the
         date hereof, as many copies of the Prospectus as of such date as you
         may reasonably request.

                  (c) It will cause the Prospectus to be filed with the
         Commission pursuant to Rule 424 as soon as practicable and advise you
         of the issuance of any stop order under the Securities Act with respect
         to the Registration Statement or the institution of any proceedings
         therefor of which the Company shall have received notice. The Company
         will use its best efforts to prevent the issuance of any such stop
         order and to secure the prompt removal thereof if issued.

                  (d) If, during such period of time (not exceeding nine months)
         after the Prospectus has been filed with the Commission pursuant to
         Rule 424 as in the opinion of Counsel for the Underwriters a prospectus
         covering the Securities is required by law to be delivered in
         connection with sales by an Underwriter or dealer, any event relating
         to or affecting the Company or of which the Company shall be advised in
         writing by you shall occur that in the Company's reasonable opinion
         after consultation with Counsel for the Underwriters
         should be set forth in a supplement to, or an amendment of, the
         Prospectus in order to make the Prospectus not misleading in the light
         of the circumstances when it is delivered to a purchaser, the Company
         will, at its expense, amend or supplement the Prospectus by either (i)
         preparing and furnishing to you at the Company's expense a reasonable
         number of copies of a supplement or supplements or an amendment or
         amendments to the Prospectus or (ii) making an appropriate filing
         pursuant to Section 13 of the Exchange Act, which will supplement or
         amend the Prospectus so that, as supplemented or amended, it will not
         contain any untrue statement of a material fact or omit to state any
         material fact necessary in order to make the statements therein, in the
         light of the circumstances when the Prospectus is delivered to a
         purchaser, not misleading; provided that should such event relate
         solely to the activities of any of the Underwriters, then the
         Underwriters shall assume the expense of preparing and furnishing any
         such amendment or supplement. In case any Underwriter is required to
         deliver a prospectus after the expiration of nine months from the date
         the Prospectus is filed with the Commission pursuant to Rule 424, the
         Company, upon such Underwriter's request, will furnish to such
         Underwriter, at the expense of such Underwriter, a reasonable quantity
         of a supplemental prospectus or supplements to the Prospectus complying
         with Section 10(a) of the Securities Act.

                  (e) It will make generally available to its security holders,
         as soon as practicable, an earnings statement (which need not be
         audited) covering a period of at least twelve months beginning not
         earlier than the first day of the month next succeeding the month in
         which occurred the effective date of the Registration Statement as
         defined in Rule 158 under the Securities Act.

                  (f) It will furnish such proper information as may be lawfully
         required and otherwise cooperate in qualifying the Securities for offer
         and sale under the blue-sky laws of such jurisdictions as you may
         designate, provided that the Company shall not be required to qualify
         as a foreign corporation or dealer in securities, to file any consents
         to service of process under the laws of any jurisdiction, or to meet
         any other requirements deemed by the Company to be unduly burdensome.

                  (g) It will, except as herein provided, pay all expenses and
         taxes (except transfer taxes) in connection with (i) the preparation
         and filing by it of the Registration Statement, (ii) the issuance and
         delivery of the Securities as provided in Section 5 hereof, (iii) the
         qualification of the Securities under blue-sky laws (including counsel
         fees not to exceed $7,500), and (iv) the printing and delivery to the
         Underwriters of reasonable quantities of the Registration Statement
         and, except as provided in Section 6(d) hereof, of the Prospectus. The
         Company shall not, however, be required to pay any amount for any
         expenses of yours or any of the Underwriters, except that, if this
         Agreement shall be terminated in accordance with the provisions of
         Section 7, 8 or 10 hereof, the Company will reimburse you for the fees
         and disbursements of Counsel for the Underwriters, whose fees and
         disbursements the Underwriters agree to pay in any other event, and
         will reimburse the Underwriters for their reasonable out-of-pocket
         expenses, in an aggregate amount not exceeding $5,000, incurred in
         contemplation of the performance of this Agreement. The Company shall
         not in any event be liable to any of the several Underwriters for
         damages on account of loss of anticipated profits.

                  (h) During the period from the date of this Agreement to the
         Closing Date, the Company will not, without the prior written consent
         of the Representatives, directly or indirectly, publicly issue, sell,
         offer or contract to sell, in the market in which the Securities are
         being offered and sold, any securities of the Company or any of its
         subsidiaries which are of the same class as the Securities.

                   7. Conditions of Underwriters' Obligations. The obligations
                      ---------------------------------------
of the Underwriters to purchase and pay for the Securities shall be subject to
the accuracy of the representations and warranties made herein on the part of
the Company, to the performance by the Company of its obligations to be
performed hereunder prior to the Closing Date, and to the following conditions:

                  (a) The Prospectus shall have been filed with the Commission
         pursuant to Rule 424 prior to 5:30 P.M., New York Time, on the second
         business day after the date of this Agreement, or such other time and
         date as may be approved by you.

                  (b) No stop order suspending the effectiveness of the
         Registration Statement shall be in effect, and no proceedings for that
         purpose shall be pending before, or threatened by, the Commission on
         the Closing Date; and you shall have received a certificate, dated the
         Closing Date and signed by an officer of the Company, to the effect
         that no such stop order is in effect and that no proceedings for such
         purpose are pending before, or to the knowledge of the Company
         threatened by, the Commission.

                  (c) On the Closing Date, you shall have received from Worsham,
         Forsythe & Wooldridge, L.L.P., General Counsel for the Company, Thelen
         Reid & Priest LLP, of counsel for the Company, and Winthrop, Stimson,
         Putnam & Roberts, Counsel for the Underwriters, opinions in
         substantially the form and substance prescribed in Schedules III, IV
         and V hereto (i) with such changes therein as may be agreed upon by the
         Company and you, with the approval of Counsel for the Underwriters, and
         (ii) if the Prospectus relating to the Securities shall be supplemented
         or amended after the Prospectus shall have been filed with the
         Commission pursuant to Rule 424, with any changes therein necessary to
         reflect such supplementation or amendment.

                  (d) On and as of the Closing Date, you shall have received
         from Deloitte & Touche LLP a letter to the effect that (i) they are
         independent certified public accountants with respect to the Company,
         within the meaning of the Securities Act and the applicable published
         rules and regulations thereunder, (ii) in their opinion, the financial
         statements audited by them and included or incorporated by reference in
         the Prospectus comply as to form in all material respects with the
         applicable accounting requirements of the Exchange Act and the
         applicable published rules and regulations thereunder, (iii) on the
         basis of a reading of the unaudited amounts of operating revenues and
         net income included or incorporated by reference in the Prospectus and
         the related financial statements from which these amounts were derived,
         the latest available unaudited financial statements of the Company and
         the minute books of the Company and inquiries of officers of the
         Company and of certain material direct or indirect subsidiaries of the
         Company who have responsibility for financial and accounting matters
         (it being understood that the foregoing procedures do not constitute an
         audit made in accordance with generally accepted auditing standards and
         would not necessarily reveal matters of significance with respect to
         the comments made in such letter, and accordingly that Deloitte &
         Touche LLP makes no representation as to the sufficiency of such
         procedures for the several Underwriters' purposes), nothing has come to
         their attention which caused them to believe that (A) the unaudited
         financial statements of the Company incorporated by reference in the
         Prospectus were not determined in accordance with generally accepted
         accounting principles applied on a basis substantially consistent with
         that of the corresponding amounts in the latest available audited
         financial statements of the Company, (B) the unaudited amounts of
         operating revenues and net income of the Company included or
         incorporated by reference in the Prospectus were not determined on a
         basis substantially consistent with that of the corresponding amounts
         in the audited statements of income of the Company, incorporated by
         reference in the Prospectus, (C) for the twelve months ended         ,
         if available, there were any decreases in operating revenues or net
         income as compared with the comparable period of the preceding year,
         and (D) at a specified date not more than seven days prior to the date
         of such letter, there was any change in the capital stock of the
         Company, short-term bank loans, commercial paper, notes payable to TXU
         Corp or long-term debt of the Company or decrease in its net assets, in
         each case as compared with amounts shown in the most recent balance
         sheets of the Company incorporated by reference in the Prospectus,
         except in all instances for changes or decreases that the Prospectus
         discloses have occurred or may occur or which are occasioned by the
         declaration of a regular quarterly dividend or the acquisition of
         long-term debt for sinking fund purposes, or which are
         described in such letter, and (iv) they have compared the dollar
         amounts (or percentages or ratios derived from such dollar amounts) and
         other financial information included or incorporated by reference in
         the Registration Statement and the Prospectus as reasonably requested
         by you (in each case to the extent that such dollar amounts,
         percentages and other financial information are derived from the
         general accounting records of the Company and its consolidated
         subsidiaries subject to the internal controls of the accounting system
         of such companies or are derived indirectly from such records by
         analysis or computation) with the results obtained from inquiries, a
         reading of such general accounting records and other procedures
         specified in such letter, and have found such dollar amounts,
         percentages and other financial information to be in agreement with
         such results, except as otherwise specified in such letter.

                  (e) Since the most recent dates as of which information is
         given in the Registration Statement or the Prospectus there shall not
         have been any material adverse change in the business, property or
         financial condition of the Company and its subsidiaries, considered as
         a whole, and, since such dates, there shall not have been any material
         transaction entered into by the Company and its subsidiaries, in each
         case other than transactions in the ordinary course of business and
         transactions contemplated by the Registration Statement or Prospectus,
         and at the Closing Date you shall have received a certificate to such
         effect dated the Closing Date and signed by an officer of the Company.

                  (f) All legal proceedings to be taken in connection with the
         issuance and sale of the Securities as described in the Prospectus
         shall have been satisfactory in form and substance to Counsel for the
         Underwriters.

                  (g) Since the date of this agreement, neither Moody's Investor
         Services nor Standard and Poor's Corporation shall have downgraded or
         publicly announced that it has under surveillance or review, with
         possible negative implications, its rating of any securities of the
         Company which are of the same class as the Securities or the financial
         condition of the Company.

                  In case any of the conditions specified above in this Section
7 shall not have been fulfilled, this Agreement may be terminated by the
Representatives upon notice thereof to the Company. Any such termination shall
be without liability of any party to any other party except as otherwise
provided in Sections 6(g) and 9 hereof.

                   8. Conditions of Company's Obligations. The obligation of the
                      -----------------------------------
Company to deliver the Securities shall be subject to the conditions that the
Prospectus shall have been filed with the Commission pursuant to Rule 424 prior
to 5:30 P.M., New York Time, on the second business day after the date of this
Agreement or such other time and date as may be approved by the Company, and no
stop order suspending the effectiveness of the Registration Statement shall be
in effect at the Closing Date and no proceedings for that purpose shall be
pending before, or threatened by, the Commission at the Closing Date. In case
these conditions shall not have been fulfilled, this Agreement may be terminated
by the Company upon notice thereof to you. Any such termination shall be without
liability of any party to any other party except as otherwise provided in
Sections 6(g) and 9 hereof.

                   9.      Indemnification.
                           ---------------

                  (a) The Company shall indemnify, defend and hold harmless each
         Underwriter and each person who controls any Underwriter within the
         meaning of Section 15 of the Securities Act from and against any and
         all losses, claims, damages or liabilities, joint or several, to which
         they or any of them may become subject under the Securities Act or any
         other statute or common law and shall reimburse each such Underwriter
         and controlling person for any legal or other expenses (including, to
         the extent hereinafter provided, reasonable counsel fees) incurred by
         them in connection with investigating any such losses, claims, damages
         or liabilities or in connection with defending any actions, insofar as
         such losses, claims, damages, liabilities, expenses or actions arise
         out of or are based upon any untrue statement or alleged untrue
         statement of a material fact contained in the Registration Statement or
         the Prospectus (or any amendment or supplement thereto), or the
         omission or alleged omission to state therein a material fact required
         to be stated therein or necessary to make the statements therein in the
         light of the circumstances under which they were made not misleading;
         provided, however, that the indemnity agreement contained in this
         Section 9 shall not apply to any such losses, claims, damages,
         liabilities, expenses or actions arising out of, or based upon, any
         such untrue statement or alleged untrue statement, or any such omission
         or alleged omission, if such statement or omission was made in reliance
         upon information furnished in writing to the Company by or on behalf of
         any Underwriter, through the Representatives or Counsel for the
         Underwriters, for use in connection with the preparation of the
         Registration Statement or the Prospectus or any amendment or supplement
         to either thereof, or arising out of, or based upon, statements in or
         omissions from that part of the Registration Statement that shall
         constitute the Statements of Eligibility and Qualification under the
         Trust Indenture Act of any Trustee with respect to any indenture
         qualified pursuant to the Registration Statement; and provided further,
         that the indemnity agreement contained in this Section 9 shall not
         inure to the benefit of any Underwriter (or of any person controlling
         such Underwriter) on account of any such losses, claims, damages,
         liabilities, expenses or actions arising from the sale of the
         Securities to any person if a copy of the Prospectus (including any
         amendment or supplement thereto if any amendments or supplements
         thereto shall have been furnished to the Underwriters at or prior to
         the time of written confirmation of the sale involved and such
         amendment or supplement corrected the alleged omission or alleged
         untrue statement in the Prospectus) (exclusive of the Incorporated
         Documents) shall not have been given or sent to such person by or on
         behalf of such Underwriter with or prior to the written
         confirmation of the sale involved. The indemnity agreement of the
         Company contained in this Section 9 and the representations and
         warranties of the Company contained in Section 3 hereof shall remain
         operative and in full force and effect regardless of any termination of
         this Agreement or of any investigation made by or on behalf of any
         Underwriter or any such controlling person, and shall survive the
         delivery of the Securities.

                  (b) Each Underwriter shall indemnify, defend and hold harmless
         the Company, its officers and directors, and each person who controls
         the Company within the meaning of Section 15 of the Securities Act,
         from and against any and all losses, claims, damages or liabilities,
         joint or several, to which they or any of them may become subject under
         the Securities Act or any other statute or common law and shall
         reimburse each of them for any legal or other expenses (including, to
         the extent hereinafter provided, reasonable counsel fees) incurred by
         them in connection with investigating any such losses, claims, damages
         or liabilities or in connection with defending any actions, insofar as
         such losses, claims, damages, liabilities, expenses or actions
         arise out of or are based upon any untrue statement or alleged
         untrue statement of a material fact contained in the Registration
         Statement or the Prospectus (or any amendment or supplement thereto),
         or the omission or alleged omission to state therein a material fact
         required to be stated therein or necessary to make the statements
         therein not misleading, if such statement or omission was made in
         reliance upon and in conformity with information furnished in writing
         to the Company by or on behalf of such Underwriter, through the
         Representatives or Counsel for the Underwriters, for use in connection
         with the preparation of the Registration Statement or the Prospectus or
         any amendment or supplement to either thereof. Each Underwriter hereby
         furnishes to the Company in writing expressly for use in the Prospectus
         [indicate topics addressed and location in the Prospectus.] The
         indemnity agreement of the respective Underwriters contained in this
         Section 9 shall remain operative and in full force and effect
         regardless of any termination of this Agreement or of any investigation
         made by or on behalf of the Company, its directors or its officers, any
         such Underwriter, or any such controlling person, and shall survive the
         delivery of the Securities.

                  (c) The Company and the several Underwriters each shall, upon
         the receipt of notice of the commencement of any action against it or
         any person controlling it as aforesaid, in respect of which indemnity
         may be sought on account of any indemnity agreement contained herein,
         promptly give written notice of the commencement thereof to the party
         or parties against whom indemnity shall be sought hereunder, but the
         omission so to notify such indemnifying party or parties of any such
         action shall not relieve such indemnifying party or parties from any
         liability which it or they may have to the indemnified party otherwise
         than on account of such indemnity agreement. In case such notice of any
         such action shall be so given, such indemnifying party shall be
         entitled to participate at its own expense in the defense, or, if it so
         elects, to assume (in conjunction with any other indemnifying parties)
         the defense of such action, in which event such defense shall be
         conducted by counsel chosen by such indemnifying party or parties and
         satisfactory to the indemnified party or parties who shall be defendant
         or defendants in such action, and such defendant or defendants shall
         bear the fees and expenses of any additional counsel retained by them;
         but if the indemnifying party shall elect not to assume the defense of
         such action, such indemnifying party will reimburse such indemnified
         party or parties for the reasonable fees and expenses of any counsel
         retained by them; provided, however, if the defendants in any such
         action include both the indemnified party and the indemnifying party
         and counsel for the indemnifying party shall have reasonably concluded
         that there may be a conflict of interest involved in the representation
         by such counsel of both the indemnifying party and the indemnified
         party, the indemnified party or parties shall have the right to select
         separate counsel, satisfactory to the indemnifying party, to
         participate in the defense of such action on behalf of such indemnified
         party or parties (it being understood, however, that the indemnifying
         party shall not be liable for the expenses of more than one separate
         counsel representing the indemnified parties who are parties to such
         action). Each of the Company and the Underwriters agrees that without
         the other party's prior written consent, which consent shall not be
         unreasonably withheld, it will not settle, compromise or consent to the
         entry of any judgment in any claim in respect of which indemnification
         may be sought under the indemnification provisions of this Agreement,
         unless such settlement, compromise or consent (i) includes an
         unconditional release of such other party from all liability arising
         out of such claim and (ii) does not include a statement as to or an
         admission of fault, culpability or a failure to act by or on behalf of
         such other party.

                  (d) If the indemnification provided for in sub-paragraph (a)
         or (b) above shall be unenforceable under applicable law by an
         indemnified party, each indemnifying party agrees to contribute to such
         indemnified party with respect to any and all losses, claims, damages,
         liabilities and expenses for which each such indemnification provided
         for in subparagraph (a) or (b) above shall be unenforceable, in such
         proportion as shall be appropriate to reflect (i) the relative fault of
         each indemnifying party on the one hand and the indemnified party on
         the other in connection with the statements or omissions which have
         resulted in such losses, claims, damages, liabilities and expenses,
         (ii) the relative benefits received by the Company on the one hand and
         the Underwriters on the other hand from the offering of the Securities
         pursuant to this Agreement, and (iii) any other relevant equitable
         considerations; provided, however, that no indemnified party guilty of
         fraudulent misrepresentation (within the meaning of Section 11(f) of
         the Securities Act) shall be entitled to contribution from any
         indemnifying party not guilty of such fraudulent misrepresentation.
         Relative fault shall be determined by reference to, among other things,
         whether the untrue or alleged untrue statement of a material fact or
         the omission or alleged omission to state a material fact relates to
         information supplied by such indemnifying party or the indemnified
         party and each such party's relative intent, knowledge, access to
         information and opportunity to correct or prevent such untrue statement
         or omission. The Company and each of the Underwriters agree that it
         would not be just and equitable if contributions pursuant to this
         subparagraph (d) were to be determined by pro rata allocation (even if
         the Underwriters were treated as one entity for such purpose) or by
         any other method of allocation which does not take account of the
         equitable considerations referred to above. Notwithstanding the
         provisions of this Section 9, no Underwriter shall be required to
         contribute in excess of the amount equal to the excess of (i) the total
         price at which the Securities underwritten by it were offered to the
         public, over (ii) the amount of any damages which such Underwriter has
         otherwise been required to pay by reason of any such untrue or alleged
         untrue statement or omission or alleged omission. The obligations of
         each Underwriter to contribute pursuant to this Section 9 are several
         and not joint and shall be in proportion to the principal amount of
         Securities set forth opposite its name in Schedule II hereto.

                  10. Termination. This Agreement may be terminated, at any time
                      -----------
prior to the Closing Date, by the Representatives by written notice to the
Company if (a) after the date hereof and at or prior to the Closing Date there
shall have occurred any suspension or material limitation of trading of any of
the Company's securities on the New York Stock Exchange, Inc. ("NYSE") or any
general suspension of trading in securities on the NYSE, the American Stock
Exchange, Inc. ("AMEX") or the NASDAQ Stock Market, Inc. ("NASDAQ") or there
shall have been established by the NYSE, AMEX or NASDAQ or by the Commission or
by any federal or state agency or by the decision of any court, any general
limitation on prices for such trading or any general restrictions on the
distribution of securities, or a general banking moratorium declared by New York
or federal authorities, or (b) there shall have occurred any (i) new material
outbreak of hostilities or (ii) new material other national or international
calamity or crisis, including, but not limited to, an escalation of hostilities
that existed prior to the date of this Agreement or (iii) material adverse
change in the financial markets in the United States, and the effect of any such
event specified in clause (a) or (b) above on the financial markets of the
United States shall be such as to make it impracticable, in the reasonable
judgment of the Representatives, for the Underwriters to enforce contracts for
the sale of the Securities. This Agreement may also be terminated at any time
prior to the Closing Date by the Representatives if, in their reasonable
judgment, the subject matter of any amendment or supplement to the Registration
Statement or the Prospectus (other than an amendment or supplement relating
solely to the activity of any Underwriter or Underwriters) prepared and issued
by the Company after the effectiveness of this Agreement shall have disclosed a
material adverse change in the business, property or financial condition of the
Company that has materially impaired the marketability of the Securities. Any
termination hereof pursuant to this Section 10 shall be without liability of any
party to any other party except as otherwise provided in Sections 6(g) and 9
hereof.

                   11. Miscellaneous. THE VALIDITY AND INTERPRETATION OF THIS
                       -------------
AGREEMENT SHALL BE GOVERNED BY THE LAWS OF THE STATE OF NEW YORK. This Agreement
shall inure to the benefit of the Company, the several Underwriters and, with
respect to the provisions of Section 9 hereof, each director, officer and
controlling person referred to in said Section 9, and their respective
successors. Nothing herein is intended or shall be construed to give to any
other person, firm or corporation any legal or equitable right, remedy or claim
under or in respect of any provision in this Agreement. The term "successor" as
used herein shall not include any purchaser, as such purchaser, of any of the
Securities from any of the several Underwriters.

                   12.     Notices.  All communications hereunder shall be in

as Representatives of the Underwriters named in Schedule II
to the Underwriting Agreement, as herein defined

c/o



Ladies and Gentlemen:

                  We have acted as General Counsel to TXU Gas Company, a Texas
corporation, (the "Company"), in connection with the issuance and sale by the
Company of      of its               ("Securities") pursuant to the Underwriting
           ----        -------------
Agreement dated                among the Company and you (the "Underwriting
                --------------
Agreement").

                  Terms not otherwise defined herein are used with the meanings
ascribed to them in the Underwriting Agreement.

                  In so acting we have participated in or reviewed the corporate
proceedings in connection with the authorization, execution and delivery of the
Underwriting Agreement, the Indenture, and the Securities. We have also examined
such other documents and satisfied ourselves as to such other matters as we have
deemed necessary as a basis for the conclusions of law contained in the opinions
expressed below. We have relied as to various questions of fact upon the
representations and warranties of the Company contained in the Underwriting
Agreement and, where we deemed appropriate, on certificates of public officials.
We have relied upon a certificate of the Indenture Trustee as to the
authentication of the Securities. In our examination we have assumed the
genuineness of all signatures and the authenticity of all documents submitted to
us as originals and the conformity to original documents of all documents
submitted to us as photostatic or certified copies.

                  Upon the basis of our familiarity with these transactions and
with the affairs and properties of the Company generally, we are of the opinion
that:

               1. The Company is a corporation duly authorized, validly existing
and in good standing under the laws of the State of Texas, and has the corporate
power and authority: (a) to execute, deliver and perform its obligations under
the Underwriting Agreement and the Indenture, (b) to issue the Securities and to
incur the indebtedness to be evidenced thereby and (c) to own its property and
assets and to conduct the business which it is now conducting.

               2. The Underwriting Agreement has been duly authorized, executed
and delivered by the Company.

               3. The Indenture has been duly qualified under the Trust
Indenture Act.

               4. The Securities and the Indenture have been duly authorized,
executed and delivered by the Company, the Securities are entitled to the
benefits of the Indenture, and the Securities and the Indenture are legal, valid
and binding obligations of the Company enforceable against the Company in
accordance with their respective terms, subject to the effect of bankruptcy,
insolvency, reorganization, fraudulent conveyance, receivership, moratorium and
other laws affecting the rights and remedies of creditors generally and of
general principles of equity.

               5. The statements made in the Prospectus under the captions
[Insert titles of sections describing the Securities in the Prospectus and
Prospectus Supplement], insofar as they purport to constitute summaries of the
terms of the documents referred to therein, constitute accurate summaries of the
terms of such documents in all material respects.

               6. The Company is not an investment company within the meaning of
the Investment Company Act of 1940, as amended.

               7. Other than as stated in the Registration Statement and the
Prospectus, there are no material pending legal proceedings to which the Company
is a party or of which property of the Company is the subject which depart from
the ordinary routine litigation incident to the kind of business conducted by
the Company, and to our knowledge no such proceedings are contemplated.

               8. The Registration Statement, and the Prospectus at the time it
was filed with the Commission pursuant to Rule 424 under the Securities Act
(except for financial statements and schedules and other financial and
statistical data contained or incorporated by reference therein
and except for that part of the Registration Statement that constitutes
the Forms T-1, as to which we do not express any belief) complied as to form in
all material respects with the Securities Act and the applicable instructions,
rules and regulations of the Commission thereunder; the Incorporated Documents
(except as to the financial statements and schedules and other financial and
statistical data contained therein, as to which we do not express any opinion),
at the time they were filed with the Commission, complied as to form in all
material respects with the requirements of the Exchange Act and the applicable
instructions, rules and regulations of the Commission thereunder; and the
Registration Statement has become and is effective under the Securities Act and,
to our best knowledge, no proceedings for a stop order with respect thereto are
pending or threatened under Section 8 of the Securities Act.

               9. No other approval, authorization, consent or order of any
public board or body (other than in connection or in compliance with the
provisions of the blue-sky laws of any jurisdiction) is legally required for the
authorization of the issue and sale by the Company of the Securities.

               In the course of the preparation of the information relating to
the Company contained in the Prospectus (including the documents incorporated
therein by reference) we had discussions with certain of its officers and
representatives and certain officers and representatives of certain of its
subsidiaries, with other counsel for the Company, with Deloitte & Touche LLP,
the Company's independent certified public accountants who audited certain of
the financial statements contained in documents incorporated by reference in the
Registration Statement and the Prospectus, and with certain of your officers and
employees and your counsel, but we made no independent verification of the
accuracy or completeness of the representations and statements made to us by the
Company or the information included by the Company in the Prospectus and take no
responsibility therefor except as set forth in paragraph 5 above. However, our
examination of the information relating to the Company contained in the
Registration Statement and the Prospectus and our discussions did not disclose
to us anything which gives us reason to believe that (except as to financial
statements and schedules and other financial and statistical data and except as
to that part of the Registration Statement that constitutes the Forms T-1, as to
which we do not express any belief) (i) the Registration Statement, as of the
Effective Date, included an untrue statement of a material fact or omitted to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading or (ii) the Prospectus at the time it was
filed with the Commission pursuant to Rule 424, included, or on the date hereof
includes an untrue statement of a material fact or on such dates omitted or
omits to state a material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading.

               We are members of the State Bar of Texas and do not hold
ourselves out as experts in the laws of the State of New York. As to all matters
of New York law, we have, with your consent, relied upon the opinion of even
date herewith of Thelen Reid & Priest LLP, New York, New York, of Counsel to the
Company.

                                         Very truly yours,

                                         WORSHAM, FORSYTHE &
                                          WOOLDRIDGE, L.L.P.

Ladies and Gentlemen:

                  We have acted as counsel to TXU Gas Company, a Texas

Company of      of its               ("Securities") pursuant to the Underwriting

of the Investment Company Act of 1940, as amended.

                  6. The Registration Statement, and the Prospectus at the time
it was filed with the Commission pursuant to Rule 424 under the Securities Act

Agreement as defined herein

c/o


Ladies and Gentlemen:

                  We have acted as counsel to you and the several Underwriters
in connection with the issuance and sale by the TXU Gas Company, a Texas
corporation (the "Company"), of      of its               ("Securities")
                                ----        -------------
pursuant to the Underwriting Agreement dated                among the Company
                                             --------------
and you (the "Underwriting Agreement").

                  Terms not otherwise defined herein are used with the meanings
ascribed to them in the Underwriting Agreement.

                  We are members of the New York Bar and do not hold ourselves
out as experts on the laws of the State of Texas. We have, with your consent,
relied upon an opinion of even date herewith addressed to you by Worsham,
Forsythe & Wooldridge, L.L.P., Dallas, Texas, General Counsel for the Company,
as to the matters covered in such opinion relating to Texas law. We have
reviewed such opinion and believe that it is satisfactory and that you and we
are justified in relying thereon.

                  We have, in addition, examined the documents described in the
list of closing papers as having been delivered to you at the closing and such
other documents and satisfied ourselves as to such other matters as we have
deemed necessary in order to enable us to express this opinion. As to various
questions of fact material to this opinion, we have relied upon representations
of the Company and statements in the Registration Statement hereinafter
mentioned. In such examination we have assumed the genuineness of all
signatures, the authenticity of all documents submitted to us and the
genuineness and conformity to original documents of documents submitted to us
as certified or photostatic copies.

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

                  1. The Underwriting Agreement has been duly authorized,
executed and delivered by the Company.

                  2. The Securities and the Indenture have been duly authorized,
executed and delivered by the Company, the Securities are entitled to the
benefits of the Indenture, and the Securities and the Indenture are legal, valid
and binding obligations of the Company enforceable against the Company in
accordance with their respective terms, subject to the effect of bankruptcy,
insolvency, reorganization, fraudulent conveyance, receivership, moratorium and
other laws affecting the rights and remedies of creditors generally and of
general principles of equity.

                  3. The statements made in the Prospectus under the captions
[Insert titles of sections describing the Securities in the Prospectus and
Prospectus Supplement], insofar as they purport to constitute summaries of the
terms of the documents referred to therein, constitute accurate summaries of the
terms of such documents in all material respects.

                  4. No other approval, authorization, consent or order of any
public board or body (other than in connection or in compliance with the
blue-sky laws of any jurisdiction) is legally required for the authorization of
the issue and sale by the Company of the Securities.

                  5. The Registration Statement, and the Prospectus at the time
it was filed with the Commission pursuant to Rule 424 under the Securities Act
(except for financial statements and schedules and other financial and
statistical data contained or incorporated by reference therein and except for
that part of the Registration Statement that constitutes the Forms T-1, as to
which we do not express any belief) complied as to form in all material respects
with the Securities Act and the applicable instructions, rules and regulations
of the Commission thereunder.


                  In passing upon the form of the Registration Statement and the
form of the Prospectus, we necessarily assume the correctness and completeness
of the statements made by the Company and the information included in the
Registration Statement and the Prospectus and take no responsibility therefor,
except insofar as such statements relate to us and as set forth in paragraph 3
above. In the course of the preparation by the Company of the Registration
Statement and the Prospectus, we have had discussions with certain of the
Company's officers and representatives, and representatives of certain of its
subsidiaries, with counsel for the Company, with Deloitte & Touche LLP, the
Company's independent public accountants who audited certain of the financial
statements incorporated by reference in the Registration Statement and the
Prospectus, and with certain of your representatives. Our examination of the
Registration Statement and the Prospectus and our discussions did not disclose
to us any information which gives us reason to believe that at the Effective
Date the Registration Statement contained an untrue statement of a material fact
or omitted to state a material fact required to be stated therein or necessary
to make the statements therein not misleading or that the Prospectus, at the
time it was filed with the Commission pursuant to Rule 424, or at the date
hereof, included or includes an untrue statement of a material fact or omitted
or omits to state a material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading. We do not express any opinion or belief as to the financial
statements and schedules or other financial or statistical data contained or
incorporated by reference in the Registration Statement or Prospectus or as to
that part of the Registration Statement that constitutes the Forms T-1.

                  This opinion is given to you solely for the use of the several
Underwriters in connection with the Underwriting Agreement and the transactions
contemplated thereunder and may not be relied upon by any other person or for
any other purpose.

          4.   Purchase and Sale.
               -----------------

          (a)  On the basis of the representations and warranties herein
     contained, and subject to the terms and conditions herein set forth, the
     Trust shall sell to each of the Underwriters, and each Underwriter shall
     purchase from the Trust, at the time and place herein specified, severally
     and not jointly, the liquidation preference amount of the Preferred Trust
     Securities set forth opposite the name of such Underwriter in Schedule II
     attached hereto, at the purchase price or prices set forth in Schedule I
     hereto.

          (b)  The Company shall pay to the Underwriters a commission
     equal to      % of the aggregate liquidation preference amount of the
              -----
     Preferred Trust Securities.

          5.   Time and Place of Closing. Delivery of the Preferred Trust
               -------------------------
Securities against payment of the aggregate purchase price therefor by wire
transfer in federal funds shall be made at the offices of Thelen Reid & Priest
LLP, 40 West 57th Street, New York, New York, at 10:00 A.M., New York Time, on
                   , or at such other place, time and date as shall be agreed
- -------------------

following paragraph. The hour and date of such delivery and payment are herein


                                       -4-


<PAGE>


called the "Closing Date". The Preferred Trust Securities shall be delivered to
The Depository Trust Company or to The Bank of New York, as custodian for The
Depository Trust Company, in fully registered global form registered in the name
of Cede & Co., for the respective accounts specified by you not later than the
close of business on the business day preceding the Closing Date. The Trust
agrees to make the Preferred Trust Securities available to you for checking
purposes not later than 10:00 A.M., New York Time, on the last business day
preceding the Closing Date at the offices of Thelen Reid & Priest, 40 West
57th Street, New York, New York, 10019, or at such other place as the Trust may
specify.

          If any Underwriter shall fail or refuse (otherwise than for some
reason sufficient to justify, in accordance with the terms hereof, the
cancellation or termination of its obligations hereunder) to purchase and pay
for the liquidation preference amount of the Preferred Trust Securities that
such Underwriter has agreed to purchase and pay for hereunder, the Company shall
immediately give notice to the other Underwriters of the default of such
Underwriter, and the other Underwriters shall have the right within 24 hours
after the receipt of such notice to determine to purchase, or to procure one or
more others, who are members of the National Association of Securities Dealers,
Inc. ("NASD") (or, if not members of the NASD, who are not eligible for
membership in the NASD and who agree (i) to make no sales within the United
States, its territories or its possessions or to persons who are citizens
thereof or residents therein and (ii) in making sales to comply with the NASD's
Conduct Rules) and satisfactory to the Company, to purchase, upon the terms
herein set forth, the liquidation preference amount of the Preferred Trust
Securities that the defaulting Underwriter had agreed to purchase. If any
non-defaulting Underwriter or Underwriters shall determine to exercise such
right, such Underwriter or Underwriters shall give written notice to the Company
of the determination in that regard within 24 hours after receipt of notice of
any such default, and thereupon the Closing Date shall be postponed for such
period, not exceeding three business days, as the Company shall determine. If in
the event of such a default no non-defaulting Underwriter shall give such
notice, then this Agreement may be terminated by the Company, upon like notice
given to the non-defaulting Underwriters, within a further period of 24 hours.
If in such case the Company shall not elect to terminate this Agreement it shall
have the right, irrespective of such default:

          (a)  to require each non-defaulting Underwriter to purchase and
     pay for the respective liquidation preference amount of the Preferred Trust
     Securities that it had agreed to purchase hereunder as hereinabove provided
     and, in addition, the liquidation preference amount of the Preferred Trust
     Securities that the defaulting Underwriter shall have so failed to purchase


                                       -5-


<PAGE>


     up to a liquidation preference amount thereof equal to one-ninth (1/9) of
     the liquidation preference amount of Preferred Trust Securities that such
     non-defaulting Underwriter has otherwise agreed to purchase hereunder,
     and/or

          (b)  to procure one or more persons, reasonably acceptable to
     the Representatives, who are members of the NASD (or, if not members of the
     NASD, who are not eligible for membership in the NASD and who agree (i) to
     make no sales within the United States, its territories or its possessions
     or to persons who are citizens thereof or residents therein and (ii) in
     making sales to comply with the NASD's Conduct Rules), to purchase, upon
     the terms herein set forth, either all or a part of the liquidation
     preference amount of the Preferred Trust Securities that such defaulting
     Underwriter had agreed to purchase or that portion thereof that the
     remaining Underwriters shall not be obligated to purchase pursuant to the
     foregoing clause (a).

In the event the Company shall exercise its rights under (a) and/or (b) above,
the Company shall give written notice thereof to the non-defaulting Underwriters
within such further period of 24 hours, and thereupon the Closing Date shall be
postponed for such period, not exceeding three business days, as the Company
shall determine.

          In the computation of any period of 24 hours referred to in this
Section 5, there shall be excluded a period of 24 hours in respect of each
Saturday, Sunday or legal holiday that would otherwise be included in such
period of time.

          Any action taken by the Company under this Section 5 shall not relieve
any defaulting Underwriter from liability in respect of any default of such
Underwriter under this Agreement. Termination by the Company under this Section
5 shall be without any liability on the part of the Company or any
non-defaulting Underwriter, except as otherwise provided in Sections 6(g) and 9
hereof.

          6.   Covenants of the Company. The Company agrees that:
               ------------------------

          (a) It will promptly deliver to each of you a signed copy of the
     Registration Statement as originally filed or, to the extent a signed copy
     is not available, a conformed copy, certified by an officer of the Company
     to be in the form as originally filed, including all Incorporated Documents
     and exhibits and of all amendments thereto.

          (b)  It will deliver to you, as soon as practicable after the
     date hereof, as many copies of the Prospectus as of such date as you may
     reasonably request.

                                       -6-


<PAGE>


          (c)  It will cause the Prospectus to be filed with the Commission
     pursuant to Rule 424 as soon as practicable and advise you of the issuance
     of any stop order under the Securities Act with respect to the Registration
     Statement or the institution of any proceedings therefor of which the
     Offerors shall have received notice. The Company will use its best efforts
     to prevent the issuance of any such stop order and to secure the prompt
     removal thereof if issued.

          (d)  If, during such period of time (not exceeding nine months) after
     the Prospectus has been filed with the Commission pursuant to Rule 424 as
     in the opinion of Counsel for the Underwriters a prospectus covering the
     Preferred Trust Securities is required by law to be delivered in connection
     with sales by an Underwriter or dealer, any event relating to or affecting
     the Company or the Trust or of which the Company shall be advised in
     writing by you shall occur that in the Company's reasonable opinion after
     consultation with Counsel for the Underwriters should be set forth in a
     supplement to, or an amendment of, the Prospectus in order to make the
     Prospectus not misleading in the light of the circumstances when it is
     delivered to a purchaser, the Company will, at its expense, amend or
     supplement the Prospectus by either (i) preparing and furnishing to you at
     the Company's expense a reasonable number of copies of a supplement or
     supplements or an amendment or amendments to the Prospectus or (ii) making
     an appropriate filing pursuant to Section 13 of the Exchange Act, which
     will supplement or amend the Prospectus so that, as supplemented or
     amended, it will not contain any untrue statement of a material fact or
     omit to state any material fact necessary in order to make the statements
     therein, in the light of the circumstances when the Prospectus is delivered
     to a purchaser, not misleading; provided that should such event relate
     solely to the activities of any of the Underwriters, then the Underwriters
     shall assume the expense of preparing and furnishing any such amendment or
     supplement. In case any Underwriter is required to deliver a prospectus
     after the expiration of nine months from the date the Prospectus is filed
     with the Commission pursuant to Rule 424, the Company, upon such
     Underwriter's request, will furnish to such Underwriter, at the expense of
     such Underwriter, a reasonable quantity of a supplemental prospectus or
     supplements to the Prospectus complying with Section 10(a) of the
     Securities Act.

          (e)  It will make generally available to its security holders and the
     security holders of the Trust, as soon as practicable, an earnings
     statement (which need not be audited) covering a period of at least twelve
     months beginning not earlier than the first day of the month next


                                       -7-


<PAGE>


     succeeding the month in which occurred the effective date of the
     the Registration Statement as defined in Rule 158 under the Securities Act.

          (f)  It will furnish such proper information as may be lawfully
     required and otherwise cooperate in qualifying the Preferred Trust
     Securities for offer and sale under the blue-sky laws of such jurisdictions
     as you may designate, provided that the neither of the Offerors shall be
     required to qualify as a foreign corporation or dealer in securities, to
     file any consents to service of process under the laws of any jurisdiction,
     or to meet any other requirements deemed by the Offerors to be unduly
     burdensome.

          (g) It will, except as herein provided, pay all expenses and taxes
     (except transfer taxes) in connection with (i) the preparation and filing
     by it of the Registration Statement, (ii) the issuance and delivery of the
     Preferred Trust Securities as provided in Section 5 hereof, (iii) the
     qualification of the Preferred Trust Securities under blue-sky laws
     (including counsel fees not to exceed $7,500), and (iv) the printing and
     delivery to the Underwriters of reasonable quantities of the Registration
     Statement and, except as provided in Section 6(d) hereof, of the
     Prospectus. The Company shall not, however, be required to pay any amount
     for any expenses of yours or any of the Underwriters, except that, if this
     Agreement shall be terminated in accordance with the provisions of
     Section 7, 8 or 10 hereof, the Company will reimburse you for the fees and
     disbursements of Counsel for the Underwriters, whose fees and disbursements
     the Underwriters agree to pay in any other event, and will reimburse the
     Underwriters for their reasonable out-of-pocket expenses, in an aggregate
     amount not exceeding $5,000, incurred in contemplation of the performance
     of this Agreement. The Company shall not in any event be liable to any of
     the several Underwriters for damages on account of loss of anticipated
     profits.

          (h)  During the period from the date of this Agreement to the
     Closing Date, neither the Company nor the Trust will, without the prior
     written consent of the Representatives, directly or indirectly, publicly
     issue, sell, offer or contract to sell, in the market in which the
     Preferred Trust Securities are being offered and sold, any securities of
     the Company or any of its subsidiaries or of the Trust which are of the
     same class as the Preferred Trust Securities.

          7.   Conditions of Underwriters' Obligations. The obligations of the
               ---------------------------------------
Underwriters to purchase and pay for the Preferred Trust Securities shall be
subject to the accuracy of the representations and warranties made herein on the
part of each of the Offerors, to the performance by each of the Offerors

                                       -8-


<PAGE>


of its obligations to be performed hereunder prior to the Closing Date, and to
the following conditions:

          (a)  The Prospectus shall have been filed with the Commission
     pursuant to Rule 424 prior to 5:30 P.M., New York Time, on the second
     business day after the date of this Agreement, or such other time and date
     as may be approved by you.

          (b)  No stop order suspending the effectiveness of the Registration
     Statement shall be in effect, and no proceedings for that purpose shall be
     pending before, or threatened by, the Commission on the Closing Date; and
     you shall have received a certificate, dated the Closing Date and signed by
     an officer of the Company, to the effect that no such stop order is in
     effect and that no proceedings for such purpose are pending before, or to
     the knowledge of the Company threatened by, the Commission.

          (c)  On the Closing Date, you shall have received from Richards,
     Layton & Finger, P.A., Delaware counsel for the Company and the Trust,
     Worsham, Forsythe & Wooldridge, L.L.P., General Counsel for the Company,
     Thelen Reid & Priest LLP, of counsel for the Company, and Winthrop,
     Stimson, Putnam & Roberts, Counsel for the Underwriters, opinions in
     substantially the form and substance prescribed in Schedules III, IV, V and
     VI hereto (i) with such changes therein as may be agreed upon by the
     Company and you, with the approval of Counsel for the Underwriters, and
     (ii) if the Prospectus relating to the Preferred Trust Securities shall be
     supplemented or amended after the Prospectus shall have been filed with the
     Commission pursuant to Rule 424, with any changes therein necessary to
     reflect such supplementation or amendment.

          (d)  On and as of the Closing Date, you shall have received from
     Deloitte & Touche LLP a letter to the effect that (i) they are independent
     certified public accountants with respect to the Company, within the
     meaning of the Securities Act and the applicable published rules and
     regulations thereunder, (ii) in their opinion, the financial statements
     audited by them and included or incorporated by reference in the Prospectus
     comply as to form in all material respects with the applicable accounting
     requirements of the Exchange Act and the applicable published rules and
     regulations thereunder, (iii) on the basis of a reading of the unaudited
     amounts of operating revenues and net income included or incorporated by
     reference in the Prospectus and the related financial statements from which
     these amounts were derived, the latest available unaudited financial
     statements of the Company and the minute books of the Company and inquiries

                                       -9-


<PAGE>



     of officers of the Company and of certain direct and indirect subsidiaries
     of the Company who have responsibility for financial and accounting matters
     (it being understood that the foregoing procedures do not constitute an
     audit made in accordance with generally accepted auditing standards and
     would not necessarily reveal matters of significance with respect to the
     comments made in such letter, and accordingly that Deloitte & Touche LLP
     makes no representation as to the sufficiency of such procedures for the
     several Underwriters' purposes), nothing has come to their attention which
     caused them to believe that (A) the unaudited financial statements of the
     Company incorporated by reference in the Prospectus were not determined in
     accordance with generally accepted accounting principles applied on a basis
     substantially consistent with that of the corresponding amounts in the
     latest available audited financial statements of the Company, (B) the
     unaudited amounts of operating revenues and net income of the Company
     included or incorporated by reference in the Prospectus were not determined
     on a basis substantially consistent with that of the corresponding amounts
     in the audited statements of income of the Company, incorporated by
     reference in the Prospectus, (C) for the twelve months ended
                        , if available, there were any decreases in operating
     -------------------
     revenues or net income as compared with the comparable period of the
     preceding year, and (D) at a specified date not more than seven days prior
     to the date of such letter, there was any change in the capital stock of
     the Company, short-term bank loans, commercial paper, notes payable to TXU
     Corp or long-term debt of the Company or decrease in its net assets, in
     each case as compared with amounts shown in the most recent balance sheets
     of the Company incorporated by reference in the Prospectus, except in all
     instances for changes or decreases that the Prospectus discloses have
     occurred or may occur or which are occasioned by the declaration of a
     regular quarterly dividend or the acquisition of long-term debt for sinking
     fund purposes, or which are described in such letter, and (iv) they have
     compared the dollar amounts (or percentages or ratios derived from such
     dollar amounts) and other financial information included or incorporated by
     reference in the Registration Statement and the Prospectus as reasonably
     requested by you (in each case to the extent that such dollar amounts,
     percentages and other financial information are derived from the general
     accounting records of the Company and its consolidated subsidiaries subject
     to the internal controls of the accounting system of such companies or are
     derived indirectly from such records by analysis or computation) with the
     results obtained from inquiries, a reading of such general accounting
     records and other procedures specified in such letter, and have found such

                                      -10-


<PAGE>



     dollar amounts, percentages and other financial information to be in
     agreement with such results, except as otherwise specified in such letter.

          (e)  Since the most recent dates as of which information is
     given in the Registration Statement or the Prospectus there shall not have
     been any material adverse change in the business, property or financial
     condition of the Company and its subsidiaries, considered as a whole, and,
     since such dates, there shall not have been any material transaction
     entered into by the Company and its subsidiaries, in each case other than
     transactions in the ordinary course of business and transactions
     contemplated by the Registration Statement or Prospectus, and at the
     Closing Date you shall have received a certificate to such effect dated the
     Closing Date and signed by an officer of the Company.

          (f)  All legal proceedings to be taken in connection with the issuance
     and sale of the Preferred Trust Securities, the Debentures, the Guarantee,
     and the common trust securities to be issued by the Trust as described in
     the Prospectus shall have been satisfactory in form and substance to
     Counsel for the Underwriters.

          (g)  Since the date of this agreement, neither Moody's Investor
     Services nor Standard and Poor's Corporation shall have downgraded or
     publicly announced that it has under surveillance or review, with possible
     negative implications, its rating of any securities of the Company which
     are of the same class as the Preferred Trust Securities or the financial
     condition of the Company.

          In case any of the conditions specified above in this Section 7 shall
not have been fulfilled, this Agreement may be terminated by the Representatives
upon notice thereof to the Company. Any such termination shall be without
liability of any party to any other party except as otherwise provided in
Sections 6(g) and 9 hereof.

          8.   Conditions of Offerors' Obligations. The obligation of the
               -----------------------------------
Offerors to deliver the Preferred Trust Securities shall be subject to the
conditions that the Prospectus shall have been filed with the Commission
pursuant to Rule 424 prior to 5:30 P.M., New York Time, on the second business
day after the date of this Agreement or such other time and date as may be
approved by the Company, and no stop order suspending the effectiveness of the
Registration Statement shall be in effect at the Closing Date and no proceedings
for that purpose shall be pending before, or threatened by, the Commission at
the Closing Date. In case these conditions shall not have been fulfilled, this
Agreement may be terminated by the Company upon notice thereof to you. Any such

                                      -11-


<PAGE>


termination shall be without liability of any party to any other party except as
otherwise provided in Sections 6(g) and 9 hereof.

          9.   Indemnification.
               ---------------

          (a)  The Offerors shall jointly and severally indemnify, defend and
     hold harmless each Underwriter and each person who controls any Underwriter
     within the meaning of Section 15 of the Securities Act from and against any
     and all losses, claims, damages or liabilities, joint or several, to which
     they or any of them may become subject under the Securities Act or any
     other statute or common law and shall reimburse each such Underwriter and
     controlling person for any legal or other expenses (including, to the
     extent hereinafter provided, reasonable counsel fees) incurred by them in
     connection with investigating any such losses, claims, damages or
     liabilities or in connection with defending any actions, insofar as such
     losses, claims, damages, liabilities, expenses or actions arise out of or
     are based upon any untrue statement or alleged untrue statement of a
     material fact contained in the Registration Statement or the Prospectus (or
     any amendment or supplement thereto), or the omission or alleged omission
     to state therein a material fact required to be stated therein or necessary
     to make the statements therein in the light of the circumstances under
     which they were made not misleading; provided, however, that the indemnity
     agreement contained in this Section 9 shall not apply to any such losses,
     claims, damages, liabilities, expenses or actions arising out of, or based
     upon, any such untrue statement or alleged untrue statement, or any such
     omission or alleged omission, if such statement or omission was made in
     reliance upon information furnished in writing to the Offerors by or on
     behalf of any Underwriter, for use in connection with the preparation of
     the Registration Statement or the Prospectus or any amendment or supplement
     to either thereof, or arising out of, or based upon, statements in or
     omissions from that part of the Registration Statement that shall
     constitute the Statements of Eligibility and Qualification under the Trust
     Indenture Act of any Trustee with respect to any indenture qualified
     pursuant to the Registration Statement; and provided further, that the
     indemnity agreement contained in this Section 9 shall not inure to the
     benefit of any Underwriter (or of any person controlling such Underwriter)
     on account of any such losses, claims, damages, liabilities, expenses or
     actions arising from the sale of the Preferred Trust Securities to any
     person if a copy of the Prospectus (including any amendment or supplement
     thereto if any amendments or supplements thereto shall have been furnished
     to the Underwriters at or prior to the time of written confirmation of the
     sale involved and such amendment or supplement corrected the alleged

                                      -12-


<PAGE>


     omission or alleged untrue statement in the Prospectus) (exclusive of the
     Incorporated Documents) shall not have been given or sent to such person by
     or on behalf of such Underwriter with or prior to the written confirmation
     of the sale involved. The indemnity agreement of the Offerors contained in
     this Section 9 and the representations and warranties of the Offerors
     contained in Section 3 hereof shall remain operative and in full force and
     effect regardless of any termination of this Agreement or of any
     investigation made by or on behalf of any Underwriter or any such
     controlling person, and shall survive the delivery of the Preferred Trust
     Securities.

          (b)  Each Underwriter shall indemnify, defend and hold harmless the
     Offerors, their officers and directors, and each person who controls either
     of the Offerors within the meaning of Section 15 of the Securities Act,
     from and against any and all losses, claims, damages or liabilities, joint
     or several, to which they or any of them may become subject under the
     Securities Act or any other statute or common law and shall reimburse each
     of them for any legal or other expenses (including, to the extent
     hereinafter provided, reasonable counsel fees) incurred by them in
     connection with investigating any such losses, claims, damages or
     liabilities or in connection with defending any actions, insofar as such
     losses, claims, damages, liabilities, expenses or actions arise out of or
     are based upon any untrue statement or alleged untrue statement of a
     material fact contained in the Registration Statement or the Prospectus (or
     any amendment or supplement thereto), or the omission or alleged omission
     to state therein a material fact required to be stated therein or necessary
     to make the statements therein not misleading, if such statement or
     omission was made in reliance upon and in conformity with information
     furnished in writing to the Offerors by or on behalf of such Underwriter,
     through the Representatives or Counsel for the Underwriters, for use in
     connection with the preparation of the Registration Statement or the
     Prospectus or any amendment or supplement to either thereof. Each
     Underwriter hereby furnishes to the Offerors in writing expressly for use
     in the Prospectus [indicate topics addressed and location in the
     Prospectus]. The indemnity agreement of the respective Underwriters
     contained in this Section 9 shall remain operative and in full force and
     effect regardless of any termination of this Agreement or of any
     investigation made by or on behalf of either Offeror, its directors or its
     officers, any such Underwriter, or any such controlling person, and shall
     survive the delivery of the Preferred Trust Securities.

          (c)  The Company, the Trust and the several Underwriters each shall,
     upon the receipt of notice of the commencement of any action against it or


                                      -13-


<PAGE>


     any person controlling it as aforesaid, in respect of which indemnity may
     be sought on account of any indemnity agreement contained herein, promptly
     give written notice of the commencement thereof to the party or parties
     against whom indemnity shall be sought hereunder, but the omission so to
     notify such indemnifying party or parties of any such action shall not
     relieve such indemnifying party or parties from any liability which it or
     they may have to the indemnified party otherwise than on account of such
     indemnity agreement. In case such notice of any such action shall be so
     given, such indemnifying party shall be entitled to participate at its own
     expense in the defense, or, if it so elects, to assume (in conjunction with
     any other indemnifying parties) the defense of such action, in which event
     such defense shall be conducted by counsel chosen by such indemnifying
     party or parties and satisfactory to the indemnified party or parties who
     shall be defendant or defendants in such action, and such defendant or
     defendants shall bear the fees and expenses of any additional counsel
     retained by them; but if the indemnifying party shall elect not to assume
     the defense of such action, such indemnifying party will reimburse such
     indemnified party or parties for the reasonable fees and expenses of any
     counsel retained by them; provided, however, if the defendants in any such
     action include both the indemnified party and the indemnifying party and
     counsel for the indemnifying party shall have reasonably concluded that
     there may be a conflict of interest involved in the representation by such
     counsel of both the indemnifying party and the indemnified party, the
     indemnified party or parties shall have the right to select separate
     counsel, satisfactory to the indemnifying party, to participate in the
     defense of such action on behalf of such indemnified party or parties (it
     being understood, however, that the indemnifying party shall not be liable
     for the expenses of more than one separate counsel representing the
     indemnified parties who are parties to such action). Each of the Company
     and the Underwriters agrees that without the other party's prior written
     consent, which consent shall not be unreasonably withheld, it will not
     settle, compromise or consent to the entry of any judgment in any claim in
     respect of which indemnification may be sought under the indemnification
     provisions of this Agreement, unless such settlement, compromise or consent
     (i) includes an unconditional release of such other party from all
     liability arising out of such claim and (ii) does not include a statement
     as to or an admission of fault, culpability or a failure to act by or on
     behalf of such other party.

          (d)  If the indemnification provided for in subparagraph (a) or (b)
     above shall be unenforceable under applicable law by an indemnified party,

                                      -14-


<PAGE>



     each indemnifying party agrees to contribute to such indemnified party with
     respect to any and all losses, claims, damages, liabilities and expenses
     for which each such indemnification provided for in subparagraph (a) or (b)
     above shall be unenforceable, in such proportion as shall be appropriate to
     reflect (i) the relative fault of each indemnifying party on the one hand
     and the indemnified party on the other in connection with the statements or
     omissions which have resulted in such losses, claims, damages, liabilities
     and expenses, (ii) the relative benefits received by the Offerors on the
     one hand and the Underwriters on the other hand from the offering of the
     Preferred Trust Securities pursuant to this Agreement, and (iii) any other
     relevant equitable considerations; provided, however, that no indemnified
     party guilty of fraudulent misrepresentation (within the meaning of
     Section 11(f) of the Securities Act) shall be entitled to contribution from
     any indemnifying party not guilty of such fraudulent misrepresentation.
     Relative fault shall be determined by reference to, among other things,
     whether the untrue or alleged untrue statement of a material fact or the
     omission or alleged omission to state a material fact relates to
     information supplied by such indemnifying party or the indemnified party
     and each such party's relative intent, knowledge, access to information and
     opportunity to correct or prevent such untrue statement or omission. The
     Offerors and each of the Underwriters agree that it would not be just and
     equitable if contributions pursuant to this subparagraph (d) were to be
     determined by pro rata allocation (even if the Underwriters were treated as
     one entity for such purpose) or by any other method of allocation which
     does not take account of the equitable considerations referred to above.
     Notwithstanding the provisions of this Section 9, no Underwriter shall be
     required to contribute in excess of the amount equal to the excess of
     (i) the total price at which the Preferred Trust Securities underwritten by
     it were offered to the public, over (ii) the amount of any damages which
     such Underwriter has otherwise been required to pay by reason of any such
     untrue or alleged untrue statement or omission or alleged omission. The
     obligations of each Underwriter to contribute pursuant to this Section 9
     are several and not joint and shall be in proportion to the principal
     amount of Preferred Trust Securities set forth opposite its name in
     Schedule II hereto.

          10.  Termination. This Agreement may be terminated, at any time prior
               -----------
to the Closing Date, by the Representatives by written notice to the Company if
(a) after the date hereof and at or prior to the Closing Date there shall have
occurred any suspension or material limitation of trading of any of the
Company's securities on the New York Stock Exchange, Inc. ("NYSE") or any

                                      -15-


<PAGE>


general suspension of trading in securities on the NYSE, the American Stock
Exchange, Inc. ("AMEX") or the NASDAQ Stock Market, Inc. ("NASDAQ") or there
shall have been established by the NYSE, AMEX or NASDAQ or by the Commission or
by any federal or state agency or by the decision of any court, any general
limitation on prices for such trading or any general restrictions on the
distribution of securities, or a general banking moratorium declared by New York
or federal authorities, or (b) there shall have occurred any (i) new material
outbreak of hostilities or (ii) new material other national or international
calamity or crisis, including, but not limited to, an escalation of hostilities
that existed prior to the date of this Agreement or (iii) material adverse
change in the financial markets in the United States, and the effect of any such
event specified in clause (a) or (b) above on the financial markets of the
United States shall be such as to make it impracticable, in the reasonable
judgment of the Representatives, for the Underwriters to enforce contracts for
the sale of the Preferred Trust Securities. This Agreement may also be
terminated at any time prior to the Closing Date by the Representatives if, in
their reasonable judgment, the subject matter of any amendment or supplement to
the Registration Statement or the Prospectus (other than an amendment or
supplement relating solely to the activity of any Underwriter or Underwriters)
prepared and issued by the Company after the effectiveness of this Agreement
shall have disclosed a material adverse change in the business, property or
financial condition of the Company that has materially impaired the
marketability of the Preferred Trust Securities. Any termination hereof pursuant
to this Section 10 shall be without liability of any party to any other party
except as otherwise provided in Sections 6(g) and 9 hereof.

          11.  Miscellaneous. THE VALIDITY AND INTERPRETATION OF THIS AGREEMENT
               -------------
SHALL BE GOVERNED BY THE LAWS OF THE STATE OF NEW YORK. This Agreement shall
inure to the benefit of the Company, the several Underwriters and, with respect
to the provisions of Section 9 hereof, each director, officer and controlling
person referred to in said Section 9, and their respective successors. Nothing
herein is intended or shall be construed to give to any other person, firm or
corporation any legal or equitable right, remedy or claim under or in respect of
any provision in this Agreement. The term "successor" as used herein shall not
include any purchaser, as such purchaser, of any of the Preferred Trust
Securities from any of the several Underwriters.

          Re:  [Name of Trust]
               ---------------

Ladies and Gentlemen:

          We have acted as special Delaware counsel for TXU Gas Company, a Texas
corporation (the "Company"), and [Name of Trust], a Delaware business trust (the
"Trust"), in connection with the matters set forth herein. At your request, this
opinion is being furnished to you.

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

1999, by and among the Company and the trustees of the Trust named therein;

          (c) The Prospectus, dated           _, 1999, and the Prospectus
                                    -----------

Preferred Trust Securities of the Trust representing preferred undivided
beneficial interests in the assets of the Trust (each, a "Preferred Trust
Security" and collectively, the "Preferred Trust Securities");

          (d)  The Amended and Restated Trust Agreement of the Trust,
dated as of              ,        (including Exhibits A, B and D thereto) (the

(the "Trustees") and the holders, from time to time, of undivided beneficial
interests in the assets of the Trust;

named in Schedule II thereto; and

          (f) A Certificate of Good Standing for the Trust, dated             ,
                                                                  ------------
       , obtained from the Secretary of State.

          Initially capitalized terms used herein and not otherwise defined are
used as defined in the Trust Agreement.

          For purposes of this opinion, we have not reviewed any documents other
than the documents listed in paragraphs (a) through (f) above, which we believe
are all the documents necessary or appropriate for us to have considered for the
purposes of rendering the opinions stated herein. In particular, we have not
reviewed any document (other than the documents listed in paragraphs (a) through
(f) above) that is referred to in or incorporated by reference into the
documents reviewed by us. We have assumed that there exists no provision in any
document that we have not reviewed that is inconsistent with the opinions stated
herein. We have conducted no independent factual investigation of our own but
rather have relied solely upon the foregoing documents, the statements and
information set forth therein and the additional matters recited or assumed
herein, all of which we have assumed to be true, complete and accurate in all
material respects.

          With respect to all documents examined by us, we have assumed (i) the
authenticity of all documents submitted to us as authentic originals, (ii) the
conformity with the originals of all documents submitted to us as copies or
forms, and (iii) the genuineness of all signatures.

                  For purposes of this opinion, we have assumed (i) that the
Trust Agreement constitutes the entire agreement among the parties thereto with
respect to the subject matter thereof, including with respect to the creation,
operation and termination of the Trust, and that the Trust Agreement and the
Certificate are in full force and effect and have not been amended, (ii) except
to the extent provided in paragraph 1 below, the due creation, due formation


                                      III-2

<PAGE>


or due organization, as the case may be, and the valid existence in good
standing of each party to the documents examined by us under the laws of the
jurisdiction governing its creation, formation or organization, (iii) the legal
capacity of natural persons who are parties to the documents examined by us,
(iv) except to the extent set forth in paragraph 2 below, that each of the
parties to the documents examined by us has the power and authority to execute
and deliver, and to perform its obligations under, such documents, (v) except to
the extent provided in paragraph 4 below, that each of the parties to the
documents examined by us has duly authorized, executed and delivered such
documents, (vi) the receipt by each Person to whom a Preferred Trust Security is
to be issued by the Trust (the "Preferred Trust Security Holders") of a
Preferred Trust Securities Certificate for the Preferred Trust Security and the
payment for the Preferred Trust Security acquired by it, in accordance with the
Trust Agreement, and as described in the Prospectus, (vii) that the Preferred
Trust Securities are issued and sold to the Preferred Trust Security Holders in
accordance with the Trust Agreement, and as described in the Prospectus,
(viii) the receipt by the Person (the "Common Trust Security Holder") to whom a
Common Trust Security of the Trust representing common undivided beneficial
interests in the assets of the Trust (each, a "Common Trust Security" and
collectively, the "Common Trust Securities") (the Preferred Trust Securities and
the Common Trust Securities being hereinafter collectively referred to as "Trust
Securities") is to be issued by the Trust of a Common Trust Securities
Certificate for the Common Trust Security and the payment for the Common Trust
Security acquired by it, in accordance with the Trust Agreement, and as
described in the Prospectus, (ix) that the Common Trust Securities are issued
and sold to the Common Trust Security Holder in accordance with the Trust
Agreement, and as described in the Prospectus, (x) that the Trust derives no
income from or connected with sources within the State of Delaware and has no
assets, activities (other than having a Delaware trustee as required by the
Delaware Business Trust Act and filing documents with the Secretary of State) or
employees in the State of Delaware, and (xi) that the Trust is treated as a
grantor trust for federal income tax purposes. We have not participated in the
preparation of the Prospectus and assume no responsibility for its contents.

          This opinion is limited to the laws of the State of Delaware
(excluding the securities laws of the State of Delaware), and we have not
considered and express no opinion on the laws of any other jurisdiction,
including federal laws and rules and regulations relating thereto. Our opinions
are rendered only with respect to Delaware laws and rules, regulations and
orders thereunder that are currently in effect.

          Based upon the foregoing, and upon our examination of such questions
of law and statutes of the State of Delaware as we have considered necessary or
appropriate, and subject to the assumptions, qualifications, limitations and
exceptions set forth herein, we are of the opinion that:

          1.   The Trust has been duly created and is validly existing in
good standing as a business trust under the Delaware Business Trust Act, and all
filings required under the laws of the State of Delaware with respect to the
creation and valid existence of the Trust as a business trust have been made.

          2.   Under the Delaware Business Trust Act and the Trust Agreement,
the Trust has the trust power and authority to (i) own property and conduct its
business, all as described in the Prospectus, (ii) execute and deliver, and
perform its obligations under, the Underwriting Agreement, and (iii) issue, and
perform its obligations under, the Trust Securities.

          3.   The Trust Agreement is a legal, valid and binding agreement of
the Company and the Trustees, and is enforceable against the Company and the
Trustees, in accordance with its terms.

          4.   Under the Delaware Business Trust Act and the Trust Agreement,
the execution and delivery of the Underwriting Agreement by the Trust, and the
performance by the Trust of its obligations thereunder, have been duly
authorized by all requisite trust action on the part of the Trust.

          5.   No authorization, approval, consent or order of any Delaware
court or Delaware governmental authority or Delaware agency is required to be
obtained by the Trust solely in connection with the issuance and sale of the
Preferred Trust Securities.

          6.   The Preferred Trust Securities have been duly authorized by the
Trust Agreement and, when issued and sold in accordance with the Trust
Agreement, the Preferred Trust Securities will be, subject to the qualifications
set forth in paragraph 7 below, fully paid and nonassessable undivided
beneficial interests in the assets of the Trust.

          7.   The Preferred Trust Security Holders, as beneficial owners of the
Trust, will be entitled to the same limitation of personal liability extended to
stockholders of private corporations for profit organized under the General
Corporation Law of the State of Delaware. We note that the Preferred Trust
Security Holders may be obligated, pursuant to the Trust Agreement, to
(i) provide indemnity and/or security in connection with and pay taxes or
governmental charges arising from transfers or exchanges of Preferred Trust

Securities Certificates and the issuance of replacement Preferred Trust
Securities Certificates, and (ii) provide security or indemnity in connection
with requests of or directions to the Property Trustee to exercise its rights
and powers under the Trust Agreement.

          8.   Under the Delaware Business Trust Act and the Trust Agreement,
the issuance of the Preferred Trust Securities is not subject to preemptive
rights.

          9.   The issuance and sale by the Trust of the Trust Securities, the
execution, delivery and performance by the Trust of the Underwriting Agreement,
the consummation by the Trust of the transactions contemplated thereby and the
compliance by the Trust with its obligations thereunder do not violate (i) any
of the provisions of the Certificate or the Trust Agreement, or (ii) any
applicable Delaware law or Delaware administrative regulation.

          10.  The Preferred Trust Security Holders (other than those Preferred
Trust Security Holders who reside or are domiciled in the State of Delaware)
will have no liability for income taxes imposed by the State of Delaware solely
as a result of their participation in the Trust, and the Trust will not be
liable for any income tax imposed by the State of Delaware.

          The opinion expressed in paragraph 3 above is subject, as to
enforcement, to the effect upon the Trust Agreement of (i) bankruptcy,
insolvency, moratorium, receivership, reorganization, liquidation, fraudulent
conveyance or transfer and other similar laws relating to or affecting the
rights and remedies of creditors generally, (ii) principles of equity, including
applicable law relating to fiduciary duties (regardless of whether considered
and applied in a proceeding in equity or at law), and (iii) the effect of
applicable public policy on the enforceability of provisions relating to
indemnification or contribution.

          We consent to your relying as to matters of Delaware law upon this
opinion in connection with the Underwriting Agreement. We also consent to
Winthrop, Stimson, Putnam & Roberts', Worsham, Forsythe & Wooldridge, L.L.P.'s
and Thelen Reid & Priest LLP's relying as to matters of Delaware law upon this
opinion in connection with opinions to be rendered by them on the date hereof
pursuant to the Underwriting Agreement. Further, we consent to the reliance by
The Bank of New York (in its capacity as Debenture Trustee under the
Subordinated Indenture, as trustee under the Guarantee, and as Property Trustee
under the Trust Agreement) and The Bank of New York (Delaware) (in its capacity
as Delaware Trustee under the Trust Agreement) as to matters of Delaware law
upon this opinion in connection with the matters set forth herein. Except as

             [LETTERHEAD OF WORSHAM, FORSYTHE & WOOLDRIDGE, L.L.P.]





                                           [Date]







as Representatives of Underwriters named in Schedule II
to the Underwriting Agreement, as herein defined

c/o




Ladies and Gentlemen:

          We have acted as General Counsel to TXU Gas Company, a Texas
corporation (the "Company"), in connection with the transactions contemplated by
the Underwriting Agreement dated              , 1999 among the Company, [Name of
                                 -------------
Trust] (the "Trust") and you (the "Underwriting Agreement"), including, among
others, (i) the issuance by the Trust, a statutory business trust organized
under the Delaware Business Trust Act (the "Delaware Act"), of Preferred Trust
Securities (the "Preferred Trust Securities") having an aggregate liquidation
amount of $       000,000, (ii) the issuance by the Company of $
           -------                                             ----------------

principal amount of its Junior Subordinated Debentures, Series       (the
                                                               -----
"Debentures") and (iii) the guarantee by the Company of the Preferred Trust
Securities pursuant to a Guarantee Agreement, dated the date hereof, between the
Company and The Bank of New York, as trustee (the "Guarantee").


                                      IV-1

<PAGE>



          Terms not otherwise defined herein are used with the meanings ascribed
to them in the Underwriting Agreement.

          In so acting we have participated in or reviewed the corporate
proceedings in connection with the authorization, execution and delivery of the
Underwriting Agreement, the Trust Agreement, the Indenture, the Debentures and
the Guarantee. We have also examined such other documents and satisfied
ourselves as to such other matters as we have deemed necessary as a basis for
the conclusions of law contained in the opinions expressed below. We have relied
as to various questions of fact upon the representations and warranties of the
Company contained in the Underwriting Agreement and, where we deemed
appropriate, on certificates of public officials. We have relied upon a
certificate of the Indenture Trustee as to the authentication of the Debentures.
In our examination we have assumed the genuineness of all signatures and the
authenticity of all documents submitted to us as originals and the conformity to
original documents of all documents submitted to us as photostatic or certified
copies.

          Upon the basis of our familiarity with these transactions and with the
affairs and properties of the Company generally, we are of the opinion that:

          1.   The Company is a corporation duly authorized, validly existing
and in good standing under the laws of the State of Texas, and has the corporate
power and authority: (a) to execute, deliver and perform its obligations under
the Underwriting Agreement and the Indenture, (b) to issue the Debentures and
the Guarantee and to incur the indebtedness to be evidenced thereby, and (c) to
own its property and assets and to conduct the business which it is now
conducting.

          2.   The Underwriting Agreement has been duly authorized, executed and
delivered by the Company.

          3.   The Indenture, the Trust Agreement and the Guarantee have been
duly qualified under the Trust Indenture Act.

          4.   The Debentures and the Indenture have been duly authorized,
executed and delivered by the Company, the Debentures are entitled to the
benefits of the Indenture, and the Debentures and the Indenture are legal, valid
and binding obligations of the Company enforceable against the Company in
accordance with their respective terms, subject to the effect of bankruptcy,
insolvency, reorganization, fraudulent conveyance, receivership, moratorium and


                                      IV-2

<PAGE>



other laws affecting the rights and remedies of creditors generally and of
general principles of equity.

          5.   The Guarantee has been duly authorized, executed and delivered by
the Company, and is enforceable against the Company in accordance with its
terms, subject to the effect of bankruptcy, insolvency, reorganization,
fraudulent conveyance, receivership, moratorium and other laws affecting the
rights and remedies of creditors generally and of general principles of equity.

          6.   The statements made in the Prospectus under the captions
"Description of TXU Capital's Preferred Trust Securities and Common Trust
Securities," "Description of the Junior Subordinated Debentures," "Description
of the Guarantee", "Certain Terms of the Preferred Trust Securities" and
"Certain Terms of the Junior Subordinated Debentures", insofar as they purport
to constitute summaries of the terms of the documents referred to therein,
constitute accurate summaries of the terms of such documents in all material
respects;

          7.   Neither the Company nor the Trust is an investment company within
the meaning of the Investment Company Act of 1940, as amended.

          8.   The Trust is duly qualified to transact business in the State of
Texas as a foreign limited liability company. Under Texas law, the liability, if
any, of holders of Preferred Trust Securities for the debts, liabilities and
obligations of the Trust for which they are not otherwise liable by statute or
agreement will be governed by the Delaware Act.

          9.   Other than as stated in the Registration Statement and the
Prospectus, there are no material pending legal proceedings to which the Company
is a party or of which property of the Company is the subject which depart from
the ordinary routine litigation incident to the kind of business conducted by
the Company, and to our knowledge no such proceedings are contemplated;

          10.  The Registration Statement, as of the Effective Date, and the
Prospectus at the time it was filed with the Commission pursuant to Rule 424
under the Securities Act (except for financial statements and schedules and
other financial and statistical data contained or incorporated by reference
therein and except for that part of the Registration Statement that constitutes
the Forms T-1, as to which we do not express any opinion) complied as to form in
all material respects with the Securities Act and the applicable instructions,


                                      IV-3


<PAGE>


rules and regulations of the Commission thereunder; the Incorporated Documents
(except as to the financial statements and schedules and other financial and
statistical data contained therein, as to which we do not express any opinion),
at the time they were filed with the Commission, complied as to form in all
material respects with the requirements of the Exchange Act and the applicable
instructions, rules and regulations of the Commission thereunder; and the
Registration Statement has become and is effective under the Securities Act and,
to our best knowledge, no proceedings for a stop order with respect thereto are
pending or threatened under Section 8 of the Securities Act.

          11.  No other approval, authorization, consent or order of any public
board or body (other than in connection or in compliance with the provisions of
the blue-sky laws of any jurisdiction) is legally required for the authorization
of the issue and sale by the Company of the Debentures and the issuance by the
Company of the Guarantee.

          In the course of the preparation of the information relating to the
Company contained in the Prospectus (including the documents incorporated
therein by reference) we had discussions with certain of its officers and
representatives and certain officers and representatives of certain of its
subsidiaries, with other counsel for the Company, with Deloitte & Touche LLP,
the Company's independent certified public accountants who audited certain of
the financial statements contained in documents incorporated by reference in the
Registration Statement and the Prospectus, and with certain of your officers and
employees and your counsel, but we made no independent verification of the
accuracy or completeness of the representations and statements made to us by the
Company or the information included by the Company in the Prospectus (including
the documents incorporated therein by reference) and take no responsibility
therefor except as set forth in paragraph 6 above. However, our examination of
the information relating to the Company contained in the Registration Statement
and the Prospectus and our discussions did not disclose to us anything which
gives us reason to believe that (except as to financial statements and schedules
and other financial and statistical data and except as to that part of the
Registration Statement that constitutes the Forms T-1, as to which we do not
express any belief) (i) the Registration Statement, as of the Effective Date,
included an untrue statement of a material fact or omitted to state a material
fact required to be stated therein or necessary to make the statements therein
not misleading or (ii) the Prospectus at the time it was filed with the


                                      IV-4

<PAGE>


Commission pursuant to Rule 424, included, or on the date hereof includes an
untrue statement of a material fact or on such dates omitted or omits to state a
material fact necessary in order to make the statements therein, in the light of
the circumstances under which they were made, not misleading.

          We are members of the State Bar of Texas and do not hold ourselves out
as experts in the laws of the State of New York. As to all matters of New York
law, we have, with your consent, relied upon the opinion of even date herewith
of Thelen Reid & Priest LLP, New York, New York, of Counsel to the Company; as
to all matters of Delaware law, we have, with your consent, relied upon the
opinion of even date herewith of Richards, Layton & Finger, P.A., Wilmington,
Delaware, special counsel for the Company and the Trust.

                                        Very truly yours,

                                        WORSHAM, FORSYTHE &

upon an opinion of even date herewith addressed to you by Worsham, Forsythe &
Wooldridge, L.L.P., Dallas, Texas, General Counsel for the Company, as to the
matters covered in such opinion relating to Texas law. We have reviewed such
opinion and believe that it is satisfactory and that you and we are justified in
relying thereon. We understand that you are relying, for all matters of Delaware
law, upon an opinion of even date herewith addressed to you by Richards, Layton

          We have, in addition, examined the documents described in the list of

accordance with their respective terms, subject to the effect of bankruptcy,
insolvency, reorganization, fraudulent conveyance, receivership, moratorium and
other laws affecting the rights and remedies of creditors generally and of
general principles of equity.

          4.   The Guarantee has been duly authorized, executed and delivered by
the Company, and is enforceable against the Company in accordance with its
terms, subject to the effect of bankruptcy, insolvency, reorganization,
fraudulent conveyance, receivership, moratorium and other laws affecting the
rights and remedies of creditors generally and of general principles of equity.

the issuance and sale of the Preferred Trust Securities, will be, and neither
the Company nor the Trust is directly or indirectly controlled by, or acting on
behalf of any person which is, an investment company within the meaning of the

Prospectus at the time it was filed with the Commission pursuant to Rule 424
(except in each case as to financial statements and schedules and other
financial and statistical data contained or incorporated by reference therein

          In passing upon the form of the Registration Statement and the form of
the Prospectus, we necessarily assume the correctness and completeness of the
statements made by the Company and the information included in the Registration
Statement and the Prospectus and take no responsibility therefor, except insofar
as such statements relate to us and as set forth in paragraph 5 above. In the

public accountants who audited certain of the financial statements contained in
documents incorporated by reference in the Registration Statement and the
Prospectus, and with certain of your representatives. Our examination of the
Registration Statement and the Prospectus and our discussions did not disclose
to us any information which gives us reason to believe that at the Effective
Date the Registration Statement contained an untrue statement of a material fact
or omitted to state a material fact required to be stated therein or necessary
to make the statements therein not misleading or that the Prospectus, at the
time it was filed with the Commission pursuant to Rule 424, or at the date
hereof, included or includes an untrue statement of a material fact or omitted
or omits to state a material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading. We do not express any opinion or belief as to the financial
statements and schedules or other financial or statistical data contained or
incorporated by reference in the Registration Statement or Prospectus or as to
that part of the Registration Statement that constitutes the Forms T-1.

          This opinion is given to you solely for the use of the several
Underwriters in connection with the Underwriting Agreement and the transactions
contemplated thereunder and may not be relied upon by any other person or for
any other purpose.


                                        Very truly yours,

payable, and punctually paid or duly provided for, on any Interest Payment Date
will, as provided in such Indenture, be paid to the Person in whose name this
Security (or one or more Predecessor Securities) is registered at the close of
business on the Regular Record Date for such interest, which shall be the

day of the calendar month next preceding such Interest Payment Date. Any such
interest not so punctually paid or duly provided for will forthwith cease to be
payable to the Holder on such Regular Record Date and may either be paid to the
Person in whose name this Security (or one or more Predecessor Securities) is
registered at the close of business on a Special Record Date for the payment of
such Defaulted Interest to be fixed by the Trustee, notice whereof shall be
given to Holders of Securities of this series not less than 10 days prior to
such Special Record Date, or be paid at any time in any other lawful manner not
inconsistent with the requirements of any securities exchange on which the
Securities of this series may be listed, and upon such notice as may be required
by such exchange, all as more fully provided in the Indenture referred to on the
reverse hereof.

tender for payment of public and private debts, provided, however, that, at the
option of the Company, interest on this Security may be paid by check mailed to
the address of the person entitled thereto, as such address shall appear on the
Security Register.

                  Reference is hereby made to the further provisions of this
Security set forth on the reverse hereof, which further provisions shall for all
purposes have the same effect as if set forth at this place.

                  Unless the certificate of authentication hereon has been
executed by the Trustee referred to on the reverse hereof by manual signature,
this Security shall not be entitled to any benefit under the Indenture or be
valid or obligatory for any purpose.

                  IN WITNESS WHEREOF, the Company has caused this instrument to
be duly executed.

                       [FORM OF REVERSE OF SERIES   NOTE]
                                                  -

                  This Security is one of a duly authorized issue of securities
of the Company (herein called the "Securities"), issued and to be issued in one
or more series under an Indenture, dated as of January 1, 1998 (herein, together
with any amendments thereto, called the "Indenture", which term shall have the
meaning assigned to it in such instrument), between the Company and The Bank of
New York, as Trustee (herein called the "Trustee", which term includes any
successor trustee under the Indenture), and reference is hereby made to the
Indenture, including the Board Resolutions and Officer's Certificate filed with
the Trustee on           ,      creating the series designated on the face
               ----------  ----
hereof, for a statement of the respective rights, limitations of rights, duties
and immunities thereunder of the Company, the Trustee and the Holders of the
Securities and of the terms upon which the Securities are, and are to be,
authenticated and delivered. This Security is one of the series designated on
the face hereof[, limited in aggregate principal amount to $           ].
                                                            -----------

                  The Securities of this series will be redeemable as a whole at
any time or in part from time to time, at the option of the Company, upon not
less than 30 nor more than 60 days' notice given as provided in the Indenture,
at a Redemption Price equal to     % of the principal amount of such Securities
                               ----
of this series.

                  Unless the Company defaults in payment of the Redemption
Price, on and after the Redemption Date interest will cease to accrue on the
Securities of this series or portions thereof called for redemption.

                  The Indenture contains provisions for defeasance at any time
of the entire indebtedness of this Security upon compliance with certain
conditions set forth in the Indenture, including the Officer's Certificate
described above.

                  If an Event of Default with respect to Securities of this
series shall occur and be continuing, the principal of the Securities of this
series may be declared due and payable in the manner and with the effect
provided in the Indenture.

                  The Indenture permits, with certain exceptions as therein
provided, the amendment thereof and the modification of the rights and
obligations of the Company and the rights of the Holders of the Securities of
each series to be affected under the Indenture at any time by the Company and
the Trustee with the consent of the Holders of a majority in principal amount of
the Securities at the time Outstanding of all series to be affected. The
Indenture contains provisions permitting the Holders of a majority in aggregate
principal amount of the Securities of all series then Outstanding to waive
compliance by the Company with certain restrictive provisions of the Indenture.
The Indenture also contains provisions permitting the Holders of specified
percentages in principal amount of the Securities of each series at the time
Outstanding, on behalf of the Holders of all Securities of such series, to waive
certain past defaults under the Indenture and their consequences. Any such
consent or waiver by the Holder of this Security shall be conclusive and binding
upon such Holder and upon all future Holders of this Security and of any
Security issued upon the registration of transfer hereof or in exchange herefor
or in lieu hereof, whether or not notation of such consent or waiver is made
upon this Security.

                  As provided in and subject to the provisions of the Indenture,
the Holder of this Security shall not have the right to institute any proceeding
with respect to the Indenture or for the appointment of a receiver or trustee or
for any other remedy thereunder, unless such Holder shall have previously given
the Trustee written notice of a continuing Event of Default with respect to the
Securities of this series, the Holders of a majority in aggregate principal
amount of the Securities of all series at the time Outstanding in respect of
which an Event of Default shall have occurred and be continuing shall have made
written request to the Trustee to institute proceedings in respect of such Event
of Default as Trustee and offered the Trustee reasonable indemnity, and the
Trustee shall not have received from the Holders of a majority in aggregate
principal amount of Securities of all series at the time Outstanding in respect
of which an Event of Default shall have occurred and be continuing a direction
inconsistent with such request, and shall have failed to institute any such
proceeding, for 60 days after receipt of such notice, request and offer of
indemnity. The foregoing shall not apply to any suit instituted by the Holder
of this Security for the enforcement of any payment of principal hereof or any
premium or interest hereon on or after the respective due dates expressed
herein.

                  No reference herein to the Indenture and no provision of this
Security or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the principal of and any
premium and interest on this Security at the times, place and rate, and in the
coin or currency, herein prescribed.

                  The Securities of this series are issuable only in registered
form without coupons in denominations of $      and any integral multiple
                                          -----
thereof. As provided in the Indenture and subject to certain limitations therein
set forth, Securities of this series are exchangeable for a like aggregate
principal amount of Securities of this series and of like tenor and of
authorized denominations, as requested by the Holder surrendering the same.

                  No service charge shall be made for any such registration of
transfer or exchange, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

                  The Company, the Trustee and any agent of the Company or the
Trustee may treat the Person in whose name this Security is registered as the
absolute owner hereof for all purposes, whether or not this Security be overdue,
and neither the Company, the Trustee nor any such agent shall be affected by
notice to the contrary.

                  All terms used in this Security which are defined in the
Indenture shall have the meanings assigned to them in the Indenture.

elects to issue certificated Securities to beneficial owners. Any such exchange
shall be made upon receipt by the Trustee of a Company Order therefor and

such denominations as shall be certified to the Company and the Trustee by the
Depositary.]

Trustee of the Trust, is hereby authorized and, to the extent so required,

Trust any such document unless required by the rules and regulations of the
Commission, the Exchange or state securities or blue sky laws. In connection
with the filings referred to above, the Depositor and each Trustee, solely in
its or her capacity as trustee of the Trust, hereby constitutes and appoints

substitute or substitutes, shall do or cause to be done by virtue hereof.

counterparts.

                  6. The number of Trustees initially shall be three (3) and
thereafter the number of Trustees shall be such number as shall be fixed from
time to time by a written instrument signed by the Depositor which may increase
or decrease the number of Trustees; provided, however, that to the extent
required by the Business Trust Act, one Trustee shall be either a natural
person who is a resident of the State of Delaware, or, if not a natural person,
an entity which has its principal place of business in the State of Delaware and
otherwise meets the requirements of applicable Delaware law. Subject to the
foregoing, the Depositor is entitled to appoint or remove without cause any
Trustee at any time. Any one or more of the Trustees may resign upon thirty
days prior written notice to Depositor.

                  7. The Depositor shall have the right to dissolve the Trust at
any time prior to the issuance of any Preferred Trust Security. Upon dissolution

               (xi) the taking of any action incidental to the foregoing as the
          Administrative Trustees may from time to time determine is necessary
          or advisable to protect and conserve the Trust Property for the
          benefit of the Securityholders (without consideration of the effect of
          any such action on any particular Securityholder).

Trust Agreement.

          (b) So long as this Trust Agreement remains in effect, the Trust (or
the Trustees acting on behalf of the Trust) shall not undertake any business,
activities or transaction except as expressly provided herein or contemplated
hereby. In particular, the Trustees shall not (i) acquire any investments or
engage in any activities not authorized by this Trust Agreement, (ii) sell,
assign, transfer, exchange, pledge, set-off or otherwise dispose of any of the
Trust Property or interests therein, including to Securityholders, except as
expressly provided herein, (iii) take any action that would cause the Trust to
fail or cease to qualify as a "grantor trust" for United States federal income
tax purposes and not as an association taxable as a corporation, (iv) incur any
indebtedness for borrowed money or (v) take or consent to any action that would
result in the placement of a Lien on any of the Trust Property. The Trustees
shall defend all claims and demands of all Persons at any time claiming any Lien
on any of the Trust Property adverse to the interest of the Trust or the
Securityholders in their capacity as Securityholders.

          (c) In connection with the issue of the Preferred Trust Securities,
the Depositor and the Administrative Trustees, acting singly or together, (and,
in the case of (iii) and (v) below, Robert J. Reger, Jr., as authorized
representative of the Trust) shall have the right and responsibility to assist
the Trust with respect to, or effect on behalf of the Trust, the following (and


                                     -14-
<PAGE>


any actions taken by the Depositor in furtherance of the following prior to the
date of this Trust Agreement are hereby ratified and confirmed in all respects):

               (i) to prepare for filing by the Trust with the Commission and to
          execute a registration statement on Form S-3 in relation to the
          Preferred Trust Securities, including any amendments thereto;

               (ii) to determine the States in which to take appropriate action
          to qualify or register for sale all or part of the Preferred Trust
          Securities and to do any and all such acts, other than actions which
          must be taken by or on behalf of the Trust, and advise the Trustees of
          actions they must take on behalf of the Trust, and prepare for
          execution and filing any documents to be executed and filed by the
          Trust or on behalf of the Trust, as the Depositor deems necessary or
          advisable in order to comply with the applicable laws of any such
          States;

               (iii) to execute and deliver on behalf of the Trust the
          Underwriting Agreement and such other agreements as may be necessary
          or desirable in connection with the consummation thereof;

               (iv) to select the investment banker or bankers to act as
          underwriters with respect to the offer and sale by the Trust of
          Preferred Trust Securities ("Offer") and negotiate the terms of an
          Underwriting Agreement and pricing agreement providing for the Offer;
          and

               (v) to take any other actions necessary or desirable to carry out
          any of the foregoing activities.

          (d) Notwithstanding anything herein to the contrary, the
Administrative Trustees are authorized and directed to conduct the affairs of
the Trust and to operate the Trust so that the Trust will not be deemed to be an
"investment company" required to be registered under the Investment Company Act
or classified other than as a "grantor trust" for United States federal income
tax purposes and not as an association taxable as a corporation and so that the
Debentures will be treated as indebtedness of the Debenture Issuer for United
States federal income tax purposes. In this connection, the Depositor and the
Administrative Trustees are authorized to take any action, not inconsistent with
applicable law, the certificate of trust filed with the Secretary of State of
the State of Delaware with respect to the Trust (as amended or restated from
time to time, the "Certificate of Trust") or this Trust Agreement, that each of
the Depositor and the Administrative Trustees determines in its discretion to be
necessary or desirable for such purposes, as long as such action does not
materially adversely affect the interests of the Holders of the Preferred Trust
Securities.

          SECTION 2.08. ASSETS OF TRUST. The assets of the Trust shall consist
of the Trust Property.

          SECTION 2.09. TITLE TO TRUST PROPERTY. Legal title to all Trust
Property shall be vested at all times in the Property Trustee (in its capacity
as such) and shall be held and administered by the Property Trustee for the
benefit of the Securityholders in accordance with this Trust Agreement.


                                   ARTICLE III

                                 PAYMENT ACCOUNT

          SECTION 3.01. PAYMENT ACCOUNT.

          (a) On or prior to the Closing Date, the Property Trustee shall
establish the Payment Account. The Property Trustee and the Paying Agent
appointed by the Administrative Trustees shall have exclusive control and sole
right of withdrawal with respect to the Payment Account for the purpose of
making deposits in and withdrawals from the Payment Account in accordance with
this Trust Agreement. All monies and other property deposited or held from time
to time in the Payment Account shall be held by the Property Trustee in the
Payment Account for the exclusive benefit of the Holders of Trust Securities and
for distribution as herein provided, including (and subject to) any priority of
payments provided for herein. The Property Trustee shall have no liability in
any respect whatsoever in regards to any moneys or other property deposited in
the Payment Account at an institution other than the Property Trustee.

          (b) The Property Trustee shall deposit in the Payment Account,
promptly upon receipt, all payments of principal or interest on, and any other
payments or proceeds with respect to, the Debentures. Amounts held in the
Payment Account shall not be invested by the Property Trustee pending
distribution thereof.


                                   ARTICLE IV

                            DISTRIBUTIONS; REDEMPTION

          SECTION 4.01. DISTRIBUTIONS.

          (a) Distributions on the Trust Securities shall be cumulative, and
will accumulate whether or not there are funds of the Trust available for the
payment of Distributions. Distributions shall accrue from the Closing Date, and,
except in the event that the Depositor exercises its right to extend the
interest payment period for the Debentures pursuant to Section 311 of the
Subordinated Indenture, shall be payable quarterly in arrears on _________ 1,
_________ 1, __________ 1, and __________ 1 of each year, commencing on _______
1, ____. If any date on which Distributions are otherwise payable on the Trust
Securities is not a Business Day, then the payment of such Distribution shall be
made on the next succeeding day which is a Business Day (and without any
interest or other payment in respect of any such delay) in each case, with the


                                     -16-
<PAGE>


same force and effect as if made on such date (each date on which Distributions
are payable in accordance with this Section 4.01(a) a "Distribution Date").

          (b) Distributions payable on the Trust Securities shall be fixed at a
rate of __% per annum of the Liquidation Amount of the Trust Securities. The
amount of Distributions payable for any quarterly period shall be computed on
the same basis as interest is calculated on the Debentures. If the interest
payment period for the Debentures is extended pursuant to Section 311 of the
Subordinated Indenture, then Distributions on the Trust Securities will be
deferred for the period equal to the extension of the interest payment period
for the Debentures and the rate per annum at which Distributions on the Trust
Securities accumulate shall be increased by an amount such that the aggregate
amount of Distributions that accumulate on all Trust Securities during any such
extended interest payment period is equal to the aggregate amount of interest
(including, to the extent permitted by law, interest payable on unpaid interest
at the percentage rate per annum set forth above, compounded quarterly) that
accrues during any such extended interest payment period on the Debentures. The
amount of Distributions payable for any period shall include the Additional
Amounts, if any.

          (c) Distributions on the Trust Securities shall be made and shall be
deemed payable on each Distribution Date only to the extent that the Trust has
funds available in the Payment Account for the payment of such Distributions.

          (d) Distributions on the Trust Securities with respect to a
Distribution Date shall be payable to the Holders thereof as they appear on the
Securities Register for the Trust Securities on the relevant record date, which
shall be one Business Day prior to the relevant Distribution Date, if Trust
Securities are in book-entry only form, and 15 days prior to the relevant
Distribution Date if Trust Securities are not in book-entry only form.

          SECTION 4.02. REDEMPTION. (a) On each Debenture Redemption Date and at
the maturity date ("Maturity Date") for the Debentures (as defined in the
Subordinated Indenture), the Property Trustee will be required to redeem a Like
Amount of Trust Securities at the Redemption Price plus accumulated and unpaid
Distributions to the Redemption Date or Maturity Date, as the case may be.

          (b) Notice of redemption shall be given by the Property Trustee by
first-class mail, postage prepaid, mailed not less than 30 nor more than 60 days
prior to the Redemption Date to each Holder of Trust Securities to be redeemed,
at such Holder's address appearing in the Security Register. All notices of
redemption or liquidation shall state:

               (i) the Redemption Date;

               (ii) the Redemption Price and the amount of accumulated and
          unpaid Distributions to be paid on the Redemption Date;

               (iii) the CUSIP number;


                                     -17-
<PAGE>


               (iv) if less than all the Outstanding Trust Securities are to be
          redeemed, the identification and the total Liquidation Amount of the
          particular Trust Securities to be redeemed; and

               (v) that on the Redemption Date the Redemption Price plus
          accumulated and unpaid Distributions to the Redemption Date will
          become due and payable upon each such Trust Security to be redeemed
          and that Distributions thereon will cease to accrue on and after said
          date.

          (c) The Trust Securities redeemed on each Redemption Date shall be
redeemed at the Redemption Price plus accumulated and unpaid Distributions to
the Redemption Date with the proceeds from the contemporaneous redemption of
Debentures. Redemptions of the Trust Securities shall be made and the Redemption
Price plus accumulated and unpaid Distributions to the Redemption Date shall be
deemed payable on each Redemption Date only to the extent that the Trust has
funds immediately available in the Payment Account for such payment.

          (d) If the Property Trustee gives a notice of redemption in respect of
any Preferred Trust Securities, then, by 12:00 noon, New York time, on the
Redemption Date, subject to Section 4.02(c), the Property Trustee shall
irrevocably deposit with the Paying Agent funds sufficient to pay the applicable
Redemption Price plus accumulated and unpaid Distributions to the Redemption
Date and will give the Paying Agent irrevocable instructions and authority to
pay the Redemption Price plus accumulated and unpaid Distributions to the
Redemption Date to the Holders thereof upon surrender of their Preferred Trust
Securities Certificates and Common Trust Securities Certificates.
Notwithstanding the foregoing, Distributions on the Trust Securities with
respect to Distribution Dates occurring on or prior to the Redemption Date for
any Trust Securities called for redemption shall be payable to the Holders of
such Trust Securities as they appear on the Securities Register for the Trust
Securities on the relevant record dates for the related Distribution Dates. If
notice of redemption shall have been given and funds deposited as required, then
on the Redemption Date, all rights of Securityholders holding Trust Securities
so called for redemption will cease, except the right of such Securityholders to
receive the Redemption Price plus accumulated and unpaid Distributions to the
Redemption Date thereof, but without interest thereon, and such Trust Securities
will cease to be Outstanding. In the event that any Redemption Date is not a
Business Day, then payment of the Redemption Price payable on such date plus
accumulated and unpaid Distributions to such Redemption Date shall be made on
the next succeeding day which is a Business Day (and without any interest or
other payment in respect of any such delay) with the same force and effect as if
made on such date. In the event that payment of the Redemption Price plus
accumulated and unpaid Distributions in respect of any Trust Securities called
for redemption is improperly withheld or refused and not paid either by the
Trust or by the Depositor pursuant to the Guarantee, Distributions on such Trust
Securities will continue to accrue, at the then applicable rate, from the
Redemption Date originally established by the Trust for such Trust Securities to
the date such Redemption Price plus accumulated and unpaid Distributions is
actually paid, in which case the actual payment date will be deemed the date


                                     -18-
<PAGE>


fixed for redemption for purposes of calculating the Redemption Price plus
accumulated and unpaid Distributions to such date.

          (e) Payment of the Redemption Price on the Trust Securities shall be
made to the Holders thereof as they appear on the Securities Register for the
Trust Securities on the Redemption Date.

          (f) If less than all the Outstanding Trust Securities are to be
redeemed on a Redemption Date, then the aggregate Liquidation Amount of Trust
Securities to be redeemed shall be allocated to the Common Trust Securities and
to the Preferred Trust Securities in the proportion that the aggregate
Liquidation Amount of each is to the aggregate Liquidation Amount of all
outstanding Trust Securities. The particular Preferred Trust Securities to be
redeemed shall be selected not more than 60 days prior to the Redemption Date by
the Property Trustee from the Outstanding Preferred Trust Securities not
previously called for redemption, by such method as the Property Trustee shall
deem fair and appropriate and which may provide for the selection for redemption
of portions (equal to $_____ or integral multiples thereof) of the Liquidation
Amount of Preferred Trust Securities of a denomination larger than $_____. The
Property Trustee shall promptly notify the Transfer Agent and Registrar in
writing of the Preferred Trust Securities selected for redemption and, in the
case of any Preferred Trust Securities selected for partial redemption, the
Liquidation Amount thereof to be redeemed. For all purposes of this Trust
Agreement, unless the context otherwise requires, all provisions relating to the
redemption of Preferred Trust Securities shall relate, in the case of any
Preferred Trust Securities redeemed or to be redeemed only in part, to the
portion of the Liquidation Amount of Preferred Trust Securities which has been
or is to be redeemed.

          SECTION 4.03. SUBORDINATION OF COMMON TRUST SECURITIES. (a) Payment of
Distributions (including Additional Amounts, if applicable) on, and the
Redemption Price plus accumulated and unpaid Distributions of, the Trust
Securities, as applicable, shall be made pro rata based on the Liquidation
Amount of the Trust Securities; provided, however, that if on any Distribution
Date or Redemption Date an Event of Default shall have occurred and be
continuing, no payment of any Distribution (including Additional Amounts, if
applicable) on, or Redemption Price plus accumulated and unpaid Distributions
of, any Common Trust Security, and no other payment on account of the
redemption, liquidation or other acquisition of Common Trust Securities, shall
be made unless payment in full in cash of all accumulated and unpaid
Distributions (including Additional Amounts, if applicable) on all Outstanding
Preferred Trust Securities for all distribution periods terminating on or prior
thereto, or in the case of payment of the Redemption Price plus accumulated and
unpaid Distributions the full amount of such Redemption Price plus accumulated
and unpaid Distributions on all Outstanding Preferred Trust Securities, shall
have been made or provided for, and all funds immediately available to the
Property Trustee shall first be applied to the payment in full in cash of all
Distributions (including Additional Amounts, if applicable) on, or Redemption
Price plus accumulated and unpaid Distributions of, Preferred Trust Securities
then due and payable.


                                     -19-
<PAGE>


          (b) In the case of the occurrence of any Event of Default resulting
from a Debenture Event of Default, the Holder of Common Trust Securities will be
deemed to have waived any such Event of Default under this Trust Agreement until
the effect of all such Events of Default with respect to the Preferred Trust
Securities have been cured, waived or otherwise eliminated. Until all such
Events of Default under this Trust Agreement with respect to the Preferred Trust
Securities have been so cured, waived or otherwise eliminated, the Property
Trustee shall act solely on behalf of the Holders of the Preferred Trust
Securities and not the Holder of the Common Trust Securities, and only the
Holders of the Preferred Trust Securities will have the right to direct the
Property Trustee to act on their behalf.

          SECTION 4.04. PAYMENT PROCEDURES. Payments in respect of the Preferred
Trust Securities shall be made by check mailed to the address of the Person
entitled thereto as such address shall appear on the Securities Register or, if
the Preferred Trust Securities are held by a Securities Depository, such
Distributions shall be made to the Securities Depository, which shall credit the
relevant Persons' accounts at such Securities Depository on the applicable
Distribution Dates. Payments in respect of the Common Trust Securities shall be
made in such manner as shall be mutually agreed between the Administrative
Trustees and the Holder of the Common Trust Securities.

          SECTION 4.05. TAX RETURNS AND REPORTS. The Administrative Trustees
shall prepare (or cause to be prepared), at the Depositor's expense and
direction, and file all United States federal, state and local tax and
information returns and reports required to be filed by or in respect of the
Trust. In this regard, the Administrative Trustees shall (a) prepare and file
(or cause to be prepared or filed) the Internal Revenue Service Form 1041 (or
any successor form) required to be filed in respect of the Trust in each taxable
year of the Trust and (b) prepare and furnish (or cause to be prepared and
furnished) to each Securityholder the related Internal Revenue Service Form
1099, or any successor form or the information required to be provided on such
form. The Administrative Trustees shall provide the Depositor and the Property
Trustee with a copy of all such returns, reports and schedules promptly after
such filing or furnishing. The Trustees shall comply with United States federal
withholding and backup withholding tax laws and information reporting
requirements with respect to any payments to Securityholders under the Trust
Securities.

          SECTION 4.06. PAYMENTS UNDER INDENTURE. Any amount payable
hereunder to any Holder of Preferred Trust Securities shall be reduced by the
amount of any corresponding payment such Holder has directly received pursuant
to Section 808 of the Subordinated Indenture. Notwithstanding the provisions
hereunder to the contrary, Securityholders acknowledge that any Holder of
Preferred Trust Securities that receives payment under Section 808 of the
Subordinated Indenture may receive amounts greater than the amount such Holder
may be entitled to receive pursuant to the other provisions of this Trust
Agreement.

on behalf of the Trust by manual or facsimile signature of at least one
Administrative Trustee and, if executed on behalf of the Trust by facsimile

Agent and Registrar or its agent. Trust Securities Certificates bearing the
manual signatures of individuals who were, at the time when such signatures
shall have been affixed, authorized to sign on behalf of the Trust and, if
executed on behalf of the Trust by facsimile signature, countersigned by the
Transfer Agent and Registrar or its agent, shall be validly issued and entitled
to the benefits of this Trust Agreement, notwithstanding that such individuals
or any of them shall have ceased to be so authorized prior to the delivery of
such Trust Securities Certificates or did not hold such offices at the date of

Securities Certificate shall become a Securityholder, and shall be entitled to
the rights and subject to the obligations of a Securityholder hereunder, upon
due registration of such Trust Securities Certificate in such transferee's name
pursuant to Section 5.04 or 5.12.

          SECTION 5.03. EXECUTION AND DELIVERY OF TRUST SECURITIES CERTIFICATES.

in the case of Preferred Trust Securities executed by facsimile signature,
countersigned by the Transfer Agent and Registrar, or its agent, and delivered
to or upon the written order of the Depositor signed by its chairman of the
board, any of its vice presidents or its treasurer, without further corporate
action by the Depositor, in authorized denominations. The Depositor agrees to
indemnify, defend and hold The Bank of New York harmless against any and all
costs and liabilities incurred without negligence arising out of or in
connection with any such countersigning by it.

          SECTION 5.04. REGISTRATION OF TRANSFER AND EXCHANGE OF TRUST
SECURITIES CERTIFICATES. The Transfer Agent and Registrar shall keep or cause to
be kept, at the office or agency maintained pursuant to Section 5.08, a
Securities Register in which, subject to such reasonable regulations as it may

the Transfer Agent and Registrar duly executed by the Holder or such Holder's
attorney duly authorized in writing. Each Preferred Trust Securities Certificate
surrendered for registration of transfer or exchange shall be canceled and
subsequently disposed of by the Administrative Trustees in accordance with
customary practice. The Trust shall not be required to (i) issue, register the
transfer of, or exchange any Preferred Trust Securities during a period
beginning at the opening of business 15 calendar days before the day of mailing
of a notice of redemption of any Preferred Trust Securities called for
redemption and ending at the close of business on the day of such mailing or
(ii) register the transfer of or exchange any Preferred Trust Securities so
selected for redemption, in whole or in part, except the unredeemed portion of
any such Preferred Trust Securities being redeemed in part.

          No service charge shall be made for any registration of transfer or
exchange of Preferred Trust Securities Certificates, but the Transfer Agent and
Registrar may require payment of a sum sufficient to cover any tax or
governmental charge that may be imposed in connection with any transfer or
exchange of Preferred Trust Securities Certificates.

          SECTION 5.05. MUTILATED, DESTROYED, LOST OR STOLEN TRUST SECURITIES
CERTIFICATES. If (a) any mutilated Trust Securities Certificate shall be
surrendered to the Transfer Agent and Registrar, or if the Transfer Agent and
Registrar shall receive evidence to its satisfaction of the destruction, loss or
theft of any Trust Securities Certificate and (b) there shall be delivered to
the Transfer Agent and Registrar and the Administrative Trustees such security
or indemnity as may be required by them to save each of them and the Depositor
harmless, then in the absence of notice that such Trust Securities Certificate
shall have been acquired by a bona fide purchaser, the Administrative Trustees,
or any one of them, on behalf of the Trust shall execute by manual or facsimile
signature and, if execution on behalf of the Trust is by facsimile signature,
countersigned by a Transfer Agent and Registrar or its agent; and the


                                     -22-
<PAGE>


Administrative Trustees, or any one of them, and, if executed on behalf of the
Trust by facsimile signature, countersigned by the Transfer Agent and Registrar
or its agent shall make available for delivery, in exchange for or in lieu of
any such mutilated, destroyed, lost or stolen Trust Securities Certificate, a
new Trust Securities Certificate of like class, tenor and denomination. In
connection with the issuance of any new Trust Securities Certificate under this
Section, the Administrative Trustees or the Transfer Agent and Registrar may
require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection therewith. Any duplicate Trust
Securities Certificate issued pursuant to this Section shall constitute
conclusive evidence of an ownership interest in the Trust, as if originally
issued, whether or not the lost, stolen or destroyed Trust Securities
Certificate shall be found at any time.

          SECTION 5.06. PERSONS DEEMED SECURITYHOLDERS. Prior to due
presentation of a Trust Securities Certificate for registration of transfer, the
Trustees and the Transfer Agent and Registrar, and any agent of the Trustee and
the Transfer Agent and Registrar, shall be entitled to treat the Person in whose
name any Trust Securities Certificate shall be registered in the Securities
Register as the owner of such Trust Securities Certificate for the purpose of
receiving Distributions and for all other purposes whatsoever, and neither the
Trustees nor the Transfer Agent and Registrar shall be bound by any notice to
the contrary.

          SECTION 5.07. ACCESS TO LIST OF SECURITYHOLDERS' NAMES AND ADDRESSES.
The Administrative Trustees shall furnish or cause to be furnished (x) to the
Depositor, within 15 days after receipt by any Administrative Trustee of a
request therefor from the Depositor in writing and (y) to the Property Trustee,
promptly after receipt by any Administrative Trustee of a request therefor from
the Property Trustee in writing in order to enable the Property Trustee to
discharge its obligations under this Trust Agreement, a list, in such form as
the Depositor or the Property Trustee may reasonably require, of the names and
addresses of the Securityholders as of a recent date. If Holders of Trust
Securities Certificates evidencing ownership at such time and for the previous
six months not less than 25% of the Outstanding aggregate Liquidation Amount
apply in writing to any Administrative Trustee, and such application states that
the applicants desire to communicate with other Securityholders with respect to
their rights under this Trust Agreement or under the Trust Securities
Certificates and such application is accompanied by a copy of the communication
that such applicants propose to transmit, then the Administrative Trustees
shall, within five Business Days after the receipt of such application, afford
such applicants access during normal business hours to the current list of
Securityholders. Each Holder, by receiving and holding a Trust Securities
Certificate, shall be deemed to have agreed not to hold either the Depositor or
any Trustees accountable by reason of the disclosure of its name and address,
regardless of the source from which such information was derived.

          SECTION 5.08. MAINTENANCE OF OFFICE OR AGENCY. The Depositor shall or
shall cause the Transfer Agent and Registrar to maintain in the Borough of
Manhattan, The City of New York, an office or offices or agency or agencies
where Preferred Trust Securities Certificates may be surrendered for
registration of transfer or exchange and where notices and demands to or upon
the Depositor, the Trust or the Transfer Agent and Registrar in respect of the


                                     -23-
<PAGE>


Trust Securities and the Trust Agreement may be served. The Depositor initially
designates Midwest Clearing Corporation, 40 Broad Street, New York, New York
10004 as its principal office for such purposes. The Depositor shall or shall
cause the Transfer Agent and Registrar to give prompt written notice to the
Depositor, the Property Trustee and to the Securityholders of any change in the
location of the Securities Register or any such office or agency. If at any time
the Depositor shall fail to maintain such office or agency or shall fail to
furnish the Property Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust
Office of the Property Trustee, and the Depositor hereby appoints the Property
Trustee its agent and the agent of the Trust to receive all such presentations,
surrenders, notices and demands.

          SECTION 5.09. APPOINTMENT OF PAYING AGENT. The Paying Agent
shall make distributions to Securityholders from the Payment Account and shall
report the amounts of such distributions to the Administrative Trustees and the
Property Trustee. Any Paying Agent shall have the revocable power to withdraw
funds from the Payment Account for the purpose of making the Distributions
referred to above. The Property Trustee shall be entitled to rely upon a
certificate of the Paying Agent stating in effect the amount of such funds so to
be withdrawn and that same are to be applied by the Paying Agent in accordance
with this Section 5.09. The Administrative Trustees or any one of them may
revoke such power and remove the Paying Agent if the Administrative Trustee or
any one of them determines in its sole discretion that the Paying Agent shall
have failed to perform its obligations under this Trust Agreement in any
material respect. The Paying Agent shall initially be ____________________, and
it may choose any co-paying agent that is acceptable to the Administrative
Trustees and the Depositor. The Paying Agent shall be permitted to resign upon
30 days' written notice to the Administrative Trustees and the Depositor. In the
event of the removal or resignation of ______________________ as Paying Agent,
the Administrative Trustees shall appoint a successor that is reasonably
acceptable to the Property Trustee and the Depositor to act as Paying Agent
(which shall be a bank, trust company or an Affiliate of the Depositor). The
Administrative Trustees shall cause such successor Paying Agent or any
additional Paying Agent appointed by the Administrative Trustees to execute and
deliver to the Trustees an instrument in which such successor Paying Agent or
additional Paying Agent shall agree with the Trustees that as Paying Agent, such
successor Paying Agent or additional Paying Agent will hold all sums, if any,
held by it for payment to the Securityholders in trust for the benefit of the
Securityholders entitled thereto until such sums shall be paid to such
Securityholders. The Paying Agent shall return all unclaimed funds to the
Property Trustee and upon resignation or removal of a Paying Agent such Paying
Agent shall also return all funds in its possession to the Property Trustee. The
provisions of Sections 8.01, 8.03 and 8.06 shall apply to the Paying Agent
appointed hereunder, and the Paying Agent shall be bound by the requirements
with respect to paying agents of securities issued pursuant to the Trust
Indenture Act. Any reference in this Trust Agreement to the Paying Agent shall
include any co-paying agent unless the context requires otherwise.

          SECTION 5.10. OWNERSHIP OF COMMON TRUST SECURITIES BY DEPOSITOR. On
the Closing Date, the Depositor shall acquire, and thereafter retain, beneficial
and record ownership of the Common Trust Securities. Except in connection with a


                                     -24-
<PAGE>


transaction involving the Depositor that would be permitted under Article Eleven
of the Subordinated Indenture, any attempted transfer of the Common Trust
Securities shall be void. The Administrative Trustees shall cause each Common
Trust Securities Certificate issued to the Depositor to contain a legend stating
"THIS CERTIFICATE IS NOT TRANSFERABLE EXCEPT AS PROVIDED IN THE TRUST
AGREEMENT". Common Trust Securities Certificates representing the Common Trust
Securities shall be issued to the Depositor in the form of a typewritten or
definitive Common Trust Securities Certificate.

          SECTION 5.11. DEFINITIVE PREFERRED TRUST SECURITIES CERTIFICATES. Upon
initial issuance of the Preferred Trust Securities, the Definitive Preferred
Trust Securities Certificates shall be typewritten, printed, lithographed or
engraved or may be produced in any other manner as is reasonably acceptable to
the Administrative Trustees, as evidenced by the execution thereof by the
Administrative Trustees, or any one of them. The Administrative Trustees, or any
one of them, shall execute on behalf of the Trust by manual or facsimile
signature, and, if executed by facsimile on behalf of the Trust, countersigned
by the Transfer Agent and Registrar or its agent, the Definitive Preferred Trust
Securities Certificates initially in accordance with the instructions of the
Depositor. Neither the Transfer Agent and Registrar nor any of the
Administrative Trustees shall be liable for any delay in delivery of such
instructions and may conclusively rely on, and shall be protected in relying on,
such instructions.

                  SECTION 5.12. BOOK-ENTRY SYSTEM. Some or all of the Preferred
Trust Securities may be registered in the name of a securities depository
("Securities Depository") or a nominee therefor, and held in the custody of the
Securities Depository or a custodian thereof. In such event, a single
certificate will be issued and delivered to the Securities Depository for such
Preferred Trust Securities, in which case the Owners of such Preferred Trust
Securities will not receive physical delivery of certificates for Preferred
Trust Securities. Except as provided herein, all transfers of beneficial
ownership interests in such Preferred Trust Securities will be made by
book-entry only, and no investor or other party purchasing, selling or otherwise
transferring beneficial ownership of the Preferred Trust Securities will
receive, hold or deliver any certificate for Preferred Trust Securities. The
Depositor, the Trustees and the Paying Agent will recognize the Securities
Depository or its nominee as the Holder of Preferred Trust Securities for all
purposes, including notices and voting.

          The Administrative Trustees, at the direction and expense of the
Depositor, may from time to time appoint a Securities Depository or a successor
thereto and enter into a letter of representations or other agreement with such
Securities Depository to establish procedures with respect to the Preferred
Trust Securities. Any Securities Depository shall be a Clearing Agency.

          The Depositor and the Trustees covenant and agree to meet the
requirements of a Securities Depository for the Preferred Trust Securities with
respect to required notices and other provisions of the letter of
representations or agreement executed with respect to such Preferred Trust
Securities.


                                     -25-
<PAGE>


          Whenever the beneficial ownership of any Preferred Trust Securities is
determined through the books of a Securities Depository, the requirements in
this Trust Agreement of holding, delivering or transferring such Preferred Trust
Securities shall be deemed modified with respect to such Preferred Trust
Securities to meet the requirements of the Securities Depository with respect to
actions of the Trustees, the Depositor and the Paying Agent. Any provisions
hereof permitting or requiring delivery of such Preferred Trust Securities
shall, while such Preferred Trust Securities are in a book-entry system, be
satisfied by the notation on the books of the Securities Depository in
accordance with applicable state law.

          SECTION 5.13. RIGHTS OF SECURITYHOLDERS. The legal title to the Trust
Property is vested exclusively in the Property Trustee (in its capacity as such)
in accordance with Section 2.09, and the Securityholders shall not have any
right or title therein other than an undivided beneficial interest in the assets
of the Trust conferred by their Trust Securities and they shall have no right to
call for any partition or division of property, profits or rights of the Trust
except as described below. The Trust Securities shall be personal property
giving only the rights specifically set forth therein and in this Trust
Agreement. The Preferred Trust Securities shall have no preemptive or similar
rights and when issued and delivered to Securityholders against payment of the
purchase price therefor will be fully paid and nonassessable undivided
beneficial interests in the assets of the Trust.

          SECTION 5.14. CANCELLATION BY TRANSFER AGENT AND REGISTRAR. All Trust
Securities Certificates surrendered for payment, redemption, registration of
transfer or exchange shall, if surrendered to any Person other than the Transfer
Agent and Registrar, be delivered to the Transfer Agent and Registrar and, if
not theretofore canceled, shall be promptly canceled by the Transfer Agent and
Registrar. No Trust Securities Certificates shall be issued in lieu of or in
exchange for any Trust Securities Certificates canceled as provided in this
Section, except as expressly permitted by this Trust Agreement. All canceled
Trust Securities Certificates held by the Transfer Agent and Registrar shall be
disposed of in accordance with customary practices.


                                   ARTICLE VI

                    ACTS OF SECURITYHOLDERS; MEETINGS; VOTING

          SECTION 6.01. LIMITATIONS ON VOTING RIGHTS. (a) Except as provided in
this Section 6.01, in Section 10.03 and as otherwise required by law, no Holder
of Preferred Trust Securities shall have any right to vote or in any manner
otherwise control the administration, operation and management of the Trust or
the obligations of the parties hereto, nor shall anything herein set forth, or
contained in the terms of the Trust Securities Certificates, be construed so as
to constitute the Securityholders from time to time as partners or members of an
association. If the Property Trustee fails to enforce its rights under the
Debentures or this Trust Agreement, a Holder of Preferred Trust Securities may
institute a legal proceeding directly against the Depositor to enforce the
Property Trustee's rights under the Debentures or this Trust Agreement, to the
fullest extent permitted by law, without first instituting any legal proceeding


                                     -26-
<PAGE>


against the Property Trustee or any other Person. Notwithstanding the foregoing,
a Holder of Preferred Trust Securities may directly institute a proceeding for
enforcement of payment to such Holder of principal of or interest on the
Debentures having a principal amount equal to the aggregate liquidation
preference amount of the Preferred Trust Securities of such Holder on or after
the due dates specified in the Debentures.

          (b) So long as any Debentures are held by the Property Trustee, the
Trustees shall not (i) direct the time, method and place of conducting any
proceeding for any remedy available to the Debenture Trustee, or executing any
trust or power conferred on the Debenture Trustee with respect to such
Debentures, (ii) waive any past default which is waivable under Section 813 of
the Subordinated Indenture, (iii) exercise any right to rescind or annul a
declaration that the principal of all the Debentures shall be due and payable or
(iv) consent to any amendment, modification or termination of the Subordinated
Indenture or the Debentures, where such consent shall be required, without, in
each case, obtaining the prior approval of the Holders of at least 66 2/3% of
the aggregate Liquidation Amount of the Outstanding Preferred Trust Securities;
provided, however, that where a consent under the Subordinated Indenture would
require the consent of each Holder of Debentures affected thereby, no such
consent shall be given by any Trustee without the prior written consent of each
Holder of Preferred Trust Securities. The Trustees shall not revoke any action
previously authorized or approved by a vote of the Preferred Trust Securities,
except pursuant to a subsequent vote of the Preferred Trust Securities. The
Property Trustee shall notify all Holders of the Preferred Trust Securities of
any notice of default received from the Debenture Trustee with respect to the
Debentures. In addition to obtaining the foregoing approvals of the Holders of
the Preferred Trust Securities, prior to taking any of the foregoing actions,
the Property Trustee shall, at the expense of the Depositor, obtain an Opinion
of Counsel experienced in such matters to the effect that the Trust will be
classified as a "grantor trust" and not as an association taxable as a
corporation for United States federal income tax purposes on account of such
action.

          (c) If any proposed amendment to the Trust Agreement provides for, or
the Trustees otherwise propose to effect, (i) any action that would materially
adversely affect the powers, preferences or special rights of the Preferred
Trust Securities, whether by way of amendment to the Trust Agreement or
otherwise, or (ii) the dissolution, winding-up or termination of the Trust,
other than pursuant to the terms of this Trust Agreement, then the Holders of
Outstanding Preferred Trust Securities as a class will be entitled to vote on
such amendment or proposal and such amendment or proposal shall not be effective
except with the approval of the Holders of at least 66 2/3% in aggregate
Liquidation Amount of the Outstanding Preferred Trust Securities.

          SECTION 6.02. NOTICE OF MEETINGS. Notice of all meetings of the
Holders of Preferred Trust Securities, stating the time, place and purpose of
the meeting, shall be given by the Administrative Trustees pursuant to Section
10.08 to each Holder of a Preferred Trust Security, at his registered address,
at least 15 days and not more than 90 days before the meeting. At any such
meeting, any business properly before the meeting may be so considered whether


                                     -27-
<PAGE>


or not stated in the notice of the meeting. Any adjourned meeting may be held as
adjourned without further notice.

          SECTION 6.03. MEETINGS OF HOLDERS OF PREFERRED TRUST SECURITIES. No
annual meeting of Securityholders is required to be held. The Administrative
Trustees, however, shall call a meeting of Securityholders to vote on any matter
upon the written request of the Holders of 25% of the then Outstanding Preferred
Trust Securities (based upon their aggregate Liquidation Amount) and may, at any
time in their discretion, call a meeting of Holders of Preferred Trust
Securities to vote on any matters as to which the Holders of Preferred Trust
Securities are entitled to vote.

          Holders of 50% of the then Outstanding Preferred Trust Securities
(based upon their aggregate Liquidation Amount), present in person or by proxy,
shall constitute a quorum at any meeting of Securityholders.

          If a quorum is present at a meeting, an affirmative vote by the
Holders of Preferred Trust Securities present, in person or by proxy, holding
more than the lesser of (x) 66 2/3% of the then Outstanding Preferred Trust
Securities (based upon their aggregate Liquidation Amount) held by the Holders
of then Outstanding Preferred Trust Securities present, either in person or by
proxy, at such meeting and (y) 50% of the Outstanding Preferred Trust Securities
(based upon their aggregate Liquidation Amount) shall constitute the action of
the Securityholders, unless this Trust Agreement requires a greater number of
affirmative votes.

          SECTION 6.04. VOTING RIGHTS. Securityholders shall be entitled to one
vote for each $_____ of Liquidation Amount represented by their Trust Securities
in respect of any matter as to which such Securityholders are entitled to vote.

          SECTION 6.05. PROXIES, ETC. At any meeting of Securityholders,
any Securityholder entitled to vote thereat may vote by proxy, provided that no
proxy shall be voted at any meeting unless it shall have been placed on file
with the Administrative Trustees, or with such other officer or agent of the
Trust as the Administrative Trustees may direct, for verification prior to the
time at which such vote shall be taken. Only Securityholders of record shall be
entitled to vote. When Trust Securities are held jointly by several Persons, any
one of them may vote at any meeting in person or by proxy in respect of such
Trust Securities, but if more than one of them shall be present at such meeting
in person or by proxy, and such joint owners or their proxies so present
disagree as to any vote to be cast, such vote shall not be received in respect
of such Trust Securities. A proxy purporting to be executed by or on behalf of a
Securityholder shall be deemed valid unless challenged at or prior to its
exercise, or, if earlier, until eleven months after it is sent and the burden of
proving invalidity shall rest on the challenger.

          SECTION 6.06. SECURITYHOLDER ACTION BY WRITTEN CONSENT. Any action
which may be taken by Securityholders at a meeting may be taken without a
meeting and without notice if Securityholders holding a majority of all
Outstanding Trust Securities entitled to vote in respect of such action (or such


                                     -28-
<PAGE>


larger proportion thereof as shall be required by any express provision of this
Trust Agreement) shall consent to the action in writing (based upon their
aggregate Liquidation Amount).

          SECTION 6.07. RECORD DATE FOR VOTING AND OTHER PURPOSES. For the
purposes of determining the Securityholders who are entitled to notice of and to
vote at any meeting or to vote by written consent, or to participate in any
Distribution on the Trust Securities in respect of which a record date is not
otherwise provided for in this Trust Agreement, or for the purpose of any other
action, the Administrative Trustees may from time to time fix a date, not more
than 90 days prior to the date of any meeting of Securityholders or the payment
of Distribution or other action including action to be taken by written consent,
as the case may be, as a record date for the determination of the identity of
the Securityholders of record for such purposes.

          SECTION 6.08. ACTS OF SECURITYHOLDERS. Any request, demand,
authorization, direction, notice, consent, waiver or other action provided or
permitted by this Trust Agreement to be given, made or taken by Securityholders
may be embodied in and evidenced by one or more instruments of substantially
similar tenor signed by such Securityholders in person or by an agent duly
appointed in writing; and, except as otherwise expressly provided herein, such
action shall become effective when such instrument or instruments are delivered
to the Administrative Trustees. Such instrument or instruments (and the action
embodied therein and evidenced thereby) are herein sometimes referred to as the
"Act" of the Securityholders signing such instrument or instruments. Proof of
execution of any such instrument or of a writing appointing any such agent shall
be sufficient for any purpose of this Trust Agreement and (subject to Section
8.01) conclusive in favor of the Trustees, if made in the manner provided in
this Section.

          The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgements of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority. The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other manner which any Trustee deems sufficient.

          The ownership of Preferred Trust Securities shall be proved by the
Securities Register.

          Any request, demand, authorization, direction, notice, consent, waiver
or other Act of the Securityholder of any Trust Security shall bind every future
Securityholder of the same Trust Security and the Securityholder of every Trust
Security issued upon the registration of transfer thereof or in exchange
therefor or in lieu thereof in respect of anything done, omitted or suffered to
be done by the Trustees or the Trust in reliance thereon, whether or not
notation of such action is made upon such Trust Security.


                                     -29-
<PAGE>


          Without limiting the foregoing, a Securityholder entitled hereunder to
take any action hereunder with regard to any particular Trust Security may do so
with regard to all or any part of the Liquidation Amount of such Trust Security
or by one or more duly appointed agents each of which may do so pursuant to such
appointment with regard to all or any part of such Liquidation Amount.

          If any dispute shall arise between or among the Securityholders and
the Administrative Trustees with respect to the authenticity, validity or
binding nature of any request, demand, authorization, direction, consent, waiver
or other Act of such Securityholder or Trustee under this Article VI, then the
determination of such matter by the Property Trustee shall be conclusive with
respect to such matter.

          SECTION 6.09. INSPECTION OF RECORDS. Subject to Section 5.07
concerning access to the list of Securityholders, upon reasonable notice to the
Administrative Trustees and the Property Trustee, the other records of the Trust
shall be open to inspection by Securityholders during normal business hours for
any purpose reasonably related to such Securityholder's interest as a
Securityholder.

the Property Trustee's charter or by-laws; and

          (e) the execution, delivery and performance by the Property Trustee of
this Trust Agreement does not require the consent or approval of, the giving of
notice to, or the registration with any Federal or New York banking authority.

          SECTION 7.02. DELAWARE TRUSTEE. The Delaware Trustee represents and
warrants for the benefit of the Depositor and the Securityholders that:

duly incorporated, validly existing and in good standing under the laws of the
State of Delaware;

                                  ARTICLE VIII

                                  THE TRUSTEES

          SECTION 8.01. CERTAIN DUTIES AND RESPONSIBILITIES.

          (a) The duties and responsibilities of the Trustees shall be
restricted to those set forth in the express provisions of this Trust Agreement
and, in the case of the Property Trustee, as provided in the Trust Indenture
Act, and no implied covenants or obligations shall be read into this Trust
Agreement against any of the Trustees. For purposes of Sections 315(a) and
315(c) of the Trust Indenture act, the term "default" is hereby defined as an
Event of Default which has occurred and is continuing. Notwithstanding the


                                     -31-
<PAGE>


foregoing, no provision of this Trust Agreement shall require any of the
Trustees to expend or risk its own funds or otherwise incur any financial
liability in the performance of any of its duties hereunder, or in the exercise
of any of its rights or powers, if it shall have reasonable grounds for
believing that repayment of such funds or adequate indemnity against such risk
or liability is not reasonably assured to it. Notwithstanding anything contained
in this Trust Agreement to the contrary, the duties and responsibilities of the
Property Trustee under this Trust Agreement shall be subject to the protections,
exculpations and limitations on liability afforded to the Property Trustee under
this Trust Agreement, the Trust Indenture Act, the Delaware Business Trust Act
and, to the extent applicable, Rule 3a-7 under the Investment Company Act or any
successor rule thereunder. Whether or not therein expressly so provided, every
provision of this Trust Agreement relating to the conduct or affecting the
liability of or affording protection to the Trustees shall be subject to the
provisions of this Section 8.01.

          (b) All payments made by the Property Trustee or a Paying Agent in
respect of the Trust Securities shall be made only from the income and proceeds
from the Trust Property and only to the extent that there shall be sufficient
income or proceeds from the Trust Property to enable the Property Trustee or
Paying Agent to make payments in accordance with the terms hereof. Each
Securityholder, by its acceptance of a Trust Security, agrees that it will look
solely to the income and proceeds from the Trust Property to the extent
available for distribution to it as herein provided and that the Trustees are
not personally liable to it for any amount distributable in respect of any Trust
Security or for any other liability in respect of any Trust Security. This
Section 8.01(b) does not limit the liability of the Trustees expressly set forth
elsewhere in this Trust Agreement or, in the case of the Property Trustee, in
the Trust Indenture Act.

          (c) All duties and responsibilities of the Property Trustee contained
in this Trust Agreement are subject to the following:

               (i) the Property Trustee's sole duty with respect to the custody,
          safe keeping and physical preservation of the Trust Property shall be
          to deal with such property in a similar manner as the Property Trustee
          deals with similar property for its own account, subject to the
          protections, exculpations and limitations on liability afforded to the
          Property Trustee under this Trust Agreement, the Trust Indenture Act,
          the Delaware Business Trust Act and, to the extent applicable, Rule
          3a-7 under the Investment Company Act or any successor rule
          thereunder;

               (ii) the Property Trustee shall have no duty or liability for or
          with respect to the value, genuineness, existence or sufficiency of
          the Trust Property or the payment of any taxes or assessments levied
          thereon or in connection therewith;

               (iii) the Property Trustee shall not be liable for any interest
          on any money received by it except as it may otherwise agree with the
          Depositor. Money held by the Property Trustee need not be segregated
          from other funds held by it except in relation to the Payment Account


                                     -32-

          established by the Property Trustee pursuant to this Trust Agreement
          and except to the extent otherwise required by law; and

               (iv) the Property Trustee shall not be responsible for monitoring
          the compliance by the Administrative Trustees or the Depositor with
          their respective duties under this Trust Agreement, nor shall the
          Property Trustee be liable for the default or misconduct of the
          Administrative Trustees or the Depositor.

          SECTION 8.02. NOTICE OF DEFAULTS. (a) Within ninety (90) days after
the occurrence of any default known to the Property Trustee, the Property
Trustee shall transmit, in the manner and to the extent provided in Section
10.08, notice of such default to the Securityholders and the Depositor, unless
such default shall have been cured or waived. For the purpose of this Section,
the term "default" means any event which is, or after notice or lapse of time or
both would become, an Event of Default.

               (b) Within five Business Days after receipt of notice of the
Debenture Issuer's exercise of its right to defer the payment of interest on the
Debentures pursuant to the Subordinated Indenture, an Administrative Trustee
shall transmit, in the manner and to the extent provided in Section 10.08,
notice of such exercise to the Securityholders and the Property Trustee.

          SECTION 8.03. CERTAIN RIGHTS OF PROPERTY TRUSTEE. Subject to the
provisions of Section 8.01 and except as provided by law:

               (i) the Property Trustee may rely and shall be protected in
          acting or refraining from acting in good faith upon any resolution,
          Opinion of Counsel, certificate, written representation of a Holder or
          transferee, certificate of auditors or any other certificate,
          statement, instrument, opinion, report, notice, request, direction,
          consent, order, appraisal, bond, debenture, note, other evidence of
          indebtedness or other paper or document reasonably believed by it to
          be genuine and to have been signed or presented by the proper party or
          parties;

               (ii) if (A) in performing its duties under this Trust Agreement
          the Property Trustee is required to decide between alternative courses
          of action or (B) in construing any of the provisions in this Trust
          Agreement the Property Trustee finds the same ambiguous or
          inconsistent with any other provisions contained herein or (C) the
          Property Trustee is unsure of the application of any provision of this
          Trust Agreement, then, except as to any matter as to which the
          Preferred Trust Securityholders are entitled to vote under the terms
          of this Trust Agreement, the Property Trustee shall deliver a notice
          to the Depositor requesting written instructions of the Depositor as
          to the course of action to be taken. The Property Trustee shall take
          such action, or refrain from taking such action, as the Property
          Trustee shall be instructed in writing to take, or to refrain from
          taking, by the Depositor; provided, however, that if the Property


                                     -33-
<PAGE>


          Trustee does not receive such instructions of the Depositor within ten
          Business Days after it has delivered such notice, or such reasonably
          shorter period of time set forth in such notice (which to the extent
          practicable shall not be less than two Business Days), it may, but
          shall be under no duty to, take or refrain from taking such action not
          inconsistent with this Trust Agreement as it shall deem advisable and
          in the best interests of the Securityholders, in which event the
          Property Trustee shall have no liability except for its own bad faith,
          negligence or willful misconduct;

               (iii) whenever in the administration of this Trust Agreement the
          Property Trustee shall deem it desirable that a matter be proved or
          established prior to taking, suffering or omitting any action
          hereunder, the Property Trustee (unless other evidence be herein
          specifically prescribed) may, in the absence of bad faith on its part,
          request and rely upon an Officers' Certificate which, upon receipt of
          such request, shall be promptly delivered by the Depositor or the
          Administrative Trustees;

               (iv) the Property Trustee may consult with counsel of its
          selection and the written advice of such counsel or any Opinion of
          Counsel shall be full and complete authorization and protection in
          respect of any action taken, suffered or omitted by it hereunder in
          good faith and in reliance thereon;

               (v) the Property Trustee shall be under no obligation to exercise
          any of the rights or powers vested in it by this Trust Agreement at
          the request or direction of any Securityholder pursuant to this Trust
          Agreement, unless such Securityholder shall have offered to the
          Property Trustee reasonable security or indemnity against the costs,
          expenses (including reasonable attorneys' fees and expenses) and
          liabilities which might be incurred by it in complying with such
          request or direction;

               (vi) the Property Trustee shall not be bound to make any
          investigation into the facts or matters stated in any resolution,
          certificate, statement, instrument, opinion, report, notice, request,
          direction, consent, order, approval, bond, debenture, note or other
          evidence of indebtedness or other paper or document, but the Property
          Trustee, in its discretion, may make such further inquiry or
          investigation into such facts or matters as it may see fit, and, if
          the Property Trustee shall determine to make such further inquiry or
          investigation, it shall be entitled to examine the books, records and
          premises of the Depositor personally or by agent or attorney;

               (vii) the Property Trustee may execute any of the trusts or
          powers hereunder or perform any duties hereunder either directly or by

          be responsible for any misconduct or negligence on the part of any
          agent or attorney appointed with due care by it hereunder;

<PAGE>


               (viii) the Property Trustee shall not be liable for any action
          taken, suffered, or omitted to be taken by it in good faith and
          reasonably believed by it to be authorized or within the discretion or
          rights or powers conferred upon it by this Trust Agreement;

               (ix) the Property Trustee shall not be charged with knowledge of
          any default or Event of Default with respect to the Trust Securities
          unless either (A) a Responsible Officer of the Property Trustee shall
          have actual knowledge of the default or Event of Default or (B)
          written notice of such default or Event of Default shall have been
          given to the Property Trustee by the Depositor, the Administrative
          Trustees or by any Holder of the Trust Securities;

               (x) no provision of this Trust Agreement shall be deemed to
          impose any duty or obligation on the Property Trustee to perform any
          act or acts or exercise any right, power, duty or obligation conferred
          or imposed on it in any jurisdiction in which it shall be illegal, or
          in which the Property Trustee shall be unqualified or incompetent in
          accordance with applicable law, to perform any such act or acts or to
          exercise any such right, power, duty or obligation; and no permissive
          or discretionary power or authority available to the Property Trustee
          shall be construed to be a duty;

               (xi) no provision of this Trust Agreement shall require the
          Property Trustee to expend or risk its own funds or otherwise incur
          personal financial liability in the performance of any of its duties
          or in the exercise of any of its rights or powers, if the Property
          Trustee shall have reasonable grounds for believing that the repayment
          of such funds or liability is not reasonably assured to it under the
          terms of this Trust Agreement or adequate indemnity against such risk
          or liability is not reasonably assured to it;

               (xii) the Property Trustee shall have no duty to see to any
          recording, filing or registration of any instrument (including any
          financing or continuation statement or any tax or securities form) (or
          any rerecording, refiling or registration thereof);

               (xiii) the Property Trustee shall have the right at any time to
          seek instructions concerning the administration of this Trust
          Agreement from any court of competent jurisdiction; and

               (xiv) whenever in the administration of this Trust Agreement the
          Property Trustee shall deem it desirable to receive instructions with
          respect to enforcing any remedy or right or taking any other action
          hereunder, the Property Trustee (A) may request instructions from the
          Holders of the Trust Securities, which instructions may only be given
          by the Holders of the same Liquidation Amount of the Trust Securities
          as would be entitled to direct the Property Trustee under the terms of


                                     -35-
<PAGE>


          this Trust Agreement in respect of such remedies, rights or actions,
          (B) may refrain from enforcing such remedy or right or taking such
          other action until such instructions are received, and (C) shall be
          protected in acting in accordance with such instructions.

          SECTION 8.04. NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES.
The recitals contained herein and in the Trust Securities Certificates shall be
taken as the statements of the Trust, and the Trustees do not assume any
responsibility for their correctness. The Trustees make no representations as to
the title to, or value or condition of, the property of the Trust or any part
thereof, nor as to the validity or sufficiency of this Trust Agreement, the
Debentures or the Trust Securities. The Trustees shall not be accountable for
the use or application by the Trust of the proceeds of the Trust Securities.

          SECTION 8.05. MAY HOLD SECURITIES. Any Trustee or any agent of any
Trustee or the Trust, in its individual or any other capacity, may become the
owner or pledgee of Trust Securities and, except as provided in the definition
of the term "Outstanding" in Article I, may otherwise deal with the Trust with
the same rights it would have if it were not a Trustee or such agent.

          SECTION 8.06. COMPENSATION; FEES; INDEMNITY.

                  The Depositor agrees:

               (i) to pay to the Trustees from time to time reasonable
          compensation for all services rendered by the Trustees hereunder
          (which compensation shall not be limited by any provision of law in
          regard to the compensation of a trustee of an express trust);

               (ii) except as otherwise expressly provided herein, to reimburse
          the Trustees upon request for all reasonable expenses, disbursements
          and advances reasonably incurred or made by the Trustees in accordance
          with any provision of this Trust Agreement (including the reasonable
          compensation and the expenses and disbursements of its agents and
          counsel), except any such expense, disbursement or advance as may be
          attributable to its negligence (gross negligence, in the case of any
          Administrative Trustee), bad faith or willful misconduct; and

               (iii) to indemnify each Trustee for, and to hold each Trustee
          harmless against, any and all loss, damage, claims, liability or
          expense incurred without negligence (gross negligence, in the case of
          any Administrative Trustee), bad faith or willful misconduct on its
          part, arising out of or in connection with the acceptance or
          administration of the trust or trusts under this Trust Agreement,
          including the reasonable costs and expenses of defending itself
          against any claim or liability in connection with the exercise or
          performance of any of its powers or duties hereunder.


                                     -36-
<PAGE>


          As security for the performance of the obligations of the Depositor
under this Section, each of the Trustees shall have a lien prior to the Trust
Securities upon all property and funds held or collected by such Trustee as
such, except funds held in trust for the payment of Distributions on the Trust
Securities.

          In addition to the rights provided to each Trustee pursuant to the
provisions of the immediately preceding paragraph of this Section 8.06, when a
Trustee incurs expenses or renders services in connection with an Event of
Default resulting from a Bankruptcy Event with respect to the Trust, the
expenses (including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable Federal or State bankruptcy, insolvency or
other similar law.

          The provisions of this Section 8.06 shall survive the termination of
this Trust Agreement.

          SECTION 8.07. CERTAIN TRUSTEES REQUIRED; ELIGIBILITY. (a)
There shall at all times be a Property Trustee hereunder with respect to the
Trust Securities. The Property Trustee shall be a Person that has a combined
capital and surplus of at least $50,000,000. If any such Person publishes
reports of condition at least annually, pursuant to law or to the requirements
of its supervising or examining authority, then for the purposes of this
Section, the combined capital and surplus of such Person shall be deemed to be
its combined capital and surplus as set forth in its most recent report of
condition so published. If at any time the Property Trustee with respect to the
Trust Securities shall cease to be eligible in accordance with the provisions of
this Section, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article VIII.

          (b) There shall at all times be one or more Administrative Trustees
hereunder with respect to the Trust Securities. Each Administrative Trustee
shall be either a natural person who is at least 21 years of age or a legal
entity that shall act through one or more persons authorized to bind such
entity.

          (c) There shall at all times be a Delaware Trustee with respect to the
Trust Securities. The Delaware Trustee shall either be (i) a natural person who
is at least 21 years of age and a resident of the State of Delaware or (ii) a
legal entity with its principal place of business in the State of Delaware that
otherwise meets the requirements of applicable Delaware law and that shall act
through one or more persons authorized to bind such entity.

          SECTION 8.08. CONFLICTING INTERESTS.

          If the Property Trustee has or shall acquire a conflicting interest
within the meaning of the Trust Indenture Act, the Property Trustee shall either
eliminate such interest or resign, to the extent and in the manner provided by,
and subject to the provisions of, the Trust Indenture Act and this Trust
Agreement. The Subordinated Indenture, the Guarantee Agreement, the Indenture
(For Unsecured Debt Securities) dated as of January 1, 1998 of TXU Gas Company


                                     -37-
<PAGE>


to The Bank of New York, as trustee, the Guarantee Agreement, dated as of July
2, 1998 between TXU Gas Company, as guarantor and The Bank of New York, as
trustee, and the Amended and Restated Trust Agreement, dated as of July 2, 1998
between TXU Gas Company, as depositor, The Bank of New York, The Bank of New
York (Delaware), Kirk R. Oliver, Laura Anderson, Kevin Lloyd, Jay Rhodes and
Jackie Harrison, as trustees and the several holders referred to therein, shall
be deemed to be specifically described in this Trust Agreement for the purposes
of clause (i) of the first proviso contained in Section 310(b) of the Trust
Indenture Act.

          SECTION 8.09. CO-TRUSTEES AND SEPARATE TRUSTEE.

          Unless an Event of Default shall have occurred and be continuing, at
any time or times, for the purpose of meeting the legal requirements of the
Trust Indenture Act or of any jurisdiction in which any part of the Trust
Property may at the time be located, the Depositor and the Property Trustee
shall have power to appoint, and upon the written request of the Property
Trustee, the Depositor shall for such purpose join with the Property Trustee in
the execution, delivery, and performance of all instruments and agreements
necessary or proper to appoint, one or more Persons approved by the Property
Trustee either to act as co-trustee, jointly with the Property Trustee, of all
or any part of such Trust Property, or to act as separate trustee of any such
property, in either case with such powers as may be provided in the instrument
of appointment, and to vest in such Person or Persons in the capacity aforesaid,
any property, title, right or power deemed necessary or desirable, subject to
the other provisions of this Section. If the Depositor does not join in such
appointment within 15 days after the receipt by it of a request so to do, or in
case a Debenture Event of Default has occurred and is continuing, the Property
Trustee alone shall have power to make such appointment.

          Should any written instrument from the Depositor be required by any
co-trustee or separate trustee so appointed for more fully confirming to such
co-trustee or separate trustee such property, title, right, or power, any and
all such instruments shall, on request, be executed, acknowledged, and delivered
by the Depositor.

          Every co-trustee or separate trustee shall, to the extent permitted by
law, but to such extent only, be appointed subject to the following terms,
namely:

               (1) The Trust Securities shall be executed and delivered and all
          rights, powers, duties, and obligations hereunder in respect of the
          custody of securities, cash and other personal property held by, or
          required to be deposited or pledged with, the Trustees designated for
          such purpose hereunder, shall be exercised, solely by such Trustees.

               (2) The rights, powers, duties, and obligations hereby conferred
          or imposed upon the Property Trustee in respect of any property
          covered by such appointment shall be conferred or imposed upon and
          exercised or performed by the Property Trustee or by the Property
          Trustee and such co-trustee or separate trustee jointly, as shall be
          provided in the instrument appointing such co-trustee or separate
          trustee, except to the extent that under any law of any jurisdiction


                                     -38-
<PAGE>


          in which any particular act is to be performed, the Property Trustee
          shall be incompetent or unqualified to perform such act, in which
          event such rights, powers, duties, and obligations shall be exercised
          and performed by such co-trustee or separate trustee.

               (3) The Property Trustee at any time, by an instrument in writing
          executed by it, with the written concurrence of the Depositor, may
          accept the resignation of or remove any co-trustee or separate trustee
          appointed under this Section 8.09, and, in case a Debenture Event of
          Default has occurred and is continuing, the Property Trustee shall
          have power to accept the resignation of, or remove, any such
          co-trustee or separate trustee without the concurrence of the
          Depositor. Upon the written request of the Property Trustee, the
          Depositor shall join with the Property Trustee in the execution,
          delivery, and performance of all instruments and agreements necessary
          or proper to effectuate such resignation or removal. A successor to
          any co-trustee or separate trustee so resigned or removed may be
          appointed in the manner provided in this Section.

               (4) No co-trustee or separate trustee hereunder shall be
          personally liable by reason of any act or omission of any Trustee, or
          any other such trustee hereunder.

               (5) The Property Trustee shall not be liable by reason of any act
          of a co-trustee or separate trustee hereunder.

               (6) Any Act of Holders delivered to the Property Trustee shall be
          deemed to have been delivered to each such co-trustee and separate
          trustee.

          SECTION 8.10. RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR. No
resignation or removal of any Trustee (as the case may be, the "Relevant
Trustee") and no appointment of a successor Relevant Trustee pursuant to this
Article shall become effective until the acceptance of appointment by the
successor Relevant Trustee in accordance with the applicable requirements of
Section 8.11.

          The Relevant Trustee may resign at any time by giving written notice
thereof to the Securityholders. If the instrument of acceptance by a successor
Relevant Trustee required by Section 8.11 shall not have been delivered to the
resigning Relevant Trustee within 30 days after the giving of such notice of
resignation, the resigning Relevant Trustee may petition any court of competent
jurisdiction for the appointment of a successor Relevant Trustee.

          Unless a Debenture Event of Default shall have occurred and be
continuing, the Relevant Trustee may be removed at any time by Act of the Common
Trust Securityholder. If a Debenture Event of Default shall have occurred and be
continuing, the Relevant Trustee may be removed at such time by Act of the
Securityholders of a majority of the aggregate Liquidation Amount of the
Outstanding Preferred Trust Securities, delivered to the Relevant Trustee (in
its individual capacity and on behalf of the Trust).


                                     -39-
<PAGE>


          If the Relevant Trustee shall resign, be removed or become incapable
of continuing to act as Relevant Trustee at a time when no Debenture Event of
Default shall have occurred and be continuing, the Common Trust Securityholder,
by Act of the Common Trust Securityholder delivered to the retiring Relevant
Trustee, shall promptly appoint a successor Relevant Trustee or Trustees, and
the retiring Relevant Trustee shall comply with the applicable requirements of
Section 8.11. If the Relevant Trustee shall resign, be removed or become
incapable of continuing to act as the Relevant Trustee at a time when a
Debenture Event of Default shall have occurred and be continuing, the Preferred
Trust Securityholders, by Act of the Preferred Trust Securityholders of a
majority in aggregate Liquidation Amount of the Outstanding Preferred Trust
Securities delivered to the retiring Relevant Trustee, shall promptly appoint a
successor Relevant Trustee or Trustees, and the Relevant Trustee shall comply
with the applicable requirements of Section 8.11. If no successor Relevant
Trustee shall have been so appointed by the Common Trust Securityholders or the
Preferred Trust Securityholders and accepted appointment in the manner required
by Section 8.11, any Securityholder who has been a Securityholder of Trust
Securities for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the
appointment of a successor Relevant Trustee.

          The retiring Property Trustee shall give notice of its resignation and
its removal and an appointment of a successor Trustee to all Securityholders in
the manner provided in Section 10.08 and shall give notice to the Depositor.
Such notice shall include the address of its Corporate Trust Office.

          Notwithstanding the foregoing or any other provision of this Trust
Agreement, in the event any Administrative Trustee or a Delaware Trustee who is
a natural person dies or becomes incompetent or incapacitated, the vacancy
created by such death, incompetence or incapacity may be filled by (i) the
unanimous act of remaining Administrative Trustees if there are at least two of
them or (ii) otherwise by the Depositor (with the successor in each case being
an individual who satisfies the eligibility requirements for Administrative
Trustees or Delaware Trustee, as the case may be, set forth in Section 8.07).
Additionally, notwithstanding the foregoing or any other provision of this Trust
Agreement, in the event the Depositor reasonably believes that any
Administrative Trustee who is a natural person has become incompetent or
incapacitated, the Depositor, by notice to the remaining Trustees, may terminate
the status of such Person as an Administrative Trustee (in which case the
vacancy so created will be filled in accordance with the preceding sentence).

          No Property Trustee or Delaware Trustee shall be liable for the acts
or omissions to act of any successor Property Trustee or Delaware Trustee.

          SECTION 8.11. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR. In case of the
appointment hereunder of a successor Relevant Trustee, the retiring Relevant
Trustee and each successor Trustee shall execute and deliver an amendment hereto
wherein each successor Relevant Trustee shall accept such appointment and which
(1) shall contain such provisions as shall be necessary or desirable to transfer
and confirm to, and to vest in, each successor Relevant Trustee all the rights,


                                     -40-
<PAGE>


powers, trusts and duties of the retiring Relevant Trustee and (2) shall add to
or change any of the provisions of this Trust Agreement as shall be necessary to
provide for or facilitate the administration of the trusts hereunder by more
than one Relevant Trustee, it being understood that nothing herein or in such
amendment shall constitute such Relevant Trustees co-trustees of the same trust
and that each such Relevant Trustee shall be trustee of a trust or trusts
hereunder separate and apart from any trust or trusts hereunder administered by

amendment the resignation or removal of the retiring Relevant Trustee shall
become effective to the extent provided therein and each such successor Relevant
Trustee, without any further act, deed or conveyance, shall become vested with
all the rights, powers, trusts and duties of the retiring Relevant Trustee; but,
on request of the Trust or any successor Relevant Trustee such retiring Relevant
Trustee shall duly assign, transfer and deliver to such successor Trustee all
Trust Property, all proceeds thereof and money held by such retiring Relevant
Trustee hereunder with respect to the Trust Securities and the Trust.

          Upon request of any such successor Relevant Trustee, the retiring

such Relevant Trustee hereunder, provided such Person shall be otherwise
qualified and eligible under this Article VIII, without the execution or filing
of any paper, the giving of any notice or any further act on the part of any of
the parties hereto.

          SECTION 8.13. PREFERENTIAL COLLECTION OF CLAIMS AGAINST DEPOSITOR OR
TRUST. If and when the Property Trustee shall be or become a creditor of the

          (b) A copy of each such report shall, at the time of such transmission
to Holders, be filed by the Property Trustee with each stock exchange upon which
the Trust Securities are listed, with the Commission and with the Depositor. The
Depositor will notify the Property Trustee when any Trust Securities are listed
on any stock exchange.

          SECTION 8.15. REPORTS TO THE PROPERTY TRUSTEE. The Depositor and the
Administrative Trustees on behalf of the Trust shall provide to the Property
Trustee such documents, reports and information, if any, and the compliance
certificate required by Section 314 of the Trust Indenture Act, in the form, in
the manner and at the times required by Section 314 of the Trust Indenture Act.
Delivery of such reports, information and documents by the Depositor to the
Property Trustee is for informational purposes only and the Property Trustee's
receipt of such shall not constitute constructive notice of any information
contained therein or determinable from information contained therein, including
the Depositor's compliance with any of its covenants hereunder (as to which the
Property Trustee is entitled to rely exclusively on Officers' Certificates).

          SECTION 8.16. EVIDENCE OF COMPLIANCE WITH CONDITIONS PRECEDENT. Each
of the Depositor and the Administrative Trustees on behalf of the Trust shall

precedent, if any, provided for in this Trust Agreement (including any covenants

the matters set forth in Section 314(c) of the Trust Indenture Act. Any

Certificate.

          SECTION 8.17. NUMBER OF TRUSTEES.

          (a) The number of Trustees shall be seven, provided that Depositor, by
written instrument, may increase or decrease the number of Administrative
Trustees.

number of Trustees is increased pursuant to Section 8.17(a), a vacancy shall
occur. The vacancy shall be filled with a Trustee appointed in accordance with
Section 8.10.

          (c) The death, resignation, retirement, removal, bankruptcy,
incompetence or incapacity to perform the duties of a Trustee shall not operate
to annul, dissolve or terminate the Trust. Whenever a vacancy in the number of
Administrative Trustees shall occur, until such vacancy is filled by the
appointment of an Administrative Trustee in accordance with Section 8.10, the
Administrative Trustees in office, regardless of their number (and
notwithstanding any other provision of this Agreement), shall have all the
powers granted to the Administrative Trustees and shall discharge all the duties
imposed upon the Administrative Trustees by this Trust Agreement.

          SECTION 8.18. DELEGATION OF POWER.

          (a) Any Administrative Trustee may, by power of attorney consistent
with applicable law, delegate to any other natural person over the age of 21 his
or her power for the purpose of executing any documents contemplated in Sections
2.07(a) and 2.07(c), including any registration statement or amendment thereto
filed with the Commission, or making any other governmental filing; and

          (b) the Administrative Trustees shall have power to delegate from time
to time to such of their number the doing of such things and the execution of
such instruments either in the name of the Trust or the names of the
Administrative Trustees or otherwise as the Administrative Trustees may deem
expedient, to the extent such delegation is not prohibited by applicable law or
contrary to the provisions of the Trust, as set forth herein.

          SECTION 8.19. FIDUCIARY DUTY.

          (a) To the extent that, at law or in equity, an Indemnified Person has
duties (including fiduciary duties) and liabilities relating thereto to the
Trust or to any other Covered Person, an Indemnified Person acting under this
Trust Agreement shall not be liable to the Trust or to any other Covered Person
for its good faith reliance on the provisions of this Trust Agreement. The
provisions of this Trust Agreement, to the extent that they restrict the duties
and liabilities of an Indemnified Person otherwise existing at law or in equity
(other than the duties imposed on the Property Trustee under the Trust Indenture
Act), are agreed by the parties hereto to replace such other duties and
liabilities of such Indemnified Person;

          (b) Unless otherwise expressly provided herein and subject to the
provisions of the Trust Indenture Act:

               (i) whenever a conflict of interest exists or arises between an
          Indemnified Person and any Covered Person; or

               (ii) whenever this Trust Agreement or any other agreement
          contemplated herein or therein provides that an Indemnified Person
          shall act in a manner that is, or provides terms that are, fair and
          reasonable to the Trust or any Holder of Trust Securities, the
          Indemnified Person shall resolve such conflict of interest, take such
          action or provide such terms, considering in each case the relative
          interest of each party (including its own interest) to such conflict,
          agreement, transaction or situation and the benefits and burdens
          relating to such interests, any customary or accepted industry
          practices, and any applicable generally accepted accounting practices
          or principles. In the absence of bad faith by the Indemnified Person,
          the resolution, action or term so made, taken or provided by the


                                     -43-
<PAGE>


          Indemnified Person shall not constitute a breach of this Trust
          Agreement or any other agreement contemplated herein or of any duty or
          obligation of the Indemnified Person at law or in equity or otherwise;
          and

          (c) Unless otherwise expressly provided herein and subject to the
provisions of the Trust Indenture Act, whenever in this Trust Agreement an
Indemnified Person is permitted or required to make a decision

               (i) in its "discretion" or under a grant of similar authority,
          the Indemnified Person shall be entitled to consider such interests
          and factors as it reasonably desires, including its own interests, and
          shall have no duty or obligation to give any consideration to any
          interest of or factors affecting the Trust or any other Person; or

               (ii) in its "good faith" or under another express standard, the
          Indemnified Person shall act under such express standard and shall not
          be subject to any other or different standard imposed by this Trust
          Agreement or by applicable law.


                                   ARTICLE IX

                           TERMINATION AND LIQUIDATION

          SECTION 9.01. DISSOLUTION UPON EXPIRATION DATE. The Trust shall
automatically dissolve on December 31, 2040 (the "Expiration Date") and the
Trustees shall take such action as is required by Section 9.04.

          SECTION 9.02. EARLY TERMINATION. Upon the first to occur of any of the
following events (such first occurrence, an "Early Termination Event"):

               (i) the occurrence of a Bankruptcy Event in respect of, or the
          dissolution or liquidation of, the Depositor/Debenture Issuer;

               (ii) the redemption of all of the Preferred Trust Securities;

               (iii) an order for judicial dissolution of the Trust having been
          entered by a court of competent jurisdiction;

               (iv) the election by the Depositor to dissolve the Trust and,
          after satisfaction of liabilities to creditors of the Trust,
          distribute the Debentures to the Holders of Preferred Trust Securities
          in liquidation of the Trust;

the Trust shall dissolve and the Trustees shall take such action as is required
by Section 9.04.


                                     -44-
<PAGE>



          SECTION 9.03. TERMINATION. The respective obligations and
responsibilities of the Trust and the Trustees created hereby shall terminate
upon the latest to occur of the following: (i) the distribution by the Property
Trustee to Securityholders upon the liquidation of the Trust pursuant to Section
9.04, or upon the redemption of all of the Trust Securities pursuant to Section
4.02 or 9.04(d), of all amounts required to be distributed hereunder upon the
final payment of the Trust Securities; (ii) the payment of any expenses owed by
the Trust; and (iii) the discharge of all administrative duties of the
Administrative Trustees, including the performance of any tax reporting
obligations with respect to the Trust or the Securityholders.

          SECTION 9.04. LIQUIDATION. (a) Upon the Expiration Date or if an Early
Termination Event specified in clause (i), (iii) or (iv) of Section 9.02 occurs,
after satisfaction of creditors of the Trust, if any, as provided by applicable
law, the Trust shall be liquidated by the Property Trustee as expeditiously as
the Property Trustee determines to be appropriate by distributing to each
Securityholder a Like Amount of Debentures, subject to Section 9.04(e). Notice
of liquidation shall be given by the Administrative Trustees by first-class
mail, postage prepaid, mailed not later than 30 nor more than 60 days prior to
the Liquidation Date to each Holder of Trust Securities at such Holder's address
appearing in the Securities Register. All notices of liquidation shall:

               (i) state the Liquidation Date;

               (ii) state that from and after the Liquidation Date, the Trust
          Securities will no longer be deemed to be outstanding and any Trust
          Securities Certificates not surrendered for exchange will be deemed to
          represent a Like Amount of Debentures; and

               (iii) provide such information with respect to the mechanics by
          which Holders may exchange Trust Securities Certificates for
          Debentures, or, if Section 9.04(e) applies, receive a Liquidation
          Distribution, as the Administrative Trustees or the Property Trustee
          shall deem appropriate.

          (b) Except where Sections 9.02(ii), 9.04(d) or 9.04(e) apply, in order
to effect the liquidation of the Trust hereunder, and any resulting distribution
of the Debentures to Securityholders, the Property Trustee shall establish a
record date for such distribution (which shall be not more than 45 days prior to
the Liquidation Date) and, either itself acting as exchange agent or through the
appointment of a separate exchange agent, shall establish such procedures as it
shall deem appropriate to effect the distribution of Debentures in exchange for
the Outstanding Trust Securities Certificates.

          (c) Except where Sections 9.02(ii), 9.04(d) or 9.04(e) apply, after
any Liquidation Date, (i) the Trust Securities will no longer be deemed to be
Outstanding, (ii) certificates representing a Like Amount of Debentures will,
after satisfaction of liabilities to creditors of the Trust, if any, as provided
by applicable law, be issued to Holders of Trust Securities Certificates, upon
surrender of such Trust Securities Certificates to the Administrative Trustees


                                     -45-
<PAGE>


or their agent for exchange, (iii) any Trust Securities Certificates not so
surrendered for exchange will be deemed to represent a Like Amount of
Debentures, accruing interest at the rate provided for in the Debentures from
the last Distribution Date on which a Distribution was made on such Trust
Securities Certificates until such Trust Securities Certificates are so
surrendered (and until such Trust Securities Certificates are so surrendered, no
payments or interest or principal will be made to Holders of Trust Securities
Certificates with respect to such Debentures) and (iv) all rights of
Securityholders holding Trust Securities will cease, except the right of such
Securityholders to receive, after satisfaction of liabilities to creditors of
the Trust, if any, as provided by applicable law, Debentures upon surrender of
Trust Securities Certificates.

          (d) If at any time, a Tax Event shall occur and be continuing, and
either (i) in the opinion of counsel to the Depositor experienced in such
matters, there would in all cases, after effecting the dissolution of the Trust,
after satisfaction of liabilities to creditors of the Trust, if any, as provided
by applicable law, and the distribution of the Debentures to the Holders of the
Preferred Trust Securities in exchange therefor, be more than an insubstantial
risk that an Adverse Tax Consequence would continue to exist or (ii) the
Debentures are not held by the Trust, then the Depositor shall have the right to
redeem the Debentures, in whole but not in part, at any time within 90 days
following the occurrence of the Tax Event. Whether or not a Tax Event has
occurred, the Depositor has the right, at any time, to dissolve the Trust and,
after satisfaction of liabilities to creditors of the Trust, if any, as provided
by applicable law, cause the Debentures to be distributed to the Holders of the
Preferred Trust Securities and Common Trust Securities in liquidation of the
Trust on a pro rata basis.

          (e) In the event that, notwithstanding the other provisions of this
Section 9.04, whether because of an order for dissolution entered by a court of
competent jurisdiction or otherwise, distribution of the Debentures in the
manner provided herein is determined by the Property Trustee not to be
practical, the Trust Property shall be liquidated, and the Trust shall be
wound-up, by the Property Trustee in such manner as the Property Trustee
determines. In such event, Securityholders will be entitled to receive out of
the assets of the Trust available for distribution to Securityholders, after
satisfaction of liabilities to creditors of the Trust, if any, as provided by
applicable law, an amount equal to the Liquidation Amount per Trust Security
plus accumulated and unpaid Distributions thereon to the date of payment (such
amount being the "Liquidation Distribution"). If, upon any such winding up, the
Liquidation Distribution can be paid only in part because the Trust has
insufficient assets available to pay in full the aggregate Liquidation
Distribution, then, subject to the next succeeding sentence, the amounts payable
by the Trust on the Trust Securities shall be paid on a pro rata basis (based
upon Liquidation Amounts). The Holder of Common Trust Securities will be
entitled to receive Liquidation Distributions upon any such winding-up pro rata
(determined as aforesaid) with Holders of Preferred Trust Securities, except
that, if a Debenture Event of Default has occurred and is continuing or if a
Debenture Event of Default has not occurred solely by reason of a requirement
that time lapse or notice be given, the Preferred Trust Securities shall have a
priority over the Common Trust Securities.

irrevocably and unconditionally guarantees to each Person to whom the Trust is
now or hereafter becomes indebted or liable (the "Beneficiaries"), and agrees to
assume liability for, the full payment, when and as due, of any and all
Obligations (as hereinafter defined) to such Beneficiaries. As used herein,

other than obligations of the Trust to pay to Holders the amounts due such
Holders pursuant to the terms of the Preferred Trust Securities. This guarantee
and assumption is intended to be for the benefit, of, and to be enforceable by,
all such Beneficiaries, whether or not such Beneficiaries have received notice
hereof.

          SECTION 10.02. LIMITATION OF RIGHTS OF SECURITYHOLDERS. The death,
incapacity, bankruptcy, dissolution or termination of any Person having an
interest, beneficial or otherwise, in a Trust Security shall not operate to
terminate this Trust Agreement, nor dissolve, terminate or annul the Trust, nor
entitle the legal representatives or heirs of such Person or any Securityholder
for such Person, to claim an accounting, take any action or bring any proceeding
in any court for a partition or winding up of the arrangements contemplated
hereby, nor otherwise affect the rights, obligations and liabilities of the
parties hereto or any of them.

          SECTION 10.03. AMENDMENT.

          (a) This Trust Agreement may be amended from time to time by the Trust

or supplement any provision herein or therein which may be inconsistent with any
other provision herein or therein, or to make any other provisions with respect
to matters or questions arising under this Trust Agreement, (ii) to change the
name of the Trust or (iii) to modify, eliminate or add to any provisions of this
Trust Agreement to such extent as shall be necessary to ensure that the Trust
will not be classified for United States federal income tax purposes other than

time that any Trust Securities are outstanding or to ensure the Trust's
exemption from the status of an "investment company" under the Investment
Company Act; provided, however, that such action shall not adversely affect in
any material respect the interests of any Securityholder and, in the case of
clause (i), any such amendments of this Trust Agreement shall become effective
when notice thereof is given to the Securityholders.

          (b) Except as provided in Sections 6.01(c) and 10.03(c), any provision
of this Trust Agreement may be amended by the Administrative Trustees and the
Depositor with (i) the consent of Holders of Trust Securities representing not
less than a majority (based upon Liquidation Amounts) of the outstanding Trust
Securities and (ii) receipt by the Trustees of an Opinion of Counsel to the


                                     -47-
<PAGE>


effect that such amendment or the exercise of any power granted to the Trustees
in accordance with such amendment will not affect the Trust's status as a
grantor trust for federal income tax purposes or the Trust's exemption from
status as an "investment company" under the Investment Company Act.

          (c) In addition to and notwithstanding any other provision in this
Trust Agreement, without the consent of each affected Securityholder, this Trust
Agreement may not be amended to (i) adversely change the amount or timing of any
Distribution on the Trust Securities or otherwise adversely affect the amount of
any Distribution required to be made in respect of the Trust Securities as of a
specified date or (ii) restrict the right of a Securityholder to institute suit
for the enforcement of any such payment on or after such date.

          (d) Notwithstanding any other provisions of this Trust Agreement, no
amendment to this Trust Agreement may be made if, as a result of such amendment,
the Trust would not be classified as a "grantor trust" but an association
taxable as a corporation for United States federal income tax purposes or would
to fail or cease to qualify for the exemption from status of an "investment
company" under the Investment Company Act afforded by Rule 3a-5 thereunder.

          (e) Notwithstanding anything in this Trust Agreement to the contrary,
without the consent of the Depositor and the Trustees, this Trust Agreement may
not be amended in a manner which imposes any additional obligation on the
Depositor or any Trustee or, in the case of the Trustees, which affects any of
their respective rights, duties or immunities hereunder.

            (f) In the event that any amendment to this Trust Agreement is made,
the Administrative Trustees shall promptly provide to the Depositor a copy of
such amendment.

          (g) The Property Trustee and the Delaware Trustee may join in the
execution of any amendment to the Trust Agreement and are entitled to rely upon
an Opinion of Counsel as conclusive evidence that any amendment to this Trust
Agreement entered into pursuant to this Section 10.03 is authorized or permitted
by, and conforms to, the terms of this Section 10.03, has been duly authorized
by and lawfully executed and delivered on behalf of the other requisite parties,
and that it is proper for the Property Trustee under the provisions of this
Section 10.03 to accept the additional trusts created thereby and, if so
requested, for the Property Trustee or the Delaware Trustee to join in the
execution thereof.

          SECTION 10.04. SEPARABILITY. In case any provision in this Trust
Agreement or in the Trust Securities Certificates shall be invalid, illegal or
unenforceable, the validity, legality and enforceability of the remaining
provisions shall not in any way be affected or impaired thereby.

                    Prior to the termination of any such Extension Period,
                    the Company may further extend the interest payment
                    period, provided that such Extension Period together
                    with all such previous and further extensions thereof
                    shall not exceed 20 consecutive quarterly periods at
                    any one time or extend beyond the Maturity of the
                    Debentures of the       Series.  Any Extension Period

                    securities with terms substantially the same as the
                    Preferred Trust Securities.  Upon the termination of
                    any such Extension Period and the payment of all
                    amounts then due, including interest on deferred
                    interest payments, the Company may elect to begin a new
                    Extension Period, subject to the above requirements.
                    No interest shall be due and payable during an
                    Extension Period, except at the end thereof.  The
                    Company will give the Trust and the Trustee notice of

                    earlier of (i) one Business Day prior to the record
                    date for the distribution which would occur but for
                    such election or (ii) the date the Company is required
                    to give notice to any securities exchange on which the
                    Debentures of the      Series may be listed or any

                    notice of such election to the holders of Preferred
                    Trust Securities;

               10.  At any time, the Company will have the right to
                    dissolve the Trust and, after satisfaction of
                    liabilities to creditors, if any, of the Trust as
                    provided by applicable law, cause the Debentures of the
                          Series to be distributed to the holders of the
                    -----
                    Preferred Trust Securities;

               11.  So long as any Securities are outstanding under the
                    Indenture, the Company shall not make any Restricted
                    Payments at any time the Company is in default under
                    the Guarantee with respect to the Trust or is in
                    default with respect to payments due on any Outstanding
                    Securities;

               12.  In the event that, at any time subsequent to the
                    initial authentication and delivery of the Debentures
                    of the       Series, the Debentures of the _____ Series

                    with the exchange or transfer;

                    money, if any, or additional Government Obligations
                    (meeting the requirements of Section 701), if any, or
                    any combination thereof, at such time or times, as
                    shall be necessary, together with the money and/or

                    with and subject to the provisions of said Section 701;
                    provided, however, that such instrument may state that
                    the obligation of the Company to make additional
                    deposits as aforesaid shall be subject to the delivery

                    Company's indebtedness in respect thereof and will be
                    subject to United States federal income tax on the same
                    amounts, at the same times and in the same manner as if
                    such satisfaction and discharge had not been effected;

          of   % per annum, plus Additional Interest, if any, until the
             --
          principal hereof is paid or made available for payment.  The
          amount of interest payable on any Interest Payment Date shall be
          computed on the basis of a 360-day year of twelve 30-day months
          and for any period shorter than a full month, on the basis of the

          the Regular Record Date for such interest, which shall be the
          fifteenth day (whether or not a Business Day) preceding such
          Interest Payment Date.  Any such interest not so punctually paid
          or duly provided for will forthwith cease to be payable to the
          Holder on such Regular Record Date and may either be paid to the
          Person in whose name this Security (or one or more Predecessor
          Securities) is registered at the close of business on a Special
          Record Date for the payment of such Defaulted Interest to be
          fixed by the Trustee, notice whereof shall be given to Holders of
          Securities of this series not less than 10 days prior to such
          Special Record Date, or be paid at any time in any other lawful
          manner not inconsistent with the requirements of any securities
          exchange on which the Securities of this series may be listed,
          and upon such notice as may be required by such exchange, all as
          more fully provided in the Indenture.

          interest on this Security will be made at the office or agency of
          the Company maintained for that purpose in The City of New York,
          the State of New York, in such coin or currency of the United
          States of America as at the time of payment is legal tender for
          payment of public and private debts, provided, however, that, at
          the option of the Company, interest on this Security may be paid
          by check mailed to the address of the person entitled thereto, as
          such address shall appear on the Security Register.

                    Reference is hereby made to the further provisions of
          this Security set forth on the reverse hereof, which further
          provisions shall for all purposes have the same effect as if set
          forth at this place.

          been executed by the Trustee referred to on the reverse hereof by
          manual signature, this Security shall not be entitled to any
          benefit under the Indenture or be valid or obligatory for any

          Holders of the Securities and of the terms upon which the
          Securities are, and are to be, authenticated and delivered.  This
          Security is one of the series designated on the face hereof,
          limited in aggregate principal amount to $           .
                                                    -----------

                    This Security will be redeemable at the option of the
          Company on or after       ,     , at any time in whole and from
                              ------  ----
          time to time in part, upon not less than 30 nor more than 60
          days' notice given as provided in the Indenture, at a Redemption
          Price equal to 100% of the principal amount thereof plus accrued
          and unpaid interest hereon, including Additional Interest, if
          any, to the Redemption Date.

                    If at any time a Tax Event (as defined below) shall
          occur and be continuing and either (i) in the opinion of counsel
          to the Company experienced in such matters, there would in all
          cases, after effecting the dissolution of the Trust, after
          satisfaction of liabilities to creditors of the Trust, if any, as
          provided by applicable law, and the distribution of this Security
          to the holders of the Preferred Securities of the Trust (the
          "Preferred Trust Securities"), in exchange therefor, be more
          than an insubstantial risk that an Adverse Tax Consequence (as
          defined below) would continue to exist or (ii) this Security is
          not held by The Bank of New York as the Property Trustee of [Name
          of Trust], a Delaware statutory business trust (the "Trust") for
          the benefit of the Trust, then the Company shall have the right
          to redeem this Security, in whole but not in part, at any time
          within 90 days following the occurrence of the Tax Event, at 100%
          of the principal amount thereof plus accrued and unpaid interest
          hereon, including Additional Interest, if any, to the Redemption
          Date.

                    "Tax Event" means the receipt by the Trust or the
          Company of an opinion of counsel experienced in such matters to
          the effect that, as a result of (a) any amendment to,
          clarification of, or change (including any announced prospective
          change) in, the laws or treaties (or any regulations thereunder)
          of the United States or any political subdivision or taxing
          authority thereof or therein affecting taxation, (b) any judicial
          decision or any official administrative pronouncement, ruling,
          regulatory procedure, notice or announcement (including any
          notice or announcement of intent to issue or adopt any such
          administrative pronouncement, ruling, regulatory procedure or
          regulation) (each, an "Administrative Action"), or (c) any
          amendment to, clarification of, or change in the official
          position or the interpretation of any such Administrative Action
          or judicial decision or any interpretation or pronouncement that
          provides for a position with respect to such Administrative
          Action or judicial decision that differs from the theretofore
          generally accepted position, in each case by any legislative
          body, court, governmental authority or regulatory body,
          irrespective of the time or manner in which such amendment,
          clarification or change is introduced or made known, which
          amendment, clarification, or change is effective, which
          Administrative Action is taken or which judicial decision is
          issued, in each case on or after the date of issuance of the
          Preferred Trust Securities, there is more than an insubstantial
          risk that (i) the Trust is, or will be, subject to United States
          federal income tax with respect to interest received on this
          Security, (ii) interest payable by the Company on this Security
          is not, or will not be, fully deductible by the Company for
          United States federal income tax purposes, or (iii) the Trust is,
          or will be, subject to more than a de minimis amount of other
          taxes, duties or other governmental charges (each of the
          circumstances described in clauses (i), (ii) or (iii) being an
          "Adverse Tax Consequence").

                    Interest installments whose Stated Maturity is on or
          prior to such Redemption Date will be payable to the Holder of
          such Security, or one or more Predecessor Securities, of record
          at the close of business on the related Regular Record Date
          referred to on the face hereof, all as provided in the Indenture.

                    In the event of redemption of this Security in part
          only, a new Security or Securities of this series and of like
          tenor for the unredeemed portion hereof will be issued in the
          name of the Holder hereof upon the cancellation hereof.

                    The indebtedness evidenced by this Security is, to the
          extent provided in the Indenture, subordinated and subject in
          right of payment to the prior payment in full of all Senior
          Indebtedness, and this Security is issued subject to the
          provisions of the Indenture with respect thereto.  Each Holder of
          this Security, by accepting the same, (a) agrees to and shall be
          bound by such provisions, (b) authorizes and directs the Trustee
          on his behalf to take such action as may be necessary or
          appropriate to acknowledge or effectuate the subordination so
          provided and (c) appoints the Trustee his attorney-in-fact for
          any and all such purposes.  Each Holder hereof, by his acceptance
          hereof, hereby waives all notice of the acceptance of the
          subordination provisions contained herein and in the Indenture by
          each holder of Senior Indebtedness, whether now outstanding or
          hereafter incurred, and waives reliance by each such Holder upon
          said provisions.

                    The Indenture contains provisions for defeasance at any
          time of the entire  indebtedness of this Security upon compliance
          with certain conditions set forth in the Indenture.

                    If an Event of Default with respect to Securities of
          this series shall occur and be continuing, the principal of the
          Securities of this series may be declared due and payable in the
          manner and with the effect provided in the Indenture.

                    The Indenture permits, with certain exceptions as
          therein provided, the amendment thereof and the modification of
          the rights and obligations of the Company and the rights of the
          Holders of the Securities of each series to be affected under the
          Indenture at any time by the Company and the Trustee with the
          consent of the Holders of a majority in principal amount of the
          Securities at the time Outstanding of all series to be affected.
          The Indenture contains provisions permitting the Holders of a
          majority in aggregate principal amount of the Securities of all
          series then Outstanding to waive compliance by the Company with
          certain provisions of the Indenture.  The Indenture also contains
          provisions permitting the Holders of specified percentages in
          principal amount of the Securities of each series at the time
          Outstanding, on behalf of the Holders of all Securities of such
          series, to waive compliance by the Company with certain
          provisions of the Indenture and certain past defaults under the
          Indenture and their consequences.  Any such consent or waiver by
          the Holder of this Security shall be conclusive and binding upon
          such Holder and upon all future Holders of this Security and of
          any Security issued upon the registration of transfer hereof or
          in exchange herefor or in lieu hereof, whether or not notation of
          such consent or waiver is made upon this Security.

                    As provided in and subject to the provisions of the
          Indenture, the Holder of this Security shall not have the right
          to institute any proceeding with respect to the Indenture or for
          the appointment of a receiver or trustee or for any other remedy
          thereunder, unless such Holder shall have previously given the
          Trustee written notice of a continuing Event of Default with
          respect to the Securities of this series, the Holders of not less
          than a majority in aggregate principal amount of the Securities
          of all series at the time Outstanding in respect of which an
          Event of Default shall have occurred and be continuing shall have
          made written request to the Trustee to institute proceedings in
          respect of such Event of Default as Trustee and offered the
          Trustee reasonable indemnity, and the Trustee shall not have
          received from the Holders of a majority in aggregate principal
          amount of Securities of all series at the time Outstanding in
          respect of which an Event of Default shall have occurred and be
          continuing a direction inconsistent with such request, and shall
          have failed to institute any such proceeding, for 60 days after
          receipt of such notice, request and offer of indemnity.  The
          foregoing shall not apply to any suit instituted by the Holder of
          this Security for the enforcement of any payment of principal
          hereof or any premium or interest hereon on or after the
          respective due dates expressed herein.

                    No reference herein to the Indenture and no provision
          of this Security or of the Indenture shall alter or impair the
          obligation of the Company, which is absolute and unconditional,
          to pay the principal of and any premium and interest on this
          Security at the times, place and rate, and in the coin or
          currency, herein prescribed.

                    Pursuant to Section 311 of the Indenture, so long as
          the Company is not in default in the payment of interest on the
          Securities of any series under the Indenture, the Company shall
          have the right, at any time and from time to time during the term
          of the Securities of this series, to extend the interest payment
          period to a period not exceeding 20 consecutive quarterly periods
          (an "Extension Period") during which period interest (calculated
          for each Interest Period (as defined in the Officer's
          Certificate) in the manner provided for in paragraph (4) of the
          Officer's Certificate, as if the interest payment period had not
          been so extended) will be compounded quarterly.  At the end of
          the Extension Period, the Company shall pay all interest accrued
          and unpaid hereon (together with interest thereon at the rate
          specified for the Securities of this series, compounded
          quarterly, to the extent permitted by applicable law) and
          Additional Interest, if any; provided, however, that during any
          such Extension Period, the Company shall not declare or pay any
          dividend or distribution (other than a dividend or distribution
          in common stock of the Company) on, or redeem, purchase, acquire
          or make a liquidation payment with respect to, any of its capital
          stock, make any payment of principal, interest or premium, if
          any, on or repay, repurchase or redeem any indebtedness that is
          pari passu with the Securities of this series, or make any
          guarantee payments with respect to the foregoing ("Restricted
          Payments").  Prior to the termination of any such Extension
          Period, the Company may further extend the interest payment
          period, provided that such Extension Period together with all
          such previous and further extensions thereof shall not exceed 20
          consecutive quarterly periods at any one time or extend beyond
          the Maturity of the Securities of this series.  Any Extension
          Period with respect to payment of interest on the Securities of
          this series, or any extended interest payment period in respect
          of similar securities will apply to the Securities of this series
          and all such securities and will also apply to distributions with
          respect to the Preferred Trust Securities and all other
          securities with terms substantially the same as the Preferred
          Trust Securities.  Upon the termination of any such Extension
          Period and the payment of all amounts then due, including
          interest on deferred interest payments, the Company may elect to
          begin a new Extension Period, subject to the above requirements.
          No interest shall be due and payable during an Extension Period,
          except at the end thereof.  The Company shall give the Trustee
          notice of its election of an Extension Period prior to the
          earlier of (i) one Business Day prior to the record date for the
          distribution which would occur but for such election or (ii) the
          date the Company is required to give notice to any securities
          exchange on which the Securities may be listed or any other
          applicable self-regulatory organization of the record date.

                    The Securities of this series are issuable only in
          registered form without coupons in denominations of $      and
                                                               -----
          any integral multiple thereof.  As provided in the Indenture and
          subject to certain limitations therein set forth, Securities of
          this series are exchangeable for a like aggregate principal
          amount of Securities of this series and of like tenor and of
          authorized denominations, as requested by the Holder surrendering
          the same.

                    No service charge shall be made for any such
          registration of transfer or exchange, but the Company may require
          payment of a sum sufficient to cover any tax or other
          governmental charge payable in connection therewith.

                    The Company, the Trustee and any agent of the Company
          or the Trustee may treat the Person in whose name this Security
          is registered as the absolute owner hereof for all purposes,
          whether or not this Security be overdue, and neither the Company,
          the Trustee nor any such agent shall be affected by notice to the
          contrary.

                    All terms used in this Security which are defined in
          the Indenture shall have the meanings assigned to them in the
          Indenture.

waived pursuant to Section 2.06), and is actually known to a Responsible Officer

rights and powers vested in it by this Guarantee Agreement, and use the same
degree of care and skill in its exercise thereof, as a prudent person would
exercise or use under the circumstances in the conduct of his or her own
affairs.

          (c) No provision of this Guarantee Agreement shall be construed to
relieve the Guarantee Trustee from liability for its own negligent action, its
own negligent failure to act, or its own willful misconduct, except that:

               (i)  prior to the occurrence of any Event of Default and
          after the curing or waiving of all such Events of Default that may
          have occurred:

                    (A)  the duties and obligations of the Guarantee Trustee
               shall be determined solely by the express provisions of this
               Guarantee Agreement, and the Guarantee Trustee shall not be
               liable except for the performance of such duties and obligations
               as are specifically set forth in this Guarantee Agreement, and no

                                       -6-

               truth of the statements and the correctness of the opinions
               expressed therein, upon any certificates or opinions furnished to
               the Guarantee Trustee and conforming to the requirements of this
               Guarantee Agreement; but in the case of any such certificates or
               opinions that by any provision hereof are specifically required
               to be furnished to the Guarantee Trustee, the Guarantee Trustee
               shall be under a duty to examine the same to determine whether or
               not they conform to the requirements of this Guarantee Agreement;

               (ii) the Guarantee Trustee shall not be liable for any error of
          judgment made in good faith by a Responsible Officer of the Guarantee
          Trustee, unless it shall be proved that the Guarantee Trustee was
          negligent in ascertaining the pertinent facts upon which such judgment
          was made;

               (iii) the Guarantee Trustee shall not be liable with respect to
          any action taken or omitted to be taken by it in good faith in
          accordance with the direction of the Holders of a Majority in
          Liquidation Amount of the Preferred Trust Securities relating to the
          time, method and place of conducting any proceeding for any remedy
          available to the Guarantee Trustee, or exercising any trust or power
          conferred upon the Guarantee Trustee under this Guarantee Agreement;
          and

               (iv) no provision of this Guarantee Agreement shall require the

          any financial liability in the performance of any of its duties
          hereunder, or in the exercise of any of its rights or powers, if the
          Guarantee Trustee shall have reasonable grounds for believing that the
          repayment of such funds or liability is not reasonably assured to it
          under the terms of this Guarantee Agreement or adequate indemnity,
          reasonably satisfactory to the Guarantee Trustee, against such risk or
          liability is not reasonably assured to it.

          of Columbia authority. If such corporation publishes reports of
          condition at least annually, pursuant to law or to the requirements of

     resign in the manner and with the effect set out in Section 4.03(c).

          (c) If the Guarantee Trustee has or shall acquire any "conflicting
     interest" within the meaning of Section 310(b) of the Trust Indenture Act,
     the Guarantee Trustee and Guarantor shall in all respects comply with the
     provisions of Section 310(b) of the Trust Indenture Act.

          SECTION 4.02 COMPENSATION AND REIMBURSEMENT.

          The Guarantor agrees:

          (a)  to pay the Guarantee Trustee from time to time such reasonable
compensation as the Guarantor and the Guarantee Trustee shall from time to time
agree in writing for all services rendered by it hereunder (which compensation
shall not be limited by any provision of law in regard to the compensation of a
trustee of an express trust);

          (b)  except as otherwise expressly provided herein, to reimburse the
Guarantee Trustee upon its request for all reasonable expenses, disbursements

                                      -10-

and advances incurred or made by the Guarantee Trustee in accordance with the
provisions of this Guarantee Agreement (including the reasonable compensation
and expenses of its agents and counsel), except any such expense, disbursement
or advance as may be attributable to its negligence or bad faith; and

          (c)  to indemnify each of the Guarantee Trustee and any predecessor
Guarantee Trustee for, and to hold it harmless from and against, any and all
loss, damage, claim, liability or expense, including taxes (other than taxes
based upon the income of the Guarantee Trustee) incurred without negligence or
bad faith on its part, arising out of or in connection with the acceptance of
the trusts created by, or the administration of, this Guarantee Agreement,
including the costs and expenses of defending itself against any claim or
liability in connection with the exercise or performance of any of its powers or
duties hereunder.

          As security for the performance of the obligations of the Guarantor
under this Section, the Guarantee Trustee shall have a lien prior to the
Preferred Trust Securities upon all the property and funds held or collected by
the Guarantee Trustee as such, except funds held in trust for the payment of
principal of, and premium (if any) or interest on, particular obligations of the
Guarantor under this Guarantee Agreement.

          The provisions of this Section shall survive the termination of this
Guarantee Agreement.

          SECTION 4.03 APPOINTMENT, REMOVAL AND RESIGNATION OF GUARANTEE
TRUSTEE.

          (a) Subject to Section 4.03(b), unless an Event of Default shall have
occurred and be continuing, the Guarantee Trustee may be appointed or removed
without cause at any time by the Guarantor.

          (b) The Guarantee Trustee shall not be removed until a Successor
Guarantee Trustee has been appointed and has accepted such appointment by
written instrument executed by such Successor Guarantee Trustee and delivered to
the Guarantor.

          (c) The Guarantee Trustee appointed to office shall hold office until
a Successor Guarantee Trustee shall have been appointed or until its removal or
resignation. The Guarantee Trustee may resign from office (without need for
prior or subsequent accounting) by an instrument in writing executed by the
Guarantee Trustee and delivered to the Guarantor, which resignation shall not
take effect until a Successor Guarantee Trustee has been appointed and has
accepted such appointment by instrument in writing executed by such Successor
Guarantee Trustee and delivered to the Guarantor and the resigning Guarantee
Trustee.

          (d) If no Successor Guarantee Trustee shall have been appointed and
accepted appointment as provided in this Section 4.03 within 60 days after


                                      -11-


<PAGE>


delivery to the Guarantor of an instrument of resignation or removal, the
Guarantee Trustee resigning or being removed may petition any court of competent
jurisdiction for appointment of a Successor Guarantee Trustee. Such court may
thereupon, after prescribing such notice, if any, as it may deem proper, appoint
a Successor Guarantee Trustee.

          (e) The Guarantor shall give notice of each resignation and each
removal of the Guarantee Trustee and each appointment of a successor Guarantee

of its Corporate Trust Office.

          (f) No Guarantee Trustee shall be liable for the acts or omissions to
act of any Successor Guarantee Trustee.

                                    GUARANTEE

          SECTION 5.01 GUARANTEE. The Guarantor irrevocably and unconditionally
agrees to pay in full to the Holders the Guarantee Payments (without duplication
of amounts theretofore paid by or on behalf of the Issuer), as and when due,
regardless of any defense, right of set-off or counterclaim which the Issuer may
have or assert. The Guarantor's obligation to make a Guarantee Payment may be
satisfied by direct payment of the required amounts by the Guarantor to the
Holders or by causing the Issuer to pay such amounts to the Holders.

          SECTION 5.02 WAIVER OF NOTICE AND DEMAND. The Guarantor hereby waives
notice of acceptance of this Guarantee Agreement and of any liability to which
it applies or may apply, presentment, demand for payment, any right to require a
proceeding first against the Guarantee Trustee, Issuer or any other Person
before proceeding against the Guarantor, protest, notice of nonpayment, notice
of dishonor, notice of redemption and all other notices and demands.

          SECTION 5.03 OBLIGATIONS NOT AFFECTED. The obligation of the Guarantor
to make the Guarantee Payments under this Guarantee Agreement shall in no way be
affected or impaired by reason of the happening from time to time of any of the
following:

          (a) the release or waiver, by operation of law or otherwise, of the
     performance or observance by the Issuer of any express or implied
     agreement, covenant, term or condition relating to the Preferred Trust
     Securities to be performed or observed by the Issuer;

          (b) the extension of time for the payment by the Issuer of all or any
     portion of the Distributions, Redemption Price, Liquidation Distribution or


                                      -12-


<PAGE>


     any other sums payable under the terms of the Preferred Trust Securities or
     the extension of time for the performance of any other obligation under,
     arising out of, or in connection with, the Preferred Trust Securities
     (other than an extension of time for payment of Distributions, Redemption
     Price, Liquidation Distribution or other sum payable that results from the
     extension of any interest payment period on the Debentures permitted by the
     Subordinated Indenture);

          (c) any failure, omission, delay or lack of diligence on the part of
     the Property Trustee or the Holders to enforce, assert or exercise any
     right, privilege, power or remedy conferred on the Property Trustee or the
     Holders pursuant to the terms of the Preferred Trust Securities, or any
     action on the part of the Issuer granting indulgence or extension of any
     kind;

          (d) the voluntary or involuntary liquidation, dissolution, sale of any
     collateral, receivership, insolvency, bankruptcy, assignment for the
     benefit of creditors, reorganization, arrangement, composition or
     readjustment of debt of, or other similar proceedings affecting, the Issuer
     or any of the assets of the Issuer;

          (e) any invalidity of, or defect or deficiency in, the Preferred Trust
     Securities;

          (f) the settlement or compromise of any obligation guaranteed hereby
     or hereby incurred; or

          (g) any other circumstance whatsoever that might otherwise constitute
     a legal or equitable discharge or defense of a guarantor, it being the
     intent of this Section 5.03 that the obligations of the Guarantor hereunder
     shall be absolute and unconditional under any and all circumstances.

There shall be no obligation of the Guarantee Trustee, the Property Trustee or
the Holders to give notice to, or obtain consent of, the Guarantor or any other
Person with respect to the happening of any of the foregoing.

          SECTION 5.04 RIGHTS OF HOLDERS. The Guarantor expressly acknowledges
that: (i) this Guarantee Agreement will be deposited with the Guarantee Trustee
to be held for the benefit of the Holders; (ii) if an Event of Default has
occurred and is continuing, the Guarantee Trustee has the right to enforce this
Guarantee Agreement on behalf of the Holders; (iii) the Holders of a Majority in
Liquidation Amount of the Preferred Trust Securities have the right to direct
the time, method and place of conducting any proceeding for any remedy available
to the Guarantee Trustee in respect of this Guarantee Agreement or exercising
any trust or power conferred upon the Guarantee Trustee under this Guarantee
Agreement; and (iv) if the Guarantee Trustee fails to enforce this Guarantee
Agreement, any Holder may enforce this Guarantee Agreement, or institute a legal
proceeding directly against the Guarantor to enforce the Guarantee Trustee's


                                      -13-


<PAGE>


rights under this Guarantee Agreement without first instituting a legal
proceeding against the Issuer, the Guarantee Trustee, or any other Person.

          SECTION 5.05 GUARANTEE OF PAYMENT. This Guarantee Agreement creates a
guarantee of payment and not of collection. This Guarantee Agreement will not be
discharged except by payment of the Guarantee Payments in full (without
duplication).

          SECTION 5.06 SUBROGATION. The Guarantor shall be subrogated to all, if
any, rights of the Holders against the Issuer in respect of any amounts paid to
the Holders by the Guarantor under this Guarantee Agreement; provided, however,
that the Guarantor shall not (except to the extent required by mandatory
provisions of law) be entitled to enforce or exercise any rights which it may
acquire by way of subrogation or any indemnity, reimbursement or other
agreement, in all cases as a result of payment under this Guarantee Agreement,
if, at the time of any such payment, any amounts of Guarantee Payments are due
and unpaid under this Guarantee Agreement. If any amount shall be paid to the
Guarantor in violation of the preceding sentence, the Guarantor agrees to hold
such amount in trust for the Holders and to pay over such amount to the Holders.

          SECTION 5.07 INDEPENDENT OBLIGATIONS. The Guarantor acknowledges that
its obligations hereunder are independent of the obligations of the Issuer with
respect to the Preferred Trust Securities and that the Guarantor shall be liable
as principal and as debtor hereunder to make Guarantee Payments pursuant to the
terms of this Guarantee Agreement notwithstanding the occurrence of any event
referred to in subsections (a) through (g), inclusive, of Section 5.03.


                                   ARTICLE VI

                                  SUBORDINATION

          SECTION 6.01 SUBORDINATION. This Guarantee Agreement will constitute
an unsecured obligation of the Guarantor and will rank (i) subordinate and
junior in right of payment to all other liabilities of the Guarantor, including
the Debentures, except those made pari passu or subordinate by their terms,
(ii) pari passu with the most senior preferred or preference stock now or
hereafter issued by the Guarantor and with any guarantee now or hereafter
entered into by the Guarantor in respect of any preferred or preference stock of
any Affiliate of the Guarantor, and (iii) senior to all common stock of the
Guarantor. Nothing in this Section 6.01 shall apply to claims of, or payments
to, the Guarantee Trustee under or pursuant to Section 4.02 hereof.

                                   TERMINATION

          SECTION 7.01 TERMINATION. Subject to Section 4.02 hereof, this
Guarantee Agreement shall terminate and be of no further force and effect upon:
(i) full payment of the Redemption Price of all Preferred Trust Securities, and
all accrued and unpaid Distributions to the date of redemption, (ii) the
distribution of Debentures to Holders in exchange for all of the Preferred Trust
Securities, or (iii) full payment of the amounts payable in accordance with the
Trust Agreement upon liquidation of the Issuer. Notwithstanding the foregoing,
this Guarantee Agreement will continue to be effective or will be reinstated, as
the case may be, if at any time any Holder must restore payment of any sums paid
with respect to Preferred Trust Securities or under this Guarantee Agreement.


                                  ARTICLE VIII

                                  MISCELLANEOUS

          SECTION 8.01 SUCCESSORS AND ASSIGNS. All guarantees and agreements
contained in this Guarantee Agreement shall bind the successors, assigns,
receivers, trustees and representatives of the Guarantor and shall inure to the
benefit of the Holders of the Preferred Trust Securities then outstanding.
Except in connection with a consolidation, merger or sale involving the
Guarantor that is permitted under Article Eleven of the Subordinated Indenture,
the Guarantor shall not assign its obligations hereunder.

          SECTION 8.02 AMENDMENTS. This Guarantee Agreement may be amended only
by an instrument in writing entered into by the Guarantor and the Guarantee
Trustee. Except with respect to any changes which do not materially adversely
affect the rights of Holders (in which case no consent of Holders will be
required), this Guarantee Agreement may only be amended with the prior approval
of the Holders of not less than 66 2/3% in aggregate Liquidation Amount of all
the outstanding Preferred Trust Securities. The provisions of Article VI of the
Trust Agreement concerning meetings of Holders shall apply to the giving of such
approval. Nothing herein contained shall be deemed to require that the Guarantee
Trustee enter into any amendment of this Guarantee Agreement.

          Ladies and Gentlemen:

               Reference is made to the Registration Statement
          (Registration Statement) on Form S-3 to be filed by TXU Gas
          Company (Company), formerly known as ENSERCH Corporation, and TXU
          Gas Capital II, TXU Gas Capital III and TXU Gas Capital IV
          (Trusts) on or about the date hereof, with the Securities and
          Exchange Commission under the Securities Act of 1933, as amended,
          for the registration of (i) securities in an aggregate offering
          amount of $500,000,000, including (a) unsecured debt securities
          (Debt Securities) of the Company to be issued pursuant to the
          terms of the Indenture (For Unsecured Debt Securities), dated as
          of January 1, 1998 between the Company and The Bank of New York
          (Debt Securities Indenture); and (b) preferred trust securities
          (Preferred Trust Securities) of one or more of the Trusts; (ii)
          the guarantee of the Company with respect to the Preferred Trust
          Securities (the Guarantee); and (iii) the Company's Junior
          Subordinated Debentures (Subordinated Debentures) to be issued
          pursuant to the terms of the Subordinated Indenture, dated June
          1, 1998, between the Company and The Bank of New York
          (Subordinated Indenture) and purchased by one or more of the
          Trusts with the proceeds of the sale of Preferred Trust
          Securities.  In connection therewith, we have reviewed such
          documents and records as we have deemed necessary to enable us to
          express an opinion on the matters covered hereby.

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

               1.   The Company is a corporation validly organized and
          existing under the laws of the State of Texas.

               2.   All requisite action necessary to make any Debt
          Securities valid, legal and binding obligations of the Company
          will have been taken when the Board of Directors of the Company,
          or an officer duly authorized thereby, shall have taken such
          action, pursuant to the terms of the Debt Securities Indenture,
          as may be necessary to establish the terms of such Debt
          Securities, and such Debt Securities shall have been issued and
          delivered in accordance with the terms and provisions of such
          Debt Securities Indenture.

               3.   All requisite action necessary to make the Guarantee a
          valid, legal and binding obligation of the Company will have been
          taken when the Board of Directors of the Company, or an officer
          duly authorized thereby, shall have taken such action as may be
          necessary to establish the terms of the Guarantee and the
          Guarantee shall have been duly executed and delivered by the
          parties thereto.

               4.   All requisite action necessary to make the Subordinated
          Debentures valid, legal and binding obligations of the Company
          will have been taken when the Board of Directors of the Company,
          or an officer duly authorized thereby, shall have taken such
          action, pursuant to the terms of the Subordinated Indenture, as
          may be necessary to establish the terms of the Subordinated
          Debentures, and the Subordinated Debentures shall have been
          issued and delivered in accordance with the terms and provisions
          of the Subordinated Indenture.

                    We are members of the State Bar of Texas and do not
          hold ourselves out as experts on the laws of New York.  As to all
          matters of New York law, we have with your consent relied upon an

          Ladies and Gentlemen:

               Reference is made to the Registration Statement
          (Registration Statement) on Form S-3 to be filed by TXU Gas
          Company (Company), formerly known as ENSERCH Corporation, and TXU
          Gas Capital II, TXU Gas Capital III and TXU Gas Capital IV
          (Trusts) on or about the date hereof, with the Securities and
          Exchange Commission under the Securities Act of 1933, as amended,
          for the registration of (i) securities in an aggregate offering
          amount of $500,000,000, including (a) unsecured debt securities
          (Debt Securities) of the Company to be issued pursuant to the
          terms of the Indenture (For Unsecured Debt Securities), dated as
          of January 1, 1998 between the Company and The Bank of New York
          (Debt Securities Indenture); and (b) preferred trust securities
          (Preferred Trust Securities) of one or more of the Trusts; (ii)
          the guarantee of the Company with respect to the Preferred Trust
          Securities (the Guarantee); and (iii) the Company's Junior
          Subordinated Debentures (Subordinated Debentures) to be issued
          pursuant to the terms of the Subordinated Indenture, dated June
          1, 1998, between the Company and The Bank of New York
          (Subordinated Indenture) and purchased by one or more of the
          Trusts with the proceeds of the sale of Preferred Trust
          Securities.  In connection therewith, we have reviewed such
          documents and records as we have deemed necessary to enable us to
          express an opinion on the matters covered hereby.

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

               1.   The Company is a corporation validly organized and
          existing under the laws of the State of Texas.

               2.   All requisite action necessary to make any Debt
          Securities valid, legal and binding obligations of the Company
          will have been taken when the Board of Directors of the Company,
          or an officer duly authorized thereby, shall have taken such
          action, pursuant to the terms of the Debt Securities Indenture,
          as may be necessary to establish the terms of such Debt
          Securities, and such Debt Securities shall have been issued and
          delivered in accordance with the terms and provisions of such
          Debt Securities Indenture.

               3.   All requisite action necessary to make the Guarantee a
          valid, legal and binding obligation of the Company will have been
          taken when the Board of Directors of the Company, or an officer
          duly authorized thereby, shall have taken such action as may be
          necessary to establish the terms of the Guarantee and the
          Guarantee shall have been duly executed and delivered by the
          parties thereto.

               4.   All requisite action necessary to make the Subordinated
          Debentures valid, legal and binding obligations of the Company
          will have been taken when the Board of Directors of the Company,
          or an officer duly authorized thereby, shall have taken such
          action, pursuant to the terms of the Subordinated Indenture, as
          may be necessary to establish the terms of the Subordinated
          Debentures, and the Subordinated Debentures shall have been
          issued and delivered in accordance with the terms and provisions
          of the Subordinated Indenture.

                    We are members of the New York Bar and do not hold
          ourselves out as experts on the laws of Texas.  As to all matters
          of Texas law, we have with your consent relied upon an opinion of
          even date herewith addressed to you by Worsham, Forsythe &
          Wooldridge, L.L.P. of Dallas, Texas.

                    We hereby consent to the use of this opinion as an
          exhibit to the Registration Statement and to the use of our name
          as counsel in the Registration Statement.

                  Re:      TXU Gas Capital II
                           ------------------

Ladies and Gentlemen:

                  We have acted as special Delaware counsel for TXU Gas Company,
a Texas corporation (the "Company"), and TXU Gas Capital II, a Delaware business
trust (the "Trust"), in connection with the matters set forth herein. At your
request, this opinion is being furnished to you.

                  For purposes of giving the opinions hereinafter set forth, our
examination of documents has been limited to the examination of originals or
copies of the following:

                  (a) The Certificate of Trust of the Trust, dated as of August
18, 1999 (the "Certificate"), as filed in the office of the Secretary of State
of the State of Delaware (the "Secretary of State") on August 18, 1999;

                  (b) The Trust Agreement of the Trust, dated as of August 18,
1999, among the Company and the trustees of the Trust named therein;

                  (c) The Registration Statement (the "Registration Statement")
on Form S-3, including a preliminary prospectus (the "Prospectus"), relating to
the preferred undivided beneficial interests in the assets of the Trust (each, a
"Preferred Trust Security" and collectively, the "Preferred Trust Securities"),
as proposed to be filed by the Trust, the Company and others with the Securities
and Exchange Commission on or about August 23, 1999;

                  (d) A form of Amended and Restated Trust Agreement of the
Trust (including Exhibits A, B and D thereto) (the "Trust Agreement"), to be
entered into among the Company, the trustees of the Trust named therein, and the
holders, from time to time, of undivided beneficial interests in the assets of
the Trust, filed as an exhibit to the Registration Statement; and

                  (e) A Certificate of Good Standing for the Trust, dated August
23, 1999, obtained from the Secretary of State.

                  Initially capitalized terms used herein and not otherwise
defined are used as defined in the Trust Agreement.

                  For purposes of this opinion, we have not reviewed any
documents other than the documents listed in paragraphs (a) through (e) above.
In particular, we have not reviewed any document (other than the documents
listed in paragraphs (a) through (e) above) that is referred to in or
incorporated by reference into the documents reviewed by us. We have assumed
that there exists no provision in any document that we have not reviewed that is
inconsistent with the opinions stated herein. We have conducted no independent
factual investigation of our own but rather have relied solely upon the
foregoing documents, the statements and information set forth therein and the
additional matters recited or assumed herein, all of which we have assumed to be
true, complete and accurate in all material respects.

                  With respect to all documents examined by us, we have assumed
(i) the authenticity of all documents submitted to us as authentic originals,
(ii) the conformity with the originals of all documents submitted to us as
copies or forms, and (iii) the genuineness of all signatures.

                  For purposes of this opinion, we have assumed (i) that the
Trust Agreement constitutes the entire agreement among the parties thereto with
respect to the subject matter thereof, including with respect to the creation,
operation and termination of the Trust, and that the Trust Agreement and the
Certificate are in full force and effect and have not been amended, (ii) except
to the extent provided in paragraph 1 below, the due creation or due
organization or due formation, as the case may be, and valid existence in good
standing of each party to the documents examined by us under the laws of the
jurisdiction governing its creation, organization or formation, (iii) the legal
capacity of natural persons who are signatories to the documents examined by us,
(iv) that each of the parties to the documents examined by us has the power and
authority to execute and deliver, and to perform its obligations under, such
documents, (v) the due authorization, execution and delivery by all parties
thereto of all documents examined by us, (vi) the receipt by each Person to whom
a Preferred Trust Security is to be issued by the Trust (collectively, the
"Securityholders") of a Preferred Trust Securities Certificate in the form
attached as Exhibit D to the Trust Agreement evidencing ownership of such
Preferred Trust Security in the name of such Person and the payment for the
Security acquired by it, in accordance with the Trust Agreement and the
Registration Statement, and (vii) that the Preferred Trust Securities are
issued and sold to the Securityholders in accordance with the Trust Agreement
and the Registration Statement. We have not participated in the preparation of
the Registration Statement and assume no responsibility for its contents.

                  This opinion is limited to the laws of the State of Delaware
(excluding the securities laws of the State of Delaware), and we have not
considered and express no opinion on the laws of any other jurisdiction,
including federal laws and rules and regulations relating thereto. Our opinions
are rendered only with respect to Delaware laws and rules, regulations and
orders thereunder that are currently in effect.

                  Based upon the foregoing, and upon our examination of such
questions of law and statutes of the State of Delaware as we have considered
necessary or appropriate, and subject to the assumptions, qualifications,
limitations and exceptions set forth herein, we are of the opinion that:

                  1. The Trust has been duly created and is validly existing in
good standing as a business trust under the Delaware Business Trust Act.

                  2. The Preferred Trust Securities will represent valid and,
subject to the qualifications set forth in paragraph 3 below, fully paid and
nonassessable undivided beneficial interests in the assets of the Trust.

                  3. The Securityholders, as beneficial owners of the Trust,
will be entitled to the same limitation of personal liability extended to
stockholders of private corporations for profit organized under the General
Corporation Law of the State of Delaware. We note that the Securityholders may
be obligated to make payments as set forth in the Trust Agreement.

                  We consent to the filing of this opinion with the Securities
and Exchange Commission as an exhibit to the Registration Statement. In
addition, we hereby consent to the use of our name under the heading "Experts
and Legality" in the Prospectus. In giving the foregoing consents, we do not
thereby admit that we come within the category of Persons whose consent is
required under Section 7 of the Securities Act of 1933, as amended, or the rules
and regulations of the Securities and Exchange Commission thereunder. Except as
stated above, without our prior written consent, this opinion may not be
furnished or quoted to, or relied upon by, any other Person for any purpose.

                                       Very truly yours,

jurisdiction governing its creation, organization or formation, (iii) the legal
capacity of natural persons who are signatories to the documents examined by us,
(iv) that each of the parties to the documents examined by us has the power and

Preferred Trust Security in the name of such Person and the payment for the
Security acquired by it, in accordance with the Trust Agreement and the
Registration Statement, and (vii) that the Preferred Trust Securities are

                  This opinion is limited to the laws of the State of Delaware
(excluding the securities laws of the State of Delaware), and we have not
considered and express no opinion on the laws of any other jurisdiction,
including federal laws and rules and regulations relating thereto. Our opinions
are rendered only with respect to Delaware laws and rules, regulations and
orders thereunder that are currently in effect.

                  Based upon the foregoing, and upon our examination of such
questions of law and statutes of the State of Delaware as we have considered
necessary or appropriate, and subject to the assumptions, qualifications,
limitations and exceptions set forth herein, we are of the opinion that:

                  1. The Trust has been duly created and is validly existing in
good standing as a business trust under the Delaware Business Trust Act.

                  2. The Preferred Trust Securities will represent valid and,
subject to the qualifications set forth in paragraph 3 below, fully paid and
nonassessable undivided beneficial interests in the assets of the Trust.

                  3. The Securityholders, as beneficial owners of the Trust,
will be entitled to the same limitation of personal liability extended to
stockholders of private corporations for profit organized under the General
Corporation Law of the State of Delaware. We note that the Securityholders may
be obligated to make payments as set forth in the Trust Agreement.

                  We consent to the filing of this opinion with the Securities
and Exchange Commission as an exhibit to the Registration Statement. In
addition, we hereby consent to the use of our name under the heading "Experts
and Legality" in the Prospectus. In giving the foregoing consents, we do not
thereby admit that we come within the category of Persons whose consent is
required under Section 7 of the Securities Act of 1933, as amended, or the rules
and regulations of the Securities and Exchange Commission thereunder. Except as
stated above, without our prior written consent, this opinion may not be
furnished or quoted to, or relied upon by, any other Person for any purpose.

                                        Very truly yours,

(1)      "Earnings" represent the aggregate of (a) net income (loss), (b) income
         taxes, and (c) fixed charges deducted from earnings, on a total
         enterprise basis. "Fixed Charges" represent interest expense,
         distributions on trust securities of subsidiaries, capitalized interest
         and the portion of rental expense representative of the interest
         factor.

(2)      The preferred stock dividend requirements are assumed to be equal to
         the pretax earnings which would be required to cover such dividend
         requirements. The amount of such pretax earnings required to cover
         preferred stock dividends was computed using tax rates for the
         applicable period.

(3)      For the six months ended June 30, 1999, fixed charges exceeded earnings
         by $27.4 million.

(4)      For the six months ended June 30, 1999, combined fixed charges and
         preferred dividends exceeded earnings by $29.7 million.
